Abstract
A pointer instrument movement is disclosed including a chassis of integrally moulded plastic, a pointer shaft rotatably mounted on the chassis, a lifting member, a measured value pickup which converts changes of the measured quantity to a mechanical deflection, a measured value transducer having a rocker connected to said lifting member for converting the mechanical deflection of the measured value pickup into a rotation of the pointer shaft, the rocker being formed integrally with said chassis.
Claims15
A pointer instrument movement comprising:
- (a) a chassis of integrally moulded plastic having a planar partition with a cutout formed therein,
- (b) a lifting member, responsive to air pressure changes
- (c) a measured value pickup for converting changes of a measured quantity to a mechanical deflection of said lifting member, said measured value pickup being mounted on one side of said partition so that said lifting member faces said partition and said mechanical deflection is directed substantially perpendicularly to said partition,
- (d) a pointer shaft mounted on the other side of said partition perpendicular thereto,
- (e) a measured value transducer for converting the mechanical deflection of said measured value pickup into a rotation of said pointer shaft, and
- (f) a rocker in said cutout forming a member of said measured value transducer, one end of said rocker being mounted pivotably on said partition and about an axis parallel to said partition, the other end of said rocker being operably mounted on said lifting member such that the mechanical deflection is transmitted to said rocker, said rocker being formed of plastic integrally with said chassis and said pivot axis of said rocker being formed by an integrally moulded portion of reduced cross-section.
