Abstract
A drive-over gate includes an elongate enclosure adapted to receive a motor vehicle having a first gate positioned at a first end and a second gate positioned at a second end. Cable linkages extend between the first gate and the second gate. When the motor vehicle drives in a first direction through the enclosure, it forces the first gate into the horizontal position and causes the cable linkage to pull the second gate to the upright position behind the motor vehicle. When the motor vehicle drives in a second direction through the enclosure, it forces the second gate into the horizontal position and causes the cable linkage to pull the first gate to the upright position behind the motor vehicle.
Description
TITLE OF THE INVENTION:
Drive-over gate FIET~D OF THE INVENTION
The present invention relates to a drive-over gate.
BACKGROUND OF THE INVENTION
Drive-over gates pivot about a horizontal pivot axis between an upright position and a horizontal position. A
force exerted by a motor vehicle, moves t:ne gate from the upright position to the horizontal posii~ion. After the motor vehicle has passed, a force exerted by either a bs_asing spring or a counter-weight moves the gate back to the upright position.
It has long been recognized that problems can arise if the biasing spring or counter-weight returns the gate to the upright position too quickly. The gate can damage the under-carriage of the motor vehicle, or present a hazard to pedestrians. For this reason, hydraulic cylinders are used to slow the motion of the gate as it moves from the horizontal position back to the upright position.
SU'N~IARY OF THE INVENTION
The present invention relates to an alternative construction of drive-over gate.
According to the present invention there is provided a drive-over gate which includes an elongate enclosure adapted to receive a motor vehicle. The enclosure having a firsi: end and a second end. A first gate positioned at. the first end of the enclosure for pivotal movement about a first horizontal pivot axis between an upright position and a horizontal position. A second gate positioned at the second end of the enclosure for pivotal movement about a second horizontal pivot axis between an upright. position and a horizontal position. The second gate is in ~_he upright position when the first gate is in the horizontal position.
Cable linkages extenc. between the first gate and the second gate. When the motor vehicle drives in a first direction through the enclosure, it forces the first g<~te into the horizontal position and causes the cable lineage to pull the second gate to the upright position behind the motor vehicle.
T~~hen the motor vehicle drives in a second direction through 1C the enclosure, it forces the second gate into the horizontal position and causes the cable linkage to pul=L the first gate to the upright position behind the motor vehicle.
The drive-over gate, as described above, is of simple ~_5 construction and operates without biasing springs, counter-weights, or hydraulic cylinders. There are some additional features which can be added to enhance t:he performance of the drive-over gate and expand its functionality, as will hereinafter be further described.

In the illustrated embodiment, first date 18 is in the horizontal position. A second gate 22, positioned at second end 16 of enclosure 1.2, is adapted for pivotal movement about a second horizontal pivot axis 24 between an upright position and a horizontal position. In the illustrated embodiment, second gate 22 is in the vertical position. Cable linkages 26 having opposed ends 28 link first gate 18 and second gate 22. It should be app>reciated that there may be variations in the mode of construction and the means by which cable linkages 26 may be routed. In the i7_lust:rated embodiment, drive-over gate 10 is made of steel tubing and cable linkages 26 run within a top rail 29 of enclosure 12. Means may be provided to adjust the length of cable linkages 26. In the illustrated embodiment, at least one turnbuckle 30 is included as part of cable linkages 26. Referring to FIGURE
2, means may also be provided for guiding cable linkages 26"
In the illustrated embodiment, bushings 32 are positioned to guide cable linkages 26 toward the other gate. Means may further be provided for detachably securing at least one of opposed ends 28 of cable linkages 26 from either first gate 18 or second gate 22. In the illustrated embodiment, an end hook 34 is adapted to engage one end of turnbuckle 30. It will be appreciated that other means of adjusting, guiding and detachably securing cable linkages 26 may be used.
Referring to FIGURE 1~ chain hooks 36 are also provided to hook on to and hold upright first gate .L8 and second gate 22.
Referring to FIGURE ~, stops 37 are provided to cushion gate closure. Referring to FIGURE 3~ cable linkages 26 are adapted such that where a vehicle 38 enters first end 14 of ctrive-over gate 10, first gate 18 is in a hor_zontal position, whereas second gate 22 is in a vertical position. Inversely, referring to FIGURE ~4, where vehicle 38 exits second end 16 of drive-over gate 10, second gate 22 moves to a horio;ontal position as first gate 18 moves to a vertical position. It will be appreciated that vehicle 38 may also enter second end 16 with second gate 22 beginning in a horizontal position and exit first end 14 with first gate 18 moving to a hori~;ontal position as second gate 22 moves to a vertical position.
Referring to FIGURE 5, in the illustrated embodiment, end hook 34 (not shown) and chain hooks 36 are disengaged allowing both first gate 18 and second gate 22 to be in the horizontal position. Referring to FIGURE C, chain hooks 36 engage first gate 18 and second gate 22 causing both first gate 18 and second gate 22 to be in the vertical position.

Referring to FIGURES 3 and 4, where traffic moves from one area to another and security between the two areas is required, drive-over gate 10 is positioned such that when motor vehicle 38 drives through enclosure 12 ~~0 (first end 14 to second end 16 as illustrated), it forces second gate 22 into the horizontal position and causes cable linkage 26 to pull first gate 18 into the upright position behind motor vehicle 38, thereby securing passage between the two areas. When the vehicle returns, second gate 22 is in the horizontal position ready to receive vehicle 38 and the actuating of the gates happens in the opposite order:
first gate 18 moves to the horizontal position and second gate 22 is pulled to the vertical position as vehicle 38 drives in the opposite direction. Where large vehicles like a tractor and trailer are driven, dri~ae-over gate 10 may be sized to accommodate the desired traffic (approximately 36 feet in length). Referring to FIGURE 5, where security is not an issue and a free flow of trafvfic is desired, cable linkages 26 may be temporarily detached from one of first gate 18 or second gate 22 to position both gates in the horizontal position. Referring to FIGURE ~, where enclosure 12 is required to contain livestock o:r facilitate any other secured enclosure, each of chain hooks 36 may be secured such that first gate 18 and second gate 22 are both in the upright position. Referring to FIGURE. 1, in the event that cable linkages 26 stretch or otherwise come to be out of adjustment, turnbuckle 30 may be tightened to restore the desired tension in c<~ble linkages 26.
In the illustrated embodiment, bushings 32 are positioned to guide cable linkages 26 toward the other gate.
