Patent ID: 7823226

Claim:
A strap adjusting device for a pair of swimming goggles comprising: a buckle including first and second through-holes spaced by a partitioning wall, with each of the first and second through-holes including an outer wall facing the partitioning wall and having a pressing edge, with each of the first and second through-holes further including two opposite sidewalls perpendicular to the outer wall, with each of the two sidewalls of the first through-hole including a first receiving portion, with each of the two sidewalls of the second through-hole including a second receiving portion; first and second pressing members respectively received in the first and second through-holes, with the first pressing member separating the first through-hole into a first inner slot adjacent the partitioning wall and a first outer slot distant to the partitioning wall, with the second pressing member separating the second through-hole into a second inner slot adjacent the partitioning wall and a second outer slot distant to the partitioning wall, with each of the first and second pressing members having two ends, with the two ends of the first pressing member being slideably and rotatably received in the first receiving portions, with the two ends of the second pressing member being slideably and rotatably received in the second receiving portions, with the first and second pressing members being movable relative to the buckle to adjust a distance between each of the first and second pressing members and one of the pressing edges; and at least one resilient strap adapted to be mounted to a body of a pair of swimming goggles and including two ends, with one of the two ends of said at least one resilient strap being extended through the first inner slot and the first outer slot and wound around the first pressing member, with another end of said at least one resilient strap being extended through the second inner slot and the second outer slot and wound around the second pressing member, with said at least one resilient strap including first and second outer portions respectively adjacent the two ends of said at least one resilient strap, and with said at least one resilient strap further including first and second clamping portions adapted for clamping a head of a user wearing the pair of swimming goggles, with the first and second outer portions being pullable by a force to adjust tightness of the strap when the pair of swimming goggles is worn on the head of the user, with the force acting on the strap urging each of the first and second pressing members to move toward one of the pressing edges to tightly clamp the strap and to fix a length of the strap.
