Abstract

A non-metallic bracket for a bicycle hydraulic component is basically provided with a non-metallic body and a force receiving member. The non-metallic body has a hydraulic hose attachment port and an internal fluid passage. The hydraulic hose attachment port has an insertion opening disposed at an exterior surface of the non-metallic body and an internal attachment bore extending from the insertion opening towards the internal fluid passage. The internal attachment bore of the hydraulic hose attachment port includes an internal screw thread portion that threadedly receives a hose fastening fitting. The force receiving member is provided to the non-metallic body so as to receive force applied to the non-metallic body in an area of the hydraulic hose attachment port caused by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body.

First claim

What is claimed is:

1. A non-metallic bracket for a bicycle hydraulic component, the non-metallic bracket comprising:
a non-metallic body having a hydraulic hose attachment port and an internal fluid passage, the hydraulic hose attachment port having an insertion opening disposed at an exterior surface of the non-metallic body and an internal attachment bore extending from the insertion opening towards the internal fluid passage, the internal attachment bore of the hydraulic hose attachment port including an internal screw thread portion that threadedly receives a hose fastening fitting; and
a force receiving member, provided to the non-metallic body, so as to receive force applied to the non-metallic body in an area of the hydraulic hose attachment port caused by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body, the force receiving member including a tubular insert disposed in the internal attachment bore of the hydraulic hose attachment port, the tubular insert having a bushing contact surface that at least partially faces in an axial direction of the internal attachment bore of the hydraulic hose attachment port; wherein the bushing contact surface limits insertion of a bushing, located adjacent the tubular insert, in a direction towards the internal fluid passage.

2. The non-metallic bracket according to claim 1 , wherein
the force receiving member is disposed within a portion of the internal attachment bore that is between the internal screw thread portion and the internal fluid passage.

3. The non-metallic bracket according to claim 1 , wherein
the bushing contact surface tapers towards a center axis of the internal attachment bore in a direction away from the insertion opening.

4. The non-metallic bracket according to claim 1 , wherein
the tubular insert is a metallic member.

5. The non-metallic bracket according to claim 1 , wherein
the internal attachment bore has a deformable seal portion configured to be deformed by the tubular insert with force produced by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body.

6. The non-metallic bracket according to claim 5 , wherein
the deformable seal portion includes a protrusion provided on the non-metallic body.

7. The non-metallic bracket according to claim 6 , wherein
the non-metallic body has a step portion between the internal attachment bore and the internal fluid passage,
the protrusion is provided on the step portion.

8. The non-metallic bracket according to claim 1 , wherein
the tubular insert has a flange portion extending radially inward towards a center axis of the internal attachment bore.

9. The non-metallic bracket according to claim 8 , wherein
the flange portion defines an inner surface that tapers towards the center axis in a direction away from the insertion opening.

10. The non-metallic bracket according to claim 9 , wherein
the tubular insert is a continuous annular member with the bushing contact surface and the inner surface being conically shaped.

11. The non-metallic bracket according to claim 1 , wherein
the force receiving member further includes a support ring disposed on a portion the exterior surface of the non-metallic body that encircles the internal attachment bore of the hydraulic hose attachment port.

12. The non-metallic bracket according to claim 1 , wherein
the non-metallic body further has a gripping portion and a handlebar receiving recess disposed at an end of the gripping portion.

13. The non-metallic bracket according to claim 12 , further comprising
a bracket cover overlying the gripping portion of the ion-metallic body.

14. The non-metallic bracket according to claim 13 , wherein
the bracket cover is made of an elastic material.

15. The non-metallic bracket according to claim 1 , wherein
the non-metallic body is made of a resin material.

16. A bicycle hydraulic actuating device including the non-metallic bracket according to claim 1 , the bicycle hydraulic actuating device further comprising
an operating member movably mounted to the non-metallic bracket; and
a piston operatively coupled to the operating member, and movably disposed in a hydraulic chamber supported by the non-metallic bracket in response to operation of the operating member.

17. The bicycle hydraulic actuating device according to claim 16 , further comprising
the hose fastening fitting including an external screw thread portion threadedly coupled to the internal screw thread portion of the non-metallic bracket, the external screw thread portion having a tapered portion tapering towards a center axis of the internal attachment bore in a direction away from the insertion opening.

18. A non-metallic bracket for a bicycle hydraulic component, the non-metallic bracket comprising:
a non-metallic body having a hydraulic hose attachment port and an internal fluid passage, the hydraulic hose attachment port having an insertion opening disposed at an exterior surface of the non-metallic body and an internal attachment bore extending from the insertion opening towards the internal fluid passage, the internal attachment bore of the hydraulic hose attachment port including an internal screw thread portion that threadedly receives a hose fastening fitting; and
a force receiving member, provided to the non-metallic body, so as to receive force applied to the non-metallic body in an area of the hydraulic hose attachment port caused by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body, the force receiving member including a support ring disposed on a portion of the exterior surface of the non-metallic body that encircles the internal attachment bore of the hydraulic hose attachment port.

19. The non-metallic bracket according to claim 18 , wherein the support ring is a metallic member.

20. The non-metallic bracket according to claim 18 , wherein the non-metallic body includes a recess on which the support ring is disposed.

21. The non-metallic bracket according to claim 18 , wherein
the support ring has an axial length that is smaller than a depth of the recess such that an axial force produced by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body is not transmitted to the non-metallic body via the support ring.
