A kick spring 524 is arranged on the outdoor side of the rack 52. The kick spring 524 is hooked onto a pin 513 that projects inside the case 51. One end 524a of the kick spring 524 is latched to a locking pin 514 provided inside the case 51. The other end 524b of the kick spring 524 is bent into an arc shape and elastically abuts against the stepped portion 523 of the rack 52.

Engagement recesses 523a and 523b provided in the step portion 523 define the upper end position and lower end position of the movement stroke of the rack 52. At the upper end position of the movement stroke of the rack 52, as shown in FIG. 5, the other arcuate end 524b of the kick spring 524 engages with the lower engagement recess 523b. At the lower end position of the movement stroke of the rack 52, the lower end of the rack 52 protrudes downward from the bottom plate 512 of the case 51, as shown in FIG. The other arcuate end 524b of the kick spring 524 engages with the upper engagement recess 523a. When the rack 52 moves up and down, a click feeling is obtained at the upper and lower end positions of the movement stroke, and the rack 52 is held at each position, improving operability.

The guide spur gear 53 is disposed at the lower part of the case 51 and is rotatably supported by a support shaft J1 provided in the case 51. The guide spur gear 53 meshes with the rack teeth 521. As shown in FIG. 6, the guide spur gear 53 has a boss portion 531 that protrudes along the support shaft J1. The outer circumference of the boss portion 531 is provided with an arc-shaped outer circumferential surface 531a and a locked surface 531b having a shape in which a portion of the outer circumferential surface is cut flat. As a result, the cross section of the boss portion 531 perpendicular to the support shaft J1 has a substantially D-shaped outer shape. The guide spur gear 53 is rotatable about the support shaft J1 in conjunction with the vertical movement of the rack 52.

The large-diameter spur gear 54 and the small-diameter spur gear 55 are arranged in the upper part of the case 51 and are rotatably supported by a support shaft J2 provided in the case 51. The large diameter spur gear 54 meshes with the rack teeth 521. As shown in FIG. 7, the large diameter spur gear 54 and the small diameter spur gear 55 are coaxially provided. The large-diameter spur gear 54 has an engagement convex shaft 541 that protrudes along the support shaft J2. The small diameter spur gear 55 has an engagement hole 551 that engages with the engagement convex shaft 541. The large-diameter spur gear 54 and the small-diameter spur gear 55 are integrated around the support shaft J2 in conjunction with the vertical movement of the rack 52 by engaging the engagement convex shaft 541 and the engagement hole 551 with each other. Rotate.

The trigger 56 is arranged inside the case 51 above the guiding spur gear 53 and below the large-diameter spur gear 54 along the indoor-outdoor direction. The trigger 56 has a guide hole 561 that is long in the indoor and outdoor directions. A guide protrusion 515 provided on the case 51 is engaged in the guide hole 561 . The trigger 56 is supported so as to be movable in the indoor and outdoor directions within a range in which the guide protrusion 515 is movable relative to the guide hole 561. As shown in FIG. 5, when the trigger 56 is moved most toward the outdoor side, the end of the trigger 56 on the outdoor side protrudes from the case 51 toward the outdoor side. At this time, the trigger 56 protrudes toward the outdoor side from the outdoor side finding surface 34b of the joining stile 34 to such an extent that it comes into contact with the joining stile 44 of the outer shoji 4.

A spring receiving portion 562 that projects downward is integrally provided on the lower surface of the trigger 56. One end of a compression spring 565 is in contact with the spring receiving portion 562 . The other end of the compression spring 565 is fixed to a spring fixing piece 516 provided on the case 51. The compression spring 565 protrudes toward the outdoor side from the spring fixing piece 516, and is in contact with the spring receiving portion 562 at its protruding end. When compressed, the compression spring 565 exerts a biasing force toward the outdoor side on the trigger 56 via the spring receiving portion 562.

An arcuate recess 563 is provided on the lower surface of the indoor end of the trigger 56 . A flat locking surface 564 is provided on the lower surface of the arcuate recess 563 on the further indoor side along the indoor/outdoor direction. The guide spur gear 53 is supported by the support shaft J1 by fitting the boss portion 531 inside the arcuate recess 563 of the trigger 56. The arcuate outer peripheral surface 531a of the boss portion 531 is along the arcuate surface of the arcuate recess 563.

The right side of the end of the trigger 56 on the outdoor side is tapered toward the outdoor side. As a result, an inclined surface 566 is formed on the tip surface of the trigger 56 on the outdoor side. When the inclined surface 566 comes into contact with the connecting frame 44 of the outer shoji 4, it slides against the connecting frame 44, thereby causing the trigger 56 to move toward the indoor side while compressing the compression spring 565. gradually retreat.

The hanger 57 is arranged between the large-diameter spur gear 54 and the trigger 56 in the case 51, and is rotatably supported by a support shaft J3 provided in the case 51. On the outer periphery of the hanger 57, an arc-shaped engagement plate 571 and a gear portion 572 are provided, which are arranged with the support shaft J3 in between. The gear portion 572 meshes with the small diameter spur gear 55. Therefore, when the large diameter spur gear 54 rotates in conjunction with the vertical movement of the rack 52, the hanger 57 rotates via the small diameter spur gear 55. The arcuate engagement plate 571 is placed in a locked position and an unlocked position by rotation of the hanger 57, respectively.

A spring locking convex portion 573 is provided on the side surface of the hanger 57 . One end of a tension spring 574 is locked to the spring locking convex portion 573 . The other end of the tension spring 574 is locked to a spring locking piece 517 provided on the case 51. The biasing force of the tension spring 574 acts in the locking direction from the middle of the locking process when the hanger 57 is engaged with the receiver 50B, and acts in the unlocking direction from the middle of the unlocking process when the hook 57 is disengaged from the receiver 50B. It acts on Therefore, the locking/unlocking operation can be easily performed.

The receiver 50B has an engagement piece 58. The engagement piece 58 is disposed on the indoor side finding surface 44a of the joining stile 44 of the outer shoji 4 so as to be able to engage with the arcuate engagement plate 571 of the hanger 57.

1 and 4 show the locked state of the locking device 5. In this state, the inner shoji 3 and the outer shoji 4 are closed, and the joining frames 34 and 44 are overlapped. The rack 52 is located at the upper end of the travel stroke. The trigger 56 is most retracted toward the indoor side by contacting the joining stile 44 of the outer shoji 4, thereby compressing the compression spring 565. This state is the triggered state. The arcuate engagement plate 571 of the hanger 57 protrudes from the outdoor side finding surface 34b of the matching stile 34 of the inner shoji 3 and engages with the engagement piece 58 of the receiver 50B. At this time, since the guiding spur gear 53 is rotatable inside the arc-shaped recess 563 of the trigger 56, the rack 52 can be moved downward for unlocking.

FIG. 5 shows the lock device 5 in an unlocked state. In this state, at least one of the inner shoji 3 and the outer shoji 4 is open, and the joining frames 34 and 44 do not overlap. The rack 52 is located at the lower end position of the travel stroke. This state is a trigger release state. The hanger 57 rotates in conjunction with the downward movement of the rack 52, disposes the arc-shaped engagement plate 571 inside the case 51, and releases the engagement with the engagement piece 58 of the receiver 50B. . At this time, since the locked surface 531b of the boss portion 531 of the guide spur gear 53 faces the trigger 56 side, the trigger 56 moves forward toward the outdoor side by the urging force of the compression spring 565. Since the locking surface 564 of the advanced trigger 56 is disposed facing the locked surface 531b, the guide spur gear 53 cannot rotate. Therefore, the rack 52 cannot be moved upward unless the trigger 56 is retreated toward the indoor side due to the overlapping of the connecting frames 34 and 44, and the unlocked state is maintained.

The operating portion 6 of the locking device 5 is connected to a connecting plate 522 protruding from the cutout portion 34c on the indoor side finding surface 34a of the matching stile 34 of the inner shoji 3. As shown in FIG. 10, the operating section 6 includes an operating section main body 61 that extends vertically along the extending direction of the indoor finding surface 34a, and an operating section that further protrudes toward the indoor side from the indoor side surface of the operating section main body 61. It has a protrusion 62.

The operating section main body 61 is formed into a vertically long rectangular shape when viewed from the indoor side. Both upper and lower end portions 611 of the operation section main body 61 have flat surfaces that are substantially parallel to the indoor side finding surface 34a of the joining frame 34. A central portion 612 of the operating portion main body 61 has a shape that gradually swells toward the indoor side from both upper and lower ends 611 toward the center. Therefore, the operating section 6 has a shape that makes it easy to hold the central portion 612 of the operating section main body 61 by hand.

The operating protrusion 62 of this embodiment is arranged on the indoor side surface of the central portion 612 of the operating section main body 61, and protrudes further toward the indoor side. The width of the operation protrusion 62 is approximately equal to the width of the operation section main body 61. The amount of protrusion of the operating protrusion 62 from the operating portion main body 61 is approximately equal to the amount of protrusion of the central portion 612 from the indoor side finding surface 34a of the joining stile 34. The surface 621 of the operation protrusion 62 does not have an acutely projecting corner, and is formed by a convex curved surface that gently continues from the surface of the operation section main body 61.

At least the surface of the operation protrusion 62 of the surfaces of the operation section 6 may be subjected to a non-slip finish. This increases the frictional resistance between the operating protrusion 62 and the elbow EL, specifically clothing or skin, when the operator OP operates the operating protrusion 62 with the elbow EL, as will be explained later. can do. Since the elbow EL is less likely to slip when operating the operating section 6, the operability of the operating section 6 is improved. The anti-slip finishing may be by roughening the surface, or by coating the surface with rubber or resin having a large coefficient of friction. The operating protrusion 62 itself may be made of rubber or resin with a large friction coefficient.

Next, as shown in FIG. 11, a case will be described in which the operator OP, who is holding luggage in both hands, locks and unlocks the sliding window 1 and opens and closes the sliding door 3.

First, when the double-sliding window 1 is fully closed, the operator OP brings one elbow EL into contact with the operation protrusion 62 of the operation part 6 from the indoor side, and in this state, moves the operation protrusion 62 downward. Push down. The operating section 6 moves the rack 52 of the lock device main body 50A downward via the connecting plate 522. As shown in FIG. 5, when the rack 52 is placed at the lower end position of the movement stroke, the rotation of the hook 57 releases the engagement between the arc-shaped engagement plate 571 and the engagement piece 58 of the receiver 50B, and the lock is locked. The device 5 becomes unlocked.

Thereafter, as shown in FIG. 11, the operator OP moves the elbow EL in the opening direction D1 while keeping the elbow EL in contact with the operation protrusion 62, thereby pressing the operation part 6 in the lateral direction. Then, the inner shoji 3 is opened. At this time, as shown in FIG. 5, the trigger 56 advances toward the outdoor side and the locking surface 564 and the locked surface 531b face each other, so that the guide spur gear 53 cannot rotate. After opening the inner shoji 3, even if the operator OP releases the elbow EL from the operation protrusion 62, the unlocked state is maintained.

When closing the inner shoji 3, the operator OP presses the operating part 6 in the lateral direction by moving the elbow EL that is in contact with the operation protrusion 62 in the closing direction D2, and closes the inner shoji 3. Move it closed. When the inner shoji 3 is fully closed, the trigger 56 comes into contact with the joining stile 44 of the outer shoji 4 and retreats most toward the indoor side, as shown in FIG. At this time, the boss portion 531 of the guide spur gear 53 fits into the arcuate recess 563 of the trigger 56, so the guide spur gear 53 is rotatable. Therefore, after the inner shoji 3 is fully closed, when the operator OP pushes the operating protrusion 62 upward on the elbow EL, the rack 52 moves upward and is placed at the upper end position of the movement stroke. As a result, the hook 57 rotates, the arc-shaped engagement plate 571 and the engagement piece 58 of the receiver 50B engage with each other, and the locking device 5 enters the locked state.

At least one of the locking/unlocking operation and the opening/closing operation of the inner shoji 3 may be performed by the operator OP grasping the operating section 6 with his or her hand.

The lock device 5 according to the present embodiment described above has the following effects.

(1) The locking device 5 for fittings of this embodiment is provided in a sliding window 1 which is a fitting that opens and closes an opening by sliding an inner shoji 3 housed in a frame 2 in the horizontal direction. A locking device 5 for fittings that locks and unlocks an internal shoji 3 includes a locking device main body 50A that is provided on the internal shoji 3 and performs a locking/unlocking operation by vertically moving a rack 52 that is a movable member, and an internal shoji 3 an operating section 6 that is provided on the indoor side finding surface 34a and that moves the rack 52 of the locking device main body 50A up and down when operated by the operator OP in the vertical direction; It has an operation protrusion 62 that protrudes toward and can be pressed in the vertical direction by the elbow EL of the operator OP.

According to this, the operator OP can perform the locking/unlocking operation of the locking device 5 for fittings and the opening/closing operation of the interior sash 3 using the elbow EL from the indoor side. Since there is no need to use hands, even the operator OP who is carrying luggage in both hands or the operator who is handicapped can easily perform the locking/unlocking operation and the opening/closing operation of the inner shoji 3. Moreover, since you can lock and unlock the door without using your hands, the risk of getting infected with bacteria or viruses through your hands is also reduced.

(2) In the locking device 5 for fittings described in (1) above, the operating portion 6 is provided so as to be able to open and close the inner sash 3 after being unlocked by being pressed in the lateral direction.

According to this, the operator OP can open and close the inner shoji 3 after unlocking by simply moving the elbow EL, which is brought into contact with the operation part 6, in the lateral direction in a natural manner. It is easy to use because it can perform various operations.

(3) In the locking device 5 for fittings described in (1) or (2) above, the locking device main body 50A moves the rack 52 downward in response to the downward movement of the operating section 6, and performs an unlocking operation. I do.

According to this, the locking device 5 can be unlocked by the natural action of the operator OP simply pushing down the operating protrusion 62 of the operating section 6 with the elbow EL, which is excellent in usability.

Although the above-described fittings are exemplified by the sliding window 1 having two shoji screens, the inner shoji 3 and the outer shoji 4, the fittings of the present disclosure are not limited to this. The fittings of the present disclosure may be provided with three or more shoji, or may be a single-sliding window with only one shoji. The fittings are not limited to windows, but may also be single-sliding doors for entrances that open and close openings by sliding laterally.

The operating protrusion provided on the operating section is not limited to the shape of the operating protrusion 62 shown in this embodiment. The operation protrusion, like the operation protrusion 62A of the operation part 6A shown in FIG. 12, has a vertical width smaller than the vertical width of the operation protrusion 62 shown in FIG. It may be something.

The operating protrusion, like the operating protrusion 62B of the operating part 6B shown in FIG. 13, is formed to have a vertical width larger than the vertical width of the operating protrusion 62 shown in FIG. It may be something. The end surface 621a of the operating protrusion 62B closest to the indoor side is formed into a substantially flat surface parallel to the indoor side finding surface 34a of the joining stile 34. Therefore, even if the vertical width of the operation protrusion 62 is increased, the amount of protrusion toward the indoor side is suppressed.

The operation protrusion may be formed in a thin plate shape that protrudes toward the indoor side, like the operation protrusion 62C of the operation section 6C shown in FIG. The tip 622 of the operating projection 62C is slightly bent upward. This makes it easier for the elbow EL to rest on the operating protrusion 62C, improving the operability of the operating section 6 by the elbow EL.

The operation protrusions may be arranged at both upper and lower ends 611 of the operation section main body 61, like the operation protrusion 62D of the operation section 6D shown in FIG. 15. The operating projections 62D are plate-shaped members that project toward the indoor side from both upper and lower ends 611 of the operating section main body 61, respectively. The operation protrusion 62D stands up substantially perpendicularly to the indoor side finding surface 34a of the joining frame 34. The position of the tip of the operation protrusion 62D on the indoor side is approximately equal to the position of the central part 612 that protrudes most toward the indoor side. Since the tip edge of the operation protrusion 62D is formed in an arc shape, the operator OP is unlikely to feel uncomfortable even if the operator OP touches the elbow EL during operation.

The operating protrusions made of plate-like members disposed at the upper and lower ends 611 of the operating unit main body 61 respectively have a protruding amount toward the indoor side, like the operating protrusions 62E of the operating unit 6E shown in FIG. It may be formed even smaller. Since the amount of protrusion of the operation protrusion 62E toward the indoor side is suppressed, it is possible to suppress the operator OP's elbow EL from unintentionally colliding with the operation protrusion 62E.

The operation protrusions disposed at the upper and lower ends 611 of the operation section main body 61 may be formed by minute convex parts, like the operation protrusion 62F of the operation section 6F shown in FIG. 17. The amount of protrusion of the operation protrusion 62E toward the indoor side can be further suppressed, and the operation section 6 can have a neat appearance, so that the appearance is improved.
