Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tension strut in which inner and outer tubes are extended between upper and lower surfaces facing each other, and are supported by being stretched.

(Prior art) Conventionally, as a tension support, for example,
Like the prop described in Publication No. 31219, there are some that attach a pressing device to the prop and extend the outer tube (outer column) and inner tube (inner column) to support and fix the column to a window frame or the like. In addition, like the prop described in Publication No. 48-93215, it can be fixed to a sash etc. with bifurcated locking pieces (clamping metal fittings) attached to the upper and lower outer ends of the extensible and adjustable prop. There is something I did.

(Problem to be solved by the invention) However, in the prior art described above, in which a pressing device is simply attached to a support, in order to extend and fix the support, the upper and lower surfaces of the fixing point (the upper and lower end surfaces of the support The problem is that it can be installed only if the surface it touches (the surface it touches) is fairly wide, and if the installation location is narrow, it is difficult to securely fix it. On the other hand, a structure in which two-pronged locking pieces are simply attached to the upper and lower outer ends of the support can be attached when there is a window frame such as a sash at the fixed location. That is, all of the above-mentioned conventional techniques have the disadvantage that the fixing locations are limited.

The object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide a tension support that can be easily attached to either a picture frame or a sash for a window in a room.
