Definitions

  • the 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 apparatus which can be used to fasten the base carrier to a table tennis table.
  • Hitherto known net holders have screw clamps for fastening to a table tennis table. These net holders function well in principle, but they can come loosen and slip during a game of table tennis. Depending on how stably the net holders are configured and how strongly the screw clamps are tightened, the net holders may also experience deformation. It has also been observed that in particular weaker people, for example children, often have problems releasing a particularly firmly tightened net holder from a table tennis table. During the attempts to remove the net holder from the table tennis table, releasing movements often result in undesired damage to the table tennis table.
  • a net holder for a table tennis net set having the means and features of the independent claim directed to a net holder.
  • the clamping apparatus has a movable clamping jaw and a clamping lever mechanism which can be used to move the movable clamping jaw from a starting position to a clamping position.
  • the net holder can be fixed to a table tennis table by way of a simple lever movement. Due to the lever action of the clamping lever mechanism, it is also possible to fix the net holder to a table tennis table in a sufficiently firm manner with little expenditure of force. Overall, the handling of the net holder is thus simplified in comparison to hitherto known net holders to be mounted using screw clamps. Relatively weak people, for example children, can also not only fasten the net holder to the table tennis table in a secure and gentle manner but in particular release it as well. It is also possible for the clamping lever mechanism to predefine a defined clamping force which can be transmitted to the movable clamping jaw. It is thus possible to prevent the net holder from being mounted on a table tennis table with excessive force, which in turn has the effect that damage to the table tennis table due to the net holder can be avoided.
  • the movable clamping jaw may be arranged on a clamping jaw lever of the clamping lever mechanism.
  • the clamping jaw lever may be connected to the base carrier of the net holder via a pivot joint and/or force support, the net post also being arranged or configured on said base carrier.
  • the clamping lever mechanism has a clamping lever.
  • a user of the net holder can use the clamping lever to actuate the clamping lever mechanism and move the movable clamping jaw from its starting position or open position to its clamping position.
  • the clamping lever may be connected to the base carrier via a clamping lever pivot joint and/or a force support. If the clamping lever is connected to the base carrier via a force support, it is possible for the clamping lever to be arranged at a certain distance from the base carrier, which in a use position of the net holder on a table tennis table is generally located at least partially above a top side of the table tennis table.
  • the clamping jaw lever may be arranged between a stationary clamping jaw, which is connected to the base carrier, and the clamping lever.
  • the clamping jaw lever, on which the movable clamping jaw is arranged can thus be advanced, by means of the clamping lever, in the direction of the stationary clamping jaw, which generally contacts a top side of the table tennis table in the use position of the net holder, with the clamping lever, which is then arranged below the clamping jaw lever, in the direction of the stationary clamping jaw, in order to transmit the clamping force required for the fastening of the net holder to the table tennis table from the movable clamping jaw via the table tennis table to the stationary clamping jaw of the net holder.
  • the movable clamping jaw In an embodiment of the net holder, provision is made for the movable clamping jaw to be pivotably mounted on the clamping jaw lever and/or connected thereto. In this way, it is possible to compensate an angular position of the clamping jaw lever relative to the movable clamping jaw and in particular also an angular position of the clamping jaw lever relative to a table tennis table. It can thus be ensured that preferably the entire surface of the movable clamping jaw bears against the table tennis table in its clamping position.
  • the movable clamping jaw may be pivotably mounted for example at a free end of the clamping jaw lever.
  • the clamping lever may be arranged on a side of the net holder facing away from the movable clamping jaw. In this way, when the net holder is in the use position on a table tennis table, the clamping lever is particularly readily accessible for the user of the net holder. The net holder can thus be mounted and also released from the table tennis table again in a convenient manner.
  • the side of the net holder facing away from the movable clamping jaw may be that side of the net holder on which the net post of the net holder is also arranged.
  • the clamping lever mechanism in an embodiment, provision is made for the clamping lever mechanism to comprise a toggle clamp which can be used to move the movable clamping jaw into its clamping position.
  • a toggle clamp comprises at least two levers which are connected to one another in an articulated manner and which permit a relatively high force/travel ratio. In this way, a particularly high clamping force can be achieved with a relatively smaller actuating force, with the result that the net holder can be fixed to a table tennis table in a particularly secure manner by means of a toggle clamp.
  • the clamping lever mechanism may comprise a clamping width-adjusting apparatus.
  • this clamping width-adjusting apparatus By means of this clamping width-adjusting apparatus, the net holder can be fastened to table tennis tables of differing size or thickness.
  • a distance between the movable clamping jaw, which is located in the clamping position, and a stationary clamping jaw, for example the stationary clamping jaw already mentioned above, can be adjusted.
  • the clamping width-adjusting apparatus may comprise an actuating screw.
  • the above-mentioned distance between the movable clamping jaw, which is located in the clamping position, and the stationary clamping jaw of the net holder can be adjusted by means of the actuating screw.
  • the actuating screw is assigned a locknut, which may be provided with knurling. The actuating screw can thus be fixed at the selected screwing-in depth by means of the locknut, with the result that a selected clamping width of the net holder remains unchanged even if the net holder is demounted from the table tennis table and stowed after use.
  • the clamping lever mechanism may comprise a clamping element which can be 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 force transmission element between the clamping lever, which is adjusted for actuation of the clamping lever mechanism, and the movable clamping jaw or the clamping jaw lever.
  • the adjusting movement of the clamping lever is transmitted via the clamping element to the movable clamping jaw or the clamping jaw lever which is connected to the movable clamping jaw.
  • an angular position of the clamping element with respect 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-adjusting apparatus.
  • the actuating screw already mentioned above can change the angular position of the clamping element with respect to the clamping lever.
  • the further the actuating screw is screwed in the greater the angle between the clamping element and the clamping lever can be.
  • the distance between the movable clamping jaw, which is located in the clamping position, and the stationary clamping jaw of the net holder, and thus a clamping width of the clamping lever mechanism can be reduced.
  • 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 may be pivotably mounted on the clamping jaw lever.
  • the clamping element may be pivotably mounted on the clamping jaw lever in such a way that a projection of a pivot joint, for example of a pivot bearing and/or of a film hinge, of the clamping element on a horizontal section plane of the net holder lies between a projection of a pivot joint of the clamping jaw lever and a projection of a pivot joint of the clamping lever on the same horizontal section plane.
  • the clamping element may be pivotably mounted on the clamping lever.
  • the clamping element may be pivotably mounted on the clamping lever in such a way that a projection of a pivot joint, for example of a pivot bearing and/or of a film hinge, of the clamping element on a horizontal section plane of the net holder lies between a projection of a pivot joint of the clamping jaw lever and a projection of a pivot joint of the clamping lever on the same horizontal section plane.
  • the movable clamping jaw may have an end stop for a clamping element, for example the clamping element already mentioned above.
  • a clamping element for example the clamping element already mentioned above.
  • a clamping lever stop may also be assigned to the clamping lever. A movement of the clamping lever beyond its open position can be restricted by means of the clamping lever stop. The clamping lever stop is thus used to prevent the clamping lever from hanging loosely on the net holder when the clamping lever mechanism is open.
  • the movable clamping jaw and/or the stationary clamping jaw has/have a protective covering.
  • This protective covering/these protective coverings can preferably be composed of velour and/or of rubber, for example silicone rubber.
