Plug

a technology of plugs and apes, which is applied in the direction of pliers, containers, building components, etc., can solve the problems of undesirable sound transmission through the aperture of the panel, undesirable cooling or heating of the passenger compartment, and undesirable material transmission through the apes, so as to facilitate the deformation of the flap parts

AI Technical Summary

Benefits of technology

"The invention provides a plug for impeding transmission of sound and material through an aperture in a panel. The plug has a central portion and a peripheral portion that are separated from each other along one or more cuts. The central portion includes a middle part and one or more flap parts extending from the middle part. The flap parts are positioned to grip the edge of the aperture when deformed and released in the aperture, so that the middle part is positioned in the aperture. The plug can be easily mounted on the panel and is designed to maintain its position over the aperture. The technical effect of the invention is to provide a simple and effective solution for impeding transmission of sound and material through an aperture in a panel."

Problems solved by technology

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.
In addition, the transmission of material through the apes is undesirable.
Also, air flow through the apertures is undesirable, as this may lead to undesirable cooling or warming of the passenger compartment.
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.
However, these plugs require expensive tooling to manufacture, and the cost of each plug is relatively high.

Embodiment Construction

)

[0029] Reference is first made to 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 in FIGS. 2-5, 5A, and 6, the plug 20 is for covering an aperture 22 in a panel 24 to impede the transmission of sound and material through the aperture 22. The aperture 22 is defined by one or more edges 25 (FIGS. 5 and 6). The plug 20 preferably has two or more flap parts 38, 40 included in a substantially elastic central portion 42 and a substantially elastic peripheral portion 44. In the preferred embodiment, the peripheral portion 44 is attached to the central portion 42 by bridge portions 45, and the peripheral portion 44 and the central portion 42 are also separated from each other along cuts 46, 48. As can be seen in FIG. 1, the cuts 46, 48 define the flap parts 38, 40. Also, the central portion 42 preferably includes a middle part 49 from which the flap parts 38, 40 extend. The flap ...

Abstract

A plug for impeding transmission through an aperture defined by an edge in a panel. 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

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 540,063, filed Jan. 30, 2004.FIELD OF THE INVENTION [0002] This invention is related to a plug for impeding transmission of sound and material through an aperture. BACKGROUND OF THE INVENTION [0003] 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. [0004] Sound Is transmittable through the apertures, however, and depending on the structure and its use, the transmission of sound thr...
