Description
DOMAINE TECHNIQUE DE L’INVENTIONTECHNICAL FIELD OF THE INVENTION
La présente invention vise un dispositif d’accès sécurisé pour un matériel de soutènement. Elle s’applique, notamment, aux soutènements fixes ou amovibles positionnés dans le cadre de travaux de voiries, par exemple.The present invention relates to a secure access device for support equipment. It applies, in particular, to fixed or removable supports positioned as part of road works, for example.
ÉTAT DE LA TECHNIQUESTATE OF THE ART
Généralement, lors de travaux en sous-sol, une tranchée est pratiquée dans le sol. Les ouvriers travaillant sur des fondations ou des réseaux enterrés doivent descendre dans la tranchée pour y avoir accès. Actuellement, l’entrée ou la sortie dans la tranchée des ouvriers est effectuée au moyen d’une échelle posée contre la paroi de la tranchée qui est renforcée par un soutènement. Cependant, les risques de chute sont importants, notamment lors d’intempéries.Generally, when working underground, a trench is made in the ground. Workers working on foundations or buried utilities must descend into the trench to gain access. Currently, workers enter or exit the trench by means of a ladder placed against the wall of the trench which is reinforced by a support. However, the risk of falling is significant, especially during bad weather.
Il existe des plateformes munies d’échelles conçues spécifiquement pour certains soutènements ou échelles à crinoline. Cependant, ils ne sont pas adaptables aux différents soutènements existants ou équipés d’un mécanisme peu ergonomique et complexe à installer.There are platforms equipped with ladders designed specifically for certain supports or caged ladders. However, they are not adaptable to the various existing supports or equipped with a mechanism that is not very ergonomic and complex to install.
La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these drawbacks.
À cet effet, selon un premier aspect, la présente invention vise un dispositif d’accès sécurisé pour un matériel de soutènement comportant une plateforme franchissant le soutènement, dans lequel la plateforme comporte :
– de part et d’autre du soutènement, au moins un échelon,
– au moins un mors fixe de blocage de la plateforme au soutènement, le mors fixe étant lié à la plateforme et franchissant le soutènement et
– au moins un mors déplaçable de blocage de la plateforme au soutènement, le mors déplaçable étant en regard du mors fixe et
– un moyen de du mors déplaçable par rapport au mors fixe,
dans lequel les mors sont en tôle.To this end, according to a first aspect, the present invention relates to a secure access device for support equipment comprising a platform crossing the support, in which the platform comprises:
– on either side of the support, at least one rung,
– at least one fixed blocking jaw from the platform to the support, the fixed jaw being linked to the platform and crossing the support and
– at least one movable blocking jaw from the platform to the support, the movable jaw being opposite the fixed jaw and
– a means of moving the jaw in relation to the fixed jaw,
in which the jaws are made of sheet metal.
Grâce à ces dispositions, les mors sont aisément adaptables à tout type de soutènement. De plus, le coût de fabrication est très faible puisque la tôle est un matériau peu onéreux. Enfin, le dispositif est résistant, de conception basique, soit très simple à installer puisque les mors prennent appui sur le soutènement de part et d’autre du soutènement.Thanks to these provisions, the jaws are easily adaptable to any type of support. In addition, the manufacturing cost is very low since sheet metal is an inexpensive material. Finally, the device is resistant, of basic design, very simple to install since the jaws rest on the support on either side of the support.
Dans des modes de réalisation, au moins un mors est obtenu par découpe laser.In embodiments, at least one bit is obtained by laser cutting.
Le coût de fabrication des mors est encore réduit.The manufacturing cost of jaws is further reduced.
Dans des modes de réalisation, chaque mors comporte au moins deux orifices de fixation du mors déplaçable au mors fixe.In some embodiments, each jaw has at least two holes for fixing the movable jaw to the fixed jaw.
Grâce à ces dispositions, chaque orifice peut correspondre à une position de réglage des mors.Thanks to these arrangements, each orifice can correspond to a jaw adjustment position.
Dans des modes de réalisation, le dispositif objet de la présente invention comporte au moins un boulon inséré dans chaque orifice.In some embodiments, the device which is the subject of the present invention comprises at least one bolt inserted into each orifice.
La fixation d’un mors à l’autre est facilitée et ne demande pas d’outil particulier.Attaching one jaw to the other is easy and does not require any particular tool.
Dans des modes de réalisation, le dispositif comporte, de plus, au moins une échelle comportant au moins un échelon.In some embodiments, the device further comprises at least one ladder comprising at least one rung.
Grâce à ces dispositions, l’échelle est sécurisée à la plateforme.Thanks to these provisions, the ladder is secured to the platform.
Dans des modes de réalisation, au moins une échelle comporte une crinoline.In embodiments, at least one ladder includes a crinoline.
La crinoline empêche un utilisateur de tomber, lorsqu’une hauteur importante est à franchir.The crinoline prevents a user from falling, when a significant height is to be crossed.
Dans des modes de réalisation, le dispositif objet de la présente invention comporte, de plus, au moins un appui d’une échelle au soutènement.In some embodiments, the device that is the subject of the present invention further comprises at least one support from a ladder to the support.
Grâce à ces dispositions, la sécurisation de l’échelle est accrue.Thanks to these provisions, the safety of the ladder is increased.
Dans des modes de réalisation, le dispositif objet de la présente invention comporte au moins deux ensembles comportant un mors fixe, un mors de blocage et un moyen de positionnement.In some embodiments, the device that is the subject of the present invention comprises at least two assemblies comprising a fixed jaw, a locking jaw and a positioning means.
Grâce à ces dispositions, la plateforme comporte plusieurs appuis contre le soutènement rendant l’ensemble plus stable.Thanks to these provisions, the platform has several supports against the support making the whole more stable.
Dans des modes de réalisation, la plateforme comporte au moins deux garde-corps latéraux et un portillon à rappel automatique.In embodiments, the platform comprises at least two side railings and a gate with automatic return.
Grâce à ces dispositions, on évite à un utilisateur positionné sur la plateforme d’en tomber.Thanks to these provisions, a user positioned on the platform is prevented from falling.
