Definitions
- the present invention relates to a protection device in the form of a barrier placed on a structure in order to prevent the fall of people moving over this structure.
- This protective device comprises, when assembled, at least two supports or vertical uprights interconnected by at least one rail and each fixed to the structure by means of a fixing element.
- Document 095/34719 describes an example that allows the fixing on a rail of posts themselves connected to each other by stringers. It should be noted that fixing is particularly complex and requires the placement of a large number of different parts. In addition, since disassembly is relatively difficult, this kind of barrier cannot be considered as a railing. 2
- Patent application EP-A-0059154 describes a retractable platform railing, comprising several support uprights which are articulated at one of their ends. These amounts are arranged in a fitted stop and are immobilized in the normal position by a key secured to the articulated face.
- the present invention aims first of all to propose a device which makes it possible to increase the safety of people moving and working on works or worksites, more particularly located at height, which does not have the drawbacks of the 'state of the art.
- the present invention therefore aims to provide a simple device which comprises a limited number of parts which, when assembled together, make it possible to produce a "self-locking" protection system, that is to say which makes it possible to avoid inadvertent or unexpected disassembly or separation of the parts constituting the protection device.
- the present invention also aims to propose a system which is of the provisional type, that is to say which allows easy and rapid disassembly of the various components.
- the present invention relates first of all to a self-locking protection device of the railing type disposed on a structure, possibly temporarily, comprising at least two supports or uprights which will be placed along an axis essentially perpendicular to the plane of the structure to be fitted with protections, the uprights each being fixed using 4
- the device further comprises at least one heald which secures it between the two supports or uprights, the protective device being characterized in that the fixing element has an opening which is produced so that one end of the support or amount can enter it in a first direction and can not leave this opening and / or detach from the fastening element after rotation about an axis parallel to the axis substantially perpendicular to the plane of the structure towards a second direction.
- the heddle is held integral with said support or upright using fixing means preventing rotation of said supports or uprights after joining. This makes it possible to prevent the end of the support or upright from leaving the opening of the fixing element.
- fixing means are constituted by upper cleats which have a geometry such that the heddle can only be detached from the supports or uprights after lifting and rotation.
- said support or upright has at one of its ends a nozzle capable of penetrating into the opening of the fixing element, this nozzle having in section preferably perpendicular to the first direction at least one dimension smaller than that obtained in section preferably perpendicular to the second direction.
- the device may optionally include a plinth, which can also be placed between at least two supports or uprights dice to be fixed by means of the fixing element on the structure to be fitted with protections. 5
- the present invention also relates to each of the constituent elements of the device of the invention as mentioned above.
- the present invention finally relates to a method of mounting a protection device as described above, characterized in that one fixes, preferably permanently, at least two fixing elements on a structure to be protected, in that that we have
- FIG. 1 represents an overall perspective view of the protection device according to the present invention as already mounted and placed on the structure to be fitted with protections.
- Figures 2 show a view of the fastening element before and after its placement on the structure to be protected.
- Figures 3 show a sectional view of the fastening element in the mounting position and in the locking position. 6
- Figures 4 to 6 each time represent a perspective view according to the different stages of the mounting method according to the present invention allowing the placement respectively of a support or amount, a heald and a plinth as shown in the figure 1.
- FIG. 1 shows an overview of the fixing device according to the present invention.
- This fixing device 1 comprises first of all at least two fixing elements 4 also called “bells" because of their particular shape which is open on their underside which will be placed directly in contact with the structure 2 to be protected.
- the device further comprises at least two supports or uprights 3 which will be placed vertically and between which will be fixed horizontally at least one heald 5 and possibly a plinth 9 ensuring the joining of said supports or uprights.
- the device comprises two supports or uprights 3 which are placed along an axis ⁇ essentially perpendicular to the plane ⁇ of the structure 2 to be protected.
- Plan ⁇ of structure 2 means the plane of the essential surface of structure 2.
- the plane ⁇ of a structure will be determined in relation to the edge of a building, the edge of the steps a staircase, the upper and lower borders of an inclined plane, etc.
- the placement of the various components of the protection device is carried out as follows: firstly, provision is made for the attachment of at least two fastening elements 4 directly to the structure 2 to be fitted with 7
- protections which can be a rail, a platform, a staircase, or any other support having a surface, essentially horizontal (relative to the vertical axis of a plumb line).
- guardrail-type protection for an inclined structure, staircase or inclined plane type. In this case, account will be taken of the essentially horizontal surface formed by the upper and lower bearings of said inclined planes on which the above-mentioned fixing elements 4 will be fixed.
- the fastening elements 4 are permanently attached to the structure 2 by means known per se, which can simply be a weld in the case of metallic elements, or the attachment using rivets, screws, bolts and nuts.
- these various fixing elements 4 will be placed just on the edge of the structure 2, so as to allow easier introduction of the uprights or supports 3.
- this fastening element 4 which is shown in more detail in FIGS. 2 and 3, has an opening 6 which has an asymmetrical shape. More particularly, the opening 6 in the fastening element has in section preferably perpendicular to a first direction VI at least one dimension smaller than that obtained in section preferably perpendicular to a second direction V2, the first direction VI being called commonly the direction of introduction of the support or upright, while the second direction V2 is commonly called the locking direction. 8
- This feature will allow a self-locking support or upright 3 placed "vertically” in the fixing element 4 and to prevent its extraction from the latter.
- This self-locking (or self-locking) of the system allows it to be disassembled only by scrupulously following the sequence of disassembly operations contrary to that of assembly. By simply assembling the arm, the installation of the protection device is completed by locking the assembly.
- the end 13 of said support or upright 3 In order to self-locking the support or upright 3 to the fixing element 4, provision is made for the end 13 of said support or upright 3 to have a nozzle capable of penetrating into the opening 6 of the fixing element 4 and having in section perpendicular to the first direction VI at least one dimension smaller than that obtained in section perpendicular to the second direction V2. This excludes the fact that the support or upright 3 placed vertically, when it is placed in the second direction V2, does not come out of the fixing element 4 (FIG. 4c).
- the supports or uprights 3 placed vertically are cantilevered relative to the structure 2 to be protected, so as to further facilitate the placement of these in the corresponding fastening elements 4 and therefore the introduction of the end 13 9
- the device will only be fully self-locking if the rotation of the different supports or uprights 3 placed vertically is prevented. This is achieved by placing at least one heald 5 between at least two consecutive supports or uprights 3.
- the upper side of the heald 5 is placed on the cleats 15 by tilting the latter at a certain angle in order to allow the edge of the heald 5 to be introduced into said cleats 15 (FIG. 5b).
- said smooth 5 is folded towards the supports or uprights 3 and it is allowed to move vertically downwards quite simply by gravity (FIG. 5c). In this way, the rotation of said supports or uprights will be prevented.
- To disassemble the boom it is necessary to lift and rotate around a horizontal axis to release it from its support. This sequence prevents inadvertent disassembly. It is only after this series of operations that rotation along a vertical axis is possible.
- the procedure for placing said heald 5 is essentially similar to that of inserting the upper edge of said plinth 9 into cleats 16 provided for this purpose on each of the supports or uprights 3 placed vertically (FIG. 6a).
