The case mounting holes 38b are formed in a pair of left and right case mounting pieces 383 projecting from the lower end of the front cover 38 toward the outdoor side.

  Such a front cover 38 is attached to the surface of the indoor-side finding surface of the door toe 23 with a front screw 46 or the like with a pair of left and right rod-shaped members 384 interposed therebetween. More specifically, a rectangular opening (not shown) (hereinafter also referred to as a door toe opening) is formed on the indoor side of the door toe 23, and the front cover 38 includes a handle opening 381 and a door opening 381. The button opening 382 is attached to the indoor-side finding surface in a state where it faces the door-to-door opening. At this time, the case attachment piece 383 passes through the door toe opening and enters the door toe 23. Note that reference numeral 385 in the figure denotes a screw cover for hiding the front screw 46.

  With respect to such a front cover 38, the case 31 in which the handle 32, the catch 33, the button 34, the pusher 35, and the arm 37 are accommodated from the inside of the door rod 23, the case mounting hole 31a is the case mounting hole. 38a and the case mounting hole 31b overlaps the case mounting hole 38b, the case mounting screw 47 penetrating the case mounting hole 31a is screwed into the case mounting hole 38a, and the case mounting hole 38b is The case 31 is disposed inside the door rod 23 by the case mounting screw 48 penetrating through the case mounting hole 31b. In this case, the handle 32 is exposed to the indoor side through the handle opening 381, and the pressing portion 34 a of the button 34 is exposed to the indoor side through the button opening 382.

  Then, the locking device 30 is configured by connecting a linkage bar 50 as shown in FIG. 2 to the connection base 401 of the connection piece 40 fitted to the operation piece 36 slidably contacting the case 31.

  Here, the linkage bar 50 is a long member whose vertical direction is the longitudinal direction, and is disposed in a state of being exposed from the prospective surface of the door-end rod 23. In this linkage bar 50, two engaging pins 51 are formed so as to protrude upward and downward. These engagement pins 51 can be engaged with the lock receiving portion 60 disposed on the prospective surface of the vertical frame 14 (13).

  The lock receiving portion 60 is formed by bending a plate-like member made of a metallic material such as aluminum, for example, and has a flat plate-like lock receiving base portion 61 extending in the vertical direction, and the lock receiving base portion. A lock receiving upper portion 62 that extends toward the right side from the upper end portion of 61 and then bends upward, and a lock receiving portion that extends toward the right side from the lower end portion of this lock receiving base portion 61 and then bends downward. A lower part 63 is provided.

  The lock receiving portion 60 has a lock receiving screw (not shown) penetrating through lock receiving holes 62a and 63a formed in the upper end portion of the lock receiving upper portion 62 and the lower end portion of the lock receiving lower portion 63. It is attached to the prospective surface of the vertical frame 14 (13) by being screwed to the prospective surface of 13). In these lock receiving portions 60, a lock receiving opening 60 a is formed in the lock receiving base portion 61 and the lock receiving lower portion 63, and the opening width of the lock receiving lower portion 63 is large enough to allow passage of the tip end portion of the engagement pin 51. And the opening width of the lock receiving base portion 61 is smaller than the tip end portion of the engagement pin 51. These lock receiving portions 60 allow the engagement pin 51 to relatively enter the lock receiving opening 60a from below, and enter the engagement state with the engagement pin 51 when the engagement pin 51 enters.

  Accordingly, the operating piece 36 constituting the locking device 30 is connected to the linkage bar 50 having the engaging pin 51 that can be engaged with the lock receiving portion 60 via the connecting piece 40 and also connected to the arm 37, and the movement of the arm 37. Accordingly, the linkage bar 50 is moved along the longitudinal direction of the door toe 23 on the prospective surface of the door toe 23.

As the arm 37 moves upward, the pusher 35 whose lower surface is in contact with the upper end of the arm 37 moves upward against the urging force of the compression coil spring 351.

  Then, as shown in FIGS. 3, 5, and 6, the handle 32 is locked to the catch 33 by the locking protrusion 33 b of the catch 33 entering the locking recess 32 b of the handle 32. As a result, the advancing movement of the handle 32 toward the indoor side is prevented, and the pusher 35 is held in a state of moving upward.

  Thus, when the handle 32 is engaged with the catch 33, the handle gripping portion 322 of the handle 32 slightly protrudes indoors from the front cover 38, and most of the handle 32 is concealed.

  Further, as a result of the upward movement of the arm 37, the linkage bar 50 also moves upward on the prospective surface of the door rod 23 via the operating piece 36 and the connecting piece 40, so that the meshing pin 51 of the lock receiving portion 60 is moved. The lock device 30 engages with the lock receiving portion 60 by entering the lock receiving opening 60 a from below and engaging with the lock receiving portion 60. In this way, the locking device 30 is engaged with the lock receiving portion 60 to prevent the opening of the shoji 20 from the opening frame 10.

  When the pressing portion 34a of the button 34 is pressed as shown in FIG. 7 in the state where the opening of the shoji 20 is prevented in this way, the button 34 moves toward the outdoor side. When the button 34 moves toward the outdoor side, the action piece 34 b of the button 34 comes into contact with the catch contact piece 333, so that the catch 33 rotates upward against the urging force of the catch spring 334. When the catch 33 rotates upward, the locking projection 33b is released from the locking recess 32b, and the locking state between the catch 33 and the handle 32 is released. The handle 32 released from the locked state with the catch 33 becomes free. Further, when the catch 33 and the handle 32 are released from the locked state, the pusher 35 is urged by the compression coil spring 351 and starts moving downward, whereby the arm 37 is pressed and the handle 32 is pressed. Starts moving into the room.

  When the pressing operation on the button 34 is released, the catch 33 is rotated downward by the catch spring 334, whereby the action piece 34b is pressed by the catch contact piece 333, and the button 34 moves to the indoor side. To return to the original state.

  When the pusher 35 moves downward, the arm 37 is pressed by the pusher 35 and moves downward. The operating piece 36 connected to the arm 37 also moves downward while sliding on the outer surface of the case 31. To do. As described above, a high-viscosity lubricant called damping grease is applied to the slidable contact area on the outer surface of the case 31 with the working piece 36, so that the working piece 36 and this are connected thereto. The arm 37 slowly moves downward, whereby the handle 32 also slowly moves forward toward the indoor side.

  As shown in FIGS. 8 to 10, the arm connection pin 45 a comes into contact with the lower end edge of the case connection hole 31 c, so that the downward movement of the arm 37 is stopped. In addition, the advance movement of the handle 32 toward the indoor side is also stopped.

  In this way, the operating piece 36 and the connecting piece 40 are moved downward by the downward movement of the arm 37, so that the linkage bar 50 is also moved downward. Accordingly, as shown in FIG. 11, the engagement pin 51 provided on the linkage bar 50 is released from the lock receiving portion 60 to release the engagement state with the lock receiving portion 60, and the lock device 30 is released from the lock receiving portion 60. And a disengaged state. In this way, the lock device 30 is disengaged from the lock receiving portion 60, thereby allowing the opening of the shoji 20 to the opening frame 10. Therefore, as shown in FIG. 12, the shoji 20 can be moved open toward the left side.

  According to the lock device 30 according to the embodiment of the present invention as described above, the case 31 is provided on the case 31 provided inside the door toe wall 23 in a state of being exposed from the indoor side finding surface of the door toe wall 23. A catch 33 that is pivotable along the prospective direction of the door toe 23 so that the supported handle 32 moves forward and backward with respect to the indoor side and that is pivotably disposed on the case 31 is retracted from the indoor side. In the case of locking with the moved handle 32, the handle 32 is prevented from moving forward toward the indoor side, and the button 34 is rotated by being pressed, and the locked state with the handle 32 is released. In this case, since the handle 32 is set in a free state, the handle 32 can be concealed when the handle 32 and the catch 33 are locked.

  Moreover, since the handle base 321 is pivotally supported by the case 31 and the handle base 321 and the handle gripping part 322 are connected to the arm 37, the pusher 35 is biased by the compression coil spring 351. By moving, the case 31 and the arm 37 can move to the indoor side of the door toe 23 in a state where the two points are supported, thereby stabilizing the state in which the handle 32 has advanced and moved to the indoor side. be able to. Therefore, the handle 32 can be concealed, and the state where the handle 32 has advanced to the indoor side (outside) of the handle 32 can be stabilized.

  According to the lock device 30 described above, when the handle 32 that moves backward with the shoji 20 closed with respect to the opening frame 10 and the catch 33 are locked, the arm 37 moves in conjunction with the backward movement of the handle 32. As the linkage bar 50 moves, the engagement pin 51 engages with the lock receiving portion 60 and engages with the lock receiving portion 60, and the button 34 is pressed with the shoji 20 closed against the opening frame 10. When the locked state between the catch 33 and the handle 32 is released by the movement, the arm 37 pressed by the pusher 35 moves to move the handle 32 into the indoor side, and the linkage bar 50 moves to move the engagement pin. 51 is detached from the lock receiving portion 60 and is in a non-engagement state with the lock receiving portion 60, so that the door 51 can be well disposed on the indoor-side finding surface, and as a result, the lock can be apparatus It does not need to be excessively large prospective dimension of door leading end stile 23 for installation. Accordingly, the design property can be improved.

  According to the locking device 30, the arm 37 has a curved shape so as to protrude toward the outdoor side, so that it rotates about the central axis of the arm connecting pin 45 a along the vertical direction with respect to the case 31. Therefore, it is possible to reduce the size of the space that allows the movement of the arm 37 in the expected direction. Therefore, the size of the locking device 30 in the expected direction can be reduced.

  Further, since the arm 37 has a curved shape, the minimum width between the front cover 38 and the handle 32 can be sufficiently secured when the handle 32 is moved forward to the indoor side, and fingers can be pinched. Can be suppressed.

  According to the lock device 30, since the high-viscosity lubricant is applied to the sliding contact area of the case 31 with the operating piece 36, the handle 32 can be slowly moved into the indoor side, and the user can There is no risk of injury and an easy-to-handle impression can be given to the user.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the above-described embodiment, the shoji 20 is movable along the left-right direction with respect to the opening frame 10. However, in the present invention, the shoji is a so-called outside that rotates along the prospective direction of the opening frame. An opening type or an inner opening type may be used. In the present invention, the present invention can be applied not only to the two sliding door sliding windows as in the embodiment described above, but also to the three sliding door sliding windows and the four sliding door sliding windows. The present invention can also be applied to a single sliding window that opens and closes a single shoji.

  In the above-described embodiment, the lock device 30 is provided on the door rod 23 and the lock receiving portion 60 is provided on the vertical frames 13 and 14, but in the present invention, when the shoji is closed with respect to the opening frame. The lock receiving part may be provided on the bag and the lock device may be provided on the frame.

  In the embodiment described above, the arm 37 has a curved shape so as to protrude toward the outdoor side. However, in the present invention, the arm (arm 37) protrudes toward the outdoor side as a whole. It is preferable that the bent shape is formed so that, for example, a bent shape or a bent shape may be formed.

  In the above-described embodiment, the damping means for damping the rotation of the handle 32 by slowly applying the high-viscosity lubricant to the sliding contact area of the case 31 with the operating piece 36 and slowly moving the handle 32 to the indoor side. However, in the present invention, it is sufficient that the high-viscosity lubricant is applied between the members that are in sliding contact with each other by the rotation of the handle, and the application location of the high-viscosity lubricant is not limited. In the present invention, the lubricant is not limited to a high-viscosity lubricant called a damping grease, and a gel-like lubricant may be applied, or between the members in the sliding contact portion by frictional force using various brakes. The relative speed may be reduced.

  For example, as shown in FIGS. 13 (A) and 13 (B), a damper is provided between members that move relative to each other by the rotation of the handle 32, here between the operating piece 36 (arm connecting pin 45 a) and the case 31. By interposing the mechanism 70, attenuation means for attenuating the rotation of the handle 32 and slowly moving the handle 32 to the indoor side may be configured. The damper mechanism 70 is a rack-and-pinion mechanism including a pinion gear 72 fixed to a plate 71 attached to the operating side portion 362 of the operating piece 36, and a rack gear 73 fixed to the case 31 and meshing with the pinion gear 72. . The pinion gear 72 is a rotary damper in which high-viscosity oil is filled around its rotation axis, and its rotation is damped. An arm connecting pin 45 a is fastened to the plate 71.

  Therefore, in the damper mechanism 70, when the operating piece 36 moves in conjunction with the rotation of the handle 32 in the indoor advancement direction, the pinion gear 72 rotates in mesh with the rack gear 32 to generate a damping force. This damping force is transmitted to the arm connecting pin 45a via the plate 71, and the movement of the arm connecting pin 45a and the operating piece 36 is made slow, and thereby the turning of the handle 32 is also made slow. Further, by using the damper mechanism 70, durability against aging is improved as compared with the high viscosity lubricant, and maintenance is almost unnecessary. The damper mechanism 70 may be used together with the high viscosity lubricant, and the same applies to a damper mechanism 75 and a rotary damper 78 described later.

  Further, for example, as shown in FIG. 14, a damper mechanism 75 is interposed between members that move relative to each other by the rotation of the handle 32, here, between the operating piece 36 (arm connection pin 45 a) and the case 31. Further, attenuation means for attenuating the rotation of the handle 32 and slowly moving the handle 32 to the indoor side may be configured. The damper mechanism 75 includes a rod 76 whose tip is connected to the arm connecting pin 45a on the operating side portion 362 side of the operating piece 36, and a cylinder 77 that is fixed to the case 31 and inserted so that the rod 76 can be moved forward and backward. It is a shock absorber mechanism. The cylinder 77 is filled with high-viscosity oil, and a piston (not shown) provided at the base end of the rod 76 receives a damping force, whereby the movement of the rod 76 is damped.

  Therefore, the damper mechanism 75 generates a damping force between the rod 76 and the cylinder 77 when the operating piece 36 moves in conjunction with the rotation of the handle 32 in the indoor advancement direction. This damping force is transmitted from the rod 76 to the arm connecting pin 45a, and the movement of the arm connecting pin 45a and the operating piece 36 is made slow, and thereby the turning of the handle 32 is also made slow. Even when the damper mechanism 75 is used, durability against aging is improved as compared with the high viscosity lubricant, and maintenance is almost unnecessary.

  Furthermore, for example, as shown in FIG. 9, a rotary damper 78 similar to that used for the pinion gear 72 of the damper mechanism 70 may be connected to the handle shaft support pin 41 a that serves as the rotation shaft of the handle 32. This also constitutes a damping means that attenuates the rotation of the handle 32 and slowly moves the handle 32 to the indoor side. Even when this rotary damper 78 is used, durability against aging is improved as compared with the above high-viscosity lubricant, and maintenance is almost unnecessary.
