Skateboard with hand brake

Abstract

A skateboard with hand brake comprises a skateboard, a handle and a hand brake. A skateboard can be an ordinary skateboard or an electric motor skateboard. The handlebar has an L shape. The end of the lower part of the handle is fitted to the hanger of the front truck of the skateboard. A hand brake comprises a brake lever, a brake cable and a brake module. A brake lever is fitted to the upper part of the handle and a brake cable connects the brake lever to the brake module that is fitted underneath the deck.

Claims

1. A skateboard comprising: a deck; a handle; and a hand brake system, wherein the hand brake system comprises: a brake lever, wherein the brake lever is mounted on the handle; a cable; a brake module, wherein the brake module is mounted to an underside of the deck, wherein the brake module includes a braking element, wherein cable operatively connects the brake lever to the braking element, wherein the braking element is pivotable between an upper position and a lower position relative to the deck through activation of the brake lever, wherein the braking element contacts the ground upon which the skateboard moves to brake the skateboard when the braking element is in the lower position, wherein the brake module comprises an L-shaped bracket, wherein the bracket includes an upper portion and a lower portion, wherein the upper portion is mounted to the underside of the deck, wherein the lower portion depends downwardly from the upper portion, wherein the braking element is pivotally connected to the bracket, wherein the braking element includes first and second plates pivotally connected to each other by a hinge, wherein the first plate is mounted to the lower portion of the bracket and is fixed relative to the lower portion of the bracket, wherein the second plate is pivotable relative to the first plate between the upper position and the lower position through activation of the brake lever.

2. The skateboard of claim 1 further comprising a spring, wherein the spring is operatively connected to the braking element and the deck, wherein the spring keeps the braking element away from the ground in the upper position when the brake lever is not activated.

3. The skateboard of claim 1, wherein the second plate includes braking material, wherein the braking material comprises rubber, wherein the braking material contacts the ground upon which the skateboard moves to brake the skateboard when the second plate is in the lower position.

4. The skateboard of claim 1 further comprising a truck, wherein the truck is mounted to an underside of the skateboard, wherein the truck comprises a hanger, wherein the handle is fitted to the hanger.

5. The skateboard of claim 4, wherein the handle includes non-parallel upper and lower parts, wherein the lower part is parallel with the longitudinal axis of the deck, wherein the hanger includes opposite first and second ends, wherein the first end securely receives the lower part of the handle.

6. The skateboard of claim 5, wherein the hanger comprises a triangular piece, wherein the first end is located at a side of the hanger and the second end is located at a corner of the hanger.

7. The skateboard of claim 4, wherein the truck further comprises a plate shaped part mounted to the underside of the deck, wherein the plate shaped part is located between the hanger and the deck.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a perspective bottom view of the skateboard with a handle and brake.

(2) FIG. 2 shows an analytical view of a brake module.

(3) FIG. 3A shows a side view of the brake module when resting.

(4) FIG. 3B shows a side view of the brake module when the brake is activated and the braking element lowered causing friction against the ground.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(5) Referring to the drawings, FIG. 1 shows a handle 16 that is fitted to the hanger 12 of the truck 14 of a skateboard 10.

(6) The handle 16 is bent upwards and extends to a certain height that gives a comfortable grip to a rider.

(7) A brake lever 18 for the brake 20 is mounted on the handle 16 near the handlebar 22.

(8) A brake cable 24 connects the brake lever 18 to the brake module 26 underneath the deck 28.

(9) FIG. 2 shows parts that form a brake module 26 that comprises a metal bracket 30, a braking element 32 and a spring 34.

(10) The metal bracket 30 is an L shaped metal plate 36 with holes 38, 39, 46, 48 on both faces 40, 42.

(11) One face 40 of the metal bracket 30 has 4 or more holes 38, 39 where 1 hole 39 is used to hold the spring 34 and the rest for screws 44 that are used for fixing the bracket 30 to the deck 28.

(12) The other face 42 of the bracket 30 has 3 or more holes 46, 48 where 1 hole 48 is used to let through the brake cable 24 and the rest to let bolts 50 to fix the bracket 30 to the braking element 32.

(13) A braking element 32 comprises a hinge 52 connected two rectangular metal to two rectangular metal plates 54, 56 where one plate is a fixed plate 54 and the other one a moving plate 56.

(14) The fixed plate 54 has same number of holes 58, 59 at same positions as its counterpart face of the metal bracket 30 to let through the brake cable 24 and the fixing bolts 50.

(15) The moving plate 56 has a piece of rubber type braking material 60 attached to the end section, a hole 62 at its external end to connect to the spring 34 and a notch hook 66 that holds end part 67 of the brake cable 24.

(16) The moving plate 56 is the part that gets pulled down in a pivoting motion when the brake cable 24 is pulled and forces the rubber type braking material 60 to touch the ground creating the friction, hence braking the skateboard 10.

(17) The hole 39 at the end section of the metal bracket 30 and the one hole 62 on the moving plate 56 of the braking element 32 are connected by a spring by the spring 34 to keep the braking element 32 away from the ground when the brake 20 is not activated.

(18) FIG. 3A and FIG. 3B show how the moving plate 56 in the brake module 26 changes its position when the brake 20 is activated.

(19) Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof.

(20) Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claim.
