Abstract

A water quick disconnect assembly for improving removal of cages from an outside water supply. The assembly automatically turns off a water supply and disconnects a cage from a cage rack system. A water line connector attaches to an outside water supply. A water valve positioned within a cage barrier is locked to the water line connector when water is supplied to the cage. A linking member pivotally attaches to the water line for closing the water line. A knob assembly attaches the linking member to a pull cable. When the pull cable is pulled away from the cage, the water line connector is pivoted in a clockwise direction for disconnecting the water supply to the cage. The knob assembly provides positive visual indication of whether the cage is connected to the water supply or disengaged from the water supply. The quick disconnect system is a positive unlocking system.

Claims

1. A water disconnect assembly in an animal cage rack system, said cage rack system including a cage having at least one wall and an apparatus in said at least one wall, said assembly comprising:

removable water supply means coupled to an inner surface of said wall of said cage for supplying water to an animal wherein said water supply means includes a water line connector attached to a water supply line and a water valve attached to the inner surface of said wall of said cage;

positive disconnect means for disconnecting said cage from said water supply means;

a knob means for activating said positive disconnect means;

said knob means having an outer knob section having a hollow opening therethrough; and

an inner button section positioned within said opening, said inner button section being coupled to said positive disconnect means,

wherein when said cage is connected to said water supply means, said outer knob section is flush against said inner button section and when said cage is disconnected from said water supply means, said inner button section extends from said outer knob section for providing a positive visual indication of connection of said water valve to said water supply line.

2. The assembly of claim 1 wherein a spring biases said inner button section within said outer knob section, said spring extending said inner button section from said outer knob section when said cage is disconnected from said water supply means.

3. The assembly of claim 2 wherein said inner button section is a different color than said outer knob section.

4. The assembly of claim 3 wherein said inner button section is formed of metal.

5. The assembly of claim 3 wherein said inner button section is formed of colored plastic.
