Abstract
Embodiments provide a stand-alone or self-contained gravity-fed emergency shower including a shower head. A water-tight reservoir is provided, the reservoir including an outlet in fluid communication with a shower head, and an air inlet pipe. The air inlet pipe includes an interior end and an exterior end, the interior end extending into the reservoir to a point below the fill level and above the outlet. The air inlet pipe allows air to enter the reservoir as water drains through the outlet, maintaining a substantially constant head pressure at the outlet, thereby resulting in a substantially constant flow rate of water to the shower head.
Claims15
A self-contained emergency shower, comprising:
- a shower stall comprising a tank supporting framework;
- a water-tight reservoir mounted on the tank supporting framework, the water-tight reservoir including an air-tight sealable fluid inlet port, a fluid outlet having a fluid outlet interior end and a fluid outlet exterior end, and an ambient air inlet pipe, wherein the fluid outlet exterior end is in fluid communication with a shower head;
- a valve located between the shower head and the fluid outlet exterior end;
- and
- a valve operating mechanism for opening and closing the valve;
- wherein the ambient air inlet pipe of the water-tight reservoir includes an interior end and an exterior end, the interior end extending into the water-tight reservoir to a point higher than the fluid outlet interior end;
- and
- wherein, when the valve is in a closed state and the fluid inlet port is sealed, the ambient air inlet pipe is the only fluid conduit between the interior of the water-tight reservoir and the exterior of the water-tight reservoir.
A stand-alone emergency shower, comprising:
- a shower stall comprising a ceiling and three walls;
- a shower head mounted in the shower stall, the shower head arranged to be able to deliver water to a person positioned in the shower stall;
- a water-tight reservoir having an interior mounted above the shower stall, the water-tight reservoir including an air-tight sealable fluid inlet port, an outlet port and an ambient air inlet pipe, the outlet port positioned higher than the shower head, and a tube connecting the outlet port to the shower head;
- a valve connected to the tube and located between the shower head and the outlet port of the water-tight reservoir, the valve positioned below than the outlet port;
- and
- a valve operating mechanism for opening and closing the valve, the valve operating mechanism located in relation to the shower stall such that a person positioned in the shower stall can open and close the valve using the valve operating mechanism;
- wherein the ambient air inlet pipe of the water-tight reservoir includes an interior end and an exterior end, the interior end extending into the water-tight reservoir to a point above the outlet port;
- and
- wherein, when the valve is in a closed state and the fluid inlet port is sealed, the ambient air inlet pipe is the only fluid conduit to the interior of the water-tight reservoir.
A stand-alone emergency shower, comprising:
- a tank, the tank having an interior, one or more sides, a top and a bottom, and including a shower head, an air-tight sealable fluid inlet port, an outlet port and an ambient air inlet pipe, the outlet port positioned below the top of the tank and higher than the shower head, the outlet port in fluid communication with the shower head;
- a valve located between the shower head and the outlet port of the tank, the valve positioned lower than the outlet port;
- and
- a valve operating mechanism for opening and closing the valve;
- wherein the ambient air inlet pipe of the tank includes an interior end and an exterior end, the interior end extending into the tank to a point below the top of the tank and higher than the outlet port;
- and
- wherein, when the valve is in a closed state and the fluid inlet port is sealed, the ambient air inlet pipe is the only fluid inlet to the interior of the tank.
