Abstract

A mounting member is provided with an alignment ring and a plurality of outwardly projecting posts unitary therewith. Each post has a threaded bore for receiving a mounting screw. The member is temporarily releasably secured within a mold with the distal ends of the posts displaced inwardly from an adjacent interior surface of the mold and with the openings of the bores directed towards the adjacent interior mold surface. An article is rotationally molded to encapsulate the member with at least the distal end portion of each post embedded in a formed wall of the article.

Dependent claims

The method for fabricating an article molded from a molding resin having a wall with a mounting member embedded as an insert wherein, upon completion of the molding step, said mounting member can accommodate the attachment of a device to the wall of the article, said method comprising the steps of:

providing a mounting member having an alignment ring with a plurality of posts unitary with the ring, each post projecting outwardly from said ring and having a distal end defining a threaded bore for receiving a threaded fastener;
positioning said mounting member within the cavity of a mold and temporarily releasably securing said mounting member to said mold with the openings of said bores facing an interior surface of the mold;
molding said article to form a wall of the article in which is embedded at least a portion of each said post with at least said threaded bore of each said post communicating with the exterior of said article, with said alignment ring being spaced from said formed wall, and with said alignment ring being encapsulated with said molding resin along with any portions of said posts extending from said formed wall to said alignment ring;
permitting said resin to at least partially solidify;
and
releasing said mounting member and article from said mold.
