Abstract: A tunnel-style crankshaft assembly is provided having counterweights that serve the purposes of retaining the axial motion of bearings and improving the balance of the crankshaft assembly as a result of having a structure of an increased radial profile. The counterweights can include a mass section and a bearing retaining section. When the counterweight is secured to a crank web, the mass section of the counterweight is axially spaced from a bearing assembly disposed around the web. Therefore, the mass section of the counterweight may extend radially beyond an inner race of the bearing assembly without contacting the bearing assembly's cage. The mass section of the counterweight does not extend radially beyond a radial envelope of a crankshaft support surface thereby permitting the crankshaft assembly to be slidingly inserted into the crankcase.

Abstract: A hand grip for use in controlling machinery. The grip includes a grip body and a hand rest connected to the grip body. The hand rest adjustably slides and rotates with respect the grip body grip. The hand rest includes a first locking part that is configured to engage the grip body to lock the hand rest in a locked position with respect to the grip body such that the hand rest does not slide with respect to the grip body and configured to disengage from the grip body such that the hand rest slidably moves with respect to the grip body. The hand rest includes a second locking part that, when unlocked, allows the hand rest to rotate with respect to the grip body, and that, when locked, prevents the hand rest from rotating with respect to the grip body.

Abstract: An apparatus includes a mount supporting a pedal and rotatably engaging a crank arm, a resilient member fixed to the mount, and a bracket fixed to the resilient member. The bracket selectively mechanically locks the mount in first and second positions relative to the crank arm. The first position of the mount locates the pedal in an operating position away from the crank arm, and the second position of the mount locates the pedal in a storage position along the crank arm.

Abstract: A pivot control mechanism selectively controls rotation of a pivot control shaft by an electric impulse from a solenoid, which locks the pawl into the ratchet, thereby permitting the shaft to rotate in a selected direction. When a passage direction is chosen, the cam followers move out of the home position of a lofted ratchet over the peak position to the next home position. Guiding pins controlling the axial motion of the lofted ratchet in conjunction with the compression springs secure the cam followers in the home position. A shock absorber acting on the cam is used to prevent the turnstile from over rotating with any great amount of force, softening the return of the cam followers to the home position. A micro switch, when activated, sends a signal to the control board, which through the action of the solenoid, locks the pawls into the ratchet.
