Abstract
A safety gate is provided for limiting access to a work area. The safety gate includes a linkage pivotally connected to a support, and front and rear gates each being pivotally connected to one end of the linkage. As the linkage pivots about the support to move one gate upward, while moving the other gate downward, each gate remains substantially parallel to one another. The safety gate also includes a latch mechanism for locking the either of the front and rear gates into a particular position.
Claims18
A safety gate for limiting access to a work area, the safety gate comprising:
- a support;
- and
- a pair of spatially opposed gates pivotally connected to the support, such that as one gate pivots up, the other gate pivots down, each pivoting gate remaining in a position substantially parallel to the position of the other pivoting gate;
- wherein the spatially opposed gates are separated by a linkage pivotally mounted at its midpoint to the support;
- wherein the each of the opposed gates is pivotally connected to the linkage.
A safety gate for limiting access to a work area, the safety gate comprising:
- a support;
- and
- a pair of spatially opposed gates pivotally connected to the support, such that as one gate pivots up, the other gate pivots down, each pivoting gate remaining in a position substantially parallel to the position of the other pivoting gate;
- wherein the spatially opposed gates are separated by a linkage pivotally mounted at its midpoint to the support;
- wherein the linkage includes a pair of substantially parallel members, each pivotally connected to the support.
A safety gate for limiting access to a work area, the safety gate comprising:
- a support for positioning on a floor of the work area;
- a linkage having opposing ends and being pivotally connected to the support;
- and
- a pair of gates, each gate being pivotally mounted to one end of the linkage, such that as the linkage pivots with respect to the support, one gate, while moving in an upward direction, remains substantially perpendicular to the floor, as the other gate, while moving in a downward direction, also remains substantially perpendicular to the floor.
A method for limiting access to a work area, the method comprising the steps of:
- providing opposing gates about the work area pivotally movable relative to one another, each gate when in a closed position having a gate height;
- and
- pivoting one gate downward into the closed position so as to block a first opening into the work area, while allowing the other gate to pivot upward into an open position at least the gate height above a floor of the work area so as to permit access into the work area beneath the other gate, such that each gate remains substantially perpendicular to the ground and substantially parallel to the other gate.
A safety gate for limiting access to a work area, the safety gate comprising:
- a support frame;
- opposed stationary gates blocking access in through opposite sides of the work area;
- a pair of spatially opposed gates, each gate substantially spanning an end of the work area from one of the opposed stationary gates to the other of the opposed stationary gates, the spatially opposed gates being pivotally connected to the support frames so that as one of the spatially opposed gates pivots up, the other of the spatially opposed gates pivots down to block access through one end of the work area, each of the spatially opposed gates remaining substantially perpendicular to the ground while pivoting.
A safety gate for limiting access to a work area, the safety gate comprising:
- a support frame;
- and
- stationary gating about the work area having two access openings to the work area;
- a pair of gates spaced apart and pivotally connected to the support frame, each gate when in a closed position having a gate height, such that as one gate pivots up above one of the two access openings, the other gate pivots down into the closed position to block the other of the two access openings, each pivoting gate remaining in a position substantially perpendicular to the ground while pivoting;
- wherein with the other gate in the closed position, the one gate is in an open position above a floor of the work area by at least the gate height at the one of the two access openings to permit access into the work area beneath the one gate.
