Description

The present invention relates to a device for attaching a plinth to a railing, to an assembly of a skirting board on a railing using such a fastening device, and to a method of mounting such an assembly. .

It relates more particularly to an assembly for a structure, especially a structure at height, comprising: a guardrail provided with several amounts spaced apart from each other, each upright being mounted on a shoe for anchoring said amount on said structure ; and at least one plinth fixed on an outer face of at least one upright or shoe of the railing by means of a fixing device. On a guardrail, it is customary to fix a plinth or a succession of skirting boards, at ground level of the structure, between the uprights and the hooves, to form a retaining wall flush with the ground. Skirting boards are used to prevent persons or objects from slipping under the guardrail, and for example objects fall on workstations or taxiways below the structure, and in danger of people. The skirting boards are generally fixed to the railing when the structure does not have a parapet or wall and therefore its edge falls directly into the void, or when the parapet or wall has a height lower than a given safety height . To fix a skirting P on an upright M or a shoe S of a railing GC, it is known, with reference to FIG. 1, to use a stirrup E which encases the upright M or the shoe S, and then to screw the two ends of the stirrup E onto a clamping plate PS by means of two screws V, this clamping plate PS being previously engaged in a slideway G provided for this purpose on the inner face of the plinth P. Such However, assembly is relatively complicated, both during the assembly phase and during the disassembly phase. Indeed, this assembly requires to place the clamping plate PS in the slideway G of the baseboard P, then to center the clamping plate PS relative to the stirrup E to align the screws V with the threaded holes provided in the plate PS tightening. In addition, this assembly requires the provision of a slide G on the inner face of the baseboard P to accommodate the clamping plates PS, making it more complex and increasing the manufacturing costs of the baseboard P.

The present invention aims to solve these problems by providing a device for attaching a skirting board on a railing that allows easy and fast assembly / disassembly of the plinth, while ensuring reduced production costs for the final assembly and for the plinth in particular.

For this purpose, it proposes a device for attaching a plinth to a railing, of the type comprising: a support member of the baseboard having a groove for receiving a falling edge of the skirting board; and - clamping means of the support member on the railing, said clamping means being arranged on the support member and shaped to move the support member between a loosened position in which the receiving groove is spaced apart from the guardrail by a predetermined distance to allow insertion of the falling edge of the plinth, and a tight position in which the receiving groove is brought closer to the railing to press the falling edge of the plinth against said guardrail. body. Thus, with such a fastening device according to the invention, the plinth has an edge falling on its inner face which engages in the receiving groove of the support member, and then the clamping means are tightened to press this falling edge against the railing, in this case against an external face of the post or the guardrail shoe. It is therefore easy to mount the skirting board on the railing, because no prior centering is necessary, and furthermore such a fastening device does not require a slide on the plinth, but only requires a falling edge to be supported by the support member.

According to a first embodiment, the support member has a generally "U" shape and comprises two wings interconnected by a base, the two wings each having a free end in which is formed a notch defining the receiving groove. In this first embodiment, the support member is mounted to overlap on the post or shoe rail, that is to say the support member sits around the post or shoe guard, in the same way that the caliper of the state of the art, and it receives the plinth in its receiving groove before tightening. In this case, the base of the fixing device comes opposite an inner face of the upright or hoof, opposite to the outer face, and the notches of the wings protrude from the outer face of the upright or hoof to receive the falling edge of the plinth before tightening the clamping means. According to a second embodiment, the support member has a general shape in "C" and comprises two bent branches interconnected by a central portion, said central portion having at each of the junctions with the bent limbs a notch defining the receiving groove . In this second embodiment, the support member is slidably mounted on a male element projecting from the outer face of the upright or the guardrail shoe; the support member having a shape substantially complementary to the male member. The curved shape of the branches prevents the support member from falling off the male element, the only way to remove the fixing device of the male element is to slide it. Once mounted on the male element, the support member receives the plinth in its receiving groove before tightening. According to one feature, the clamping means comprise at least one clamping screw engaged in a threaded through hole formed on the support member, the clamping screw or screws being shaped to bear against the guardrail to move the support member between its loosened position and its tight position. Thus, the one or more clamping screws bear against the jamb or guardrail to move the support member between its loosened position and its tight position. In other words, the tightening screw (s) move or push the support member towards the inside of the structure on which the railing is mounted, until the baseplate is sufficiently pressed against the post or shoe and prevent its release. . In the case of the first embodiment, the support member has a threaded through hole formed on the base of the support member, and the clamping means comprise a clamping screw engaged in this threaded orifice. In this way, the clamping screw bears against the inner face of the post or guardrail shoe, opposite the outer face, to move the support member. In the case of the second embodiment, the support member has two threaded through holes formed respectively on the free ends of the curved branches, and the clamping means comprise two clamping screws respectively engaged in said threaded holes. In this way, the clamping screws bear against the male member of the post or guard shoe to move the support member. According to a possibility of the invention, the support member is made in one piece. Advantageously, the support member has at least one overhanging protrusion above the receiving groove to prevent the falling edge of the plinth from emerging from the receiving groove once the support member is in a tight position. Indeed, this projection prevents the skirting out of the throat out of reception. The invention further relates to an assembly for a structure, in particular an overhead structure, comprising: - a railing provided with several amounts spaced from each other, each upright being mounted on a shoe mooring said amount on said work ; and at least one plinth fixed on an outer face of at least one upright or shoe of the railing by means of a fixing device; the assembly being remarkable in that the fastening device is according to any one of the preceding claims, wherein: - the support member receives a falling edge of the plinth in its receiving groove; and the clamping means cooperate with the post or shoe to move the support member between a loosened position in which the receiving groove is spaced from the outer face of the post or shoe a predetermined distance to allow insertion. the falling edge of the plinth, and a tight position in which the receiving groove is brought closer to the outer face of the upright or shoe to press the falling edge of the plinth against said outer face of the upright or shoe. During tightening, the clamping means thus come to rest on the railing, in this case on the post or shoe rail, to push the support member towards the inside of the structure (in a direction which brings the plinth closer to the guardrail) and thus bring the plinth abutting against the railing and clamping it in a tight position.

In the case of the first embodiment described above, the support member is mounted to overlap on the upright or shoe with the base disposed opposite an inner face of the upright or shoe, opposite to the outer face, and with the notches of the wings protruding from the outer face of the upright or shoe to receive the falling edge of the plinth before tightening the clamping means. In the case of the second embodiment described above, the post or shoe has a male element projecting from its outer face and the support member has a shape complementary to the male element and is slidably mounted on said male element. , the two bent branches being shaped to hold the support member in place on the male element. In a particular embodiment, the falling edge of the plinth has at least one inner lug protruding in a direction opposite to the amount or shoe.

This or these internal lugs may advantageously be associated with the projection of the overhanging support member above the receiving groove, to ultimately prevent the plinth from being able to exit towards the top of this receiving groove. The invention also relates to a method of mounting an assembly according to the invention, comprising the following steps: - mounting of the support member on the post or shoe with the clamping means loosened for the organ bracket is in a loose position; - insertion of the falling edge of the plinth into the receiving groove; - Clamping the clamping means to move the support member to its tight position and press the falling edge of the plinth against the outer face of the amount or shoe.

The present description relates to two embodiments of a fastening device 1, 2 of a baseboard 3 on a railing 4, and therefore on two associated assemblies of a baseboard 3 on a guard rail 4. The first Embodiment is described with reference to Figures 2 to 6, and the second embodiment is described with reference to Figures 7 to 11.

In both embodiments, the railing 4 comprises several posts 40 spaced from each other in a longitudinal direction X, each upright 40 being mounted on a shoe 41 of mooring the upright 40 on a structure, such as a roof or terrace. The shoe 41 is shaped to moor or fix the amount 40 on the structure, for example by ballasting, screwing, gluing, welding, etc. Of course, the invention is not limited to the mode of attachment or docking of the shoe 41 on the structure. Although not illustrated, the railing 4 also comprises rails or bars which connect the uprights 40 between them, and which extend in the longitudinal direction X, with classically but not exclusively a high rail and at least a low rail or intermediate.

The amount 40 and the shoe 41 each have an outer face, oriented on the outside of the work, and on which is fixed the baseboard 3 which covers the outer face. The amount 40 and the shoe 41 also each have an inner face, opposite to the outer face and oriented on the inside of the structure.

In both embodiments, the baseboard 3 comprises a substantially vertical main wall 30, provided with an internal face oriented on the inside of the structure and which faces the outer faces of the upright 40 and the hoof 41 of the guard The baseboard 3 is formed in the form of a profile extending in the longitudinal direction X at the ground level of the structure, preferably at a predetermined height above the ground to allow water flow. The plinth 3 has, projecting from its inner face, a falling edge 31 which extends substantially vertically, in other words substantially parallel to the main wall 30. This falling edge 31 extends to a predetermined distance from the main wall 30. In the first embodiment, and as illustrated in Figures 2, 4, 5 and 6, the falling edge 31 protrudes from the upper longitudinal free edge of the main wall 30. E Furthermore, the falling edge 31 of the plinth 3 has an internal lug 32 projecting from its external face facing the inner face of the main wall, towards the outside of the structure, that is to say say in a direction opposite to the upright 40 or the shoe 41 once the skirting 3 in place on the railing 4. In the second embodiment, and as shown in Figures 7, 10b and 11b, the falling edge 31 protrudes in the central part of the main wall 30, away from the upper and lower longitudinal free edges of the main wall 30.

The following description relates to the two attachment modes of the baseboard 3 on the railing 4, and more particularly on the rear face of the upright 40 or the shoe 41, with a detailed description of the two fastening devices 1, 2 and associated fixing steps of the baseboard 3 on the railing 4. In the first embodiment, and as illustrated in FIGS. 2 to 6, the first attachment device 1 comprises a support member 10 of the baseboard 3. This support member 10 consists of a single piece, that is to say, made in one piece, having a general shape "U". The support member 10 has a median plane of symmetry and has two wings 11 substantially parallel and symmetrical with respect to the median plane, these two wings 11 being interconnected by a base 12. The two wings 11 each have a flat wall, substantially vertical in situation on the railing 4, which ends with a thicker free end in which is provided a notch 13. The two notches 13 together define a substantially vertical and longitudinal receiving groove for receiving the falling edge 31 of the baseboard. The two wings 11 each have a protrusion 14, substantially horizontal, overhanging above the corresponding notch 13, thus forming a retaining hook of the falling edge 31 of the plinth 31 once the latter inserted into the notches 13. In furthermore, the first fixing device 1 comprises a clamping screw 15 engaged in a threaded through orifice formed in the base 12 of the support member 10; this threaded orifice and this clamping screw 15 extending in a transverse direction Y substantially perpendicular to the longitudinal direction X and the vertical direction Z. For the first embodiment, the attachment of the baseboard 3 on the railing 4 is as follows.

In a first step, the clamping screw 15 is partly unscrewed and its free end does not protrude from the base 12 of the support member 10. Next, this support member 10 is mounted to overlap on the upright 40, just above the shoe 41. Indeed, the support member 10 in "U" is dimensioned and shaped to substantially match the amount 40, the mounting clearance. It would of course have been conceivable for the support member 10 to be mounted overlapping on the shoe 41, instead of the post 40. During this step of placing the support member 10, this support member 10 is brought from the inside of the structure, with the base 12 which faces the inner face of the upright 40, or even abuts against this inner face of the upright 40, and with the free ends of the wings 11 which protrude from the external face of the upright 40. The wings 11 are sufficiently longer than the width of the upright 40 so that the notches 13 of the wings 11 protrude from the outer face of the upright 40 to receive the falling edge 31 of the plinth 3. In a second step , just inserting the falling edge 31 of the baseboard 3 inside the notches 13 forming receiving groove. In this loose position of the support member 10, the notches 13 are sufficiently spaced from the outer face of the upright 40 so that the falling edge 31 of the plinth 3 is mounted in the receiving groove 13 with a mounting clearance J between said falling edge 31 and said outer face of the upright 40, as illustrated in FIG. 5. In a third and final step, the clamping screw 15 is screwed against the internal face of the upright 40 and which, as and as the tightening / tightening, moves the support member 10 in the transverse direction Y towards the inside of the structure, which leads the receiving groove to approach the outer face of the upright 40. Thus, the falling edge 31 of the baseboard 3 approaches the outer face of the upright 40 until the mounting clearance J is zero, that is to say until said falling edge 31 is pressed and pressed against the outer face of the upright 40, as illustrated in FIG. In the closed position reached, the projections 14 of the support member 10 and the pin 32 of the falling edge 31 of the skirting board 3 together prevent this falling edge 31 from coming out of the receiving groove 13 by sliding upwards. In the second embodiment, and as illustrated in FIGS. 7 to 11, the second fixing device 2 comprises a support member 20 of the plinth 3. This support member 20 consists of a one-piece part, which is ie made in one piece, having a general shape in "C".

The support member 10 has a median plane of symmetry and comprises two curved branches 21 symmetrical with respect to the median plane and bent inwardly of the "C", these two curved branches 21 being interconnected by a central portion 22.

The central portion 22 has, at each of the junctions with the bent branches 21, a notch 23. The two notches 23 together define a substantially vertical and longitudinal receiving groove for receiving the falling edge 31 of the plinth. In addition, the second fixing device 2 comprises two clamping screws 25 engaged threaded orifices 24 through formed on the free ends of the curved branches 21 of the support member 20. These threaded orifices 24 open substantially in front of the central portion 22, are symmetrical with respect to the median plane and are slightly inclined with respect to the transverse direction Y and point towards the interior of the "C".

In the context of this second embodiment, the shoe 41 has a male element 42 projecting from its external face and the support member 20 has a shape substantially complementary to this male element 42 so as to be slidably mounted on said male element 42. The curved shapes of the two branches 21 keeps the support member 2 in place on this male element 42. For the second embodiment, the attachment of the skirting board 3 on the railing 4 is as follows. In a first step, the clamping screws 25 are partially unscrewed and their free ends do not protrude from the branches 21 of the support member 20. Next, this support member 20 is slidably mounted on the male element 42 of the It should of course have been possible for the male element 42 to be provided on the upright 40, instead of the hoof 41. During this step of placing the support member 20, this support member 20 is sliding downwardly on the male element 42, with the central portion 22 which faces said male element 42 at a predetermined distance D, while the branches 21 bear against the male element 42, as shown in FIG. Figure 10a. This distance D allows the notches 23 of the support member 20 to protrude from the male element 42 to receive the falling edge 31 of the plinth 3.

In a second step, the falling edge 31 of the plinth 3 is inserted just inside the notches 23 forming a receiving groove. In this loose position of the support member 20, the notches 23 are sufficiently spaced from the male element 42 so that the falling edge 31 of the plinth 3 is mounted in the receiving groove 23 with a mounting clearance J between said falling edge 31 and said male member 42, as illustrated in Figure 10b. In a third and final time, the two clamping screws 25 which bear against the male element 42 are screwed on and which, as soon as the screwing / clamping is in motion, displaces the support member 20 in the transverse direction Y towards the inside of the structure, which causes the receiving groove 23 to approach the male element 42 and thus the distance D to decrease, as illustrated in FIG. 11 a. Thus, the falling edge 31 of the plinth 3 approaches the male element 42 until the mounting clearance J is zero, that is to say until said falling edge 31 is plated and tight against the male member 42, as illustrated in Figure 11b. Of course the implementation example mentioned above is not limiting and further improvements and details can be made to the fixing device according to the invention without departing from the scope of the invention where other clamping means of the support member may for example be made instead of the clamping screws.
