Abstract
Pin-locking devices are detailed. The devices may be placed atop inflation valves and mechanically interfere with movement of pins associated with the valves. Some versions of the devices are single-piece, rigid discs including through holes and curved protrusions interacting with inflation pins.
Claims14
A device for preventing movement of a pin within a curved groove, comprising:
- a. a disc having (i) a first surface and (ii) a first hole sized to accommodate the pin;
- and
- b. a curved protrusion extending from the first surface so as to be received by the curved groove when the first hole accommodates the pin.
A system for inhibiting premature inflation of an inflatable object, comprising:
- a. a container of compressed gas;
- b. a valve assembly connected to the container so as selectively to allow gas to flow from the container to the object, the valve assembly including a pin and a groove in which the pin travels;
- and
- c. means for preventing movement of the pin in the groove.
A method of inhibiting premature inflation of an inflatable object, comprising inserting a device into a recess of a valve assembly connected to a container of compressed gas, the device comprising (a) a disc having (i) a first surface and (ii) a first hole sized to accommodate a pin of the valve assembly and (b) a protrusion extending from the first surface so as to be received by a groove of the valve assembly when the first hole accommodates the pin.
