Height adjustable basketball board with basket

The invention relates to a basketball board with a height-adjustable basket that allows players to play basketball of different age groups and correspondingly different height. According to the MPK, such inventions in the field of sports or sports. ball games classified into the field of basketball playing equipment.

The invention is based on the problem of how to design a simple and reliable basket with a basket that can be height adjustable in the range between at least two prescribed heights, measured in the vertical direction from the ground to the hoop, and which can be mounted on various existing load-bearing structures for holding the basket with the basket on the existing basketball courts in covered halls or outdoors, while providing easy handling in order to move the basket with the basket as quickly as possible to the desired height with the least physical effort.

Basketball rules, among other things, also stipulate the height of the basket, namely the distance of the hoop from the ground in a vertical direction, which is 305 cm for adult players and 260 cm for younger and accordingly lower players. As both training and match requirements can in principle be interchanged in the use of the same pitch, it is therefore desirable to adjust the height according to current needs or. requirements.

• · · ·

The need to change the height of the bin has only been present in many countries in the last few years, so at the same time as being able to change the height, the possibility of rearranging existing equipment for this purpose is also very important, as it is significantly cheaper and faster than replacing all the equipment, and therefore users can make relatively quick decisions about it.

In the field of height-adjustable basketball tables with a basket, numerous solutions are already known in the art. Thus, e.g. in EP 0 586 810 BI a proposed basket consisting of a supporting column and a panel with a basket, i.e. a ring and a net which is secured to said pillar by a mechanism formed from two parallel levers connected to the board and the pillar. The first lever is pivotally connected to its upper ends on one side by the upper end of the pillar and on the other by the upper end of the board. The rest of the lever is pivotally connected to one end of the board with one end of it, in its central region it is pivotally mounted on the pillar in the area below the location of the first lever attachment, while the rest of the other lever is pivotally connected to the top end of the rigid support, the lower end of which is attached to the bushing by which the pillar is surrounded. By changing the position of said sleeve along the pillar, the position of said levers changes, resulting in a change in the distance of the board from the base, while keeping the board in at least approximately a vertical position. The bushing can be fixed in each position by means of a pin that can be inserted through and through one of the holes provided for this purpose on the pillar. In addition, the support can be filled with ballast, which compensates for the weight of the board with the ring, which makes it easier to move the board to a higher height. This kind of solution has some drawbacks. In such a case, the height of the adjustable basket with the basket cannot be mounted on existing frames or columns. In addition, this design of the mechanism provides the necessary rigidity in the case of loads in the vertical direction, but not in the horizontal plane. Insufficient rigidity in the horizontal plane can result in oscillation in the event of a ball or ring being hit by the ball, which can then significantly affect the objectivity of the result when throwing the basket again.

• · · ·

CA 2,325,753 further proposes a basket in which the board is attached to a pole along which it is movable due to the rotation of the screw spindle. In principle, this kind of solution is not foreseen for the rearrangement of existing baskets, as well as the stiffness in the horizontal plane. The helical spindle allows for a gradual change in the height of the basket, namely the distance of the ring from the base, whereby overcoming the height, e.g. 45 cm by twisting said spindle is a relatively lengthy and also physically strenuous task, especially considering the fact that the hoop board can be relatively heavy. While moving the board in the direction of the base, the aforementioned problem does not occur as much as when moving the board in the direction away from the base, when both the friction and the weight must be calculated when twisting the spindle.

Further, JP 2004180876A proposes a mobile basket comprising a wheel frame on which a sloping support is rotatably attached, supported by suitable support. Movement of the support with said carrier, which results in a change in the height of the basket, is done by means of an electric drive. Needless to say, this kind of solution is out of the question when processing existing bins. The whole structure requires a lot of space behind the playground and in smaller indoor gyms or gyms it is often not feasible, and the very implementation of the necessary electrical connection for powering the battery or recharging the batteries necessitates further alterations and adjustments of the existing facility for which the installation is installed.

In addition, US 2009/0048041 Al proposes a basketball board with a basket consisting of two vertical guides. One carrier is provided on each of the guides, by which the assembly of the guides and plates is fastened to the support structure available in each case, said supports being rigidly connected to each other in the area between the guides. Further, on each of the guides, two spaced guide bushings are provided, with which the rigidly connected panel with the basket is movable along said guides in the vertical direction up or down by means of twisting of the cooperating spindle due to the said two guide bushings. with a threaded bushing in the area of said crossbar, in one or the other direction, during which the torsion spring, which is mounted in the corresponding housing in the area of said crossbar, is loaded or released, allowing at least partial compensation for the weight of the board during its upward movement. Such a design allows a relatively rigid mounting of the board, so that in the case of a sufficiently rigid supporting structure, when the ball hits the ring or the board, it can prevent or at least significantly reduce the oscillations of the ring in the horizontal direction. A minor problem is the design of mounting brackets for mounting the board to the supporting structure, which require the construction of holes of a certain diameter and position on the supporting structure, which is never easy when processing existing props on existing objects. Compensation of the weight of the board by means of a torsion spring is questionable because of the very characteristic of such a spring. When the spring is in the most stressed state, the torsional torque, which compensates for the weight of the spindle by compensating the weight of the ring plate, is large enough, but then declines rapidly during the spring unwinding. Therefore, if you wanted to compensate for the weight of the entire travel of the board, it would be necessary to use an extremely long spring, which is not the least possible option on the basket. Another problem is the design of the spindle itself, which is usually a single-threaded spindle that takes a long time to overcome in order to overcome a length of 45 cm. This time could be shortened by choosing a larger helix rise, but then turning the spindle would be even more difficult and there is also a restriction arising from the angle of self-restraint, since the spindle itself would start to unwind due to the very weight of the board.

The present invention relates to a height-adjustable basketball board with a basket, consisting of a frame and a faceplate, and comprises a conventional basketball basket. The board is guided vertically along at least two properly spaced guides with the help of guide bushings in the vertical direction. In this case, the board is movable in the upward or downward direction and thus in the direction of the base or away from the base by means of a spindle assembly and the frame of the connected nut in the vertical plane, and is preferably equipped with a means for compensating the weight of the plate and a corresponding spindle load. in the area of each nut.

According to the invention, it is envisaged that each guide is connected to a vertically running support profile via a suitable mounting assembly, which is connected directly or indirectly to the available support structure via a suitable adjustment element. Furthermore, there is provided a rigidly connected crossbar between the bushes, on which one of the threaded nuts coaxially arranged above each other and with different threads is provided, while each remaining nut is rigidly connected to the frame of the board. At the same time, said nuts are provided for cooperation with two separate and different threads, namely left and right, provided with threaded areas of the screw spindle, so that each of said threaded areas of the spindle is provided for cooperation with each corresponding, or with a cross between the bushings. on the guides or on the board frame rigidly connected threaded nut.

Further, the supporting profile is designed as a C-profile, along which, in the relaxed state, the rigidly attached mounting plate of the plate, which is then movable with the respective guide, is then firmly connected to said profile in each position selected.

Further, on the one hand, guides and on the other on the panel frame, the associated weight compensator according to the invention is designed as a gas damper.
