Patent ID: 8690202

Claim:
A control mechanism comprising: a means for lifting, further comprising: a control post; a lift handle attached to a lift body frame about a lift pivot, said lift body frame extending longitudinally perpendicular from said control post; an at least one spring mechanism, wherein one end of said spring mechanism is attached to said lift body frame; an upper lift pivot attached to said lift body frame; a lower lift pivot attached to said control post; a hydraulic strut extending between said upper lift pivot and said lower lift pivot; a lift housing member, attached at an upper portion of said control post, said lift housing member further comprising a slide rail housing; a slide rail extending from a roller housing through said slide rail housing; a roller, said roller resting between a roller pin and a set pin within said roller housing; wherein said roller, said roller pin, and said set pin extend longitudinally within said roller housing, said roller circumposing said roller pin and resting upon said set pin; a set plate attached to said lift body frame proximate to a front outer surface of said roller housing; a lock pin extending longitudinally perpendicular from said set plate for engagement in a recess cavity, said recess cavity located on said front outer surface of said roller housing, and extending onto a lower surface of said roller housing; a plurality of spacing sliders, wherein removal of one or more of said spacing sliders allows said roller housing and said slide rail to move towards said lift housing member, freeing said lock pin from said recess cavity, thereby allowing rotation of said lift body frame and compression of said hydraulic strut; and wherein replacement of one or more of said spacing sliders allows said roller housing and said slide rail to move away from said lift housing member, thereby allowing rotation of said lift body frame and decompression of said hydraulic strut, further rotation of said lift body frame causing said lock pin to move into a locked position within said roller housing, wherein said lock pin rests upon said roller, and said set plate rests against said roller housing.
