摘要:
A retractable barrier system includes an example gear assembly that can be manipulated for rapidly deploying a flexible barrier, exerting high torque for the initial tightening of the barrier, maintaining high static tension in barrier when in use, and/or rapidly retracting barrier for storage. In some examples, the gear assembly is a worm drive with a worm that can be selectively disengaged from a worm gear. Other optional features of the barrier system include selective right-hand/left-hand configurations, an electric switch that can be added to indicate whether the barrier system is in use, an intermediate coupling that joins the distal ends of two barriers for creating an extra long barrier system, and removable vehicle-mounted posts for certain loading dock applications.

A dock leveler includes a vehicle-engaging pivotal lip extending from the front end of a pivotal deck, wherein the lip has one or more unique features that provide a smooth transition for forklifts traveling between the lip and a trailer bed upon which the lip is resting. The smooth transition minimizes jolting and vibration of the forklift and its driver as the forklift wheels pass over the leading edge of the lip. The special features of the lip may include one or more of the following: a curved traffic-bearing surface terminating at a sharp or blunt leading edge, a traffic-bearing surface that includes both flat and curved sections, a multifaceted traffic-bearing surface that approximates a curved surface, a rubber or plastic shock absorbing element, an articulated nose piece at the lip's leading edge, and a main lip plate that is coplanar with the deck's traffic surface (i.e., zero crown angle).

A kit for variably positioning an antenna housing (20) and a transmitter housing (18) in a subsurface enclosure (10) with a utility meter (15) and a meter register (16) includes a bracket (30) which is rotatable with the antenna housing (20) to a selected position within 360° of rotation, and then secured with fasteners (39) to the stem (22) of the antenna housing (20). The kit also includes a spacer (23) which is held between the top flange (31) of the bracket (30) and an underside of the pit lid (13). The bracket (30) also has a depending flange (32) for mounting the transmitter assembly (18) in a suspended position from the antenna housing (20) in either a horizontal or vertical orientation to better utilize available space in the pit enclosure (10).

Vehicle restraint systems are disclosed herein. An example vehicle restraint system includes a base to be positioned adjacent a loading dock and a wheel chock to be positioned on the base. An actuator is coupled to the base and moves the base relative to a wall of the loading dock in a linear direction between a release position and a holding position when the wheel chock is coupled to the base. In the release position, the wheel chock disengages from a wheel of a vehicle positioned at the loading dock. In the holding position, the wheel chock frictionally engages the wheel of the vehicle to restrict movement of the wheel away from the loading dock.

The subject invention relates to a method and a device for aiding users in determining the correct correspondence between infant clothing size and meteorological season, based on infant birth date. The method includes using an infant clothing sizing chart with a plurality of rows that correspond to an infant birth date and a plurality of rows that correspond to one of a meteorological season or an infant clothing size. The user cross-references a row and a column of interest to find a point, or cell, or intersection, wherein the point, or cell, of intersection indicates either the appropriate size or season for which infant clothing should be purchased. The subject device, on the other hand, receives user input related to the infant's birth date and one of the meteorological season or the infant clothing size, manipulates the inputted data, and outputs either the appropriate size or season for which infant clothing should be purchased.

A wheel restraint for restraining a vehicle at a loading dock includes various features such as, a wheel chock supported by a spring loaded articulated arm with a spring that can be selectively tightened or released, a sensor that detects whether the chock is solidly against a base plate or floor, a bi-directional pivotal joint between the articulated arm and the wheel chock to ensure that the chock can sit squarely on a mating base plate, a wheel chock that meshes with a hydraulically actuated base plate, pivotal or otherwise movable backstops that prevent a wheel chock from sliding out of position, and a base plate cleaning system. The cleaning system might include a vehicle-actuated brush, fluid spray nozzles, electric heater and removable cover plates.
