    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.

    摘要: The invention is a silent chain with a profile capable of corresponding with the profiles of both sprockets and racks. The purpose of the invention is to convert rotational motion to linear motion in a way that is superior to the traditional rack and pinion device by allowing for more surface area contact with the rack through the use of, rather than a pinion, a silent chain that is capable of engaging with a rack. The invented silent chain comprises link plates of a particular shape stacked in alternating rows and joined together by connecting pins in such a way as to be bendable. The link plates are shaped such that the teeth of the link plates are offset when the chain is straightened, which allows the profile of the silent chain to correspond with the profiles of both sprockets and racks.
