20110236153 | SCREW WHICH CAN BE SCREWED INTO A COMPONENT - The invention relates to a screw which can be screwed into a component and which will resist further screwing into an internal thread within said component once a maximum torque has been reached. For this purpose, a screw body having an external thread is combined with a screw drive element which projects into a bore within said screw body and, within said bore, is connected to the screw body via static friction. At least part of this combination is made of a plastic material, with the static friction having the effect of a slipping clutch when a maximum torque acts on the screw drive element. The screw drive element is connected to the screw body via a ratchet in such a way that when the screw body is unscrewed from the internal thread within said component, turning said screw drive element will cause the ratchet to engage, thereby entraining the screw body. | 09-29-2011 |

The connecting member is mounted between the assemblies by means of a self-cutting screw penetrating the connecting member and one of the assemblies, which screw is grooving its thread into both parts in such a way that, starting from a stable end position of the one assembly and the connecting member, the screw is adapted to be screwed into the connecting member as well as into the one assembly by means of thread grooves such that, by means of the self-cutting thread of the screw, the connecting member and the one assembly are held in a fixed position with respect to each other, and the other assembly is fastened directly to the connecting member. | 09-30-2010 |
20100186900 | FRICTION WELD ASSEMBLY OF A PLURALITY OF SUPERPOSED PLATES - The invention relates to a friction weld assembly of a plurality of superposed plates, said plates being held together by a connection body which rests on the upper plate by means of a collar and is formed as a slender cone ending in a tip. The connection body comprises a driving element in the region of the collar thereof, for the attachment of a pressure and rotation tool. A girder formed from the slender cone and penetrating from the upper plate into the lower plate, and a girder protruding from the lower plate along the inner surfaces thereof, form a friction welding region extending onto the slender cone. | 07-29-2010 |
20100119772 | METHOD FOR PRODUCING A FRICTION -WELDED CONNECTION AND DESIGN OF THE FRICTION-WELDED CONNECTION - The invention relates to a method for producing a friction-welded connection between a plurality of superimposed flat components held together by a connecting member, wherein a collar of said connecting member rests on an upper component and the front end of said connecting member forms a friction-welding zone with a lower component, said friction-welding zone being produced by rotation and pressure of the connecting member. After formation of the friction-welding zone, the rotation of the connecting member ceases at the end of a first step and, in a second step, upon cessation of the rotation of the connecting member prior to contact of the collar with the upper component, a pressure is exerted on the connecting member by a pressure-applying tool, said pressure pressing the collar against the upper component because of a deformation. | 05-13-2010 |

20090311075 | SELF-TAPPING DRILL SCREW - The invention relates to a self-tapping drill screw that is screwable into a sheet piece and comprises a slotted head for accommodating a tool, a threaded shank, a slightly conically tapering hole-forming part and a hole-grinding part having a conical piece. The hole-grinding part has a radial shoulder that forms a hole and coaxially surrounds the conical piece, engagable with the sheet piece, in a ring-like manner, has a much larger diameter than the conical piece and merges with the hole-forming part via a rounded annular edge. | 12-17-2009 |
20090078094 | Apparatus for aligning fasteners having radially symmetrical polygonal heads in a feed device - The invention relates to an apparatus for aligning fasteners having radially symmetrical polygonal heads in a device for feeding these fasteners to a processing station. A tubular piece having axially running grooves in its interior is provided in a feed channel for the fasteners, the number of these grooves corresponding to the number of edges on the heads of the fasteners, and the diameter of the groove corners on the inlet side of the tubular piece being greater than the width across the corners of the polygonal heads, the grooves tapering from a large width to a narrow width in the transport direction in such a way that fasteners entering the tubular piece are captured with a great clearance in relation to the grooves and leave the tubular piece with narrow clearance and therefore in the aligned position. | 03-26-2009 |
20090010732 | Fixing clip for joining two superimposed flat components - The invention relates to a fixing clip for joining two superimposed flat components each having one penetration in alignment with the other. The fixing clip is characterized by a mounting part with two arms for contact with the upper component and an expanding part attached to the mounting part for spring-loaded engagement of the lower component, wherein the mounting part with the expanding part forms a hole passage in alignment with the penetrations and the mounting part receives a cap screw, wherein said cap screw penetrates the two penetrations and the hole passage with a threaded shank and is adapted with its head between the two arms to engage the arms both in a pre-assembly position and also in a holding position. As the screw is screwed into the hole passage and as the expanding part expands, the screw transitions out of the pre-assembly position into the fixing position, in which the threaded shank holds the expanding part in its expanded position and presses the two components together. | 01-08-2009 |
