Description

TRAVERSEE DE TABLIER A NERVURES ANTI-CASSURE ANTI-CASSURE RIBBON APRON TRAVERSEE
La présente invention se rapporte à une traversée de tablier, notamment dans le domaine de l'automobile, permettant de faire passer un câble ou un toron à travers une cloison, par exemple une tôle, séparant le côté moteur de l'habitacle. Ces traversées de tablier ou TDT sont destinées à être passées par un trou formé dans la tôle de séparation et à y être bloquées par encliquetage .The present invention relates to a deck crossing, particularly in the automotive field, for passing a cable or strand through a partition, for example a sheet, separating the motor side of the passenger compartment. These deck penetrations or TDT are intended to be passed through a hole formed in the separating plate and to be locked by snapping.
Ce genre de TDT comporte en général un premier corps cylindrique notamment cylindrique circulaire, en un matériau, tel que le polyuréthane, rigide, et un deuxième corps cylindrique fixé, par exemple par collage, au premier corps cylindrique, ce deuxième corps cylindrique étant en un matériau mou ou souple, notamment également en PUR mais suivant une composition qui le rend mou ou souple. Le deuxième corps cylindrique peut également être un prolongement du premier corps auquel on vient rajouter une collerette.This type of TDT generally comprises a first cylindrical body, in particular a circular cylindrical body, made of a material, such as rigid polyurethane, and a second cylindrical body fixed, for example by gluing, to the first cylindrical body, this second cylindrical body being in one soft or flexible material, especially also in PUR but according to a composition that makes it soft or flexible. The second cylindrical body may also be an extension of the first body which is added a collar.
Dans la présente demande, on entend par mou ou souple, un matériau qui peut être déformé par la simple action des doigts d'un utilisateur de force moyenne. On entend par rigide, un matériau qui ne peut pas être déformé sensiblement par l'action uniquement des doigts d'une personne de force moyenne. Le corps cylindrique rigide comporte au moins un patte d' encliquetage ou clip, de préférence une pluralité de pattes d' encliquetage réparties uniformément sur la périphérie du premier corps cylindrique. Ces clips sont destinés à permettre le blocage de la tôle au niveau du bord du trou formé dans celle-ci et par lequel est inséré la TDT, le blocage étant réalisé entre le ou les clips et un rebord cylindrique extérieur du premier corps cylindrique.In the present application, soft or flexible means a material that can be deformed by the simple action of the fingers of a user of average strength. Rigid means a material that can not be deformed substantially by the action of only the fingers of a person of average strength. The rigid cylindrical body has at least one latching lug or clip, preferably a plurality of latching tabs uniformly distributed on the periphery of the first cylindrical body. These clips are intended to allow the blocking of the sheet at the edge of the hole formed therein and through which is inserted the TDT, the locking being formed between the one or more clips and an outer cylindrical rim of the first cylindrical body.
Le premier corps cylindrique comporte également un épaulement ou chanfrein s 'étendant sur toute sa périphérie, les clips étant disposés dans des évidements formés entre le chanfrein et le rebord extérieur. Chaque évidement comporte deux parois latérales transversalement au plan dans lequel s ' étend le rebord cylindrique et une paroi intérieure sensiblement parallèle au plan du rebord cylindrique, cette paroi intérieure étant en forme d'un barreau duquel est issue la patte d' encliquetage destinée à permettre l ' encliquetage de la tôle entre le rebord et elle-même. Le barreau assure la continuité du chanfrein sur toute la périphérie du corps cylindrique. Cependant, il est de petite épaisseur sur certaines zones (entre les parois latérales et la patte d' encliquetage) et peut par conséquent se casser facilement. En particulier, lorsque l'on insère la TDT dans le trou de la tôle dans lequel on souhaite fixer la TDT et qu'il est nécessaire d'insérer cette TDT suivant un axe qui n'est pas exactement perpendiculaire à l'axe du trou de la tôle, mais incliné par rapport à cet axe et notamment lorsqu'il est nécessaire de réaliser une sorte de basculement de la TDT, il peut arriver que la tôle, par son arête définissant le contour du trou, vienne taper le barreau à l'arrière du clip dans ses zones faibles et le casser. Or, ce barreau est également le support du clip et si ce barreau casse, la TDT, dans son ensemble, qui a déjà du être préalablement surmoulée sur le câble ou toron qu'elle est destinée à aider à traverser la tôle, devient inutilisable et doit être mise au rebut. La présente invention vise à surmonter - les inconvénients de l'art antérieur en proposant une traversée de tablier plus facile à insérer dans le trou du tablier dans lequel la TDT est destinée à être introduite, en particulier dans le cas où l'insertion de la traversée de tablier doit être effectuée suivant un axe qui n'est pas perpendiculaire au plan du trou du tablier mais, au contraire, nécessite de faire réaliser à la TDT un basculement partiel pour l'insérer et qui, également, a moins de chance d'être détériorée pendant le montage et notamment a moins de chance d'être rendue inutilisable en raison d'une casse d'un des clips permettant la fixation par encliquetage de la TDT à la tôle formant le tablier. Suivant l'invention, la traversée de tablier est telle que définie à la revendication 1.The first cylindrical body also has a shoulder or chamfer extending over its entire periphery, the clips being disposed in recesses formed between the chamfer and the outer edge. Each recess has two side walls transversely to the plane in which the cylindrical rim extends and a inner wall substantially parallel to the plane of the cylindrical rim, this inner wall being in the form of a bar which is provided with the latching lug intended to allow the snap of the sheet between the rim and itself. The bar ensures the continuity of the chamfer over the entire periphery of the cylindrical body. However, it is thin in some areas (between the side walls and the latching lug) and can therefore break easily. In particular, when the TDT is inserted into the hole of the sheet in which it is desired to fix the TDT and it is necessary to insert this TDT along an axis which is not exactly perpendicular to the axis of the hole. of the sheet, but inclined with respect to this axis and in particular when it is necessary to perform a kind of tilting of the TDT, it may happen that the sheet, by its edge defining the contour of the hole, comes to bang the bar to the back of the clip in its weak areas and break it. However, this bar is also the support of the clip and if this bar breaks, the TDT, as a whole, which has already had to be overmolded on the cable or strand it is intended to help cross the sheet, becomes unusable and must be scrapped. The present invention aims to overcome - the drawbacks of the prior art by providing an apron crossing easier to insert into the hole of the deck in which the TDT is intended to be introduced, especially in the case where the insertion of the apron crossing must be performed along an axis that is not perpendicular to the plane of the apron hole but, instead, requires TDT to perform a partial tilting to insert it and which, also, is less likely to deterioration during assembly and in particular is less likely to be rendered unusable due to a breakage of one of the clips for snap fastening of the TDT to the sheet forming the deck. According to the invention, the deck crossing is as defined in claim 1.
En prévoyant ainsi au moins une nervure, de préférence une pour chaque côté de l'évidement, on s'assure que lorsque l'on introduit la TDT dans le trou de la tôle dans laquelle on a l'intention de la disposer, dans le cas notamment où il convient d'introduire cetteBy thus providing at least one rib, preferably one for each side of the recess, it is ensured that when the TDT is introduced into the hole of the sheet in which it is intended to dispose, in the particular case where it is appropriate to introduce this
TDT en lui faisant subir un basculement en raison de l'orientation non parallèle à l'axe de la TDT du câble qui se trouve à l'intérieur, on évite que l'arête cylindrique de la tôle formant le bord du trou ne vienne casser le barreau qui supporte le clip, le barreau étant ainsi protégé de la tôle par la ou -les deux nervures, notamment au niveau de ses zones faibles, à proximité immédiate des parois latérales de l'évidement.TDT by tilting it due to the non-parallel orientation to the axis of the TDT of the cable which is inside, it is avoided that the cylindrical edge of the sheet forming the edge of the hole does break the bar which supports the clip, the bar being thus protected from the sheet by the or the two ribs, particularly at its weak areas, in the immediate vicinity of the side walls of the recess.
De préférence l'arête (5) intérieure du premier tronçon est chanfreinée.Preferably the inner edge (5) of the first section is chamfered.
Suivant un mode de réalisation, la ou chaque nervure a une face qui constitue un prolongement de la paroi latérale respective de l'évidement.According to one embodiment, the or each rib has a face which is an extension of the respective side wall of the recess.
De préférence la nervure s'étend à partir de sensiblement le milieu du barreau.Preferably the rib extends from substantially the middle of the bar.
De préférence, la nervure ou chaque nervure a une surface supérieure qui s'étend en biseau dans la direction de l'axe du TDT, notamment perpendiculairement au plan dans lequel s'étend le chanfrein.Preferably, the rib or each rib has an upper surface which extends in a bevel in the direction of the TDT axis, in particular perpendicular to the plane in which the chamfer extends.
En particulier, la surface supérieure de la ou de chaque nervure s'étend en biseau du chanfrein jusqu'à l'extrémité intérieure du corps cylindrique, c'est-à-dire le bord d'extrémité du deuxième tronçon, à l'opposé du chanfrein.In particular, the upper surface of the or each rib extends bevel of the chamfer to the inner end of the cylindrical body, that is to say the end edge of the second section, the opposite chamfer.
De préférence, la TDT comporte, du côté opposé à la nervure, un rebord de plus grande dimension transversale, notamment de plus grand diamètre extérieur que le premier tronçon, la patte d' encliquetage étant destinée à bloquer le bord du trou de la tôle contre ce rebord, la tôle étant prise en sandwich entre l'extrémité de la patte d' encliquetage et le rebord. De préférence, le corps cylindrique est prolongé à son extrémité du côté des nervures, c'est-à-dire du côté du deuxième tronçon, par un corps cylindrique auxiliaire en un matériau mou. De préférence, le corps cylindrique auxiliaire en un matériau mou comporte des nervures en prolongement de la ou de chaque nervure du corps principal, et notamment ces nervures du corps auxiliaire sont biseautées pour être en continuité avec la surface supérieure biseautée de la ou de chaque nervure du corps principal.Preferably, the TDT comprises, on the opposite side to the rib, a rim of greater transverse dimension, in particular of larger outer diameter than the first section, the locking lug being intended to lock the edge of the hole of the sheet against this rim, the sheet being sandwiched between the end of the latching lug and the rim. Preferably, the cylindrical body is extended at its end side of the ribs, that is to say on the side of the second section, by an auxiliary cylindrical body made of a soft material. Preferably, the auxiliary cylindrical body of a soft material comprises ribs extending from the or each rib of the main body, and in particular these ribs of the auxiliary body are bevelled to be in continuity with the beveled upper surface of the or each rib of the main body.
On peut insérer facilement la TDT dans le trou en assurant un guidage par la rampe formée par la surface supérieure de la ou des nervures du corps principal ou par la rampe formée par les surfaces supérieures des deux nervures qui sont disposées bout à bout du corps principal et du corps auxiliaire, pour ainsi guider la tôle jusqu'à sa position d' encliquetage dans l'interstice formée entre le rebord supérieur cylindrique du corps principal et la ou les pattes d' encliquetage . Ainsi, la ou chaque nervure a non seulement une fonction de protection du barreau de support du clip, mais également, dans le cas où il est biseauté en surface supérieure, une fonction de guidage de ïa TDT dans le trou de la tôle formant tablier. • De préférence, le corps cylindrique comporte une lèvre périphérique en un matériau mou, la lèvre périphérique étant disposée contre le rebord annulaire extérieur du corps entre le rebord et la ou les pattes d ' encliquetage . De préférence, le chanfrein est circulaire.The TDT can easily be inserted into the hole by guiding the ramp formed by the upper surface of the main body rib (s) or by the ramp formed by the upper surfaces of the two ribs which are arranged end to end of the main body. and the auxiliary body, thereby guiding the sheet to its latching position in the gap formed between the cylindrical upper rim of the main body and the one or more latching lugs. Thus, the or each rib has not only a protective function of the support bar of the clip, but also, in the case where it is beveled at the upper surface, a TDT guiding function in the hole of the plate forming plate. Preferably, the cylindrical body has a peripheral lip of soft material, the peripheral lip being disposed against the outer annular flange of the body between the flange and the one or more snap tabs. Preferably, the chamfer is circular.
Aux figures données à titre d'exemple, on décrit maintenant un mode de réalisation de l'invention en se reportant aux dessins, dans lesquels : la figure 1 est une vue en perspective d'une partie d'une traversée de tablier suivant un mode de réalisation de l'invention ; la figure 2 est une vue en perspective de dessus d'une partie de la traversée de tablier de la figure 1 ; et la figure 3 est une vue en coupe longitudinale suivant la ligne A-A de la figure 1.In the figures given by way of example, an embodiment of the invention will now be described with reference to the drawings, in which: FIG. 1 is a perspective view of a portion of an apron bushing in a embodiment of the invention; Figure 2 is a perspective view from above of a portion of the deck crossing of Figure 1; and Figure 3 is a longitudinal sectional view along the line AA of Figure 1.
A la figure 1, on peut voir une traversée de tablier suivant un mode de réalisation de l'invention. La traversée de tablier comporte une première bague 1 principale en un matériau dur, notamment en PUR, et une deuxième bague 2 auxiliaire en un matériau souple ou mou, notamment également en PUR. Les deux bagues sont sensiblement cylindrigues circulaires. En effet, à l'exception du ou des évid-ements 7 et des nervures, le reste des bagues (la plus grande partie) est cylindrique, ici cylindrique circulaire. La bague 1 principale comporte un premier tronçon 3 annulaire et un deuxième tronçon 4 annulaire concentrique de plus petit diamètre, les deux tronçons s 'étendant de ' la face latérale extérieure (à gauche à la figure 1) vers l'intérieur. Le tronçon 3 s'étend vers l'intérieur sur une distance moindre que le tronçon 4 qui s'étend jusqu'à une arête 50 intérieure qui correspond à l'extrémité intérieure de la bague 1 principale. Le tronçon 3 a une arête 5 en retrait du bord intérieur ou arête 50 intérieure du tronçon 4. Cette arête 5 est chanfreinée. Le chanfrein 30 est défini entre ces deux tronçons 3 et 4. Du côté opposé au deuxième tronçon 4, le premier tronçon 3 comporte un rebord annulaire 6, et un évidement 7 est formé dans le premier tronçon 3. En réalité, il est formé ici trois évidements de ce genre répartis de manière uniforme sur le pourtour périphérique du tronçon 3. L 'évidement 7 est délimité par deux parois 8, 9 ici parallèles et ici parallèles à l'axe longitudinal de la traversée de tablier. On pourrait cependant prévoir que ces deux surfaces 8, 9 ne soient ni parallèles entre elles ni parallèles à l'axe de la traversée de tablier. En revanche, elles sont toujours transversales au plan perpendiculaire à l'axe de la traversée de tablier. Ces deux parois 8, 9 correspondent à l'épaisseur radiale du tronçon 3. Un barreau 10 délimite l'évidement 7 en assurant la continuité de l'arête 5 sur toute l'extension périphérique du tronçon. Ce barreau 10 supporte une patte 11 d' encliquetage.In Figure 1, we can see a deck crossing according to one embodiment of the invention. The apron bushing comprises a first main ring 1 made of a hard material, especially PUR, and a second auxiliary ring 2 of a flexible or soft material, including also PUR. The two rings are substantially circular cylindrigues. In fact, with the exception of the recess or recesses 7 and the ribs, the remainder of the rings (the greater part) is cylindrical, here cylindrical circular. The main ring 1 comprises a first section 3 and a second annular section 4 concentric annular smaller diameter, the two sections extending from 'the outer side face (left in Figure 1) inwardly. The section 3 extends inward to a distance less than the section 4 which extends to an inner edge 50 which corresponds to the inner end of the main ring 1. The section 3 has an edge 5 set back from the inner edge or inner edge 50 of the section 4. This edge 5 is chamfered. The chamfer 30 is defined between these two sections 3 and 4. On the side opposite the second section 4, the first section 3 comprises an annular flange 6, and a recess 7 is formed in the first section 3. In reality, it is formed here three recesses of this kind uniformly distributed on the periphery of the section 3. The recess 7 is defined by two walls 8, 9 here parallel and here parallel to the longitudinal axis of the deck crossing. However, it could be provided that these two surfaces 8, 9 are neither parallel to each other nor parallel to the axis of the deck crossing. On the other hand, they are always transverse to the plane perpendicular to the axis of the deck crossing. These two walls 8, 9 correspond to the radial thickness of the section 3. A bar 10 delimits the recess 7 ensuring the continuity of the edge 5 over the entire peripheral extension of the section. This bar 10 supports a tab 11 of latching.
Cette patte 11 d ' encliquetage ou chaque patte d' encliquetage est destinée à presser le bord du trou formé dans la tôle du tablier dans lequel on souhaite disposer la traversée de tablier contre le rebord 6 annulaire. En utilisation, le bord du trou de la tôle est pris en sandwich entre d'un côté le bord d'attaque 21 de la patte 11 et de l'autre le rebord 6 annulaire.This latching lug 11 or each latching lug is intended to press the edge of the hole formed in the plate of the deck in which it is desired to have the deck penetration against the annular flange 6. In use, the edge of the hole of the sheet is sandwiched between one side of the leading edge 21 of the lug 11 and the other the rim 6 annular.
Des nervures 1-2 sont formées ici sensiblement en prolongement des parois 8 et 9. Chaque nervure 12 comporte, avec la paroi 8 ou 9 respective, une surface sensiblement en commun. Chaque nervure 12 a une surface 13 supérieure en biseau, ce biseau s 'étendant du chanfrein 5 jusqu'à l'extrémité 14 du deuxième tronçon de la bague principale. Chaque nervure 12 a la forme d'un muret. Le biseau est incliné du haut vers le bas, du chanfrein vers l'extrémité 14.Ribs 1-2 are formed here substantially in extension of the walls 8 and 9. Each rib 12 has, with the respective wall 8 or 9, a substantially common surface. Each rib 12 has an upper surface 13 bevel, this bevel extending from the chamfer 5 to the end 14 of the second section of the main ring. Each rib 12 has the shape of a wall. The bevel is inclined from top to bottom, from the chamfer to the end 14.
La ou chaque nervure 12 s'étend en prolongement des parois 8, 9, de l'arête 5' intérieure du tronçon 3 jusqu'à l'arête 50 intérieure du tronçon 4. La bague 2 auxiliaire en un matériau mou ou souple est fixée par sa tranche ou extrémité intérieure à l'extrémité intérieure de la bague principale. Suivant un autre mode de réalisation, la bague 2 auxiliaire peut être constituée d'un prolongement de la bague 1 en étant en le même matériau que celle-ci, et à laquelle on rajoute une collerette en un matériau mou. Cette fixation peut notamment se réaliser par collage ou tout autre moyen analogue approprié et bien connu dans le domaine. La bague 2 auxiliaire comporte également des nervures 15 qui viennent en correspondance avec les nervures 12 de la bague principale. La surface supérieure de chaque nervure 15, surface référencée 16 aux figures, est en biseau et, de préférence, en continuité avec le biseau de la surface 13 supérieure des nervures 12.The or each rib 12 extends in extension of the walls 8, 9, of the inner edge 5 ' of the section 3 to the inner edge 50 of the section 4. The auxiliary ring 2 of a soft or flexible material is fixed by its edge or inner end at the inner end of the main ring. According to another embodiment, the auxiliary ring 2 may consist of an extension of the ring 1 being made of the same material as the latter, and to which is added a collar made of a soft material. This attachment may in particular be achieved by gluing or any other similar means appropriate and well known in the field. The auxiliary ring 2 also has ribs 15 which correspond to the ribs 12 of the main ring. The upper surface of each rib 15, surface referenced 16 in the figures, is beveled and, preferably in continuity with the bevel of the upper surface 13 of the ribs 12.
On obtient ainsi un guidage particulièrement approprié de la traversée de tablier par rapport à la tranche de l'ouverture du tablier. Ceci est particulièrement utile lorsqu'il convient d'effectuer un basculement de la TDT. Cependant, cela est également utile même lorsqu'il n'y a pas de basculement à faire. En outre, les nervures assurent une protection du barreau 10 notamment au niveau de ses zones faibles s ' étendant entre la patte et les deux parois latérales, zones faibles créées en raison de la formation de 1 ' évidement 7 et de la patte d' encl-iquetage. Dans l'art antérieur, ces barreaux 10 n'étaient pas protégés par les nervures et la tranche de la tôle, lorsque l'insertion de la TDT était mal effectuée, pouvait venir casser ce barreau 10 et, par conséquent, rendre la TDT dans son ensemble inutilisable puisque l'on ne pouvait plus utiliser le clip 11 issu du barreau 10. On a également prévu entre le rebord 6 cylindrique et le ou les clips 11 une lèvre 20 en un matériau mou.This gives a particularly appropriate guidance of the deck crossing relative to the edge of the apron opening. This is particularly useful when TDT failover is required. However, this is also useful even when there is no failover to do. In addition, the ribs provide protection of the bar 10 particularly at its weak areas extending between the tab and the two side walls, weak areas created due to the formation of 1 'recess 7 and the tab cl' -iquetage. In the prior art, these bars 10 were not protected by the ribs and the wafer of the sheet, when the insertion of the TDT was poorly carried out, could come to break this bar 10 and, consequently, make the TDT in its set unusable since it could no longer use the clip 11 from the bar 10. There is also provided between the cylindrical rim 6 and the clip or clips 11 a lip 20 of a soft material.
La traversée de tablier comporte un fût 40 par lequel passe le câble ou le faisceau de câbles que l'on souhaite faire traverser -le tablier. Ce faisceau de câbles est normalement enveloppé dans un premier matériau de moulage que l'on fait ensuite passer dans le fût de la TDT.The deck crossing comprises a shaft 40 through which passes the cable or the bundle of cables that it is desired to cross -the apron. This bundle of cables is normally wrapped in a first molding material which is then passed into the drum TDT.
La patte a une surface supérieure s ' étendant du barreau jusqu'au bord d'attaque en forme de rampe allant de bas en haut du barreau vers le bord d'attaque.The tab has an upper surface extending from the bar to the ramp-shaped leading edge from bottom to top of the bar to the leading edge.
Dans ce mode de réalisation, les nervures sont réalisées sous la forme d'un muret ayant une épaisseur petite par rapport à la périphérie du chanfrein. Cependant, on pourrait également former des nervures de très grande épaisseur qui s'étendraient d'un évidemment jusqu'à 1 ' évidemment suivant. Prévoir des nervures de petites épaisseurs présentent cependant l'avantage de nécessiter moins de matière. In this embodiment, the ribs are made in the form of a wall having a small thickness relative to the periphery of the chamfer. However, one could also form ribs of very great thickness which would extend from one obviously to the next one. Provide ribs However, small thicknesses have the advantage of requiring less material.
