Description

RIGID BODY GUARD WITH ADJUSTABLE FIXINGS

The present invention relates to a rigid guardrail terrace or roof to delimit an accessible space on it. The guardrail is particularly intended for temporary use, the time of the realization of a construction site on the roof or on the terrace, such as to renovate the roof or the roof of said roof or said terrace.

However, it may be possible to envisage a longer-term or even permanent use for installation on terraces of buildings on which air-conditioners or air-handling units are generally arranged, which require preventive maintenance and therefore a possibility of access. to machines safely.

Known railings generally consist of posts on which are fixed safety barriers. The posts are secured to the roof or the terrace either by nailing or by direct screwing on the roof or terrace, or on the upper end of the walls of the building, or by means of intermediate anchors, able to receive said posts, themselves fixed on the roof or the terrace.

The security barrier consists mainly of a grid or a rigid panel that prevents the passage of objects or people through it. The grid or panel is secured to a rigid frame which is fixed on the posts; the frame is fixed either by bolting on the posts or by means of anchors which are fixed on the frame.

Such a design requires a rigorous and precise installation of the posts so that their position corresponds to that of the anchor points of the barrier. However, it is possible that the configuration of the roof or terrace does not allow to position the posts at the desired location; it is therefore appropriate to adapt or modify the fixing of the barrier, for example by means of additional anchors. Certain railings, such as that disclosed in the patent application GB 2 398 100, allow to adapt the points of attachment of the barrier depending on the position of the posts which are themselves provided with anchor points fixing by hanging through the grid; these anchor points are of a more or less complex technical design which considerably increases the cost of manufacturing the posts. Other similar installations have simpler design anchors that grip the grid or panel by screwing or bolting; they therefore require the use of tools to carry out the intervention which is carried out according to a variable duration depending essentially on the configuration of the roof or terrace.

Also known is US Pat. No. 3,863,899 which discloses a removable railing consisting of a rigid frame fixed on posts by means of anchoring parts; the anchoring pieces slide along the upper part of the rigid frame to adapt their position to that of the posts. Such a guardrail can not be used on roofs that have a slope and require that the barrier is at least screened or completely closed, to prevent the fall of an object or a person who could slip on said roof; however, the establishment of a grid or a panel on the rigid frame of the railing such as that object of US Patent 3,863,899 is not compatible with the anchoring means which must be able to slide to adapt their position and bring them to the right of the posts.

The present invention aims to overcome the existing disadvantages by providing a rigid railing roof or terrace whose barrier is completely closed by a grid or a rigid panel, having removable and sliding anchoring means, whose position can adapt according to that of the posts on which they are fixed.

For this purpose, the invention proposes a guardrail rigid roof or terrace for delimiting an accessible space and preventing the fall of objects or persons, comprising at least two posts, fixed at the edge of the roof or terrace, on which is fixed a solid rigid barrier and / or meshed by means of anchoring carriages, the guardrail being remarkable in that it comprises an anchor bar integral with the rigid barrier, and located in a plane offset from the plane of said barrier, on which are mounted sliding the anchor carriages to adapt their position to that of the posts.

It is understood that such a design advantageously makes it possible to equip the railing with a barrier completely closed by a grid or a rigid panel, thereby guaranteeing optimum safety, perfectly suited to use on roofs, while allowing adapt the position of the anchors according to the position of the posts, which depends mainly on the configuration of the roof.

Other advantages and features of the present invention will emerge more clearly on reading the following description, which is based on a nonlimiting example of the invention with reference to the appended drawings, among which:

FIG. 1 represents an overall view, from the side, of the railing object of the present invention, installed on a roof,

- Figure 2 shows a front view of the barrier.

The railing 1 object of the present invention is intended for use on roofs or terraces 3, as shown in Figure 1; it consists of at least two posts 5 fixed for example in limit 7 of the roof 3 or the terrace by means of anchoring feet 9. The anchoring feet 9 are, in a preferred and nonlimiting mode, fixed on rafters when used on a roof 3; while on a terrace, they will be fixed on the periphery of it or on the upper limit of the walls of the building. Their position therefore defines that of the posts and depends mainly on the configuration of the roof 3 to which they are attached.

The anchoring foot 9 consists of a first end 11 secured to the roof 3 or the deck by screwing or nailing, or any other equivalent means, and a second end 13 which receives by insertion or by fitting the low end 15 of the post 5. In a preferred and nonlimiting mode, the two ends 11 and 13 are inclined relative to each other at an angle α which is a function of the inclination of the support (roof or terrace) on which the anchoring foot 9 is fixed, and which makes it possible to obtain an almost vertical position of the post when it is inserted or fitted on the second end 13. For a terrace, for example, the angle α will preferably be ninety degree (90 °), which corresponds to an anchoring foot 9 with its two ends 11 and 13 arranged at right angles.

The posts 5 are in a preferred mode of circular or square section; we can however consider posts of any section, such as rectangular or triangular. They allow the attachment and maintenance of a barrier 17 in a position substantially identical to theirs, namely a more or less vertical position, as shown in Figure 1.

Figure 2 shows barrier 17; it consists, in a preferred and non-limiting mode, of a grid panel 19 and / or solid, reinforced by a rigid frame 21 constituting the frame of said barrier 17. The barrier 17 is fixed on at least two posts by means of anchoring carriages 23, each post 5 receiving at least one anchoring carriage 23 of a barrier 17.

The anchoring carriages 23 consist of two parts 25 and 27. The part 25 serves to fix the barrier 17 on a post 5; it is preferably hollow, and of shape and section adapted to those of the post 5, which advantageously allows it to slide on said post insertion from its upper end 29. However, we can consider a piece 25 of circular section regardless of the shape of the post 5. We can also consider, in a variant, a piece 25 hook-shaped insert at the hollow end of the post 5.

The piece 27 is secured to the barrier 17 and movable thereon; indeed, the piece 27 is slidably mounted on the barrier 17 and can translate along it. This sliding assembly allows to position the piece 25, integral with the piece 27, opposite the post 5, and then to insert it thereon.

The barrier comprises for this purpose a rigid bar 31 which is remarkable in that it lies in an offset plane, and preferably parallel to the plane of the solid and / or screen barrier 17, said bar 31 receiving at least two pieces 27 of two anchoring carriages 23. The part 27 is hollow, and of shape and section adapted to those of the bar 31 so that it can slide on said bar and thus allow to change its position on the barrier 17 in order to have the part 25 facing the post 5. The offset between the plane of the bar 31 and that of the barrier 17 advantageously slides the part 27 on said bar 31 without any resistance or friction on the panel 19 mesh and / or full of said barrier 17.

In a preferred mode of design, the bar 31 is of identical length to that of the barrier 17 in order to optimize the range of adjustment of the position of the anchoring carriages 23 on the barrier 17, and to allow a greater variation of the position of the posts 5 on the roof 3; the bar is fixed for this purpose by its ends 33 and 35 on the lateral edges 37 and 39 of the barrier 17. The ends 33 and 35 may for example have a square shape, not shown in the accompanying figures, to create an offset of the bar 31 with respect to the plane of the barrier 17.

The pieces 25 and 27 of the anchoring carriage 23 are of preferably, fixed relative to each other and the axis of the part 25 is perpendicular to that of the part 27; the carriage 23 is obtained, for example, by welding between the two parts 25 and 27, which allows to design for a minimal manufacturing cost. This design assumes, however, that the posts 5 are all arranged perfectly parallel to each other, for example vertically, in order to prevent the locking of the anchoring carriages 23, by bracing, when they are placed on the posts 5. It is possible, according to a variant, to provide a hinge of the pivot connection type between the part 25 and the part 27 making it possible to articulate the part 25 and to arrange its axis in the same position as that of the post 5, that is, that is to say, parallel, thus making it possible to compensate for the defects of parallelism between the posts, and thus to fix perfectly, without it jamming, the barrier 17 on the posts 5 by guaranteeing a proper positioning of the barrier 17 resting on the roof 3. In a preferred and non-limiting embodiment as shown in Figure 2, the barrier 17 consists of a rigid frame 21 completely closed by a rigid panel 19, the extr emitted low 41 is full, and whose high end 43 is screened. Such a design advantageously makes it possible to lighten the barrier and to facilitate its handling, and then to prevent any possibility of passage of an object through said barrier 17, which object could possibly slide on the inclined roof 3.

Another preferred mode is to achieve all the elements of the railing with a treated material, resistant to corrosion, such as galvanized steel. Other implementations within the reach of the skilled person may be considered, without departing from the scope of the present invention.
