Abstract
A cattle gate has a base frame adapted to rest on a ground surface. Upright end frames are secured to the base frame at opposite ends and suspend a grid over the center of the base frame using a spring and chain suspension. The gate is a unitary structure that can be transported either using a truck or by attaching a pair of wheels and a hitch for towing purposes.
Claims5
A cattle gate comprising,
- a rectangular grating formed by a plurality of elongate parallel rigid grating bars and two transverse end beams each rigidly connected to the bars at right angles thereto to a respective end of each of the bars;
- a rectangular base frame adapted to rest upon a ground surface and comprising a first rigid transverse beam member at a first end of the base frame, a second rigid transverse beam member at a second end of the base frame, a first rigid frame element rigidly connected to said rigid transverse beam members, a second rigidly frame element parallel to the first frame element and rigidly connected to said rigid transverse beam members, the first and second frame elements lying parallel to the grating bars and being separate therefrom to allow vertical movement of the grating relative to the frame element, the base frame surrounding the grating such that the grating can lie on the ground surface wholly within the base frame;
- a first and a second upright member each connected to a respective one of the rigid transverse beam members, reinforcing means connecting said upright members and said frame for providing reinforcement to maintain the upright member in upright orientation such that the upright member is wholly supported by the frame and;
- first and second resilient suspension means each connected between a respective one of the upright members and the grating and arranged to support at least a part of the grating spaced from the ground, the suspension means being resiliently deformable to allow the grating to be pushed to the ground within said base frame under weight from a vehicle.

- at least one of the frame elements including extension portions thereof extending outwardly beyond each of the rigid transverse beam members, and first and second brace means each extending from a respective one of the upright members to a respective one of the extension portions such that the upright members are wholly supported by the frame.
