Varying Force Counterweight System
US Patent:
2004026, Dec 30, 2004
Filed:
Jun 26, 2004
Appl. No.:
10/876901
Inventors:
Rex King - Houma LA, US
International Classification:
A47F005/00
US Classification:
248/648000
Abstract:
This invention relates generally to a counterweight apparatus for the purpose of counterbalancing another apparatus to provide previously unavailable typically varying magnitude of force counterweight function when coupled to a scissors lift or similar apparatus. The invention herein described effectively overcomes the problem of counterbalancing the typically varying magnitude of force from a scissors lift or similar apparatus. The unique combination of counterweight movement and changes in the relative location of the sliding support arm's slidable engaged contact point with the moment arm provides the typically varying magnitude of counterweight force to substantial counterbalance the typically varying magnitude of force from a scissors lift apparatus . Working together these novel features assure substantial continuous counterbalance (neutral equilibrium) will occur in the present invention when coupled to an apparatus with typically varying magnitude of force making it a unique and useful counterweight system.
Lift-Slide Drawbridge
US Patent:
2003022, Dec 4, 2003
Filed:
May 29, 2003
Appl. No.:
10/447408
Inventors:
Rex King - Houma LA, US
International Classification:
E01D015/00
US Classification:
014/031000
Abstract:
This invention relates generally to a drawbridge apparatus for reversibly spanning from a first base to a second base, and more particularly to a cantilever drawbridge with an initial vertical motion of the bridge deck then a sliding or horizontal-linear motion of the said bridge deck. The invention herein described effectively overcomes the problem of the adjacent first bridge approach obstructing the sliding movement of a sliding drawbridge. This is achieved by an initial vertical motion lifting the bridge deck until it effectively clears the first adjacent bridge approach thereby allowing the sliding the bridge deck to slide over said first adjacent bridge approach. A lifting mechanism and a sliding mechanism are included in the design to provide the apparatus the means to move the bridge deck vertically and horizontally.
