<p>The purpose of the invention is to create a basketball backboard (1) with a basket (13), which should be height adjustable within an area between at least two predetermined attitudes and which could be mounted on various existing backboard support constructions (100), while at the same time a simply and easily handling in the sense of quick adjusting each desired attitude of the backboard (1) together with the basket (13) should be enabled without any essential physical effort. According to the invention, a guide (15', 15") is foreseen, along which a backboard (1) is movable by means of each disposable bush (155', 155"), which is adapted to cooperate with each corresponding guide (15', 15"), which is via appropriate attachment member (156', 156") connected to vertically extending bearing profile (14', 14"), which is either directly or indirectly via appropriate adapter (157) connected to each disposable support construction (100), while between said bushes (155', 155") on said guides (15', 15") there is a beam (150) firmly connected therewith, on which one of two differently threaded and coaxially each above the other arranged nuts (16', 16"), namely a right-threaded one and a left-threaded one, is attached, while each residual nut (16', 16") is connected with the frame (11) of the basketball backboard (1), so that each of two threaded sections (17', 17") of a spindle (17) is adapted to cooperate with each corresponding nut (16', 16"), which is connected with the beam (150) between the bushes (155', 155") on the guides (15', 15"), or with the frame (11) of the basketball backboard (1) respectively.</p> |
