Definitions

  • the invention relates to a cremone bolt with two-way headrest comprising, in a housing integral with the headrest, a mechanism comprising a nut directly controlling the end of a first locking rod, sliding along the internal face of the headrest by means of a connecting piece provided with a stud cooperating with a light produced in the body of the follower and indirectly, the end of a second locking rod, disposed against the bottom of the housing, by the through a reversing element, the two locking rods moving in opposite directions being arranged in the same alignment and flat against the internal face of the headrest.
  • a cut is made in the edge profile of the opening of a window, French window or the like, the depth of which depends on the width of the housing, said width being determined by the distance from the axis of the follower from the external face of the headrest.
  • this distance is variable, it is necessary to also vary the depth of the notch for the housing of the housing.
  • These variations in the depth of the housing oblige the manufacturer of windows, French windows or the like, on the one hand, to adjust his notching machine to the depth of the housing necessary for the housing, and, on the other hand, to provide a more profiled profile. wide to avoid weakening of the amount of the window sash, French window or the like by deep notching.
  • cremone bolt has been designed to standardize the depth of the notching of the housing for the housing, this depth being the same despite different distances between the axis of the follower and the external face of the headrest.
  • a cremone bolt with a double-headed headrest comprising in a housing integral with the headrest , a mechanism comprising a follower directly controlling the end of a first locking rod, sliding along the internal face of the headrest by means of a connecting piece provided with a stud cooperating with a light produced in the body of the follower and the end of a second locking rod, disposed against the bottom of the housing, by means of an inverting element, the two locking rods moving in opposite directions being arranged in the same alignment and flat against the inner face of the headrest.
  • this cremone bolt has several drawbacks. Indeed, the connecting piece includes a guide edge bearing against the shaft of the follower. Because this shaft has a small diameter to reduce the size of the mechanism housed in the housing, the wear of said shaft, following repeated friction by the guide song of the connecting piece, is accelerated, which reduces reliability cremone bolt.
  • the end of the second locking rod comprises, facing the follower, a release light. It is certain that the latter weakens said end of the second locking rod, especially that the width of this clearance light must be wider than the thickness of the nut to prevent the latter from getting stuck in the clearance light.
  • the double direction headrest lever comprises in a housing integral with the headrest, a mechanism comprising a nut directly controlling the end of a first locking rod, sliding along the internal face of the headrest by means of a connecting piece provided with a stud cooperating with a light produced in the body of the follower and, indirectly, the end of a second locking rod, disposed against the bottom of the housing by means of an reversing element, the two locking rods moving in opposite directions being arranged in the same alignment and flat against the internal face of the headrest and whose follower comprises a shaft provided with a concentric reinforcement bearing on the guide song of the part of connection and the internal face of the end of the second locking rod.
  • the concentric reinforcement is a wear ring threaded on the shaft and integral in rotation with the latter.
  • One of the advantages obtained thanks to this invention consists essentially in a good balance of mass conferred on the follower and a symmetrical distribution of the forces generated when locking or unlocking the two rods of the lever.
  • the end of the second locking rod has on its internal face a recess the length of which is at least equal to the sum of the length of the heel of the body of the follower and the length of travel of the second locking rod.
  • the end of the second locking rod comprises a stamped section having a shoulder projecting with respect to the external face of the end of the second locking rod and directed towards the bottom of the housing, the length of this shoulder being at least equal to the sum of the length of the heel of the body of the follower and the length of the stroke of the second locking rod.
  • the bottom of the housing includes a slot in which slides the shoulder of the stamped section from the end of the second locking rod.
  • Figure 1 shows, in elevation and in section, the cremone bolt with double direction in accordance with the invention, the cremone bolt being in the unlocked position.
  • the cremone bolt 1 comprises a housing 2 housed in a notch formed in a groove made in the edge of the upright of a window opening, French windows and the like. This groove is closed by a headrest 3 of a double direction lever and secured to said housing. Along the internal face 4 of the headrest 3 slide two locking rods 5, 6 moving in opposite directions and the ends 7, 8 of which penetrate into the housing 2. These two locking rods 5, 6 are actuated by a follower 9 comprising a body 10 having, when the cremone bolt is in the locked position, a projecting part 11 passing through a lumen 12 produced in the headrest 3 and constituting a beating bolt, a shaft 13, in which a square hole 14 is made for the introduction of the operating square of a handle, and a heel 15.
  • the follower 9 directly controls the end 7 of the first locking rod 5 by means of a connecting piece 16.
  • This connecting piece 16 has a sliding guide edge around the periphery of the shaft 13 of the follower 9 thus ensuring the guiding of this connecting piece 16 and its cooperation with the end 7 of the first locking rod 5.
  • the connecting piece 16 comprises at one of its ends 17 a stud 18 cooperating with a light 19 produced in the body 10 of the follower 9 and at the other end 20 a control stud 21 engaging in an orifice 22 formed in the end 7 of the first locking rod 5.
  • the latter has a toothing 23 driving an reversing element 24 constituted by a toothed pinion which can pivot about an axis 25 integral with the side walls 26 of the housing 2.
  • This reversing element 24 cooperates with a toothing 27 of the end 8 of the second locking rod 6, this end 8 being connected to the second locking rod 6 by a return piece 28.
  • the two locking rods 5, 6 are arranged in the same alignment while the end 7 of the first locking rod 5 moves along the internal face 4 of the headrest 3 and the end 8 of the second rod lock 6 moves along the internal face 29 of the bottom 30 of the housing 2.
  • the shaft 13 of the follower 9 is provided with a concentric reinforcement 31.
  • the concentric reinforcement 31 is an integral part of the shaft 13.
  • the outer periphery 32 of the concentric reinforcement 31 is flush with the edge 33 of the heel 15 and also bears on the internal face of the end 8 of the second locking rod 6.
  • the concentric reinforcement is a wear ring threaded on the shaft 13 and it is integral in rotation with the latter, the outer periphery of this ring being flush with the edge 33 of the heel 15 and takes also pressing on the internal face of the end 8 of the second locking rod 6.
  • the length 36 of this recess 35 is at least equal to the sum of the length 37 of the heel 15 of the follower 9 and the stroke 38 of the second locking rod 6.
  • the excess thickness of the shaft 13 of the follower 9 is at the expense of the thickness of the end 8 of the second locking rod 6. This is why a second embodiment is recommended.
  • the end 8 of the second locking rod 6 comprises a stamped section 39 directed towards the bottom 30 of the housing 2.
  • said end 8 comprises, at the height of the stamped section 39 , a shoulder 40 projecting from the outer face 41 of the end 8 of the second locking rod 6.
  • the length of this stamped section is equal to the length of the shoulder 40.
  • a light 42 whose length 43 is at least equal to the sum of the length of the shoulder 40 of the stamped section 39 and the stroke 38 of the second locking rod 6.
  • the height 44 of the shoulder 40 is equal to or slightly less than the thickness 45 of the bottom 30 of the housing 2, so that the external face 46 of the shoulder 40 is flush or slightly below the external face 47 from the bottom 30 of the housing 2.
  • the stamping depth 48 is equal to the height 44, therefore approximately to the thickness 45.
  • the end is also guided 8 of the second locking rod 6 as a result of the cooperation of the shaft 13 with the bottom of the stamped section 39 via the concentric reinforcement 31 or the wear ring.
