Definitions

  • the invention relates to a locking fitting, such as a lock, a bolt-lock or the like, comprising a housing integral with a headrest and containing a control mechanism provided with a follower and / or a key element for actuating locking elements and more particularly a latch bolt formed by a body projecting from said headrest and an axis housed in the housing.
  • This invention will find its application more particularly in the field of building hardware.
  • a lock fitting of the lock type has a control mechanism, generally of less complexity, which makes it possible to actuate, in return, only a limited number of locking elements.
  • these locking elements are a latch bolt and a deadbolt.
  • these known locking fittings are designed in a substantially identical manner and include a housing in which the control mechanism is housed, this may include a nut and / or a key element making it possible to act on the locking elements, for example a latch bolt, a deadbolt, one or more rods.
  • control mechanism of a lock or lever-lock also includes auxiliary parts necessary for its proper functioning.
  • elastic return means generally cooperate with the latch bolt to return the latter automatically to the projecting position when the user releases his action on the handle.
  • the latter is able to return to its horizontal rest position under the effect of elastic means acting on the follower.
  • this control mechanism is provided, in certain cases, with intermediate members making it possible to act on the latch bolt under the action of the key element.
  • the part of the body, introduced into the housing, of this latch bolt has several machining operations allowing cooperation with the aforementioned intermediate members. These machining operations very often represent a significant loss of material and costly operations in the manufacture of locking fittings.
  • a lock comprising a housing secured to a headrest and in which is housed a control mechanism making it possible to actuate a latch bolt and a deadbolt.
  • the latch bolt consists of a body projecting from the headrest and an axis extending said body inside the housing. This axis is slidably mounted in a bearing integral with one of the cover plates of the housing.
  • an elastic element engaged on the axis and cooperating, simultaneously, with a stop provided on the latter and with the bearing, makes it possible to maintain the latch bolt in the projecting position.
  • the control of the latch bolt can be carried out either from a key element, or under the action of a follower on which the user can act by means of a handle.
  • said follower comprises a control finger cooperating with a second stop located on the free part of the axis of the latch bolt, being projecting relative to the abovementioned bearing.
  • this axis is provided, in its front part, with a bulge in which a groove is machined allowing the cooperation of an intermediate member, connected to the key element, with the latch bolt.
  • This lock has a number of drawbacks due to the particular configuration of the latch bolt.
  • the cooperation between the intermediate member, in connection with the key element, and the axis of the latch bolt requires, on the one hand, a surplus of material, formed by a bulge at the level of the front part of this axis, allowing the machining of a groove.
  • said intermediate member must be designed while respecting relatively reduced tolerances.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims solves the problem of creating a locking fitting, such as a lock, lever-lock or other, comprising a housing secured to a headrest and containing a control mechanism provided with a follower and / or a key element for actuating locking elements and more particularly a latch bolt formed by a body projecting from said headrest and an axis housed in the housing, said bolt U-turn being provided, on the one hand, control means constituted by a slide mounted free in rotation on the U-bolt and comprising support surfaces on which act, respectively, a control member connected to the key element and a control member integral with the follower and, on the other hand, guide and positioning means formed by a spacer, also mounted on the axis cooperating with the cover plates of the housing, this spacer serving to guide, simultaneously, the latch bolt and the slide inside said housing.
  • the locking fitting 1 shown in FIG. 1 and in accordance with the invention, relates to a lock formed, essentially, of a housing 2 secured to a headrest 3 and containing a control mechanism 4 making it possible to actuate locking elements 5, 6 and, in particular, a latch bolt, marked with the reference 5, and a deadbolt, noted 6.
  • its housing 2 Within the framework of a lock fitting recessed in the front upright of an opening leaf of a door, window or the like, its housing 2 generally consists of two cover plates 7 connected by spacers 71 and attached to the headrest 3 either by riveting, welding or other.
  • the control mechanism 4 of this lock comprises a follower 8 made integral in rotation with an axis 9 and cooperating with the latch bolt 5.
  • the axis 9 has, in its center, a square hole 10 in which is engaged the handle operating square. This allows the user to act on said follower 8.
  • the follower 8 is provided with elastic return means making it possible to return the operating handle to the rest position after closing or opening the door.
  • an elastic element such as a spiral spring, cooperating simultaneously with the follower 8 and a spacer or a lug secured to the one of the cover plates 7 of the housing 2.
  • the control mechanism 4 also comprises a key element 11, such as a barrel or the like, the function of which is to actuate, by means of control members 12, 13, respectively, the half bolt turn 5 and the deadbolt 6.
  • a key element 11 such as a barrel or the like, the function of which is to actuate, by means of control members 12, 13, respectively, the half bolt turn 5 and the deadbolt 6.
  • the U-bolt 5 comprises guide and positioning means 14 cooperating with the housing 2, integrated elastic return means 15 making it possible to automatically return it to the active position, namely salient with respect to the headrest 3, and control means 16 authorizing the interaction with the follower 8 and / or the key element 11.
  • the U-bolt 5 is formed of a body 17 constituting the head of the bolt emerging from the headrest 3 through a slot 18 produced in the latter.
  • This body 17 is integral with a horizontal axis 19 inserted in the housing 2 and provided with guide and positioning means 14.
  • the latter are formed by a spacer 20 disposed perpendicularly to the cover plates 7 of the housing 2 and comprising at its center an orifice 21 serving as a passage for the axis 19 of the U-bolt 5.
  • This spacer 20 is made integral with the cover plates 7 after assembly of the housing 2.
  • said cover plates 7 are provided with a groove in which can be engaged a tongue 22 located on the upper and lower edge of the spacer 20 and ensuring perfect immobility of the latter when the axis 19 slides in the orifice 21.
  • the control means 16 of the U-bolt 5 advantageously consist of a slide 23 mounted to rotate freely on the axis 19.
  • This slide 23 has support planes 24, 25 capable of cooperating with control members 12, 26 which are respectively connected to the key element 11 and integral with the follower 8.
  • This slide 23 has, more particularly, a central light 27 delimited, at the ends, by transverse flanks 28, 29 and serving for the passage of the spacer 20 and to the axis 19 of the U-bolt 5.
  • This axis 19 crosses, right through, the transverse flanks 28, 29 thanks to orifices 30 arranged in the latter.
  • the slide 23 moves relative to the spacer 20.
  • the lateral edges 34 of the latter cooperate with the longitudinal edges 33 of the central light 27 of the slide 23, which allows the latter to be guided inside the housing 2.
  • the support planes 24, 25 of the slide 23 are constituted, respectively, by a wing 35, provided with an abutment plane 36 and integral with one of the longitudinal edges 37 of said slide 23, and by the rear transverse flank 28.
  • the key element 11 By actuating the key element 11, it is possible to act on the latch bolt 5 via the control member 12, the upper end of which cooperates with the latter and, in particular, with the abutment plane 36 of the wing 35 of the slide 23.
  • the support plane 24 considerably facilitates the connection between the latch bolt 5 and the control member 12. It should also be noted that the latter can be designed according to relatively wide tolerances.
  • control member 26 is made up of: preferably by a fork 39 made up of two branches parallel radially extending the body of the follower 8.
  • the withdrawal of the U-bolt 5 in the housing 2 can be limited by any known means, for example, a stop integral with said housing 2 and cooperating with the slide 23 or an appropriate arrangement of the cover plates 7.
  • the latter can include on their edge before 40 a cutout 41 made in line with the latch 5 and whose depth defines the maximum withdrawal of the body 17 from the latter in the housing 2 (this embodiment having been shown in FIG. 1).
  • the maximum projecting position of the U-bolt 5 relative to the headrest 3 is determined, on the one hand, by the length 42 of the central light 27, the position of the spacer 20 in the housing. 2 and the width of the legs of the fork 39.
  • the elastic return means 15 consist, substantially, of a helical spring 45 engaged on the axis 19 and coming to bear, at its ends 46, 47, respectively against the front transverse flank 29 of the slide 23 and against the spacer 20.
  • the U-bolt 5 comes to slide in the housing 2 causing the displacement of the slider 23 relative to the spacer 20, from which results the compression of the helical spring 45.
  • this helical spring 45 is able to push back the front transverse flank 29 of the slide 23 and bring the latch bolt 5 back into its projecting position relative to the headrest 3.
  • control means 16 of the U-bolt 5 the guide and positioning means 14 of the latter in the housing 2 and the elastic return means 15 form a whole dissociated from the rest of the control mechanism 4 and of said housing 2, which considerably facilitates the mounting of such a locking fitting 1 according to the invention.
  • the latter also comprises means 48 making it possible to confer on the latch bolt 5 a rotation of 180 degrees so as to ensure its reversibility and, consequently, the reversibility of the locking fitting 1.
  • the means of rotation 48 are accessible from outside the housing 2 and, more precisely, from the front edge of the opening and from an opening 49 produced in the rear edge 50 of the housing 2 in line with the axis 19 of the latch 5.
  • these means of rotation 48 are constituted by elastic means 51 allowing a projection towards the outside of the body 17 of the latch bolt 5 so as to release said body 17 from the light 18 machined in the headrest 3. In this position , it is possible to confer a 180 degree rotation to the latch 5 due to its axis 19 sliding respectively in the orifices 30 of the transverse flanks 28, 29 of the slide 23 and in the orifice 21 arranged in the spacer 20 .
  • the elastic means 51 are formed, substantially, by a helical spring 52 engaged on the part 53 of the axis 19 which is projecting relative to the rear face 54 of the rear transverse flank 28. This spring 52 cooperates, simultaneously, with this face rear 54 and a washer 55 mounted at the end 56 of the axis 19.
  • the spring 52 comes to compress allowing a horizontal displacement of the latch 5 to project said body 17 outside the lumen 18. After rotation of 180 degrees, the body 17 is inserted again into the latter, under the effect of the elastic return exerted by the spring 52.
  • this latch 5 is facilitated by a groove 57 made in the end 56 of the axis 19 allowing the engagement of a screwdriver.
  • the washer 55 can be formed, more particularly by a circlip or the like cooperating with a peripheral groove machined in the axis 19 at its end 56.
  • the slider 23 can fulfill the function of guiding the latch bolt 5 and, in particular, of the body 17 during their rotation, to facilitate, again, the engagement of the latter in the lumen 18 of the headrest 3 .
  • the dimensions of the front transverse flank 29 of the slide 23 are substantially greater than those of the slot 18. Therefore, during the compression of the spring 52, the transverse flank 29 cooperates with the headrest 3, giving rise to significant friction forces between them. This avoids an offset of the body 17 with respect to said lumen 18 during the rotation of the U-bolt 5.
  • the dimensions of said front transverse flank 29 of the slide 23 are substantially smaller than those of the slot 18.
  • the compression of the spring 52 not only causes the projection of the body 17 outside the slot 18, but also engaging the front transverse flank 29 in the latter. This results in the cooperation between the side edges 60 and bottom and top 61 of the front transverse flank 29 with the longitudinal and transverse edges of the lumen 18, guiding the latch bolt 5.
