Abstract
A new inflating device and method for inflating an inflatable object are described. The inflating device includes two compartments: one containing a gas-generating agent and the other containing an activating agent. When mixed, the gas-generating agent and the activating agent produces a gas in situ. The device further includes an activator connected to both compartments and is capable of effectuating mixing between the two agents upon activation. A hose assembly of the inflating device delivers a the gas generated to an inflatable object, such as a flat tire.
Claims18
An inflating device, comprising:
- a first compartment containing a gas-generating agent not in the gaseous state;
- a second compartment containing an activating agent separated from the gas-generating agent, the activating agent capable ofproducing a gas in situ when in contact with the gas-generating agent;
- an activator connected to the first and second compartments, the activator capable of effectuating contact between the gas-generating agent and the activating agent upon activation;
- and a hose assembly having two ends, one end adaptable for connection to an inflatable object, the other end connected to a compartment in which the gas is generated.
An inflating device, comprising:
- a first compartment containing a gas-generating agent not in the gaseous state;
- a second compartment containing an activating agent separated from the gas-generating agent, the activating agent capable of producing a gas in situ when in contact with the gas-generating agent;
- a means for effectuating contact between the gas-generating agent and the activating agent upon activation;
- and
- a means for delivering the gas to an inflatable object.
An inflating device, comprising:
- a first compartment containing a carbonate compound and having a refill port;
- a second compartment containing an acid separated from the carbonate compound, the second compartment having a refill port and located below the first compartment;
- an addition valve connected to the first compartment and the second compartment;
- a pressure equalizer connecting the first and the second compartment;
- a pressure gauge located on the second compartment;
- and
- a gas output port located on the second compartment.
A method for inflating an inflatable object, comprising:
- providing a gas-generating agent not in the gaseous state;
- providing an activating agent separated from the gas-generating agent, the activating agent capable of producing a gas in situ when in contact with the gas-generating agent;
- contacting the gas-generating agent with the activating agent to generate a gas in situ;
- and delivering the gas to an inflatable object.
