Abstract

In accordance with one aspect of the present invention, a pedal apparatus is provided. The pedal apparatus comprises a pedal member including a seat and an axle configured to cooperate with the seat to support the pedal member. The pedal apparatus is configured such that a rotation of the pedal member with respect to the axle causes translation of the pedal member with respect to the axle.

Claims1

Dependent claims

A pedal apparatus (250) configured to be attached to a threaded aperture of a crank shaft (62) of a drive apparatus (60), the pedal apparatus (260) comprising:

a pedal member (10) including a bore (14), and a threaded aperture (16);
and
an axle (120) extending into the bore (14) to support the pedal member (10), the axle (120) comprising a hollow interior area extending along an axis of the axle (120), a plurality of locking grooves (173) extending in a direction of the axis of the axle (120), and a cam groove (24);
a cam follower (40) including a threaded base (42) and a cam extension (44), wherein the threaded base (42) is threadedly received in the threaded aperture (16) of the pedal member (10) with the cam extension (44) being received within the cam groove (24) of the axle (120), wherein a rotation of the pedal member (10) with respect to the axle (120) causes translation of the pedal member (10) with respect to the axle (120) along the axis of the axle (120);
a mounting device (126) coupled to the axle such that the axle may be selectively shifted relative to the mounting device in the direction of the axis of the axle (120), the mounting device comprising a threaded shank including a threaded end (27) configured to be threaded into the threaded aperture of the crank shaft (62), the mounting device further including a plurality of locking tongues (172) extending in the direction of the axis of the axle (120), the mounting device (126) further including a central portion (176) extending in the direction of the axis into the hollow interior area of the axle (120) and an assembly structure (174) engaging the central portion (176) and positioned within the hollow interior area of the axle (120);
a spring (170) positioned within the hollow interior area of the axle (120), wherein the spring engages the assembly structure (174) and the axle (120) to selectively bias each of the locking tongues (172) into a selected one of each of the locking grooves (173) to selectively lock an angular position between the mounting device and the axle, wherein an angular position between the mounting device and the axle is adjustable by translating the axle (120) in the direction of the axis of the axle (120) to unlock the locking tongues (172) from the respective locking grooves (173), rotating the axle (120) to an adjusted angular position with respect to the mounting device (126), and then biasing each of the locking tongues (172) with the spring (170) into another selected one of each of the locking grooves (173) to selectively lock the mounting device (126) in the adjusted angular position relative to the axle (120);
and
a locking device (290) provided with a plurality of fasteners (292) engaging corresponding locking apertures (294) of the locking device (290) to prevent inadvertent translation of the axle (120) relative to the mounting device (126) in the direction of the axis of the axle (120) from the selected angularly locked position.
