Abstract: An apparatus is provided that raises the rear of a snowmobile while it is parked for purposes of storage, repair, and/or warming up. The apparatus is attached to the snowmobile and forms an integral part that goes everywhere with the snowmobile. An integral support rack slides out of the rear bumper of the snowmobile. Once fully extended, the user can lift the rear bumper and drop the support stand down to support the rear of the snowmobile in the air, in much the same manner as a kick stand on a bicycle works. The stand also has a supporting structure that folds out to provide a multipoint support system that prevents the snowmobile from tipping over.

Abstract: A trailer landing gear drive system in which pneumatic, hydraulic and electric motors, as well as the traditional hand crank, are easily interchangeable. The landing gear jack mechanism is disposed to easily connect to any one of these drive motors. The system can utilize any one of the three motor combinations without making any change to the jack itself. Each drive motor output shaft is keyed to connect to the input shaft driving the worm gear of the jack. The output shaft of each type of motor is keyed the same so that the motors are swappable with respect to the input shaft of the landing gear. The hand crank shaft is also keyed to be the same as the keyed motor output shafts. Each motor may include a flange to permit it to be secured to the landing gear. The system eliminates the gear reduction box and replaced it with a worm gear.

Abstract: Automatic and simultaneous retraction of a pair of stabilizer legs for a backhoe loader machine is beneficial for the operator (not shown). Instead of retracting the stabilizer legs by manually holding a pair of control levers continuously in a retract position, the operator (not shown) may simply move the control levers to an auto-retract position. The movement of the control levers in such a manner activates a control switch in connection with each of the control levers. The control switches, in turn, activate a timer relay that activates a solenoid detent operative with each control lever. Once the solenoid detents are in an activated state, the operator (not shown) may relinquish contact with the control levers. The solenoid detents will retain the control levers in the auto-retract position via electro-magnetic forces.

Abstract: A method and apparatus for retracting a support leg includes a telescoping inner leg member contained in an outer leg member. A spring-loaded pin engages the inner leg member. To lower the leg, the spring-loaded pin is removed allowing the inner leg member to extend to a desired position.

To raise the inner leg member, the spring-loaded pin is removed until a slidable trip member falls. The slidable trip member then blocks the spring-loaded pin from reengaging the inner leg member. The inner leg member is raised, the trip member lifted, and the inner leg member secured in a proper position for travel. The inner leg member can be raised by a cable attached to the inner leg member to allow one-handed operation of the entire system.

Abstract: Automatic and simultaneous retraction of a pair of stabilizer legs for a backhoe loader machine 10 is beneficial for the operator when operation of the backhoe loader is complete. Instead of retracting the stabilizer legs by manually holding a pair of control switches continuously in a control position, the operator may simply push an auto-up switch with a single, “one-touch” contact. Once the auto-up switch has been activated by the “one-touch” contact, a timer relay is enabled. The timer relay acts independently of the auto-up switch to control the simultaneously retraction of the stabilizer legs without any further contact to the auto-up switch. When the timer relay is enabled, it sends a signal to activate the control switches for a preselected time. The activation of the control switches actuates a pair of solenoid valves which control the movement of the stabilizer legs from any one of a plurality of extended positions to a fully retracted position within the preselected time.

Reinforcing ribs are also provided for the same purpose. Bowing is also minimized by facilitating the bending operation by cutting out material along the fold lines, to decrease the resistance to bending of the material.

Abstract: A lift assembly for an axle of the trailer of a semi-trailer or of another vehicle such as a straight truck, is mounted generally adjacent to and beneath each suspension beam of the axle/suspension systems of the trailer or other vehicle. The manner of mounting the lift assembly generally adjacent to and beneath the beam provides sufficient clearance for concurrent disposition of a dual service/parking brake chamber adjacent to and beneath the beam. The location and orientation of the axle lift assembly, relative to radial lines emanating from the pivot point of the suspension beam, facilitates the application of efficient lift forces to the beam by the lift assembly, which in turn results in less wear to an air chamber of the lift assembly. The air chamber of the lift assembly can be quickly and easily removed and reinstalled to allow for replacement of the dual brake chamber.

Abstract: My invention is a simple, detachable stabilizing system that is used to stabilize stationary recreational vehicles or trailers that would otherwise be unstable due to their non rigid suspension systems. Although such stabilizing systems are already commercially available, my invention is unique in that it maximizes the leverage applied against the supporting legs, thus increasing its load bearing and stability characteristics over those of other systems. My invention represents a further improvement over permanently affixed systems in that it is simple to affix to the frame of any recreational vehicle or trailer—no tools required—and it is easy to remove and convenient to store when not in use. Thus, my invention is not susceptible to damage from road dirt, grime and/or obstructions to movement (e.g., speed bumps or curbs), as any permanently affixed system is.
