Abstract

An adjustable clamping mechanism for a throttle control device on a handlebar of a vehicle includes a throttle lever and a clamp assembly that retains the throttle control device at a desired angular position upon said handlebar. The clamp assembly includes a body having a main section and a secondary section, the secondary section being disposed in a slot of the main section. A clamping member provides a clamping force upon the main section and secondary section. In an engaged position of the clamping member, the clamping member provides a clamping force to retain the throttle lever in a predetermined angular orientation upon said handlebar during operation of said vehicle. In a disengaged position of the clamping member, the clamping member does not provide the clamping force in order to permit the throttle lever to rotate about a longitudinal axis of said handlebar.

Claims

1. An adjustable clamping mechanism for a throttle control device on a handlebar of a vehicle, the adjustable clamping mechanism comprising:

a throttle lever that forms an adjustable arcuate angle with respect to said handlebar and is pivotally movable relative thereto, the throttle lever provided to adjust an engine speed of said vehicle; and

a clamp assembly that retains the throttle control device at a desired angular position upon said handlebar, the clamp assembly comprising;

a body including a main section and a secondary section, the main section having a slot formed therein that is adapted to accept said handlebar, the slot including a first interior surface that is formed complimentary to a first portion of a circumferential surface of said handlebar, the secondary section being disposed in the slot and removable with respect to the main section, the secondary section having a second interior surface that is formed complimentary to a second portion of the circumferential surface of the handlebar; and

a clamping member provided to exert a clamping force upon the main section and secondary section of the body, wherein, in an engaged position of the clamping member, the clamping member provides a clamping force between the main section and the secondary section and upon the handlebar sufficient to thereby retain the throttle lever in a predetermined angular orientation upon said handlebar during operation of said vehicle, and wherein, in a disengaged position of the clamping member, the clamping member does not provide the clamping force in order to permit the throttle lever to rotate about a longitudinal axis of said handlebar.

2. The adjustable clamping mechanism of claim 1, the body further comprising an extended member that protrudes away from the body in an axial direction with respect to the handlebar, the clamping member circumferentially surrounding the extended member and being removably installed thereon with respect to the body.

3. The adjustable clamping mechanism of claim 2, the extended member comprising first and second segments, the first segment extending directly outwards from the main section of the body and the second segment extending directly outwards from the secondary section of the body.

4. The adjustable clamping mechanism of claim 3, the first segment of the extended member including a first plurality of teeth formed on an outer circumferential surface thereof.

5. The adjustable clamping mechanism of claim 4, the clamping member having a second plurality of teeth formed on an inner circumferential surface thereof, the second plurality of teeth corresponding to the first plurality of teeth.

6. The adjustable clamping mechanism of claim 5, wherein the clamping member is a band clamp further comprising a first member that is separate and distinct from a second member, the first and second members being secured to one another at only a single side thereof.

7. The adjustable clamping mechanism of claim 6, the clamping member further comprising a cam lever disposed adjacent the first member, the cam lever including a cam surface that is configured to interact with an engagement surface on the first member such that:

in the engaged position of the clamping member, the cam surface interacts with the engagement surface in order to provide the clamping force, and

in the disengaged position of the clamping member, the cam surface does not interact with the engagement surface thereby not providing the clamping force.

8. The adjustable clamping mechanism of claim 7, the main section of the body further comprising a resilient arm member extending outwards in the axial direction with respect to the handlebar, the resilient arm member including a securing member at a distal end thereof, and the securing member extending in a radial direction such that, in an installed position of the clamping member, the securing member engages an outer side of the clamping member.

9. The adjustable clamping mechanism of claim 6, the first and second members being secured to one another by a nut and bolt configuration.

10. The adjustable clamping mechanism of claim 4, wherein the clamping member is a band clamp comprising a monolithic resilient clamp body including a first clamping protrusion disposed adjacent a second clamping protrusion.

11. The adjustable clamping mechanism of claim 10, the clamping member further comprising a cam lever disposed adjacent the first clamping protrusion, the cam lever including a cam surface that is configured to interact with an engagement surface on the resilient clamp body such that:

in the engaged position of the clamping member, the cam surface interacts with the engagement surface in order to provide the clamping force throughout the resilient clamp body, and

in the disengaged position of the clamping member, the cam surface does not interact with the engagement surface thereby not providing the clamping force.

12. The adjustable clamping mechanism of claim 11, the main section of the body further comprising a resilient arm member extending outwards in the axial direction with respect to the handlebar, the resilient arm member including a securing member at a distal end thereof, the securing member extending in a radial direction such that, in an installed position of the clamping member, the securing member engages an outer side of the clamping member.

13. The adjustable clamping mechanism of claim 10, the first and second clamping protrusions being secured to one another by a nut and bolt configuration.

14. The adjustable clamping mechanism of claim 1, the secondary section of the body including a securing protrusion and the main section of the body including an aperture corresponding to a shape of the securing protrusion such that the securing protrusion is slidingly received within the aperture when the secondary section is disposed within the main section.

15. The adjustable clamping mechanism of claim 1, wherein the throttle lever is movably secured to the main section of the body.

16. The adjustable clamping mechanism of claim 15, wherein the throttle lever is pivotably secured to the body at a top side and a bottom side of the main section.
