Description

ROTATING HANDLE WITH KEY LOCK

  The present invention relates to a rotary handle

  key lock for active rod fitting or control rod with three control positions, for example a closing position, a tilting position and a pivoting position,

  in the case of which it is provided, in the lever or joystick

  actuation, eccentrically to the mounting and support axis of this lever or actuation handle, a locking rod

  which, through the cylindrical core of an iron cylinder

  can be actuated using a key, can be adjusted in the axial direction so as to take different depth positions relative to corresponding recesses which are provided offset by 1800 relative to each other around the mounting and support axis of the rotary handle, in the round escutcheon or rosette on which the rotary handle is mounted and which

  is fixed by screwing to the sash of a window or to the sash of a door

  te, and / or in a cover or closure plate that covers

  the fixing screws of this round escutcheon or rosette.

  There are already revolving handles with key lock

  that are constructed in many forms of achievement

  We will cite here, in this respect, only simple

  As examples, rotary handles like this that are con-

  naked by German publications DE-OS 25 42 326, DE-AS

26 10 975 and DE-OS 29 10 295.

  All key-operated rotary handles constructed according to the embodiments which are known up to now are provided, for actuation of the locking rod, with locking cylinders specially designed for this purpose, which are, according to the publication DEOS 25 42 326, in the form of cylinders

  oval, according to publication DE-AS Z 6 10 975, in the form of cy-

  round linders and, according to publication DE-OS 29 10 295, in the form

me of profiled cylinders.

  It is often necessary to incorporate the revolving handles

  lockable for fittings with active rods or rods

  -2- control of windows, doors or other elements of the same kind, in relation to the actuation by key, to closing devices such as those which are currently in use in

  many buildings The closing cylinders, for such devices

  positive closure, are supplied by different manufacturers and are therefore also provided with multiple different closure systems.

  Since most of the locking devices

  installed and in use work with profiled cylinders, it is

  necessary that one can have a rotating handle

  lock type of the type in question in this presentation which lends itself to be incorporated without difficulty in the aforementioned closing devices, without the manufacturer of the closing device having to

  this effect provides a specially designed profile cylinder.

  The problem which has just been stated is solved by the pre-

  invention, according to an embodiment characteristic of the revolving handle with key lock which is the subject thereof, by the fact

  that the closing cylinder is in the form of a half

  profiled cylinder, of the kind widely used on the market, which comprises a bit which can be rotated by means of the core

  of the cylinder, and in that the locking rod is provided, at the end

  tee which engages in the handle, a substantially U-shaped stirrup which surrounds the narrow body part of the profiled half-cylinder, stirrup which, at each of its two branches, has a control face which follows a direction inclined in the longitudinal direction and which is in the area of movement of the bit, the two control faces in directions inclined in opposite directions

  relative to each other and further being offset from each other

  port to side in the longitudinal direction to an extent which corresponds

  lays the value of the width of the bit.

  Since the profiled half-cylinders fitted with a purlin-

  tone that can be rotated through the soul of the cy-

  lindre which are currently widespread in the trade are, as regards their dimensions of cross section and length, designed according to the standards, one profits, according to the present invention, -3- from the advantage which resides in that the handle rotary key lock can easily be fitted with locking cylinders of different manufactures and can therefore, without difficulty

  either even at any time after installation be incorporated

  to any closing device. According to another characteristic of embodiment of the revolving handle with lock which is the subject of the present invention, the two aforementioned control faces are formed by edges in inclined directions of window cutouts which are

  provided in the stirrup branches.

  Another possible characteristic of the revolving handle with key lock which is the subject of the present invention resides in that the stirrup of the locking rod surrounds in a U-shape, from the bottom, the narrow body part of the profiled half-cylinder and in that the locking rod is supported on a transverse wall

  formed at one end of the stirrup.

  According to yet another characteristic of embodiment of the revolving handle with key lock which is the subject of the present invention, the stirrup of the locking rod can however also surround

  U-shaped, from the posterior end, the narrow body part

  of the profiled half-cylinder, in which case the locking rod takes on

then on the soul of the stirrup.

  It is also possible, according to the present invention, to produce the handle

  turning lockable subject to it in a form

  me of relatively narrow construction and thinned if, according to a

  Another feature of this handle is the ro-

  the bit inside the twist handle is limited

  by stops, at an angle of 90 maximum Under the effect of a ro-

  tation of the bit 45 in one direction from its basic position, the locking rod can, via the stirrup, which has the inclined control faces, be placed in the locking position and, from this way, hold the twist grip against

  any unwanted rotation relative to the round escutcheon or rosette.

  Under the effect of a subsequent rotation of the bit 45 in the opposite direction from the basic position, the blocking rod can on the other hand be released again by the intervention of the control faces which its stirrup A removal of the key from the soul

  of the cylinder is only possible if the bit is in the posi-

  Therefore, for the removal of the key, after engagement or after disengagement of the locking rod, the bit must always be brought back to the basic position by rotating it. invention, according to another characteristic of the revolving handle which is the subject of this, it is provided that the two positions that the locking rod can assume by sliding or sliding in the axial direction can be fixed by at least one stop device mounted in the revolving handle, which stop device is advantageously

  assistant to the stirrup of the locking rod to cooperate with it.

  The fixing of the profiled half-cylinder in the recess of the rotary handle which is intended to contain it may or may be

  carried out in the conventional and current manner for pro cylinders

  spun, by transverse screwing, using a screw cooperating with a tapped hole formed in the narrow body part of the profiled half-cylinder, or else, for the same purpose, special fastenings may however be provided. tightening or stopping between the

  profiled half-cylinder and the revolving handle.

  The problem posed can still be solved by the present invention, according to another characteristic of embodiment of 'the

  revolving handle which is the subject of this, by the fact that the cy-

  closing liner is in the form of a half-cylinder

  commercially available gender profile, which has a breakdown

  tone that can be rotated through the soul of the cy-

  lindre and by the fact that the blocking rod is provided, at the end which engages in the lever or actuating lever, with a substantially U-shaped caliper which surrounds the narrow body part of the profiled half-cylinder , stirrup which, at each of its two branches, has a control face which follows an oblique direction

  in the longitudinal direction and which is in the displacement zone

  ment of the bit, the two control faces being provided in the same obliquity position, but having obliquities of direction - opposite one with respect to the other, and being, by their ends turned one towards the other, provided offset in relation to each other in the longitudinal direction to an extent which corresponds to

  measuring the displacement travel of the locking rod.

  According to yet another characteristic of embodiment of the revolving handle with key lock which is the subject of the present invention, it is further provided that the stirrup of the locking rod surrounds in a U-shape, from the rear end , the narrow body part of the profiled half-cylinder and the stirrup arms are guided exclusively laterally, next to this part of

  narrow body of the profiled half-cylinder.

  A particularly important construction feature

  of the revolving handle with lock which is the subject of there pre-

  sente invention resides, according to another characteristic thereof,

  in that each of the legs of the stirrup and the corresponding guide

  dant provided in the lever or actuator have a

  shape of semi-circular, triangular or prismatic cross-section

  tick in trapeze and in that the control faces are

  always in this one on a track which is adapted to the circle of rota-

  tion of the bit, but following an oblique direction to the side.

  Finally, according to another characteristic of embodiment of the revolving handle with key lock which is the subject of the present

  invention, it has proven to be advantageous for the control faces to follow

  each wind / a helical line wound around the axis of rotation of the bit, the generatrices of the helical lines being formed by

  the end edges of the bit.

  Other features and advantages of the round handle

  lockable nante which is the subject of the present invention se-

  will be further explained below, in great detail, with the aid of examples of embodiment of this handle which are illustrated by

drawings annexed to this memoir.

  In these drawings, FIG. 1 is a view, on a considerably enlarged scale

  -and partly in longitudinal section, of a rotating handle to close-

  key ture as it occurs when the locking rod -6 is in the locking position; FIG. Z is a view, corresponding to that of FIG. 1, of the rotary handle with key lock, which however represents this handle as it appears when the blocking rod is in the disengaging or unlocking position; Figure 3 is a sectional view along line III-III of

  and partly in longitudinal section, of a revolving handle to close-

  key ture as it occurs when the locking rod is in the locking position; Figure 6 is a view of a portion of the rotating handle visible in Figure 5, which however shows the locking rod in the release or unlocking position; Figure 7 is a sectional view along line VII-VII of

  FIG. 5, of the revolving handle with key lock which represents

  of FIG. 5, of the revolving handle with key lock which

  shows this figure, and Figure 9 is a cross-sectional view, corresponding to that of Figure 7, of a rotary handle with key lock corresponding to an embodiment which has a slight variant

compared to the previous one.

  The turnable handle can be locked which is shown

  shown in Figures 1 to 4 of the accompanying drawings includes a, é-

  round cusson or rosette 1, which is for example mounted on the front face, local side, of a window casement or a door leaf and which can be fixed by screwing to this casement or this leaf or to

  an active rod or control rod fitting mechanism boftier

  7 - from which is mounted in the leaf or in the leaf The round escutcheon or rosette I is for this purpose pierced with passage holes 2 intended for the installation of the fixing screws, the heads of which are frustoconical, which will be after fixing in the form of submerged heads, are placed in shaped flared recesses

  of truncated cone 3 which are formed in a counter plate

  metal port 4, which was placed from above in the round escutcheon or rosette 1 So that the submerged heads of the two fixing screws

  are invisible and not accessible, the counter plate

  support 4 is covered with a cover or closure plate which, in a manner known per se, can be moved so as to

  go from the closed position, in which it is shown

  felt in the drawing, to a release position, and vice versa.

  The actuating lever or handle 7 is mounted, by its

  neck 8, so as to be able to turn, in a sleeve 6, come from mqu-

  Lage with the round escutcheon or rosette 1, sleeve which crosses both the

  backing plate 4 as the cover or closing plate

  ture 5 Concentrically to the axis of rotation of the lever or actuating handle 7, in the neck 8 thereof, is mounted the rod of square cross section 9 which, conventionally and commonly, engages in the nut , also square cross section, of an actuation mechanism of the fitting with active rod or control rod The rod of square cross section 9 can in this case be mounted so as to be able to be detached, but not to be able to turn , in the neck 8 of the lever or actuation handle

  7 It can however also be formed directly in this-

  it and it can, moreover, be anchored there, without possibility of rotation

  relative tion, by means of a collar of relative cross section-

  ment large 10, in polygonal form or alternatively

  both knurling at the periphery.

  In the lever or actuating handle 7 is formed, in

  a direction parallel to that of the neck 8 and the cross section rod

  dirty square 9, from the front or anterior thereof,

  a recess 11 whose profile has a shape which corresponds in sub-

  stance to that of the cross section of a profiled half-cylinder -812, of common type commercially, profiled half-cylinder which is represented by a dashed line in FIG. 1 and in FIG. 2 of the drawings below. annexed Part 11 ', dimensions

  relatively large and substantially circular in shape, obviously

  It is provided along the same axis as the neck 8 and, therefore, along the same axis as the cross-section rod

  square 9 of the lever or actuating handle 7, while the

  tie 11 ", of smaller width, but elongated, of the recess it follows a direction substantially parallel to the longitudinal direction of the spout

  grip 13 of the lever or actuating handle 7.

  In the case of the embodiment of a turn handle-

  key lock which is illustrated by Figures 1 to 3 of the accompanying drawings, it is still formed in the lever or actuating handle 7, from the rear face thereof, which

  faces the round escutcheon or rosette 1, a recess 14 pre-

  sensing a substantially U-shaped cross section, which is closed by a bottom plate 15, which, on the one hand, can be fixed by matting to the lever or actuating handle 7 and, on the other hand, surrounds the neck 8 of this lever or lever and, in this place, additionally bears on the sleeve 6 of the round badge

or rosette 1.

  In the abovementioned recess 14 is guided, so as to be able to move therein in the longitudinal direction, a stirrup 16, substantially U-shaped which surrounds, from the bottom, the narrow body part of the profiled half-cylinder 12, as can be seen particularly clearly with reference to FIG. 3 of the drawings appended to a transverse wall 17 of the stirrup 16 substantially in the shape of a U is rigidly fixed a locking rod 18, which passes through a hole 19

  formed in the bottom plate 15 and which, in the release position-

  by sliding or sliding in the axial direction, position in which it is shown in Figure 1, can engage

  by adapting shapes in 20 'and 20 "stop holes that pre-

  feel the cover or closure plate 5 and / or in holes

  stop 21 'and 21 "presented by the counter-support plate 4

  that the locking rod 18 is in the release position

  that it took by sliding or sliding, position in the-

  as it is shown in Figure 1, the lever or actuating handle 7 is therefore blocked, relative to the round escutcheon or rosette 1, against any rotation on its mounting and support axis, that is to say say on the neck 8 Such blocking of the lever or actuation handle 7 with respect to the round escutcheon or rosette 1 can, in this case, be obtained in two offset positions

  of 1800 relative to each other.

  When the locking rod 18 is in the position of withdrawal in the axial direction in which it is represented in FIG. 2 of the appended drawings, the lever or actuation handle 7 can on the other hand turn without hindrance on its axis of mounting and support, i.e. on the neck 8, with respect to the round badge

or rosette 1.

  The sliding movement or sliding in the direction

  axial effect of the locking rod 18 is determined by the half

  profiled cylinder 12, by means of the stirrup 16 which carries this

  locking rod When a suitable key has been inserted in the

  me 12 'from the cylinder, we can, in the classic and usual way,

  rotate, via this cylindrical core, the pan-

  neton 22 of the profile half-cylinder 12.

  As we can very well realize by referring to Figure 3 of the accompanying drawings, the bit 22 of the profile half-cylinder 12, which can be rotated through the core

  cylindrical 12 'of this profiled half-cylinder, is, in its posi-

  base, inside a recess 23 which has the narrower body part 12 "of the profiled half-cylinder 12 The bit 22 in this case occupies a lateral position, next to the window cutouts 24 'and 24 "which are formed respectively in the two

  legs 25 'and 25 "of the stirrup 16, but outside of these openings

pure window.

  The window cutout 24 'which is provided in the branch' of the stirrup 16 also has, at the right end, a control face inclined in the longitudinal direction 26 ', as well as the window cutout 24 " which is provided for in branch 25 "-

  of the stirrup 16 has, at the left end, a face of com-

  length 26 "inclined.

  If the bit 22 is then made to rotate, by means of the cylindrical core 12 ′ of the profiled half-cylinder 12, to the left as shown in FIG. 3, the bit meets the inclined control face 26 ′ window cutout 24 'and pushes the U-shaped stirrup 16, along with the rod

  blocking 18, so as to pass them from the position in the

  which they are represented in FIG. 1 at the position in which

  the they are shown in Figure 2 The locking rod 18 passes in this way from the locking position to the unlocking position

or release.

  If, through the cylindrical core 12 'of the half-cy-

  profiled strip 12, the bit 22 is then rotated to the right according to the representation in FIG. 3 again from its basic position, it meets the inclined control face 26 "of the branch 25" of the stirrup 16 Le bit 22 then pushes the stirrup 16 and, with it, the locking rod 18 so as to make them

  return from the release or release position, in the

  ZO which they are shown in Figure 2 of the accompanying drawings, in the locking position, 'in which they are shown in the

figure 1.

  The position of the inclined control faces 26 'and 26 "presented by the respective window cutouts 24' and 24" of the arms 25 'and 25 "of the U-shaped bracket 16 is such that not only these inclined control faces 26 'and 26 "occupy positions of inclination in opposite directions with respect to each other, but also that they are offset from each other

  in the longitudinal direction of the arms 25 'and 25 "of the stirrup in form

  me from U 16 and this, so that the measure of their offset

  more or less corresponds to the usual width of the bits 22 used

  read in the profile half-cylinders 12, as one can without diffi-

  cultured realize this by referring to Figures 1 and 2 of the

  sins attached The total length of the window cutouts 24 'and 24 "which are formed in the branches 25' and 25" of the stirrup in it forrihe of U 16 is chosen by a measure such as the bit 22 of the half-cylinder 1 Z profile can be placed in these openings

  window for any axial position of the U-shaped bracket 16.

  So that the locking rod 18 is secured in its position, both when it is in the locking position, in which it is shown in FIG. 1, and when it is in the unlocking or disengaging position, in which she is

  shown in Figure 2 of the accompanying drawings, even if the pan-

  neton 22 of the profiled half-cylinder 12 is in the basic position with a view to removing the key from the cylindrical core 12 'from this

  profile half-cylinder, it is provided in the lever or

  tction 7, a ball stop device 27 which cooperates with two stop notches 28 'and 28 "located at a distance one behind the other which are formed in the U-shaped stirrup 16 carrying the locking rod 18, which can be clearly seen in

  referring to Figures 1 and 2 of the accompanying drawings.

  For actuation of the locking rod 18, that is to say

  so that this locking rod covers its entire sliding race

  ment or sliding in the two possible directions of movement, it must not occur, under the effect of the cooperation of the bit 22 with the inclined control faces 26 'and 26 "of the window cutouts 24' and 24" of the branches 25 'and 25 "from the stirrup

  U 16, that a rotation of the bit 22 by an angle of a maximum value

  90 'mum To limit the angular rotation of the bit 22

  in both possible directions of rotation, it is therefore

  m, in the lever or actuating handle 7, stop faces respectively designated by the reference number 29 'and by the reference number 29 ", as can be seen by referring to

  Figure 3 of the accompanying drawings.

  Limiting the angle of rotation of the bit 22 of the

  profiled mid-cylinder 12 results in the advantage that the dimensions of the lever

  or actuation handle 7 in this area must not be pre-

  views appreciably superior to those which are provided in the case where they are rotary handles with key lock which are provided

  of specially adapted closing cylinders.

  12 - Referring to FIG. 4 of the accompanying drawings, it can also be seen that the U-shaped stirrup 16 which carries the locking rod 18 does not necessarily have to be provided under

  a shape such that it surrounds in a U, from the bottom, the narrow body part

  te 12 "of the profiled half-cylinder 12. The branches 25 'and 25" of the stirrup 16 which have the respective window cutouts 24' and 24 "can on the contrary be provided in a form such that they do not engage only in two lateral recesses in the form of grooves, respectively

  designated by the reference number 14 'and by the number of references

  rence 14 ", formed in the lever or actuating handle 7, comprising

  me we can clearly see this by referring to Figure 4 of the accompanying drawings In such a case, the two branches 25 'and 25 "of the stirrup 16 are connected to each other only by the bar

  transverse which carry the locking rod 18.

  This embodiment offers the possibility of fixing the

  profiled mid-cylinder 12, from the bottom, by its narrow body part 12 ', in the lever or actuating handle 7, using a clamping screw or an equivalent element In the case of this form of

  realization, it is however necessary to provide the rear device

  27, as well as the 28 'and 28 "sockets or catches serving

  to the fixing in place of the locking rod 18 in a different manner

  rent of that which is adopted in the case of the example of realization

  tion which is illustrated in Figures 1 to 3 of the accompanying drawings.

  The revolving handle with key lock which is shown in FIGS. 5 to 9 of the appended drawings includes an escutcheon

  round or rosette 101 which can for example be applied to the front face

  sheet, on the local side, of a window sash or a door leaf and which can be fixed by screwing to the window sash or door sash or to the boftier of the mechanism of an active rod fitting or rod control mounted in the window sash or in the door leaf The round escutcheon or rosette 101 has for this purpose, in the areas of adjustment projections, through holes 102

  intended for the installation of fixing screws, including the heads, of round shape

  conical, which will appear after fixing in the form of embedded heads 13, are placed in flared recesses in the form of a trunk

  of cone 103 which are formed in a counter-support plate

  tallique 104 that was placed from above in the round or round crest

  sace 101 In order that the submerged heads of the two fixing screws are invisible and cannot be accessed, so that they cannot be loosened undesirably, the counter-support plate 104 is covered with a cover plate or closure 105, which, in a manner known per se, can be moved so as to pass from the closed position, in which it is represented in

  the drawing, to a release position, and vice versa.

  The lever or actuating handle 107 is mounted, by its neck 108, so as to be able to rotate, in a sleeve 106 molded with the round escutcheon or rosette, sleeve which passes through both the counter-support plate 104 and the support plate cover or closure 105 Concentrically to the axis of rotation of the lever or actuation handle 107, in the neck 108 thereof, is mounted a rod of square cross section 109 which, in conventional and current fashion, engages in the nut, of square cross section

  also, an actuating mechanism of the rod-activated hardware

  ve or control rod The rod of square cross section 109 can in this case be mounted so that it can be detached, but

  not to be able to turn, in the neck 108 of the lever or handle

  However, it can also be formed directly -

  ment in it and it can additionally be anchored therein, without the possibility of relative rotation, by means of a section collar

  relatively large transverse 110, in poly-

  gonal or still having a knurling at the periphery.

  In the lever or actuating handle 107 is formed, in

  a direction parallel to that of the neck 108 and the cross-section rod

  dirty square 109, from the front face of these, a recess 111 whose profile has a shape which corresponds essentially to that of the cross section of a profiled half-cylinder 112, of a type common in trade, profiled half-cylinder which is represented by a dashed line in FIG. 5 and in FIG. 6 of the attached drawings. Part 111 ′, with a cross section of 14 -

  relatively large in size and substantially circular in shape

  re, the recess 111 is provided along the same axis as the neck 108 and, consequently, along the same axis as the square cross-section rod 109 of the lever or actuating handle 107, while the part 111 ", of smaller but elongated width dimensions of the recess 111 follows a direction substantially parallel to the longitudinal direction of the grip spout 113 of the lever

or actuator 107.

* In the case of the embodiment of a turn handle-

  lockable key which is illustrated in Figures 5 to 8 of the accompanying drawings, it is still formed in the lever or actuating lever 107, from the rear face thereof which faces towards the 'round escutcheon or rosette 101, two recesses 114' and 114 "having a semicircular cross-section which are at opposite longitudinal sides of the cross-section part 111" and which can be closed by a bottom plate, which, on the one hand, can be fixed by a rivet 115 'to the

  actuating lever or lever 107 and, on the other hand, also surrounds

  the neck 108 of this lever or lever, place where it takes

  additionally press on the sleeve 106 of the round or round badge

sace 101.

  In the abovementioned recesses 114 ′ and 114 ″ is guided, so as to be able to move therein in the longitudinal direction, a stirrup 116, substantially in the shape of a U, which surrounds, from the rear, the narrow body part 112 "of the profiled half-cylinder 112, as can be seen particularly clearly with reference to FIG. 8 of the drawings appended to the core 117 of the U-shaped stirrup 116 is also rigidly fixed the locking rod 118, which passes through a hole

  119 formed in the bottom plate 115 and which, in the position of

  gage taken by sliding or sliding in the axial direction,

  position in which it is represented in FIG. 5 of the

  sins attached, can engage by adaptation of shapes in stop holes 120 'and 120 "presented by the cover plate or

  105 and / or in stop holes 121 'and 121 "that pre-

  feels the counter support plate 104 When the locking rod

_ 15 -

  118 is in the release position it has taken

  sliding or sliding, position in which it is represented

  shown in Figure 5 of the accompanying drawings, the lever or lever

  actuator 107 is blocked, with respect to the round or round badge

  sack 1 X 01, against any rotation on its mounting and sup-

  port, that is to say on the neck 108 Such blocking of the lever or ma-

  actuation net 107 with respect to the round escutcheon or rosette 101 may furthermore, in the case of the exemplary embodiment in question,

  be obtained in two positions with an offset of 180 ', one relative to

port to another.

  When the locking rod 118 is in the axially withdrawn position, position in which it is shown

  in Figure 6 of the accompanying drawings, the lever or action handle-

  nement 107 can on the other hand turn without hindrance on its axis of

  support mounting, i.e. on the neck 108, with respect to the

round patch or rosette 101.

  The sliding movement or sliding in the direction

  axial that the locking rod 118 performs is determined by the half

  profiled cylinder 112, by means of the stirrup 116 which carries this locking rod When a suitable key has been introduced into the cylindrical core 112 ′ of the profiled half-cylinder 112, it is possible,

  in the conventional and usual way, rotate, through

  diary of this cylindrical core, the bit 122 of the half-cylinder

profile 112.

  As we can very well realize by referring

  in Figures 7 and 9 of the accompanying drawings, the bit 122 of the half

  profiled cylinder 112, which can be rotated via the cylindrical core 112 'of this profiled half-cylinder, is located,

  in its basic position, inside a recess 123 that pre-

  feels the narrower body part 112 "of the profiled half-cylinder 112 The bit 122 in this case occupies a lateral position,

  side of window cutouts 124 'and 124 "which are formed respec-

  tively in the two branches 125 ′ and 125 ″ of the stirrup 116.

  The window cutout 124 'which is provided in the branch' of the stirrup 116 further has, at the right end, a 16 - oblique or inclined steering control face to the side and in the longitudinal direction, the control face 126 ', as well as the window cutout 124 "which is provided in the branch 125 It

  of the stirrup 116 has, at the left end, a face of com-

  oblique or inclined directional demand in the side and in the direction

  longitudinal, the control face 126 ".

  As can be seen by referring to the fig-

  re 7 of the attached drawings, the two branches 125 'and 125 "of the

  sort 116 are of semicircular cross section and they are guided in the recesses 114 'and 114 "which the lever has or

  actuation handle 107, to which they adapt.

  If the bit 122 is rotated, by means of the cylindrical core 112 ′ of the profiled half-cylinder 112, to the left according to the representation in FIG. 7, the bit meets, by its transverse edge 122 ′, the direction control face oblique or inclined to the side 126 'of the window cutout 124'

  formed in the branch 125 ′ of the stirrup 116 During its movement

  rotation bit, the bit 122 therefore pushes the stirrup in for-

  me of U 116, at the same time as the locking rod 118, so as to pass them from the position in which they are represented in FIG. 5 to the position in which they are represented in FIG. 6 The locking rod 118 pass in this way from

  the locking position to the unlocking or disengaging position.

  If, through the cylindrical core 112 'of the half-cy-

  profiled strip 112, the bit 122 is then rotated to the right according to the representation in FIG. 7 again from its basic position, it meets by its end edge 122 "the direction control face oblique to the side 126 "shown in the cutout 124" of the branch 125 "of the stirrup 116 During its rotational movement, the bit 122 then pushes the stirrup 116 and, with it, the locking rod 118 so as to make them return from the unlocking or disengaging position, in which they are represented in FIG. 6 of the appended drawings, to the position of

  blocking, in which they are shown in Figure 5.

  The position of the oblique direction control faces 126 '17 - and 126 "presented by the respective cutouts 124' and 124" of the legs 125 'and 125 "of the U-shaped stirrup 116 is such that these oblique direction faces occupy positions of identical inclinations, but in opposite directions with respect to each other, and that, by their ends facing the narrow body part 112 "of the profiled half-cylinder 112, they are offset one by

  relative to each other in the longitudinal direction so that the me-

  sure of their offset corresponds to the value of the stroke of the locking rod 118, as can be seen particularly

  well account with reference to Figure 8 of the accompanying drawings.

  The total length of the window cutouts 124 ′ and 124 ″ which are formed in the branches 125 ′ and 125 ″ of the stirrup 116 is chosen by a measure such that the bit 122 of the profiled half-cylinder 112 can be placed in these cutouts for any axial position of

the U-shaped stirrup 116.

  So that the locking rod 118 is secured in its position, both when it is in the locking position, in which it is shown in FIG. 5, and when it is in the unlocking or disengaging position, in which it is shown in Figure 6 of the accompanying drawings, if the bit 122 of the profiled half-cylinder 112 has been brought to the basic position

  for the removal of the key from the cylindrical core 112 'of this half

  profiled cylinder, it is provided in the lever or actuator

  ment 107, ball stop devices (which are not shown in the drawing) which each cooperate with two stop notches located at a distance one behind the other which are formed in the U-shaped bracket 116 carrying the locking rod 118, for the two end positions that this control rod can take

by sliding or sliding.

  For actuation of the locking rod 118, that is to say

  so that this control rod covers its entire sliding stroke-

  ment or movement in the two possible directions of movement, it must not occur, under the effect of the cooperation of the bit 122 with the control faces 126 'and 126 "of the window cutouts 124' and 124" of the branches 125 ' and 125 "from the U-shaped stirrup 116, 18 - a rotation of the bit 122 by an angle of a maximum value of 90- To limit the angular rotation of the bit 122 in the two possible directions of rotation, it is therefore formed, in the lever or actuating handle 107, stop faces respectively designated by the reference number 129 'and by the reference number 129 ", as can be clearly seen

  account with reference to Figures 7 and 9 of the accompanying drawings.

  The limitation of the angle of rotation of the bit 122 of the profiled half-cylinder 112 results in the advantage that the dimensions of the lever or actuating handle 107 in this zone must not be provided for substantially greater than those which are provided in the case it is about revolving handles with lock which are

  fitted with specially adapted locking cylinders.

  As we can still see by referring to

  Figures 7 and 9 of the accompanying drawings, the profile of the com

  strip 126 'and 126 "which are provided in the window cutouts 124' and 124" formed in the branches 125 'and 125 "of the U-shaped stirrup 116 is adjusted to the radius of the circle of rotation of the bit 122 From this This results in the advantageous possibility of giving the control faces 126 ′ and 126 "a shape such that they each follow

  a helical line wrapped around the axis of rotation of the purlin-

  tone 122, the generators of the helical lines being formed by

  the end edges 122 'and 122 "of the bit 122.

  As can still be seen by referring to FIG. 9 of the appended drawings, the cross section of the guides 114 ′ and 11411 which are provided in the actuating lever or lever 107 and the cross section of the branches 125 'and "of the U-shaped stirrup 116 need not necessarily be provided in a semicircular shape, as is the case illustrated in FIG. 7 of the attached drawings. The abovementioned cross sections can on the contrary be provided

  triangular in shape or as can be seen in the figure

  gure 9 of prismatic shape in trapezoid.

  It is important, in the case of the two exemplary embodiments which are illustrated paf in FIGS. 7 and 9, that the recesses 114 '19 - and 114 "which are formed in the lever or actuating lever 107 and the branches 125' and 125 "of the U-shaped stirrup 116 are located only laterally next to the narrow body part 112" of the profiled half-cylinder 112, in such a way that they are outside the fixing socket area which, according to the standard,

  are provided for the profile half-cylinder 112.

  Instead of the fixing sockets which are provided according to the standard for the fixing in its position of the profiled half-cylinder 112 in the lever or actuating lever 107, it is also possible that the profiled half-cylinder 112 has, at the lower end of its relatively narrow body part * 112 ", a stop plug 128, in the form of a groove, with which a snap stop member 127, provided on the lever or actuating handle 107, will cooperate,

  stop member which will act by fall effect The stop member of

  click 127 can also be in a form such that it will be placed automatically, with the intervention of the profiled half-cylinder 112, in the blocking socket which can be seen in FIG. 5 and in FIG. attached drawings, but in this case this

  blocking socket can only be lifted using a special tool.

  For security reasons, the description is waived

  of the particularity of realization allowing the uncoupling of

  stop devices with latching members 127.

  It can also be imagined to couple the stirrup 16 and the

  sort 116, the first, to the profiled cylinder 12 and the second, to the profiled cylinder 112, by means of suitable stop or snap connections, in such a way that they can only be moved in common in the axial direction. control 26 'and 26 "which must cooperate

  with the bit 22 of the profiled cylinder 12 and which are intended to pro-

  evoke the displacement in the axial direction are, in this case, provided fixed in the neck of the lever or actuating handle 7, as well as

  the control faces 126 'and'126 "which must cooperate with the pan-

  neton 122 of the profiled cylinder 112 and which are intended to cause displacement in the axial direction are, in this case, provided fixed in the neck of the lever or actuating handle 107 In this case, a stop device is also provided automatic which fixes at least the - engagement position of the locking rod 18, in the case of the exemplary embodiment which is illustrated by FIG. J of the attached drawings, and which fixes at least the engagement position of the rod

  blocking 118, in the case of the embodiment which is il-

  illustrated by FIG. 5 of the appended drawings, and this automatic stop device is then mounted and / or provided in a form such that it can, in the case of the embodiment which is illustrated by the figure 1, be temporarily put out of engagement by the bit 22 of the profiled cylinder 12 and that it can, in the case of the

  embodiment which is illustrated in Figure 5, be temporary

  rement out of engagement by the bit 122 of the profiled cylinder 11 Z. 21 -
