Basketball-stand

A basketball-stand, comprising a base which pivotally carries at least two support systems which in turn pivotally carry a beam provided with means for attachment of a back-board and dunk ring, all pivotal connections having their axes parallel to one another so that a quadrangular system of links is formed by which said beam--and thereby the stand--can be moved between a lower or storage position and a higher or playing position,

• resilient means being provided, acting between a point connected to said base and a point connected to one of said support systems, such that the resilient means are tensioned and accumulate power when the stand is brought into its storage position, which power is relieved and the accumulated energy allowed to be freed when the stand is brought into its playing position,
• at least one of said support systems comprising at least one eccentric cam, fixedly connected thereto at a place such that the axis of rotation of the eccentric cam coincides with the pivot axis of that particular support system relative to said base,
• said base slidably vertically carrying rod means, the upper end of which is capable of being driven by an element which is located opposite the cam surface of said eccentric cam such that said element will be displaced by the eccentric cam surface to the extent that, during rotation of said eccentric cam, the cam radius increases from a lower to a higher radius value,
• said rod means being arranged such that, when it slides, under control of the displacement of said element, it is capable of lifting at least part of the weight of the stand from the floor.
