Description

The invention relates to a mortise cremone for an opening of

  being, door or the like comprising a two-part casing

  lying in a longitudinal plane of the cremone and abutting against each other, said housing having a larded rear portion whose configuration allows a notch in the sill of the opening by frontal drilling; a headrest fixed rigidly on the front of the housing and intended to cover a longitudinal groove made in the

  song of the opening; two locking rods moving in the-

  said groove and located approximately on the tangent to the body of a follower and in extension of one another; a follower, housed in the housing and actuated by an external maneuvering member, whose body

  is provided on its periphery with teeth cooperating directly or indirectly

  with the ends of the locking rods and transforming the rotation of at least a quarter turn of the follower into a simultaneous translation of equal stroke but in opposite directions of each of the two

locking rods.

  Document EP-B 1-0009 457 already discloses a cremone

  as described in the previous paragraph Indicated cooperation

  between the teeth arranged around the body of the follower and

  the end of one of the locking rods is

of a flexible element.

  To be able to involve the rods a given race, the follower must have a pitch diameter developing this race Cedit diameter, increased by the thickness of the flexible element and the thickness of the

  wall of its guide corridor, determines the configuration of the

  rear section of the case and, therefore, the diameter of the hole for

  the notching of the central rear part of the casing.

  guration of the back of the housing is dependent on the curvature

  of the flexible element This curvature can not have an inferior radius

  within a certain minimum radius so that the flexible element does not undergo structural modification by a repetition of inverted folds

  and slides easily into the guideway of the housing.

  However, it is advantageous that the central rear part of the housing fits into a bore whose diameter is closest to

  as close as possible to the outer diameter of the follower.

  The purpose of the present invention is to design a double-action mortise locker that lands in a groove starting from the edge of the opening while allowing the housing housing to be made from the 2-sided opening by means of a single operation of pergage from the inner face of the opening and whose diameter of the central rear portion is identical or approximately identical to the outer diameter of the follower. To this end, the invention relates to a mortise cremone for a window, door or the like comprising a housing in two parts joining in a longitudinal plane of the cremone and bearing against one another, said case having a larded rear part whose configuration allows a notch in the sill of the opening by frontal drilling; a headrest fixed rigidly on the front of the housing and intended to cover a longitudinal groove made in the edge of the opening; two locking rods moving in said groove and located approximately on the tangent to the body of a follower and in extension of one another; a foootlogé in the housing and actuated by an external maneuvering member, whose

  body is provided on its periphery with teeth cooperating directly or indi-

  right with the ends of the locking rods and

  rotation of at least a quarter turn of the follower into a transla-

  simultaneous simultaneous stroke but in opposite directions of each of the two locking rods characterized in that, in comboinaison, the follower has a thickness extending over most of the width of the housing whose walls have a thickness sufficient to serve as bearings to the follower shaft; the ends of the locking rods cooperating directly or indirectly with the follower,

  have a reduced width and intersect; the end of the first

  The first locking rod has teeth which are tangent to the body of the follower meshing directly with a portion of the thickness of the teeth of the follower and the end of the second locking rod comprises

  teeth tangent to the outer circumference of the follower mesh

  the other part of the thickness of the furrow's teeth through the

  intermediate of at least one reversing gear.

  These features make it possible to arrange the indirect cooperation means, consisting of at least one reversing gear, between the follower and the end of the second locking rod, inside the longitudinal groove in which the casing and the rods are placed.

  locking and thereby achieve the purpose that the invention has set.

  To increase the diameter of the reversing gear, the invention provides for the headrest to be offset in a plane parallel, over approximately the length of the casing, by a value less than the rebate clearance of the window, door or the like, and that the end of the second locking rod is offset in a plane parallel to the remote part

of the headrest.

  In addition, according to the invention, a better transmission between the

  follower and the end of the second locking rod is made

  that the length of the toothing of the end of the se-

  conde locking rod is such that the teeth meshes with

  two reversing gears arranged on both sides of the follower.

  According to another embodiment of the invention, the space available

  for the reversing gear and the rods can be increased further

  when the headrest is removed between the mounting locations of the housing on the faceplate and the cleared location is covered

  on both sides by a return of each part of the case.

  The strength of the reversing gear is reinforced by a

  that the shaft and the ring gear of the reversing gear are

one piece.

  The mortise cremone 1 for an opening of window, door or analog

  logue is placed in a longitudinal groove formed in the edge of the opening This cremone larder 1 comprises a housing 2 whose base is placed in said longitudinal groove and the rear part larded in a housing made from the face of the opening and obtained by

  a single drilling operation performed in the inner face of the

  On the front face 3 of the housing 2 is fixed, rigidly, a headrest 4 intended to cover the longitudinal groove made

in the song of the opening.

  The housing 2 is made in two parts 5, 6 joining in a

  longitudinal plane 7 of the mortise cremone 1 These two parts 5, 6

  are mutually parallel to the headrest 4 and have two walls 8, 9 having on their rear edge 10 a larded portion

  11 It has a configuration such that it allows the said operation

  frontal drilling ration practiced in the inner face of the opening.

  Advantageously, this configuration has approximately the shape of a disc cut according to secante secured to the walls 8, 9 and protruding relative to the rear edge 10 Between the inner faces 12, 13

  walls 8, 9 is disposed a follower 14 actuated by a control member

  external work (not shown) The follower 14 consists of a body and a shaft 16 protruding from the two faces 17, 18 of the

  body 15 of the follower 14 The ends 19, 20 of this shaft 16 are lo-

  in bores 21, 22 made in the walls 8, 9 The thickness

  of the latter is such that the walls 8, 9 serve as a support for the

  16 of the follower 14 The thickness 23 of the body 15 of the follower 14 is practically

  identical to the space between the internal faces 12, 13 of the

  8, 9 The diameter of the body 15 of the follower 14 is such that its circumference

  outer edge 24 is substantially flush with the rear edge 25,

  26 of the walls 8, 9 Because the body 15 of the follower 14 is conveniently

  equal to the space between the inner faces 12, 13 of the walls 8, 9 of the housing 2, the follower 14 stiffens the housing 2 and annihilates all

  crushing both walls 8, 9 The follower 14 has on its circumference

  outer circumference 24 of the teeth 27, 28 extending over the entire thickness of the

body 15.

  The cremone larder 1 also comprises two locking rods

  29, 30 located approximately on the tangent to the body 15 of the follower 14 These two locking rods 29, 30 are arranged in the extension of one another and move in opposite directions in the longitudinal groove 5 formed in the opening of the opening Each locking rod 29, 30 has an end 31, 32 of reduced width relative to the normal width of the locking rods

  As a result, these ends 31, 32 can intersect and

  each bear on its upper face 33, 34 a set of teeth 35, 36 co-operating

  either directly or indirectly with the teeth 27, 28 of the

lot 14.

  For this purpose, the end 31 of the first locking rod

  29 has a toothing 35 tangent to the body 15 of the follower 14 As shown in FIG.

  2, 6 and 7, this toothing 35 meshes directly with a portion 37 of the thickness of the teeth 27, 28 of the follower 14.

  locking rod 29 moves through an opening 38

  in the end 39 of the casing 2 and slides on a return 40 solid-

  from one of the parts 6 of the housing 2.

  On the other hand, the end 32 of the second locking rod

  has a toothing 36 tangent to the periphery of the follower 14, that is to say

  say that the toothing 36 is tangent to the outer circumference 24 of the teeth 27, 28 of the follower 14 This toothing 36 cooperates indirectly with the other part 41 of the thickness of the teeth 27, 28 of the follower 14 This

  locking rod 30 moves through an opening 42

  located in the other end 43 of the housing 2 and slides along the rear face 44 of the trestle 4 is inserted between the follower 14 and the

  second locking rod 30 at least one reversing pinion 45 is

  grazing on the one hand with the teeth 27, 28 of the follower 14 and, on the other hand,

  on the other hand, with the toothing 36 of the end 32 of the second rod

  As a result of the presence of this reversing gear 45, the

  conde locking rod 30 moves in the opposite direction relative

  at the first locking rod 29 This reversing gear 45 constitutes

  kills the indirect cooperation means between the follower 14 and the end 32 of the second operating rod 30 according to the invention, this

  means of indirect cooperation is located inside the groove

  of the opening of the opening and in which are lo-

  the housing 2 and the locking rods 29, 30.

  45 comprises a shaft 46 whose ends 47, 48 are engaged

  in bores 49, 50 made in the walls 8, 9 (see Figure 6).

  Advantageously, the shaft 46 and the ring gear 51 of the reversing gear 45 form

  a single room, which reinforces the strength of the

reversing gear 45.

  To obtain a better transmission between the follower 14 and the second locking rod 30, the end 32 of this second locking rod 30 is given a length such that the toothing 36

  can cooperate with two reversing gears 45 and 52.

  45, 52 are identical and arranged on either side of the follower 14. To increase the reliability of the cremone to larder 1, it is interesting

  to increase the diameter of the reversing gears 45, 52.

  According to the first embodiment (see essentially Figures 1 and 2), is given to the headrest 49 on approximately the length of the housing 2, a remote part 53, which increases the available space between the rear face 44 of the cover 4 and the body 15 of the follower 14 The thickness 54 of this portion 539 offset in a plane parallel to the entire headrest 4, has a value lower than the game

  recess of the window, door or the like.

  Similarly, the end 32 of the second locking rod 30 has a remote portion 55 parallel to the remote portion 53 of the
