An exemplary dispenser includes a housing, a receptacle for receiving a container of fluid and an actuating mechanism for causing fluid to be dispensed from the container. The actuation mechanism has a first pivot arm having a pivot point on a first end and a cam on a second end and a second pivot arm having a pivot point a first end and a curved contact surface on a second end. The actuating mechanism includes a pushbar. One of the first and second pivot members is connected to the pushbar. When the pushbar is pushed inward, the cam is configured to travel along the curved contact surface. Movement of the cam along the curved contact surface moves the engagement mechanism upward and downward in a substantially linear motion when the engagement mechanism is connected to a pump to cause the pump to prime with fluid and dispense the fluid. ## Claims ### Claim 1 A manual soap, sanitizer or lotion dispenser comprising: a housing; a receptacle for receiving a container of fluid; and an actuating mechanism for causing fluid to be dispensed from the container; the actuation mechanism having a first pivot arm having a pivot point on a first end, an engagement mechanism connection point at a second end, and a cam located therebetween; a second pivot arm having a pivot point a first end and a curved contact surface on a second end; wherein the first and second pivot points are located below a bottom of the container of fluid; and a pushbar; wherein one of the first and second pivot members is connected to the pushbar; wherein when the pushbar is pushed inward, the cam is configured to travel along the curved contact surface; wherein movement of the cam along the curved contact surface moves an engagement mechanism upward and downward in a substantially linear motion when the engagement mechanism is connected to a pump to cause the pump to prime with fluid and dispense the fluid. ### Claim 2 (depends on 1) The manual soap, sanitizer or lotion dispenser of claim 1 wherein the curved contact surface has a first curved portion and a second curved portion and wherein the second curved portion has a greater slope. ### Claim 3 (depends on 1) The manual soap, sanitizer or lotion dispenser of claim 1 wherein the engagement mechanism comprises a slot for connecting to the second pivot arm. ### Claim 4 (depends on 1) The manual soap, sanitizer or lotion dispenser of claim 1 wherein the pushbar requires 5 pounds or less for over 75% of its full travel length. ### Claim 5 (depends on 1) The manual soap, sanitizer or lotion dispenser of claim 1 wherein the pushbar requires 5 pounds or less for over 50% of its full travel length. ### Claim 6 (depends on 1) The manual soap, sanitizer or lotion dispenser of claim 1 wherein one of the first pivot arm and the second pivot arm has a pivot point near the rear of the dispenser and the other of the first pivot arm and the second pivot arm has a pivot point near the front of the dispenser. ### Claim 7 (depends on 1) The manual soap, sanitizer or lotion dispenser of claim 1 wherein one of the first pivot arm and the second pivot arm is integrally formed with the pushbar. ### Claim 8 A manual soap, sanitizer or lotion dispenser comprising: a housing; a receptacle for receiving a container of fluid; and an actuating mechanism for causing fluid to be dispensed from the container; the actuation mechanism having a first pivot arm having a pivot point on a first end, a cam, and a projection on the second end; the first pivot arm is connected to one of the front portion and rear portion of the dispenser; a second pivot arm having a pivot point on a first end and a curved contact surface along a portion of the pivot arm; the second pivot arm connected to the other of the front portion and rear portion of the dispenser; and a pushbar; wherein one of the first and second pivot members is connected to the pushbar; an engagement mechanism having a connector for connecting to one of the first pivot member and the second pivot member; the engagement member having an receptacle for receiving a pump; wherein the engagement member has a receiving member for receiving the projection on the second end of the first pivot arm; wherein when the pushbar is pushed inward, the cam is configured to travel along the curved contact surface; wherein movement of cam along the curved contact surface moves the engagement mechanism upward and downward to dispense fluid and to prime the pump. ### Claim 9 (depends on 8) The manual soap, sanitizer or lotion dispenser of claim 8 wherein the curved contact surface has a first curved portion and a second curved portion and wherein the second curved portion has a greater slope. ### Claim 10 (depends on 8) The manual soap, sanitizer or lotion dispenser of claim 8 wherein the engagement mechanism comprises a slot for connecting to one of the first pivot arm and the second pivot arm. ### Claim 11 (depends on 8) The manual soap, sanitizer or lotion dispenser of claim 8 wherein the pushbar requires 5 pounds or less for over 75% of its full travel length. ### Claim 12 (depends on 8) The manual soap, sanitizer or lotion dispenser of claim 8 wherein the pushbar requires 5 pounds or less for over 50% of its full travel length. ### Claim 13 A manual soap, sanitizer or lotion dispenser comprising: a housing; a receptacle for receiving a container of fluid; and an actuating mechanism for causing fluid to be dispensed from the container; the actuation mechanism having a first pivot arm having a pivot point and a cam; a second pivot arm having a pivot point on a first end and a curved contact surface; at least one of the first pivot arm and the second pivot arm having an engagement mechanism connection point for slidably engaging an engagement mechanism; and a pushbar formed as a part of one of the first pivot arm and the second pivot arm; the pushbar rotates about the same pivot point as the one of the first pivot arm and the second pivot arm; wherein when the pushbar moves the cam is configured to travel along the curved contact surface to move the engagement member upward and downward in a linear motion; and wherein as the engagement member moves upward and downward, the engagement member moves toward or away from a second end of one of the first pivot arm and the second pivot arm. ### Claim 14 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the curved contact surface has a first curved portion and a second curved portion and wherein the second curved portion has a greater slope. ### Claim 15 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the engagement mechanism comprises a slot for connecting to one of the first and second pivot arms. ### Claim 16 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the pushbar requires 5 pounds or less for over 75% of its full travel length. ### Claim 17 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the pushbar requires 5 pounds or less for over 50% of its full travel length. ### Claim 18 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the engagement mechanism connection point is located proximate the end of the first pivot arm. ### Claim 19 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the first pivot arm comprises a pair of arms. ### Claim 20 (depends on 13) The manual soap, sanitizer or lotion dispenser of claim 13 wherein the second pivot arm comprises a pair of arms.
