Definitions
- the invention relates to a device for secure access to a confined space, in particular a confined space with lateral access, and an enclosure equipped with such an access device.
- a confined space can be defined as a totally or partially closed volume (building, structure, equipment, installation ...) that has not been designed and built to be occupied permanently by people, nor intended to be but which may occasionally be temporarily occupied for maintenance, maintenance, cleaning, occasional and more or less frequent operations, or unscheduled operations following exceptional events.
- the atmosphere within a confined space may also present risks to the health and safety of persons entering it because of the design or location of the structure, a lack of natural ventilation, materials, substances or fluids contained therein or used therein, equipment that is used in them, or the nature of the work performed in them.
- US 5,431,248 discloses an access device of this type comprising two or four telescopic support arms.
- US 5,617,963 discloses an access device attached to the flange of a side opening by clamping jaws.
- exhaust devices may be used on the ground or on a platform.
- the DBI-SALA® device thus proposes a device having a support fixed without tools on the rim of the lateral opening on which is fixed an articulated rotary arm whose one end can be positioned inside the confined space to support a man.
- the pivoting arm inserted inside the confined space extends away from the walls: it is then difficult to introduce tools or other via the manhole.
- the installation time is relatively long and this device can not support more than one person at a time and its weight remains high, greater than 50kg, making it difficult to transport.
- the aim of the invention is to overcome these disadvantages by proposing a device for secure access to a confined space, comprising:
- the first arm comprises at least one anchoring element located at a predetermined distance from the mast
- the second arm is provided with at least two pulleys whose axis of rotation is perpendicular to the plane defined by the mast and the first and second arms, a pulley being located at one end of the second arm attached to the mast and another pulley being located at a predetermined distance from the mast, the anchoring element and said at least two pulleys being arranged to allow the passage of a rope from the anchoring element to the pulleys without interfering with the mast and the first and second arm,
- the mast has at least one fastener for cooperating with an opening of the confined space.
- the proposed access device can thus be fixed to a manhole, more precisely to an external rim of the manhole, via the fastener or members: a fastener can thus be easily and quickly performed in a few minutes only.
- the device according to the invention is also relatively compact so that it can be easily transported. It also has few parts, so it is relatively light and easy to make. Finally, the different parts being fixed rigidly to each other (without possible movement relative to each other), the device according to the invention has the advantage of being robust and to support two men.
- the fastener or fasteners may in particular be shaped to be fixed on elements of the opening for closing it.
- a manhole has on its periphery a rim pierced with orifices for attaching a closure plate.
- the fastener or fasteners are advantageously shaped to be fixed on this flange, preferably via the orifices of the latter, for example via removable screw-nut type fasteners or pins.
- the fastener or fasteners may extend to the side of the second arm, particularly in the immediate vicinity thereof.
- the fastener or members may be arranged to position the second arm bearing against an inner surface of the opening when they cooperate with it.
- the mast may comprise at least two fasteners, in particular fixed rigidly to the mast, extending in a plane perpendicular to the plane defined by the mast and the first and second arms, on either side of the mast. This can improve the maintenance of the access device.
- a clamp may be shaped to be clamped on an outer edge of a manhole, for example via removable fasteners of the screw-nut type or pins.
- said at least one fastener may define an axis port parallel to the second arm.
- This orifice can have an elongate or oblong shape, extending for example in the direction of the mast, or an elongated and curved shape, the curvature is directed towards the end of the mast secured to the second arm. These shapes make it easier to match with another existing hole around the manhole.
- the mast may be formed of two parts whose ends are nested and secured by removable fastening elements. It is thus possible to dismantle the access device in order to transport it, or even to fix first to the manhole the part comprising the fasteners, then to secure the other part of the access device to the part already fixed and possibly to the manhole.
- a first nested end may define a U-shaped housing whose concavity is open in a direction opposite to the second arm and a second nested end may be received inside the housing, resting against internal surfaces of the housing. housing.
- the second nested end may then comprise a pierced fixing lug cooperating with an orifice formed in a bottom wall of the U-shaped housing of the first end, a removable fastening element assembling the fixing lug to the bottom wall of the housing.
- This fastener may be in the form of a screw-nut assembly, for a robust attachment.
- the bracket may be part of the aforementioned fasteners. It can then participate in fixing the access device to the manhole via the fastener.
- the removable fasteners used to secure the two nested portions of the mast may be selected from a pin through the corresponding openings of the nested ends and a screw-nut assembly.
- the fasteners may extend in perpendicular directions for better attachment.
- two parallel pins may be provided, one arranged at above the other and extending perpendicular to the plane defined by the mast and the arms.
- the screw-nut assembly can then extend parallel to the first and second arms.
- the second arm may be an H-section section.
- the first arm and the mast may furthermore be hollow closed profiles.
- the second arm may comprise at least one anchor element located at a predetermined distance from the mast, which may be used to secure safety elements (rope ladder, fall arrest device) or tools.
- This anchor element can support one of the aforementioned pulleys.
- the access device according to the invention is intended to facilitate access to an enclosure defining a confined space, via a manhole present on a side wall of the enclosure.
- this type of enclosure is cylindrical, with a vertical axis of symmetry in use, although it may extend horizontally.
- the access device is intended to be arranged so that the support mast extends vertically and the two arms horizontally, the second arm extending inside the confined space through the opening , especially along an inner surface of this opening.
- the invention thus also relates to an enclosure comprising a side wall provided with a manhole having on its periphery an outer rim remote from the side wall, defining for example a surface, particularly flat, pierced with orifices, characterized in that it is provided with an access device according to the invention secured to said manhole, in which:
- the access device mast extends vertically or substantially vertically above the manhole, the first arm extending perpendicularly or substantially perpendicularly to the side wall of the enclosure and the second arm extending to the inside the manhole, resting against an upper internal surface of said manhole,
- At least one fastener of the access device is in abutment against the outer rim and secured to the latter by removable fastening elements.
- the attachment can thus be performed in a simple manner.
- the access device is pressed against the inner wall of the manhole so that it reduces very little access to the inside of the manhole: men and equipment can enter and exit while the access device is attached.
- the invention finally relates to a method of installing an access device according to the invention, to a manhole formed through a side wall of an enclosure, said manhole having on its periphery an outer rim remote from the side wall, defining for example a surface, particularly flat, pierced with orifices.
- the installation process comprises the following steps:
- the mast extending vertically or substantially vertically above the manhole
- the first arm extending perpendicularly or substantially perpendicular to the side wall of the enclosure and the second arm extending inside the manhole, resting against an upper internal surface of said manhole
- FIG. 1 shows an exploded perspective view of a secure access device to a manhole according to one embodiment of the invention
- FIG. 2 represents a perspective view of the same access device, in the assembled state
- FIG. 3 shows the same access device attached to an outer edge of manhole, the latter being partially shown;
- the terms upper, lower refer to the up and down directions, in the position of use of the access device in which the mast is substantially vertical, ie substantially in the direction of gravity.
- substantially horizontal, longitudinal or vertical means a direction / plane forming an angle of not more than ⁇ 20 °, or not more than 10 ° or not more than 5 ° with a direction / a horizontal, longitudinal or vertical.
- substantially parallel or perpendicular means a direction / a plane deviating from not more than ⁇ 20 °, or even more than 10 ° or not more than 5 ° of a direction / parallel or perpendicular plane .
- Figures 1 and 2 show a secure stop device 10 comprising:
- a first arm 14 fixed rigidly to an end 12a of the mast 12, here an upper end, and extending perpendicularly to the mast 12,
- a second arm 16 rigidly attached to another end 12b of the mast 12 and extending perpendicularly to the mast 12, in the same plane as the plane defined by the first arm 14 and the mast 12, but in a direction opposite to the first arm 14.
- the first arm 14 comprises an anchoring element, rigidly fixed, located at a predetermined distance from the mast 12. This distance may in particular be chosen as a function of the length of the first arm 14 and the mast 12.
- a single anchoring element 18 is provided at the free end 14a of the first arm 14. It is in the form of a tab pierced with an orifice 19 for fastening a fastening element, for example the type carabiner, or for the passage of a rope.

- the anchoring element 18 and the pulleys 20 and 22 are arranged to allow the passage of a rope from the anchoring element 18 to the pulleys 20, 22 without interfering with the mast 12 and the first and second arm 14, 16.
- a pulley 20 can be located in the extension of the second arm 16, at the end of the mast 12, the other pulley 22 can be disposed below the second arm 16, at the end thereof.
- This pulley 22 can be fixed to the second arm 16 by means of a fixing lug 23.
- the invention is not limited to a particular arrangement of the pulleys and the anchoring element, nor to a particular number of these elements.
- the positioning of the pulleys and the anchoring element could be different, in particular the pulleys could occupy more distant positions with respect to the mast and the second arm and the anchoring element could be at a distance from the mast, but not at the end of the first arm 14.
- Other anchoring elements and / or pulleys could also be provided, as needed.
- the pulley 22 may also be disposed at a predetermined distance from the mast 12, for example at a distance sufficient to be inside the enclosure and sufficiently far from the inner walls of the enclosure to avoid friction between the rope and these walls. It will be noted that the length of the second arm is then sufficient so that its free end can be disposed inside different types of enclosure and to allow positioning of the pulley 22 as specified above.
- the length of the first arm will be chosen according to the length of the mast so as to allow a connection of a rope to the anchoring element and the pulleys, without interference with the access device 10.

- the fasteners 24, 26 are here similar to fastening rings. Note that they are located in the immediate vicinity of the second arm 16 in the example shown.
- the mast 12 has a fixing orifice 28 located between the fasteners 24, 26 and whose axis is parallel to the second arm 16. It will be noted that this orifice 28 is here of oblong shape whose length extends substantially parallel to the axis of the mast 12. This orifice 28 also forms a fastener within the meaning of the invention.

- these fixing elements are two pins 30, 32, or axes, which extend parallel to each other and perpendicular to the plane defined by the mast 12 and the first and second arms 14, 16.
- these pins are arranged one above the other and pass through holes provided for this purpose in the first and second parts 121, 122 fitted to the mast, these orifices being matched for the passage of the pins 30, 32.
- These pins may be connected by a chain or the like to the mast 12 to avoid losing them.
- a screw-nut assembly comprising a screw 34 makes it possible to associate the first and second parts 121, 122 via the orifices 28, 126 described above, in a direction parallel to the longitudinal direction of the second arm 16.
- the second arm 16 comprises two anchoring elements, 36, 38, located at a distance from the mast 12, here at the pulley 22, namely at the free end of the second arm 16. They are secured the tab 23 supporting the pulley 22.
- the various anchoring points, 18, 36, 38 are preferably made in such a way as to comply with the safety standards in force for people, such as class B of the EN795: 2012 standard.
- the second arm 16 is in the form of a profile with a cross-section in H.
- FIGS. 4-7 show the access device 10 described above fixed on a manhole 84 of an enclosure (not shown in Figure 3). The same access device 10 is shown schematically in different configurations of use in FIGS. 4-7.
- FIG 3 shows in particular an outer rim 40 of the manhole 84 which usually extends away from the side wall 82 of an enclosure 80 (see Figures 4-7).
- This outer rim 40 defines a bearing surface 42 pierced with orifices 44. It will be noted that these orifices 44 are distributed over the entire periphery of the outer rim 40, here of annular shape. These orifices 44 are initially intended to ensure the closure of the manhole 84 by a plate screwed by screws passing through these orifices 44. In order to ensure good closure of the manhole, the bearing surface 42 is therefore generally flat and extends all around the manhole 84.
- the mast 12 of the access device 10 When attached to the manhole 84, the mast 12 of the access device 10 extends vertically (or substantially vertically) above the manhole.
- the first arm 14 extends substantially perpendicular to the side wall 82 of the enclosure, while the second arm 16 extends inside the manhole, substantially parallel to the axis thereof.
- This second arm 16 bears against an upper internal surface 46 of the outer rim 40.
- the fasteners 24, 26 bear against the bearing surface 42 of the outer rim.
- the securing of the access device 10 is obtained by two fixing screws 48, 50 by means of tightening nuts (not shown), these screws being inserted through the orifices 25, 27 of the fastening members and orifices 44 of the outer rim 40 matched.
- the lower part of the access device 10, namely the second arm 16 and the portion 121 of the mast 12, is first fixed to the manhole 84.
