  • Patent number: 10549409
    Abstract: The invention concerns a family of insertable temporary fasteners (100) comprising the following: a body (101) with a bearing face (102) at least one clip (103) with a hooking spur (104) a threaded rod (105, 205) connected to the clip, with a control nut (107, 207) screwed onto the said rod The family comprises at least two temporary fasteners (100) with different diameters and nuts with different lengths (116). The invention also concerns a set comprising such a family of fasteners, along with an installation device (13) comprising a means (26, 30) of detecting the length of the nut. The invention enables the installation device to automatically determine the appropriate tightening torque when installing the fastener based on the length of the nut.

  • Patent number: 8869372
    Abstract: A fastening device for preassembling structural members includes a hollow cylindrical body; a bearing ring provided at a proximal end of the hollow body and against which one of the structural members is intended to bear in a fastening position; a pulling threaded rod extending through the hollow body to be inserted into the structural members; a tightening means connected to the pulling threaded rod for maintaining the structural members against each other, the tightening means including a removable tubular end piece for mounting on a proximal threaded end of the pulling threaded rod that can be locally axially compacted under the action of a force applied on the pulling threaded rod in order to form a radial bead for sandwiching the structural members between the latter and the bearing ring; the fastening device including a sheath.

  • Patent number: 8448929
    Abstract: The invention relates to a riveting tack (50) to be introduced into coaxial openings of at least two elements to be assembled, and comprising a hollow cylindrical body (51), a rod (53) passing through the hollow body and partially provided with an external thread (52a), a nut (54) mounted on the threaded end (53a), two half-clips (56) fixed to the rod (53) and comprising hooking lips (57) on the ends thereof, and a spacer (58) arranged between the two half-clips (56), the rod/half-clip set being axially mobile along the spacer (58) between a first position wherein the hooking lips (57) are radially close, and a second position wherein the two half-clips (56) are retracted inside the hollow body (51) and radially distanced from each other. The invention is characterized in that the set formed by the half-clips (56) and the spacer (58) is, in the cross-section thereof, in the form of a near-perfect circle having a diameter identical to the inner diameter of the openings.
