Apparatus for dispensing liquid soap
View Patent ↗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. The hybrid dispenser includes an electric motor and a valve actuator mechanism having an elongate pivotable actuator member for operating a dispensing valve structure. A manually operable member is pivotably mounted relative to the cabinet such that the electric motor and the manually operable member selectively independently cooperate with generally opposite ends of the elongate pivotable member to cause the dispensing valve structure to dispense liquid from a container supported by the dispenser.
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 a dispensing valve structure connected to said container to dispense liquid from said container;
a valve actuator mechanism connected to said cabinet and that includes an elongated pivotable actuator member 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 pivotably mounted relative to said cabinet, said electric motor and said manually operable member selectively alternatively cooperable with generally opposite ends of said elongated pivotable member of said valve actuator mechanism to cause said valve actuator mechanism to operate said dispensing valve structure and dispense liquid from said container.
2. The dispenser apparatus according to claim 1 wherein said valve actuator mechanism includes a rotating member rotatable by said electric motor when said electric motor is energized and an actuator member pivotally mounted relative to said cabinet, said actuator member alternatively selectively engageable by said manually operable member and by said rotating member to pivot said actuator member and cause operation of said dispensing valve structure and dispensing of liquid from said container by said dispensing valve structure.
3. The dispenser apparatus according to claim 2 wherein said manually operable member is pivotally mounted on said cabinet and accessible from a location external of said cabinet.
4. The dispensing apparatus according to claim 3 wherein said actuator member has a first cam surface engageable by said manually operable member and responsive to pressure applied to said actuator member by said manually operable member at said first cam surface to pivot said actuator member and operate said dispensing valve structure.
5. The dispensing apparatus according to claim 4 wherein said actuator member has a second cam surface spaced from said first cam surface 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.
6. 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.
7. 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.
8. The dispensing apparatus according to claim 2 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.
9. The dispensing apparatus according to claim 1 additionally including a lock-out structure allowing only specific container and dispensing valve structure combinations to be utilized.
10. The dispensing apparatus according to claim 8 wherein the counter means includes a switch operatively associated with said actuator member.
11. The dispensing apparatus according to claim 10 wherein said switch includes a switch element engageable with said actuator member.
