Abstract
A dock seal, such as a head seal mountable above a doorway of a loading dock, includes a compressible body with a support panel. The compressible body can conformably seal against the rear edge of a vehicle's enclosed trailer as the vehicle backs the trailer up against the seal. The support panel provides relatively dense structure for mounting the seal to the wall of a building. Compared to the horizontal distance that the compressible body projects from the wall, the support panel is ultra-thin to avoid consuming compressible space between the wall and the rear of the trailer. In some cases, a flexible panel suspends the compressible body and its support panel from the wall such that the flexible panel allows the dock seal to move relative to the wall.
Description
- The subject disclosure generally pertains to loading dock seals and more specifically to a unique support panel for such a seal.
- When an exterior doorway of a building is used as a loading dock for vehicles, such as trucks and tractor/trailers, the perimeter of the doorway often includes a dock seal. Dock seals close off gaps that would otherwise exist between the exterior face of the building and the back end of the trailer. Dock seals allow cargo from the rear of the trailer to be loaded or unloaded while dockworkers and the cargo are protected from the weather. Usually two side seals run vertically along the lateral edges of the doorway, and a top or head seal runs horizontally along the doorway's upper edge; however, additional seals can also be used.
- A typical dock seal comprises a resiliently compressible foam core supported by a rigid backer, such as a wood plank or a formed metal plate. The foam core and backer are normally encased within a fabric outer cover. Sealing is provided by backing the trailer up against the seal so that the seal compressively conforms to the rear shape of the trailer. The foam core provides the necessary compliance and resilience to repeatedly conform to the shape of various trailers; the outer cover protects the foam core from dirt, water and wear; and the backer provides solid structure for mounting the seal to the wall and for supporting the foam core so that the foam core does not twist and roll within the fabric cover.
- Due to the trailer's wheel suspension, adding or removing cargo and/or driving a forklift on and off the trailer bed can cause the rear of the trailer to repeatedly rise and lower a few inches. Although the incidental movement can be a problem, most dock seals are sufficiently wear resistant to tolerate such movement.
- A more serious problem, however, can occur after a tractor backs its trailer up against the dock seal, and the trailer is subsequently unhitched from the tractor while the trailer is still up against the seal. The front end of the unhitched trailer might then be set back down on the trailer's landing gear or temporarily rehitched onto a special tractor (yard jockey or yard mule) designated specifically for shuffling trailers around the loading dock area. Hitching and unhitching the front end of the trailer can cause the entire trailer to tilt about its rear wheels. The resulting seesaw action produces substantial up and down movement at the rear end of the trailer, which can cut and abrade the dock seal.
- Moreover, when the front end of the trailer is raised, which tilts the rear end of the trailer downward, the upper rear edge of the trailer can dig deeply into the dock's head seal. When the front end of the trailer is subsequently lowered, the trailer's rear edge can pry the head seal upward.
- In some cases, the trailer's rear edge digs into the seal so deeply that the edge catches the seal's backer and pries the head seal off the wall. This particularly tends to happen with relatively thick backers that are made intentionally thick to provide the foam core with ample support. If the backer is too thin, however, or omitted entirely in order to prevent the trailer's rear edge from catching the backer, the foam core may tend to roll and twist within the outer fabric cover. Thus, it can be difficult to design a backer with a thickness that addresses both problems.
- In some embodiments, a dock seal comprises a compressible body reinforced by an ultra-thin support panel.
- In some embodiments, the thickness of the support panel is less than 2% of the compressible body's thickness.
- In some embodiments, the thickness of the support panel is 0.5-1.5% of the compressible body's thickness.
- In some embodiments, the support panel is a substantially flat piece rather than a formed sheet metal pan with flanges. As a flat piece, the support panel's material thickness is substantially equal to its panel projection, which maximizes the compressible projection of the dock seal.
- In some embodiments, a flexible panel couples a dock seal and its support panel to a wall such that the flexible panel allows the seal and its support panel to move relative to the wall, wherein the movement is in a direction that is generally perpendicular to the seal's length.
- In some embodiments, a support panel is embedded within a compressible body so that the support panel can be readily bonded in place.
- In some embodiments, a dock seal includes a front compressible body for sealing against a vehicle and a rear compressible body for sealing against a building wall.
- In some embodiments, the compressible body of a dock seal comprises a collapsible frame supporting a pliable cover.
- In some embodiments, the support panel of a compressible body includes a series of holes that facilitates bonding the panel in place.
- In some embodiments, a dock seal includes a front compressible body for sealing against a vehicle, a rear compressible body for sealing against a building wall, and an intermediate compressible body that helps in bonding a support panel and the rear compressible body to the front compressible body.
- In some embodiments, the dock seal includes a compressible body and a support panel, wherein the relative densities and relative projections of the body and the panel are within a specific novel range such that the dock seal is particularly tolerant of deep gouging and prying by a vehicle pressing up against the seal.

FIGS. 1 and 3 show avehicle 10, such as a trailer of a truck, backing up to aloading dock 12. Loadingdock 12 is basically adoorway 14 or an opening in awall 16 of a building and may be associated with adock leveler 18, bumpers, and other items that facilitate loading and unloading of the vehicle's cargo. One such item in particular, which is the subject of this disclosure, is acompressible dock seal 20.Dock seal 20 may comprise ahead seal 22 and/or twolateral seals 24, which are shown in a relaxed position inFIGS. 1 and 3 . - When
vehicle 10 is backed up againstdock seal 20, as shown inFIGS. 2 and 4 ,head seal 22 andlateral seals 24 can help close the air gap that might otherwise exist between the outer face ofwall 16 and anupper edge 26 andlateral edges 28 of the rear ofvehicle 10. Although much of the gap near a lowerrear edge 30 ofvehicle 10 is usually blocked off by an extendable lip ofdock leveler 18, it is conceivable fordock seal 20 to also include alower seal 32 for more complete sealing. - It is not unusual for
vehicle 10 to press itsrear edges dock seal 20. If these edges subsequently move up and down due tovehicle 10 being loaded and unloaded of cargo, or the vehicle's trailer tilts due to the front end of the trailer being hitched or unhitched, then the trailers'rear edges seal 20. In some cases, the vehicle's upperrear edge 26 might pryhead seal 22 upward from its position ofFIG. 4 to a pried-up position ofFIG. 5 . This is a common occurrence when using a yard jockey at a loading dock. - With a yard jockey, a typical operating sequence would be: 1) a yard jockey lifting the front end of the trailer (thus lowering the trailer's rear edge); 2) the yard jockey forcing the trailer's upper rear edge deeply into the dock's head seal (
FIG. 4 ); and 3) the yard jockey subsequently lowering the front end of the trailer down upon the trailer's landing gear. As the front end of the trailer descends, the trailer's upper rear edge pries the head seal upward (FIG. 5 ). - To prevent
damaging seal 20 under such conditions,head seal 22, lateral seals 24, and/orlower seal 32 can be of a construction that tolerates extreme compression, translation, rotation and/or distortion. This can be accomplished by supportingdock seal 20 with something other than a conventional backer; which is usually relatively thick and consumes volume that could otherwise be used for resilient compression and distortion. If a conventional backer of standard thickness were used to support the compressible portion of the seal, there is less room available for compression. In some cases, the support member is fastened to wall 16 with structure that allows some relative movement betweenseal 20 andwall 16. Although an example will be described with reference tohead seal 22, the same seal design may also apply tolateral seals 24 and perhapslower seal 32. - Referring to
FIGS. 3-6 ,head seal 22 comprises acompressible body 36, encased within a flexibleprotective cover 38. The term, “compressible body” refers to any structure than can resiliently return to its normally expanded shape after being compacted by an external force, such as the force exerted byvehicle 10. Examples ofcompressible body 36 include, but are not limited to, a foam block or a collapsible mechanism. In a current example,compressible body 36 comprises a frontcompressible body 40 and a rearcompressible body 42. Alternatively,compressible body 36 may comprise only frontcompressible body 40 with rearcompressible body 42 being omitted. Rearcompressible body 42, however, can improve the sealing betweenhead seal 22 and the face ofwall 16. Rearcompressible body 42 might also help in fastening asupport panel 44 to frontcompressible body 40, whereinsupport panel 44 provides suitable structure for fasteninghead seal 20 towall 16. - Although the actual design of
head seal 22 may vary, in a current example,support panel 44 is sandwiched betweencompressible bodies FIG. 6 , adhesive 46bonds bodies bodies holes 48 inpanel 44 and in anarea 50 surrounding anouter perimeter 52 ofsupport panel 44.Adhesive 46 may also provide some bonding directly betweensupport panel 44 and the facing surfaces ofcompressible bodies - Even though it is conceivable and well within the scope of the disclosure to bond or otherwise attach
support panel 44 directly tocompressible body 40 and omitcompressible body 42, such a design does not work quite as well as havingsupport panel 44 interposed between two bondable bodies. Ifcompressible body 40 is not firmly attached to support panel 44 (due tobody 42 being omitted, due to the support panel being too pliable, and/or due topanel 44 andbody 40 being of different materials that are not readily bonded by a common adhesive),compressible body 40 might move relative topanel 44 and roll withincover 38. With the addition ofcompressible body 42, it has been found thatbodies support panel 44. - In a current example,
compressible bodies Cover 38 can be any appropriate material including, but not be limited to, HYPALON, canvas duck, rubber impregnated fabric and coated nylon fabric.Support panel 44 can be made of metal, plastic or some other material that is substantially thinner and denser than frontcompressible body 36. - To mount
head seal 22 to wall 16, anysuitable fastener 54 can be used to fastensupport panel 44 directly to the face ofwall 16 or used to fastensupport panel 44 to one or moreflexible panels 56, which in turn are mounted to wall 16 via anotherfastener 58. Whenvehicle 10 pries upward againstseal 22, as shown inFIG. 5 ,flexible panel 56 allowsseal 22 to pivot or move relative towall 16.Flexible panel 56 can be made of any appropriately flexible material including, but not limited to, ⅛-inch HMW polyethylene. - To maximize the compressibility of
head seal 22,support panel 44 is much thinner than frontcompressible body 40. When in the relaxed state ofFIG. 3 , frontcompressible body 40 has aforward surface 60 and arear surface 62 that define acompressible projection 64 therebetween.Support panel 44 has a thickness orpanel projection 66 defined by the distance between aforward-most point 68 and arearward-most point 70 onpanel 44. To providehead seal 22 with extreme compressibility, seal 22 should have a projection ratio of less than 2%, wherein the projection ratio is defined aspanel projection 66 divided bycompressible projection 64. Best results are achieved when the projection ratio is between 0.5% and 1.5%. - Also,
head seal 22 may have a density ratio of less than 3%, wherein the density ratio is defined as density of frontcompressible body 40 divided by the material density ofsupport panel 44. Even better results are achieved when the density ratio is less than 1%. For an optimum combination of the projection ratio and the density ratio, the density ratio is may be less than the projection ratio. For a current example,compressible projection 64 is about 8 to 23 inches,panel projection 66 is about ⅛ inch,front body 40 has a density of about 1.5 pounds per cubic foot (24 kg/m3), andsupport panel 44 has a material density of about 480 pounds per cubic foot when made of steel or about 58 pounds per cubic foot when made of HMW polyethylene. - To facilitate manufacturability, a slightly modified
head seal 72 can be made as shown inFIG. 7 . In this case, seal 72 includes an intermediatecompressible body 74 interposed betweensupport panel 44 andfront body 40.Compressible bodies Adhesive 46 can bondbodies seal 22. - In other embodiments, shown in
FIGS. 8 and 9 , ahead seal 76 comprises a resilientlycompressible foam core 78 with anintegral skin 80.Skin 80 is denser thancore 78 so thatskin 80 can provideseal 76 with a protective cover as well as serve as asupport panel 82 in the form of flanges that lie generally parallel towall 16.Support panel 82 can be used for mountingseal 76 to wall 16 via aconventional fastener 84 and a metal bar 86 (FIG. 8 ) or via achannel 88 that includes slots for receiving support panel 82 (FIG. 9 ).Bar 86 andchannel 88 may extend fully or partially along the length ofseal 76.Dimensions Seal 76 has the general shape of a parallelogram to makeseal 76 more compliant in response to vertical motion ofvehicle 10. This same shape can be applied to dockseal 20 as well. -
FIGS. 10-13 illustrate a dock seal 94 (e.g., head seal, lateral seal or lower seal) that includes a hollowcompressible body 96 connected to asupport panel 98.Dimensions 100 and 102 (FIG. 13 ) represent the seal's compressible projection and panel projection, respectively.Compressible body 96 comprises a protectivepliable cover 104 that is supported and held taut between twocollapsible frame mechanisms 106. - In this particular example, each
mechanism 106 includes a generally rectangular frame 108 (or some other suitable shape) with a generallyU-shaped brace 110. The actual shapes offrame 108 and brace 110 may vary.Rotatable couplings 112 pivotally connect both legs ofbrace 110 to intermediate points onframe 108. Acentral section 114 ofbrace 110 can pivotally rotate within one ormore anchors 116 that are fixed relative towall 16.Frame 108 includes asection 118 that can both slide and pivot within aslot 120 defined by atrack member 122. The pivotal connections atanchors 116 andcouplings 112, and the combination pivotal/sliding connection atslot 120 allowframe 108 and brace 110 to move between the positions shown inFIGS. 12 and 13 . - To help hold
cover 104 taut, anelastic member 124 held in tension pulls anouter edge 126 of eachframe 106 towards each other. Examples ofelastic member 124 include, but are not limited to, a latex tube, a neoprene cord, helical spring, elastic strap, and the like.Elastic member 124 can be attached to frame 108 in any suitable manner. A similarelastic member 128 can be used for holdingcover 104 to supportpanel 98, while aperipheral lip 130 oncover 104 can provide sealing betweenwall 16 anddock seal 94. - In some cases,
elastic member 124 can be used for urging the dock seal to its expanded position. In other cases, however, whereedge 126 moves in a generally linear motion between its positions ofFIGS. 12 and 13 (i.e., moves in a direction that is substantially perpendicular to wall 16), an additional elastic member ortension spring 132 may be needed to urgedock seal 94 to its expanded position. - Even though various head seals and lateral seal have been shown as generally straight elongate members, it is well within the scope of the disclosure to provide similarly constructed dock seals of other shapes and designs. Instead of one long member, for instance, head seals 22 and 76 can be comprised of two or more shorter segments that are mounted end-to-end to create an elongate seal assembly of a desired length.
- In other cases, as shown in
FIG. 14 , ahead seal 134 includeslateral segments 136 that extend downward toward twolateral seals 138. In this example, the dock seal assembly does not include a bottom seal. Apliable cover 140 extending downward fromsegments 136 and overlappinglateral seals 138 can cover the gap betweenseals upper edge 26 ofvehicle 10 from digging in between the upper end of a lateral seal and the lower adjoining surface of a generally straight head seal. - As an alternative to the embodiment of
FIG. 14 ,FIG. 15 shows a way of providing additional compressibility at anupper end 142 of alateral seal 144. Althoughseal 144 includes asupport panel 146 of standard thickness,panel 146 does not extend to the very top ofseal 144. In this example, ahead seal 148 can be of any design including, but not limited to, the designs ofFIGS. 3 , 7, 8 and 9. - Although the invention is described with respect to various examples, modifications thereto will be apparent to those of ordinary skill in the art. The scope of the invention, therefore, is to be determined by reference to the following claims:
