Abstract

A hydraulic brake control apparatus for attaching to an open ended handlebar of a vehicle, the handlebar having a longitudinal axis. The hydraulic brake control apparatus includes a brake housing that is attachable to the handlebar, the brake housing including a first section residing outside the handlebar, and a second section sized and shaped to be received inside the handlebar.

First claim

The invention claimed is:

1. A brake control apparatus including a clamp mechanism for attaching the brake control apparatus to an open ended handlebar of a vehicle, the handlebar having an inside surface and a longitudinal axis, comprising:
a brake housing attachable to the handlebar, the brake housing including a first section residing outside the handlebar and a second section sized and shaped to be received inside an open end of the handlebar,
the clamp mechanism arranged symmetrically about the second section of the brake housing to space apart the second section from the handlebar and operating to secure the brake housing to an inside surface of the handlebar by expanding radially, the clamp mechanism including:
an adjustor, the adjustor accessible from the first section and extending through the first and second sections and being offset from said axis of the handlebar,
a plurality of mounting parts shaped and sized to move radially outwardly and secure to the inside surface of the handlebar when a clamp nut is displaced relative to the second section by the adjustor, and
one or more friction rings positioned radially outward of the mounting parts,
wherein a brake line is received by a passage in the second section of the brake housing that is oriented radially inward of the plurality of mounting parts of the clamp mechanism.

2. The apparatus of claim 1 , wherein the adjustor includes the clamp nut and a clamp screw threadably received by the clamp nut.

3. The apparatus of claim 1 , wherein the second section includes a first cone-shaped surface.

4. The apparatus of claim 3 , wherein the clamp nut includes a second cone-shaped surface shaped to cooperate with the first cone-shaped surface to act upon the mounting parts.

5. The apparatus of claim 4 , wherein the mounting parts are shaped to be displaced radially when the first and second cone-shaped surfaces are drawn together by the adjustor.

6. The apparatus of claim 1 , wherein the one or more friction rings are disposed radially outward of the mounting parts throughout an entirety of a circumference of the clamp mechanism.

7. The apparatus of claim 1 , wherein the one or more friction rings are configured to contact the inside surface of the handlebar.

8. The apparatus of claim 1 , wherein the brake line received by the passage in the second section of the brake housing comprises a fluid conduit.

9. The apparatus of claim 8 , wherein the conduit extends along the handlebar axis and radially inward of the plurality of mounting parts of the clamp mechanism wherein the conduit is in fluid communication with a radial master cylinder formed in the first section of the housing.

10. The apparatus of claim 8 , wherein the conduit extends coaxial with said axis of the handlebar.

11. The apparatus of claim 1 , wherein the housing comprises a hydraulic master cylinder.

12. The apparatus of claim 1 , further comprising a piston configured to apply pressure to fluid in the brake line.

13. The apparatus of claim 12 , further comprising a fluid reservoir in fluid communication with the piston.
