ONE PERSON FURNITURE OR APPLIANCE MOVER

摘要

A simple, portable device which enables a single person to move heavy furniture or appliances up or down inclines such as stairs or ladders. The device consists of a frame to which is fastened a means with mechanical advantage for drawing in and releasing a flexible line. The free end of the flexible line is fastened to an anchor bar or other fixed point at or beyond the top of the incline. The device is placed against the load to be moved and applies a motive force near or below the centre of gravity of the load. Location of the point of application of the motive force near or below the centre of gravity of the load provides a means of continuing the application of motive force even at the time when the load is in transition from its inclined position on the incline to its horizontal position at the top of the incline, or vice versa. Location of the device on or near the load means that the flexible line does not slide over and damage the surfaces of the incline. It also allows the person operating the device to steady the load and to guide its advance. The device can also be used as a versatile source of motive force for private, business or industrial users .
