Abstract

A wall mounted soap dispenser made of plastic is described. The dispenser includes a hand-operated pump which dispenses liquid soap under pressure and which can be manufactured inexpensively. A disposable container of liquid soap is inserted in the dispenser to refill the dispenser. The pump has on its top a pan to collect liquid spilled as the disposable container is inserted. The pump and container are enclosed in a plastic housing which hinges from a plastic wall plate. A plastic latch with plastic key is used to lock the housing to the wall mounting plate. The pump mechanism uses a piston of two sections of different diameter and corresponding piston chamber of two sections of different diameter. There is an adjustable piston stroke length limiting mechanism. The piston is attached to the lever which moves the piston by means of a crossbar on the end of the piston rod. The crossbar is inserted in a slot in the lever and then turned to cross the slot.

Claims

1. A locking mechanism for locking two planar members together wherein said first planar member is substantially perpendicular to said second planar member when locked comprising:

an opening in said first planar member,

a cylinder rotatably mounted in said opening, said cylinder having two ends,

said cylinder having a first outwardly radiating flange at said one end and at one side of said planar member,

said cylinder having a second outwardly radiating flange at the other end and at the other side of said planar member,

said cylinder being adapted and constructed to be retained by said first planar member by said first and second flanges,

said second flange having an elongated eccentric portion extending radially and outwardly,

said elongated eccentric portion having a perpendicularly positioned extension,

said extension having a boss,

said first and second flanges having a pair of axially aligned bores therethrough each being disposed 180°

from each other,

elongated key means,

said elongated key means having perpendicularly disposed spaced pin means adapted and constructed to mate with said bore whereby said cylinder is rotated when said key means is manually rotated along an axis perpendicular to the axis of said key,

said second planar member having a latch means adapted and constructed to engage said perpendicularly positioned extension,

said latch means being parallely spaced from said second planar member and said perpendicularly positioned extension is retainingly located against and by said latch means between said latch means and said second planar member when said two members are locked together.
