First of all, reference will be made to FIGS. 1 to 19 relating to a self-supporting safety guard bearing the reference 1 and used in particular on a roof terrace of a building, the floor of which is referenced in 2. The guard The self-supporting safety body 1 comprises a plurality of guardrail posts 3, only three of which are shown in FIGS. 1 and 3, and which are connected in parallel to one another by two smooth hand rails 4 extending horizontally. relative to the ground 2 being fixed to the upper and intermediate portions of the railing posts 3. Thus, the two rails 4 extend transversely to the guardrail posts 3 which are regularly spaced from each other. The guard posts 3 rest on the ground by means of plates or support bases 5 in the general shape of rectangular plates. The self-supporting safety railing 1 further comprises parallel and horizontal offset arms 6 whose ends on the same side are connected to the lower end portions of the guard posts 3, and counterweights 7 resting. on the ground 2 being fixed to the end portions of the offset arms 6 opposite to the end portions connected to the railing posts 3.

The counterweights 7 allow the guard posts 3 to be held on the ground 2 at their standing service position to which the posts 3 can be vertical or inclined, as will be seen later. Each guard post 3 and each associated offset arm 6 are arranged in the same vertical plane on the ground 2.

The different sets with guard posts 3, offset arm 6 and counterweight 7 are regularly spaced from one another and the support plates 5 of the railing posts 3 are arranged along a parapet 8 bordering on the least part of the outer periphery of the floor 2 of the roof terrace of the building with the offset arms 6 extending perpendicularly from the acroterium 8 and the railing posts 3 arranged in front of the vertical wall of the acroterium 8 considering a person located on the floor 2 of the roof terrace of the building.

The structure of each counterweight 7 and its method of attachment to the end portion of the corresponding offset arm 6 are described in document FR 2 960 249 in the name of the applicant and will not be detailed again.

According to the invention, each of the guardrail posts 3 is made from a folded sheet having a U-shaped cross section all along the post, the folded sheet preferably being a steel sheet. In the standing safety position of each guard post 3, the wall 3a forming the connecting core of the two parallel side walls 3b of the U-shaped 10 of this post is arranged facing the acroterium 8 and each guard post 3 at its lower end portion fixed to a waiting part 9 integral with the corresponding support plate 5. Each waiting part 9 is constituted by a rectangular base block projecting from its support plate 5 and having two 15 flat side walls perpendicular to the plate 5 and two end walls inclined from the plate 5 converging towards each other to the level of the upper planar face of the block parallel to the plate 5 as shown in FIGS. 5, 7, 13. Figures 9 to 12 show an alternative embodiment of the stirrup-shaped holding part 9, as will be explained later. In addition, each offset arm 6 is also made from a folded sheet, preferably steel, having a U-shaped cross section along this arm. Each offset arm 6 rests on the ground 2 so that the wall 6a 25 forming the connecting core of the two parallel side walls 6b of the U of this arm is located above the ground 2 parallel to it with the two parallel walls 6b extending perpendicularly to the ground 2. In other words, the opening of the U of each offset arm 6 opens in front of the ground 2. Each offset arm 6 has its end portion, opposite the counterweight 7, also fixed to the waiting part 9 of the support plate 5 associated with this arm. In the variant embodiment of the self-supporting safety railing 1 of FIGS. 1 to 8, attachment to a waiting part 9 of the lower end portion of the corresponding railing post 3 and the part of the end of the associated offset arm 6 is rigid. To ensure the rigid attachment of the end portions of each guard post 3 and each offset arm 6 to the waiting part 9 of FIGS. 1 to 8, the end portion of the offset arm 6 opposite the counterweight 7 is engaged by its two side walls 6b on either side of the lateral faces of the waiting part 9 so that this end portion overlaps the waiting part 9. Where appropriate, the two side walls 6b of the end portion of the offset arm 6 can exert a pinch force on both side faces of the waiting part 9. Then, the lower end portion of the guard post 3 is engaged on the waiting part 9 so that its core wall 3a is adjacent to the corresponding oblique end face of the part 9 and its two side walls 3b are arranged on each side of the two side walls 6b of the offset arm 6. So, the end part of the offset arm 6 is housed between the two lateral branches 3b of the lower end portion of the guard post 3. Then, fixing members, such as for example screw bolts 10 and nuts 11, in the two present cases are engaged through the side walls 3b of the guard post 3, the side walls 6b of the offset arm 6 and the waiting part 9 to rigidly fix the post 3 and the arm 6 to this room. The two side walls 6b of the end portion of the offset arm 6 comprise three pairs of coaxial bores 12, a first pair 25 located just below the two connecting edges of the core wall 6a to the side walls 6b and serving passing through a screw 10, and two other pairs of holes 12 made in the lower part of the two side walls 6b being offset from each other in height and along these walls to allow the passage in one or the other of these two pairs of the second screw 10 of the fixing bolt. The waiting part 9 has three through holes 9a which respectively face the three pairs of bores 12 of the end portion of the offset arm 6 when this end portion is mounted to overlap on the part of The lower end portion of the guard post 3 comprises two pairs of coaxial bores 13 formed through the two side walls 3b, a first pair of bores 13 being located at a first distance above the edge. lower end of the post 3 near the edges of the two side walls 3b and a second pair of holes 13 located near the lower edges of these side walls 3b being shifted relative to the first pair of holes 13.

Thus, when the guard post 3 and the offset arm 6 occupy their mounting or assembly position to the waiting part 9, the holes 13 of the first pair are coaxial with the bores 12 of the offset arm. 6 located near its two edges and the upper bore 9a of the waiting part 9 for the passage of the upper screw 10 by considering Figure 5 and the two lower holes 13 of the second pair of the post 3 are arranged coaxially at the bores 12 of one or the other of the two other pairs of holes of the offset arm 6 and the holes 9a of one or the other of the two pairs of holes 9a of the waiting room 9 for the passage of the second lower screw 10, depending on whether it is desired to fix the guardrail post 3 to its upright safety standing position of FIGS. 1 to 6 or to its tilted standing position represented in FIGS. 7 and 8. the variant of the piece 9 to 12, the end portions of each guard post 3 and each offset arm 6 comprise the same pairs of bores 12,13 arranged in the same manner as the pairs 12,13 holes described with reference to Figures 1 to 8 to allow the railing posts 3 to occupy a standing upright safety position shown in Figure 10 or an inclined safety standing position shown in Figure 12.

To fix the two end portions of the guard post 3 and the offset arm 6 in the stirrup holding part 9, the procedure is as follows. Firstly, the end portion of the offset arm 6 is disposed between the two parallel branches 3b of the lower end portion of the guard post 3 so as to coaxially dispose the bores 13 of the pair upper post 3 at the holes 12 of the upper pair of the offset arm 6 by considering Figure 9 or 11 to then introduce the upper screw 10 through the holes 12,13 and hold axially by the corresponding nut 11. Then the other lower screw 10 is introduced through the bores 13 of the lower pair of the guard post 3 and through the two bores 12 of one or the other of the two pairs of bores of the part of the end of the offset arm 6 according to whether it is desired to position the guardrail post 3 in its upright standing position or in its upright service standing position, the second screw 10 then being locked in translation by the Then, the end portions thus assembled of the railing post 3 and the offset arm 6 are introduced into the stirrup holding part 9 as shown in FIG. 10 or in FIG. It should be noted that the two side walls 9b of the stirrup holding part 9 which extend perpendicularly to the corresponding support plate 5 may have at their two upper parallel edges respectively two internal flanges 9c perpendicular to the walls 9b and which allow to prevent the lifting of the guard post 3 relative to the waiting part 9 and to the support plate 5 by the screw heads 10 and the nuts 11 bearing under the two flanges 9c, although in principle, such an uprising can not normally take place in view of the significant weight of the counterweight 7 preventing such uplift. Under these conditions, the introduction of the end portions assembled to each other 25 of the guard post 3 and the offset arm 6 in the stirrup holding part 9 will be carried out in a parallel direction to the side walls 9b of this piece. The counterweight 7 will also prevent any displacement of the assembled end portions of the post 3 and the offset arm 6 out of the stirrup of the waiting part 9 in a horizontal direction.

According to the variant embodiment shown in FIGS. 13 to 19, each guard post 3 at its lower end portion pivotally mounted relative to the end portion of the associated offset arm 6 and to the corresponding waiting part 9 to allow this post to tilt 3032987 12 from its standing safety position shown in particular in Figure 18 to a folded storage position above the offset arm 6 and the counterweight 7 as shown in Figure 19. Figure 13 shows that the lower end portion of the railing post 3, the end portion of the offset arm 6 and the block-shaped holding part 9 comprise the same pairs of holes 13, 12, 9a arranged in the same way as the pairs of holes 13,12,9a previously described. However, the end portion of the offset arm 6 which covers the block of the waiting part 9 and the lower end portion of the guard post 3 covering the inclined face at the end of the waiting part 9 and the end portion of the offset arm 6 by its three U-shaped walls 3a, 3b are fixed to the waiting part 9 by a single screw bolt 10 and nut 11 passing through the upper bores 13,12,9a end portions of the guardrail post 3 and the offset arm 6 and the holding part 9 to allow the guard post 3 to pivot about the bolt 10,11 between its two standing service positions and folded storage, especially above the offset arm 6. The guard post 3 is maintained in its standing upright safety position of Figure 18 by a stand 14 whose one end is pivotally attached to the one of the side walls 6b of the offset arm 6 and the opposite end ee is traversed by the intermediate rail 4 passing through the lateral branches 3b of the railing post 3 through two coaxial bores 3c respectively formed in the two side walls 25 3b of the post 3 approximately in the middle of the latter. The end of the stand 14 is pivotally mounted to the corresponding side wall 6b of the offset arm 6 by means of a screw bolt 15 passing through a bore 14a of the end of the stand 14 and two coaxial holes 6c through the two side walls 6b and a nut 13 axially locking the screw 15. The stand 14 comprises a first flat rectilinear portion 14b whose end comprises the bore 14a and a second flat end 14c flat portion located in the same plane that the first part 3032987 13 rectilinear 14b and shorter in length than the latter. The end portion 14c extends obliquely with respect to the first straight portion 14b and is traversed by the intermediate rail 4. The angle of inclination of the second end portion 14c relative to the first portion 14b is determined so as to ensure the blocking through the intermediate rail 4 of the body-pier post 3 to its standing safety position. The two parts 14b and 14c comprise a light 14d extending longitudinally to these two parts and allowing the intermediate rail 4 to slide along the light 14d during the folding of the guard post 3 of its standing upright position. safety at its folded position above the offset arm 6, or vice versa. Thus, to perform this folding, the user exerts a force on the guard post 3 in the opposite direction of the clockwise, as indicated by the arrow F1 in Figure 18 and simultaneously exerts a force 15 on the kickstand 14 in the counterclockwise direction as indicated by the arrow F2 in this figure to disengage the end portion 14c of the intermediate rail 4 and cause the sliding of the rail along the light 14d of the stand 14 to the folded position of the latter above the offset arm 6 and the counterweight as shown in Figure 19. As is apparent from Figures 1 to 19, each guard post 3 comprises not only the intermediate coaxial holes 3c of passage of the intermediate rail 4, but also two coaxial holes 3d formed in the vicinity of the upper end of the guard post 3 25 through its two side walls 3b to allow the passage of the top rail 4. It should be noted that the holes 3c and 3d may have different diameters depending on the diameter of the upper and lower rails 4 and, therefore, the foldable legs 20 may have length and width 3 0 different. One of the side walls 3b of the guard post 3 comprises, associated with each of the two holes 3c and 3d of this wall, a foldable flat tab 20 integral with this side wall in the same plane as the latter in 3032987 14 extending through the bore 3c, 3d in a direction substantially perpendicular to the core wall 3a of the railing post 3 and, preferably, the foldable lug 20 diametrically traverses the bore 3c, 3d of the side wall 3b.

Each foldable tab 20 is formed directly by cutting in the side wall 3b of the railing post 3. In addition, each foldable tab 20 has near its free end a bore 20a, better visible in Figures 2, 16 and 17 and allowing the passage of a fastener 21, such as a self-drilling screw 10 visible in Figures 4 and 18. Once the guard posts 3 fixed on their respective support plates 5 to their standing position, as explained previously in the various embodiments, the user exerts with the help of his finger or a tool a force on each of the foldable tabs 15 to move it around its connection to the corresponding edge of the drilling 3c, 3d in the space between the two side walls 3b of the guard post 3 to a position perpendicular to the corresponding side wall 3b. Then, the user can introduce the upper and intermediate stringers 4 through their respective holes 3c, 3d of 20 guard posts and once these smooth positioned permanently, the user blocks the smooth 4 relative to the guard posts -body 3 by screwing the self-drilling screws 21 through the holes 20a of the folded tabs 20 and the corresponding smooth 4, each tab 20 being supported along the corresponding portion of a smooth 4.

If necessary, the foldable tabs 20 of the various guard posts 3 could be brought to their folded position in these posts by one end of a rail 4 introduced successively into the holes 3c or 3d of these posts. Figures 20 and 21 show a vertical guard post 3 30 forming part of a fixed safety railing, in this case rigidly fixed to a parapet 8 bordering at least partly the outer periphery of the ground 2 of a roof terrace of a building.

Each railing post 3 of such a fixed guardrail is also made from a folded sheet having a U-shaped cross-section along the post as described with reference to FIGS. 1 to 19. .

In addition, the guard post 3 also comprises two pairs of coaxial bores 3c, 3d respectively intermediate and upper crossing the two side walls 3b of the post 3 and the two orifices 3c, 3d made in one of the side walls 3b. comprise respectively two folding tabs 20 identical to the foldable tabs 20 previously described and 10 being able to be folded manually or at one end of a rail so as to occupy a position perpendicular to the side wall 3b in the space defined between the two side walls 3b of the railing post 3 to allow the blocking of the corresponding rail 4 inserted through the holes 3c, 3d by a self-drilling screw through the end hole 20a 15 of each leg 20 and the smooth 4. It is therefore unnecessary to again describe in detail all the parts of these fixed railing posts common to those described with reference to Figures 1 to 19. According to FIGs 20 and 21, the parallel guard posts 3 are rigidly fixed, by means of support legs 38, to support plates 31 rigidly fixed to the horizontal face of the acroterium 8 with the various support plates. 31 each support plate 31 has a substantially Z-shaped 25, one of which 31a of the branches is fixed on the horizontal face of the acroterium 8 by fastening screws 31 are spaced apart from each other along the acroterium 8. , not shown, and the other horizontal leg 31b extends perpendicularly from the vertical face of the acroterium 8 above the ground 2. Each support leg 30, of rectangular cross section or, where appropriate, square, at its lower end fixed by welding on the horizontal branch 31b of the support plate 31 and extends vertically above the ground 2.

Each support leg 30 is housed between the two side walls 3b of the lower end portion of the corresponding guard post 3, which side walls 3b can pinch the support leg 30 therebetween. The two side walls 3b of the lower end portion of the guard post 3 are rigidly attached to the support leg 30 by at least one fastener, such as a screw bolt 32 and nut 33, and Preferably, two 32,33 bolts are used to provide such a rigid attachment. The two screws 32 of the fixing bolts pass respectively through two pairs of coaxial bores 34 formed through the two side walls 3b of the guard post 3 and two pairs of coaxial bores 35 passing through two parallel walls 30a of the support leg 30. In addition, the lower edge 3a1 of the wall 3a forming the connecting core of the two side walls 3b of the guard post 3 protrudes from the lower edges 3b1 of the two side walls 3b of this post and bears against the horizontal branch 31b. from the support plate 31 to its position of attachment to the support leg 30 to allow the two lower edges 3b1 of the side walls 3b to disengage from the weld of the support leg 30 to the horizontal branch 31b of the support plate 31. Alternatively, each support leg 30 could be attached to the bracket branch 31b of the support plate 31 in an inclined manner to allow the guard post 3 to be inclined as well. born as in some of the previously described embodiments. According to the embodiment variant shown in FIGS. 22 and 23, the guard posts 3 are also part of a fixed safety guard. According to such a safety railing, each of the guard posts 3 is rigidly fixed to a support plate 5 itself fixed to the ground by any appropriate means, such as unrepresented fastening screws. The various support plates 5 of the vertical guard posts 3 are regularly spaced along an acroterium 8 bordering at least part of the outer periphery of the ground 2 of a roof terrace of a building, which plates 5, of rectangular or square shape, 3032987 17 may be arranged in abutment by one of their sides on the vertical face of the acroterium 8. Each of the guard posts 3 of Figures 22 and 23 is identical to each of the guard posts 3 described with reference to FIGS. 20 to 21 and will therefore not be re-detailed. Each of the support plates 5 comprises a support leg 30 which may be identical to the support leg 30 described with reference to FIGS. 20 and 21 and which is fixed on the plate 5 by welding projecting perpendicularly from the center of this plate.

Each support leg 30 is housed between the two side walls 3b of the lower end portion of the guard post 3, which side walls 3b can clamp the two parallel side walls 30a of the support leg 30. The part the lower end of the guard post 3 is fixed to the support leg 30 by at least two fastening members 30b, 15 such as for example two self-drilling screws passing through two offset holes 36 of the two side walls 3b of the post 3 and the two parallel side walls 30a of the support leg 30 to ensure a rigid attachment of the lower end portion of the post 3 to the support foot 30. Thus, each guard post 3 is fixed rigidly to its support plate 20 5 to extend vertically to the ground 2 near the acroterium 8. FIGS. 24 and 25 show another alternative embodiment of rigid fixing of each of the guard posts 3 of a guard e-body fixed to a parapet 8 bordering at least in part the outer periphery of the floor 2 of a roof terrace of a building.

According to this variant embodiment, each of the guardrail posts 3 is fixed to the vertical face of the acroterium 8 by means of a support plate 40 in the form of a square whose one of the branches 41 is attached to the vertical face of the acroterium 8 by any appropriate means, such as for example unrepresented fastening screws, and the horizontal branch, perpendicular to the vertical face of the acroterium 8 vertically supports the railing post 3 above the ground 2. A support leg 30 which may be identical to each of the support legs 30 described with reference to FIGS. 20 to 23, is fastened, for example by welding, to the horizontal branch 42 of the plate. 40 of support 40 extending perpendicularly above the branch 42 itself located above the ground 2. The support leg 30 is housed between the two side walls 3b of the lower end portion of the post corresponding railing 3, the These side walls 3b can clamp the two parallel side walls 30a of the support leg 30. The lower end portion of the guard post 3 is rigidly fixed to the support leg 30 by two upper and lower screw fixation bolts 43. and nuts 44, the screws 43 passing through two pairs of coaxial bores 45 of the two side walls 3b of the lower end portion of the guard post 3 and two pairs of coaxial bores 35 passing through the two parallel side walls 30a of the foot 30, the nuts 44 for axially locking the two screws 43.

The above-described design of each of the guard posts, whether belonging to a self-locking safety railing or a fixed guardrail, significantly reduces manufacturing costs compared to the guard posts. - traditional bodies. In addition, with each guard post of open section, an inertia equivalent to that of a tube-shaped guard rail can be obtained for a large amount of similar material. Furthermore, the surface treatments of each railing post of the invention can be performed before the cutting and bending operations of each post, for example the galvanizing of the steel sheets constituting each railing post can 25 be performed before cutting. Finally, the presence of foldable tabs integrated in the sheet metal of each of the railing posts avoids the use of additional parts that were previously used to attach the rails forming handrail rail posts, significantly reducing costs also reduces the time of installation of the rails forming a handrail at the guard posts.
