BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly structure for a product display wagon used in shops, supermarkets, department stores and the like.

[0002]

2. Description of the Related Art Conventionally, in a product display wagon W0 of this type, as shown in FIGS.
The lower surface rim is placed on the angle member 3 welded to the inner surface of the four horizontal frames 2, and each horizontal frame 2 is connected to the vertical frame 4 vertically arranged at each corner portion of the shelf board 1. Was configured.

The vertical frame 4 is composed of two vertical frame columns 5 and 6 to which the horizontal frame 2 is fixed by welding or the like. The columns 5 and 6 are connected to each other by one column. 5 is formed with a screw insertion hole 5a, and the other pillar 6 is formed with a screw threaded portion 6a in which a nut or the like is embedded.
After that, the screw 7 is screwed into the screw screwing portion 6a to connect the columns 5 and 6 to form the vertical frame 4.

[0004]

However, in the conventional assembling structure, since the vertical frame 4 connects the columns 5 and 6 in the shape of square poles so as to overlap each other, it is bulky and unsightly. I was letting it.

Further, when displaying a heavy product on the shelf board 1, the side surfaces of the columns 5 and 6 are simply brought into contact with each other, and a space is left between the columns 5 and 6. It was easy and there was room for improvement in terms of strength.

It is conceivable that the vertical frame is composed entirely of one quadrangular column support, and the horizontal frames are fixed to the two side faces of the support. In this case, since the product display wagon is normally assembled at a site such as a supermarket, a fixing means such as welding cannot be used, and a horizontal frame is fixed to a vertical frame by using a screw. However, even when the horizontal frame is connected to the vertical frame by using screws in this way, similarly, the horizontal frame end face is brought into contact with the vertical frame side surface, or the side surface of the horizontal frame and the vertical frame is similarly connected. Since they are brought into contact with each other and screwed together and they are connected by simply contacting each other with a small area one by one, the combined state of the vertical frame and the horizontal frame becomes very weak in strength, Not practical.

The present invention solves the above-mentioned problems, and an object thereof is to provide an assembly structure for a product display wagon in which the appearance of the vertical frame can be improved and the strength of the vertical frame can be improved. To do.

[0008]

The product display wagon according to the present invention is an assembly structure for a product display wagon in which two horizontal frames for supporting a shelf are connected to one vertical frame. The vertical frame is composed of a rectangular column-shaped vertical frame main body and an angle member having two side walls capable of contacting two of the four side surfaces of the vertical frame main body. One of the four non-contact surfaces with the angle member on the four side surfaces,
The horizontal frame is fixed to one side wall of the angle member, and a screw insertion hole is formed in a side wall of the angle member that is not fixed to the horizontal frame,
A screw threaded portion is formed at a position corresponding to the screw insertion hole in the vertical frame body, the angle member is brought into contact with the vertical frame body, and a screw is attached to the screw threaded portion through the screw insertion hole. It is characterized in that the vertical frame is formed by screwing.

[0009]

[Operation and effect of the invention] In the product display wagon according to the present invention, the vertical frame is composed of the vertical frame body and the angle member to which the horizontal frames are fixed, and the vertical frame body and the angle member are connected to each other. The two side walls of the angle member are respectively brought into contact with the two side faces of the vertical frame main body, and the screws are screwed into the screw engagement portions of the vertical frame main body through the screw insertion holes of the angle member.

That is, since the two side walls of the angle member are connected in contact with the two side faces of the vertical frame body, after the screwing, the two contact faces interfere with each other to create a gap. Therefore, rattling is less likely to occur and the strength of the vertical frame is improved. Further, even if the horizontal frame is welded in advance, the product display wagon can be assembled at the site by connecting the vertical frame body and the angle member, and the assembling work can be easily performed.

Further, after the assembly, the vertical frame is composed of a rectangular column-shaped vertical frame body and angle members abutting on two side surfaces thereof, which is more than the conventional two column-shaped column support. It is not bulky and can improve the appearance.

Therefore, in the product display wagon assembly structure according to the present invention, it is possible to improve the appearance of the vertical frame and improve the strength of the vertical frame.
