PANEL PLUG
ABSTRACT
A panel plug comprises a planar body, an angled flange, and retaining leg elements. The leg elements comprise four segments in series. A first segment extends away from the body; a second segment extends generally radially outwardly and away from the body to a distance sufficient to snugly engage the aperture in the automotive body when the panel is mounted therein; a third segment extends generally radially inwardly and away from the body at an angle of about 35-45 degrees from a line perpendicular to the body; and a fourth segment extends generally radially inwardly and towards or parallel to the body.

Description
Docket No. 525-077 20739~0 PA~EL PLUG
Field of the Invention:
The present invention relates to a panel plug having retainer legs to retain the plug in an aperture in a workpiece such as a motor vehicle body.
Background of the Invention Closure devices such as bang plugs or snap in plug assemblies are used to close openings in motor vehicle and machinery panels. Circular openings in the sheet metal of a motor ~ehicle may for example be provided to act as drain holes to permit excess coatings and paints to drain from the body when it is dipped in a paint bath, or to permit access to the spaces enclosed by body panels.
A variety of closure devices are known in the art. One class of closure devices are bang plugs, which are installed in the aperture with an impact device that causes a V-shaped cross-bar in the bang plug to extend laterally through slots in the bang plug to hold the bang plug to the panel. The disadvantage of most bang plugs is that the openings for the cross-bar must subsequently be plugged with a sealant, and that they can be difficult to remove if this is necessary. Various snap-in plugs have also been known, but these have generally been unsatisfactory in their ability to seat into and seal against an aperture.

SUMMARY OF THE INVENTION
It is an object of the invention to provide a panel plug which is useful for closing apertures in a motor vehicle body. It is an object of the invention to provide such a plug that requires no crossbar or special impact tools to install, yet which can seat securely in a panel opening, and which can also be readily removed.
A panel plug in accordance with one embodiment of the invention comprises a planar body having a size sufficient to cover an aperture in the automotive body.
Intersecting reinforcing ribs are preferably integrally formed with the body. The planar body has a peripheral flange located around the perimeter of the body which extends radially outwardly from the body and tapers and extends downwardly at an angle of about 20 degrees to about 25 degrees relative to the plane of the planar body. The flange is provided to abut a portion of the automotive body surrounding an aperture in the automotive body. Two folded leg elements are located at opposing edges of the perimeter of the body, each of which is integrally formed with the body. Each leg element comprises four serial segments, namely, a first se gment extending generally downwardly and perpendicularly away from the body, a second segment extending generally radially outwardly and downwardly away from the body to a distance sufficient to snugly engage the aperture in the automotive body when the body is mounted therein, a third segment extending generally radially inwardly and downwardly away from the body at an angle of about 35-45 degrees (preferably at about 40 degrees) from a line perpendicular to the body, and a fourth segment extending generally radially inwardly and 207391~
towards or parallel to the body.
A sealant such as a heat activated foaming sealant is preferably located on the flange, whereby the plug can be sealed to the automotive body.
Other objects, aspects and ~eatures of the present invention in addition to those mentioned above will be pointed out in or will be understood from the following detailed description provided in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF
THE PREFERRED EMLODIMENT
Referring now to ~IGS. 1-6, a panel plug in accordance with one embodiment of the invention is shown generally as 20. Common numbers in the drawings refer to common elements. Plug 20 is adap~ed, as shown in FIG. 5, to engage a workpiece 22 such as an automotive body to close an aperture 24 such as a paint drain hole extending therethrough. The workpiece 22 has an outer surface 25 and an inner surface 26. The aperture 24 is defined by at least one sidewall 28 extending from the outer surface 25 to the inner surface 26.
Plug 20 comprises a planar body 30. Body 30 has a size sufficient to permit body 30 to cover aper~ure 24.
Body 30 has no openings therethrough, and has a downward facing first face 32 for locating against workpiece 22, and an upper second face 34 for facing away from workpiece 22. Intersecting reinforcing ribs 35 are preferably integrally formed with body 30 to give strength.
A peripheral flange 36 is located around the perimeter 38 of body 30. Flange 36 extends radially outwardly from body 30 and is angled downwardly away from the plane of body 30. Flange 36 preferably is angled downwardly relative to the plane of body 30 by an angle A as shown in FIG. 6 which is about 20 degrees to about 25 degrees. Flange 36 is provided to abut a portion of workpiece 22 in a perimeter area 29 of aperture 24. A sealant 40 is preferably located on flange 36 on the side of first face 32 of body 30 so that plug 20 can be sealed to workpiece 22. Preferably sealant 40 comprises a heat activated foaming sealant such as a plastisol and a blowing agent.
Two folded leg elements 42 are located at opposing edges 44 and 46 of the body 30. Each leg element 42 is integrally formed with body 30. Each leg element 42 comprises four segments in series. A first segment 48 extends generally downwardly away from body 30. Preferably first segmen~ 48 extends perpendicularly to body 30. A second segment 50 extends from first `" 5 _ 2073910 segment 48 generally radially outwardly and downwardly away from body 30 to a distance sufficient to snugly engage aperture sidewall 28 when body 30 is mounted into aperture 24. A third segment 52 extends from second segment 50 generally radially inwardly and downwardly away from body 30. Third segment 52 preferably extends from second segment 50 at an angle X of about 35 to about 45 degrees from a line perpendicular to body 30, as shown in FIG. 6. Most preferably, third segment 52 extends from second segment 50 at an angle X of about 40 degrees from a line perpendicular to body 30. It is desirable for the second segment 50 to extend from the first segment 48 to the third segment 52 at an angle such that the second segment 50 is also at an angle of about 35 to about 45 degrees from a line perpendicular to body 30. It is most preferable that this angle be about equal to the angle of angle X. A fourth segment 54 extends from third segment 52 generally radially inwardly and towards or parallel to body 30. Preferably, there is a joining zone 56 between the first and second segments 48 and 50 which is generally a smooth curve rather than a sharply creased joint. Similarly, a joining zone 58 between the second and third segments 50 and 52 is also generally a smooth curve rather than a sharply creased joint. A joining zone 60 between the third and fourth segments 52 and 54 is also generally a smooth curve rather than a sharply creased joint.
Body 30 and leg elements 42 are preferably stamped from sheet steel or aluminum. If desired, galvanized or other treated materials may be used. The stamped leg elements 42 are initially flat elements, and are bent into the desired four segment shape.
The present invention provides a snap-in plug that is useful to close apertures in workpieces such as 207~910 automotive bodies. The invention improves over prior art bang plugs by eliminating the openings needed for the bang plug cross-bars. It improves over prior art snap in plugs by providing retaining leg elements that can be easily snapped in place, that remain snu~ly secured, yet can easily be removed when necessary.
It is an object of the invention to provide a panel plug which is useful for closing apertures in a motor vehicle body. It is an object of the invention to provide such a plug that requires no crossbar or special impact tools to install, yet which can seat securely in a panel opening, and which can also be readily removed.
