[0009] (First Embodiment) As shown in Figure 1, the joinery 1 according to this embodiment is a vertical sliding window installed in an opening 11 in a wall that separates the interior and exterior. The horizontal direction along the wall is referred to as the width direction. In the drawing, the width direction is indicated by arrow X. The horizontal direction perpendicular to the width direction is referred to as the interior / exterior direction. In the drawing, the interior / exterior direction is indicated by arrow Y. In the drawing, the vertical direction perpendicular to both the width direction and the interior / exterior direction is indicated by arrow Z.

[0010] The construction tool 1 has a frame body 21, a shoji 22, and a shoji opening / closing device 3. The frame body 21 is provided along the opening 11. The shoji 22 is provided inside the frame body 21. The shoji 22 is a vertically sliding window. The frame body 21 supports the shoji 22 so as to be movable in the width direction and rotatable about an axis extending in the vertical direction. The shoji 22 opens and closes the opening 11 by rotating about the axis while moving in the width direction with respect to the frame body 21. The state in which the shoji 22 closes the opening 11 is referred to as the closed state. The state in which the shoji 22 opens the opening 11 is referred to as the open state.

[0011] The frame body 21 is a rectangular four-sided frame. The frame body 21 has a lower frame 211 and an upper frame 212 extending in the width direction, and a first vertical frame 213 and a second vertical frame 214 extending in the vertical direction. The first vertical frame 213 is disposed on one side in the width direction of the second vertical frame 214. The first vertical frame 213 faces the door end frame 221 of the shoji 22. The second vertical frame 214 faces the hanging end frame 222 of the shoji 22.

[0012] As shown in FIGS. 2 and 3, the shoji opening / closing device 3 has a shoji opening / closing part 31 and a locking / unlocking device 32. The shoji opening / closing part 31 moves the shoji 22 to open and close the opening 11. The locking / unlocking device 32 switches between a state in which the movement of the shoji 22 in the closed state is restricted and a state in which the shoji 22 is movable. The state in which the movement of the shoji 22 in the closed state is restricted is referred to as the locked state. The state in which the shoji 22 is movable is referred to as the unlocked state.

[0013] The unlocking device 32 includes a lock part 4, an operation part 5, a time difference driving part 6, an operation connection part 7, a lock connection part 8, a direction conversion part 9, an operation support part 75, an unlocking support part 85, and a direction conversion support part 95. The lock part 4 is provided on the first vertical frame 213. When in the locked state, the lock part 4 restrains the shoji 22 that closes the opening 11, and when in the unlocked state, it allows the movement of the shoji 22. The operation part 5 is provided on the lower frame 211. The lower frame 211 is the horizontal frame in the claims. The operation part 5 operates both the unlocking and locking by the unlocking device 32 and the movement of the shoji 22 by the shoji opening / closing part 31. The operation part 5 of the unlocking device 32 also serves as the operation part of the shoji opening / closing part 31. The time difference driving part 6 drives the unlocking and locking by the unlocking device 32 and the movement of the shoji 22 by the shoji opening / closing part 31 with a time difference.

[0014] When the operation part 5 is operated so that the time difference driving part 6 changes from the closed and locked state to the open and unlocked state, first, the unlocking device 32 is driven to change from the locked state to the unlocked state, and then the shoji opening / closing part 31 is driven to change from the closed state to the open state. When the operation part 5 is operated so that the time difference driving part 6 changes from the open and unlocked state to the closed and locked state, first, the shoji opening / closing part 31 is driven to change from the open state to the closed state, and then the unlocking device 32 is driven to change from the unlocked state to the locked state. Details of the operation part 5 and the time difference driving part 6 will be described later.

[0015] As shown in Figures 2 to 4, the operating connection part 7 is provided on the lower frame 211. The operating connection part 7 is connected to the operating part 5. The operating connection part 7 moves in the width direction relative to the lower frame 211 by operation of the operating part 5. The operating support part 75 is fixed to the lower frame 211. The operating support part 75 supports the operating connection part 7 so that it can move in the width direction. The locking connection part 8 is provided on the first vertical frame 213. The locking connection part 8 is connected to the lock part 4. The locking connection part 8 switches between the locked and unlocked states of the lock part 4 by moving in the vertical direction. The locking / unlocking support part 85 is fixed to the first vertical frame 213. The locking / unlocking support part 85 supports the locking connection part 8 so that it can move in the vertical direction. The direction changing part 9 is provided between the operating connection part 7 and the locking connection part 8 at the corner between the lower frame 211 and the first vertical frame 213. The direction changing section 9 is movable vertically relative to the frame 21. When a force in the width direction is transmitted to the direction changing section 9 due to the widthwise displacement of the operating coupling section 7, the direction changing section 9 converts the force in the width direction into a vertical force and transmits it to the lock coupling section 8. The direction changing support section 95 is fixed to the corner between the lower frame 211 and the first vertical frame 213. The direction changing support section 95 supports the direction changing section 9 so that it can move vertically.

[0016] The locking mechanism 4 shown in Figures 1 and 2, when closed, protrudes toward the door frame and hooks onto the door frame 221, restraining the movement of the sliding door 22 and thus locking it. When unlocked, it separates from the door frame 221 and allows the sliding door 22 to move.

[0017] When the operating unit 5 of the locking / unlocking device 32 is operated from the locked state shown in Figure 4 to the unlocked state shown in Figure 5, the operating coupling unit 7 moves to one side in the width direction relative to the lower frame 211, that is, the side closer to the first vertical frame 213. The direction changing unit 9 converts the force transmitted in the width direction that is transmitted by the movement of the operating coupling unit 7 to one side in the width direction into an upward force, and moves the lock coupling unit 8 upward. As the lock coupling unit 8 moves upward, the lock part 4 becomes unlocked. When the operating unit 5 of the locking / unlocking device 32 is operated from the unlocked state shown in Figure 5 to the locked state shown in Figure 4, the operating coupling unit 7 moves to the other side in the width direction relative to the lower frame 211, that is, the side away from the first vertical frame 213. The direction changing unit 9 converts the force transmitted in the width direction that is transmitted by the movement of the operating coupling unit 7 to the other side in the width direction into a downward force, and moves the lock coupling unit 8 downward. As the lock connecting part 8 moves downward, the lock part 4 becomes locked.

[0018] As shown in Figures 3, 4, and 6, the operating connection section 7 includes a first operating connection member 71, a second operating connection member 72, and a third operating connection member 73.

The flat plate section 955 is formed in a flat plate shape. The flat plate section 955 is positioned so that its plate surface faces the indoor / outdoor direction. The block section 956 is connected to one side of the flat plate section 955 in the width direction. The block section 956 is block-shaped and has larger dimensions in the indoor / outdoor direction than the flat plate section 955. The block section 956 protrudes outward from the flat plate section 955.

[0028] A groove 957 extending across the entire width is formed at the outdoor end of the block portion 956. The groove 957 is recessed on the indoor side and opens on the outdoor side. The third operating connecting member 73 of the operating connecting portion 7 is slidably positioned in the width direction within the groove 957. The front plate portion 954 is fixed to the outdoor side of the block portion 956. The third operating connecting member 73 is sandwiched between the block portion 956 and the front plate portion 954. The protrusion 732 of the third operating connecting member 73 is positioned on one side in the width direction of the block portion 956.

The other side of the third operating connecting member 73 in the width direction, that is, the side connected to the second operating connecting member 72, is positioned on the other side in the width direction of the block portion 956.

[0029] The first protrusion 952 projects outwards from the upper side of the flat plate portion 955. The second protrusion 953 projects outwards from the lower side of the flat plate portion 955. The first protrusion 952 and the second protrusion 953 are spaced apart in the vertical direction. A direction changing section 9 is positioned on the outdoor side of the flat plate portion 955. The first protrusion 952 is inserted into the first groove 93 of the direction changing section 9. The outer diameter of the first protrusion 952 is slightly smaller than the groove width of the first groove 93. The second protrusion 953 is inserted into the second groove 94 of the direction changing section 9. The outer diameter of the second protrusion 953 is slightly smaller than the groove width of the second groove 94. The direction changing section 9 is movable vertically relative to the direction changing support section 95 with the first protrusion 952 inserted into the first groove 93 and the second protrusion 953 inserted into the second groove 94.

[0030] As shown in Figures 10 and 11, the protrusion 732 of the third operating connecting member 73 is inserted from the outside into the direction changing groove 91 of the direction changing section 9, which is supported by the direction changing support section 95 so as to be movable in the vertical direction. When the unit is locked and the operating connecting section 7 is positioned on the other side in the width direction within its movable range, the protrusion 732 of the operating connecting section 7 is positioned at the first position 914 of the direction changing groove 91, i.e., at the other end in the width direction of the upper groove 911. The first protrusion 952 of the direction changing support section 95 is positioned at the upper end of the first groove 93 of the direction changing section 9. The second protrusion 953 of the direction changing support section 95 is positioned at the upper end of the second groove 94 of the direction changing section 9.

[0031] When the operating unit 5 is operated from the locked state to the unlocked state, and the operating connection unit 7 moves to one side in the width direction, the protrusion 732 of the operating connection unit 7 reaches the second position 915 of the direction change groove unit 91. When the operating connection unit 7 moves further to one side in the width direction, the protrusion 732 enters the intermediate inclined groove unit 912 and pushes the upper edge 912a of the intermediate inclined groove unit 912 to one side in the width direction. The direction change unit 9 cannot move in the width direction relative to the direction change support unit 95, but can move in the vertical direction. Therefore, the direction change unit 9 moves upward as if pushed up by the protrusion 732. When the operating connection unit 7 moves further to one side in the width direction, the protrusion 732 reaches the third position 916 of the direction change groove unit 91. The first protrusion 952 of the direction change support unit 95 is positioned at the lower end of the first groove unit 93 of the direction change unit 9. The second protrusion 953 of the direction change support portion 95 is positioned at the lower end of the second groove portion 94 of the direction change portion 9. Furthermore, when the operating coupling portion 7 moves to the other side in one direction, the protrusion 732 enters the lower groove portion 913 and moves to one side in the width direction, positioning itself at the fourth position 917 of the direction change groove portion 91.

[0032] When the projection 732 of the direction changing section 9 is positioned at the fourth position 917, the projection 732 moves upward from the locked state where it is positioned at the first position 914. As the direction changing section 9 moves upward, the lock connecting section 8 moves upward, and the lock section 4 becomes unlocked. In the unlocked state, the projection 732 is positioned at the fourth position 917 of the direction changing groove section 91. The first projection 952 of the direction changing support section 95 is positioned at the lower end of the first groove section 93 of the direction changing section 9. The second projection 953 of the direction changing support section 95 is positioned at the lower end of the second groove section 94 of the direction changing section 9.

[0033] When the operating unit 5 is operated from the unlocked state to the locked state, and the operating connecting unit 7 moves to the other side in the width direction, the protrusion 732 of the operating connecting unit 7 reaches the third position 916 of the direction changing groove 91. When the operating connecting unit 7 moves further to the other side in the width direction, the protrusion 732 enters the intermediate inclined groove 912 and pushes the lower edge 912b of the intermediate inclined groove 912 to the other side in the width direction. The direction changing unit 9 moves downward as if pushed down by the protrusion 732. When the operating connecting unit 7 moves further to the other side in the width direction, the protrusion 732 reaches the second position 915 of the direction changing groove 91. The first protrusion 952 of the direction changing support unit 95 is positioned at the upper end of the first groove 93 of the direction changing unit 9. The second protrusion 953 of the direction changing support unit 95 is positioned at the upper end of the second groove 94 of the direction changing unit 9. Furthermore, as the operating coupling portion 7 moves to the other side in the width direction, the protrusion 732 enters the upper groove portion 911 and moves to the other side in the width direction, positioning itself at the first position 914 of the direction changing groove portion 91. As the direction changing portion 9 moves downward, the lock coupling portion 8 moves downward, and the lock portion 4 becomes locked.

[0034] As shown in Figures 12 and 13, the operating unit 5 includes a handle 51, a gear 52, an arm 53, a shaft 54, and a case 55. The handle 51 and case 55 are shown in Figure 1. The handle 51 is grasped and operated by the user. The handle 51 is, for example, an operator handle. The gear 52 rotates in conjunction with the operation of the handle 51, moving the operating coupling 7 in the width direction. The arm 53 rotates in conjunction with the rotation of the gear 52, opening and closing the sliding door 22. The gear 52 and arm 53 rotate around a rotation axis 5a that extends in the vertical direction when the handle 51 is operated. This rotation axis 5a is the axis of the shaft 54. The direction around the axis of the shaft 54, i.e., the rotation axis 5a, is referred to as the circumferential direction. Of the circumferential directions, the front side in the clockwise direction when viewed from above is referred to as one side, and the rear side in the clockwise direction is referred to as the other side. The shaft portion 54 is cylindrical in shape and extends in the vertical direction.

[0035] Case 55 houses the handle 51, gear 52, arm 53, and shaft 54. Case 55 is fixed to the lower frame 211. The indoor plate portion 215 on the indoor side of the lower frame 211 has an opening that penetrates in the indoor-outdoor direction. Refer to Figure 3 for the indoor plate portion 215. The gear 52 and arm 53 penetrate the opening and are positioned across the indoor and outdoor sides of the indoor plate portion 215. The handle 51, shaft 54, and case 55 are positioned on the indoor side of the indoor plate portion 215.

[0036] The shaft portion 54 is formed in a cylindrical shape that extends vertically. An upper plate portion 542 is connected to the upper end of the shaft portion 54. The upper plate portion 542 is a disc-shaped member with a larger diameter than the shaft portion 54. The upper plate portion 542 is connected coaxially to the upper end of the shaft portion 54. A lower plate portion 543 is connected to the lower end of the shaft portion 54. The lower plate portion 543 is an annular plate-shaped member with an outer diameter larger than the shaft portion 54 and an inner diameter the same as the outer diameter of the shaft portion 54. The lower end of the shaft portion body 541 is fitted inside the lower plate portion 543. The upper plate portion 542 and the lower plate portion 543 are also housed in the case 55.

[0037] When the operating unit 5 is operated to unlock the sliding door 22 from the locked state and open it, the gear 52 and arm 53 rotate clockwise around one side in the circumferential direction, i.e., around the rotation axis 5a when viewed from above. When the operating unit 5 is operated to close the sliding door 22 from the unlocked state and lock it, the gear 52 and arm 53 rotate counterclockwise around the rotation axis 5a when viewed from above, i.e., around the rotation axis 5a when viewed from above. The time-delay drive unit 6 is composed of an elongated hole 527 formed in the gear 52 and an arm projection 534 provided on the arm 53.

[0038] As shown in Figure 13, the gear 52 has a gear plate portion 521 and a gear projection portion 522. The gear plate portion 521 is a flat plate-shaped member with a plurality of teeth 523 formed on its outer circumference. The plurality of teeth 523 are formed on a part of the outer circumference of the gear plate portion 521. The portion of the outer circumference of the gear plate portion 521 where the plurality of teeth 523 are formed is referred to as the tooth-shaped portion 524. The portion of the outer circumference of the gear plate portion 521 where the plurality of teeth 523 are not formed is referred to as the non-tooth-shaped portion 525.

[0039] The gear plate portion 521 has an axial hole portion 526 formed approximately in the center of the plate surface through which the shaft portion 54 passes. The gear plate portion 521 is arranged with the plate surface in a horizontal direction, and the axial hole portion 526 passes through in the vertical direction. The gear plate portion 521 has an arc-shaped elongated hole portion 527 that penetrates the plate surface and extends in the circumferential direction on the outer circumference side of the axial hole portion 526. The portion of the edge of the elongated hole portion 527 located at the other end in the circumferential direction is denoted as the first edge portion 527a. The portion of the elongated hole portion 527 located at one end in the circumferential direction is denoted as the second edge portion 527b.

[0040] The gear projection 522 protrudes downward from the circumferential middle portion of the non-tooth-forming portion 525 of the gear plate portion 521. The gear 52 is positioned such that the side with the gear projection 522 is on the outdoor side and the tooth-forming portion is on the indoor side. The gear projection 522 is positioned on the outdoor side of the indoor plate portion 215 of the lower frame 211. The gear projection 522 is positioned in the gear projection insertion portion 714 of the first operating connecting member 71 of the operating connecting portion 7, i.e., the gear projection insertion portion 714.

[0041] The arm 53 has a gear connection portion 531 and a sliding door connection portion 532. The gear connection portion 531 receives the rotation of the gear 52. The sliding door connection portion 532 is connected to the sliding door 22. The gear connection portion 531 has a disc-shaped disc portion 533 and an arm projection portion 534 that protrudes from the disc portion 533. The disc portion 533 has an axial hole portion 535 formed in its central part through which the shaft portion 54 passes. The disc portion 533 is arranged so that its plate surface is in the vertical direction. The arm projection portion 534 protrudes downward from the lower surface of the disc portion 533. In the gear connection portion 531, the disc portion 533 overlaps the gear plate portion 521, and the arm projection portion 534 is inserted from above into the elongated hole portion 527 of the gear plate portion 521. The shaft portion 54 penetrates both the shaft hole 526 of the gear plate portion 521 and the shaft hole 535 of the gear connector portion 531, supporting the gear 52 and arm 53 so that they can rotate coaxially. The upper plate portion 542 of the shaft portion 54 is positioned above the gear connector portion 531. The lower plate portion 543 of the shaft portion 54 is positioned below the gear plate portion 521.

[0042] The shoji screen connecting portion 532 is a long, plate-like structure. The shoji screen connecting portion 532 is positioned with its plate surface facing vertically. One end 532a of the shoji screen connecting portion 532 is connected to the gear connecting portion 531. The gear connecting portion 531 and the shoji screen connecting portion 532 are integrally formed. The other end 532b of the shoji screen connecting portion 532 is connected to the shoji screen 22 so as to be rotatable relative to it around an axis extending in the vertical direction. The shoji screen connecting portion 532 is positioned on the outdoor side of the indoor plate portion 215 of the lower frame 211.

[0043] The circumferential dimension of the arm projection 534 is smaller than the circumferential dimension of the elongated hole 527 of the gear plate 521. The arm projection 534 is movable in the circumferential direction inside the elongated hole 527. When the gear 52 rotates to one side in the circumferential direction, if the first edge 527a of the elongated hole 527 contacts the arm projection 534 from one side in the circumferential direction, the arm projection 534 is pushed by the first edge 527a of the gear 52 and rotates to the same side in the circumferential direction, causing the arm 53 to rotate to the same side in the circumferential direction together with the gear 52. When the gear 52 rotates to the other side in the circumferential direction, if the second edge 527b of the elongated hole 43 contacts the arm projection 534 from the other side in the circumferential direction, the arm projection 534 is pushed by the second edge 527b of the gear 52 and rotates to the same side in the circumferential direction, causing the arm 53 to rotate to the same side in the circumferential direction together with the gear 52. Even if the gear 52 rotates, the arm 53 will not rotate with the gear 52 unless the arm projection 534 of the arm 53 is pressed against either the first edge 527a or the second edge 527b of the gear 52 as described above.

[0044] In the locked and closed states shown in Figure 14, the arm projection 534 is positioned at one end of the elongated hole 527 in the circumferential direction and is separated from the first edge 527a of the elongated hole 527. The gear projection 522 is positioned in the gear projection insertion portion 714. When the operating unit 5 is operated to unlock from the locked state and open the sliding door 22, the gear 52 rotates to one side in the circumferential direction. Because the arm projection 534 is separated from the first edge 527a of the elongated hole 527, the arm 53 does not rotate until the arm projection 534 contacts the first edge 527a of the elongated hole 527. As the gear 52 rotates, the gear projection 522 moves to one side in the width direction. The gear projection 522 that has moved to one side in the width direction contacts the first projection piece 712.

[0045] As shown in Figure 15, when the operating unit 5 is operated to further open the sliding door 22, the gear 52 rotates and the gear projection 522 moves to one side in the width direction. The gear projection 522 pushes the first projection piece 712 to one side in the width direction, and pushes the operating coupling unit 7 to one side in the width direction. The operating coupling unit 7 is pushed to one side in the width direction, resulting in the unlocked state. When the gear projection 522 rotates to one side in the circumferential direction, it moves to one side in the width direction and also moves towards the indoor side, so it comes out of the gear projection insertion part 714. When the gear projection 522 comes out of the gear projection insertion part 714, the operating coupling unit 7 is no longer pushed by the gear projection 522, and the movement of the operating coupling unit 7 stops. The operating coupling unit 7 stops in the unlocked position. When the gear projection 522 rotates to a position where it is disengaged from the gear projection insertion portion 714, the arm projection 534 comes into contact with the first edge 527a of the elongated hole portion 527.

[0046] As shown in Figure 16, when the operating unit 5 is operated to further open the sliding door 22, the arm projection 534 is pushed against the first edge 527a of the elongated hole 527, causing the arm 53 to rotate to one side in the circumferential direction together with the gear 52. This opens the sliding door 22. In the unlocked and open states, the arm projection 534 is positioned at the other end of the elongated hole 527 in the circumferential direction and is separated from the second edge 527b of the elongated hole 527.

[0047] When the operating unit 5 is operated to close and lock the sliding door 22 from the unlocked state, the gear 52 rotates to the other side in the circumferential direction. When the second edge 527b of the elongated hole 527 contacts the arm projection 534, the arm 53 rotates to the other side in the circumferential direction together with the gear 52, and the sliding door 22 closes. The gear projection 522 of the gear 52 enters the gear projection insertion part 714 and rotates to the other side in the circumferential direction while pushing the second protruding piece 713 to the other side in the width direction. The operating coupling part 7, with the second protruding piece 713 pushed to the other side in the width direction by the gear projection 522, moves to the other side in the width direction and enters the locked state.

[0048] In the door 1 and locking / unlocking device 32, when a force in the width direction is transmitted to the direction changing section 9 by the widthwise displacement of the operating connection section 7, the force in the width direction is converted into a force in the vertical direction, and the locking connection section 8 moves vertically, thereby locking and unlocking the lock section 4. The structure that converts the force in the width direction transmitted to the direction changing section 9 into a vertical force is a simple structure consisting of a direction changing groove 91 formed in the direction changing section 9 and a protrusion 732 provided on the operating connection section 7. The locking / unlocking device 32 can be made into a simple structure, and the number of parts in the door 1 and locking / unlocking device 32 can be reduced.

[0049] Since the protrusion 732 provided on the operating connection part 7 is movable along the direction changing groove 91 formed on the direction changing part 9, the direction of relative displacement between the direction changing part 9 and the protrusion 732 is stabilized. The direction changing part 9 can reliably convert the force in the width direction transmitted by the width direction displacement of the operating connection part 7 into a force in the vertical direction.

[0050] The operating connection section 7 is composed of multiple members, including a first operating connection member 71, a second operating connection member 72, and a third operating connection member 73, with at least one of these members being interchangeably connected. When adjusting the widthwise length of the operating connection section 7, for example, the widthwise length of the operating connection section 7 can be easily adjusted by replacing the second operating connection member 72 with another member having a different widthwise length. Even if the operating connection sections 7 have different widthwise lengths, there are many common parts, making manufacturing and management easier.

[0051] The lock connecting section 8 is composed of multiple components, including a first lock connecting member 81, a second lock connecting member 82, and a third lock connecting member 83, with at least one of these components interchangeably connected. When adjusting the vertical length of the lock connecting section 8, for example, the second lock connecting member 82 can be easily adjusted by replacing it with another component having a different vertical length. Even with lock connecting sections 8 having different vertical lengths, there are many common parts, making manufacturing and management easier.

[0052] The time-delay drive unit 6 is provided on the operating unit 5. The elongated hole 527 formed in the gear 52 and the arm projection 534 provided on the arm 53 constitute the time-delay drive unit 6. The locking / unlocking device 32 of this embodiment can reduce the number of parts compared to the case in which the time-delay drive unit 6 is provided separately from the operating unit 5.

[0053] The locking / unlocking device 32 is provided with an operating support part 75 that supports the operating coupling part 7 so that it can move in the width direction. The operating coupling part 7 can be moved stably and smoothly in the width direction. The force in the width direction generated by the movement of the operating coupling part 7 in the width direction can be reliably transmitted to the direction changing part 9.

[0054] The locking / unlocking device 32 is provided with a locking / unlocking support part 85 that supports the lock connecting part 8 so that it can move vertically. The lock connecting part 8 can be moved stably and smoothly in the vertical direction. Because the lock connecting part 8 can move reliably in the vertical direction, the lock part 4 can be reliably locked and unlocked.

[0055] The locking / unlocking device 32 is provided with a direction-changing support part 95 that supports the direction-changing part 9 so that it can move vertically. The locking / unlocking device 32 can be moved stably and smoothly in the vertical direction. Because the direction-changing part 9 moves reliably in the vertical direction, the lock part 4 can be reliably locked and unlocked via the lock connecting part 8.

[0056] (Second Embodiment) The locking / unlocking device 32B according to the second embodiment shown in Figure 17 employs a rack and pinion in the operating coupling section 7B. The operating coupling section 7B has a first rack section 761, a second rack section 762, and a pinion 763. The first rack section 761 extends in the width direction. The first rack section 761 moves in the width direction by operation of the operating section 5. The second rack section 762 extends in the width direction. The second rack section 762 is provided with a protrusion 732B that is inserted into the direction changing groove section 91B of the direction changing section 9B. The pinion 763 is provided between the first rack section 761 and the second rack section 762.

[0057] When the operating unit 5 is operated from the locked state shown in Figure 17 to the unlocked state shown in Figure 8, the first rack unit 761 moves to the other side in the width direction, and the second rack unit 762 moves to one side in the width direction. The direction changing groove 91B of the direction changing unit 9B is formed in a shape that is symmetrical in the width direction to the direction changing groove 91 of the direction changing unit 9 of the first embodiment. When the second rack unit 762 moves to one side in the width direction, the direction changing unit 9B moves upward. When the direction changing unit 9B moves upward, the lock connecting unit 8 moves upward, and the lock unit 4 becomes unlocked.

[0058] When the operating unit 5 is operated from the unlocked state shown in Figure 18 to the locked state shown in Figure 17, the first rack unit 761 moves to one side in the width direction, and the second rack unit 762 moves to the other side in the width direction. When the second rack unit 762 moves to the other side in the width direction, the direction changing unit 9B moves downward. When the direction changing unit 9B moves downward, the lock connecting unit 8 moves downward, and the lock unit 4 becomes locked.

[0059] In the locking / unlocking device 32B, a rack and pinion system is employed in the operating coupling section 7, which ensures that the force generated by the movement of the operating coupling section 7B in the width direction is reliably transmitted to the direction changing section 9B.

[0060] This disclosure is not limited to the embodiments described above and can be modified as appropriate. For example, a protrusion may be formed on the direction changing section 9 instead of the operating connecting section 7, a direction changing groove may be formed on the operating connecting section 7 instead of the direction changing section 9, and the protrusion of the direction changing section 9 may be inserted into the direction changing groove of the operating connecting section 7. The locking section 4 and the locking connecting section 8 may be provided on the second vertical frame 214. The operating section 5 and the operating connecting section 7 may be provided on the upper frame 212. The locking section 4 and the locking connecting section 8 may be provided on the lower frame 211 or the upper frame 212, and the operating section 5 and the operating connecting section 7 may be provided on the first vertical frame 213 or the second vertical frame 214.

[0061] The intermediate inclined groove 912 of the direction-changing groove 91 extends in a straight line, but it may also extend in a curved shape.

[0062] The locking / unlocking device 32 may, instead of changing the direction of force by inserting a protrusion 732 provided on the operating coupling part 7 into a direction changing groove 91 formed in the direction changing part 9 and moving, change the direction of force by contacting a part of the operating coupling part 7 or a member attached to the operating coupling part 7 with a guide portion extending diagonally provided on the direction changing part 9 and moving.

[0063] The operating connection part 7 may be a single component. This reduces the number of parts. The lock connection part 8 may also be a single component. This reduces the number of parts.

[0064] The time-delay drive unit 6 may be provided separately from the operating unit 5. For example, the time-delay drive unit 6 may be provided between the operating unit 5 and the direction-changing unit 9. By providing the time-delay drive unit 6 between the operating unit 5 and the direction-changing unit 9, it is easier to transmit the operation of the operating unit 5 to the time-delay drive unit 6, and also easier to transmit the driving force from the time-delay drive unit 6 to the direction-changing unit 9. The configurations of the operating unit 5 and the time-delay drive unit 6 may be other than those described above.

[0065] The operating support portion 75 that supports the operating connection portion 7 so as to be movable in the width direction may be of a different form than described above. If the operating connection portion 7 can move stably in the width direction, the operating support portion 75 may not be provided. The locking / unlocking support portion 85 that supports the lock connection portion 8 so as to be movable in the vertical direction may be of a different configuration than described above. If the operating connection portion 7 can move stably in the vertical direction, the locking / unlocking support portion 85 may not be provided. The direction changing support portion 95 that supports the direction changing portion 9 so as to be movable in the vertical direction may be of a different form than described above. If the direction changing portion 9 can move stably in the vertical direction, the direction changing support portion 95 may not be provided.

[0066] The operating direction of the control unit 5, the direction in which the gear 52 and arm 53 rotate, and the direction in which the sliding door 22 opens and closes may be other than those described above and may be set as appropriate. The positions in which multiple teeth 523 are formed on the gear 52, the positions in which the gear protrusion 522 is provided, and the orientation and posture of the gear 52 may be set as appropriate.
