DESCRIPTION

PERGOLA

TECHNICAL SECTOR

The present invention refers to a pergola of the type provided with slats that can be tilted and also retracted. In this way, in this type of pergolas it is possible to obtain total visibility, total coverage, or any intermediate configuration. In particular, the pergola object of the invention offers very high performance from the point of view of sealing.

BACKGROUND

A type of pergola provided with adjustable and retractable slats is known. By adjustable it is meant that their slats can be tilted on the one hand, to define various degrees of shading and on the other hand, they can also be folded up to leave a clear opening.

In order to facilitate the interpretation of the following text, it is possible to define in these pergolas, a longitudinal direction, a transversal direction and a height direction perpendicular to the longitudinal direction and the transversal direction, so that the slats extend according to the direction They can be moved transversely along the longitudinal direction and can be oriented by rotating along an axis of rotation in the transverse direction.

For this, this pergola comprises, in a known way:

- two lateral support profiles arranged according to the longitudinal direction;

- two pantographs, each one guided by one of the lateral profiles;

- the pantographs being formed by pairs of successively articulated connecting rods;

- defining in each pair of connecting rods an axis of articulation between each connecting rod of the pair, and defining in each connecting rod an upper section located above the axis of articulation and a lower section located below the axis of articulation,

- defining in each slat a rear semi-slat and a front semi-slat, the front semi-slat being the one that remains above the rear semi-slat when the slats are inclined.

Such a pergola is known, for example, from the publication US2014130988A1.

The pantograph mechanism offers many possibilities for the kinematics of the slats, since this is defined by the mechanical links established between the slats and the pantograph, and they can be very varied.

In the option selected in US2014130988A1, the mechanical link consists in the fact that the slats can rotate around axes arranged in the centers of the slats, and these axes are guided longitudinally. Rotational movement is accomplished by pin and slot links at the top and bottom ends of the slats.

However, this solution, due to its construction, can present sealing problems, since in the most horizontal configuration, the moment exerted by the pairs of slot pins is very low because the point where the force is exerted is very close to the central axis. . This means that the pressure between consecutive slats cannot be high and may present sealing problems.

In addition, the kinematics based on a central axis offers few possibilities from the point of view of sealing at the ends of the slats, which makes it necessary to finish off the top with some type of cantilevered edge.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

In the description of the possible preferred embodiments of the invention, it is necessary to give numerous details in order to promote a better understanding of the invention. Even so, it will be apparent to one skilled in the art that the invention can be implemented without these specific details. On the other hand, well-known features have not been described in detail to avoid unnecessarily complicating the description.

As can be seen in figure 1, according to a preferred embodiment, the pergola E is provided with adjustable and retractable slats L, L1, L2, Ln, in which a longitudinal direction DL, a transversal direction DT and a direction of movement are defined. height DH perpendicular to the longitudinal direction DL and the transverse direction DT, so that the slats extend in the transverse direction DT, can be moved along the longitudinal direction DL and can be oriented by rotation along an axis of rotation in the transverse direction DT .

The pergola also comprises two lateral support profiles P1, P2 arranged along the longitudinal direction DL.

As can be seen in the figures, each slat (L, L1, L2,..., Ln) includes two ends (LF) in which the slats are attached to the orientation and retraction mechanism.

As can be seen in the figures, according to the invention, the lateral profiles P1, P2 comprise joints JL having longitudinal direction DL and which are arranged under the ends LF of the slats L, L1, L2,..., Ln and oriented towards the slats L, L1, L2, ..., Ln, the slats L, L1, L2, ..., Ln being articulated so that in their maximum extension configuration, the slats L, L1, L2, . , Ln are arranged horizontally and support each other in the longitudinal sealing joint JL. In addition, the lateral support profiles P1, P2 each comprise a drainage channel CX arranged under the ends LF of the slats L, L1, L2, Ln, so that a wing is defined on the lateral support profiles P1, P2 interior WI, an upper end of the interior wing WI being provided with the longitudinal sealing gasket JL.

In the illustrated embodiment, the pergola comprises two pantographs PA1, (PA2 not shown but parallel to PA1), each guided by one of the lateral profiles P1, P2;

As can be seen in figures 9 and 10, the pantographs PA1, PA2 are formed by pairs of connecting rods B1, B2 successively articulated; so that in each pair of connecting rods B1, B2 an axis of articulation B12 is defined between each connecting rod B1, B2 of the pair, and in each connecting rod B1 an upper section B1S, B2S located above the axis of articulation B12 and a lower section B1I, B2I located below the axis of articulation B12.

These sections are defined here to be able to describe the movement of the slats L.

Each slat L, L1, L2, ..., Ln defines a rear half-slat LB and a front half-slat LF, the front half-slat LF being the one that is above the rear half-slat LB when the slats L, L1, L2, ..., Ln are inclined.

According to this embodiment, each slat L, L1, L2,..., Ln is hinged at each of its ends with a pair of connecting rods B1, B2, such that:

- the rear semi-slat LB of the slat L, L1, L2,..., Ln is articulated with the lower section B1S of one of the connecting rods B1 by means of an axis B1L; and

- the front half-slat LF of the slat L, L1, L2, . , Ln is articulated with the upper section B2S of the other of the connecting rods B2 of the pair B1, B2 by means of a pin link B2P and a pin guide LC.

This particular link has two effects:

First of all, it allows all the points of the slats to have a downward movement in their last downward path, which makes it possible to provide, as will be seen below, a longitudinal joint JL on which the ends of the slats can rest. slats and thus achieve a high degree of tightness. Figures 7 and 8 show the joint in section longitudinal and its effect. In particular, it can be seen in figure 8 how the slat bodies LB are supported on the joint JL. In the figure JL is represented as if it had not been deformed, but obviously the contact lip JLB will be below the body of the louver LB.

Secondly, since the slats are articulated by means of an axis that remains in a rear semi-slat, and since the pin is arranged in the front semi-slat, the force exerted by the guide on the pin allows a high moment to be generated on the slat which leads it to press correctly on the next slat, which guarantees total tightness between slats. To do this, the front end of the front half-slats and the rear end of the rear half-slats have complementary shapes so that in the configuration of completely horizontal slats, said ends support each other, preferably with the interposition of a JE sealing gasket. and also preferably, the articulation axis B1L between connecting rod B1 and slat L is arranged at a distance from the articulation axis B12 between connecting rods B1, B2 that is comprised between a quarter and a third of the distance between the articulation axis B12 between connecting rods B1, B2 and the joint axis CC with a successive connecting rod.

As can be seen in figure 9, the slats L, L1, L2,..., Ln are made up of a slat body LB and respective covers CL at each of their ends, so that the covers CL transmit the forces between the pantograph PA1, PA2 and the slat body.

The CL covers comprise a lower section CLI coinciding with the profile of the slat bodies LB and an upper section CLS provided with the LC pin guide.

The upper section CLS of the covers CL is arranged with respect to the lower section CLI so that in the pantograph situation in its maximum extension configuration, the slats L, L1, L2, . , Ln are arranged horizontally.

As can be seen in figures 7 and 8, the CL covers have a larger cross section than the slat body so that in a horizontal configuration, the CL covers have a lower edge CLD arranged below the height of the slat body. lama LB.

In this way, the water (represented by a drop AG in figure 8) that may fall down the side of the cover will not adhere to the body of the slat with the possible risk of it being carried to the space provided under the slats, otherwise it will end up falling into the space provided under the CL cover, where there is a channel CX for collecting and channeling the water.

The pergola preferably comprises on each side a drag slide D guided by one of the lateral support profiles P1, P2, the drag slide D being articulated with the last pair of connecting rods B1, B2. The lower shafts B1L are guided in the longitudinal direction DL, and the drag slider D is attached to the lower shaft B1L of the most advanced connecting rod.

The pergola comprises a drive motor M and arranged at one end of the pergola in the longitudinal direction, a transmission pulley RC and a transmission belt CT which transmit the force between the motor M and the drag slider D.

As can be seen in figures 11b, 11d and 11f, the invention can also be implemented with another type of link between slats and pantograph. These figures show an embodiment in which the slats are integral with the pantograph rods that have the inclination of the slats. It can be seen that in this embodiment, the lower end of the slats is hinged with the lower end of the connecting rod, and the lower contour of the slat is circular. Thus, in this solution, all the points of the slat have a negative or zero vertical speed (the lower points), so that they can rest horizontally on the longitudinal joint JL.

Figures 11a, 11c and 11f show the embodiment shown in the other figures, based on a guide and pin. As can be seen, the two solutions shown in these figures allow support at the longitudinal joint, but the progression is different. Specifically, the solution based on guide and pin in figures 11a, 11c and 11f allows a greater range of orientations with the slats extended.

In view of this description and figures, the person skilled in the art will be able to understand that the invention has been described according to some preferred embodiments thereof, but that multiple variations can be introduced in said preferred embodiments, without departing from the object of the invention as such. and as it has been claimed.

In this text, the term "comprising” and its derivations (such as "comprising”, etc.) do not must be understood in an exclusive sense. That is, these terms should not be interpreted as excluding the possibility that what is described and defined may include more elements, stages, etc.
