Description

  TECHNICAL FIELD The present invention relates to a shelf mounting structure in an assembly shelf, and more particularly to a shelf mounting structure that can be formed into a rigid assembly shelf by being firmly coupled to both side plates standing at regular intervals. It is.

  Conventionally, in assembly-type storage shelves, book shelves, etc., side plates are erected with a certain distance in the left-right direction, and top plates and bottom plates are bolted between the upper and lower ends of these side plates, respectively. Assembling a rectangular frame-shaped shelf body integrally with each other, arranging a shelf plate between the side plates on both the left and right sides of the shelf body, and projecting both end portions of the shelf plate to the opposing surface of the side plate It is generally known that it is configured to be received on several shafts, but in such a shelf mounting structure, an upward force by a hand or the like has unexpectedly acted on the lower surface of the shelf. In this case, there is a problem in that the shelf plate is lifted from the shaft body, and the article placed on the shelf plate is dropped to cause damage or the like.

For this reason, for example, as described in Patent Document 1 and Patent Document 2, an assembly shelf that can prevent the shelf from floating from the shaft body has been developed. The shelf mounting structure in the assembly shelf is formed by engraving a guide groove having a constant depth from the end of the end of the shelf toward the inside at the front and rear ends of the both ends of the shelf and in the front and rear direction. A shaft body engaging groove is formed by forming the rear end portion of the groove portion in an insertion groove portion opened from the lower surface of the shelf plate, and the shelf plate is inserted between both side plates so that the same height on the opposing surface of these both side plates is provided. The insertion groove portions of the engagement grooves provided on the front and rear portions of the both ends of the end face are opposed to the shaft body projecting at the front and rear portions of the position, and the shelf plate is lowered from this state to disengage the front and rear shaft bodies. Each of the side plates is inserted into the insertion groove portion of the mating groove and brought into contact with the upper wall surface of the rear end portion of the guide groove portion.After that, the shelf plate is pushed toward the back of the shelf, so that the side plate is made into the shaft body via the guide groove portion. The structure is supported so that it cannot be lifted.
