Safety gate assembly

摘要

A safety gate is composed of a U-shaped frame and a door spanning the interior of the frame. One side of the door is pivotally connected to one side of the frame to permit pivotal movement of the door with respect to the frame. The frame's width is adjusted by a ratchet mechanism composed of a spring-loaded pawl having a sloping side and a vertical side so that the width of the frame can be adjusted in one direction only.

主权项

1. A safety gate comprising
(a) a frame including two generally vertically extending pillars, each of said pillars having a top end and a bottom end, and each of said pillars having a cross bar attached to the bottom end of the pillar and extending horizontally and substantially perpendicularly from the bottom end of the pillar, and a hollow surround bar being formed and positioned so that said cross bars rest at least partially inside the hollow surround bar, said cross bars being telescopingly movable relative to said hollow surround bar and horizontally movable, at least one of said cross bars being formed with an array of catches in one side thereof, the frame forming a U-shaped structure having an interior and being width adjustable; (b) a door spanning the interior of the frame and pivotally connected to an interior side of one of said frame pillars for movement of the door about a pivot axis; (c) means for engaging one of said catches in said array of catches and allowing horizontal, linear motion of said one of said cross bars relative to and within the surround bar only in a single direction to increase a width of the frame, said means for engaging one of said catches being positioned within said one of said cross bars; and (d) a cantilever foot pedal operatively connected to the surround bar and rotatable between an upward and open position and a downward and closed position to telescopingly move the surround bar relative to the other one of said cross bars to increase or decrease the width of the frame and to lock and unlock the frame.
