Impact absorbing unitary cover assembly
Apparatus and associated methods relate to a cover assembly having a plurality of ribs integrally formed within an actuator body envelope to increase the resilience of the actuator body envelope against high-pressure water cleaning. In an illustrative example, the actuator body envelope defines an actuator body chamber while an actuator envelope integrally formed with the actuator body envelope defines an actuator chamber. The actuator chamber and the actuator body chamber may adapt to receive an actuator via an insertion aperture at a proximal end of the body envelope. In some implementations, the plurality of ribs may advantageously increase the service life of the cover assembly.
1. A cover assembly to provide hygienic protection for electrical actuators in applications exposed to high-pressure washing, the cover assembly comprising:
an actuator envelope formed from a transparent non-toxic material and defining an actuator chamber;
a transparent non-toxic actuator body envelope formed from a transparent non-toxic material and integrally extending proximally from the actuator envelope and defining an actuator body chamber in fluid communication with the actuator envelope and in fluid communication with ambient atmosphere through an insertion aperture; and,
a plurality of longitudinally extending ribs integrally formed within the actuator body envelope and extending radially inward from a substantially smooth interior surface of the actuator body envelope,
wherein the actuator envelope and the actuator body envelope align along a longitudinal axis and together provide a unitary substantially smooth exterior surface to facilitate the removal of foreign particles when cleaned by a pressure wash,
wherein when an electrical device, which comprises an actuator to receive a user input, and an actuator body to house an electrical circuitry responsive to the actuator, is removably inserted through the insertion aperture, the actuator is disposed in the body chamber, the actuator body envelope forms a seal against a proximal surface of the actuator; and,
wherein the seal provides protection against the ingress of water up to a pressure of 1450 pounds per square inch.
