Construction element adjustable in length by pulling out, especially curtain rod

The innovation concerns an adjustable length by pulling out Construction element, in particular a curtain rod, with at least two telescoping one into the other arranged tubes, the inner with a locking element acting opposite the outer is provided.

The previously known construction elements of the above type have the disadvantage that the _three Verriegelungselenent used in them awkward in its installation and / or expensive to manufacture and transferable by the locking element force is very limited.

The purpose of the innovation is to create an extendable construction element, in particular a curtain rod that does not have these disadvantages.

The structural member, in particular curtain rod, of the type mentioned is, neuerungsgeinäss characterized in that the locking element as a spring element which projects beyond _s sindestens at a location in the unstressed condition the inner cross section of the outer tube, excluded

forms is such that it is only opposite to the pull-out direction has a locking effect.

The construction element according to the innovation can also be used as a self-tightening, Can be put together as a tent pole or as a book pole that can be clamped between the floor and the ceiling.

The innovation is explained in more detail below with reference to the drawing. Show it:

1 shows an exemplary embodiment of a curtain rod trained construction element according to the innovation;

2 shows a plan view of a first exemplary embodiment of the spring element used in Figure 1;

3 shows a plan view of a second exemplary embodiment of the spring element used in Figure 1; and

FIG. 4 shows a plan view of a further exemplary embodiment of the spring element used in FIG. 1.

The curtain rod shown in Fig. 1 consists of two nested tubes, namely the outer tube 1 and the inner tube 2, the total length of the two tubes 1 and 2 must be greater than the distance between the two wall parts j5 and k, between which the rod is to be attached.

At the end of the inner tube 2, which is located in the outer tube 1, a compression spring 5 is fixedly arranged, the end facing away from the inner tube 2 for holding and support of the locking element 6 is used. The locking element 6 shows a view in the pull-out direction of the rod

concave spring element 7, behind the * prevention a support disk 8 is arranged when the latter snaps over is.

At the ends of the rod is to avoid damage the two wall parts 3 and 4 each have a rubber stopper 9 and 10, respectively arranged.

In FIGS. 2 to 4, for example, embodiments of the spring element 7 shown in FIG. 1 are shown.

With an inner diameter of 19 mm of the outer tube 1 has the illustrated in Fig. 2, designed as a spring washer spring element 7 in the flat state expediently around 0.5 to 1.0 iron larger diameter and a thickness of 0.2 mm on. To increase flexibility, the disk is provided with radially extending slots 11. The concave shape the disk 7 results when it is inserted into the outer tube I. The assembly of the rod takes place as follows: The two tubes 1 and 2 are opposed to the frictional force exerted on the outer tube 1 by the peder element 7 pulled apart until the length of the rod measured over the plug 9 and 10 is greater than the distance between the two wall parts j5 and 4. Thereupon, the rod is against the by the locking element β on outer tube 1 supported spring 5 compressed force exerted and inserted between the two walls! Ie 3 and 4, vio they are clamped under the action of the spring 5 can"

If the rod is pulled too far apart to be wedged between the two wall parts 3 and 4, then the two plugs 9 and 10 at the rod ends are to be removed and the two tubes 1 and 2 completely removed To pull engagement with each other, whereupon the locking

element 6 opposite end of the inner tube 2 is re-inserted into the outer tube 1 until I the desired rod length has been reached. Afterwards the

L both plugs 9 and 10 reinserted; whereupon the pole

j can be wedged between the two wall parts.

j The bar described shows, in addition to the simple training

{·, The locking element has the additional advantage,

that it can be used for distances, polygamy approximately between-I see the length of the pipe 1 and the length of the pipes 1 and

ι 2 lying together.
