Abstract
A strap clamping block for swimming goggles, having a pair of guiding channels which are independent of each other and adapted to guide two sections of a strap extending in parallel to each other, respectively. The guiding channels respectively have separator surfaces curved, in the vicinity of a rear end of the clamping block, so as to separate the two sections of the strap up- and downward from each other.
Claims4
A strap clamping block for swimming goggles, the strap clamping block comprising:
- front and rear ends that are longitudinally opposed;
- transversely opposite side edges;
- opposite flanks each contoured by said front and rear ends and side edges;
- and
- a pair of strap guiding channels extending through the strap clamping block in a longitudinal direction between said opposite side edges so as to present a first separator surface facing one of said opposite side edges and a second separator surface facing another of said opposite side edges,
- said first and second separator surfaces being non-adjustably fixed in position relative to the opposite flanks and respectfully diverging away from each other progressively along a direction that extends from the front end toward the rear end of said clamping block, the first and second separator surfaces have longitudinal lengths that are longer than longitudinal lengths of the transversely opposite side edges.
