  • Patent number: 9969576
    Abstract: Inflatable weather barriers for loading docks are disclosed. An example weather barrier includes an upper bellows defining a header air chamber between a top portion and a bottom portion of the upper bellows. A blower is in fluid communication with the header air chamber and the blower is selectively activated to discharge a pressurized air into the header air chamber to urge the upper bellows from a raised position toward a lowered position. The weather barrier includes a first extension spring that is under a first extension spring tension, a first pulley, and a first elongate member that is pliable. The first elongate member is under a first elongate member tension that urges the upper bellows toward the raised position.

  • Patent number: 9751703
    Abstract: Seal assemblies for dock shelters and dock seals at a loading dock are disclosed herein. An example seal assembly includes a foam pad, a pliable cover to couple to the foam pad, and a shield to attach to the foam pad. The shield has a first end and a second end. The first end is to couple to at least one of the foam pad or the pliable cover and the second end is to project adjacent a vehicle-engaging surface of the foam pad. The shield is to move relative to the foam pad between a standby position when a vehicle is in a non-engaging relationship with the vehicle-engaging surface and a deflected position when the vehicle is in engagement with the vehicle-engaging surface.

  • Patent number: 9079713
    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.

  • Patent number: 8943630
    Abstract: A dock leveler comprising a vehicle-engaging lip pivotally coupled to the vertically adjustable front edge of a deck includes a seal or series of seal segments that close one or more air gaps that exist in the area where the lip is hinged to the deck. Such gaps are particularly large when the lip hinge comprises a hinge pin that couples a series of lugs extending from underneath the deck to a series of lugs extending from the lip, wherein the lugs are spaced apart along the length of the hinge pin. The seal or seal segments could be above the deck, below the deck, or interposed between the adjoining edges of the deck and the lip. In some cases, the seal is provided by an air curtain or by a tube that is inflatable or hermetically sealed.

  • 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: 8887447
    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.

  • Publication number: 20140026359
    Abstract: Example trolleys and hangers for washdown curtains are disclosed herein. An example trolley disclosed herein includes features that simplify manufacturing and promote liquid runoff to avoid bacterial growth. Some example trolleys comprise U-bolts, shoulder screws and acorn nuts. In some examples, a frame of the trolley has a nestable V-shape profile that makes the frame readily blanked and formed from sheet metal with minimal waste. In some examples, an example trolley disclosed herein has a pair of rollers that are horizontally offset to a point from which the curtain hangs so that the weight of the curtain tilts the trolley to promote liquid runoff from the trolley's frame.
