Abstract: Abstract of the Disclosure A slidable room assembly comprises a vehicle body having an opening formed in an exterior wall, and a reciprocable slideout unit or compartment disposed in the opening and slidable between a retracted position and an extended position. Sliding movement of the slideout unit is controlled by means of a drive mechanism that includes a pair of cables. A plurality of sheaves, rotatably mounted on the vehicle body about the opening, define a path for the cable or cables. The drive cables have a double Y-shape whereby each cable has four ends with an end being connected to each corner of the slideout unit. Sliding movement of the slideout unit 24 may be either motor driven or manually powered.

Abstract: A reinforcing bracket for trailer frame-member butt joints comprises a first flange adapted to be parallel to the face of the frame members, a second flange extending perpendicularly from the first flange, and a third flange extending from the second flange parallel to the first flange. The first flange includes a plurality of dimples that correspond to dimples in the frame members. Each dimple in the first flange has an aperture therein that corresponds to an aperture in the corresponding frame-member dimple. In operation, the bracket is bolted to the frame members forming the joint. The present invention also describes a trailer frame utilizing the reinforcing bracket.

Abstract: A fluid servicing apparatus with new and used fluid tanks for exchanging fluid with a serviceable vehicular subsystem having a fluid reservoir includes a control system with dielectric sensing capabilities to monitor the fluid level within the tanks and, based upon such fluid levels or relative changes thereto, regulate the flow of fluid between the vehicular subsystem and the tanks through selective operation of a fluid flow rate control device.

Abstract: A lift for lifting motorcycles, ATV's, or any similar vehicle. The lift includes a base, an upright extending from the base, a four-bar load-transferring lifting mechanism, a lifting frame adapted to engage the vehicle, and an operator for lifting and lowering the lifting frame.

Abstract: A fluid servicing apparatus including a manifold body with a fluid transfer circuit defining a plurality of pathways between a number of ports including first and second pump ports opening into a pump cavity for receiving a pump body coupled to a motor for driving the pump body to circulate fluid in the cavity and through the fluid transfer circuit to exchange fluid between the new and used fluid tanks and a vehicle subsystem fluid reservoir.

Abstract: A roof bow for a vehicle, comprising a vertical face, a curved top flange extending in a first direction, and a straight bottom flange extending in the first direction. Preferably, the roof bow is monolithic with a plurality of apertures in the vertical face that provide clearance for ductwork, wiring, etc. Additionally, the roof bow may comprise horizontally and vertically-extending indented embossments, and rolled embossments about the apertures. Side flanges may additionally extend in the first direction and attach to side walls of the vehicle via an angled connector.

Abstract: A multi-stage torsion axle that has a first stage torsion assembly positioned within a second stage torsion assembly. The first stage torsion assembly has a square first stage shaft within a first elastomeric bushing. The second stage torsion assembly has a square tubular second stage shaft within a second elastomeric bushing, the second stage shaft fitting around the first stage torsion assembly. A hollow square tubular housing fits around the second stage assembly. The resilience of the first stage torsion assembly is less than the resilience of the second stage torsion assembly. A stop mechanism directly transfers torque from the first stage shaft to the second stage shaft when the first stage has rotated more than a predetermined amount relative to the second stage shaft.

Abstract: Embodiments of a wheel locking chock apparatus are disclosed for use with recreational vehicles, travel trailers, and boat trailers having single or tandem axles. The chock apparatus functions not only to hold a trailer in position, but to also limit the rocking or rotational movement of tire and wheel combination where a recreational vehicle or travel trailer is used for camping. The chock apparatus generally comprises a pair of metal chocks, which are movably linked together by a screw driven mechanism for tightening and loosening the chocks about the tread area of a single tire or those tires that are adjacent to one another. The wheel locking chock apparatus uses a drive mechanism having a centrally located rotatable, cylindrical adjusting member that is manually assisted for extending and contracting the chock assemblies.

Abstract: A scissor jack assembly with double-lead Acme threaded screw. Through use of urethane or similar material as a braking means, the jack assembly is operable with a self locking action over a wider range of loads and especially at lower loads where an Acme loading phenomenon that results in said self locking action has previously been unattainable. Faster and smoother jack operation is made possible by employing a thrust bearing, including a plurality of roller or ball bearings, with the jack assembly. A spacing washer is also provided to retain the threaded shaft within the trunnions of the jack assembly, in order that the ends of each of the trunnions need not be machined or stamped to retain the trunnions within the jack assembly. Utilizing such a spacing washer decreases the costs involved with manufacturing the jack assembly, while increasing the ability to repair the jack assembly.
