Definitions

  • the invention relates to a device for locking and unlocking turnstiles with a vertical axis of rotation and directional lock, in which a fixed bridge part arranged above or below the turnstile, a rotatably mounted locking disc on the axis of the turnstile, held in a rotationally secure manner with recesses distributed over its circumference and two locking members held on the bridge part and brought into and out of engagement in the recesses of the locking disk in the axial direction with oppositely acting locking lugs and controllable actuating magnets acting on the locking members are provided.
  • the locking disk is designed in multiple layers, because in addition to the locking members engaging radially in the corresponding recesses of the locking disk, a locking device cooperating with the locking disk is required, which ensures that the turnstile returns to that after each release and rotary movement by 90 ° Position reached in which the locking members engage in the locking disc.
  • gas pressure springs are generally used, which cooperate with correspondingly extensive control curves of the locking disk.
  • the known devices are relatively expensive in terms of their structure and space requirements.
  • the locking members By connecting the locking members to the armatures of the lifting magnets, the locking members can only absorb relatively small forces if the turnstiles should be actuated by force using the known devices.
  • the locking members form relatively long lever arms when the turnstiles are operated by force, which are held at one end by their connection to the armatures of the magnets in the magnet, while relatively large forces act on the other end when the turnstile is operated by force, so that very large moments are exerted on the locking members.
  • a device of the type described at the outset is also known (DE-A-2731 171), in which locking members which run parallel but diametrically with respect to the axis of rotation of the turnstile are provided in the form of elongated locking bolts which are held in guide bushes which are open at the top and bottom are, which in turn extend through the entire height of the cross member. Lifting magnets are held at the end of the guide bushes facing away from the locking disk, the armature of which is connected to one of the locking bolts.
  • the known arrangement leads through the locking members projecting from the locking disk with the surrounding guide sleeves and the lifting magnets provided above the guide sleeves to a large overall height and thus a complex construction.
  • the turnstile When the turnstile is actuated by force, the locking bolts protruding perpendicularly from the locking disk can only absorb small forces without the risk of the guide sleeves being deformed. Since the locking bolts in the guide sleeves only have to be guided with a small amount of play, there is concern with slight deformation of the guide sleeves that the locking bolts jam in the sleeves and the turnstile thus becomes inoperative.
  • the invention is based on the object of developing a device of the type mentioned in the introduction such that, with a reduction in the structural outlay, the turnstile is secured considerably better against violent actuation and a compact design of low height is achieved.
  • the invention provides that the two locking members are each designed as pawls in the form of double-armed pivot levers and that the pivot levers are pivotally mounted on the bridge part about axes of rotation running parallel to the plane of the locking disc.
  • the pawls can be arranged so that they each engage in different recesses of the locking disk offset by 90 ° or 180 °.
  • a particularly advantageous embodiment results, however, if the pawls are offset directly adjacent to one another in parallel and are arranged with mutually facing locking lugs such that they engage in the same recess in the locking disk.
  • the bearing points for the locking members can be arranged in a common support of the bridge part provided above or below the locking disk, which can also serve at the same time for fastening the actuating magnets. This further simplifies the design.
  • lever arms facing away from the locking lugs are not directly connected to the magnets of armatures, but are connected in a geared manner via a lifting linkage to the armatures of electromagnets, which in turn are equipped with a return spring.
  • a mechanical separation of the locking members from the electromagnet is achieved by the aforementioned design, so that the forces acting on the locking members cannot be transmitted to the armature of the electromagnet.
  • the lifting linkage transmits the movements of the armature of the electromagnet to the locking members, only slight rotary movements of the armature being required to transfer the locking members into the different positions.
  • the return spring provided in the electromagnet also acts on the locking members at the same time, so that the springs which are otherwise necessary and which act directly on the locking members are not required for their return after actuation by the magnet and can be accommodated within the magnet in a protected manner.
  • the locking disk is equipped with recesses offset by 45 ° on the circumference for the engagement of the pawls and additionally has recesses offset radially on the circumference by 90 ° for the engagement of a resilient latching device.
  • these recesses can be provided outside the edge region of the locking disc, so that the edge region of the locking disc is available for the additional recesses offset on the circumference for the engagement of the resilient locking device .
  • the arrangement of the recesses cooperating with the locking members, each offset by 45 ° on the circumference of the locking disk, has the advantage that after unlocking the turnstile in one direction or the other and rotating the cross by a little more than 45 °, the unlocked effect is already canceled can and this makes it impossible to turn the locking cross back into the starting position, because the locking bolts engage in the recess of the locking disk which has just been run over when it turns back. In this way it is ensured that a rotary movement of the turnstile is always possible in one direction only, and in each case only by 90 °, and thus the passage of the turnstile is only guaranteed by one person in one direction or the other.
  • the stationary part above or below the turnstile and on the support frame for the turnstile is designed as a cross-sectionally U-shaped profile part.
  • the bridge part 1 carries a locking disk 2, which is held on the axis 3 of the turnstile shown in FIG.
  • the axis 3 of the turnstile is rotatably held in a flange bearing 4 provided on the bridge part 1.
  • a cross-sectionally U-shaped profile part 5 with fastening flanges 5a is fastened on the bridge part 1 by means of retaining screws, in which the most important parts for locking and unlocking the turnstile are accommodated.
  • 5 bearing blocks 6 and 7 are provided in the U-shaped profile part 6 for axes of rotation 6a and 7a running parallel to the plane of the locking disk (FIG. 3), which serve to mount pawls 8 and 9 which are designed as double-armed pivot levers.
  • the pawls 8 and 9 have opposing locking lugs 10 and 11, with which they engage in the example shown in the same recess 12 of the recesses arranged on the circumference of the locking disk 2.
  • the pawls 8 and 9 are arranged in parallel, but offset from one another and with mutually facing locking lugs, as can be seen particularly clearly from FIG. 3.
  • the locking disk 2 is equipped with recesses 12 arranged at 45 ° to one another and that recesses 16 are additionally provided on the radial circumference of the locking disk, which work together with a resilient locking device , which in the example shown consists of a gas pressure spring 17. In the example shown, this is connected with its free end, which engages in the recesses 16, to a pivot lever 18, which in turn is rotatably mounted on a pin 19.
  • a resilient locking device which in the example shown consists of a gas pressure spring 17.
  • this is connected with its free end, which engages in the recesses 16, to a pivot lever 18, which in turn is rotatably mounted on a pin 19.
  • the pawl 8 or 9 assigned to it is transferred into the release position, as is shown in FIG. 4 for the pawl 9.
  • the locking disc 2 can be pivoted counterclockwise, i.e. the turnstile can be freely rotated in this direction since the pawl 8 with its locking lug 10 cannot exert a locking effect in this direction.
  • a switching lug 20 (FIG. 2) provided on the circumference of the locking disk 2 with a switch 21 held stationary on the bridge 1 cooperates.
  • the pawl 9 Under the action of the return spring, tends to return to the locking position, but is prevented from doing so when its locking lug 11 rests on the locking disk 2.
  • the mentioned locking lug 11 of the pawl 9 arrives in the recess 12 that already comes under the locking lug at a small angle of rotation, so that the locking cross is completely locked in the 45 ° intermediate position.
  • the locking disk 2 via the locking lugs 10 and 11 and the locking pawls 8 and 9, only transmit forces acting in the longitudinal direction of these locking pawls to the bearing blocks 6 and 7, which can be made relatively solid and thus capable are also able to absorb large forces. No force is exerted on the rotary magnets 13 even when attempting to turn the turnstile by force.
