Summary of the Invention

Problems to be Solved by the Invention

[0004] As a mechanism for unlocking, it is conceivable to rotate the outdoor handle from a position along one of the longitudinal directions so as to point to the outside, slide the predetermined slide piece longitudinally in an interlocking manner, and release the locked state of the locking device via the slide piece. However, it is desirable that the operation of the outdoor handle and the operation of the slide piece are intuitively easy to understand during assembly and maintenance.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide a fitting in which the operation of the mechanism is intuitive and easy to understand.

Means for Solving the Problems

[0006] In order to solve the above-mentioned problems and achieve the object, 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, 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 stile of the shoji or a frame member 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, and 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. By rotating the outdoor handle so that at least the tip thereof faces the outdoor side along one side in the longitudinal direction, the slide piece slides toward the other side in the longitudinal direction to operate the locking device and release the locked state of the shoji.

Advantages of the Invention

[0007] In the fitting according to the present invention, at least the tip of the outdoor handle is displaced toward the other side, and similarly, the slide piece is also displaced toward the other side, so that the operation of the mechanism is intuitive and easy to understand.

Embodiments for Carrying Out the Invention

[0009] 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.

[0010] In the following, for 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 a prospective wall. The search direction is the direction along the up and down perpendicular to the prospective direction in the case of something extending along the horizontal direction such as an upper frame, a lower frame, an upper sash, a lower sash, etc. In the case of something extending along the vertical direction such as a vertical frame, a vertical sash, etc., the horizontal direction along the perpendicular 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 a search wall.

[0011] 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 includes a frame body 12 provided in 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 with respect to the frame body 12 on the outdoor side. In this embodiment, it is assumed that the left side opens and closes based on the hinge on the right side in FIG. 1.

[0012] The shoji 14 is configured by disposing a panel 24 inside a frame 22 formed by surrounding an upper sash 16, a lower sash 18, and left and right vertical sashes 20. The panel 24 is, for example, a glass material. The frame body 12 is configured by surrounding an upper frame 26, a lower frame 28, and left and right vertical frames 30. Each sash member and each frame member are made of a metal such as an aluminum alloy, a resin material, or a composite material thereof, and are each an extruded molding having a substantially uniform cross-sectional shape over the entire length along the longitudinal direction. In the following description, unless otherwise specified, the vertical frame 30 and the vertical sash 20 indicate the left side portions of the pair of left and right sides in FIG. 1.

[0013] Near the left edge of the shoji 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 sash 20, a locking device 36, a full / half opening device 38, and a lock release device 40 are provided.

[0014] Figure 2 is a view showing the vertical frame 30 and the vertical sash 20. The vertical frame 30 shows the inner peripheral side prospective part, and the vertical sash 20 shows the part facing the inner peripheral side prospective part of the vertical frame 30, and they are shown side by side left and right for easy understanding of the correspondence. Note that for the vertical frame 30, the outer peripheral cover is omitted so that the locking device 36, the full / half opening device 38, and the lock release device 40 can be visually recognized. In Figure 2, the linkage bar (first bar) 42 is shown in a dark dotted pattern and the connecting bar (second bar) 76 and its attached parts are shown in a light dotted pattern for easy identification. The longitudinal direction (here, the vertical direction) of the vertical frame 30 and the vertical sash 20 is defined as the X direction, one side (here, the upper side) as the X1 direction, and the other side (here, the lower side) as the X2 direction. The indoor handle 32 is on the X1 side of the full / half opening device 38. The full / half opening device 38 is on the X1 side of the lock release device 40.

[0015] 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 sash 20 and a lock receiving part 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 protrude to the outer peripheral side at a slightly separated position. The pin 42a is on the X1 side of the pin 42b.

[0016] 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 X1 side, and when it is in the open position, it is displaced relatively to the X2 side. The pin 42a is between the full / half opening device 38 and the lock release device 40. When the linkage bar 42 is on the X1 side, it engages with the lock receiving part 46 to lock the shoji 14 in the closed state, and when the linkage bar 42 is on the X2 side, it separates from the lock receiving part 46 to release the lock and make the shoji 14 in an openable / closable state.

[0017] The fully / semi-open device 38 switches the possible opening degree of the shoji 14 between the fully open state and the semi-open state, and is normally regulated to be in the semi-open state. The fully / semi-open device 38 includes a fully / semi-open device base portion 48, a fully / semi-open device slide piece 50, an angle regulating arm 52, a guide member 54, and a fully / semi-open device receiving portion 56. The fully / semi-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 fully / semi-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 fully / semi-open device base portion 48.

[0018] The X1-side end portion of the angle regulating arm 52 is pivotally supported on the fully / semi-open device slide piece 50 by a shaft 52a, and is rotatable toward the indoor side 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 X2-side end portion of the angle regulating arm 52. The fully / semi-open device slide piece 50 is biased toward the X1 side by a spring (not shown). A linkage protrusion 50a that protrudes to the outdoor side is provided on the fully / semi-open device slide piece 50. The linkage protrusion 50a protrudes to the outdoor side more than the fully / semi-open 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 fully / semi-open device receiving portion 56 has a shape that is long in the X direction, and a guide groove 56a that opens downward is formed in the center. In a state where the fully / semi-open device slide piece 50 and the angle regulating arm 52 are displaced toward the X1 side by a spring (the state in Fig. 2), the pin 52b enters the lower end opening portion of the guide groove 56a.

[0019] 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 toward the X1 side with the pin 52b at the lower end guided by the guide groove 56a, and further rotation is restricted by abutting against the X1-side end portion of the guide groove 56a, and the shoji 14 is restricted in the semi-open state. In such a semi-open state, the opening degree of the shoji 14 is, for example, about 10 cm, and ventilation is possible while preventing people from passing through inadvertently.

[0020] Note that pin 42b receives an action from the unlocking device 40. However, when the linkage bar 42 is displaced in the X2 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 projection 50a receives an action from the unlocking device 40 via a connecting bar 76 and an acting piece 82, which will be described later.

[0021] In such a fitting 10, basically, it is not assumed that people pass from the indoor side to the outdoor side. However, an unlocking device 40 is provided so that people can temporarily pass from the outdoor side to the indoor side, and the shoji 14 can be fully opened. "Temporarily" is assumed, for example, during the emergency entry of the fire brigade. However, it does not prevent the use by construction workers, cleaning workers, etc. under the permission of the administrator. Also, although not normally assumed, when it is necessary to fully open the shoji 14 from the indoor side, a dedicated knob may be configured to be detachable from the indoor side with respect to the full-half opening device slide piece 50, and the dedicated knob may be pressed in the X2 direction so that the pin 52b can be detached from the guide groove 56a.

[0022] 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 FIG. 4. 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, it acts on the full-half opening device 38 so that the shoji 14 can be fully opened.

[0023] 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.

[0024] The base member 58 is provided with the vertical frame 20 of the shoji 14 as a mounting object member. Bent-shaped vertical walls 58e are formed on the X1 side and X2 side of the flat plate 58g of the plate-shaped member that is slightly longer in the X direction, and a bent-shaped vertical wall 58f is formed on the indoor side. Further, the ends on the X1 side and X2 side are bent at the tip of the vertical wall 58e to form a crank shape, thereby forming the fixing piece 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 portion of the base member 58 with respect to the vertical frame 20.

[0025] Two long slits 581b and 582b that are elongated in the X direction are formed in the base member 58. One slit 581b is formed near the outdoor side end and closer to the X2 side. The other slit 582b is formed near the indoor side end and closer to the X1 side. That is, the two slits 581b and 582b are in substantially diagonal positions. In this embodiment, the length of the slits 582b and 581b in the X direction is about 1 / 3 of the base member 58.

[0026] Three pin holes 581c, 582c, and 583c are formed in the base member 58. The pin hole 581c is substantially at the center in the expected direction and slightly closer to the X2 side than the center in the X direction. The pin hole 582c is near the indoor side end, at substantially the center in the X direction, and adjacent to the X2 side of the slit 582b. The pin hole 583c is near the X1 side end and adjacent to the outdoor side of the slit 582b. 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. Each pin is fixed 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.

[0027] The vertical wall 58f is lower and inclined compared to the horizontal wall 58e, and a gap 58d is secured where 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.

[0028] The shape of the lever member 60 will be described with reference to 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 substantially semicircular rotation center plate 70, 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 can rotate. A slightly small pin hole 70b is formed in the rotation center plate 70 at a position near the outdoor side of the center hole 70a and on the X1 side. A small horizontal guide pin 74 is fixed to the pin hole 70b in a slightly protruding state.

[0029] 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 slidably contacting 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 handle 34 rotate on a surface along the X direction and the prospective direction. Also, the outdoor handle 34 extends along the prospective direction and the X direction from the rotation center plate 70.

[0030] The connecting plate 72 is a substantially parallelogram, and its outdoor side edge forms a part of the outdoor handle 34. The lever member 60 is rotationally 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, a part of the detent spring 68 elastically engages with a small recess 72a near the corner of the connecting plate 72, thereby positioning the lever member 60 so that it does not move inadvertently.

[0031] 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 spaced apart to the extent that it can be gripped by hand and has a length sufficient for manual gripping.

[0032] 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, a bar drive piece 62b, and two guide bending portions (plate-like guide portions) 621c, 622c. The guide bending portions 621c, 622c are formed by bending a portion protruding from the slide sliding portion 62a at 90 degrees in the material plate and are in a plate shape along the X direction. The bar drive piece 62b is bent in two steps from the indoor side and near the X1 end of the slide sliding portion 62a and protrudes indoors. A pin 42b is adjacent to the X2 side of the bar drive piece 62b (see FIGS. 2 and 3).

[0033] One guide bending portion 621c is formed near the outdoor side end and on the X2 side and fits into the slit 581b. The other guide bending portion 622c is formed at the indoor side end and on the X1 side and fits into the slit 582b. That is, the two guide bending portions 621c, 622c are in substantially diagonal positions. The guide bending portion 621c is on the outdoor side of the pin 66a, and the guide bending portion 622c is on the indoor side of the pin 66b. In this embodiment, the X-direction length of the guide bending portions 621c, 622c is about 1 / 3 of the slits 581b, 582b. The guide bending portions 621c, 622c have almost no clearance in the expected direction with respect to the slits 581b, 582b and contact the inner surfaces of the slits 581b, 582b over substantially the entire X-direction length. That is, the guide bending portions 621c, 622c and the slits 581b, 582b are in line contact rather than point contact.

[0034] The slide sliding part 62a is formed with two longitudinal guide slots 621d and 622d that are long in the X direction, and a transverse guide slot 62e that is long in the prospective direction. The longitudinal guide slot 621d is on the X2 side and outside the room relative to the longitudinal guide slot 622d. The transverse guide slot 62e is outside the room compared to the longitudinal guide slot 621d. The prospective width of the transverse guide slot 62e is smaller than the X-direction width of the longitudinal guide slot 621d. A shaft pin 66a is inserted through the longitudinal guide slot 621d. A longitudinal guide pin 66b is inserted through the longitudinal guide slot 622d. A transverse guide pin 74 is inserted through the transverse guide slot 62e.

[0035] Returning to FIG. 2, the vertical frame 20 is provided with a connecting bar 76 extending from the vicinity of the X1 side of the unlocking device 40 toward the X1 side. The X2-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 X1-side end of the connecting bar 76 extends through the outside of the room of the fully and half-opening device 38 and further to the X1 side and is held by a holding member 80 so as to be movable up and down. An acting piece 82 protruding toward the inside of the room is provided at a portion slightly on the X2 side of the connecting bar 76 from the holding member 80. The acting piece 82 is near the X1 side of the interlocking protrusion 50a, and when the connecting bar 76 is displaced to the X2 side, it presses and displaces the interlocking protrusion 50a.

[0036] FIG. 6 is a diagram showing the state of operation 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. 6 shows the unlocking device 40 as viewed from the inner peripheral side.

[0037] As shown in FIG. 6(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 X1 side within the X-direction width range of the base member 58. The pins 66a and 66b are at the X2-side ends of the vertical guide long holes 621d and 622d. The guide bending portions 621c and 622c are at the X1-side ends of the slits 581b and 582b. 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 counterclockwise direction in FIG. 6 from this state, the recess 72a is released from the detent spring 68, and the lever member 60 rotates about the shaft pin 60a.

[0038] As shown in FIG. 6(b), when the outdoor handle 34 rotates to the state of 45 degrees, the slide piece 62 slides and displaces to the central position within 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 guide bending portions 621c and 622c are at the central portions of the slits 581b and 582b. The horizontal guide pin 74 is at the central portion of the horizontal guide long hole 62e.

[0039] As shown in FIG. 6(c), when the outdoor handle 34 rotates to the state of 90 degrees, the slide piece 62 slides and displaces to the position most biased toward the X2 side within the X-direction width range of the base member 58, and further displacement is restricted. The pins 66a and 66b are at the X1-side ends of the vertical guide long holes 621d and 622d. The guide bending portions 621c and 622c are at the X2-side ends of the slits 581b and 582b. The horizontal guide pin 74 is at the outdoor-side end of the horizontal guide long hole 62e.

[0040] In the operations of FIGS. 6(a) to 6(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 relative displacement of the pins 66a and 66b 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.

[0041] Since the lever member 60 rotates about the shaft pin 66a, the slide piece 62 that slidably contacts the rotation center plate 70 receives a counterclockwise rotational force and is guided in contact with two pins 66a and 66b that are displaced in the X direction and the prospective direction, so that its posture is properly maintained.

[0042] During a series of operations, the posture of the slide piece 62 is more reliably maintained by the guide bent portions 621c and 622c. The pins 66a and 66b guide the slide piece 62 only at the same position as or on the indoor side of the shaft pin 66a, which is the rotation center of the lever member 60, while the guide bent portions 621c and 622c guide it on both the outdoor side and the indoor side of the shaft pin 66a. Since the guide bent portion 621c guides on the outdoor side of the pin 66a and the guide bent portion 622c guides on the outdoor side of the pin 66b, the slide piece 62 can be stably guided at a position separated in the prospective direction. The X-direction position of the guide bent portion 621c is the same as or on the X2 side of the pin 66a, and the X-direction position of the guide bent portion 622c is on the X1 side of the pin 66b, and the slide piece 62 can be stably guided at a position separated in the X direction.

[0043] In other words, at any point during the rotation operation of at least the outdoor handle 34, or at an intermediate point during the rotation operation of the outdoor handle 34 (see Fig. 6(b)), if one guide bent portion 621c is provided in the X2 direction and on the outdoor side with reference to the shaft pin 66a, which is the rotation center, and the other guide bent portion 622c is provided in the X1 direction and on the indoor side, the two can guide the slide piece 62 in a well-balanced manner at a position moderately separated from the shaft pin 66a in the X direction and the prospective direction.

[0044] The pins 66a and 66b are cylindrical and have sufficient strength. They slide in contact with the vertical guide long holes 621d and 622d somewhat smoothly, but since they are in point contact, there is a concern that if used repeatedly, gnawing between the metals may occur and the operating force may become heavy. In contrast, since the guide bent portions 621c and 622c are in linear contact with the slits 581b and 582b, the load is dispersed, preventing gnawing of the slits 581b and 582b and the pins 66a and 66b, and maintaining a light operating force.

[0045] Also, as shown in FIG. 6(a), when the outdoor handle 34 rotates from the position along the X1 direction to point toward the outdoor side as shown in FIG. 6(c), the slide piece 62 slides in the X2 direction. The lever member 60 and the outdoor handle 34 perform a rotating operation, but at least the tip portion of the outdoor handle 34 with the largest displacement amount is displaced in the X2 direction. In contrast, since the slide piece 62 is also displaced in the X2 direction, the operation of the mechanism is intuitive and easy to understand, making assembly, maintenance, etc. easier.

[0046] When the slide piece 62 is displaced in the X2 direction, the linkage bar 42 (see FIGS. 2 and 3) is pushed out in the X2 direction by the bar driving piece 62b via the pin 42b, so that the lock of the shoji 14 by the locking device 36 is released and it can be opened and closed. Also, when the slide piece 62 is displaced in the X2 direction, the bracket 78 and the connecting bar 76 are displaced in the X2 direction integrally with the bar driving piece 62b. As a result, the interlocking projection 50a (see FIG. 2) is pushed out in the X2 direction by the acting piece 82, so that the semi-open restriction of the shoji 14 by the full semi-open device 38 is released and it can be fully opened. In this way, in the fitting 10, it is possible to release the lock of the shoji 14 and the semi-open restriction release with only one operation of the outdoor handle 34.

[0047] In the above-described embodiment, the slits 581b and 582b are provided in the base member 58, and the guide bending portions 621c and 622c are provided in the slide pieces 62, but the reverse may also be possible. In the reverse case, the relative positions of the guide bending portions 621c and 622c with respect to the shaft pin 66a are fixed. Also in this case, if the guide bending portion 621c is provided in the X2 direction and the outdoor side with the shaft pin 66a as a reference, and the guide bending portion 622c is provided in the X1 direction and the indoor side, the two can guide the slide piece 62 in a well-balanced manner at positions moderately separated from the shaft pin 66a in the X direction and the prospective direction.

[0048] The slits 581b and 582b are not limited to the through shape formed in the slide sliding portion 62a in a broad sense, and may have a bottomed shape as long as the guide bending portions 621c and 622c can be fitted and guided therein.

[0049] In the above-described embodiment, the unlocking device 40, the main parts of the locking device 36 and the full / half opening device 38 are provided in the vertical frame 20, and the lock receiving portion 46 and the full / half opening device receiving portion 56 are provided in the vertical frame 30. However, the components of the vertical frame 20 and the components of the vertical frame 30 may be arranged in reverse. Regarding the unlocking device 40, the attachment target profile may be the vertical frame 30.

[0050] 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.

[0051] 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, and includes a locking device that locks the shoji door in a closed state with respect to the frame body, and a unlocking device that unlocks the locked state of the shoji door by the locking device from the outdoor side. The unlocking device includes a base member provided with a frame member of the shoji door or a frame member 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, and 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. When the outdoor handle rotates so as to direct the outdoor side from a position along one side of the longitudinal direction, the slide piece slides toward the other side of the longitudinal direction, and the locking device is operated to release the locked state of the shoji door.

[0052] In such a fitting, at least the tip of the outdoor handle is displaced toward the other side, and similarly, the slide piece is also displaced toward the other side, so that the operation of the mechanism is intuitive and easy to understand.

[0053] A slit may be formed along the longitudinal direction in one of the base member or the slide piece, and a plate-shaped guide portion inserted into the slit may be provided on the other. Since the plate-shaped guide portion is in linear contact with the slit, the load is dispersed, wear can be prevented, and a light operating force can be maintained.

[0054] Two plate-shaped guide portions are provided. At least in an intermediate state of the rotation operation of the outdoor handle, one of the plate-shaped guide portions is provided on one side of the longitudinal direction and in one of the prospective directions with reference to the rotation center of the outdoor handle, and the other plate-shaped guide portion is provided on the other side of the longitudinal direction and in the other of the prospective directions with reference to the rotation center of the outdoor handle. Thereby, the two plate-shaped guide portions can guide the slide piece in a well-balanced manner at positions appropriately separated from the rotation center in the longitudinal direction and the prospective direction.

[0055] A fully half-open device that restricts the possible opening degree of the shoji to a half-open state, a first bar provided along the longitudinal direction and switching between locking and unlocking of the shoji by the locking device, and a second bar provided along the longitudinal direction and switching the possible opening degree of the shoji by the fully half-open 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 fully half-open device and enable full opening. Thereby, both the locking device and the fully half-open device can be actuated by one operation of the outdoor handle.
