Definitions

  • the invention relates to a centrifugal force-independent fall protection according to the preamble of claim 1.
  • a fall arrest device of this type is described in DE-PS 33 00 331, in which the function is not dependent on centrifugal force, but depends on a torsion spring which acts on the fall arrest device and is usually used to balance the door weight, and the blocking by two mutually movable ones in the blocking position Receiving spaces for locking body-forming devices is created, which are moved against each other in the non-blocking position so that the receiving spaces are not able to accommodate locking bodies.
  • the counter-housing continues to act actively on the locking body in the locked position, so that after the anti-fall device responds and unintentional manipulation of the counter-housing, the anti-fall device could be released.
  • the invention has for its object to improve the known fall protection so that the mating housing has only one function in the application, but no longer influences the blocking after the fall protection has responded and that the undesirable running noises of the device are further avoided.
  • the device according to the invention e.g. only in the vertical lower area of the fall protection provided a number of locking bodies that do not circulate with the ratchet wheel, but are housed in the stationary housing.
  • the locking bodies can also be distributed over the entire inner circumference, but are then e.g. held in the recesses by a magnetic tape.
  • the counter housing rotates, lifts the locking body out of its recesses in the stationary housing, so that they then come into contact with the receiving spaces for the locking bodies in the ratchet wheel, can enter them and then block by engaging in these receiving spaces and by abutting corresponding stops in the stationary housing.
  • the locking bodies preferably locking balls
  • the counter housing only performs a lifting function for the locking bodies. If the locking body in the receiving spaces in the ratchet wheel and the stops in the fixed housing come to rest, the counter housing has no effect on the locking body, so that the locking effect of the fall protection can not be canceled when the counter housing is actuated.
  • Fig. 1 denotes a fall protection device which is provided within a stationary housing 2.
  • a torsion spring is shown, which creates a counterforce for the gate to be secured.
  • the receiving space for the counterweight shaft is provided, a ratchet wheel 5 being connected to the counterweight shaft in a rotationally fixed manner.
  • the ratchet wheel 5 is surrounded by a counter housing 6 which is rotatably arranged within the housing 2.
  • the counter housing 6 has support blocks 7, on which the torsion spring 3 engages.
  • the counter housing 6 is subject to the action of two return springs 8 and 9, which are supported on the one hand on the counter housing 6 in a corresponding cutout 20 and on the other hand on a stop 21 provided on the stationary housing 2.
  • the ratchet wheel 5 which has receiving spaces 10 for locking body 11, the receiving spaces 10 distributed over the circumference of the ratchet wheel 5 open radially outwards and their size and shape are adapted to the size and shape of the locking body 11.
  • the locking body 11 are preferably made of balls.
  • Fig. 5 it can be seen that the receiving spaces 10a of a locking wheel 5a can also be made larger than the locking body, so that easier “catching" the locking body 11 is possible in response.
  • the stationary housing 2 surrounds the ratchet wheel 5 in a distance which is smaller than the diameter of each locking body 11.
  • four recesses 12 are machined in the stationary lower housing 2 in the vertical lower region, which are adapted to the shape and size of the locking body 11, and when the locking body in this Recesses are, as shown in Fig. 3, the ratchet wheel 5 can overrun the locking body freely.
  • the recesses 12 are followed by stop tracks 14 which open into stops 15 for the locking body. So that the device is effective in both directions of rotation, the stop tracks 14 extend on both sides of the actual recess 12.
  • the counter housing 6 Arranged below the recesses 12 is the counter housing 6, which has recesses 16, the lowest point of which corresponds to the deepest point of the recess 12, with lifting paths 17 connecting to the recess 16 in the counter housing 6 on both sides, which when the counter housing 6 is rotated cause the locking body to be lifted out of the recesses 12 and thus lead the locking body into the effective area of the receiving spaces 10 of the locking wheel 5.
  • the counter housing 6 is in principle freely rotatably mounted within the stationary housing 2, but is subject on the one hand to the restoring force of the restoring springs 8 and 9 and on the other hand to the force by the spring 3. In addition, its rotational movement is limited by a stop 19 which is located in a groove guide 18 leads.
  • the counter housing 6 is preferably made of a plastic which has the required strength.
  • the fall protection In the working state, the fall protection is in the position shown in Fig. 3, i.e. the force to be monitored, applied by the spring 3, has guided the counter housing 6 into the position shown in FIG. 3 by compressing the spring 9.
  • the lifting paths 17 guide the blocking bodies 5 from the deepest of Recesses 12 in a raised position, in which the locking body 11 must now enter the receiving spaces 10 of the locking wheel 5.
  • the locking body 11 move on the stop tracks 14 and come to rest against the stops 15 of the stationary housing 2 and thereby block the rotational movement of the ratchet wheel 5. This prevents further movement of the gate to be secured, since the ratchet wheel 5 rotatably with the in Drawing, not shown, is connected to the counterweight shaft.
