Embodiment Construction

[0021] Referring to the drawing, the metal fixing rivet 10 includes: an operation pin 11; and a holding body 12 into which the pin 11 is inserted to assemble one or more elements.

[0022] The pin 11 ( Figure 2A and 2B ) comprises a broad head 13 of circular cross-section joined to an elongated vertical rod 14. The annular bottom surface 15 of this head 13 serves as an operating surface for lifting the pin 11 with a tool during disassembly. The rod 14 has a substantially quadrilateral cross-section and is provided with a first notch 16a, 16b and a second notch 17a, 17b along two opposite, parallel planes. are spaced apart and serve to hold the pin 11 in the upper position and lock it in the lower position, respectively. The second notch 17a, 17b is located higher, immediately below the head 13, while the first notch 16a, 16b is further below, between the second notch 17a, 17b and the end. Each of the four ports 16a, 16b, 17a, 17b has the same chamfered (chamfered), V-shap...

Abstract

A detachable metal fixing rivet comprising a retaining body ( 12 ) and a pin ( 11 ) having an elongate shaft equipped with at least a first notch and a second notch spaced longitudinally along the shaft ( 14 ). The retaining body ( 12 ) is made of cut and folded metal sheet, having a first pair of guide tabs ( 24 a) for guiding the shaft ( 14 ), and a second pair of elastic tabs ( 25 a) provided with a series of latching lugs ( 40 ) that ensure positive locking at the end of the insertion travel of the pin ( 11 ) into the body ( 12 ). The first pair of guide tabs ( 24 a) is provided with at least one spring leaf ( 27 a) cooperating either with the first notch ( 16 a) of the shaft ( 14 ), in an "up," premounted position of the pin ( 11 ), or with the second notch, in a "down," locking position.

Description

technical field [0001] The invention relates to a fixing rivet comprising: a holding body provided with latching means; and an operating pin designed to move the locking means to an active, locked position. [0002] Fixing rivets of this type allow rapid assembly of one or more elements, in particular elements in the form of panels or slabs each provided with a hole. Background technique [0003] Documents FR 2852639 and EP 1473449 describe a plastic rivet comprising a central pin that can be pushed in to lock the assembly. Removal is accomplished by pulling or rotating the pin, thus raising it and pulling out the rivet. Removal is difficult if the rivet is installed in a circular hole and the rotational action is applied to the rivet as a whole rather than to the pin. The rivet then rotates on itself, making removal impossible. [0004] If such plastic rivets are installed in high-stress environments, such as fastening a protective cover under a car engine, the presence ...
