Description

(54) RIVET (71) We, "ETABLISSEMENTS DE JOND", a Belgian Body Corporate, Sint Laureisstraat, 48-Antwerpen-Belgium, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to a rivet. More particularly, the invention is concerned with a rivet which can be fitted in a way known per se through one or a plurality of parts or plates to join same together, the rivet being provided with a collar which can enter an opening in the part or plate to prevent the rivet rotating relative to the part or plate.
Such rivets are known, notably from German Patent No. 1,284,168. Rivets of this kind have a cylindrical or prismatic body.
More particularly, a hexagonal portion thereof is to be fitted into an opening of a corresponding shape in such a way that, when a bolt is then screwed into a hollow stem of the rivet, the rivet cannct be driven into rotation. Experience has however shown that the provision of the hexagonal portion causes some drawbacks, in that the rivet can still be driven in rotation relative to the part or plate when said parts or plates are made of very thin sheet due to the engagement surfaces on either side of the hexagonal portion being too small. Due to the hexagonal shape, excessive play cannot be allowed. Consequently, it is out of the question to use such rivets in combination with straight or curved slots.
It is an object of the present invention to obviate the above drawbacks.
According to the present invention, there is provided a rivet comprising a head, a tubular body of circular cross-section which can be deformed to form a shoulder opposed to said head, and a collar of square or rectangular external cross-section interconnecting the body and the head.
Preferably, the head is also of circular cross-section.
The tubular body can be provided with screw-threading on its internal surface to receive a bolt or the like.
The present invention will now be further described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a side view, partly in section, of one embodiment of a rivet according to the present invention, the rivet being shown fastened to a plate; Figure 2 is a cross-section taken along the line II--II in Figure 1; and Figure 3 is a similar view to Figure 2 but showing another embodiment of the invention.
Referring first to Figure 1, the rivet shown therein is designed to fit into an opening 2 in a part or plate 3, and comprises a circular head 1 and a tubular cylindrical body 4 of circular cross-seotion. The body 4 is provided with screw-threading on its internal surface to receive a screw-bolt for fastening a second plate or similar part to the plate 3. In order to secure the rivet to the plate 3, the body 4 can be locally deformed to form a shoulder 5 opposed to the head 1, the shoulder and head engaging opposite sides of the plate 3.
To prevent the rivet from rotating in the opening 2, a collar 6 of square (Figure 2) or rectangular (Figure 3) external crosssectional shape is provided integrally interconnecting the body 4 and the head 1. Edges of the collar 6 engage edges of the opening 2 and thereby prevent the rivet from being rotated. The rivet can be used not only with openings having straight sides as shown, but also in slightly curved slots of open or dosed shape. Rotation of the rivet is impossible in cut-outs of this kind, at least where the rivet size is suitably selected according to the cutout proper.
The height of the collar 6 may of course be larger or smaller than the thickness of the plate or plate with which the rivet co-operates.
WHAT WE CLAIM IS: 1. A rivet comprising a head, a tubular body of circular cross-section which can be deformed to form a shoulder opposed to said

2. A rivet as claimed in Claim 1, wherein the head is also of circular cross-section.
3. A rivet as claimed in Claim 1 or 2, wherein the tubular body is provided with screw-threading on its internal surface.
4. A rivet substantially as hereinbefore described with reference to the accompanying drawing.
