Abstract

The present invention generally pertains to a handlebar assembly for a bicycle. More specifically, the present invention relates to a handlebar assembly comprising a hollow body in which are routed control cables needed for breaking and gear shifting.

Claims

1. A handlebar for a bicycle provided with a fork assembly, said handlebar comprising:

a hollow body comprising

a left end,

a right end,

at least one control opening located proximal to at least one of said left end and said right end of said hollow body,

a central stem portion defining a fork mounting portion and having a left end, a right end, a plan bottom face and a plan top face extending between the left end and the right end of said central stem portion,

said fork mounting portion extending between said left end and said right end of said hollow body, and being adapted for mounting said handlebar to said fork assembly and comprising a fork opening;

a left handle shaft extending from said left end of said hollow body;

a right handle shaft extending from said right end of said hollow body;

at least one control mounted to at least one of said left handle shaft and said right handle shaft proximal to said at least one control opening such that said at least one control opening and said fork opening enable routing of at least one control cable running from said at least one control toward said fork assembly inside said hollow body, said at least one control cable remaining unexposed during operation of said at least one control;

said hollow body further comprising a left handle mounting portion having a lower end and an upper end, said left handle mounting portion extending from said left end of said central stem portion;

said hollow body further comprising a right handle mounting portion having a lower end and an upper end, said right handle mounting portion extending from said right end of said central stem portion,

wherein said left handle mounting portion, said central stem portion and said right handle mounting portion define an integral structure, and

wherein said left handle mounting portion and said right handle mounting portion are S-shaped.

2. The handlebar as claimed in claim 1, wherein said handlebar is V-shaped.

3. The handlebar as claimed in claim 2, further wherein said hollow body comprises a left control opening located proximal to said left end of said hollow body and a right control opening located proximal to said right end of said hollow body;

further wherein said at least one control comprises;

a left brake lever assembly mounted to said left handle shaft proximal to said left control opening;

a right brake lever assembly mounted to said right handle shaft proximal to said right control opening; and

a gear shifter mounted to said right handle shaft proximal to said right control opening.

4. The handlebar as claimed in claim 3, wherein said hollow body comprises a left hollow body portion and a right hollow body portion, said left handle shaft and said right handle shaft being connected to said fork mounting portion and extending through said left hollow portion and said right hollow portion.

5. The handlebar as claimed in claim 4, wherein said left handle shaft, said right handle shaft and said fork mounting portion define an integral structure.

6. The handlebar as claimed in claim 1, wherein said at least one control is selected from a group consisting of a brake lever assembly and a gear shifter.

7. The handlebar as claimed in claim 1, wherein said plan bottom face and said plan top face are connected to one another using a pair of spaced-apart back and front curved faces.

8. The handlebar as claimed in claim 1, wherein said upper end of said left handle mounting portion comprises a left opening for receiving a portion of said left brake lever assembly, further wherein said right handle mounting portion comprises a right opening for receiving a portion of said right brake lever assembly and a portion of said gear shifter.

9. The handlebar as claimed in claim 8, wherein said left opening comprises a left mounting member and said right opening comprises a right mounting member.

10. The handlebar as claimed in claim 9, wherein said left handle shaft is fixedly mounted to said left mounting member of said left opening and said right handle shaft is fixedly mounted to said right mounting member of said right opening.

11. The handlebar as claimed in claim 10, further comprising at least one handle grip mounted over at least one of said left handle shaft and said right handle shaft.

12. The handlebar as claimed in claim 11, wherein said at least one handle grip is manufactured using a material selected from a group consisting of rubber, plastic, polyvinyl chloride (PVC) and elastomer.

13. The handlebar as claimed in claim 10, wherein said left brake lever assembly comprises a left bracket mountable to said left handle shaft, a left lever mounted to said left bracket for pivotal movement relative thereto and a left brake cable connector connected to said left lever.

14. The handlebar as claimed in claim 10, wherein said right brake lever assembly comprises a right bracket mountable to said right handle shaft, a right lever mounted to said right bracket for pivotal movement relative thereto and a right brake cable connector connected to said right lever.

15. The handlebar as claimed in claim 10, wherein said gear shifter comprises a twist-grip shifter having an annular base member for mounting said gear shifter to said right handle shaft and a twist grip operating member rotatably mounted on said annular base member for enabling a user to modify a bicycle gear ratio, said gear shifter further comprising a cable connector.

16. The handlebar as claimed in claim 1, wherein said hollow body is manufactured using a material selected from a group consisting of aluminum, carbon fibers, steel, titanium and magnesium.
