  • Some spring monitoring devices must be designed to withstand torques of to withstand over 800 Nm and a spinning of the cable shaft on which this Torques can attack due to the gravity of the gate To block.

  • US Pat. No. 5,697,476 discloses a braking mechanism for braking a garage door Failure of a counterbalance mechanism known with a drum-shaped Braking element on one with respect to the axis of rotation when the door leaf moves rotating torsion shaft radially inward wall with a Toothing detection device is provided, and with a catch member, that from an operating position in which it is detached from the detection device into a Start position is movable, in which it is the detection device for braking the Door leaf detected, and the one radially inside the inward wall arranged, in the course of the movement in the catching position radially outwards in the Detection with the detection device movable catch section has.
  • Pawl trained catch attached to the torsion shaft and radially inward spring-loaded elastically biased and against it away from the detection device directional bias movable by centrifugal force towards the detection device.
  • the Braking element is held by means of a fixed to the outer circumference of the Brake drum designed brake elements guided brake loop can be braked.
  • the object of the invention is to provide a spring monitoring device of the type mentioned in the introduction to further develop that it takes up less space and preferably less material and nevertheless a blocking of high torques occurring in the event of spring breaks allows.
  • the blocking element is thus part of a traction mechanism drum on which another end with the door leaf or the like preferably at its closed position connected lower means is held windable, and preferably integrally formed with the same.
  • the blocking element is therefore not a separate component more, but can be integrated into an existing traction roller.
  • the invention Spring monitoring device is e.g. can also be fully integrated inside the traction roller, i.e. completely enclosed by this.
  • the traction drum or role itself e.g. in the form of a kind of ratchet ring gear as a blocking element or usable. This is a corresponding to the spatial conditions of the rope drum or the same traction drum large ratchet wheel with a large radius created.
  • this Blocking element directed essentially radially inward with respect to the axis Wall on which the detection device is formed and has the catch member a radially arranged inside the inward wall or can be arranged, in the course of the movement into the catching position radially outward into the Detection with the capture device movable catch section.
  • blocking element provided in its interior with the detection device, in which engages the catch member with an outward movement when the spring breaks.
  • the catch element can be much smaller and less material than be trained in the prior art.
  • a low-mass catch member also has the Advantage of lower inertia, so that faster blocking is possible.
  • the blocking device formed from the blocking element and catch member in the inner region of the Blocking element relatively well protected against access or external influences, so that no separate housing needs to be provided for this purpose.
  • the blocking element as a ring section, as Pot-shaped, preferably accessible from the outside hollow housing or as a drum is trained.
  • the catch element is mechanically designed, the Catch section on a radially outward with respect to the axis of rotation, in particular spring-loaded, pre-tensioned pawl for detecting at the radially inward wall to form the detection device protruding ratchet teeth is formed.
  • the catch member is provided with a support surface is in the operating position to support a broken spring the tension sensing and triggering device from the trajectory of the Catch member movable holding element is used and so in relation to the direction of movement of the retaining element is inclined obliquely that the latter at Release after spring break by moving the catching element into the catching position is pushed out of the trajectory.
  • the catch member is around a lever axis offset parallel to the axis of rotation, into which Catch position spring-biased lever element with a first, the Lever arm having catch section and in particular forming the pawl educated.
  • the lever element has a second lever arm, the to interact with the trigger mechanism of the voltage sensing and Tripping device is used, in particular has the support surface is the Available space is more usable and it can be used to trigger the Blocking device usable movements are redirected.
  • the second lever arm serves the purpose of e.g. a spring cone movement in the event of spring break, preferred as described in such a way that a small component of the Pawl preload force on an inclined plane (the support surface) on the Bolt of the cone acts.
  • the trigger mechanism i.e. the Example of the bolt attached to the spring cone or another Holding device or the other holding element not only in his or her Release position but also kicked back or bouncing back becomes. So that such a rebounding trigger mechanism once released cannot reach the second lever arm again, this is preferably such trained that he in the catch position when moving the lever element entirely from the sphere of influence of the trigger mechanism, in particular from the Path of movement of the retaining element, pivots out.
  • lever element is mounted such that the first lever arm in the catch position by the movement of the to be blocked Door leaf or the like is resilient to pressure.
  • Lever arm offers further advantages compared to a ratchet lever loaded under tension in terms of material savings, since a barb element like it on a train loaded ratchet lever would be necessary is avoided. Instead of such a can simply the free end of the lever arm as an engagement area for gripping the pawls be trained.
  • the locking nose with a bevel is provided, which after the pivoting of the lever element Spring break glides over a complementary bevel on the ratchet tooth, whereby the lever element can be guided into the final catch position before a significant torque is transmitted.
  • a locking nose that can Catch section forming free end of the first lever arm itself, or this free end can be, for example, in the form of a bent part have formed locking lug.
  • the configuration with the complementary bevels is particularly important its advantageous that the traction device drums are often made of die-cast a material that is more prone to breakage than sheet metal, for example. It is therefore advantageous if the forces that are really to be absorbed are possible first in the case of a large-scale intervention between the locking nose and the corresponding one Pawl tooth flank can be initiated. That is why the latter moves advantageous embodiment of the invention, the detection device on oblique flank of the tooth, the correspondingly obliquely formed locking nose first radially outwards to the ratchet tooth base, so that you have a large Contact surface between the locking lug and the ratchet tooth flank by means of a corresponding Slip feed achieved.
  • This is particularly advantageous in connection with a pressure resilient lever arm, because with a lever arm resilient to tension, the bevel should be made so inclined on the ratchet tooth flank that in In extreme cases the rupture strength of the ratchet teeth could suffer.
  • the wall does not have to be present throughout, it can be with Breakthroughs may be provided or only in a partial area of the circumference of the blocking element can be provided.
  • the wall does not have to be exactly geometrical sense radially inward. It can e.g. everywhere with Pawl areas should be provided so that they are not a single perpendicular to the radial has directed area piece. It is important that they are essentially or in its entirety is directed inward that the trained Detection device is accessible from the radially inside.
