あつた。(Prior art and its problems) The present applicant previously proposed a so-called screw jack type furniture height adjustment device. That is, a vertical rotating screw shaft whose upper end is supported within a furniture mounting case and whose lower end has a stopper for preventing the lifting body from coming off;
Although we have proposed a furniture height adjustment device that includes an elevating body screwed onto this screw shaft, a base attached to the lower end of this elevating body, and means for rotating the screw shaft, this conventional furniture height adjustment device has been proposed. The adjustment device had a structure in which the nut of the elevating body had to be screwed onto the screw shaft from the top end of the screw shaft, so it was necessary to have a straight small diameter shaft section at the top end of the screw shaft. However, there was a drawback that the support structure of the upper end of the screw shaft was restricted.

点にある。(Means for solving the problems) The present invention proposes a furniture height adjustment device that can solve the conventional problems as described above.
The feature is that the elevating body is composed of a nut consisting of two parts that sandwich the screw shaft from both the left and right sides, and a cylindrical body that is externally fitted and fixed to the nut, and that protrudes laterally from the upper end of the nut. The second feature is that the rotation preventing protrusion is fitted into the elevating guide groove formed in the case.

By lowering the base 4 and pressing it against the floor surface, the furniture is prevented from wobbling, but the height of the furniture can be adjusted by raising and lowering the base 4 using the tool fitting groove 23 of the small bevel gear 21. small bevel gear 2
1, and the rotation of the small bevel gear 21 is transmitted from the large bevel gear 20 to the helical shaft 2 via the square shaft portion 10 of the helical shaft 2, or the tool fitting groove 2 at the upper end of the helical shaft is rotated.
2 to directly rotate the screw shaft 2 and lift the elevating body 3.
This is done by moving up and down. At this time, the nut 13 constituting the elevating body 3 is in a state where it can only be raised and lowered because the rotation preventing protrusion 17 is fitted into the elevating guide groove 30 on the case body 6 side, so it is integral with the screw shaft 2. There is no mutual rotation.

ないで済む。(Operations and Effects of the Invention) According to the furniture height adjustment device of the present invention which can be implemented as described above, there is no need to fit the nut constituting the elevating body from one end of the screw shaft. This is a screw shaft that has parts larger in diameter than the screw shaft, such as a bearing seat and a square shaft for stopping bevel gear rotation, integrally molded on the upper end, and a stopper for preventing the elevating body from falling off on the lower end. can be used. Therefore, in order to allow the screw shaft to rotate smoothly, the upper end of the screw shaft is directly supported by a thrust bearing, and the large support reaction force acting on the screw shaft is transmitted to the joint between the screw shaft and the bevel gear, and There is no need to act on the bevel gear itself.
