Embodiments of the present invention generally relate to devices configured to plug holes within panels, and, more particularly, to hole plug assemblies having a double-lip design.
Various devices and components include panels and the like having holes formed therein. During an assembly process, the holes may receive and retain fasteners, or allow tubing, wiring, or the like to pass therethrough. In some instances, however, a hole may not be utilized. Similarly, the hole may be reserved for a future application, for example. Hole plugs are used to securely cover and close holes formed within panels of a device.
The hole plug 10 includes a main body 12. The main body 12 includes a central covering base 14 configured to cover a hole. The base 14 is integrally formed with an arcuate, bell-shaped upper lip 16 that extends upwardly from outer edges of the base 14 and circumferentially extends around the base 14.
The hole plug 10 also includes a lower lip 20 that radially extends from the base 14 underneath the upper lip 16. The lower lip 20 also circumferentially extends around the base 14. As shown in
The upper and lower lips 16 and 20, respectively, are flexible and configured to allow the base 14 to be inserted into the hole. During this insertion process, the upper and lower lips 16 and 20, respectively, snap into a securing relationship with respect to the edges 22 of the panel 18.
In particular, as panel thickness is increased, the vestige v (that is, the portion of the upper lip 16 above a top surface of the panel 18′) decreases. The decrease in the vestige v occurs because the upper lip 16 opens wider to accommodate the thicker panel 18′, and therefore tends to flatten. At some point, panel thickness causes the top lip 16 to completely flatten against the panel 18′ such that it is unable to accommodate a thicker panel. An exemplary range of panel thickness that may be accommodated by a typical hole plug, such as the hole plug 10, is on the order of 2 mm.
In order to accommodate thicker panels, therefore, the height of the upper lip 16 may be increased so that the vestige v is increased. However, for various applications, the increased height of the upper lip may prove to be visually and functionally unacceptable. Additionally, it has been found that an increased height of the upper lip may adversely affect the retaining ability of the hole plug.
Certain embodiments of the present invention provide a hole plug assembly that includes a covering base connected to a first lip, at least one extensible member having a first portion connected to one or both of the covering base or the first lip, and a second lip connected to a second portion of the at least one extensible member. The at least one extensible member is configured to expand and contract with respect to a central axis of the covering base.
The first lip and the second lip are configured to securely fasten to an edge of a panel defining a hole within the panel. The at least one extensible member is configured to allow the first and second lips to securely fasten to panels of increased thicknesses.
The at least one extensible member may include a bellows. The at least one extensible member may include a first extensible member connected to one or both of the covering base or the first lip, and a second extensible member connected to the first extensible member. For example, the at least one extensible member may include multiple bellows.
The covering base, the first lip, the at least one extensible member, and the second lip may be integrally formed together. Further, the hole plug assembly may be formed of an elastomeric material.
Before the embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
The upper lip 46 includes an arcuate bulge 52 that connects to a terminal flange 54. The flange 54 and the lower lip 50 are configured to compressively sandwich an edge of a panel therebetween.
An end of the bulge 52 opposite the flange 54 connects to the bellows 48. The bellows 48 includes a flexible ledge 56 that is directed inwardly toward the central axis x of the assembly 40. The ledge 56, in turn, integrally connects to a curved intermediate portion 58 which, in turn, integrally connects to a flap 60 that connects to the base 44 and/or proximate the union of the lower lip 50 and the base 44. The assembly 40 may include additional bellows 48. For example, an upper bellows may integrally connect to a lower bellows that integrally connects to the base 44. The additional bellows allow for increased extension between the upper and lower lips 46 and 50, respectively.
The assembly 40 may be integrally formed from a single piece of resilient material, such as an elastomeric material that allows the assembly 40 to flex. Alternatively, the bellows 48, for example, may be formed of a separate piece of flexible material that is secured to the upper lip 46 and base 44 through bonding or the like.
In operation, the circumferential bellows 48 allows the upper lip 46 to separate from the lower lip 50 over a greater distance, as compared to the conventional hole plug 10, which is shown and described with respect to
As shown, the panel 70 is thin enough that the bellows 48 does not greatly expand. Instead, the ledge 56 remains substantially parallel with the base 44.
Therefore, instead of increasing the height of the bulges 52 in order to accommodate thicker panels, the bellows 48 is able to expand in order to provide an increased and conforming gap between the upper and lower lips 46 and 50, respectively. For these reasons, the upper lip 46 remains visually and functionally acceptable with respect to various different applications.
Thus, embodiments of the present invention provide a hole plug assembly having an extensible portion, such as a bellows, between upper and lower lips that is configured to expand the gap between the lips in order to accommodate varying panel thicknesses. In contrast to conventional hole plugs, the assembly 40 can accommodate a much wider range of panel thicknesses, such as, for example, on the order of 5 mm. In the past, double-lip hole plug designs were unable to accommodate panels having such a thickness. However, the embodiments of the present invention are configured to be used with such panels.
The assembly 40 may be sized and shaped differently to accommodate any kind of panel. For example, while the assembly 40 is generally shown as circular, the assembly 40 may be shaped as a rectangle, square, triangle, etc.
While various spatial and directional terms, such as top, bottom, lower, mid, lateral, horizontal, vertical, front and the like may used to describe embodiments of the present invention, it is understood that such terms are merely used with respect to the orientations shown in the drawings. The orientations may be inverted, rotated, or otherwise changed, such that an upper portion is a lower portion, and vice versa, horizontal becomes vertical, and the like.
Variations and modifications of the foregoing are within the scope of the present invention. It is understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the present invention. The embodiments described herein explain the best modes known for practicing the invention and will enable others skilled in the art to utilize the invention. The claims are to be construed to include alternative embodiments to the extent permitted by the prior art.
Various features of the invention are set forth in the following claims.
