Description

The present invention relates to a top and bottom support device that is erected between roofs and roofs of buildings, between grounds of ceilings, furniture, and the like, between large pulls under the floor and between grounds, and other tops of buildings.

Resin and steel devices are commonly used as ceiling and furniture top and bottom support devices, but in recent years, two bolts with the same screw direction are screwed up and down for height adjustment. A structure that adjusts the height is known.

For example, if you look at the height adjustment technique in Japanese Patent Publication No. 8-308661, you can see the technique of turning two bolts in the same screw direction up and down and the right and left screws on the top and bottom respectively. A so-called turnbuckle method technique for adjusting the height is disclosed.

Resin and steel are also popular as support devices under the floor, but with regard to height adjustment, a turnbuckle method that adjusts the height by applying right and left screws to the top and bottom of the bolt respectively. Most of the structures used are used.

For example, see Japanese Patent Application Laid-Open No. 2002-147001, which is the invention of the present applicant. Each pipe is welded to the upper and lower plates, one of the two pipes is a right-hand thread and the other is a left-hand thread. In the middle screw bolt, left and right screws are applied to the left and right, respectively, so that the height of the pipe can be adjusted up and down by the turnbuckle method.

In Japanese Patent Publication No. 8-308661 shown in [0003], two bolts are fixed on the top and bottom, and two female screws for screwing are fixed on the wooden pipe used in the middle. In terms of both the number of parts and the number of processing steps, the cost becomes high.

Further, in the turnbuckle method found in Japanese Patent Application Laid-Open No. 8-308661 and Japanese Patent Application Laid-Open No. 2002-147001, the right and left screws must be processed separately for the pipe and the bolt, respectively, and the number of processing steps is doubled. There is also a problem that this will also be expensive.

Furthermore, a nut provided with a protrusion as a part for preventing loosening of a bolt found in Japanese Patent Application Laid-Open No. 2002-147001, but this also has a drawback that it is more expensive than a commercially available nut because of special processing.
