DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
The present invention concerns a rivet, characterised by the fact that it is made up of two parts, forming two pieces or one single piece, one of them being a hollow rivet comprising a head, a cylindrical stem and possibly a peripherial shoulder on the external side of its cylindrical stem, the other one being a headless hollow cylindrical nail, one end of which is edged and preferably sharp, the other end being hollow with internal dimensions enabling the adjusted threading or passage of the hollow nail through the part forming a hollow rivet up to the shoulder or up the head thereof.
The invention concerns also several alternative of rivets according to the invention as well as methods of implementation of the rivets according to the invention.
2. Prior Art
Several types of rivets are known. The present invention concerns rivets provided for assembling products in band or in sheets, and particularly for assembling joining staples or other joining means for conveyor belts to the ends thereof. To this aim several types of rivets have been used heretofore. There are rivets constituted of one single piece, one end of which has a preformed head; these rivets designed in order to be threaded through holes, previously provided in sheet or band shaped materials which have to be assembled, as well as through joining staples or in any other joining means, the other end which does not comprise a preferred head, projecting from the other side of the materials which have to be assembled in order to be hammered and to form a head on this other side. These well known rivets, used for a long time, have the inconvenience of requiring successively, access to one face of the whole of the materials to be assembled, then access to the other face. This is not practical in many applications and particularly in the case where joining means for conveyor belts have to be assembled to the ends of the conveyor belts.
These operations are most often carried out under actual hard conditions (limited space on the sites in particular in mines). But even under different conditions, for instance in open air or in large industrial workshops, the handling of the ends of large width conveyor belts is rather difficult. It is the reason why solutions have been sought, for carrying out the setting into position of a rivet from one single face of the materials to be assembled, together with its riveting, without having access to the other face of the materials to be assembled. Thus, the U.S. Pat. No. 3,913,180 has disclosed a hollow rivet provided with a provisional anvil threaded into the hollow end of the said hollow rivet. This rivet-anvil is thrusted into holes previously provided in the materials to be assembled. The head of the hollow rivet is then hammered against the anvil, and after crossing the materials is inserted in the holes provided in a support plate, and matching with to the pattern of the holes formed in the materials to be assembled, the circular anvil seating on the support against a flange, the other side of which, generally tapered, is used as an anvil surface. By hammering the rivet head located on the face through which the anvil and the rivet have been thrusted into the holes previously formed, the cylindrical opposite hollow end of the hollow rivet is pushed against the walls slanted towards the upper side of the anvil flange and forms a head which pinches the materials to be assembled in association with the previously formed rivet head, located on the other face of the whole of the materials to be assembled. The anvil is thus released and can be scrapped. This rivet has been largely used, although it presents many drawbacks. In particular, it is absolutely necessary that all the product or material layers to be joined together be provided with holes previously formed.
OBJECT AND SUMMARY OF THE INVENTION
Thus, the present invention proposes a solution to these problems, by providing a rivet, the riveting of which can be carried out in a simple and lab
