Abstract

A crossing gate mechanism includes an enclosure housing multiple electric and electronic components with a control unit configured to operate the crossing gate mechanism and associated crossing gate arm, a cover for opening and closing the enclosure, wherein the cover is moveable between a closed position and an open position, wherein the enclosure houses a sensing device, wherein the cover includes a detectable device, and wherein the detectable device is arranged in the cover such that, when the cover is moved into the closed position, the detectable device comes in proximity to the at least one sensing device, and the sensing device is configured to indicate that the cover is in the closed position.

First claim

The invention claimed is:

1 . A crossing gate mechanism comprising:
an enclosure housing multiple electric and electronic components including a control unit configured to operate the crossing gate mechanism and associated crossing gate arm, a cover for opening and closing the enclosure, wherein the cover is moveable between a closed position and an open position, wherein the enclosure houses at least one sensing device comprising a Hall sensor array, wherein the cover comprises a detectable device comprising a magnetized bolt having a magnetized area in a head of the bolt, and wherein the detectable device is arranged in the cover such that, when the cover is moved into the closed position, the detectable device comes in proximity to the at least one sensing device with an adjustable space therebetween, and the at least one sensing device is configured to indicate that the cover is in the closed position, and wherein the control unit is configured to generate and output a signal indicating that the cover is in the closed position when the Hall sensor array detects the magnetized area.

2 . The crossing gate mechanism of claim 1 ,
wherein the control unit comprises a printed circuit board (PCB), and wherein the Hall sensor array is arranged on the PCB, and wherein an active area of the Hall sensor array is greater than the magnetized area of the bolt.

3 . The crossing gate mechanism of claim 1 ,
wherein the magnetized bolt or pin comprises a circular magnet with a diameter, the magnet being arranged in a head of the bolt or pin.

4 . The crossing gate mechanism of claim 1 ,
wherein the cover comprises a threaded mounting hole for receiving the detectable device.

5 . The crossing gate mechanism of claim 4 ,
wherein the detectable device is securely mounted in the threaded mounting hole via a jam nut.

6 . The crossing gate mechanism of claim 1 , comprising:
a transmitter configured to transmit the signal that the cover is in the closed position to another system or device.

7 . The crossing gate mechanism of claim 6 ,
wherein the transmitter is configured to wirelessly transmit the signal to the other system or device.

8 . The crossing gate mechanism of claim 1 , comprising:
a display and/or multiple light emitting diodes (LEDs), wherein the control unit is configured to turn off the display and/or the LEDs when the cover is in the closed position to conserve power.

9 . The crossing gate mechanism of claim 1 ,
further configured to maintain the cover in the closed position and disable access to the crossing gate mechanism.

10 . The crossing gate mechanism of claim 9 ,
wherein the control unit is configured to disable and enable the access based on a received communication signal.

11 . The crossing gate mechanism of claim 10 ,
wherein the communication signal comprises a Bluetooth® signal.

12 . A crossing gate system comprising:
one or more crossing gate arm(s), and a crossing gate mechanism comprising:
an enclosure housing multiple electric and electronic components including a control unit configured to operate the crossing gate mechanism and associated crossing gate arm,
a cover for opening and closing the enclosure, wherein the cover is moveable between a closed position and an open position,
wherein the enclosure houses at least one sensing device comprising a Hall sensor array,
wherein the cover comprises a detectable device comprising a magnetized bolt having a magnetized area in a head of the bolt, and
wherein the detectable device is arranged in the cover such that, when the cover is moved into the closed position, the detectable device comes in proximity to the at least one sensing device with an adjustable space therebetween, and the at least one sensing device is configured to indicate that the cover is in the closed position, and
wherein the control unit is configured to generate and output a signal indicating that the cover is in the closed position when the Hall sensor array detects the magnetized area.
