Abstract

Dispenser apparatus for dispensing liquid soap or other liquid including dispensing structure for dispensing the liquid from a container, and an actuator for actuating the dispensing structure either by an electric motor or by manual movement of a cover of a cabinet holding the container and actuator.

Claims

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

a dispenser cabinet defining an interior for holding a container containing liquid and a dispensing structure connected to said container to dispense liquid from the container, said cabinet including a housing and a cover that is movably connected to said housing at respective upper ends thereof such that the cover can move in opposite lateral directions toward and away from the housing;

an actuator mechanism in the cabinet interior for operating said dispensing structure to dispense liquid from the container responsive to movement of the cover toward said housing, the actuator mechanism including a first actuator mechanism and being responsive to engagement and manual movement of the cover relative to the housing to effectuate rotation of the first actuator mechanism about a horizontal axis and relative to the dispensing structure and thereby manual operation of the dispensing structure to dispense liquid from the container, and the actuator mechanism being operable to effectuate powered operation of the dispensing structure to dispense liquid from the container when a motor is operable such that the dispenser apparatus is concurrently configured to effectuate one of manual or automatic operation of the dispensing structure to dispense liquid from the container when the container and dispensing structure are held within the interior;

wherein the dispensing structure is a pump and wherein the first actuator structure is movably mounted so as to pivot relative to the housing and responsive to engagement by and movement of the cover to move relative to the housing and the second actuator structure engaging the pump and axially movable relative to the pump and to the housing, the second actuator structure engaged by the first actuator structure during movement of the cover to manually actuate the pump and dispense liquid therefrom; and

an electric motor operatively associated with the second actuator structure upon energization thereof to move the second actuator structure relative to the pump and the housing to actuate the pump and dispense liquid therefrom.

2. The dispenser apparatus according to claim 1 including a gear train between said electric motor and said second actuator structure.

3. The dispenser apparatus according to claim 2 wherein said gear train includes a gear member engaging said second actuator structure, said second actuator structure movable toward said pump responsive to rotation of said gear member.

4. The dispenser apparatus according to claim 3 additionally including biasing means for reversing rotational direction of said gear member and for moving said second actuator structure away from said pump after actuation of said pump and dispensing of liquid therefrom.

5. The dispenser apparatus according to claim 4 additionally including adjustable stop means limiting movement of said second actuator structure for controlling the amount of liquid dispensed from said pump during actuation thereof by said second actuator structure.

6. The dispenser apparatus according to claim 3 wherein said electric motor and said gear train are incorporated in a module selectively removable from said housing.

7. A dispenser apparatus for dispensing liquid soap, lotion, or other liquid, the dispenser apparatus comprising:

a cabinet defined by a cover that is movably connected to a housing with respect to an upper end and a lower end of the cover and housing, the housing and cover cooperating with one another to define an interior facing cavity configured to substantially enclose a liquid material container within the cabinet;

a dispensing structure disposed in the cavity and configured to cooperate with a liquid material container disposed in the cavity;

an actuator assembly disposed in the cavity and having a power operated dispensing assembly engaged therewith, the actuator assembly configured to actuate the dispensing structure to dispense liquid material from the cabinet in response to manual translation of the cover in a lateral direction that is transverse to a longitudinal direction that extends between the upper and the lower end of the cover toward the housing which causes manual rotation of a first actuator structure about an axis that is transverse to the longitudinal direction and the lateral direction such that the dispenser apparatus is concurrently configured to selectively effectuate one of manual operation of the dispensing structure to dispense a dose of liquid material from the cabinet and automatic operation of the dispensing structure to dispense the dose of the liquid material from the cabinet when the power operated dispensing assembly is actuated and operable;

wherein the first actuator structure extends between the cover and the dispensing structure and a second actuator structure is disposed between the dispensing structure and a motor associated with the power operated dispensing assembly, the second actuator structure configured to actuate the dispensing structure response to operation of the motor; and

a gear train disposed between the motor and the second actuator structure.

8. The dispensing apparatus of claim 7 wherein the first actuator structure and the second actuator structure cooperate with one another such that the second actuator structure is movable in response to manual movement of the first actuator structure and independently moveable relative to the first actuator structure in response to operation of the motor.

9. The dispensing apparatus of claim 7 further comprising a first biasing assembly configured to bias the cover away from the housing and the actuator assembly toward a ready to dispense position and a second biasing assembly configured to bias the second actuator structure of the actuator assembly toward a ready to dispense position.

10. A method of forming a dispenser that includes a cover that is connected to a housing such that the housing and the cover cooperate with one another to define a cavity shaped to receive a liquid material container and such that the cover extends in a longitudinal direction and is moveable relative to the housing about opposite longitudinal ends of the cover and the housing associated with opposite longitudinal ends of the dispenser, a dispensing structure, and an actuator assembly within the cavity for dispensing liquid soap, lotion or other liquid materials from the dispenser, the method comprising:

engaging the actuator assembly with the cover and the dispensing structure such that manual translation of the cover relative to the housing and the opposite longitudinal ends of the cover and the housing causes rotation of a first portion of the actuator assembly disposed near a lower longitudinal end of the dispenser opposite an upper longitudinal end of the dispenser and relative to the cover and the housing causes manual operation of the dispensing structure in a direction aligned with a longitudinal axis of the dispenser to dispense a dose of a liquid material from the dispenser and operation of a power drive system having a gear train that is disposed between a motor and a second portion of the actuator assembly that is independently movable relative to the first portion of the actuator assembly such that operation of the power drive system causes automatic operation of the dispensing structure to dispense the dose of the liquid material from the dispenser and wherein manual or automatic operation of the dispensing structure are selectively initiated to dispense a dose of the liquid material from the dispenser.

11. The method of claim 10 further comprising biasing each of the first portion and the second portion of the actuator assembly toward a ready-to-dispense position.

12. The method of claim 11 further comprising providing a separable connection between the first portion and the second portion of the actuator assembly.

13. The method of claim 12 further comprising translating the second portion of the actuator assembly in the direction aligned with the longitudinal axis of the dispenser in response to manual operation of the first portion of the actuator assembly and translating the second portion of the actuator assembly in the direction aligned with the longitudinal axis of the dispenser independent of the first portion of the actuator assembly during operation of the power drive system.

14. The method of claim 10 further comprising providing an adjustable stop configured to limit operation of the gear train.
