An opening and closing pergola

Abstract

 Opening and closing pergola is composed of rafters within which it is possible to horizontally move an articulated movement conductor (6) with the use of a special "neck" flange (12). The articulated conductor (6) is connected with an inclined reverse -T shaped holding piece (9) through a forearm (11), and with special holding pieces (8) through an arm (2) and a knee (3) with two branches. Purlin rafters-sheets (1) made of aluminum or iron plate are placed on the special holding pieces (8) which move by the combination of the articulated movement conductor (6) and the inclined reverse -T shaped holding piece (9) in such a way that the opening and closing pergola is either in the open position (the purlin rafters-sheets (1) are perpendicular to the rafters) or in the closed position (the purlin rafters-sheets are horizontal to the rafters).

Description

[0001] The present invention relates to a pergola which is composed of pillars and rafters upon which purlin rafters-sheets are placed with a special application, so that they can move. The purlin rafters-sheets can be aluminum or iron plate.

[0002] On their small side the rafters have an opening, shaped as reverse Π within which an articulated conductor is dragged along the rafters. The other side of the rafters can be joint with pillars. On the articulated conductor there is an adapted arm which forms a junction, almost halfway its length. Its other end is connected with a holding piece. This holding piece has the same shape as the purlin rafters-sheets. On the same junction at a fixed distance relative to the width of the purlin rafters-sheets a cruciform knee is joint (open position of the purlin rafters-sheets). One end of the cruciform knee is connected upon the holding piece and at a small distance from it. The holding piece has the same shape as the purlin rafters-sheets. The other end is connected externally with the rafters. The holding distances of the connected to the junction arm and knee (forearm) are fixed in relation to the width of the holding piece and the lengthside of the purlin rafters-sheets. The arm and the knee are almost parallel when the purlin rafters-sheets are horizontally closed. At a fixed distance, relative to the width of the purlin rafters-sheets, and all along the side of the articulated movement conductor and the correspondent rafters, one end of the arm and the knee are joint together so that the articulated conductor is displaced. The displacement is caused by the cruciform connection, because a resistance is exercised by the connection of the rafters and the knee.

[0003] The other ends of the cruciform, the connection's arm and the knee, are connected with the holding piece, having the same shape as the purlin rafters-sheets which support and hold at the same time the purlin rafters-sheets. The displacement of the articulated conductor displaces accordingly the purlin rafters-sheets which can be aluminum or iron plate, at a horizontal or vertical direction.

[0004] The movement of the articulated conductor that brings the purlin rafters-sheets to the vertical position, opens the pergola.

[0005] Pergolas made of wood, aluminum or iron elements in various. dimensions, shapes and colours are known. The roof of the known pergolas is stable, made of cloth, plastic, ceramic, glass, aluminum slices, iron-plate, stubble constructions e.t.c.

[0006] A pergola with an opening roof exists only made of the same material usually for the entire pergola, presenting significant problems such as noise and wear, mainly because of the wind. Pergolas covered with other materials such as glass, aluminum, iron plate or other materials with significant weight present weight problems as they make the opening of the pergola difficult. The opening is sectioned, thereby making the function of the pergola disandvantageous.

[0007] The present invention has the advantage of being, according to the user's desire, open, having complete ventilation when the user wants, complete or selected shading, and protection from the rain, snow and hailstone, without being firmly stable, having the external image of the pergola with aesthetic and technical advantages. The opening of the pergola is easy and can be made manually without need to practice force even for a large surface (about 36m²). In addition it is possible to install an electrical mechanism intended to the easiest way of opening and closing the open and closing pergola.

[0008] According to the present invention, the opening and closing pergola is supported by two or more rafters, depending on its dimensions (width), that are formed in such a way that while supporting the aluminum or iron plate purlin rafters-sheets, they also have the advantage of moving the articulated movement conductor by the special "neck" flange in their internal section. The rafters are made of aluminum profiles "closed" with external dimension width 2 cm to 20cm, height 2 cm to 25cm and panellings thickness, in proportion to their terminal dimension and because of their supporting stability, 0,6mm to 6mm. The drawings n, 1, 2, 5, 6, 7, 8, 9, 10 show a front and a side view of the rafters.

[0009] The rafters of big dimensions can be used alone while the small rafters can be placed on whatever rafters aluminum, wooden, iron, plastic or other materials.

[0010] Rafters of any dimension have in the upper or down section of their smaller side a special opening in the shape of a, reversed Π (7) where by a special "neck" flange (12) the articulated conductor (6) is displaced along the side of the rafters.

[0011] The articulated conductor (6) is made of plastic or aluminum with dimensions (width, thickness, height, and length) analogous to those of the rafters additively so that the conductor is easily dragged by the special "neck" flange (12) having the required tolerance.

[0012] On the special "neck" flange (12) of the articulated conductor the arm (2) for the movement of the purlin rafters-sheets (1) of the open closing pergola is supported with one end, while on the same supporting point, the articulated movement conductor (6) is held, supported and dragged by the special "neck" flange, keeping a distance from the rafters. The arm (2) is out of the rafters in the opening of the reversed Π (7) and the other end, is connected with the special holding piece which has the same shape as the covering purlin rafters-sheets of the open closing pergola (1).

[0013] The special holding piece of the purlin rafters-sheets (8) has analogous dimensions to the dimensions of the purlin rafters-sheets (1) and slightly folded ends that hold the purlin rafters-sheets. The number of the holders corresponds to the number of the puriin rafters-sheets and to the number of the rafters.

[0014] On every holding piece of the purlin rafter sheet (8) and on the same direction to the right of the holding piece of the end of the arm (2) a double knee with two branches (3) and a small axon (4) is placed .

[0015] The knee (3) and the axon (4) are placed in a distance proportionate to the dimensions of the holding piece (8) and in accordance with the dimension of the purlin rafters-sheets (1). A crosswise position is thereby formed in relation to the arm (2) which is placed in-between the two branches of the knee (3). The crossuise position between them is formed when the purlin rafter-sheets (1) are in the vertical position (open pergola). The two branches of the knee (3) are distanced from one another with a millimeters tolerance larger than the width of the rafter (5). The knee (3) has two branches: One end of the branch is connected through the axon (4) with the holding piece (8) of the purlin rarfters-sheets (1). The other end is supported externally by the inner side of the rafters (5).

[0016] The knee (3) with its two branches and the arm (2) is connected on its one end with the special holding piece of the purlin rafters-sheets (8) while the other end is connected with the rafter (5) and the articulated conductor (6) respectively, creating between them a crosswise position. The arm (2) is between the two branches of the knee (3), so that the articulated conductor (6) moves along it horizontally to create an open-close movement of the purlin rafters-sheets (1).

[0017] The design 10 shows a view of the movement of the articulated conductor (6).

[0018] When the articulated conductor (6) is displaced to the left, it closes the pergola's roof and the purlin rafters-sheets (1) are almost on the horizontal position. When moving to the right, it opens the pergola's roof and the purlin rafters-sheets (1) are almost on the vertical position.

[0019] The purlin rafters-sheets (1) of the open closing pergola are composed of aluminum sheets or iron plate sheets in a wavy shape, semicircular, angular, trapezoidal or straight ending in a wavy shape, semicircular, argular, or trapezoidal. The width of the purlin rafters-sheets (1) varies from 0,5 mm to 5 mm in a compact shape or with gap sections according to demand.

[0020] The width of the purlin rafters-sheets (1) of the open closing pergola varies from 5 cm to 125 cm. The shape of the purlin rafters-sheets of the open closing pergola can be wavy, semicircular, angular, trapezoidal and all straight or in sections ending to wavy shape, semicircular, angular, or trapezoidal so that when all the purlin rafters-sheets are in a horizontal position, they connect with each other so as to make the pergola impervious and to create a visually uniform roof which protects from the rain, snow, wind and hailstone. Design 8 shows the movement of the articulated conductor (6), the almost vertical position of the purlin rafters-sheets (1) (open pergola). The almost horizontal position of the purlin rafters-sheet (1) (closed pergola) is shown in design 1.

[0021] Design 4 shows views of purlin rafters-sheets (1) compact, in a wavy shape (14), semicircular shape (17), trapezoidal shape (16), angular shape (15) and with gap in their trunk [(17) and (18)].

[0022] The horizontal movement of the articulated movement conductor (6), is caused by the use of a special closed rectangular aluminum profile (13). This is placed under the rafters (5) and holds on to them with special holders in the shape Ω. An inclined reverse T shaped holding piece is adjusted to the one end of the closed profile (13). The holding piece is connected through the arm (11) and the junction (10) with the articulated conductor (6). On the ends of the head of the inclined reverse T-shaped holding piece (9) chain, rope or braid having the necessary length are placed through which the movement left or right downwards is effected. An electric motor is placed on the same spots for the electric movement of the opening and closing pergola.

[0023] The designs that have been used here, show indicative dimensions of the rafter (5), of the holding piece of the rafters-sheets (8), and of the other elements forming the opening and closing pergola. However it is possible to differentiate their dimensions according to specific requirements.
