Abstract
A mounting device for a bicycle having a bottom bracket planetary gear system with a sun gear or ring gear, and a bottom bracket shell positioned at the convergence of a plurality of frame parts of a bicycle frame is disclosed herein. The mounting device preferably has a control plate, a drive side bearing flange, a control input and control pawl. The control pawl blocks the sun gear, ring gear or planet carrier of the planetary system of the bicycle transmission thereby transferring the sun gear, ring gear or planet carrier force to the control pawl then to the control plate and then to the bicycle frame.

A mounting device for a bicycle having a bottom bracket planetary gear system with a sun gear or ring gear, and a bottom bracket shell positioned at the convergence of a plurality of frame parts of a bicycle frame, the mounting device comprising:
- a control plate having a body comprising a central aperture, an annular wall, a first surface and a second surface, the annular wall having a torque fix feature for engaging one of the frame parts, the aperture extending through the body, the second surface mounted against the bottom bracket shell;
- a drive side bearing flange positioned through the central aperture of the body of the control plate and positioned through an aperture of the bottom bracket shell through a first opening of the aperture;
- a control input connected to the second surface of the body of the control plate, the control input controlled by a control cable;
- and
- a control pawl connected to the first surface of the body of the control plate;
- wherein the control pawl blocks the sun gear, ring gear or planet carrier of the planetary system of the bicycle thereby transferring the sun gear, ring gear or planet carrier force to the control pawl then to the control plate and then to the bicycle frame.
A bicycle having a bottom bracket planetary system, the bicycle comprising:
- a frame comprising a plurality of frame parts converging at a bottom bracket shell, the bottom bracket shell having an aperture with a first opening and a second opening;
- a gear comprising one of a sun gear, a planet gear or a ring gear;
- a control plate having a body comprising a central aperture, an annular wall, a first surface and a second surface, the annular wall having a torque fix feature for engaging one of the frame parts, the aperture extending through the body, the second surface mounted against the bottom bracket shell;
- a drive side bearing flange positioned through the central aperture of the body of the control plate and positioned through an aperture of the bottom bracket shell through a first opening of the aperture;
- a control input connected to the second surface of the body of the control plate, the control input controlled by a control cable;
- and
- a control pawl connected to the first surface of the body of the control plate;
- wherein the control pawl blocks the sun gear, ring gear or planet carrier of the planetary system of the bicycle thereby transferring the sun gear, ring gear or planet carrier force to the control pawl then to the control plate and then to the bicycle frame.
A method for transferring blocking torque from a bicycle sun gear to a bicycle control mechanism and then to a bicycle frame;
- the method comprising:
- blocking a gear with a control pawl of a control plate mounted on a bottom bracket shell of a bicycle frame, the gear comprising one of a sun gear, a planet gear or a ring gear;
- transferring a blocking force of the gear to the control pawl;
- transferring the blocking force from the control pawl to the control plate;
- and
- transferring the blocking force from the control plate to the bicycle frame.
