Abstract
A handicapped-entrance gate for retrofitting a train-station comprises a door panel that forces itself normally closed, but can be pushed open from either side. A closing mechanism is fully contained within a cap rail along to top edge of the door and operates in either direction to close the gate slowly after it has been opened. Fixed axles enter the gate panel from above and below on the pivoting side. The closing mechanism is geared to at least one of these fixed axles to allow the gate to be opened easily and to self-close over a period of time. Springs are used in opposition to hydraulic dampers such that the springs close the gate and the dampers delay the closing.
Claims2
A gate and fence system, comprising:
- a floor-mounted fence with an opening;
- an upper and a lower pivot axle placed at one side of said opening;
- a swinging gate disposed in said opening and pivotally supported on the upper and lower pivot axles, and able to be pushed open from both sides of the fence;
- a thin panel with no front or back surface openings, and which is disposed across the full width of the swinging gate, and for preventing the catching of people passing through said opening;
- a cap rail that tops the thin panel and spans across said full width, and that is thicker front-to-back than the thin panel;
- a gate closer disposed inside the cap rail and which provides for a delayed re-closing of the swinging gate after being opened;
- a hydraulic damper disposed in the gate closer and mechanically providing for said delayed re-closing of the swinging gate after being opened;
- a compression spring disposed in the gate closer and mechanically providing for a re-closing of the gate after being opened;
- a rack gear connected to the hydraulic damper and able to act on the compression spring when the swinging gate is opened;
- and
- a pinion gear engaged with the rack gear and fixed to the upper pivot axle such that a decompression of the spring provides for a twisting action that can close the swinging gate.
A gate and fence system, comprising:
- a floor-mounted fence with an opening;
- an upper and a lower Divot axle placed at one side of said opening;
- a swinging gate disposed in said opening and pivotally supported on the upper and lower pivot axles, and able to be pushed open from both sides of the fence;
- a thin panel with no front or back surface openings, and which is disposed across the full width of the swinging gate, and for preventing the catching of people passing through said opening;
- a cap rail that tops the thin panel and spans across said full width, and that is thicker front-to-back than the thin panel;
- a gate closer disposed inside the cap rail and which provides for a delayed re-closing of the swinging gate after being opened;
- a pair of oppositely acting hydraulic dampers disposed in the gate closer and mechanically providing for said delayed re-closing of the swinging gate after being opened in either direction;
- a set of springs disposed in the gate closer and mechanically providing for a re-closing of the swinging gate after being opened;
- a pair of oppositely acting rack gears respectively connected to each of the hydraulic dampers and able to act on the set of springs when the swinging gate is opened;
- and
- a pinion gear engaged with each of the pair of oppositely acting rack gears, and which is fixed to the upper pivot axle such that a relaxation of the set of springs provides for an appropriately directed gate-closing twisting action.
