Removable trainer handle and brake for skateboard

Claim 2

The combination of a trainer handle and brake for removable attachment to a skateboard and the like, the skateboard having transversely spaced front and rear wheel sets comprising: a handle strut; a handle bar fastened to one end of said strut; clamping means secured at the other end of said strut for clamping said strut to the front end of a skateboard in upstanding relation thereto, said clamping means including an upper jaw extending substantially perpendicular to said strut, a lower jaw underlying said upper jaw, and means for moving said jaws together and apart for attaching and detaching said clamping means relative to the front end of the skateboard; a pair of transversely spaced brake shoes, means pivotally supporting said spaced brake shoes beneath the lower jaw of said clamp to overlie the front wheels of the skateboard; a lever arm connected to said brake shoes; a brake handle pivotally supported on said handle strut adjacent said handle; and

Claim 3

brake operating linkage means connecting said brake handle with said lever arm for pivoting said brake shoes against the top of said front wheel set when said brake handle is actuated from a normal position and for disengaging said brake shoes from said front wheel set when said brake handle is released, said upper and lower jaws being elongated channel members the upper jaw channel member being open in the upper direction and the lower jaw channel member being open in the downward direction, the end of said strut to which the clamping means is secured having a rigid right angle extension secured in one end of said upper jaw channel member and said brace having a base portion secured in the other end of said upper channel member from said right angle extension.

Claim 4

brake operating linkage means connecting said brake handle with said lever arm for pivoting said brake shoes against the top of said front wheel set when said brake handle is actuated from a normal position and for disengaging said brake shoes from said front wheel set when said brake handle is released, said upper and lower jaws being elongated channel members the upper jaw channel member being open in the upper direction and the lower jaw channel member being open in the downward direction, the end of said strut to which the clamping means is secured having a rigid right angle extension secured in one end of said upper jaw channel member and said brace having a base portion secured in the other end of said upper channel member from said right angle extension.

Claim 5

The combination of claim 1 whereas said handle strut is adjustable in length, said handle strut including an upper section and a lower section, said upper and lower sections having overlapping adjacent ends, and means for securing the overlapping ends of said upper and lower ends together with adjacent ends overlapping and spaced apart by different predetermined and selected distances.

Claim 6

The combination of claim 1 together with an angled brace extending between said handle strut and said upper jaw of said clamp.

Claim 7

The combination of claim 1 wherein said handle bar extends transversely across said one end of said handle strut and is secured to said strut medially between opposite ends of said handle bar.

Claim 8

The combination of a trainer handle and brake for removable attachment to a skateboard and the like, the skateboard having transversely spaced front and rear wheel sets comprising: a handle strut; a handle bar fastened to one end of said strut; clamping means secured at the other end of said strut for clamping said strut to the front end of a skateboard in upstanding relation thereto, said clamping means including an upper jaw extending substantially perpendicular to said strut, a lower jaw underlying said upper jaw, and means for moving said jaws together and apart for attaching and detaching said clamping means relative to the front end of the skateboard; a pair of transversely spaced brake shoes, means pivotally supporting said spaced brake shoes beneath the lower jaw of said clamp to overlie the front wheels of the skateboard; a lever arm connected to said brake shoes; a brake handle pivotally supported on said handle strut adjacent said handle; and brake operating linkage means connecting said brake handle with said lever arm for pivoting said brake shoes against the top of said front wheel set when said brake handle is actuated from a normal position and for disengaging said brake shoes from said front wheel set when said brake handle is released, said brake shoes being integral parts of a pair of L-shaped brake plates, the plates having overlapping adjacent ends, and means for laterally adjusting the brake plates to vary the spacing between said brake shoes.

Claim 9

The combination of a trainer handle and brake for removable attachment to a skateboard and the like, the skateboard having transversely spaced front and rear wheel sets comprising: a handle strut; a handle bar fastened to one end of said strut; clamping means secured at the other end of said strut for clamping said strut to the front end of a skateboard in upstanding relation thereto, said clamping means including an upper jaw extending substantially perpendicular to said strut, a lower jaw underlying said upper jaw, and means for moving said jaws together and apart for attaching and detaching said clamping means relative to the front end of the skateboard; a pair of transversely spaced brake shoes, means pivotally supporting said spaced brake shoes beneath the lower jaw of said clamp to overlie the front wheels of the skateboard; a lever arm connected to said brake shoes; a brake handle pivotally supported on said handle strut adjacent said handle; and brake operating linkage means connecting said brake handle with said lever arm for pivoting said brake shoes against the top of said front wheel set when said brake handle is actuated from a normal position and for disengaging said brake shoes from said front wheel set when said brake handle is released, said brake shoes being integral parts of a pair of L-shaped brake plates, the plates having overlapping adjacent ends, and means for laterally adjusting the brake plates to vary the spacing between said brake shoes.
