Description

  The present invention relates to a multistage slide rail including two or more rails, and a storage provided with such a multistage slide rail.

  2. Description of the Related Art Conventionally, as a kind of storage installed above a kitchen, a so-called lifting shelf in which a hanging shelf body moves up and down is provided. There are two types of lifting shelves: manual type and electric type. As a manual type, for example, Patent Literature 1 proposes an elevating shelf including a hanging shelf body that moves up and down in a straight line.

Japanese Patent No. 4801454

  In the lifting shelf, the hanging shelf body is housed in a cabinet installed on the wall surface when not in use, and is pulled out of the cabinet when in use. At this time, a multi-stage slide rail may be arranged on the inner surface of the cabinet as guide means for raising and lowering the hanging shelf main body in a vertical straight line. The multi-stage slide rail is configured to include two or more rails, and each of the rails slides relative to each other, so that the hanging shelf attached to the other rail with respect to the cabinet to which one rail is attached. The main body can be moved.

  Here, in the multi-stage slide rail, a stopper is formed by projecting the outer surface of the inner rail and the inner surface of the outer rail. Is prevented from falling off the outer rail. However, with such a configuration, when the suspension rack body is pulled downward (when the slide rail is slid), a contact sound is generated between the stoppers. There was a risk of becoming.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a multistage slide rail and a storage that can reduce the contact sound generated when the multistage slide rail is slid and can enhance the user's comfort. It is said.

  In order to solve the above problems, a typical configuration of a multi-stage slide rail according to the present invention is a multi-stage slide rail including two or more rails, and is arranged inside the first rail and the first rail. The second rail, the spacer arranged in the gap between the first rail and the second rail, the bearing held by the spacer, and one of the spacers when protruding from the inner surface of the first rail and pulling out the second rail A first protrusion that contacts the end of the second rail, a second protrusion that protrudes from the outer surface of the second rail and contacts the other end of the spacer when the second rail is pulled out, and a diameter equal to or less than the bearing. And a resin ball disposed between the spacer and the first protrusion or between the spacer and the second protrusion.

  According to the above configuration, when the multistage slide rail is slid, the other moves relative to one of the first rail and the second rail. A spacer is disposed between the first rail and the second rail. When the spacer is locked to the first protrusion and the second protrusion, the amount of movement of the second rail is restricted, and The falling off of the two rails is prevented. At this time, in the above configuration, the resin balls are arranged between the spacer and the first protrusion or between the spacer and the second protrusion. As a result, direct contact between the spacer and the first protrusion or the second protrusion is prevented, and the resin ball acts as a cushioning material, and the contact noise is greatly reduced. Therefore, it is possible to improve the comfort of the user.

  In order to solve the above problems, a typical configuration of a storage according to the present invention includes a multi-stage slide rail as described above, a box-shaped cabinet whose back surface is fixedly installed on a wall surface and at least opened downward, and a cabinet. A multi-stage slide rail attached to the side wall of the cabinet so that the longitudinal direction is the vertical direction, and the cabinet and the shelf main body are multi-stage slide rails. It is connected so that raising / lowering is possible.

  The component corresponding to the technical idea in the multistage slide rail mentioned above and its description are applicable also to the said storage. In particular, in a storage in which the hanging shelf body moves up and down, the hanging shelf body moves downward due to its own weight or the weight of the stored item, so that the contact sound when the rail comes into contact tends to increase. For this reason, it becomes possible to acquire a more remarkable effect by using the multistage rail mentioned above for the storage in which a hanging shelf main body goes up and down.

  The multi-stage slide rail is a three-stage slide rail further provided with a third rail disposed inside the second rail, wherein the first rail is fixed to the cabinet and the third rail is fixed to the hanging shelf body. Good. When the vertical movement range of the hanging rack body is determined by the lifting mechanism, if the slide rail has two stages, if the vertical movement range is within the stroke range of the slide rail, the protrusion of the slide rail will collide with the spacer. Can be prevented. However, in a multi-stage slide rail configured to include three or more rails, the stroke of one stage or more is naturally expanded and contracted, so the center rail in the second stage inevitably collides with the spacer. Even in such a case, if the present invention is applied, it is possible to greatly reduce the contact sound, and thus it is possible to enhance the comfort of the user.

  ADVANTAGE OF THE INVENTION According to this invention, the multistage slide rail and storage which can reduce the contact sound produced when sliding a multistage slide rail and can improve a user's comfort can be provided.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 is an overall perspective view of a storage 100 according to the present embodiment. In the following description, the multistage slide rail 400 of the present embodiment provided in the storage 100 will be described together with the storage 100 shown in FIG. 1 in detail. In addition, in this embodiment, although the raising / lowering shelf which is installed above the kitchen and the raising / lowering shelf main body 200 raises / lowers is illustrated as the storage 100, it is not limited to this. The present invention can also be applied to, for example, a storage in which a drawer slides in the front-rear direction by a multistage slide rail and the multistage slide rail.

  As shown in FIG. 1, in the storage 100 of the present embodiment, the back surface of a box-shaped cabinet 110 that is open at the bottom is fixedly installed on a wall surface (not shown), and is vertically linear with respect to the cabinet 110. A hanging shelf main body 200 that moves up and down is attached. The cabinet 110 is also open at the front, and a front door is installed there. However, in order to facilitate understanding, the front door is not shown in the present embodiment.

  The hanging shelf main body 200 constitutes a storage space by the side plates 210 and 212 arranged on the left and right sides, and the upper plate 214 and the bottom plate 216 connecting them. A multistage slide rail 400 described later is connected to the rear of the left and right side plates 210 and 212. By this multistage slide rail 400, the hanging shelf body 200 is connected to the cabinet 110 so as to be movable up and down.

  2 is a detailed view of the storage 100 shown in FIG. 1, FIG. 2 (a) shows the hanging shelf body 200 of FIG. 1, and FIG. 2 (b) shows the link mechanism 300 of the cabinet 110. . FIG. 3 is a diagram for explaining the operation when the hanging shelf body 200 is raised and lowered. In order to facilitate understanding, in FIGS. 2 and 3, the cover 220 a (see FIG. 1) fitted to the outside of the connecting member 230 is not shown. Moreover, since the storage 100 is a left-right symmetric structure, in the following description, the structure of the right side of the storage 100 is mainly illustrated.

  As shown in FIG. 2A, swing columns 222a and 222b are attached to the left and right side plates 210 and 212 of the hanging shelf body 200 so as to be slidable in the front-rear direction. A connecting member 230 that connects the handle arm 220 extending in the width direction of the suspension rack body 200 and the swing columns 222a and 222b is attached to the lower part of the swing columns 222a and 222b. A handle arm 220 is attached to the lower end of the connecting member 230. When the user grips the handle arm 220 and operates it in the front-rear direction, the swinging pillars 222a and 222b move in the front-rear direction in conjunction with the handle arm 220. To do. The hanging shelf body 200 does not move in the front-rear direction.

  On the other hand, as shown in FIG. 1, a link mechanism 300 is attached to the inner surface of the side wall of the cabinet 110 (the right side is not shown in FIG. 1). As shown in FIG. 2B, the link mechanism 300 of this embodiment includes a first arm 312, a second arm 314, a third arm 316, and a fourth arm 318.

  The first arm 312 is an arm member that can swing up and down along an arcuate trajectory in which the tip bulges forward, and has one end connected to the upper end of the swing column 222a. On the other hand, the other end of the first arm 312 is connected to the base plate 302 and supported by the side wall of the cabinet 110 via the other end. The second arm 314 is a parallel arm that moves in parallel with the first arm 312, and one end is connected to the swing column 222 a and the other end is connected to the base plate 302 in the same manner as the first arm 312. That is, a parallelogram truss structure is formed by the base plate 302, the swing column 222 a, the first arm 312, and the second arm 314.

  The third arm 316 has one end connected to the first arm 312 and the other end connected to the fourth arm 318. The fourth arm 318 has one end connected to the third arm 316 and the other end connected to a spiral spring 320 accommodated in the base plate 302. As a result, the first arm 312 is connected to the spiral spring 320 via the third arm 316 and the fourth arm 318. The third arm 316 is connected to the outside of the axis of the first arm 312 and is pulled to rotate the first arm 312 upward. Therefore, the load on the hanging shelf body 200 and the stored items can be reduced, and the operation when the user houses the hanging shelf body 200 can be assisted.

  FIG. 3A illustrates a state in which the hanging shelf main body 200 is accommodated in the cabinet 110. As shown in FIG. 3A, in the state where the hanging shelf main body 200 is accommodated in the cabinet 110, the first arm 312 and the second arm 314 are in a position rotated upward. The first arm 312 is restricted from rotating forward by the urging force of the spiral spring 320 connected via the third arm 316 and the fourth arm 318.

  When the user grasps the handle arm 220 and pulls it forward from the state shown in FIG. 3A, the swing is connected to the handle arm 220 via the connecting member 230 as shown in FIG. The pillar 222a moves forward. Thereby, the 1st arm 312 and the 2nd arm 314 rotate toward the front, and the hanging shelf main body 200 descends.

  When the handle arm 220 is further pulled forward from the state shown in FIG. 3B, the first arm 312 and the second arm 314 further rotate forward. When the first arm 312 passes the horizontal position, the handle arm 220 moves rearward as shown in FIG. Then, as shown in FIG. 3 (d), the first arm 312 and the second arm 314 are rotated rearward so that the swing column 222 a and the hanging rack body 200 are further lowered, and the hanging rack body 200 is moved outside the cabinet 110. It will be pulled out.

  As described above, in the storage 100 of the present embodiment, the swing column 222a slides in the front-rear direction by gripping the handle arm 220 and sliding it in the front-rear direction. As the swing column 222a moves in the front-rear direction, the arm members (the first arm 312 and the second arm 314) rotate while drawing an arcuate locus, and the suspension rack body 200 moves up and down in conjunction with the movement. To do. In this manner, the suspension rack body 200 can be lifted and lowered by the sliding movement of the handle arm 220 and thus the swing column 222a. For this reason, the storage thing accommodated in the hanging shelf main body 200 can be taken out easily, and it becomes possible to improve a user's convenience.

  4 and 5 are diagrams for explaining the multistage slide rail 400 of the present embodiment. FIG. 4A is a plan view of the multistage slide rail 400 and shows a state where the multistage slide rail 400 is not slid. 4B is an exploded view of the multistage slide rail 400, and FIG. 4C is a cross-sectional view taken along the line AA in FIG. 4A. FIG. 5A is a plan view of the multistage slide rail 400 exemplifying a state in which the multistage slide rail 400 is slid. FIG.5 (b) is an enlarged view in the broken line of Fig.5 (a).

  As shown in FIG. 1, the storage 100 of the present embodiment includes a multi-stage slide rail 400 that connects the cabinet 110 and the hanging shelf body 200 so as to be movable up and down. The multistage slide rail 400 is attached to the side wall of the cabinet 110 such that the longitudinal direction is the vertical direction.

  As shown in FIG. 4A and FIG. 4C, the multi-stage slide rail 400 of this embodiment includes a first rail 410 (outer member), a second rail 420 (center member), and a third rail 430 (inner member). It is a three-stage slide rail configured to include three rails made up of members. In this embodiment, a three-stage rail including three rails is exemplified as the multi-stage slide rail 400. However, the present invention is not limited to this, and the present invention is applied to all multi-stage slide rails including two or more rails. It is possible.

  The first rail 410 is the outermost rail, and the second rail 420 is disposed inside the first rail 410. A third rail 430 is further disposed inside the second rail 420. In the present embodiment, the first rail 410 is fixed to the cabinet 110, the third rail 430 is fixed to the hanging shelf main body 200, and the first rail 410 and the third rail 430 are connected by the second rail 420.

  In this embodiment, an outer member is illustrated as the first rail 410, a center member is illustrated as the second rail 420, and an inner member is illustrated as the third rail 430. However, the present invention is not limited to this. For example, in the case of a two-stage slide rail, the outer member may be the first rail 410 and the inner member may be the second rail 420.

  As shown in FIGS. 4A and 4C, a spacer 440 is disposed in the gap between the first rail 410 and the second rail 420, and a bearing 450 is held by the spacer 440. A retainer 460 is disposed in the gap between the second rail 420 and the third rail 430, and a bearing 470 is also held by the retainer 460. The spacer 440 is made of resin and has a function of suppressing shaking (rattle) when the multistage slide rail 400 operates.

As shown in FIG. 4B, in the vicinity of the lower end of the first rail 410, it protrudes from the inner surface to the spacer 440 side (toward the second rail 420), and when the second rail 420 is pulled out, the spacer 440 A first projecting portion 412 that abuts one end portion or a resin ball 480 described later is formed. Near the upper end of the second rail 420, it protrudes from the outer surface toward the spacer 440 (toward the first rail 410) and hits the other end of the spacer 440 or the resin ball 480 when the second rail 420 is pulled out. The 2nd protrusion part 422 which touches is formed.

  As a feature of the multistage slide rail 400 of the present embodiment, a resin ball 480 having a diameter equal to or less than the bearing 450 is disposed between the spacer 440 and the second protrusion 422 as shown in FIG. ing. In principle, the diameter of the resin ball 480 is preferably the same as that of the bearing 450, but may be slightly smaller. However, it is necessary to have a size that does not drop off from the ball travel surface between the first rail 410 and the second rail 420.

  As shown in FIG. 3A, in the state in which the hanging shelf main body 200 is accommodated in the cabinet 110, in the multistage slide rail 400, the second rail 420 and the third rail 430 are the first rails as shown in FIG. 1 rail 410 is housed inside. When the user pulls the handle arm 220 forward, as shown in FIG. 3B, the first arm 312 and the second arm 314 rotate forward, and the hanging rack body 200 is lowered. Thus, the second rail 420 and the third rail 430 slide down from the inside of the first rail 410.

  When the handle arm 220 is further pulled forward, the first arm 312 and the second arm 314 are further rotated forward as shown in FIG. Thereby, the hanging shelf main body 200 moves further downward, and accordingly, the second rail 420 and the third rail 430 slide further downward. When the first arm 312 passes through the horizontal position, the handle arm 220 moves rearward. Then, as shown in FIG. 3D, the first arm 312 and the second arm 314 are rotated rearward, and the suspension rack body 200 is pulled out of the cabinet 110. At this time, the 2nd rail 420 and the 3rd rail 430 are pulled out to a minimum, and will be in the state shown in Drawing 5 (a).

  When the second rail 420 is pulled out as shown in FIG. 5A, the lower end (one end portion) of the spacer 440 contacts the first protrusion 412 as shown in FIG. The downward movement of 440 is restricted. At the upper end (the other end) of the spacer 440, if there is no resin ball 480, the upper end of the spacer 440 contacts the second protruding portion 422 of the second rail 420 and the upward movement is restricted. That is, the first protrusion 412 of the first rail 410 and the second protrusion 422 of the second rail 420 are in contact with each other via the spacer 440. As a result, the amount of movement of the second rail 420 is restricted, and the second rail 420 is prevented from falling off.

  At this time, in the multistage slide rail 400 of the present embodiment, the resin ball 480 is disposed between the spacer 440 and the second protrusion 422 as described above. For this reason, the spacer 440 and the 2nd protrusion part 422 will contact | abut via the resin ball | bowl 480, as shown in FIG.5 (b). Thereby, the contact sound can be reduced by the resin ball 480 formed by the contact between the spacer 440 and the second projecting portion 422 serving as a buffer material. Therefore, the comfort when using the storage 100 is improved.

  In particular, as in the case of the storage 100 illustrated in the present embodiment, when the hanging shelf main body 200 moves up and down in the vertical direction, the hanging shelf main body 200 moves downward due to its own weight or the weight of the stored item. The contact sound (collision sound) when the rail and the spacer contact each other tends to increase. Therefore, by applying the present invention to the multi-stage rail that moves the storage space such as the hanging shelf main body 200 in the vertical direction with respect to the cabinet 110, the effect of reducing the contact sound can be obtained more remarkably.

  The reason why the impact is alleviated by inserting the resin ball 480 is to absorb energy by elastic deformation of the sphere. Here, it is also possible to arrange a block made of an elastic material such as rubber as the buffer material. However, if it is a block, if it deforms and comes into contact with the rail, it may become a resistance when the rail travels. However, since the resin ball 480 rolls between the first rail 410 and the second rail 420 in the same manner as the bearing 450, there is no possibility of becoming a resistance. In addition, since the block is repeatedly subjected to a load at the same position, there is a possibility that the deformation remains and the shape changes. However, since the position (direction) where the load is applied constantly changes because the resin ball 480 rolls, deformation hardly remains and performance can be exhibited over a long period of time.

  FIG. 6 is a diagram for explaining another arrangement of the resin spheres 480, and illustrates a state in which a region corresponding to the broken line in FIG. 5A is enlarged. In the example illustrated in FIG. 5B, the configuration in which the resin ball 480 is disposed on the upper side of the spacer 440 (between the spacer 440 and the second projecting portion 422) is illustrated, but the configuration is not limited thereto. As shown in FIG. 6, the resin ball 480 may be disposed below the spacer 440 (between the spacer 440 and the first protrusion 412). According to this configuration, it is possible to reduce the contact noise when the spacer 440 contacts the first protrusion 412 and obtain the same effect as described above.

  The resin balls 480 may be arranged at two or more locations. For example, the resin balls 480 are arranged in both spaces between the spacer 440 and the first protrusion 412 and between the spacer 440 and the second protrusion 422. It is good also as composition to do. Furthermore, the number of resin balls 480 disposed between the first protrusion 412 or the second protrusion 422 and the spacer 440 is not limited, and two or more resin balls 480 are disposed in one space. It is good.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
