Abstract:
A rotary motion limiting arrangement, comprising:a stationary component; a rotating component rotatable in either of opposite directions relative to said stationary component and having a lug thereon movable along a path of revolution with rotational movement of said rotating component; a pair of stops mounted on said stationary component at angularly spaced locations about said rotating component and movable between extended and retracted positions across and outside of said path of revolution of said lug; and a link interconnecting and movable with said stops such that in response to contact of said lug with one of said stops during clockwise rotational movement of said rotating component said one of said stops is moved from said extended position to said retracted position and concurrently the other of said stops is moved from said retracted position to said extended position such that said lug passes by said one stop and is halted at said other of said stops so as to establish a limit to the extent of clockwise rotational movement of said rotating component whereas in response to contact of said lug with said other stop during counterclockwise rotational movement of said rotating component said other stop is moved from said extended position to said retracted position and said one stop is moved from said retracted position to said extended position such that said lug passes by said other stop and is halted at said one stop so as to establish a limit to the counterclockwise rotational movement of said rotating component in said second direction, whereby a range of opposite limits to the rotational movement of said rotating component is provided by placement of said stops at selected ones of said angularly spaced locations about said rotating component.
