Description

The present invention relates to a safety railing post and a safety railing equipped with several such posts. Safety guardrails are generally present on roof terraces of buildings to provide protection for falls from a height of persons, such as workers having to repair the roof. Each railing is installed all along the edge or parapet of the terrace and includes posts connected in parallel to each other by transverse rails forming safety rails. The posts and their slats are either fixed to the parapet to protect from falls from height, or installed near the acroterium being regularly spaced along the acroterium. However, the disadvantage of such railings is that they are visible from the outside of the buildings on the roof terraces of which the railings are installed and can therefore affect the overall aesthetic appearance of these buildings . The object of the present invention is to overcome the above disadvantage by proposing a guard rail post and railing solution comprising a plurality of such posts that are normally invisible from the outside of the terraced roof of a roof. building on which they are installed while ensuring the safety of persons having to carry out repair work on the roof terrace of this building.

For this purpose, according to the invention, the safety rail post, which comprises a fixed amount of a support, is characterized in that the amount is articulated to the support to switch between a standing position and a supine position parallel or inclined to the ground including a roof terrace of a building and is extended opposite its articulation to the support by a curved portion such that lying supine it departs from the ground. Preferably, the bent part of the upright comprises two straight elements extending the upright, a first element connected to the upright is inclined relative to the upright and a second element extending the first element while being inclined relative to the first element in the same direction as this latest.

Preferably, the support of the upright comprises a stirrup between the parallel walls of which is mounted articulated the corresponding end portion of the amount that can be locked or locked to the support in upright or recumbent position.

Advantageously, the means of articulation of the upright to the support stirrup comprise two coaxial axes integral transversely of the end of the upright on either side of the latter and engaged through two lights of the two parallel walls of the support bracket extending parallel to the connecting wall of these two parallel walls and the locking means comprise first two other coaxial axes integral transversely of the end portion of the amount on either side of the latter and engageable in two notches formed in the upper edges of the two parallel walls above and away from the two lumens thereof to lock the upright to its upright position, and on the other hand a bar secured to both walls parallel of the support bracket perpendicularly thereto and on which may support the end portion of the upright of the latter for the bloq to this position. According to a first embodiment, the support of the upright is integral with a Z-shaped tab for fixing the post to an acroterium bordering the roof terrace of the building.

According to a second variant embodiment, the support of the upright is integral with a base forming part of a self-supporting structure of the post that can be placed near an acroterium bordering the roof terrace of the building. According to a third variant embodiment, the support of the upright can be fixed directly to an acroterium bordering the roof terrace of the building. The invention also relates to a safety railing installed on a roof terrace of a building along a parapet bordering the roof terrace, comprising posts connected in parallel to each other by transverse rails, and which is characterized in that each post is as previously defined. Finally, the invention relates to a roof terrace of a building bordered by a parapet, characterized in that it comprises several guardrails security, each as defined above, and which are attached to the acroterium along the one or installed near the acroterium along it. The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows with reference to the accompanying drawings given solely by way of example illustrating several embodiments. of the invention and in which: - Figure 1 is a perspective view of a portion of a roof terrace of a building defined by a parapet to which is fixed a safety railing according to the invention, occupying a standing security position; FIG. 2 is a perspective view showing the safety railing of FIG. 1 in an invisible supine position from the outside of the terrace roof of the building; Figure 3 is a perspective view of several safety railings integral with self-supporting structures installed near an acroterium bordering a roof terrace of a building with each guardrail occupying a standing safety position; - Figure 4 is a perspective view of a safety post of a self-supporting structure of Figure 3 and occupying its upright position; - Figure 5 is a perspective view showing the safety post of Figure 4 in supine position; FIG. 6 is a perspective view of a safety guard post standing in a standing position and capable of being fastened by means of a Z-tab to an acroterium bordering the terrace roof of a building; and Fig. 7 is a perspective view showing the railing post of Fig. 6 in the supine position. With reference to FIGS. 1 and 2, the reference 1 designates a safety railing fixed to the internal face 2a of a parapet 2 bordering a roof terrace of a building, such as a building, and whose floor The security railing 1 comprises a plurality of posts 4, in this case two in number, which are connected in parallel to one another by transverse rails 5. As shown, three rails 5 are arranged transversely between two consecutive posts 4 being regularly spaced from the rail 5 secured to the end of the posts 4 opposite their attachment to the acroterion 2. Each rail 5 may be constituted by a steel tube passing through the 4 posts that can be constituted by oblong steel tubes.

According to the invention, the safety railing 1 is articulated to the acroterion 2 to switch between a standing safety position shown in Figure 1 and a recumbent position parallel or inclined to the ground 3 of the roof terrace of the building as shown in Figure 2. In this recumbent position, the railing 4 is made completely invisible from the outside of the building so as not to affect the overall aesthetic appearance of the building. In case of intervention of people on the roof terrace of the building for a repair thereof, the safety railing 1 is then raised from its folded position of Figure 2 to its standing safety position of In addition, each post 4 of a railing 1 can be locked or locked in its upright position or in its folded position towards the ground 3 by locking means which will be defined later. Each post 4 of the railing 1 comprises an upright 6 pivotally mounted to a support 7 integral with the inner face 2a of the parapet 2 and which is extended opposite the support 7 by a bent portion 8 configuring the post 4 approximately in a stick. The centered portion 8 of each post 4, when the safety railing 1 occupies its folded position of Figure 2, extends above the ground 3 of the roof terrace away or flaring from the ground and when the safety railing 1 occupies its standing safety position of FIG. 1, the upright 6 of each post 4 extends vertically from the parapet 2 and the arched portion 8 projects from the upright 6 above acrotere 2 outside of it, that is to say outside the roof terrace of the building. The arched portion 8 of each post 4 comprises two straight elements extending the upright 6 of the post 4, and comprising a first element 9 connected to the upright 6 being inclined relative to the latter and a second element 10 extending the first element 9 by being inclined relative to the first element in the same sense as the latter. The amount 6 and the two elements 9,10 are arranged in the same plane. The angles of inclination respectively defined between the first element 9 and the upright 5 of a post 4 and the first and second elements 9, 10 are such that the second element 10 may be substantially perpendicular to the upright 5. The support 7 of the upright 6 of each post 4 is constituted by a stirrup piece between the parallel walls 11 of which is pivotally mounted the corresponding end portion of the upright 6. The wall 12 connecting the parallel walls 11 of the stirrup piece 7 is fixed by any suitable means, not shown, such as for example screws, to the vertical inner face 2a of the acroterium 2 so that the two walls 11 occupy a vertical position. The hinge means of the upright 6 of a post 4 to the stirrup piece 7 comprise two coaxial axes 13 integral transversely with the end of the upright 6 on either side of the latter and which are engaged through respectively two lumens 14 formed in the two parallel walls 11 of the stirrup piece 7, the two lumens 14 extending parallel to the connecting wall 12 of the two side walls 11 of the part 7, that is to say according to a vertical direction. Thus, the two lights 14 not only allow the axes 13 to pivot the corresponding amount 6 of a post 4 between the upright and recumbent position of the post, but also the displacement in translation of the axes 13 along the lights 14 when pivoting the upright 6 from a standing position to its supine position and vice versa, as will be seen later. The means for locking a post 4 to the stirrup piece 7 in its upright position comprise two other coaxial axes 15 secured transversely to the end portion of the upright 6 on either side of the latter and being able to engage respectively in two indentations 16 formed in the upper edges 11a of the two side walls 11 of the stirrup piece 7 above and at a distance from the two slots 14 of the walls 11. Thus, in the standing position of the posts 4, the axes 15 housed in the notches 16 cooperate with the axes 13 housed in the slots 14 in lower parts thereof to block the post 4 at this position. The means for locking the post 4 to the stirrup piece 7 in its supine position comprises a bar 17 secured to the two side walls 11 of the stirrup piece 7 perpendicular thereto and on which the part of end of the upright 6 in the supine position of the latter. At this position, the pivot axes 13 of the upright 6 of the post 4 are supported at the upper ends of the two slots 14 of the stirrup piece 7 so as to block the post 4 resting by gravity on the bar 17 in its supine position. As shown, the bar 17 is fixed, for example by welding, to the vertical edges of the two walls 11. Normally, each guardrail 1 occupies the position folded towards the ground 3 of the roof terrace of the building so as to be completely invisible from outside the building so as not to detract from the overall aesthetic appearance of this building. In this folded position, the arched conformation of the posts 4 of the guardrail flaring from the ground 3 and the presence of the rails 5 between posts 4 prevent any operator present on the roof terrace of the building to approach the acroterium 2 thus ensuring a deterrent security function. Indeed, the railing forms a curved barrier difficult to cross, the smooth spread over the curvature of the guard rail protruding from the ground and on the latter making the barrier difficult to step over and making it difficult to support the feet beyond the barrier near the acroterium. When the operator has to carry out repair work on the terrace of the building, he pivots by raising the railing 1 relative to the stirrup pieces 7 towards the standing position of the railing, which causes on the one hand the displacement pivot axes 13 to the lower ends of the respective apertures 14 and the automatic engagement of the locking pins 15 in their respective recesses 16 of the side walls 11 of the stirrup parts 7 to lock the guardrail in its upright position. In this way, the operator can work safely on the terrace of the building. Once the repair work has been carried out, the operator pulls upwards on each railing 1 so as to disengage the locking pins 15 from their respective recesses 16 and then pivots the railing 1 towards the ground 3 by the pivot axes 13 which move upwardly in the slots 14 to bring the end portions of the uprights 6 resting on the corresponding bars 17 to block the guardrail at its outer invisible position of the building by pressing the pins 13 at the upper ends of the slots 14. FIG. 3 represents an embodiment variant according to which several guardrails 1 occupying their standing safety position, each identical to the guardrail 1 of FIGS. 1 and 2, are pivotally mounted by their uprights 6 respectively to stirrup parts 7 identical to the stirrup parts 7 of Figures 1 and 2. In this way, it is useless to describe the differences again. 1 and the manner in which each upright 5 is articulated to a corresponding stirrup piece 7 to ensure the tilting of the guardrails 1 between their standing safety position of FIG. 3 and their folded or reclined position , not shown, so that these railings 1 are invisible from outside the building.

The differences between the variant embodiment of FIG. 3 and that of FIGS. 1 and 2 reside in the fact that each stirrup piece 7 supporting an upright 6 of post 4 is not integral with the internal face 2a of the acrotere 2, but is part of a self-supporting structure 18 resting on the floor 3 of the terrace of the building so that each stirrup piece 7 is located near the acroterion 2 opposite its inner face 2a.

Figures 4 to 5 show in more detail a self-supporting structure associated with each safety post 4. Thus, each stirrup piece 7 is fixed, for example by welding, perpendicularly to a base plate 19 resting on the ground 3 and a part protruding from the part 7 opposite the bar 17 can bear down the inner face 2a of the acroterion 2 to position the stirrup piece 7 opposite the inner face 2a.

The base plate 19 is part of the self-supporting structure 18 which further comprises a rigid bar 20 fixed, for example by welding, on the base plate 19 and extending behind the stirrup piece 7 substantially in the same vertical plane containing the corresponding post 4 and a length substantially identical to the length of the post 4 when it occupies the supine position of Figure 5. The self-supporting structure 18 finally comprises a heavy body 21 of metal or in concrete fixed to the end of the bar 20 opposite the base plate 19. The heavy body 21 may consist of several juxtaposed elements 22 to ensure sufficient weight allowing the structure 18 to support without moving each FIG. 3 shows that each railing 1 has three parallel posts 4 connected to each other by the rails 5 and that two adjacent posts 4 of two consecutive guardrails 1 are mounted articulately. respectively two stirrup-shaped parts 7 integral with the same base plate 19 of a self-supporting structure 18. Figures 6 and 7 show a third embodiment of a post 4 forming part of a guard safety body identical to each safety railing 1 of Figures 1 to 5 and which can pivot by its amount 5 in a stirrup part 7 identical to each stirrup part 7 described in the other two variants. The difference between this third embodiment and the other two lies in the attachment of each stirrup piece 7 supporting a post 4 to the acroterion 2 by means of a Z-shaped tab 23, one of which flat branches 24 is fixed, for example by a screw not shown, on the flat horizontal face 2b of the acroterion 2 and the other leg 25 vertically carries the stirrup piece 7 which is fixed, for example by welding, on the branch 25.

Each safety railing 1 of the invention can thus be hidden by tilting above the floor of the roof terrace of a building to not detract from the overall aesthetic appearance of the building. In the reclining position of the railing, the end rails 5 of the posts 4 are at a determined distance from the acroterium, for example about 0.80 meters, and at a determined height above the ground roof terraces as they provide a deterrent effect anyone on the terrace to approach the acroterium for security reasons. When an operator has to carry out repair work on the terrace of the building, it is enough for him to tilt each railing from its supine position to its standing security position so that it can carry out these works in complete safety. Once the repair work is complete, it is sufficient to fold each guardrail back to its supine position above the floor of the terrace to conceal each guardrail from outside the building. The means for tilting each railing between its folded or reclining and standing positions are of an extremely simple and inexpensive structure.
