Patent ID: 7112026

Claim:
A device for lifting and supporting a cabinet during installation thereof, said device comprising: a plurality of elongated support legs having lower end portions and respective upper end portions disposed substantially vertically thereabove; a plurality of elongated dowels directly connected to said plurality of support legs and extending substantially transversely therebetween respectively, said plurality of dowels preventing movement of said plurality of support legs and for maintaining said device at a substantially stable position during operating conditions; a plurality of side panels directly secured to said upper end portions of said plurality of support legs and for defining a cavity therebetween, each of said side panels having opposed end portions directly conjoined to an adjacent one of said side panels such that said side panels extending along an entire distance between said support legs; a moveable section having a longitudinal axis and being disposed medially of said plurality of side panels; pulley means for selectively lifting said movable section in a substantially vertical direction between raised and lowered positions, said pulley means being partially disposed within said cavity and being anchored to said moveable section and said plurality of side panels; wherein said pulley means comprises: a plurality of spaced cross-braces extending substantially parallel to the axis and having opposed end portions directly connected to select ones of said plurality of side panels; a plurality of elongated first support members having lower end portions and upper end portions respectively, said plurality of support members being oriented in a substantially vertical position; a support bracket directly connected to said upper end portions of said plurality of first support members and to said movable platform respectively; a plurality of second support members directly connected medially of said plurality of cross-braces and adjacent said plurality of first support members, said plurality of second support members defining a path through which said plurality of first support members are movable; an elongated flexible rope and a plurality of sheaves directly connected to said plurality of first and second support members respectively, each of said plurality of sheaves having a grooved rim for receiving said rope therealong for changing a direction and a point of application of a pulling force and in a predetermined combination to increase the applied force for lifting a cabinet positioned onto said movable platform; and cranking means for operably winding said rope in a predetermined direction.
