For example, the device comprises a plurality of blades, said blades means activation being connected to a first blade and said first blade is related to other blades through a connection element.

For example, the activation means comprise an activation rod destiny to be activated by a user, said rod being connected to an arm of lever which is connected to said at least one blade.

For example, a structure includes the covering device such as defined in this application; and at least two support members, said support members comprising each at least one groove, said at least one groove being intended to receiving said at least one blade support.

For example, said support members include two members of support linked together by two transverse members generally arranged parallel to said one or more blades, said support members and said members transverse forming a frame for maintaining said at least one blade.

For example, the structure also includes at least two rods vertical for maintaining said frame and said at least one blade at a height desired.

For example, said transverse members each comprise at least a groove.

The examples presented in this section are non-limiting and presented in the purpose of exemplifying different variants of the technology of this disclosure.

In order to develop a new roof option, a system of blades on pivots is described in this application. The system allows to adjust the opening blades and as well as the entry of light. For example, the blades can to be semi transparent to let in light even when closed. For example, for be done, a smoked polycarbonate window is inserted between two extrusions aluminum which constitute the main structure of the blade. The window of polycarbonate is extruded and not curved out of the mold. She then slipped into aluminum extrusions which are curved.

A sealant can be applied during insertion and as well as end caps (by example), which will close the assembly by screwing blade ends. For example, in order to avoid a joint that would cause of sealing problems, the blades can consist of a single length about 10 feet. For this reason, the different components must to be as light as possible but also strong. For example, the blades can also measure between 3 and 12 feet.

The blades can also be rainproof and therefore, when closed, the blades must be able to drain water. For this reason, and for improve the structural strength of the boards, the boards have a factory curved profile and who will offer an ascending curve at the midpoint of the blade once installed. Through example, the blades can have an aluminum profile.

In this way, the water can flow from the middle of the roof to the ends of blades. Therefore, the roof can keep its solidity thanks to the curvature of the blades.
The advantage of this structure is, without the curvature of the blades, the strength of the gravity would cause the middle of the blades to collapse when water falls or collects above the roof. The curvature of the blade reduces the force of the gravity of the water who would otherwise exerted on the blade. So it also makes it possible to make blades lighter curves and with less material, compared to blades which are more thick and resistant to the force of gravity of water; therefore we can lower the costs of production and manufacture of blades.

It is also desirable to have blades which allow evacuation efficient water accumulated above the roof. It is also desirable to reduce the thickness of the blades to reduce production and manufacturing costs.

The system is operated manually using a sliding handle installed on one of the legs of the structure. This sliding handle uses the grooves paw to slide on casters and offer vertical sliding.
When activated, the vertical sliding of the handle system on casters is transformed into pivot by different rods on offset pivots. These rods are connected to different pivot points as well as the first blade of the system which will rotate due to the conversion of the movement of sliding the handle in rotation thanks to the rods on pivots.

To facilitate the rotation of the blades and reduce the effort required for the consumer, the plastic end caps have been adapted to the curve.

The pivot point of each blade which receives the bearing in the end caps a been positioned so that it is at the neutral point of the blade (see Figurell). This way the blade can rotate without ever causing a moment of inertia and therefore require constant force.

It is estimated that since the blades are in neutral, the force required to activate the mechanism will be the weight of the handle as well as the friction of the mechanism.

The roof will be installable by the user using systems of nut fixing in T, as described in the present application, and this, in all simplicity and with a minimum of parts.

Profile groove Groove present on each of faces of the structural profile. She is 27 used as as support for the Faste ners fasteners and works on a "T" insert principle

Referring to Figure 1, a structure 1 consists of a number elements constituent units of the structure after assembly. For example, the structure 1 may consist of a covering device and a support.

The cover device and / or the support device may have a section rectangular or square. The structure can be modular, versatile, freestanding, or fixable to a support, such as a wall. The modularity of the structure allows various configurations and positions.

The covering device comprises a support means intended to be attached to structure support device. Referring again to Figure 1, the structure freestanding (1) is composed of profiles (for example, legs 9 and the beam 8) obtained by aluminum extrusion. The structure can use one or more profiles, the latter can vary in length to accommodate the use that one wish in make (legs, beams, cross, reinforcements, supports).

As illustrated in Figure 8, the groove (27) serves as an element of support can receive the options and assemblies provided as additions to the structure freestanding, the latter was developed specifically for this use.
The groove (27) uses a T-insertion principle which allows a hardware store developed as part of the project to serve as support. However, use required of this groove does not limit its shape, different principles of grooves could be used in the same way with a different profile, as examples those shown in Figure 8. Figure 9 shows a view of the heart of the main profile of Figure 8. Figures 10A, 10B and 10C represent nt views of "T" nuts and their installation in the main profile of Figure 8.

As shown in Figures 8, 10A, 10B and 10C, the "T" nut 12a of them chamfers that allow rotation once inserted into the profile principal of the structure. The nut can apply the clamping force that holds the fastener fastener in place when screwing

Referring to Figures 13, 14 and 15, the structure (1) can be assembled with a principle of corners (connectors) (36) which serve as an attachment point between the profiles (37, 38 and 39) of the structure. This assembly can be mechanically welded and composed at using aluminum extrusion profiles (48) to support the beams horizontal (support members and transverse members) of the whole structure in fitting into the legs (vertical rods) of the structure. For example, the connector assembly (36) is hidden by an ornamental cube (49) ayan legs (30). The ornamental cube can also serve to preserve aesthetics cubic of the structure (Figures 14 and 15). The connector (36) is assembled so as to orient its rods (48) in the direction of the X, Y and Z axes. These rods are then inserted in the core of the profile (39) of the structure. For example, as illustrated in Figure 14, threaded inserts (31) may be present in each of the rods (48) then allow mechanical assembly of the profiles to the connectors the help of screw. Different variants of connectors have been developed to allow the connection of several structures using the same support point (paw).

Referring again to Figure 1, the device support means of cover can be a horizontal structure 8. For example, the means of support can be a horizontal beam. The beam can be adapted to support the cover device. The covering device can be an assembly 13 of roof at blades 14.

The blade can be pivoted between an open position and a position closed to form a coverage area. The blade may include a means of bearing allowing the blade to pivot.

The blade can include a first curved member, which defines a area curved when the blade is in the closed position. By curved surface, we under-hears that the blade is bent down, i.e. the blade has a curve ascending. Because of this, the two ends of the blade point down, while the middle point of the blade points upwards. The ascending curve is at midpoint of the blade. Thanks to the ascending curve, the blade is able to evacuate the water which falls to above its surface. Thus, water can flow from the midpoint of the blade towards the extremities. Once at the end of the blade, the water is drained off.
For example, when it rains, water will collect above the surface of the blade.
But the blade can keep its solidity under the weight of water thanks to its curve. Without the curve, the force of gravity of the water accumulated above the surface of the blade would do sag the middle or part of the blade surface.

The curved surface of the blade can extend along the blade for form a arc in the longitudinal direction of the blade.

The blade can have a transparent or semi-transparent material. Through example the material may be polycarbonate. The material can be smoked.

The blades can constitute protective screens. The blades can be orientable. The adjustable blades can extend parallel to each other to the other. The blades are preferably orientable blades extending the some behind the others being parallel to each other and preferably all identical.

The number and dimensions of the blades are adapted to the dimensions of the area cover. For example, the planks can together form a shaped roof rectangular. For example, the blades are all mounted in the same direction.
The blades have an upper face and a lower face intended respectively to face up and down in the closed position.

The blades can have a curvature along a longitudinal axis.
When a fluid (such as water) falls on the blades in the closed position, the curvature allows the fluid to slip and accumulate on the transverse sides of the blades. The recovery of fluid can be done on the transverse sides of the blades. For example, it can have a tube on the transverse sides of the boards to evacuate water from the roof formed by the blades.

The blades can be opened or closed. Blades can open where close according to a sliding mechanism. Referring to Figure 1, the blades 14 are in a closed position. Referring to Figure 2, the blades 14 are in an open position. As shown in Figure 1, the blades have a curvature in the longitudinal direction. For example, when it rains, the curvature blades guide the water to the sides of the blades. This therefore prevents water from stay and / or to accumulate above the covering device.

When closed, the blades extend to form an area of blanket. The blades can be opened or closed by a system of sliding. The structure support device is connected to the device cover to keep the structure in an upright position.

Different styles of blades can be used in the device cover, y including insulated blades and polycarbonate blades, or alternatives as glass slides and coating slides comprising both aluminum and polyvinyl chloride. These blades may be permeable to light.

Referring to Figure 3A, a perspective view of a blade 14 is shown.
Figure 3B shows a cross section of the blade of Figure 3A along the axis XX.
In Figure 3B, the lines represent the cross section and the lines in dotted lines represent a tip located at the end of the blade.

The blade 14 includes a first member 16, a second member 15a and a third member 15b. The first member 16 can be framed by the second member 15a and the third member 15b. In Figure 3A, the second member 15a and the third member 15b are placed on each side of the first member 16.

The second member 15a and the third member 15b can The second member 15a and the third member 15b can be made of aluminum. Through example, the second member and the third member can be extrusions aluminum. For example, the second member and the third member can formed the main structure of the blade.

For example, the second member and the third member can extend it along the first limb. The second member and the third member may each to be bonded to one of the opposite and parallel sides of a first pair of sides opposites of the first member. So the first member is between the second member and the third member. The first member can include each of opposite sides of the first pair of opposite sides, a tab for to be inserted into a groove defined by the second or third member.

The second and third members may each include a seal muffler 26 to prevent slamming when blades are in contact.
The silent seal can be applied to the ends of the blades to avoid clicks when they come into contact. Referring to Figure 3B, joints mufflers 26 are placed on the ends of the blade. For example, a joint may be connected to the second member; and another joint can be connected to the third member. The first member can be made of polycarbonate. For example, the first member may be an extrusion of polycarbonate. The first member can act as fenestration for the blade. The first member can be supervised by a aluminum extrusion.

The blade may include a rolling means allowing the blade to swing. The blade may include a second pair of opposite sides. Each of opposite sides of the second pair is linked to a tip comprising the means of bearing allowing the blade to pivot. The rolling means is positioned at level of the blade dead center, so that the blade can pivot without create moment of inertia.

In Figure 3A, tips 17 are connected to the ends of the blade.
The tips are used to attach the blade to the structure. Figure 5 shows a view of the tip 17. The tip can link the different extrusions of the blade.
The tip can be plastic, aluminum, or other suitable material.

The tip includes a ball bearing 18 which serves as a pivot point and allows the blade to pivot. The ball bearing supports the blade on the support and facilitates its rotation.

The tip includes an attachment point 53 which allows the blade to be connected to the element of connection 21 as shown in Figure 4. Figure 4 shows the element of connection 21 connected to the blades 14. The connection element 21 can be connected to each attachment point of the tips 17 of the blades 14 for their movement simultaneous when opening / closing the blades. For example, the connection element automatically activates all the blades when one of them is activated. Figure 2 also shows the connection element 21.

A blade support can be used to fix the blade to at least one member of support of the structure. The blade holder may include one end destiny to be inserted into the ball bearing of the blade. The blade holder can include an end intended to be inserted into the support member.
Figures 7A and 7B show a blade support 19 comprising a rod 61. The support Blade 19 serves as the blade attachment point on a horizontal beam 8 of the Figure 1. The rod 61 can be inserted into the tip 17 of the blade. More Exactly there rod 61 can be inserted into the ball bearing 18 of the end piece 17 of a blade and be secured by a nut. A T-Nut 12 can be used to fix the blade support 19 in the groove of the structure 8. For example, the nut may be rectangular with two chamfers which allow a rotation of 1/4 "a time inserted in the main profile of the structure. It is this nut which apply force clamping device which keeps the fastener fastener in place during screwing.

Activation means can allow the pivot or the blades swivel between the open position and the closed position. For example, the way activation may include a sliding system. Activation means can be connected to a first blade. The first blade can be connected to other blades through a connection element. The means of activation can comprise an activation rod intended to be activated by a user.
The rod can be connected to a lever arm which is connected to a blade or blades.

Figures 6A, 6B and 6C show a sliding system 600. The system of sliding allows opening and closing of the blades. The system of sliding may include a lever arm 20, a connecting member 22, a rod activation 23, a guide support 24, and a handle 25.

The lever arm can be a direct connection installed on the tip of a blade. For example, the lever arm can be connected to the ball bearing of a blade. The lever arm can rotate a blade when activated speak sliding system to put the blade in a closed position or opened.

On the other hand, the lever arm 20 can be connected to an element fitting 22. The connecting element 22 connects the lever arm to the activation rod 23 for transmit an activation force to the lever arm when sliding is activated.

The activation rod 23 is connected to the activation handle 25 which backstage in the groove of the structure tab. It allows transmits the movement of the handle 25 to the connecting blade. The guide support 24 ensures the positioning of the rod activation as well as its sliding. The activation handle 25 can slide in the groove of the structure leg. The handle 25 activates the sliding and is the user's direct contact on opening / closing of blades.

The lever arm 20 can be connected to the connection point 51 of a tip of a first blade to rotate it as shown in Figures 6A and 6B. This swiveling allows the blade to be opened or closed. When the lever arm acts on this first blade, the force exerted on this first blade will propagate in others blades via the connection element 21, which is connected to the end caps other blades. This allows you to rotate, so open and close, others blades simultaneously simultaneously when opening / closing the first blade. Thanks to the connection element 21, a user can activate automatically all the blades when using the sliding system.

Figure 8 show the installation of the blade support in the beam 8. The structure has a groove 27. The groove can be present on each of the faces of structural profile. It is used as a support for fasteners Fasteners and works on a "T" insert principle. The structure has a heart10. The profile of heart can be square. The heart can receive the connector rods for the assembly of the structure. In Figure 8, the blade holder is secure in the groove 27 of the beam 8. Figure 11 shows the installation of a blade in the support blade installed in a structure, such as beam 8 in Figure 8.

Figure 12 shows the curvature of the blade 14 along a longitudinal axis X
who defines a neutral point Xm. The arc of curvature can have an acute angle ANG with the axis longitudinal X. The blade 14 can be connected by means of support of the device cover via end caps 17. The acute angle may vary between 0 to 45 degrees.

In another aspect, the present disclosure demonstrates a new type roof.
In particular, the present disclosure presents a system of blades on pivots which allow to adjust the aperture and thus the light entry. For example, this system of blades has semi transparent blades which let in light even when closed. To do this, a smoked polycarbonate window is inserted between two aluminum extrusions which constitute the main structure of the blade. The window polycarbonate is extruded and not bent at the exit of the mold. She then swiped in the aluminum extrusions which they are curved. A sealer is applied when insertion and as well as end caps (such as plastic end caps) which will close the assembly by screwing at the ends of the blades. Also, in the purpose of avoiding a gasket which would cause sealing problems, the blades are consist of a single length (for example about 10 feet). For this reason, the different components must be as light as possible but also solid.

For example, this blade system is rainproof and therefore, when closed, the blades are able to evacuate the water. For this reason, and for improve structural strength of the boards, this disclosure presents a profiled of aluminum which will be bent at the factory and which will offer an ascending curve point middle of the blade once installed. This way the water can flow from the middle blades and towards the ends of the blades. Thus, the blades retain their solidity thanks to the curve which against the force of gravity which would cause the middle of these last otherwise.

For example, the system can be operated manually using a handle sliding installed on one of the legs of the structure that supports the roof of blades.
To facilitate the rotation of the blades and reduce the effort required for the consumer, the end caps (for example, the plastic end caps) have been adapted to the curve. The pivot point that accommodates the bearing in the end caps has been positioned way to find itself at the neutral point of the blade (see figell). Of this way the blade can pivot without ever causing a moment of inertia and therefore, requiring a constant force. Since the blades are in neutral, the force necessary to activate the mechanism will be the weight of the handle as well as the friction of the mechanism. The roof can be installable by a user using systems T-nut fixing.

Support members and members transverse form a frame to maintain the blades. The members transverse may each include at least one groove. The stems vertical may each include at least one groove. For example, the two members support can be interchangeable with the transverse members.

The support members can be interchangeable with the members transverse or with vertical rods. For example, at least two members of support can be interchangeable with the transverse members or with minus two vertical rods.

The structure can also include at least two vertical rods allowing the frame and the blades to be kept at a desired height.

For example, the support members, the transverse members and the stems vertical can be intended to be interconnected through connectors. The connectors can be provided with branches intended to be inserted in support member, cross member and / or rod cavities vertical. The connectors can be intended to be placed at the corners of the frame and be dimensioned so that the branches are concealed from inside support members, transverse members and / or vertical rods when inserted into them.
