Abstract

A sole plate has a leaf spring construction underneath to which the wheels are mounted. Check means are provided to prevent the sole plate from rubbing on the wheel rims and an easily operated positive toe catch is incorporated in the sole plate.

Claims

1. A roller skate comprising in combination a sole plate, heel engaging means at the rear end of the sole plate and adjustable toe engaging means adjacent the other end of said sole plate, a pair of longitudinally extending leaf spring members, means to secure said members intermediate the ends thereof to the underside of said sole plate, and at least one ground engaging wheel journalled for rotation on each end of said leaf spring members, said leaf spring members being bowed apart through the major portion of the length thereof and in interfacial relationship at the ends thereof, said means to secure said leaf spring members to the underside of said sole place including a substructure extending downwardly from said sole plate, the uppermost of said leaf spring members being secured to said substructure.

2. The roller skate according to claim 1 which includes means to prevent inadvertent engagement of the underside of said sole plate with the rims of said wheels when in use.

3. The roller skate according to claim 2 in which said last mentioned means includes a pair of snubbers secured to said leaf spring members and extending upwardly towards said sole plate and terminating spaced therefrom, said snubbers being situated one adjacent each end of said substructure.

4. The roller skate according to claim 2 in which said last mentioned means includes a pair of snubbers on said substructure and extending downwardly towards said leaf spring members and terminating spaced therefrom, said snubbers being situated one upon each end of said substructure and being struck out therefrom.

5. The roller skate according to claim 1 in which the ends of said leaf spring members are bifurcated, the bifurcated portions being turned at right angles to the plane of the leaf spring members and acting as bearing supports for said ground engaging wheels.

6. The roller skate according to claim 3 in which the ends of said leaf spring members are bifurcated, the bifurcated portions being turned at right angles to the plane of the leaf spring members and acting as bearing supports for said ground engaging wheels.

7. The roller skate according to claim 4 in which the ends of said leaf spring members are bifurcated, the bifurcated portions being turned at right angles to the plane of the leaf spring members and acting as bearing supports for said ground engaging wheels.

8. The roller skate according to claim 1 in which said toe engaging means includes a pair of slotted welt engaging clips, fulcrum means on said sole plate mounting said clips for inwardly and outwardly sliding movement limited by the length of the slots in said clips, a centrally located wing nut and stud assembly extending downwardly from said sole plate and a rocker bar on said stud, the ends of the rocker bar engaging said clips outboard of said fulcrum means whereby tightening said wing nut and stud assembly pivots the welt engaging ends of said clips inwardly.

9. The roller skate according to claim 1 in which said toe engaging means includes a pair of slotted welt engaging clips, fulcrum means on said sole plate mounting said clips for inwardly and outwardly sliding movement limited by the length of the slots in said clips, a centrally located wing nut and stud assembly extending downwardly from said sole plate and a rocker bar on said stud, the ends of the rocker bar engaging said clips outboard of said fulcrum means whereby tightening said wing nut and stud assembly pivots the welt engaging ends of said clips inwardly.

10. The roller skate according to claim 3 in which said toe engaging means includes a pair of slotted welt engaging clips, fulcrum means on said sole plate mounting said clips for inwardly and outwardly sliding movement limited by the length of the slots in said clips, a centrally located wing nut and stud assembly extending downwardly from said sole plate and a rocker bar on said stud, the ends of the rocker bar engaging said clips outboard of said fulcrum means whereby tightening said wing nut and stud assembly pivots the welt engaging ends of said clips inwardly.

11. The roller skate according to claim 5 in which said toe engaging means includes a pair of slotted welt engaging clips, fulcrum means on said sole plate mounting said clips for inwardly and outwardly sliding movement limited by the length of the slots in said clips, a centrally located wing nut and stud assembly extending downwardly from said sole plate and a rocker bar on said stud, the ends of the rocker bar engaging said clips outboard of said fulcrum means whereby tightening said wing nut and stud assembly pivots the welt engaging ends of said clips inwardly.
