Schäper, Clemens, Raiffeisen-Str. 4, 4400 Münster - Roxel "Holding and tensioning device for sports nets"

The invention relates to a holding and tensioning device for a sports net, such as a volleyball net or the like. with a support post and a clamping device which can be fixed in a height-adjustable manner on this support post.

In particular with volleyball nets the problem arises that the net is arranged relatively high and has a great length Set between the two playing fields with sufficient tension so that a proper jumping off of the ball reaching the net is ensured. The previously known clamping devices consist of ratchet-like ones Devices that are arranged on the side of the support post facing the network and, by actuating them, the upper tension rope deflected over a pulley or a hook can be tensioned. The clamping path in these known devices is relatively low.

However, it has proven to be particularly disadvantageous in the case of the known devices found that in that they are arranged on the side of the post facing the network, the network holds that injuries to the players can occur here during the game, which must be avoided at all costs.

The invention is therefore based on the object of a clamping device to create that allows a large tensioning path and still on the side facing away from the actual Post is arranged without, however, independent of the post components are used to tension the network must, such as in gyms the side walls or the like,

This object on which the invention is based is achieved, in particular, by the measures specified in the claims by means of a clamping post that can be locked at different heights on the support post. This post instructs its upper end, above the upper end of the clamping post on a pulley and thus leads the upper Tension rope of the net on the side of the tensioning post facing away from the net, on this side then according to another A very important feature of the invention is a tensioning unit which consists of two telescopic, mutually adjustable Components exists and which is itself adjustable in turn on the clamping post, so that a very wide Span can be achieved.

Further advantageous configurations of the devices according to the invention are explained in the subclaims. In particular, it is very important that the actual clamping unit consists of two There is spindle-operated telescopic tubes, one tube, preferably the outer tube, fixed to the clamping post is, while the inner tube carries the upper tensioning cable and

Apart from these explained adjustment and clamping possibilities The invention also gives the possibility that the clamping post can be adjusted relative to the stand post, so that this allows large adjustments to the net height, for example when setting the net to children or adults is.

means, screwing means or other holding means in its | Altitude can and must be determined, of course **.

An exemplary embodiment of the invention is given below with reference to §

% of the drawing explained.

In the drawing, 1 denotes a volleyball net, which consists of an upper tensioning cable 2 and a lower tensioning cable 3 one side is held on a corresponding post and thus independent of the wall of a gym, for example is, so that a passage between the post and the wall is guaranteed for the players. ;

The post consists of the actual post 4, the is inserted into a corresponding ground sleeve in the floor of the hall or the sports field and the one at its upper end Clamping post 5 carries. Both posts consist of profile elements that are non-circular in cross-section, so that Rotation of the posts against each other is not possible. The lower tensioning cable 3 is attached to the support post 4 via a tensioning sleeve 6 held, the clamping sleeve being fixed in its height position via its corresponding actuating device 7 can.

The actual tensioning post is closed at its upper end by an end plate 8 which has a pulley 9 carries, wherein the deflection roller is arranged freely rotatably in corresponding roller holders 10.

At the lower end of the clamping post 5, a U-bracket 11 is fixed welded on, which carries a cover, generally designated 12, with the cover bracket 14 being movable about the joint 15 is and can be set on the locking device 16. The cover 12 carries the actual clamping unit, which is generally designated 17 and consists of an outer tube 18 and an inner tube 19, these two Pipes can be adjusted relative to one another via a spindle drive 20, which is only indicated in the drawing, so that thereby a spindle telescope is created. The inner tube carries at its lower end a hook 21 into which the upper Tensioning rope can be hung after bypassing the pulley 9, with the upper tensioning rope through the free Space of the U-bracket leads.

It can be seen that the height adjustment of the actual spindle telescope is independent of the arrangement of the cover from the height of the clamping post is possible.

The ones required to fix the tensioning post on the support post 4 Fixing means are not shown in the drawing for reasons of clarity. For a professional they are can be used without difficulty.

To adjust the actual rope 1, the tensioning unit is set to the desired height, so that a certain slight pre-tensioning of the upper tensioning cable is achieved after the tensioning post has been adjusted to the correct height.

After hanging the upper tensioning cable 2 can now through Pressing the spindle 20 the desired tension of the oharen rope can be achieved / by / that the inner tube 19 according to is moved below and thereby pulls the tensioning rope over the guide pulley and tensions the rope. The definition of the lower tension cable 3 is done in the simplest way by hand by actuating the: clamping sleeve 6.

The use of the clamping post, which is closed at its upper end 5 also has the advantage that rain or other contamination when the system is used outside does not enter the SpiJinpost or the support post can penetrate.

From the drawing it can also be seen / that the lower end of the inner tube 19 extends over support elements on the outside of the stand post 4, only the support element 22 facing the viewer can be seen in the drawing.
