Description

  The present invention relates to a reverse nesting type nesting rack capable of stacking and nesting frame structures.

  A nesting rack is used as a tool for transporting and storing industrial products and goods, etc., safely, reliably and inexpensively. The nesting rack has a structure that can be stacked up and down in use and stacked in a skeleton structure, and can be stored by nesting racks of the same structure inside when stored. In addition, the nesting rack has a normal type (normal nesting type) in which the upper part is opened and a shelf (base part) is provided in the lower part, and a reverse type in which the lower part is opened and a shelf (base part) is provided in the upper part. (Reverse nesting type).

  Since nesting racks are used by being stacked in a plurality of stages, it is necessary to prevent overturning due to vibration. Conventionally, as an anti-seismic mechanism for a nesting rack, a V-shaped receptacle is provided at the top of the rack, and a V-shaped fitting is provided at the bottom to fit the receptacle. The thing which ensures seismic resistance by fitting a receiving tool and the fitting part of the other rack is proposed (refer patent document 1). The nesting rack is an inverted nesting rack having a pair of left and right stoppers on the upper rear surface, and a pair of left and right protrusions protruding in the horizontal direction on the lower rear surface, and is detachable between the stopper bodies. The thing which has a convex part is proposed (refer patent document 2). Further, as a simpler method, a method of seismic reinforcement by fixing columns between racks with a dedicated metal fitting or band and connecting the racks is adopted.

  However, any of the conventional methods improves the earthquake resistance by connecting adjacent racks, and does not pay attention to the earthquake resistance of the rack alone. If the earthquake resistance of the rack alone is insufficient, sufficient earthquake resistance may not be obtained even when these racks are connected. In particular, with a normal nesting rack, the load of the load loaded on the lower shelf can greatly improve stability compared to when there is no load, but with a reverse nesting rack, the load to be stored there Since the load of an object is not applied to the rack itself, a significant improvement in stability cannot be expected even when there is a load (carrying object). In addition, when providing a complicated exclusive structure like patent document 1 or patent document 2, a manufacturing cost becomes high.

  The present invention has been made to address such problems, and an object thereof is to provide a reverse nesting rack that has a simple structure and is excellent in earthquake resistance.

  The nesting rack according to the present invention includes a ceiling portion having a substantially rectangular plane shape, struts erected at the four corners of the ceiling portion, and lower end portions of the struts adjacent to each other except for the front surface side for loading the load. A reverse nesting rack nesting rack comprising a U-shaped support portion composed of a connected horizontal frame, wherein the nesting rack is configured such that the load is the above-mentioned support surface for supporting the nesting rack. It is used by being placed on the U-shaped inner side portion of the support part, and the support part has a connecting member that is connected to at least one of the horizontal frames and placed on the support surface. The connecting member is fixed between the load and the support surface by the weight of the load.

  The connecting member is detachably connected to the horizontal frame, or is movably connected to the outside of the U-shaped internal range during nesting.

  The connecting member is an integral member connected to at least two of the horizontal frames. In particular, the connecting member is a long flat plate member connected to a pair of left and right horizontal frames constituting the U-shape.

  The support unit has a column support part at a position adjacent to the back surface of the support column on the front side, and supports the column of another nesting rack immediately above by the column support unit at the time of nesting.

  The nesting rack according to the present invention connects a ceiling part having a substantially rectangular plane shape, pillars erected at the four corners of the ceiling part, and lower ends of adjacent pillars excluding the front side for carrying a load. A U-shaped support portion made of a horizontal frame, and the load is placed on a portion of the support portion that supports the nesting rack on the inner side of the U-shape of the support portion. The support portion includes a connecting member connected to at least one of the horizontal frames and placed on the support surface, and the connecting member is disposed between the load and the support surface. Since it is fixed by the weight of the object, the entire rack is fixed by the weight of the load via the connecting member, although the structure is simple, and the rack alone has excellent earthquake resistance. As a result, when stacked, the entire structure composed of a plurality of racks is excellent in earthquake resistance.

  In addition, since the connecting member is detachably connected to the horizontal frame, or is movably connected outside the U-shaped inner range during nesting, the connecting member is supported during use. Even in the case where it is provided at the center of the U-shaped portion, nesting can be performed by removing it at the time of nesting or by moving it to the outside.

  Moreover, since it is an integral member connected to at least two of the horizontal frames, it is excellent in earthquake resistance. In particular, since the connecting member is a long flat plate member that connects the pair of left and right horizontal frames constituting the U-shape, it has a very simple structure, can be manufactured at low cost, is not easily damaged, and is stored. And management is easy.

  In addition, the support unit has a support unit at a position adjacent to the back of the front support column, and at the time of nesting, the support unit supports the support column of the other nesting rack immediately above. Excellent in earthquake resistance during transportation.

More specifically, the ceiling part 2 having a substantially rectangular plane shape, the pillars 3a to 3d erected at the four corners of the ceiling part 2, and the lower ends of the neighboring pillars excluding the front side for carrying the load 5 And a U-shaped support portion 4 composed of horizontal frames 4a to 4c connecting the portions. The nesting rack 1 is a reverse nesting rack in which a lower portion is opened and a shelf (ceiling portion 2) is provided on the upper portion. The load 5 is placed on a portion of the support surface 6 that supports the nesting rack 1 inside the U-shape of the support portion 4 via a pallet or the like as necessary.

  The material of the nesting rack 1 is not particularly limited, and metal materials such as steel (including those subjected to rust prevention such as coating and plating), stainless steel, other alloys, and synthetic resin materials having excellent mechanical strength are used. Can be adopted. Further, the material may be different for each part. Resin nesting racks are lighter than metal ones, so they are susceptible to vibration, but by providing a connecting member described later, sufficient quake resistance even with resin nesting racks Can be secured.

  The nesting rack 1 according to the present invention is characterized in that the support member 4 has a connecting member 7. The connecting member 7 is connected to the horizontal frames 4 a and 4 c (connects the horizontal frames 4 a and 4 c) and is placed on the support surface 6. The connection member 7 is fixed by the weight of the load 5 between the load 5 (including a shelf such as a pallet and the like) and the support surface 6 after the load is loaded. As a result, the entire rack is fixed by the weight of the load 5 via the connecting member 7, and the nesting rack 1 alone is excellent in earthquake resistance. In the present invention, the “support portion” is a U-shaped portion composed of three horizontal frames as described above, and the connecting member is “connected to at least one of the horizontal frames” It includes the case where it is connected to the connecting portion (support portion) of the horizontal frame.

Both end portions 7a and 7b of the connecting member 7 have a U-shaped cross section that can be fitted to each horizontal frame from above, and are detachably fitted to the horizontal frame. The connecting member 7 is placed on the support surface 6 and is fixed between the support surface 6 and the load 5 and does not support the entire weight of the load 5 itself. By adopting a bar shape as shown in FIG. 1, the support surface and the load can be securely sandwiched and can be stably fixed by suppressing the rack support from above without interfering with it. Become. Moreover, it has a simple structure, can be manufactured at low cost, is not easily damaged, and is easy to store and manage.

  The connecting member 7 is not limited to the shape shown in FIG. 1 as long as the connecting member 7 has a structure capable of fixing the grazing of the support portion 4 of the rack using the weight of the load 5. For example, a long flat plate member connected to the horizontal frames 4a and 4b, a long flat plate member connected to the horizontal frames 4c and 4b, and the like may be used. In this case, both ends of the connecting member 7 can have the same shape as in FIG. Further, the connecting member 7 may be a semi-long plate member that does not connect the horizontal frames. In this case, the connection member is provided on each of the two or more horizontal frames, and the plurality of connection members are fixed between the load 5 and the support surface 6 respectively, thereby providing sufficient earthquake resistance. Can be secured. Moreover, in each of the above embodiments, the shape of the connecting member can be not only a flat plate shape but also a fine columnar shape, a narrow prismatic shape, or the like.

  As the material of the connecting member 7, the same metal material or synthetic resin material as that of the rack body can be adopted. The material of the rack body is not necessarily the same, and the rack body may be made of a steel material, and the connecting member may be made of a resin material in consideration of the detaching operation and handling at the time of storage.

  Further, the connecting member can have any structure that does not hinder the nesting, for example, a detachable shape shown in FIG. 1 or a shape that can be moved outward from the U-shaped central portion of the support portion. In addition, the connection member is in a position where it is fixed between the load and the support surface during use, and at a position where it does not interfere with other racks during nesting (part of the end, etc.). In this case, it is not necessary to be detachable.

  The nesting rack 1 shown in FIG. 1 is a rack whose connection type is a pin type. FIG. 2 shows a state when the nesting racks are stacked.
