The enlarged trunnion segment increases the load capacity if the scissor jack without a significant size or weight increase.

Abstract: The present invention is a multiple pump transmission jack for use with removing and repairing transmissions. The jack has two hydraulic pumps mounted on a base which are connected with interrelated oil passages or conduits formed within the base, which is operated by a pedal connected with the two pumps for drawing hydraulic oil from a reservoir and into an oil pressure cylinder to easily and quickly raise a piston rod within the oil pressure cylinder saving the operator's effort and increasing the efficiency of operation. The jack also includes an overload system that prevents the operator from placing a load on the jack which is greater than its rated load, thus preventing danger.

Abstract: A quick-to-the-ground integrated vehicle leveling and stabilizing apparatus which may be easily and accurately connected to the underside of a vehicle and which may be extended to an operative position and retracted to a storage position with a minimum of operator time and effort. The components of the present invention are self-aligning so that upon being extended to the operative position, the components are automatically properly positioned for the subsequent leveling and stabilizing operations. The apparatus has integral components that need not be separated from the leveling and stabilizing apparatus itself when the apparatus is retracted to a storage position. Furthermore, the apparatus has increased strength and durability relative to known devices.

The drive mechanisms' extruded nature enables relatively simple installation and removal as well as cost efficient maintenance thereof.

Abstract: An improved stabilizer jack for securement to the underside of a recreational vehicle. The jack includes a channel frame formed with downwardly and inwardly turned sidewalls terminating in spaced apart retaining edges forming a track. A hanger bracket is mounted to the frame having a pair of laterally opposite projecting axle tabs and a screw is rotatably mounted to the bracket and restrained against longitudinal movement. A trunnion plate is carried in the track and includes a threaded bore for engaging the screw. A support leg projects downwardly and outwardly from the track and has one end thereof pivotally carried from the trunnion plate, the medial portion of the support leg being pivotally connected to one end of a strut. The opposite end of the strut is formed with upwardly turned retainer flanges spaced laterally apart, the flanges each including an axle tab bore.

Abstract: An improved gladhand security lock apparatus is locked to a gladhand brake line coupler to immobilize a trailer. The body of the security lock apparatus is formed with an abutment surface from which depends a clevis wall and a retainer turned back from the clevis wall and spaced from the abutment surface forming a tongue receiving bight. A guard plate is formed on an end of the body and a clip with an upturned rail member is formed parallel to the guard plate and spaced therefrom. The security lock apparatus is attached to the gladhand coupler so that a tongue of the gladhand is received in the tongue receiving bight, the abutment surface of the security lock apparatus overlies a port of the gladhand coupler, and a retainer flange formed on the gladhand coupler is received between the guard plate and the clip. The security lock apparatus body comprises a barrel. A lock housing is formed in a bore in the barrel perpendicular to and confronting a keeper bolt positioned in a keeper bolt receiving bore.

Abstract: A lifting and tilting device for facilitating removal, repair and re-installation of large commercial and recreational vehicle wheels comprising a frame supported by wheels, a fork supporting tines, and a hydraulic jack interposed between the frame and the fork. The fork, in addition, includes a kicker. As one actuates the jack, the fork is vertically raised from a wheel receiving position to a predetermined height. Once the fork reaches this predetermined height, the kicker, upon further actuation of the jack, operates to tilt the fork and tines upwardly and outwardly to move the wheel carried thereon into an inclined work position.

Abstract: A quick release pedestal seat mount to support a passenger seat from the floor of a recreational vehicle includes a base plate for mounting on the floor of the recreational vehicle and a seat mounting box to which a seat may be attached. The seat mounting box may be quickly secured to the base plate by means of a set of hold down cleats which fit engagingly into a complimentary set of hold down openings in the base plate. The seat mounting box is further locked in place by means of a pair of dogs attached to a kick release handle and received into a pair of locking slots in the base plates. A simple tug on the kick release handle disengages the dogs from the locking slots and pulls the seat mounting box rearward, disengaging the hold down cleats. The seat mounting box is further formed so that it will deform under the impact of a frontal collision in such a manner as to cushion the impact of the collision to the seat occupant.

Abstract: A recreational vehicle with a floor support design that integrates two pair of jack assemblies into the undercarriage frame. The jack mounting housing is a load bearing frame member to which the jack assemblies are mounted. The jacks in one embodiment are placed in a diagonal direction to the longitudinal centerline of the vehicle at the four corners of the carriage floor. The jack assembly incorporates a channel shaped leg and linkage arrangement which internest upon retraction in covering relation under a jack screw.

Abstract: A trailer stabilizer incorporating an elongated housing rigidly secured on its rear end to a trailer tongue and projecting forwardly coextensive with a friction strap disposed in overlying relationship with respect thereto. Mounted on the interior of the forward extremity of such housing and strap are a pair of friction pads. Sandwiched between such pads is the rear extremity of an elongated friction bar projecting rearwardly from a mount on the towing vehicle trailer hitch. A tensioning control device is mounted on the forward extremity of the housing in overlying relationship with respect to the strap and includes a pusher contacting such strap along its longitudinal center line to urge it toward the opposed wall of the housing to thereby maintain a uniform compressive force on the friction pads. An adjustment screw is provided for periodically adjusting the compressive force maintained by such tensioning control device.

Abstract: A multi-purpose structure for vehicles of the nature of house trailers makes use of a pair of telescoping beams which serve in part as a cross-member or beam beneath the floor of the trailer and also in part as guideways for trunnions which are attached to upper ends of the ground-engaging legs, the legs being those which serve as stabilizers when the vehicle is parked. The same telescoping beams additionally serve as housings for jack screw drives which are used to move the stabilizing legs between ground-engaging and stowed positions.
