Description

Description.

  The present invention relates to a window shutter, door or the like, especially a skylight, provided on the

  outer face of the window and comprising a covering means

  ture formed of lamellae whose ends slide in

  guide rails, connected to a rolling shutter box, the

  the rolling roll being fixed to the window by at least one fixing means. It is known to fix a roller shutter on the outside of a skylight. The roller shutter is placed and aligned

  on the skylight frame. Then we drill

  loosely holes in which are placed sheet metal screws fixing the shutter. As this work must be done on the

  roof and require technical knowledge, they cannot

  can only be carried out by specialists who are not dizzy. In addition, during assembly, there is always the risk that the flap

  rolling slides when drilling, which does not guarantee

  tit plus correct alignment in mounted condition. In the case of a

  window mounted in a wall and not a skylight, we meet

  be the same problems except that mounting on the ground floor does not require staff without vertigo. Finally, the holes

  have the disadvantage of creating vanishing points.

  According to document DE 28 03 078 Ai, a rolling shutter is known for a tilting skylight, the shutter housing of which is fixed to the frame of the dormer of the skylight by angle rails. The angle rails have for this purpose

  several screw holes in which the screws of my

  floor. These assembly works can only be carried out on the roof. The object of the present invention is to create a rolling shutter which is simply and precisely mounted, and which

  can in particular be set up from the inside.

  This problem is solved according to the invention in the case of a rolling shutter of the type defined above, characterized in

  that the fixing means is constituted by a piece of

  placement preferably in the form of a tilting lug, in the manner of a lock, coming to hang behind an edge of

window fixing.

  This achievement considerably facilitates the

  rolling shutter which can then be done by non-specialized personnel; these works can even be done from the inside. Thus, it is not necessary to resort to the intervention of specialists. The realization of the retaining means in the form of a lockable displacement part, in particular having tilting lugs, makes it possible to mount the roller shutter by a few operations. The roller shutter which is mounted on the outside of the window sash is easily fixed in that the movement piece comes to take hold behind the ridge

  window fixing. The fixing edge preferably exists

  on each window sash regardless of whether or not the window receives a roller shutter provided directly at the installation of the window or later. The edge of

  fixing thus exists from the manufacturing of the window. Vo-

  the rolling part includes the movement piece in the shape of a tab

  by its manufacture so that for the

  of the roller shutter, just put the moving part

lying in its grip position.

  The above embodiments assume that there is at least one displacement part. This is sufficient if, for example,

  is provided such a fastening means on one side of the housing of the

  let rolling and if on the other side of the housing there is for example

  ple a fixing means, not mobile, which also hangs

  under a corresponding fixing edge of the door leaf

  not to be. This last means is first placed below then the

  displacement part, in the form of a tilting tab, is placed

  created in the fixing position. Alternatively, it is also pos-

  likely to provide on both sides of the roller shutter,

  fixing means in the form of tilting lugs, moved

  wheat, according to the invention. In addition or alternatively, one can also

  ment provide one or more fixing means according to the invention in other places of the roller shutter, these means being placed behind fixing edges existing on the

beating from the window.

  According to a development of the invention, it is provided that the displacement part simultaneously constitutes a part

  Clamping. The additional clamping function ensures

  particularly solid and precise positioning for mounting the roller shutter on the window. The clamping function is carried out by the use of the lock-shaped displacement part. Insofar as the clamping effect of the clamping piece acts in the direction or substantially in the direction of the front face of the window, this guarantees fixing against the forces exerted in the plane of the window

  or parallel to the plane of the window. The expression face fron-

  window tale means the peripheral sides of the window sash or some of these sides (for example faces

the two side members).

  In addition or alternatively, it is possible that the effect

  of the clamping piece acts in the opposite direction

  posed or substantially in the direction opposite to normal to the surface of the window. The "normal to the surface" is a vector perpendicular to the surface of the window. By such a tightening effect during assembly, the roller shutter is pulled against the outside face of the window sash; there he is then

  pressed firmly and held without play.

  According to a preferred embodiment of the invention, the retaining edge is produced in a cavity

  window at the sash frame. During the fa-

  window brication, preferably limit this cavity

  locally for example in the form of a short slot

  placed in the frame of the leaf or formed in it

  appropriately so that this cavity does not appear to be annoying, even when the window is not equipped with any

roller shutter.

  The frame of the leaf preferably comprises a

  upper crosspiece, the front face of which is raised relatively

  port on the front face of the two adjacent frame rails

  of the clapper. The crossmember has two front surfaces of pre-

  vertical rails aligned in particular with the front faces

  of the two side members. Each of the two front faces of the tra-

  pours preferably includes a cavity for fixing the roller shutter; this cavity can in particular be produced

  with an open edge, i.e. it starts from the lower edge

  of the respective front face. The cavity can in particular be produced in the form of a pocket, that is to say that it consists of two side walls and a pocket bottom. The

  front surface of the cross member may preferably be reali-

  covered by a covering means, in particular a covering means

  plastic material which immediately passes into the cavity.

  The displacement part is preferably provided on the rolling shutter housing, in particular at each side of the rolling shutter housing. This has the advantage that the roller shutter is fixed in all cases in the area of the roller shutter housing, that is to say on a relatively large part of the roller shutter and which, when the roller shutter is open, becomes relatively heavy to

  because of the slats housed there.

  If the displacement part is associated with a cheek which tilting the rolling shutter housing, this constitutes on the one hand a simple fixing of the rolling shutter on

  the window and on the other hand guarantees a mobile tilting mounting

  for the roller shutter in relation to the window sash

  be; this assembly allows a tilting movement when the window is placed in the tilted position. The tilting axis of the window is preferably located at the level of the upper horizontal crossbar. The window can also be put in a pivoting position for example to clean the

  outer face of the glass and thus the movable mounting below

  movement of the roller shutter housing on the cheeks allows this movement of the shutter. To switch to the pivoting position, the

  leaf frame is tilted around a horizontal axis

  substantially in the middle of the leaf.

  For precise fixing, it is planned to mount the displacement part on a support leg. This foot can be formed for example by the cheek already mentioned which protrudes. This foot rests on the upper side of the leaf frame; the grip for the fixing movement in the manner of a tilting lug is made transverse to the direction of support. The foot includes in particular shape elements (fixing lugs, support lugs) cooperating with

  elements of opposite shape to the leaf frame.

  The expression "elements of form" or "elements of opposite form" designates elements of form or conceptions of form which allow on the one hand a determined support and on the other hand

  It is also preferable to leave only one mounting position.

  The supporting foot can thus include tabs coming from

  above the edges in particular the edges of the edge of the chassis of the

  beating and blocking without being able to slide.

  According to a development of the invention, the displacement part is in the form of a hook, one branch of which constitutes a hooking branch which hooks under the fixing edge. The other branch of the hook-shaped part is held on the rolling shutter by a mounting means capable of being tightened. When the mounting means is tightened by hand or using an appropriate tool, it moves the hook-shaped part so that its grip branch comes to take under

  the fixing edge of the leaf frame.

  The hooking branch is preferably bent so that when the mounting means are tightened, the fixing edge approaches or is applied more strongly against it. The roller shutter is thus pressed in the direction opposite to normal to the surface of the window against the external face of the

beating from the window.

  The present invention will be described below in detail.

  but for another example of realization.

  FIG. 1 shows a rolling shutter 1 in the form of a dormer shutter. It comprises a covering means 3 composed of lamellae 4. The ends 5, 6 of the lamellae 4 slide in the guide rails 7, 8. The upper ends 9,

  guide rails 7, 8 are connected to the housing 11 of the

  let rolling. When the roller shutter 1 is opened, the housing 11

accommodates the slats 4.

  The roller shutter 1 is associated with the exterior side of a dormer 12 so that the housing 11 is located above the upper side 13 of the upper cross member 14 of the frame 15 of the wing of the dormer 12; the two guide rails 7, 8 are parallel to the side members 16, 17 of the frame 15 of the leaf and are located above these side members. The lower ends 18, 19 are fixed using fixing means in the area

lower part of the dormer 12.

  According to Figures 1 to 6, the housing 11 of the roller shutter is fixed to the frame 15 of the leaf using fixing means 20. Such fixing means 20 are provided in the area of the two front faces 21 of the housing 11; these means of

  fixing are made symmetrically plane. It's for-

  which, for the sake of simplification, we will limit below the

  description only to fastening means 20.

  Figures 3 to 5 show particularly clear-

  ment that the fixing means 20 is provided on a cheek 22 for-

  mant a support leg 23. The cheek 22 is a single piece of folded sheet metal, comprising a vertical branch 24 which joins

  in the lower part, a folded foot 25. The vertical branch

  wedge 24 is crossed by a bore 26 receiving a stud not shown so that the housing 11 of the roller shutter is movable in tilting on this stud. The foot 25 has a plate 27 folded preferably at right angles to the vertical branch 24; a fixing lug 29 extends the

  lateral edge 28. The fixing tab 29 has a width (b) ind

  lower than that of the foot plate 27 as shown in FIG

  gure 5. Starting from the foot plate 27, the fixing lug 29 (according to FIG. 6) is folded at an obtuse angle so that overall (with the vertical branch 24), there is a bent profile. The two end zones 30, 31 of the foot plate 27 are folded according to FIG. 5 to form support legs 32, 33. A support leg 35 is formed from the rear edge 34 of the support leg 32. In addition, a support leg 36 (folded substantially at right angles) comes from

  of the rear edge 34 of the support tab 33.

  Two other support legs 37, 38 are bent downward from the rear edge 34 of the foot plate 27; the support leg 37 does not appear in FIG. 5 because it is hidden by a leg support 68 starting from the front edge of the foot plate 27, that is to say from its lateral edge 28. The

  support leg 38 is located on the right side of the fixing leg

  tion 29; another support lug 39 provided on the right side with respect to the fixing lug 29 is bent from the

  lateral edge 28 of the foot plate 27.

  A threaded rod 41 is provided on the outer side

  laughing 40 of the fixing lug 29; this threaded rod receives

  a displacement part 42. The displacement part 42 comprises

  carries an oblong hole 43 for this purpose. According to FIG. 6, the displacement part 42 is produced in the form of a hook 44. This hook comprises a branch 45 crossed by the oblong hole 43

  already mentioned. A hooking branch 46 is folded up relative

  port to branch 45 at an acute angle a.

  Figure 7 shows that on both sides of the branch

  a guide wing 47, 48 is folded each time.

  free tance (d) between the two guide wings 47, 48 is light

  slightly greater than the width (b) of the fixing lug 29. FIG. 6 shows that after the positioning of the displacement part 42 on the threaded rod 41, a wing nut 49 is placed on the threaded rod 41 The wing nut 49 is screwed only a few turns on the threaded rod 41 so that the displacement part 42 remains still free but is held in the longitudinal direction of the median axis 50 and by the oblong hole 43, sliding way on the threaded rod 41. The two guide wings 47, 48 overlap (so that the assembly is still free) the lateral edges of the fixing lug 29 so that this displacement part 42 is guided and that it constitutes in at the same time a rotation lock. In the assembled state, the hooking branch 46 is hooked under the lower edge 51 of the fixing lug 29 and thus protrudes relative to the rear face of the lug

mounting 29.

  Figures 3 and 4 show in a particular way

  lier clear that the upper cross member 14 of the frame 15 of the leaf is higher than the longitudinal members 16 and 17 adjacent;

  this means that the upper face 13 of the cross member is

  wedged upwards with respect to the upper face 52 of the long

  gerons 16, 17. This stems from the fact that the upper cross-member 14 has a very high front face branch 53 which is followed by the upper face 13 which spans the upper partial zones of the side members 16 and 17 then passes through

  a descending branch 54 reaching as far as the upper face

  upper 52 of the side members 16, 17. The front faces of the rail

  pours 14 are closed each time using a cover piece 55 having a first zone 56 located above the side member 16 or 17 and supported by a bent branch 57 on the upper face 13 of the cross member 14. The lower face 13 'of the wall of the cross member 14 is taken from below by a branch 57'; the branches 57, 57 'form a cavity 57' 'for the wall of the cross-member 14. A second zone 58 of the covering part 55 which forms one body with the first zone 56 constitutes a corner part 59; by its branches 60, 61 in the shape of an L, this part 59 passes over the corners formed

  by the upper cross member 14 and the side members 16, 17.

  To mount the roller shutter 1 on the dormer 12, the cheeks 22 are placed in the form of a support foot 23 by their foot on the upper cross member 14, in particular on the respective cover piece 55. The underside of the plate

  leg 27 then rests on the upper face of branch 54.

  The two support legs 32, 33 folded, of each foot 23 have a width and a shape adapted to the cover piece 55

  (according to Figure 3) to ensure a fixed hold in the di-

  rection of the length of the side members 16, 17. In the transverse direction, the support legs 35-39, 68 as well as the leg

  fixing 29 guarantee the maintenance. Support legs 35-

  38 come over the edge 62 facing inward of the branch 57 of the cover piece 55; the support lugs 39 and 68 as well as the fixing lug 29 bear on the outside side 63 of the first zone 56 of

  the cover piece 55. FIG. 5 shows by a broken line

  terrompu, an alternative embodiment according to which the support legs 39 and 68 are extended to reach the

  side members 16 and 17. Thus, where appropriate, the lateral surfaces

  the side members 16 and 17 absorb the more significant loads

  your. A cavity 65 with an open edge comes from the lower edge 64 (FIG. 3) of the first zone 56 of the cover piece 55 preferably made of plastic; the

  width (c) of this cavity is slightly greater than the width

  geur (d) (Figure 7) of the latching branch 46 of the displacement part 42. The open-edge cavity 65 has a

  hooking edge 66 as shown in FIG. 4.

  As described above, when the support foot 23,

  is placed on the corresponding cover piece 55

  dante, the wing nut 49 is used. According to FIG. 4, 11 the result is that the hooking branch 46 penetrates into the open-edge cavity so that the branch 46 is hooked behind the fixing edge 66. The angle included between the branch

  of attachment 46 and the branch 45 is an acute angle. We have exac-

  the same angle or a similar angle between the outer side

  of the fixing lug 29 and the surface of the fixing ridge

  tion 66. In particular the surface of the fixing edge 66

  is parallel to the plane of the window.

  Figure 4a shows another embodiment

  means for fixing the roller shutter; this variant matches

  pond to that of figure 4 with the exception of the evo-

  listed below. The cavity 65 forming the fixing edge 66 is

  produced as a pocket 65 ′ of the cover piece 55, that is to say

  say that there is a closed contour avoiding for example the penetration

  rainwater. The pocket 65 'has a side wall

  as well as another side wall 71 parallel to the previous

  toothed; the two side walls 70, 71 are connected to the bottom

  of the cavity 65 by a partition 72 forming the bottom of the pocket.

  The depth of the pocket 65 'is greater than the length of

  the attachment branch 46. Compared to the example of realization

  tion of Figure 4, the fixing edge 66 thus continues in the form of a side wall 70 of the pocket inside the upper cross member 14. The fixing edge 66 is thus enlarged relative to that of the example of FIG. 4 and it constitutes practically a surrounding surface 66 ′ for the

hanging branch 46.

  According to another variant not shown, thanks to the hook shape of the displacement part 42 and the edge

  fastener 66 mounted correspondingly when

  rage of the wing nut 49 there is a pinching effect so that the displacement part 42 also constitutes a

pinching.

  The longitudinal members 16 and 17 are fixed using fixing means 129 to the lower zone of the dormer 12,

  on the lower cross member 128 of the leaf frame 15.

  Like fixing 129 of guide rails 7 and 8

  is of symmetrical planar shape, the description given below

  using figures 8 and 9 is limited to that of fixing 129

  of the guide rail 8. The same description applies to the mode of

realization of figure 10.

  According to Figures 8 and 9, the guide rail 8 comprises

  carries a receiving slot 130 for the ends 6 of the

  melles 4. It also has a C-shaped profile, 131 housing slidingly longitudinally, a first piece of

  fixing 132; the shaping of the first piece of fixa-

  tion 132 as well as the contour C of the C-profile, 131 prevents the first fixing piece 132 from being released in the

  two directions of the double rebate 133 out of the guide rail

  dage 8. A second fixing piece 136 is fixed to the cross

  lower pour 128 in particular on a front face 134 laterally at an angle (FIG. 9) preferably using sheet metal screws 135. It is also possible to fix on the cross member 128 by a snap connection. The two fixing pieces 132 and 136 are movably connected in tilting by a stud 137. The tilting axis formed by the stud 137 is

  perpendicular to the longitudinal direction of the guide rails

  8. The fixing 129 allows relative sliding of the guide rail 8 in the longitudinal direction of the rail, between the

  beating 122 and the shutter 1; however, the distance li-

  bre between the free ends 18 and 19 of the two guide rails

  dage 7 and 8 remains precisely maintained.

  In detail, FIGS. 8 and 9 show that the bottom of the C-shaped profile, 131 is constituted by the

  vertical wall 139 of the guide rail 8. The wall 139 is

  follows by horizontal walls 140, 141 ending themselves

  same by the vertical branches 142, 143 of the shape of C. The first fixing part 132 has at the top and bottom of the

  protruding parts 144 coming to take in the space included

  be the wall 139 and the branches 142, 143 of the C-shaped. In the fixing section 145 the first fixing part 132 comes out of the opening of the C-shaped profile, 131 to receive the mobile fixing in tilting on a vertical wall 146 of the second block-shaped fixing piece 136. The second fastener 136 preferably has an L-shaped structure; a branch of this form of L is constituted by

  wall 146 and the other branch of this L shape is

  killed by a wall 147; the wall 147 is fixed flat on the

  frontal surface 134 of lower cross member 128.

  Figure 10 shows another embodiment

  a fixation 129; for the sake of simplification, the description

  tion below will be limited to differences from

  the embodiment shown in Figures 8 and 9. The pro-

  C-wire 131 is turned with its opening not as in the example in FIGS. 8 and 9 towards the middle of the window, but in the direction of the external side 148 of the lower cross member 128. Thus, the wall 139 is horizontal and the walls 140, 141 are facing downwards. The first fastening piece 132

  comes out at the bottom of the C-profile, 131 through its fixing segment

  tion 145. At this point, perpendicular to the longitudinal direction of the guide rail 8, is located the stud 137 on which is movably fixed in tilting, the second

  fixing piece 136. By means of means 148 which are not indicated

  Only schematically, the second fixing piece 136 is fixed to the lower cross member 128. The fixing piece 136

  can be slid into a C-shaped guide groove

  lon another exemplary embodiment; it includes at least

  a snap connection for hanging the fixing piece

  136 in the C-shaped guide groove.

  As a snap connection, provide a hooking spout. The C-shaped groove guide means is screwed to the cross member 128, clipped into this cross member or fixed to it by injection. This example of realization is not

more detailed in figure 10.

  The first fastening piece 132 can slide longitudinally along the guide rail 8 in the profile

  C, 131 to achieve the desired relative movement (in combination

  naison with the possibility of tilting ensured by the stud

  137) between the guide rail 8 and the frame 15 of the leaf.
