Abstract: A mounting device for securing plate-shaped elements (5) on a mounting rail (6) includes first (12; 52; 72) and second holding members (17; 57; 77) forming, together a space (16; 42) for receiving a plate-shaped element (5), a fastening member (27; 60) extending through the first (12; 52; 72) and the second (17; 57; 77) holding member and connectable with an anchoring element (23) provided on the mounting rail (6) for securing the mounting device (11; 41; 51; 71) on the mounting rail (6), and at least one resilient element (32; 46; 62; 92) provided between the first holding member (12; 52; 72), which is displaceable relative to the second holding member, and the second holding member (17; 57; 77) for spacing the first and second holding members (12, 17; 52, 57; 72, 77) from each other.

Abstract: A fastening system is disclosed. The fastening system includes a device rail, a holding element mountable on the device rail, and a supporting structure, where the supporting structure defines an opening and includes a gripping surface, and where the opening is an end of an interior space enclosed by the supporting structure. The holding element is insertable into the opening of the supporting structure and, in a back-locking position, the gripping surface grips the holding element.

Abstract: Add-on components (3) are to be fastened to a support part (5) with a simple technical set-up and without a need for tools, with a device (1) for fastening an add-on component (3) to a support part (5), including at least one movable holding element (16) that, when it is inserted into an opening (10) of the support part (5) due to the contact between the at least one holding element (16) and the support part (5), can be moved into an engagement position so as to be inserted into the opening (10), and that, after it has been inserted into the opening (10), can be moved into a catching position by a return movement of the at least one holding element (16) so that the at least one holding element (16) can catch behind at least one edge (9) of the support part (5) in order to create a positive connection between the at least one holding element (16) and the support part (5), and at least one affixer for affixing the add-on component (3) to the device (1).

Abstract: A device (1) for fastening an add-on component (3, 4) to a support part (5), including at least one catching part (8) that can be inserted into an opening (10) of the support part (5) and that can catch behind at least one edge (9) of the support part (5) with at least one movable holding element (16) which, when it is inserted into the opening (10), can be moved into a catching position owing to contact between the at least one catching part (8) and the support part (5), so that it can be inserted into the opening (10), and which can be moved into a catching position by a return movement of the at least one holding element (16) after it has been inserted into the opening (10), so that the at least one holding element (16) can catch behind the at least one edge (9) of the support part (5) so as to create a positive connection between the at least one holding element (16) and the support part (5), at least one affixer (12) for affixing the add-on component (3, 4) to the device (1), should make it possible to f

Abstract: A fastening device (21) for placement on a mounting rail having a back-engagement part (22) for insertion into a mounting opening of the mounting rail and for engaging behind edges of the mounting opening of the mounting rail, having a support plate (42) for coming in contact with the mounting rail on the outside, having a spring element (52) for prestressing the back-engagement part (22) in a circumferential direction with respect to an axis of rotation (27) of the back-engagement part (22), which is perpendicular to a plane (E) spanned by the support plate (42), and having a holding device (31) for holding the back-engagement part (22) in a prestressed position, such that the back-engagement part (22) is transferrable from the insertion position into an engagement position engaging behind the edges of the mounting opening by spring element (52) when the holding device (31) is released.

Abstract: A mounting device for securing plate-shaped elements (5) on a mounting rail (6) includes first (12; 52; 72) and second holding members (17; 57; 77) forming, together a space (16; 42) for receiving a plate-shaped element (5), a fastening member (27; 60) extending through the first (12; 52; 72) and the second (17; 57; 77) holding member and connectable with an anchoring element (23) provided on the mounting rail (6) for securing the mounting device (11; 41; 51; 71) on the mounting rail (6), and at least one resilient element (32; 46; 62; 92) provided between the first holding member (12; 52; 72), which is displaceable relative to the second holding member, and the second holding member (17; 57; 77) for spacing the first and second holding members (12, 17; 52, 57; 72, 77) from each other.

Abstract: A tool holder for drilling and chiselling tools includes a receiving sleeve forming a bore with a conically shaped section for receiving a conically shaped shank on a drilling or chiselling tool. Shoulders extending in the axial direction of the sleeve are formed on the surface of the conically shaped section for interengagement with grooves in the drilling or chiselling tool shank so that the sleeve can rotate the tool. Locking elements in the form of axially elongated pins are mounted in the receiving sleeve so that the pins extend transversely of the sleeve axis and tangentially of the conically shaped bore section. The pins are spring biased toward the bore section and are displaceable generally radially relative to the bore. The pins are arranged to seat within an annular groove in the shank of the tool.
