  • Patent number: 9776511
    Abstract: Example vehicle alignment systems for use at loading docks are disclosed herein. An example vehicle alignment system includes a sensor system to detect a surface of a vehicle, where the sensor system obtains a feedback signal representative of a spatial orientation of the detected surface relative to a reference as the vehicle approaches a doorway of the loading dock. A controller detects a threshold deviation in the spatial orientation of the detected surface of the vehicle relative to the reference based on the feedback signal. A display varies an output signal in response to the detected deviation in the spatial orientation of the detected surface relative to the reference.

  • Patent number: 8915029
    Abstract: Example flexible face panels for dock shelters and dock seals at a loading dock include a tip seal and/or an air-filled blister or elongate “bubble” that sealingly conforms to a rear portion of a vehicle (e.g., truck, trailer, etc.) at the dock. In some examples, an air chamber within the blister is open at one or both ends. This prevents otherwise trapped pressurized air from adversely affecting the blister's compliance or its ability to sealingly conform to irregular surfaces of the vehicle. In some examples, as the vehicle backs into and deflects the face panel, the blister distorts and wraps itself around the vehicle's surface irregularities, such as door hardware and protruding lights. In some examples, the face panel's tip seal includes an overlapping seal flap, wherein a series of slits in the tip seal allow the seal to fit over the vehicle's various surface irregularities.

  • Patent number: 8424254
    Abstract: This loading bay comprises a compact structure carrying at least one fold-away ramp and a shelter for closing off the space between the shed and the truck box body at the side and at the top during loading or unloading operations. Said compact structure adjoins the wall (P) of the shed on the outside and is set up with the possibility of being removed longitudinally on guide means for positioning the movable assembly in a position opposite any one of the openings (H) providing access to the shed. The loading bay comprises, additionally, motorized actuating means, at least one bar of sensors for detecting the position of the truck while said truck is being moved closer into position, a light-signalling device and a light and/or acoustic signal warning of the approach of a truck.

  • Publication number: 20130047526
    Abstract: Head curtains for dock shelters or dock seals are disclosed. An example dock apparatus disclosed herein includes a first weather barrier and a second weather barrier. The first and second weather barriers are positioned laterally of a doorway of a loading dock and compressible by a vehicle. The lateral weather barriers include inner surfaces that are to bulge toward each other in response to the vehicle compressing the lateral weather barriers. A head curtain is at least partially positioned between the lateral weather barriers and being engagable by the vehicle, the head curtain having a lateral stiffness such that in response to the vehicle engaging the head curtain and compressing the lateral weather barriers, the head curtain becomes pinched between the bulging inner surfaces to restrict a vertical movement of the curtain.

  • Publication number: 20130031853
    Abstract: Flexible structures for use with dock seals and shelters are disclosed. An example flexible structure includes a rigid backer to couple a flexible panel assembly to a loading dock wall and a flexible, self-supporting sheet-shaped member having sufficient rigidity to enable the flexible sheet-shaped member to be cantilevered from a surface of a building without substantial sagging. The sheet-shaped member has an inner surface and an outer surface defining a first longitudinal edge and a second longitudinal edge where the first and second longitudinal edges couple to the rigid backer. The inner surface defines an empty cavity when the sheet-shaped member is coupled to the rigid backer.

  • Patent number: 8181759
    Abstract: A bumper for use at a loading dock has two ranges of front-to-back movement: one range for sealing the gap that might otherwise exist between the rear edge of a truck and the front face of the bumper and a second range for absorbing the impact of the truck backing into the dock. In some cases, a spring provides a relatively light sealing force between the bumper and the truck, and a compressible core provides a much greater impact-absorbing force that helps stop the rearward movement of the truck. In some embodiments, the bumper pivots by gravity when operating in the sealing range.

  • Patent number: 8181401
    Abstract: Apparatuses for forming at least a partial seal between an open end of a truck, trailer, or other vehicle and an opening in a building are disclosed herein. In one embodiment, an apparatus for forming at least a partial seal includes a first side pad configured to extend vertically adjacent to a first side portion of an opening, a second side pad configured to extend vertically adjacent to a second side portion of the opening, and a head pad assembly configured to extend horizontally adjacent to a top portion of the opening between the first and second side pads. The head pad assembly can include replaceable corner pads positioned on either end of a center pad. The corner pads can be independently attached to the wall of the building and separately removed if replacement is needed.

  • Patent number: 8141305
    Abstract: Side seal member for a loading dock seal are disclosed. An example truck loading dock seal comprising a resiliently compressible side pad supported by a relatively rigid backer and encased within a pliable cover includes at least one flexible lip protruding from the cover to seal a gap that might exist between the backer and the wall to which the backer is mounted. In some cases, the lip is part of the cover and is located where a rear vertical edge of the side pad meets the wall. The flexibility of the lip enables the lip to sealingly conform to a wall having an irregular surface. For additional sealing, a back sheet of the pliable cover includes a touch-and-hold fastener and/or overlapping layers of material that can provide a compressible seal between the wall and the backer.

  • Patent number: 8112948
    Abstract: The present invention provides a sealing structure for a loading dock opening, consisting of two flexible side seals on opposite sides with a sealing form and mounted in a vertical orientation to a frame, and a curtain-like head seal also affixed to the frame, which is affixed to the loading dock walls. Taken together, the sealing structure sealingly engages the cargo body such that weather elements do not enter the warehouse or truck body but goods can be moved between the cargo body and the warehouse. The seal is deformable but resilient, forming a seal when in contact with the truck cargo body, which has shape memory and stiffness to revert to its original form when it no longer contacts the truck cargo body. The present invention also provides in one embodiment of the present invention, side seals mounted in a vertical orientation on each side of the loading dock entrance, an outer layer forming a sealing shape, typically that of a teardrop, in profile.
