发明名称 Cabinet lifting device
摘要 A lifting and supporting device includes elongated supports. One support has a handle attached thereto. A base section has rectilinear support arms attached thereto. The arms are arranged in parallel transverse to a longitudinal length of the base section. The base section is secured to the lower end portions of the supports. Side panels are secured to the upper end portions of the supports. A moveable section is disposed medially of the side panels. A pulley mechanism lifts the movable section in a vertical direction between raised and lowered positions. The pulley mechanism is partially disposed within the cavity and is anchored to the moveable section and the side panels. The pulley mechanism includes at least five pulleys for to decrease the applied force for lifting a cabinet on the movable section. A pressure plate is used to maintain the movable section in a static position during non-operating conditions.

主权项 1. A device for lifting and supporting a cabinet during installation thereof, said lifting and supporting device comprising: a plurality of elongated supports having lower end portions and respective upper end portions disposed substantially vertically thereabove; a base section having a plurality of rectilinear support arms, wherein said plurality of rectilinear support arms is arranged in parallel transverse to a longitudinal length of said base section, said plurality of rectilinear support arms having opposed ends spaced outwardly from said base section, said base section being secured to said lower end portions of said elongated supports such that said elongated supports are elevated above a ground surface, wherein said base section maintains said supports in a substantially stable position during operating conditions; a plurality of side panels secured to said upper end portions of said plurality of elongated supports and for defining a cavity therebetween; a moveable section having a vertically oriented longitudinal axis and being disposed substantially 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; a pressure plate secured to a rear side portion of said moveable section such that said movable section is maintained in a static position during non-operating conditions; and a plurality of fasteners adjustably abutting said pressure plate against said moveable section.
