Abstract
A drop-out mounting structure for wheel alignment is disclosed. The disclosed drop-out mounting structure for the wheel alignment according to an aspect of the present disclosure for mounting a drop-out member as a wheel mounting unit to a bicycle frame through a bolt in a state that the drop-out member may be set according to a predetermined reference position includes a wheel alignment unit provided to be in spherical contact with a bolt fastening portion of the drop-out member and the frame as a male and female type and performing wheel alignment according to deformation of the frame.
Claims19
A drop-out mounting structure mounting a drop-out member as a wheel mounting unit to a bicycle frame through a bolt in a state that the drop-out member is set according to a predetermined reference position, comprising
- a wheel alignment unit provided to be in spherical contact with a bolt fastening portion of the drop-out member and the frame as a male and female type and performing wheel alignment according to deformation of the frame,
- wherein the wheel alignment unit includes:
- a concave spherical portion formed at one bolt fastening hole edge of the drop-out member and the frame;
- and
- a convex spherical portion formed at another bolt fastening hole edge of the drop-out member and the frame and in spherical contact with the concave spherical portion.
A drop-out mounting structure mounting a drop-out member as a wheel mounting unit to a bicycle frame through a bolt in a state that the drop-out member is set according to a predetermined reference position, comprising
- a wheel alignment unit provided between bolt fastening portions of the drop-out member and the frame and performing wheel alignment according to deformation of the frame,
- wherein the wheel alignment unit includes a protrusion pattern portion of which a part is crushed by a fastening force of the drop-out member and the frame due to the bolt.
A drop-out mounting structure mounting a drop-out member as a wheel mounting unit to a bicycle frame through a bolt in a state that the drop-out member is set according to a predetermined reference position, comprising
- a wheel alignment unit provided at bolt fastening portions of the drop-out member and the frame and performing wheel alignment according to deformation of the frame,
- wherein the wheel alignment unit includes a concave spherical portion respectively formed at a bolt fastening hole edge on both side surfaces of the drop-out member and a washer installed to be in spherical contact with the concave spherical portion.
