Description

Net holder and table tennis net set with net holder

The invention relates to a net holder for a table tennis net set for a table tennis net set with a

Basic support on which a net post is arranged and / or formed, and a clamping device with which the

Base carrier can be attached to a table tennis table.

Previously known net holders have screw clamps to attach them to a table tennis table. Per se

These net holders work well, but they can come loose and slip when playing table tennis. Depending on how stable the net holders are and how strong they are

If screw clamps are tightened, the net holders can also deform. It was also observed that especially weaker people, such as children, often

Have difficulty getting a particularly tight fit

Detach the net holder from a table tennis table. Both

When trying to remove the net holder from the table tennis table, loosening movements often result in undesired movements

Damage to the table tennis table.

The object of the invention is therefore to provide a net holder of the type mentioned at the beginning for a table tennis net set which avoids the disadvantages of previously known net holders and is more convenient to use.

To solve this problem, a net holder for a table tennis net set is first proposed, which has the means and features of the independent, on a net holder

directed claim. In order to achieve the objects, it is therefore proposed, in particular in the case of the net holder of the type mentioned at the outset, that the clamping device have a movable clamping jaw and a clamping lever mechanism with which the movable jaw from a starting position in a

Clamping position is movable.

With the help of the clamping lever mechanism, the net holder can be attached to a table tennis table with a simple lever movement. Due to the leverage of the clamping lever mechanism, it is also possible to use the net holder with little

Use sufficient force to fix it firmly on a table tennis table. Overall, the handling of the net holder is simplified in comparison to previously known net holders to be mounted with screw clamps. Even comparatively weak people, such as children, can do that

Net holder not only safe and gentle on the

Attach the table tennis table, but above all loosen it. Furthermore, it is possible for the clamping lever mechanism to predetermine a defined clamping force which can be transmitted to the movable clamping jaw. Thus can

prevent the net holder from being attached to a table tennis table with excessive force, which in turn means that damage to the table tennis table by the net holder can be avoided.

The movable clamping jaw can be connected to a clamping jaw lever of the clamping lever mechanism. The clamping jaw lever can be connected via a swivel joint and / or a force support to the base carrier of the net holder on which the net post is also arranged or formed.

In one embodiment of the net holder, the

Clamping lever mechanism on a clamping lever. On the

A user of the net holder can use the clamping lever

Actuate the clamping lever mechanism and move the movable jaw out of its starting position or open position into its

Move clamping position. The clamping lever can have a Clamping lever pivot joint and / or a power support can be connected to the base support. If the clamping lever is connected to the base support via a force support, it is possible to place the clamping lever at a certain distance from the base support

be arranged, which is usually at least in the position of use of the net holder on a table tennis table

in sections located above a top of the table tennis table.

The clamping jaw lever can be arranged between a fixed clamping jaw connected to the base support and the clamping lever. The clamping jaw lever, on which the movable clamping jaw is arranged, can thus with the aid of the clamping lever in the direction of the fixed clamping jaw, which is usually an upper side of the net holder in the position of use

Contacted table tennis table with the clamping lever, which is then arranged below the clamping jaw lever, to be delivered in the direction of the fixed clamping jaw in order to fix the net holder to the table tennis table

necessary clamping force from the movable clamping jaw via the table tennis table to the stationary clamping jaw of the

Transfer net holder.

In one embodiment of the net holder it is provided that the movable clamping jaw is pivotably mounted on the clamping jaw lever and / or is connected to it. In this way it is possible to have an angular position of the clamping jaw lever relative to the movable clamping jaw and, above all, also an angular position of the clamping jaw lever relative to a

Balance table tennis table. In this way it can be ensured that the movable clamping jaw rests against the table tennis table with as much of its entire surface as possible in its clamping position. The movable clamping jaw can be pivotably mounted, for example, on a free end of the clamping jaw lever. The clamping lever can 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 position of use on a table tennis table, the clamping lever is particularly easily accessible for the user of the net holder. In this way, the net holder can be conveniently installed and removed from the table tennis table. The side of the net holder facing away from the movable clamping jaw can be the side of the net holder on which the net post of the net holder is also arranged.

In one embodiment of the net holder, it is provided that the clamping lever mechanism comprises a toggle lever tensioner with which the movable clamping jaw can be moved into its clamping position. A toggle clamp comprises at least two articulated levers, one

allow comparatively high force-displacement translation. In this way, a particularly high clamping force can be achieved with a comparatively lower actuation force, so that the net holder can be secured particularly securely to a table tennis table with the aid of a toggle clamp.

The clamping lever mechanism can be a

Include clamping width adjustment device. Using this

The clamping width adjustment device allows the net holder to be attached to table tennis tables of different strengths or thicknesses

attach. With the aid of the clamping width adjustment device, a distance between the clamps in the clamped position can be set

movable jaw and one, for example, the aforementioned fixed jaw can be adjusted.

The clamping width adjustment device can comprise an adjusting screw. With the help of the adjusting screw, the previously mentioned distance between the clamped position the movable jaw and the fixed jaw of the net holder. It when the adjusting screw is assigned a lock nut, which can be provided with knurling, is particularly advantageous. This is how the

Fix the adjusting screw at the selected screw-in depth using the lock nut, so that the selected clamping width of the net holder is retained, even if the net holder is removed from the table tennis table and stowed away after use.

The clamping lever mechanism can comprise a clamping element which can be pressed with the clamping lever against the movable clamping jaw and / or the clamping jaw lever. The clamping element can thus be used as an intermediate and / or force transmission element between the clamping lever, which is used to actuate the

Clamping lever mechanism is adjusted, and the movable jaw or the clamping jaw lever act. When the clamping lever is actuated, the adjusting movement of the clamping lever is applied to the movable clamping jaw or the

Jaw lever transferred to the movable one

Jaw is connected.

With the help of the clamping width adjustment device, a

Angular position of the clamping element to the clamping lever and thus the previously explained clamping width of the net holder can be adjusted or changed. Here, the previously mentioned adjusting screw can, depending on its screw-in depth, the

Change the angular position of the clamping element to the clamping lever. The further the set screw is screwed in, the greater the angle between the clamping element and the clamping lever can be. With increasing angle between the clamping element and the

Clamping lever, the distance between the movable clamping jaw in the clamping position and the stationary clamping jaw of the net holder and thus a clamping width of the clamping lever mechanism can decrease. In order to allow a relative movement between the clamping element and the movable clamping jaw and / or the clamping jaw lever, it can be advantageous if the clamping element on its the movable clamping jaw and / or the

Clamping jaw lever facing free end has a sliding surface and / or is provided with a roller.

The clamping element can be pivotably mounted on the clamping jaw lever. Here, the clamping element can be pivotably mounted on the clamping jaw lever that a

Projection of a swivel joint, for example one

Pivot bearing and / or a film hinge, the clamping element lies on a horizontal sectional plane of the net holder 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 sectional plane. By choosing the positions of the swivel joints and the choice of lever lengths, a particularly good path-force transmission can be achieved, which makes the net holder easy to handle and the clamping mechanism works reliably

can favor.
