  • Patent number: 9021975
    Abstract: A seating system for marine vessels and watercraft including a chair having a backrest and a seat bottom and a lounge extension element wherein a first end of the extension element is hingeably attached to and extends from the seat bottom and wherein a second end of the extension element is configured to be hingeably attached to a first rigid structure such as a bulkhead on a watercraft. The seating system is convertible between a forward-facing seat configuration and an aft-facing lounger configuration. In the aft-facing lounger configuration, the extension element and the seat bottom are substantially parallel to one another. In the forward-facing seat configuration, the extension element is substantially upright and at an acute angle with respect to said seat bottom.

  • Patent number: 8344231
    Abstract: This invention improves guitar pitch stability and requires no modifications to a guitar or any of its parts. It is a low profile design which pertains in particular to Fender Stratocasters or any electric guitars with a similar bridge plate and tone block design. This invention does basically two things. First, the guitar strings are rerouted giving a much softer string bend past the string saddles (similar to Gibson guitars) which significantly reduces string drag (friction) at the saddles. After “dive-bombing” downward or going upward in pitch via the tremolo arm (as with a Stratocaster), the guitar returns to its original pitch when the tremolo arm is released. Second, readjustable saddle clamps are used which hold and lock all six string saddles together in position and to the bridge plate after string height and intonation adjustments have been made.

  • Patent number: 7999171
    Abstract: A guitar pickup switching system for an electric guitar consisting of three pickups (typically in the bridge, middle, and neck positions). It uses a simple on/off switch for mode control and has two possible user preference options. The first option uses a 5-position pickup selector switch, and allows for all seven possible pickup combinations: the bridge pickup alone, the middle pickup alone, the neck pickup alone, the bridge and middle pickups together (electrically in parallel), the middle and neck pickups together, the neck and bridge pickups together, and finally the bridge, middle, and neck pickups together (all 3 pickups together). The second option has electrical wiring identical to the first, but uses a simpler 3-position pickup selector switch instead of a 5-position switch. This option does not provide for the combination of all three pickups together, but all the other six possible pickup combinations are available.

  • Patent number: 7828383
    Abstract: A rotating seating assembly for use in marine vessels. The seat assembly includes a car and track assembly with moveable sections. The sections can move about curvilinear paths which are defined by the curved track segments. A unique bearing/track linkage mechanism, interlocking the component parts, is incorporated into the novel design. In one configuration, the seating sections rotate about a circle track, a full 360 degrees. Bearing assemblies and rolling mechanisms provide smooth, quiet and efficient operation of the system.

  • Patent number: 5367977
    Abstract: A boat canopy is rapidly attached and detached to a windshield with a continuous flexible member having a flat plate joined to the inside surface of the periphery of the canopy, with a lateral riser and first and second locking segments extending from the riser. The locking segments are pushed into a continuous, upwardly and outwardly facing slot arrangement of a corresponding gripping member fixed to the upper extremity of the boat windshield. The sides of the canopy are rapidly attached and detached to a side frame of the windshield through the use of detent pins extending through lateral holes in the side frame extrusion and the ends of the canopy struts.

  • Patent number: 5215032
    Abstract: A flexible member is attached continuously to an inside surface of a boat canopy along its peripheral edge, and has a portion extending lateral to the plane of the canopy with a second portion attached to the first portion and extending lateral to that first portion. A gripping member is fixed to the upper extremity of a boat windshield and has a continuous, outwardly-facing slot extending generally parallel with the upper extremity of the windshield and dimensioned to receive the first portion of the flexible member into an internal recess also portion of the flexible member into an internal recess also dimensioned to receive the second portion. The canopy is attached to the windshield by continuously pushing the second portion of the flexible member through the slot and into the internal recess.

  • Patent number: 4544189
    Abstract: A latch release arrangement for vehicle bodies which includes drive and driven members interconnected by a flexible cable for conjoint rotation. A key operated member releases the first latch directly or actuates the drive member to release the second latch through the driven member. An actuator can also operate the drive member to release the second latch through the driven member.

  • Patent number: 4478441
    Abstract: A release arrangement for releasing the detent of a latch for an exterior vehicle body closure from the inside of the body. The release arrangement includes a manually operable pivotal handle connected by a cable to an auxiliary release lever for the detent and a pull handle also connected to the release lever by another cable. The pivotal handle is mounted to a support within the body and the pull handle is releasably stored on the support. Separate housings of a common sheath house the cables.
