摘要： A fastener for releasably securing a member comprises a body including a shank and a recess, the recess configured for receiving the member. A gate is mounted to slide axially on the shank between a closed position closing a mouth of the recess for retaining the member, and an open position. Resilient means engages the gate and the shank to urge the gate to the closed position, and latches are mounted on opposing sides of the gate, wherein each latch is self-closing and engages the body for holding the gate in the closed position providing an auto-locking fasteners that for greater security requires three independent actions for release.

摘要： A fastener for securing together articles, such as pull-tabs of a zipper, includes a gate arranged to slide in a channel in a body between a closed position, in which the gate closes the mouth of a recess in the body, and an open position, in which the mouth is open. A fixture at one end of the gate is provided for connecting a tether. A latch member prevents the gate from sliding from the closed position when in the locked position and is resiliently urged to the locked position and configured so that, in use, the latch member is pressed and moved to the unlocked position when a user grasps the body and, in the unlocked position with a tether connected to the fixture, tension in the tether tends to slide the gate to the open position.

摘要： Improved latches for overhead corners which reduce the susceptibility of bundled frame components becoming unlatched and separated due to insufficient torque of latch knobs or to repeated shock. The improved latches retain the prior art notched latches along with their strength and simplicity, but are capable of absorbing shock by accommodating a rotational dynamic present in a latch-to-strike connection rather than attempting to prevent it. One of two styles of moveable, pressure-actuated latch keepers is joined to a notched latch of an overhead frame. One style of keeper provides a barrier into the latch's notch, while another style of keeper provides a barrier relative to the strike's features. The latch keepers provide a predetermined amount of resistance to a radial force applied to the latch. This force retains the strike into the latch's notch in a fully-seated orientation, yet allows for the beneficial shock-absorbing rotational movement of the latch to the strike. This use of pressure-actuated keepers eliminates the need for the prior art latch knob and thus also eliminates the subjectivity associated with determining the proper degree of torque required to sufficiently secure the latch to the strike under a range of conditions.
