Abstract
Abstract In a device for parking automobiles use is made of two platforms arranged one above the other and of devices for lifting and tilting these platforms. The latter devices include cooperating trackways, for example flanged rails, coacting with guide rollers on the platforms. The trackways are substantially rectilinear and arranged at an acute angle to one another so as to tilt the platforms during the lifting motion. The degree of inclination thereby achieved can be varied by an adjusting mechanism.
