Description

Description

  The invention relates to a balancing installation for a skylight mounted for rotation about a tilting axis.

  passing substantially in the middle of the leaf to tilt the bat-

  both around a horizontal axis. It is already known to make dormers to allow them to be put in a pivoting position and a tilting position. In the pivoting position, the leaf pivots about a pivot axis which is at the level of the upper cross member of the leaf. In the tilting position,

  the leaf is rotated around a horizontal axis

  sant substantially mid-length of the leaf. The low position

  to turn the window sash

  approximately 180 to put the window in the net position

  toyage, that is to say to turn the outer side of the glass

  to the room and allow its cleaning.

  In general we install skylights in roofs

  steep. The angles of inclination differ depending on the roof.

  res. This means that depending on the angle of inclination,

  different forces act on the window sash in

  tilted position and these efforts can cause the tilting position not to keep itself and the window sash may close accidentally. These problems

  often encountered in the case of a later equipped skylight

  laughingly a roller shutter fixed on the outside of the dormer and resting on the leaf. When the leaf is put in the tilted position, the weight of the shutter pushes the leaf always in the closing direction so that emergency solutions are used such as for example a blocking with

household objects.

  The object of the present invention is to create an

  tallation allowing despite different power ratios to

  because of the different inclinations of the roofs and / or the

  different specific elements (such as retrofitting a rolling shutter or rolling shutter from the outset) to always keep the pivoting position of

the skylight.

  This problem is solved according to the invention by a balancing means of the type defined above, characterized in that the upper cross member of the leaf, receives at least one weight in the closed position of the window. 5 The balancing solution according to the invention provides

  a weight at least on the upper cross member of the leaf in po-

closing location.

  Thanks to the tilting axis which passes substantially halfway up the window sash, the sash is mounted in the manner of a tilt. The forces produced for example by a different roof slope or because of the different load resulting from a rolling shutter lead to the leaf of

  window mounted like a tilt, accidentally swivels-

  especially towards the closed position. The weight provided according to the invention compensates for the forces mentioned above, which balances the window sash retaining

then its tilted position.

  Placing the weight on or at the front face on the rebate side of the upper cross member of the window sash ensures high efficiency thanks to the lever arm of maximum length; the effect of weight depends

  of the set tilt angle. As the stray forces

  also hang from the slope of the roof or load, the solu-

  tion of the invention allows optimum weight balancing.

  The weight is not bothersome because it is pre-

  ference at the level of the front face of the rebate side of the upper cross member of the leaf. This solution using a weight is not limited to placing the weight on the

  outer side of the front face; we can also pre-

  see on the inside of the cross member and the front

  opposite, on the side of the rebate also enters the defi-

  nition of front face on the side of the rebate as provided according to a characteristic described. By means

  simple that are not apparent, the information gives a balance

optimum release.

  The weight is preferably removable which allows it to be removed if necessary to adapt to certain data,

  for example when installing or removing elements

  ment. It is also possible to replace a weight with another one of different mass. The weight may preferably consist of a heavy rod, that is to say that its length is relatively large compared to its other dimensions. The weight can preferably be formed by a rectangular rod. This weight is in particular a material having a high density or comprising a material having such a high density. It is advantageous

  achieve the desired balancing even for smaller dimensions

laterally small.

  It is particularly advantageous for the weight to include length marks depending on the load and / or the mounting angle. The length markers allow the fitter on site to immediately balance the necessary weight when installing the window without using other means. For example, for a roof slope of 45, it cuts the weight which was supplied to it, at the length mark bearing the reference 45. As a result, the partial mass, resulting, mounted in the window is defined according to the load conditions ensuring equilibrium. Correspondingly, for load-dependent cases, for example in the case of skylight shutters, the procedure is the same. For example the weight can include a mark

  "with rolling shutter" and another reference "without rolling shutter-

  lant ". It is also possible to provide a large number of spaced apart marks that the fitter counts; the marks can also be defined by numbers. With the aid of a concordance table it can then be determined for example that the heavy rod must be cut after six segments to arrive at the

desired balancing mass.

  Preferably, on the front face of the cross-member there is provided a cavity forming a housing in the longitudinal direction of the cross-member to receive the weight. This can be done on the outside of the sleeper, but also on the inside. The cavity forming the housing can also be produced in the form of a receiving channel in which

slips the weight.

  The spring solution provides for a balancing installation of a skylight, the outer side of which is equipped with a roller shutter resting on the outer side and provided with a covering means formed of strips, the ends of which slide in rails. guide associated with the side members of the skylight; to take the tilted position around an axis

  horizontal, constituted by the pivoting axis passing sensi-

  in the middle of the window sash, the roller shutter com-

  carries at least one balancing element which is supported by the

  spring force in the area above the rocking axis-

  of the leaf, in particular on an arm element which, in position

  The tilting element is detached from the wing spar and bears the balancing element. Thanks to this support by the balancing element, a force is applied to the window sash which opposes the load exerted by the weight of the shutter; this achieves optimum balancing. Thanks to the invention, the roller shutter does not rest in the tilted position only by its lower segment of its guide rails against the lower zone of the window sash but

  there is support mainly in the upper area of the bat-

  both of the window, in particular on the arm element already mentioned, thanks to the balancing element according to the invention. This element is under the preload of a spring, i.e. it

  pushes with a spring force if necessary with interposi-

  tion of a lever mechanism or the like on the wing

  window or arm element above the tilt axis -

  lement of the leaf; this results in weight compensation so that the open window keeps its position

  opening and does not accidentally tip over.

  Two balancing elements are preferably provided which push on the window sash or on

  each time on an arm element which detaches respectively-

  ment of a wing spar in the area above the swing axis of the wing. In particular, the installation

  balancing is therefore housed on the guide rails.

  The application of the force of the balancing element

  brage by the spring with the advantage that according to the position of the window sash, there is a compensation corresponding to the

  weight. The angle of inclination of the roller shutter depends on the po-

  tilting window sash. The same remark

  that applies to the distance between the window sash and

  the roller shutter; the weight compensation element is

  placed by the force of the spring in the direction of the leaf of the

  be or of the arm element so that the support can be done.

  Depending on the length of the stroke of the balancing element, a pressing force results allowing optimum support for balancing. Examples of embodiments of the invention will be described below with the aid of the appended drawings in which: - Figure 1 is a perspective view of a skylight fitted with a roller shutter, - Figure 2 is a view in partial schematic perspective

  Figure 1 shows a skylight 1 installed in a certain position corresponding to the inclination of the roof of a building. This skylight has a sleeping frame 2

  (Figure 5; not shown in Figure 1) and a battery

  both 3. On the outer side of the dormer 1 is mounted a roller shutter 4 comprising a covering means 5 formed by a large number of strips 6. The ends of the strips 6 are housed in guide rails 7, 8 of the shutter rolling shutter 4. The rolling shutter 4 further comprises a housing 9 receiving the lamellae 6; in the raised position, the slats are wound on a winding axis. The guide rails 7, 8 bear in the closed position of the roof 1 (shown in FIG. 1)

  on the side members 10, 11 of the wing 3 of the skylight.

  When the skylight 1 is put in the tilting position, the leaf 3 swings around a tilting axis 12 located in the area of the upper crossmember of the skylight. The roller shutter 4 rocks with the leaf around a tilting axis 13 situated above and relatively close to the tilting axis 12 (the tilting axes 12 and 13 appear in FIG. 1). Weight ratios of wing 3 and load ratios of wing 3 due to the flap

  roller 4 are chosen to have a substantially equilibrium, 10 that is to say that the leaf 3 automatically remains in the po-

  tipping phase in which it was put.

  The leaf 3 is not put in a posi-

  pivoting but in a tilting position according to Figure 5 so that it rotates around the axis 14 passing

  substantially in the middle of leaf 3, that is to say that the bat-

  both 3 is mounted substantially in the manner of a rocker. To reach this tilting position of FIG. 5, arm elements 15, 16 are detached from the side members 10, 11 of the leaf 3; these arm elements are mounted by one of their ends in the upper region of the frame of frame 2 and

  by their other ends pivotally on the lanyards

  rons 10, 11. The guide rails 7, 8 of the roller shutter 4

  are supported in the pivoted position in the lower zone 17, each

  that times against leaf 3; roller shutter 4 has performed

  its rotational movement around its axis 13. Thus it appears

  It is clear that the lower end area of the window sash 3 is loaded by the weight or by a component of the weight of the roller shutter 4 so that the sash 3 tends to

  leave its pivoted position and close accidentally.

  To avoid this, balancing is provided by a weight 18 placed in the area of the upper cross member 19 of the leaf.

window 3.

  According to Figure 2 the weight 18 is in the face

  frontal 20 of leaf 3, on the rebate side in the trans-

  pour 19 so as not to be visible. In particular, the front face 20 comprises a cavity forming a housing 21 preferably extending over the entire length or only over part of the length of the crosspiece 19 to receive the weight 18. The weight 18 is preferably a heavy rod 22 that is to say of relatively large length compared to its other dimensions, to offer only a small section, however having the appropriate mass. FIG. 2 shows that the weight 18 is made in the form of a socket with a rectangular section 23 in

  engaged in a cavity 21 forming the housing of rectan section

  gular. The weight 18 is preferably fixed using

  quote; one can thus provide screws 24 passing through holes

  those for fixing the weight and coming in the cross member 19.

  Alternatively it is also possible to provide the

  weight 18 in other places of the cross 19 or in the cross

  pours 19 itself, if it is produced in the form of a hollow profile. In Figure 2, the dashed line indicates

  that the crosspiece 19 has on one side, a receiving opening

  tion 25 for a reception channel 26 into which the weight 18 slides so that it no longer appears. The weight is locked by appropriate means in this fitted position to avoid

that it does not come out accidentally.

  Figures 3 and 4 show a balancing according to another embodiment of the invention; this balancing is done using a balancing element 27 which exerts a supporting function (supporting force F) compensating for the load by the rolling shutter 4 acting on the leaf 3 in particular on the

  arm elements 15 and 16 so that the window 1 is placed in

  tilting position, remains in its open position and does not

  cannot accidentally tip over.

  This support function will be explained using FIG. 5. The compensation or balancing element 27 starts from the upper region of the guide rail 7. For the guide rail 8, the same situation exists, that is, it is planned

  also a weight compensation element 27, the con-

  truction corresponds to that of the guide rail 7; for a purpose

  for simplification, the rest will only concern the guide rail.

  dage 7. The compensating element 27 is pushed by a spring force, from the upper zone of the guide rail 7 in the direction (arrow 28) of the arm element 15 of the lateral spar 10. This element s press at this point with the support force F. As a result, depending on the support force, the weight

  according to which the rolling shutter 4 pushes on the leaf 3 dimi-

  so that there is no longer any risk of the window sash 3 being pushed into the closed position. This closing movement

  is indicated in FIG. 5 by the arrow 29. The embodiment se-

  lon the invention offers the advantage that when the window is in

  closed position, the spring force is mainly absorbed

  opened by the lever mechanism, itself does not charge

  not parts of the window and / or roller shutter.

  Figure 4 shows the construction of the

  compensation with a balancing compensation element 27.

  The guide channel 30 of the guide rail 7 of the roller shutter 4 receives in a non-sliding manner a bearing block 31 fixed with suitable means. A helical spring 32 starts from the bearing block 31. This spring is connected to a sliding block 33 housed movable longitudinally in the guide channel 30. A

  first lever 35 is pivotally mounted around the pivot axis

  ment 34 of the bearing block 31; this lever is connected by an axis

  pivot 36 to the compensation element 27. The block of pa-

  link 33 also includes a pivot axis 37 for receiving

  pivotally view a second lever 38; this lever is

  also connected by a pivot pin 39 to the element of com-

  weight thinking 27. When the weight compensating element 27 moves by pressing against the arm element 15,

  loaded (not shown in detail) the sliding block 39 is released

  place in the direction of arrow 40 of the guide channel 30.

  This is also shown in broken lines at

  Figure 3. The coil spring 32 is band. In addition, he learns

  It appears clearly that as a function of the angle x comprised between the guide rail 7 and the arm element 15, a corresponding bearing force 11 is exerted, so that the weight acting on the lower zone of the leaf 3 exerted by the rolling shutter

  4 decreases so that overall, there is a balancing of the

  these resulting in a balancing of the leaf 3. An instal-

  adjustment lation 41 which allows a relative movement of the helical spring 32 relative to the bearing block 31 allows to adjust the preload of the spring and thus the pressing force F to the desired value. The adjustment installation 41 preferably comprises a rod 42 guided in longitudinal sliding

  in the bearing block 31. This can be fixed in po-

  different positions on the bearing block 31 and the spring

  licoidal 32 is fixed at one end.
