Abstract
A latching device capable of being remotely released and a method of remotely releasing a locking tab from a locking body. The latching device includes a locking tab comprising a shaft with an engaging recess and a head with a buckle; a locking body comprising a slide with a channel for the shaft of the locking body, a ramp and shoulder for securing the locking tab, a leg with a trigger surface, an ejector pin and ejection spring for ejecting the locking tab from the locking body and a slide biasing spring; a trigger comprising a knob, shank and foot; and an extension for attaching the latching device to a brace holding fire fighting equipment.
Claims12
A remote release latching device, comprising:
- a locking tab which has an engaging recess;
- a locking body which includes a housing;
- a locking ramp internal to the housing so that the ramp is capable of interaction with the locking tab's engaging recess upon insertion of the locking tab;
- an ejector which includes a spring contacting a pin which are placed within the housing so that the ejector abuts the locking tab after insertion into the housing;
- a trigger surface contacting the locking ramp;
- and
- a trigger which passes through the housing, is adjacent to the trigger surface, is capable of movement perpendicular to the housing, and is adapted to receive a lanyard.
A remote release latching device, comprising:
- a locking tab which has an engaging recess;
- a locking body which includes a housing;
- a channel internal to the housing which allows insertion of the locking tab;
- a locking ramp internal to the housing so that the ramp is capable of interaction with the locking tab's engaging recess upon insertion of the locking tab;
- an ejector which includes a spring contacting a pin which are placed within the housing so that the ejector abuts the locking tab after insertion into the housing;
- a trigger surface contacting the locking ramp;
- a trigger which passes through the housing, is adjacent to the trigger surface and is capable of movement perpendicular to the housing;
- and
- a lanyard attached to said trigger.
A remote release latching device, comprising:
- an oxygen tank holder;
- a locking tab which has an engaging recess;
- a locking body which includes a housing and is attached to the tank holder;
- a channel internal to the housing which allows insertion of the locking tab;
- a locking ramp internal to the housing so that the ramp is capable of interaction with the locking tab's engaging recess upon insertion of the locking tab;
- an ejector which includes a spring contacting a pin which are placed within the housing so that the ejector abuts the locking tab after insertion into the housing;
- a trigger surface contacting the locking ramp;
- a trigger which passes through the housing, is adjacent to the trigger surface and is capable of movement perpendicular to the housing;
- and
- a lanyard attached to said trigger.
A method of using a remote release latching device, comprising the steps of:
- insertion of a locking tab which has a locking recess into a locking body;
- where a locking ramp engages a locking tab's engaging recess;
- and
- where the locking tab contacts an ejector which also contacts a trigger;
- and
- where at a later time force is applied to the trigger in a direction that is perpendicular to the locking body by pulling a lanyard attached to the trigger;
- and where the movement of the trigger results in the exertion of force upon the trigger surface by the trigger;
- which results in the separation of the locking ramp from the locking tab engaging recess;
- and
- where the ejector exerts a force upon the locking tab which then ejects the locking tab from the channel.
A method of using a remote release latching device, comprising the steps of:
- placing an oxygen tank adjacent to a tank holder where the tank is then secured by;
- insertion of a locking tab which has a locking recess into a locking body;
- where a locking ramp engages a locking tab's engaging recess;
- and
- where the locking tab contacts an ejector which also contacts a trigger;
- and
- where at a later time force is applied to the trigger in a direction that is perpendicular to the locking body by pulling a lanyard attached to the trigger;
- and where the movement of the trigger results in the exertion of force upon the trigger surface by the trigger;
- which results in the separation of the locking ramp from the locking tab engaging recess;
- and
- where the ejector exerts a force upon the locking tab which then ejects the locking tab from the channel.
