Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the case of a furniture with, for example, a large shoji screen, since the weight of the shoji screen increases, when the shoji screen is moved toward the open position, the shoji screen may be inclined with respect to the frame body. In a state where the shoji screen is inclined with respect to the frame body, the gap between the frame body and the shoji screen will be different vertically, so not only the appearance quality will be impaired, but there is also a concern that the opening and closing operability of the shoji screen will be impaired by affecting the operation of the link mechanism. In particular, immediately after the shoji screen is moved toward the open position, since the gap between the vertical frame and the vertical stile is small, the change in its width becomes significant.

[0005] In view of the above circumstances, an object of the present invention is to provide a furniture that can prevent the shoji screen from tilting when the shoji screen is moved toward the open position.

Means for Solving the Problems

[0006] To achieve the above object, the furniture according to the present invention includes a frame body configured with upper and lower horizontal frames and left and right vertical frames, and a shoji screen configured with upper and lower horizontal stiles and left and right vertical stiles. The shoji screen is supported by the link mechanism provided between the horizontal frame and the horizontal stile so as to be openable with respect to the frame body such that one of the vertical stiles protrudes in the out-of-plane direction. A first regulating mechanism and a second regulating mechanism are provided between the frame body and the shoji screen and contact each other to regulate the movement of the shoji screen to the outdoor side with respect to the frame body. The first regulating mechanism comes into contact at least when the shoji screen is disposed at the closed position with respect to the frame body, and the contact state is released when the shoji screen moves toward the open position. The second regulating mechanism comes into contact when the first regulating mechanism is in the contact state, and the contact state is released after the contact state of the first regulating mechanism is released when the shoji screen moves toward the open position.

Effects of the Invention

[0007] According to the present invention, when the shoji moves toward the open position, the second regulating mechanism is in the contacting state, and the movement of the shoji toward the outdoor side with respect to the frame body is regulated. Therefore, the situation where the shoji tilts with respect to the frame body is prevented, and there is no concern that the appearance quality is impaired or the opening and closing operability of the shoji is impaired.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, a preferred embodiment of the fitting according to the present invention will be described in detail with reference to the accompanying drawings. For convenience, the terms "prospective direction" and "search direction" may be used hereinafter. The prospective direction is the direction along the depth of the fitting, as indicated by arrow A in the figure. A surface along the prospective direction may be referred to as a prospective surface. The search direction is the direction along the vertical direction perpendicular to the prospective direction in the case of an object extending along the horizontal direction such as a horizontal frame. In the case of an object extending along the vertical direction such as a vertical frame, the search direction is the direction along the horizontal direction perpendicular to the prospective direction. A surface along the search direction may be referred to as a search surface.

[0010] Figs. 1 to 3 show a fitting which is an embodiment of the present invention. The fitting exemplified here is a so-called vertically sliding out window configured such that the shoji 20 is pushed open toward the outdoor side with respect to the frame body 10.

[0011] The frame body 10 is configured by forming a four-sided frame with upper and lower horizontal frames 11, 12 and left and right vertical frames 13, 14. The horizontal frames 11, 12 and vertical frames 13, 14 constituting the frame body 10 are each composed of a metal frame portion 11M, 12M, 13M, 14M extruded from a metal such as an aluminum alloy and a resin frame portion 11P, 12P, 13P, 14P extruded from a resin. The resin frame portions 11P, 12P, 13P, 14P are provided so as to cover the portions of the metal frame portions 11M, 12M, 13M, 14M facing the interior of the room. The shoji 20 is configured by supporting a panel 25 such as double glazing inside a frame body formed by assembling upper and lower horizontal frames 21, 22 and left and right vertical frames 23, 24. The horizontal frames 21, 22 and vertical frames 23, 24 are also each composed of a metal frame portion 21M, 22M, 23M, 24M formed from a metal such as an aluminum alloy and a resin frame portion 21P, 22P, 23P, 24P formed from a resin. The resin frame portions 21P, 22P, 23P, 24P are provided so as to cover the portions of the metal frame portions 21M, 22M, 23M, 24M facing the interior of the room.

[0012] In the illustrated example, a vertical sliding window is exemplified which is configured to open while rotating such that a vertical frame located on the right side (hereinafter referred to as "door end frame 24" when distinguishing) with respect to a vertical frame located on the left side (hereinafter referred to as "suspension end frame 23" when distinguishing) as viewed from the indoor side protrudes toward the outdoor side. Note that as a vertical sliding window, it is also possible to configure it with a left-right reverse structure such that the left side is the door end as viewed from the indoor side. When configuring a vertical sliding window with a left-right reverse structure, the components described below may be provided symmetrically.

[0013] On the metal frame portions 11M and 12M of the upper and lower horizontal frames 11 and 12 and the metal frame portions 13M and 14M of the vertical frames 13 and 14, contact fin portions 15 are provided at portions on the indoor side on the prospective surfaces on the inner peripheral side. The contact fin portions 15 extend in the prospective direction toward the inner periphery. A seal member 16 that forms a continuous series around the perimeter is attached to the extending edge portions of the respective contact fin portions 15 on the surface facing the outdoor side.

[0014] Link mechanisms 30, each referred to as a friction stay, are provided between the upper horizontal frames 11 and 12 and the upper vertical frames 21 and 22 and between the lower horizontal frames 11 and 12 and the lower vertical frames 21 and 22. The link mechanisms 30 support the shoji 20 so as to be openable and closable with respect to the frame body 10. In the present embodiment, the link mechanism 30 is configured to include a slide base 40, a first link member 50, a second link member 60, a third link member 70, and a fourth link member 80. The slide base 40, the first link member 50, the second link member 60, the third link member 70, and the fourth link member 80 are each configured as elongated members having a width smaller than the dimension along the prospective direction of the vertical frames 21 and 22 and a length smaller than the dimension along the longitudinal direction of the vertical frames 21 and 22.

[0015] The slide base 40 is to be attached along the longitudinal direction to the prospective surface on the inner peripheral side of the horizontal frames 11 and 12. A slider 90 is provided on this slide base 40. The slider 90 has a short length with respect to the slide base 40 and is arranged so as to be movable along the longitudinal direction of the slide base 40. The first link member 50 is configured to have a dimension shorter than the slide base 40 and longer than the slider 90, and one end portion thereof is rotatably supported at one end portion of the slide base 40 via a first support shaft 51 extending vertically. The one end portion of the slide base 40 that supports the first link member 50 is the end portion on the side closer to the door end frame 24 when the shoji 20 is disposed at the closed position. The second link member 60 is configured to have substantially the same length as the slider 90, and one end portion thereof is rotatably supported at a portion substantially at the center of the slider 90 via a second support shaft 61 extending vertically. The third link member 70 is to be attached along the longitudinal direction to the prospective surface on the outer peripheral side of the horizontal frames 21 and 22 and is configured to have substantially the same length as the first link member 50. One end portion of this third link member 70 is rotatably supported at the other end portion of the second link member 60 via a third support shaft 71 extending vertically. At a portion substantially at the center in the longitudinal direction of the third link member 70, the other end portion of the first link member 50 is rotatably supported via a fourth support shaft 52 extending vertically. The fourth link member 80 has a length approximately half that of the third link member 70, and one end portion thereof is rotatably supported at the slider 90 via the second support shaft 61 together with the above-described second link member 60. The other end portion of the fourth link member 80 is rotatably supported at an intermediate portion of the first link member 50 via a fifth support shaft 81 extending vertically.

[0016] The link mechanism 30 having the above-described configuration supports the shoji 20 so as to be openable and closable with respect to the frame body 10 by attaching the slide base 40 to the prospective surfaces on the inner peripheral sides of the horizontal frames 11 and 12 respectively and attaching the third link member 70 to the prospective surfaces on the outer peripheral sides of the horizontal frames 21 and 22 respectively. As is apparent from the figure, the third link member 70 is arranged so as to be close to the suspension frame 23, and the slide base 40 is arranged so as to be close to the vertical frame 13.

[0017] In this link mechanism 30, as shown in FIG. 4, when the shoji 20 is disposed at the closed position with respect to the frame body 10, the third link member 70 is disposed at a position facing the slide base 40, and the first link member 50, the second link member 60, and the fourth link member 80 are disposed so as to overlap each other between the slide base 40 and the third link member 70. At this time, the shoji 20 is in a locked state by the locking device 100 provided between the door end frame 24 and the vertical frame 14, and is maintained at the closed position with respect to the frame body 10.

[0018] From the above state, when the locking device 100 is unlocked via the operation handle 1 and the shoji 20 is operated so that the door end frame 24 protrudes outside the room, as shown in FIG. 5, the third link member 70 rotates about the third support shaft 71 so that the other end protrudes to the outside of the room, and then, as the third link member 70 rotates, the first link member 50 rotates about the first support shaft 51 so that the other end protrudes to the outside of the room. When the third link member 70 and the first link member 50 rotate, the slider 90 moves to one end side of the slide base 40, and the second link member 60 and the fourth link member 80 rotate so that their respective other ends protrude to the outside of the room. As a result, in the vertical sliding window, the shoji 20 rotates about the hanging frame 23 side with the hanging frame 23 sliding to one end side of the slide base 40, and the shoji 20 opens in a state of protruding substantially at a right angle to the outside of the room with respect to the frame body 10.

[0019] Here, in the shoji 20 that is supported by the frame body 10 via the link mechanism 30 so as to be openable and closable, even when the shoji 20 is disposed at the closed position, it is difficult to maintain the position of the shoji 20 with respect to the frame body 10 on the hanging side. Further, depending on the weight of the shoji 20, there is a concern that the shoji 20 may tilt when it starts to move toward the open position. Therefore, in the fitting of the present embodiment, a pulling mechanism (first regulating mechanism) 110 and a sag prevention mechanism (second regulating mechanism) 120 are provided between the vertical frame 13 and the hanging frame 23.

[0020] The attracting mechanism 110 is configured such that when the shoji 20 is disposed at the closed position, it comes into contact with each other and restricts the shoji 20 from moving to the outdoor side with respect to the frame body 10. As shown in FIG. 1, the attracting mechanism 110 is provided at three positions, namely, the upper part, the middle part, and the lower part of the shoji 20. As shown in FIG. 6, the frame-side attracting piece 111 is provided on the prospective surface on the inner peripheral side of the vertical frame 13, and the frame-side attracting piece 112 is provided on the prospective surface on the outer peripheral side of the hanging base frame 23, thereby constituting the attracting mechanism 110. The frame-side attracting piece 111 protrudes from the prospective surface of the vertical frame 13 toward the inner peripheral side, and has a frame-side support surface 111a at the corner located on the inner peripheral side and on the indoor side. The frame-side support surface 111a is a plane along the vertical direction that is inclined so as to gradually become the inner peripheral side toward the outdoor. The frame-side attracting piece 112 protrudes from the prospective surface of the hanging base frame 23 toward the outer peripheral side, and has a frame-side support surface 112a at the corner located on the outer peripheral side and on the outdoor side. The frame-side support surface 112a is a plane along the vertical direction that is inclined so as to gradually become the inner peripheral side toward the outdoor, and is provided so as to be substantially parallel to the frame-side support surface 111a.

[0021] As shown in FIG. 6(a), these frame-side attracting piece 111 and frame-side attracting piece 112 are provided such that the frame-side support surface 111a and the frame-side support surface 112a come into contact with each other when the shoji 20 is disposed at the closed position. The position where the frame-side support surface 111a and the frame-side support surface 112a come into contact is a portion on the indoor side with respect to the rotation axis center when the shoji 20 starts to move from the closed position toward the open position. The rotation axis center when the shoji 20 starts to move toward the open position is, as described above, the axis center when the other end of the third link member 70 rotates so as to be at the protruding position protruding to the outdoor side, and substantially coincides with the axis center of the third support shaft 71. Hereinafter, this rotation axis center is referred to as the initial movement axis center C.

[0022] The sag prevention mechanism 120 is configured such that when the shoji 20 is in the closed position and in the initial stage of starting to move from the closed position toward the open position, the components come into contact with each other to restrict the shoji 20 from moving to the outdoor side with respect to the frame body 10. As shown in FIG. 1, the position where the sag prevention mechanism 120 is provided is further above the draw-in mechanism 110 arranged at the uppermost position. As shown in FIG. 6(a), in the present embodiment, the sag prevention mechanism 120 is configured by providing a roller 121 on the prospective surface on the inner peripheral side of the vertical frame 13 and a contact block 122 on the prospective surface on the outer peripheral side of the suspension base frame 23.

[0023] The roller 121 is attached via a bracket 123 so as to protrude from the vertical frame 13 toward the inner peripheral side and is rotatable about an axis along the vertical direction. The contact block 122 protrudes from the suspension base frame 23 toward the outer peripheral side and has a contact surface 122a at a corner located on the outer peripheral side and the outdoor side. The contact surface 122a is a plane along the vertical direction that is inclined so as to gradually become the inner peripheral side toward the outdoor. These roller 121 and contact block 122 are provided such that the contact surface 122a contacts the circumferential surface of the roller 121 when the shoji 20 is in the closed position. The circumferential surface of the roller 121 with which the contact block 122 contacts is a portion that is on the indoor side of a virtual vertical plane along the finding direction including the axis of the roller 121 and on the inner peripheral side of a virtual vertical plane along the prospective direction including the axis of the roller 121. As is clear from the figure, the contact position between this roller 121 and the contact block 122 is on the outdoor side of the contact position between the frame-side draw-in piece 111 and the frame-side draw-in piece 112 in the draw-in mechanism 110, and is closer to the initial movement axis C than the contact position between the frame-side draw-in piece 111 and the frame-side draw-in piece 112. In particular, in the illustrated example, the initial movement axis C is located on the circumferential surface of the roller 121, and the roller 121 and the contact block 122 are set to contact at the initial movement axis C.

[0024] In the fitting configured as described above, when the shoji 20 is arranged at the closed position, as shown in Fig. 6(a), the frame-side attracting piece 111 and the stile-side attracting piece 112 of the attracting mechanism 110 abut against each other, and the roller 121 and the contact block 122 of the sag prevention mechanism 120 are in contact with each other. Therefore, even when an external force that pulls the shoji 20 toward the outdoor side due to the wind pressure (negative pressure) outdoors acts, the shoji 20 is prevented from moving with respect to the frame body 10, and the seal member 16 is maintained in a state of abutting against the four circumferences of the shoji 20. Thereby, it becomes possible to ensure the airtightness and watertightness in the indoor-outdoor direction.

[0025] When the shoji 20 is moved in the opening direction from the above-described state, as shown in Fig. 6(b), the contact state between the frame-side attracting piece 111 and the stile-side attracting piece 112 is released. However, regarding the sag prevention mechanism 120, as long as the shoji 20 rotates about the starting axis C, the contact surface 122a of the contact block 122 is maintained in a state of being in contact with the circumferential surface of the roller 121. As described above, the contact position between the circumferential surface of the roller 121 and the contact block 122 is on the indoor side of the virtual vertical plane along the finding direction including the axis of the roller 121. Therefore, the roller 121 and the contact block 122 prevent the shoji 20 from moving to the outdoor side with respect to the frame body 10, and it becomes possible to prevent the shoji 20 from tilting due to its own weight. Thereby, the gap between the frame body 10 and the shoji 20 becomes uniform in the vertical direction, and there is no possibility of impairing the appearance quality or affecting the operation of the link mechanism 30.

[0026] In the above-described embodiment, a composite type having a metal frame portion formed of metal and a resin frame portion formed of resin as the horizontal frame and the vertical frame constituting the frame body is applied, but the frame body does not necessarily have to be of the composite type. Similarly, a composite type having a metal stile portion and a resin stile portion is applied as the horizontal stile and the vertical stile constituting the shoji, but the present invention is not limited to this. Further, in the above-described embodiment, as the link mechanism, an example is given of a configuration including a slide base 40, a first link member 50, a second link member 60, a third link member 70, and a fourth link member 80, but the configuration of the link mechanism is not limited to this. Furthermore, in the above-described embodiment, a second regulation mechanism including a roller and a contact block is exemplified, but it is not always necessary to apply a roller. When a roller is applied, in the above-described embodiment, the roller is provided on the frame body side, but it is also possible to configure it to provide the roller on the shoji side. Additionally, although the initial movement axis is set on the circumferential surface of the roller, the present invention is not limited to this. Furthermore, in the above-described embodiment, a plurality of first regulation mechanisms are provided, but it is not necessary to provide a plurality of first regulation mechanisms.

[0027] As described above, the fitting according to the present invention includes a frame body configured to have upper and lower horizontal frames and left and right vertical frames, and a shoji configured to have upper and lower horizontal stiles and left and right vertical stiles, and is a fitting in which the shoji is supported so as to be openable with respect to the frame body such that one of the vertical stiles protrudes in the out-of-plane direction by a link mechanism provided between the horizontal frame and the horizontal stile, and includes a first regulation mechanism and a second regulation mechanism provided between the frame body and the shoji and configured to regulate the movement of the shoji to the outdoor side with respect to the frame body by coming into contact with each other. The first regulation mechanism comes into contact at least when the shoji is disposed at the closed position with respect to the frame body, and the contact state is released when the shoji moves toward the open position. The second regulation mechanism comes into contact when the first regulation mechanism is in the contact state, and the contact state is released after the contact state of the first regulation mechanism is released when the shoji moves toward the open position. According to the present invention, when the shoji moves toward the open position, the second regulating mechanism is in the contact state, and the movement of the shoji toward the outdoor side with respect to the frame is restricted. Therefore, the situation where the shoji tilts with respect to the frame is prevented, and there is no concern that the appearance quality is impaired or the opening / closing operability of the shoji is impaired.

[0028] Further, in the present invention, in the fitting described above, the first regulating mechanism and the second regulating mechanism are respectively provided between the vertical frame and the other of the vertical muntins, and the second regulating mechanism is in the contact state at a position above the first regulating mechanism. According to the present invention, since the second regulating mechanism is provided in the upper part of the vertical frame and the vertical muntin, it is possible to prevent the shoji from tilting more efficiently.

[0029] Further, in the present invention, in the fitting described above, the shoji moves toward the open position while rotating around a rotation axis along the vertical direction, and the first regulating mechanism and the second regulating mechanism are respectively provided between the vertical frame and the other of the vertical muntins, and the second regulating mechanism is in the contact state at a position closer to the rotation axis than the first regulating mechanism. According to the present invention, by providing the second regulating mechanism so that the distance from the rotation axis is smaller than that of the first regulating mechanism, the contact state of the second regulating mechanism can be released after the contact state of the first regulating mechanism is released.

[0030] Further, in the present invention, in the fitting described above, the shoji moves toward the open position while rotating around a rotation axis along the vertical direction, and the second regulating mechanism includes a roller disposed on either the vertical frame or the vertical muntin in a state rotatable around an axis along the vertical direction, and a contact block disposed on the other of the vertical frame and the vertical muntin in a state of contacting the peripheral surface of the roller. According to the present invention, since the roller contacting the contact block rotates when the shoji moves toward the open position, there is no concern that the opening / closing operability of the shoji is impaired.
