Barrier Gate With Torque Limiter
US Patent:
7818920, Oct 26, 2010
Filed:
Nov 6, 2007
Appl. No.:
11/982927
Inventors:
Lynn R. Causey - Russellville AL, US
Roger D. Causey - Russellville AL, US

International Classification:
E01F 13/00
US Classification:
49 49
Abstract:
Disclosed is an apparatus for a barrier gate designed to control vehicular travel through a passageway. The invention disclosed employs a barrier arm, a housing, a motor and transmission, a rotary encoder, and a torque limiter assembly. The torque limiter assembly comprises a hub, spindle, brake disk, rotor, and a gland nut. The torque limiter assembly is mounted to the motor and transmission as well as connected to the barrier arm. The torque limiter assembly provides sufficient friction to rotate the barrier arm and also protects the internal gears and linkages of the transmission and motor from costly repair/replacement by preventing any unwanted rotation. In the event an outside force rotates the barrier arm, the rotary encoder in cooperation with a controller instantly recognizes the position of the barrier arm and further acts as a limit switch to send a signal to the motor to stop when the barrier arm is in place.

Abstract:
Disclosed is an apparatus and method for decelerating moving vehicles. A set of two novel pylons is disclosed employing a simple, durable and reliable braking mechanism. Each braking mechanism comprises a spindle assembly including a brake disk and a spool assembly comprising a rotor and two caliper disks adjacent the brake disk. The spool assembly is pivotally mounted on the spindle assembly. As the strap is deployed a ratchet and pawl mechanism fixed to the base of the spindle assembly prevents the spindle assembly from rotating with respect to the spool assembly. The sliding friction between the caliper disks and the brake disk impedes the rotation of the spool assembly and restrains deployment of the strap. After impact, the strap can be rewound via a ratchet nut located on the spool assembly. During rewind the spindle assembly rotates with the spool assembly. An additional embodiment connects a sacrificial barrier between the two pylons mounted to a gantry.
