The seal includes an outer flexible sheet having a first end and a second end. The seal includes an inner flexible sheet having a third end and a fourth end. The third end of the inner flexible sheet couples to the first end of the outer flexible sheet and the fourth end of the inner flexible sheet couples to the second end of the outer flexible sheet. The inner flexible sheet provides an edge seal and a surface seal. The edge seal engages a rearward facing edge of a vehicle and the surface seal engages surface panel of the vehicle when the vehicle is in engagement with the seal. A guide movably couples the outer flexible sheet and the inner flexible sheet. The guide is positioned between the respective ends of the inner and outer flexible sheets. The guide spaces apart a portion of the inner flexible sheet from a portion of the outer flexible sheet. The inner flexible sheet, the outer flexible sheet and the guide are to move between a first position and a second position in response to a force imparted to the weather barrier by the vehicle when the vehicle is in engagement with the inner flexible sheet to enable at least one of the edge seal to conform to a shape of the rearward facing edge of the vehicle or the surface seal to conform to a shape of the surface panel of the vehicle.

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.

Face panels for loading dock seals and shelters

Example lateral sealing members for use with weather barriers are disclosed. An example lateral sealing member includes a lateral sealing member being vertically elongate. The lateral sealing member has a J-shaped cross-section extending between an attached end and a tip of the lateral sealing member. The lateral sealing member has a groove along the tip. The lateral sealing member is movable between an activated configuration and a relaxed configuration. The tip to extend farther into a vehicle pathway when the lateral sealing member is in the relaxed configuration than when the lateral sealing member is in the activated configuration. A tip seal is provided along the tip of the lateral sealing member. The tip seal is to protrude in the groove.

Sealing members for weather barriers

Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus includes a curtain having a plurality of compressible tubes positioned between a first end of the curtain and a second end of the curtain. The compressible tubes move between a collapsed position when the curtain is in a relaxed condition and an expanded position when the curtain is a taut condition.

Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus disclosed herein include rear edge seals to sealingly engage a rearward facing edge of a vehicle parked at a loading dock. In some examples, the rear edge seal is part of a pivotal upper or side seal member that also includes a surface seal. The surface seal is spaced apart from the edge seal and is to sealingly engage a side or upper surface of the vehicle. In some examples, the vehicle's side surface is the outward facing surface of the vehicle's swung-open door. In some examples, the vehicle backing against the edge seal is what deploys the side seal. Some example weather barrier apparatus disclosed herein include an upper seal member and two side seal members, where vehicle-activated movement of the upper seal and side seal members are coordinated to seek and seal against rear corners of a cargo opening of the vehicle. In some examples, one or more seal members lengthen in response to the size and position of the vehicle.

Head curtains for dock shelters or dock seals are disclosed. An example dock apparatus disclosed herein includes a curtain to be suspended from a support panel and configured to be engaged by the vehicle. The curtain has a plurality of pleats overlapping a plurality of loops such that the plurality of loops is positioned between a vehicle-engaging surface of the curtain and the plurality of pleats.

Head curtains for dock shelters or dock seals

Example flexible face panels for dock shelters and dock seals at a loading dock are disclosed herein. An example seal assembly comprises a face panel to be coupled to a projection panel, where the face panel has a front side, a back side and an edge spaced apart from the projection panel. A bulb is positioned adjacent the edge of the face panel. A seal flap is attached to the bulb such that the seal flap projects from an outer surface of the bulb and toward a doorway of a loading dock when the seal assembly is coupled to a wall of the loading dock.

Example weather barrier apparatuses disclosed herein include vehicle-actuated mechanisms for forcibly pressing a seal member down against a roof of a vehicle parked at a loading dock. In some examples, rather than relying on gravity alone, rearward movement of the vehicle mechanically expands a seal member to create sufficient reach and sealing pressure to press the expandable seal member firmly against vehicle roofs of various heights and positions. In some examples, an example vehicle-actuated mechanism disclosed herein forces a compressible seal down against the vehicle's roof and maintains a compressive sealing force over a range of roof heights and positions. Some example weather barrier apparatuses disclosed herein include example means for mitigating certain jam conditions.

Loading dock weather barrier apparatus

Example flexible face panels for dock shelters and dock seals at a loading dock are disclosed. An example seal assembly includes a projection panel mountable to extend outward from the wall in proximity with a doorway. A first face panel extends from the projection panel in front of the doorway when the projection panel is mounted to the wall, where the first face panel has a first distal edge spaced apart from the projection panel. A second face panel extends from the projection panel in front of the doorway when the projection panel is mounted to the wall, where the second face panel having a second distal edge spaced apart from the projection panel.

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.
