Description

La présente invention concerne un ensemble de tampons pour un dispositif de voirie, du type comprenant un premier tampon et un second tampon,
le premier tampon comportant un premier côté de liaison et un premier voile qui s'étend selon un premier plan de voile et qui comprend une surface supérieure, et
le second tampon comportant un second côté de liaison adjacent au premier côté de liaison et un second voile qui s'étend selon un second plan de voile et qui comprend une surface supérieure.The present invention relates to a set of buffers for a road device, of the type comprising a first buffer and a second buffer,
the first buffer having a first connecting side and a first web extending in a first sail plane and comprising an upper surface, and
the second buffer having a second link side adjacent to the first link side and a second sail that extends in a second sail plane and includes a top surface.

Un tel ensemble est connu de FR2937061 .Such a set is known to FR2937061 .

On connaît dans l'état de la technique des dispositifs de voirie, tels que des regards d'accès à des installations de télécommunication, comprenant un cadre et deux tampons triangulaires.In the state of the art, roadway devices are known, such as manholes for access to telecommunication installations, comprising a frame and two triangular pads.

Dans un premier cas, les tampons ne sont pas reliés, sont logés individuellement dans le cadre et doivent être mis individuellement dans la position ouverte afin de permettre à un opérateur d'accéder aux installations souterraines recouvertes par le regard d'accès. Ceci nécessite la manipulation de deux tampons.In the first case, the buffers are not connected, are housed individually in the frame and must be placed individually in the open position to allow an operator to access the underground facilities covered by the access view. This requires the manipulation of two buffers.

Dans un second cas, les deux tampons sont reliés l'un à l'autre par des moyens de liaison très « lâches », tels que deux axes goupillés, qui laissent un grand jeu de débattement entre les deux tampons. Ces moyens de liaison nécessitent deux clés de préhension et deux opérateurs afin d'ouvrir ou de fermer le regard d'accès. De plus, ces moyens de liaison créent des difficultés de soulèvement et des risques de coincement des tampons dans le cadre.In a second case, the two buffers are connected to each other by very "loose" connection means, such as two pinned axes, which leave a large clearance clearance between the two buffers. These connecting means require two gripping keys and two operators to open or close the access view. In addition, these connecting means create difficulties of lifting and risks of jamming of the buffers in the frame.

Il existe également des tampons quadrilatères. Dans la configuration fermée du regard d'accès et du fait que ces tampons présentent quatre points d'appui, ils peuvent boiter dans le cadre lorsque des véhicules circulent sur le tampon, ce qui génère du bruit.There are also quadrilateral buffers. In the closed configuration of the access window and the fact that these buffers have four points of support, they can limp in the frame when vehicles travel on the buffer, which generates noise.

L'invention a pour but de proposer un ensemble de tampons qui permette une manipulation simple et économique du regard d'accès.The invention aims to provide a set of buffers that allows a simple and economical manipulation of the access view.

Un autre but de l'invention est de fournir un ensemble de tampons pouvant s'ouvrir suivant des sens d'ouverture différents.Another object of the invention is to provide a set of buffers that can open in different directions of opening.

Un autre but de l'invention est de fournir un ensemble de tampons qui ne génère pas de bruit d'instabilité lors du passage de véhicules sur le regard d'accès.Another object of the invention is to provide a set of buffers that does not generate instability noise during the passage of vehicles on the access door.

Un autre but de l'invention est la fabrication économique et simple de l'ensemble de tampons.Another object of the invention is the economical and simple manufacture of the buffer assembly.

A cet effet, l'invention a pour objet un ensemble de tampons, tel qu'indiqué ci-dessus, caractérisé en ce que l'ensemble de tampons comprend des moyens de liaison reliant le premier tampon au second tampon le long des premier et second côtés de liaison,

La figure 1 montre un dispositif de voirie selon l'invention, désigné par la référence générale 2. Le dispositif de voirie 2 est un regard d'accès à des installations de télécommunication. En variante, le dispositif de voirie 2 est un regard d'accès à d'autres installations souterraines, par exemple un regard de chaussée d'accès à des canalisations d'eau.The figure 1 shows a road device according to the invention, designated by the general reference 2. The road device 2 is a view of access to telecommunications facilities. In a variant, the road device 2 is a view of access to others underground installations, for example a manhole of access to water pipes.

Le dispositif de voirie 2 comprend un cadre 4 et un ensemble de tampons 6.The road device 2 comprises a frame 4 and a set of pads 6.

Les expressions « supérieure » et « inférieure » seront utilisées par la suite par rapport à l'orientation habituelle du dispositif de voirie 2, le côté « supérieur » étant dirigé vers l'extérieur de l'installation et le côté « inférieur » étant dirigé vers l'intérieur de l'installation.The terms "upper" and "lower" will be used later in relation to the usual orientation of the road device 2, the "upper" side being directed towards the outside of the installation and the "lower" side being directed towards the interior of the installation.

Le cadre 4 est fabriqué d'une seule pièce, notamment en fonte. En variante, il peut aussi être constitué de plusieurs pièces assemblées de diverses manières, par exemple par soudure.The frame 4 is made in one piece, including cast iron. Alternatively, it may also consist of several parts assembled in various ways, for example by welding.

Le cadre 4 comporte une base de cadre 8, qui s'étend selon un plan de base P-P, et une paroi de cadre 10 s'étendant perpendiculairement par rapport à la base de cadre 8. Le plan de cadre P-P est généralement dirigé parallèlement au sol dans lequel le dispositif de voirie 2 est installé.The frame 4 comprises a frame base 8, which extends along a base plane PP, and a frame wall 10 extending perpendicularly with respect to the frame base 8. The frame plane PP is generally directed parallel to the ground in which the road device 2 is installed.

Le cadre 4 comporte un premier jeu de surfaces d'appui 12, 14, 16 pour un tampon ainsi qu'un second jeu de surfaces d'appui 18, 20, 22 pour un autre tampon. Chaque surface d'appui 12, 14, 16, 18, 20, 22, 24 s'étend sensiblement parallèlement au plan de cadre P-P. Deux surfaces d'appui 12, 16 du premier jeu de surfaces d'appui sont adjacentes à l'une des surfaces d'appui 18, 22 du second jeu de surfaces d'appui. Les deux autres surfaces d'appui 14 et 20 des jeux de surfaces d'appui sont situées dans des coins opposés du cadre 4.The frame 4 comprises a first set of bearing surfaces 12, 14, 16 for a buffer and a second set of bearing surfaces 18, 20, 22 for another buffer. Each bearing surface 12, 14, 16, 18, 20, 22, 24 extends substantially parallel to the P-P frame plane. Two bearing surfaces 12, 16 of the first set of bearing surfaces are adjacent to one of the bearing surfaces 18, 22 of the second set of bearing surfaces. The other two bearing surfaces 14 and 20 of the bearing surface play are located in opposite corners of the frame 4.

Toutes les surfaces d'appui sont idéalement coplanaires. En raison des tolérances de fabrication et de la recherche d'une stabilité maximale sous trafic routier intense, à travers un triangle de sustentation le plus grand possible, elles peuvent toutefois être décalées les unes des autres d'un décalage maximal déterminé, qui est par exemple 3 mm. Le décalage maximal déterminé est la distance, mesurée perpendiculairement au plan de cadre P-P, entre les deux surfaces d'appui ayant la plus grande distance mutuelle perpendiculaire au plan de cadre P-P. Ce décalage peut aussi être un décalage angulaire de l'ordre de quelques degrés au maximum, par exemple 3 degrés, avec effet de stabilisation du tampon vers le centre géométrique du regard d'accès.All bearing surfaces are ideally coplanar. Due to manufacturing tolerances and the search for maximum stability under heavy road traffic, through a triangle as large as possible, they can however be offset from each other by a given maximum offset, which is example 3 mm. The maximum offset determined is the distance, measured perpendicularly to the P-P frame plane, between the two bearing surfaces having the greatest mutual distance perpendicular to the P-P frame plane. This offset can also be an angular offset of the order of a few degrees at most, for example 3 degrees, with stabilizing effect of the buffer towards the geometric center of the access window.

L'ensemble de tampons 6 comprend un premier tampon 40 et un second tampon 42. Le premier 40 et le second 42 tampon sont fabriqués d'une seule pièce, notamment en fonte.The set of pads 6 comprises a first buffer 40 and a second buffer 42. The first 40 and the second 42 buffer are made in one piece, including cast iron.

L'ensemble de tampons 6 est déplaçable par rapport au cadre 4 entre une position fermée, dans laquelle l'ensemble de tampons 6 repose dans le cadre et les plans de voile T1-T1 et T2-T2 sont généralement parallèles au plan de cadre P-P (voir ci après), et une position ouverte, dans laquelle l'ensemble de tampons 6 libère l'ouverture du cadre 4 et est disposé hors du cadre 4.The set of pads 6 is movable relative to the frame 4 between a closed position, in which the set of pads 6 rests in the frame and the sail planes T1-T1 and T2-T2 are generally parallel to the frame plane PP (see below), and a open position, in which the set of pads 6 releases the opening of the frame 4 and is arranged outside the frame 4.

Les premier 40 et second 42 tampons sont identiques. A l'état monté de l'ensemble de tampons 6, le second tampon 42 est tourné de 180° par rapport au premier tampon 40 autour d'un axe central de symétrie C-C (Figure 6).The first 40 and second 42 buffers are identical. In the mounted state of the buffer assembly 6, the second buffer 42 is rotated 180 ° with respect to the first buffer 40 about a central axis of symmetry CC ( Figure 6 ).

Le premier tampon 40 comporte un premier voile 44 s'étendant selon un premier plan de voile T1-T1 (Figure 6) et comprenant une surface supérieure 46 ainsi qu'une surface inférieure 48.The first buffer 40 comprises a first web 44 extending along a first plane of sail T1-T1 ( Figure 6 ) and comprising an upper surface 46 and a lower surface 48.

Le premier tampon 40 est de forme sensiblement triangulaire rectangle et délimite trois côtés 50, 52, 54. L'un des côtés 54 est un premier côté de liaison, qui sert à relier le premier tampon 40 au second tampon 42 adjacent. En l'occurrence, le premier côté de liaison est l'hypoténuse du triangle rectangle. Chaque côté 50, 52, 54 est formé par un chant du premier voile 44.The first buffer 40 is substantially triangular in shape and defines three sides 50, 52, 54. One side 54 is a first connecting side, which serves to connect the first buffer 40 to the second buffer 42 adjacent. In this case, the first connecting side is the hypotenuse of the right triangle. Each side 50, 52, 54 is formed by a song of the first veil 44.

Le premier tampon 40 comprend trois premières nervures de rigidification 56, 58, 60. Chaque première nervure de rigidification 56, 58, 60 s'étend le long de l'un des côtés 50, 52, 54 sur la surface inférieure du premier voile 44. La nervure de rigidification 60 s'étendant le long du premier côté de liaison est une première nervure de liaison.The first buffer 40 comprises three first stiffening ribs 56, 58, 60. Each first stiffening rib 56, 58, 60 extends along one of the sides 50, 52, 54 on the lower surface of the first web 44. The stiffening rib 60 extending along the first bonding side is a first bonding rib.

Le premier tampon 40 comprend trois premières surfaces d'appui 62, 64, 66 de tampon adaptées pour reposer sur le premier jeu de surfaces d'appui 12, 14, 16 du cadre, lorsque l'ensemble de tampons 6 est dans la position fermée.The first buffer 40 comprises three first bearing surfaces 62, 64, 66 of buffer adapted to rest on the first set of bearing surfaces 12, 14, 16 of the frame, when the set of pads 6 is in the closed position .

Les trois premières surfaces d'appui 62, 64, 66 du premier tampon 40 sont parallèles les unes aux autres et parallèles au premier plan de voile T1-T1. Les trois premières surfaces d'appui 62, 64, 66 de tampon sont idéalement coplanaires. En raison des tolérances de fabrication ou d'une géométrie particulière du regard d'accès, elles peuvent toutefois être décalées les unes des autres. Ce décalage est la distance, mesurée perpendiculairement au premier plan de voile T1-T1, entre les deux premières surfaces d'appui 62, 64, 66 de tampon ayant la plus grande distance mutuelle perpendiculaire au premier plan de voile T1-T1. Elles peuvent aussi être décalées angulairement d'un décalage angulaire maximal déterminé, qui est par exemple de 3 degrés, le décalage angulaire correspondant à l'angle réel des premières surfaces d'appui 62, 64, 66 par rapport à un angle théorique déterminé de construction.The first three bearing surfaces 62, 64, 66 of the first buffer 40 are parallel to each other and parallel to the first sail plane T1-T1. The first three bearing surfaces 62, 64, 66 of buffer are ideally coplanar. Due to the manufacturing tolerances or a particular geometry of the access point, they can however be offset from each other. This offset is the distance, measured perpendicularly to the first plane of sail T1-T1, between the two first bearing surfaces 62, 64, 66 of buffer having the greatest mutual distance perpendicular to the first plane of sail T1-T1. They can also be angularly offset by a predetermined maximum angular offset, which is for example 3 degrees, the angular offset corresponding to the actual angle of the first bearing surfaces 62, 64, 66 with respect to a given theoretical angle of construction.

Le premier tampon 40 définit un premier sens normal SN1, dirigé depuis la surface supérieure 46 perpendiculairement au premier plan de voile T1-T1. Dans la position fermée, le premier sens normal SN1 est donc dirigé perpendiculairement au plan de cadre P-P. Ce premier sens normal SN1 correspond à un sens de soulèvement du premier tampon 40 lors de son retrait du cadre à partir de la position fermée.The first buffer 40 defines a first normal direction SN1, directed from the upper surface 46 perpendicular to the first sail plane T1-T1. In the closed position, the first normal direction SN1 is therefore directed perpendicularly to the frame plane PP. This first normal sense SN1 corresponds to a lifting direction of the first buffer 40 when it is removed from the frame from the closed position.

Le second tampon 42 comporte un second voile 74 s'étendant selon un second plan de voile T2-T2 (Figure 6) et comprenant une surface supérieure 76 ainsi qu'une surface inférieure 78.The second buffer 42 comprises a second web 74 extending along a second plane of sail T2-T2 ( Figure 6 ) and comprising an upper surface 76 and a lower surface 78.

Le second tampon 42 est de forme sensiblement triangulaire rectangle et délimite trois côtés 80, 82, 84. L'un des côtés 84 est un second côté de liaison, qui sert à relier le second tampon 42 au premier tampon 40 adjacent. En l'occurrence, le second côté de liaison est l'hypoténuse du triangle rectangle. Chaque côté 80, 82, 84 est formé par un chant du second voile 74.The second buffer 42 is substantially triangular in shape and defines three sides 80, 82, 84. One of the sides 84 is a second connecting side, which serves to connect the second buffer 42 to the first adjacent buffer 40. In this case, the second connecting side is the hypotenuse of the right triangle. Each side 80, 82, 84 is formed by a song of the second sail 74.

Le second tampon 42 comprend trois secondes nervures de rigidification 86, 88, 90. Chaque seconde nervure de rigidification s'étend le long de l'un des côtés 80, 82, 84 sur la surface inférieure du second voile 74. La nervure de rigidification 90 s'étendant le long du second côté de liaison est une seconde nervure de liaison.The second buffer 42 comprises three second stiffening ribs 86, 88, 90. Each second stiffening rib extends along one of the sides 80, 82, 84 on the lower surface of the second web 74. The stiffening rib 90 extending along the second connecting side is a second connecting rib.

Le second tampon 42 comprend également trois secondes surfaces d'appui 92, 94, 96 de tampon adaptées pour reposer sur le second jeu de surfaces d'appui 18, 20, 22 du cadre 4, lorsque l'ensemble de tampons 6 est dans la position fermée.The second buffer 42 also comprises three second bearing surfaces 92, 94, 96 of buffer adapted to rest on the second set of bearing surfaces 18, 20, 22 of the frame 4, when the buffer assembly 6 is in the closed position.

Les trois secondes surfaces d'appui 92, 94, 96 du second tampon sont parallèles les unes aux autres et parallèles au second plan de voile T2-T2. Les trois surfaces d'appui 92, 94, 96 sont également idéalement coplanaires. En raison des tolérances de fabrication ou d'une géométrie particulière du regard d'accès, elles peuvent toutefois être décalées les unes des autres d'un décalage maximal déterminé, qui est par exemple 3 mm. Le décalage maximal déterminé est la distance, mesurée perpendiculairement au second plan de voile T2-T2, entre les deux secondes surfaces d'appui 92, 94, 96 du second tampon 42 ayant la plus grande distance mutuelle perpendiculaire au second plan de voile T2-T2. Elles peuvent aussi être décalées angulairement d'un décalage angulaire maximal déterminé, qui est par exemple de 3 degrés, le décalage angulaire correspondant à l'angle réel des secondes surfaces d'appui 92, 94, 96 par rapport à un angle théorique déterminé de construction.The three second bearing surfaces 92, 94, 96 of the second buffer are parallel to each other and parallel to the second sail plane T2-T2. The three bearing surfaces 92, 94, 96 are also ideally coplanar. Due to manufacturing tolerances or a particular geometry of the access view, they can however be offset from each other by a given maximum offset, which is for example 3 mm. The maximum offset determined is the distance, measured perpendicular to the second sail plane T2-T2, between the two second bearing surfaces 92, 94, 96 of the second buffer 42 having the greatest mutual distance perpendicular to the second plane of sail T2- T2. They can also be angularly offset by a determined maximum angular offset, which is for example 3 degrees, the angular offset corresponding to the actual angle of the second bearing surfaces 92, 94, 96 with respect to a given theoretical angle of construction.

Le second tampon 42 définit un second sens normal SN2, dirigé depuis la surface supérieure 76 perpendiculairement au second plan de voile T2-T2. Dans la position fermée, le second sens normal SN2 est donc dirigé perpendiculairement au plan de cadre P-P. Ce second sens normal SN2 correspond à un sens de soulèvement du second tampon 42 lors de son retrait du cadre à partir de la position fermée.The second buffer 42 defines a second normal direction SN2, directed from the upper surface 76 perpendicular to the second sail plane T2-T2. In the closed position, the second normal direction SN2 is thus directed perpendicular to the P-P frame plane. This second normal direction SN2 corresponds to a lifting direction of the second buffer 42 when it is withdrawn from the closed position.

L'ensemble de tampons 6 comprend des moyens de liaison 100 reliant le premier tampon 40 au second tampon 42 le long des premier 54 et second 84 côtés de liaison.The buffer assembly 6 includes connecting means 100 connecting the first buffer 40 to the second buffer 42 along the first 54 and second 84 connecting sides.

A cet effet, les moyens de liaison 100 comprennent des moyens de charnière 102 (Figure 7) définissant un axe de charnière X-X entre les premier et second tampons 40, 42 et ceci le long des premier 54 et second 84 côtés de liaison. Les moyens de charnière 102 sont adaptés pour guider les deux tampons 40, 42 l'un par rapport à l'autre autour de l'axe de charnière X-X, de préférence avec un jeu radial déterminé par rapport à l'axe X-X.For this purpose, the connecting means 100 comprise hinge means 102 ( Figure 7 ) defining a hinge axis XX between the first and second buffers 40, 42 and this along the first 54 and second 84 connecting sides. The hinge means 102 are adapted to guide the two buffers 40, 42 relative to each other about the hinge axis XX, preferably with a radial clearance determined with respect to the axis XX.

Les moyens de charnière 102 comprennent deux premières saillies 104 disposées sur le premier tampon 40, dirigées vers le second tampon 42 et adaptées pour s'opposer à un déplacement relatif du premier tampon 40 par rapport au second tampon 42 dans le premier sens normal SN1 radialement par rapport à l'axe de charnière X-X.The hinge means 102 comprise two first projections 104 disposed on the first buffer 40, directed towards the second buffer 42 and adapted to oppose a relative displacement of the first buffer 40 relative to the second buffer 42 in the first normal direction SN1 radially. relative to the hinge axis XX.

Chaque première saillie 104 est fabriquée d'un seul tenant avec le premier tampon 40 et est de préférence venue de matière avec ce premier tampon 40, par exemple par fonderie. En variante, chaque première saillie 104 est solidaire du premier tampon 40, et rapportée à ce tampon 40, par exemple par soudage. Encore en variante, chaque première saillie 104 est formée par un organe rapporté et fixé d'une manière libérable au premier tampon 40, tel qu'un boulon, une goupille, un clip, une clavette ou tout autre élément permettant de solidariser entre eux les deux tampons 40, 42 tout en laissant les degrés de liberté nécessaires au bon fonctionnement.Each first protrusion 104 is made in one piece with the first pad 40 and is preferably integral with this first pad 40, for example by casting. Alternatively, each first projection 104 is integral with the first buffer 40, and reported to this buffer 40, for example by welding. In another variant, each first projection 104 is formed by an insert member and releasably fixed to the first buffer 40, such as a bolt, a pin, a clip, a key, or any other element making it possible to two buffers 40, 42 while leaving the degrees of freedom necessary for proper operation.

Les premières saillies 104 sont disposées sur la première nervure de liaison 60, sont adjacentes à la première surface inférieure 48 et sont notamment alignées axialement selon l'axe de charnière X-X. Lorsque les deux tampons 40, 42 sont assemblés, les premières saillies 104 s'appliquent sur la seconde surface inférieure 78.The first projections 104 are disposed on the first connecting rib 60, are adjacent to the first lower surface 48 and are in particular axially aligned along the axis of hinge X-X. When the two pads 40, 42 are assembled, the first projections 104 are applied to the second lower surface 78.

Les premières saillies 104 sont disposées respectivement à des distances D1 et D2 de l'axe central C-C, mesurées le long de l'axe de charnière X-X. Les distances D1 et D2 diffèrent l'une de l'autre au moins de la largeur L des premières saillies 104 mesurée le long de l'axe de charnière X-X. Les premières saillies 104 sont donc disposées de telle sorte que, lorsque le tampon 40 est tourné de 180° depuis une position initiale autour de l'axe central de symétrie C-C, les premières saillies 104 ne chevauchent pas les premières saillies 104 à la position initiale.The first projections 104 are respectively disposed at distances D1 and D2 of the central axis CC, measured along the hinge axis XX. The distances D1 and D2 differ from each other by at least the width L of the first projections 104 measured along the hinge axis XX. The first projections 104 are thus arranged such that, when the pad 40 is rotated 180 ° from an initial position around the central axis of symmetry CC, the first projections 104 do not overlap the first projections 104 at the initial position. .

Le premier voile 44 est muni d'un évidement 106 à l'emplacement de chaque première saillie 104 qui dégage entièrement chaque première saillie 104 dans le premier sens normal SN1.The first web 44 is provided with a recess 106 at the location of each first projection 104 which completely disengages each first projection 104 in the first normal direction SN1.

Les moyens de charnière 102 comprennent deux secondes saillies 108 disposées sur le second tampon 42, dirigées vers le premier tampon 40 et adaptées pour s'opposer à un déplacement relatif du second tampon 42 par rapport au premier tampon 40 dans le second sens normal SN2 radialement par rapport à l'axe de charnière X-X.The hinge means 102 comprise two second projections 108 disposed on the second buffer 42, directed towards the first buffer 40 and adapted to oppose a relative displacement of the second buffer 42 relative to the first buffer 40 in the second normal direction SN2 radially. relative to the hinge axis XX.

Chaque seconde saillie 108 est fabriquée d'un seul tenant avec le second tampon 42 et est de préférence venue de matière avec ce second tampon 42, par exemple par fonderie. En variante, chaque seconde saillie 108 est solidaire du second tampon 42, et rapportée à ce tampon 42, par exemple par soudage. Encore en variante, chaque seconde saillie 108 est formée par un organe rapporté et fixé d'une manière libérable au second tampon 42, tel qu'un boulon, une goupille, un clip, une clavette ou tout autre élément permettant de solidariser entre eux les deux tampons 40, 42 tout en laissant les degrés de liberté nécessaires au bon fonctionnement.Each second projection 108 is made in one piece with the second buffer 42 and is preferably integral with this second buffer 42, for example by foundry. Alternatively, each second projection 108 is integral with the second buffer 42, and reported to this buffer 42, for example by welding. Still alternatively, each second projection 108 is formed by an insert member and releasably secured to the second buffer 42, such as a bolt, a pin, a clip, a key or any other element to secure between them the two buffers 40, 42 while leaving the degrees of freedom necessary for proper operation.

Les secondes saillies 108 sont disposées sur la seconde nervure de liaison 90, sont adjacentes à la seconde surface inférieure 78 et sont notamment alignées axialement selon l'axe de charnière X-X. Lorsque les deux tampons 40, 42 sont assemblés, les secondes saillies 108 s'appliquent sur la première surface inférieure 48.The second projections 108 are disposed on the second connecting rib 90, are adjacent to the second lower surface 78 and are in particular axially aligned along the axis of hinge X-X. When the two pads 40, 42 are assembled, the second projections 108 are applied to the first lower surface 48.

Les secondes saillies 108 sont disposées respectivement à des distances D1 et D2 de l'axe central C-C, mesurées le long de l'axe de la charnière X-X. Les distances D1 et D2 diffèrent l'une de l'autre au moins de la largeur L des secondes saillies 108 mesurée le long de l'axe de charnière X-X. Les secondes saillies 108 sont donc disposées de telle sorte que, lorsque le tampon 42 est tourné de 180° depuis une position initiale autour de l'axe central de symétrie C-C, les secondes saillies 108 ne chevauchent pas les secondes saillies 108 à la position initiale.The second projections 108 are respectively disposed at distances D1 and D2 of the central axis CC, measured along the axis of the hinge XX. The distances D1 and D2 differ from each other by at least the width L of the second projections 108 measured along the hinge axis XX. The second projections 108 are thus arranged such that, when the pad 42 is rotated 180 ° from an initial position about the central axis of symmetry CC, the second projections 108 do not overlap the second projections 108 at the initial position .

Le second voile 74 est muni d'un évidement 110 à l'emplacement de chaque seconde saillie 108 qui dégage entièrement chaque seconde saillie 108 dans le second sens normal SN2.The second web 74 is provided with a recess 110 at the location of each second projection 108 which fully disengages each second projection 108 in the second normal direction SN2.

L'ensemble de tampons 6 définit une configuration alignée, dans laquelle le premier plan de voile T1-T1 et le second plan de voile T2-T2 sont coplanaires. L'ensemble de tampons 6 définit également un angle de brisure qui est l'angle de décalage du premier plan de voile T1-T1 par rapport au second plan de voile T2-T2 autour de l'axe de charnière X-X en partant de la configuration alignée.The buffer assembly 6 defines an aligned configuration, wherein the first sail plane T1-T1 and the second sail plane T2-T2 are coplanar. The buffer assembly 6 also defines a break angle which is the offset angle of the first sail plane T1-T1 with respect to the second sail plane T2-T2 about the hinge axis XX, starting from the configuration aligned.

L'ensemble de tampons 6 comprend en outre des premiers moyens de butée 112 adaptés pour limiter l'angle de brisure (Figure 6) du second tampon 42 par rapport au premier tampon 40 autour de l'axe de charnière X-X à un premier angle limite α1 et ceci dans un sens de rotation dirigeant les deux surfaces supérieures 46, 76 l'une vers l'autre. Le premier angle limite α1 est égal ou inférieur à 5° et est compris entre 1° et 5°.The buffer assembly 6 further comprises first stop means 112 adapted to limit the break angle ( Figure 6 ) of the second buffer 42 relative to the first buffer 40 about the hinge axis XX at a first limit angle α1 and this in a direction of rotation directing the two upper surfaces 46, 76 towards each other. The first limiting angle α1 is equal to or less than 5 ° and is between 1 ° and 5 °.

Les premiers moyens de butée 112 s'opposent donc à une séparation des deux nervures de liaison 60, 90 au-delà d'une distance prédéterminée perpendiculairement à l'axe de charnière X-X. Cette distance prédéterminée est par exemple de 3 mm.The first stop means 112 therefore oppose a separation of the two connecting ribs 60, 90 beyond a predetermined distance perpendicular to the hinge axis X-X. This predetermined distance is for example 3 mm.

Les premiers et seconds tampons 40, 42 sont libres en rotation autour de l'axe de charnière X-X entre la configuration alignée de l'ensemble de tampons 6 et la configuration dans laquelle le second tampon 42 forme par rapport au premier tampon 40 le premier angle limite.The first and second buffers 40, 42 are free to rotate about the hinge axis XX between the aligned configuration of the buffer assembly 6 and the configuration in which the second buffer 42 forms with respect to the first buffer 40 the first limiting angle.

Les premiers moyens de butée 112 comprennent un élément de butée 114 comportant deux surfaces de butée 116, 118 dirigées l'une vers l'autre. En l'occurrence, l'élément de butée 114 est un boulon ayant une vis et un écrou. Les deux surfaces de butée 116, 118 s'appliquent sur les nervures de liaison 60, 90.The first stop means 112 comprise an abutment member 114 having two abutment surfaces 116, 118 directed toward each other. In this case, the stop member 114 is a bolt having a screw and a nut. The two abutment surfaces 116, 118 are applied to the connecting ribs 60, 90.

A cet effet, chaque nervure de liaison 60, 90 comporte un trou traversant 120 qui est traversé par l'élément de butée 114. Le trou traversant 120 est disposé approximativement au milieu de la hauteur de la nervure de liaison 60, 90, donc dans la fibre neutre. De plus, le trou traversant 120 est disposé au milieu de la longueur axiale du côté de liaison 54, 84.For this purpose, each connecting rib 60, 90 has a through hole 120 which is traversed by the abutment element 114. The through hole 120 is disposed approximately in the middle of the height of the connecting rib 60, 90, so in the neutral fiber. In addition, the through hole 120 is disposed in the middle of the axial length of the connecting side 54, 84.

Les moyens de butée 112 sont réglables, de telle sorte que le premier angle limite α1 est réglable. Dans le cas présent, ce réglage est obtenu en déplaçant l'écrou par rapport à la vis.The abutment means 112 are adjustable, so that the first limiting angle α1 is adjustable. In this case, this adjustment is obtained by moving the nut relative to the screw.

En variante, l'élément de butée 114 peut comprendre une goupille. Egalement en variante, les premiers moyens de butée 112 comprennent des moyens d'amortissement, tels que des éléments amortisseurs en matière plastique (non-représentés) disposés entre l'élément de butée 114 et les nervures de liaison 60, 90.Alternatively, the abutment member 114 may comprise a pin. Also alternatively, the first abutment means 112 comprise damping means, such as plastic damping elements (not shown) disposed between the abutment member 114 and the connecting ribs 60, 90.

L'ensemble de tampons 6 comporte par ailleurs des seconds moyens de butée 122 adaptés pour limiter l'angle de brisure du second tampon 42 par rapport au premier tampon 40 autour de l'axe de charnière X-X à un second angle limite α2, et ceci dans un sens de rotation éloignant les deux surfaces supérieures 46, 76 l'une de l'autre. Le second angle limite est par exemple inférieur à 3°.The buffer assembly 6 furthermore comprises second stop means 122 adapted to limit the breaking angle of the second buffer 42 with respect to the first buffer 40 around the hinge axis XX at a second limiting angle α 2, and this in a direction of rotation away from the two upper surfaces 46, 76 of one another. The second limiting angle is for example less than 3 °.

Les seconds moyens de butée 122 comprennent un premier nez 124 disposé sur la première nervure de liaison 60 du premier tampon 40 et un second nez 126 disposé sur la seconde nervure de liaison 90 du second tampon 42. Les premier 124 et second nez 126 sont disposés adjacents au bord inférieur libre de la nervure de liaison 60, 90 correspondante.The second stop means 122 comprise a first nose 124 disposed on the first connecting rib 60 of the first buffer 40 and a second nose 126 disposed on the second connecting rib 90 of the second buffer 42. The first 124 and second nose 126 are arranged adjacent to the free lower edge of the corresponding connecting rib 60, 90.

Les premiers et seconds tampons 40, 42 sont libres en rotation autour de l'axe de charnière X-X entre la configuration alignée de l'ensemble de tampons 6 et la configuration dans laquelle le second tampon 42 forme par rapport au premier tampon 40 le second angle limite α2.The first and second buffers 40, 42 are free to rotate about the hinge axis XX between the aligned configuration of the buffer assembly 6 and the configuration in which the second buffer 42 forms with respect to the first buffer 40 the second angle limit α2.

Le second angle limite α2 est par ailleurs défini par les premiers moyens de butée 112 étant donné que lorsque le second angle limite α2 est atteint, les premiers moyens de butée 112 s'opposent à la séparation des deux nervures de liaison 60, 90 au-delà du second angle limite α2.The second limiting angle α 2 is furthermore defined by the first stop means 112 since, when the second limiting angle α 2 is reached, the first abutment means 112 oppose the separation of the two connecting ribs 60, 90 from each other. beyond the second limiting angle α2.

Le dispositif de voirie 2 est en outre muni d'une première charnière 130 adaptée pour guider l'ensemble de tampons 6 autour d'un premier axe de basculement A1-A1 autour du cadre 4 entre la position fermée et la position ouverte. La première charnière 130 comporte un premier charnon de cadre 132 et un premier charnon de tampon 134.The road device 2 is further provided with a first hinge 130 adapted to guide the set of pads 6 around a first tilting axis A1-A1 around the frame 4 between the closed position and the open position. The first hinge 130 includes a first frame hinge 132 and a first hinge 134.

Le dispositif de voirie 2 est en outre muni d'une seconde charnière 136 adaptée pour guider l'ensemble de tampons 6 autour d'un second axe de basculement A2-A2 autour du cadre 4 entre la position fermée et la position ouverte. La seconde charnière 136 comporte un premier charnon de cadre 138 et un premier charnon de tampon 140.The road device 2 is further provided with a second hinge 136 adapted to guide the set of pads 6 around a second tilt axis A2-A2 around the frame 4 between the closed position and the open position. The second hinge 136 includes a first frame hinge 138 and a first hinge knuckle 140.

Le dispositif de voirie 2 des Figures 1 à 9 est une variante non-bloquée. Le dispositif de voirie 2 ne comporte donc pas de moyens de verrouillage ou de blocage s'opposant à un soulèvement de l'ensemble de tampons 6 par rapport au cadre 4 ou à un basculement de l'ensemble de tampons 6 depuis sa position fermée vers sa position ouverte.The road system 2 of the Figures 1 to 9 is an unblocked variant. The road device 2 therefore does not comprise locking or blocking means opposing lifting the buffer assembly 6 with respect to the frame 4 or tilting the set of pads 6 from its closed position to his open position.

Le dispositif de voirie fonctionne de la façon suivante.The road system operates as follows.

On part de la configuration fermée.We start from the closed configuration.

Dans cette configuration, l'ensemble de tampons 6 est disposé dans le cadre 4 et toutes les surfaces d'appui des deux tampons 40 et 42 s'appliquent sur les surfaces d'appui du cadre associées. En fonction des désalignements éventuels des divers appuis des deux tampons sur le cadre, l'angle de brisure entre les deux tampons 40, 42 est situé entre 0° (configuration alignée) et le second angle limite α2 ou entre 0° et le premier angle limite α1.In this configuration, the pad assembly 6 is disposed in the frame 4 and all bearing surfaces of the two pads 40 and 42 are applied to the associated frame support surfaces. Depending on the possible misalignments of the various supports of the two buffers on the frame, the breaking angle between the two buffers 40, 42 is between 0 ° (aligned configuration) and the second limiting angle α2 or between 0 ° and the first angle limit α1.

Lors du passage d'un véhicule, les deux tampons ne boitent donc pas par rapport au cadre, en raison d'une stabilité d'appui en trois points.When passing a vehicle, the two buffers therefore do not limp relative to the frame, because of a three point support stability.

Afin d'ouvrir le dispositif de voirie 2 par basculement de l'ensemble de tampons 6 autour du cadre, on introduit un organe de manoeuvre dans une ouverture de manoeuvre du premier tampon 40 et on soulève le premier tampon 40 par rapport au cadre et par rapport au second tampon 42 autour le l'axe de charnière X-X, jusqu'à ce que le premier tampon 40 et le second tampon 42 soient dans la configuration dans laquelle le second tampon 42 forme par rapport au premier tampon 40 le premier angle limite α1.In order to open the road device 2 by tilting the set of buffers 6 around the frame, an operating member is introduced into an operating opening of the first buffer 40 and the first buffer 40 is raised relative to the frame and by relative to the second buffer 42 about the hinge axis XX, until the first buffer 40 and the second buffer 42 are in the configuration in which the second buffer 42 forms with respect to the first buffer 40 the first limit angle α1 .

Ensuite, on poursuit le soulèvement du premier tampon 40 par rapport au cadre 4. Le premier tampon 40 et le second tampon 42 basculent alors d'un seul bloc autour de l'axe de basculement A2-A2 jusqu'à ce que l'ensemble de tampons 6 soit dans la position ouverte (voir Figure 2).Then, the first buffer 40 is continued with respect to the frame 4. The first buffer 40 and the second buffer 42 then pivot in a single block around the A2-A2 tilting axis until the assembly of pads 6 is in the open position (see Figure 2 ).

En variante, on peut aussi introduire un organe de manoeuvre dans une ouverture de manoeuvre du second tampon 42 et soulever le second tampon 42 par rapport au cadre et par rapport au premier tampon 40 autour le l'axe de charnière X-X, jusqu'à ce que le second tampon 42 et le premier tampon 40 soient dans la configuration dans laquelle le premier tampon 40 forme par rapport au second tampon 42 le premier angle limite α1.Alternatively, it is also possible to introduce an operating member into an operating opening of the second buffer 42 and to lift the second buffer 42 with respect to the frame and with respect to the first buffer 40 about the hinge axis XX, until that the second buffer 42 and the first buffer 40 are in the configuration in which the first buffer 40 forms with respect to the second buffer 42 the first limiting angle α1.

Ensuite, on poursuit le soulèvement du second tampon 42 par rapport au cadre 4. Le second tampon 42 et le premier tampon 40 basculent alors d'un seul bloc autour de l'axe de basculement A1-A1 jusqu'à ce que l'ensemble de tampons 6 soit dans la position ouverte.Then, the second buffer 42 is continued with respect to the frame 4. The second buffer 42 and the first buffer 40 then pivot in a single block about the A1-A1 tilting axis until the assembly buffer 6 is in the open position.

L'ensemble de tampons 6 peut donc être ouvert, au choix, par articulation autour de l'un ou l'autre de deux côtés opposés du cadre 4.The set of pads 6 can therefore be optionally open by hinge around one or the other of two opposite sides of the frame 4.

En variante, le dispositif de voirie 2 peut également être ouvert par deux opérateurs en utilisant deux organes de manoeuvre. A cet effet, en partant de la configuration fermée, on introduit un organe de manoeuvre dans chaque ouverture de manoeuvre du premier tampon 40 et du second tampon 42. Ensuite on soulève simultanément le premier tampon 40 suivant le premier sens normal SN1 et le second tampon 42 suivant le second sens normal SN2. Les deux tampons 40, 42 basculent l'un par rapport à l'autre jusqu'à ce que le premier angle limite α1 soit atteint. Ensuite, l'ensemble de tampons 6 peut être retiré d'un seul bloc du cadre 4 sensiblement perpendiculairement par rapport au plan de cadre P-P.Alternatively, the road device 2 can also be opened by two operators using two actuators. For this purpose, starting from the closed configuration, an operating member is introduced into each operating opening of the first buffer 40 and the second buffer 42. Then the first buffer 40 is simultaneously raised in the first normal direction SN1 and the second buffer. 42 according to the second normal sense SN2. The two buffers 40, 42 swing relative to each other until the first limit angle α1 is reached. Then, the set of pads 6 can be removed from a single block of the frame 4 substantially perpendicular to the P-P frame plane.

Sur la Figure 10 est représentée une variante du dispositif de voirie 2 selon l'invention.On the Figure 10 is shown a variant of the road device 2 according to the invention.

Le dispositif de voirie 2 comporte un mécanisme de poussée 150 adapté pour solliciter l'ensemble de tampons 6 vers la position ouverte. Le mécanisme de poussée 150 est muni d'un vérin à gaz 152 et d'un levier 154. Le levier 154 est fixé sur le second tampon 42. Le vérin à gaz 152 est articulé d'une part à une extrémité du levier 154 et d'autre part au cadre 4.The road device 2 comprises a push mechanism 150 adapted to urge the set of pads 6 to the open position. The thrust mechanism 150 is provided with a gas cylinder 152 and a lever 154. The lever 154 is fixed on the second buffer 42. The gas cylinder 152 is hinged on the one hand at one end of the lever 154 and on the other hand in box 4.

Le dispositif de voirie 2 comprend également une clavette de blocage 160 fixée au second tampon 42 et adaptée pour s'opposer à un soulèvement de l'ensemble de tampons 6, dans la position fermée, suivant une direction sensiblement perpendiculaire au plan de cadre P-P.The road device 2 also comprises a blocking key 160 fixed to the second buffer 42 and adapted to oppose an uprising of the set of pads 6, in the closed position, in a direction substantially perpendicular to the P-P frame plane.

Le dispositif de voirie 2 est en outre muni d'un verrou rotatif 162 disposé sur le premier tampon 40 et mobile en rotation entre une position de blocage dans laquelle le verrou rotatif 162 empêche l'ouverture de l'ensemble de tampons 6 par articulation autour du cadre 4, et une position de libération dans laquelle l'ensemble de tampons 6 peut être ouvert par basculement par rapport au cadre 4.The road device 2 is further provided with a rotary latch 162 disposed on the first buffer 40 and rotatable between a locking position in which the rotary latch 162 prevents the opening of the buffer assembly 6 by hinge around of the frame 4, and a release position in which the set of pads 6 can be opened by tilting relative to the frame 4.

L'invention peut comporter généralement l'une ou plusieurs des caractéristiques supplémentaires suivantes :The invention may generally include one or more of the following additional features:

Le ou chaque tampon a une forme sensiblement triangulaire.The or each pad has a substantially triangular shape.

Le tampon comporte une nervure longitudinale s'étendant du côté inférieur du tampon.The pad has a longitudinal rib extending from the bottom side of the pad.

L'ouverture traversante est disposée dans la fibre neutre de la nervure longitudinale, et de préférence à mi-hauteur de cette nervure.The through opening is disposed in the neutral fiber of the longitudinal rib, and preferably at mid-height of this rib.

Le ou chaque tampon est sans contre-dépouille.The or each buffer is without undercut.

Le tampon comporte un charnon d'articulation à un cadre.The pad has a hinge pin to a frame.

Le tampon comporte un charnon d'articulation coopérant avec le charnon d'articulation au cadre.The buffer comprises a hinge pin cooperating with the knuckle articulation to the frame.
