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 and below the turnstile, a rotatably mounted on the axis of the turnstile rotatably held locking disc with recesses distributed over its circumference and two locking members, which are held on the bridge part and are to be brought into and out of engagement with the recesses of the locking disk and are designed to lock in opposite directions, and controllable actuating magnets associated therewith 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 which interacts 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 work together 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 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 actuated, 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 actuated by force, so that exerted very large moments on the locking members will.
  • the invention has for its object to develop a device of the type mentioned in the introduction so that a considerably better protection of the turnstile against violent actuation is achieved while reducing the effort and a compact design is achieved.
  • the two locking members are each designed as double-armed pivot levers and equipped with oppositely acting locking lugs on the bridge around parallel to the plane of the locking disc axes of rotation and are mounted so that they with their locking lugs in the axial Engage in the direction in the recesses of the locking disc.
  • the locking members designed as double-arm pivot levers can be arranged above or below the locking disk, so that a compact construction and extremely short distances of the locking members for locking and unlocking are required, which in turn lead to corresponding magnets with relative short ways of anchors can be used. If an attempt is made to turn the turnstiles by force, the forces absorbed by the pawls are transmitted in the longitudinal direction of the pawls to the axes of rotation or bearing points running on the bridge, so that the pawls themselves the action of extremely large torsional forces on the turnstile are not deformed and no moments have to be transferred to the bearing points In addition, the locking members are protected above and below the locking disk and can be accommodated from the outside only with great difficulty. This also considerably improves the security value of the turnstile.
  • 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 immediately adjacent to one another in parallel and are arranged with mutually facing locking lugs so 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 rather are connected in a geared manner to the armatures of rotary 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 on the locking members, with 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 otherwise necessary springs acting 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 radially offset by 90 ° on the circumference for the engagement of a resilient latching device.
  • these recesses may be provided outside of the edge region of the locking disc so that derRand Scheme the lock plate for the additional offset on the circumference recesses for engagement of the resilient locking means available stands.
  • the arrangement of the recesses cooperating with the locking members 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.
  • the drawing shows an embodiment of the invention.
  • the fixed 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 in a rotationally secure manner on the axis 3 of the turnstile shown in FIG. 4.
  • 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 or stored.
  • 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 for mounting pawls 8 and 9, which are double arm-shaped swivel levers are formed.
  • 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.
  • actuate the pawls 8 and 9 serve on the U-shaped profile part 5 laterally above the mounting tabs 5a held rotary magnets 13, the armature of which is connected via a lifting linkage 14 or 15 with the pawls 8 and 9 in such a way that the rotary movements of the Armature of the magnets 13 on the ends of the pawls 8 and 9 facing away from the locking lugs 10 and 11 respectively.
  • Return springs are provided in the lifting magnets, which ensure that after actuation of the pawls 8 and 9 by the magnets, the pawls 8 and 9 are returned to the starting position.
  • the locking disc 2 is equipped with 45 0 offset from each other and that additionally 16 recesses 16 are provided on the radial circumference of the locking disc, which cooperate 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 becomes in transferred the release position, as shown in Fig. 4 for the pawl 9.
  • the locking disc 2 can be pivoted counterclockwise, ie 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 which already comes under the locking lug at a small angle of rotation, so that the locking lug is completely locked in the tS o intermediate position.
