Valve assembly

A valve assembly comprising:

• a tube configured to be inserted between and attached to an inlet pipe for a shower enclosure and a shower head, such that the shower head is in fluidic communication with the inlet pipe, the tube having a first end and a second end, the first end being internally threaded, the second end being externally threaded, such that the first end and the second end are complementary to external threads on the inlet pipe and internal threads of the shower head, respectively;
• a valve positioned in and rotationally attached to the tube, wherein the valve is configured for regulating a flow of water through the tube, the valve comprising a ball valve;
• a housing attached to the tube;
• a shaft attached by a first terminus to the valve and extending through respective sidewalls of the tube and the housing, such that a second terminus of the shaft is external to the housing;
• a rod attached to and extending from the valve into a recess extending into an inner surface of the tube, the rod being opposingly positioned on the valve relative to the shaft, such that the rod is rotatable within the recess and positioned for stabilizing the valve within the tube;
• a biaser positioned in and attached to the housing, the biaser being operationally engaged to the shaft, such that the biaser biases the valve to an open configuration, the biaser comprising a torsion spring;
• a lever arm attached to and extending from the second terminus of the shaft;
• a handle attached to the lever arm distal from the shaft, wherein the handle is configured for grasping in a hand of a user for moving the handle from a first position to a second position for actuating the biaser for rotating the valve from a closed configuration to the open configuration, such that water flows through the tube to the shower head, the handle comprising a chain or a bar;
• a cogwheel positioned in the housing and attached to the shaft, the cogwheel comprising four cogs evenly spaced around a circumference of the cogwheel;
• a pawl engaged to an inner facet of the housing, such that the pawl is positioned for selectively engaging a respective cog as the cogwheel is rotated upon the user pulling the handle, such that each movement of the handle rotates the cogwheel 90° and the valve alternately between the open configuration and the closed configuration;
• and
• a hook configured to be mountable to a wall of the shower enclosure below the inlet pipe, such that the hook is positioned for selectively hooking the chain for fixedly positioning the handle in the first position with the valve in the closed configuration.
