Description

2. SECTOR OF THE TECHNIQUE:

According to the International Patent Classification CIP 2007 this invention is included in group E: Fixed constructions- Category E06: Doors, windows, shutters or folding metal curtains in general, Subcategory E06B Fixed or mobile closures for the opening of buildings.

3. STATE OF THE ART:

There are different devices for closing facade openings, being the most effective ones that are installed outside, intercepting solar radiation before it passes through the glass and penetrates inside the building, improving the energetic efficiency.

The situation outside difficult the design of the shutters especially because of the wind which requires to pay attention to the bindings.

There are shutters that are located inside an air chamber between the two panes of windows with double glazing, an intermediate solution that allows to install shutters of blades like those which are used for the interior because they are not not exposed, but whose protection is reduced compared to those which are completely external, because the air chamber of the double glazing heats up.

Fixed blade closures, even if the inclination of the blades can be varied to allow passage of air and light, always interrupt vision from the outside.

Blade shutters known as "Venetians" or "Mallorquins" carry the blades attached to a frame, like another window sill on the outside. You need another frame to fix the hinges and be able to take it on the facade to completely release the opening of the window, which sometimes is not possible. The maintenance of the outer part becomes complicated. Permanent exposure to the weather means that maintenance must be frequent.

Some shutters fold upwards, like visors, without being able to remove them completely, limiting the view of the sky through the window.

The traditional shutters are gathered together, wrapping themselves on a drum located on the window in a box built in the facade. The blades move by vertical guides next to the window. The blades are taken to each other in all its length so that when the drum turns they train and go up, and going down they lean on one another by nesting. As they are united in all its length, they can not be oriented or cleaned by the outside. The blades have a limited width to adapt to the surface of the drum, and the dimensions of the front opening are also limited by the bending of the blades, which are very inflexible. For some dimensions it is necessary to motorize them to overcome the weight of the blades.

A rollable blind model of steerable blades has been marketed which allows the blades to tilt when the blind is fully lowered, but not in another position, and with a limited inclination angle. The winding determines the shape of the blade with the disadvantages mentioned for them.

The mentioned drawbacks of existing mechanisms are avoided with the mechanism presented here.

4. EXPLANATION OF THE INVENTION:

This invention model 200800913U is a mechanism for the securing and actuation of shutters of blades to put in the openings of facade (windows, doors, showcases), able to place it outside by improving the protection against bad weather, especially against solar radiation. The attachment of the blades is secure enough to install outdoors, with a device that allows to use all kinds of blades, rotate them in all degrees of inclination until they touch, and remove them partially or completely from the facade opening, completely clearing the vision from the outside.

The model 200802282U is an improvement of the model 200800913U to obtain a better closure of adjustable blades, stackable on one side or the other of the opening of facade, and security. This increases the utility of the invention. It is not necessary to build a box in front as with traditional shutters. The fact that one can pick up the blades at the top or bottom of a window allows, in addition to graduating the entrance of the solar radiation, to protect from the external vision allowing light to pass through the upper part. It increases the security of the closure, so it is appropriate to install it on the ground floor.

These characteristics are obtained by means of the form of securing the blade parts to the side screws, the modification of the worms to improve the packing of the blades out of the front opening, and with a new form of actuation of the inclination of the blades.

As described later in model 200800913U, the actuating and securing mechanism of the swiveling and removable leaf flaps consists of two worms side, on each side of the facade opening, where one hangs the ends of the blades. By rotating the screws without rotating the devices that catch the blades, they slide through the screws, like a corkscrew. The screws on both sides of the synchronously shaped window are rotated manually with a crank and a transmission mechanism, or motor-driven, so that the clashes of the blades on both sides slide simultaneously, so that the blades run parallel while closing. completely or partially, or by completely releasing the opening.

To improve the packing system is made the attachment device of the blade so that it can reduce the pitch of the screws at the ends without interrupting the movement. The pitch determines the distance between the blades. By decreasing it at the end of the worm, the separation between the blades decreases, allowing its storage in very little space.

In the endless screws, the central span, which coincides with the space of the facade opening, has the thread of the measurement of the width of the blade minus the width of the part of contact between them. At the ends, the worm has a span with a screw pitch measuring the thickness of the blade plus an ease, which determines the minimum space of heaping.

The devices for attaching the blades are nuts that are threaded into the endless screws, ensuring the union with these and also the safety of the assembly. The threading of the nuts to the screws is by means of bearings to allow the continuity of the translational movement despite the change of the thread.

The mechanism of inclination of the blades is interposed between the blades and the nuts for attachment to the screws. It is a piece that grasps the end of the blade and joins it to the nuts, and a rack parallel to the screws between the screws and the blades. The end piece of the blade consists of an elongated part where the blade fits together, joined to a pin with a pinion, hooked to the nut, so that it can turn and transmit this movement to the blade.

The rack is placed laterally, all along the side of the window, in contact with the gables of the parts of the end of the blades. It can turn freely unless it is immobilized. When we go up and down the blades they drag it if it is released.

In order to turn the blades, the rack pressing is put on it by a control of the interior of the building, and by actuating the screws to move the blades, the pinions roll on the rack by tilting the blades.

Model Description 200800913U.

The mechanism consists of two worm screws, one on each side of the opening of the facade, to which cling the ends of the blades. The worms have a helical rail, and by rotating the screws and preventing rotation of the shackles of the blades, it transmits to them a translation movement parallel to the longitudinal axis.

The rotation of the screws is actuated simultaneously, manually with a crank or motorized, of synchronized shape so that the translation movement produced parallel to the direction of its axis is the same. This is possible by rotating the screws on its axis by means of a horizontal bar with gears at the ends, which transmit rotation to the base of the worms. It can also be done with a belt or a chain of transmission which makes turn simultaneously the bases of the augers. A locking device prevents the blades from falling by gravity.

As all the devices of attachment of the blades are in orthogonal position to the same generatrix of the cylinder surrounding the helix, they move at the same distance between them: a distance multiple of the pitch of screw. This distance must measure the width of the blade minus the width of the contact surface between them. In the fully open position, that is by removing the blades, we obtain that they occupy a minimum of space by reducing the distance between them as described later.

As the blades are gripped by the end screws, by fixing the screws to the front the blades resist the wind pressure, which allows installation outside. This also causes the blades and their snaps to be pulled, so that longer blades can be used without flexing, for use in large facade openings. By firmly attaching the worm gear to the front and using sufficiently strong blades, you also get a security flap against theft that can be removed completely when it is not needed.

The permanent contact between the blades and the worm also allows the installation of a conductive wire to transmit solar energy collected by cells in the blades to the electrical network inside the building.

This mechanism allows to insert in the fastenings of the blades several kinds of mechanisms for actuating the rotation of the blades, as well as to rotate them in any position, controlling the opening and yet the admission of light and ventilation . Blades can be collected in any side of the facade opening, up or down. If the blades are vertical and the augers are horizontal the blades can be collected in the sides. With the worms in an inclined position it is possible to cover Inclined facade openings, and installed on structures, they can be used as blankets of weather, for example, porches or terraces.

• Dans le cas de l'adoption de la forme de vis sans fin par un rail en spirale autour d'une tige centrale, et dans le cas de la formation d'une fente hélicoïdale à l'intérieur d'un cylindre solide, le dispositif d'accrochement est un roulement cylindrique qui roule par la spirale, unie à une barre et tournant indépendamment d'elle. La barre connecte avec l'extrémité de la lame.
• Dans le cas de formation de la vis avec une plaque hélicoïdale unie à une tige centrale pour agir comme un filet d'écrou, le dispositif d'accrochage de la lame est une pièce cylindrique creuse avec une fente dans sa surface intérieure pour se visser. La pièce cylindrique glisse en vertical sans tourner. Elle s'unit à la lame au moyen d'une barre qui s'insère dans la pièce pouvant tourner sur son axe longitudinal. On peut aussi accrocher les lames aux écrous au moyen d'un câble enroulé à la pièce et relié à la lame, tendu.

The attachment of the blades to the worm is done by means of devices that slide by the worm pushed by the spiral. According to the different shapes of the spiral, the devices for attaching the blades can be:

• In the case of adopting the form of worm by a spiral rail around a central rod, and in the case of the formation of a helical slot inside a solid cylinder, the device is a cylindrical bearing that rolls through the spiral, united to a bar and rotating independently of it. The bar connects with the end of the blade.
• In the case of forming the screw with a helical plate united to a central rod to act as a nut thread, the blade attachment device is a hollow cylindrical piece with a slot in its inner surface for screwing. The cylindrical piece slides vertically without turning. It is joined to the blade by means of a bar which fits into the part which can rotate on its longitudinal axis. The blades can also be attached to the nuts by means of a cable wound to the workpiece and connected to the blade, stretched.

The stacking of the blades can be done at the top or bottom of the opening of facade, or in the lateral ones. If sliding by the worm is by means of a bearing, the blades are collected by reducing the pitch of the screw until it is equal to the thickness of the blade plus a margin. It is also possible by removing the propeller at the end of the course; leaving the hanging devices of the blades piled up. In the case of using the hollow cylindrical part with the helical slot inside, the packing of the blades is done with a smooth span at the upper end of the worm, where the shackles will remain packed. They are unscrewed by the movement of the screw, and insert again into the screw by gravity or assisted by a spring, when the screw and the slot coincide.

1. a.- Dans la barre d'union entre le dispositif d'accrochage et la lame, se trouve un pignon activé par une crémaillère qui le fait rouler quand elle est pressionnée et que l'on fait monter ou baisser pour faire tourner les lames. La crémaillère est placée sur une plaque verticale que l'on pressionne ou pas contre les roulements.
2. b.- Dans les barres de transmission de la rotation des vis on place une articulation qui pousse ou retire les extrémités des barres. Quand elles sont élongées elles engrainent avec les bases des vis sans fin et produisent le mouvement de montée et descente des lames. Quand elles sont dans la position la plus courte, elles engrainent avec une crémaillère verticale, la soulevant ou l'abaissant, en faisant tourner les lames.
3. c.- Aux extrémités des lames on introduit une baguette engainée qui peut entrer plus ou moins dans la gaine, laissant une extrémité dehors. Cette extrémité peut être fixé et, en actionnant le déplacement des lames celles ci s'inclinent. En la libérant, elles se déplacent.
4. d.- Dans le cas ou les lames son prises par des câbles on intercale un dispositif pour rapprocher les câbles juste en dehors du dispositif d'accrochement. Les câbles vont tout le long de la lame, parallèles avec cette même distance entre eux. La pièce qui les rassemble est un pignon que l'on peu faire tourner, en faisant tourner la position des câbles et pourtant, aussi les lames.
5. e.-La rotation des lames peut se produire par un système de câbles fixés à ses angles et tirant d'un côté ou de l'autre, de l'extérieur ou de l'intérieur, de la même façon que l'on fait avec les rideaux de lames installés à l'intérieur des bâtiments. La traction des lames se fait du côté opposé au ramassage des lames, où les câbles ne sont pas tendus.

The mechanism for orienting the blades can be on the blade or between the blade and the worm, in the connection bar of the blade to the shackles. The blade can be rotated by itself, or one side of the blade can be immobilized while the other is moved by the movement of the worm. Several ways of operation are then described.

1. a.- In the tie bar between the shackle and the blade, there is a pinion activated by a rack which makes it roll when it is pressed and is raised or lowered to rotate the blades. The rack is placed on a vertical plate that is pressed against the bearings or not.
2. b.- In the bars of transmission of the rotation of the screws is placed a joint which pushes or withdraws the extremities of the bars. When they are elongated they engrain with the bases of the worm and produce the movement of rise and descent of the blades. When they are in the shortest position, they engrain with a vertical rack, lifting or lowering it, rotating the blades.
3. c.- At the ends of the blades is introduced a sheathed rod that can enter more or less in the sheath, leaving an end outside. This end can be fixed and, by actuating the movement of the blades, they are inclined. By releasing it, they move.
4. d.- In the case where the blades are taken by cables is interposed a device to bring the cables just outside the hooking device. The cables go all along the blade, parallel with the same distance between them. The piece that brings them together is a pinion that can be rotated, rotating the position of the cables and yet, also the blades.
5. e.-The rotation of the blades can occur by a system of cables fixed at its corners and pulling from one side or the other, from the outside or the inside, in the same way as one does with the curtains of blades installed inside the buildings. The traction of the blades is on the opposite side to the gathering of the blades, where the cables are not stretched.

The blades are gripped to the attachment device by a bar or by means of cables, as already described. The bar can take the blade by means of a rectangular piece by introducing into its interior the end of the blade. It can be fixed by pressure, adhere, or nail. If the hooking is by cables, they are sheathed all along the blade, from one worm to the other. Stretching the cables avoids the bending of the blade.

The blades can be made of different materials, wood, metal, plastic, in all cases prepared for the outdoors. The blades can be trac- tioned since they are grasped by the ends to the side screws, which allows longer blades to be used for larger facade openings.

By using sufficiently strong blades (for example curved steel plates), or continuing along the length of the blade bar, from one endless screw to the other, made of steel, one obtains a security lock against theft, such as a removable fence.

With solar cells placed on the blades, electrical energy can be transmitted to the side worms. Inside these one connects with the electrical network of the interior of the building. Solar energy capture can be optimized by using sensors to orient the blades perpendicular to the rays.

All parts described as metallic may be made of other materials, such as nylon or wood.

The simplicity of the installation and its operation makes it possible to deliver it by pieces to be assembled by the users.

Model Description 200802282U.

The mechanism consists of the following elements: two worm screws (1), one on each side of the façade opening, with one or more spirals, which have at one or both ends a span with the reduced thread relative to the thread of the central span; fastening devices (3) for the blades which are threaded to the worm by means of bearings (4); a support piece for the blade (5) which unites it to the attachment device (3), provided with a pinion (6) to actuate the inclination of the blade; a rack (7) which travels the distance from the side of the facade opening and contacts with the pinions (6) parts (5) of the blade support which are in the span of the front opening; a brake device (8) of the rack (7) for actuating the inclination of the blades preventing its translation, rolling the pinions (6) when the worm (1) is rotated with the rack (7) braked ; a carcass (9) enclosing the assembly to protect it, with fasteners to the facade, and with a vertical slot or guide (10) by which the blades connect with the mechanism located inside.

1. a) Le mouvement vertical des lames:
   • Les lames sont saisies par deux vis sans fin (1) situées aux côtés de l'ouverture de façade à couvrir. Elles se prennent au moyen des dispositifs d'accrochage (3) qui sont des écrous qui s'appuient dans les spirales des vis sans fin au moyen de roulements (4).En faisant tourner les vis sans fin (1) tout en empêchant de tourner les dispositifs d'accrochage (3) celles-ci se déplacent le long des vis sans fin (1) poussées par les roulements (4). On empêche de tourner les dispositifs d'accrochage (3) au moyen d'une guide (10).
   • La rotation des vis sans fin (1) s'actionne simultanément, manuellement avec une manivelle ou bien motorisée, synchronisées pour que le mouvement de translation vertical soit le même. Au moyen d'un dispositif on encloue les vis sans fin en empêchant les lames de tomber par gravité.
   • Les lames sont saisies aux dispositifs d'accrochage (3) par l'intermédiaire d'une pièce (5) qui les supporte. Les lames se déplacent en maintenant entre elles la même distance. Cette distance est un multiple du pas de la vis sans fin (1). Elle doit mesurer la largeur de la lame moins la largeur de la surface de contact entre elles quand elles sont fermées, de façon que l'ouverture de façade soit complètement couverte quand les lames se touchent.
2. b) Le ramassage des lames hors de l'ouverture de façade:
   • Les vis sans fin (1) latérales ont à leurs extrémités des travées avec un pas de vis plus petit (2) que celui de la travée centrale correspondant à l'ouverture de façade. Les dispositifs d'accrochage (3) s'enfilent dans les vis sans fin au moyen de roulements (4), pour permettre la continuité du mouvement de translation dans la variation du pas de vis. Quand les dispositifs d'accrochage (3) arrivent dans les travées (2) des extrémités, la distance entre eux diminue, en entassant les lames dans peu d'espace hors de l'ouverture de façade. La distance entre eux est égale à l'épaisseur de la lame plus une aisance.
3. c) L'orientation des lames:
   • Le pignon (6) de la pièce (5) de support de la lame est en contact avec la crémaillère (7) et l'entraîne dans son mouvement de translation. En immobilisant la crémaillère au moyen d'un frein (8), le pignon (6) roule sur la crémaillère quand on actionne le mouvement de translation, en faisant tourner la lame. La crémaillère (7) contacte seulement avec les pignons qui se trouvent dans la travée centrale qui correspond à l'ouverture de façade, elle n'agit pas sur celles qui sont ramassées dans la travée avec le pas de vis diminué.

The operation is as follows:

1. a) The vertical movement of the blades:
   • The blades are gripped by two worm screws (1) located at the sides of the front opening to be covered. They are taken by means of the fastening devices (3) which are nuts which are supported in the spirals of the worms by means of bearings (4). By rotating the worm (1) while preventing turn the latching devices (3) these move along the worm (1) pushed by the bearings (4). The latches (3) are prevented from rotating by means of a guide (10).
   • The rotation of the worm (1) is operated simultaneously, manually with a crank or motorized, synchronized so that the vertical translation movement is the same. By means of a device the worm is inserted by preventing the blades from falling by gravity.
   • The blades are gripped to the attachment devices (3) via a part (5) which supports them. The blades move while maintaining the same distance between them. This distance is a multiple of the pitch of the worm (1). It must measure the width of the blade minus the width the contact surface between them when they are closed, so that the front opening is completely covered when the blades touch each other.
2. b) The collection of the blades out of the facade opening:
   • The endless screws (1) have at their ends spans with a smaller screw pitch (2) than that of the central span corresponding to the front opening. The attachment devices (3) are threaded into the worm by means of bearings (4), to allow the continuity of the translational movement in the variation of the thread. When the hooking devices (3) arrive in the spans (2) of the ends, the distance between them decreases, piling the blades in little space outside the opening facade. The distance between them is equal to the thickness of the blade plus an ease.
3. c) The orientation of the blades:
   • The pinion (6) of the piece (5) for supporting the blade is in contact with the rack (7) and drives in its translational movement. By immobilizing the rack with a brake (8), the pinion (6) rolls on the rack when actuating the translational movement, rotating the blade. The rack (7) contacts only with the gears that are in the central span that corresponds to the front opening, it does not act on those that are collected in the bay with the screw pitch decreased.

In the last eight pages of figures (FIGS. 5 to 59) are shown the four operating examples A, B, C and D of the Model 200800913U, which comprise the components of the invention. The images of the set and the details of the larger pieces are represented. To distinguish the numbering of parts from these examples from Model 200802282U coin counts, the numbers are not in parentheses.

6. EXAMPLES OF CARRYING OUT THE INVENTION:

As an application of the foregoing five operating models are described: the first corresponds to the Model 200802282U, already described in detail. The following four correspond to Examples A, B, C, and D of Model 200800913U, which is described below. These models are examples of implementation of the invention.

EXAMPLE A

1. 1.-The endless screws which turn produce the translation movement parallel to the longitudinal axis are constituted by a helical channel U with a central shaft 1 which is housed a bearing 8.
2. 2.-The manual or motorized mechanism transmits the rotational movement to the lateral spirals around its longitudinal axis by a bar.
3. 3.-The fixings of the blades to the propellers are cylindrical bearings. The bearing 8 is united at the end of a rod 7, which is fixed to the end of the blade. The rod 7 has a grooved bay or pinion 19 to actuate the rotation of the blades.
4. 4.-To prevent the movement of the bearings 8 out of the line of motion parallel to the axis of the spiral, the bars 7 are held in position through the slot of a fixed cylinder 14 which surrounds the propeller 1 Ce cylinder also protects the propeller and bearings.
5. 5.-The mechanism of rotation of the blades: Between the cylinder 14 and the space occupied by the blades is placed a rack 20 which by pressing against the pinion 19 of the bar 7 rotates. By means of a pinion 24 installed in the drive transmission bar of the worm 1, a vertical movement of the rack 20 is produced which rotates the pinion 19 of the bar 7 and thus the inclination of blades. The pinion 24 moves pushed by a mechanism 21 located in the transmission rod composed of rods 26 driven by a central axis 25.
6. 6.-The blade storage device out of the front opening: At the ends of the worm 1, out of the span that covers the front opening, propellers have been modified to reduce the screw pitch 4, which brings together the blades occupying little space.

EXAMPLE B

1. 1.-The augers which turn to produce the translation movement parallel to the longitudinal axis are constituted by a solid cylinder with a helical groove 2 widened on the inside, where the bearings are placed. 8.
2. 2.- The manual or motorized mechanism transmits the rotational movement to the lateral spirals around its longitudinal axis by a bar as in the model A.
3. 3.-The fasteners of the blades to the worm are the bearings 8 housed in the helical groove of the cylinder 2, united to the bars 7.
4. 4 .- To prevent the movement of the fasteners of the blades 8 out of the line of motion parallel to the axis of the spiral, the bar 7 which unites the end of the blade falls on the vertical plate 15 which prevents them from descending by the rail.
5. 5.-The rotation of the blades is produced by a tilting rack 20 as in the model A, which is fixed by means of two parallel axes 21 to a fixed plate 22. By actuating a lever 23 vertically, one touches or releases the pinions 19. In the rest position the gables must be held to maintain the inclination of the blades. Once released, the blades can move in the direction of the axis of the screw. The shape of the pinion 19 may be a span of the same bar 7 with the striated surface.
6. 6.-The storage device of the blades out of the opening of facade: At the upper end of the propeller has a straight rail 5, in which the bearings 8 are pushed by the movement of the screw 2 when they arrive at the top. The blades are thus collected in a compartment 5 outside the front opening. By gravity the bearings 8 will be taken up in the propellers when they rotate in the downward direction.

EXAMPLE C

1. 1.-The endless screws which turn produce the translational movement parallel to its longitudinal axis, are formed by a helical thread fixed around a central shaft 3 to be inserted as a tongue in a slot 11 in the fasteners of the blades 9.
2. 2.-The manual or motorized mechanism transmits the rotational movement to the lateral spirals around its longitudinal axis by a bar as in models A and B, or by a chain, or by a belt.
3. 3.-The fasteners of the blades to the worm are nuts 9 by the inside of which passes the screw 3. In the inner slot of the nut is inserted the tongue of the screw 3. by turning the screws and preventing rotation of the nuts, the translational movement of the bar 7 and the bearing 8 located inside the nut 9, occurs similar in shape to the models A and B. The union of the blade to the Nut can also be done by cables wound to the nut by its outside and taken to the blade with traction. The cables are gathered in a pinion before being fixed to the blades.
4. 4.-The device that prevents the movement of the fixings of the blades out of the line of motion parallel to the axis of the spiral is the same part 9, because it has confined to its interior the bearing 8.
5. 5.-The rotation mechanisms of the blades can be like those of the models A and B, by means of the parts 19 and 20, in the case of use of the bar 7 and the bearing 8, also in the case of fixing by cables, by rotating the cylindrical part that traps the cables.
6. 6.-The blade storage device out of the facade opening: at the upper end of the screw there is a smooth span without spiral 6, where the blades fixing devices. By gravity they will enter the propeller when the screws turn in the direction of the descent. If the stacking is not vertical, we will add a spring to recover the position.

EXAMPLE D

The worm 3, and the blade storage device out of the front opening 6 are as in the model C. What changes is the way to actuate the rotation of the blades.

The nuts 10 for fixing the blades are similar to the part 9 of the model C. They are differentiated by a horizontal striated surface 12 which support the securing bearings 13 of the blades. They roll on this surface 12, transmitting the rotation by means of the rod 7.

The device which prevents the displacement of the securing bearings 13 of the blades from the line of the translation movement parallel to the axis of the spiral 3 is a plate longitudinal 16 which is inserted into the notches 18 made in the outer surface of the nuts 10. This same device 16, 18, actuates the rotation of the blades, by moving the longitudinal plate 16 in a circular motion about the axis of the propeller 3 by rotating the nuts 10 and then the bearing 13 on the horizontal serrated surface 12 by rotating the bar 7 and thus the blade.

Mécanisme d'assujettissement et d'actionnement de fermetures de lames orientables et retirables, qui se caractérise pour avoir un opérateur de translation des lames formé par deux vis sans fin parallèles 1, 2, 3, auxquelles sont assujettis les extrémités des lames et qui tournent de forme synchronisée autour de leurs axes respectifs. Les formes des vis peuvent être: soit un rail hélicoïdal en U fixé à un arbre central 1, soit une rainure hélicoïdale en fente dans un cylindre 2, soit un filet hélicoïdal fixé à un arbre central 3, ou bien d'autres formes.
2. 2. Mécanisme d'assujettissement et d'actionnement de fermetures de lames orientables et retirables, comme la revendication précédente, qui se caractérise par le fait de faire l'entassement 4, 5, 6, des lames hors de l'ouverture de façade en diminuant la distance entre elles pour occuper le moins d'espace possible lorsqu'on les ramasse. On peu le faire en réduisant le pas de vis 4, en finissant l'hélice dans un rail droit où s'introduisent les supports des lames 5, en finissant la vis avec une travée lisse sans hélice 6, en empilant les écrous 9, 10, ou par d'autres formes.
3. 3. Mécanisme d'assujettissement et d'actionnement de fermetures de lames orientables et retirables, comme la revendication précédente, qui se caractérise par le fait d'avoir des dispositifs d'accrochement des lames 7, 8, 9, 10, aux vis sans fin. Ces dispositifs n'empêchent pas de faire tourner la lame sur son axe longitudinal, et ils permettent le mouvement de translation des lames au long des vis. Ces mécanismes peuvent être formés par des barres 7 fixées aux lames en prolongation d'elles, avec un roulement 8 à son extrémité qui se saisi à la spirale de la vis; ou bien des écrous 9 auxquels s'enroulent les vis 3 et qui prennent les barres 7 fixées aux lames; ou des écrous avec une surface horizontale striée où s'appuient les roulements 13 fixés au barres 7 qui supportent les lames, ou par d'autres formes.
4. 4. Mécanisme d'assujettissement et d'actionnement de fermetures de lames orientables et retirables, comme la revendication précédente, caractérisé par la production de mouvement au long des vis au moyen des dispositifs 14, 15, 16, en empêchant de faire tourner les dispositifs d'assujettissement des lames 7, 8, 9, autour des axes des vis. Ces dispositifs peuvent être formés par un tube cylindrique 14 avec une rainure longitudinale 17 qui oblige les barres 7 à s'y déplacer; une plaque verticale fixe 15 qui empêche le barres de descendre en tournant par l'hélice de la vis 3; une plaque verticale 16 qui s'insère dans les encoches 18 faites dans la surface extérieure des écrous 10 en fixant sa position, ou bien par d'autres formes.
5. 5. Mécanisme de rotation des lames sur leur axe longitudinal au moyen d' un pignon 19, situé dans les barres d'assujettissement 7 des lames, et avec le même axe longitudinal. On déclenche la rotation par un mécanisme comprenant une crémaillère basculante 20, qui est prise par deux axes parallèles 21 à une plaque fixe 22 à actionner en mouvement vertical par un levier 23, en pressionnant ou en libérant les pignons 19. Dans la position de repos les pignons doivent être saisis pour maintenir l'inclination des lames. Une fois libérées, les lames peuvent se déplacer dans la direction de l'axe de la vis. La forme du pignon 19 peut être une travée de la même barre 7 avec la surface striée. La crémaillère 20 peut également être actionnée par un mécanisme comprenant un pignon 24 à deux positions, déplacé de la crémaillère ou face à elle, le déplacement d'une position à l'autre se fait au moyen d'un axe central 25 qui en tournant pousse des tiges 26 qu'on a fixé aux extrémités des pignons. 24.

The following text describes in more detail the components of the invention:

1. 1. Mechanism for securing and actuating adjustable and removable blade closures, which is characterized to have a blade translation operator formed by two parallel worms 1, 2, 3, which are subject to the ends of the blades and which rotate synchronously around their respective axes. The shapes of the screws may be: either a U-shaped helical rail attached to a central shaft 1, or a helical slot groove in a cylinder 2, or a helical thread fixed to a central shaft 3, or other forms.
2. 2. Mechanism for securing and actuating adjustable and removable blade closures, as in the preceding claim, which is characterized by the fact of packing 4, 5, 6, blades out of the opening of facade in decreasing the distance between them to occupy as little space as possible when collecting them. It can be done by reducing the pitch of screw 4, finishing the propeller in a straight rail where are introduced the supports of the blades 5, finishing the screw with a smooth span without propeller 6, by stacking the nuts 9, 10 , or by other forms.
3. 3. Mechanism for securing and actuating adjustable and removable blade closures, as in the preceding claim, which is characterized by having devices for attaching the blades 7, 8, 9, 10 to the screws without end. These devices do not prevent the blade from rotating on its longitudinal axis, and they allow the translational movement of the blades along the screws. These mechanisms can be formed by bars 7 fixed to the blades in extension of them, with a bearing 8 at its end which is seized to the spiral of the screw; or nuts 9 to which the screws 3 are wound and which take the bars 7 fixed to the blades; or nuts with a horizontal striated surface which support the bearings 13 attached to the bars 7 which support the blades, or by other forms.
4. 4. Mechanism for securing and actuating orientable and removable slide fasteners, as in the preceding claim, characterized by producing movement along the screws by means of the devices 14, 15, 16, preventing rotation of the devices. securing the blades 7, 8, 9 around the axes of the screws. These devices may be formed by a cylindrical tube 14 with a longitudinal groove 17 which forces the bars 7 to move there; a fixed vertical plate 15 which prevents the bars from descending by turning through the helix of the screw 3; a vertical plate 16 which fits into the notches 18 made in the outer surface of the nuts 10 by fixing its position, or by other forms.
5. 5. Mechanism of rotation of the blades on their longitudinal axis by means of a pinion 19, located in the securing bars 7 of the blades, and with the same longitudinal axis. The rotation is triggered by a mechanism comprising a rocking rack 20, which is taken by two parallel axes 21 to a fixed plate 22 to actuate in vertical movement by a lever 23, by pressing or releasing the pinions 19. In the rest position the gables must be grasped to maintain the inclination of the blades. Once released, the blades can move in the direction of the axis of the screw. The shape of the pinion 19 may be a span of the same bar 7 with the striated surface. The rack 20 can also be actuated by a mechanism comprising a pinion 24 with two positions, moved from the rack or facing it, the displacement from one position to the other is done by means of a central axis 25 which in turn push rods 26 that were fixed to the ends of the gears. 24.

In the case of securing the blade by means of a nut 10 the inclination mechanism will be a frustoconical bearing 13 fixed to the end of the bar 7 which is placed on a horizontal striated surface 12 located in the nut 10. By means of a vertical plate 16 which fixes the position of the securing parts 10 are rotated so that the striated surface moves horizontally while the frustoconical bearing 13 rotates, or by other forms.
