Abstract
Description
La présente invention a trait à un outil permettant l'ouverture et le basculement des tampons ou plaques d'égouts dans une position stable. The present invention relates to a tool allowing the opening and tilting of tampons or manhole covers in a stable position.
La position stable d'un tampon est définie lorsque celui-ci est maintenu basculé dans son cadre sans risque de retomber.The stable position of a tampon is defined when it is kept tilted in its frame without risk of falling.
On connaît des outils de ce genre qui permettent uniquement l'ouverture des tampons. Dans la majorité des cas, l'utilisateur emploie plus facilement soit la pioche de terrassier, soit la barre à mine, soit le marteau d'égouttier, soit le pied de biche, soit une pièce de masse, voire même un tournevis ou un crochet pour ouvrir les plaques ou tampons d'égouts. Tools of this kind are known which only allow the opening of tampons. In the majority of cases, the user more easily uses either the earthmoving pick, the crowbar, or the drip hammer, or the crowbar, or a ground piece, or even a screwdriver or a hook to open the sewer plates or plugs.
Lorsque le tampon est ouvert à l'aide de cet outil, l'utilisateur introduit un deuxième outil, tel qu'un crochet de manutention, pour permettre le basculement de la plaque ou du tampon d'égout dans sa position stable. When the buffer is opened using this tool, the user introduces a second tool, such as a handling hook, to allow the tilting of the sewer plate or buffer in its stable position.
Ces outils ne s'adaptent pas à tous les tampons, étant donné que ces derniers comportent des encoches de faibles dimensions ou des pattes latérales comportant des systèmes de sécurité. Ainsi, l'utilisateur doit avoir en sa possession un outil par tampon pour les ouvrir. These tools are not suitable for all buffers, since these have small notches or side tabs with safety systems. Thus, the user must have in his possession a tool per pad to open them.
De plus, les outils décrits précédemment ne permettent donc pas de placer le tampon d'égout dans sa position stable, ce qui risque d'entrainer des accidents, étant donné que l'utilisateur doit le maintenir soit avec les mains, soit avec un deuxième outil, mais mal adapté, avant de le faire basculer dans sa position stable. In addition, the tools described above therefore do not allow the sewer pad to be placed in its stable position, which risks causing accidents, since the user must hold it either with the hands or with a second tool, but unsuitable, before tilting it in its stable position.
C'est à ces inconvénients qu'entend plus particulièrement remédier la présente invention. It is these drawbacks that the present invention intends to remedy more particularly.
L'outil a pour but d'aider l'opérateur à placer la plaque ou le tampon d'égout dans sa position stable à l'intérieur de son cadre sans risque de retomber. The purpose of the tool is to help the operator place the manhole cover or pad in its stable position inside its frame without the risk of falling.
A cet effet, l'outil comprend une tige cylindrique dont l'une des extrémité est prolongée par un talon à profil rectangulaire pourvu d'une pointe recourbée, tandis que perpendiculairement à l'axe principal de l'outil est fixée une butée cylindrique. La butée cylindrique est soudée sur le talon rectangulaire à proximité de la pointe recourbée. To this end, the tool comprises a cylindrical rod, one end of which is extended by a heel with a rectangular profile provided with a curved point, while a cylindrical stop is fixed perpendicular to the main axis of the tool. The cylindrical stopper is welded to the rectangular heel near the bent point.
En outre, le talon à profil rectangulaire est prévu d'un poids supérieur à celui de la tige cylindrique pour constituer une masse de frappe plus importante. In addition, the rectangular profile heel is provided with a weight greater than that of the cylindrical rod to constitute a greater striking mass.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective éclatée illustrant l'outil suivant La présente invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is an exploded perspective view illustrating the tool according to the present invention.
Fig. 2 à 5 sont des vues schématiques montrant l'utilisation de l'outil pour l'ouverture des tampons d'égouts. Fig. 2 to 5 are schematic views showing the use of the tool for opening the sewer pads.
On a représenté en fig. 1 un outil 1 permettant L'ouverture et le basculement des plaques ou tampons d'égouts 2 pour les placer dans une position stable à l'intérieur de leur cadre 2a. There is shown in fig. 1 a tool 1 allowing the opening and tilting of the sewer plates or buffers 2 to place them in a stable position inside their frame 2a.
L'outil 1 est constitué d'une tige cylindrique la dont l'une des extrémités est prolongée par un talon lb à profil rectangulaire. The tool 1 consists of a cylindrical rod la, one of the ends of which is extended by a heel 1b with a rectangular profile.
L'extrémité libre du talon lb est solidaire d'une pointe recourbée 1c qui permet l'introduction de l'outil 1 dans les fentes ou ouvertures des tampons d'égouts 2.The free end of the heel 1b is integral with a curved point 1c which allows the introduction of the tool 1 into the slots or openings of the sewer pads 2.
En arrière de la pointe recourbée 1c et perpendiculairement à l'axe principal de l'outil 1 est soudée une butée cylindrique 1d. Cette butée 1d est prévue solidaire du talon lb de manière que l'opérateur puisse prendre appui sur celle-ci lors de l'utilisation de l'outil 1. Behind the curved point 1c and perpendicular to the main axis of the tool 1 is welded a cylindrical stop 1d. This stop 1d is provided integral with the heel 1b so that the operator can rest on it when using the tool 1.
Le talon lb est prévu d'un poids supérieur à celui de la tige cylindrique la pour constituer une masse suffisante afin de faciliter l'ouverture des tampons d'égouts 2. Au niveau du raccordement entre la tige cylindrique la et le talon lb et suivant l'axe longitudinal de l'outil on a fixé une poignée le qui est de préférence placée au niveau du centre de gravité de l'outil. La position de la poignée le est prévue pour faciliter le transport de l'outil 1, étant donné qu'iL se trouve dans une position d'équilibre. The heel lb is provided with a weight greater than that of the cylindrical rod la to constitute a sufficient mass to facilitate the opening of the sewer pads 2. At the connection between the cylindrical rod la and the heel lb and following the longitudinal axis of the tool is fixed a handle which is preferably placed at the center of gravity of the tool. The position of the handle is provided to facilitate the transport of the tool 1, since iL is in an equilibrium position.
L'extrémité de la tige la opposée au talon ld est pourvue d'une pointe if qui permet à l'utilisateur de dégager le pourtour des tampons d'égouts 2. The end of the rod opposite to the heel 1d is provided with an if point which allows the user to clear the periphery of the sewer pads 2.
Un manchon 1g solidaire d'un crochet 1h est introduit autour de la tige cylindrique la jusqu'à ce qu'il vienne en butée contre la poignée le. Le manchon 1q permet à l'utilisateur, lorsque le tampon d'égout 2 se trouve en position stable à l'intérieur de son cadre 2a (fig. 4), de pouvoir l'accrocher et le retirer. A sleeve 1g integral with a hook 1h is introduced around the cylindrical rod la until it comes into abutment against the handle le. The sleeve 1q allows the user, when the sewer pad 2 is in a stable position inside its frame 2a (fig. 4), to be able to hang it and remove it.
On a représenté par exemple en fig. 2 à 5 les différentes phases d'utilisation de l'outil 1 décrit précédemment. There is shown for example in FIG. 2 to 5 the different phases of using the tool 1 described above.
L'utilisateur introduit la pointe lc dans la fente du tampon 2 prévue à cet effet, comme représenté en fig. 2. Pour faciliter cette introduction, l'utilisateur peut appuyer à l'aide de son pied sur la butée cylindrique id pour avoir plus de force. The user introduces the tip lc into the slot of the buffer 2 provided for this purpose, as shown in FIG. 2. To facilitate this introduction, the user can press with his foot on the cylindrical stop id to have more force.
Ensuite, l'utilisateur bascule l'outil 1 en direction du sol pour prendre appui sur la butée lb en vue de soulever le tampon d'égout 2 (fig. 3). Then, the user tilts the tool 1 in the direction of the ground to rest on the stop lb in order to raise the sewer plug 2 (fig. 3).
Le basculement de l'outil 1 en direction du sol est suffisant pour soulever et placer le tampon 2 dans sa position stable à l'intérieur de son cadre 2a. Lorsque le tampon 2 se trouve dans sa position stable, l'utilisateur peut le retirer à l'aide de l'outil 1 lorsque celui-ci est muni de son crochet 1g. The tilting of the tool 1 towards the ground is sufficient to lift and place the pad 2 in its stable position inside its frame 2a. When the pad 2 is in its stable position, the user can remove it using the tool 1 when the latter is provided with its hook 1g.
Lorsque l'utilisateur veut replacer le tampon d'égout 2 à l'intérieur de son cadre 2a, il retourne l'outil 1 et utilise la pointe recourbée ic comme crochet afin de faire pivoter le tampon 2 (fig. 5). When the user wants to replace the sewer pad 2 inside its frame 2a, he turns over the tool 1 and uses the curved point ic as a hook in order to rotate the pad 2 (fig. 5).
Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
