The shoe is connected and disconnected to the pedal by a simple edgewise movement, with the connection being arranged to maintain the shoe in driving relation with the pedal when pedaling force is applied. In an alternative construction, the male connecting lugs are formed on the pedal while the female receivers are formed on the shoe. | InventorApplicationNo. 06/510426 filed on 07/01/1983US Classes:74/594.5, Counterbalanced24/697.1, Plural distinct cavities or projections36/131, For riding (e.g., cycling, horse riding, etc.)74/594.6With toe or shoe clipsField of Search74/594.6With toe or shoe clipsExaminersPrimary: Dorner, Kenneth J.Attorney, Agent or FirmUS Patent References293581, 550409, 588038, 598325, 614856, 3788163, 3964343Combination means for rigidly attaching shoe to a pedal for a foot-driven crank-operated machineIssued on: 06/22/1976 Inventor: Lauterbach International ClassesA43B 5/00 (20060101)A43B 5/14 (20060101) B62M 3/00 (20060101) B62M 3/08 (20060101) |
