Abstract
A novel bicycle frameset created from a novel frame assembly and a novel fork assembly, where the components of the frame are joined together via the friction stir welding of the tubular components to partial bracket members and where the joining of the partial bracket members via friction stir welding rigidly connects the tubular components to create the frame, and where the components of the fork are joined together via friction stir welding of tubular components to a fork crown, and where the fork and frame combine form the frameset.
Claims19
A bicycle assembly comprising:
- a. a first tubular member comprising a first interface portion;
- and
- b. a first partial tube member comprising a first external interface portion and a first internal interface portion;
- wherein the first tubular member is engaged through the first external interface portion of the first partial tube member to create a first closed corner joint, and
- wherein the first interface portion of the first tubular member is friction stir welded to the first interior interface portion of the first partial tube member.
A method for constructing a bicycle assembly, the method comprising the steps of:
- a. providing a first tubular member comprising a first interface portion and a second interface portion;
- b. providing a first partial tubular member comprising a first external interface portion and a first internal interface portion;
- c. engaging the first interface portion of the first tubular member through the first external interface portion of the first partial tube member to form a closed corner joint between the first interface portion of the first tubular member and a first interior surface portion of the first partial tube member;
- and
- d. friction stir welding the first interface portion of the first tubular member to the first interior surface portion of the first partial tube member.
A bicycle assembly comprising:
- a. a first tubular member comprising a first interface portion;
- and
- b. a first structural connector member comprising a first interface portion;
- wherein the first interface portion of the first tubular member is engaged with the first interface portion of the first structural connector member to form a first closed corner joint;
- and
- wherein the first interface portion of the first tubular member is friction stir welded to the first interior interface portion of the first structural connector member.
