  • WO2017008104 describes a magnetic field generator for use in a locking device for locking a door or window and an adjacent building element, including a permanent magnet; a housing portion for receiving the magnet; an adjustment mechanism for allowing the adjustment of the position of the magnet in the housing.
  • WO2020157628 describes a closing device for windows and doors comprising a striker, a lock and a front wall adapted to selectively assume a locking configuration and a retaining configuration.
  • the movement of the latch according to a closing direction is caused by the magnetic interaction between a magnetic abutment system and a magnetic closing system.
  • the present description relates to a latch device for closure of a sliding door or window in a lock with clamp, comprising a latch and a latch case with said latch on one face of said case, wherein the latch pivots between a retracted position in the latch case and a protruding position from the latch case; wherein the pivoting latch comprises a magnet arranged in the latch with a first magnetic pole oriented outwardly on said face to receive, preferably create, a magnetic repulsive force from a second magnetic pole, having the same polarity as the first pole and oriented opposite to the first magnetic pole, from another magnet placed in the lock so that the latch pivots from the retracted position to a protruding position to be locked by the clamp on approaching said lock.
  • the latch has an inclination of 20° with respect to the latch case when in the protruding position.
  • the position of the latch center of mass is located so as to cause a moment in the latch that causes the latch to rotate with respect to an axle, leading to the retracted position when no other force is exerted on the latch, namely repulsive forces by the magnets.
  • the latch center of mass allows this device not to use springs or other elements when the latch moves to the retracted position. It allows the latch to be correctly positioned inside the latch case, without protruding, even if it presents slight angular deviations in its application.
  • the latch pivots from the retracted position to a protruding position when the lock magnet is at a distance equal to or less than 4 cm.
  • the latch comprises an axle for pivoting the latch.
  • the axle is located in the latch case.
  • the latch comprises a recess for receiving and locking the clamp for locking the door or window.
  • the magnet is fixed to the latch by fixing means selected from screws or an adhesive.
  • the latch device is fixed for mounting in a door or window frame.
  • the latch device can be fixed directly to the door, i.e. the latch device is a device that is fixedly mounted in a door or window frame.
  • a lock with clamp for closure of a sliding door or window on a latch comprising a lock case for receiving said latch on one face of said case, and comprising a magnet arranged in the lock with a first magnetic pole oriented outwardly on said face to receive, preferably create, a magnetic repulsive force from a second magnetic pole, having the same polarity as the first pole and oriented opposite to the first magnetic pole, from another magnet placed on said latch so that the latch pivots from the retracted position to a protruding position to be locked by the clamp on approaching said lock.
  • said lock comprises a knob so that the clamp moves from a retracted position to a locking position. More specifically, the user presses the displaceable knob which comprises an axle to interact with the clamp, causing the clamp to move into the recess of the latch and thereby lock the latch and lock the sliding door or window.
  • the knob comprises an axle and the clamp comprises a fork to receive said axle for the knob to move the clamp from a retracted position to a locked position, and vice versa.
  • the fork is at an end opposite to a portion of the clamp to lock the latch.
  • the knob is slideable.
  • the magnet is fixed to the lock by fixing means selected from screws or adhesives.
  • the lock with clamp is moveable for mounting on the door or window.
  • the lock with clamp can also be mounted on the door frame.
  • Another aspect of the present description concerns a closure for a sliding door or window comprising the latch device described above and comprising the lock with clamp described above.
  • the present description relates to a latch device for closure of a sliding door or window in a lock with clamp, comprising a latch and a latch case with said latch on one face of said case, wherein the latch pivots between a retracted position in the latch case and a protruding position from the latch case; wherein the pivoting latch comprises a magnet arranged in the latch with a first magnetic pole oriented outwardly on said face to create a magnetic repulsive force from a second magnetic pole, having the same polarity as the first pole and oriented opposite to the first magnetic pole, from another magnet placed in the lock so that the latch pivots from the retracted position to a protruding position to be locked by the clamp.
  • a lock with clamp comprising a lock case for receiving said latch on one face of said case, and comprising a magnet arranged in the lock with a first magnetic pole oriented outwardly on said face to create a magnetic repulsive force from a second magnetic pole, having the same polarity as the first pole and oriented opposite to the first magnetic pole, from another magnet placed on said latch so that the latch pivots from the retracted position to a protruding position to be locked by the clamp.
  • Figure 1 represents an embodiment of the closure wherein A represents the latch device; B represents the lock with the clamp and C and D are the actuators.
  • Figure 2 represents an embodiment of the closure comprising the latch device A and the lock with the clamp B.
  • Figure 3 represents an embodiment of the closure comprising the latch device A and the lock with the clamp B in exploded view, wherein 1 represents a nut, 2 represents the bridle, 3 represents a latch case, 4 represents the latch, 5 represents the frame fixing plate, 6 represents a screw, 7 represents the front of the lock, 8 represents an anti-friction element, preferably a polymeric tape, 9 represents the clamp, 10 represents the lock case, 11 represents an axle, 12 represents the magnet to be arranged in the latch 4, 13 represents a magnet to be arranged in the lock.
  • the anti-friction element allows friction and noise caused by the movement of the clamp to be reduced.
  • Figure 4 represents the operation of the present disclosure.
  • Fig. 4A shows the latch device A and the lock with clamp B in a spaced apart position.
  • the latch 4 is in the retracted position, being necessary to approach the lock with clamp B to carry out the movement thereof.
  • Fig. 4B shows the latch device and the lock with clamp in an approximate position, without locking. In this position, the latch 4 moves to the protruding position, rotating around the axle 11. More specifically, the movement of the latch 4 is due to the repulsion caused by magnets 12 and 13 (shown by arrows in opposite directions).
  • Fig. 4C shows the latch device and the lock with clamp in an approximate position, with locking.
  • the clamp 9 has been moved from an upper position to a lower position, as shown by the arrow, locking the latch 4, which is in the protruding position, preventing the movement of the lock with clamp B, which prevents the door from opening.
  • the movement of the clamp is carried out by the displaceable knob which comprises an axle 21 and that allows the movement of the clamp up and down.
  • the latch 4 when the lock with the clamp, comprising the fixing plate 7, is at a distance of more than 4 cm from the latch device A, the latch 4 is in the retracted position, the magnet 12 being parallel to the latch device 4.
  • the retracted latch position results from the latch center of mass which allows it to remain retracted in the latch case, since no magnetic repulsive force is present.
  • the magnet 12 of the latch device is in a position parallel to the position of the magnet 13 of the lock with clamp, so that the repulsive force between the magnetic poles of each magnet causes the latch 4 to pivot, allowing the latch to move to the protruding position.
  • the attachment of the magnet 12 to the latch 4 can be by screw 6 or by an adhesive material such as glue.
  • the latch 4 moves from a retracted position to a protruding position, due to the magnetic repulsive force between the magnet 12 of the latch device and the magnet 13 of the lock, causing the latch 4 to be inclined by 20° in relation to the latch case 3.
  • a clamp 9 is used that moves vertically guided in a case 10, which in turn is locked in the latch 4 that is installed in the frame of a door or in the frame of a window.
  • latch 4 comprises a recess for receiving and locking the clamp 9 and thereby locking the door or window.
  • the knob 18 comprises an axle 21 that moves the clamp to the latch lock or latch unlock position.
  • the clamp 9 comprises a fork for receiving the axle 21 of the actuation device D.
  • the actuation of the latch 4 is carried out through the use of magnets 12 and 13.
  • the latch 4 is actuated by magnetic forces caused by the magnets 12 and 13 which are positioned so as to cause the repulsion thereof.
  • the magnetic repulsive force causes the latch 4 to rotate around an axle 11, being projected to the outside only from that moment, leaving the latch 4 in the protruding position.
  • the latch system 4 together with the magnet 12 and the screw 6 or another fixing system such as adhesives, were developed in such a way that its center of mass causes its movement to the retracted position through gravity, thus avoiding the use of springs in the system.
  • the position of its center of mass guarantees that the latch 4 is correctly positioned inside the latch case, even if it presents slight angular deviations in its application. This change avoids the existence of protruding elements whenever the door is open.
  • magnets ensures that there is no rigid lockage in the event that the door or window is closed with the clamp 9 in the closed position, making the latch 4 recoil whenever they contact through the outer faces.
  • the polarity of the magnet 12 of the latch device is equal to the polarity of the magnet 13 of the lock with clamp, so that the magnetic repulsive force is created when the lock with clamp B is at a distance equal to or less than 4 cm from the latch device A and when the latch 4 moves. That is, the magnet 12 is with a first magnetic pole oriented towards the outside of the face of the latch case 3, to create a magnetic repulsive force from a second magnetic pole, having the same polarity as the first pole of magnet 13, with said poles being oriented in opposite directions.
  • the magnets can have any geometric shape, preferably round, square or rectangular.
  • Figure 5 represents the actuators of the lock with the clamp B, wherein C does not comprise the displaceable knob and D comprises the displaceable knob 18.
  • the displaceable knob allows the user to lock the door or window once that this knob is in contact with the axle 21 that will move the clamp 9 of the lock up or down, depending on the locking option of the latch 4 and unlocking of the latch 4.
  • Figure 6 represents an embodiment of the actuators of the lock in an exploded view, wherein 14 represents the front of the actuator D; 15 represents the plate for hiding the mechanism, 16 represents the base, 17 represents the positioning magnet, 18 represents a knob, 19 represents the cover, 20 represents a cover attachment screw, 21 represents an axle of the actuation system, 22 represents a fixing screw for the axle of the actuation system and 23 represents the plate to allow opening/unlocking from the outside.
  • Figure 7A represents an embodiment of the assembly of actuators C and D in the lock with clamp B.
  • the lock with clamp B is actuated by the vertical displacement of the displaceable knob 18.
  • Figure 7B represents an embodiment of the actuator D comprising the displaceable knob.
  • the displaceable knob 18 is produced in a material with magnetic properties, being attracted by the positioning magnet 17. This attraction ensures that the displaceable knob 18, once moved to the unlocked position, remains in this same position until an external force is exerted on the knob 18 to move to the locked position. While the knob 18 remains in the unlocked position, the clamp 9 remains in the upper position, preventing involuntary closing of the system.
  • Figure 7C represents an embodiment of the actuator D in the lock with clamp B.
  • the vertical displacement caused by the displaceable knob 18 causes the vertical displacement of the axle 21 and respectively of the clamp 9.
  • the movement between the axle 21 and the clamp 9 is carried out by the contact between the two elements, since the axle 21 is inserted in the clamp 9, in the area of the fork. This location allows the lock with clamp B and actuators C and D to be connected together without the need for fixing elements.
  • Figure 7D represents the opening of the lock with clamp B from the outside of the door, using actuator C.
  • the plate to allow opening from the outside 23 has a geometry that allows the passage of a coin, key, or other accessory of similar geometry to allow the vertical displacement of the axle of the actuation system 21, which allows the door to be opened from the outside in emergency cases.
  • the user activates the system by moving the knob 18 vertically, which transmits the movement to an axle 21 which is secured to the knob 18 by a screw 22.
  • the axle 21 is produced in a polymeric material in order to reduce friction and noise when in contact with the lock. This axle is mounted by the user according to the thickness of the door.
  • the knob 18 can have another displacement such as, for example, radial with respect to the axle, rotary, among others.
  • the actuator D has a magnet 17 housed in its structure in order to create the attraction of the knob 18, which in turn is made of a metal with magnetic properties. Once in the unlocked position, it is necessary to apply an external force to move the knob 18 to the locked position. This force gives the user the feeling of validation of the closure.
  • the plates to allow opening from the outside 23 can be exchanged for plates without slots, making it impossible to open the door from the outside in cases of greater security or even to market the product without an opening mechanism.
  • the movable components are guided in a polymeric base or shell, where the user can place his hand, never having contact between metallic components, in order to guarantee low noise and friction between them.
  • This component also has several cavities on the outside thereof to allow better placement of an adhesive or other fixing element to install on the door.
  • Figure 8A represents the approach of the latch device A with the lock with the clamp B, in the lower position, in which with the repulsive force from the magnets 12 and 13, the latch 4 is in the protruding position.
  • Figure 8B represents the lock B with the clamp 9 in the lower position, i.e., the locking position, and since the magnetic repulsive force from the magnets 12 and 13 causes the latch to protrude, the outer faces of the latch 4 and clamp 9 collide. However, the collision causes latch 4 to recoil. Latch 4 movement is only caused by the repulsion from magnets 12 and 13 and does not result from the action of mechanical elements, thus not damaging the various components when closing the door with the clamp in the lower position.
  • the arrows in Figure 9 represent the repulsive forces of the magnets since the poles are equal, said poles being oriented in opposite directions, causing the latch to move to the protruding position. That is, if the magnet of the latch device has the magnetic pole oriented towards the frame fixing plate, then the magnet of the lock will also have the same polarity oriented towards the front of the lock. For example, if the latch magnet 12 has the south pole oriented towards the face of the latch case, the lock magnet 13 will have the south pole oriented towards the outside of the lock. On the other hand, if the magnet of the latch device 12 has the north pole oriented towards the frame fixing plate, then the magnet of the lock 13 will also have the north pole oriented towards the front of the lock. This repulsion will promote the movement of the latch, causing it to move from the retracted position to the protruding position.
  • Figure 10 represents the latch 4 in the various positions, from the protruding to the retracted position.
  • Figure 10A shows the latch 4 in the protruding position and the respective force caused by the latch center of mass 4 at the moment wherein the lock with clamp B moves away and there are no longer magnetic forces acting on the latch 4.
  • the position of the latch center of mass 4 is located in such a way as to cause a moment in latch 4 that causes latch 4 to rotate in relation to axle 11, moving latch 4 to the retracted position, when no other force is exerted on latch 4, the use of springs or magnets being unnecessary for this function.
  • Figure 10B shows the moment caused in latch 4, starting its movement to the retracted position.
  • Figure 10C the latch 4 is shown in the retracted position and the respective force caused by the center of mass of the latch 4.
  • Figure 11 represents the lock with clamp installed on a door.
  • the clamp 9 comprises a fork, which allows an offset and respective decrease in the precision necessary for installing the actuation system.
  • the front of the lock 7 presents a geometry that allows the entry of the latch 4, even with misalignments in relation to the latch device A, without the need for adjustments in the door for the correct operation of the closure.
  • Figure 12 represents an embodiment of the lock alignments with actuation elements.
  • the movement between the axle 21 and the clamp 9 is carried out by the contact between the two elements, since the axle 21 is inserted in the clamp 9, in the area of the fork. This location allows the lock with clamp B and actuators C and D to be attached together without the need for fixing elements.
  • Figure 13 represents a top view of an embodiment of the closure, where the clamp 9 has a reduced thickness of, preferably, 2 mm, which allows the use of handles with a greater depth in relation to conventional lock systems.
