BACKGROUND OF THE DESCRIPTION
[0001] The present subject matter relates to a hip wing of a hip belt for a backpack and
a backpack.
[0002] Known hip belts comprise a belt having two opposite end portions and an attaching
portion arranged in-between of the end portions. Such a belt encircles a hip of a
user for load-distributing a load e.g. carried in a backpack.
[0003] The end portions are adapted such that the circumference of the belt can be adjusted
to different hips for different users. Usually, the end portions comprise a buckle
or other means for securing the end portions to each other. The attaching portion
is adapted for detachably mounting the hip belt to a backpack.
[0004] Further, another commonly known hip belt comprises an attaching portion and two opposite
hip wings for enclosing a hip of a user. Each hip wing comprises two ends, wherein
a first end is affixed to the attaching portion and a second end comprises an end
portion which is adapted such that the belt's circumference can be adjusted to the
hip of different users as already mentioned. The end portions comprise a strap buckle
assembly or other means for securing the end portions to each other so that the length
of the hip wing enclosing a user's hip is adjustable to the personal conditions of
the user.
[0005] Thus, on one end portion normally a free end of a strap is positioned, wherein on
the other end portion a buckle having a maze is positioned. The free end is guided
through the maze forming a pathway which guides the strap. The pathway and the maze,
respectively, is normally formed by two bars of the buckle displaced to each other
such that between strap and bars a high friction force is produced.
[0006] For adjusting the length of the strap, the distance of the two end portions of the
two ends of the hip wing relative to each other is increased or decreased. This is
done by adapting the length between the two end portions of the belt.
[0007] Further, each hip wing comprises a greater width in comparison to the strap so that
a high surface area of the hip wing contacts the hip and the hip bone of a user, respectively.
The broadened hip wings get in contact on the left and on the right of a user's hip
so that the above mentioned surface area forms a part and a prolongation of the hip
and the hip bone, respectively. Thus, a part of the surface area sits on the user's
hip bone. By this, a load e.g. carried in a backpack can be load-distributed to a
hip of a user.
[0008] Due to the fact that the length of the hip wings are predetermined and due to the
fact that each user of a hip belt has a different anatomy, especially with regard
to the hip bone, commonly known hip belts cannot be fitted exactly to each user's
needs. This is because, for instance, women comprises another hip anatomy in comparison
to men, wherein men need usually a greater length of the hip wing and the hip belt,
respectively, to fit and load-distribute optimally to the respective hip. Thus, different
hip belts for different anatomies have to be produced increasing production costs.
[0009] Further, as a hip belt and its hip wing, respectively, e.g. encircles optimally the
hip of a first person, the same belt can only encircle a part of hip of a second person.
This is because e.g. in the first situation the hip belt and its hip wing fit to the
hip bone of the first person, wherein in the second situation the belt and the wing,
respectively, does not fit to the hip bone of the second person.
[0010] Even further, during use of a commonly known hip belt with hip wings some users receive
pain from the load carried in a backpack when the load is supported by a hip wing
to a user's hip. Thus, the user gets an inconvenient feeling of carrying such a backpack
with such a hip wing, wherein such a hip wing causes pain and limits the time for
wearing, in particular, limits the time for carrying a backpack.
SUMMARY
[0011] The present subject matter relates to a hip wing of a hip belt for a backpack and
a backpack.
[0012] According to a first aspect of the subject matter, a hip wing of a hip belt for a
backpack comprises a size adjusting part and a reinforcing part adjustable to each
other. Thus, the relative position of both can be freely adjusted. Further, the reinforcing
part comprises preferably at least one contact means, wherein the size adjusting part
comprises at least two receiving means. It is also possible that the size adjusting
part comprises at least one receiving means. Advantageously, an adjusting of both
the at least one contact means and the at least one or two receiving means is realizable.
[0013] Preferably, the at least one contact means is arranged for modifiably adjusting the
position of the reinforcing part in relation to the size adjusting part by selectively
engaging the at least one contact means with one of the at least two receiving means.
Advantageously, a selectively engaging of the at least one contact means can also
be possible with the at least one receiving means. Thus, it is also preferred that
the at least one contact means is arranged for modifiably adjusting the position of
the reinforcing part in relation to the size adjusting part by engaging the at least
one contact means with the at least one receiving means.
[0014] This adjusting allows the relative positioning of the size adjusting part and the
reinforcing part to each other in relative positions. These relative positions are
realized by engaging of the at least one contact means with the at least one or two
receiving means. Preferably, in case of only at least one receiving means the receiving
means as well as the at least one contact means are adapted to engage each other in
any freely chosen relative position to each other. This means that preferably the
at least one receiving means comprises e.g. a rail in which the at least one contact
means can engage. This can be realized by using a dovetail groove, for instance. Using
such a rail and a groove, respectively, the relative position of the reinforcing part
and the size adjusting part to each other can be arbitrarily adjusted.
[0015] In another case, in which for example at least two receiving means are used, the
sized adjusting part preferably comprises predetermined positions. In these positions
an engaging of the at least one contact means of the receiving part can engage. Thus,
relative positions for the reinforcing part in relation to the size adjusting part
can be predetermined.
[0016] In other words, if using at least one receiving means of a size adjusting part the
at least one contact means of the reinforcing part is arranged for modifiably adjusting
the position of the reinforcing part in relation to the size adjusting part in any
desired position to each other. Further, in case of using at least two receiving means
the relative position of the at least one contact means of the reinforcing part is
arranged for modifiably adjusting the position of the reinforcing part in relation
to the size adjusting part in predetermined position to each other.
[0017] Thus, by choosing a system of engagement of the size adjusting part with the reinforcing
part the variability of a hip wing of a hip belt for a backpack can be increased by
the adaption of the relative position of the reinforcing part to size adjusting part
in either predetermined positions or in any desired position.
[0018] Hence, the size and the length, respectively, of a hip wing of a hip belt is modifiably
adjustable. Further, the hip wing of the hip belt can be positioned such to a user's
hip and hip bone, respectively, that the hip wing is optimally fitted on and to the
hip bones of a user. This allows an optimal load distribution to the user's hip.
[0019] According to an embodiment of the present subject matter, the at least one contact
means is formed by a section of the reinforcing part. Preferably, the reinforcing
part has two sections, wherein in particular the second section comprises at least
one contact means, and wherein typically the first section comprises means for mounting.
Thus, using the means for mounting and mounting means, respectively, the reinforcing
part of the hip wing can be mounted to another element, member or part of the hip
belt or a backpack.
[0020] According to an embodiment of the present subject matter, the at least one receiving
means or the at least two receiving means comprises a socket. Such a socket provides
an easy, cost effective and low maintenance realization of a member adapted for connecting
to another element of the hip wing.
[0021] According to an embodiment of the present subject matter, the at least one contact
means of the reinforcing part comprises a first end and a second end which are adjacent
to each other. Advantageously, the first end and the second end comprise each at least
one surface facing to each other. Preferably, the first and the second end of the
reinforcing part are springingly, flexible or elastic mounted such that a force pushes
the two ends together. In particular, the at least one surface of the first end and
the at least one surface of the second end are subjected to a force pushing the at
least one surface of the first end into the direction of the at least one surface
of the second end.
[0022] In this context, it is preferred that the reinforcing part is formed in a loop-shape,
in particular in a sigma shape. Moreover, preferably the reinforcing part comprises
a flexible wire, in particular made of metal, spring steel and/or a cylindrical piece
of steel. Under the preferred precondition that the reinforcing part is formed in
a loop-shape having a recess, wherein the recess preferably forms the first and second
end, it is possible that the section having the recess and the two ends, respectively,
is the second section of the reinforcing part and the section opposite to the recess
and the first and second end, respectively, typically is the first section of the
reinforcing part.
[0023] By forming a loop-shape an easy and cost effective way of building a spring force
is realizable. Thus, the first and second end of a loop-shaped reinforcing part can
be easily pushed together such that the spring force tries to close the recess in
the loop-shaped reinforcing part.
[0024] A loop can comprise a shape and a loop-shape, respectively, similar to a rectangle,
wherein the rectangle comprises a recess for realizing a first and a second end being
adjacent to each other.
[0025] Preferably, the reinforcing part comprises a sigma shape, in particular a shape similar
to a sigma. This shape is similar to a loop, wherein the special form of the sigma
forms a first section and a second section. It is preferred that the second section
has a first and a second end which are adjacent to each other. Further, it is preferred
that the first section in which the sigma comprises its special sigma form a mounting
of the reinforcing part and of the first section, respectively, can be easily realized.
Thus, a mounting of the reinforcing part is possible to a further member. The advantage
of the sigma-shape in particular of its closed area opposite to the open ends is that
a vertical translational movement of such a sigma-shaped reinforcing part can be restricted.
[0026] According to an embodiment of the present subject matter, the reinforcing part comprises
two sections positioned adjacent to each other. Preferably, in the first section the
reinforcing part is pivotably arrangeable. Thus, by engaging the at least one contact
means of the reinforcing part with the at least one/two receiving means of the size
adjusting part for example the reinforcing part is able to pivot about the size adjusting
part and vice versa.
[0027] Advantageously, in the second section the at least one contact means of the reinforcing
part is engageable with the adjusting part. Thus, it is possible to engage and disengage
the reinforcing part with the adjusting part. By this an easy and reliable way for
connecting and disconnecting the reinforcing part and the adjusting part is realized.
[0028] According to an embodiment of the present subject matter, the at least two receiving
means of the size adjusting part are arranged in sequence. Preferably, the at least
two receiving means are positioned such that the length of the hip wing is variable.
Due to this arrangement the relative position of the reinforcing part and the size
adjusting part is modifiably adjustable. Thus, the sequence of the receiving means
is adapted to determine the length of the hip wing. Depending on the distance of the
at least two receiving means to each other, predetermined positions and a predetermined
length, respectively, of the hip wing is determined for the respective position of
the at least two receiving means.
[0029] According to an embodiment of the present subject matter, the size adjusting part
and/or the reinforcing part comprises a locking means, preferably securing the reinforcing
part to the size adjusting part. Advantageously, the locking means is a retaining
clamp. Such locking means prevents detaching of the size adjusting part from the reinforcing
part and vice versa. Thus, the security using a hip wing having such a locking means
can be enhanced. An easy and cost efficient solution for a locking means is a retaining
clamp. This clamp typically clamps the reinforcing part and preferably one of its
ends (first end, second end) and at least one contact means, respectively, in a position
in which a disengaging of the end with the size adjusting part can be prevented. Clamping
can be improved by a groove provided on the at least one contact means, in particular
at the ends of the reinforcing part.
[0030] According to an embodiment of the present subject matter, the reinforcing part and
the size adjusting part comprise a curved-shape, preferably adapted to human hip.
Thus, a hip belt and its hip wing, respectively, encircle optimally a hip of a user
such that a load carried in a backpack can be load-distributed to the hip bone of
the user in an optimal manner. Hence, a convenient comfort in carrying and wearing,
respectively, of a hip wing can be realized.
[0031] Preferably, the size adjusting part forms an extension of the curved-shape of the
reinforcing part. Thus, the curved-shaped of the reinforcing part can be optimally
prolonged such that an adaption to human hip of different and several users, respectively,
is realized.
[0032] According to an embodiment of the present subject matter, the contours of the reinforcing
part and the size adjusting part are adapted to each other. By this, an extension
of e.g. the curved-shaped of the reinforcing part is possible in a telescopic manner.
This allows a perfectly fitted hip wing to human hips of different users.
[0033] According to a further embodiment of the present subject matter, the reinforcing
part and/or the size adjusting part comprise a hook-and-loop fastener for attaching
a pad. A pad typically comprises a surface having a convenient wearing comfort for
a user. Due to the hook and loop fastener an easy way for cleaning the pad is realized.
Further, depending on the relative position of the size adjusting part to the reinforcing
part a pad adapted to the size and the distance of the aforementioned part, respectively,
is positionable to the reinforcing part and/or the size adjusting part.
[0034] According to a second aspect of the present subject matter, a hip belt has a central
bridging section, at least one hinge, and at least one hip wing, wherein the at least
one hinge pivotably connects the at least one hip wing to the central bridging section.
[0035] Such an embodiment with the at least one hinge guarantees that the at least one hip
wing is pivotable to the central bridging section and vice versa. Thus, an adaption
to a human hip of such a hip belt is realizable. Further, the pivoting allows an adaption
to different hips such that a hip wing and a hip belt, respectively, of the present
invention is usable for e.g. a woman and a man.
[0036] According to an embodiment of the present subject matter, the hip wing employed in
the second aspect can be structured as discussed for the first aspect and corresponding
embodiments.
[0037] According to an embodiment of the present subject matter, the at least one hinge
comprises at least one pivoting area. The pivoting area preferably comprises a contact
area such that a bending above the pivoting area is restricted. Advantageously, the
at least one hinge is arranged at the central bridging section. Thus, in case of a
mounting of the central bridging section to a backpack the at least one hip wing is
pivotable about the hinge, the at least one hinge and the central bridging section,
respectively.
[0038] According to an embodiment of the present subject matter, the at least one hinge
comprises two pivoting areas spaced from each other. This further enhances the prevention
of bending moments and movements, respectively, so that the mechanical stability of
such an arrangement is enhanced. Preferably, the two pivoting areas comprise a common
pivoting axis. This guarantees an easy and smooth running movement of the at least
one hip wing about the central bridging section.
[0039] According to a further embodiment of the present subject matter, the reinforcing
part is guided by the at least one hinge. Thus, the pivoting movement of the reinforcing
part of the at least one hip wing is guided in its rotation by the at least one hinge.
Hence, the at least one hinge specifies the movement of the reinforcing part about
the hinge and the central bridging section, respectively.
[0040] According to an embodiment of the present subject matter, the reinforcing part comprises
a U-shaped segment restricting the relative movement in the direction substantially
parallel to a pivoting axis of the hinge. This means that the reinforcing part comprises
at least one segment which is not aligned in line with a common pivoting axis of the
two pivoting areas and one pivoting area, respectively, so that a movement of the
reinforcing part along the pivoting axis is restricted.
[0041] Preferably, the U-shaped form is positioned between two pivoting areas of the at
least one hinge. As already explained above, the U-shaped form realizes that a part
of the reinforcing part is not coaxially aligned to a pivoting axis of the hinge.
This part is arranged outside of a pivoting area of the at least one hinge such that
the U-shaped form is positioned adjacent to a pivoting area. Thus, the U abuts on
the at least one hinge. This abutment restricts a translational movement of the reinforcing
part in the direction substantially parallel to the pivoting axis of the at least
one hinge.
[0042] According to an embodiment of the present subject matter, the at least one hinge
comprises a bushing. Such a bushing enhances a rotation movement. Thus, the rotation
of the reinforcing part about the central bridging section and the at least one hinge,
respectively, is enhanced due to a reduction of friction.
[0043] According to a third aspect of the present subject matter, a backpack has a hip belt
extending substantially in a horizontal direction, and a supporting element stiffening
the backpack and extending in a substantially vertical direction, wherein the supporting
element and the hip belt are relatively moveable to each other. Thus, a relative movement
of the hip belt concerning the supporting element of the backpack is realizable. Such
a movement allows a perfect adaption to the movement of a user of a backpack while
carrying such a backpack with a load. Hence, a convenient wearing comfort is provided
together with a mechanical stability of a hip belt with a backpack having a supporting
element.
[0044] According to an embodiment of the present subject matter, the backpack employed in
the third aspect can be structured as discussed for the first aspect plus corresponding
embodiments and/or for the second aspect plus corresponding embodiments.
[0045] According to an embodiment of the present subject matter, the hip belt is detachably
mounted to the supporting element. This allows an easy and comfortable adjustment
of the hip belt to a user's hip such that a load carried in a backpack can be perfectly
distributed on the user's hip and hip bone, respectively. Thus, an adaption of the
hip belt to the anatomy of the user can be done before wearing a backpack having a
hip belt.
[0046] According to an embodiment of the present subject matter, the supporting element
having two ends comprises a seat element connecting the supporting element to the
hip belt. Advantageously, the seat element is adapted to transfer forces from the
supporting element and the load carried in the backpack, respectively, to the hip
belt. Preferably, the seat element is arranged at an end of the supporting element.
Thus, the seat element builds the lowest point of the supporting element at which
the hip belt can be connected. Hence, all the forces acting on a backpack having a
supporting element are transferred to the seat element which transfers the forces
received to the connected hip belt and the user's hip and hip bone, respectively.
[0047] According to an embodiment of the present subject matter, a central bridging section
of the hip belt comprises a latching element mounting the hip belt to the supporting
element. By this, an unintentional detaching of the hip belt from the supporting element
and the seat element, respectively, can be restricted. The latching element is preferably
constructed such that only an active intervention of a user allows solving and detaching,
respectively, of the hip belt from the supporting element of the backpack.
[0048] According to an embodiment of the present subject matter, the hip belt is tiltable
about the seat element of the supporting element. This means that a movement of a
user's hip and hip bone, respectively, is mainly independent from the movement of
the supporting element. Thus, by decoupling the rotational movement of the hip bone
of a user with the rotational movement of a backpack a user wearing such a backpack
saves energy. This is because the backpack mainly remains in its orientation relative
to the user while the user moves his/her hip bone during carrying the backpack.
[0049] According to a further embodiment of the present subject matter, the hip belt is
mountable to the supporting element by engaging the latching element with the seat
element of the supporting element. Thus, an easy way for connecting the hip belt with
the supporting element is realizable. Moreover, it is preferred that the hip belt
is detachable by disengaging the latching element from the seat element. This means
that by activating and using, respectively, the latching element can be disengaged
from the seat element. Such a disconnecting and disengaging, respectively, allows
a perfect adaption of a hip belt to a user's hip bone. Again, the adaption optimally
transfers loads from the backpack to the hip belt and the hip of a user, respectively
due to a load distribution to the hip.
[0050] According to an embodiment of the present subject matter, the hip belt is pivotably
arranged such that the hip belt is rotatable at least in a direction substantially
perpendicular to the extending direction of the supporting element.
[0051] Such a rotation movement allows an independent movement of the backpack and the hip
belt, respectively. Thus, while carrying a backpack the hip of a user normally makes
a pivoting movement which can be compensated by the pivotable arrangement of the hip
belt to the supporting element. This enhances the wearing comfort as carrying such
a backpack is more convenient to a user.
[0052] Preferably, the hip belt is arranged at the supporting element in a gyroscopic way.
Such allows a three dimensional movement of the hip belt, wherein this movement is
decoupled from the movement of the backpack and the supporting element, respectively.
Thus, an enhanced decoupling of the movements of the hip belt and the backpack is
realized. Such a mounting enhances the wearing comfort for a user.
[0053] According to an embodiment of the present subject matter, the seat element and the
latching element form a snap-in-mounting. This is an easy and reliable way to connect
the hip belt with the supporting element. Such a mounting is also cost efficient and
has a low maintenance. Preferably, the latching element snaps into the seat element.
Advantageously, the latching element is formed like a slot having a hook and an end
of the seat element is formed like a recess which is engageable with the hook.
[0054] Moreover, it is preferred that the seat element comprises a through hole. By this
a rotation about the hole of the hip belt can be easily realized.

DESCRIPTION OF THE EMBODIMENTS
[0056] In the following an embodiment of the present subject matter is explained based on
the drawings. It is noticed that the drawings show a specific embodiment as explained
below and further alternative modifications as specified in the description are at
least in part not illustrated. Further, same reference signs used in the figures denote
same components.
EMBODIMENT
[0057] An embodiment of a hip wing 1 of a hip belt 20 of the present subject matter is shown
in a plan view in Figure 1.The hip wing 1 comprises a size adjusting part 2 and a
reinforcing part 3 which are positioned in a first relative position to each other.
The size adjusting part 2 comprises six receiving means 5a, 5b, 5c, 5d, 5e, 5f for
engaging with the reinforcing part 3. The receiving means are - as shown - arranged
in sequence. The sequence consists of a matrix having three columns and two rows.
Each receiving means is constructed as a socket in which a further component can be
introduced for engaging.
[0058] The sockets of a row are oriented in the same direction. However, the sockets of
the two columns and each column, respectively, comprise two sockets oriented in different
positions. This means that e.g. the sockets 5e, 5f engaged by the receiving means
3 forms a "V", wherein the "V" has its open side directed to the left and its acute
side to the right. By this, the rotation angle of the reinforcing part 3 about the
sockets 5a, 5b, 5c, 5d, 5e, 5f of the size adjusting part 2 can be limited. Thus,
the orientation of the sockets 5a-5f relative to each other influences the rotation
of the reinforcing part 3 about the size adjusting part 2. Hence, the orientation
of the sockets functions as a stiff joint so that the reinforcing part 3 and the size
adjusting part 2 act as one part.
[0059] The reinforcing part 3 comprises two contact means 4a, 4b which engage with and are
introduced into, respectively, the sockets 5e, 5f. Due to this engagement a first
length L1 of the hip wing 1 is realized, wherein the length L1 is measured from one
end of the reinforcing part 3 to the opposite end of the size adjusting part 2. Thus,
the maximum length of the hip wing 1 is characterized by the length L1 in Figure 1a.
[0060] Figure 1b shows a plan view of the size adjusting part 2 and the reinforcing part
3 of the hip wing 1 disengaged from each other. By this, the whole size adjusting
part 2 and the whole reinforcing part 3 are shown separately, wherein the shape of
the reinforcing part 3 is depicted.
[0061] The reinforcing part 3 comprises a flexible wire having a round cross-section, wherein
the wire is made of spring steel. Also other steel or metal is possible. Moreover,
the reinforcing part 3 is formed in a sigma-shape. The sigma shape comprises three
U-shaped segments U1, U2, U3, wherein U1 connects U2 to U3. Further, U2 and U3 comprise
the same shape, but, U3 is upside down with regard to U2. The open end of the U-shaped
U1 is oriented to the left, wherein the open ends of U2 and U3 face each other.
[0062] The reinforcing part 3 comprises two sections 6a, 6b positioned adjacent to each
other. In the first section 6a the reinforcing part 3 can be pivotably arranged, in
particular at the portions connecting the U1 segment with the U2 and U3 segments,
respectively. Further, in the portions connecting the segments U1 with U2 and U1 with
U3 a mounting of the reinforcing part 3 is realized so that it is possible to mount
the reinforcing part 3 to a further member.
[0063] In the second section 6b the reinforcing part 3 comprises a recess and a gap, respectively.
Due to this gap a first and second end 4a, 4b are built forming the contact means
4a, 4b of the reinforcing part 3. Due to the U-shape of U2 and U3, respectively, the
ends 4a, 4b are formed like a hook (e.g. formed in an "L"-shape) in the second section
6b.
[0064] Further, the hook-formed contact means and the ends 4a, 4b, respectively, are engageable
with the size adjusting part 2 as can be seen in Figures 1a and 1c. For this, the
ends 4a, 4b are introduced into sockets 5a-5f. In order to hold the ends 4a, 4b reliably
in the sockets, the first and the second hook-formed end 4a, 4b of the reinforcing
part 3 are springingly mounted such that a force pushes the two ends 4a, 4b together
for closing the sigma-shape. Such a spring force is generated by the sigma-shape in
combination with e.g. spring steel for the reinforcing part 3.
[0065] By forming the sigma-shape an easy and cost effective way of building a spring and
a spring force, respectively, is realized. Thus, the first 4a and second end 4b of
the sigma-shaped reinforcing part 3 are pushed together such that the spring force
tries to close the recess in the second section 6b of the sigma-shaped reinforcing
part 3.
[0066] In case that a material is used having no spring characteristics, it is also possible
that the size adjusting part and the reinforcing part 3 and its first and second end
4a, 4b comprise locking means securing the reinforcing part 3 to the size adjusting
part 2. In this context, it is preferred that the reinforcing part 3 comprises e.g.
a groove as a locking means in which a retaining clamp being a locking means of the
size adjusting part 2 engages the first and the second end 4a, 4b, respectively. Thus,
the ends of the reinforcing part 3 cannot be disengaged from and pulled out of the
sockets 5a to 5f, respectively, of the size adjusting part 2. This is because each
retaining clamp abuts against the size adjusting part and restricting thus the movement
of the reinforcing part 3.
[0067] In Figure 1a the spring force generated by the sigma-shaped reinforcing part 3 holds
the first and second end 4a, 4b and the contact means, respectively, in the sockets
5e and 5f. Same is shown in Figure 1c, whereas the first and second end 4a, 4b are
engaged in the sockets 5a and 5b. However, in Figure 1b a force acts in opposite directions
to the spring force of the reinforcing part 3. This means that the segments U2 und
U3 and the first and second end 4a, 4b of the reinforcing part 3, respectively, are
moved in opposite directions (U3 upwards and U2 downwards). By this, the first and
second end 4a, 4b are disengaged from the sockets 5e, 5f of Figure 1a. Thus, two disconnected
parts (the reinforcing part 3 and the size adjusting part 2) are obtained as shown
in Figure 1b.
[0068] Moreover, by comparing Figure 1a with Figure 1b, a force acting on the segments U2
und U3 in Figure 1b against the spring force of the sigma-shape increases the distance
D between the first and second end 4a, 4b. Thus, the distance D in Figure 1b is greater
than in comparison to Figure 1a or also Figure 1c.
[0069] This increase in distance D also enables an engagement of the contact means 4a, 4b
with the receiving means 5a-5f and the sockets, respectively, in another position
as shown e.g. in Figure 1a.
[0070] Figure 1c shows the hip wing 1 of the hip belt 20 of the present subject matter in
a plan view, wherein the size adjusting part 2 and the reinforcing part 3 are positioned
in a second relative position to each other.
[0071] In this second relative position the first and second end 4a, 4b of the reinforcing
part 3 are engaged in the sockets 5a, 5b. Due to this engagement a second length L2
of the hip wing 1 is realized, wherein the length L2 is measured from one end of the
reinforcing part 3 to the opposite end of the size adjusting part 2. Thus, the maximum
length of the hip wing 1 is characterized by the length L2 in Figure 1c.
[0072] By this, a greater length L2 in comparison to the length L1 shown in Figure 1a is
realized. Thus, such a hip wing 1 can be worn and fitted, respectively, to another
hip of a person in comparison to that one shown in Figure 1a.
[0073] Moreover, with regard to Figures 1a to 1c also a third relative position of the size
adjusting part 2 and the reinforcing part 3 is realizable. Because the contact means
4a, 4b can also engage the sockets 5c and 5d of the size adjusting part 2. By this,
a third length L3 of the hip wing 1 can be adjusted, wherein the length L3 is greater
than L1, but shorter than L2. Hence, L3 comprises a length between L1 and L2.
[0074] Thus, the six receiving means 5a-5f and the sockets, respectively, are positioned
such on the size adjusting part 2 that the length L of the hip wing 1 is variable.
This is realized by the arrangement in a sequence having a matrix of three columns
and two rows. For further relative positions of the size adjusting part 2 to the reinforcing
part 3 it is possible that further sockets are arranged at the size adjusting part.
Moreover, also the distance of the sockets to each other can be varied to change the
length of the hip wing 1.
[0075] Summarizing the above, the size adjusting part 2 and the reinforcing part 3 are adjustable
to each other. This is realized as the contact means 4a, 4b of the reinforcing part
3 are arranged for modifiably adjusting the position of the reinforcing part 3 in
relation to the size adjusting part 2 by selectively engaging the contact means 4a,
4b with the receiving means 5a-5f.
[0076] Figure 2a shows a hip belt 20 with two hip wings 1 in a first length L4. The hip
belt 20 comprises a central bridging section 21, two hinges 22a, 22b and two hip wings
1a, 1b, wherein the hinges are arranged on opposite sides of the central bridging
section 21. Each hip wing 1a, 1b has a reinforcing part 3a, 3b and a size adjusting
part 2a, 2b, wherein contact means 4a, 4b, 4c, 4d and first and second ends 4a, 4b,
4c, 4d, respectively, engage sockets and receiving means 5e, 5f, 5k, 5l, respectively.
[0077] Due to this engagement a first length 4 of the hip belt 20 is realized, wherein the
length 4 is measured from an end of the left size adjusting part 2a to the opposite
end of the right size adjusting part 2b. Thus, the maximum length of the hip belt
20 is characterized by the relative position of the reinforcing parts 3a, 3b and the
size adjusting parts 2a, 2b.
[0078] For a more detailed description of the hip wings 1a, 1b it is referred to Figures
1a to 1c as a hip wing 1 is there already described. This description of the hip wing
1 of Figures 1a to 1c applies by analogy, whereby the contact means 4c, 4d of the
left wing 1a are engagable with the sockets and the receiving means 5g, 5h, 5i, 5j,
5k, 5l, respectively. Thus, the length of the left hip belt is also adjustable.
[0079] The hinges 22a, 22b and the hip wings 1a, 1b, respectively, are spaced from each
other in a horizontal direction H. Further, the hinges pivotably connect the hip wings
1a, 1b to the central bridging section 21. Thus, the hip wings 1a, 1b are rotatable
about the central bridging section 21.
[0080] In the following for the sake of ease only the right hip wing 1a of the hip belt
20 is described, wherein the explanations made apply also for the left hip wing 1b
by analogy. Further, it is referred to the description of Figures 1a to 1c concerning
explanations of the hip wing. These explanations made to Figures 1a to 1c also apply
here by analogy.
[0081] The right hinge 22a comprises two pivoting areas 23a, 23b which are spaced from each
other in a vertical direction V, wherein the pivoting areas 23a, 23b have a common
pivoting axis A. The space between the areas 23a, 23b enhances the prevention of bending
moments so that the mechanical stability of such an arrangement is enhanced.
[0082] The hinge 22a and the pivoting areas 23a, 23b, respectively, guide the reinforcing
part 3a, in particular in the first section 6a of the reinforcing part 3a of the hip
wings 1a. Further, the hinge 22 comprises a bushing (not shown) which allows a reliable
rotation of the reinforcing part 3a together with the size adjusting part 2a about
the pivoting axis A.
[0083] The hinge 22a and the pivoting areas 23a, 23b, respectively, extend mainly in a vertical
direction V such that a rotational movement of the reinforcing part 3a about the axis
A is guaranteed.
[0084] Between the two pivoting areas 23a, 23b of the hinge 22a the reinforcing part 3a
comprises the U-shaped segment U1 which is already explained with regard to Figures
1a to 1c. The U-shaped segment U1 restricts a movement of the reinforcing part 3a
relative to the central bridging section 21 in a direction substantially parallel
to the pivoting area axis A of the hinge 22a. Hence, due to the two-part hinge 22
having the two pivoting areas 23a, 23b only a rotational movement of the reinforcing
means 3a relative to the central bridging section 21 is possible, whereas a translational
movement is restricted.
[0085] The sigma-shaped reinforcing part 3a is an easy and cost effective way of forming
a spring and a spring force, respectively. The spring force acts on the first 4a and
second end 4b of the sigma-shaped reinforcing part 3a so that the ends 4a, 4b are
pushed together such that the spring force tries to close the recess in the second
section 6b of the sigma-shaped reinforcing part 3a.
[0086] As shown in Figure 2b, the first end 4a as well as the second end 4b of the reinforcing
part 3a is bent without any translational movement of the reinforcing part 3a in comparison
to Figure 1a. For bending a force acts in opposite directions to the spring force
of the reinforcing part 3a. This means that the segments U2 und U3 and the first and
second end 4a, 4b of the reinforcing part 3a, respectively, are moved in opposite
directions (U3 upwards and U2 downwards). Thus, the first and second end 4a, 4b are
disengaged from the sockets 5e, 5f of Figure 2a. Hence, the reinforcing part 3a is
disconnected from the size adjusting part 2a as shown in Figure 2b. And thus, the
first and second end 4a, 4b of the reinforcing part 3 with the sockets 5e, 5f of the
size adjusting part 2a is disengaged.
[0087] In other words, a bending force acts on the segments U2 und U3 in Figure 2b against
the spring force of the sigma-shaped reinforcing means 3. Thus, the distance D between
the first and second end 4a, 4b is increased, wherein the distance D in Figure 2b
is greater than in comparison to Figure 2a or also Figure 2c.
[0088] This increase in distance D also enables an engagement of the contact means 4a, 4b
with the receiving means 5a-5f and the sockets, respectively, in another position
as shown e.g. in Figure 2a comparing with Figure 2c. Due to the bending of the first
and second end portions 4a, 4b of the reinforcing part 3a, the size adjusting part
2a - as shown in Figure 2b - is detached from the hip belt 20.
[0089] Figure 2c shows a hip belt 20 with two hip wings 1 in a second length L5. In this
Figure the size adjusting part 2a of the hip wing 1a of Figure 2b is attached to the
reinforcing part 3a and the central bridging section 21, respectively. Further, the
first and the second ends 4a, 4b are again attached to the size adjusting part 2a,
but, in other sockets 5a, 5b as shown in comparison to Figure 2a. Same applies for
the left hip wing 1b by analogy.
[0090] As can be easily understood with regard to Figures 2a and 2b, the length L5 of the
hip belt 20 as shown in Figure 2c is greater than the length L4 of the hip belt 20
as shown in Figure 2a. Thus, the length of the hip belt 20 is variable and adaptable
to different human being's hip anatomy.
[0091] Figure 2d shows the hip belt 20 of Figure 2c having a cover 3oa, 3ob on the hip wings
1a, 1b. The covers comprise a cushion absorbing shocks from the hip belt 20 to e.g.
the back of a user. Further, the reinforcing part 3a, 3b and/or the size adjusting
part 2a, 2b can comprise on a surface a hook-and-loop fastener for attaching the covers
3oa, 3ob to of the parts 2a, 2b, 3a, 3b. This realizes an easy and reliable connection
between two parts 2, 3 and the covers 3oa, 30b.
[0092] Figure 2e shows the hip belt 20 of Figure 2d in a back view together with three different
pads 31a, 31b, 31c. The pads 31 differ with regard to their width W1, W2, W3. This
is because of the adjustability of the hip wing 1 and the size adjusting part 2 in
connection with the reinforcing part 3, respectively. Because of the adjustability
of the size adjusting part 2 relative to the reinforcing part 3 and the central bridging
section 21, respectively, the length of the hip belt 20 is variable. Thus, the distance
between the covers 30a, 30b differs. Depending on that distance and the length of
the hip belt 20, respectively, the corresponding pad 31a, 31b, 31c is used. This means
the greater the length of the hip belt 20 the greater the pad 31a, 31b, 31c, wherein
the pad 31a comprises the largest width W1 and 31c the smallest width W3. Further,
instead of using three parts, namely two covers and one pad, only a one-part pad can
be used.
[0093] Further, also the pads 31a, 31b, 31c use cushioning means to absorb shocks from the
hip belt 20 and its central bridging section 21, respectively, to the back of a user.
Moreover, the pads 31a, 31b, 31c as well as the central bridging section 21 comprise
a surface having a hook-and-loop fastener to detachably mount a pad to the central
bridging section 21.
[0094] Figure 2f shows a plan view of the hip belt 20 of Figure 2e with one assembled pad.
More precisely, in Figure 2f the pad 31a having a mating surface is attached to the
hip belt 20 and its central bridging section 21, respectively, also having a mating
surface. The mating surfaces comprise as already mentioned a hook-and-loop fastener.
Due to the assembled pad 31a a continuous area is realized giving a comfortable feeling
to a user wearing such a hip belt 20.
[0095] Figure 3a shows a plan view of backpack 40 with a supporting element 41 and a hip
belt 20, wherein the hip belt 20 extends substantially in a horizontal direction H
and the supporting element 41 stiffens the backpack 40 and extends in a substantially
vertical direction V.
[0096] The supporting element 41 comprises a mainly rectangular solid shape and has two
ends 41a, 41b and a seat element 42. The seat element 42 serves for connecting the
supporting element 41 to the hip belt 20. Further, the seat element 42 is arranged
at the lower end 41b of the supporting element 41. As can be further seen in Figure
3a, the seat element 42 comprises a through hole 42a which is adapted to engage with
a latching element 43 of the central bridging section 21 of the hip belt 20.
[0097] The central bridging section 21 comprises the latching element 43 which mounts and
holds, respectively, the hip belt 20 to the supporting element 41, wherein the central
bridging section 21 and the hip belt 20, respectively, is detachably mounted to the
supporting element 41. The latching element 43 is adapted such that the element engages
with the through hole 42a of the seat element 42. Due to this arrangement, the supporting
element 41 and the hip belt 20 are relatively moveable to each other.
[0098] Whereas in Figure 3a the supporting element 31 and the hip belt 20 are disengaged
from each other, Figures 3b shows the second end 41b of the supporting element 41
engaged with the hip belt 20 and its central bridging section 21, respectively. Thus,
the latching element 43 interacts with the through hole 42a so that a relative translational
movement of the central bridging section 21 and the supporting element 41 of the backpack
40 is restricted along the vertical direction V.
[0099] Figure 4a shows an enlarged plan view of Figure 3b, wherein the supporting element
41 is engaged with the bridging section 21. As shown, the latching element 43 comprises
a round shape so that the hip belt 20 is tiltable about the seat element 42 of the
supporting element 41. In other words, due to the round shape of the latching element
43 and the through hole 42a in which the latching element engages a rotational movement
of the central bridging section 21 relative to the supporting element 41 is possible,
wherein the rotation axis is oriented substantially perpendicular to the plane of
projection of Figure 4a.
[0100] Further, the seat element 42 and the latching element 43 form a snap-in-mounting
44, wherein the latching element 43 snaps into the seat element 42 and its through
hole 42a, respectively.
[0101] Figure 4b is a cross-section along line A-A of Figure 4a. Figure 4b shows the central
bridging section 21 and the latching element 43 in cross section, wherein the latching
element is formed like a slot 45 for receiving the supporting element 41 and its seat
element 42, respectively, inside.
[0102] At a lower closed end opposite to an open end at which the supporting element 41
is received, the central bridging section 21 of the hip belt 20 comprises mentioned
latching element 43 for mounting the hip belt 20 to the supporting element 41.
[0103] The latching element 43 comprises a hook for engaging with the seat element 42 and
the through hole 42a, respectively, of the supporting element 41. The hook is elastically
deformable. Thus, the hook of the latching element 43 is movable for engaging and
disengaging the supporting element 41 with and from, respectively, the central bridging
section 21. Further, for enhancing the mechanical stability the supporting element
41 comprises a protrusion 46. This protrusion serves as an additional support restricting
bending moments while the supporting element 41 is introduced in the slot 45 of the
central bridging section 21 (see Figure 4b).
[0104] When the end 41b of the supporting element 41 and its seat element 42, respectively,
engages the slot 45 of the central bridging section 21 the latching element 43 and
the hook 43a, respectively, are pressed in a horizontal direction to the outside of
the slot 45 and the central bridging section 21, respectively. After the seat element
42 and the end 41b, respectively, has passed by the latching element 43, the hook
snaps into the trough hole 42a of the seat element 42. Thus, the supporting element
41 is translationally fixed to the central bridging section 21.
[0105] While the hip belt 20 is mountable to the supporting element 41 by engaging of the
latching element 43 with the seat element 42 of the supporting element 41, the hip
belt 20 is also detachable by disengaging the latching element 43 from the seat element
42. This is done by pressing the latching element 43 and the hook 43a, respectively,
in the horizontal direction H such that the hook moves to the outside of the central
bridging section 21. By this, the through hole of the supporting element 41 and the
end 41b, respectively, is not engaged anymore by the latching element 43. Thus, the
supporting element 41 can be moved in the vertical direction V relative to the hip
belt 20. By this, a position similar shown in Figure 3a is obtained.
[0106] Figure 5a shows a hip belt 20 in a three-dimensional view. In particular, Figure
5a shows the hip belt 20 of Figure 2c in the second position in which the hip belt
comprises its largest width. Moreover, the reinforcing part 3 and the size adjusting
part 2 have a curved shape. This shape is adapted to a human hip such that a load
carried in the backpack 40 can be easily carried and load-distributed to a human hip
and the hip bone, respectively. Further, the size adjusting part 2 forms an extension
of the curved shape of the reinforcing part 3. Thus, the curved-shaped of the reinforcing
part 3a, 3b can be optimally prolonged such that an adaption to human hip of different
and several users, respectively, is realized.
[0107] Figure 5b shows a backpack 40 with the hip belt 20 of Figures 3 to 5. The supporting
element 41 is attached to the hip belt 20. In particular, it is shown that the hip
belt 20 is pivotably arranged such that the hip belt 20 is rotatable in a direction
substantially perpendicular to the extending direction of the supporting element 41.
Moreover, three rotational positions of the hip belt 20 relative to the supporting
element 42 are shown, wherein the hip belt 20 is rotatable about an axis substantially
perpendicular to the plane of projection.
