Abstract
A bicycle pedal assembly includes a cleat, a front cleat-retaining member, and a rear cleat-retaining member. The front cleat-retaining member is formed integrally with a pedal body, is generally inverted U-shaped, and includes a thin middle portion and two thick side portions, among which a limiting groove is defined under the thin middle portion. The cleat has a front end engaging portion with a wide lower portion inserted into the groove and confined between inclined limiting surfaces of the thick side portions, and a narrow upper portion abutting against an arcuate concave limiting surface of the thin middle portion. Two arcuate convex connecting surfaces connect the inclined limiting surfaces to the arcuate concave limiting surface.
Claims4
A bicycle pedal assembly comprising:
- a pedal shaft;
- a unitary pedal body including
- a shaft tube sleeved rotatably on said pedal shaft,
- a generally inverted U-shaped front cleat-retaining member disposed in front of said shaft tube and having two thick side portions and a thin middle portion that is formed between said thick side portions and that has a width smaller than that of said thick side portions along a vertical direction so as to define a limiting groove among said thin middle portion and said thick side portions, said thin middle portion being formed with an arcuate concave limiting surface that has two ends, each of said thick side portions being formed with an inclined limiting surface that extends rearwardly and outwardly and that has a front end, said front cleat-retaining member further having two arcuate convex connecting surfaces, each of which has two ends that are connected respectively to a respective one of said ends of said arcuate concave limiting surface and said front end of a respective one of said inclined limiting surfaces, and
- two aligned pivot arms extending rearwardly from said shaft tube;
- a rear retaining unit disposed between said pivot arms and including a rear cleat-retaining member mounted pivotally on said pivot arms so as to define a cleat-retaining space among said front and rear cleat-retaining members and said shaft tube;
- a unitary cleat confined within said cleat-retaining space and having a front end engaging portion that engages said front cleat-retaining member and that is retained between said front cleat-retaining member and said shaft tube, and a rear end engaging portion that engages said rear cleat-retaining member and that is retained between said rear cleat-retaining member and said shaft tube, said front end engaging portion having a wide lower portion that is inserted into said limiting groove in said front cleat-retaining member at a front end thereof and that has a top surface disposed above lower ends of said inclined limiting surfaces of said front cleat-retaining member so as to confine said wide lower portion of said cleat between said inclined limiting surfaces, and a narrow upper portion formed on an intermediate portion of said wide lower portion and that abuts against said arcuate concave limiting surface of said front cleat-retaining member at a front end thereof;
- and
- a biasing member for biasing said rear cleat-retaining member to turn frontwardly so as to clamp and fix said cleat between said rear cleat-retaining member and said pedal body, said cleat being swingable forcibly in a horizontal plane to move said narrow upper portion of said cleat over said arcuate concave limiting surface and one of said arcuate convex connecting surfaces so as to permit removal of said cleat from said front cleat-retaining member.
