Description

Guardrail system for securing an edge of a construction and method of securing implementing such a guardrail system

The invention relates to a guardrail system for securing an edge of a construction and to a securing method using such a guardrail system.

In particular, the invention relates to a railing system of the type comprising:

- at least one post extending along a post axis between a base intended to be secured in the vicinity of the edge of the construction and a vertex opposite the base, the post having an external surface,

- at least one cross member extending along a cross member axis, and

- at least one blocker, in which the blocker comprises:

- a fixing part having a fixing axis and configured to be mounted on the post with the fixing axis parallel to the post axis,

a holding part arranged to extend over the external surface of the post when the fixing part is mounted on the post, the holding part having an open housing along a housing axis transverse to the fixing axis, the housing being adapted to receive a part of the cross so that the cross axis extends transversely relative to the post axis when the fixing part is mounted on the post.

Document FR 2 979 931 describes a railing system of this type which is entirely satisfactory.

The invention aims to improve the modularity of the known railing system.

To this end, according to a first aspect, the invention provides a railing system of the aforementioned type in which the fixing part is configured to be able to slide on the post along the post axis when said fixing part is mounted on the post, and in which the post has at least one stop arranged at a determined height relative to the base of the post to stop the blocker.

Thus, the blocker can slide freely on the post and be placed at a desired height depending on the height of the stop. The modularity of the railing system is improved. It is thus possible to adapt the railing system to the edge of the construction to be secured, whether it is the horizontal or inclined edge of a slab, a hopper, a staircase or the like.

The post can have a symmetry of revolution around the post axis, and the fixing part can be configured to be able to pivot along the post axis when said fixing part is mounted on the post. These provisions further improve the modularity of the railing system by being able to change the orientation of the blocker.

The fixing part can be fitted with play on the outside surface of the post, the fixing axis being coaxial with the post axis.

The outer surface of the post can be cylindrical with a circular section, and the fixing part can comprise at least one fastening member adapted to extend circumferentially over at least one essential part of the external surface of the post.

The stopper can extend transversely to the post axis on the outside surface of the post.

The stopper can extend tangentially over the outer surface of the post.

The stop can be configured to support a part of the crosspiece.

Said at least one stop may include an upper stop arranged at a height of between 0.90 m and 1.30 m, preferably 1.10 m.

Said at least one stop may comprise a lower stop arranged at a height of between 0.40 m and 0.70 m, preferably 0.55 m.

The holding part can include:

a body comprising a support member extending transversely with respect to the fixing axis, the support member having a mounting opening along a guide axis parallel to the fixing axis, the mounting opening being delimited by a blocking surface oriented towards the fixing part and intended to be placed facing the external surface of the post when the fixing part is mounted on the post, and

- a corner being configured to be reversibly inserted into the mounting opening of the support member, in contact with the blocking surface, and to wedge the cross-member part received in the housing formed between the post, the member support and the corner when the fixing part is mounted on the post and said corner is inserted in the mounting opening.

The body of the holding part and the fixing part can be made in one piece by a bent rod.

According to a second aspect, the invention proposes a method for securing an edge of a construction implementing a railing system as defined above, the method of securing providing for the steps consisting in:

- secure the base of the post in the vicinity of the edge of the construction,

- mount the fixing part of the blocker on the post by sliding the fixing part on the post with the fixing axis parallel to the post axis until the stop stops the blocker, the holding part of the blocker extending over the outer surface of the post,

- place a part of the crosspiece in the housing of the blocking holding part so that the crosspiece axis of the crosspiece extends transversely to the post axis.

When the post has a symmetry of revolution around the post axis, and the fixing part is configured to be able to pivot along the post axis when said fixing part is mounted on the post, the securing method may provide , during the step of mounting the fixing part on the post, orient the holding part by pivoting the fixing part on the post.

When the stopper is configured to support a part of the crossmember, the securing process can provide, prior to the step of mounting the blocker on the post, the step of placing a crossmember on the stopper.

When said at least one stop comprises an upper stop arranged at a height of between 0.90 m and 1.30 m, preferably 1.10 m, the securing method may provide for mounting the fixing part of an upper blocker on the post and placing an upper cross member in the housing of the upper blocker holding part so that the upper cross member extends to a height between 0.90 m and 1.30 m, preferably 1.10 m.

When said at least one stop comprises a lower stop arranged at a height of between 0.40 m and 0.70 m, preferably 0.55 m, the securing method can provide for mounting the fixing part of a lower blocker on the post and placing a lower cross member in the housing of the holding part of the lower blocker so that the lower cross member extends to a height of between 0.40 m and 0.70 m, preferably 0.55 m.

In particular, the security process can successively provide for:

- place the lower stop on the post,

- mount the fixing part of the lower blocker on the post until the lower stop stops the lower blocker,

- place the upper stop on the post,

- mount the fixing part of the upper blocker on the post until the upper stop stops the upper blocker.

In the figures, the same references designate identical or analogous elements.

The figures represent a railing system 1 for securing an edge of a construction and in particular the horizontal or inclined edge of a slab, a hopper, a staircase or the like.

The railing system 1 according to the invention comprises one or more posts 5 intended to extend vertically in the vicinity of the edge of the slab, one or more sleepers 15 and one or more blockers 20 each adapted to mount at least the one of the crosspieces 15 on one of the posts 5 so that the crosspiece 15 extends transversely, that is to say in a secant manner and not necessarily perpendicular, to the post 5.

In FIG. 1, only part of a particular embodiment of the railing system 1 is shown, it being understood that the description which is made of it can be transposed to the rest of the railing system 1 or to any guard system - body produced in accordance with the invention.

The railing system 1 comprises lower crosspieces 15 mounted on the post 5 by means of a lower blocker 20, and upper crosspieces 15 mounted on the post 5 by means of a upper blocker 20.

In Figure 2, the post 5 extends along a post axis A between a base 5a configured to be secured, for example fitted into a hole, near the edge of the construction and a top 5b opposite the base 5a. The post 5, for example metallic, is tubular and has an outer surface 6 having a symmetry of revolution around the post axis A and, in particular, cylindrical with a circular section.

The post 5 comprises one or more stops 7 arranged and configured each to support one of the blockers 20 and, in the embodiment shown, part of one of the crosspieces 15. In particular, in the embodiment shown, the post 5 has an upper stop 7 for supporting the upper blocker 20 and one of the upper cross members 15 and a lower stop 7 for supporting the lower blocker 20 and one of the lower cross members 15.

Each stopper 7 extends transversely with respect to the post axis A on the outer surface 6 of the post 5. In particular, each stopper 7, for example produced by a metal rod welded to the outer surface 6 of the post 5, s 'extends tangentially on the external surface 6 of the post 5 so as to present:

a stop surface 8 on the outer surface 6 of the post 5, oriented towards the top 5b of the post 5 and on which the blocker 20 can rest, directly or indirectly, that is to say by means of a cross 15,

a support surface 9 extending from the external surface 6 of the post 5, oriented towards the top 5b of the post 5 and on which a part of one of the crosspieces 15 can rest.

The support surface 9 may have a concavity oriented towards the top 5b of the post 5.

Each stopper 7 is arranged at a height determined relative to the base 5a of the post 5 in order to be able to position the crosspieces 15 at the desired heights. For example, the lower stop 7 arranged at a height H1 between 0.40 m and 0.70 m, preferably 0.55 m, and the upper stop 7 is arranged at a height H2 between 0.90 m and 1, 30 m, preferably 1.10 m.

The post 5 can also comprise a square 10 mounted, for example fitted, in the vicinity of the base 5a and comprising one or more lugs 11 extending parallel to the post axis A, at a distance from the external surface 6 of the post 5 to fix a plinth.

Each cross member 15, for example metallic, is tubular along a cross member axis B and has an outer surface 16 having a symmetry of revolution around the cross member axis B and, in particular, cylindrical with a circular section.

In FIGS. 3 and 4, the blocker 20 comprises:

a fixing part 21 having a fixing axis C and configured to allow the blocker 20 to be mounted on the post 5 with the fixing axis C parallel to the post axis A,

a holding part 25 receiving a part of the cross member 15.

In the embodiment shown, the holding part 25 comprises a body 26 made in one piece by a rod, for example metallic, bent.

The body 26 comprises a support member 27 extending transversely relative to the fixing axis C. In particular, the support member 27 consists of two lateral strands 28 parallel to each other and having two ends connected by a transverse strand 29. The support member 27 has a concavity obtained, in the particular embodiment shown, by bending the side strands 27. The side strands 27 and the transverse strand 29 define a mounting opening 30 along an axis of guide D parallel to the fixing axis C, the mounting opening 30 having a blocking surface 31 oriented towards the fixing part 21.

The body 26 also includes a guide member 37 extending transversely with respect to the fixing axis C, opposite the concavity of the support member 37. In a similar manner to the support member 27, the guide 37 consists of two side strands 38 parallel to each other and having two ends connected by a transverse strand 39. The guide member 37 is plane with the side strands 38 superimposed respectively on the side strands 28 of the support member 27 and the transverse strand 39 superimposed on the transverse strand 29 of the support member 27. Two lateral strands 28, 38 superimposed respectively of the support member 27 and of the guide member 28 are connected one to the on the other hand a vertical strand 45. The lateral strands 38 and the transverse strand 39 of the guide member 37 delimit another mounting opening 40 along the guide axis D, the mounting opening 40 having a locking surface 4 1 oriented towards the fixing part 21.

The holding part 25 also includes a corner 50 extending along a corner axis E between first 50a and second 50b opposite ends. The corner 50 has opposite contact surfaces 51 extending along the corner axis E by converging towards one another from the second end 50b to the first end 50a. The corner 50 is thus configured to be reversibly inserted, by its first end 50a, into the mounting opening 40 of the guide member 37 and the mounting opening 30 of the support member 27 of the body 26 with one of the contact surfaces 51 in contact with the locking surfaces 31, 41 of the transverse strands 29, 39 of the support member 27 and of the guide member 37.

On its second end 50b, the corner has a return 52 extending substantially perpendicular to the contact surfaces 51.

An oblong notch 53 is formed through the contact surfaces 51 to allow the passage of a pin 60 ensuring guidance of the movement of the wedge 50 relative to the body 26. In particular, the pin 60, produced in the form of a rod, for example metallic, folded comprises a loop 61 extending along a loop axis on the side of one of the contact surfaces 51 and two tabs 62 extending in opposite directions parallel to the loop axis on the side from the other contact surface 51. The pin 60 is shaped so that the tabs 62 rest on the lateral strands 38 of the guide member 37 of the body 26 when the loop 61 is wound around the transverse strand 39 of the member guide 37 of the body 26. The wedge 50 can thus be moved relative to the body 26 while being guided by the pin 60 sliding in the notch 53.

The support member 27, the guide member 37 and the wedge 50 define a housing L open along a housing axis F transverse to the guide axis D and to the fixing axis C. The housing L is adapted to receive a part of at least one cross member so that the cross member axis B extends transversely with respect to the post axis A.

In the embodiment shown, the fixing part 21 is made in one piece with the folded rod forming the body 26 of the holding part 25.

In particular, the fixing part 21 includes two hooking members 22 constituted by curved strands 23 around the fixing axis C, each curved strand 23 extending one of the free lateral strands of the guide member and the support member. The curved strands 23 are superimposed and extend respectively in two parallel planes comprising, one, the guide member and, the other, part of the support member. The curved strands 23 have a curvature adapted to extend circumferentially with play on at least one essential part, that is to say at least 50%, preferably at least 75%, of the external surface 6 of the post 5.

In connection with FIGS. 5 to 8, a method for securing an edge of a construction implementing the railing system 1 is described.

One of the lower crosspieces 15 is placed on the support surface 9 of the lower stopper 7 so as to extend at a height of between 0.40 m and 0.70 m, preferably 0.55 m.

The fixing part 21 of the lower blocker 20 is fitted with play on the external surface 6 of the post 5 and can slide with the fixing axis C coaxial with the post axis A until the lower stop 7 stops the lower blocker 20 via the lower cross member 15. Alternatively, the lower stop 7 could directly stop the lower blocker 20. The holding part 25 of the lower blocker 20 extends over the external surface 6 of the post 5 and can be oriented in a desired first orientation 01 by pivoting the fixing part 21 on the post 5.

The upper stop 7 can then be placed, for example welded, on the post 5 at the desired height H2.

One of the upper crosspieces 15 is placed on the support surface 9 of the upper stopper 7 so as to extend at a height of between 0.90 m and 1.30 m, preferably 1.10 m.

The fixing part 21 of the upper blocker 20 is fitted with clearance on the external surface 6 of the post 5 and can slide with the fixing axis C coaxial with the post axis A until the upper stop 7 stops the upper blocker 20 via the upper cross member 15. Alternatively, the upper stop 7 could directly stop the upper blocker 20. The holding part 25 of the upper blocker 20 extends over the external surface 6 of the post 5 and can be oriented in a desired second orientation 02, for example offset angularly with respect to the first orientation 01, by pivoting the fixing part 21 on post 5.

Another lower cross member 15 can be placed on the support member 27 of the retaining part 25 of the lower blocker 20 so that the lower cross member 15 extends to a height of between 0.40 m and 0.70 m from preferably 0.55 m, in a direction other than the previous lower cross member 15. The corner 50 is inserted by its first end 50a into the mounting opening 40 of the guide member 37 and the mounting opening 30 of the support member 27 with one of the contact surfaces 51 in contact with the blocking surfaces 31, 41 facing the external surface 6 of the post 5 to wedge the cross-member part 15 received in the housing L formed between the post 5, the support member 27 and the corner 50.

In the same way, another upper cross member 15 can be placed on the support member 27 of the holding part of the upper blocker 20 so that the upper cross member 15 extends to a height of between 0.90 m and 1 , 30 m, preferably 1.10 m, in a direction other than the previous upper cross member 15. The corner 50 is inserted by its first end 50a into the mounting opening 40 of the guide member 37 and the mounting opening 30 of the support member 27 with one of the contact surfaces 51 in contact with the blocking surfaces 31, 41 facing the external surface 6 of the post 5 to wedge the cross-member part 15 received in the housing L formed between the post 5, the support member 27 and the corner 50.
