Abstract

A hybrid dispenser incorporating structural elements providing the ability to alternatively dispense soap or other liquid from a container either by an electric motor or manually including a pivoted actuator member having cam surfaces spaced from one another on opposite sides of the pivot location, a rotatable member rotated by the motor engaging one of the cam surfaces, and a manually operable member engaging the other cam surface.

Claims

1. Dispenser apparatus for dispensing liquid soap, lotion or other liquid, said dispenser apparatus including, in combination:

a cabinet defining an interior for holding a container containing liquid and dispensing valve structure connected to said container to dispense liquid from said container;

valve actuator mechanism connected to said cabinet for operating said dispensing valve structure to dispense liquid from the container when said container and dispensing valve structure are held within said interior;

an electric motor; and

a manually operable member movably mounted relative to said cabinet and accessible from a location external of said cabinet, said electric motor and said manually operable member selectively alternatively cooperable with said valve actuator mechanism to cause said valve actuator mechanism to operate said dispensing valve structure and dispense liquid from said container, said valve actuator mechanism including a rotating member rotatable by said electric motor when said electric motor is energized and a double-ended actuator member mounted for pivotal movement relative to said cabinet about a pivot axis located between the ends thereof, said actuator member alternatively selectively engageable by said manually operable member and by said rotating member to pivot said actuator member about said pivot axis and cause operation of said dispensing valve structure and dispensing of liquid from said container by said dispensing valve structure, said actuator member including a top and a bottom, said bottom having first cam surface spaced from said pivot axis and located at one side of said pivot axis engageable by said manually operable member, and said actuator member responsive to pressure applied thereto by said manually operable member at said first cam surface to pivot and operate said dispensing valve structure, and the top of said actuator member having a second cam surface spaced from said pivot axis and located at the other side of said pivot axis engageable by said rotating member and responsive to pressure applied to said actuator member by said rotating member at said second cam surface to pivot said actuator member and operate said dispensing valve structure, said rotating member slidably engageable with said second cam surface during rotation of said rotating member, said actuator member being operatively connected to said dispensing valve structure adjacent to said first cam surface, and said second cam surface and said rotating member disengaged when said manually operable member applies pressure to said actuator member at said first cam surface.

2. The dispensing apparatus according to claim 1 wherein said rotating member includes a projection slidably engageable with said second cam surface during rotation of said rotating member.

3. The dispensing apparatus according to claim 1 additionally including visual indicators for indicating when said dispensing apparatus is in condition for non-manual operation by said electric motor.

4. The dispensing apparatus according to claim 1 additionally including counter means for counting the total number of times liquid is dispensed from said container due to operation of said actuator member by either said electric motor or said manually operable member.

5. The dispensing apparatus according to claim 1 additionally including lock-out structure allowing only specific container and dispensing valve structure combinations to be utilized.

6. The dispensing apparatus according to claim 4 wherein the counter means includes a switch operatively associated with said actuator member.

7. The dispensing apparatus according to claim 6 wherein said switch includes a switch element engageable with said actuator member.
