[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting leg for holding a floor material above a double floor at a constant height.

[0002]

2. Description of the Related Art A conventional double-floor support leg has a structure in which a bolt is planted in the center of a board, a nut portion is screwed to the bolt, and a pedestal for supporting a floor material is provided above the nut portion. there were.

[0003]

In the conventional double-floor support leg, the height is adjusted by rotating the nut portion and changing its position. Therefore, the height adjustment width is the length of the bolt,
Since the length of the nut is limited and the height adjustment width is narrow, it was necessary to prepare support legs of various sizes. Further, height adjustment requires many rotations of the nut portion, which is time-consuming and time-consuming. Further, since the bolt and the board extend in directions orthogonal to each other, the shape has a large occupied space for storage and transportation and is difficult to be loaded.
The storage and transportation efficiency was poor.

The problem to be solved by the present invention is to solve these problems in the prior art, to provide a wide height adjustment range, to enable quick adjustment, and to easily store and transport double-floor support legs. To provide.

[0005]

Means for Solving the Problems The gist of the present invention which has solved the above problems is as follows: 1) A right leg plate, a pedestal mounting plate, and a left leg plate are sequentially attached to one end of a base plate having a large number of locking grooves. Double floor support legs which are pivotally attached to each other and directly connected to each other, the free end of the left leg plate is engaged with the locking groove, and a pedestal for supporting a floor material is attached to the pedestal attachment plate 2) a right leg plate and The support leg for a double floor according to claim 1, wherein the left leg plate is provided with a plurality of hook holes along the longitudinal direction thereof, and the left and right leg plates are connected by hooking connecting metal fittings between the required hook holes. In addition to providing multiple pin holes on the bent side end surface of the left leg plate, a pin hole is also formed at the free end of the left leg plate, and the pin hole on the free end of the left leg plate and the pin hole on the side end surface of the board are formed. A support leg for a double floor according to claim 1 or 2, wherein a stopper pin is inserted therethrough. 4) A pedestal detachably attached to a pedestal attachment plate.
The support leg for a double floor according to any one of 3 to 3.

[0006]

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 opened with a required angle. The angle of spread legs is 0 ° to 90 °
It can be changed by moving the left leg plate to the left and right along the board to the near, which allows the height of the central screw mounting plate to be freely and quickly adjusted. When the desired leg opening angle (height of the pedestal mounting plate) is reached, the free leg 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 the screw mounting plate via the pedestal.

[0007] Here, in the case where the connecting metal fittings are hooked in the hooking holes of the left and right leg plates, the open legs can be reliably 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. In addition to holding the open leg by hooking the connecting metal fittings, the required open leg state can be held more reliably. In the case where the pedestal is attached to the pedestal mounting plate in a detachable manner, the storage / transportation can be folded board, left and right leg plates,
Since the pedestal mounting plate and the pedestal can be divided into two parts, they can be stored and transported easily.

In the figure, 1 is a board, 2 is a locking groove provided in a large number on the board 1, 3 is a right leg plate, 4 is a pedestal mounting plate, 5 is a left leg plate,
6 is a pedestal, 7 is a floor material, 8 is a hook hole provided on the bent side wall of the right leg plate 3, 9 is a hook hole provided on the bent side wall of the left leg plate 5, and 10 is a connecting fitting. 11 is a pin hole provided on the bent side end surface of the substrate 1, 12 is a pin hole provided on the side wall of the free end of the left leg plate 5, 13 is a stopper pin, and 14 is a pivot shaft between the substrate 1 and the right leg plate 3. , 15 is a pivot shaft between the right leg plate 3 and the base mounting plate 4, 16 is a pivot shaft between the base mounting plate 4 and the left leg plate 5, 1
7 is a tapered free end of the left leg plate 5, 18 is a bolt hole drilled in the pedestal mounting plate 4, 19 is a bolt hung vertically from the center lower surface of the pedestal 6, 20 is screwed to the bolt 19, and the pedestal 6 is mounted on the pedestal. An adjustment nut fixed to the plate 4 and a nut 21 fixed by welding under the bolt hole 18 of the base mounting plate 4.

In this embodiment, the left leg plate 5 is moved along the base plate 1 and stopped at the position of the required leg opening angle, and its tapered free end 17 is engaged with one locking groove 2 of the base plate 1. hand,
Fix the open legs. Next, in order to hold the open leg more reliably, the connecting metal fitting 10 is attached to the left and right leg plates 5 and 3 with the required hook holes 8.
Connect to connect. Further, the stopper pin 13 is inserted into one of the pin hole 12 provided near the free end 17 of the left leg plate 5 and the pin hole 11 provided on the bent side end surface of the substrate 1 so that the left leg plate 5 does not move. So that it is fixed. For fine adjustment of the height of the pedestal 6, two upper and lower adjustment nuts 2 screwed to the bolts 19 of the pedestal 6 inserted into the bolt holes 18 of the pedestal mounting plate 4 are used.

[0012]

As described above, according to the present invention, the height of the pedestal can be quickly adjusted by the openable and closable left and right leg plates and the pedestal mounting plate. The height adjustment range is wide. The one in which the connecting metal fitting is hung over the hook hole and the one in which the pin hole at the free end of the left leg plate and the pin hole in the substrate are penetrated by the stopper pin can more reliably maintain the required open leg state. . When the legs are opened, the height is low, which is advantageous for storage and transportation. In particular, if the pedestal can be removed from the pedestal mounting plate, the board side can be loaded and stored / transported, which facilitates storage / transportation.
