Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The invention is explained with reference to the drawings. In the drawings:

[0030] FIG. 1 shows an embodiment with full and partial views for existing basketball baskets;

[0031] FIG. 2 shows a preferred embodiment with an insertable insert ring in a C-profile; and

[0032] FIG. 3 shows a gear mechanism for tensioning and releasing the insert ring.

DETAILED DESCRIPTION OF THE INVENTION

[0033] FIG. 1 shows a net holder for a basketball net 13 having a closed hoop 1 and a net, through which a ball that has passed through the hoop 1 is braked and directed toward the ground. This net holder is one used everywhere. Replacing the net requires a ladder because the net holder is permanently installed at a lofty height.

[0034] According to the invention, in this embodiment, an insert ring 2 which is open in one portion 4 is arranged circumferentially in the hoop 1 in that the circumference of the insert ring 2 is reduced in a manner building up a tension so that it can be inserted in the inner circumference of the hoop 1 and, when the tension is released, bears against the inner walls of the hoop 1. In order to achieve this from the ground, the open portion 4 of the insert ring 2 is angled with its ends so that two pins 5, 6 oriented in the same direction from the plane of the insert ring 2 protrude from same and are connected in turn to one another by a crosspiece 7 with a fixed and a releasable bearing for the pins 5, 6, and the circumferential change in the insert ring 2 can be achieved by a movement of the pins 5, 6 towards one another and away from one another. Now only one device is needed to move the pins accordingly and thus the insert ring 2. One such device is shown in FIG. 3.

[0035] Due to the combination of the pins 5, 6 with the crosspiece 7 and the loose and the fixed bearing of the crosspiece 7 with the pins 5, 6, the net holder has a high level of dimensional stability.

[0036] The fixing of the insert ring 2 to the hoop 1 is improved by virtue of the fact that the insert ring 2 has clamps 3 which are distributed on the circumference 20 and which, when the insert ring 2 bears against the hoop 1, partially encompass the latter.

[0037] According to a further advantageous embodiment, a snap lock 8 is arranged in the region of the releasable bearing for the pin 6 and can be latched into the crosspiece 7 by means of a tappet 11 and then blocks the releasable bearing. The snap lock 8 preferably has a tappet 11 which can be displaced longitudinally in a bushing 14 connected to the pin 6 and/or the rod portion 10 and which can be moved out of the blocking function against the force of a spring 12 and thus, on the one hand, enables the clamping connection between the hoop 1 and the insert ring 2 and, on the other hand, makes it possible to reduce the diameter of the insert ring 2.

[0038] The bushing 14 is arranged in such a way that the tappet 11 is guided past the crosspiece 7.

[0039] So that it can then engage in the crosspiece 7, the tappet 11 is double-angled at one end, the last angled portion engaging in the opening of the crosspiece 7 during the blocking of the releasable bearing.

[0040] This arrangement is advantageous in order to prevent collisions between the gear mechanism 15 and the tappet 11 in the device for attaching the insert ring 2.

[0041] The net holder according to FIG. 2 differs from that described above in that the hoop 1 has a C-shaped cross section pointing with the opening in the direction of the insert ring 2. This variant can be used in particular in new installations, since it has a number of advantages.

[0042] The complicated hooks 9 for suspending the net in conventional suspension means can be dispensed with and replaced by simple hooks. This makes the interlocking and/or frictional connection possible between the hoop 1 and the inserted insert ring 2.

[0043] Clamps 3, which are additionally to be attached, are dispensed with. There are smooth transitions between the hoop 1 and the insert ring 2.

[0044] The material requirement is reduced by almost 50%.

[0045] FIG. 2 also shows the device for attaching and removing the net holder, which is discussed in more detail in FIG. 3. The present illustration shows the connection of the net holder via the receptacles 18 for the pins 5, 6. The receptacle 18 for the pin 6 has a stop 22 at the top which acts on the tappet 11 against the spring force of the spring 12 and pushes the tappet 11 out of the blocking position for the releasable bearing. The diameter of the insert ring 2 can now be reduced by moving the receptacles 18 for the pins 5, 6 towards one another.

[0046] In both embodiments, the insert ring 2 consists of a resilient material, in particular aluminum or a fiber-reinforced plastic or steel. In these embodiments, the diameter of the insert ring is selected in each case in such a way that the increase in diameter between the hoop 1 and the inserted insert ring 2 leads to an interlocking and/or frictional connection.

[0047] FIG. 3 shows a mounting device which is placed on the pins 5, 6 by means of the receptacles 18, which has a rod 16 of sufficient length and buckling strength, at the end of which there is a gear mechanism 15 for moving the receptacles 18 and which has a Bowden cable 17 for actuating the gear mechanism 15. The Bowden cable 17 is actuated by means of a ratchet 20.

[0048] The gear mechanism 15 has a guide rail 21 for the receptacles 18 for the pins. The receptacles 18 for the pins 5, 6 are displaced in a spring-loaded manner in the guide rail 21, for which purpose a sliding block 22 is arranged for each receptacle 18 in the guide rail 21. The sliding blocks 22 are connected to the respective Bowden cables 17, wherein the two Bowden cables 17 are deflected via deflection rollers 19 arranged centrally in relation to the guide rail 21 into an almost parallel course to the rod 16. Advantageously, the two Bowden cables are then combined and can thus be tensioned as one Bowden cable 17 by the ratchet 20 in order to move the pins 5, 6 towards one another.

[0049] When the insert ring 2 has reached the optimum position, the ratchet 20 is released and the insert ring assumes its position on or in the hoop 1.

[0050] Removal of the insert ring 2 is performed in an analogous manner.
