Definitions
- the invention relates to an unlocking device Landing doors of lifts, according to the generic term of Claim 1.
- the shaft doors of an elevator are closed Condition locked with the door frame, being usually a Locking lever rotatably attached to the shaft door with a locking member attached to the door frame in Intervention is.
- the locking lever by one mounted on the elevator car Unlocking mechanism unlocked.
- a locked landing door from the floor can be opened by an authorized person, too what purpose unlocking devices are provided.
- a Device for emergency unlocking of elevator doors becomes a swivel on one with the Hanger carriage of the support plate connected to the shaft door stored hook bolt is provided.
- the hook bolt is formed as a double lever, one lever arm one Has hook and the other lever arm with a weight is provided so that the hook is always pushed upwards becomes.
- the hook engages in a recess a stationary anchoring element, so that a sideways shifting of the trolley or the shaft door not possible.
- the Trigger bar is on a rotatable rotary lever attached by means of a tension spring in the Locked position is held.
- the rotary lever is with connected to one end of a Bowden cable, the other end is attached to a pull lever of an actuating element.
- the actuator is at the bottom of a Visual fighter arranged and from the hallway of the building accessible.
- the invention has for its object one over the Simpler unlocking device described above propose.
- the locking lever protrudes here an unlocking slide with an actuator in operative connection.
- the unlocking slide exists only from one piece and is directly from one Carrier sheet held and guided.
- the actuator has an actuator rotatably mounted on the carrier plate on, which is rotatably connected to a spindle which with is provided with a non-self-locking high helix thread. On the spindle is guided on a spindle nut on which the Unlocking slide is attached.
- 1 to 3 with 1 is a with the door frame Shaft door connected support plate, on which a Locking member 2 is attached.
- a locking lever 3 is not rotatable about an axis 4 on one Shown carriage of the landing door shown.
- the Locking lever 3 in the form of a double lever, instructs the one lever arm 5 a hook 6, while on the another lever arm 7 a weight 8 is attached. In locked condition is under the influence of weight 8 the one lever arm 5 raised and the hook 6 with the Locking member 2 in engagement.
- a Bolt 9 attached on the other lever arm 7 of the locking lever 3 .
- a Unlocking slide 10 is arranged, which is slidable on Carrier sheet 1 is guided and held tight.
- a cutout 11 is provided in the carrier plate 1 and the carrier plate 1 at the level of the cutout 11 through twisted twice at obtuse angles so deformed that the unlocking slide 10 only on one side of the carrier plate 1 and then performed on the other side becomes.
- a lower part 10.1 of the unlocking slide 10 is wider than an upper part 10.2 of the Unlocking slide 10, being at the upper corners of the lower part 10.1 and the upper part 10.2 friction-reducing pads 12, 13, 14 are provided.
- the Unlocking slide 10 is at its lower end an actuator 20 connected.
- the actuator 20 has a triangular provided actuator 21, which in a Carrier plate 1 mounted bearing plate 22 rotatably mounted is.
- the actuator 21 is with a spindle 23 non-rotatably connected, preferably with a single or multi-course two-course - non-self-locking Steep thread, for example trapezoidal thread, is provided.
- a spindle nut 24 seated on the spindle 23 is also included the unlocking slide 10 screwed so that when Rotating the actuator 21 by means of a Triangular key of the unlocking slide 10 upwards pushed against the bolt 9, the locking lever 3 is pivoted and the shaft door is unlocked.
