Definitions

  • the present invention relates to a rotating mechanism for a turnstile, respectively.
  • turnstiles respectively.
  • the simple devices of this type have the disadvantage that they only act in one direction, and that the turning resp. The blocking effect cannot be reversed.
  • the direction of rotation is also to be temporarily blocked, as is customary for access control devices.
  • the lock should only be opened when the object or person to be let through has been identified.
  • This lock is conventionally implemented by means of locking bolts which prevent the turnstiles from rotating.
  • This locking device now has the serious disadvantage that it cannot be opened under load. I.e. that the locking pin cannot be moved out of its locked position because it is wedged by the load pushing against the opening direction. This leads to problems in particular if, for example, security gates are to be unlocked immediately in an emergency, and pressure is already exerted on the locking members by first persons.
  • the object of the present invention was now to find a mechanism which allows a reliable lock of such locking members, the lock being able to be lifted easily even under load.
  • At least one wrap spring freewheel is provided as the blocking element, which acts on the axis of rotation of the blocking element.
  • a wrap spring freewheel has the great advantage that it can also be used under load, i.e. if pressure is exerted on the rotating mechanism against the blocking direction, is releasable. It is also characterized by a very simple structure, which makes it interference-free and inexpensive to produce.
  • a preferred embodiment of the invention is characterized in that the wrap spring freewheel has a helical spring, preferably wound several times around a rotating cylinder, one end of which is attached to a stationary carrier part, and the other end of which rests freely on the rotating cylinder. It is preferably provided that the free end of the spring can be displaced tangentially to the rotary cylinder in two opposite directions by means of an actuating member in such a way that in one end position of the spring end the rotary cylinder can be freely rotated in both directions, and that in the other end position of the spring end the rotary cylinder only is still freely rotatable in one direction and blocked in the other direction.
  • the turnstile can be set up so that it can only be turned in one direction, and the turnstile can also be unlocked and turned in both directions.
  • this device can be coupled, for example, to a fire alarm system that releases such a turnstile in the event of a fire.
  • the rest position of the spring end can be selected such that the turnstile can be turned in both directions, and the one-sided Locking effect can be set up by active switching.
  • a slip clutch effect can be achieved, in which the locking member can be moved against the locking direction with the application of a certain force.
  • This braking effect can be adjusted by positioning the free end of the spring band between the two end positions practically as desired, from freely rotatable to blocked.
  • actuating member can be actuated electromagnetically. This allows the function described above to be switched on or off fully automatically via a corresponding control. Turn off.
  • Another preferred embodiment is characterized in that two oppositely acting wrap spring freewheels are provided. This means that a turnstile can be operated in two directions / blocking directions with little effort.
  • the blocking member is driven by a motor, preferably an electric motor. This enables fully automatic turnstiles to be created.
  • a single locking bar arranged perpendicular to the axis of rotation or two locking bars arranged at an obtuse angle to one another is provided as the locking member. are. In combination with a drive, people can be isolated who do not have any disruptive have against the passage direction moving arms of a turnstile, which is particularly for passages in railway or. Lift access is advantageous.
  • FIG. 1 the schematic view of a turnstile bar is shown.
  • a bracket 1 is rotatably supported in a carrier 2.
  • the ends of the rotary cylinder 3 of the bracket 1 are located in the freewheel bushings 4 and 5, which in turn are connected to the carrier 2.
  • Two electromagnetic switches 6 and 7 are attached to the side of the freewheel bushings 4 and 5, for example. Using these switches 6, 7, the freewheel bushings 4, 5 can be set such that the rotary cylinder 3 can either be freely rotated in both directions, or that the rotation is blocked in one direction.
  • the bracket 1 is now either completely blocked, can only be rotated in one direction or the other, or can be rotated in either direction.
  • FIG. 1 The structure of a wrap spring freewheel according to the invention is shown schematically in FIG.
  • a pin 8 which has the same diameter as the rotary cylinder 3, is fastened to the upper support 2.
  • a helical spring band 9 is wound in the manner shown both around the pin 8 and around the end of the rotary cylinder 3.
  • the upper end (not shown) is connected to the pin 8, for example.
  • the lower end 9 'of the spring band lies freely against the rotating cylinder 3. Due to the spring action, the spring band is pressed against the circumference of the rotary cylinder. If the rotary cylinder 3 is now rotated in the direction of arrow A, the contact pressure and thus the frictional force of the spring 9 on the rotary cylinder 3 increases, and the rotary cylinder 3 can no longer be rotated.
  • the rotating cylinder 3 is rotated in the opposite direction (arrow B)
  • the spring band 9 is easily carried along by the friction, whereupon the contact pressure is reduced, and the rotating cylinder can be rotated on the spring band 9 with only slight friction.
  • a one-way rotary lock is thus easily realized.
  • the end 9 'of the spring band can be pulled tangentially to the rotary cylinder in the direction of arrow B by means of a suitable actuating member, preferably an electromagnetic switch, whereupon the contact pressure of the spring band 9 is applied the rotating cylinder 3 is reduced in such a way that it can also be rotated without problems in this direction (arrow A).
  • the blocking effect can thus be removed with little effort.
  • the particular advantage also lies in the fact that this blocking action can also be canceled if a force acts on the bracket 1 in the blocking direction. This allows fully automated operation such a locking device.
  • the rotary cylinder 3 is preferably driven by a motor.
  • wrap spring freewheels are particularly suitable for the simple and inexpensive retrofitting of existing turnstiles.
  • a preferred embodiment variant of a rotating mechanism is shown in top view in FIG.
  • a double-acting wrap spring freewheel mechanism 10 as was shown, for example, in FIG. 1, is accommodated in a device box.
  • This rotary locking mechanism is arranged, for example, in a through-channel delimited by lateral rods 13 and 14. If, for example, a person now wants to pass this channel in the direction of the arrow, he / she gets between the two blocking bars 12 and 12 'according to FIG.
  • the lock of the wrap spring freewheel mechanism 10 which blocks the movement of the axis of rotation 11 in both directions in the basic position shown, is lifted in the passage direction, for example by an identification device (not shown), the person in the passage direction can pass this lock, the now Barrier bar 12 'blocks the passage for subsequent people, as shown in Fig. 3 b).
  • the axis of rotation 11 can be pivoted back into the basic position shown in FIG. 3 a), while removing the blocking effect in this direction.
