Definitions

  • the invention relates to a locking fitting for a door, window or the like, of the cremone bolt or locking bolt type, comprising a control mechanism provided with at least one wheel toothed engagement with a defined rack, either by a series openings interspersed with rungs, either by toothing, and associated, directly or through a body of appropriate transmission, at least one operating rod for bring it to the locked or unlocked position under the action of a button or a control handle and / or a key element, provided capable of acting, directly or indirectly, on said gear.
  • the present invention will find its application in the field of the building hardware and concerns, more especially the locking fittings of the lever type or lock-bolt.
  • cremones or cremones-locks are distinguished in that they comprise at least one operating rod extending above and / or below a box closing the control mechanism capable of bringing these operating rods in a locked position and unlocking.
  • these operating rods are fitted or act on locking devices which are able to cooperate with strikes.
  • locks and bolts are also known which, through a key element, usually allow to act on a deadbolt so that after unlocking the maneuvering rods an individual, seeking to enter by breaking into a home, must, furthermore, to fracture the key element to obtain complete unlocking of opening.
  • a point opening single locking is often more fragile to such attempted break-in compared to a point opening multiple locks.
  • cremone bolt the control mechanism of which, housed in a housing, includes a follower with a set of teeth capable of coming to mesh on a rack of a transmission member intended to be attached to an operating rod extending on one side of said housing.
  • This cremone bolt also has a reverse gear on which the transmission member still meshes above and another, diametrically opposite and provided capable of cooperating with an extending operating rod and moving in a direction opposite to the previous one.
  • the toothing of the follower is thus defined so that, in position only one last tooth remains partially engaged in the corresponding opening of the rack, the vertex of this tooth forming a stop against which is even come to support a rung of this rack of the transmission organ, in the event that an attempt is made unlocking by direct action on a rod maneuver.
  • the inventive step of the present invention consisted in developing a drive mechanism for lever or lever bolt which is irreversible without this resulted in any increase in the resistance to maneuver provided by the ordered. Indeed, it was necessary to avoid that the resistance felt by the user at the level of a handle or a button order, is more important than usual.
  • the present invention has been able to respond to the problem described above, while respecting the requirements to which it has just been referred to.
  • the invention relates to a locking fitting for door, window or the like, of the cremone bolt or cremone bolt type, comprising a control mechanism provided with at least a toothed wheel engaged with a defined rack, either by a series of openings interspersed with steps, either by a toothing, and associated, directly or through a suitable transmission member, at least one rod of operation to bring the latter into the locking position or unlocked by a button or a handle control and / or a key element, provided capable of acting, directly or indirectly, on said gear, the spacing of the rungs or of the teeth of said rack being determined to allow an idle stroke of the latter in relation to the tooth or teeth of the toothed wheel and on which it comes to mesh, so to make the control mechanism irreversible, the top of these teeth of said toothed wheel being provided capable of defining a bearing surface against which is able to abut, through said empty run, a rung or even a tooth of the rack, following a push from the operating rod on said control mechanism.
  • the present invention has known go against a usual approach in the context of design of locking fittings. More specifically, until now we have constantly sought a decrease in functional games so as to obtain a certain precision in the amplitudes of movement of the moving elements.
  • the present invention allows the design of bolts or bolts that can be described as security for a cost strictly identical to a bolt or conventional bolt lock, having no means of immobilizing in translation their operating rod, once the latter in the locked position.
  • the present invention relates to the field of fittings of lock for door, window or the like, more particularly that of cremone bolts or bolts.
  • cremone bolt 1 comprising two operating rods 4, 5 extending, respectively, above and below a central box 3 and to which the control mechanism 2 of this cremone bolt 1 is able to communicate movements in opposition.
  • gear lever 2 or gear lock 1 is provided with minus a toothed wheel 6 engaged with a rack 7 which can be directly associated with an operating rod 4 knowing that this rack could also equip a suitable intermediate transmission device, moreover connected to this operating rod 4.
  • such a rack 7 can be defined, either by a toothing, either by a series of openings 8, interspersed steps 9, arranged at the level of this operating rod 4 or any other intermediate transmission member.
  • the toothed wheel 6 is none other, here, that the follower on which is able to act the user with a handle or a control button. Also, this toothed wheel 6 or follower has, in its center, a housing 10 for receiving the square of operation of such a handle or control button.
  • the cremone bolt 1 comprises, in this case, a second gear which is in fact a reversing pinion 11 suitable to retransmit the movement communicated to the rod of maneuver 4 to the second operating rod 5 by conferring on the latter a displacement in a direction opposite to the previous. Also, these operating rods 4, 5 come mesh with racks 12, 13 and so diametrically opposite on this reversing pinion 11.
  • the spacing 14, as the case may be, between the rungs 9 or the teeth defining the rack 7 cooperating with the gear 6, is determined to authorize a stroke vacuum 15 of this rack 7 of the operating rod 4 relative to the tooth or teeth 16 of this toothed wheel 6, on which one or which it comes to mesh.
  • the vertex 17 of these teeth 16 corresponding to said toothed wheel 6 is provided capable of defining a bearing surface 18 against which is able to come into abutment, following a displacement of said rack 7 over a length corresponding to the idle stroke 15, a step 9 or a tooth of this rack 7.
  • this displacement of the latter is comparable to a push which one comes to exert from a rod of operation 4, 5 on said control mechanism 2 in a unlocking direction, this during an attempt breaking the door or window fitted with this lever or lock-bolt 1.
  • the present invention should be considered as representing a clear progress in this field of fittings of lock for door, window or the like.
