Definitions

  • the present invention relates to a lock of the type intended to be embedded in the edge of a door, in particular of an interior communication door of living quarters, and comprising a dead bolt.
  • the depth of said trunk is however left to the freedom of the manufacturer.
  • Many current locks have a depth varying between 60 and 61 millimeters overall, that is to say counted from the external face of the headrest.
  • the difference in depth between the trunk and the gantry allows a possible planing of the edge of the door without hampering the positioning of the lock.
  • a gabant of this depth has the disadvantages of not always being easy to dig and, above all, when the door is constituted by a wooden frame surrounding a central panel, leading to a weakening of the wooden element in which it is provided, at the level of the lock.
  • these wooden elements generally include, on the inside, molded edges reducing their thickness and slots made in their thickness from their internal face for engaging the edges of the panel. Because of the width of said commonly used elements, the bottom of a 65 mm deep gabant is at the molded edges and in the immediate vicinity of the bottom of the slot.
  • These locks also each include a dead bolt, which can be actuated by a key or a button secured to a bit which can be operated from inside a room in the case of bathroom or toilet doors, as well as a piece called "throat".
  • the "groove” is movable vertically and is associated with a return spring keeping it in the low position in which a lug which it comprises is engaged in a notch formed in the upper edge of the body of the bolt. This engagement allows the immobilization in translation of the bolt.
  • the bit of the key or button comes to bear against the lower edge of the "groove” and lifts it to unlock the bolt in translation.
  • the bit engages in a notch formed in the lower edge of the body of the bolt and presses against one of its edges to move the bolt until introduction of the lug of the "groove” in another notch of locking in translation of the bolt.
  • the body of the bolt includes a projection on the side opposite the dead bolt forming a stop, which prevents the key, in the extended position of the dead bolt, from making an additional turn, which would unlock the dead bolt by again lifting the "groove” , and which is cleared in the retracted position of the dead bolt.
  • the depth of the trunk makes possible the existence of this projection and the stroke of the dead bolt prescribed by the standards.
  • the present invention aims to remedy the aforementioned drawbacks by providing a lock that does not require the digging of a gabant of 65 millimeters deep while meeting the standard and ensuring the locking of the dead bolt.
  • the lock to which it relates comprises a trunk the depth of which is approximately 50 millimeters and a finger with an axis perpendicular to the walls of the trunk, situated below the dead bolt and on the side of the headrest, this finger serving pivot axis to an L-shaped part that it crosses at the intersection of its branches, the smallest branch of the L, oriented vertically, being on the path of a lug that includes the body of the dead bolt, simply coming into contact with it at the end of the dead bolt outlet travel or moving it so as to rotate the L-shaped part, and the largest branch of the L, whose free end is located beyond the hole of the lock, comprising, at its free end a boss oriented perpendicularly at its axis and inwards, located when the dead bolt is in the retracted position, outside the trajectory of the maneuvering bolt of the dead bolt or capable of being erased when it passes over it but located when the bolt frame is in the extended position, on the path of the bit so as to constitute a stop preventing said bit
  • this lock overcomes the aforementioned drawbacks.
  • the gabant that it requires does not exceed 55 millimeters, so that its bottom is outside the molded edges of the wooden element in which it is hollowed, and at a distance from the bottom of its slot allowing the engagement of the edges of the central panel.
  • the boss of the large branch of the L-shaped part prevents, when the dead bolt is in the extended position, that the bit comes to raise the "groove” again and unlock the dead bolt.
  • the travel of the dead bolt prescribed by the standard can be obtained, and this, with an effective locking of the dead bolt in the extended position.
  • the lug which the body of the dead bolt comprises moves the small branch of the L-shaped part so as to rotate it and bring said boss on the trajectory of the bit, trajectory outside which it is located in non-pivoted position of the L-piece.
  • the weight of the largest branch of the L-piece is enough to return the latter to the non-pivoted position when the lug of the dead bolt does not press against its smallest branch and when the lock is vertical, but preferably elastic means for returning the L-piece to the non-pivoted position are provided.
  • These means can be constituted, according to a simple embodiment of the invention, by a pin spring engaged on the aforementioned finger, one of the branches of which is mounted at its end on the L-shaped part while the other is in abutment against a rivet tab on the nearby trunk lid.
  • the lug which the body of the dead bolt comprises comes into contact with the small branch of the L without moving it so as to prevent the erasure of said boss when the bit passes over it, the boss being normally maintained on the trajectory of the latter by elastic return means provided for this effect.
  • these means consist of a metal wire bent at 180 degrees in the middle, the end parts of which form two coaxial pin springs and the intermediate parts of which are bent over a portion of their length, the middle of the wire.
  • the springs being engaged on the aforementioned finger with support of the free ends of the wire against a rivet tab on the trunk lid located nearby, and a portion of the curved parts of the wire, located on either side of the L-shaped part and on the side opposite the boss relative to the keyhole, located on the trajectory of the bit, said curved parts being shaped so as to be able to be erased when passing over the bit when the key is actuated manually.
  • the lock mechanism is provided to allow it to be housed in its trunk of lesser depth.
  • the return spring of the follower is arranged parallel to the races of the dead bolts and half-turn, this spring being engaged on a rod which is integral, by one of its ends, with the front wall of the trunk and which is engaged, by its other end, in a sleeve allowing it to slide, secured to a slide on which a lug that includes the follower rests.
  • This lug, as well as that causing the movement of the latch bolt are each offset on one side of the axis of rotation of the follower so that the latch bolt has, despite the lack of space, the stroke prescribed by the standard .
  • the figures show a lock 2 called “mortise lock”, that is to say intended to be embedded in the edge of a door.
  • It includes a headrest 3, a trunk 4 whose overall depth is about 50 millimeters, a latch bolt 5, a dead bolt 6, a follower 7 and a keyhole 8 whose dimensions, strokes or positioning are comply with the standard applicable to this type of lock.
  • the "groove” 10 also includes a part called “groove” 10 in which are formed lights 11 and 12 allowing it to be vertically movable, lugs 13 and 14, cut in the wall of the trunk 4 and used for riveting the hood thereof , being engaged and sliding each respectively in one of them.
  • the "groove” 10 comprises a lug 15 projecting perpendicular from itself against which a helical spring 16 is in abutment, the other end of the spring 16 being in abutment against the tab 13. Two lower edges 10a of the "groove "10 are tilted.
  • the body 6a of the dead bolt 6 comprises two notches 20 and 21 formed in its upper edge and the bottoms of which have a shape corresponding to that of the lug 15, a slot 22 with a horizontal axis in which the tabs 14 slide, a notch 23, formed in its lower edge and situated on the path of the key bit of the lock, represented by the circle 24, as well as a lug 25.
  • a finger 30 with an axis perpendicular to the walls of the trunk 4 is located below the dead bolt 6 and on the side of the headrest 3.
  • This finger 30 serves as a pivot axis for an L-shaped part 31 which it crosses at level of the intersection of its branches.
  • the smallest branch of the L, oriented vertically, is on the path of the lug 25 and its largest branch, the free end of which is located beyond the keyhole 8, comprises, at its free end a boss 32 oriented perpendicular to its axis and inward.
  • the lock 2 also comprises an elastic means 35 of the return associated with the part 31. It is constituted by a metal wire bent in its middle 35a at 180 degrees, the end portions of which form two coaxial pin springs 36 and the intermediate portions 35b are curved over part of their length.
  • the middle 35a of the wire bears against the peripheral wall of the part 31 located on the opposite side to hole 8 and engaged in a notch 37 formed for this purpose in this wall.
  • the springs 36 are each located on one side of the part 31 and engaged on the finger 30 with support of the free ends of the wire 35, which form one of the branches of the springs 36, against one of the riveting tabs 40 of the trunk lid 4 located nearby.
  • the lock 2 also includes a spring 50 for returning the follower 7 disposed parallel to the races of the U-bolts 5 and of the dead bolt 6, this spring 50 being engaged on a rod 51, which is secured by one of its ends , of the front wall of the trunk 4 and which is engaged, by its other end, in a sleeve, allowing its sliding, integral with a slide 53.
  • the latter is U-shaped, between the lateral branches of which is engaged a lug 54 that includes the follower 7.
  • the slide 53 comprises two pins 55 sliding in slots 56 formed in the walls of the trunk 4.
  • the lug 54 as well as the lug 60 causing the movement of the U-bolt 5 are each offset on one side of the axis of rotation of the follower 7 so that the U-bolt 5 has, despite the small width of the trunk 4, the stroke prescribed by the standard.
  • the U-bolt 5 is integral with an axis 61, on which a return spring 62 is engaged and which is guided by lugs 63.
  • the lug 25 is shaped to come into contact with the small branch of the part 31 at the end of the stroke of the dead bolt 6 in order to immobilize said part 31 in pivoting.
  • the boss 32 normally maintained on the path of the bit 70 thanks to the springs 36 and disappearing when the latter passes over it, does not disappear when the bit 70 passes over it. It therefore constitutes a stop preventing the bit from making an additional turn which, by lifting the groove 10, would lead to an unlocking of the dead bolt 6.
  • FIGS. 4 and 5 show that, in addition, the curved parts 35b of the wire 35 or the boss 32, depending on the position of the key, prevent the bit 70 from coming in front of the hole 8 when the key is not actuated manually .
  • the key cannot fall out when the door moves or slams under the effect of a draft.
  • the part 31 is hollowed out at 71 so as to ensure the passage of the bit 70 in the hole 8. It also includes a recess 72 allowing its longest branch to maintain, at its free end, a sufficient width, the extremal edge thus delimited of this branch being engaged in a slot in the side wall of the trunk 4 in the non-pivoted position of the part 31 for reasons of lack of space.
