Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a product display shelf or a product display fixture without a shelf, or a rectangular frame-like frame structure in a partition or the like (hereinafter referred to as a display shelf or the like), in particular, upper and lower ends of a pair of left and right columns. The present invention relates to a frame structure such as a display shelf formed by connecting each other with horizontal connecting rods facing in the left-right direction.
[0002]
[Prior art]
In this type of conventional display shelf etc., a back plate is provided between the left and right support columns and the upper and lower horizontal connecting rods, and this back plate functions in the same way as a brace, etc. Even if the horizontal connection rod is not firmly connected, it is possible to prevent the column from rolling.
[0003]
[Problems to be solved by the invention]
However, in recent years, in order to enable so-called face-to-face sales, or to have a wide view inside the store, or to allow large items to be placed across the shelves before and after the column, the back plate has been removed, There is a demand for a so-called open type.
[0004]
However, if the back plate is removed from the conventional structure, the strength against the rolling of the column cannot be maintained sufficiently. Moreover, there is a possibility that the support pillars wobble and a gap is generated in the connecting portion.
