Definitions

  • the following patent refers to a lock for elevator doors, being of the type of lock that causes the locking of the door and the unlocking of the door is produced by means of a pin that the elevator car door has, a pin that actuates a pair of pulley-wheels causing the rotation and unlocking of the latch in order to permit the rapid carriage to be conveyed, in such a way that the lock assembly has a strip integral to the support plate, with respect to which the harpoon tip-shaped latch locks and whose locking strip has an inclined plane in the front position which the latch element abuts against and slides on in the event of being actuated by hand in an emergency.
  • the latch element has a counterweight and at the other side the latch element has an adjustable part having the pair of locking pulley-wheels of the pin of the elevator car door.
  • the lock that is presented is useful to be assembled in elevator doors with telescopic or central leaves, in which case a second anchoring hook is included in order to block both carriages, as it is conventionally known.
  • the lock for elevator doors is applicable in elevator doors with telescopic or central leaves that lock in their closing and the unlocking thereof being carried out by means of the pin that the elevator car door has.
  • elevator doors have a lock device that carries out the locking or blocking of the door in its closed position, whose lock body is rotatable with respect to a shaft and it has a blocking element with respect to a body fastened to the mechanism support plate, as well as a counterweight which keeps it in position.
  • the blocking element fastened to the support plate is defined by a harpoon tip-shaped body that faces the latch body locking with respect to the recess existing in the horizontal projection.
  • the present specification describes a lock for elevator doors, being of the type of lock that carries out the locking or blocking of elevator doors and the unlocking or unblocking of the doors is carried out by means of a pin that the elevator car door has and whose lock is assembled in the rapid carriage to which the corresponding leaf of the door is anchored.
  • the lock comprises an assembly defined by a locking strip fastened to the support plate, that in the front position has an inclined plane.
  • the assembly is also defined by a lock body rotatably connected to the rapid carriage.
  • the lock body is defined by a laminar-shaped latch element, a counterweight integral to the latch element at one of its sides, and a part with an omega ( ⁇ ) shaped profile with right angles connected to the latch element at the other side, by means of screws passing through respective elongated holes.
  • the latch element Upon actuating the lock body by hand, the latch element can slide and can be guided along the inclined plane protecting the electric contacts.
  • Figure 1 shows a view of the lock rotatably assembled in the rapid carriage which is in the blocking or locking position with respect to the strip fastened to the mechanism support plate, showing how the part having the pulley-wheels actuating the pin of the elevator car door is assembled with respect to a pair of elongated holes that permit its position to be adjusted.
  • Figure 2 shows a view of the lock rotatably assembled in the rapid carriage, represented in the preceding figure, in the position that it takes when it is moved by the pin of the elevator car door since it locks between the pair of pulley-wheels, showing how the rotation of the lock has permitted the unlocking of the latch element with respect to the strip fastened to the support plate.
  • Figure 3 shows a side view of the lock body, showing the counterweight, the latch element and the adjustable part having the pair of pulley-wheels on which the pin of the elevator car door actuates, as well as the rotation shaft of the lock body with respect to the rapid carriage.
  • the rapid carriage (1) to which the corresponding leaf of the door is fastened includes the lock body, that is comprised by a latch element (2) that rotatably connects by the shaft (3) to the rapid carriage (1), the counterweight (4) and the part (5) that has two wings (6) at different heights in which the corresponding pulley-wheel (7) is assembled, in such a way that the part (5) is connected to the latch element (2), by means of a pair of screws positioned with respect to respective elongated holes (8), that permit the position of the part (5) to be adjusted in order to adapt it perfectly to the pin of the corresponding elevator car door.
  • the latch element (2) ends in a harpoon tip shape and at its opposite end it has a groove (8) in order for it to be guided by a fixed pivot (10), positioned with respect to the groove.
  • the latch element (2) is locked with respect to a strip (11) integral to the mechanism support plate (13), the strip (11) being the abutment of the latch as an end element of a front inclined plane (12), along which the latch element (2) slides, in the event of an emergency, with respect to the top spot (14) of the harpoon tip-shaped end, acting as a protective element of the electric contacts (17) in the locking thereof.
  • the pin of the elevator car door is positioned between the pulley-wheels (7), which are rotatably connected to the end wings of the omega ( ⁇ ) shaped profile with right angles and when the latch element opens, it will actuate the end wings causing the lock body to rotate with respect to the shaft (3). Then the doors can be opened by the conveying of the pin on the lock body which in turn conveys the rapid carriage (1), which by means of the corresponding transmitting cable conveys the slow carriage.
  • the pin In the closing and blocking of the door, the pin will convey the lock body until the latch element (2) is in respect to its blocking position, in such a way that when the pin releases the lock body the rotation of the lock assembly causes the latch element (2) to remain in the locking position, as shown in figure 1 of the drawings.
  • the lock body will be actuated by means of the strip (16) projecting over the hole (15) of the rapid carriage (1), in such a way that when the strip is actuated by hand by means of the corresponding tool the lock body will rotate to a position similar to the one represented in figure 2, so that the latch element (2) may be unblocked or else it can be moved in order to exceed the inclined plane (12) and in order to lock it with respect to the strip (11).
  • the cited latch element (2) will act as a protective element of the electric contacts (17) thus preventing possible knocks that may break them.
