Abstract
A cart apparatus for lifting and moving aircraft chair units is described. The cart comprises a U-shaped frame with two sets of swivel-mounted casters on the bottom of the frame for mobility. A pair of upright support tube members with angle support members at their ends extend above the frame to support the rear stretcher bar of the chair unit. The baggage bar of the chair unit is held in place by a stop at the end of each leg of the U-shaped frame. A releasable retaining device for holding the baggage bar against the stop is also provided. The cart enables a single person to easily place the chair unit on the cart and move the cart and chair unit from place to place.
Claims16
An easy lift aircraft chair unit cart apparatus comprising;
- a planar U-shaped main frame element with generally parallel leg portions and perpendicular transverse portion;
- wheel means attached to an undersurface of said planar main frame element;
- a pair of upright support tube members each attached at one end to a frame leg portion at a point about equidistant between each frame leg portion end and said transverse frame portion, said upright support tube members oriented perpendicular to and above said planar main frame element and in opposite orientation to said wheel means;
- a support member attached to each upright support tube member at an end opposite the upright support tube end attached to the frame leg portion for supporting a chair unit;
- a stop means attached to and extending beyond each of said frame leg portion ends, opposite said transverse frame portion;
- a movable retaining means movably mounted to and extending beyond each of said frame leg portion ends, opposite said transverse frame portion, said retaining means oriented in opposition to said stop means for retaining a chair unit baggage bar against said stop means;
- and
- a release means for moving said retaining means out of opposition with said stop means to release said baggage bar therefrom.
An easy lift aircraft chair unit cart apparatus comprising;
- a planar U-shaped main frame element with generally parallel leg portions and perpendicular transverse portion;
- first and second pairs of swivel-mounted casters attached to an undersurface of said planar main frame element, each caster of said first pair attached to said frame leg portion near an end opposite said transverse frame portion and each caster of said second pair attached to said frame leg portion at a point adjacent said transverse frame portion;
- a pair of upright support tube members each attached at one end to a frame leg portion at a point about equidistant between the two casters on each leg portion, said upright support tube members oriented perpendicular to and above said planar main frame element and in opposite orientation to said pairs of casters;
- a support angle member attached to each upright support tube member at an end opposite the upright support tube end attached to the frame leg portion for supporting a rear stretcher bar of a chair unit;
- a top baggage bar stop attached to and extending beyond each of said frame leg portion ends, opposite said transverse frame portion;
- a movable baggage bar hook assembly diagonally oriented with said frame leg portion and rotatably attached to both said top baggage bar stop and a release means;
- biasing means to maintain said baggage bar hook assembly in opposition with said top baggage bar stop to retain a baggage bar therebetween;
- and
- said release means rotatably attached to both said frame leg portion and said baggage bar hook assembly for moving said baggage bar hook assembly out of opposition with said top baggage bar stop to release a chair unit baggage bar therefrom.
