Slotted brake for in-line roller skate

Claim 1

A roller skate and brake usable on a road surface by an operator to achieve improved braking efficiency comprising: an in-line roller skate frame carrying a plurality of wheels mounted for rotation about a plurality of parallel axles, said axles including at least front and rear axles to permit rolling movement of said frame in forward and rearward directions; means for attaching said skate frame to the operator; a brake housing member formed of substantially rigid material and including: means attaching said housing member to said skate frame; a pair of lateral side walls and a rear wall extending between said side walls; and a rigid plate extending between said side walls and said rear wall and positioned to overlie the road surface; an integral brake pad member formed of resilient material having a high coefficient of friction carried by said housing member and including first and second lateral side faces, a front face, a rear face, an upper face and a base, said base confronting the road surface so as to frictionally engage the road surface when said skate frame is pivoted about said rear axle to bring said base into contact with the road surface; slot means on one of said members and tongue means on the other of said members with said tongue means being mateably received within said slot means to cause said pad member to be retained to said housing member with said upper face of said pad member closely confronting said plate; said slot and tongue means being constructed and arranged such that during braking operation said members are urged into locking engagement with one another as a result of frictional forces generated between said pad member and the road surface, said forces urging said pad member rearwardly against said housing member to drive said tongue means into said slot means so as to increase the locking engagement between said members during braking; said pad member including a generally upright aperture extending between said upper face and said base; said housing member including an aperture in said plate positioned to communicate with said pad member aperture when said tongue means and slot means are mateably engaged; fastening means extending through said communicating apertures to retain said tongue means in said slot means; said fastening means being a screw and a nut, said screw including a shaft for receiving said nut; and wherein said plate aperture is an open ended, forwardly extending groove for slidably receiving and guiding said screw shaft when said screw shaft extends from said pad member aperture and while said tongue means slides into mating engagement with said slot means.
