To locate the display unit in any desired angular position in simple manner, the housing has a convex outer surface formed on a constant radius centered on the pivotal axis and a plurality of parallel grooves are provided upon the surface and extending axially. The grooves are engageable by a free end of a leaf spring which is mounted directly to the housing.
Claims7
A telephone base comprising:
- a cover;
- a display unit pivotally mounted to the cover so as to be movable around a pivotal axis from one desired pivotal position to another, the display unit comprising a housing having a first side defining a viewing aperture and a second side having an outer convex surface formed with a series of parallel grooves which extend parallel to the pivotal axis;
- and
- leaf spring means having a planar first part and a second part resiliently flexible relative to the first part;
- and the cover comprising upper and lower cover parts which provide opposing planar surfaces, the planar first part of the leaf spring means sandwiched and held between the planar surfaces, the second part of the spring means extending from the planar surfaces and engaged with any one of the grooves corresponding to a desired pivotal position of the display unit, the grooves and the second part of the spring means shaped to permit pivotal movement of the display unit in either pivotal direction against the force of the spring means.
