摘要:
The invention is a rack and chain lifting device. The purpose is to convert rotational motion to linear motion in a way that is superior to a rack and pinion device because, first, it allows for more points of contact with the rack through the use of a silent chain in place of a pinion, and, second, because it can be used in corners since the motor can be distanced from the rack by means of the silent chain. The invention comprises a silent chain with link plates that are shaped such that the teeth of the link plates are offset when the chain is straightened, allowing the profile of the silent chain to correspond with the profiles of both gears and racks. The invention also comprises a rack that can be placed in corners. Some embodiments include a system of gears, a motor, and a mounting platform.
