Definitions

  • the present invention relates to a strike for locks, which has technical features especially suitable for multipoint locks that have a front portion fastened to the frame of a door including the lock and which has at least one row of through holes for bolts of the lock, very close to a recess defined in the front portion and suitable for receiving the latch of the lock when the door is closed.
  • the box of the strike extends towards the side of the front portion that does not have through holes for the bolts, providing the necessary space to house the coil, the terminal block for electrical connection and part of the mechanical locking system.
  • the front portion of the latch transmits the forces to the base of the latch by means of the screws and the contact surface. Then, the base of the latch transmits the force to an intermediate area of the long lever which, in turn, transmits it to the short lever. Lastly, the force is transmitted to the box by means of the shaft of the short lever.
  • the latch exerts force on the long lever (in an upwards motion) and this lever pulls the short lever, which in this case blocks the movement and works by traction.
  • the short lever moves, unlocking the strike; once the force is no longer exerted, it returns to its initial position by the action of springs.
  • the holes defined on both sides of the recess of the front portion are not symmetrical, since on the side of the front portion that does not have through holes for the bolts, the holes for fastening to the front portion are vertically aligned since they have no limit with regard to space, while on the side of the front portion provided with through holes for the bolts, the holes for fastening are not aligned, since the lower hole is displaced towards the recess of the front portion so that it does not coincide with the through hole for the bolts that is closest to said recess.
  • the technical problem raised is the development of a strike that is able to interchangeably fit in multipoint locks mounted on doors that open to the right or to the left, without the risk of interference with the bolts that are housed in the holes of the front portion to which the strike is fastened and to allow the coupling thereof to the fastening holes defined in a specific front portion, or in the aforementioned existing front portions that have, on one side of the recess of the front portion, two vertically aligned fastening holes and, on the opposite side, two vertically unaligned fastening holes.
  • the symmetrical strike for multipoint locks of this invention is of the type that comprises: a box, a locking and unlocking lever system of a hinged front latch, a drive coil of the lever system towards an open position, and mounting holes for said strike in a front portion of a multipoint lock provided with: a recess for receiving a latch of the lock, mounting holes for the fastening means of the strike with the hinged latch facing said recess and through holes for bolts of the multipoint lock, close to any one of the sides, or the two sides, of said recess.
  • This strike has technical features that allow it to be mounted on front portions of locks on doors that open to the right or to the left, in other words, both on front portions that have through holes for bolts on one side or the other of the recess for receiving the latch of the lock, or on both sides of said recess.
  • Another object of the invention is to provide said strike with features that allow it to be fastened to the holes of the front portion, regardless of whether said holes are vertically aligned or unaligned.
  • the box of the strike comprises two symmetrical sides with respect to a median plane of the box and of the front latch of the strike, said symmetrical sides being arranged between the through holes for the bolts, located on any one side, or on the two sides of the recess of the front portion of the lock, and the corresponding side of said recess, which allows it to be used in multipoint locks for doors that open to the right or to the left.
  • This solution entails a reduction in the length of the strike with respect to strikes currently used and, therefore, the development of a compact drive mechanism.
  • the symmetrical sides of the box have an inward geometric shape, adapted to the contour of the through hole for the closest bolts and corresponding to the same side; said inward geometric shape defining an area of non-interference with regard to the box with the bolts.
  • This inward geometric shape can have a configuration that is concave curved, polygonal, stepped, oblique or any other suitable configuration for defining on the symmetrical sides of the box: a first laterally protruding end, in which first holes for mounting first fastening elements to the front portion of the lock are defined, and a second laterally inward end in which second holes for mounting second fastening means to the front portion of the lock are defined.
  • the first holes and the second holes are symmetrically arranged with respect to the median plane of the box and vertically unaligned, in a direction parallel to said median plane, given that the second holes are closer to the recess of the front portion of the lock; having envisaged in this case the use of a specific front portion that has holes with the same arrangement, in other words, symmetrically arranged with respect to the median plane of the box and vertically unaligned.
  • the strike of the invention has features that allow it to be adapted to this type of existing front portions.
  • the box of the strike comprises cavities that open laterally, which perpendicularly intercept the second holes of the box and which are suitable for occasionally housing a positional adapter provided with: a first hole for fastening to a second hole of the box by means of a pin, and a second hole for mounting the second fastening means to the front portion of the lock.
  • This positional adapter allows a second hole to be defined in any of the sides of the box, displaced towards the outside of the box and vertically aligned with the first hole on the same side of the box, and which the strike can fasten to the already existing front portions, which have two vertically aligned holes arranged on one of the sides of the recess.
  • Figure 1 shows an exemplary embodiment of the symmetrical strike (1) of the invention which is provided with a box (11) containing a locking and unlocking device for a hinged latch (12) for retaining or releasing a latch of a multipoint lock (not shown), and which is intended to be mounted on a specific front portion (2) of the multipoint lock, as shown in Figures 2 to 4 .
  • the front portion (2) of the lock has a recess (21), as is common, for receiving a latch of the lock and through holes (22a, 22b) for the bolts of the multipoint lock, arranged on any one of the sides of said recess (21), as shown in Figures 2 and 3 , or on both sides of the same, as shown in Figure 4 , the first of the through holes (22a, 22b) being very close to the mentioned recess (21).
  • the strike regardless of the position of the through holes (22a, 22b) for the bolts, comprises two symmetrical sides (11a, 11b) with respect to a median plane (Y) of the box (11) and of the latch (12), the box (11) being dimensioned so that in the mounting position on the front portion (2), said symmetrical sides (11a, 11b) are arranged between the through holes (22a, 22b) for the bolts, located on any one of the sides, or on the two sides of the recess (21) of the front portion (2), and the corresponding side of said recess (21) of the front portion (2).
  • the symmetrical sides (11a, 11b) of the box (11) have an inward geometric shape, adapted to the contour of the closest through hole (22a, 22b) and corresponding to the same side; and which defines an area of non-interference with regard to the box with the bolts.
  • this inward geometric shape can have different configurations, for example: concave curved, polygonal, oblique, oblique-stepped or stepped at an angle, respectively, although these shapes are not limiting.
  • the aforementioned geometric shape defines a first projecting end (13a, 13b) and a second inward end (15a, 15b), in which first mounting holes (14a, 14b) and second mounting holes (16a, 16b) are defined, respectively, for mounting fastening screws to the front portion (2) of the lock.
  • first holes (14a, 14b) and the second holes (16a, 16b) are arranged symmetrically with respect to the median plane (Y) of the box; vertically unaligned, the specific front portion (2) having first holes (23a, 23b) and second holes (24a, 24b) coinciding with those of the box (11) of the strike (1).
  • this strike can be mounted on front portions of multipoint locks for doors that open to the right or to the left, which have through holes (22a, 22b) on any one of the sides of the recess (21) of said front portion or on the two sides of the recess, as shown in Figures 2 to 4 .
  • Said cavities (17a, 17b) are suitable for occasionally housing, in any side of the box (11), a positional adapter (3), shown in Figure 8 in an unmounted position and in Figure 9 mounted in the cavity (17b) on the right side of the box (11).
  • Said adapter (3) comprises a first hole (31) for the fastening thereof inside any of the side cavities (17a, 17b) of the box by means of a pin (4) mounted through the corresponding second hole (16a, 16b); and a second hole (32) vertically aligned with the first hole (14a, 14b) on the same side of the box (11) and suitable for mounting the strike on a conventional front portion (2a) provided with a second hole (24c) vertically aligned with a first hole (23a, 23b).
  • This adapter (3) allows for the repositioning of current front portions existing on the market, and for defining on the box (11) a first mounting hole (31), vertically aligned with the hole (14a) and the second mounting hole (32), vertically aligned with the hole (14b) and, therefore, the mounting of the strike on front portions (2a) that have a second hole (24c) that is vertically aligned with any one of the first holes (23a, 23b) as shown in Figures 10 and 11 .
  • this strike comprises a terminal block assembly (6) that avoids any interference of the terminal block for electrical connection with the path of the bolts, and a lever system (71, 72) suitable for being housed in a box (11) with a reduced size, without said levers having to withstand considerable force when pressure is applied to the latch.
  • this strike comprises a terminal block assembly (6) with a length that is equal to or less than that of the box (11), represented in a mounted position in Figure 12 , and which comprises a base support (61) provided with anchors (66) for the coupling thereof to the rear area of the box (11) of the strike, and on which a terminal block (62) with a PCB (63) and a coil (64) with the corresponding coil support (65) are mounted.
  • the terminal block (62) with a PCB (63) is initially coupled to the base support (61). Then, the assembly shown in Figure 15 is mounted on said base support (61), the assembly being formed by the coil (64) and the coil support (65), to obtain the mounted terminal block assembly (6), as shown in Figure 12 , such that said coil (64) is arranged in a gap defined behind the latch (12) and which is practically the same length as said latch (12).
  • Figures 16 and 17 show the mounting of the terminal block assembly (6) in the rear area of the box (11) of the strike.
  • the lever system (71, 72) shown in Figures 18 to 20 comprises a short lever (71) and a long lever (72) mounted on rotary shafts (73, 74) and resting on a plane located above the coil (64), the short lever (71) having a lower extension arranged in the path of a movable core (64), referred to in Figures 21-23 , of the coil (64) in charge of the actuation thereof.
  • the base of the latch (12) makes contact with the long lever (72) in one area (75), referred to in Figure 20 , very close to the rotary shaft (74) of said long lever (72), and said long lever (72) acts against the free end of the short lever (71) such that said short lever (71) works by compression, unlike current models in which it works by traction.
  • the base of the latch (12) and the long lever (72) have a contact area (75) very close to the rotary shaft (74) of the long lever (72).
  • the difference between the distance (d) existing between the contact area (75) and the shaft (74) of the long lever (72) and the distance (D) existing between said shaft (74) and the contact area of the long lever (72) and the short lever (71) makes it so the force received by the short lever (71) is considerably reduced.
  • this strike incorporates an automatic system (8) represented in different positions in Figures 21, 22, 23 and which acts directly on the core (64a) of the coil (64).
  • This automatic system instead of acting on the long lever (72), comprises a band (81) riveted to the box (11) and a lever (82) assembled inside the latch (12) and resting against the band (81).
  • the lower part of the aforementioned lever (82) is in charge of making contact with a microswitch sensor (84) that monitors the open or closed state of the door.
  • a microswitch sensor (84) that monitors the open or closed state of the door.
  • this strike has an additional feature that consists of the incorporation of a top cover (5) that has in the centre, above the latch (12), a projecting portion (51) that prevents said latch (12) from hitting the frame of the door during the retraction thereof to the open position.
  • This projecting portion (51) of the cover furthermore allows the front portion of the latch (12) to be adjusted a few millimetres in height, as shown in the aforementioned Figures 24 to 27 .
