Definitions

  • the invention relates to the locking arrangement of a movable member for closing an opening, such as a door, of the type comprising a housing preferably mounted on the fixed structure of the opening and enclosing a locking mechanism of '' a bolt device secured to the movable member and a remote control locking device intended to lock the locking mechanism in its locking position of said bolt device and comprising a movable locking element between locking and release positions of said mechanism, and a connecting device interposed between the locking device and the locking mechanism.
  • Locking arrangements of this type are already known, but they have the major drawback that the force which the locking arrangement can withstand is not high enough, that the housing is too bulky for certain applications and that the structure is too complex and requires too much installation space.
  • the object of the present invention is to propose a locking arrangement of the type described above, which no longer has the drawbacks which have just been stated.
  • the housing is produced in the form of an elongated housing in which the locking device, the connection device and the locking mechanism are arranged so as to be aligned in the axis of the housing, the element latch is movable parallel to the axis of the housing in a rectilinear reciprocating movement and the connection device is produced in the form of a multiplier gear comprising several pinions whose axes are parallel, perpendicular to the longitudinal direction of the housing and juxtaposed in this longitudinal direction of the latter.
  • the locking mechanism comprises at least one pair of locking jaws, produced in the form of rotary members around axes perpendicular to the longitudinal direction of the housing and offset in the direction longitudinal of the latter and each comprising at their periphery a portion shaped as a locking means of said bolt device, in cooperation with the portion of locking means of the other jaw, at least the rotary member adjacent to the multiplier gear having on a portion of its periphery, angularly offset from the blocking portion, a toothed sector meshing with the aforementioned multiplier device.
  • the other rotary jaw member also has at its periphery, angularly offset with respect to its blocking portion, a toothed sector which meshes with a toothed sector of another rotary member connected to the first jaw so as to rotate with it in the same direction and in synchronism.
  • the multiplier gear comprises a first pinion provided with two peripheral toothed sectors with different primitive spokes, the sector whose radius is smaller meshes with the toothed portion of the first jaw and the sector having a larger pitch radius meshes the teeth of a smaller pitch radius of a second pinion which has another peripheral toothing of a larger pitch radius adapted to drive in rotation a circular plate to which is eccentrically hinged a link device actuating the aforementioned locking element, if necessary by means of a third pinion having a toothing of a smaller pitch radius.
  • the locking arrangement according to the invention is illustrated in its application to a door structure, the opening of the latter then forming the movable closure member.
  • the opening and the frame of the door structure are indicated by the reference numbers 1 and 2 respectively.
  • the opening 1 carries a bolt device 3 secured to the opening and intended to cooperate with the locking mechanism 4 enclosed in a housing 5 which is fixed to the frame 2.
  • the housing 5 is of elongated shape and is formed by a first U-shaped profile 6 intended to form the bottom of the housing and a second U-shaped profile 7 which forms the cover of the housing and covers the bottom profile 6.
  • first U-shaped profile 6 intended to form the bottom of the housing
  • second U-shaped profile 7 which forms the cover of the housing and covers the bottom profile 6.
  • This profile are arranged aligned in the axis of the housing, the locking mechanism 4 of the latch device 3 when the door is closed, a locking device 8 adapted to lock the mechanism 4 in its locking position and a connecting device 9 disposed between the locking device 8 and the locking mechanism.
  • This device 9 is configured to multiply the locking force produced by the locking device 8 at the locking mechanism 4.
  • the locking mechanism 4 comprises a pair of locking jaws bearing the references 11 and 12 respectively.
  • the jaws are in the form of circular discs each with a radial projection 13 provided with a notch 14.
  • Each jaw is pivotally mounted around a pivot 15 fixed at its ends in the bases of the bottom and cover profiles 6 and 7.
  • the two jaws 11 and 12 are laterally offset in the axis of the housing.
  • the two notches 14 which give the protuberances the general shape of a U have branches whose shapes are different in order to be able to perform different functions.
  • the branch 17 close to the side wall of the housing has the shape of a hook while the end of the other branch 18 has a substantially frustoconical profile.
  • the protruding parts 13 of the jaws overlap.
  • the two jaws 11 and 12 are arranged relative to each other so that, when the door is open, the ends of the two hook branches 17 are spaced from one another to allow engagement in the space 18 delimited by the notches 14 of the two zones in mutual overlap, of a bolt element 20 in the form of a loop of the bolt device secured to the door, through a window 21 in the front wall of the bottom section of the housing at the two ends 17 of the jaws. As shown in FIGS.
  • Each jaw 11, 12 carries on its peripheral part diametrically opposite to the growth 13 a toothed sector 22.
  • the locking mechanism 4 comprises a third locking jaw 24 which is pivotally mounted about an axis 25 parallel to the axes 15 and disposed in the same plane as the latter.
  • This third jaw also has at its periphery a toothed sector 26 identical to sector 22 of the two locking jaws of the bolt device.
  • the third jaw 24 is disposed on the side of the corresponding end of the housing and its toothed sector 26 meshes with the toothed sector 22 of the adjacent jaw 12.
  • the locking jaw 11 and the third jaw 24 are connected by a U-shaped driver 25 which constitutes a rod which extends substantially parallel to the walls of the bottom profile 6 and is articulated at its ends respectively near places of the periphery of the jaws 11 and 24.
  • the function of this coach rod is to synchronize in rotation the two jaws which it connects so that the jaw 24 can rotate the jaw 12, the latter then moving in the direction opposite of the jaw 11, but with the same angular speed.
  • the toothed sector 22 of the jaw 11 is adapted to actuate the connecting device 9.
  • This connecting device 9 comprises a multiplier gear formed by a train of three pinions 30, 31 and 32 and a set of three links 34, 35 and 36, the latter being articulated to the locking device 8.
  • the axes of rotation of the pinions are laterally offset in the axial direction of the housing and extend parallel to the axes of rotation of the jaws.
  • the articulation axes of the rods are also parallel to these.
  • the first pinion 30 comprises two toothed sectors 38, 39 concentric but with different pitch radii and diametrically opposite with respect to the axis of rotation 40.
  • the tooth sector with a smaller pitch radius has the same toothing module as sector 22 of the jaw 11 and meshes it.
  • the toothed sector 39 of a smaller toothing module and whose pitch radius is more large meshes a first toothed ring 42 of the second pinion 31.
  • This ring 42 has a relatively small diameter.
  • the pinion 31 comprises a second peripheral gear ring 43 of a larger diameter which meshes the teeth 44 of smaller diameter of the third pinion 32 which is integral in rotation with a circular plate 45 at the periphery of which is articulated the link 34.
  • This link is articulated at its other end to the link 35 which is produced in the form of a lever which pivots about a fixed axis 48. At the opposite end of this lever is articulated at 49 the link 36.
  • the link 34 is articulated to the lever 35 at a location 50 located between the pivots 48 and 49 of this lever.
  • the end of the link 36 is articulated to the locking device 8.
  • the locking device 8 comprises an electromagnet 51 whose movable core 52 is provided with a rod 53 which passes axially through the electromagnet, is movable parallel to the axis of the housing and enters a locking mechanism 54 which is controlled by the electromagnet 51.
  • This locking mechanism comprises a sleeve of rectangular cross section 55 mounted fixed in the housing.
  • This sleeve which extends parallel to the axis of the housing receives the hollow end 55, also of rectangular cross section, of a rod 56 which is articulated at 57 to the connecting rod 36.
  • a body 60 In the internal space of the end hollow 58 of the rod 56 is housed a body 60.
  • the latter is axially movable in its housing, against a return spring 61 which bears on the bottom of the cavity of the end 58.
  • the body 60 is fixedly mounted on the free end of the rod 53 of the movable core 52.
  • This body 60 of substantially rectangular cross section comprises on the side of the electromagnet 51 a portion 63 of dimensions complementary to those of the internal space of the rod 56 and a portion 64 located on the side of the spring 61 whose height is reduced relative to the height of the hollow space, symmetrically with respect to the median plane of the rod.
  • the two portions 63 and 64 are connected by a middle portion 65 which has inclined surfaces which constitute ramps each cooperating with a small body of revolution, namely a small roller 68.
  • a lumen 70 through which the roller can partially penetrate into an advantageously triangular notch 71 formed in the wall of the sleeve 55.
  • the arrangement according to the invention is equipped with a superlocking device 72 with independent circuit, which is located in the housing in axial alignment with the electromagnet 51 and is designed to be able to block the movable core thereof.
  • This superlocking device 72 essentially comprises an electric motor 73 whose rotary output shaft 74 extends parallel to the axis of the housing and carries at its end an intermediate piece 75 which is rotationally integral with the output shaft 74 and carries at its free end a diametrical pin 76 which engages in an axial recess 78 in the form of a slot which passes diametrically through a screw 80.
  • the screw is rotationally integral with the intermediate piece 75 and thus with the output shaft 74 of the motor and axially movable relative to the latter.
  • the screw 80 passes axially through a nut 81 which is fixedly mounted in the housing, cooperating with the internal thread of this nut.
  • the end 82 of the screw which moves axially in response to the rotation of the output shaft of the motor is adapted to lock the mobile core 52 in its retracted position in the electromagnet 51.
  • the end 82 of the screw 80 allows the movable core 52 to come out of the magnet to occupy its position shown in FIGS. 2 and 5.
  • the screw 82 includes a flange 83 which allows the actuation of two contacts 85 and 86 of the end of travel of the screw 80.
  • the latch device 1 To close the door, that is to say to pass from the state shown in FIG. 2 to that shown in FIG. 1, the latch device 1 is pushed into the space formed by the notches 14 of the jaws of blocking 11, 12. Under the effect of this device, the blocking jaw 11 rotates in the direction of arrow F1, the jaw 12 in the direction of arrow F2, this rotation being effected at the same angular speed as that jaw 11, but in the opposite direction.
  • This rotary movement of the jaw 12 is provided by the jaw 24 which moves in synchronism with the jaw 11.
  • the latter causes the pinion 30 to rotate in the direction of the arrow F3 which on the other hand causes the pinion 31 to rotate according to the arrow F4.
  • the pinion 31 rotates the pinion 32 in the direction of the arrow F5.
  • This pinion being integral in rotation with the plate 45 to which the link 34 is articulated, the rotation of the pinion causes the rectilinear axial displacement of the rod 56 of the locking device, via the links 34, 35 and 36.
  • the rotation of the locking jaw 11 of the locking device 4 at an angle of 60 ° causes the pinion 32 and the hinge plate 45 to rotate at an angle of about 350 °, in the direction of arrow F5.
  • the rod 56 performs a back-and-forth movement which is symbolized by the arrow F6 and, due to the pivoting angle of 350 ° of the plate 45, stops in the position shown in Figure 1 in which the rod is fully inserted into the sleeve 55 of the locking device.
  • the locking arrangement according to the invention makes it possible, by playing on the difference in the primary teeth diameters, to increase the amplitude of rotation of the jaws and therefore to reduce the force of traction on the locking element, to obtain a high yield and precision of movement and thus to reduce noise and to avoid adjustment systems for positioning and to reduce the size of the arrangement.
