Claims4
The combination of an athletic racket having a tubular member, with a weight device for detachable affixation to such athletic racket, said device comprising:
- first and second flexible sheets, said first sheet and said second sheet each having first and second sides, said first sides comprising non-slip surfaces having a high coefficient of friction with respect to the surface of the tubular member;
- at least one weight attached to each flexible sheet;
- an elastic member distinct from the non-slip surface and integrally attached to the first and second sheets for elastically separating the sheets into two weight-bearing portions which by stretching of the elastic member may be variably spaced apart from each other so as to position the weights on substantially opposing sides of the racket while tensioning the sheets;
- and
- latch means, for removably latching the first and second sheets together into a physically closed loop around the tubular member so as to maintain the elastic tension of the sheets while frictionally securing the weights in opposing balanced positions around the racket.
