Abstract
Description
Technical Field
[0001] The present invention relates to a fitting provided with a shoji door that can be opened and closed on the inner peripheral side of a frame body.
Background Art
[0002] There is a fitting provided with a shoji door that can be opened and closed on the inner peripheral side of a frame body, and is provided with an outdoor handle so that it can be temporarily opened and closed from the outside. Since the outdoor handle is for temporary use, unlike the indoor handle, it is provided along the longitudinal direction of the stile of the shoji door so as not to be conspicuous. When this outdoor handle is rotated from the longitudinal direction so as to point to the outside, the lock device can be operated to open the shoji door (Patent Document 1, Patent Document 2).

Summary of the Invention
Problems to be Solved by the Invention
[0004] Some fittings provided with a shoji door that can be opened and closed on the inner peripheral side of a frame body are provided with a full / half open device. The full / half open device normally restricts the opening degree of the shoji door to a half-open state where people cannot pass through, and by performing a predetermined operation, the restriction is released to enable full opening.
[0005] Opening the shoji door by operating the outdoor handle is assumed to be, for example, when the fire brigade enters, so it must be possible for people to pass through. It is desirable that not only the lock is released by one operation of the outdoor handle, but also the full / half open device can be released.
[0006] In the fitting described in Patent Document 1, even if the exterior handle is operated, only the lock is released, and the full-half-open device is not released. In the fitting described in Patent Document 2, the exterior handle is installed on the bottom frame, while the full-half-open device is installed on the vertical frame, so a corner drive or switching hardware is required to change the direction of operation. The switching hardware is used to branch and transmit the movement of the exterior handle to the unlocking device and the full-half-open device, and by providing a long hole, the exterior handle does not move in conjunction with the operation of the interior handle, and the unlocking and full-half-open devices of the interior handle are switched to the fully open state only when the exterior handle is operated. The provision of such a corner drive or switching hardware makes the structure complicated.
[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a fixture that can activate both the locking device and the full / half-open device with a simple structure by operating the outdoor handle once. [Means for solving the problem]
[0008] In order to solve the above-described problems and achieve the object, a fitting according to the present invention is a fitting provided with a shoji door that can be opened and closed on the inner peripheral side of a frame body, and includes a locking device that locks the shoji door in a closed state with respect to the frame body, a full / half opening device that restricts the possible opening degree of the shoji door to a half-open state, and a lock release device that releases the locked state of the shoji door by the locking device from the outdoor side. The lock release device includes a base member provided with a vertical stile of the shoji door or a vertical frame of the frame body as an attachment target member, an outdoor handle that rotates with respect to the base member and is provided so as to be rotatable from the outdoor side, a slide piece that is driven by the rotation operation of the outdoor handle and slides in the longitudinal direction of the attachment target member, a first bar provided along the longitudinal direction that switches between locking and unlocking of the shoji door by the locking device, and a second bar provided along the longitudinal direction that switches the possible opening degree of the shoji door by the full / half opening device between a half-open state and a fully open state. The slide piece presses and displaces the first bar by the sliding operation to release the lock by the locking device, and the second bar is fixed to the slide piece and slides together with the slide piece to release the restriction of the half-open state by the full / half opening device and enable full opening.
Effect of the Invention
[0009] In the fitting according to the present invention, the lock release device is provided on the vertical stile or the vertical frame, and a mechanism for converting the operation direction between the lock release device, the locking device, and the full / half opening device becomes unnecessary. Therefore, both the locking device and the full / half opening device can be operated with a simple structure by one operation of the outdoor handle.

Embodiments for Carrying Out the Invention
[0011] Hereinafter, embodiments of the fitting according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by this embodiment.
[0012] Hereinafter, for the sake of convenience, the terms "prospective direction" and "search direction" may be used. The prospective direction is the direction along the depth of the fitting. A surface or wall along the prospective direction may be referred to as a prospective surface or prospective wall. The search direction is, in the case of those extending along the horizontal direction such as the upper frame, lower frame, upper vertical frame, lower vertical frame, etc., the vertical direction orthogonal to the prospective direction. In the case of those extending along the vertical direction such as the vertical frame, vertical vertical frame, etc., the horizontal direction orthogonal to the prospective direction is referred to as the search direction. A surface or wall along the search direction may be referred to as a search surface or search wall.
[0013] FIG. 1 is an external view of a fitting 10 according to an embodiment of the present invention as seen from the outdoor side. The fitting 10 is an outward-opening window and has a frame body 12 provided at a building opening and a shoji 14 provided on the inner peripheral side of the frame body 12. The fitting 10 may be a sliding window or the like. The shoji 14 is openable and closable on the outdoor side with respect to the frame body 12. In this embodiment, it is assumed that the left side opens and closes based on the hinge or the like on the right side in FIG. 1.
[0014] The shoji screen 14 is constructed by disposing a panel 24 inside a frame body 22, which is constructed by assembling an upper frame 16, a lower frame 18, and left and right vertical frames 20 all around. The panel 24 is, for example, made of glass. The frame body 12 is constructed by assembling an upper frame 26, a lower frame 28, and left and right vertical frames 30 all around. Each frame material and each frame material is a metal such as an aluminum alloy, a resin material, or a composite material of these, and each is an extruded material configured to have a substantially uniform cross-sectional shape along its entire length. In the following explanation, unless otherwise specified, the vertical frame 30 and vertical frame 20 refer to the left side of the pair in FIG. 1.
[0015] Near the left edge of the shoji screen 14, there is an indoor handle 32 on the indoor side, and an outdoor handle 34 on the outdoor side. Between the vertical frame 30 and the vertical stile 20, there are provided a locking device 36, a half-opening device 38, and an unlocking device 40.
[0016] FIG. 2 is a diagram showing the vertical frame 30 and the vertical frame 20. The vertical frame 30 shows the inner peripheral side projection portion, and the vertical frame 20 shows the portion facing the inner peripheral side projection portion of the vertical frame 30, and are illustrated side by side to make the correspondence easier to understand. The outer peripheral cover of the vertical frame 30 is omitted so that the locking device 36, the half-opening device 38, and the unlocking device 40 can be seen. In FIG. 2, the linkage bar (first bar) 42 is shown with a dark dot background for easy identification, and the connecting bar (second bar) 76 and its attached parts are shown with a light dot background. The longitudinal direction (here, the vertical direction) of the vertical frame 30 and the vertical frame 20 is the X direction, one side (here, the lower side) is the X1 direction, and the other side (here, the upper side) is the X2 direction. The indoor handle 32 is on the X2 side of the half-opening device 38. The half-opening device 38 is on the X2 side of the unlocking device 40.
[0017] The locking device 36 locks the shoji 14 in the closed state with respect to the frame body 12, and has a linkage bar 42 extending in the X direction with respect to the vertical stile 20 and a lock receiving portion 46 provided on the prospective surface of the vertical frame 30. Pins 42a and 42b are provided on the linkage bar 42 so as to project to the outer peripheral side at positions slightly apart from each other. The pin 42a is on the X2 side of the pin 42b.
[0018] The linkage bar 42 is configured to move up and down in conjunction with the operation of the indoor handle 32. When the indoor handle 32 is in the closed position, it is relatively on the X2 side, and when it is in the open position, it is displaced relatively to the X1 side. The pin 42a is between the full / half-open device 38 and the unlocking device 40. When the linkage bar 42 is on the X2 side, it engages with the lock receiving portion 46 to lock the shoji 14 in the closed state, and when the linkage bar 42 is on the X1 side, it separates from the lock receiving portion 46 to release the lock and make the shoji 14 in an openable / closable state.
[0019] The full / half-open device 38 switches the possible opening degree of the shoji 14 between the fully open state and the half-open state, and normally regulates it to the half-open state. The full / half-open device 38 has a full / half-open device base portion 48, a full / half-open device slide piece 50, an angle regulating arm 52, a guide member 54, and a full / half-open device receiving portion 56. The full / half-open device receiving portion 56 is provided on the finding surface of the vertical stile 20, and the rest are provided on the vertical stile 20. The full / half-open device base portion 48 is fixed to the vertical stile 20 and is not interlocked with the linkage bar 42. The guide member 54 is fixed to the full / half-open device base portion 48.
[0020] The X2-side end of the angle regulating arm 52 is pivotally supported on the full / half-opening device slide piece 50 by a shaft 52a, and is rotatable inward with respect to the shaft 52a as shown by the arrow in Fig. 2. A pin 52b that slightly protrudes to the outer peripheral side is provided at the X1-side end of the angle regulating arm 52. The full / half-opening device slide piece 50 is biased toward the X2 side by a spring (not shown). The full / half-opening device slide piece 50 is provided with an interlocking protrusion 50a that protrudes to the outdoor side. The interlocking protrusion 50a protrudes to the outdoor side more than the full / half-opening device base portion 48 and the guide member 54. A guide opening 54a for guiding the shaft 52a is formed in the guide member 54. The full / half-opening device receiving portion 56 is long in the X direction, and a guide groove 56a that opens downward is formed at the center. In a state where the full / half-opening device slide piece 50 and the angle regulating arm 52 are displaced toward the X2 side by a spring (the state in Fig. 2), the pin 52b enters the lower end opening of the guide groove 56a.
[0021] By operating the indoor handle 32, the lock of the locking device 36 is released, and the shoji 14 can open to the outdoor side with respect to the frame body 12. At this time, the angle regulating arm 52 moves to the X2 side with the pin 52b at the lower end guided by the guide groove 56a, and further rotation is restricted by abutting against the X2-side end of the guide groove 56a, and the shoji 14 is restricted in the half-open state. In such a half-open state, the opening degree of the shoji 14 is, for example, about 10 cm, and ventilation is possible, but it is possible to prevent people from passing through inadvertently.
[0022] Note that the pin 42b receives an action from the unlocking device 40. However, when the linkage bar 42 is displaced in the X1 direction by operating the indoor handle 32, the pin 42b only moves away from the unlocking device 40 and does not act on the unlocking device 40 from the pin 42b. The interlocking protrusion 50a receives an action from the unlocking device 40 via a connecting bar 76 and an action piece 82, which will be described later.
[0023] In such a fitting 10, although it is basically not assumed that people pass from the indoor side to the outdoor side, a unlocking device 40 is provided so that people can pass from the outdoor side to the indoor side temporarily, and the shoji 14 can be fully opened. "Temporarily" is assumed, for example, during the emergency entry of the fire brigade, but it does not prevent the use by construction workers, cleaning workers, etc. with the permission of the administrator. Also, although not usually assumed, when it is necessary to fully open the shoji 14 from the indoor side, the dedicated knob may be configured to be detachable from the indoor side with respect to the full / half-open device slide piece 50, and the dedicated knob may be pressed to the X1 side so that the pin 52b can be detached from the guide groove 56a.
[0024] Next, the unlocking device 40 will be described. FIG. 3 is a perspective view of the unlocking device 40 as viewed from the outer peripheral side. In FIG. 3, a part around the unlocking device 40 is shown by a virtual line. FIG. 4 is a perspective view of the unlocking device 40 as viewed from the inner peripheral side. FIG. 5 is an exploded perspective view of the unlocking device 40. Each component shown in FIG. 5 is in the same orientation as in FIG. 4. FIG. 6 is a cross-sectional view of the vertical frame 20 in the vicinity of the unlocking device 40. The unlocking device 40 releases the locked state of the shoji 14 by the locking device 36 from the outdoor side, and at the same time acts on the full / half-open device 38 so that the shoji 14 can be fully opened.
[0025] The unlocking device 40 includes a base member 58, a lever member 60, and a slide piece 62. The base member 58, the lever member 60, and the slide piece 62 are formed of a metal such as stainless steel, for example.
[0026] The base member 58 is provided with the vertical frame 20 of the shoji 14 as a mounting target member. Bent-shaped vertical walls 58e are formed on the X1 side and the X2 side of the flat plate 58g of the plate-shaped member that is slightly longer in the X direction. A bent-shaped vertical wall 58f is formed on the indoor side. Further, the ends on the X1 side and the X2 side are bent at the tips of the vertical walls 58e to form a crank shape, thereby forming the fixing pieces 58a. By screwing the screw 64 through the screw hole of the fixing piece 58a into the vertical frame 20, the unlocking device 40 is fixed to the vertical frame 20. The vertical wall 58e serves as the column part of the base member 58 with respect to the vertical frame 20.
[0027] Three pin holes 581c, 582c, and 583c are formed in the base member 58. The pin hole 581c is approximately at the center in the prospective direction and approximately at the center in the X direction. The pin hole 582c is near the indoor side end and is slightly closer to the X1 side than the center in the X direction. The pin hole 583c is near the X1 side end. The shaft pin 66a is fixed to the pin hole 581c via the center hole 70a and the vertical guide long hole 621d described later. The fixing of each pin is by caulking or press-fitting the tip. The vertical guide pin 66b is fixed to the pin hole 582c via the vertical guide long hole 622d described later. The shaft pin 66a and the vertical guide pin 66b are simply referred to as pins 66a and 66b. The stopper pin 66c is fixed to the pin hole 583c. The shaft pin 66a, the vertical guide pin 66b, and the stopper pin 66c have the same shape. A retaining spring 68 is provided on the stopper pin 66c.
[0028] The vertical wall 58f is lower and inclined compared to the vertical wall 58e, and a gap 58d is secured in which the base member 58 described later can be arranged and displaced. There is no bent portion on the outdoor side of the base member 58, and the lever member 60 described next can be rotationally displaced.
[0029] Regarding the shape of the lever member 60, an explanation will be given based on the posture of the outdoor handle 34 when not in operation (the postures in FIGS. 3, 4, and 5). The lever member 60 is provided so as to rotate with respect to the base member 58, and includes the above-described outdoor handle 34, a rotation center plate 70 having a substantially semicircular shape, and a connecting plate 72 that obliquely connects the rotation center plate 70 and the outdoor handle 34. A center hole 70a through which a shaft pin 66a is inserted is formed at the center of the rotation center plate 70, and the lever member 60 is pivotally supported by the shaft pin 66a and is rotatable. A slightly small pin hole 70b is formed in the rotation center plate 70 at a position near the outdoor side and the X1 side of the center hole 70a. A small horizontal guide pin 74 is fixed to the pin hole 70b in a slightly protruding state.
[0030] The rotation center plate 70 and the connecting plate 72 are continuous plate materials. The outdoor handle 34 is slightly thicker than the rotation center plate 70 and the connecting plate 72 so as to be easy to grip and have appropriate strength. The lever member 60 has a portion of the rotation center plate 70 in contact with and in sliding contact with the inner surface of the flat plate 58g. The flat plate 58g is arranged along the X direction and the prospective direction. Therefore, the lever member 60 and the outdoor handle 34 rotate on a plane along the X direction and the prospective direction. Also, as the outdoor handle 34 rotates, it extends along the X1 direction and the outdoor direction from the rotation center plate 70.
[0031] The connecting plate 72 is a substantially parallelogram, and its outdoor side edge forms a part of the outdoor handle 34. The rotation of the lever member 60 is restricted in the non-operation posture (see FIG. 4) when the corner of the connecting plate 72 abuts against the stopper pin 66c. Also, in this state, the lever member 60 is positioned by a part of the detent spring 68 elastically engaging with a small recess 72a near the corner of the connecting plate 72, and it does not move inadvertently.
[0032] The outdoor handle 34 is provided at the outdoor side edge of the connection plate 72. The outdoor handle 34 is moderately thin so as not to be too conspicuous, but has sufficient strength to withstand manual operation. When not in operation, the outdoor handle 34 extends in the X1 direction along the vertical frame 20 so as not to be too conspicuous. The outdoor handle 34 is located close to the vertical frame 20 so as not to be too conspicuous, but is separated to such an extent that it can be gripped by hand and has a length sufficient for manual gripping.
[0033] The slide piece 62 is driven by the rotation operation of the outdoor handle 34 to slide in the X direction, and has a base slide sliding portion 62a and a bar driving piece 62b. The bar driving piece 62b is bent in two steps from the indoor side and the end closer to X2 of the slide sliding portion 62a and protrudes indoors. A pin 42b is adjacent to the X1 side of the bar driving piece 62b (see FIGS. 2 and 3).
[0034] Two vertical guide long holes 621d and 622d that are long in the X direction and a horizontal guide long hole 62e that is long in the prospective direction are formed in the slide sliding portion 62a. The vertical guide long hole 621d is on the X2 side and the outdoor side relative to the vertical guide long hole 622d. The horizontal guide long hole 62e is on the outdoor side of the vertical guide long hole 621d. The prospective width of the horizontal guide long hole 62e is smaller than the X-direction width of the vertical guide long hole 621d. A shaft pin 66a is inserted through the vertical guide long hole 621d. A vertical guide pin 66b is inserted through the vertical guide long hole 622d. A horizontal guide pin 74 is inserted through the horizontal guide long hole 62e.
[0035] Returning to FIG. 2, the vertical frame 20 is provided such that a connecting bar 76 extends from the vicinity of the X2 side of the unlocking device 40 toward the X2 side. The X1 side end of the connecting bar 76 is fixed to the bar driving piece 62b by a screw with an L-shaped bracket 78. The X2 side end of the connecting bar 76 extends through the outdoor side of the fully and half-opening device 38 and further to the X2 side and is held in a vertically movable manner by a holding member 80. An acting piece 82 protruding toward the indoor side is provided at a portion slightly on the X1 side of the holding member 80 in the connecting bar 76. The acting piece 82 is near the X2 side of the interlocking protrusion 50a and is configured to press and displace the interlocking protrusion 50a when the connecting bar 76 is displaced to the X1 side.
[0036] As shown in FIG. 6, both ends in the prospective direction of the linkage bar 42 are slidably supported by L-shaped slide guides 20a at the indoor side end of the vertical frame 20. An outer peripheral side protruding piece 20b protruding toward the outer peripheral side and an inner peripheral side protruding piece 20c protruding toward the inner peripheral side are formed on the outdoor side finding surface of the vertical frame 20. The outer peripheral side protruding piece 20b is shorter than the inner peripheral side protruding piece 20c and is about 1 / 3 in this embodiment. A rectangular hollow portion 20d long in the prospective direction is provided in the vertical frame 20 on the outdoor side. The outer peripheral side protruding piece 20b, the inner peripheral side protruding piece 20c, and the hollow portion 20d form a continuous outdoor side finding surface.
[0037] A pocket 20e is formed between the indoor side surface of the outer peripheral side protruding piece 20b and the outer peripheral side surface of the hollow portion 20d. A pocket 20f is formed on the indoor side of the tip of the inner peripheral side protruding piece 20c. A pocket 20g is formed on the outer peripheral side surface of the indoor side end of the hollow portion 20d. The pockets 20e, 30f, and 20g are for fixing beads or the like.
[0038] The vertical wall 58e that forms the pillar portion of the base member 58 has an elongated rectangular notch in the indoor and inner peripheral sides in the prospective direction. The notched portion abuts against the pocket 20g, and the non-notched portion abuts against the prospective surface of the vertical frame 20 to ensure stability. The height H1 with respect to the pocket 20g and the height H2 with respect to the vertical frame 20 of the vertical wall 58e are set to be appropriately high. As a result, the flat plate 58g with which the rotation center plate 70 makes sliding contact is arranged at a position shifted to the outer peripheral side so that the outdoor handle 34 does not interfere with the outer peripheral side protruding piece 20b. Therefore, it is not necessary to form a notch in the outer peripheral side protruding piece 20b according to the operating range of the outdoor handle 34, which facilitates construction and is aesthetically suitable.
[0039] FIG. 7 is a diagram showing the operation state of the unlocking device 40. (a) is a diagram showing the non-operating state, (b) is a diagram showing the state where the outdoor handle 34 is at 45 degrees during operation, and (c) is a diagram showing the state where the operation is completed and the outdoor handle 34 is at 90 degrees. FIG. 7 shows the unlocking device 40 as viewed from the inner peripheral side.
[0040] As shown in FIG. 7(a), in the unlocking device 40 in the non-operating state, the outdoor handle 34 extends along the X1 direction. At this time, the slide piece 62 is at the position most biased toward the X2 side within the X-direction width range of the base member 58. The pins 66a and 66b are at the X1-side ends of the vertical guide long holes 621d and 622d. The horizontal guide pin 74 is at the indoor-side end of the horizontal guide long hole 62e. When a force is applied to the outdoor handle 34 in the clockwise direction in FIG. 7 from this state, the recess 72a is released from the detent spring 68, and the lever member 60 rotates about the shaft pin 60a.
[0041] As shown in FIG. 7(b), when the outdoor handle 34 rotates to the 45-degree state, the slide piece 62 slides and displaces to the central position of the X-direction width of the base member 58. The pins 66a and 66b are at the central portions of the vertical guide long holes 621d and 622d. The horizontal guide pin 74 is at the central portion of the horizontal guide long hole 62e.
[0042] As shown in Fig. 7(c), when the outdoor handle 34 rotates to a state of 90 degrees, the slide piece 62 is displaced by sliding to the position most biased toward the X1 side within the X-direction width of the base member 58, and further displacement is restricted. The pins 66a and 66b are at the X2-side ends of the vertical guide long holes 621d and 622d. The horizontal guide pin 74 is at the outdoor-side end of the horizontal guide long hole 62e.
[0043] In the operations of Figs. 7(a) to 7(c), the slide piece 62 is displaced in the X direction by the horizontal guide pin 74 pressing against the side wall of the horizontal guide long hole 62e. That is, the X-direction position of the slide piece 62 is defined by the horizontal guide pin 74. Also, the expected-direction position of the slide piece 62 is maintained by the pins 66a and 66b relatively displacing within the vertical guide long holes 621d and 622d. That is, the shaft pin 66a has the action as a rotation axis and the guide action in the X direction.
[0044] Since the lever member 60 rotates about the shaft pin 66a, the slide piece 62 that is in sliding contact with the inner surface of the rotation center plate 70 receives a counterclockwise rotational force but is guided in contact with the two pins 66a and 66b that are displaced in the X direction and the expected direction, so the posture is properly maintained. Fig. 7.
[0045] Also, as shown in Fig. 7(a), when the outdoor handle 34 rotates from the position along the X1 direction to point toward the outdoor side as shown in Fig. 7(c), the slide piece 62 slides toward the X1 direction.
[0046] When the slide piece 62 is displaced in the X1 direction, the linkage bar 42 (see FIGS. 2 and 3) is pushed out in the X1 direction by the bar driving piece 62b via the pin 42b. Therefore, the lock of the shoji 14 by the locking device 36 is released and it can be opened and closed. Further, when the slide piece 62 is displaced in the X1 direction, the bracket 78 and the connecting bar 76 are displaced in the X1 direction integrally with the bar driving piece 62b. As a result, the interlocking projection 50a (see FIG. 2) is pushed out in the X1 direction by the operating piece 82. Therefore, the semi-open restriction of the shoji 14 by the fully semi-open device 38 is released and it can be fully opened. In this way, in the fitting 10, the lock release of the shoji 14 and the release of the semi-open restriction can be achieved by only one operation of the outdoor handle 34.
[0047] In the fitting 10, the unlocking device 40 is provided on the vertical stile 20, and a mechanism for converting the operating direction between the unlocking device 40, the locking device 36, and the fully semi-open device 38 becomes unnecessary. Further, the movement of the outdoor handle 34 branches from the bar driving piece 62b and is transmitted to the directly connected connecting bar 76 and the linkage bar 42 that is pressed only on one side via the pin 42b. Therefore, it is not necessary to provide a switching fitting separately. In this way, the fitting 10 has a reduced number of parts and a simple mechanism is realized.
[0048] In the above embodiment, the unlocking device 40, the main parts of the locking device 36 and the fully semi-open device 38 are provided on the vertical stile 20, and the lock receiving portion 46 and the fully semi-open device receiving portion 56 are provided on the vertical frame 30. However, the components of the vertical stile 20 and the components of the vertical frame 30 may be arranged in reverse. Regarding the unlocking device 40, the mounting target profile may be the vertical frame 30.
[0049] The present invention is not limited to the above-described embodiments, and it goes without saying that it can be freely changed without departing from the gist of the present invention.
[0050] The fitting according to the present invention is a fitting provided with a shoji that can be opened and closed on the inner peripheral side of a frame body, and includes a locking device that locks the shoji in a closed state with respect to the frame body, a full / half opening device that restricts the possible opening degree of the shoji to a half-open state, and a lock release device that releases the locked state of the shoji by the locking device from the outdoor side. The lock release device includes a base member provided with a vertical stile of the shoji or a vertical frame of the frame body as a mounting target member, an outdoor handle that rotates with respect to the base member and is provided so as to be rotatable from the outdoor side, a slide piece that is driven by the rotation operation of the outdoor handle and slides in the longitudinal direction of the mounting target member, a first bar provided along the longitudinal direction for switching between locking and unlocking of the shoji by the locking device, and a second bar provided along the longitudinal direction for switching the possible opening degree of the shoji by the full / half opening device between a half-open state and a fully open state. The slide piece presses and displaces the first bar by the sliding operation to release the lock by the locking device, and the second bar is fixed to the slide piece and slides together with the slide piece to release the restriction of the half-open state by the full / half opening device and enable full opening.
[0051] In such a fitting, the lock release device is provided on the vertical stile or the vertical frame, and a mechanism for converting the operating direction between the lock release device, the locking device, and the full / half opening device becomes unnecessary. Therefore, both the locking device and the full / half opening device can be operated with a simple structure by a single operation of the outdoor handle.
[0052] An outer peripheral side protruding piece protruding to the outer peripheral side is formed on the outdoor side finding surface of the mounting target member, the outdoor handle extends along the prospective direction and the longitudinal direction from the rotation center plate, the rotation center plate slides with respect to the inner surface of a flat plate along the prospective direction and the longitudinal direction in the base member, and the flat plate may be arranged at a position shifted to the outer peripheral side by a column portion with respect to the mounting target member so that the outdoor handle does not interfere with the outer peripheral side protruding piece. Thereby, it becomes unnecessary to notch the outer peripheral side protruding piece in accordance with the operating range of the outdoor handle.
