Description

Table Tennis Net Set Including Net Holder and Net Holder

The present invention relates to a net holder for a table tennis net set comprising a base carrier on which a net post is arranged and/or configured, and a clamping device which can be used to secure the base carrier to a table tennis table.

The net holders known so far have screw clamps for fixing to the table tennis table. These net holders work well in principle, but they can become loose or slippery during a game of table tennis. Depending on how stable the net holder is constructed and how strongly the screw clamps are tightened, the net holder can also deform. It has also been observed that particularly weak people, such as children, often have problems loosening particularly tight net holders at table tennis tables. Disengaging movement while attempting to remove the net holder from the table tennis table often causes unwanted damage.

Accordingly, it is an object of the present invention to provide a net holder of the type mentioned in the introduction to the table tennis net set, which avoids the disadvantages of the hitherto known net holder and provides a more convenient net holder to use.

To achieve this object, first proposed is a net holder for a table tennis net set having the means and features of the independent claims regarding the net holder. To that end, it is proposed, in particular in the case of a net holder of the type mentioned in the introduction, that the clamping device has a movable clamping jaw and a clamping lever mechanism which can be used to move the movable clamping jaw from the starting position to the clamping position. .

The clamping lever mechanism allows the net holder to be fixed to the table tennis table with a simple lever movement. Due to the lever action of the clamping lever mechanism, it is also possible to secure the net holder to the table tennis table in a sufficiently rigid manner with little force. Overall, the handling of the net holder is simplified compared to hitherto known net holders which are mounted using screw clamps. Even relatively weak people, such as children, can secure the net holder to the ping-pong table in a safe and gentle way, as well as especially release it. It is also possible to predefine a defined clamping force that the clamping lever mechanism can transmit to the movable clamping jaws. Therefore, it is possible to prevent the net holder from being mounted on the table tennis table with excessive force, which has the effect of preventing damage to the table tennis table by the net holder.

The movable clamping jaw may be arranged on a clamping jaw lever of the clamping lever mechanism. In this case, the clamping jaw lever can be connected to the base carrier of the net holder via a pivot joint and/or a force support, the net post being also arranged or configured on said base carrier.

In an embodiment of the net holder, the clamping lever mechanism has a clamping lever. The user of the net holder can use the clamping lever to actuate the clamping lever mechanism and move the movable clamping jaw from the starting position or the open position to the clamping position. The clamping lever may be connected to the base carrier via a clamping lever pivot joint and/or force support. When the clamping lever is connected to the base carrier via a force support, the clamping lever can be disposed at a distance from the base carrier, which is generally located at least partially above the top surface of the table tennis table in the position of use of the net holder of the table tennis table.

The clamping jaw lever may be arranged between the clamping lever and the fixed clamping jaws connected to the base carrier. The clamping jaw lever with the movable clamping jaws arranged can thus be advanced by means of the clamping lever in the direction of the fixed clamping jaws, which generally contact the top of the table tennis table in the position of use. Connecting the movable clamping jaws to the fixed clamping jaws of the net holder through the table tennis table of the net holder with a clamping lever placed under the clamping jaw lever in the direction of the fixed clamping jaws to transmit the clamping force required for fixing the net holder on the table tennis table .

In an embodiment of the net holder, a movable clamping jaw is provided to be pivotally mounted to and/or connected to the clamping jaw lever. In this way, it is possible to compensate for the angular position of the clamping jaw lever relative to the movable clamping jaw, in particular the angular position of the clamping jaw lever relative to the table tennis table. It can thus advantageously be ensured that the entire surface of the movable clamping jaw is supported against the table tennis table in the clamping position. In this case, the movable clamping jaws can for example be pivotally mounted on the free end of the clamping jaw lever.

The clamping lever may be arranged on the side of the net holder facing away from the movable clamping jaw. In this way, when the net holder is in the use position of the table tennis table, the clamping lever is particularly easily accessible to the net holder user. The net holder can thus be remounted and dismounted from the table tennis table in a convenient manner. The side of the net holder away from the movable clamping jaw may also be the side of the net holder on which the net posts of the net holder are arranged.

In an embodiment of the net holder, a clamping lever mechanism is provided to include a toggle clamp that can be used to move the movable clamping jaw into a clamping position. The toggle clamp includes at least two levers that are articulated to each other and permit a relatively high force/travel ratio. In this way, a particularly high clamping force can be achieved with a relatively small actuating force, with the result that the net holder can be secured to the table tennis table by means of the toggle clamp in a particularly safe manner.

The clamping lever mechanism may comprise a clamping width-adjusting device. This clamping width adjuster can be used to secure the net holder to ping-pong tables of various sizes or thicknesses. By means of the clamping width adjustment device, the distance between the movable clamping jaws located in the clamping position and the fixed clamping jaws, for example the fixed clamping jaws already mentioned above, can be adjusted.

The clamping width adjustment device may comprise an actuating screw. Said distance between the movable clamping jaws in the clamping position and the fixed clamping jaws of the net holder can be adjusted using an actuating screw. It is particularly advantageous if the actuating screw is assigned a lock nut, which can be provided with knurling. The actuating screw can thus be secured to a selected screw depth using a lock nut, so that the selected clamping width of the net holder does not change even if the net holder is removed from the table tennis table and stored after use. .

The clamping lever mechanism may comprise a clamping element capable of being pushed against the movable clamping jaw and/or the clamping jaw lever by means of the clamping lever. The clamping element can thus function as an intermediate element and/or a force transmission element between the movable clamping jaw or the clamping jaw lever and the clamping lever which is adapted for actuation of the clamping lever mechanism. During actuation of the clamping lever, the adjustment movement of the clamping lever is transmitted via the clamping element to the movable clamping jaws or to the clamping jaw lever connected to the movable clamping jaws.

The angular position of the clamping element relative to the clamping lever, and thus the clamping width of the net holder already mentioned above, can be adjusted or changed by means of the clamping width adjustment device. Here, the actuating screw already mentioned above can change the angular position of the clamping element relative to the clamping lever, depending on the screwing depth. The more the actuating screw is tightened, the greater the angle between the clamping element and the clamping lever can be. As the angle between the clamping element and the clamping lever increases, the distance between the movable clamping jaws in the clamping position and the fixed clamping jaws of the net holder, and thus the clamping width of the clamping lever mechanism, can be reduced.

In order to allow relative movement between the clamping element and the movable clamping jaw and/or the clamping jaw lever, the free end of the clamping element facing the movable clamping jaw and/or the clamping jaw lever has a sliding surface and/or is provided with a roller .

The clamping element is positioned between the projection of the pivot joint of the clamping element in the horizontal cross-sectional plane of the net holder, for example the pivot joint of the clamping jaw lever and the projection of the pivot joint of the clamping lever in the same horizontal cross-sectional plane. may be pivotally mounted to the As a result of the selection of the position of the pivot joint and the selection of the lever length, a particularly good travel/force ratio can be achieved, which can facilitate the simple handling of the net holder and the reliable functioning of the clamping mechanism.

The clamping element may be pivotally mounted to the clamping lever. Here, the clamping element can be pivotally mounted to the clamping lever such that, for example, the pivot joint of the pivot bearing and/or the film hinge projects in the horizontal cross-sectional plane of the clamping element. The net holder is between the pivot joint projection of the clamping jaw lever and the pivot joint projection of the clamping lever in the same horizontal cross-sectional plane. As a result of the selection of the position of the pivot joint and the selection of the lever length, a particularly good travel/force ratio can be achieved, which can facilitate the simple handling of the net holder and the reliable functioning of the clamping mechanism.

The movable clamping jaw may have an end stop for a clamping element, for example the clamping element already mentioned above. By means of this end stop, it is possible, on the one hand, to define the end position of the clamping element in the movable clamping jaw and on the other hand to deflect the force of the inclined clamping element possible in the movable clamping jaw.

A clamping lever stop may be provided on the clamping lever. Movement beyond the open position of the clamping lever can be restricted by means of a clamping lever stop. The clamping lever stop is therefore used to prevent the clamping lever from hanging loosely on the net holder when the clamping lever mechanism is open.

It may be advantageous to have a protective cover on the movable and/or stationary clamping jaws to protect the table tennis table when using the net holder. This protective cover/these protective covers may preferably consist of velour and/or rubber, for example silicone rubber.

In order to achieve the stated object, finally also proposed is a table tennis net set comprising the net holder claimed in one of the claims relating to such a net holder.

The present invention will now be described in more detail based on an exemplary embodiment, but is not limited to this exemplary embodiment. Further exemplary embodiments may emerge from combinations of features of individual or several patent claims and/or from combinations of individual or several features of exemplary embodiments.
