Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support leg for holding a floor material above a double floor at a constant height.

[0002]

[Prior art]

 The conventional double-floor support leg has a structure in which a bolt is planted in the center of the board, a nut portion is screwed onto the bolt, and a pedestal for supporting the floor material is provided above the nut portion.

[0003]

[Problems to be solved by the device]

 With conventional double-floor support legs, the height is adjusted by rotating the nut and changing its position, so the height adjustment range is limited by the length of the bolt and the length of the nut. Therefore, the height adjustment width was narrow, and it was necessary to prepare support legs of various sizes. Moreover, the height adjustment requires many rotations of the nut portion, which is time-consuming and time-consuming. Further, since the bolt and the substrate extend in the directions orthogonal to each other, they have a large occupied space for storage and transportation and are difficult to be loaded, resulting in poor storage and transportation efficiency.

The problem to be solved by the present invention is to solve these problems of the prior art, to provide a wide height adjustment range, which enables quick and quick adjustment, and which is easy to store and transport. To provide legs.

[0005]

[Means for Solving the Problems]

 The gist of the present invention which solved such a problem is as follows: 1) A right leg plate, a pedestal mounting plate, and a left leg plate are sequentially pivotally attached to each other at one end of one end of a base plate having a plurality of locking grooves and directly connected to each other. Double floor support leg in which the free end of the leg plate is engaged with the locking groove and a pedestal for supporting the floor material is attached to the pedestal attachment plate 2) Along the longitudinal direction of the right leg plate and the left leg plate The double floor support leg according to claim 1, wherein a plurality of hook holes are provided, and connecting metal fittings are hooked between required hook holes of the left and right leg plates. 3) A plurality of hooks are provided on the bent side end surface of the board. The pin hole is provided, a pin hole is also formed at the free end of the left leg plate, and a stopper pin is inserted into the pin hole at the free end of the left leg plate and the pin hole at the side end surface of the substrate. Or the support leg for double floor according to claim 4) The support for double floor according to any one of claims 1 to 3, wherein the pedestal is detachably attached to the pedestal mounting plate. Located in.

[0006]

[Action]

 In the present invention, since the right leg plate, the screw mounting plate, and the left leg plate are pivotally connected to each other, they can be brought into the open state with the required angle. The angle of the spread leg can be changed by moving the left leg plate left and right along the board from 0 ° to nearly 90 °, which allows the height of the central screw mounting plate to be freely and quickly adjusted. When the desired open leg angle (height of the pedestal mounting plate) is reached, the open state can be maintained as it is by engaging the free end of the left leg plate with one of the locking grooves of the board. The floor material is supported by the left and right leg plates and a screw mounting plate via the pedestal.

Here, in the case where the connecting metal fittings are hooked in the hooking holes of the left and right leg plates, the open leg is surely held. Further, even if one of the pin holes provided on the bent side end surface of the substrate and the pin hole at the free end of the left leg plate are inserted with the stopper pin, the open leg state is surely maintained. When combined with the above-mentioned open-leg holding by locking the metal fittings, the required open-leg state can be held more reliably. If the pedestal is attached to the pedestal mounting plate in a detachable manner, storage and transportation can be performed easily because it can be stored and transported in two parts: a folded base plate, left and right leg plates, the pedestal mounting plate, and the pedestal.
