摘要： A wheel-activated vehicle restraint for use at a loading dock includes a wheel-blocking barrier that is selectively locked to a frame by a latching mechanism that engages an inverted gear rack. Components of the latching mechanism are arranged to prevent spreading apart upper and lower members of the frame members. The latching mechanism includes an alignment device that helps ensure that the teeth of a latching member positively engages the teeth of the gear rack, thus preventing the teeth from coming together peak-to-peak. An upper rail of the wheel restraint's frame includes a contoured leading edge that smoothly guides the lift of the wheel-blocking barrier from its stored position to its wheel-chocking position. A wheel support is used to prevent a vehicle's mud flap from getting pinched between the vehicle's wheel and a trigger assembly of the wheel restraint.

摘要： A dock leveler includes a pivotally extendable lip coupled to a pivotal deck by way of a front hinge, wherein the structure in the area of the front hinge optimizes the torsional flexibility of the deck; provides a well supported, durable crown (apex angle between an extended lip and the deck); and reduces the part count of the dock leveler. The front hinge includes a deck-hinge member that extends approximately the full width of the deck and is preferably formed from a single sheet of material. A particularly narrow front header or flange disposed along the front edge of the deck reinforces the relatively thin deck plate so that the plate's rigidity more closely matches that of the thicker lip, yet the flange is sufficiently small to allow the deck to twist so that the deck can place the tip of the lip squarely upon a sideways inclined truck bed.

摘要： A truck leveler includes a low-profile traffic surface that is pivotally mounted to a driveway approach in front of a loading dock. Pivoting the leveler raises a reat portion of a truck or trailer to the height of the dock. The truck leveler has strength, rigidity and accommodates a retractable or repositionable wheel restraint while maintaining its low profile. This is accomplished by virtue of a raised rear beam and two lateral beams that extend above the traffic surface of the leveler. A central beam allows field assembly of the leveler while adding further to the leveler's strength and rigidity.

摘要： A dock leveler for a truck loading dock includes a pivotal deck that is actuated by an inflatable column assembly. The inflatable column assembly includes a pliable tube that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The shape and orientation of the column assembly is such that the lengths of the pliable tube's seams are minimized. A pliable fabric sheet held in tension against the underside of the deck provides a generally flat, broad surface against which the pliable tube can push as the inflatable column assembly pushes the deck upward. A footed pallet underneath the pliable tube can be banded to the deck during shipment. After installation, the pallet can be readily lifted for cleaning the pit floor underneath the pallet.

摘要： An apparatus and related method for a dock housing for a pre-existing loading dock. The dock housing includes a base with top and a bottom surfaces and front, back and opposed sidewalls. The front wall has integral fork pockets for interaction with forks on a fork truck for movement of the base into a desired location and the top surface has an opening to receive a dock leveler into such opening. Also included is a modular frame mounted onto the base in sections, the sections including a frame-front wall, opposed frame-sidewalls and a frame-top wall, the frame-front wall having a trailer-receiving opening to receive a trailer, the frame-sidewalls including a slotted-base attachment for securement of the base and sidewalls together. The dock housing is formed by securing the frame-sidewalls to a wall of a pre-existing building as well as securing the base, the frame-front wall and the frame-top wall together.
