Definitions

  • the invention relates to a latch for sliding doors, comprising a hook bolt, articulated on the latch housing and controlled by a control element connecting it to an operating handle, an elastic element, indirectly recalling the hook bolt in its position. closing, means for retaining the hook bolt in the closed position and a pusher acting on the latter when the sliding leaf is closed to allow the hook bolt to be returned to the closed position by the elastic element.
  • Such a latch is already known from document EP-A-0 142 342.
  • This latch comprises a blocking device operated by a key.
  • a hook bolt is actuated, pivoting about a hinge pin secured to the housing, by means of a set of parts composed of a connecting rod connected to one of its ends by an axis of articulation with the hook bolt and at the other end by an axis of articulation at one of the angles of a tilting element having approximately the shape of an equilateral triangle.
  • This tilting element pivoting about an articulation axis integral with the housing and located at another angle of this equilateral triangle, is connected by an articulation axis located on the third angle of this equilateral triangle, at the end d 'a lever arm whose other end has a light in which can slide the axis of the operating key.
  • On said axis is mounted a cam cooperating with a retaining means for holding the hook bolt in the closed position.
  • This retaining means is an additional part formed by a rocking lever pivoting about an axis secured to the housing.
  • This tilting lever placed in the retaining position by an elastic element comprises a stop against which the upper edge of the lever arm bears.
  • the object of the present invention is to produce a latch of the above type in which the locking of the hook bolt in its closed position does not require a locking device operated by a key.
  • the invention as characterized in claim 1, makes it possible to achieve this object by providing a latch for sliding doors comprising a hook bolt articulated on the latch housing and controlled by a control element connecting it to a operating handle, an elastic element indirectly recalling the hook bolt in its closed position, means for retaining the hook bolt in the closed position and a pusher acting on the latter when the sliding leaf is closed to allow the return of the hook bolt in the closed position by the elastic element whose control element, acting on the hook bolt, is slidably housed in the housing and comprises a means of retaining means integral with the control element cooperating with the other means of the retaining means integral with the hook bolt in the closed position and that a connection between the control element and the hook bolt comprises a stroke to v ide of dissolution of the cooperation between the retaining means of the control element and the retaining means of the hook bolt in the closed position
  • these means used allow the means for retaining the hook bolt in the open position to be secured to the control element.
  • the pusher acting on the retaining means slides in the housing transversely with respect to the control element and cooperates in each of its extreme positions with an abutment plane and that the distance between the abutment planes is equal to the stroke of the handle.
  • these linings can be linings comprising a safety block thus transforming the entire latch into a sliding door lock as soon as the elastic element is a double reverse inverted device recalling the control element, from the middle of the race, either in the open position or in the closed position.
  • the deviations from the nominal projection dimension of the pusher originating from a more or less precise fitting of the loguet in the opening element are easily compensated by adjustment means providing that the housing is fixed in the opening element by screws. and reverse.
  • the adjustment means can advantageously provide that the latch fixing comprises at one end an axis allowing a slight oscillation controlled at the other end by screws and counter screws.
  • Figure 1 shows, in partial view in elevation and in section, a window or door with sliding doors having a latch according to the invention.
  • Figure 2 shows, in sectional view, the only latch along the cutting line Il - Il of Figure 1. We refer to the two figures.
  • a latch 4 which comprises a housing 5 composed of two housing halves each comprising a transverse wall 8, 9 and two walls 6, 7 parallel to the walls 1, 2 of the sliding leaf 3.
  • the housing 5 comprises a hook bolt 10 which can pivot about an axis 11 integral with said housing 5.
  • the walls 6, 7 of the two housing halves of the housing 5 have a light 12 facing a light 13 made in the internal wall 2 of the sliding leaf 3.
  • These slots 12, 13 allow the passage of the hook bolt 10, the hook 14 of which, in the closed position of the latch 4, projects relative to the external face 15 of the wall internal 2 of the sliding leaf 3.
  • This hook 14 cooperates with a counter-hook 16 of a keeper 17 secured to the frame 18 of the window or door.
  • This keeper 17 consists of an internal element 19 applied against the internal face 20 of the frame 18 and an external element 21 applied against the external face 22 of said frame 18.
  • the internal element 19 has on its face 23 directed towards the external element 21 a boss 24 passing through a lumen 25 formed in the wall 26 of the frame 18. These two elements 19 and 21 are held together by fastening elements 27, 28 also passing through the lumen 25. Because the boss 24 and the fastening elements 27, 28 pass through the lumen 25, it is possible to position the keeper 17 relative to said lumen 25 as a function of the position of the hook bolt 10.
  • control element 29 is actuated by a control element 29.
  • this control element 29 slides inside the housing 5 according to a movement parallel to the walls 1, 2 of the sliding leaf 3.
  • This control element 29 comprises approximately a "U" section, plan view, the opening of which is situated on the side of the internal wall 2 of the sliding leaf 3.
  • the internal faces 30, 31, 32, 33 of the walls 6, 7 , 8, 9, of the housing 5 serve as a guide for the control element 29.
  • the latter connects the hook bolt 10 to an operating handle 34 represented in FIG. 1 by its connection axis 35.
  • This connection axis 35 crosses lights 36, 37, formed in the two parallel wings 38, 39 of the control element 29 and lights 40, 41 produced in the transverse walls 8, 9 of the housing 5.
  • the longitudinal axis 42 of the lights 36, 37 is perpendicular to the sliding of the control element 29 while the longitudinal axis of the lights 40, 41 is parallel to this sliding.
  • the hook bolt 10 is connected to the control element 29 by a link 43 comprising an idle stroke 44.
  • This link 43 is composed by a transverse axis 45 secured to the hook bolt 10 and two slots 46, 47 also produced in the two parallel wings 38, 39 of the control element 29, said hook bolt 10 being arranged between the two parallel wings 38, 39.
  • the return of the hook bolt 10 in the closed position as shown in FIG. 1 is ensured by an elastic element 48.
  • This elastic element 48 is interposed between a stop 49 secured to the control element 29 and a stop 50 secured to the housing 5.
  • Each stop 49, 50 comprises a guide 51, 52 on which is threaded one of the ends 53, 54 of the elastic element 48.
  • these retaining means 55 comprise, on the one hand, a notch 56 produced in the hook bolt 10 and, on the other hand, a stop 57 secured to the control element 29.
  • the action edge 58 of the notch 56 of the hook bolt 10 bears against the retaining edge 59 of the stop 57 of the control element 29. It is therefore impossible to cause the tilting of the hook bolt 10 in view of its erasure releasing the sliding leaf 3.
  • the depth of engagement of the stop 57 in the notch 56 is slightly less than the idle stroke 44 of the connection 43 between the hook bolt 10 and the element 29.
  • these retaining means 55 consist of a stud projecting from the underside of the stop 57 cooperating with a housing produced in the hook bolt 10.
  • these retaining means 55 may consist of a control finger located at the upper part of the hook bolt 10 and of a housing provided in the stop 57.
  • the penetration of the pin or the control finger, respectively, in the housing of the hook bolt 10 or in the housing of the stop 57 is slightly less than the no-load stroke 44 of the connection 43 between the hook bolt 10 and the control element 29.
  • the operating handle 34 is actuated, causing the sliding element of the control element 29 to start to slide.
  • This sliding start causes the cooperation between the catch 56 and the stop 57 to dissolve.
  • the hook bolt 10 is not driven towards its open position because the link 43, in particular the axis 45 moves in the slots 46, 47. This is not that when the song lower 60, 61 of the lights 46, 47 comes into contact with the axis 45 that the hook bolt 10 is actuated by the control element 29.
  • the latch 4 comprises a pusher 62.
  • the latter passes through a lumen 63 formed in the walls 7 of the housing 5 and the lumen 13 of the internal wall 2 of the sliding leaf 3.
  • the pusher 62 slides transversely relative to the control element 29 and it is resiliently returned to the projecting position by an elastic element 64 interposed between the bottom 65 of a bore 66 formed in the rear face 67 of the pusher 62 and the internal face 30 of the wall 6 of the housing 5 .
  • the rear face 67 is provided with a transverse slide 68, the ends 69, 70 of which move in slots 71, 72 made in the transverse walls 8, 9 of the housing 5.
  • the control element 29 of the lights 73, 74 In the parallel wings 38, 39, the control element 29 of the lights 73, 74.

  • One of the abutment planes 75 is constituted by the upper edge of the vertical wing of the light in the form of a square 73, 74 while the other abutment plane 76 is formed by the upper edge of the horizontal wing of the square light 73, 74.
  • the spacing 77 between the abutment planes 75, 76 is equal to the stroke of the operating handle 34 and, consequently, to the stroke of the control element 29.
  • the operating handle 34 is actuated, causing the start of sliding of the control element 29, causing the cooperation of the stop 57 and the notch 56 to dissolve. While continuing to operate the operating handle 34, the lower edge 60 , 61 of the lights 46, 47 drives the axis 45 causing the rotation of the hook bolt 10 about the axis 11 and, therefore, the opening of the latch 4.
  • the elastic element 48 is compressed.
  • the square-shaped slots 73, 74 slide along the transverse slide 68 of the pusher 62 until the lower edge of said slots 73, 74 abuts against the lower edge of the transverse slide 68.
  • the elastic element 64 relaxes by pushing the puussoir 62 outwards.
  • the abutment plane 76 prevents the return of the control element 29 under the thrust of the elastic element 48.
  • the keeper 17 pushes the pusher 62 by compressing the elastic element 64 so that the transverse slide 68 comes to be placed in the vertical wing of the square-shaped lights 73, 74 releasing the action of the elastic element 48.
  • the latter relaxes and pushes back the control element 29 until the abutment plane 75 bears against the upper edge of the transverse slide 68.
  • the action of the lights 46, 47 on the axis 45 causes the notch 56 to cooperate with the stop 57 while the sliding of the control element 29 in the housing 5 causes the operating handle 34 to return.
  • the latch 4 can be fitted with fittings for windows or sliding doors with sliding handles. If necessary, these fittings can be fittings comprising a block that transforms the safety latch into a sliding door lock.
  • a double inverted return device 78 is provided, recalling the control element 29, from mid-stroke, either in the open position or in the closed position.
  • This inverted double return device 78 comprises an elastic element 79, the two ends 80, 81 of which are threaded on axes 82, 83 of two rockers 84, 85.
  • the head 86 of rocker 85 can pivot in a housing 87 produced in the transverse wall 88 of the control element 29 while the head 89 of the rocker 84 can pivot in a housing 90 formed in the walls 7 of the housing 5.
