ABSTRACT:
The present invention relates to a device for mutually fastening at least two portions of a cooking vessel grip, and which is particularly suitable for forming, simply and cheaply, cooking vessel grips defined by two half shells made of thermosetting polymer material (e.g. Bakelite or other phenol-formaldehyde resin) fitted to a central metal core.
BACKGROUND OF THE INVENTION
Cooking vessel grips are known, which comprise a central, metal, typically platelike core, the opposite faces of which are fitted with two half shells made of polymer material, in particular Bakelite or other phenolformaldehyde resin.
The half shells are normally screwed or riveted to each other and/or to the central core, both of which systems obviously involve relatively slow, complex assembly operations, thus increasing overall production cost.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a fastening device designed to eliminate the aforementioned drawbacks of known systems, and which, in particular, is cheap and easy to produce, and ensures effective, long-lasting permanent connection.
According to the present invention, there is provided a device for mutually fastening at least two portions of a cooking vessel grip, the device comprising at least two holes formed respectively through said grip portions and aligned with each other to define a continuous seat for the insertion of a fastening element; said holes having respective axial-stop means cooperating with and on which rest respective end heads of said fastening element to secure said grip portions one against the other; and the device being characterized in that said fastening element comprises a first and a second plug inserted respectively inside a first and a second of said holes, and having said respective end heads; said plugs comprising, at the opposite end to said end heads, respective end portions having irreversible connecting means for securing said end portions of said plugs integrally to each other, after said plugs are inserted inside said respective holes, so that said plugs define a monolithic said fastening element.
More specifically, said end portions of said plugs are inserted concentrically and by a predetermined length one inside the other, and are connected to each other with a predetermined amount of radial interference at at least one contact section : preferably, said end portions of said plugs have been welded to each other at said at least one contact section, e.g. by means of an ultrasonic welding process, after said plugs are inserted inside said respective holes, and after said end portions of said plugs are inserted one inside the other.
The present invention obviously also extends to any cooking vessel grip comprising a device, as described briefly above, for fastening two portions of the grip.
The fastening device according to the present invention is extremely cheap and easy to produce, ensures effective, long-lasting permanent connection, and enables fast, easy, low-cost production of cooking vessel grips, particularly of the type comprising two half shells made of thermosetting material and fitted to a central metal core. It is to be understood, however, that the fastening device according to the invention also applies equally to any other type of grip requiring the connection of at least two grip portions, however shaped and formed.
