  • Patent number: 9011058
    Abstract: A fastening element includes a holding part with a support plate and expanding cheeks, and a locking part guidingly received in the holding part. The expanding cheeks include cantilevered walls formed adjacent the support plate, which are offset radially outwardly with respect to a guide wall of the support plate which guides the locking part. The locking part can be pushed through the support plate substantially without force until it reaches inwardly protruding ramp projections formed on the expanding cheeks, which provide a better lever ratio for spreading the expanding cheeks.

  • Patent number: 8763208
    Abstract: A device for connecting at least two belts, the belts having transversely oriented connecting bars. The device includes at least one longitudinal wall and at least one edge wall opposite the longitudinal wall and formed on a base plate. Hold-down means are present between each longitudinal wall and each edge wall. At least one of the longitudinal walls and the edge walls has at least one attaching recess in which at least one connecting bar is inserted for securing belts retained by the hold-down means in the area of the base plate against displacing in the longitudinal direction.

  • Publication number: 20120124780
    Abstract: The invention relates to a device for connecting at least two belts (21, 22) having transversely oriented connecting bars (23), wherein at least one longitudinal wall (2) and at least one edge wall (7, 8) opposite the longitudinal wall (2) are formed on a base plate (1). Hold-down means (13, 14, 15, 16) are present between the or each longitudinal wall (2) and the or each edge wall (7, 8). One of the longitudinal walls (2) and/or one of the edge walls (7, 8) has or have at least one attaching recess (17, 18) in which at least one connecting bar (23) is inserted for securing belts (21, 22) retained by the hold-down means (13, 14, 15, 16) in the area of the base plate (1) against displacing in the longitudinal direction.

  • Patent number: 7992940
    Abstract: An actuating device for a fixing rod (7) that is to be displaced in a longitudinal direction and can be rotated to release a latching connection (9, 10) comprises a coupling slide (4) which can be displaced in a bearing sleeve (2) and which, via a coupling arm (5) fitted pivotably to the bearing sleeve (2), drives a coupling head (6) that is connected in a rotationally fixed manner to the fixing rod (7). The fixing rod (7) can thus be rotated by actuating the coupling slide (4).

  • Patent number: 7955038
    Abstract: A turnlock fastener (1) for the connection of two components features a cover plate (4) and a base shaft (5) which is formed on the cover plate (4) and which extends away from the cover plate (4), at which at least two opposing rigid locking stands (10, 11) are positioned at a distance from the cover plate (4) and extend outward from the base shaft (5) in the radial direction. In addition, a fixing arrangement is provided to secure the turnlock fastener (1) to a first component which possesses at least two radial elastic spring limbs (14, 15) which are each arranged between two locking stands (10, 11) and which are connected at one end with the base shaft (5) and which extend away from the base shaft (5) with the other free end in the direction of the cover plate (4). That way, the turnlock fastener (1) can be secured ahead of time within certain relatively large dimensions of insertion openings of different sizes and with relatively large pullout forces.

  • Publication number: 20110020093
    Abstract: In a fastening element (1) comprised of a holding part (2) configured with a support plate (4) and expanding cheeks (5) and of a locking part (3) that is guided displaceably in said holding part (2), formed adjacent the support plate (4) are cantilevered walls (16) that are offset radially outwardly with respect to a guide wall (13), which, in order to guide the locking part (3), bears flush against the shaft portion (6). As a result, the locking part (3) can be pushed along substantially without force until it reaches inwardly protruding ramp projections (14) formed on the expanding cheeks (5), even when said expanding cheeks (5) are flexed inward, and with the advantage of a better lever ratio for spreading the expanding cheeks (5).

  • Patent number: 5217337
    Abstract: A two-part fastening clip made of a hard-elastic plastic material for fastening a piece of molding to a panel. The device includes an upper part having a cover plate, with the molding being secured to one side of the cover plate, a stopper element that extends perpendicularly out from an opposite side of the cover plate in a direction away from the molding and a bulge on its free end that tapers conically in both its axial directions. The device also includes a lower part that can be anchored in a hole in the panel and has a socket casing having a through opening therein for receipt of the stopper element of the upper part and a constricted edge in the opening behind which the bulge of the stopper engages to lock the two parts together.
