Description

Photovoltaic and / or thermogenic element of guardrails and guardrails made up of such elements. The invention relates to a photovoltaic and / or thermogenic panel for mounting guardrails, particularly at the periphery of non-accessible or technical roof terraces, for protection against falls. It also applies to railings consisting of a set of these panels butted one after the other. Railings are most often constituted by spaced vertical uprights or posts connected by parallel horizontal rails comprising at least one upper rail called "handrail" and an intermediate rail. Official requirements generally specify the conditions to be met by guardrails which, with regard to the equipment of flat roofs, are generally fixed on the roofs of these, close to the acroterium. For example, according to French regulations, the height of the handrail of horizontal railings must be between 1000 mm and 1100 mm from the platform of roofs or roof terraces. On the other hand, the free space between the handrail and the intermediate rail, and between the intermediate rail and the implantation platform must be less than or equal to 500 mm. In the case of railings inclined amounts this distance is measured in the plane of the railing, the intermediate rail to be halfway up the latter. Recently, some installers of photovoltaic panels on rooftop terraces have undertaken to fix these panels on the railing ensuring the protection of people against the risk of falling. It is understood that such a method of installation of photovoltaic panels requires the existence or the establishment of a railing support panels and the use of a specific hardware to fix said panels on the guardrail, this fixing represents a long and expensive operation. The compliance of photovoltaic installations with the official requirements specifying that photovoltaic panels must constitute the main safety elements of the railing entails the same disadvantages. The invention particularly aims at the realization of a photovoltaic panel and / or thermogenic guardrail and guardrail constituted by a set of such panels abutted one after the other and constituting the main security elements of said bodyguard. According to the invention, this object is achieved by means of a photovoltaic and / or solar panel surrounded by a rigid frame, said panel being particularly remarkable in that one of the sides of this frame is rigidly secured to a section of handrail having two ends arranged to allow its junction with the handrail section of the adjacent guardrail element (s). According to an advantageous embodiment, the section of handrail has a tubular shape and it comprises a through axial passage. According to a preferred embodiment, the section of handrail is formed in one piece with the side of the frame to which it is attached. According to another embodiment, the section of handrail is attached to the concerned side of the frame by any appropriate means known per se, for example by screwing or welding. According to one embodiment applicable to photovoltaic and / or thermogenic elements of rectangular shape, the section of handrail is attached to one of the long sides of the rigid peripheral frame of said elements. According to another embodiment, the section of current hand is secured to one of the short sides of the frame.

According to another characteristic arrangement, the section of handrail has a length at least equal to, or preferably slightly greater than that of the side of the frame to which it is attached. The photovoltaic and / or solar railing according to the invention is remarkable in that it consists of a set of photovoltaic and / or thermogenic panels provided with a peripheral rigid frame whose upper side or "high side" is rigidly secured to a section of handrail. The sections of handrail of said panels are abutted one after the other, so as to constitute a handrail without continuity solution. According to another characteristic arrangement, the successive sections of the handrail are connected by a connecting means. According to one embodiment, the sections of handrail comprise a through axial passage, for example of cylindrical or quadrangular section, and said sections of handrail are connected by means of a tubular sleeve of complementary section or a part connection engaged in the adjacent ends of two adjacent sections of handrail. According to another embodiment, the lower part of the section of handrail fulfilling the function of essential element of resistance to the accidental crossing of the guardrail is constituted by a profile having a U-section whose interior space is closed by a hood or lid. According to one embodiment, the connection sleeves are rigidly fixed in the ends of handrail sections by means of screws. According to another characteristic arrangement, the photovoltaic and / or thermogenic railing comprises posts or legs making it possible to connect the side of the frame provided with a section of handrail and the platform for the implantation of said guardrail.

According to another characteristic arrangement, when the photovoltaic panels have a height greater than 1000 mm or 1100 mm in the vertical position, or when, as a result of the arrangement of their base remote from the implantation surface, said panels are fixed on the platform with an inclination of between 20 ° and 60 °, for example with an inclination of the order of 30 °, so that the handrail is at a height between 1000 mm and 1100 mm from said plate in such a way that the guardrails made of such panels comply with the regulatory requirements.

According to another characteristic arrangement, the bottom side of the frame intended to constitute the base of the photovoltaic and / or thermogenic panel, is fixed on the platform, close to the acroterium, by any appropriate mechanical means of anchoring known per se , for example on the top of a post and / or on a fixing rail, anchored in said platform.

The invention makes it possible to provide a robust and effective barrier against the risk of falling without the need to install a traditional guardrail; this results in a significant simplification of assembly operations and a reduction in installation costs.

These drawings are described to describe two advantageous exemplary embodiments, although in no way limiting, photovoltaic and / or thermogenic guardrail elements and guardrails made up of such elements, according to the invention. This being more particularly advantageous in its application to the production of guardrails made of photovoltaic panels, reference is made hereinafter to such panels to simplify the description of the railing elements and the guardrails. bodies made up of such elements. It should be noted, however, that the railing elements may be constituted by solar collectors or also by mixed photovoltaic / solar panels (for example WO-2008/114248, EP-2 262 004). According to a first exemplary embodiment illustrated in FIGS. 1a to 10a, the guardrail element 1A mainly comprises a photovoltaic module 2 enclosing the electrical energy generating components and a rigid frame 3 surrounding said module 2. This module and the surrounding frame has a quadrangular shape, usually rectangular, in a manner known per se. The border of the photovoltaic module is, for example, embedded and maintained in a groove that the different sides of the frame 3 present, as shown more particularly in FIG. 3a. The frame 3 can be executed in any material having the strength and rigidity necessary for its function.

It may, for example, be made of aluminum, or aluminum alloy, or stainless steel, etc. According to a first important feature of the invention, one of the sides of the frame 3 is rigidly secured to a section of handrail 5 4A. The section of handrail 4A or 4B can be attached to one of the short side of the frame 3 (Figure 4a or 4b), or to one of the long sides of said frames (Figure 5a or 5b). In the composition of a railing made according to the invention, the side of the frame provided with the handrail portion 4A or 4B occupies a raised position relative to the opposite side parallel to the previous one. For this reason, the side of the frame provided with the section of handrail is called "high side" in the remainder of this presentation, while the opposite side of said frame is called "low side", regardless of the type of element " vertical "(Figure 4a and 4b) or 15" horizontal "(Figure 5a and 5b) The section of handrail 4A is preferably formed in one piece with the upper side 3A of the frame 3, as shown more particularly in Figures 3a and 3b. According to another embodiment the handrail section 4A 20 could however be attached to the upper side of the frame by any suitable fastening means known per se, for example by screwing or welding. The opposite ends of the handrail section 4A, 4B are arranged or shaped to allow their assembly with the handrail section of the element or adjacent guardrail elements (s). The handrail portion 4A has a length at least equal to the length of the upper side 3A of the frame 3 to which it is attached or, preferably, a length slightly greater than that of said side 3A.

According to the embodiment shown in Figures 1 to 10a, the section of handrail 4A has a cylindrical shape and it comprises an axial passage or longitudinal through 5A of circular section. In this case, the section of handrail 4A may consist of two coaxial cylinders 4a, 4b assembled by radial spacers 4c. The axis of the handrail section 4A can be shifted towards the rear face of the frame 3 relative to the median plane PP of the latter. FIGS. 1b to 10b show a second embodiment of the photovoltaic element of railing 1B which differs from that just described in that the section of handrail 4B has a parallelepipedal shape of square or rectangular section and has a through passage 5B of square or rectangular section. The lower part 4d of this section of handrail fulfilling the function of essential element of resistance to accidental crossing of the railing, may be constituted by a robust section having a U-section whose interior space is closed by a hood 4e fixed by clipping or otherwise on the upper edge of the wings of this section which have longitudinal grooves in which are engaged reentrant fins which is laterally provided said hood (see in particular Figure 7b).

The photovoltaic elements of guardrails can have variable dimensions, for example an average dimension of 900 mm × 1600 mm. According to the dimensions of the photovoltaic elements of guardrails, when they have a rectangular shape, and depending on the choice of their positioning in the photovoltaic installation, the section of handrail can be provided on a small side (Figures 4a and 4b). ) or on a long side (FIGS. 5a and 5b) of the frame of the photovoltaic elements of guardrails 1A or 1B, as indicated previously.

The photovoltaic railing according to the invention consists of a set of photovoltaic elements of guardrails 1A, 1B formed of photovoltaic panels 2 provided with a rigid peripheral frame 3, one side of which is provided with a section of handrail 4A or 4B.

The railing elements 1A and 1B are arranged side by side and their handrail portions 4A, 4B are arranged in succession and are abutted one after the other so as to constitute a handrail 4 without continuity solution. The successive sections 4A or 4B of the handrail 4 are connected by a connecting means. This connecting means may be constituted by a connecting piece, of elongate shape, engaged and locked in the adjacent ends of two adjacent sections 4A or 4B of handrail. According to the embodiment illustrated in FIGS. 8a to 10a, the connecting piece is constituted by a sleeve 6A having a cylindrical shape and this connecting sleeve is engaged, without any appreciable play, in the axial passages 5A of the adjacent sections of handrail 4A. According to FIGS. 8b to 10b, the connecting piece 6B has a parallelepipedal shape and is engaged in the adjacent ends of the longitudinal through-passages 5B that the adjoining sections of handrail 4B present. In this case, the connecting piece 6B is housed in the bottom of the U-shaped section constituting the lower part of the handrail section and can be fixed rigidly in the adjacent ends of adjacent handrail sections 4B, by means of screws. 7 or otherwise. The photovoltaic railing further comprises posts 8 whose apex is fixed or arranged to be fixed to the handrail sections of the railing elements and for connecting the upper edge of said elements to the implantation surface T.

According to FIG. 7a, the top of the posts 8 comprises a concave cradle 9 in which the cylindrical section 4A of handrail 4 rests. According to FIG. 7b, the top of the posts 8 is provided with a support wall 10 on which rests the parallelepipedal section 4B of handrail 4.

Fixing the sections of handrail 4B on the top of the posts 8 constituted by the support wall 10 can be achieved by means of screws 7 ensuring the assembly of the handrail sections and screwing into said support wall. The lower part of the photovoltaic guardrail elements according to the invention can be fixed on the implantation surface T by any appropriate mechanical means of anchoring known per se, for example on a fastening rail itself anchored in said surface . For example, according to FIGS. 1a, 2a, 1b, 2b and 11, the railing is shown installed on a roof terrace T near the parapet A and the railing elements are fixed to the roof this roof-terrace by means of a post 12 and a mechanical assembly system 13 known per se and consisting of complementary members equipping respectively the lower part of the rear face of the frames 3 and the top of the posts 12. The base of these posts can be fixed on a fixing rail (not shown) itself anchored in the roof of the roof terrace T or other implantation surface. As shown in FIGS. 1a, 2a and 1b, 2b, the photovoltaic guardrail elements can be installed with an inclination of between 20 ° and 60 °, for example with an inclination of 30 °.

With this arrangement, it is possible to use railing elements of a height greater than that which is imposed for the height to which the handrail must be situated (1000 mm to 1100 mm), or to install railing elements of lower height but positioned at a distance from the implantation surface T, as illustrated for example in Figures 2a and 2b.
