20100260585 | FLUSH-MOUNTED VEHICLE RESTRAINTS - A vehicle restraint installed within a pit underneath a dock leveler of a loading dock platform includes a single actuator that both extends and raises a barrier into engagement with a vehicle's ICC bar. When the barrier is in a retracted, stored position, the barrier is underneath the dock leveler and behind a front face of the loading dock platform. To engage the vehicle's ICC bar, the single actuator extends to first push the barrier along a first track to an intermediate position. That same actuator then pushes the barrier along a second track to a raised, operative position where the barrier engages and captures the vehicle's ICC bar. A spring coupled to the actuator provides the barrier with freedom to float along the second track to accommodate similar incidental movement of the ICC bar as the vehicle is serviced at the dock. | 10-14-2010 |
20100260586 | WHEEL RESTRAINT SYSTEMS - A wheel restraint for restraining a vehicle at a loading dock includes a wheel chock suspended from a tether. The tether hangs from an overhead beam such that the wheel chock can be swung down and underneath the vehicle and placed directly in front of a wheel of the vehicle. A pin can be used to help hold the chock to an anchor that is fastened to a driveway of the loading dock. The orientation of the pin and the anchor holes in which the pin can be selectively inserted prevents the chock from tipping back and makes the restraint more tolerant of dirt, ice and other contaminants. In some examples, an offset between the beam and the wheel results in the tether urging the chock toward the anchor. | 10-14-2010 |

20110243694 | VEHICLE BRACES HAVING A TRACK-CLAMPING MECHANISM - An example of a vehicle brace for use at a loading dock includes a vehicle support member that can travel to various heights along a vertical track. The support member exerts a substantial but limited resistive force up against the underside of a vehicle's rear impact guard to mitigate bouncing of the vehicle's truck or trailer bed as the vehicle is being loaded and/or unloaded of its cargo. Of particular interest in some examples is a rather short brake actuator mounted at an angle to create an inclined binding clamp action, the actuator being installed to travel with the vehicle support member, and the track having an inclined braking surface so that the brake's clamping force does not rely on friction alone, all of which provides for a compact vehicle brace installable as a self-contained unit and operated without having to rely on structural support from a driveway surface. | 10-06-2011 |

20140064891 | VEHICLE RESTRAINTS WITH ANTI-ROTATION FEATURES - Example vehicle restraints having example anti-rotation features are disclosed herein. In some examples, an actuator in the form of a hydraulic cylinder moves both a vehicle barrier and its brace between stored and activated positions. If the vehicle pushes the barrier from an upper blocking position to an intermediate blocking position, the brace helps support the barrier at the intermediate blocking position to prevent the vehicle from further pushing the barrier to its stored position. To avoid damaging a cover plate or other relatively weak areas of a vehicle's RIG (rear impact guard), some example barriers disclosed herein exert a holding force that is less at the upper blocking position than at the intermediate blocking position. | 03-06-2014 |
20140064892 | VEHICLE RESTRAINTS WITH ROTATING AND TRANSLATING BARRIERS - Example vehicle restraints with rotating and translating barriers are disclosed herein. An example vehicle restraint disclosed herein a main body installable at a loading dock and a barrier to be coupled to the main body. The barrier rotates about an axis relative to the main body between an upper blocking position to block the RIG and a stored position to release the RIG, where for a given elevation of the main body the barrier being higher in the upper blocking position than in the stored position. The barrier moves radially with respect to the axis. | 03-06-2014 |
20140255134 | TRACK-MOUNTED WHEEL RESTRAINT SYSTEMS - Example manual wheel restraint systems and methods for restraining a vehicle at a loading dock include are disclosed herein. An example wheel restraint disclosed herein includes a retractable wheel-blocking barrier mounted to a carrier that can be repositioned along a track, where the track is anchored to a driveway of a loading dock. The track runs generally parallel to a vehicle path that a wheel of a vehicle travels along as the vehicle backs into the dock. To block a rear wheel of the vehicle parked at the dock, the barrier extends laterally into the wheel path, adjacent or in front of the wheel. To release the vehicle, the barrier retracts out from within the wheel path. In some examples, to ensure that the vehicle is secured, the barrier and/or the carrier include barrier or carrier catches to help hold the barrier and carrier in a fixed position. In some examples, one or more sensors determine or sense whether the catches are secured or released and generate signals accordingly. The signals, in some examples, alert dock personnel of the condition of the catches. | 09-11-2014 |
