Abstract

There is disclosed an entirely new configuration for a truck for skateboards, roller skates, and the like including a baseplate adapted to be connected to the underside of a skate, an elongate beam made from a flexible material, one end of the beam being connected to the baseplate and the beam extending at an acute angle relative thereto, and an elongate axle or axle hub rigidly connected to the other end of the beam and extending perpendicular thereto. The baseplate, the beam, and the axle or axle hub are a one-piece assembly made from a plastic material. An axle may extend through the hub for receipt of conventional wheels.

Claims

1. A skate truck comprising:

an elongated beam of flexible material having a width substantially greater than the thickness thereof, said beam including;

(a) a first unitary member extending in a plane generally parallel to the bottom of a skate to which it is adapted to be attached;

(b) a second unitary member formed with one end integral with the first member and the plane of the second member extending at an acute angle to the plane of the first member, the second member having at its other end an axle or axle hub connected thereto; and

(c) the second member including an elongated section extending along the longitudinal axis of the second member, centrally thereof, and normal to the axis of the axle or axle hub, the elongated section lying in a plane at right angles to the plane of the second member thereby providing resistance to vertical deflection and a twisting axis to the second member.

3. A skate truck according to claim 1 or 2, wherein said beam is molded in one piece from a plastic material.

4. A skate truck according to claim 1 or 2, wherein said beam and said axle or axle hub are molded in one piece from a plastic material.

2. A skate truck comprising:

an elongated beam made entirely from a flexible material, one end of said beam being adapted to be rigidly anchored to a skate and said beam having a portion extending at an acute angle relative the skate, the cross-section of said beam including;

(a) a first section, the width of which being significantly greater than the thickness thereof, said first section being positioned generally transverse to the longitudinal axis of the skate when said beam is connected thereto; and

(b) a second section extending longitudinally of said beam, perpendicular to said first section, from one side thereof, and generally midway between the opposite side edges thereof, for resisting vertical deflection of said beam; and

(c) an elongated axle or axle hub rigidly connected to the other end of said beam and extending perpendicular to said first and second sections thereof, said first section of said beam supporting said axle or axle hub so as to minimize wobble thereof.

5. A skate truck according to claim 2, further comprising:

an elongated, planar baseplate on said beam and being molded in one piece with said beam.

6. A skate truck according to claim 5, further comprising:

an impact post, one end of said post being rigidly connectable to said baseplate, the body of said post extending perpendicular to said baseplate, the other end of said post terminating in a position adjacent to said axle or axle hub for providing a pivot point for rotation of said axle or axle hub, said axle or axle hub being adapted to rest on said other end of said post.

7. A skate truck according to claim 6, wherein the shape of said other end of said impact post is selected to control the ease of rotation of said axle or axle hub whereby the shape of said other end of said impact post may be selected to tailor to an individual rider the turning characteristics of said truck.

8. A skate truck comprising:

an elongated beam made from a flexible plastic material, one end of said beam being adapted to be rigidly anchored to a skate with a portion of said beam extending at an acute angle relative to the skate, the cross-section of said beam including;

(a) a first section, the width of which is significantly greater than the thickness thereof, said first section being positioned generally transverse to the longitudinal axis of the skate when said beam is connected thereto; and

(b) a second section extending longitudinally of said beam, perpendicular to said first section, from one side thereof, approximately midway between the opposite sides thereof, for resisting vertical deflection of said beam;

(c) said beam being an entirely one piece, solid member; and

(d) an elongated axle or axle hub rigidly connected to the other end of said beam and extending perpendicular to said second section thereof, said first section of said beam minimizing wobble of said axle or axle hub.

9. A skate truck according to claim 8, wherein said beam and said axle or axle hub are molded in one piece from a plastic material.

10. A skate truck according to claim 8 or 9 further comprising:

an elongated, planar baseplate at said one end of said beam and being molded in one piece with said beam.

11. A skate truck according to claim 10 further comprising:

an impact post, one end of said post being rigidly connectable to said baseplate, the body of said post extending perpendicular to said baseplate, the other end of said post terminating in a position adjacent to said axle or axle hub for providing a pivot point for rotation of said axle or axle hub, said axle or axle hub being adapted to rest on said other end of said post.

12. A skate truck according to claim 11, wherein the shape of said other end of said impact post is selected to control the ease of rotation of said axle hub whereby the shape of said other end of said impact post may be selected to tailor to an individual rider the turning characteristics of said truck.
