  • FIG 14 a seventh embodiment is shown, in which the previous lock (1) is combined with the U-shaped strike.
  • the door begins to rotate, the lock also being in the open position, with the head (13) outside the box (1) and the anchor (13) in the rotated position with the rotating bolt (300) inside the the box (1).
  • the stem (13) comes into contact with the contact plate (31), beginning to enter the box (1), in doing so, the anchor should move back to become vertical, but in this embodiment the spring (16) maintains the cam unlocking (10) resting on the latch (7), so the anchorage (11) cannot rotate and thus the twistlock is kept retracted until the latch (7) can lower. A little before the door reaches the end of its travel the latch (7) can be lowered as it remains behind the contact plate. At this time it goes down and allows the stop (38) to go down as well.
  • the stop (38) being in its low position, prevents the contact plate from moving backwards since it collides with the latch stop (38) in the final area of the window (390).
  • the movable stop (42) 180 degrees, we make the plate (40) position just above the stop (38), preventing the door from opening from the outside and inside, neither with the key, nor from the inside with the handle, as it does not allow the latches to rise, thus blocking the entire lock. This is important so that if a person who is inside does not want to allow entry to anyone, by turning the movable stop, no one has access from the outside.
  • the lug (104) of the unlocking cam (10) pushes the twistlock stop (301) in the stop push zone (301a) raising the twistlock stop (301).
  • Keep turning the key and the area (101) of the unlocking cam (10) pushes the anchor (11) by turning it, which makes the twistlock (300) begin to enter the box (1).
  • the twistlock is completely inside the case (1).
  • the cam continues to rotate and finally pushes with the zone (103) the latch (7) lifting it. In doing so, it raises the stop (38) of the strike.
  • the strike spring (36) pushes the contact plate helping it to rotate. With a gentle push, the rotation of the contact plate (31) ends and the door is open.
  • the stop (38) that has a flange that is the one that acts as a stop against the contact plate (31) at the moment in which both plates have approached, said flange rests on the lower part of the window (39). In this position, the head (13) has emerged, which by means of the spring (15) and the cover (14) push the anchoring cam (11) and keep it while the door is open in the position of figure 11.
  • the rotating bolt (300) blocks both the stop (38) and the latch (7) and its forcing is very difficult since it requires bending the front flange (33) to gain access and also the stop (38) is behind the contact plate (31), so that its forcing is not easy.
  • the opening is carried out without great efforts on the key, since all the parts that intervene are rotatable with respect to an axis, so their movements do not require efforts.
  • the spring of the twistlock stopper (306) is very weak, it should only force the twistlock stopper (301) to rotate until it rests against the bolt stopper area (300a) of the twistlock (300). It would really go down by gravity, but we must ensure its rotation with a small spring. The same happens with the spring (16) of the unlocking cam
  • the efforts of the key in the turn are staggered, first the anchor spring (17) is forced, which does not need a great effort to move the rotating stop (300) and the anchor (11), and when the turn has finished from the anchor (11) the latch (7) begins to rise, which does require a somewhat stronger spring, but at that moment the unlocking cam (10) supports most of the force of the anchor spring (17). Therefore, the effort to be made on the key is little more than that required to raise the latch (7). This is one of the great advantages over current locks, which in the case of being multipoint usually require 2 to 5 turns of the key to close the various locks on the door.
  • the striker spring (36) when the door is closed acts as a damping of the blow and when the door is opened it facilitates the opening since it tends to bring the two strike plates closer together, facilitating the opening.
