Abstract
The present invention is a physical barrier for an orifice in a panel member which includes a plastic carrier and a patch adapted to adhere to the carrier and the panel member. The patch is comprised of a heat-activated material. The patch is joined to a portion of the plastic carrier and encapsulates a peripheral edge of the plastic carrier. Joining the patch and the plastic carrier preferably employs use of traditional vacuum-forming techniques. The plastic carrier is attached to the panel member and the patch is heated to generally flow. The patch cools and forms a seal between the interface of the plastic carrier and the panel member while a portion of the patch is disposed between the plastic carrier and the panel member filling any gap therebetween.
Description
- This application claims priority as a Continuation-In-Part to U.S. patent application Ser. No. 09/992,365 filed on Nov. 19, 2001 and Patent Cooperation Treaty Application No. PCT/US02/36308 filed on Nov. 13, 2002;
- the contents of each are incorporated herein in their entirety.
- This invention relates to devices and methods for sealing orifices in panel members.
- Physical barriers are commonly used to seal orifices in certain objects, such as panel members in motor vehicles, buildings, household appliances, etc. These barriers normally are used to prevent physical materials, fluids, and gases, such as environmental contaminants, fumes, dirt, dust, moisture, water, etc., from passing through the orifice or cavity. For example, an automotive panel, such as a door panel, typically has several small orifices in the sheet metal, which are created for various reasons during manufacturing. Further, various structural components of automobile bodies have a variety of orifices, hollow posts, cavities, passages and openings that can allow contaminants from the engine and the roadway into the passenger compartment. These holes, orifices, and cavities are typically barricaded with duct tape, butyl-based plastic patches, and sealing plugs made from foam, rubber or some other material. Another known physical barrier for cavities involves introducing a foam product into the cavity, and using a fiberglass matting to fill in the cavity.
- One type of known physical barrier is a combination of a metal carrier and a patch of heat flowable material. The metal carrier is inserted into and retained in the orifice to be sealed. Next, the patch is overlaid on the carrier and heated so as to form a seal over the orifice. The metal carrier supports the center of the patch so as to prevent the patch from collapsing into the orifice. This solution is unsatisfactory for a number of reasons. First, the metal carrier is difficult to install into the orifice. Namely, a force multiplying tool and/or a machine is needed to apply a large amount of force to sufficiently flex the retaining means on the metal carrier to allow installation. Second, the metal carrier is heavy while also being relatively expensive to manufacture. The use of other materials for the carrier has previously been limited because patch materials have not been available which adhere to disparate materials. For example, known patches adhere only to metal. Thus, previously both the panel member and the carrier were required to be metal.
- Further, when a carrier is inserted into and retained in the orifice to be sealed, differences in material thicknesses often produce a gap between the carrier and the panel member. With traditional physical barriers, the patch is applied over the carrier and thus any gap between the carrier and the panel member remains. Thus, contaminants present in the gap are trapped. Additionally, the gap may expand or retract under operating conditions and thus produce a seal failure by separating the patch from the panel member.
- Accordingly, there is a need for a physical barrier that produces an effective and robust seal about the orifice of the panel member. Specifically, a physical barrier that overcomes the possible seal failures associated with the gap between the carrier and the panel member is greatly desired.
- The present invention is a physical barrier for an orifice in a panel member which includes a plastic carrier having a peripheral edge. The present invention further includes a patch adapted to adhere to the plastic carrier and the panel member. The patch is attached to a portion of the plastic carrier and encapsulates the peripheral edge of the plastic carrier.
- Additionally, the present invention includes a method of sealing an orifice in a panel member. The method includes the step of joining a patch made of a heat-activated material to a portion of a plastic carrier such that the patch encapsulates a peripheral edge of the plastic carrier. Next, the plastic carrier is attached to the panel member. Finally, the plastic carrier is adhered to the panel member with a portion of the patch disposed between the plastic carrier and the panel member.

- The
physical barrier 10 of the present invention consists of aplastic carrier 12 and asealer patch 14 as shown in FIG. 1.Carrier 12 includes adeck 16 and at least one snap-fit fastener 18. Together,carrier 12 andpatch 14 formphysical barrier 10 for an orifice in a panel member, wheredeck 16 supports the center ofpatch 14, such thatpatch 14 does not collapse into the orifice.Carrier 12 andpatch 14 may be shaped and sized to accommodate any orifice in the panel member. - The at least one snap-
fit fastener 18 in FIG. 1 is a plurality ofprotrusions 20 which are generally perpendicular to the plane ofdeck 16. These protrusions encompass a majority of the perimeter defined by the protrusions.Protrusions 20 include anedge 22 and a holdingsurface 23. - The at least one snap-
fit fastener 18 in FIGS. 2, 3 and 4 is a plurality of S-shapedclips 24. The long axis of S-shapedclips 24 lies in the place of thecarrier deck 16. S-shapedclips 24 include a holdingsurface 25 and may include atail 26. - The at least one snap-
fit fastener 18 in FIG. 5 is acircumferential trough 28 with alip 30 included on a continuous circumferentialouter wall 32 oftrough 28.Outer wall 32 also includes a holdingsurface 33. - Snap-
fit fasteners 18 may be any fastener which causescarrier 12 to snap into position, i.e., into the orifice to be sealed. The snap-fit fasteners illustrated in FIGS. 1-5 are not meant to be limiting, but rather only demonstrative. - As shown in FIGS. 1, 4 and5,
deck 16 may include acircumferential ridge 34 which defines a recess into which a protrusion (not shown) onpatch 14 may be placed. This helps ensure that thepatch 14 is properly place on the carrier. The ridge-protrusion combination also helps to the patch remain in place during insertion of the physical barrier into the orifice. - As shown in FIGS. 3 and 4,
carrier 12 may also includemultiple legs 36, which are positioned between snap-fit clips 24 and are oriented away frompatch 14. - Now referring to FIGS.6-8, another embodiment of the
physical barriers 10 of FIGS. 1-5 is disclosed. Specifically, theplastic carrier 12 includes aperipheral edge 40. In FIGS. 1-5, theedge 22 of FIG. 1, thetail 26 of FIGS. 2-4, and thelip 30 of FIG. 5 each define theperipheral edge 40 of theplastic carrier 12. To generate a more effective seal when received in the orifice of the panel member,patch 14 is attached to at least a portion ofplastic carrier 12 and encapsulates theperipheral edge 40 of theplastic carrier 12. - As shown, the
patch 14 is attached to theplastic carrier 12 and supported by thedeck 16. To encapsulate theperipheral edge 40, a portion of thepatch 14 is wrapped around and under theedge 22,tail 26 orlip 30 and attached to abottom surface 42. Preferably, thepatch 14 is bonded to thebottom surface 42 by a technique such as vacuum-forming (described below). However, any technique that secures thepatch 14 around theedge 22,tail 26, orlip 30 of theplastic carrier 12 to encapsulate theperipheral edge 40 is contemplated by the present invention. Accordingly, when thephysical barrier 10 is received in the orifice, a portion of thepatch 14 is disposed between theplastic carrier 12 and the panel member. Specifically, a portion of thepatch 14 is disposed between thebottom surface 42 of theedge 22,tail 26, orlip 30 and the panel member. -
Patch 14 is made of a thermoplastic material that flows when activated with heat and adheres to both plastic and metal. Any thermoplastic which adheres to both metal and plastic is suitable for use in the present invention. Adherence to both metal and plastic is an attribute that has not been previously produced in thermoplastic materials. - In one useful embodiment,
patch 14 contains an ethylene-vinyl acetate (EVA) copolymer combined with a styrene butadiene rubber (SBR). One useful EVA is the EL-VAX® 400 series from Dupont. A suitable SBR is the 1006 material from Ameripol Synpol Corp of Akron, OH. -
Patch 14 may also include suitable fillers such talc, mica, tall oil rosin and/or other conventional fillers for thermo-plastics. Talc selected for inclusion inpatch 14 may be of highly pure platy talc such as one or more chosen from the 9900 series from Polar Minerals of Wellsville, OH, while utilized mica may be a phlogopite mica such as one or more chosen from the 5000 series, also from Polar Minerals. A suitable tall oil rosin may be selected from the SYLVAROS series from Arizona Chemical Co. of Jacksonville, FL. - In one embodiment, EVA is present in amounts of 10-40 wt %, while SBR is present in amounts of 5-35 wt %. The balance includes 5-22 wt % talc, 10-45 wt % mica and 10-30 wt % tall oil rosin. A particularly useful material for
patch 14 is a composition of 29 wt % EVA, 16 wt % SBR, 12 wt % talc, 26 wt % mica and 17 wt % tall oil rosin. -
Carrier 12 may be made of conventional plastic materials, with the only consideration being the activation temperature forpatch 14. Thus,carrier 12 must be able to maintain its physical rigidity at the activation temperature; i.e.,carrier 12 should not melt at temperatures used in the chosen heat source. When used in vehicles, the carrier should withstand temperatures normally utilized in the paint and coating drying ovens. While metals may be used, plastics are preferred because of the reduced amount of force needed to install a plastic carrier as compared to a metal carrier. One useful plastic material is nylon. -
Physical barrier 10 may be made by conventional methodologies.Carrier 12, separate frompatch 14, can be formed, interalia, by vacuum forming, injection molding or extrusion.Patch 14 may be formed by similar techniques. Once individually formed,carrier 12 andpatch 14 may be attached to each other prior to installation into a cavity. An appropriate adhesive may be used, but heat staking is preferred. Heat staking is a process by which two plastic parts are effectively spot welded together. - Methodologies of making
carrier 12 andpatch 14 parts into one integral piece may also be utilized. Insert molding, which uses two molds, and two shot molding, which uses one mold, are suitable methods ofmaking barrier 10 wherecarrier 12 andpatch 14 are integral. - As introduced above, and specifically with the embodiments of FIGS.6-8,
patch 14 andplastic carrier 12 may be joined by traditional vacuum-forming techniques generally known to one skilled in the art. The thermoplastic material ofpatch 14 is extruded into a sheet and secured in a vacuum-forming apparatus (not shown). Similarly, theplastic carrier 12 is also loaded into the vacuum-forming apparatus. Optionally, theplastic carrier 12 may receive an adhesive prior to being loaded into the vacuum-forming apparatus. The typically heat-activated or pressure-activated adhesive facilitates the effective attachment of thepatch 14 to theplastic carrier 12. Next, heat is applied and the sheet of material ofpatch 14 is molded over a portion of theplastic carrier 12 and around theperipheral edge 40 by vacuum or suction. Pressure is often applied and the joinedplastic carrier 12 andpatch 14 are cooled. The joinedplastic carrier 12 andpatch 14 are then cut from the sheet of material ofpatch 14. In vacuum-forming thepatch 14 to theplastic carrier 12, the amount of heat applied is limited such that thepatch 14 remains generally solid and theplastic carrier 12 maintains its physical rigidity. - The installation of
barrier 10 is now described.Barrier 10 is inserted into the orifice to be sealed. The snap-fit fasteners flex ascarrier 12 is seated in the panel member.Edges 22,tails 26 or lip 30 (peripheral edge 40) ensure thatcarrier 12 is not over inserted into the orifice.Protrusions 20,legs 36 orouter wall 32 ensures thatcarrier 12 is centered and not twisted in the orifice to be sealed. Holding surfaces 23, 25, 33 are the locations on the respective snap-fit fasteners which abut the panel member aftercarrier 12 has been installed. - By centering
carrier 12, the maximum amount of strain all snap-fit fasteners 18 have to endure is significantly reduced. This reduces the strength of snap-fit fasteners that are needed to properly installbarrier 10, which in turn reduces the amount of force needed to installbarrier 10. Thus, force-multiplying tools or machines are not needed to install the barriers of the present invention. - After installation,
patch 14 is activated to produce a contaminant-tight seal.Patch 14 is activated by heating the patch sufficiently to cause it to flow. Upon cooling,patch 14 will adhere tocarrier 12 and the panel member surrounding the orifice. Any source of heat may be used to activatepatch 14. One particularly useful heat source is an oven associated with drying coatings and paints on vehicles. These ovens operate at multiple temperatures depending on the coating or paint being dried, and typically operate between about 175° F. and about 400° F. -
Patch 14 adheres theplastic carrier 12 to the panel member by producing a seal at the interface therebetween. When thepatch 14 encapsulates theperipheral edge 40 of plastic carrier 12 (FIGS. 6-8), a portion of thepatch 14 is disposed between theplastic carrier 12 and the panel member. Specifically, a portion of thepatch 14 is disposed between thebottom surface 42 of theedge 22,tail 26 orlip 30 and the panel member. Often when theplastic carrier 12 of thephysical barrier 10 is received in the orifice of the panel member, variations in material thickness produce a gap between theplastic carrier 12 and the panel member. The portion ofpatch 14 disposed between theplastic carrier 12 and the panel member fills the gap therebetween. Hence, a very robust, effective and complete seal is formed about the orifice of the panel member. - Plastic carriers with snap-fit fasteners are highly advantageous over known metal carriers because no separate tools or machines are necessary to insert the carrier into a cavity. Metal carriers often require a tool to bend retention tabs at the time of installation. Furthermore, the amount of force required to properly seat the carrier in the orifice is significantly less with a plastic carrier compared to a metal carrier. Plastic carriers may be installed by hand. The reduced amount of required installation force means less problematic installations. The use of plastic carriers is permitted through the use of a patch which will adhere to disparate materials, i.e., plastic and metal. Such a patch has not previously been available.
- While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation, and the scope of the appended claims should be construed as broadly as the prior art will permit.
