Asymmetric tennis or other racquet - has head on each side of racket's median longitudinal axis with different widths and frame having different thickness AB FR2691073A The racquet has a handle (4) which is aligned along the median longitudinal axis of the head. The axis divides the head into left and right parts (7,8). In each lateral plane perpendicular to the axis, the left part (8) is wider than the right part (7). The maximum thickness of the left side of the head (L2) is greater than the minimum thickness of the right side (L3). The maximum thickness is greater than that (L1) of the handle and the minimum thickness is less than this. The frame is thicker on the left side than on the right side. USE/ADVANTAGE - Asymmetric racket for tennis, and similar sports, favours the position of the heat at right angle to the ground.

摘要

The ski pole is a hollow metal tube (3) with a finger grip and wrist strap at the upper end to aid handling. A magnetic compass (1) is located in a cavity near the wrist strap, covered by a protective cover. The compass (2) is hinged about a vertical pivot allowing it to be rotated into view. Alternatively, the compass (2) is covered by a plastic end cap (4) which may or may not be transparent. USE/ADVANTAGE - Convenient location for occasionally used, but essential, navigation equipment for skiers.
