The hinge axis casts a vertical projection relative to the access door when the access door is rotated midway between the closed and fully opened positions so that the bottom frame member can be horizontally positioned in both the closed and fully opened positions without dropping below a horizontal plane.

Abstract: A compact, spring operated, two-way counterbalance system is disclosed for the hinge assembly of an inwardly/outwardly moveable plug-type aircraft passenger door of the type adapted to pivot about an inwardly canted hinge axis whereby a first convolute clock-type spring member is wound during the final stages of downward door-closing movement to provide an outward biasing force for assisting on-board flight attendants in opening the door during that portion of door movement when it must move in an upward direction; and, a second convolute clock-type spring member is provided which is wound during the latter stages of door opening movement when the door is moving in a downward direction, with the second convolute spring member thus providing a biasing force for assisting the on-board flight attendant in pulling the door upwardly and away from the fuselage during upslope door-closing movement.

Abstract: A simple, compact, cantilever-type spring (31) is mounted on the aircraft body structure (22) and is positioned so as to be deflected from its normally unstressed condition to a stressed state (31') by means of a radially projecting roller (39) mounted on and carried by the body-mounted torque tube (35) during at least the final increment of movement of the aircraft door (20) when it is being shifted to its fully opened position so as to store energy in the spring (31) for assisting in closing of the door (20) and counterbalancing the hinge moment attributable to the weight of the door (20) when the door is moving upslope during a door closing operation and for thereby minimizing the exertion of the on-board flight attendant (29) who is required to apply torque manually by pulling upwardly and outwardly thereon to overcome the door hinge moment until such time that the door (20) begins its downslope travel about the canted hinge axis (35).

Abstract: A pair of swingable gate sections include respectively associated latching mechanisms for normally latching the gate sections in a closed position and further include a pair of spaced triggering members engageable by an approaching vehicle for automatically activating the latching mechanisms to unlatch the gate sections and allow the latter to be swung to an open position under the force exerted by the vehicle as the latter passes through the gated area. The gate sections are respectively mounted by inclined hinges on a pair of spaced supporting members whereby the gate sections are automatically drawn under the influence of gravity back to their closed positions after the vehicle has passed therethrough whereupon the latching mechanisms automatically relatch the gate sections in their closed positions.

Abstract: A self-closing gate incorporating a child-proof latch designed for constructing enclosures restricting accessibility thereto by small children. The self-closing gate comprises a gate, first and second vertically extending gate posts positioned at each side of the gate, and upper and lower gate hinges extending between the first gate post and one side of the gate. The upper and lower gate hinges are non-vertically aligned so as to provide a self-closing action to the gate. A gate latch extends between the second gate post and the opposite side of the gate, which by means of its design, restricts the gate to opening in one direction only, thus allowing access to the latch only by reaching over the gate.

Abstract: This invention relates to an improved hinge for gates, and more particularly, to hinges for chain link fence gates characterized in one embodiment in that they provide automatic gate closing, despite uneven terrain. Further, in a second embodiment, the improved hinge system provides gate openings up to 180.degree.. The expanded mode of operation is effected by offsetting the lower or both hinge pivot points respectively from the center line of the fence. The offset, provided by an improved hinge design including an angular extension of the gate hinge member, is effected while maintaining the coincidence of the center lines of the gate and fence.
