Abstract: A pedal that includes a pedal body having a clipless structure and a member. The clipless structure includes a lip at a first portion of the pedal and a cleat at a second portion of the pedal. The pedal includes a detachable shoe platform having a cleat portion securable to the lip and a clip securable to the member. The detachable shoe platform may include an adjustable toe clip having a strap, which wraps around a shoe of a rider. The strap is adjustable by an adjustable strap fastener assembly having a lever coupled to a plate secured in a housing. The lever includes a first end biased against the strap and a second end engaged by a trigger. The trigger is operable to move the lever from a closed position to an open position against the bias force, thereby releasing the strap for adjustment.

Abstract: An exercise device employing side-by-side pivotally supported moving surfaces. In one example, an exercise device employs a first pivotable treadle assembly including a first moving surface, a first foot platform extending outwardly from a side of the first treadle assembly, and a second pivotable treadle assembly including a second moving surface. In some implementations, the exercise device includes a resistance element operably coupled to at least one of the first treadle assembly or the second treadle assembly to resist movement of the at least one of the first treadle assembly or the second treadle assembly. In some implementations, the exercise device includes an adjustment mechanism for adjusting a slope of at least one of the first treadle assembly or the second treadle assembly.

Abstract: A weight stack for an exercise machine may include one or more primary and secondary load elements that are selectively joined to a weight carriage. The load elements may be supported from below by one or more support beams and positioned at spaced apart locations on the support beam when the weight carriage is located at its rest position or when the load elements are not joined to the weight carriage during an exercise. The load elements may include engagement surfaces that engage the beam either directly by contacting the beam or indirectly via a divider structure positioned between the load elements and the beam. For some load elements, the engagement surfaces define a portion of a slot in the load element. The exercise machine may further include a single guide pole that constrains the weight carriage to move substantially linearly and vertically relative to the exercise machine's support frame.

Abstract: An exercise device employing side-by-side pivotally supported moving surfaces. In one particular example, an exercise device employs a first belt deployed about a front roller and a rear roller and an adjacent second belt deployed about a front roller and a rear roller. The rear of the belts in the area of the rear rollers are pivotally secured and the front of the belts in the area of the front roller are adapted to reciprocate in an up and down motion during use. In some implementations, the moving surfaces include an interconnection structure such that a generally downward movement of one surface is coordinated with a generally upward movement of the other surface. In other implementations, the moving surfaces are operably associated with one or more resistance elements that effect the amount of force required to pivot or actuate the moving surfaces.

Abstract: An engagement interface for an exercise machine for selectively engaging a carriage with one or more resisting elements may include one or more engagement devices arranged on the carriage. An engagement device may include a reaching or first portion and a flange or second portion. An engagement feature may be positioned on the one or more resisting elements and configured for engagement by at least one of the one or more engagement devices. The engagement feature may include a body, at least one wall extending generally perpendicular to the body, a first tab extending from the at least one wall in a first direction, and a second tab extending from the at least one wall in a second direction opposite the first direction. The first and second tabs may be configured for engagement by at least a portion of an engagement device.
