    Abstract: Example dock levelers at a truck-loading platform include a stationary curved transition plate extending between a rear edge of the leveler's pivotal deck and a rear edge of a pit at which the leveler is installed. The transition plate has a curved portion that extends underneath the deck's rear edge. The plate provides a smooth transition for forklifts traveling between the platform and the deck, thus reducing and/or minimizing the jarring of the forklift and its driver. To prevent debris and obstructions from getting trapped within the deck's rear hinge, the rear edge of the deck rises up and over the transition plate as the deck pivots upward, thereby providing a self-cleaning effect. With the rear edge of an inclined deck being above the transition plate, water runoff from the deck drains onto the transition plate rather than through the hinge gap to a generally inaccessible area underneath the deck.

  • Patent number: 8075409
    Abstract: A fencing strip includes a plurality of light assemblies, in communication with the scoring controller and console. The light assemblies are embedded at predetermined locations within the fencing strip to project at least two different types of light through the perforations, indicating which fencer has scored. The light assemblies are located at spaced-apart positions along the overall length of the strip which includes an electrically conductive top surface that completes a circuit when a fencer's conductive blade contacts the strip surface (a non-scoring touch). The conductive top surface is perforated to maintain a continuous contact surface that can differentiate a non-scoring touch from a fencer's blade, via an interconnection between the top surface and scoring console. The perforations allow for transmission of light therethrough. A plurality of ramped placards extend outwardly from the overhang of the elevated subsurface and the adjacent floor in a downwardly angled direction.

  • Publication number: 20100146719
    Abstract: A safety system for a truck loading dock with an elevated platform provides an alarm that warns of a hazard at the loading dock such as a forklift operating inside the truck or a falling hazard that may exist due to the dock door being open while a truck is not present at the dock. In cases where a dock's open doorway is protected by a barrier that can be opened or closed, the alarm can be de-activated by closing the barrier. In some examples, the safety system includes a remote body sensor that detects when someone or something is near the doorway. In response to the body sensor, a second, more pronounced alarm can warn of more imminent danger where someone on the platform may be too close to an open doorway when a truck is not present.

  • Publication number: 20100031457
    Abstract: A dock leveler with a deck and an extendable lip that hangs pendant when the deck is in a stored position. A lip extension mechanism engages when the deck is raised to a raised or cocked position. As the deck is lowered to an intermediate transition position, the extension mechanism extends the lip to a fully extended position. At the transition position, the lip extension mechanism automatically disengages and a lip locking mechanism automatically and simultaneously locks and holds the lip in its fully extended position. When the deck is further lowered so that the lip comes to rest on a truck trailer, the locking mechanism automatically released or unlocked. The lip returns to its pendant position when the deck is raised from the truck bed. After the truck pulls away from the dock, the deck is lowered to its stored position.

  • Publication number: 20090304480
    Abstract: In a watercraft storage system a “wishbone” or U-shaped cradle liftable and rotatable by an overhead crane comprises adjustable air filled hull supports to either side of a boat hull and a keel support toward the stem of the watercraft. The cradle central opening clears a cantilever storage rack support beam assembly allowing the watercraft lo be lowered onto or raised from the cantilever storage rack support beam assembly by an overhead traveling crane. To substantially reduce any longitudinal swaying of the cradle and watercraft during raising and lowering, a system or diagonal anti-sway bracing cables that automatically retract and extend is employed. In the preferred embodiment, the cradle is lowered into a water-filled channel within the storage structure to re-float the watercraft. A watercraft to be stored can be brought into the channel which contains alignment means to accurately position the watercraft over the cradle.

  • Publication number: 20090205146
    Abstract: 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.

  • Patent number: 7564367
    Abstract: Disclosed is an electromechanical system for minimizing passenger door contact with the Passenger Loading Bridge (PLB) floor and subsequent damage to said door, during passenger loading or off loading. The system, as configured at the Cab entry, senses the proximity of the aircraft door by contacting a sensing pad, attached to the PLB floor. This initiates a sequence of events. 1) Both visual and auditory alarms are initiated to alert the passenger loading agents and/or the bridge operator of a fault. 2) The PLB is moved down and away from the door sufficiently to prevent the PLB floor from coming in contact with the door. The loading agents or PLB operator can then perform the necessary steps to reset the device and continue loading.
