JP2002320518A - Position-fixing device for table leg - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a position-fixing device for a table leg which device has a simple structure, can fix the opening angle of a pair of arch-shaped folding legs with one action and solves the problem that it is difficult to find an appropriate opening angle of the pair of arch-shaped folding legs because, in a conventional structure, an arch-shaped folding table leg cannot be set to fix it firmly unless a leg top is located at the exact fixing position of a table top board. SOLUTION: A table having rotation-folding arch-shaped legs uses a table-leg position-fixing device comprising an upper wave-shaped disk 4-1, a lower wave- shaped disk 4-2, a pressurize elastic body 4-3 and a fixing bolt 4-4.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-walled table leg which is paired with two double-walled legs as shown in FIG.

[0002]

[Prior art]

[0003]

The conventional product has the disadvantages as described in the previous section. Therefore, when the pair of portal legs are rotated and deployed, the mounting bolt portion serving as the center of rotation is devised, and if it is said to be in a soft lock state or is being rotated, it is intermittently softly locked and estimated. When stopped at an angle, it will be locked at the deployment angle that exactly fits the mounting position of the top plate,
There is a need for a table leg position setting tool that does not require fine adjustment and determines the deployment angle in one shot. The present invention has been made to solve the above problems.

SUMMARY OF THE INVENTION In a table having a rotating and retractable portal-type leg, an upper corrugated disk 4-1 and a lower corrugated disk 4-2, a preload elastic body 4-3, and a fixing bolt 4-4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a state in which the product of the present invention is used. The table is fixed by fitting a pair of gate-shaped legs 2 to a glass top plate 1 with leg joints 3 provided at four corners of the top plate 1. Have been. A pair of portal legs 2 are leg cross beams 2-
The table leg position setting tool 4 according to the present invention is deployed at the intersection of the two with the rotation center as the center of rotation. Figures 2-3
As shown in the figure, the upper corrugated disk 4-1 and the lower corrugated disk 4-2 are arranged between the crossed leg cross beams 2-2, and the leg cross beam 2-2 is provided.
A disc spring is provided on the upper surface of the flat plate as a flat washer 4-5 and a preload elastic body 4-3, and is attached with a fixing bolt 4-4. In addition, since the disc spring is tightened by the fixing bolt, a preload is applied to the corrugated surface of the disk, and the disc is locked with an appropriate force at the position where the peaks and valleys of the disc fit. The waveform pitch of the disc is determined so that the pair of portal legs 2 and the leg engaging portions 3 at the four corners of the top plate match the flat closed position when stored.

[0006]

The use of the present invention simplifies assembly, a major drawback of a table having a rotating and retractable portal leg. In addition, when closed flat during storage or transportation, it is soft but locked in that state, which is convenient for handling.
