Description

JOINERY WITH SWIVEL BLADES SUCH AS A PERGOLA

FIELD OF APPLICATION OF THE INVENTION

The present invention relates to the field of joineries with rotating blades such as a pergola and in particular adaptations to allow the pivoting in the best conditions. DESCRIPTION OF THE PRIOR ART

A pergola is a small garden construction that conventionally includes a perforated roof associated with columns.

More recently, the pergola has evolved by providing a roof formed of a frame supporting pivoting blades arranged and dimensioned so that their edges overlap in a certain position. The adjustment of the swivel makes it possible to regulate the sunshine and ventilation which the user wishes to obtain. In addition, a complete overlap makes it possible to obtain an enclosed black roof that protects against rain.

A problem with pivoting blade configurations lies in the difficulty of allowing pivoting of the blades when the frame supporting the blades (and therefore their axis of rotation) has non-parallel sides with faces of profiles facing each other, of which at least one is oblique (trapezoidal frame) or non-rectilinear (curved sections). This configuration can be very useful in a situation where the terrace or the walls bordering the terrace has a profile not straight.

A solution for covering such a surface consists in providing a pergola in several parts, namely: a first part having a roof with a frame forming a straight quadrilateral supporting pivoting blades; a second part having a roof with a frame forming a triangle (for a trapezoidal surface) supporting non-pivoting blades.

Thus, the entire covered area does not benefit from the advantages of the swivel blades.

Another solution is to provide blades in several parts: a first movable part with straight ends, a second fixed part supporting the axis of rotation of the movable part at a right end and a beveled or preformed end with the angle or profile of the roof frame.

Such a solution requires the realization of fixed blades and mobile blades adapted and custom.

Another solution is to provide customized beveled or pre-formed edge swivel blades with custom-made rotating shafts to match the non-straight angle formed by the profile supporting the rotating shafts with the other frame profiles.

The realization of customized solution is particularly expensive and requires, for some parts, a very high precision or requires a particularly long exposure time.

These disadvantages are therefore detrimental to the full commercial development of pivoting pergolas.

There are other joineries with rotating blades such as blinds, blinds, etc ... may have the same disadvantages if the frame that supports the blades has at least one side not parallel to the other or non-rectilinear.

DESCRIPTION OF THE INVENTION

Based on this state of affairs and pre-established specifications, the applicant has conducted research aimed at solving the disadvantages described above. This research has resulted in the design and implementation of a pivoting blade carpentry with new features by providing a blade joint solution overcoming the disadvantages of the prior art.

The pivoting blade carpentry of the invention is of the type comprising a frame of profiles, two sections of the frame, said support profiles being arranged with faces facing each other and supporting rotation shafts of said blades, at least one face facing vis-à-vis being oblique or non-rectilinear.

This joinery is remarkable in that the end of the blades cooperating with the oblique or non-rectilinear face is preformed to follow said oblique or non-rectilinear face, said preformed blade end being equipped with a shaft whose first end is connected to the preformed blade end and whose second end is hingedly connected to said oblique or non-rectilinear face, the hinge comprising an axis of rotation perpendicular to the axis of rotation of the blade to make the link between the blade preformed end of the blades and said oblique or non-rectilinear face.

This feature is particularly advantageous in that it allows the articulation of the blades regardless of the angle taken by the oblique or non-rectilinear support profile. It is not necessary to keep fixed part of the blades forming the roof of a pergola. It is also not necessary to give up rotating the end of the blades. In addition, the proposed joint can be used on several woodwork with different angles avoiding the custom made of each joint or joint for each different angle of frame carpentry.

The woodwork of the invention makes it much easier and cheaper to envisage non-straight roof shapes.

According to another particularly advantageous feature of the invention, the connection between the second end of the shaft and said oblique or non-rectilinear face comprises a bearing which, accommodating said second end of the shaft, is articulated around a platen of fixation attaching to said oblique or non-rectilinear face. Such a solution allows to combine strength and compactness to allow the support of the blades and allow their rotation.

According to another particularly advantageous feature of the invention, said plate is preformed to slide on the oblique or non-rectilinear face of the preformed profile for this purpose. This feature facilitates the assembly of the blades.

According to a particularly advantageous characteristic, said joinery is a pergola, said frame adopting the shape of a trapezium and according to another more precise characteristic, said trapezium is a rectangular trapezoid. Nevertheless, the proposed joint can also be adapted to a carpentry with a straight frame or having a curved frame. The invention also comprises, in association or not, all or part of the following features: said bearing comprises a preformed body of a recess adopting a circular profile whose axis is oriented to be parallel to the pivot axis of the blade and which is open upward to accommodate the second end of the shaft equipping said preformed end of the blade; said bearing is preformed in its recessed portion, a groove in which is engaged at least one preformed lug in the second end of the shaft equipping said preformed end of the blade; said bearing body is extended at one end with a non-recessed extension in connection with the plate and preformed with an orifice having an axis perpendicular to the axis of the circular profile; said platen is preformed to slide in the oblique or non-rectilinear face of said support profile and to present at least one preformed perpendicular projection of an axis orifice perpendicular to the axis of rotation of the blades, a hinge shaft passing through the extension of the bearing and said projection of the plate in order to implement a pivot connection; - Said articulation shaft has a threaded portion for maintaining the bearing in position relative to the platen, once said bearing well oriented.

The basic concepts of the invention having been described above in their most elementary form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving non-limiting example, an embodiment of a pergola according to the invention.

DESCRIPTION OF A PREFERRED EMBODIMENT

Only the frame 100 constituting the roof of a pergola P (not shown in its entirety) is illustrated in the drawing of Figure 1. This frame 100 is constituted by an assembly of profiles supported by uprights (not shown).

According to the invention, said frame 100 adopts the shape of a rectangle trapezium formed by the assembly of four sections 110, 120, 130 and 140 connected by their ends and arranged vis-à-vis two-to-two.

According to a rectangular trapezoidal geometry, the profiles 110 and 120 are arranged facing each other, but the profile 120 has a connection angle with the ends of the profiles 130 and 140 different from ninety degrees so that the profiles 110 and 120 are not parallel to each other and that their face vis-à-vis are not parallel to each other.

The non-parallel profiles 110 and 120 are said supports because they support the rotation shafts of the blades 200 along an axis A parallel parallel profiles 130 and 140.

As shown in the drawing of Figure 2, the blades 200 overlap in the closed position and are designed so that their axis of rotation A is positioned on one of their longitudinal edges. The rotational movement of the blades 200 along the arrow F1 to an open position is synchronized and implemented by means of movement not shown.

As further illustrated in the drawing of Figure 3, the implementation of the pivot connection between the right side of the pergola and the shafts of the blades 200 is performed as described below. The end 210 of the blade 200 is straight (lateral edge perpendicular to the longitudinal edges) and is equipped with a horizontal rotation shaft 300, each end 310 and 320 is equipped with a sleeve 330 and 340. The sleeve 330 is in position. connection with the end 210 of the blade 200 and the sleeve 340 is in connection with a bearing 400 fixed to the profile 110. This bearing 400 adopts a circular profile open at the top and in which is engaged from above, the sleeve 340 of the shaft 300 equipping the blade 200 when mounting the pergola P. A plate 410 is screwed on the bearing 400 to retain the sleeve 340 in the bearing 400. The shaft 300 rotates in the sleeves 330 and 340.

The bearing 400 is preformed on its rear part so as to cooperate with a groove 111 formed in the face vis-à-vis the section 110 to allow the sliding of the bearing 400. This bearing 400 is, once well positioned fixed by one or more screws (not shown).

As further illustrated in the drawing of FIG. 4, the implementation of the pivot connection between the non-straight side of the P-pergola and the shafts of the blades 200 is performed as described below. The end 220 of the blade 200 is beveled (side edge parallel to the profile 120) and is equipped with a horizontal shaft 500 (identical to the shaft 300), each end 510 and 520 is equipped with a sleeve 530 540. The sleeve 530 is connected to the end 220 of the blade 200 and the sleeve 540 is connected to an articulated bearing 600 fixed to the profile 120 by means of a plate 700. This bearing 600 and its plate 700 are articulated about a vertical axis B perpendicular to the axis A and to support the shaft 500 despite the fact that the axis A is not perpendicular to the profile 120. This joint makes it possible to steer the bearing 600 in the position to respect the parallelism between the blades 200, and the parallelism of the blades 200 with the two profiles 130 and 140 despite the support by a profile forming the oblique side of the rectangle trapezoid.

This hinged bearing 600 and the plate 700 are illustrated in more detail in the drawings of FIGS. 5 to 9.

As illustrated, the bearing 600 comprises a preformed body of a recess adopting a circular profile of axis parallel to the pivot axis A of the blade 200 and open upwards in which is engaged, from above, the sleeve 540 of the shaft 500 equipping the beveled end of the blade 200 during mounting of the pergola P. A plate 610 is screwed on the bearing 600 to close and retain the sleeve 540 in the bearing 600. The shaft 500 rotates in sleeves 530 and 540.

To also achieve axial retention, said bearing 600 is preformed with a groove 620 in which is engaged at least one lug (not shown) preformed in the sleeve 540 of the shaft 500 equipping the blade 200.

Said bearing body 600 extends rearwardly at one end with an extension 630 in connection with the plate 700 and preformed with an orifice 640 having an axis perpendicular to the axis of the circular profile. Said plate 700 is preformed on its rear part so as to cooperate with two grooves 121 and 122 formed in the opposite face of the profile 120 to allow the sliding of the hinge bearing along the profile. According to the illustrated embodiment, the profile of the profile 120 is identical to that of the profile 110. Two screws 710 are used to press the plate 700 on the preformed lugs in the grooves and ribs with which it cooperates.

Said plate 700 further comprises two horizontal projections 720 and 730 preformed an orifice 740 axis perpendicular to the axis of rotation of the blades 200. The extension 630 of the bearing 600 is disposed between the two projections 720 and 730.

A hinge shaft here constituted by a screw 750 passes through the extension 630 of the bearing and projections 720 and 730 of the plate to implement a pivot connection which, once the proper orientation of the bearing 600 obtained, becomes a recess connection by screwing screw 750.

It is understood that the pergola, which has just been described and shown above, was for a disclosure rather than a limitation. Of course, various arrangements, modifications and improvements may be made to the example above, without departing from the scope of the invention.
