Abstract
A quick release device comprises an anchor to couple to a safety helmet and a latch to couple to a tether. The anchor may include a cylindrical wall with an indentation circumferentially located thereon. The latch is configured to be attached to and removed from the anchor and may include a barrel, a plurality of ball bearings, and a push-pull button. The barrel may include a sidewall in which the ball bearings are rigidly retained when the latch is in a locked state and the ball bearings are loosely retained when the latch is in a released state. The push-pull button may cover one end of the barrel and may be pushed to attached the latch to the anchor and pulled to remove the latch from the anchor.
Claims17
A quick release device comprising:
- an anchor including a cylindrical wall with a circumferential indentation;
- and
- a latch configured to be attached to and removed from the anchor, the latch including:
- a base;
- a barrel with a sidewall extending from the base and having at least one ball bearing passthrough;
- at least one ball bearing retained in the at least one ball bearing passthrough of the sidewall;
- a push-pull button covering one end of the barrel;
- and
- a ring positioned in the push-pull button, the ring having an inner surface comprising:
- one or more grooves;
- and
- a band extending annularly through the one or more grooves so as to divide each of the one or more grooves into a proximal portion and a distal portion,
- wherein the proximal portion of the one or more grooves becomes aligned with the at least one ball bearing passthrough so that the anchor can urge the at least one ball bearing at least partially into the proximal portion of the one or more grooves when the push-pull button is pushed towards the base to a push-attach position for attaching the latch to the anchor;
- the distal portion of the one or more grooves becoming aligned with the at least one ball bearing passthrough so that the anchor can urge the at least one ball bearing at least partially into the distal portion of the one or more grooves when the push-pull button is pulled away from the base to a pull-release position for removing the latch from the anchor;
- and
- the band urging the at least one ball bearing into the circumferential indentation of the cylindrical sidewall of the anchor when the latch is attached to the anchor and the push-pull button is in a neutral position.
A quick release device comprising:
- an anchor including a cylindrical wall with a circumferential indentation;
- and
- a latch configured to be attached to and removed from the anchor, the latch including:
- a barrel with a sidewall;
- at least one ball bearing retained in the sidewall;
- and
- a push-pull button covering one end of the barrel and comprising:
- one or more grooves having a proximal portion and a distal portion separated from the proximal portion;
- and
- a band positioned in the one or more grooves between the proximal portion and the distal portion,
- wherein the latch has a released state and a locked state and the latch is placed in the released state when the push-pull button is pushed from the locked state and when the push-pull button is pulled from the locked state;
- the band of the push-pull button rigidly retaining the at least one ball bearing in the sidewall when the latch is in the locked state;
- the proximal portion of the one or more grooves being aligned with the at least one ball bearing for at least partially receiving the at least one ball bearing in the proximal portion when the latch is in the released state and the push-pull button is pushed;
- and
- the distal portion of the one or more grooves being aligned with the at least one ball bearing for at least partially receiving the at least one ball bearing in the distal portion when the latch is in the released state and the push-pull button is pulled.
