Definitions

  • the main invention relates to a method of strikes locks and bolts, adjustable, and fasteners cooperating with metal screws with inserts. Adaptable on wooden frames or metal frames. Said keeper being particularly resistant to break-in attempts with a crowbar lever.
  • the same process can be extended to improve the fixing of locks and locks on the doors.
  • the process which can be fitted with electrical contacts, triggers the alarm from the start of the attack on the door.
  • the manufacturers of locks have endeavored to improve the mechanics of locks and bolts.
  • the present invention aims to remedy these drawbacks by proposing an adjustable system, to obtain the opening adapted to the passage of the bolt.
  • This opening is delimited between a base sole; voluntarily oversized so as not to fall into the damage caused by the previous poses and deposits; and a robust force plate to receive the thrust from the bolt in the event of an intrusion attempt.
  • the force plate has undergone two holes along the same axis. Screws will pass through the main plate and join the sunk nuts, crimped on the base plate (or base plate). The correct spacing between them will be obtained by compression springs, inert, passive, crossed by the screws and covering the drowned nuts. The correct setting is obtained by screwing or unscrewing.
  • the force plate further comprises, an electrical contact And it is interposed between the force plate and the base plate two insulating plates, the closest to the force plate comprising a blade conductive, the second being in contact with the bolt. Any load by weighing transmits the force by the bolt which deforms the two insulating plates, bringing the conductive blade against the force plate establishing the circuit connected to a battery, to an alarm device. If we use traditional screws, now these penetrate completely, in healthy parts, not damaged by the previous screws, which represents with the adjustment possibilities, the solution to the bad problem of strikes; we can still improve the fixings on wooden or metallic frames by using metal screws which will cooperate with threaded inserts, these will be put in place, inserted, immobilized in or on the frame.
  • a first form of implementation of the method according to the invention consists in using, as threaded insert, a nut secured by any suitable means to a support having a drilling opposite that of the nut and a zone of weakness in the immediate vicinity of said nut, to practice, at the bottom of the fire -work, a mortise parallel to the face of the jamb to receive the strike, to pierce the jamb to allow the passage of a machine screw, then to break the said support after having "sinned" said nut, the zone of weakness provided facilitating the rupture, thus trapping the nut in place.
  • the nut can be secured to the support - which only serves as a maneuver extension by gluing, welding, stamping, or drilling in the mass.
  • a second embodiment of the invention consists in locking the insert in a direction perpendicular to the longitudinal axis of the machine screw.
  • the method consists in using as an insert, an elongated cylinder having a threaded longitudinal bore and a transverse hole, to be made in the face of the frame intended to receive the strike a first hole intended to receive said cylinder, to be made in the lateral face of the jamb, at the bottom of the rebate, a second hole adapted to receive a key capable of penetrating the bore transverse of the cylinder and immobilize it in rotation to allow the screwing of the machine screw while leaving said key in place.
  • the key is perpendicular to the longitudinal axis of the machine screw and prevents the tearing of the insert.
  • the method consists in using, commercial insert; an elongated cylinder having a longitudinal bore and a transverse bore, to be made in the face of the frame intended to receive the strike, a first hole adapted to receive the machine screw, to be made in the side face of the frame, at the bottom rebate, a second hole adapted to receive the cylinder, to temporarily fix an extension in the longitudinal bore of the cylinder, to introduce the cylinder into the second hole and, using the extension, to immobilize the cylinder in the desired angular position allowing the penetration of the machine screw into said transverse hole and removing the extension.
  • This extension allows the assembly and disassembly of the insert.
  • the extension can be fitted, welded, glued, etc., in the longitudinal hole. In a preferred form, however, the longitudinal bore is threaded and the extension screwed.
  • the process consists in using, as fixing screws, square screws, of which a first branch is threaded over its entire length, to pierce the frame to allow the introduction of the second branch of the bracket inside the hollow profile.
  • a lock comprises a trunk and a movable bolt having an active end capable of projecting from one of the sides of the trunk of the lock in order to penetrate the strike in the closed position of the lock; and an inactive end protruding from the side of the trunk opposite the strike.
  • the inactive end of the bolt is clamped by a bracket adjustable by compression springs and preferably fixed by bolting through the door.
  • This arrangement prevents that under the force of a lever, the lock box can untie or lift and that the lock / cylinder lock connection is distorted.
  • the stirrup which comprises, like the strike plate, a fixing sole extending beyond the displacement zone of the inactive part creating a reinforcement projection.
  • stirrup which comprises, a cover, like the keeper, made integral with the corresponding fixing sole by means of appropriate screws, said screws have a head forming a wheel.
  • the keeper according to the invention comprises a sole 1 adapted to be fixed to the frame 2 of the door and intentionally oversized to avoid the lacoYn- cidence of its fixing points with a doorframe area deteriorated by previous strikes and removals.
  • the sole 1 has a first pair of holes 3 intended to allow the passage of fixing screws 4, 4 ′ or 4 "and a second pair of holes 5 opening onto the internal face of the sole by a milling 6 adapted to receive the head. 7 of a sunken nut, the barrel 8 of which projects outwards from the sole 1.
  • a third pair of holes can be provided for traditional fixing to the frame, using wood screws, lag screws, wooden bolts, screws with metals, etc ... These fixing means penetrate their entire length into the wood of the frame in places which have not been injured by successive poses and deposits.
  • the keeper according to the invention further comprises a force plate 9 having a pair of holes 10 facing holes 5 of the sole 1.
  • This force plate is intended to receive the weighing in the event of an attempt to breaking in.
  • the spacing between the sole 1 and the force plate 9 is adjusted by means of compression springs 11.
  • an embellishment 12 having bores 13 facing the bores 10 and 5.
  • Des fixing screws 14 pass through the holes 13 and 10 and cooperate with the internal thread of the barrel 8 of the nuts.
  • the hubcap 12 is intended to conceal from view the force plate, the compression springs and the means of joining the force plate and the sole.
  • the force plate 9 and the sole 1 define between them an opening 15 for the passage of the bolt of the lock. Thanks to the compression spring 11, the width of this opening 15 is adjustable.
  • the fixing screw 4 cooperates with a nut 25. More specifically, it was made in the rebate of the jamb, at deeper of the latter -this which corresponds to the thickness of the mortise carrier 37 parallel to the face receiving the sole 1, said mortise 37 being adapted to receive a support plate 24 to which is secured by any suitable means, such as bonding , welding, screwing, nesting, stamping, etc., a nut 25.
  • the support plate 24 has a zone of weakness or notch 26 in the immediate vicinity of the nut 25.
  • the metal screw 4 engages with the nut 25, after which the support 24 can be broken at the level of the notch 26. It is understood that the support 24 only serves as an extender making it possible to immobilize the nut 25 while it is "fishing" with the screw 4.
  • the fixing screw 4 cooperates with a cylinder 18 which has been introduced into a hole 9 drilled in the face of the jamb intended to receive the sole 1.
  • the hole 9 is of course with a diameter slightly greater than the diameter of the cylinder so that it can penetrate and be oriented there easily.
  • the cylinder 18 has a first threaded longitudinal bore 20 and a second transverse bore 21.
  • a hole has been drilled allowing the insertion of a key 22 (see FIG. 5) into the transverse bore 21 to immobilize it in rotation when screwing the screw 4 '.
  • the cylinder 18 is deliberately set back relative to the free surface of the jamb to obtain a pulling effect by means of the screw 4 '.
  • a first hole was made perpendicular to the surface of the chamber 2 having to receive the sole 1 to accommodate the fixing screw 4 " and a second hole perpendicular and secanting to the previous one, from the side face of the frame 2, for the introduction of a cylinder 18 '.
  • the cylinder 18' has a first longitudinal bore 20 'adapted to receive an extension 23, and a second transverse threaded bore 21 'adapted to cooperate with the screw 4 ". It is understood that the extension 23 serves to immobilize the cylinder 18 'in the desired angular position to allow the insertion of the screw 4 "in the transverse bore 21'.
  • the extension 23 can be unscrewed, only the cylinder 18 'remaining embedded in the frame. It is also understood that the fixing can be dismantled by replacing the extension 23, by unscrewing the screw 4 ", and by extracting the cylinder 18 'from the hole in which it has been inserted.
  • a fixing screw 4 "' is used at an angle, the branch 27 of which is threaded over its entire length.
  • the metal frame 2' has a pair of holes 3 'for the passage of the second branch 28 of the screw 4 "'square.
  • the sole plate 1 could be fixed to the frame by the 4 "square screws, the plate force and the hubcap being fixed to the sole by a set of separate straight screws and cooperating with threads depending on said sole.
  • Figures 9 to 11 show the modifications to be made to the keeper according to the invention to make it an alarm keeper.
  • the keeper comprises, in addition to the elements indicated above, an electrical contact 31 in the force plate 9, a first insulating plate 32 furnished with a conductive blade 33 kept spaced from the force plate 9 by insulating spacers 34 and a second insulating plate 35 and contact with the bolt 36 of the lock.
  • the contact 31 and the conductive blade 33 belong to an electrical circuit C which incorporates a supply battery and a bell not shown.
  • the structure of the stirrup is exactly the same as that of the keeper and all the variants applicable to the structure of FIG. 3 are also the same in FIG. 15
  • the only differences lie in the fact, on the one hand, that the heads of the fixing screws 14 (FIG. 3) are not split heads but heads forming knurls 44 to allow their manual actuation and, on the other hand, that the fixing plate is mounted on the door using wood bolts 45 cooperating with cap nuts 46, or simple nuts, or even using machine screws 47 with binding sockets 48.
  • FIG 16 shows an alternative embodiment of the stirrup.
  • the stirrup fixing sole 41 has a triangular projection 42 fixed to the door by screws 43 at points very distant from the locker 37. It follows that the strength of the binding is further improved. It is clear that the female parts used could be replaced by male parts, and vice versa. It is understood that the present invention is not limited to the embodiments described and shown.
  • the fixing means according to the invention can be used to fix an overlay, having substantially the shape of the hubcap 12, on the existing keeper and to fix this keeper by means of machine screws in threaded inserts.
  • Several devices can be joined on a sole of the total height of the door.
  • the invention is also adaptable for mounting on wood, using wood bolts (Japy type) on double-leaf doors or on shutters.
