Bei einem Justierelement (3) mit einem Bolzen (4), der als Gewindebolzen ausgeführt ist, und einem Abstützteil (18) ist am einen Ende ein Angriff (6) für ein Drehwerkzeug ausgebildet. Am anderen Ende des Bolzens (4) ist der Abstützteil (18) montiert. Auch an diesem Ende des Bolzens (4) ist ein Angriff (16) für ein Drehwerkzeug ausgebildet, so daß also an beiden Enden des Bolzens (4) Angriffe (6, 16) für ein Drehwerkzeug vorgesehen sind. Mit dem Angriff (6) erfolgt die Justierung nach dem Einsetzen in einem entsprechenden Rahmen, und mit dem Angriff (16) ergibt sich eine einfache Montagemöglichkeit des Justierelementes.
摘要:
A screw for securing sections on a substructure has a shaft (2) with a boring section (4) and a threaded section (5), as well as a screw head (3). The section (6) of the shaft (2) adjacent to the screw head (3) is conically tapered towards the screw head (3). The screw head (3) has bosses and/or recesses on its bottom side (7). When the screw is used to secure sections on a substructure, the section to be secured is pressed by the conical section (6) in the screwing direction against the fixed substructure (11).

In the proposed door or window hinge plate, the spigot component (1) on which the sleeve (2) is placed is provided with a spigot (5) which is mounted in such a way that its height can be altered. An adjustable element (7) in the form of a cap screw (19) engages in a thread (17) cut inside the spigot (5). Axial movement of the adjustable element (7) is prevented by an elevation (15) which protrudes radially into the bore (14). In addition, elevations (15) engage in a groove (11) in the spigot (5), allowing the spigot (5) to move axially but not to rotate. A tool can be inserted through an aperture (22) at the lower end of the spigot section (1). This tool can engage in an inner recess (21) in the adjustable element (7), thereby facilitating adjustment of the height of the spigot (5).

A large-surface plain washer (1) has an opening (5) for inserting a fastener. Engagement elements (13) that increase the engagement with a plate and/or web to be fastened are provided at the surface of the washer (1) that faces in the fastening direction. In addition, projecting spacers (17) shaped as tongues (26) that become effective when several washers (1) are stacked are provided at the lower side of the washer (1). The free end of these tongues (26) may be supported on the top side of the plain washer located directly underneath, so that the washers may be stacked without causing the engagement elements (13) of different washers (1) to engage each other. Individual washers (1) may thus be easily separated from a stack of washers (1), either by rotating or by moving the lowermost washer.

摘要:
In a device for setting a self-drilling clamping fastener (10), a sleeve-like reception part (1), a guiding sleeve (3) and a driving sleeve (4) are held in a housing (5) to which a bit stop (41) is joined. Clamping jaws (2) which hold a traction mandrel (9) of the clamping fastener (10) are arranged in the reception part (1). The guiding sleeve (3) and the driving sleeve (4) can be coupled to each other in one direction of rotation by means of a wrap spring coupling (34). In order to carry out the traction movement, the guiding sleeve (3) is locked with respect to the housing (5), so that the threaded bolt (17) is drawn into the driving sleeve (4) provided with an inner thread when the driving sleeve (4) makes one more turn. In order to restore the device to its initial position, the direction of rotation of the rotary drive (25) is reversed.
摘要:
A screw (3) is used to join two profiled elements (1, 2). The screw has a drilling part (4), a thread part (5), an unthreaded shank section (15) and a screw head (7). The sum (S) of the length (B) of the drilling part (4) and the length (G) of the thread part (5) is equal to or less than the clearance (W) between two webs (10, 11), following one after the other in the drilling/screw-in direction, of the profiled elements (1, 2) to be joined together. Thus, the process of drilling into web (11) does not begin until the thread part (5) has already exited web (10).
摘要:
A large area washer with a perforation (2) through which a fastener passes has a peripheral border (4) which forms the peripheral limit (3) and which is constructed from one or more longitudinal steps or curves. Individual sections (6) of the peripheral border (4) are set back in the longitudinal direction of the latter from the sections (5) in a plane parallel to, and at a distance from, said sections. The transitions (7) between the mutually offset sections (5, 6) of the peripheral border (4) are curved or sharp-angled.This type of washer can be made of relatively thin-walled material but is nevertheless suitable for use in unmatching devices.
摘要:
Ce dispositif (1), qui sert à l'insertion et à la pose de rivets d'avance aveugles autoforeurs (2), comporte des mâchoires de serrage (3) qui retiennent la broche (16) d'un rivet aveugle. Ces mâchoires (3) se déplacent dans un guide (4) dont les rainures sont ouvertes radialement vers son axe médian (6). Le fond des rainures (8) et le bord correspondant (9) des mâchoires de serrage (3) font un angle aigu identique par rapport à l'axe médian (6) du guide (4). Le guide (4) peut se mouvoir axialement dans un boîtier résistant à la torsion. Une languette (12) associée aux mâchoires de serrage (3) glisse dans une fente longitudinale (13) du boîtier (5). A l'avant du boîtier (5), un capot de fermeture (10) présente une ouverture (24) pour l'introduction de la broche (16) d'un rivet aveugle tirant (2). Ce rivet (2) est retenu par les mâchoires de serrage (3) aussi bien pour l'entraînement en rotation lors du forage que pour la traction consécutive pour la pose du rivet aveugle tirant.
摘要:
Eine Verbindungsvorrichtung zur gegenseitigen Fixierung eines Riegels (4) und eines Pfostens (3) von Kunststoff-Fenstern, welche aus Kunststoffhohlprofilteilen (5, 6) mit eingeschobenem Metallprofilteil (7 bzw. 8) gebildet sind, besteht aus einem Verbindungselement, das einen Bolzen (1) und eine Spannschraube (2) aufweist und mit einer quer zu seiner Längsachse ausgerichteten Gewindebohrung (9) versehen ist, in die die Spannschraube von außen durch den Riegel (4) einschraubbar ist, aus einer durch das Metallprofilteil (7) durchgehenden Querbohrung, die den Bolzen spielfrei aufnimmt, und aus einer Befestigungseinrichtung (17) zur gegenseitigen Kraftübertragung zwischen Kunststoffhohlprofilteil (5) und Metallprofilteil (7) des Pfostens (3). Die Kraftübertragung erfolgt vom Riegel (4) und der Spannschraube (2) aus über den Bolzen (1), das Metallprofilteil (7) und die vorzugsweise als Schraube(n) ausgebildete Befestigungseinrichtung (17) auf das Kunststoffhohlprofilteil (5) des Pfostens (3), so daß jede derartige Verbindung zwischen Riegel (4) und Pfosten (3) mit einer individuell und unabhängig von einer an demselben Pfosten angreifenden weiteren Verbindungsvorrichtung wählbaren Spannkraft erfolgen kann.
