The present invention relates generally to the protection of persons working on building roofs. Regulations require the protection of people working on building roofs. It is known from the state of the art a modular construction, usually called module, which includes a living space and a roof overlying said living space, and fall protection equipment coupled to the roof. Generally said living space, of parallelepipedal general shape, is delimited by two vertical end faces interconnected by two vertical side faces. The fall protection equipment includes, on the one hand, two opposing guardrails, called end guard rails, each of which extends close to and along the upper edge of an end face and on the other hand, two other opposing railings, called side railings, which extend from one end railing to the other, near and along the upper edge of a side face . Said railings are able to take a raised position in which they delimit a closed perimeter protecting the operator against falls. In order to access or descend from the roof of the module without risk of falling, one or each of the side railings comprises a gate mounted movably between a closed position and an open position towards the inside of the perimeter defined by the equipment. fall protection device, which allows the operator to enter or leave the safety perimeter defined by the safety equipment. When two modules, each equipped with safety equipment, are juxtaposed in long-side, that is to say by their lateral faces, the side rails of the juxtaposed modules which extend facing one of the other let appear between them a passage whose ends open into the void.

3031998 2 The operator can move from the roof of one module to the other by opening the doors of the side railings facing to access the desired module. The operator who must perform sealing at a free end of the junction zone between the modules can then be tempted to open the corresponding gate of the module on which it is located, to take said passage and access said free end of the junction zone which must be sealed. But the operator is then likely to fall modules since no guardrail retains at the end of this area. The present invention aims to propose a new railing to reduce the risk of a fall operator at a free end of the passage defined between railings of two juxtaposed modules. To this end, the subject of the invention is a roof railing of a construction, preferably of modular construction, comprising a main body comprising at least one upper cross member and an upright, and an additional body, called a door, characterized in that that said gate is movably mounted along the upright of the main body between a first position, said low position, and a second position, said high position, said gate being also pivotally mounted relative to the main body, at least in one direction, called external direction, to be able to pass from a closed position in which it extends substantially parallel and in the extension of the main body to an open position in which it extends transversely, preferably perpendicularly, to the main body, said guard; body also comprising: - locking means configured for, in the low and closed position of the gate, to prevent pivoting of the gate lon in said outer direction, and for, in the high and closed position of said gate, allow said pivoting in the outer direction, and - a return spring arranged to exert on the gate a force in the direction of a return of the gate in the closed position .

Advantageously, the return spring is arranged with the locking means so that, when the gate is brought to the upper position and then pivoted in the outer direction, the gate is held in the open position by friction of the locking means against the upper rail. of the main body. According to an advantageous characteristic of the invention, said gate comprising an upper cross member, said locking means comprise an abutment element, fixed to the gate which, in the closed position of the gate, protrudes from the outside of the upper cross member. the gate opposite the upper rail of said main body. The outer side is defined by reference to the outer pivoting direction. According to an advantageous characteristic of the invention, the locking means also comprise an abutment portion, preferably formed by an edge of a recess provided in the abutment element, said recess edge being parallel to the amount of the door, said abutment portion being configured to limit the swing angle of the gate in the outward direction, so that the gate abuts against the upper rail of the main body of the side rail when said gate extends, by pivoting in the outside direction, substantially perpendicular to the main body of the side railing. According to an advantageous characteristic of the invention, said gate being also pivotally mounted with respect to the main body, in a sense, called internal direction, opposite said external direction, to be able to pass from said closed position in which it extends substantially parallel and in the extension of said railing, and a so-called inner open position according to which it extends transversely, preferably perpendicularly, to said guardrail, According to an advantageous characteristic of the invention, said gate comprising an amount, said amount of the main body is a tube inside which extends said amount of the gate. Preferably, said gate comprising an upright and an upper cross member, the upper end of said door jamb protrudes from the upright of the main body, so as to maintain the upper cross member of the door separated from the upper free edge of the main body upright . According to an advantageous characteristic of the invention, the return spring comprises a lower end connected to the upright of said main body and an opposite upper end connected to the door. The invention also relates to a construction, preferably modular, called module, comprising: - a living space and a roof overlying said living space, and - an anti-fall protection equipment coupled to the roof, characterized in that said Fall protection equipment includes one, preferably more than one, guardrail as described above. According to an advantageous characteristic of the invention, said module having two opposite lateral faces interconnected by two opposite end faces, said safety equipment comprises along and near the upper edge of one, preferably each face lateral, two railings, called side railings, the main bodies of said side railings being separated from each other by their gates, and said side rails extending, in the closed position of the gates, substantially parallel and in the extension of one another.

The invention also relates to a set of two modules as described above, characterized in that said modules are juxtaposed by two of their lateral faces, called juxtaposition faces, and in that said lateral guardrail, called juxtaposition railings, associated with a juxtaposition face of a module extend opposite the side or side railings associated with the juxtaposition face of the other module, defining between them a passage. According to a particular aspect, said assembly comprising an end face formed by two end faces of the modules and an end face formed by the other two end faces of the modules, the gate of the juxtaposition railing of each module is in open position. The invention also relates to a structure of four modules comprising first and second sets of modules as described above, characterized in that, each assembly comprising an end face formed by two end faces of the modules and a another end face formed by the other two end faces of the modules, the second set of modules is juxtaposed by one of its end faces against an end face of said first set of modules, and in that the gate juxtaposition guardrail, each module, located closest to an end face of the structure is in the open position to obstruct access, through said passage, to the end faces of the structure. The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which: FIG. 1 is a partial view of side railings equipping two modules according to the invention, each guard lateral body comprising a gate in the closed position; - Figure 2 is a view at another angle of a portion of Figure 1 showing one of the gates in the open position to the other module; FIG. 3 is a view from another angle of the side rails of FIG. 1 in the open position of each gate of one railing of a module towards the other module; FIG. 4 is a view at another angle of a portion of FIG. 1 showing two opposite side railing gates, each in open position towards the other module, so as to block access to one side of the passage defined between the opposite side railings of the two modules, while leaving access to the other side of the passage, to be able to access two additional modules juxtaposed to said modules by their gables; FIG. 5 is a view showing the passage existing between the opposite side railings of two juxtaposed modules according to the invention, on the side of one end of all of said modules, as well as the end of the juxtaposition zone. sealing between said modules; - Figure 6 is a view showing a railing gate according to the invention, in the open position towards the inside of the roof of said module. Referring to the figures and as recalled above, the invention relates to a guardrail of a safety equipment for the work of an operator roof module. Each module includes a living space and a roof overlying said living space, and fall protection equipment coupled to the roof. The living space, of parallelepipedal general shape, has two opposite end faces, interconnected by two opposite side faces. Said faces can be opened or closed by panels. In the example illustrated in the figures, the safety equipment comprises several guardrails to define a security perimeter on the roof of a module, in the erect state of its railings. Thus, in the example illustrated in the figures, each module is provided with safety equipment which comprises end guard rails 6 which extend in proximity to and parallel to the upper edge of the corresponding end faces of the housing. module, and 1 side railings which extend in proximity and parallel to the upper edge of the corresponding lateral faces of the module. Said lateral faces of the module are also called long faces and the end faces may also be designated by the term "pinion". For the sake of clarity, the railings are shown in the figures but not the walls and roofs of the modules. But, the juxtaposition zone 71 between two modules, one end 73 of which must be sealed by an operator, has been shown schematically in FIG. 5. This juxtaposition zone is covered by a covering element 72. Each side railing 1 comprises a main body 2 and an additional body, called gate 3. Said main body 2 comprises a lower cross member 21 and an upper cross member 23 interconnected at one end of said cross members by a post 22 and at their other end by another amount. Said gate 3 comprises an upright 32 and an opposite upright 34, an upper rail 33 and a lower rail 31. Said gate 3 is mounted movable parallel to the upright 22 of the main body 2 between a first position, said low position, and a second position said high position. Said gate 3 is also pivotally mounted relative to the main body 2, in a sense, called outside direction. Said external direction corresponds to a direction of pivot towards the outside of the module or to the outside of the perimeter delimited by the anti-fall device of the module. When the gate 3 is brought to the upper position by the operator, said gate 3 can then be pivoted by the operator, to pass from a closed position in which the upper rail 33 of the gate 3 extends substantially parallel and in the extension of the upper cross member 23 of the main body 2 of said railing, to an open position in which the upper cross member 33 of the gate 3 extends perpendicularly to the upper rail 23 of said main body 2 of the guardrail. The railing comprises locking means 4 configured for, in the low and closed position of the gate, prevent the pivoting of the gate 3 in said outer direction, and for the upper and closed position of said gate, allow said pivoting in the outside direction. The external pivoting mobility of each door allows the operator to easily move from one module to another juxtaposed module, and to simultaneously close at least one side of the passage between the two modules, while preventing an involuntary opening of one or more gates by the operator through the locking means which remain deactivatable by lifting the gate. Closing the passage between two modules by the gates dissuades the operator to take this passage and proceed to the sealing of one end of the juxtaposition zone of the modules while remaining in the security perimeter delimited by the bodyguard. When the gate 3 is in the low and closed position, the lifting of the gate makes it possible to deactivate said blocking means 4 so that the operator can thus pivot the gate 3 in the outer direction, to bring it substantially at right angles with the main body 2 of the railing so as to obstruct access to one end of the passage 7 between two modules juxtaposed in long pan. As detailed below, the locking means 4 comprise a locking element 40 fixed on the gate 3. The locking element 40 comprises an element 41, fixed to the gate 3, which, in the closed position of the gate 3, s' extends outwardly and from the outside of the upper rail 33 of the gate against the upper rail 23 of said main body 2.

In the example illustrated in the figures, the blocking element 40 is in the form of a flat iron substantially bent at a right angle so as to have an attachment portion 42 (oriented horizontally) applied against the top of the upper cross member 23 and an abutment portion, forming said element 41 (vertically oriented) applied against the lateral part, outer side, of said cross member 23 of the main body 2, in the closed position of the door 3. Thus, in the closed position of the gate 3, the abutment portion 41 which is applied facing the outer side of the crosspiece 23 of the main body 2 prevents the outward pivoting of the door 3 until it is raised to escape the abutment portion 41 in relation to the outer side of the cross member 23. In the example illustrated in the figures, a recess 43 is formed, for example by cutting, in the abutment portion 41. More specifically, this recess ent is formed in the lower corner of the abutment portion 41 furthest from the cross member 34 of the gate. This recess has a vertical edge, that is to say, parallel to the uprights, which limits the pivoting of the gate to the outside, to the open position, substantially perpendicular to the crossbar 23. In this open position, the abutment portion 41 abuts the vertical edge of the notch 43 against the outer side of the crossbar 23. This recess also has a horizontal edge, that is to say parallel to the sleepers. In the high and open position of said gate 3, said flat iron supports by the horizontal edge of the recess 43 formed in the abutment portion 41 against the top of the upper rail 23 of the main body 2. The railing comprises a spring of recall 5 arranged to exert on the gate 3 a force in the direction of a return of the gate 3 in the low and closed position.

In other words, the return spring 5 is arranged to pull the gate downwards and in the inner pivoting direction, opposite to the direction of external pivoting, until said gate 3 occupies said low and closed position. The return spring 5 comprises a lower end connected, by a support member 51, to the upright 22 of said main body 2 and an opposite upper end connected to the door 3. In particular the upper end of the spring 5 is connected to a support piece 52 fixed to the abutment portion 41 of the locking member 40 carried by the upper rail 33 of the door 3. The return spring 5 is a coil spring. In the closed position of the gate, the upper end and the lower end of the return spring 5 extend one on one side of the mean plane passing through said gate 3 and the main body 2, and the other of the other side of said mean plane. The lower end is located on the inside of the fall arrest equipment while the upper end is on the outside of the fall arrest equipment. Thus when the operator wishes to move the gate 3 from its open position to its closed position, it is sufficient for the operator to begin to rotate the gate in the inner direction. The return spring 5 accompanies the pivoting movement of the gate 3 to its closed position and also remembers the gate in the low position so that the locking means 4 are brought into the active position. The restoring force of the spring 5 allows the positioning of the abutment portion 41 against the outer side of the upper cross member 23 of the main body 2 of the corresponding side railing. In the high and open position, the gate 3 is held in said open position by friction of the locking means 4 against the upper cross member 23 of the main body 2. Furthermore, as recalled above, the locking means 4 also include an abutment portion formed by the edge of the recess 43 parallel to the post 32. This recess edge limits the swing angle of the door outwards so that the door 3 comes into outer abutment against the main body 2 of the railing 1 side, when said gate 3 extends substantially perpendicularly to the main body 2 of the railing 1 side. The return spring 5 reinforces the friction between the main body 2 and the locking element 40 fixed on the door 3, pulling the door 3 and thus the locking element 40 downwards, which generates a support of the blocking element against the upper cross member 23 of the main body. According to a preferred embodiment illustrated in the figures, the upright 22 of the main body 2 is a tube inside which extends in part the upright 32 of the door 3. In particular, the upper end of the upright 32 of the door 3 protrudes from the upright 22 of the main body so as to maintain the upper cross member 33 of the gate spaced from the upper free edge of the upright 22 of the main body 2. Such spacing facilitates the movement of the door. The tube which forms the upright 22 of the main body 2 is provided with a stop element (not shown) which extends inside the tube to limit the insertion length of the upright 32 of the door into the tube 22. Advantageously, said abutment element is formed by a screw which also makes it possible to fix to the tube 22 the support piece 51 of the lower end of the return spring. Said safety equipment comprises along and near the upper edge of each side face of a module, two guardrails 1, called side railings, as described above. The main bodies 2 of said side rails 1 are separated from each other by their gates 3. Said side rails 1 extend, in the closed position of the gates, substantially parallel and in the extension one of the other.

According to a particular embodiment using two modules, said modules are juxtaposed by two of their lateral faces, called juxtaposition faces. The one or more side rails 1, called juxtaposition guardrails, associated with a juxtaposition face of a module, extend facing one or more side rails 1 associated with the juxtaposition face of the other module, defining between them a passage 7 which opens into the vacuum at its ends. To make it possible to pass from one module to another and to simultaneously close the accesses on each side of the passage, the operator positions each railing in the up and open position towards the other module, that is to say to the outside, as shown in Figure 3. According to another embodiment using a structure of four modules, said structure comprises a first set of two modules and a second set of two modules as described above. The set of two modules has a first end face defined by two end faces of the juxtaposed modules and has a second end face defined by the other two end faces of the modules. Said second set of modules is juxtaposed by an end face of said second set against the second end face of said first set. The gate 3 of the guardrail 1 juxtaposition of each module located closest to an end face of the structure is brought to the upper and open position to obstruct access to the end faces of the structure through said passage 7. Thus, the gate 3 of the guardrail 1 juxtaposition of each module located closest to the first end face is in the open position to obstruct access to said first end face by said passage 7, while by allowing access to the other modules by the central portion of the passage left free between the open gates. Likewise, the gate of the juxtaposition guardrail of each module located closest to the second end face is in the open position to obstruct access to said second end face by said passage. As shown in FIG. 6, said gate 3 is also pivotally mounted with respect to the main body 2, in a direction, called inside direction, opposite to said external direction, between a closed position in which it extends substantially parallel and in the extension of said guardrail 2 (the upper cross member 33 of the door 3 then extending in the extension of the crosspiece 23 of said guardrail 2) and an inner open position in which it extends transversely, preferably perpendicularly, to said guard -body 1. The upper cross member 33 of the gate 3 then extends perpendicularly to the upper cross 23 of said railing 2, within the security space defined by the other guardrails. The spring 5 recalls the gate in the closed position. The swing mobility of the door on the inside allows the operator to access the roof securely. Indeed, the operator who climbs on the roof with a ladder hook can easily push the door to the inside of the roof to access said roof. The guardrails of said safety equipment are able to take an active configuration in which they are erected and an inactive configuration in which they are folded against the roof. Said safety equipment may be equipped with means for returning the fall protection equipment from its inactive position to its active position, and inactivation control means configured to control the passage of the anti-fall protection equipment. falling from its active position to its inactive position, as described in the patent application filed on June 27, 2014 by the Applicant under number FR1456018 and not yet published.
