Description

[Detailed Description of the Invention] This invention relates to a table leg attachment device.

A conventional table leg attachment device used in a hori kotatsu is shown in FIG. That is, a pair of curtain plates 2 and 3 are connected to the upper surface of the leg 1, a connecting fitting 4 as shown in the figure is brought into contact with the inside of the leg 1 and the curtain plates 2 and 3, and a threaded rod 5 protrudes from the leg 1. By tightening the nuts 6 to integrate the legs 1 and the connecting metal fittings 4, and by integrating the curtain plates 2, 3 and the connecting metal fittings 4 with the tap screws 7 to 14,
The legs 1 and curtain plates 2 and 3 are integrated.

However, this table leg attachment device is
The two screws 7 to 14 and one threaded rod 5 are used to fix each other, and there are problems in that assembly is difficult and the knock-down method is difficult.

Therefore, the purpose of this invention is to provide a table leg mounting device that is easy to assemble, allows easy adoption of the knock-down method, provides firm fixing, saves materials for connecting fittings, and is simple to manufacture. be.

An embodiment of this invention is shown in FIGS. 2 to 4. That is, in this table leg attaching device, the connecting fitting 15 is formed as follows. That is, the end face of the lower piece 16 which becomes the lower flange of the U-shaped fitting extends by a dimension P from the end face of the upper piece 17 which becomes the upper flange, and the tongue pieces 19 and 20 extend from both sides of the web 18.
are bent and extended at right angles to each other, and their tips 21 and 22 are bent at right angles, and both side ends 23 and 24 of the upper piece 17 are attached to the tongue pieces 19,
20 along the extending direction (45 degrees to the web 18), and both ends 2 of the lower piece 16.
5 and 26 are cut within a range of a slightly obtuse angle with respect to the tongue pieces 19 and 20 (55 degrees with respect to the web 18 in the figure).

On the other hand, the leg 27 has an embedded nut 28 formed on the back surface of its upper side and a horizontal groove 29a below which the tip edge 16a of the lower piece 16 of the connecting fitting 15 enters.
At the same time, a horizontal groove 29b into which both ends 25, 26 of the lower piece 16 of the connecting fitting 15 enter is formed in the curtain plates 30, 31 continuously with the horizontal groove 29a, and the tips of the tongue pieces 19, 20 Vertical grooves 32 and 33 into which the parts 21 and 22 fit are formed.

The legs 27, the curtain plates 30, 31, and the connecting fitting 15 are connected to each other by drilling a bolt insertion hole 34 in the web 18 of the connecting fitting 15, passing the bolt 35 through it, and screwing it into the embedded nut 28. 19,20
Screw insertion holes 36 to 39 are drilled in each of them, and tap screws 40 to 43 are screwed into the curtain plates 30 and 31.

With this configuration, the legs 27 and the connecting fittings 1
5 is fixed by pressure contact with the U-shaped upper piece 17 and lower piece 16, so it can be made sturdy, and the horizontal grooves 29a, 2
By entering the lower piece 16 into 9b, the vertical displacement between the leg 27 and the curtain plates 30, 31 is reliably regulated, thereby eliminating the need for the conventional connecting fittings to abut and fix on the lower surface of the curtain plate. Horizontal grooves 29a, 29
b allows the positioning of the legs 27 and curtain plates 30, 31 to be set in advance, and the tips 2 of the tongue pieces 19, 20
The engagement with the vertical grooves 31 and 32 of Nos. 1 and 22 reinforces the horizontal displacement, that is, the horizontal fall control. As a result, assembly can be carried out using one bolt 35 and four tap screws 40 to 43, and positioning is easy, making it easy to adopt the knock-down method. In addition, since the connecting fitting 15 is U-shaped, it is different from, for example, a block-shaped one, a flat plate-shaped one, or one made by assembling flat plates into a block-like shape. It is possible and easy to manufacture.

As described above, the table leg mounting device of this invention continuously forms horizontal grooves on the inside of the legs and curtain plate,
Since the legs and curtain plate are connected and integrated using a U-shaped connecting metal fitting with a piece that enters into contact with this, assembly is improved compared to the conventional method, the knock-down method is easier, and firm fixation can be performed. Moreover, it has the effect of saving materials and simplifying the manufacturing of the connecting fittings.
