Abstract

A locking mechanism for a nozzle in an inflatable object includes a membrane member having a ledge extending outward for securely engaging with the inflatable object, a nozzle seat having a flange to firmly engage with the ledge, a positioning element having two arms, a cap having a lifting mechanism to elevate location of the positioning element, a descending mechanism to descend the location of the positioning element and a sealing part integrally formed and a sealing part integrally extending from the flange and a core having a directing rod securely connected to the positioning element so as to move with the positioning element accordingly and a sealing flange formed with the directing rod such that movement of the core together with the positioning element allows the sealing flange to selectively and sealingly engage with the sealing part of the nozzle seat to block airflow.

Dependent claims

A locking mechanism for a nozzle in an inflatable object, the locking mechanism comprising:

a membrane member having a ledge extending outward for securely engaging with the inflatable object;
a nozzle seat having a flange formed to engage with a face of the ledge of the membrane member and a sealing part integrally extending from the flange
a positioning element movably received at least partially inside the nozzle seat and having at least one arm extending outward;
a cap rotatably connected to a portion of the nozzle sea, the cap and having a lifting mechanism to elevate a location of the positioning element and a descending mechanism to descend the location of the positioning element;
and
a core received inside the nozzle seat, the core having a directing rod extending in a first direction and connected to the positioning element so as to move with the positioning element accordingly and a sealing flange formed with the directing rod such that movement of the core together with the positioning element allows the sealing flange to selectively engage with the sealing part of the nozzle seat to block airflow;
wherein the cap has a passage for airflow to flow into and escape from the inflatable object, a holding part, a neck axially extending from an inner face of the cap and a cavity defined between the holding part and the neck, and wherein the nozzle seat has a collar integrally and axially extending in a first direction from the flange to securely fit into the cavity of the cap so as to engage the nozzle seat with the cap.
