BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to an opening action supporting device that supports
the opening action of a door body, and relates to an opening section device that includes
the opening action supporting device.
2. Description of the Related Art
[0002] There are times when a large force is required for opening a large-size door body
or a heavy door body from its closed state. In
JP 2017-44044 A, a configuration is disclosed that includes an opening action supporting mechanism
which, when an operation handle disposed in a vertical stile of a sliding door is
turned, simultaneously kicks the sliding door against the frame member and relieves
the force required for opening the sliding door.
[0003] In the configuration disclosed in
JP 2017-44044 A, the action of the kicking member for projecting from the vertical stile of the sliding
door to press the frame member is completely in conjunction with the action of the
operation handle. In that regard, a mechanism is installed which, at the time of opening
the sliding door, turns the operation handle in the opening direction and projects
the kicking member, and then turns the operation handle in the opposite direction
and retracts the kicking member; so that a situation is avoided in which the kicking
member is retained at the kicking position. Hence, in this configuration, after turning
the operation handle and kicking the sliding door with the kicking member, the user
needs to take off the hand from the operation handle and wait for the turning of the
operation handle in the opposite direction before opening the sliding door, thereby
making the opening operation cumbersome. Besides, the operation handle needs to be
designed on the premise of installation of an opening action supporting mechanism,
thereby making the operation handle and the opening action supporting mechanism dedicated
for each other and consequently leading to a decline in the general versatility.
[0004] The present invention is made in view of the issues faced in the conventional technology,
and it is an object to provide an opening action supporting device that enables achieving
enhancement in the operability and achieving enhancement in the general versatility
of an operation mechanism and an opening action supporting mechanism, and to provide
an opening section device that includes the opening action supporting device.
SUMMARY OF THE INVENTION
[0005] An opening action supporting device according to the present invention includes an
opening action supporting mechanism including a kicking member that is projectable
and retractable from an outer face of a door body, the opening action supporting mechanism
being configured to press a frame member supporting the door body that is openable
and closable with respect to the frame member, by using the kicking member, to kick
the door body against the frame member at time of opening the door body. An operation
mechanism providable in the door body is linked to the opening action supporting mechanism
via an interlocking member so that, when the operation mechanism is operated, the
opening action supporting mechanism operates. The opening action supporting device
according to the invention is characterized in that it includes a clutch mechanism
configured to connect the interlocking member to the opening action supporting mechanism,
and the clutch mechanism is configured to: connect the interlocking member, which
moves in one direction when the operation mechanism is operated to a predetermined
operating position in an opening direction, to the opening action supporting mechanism
to transmit movement of the interlocking member to the opening action supporting mechanism
to move the kicking member from a housing position at which the kicking member is
retracted inside the door body to a kicking position at which the kicking member is
projected outside the door body; and disconnect the interlocking member, which further
moves in the one direction when the operation mechanism is further operated from the
predetermined operating position in the opening direction, from the opening action
supporting mechanism not to transmit movement of the interlocking member to the kicking
member.
[0006] An opening section device includes: the opening action supporting device according
to the invention including the above-described configuration; the door body that is
supported by the frame member to be openable and closable with respect to the frame
member and that is provided with the opening action supporting device; the operation
mechanism that includes an operating unit exposed on an outer face of the door body;
and the interlocking member that is movably supported inside the door body.
[0007] According to such a configuration, at the time of opening the door body, the user
only has to operate the operation mechanism to the maximum operation position beyond
a predetermined operation position, so that the clutch mechanism changes from the
connected state to the disconnected state, and the locking member can be housed after
the door body has been kicked. Hence, after the door body is kicked using the kicking
member, the user can open the door body using the operation mechanism that has been
operated to the maximum operation position, thereby enabling achieving a high degree
of operability. Moreover, in the opening action supporting device, as a result of
including the clutch mechanism, the separately-designed opening action supporting
mechanism can be easily combined with the operation mechanism and the interlocking
member. For that reason, the operation mechanism need not be configured on the premise
of installation of the opening action supporting mechanism. Hence, depending on the
specifications of the opening section device, it becomes possible to install a plurality
of opening action supporting mechanisms or it becomes possible to select the presence
or absence of opening action supporting mechanisms using the same operation mechanism
and the same interlocking member. That enables achieving a high degree of general
versatility.
[0008] In the opening action supporting device according to the present invention, the clutch
mechanism can include a unidirectional transmission structure that disconnects the
interlocking member, which moves in another direction that is an opposite direction
of the one direction when the operation mechanism is operated in a closing direction,
from the opening action supporting mechanism. As a result, at the time of closing
the door, the opening action supporting mechanism is prevented from operating in conjunction
with the operation of the operation mechanism in the closing direction, and the housing
position of the kicking member is reliably maintained so that interference of the
kicking member in the closing action of the door body is avoided.
[0009] In the opening action supporting device according to the present invention, the opening
action supporting mechanism can include a first elastic member configured to bias
the kicking member in a direction in which the kicking member moves from the kicking
position to the housing position. In a state where the interlocking member that moves
in the one direction is connected to the opening action supporting mechanism by the
clutch mechanism, the kicking member can move to the kicking position against biasing
force of the first elastic member, and in a state where the interlocking member that
moves in the other direction that is an opposite direction of the one direction is
disconnected from the opening action supporting mechanism by the clutch mechanism,
the kicking member can move to the housing position due to biasing force of the first
elastic member. As a result, after having kicked the door body, the kicking member
can be reliably moved to the housing position using the biasing force of the first
elastic member.
[0010] In the opening action supporting device according to the present invention, the clutch
mechanism can include a pin member that is provided in the kicking member, a driving
member that is turnably supported by the interlocking member, that has a driving face
enabling pressing of the pin member when the interlocking member is moving in the
one direction, and that has a flank face that makes sliding contact with the pin member
when the interlocking member is moving in the other direction that is an opposite
direction of the one direction, a second elastic member configured to bias the driving
member using the driving face to a turning position at which the pin member is pressable,
and a guiding hole that includes a first guiding portion that moves the pin member
along a direction of movement of the interlocking member, that includes a second guiding
portion that is continuous from the first guiding portion and that moves the pin member
in an intersecting direction from a guiding direction guided by the first guiding
portion, and into which the pin member is movably inserted, when the operation mechanism
is operated to the predetermined position in the opening direction, as a result of
pressing of the pin member by the driving face of the driving member, the opening
action supporting mechanism can move the kicking member toward the kicking position
while the pin member is being guided by the first guiding portion, and when the pin
member moves from the first guiding portion into the second guiding portion and proceeds
to a predetermined position in the second guiding portion, the pin member can move
away from the driving face and thus the interlocking member and the opening action
supporting mechanism are disconnected from each other to allow the kicking member
to move from the kicking position to the housing position. As a result, the clutch
mechanism can be configured with a simple configuration using the pin member and the
guiding holes, and the structure of the opening action supporting device can be simplified.
Moreover, by varying the angle, the length, and the arrangement of the first guiding
portion and the tilted second guiding portion, replacing the member having the first
guiding portion and the second guiding portion enables kicking at an arbitrary operation
position. That enables achieving a high degree of general versatility at low cost.
[0011] In the opening action supporting device according to the present invention, the kicking
member can include a first arm one end portion of which is rotatably positioned and
supported with respect to the door body, a second arm one end portion of which is
rotatably linked to another end portion of the first arm and another end portion of
which is provided with the pin member, and a roller that is provided in a linking
portion for linking the first arm and the second arm, and when the pin member is pressed
by the driving face of the driving member, the first arm and the second arm are folded
with the linking portion serving as fulcrum, so that the roller protrudes from the
door body to press the frame member. As a result, while simplifying the configuration
of the kicking member, the kicking member can be made to project and retract in a
smooth manner due to the movement of the interlocking member based on the operation
of the operation mechanism.
[0012] The above and other objects, features, advantages and technical and industrial significance
of this invention will be better understood by reading the following detailed description
of presently preferred embodiments of the invention, when considered in connection
with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] An exemplary embodiment of an opening action supporting device according to the present
invention is described below in detail by describing an opening section device, which
includes the opening action supporting device, with reference to the accompanying
drawings.
[0015] FIG. 1 is a profile diagram of an opening section device 11, which includes an opening
action supporting device 10 according to the embodiment of the present invention,
when viewed from inside the room. FIG. 2 is a perspective view, when viewed from inside
the room, of the state in which a sliding door 12 of the opening section device 11
is open. As illustrated in FIGS. 1 and 2, the opening section device 11 is a fitting
that is a single-sliding-door in which the sliding door 12 and a fixed door 16 are
supported by a frame member 14.
[0016] The frame member 14 is a rectangular frame having an upper frame 14a, a lower frame
14b, a left-side vertical frame 14c, and a right-side vertical frame 14d; and has
a rectangular opening section 14e formed on the inside. The frames 14a to 14d are
extruded sections made of, for example, work timber used in fittings, or a metal such
as aluminum, or resin. The frame member 14 is fixed to an opening section provided
in a building skeleton.
[0017] In the application concerned, the room inside-outside direction of the opening section
device 11, that is, the direction from the inside of the room toward the outside of
the room or the opposite direction is called as a depth direction (in the drawings,
the direction indicated by an arrow Y); and the face extending along the depth direction
is called as a depth face. The orthogonal direction to the depth direction is a width
direction. In the case of the vertical frame 14c that is elongated in the vertical
direction, the horizontal direction that is orthogonal to the longitudinal direction
of the vertical frame 14c (in the drawings, the direction indicated by an arrow X)
represents the width direction. In the case of the upper frame 14a that is elongated
in the horizontal direction, the vertical direction that is orthogonal to the longitudinal
direction of the upper frame 14a (in the drawings, the direction indicated by an arrow
Z) represents the width direction. The face extending along the width direction is
called as a width face. Meanwhile, the inside (inner periphery) of the frame-shaped
member implies, for example, the inner side of the frame member 14; and the outside
(outer periphery) of the frame-shaped member implies, for example, the outer side
of the frame member 14 that is fixed to the building skeleton.
[0018] The fixed door 16 is a rectangular stile having an upper stile 16a, a lower stile
16b, a left-side vertical stile 16c, and a right-side vertical stile 16d; and holds
a face bar 18 on the inside. Of the fixed door 16, the upper stile 16a is fixed to
the depth face of the upper frame 14a, and the lower stile 16b is fixed to the depth
face of the lower frame 14b. Moreover, the vertical stile 16c is fixed to the depth
face of the vertical frame 14c of the frame member. As a result, the fixed door 16
blocks approximately the left half of the opening section 14e of the frame member
14. The face bar 18 is made of, for example, a glass plate, a resin plate, or a wooden
plate.
[0019] The sliding door (door body) 12 is a rectangular stile having an upper stile 12a,
a lower stile 12b, a left-side vertical stile 12c, and a right-side vertical stile
12d; and holds a face bar 20 on the inside. The sliding door 12 is slidably supported
along the longitudinal direction of the lower frame 14b and in between the upper frame
14a and the lower frame 14b. As a result, the sliding door 12 is openable and closable
with respect to the area in approximately the right half of the opening section 14e
of the frame member 14. The face bar 20 is made of, for example, a glass plate, or
a resin plate, or a wooden plate.
[0020] In the vertical stile 12d representing a stile on a leading end side of the sliding
door 12; a lock mechanism 22, an operation mechanism 24, and the opening action supporting
device 10 are disposed. The opening action supporting device 10 includes an opening
action supporting mechanism 26, which is embedded in a casing 25, and a clutch mechanism
28 (see FIG. 3). The casing 25 is fixed to the vertical stile 12d using a screw 27.
[0021] The lock mechanism 22 is a mechanism for locking and unlocking the sliding door 12
with respect to the frame member 14. The opening action supporting mechanism 26 is
a mechanism that, at the time of opening the sliding door 12 from the closed position,
kicks the sliding door 12 out from the frame member 14 so as to relieve the force
required in opening the sliding door 12. The operation mechanism 24 is a mechanism
that includes an operation handle 29 representing an operating unit exposed from the
outside face of the sliding door 12; that enables locking an unlocking of the lock
mechanism 22 as a result of the turning actions of the operation handle 29; and that
is used to operate the opening action supporting mechanism 26. The clutch mechanism
28 is a mechanism for connecting the interlocked state between the operation mechanism
24 and the opening action supporting mechanism 26.
[0022] FIG. 3(A) is an enlarged main-part cross-sectional view illustrating the state of
the mechanisms 22, 24, and 26 when the operation handle 29 is at a 0° position and
the sliding door 12 is locked. In FIGS. 3(B) and 4(A) are illustrated states attained
when the operation handle 29 is turned by respective turning angles (to a 145° position
and a 180° position) in the opening direction from the state illustrated in FIG. 3(A).
In FIG. 4(B) is illustrated the state attained when the operation handle 29 is turned
to an 89° position in the closing direction from the state illustrated in FIG. 4(A).
In the present embodiment, when the mechanisms 22, 24, and 26 are viewed from the
inside of the room as illustrated in FIGS. 3 and 4; the position at which the operation
handle 29 is oriented vertically upward represents the 0° position, and the position
at which the operation handle is oriented vertically downward represents the 180°
position. Moreover, the direction of turning the operation handle 29 in the counterclockwise
direction represents the operation direction (opening direction) at the time of opening
the closed sliding door 12, and the direction of turning the operation handle 29 in
the clockwise direction represents the operation direction (closing direction) at
the time of closing the open sliding door 12. However, the angular position of the
operation handle 29 as well as the turning direction and the turning range of the
operation handle 29 at the time of opening and closing the sliding door 12 as explained
herein is only exemplary, and can be appropriately varied.
[0023] As illustrated in FIGS. 3 and 4, the operation mechanism 24 includes the operation
handle 29 and an intermediate actuator 30. Regarding the actions of the operation
mechanism 24, a turning movement is converted into a linear movement by the intermediate
actuator 30, and the linear movement is then transmitted to the lock mechanism 22
and the opening action supporting mechanism 26 via a slidable interlocking member
32 (described later) that is embedded in the casing 25.
[0024] The operation handle 29 is a substantially L-shaped handle (see FIG. 2) that is disposed
in a turnable manner with respect to a mount 35 which is fixed to a room-side width
face 34 of the vertical stile 12d. The operation handle 29 has a handle shaft 29a
protruding in the depth direction from the mounting face with respect to the mount
35. The handle shaft 29a is a prismatic member that is inserted through the mount
35 in a rotatable manner and is then non-rotatably fit with a cam member 36. In the
present embodiment, the operation handle 29 can be turned in the opening direction
from the 0° position illustrated in FIG. 3(A) to the 180° position illustrated in
FIG. 4(A) in the counterclockwise direction with reference to the drawings, and can
be turned in the closing direction from the 180° position illustrated in FIG. 4(A)
to the 0° position illustrated in FIG. 3(A) in the clockwise direction with reference
to the drawings.
[0025] The intermediate actuator 30 is fixed to the casing 25, and the room-side face of
the intermediate actuator 30 facing the mount 35 has the cam member 36 rotatably supported
thereon. The cam member 36 is a substantially elliptical disk capable of performing
coaxial rotation with the handle shaft 29a, and has a link shaft 36a that projects
at an eccentric position from the shaft center of the handle shaft 29a. The link shaft
36a rotatably supports the lower end portion of a link arm 31. When the operation
handle 29 is turned, the cam member 36 rotates along with the handle shaft 29a. As
a result, the link shaft 36a swings around the handle shaft 29a and moves the link
arm 31 in the vertical direction.
[0026] The link arm 31 is a substantially boomerang-shaped plate disposed along the vertical
direction. The link arm 31 has the lower end portion rotatably linked to the link
shaft 36a, and has the upper end portion rotatably linked to a connecting shaft 38a
that is a rotating shaft disposed in a linking member 38 constituting the interlocking
member 32.
[0027] As illustrated in FIGS. 3 and 4, the interlocking member 32 includes the linking
member 38, an interlocking lever 40, and a coupling member 41; and is disposed inside
the vertical stile 12d to slide in the vertical direction.
[0028] The linking member 38 is a plate member extending in the vertical direction, and
is disposed inside the vertical stile 12d in a slidable manner with respect to the
vertical stile 12d. To the linking member 38, the actions of the operation mechanism
24 (the operation handle 29) are transmitted via the cam member 36 and the link arm
31. The linking member 38 includes an upper linking portion 38b at the upper end portion,
a lower linking portion 38c at the lower end portion, and a base portion 38d that
joins the upper linking portion 38b and the lower linking portion 38c. The upper linking
portion 38b and the lower linking portion 38c are linked to the interlocking lever
40 using a clip 39. The base portion 38d includes the connecting shaft 38a and has
a plurality of long holes 38e formed therein. The connecting shaft 38a protrudes from
the surface on the side of the mount 35, and is shaft-supported at the upper end portion
of the link arm 31. There are, for example, three long holes 38e formed in the vertical
direction, and a guide pin 30b protruding from a guide face member 30a of the intermediate
actuator 30 is slidably inserted in each long hole 38e. Since the long holes 38e are
guided by the guide pins 30b, the vertical sliding of the linking member 38 (and the
intermediate actuator 30) with respect to the vertical stile 12d is guided.
[0029] The interlocking lever 40 is supported inside the vertical stile 12d in a vertically
slidable manner with respect to the vertical stile 12d, and is formed as a section
having a substantially H-shaped cross-section extending along the entire length of
the vertical stile 12d (see FIG. 9). The interlocking member 32 is so configured that
the linking member 38 and the coupling member 41 are linked to holes or notches formed
at various positions of the interlocking lever 40.
[0030] The coupling member 41 is a rod member extending in the vertical direction and is
fixed to the interlocking lever 40 (see FIG. 9). Although described later in detail,
the coupling member 41 is a constituent element of the opening action supporting mechanism
26 and the clutch mechanism 28.
[0031] The interlocking member 32 slides upward along with the link arm 31 that moves up
in response to the turning of the operation handle 29 in the opening direction; and
slides downward along with the link arm 31 that moves down in response to the turning
of the operation handle 29 in the closing direction (see FIGS. 3 and 4).
[0032] As illustrated in FIGS. 3 and 4, the lock mechanism 22 includes a drawing member
42 and a lock pin 44. In FIGS. 3 and 4 is illustrated the configuration in which the
lock mechanism 22 is disposed only on the lower side of the operation mechanism 24.
However, the lock mechanism 22 can be disposed at a plurality of positions along the
longitudinal direction of the vertical stile 12d, including a position on the upper
side of the opening action supporting mechanism 26 (see FIG. 5). The lock mechanisms
22 perform concurrent actions via the interlocking lever 40 that moves up and down
in response to the turning of the operation handle 29.
[0033] The drawing member 42 is a plate member extending in the vertical direction, and
is fixed to the interlocking lever 40. The drawing member 42 includes a drawing piece
42a that stands upright along the depth direction; a supporting piece 42b that is
disposed on the lower side of the drawing piece 42a, the supporting piece 42b facing
the drawing piece 42a with a gap between the supporting piece 42b and the drawing
piece 42a; and a lock opening 42c that is formed in between the drawing piece 42a
and the supporting piece 42b. The drawing piece 42a is a plate piece that is tilted
from the lower end constituting the lock opening 42c toward the upper end and in the
direction of gradually moving away from an outside depth face 46 of the vertical stile
12d, and that then extends in the vertically upward direction. The supporting piece
42b is a plate piece formed to have vertical symmetry with the drawing piece 42a.
The lock opening 42c has a substantially tapering cross-section that gradually increases
in the vertical opening width along the direction of moving away from the outside
depth face 46 of the vertical stile 12d, that is, along the direction of moving away
from the lock pin 44.
[0034] The lock pin 44 is a pin protruding toward the inside of the frame from an inside
depth face 47 of the vertical frame 14d facing the vertical stile 12d (see FIGS. 1
and 5), and includes a head portion 44a having an expanded diameter at the leading
end. In the drawings, a mounting plate 44b represents a mounting plate for fixing
the lock pin 44 to the inside depth face 47. The head portion 44a of the lock pin
44 enters the lock opening 42c and fits in the drawing piece 42a, so that a lock is
put in between the vertical stile 12d and the vertical frame 14d, that is, in between
the sliding door 12 and the frame member 14.
[0035] As illustrated in FIGS. 3 and 4, the opening action supporting mechanism 26 includes
a kicking member 48. Although described later in detail, the kicking member 48 projects
from the outside depth face 46 of the vertical stile 12d accompanying the movement
of the interlocking member 32. During the opening action of the sliding door 12, the
kicking member 48 presses the inside depth face 47 of the vertical frame 14d, so as
to support the opening of the sliding door 12. The clutch mechanism 28 is present
in between the opening action supporting mechanism 26 and the interlocking member
32. According to the angular position and the turning direction of the operation handle
29, that is, according to the sliding position and the sliding direction of the interlocking
member 32; the clutch mechanism 28 connects or disconnects the interlocked state between
the interlocking member 32 and the kicking member 48.
[0036] Given below is the explanation of a specific configuration of the opening action
supporting device 10.
[0037] FIG. 5(A) is an enlarged main-part cross-sectional view illustrating the state of
the mechanisms 22, 26, and 28 when the operation handle 29 is at the 0° position and
the sliding door 12 is locked. In FIG. 5(B) and FIG. 6(A) are illustrated states attained
when the operation handle 29 is turned by respective turning angles (to the 89° position
and the 145° position) in the opening direction from the state illustrated in FIG.
5(A). In FIG. 6(B) is illustrated a state in which the clutch mechanism 28 is disconnected
in the state illustrated in FIG. 6(A). In FIG. 7(A) is illustrated the state in which
the operation handle 29 is turned to the 180° position in the opening direction from
the state illustrated in FIG. 6(B); and in FIG. 7(B) is illustrated the state in which
the sliding door 12 is closed from the state illustrated in FIG. 7(A). In FIGS. 8(A)
and 8(B) are illustrated the states in which the operation handle 29 is turned by
respective turning angles (to the 90° position and an 86° position) in the closing
direction from the state illustrated in FIG. 7(B). FIG. 9 is an exploded perspective
view of the opening action supporting mechanism 26 and the clutch mechanism 28.
[0038] As illustrated in FIGS. 5 and 9, the opening action supporting mechanism 26 includes
a base portion 50, the kicking member 48, and a housing mechanism portion 52; and
is embedded in the casing 25. The clutch mechanism 28 includes the coupling member
41, a driving member 58, a driving pin (a pin member) 60 disposed in the kicking member
48, and guiding holes 62 formed in the housing mechanism portion 52. As illustrated
in FIG. 9, in the present embodiment, the opening action supporting mechanism 26 and
the clutch mechanism 28 are assembled in an integrated manner. However, alternatively,
the clutch mechanism 28 can be configured separately from the opening action supporting
mechanism 26, and can be disposed, for example, in between the linking member 38 and
the opening action supporting mechanism 26.
[0039] Firstly, the explanation is given about a configuration of the opening action supporting
mechanism 26. The base portion 50 is a sheet-metal member that is formed to have a
substantially U-shaped cross-section by appropriately bending both ends in the depth
direction of a vertically-extending plate. The base portion 50 is screwed to a lateral
face of the casing 25 using a plurality of screws 78 (see FIG. 9). In the base portion
50, a pair of bent pieces 50a, a pair of bent pieces 50b, a pair of bent pieces 50c,
and a pair of bent pieces 50d are disposed in parallel along the vertical direction.
The topmost bent pieces 50a have shaft holes 64 formed facing each other, and the
bottommost bent pieces 50d have the guiding holes 62 formed facing each other. On
the depth face of the base portion 50, an auxiliary plate 65 is joined and fixed using
screws 63.
[0040] The kicking member 48 includes first arms 66 on the upper side, second arms 67 on
the lower side, a connecting shaft 68, and a roller 69.
[0041] The first arms 66 and the second arms 67 are band plate members extending in the
vertical direction, and are disposed in pair and facing each other in the depth direction.
Each first arm 66 has a fixing hole 66a formed in the upper end portion and has a
connecting hole 66b formed in the lower end portion. Each second arm 67 has a linking
hole 67a formed in the upper end portion and has a movable hole 67b formed in the
lower end portion. In the first arms 66 and the second arms 67, the ends of the connecting
shaft 68 are fit by insertion in the connecting holes 66b and 67b, respectively. As
a result, the first arms 66 and the second arms 67 are foldably linked in a V-shaped
manner with the connecting shaft 68 serving as the fulcrum. On the connecting shaft
68, the roller 69 is rotatably extrapolated. In each first arm 66, an end portion
of a fixed axle 70 rotatably fits in the corresponding fixing hole 66a. The fixed
axle 70 is fit by insertion in a rotatable manner in the shaft holes 64. In each second
arm 67, an end portion of the driving pin 60 rotatably fits in the corresponding movable
hole 67b. The driving pin 60 gets rotatably and slidably engaged with the guiding
holes 62 of the base portion 50, and has a collar 60a extrapolated on the shaft center.
[0042] In the kicking member 48, the upper end portions of the first arms 66 are positioned
in the base portion 50 because of the fixed axle 70. Thus, when the driving pin 60
moves up and down along the guiding holes 62, the second arms 67 move up and down
and, at that time, there is folding in between the first arms 66 and the second arms
67 via the connecting shaft 68. As a result, the connecting shaft 68 and the roller
69 that is extrapolated on the connecting shaft 68 move in the direction away from
the base portion 50 and project from the outside depth face 46 of the vertical stile
12d (see FIGS. 5 to 8).
[0043] The housing mechanism portion 52 includes an extension arm 72 and an extension coil
spring (a first elastic member) 74. The housing mechanism portion 52 is a mechanism
that, when the opening action supporting mechanism 26 is disconnected from the interlocking
member 32 due to the clutch mechanism 28, forcibly moves the kicking member 48 to
the initial position at which the kicking member 48 is retracted inside the vertical
stile 12d (see FIG. 5(A)).
[0044] The extension arm 72 is a substantially U-shaped sheet metal member in which the
upper end portions of a pair of arm plates 72a in the depth direction are joined by
a bridge plate 72b running along the depth direction. In the lower end portion of
each arm plate 72a, a hook 72c is disposed that gets rotatably engaged with the driving
pin 60 on the inner periphery side of the pair of guiding holes 62. On the bridge
plate 72b, a supporting portion 72d is disposed in which the upper end portion of
the extension coil spring 74 gets locked. Thus, the upper end portion of the extension
coil spring 74 is locked in the supporting portion 72d. In the auxiliary plate 65,
a relief long hole 65a is formed to extend vertically for the purpose of relieving
the upper end portion of the extension coil spring 74 and the supporting portion 72d.
The lower end portion of the extension coil spring 74 is locked at a supporting member
76 that is joined to the base portion 50 and the auxiliary plate 65 using the screws
63.
[0045] When the driving pin 60 moves up and down along with the second arms 67 of the kicking
member 48, the extension arm 72 of the housing mechanism portion 52 too moves up and
down accompanying the up-and-down movement. At that time, because of having the lower
end portion fixed to the base portion, the extension coil spring 74 moves up and down
along with the extension arm 72 whose upper end portion moves up and down. That is,
when the driving pin 60 moves up against the biasing force of the extension coil spring
74, a downward biasing force gets applied to the driving pin 60 from the extension
coil spring 74.
[0046] The casing 25 has a substantially U-shaped cross-section extending along the substantially
entire length of the vertical stile 12d. The casing 25 fits in a vertical opening
formed in the substantial center in the depth direction of the vertical stile 12d,
and a depth face 25a of the casing 25 is formed in a substantially flush manner with
the outside depth face 46 of the vertical stile 12d (see FIG. 2). On the depth face
25a of the casing 25, an opening 25b through which the kicking member 48 is projectable
and retractable is formed. In the state of having the interlocking member 32 slidably
housed therein, the casing 25 is fixed to the bent pieces 50b and 50c of the base
portion 50 using the screws 78.
[0047] Given below is the explanation of a configuration of the clutch mechanism 28. The
coupling member 41 is a vertically-extending member that is fixed to an outside depth
face 40a of the interlocking lever 40 using screws 79, and that is housed in the casing
25. The coupling member 41 includes a bulging portion 41a that protrudes toward the
interlocking lever 40; a roller housing groove 41b that is a substantially C-shaped
depression extending in the vertical direction on the side of the outer face of the
bulging portion 41a; a long hole 41c that is formed in a penetrating manner in the
depth direction in the upper portion of the roller housing groove 41b; and a driving
member housing portion 41d that is a concave portion formed in the lower portion of
the roller housing groove 41b. The bulging portion 41a gets inserted in an opening
40b that is formed in the interlocking lever 40 in a penetrating manner in the width
direction. The coupling member 41 is disposed in a sandwiched manner between the arms
66 and 67 of the kicking member 48 in the depth direction, and the roller 69 is disposed
in the roller housing groove 41b. At that time, since the fixed axle 70 is inserted
in the long hole 41c, the sliding of the coupling member 41 is not blocked by the
fixed axle 70.
[0048] The driving member 58 is supported in a turnable manner on the inner periphery side
of the driving member housing portion 41d of the coupling member 41, and passes through
the opening 40b of the interlocking lever 40. The driving member 58 includes a driving
face 58a that enables lifting of the driving pin 60; a flank face 58b that extends
downward in a substantial orthogonal manner from the driving face 58a; a shaft hole
58c in which a turn shaft 82 is fit by insertion in a rotatable manner; and a stopper
piece 58d that protrudes from below the shaft hole 58c toward the inner face of the
coupling member 41. The driving member 58 has the shape of a bottomed vessel with
an inner space in which a torsion coil spring (a second elastic member) 84 is disposed.
The torsion coil spring 84 is extrapolated on the turn shaft 82. In the driving member
58, at the initial position at which no external force is exerted, the leading end
of the stopper piece 58d is set at a turning position in an abutting manner against
the inner face of the driving member housing portion 41d due to the biasing force
of the torsion coil spring 84 (see FIG. 5(A)). At the initial position, the driving
member 58 is retained in a tilted orientation in which the driving face 58a gradually
tilts upward to the side of the vertical frame 14d, and the flank face 58b gradually
tilts downward to the side of the vertical frame 14d. At that time, the driving face
58a is positioned at an overlapping position below the driving pin 60.
[0049] The guiding holes 62 are formed in the bent pieces 50d of the base portion 50, and
are positioned facing each other in a pair. The guiding holes 62 are substantially
boomerang-shaped long holes having a first guiding portion 62a running along the vertical
direction, and having a second guiding portion 62b that is continuous from the upper
end of the first guiding portion 62a and that is tilted upward in the direction of
gradually moving away from the side of the driving member 58. In the guiding holes
62, the driving pin 60 gets inserted in a slidable manner. Hence, when the driving
pin 60 moves up and down, the guiding holes 62 can vary the position of the driving
pin 60 along the width direction (the X direction) of the vertical stile 12d.
[0050] Given below is the explanation of the actions of the opening section device 11 configured
in the manner described above.
[0051] Firstly, the explanation is given about the action of opening of the sliding door
12 from the closed position illustrated in FIG. 1. When the sliding door is closed
and the lock mechanism 22 is in the locked state, as illustrated in FIG. 3(A) and
FIG. 5(A), the operation handle 29 is positioned at the 0° position and the interlocking
member 32 is positioned at the lowermost sliding position. In this state, the head
portion 44a of the lock pin 44 is engaged with the vertically-aligned portion of the
drawing piece 42a, and the lock mechanism 22 is in the locked state. In the opening
action supporting mechanism 26, since the driving pin 60 is positioned at the lower
end of the first guiding portions 62a of the guiding holes 62; the first arms 66 and
the second arms 67 are aligned substantially along the vertical direction, and the
kicking member 48 is positioned at a housing position at which the roller 69 is retracted
inside the vertical stile 12d. In the clutch mechanism 28, the driving face 58a of
the driving member 58 is positioned sufficiently away from the driving pin 60. Hence,
the sliding door 12 is closed with respect to the frame member 14, and the vertical
stile 12d is closely attached to the vertical frame 14d via a predetermined tight
material. Hence, a significant force is required for the initial motion at the time
of opening the sliding door 12.
[0052] At the time of opening the sliding door 12 from this state, firstly, the operation
handle 29 is turned in the opening direction. When the operation handle 29 is turned
in the opening direction from the 0° position, the interlocking member 32 moves up
and, at the 89° position, lifting of the driving pin 60 is started due to the driving
face 58a of the driving member 58 (see FIG. 5(B)). That is, from the 0° position to
the 89° position, the clutch mechanism 28 is in the disconnected state and the driving
member 58 is positioned away from the driving pin 60. Hence, the opening action supporting
mechanism 26 (the kicking member 48) does not operate.
[0053] In the lock mechanism 22, the drawing member 42 moves up accompanying the interlocking
member 32 even from the 0° position to the 89° position. Hence, the drawing piece
42a moves relatively upward with respect to the head portion 44a of the lock pin 44
(see FIGS. 5(A) and 5(B)). In the present embodiment, at the 89° position, a large
part of the lock pin 44 is present in the lock opening 42c (see FIG. 5(B)) and, although
not illustrated in the drawings, the lock pin 44 gets entirely disposed in the lock
opening 42c at a 96° position. Thus, the lock mechanism 22 gets unlocked. In this
way, in the opening section device 11, during the operation of unlocking the lock
mechanism 22 from the locked state, the opening action supporting mechanism 26 does
not operate in principle. For that reason, a defect in which the sliding door 12 is
kicked before the unlocking of the lock mechanism 22 can be prevented from occurring.
[0054] When the operation handle 29 is further turned from the 89° position in the opening
direction; since the clutch mechanism 28 is in the connected state, the driving face
58a of the driving member 58 lifts the driving pin 60 via the collar 60a accompanying
the rising of the interlocking member 32. As a result, the driving pin 60 moves up
inside the guiding holes 62 and lifts the second arms 67, so that there is gradual
folding in between the first arms 66 and the second arms 67 via the connecting shaft
68. With that, the roller 69 of the kicking member 48 passes through the opening 25b
of the casing 25 and protrudes to the outside from the outside depth face 46 (the
depth face 25a) of the vertical stile 12d. As a result, the roller 69 presses the
inside depth face 47 of the vertical frame 14d (see FIG. 6(A)), and the sliding door
12 slides to the open position due to the pressing force. In the present embodiment,
when the operation handle 29 is positioned at the 145° position, the amount of protrusion
of the roller 69 reaches the maximum level (kicking position). That is, at the 145°
position, the amount of kicking the sliding door 12 by the kicking member 48 reaches
the maximum level, and the action of kicking the sliding door 12 by the kicking member
48 reaches completion (see FIG. 6(A)).
[0055] During the kicking action from the 89° position to the 145° position, the driving
pin 60 moves inside the guiding holes 62 from the first guiding portion 62a to the
second guiding portion 62b. Then, while rising up in the second guiding portion 62b,
the driving pin 60 also gradually moves in the direction away from the driving face
58a of the driving member 58. In the present embodiment, at the 145° position at which
the action of kicking the sliding door 12 by the kicking member 48 reaches completion,
the driving pin 60 is positioned at the end portion of the driving face 58a, that
is, at the boundary between the driving face 58a and the flank face 58b. In the state
in which the driving pin moves up to the topmost portion of the guiding holes 62,
the amount of tensile force of the extension coil spring 74 also reaches the maximum
level, that is, the biasing force for pressing the driving pin 60 downward also reaches
the maximum level.
[0056] Thus, after causing the kicking member 48 protrude to the maximum kicking amount
at the 145° position, the driving pin 60 slips off to the flank face 58b from the
driving face 58a due to the biasing force of the extension coil spring 74, and moves
down inside the guiding holes 62 while sliding on the flank face 58b (see FIG. 6(B)).
Eventually, the driving pin 60 moves to the lower end of the first guiding portion
62a, that is, to the position same as the 0° position. Hence, the interlocked state
between the driving pin 60 and the driving face 58a of the driving member 58 is disconnected,
and the clutch mechanism 28 becomes disconnected. While the driving pin 60 moves down
inside the guiding holes 62, the kicking member 48 is gradually released from the
folded state of the first arms 66 and the second arms 67 because of the downward movement
of the second arms 67 (see FIG. 6(B)). As a result, the kicking member 48 is gradually
housed in the vertical stile 12d, and the movement of the driving pin 60 to the lower
end inside the guiding holes 62 results in the return of the kicking member 48 to
the housing position same as the 0° position.
[0057] When the operation handle 29 is further turned from the 145° position in the opening
direction, since the clutch mechanism 28 is in the disconnected state, the interlocking
member 32 moves up, but the opening action supporting mechanism 26 does not operate.
Then, as illustrated in FIG. 7(A), at the 180° position, the lock pin 44 of the lock
mechanism 22 is positioned in the lock opening 42c, and the kicking member 48 of the
opening action supporting mechanism 26 is housed in the vertical stile 12d. Hence,
when the user performs the action of opening the sliding door 12 by pulling the operation
handle 29 that is oriented vertically downward at the 180° position, it becomes easily
possible to open the sliding door 12.
[0058] In this way, the opening section device 11 includes the opening action supporting
mechanism 26 that operates in conjunction with the turning of the operation handle
29 in the opening direction. Hence, at the time of opening the sliding door 12 from
the completely-closed position, even if the sliding door 12 is, for example, large
or heavy, it can be easily opened with only a small amount of force.
[0059] Moreover, the opening section device 11 includes the clutch mechanism 28 that is
capable of connecting the interlocking member 32 and the opening action supporting
mechanism 26 in the midway of the action of turning the operation handle 29 in the
opening direction. Hence, at the time of opening the sliding door 12, the user only
needs to turn the operation handle 29 to a predetermined angular position (a predetermined
operation position; in the present embodiment, the 145° position) and then directly
turn the operation handle 29 to the turning end position (in the present embodiment,
the 180° position). That is, in the opening section device 11, according to the turning
angle at the time of turning the operation handle 29 in the opening direction, the
clutch mechanism 28 changes from the disconnected state to the connected state and
the opening action supporting mechanism 26 operates; and then the clutch mechanism
28 changes to the disconnected state and the opening action supporting mechanism 26
gets disconnected from the interlocking member 32. Thus, in the present embodiment,
due to the housing mechanism portion 52 in which the extension coil spring 74 is used,
the kicking member 48 that has been disconnected from the interlocking member 32 after
the completion of the kicking action can be automatically housed at the housing position
same as the 0° position. Meanwhile, the housing mechanism portion 52 can be omitted
as well. That is, in the configuration according to the present embodiment, when the
clutch mechanism 28 is disconnected at the 145° position, the driving pin 60 moves
down due to its own weight. Thus, even if the housing mechanism portion 52 is omitted,
the kicking member 48 can be automatically housed at the housing position after the
completion of the kicking action.
[0060] In this way, in the opening section device 11, at the time of opening the sliding
door 12, only by turning the operation handle 29 from the 0° position to the maximum
turning position (the maximum operation position; in the present embodiment, the 180°
position) beyond the predetermined angular position, the kicking member 48 is again
housed after having kicked the sliding door 12. Hence, as a result of performing the
action of opening the sliding door 12 using the operation handle 29 that has been
turned to the 180° position, the user can easily open the sliding door 12, thereby
enabling achieving a high degree of operability. Moreover, in the open state of the
sliding door 12, the kicking member 48 does not obstruct the passage. Furthermore,
since the opening section device 11 includes the clutch mechanism 28; the opening
action supporting mechanism 26 that is separately designed can be easily combined
with the operation mechanism 24 and the interlocking member 32. Hence, the operation
mechanism 24 need not be configured on the premise of installing the opening action
supporting mechanism 26. As a result, according to the specifications of the opening
section device 11, the opening action supporting mechanism 26 can be installed in
a plurality of ways, or it becomes possible to select the presence or absence of the
opening action supporting mechanism 26 using the same operation mechanism 24 or the
same interlocking member 32. That enables achieving a high degree of general versatility.
[0061] Given below is the explanation of the action of closing the sliding door 12 from
the open position illustrated in FIG. 7(A). When the sliding door 12 is opened and
the lock mechanism 22 is unlocked, as illustrated in FIGS. 4(A) and 7(A), the operation
handle 29 is positioned at the 180° position and the interlocking member 32 is positioned
at the topmost sliding position. In that state, the lock opening 42c is at a position
facing the lock pin 44 in the horizontal direction, and the lock mechanism 22 is in
the unlocked state. Moreover, the driving pin 60 is positioned at the lower end of
the first guiding portion 62a of the guiding holes 62. Hence, in the opening action
supporting mechanism 26, the kicking member 48 is positioned in the housing position
at which the roller 69 is retracted inside the vertical stile 12d. In the clutch mechanism
28, the flank face 58b of the driving member 58 is positioned on the upper side of
the driving pin 60.
[0062] At the time of closing the sliding door 12 from the abovementioned state, for example,
the operation handle 29 that is positioned at the 180° position is pressed and the
sliding door 12 is slid toward the closed position. As a result, as illustrated in
FIG. 7(B), the lock pin 44 enters the lock opening 42c. In that state, there remains
a certain gap in between the outside depth face 46 of the vertical stile 12d and the
inside depth face 47 of the vertical frame 14d.
[0063] Subsequently, the operation handle 29 is turned in the closing direction from the
180° position. As a result, the interlocking member 32 moves down and the driving
member 58 too moves down accompanying the interlocking member 32, and the flank face
58b makes sliding contact with the driving pin 60. At that time, the flank face 58b
gets subjected to the pressing force from the driving pin 60, and the driving member
58 moves in the direction away from the driving pin 60 against the biasing force of
the torsion coil spring 84 (see FIG. 8(A)). That is, the driving member 58 not only
includes a clutch structure for connecting the interlocking member 32 and the opening
action supporting mechanism 26 at the time of turning the operation handle 29 in the
opening direction, but also contains a unidirectional transmission structure for maintaining
the disconnected state at the time of turning the operation handle 29 in the closing
direction where the downward movement of the interlocking member 32 is not transmitted
to the opening action supporting mechanism 26 due to the movement of the driving member
58 in the direction away from the driving pin 60 by the pressing force of the driving
pin 60. As a result, the driving member 58 does not interfere with the turning of
the operation handle 29 in the closing direction, and a smooth handle operation can
be performed. Moreover, at the time of closing the sliding door 12, it becomes possible
to avoid a situation in which the opening action supporting mechanism 26 operates
in conjunction with the turning of the operation handle 29 in the closing direction,
and thus the housing position of the kicking member 48 is reliably maintained.
[0064] When the operation handle 29 is turned to the 86° position in the closing direction,
the flank face 58b of the driving member 58 completely overleaps the driving pin 60.
As a result, as illustrated in FIG. 8(B), due to the biasing force of the torsion
coil spring 84, the driving member 58 returns to the initial position that overlaps
in the lower portion of the driving pin 60 in the same manner as the 0° position.
[0065] During the turning action of the operation handle 29; in the lock mechanism 22, the
drawing member 42 moves down during the movement of the operation handle 29 from the
180° position toward the closing direction. In the present embodiment, the drawing
piece 42a of the drawing member 42 starts getting hooked against the head portion
44a of the lock pin 44 at a position such as the 96° position that is just before
the 90° position illustrated in FIG. 8(A). That is, the locking action of the lock
mechanism 22 starts. As a result, since the head portion 44a of the lock pin 44 moves
along the tilt of the drawing piece 42a, the sliding door 12 is gradually drawn in
the direction approaching the vertical frame 14d due to the lock pin 44. Subsequently,
when the operation handle 29 is again turned to the 0° position, the head portion
44a of the lock pin 44 again engages with the drawing member 42 (see FIG. 42(A)),
and the lock mechanism 22 gets locked. As a result, the sliding door 12 gets locked
with respect to the frame member 14, and the vertical stile 12d becomes closely attached
to the vertical frame 14d via a predetermined tight material. With that, the closing
action of the sliding door 12 reaches completion.
[0066] In this way, in the opening section device 11, at the time of locking the lock mechanism
22 from the unlocked state, the opening action supporting mechanism 26 does not operate.
For that reason, a defect in which the sliding door 12 is kicked during the locking
of the lock mechanism 22 is prevented from occurring. Moreover, in the opening section
device 11, when turned in the opening direction as well as in the closing direction,
the operation handle 29 moves within the turning range from the 0° position to the
180° position. Hence, the operation handle 29 never overhangs from the contour range
of the sliding door 12. For that reason, the operation handle 29 never interferes
with the frame member 14.
[0067] Meanwhile, the present invention is not limited to the embodiment described above,
and can be freely modified without deviating from the scope thereof.
[0068] In the embodiment describe above, the configuration is explained in which the interlocking
member 32 is configured by linking the linking member 38, the interlocking lever 40,
and the coupling member 41. Alternatively, for example, the interlocking member 32
can be configured using a single component or two components. However, as described
above, when the interlocking member 32 is configured using the combination of the
linking member 38 pertaining to the operation mechanism 24; the interlocking lever
40 pertaining to the lock mechanism 22; and the coupling member 41 pertaining to the
opening action supporting mechanism 26 and the clutch mechanism 28; for example, in
the case of implementing the interlocking member 32 in an opening section device not
requiring the opening action supporting mechanism 26, it becomes easily possible to
omit the opening action supporting mechanism 26 and the clutch mechanism 28, thereby
enabling achieving a high degree of general versatility.
[0069] In the embodiment described above, the configuration is explained in which the interlocking
member 32 moves up when the operation handle 29 is turned in the opening direction
and moves down when the operation handle 29 is turned in the closing direction. However,
alternatively, the up-and-down relationship can be reversed.
[0070] In the embodiment described above, the configuration is explained in which the lock
mechanism 22 and the opening action supporting mechanism 26 can be simultaneously
operated. Alternatively, the opening action supporting mechanism 26 and the lock mechanism
22 can be configured to be separately operable; or the lock mechanism 22 can be omitted.
[0071] In the embodiment described above, the configuration is explained in which the upward
movement and the downward movement of the interlocking member 32 occurs in conjunction
with the turning of the operation handle 29. Alternatively, the operation mechanism
24 can be electric equipment having a motor, or can be a hand operating device in
which the interlocking member 32 is moved up and down using some other component such
as a lifting lever instead of using the operation handle 29.
[0072] In the embodiment described above, the opening section device 11 is a fitting having
an inner sash structure in which the sliding door 12 slides at the room side of the
fixed door 16. Alternatively, the opening section device 11 can have an outer sash
structure in which the sliding door 12 slides at the outdoor side of the fixed door
16. Even when the external sash structure is adapted, the operation handle 29 is retained
at the 180° position after the end of the actions of the opening action supporting
mechanism 26. Hence, when the sliding door 12 is completely open, the operation handle
29 is prevented from interfering with the meeting stile (the vertical stile 16d) of
the fixed door 16, thereby enabling achieving maximization of the opening dimensions
of the sliding door 12.
[0073] In the embodiment described above, the fitting is configured with the sliding door
12 of the single sliding type as the door body whose opening action is supported by
the opening action supporting device 10. Alternatively, the opening section device
11 can be used also in doors and windows having various sliding structures, such as
in a double sliding door in which, for example, two sliding doors 12 are disposed
in a double-slidable manner, or in a window disposed at a position from which people
enter and exit. Moreover, the door body whose opening action is supported by the opening
action supporting mechanism 26 can be, for example, a door or a horizontal pivoted
window that is different than a sliding door. In that case, it is sufficient to vary
the installation direction of the opening action supporting mechanism 26, and the
operation mechanism 24 can be disposed in a horizontal stile instead of a vertical
stile. Meanwhile, when a door body does not have a stile structure, the opening action
supporting device 10 can be disposed with respect to the face bar or the aggregate
constituting the door body.
[0074] According to the present invention, it becomes possible to enhance the operability
at the time of opening and closing a door body, and also to enhance the general versatility
of the operation mechanism and the opening action supporting mechanism.
[0075] Although the invention has been described with respect to specific embodiments for
