An impulse mechanism for a vibratory device includes an eccentrically weighted shaft that is adapted to be rotated to create vibratory forces. A fan component is mounted on the eccentrically weighted shaft. The fan component has a plurality of fan blades spaced around its periphery.

Method and apparatus for cooling the impulse mechanism of a vibratory device

The present invention provides an improved collapsible step assembly for recreational vehicles. The movable step apparatus comprises a mounting frame, at least one step mounted to the frame through a linkage assembly, and a pivot rod with a longitudinal axis of rotation. In use, the pivot rod is rotatably mounted to the frame and rotates the linkage assembly and the at least one step between an extended position and a retracted position. Rotating the pivot rod in a first direction moves the step to the extended position, and rotating the pivot rod in the opposite direction moves the step to the retracted position. The linkage assembly includes a link which is movable in the direction of the link toward extension of the step to contact a stop of the frame that reacts against a gravitational load acting on the step.

Motorized collapsible step

The present invention provides an improved collapsible step assembly for recreational vehicles. The movable step apparatus comprises a mounting frame, at least one step mounted to the frame through a linkage assembly, and a pivot assembly having a pivot rod with a longitudinal axis of rotation. In use, the pivot rod is rotatably mounted to the frame and rotates the linkage assembly and the steps between an extended position and a retracted position. Rotating the pivot rod in a first direction moves the step to the extended position, and rotating the pivot rod in the opposite direction moves the step to the retracted position. A two-part linkage is rotatably engaged between the pivot rod and the step linkage and transfers downward forces on the step when retracted and when extended to the drive unit so that the step stays in its position.
