Description

[Detailed Description of the Invention] The present invention relates to a structure for connecting columns and horizontal bars in display fixtures.

Conventionally, in display fixtures such as display shelves and display stands,
The posts are connected to each other by placing a cross bar between the upper ends of the posts. The posts are connected to the cross bar by screws or by engaging a locking portion formed on the end of the cross bar with a locking hole drilled in the post.

However, such a conventional connection between the pillars and the horizontal beams is time-consuming, and the joints between the pillars and the horizontal beams tend to wobble, making it difficult to connect easily and reliably.

In view of these conventional drawbacks, the inventor of the present invention has made extensive efforts to provide a structure for connecting columns and horizontal bars in display fixtures that eliminates the above-mentioned drawbacks.

The present invention will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes a support, which is a hollow body made of metal such as iron, aluminum, stainless steel, or the like. The strut 1 usually has a rectangular cross section, and has two vertically extending upwardly opened notches 11 arranged side by side on at least one side of the upper end. In the case of Figures 1 to 4, there are notches 11 and 11 on opposite sides of the support 1, respectively.
...is formed. In addition, reference numeral 12 denotes display fixture locking holes arranged in a row along the length direction of the support column 1;
3 is a pedestal.

Reference numeral 2 denotes a horizontal crosspiece, which is made of metal such as iron, aluminum, or stainless steel. The cross section of the horizontal bar 2 is not particularly limited, and may be rectangular, circular, grooved, or the like. A vertical locking hole 2 is provided at the end of the horizontal bar 2.
A locking protrusion 21 having a diameter of 2 is formed. As shown in FIG. 1, the locking protrusion 21 is formed into a substantially U-shape by bending both ends of a plate piece in the same direction, and its width is approximately equal between the notches 11 of the support column 1.

3 is a cap, which is made of metal such as iron, aluminum, stainless steel, synthetic resin, or the like. The cap 3 is formed by a leg piece 32 hanging from the lower end of a main body 31. Main body 31
is a plate piece shaped to fit the upper end surface of the support column 1, and the leg piece 32 is made slightly wider than the inner diameter of the support column 1, and is notched in two places in the vertical direction as shown in FIG. It is divided into leg pieces 34, 34. The central leg piece 33 has a notch 11 in the support column 1,
The width is approximately equal to or smaller than 11.
As shown in FIG. 1, the end leg piece 34 is tapered at the lower end so that it can be easily fitted into the support column 1, and a pressing protrusion 35 is formed on the opposite side from the center leg piece 33. ing. The leg piece 32 is simply 1
Although it is possible to have only one piece, usually they hang down from opposite ends of the lower surface of the main body 31, as shown in FIG.

Next, a method of connecting the support 1 and the horizontal beam 2 will be explained.

First, the locking protrusions 21 of the horizontal beam 2 are locked in the notches 11, 11 of the support column 1 as shown in FIG. Next, as shown in FIG. 3, the locking hole 22 of the locking protrusion 21, specifically, the inner surface of the support 1 between the notches 11, 11 and the locking protrusion 2.
The center leg piece 33 of the cap 3 is fitted into the gap surrounded by the support column 1, and the end leg pieces 34, 34 are fitted between the inner surface of the column 1 and the locking protrusion 21.
At this time, the pressing protrusions 35, 3 of the end leg pieces 34, 34
5 presses the inner surface of the support column 1 to release the end leg pieces 34, 34.
is fitted into a wedge shape between the inner surface of the support column 1 and the locking protrusion 21. In the case of Figures 1 to 3, leg piece 3
One leg piece 32 which is not used for connecting the horizontal beams 2 and 32 is inserted into the support column 1 as it is.

In addition, in the case of FIG. 4, notches 11, 11, . The leg pieces 32, 32 are each fitted into the support column 1 in a wedge-like manner in the same manner as described above.

Moreover, FIG. 5 shows a state in which the horizontal bar 2 is stretched between the upper ends of the columns 1 and 1 as display fixtures,
The method of connecting the horizontal beams 2 and 2 may be similar to those shown in FIGS. 2 and 3.

As detailed above, in the connecting structure of the present invention, the locking protrusion at the end of the horizontal beam is locked in the notch at the upper end of the column, the central leg piece of the cap is fitted into the locking hole of the locking protrusion, and Since the end leg pieces are each fitted in a wedge shape between the inner surface of the column and the locking protrusion, the column and the horizontal beam can be easily and reliably connected without rattling.

Furthermore, since the locking protrusions of the horizontal beams and the leg pieces of the cap are connected to each other so as to be located within the pillars, the appearance can be maintained without exposing the connecting portions of the pillars and the horizontal beams to the outside.
