Definitions

  • the present invention relates to a multi-point lock, of the type comprising several locking bolts retained in respective housings, intended to be mounted in distinct locations along the edge of a door, one of these housings constituting a housing main which comprises a key actuating member of its bolt, while the other housing (s) each constitute a secondary housing whose bolt guided in translation through an opening made in a headrest uniting its front and rear walls, is movable by means of an operating rod coupled to the bolt of the main housing, to be placed and immobilized, either in a locking position in which it is extracted from the headrest, or in a position unlocking in which it is retracted substantially flush with the latter.
  • Such locks generally mounted on doors giving access to residential or professional premises, offer the advantage of ensuring reinforced locking, generally at three or five points, along the edge of the door while being actuated only from the main unit by a single key, of which all persons authorized to enter the premises have a double.
  • the present invention aims to remedy this drawback by proposing a multi-point lock of the type specified in the introduction which is characterized in that at least one of its secondary boxes contains a movable piece for locking its bolt in the locked position, maneuverable by means of a key actuator, such as a locking cylinder, independent of the operating rod.
  • the bolt can be blocked either directly or indirectly, for example by means of the rod.
  • the key actuator of the bolt blocking piece of the secondary housing has a different coding than that of the key actuator of the bolt from the main housing.
  • the occupants or permanent users of the premises, whose access door is equipped with such a lock may thus, being the only ones to be provided with a key compatible with the actuator of the secondary housing, condemn the bolt of the latter in its locked position, to, when they deem it necessary, prohibit access to the room to persons having only the key operating the main housing of the lock, such as cleaning staff or the concierge.
  • the bolt blocking part of the secondary housing is advantageously mounted movable in a direction transverse to the direction of sliding of the transmission part, between a retracted position and an advanced position, and comprises a front tooth capable, in the advanced position of said blocking part, of engaging in a notch of complementary shape to the transmission part, placed facing it in the position active of the latter.
  • the body of the locking piece has the form of a plate that guide means keep sliding, in its direction of movement, along one of the front and rear walls of the housing.
  • said guide means comprise, on the one hand, one or more projections formed on one or the other of the opposite faces of the blocking plate and of said wall of the housing. and engaging in a sliding groove formed in the second of these faces and, on the other hand, a spring leaf which, on one side, bears on the housing and, on the other, is applied against the opposite free face of the blocking plate.
  • the spring leaf bears on the housing at the rear of the blocking plate and has, at its opposite free end, a small boss which, in the retracted position of the plate. is placed in front of the front edge of the latter and, in the advanced position of the plate, snaps into a hollow formed on its free face.
  • the blocking plate is automatically immobilized in its two extreme positions, the spring leaf further producing a click signaling that one or the other of these positions is reached.
  • the leaf spring oriented on an axis substantially parallel to the direction of movement of the blocking plate, bears on the wall of the housing against which it is held, by a pillar which, in the retracted position of the plate, is placed inside a cutout of the latter, opening on its rear edge.
  • the locking tooth being positioned on an axis substantially parallel to the direction of movement of the insert and the latter cooperating, by a lateral edge, with its member actuation, the projections and the associated sliding groove are provided between this lateral edge of the insert and the positioning axis of its locking tooth, while the spring leaf is applied to the insert on the other side of this axis.
  • the transmission part itself preferably has the form of a plate which, on the side looking at the blocking plate, has a raised lateral wing, by which it mates with the locking bolt, said lateral wing raised being secured, by a connecting veil, to a base part by which the transmission plate is guided to slide along the wall of the housing on which the blocking plate slides, the notch of said transmission plate being defined by an opening in the latter, straddling the axis along which its base part attaches to its connecting veil to the raised lateral wing.
  • FIG. 1 shows a multi-point lock, of the mortise type, which, in a manner known per se, comprises a main housing 1 embedded in the edge of a door P, substantially at the mid-height thereof, as well as two secondary boxes 2,3 mounted in the same way, one 2 at the top and the other 3 at the bottom of the door P.
  • the three boxes 1, 2 and 3 are provided, flush with the edge of the door, of a common headrest 4 covering the entire height of the latter.
  • the main housing 1 contains a conventional lock mechanism, with a U-bolt 5 capable of being actuated by a stand 6 and a dead bolt 7 whose movement is controlled by a key locking cylinder 8, the bolt 7 being here engaged, in the locked position, in preventing a strike from the vertical frame D of the door P.
  • FIG. 2 The internal mechanism of one of the secondary boxes, namely the upper box 2, is itself illustrated by FIG. 2, which first shows the traditional deadbolt for locking 9 guided in translation between the rear wall 10 and the front wall 11, here torn off, of the housing 2, in a direction substantially perpendicular to the plane of the headrest 4, of which a guide opening 12 is closely traversed by the head 13 of the bolt 9.
  • the tail 14 of the bolt 9, entirely contained inside the housing 2, is for its part provided with an oblong lumen 15 of constant width, tilting at an angle of 45 ° relative to the vertical and oriented so to approach the headrest 4 from its upper end.
  • This lumen 15 engages, with minimal clearance, a cylindrical stud 16 projecting from a plate 17, located between the tail 14 of the bolt 9 and the rear wall 10 of the housing 2 and slidingly mounted on the latter and along the headrest 4, in a direction substantially perpendicular to the direction of translation of the bolt 9.
  • the sliding plate 17 is fixed to a vertical operating rod 18, while at its upper end 17b, it is integral a locking rod 19.
  • the plate 17 of the secondary housing 2 slides upwards during the lifting of the rod 18 and thus plays the role of a movement transmission part, thanks to its stud 16 which, by being forcibly moved in the inclined lumen 15 of the deadbolt 9, pushes the latter out of the headrest 4.
  • the deadbolt 9 is thus brought and immobilized in its locked position, inside a barrier of a keeper of the vertical frame D, when the plate 17 has reached its final active position shown in solid lines.
  • the plate 17 propels upward the rod 19 which, by its end shaped as a bolt, engages in a prevention of a keeper of the upper horizontal frame D1 of the door P ( Figure 1).
  • the same locking actions are exerted on the deadbolt of the lower secondary housing 3 and the associated locking rod 19a, by the downward movement of the second operating rod 18a.
  • the plate 21 On its front edge 21a looking at the movement transmission plate 17, the plate 21 carries a projecting tooth 22 centered on its axis X and slightly raised relative to the inner face of the wall 10 of the housing while being substantially parallel thereto.
  • the secondary housing 2 is further provided with a traditional double locking cylinder with key 23 supported by the rear and front walls 10, 11 of the housing 2, just below the plate 21.
  • FIG. 4 it can be seen that the guide of the plate 21 is ensured by two tabs 27, 28, formed by a puncture, which engage, with minimal lateral play, in an oblong slot 29 of the rear wall 10 of the housing, with an axis parallel to the sliding direction X of the plate 21.
  • FIG. 3 also shows that these guide tabs 27, 28 are arranged between the lower wing 26 of the plate 21 and the 'median longitudinal axis X of the latter.
  • a leaf spring 30 fixed on a pillar 31, of short height, integral with the rear wall 10 of the housing. From this point of support, the spring leaf 30 extends forward, on an axis substantially parallel to the sliding axis X of the plate 21, to push the latter against the wall 10 of the housing, by its free end provided with a small internal boss 32, formed here by a stamping.
  • the plate 21 has, in its upper rear corner, a cutout 33 located directly above the spring leaf 30, cutout through which the pillar 31 stands in the retracted position of the plate 21, shown in FIG. 4 and in phantom in Figure 2. From its support pillar 31, the leaf spring 30 has a length such that in this same retracted position of the plate 21, the boss end 32 comes to engage in front of the front edge 21a of the latter in order to immobilize it (FIG. 5).
  • the movement transmission plate 17 comprises, on the side of the plate 21, a lateral wing 34, raised relative to the internal face of the rear wall 10 of the housing 2.
  • This wing 34 on which stands the stud 16 and rests with sliding the tail 14 of the bolt 9, is connected, by a short veil 35 inclining slightly towards the plate 21, to a base part 36 provided with lugs 37 formed by punctures and engaging in sliding openings 38 of the wall 10 of the housing to guide the plate 17 in the direction A.
  • An opening 39 is made in the elbow 40 joining the base part 36 of the plate 17 to the web 35.
  • This opening 39 which defines a notch opening facing the front edge 21a of the plate 21, is positioned so as to be on the axis X of the latter, in the active position of the plate 17.
  • the notch thus defined has a width slightly greater than that of the front tooth 22 of the locking plate 21.
  • the plate 17 is also applied against the headrest 4 by a heel 41.
  • the blocking plate 21 When from its retracted position in FIG. 5, the blocking plate 21 is moved by the pivoting of the bit 24 towards the transmission plate 17 in the active position, its front edge 21a abuts against the inclined web 35 of the latter and its front tooth 22 engages closely in the notch 39, as shown in FIG. 4. In this way, the transmission plate is immobilized in its active position, consequently carrying out a locking of the dead bolt 9 in the locking position.
  • the immobilization of the plate 21 in its advanced locking position of FIG. 4 is ensured by the spring leaf, the boss 32 of which engages in a recess 42 of the free face of the plate 21.
  • a pivoting movement in the direction reverse of the bit 24 will bring the plate 21 into its retracted position to release the plate 17.
  • the bolt 9 can then be actuated normally from the cylinder 8 of the main housing 1 of the lock.
  • the same locking mechanism will be provided in the housing lower secondary 3, the position of the notch of the transmission plate 17 being simply shifted upwards, along the elbow 40 of the latter, relative to that of the notch 39.
  • the plate 17 will be provided with two notches thus offset 39.43 to be able to be indifferently mounted in the upper secondary housing or the lower secondary housing.
