Abstract: A hinged safety gate can include a gate frame and a retainer assembly. The gate frame can have a distal upright member, an upper cross-arm, and a lower cross-arm. The hinged safety gate can have a retainer assembly that is configured to be attached to a proximal end of the gate frame and to hingedly couple the gate frame to a stationary vertical surface, permitting the gate frame to swing between an open position and a closed position. The gate frame is horizontally adjustable in two different manners relative to the retainer assembly to accommodate a range of access area widths.

Abstract: Apparatus and methods for assembling, installing, and operating a manually operated gate (e.g., a safety gate). The manually operated safety gate can include a gate frame and a spring assembly. The gate frame can include a proximal upright member, a distal upright member, an upper arm, and a lower arm. The proximal upright member can be anchored to a stationary surface. The upper arm and lower arm can be pivotably coupled to the proximal upright member and distal upright member to form a parallelogram. The manually operated gate can be configured to pivot between self-close position and a closed position at a constant angular velocity. A kit can contain the required structural components and instructions and can be used to assemble the manually operated gate assembly.

The upper arm and lower arm can be pivotably coupled to the proximal upright member and distal upright member to form a parallelogram. The manually operated gate can be configured to pivot between an open position and a closed position at a constant angular velocity. The gate can freely pivot to the closed position from a self-close position. A kit can contain the required structural components and instructions and can be used to assemble the manually operated gate assembly.
