Description

  The present invention relates to a sliding door structure in which when a plurality of sliding door plates are opened and closed, the adjacent sliding door plates move in conjunction with each other.

  For example, in various storage devices such as cabinets and closets, opening and closing of the storage space in the case of a so-called sliding door structure is performed by sliding a sliding door plate provided on the front surface of the device horizontally along the rail.

  In this type of sliding door structure, when multiple sliding door plates are provided, the sliding door plates must be opened and closed separately one by one. A technique that can be moved is disclosed.

  For example, in the sliding door structure described in Patent Document 1, a plurality of rails are attached in parallel to the upper portion of the closet, and a sliding door plate is suspended on each of the upper rails via a runner and a traveling shaft so as to be able to travel. . An interlocking plate is attached to the upper end of one sliding door plate, and the interlocking plate is formed with a groove having a predetermined length with one end opened along the rail direction, and the groove of the interlocking plate attached to the one sliding door plate. Is fitted with a traveling shaft of another sliding door plate adjacent to the sliding door plate.

When one adjacent sliding door plate approaches one sliding door plate and the two adjacent sliding door plates reach a predetermined overlapping degree, the travel axis of the other sliding door plate is the same as that of the one sliding door plate. It fits into the groove part of the interlocking plate and reaches from the groove part opening to the inner part, and thereafter, the two sliding door plates are integrated, and both move together in the same direction. In addition, the interlock is set to move in a predetermined direction when two adjacent sliding door plates reach a predetermined overlapping degree in both the opening and closing operations of the sliding door. Yes. (For example, refer to Patent Document 1, Patent Document 2, and Patent Document 3).

  However, in the sliding door structure of the above-mentioned patent document, since the projections meshing with the interlocking plates corresponding to the sliding door plates themselves are added and interlocked with each other by the meshing, the interlocking plates and the projections etc. are set so as to mesh well. Must. For this reason, the structure of a sliding door board and an interlocking board is complicated.

  In the sliding door structure, there is a difference in height between the vicinity of the runner that supports the sliding door plate on the upper rail and the vicinity of the interlocking plate in which a lateral force acts on the sliding door plate. For this reason, when a lateral force is applied to the traveling shaft via the interlocking plate, a large force acts on the traveling shaft at the lower part, which is a contact point with the interlocking plate, and the force is applied near the upper runner. It is difficult to communicate. For this reason, the traveling shaft upper part and the runner cannot follow the movement of the traveling shaft lower part, and the traveling shaft may be inclined. When the travel axis is inclined as described above, the force for moving the runner is hardly applied horizontally along the rail direction, which obstructs the smooth opening and closing of the sliding door plate, which is not preferable.

  Accordingly, the first object of the present invention is to interlock the sliding door plates with a simple structure, and the second problem is to enable the sliding door plate to be opened and closed smoothly.

  In order to solve the first problem, the present invention provides a moving element that moves in the same direction on each sliding door plate so that adjacent sliding door plates are linked to each other, and connects both moving members. It is. In this way, the slider of one sliding door plate moves in the same direction as the sliding door plate by moving the one sliding door plate, and the moving member of the other sliding door plate is the one moving member. Because they are connected to each other, they move together. When the other moving member moves, the corresponding other sliding door plate can be moved in the same direction as the one sliding door plate, and the structure is simple.

  The specific configuration is that each of the plurality of parallel rails is provided with a sliding door plate movably along the rail, and when the one sliding door plate is moved along the rail, the other sliding door plate that is adjacent as the movement moves. In the sliding door structure in which the first sliding door plate is moved along the rail, a movable member movable in the moving direction is provided on the one sliding door plate, and a movable member movable in the moving direction is also provided on the other sliding door plate. Provided, and both the movers are connected by a connecting rod. When the one sliding door plate is moved along the rail, the other sliding door is moved along the rail via both the moving elements and the connecting rods.

  In this way, it is not necessary to move a plurality of sliding door plates separately, and each sliding door plate always moves in conjunction with each other to reach a predetermined position, so that opening and closing is easy. In addition, by appropriately setting the length of the connecting rod and the connecting position between the connecting rod and the two sliders, the two adjacent sliding door plates can maintain a predetermined positional relationship. It is easy to align each sliding door plate at a predetermined position during the operation or the closing operation.

  Further, if the moving element is fitted to a rail along the moving direction to be movable, the moving element moves more smoothly. Further, a roller is provided on the moving element, and the moving element is fitted to the rail through the roller. This is preferable because the moving element moves more smoothly.

  In order to solve the second problem, in the present invention, the sliding door plate is supported by the rail via a pair of runners fitted to the rail, and the moving member of the sliding door plate is A configuration may be adopted in which the sliding door plate is disposed between the pair of runners and is fitted on the same rail as the pair of runners. In this way, since the runner and the mover run on the same rail, a force easily acts in the moving direction along the rail from the mover to the runner and from the runner to the mover. For this reason, a sliding door board comes to be able to open and close smoothly.

  Further, if the sliding door plate is supported by an upper rail, and the moving element is movable to the upper rail, the connecting rod is located above the sliding door plate, so that it does not stand out from the outside. It is preferable in appearance.

  Furthermore, if a cushioning member made of an elastic body is provided on any of the moving element and the contact surface of the runner that contacts the moving element, the impact when the moving element and the runner come into contact is weakened. It prevents the sliding door plates from bouncing in the lateral direction due to an impact, and makes it easy for them to move together.

  Since this invention was made as mentioned above, the structure of the sliding door board and the member which makes it interlock | cooperate is simple, and the interlocking sliding door board can be opened and closed smoothly.

  One embodiment is shown in FIGS. The sliding door structure of this embodiment is composed of three sliding door plates 1 that are slidably supported by three rails 5 provided in parallel at the top of the opening 3 in the front opening of the cabinet 2.

That is, the traveling shaft 7 and the hanging bracket 8 are integrated, and the hanging bracket 8 fits snugly into the dug portions 9 provided at both ends of the upper end of the sliding door plate 1 as shown in FIG. It is fixed with screws. Further, a fitting hole 8b having a lock mechanism is opened in the side surface of the hanging metal fitting 8, and a locking claw (not shown) provided on the cabinet 2 side is engaged to fix the sliding door plate 1. To get. Further, by turning the adjusting screw 8 c exposed on the side surface of the hanging bracket 8, the protruding height of the traveling shaft 7 from the hanging bracket 8 can be adjusted.

  As shown in FIG. 1, each pair of runners 6, 6 of the three sliding door plates 1 is placed so as to be able to run on the corresponding upper rail 5, and the running shaft 7 is a receiving portion 5 d of the rail 5. It can pass through the lower opening between 5d. The sliding door plate 1 is supported by being suspended via the runner 6.

  As shown in FIG. 2, guides 12, 13, and 14 for guiding the sliding door plate 1 so that the sliding door plate 1 does not swing in the depth direction of the cabinet 2, that is, in the direction perpendicular to the rail 5, are provided at the lower part of the sliding door plate 1. Yes. As for the configuration, for the sliding door plate 1 (hereinafter referred to as the front sliding door plate 1) located at the forefront of the cabinet 2, a groove 22 along the length direction of the rail 5 is provided on the lower surface of the sliding door plate 1. A guide 12 that protrudes upward from the lower surface of the front opening of the cabinet is fitted into the groove 22 so that both slide together with the sliding of the sliding door plate 1. Moreover, about the sliding door board 1 (henceforth the central sliding door board 1) located in the center, the groove | channel 23 along the length direction of the rail 5 is similarly provided in the lower surface of the sliding door board 1, and in this groove | channel 23, A guide 13 that extends from the lower end of the front sliding door plate 1 and the rear sliding door plate 1 (hereinafter referred to as the rear sliding door plate 1) and is inverted and protrudes upward is fitted. It is designed to slide and roll. Further, the rear sliding door plate 1 is provided with a roller 24 projecting downward on its lower surface, and this roller 24 fits into the groove-shaped guide 14 on the lower surface of the front opening of the cabinet. Both slide and roll together with the slide. With the above configuration, the three sliding door plates 1 can be guided along the rails 5 and can move smoothly.

  Next, a member for interlocking the three sliding door plates 1 will be described. The rear sliding door plate 1 is provided with a movable element 4 movable in the moving direction and disposed between the runners 6 and 6. At the same time, a roller 4d of the moving element 4 is placed in the recess 5d of the rail 5, so that the moving element 4 can travel on the roller 4d. The moving element 4 is not connected to the sliding door plate 1, and both can move separately on the rail 5 as long as the sliding door plate 1 and the moving element 4 do not contact each other. Yes.

  In addition, similarly to the rear sliding door plate 1, the central sliding door plate 1 is provided with a movable element 4 that is movable in the moving direction, and is disposed between the runners 6, 6. A roller 4d of the moving element 4 is placed on 5d, and the moving element 4 can travel on the roller 4d via the roller 4d.

  As shown in FIG. 3, the structure of the moving element 4 is such that two moving axles 4b in a direction perpendicular to the rail 5 are supported on the moving body 4a so as to be rotatable around the respective axes. The rollers 4d are attached to both ends of 4b and 4b.

  The moving element 4 of the rear sliding door plate 1 and the moving element 4 of the central sliding door plate 1 are connected by a connecting rod 10 shown in FIG. The connecting rod 10 has a main body portion 10a that is long in the direction along the rail 5, and connecting portions 10b and 10b that protrude in the direction perpendicular to the rail 5 are formed at both ends in the length direction of the main body portion 10a. Yes. The main body 10a is provided with a rib 10c shown in the drawing to improve its strength. The rib 10c is appropriately provided as necessary and can be omitted. The connecting parts 10b and 10b of the connecting rod 10 are respectively attached to the lower surfaces of the both moving body 4a and 4a via screws or the like, so that both moving elements 4 and 4 are connected. The connecting rod 10 does not hit the sliding door plate 1 or the runner 6 so that the moving element 4 does not impede the traveling when the moving element 4 travels on the rail 5, and as long as it functions as such. In this case, the shape of the connecting rod 10 is arbitrary, and a well-known method can be adopted as a method of connecting the connecting rod 10 and the moving element 4.

  In addition, buffer members 11 made of an elastic material such as a rubber material are attached to both ends of the moving body 4 in the moving direction. The buffer member 11 is attached at a position where it can contact the side surface of the runner body 6a of the runner 6 traveling on the same rail 5.

  The operation of this sliding door structure will be explained. First, as shown in FIG. 4, the predetermined overlapping portion w is maintained so that the three sliding door plates 1 are in a state of completely closing the front opening 3 of the cabinet 2. Is arranged. The rear sliding door plate 1 shown on the left side in the drawing is in contact with the left side wall of the opening 3, and on the right side of the runner 6 located on the side wall side, the runner on the side wall side runs on the same rail 5. 6 and a brake part 6 ′ integrated with 6. A front sliding door plate 1 is provided on the right side of the drawing with the central sliding door plate 1 shown in the center of the drawing in between, and the front sliding door plate 1 is in contact with the right side wall of the opening 3. . Since the front sliding door plate 1 is not provided with the moving element 4, the front sliding door plate 1 is not linked to the other sliding door plates 1.

  When opening the sliding door, if the handle 15 provided at the left end portion of the rear sliding door plate 1 shown in FIG. 4A is grasped, and the rear sliding door plate 1 is slid to the right as shown by the arrow in the figure. When the predetermined opening is reached, as shown in FIG. 4 (b), the brake portion 6 ′ integrated with the runner 6 comes into contact with the moving element 4 of the rear sliding door plate 1. When the sliding door plate 1 is further slid to the right side, the movable element 4 that is in contact with the rear sliding door plate 1 slides to the right side. At this time, since the moving element 4 of the rear sliding door plate 1 and the moving element 4 of the central sliding door plate 1 are connected by the connecting rod 10, both the moving elements 4 are moved as the rear sliding door plate 1 slides and moves. , 4 and the connecting rod 10 also move to the right side, and eventually the moving element 4 of the central sliding door plate 1 contacts the runner 6 on the right side of the central sliding door plate 1 as shown in FIG. Thereafter, when the sliding door plate 1 is further slid to the right side, the rear sliding door plate 1 and the central sliding door plate 1 move in conjunction with each other through the moving elements 4 and 4 and the connecting rod 10, and the sliding door plate 1 , 1 move along the corresponding rails 5 to reach the open state of the sliding door shown in FIG.

  Next, when closing the sliding door, the handle 15 provided at the left end of the rear sliding door plate 1 shown in FIG. 5A is gripped, and the rear sliding door plate 1 is slid to the left as indicated by the arrow in the figure. Let When the rear sliding door plate 1 reaches a predetermined opening, the right runner 6 of the rear sliding door plate 1 comes into contact with the moving element 4 of the rear sliding door plate 1 as shown in FIG. Further, when the rear sliding door plate 1 is slid to the left side, the movable element 4 that is in contact with the rear sliding door plate 1 slides to the left side. At this time, both the moving elements 4 and 4 and the connecting rod 10 also move to the left side, and eventually the moving element 4 of the central sliding door plate 1 becomes a runner on the left side of the central sliding door plate 1 as shown in FIG. 6 abuts. Thereafter, when the rear sliding door plate 1 is further slid to the left side, the rear sliding door plate 1 and the central sliding door plate 1 move in conjunction with each other through the moving elements 4 and 4 and the connecting rod 10, and both sliding door plates are moved. 1 and 1 move along the corresponding rails 5 respectively, and the sliding door shown in FIG. 5D is completely closed.

  In the process of opening and closing the sliding door plate 1, the force for interlocking the sliding door plate 1 acts on the same straight line along the rail 5 between the moving element 4 and the runner 6. The force which tries to act acts without waste along the rail 5, and the sliding door board 1 can slide smoothly. In addition, the front sliding door plate 1 shown on the right side in the figure does not move in the above series of operations, but in the storage space of the cabinet 2, when putting in and out the stored items located behind the front sliding door plate 1, If the grip part provided in the appropriate position of the front sliding door board 1 is grasped and it slides to the left side, the front sliding door board 1 can be opened and closed independently.

  In this embodiment, two axles 6b are provided for one runner 6. However, the present invention is not limited to this embodiment, and the number of axles 6b is arbitrary, which hinders the sliding and sliding of the sliding door plate 1. If not, for example, a runner 6 constituted by a single axle 6b may be employed. Similarly, the number of the axles 4b of the movable element 4 is arbitrary, and as shown in FIG. 6, it may be constituted by a single axle 4b.

  Moreover, in this embodiment, the rail 5 which supports the sliding door board 1 via the runner 6 was provided only in the upper part of the sliding door board 1, and the guide etc. which guide | induced the slide were provided in the lower part of the sliding door board 1. However, this guide and other aspects are free. Further, instead of the guide or the like, rails 5 are arranged on both upper and lower sides of the sliding door plate 1, and runners 6 are arranged on the upper and lower rails 5 to support the sliding door plate 1 on the upper and lower rails 5 and 5. Also good. At this time, the mover 4 may be provided on both the upper and lower sides of the sliding door plate 1 and may be provided so as to be movable on the upper and lower rails 5 and 5, respectively, or may be provided on either the upper or lower side of the sliding door plate 1.

  In addition, although the smooth movement and sliding of the moving element 4 are somewhat inferior, a structure in which the moving element 4 does not have the roller 4d is also conceivable. Further, the movable element 4 does not fit into the rail 5 that supports the sliding door plate 1 but fits into another independently provided rail, or the movable element 4 does not go through the rail and other known guidance mechanisms. A configuration in which the sliding door plate 1 is movable in the moving direction is also conceivable. For example, a pair of rails or a pair of guide mechanisms facing each other between the opposing side surfaces of the adjacent sliding door plates 1 and 1 are provided, and each of the moving elements 4 and 4 is respectively provided by the pair of rails or the pair of guide mechanisms. It is movable along the moving direction of the sliding door plate 1, and the connecting rod 10 is arranged so as not to interfere with the sliding door plate 1 in the space between the sliding door plates 1 and 1. Such as the configuration.

  In such a configuration, when the one sliding door plate 1 is moved along the rail 5, the other sliding door plate 1 is moved to the rail 5 via the moving elements 4, 4 and the connecting rod 10 as the movement is made. In order to move along the sliding door plates 1 and 1, when the sliding door plates 1 and 1 reach a predetermined degree of overlap, the moving element 4 does not contact the runner 6, but instead of the sliding door plates 1 and 1. While being in contact with any part, for example, the rail or a wall provided at the end of the guide mechanism, the sliding door plates 1 and 1 cause the sliders 4 and 4 and the connecting rod 10 to be brought into contact with each other. The same function can be achieved by moving in conjunction with each other.

  The number of the sliding door plates 1 used in this sliding door structure is not limited to three, and the number of the sliding door plates 1 to be used and the combination of the sliding door plates 1 linked to each other among the plurality of sliding door plates 1 are free. is there. For example, in a configuration having three or more sliding door plates 1, adjacent sliding door plates 1 and 1 are connected to each other via the moving element 4 and the connecting rod 10, and three or more sliding door plates 1 are adjacent to each other. It is also possible to adopt a configuration that is interlocked with the sliding door plate 1 to be operated. Conversely, in the sliding door structure configured to close the opening 3 with the two sliding door plates 1, 1, a so-called door pocket is provided on the side of the opening 3, and both the sliding door plates 1, 1 are connected together. A configuration in which the two sliding door plates 1 and 1 are interlocked with each other in the above configuration can be adopted while being able to be stored in the door pocket.

  Of course, this sliding door structure can also be used in other than the cabinet 2 shown in the embodiment, and can also be used in various storage devices such as closets having the same sliding door type opening / closing mechanism, or partition doors and window sashes. It is.
