Patent ID: 7946597

Claim:
A roller skate frame comprising: a pair of wheel-mounting plates corresponding to each other, having a front bottom connecting face connecting said wheel mounting plates at a front end of said wheel-mounting plates; and a shoe-mounting plate connecting said wheel mounting-plates at a rear end of said wheel-mounting plates, said front bottom connecting face and said shoe-mounting plate being spaced apart from each other, said front bottom connecting face formed by an upper bridging plate and a lower bridging plate, each of said upper and lower bridging plates are integral to a corresponding one of the wheel-mounting plates and each provided with a fastener hole, the fastener holes are aligned with one another, when the upper and lower bridging plates overlap each other, so as to allow a protrusion to extend through said fastener holes and fasten said upper and lower bridging plates to each other, said upper bridging plate has at two ends respective extending portions bended downwardly wrapping over two ends of said lower bridging plate, the upper and lower bridging plates are bended with respect to the respective wheel-mounting plates along respective bending lines that are parallel to bending lines positioned between an inner edge of the wheel-mounting plate and the shoe-mounting plate, the overlap between the upper and lower bridging plates allows a width of the front bottom connecting face formed by the overlapped upper and lower bridging plates fastened to each other to be the same as a width of the shoe-mounting plate, and the front bottom connecting face is at a different height from the shoe-mounting plate.
