The radial extent of the gasket is less then the radial extent of the first mating flange.
Description
60680-1164 (4635 VIC) Patent Application GASKET ATTACHMENT CLIP
FIELD OF THE INVENTION
The present invention relates to a gasket attachment clip. More particularly, the present invention relates to a ring gasket including at least one integral clip secured to the outer perimeter of a primary sealing element of the gasket to locate the gasket on a mating flange.
to BACKGROUND OF THE INVENTION
Gaskets are often used as seal between mating metal surfaces. One common application involves the placement of a gasket between a head and an exhaust manifold of an internal combustion engine. Another application involves gasket placement between the exhaust manifold and an exhaust pipe flange. Gaskets for either application can be considered high temperature gaskets and more particularly exhaust manifold gaskets since they provide an exhaust seal which prevents the byproducts of combustion exiting the engine from escaping into the engine compartment of a vehicle.
Exhaust manifold gaskets are typically installed during assembly by placing the gasket between an exhaust manifold and its mating component and aligning bolt holes or apertures formed in the gasket with corresponding holes formed in the manifold and mating component. Typically, a threaded fastener passes through the manifold and gasket and engages a corresponding threaded aperture formed in the mating component. Some maneuvering of the manifold and gasket relative to the mating component may be required to align the holes therein with the corresponding threaded apertures of the mating component before the fasteners can be inserted. But during the assembly process, the gasket may slip from its desired position or drop off 60680-1164 (4635 VIC) Patent Application the end of the inserted fastener before it can be fixed in place between the exhaust manifold and its mating component.
Another approach for retaining a gasket against a mating component includes using separate clips to attach the gasket to a particular mating component of an engine part. Using such an approach, a gasket is placed adjacent the mating component, and a clip is attached to the mating component such that the gasket is secured in place between the clip and the mating component. Known clips typically include one end for contacting the gasket about an outer perimeter thereof while a second end is attached to an outer perimeter of a mating component, or even to a connecting portion between mating components. Because such clips are designed to interact with an outer perimeter of a gasket, the gasket itself must cover the full radial extent of a mating surface. Use of such removable clips does not fully eliminate the problems involved in the assembly process whereby a gasket may slip from its desired position.
Separate clips may become dislodged during sub-assembly handling and shipping of mating components, allowing the gasket to slip or drop.
SUMMARY OF THE INVENTION
In accordance with the present invention, a gasket assembly is provided including at least one clip integrally attached to the outer perimeter of a primary sealing element of a gasket for attaching the gasket to a mating flange.
Slipping of the gasket relative to the mating flange is thereby prevented.
The gasket of the present invention includes at least one integral fastening clip 60680-1164 (4635 VIC) Patent Application having a first end, a second end, and an elongated body defined there-between.
The first end of the clip includes a formed end which directly engages and is secured to the outer perimeter of a primary sealing element of the gasket, typically by a low current welding operation. The elongated body of the clip projects downwardly toward a mating flange and terminates at the second end, which includes an integral locking tab angularly extending outwardly therefrom. The locking tab engages a slot feature formed in the mating flange. The slot feature is offset from a sealing perimeter of the mating flange so that the clip does not interfere with the gasket function by interfering with dynamic events during the operating life of the gasket. Thus, the radial extent of the gasket is less then the radial extent of the mating flange. In one embodiment, the elongated body of the clip extends at an acute angle from the plane of the primary sealing element to allow for stacking of multiple parts for shipping. In a further embodiment, the elongated body of the clip is sufficiently long to extend entirely through the slot feature, such that the locking tab extends out past the slot feature to a non-mating side of the first mating flange, thereby creating retention of the gasket against the first mating flange. In this embodiment, manual radial compression of the locking tab is necessary for gasket removal.
The integral clip of the present invention therefore allows a gasket to be properly aligned with and secured to a mating flange prior to assembly. The clip is 2o left in place after assembly, providing visual verification of gasket installation upon completion of a vehicle. At the same time, the radial extent of the gasket need not correspond to the full extent of the first mating flange.
The combination of integral clips with specifically located slot features also simplifies gasket installation, and allows the gasket to be optimally located very easily on a mating component.

60680-1164 (4635 VIC) Patent Application DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
As illustrated in FIGS. 1 and 2, wherein like numbers represent like features, the present invention is directed to a gasket assembly 20 having a primary sealing element 22 installed adjacent a mating flange 24. In FIGS. 1 and 2, mating flange 24 is represented as a flange of an exhaust down-pipe. Primary sealing element 22 is represented as a spiral wound ring gasket in the figures, but it should be understood that other gasket forms may be substituted for the ring gasket. Gasket assembly 20 further includes at least one clip 26 projecting projecting downwardly toward flange 24. Clip 26 includes a first end 28, a second end 30, and an elongated body 32 defined therebetween. Preferably, the first end 28 of clip 26 includes a formed end which directly engages and is secured to outer perimeter 40 of primary sealing element 22, typically by a low-current welding operation. Elongated body 32 of clip 26 terminates at second end 30. Second end 30 includes an integral locking tab angularly extending outwardly therefrom. As seen in the figures, when gasket assembly 20 is mounted against mating flange 24, integral locking tab 34 engages a slot feature 36 formed in mating flange 24. It is important to note that slot feature 36 is offset from a sealing perimeter 38 of mating flange 24 so that clip 26 does not interfere with the function of primary sealing element 22 by interfering with dynamic events during the operating life of gasket assembly 20. As shown in FIG. 2, the radial extent of gasket assembly 20, defined by outer perimeter 40 of primary sealing element 22, is less than the radial extent of mating flange 24. Further, sealing perimeter 38 is defined by the outer perimeter of a recessed portion 42 of mating flange 24. Sealing perimeter 38 therefore closely corresponds with outer perimeter 40 of gasket assembly 20.
60680-1164 (4635 VIC) Patent Application A first embodiment of the present invention is shown with reference to FIG. 3.
In this embodiment, the elongated body 32 of clip 26 extends at an acute angle A
from the plane of primary sealing element 22 to allow for stacking of multiple parts for shipping. Preferably, angle A is about 80°, and more preferably is about 83°. As noted above, clip second end 30 includes an integral locking tab 34 extending outwardly therefrom. When gasket assembly 20 is placed adjacent mating flange 24, locking tab 34 engages slot feature 36 formed in mating flange 24. Again, slot feature 36 is offset from sealing perimeter 38 of mating flange 24 so as not to interfere with the function of the gasket. In this embodiment, because locking tab 34 engages slot to feature 36, gasket assembly 20 is frictionally secured against mating flange 24. Slot feature 36 may also be formed with a ledge 37 placed to receive locking tab 34. As gasket 22 is installed, locking tab 34 is compressed within slot feature 36.
When locking tab 34 is inserted sufficiently to clear ledge 37, locking tab 34 springs audibly outward to frictionally engage ledge 37. In this way, locking tab 34 is positively restrained within slot feature 36, so that a tool must be used to compress locking tab 34 in order to remove gasket 22 from mating flange 24.
In a further embodiment, shown with reference to FIG. 4, clip 26 includes a slightly longer elongated body 32 such that elongated body 32 of clip 26 extends entirely through slot feature 36 allowing locking tab 34 to engage a non-mating side 44 of mating flange 24. In this way, the gasket is retained tightly against mating flange 24. In this embodiment, manual radial compression of locking tab 34 is necessary for gasket removal.
A further embodiment of the present invention is shown with reference to FIG.
As illustrated in FIGS. 1 and 2, wherein like numbers represent like features, the present invention is directed to a gasket assembly 20 having a primary sealing element 22 installed adjacent a mating flange 24. In FIGS. 1 and 2, mating flange 24 is represented as a flange of an exhaust down-pipe. Primary sealing element 22 is represented as a spiral wound ring gasket in the figures, but it should be understood that other gasket forms may be substituted for the ring gasket. Gasket assembly 20 further includes at least one clip 26 projecting projecting downwardly toward flange 24. Clip 26 includes a first end 28, a second end 30, and an elongated body 32 defined therebetween. Preferably, the first end 28 of clip 26 includes a formed end which directly engages and is secured to outer perimeter 40 of primary sealing element 22, typically by a low-current welding operation. Elongated body 32 of clip 26 terminates at second end 30. Second end 30 includes an integral locking tab angularly extending outwardly therefrom. As seen in the figures, when gasket assembly 20 is mounted against mating flange 24, integral locking tab 34 engages a slot feature 36 formed in mating flange 24. It is important to note that slot feature 36 is offset from a sealing perimeter 38 of mating flange 24 so that clip 26 does not interfere with the function of primary sealing element 22 by interfering with dynamic events during the operating life of gasket assembly 20. As shown in FIG. 2, the radial extent of gasket assembly 20, defined by outer perimeter 40 of primary sealing element 22, is less than the radial extent of mating flange 24. Further, sealing perimeter 38 is defined by the outer perimeter of a recessed portion 42 of mating flange 24. Sealing perimeter 38 therefore closely corresponds with outer perimeter 40 of gasket assembly 20.
60680-1164 (4635 VIC) Patent Application A first embodiment of the present invention is shown with reference to FIG. 3.
In this embodiment, the elongated body 32 of clip 26 extends at an acute angle A
from the plane of primary sealing element 22 to allow for stacking of multiple parts for shipping. Preferably, angle A is about 80°, and more preferably is about 83°. As noted above, clip second end 30 includes an integral locking tab 34 extending outwardly therefrom. When gasket assembly 20 is placed adjacent mating flange 24, locking tab 34 engages slot feature 36 formed in mating flange 24. Again, slot feature 36 is offset from sealing perimeter 38 of mating flange 24 so as not to interfere with the function of the gasket. In this embodiment, because locking tab 34 engages slot to feature 36, gasket assembly 20 is frictionally secured against mating flange 24. Slot feature 36 may also be formed with a ledge 37 placed to receive locking tab 34. As gasket 22 is installed, locking tab 34 is compressed within slot feature 36.
When locking tab 34 is inserted sufficiently to clear ledge 37, locking tab 34 springs audibly outward to frictionally engage ledge 37. In this way, locking tab 34 is positively restrained within slot feature 36, so that a tool must be used to compress locking tab 34 in order to remove gasket 22 from mating flange 24.
In a further embodiment, shown with reference to FIG. 4, clip 26 includes a slightly longer elongated body 32 such that elongated body 32 of clip 26 extends entirely through slot feature 36 allowing locking tab 34 to engage a non-mating side 44 of mating flange 24. In this way, the gasket is retained tightly against mating flange 24. In this embodiment, manual radial compression of locking tab 34 is necessary for gasket removal.
A further embodiment of the present invention is shown with reference to FIG.
5. Clip 50 includes a first end 52 attached to the outer perimeter of primary sealing element 22. Elongated body 54 extends radially away from outer perimeter 40 of 60680-1164 (4635 VIC) Patent Application primary sealing element 22 and includes a 90° bend 56 in a direction towards mating flange 24. Elongated body 54 terminates in second end 58 that includes a formed locking tab 60. Locking tab 60 is formed by bending a portion of second end 58 to form a resilient open diamond shape. It should be noted that locking tab 60 need not be formed into a resilient open diamond shape clip, but any suitable geometric configuration may suffice. As seen in FIG. 5, clip 50 is forced through slot feature 36 of mating flange 24, compressing open diamond shape locking tab 60. When fully inserted through slot feature 36, locking tab 60 uncompresses such that two sides 62, 64 of locking tab 60 resiliently engage the perimeter 66 of slot feature 36 on non-1o mating side 68 of mating flange 24. Thus, compression of locking tab 60 is necessary to remove gasket 22 from mating flange 24.
FIG. 6 shows a further embodiment of the present invention. As in FIG. 5, gasket 22 includes a clip 70 having a first end 72 integral with the outer perimeter 40 of gasket 22. Clip 70 includes an elongated body 74 having a 90° bend 76 in a direction toward mating flange 24. Elongated body 74 terminates in second end 78.
As shown in FIG. 7, second end 78 is initially formed with a slot 80 stamped into it such that two parallel sides 82 and 84 are formed in second end 78 with a gap between them. Parallel sides 82 and 84 are bent in opposite directions to form locking tab 88 having a generally diamond shaped profile. Locking tab 88 provides excellent 2o resiliency and is also able to frictionally secure gasket 22 against mating flange 24.
Upon installation from an unlocked position, locking tab 88 compresses as it passes through slot feature 36. When inserted through slot feature 36, locking tab 88 uncompresses audibly so that sides 82 and 84 engage the perimeter 90 of slot feature 36 on non-mating side 92 of mating flange 24. Manual compression of diamond shape locking tab 88 is necessary to remove gasket 22 from mating flange 24.
60680-1164 (4635 VIC) Patent Application According to the present invention, a gasket assembly including a clip is provided that prevents the gasket assembly from becoming dislodged from a mating flange during handling and shipping of mating components. The gasket clip of the present invention also allows a gasket to be used on a mating flange which is less than the full radial extent of the mating flange because the clip itself is secured to the outer perimeter of a primary sealing element of the gasket. The clip engages a slot feature that is offset from a sealing perimeter of the mating flange such that the clip does not interfere with the function of the gasket during the operating life of the gasket. Thus, while the gasket is not permanently secured to the flange, it is secured such that it will l0 not move or slip during shipping and handling of the part. Once assembled, the combined clip and slot feature provides both audible and visual verification of gasket installation, and also ensures easy proper alignment of the gasket on the mating flange.
The disclosed embodiments and examples are given to illustrate the present invention. Various modifications may be employed without departing from the scope of the invention. Accordingly, the following claims should be studied to learn the true scope of the present invention.
FIG. 6 shows a further embodiment of the present invention. As in FIG. 5, gasket 22 includes a clip 70 having a first end 72 integral with the outer perimeter 40 of gasket 22. Clip 70 includes an elongated body 74 having a 90° bend 76 in a direction toward mating flange 24. Elongated body 74 terminates in second end 78.
As shown in FIG. 7, second end 78 is initially formed with a slot 80 stamped into it such that two parallel sides 82 and 84 are formed in second end 78 with a gap between them. Parallel sides 82 and 84 are bent in opposite directions to form locking tab 88 having a generally diamond shaped profile. Locking tab 88 provides excellent 2o resiliency and is also able to frictionally secure gasket 22 against mating flange 24.
Upon installation from an unlocked position, locking tab 88 compresses as it passes through slot feature 36. When inserted through slot feature 36, locking tab 88 uncompresses audibly so that sides 82 and 84 engage the perimeter 90 of slot feature 36 on non-mating side 92 of mating flange 24. Manual compression of diamond shape locking tab 88 is necessary to remove gasket 22 from mating flange 24.
60680-1164 (4635 VIC) Patent Application According to the present invention, a gasket assembly including a clip is provided that prevents the gasket assembly from becoming dislodged from a mating flange during handling and shipping of mating components. The gasket clip of the present invention also allows a gasket to be used on a mating flange which is less than the full radial extent of the mating flange because the clip itself is secured to the outer perimeter of a primary sealing element of the gasket. The clip engages a slot feature that is offset from a sealing perimeter of the mating flange such that the clip does not interfere with the function of the gasket during the operating life of the gasket. Thus, while the gasket is not permanently secured to the flange, it is secured such that it will l0 not move or slip during shipping and handling of the part.
