Definitions

  • the present invention relates to a tension lock according to the preamble of claim 1.
  • a window lock is known in which an actuating member which is rotatable with respect to an axis of rotation is provided, on which oppositely moving locking members are pivotally mounted, which are linearly displaced in one component when the actuating member rotates.
  • the working position of the lock is given by driving the locking members moving in opposite directions as far apart as possible.
  • the locking members pivotably mounted on the actuating member, moving in opposite directions bear against a coaxial bolt on the actuating member, namely along obliquely angled surfaces with respect to the stress retrospective on the locking members in this position.
  • the swivel bearings of the locking elements on the actuating element thus remain stressed by the retroactive stress and the closure is in an unstable equilibrium state in the working position, the reaction moments are opening.
  • a window lock is also shown with a rotary actuator, on which locking elements moving in opposite directions are pivoted.
  • the swivel bearings between the locking members and the actuating member are oriented in the direction of the retroactive stress, and absorb them entirely, the closure also being in an unstable state in the working position with regard to the reaction moments.
  • a closure of the type specified in the preamble of claim 1 is also known.
  • the pivoting parts of the locking members are shaped so that, in the working position of the closure, the members abut one another on an inclined plane with respect to the direction of the retroactive stress.
  • the locking members are mutually supported in the working position and in accordance with the angle of inclination of their contact plane with respect to the direction of stress. Because of the inclination of the locking member contact surfaces, however, this closure only partially relieves the pivot bearing in the working position.
  • a turnbuckle of the type specified in the preamble of claim 1, designed as a chain turnbuckle for anti-skid chains, has also become known.
  • support surfaces of the locking members forming the pair lie in the working position, i.e. when the lock is under tension, with regard to the load on the locking members, on an inclined plane, which means that the pivot bearings of the locking members are only partially relieved.
  • the aim of the present invention is to develop a tension lock of the type mentioned in such a way that, in the working position, the pivot bearings between the locking members and the actuating member are relieved of the reaction stress. This is achieved by the features of the characterizing part of claim 1. This completely relieves the pivot bearing.
  • an actuating handle according to claim 6 is furthermore provided on the actuating member, a closure is created which takes up little space, in particular for its actuation, since the actuating handle can practically be pivoted in the plane of the actuating member.
  • a rod-shaped clamping lever 1 is permanently connected to a plate-shaped connecting part 3, on which bushes or bolts of two pivot bearings 5, respectively. 7 are fixed. On these cans resp. Bolts ride corresponding bolts or bushings each of a tie rod 9 or. 11.
  • the anchor ends mounted in this way are hook-shaped and each have support surfaces 13 or vertically oriented with respect to the respective pulling direction S. 15 on.
  • the tension lock shown is mounted free-floating, ie only via the anchor 11 or. 9 and the parts to be braced with it, or the connecting part 3, for example, as shown in dashed lines at 17, can itself be pivoted, centrally stored.
  • one spring element 19 can be operatively connected to the anchors 9 and 11, as shown schematically in the figure, in such a way that this spring element 19 is supported on the one hand on the anchors 9 and 11 and on the other hand on the parts 21 to be clamped with the closure, with which the maximum torque to be overcome can be determined by the characteristic of the compression springs 19.
  • the anchors are mounted to relieve the bearing in such a way that outer hook surfaces 13a, 15a abut one another in the closed position.

Claims (9)

1. Fermeture à genouillère, dans laquelle un mouvement de rotation d'un organe de manoeuvre (3) par rapport à un axe de rotation est transformé en une composante linéaire (S) d'un mouvement de coulissement forcé d'une paire d'organes de verrouillage (9, 11) déplacés dans des sens mutuellement opposés, les organes de verrouillage (9, 11) étant montés pivotants sur l'organe de manoeuvre (3) et portant l'un contre l'autre, en position de travail, par une surface d'appui respective (13,15), caractérisée en ce que, dans la position de travail, les surfaces d'appui (13, 15) viennent s'appliquer l'une contre l'autre perpendiculairement à la direction de la composante linéaire (S) du mouvement de coulissement forcé de telle façon qu'une sollicitation des organes de verrouillage (9, 11) dans la direction de la composante (S) soit absorbée par les surfaces d'appui (13,15).
2. Fermeture à genouillère selon la revendication 1, dans laquelle les organes de verrouillage sont, dans la position de travail, soumis à une force de réaction agissant en traction, dans une direction opposée aux paliers de pivotement (7), caractérisée en ce que les organes de verrouillage (9, 11) sont réalisés sous la forme de crochets et s'engagent l'un derrière l'autre dans la position de travail.
3. Fermeture à genouillère selon la revendication 1 ou 2, caractérisée en ce qu'elle est amenée de la position de repos à la position de travail par dépassement d'un couple maximum de fermeture.
4. Fermeture à genouillère selon la revendication 3, caractérisée en ce que les paliers de pivotement (5, 7) sont disposés, par rapport à l'axe de rotation (17), dans des positions excentrées telles qu'une sollicitation des organes de verrouillage (9, 11) dans la position de travail et dans la direction de la composante du mouvement de coulissement, exerce sur l'organe de manoeuvre (3) un couple maintenant ce dernier dans la position de travail.
5. Fermeture à genouillère selon la revendication 3 ou 4, caractérisée en ce que les paliers de rotation (5, 7) sont disposés dans des positions symétriques par rapport à l'axe (17).
6. Fermeture à genouillère selon l'une des revendications 1 à 5, caractérisée en ce qu'une poignée de manoeuvre (1) fait saillie sur l'organe de manoeuvre (3) au moins dans une direction principalement radiale.
7. Fermeture à genouillère selon l'une des revendications 1 à 6, caractérisée en ce que les organes de verrouillage (9, 11) peuvent être amenés dans la position de travail en s'opposant à la force d'un dispositif à ressort (19).
8. Fermeture à genouillère selon l'une des revendications 1 à 7, caractérisée en ce que l'organe de manoeuvre (3) est monté mobile en rotation sur un axe de rotation à position fixe.
9. Fermeture à genouillère selon l'une des revendications 1 à 8, caractérisée en ce que les organes de verrouillage (9, 11) sont reliés rigidement à des tiges de verrouillage.
