Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a wooden table leg attachment device for easily and securely attaching a wooden table leg to a wooden table.

[Prior Art] Conventionally, the legs of a wooden table are attached to the lower surface of the top plate of the wooden table by using a mounting bracket so that the legs are closely attached to the inner surface angle of the curtain plate provided around the lower surface of the top plate. It was installed.

However, recently, many tables have no curtain plate.

Therefore, when attaching the legs to the top plate without the curtain plate, a so-called demon nut embedded in the top plate and having a plurality of protrusions on the outer periphery, and a screw embedded in the upper end of the leg and protrudingly engaged with the demon nut are screwed. It used a mounting bracket consisting of a rod.

[Problems to be solved by the invention] However, with this mounting bracket, when the top plate is thin, it is difficult to embed the demon nut, and the screw rod is embedded in the upper ends of the legs. It required time-consuming work.

Further, when used for a long period of time, the screwing of the demon nut and the screw rod was loosened, which sometimes deteriorated the stability of the table. Therefore, there are inconveniences in use, in which the legs are sometimes rotated to eliminate looseness.

The present invention has been made in view of such problems, and the legs can be easily attached to the top plate regardless of the thickness of the top plate of the table, and the legs can be attached to the top plate even when used for a long period of time. An object of the present invention is to provide a mounting device for a wooden table leg that is securely mounted and fixed.

[Means for Solving Problems] Means for solving the above problems will be described with reference to FIGS. 1 to 7 corresponding to the first embodiment.

The table leg attaching device A includes a board 15 attached with wood screws 14 so that a gap 13 is formed in a dug recess 12 formed on a lower surface 11 of a top plate 10 of a table T, and a wood screw attached to an upper end 16 of a round leg La. It is composed of a mounting plate 17 mounted by means of 14, and a fixture 18 composed of a bolt for closely fixing the mounting plate 17 to the substrate 15.

As shown in the plan view of FIG. 3 and FIG. 4 which is a cross-sectional view taken along the line IV-IV of FIG. 3, the substrate 15 has a shape in which a circular head is integrally formed with a substantially triangular tapered portion. The rising ribs 20 are formed on the periphery. A rectangular engaged hole 21 with which a tongue piece 30 of a mounting plate 17 described later is engaged is formed slightly on the left side of the center. Four wood screw holes 22 are formed at equal intervals on a circle centered on the center point of the circle of the circular portion of the substrate 15. The tapered portion of the substrate 15 is provided with a through hole 23 through which the fixture 18 penetrates. A nut 24 to which the fixing tool 18 is screwed is welded to the surface of the through hole 23 on the substrate 15.

The board 15 having the above-described shape is attached with the wood screw 14 penetrating the wood screw hole 22 to the dug recess 12 formed in the lower surface 11 of the top plate 10 in the same shape as the board 15 in advance with the rib 20 facing upward. As a result, the rib 20 creates a gap 13 between the dug recess 12 and the substrate 15.

The mounting plate 17 has the same shape as the substrate 15, as shown in the plan view of FIG. 5 and FIG. 6 which is a sectional view taken along the line IV-IV of FIG. A tongue piece 30 having an L-shaped cross section that engages with the engaged hole 21 formed in the substrate 15 is formed by cutting and raising slightly to the left of the center of the mounting plate 17. In this case, the rising angle α (FIG. 6) of the tongue piece 30 is slightly larger than 90 °, and the tip bending angle β (FIG. 6) is almost 90 °.
