[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a shelf apparatus in which a plurality of shelves are stacked and can be transported after being disassembled.
[0002]
[Prior art]
  This conventional seed shelf device is shown, for example, in Japanese Patent Application No. 2000-001497 (B65D19 / 08) filed earlier by the present applicant. This shelf apparatus is composed of a base and side walls provided upright around the bottom wall of the base. Engaging portions are provided in the vicinity of the four corners of the base, and this engaging portion is configured to be engageable with the upper end of the side wall, and is located on the inner side in the vicinity of the front and rear side walls and downwards near the four corners of the base. It protrudes while expanding.
[0003]
  In addition, the base was provided with an L-shaped metal frame whose upper surface was raised, and a bottom wall made of a single plate-like metal panel was fixed by welding over the entire inner surface of the frame. The rising part around the base is a vertical wall. Side walls are set up inside the vertical wall, and the vertical wall, the lower part of the side wall, and each adjacent side wall are fixed with bolts, and placed in a polyethylene bag or a plastic bag. After fresh foods such as seafood, fruits and vegetables were directly stored in the shelf device, the shelf device was stored in a container and transported.
[0004]
  Then, after transporting the fresh food, the shelf device was disassembled by removing the bolts that were fixed, and returned with the bolts that had been removed from the side wall on the base. The side wall is formed by welding and fixing a plurality of hat-shaped reinforcing members and a plurality of Z-shaped reinforcing members to the metal panel substantially in parallel, and in a direction orthogonal to a substantially central portion of the reinforcing members and the hat-shaped reinforcing member. A Z-shaped reinforcing member was fixed by welding.
[0005]
[Problems to be solved by the invention]
  However, the engaging part that protrudes while expanding downward near the four corners of the base extends below the base by a predetermined distance because the forklift claw is inserted under the base and the shelf device is loaded on the container. It was expanded after I let it. In this case, since the engaging part formed an engaging part that welded a plurality of metal plates and extended downward from the base and expanded, it took a great deal of time to cut and weld each metal plate. There was a problem that took.
[0006]
  In addition, the side wall welds and fixes the plurality of Z-shaped reinforcing members and the plurality of hat-shaped reinforcing members to the metal panel substantially in parallel, and is orthogonal to the substantially central portion of the Z-shaped reinforcing member and the hat-shaped reinforcing member. The Z-shaped reinforcing member is welded and fixed in the direction to be bent, but the Z-shaped reinforcing member is not box-shaped and is easily bent. For this reason, when fresh food items are stored in the shelf device, there is a problem that the side walls are deformed and bulge due to the weight of the fresh food items.
[0007]
  In addition, after transporting fresh food, many shelves were disassembled by removing bolts, and then stacked with side walls on the base and stored in containers. In addition, the bolts obtained by disassembling a large number of shelf devices are collectively put in a predetermined container and returned together with the container storing the disassembled shelf devices. This bolt is there is a problem that you lose the really bolt because it is returned in a container is removed from the shelf device. For this reason, there was also a problem that the shelf device could not be assembled due to insufficient bolts.
[0008]
  In addition, the base was welded and fixed to the bottom wall made of a single plate-like metal panel over the entire inner surface of the L-shaped metal frame, but the L-shaped metal frame was welded to the bottom wall. There was a step in the part, and this step was located inside the side wall. For this reason, there has been a problem that polyethylene bags or plastic bags containing fresh food such as seafood, fruits or vegetables stored in a shelf device are cut by friction with a step due to vibration of transportation.
[0009]
  The present invention has been made to solve the problems of the related art, and an object of the present invention is to provide a shelf apparatus that can be disassembled and assembled with a simple structure and that is difficult to deform side walls. .
[0010]
[Means for Solving the Problems]
  That is, the shelf apparatus of the present invention includes a base and a plurality of side walls standing around the base,The base and the side wall and each adjacent side wall are detachably joined to each other at the joint, and each joint is one of the base and the side wall to be joined to each other or each adjacent side wall.
