20100269427 | HEAD CURTAINS FOR DOCK SHELTERS OR DOCK SEALS - Head curtains for dock shelters or dock seals are disclosed. An example head curtain assembly for a vehicle loading dock includes a retractable curtain stiffened by a resiliently compressible foam panel that is more flexible about a horizontal axis than about a vertical axis. The difference in directional flexibility can be created by sewing the foam panel to a pliable cover using a series of parallel horizontal thread lines. The thread lines create in the foam a series of compressed indentations that run horizontally across the curtain so that the curtain tends to bend more easily along those lines. The relative stiffness in the horizontal direction enables the curtain to exert an appreciable sealing force against two lateral dock seal members, and the vertical flexibility makes the curtain easy to retract to accommodate vehicles of various heights. Touch-and-hold fasteners make many of the individual components of the head curtain readily replaceable. | 10-28-2010 |
20130047526 | HEAD CURTAINS FOR DOCK SHELTERS OR DOCK SEALS - 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. | 02-28-2013 |
20130221624 | FACE PANELS FOR LOADING DOCK SEALS AND SHELTERS - 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. | 08-29-2013 |
20130239494 | HEAD CURTAINS FOR DOCK SHELTERS OR DOCK SEALS - 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. | 09-19-2013 |
20150007509 | VEHICLE-ACTUATED WEATHER BARRIER APPARATUS - 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. | 01-08-2015 |
20150007510 | Loading Dock Weather Barrier Apparatus - 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. | 01-08-2015 |
20150007511 | WEATHER BARRIER APPARATUSES FOR SEALING OR SHELTERING VEHICLES AT LOADING DOCKS - Example weather barrier apparatuses for sealing or sheltering vehicles at loading docks are disclosed herein. An example apparatus includes a side seal member to be vertically elongate and having a front surface facing away from a doorway when the apparatus is in a relaxed configuration, the side seal member extending laterally farther into a cargo passageway when the apparatus is in the relaxed configuration than when in an activated configuration, the front surface engages a vehicle as the vehicle moves between a departed position and a parked position. The apparatus also includes an upper seal member to hang in front of the side seal member when the apparatus is in the relaxed configuration, the upper seal member being horizontally elongate and having a lower corner point proximate the side seal member, the front surface facing away from the lower corner point when the apparatus is in the activated configuration. | 01-08-2015 |
