Vandal-resistant push-button actuator
First Claim
1. A vandal-resistant push-button actuator, comprising:
- a push-button defining a push-button axis;
a push-button mounting means having a passageway therein for slidably receiving the push-button therein coaxially therewith; and
means for forming first and second axially spaced apart, slidable seals between the push-button and the passageway of the push-button mounting means therefore, providing protection against invasion by foreign substances or foreign objects.

Abstract
A vandal-resistant push-button actuator which may be utilized in a vandal resistant, remotely programmable voice communications unit capable of being programmed for automatically calling predetermined telephone numbers. The vandal-resistant push-button actuator employs a push-button, a push-button mounting device having a passageway therein for slidably receiving the push-button, and first and second axially spaced apart seals between the push-button and the passageway. The seals absorb transverse blows to a raised portion of the push-button and a lubricant may be disposed between the seals to prevent an adhesive inserted by a vandal from disabling the actuator. The raised push-button actuator may be disposed inwardly of an escutcheon and shaped to form a concave, ring-shaped surface therewith, thus to inhibit damage to the inner surface of the escutcheon from a hammer blow.

10. A vandal-resistant push-button actuator, comprising:
- a push-button defining a push-button axis;
push-button mounting means having a passageway therein for slidably receiving the push-button therein;
first resilient means disposed between the push-button and the passageway of the push-button mounting means for resiliently absorbing a force applied to the push-button in a direction transverse to the push-button axis; and
second resilient means disposed between the push-button and the passageway spaced apart from the first resilient means for resiliently absorbing a force applied to the push-button in a direction transverse to the push-button axis. - View Dependent Claims (11, 12, 13)

16. A vandal-resistant push-button assembly, comprising:
- a sleeve and escutcheon member having a sleeve end extending in a first direction and an escutcheon end extending in a second direction opposite the first direction, the escutcheon end having a generally conical first surface facing in the second direction and a second surface facing in the first direction for abutting an outer surface of a mounting plate;
a push-button having a push-button head and a shaft;
the sleeve and escutcheon member having a central aperture therethrough extending along an axis thereof, the shaft of the push-button being slidably mounted in the central aperture;
the push-button head having a convex outer surface facing in the second direction and extending outwardly of the conical first surface of the escutcheon end;
the conical first surface of the escutcheon end forming an angle with a plane transverse to the axis of the sleeve and escutcheon member which is smaller than an angle formed between a tangent to the convex outer surface of the push-button head adjacent the conical first surface of the sleeve and escutcheon member and the plane.
- a sleeve and escutcheon member having a sleeve end extending in a first direction and an escutcheon end extending in a second direction opposite the first direction, the escutcheon end having a generally conical first surface facing in the second direction and a second surface facing in the first direction for abutting an outer surface of a mounting plate;

17. A vandal-resistant push-button actuator, comprising:
- a push-button;
push-button mounting means having a passageway therein for allowing slidable movement of the push-button therein coaxially therewith; and
first and second axially spaced apart seals fixed to the passageway so as to respectively form first and second seals between the push-button and the passageway. - View Dependent Claims (18, 19)
