Description

La présente invention se rapporte d'une manière générale à un ensemble de tampon-cadre destiné à obturer un regard de chaussée ou de trottoir par exemple.The present invention relates generally to a frame buffer assembly intended to close a manhole or sidewalk for example.

Elle vise plus particulièrement un dispositif perfectionné de verrouillage du tampon sur le cadre.It relates more particularly to an improved device for locking the buffer on the frame.

On connaît déjà, d'après le document FR-A-2481337 un dispositif de verrouillage d'un tampon sur un cadre, comprenant une oreille solidaire du cadre, un doigt solidaire du tampon et apte à pénétrer dans l'oreille et à coopérer avec un bec de l'oreille pour empêcher le soulèvement du tampon, et une palette qui est articulée sur un axe horizontal prolongeant le doigt et qui est apte à pénétrer dans l'oreille et à pivoter et se translater dans celle-ci pour assurer le blocage du tampon sur le cadre.Already known from document FR-A-2481337 a device for locking a tampon on a frame, comprising an ear secured to the frame, a finger secured to the tampon and able to penetrate into the ear and to cooperate with an ear beak to prevent lifting of the tampon, and a pallet which is articulated on a horizontal axis extending the finger and which is able to penetrate into the ear and to pivot and translate therein to ensure blocking stamp on the frame.

Dans ce dispositif, l'alésage prévu sur la palette et coopérant avec l'axe pour permettre le pivotement de ladite palette, était un alésage fermé radialement. Ceci veut dire que la palette devait être enfilée sur l'axe préalablement au montage du tampon sur le cadre.In this device, the bore provided on the pallet and cooperating with the axis to allow the pivoting of said pallet, was a bore closed radially. This means that the pallet had to be threaded on the axis before mounting the pad on the frame.

Or, le montage du tampon sur le cadre exigeant l'insertion de la palette dans l'oreille, il fallait effectuer une manoeuvre de tâtonnement sur la palette pour cette insertion, ce qui était parfois délicat et pénible, compte tenu du poids du tampon.However, the mounting of the pad on the frame requiring the insertion of the pallet in the ear, it was necessary to perform a trial and error maneuver on the pallet for this insertion, which was sometimes delicate and painful, given the weight of the pad.

Aussi, la présente invention a pour but de remédier à cet inconvénient en proposant un dispositif de verrouillage qui permet un montage immédiat du tampon sur le cadre.Also, the present invention aims to remedy this drawback by providing a locking device which allows immediate mounting of the buffer on the frame.

A cet effet, l'invention a pour objet un dispositif perfectionné de verrouillage d'un tampon sur un cadre, pour un regard de chaussée ou analogue, du type comprenant une oreille solidaire du cadre, un doigt solidaire du tampon et apte à pénétrer dans l'oreille et à coopérer avec un bec de l'oreille pour empêcher le soulèvement du tampon, et une palette qui est articulée sur un axe horizontal prolongeant le doigt et qui est apte à pénétrer dans l'oreille et à pivoter et se translater dans celle-ci pour assurer le blocage du tampon sur le cadre, caractérisé en ce que l'alésage prévu sur la palette et coopérant avec l'axe est un alésage ouvert ou débouchant radialement pour mettre le montage de la palette sur l'axe après que ledit axe ait été introduit dans l'oreille.To this end, the subject of the invention is an improved device for locking a tampon on a frame, for a manhole cover or the like, of the type comprising an ear secured to the frame, a finger secured to the tampon and capable of penetrating into and to cooperate with an ear beak to prevent lifting of the tampon, and a pallet which is articulated on a horizontal axis extending the finger and which is able to penetrate the ear and pivot and translate in this to ensure the blocking of the buffer on the frame, characterized in that the bore provided on the pallet and cooperating with the axis is an open bore or opening radially to put the assembly of the pallet on the axis after said axis was introduced into the ear.

On comprend donc que l'opération de montage du tampon sur le cadre sera grandement facilitée, par le fait que, lors de la pose du tampon sur le cadre, le doigt associé à ce tampon sera facilement insérable dans l'oreille du cadre, ce après quoi, on pourra facilement monter par son alésage débouchant radialement, la palette sur ledit axe.It is therefore understood that the operation of mounting the pad on the frame will be greatly facilitated, by the fact that, when the pad is placed on the frame, the finger associated with this pad will be easily inserted into the ear of the frame, this after which, one can easily mount by its bore opening radially, the pallet on said axis.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés dans lesquels :

  • les figures 1 et 2 sont des vues partielles en perspective du cadre et du tampon ;
  • les figures 3 et 4 sont des vues en perspective de la palette sous deux angles différents ;
  • les figures 5 et 6 sont des vues partielles en coupe suivant la ligne V-V de la figure 1 et montrent la palette respectivement en position verticale de mise en place dans l'oreille du cadre, et en position horizontale de blocage ;
  • les figures 7 et 8 sont des vues en perspective partielles montrant la palette respectivement dans la phase de mise en place, et dans sa position rabattue de blocage.
Other characteristics and advantages of the invention will appear more clearly in the detailed description which follows and refers to the attached drawings in which:
  • Figures 1 and 2 are partial perspective views of the frame and the pad;
  • Figures 3 and 4 are perspective views of the pallet from two different angles;
  • Figures 5 and 6 are partial sectional views along the line VV of Figure 1 and show the pallet respectively in the vertical position of installation in the ear of the frame, and in the horizontal locking position;
  • Figures 7 and 8 are partial perspective views showing the pallet respectively in the implementation phase, and in its folded locking position.

En se reportant aux dessins, on voit un cadre 2 qui peut être noyé dans le matériau d'une chaussée par exemple et sur lequel peut être monté par emboîtement un tampon ou couvercle 3.Referring to the drawings, we see a frame 2 which can be embedded in the material of a roadway for example and on which can be mounted by fitting a pad or cover 3.

Le tampon 3 est radialement muni d'un doigt 4 se prolongeant par un axe horizontal 8.The pad 3 is radially provided with a finger 4 extending by a horizontal axis 8.

Le doigt 4 avec son axe 8 peut être reçu dans une oreille 6 à la périphérie extérieure du cadre 2.The finger 4 with its axis 8 can be received in an ear 6 at the outer periphery of the frame 2.

Cette oreille comporte deux parois repérées en 19 et 20, ainsi qu'un bec 5 dont la face inférieure 5a (voir figure 5) peut coopérer avec la face 4a du doigt 4, pour empêcher le soulèvement du tampon 3, comme on l'expliquera plus loin.This ear has two walls identified in 19 and 20, as well as a spout 5 whose lower face 5a (see FIG. 5) can cooperate with the face 4a of the finger 4, to prevent the lifting of the tampon 3, as will be explained. further.

L'oreille 6 est intérieurement munie d'un redan 28 sur lequel peut prendre appui une palette 7, laquelle palette peut être montée articulée sur l'axe horizontal 8.The ear 6 is internally provided with a step 28 on which a pallet 7 can rest, which pallet can be mounted articulated on the horizontal axis 8.

Comme on le voit bien sur les figures 3 et 4 notamment, et conformément à une caractéristique essentielle de l'invention, la palette 7 comporte un alésage 13 qui débouche radialement, c'est-à-dire qui est ouvert et qui peut par conséquent être monté sur l'axe 8, après que ledit axe ait été inséré dans l'oreille 6, c'est-à-dire après que le tampon 3 ait été monté sur le cadre 2.As can be seen clearly in FIGS. 3 and 4 in particular, and in accordance with an essential characteristic of the invention, the pallet 7 has a bore 13 which opens radially, that is to say which is open and which can consequently be mounted on the axis 8, after the said axis has been inserted into the ear 6, that is to say after the pad 3 has been mounted on the frame 2.

Comme décrit dans le document FR-A-2481337, la palette 7 comporte une nervure 15, et un nez 22 susceptible de coopérer avec un logement 23 possédant une forme complémentaire de celle du nez 22, de sorte que, lorsque la palette 7, après montage sur l'axe 8, sera basculée, comme on le voit sur les figures 7 et 8, ladite palette, par coopération du nez 22 et du logement 23 procurera une rotation du tampon 3 par rapport au cadre 2 pour réaliser ainsi le passage du doigt 4 sous le bec 5, c'est-à-dire finalement le verrouillage du tampon sur le cadre.As described in document FR-A-2481337, the pallet 7 has a rib 15, and a nose 22 capable of cooperating with a housing 23 having a shape complementary to that of the nose 22, so that, when the pallet 7, after mounting on the axis 8, will be tilted, as seen in Figures 7 and 8, said pallet, by cooperation of the nose 22 and the housing 23 will provide a rotation of the buffer 3 relative to the frame 2 to thereby achieve the passage of the finger 4 under the spout 5, that is to say finally the locking of the buffer on the frame.

La palette 7 peut encore comporter d'autres éléments qui ne font pas partie de la présente invention et qui sont décrits dans le document précité auquel on pourra se reporter.Pallet 7 may also include other elements which are not part of the present invention and which are described in the aforementioned document to which reference may be made.

Pour une meilleure compréhension de l'invention, on expliquera très brièvement ci-après comment fonctionne le dispositif de verrouillage qui vient d'être décrit.For a better understanding of the invention, we will explain very briefly below how the locking device which has just been described works.

Le tampon 3 est posé sur le cadre 2, ce qui ne présente aucune difficulté. En effet, il suffira que le tampon 3 soit convenablement orienté pour que le doigt 4 avec son axe 8 se situe au droit de l'oreille 6.The pad 3 is placed on the frame 2, which presents no difficulty. Indeed, it will suffice that the tampon 3 is suitably oriented so that the finger 4 with its axis 8 is located in line with the ear 6.

Cette opération étant faite, on monte à la main, comme on le voit sur la figure 5, la palette 7 sur l'axe 8 par son alésage ouvert 13, dans l'oreille 6.This operation having been made, the pallet 7 is mounted by hand, as can be seen in FIG. 5, on the axis 8 by its open bore 13, in the ear 6.

On fait ensuite pivoter la palette 7 autour de son axe 8 suivant le sens de la flèche repérée F sur la figure 5.The pallet 7 is then pivoted around its axis 8 in the direction of the arrow marked F in FIG. 5.

Ce pivotement, du fait de la coopération du nez 22 avec le logement 23, va provoquer une translation de la palette 7 dans le sens de la flèche repérée G sur la figure 6, de sorte que la face 4a du doigt 4 va venir en dessous de la face 5a du bec 5. Ainsi, le tampon 3 sera verrouillé sur le cadre 2 par l'intermédiaire du doigt 4 et du bec 5 qui sont amenés en position de coopération grâce au pivotement de la palette 7.This pivoting, due to the cooperation of the nose 22 with the housing 23, will cause a translation of the pallet 7 in the direction of the arrow marked G in Figure 6, so that the face 4a of the finger 4 will come below of the face 5a of the spout 5. Thus, the pad 3 will be locked on the frame 2 by means of finger 4 and spout 5 which are brought into the cooperation position by pivoting the pallet 7.

Pour effectuer le déverrouillage, il convient tout d'abord de faire pivoter vers le haut la palette 7 à la main ou à l'aide d'un outil introduit dans le logement 30.To unlock, it is first necessary to rotate the pallet 7 upwards by hand or using a tool inserted in the housing 30.

Ceci étant fait, le doigt 4 du tampon 3 reste prisonnier du bec 5. Pour le dégager, on introduit un outil entre la paroi 20 de l'oreille 6 et la face supérieure de la palette 7 qui se trouve en position verticale. Ainsi, la palette 7 sera translatée suivant un sens inverse à celui de la flèche G, de sorte que le tampon 3 sera entraîné en rotation par rapport au cadre 2, ce qui dégagera le doigt 4 du dessous du bec 5.This being done, the finger 4 of the pad 3 remains trapped in the spout 5. To release it, a tool is inserted between the wall 20 of the ear 6 and the upper face of the pallet 7 which is in a vertical position. Thus, the pallet 7 will be translated in a direction opposite to that of the arrow G, so that the pad 3 will be driven in rotation relative to the frame 2, which will release the finger 4 from below the spout 5.

La palette 7 pourra alors être extraite de l'axe 8, et le tampon 3 extrait du cadre 2.The pallet 7 can then be extracted from the axis 8, and the buffer 3 extracted from the frame 2.

Il est à noter que l'échappement du doigt 4 au bec 5 pourrait être obtenu alors que la palette 7 a déjà été extraite de l'axe 8. Dans ce cas, l'outil coopérerait avec la paroi 20 de l'oreille et l'axe 8 directement.It should be noted that the escape from finger 4 to spout 5 could be obtained while the pallet 7 has already been extracted from the axis 8. In this case, the tool would cooperate with the wall 20 of the ear and the 'axis 8 directly.

On a donc réalisé suivant l'invention un dispositif de verrouillage d'un tampon sur un cadre qui facilite grandement le montage du tampon sur le cadre, c'est-à-dire sans aucune gêne procurée le système commandant le verrouillage, lequel système assure néanmoins un verrouillage efficace.We have therefore produced according to the invention a device for locking a pad on a frame which greatly facilitates the mounting of the pad on the frame, that is to say without any discomfort provided by the system controlling the locking, which system ensures nevertheless effective locking.

L'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.The invention is in no way limited to the embodiment described and illustrated which has been given only by way of example.
