METHOD FOR ADJUSTING AT LEAST ONE DIMENSION OF AN OCCULTATION DEVICE OF AN OPENING IN A BUILDING.

FR 3 060 047 - A1 (5 /) The invention relates to a method for adjusting at least one dimension, such as the length, of a device 1 for closing an opening in a frame. It finds an application to the adjustment of a rolling shutter to the width of the opening in the frame intended to be closed by the device.

The device 1 comprises a tube 2 on which is wound an apron 3, housed in a trunk 5, 6 having first and second ends and closed at at least its first end by a closing cheek 7, 8.

The method comprises a step during which the tube 2 and the apron 3 are brought into abutment against the cheek 7, 8 and held in this position in the trunk 5, 6, and a step during which the assembly comprising d on the one hand the tube 2 and the apron 3 abutting against the cheek 7, 8 in the trunk 5, 6, and on the other hand the trunk 5, 6, is cut in a single cutting operation according to a perpendicular cutting plane to the axis of the tube 2, so as to obtain the adjustment of the dimension of the device to the dimension of the opening.

Method for adjusting at least one dimension of a device for blocking an opening in a frame

The present invention relates to a method for adjusting at least one dimension of a device for closing, blocking or obscuring an opening in a frame. It finds an application to the adjustment of the width of a rolling shutter, such as a rolling shutter with louvered apron, of standard initial length, to the width of the opening in the frame intended to be closed by the device. closing.

In the present description, a closure device, a concealment device, and a device for obscuring by the expression concealment device will be denoted indifferently.

Blackout devices of the roller shutter type are very widespread, whether they are crank, strap or motorized devices. Such a device notably comprises a tube forming an axis, around which an apron is wound. Most often, the apron comprises a plurality of integral blades two by two. Each blade is thus connected to two other blades, with the exception of the initial blade which is connected directly to the tube by attachment means, and the final blade connected to a single other blade.

The tube and the apron are housed in a trunk, generally of substantially parallelepipedal overall shape. This chest is closed at its two lateral ends by closing cheeks, the tube being connected to at least one of the cheeks by a connecting end piece. At least one guide flange, also connected to one of the cheeks, for example by screwing, makes it possible to guide the winding and unwinding of the apron around the tube. The trunk is intended to be inserted at the top of an opening, between two side walls of this opening.

The maneuver is in principle arranged near one of the two ends of the trunk. This maneuver makes it possible to drive the tube in rotation in one direction or the other, in order to obtain the unwinding of the apron and thus the closure or concealment of the opening concerned, or the winding of this apron and thus the reopening .

During manufacturing, the various elements that make up the concealment device, including the walls of the trunk, the tube and the apron blades, are designed with specific dimensions. This is particularly the case for the length of the tube, the deck blades, and the walls of the trunk.

However, when installing the device at an opening in a frame, it may be necessary to adjust the dimensions of these elements of the concealment device to the precise configuration of the place where the opening is located. and the dimensions of the opening itself.

Thus, for example, during the installation of a roller shutter at a window, such as a window, in a house, if the window opening is made deep in a wall of the house, it is necessary to ensure that the trunk can be inserted between the two side walls of the opening. The length of the trunk must therefore theoretically be less than or equal to the width of the opening.

Furthermore, to ensure good concealment of the opening, the deck must have a sufficient width, theoretically substantially greater than or equal to the width of the opening.

These two constraints combined therefore lead to seeking to obtain a fitted device with a trunk of length substantially equal to the width of the opening, minus a certain installation margin.

Generally, the device is delivered unassembled or partially assembled to an installer. In the second case, for example, the device can be delivered pre-assembled without the operation. In this second case, the device is generally delivered with the assembly formed by the trunk closed by the closing cheeks and inside of which are arranged the apron wound on the tube connected to the cheeks by the end pieces and the flange (s). guide also connected to the cheeks, assembled.

After taking the measurements of the installation location, the installer cuts the tube, the deck blades and the walls of the trunk to the required length. If the device was delivered partially assembled as described above, the installer disassembles it and then cuts the tube, the deck blades and the walls of the boot.

This last configuration with the device delivered preassembled generally corresponds to the delivery of an adjustable standard device, intended for a non-professional installer.

The adjustment process is therefore relatively long and complicated, and each cutting action is a source of error. This is particularly the case when the installer is not a professional, and when he obtains the pre-assembled device or in a kit, for example in a large distribution area.

One of the aims of the invention is therefore to solve the aforementioned problems in particular. Thus, the object of the invention is in particular to propose a method for adjusting at least one dimension of the concealment device which is precise, quick and simple to implement.

A subject of the invention is thus, according to a first aspect, a method of adjusting at least one dimension, such as the length, of a device for concealing an opening in a frame, to a dimension, such as the width, of the opening.

The device comprises a tube on which an apron is wound, the tube and the apron being housed in a trunk having first and second ends and closed at at least its first end by a closing cheek.

The method comprises a first step during which the tube and the apron are brought into abutment against the cheek and held in this position in the trunk, and a second step during which the assembly comprising on the one hand the tube and the apron in abutment against the cheek in the trunk, and on the other hand the trunk, is cut in a single cutting operation according to a cutting plane perpendicular to the axis of the tube, so as to obtain the adjustment of the dimension of the device to the dimension of the opening.

According to certain modes of implementation, the method further comprises one or more of the following characteristics, taken alone or according to all technically possible combinations:

the tube is connected to the cheek by a connecting end piece, the device comprises at least one guide flange capable of guiding the winding and unwinding of the apron around the tube, and during the first step, the trunk is opened so as to access the end piece and the flange, the end piece and the flange are removed so as to bring the tube and the apron into abutment against the cheek, then the trunk is closed;

- The tube is connected to the cheek by a retractable type connecting end capable of retracting inside the tube, the device comprises at least one guide flange capable of guiding the winding and unwinding of the apron around the tube , and during the first step, we open the trunk so that we can access the flange, we remove this flange, we act on the end piece so that it retracts so as to bring the tube and the apron into abutment against the cheek, then we close the trunk;

- To act on the nozzle, a force is exerted on the tube along its axis in the direction of the cheek, and / or on the cheek along the axis of the tube in the direction of this tube, so that the end piece retracts inside the tube until the tube and the apron abuts against the cheek;

- during the first step, the device is placed so that the axis of the tube is in a horizontal position;

- during the first step, the device is placed so that the axis of the tube is in a vertical position with the cheek in the lowest position;

- the deck comprises a plurality of blades extending parallel to the axis of the tube, and during the second step, the plurality of blades is cut by the single cutting operation along the cutting plane;

- at the end of the second step, the distance between the cutting plane and one of the two ends of the trunk is substantially equal to the width of the opening intended to be obscured by the device, minus the thickness of the play and less installation margin.

- at the end of the second step, the distance between the cutting plane and the second end of the trunk is substantially equal to the width of the opening intended to be obscured by the device, minus the thickness of the cheek and less installation margin.

The invention also relates, according to a second aspect, to a method of installing a device for blocking an opening in a frame, the device comprising a tube on which an apron is wound, the tube and the apron. being housed in a trunk having first and second ends and closed at least at its first end by a closing cheek.

The method comprises measuring a dimension, such as the width, of the opening intended to be obscured by the device, and implementing the adjustment method as presented above, so that one of the dimensions of the device, such as its length, is adjusted the dimension of the opening.

In an implementation variant, after the single cutting operation, a maneuver able to put the tube in rotation around its axis is installed at the cut end of the tube, and the trunk is closed with the cheek at the end cut.

Thus, the adjustment method of the invention allows the adjustment, in particular of the length, of a concealment device such as a rolling shutter to a dimension, in particular the width, of the opening intended to be fitted. of the concealment device, in a limited number of steps, in a simple, rapid and precise manner.

The characteristics and advantages of the invention will appear on reading the description which follows, given only by way of example, and not limiting, with reference to the following appended figures:

- Figures 1A, 1B: schematic and partial representations, in exploded view, of two examples of occultation device 1 intended to be adjusted by the adjustment method according to the invention;

- Figure 2: simplified schematic representation of a blocking device 1 and an opening 10 in a frame intended to receive the installation of the device 1;

- Figure 3: schematic representation of the occulting device 1 of Figure 1A or 1B, in the adjustment configuration by the method according to the invention.

FIGS. 1A and 1B show in exploded view a part of the elements forming a device 1 for concealing the roller shutter type 1, in two exemplary embodiments.

This roller shutter 1 comprises a tube 2 around which a deck 3 with blades 4 is wound and unwound. Hooking means 12, 13 are provided for hanging the first of the blades 4 on the tube 2.

The winding and unwinding of the apron around the tube 2 is obtained by the rotational driving of this tube 2 around its central axis in one direction or the other. This rotary drive of the tube 2 is itself obtained by a maneuver not shown in FIG. 1, for example a strap maneuver, a crank maneuver or a motorized maneuver. This maneuver is generally connected to the tube 2 at one or the other of its ends.

The tube 2 and the deck 3 are housed in a trunk 5, 6 of substantially or approximately parallelepipedal overall shape. In the example shown in Figure 1, the trunk is formed of an upper part 5 forming the upper wall and the rear wall of the trunk, and of a lower part 6 forming the lower wall and the front wall of the trunk.

The trunk 5, 6 is closed at its two opposite ends by closing cheeks 7, 8. The tube is linked to each of the cheeks 7, 8 by its two respective ends, by means of a connecting end piece 9.

The example shown in FIG. 1A corresponds to a partial representation of a rolling shutter 1 with a strap, that is to say the operation of which comprises a strap which is wound around a pulley 20 which is itself connected to the tube 2 so as to allow the tube 2 to be driven. In this example, the end piece 9 and the pulley 20 form a single piece 9, 20, and the two ends of the tube 2 are each connected to one of the two cheeks 7, 8 by the assembly 9, 20 which also serves as a pulley, so that the maneuver can be mounted on the right or on the left.

In this example, the pulley 20 acts as a guide flange, which ensures the winding and correct unwinding of the deck 3 around the tube 2, in particular which prevents the blades 4 from shifting.

The example shown in FIG. 1B corresponds to a partial representation of a motorized rolling shutter 1, that is to say the operation of which comprises a tubular motor which is inserted into the tube 2 and which allows it to be driven. In this example, the end piece 9 at at least one of the ends of the trunk 5, 6 constitutes both a support for the tubular motor and a means for connecting the tube 2 to one of the cheeks 7, 8. In this In this case, it is necessary to use a separate guide flange 20 to perform the function described above.

Generally, the installer receives the roller shutter 1 such as that partially shown in Figures 1A and 1B, with the components shown in these preassembled figures, all in appropriate packaging.

This roller shutter 1, as a concealing or closing device 1, is therefore intended to be installed to conceal or close an opening in a frame, such as the opening 10 fitted with a window 11, shown in FIG. 2.

The roller shutter is shown very diagrammatically in FIG. 2, next to the opening 10, in position with the deck not unwound. Thus, only the trunk 5, 6 is shown for simplicity.

When the dimensions of the roller shutter 1 are standard, they are not necessarily adjusted to the dimensions of the opening 10 into which the roller shutter 1 must be inserted.

In particular, the overall length Lg of the roller shutter 1 can be greater than the width La of the opening in which this roller shutter is to be inserted or fitted.

To adjust this length Lg, the roller shutter is brought into the position such as that shown diagrammatically in FIG. 3.

Specifically, the apron 3 wound on the tube 2, and the tube 2 itself, are brought by one of their respective ends in abutment against one of the cheeks 7, 8, here the cheek 7, preferably on the side where an adjustment cut will be made, and preferably on the side where the maneuver will be installed later.

Beforehand, in the case of a rolling shutter 1, the tube 2 of which is connected to the cheek 7 by an end piece such as the assembly 9, 20 the part 20 of which also acts as a pulley, represented in FIG. 1A, this is first removed to allow the effective abutment of the end of the tube 2, and therefore also of the apron 3, against the inside of the cheek 7. To do this, the trunk is opened to access the end piece 9, and therefore to the pulley 20 which acts as a flange 20, and remove it, then the trunk is closed as shown in FIG. 3. We can for example simply remove the cheek 7 to access the assembly 9, 20 then reposition the cheek 7. Optionally, it may also be necessary to open the trunk 5, 6 by separating the walls 5 and 6 from one another, before resolidating them.

Alternatively, in the case where the tube 2 of the roller shutter 1 is connected to the cheek 7 by a tip of retractable type, intended for example for pre-assembly and which can then be replaced by a specific tip adapted to the type of operation, in particular in the in the case of a winch type maneuver, it is not necessary to remove the end piece beforehand, but to retract it completely, so as to allow this effective abutment of the end of the tube 2, and therefore also of the apron 3, against the inside of the cheek 7.

In this case, as shown in FIG. 1B, the device 1 is provided with a guide flange 20 also connected to the cheek 7, for example by screwing. Also, even if it is not necessary to access the retractable end piece 9 and remove the latter, it remains necessary to access this flange 20 to remove it.

In this case, once the flange 20 has been removed, it is necessary to be able to act on the retractable end piece. By retractable tip is meant a tip which can be moved between a fully retracted position inside the tube 2 without it protruding outside of this tube 2, is a position in which it extends to the outside of tube 2 over a maximum length. This can for example be obtained by means of a tube 2, the end of which is pierced with a few holes aligned parallel to the axis of the tube over a certain distance, each capable of cooperating with a lug or a spring button, which protrudes of the outer wall of the endpiece 9 in the rest position and which can be pressed into this wall by pressure so as to no longer or almost no longer protrude from this wall.

The retraction means, such as the hole / button cooperation presented in the preceding paragraph, can be such that the retraction of the end piece in the tube 2 can be obtained by exerting a force on the tube 2 along its central axis in the direction of the end provided with the end piece, and by preventing the end piece from moving in this same direction, or by exerting a force on the cheek 7 (having previously removed the walls 5, 6 of the trunk) along the central axis of the tube 2 in the direction of this tube 2, or by combining the exercise of the two types of force.

Thus, one can for example place the entire rolling shutter so that the axis of the tube (2) is in a horizontal position to act on the retractable end piece as explained above. Alternatively, it is also possible to place the entire rolling shutter so that the axis of the tube (2) is in the vertical position, with the cheek 7 in the low position, as in the variant without retractable tip shown in FIG. 3. in this case, the retractable tip being blocked in the low position against the cheek 7, it may suffice to exert pressure on the tube 2 along its axis in the direction of the cheek, after having unlocked the retraction means mentioned above if these do not unlock automatically.

Once the tube 2 and the deck 3, therefore also the blades 4 of the deck 3 in the example shown in the figures, in abutment against the cheek 7, the installer proceeds to a single cutting operation according to a cutting plane ( C) perpendicular to the axis of the tube 2, as shown in FIG. 3.

Specifically, this single cutting operation makes it possible to cut to the desired length La, and in one go, the tube 2 along the cutting line 19, the deck 3, and its blades (in the case of a deck with blades 4 as shown in Figure 1), along the cutting line 18, as well as the trunk 5, 6 along the cutting lines 14, 15, 16, 17 (in the example shown, the wall 5 along the cutting lines 14, 15 and the wall 6 along the cutting lines 16, 17).

One can provide, for the needs of the installation at the opening 10 shown in FIG. 2, an installation margin, in principle of a few millimeters, for example 5 mm, so that the distance between the plane of cut (C) and one of the two ends of the trunk 5, 6, therefore the new length of the trunk 5, 6 cut, is substantially equal to the width La of the opening 10, minus the thickness of a cheek 7 , 8 and less the installation margin.

In the example shown in Figure 3, the cut is made so that the distance between the cutting plane (C) and the second end of the trunk 5, 6, so the end opposite to the end in which the tube 2 and the apron 3 abuts against the cheek 7, ie substantially equal to the width La of the opening 10, less the thickness of the cheek 7 and less the installation margin.

Thus, the installer can proceed with the installation of the device 1 by first taking the appropriate measures on the opening 10, in particular the measurement of the width La of this opening 10, then by implementing the method of adjustment by the single cutting operation as described above. Once the length of the device 1 has been adjusted to the width La of the opening 10 as described above, the maneuver can be installed, preferably at the cut end of the tube 2. To do this, the cheek 7 is removed, the maneuver is put in place, and the cheek 7 is replaced to close the trunk 5, 6. If necessary, if the withdrawal of the cheek 7 does not provide sufficient access for the implementation of the maneuver, the trunk 5, 6 can be opened by separating the walls 5 and 6 before resolidating them.

The installation can then be continued in a conventional manner and known per se (in particular installation of any other elements of the device 1, installation of the assembly in the location provided at the opening 10).

This description is given by way of example and is not limitative of the invention.

In particular, the invention is not limited to the adjustment and installation of a device of the rolling shutter type with louvered deck, nor to the adjustment and installation of a device of strictly parallelepiped shape.
