  • Patent number: 5242218
    Abstract: A unitized telescopic leg assembly (10) that is incorporated into one side of a hand carried case to allow the case to be propped upright in either an opened or closed configuration. The assembly (10) includes a U-shaped housing (22) mounted inside the briefcase and includes a pair of legs (30) which are slideably retained. A piston (54) is attached to the inside end of the legs permitting the legs to extend from the case slowly due to a slight vacuum formed inside the housing. A catch assembly consisting of a actuator (80) and contiguous rods (64) inside the housing retain the legs by the urging of the rods into a keeper (58) on each leg. When the actuator is manually depressed, the legs extend and when tilted open form a four leg stand. The legs are manually retracted and held in place by the arms interfacing with the keepers.

  • Patent number: 4815756
    Abstract: A stabilizer for all terrain vehicles which has a mounting bracket (20) attached to the undercarriage to which an outrigger spring (22) or (22a) is mounted at a forward angle. A rear spring (30) extends aft of the vehicle in similar manner. Stabilizer arms (26) and (32) are juxtapositionly attached to the springs and act as snubbers, allowing limited deflection of the springs. A folded runner section 23 or a pair of outrigger feet (28), having an upwardly tapering end are integral or attached to the outrigger springs and a cross bar (34) is fastened to the rear spring providing an extended footprint capable of holding the weight of the vehicle. The spring or springs are so located as to change the center of gravity preventing the overturning of the vehicle while yieldingly absorbing the load if an obstruction is encountered.

  • Patent number: 4694770
    Abstract: A watercraft stabilizing flotation structure comprising two hulls (23) (25) that surround the outside perimeter of a single-person ski-type powered watercraft to extend the surface area in contact with the water. A seat (36) located at the stern allows the operator to sit during operation of the craft. A removable pin (34) secures the placement of the watercraft at the bow and a pair of straps and buckles (27) hold the hulls (23) and (25) together. The hulls are hollow and watertight providing a flotation chamber for the structure. In another embodiment a set of running lights (48), (50) and (52) are provided for operation in navigable waters. The lights are wired integral with the structure and are energized either by the watercraft's ignition system or an independent battery. A mechanically operated thrust reverser (54) may also be incorporated adjacent to the back of the seat assembly (36), behind the water discharge, to allow the watercraft to reverse direction or add braking capability.

  • Patent number: 4641939
    Abstract: An automatic film threading apparatus (10) that allows roll-film (58) to be automatically threaded through a series of film developing and processing chambers (12a) located on a roll-film processor (50). The apparatus is further comprised of a powered film spool (52a) and a pinch roller (16a) disposed above the spool to form a rolling intersection. A spool and roller combination is located between the upper ports (12b) of each chamber pair. Also located above and below each chamber pair is an upper and a lower film guide (18) (56). Automatic threading is accomplished by extracting a small section of film (58) from its reel (14b) and attaching the film to one end of a threading leader assembly (15). The other end of the threading leader is then manually threaded through a first chamber pair where a threading tip (15c) engages the rolling intersection of the roller (16a) and spool (52a). From this point on, the film (58) is automatically threaded through each successive chamber (12a).
