  • Patent number: 4803760
    Abstract: The present invention discloses an improved coupling system capable of releasably joining and two or more of a variety of cooperative male/female mating items to be temporarily joined and released by a remotely positioned operator by means of a cable connected to the male member. Spring-biased positive forces within the female assembly otherwise tending to separate the male/female members are used to reliably capture the male component. A relatively small adjustable triggering force activated by the cable moving an activating pin triggers ejecting movement of the female capturing members. The male member forms a cavity containing gripping members that slidably grip the cable. The cavity is accessible to the operator.

  • Patent number: 4797984
    Abstract: A buckle is constructed of a base, latch piece, holding member and release member. The base has a bottom wall and side walls defining substantially L-shaped holes. The latch piece is supported on the base rockingly between a tongue latching position and a tongue non-latching position. The holding member is received at both end portions in the holes displaceably between a holding position, where the end portions are in the horizontal portions of the corresponding holes so as to hold at the latching position the latch piece which has been in the latching position, and a non-holding position where the end portions are in the vertical portions of the corresponding holes so as to permit movement of the latch piece from the latching position. The release member is provided displaceably between a non-operated position and an operated position and adapted to bring the holding member to the non-holding position and the latch piece to the non-latching position when the release member assumes the operated position.

  • Patent number: 4733444
    Abstract: A seat belt buckle comprises a pivoted latch plate biased to a latched position and kept in that position by a control member slidably carried on the latch plate and biased to a position in which blocking portions cover notches at the edges of the latch plate. Control projections on the sides of a channel-shaped frame are engaged by the blocking portions in the latched position but accept the notches in the latch plate when the control member is moved by a release button to uncover the notches. Cam surfaces on the frame sides coact with cam follower surfaces on the control member to lift the control member and latch plate when the release button is depressed. Anchor projections on the frame sides are received in the notches in the latch plate in the latched position and transfer loads from the latch plate to the frame.
