Description

  The present invention relates to a plate-to-plate connection structure and an assembly-type shelf device using the same, and more specifically, a plate space is connected vertically and horizontally to provide a storage space capable of storing articles and displaying products vertically and horizontally. The present invention relates to an assembly-type shelf device.

  Conventionally, in wooden furniture, the connection between a plate material and a plate material has been performed by using a wooden dowel or the like by using an adhesive or by using a fixing bracket. However, in the case of an adhesive structure using wooden dowels, disassembly is not possible. On the other hand, when a fixing bracket is used, there is a problem that the bracket is exposed on the surface to be used or the usability is very poor.

  In order to solve such a problem, various types of storage shelves and display shelves that are assembled by connecting plate members and pipes vertically and horizontally with connecting members and having a rectangular storage space in front view are provided. Here, as the types of plate materials, there are wood-based boards, synthetic resin boards, metal mesh boards, and the like. Examples of the wooden board include solid wood, flash board, and medium fiberboard.

  In Patent Document 1, there is an assembly shelf having a structure in which a plurality of plate members are fitted to the left and right and up and down via an intersection member, and the plate members are prevented from coming off and connected by connecting members fitted to both ends of the intersection member. It is disclosed. More specifically, a plurality of plate members having insertion protrusions or insertion portions at both ends, an insertion portion into which the insertion protrusions of these plate materials are inserted, or an insertion protrusion to be inserted into the insertion portion of the plate material An assembly shelf comprising a plurality of intersection members having a plurality of connecting members for fixing the plurality of plate members via these intersection members, and each locking projection formed on each of the connecting members is There is disclosed an assembly shelf characterized in that the engagement between each intersection member and each plate member is held when locked to each locking portion formed on the plate member.

  However, in the assembly shelf described in Patent Document 1, it is necessary that the end portion of the plate member is fitted to the side surface in the longitudinal direction of the intersection member from the side, and the connecting member is fitted to the front and rear end portions of the intersection member from the front and rear direction. In particular, when the plate material and the intersection member are fitted, the insertion protrusion is inserted into the insertion part with left and right or up and down displacement, so that an excessive force is applied to the fitting part during assembly or disassembly, resulting in damage. Careful assembly and disassembly work is required.

  If the plate material is a molded product made of synthetic resin, the manufacturing cost will not be very high even if the end fitting structure is somewhat complicated. However, in the case of a wood-based plate material, if the number of processing steps at the end increases, the cost will increase significantly. Since it becomes high, it is necessary to make it as simple as possible. In that case, the fixing bracket such as the angle bracket and the wood screw are exposed, and above all, it takes time to assemble and disassemble. There is.
