US Patent:

54601185, Oct 24, 1995

Filed:

Aug 13, 1993

Appl. No.:

8/105941

Inventors:

Timothy S. Shea - Morristown NJ
Surjit S. Sandhu - Neshanic Station NJ

Assignee:

Inventio AG - Hergiswil NW

International Classification:

B66B 300

US Classification:

116226

Abstract:

A modular signal device which fills the need of the elevator industry for differing types of signal devices wherein a surface mounted base plate includes turned up small ends, with a cover ring surrounding the base plate and utilizing a bolt at one small end and an adjusting screw on the other small end to rearwardly retain the turned up ends, with the cover ring including an inner collar which carries and retains a cover plate, with the cover plate including at least one opening and concentrically arranged second threaded bolts in order to receive switching elements such a push buttons, with first threaded bolts serving to attach the cover plate onto the collar of the cover ring. In further embodiments, the cover plate takes the form of lenses with filters, grids or arrow masks which serve to outwardly convey the signals produced by the signal devices attached to the collar.

Appl. No.:

8/204803

Inventors:

Edward Berdich - Honeybrook PA
Peter Draper - Honeybrook PA
Timothy Shea - Little Falls NJ

Assignee:

Inventio AG - Hergiswil

International Classification:

B60B 300

US Classification:

187398

Abstract:

An elevator operational status indicating element includes a base plate with opposed bent ends mounted on a wall by screws. Pins are provided on the lower side wall of a housing open at the wall side to couple the housing with the lower bent end of the base plate. Setscrews are provided on the upper side wall of the housing to couple the housing with the upper bent end of the base plate. In the front wall of the housing an opening is provided into which a filter plate is set. Threaded bolts, attached near the opening on an inner face of the front wall of the housing, and nuts retain a lens carrier which is pressed against the filter plate. A printed circuit board in the lens carrier carries luminescent diodes in the form of a symbol to be displayed by light transmitted through a lens formed in the lens carrier to the filter plate.

International Classification:

B66B 114

US Classification:

187395

Abstract:

An electronic push button assembly, used as a call and signal generator in elevator controls and installed, via rear surface attachment, in a service control station or indicator board at floor stops and in elevator cars, consists of a push button guide, a carrier plate, an optical acknowledgement device and an electronic portion, wherein the mechanical portion of the push button assembly includes a plunger element, guided and limited for movement by an illuminated ring plate which, through an elastic pressure cap, pressure activates a pressure sensitive resistance FSR when the push button assembly is activated, with the change in resistance of the FSR, resulting from the mechanical pressure, produces a potential change within a voltage divider whereby, via a trigger/preamplifier, a switching transistor is activated and in turn switches on a corresponding load, a potential separation being utilized by the load, via a contact, to complete the acceptance switching circuit, with the basic mechanical construction permitting differing variations relative to design and function.
