Dispenser with multi-directional pushbar
A product dispenser includes a housing adapted to receive a refill unit having a product reservoir. A multidirectional pushbar is carried by the housing and movable in a plurality of directions to actuate the pump. The multidirectional pushbar may be carried by a collar pivotally secured around a pushbar support member in the shape of a spherical zone. Pivoting movement of the multidirectional pushbar is converted into an actuating force by a transfer mechanism, which may include a vertically movable carriage. In other embodiments, the multidirectional pushbar may include ramped surfaces and may support a carriage having rolling elements. Lateral movement of the multidirectional pushbar causes the carriage to roll up the ramped surfaces and actuate a pump to dispense a product.
1. A product dispenser comprising:
a housing adapted to selectively retain a replaceable product refill unit associated with a piston pump;
a transfer mechanism associated with the piston pump;
a multidirectional pushbar movable about a plurality of axes and associated with the transfer mechanism, wherein, in response to movement of the multidirectional pushbar about an axis of the plurality of axes, the transfer mechanism engages the piston pump to dispense product from the replaceable product refill unit; and
a pushbar support member, the multidirectional pushbar defining an interior within which the pushbar support member is received, wherein the pushbar support member is movable about the axis of the plurality of axes in response to the movement of the multidirectional pushbar.
2. The product dispenser of claim 1 , wherein the pushbar support member engages the transfer mechanism when the pushbar support member is moved about the axis such that the transfer mechanism applies an axial force to the piston pump to dispense the product from the replaceable product refill unit.
3. The product dispenser of claim 1 , wherein the transfer mechanism comprises a ring that engages the piston pump to dispense the product from the replaceable product refill unit.
4. The product dispenser of claim 3 , wherein the transfer mechanism comprises a flexible finger that is attached to the multidirectional pushbar and the ring, and the flexible finger deforms upon movement of the multidirectional pushbar about the axis.
5. The product dispenser of claim 4 , wherein the deformation of the flexible finger causes movement of the ring along a central axis such that the ring applies an axial force to the piston pump.
6. A product dispenser comprising:
a housing adapted to selectively retain a replaceable product refill unit associated with a piston pump;
a transfer mechanism associated with the piston pump; and
a multidirectional pushbar movable about a plurality of axes and associated with the transfer mechanism, wherein:
in response to movement of the multidirectional pushbar about an axis of the plurality of axes, the transfer mechanism engages the piston pump to dispense product from the replaceable product refill unit,
the transfer mechanism comprises a ring that engages the piston pump to dispense the product from the replaceable product refill unit, and
the transfer mechanism comprises a flexible finger that is attached to the multidirectional pushbar and the ring, and the flexible finger deforms upon movement of the multidirectional pushbar about the axis.
7. The product dispenser of claim 6 , comprising a pushbar support member, the multidirectional pushbar defining an interior within which the pushbar support member is received.
8. The product dispenser of claim 7 , wherein the pushbar support member is movable about the axis of the plurality of axes in response to the movement of the multidirectional pushbar.
9. The product dispenser of claim 8 , wherein the pushbar support member engages the transfer mechanism when the pushbar support member is moved about the axis such that the transfer mechanism applies an axial force to the piston pump to dispense the product from the replaceable product refill unit.
10. The product dispenser of claim 6 , wherein the deformation of the flexible finger causes movement of the ring along a central axis such that the ring applies an axial force to the piston pump.
11. A product dispenser comprising:
a housing adapted to selectively retain a replaceable product refill unit associated with a piston pump;
a transfer mechanism associated with the piston pump; and
a multidirectional pushbar movable about a plurality of axes and associated with the transfer mechanism, wherein:
in response to movement of the multidirectional pushbar about an axis of the plurality of axes, the transfer mechanism engages the piston pump to dispense product from the replaceable product refill unit, and
the multidirectional pushbar comprises a wall having a first ramped surface and a second ramped surface, and the first ramped surface and the second ramped surface define a valley.
12. The product dispenser of claim 11 , wherein the transfer mechanism comprises a rolling element that is received within the valley.
13. The product dispenser of claim 12 , wherein the rolling element engages at least one of the first ramped surface or the second ramped surface.
14. The product dispenser of claim 13 , wherein the rolling element is movable along at least one of the first ramped surface or the second ramped surface in response to the movement of the multidirectional pushbar.
15. The product dispenser of claim 14 , wherein the transfer mechanism comprises a carriage and movement of the rolling element along at least one of the first ramped surface or the second ramped surface causes movement of the carriage along a central axis such that the carriage applies an axial force to the piston pump to dispense the product from the replaceable product refill unit.
