Abstract

There is provided a suspension for the wheels of an in-line roller skate, the suspension comprising a frame connectable to the boot of the skate, the frame having a pair of parallel spaced-apart rails extending in the longitudinal direction of the skate, a bogey for supporting at least one of the skate'"'"'s wheels, the bogey being suspended to be pivotable about a horizontal axis relative to the frame, and beams for supporting the skate'"'"'s leading and trailing wheels, pairs of the beams being pivotably connected at one of their ends to the bogey, rotatably supporting one of the wheels at the other of their ends, and being pivotably connected to respective rails of the frame member at a point intermediate the two ends of the beams.

Claims

1. A suspension for the wheels of an in-line roller skate, comprising:

a frame member connectable to a boot of the skate, said frame member having a pair of parallel, spaced apart, longitudinally extending rails;

a bogey for directly supporting thereon at least one of the skate'"'"'s wheels, the bogey being suspended to be pivotable about a horizontal axis relative to said frame member; and

beam members for supporting the skate'"'"'s leading and trailing wheels, pairs of said beam members being pivotably connected at one end thereof to said bogey, rotatably supporting one of said wheels adjacent the other end thereof and being pivotably connected to respective ones of said rails at a point intermediate said ends of said beam members.

2. The suspension of claim 1 wherein said beam members for supporting the skate'"'"'s leading wheel are respectively connected to said rails for sliding movement substantially longitudinally along said rails.

3. The suspension of claim 2 wherein said bogey is connected to said frame member to be pivotable relative thereto and to be moveable towards and away from said frame member.

4. The suspension of claim 3 wherein said bogey is connected on one side thereof to one of said rails and on the other side thereof to the other of said rails, said connection on each side comprising a pair of horizontally spaced apart pin members, each of said pin members being slidably moveable in respective substantially vertical slots in said rails whereby said bogey can both pivot and move up and down relative to said frame member.

5. The suspension of claim 4 wherein the forwardmost pin member of said pair of pin members on each side of said bogey connect said beam members that support the skate'"'"'s leading wheel to said bogey, and wherein the rearmost pin member of said pair of pin members on each side of said bogey connect said beam members that support the skate'"'"'s trailing wheel to said bogey.

6. The suspension of claim 5 wherein said bogey supports at least two wheels thereon, one of said wheels being supported forwardly of said forwardmost of said pin members and the other of said wheels being supported rearwardly of said rearmost of said pin members.

7. The suspension of claim 6 wherein said beam members supporting the skate'"'"'s leading wheel are each pivotably connected to a respective rail by a pin member, each rail having a slot formed therein for said pin member to permit said sliding movement of said beam members.

8. The suspension of claim 7 wherein said beam members supporting the skate'"'"'s trailing wheel are each pivotably connected to a respective rail by a pin member, each rail having an aperture formed therein for receiving said pin member.
