Description

Vertical curtain installation

  The invention relates to a vertical curtain system comprising

  vertical blades, which constitute the vertical curtain, and in

  vertical blades are mounted on slides of a slide

  suspension and draw and can rotate under the action of a

  pivoting device, followed by the desired light transmission.

  Already known such a curtain.vertical installation, in which there are provided carts which are kept at a distance from each other by means of ribbons son, these carriages being moved by means of a pull cord to close or open the curtain

  vertical. In the known device, to rotate the blades of the ri-

  water, a special training tree is provided which, through

  An associated worm wheel located in the carriages is actuated by a respective gear, which is rotatably connected to a shaft and pivots the vertical blades by means of a hook protruding from the carriage. If the drive shaft is rotated, the worm gear drives a pinion inside the carriage and the hook pivots so that the vertical blades also rotate,

  which causes either the closing of the curtain to obtain a darkness

  cissement, an opening of the curtain to let the light.

  A disadvantage lies in the fact that this is a very complex technique, because these trolleys are very expensive to manufacture and have a certain fragility of operation. In addition it is necessary to provide, in addition to the draw cord, a particular drive shaft which are respectively associated with a wheel

  worm gear and a pinion, in the vicinity of each vertical blade

  curtain, resulting in considerable expense and, in the case of a large number of worm wheels and gables, could

  to be the cause of disturbances of the operation of the installation.

  Another disadvantage of the vertical curtain installation

  naked, lies in the fact that it is necessary here to provide

  curtain suspension, in which the drive shaft must be guided, and the drawbar, on the other hand, in which case relatively large carriages are provided, so that Curtain hanging rails, wide,

  which is a disadvantage. In addition, there is another disadvantage

  both in that these known vertical installations could not be bent, that is to say they could only extend according to

a rectilinear disposition.

  The present invention aims to develop a vertical curtain system of the type mentioned above, so as to guarantee,

  at significantly lower manufacturing costs, a plant

  safer operation, for which it is also possible

  to obtain any bending of the slide.

  This object is achieved in accordance with the invention by the fact that sliders having sliding rollers are guided so as to be rotated and movable longitudinally, in the groove of a suspension and pulling slide, that vertical slats are respectively suspended from the sliders by means of a corresponding hook-shaped end, that the vertical slats are connected externally each to cords

  orientation control and that it is intended as a pivoting device

  an orientation element which, in conjunction with a fixed element,

  triggers a pivoting of the last slide connected to the cord, this pivots-

  being communicated via the order control cords.

  to all other vertical blades, so that all the curtain blades are oriented by the pivoting of the last slide

connected to the cords.

  The present invention therefore makes it possible to obtain an advantage

  important compared to the state of the art, because the trolleys

  expensive state of the art may be deleted and replaced

  by simple slides, of the type used in slides of

ordinary suspension and draw.

  As a result, the essential advantage is that sliders of suspension and

  typical draw for such a vertical installation and that these

  The usual suspension and drawers can be bent under any radius, which was not possible until then with the usual vertical installations. But above all, the present invention makes it possible to eliminate the expensive device for rotating the blades, which was previously produced with a drive shaft.

  a worm wheel, a pinion and a swivel hook.

  According to the present invention, only the last slide

  bucket connected to the cords comprises a rotational driving device or an orientation element, the rotation of the latter connected slide

  with the cords being communicated, through the cords of orien-

  tation, which link together all the curtain blades, to all

  the other curtain blades so that they can all be

  by rotating the last slide connected to the cords.

  According to the invention, therefore, a slide is used

  curtain suspension system, in which a system is arranged

  draw string, which is rigidly connected at its end to a slider, which engages in the orienting member, arranged in a manner

to cooperate with a fixed stop.

  The cursor therefore causes the orientation element to de-

  translatable against a fixed stop, and the contact of the element

  mobile orientation with the fixed stop activates a steering mechanism

  tation and a pivoting mechanism, which pivot-the last cou-

sling connected to the cords.

  This rotation is then communicated through the intermediary

  cords of orientation, to all other blades.

  For the realization of the guidance element, there is

several possibilities.

  According to a first embodiment, the orientation element

  moved by means of a traction cable by means of a

  which, as a result of its engagement in a recess of the orienting element, drives it against the fixed stop and activates the

pivoting mechanism.

  In this case, it is advantageously provided as an element of orientation.

  tation, a pusher movable through the traction cable and having a rack, with which meshes, as the last slider connected to the cords, an orientation pinion, which is guided

  in the groove of the suspension and draw slide and is now

  pivoted in a locking recess of a

  fixed locking device in the manner of a stop.

  According to a second embodiment, there is provided, as an orientation element, a pusher movable by means of the traction cable and having a recess and a locking head, and a sliding element comprising an arm pivotable about an axis of rotation, is installed in the recess, the. arm being engaged

  - with a curtain blade and the blades of the curtain curtain when the element

  The slider is moved by the slider.

  Advantages of the present invention reside in particular in the fact that the sliders, which are guided in the usual slider of the curtain, can be very closely together, so that the bundle of blades obtained when the curtain is open occupies a very small width (over the length of the curtain rail), which provides a favorable optical impression

  and avoids an inadmissible large masking of the window when the ri

Bladed water is open.

  Another advantage lies in the fact that bending can be carried out on any radius and in addition that it is possible to use

  the usual suspension and drawing rails with the new

  orientation system. Another advantage lies in the fact that only one

  tenth of the manufacturing costs are required for the new installation.

  compared to the costs hitherto required for

usual vertical installations.

  The subject of the present invention is not only an installation

  vertical curtain in its different individual variants.

  them, but also a combined use of these variants. All

  the characteristics and indications mentioned in this

  description, with reference to the drawings, are considered important

  for the invention, either individually or in combination.

  FIG. 1 shows a blocking element 1, which is screwed in a fixed position in the suspension and drawing slide 9, as shown in FIG. 6. Here the blocking element 1 is anchored firmly by screwing with a screw 10 and a nut 11 in the circulation groove 12 of the suspension slide and

print 9.

  This blocking element 1 is located at the end of the curtain,

  that is to say, in front of the zone of action of the draw cord of the curtain.

  In the suspension and pulling slide 9 of FIG. 6, a traction cable 5 is installed so as to be displaceable in the usual way, according to FIG. 3, in guide channels, a slider 4 being rigidly connected to the end of the traction cable, as shown in FIG. 3. The traction cable 5 is brought back inside the slide

  suspension and circulation through a footnote 13, not shown

  detailed in Figure 3, so that one obtains a

closed guidance system.

  What is important here is that, for the described vertical system according to the present invention, it is possible to use a conventional suspension and pulling slide 9 having a corresponding slider 4, so that such suspension and 9 can be bent in any radius and that we can now realize for the first time a new type of vertical suspension

  with such a suspension and pulling slide 9.

  As a result, it is possible to immediately transform

  curtains, in which it is possible to increase

  expensive simple curtains with slides, in one installation

  vertical, thanks to the use of the elements according to the invention.

  This is an entirely new point of view because until then it

  had to be replaced by the slider

  described above, which can be avoided by the present

  because, for the new vertical installation, it is sufficient to use

  the slides 6 and 3 arranged in a particular manner, and in addition the pusher 2 in connection with a locking element 1 fixed at the end

  the suspension and draw slide.

  Therefore, it is also possible for the first time to mount directly vertical installations on the usual suspension and draw rails 9, on which are fixed curtains

  conventional. This results in a simple transformation, which does not

Until then, it was not possible.

  Vertical installation consists of curtain blades

  7, which are shown in a side elevational view on the

  Fig. 5. The blades 7 of the curtain are constituted by blades having a width of about 12 to 20 cm, and naturally it is possible to use

  any width suitable for the blades. Figure 5a shows

  feels such a blade 7 according to a plan view.

  It can be seen that in the center and at the top of each

  7 of the curtain, there is arranged a hook 14, in which

  pledge the hook-shaped end 15 of a new slide 6 which

  is shown in more detail in FIG. 4.

  The blades 7 are interconnected by means of the orientation cords 8, and in Figure 5 the curtain is shown? in its closed position, that is to say that the orientation cords 8, which are respectively connected to the upper outer edges of the

  blades 7 of the curtain, keep the curtains at a distance when the ri-

water is closed.

  The blades 7 are then moved in the direction of the arrow

16 against the fixed stop 1.

  The slider 6 according to the invention is constituted by a sliding roller 17, which has a circular profile, so that the slider 6 is rotatably mounted in the direction of the arrow 19 in FIG. its longitudinal axis 18 in the suspension and draw slide 9, and naturally is guided so as to be movable in the direction of the arrow 16 and in the

opposite direction.

  With the sliding roller 17, which is mounted so as to be displaceable

  in the circulation groove 12 of the suspension and drawing slide 9 and circulates therein, is connected an axle 20 having a reduced diameter, which engages in the circulation groove 12 and makes

  protrude down out of the curtain suspension slider 9.

  A hook-shaped element 21 is connected to this axis 20;

  the hook-shaped element 21 has a collar 22 widened in a dia-

  meter so that the slider 6 can not tip into the groove

  of circulation 12 of the slide 9 and get stuck there.

  The end 15 hook-shaped, which has an opening

  passage 23, is connected to the collar 22 widened in diameter.

  The hook 14 of the blade 7 is guided in this opening of

  passage 23 and the blade is thus suspended at the crooked end.

chet 15.

  All the blades 7 are suspended from such slides 6,

  the exception of the last blade 7 connected to the cords, which is

  to a slider according to Figure 3a.

  This slider again includes, as a gear pinion

  3, a sliding roller 17 and also has all the other features of the sliders 6 except that the axis 20 is shortened and that there is provided, below the axis 20, a collar 24

  axial length and increased thickness, which cooperates with a recess

  blocking element 26, which will be described later, arranged in the element of

blocking 1.

  Below the collar 24, is formed by forming, on the pinion 3, a toothed wheel 27, which cooperates with an associated rack 28 provided on a longitudinal side of the recess 25 in the pusher 2. In accordance with the representation of 6, the pinion 3 engages, by its toothed wheel 27, in the recess 25 of the pusher 2, and the toothed wheel 27 then meshes with the rack 28, which is arranged

on the one hand.

  In addition, the slider 4 engages in a second recess 29 of the pusher 2, to be rigidly connected to this pusher 2 and, under the effect of the displacement of the traction cable 5 in the direction of the arrow 16 and in the opposite direction , the pusher 2 is thus moved in the

  directions represented by the arrows.

  This therefore means that the orientation pinion 3 is permanently engaged with the recess 25 of the pusher 2, the rack 28 meshing permanently with the pinion 27. This situation

is shown in Figure 6.

  If then the slider 4 is moved, together with the pulling cable 5, in the direction of the arrow 16 to come against the

  fixed stop of the locking element 1, the collar 24 of the pinion of orienta-

  3 to the blocking recess 26 of the blocking element 1. For this purpose, the blocking recess 26 is provided elastically and comprises, according to FIG. easier penetration of the collar 25 in the recess

blocking 26.

  A slot 31 is provided downstream of the blocking recess 26

  in the direction of traction, so as to improve the characteristics

  elasticity of the blocking recess 26.

  Thus when the draw cord 16 is moved together

  With the slider 4 in the direction of the arrow 16, the collar 24 of the orientation pinion 3 reaches the locking recess 26 of the locking element 1 situated at the end of the curtain, which, however, has the following effect: effect that this orientation pinion 3 is locked in a position

  fixed, but can rotate. The further movement of the

  evening 2 in accordance with Figure 6, -conduit that now the pinion orientation 3 circulates with its toothed wheel 27 along the rack 28, that is to say that the pinion orientation 3 executes a movement of rotation isolated in the vicinity of the rack 28, the toothed wheel 27 rolling along the rack 28 and, as a result, the pinion of orienta-

  3 rotates in the direction of the arrow 19 about its longitudinal axis.

tudinal 18, in FIG.

  Before the pusher 2 with the pinion gear 3 reaches the locking recess 26 or the locking member 1, the pivoting mechanism of the pinion gear 3 is turned off. The curtain can then be opened or closed by moving its blades 7 without orientation of the latter, in which case the blades 7 of the curtain can advantageously be collected in a particularly dense manner. It is only when the collar 24 of the pinion gear 3 of Figure 3a reaches the locking recess 26 of Figure 2 that the rotational movement of the blades 7 of the curtain is triggered. The blades 7 of the curtain are then oriented according to the direction of traction

  cable 5 in the direction of arrow 16 or in the opposite direction

  according to Figure 6, and more particularly under the ef-

  fet the displacement of the pusher 2 which, by its rack 28, rotates

  the pinion gear 3 in the recess 26.

  As a result, we obtain the desired rotation and all the blades

  7 of the curtain are driven simultaneously through the cor-

  orientation donations 8 (see Figure 5 and Figure 5a) and are then closed

or open.

  Consequently, simple means make it possible to obtain

  a standard slider for pulling and pulling and a means of

  a new type as well as with curtain blades 7 held pivotally in the suspension and draw slide, it is possible to open and close the curtain and simultaneously, the curtain being closed,

  to orient the blades 7 in the direction of their closure.

  In FIGS. 1 to 6, only a first

  embodiment of such an orientation device.

  Naturally, there are several different forms of

  all of these devices having in common that it is necessary to provide a fixed stop and it is necessary to obtain, in the vicinity of this fixed stop, by moving the traction cable and the slider 4, a rotation of the last slide 3 connected to the cords. In the present embodiment, the orientation pinion 3 is moved in the direction of the arrow 32 in the vicinity of a recess.

  in the form of an elongate hole 25, the orientation pinion 3 being

  in rotation with a toothed wheel 27, which rolls along a cremaill-

  lère 28 located in the pusher 2, as soon as the collar 25 of the sprocket

  3aatteint the locking recess 26 of the locking element 1.

  Figures 7, 8 and 9 show other examples of

  tion for obtaining such a rotation of a slider.

  FIG. 7 schematically shows again a curtain blade 7 comprising a fixed locking element 1, a push rod 33

  being formed by an elongated body, on the rear end of which is

  This locking head 34 is also inserted into the blocking recess 26 of the blocking element 1 and

is kept blocked.

  As in Figure 2, the cursor 4 engages in a recess

  29 in the pusher 33, in which case it is important that the recess

  29 extends through the entire pusher and a sliding element

  35 is present in the region of this recess 29. This element

  sliding member 35 has an axis of rotation 36, on which is pivotally mounted

  an arm 37, whose free rear end carries a locking device 38 that can grip the blade 7 of the curtain on its pivoting portion

exterior.

  If the sliding element 35 is in the position of FIG. 7, it is kept blocked by the locking head 34 in the recess of FIG.

  blocking 26 of the blocking element 1.

  If we then move the cursor 4, which engages in the recess

  29, rearward in the direction of the arrow 39, the sliding element

  35 is moved in the direction 39 and reaches the pro-

  along the recess 29, namely the portion 29a. This entails a connection

  curving the length of the arm 37, which then pivots the blade 7 in the direction of the arrow 40 around the hook 14 not shown in detail, in connection with the hook-shaped end 15, 11,

  not shown in detail, the slide.

  FIG. 8 represents a modified exemplary embodiment, in which it can be seen that a pusher 33 is provided, of identical shape, except that on this pusher is furthermore disposed, at one of its ends, a recess 41, which cooperates with a stop

42 fixed rise.

  The difference between FIGS. 7 and 8 therefore lies simply in the fact that, in FIG. 7, a locking head 34 is formed on the pusher 33, whereas in FIG. 8 a locking recess 41 is formed in the pusher 33 and a fixed fixed stop 42

  is attached to the suspension and pull slide.

  It is also important to indicate that the blocking device

  Cage 38 located on the pivoting free end of the arm 37 grips the blade 7 without blocking it, but that, on the contrary, during the pivoting of the arm 37, the locking device 38 is moved along the blade 7 in the direction of the arrow 43 so as to thereby pivot the blade. If it is not desired such movement of the arm together with the blocking device 38 in the direction of the arrow 43 on the blade, an arrangement as shown in FIG. 9 is used, in which a sharp arm is provided. 44 which is formed by a party

and a bent portion 46.

  On the arm 45 is located a locking device 47 which holds the blade 7 with blocking and without possibility of collapse,

  an identical locking device 48 being mounted on the adjacent blade 7.

  Here again, the arm pivots about its axis of rotation 36 and this time two adjacent blades 7 pivot, and what is important is that the arm 46 serves as a spacer between the two blades, so that these

  the last ones do not come to apply one on the other.

  It is still important, when the vertical installation is bent, to ensure that the orientation cords 8 do not break since in the case of a curvature, an orientation cord 8 located on the outer portion of the curve is longer than at the level

  of an inner part of the curve. In order to avoid an excessive

  on orientation cords 8 in the case of vertical installations.

  bent shims, according to the invention, in the vicinity of each orientation cord 8, a compensation element 49, which is

  constituted, in a preferred embodiment, by a helicoidal spring

  dal 50. Each helical spring makes it possible, because of its elasticity, to obtain length compensation for the orientation cord 8, which makes it possible to avoid a rupture of the orientation cord 8

  in the case of vertical curved installations.

  It goes without saying that other embodiments of devices

orientation are possible.

  For example, the elongated arms 37 shown here can be omitted and corresponding arm-shaped orientation elements can also be provided integral in rotation with the last pusher 3 connected to the cords, these orientation elements being applied equally well. one side only on the other side of the blade in order to get a rotation

of this blade.

  In the case of the present invention, the only important point is that the last pusher connected to the cords cooperates with an orientation device, which pivots the pusher around its

  longitudinal axis (vertical axis) and that this rotation of the last

  connected to the cords is communicated via the cor-

  orientation of the blade, at all 1-blades.

  As was also mentioned above, the last push was

  connected to the cords can also be connected by being

* dary in rotation, corresponding arms, which apply on the pivoting sides of the last respective blade to guide this

  blade as well in one direction as in the other.
