Summary
Technical Problem
[0004] However, if a plurality of linear materials is joined to each other over the entire
region of an upper, the stiffness is increased in the entire region of the upper due
to the joint of the linear materials. This causes, for example, deterioration in the
followability of the upper with respect to bending and twisting of a foot during movement,
fatigue failure of the materials during bending of a foot, and other problems.
[0005] The present invention has been made in view of the above, and a purpose of the present
invention is to obtain an upper capable of reducing the stiffness of the upper.
Solution to Problem
[0006] In order to solve the above problem and achieve the object, an upper includes an
upper body covering the instep of a foot. At least a part of the upper body is an
opening region disposed with an opening. In the opening region, a plurality of first
members extending in one direction is disposed in a state of not being coupled with
each other. Both ends of the plurality of first member are fixed ends fixed to a portion
of the upper body adjacent to the opening region. The order in which fixed ends on
one end side of the plurality of first members are arranged is equal to the order
in which fixed ends on the other end side of the plurality of first members are arranged.
Advantageous Effects of Invention
[0007] An upper according to the present invention has an effect of reducing the stiffness
of the upper.

[0009] Hereinafter, embodiments of an upper according to the present invention and a shoe
including the same will be described in detail with reference to the drawings. Note
that the present invention is not limited by the embodiments.
[0010] In the following embodiments, a direction in which a shoe center axis, which is a
perpendicular line passing through a shoe center in a plan view of a shoe, extends
is referred to as a front-rear direction, and a direction orthogonal to the front-rear
direction in a plan view of the shoe is referred to as a right-left direction.
[0011] In addition, of the front-rear direction, a direction directed from the end on the
side where a portion of an upper covering the rearfoot of a foot is positioned toward
the end on the side where a portion covering the forefoot of the foot is positioned
is referred to as a front side, and of the front-rear direction, a direction directed
from the end on the side where a portion of the upper covering the forefoot of the
foot is positioned toward the end on the side where a portion of the upper covering
the rearfoot of the foot is positioned is referred to as a rear side.
[0012] In addition, a median side of a foot in the anatomical position is referred to as
a medial foot side, and the side opposite to the median side of the foot in the anatomical
position is referred to as a lateral foot side. That is, the side closer to the median
line in the anatomical position is referred to as the medial foot side, and the side
farther from the median line in the anatomical position is referred to as the lateral
foot side.
[0013] In addition, when a line along the right-left direction passing through a position
corresponding to 25% to 50% of the dimension in the front-rear direction of the upper
from the front end of the upper is defined as a first boundary line, and a line along
the right-left direction passing through a position corresponding to 55% to 80% of
the dimension in the front-rear direction of the upper from the front end of the upper
is defined as a second boundary line, a portion positioned in front of the first boundary
line is referred to as an upper forefoot portion, a portion sandwiched between the
first boundary line and the second boundary line is referred to as an upper midfoot
portion, and a portion positioned behind the second boundary line is referred to as
an upper rearfoot portion.
[0014] The upper forefoot portion corresponds to a portion covering the forefoot of a foot
of a wearer with a standard body shape, the upper midfoot portion corresponds to a
portion covering the midfoot of a foot of a wearer with a standard body shape, and
the upper rearfoot portion corresponds to a portion covering the rearfoot of a foot
of a wearer with a standard body shape. In other words, the first boundary line is
a line roughly along the MP joint of a wearer with a standard body shape, and the
second boundary line is a line roughly along the Chopart joint of a wearer with a
standard body shape.
[0015] Furthermore, a height direction means a direction orthogonal to both the front-rear
direction and the right-left direction unless otherwise specified, and a thickness
means a dimension in the height direction unless otherwise specified.
(First embodiment)
[0016] FIG. 1 is a plan view of a shoe 1 according to a first embodiment of the present
invention. FIG. 2 is a side view of the shoe 1 on a lateral foot side according to
the first embodiment. In FIG. 1, only the shoe 1 for a left foot is illustrated. Since
the shoe 1 has a right-left symmetrical structure for a left foot and a right foot,
only the shoe 1 for a left foot is described in the present embodiment, and the description
of the shoe 1 for a right foot is omitted. The shoe 1 is, for example, a shoe for
running or walking, a shoe for climbing, or a shoe for sports such as tennis and basketball.
As illustrated in FIG. 2, the shoe 1 includes an upper 2 and a sole 3 positioned below
the upper 2.
[0017] As illustrated in FIG. 1, the upper 2 includes an upper body 20, a shoe tongue 21,
and a shoelace 22.
[0018] The upper body 20 mainly covers a part on the instep side of a foot. At the upper
portion of the upper body 20, a foot insertion opening 20a for inserting a foot of
a wearer and a throat portion 20b communicating with the foot insertion opening 20a
and extending from the foot insertion opening 20a to the front side are disposed.
At least a part of the upper body 20 is an opening region 4 disposed with an opening.
In the opening region 4, a plurality of first members 5 extending in one direction
are disposed in a state of not being coupled with each other. Details of the opening
region 4 and the first members 5 are described later. Although the first members 5
are actually linear, in FIGS. 1 and 2, the first members 5 are illustrated in a band
shape hatched with oblique lines for ease of understanding.
[0019] The shoe tongue 21 is a member for protecting the instep of a wearer. The shoe tongue
21 covers the throat portion 20b inside the upper body 20. The shoe tongue 21 is fixed
to the upper body 20 by stitching, welding, bonding, or a combination thereof. As
the material of the upper body 20 and the shoe tongue 21, woven fabric, knitted fabric,
synthetic leather, or resin is used for example. In particular, in the shoe 1 required
to have air permeability and lightweight property, a double raschel warp knitted fabric
knitted with polyester yarn is preferably used as the material of the upper body 20
and the shoe tongue 21. Note that the material of the upper body 20 and the shoe tongue
21 is not limited to those exemplified.
[0020] The shoelace 22 is a string-like member alternately hooked to the first members 5
disposed on both side edges of the throat portion 20b in the right-left direction,
and is detachably attached to the upper body 20.
[0021] As illustrated in FIG. 2, the sole 3 covers the sole of a foot. The sole 3 includes
an outsole 30 and a midsole 31. The sole 3 is fixed to the upper body 20 by stitching,
welding, bonding, or a combination thereof. The lower surface of the outsole 30 serves
as a ground contact surface 30a to be contacted on the ground. The midsole 31 is positioned
on the upper surface of the outsole 30 and has a cushioning property. Note that the
outsole 30 may be integrated with the midsole 31. The midsole 31 integrated with the
outsole 30 is also referred to as a "unisole".
[0022] Next, the structure of the upper body 20 is described in more detail with reference
to FIG. 3. FIG. 3 is a developed view of the upper 2 according to the first embodiment.
[0023] As illustrated in FIG. 3, the upper body 20 includes an upper forefoot portion 23
which is a portion covering a forefoot of a foot of a wearer with a standard body
shape, an upper midfoot portion 24 which is a portion covering a midfoot of a foot
of a wearer with a standard body shape, an upper rearfoot portion 25 which is a portion
covering a rearfoot of a foot of a wearer with a standard body shape, and an upper
sole portion 26 which is a portion covering a sole of a wearer with a standard body
shape. The upper forefoot portion 23, the upper midfoot portion 24, and the upper
rearfoot portion 25 are connected in this order in the front-rear direction from the
front side of the upper body 20. The upper forefoot portion 23 is positioned in front
of the first boundary line S1. The upper midfoot portion 24 is positioned between
the first boundary line S1 and the second boundary line S2. The upper rearfoot portion
25 is positioned behind the second boundary line S2. The upper sole portion 26 is
connected to a lateral -foot-side lower edge of the upper midfoot portion 24. The
upper sole portion 26 serves as an inner sole that covers a lower opening disposed
by being surrounded by a lower edge of the upper forefoot portion 23, a lower edge
of the upper midfoot portion 24, and a lower edge of the upper rearfoot portion 25.
The upper sole portion 26 is fixed to the upper surface of the midsole 31 illustrated
in FIG. 2 by bonding or welding. Note that the shoe 1 may include an insole. If the
shoe 1 includes an insole, the insole is installed on the upper sole portion 26 inside
the upper 2.
[0024] The upper body 20 is disposed with the opening region 4 in which the first members
5 are disposed, and a joint region 6 to which the first members 5 are fixed. The opening
region 4 is a region other than the throat portion 20b and the foot insertion opening
20a in the region opening to the upper body 20. The opening region 4 is disposed over
the upper forefoot portion 23, the upper midfoot portion 24, the upper rearfoot portion
25, and the upper sole portion 26. The opening region 4 is disposed in a portion of
the upper body 20 other than the edge of the throat portion 20b, the edge of the foot
insertion opening 20a, the lower edge of the upper forefoot portion 23, the lower
edge of the upper midfoot portion 24 and the outer edge of the upper sole portion
26 excluding the boundary between the upper midfoot portion 24 and the upper sole
portion 26, the lower edge of the upper rearfoot portion 25, and the end edge on the
heel side.
[0025] The joint region 6 is a planar region disposed around the opening region 4. In other
words, the opening region 4 is disposed in the region surrounded by the joint region
6. The structure of the joint region 6 is not particularly limited as long as the
joint region 6 has higher stiffness than the opening region 4 in which the first members
5 are disposed. As the material of the joint region 6, for example, films, fibers,
resins, and composites of fibers and resins, or the like is used. Fibers, resins,
and composites of fibers and resins are joined by knitting, weaving, braiding, welding,
bonding, or the like. The joint region 6 is disposed along the outline of the upper
body 20 in the developed state.
[0026] The joint region 6 includes a first joint region 61 disposed at the lateral-foot-side
lower edges of the upper forefoot portion 23, the upper midfoot portion 24, and the
upper rearfoot portion 25, a second joint region 62 disposed at the medial-foot-side
lower edges of the upper forefoot portion 23, the upper midfoot portion 24, and the
upper rearfoot portion 25, and a third joint region 63 disposed at the heel-side end
edge of the upper rearfoot portion 25. The joint region 6 further includes a fourth
joint region 64 disposed at the front-side edge of the throat portion 20b, a fifth
joint region 65 disposed at the lateral-foot-side edges of the throat portion 20b
and the foot insertion opening 20a, and a sixth joint region 66 disposed at the medial-foot-side
edges of the throat portion 20b and the foot insertion opening 20a. The joint region
6 further includes a seventh joint region 67 disposed at the lateral-foot-side edge
of the upper sole portion 26, an eighth joint region 68 disposed at the medial-foot-side
edge of the upper sole portion 26, and a ninth joint region 69 disposed at the heel-side
end edge of the upper sole portion 26.
[0027] The first joint region 61 is not disposed in a part of the boundary between the upper
midfoot portion 24 and the upper sole portion 26. The first joint region 61 and the
second joint region 62 extend to be closer to a shoe center axis C from the rear side
toward the front side. The front ends of the first joint region 61 and the second
joint region 62 are connected to each other. The rear end of the first joint region
61 and the rear end of the second joint region 62 are connected to the lower end of
the third joint region 63. The fifth joint region 65 and the sixth joint region 66
extend forward from the upper end of the third joint region 63 toward the fourth joint
region 64. The front ends of the seventh joint region 67 and the eighth joint region
68 are connected to each other. The rear end of the seventh joint region 67 is connected
to the first joint region 61. The lateral-foot-side end of the ninth joint region
69 is connected to the first joint region 61.
[0028] The first members 5 are linear members extending to cross the opening region 4 in
the right-left direction or the height direction. The first members 5 are disposed
with a space from each other in the front-rear direction. The first members 5 are
disposed of a single material. Each of the first members 5 is, for example, a fiber,
a thread obtained by bundling a plurality of fibers, or a resin disposed into a linear
shape, and has flexibility. The first members 5 have elasticity in only one direction.
The first members 5 are disposed on the upper forefoot portion 23, the upper midfoot
portion 24, the upper rearfoot portion 25, and the upper sole portion 26. The first
members 5 on the upper forefoot portion 23 extend in the right-left direction between
the first joint region 61 and the second joint region 62. The first members 5 positioned
on the lateral foot side of the upper midfoot portion 24 extend from the fifth joint
region 65 to the eighth joint region 68 through the boundary between the upper midfoot
portion 24 and the upper sole portion 26. The first members 5 positioned on the medial
foot side of the upper midfoot portion 24 extend in the height direction between the
sixth joint region 66 and the second joint region 62. The first members 5 positioned
on the lateral foot side of the upper rearfoot portion 25 extend in the height direction
between the fifth joint region 65 and the first joint region 61. The first members
5 positioned on the medial foot side of the upper rearfoot portion 25 extend in the
height direction between the sixth joint region 66 and the second joint region 62.
The first members 5 positioned on the upper sole portion 26 extend in the right-left
direction between the seventh joint region 67 and the eighth joint region 68, or extend
in the right-left direction between the boundary between the upper midfoot portion
24 and the upper sole portion 26 and the eighth joint region 68.
[0029] Both ends of each of the first members 5 are fixed ends 50 fixed to the joint region
6 of the upper body 20 adjacent to the opening region 4. Hereinafter, when the fixed
ends 50 at both ends of the first members 5 are distinguished, the fixed ends 50 on
one end side of the first members 5 are referred to as fixed ends 51, and the fixed
ends 50 on the other end side of the first members 5 are referred to as fixed ends
52. The fixed ends 51 on the one end side of the first members 5 are arranged in the
front-rear direction. The fixed ends 52 on the other end side of the first members
5 are arranged in the front-rear direction. The order in which the fixed ends 51 on
the one end side of the first members 5 are arranged is equal to the order in which
the fixed ends 52 on the other end side of the first members 5 are arranged. The space
between adjacent fixed ends 50 in the front-rear direction on the one end side may
be different from that on the other end side, but the space on the one end side is
the same as that on the other end side in the present embodiment. The first members
5 are disposed in parallel to each other. Note that the shoelace 22 is passed through
a gap disposed between adjacent first members 5 and hooked to one of the first members
5.
[0030] Next, an effect of the upper 2 according to the present embodiment is described.
[0031] In the present embodiment, the upper 2 includes the upper body 20 that covers the
instep of a foot as illustrated in FIG. 1, and at least a part of the upper body 20
is the opening region 4 disposed with an opening as illustrated in FIG. 3. In the
opening region 4, the first members 5 extending in one direction are disposed in a
state of not being coupled with each other. Both ends of the first members 5 are the
fixed ends 50 fixed to the joint region 6 of the upper body 20 adjacent to the opening
region 4, and the order in which the fixed ends 51 on the one end side of the first
members 5 are arranged is equal to the order in which the fixed ends 52 on the other
end side of the first members 5 are arranged. With these structures, since the stiffness
of the opening region 4 in which the first members 5 are disposed is lower than that
of the joint region 6 adjacent to the opening region 4, it is possible to locally
reduce the stiffness of the upper body 20.
[0032] When the upper rearfoot portion 25 is contacted the ground while the upper forefoot
portion 23 illustrated in FIG. 3 is in contact with the ground, the forefoot of a
foot bends, which generates a bending point in the upper forefoot portion 23. In the
present embodiment, since the first members 5 are disposed on the upper forefoot portion
23 where the bending point is generated, it is possible to reduce the bending stiffness
of the portion where the bending point is generated in the upper forefoot portion
23. Accordingly, it is possible to reduce bending resistance of the upper body 20
during bending of a foot. In addition, since the first members 5 are easily deformed
following the bending of the foot, it is possible to ease the contact of the upper
body 20 with the foot and reduce fatigue failure of the materials of the upper body
20. By reducing the fatigue failure of the materials of the upper body 20, the strength
required for the materials of the upper body 20 can be reduced, and it is possible
to lead to weight reduction of the shoe 1.
[0033] In the present embodiment, since the first members 5 are disposed at a part of a
foot where the curvature in multiple directions is large as illustrated in FIG. 3,
it is possible to make the upper body 20 fit the foot well.
[0034] During movement, the skin of the midfoot of a foot mainly shrinks, twists, or distorts,
and the upper midfoot portion 24 illustrated in FIG. 3 is sheared and deformed. In
the present embodiment, since the first members 5 are disposed on the upper midfoot
portion 24, it is possible to reduce the stiffness of the upper midfoot portion 24.
Accordingly, the first members 5 are easily deformed following the strain of the skin
of the foot, and it is possible to reduce wrinkles generated in the upper body 20
and fatigue failure of the materials of the upper body 20. By reducing the fatigue
failure of the materials of the upper body 20, the strength required for the materials
of the upper body 20 can be reduced, and it is possible to lead to weight reduction
of the shoe 1.
[0035] In the present embodiment, by hooking the shoelace 22 to the first members 5 as illustrated
in FIG. 3, the first members 5 serve as a substitute for eyelets, and the eyelets
do not need to be disposed separately. In addition, by hooking the shoelace 22 to
some of the first members 5, a tightening force generated by tensioning the shoelace
is applied to some of the first members 5, and it is possible to locally tighten the
upper body 20.
[0036] In the present embodiment, as illustrated in FIG. 3, since the first members 5 extending
in one direction are disposed in the opening region 4 in a state of not being coupled
with each other, it is possible to improve air permeability between the inside and
the outside of the upper body 20 and to reduce the weight of the shoe 1.
[0037] In the present embodiment, the space between the adjacent fixed ends 50 on the one
end side is the same as that on the other end side, and this makes it difficult for
the first members 5 to intersect with each other. Accordingly, the first members 5
are easily sheared and deformed, and the first members 5 are more easily deformed
following the strain of the skin of the foot during movement.
[0038] In the present embodiment, since the first members 5 illustrated in FIG. 3 are disposed
of a single material, it is possible to easily manufacture the upper body 20 including
the first members 5.
(Second embodiment)
[0039] FIG. 4 is a plan view of a shoe 1A according to a second embodiment of the present
invention. FIG. 5 is a side view of the shoe 1A on a lateral foot side according to
the second embodiment. FIG. 6 is a developed view of an upper 2A according to the
second embodiment. The upper 2A according to the second embodiment is different from
the upper 2 according to the first embodiment in that the upper 2A has a monosock
structure and that the ranges of an opening region 4A and first members 5A. In the
second embodiment, portions that overlap with the first embodiment described above
are denoted by the same reference signs, and the descriptions thereof are omitted.
[0040] As illustrated in FIGS. 4 and 5, the upper 2A has a monosock structure in which a
portion corresponding to the shoe tongue 21 in the first embodiment is integrated
with an ankle portion of an upper body 20A. As illustrated in FIG. 6, a part of a
joint region 6A is disposed in front of a foot insertion opening 20a of the upper
body 20A. Hereinafter, this part of the joint region 6A is referred to as a center
joint region 6B. In the present embodiment, the opening region 4A is disposed over
an upper forefoot portion 23, an upper midfoot portion 24, and an upper sole portion
26. The opening region 4A is disposed from the front edge of the center joint region
6B to the vicinity of the center portion of the upper forefoot portion 23 in the front-rear
direction. In addition, the opening region 4A is disposed from the lateral-foot-side
edge of the center joint region 6B to the vicinity of the lateral-foot-side lower
edge of the upper forefoot portion 23 and the midfoot portion of the upper sole portion
26. The opening region 4A is further disposed from the medial-foot-side edge of the
center joint region 6B to the vicinity of the medial-foot-side lower edges of the
upper forefoot portion 23 and the upper midfoot portion 24.
[0041] In the opening region 4A, a plurality of first members 5A extending in one direction
is disposed in a state of not being coupled with each other. The first members 5A
are disposed on the upper forefoot portion 23, the upper midfoot portion 24, and the
upper sole portion 26. The first members 5A are bridged in portions of the joint region
6A that are positioned across the opening region 4A. With the present embodiment,
it is also possible to achieve an effect similar to that of the first embodiment described
above.
(Third embodiment)
[0042] FIG. 7 is a plan view of a shoe 1B according to a third embodiment of the present
invention. FIG. 8 is a side view of the shoe 1B on a lateral foot side according to
the third embodiment. An upper 2B according to the third embodiment is different from
the upper 2 according to the first embodiment in the ranges of an opening region 4B
and first members 5B. In the third embodiment, portions that overlap with the first
embodiment described above are denoted by the same reference signs, and the descriptions
thereof are omitted.
[0043] As illustrated in FIGS. 7 and 8, the opening region 4B is disposed in an upper midfoot
portion 24 in the present embodiment. The opening region 4B is disposed on each of
the lateral foot side and the medial foot side of a throat portion 20b. The opening
region 4B is disposed from the vicinity of the lateral-foot-side edge of the throat
portion 20b to the vicinity of the lateral-foot-side lower edge of the upper midfoot
portion 24. The opening region 4B is disposed from the vicinity of the medial-foot-side
edge of the throat portion 20b to the vicinity of the medial-foot-side lower edge
of the upper midfoot portion 24. The first members 5B are disposed on the upper midfoot
portion 24. As illustrated in FIG. 8, the first members 5B extend from the lateral-foot-side
edge or the medial-foot-side edge of the throat portion 20b toward a sole 3. The lower
ends of the first members 5B reach the vicinity of the lower edge of the upper midfoot
portion 24. The extending direction of the first members 5B is inclined to be positioned
rearward from the edge of the throat portion 20b toward the sole 3.
[0044] With the present embodiment, it is also possible to achieve an effect substantially
similar to that of the first embodiment described above. That is, in the present embodiment,
since the first members 5B are disposed on the upper midfoot portion 24, which causes
the first members 5B to be easily deformed following the strain of the skin of a foot,
it is possible to reduce wrinkles generated in the upper body 20B and fatigue failure
of the materials of the upper body 20B. By reducing the fatigue failure of the materials
of the upper body 20B, the strength required for the materials of the upper body 20B
can be reduced, and it is possible to lead to weight reduction of the shoe 1B. In
the present embodiment, by hooking a shoelace 22 to the first members 5B, the first
members 5B serve as a substitute for eyelets, and the eyelets do not need to be disposed
separately. Since the shoelace 22 is hooked on some of the first members 5B, a tightening
force generated by tensioning the shoelace is applied to some of the first members
5B, and it is possible to locally tighten the upper body 20B. In the present embodiment,
since the first members 5B extending in one direction are disposed in the opening
region 4B in a state of not being coupled with each other, it is possible to improve
air permeability between the inside and the outside of the upper body 20B and to reduce
the weight of the shoe 1B.
(Fourth embodiment)
[0045] FIG. 9 is a plan view of a shoe 1C according to a fourth embodiment of the present
invention. FIG. 10 is a side view of the shoe 1C on a lateral foot side according
to the fourth embodiment. An upper 2C according to the fourth embodiment is different
from the upper 2 according to the first embodiment in the ranges of an opening region
4C and first members 5C and in that an upper body 20C is disposed with a string passing
portion 27. In the fourth embodiment, portions that overlap with the first embodiment
described above are denoted by the same reference signs, and the descriptions thereof
are omitted.
[0046] As illustrated in FIGS. 9 and 10, the opening region 4C is disposed in an upper forefoot
portion 23 in the present embodiment. The opening region 4C is disposed from the lateral-foot-side
lower edge of the upper forefoot portion 23 through the front of a throat portion
20b to the medial-foot-side lower edge of the upper forefoot portion 23. The first
members 5C are disposed on the upper forefoot portion 23 and extend in the right-left
direction. The lateral-foot-side ends of the first members 5C reach the lateral-foot-side
lower edge of the upper forefoot portion 23. The medial-foot-side ends of the first
members 5C reach the medial-foot-side lower edge of the upper forefoot portion 23.
As illustrated in FIG. 10, the extending direction of the first members 5C is inclined
to be positioned rearward from the shoe center axis toward the lower edge of the upper
forefoot portion 23. As illustrated in FIG. 9, on both edges of the throat portion
20b in the right-left direction, a plurality of string passing portions 27 spaced
apart from each other in the front-rear direction is disposed. The structure of the
string passing portions 27 is not particularly limited as long as a shoelace 22 can
be passed therethrough, but in the present embodiment, the string passing portions
27 are through holes that pass through the upper body 20C in the vertical direction.
[0047] With the present embodiment, it is also possible to achieve an effect substantially
similar to that of the first embodiment described above. That is, in the present embodiment,
since the first members 5C are disposed on the upper forefoot portion 23 where a bending
point is generated, which causes the first members 5C to be easily deformed following
the bending of a foot, it is possible to ease the contact of the upper body 20C with
the foot and reduce fatigue failure of the materials of the upper body 20C. By reducing
the fatigue failure of the materials of the upper body 20C, the strength required
for the materials of the upper body 20C can be reduced, and it is possible to lead
to weight reduction of the shoe 1C. In the present embodiment, since the first members
5C extending in one direction are disposed in the opening region 4C in a state of
not being coupled with each other, it is possible to improve air permeability between
the inside and the outside of the upper body 20C and to reduce the weight of the shoe
1C.
(Fifth embodiment)
[0048] FIG. 11 is a plan view of a shoe 1D according to a fifth embodiment of the present
invention. FIG. 12 is a side view of the shoe 1D on a lateral foot side according
to the fifth embodiment. An upper 2D according to the fifth embodiment is different
from the upper 2 according to the first embodiment in the ranges of an opening region
4D and first members 5D and in that an upper body 20D is disposed with a string passing
portion 27. In the fifth embodiment, portions that overlap with the first embodiment
described above are denoted by the same reference signs, and the descriptions thereof
are omitted.
[0049] As illustrated in FIGS. 11 and 12, the opening region 4D is disposed from an upper
midfoot portion 24 to an upper rearfoot portion 25 in the present embodiment. As illustrated
in FIG. 11, the opening region 4D is disposed from the lateral-foot-side edge of a
throat portion 20b through the heel-side end edge of the upper rearfoot portion 25
to the medial-foot-side edge of the throat portion 20b. The first members 5D are disposed
from the upper midfoot portion 24 to the upper rearfoot portion 25. The first members
5D extend from the lateral-foot-side edge of the throat portion 20b toward the upper
rearfoot portion 25, and then extend to the medial-foot-side edge of the throat portion
20b through the heel-side end edge of the upper rearfoot portion 25. The first members
5D extend to surround a foot insertion opening 20a. As illustrated in FIG. 12, the
extending direction of the first members 5D is inclined to be positioned downward
from the lateral-foot-side edge and the medial-foot-side edge of the throat portion
20b toward the upper rearfoot portion 25. As illustrated in FIG. 11, on both edges
of the throat portion 20b in the right-left direction, a plurality of string passing
portions 27 spaced apart from each other in the front-rear direction is disposed.
Each rear end of a shoelace 22 is hooked to the first members 5 and exposed to the
outside of the upper body 20D from a gap between adjacent first members 5.
[0050] With the present embodiment, it is also possible to achieve an effect substantially
similar to that of the first embodiment described above. That is, in the present embodiment,
by hooking the shoelace 22 to the first members 5D, the first members 5D serve as
a substitute for eyelets, and the eyelets do not need to be disposed separately. In
addition, by hooking the shoelace 22 to some of the first members 5D, a tightening
force generated by tensioning the shoelace 22 is applied to some of the first members
5D, and it is possible to locally tighten the upper body 20D. In particular, in the
present embodiment, since the first members 5D extend to surround the foot insertion
opening 20a, it is possible to locally tighten a portion around the foot insertion
opening 20a of the upper body 20D. In addition, in the present embodiment, since the
first members 5D extending in one direction are disposed in the opening region 4D
in a state of not being coupled with each other, it is possible to improve air permeability
between the inside and the outside of the upper body 20D and to reduce the weight
of the shoe 1D.
(Sixth embodiment)
[0051] FIG. 13 is a plan view of a shoe 1E according to a sixth embodiment of the present
invention and illustrates a state before a shoelace 22 is pulled. FIG. 14 is a side
view of the shoe 1E on a lateral foot side according to the sixth embodiment. FIG.
15 is a plan view of the shoe 1E according to the sixth embodiment of the present
invention and illustrates a state in which the shoelace 22 is pulled from the state
illustrated in FIG. 13. An upper 2E according to the sixth embodiment is different
from the upper 2 according to the first embodiment in the ranges and structures of
an opening region 4E and first members 5E. In the sixth embodiment, portions that
overlap with the first embodiment described above are denoted by the same reference
signs, and the descriptions thereof are omitted. In FIGS. 13 to 15, for ease of understanding,
the opening region 4E is illustrated with dot hatching, and the first members 5E are
omitted in FIGS. 13 and 15.
[0052] As illustrated in FIGS. 13 and 14, the opening region 4E is disposed in an upper
midfoot portion 24 in the present embodiment. The opening region 4E is adjacent to
the lateral-foot-side edge of a throat portion 20b, and is disposed from the lateral-foot-side
edge of the throat portion 20b to the vicinity of the lateral-foot-side lower edge
of the upper midfoot portion 24. The opening region 4E is adjacent to the medial-foot-side
edge of the throat portion 20b, and is disposed from the medial-foot-side edge of
the throat portion 20b to the vicinity of the medial-foot-side lower edge of the upper
midfoot portion 24. As illustrated in FIG. 14, the first members 5E are disposed on
the upper midfoot portion 24. The first members 5E extend from the lateral-foot-side
edge of the throat portion 20b toward a sole 3 in the opening region 4E on the lateral
foot side. The lateral-foot-side lower ends of the first members 5E reach the vicinity
of the lower edge of the upper midfoot portion 24. Although not illustrated, the first
members 5E similarly extend from the medial-foot-side edge of the throat portion 20b
toward the sole 3 in the opening region 4E on the medial foot side. The medial-foot-side
lower ends of the first members 5 reach the vicinity of the lower edge of the upper
midfoot portion 24. The extending direction of the first members 5E is inclined to
be positioned rearward from the lateral-foot-side edge and the medial-foot-side edge
of the throat portion 20b toward the sole 3.
[0053] The first members 5E include a first extendable member 53 and a second extendable
member 54 having higher extensibility in one direction than the first extendable member
53. The opening region 4E includes a first region 41 in which a plurality of first
extendable members 53 is arranged in the front-rear direction, and a second region
42 in which a plurality of second extendable members 54 is arranged in the front-rear
direction. The first region 41 and the second region 42 are alternately disposed in
the front-rear direction on the lateral foot side and the medial foot side of the
throat portion 20b. In FIGS. 13 to 15, the first regions 41 and the second regions
42 are distinguished from each other by shading of dot hatching.
[0054] As illustrated in FIG. 13, the upper 2E includes a front edge portion 20c, a first
side edge portion 20d, a second side edge portion 20e, a plurality of first disposed
portions 20f, a plurality of second disposed portions 20g, and a plurality of string
passing portions 27. Hereinafter, when the string passing portions 27 are distinguished,
they are referred to as a lateral-foot-side string passing portion 27a, a medial-foot-side
string passing portion 27b, a toe-side string passing portion 27c, and a heel-side
string passing portion 27d. The lateral-foot-side string passing portion 27a, the
medial-foot-side string passing portion 27b, the toe-side string passing portion 27c,
and the heel-side string passing portion 27d are actually gaps disposed between adjacent
first members 5E, but in FIGS. 13 to 15, the string passing portions 27 are illustrated
as circular holes for ease of understanding.
[0055] The front edge portion 20c is the front-side edge of the throat portion 20b. The
front edge portion 20c extends in the right-left direction. The first side edge portion
20d is the lateral-foot-side edge of the throat portion 20b. The second side edge
portion 20e is the medial-foot-side edge of the throat portion 20b. The first side
edge portion 20d and the second side edge portion 20e extend in the front-rear direction.
[0056] Each first disposed portion 20f is a part of the second region 42 and protrudes from
the first side edge portion 20d toward the second side edge portion 20e. The shape
of each first disposed portion 20f in plan view is not particularly limited, but is
a rectangle with rounded corners in the present embodiment. The shape of each first
disposed portion 20f in plan view may be a polygon or a semicircle. The number of
the first disposed portions 20f is not particularly limited, but is two in the present
embodiment. The two first disposed portions 20f are spaced apart from each other in
the front-rear direction. Note that each first disposed portion 20f may be a part
of one of the first region 41 and the second region 42.
[0057] Each second disposed portion 20g is a part of the second region 42 and protrudes
from the second side edge portion 20e toward the first side edge portion 20d. The
shape of each second disposed portion 20g in plan view is not particularly limited,
but is a rectangle with rounded corners in the present embodiment. The shape of each
second disposed portion 20g in plan view may be a polygon or a semicircle. The number
of the second disposed portions 20g is not particularly limited, but is two in the
present embodiment. The two second disposed portions 20g are spaced apart from each
other in the front-rear direction. The first disposed portion 20f and the second disposed
portion 20g are alternately disposed in the front-rear direction. In the present embodiment,
the second disposed portion 20g and the first disposed portion 20f are alternately
disposed from the front side to the rear side in this order. Note that each second
disposed portion 20g may be a part of one of the first region 41 and the second region
42.
[0058] One toe-side string passing portion 27c is disposed on the lateral foot side of the
throat portion 20b. The toe-side string passing portion 27c is disposed in front of
the lateral-foot-side string passing portion 27a. The toe-side string passing portion
27c is disposed in the vicinity of the boundary between the first side edge portion
20d and the front edge portion 20c.
[0059] The lateral-foot-side string passing portion 27a is constituted by a pair of one
first string passing portion 27e disposed in the first disposed portion 20f and one
second string passing portion 27f spaced apart on the lateral foot side from the first
string passing portion 27e. The first string passing portion 27e is disposed in the
second region 42. The second string passing portion 27f is disposed in the first region
41. The number of pairs of lateral-foot-side string passing portions 27a is not particularly
limited, but is two in the present embodiment. The two pairs of lateral-foot-side
string passing portions 27a are spaced apart from each other in the front-rear direction.
The first string passing portion 27e and the second string passing portion 27f are
disposed to be shifted in the front-rear direction and the right-left direction. In
a pair of lateral-foot-side string passing portions 27a, the second string passing
portion 27f is spaced apart on the lateral foot side and the rear side from the first
string passing portion 27e. The second string passing portion 27f is positioned closer
to the lateral foot side than the first side edge portion 20d. Note that each lateral-foot-side
string passing portions 27a may be disposed in at least one of the first region 41
and the second region 42.
[0060] The medial-foot-side string passing portion 27b is constituted by a pair of one third
string passing portion 27g disposed in the second disposed portion 20g and one fourth
string passing portion 27h spaced apart on the medial foot side from the third string
passing portion 27g. The third string passing portion 27g is disposed in the second
region 42. The fourth string passing portion 27h is disposed in the first region 41.
The number of pairs of medial-foot-side string passing portions 27b is not particularly
limited, but is two in the present embodiment. The two pairs of medial-foot-side string
passing portions 27b are spaced apart from each other in the front-rear direction.
The third string passing portion 27g and the fourth string passing portion 27h are
disposed to be shifted in the right-left direction and the front-rear direction. In
a pair of medial-foot-side string passing portions 27b, the fourth string passing
portion 27h is spaced apart on the medial foot side and the front side from the third
string passing portion 27g. The fourth string passing portion 27h is positioned closer
to the medial foot side than the second side edge portion 20e. The fourth string passing
portion 27h, which is positioned at the foremost side among the two pairs of medial-foot-side
string passing portions 27b, is disposed at a position right-left symmetrical to the
toe-side string passing portion 27c across the throat portion 20b. In the present
embodiment, the first string passing portion 27e is spaced apart on the lateral foot
side and the rear side from the third string passing portion 27g, but the first string
passing portion 27e and the third string passing portion 27g may be disposed side
by side in the front-rear direction. Note that each medial-foot-side string passing
portion 27b may be disposed in at least one of the first region 41 and the second
region 42.
[0061] The heel-side string passing portion 27d is disposed behind the lateral-foot-side
string passing portions 27a and the medial-foot-side string passing portions 27b.
In the present embodiment, there are two heel-side string passing portions 27d; one
is disposed on the lateral foot side of the throat portion 20b, and the other is disposed
on the medial foot side. The two heel-side string passing portions 27d are disposed
at right-left symmetrical positions across the throat portion 20b. The heel-side string
passing portions 27d are disposed in the vicinity of the boundary between the edge
of the throat portion 20b and the edge of the foot insertion opening 20a.
[0062] The shoelace 22 is passed through the toe-side string passing portion 27c, the lateral-foot-side
string passing portions 27a, the medial-foot-side string passing portions 27b, and
the heel-side string passing portions 27d. Although not illustrated, both ends of
the shoelace 22 in the length direction are tied together with a bow knot or the like.
The shoelace 22 includes a first portion 22a alternately passed through the second
string passing portion 27f and the third string passing portion 27g, a second portion
22b alternately passed through the first string passing portion 27e and the fourth
string passing portion 27h, and a third portion 22c extending between the toe-side
string passing portion 27c and the fourth string passing portion 27h positioned at
the foremost position and connecting the first portion 22a and the second portion
22b. The third portion 22c extends in the right-left direction across the throat portion
20b.
[0063] The first portion 22a extends obliquely rearward from the toe-side string passing
portion 27c, is alternately passed through the third string passing portion 27g and
the second string passing portion 27f, and is then passed through the heel-side string
passing portion 27d on the lateral foot side. In a state before the shoelace 22 is
pulled as illustrated in FIG. 13, the second string passing portion 27f and the third
string passing portion 27g are disposed to be shifted in the front-rear direction
and the right-left direction. Therefore, the first portion 22a alternately passed
through the second string passing portion 27f and the third string passing portion
27g extends in a zigzag shape in the right-left direction from the front side toward
the rear side.
[0064] The second portion 22b extends obliquely rearward from the fourth string passing
portion 27h positioned at the foremost position, is alternately passed through the
first string passing portion 27e and the fourth string passing portion 27h, and is
then passed through the heel-side string passing portion 27d on the medial foot side.
In a state before the shoelace 22 is pulled, the first string passing portion 27e
and the fourth string passing portion 27h are disposed to be shifted in the front-rear
direction and the right-left direction. Therefore, the second portion 22b alternately
passed through the first string passing portion 27e and the fourth string passing
portion 27h extends in a zigzag shape in the right-left direction from the front side
to the rear side. In a state before the shoelace 22 is pulled, the first portion 22a
and the second portion 22b do not intersect with each other. In a state before the
shoelace 22 is pulled, a portion of the first portion 22a alternately passed through
the second string passing portion 27f and the third string passing portion 27g and
a portion of the second portion 22b alternately passed through the first string passing
portion 27e and the fourth string passing portion 27h are parallel to each other.
[0065] As illustrated in FIG. 15, by pulling the first portion 22a and the second portion
22b toward the rear side from the state illustrated in FIG. 13, the first side edge
portion 20d and the second side edge portion 20e of the upper body 20E are pulled
together. Accordingly, the distance in the right-left direction between the second
string passing portion 27f and the third string passing portion 27g is reduced, and
the distance in the right-left direction between the first string passing portion
27e and the fourth string passing portion 27h is reduced. Therefore, the first portion
22a alternately passed through the second string passing portion 27f and the third
string passing portion 27g approaches a state of linearly extending in the front-rear
direction, and the second portion 22b alternately passed through the first string
passing portion 27e and the fourth string passing portion 27h approaches a state of
linearly extending in the front-rear direction. In a state in which the shoelace 22
passed through the lateral-foot-side string passing portions 27a and the medial-foot-side
string passing portions 27b is pulled, the first portion 22a and the second portion
22b do not intersect with each other. In a state in which the shoelace 22 passed through
the lateral-foot-side string passing portions 27a and the medial-foot-side string
passing portions 27b is pulled, a portion of the first portion 22a alternately passed
through the second string passing portion 27f and the third string passing portion
27g and a portion of the second portion 22b alternately passed through the first string
passing portion 27e and the fourth string passing portion 27h are parallel to each
other.
[0066] With the present embodiment, it is also possible to achieve an effect substantially
similar to that of the first embodiment described above. That is, in the present embodiment,
since the first members 5E extending in one direction are disposed in the opening
region 4E in a state of not being coupled with each other, it is possible to improve
air permeability between the inside and the outside of the upper body 20E and to reduce
the weight of the shoe 1E.
[0067] In the present embodiment, in a state in which the shoelace 22 is pulled as illustrated
in FIG. 15, the first portion 22a and the second portion 22b do not intersect with
each other over the instep of a foot. Therefore, as compared with a case where the
shoelace 22 intersects over the instep of a foot, the pressure on the instep of the
foot is reduced, and it is possible to reduce the tightening feeling on the instep
of the foot.
[0068] In the present embodiment, since the first region 41 in which the first extendable
members 53 are arranged and the second region 42 in which the second extendable members
54 are arranged are alternately disposed in the front-rear direction on the lateral
foot side and the medial foot side of the throat portion 20b as illustrated in FIG.
14, and the lateral-foot-side string passing portions 27a and the medial-foot-side
string passing portions 27b are disposed in the first region 41 and the second region
42 as illustrated in FIG. 15, the first side edge portion 20d and the second side
edge portion 20e are easily pulled together when the shoelace 22 is pulled. Accordingly,
it is possible to reliably bring the upper 2E into close contact with the foot.
[0069] In the present embodiment, as illustrated in FIG. 15, the lateral-foot-side string
passing portion 27a constituted by a pair of one first string passing portion 27e
and one second string passing portion 27f and the medial-foot-side string passing
portion 27b constituted by a pair of one third string passing portion 27g and one
fourth string passing portion 27h are alternately disposed in the front-rear direction.
That is, since there are two string passing portions 27 alternately disposed on each
of the lateral foot side and the medial foot side of the throat portion 20b, a force
for pulling the first side edge portion 20d and the second side edge portion 20e together
when the shoelace 22 is pulled is stronger than a case where one string passing portion
27 is alternately disposed on each of the lateral foot side and the medial foot side
of the throat portion 20b. Accordingly, it is possible to reliably bring the upper
2E into close contact with the foot.
(Seventh embodiment)
[0070] FIG. 16 is a schematic perspective view of a first member 5F according to a seventh
embodiment of the present invention. An upper 2F according to the seventh embodiment
is different from the upper 2 according to the first embodiment in the structure of
the first member 5F. In the seventh embodiment, portions that overlap with the first
embodiment described above are denoted by the same reference signs, and the descriptions
thereof are omitted.
[0071] The first member 5F is a flexible tubular tube. The first member 5F has a cylindrical
shape in the present embodiment, but may have a quadrangular cylindrical shape or
the like. With the present embodiment, it is possible to achieve an effect similar
to that of the first embodiment described above.
(Eighth embodiment)
[0072] FIG. 17 is a developed view of an upper 2G of a shoe according to an eighth embodiment
of the present invention. The upper 2G according to the eighth embodiment is different
from the upper 2 according to the first embodiment in that the upper 2G includes a
second member 7. In the eighth embodiment, portions that overlap with the first embodiment
described above are denoted by the same reference signs, and the descriptions thereof
are omitted.
[0073] In an opening region 4, a plurality of second members 7 extending in one direction
is disposed in a state of not being coupled with each other. The second members 7
are linear members extending to longitudinally cross the opening region 4 in the front-rear
direction. The second members 7 are disposed with a space from each other in the right-left
direction. The second members 7 are disposed of a single material. Each of the second
members 7 is, for example, a fiber, a thread obtained by bundling a plurality of fibers,
or a resin disposed into a linear shape, and has flexibility. The second members 7
have elasticity in only one direction. The second members 7 are disposed to overlap
with first members 5. The second members 7 extend in a direction intersecting with
the first members 5. The second members 7 are disposed over an upper forefoot portion
23, an upper midfoot portion 24, and an upper rearfoot portion 25. In each of the
upper forefoot portion 23, the upper midfoot portion 24, and the upper rearfoot portion
25, the number of the first members 5 is greater than the number of the second members
7. The first members 5 and the second members 7 are disposed in a state of not being
coupled with each other. The second members 7 may be disposed by combining a plurality
of materials.
[0074] The second members 7 are disposed on the lateral foot side and the medial foot side
of a throat portion 20b and a foot insertion opening 20a. The second members 7 on
the lateral foot side extend in the front-rear direction between a first joint region
61 and a third joint region 63 to longitudinally cross the upper forefoot portion
23, the upper midfoot portion 24, and the upper rearfoot portion 25. The second members
7 on the medial foot side extend in the front-rear direction between a second joint
region 62 and the third joint region 63 to longitudinally cross the upper forefoot
portion 23, the upper midfoot portion 24, and the upper rearfoot portion 25. Both
ends of each of the second members 7 are fixed ends 70 fixed to a joint region 6 of
an upper body 20G adjacent to the opening region 4. Hereinafter, when the fixed ends
70 at both ends of the second members 7 are distinguished, the fixed ends 70 on one
end side of the second members 7 are referred to as fixed ends 71, and the fixed ends
70 on the other end side of the second members 7 are referred to as fixed ends 72.
The fixed ends 71 on the one end side of the second members 7 are arranged in the
right-left direction. The fixed ends 72 on the other end side of the second members
7 are arranged in the right-left direction. The order in which the fixed ends 71 on
the one end side of the second members 7 are arranged is equal to the order in which
the fixed ends 72 on the other end side of the second members 7 are arranged. The
space between adjacent fixed ends 70 in the right-left direction on the one end side
may be different from that on the other end side, but the space on the one end side
is the same as that on the other end side in the present embodiment. The second members
7 are disposed in parallel to each other.
[0075] With the present embodiment, it is possible to achieve an effect similar to that
of the first embodiment described above. In addition, according to the present embodiment,
since the second members 7 extending in the direction intersecting with the first
members 5 are disposed in the opening region 4 in a state of not being coupled with
each other, it is possible to reduce the damage of the first members 5 and to increase
variations in the strength of stiffness of the upper body 20G, as compared with a
portion in which only the first members 5 are disposed in the opening region 4. In
addition, since the first members 5 and the second members 7 are disposed in a state
of not being coupled with each other and the number of the first members 5 is greater
than the number of the second members 7, it is possible to control the excessive increase
in the stiffness of the region where the second members 7 are disposed. The position
at which the second members 7 are disposed is not limited to the illustrated example,
and may be appropriately changed. In addition, the first members 5 and the second
members 7 are only required to intersect with each other. For example, the first members
5 may be disposed to extend in the front-rear direction, and the second members 7
may be disposed to extend in the right-left direction.
(Ninth embodiment)
[0076] FIG. 18 is a developed view of an upper 2H of a shoe according to a ninth embodiment
of the present invention. The upper 2H according to the ninth embodiment is different
from the upper 2 according to the first embodiment in that the upper 2H includes a
second member 8. In the ninth embodiment, portions that overlap with the first embodiment
described above are denoted by the same reference signs, and the descriptions thereof
are omitted.
[0077] In an opening region 4, a plurality of second members 8 disposed to overlap a plurality
of first members 5 is disposed. The second members 8 are flexible sheet-like members.
The second members 8 are disposed of a single material. The material of the second
members 8 is, for example, resin. The second members 8 are disposed on an upper midfoot
portion 24. The number of second members 8 is not particularly limited, but is two
in the present embodiment. One of the two second members 8 is disposed on the lateral
foot side of a throat portion 20b and a foot insertion opening 20a, and the other
is disposed on the medial foot side. The first members 5 and the second members 8
are disposed in a state of not being coupled with each other. The second members 8
are fixed to a joint region 6 adjacent to the opening region 4. The second members
8 may be disposed by combining a plurality of materials.
[0078] With the present embodiment, it is possible to achieve an effect similar to that
of the first embodiment described above. In addition, according to the present embodiment,
since the second members 8 disposed to overlap the first members 5 are disposed in
the opening region 4, it is possible to reduce the damage of the first members 5 and
to increase variations in the strength of stiffness of the upper body 20H, as compared
with a portion in which only the first members 5 are disposed in the opening region
4. In addition, since the first members 5 and the second members 8 are disposed in
a state of not being coupled with each other, it is possible to control the excessive
increase in the stiffness of the region where the second members 8 are disposed. The
position at which the second members 8 are disposed is not limited to the illustrated
example, and may be appropriately changed.
[0079] The configurations described in the above embodiments merely show examples of the
present invention and can be combined with another known technique, and a part of
each configuration can be omitted or changed without departing from the gist of the
present invention. The ranges of the opening regions 4 to 4E and the first members
5 to 5E are not limited to the examples illustrated in the above embodiments, and
may be appropriately changed according to portions of the upper bodies 20 to 20E where
stiffness is desired to be reduced.
[0080] The upper sole portion 26 may be omitted from each of the above embodiments. In each
of the above embodiments, the first members 5 to 5F are disposed of a single material,
but the first members 5 to 5F may be disposed by combining a plurality of materials.
In addition, the first members 5 to 5F may be disposed in contact with each other
or may be disposed with a space from each other as long as the first members 5 to
5F are disposed in a state of not being coupled with each other. Reference Signs List
