Abstract

The assembly, especially for one or more inclined glazing bars (1) extending between a ridge bar and lower purlin, has fastenings (6) at both ends of each bar. One or both end fastenings allow the first (5) and/or second end of each bar to be adjusted in one plane and rotated in another perpendicular to it so it can be placed in a selected position and angle relative to the ridge bar and purlin. The upper fastenings consist of a support (12) attached to the ridge bar and a series of independent components (6) with one end (7) to receive a glazing bar and the other (8) pivoted to the support.

Description

<Desc / Clms Page number 1>

 The invention relates to the field of assembly of roof support structures, and more particularly the assembly of the roof sections between an upper support part, called ridge, and a lower support part, called sand pit.

 Some canopies or verandas, and in particular those called radiant or Victorian, generally have polygonal roofs which are difficult to assemble. More specifically, the difference in level between the ridge and the sandpit, possibly coupled with the fact that the faces of the roof are of unequal dimensions, makes it particularly difficult to fix the ends of the profiles on these ridge and sandpit.

 In order to solve this drawback, it has been proposed to provide the ends of the profiles with first and second fixing means, such as shoes provided with oblong holes for the passage of a stud intended for fixing on the ridge or the plate. These oblong holes offer a degree of freedom of positioning in a vertical plane which facilitates assembly.

However, this solution does not bring complete satisfaction in the case of radiant or Victorian canopies or verandas, in particular.

 The invention therefore aims to provide a different solution from those known. To this end, it proposes an assembly device of the type presented in the introduction, in which the first and / or second fixing means are arranged so as to allow the first and / or second ends of the profiles to have at least one degree of freedom of translation in one plane and one degree of freedom of rotation in another plane, perpendicular to the plane of translation. In this way, each profile of the roof can be placed relative to the ridge and

<Desc / Clms Page number 2>

 sandpit in a chosen position and in a chosen orientation (angle).

 The invention therefore relates either to the first fixing means, or to the second fixing means, or again to both the first and the second fixing means.

 The first fixing means preferably comprise, on the one hand, support means which are secured to the ridge and which define the foreground, and on the other hand, a multiplicity of independent parts which each comprise a first part which it is secured to the first end of a profile and a second part which is mounted on the support means and can be driven in translation and in rotation relative to the latter, respectively in the translation and rotation planes.

 In a preferred embodiment, the support means comprise a hoop of circular cross section to which the second parts of the parts are hung (or suspended), via at least one connecting element defining a passage for the hoop. The word arch must be understood in a broad definition. It can take many forms, such as circular, elliptical, semicircular, polygonal, etc. It is therefore particularly advantageous for the second part of the part and the connecting element to be in one piece, the connecting element then protruding from a rear face of the second part of the part and comprising a cylindrical passage of cross section having a diameter substantially equal, by higher value, to that of the arch.

 Furthermore, it is advantageous that the support means comprise a beam, preferably linear, which is secured to the ridge and on which the arch is fixed. On the other hand, to prevent the arch from sagging, the support means may include a tie rod connecting the arch to the ridge.

 It is also possible to provide a plate forming an L-shaped square, the first part of which is interposed between the ridge and the means of

<Desc / Clms Page number 3>

 support and secured to them, and the second part is placed below the arch and preferably receives a seal on its upper face (oriented towards the arch). One can also provide a protective plate above the support means and secured to the latter.

 As regards the second fixing means, they advantageously include fixing lugs secured to the second ends of the profiles and terminated by first formally cooperating means, as well as fixing bases secured to the plate while being able to move around. at least partially in the translation plane, and provided with second form cooperation means for cooperating with the first form cooperation means, by defining the plane of rotation.

Thus, the second end of the profile can be rotated in the plane of rotation. The first and second form cooperation means are preferably male and female parts, or vice versa. But other forms can be envisaged as soon as they allow rotation.

 In a preferred embodiment, each fixing base comprises a first part which is immobilized on a structural profile of the plate and which is terminated by second means with form cooperation.

 In a variant of this embodiment, at least some of the mounting bases further comprise at least a second part which is fixed to a structural profile of the sand pit and which is secured to a first part by an axis of rotation, substantially perpendicular to the translation plane. The first part can thus be moved around the axis of rotation, in the translation plane. For the fixing zones located at an angular junction of structural profiles of the plate, it is advantageous to provide not one but two second base parts fixed on two corner profiles of the structure and joined by two axes of rotation at the same first base part. In this way, the base defines a variable angle bracket.

 The invention relates very particularly, but not exclusively, to the roofs of canopies or verandas, and in particular those which have polygonal shapes, in particular hexagonal or octagonal.

 Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended drawings, in which: - Figure 1 is an exploded view of an assembly device according to the invention , relating to the upper part (or ridge), - Figure 2 illustrates the device of Figure 1 once assembled, - Figure 3 is a perspective view, from a first angle of view, of another device assembly according to the invention, relating to the lower part (or sandpit), once assembled, - Figure 4 illustrates the device of Figure 3 once assembled, from a second angle of view, and - Figure 5 is a view exploded view of part of the assembly device illustrated in FIGS. 3 and 4.

 The attached drawings are, for the most part, certain. Consequently, they can not only serve to complete the invention, but also contribute to its definition, if necessary.

 In the following description, reference will be made to a device for assembling the profiles (or rafters) of the roof support structure of a veranda, and more particularly of a "radiant" veranda. Of course, it could be a veranda of another type, such as a Victorian veranda, or more generally a glass roof.

 The rafters 1 are preferably made of a metallic material or an alloy, but, in certain applications, they could also be made of a synthetic material, or using any combination of these materials.

 Reference is first made to FIGS. 1 and 2 to describe a first assembly device according to the invention. Profiles (or rafters) 1 of the

<Desc / Clms Page number 5>

 support structure of a roof extend between an upper part, called ridge, and a lower part called sandpit, so as to support transparent or translucent panels, for example glass.

 In the embodiment illustrated in FIGS. 1 and 2, only the upper fixing means appear making it possible to fix the upper ends 5 of the rafters 1 to the ridge. The lower fixing means, making it possible to secure the lower ends 2 of the rafters 1 to the plate or lower part (generally made up of joined profiles 4 as illustrated in FIG. 4), can therefore be produced according to the different modes known in the prior art , or alternatively according to the mode which will be described later with reference to FIGS. 3 to 5. For example, the lower ends 2 of the rafters 1 can be immobilized using a screw and nut assembly, or an element swivel connection, for example in the form of a hinge, or as mentioned in French patent FR 2,757,891.

 The means for fixing the upper ends 5 of the rafters 1 firstly comprise a multiplicity of independent parts 6, in number equal to the number of rafters of the roof structure. Each part 6 has a first part 7 intended to be secured to the upper end 5 of a chevron 1, for example using a screw. This first part 7 is linked to a second part 8 intended to be mounted (supported) on (by) support means which will be described later.

 In the example illustrated, the first 7 and second 8 parts of a part 6 are in one piece and positioned approximately 900 from one another so as to define an L-shaped square.

 The second part 8 of a part 6 has on its rear face 9 a connecting element 10 (and preferably two, or even more) which defines a passage 11 whose usefulness will appear later.

 Preferably, the connecting element (s) 10 form an integral part of the part 6. This part 6 is therefore preferably

<Desc / Clms Page number 6>

 produced by machining or molding. Furthermore, it is preferably made of a metallic material or an alloy, but, in certain applications, it could also be made of a synthetic material, or using any combination of these materials.

 The upper fixing means of the assembly device also comprise a hoop-type support means 12 which, in the example illustrated in FIGS. 1 and 2, is produced in the form of a half-ring and has a circular cross section. Of course, the arch 12 could have many other forms. It could in particular be a circular or substantially circular ring or else in the form of an ellipse, or else a regular or irregular polygon.

qu'elles puissent se translater sur celui-ci et être entraînées en rotation autour de celui-ci pour définir avec précision la position et l'orientation (ou angle d'inclinaison) de l'extrémité supérieure 5 des chevrons 1. En d'autres termes, l'arceau 12 définit un plan de translation dans lequel peuvent être translatées les pièces 6, et chacune de ses sections transverses définit un plan de rotation perpendiculaire au plan de translation. This arch 12 is intended to receive the parts 6 in such a way

that they can translate thereon and be rotated around it to precisely define the position and orientation (or tilt angle) of the upper end 5 of the rafters 1. In d ' other words, the arch 12 defines a translation plane in which the parts 6 can be translated, and each of its cross sections defines a plane of rotation perpendicular to the translation plane.

 In the example illustrated, the connecting elements 10 define a passage 11 of cylindrical shape and cross section having a substantially equal diameter, by greater value, or diameter of the hoop 12. The hoop is introduced inside the passages 11 of the connecting elements 10 of each part 6 so as to support them, then said parts 6 are translated on the arch 12 so as to be placed opposite the upper ends 5 of the rafters 1.

 The distribution of the different parts 6 on the arch 12 makes it possible to obtain a radiant, star-shaped roof structure.

 The arch 12 could be directly secured to the ridge. But, as illustrated, it is preferable that this arch 12 is secured to a beam 13 using appropriate fixing means, such as for example

<Desc / Clms Page number 7>

 screws. In this case, we define at the ends of the arch two housings provided with internal threads suitable for receiving the screw ends, for example.

 Also preferably, and always as illustrated in Figures 1 and 2, the beam 13 is not secured directly to the ridge. It is in fact preferable to provide an intermediate plate 14, if possible in the form of an L-shaped square, the beam 13 then being secured to the ridge via a substantially vertical part 15 of this plate 14, while the substantially horizontal part 16 of the plate 14 is placed just below the arch 12. In this way, it is possible to insert a seal (not shown in the figures) between the upper face of the horizontal part 16 of the plate 14 and the underside of the arch 12.

 Furthermore, to prevent the arch from deforming, or even sagging, under the weight of the roof, it is particularly advantageous to provide a tie rod 17 whose first (lower) end is secured to the arch 12 while the second (upper) end is secured to the ridge, preferably via the vertical part 15 of the plate 14, for example using a screw 18.

 Preferably, when the arch 12 is in the form of a half-ring (FIGS. 1 and 2), it is advantageous for the lower end of the tie rod 17 to support this arch substantially in its middle.

 When the arch substantially closes on itself, the beam 13 is replaced by several tie rods, for example four, placed in appropriate places. Furthermore, when the arch 12 is closed, it is essential that the connecting elements 10 of the parts 6 are of a different type from those described above. They must indeed have two jaws which are closed on the arch 12 to define the passage 11, for example.

 One can also provide an upper protective plate 19 (or cover) which is placed above the arch 12 to ensure

<Desc / Clms Page number 8>

l'étanchéité extérieure. Un autre joint d'étanchéité peut alors être envisagé pour renforcer l'étanchéité.

external sealing. Another seal can then be envisaged to reinforce the seal.

Preferably, as illustrated in FIG. 1, the cover 19 includes a front orifice 20 allowing the crossing of the lower end of the tie rod 17 and several rear orifices 21 allowing the passage of screws for securing the rear part of the cover 19 to beam 13.

 Reference is now made to FIGS. 3 to 5 to describe another assembly device according to the invention. In this embodiment, only the lower fixing means appear, making it possible to fix the lower ends 2 of the rafters 1 to the ridge. The upper fixing means, making it possible to secure the upper ends 5 of the rafters 1 to the ridge or upper part, can therefore be produced according to the various modes known in the prior art, mentioned previously or else according to the embodiment described with reference to Figures 1 and 2.

 The means for fixing the lower ends 2 of the rafters 1 firstly comprise a multiplicity of fixing bases 22, in number equal to the number of rafters 1 to be assembled, and intended to be secured to the upper surface of the profiles 4 of the sandpit, which define a plane of translation.

 These bases 22 can be moved, at least partially, in this plane of translation. To do this, they comprise at least a first part 23 which can be driven in translation on the profile 4 of the plate to be immobilized there in a chosen position, and terminated by means of cooperation in form 27 whose usefulness will appear later.

 The means for fixing the lower parts 2 of the rafters 1 also include a multiplicity of fixing lugs 28 intended to be secured to the lower ends 2 of the rafters 1, for example by means of screws. These fixing lugs 28 comprise second form cooperation means 29 intended to cooperate with the others

<Desc / Clms Page number 9>

 form cooperation means 27 of the bases 22 to allow rotation of the lower end 2 of the rafter 1 in a plane perpendicular to the plane of translation of the base 22, here consisting of the first part 23.

l'embase 22 tandis que la pièce femelle 29 est portée par la patte de fixation 28. Mais, l'inverse peut être envisagé. Par ailleurs, d'autres moyens à coopération de forme pourraient être envisagés. Preferably, the formally cooperating means 27 and 29 are produced in the form of a male part and a female part. In the example illustrated, the male part 27 is carried by the first part 23 of

the base 22 while the female part 29 is carried by the fixing lug 28. However, the reverse can be envisaged. Furthermore, other means of form cooperation could be envisaged.

 This embodiment of the bases 22 is particularly suitable for the parts of the plate defined by a linear profile, as illustrated in the end parts of FIGS. 3 and 4.

comporte en complément de la première partie 23 au moins une seconde partie 25 destinée à être fixée en une position choisie sur la sablière, par exemple à l'aide d'une vis 24, et solidarisée, à rotation, à une première partie 23, par l'intermédiaire d'un axe de rotation 26. La seconde partie 25 présente, de préférence, une forme générale rectangulaire avec un coin biseauté, pour faciliter son positionnement au niveau d'une jonction angulaire de profilés 4. Grâce à l'axe de rotation 26, ce mode de réalisation procure un autre degré de liberté de déplacement relativement au plan de translation. In some cases, for example when a rafter 1 must be secured to the plate at an angular junction of its profiles 4 (see more particularly Figure 5), it is advantageous that the base 22

comprises, in addition to the first part 23, at least a second part 25 intended to be fixed in a chosen position on the plate, for example using a screw 24, and secured, in rotation, to a first part 23, by means of an axis of rotation 26. The second part 25 preferably has a generally rectangular shape with a bevelled corner, to facilitate its positioning at the level of an angular junction of profiles 4. Thanks to the axis of rotation 26, this embodiment provides another degree of freedom of movement relative to the translation plane.

 As illustrated in FIGS. 3 to 5, it is even more advantageous to provide bases provided with two second parts 25 so as to constitute a square with variable angle. One of the second parts 25 is secured to one of the profiles 4 of the angular junction, the other second part 25 being secured to the other profile 4 of this angular junction, the two second parts 25 being also linked to one

<Desc / Clms Page number 10>

 first part 23 by means of two axes of rotation 24.

un matériau synthétique, ou à l'aide de toute association de ces matériaux. The fixing bases 22 and the fixing lugs 28 are preferably made of a metallic material or an alloy, but, in certain applications, they could also be made in

a synthetic material, or using any combination of these materials.

As indicated above, the assembly device according to the invention can relate to both the ridge and the sandpit. In this case, it consists, for the upper part, of the fixing means described with reference to FIGS. 1 and 2 and, for the lower part, of the fixing means described in FIGS. 3 to 5.

l'orientation de la bissectrice de l'angle intérieur formé par les parois de la véranda, grâce au réglage angulaire de la pièce de fixation autour de l'arceau, pour la partie haute, et au réglage angulaire de la patte de fixation, pour la partie basse. Thanks to the invention, the high and low articulation elements which support the rafters can take a chosen slope angle or different slope angles. The rigid assembly consisting of a rafter, a high joint and a low joint can also take

the orientation of the bisector of the internal angle formed by the walls of the veranda, thanks to the angular adjustment of the fixing piece around the arch, for the upper part, and to the angular adjustment of the fixing tab, for the lower part.

 The devices according to the invention are particularly suitable for canopies (or verandas) whose angle bisectors, formed by the walls, pass through the central axis of said canopy (or veranda). This is particularly the case of hexagonal or octagonal type structures. In situations where the bisectors do not pass through the central axis of the veranda (or canopy), that is to say verandas (or canopies) at any angle, the invention is also suitable by virtue of the articulation of the base (angle at variable angle) at the lower part.

 In other words, the invention is suitable for all canopies or verandas, whether hexagonal or octagonal, as well as for polygons having unequal sides.

 The invention is not limited to the embodiments of the device,

 installation and process described above, only by way of example, but it encompasses all the variants that those skilled in the art may envisage within the framework of the claims below.
