Abstract
Cantilever gates (10) in the form of parallelograms include first and second bars (40) and a toe board (140) extending between and pivotally mounted to first and second posts (20, 30) and moveable between closed and open positions. Gas struts (46) assist in moving the gate (10). A lock (60) in the form of a pivotal latch (62) holds the gate (10) in its open position. A slide receptor (80) slideably receives the second post (30) as the gate (10) moves from the open to the closed position and can be removably secured to the support surface mounting plate (82). A pair of cantilever gates (10) can have their respective second posts (30) slideably related.
Claims15
A cantilever gate comprising, in combination:
- a first post fixed to a support surface;
- a second post;
- first and second bars extending between and pivotally mounted to the first and second posts to define a parallelogram movable between a closed position and an open position, with the bars being generally parallel to the support surface in the closed position and at an acute angle to the support surface in the open position;
- and a slide receptor for slideably receiving the second post therein when the parallelogram is in the closed position, wherein the second post has a lower end contacting the support surface in the closed position of the parallelogram and with the slide receptor slideably receiving a portion of the second post which is spaced from the lower end of the second post when the parallelogram is in the closed position, wherein each of the first and second bars terminate in first and second ends, with the first ends of the first and second bars pivotally mounted to the first post and with the second ends of the first and second bars pivotally mounted to the second post, wherein the second post and the slide receptor each includes first and second legs integrally connected to an interconnection plate, with the second ends of the first and second bars located intermediate the first and second legs of the second post, with the first and second legs of the second post located intermediate the first and second legs of the slide receptor when the parallelogram is in the closed position.

- a slide receptor for slideably receiving the second post therein when the parallelogram is in the closed position;
- a mounting plate fixed to the support surface, with the mounting plate having first and second lugs slideably receiving the slide receptor, with the slide receptor being intermediate the first and second lugs of the mounting plate, with the mounting plate further having a joist extending between the first and second lugs and abutting with the slide receptor;
- a tube secured to the slide receptor;
- and a pin extending through the first and second lugs and the tube.
