Definitions

  • the invention relates to a monitoring device for a suspension cable of a door leaf which can be moved overhead and is guided by rollers in running rails.
  • Monitoring devices of this type are known from the prior art, in which a support cable is guided around a roller in the lower door leaf area.
  • the suspension cable is attached to the inside of the door leaf, the suspension cable being guided around a pivotable pawl which is held under spring force. If the suspension cable becomes slack, as occurs, for example, in the event of a cable break or a spring break in a torsion spring holding the winding shaft for the suspension cable, the pawl is pivoted by the relaxing spring in the direction of the running rail, where the pawl either touches the running rail or another the track attached element comes into engagement. Accordingly, these are purely mechanical safety devices that are part of a generic monitoring device.
  • electrical safety devices for monitoring devices are known from the prior art, which cause the drive motor to be electrically switched off when the suspension cable becomes slack, for example when the counterbalance spring breaks, when the cable breaks, when the spring breaks in the area of the transmission of the drive motor and the like.
  • a generic monitoring device an electrical safety device that is switched into the suspension cable and connected to a drive motor for the movement of the door leaf, which can be switched off by the electrical safety device for slack rope, and a mechanical safety device that a on the door leaf Arranged catch member, which catches the door leaf with slack rope with a fixed element relative to the door leaf, the electrical safety device and the mechanical safety device are connected in series such that the electrical and then the mechanical safety device responds.
  • a monitoring device designed according to the invention for a suspension cable of a door leaf that can be moved overhead and is guided by rollers in running rails thus provides a compulsory sequence, such that the electrical safety device responds first and switches off the drive motor, which, due to self-locking of the motor output gearbox, causes the door leaf to move into the closed position can intercept, so that in case of doubt it is unnecessary to trigger the mechanical safety gear. If, for example, a spring breaks and the suspension cable becomes slack for a short time, the electrical safety device responds and switches off the motor, which then tensions the suspension cable again when the engine is at a standstill due to the door leaf moving downwards, so that the mechanical Safety gear is not triggered.
  • the mechanical safety device is then triggered after the electrical safety device, which has slack rope monitoring.
  • the electrical safety device and the mechanical safety device are connected in series in the supporting cable.
  • the mechanical catching device switched on in the course of the supporting cable preferably works with a spring-loaded pawl such that the spring actuating the pawl is pretensioned. If the suspension cable becomes slack, the pawl will be under yours? assigned spring force pivoted and thereby releases a catch member rotatable about an axis, which in turn is pivoted in the catch direction under the force of a spring, in particular an angle spring.
  • a sharp-edged steel cutting edge is preferably arranged on the rotating catch element, which strikes an outer curvature of the running rail and is pressed into the running rail plate by the weight of the door leaf moving into the closed position.
  • the intervention takes place in this respect in a form-fitting manner, the steel cutting edge, which is directed obliquely downward with its cutting edge, being pressed against the running track plate under the force of the spring of the catching element.
  • the series connection of the electrical safety device on the one hand and the mechanical safety device on the other hand is therefore of particular importance, with the constraint that first the electrical safety device and then the mechanical safety device starts.
  • This constraint sequence is preferably achieved by a slack rope securing element which is part of the electrical catching device, the slack rope securing element measuring the suspension rope tension and when the slackening Carrier rope initially holds the suspension rope taut so that the reduced suspension rope tension is not transmitted to the downstream mechanical safety gear over a certain period of time. If the required suspension cable tension is not re-established within this predetermined period of time, the reduced suspension cable tension is transmitted to the downstream mechanical catching device so that it is triggered and the door leaf is intercepted.
  • the supporting cable is preferably guided over a roller at the lower edge region of the door leaf and a deflection roller for the supporting cable is arranged between the electrical catching device and the mechanical catching device.
  • the drive motor should first be switched off, so that depending on the damage, the door leaf is held by the drive motor being at a standstill. Only if this does not preclude further movement of the door leaf in the direction of the closed position does the mechanical catching device come into effect.
  • the mechanical catching device is then designed in such a way that it cannot be swiveled out of its catching position by restarting the drive motor. Rather, it is necessary for this that the mechanical catching device can only be brought back to the waiting position, ie out of engagement with the running rail, in particular by hand, after all errors that have occurred have been eliminated.
  • the catch element is designed as a catch eccentric, that is to say is eccentrically rotatably mounted with respect to a disk circumference, and provided on the fixed object, preferably the running rail, with at least one projection projecting approximately radially to the axis of rotation, preferably pointed tooth-like, which is pivoted under spring force into contact with the object and moves under the weight of the door leaf moving into the closed position presses a surface of the stationary object, preferably an outer curvature of the running rail.
  • the components of this other embodiment are at least largely functionally identical to those of the example described above.
  • this other exemplary embodiment is provided with a blocking member assigned to the eccentric catching member, the shape of which preferably corresponds approximately to that of the catching member in a mirror image.
  • the at least one projection arranged in a comparable manner on the blocking member is used when the catch condition is triggered and thus attacking the fixed object, in particular running track, in such a way that the door leaf in the catching position cannot be moved in the direction of the open position by unauthorized or unwanted attack; in the event of a fall, this blocking member is therefore a deferral device for the door leaf.
  • the function described here is fundamentally possible with only a straight protrusion if the attack on the stationary object takes place far before reaching the dead center as part of the respective rotary movement of the two eccentrics.
  • the catch member and the blocking member are each provided with projections which are inclined with respect to the catch member from the radial to the closed position and with respect to the blocking member into the open position of the door leaf, as can be seen from FIG. 5 of the exemplary embodiment.
  • the catch eccentric and the blocking eccentric move into the rotational engagement position, which is particularly preferably done synchronously in that the movement of one eccentric is derived from that of the other eccentric.
  • one of the eccentrics, in particular the catch eccentric, which is under spring preload is moved into its engagement position by the triggering member, due to a gear connection between the two eccentrics this rotational movement is transmitted in opposite directions to the other eccentric.
  • the catch member and the blocking member are preferably arranged on approximately parallel axes and are each provided with toothings which are formed approximately peripherally over a partial circumferential region in the opposite direction to the respective pointed tooth-like projections and which mesh with one another in a geared manner.
  • a door leaf 1 is shown schematically in FIG. 1, which in the closed position has a roller 2 in its lower side edge region, each of which is guided in a running rail 3, which run in the vertical direction.
  • the rollers 2 are connected to the door leaf 1 via stub axle 4.
  • the rails 3 are fastened to frame parts 5, which in turn are arranged within a building opening on masonry, not shown in the figures.
  • a carrier 6 is arranged on the inside of the door leaf 1 and has a mechanical catching device 7, which will be described in detail below.
  • the carrier 6 is plate-shaped and has on its narrow sides kinked side webs 8 which run essentially parallel to one another and are arranged essentially at right angles to the inner surface of the door leaf 1.
  • the mechanical catching device 7 has a pawl 9 which is fastened to a side web 8 of the carrier 6 so that it can pivot about a bolt connection 10.
  • the pawl 9 is connected at its one end facing away from the carrier 6 via a fastening element 11 to a supporting cable 12 which is fastened with its end facing away from the fastening element 11 to a shaft (not shown) which is pretensioned by means of a torsion spring.
  • the supporting cable runs from the fastening element 11 via a deflection roller 13 and a deflection 14, which is preferably designed as a roller and is arranged between the roller 2 and the side edge of the door leaf 1 facing this roller 2.
  • the support cable 12 thus runs at least with a partial area approximately parallel to the frame part 5.
  • the deflection roller 13 is slidably attached to the door leaf 1 parallel to the deflection 14 having the side edge of the door leaf 1, so that for example by means of the deflection roller 13 a predetermined tension in the supporting rope 12 can be set, or maintained when the rope first slackens the rope tension by means of a electrical safety device (15) is scanned.
  • this electrical catching device 15 is switched into the support cable 12, which is connected via a cable 16 to a drive motor, not shown.
  • the pawl 9 has a bore 17 aligned parallel to the surface normal of the door leaf 1, into which a spring 18 is inserted, which is supported at one end on the carrier 6, the spring 18 being shown in FIG tensioned suspension cable 12 is biased.
  • the essentially L-shaped pawl 9 is rotatably mounted about a pivot point represented by the bolt connection 10, the pawl 9 being supported at its end opposite the fastening element 11 on a pivotable catch member 19 which is pivotable about a pivot axis 20, the Pivot axis 20 runs parallel to the pivot axis formed by the bolt connection 10.
  • the catch member 19 has a shoulder 21 which interacts with the pawl 9.
  • a cutting edge 22 made of steel is fastened, which is oriented in the direction of the running rail 3 and, when the carrying cable 12 is slack, by the weight of the door leaf 1 moving into the closed position into the running rail 3 digs in, so that the cutting edge 22 produces a positive connection with the running rail 3 when the mechanical catching device 7 is activated, which prevents the door leaf 1 from falling further.
  • the catch element 19 is connected to a spring (preferably leg spring), which is not shown in any more detail and which rotates the catch element 19 about the pivot axis 20. if the pawl 9 disengages from the paragraph 21.
  • a spring preferably leg spring
  • the electrical safety device 15 has a slack rope securing element, not shown, which measures the tension of the suspension cable 12 and initially keeps the suspension rope 12 taut when the suspension cable 12 becomes slack, so that the reduced suspension cable tension does not affect the downstream mechanical safety device 7 for a certain period of time is transmitted. Accordingly, only the electrical safety device 15 is activated when the suspension cable 12 is slack for a short time, whereas the mechanical safety device 7 remains in the non-activated state.
  • This mode of operation is given when, for example, one of two springs breaks, which keep the winding shaft under tension, so that the suspension cable 12 only slackens briefly.
  • the door leaf 1 must be intercepted by means of the mechanical catching device 7 in order to prevent the door leaf 1 from falling.
  • the mechanical safety device 7 is triggered after the electrical safety device 15, ie the pawl 9 is pivoted about the bolt connection 10 by means of the spring 18, so that it disengages from the shoulder 21 of the safety element 19.
  • a preloaded spring (not shown) rotates the catch element 19 about the pivot axis 20, as a result of which the cutting edge 22 of the catch element 19 pivots in the direction of the running rail 3 and digs into it in a form-fitting manner.
  • an angle spring is preferably provided.
  • the sharp-edged cutting edge 22 preferably engages on the outer curvature of the running rail 3, the engagement taking place as far as possible with respect to a running roller 2, so that sufficient counter pressure is exerted on the running rail 3, which prevents the running rail 3 from evading to prevent the cutting edge 2 from snapping into place.
  • the series connection of the electrical safety device 15 in front of the mechanical safety device 7 is essential, so that there is a forced sequence of the two safety devices 7 and 15, which triggers the electrical safety device 15 and then the mechanical safety device 17.
  • the mechanical catching device 7 is also designed such that after it has been triggered, the door leaf 1 cannot be restarted or moved from the catching position by the drive motor (not shown). Rather, the mechanical catching device 7 must be brought back into its waiting position, ie out of engagement with the running rail 3, in a very targeted manner after the elimination of all errors that have occurred. This transfer is usually done by hand, so that it is ensured that it is impossible to start the drive motor before eliminating all sources of error. It can also be provided that a signal is triggered by the mechanical safety device 7, which makes it impossible to restart the drive motor after the mechanical safety device 7 has been triggered.
  • the triggering element of the catching device is designed here as a slide 9 ', which has a columnar central part 9' 'and the dimensions of which are laterally projecting web plates 9' '' and is mounted on the carrier 6 'so that it can be moved in a straight line in the direction of movement of the door leaf.
  • the cable 12 ' passes through a sleeve 28 which is supported on the carrier 6' and which engages at the other end on the upper web plate 9 '' 'and which is encompassed by a helical compression spring 18'.
  • the end of the cable adjoining the sleeve penetration is fixed in a fastening element 11 'which, with an external thread section from the lower end of the middle part 9' 'beyond the lower web plate 9' '', emerges from the slider 9 'and by means of lockable nuts 29 when the cable is taut in the position shown in Figure 6 is adjusted.
  • the lower web plate 9 ′′ ′′ of the slide 9 ′ holds the catch member 19 ′ in the position shown in FIG. 6 via a stop 21 ′.
  • the catch member 19 ' comprises a stop part 19''which is connected via an axis 25 with a rectangular cross section to a catch eccentric 19''' to form a torsion-proof unit, as can be seen in particular in FIGS. 5 and 6.
  • the catch eccentric is provided with pointed teeth-like projections in a circumferential area which is pivoted towards the running rail 3 'in the catching position, here three 23 23' 23 '' which, in the order of their pivoting position on the running rail 3, are designed to protrude increasingly radially and seen from the engagement position, not shown, are inclined in the direction of the closed position of the door leaf, so that there is a barbing effect for the movement into the closed position.
  • a blocking member 24 is assigned to the catching member 19 'and has a blocking eccentric 24' which is rotatably mounted by means of an axis 26.
  • the blocking eccentric 24 ' corresponds to the catch eccentric 19' '' in a mirror-image arrangement, as can be seen in particular in FIG.
  • the two eccentrics are connected by gearing 30 and 31, which are formed in each of the eccentrics in the direction of rotation over a partial circumferential area in front of the projections 23 ... and 27 .... Due to the interlocking toothings 30, 31, the rotational movement carried out by the catch eccentric when the catch member is released under a pretensioned spring - counterclockwise in FIG. 5 - to the blocking eccentric 24 '- clockwise in FIG. 5 - so that both projections 23 ... and 27 ... engage the running rail 3 '. Due to the inclination of the running rail 3 'with respect to the vertical, the axis 26 of the blocking member 24 is offset from the axis 25 by a distance designated in FIG. 5 x
  • the mechanical safety device 7' is triggered by the fact that the slide 9 'moves downwards under the force of the prestressed spring 18' - FIG. 6 - so that the stop between the lower one Web plate 9 ′′ ′′ and stop part 19 ′′ comes out of engagement, as a result of which the catch element 19 ′ is pivoted into engagement with the running rail under the force of the prestressed spring, in particular leg spring, which is not shown.
  • This pivoting movement is transmitted via the toothing of the eccentric to the blocking member 24, so that this also comes into engagement with the running rail.
  • FIGS. 4 to 7 show, structural modifications for the second exemplary embodiment have been made in relation to the first exemplary embodiment, such as the design of the carrier 6 ′ adapted to the other catching device 7 ′, the design of the deflection device 14 ′ on the lower edge for the cable 12 'and the formation of the upper deflection for the rope in the form of a skid 13'.
  • the electrical catching device 15 ' is preferably correct with that of the first embodiment.
