  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the invention, its scope of application, or its application.

(Constitution)
In FIG. 1, a sliding door frame 1 is provided in a left-opening sliding door device 5, and the sliding door frame 1 is a vertical frame on the door end side and the door bottom side that is erected on the left and right sides with a space between each other. 11 and 11 and the vertical frame 11, which is spanned between the upper ends of the vertical frames 11 and 11 and connected and fixed in the horizontal direction, and the central portion between the vertical frames 11 and 11 are spaced apart from each other in the thickness of the door pocket. Are installed in parallel with the upper ends thereof, and neutral stands 13 and 13 which are connected and fixed to the head 12 at the upper end. A wall material 14 is provided on the front side of the front side neutral frame 13, the front side of the duck 12, and the right door butt side vertical frame 11. Wall materials 15 are fixed to the rear surface by screws or the like (not shown). Thereby, the door pocket 16 is formed between the wall materials 14 and 15, and the door-end side opening 16 a of the door pocket 16 is formed between the neutral stands 13 and 13. In the present disclosure, the thickness direction of the door pocket refers to the thickness direction of the door pocket facing the wall materials 14, 15, the front direction from the wall material 15 toward the wall material 14, and the rear direction from the wall material 14 to the wall material 15. It shall point in the direction towards

  The trigger device 2 is attached to a rail groove 12a formed on the lower surface of the Kamoi 12 and has an upper suspension rail 21 as a rail that supports a sliding door 51 of a sliding door device 5 described later so as to be slidable in the left-right direction, A plate receiving pedestal 31 configured to be integrally attached and a trigger plate 41 configured to be locked and fixed to the plate receiving pedestal 31 are provided. In the present disclosure, the door end side refers to the door end side of the sliding door 51 (left side in the case of a left opening sliding door), and the door end side refers to the door bottom side of the sliding door 51 (in the case of a left opening sliding door, the right side). Shall point to.

  As shown in FIG. 2, the upper suspension rail 21 is made of, for example, aluminum metal whose outer shape is formed in a substantially rectangular shape in cross-sectional view by extrusion molding or the like, and includes a pair of side walls 21a and 21a facing each other and the side walls 21a and 21a. The upper wall 21b integrally connecting the upper ends and lower walls 21c and 21c extending inward in the horizontal direction from the lower ends of the side walls 21a and 21a, respectively. A notch 21d extending in the entire longitudinal direction is formed therebetween. In addition, a guide groove 21e is formed in the upper wall 21b of the upper suspension rail 21 so as to extend over the entire longitudinal direction so that the trigger plate 41 can be guided to the plate receiving base 31 when the trigger plate 41 is attached. Further, the upper wall 21b of the upper suspension rail 21 is formed with screw holes 21g, 21g,... For fixing the upper suspension rail 21 to the lower surface of the duck 12 at a predetermined pitch. On the door end side, screw holes 21h and 21h for fixing the door end side end of the trigger plate 41 to be described later to the head 12 are formed.

  The door end side end portion of the upper suspension rail 21 is cut and separated, and only the cut portion 22 cut from the head 12 is configured to be attachable / detachable. Thus, even after the upper suspension rail 21 is attached to the head 12, the slide assist mechanism 61 described later can be attached to and detached from the upper suspension rail 21 by removing only the cutting portion 22. Further, two screw holes 21i and 21i are formed in the upper wall 21b of the upper suspension rail 21 in the longitudinal direction at a position on the door bottom side from the cutting portion 22, and the slide assist mechanism 61 is operated when the sliding door 51 is closed. The closing operation trigger 23 for starting the slide assist operation is fixed to the head 12 from the lower surface of the upper suspension rail 21 through the screw holes 21i and 21i.

  Further, the upper wall 21b of the upper suspension rail 21 is formed with a rectangular through hole 21f as a mounting portion penetrating in the vertical direction at the mounting position of the plate receiving base 31 (a fixed position from the door end side end). ing. The mounting portion is not limited to the through hole. For example, the upper suspension rail 21 is formed with a groove or recess that is slightly larger than the outer shape of the plate receiving base 31, and the plate receiving base 31 is fitted into the groove or recess. 21 may be configured so as to be attached to the Kamoi 12 integrally.

  As shown in FIG. 3, the plate receiving base 31 is a rectangular plate made of, for example, steel, and has an outer shape slightly smaller than the outer shape of the through hole 21 f of the upper suspension rail 21. In addition, screw holes 31a and 31a are formed in the longitudinal direction in the central portion of the plate receiving base 31 in the width direction. As a result, the plate receiving base 31 is fitted into the through hole 21 f and can be attached to the head 12 integrally with the upper suspension rail 21. Thus, since the plate receiving base 31 is fitted into the through hole 21f of the upper suspension rail 21 and can be attached integrally with the upper suspension rail 21, the influence of the thickness of the plate receiving base 31 is more effectively affected. Can be reduced. Thereby, compared with the case where the through-hole 21f is not provided, it becomes possible to set the height of the upper suspension rail 21 low, and the upper suspension rail 21 can be reduced in size. Although the function of the plate receiving base 31 may be integrated with the upper suspension rail 21, the thickness (the size in the height direction) of the upper suspension rail 21 is increased by the amount of the structure for locking the plate receiving base 31, and the size is reduced. Is difficult. That is, the upper suspension rail 21 can be reduced in size by separately configuring the plate receiving base 31 and the upper suspension rail 21 as separate members. With this downsizing, the upper suspension rail 21 can be used not only for a retractable door with a door pocket but also for a single sliding door without a door pocket. Moreover, the plate receiving base 31 and the upper suspension rail 21 can be made of different materials by configuring the plate receiving base 31 and the upper suspension rail 21 as separate members. For example, as in the present embodiment, a material with high workability (for example, aluminum metal) is selected for the upper suspension rail 21 and a hard material (for example, steel) is selected for the plate receiving base 31, thereby securing the locking strength. However, the upper suspension rail 21 and the plate receiving base 31 can be reduced in size.

  Further, a pair of L-shaped side surfaces formed by bending the projecting pieces downward and then inward at both ends in the width direction of the plate receiving base 31 (the left-right direction in FIGS. 3B and 3C), respectively. While the support portions 32 and 33 are provided, an end support portion 34 formed by bending a protruding piece downward is provided at one end portion in the longitudinal direction (vertical direction in FIG. 3B). The pair of side surface support portions 32 and 33 are displaced from each other in the longitudinal direction, facilitating guidance when the trigger plate 41 is attached. A rectangular plate insertion hole 34 a penetrating in the longitudinal direction is formed in the center portion in the width direction of the end support portion 34.

  As shown in FIGS. 4 and 5, the trigger plate 41 includes a plate 42 made of, for example, a steel material, and a trigger 43.

  The plate 42 is longer than the distance from the door-end opening 16a of the door pocket 16 to the door-end end of the through hole 21f, and is slightly narrower than the width of the guide groove 21e of the upper suspension rail 21. The base portion 42a continuously extends from one end portion (tip portion) in the longitudinal direction (left-right direction in FIG. 5A), and is narrower than the width of the base portion 42a and the pair of side surface support portions 32. , 33 and an intermediate portion 42b having a slightly narrower width than the distance between the intermediate portion 42b and the end portion of the intermediate portion 42b. It is comprised by the front-end | tip part 42c slightly smaller than the magnitude | size. The tip end portion 42c is configured such that the upper surface thereof is flush with the base portion 42a and the intermediate portion 42b, while the lower surface thereof is configured to be positioned above the base portion 42a and the intermediate portion 42b. Yes. By adopting such a configuration of the tip end portion 42c, the influence of the thickness of the plate insertion hole 34a of the end support portion 34 can be reduced.

  As described above, when the base portion 42a of the plate 42 is configured to be slightly narrower than the width of the guide groove 21e of the upper suspension rail 21, the trigger plate 41 is locked to the plate receiving base 31. The plate 42 is easily guided, and the attachment work is facilitated. Furthermore, the plate 42 is stepped and narrowed from the base part 42a toward the intermediate part 42b, the tip part 42c and the door bottom side. Accordingly, there is a merit that the plate 42 becomes a guide (call-in) for inserting the plate 42 between the side surface support portions 32 and 33 of the plate receiving pedestal 31 and the end support portion 34 and is easily inserted. Further, since the longitudinal positions of the pair of side support portions 32 and 33 are shifted from each other, the plate 42 is slightly horizontal between the longitudinal ends when the trigger plate 41 is locked to the plate receiving base 31. Even if it is inclined so as to be displaced along, the plate 42 is easily guided between the side surface support portions 32 and 33.

  Two long holes 42 d and 42 d extending in the longitudinal direction are formed through the other end of the base portion 42 a of the plate 42, and the plate 42 is formed above the long holes 42 d and 42 d and the upper suspension rail 21. It is fixed to the upper suspension rail 21 and the turret 12 by screws or the like (not shown) through screw holes 21h, 21h formed in the wall 21b. Thus, by making the screw insertion hole for fixing the plate 42 to the head 12 into the long hole 42d, when the processing tolerance of the plate 42 occurs, the holes of the screw holes 21h and 21h to the upper suspension rail 21 are provided. Even when a gap occurs in the opening position, the plate 42 can be securely and easily fixed to the upper suspension rail 21 and the duck 12 by absorbing it.

  As shown in FIG. 4B, round holes 42f and 42f may be formed in the other end of the base portion 42a of the plate 42 instead of the long holes 42d and 42d. Further, the length of the screw or the like may be adjusted so that the plate 42 is fixed only to the upper suspension rail 21 through the long holes 42d and 42d. However, from the viewpoint of securing the fixing strength of the plate 42, the plate 42 is preferably configured to be fixed to the upper suspension rail 21 and the head 12 with screws or the like.

  On the outer periphery of the base part 42a and the intermediate part 42b of the plate 42, a folded part 42e is formed that is folded back in the thickness direction (vertical direction in FIG. 5B). Thereby, there exists a merit which the intensity | strength of the thickness direction of the plate 42 increases.

  It is a central portion in the width direction (vertical direction in FIG. 5 (a)) of the intermediate portion 42b of the plate 42, and at the intermediate portion in the longitudinal direction, the lower surface of the intermediate portion 42b (the front surface in FIG. 5 (a)). A trigger 43 extending in a protruding manner is integrally provided. The trigger 43 includes a core rod 43a formed of a steel material in a columnar shape, and a resin trigger cover 43b formed so as to cover the outer side in the circumferential direction of the core rod 43a. In this way, by covering the outer side in the circumferential direction of the core rod 43a with the trigger cover 43b, it is possible to reduce the generation of impact sound caused by the slide assist mechanism 61 hitting the trigger 43 during the closing operation of the sliding door 51.

  The trigger 43 is attached and fixed to the plate 42 by, for example, inserting an upper end portion thereof (upper end portion in FIG. 5B) into a hole slightly larger than the core rod 43a provided in the plate 42 and caulking. . The trigger 43 may be attached and fixed to the plate 42 by a method other than caulking, such as welding.

  Returning to FIG. 1, the sliding door 51 is supported so as to be slidable in the left-right direction with respect to the upper suspension rail 21, and a slide assist mechanism 61 is provided in the upper suspension rail 21. Specifically, on the upper suspension rail 21, suspension door wheels 52 and 53 are slidably engaged and supported on the left and right sides, respectively, and the suspension door wheels 52 and 53 are respectively the door end side upper end portion and the door bottom side upper end portion of the sliding door 51. It is attached and fixed to the part. As a result, the sliding door 51 is suspended and supported so as to slide in the left-right direction via the upper suspension rail 21 and the suspension door cars 52 and 53 with respect to the Kamoi 12. In other words, the sliding door 51 moves between the open position where the sliding door 51 moves to the right side and is accommodated in the door pocket 16 by the upper suspension rail 21 and the closed position where the sliding door 51 moves to the left side and protrudes from the door pocket 16. It is slidably supported. A guide groove 51a extending over the entire longitudinal direction is formed at the center of the lower edge of the sliding door 51 in the width direction, and a guide 54 fixed to the floor surface between the neutral ridges 13 and 13 is idled in the guide groove 51a. It is fitted. Thereby, the sliding door 51 can be slid between the open position and the closed position without swinging in the thickness direction.

  As shown in FIGS. 7 and 8, the slide assist mechanism 61 is integrally formed along the upper edge of the sliding door 51 on the door bottom side (right side in FIG. 7) of the suspension door wheel 52 provided on the door end side. Is provided. A wheel 67 is provided at the right end portion (door end side end portion) of the slide assist mechanism 61 so as to be engaged between the upper wall 21b and the lower walls 21c, 21c of the upper suspension rail 21. Thereby, the slide assist mechanism 61 slides between the open position and the closed position in accordance with the slide operation of the sliding door 51.

  The slide assist mechanism 61 includes a main body case 64 having a pin groove 64a for guiding the trigger 43 so as to be relatively movable on the upper side, an open-side clamp unit 62 provided on the door-end side, and a closing provided on the door-end side. Side clamp unit 63, coil spring 65 for moving the open side clamp unit 62 and the close side clamp unit 63 by elastic force, and movement of the open side clamp unit 62 or the close side clamp unit 63 when moving And a damper mechanism 66 that performs damping control so that the speed becomes slow. The open side clamp unit 62 and the close side clamp unit 63 have a bilaterally symmetric shape and substantially the same configuration.

  The open-side clamp unit 62 and the close-side clamp unit 63 are each a base 71 and a pair of clamp claws 73 supported so as to be able to swing with respect to the base 71 so as to contact and separate from each other in plan view with a fulcrum 72 as a center. And an operating body 74 disposed at the base between the clamp claws 73, and a push button 75 and a coil spring 76 incorporated in the operating body 74. The specific configuration of the other slide assist mechanism 61 is disclosed in, for example, Patent Document 1 and will not be described in detail.

  The slide assist operation of the slide assist mechanism 61 related to the opening operation when the sliding door 51 slides from the normal state (the state where the sliding door 51 is not in the open position or the closed position) toward the door bottom will be described. The open-side clamp unit 62 is located at the open-side home position 62a (see the broken line in FIG. 8). Further, the closing side clamp unit 63 is located at the closing side home position 63a (see FIG. 8). Each operating body 74 and push button 75 are urged toward the distal end of the clamp pawl 73 by the elastic force of the coil spring 76. Therefore, the pair of clamp claws 73 are always opened by the operating body 74 in directions away from each other, and are maintained in an unclamped state that engages with the inner wall of the main body case 64.

  When the sliding door 51 having the slide assist mechanism 61 is slid and moved toward the open position, the trigger 43 enters the main body case 64 through the pin groove 64a of the main body case 64, and the clamp claw of the open-side clamp unit 62. 73 is reached. Then, the push button 75 at the base of the clamp claw 73 is pushed by the trigger 43, and the pair of clamp claws 73 are displaced toward each other by the action of the operating body 74 to be in a clamped state. Thus, the engagement between the pair of clamp claws 73 and the inner wall of the main body case 64 is released, and the pair of clamp claws 73 are moved from the open-side home position 62a to the center of the main body case 64 in the longitudinal direction by the urging force of the coil spring 65. Is slowly moved under the action of the damper mechanism 66. As the clamp pawl 73 moves, the sliding door 51 moves slowly to the open position.

  Conversely, when the sliding door 51 having the slide assist mechanism 61 is slid from the open position toward the closed position, the coil spring 65 is contracted at the open position, and the pair of clamp claws 73 of the open-side clamp unit 62 are triggered by the trigger 43. Is clamped. When the sliding door 51 is closed, the coil spring 65 extends, and the open-side clamp unit 62 moves to the open-side home position 62a while the trigger 43 is clamped. At the open-side home position 62a, the pair of clamp claws 73 are released in an unclamped state, so that the trigger 43 is separated from the pair of clamp claws 73, and the sliding door 51 is pulled out from the slide assist mechanism 61 in the door tip side direction. And slide toward the closed position.

(Trigger installation work)
