JPS5934728Y2 - Holder for connecting vertically grooved pole and horizontal frame - Google Patents

Description

[Detailed description of the invention] The present invention is a connecting metal holder that has recently been used to connect vertical and horizontal members of furniture such as decorative shelves and fittings such as partitions. The object of the present invention is to provide a metal holder of this type for connection that can be mass-produced at low cost and that can easily, reliably and firmly connect the pole and the horizontal bar.

Conventional holders of this type have a so-called clothespin-like structure in which each holder half is set as a set on the left and right or the top and bottom, and a spring is interposed between these halves, or they are assembled with a spring and a support shaft. ,
In addition to this, there is also a type in which one holder half is assembled with the other holder half in a lever shape, and these half holders are assembled with screws, but these are all made from three or more parts, so it is difficult to manufacture. It requires two or more types of molds and extra materials, and it takes time and effort to assemble, which not only makes it expensive, but also causes the holder to loosen or shift after the pole and horizontal bar are connected, which causes the joint to move uncontrollably. There are drawbacks to this.

In addition to the above, there are also products made of a single member, but in the conventional one, a screw or the like is inserted from the top between the two prongs of the holder body bent in a U-shape, and the holder is split open and bifurcated. Each hook at one end is engaged with the groove edge of the other vertical member, but in such a case, the outer periphery of the screw is simply interposed between the two prongs in tangential contact, so the two prongs are The holder is likely to be displaced, twisted, or tilted downward, and therefore, when a heavy object is placed on the horizontal member and collides with it, there is a risk that the holder will slide off along with the holder.

In order to eliminate the above-mentioned disadvantages, the present invention proposes the following simple and effective holder of this type.

That is, as shown in the drawings of the embodiment, an integral metal member is provided with engagement recesses 3, 3' having approximately wedge-shaped cross sections in plan on the outside of each tip 2, 2', connected to a base 4 bent in a U-shape in plan. The belt-shaped main bodies 1 and 1' are protruded in parallel, and a screw 6 is inserted through a screw hole 5 bored in the side surface of the approximately middle part of one main body 1, and its tip surface is brought into contact with the inner surface of the other main body 1'. In contrast to the known light metal vertically grooved rectangular pole 7 which has a rectangular hole H in the center and vertical grooves on the four outer sides, it has a rectangular hole H in the center.
', When horizontally mounting a known horizontal grooved horizontal frame 8 made of light metal with horizontal grooves L' formed on the four outer sides, first insert the main holder into the square hole H' in the horizontal frame from the U-shaped bent part 4. and position the tip portions 2, 2' to protrude from the end of the square hole,
Next, the flat screw 6 is inserted through the insertion hole R formed in the horizontal groove L' on one side of the horizontal frame 8, and screwed into the screw hole 5 in the middle part of the side of the main body 1 of the book holder. After that, the horizontal frame 8 is attached to the side surface of the square pole at the desired height.
The end of the holder is brought into view, and the tips 2, 2' of the holder protruding from the end of the square hole H' are squeezed slightly to make them constricted and inserted into the vertical groove of the square pole 7, and then the screw is inserted. When screwing in 6 further, its tip surface comes into contact with the inner surface of the other main body 1' and then gradually presses from the inner surface, so that both main bodies 1 and 1' are expanded and the tips of the main bodies 1 and 1' are pushed outward by 2°2'. The respective engaging recesses 3 and 3' are tightly engaged with the left and right groove edges F of the vertical groove in the square pole 7, so that the horizontal groove L' of the horizontal frame 8 and the corner The end faces including the hole H' are mounted in a close-overlapping manner, and F' in the drawing is the groove edge of the lateral groove L'.

As described above, the main body of the holder is made of a single piece, so the mold can be extruded in a single process, and no assembly work is required, so it can be mass-produced very efficiently. Of course, it does not have the disadvantages of conventional two-part holders and can be provided at a low price, but in particular, the holder of this invention has a spiral hole on one side of the main body that extends parallel to the U-shaped bent base. The inserted screw is inserted through the insertion hole in the horizontal frame, and the tip of the screw presses the other main body from the inside, causing both main bodies to expand, so the expanded state can be maintained immovably, but the holder will not shift. Therefore, the engagement recess at the tip maintains a securely engaged state, but it is unstable and lacks the holding force like the conventional crotch-opening holder, and as a result, the horizontal bar may slide. It has the effect of eliminating the risk of transfer, and is an extremely advantageous device that is easy to manufacture and use for this type of holder.
