Definitions

  • the invention relates to a door drive with catching device according to the preamble of claim 1.
  • the invention relates to drives for door leaves, which basically all door locks are to be understood as the door leaf, the total in the vertical direction between the open position and the closed position have movable TorBank influence, such as overhead moving one-piece overhead doors, gates with roll-up, so-called rolling armor as a door leaf, Deckengliedertore and the same.
  • TorBankdegree such as overhead moving one-piece overhead doors
  • gates with roll-up so-called rolling armor as a door leaf, Deckengliedertore and the same.
  • These gates must be secured, however, that they can move in the event of a failure in their suspension, in particular by breaking the associated weight balancing device, uncontrolled and accelerated to its closed position, because this is especially dangerous for underneath persons and goods.
  • FIG. a sectional door 10 is shown schematically for closing a garage opening 12, wherein for reasons of simplicity, the drive device is not shown here.
  • the garage door drive runs parallel a tether 14 which is wound on a corresponding shaft 16.
  • the tether 14 is guided around a deflection roller 18.
  • a top view of the band 14 and a sectional view through the band 14 are also shown in FIG. From the sectional view it is clear that the band 14 is guided in a C-shaped rail.
  • the shaft 16, on which the tether is wound, is monitored in the manner described above in more detail to the maximum permissible rotational speed.
  • the corresponding catching mechanism can be designed here in a similar manner as in a restraint belt for motor vehicles.
  • this is mounted directly on the rear wall of the garage, so that no deflection roller 18 has to be provided here.
  • a generic door drive which has a communicating with the goal in a guide rail arranged movable guide carriage which is connected via a drive means with the drive means of the door drive in conjunction and is equipped with a catching device consisting of a catch held on the guide catch member.
  • the catch member is movable between a release position and a catch position, wherein it engages positively and non-positively in the catch position on a catch strip.
  • the door leaf In this position of the catch member, the door leaf can move freely. If the weight compensation device of the door leaf fails, the door leaf attempts to reach the closed position under its own weight. Accordingly, it accelerates its movement relative to that of the drive member, wherein a driver part shifts from its gate closed position in the direction of its door opening position relative to the door leaf and thus the guide carriage. As a result, the catch member is transferred from its release position into the catch position, in which the further movement of the door leaf is blocked.
  • Object of the present invention is to develop a door drive with catching device such that the door can be safely intercepted in case of failure of the associated counterbalancing device, the catcher should be designed simple and reliable.
  • the catch member is designed as a two-armed lever which is pivotable about a pivot point.
  • One end of this lever is designed as a pawl, while at the other end a sensing roller is arranged.
  • the sensing roller is guided along a control profile, so that the pawl regularly dives with regular gate movement in successively provided in the catch strip recesses.
  • the follower roller can now follow the control profile and immerse the pawl of the lever in the corresponding recesses of the catch strip or lift it out again.
  • control profile and the catch strip can be integrally formed. They are advantageously designed as a sheet metal profile, with a track of the sheet metal profile forms the control profile and arranged next to this track the catch strip with the corresponding recesses.
  • Catch and control profile can be laterally connected to the guide rail.
  • brackets so a usually C-shaped profile guide rail can be retrofitted with an additional catch strip and with control profile.
  • the catch member may be arranged laterally on the guide carriage by means of a holding device.
  • the catch strip can be arranged with the control profile within the guide rail.
  • the sensing roller is pressed by spring force to the control profile.
  • a corresponding application of the sensing roller to the control profile is possible.
  • a guide carriage 20 of known construction is guided in a guide rail 22.
  • the guide rail 22 is formed by a C-shaped profile.
  • the guide carriage 20 is moved by a serving as a drive means chain 24 via a drive means not shown here along the guide rail back and forth.
  • the guide carriage in here also not shown manner, the door with which the guide carriage is connected by corresponding linkage open or close.
  • a sheet metal profile 26 is arranged, which on the one hand has a catch strip 28 and on the other hand a control profile 30.
  • a plan view and corresponding sectional views of the sheet metal profile in Figure 8 are shown.
  • the catch strip 28 has corresponding recesses 32 and that the control profile 30 is formed wave-shaped.
  • a catch member 34 cooperates, which is designed as a two-armed lever 36.
  • the two-armed lever 36 is pivotable about a pivot point 38.
  • a sensing roller 40 is arranged, while the other end of the two-armed lever 36 is formed as a pawl 42.
  • the sensing roller 40 is arranged laterally offset from the pawl 42, so that it can cooperate with the control profile 30, which is arranged next to the catch strip 28.
  • the sheet metal profile 26 by means of Abkantblechen 44 and 46, which can be screwed together so that they include the guide rail 22, can be retrofitted to the guide rail 22.
  • the catch member 34 forming two-armed lever 36 is screwed by means of a sheet-metal carrier 48 with the carriage 20.
  • the sheet metal carrier 48 is in each case adapted to the length of the guide carriage 20 and connected via its bent ends at the front or rear part of the guide carriage 20 with this.
  • FIGS. 5 and 6 show an alternative embodiment of the catching device.
  • the sheet metal profile 26 is integrated with the control profile 30 and the catch strip 28 within the guide rail 22.
  • the guide rail 22 is slightly higher than that according to the embodiment of Figures 2 to 4.
  • Below the metal profile 26 extends the carriage 20, which is constructed substantially conventional.
  • the guide carriage 20 receives in a corresponding recess 50, the catch member 34 which is formed in this embodiment as a two-armed lever 36 with sensing roller 40 and pawl 42.
  • the sensing roller 40 rolls in the same manner as based on the embodiment of FIGS. 2 to 4 explained along the control profile 30.
  • the direction "door to" is shown by the arrow a. In this direction, therefore, the pawl 42 relative to the pivot point 38 in front of the sensing roller 40th
  • the mechanism of action of the catching device can be explained.
  • the follower roller 40 rests against the control profile 30, wherein the follower roller 40 has just reached a trough of the control profile 30.
  • the two-armed lever 36 is moved about the pivot point 38 such that the pawl 42 is positioned outside of the catch bar 28.
  • the sensing roller 40 is held by the spring 52 in contact with the control profile 30.
  • the sensing roller 40 is shown in contact with a wave crest of the control profile 30.
  • the pawl 42 By corresponding pivoting of the two-armed lever 36 about the pivot point 38 immersed in this position, the pawl 42 in the recess 32 within the catch bar 28 a. Since the control profile 30 extends over the entire length of the guide rail, the pawl 42 thus travels regularly into the successively arranged recesses 32 and is pulled out of these again, depending on whether the follower roller 40 follows a wave crest or trough of the control profile 30.
  • the gate moves due to its own weight at high speed in the direction of the "gate closed" position (arrow a).
  • the follower roller 40 can no longer follow the wave movement of the control profile 30 so that the pawl 42 can no longer be pulled out of the recess 32 in time.
  • the pawl 42 hooks with the front end of the recess 32, whereby the downward movement of the door is stopped.
  • a stop 56 which is arranged in the region of the follower roller 40 on the two-armed lever 36, supported on the bottom of the recess 20 provided in the carriage 20, as shown in Figure 9 c.
  • FIGS. 10 to 15 show an alternative embodiment of the invention. This, in turn, as shown in Figure 10, a guide carriage 20, which is guided in a guide rail 22, as can be seen for example in Figure 14. For reasons of simplicity, it is not shown in the cut-away region of FIG.
  • a holding device 100 is connected to the guide carriage 20, which receives the two-armed lever 36 with its sensing roller 40.

  • the two lateral catching members 34 each cooperate with likewise laterally arranged catching strips 28, as shown in FIG.
  • the catch strip 28 forms in this embodiment simultaneously the control profile on which the feeler roller 40 rolls.
  • the sequence of movements which is traversed during the movement of the guide carriage 20 can be seen in the sequence according to FIG. 11, in which the different positions of the catching member 34 are shown.
  • the catch strip 28 according to the present embodiment is, as is apparent from the figure 14, U-shaped. This means that in each case laterally to the guide rail 22, the sawtooth-shaped profiles of the catch strip 28 are arranged and can interact with the lateral catch members 34.
  • retaining clips 110 as shown in Figure 14, are provided. These retaining clips 114 can be connected in a clamping manner by means of a rotational movement with the guide rail 22 (see FIG. 14a).
