Abstract

An assembly of two sets of universal mounts for interlocking with stock handlebar clamps to secure a larger diameter handlebar to a motorcycle or comparable vehicles. The two sets of universal mounts are used for mounting larger diameter handlebars to motorcycles or comparable vehicles. The two sets of the universal mounts are interlocked with the stock handlebar clamps. Each set of the universal mount has an upper mount and a lower mount. Each mount has a semi-cylindrical groove, where the larger diameter handlebar is fitted between the semi-cylindrical grooves of the upper and lower mounts respectively. Each lower mount has a protruding arch which is respectively positioned within the respective stock handlebar clamp, and thereby interlocks with the respective stock handlebar clamp.

Claims

1. An apparatus for mounting a handlebar on stock handlebar clamps of a vehicle, the apparatus comprising

a) an elongated lower mount having a proximal side, a distal side, first and second pairs of interior bores located adjacent to one end of the lower mount and extending through from the proximal side to the distal side, third and fourth pairs of interior bores located adjacent to the other end of the lower mount, and a semi-cylindrical groove extending in the lengthwise direction and located on the proximal side, the first and third pairs of interior bores each having a countersunk cavity located on the proximal side of the lower mount, and the second and fourth pairs of interior bores each having internal threads;

b) a pair of opposite protruding arch shaped portions integrally formed on said distal side of said lower mount and located between said first and third pairs of interior bores respectively;

c) a short bolt member respectively inserted through said first and third pairs of bores of said lower mount for securing said lower mount to said stock handlebar clamps;

d) an elongated upper mount having a proximal side, a distal side, a first pair of interior bores located at one end of the upper mount and extending through from the distal side to the proximal side, a second pair of interior bores located at the other end of the upper mount and extending through from the distal side to the proximal side, and a complementary semi-cylindrical groove extending in the lengthwise direction of the upper mount and located on the proximal side, the first and second pair of interior bores of the upper mount each having a countersunk cavity located on the distal side;

e) said upper mount being positioned on top of said lower mount such that said first and second pairs of interior bores of said upper mount respectively correspond with said second and fourth pairs of interior bores of said lower mount, and said complementary semi-cylindrical groove of said upper mount aligns with said semi-cylindrical groove of said lower mount and thereby forms a full cylindrical chamber for clamping said handlebar therein; and

f) an elongated bolt member respectively inserted through said first and second pairs of interior bores of said upper mount and threadedly engaged with said second and fourth pairs of interior bores of said lower mount, thereby securing said upper mount to said lower mount such that said handlebar is secured within said full cylindrical chamber.

2. The apparatus in accordance with claim 1 wherein said upper and lower mounts are constructed of metal material.

3. The apparatus in accordance with claim 1 wherein said upper and lower mounts are constructed of plastic material.

4. The apparatus in accordance with claim 1 wherein said upper and lower mounts are constructed of carbon fiber.

5. An apparatus for mounting a handlebar on clamping means of a vehicle, the apparatus comprising:

a) lower portion having a proximal side, a distal side, first and second pairs of bores located adjacent to one end of the lower portion, third and fourth pairs of bores located adjacent to the other end of the lower portion, and a groove located on the proximal side;

b) a first bolt member respectively inserted through said first and third pairs of bores of said lower portion for securing said lower portion to said clamping means;

c) an upper portion having a proximal side, a distal side, a first pair of bores located at one end of the upper portion, a second pair of bores located at the other end of the upper portion, and a complementary groove located on the proximal side;

d) said upper portion being positioned on top of said lower portion such that said first and second pairs of bores of said upper portion respectively correspond with said second and fourth pairs of bores of said lower portion and said complementary groove of said upper portion aligns with said groove of said lower portion and thereby forms a full tubular chamber for clamping said handlebar therein; and

e) a second bolt member respectively inserted through said first and second pairs of bores of said upper portion and engaged with said second and fourth pairs of bores of said lower portion, thereby securing said upper portion to said lower portion such that said handlebar is secured within said full tubular chamber.

6. The apparatus in accordance with claim 5 wherein said upper and lower portions are constructed of metal material.

7. The apparatus in accordance with claim 5 wherein said upper and lower portions are constructed of plastic material.

8. The apparatus in accordance with claim 5 wherein said upper and lower portions are constructed of carbon fiber.

9. The apparatus in accordance with claim 5 wherein said lower portion further comprises at least two opposite protruding arch shaped portions integrally formed on said distal side and located between said first and third pairs of bores.
