Benefits of technology

[0008]Embodiments of the present invention provide a bushing that is easily positioned within a component. Embodiments of the present invention provide a bushing that is safely and securely anchored with respect to a component. Further, embodiments of the present invention provide a bushing that is less susceptible to damaging the component during an insertion process.
[0010]An outer surface of the leading end may be rounded in order to prevent snagging, scraping or otherwise damaging the component. One or both of the leading and / or trailing ends may be inwardly flanged in order to retain a fastener. A plurality of fastener engaging members, such as lobes, tabs, indentations, or the like, may inwardly extend into the fastener passage proximate the trailing end. The plurality of fastener engaging members may be configured to abut a portion of a shaft of a retainer in order to retain the fastener. The fastener may be configured to pivot about an area where the plurality of fastener engaging members retain the portion of the fastener.

Problems solved by technology

A bolt moving within the bushing 10 may make alignment of the bushing 10 and bolt with respect to components more difficult.

Embodiment Construction

[0034]FIG. 5 illustrates an isometric view of a bushing 30 according to an embodiment of the present invention. The bushing 30 may be formed of hardened thin wall material, which is in contrast to various conventional bushings that are formed from rolled thick wall material or solid stock. Thus, the bushing 30 is lighter than conventional bushings, while exhibiting similar strength.

[0035]The bushing 30 may be configured to be pushed into a molded hole of a component, or injection molded in place. The bushing 30 includes a generally cylindrical main body 32 defining an interior passage 34 that extends from a leading end 36 to a trailing end 38. The bushing 30 is configured to be positioned within an opening, hole, passage or the like a component, such as a plastic cap or the like. A series of stepped ribs 40 and 41 outwardly extend from the main body 32. As shown in FIG. 5, two series of ribs 40 are shown. One series includes horizontally aligned ribs 40, while the other series inclu...

Abstract

A bushing includes a cylindrical main body having a leading end and a trailing end, wherein a fastener passage is defined within the main body, and a plurality of ribs outwardly extending from the main body. The plurality of ribs are configured to securely position the bushing with respect to an opening formed in a component.

Description

RELATED APPLICATIONS[0001]This application relates to and claims priority benefits from U.S. Provisional Patent Application No. 60 / 872,834 entitled “Bushing Assembly,” filed Dec. 5, 2006, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]Embodiments of the present invention generally relate to a bushing assembly, and more particularly to a bushing assembly (which may be formed through drawn metal or other types of fabrication) configured to securely retain a fastener, such as a bolt.BACKGROUND OF THE INVENTION[0003]In various applications, bushings are used when securing components together. For example, a bushing may be used with a bolt to secure a first component, such as a plastic housing cap, to a second component, such as a work-piece to which the housing cap is configured to be secured. Typically, the bushing is positioned within a hole of the first component and a screw or bolt is passed through the bushing to secure the first component to ...
