"Table tennis net holder"

The innovation concerns a table tennis net holder with a quick release fastener for attachment to a table top.

In the solutions customary up to now, there is a tightening of the holder the risk of surface damage to the table and damage to the clamping device itself, as there is no force limit when Application of the clamping force is provided. Another disadvantage is that within the clamping range of 12 to 70 mm cannot be adjusted quickly enough for the respective table thickness.

The innovation is based on the task of addressing the disadvantages of the previously known To avoid solutions and to improve the embodiment explained at the beginning so that a quick and damage-free Can be tightened.

This object is achieved according to the innovation in that on one Guide of the net holder a clamping piece is guided freely displaceably, which carries a pressure plate hinged to it, which with its top with a support arm of the net holder a distance-variable

union slot for the tabletop and with its underside rests on a clamping lever of the quick release fastener which has a defined latching position and which is mounted on the clamping piece is.

The table tennis net holder is pushed onto the edge of a table top with the aforementioned slot; then it will Clamping piece pushed up from below until the pressure plate rests against the underside of the table edge. By pressing the The clamping lever is used to tighten the clamping lever, whereby the same contact pressure is always the same for each tabletop thickness due to the defined locking position results. The clamping lever remains in its defined locking position until it is actuated again from its locking position is resolved.

The clamping lever of the quick release fastener can be part of a toggle clamp or be a swivel wedge.

The guide for the clamping piece preferably has a displacement path downwardly delimiting elastically resilient stop lug.

Further features and advantages of the innovation are in the constructive Description explained.

In the. Drawings are some exemplary embodiments of the innovation. Show it:

Figure 1 shows a table tennis net holder in side view;

FIG. 2 shows the individual parts of the table tennis net holder according to FIG. 1 in a side view and partly in a top view;

FIG. 3 shows the individual parts according to FIG. 2 in plan view and partly in side view and

FIG. 4 shows a detail of a modified embodiment in FIG Side and front view.

A net holder 1 has a guide 1a on which a clamping piece 2 is guided freely displaceable. The downward displacement is limited by a pin 6 (see Figure 1) or by a elastically resilient stop lug 16 (see Figure 4).

The clamping piece 2 carries a pressure plate 5 hinged to it, which with its upper side with a support arm 1b of the net holder 1 forms a variable-spaced insertion slot 14 for a table top 15. The pressure plate 5 lies with its underside on a £ defined locking position having clamping lever 3 of a quick release f Closure, which is pivotably mounted on the clamping piece 2. | The connection between pressure plate 5 and clamping lever 3 takes place via a web 4. In a modified embodiment according to FIG clamping lever 3 and pressure plate 5 are integrally formed. Here ; the three-wedge principle is applied, while in the embodiment according to Figure 1, the force transmitted via the web 4 according to the = Toggle lever principle is reinforced. Parts 3 to 11 and 17 form a height adjustment and tensioning device for the network 13.!

In any case, both the clamping path · ^! as well as the clamping force are always constant. During the clamping process; the clamping range adjustment is automatically determined. In any case, the wear clearance is eliminated by the preload. The clamping range can be continuously adjusted. I.
