Abstract
A pressure chamber is formed interiorly within one or more of the hollow tubular members of a cycle frame. Pressurized fluid, such as air, is supplied from the pressure camber by conduits through a pressure regulator and a control valve to a cycle mounted accessory, such as a pressurized fluid container or an inflatable seat. In one embodiment, the fluid container includes an expandable bag which expands as pressurized fluid is supplied thereto. The expandable bag pressurizes the liquid contents of the container to facilitate the discharge of the liquid through a discharge conduit which terminates adjacent the cyclist's face. The pressurization apparatus may also be employed to inflate an inflatable cycle seat or the cycle tires, or to pressurize the cycle frame for stiffness.
Claims7
In a cycle having a frame formed of a plurality of interconnected, tubular members, the improvement comprising:
- at least one of the tubular members having a sealed interior chamber for storing a pressurized fluid;
- first valve means, mounted on the at least one of the tubular members and disposed in fluid flow communication with the interior chamber, for enabling the supply of pressurized fluid into the interior chamber and the discharge of pressurized fluid from the interior chamber;
- second valve means connected in fluid flow communication with the interior chamber;
- the second valve means being manually movable between a first position for discharging pressurized fluid from the interior chamber through the first valve means and a second position blocking the flow of pressurized fluid from the interior chamber;
- and
- a pressurized fluid responsive device mounted on the cycle and connected in fluid flow communication with the first valve means;
- the pressurized fluid responsive device including:
- a hollow container for storing a liquid, the container having an inlet and an outlet;
- an expandable chamber disposed in the container;
- the inlet being disposed in fluid flow communication with the interior chamber and the interior of the expandable chamber such that pressurized fluid supplied through the inlet to the expandable chamber causes the expandable chamber to expand and exert pressure on the liquid in the container;
- and
- discharge valve means, connected in fluid flow communication with the outlet of the container, for selectively discharging liquid from the interior of the container.
