An operating mechanism for plug-type rail car doors includes first and second links connected to respective rotatable first support bars of the door. The links include respective elongated slots at least partially overlapping with one another, wherein each slot receives a respective cam. The cams are rotatable together about a rotational axis which is eccentrically arranged relative to both cams. An actuating lever is connected to the cams to enable an operator to rotate the cams about the rotational axis. The actuating lever is movable such that the first and second links are retracted relative to one another to simultaneously rotate the first and second support bars, and such that the first and second links are extended relative to one another to simultaneously counter-rotate the first and second support bars. A gear train may be provided between the actuating lever and the cams to reduce the necessary manual operating torque.

A foot operable door opener operates, without using one's hands, and without an electrical assist. The entrance cycle is initiated by stepping on a pedal. This force drives the pedal a ¼ turn, engaging a soft wheel to open the door. The pedal is hard linked to a crank arm which goes into a unidirectional crank shaft hub to turn the wheel. The downward pressure from the pedal pivots a ratcheted hinge connected to a bracketed spring-loaded wheel assembly to keep constant pressure to the ground. A gear box or multiple pumps of the pedal turns the wheel two or more 360 degrees rotations, opening the door to allow the entrant to pass until the foot pedal is dis-engaged. This action releases the ratcheting hinge mechanism, allowing the spring assisted wheel assemble to rotate to its original up position, releasing the wheel from the ground, allowing the door to close.

A flap fitting for a piece of furniture includes a compound lever with a door bearing lever, a slope-increasing device, and a mounting plate to which a wing of the piece of furniture is secured. A lateral position and an incline of the mounting plate is adjustable relative to the door bearing lever by the slope-increasing device. The flap fitting includes a housing having two side plates arranged in parallel and at a distance from each other. The compound lever with the door bearing lever and the slope-increasing device being positioned between the side plates in a closing position of the flap fitting.

A sliding door system includes a stationary door frame, a sliding door panel installed in the stationary door frame and movable between a closed and open position, and a handle assembly coupled to the sliding door panel. The handle assembly includes a rack housing installed within a vertical stile of the sliding door panel, a rack positioned within the rack housing and movable between stowed and extended positions, and a handle operatively coupled to a pinion engageable with the rack, the handle being pivotable about a pivot axis between first and second positions. Rotating the handle from the first position to the second position causes the pinion to move the rack to the extended position and into engagement with the stationary door frame, whereby the sliding door frame is forced away from the stationary door frame from the closed position to the open position.

The present invention discloses a foot operated door opener adapted to allow a user to open a door without requiring the use of a hand. The opener comprises a foot support member extending from the base member. The base member configured to be attachable to a bottom surface of a door comprises a plurality of fastener apertures through which screws or similar attachment means may be passed to secure door opener to a door. The foot support member comprises a first portion extending horizontally from the base member, a first arc portion extends outwardly and diverges upwards from the first portion and a second arc portion extends outwardly and diverges downwards from the first portion. The foot support member is configured to be engaged by the user's foot and allows application of force to open the door.
