The plug is substantially elastic, and has a central portion and a peripheral portion attached to the central portion by one or more bridge portions. The central portion and the peripheral portion are separated from each other along two or more cuts. Also, the central portion includes a middle part and two or more flap parts extending from the middle part, the flap parts being defined by the cuts. The flap parts are positioned to grip the edge after the flap parts have been deformed and released in the aperture.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/540,063, filed Jan. 30, 2004.
- This invention is related to a plug for impeding transmission of sound and material through an aperture.
- Panels, such as a panel inside an automobile door, are included in a structure to strengthen its or for other purposes, such as enclosing an open volume. Such panels are usually made of sheet metal or any other suitable material, and typically include one ox more apertures. The apertures may be included in the panel to provide access, to enable pass-through, for reducing the panel's weight, or for other reasons. Typically, apertures in a panel in an automobile door vary from approximately one inch or less in diameter up to eight to ten inches in diameter, or greater.
- Sound Is transmittable through the apertures, however, and depending on the structure and its use, the transmission of sound through an aperture in a panel may be undesirable. For example, “road noise” may be transmitted through the apertures in the panel inside an automobile door, to a passenger compartment adjacent to the door. In addition, the transmission of material through the apes is undesirable. For example, dust may move through the apertures from the exterior of the automobile, ultimately moving into the passenger compartment. Also, air flow through the apertures is undesirable, as this may lead to undesirable cooling or warming of the passenger compartment. (For the purposes hereof, “transmission of sound and material” shall be understood to include air flow through the aperture.)
- Different approaches to reducing the transmission of road noise and material through panel apertures are known. For example, mastic patches are typically made of plastic or any suitable material, and formed to be slightly larger than the aperture to be covered. Mastic or any other suitable adhesive is placed on one side of the mastic patch. The adhesive side of the mastic patch is placed over the aperture in question, and is held in place by the adhesive. One disadvantage with mastic patches is that, if the patch is not properly aligned on the aperture, the patch may only partially cover the aperture, thereby significantly reducing its effectiveness. Also, it is sometimes necessary to remove a patch (i.e., to permit maintenance or repair), and mastic patches can be difficult to remove. Yet another disadvantage is that a mastic patch typically cannot be reused after it is removed.
- Another approach in the prior art is to provide plugs formed to fit in the aperture, and which are held in place by a series of retention tabs which cooperate with the edges of the aperture. This type of plug is more likely to be installed properly than the mastic patch. Also, such plugs can be designed for relatively easy removal and reuse. However, these plugs require expensive tooling to manufacture, and the cost of each plug is relatively high.
- There is therefore a need for an improved plug for impeding transmission of sound and material through an aperture in a panel.
- In one of its aspects, the invention provides a plug for impeding transmission of sound and material through an aperture in a panel. The aperture is defined by one or more edges. The plug has a central portion comprising a substantially elastic material and a peripheral portion attached to the central portion by one or more bridge portions comprising a substantially elastic material. The central portion and the peripheral portion are separated from each other along two or more cuts. The central portion includes a middle part and two or more flap parts extending from the middle part, and the flap parts are defined by the cuts. The flap parts are positioned to grip the edge (or edges) after the flap parts have been deformed and released in the aperture, so that the middle part is located in the aperture by the flap parts.
- In another aspect, each of the flap parts includes an outer segment located distal to the middle part The outer segments are spaced apart from the peripheral portion by a preselected distance respectively to facilitate deformation of the flap parts.
- In yet another aspect, the flap parts are disposed substantially opposite to each other so that, upon the flap parts having been deformed and released in The aperture to engage the edge respectively, the flap parts hold the middle part substantially over the aperture.
- In another of its aspects, the peripheral portion is adapted to engage a first side of the panel. Also, the flap parts are positioned for engaging a second side of the panel (the second side being positioned opposite to the first side) at the edge of the aperture respectively. The panel is received between the peripheral portion and the flap parts upon releasing the deformed flap parts in the aperture, thereby causing the panel to be gripped between We peripheral portion and the flap parts. The middle part is positioned over the aperture by the flap par.
- In yet another of its aspects, the flap parts are biased to a rest position in which the flap parts are substantially coplanar with the middle part and the peripheral portion. The flap parts are positioned for engagement with the edge (or edges) of the aperture so that, upon deformation of the flap parts and release of the flap parts in the aperture, the flap parts urge the peripheral portion against the first side of the panel.
- In another aspect, the invention includes a panel assembly having a panel with an aperture defined by one or more edges. The panel has a first side and an opposed second side. The panel assembly also includes a plug having a central portion and a peripheral portion. The central portion includes two or more flap parts and a middle part connecting the flap parts, which are made of a substantially elastic material. The peripheral portion substantially surrounds the central portion, and the peripheral portion and the central portion are connected to each other. Also, the flap parts are spaced apart a predetermined distance for engaging the aperture's edge. The plug is mountable on the panel upon deformation of the flap parts, insertion of the flap parts through the aperture, and release of the deformed flap parts. Each of the flap parts is sufficiently elastic that, acting through the middle part, each of the flap parts urges the peripheral portion against the first side of the panel when the flap parts are engaged with the second side, thereby maintaining the middle part over the aperture.
- In yet another of its aspects, the invention includes a method of forming a plug for impeding transmission through an aperture in a panel. The method includes the steps of, first, selecting a substantially planar blank of a substantially elastic material. The blank has predetermined dimensions so that the blank is sufficiently large to cover the aperture and a predetermined area of the panel substantially surrounding the aperture. Second, two or more cuts are to be formed in the blank according to a predetermined pattern to define the flap pans. The flap pans and a middle part therebetween form a central portion of the plug. Also formed is a peripheral portion substantially surrounding the central portion and connected to the central portion at the middle part.
- In another aspect, the invention includes a method of forming a plug for impeding transmission through an aperture in a panel. The method comprises the steps of, first, selecting a substantially planar blank of a substantially elastic material. The blank should preferably be sufficiently large to cover the aperture and a predetermined area of the panel substantially surrounding the aperture. Next, two or more cuts are formed in the blank to define two or more flap parts. The flap parts are included in a central portion and extend from a middle part of the central portion. Also formed is a removal portion of the blank extending from an outer segment of each flap part. Each outer segment is positioned distal to the middle part. Finally, the removal portion is removed so that each outer segment of the flap parts is spaced apart from the peripheral portion by a predetermined distance, to facilitate deformation of the flap parts.
- In yet another of its aspects, the invention provides a plug for impeding transmission through an aperture in a panel. The aperture is defined by one or more edges. The plug has a central portion comprising a substantially elastic material and a peripheral portion attached to the central portion by one or more bridge portions also comprising a substantially elastic material. The central portion and the peripheral portion are separated from each other along one or more cuts. In addition, the central portion includes a middle part and one or more flap parts extending from the middle part. The flap part is defined by the cut. The flap part is positioned to grip the edge at the flap part is deformed and released in the aperture, so that the middle part is positioned in the aperture by the flap part.

FIGS. 1, 1A , 2-5, 5A, and 6 to describe a preferred embodiment of a plug indicated generally by the numeral 20 in accordance with the invention. As can be seen inFIGS. 2-5 , 5A, and 6, theplug 20 is for covering anaperture 22 in apanel 24 to impede the transmission of sound and material through theaperture 22. Theaperture 22 is defined by one or more edges 25 (FIGS. 5 and 6 ). Theplug 20 preferably has two ormore flap parts central portion 42 and a substantially elasticperipheral portion 44. In the preferred embodiment, theperipheral portion 44 is attached to thecentral portion 42 bybridge portions 45, and theperipheral portion 44 and thecentral portion 42 are also separated from each other alongcuts FIG. 1 , thecuts flap parts central portion 42 preferably includes amiddle part 49 from which theflap parts flap parts edge 25 after theflap parts aperture 22, so that themiddle part 49 is located in the aperture by theflap parts - As can be seen in
FIGS. 5, 5A , and 6, theaperture 22 can be defined by one or more edges 25. It will be understood that theaperture 22 shown in the drawings is exemplary, and theaperture 22 can have any shape. Preferably, theflap parts flap parts aperture 22 to engage theedge 25 respectively, the two flap parts hold themiddle part 49 substantially over theaperture 22. As can be seen inFIGS. 5, 5A , and 6, once in position, themiddle part 49 impedes transmission (i.e., of sound and material, including air flow) through theaperture 22. - As can be seen in
FIGS. 2-5 and 5A, thepanel 24 has afog side 32 and an opposedsecond side 34. Theflap parts second side 34 of thepanel 24 at, and/or proximal to, theedge 25. Theedge 25 is at least partially located on thesecond side 34. In the preferred embodiment, theperipheral portion 44, which substantially surrounds thecentral portion 42, is adapted to engage thefirst side 32 of thepanel 34. Also, theflap parts second side 34 at theedge 25 respectively. As shown inFIG. 5A , once theflap parts aperture 22, due to elastic memory of theflap parts 39, 40, theflap parts second side 34, and thepanel 24 is received and gripped between theperipheral portion 44 and theflap parts - As can be seen in
FIG. 1A , theflap parts 38. 40 are biased to a rest position (FIG. 1A ) in which theflap parts middle part 49 and theperipheral portion 44. Upon deformation of theflap parts aperture 22 of theflap parts flap parts peripheral portion 44 against thefirst side 32 of thepanel 24, and themiddle part 49 is held substantially over theaperture 22. - A panel assembly 50 (
FIGS. 2-5 ) consists of thepanel 24 with theplug 20 mounted thereon - Preferably, the
plug 20 is made of any suitable elastic material—i.e., any material that is able to return to its original shape after experiencing strain and removal of deforming stress (sometimes referred to as elasticity memory), such as any flexible or semi-flexible plastic material with as least some acoustic barrier capability, i.e., some ability to impede the transmission of sound therethrough. Any thermoplastics or other plastics (recycled or otherwise) with these characteristics (including “hard” plastics), or rubber or rubber-based materials with these characteristics, would be suitable materials. In the preferred embodiment, theplug 20 is cut out of a sheet of elastic material. The cuts in the material can be made using dies or by any other suitable means. The substantially elastic material preferably has a thickness of between approximately 0.020 inch and 0.120 inch. It will be appreciated by those skilled in the art that theplug 20 can be formed to cover apertures in a variety of shapes, and that the cuts can be made in any suitable pattern. - Although forming the
plug 20 out of an integral sheet of elastic material is the most economic way to create theplug 20, other methods of creating theplug 20 will be apparent to those skilled in the art. For example, if desired, theperipheral portion 44 could be made of a material which is not the same as the material comprising thecentral portion 42. Theperipheral portion 44 is not necessarily made of a substantially elastic material, although it is preferred. Theflap parts bridge portions 45 should be made of a substantially elastic material, however. - It will be understood that, although the preferred embodiment of the
plug 20 includes two ormore flap parts plug 20 including only one flap past could be used, depending on the shape of theaperture 22 and the shape of the flap part. - In use, the
plug 20 can be mounted on thepanel 24 in different ways. For example, theflap parts flap parts aperture 22, and subsequently released. The elastic memory of theplug 20 causer theflap par second side 34 of thepanel 24 near theedge 25 of theaperture 22. Also, the elastic memory of theplug 20 causes theperipheral portion 44 to engage thefirst side 32 of thepanel 24. - Alternatively, the outer edges of the
plug 20 near theflap parts flap parts aperture 22, to engage thesecond side 34 of thepanel 24. - Another approach would be to position the
plug 20 so that thecentral portion 42 is over theaperture 22, and then push on thecentral portion 42. This pushes theflap parts aperture 22, where they engage thesecond side 34 due to elasticity memory of theplug 20. - It is preferred that the
plug 20 is mounted in theaperture 22 manually. However, such mounting can also be effected using aplug insertion tool 60, shown inFIG. 7 . Thetool 60 includes ahandle 62 and a distal or end portion 64 in which twoprongs tool 60 is adapted to mount theplug 20 on thepanel 24, in any and all of the ways described above. - For example, in the preferred embodiment, the
prongs trigger 70 on thetool 60. A user (not shown) places theplug 20 on thetool 60 by inserting theprongs cuts trigger 70 is pressed, theprongs flap parts middle part 49. This causes theflap parts aperture 22, so that thedeformed flap parts second side 34 of thepanel 24. However, at the same time, theperipheral portion 44 remains adjacent to thefirst side 32 of thepanel 24. With the end 64 in theaperture 22, the user releases thetrigger 70, causing theprongs flap parts second side 34 at, or in the vicinity of, theedge 25 of the a 22. - Preferably, the
tool 60 also is adapted to extend theprongs trigger 70 or similar activation means. Thetool 60 is preferably also adapted to retract theextended prongs 66, 68 (not shown), also upon appropriate activation by the user. With theplug 20 on the tool 60 (i.e., theprongs cuts 46, 48), the forward movement, or extension, of theprongs flap parts aperture 22 when theprongs - Preferably, when the
extended prongs aperture 22, theextended prongs flap parts second side 34 of thepanel 24. Theprongs plug 20 mounted on thepanel 24. - Au additional embodiment of the invention is shown in
FIGS. 8 and 9 . InFIGS. 8 and 9 , elements are numbered so as to correspond to like elements shown inFIGS. 1, 1A , 2-5, 5A and 6. - As shown in
FIG. 8 , in analternative embodiment 120 of the plug, each of theflap parts outer segment middle part 149. Theouter segments peripheral portion 144 by a preselected distance (designated as “D” inFIG. 8 ) across agap 176 to facilitate deformation of theflap parts flap part 138 is shown inFIG. 9 . Thegap 176 between theouter segments peripheral portion 144 is beneficial because, where theplug 120 is to be mounted manually, a user (not shown) can more easily grasp theflap parts gaps 176. Theplug 120 could also be mounted using the too) 60. - It will be appreciated by those skilled in the art that the invention can take many forms, and that such forms are within the scope of the invention as claimed. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred version contained herein.
