Problems solved by technology

However, it has been found that separate and distinct foam pieces and seals are expensive, bulky and can be difficult to position in the desired position
[0009] Therefore, known methods of plugging components may prove to be time consuming and expensive
Also, to prevent moisture ingress and undesirable sound energy, most, if not all, holes formed through the part are individually plugged with hole plugs, which adds to production time and cost

Embodiment Construction

[0028] Figure 1A A bottom perspective view of a hole plug assembly 10 according to an embodiment of the disclosure is shown. The plug assembly 10 includes a body 12 which may be composed of plastic, rubber, metal or the like. The body 12 may include a peripheral upstanding ring 14 integrally connected to a vertical flange 16 extending radially inward from an upper edge 18 of the ring 14 . A central passage 20 is bounded through the body 12 relative to an inner edge 22 of the flange 16 . As shown, the body 12 is generally configured to have a circular axial cross-section. However, body 12 may be configured in a variety of other shapes and sizes, such as oval, oval, rectangular, triangular, and the like.

[0029] One or more offset protrusions 23 may extend downwardly from the lower edge 25 of the ring 14 . The protrusions 23 may be positioned above the ring 14, below, or offset away from a component such as a panel. Body 12 may include more or fewer protrusions 23 than sho...

Abstract

A hole plug assembly is configured to be secured within a hole of a panel, and may include a main body having at least a portion that is configured to be secured in the hole of the panel, and an expandable layer connected to the main body. The expandable layer is configured to expand into the hole to form a fluid-tight barrier.

Description

[0001] related application [0002] This application is related to, and claims priority from, U.S. Provisional Patent Application No. 61 / 858294, filed July 25, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present disclosure relate generally to devices configured to plug holes in components, and, more particularly, to expandable hole plug assemblies. Background technique [0004] The various devices and components include panels and the like having holes formed therein. During assembly, the holes can receive and hold fasteners, or allow tubes, wires, etc. to pass through them. However, in some cases holes may not be utilized. Similarly, holes may be reserved for future use, for example. Hole plugs are used to securely cover or close holes formed in equipment panels. A typical plug is composed of a resilient material, such as rubber, that allows the plug to flex while providing a liquid-tight barrier. [0005...
