La présente invention concerne un toit rétractable composé d'éléments rigides pouvant être rangés dans le coffre arrière d'un véhicule.The present invention relates to a retractable roof composed of rigid elements which can be stored in the rear boot of a vehicle.
Le toit rétractable permet ainsi de transformer un véhicule du type berline ou coupé en un véhicule du type cabriolet.The retractable roof thus makes it possible to transform a vehicle of the sedan or coupe type into a vehicle of the convertible type.
On a décrit dans la demande de brevet français No. 99 10 204 un toit rétractable pour véhicule comprenant trois éléments rigides, à savoir un élément avant, un élément intermédiaire et un élément arrière, ce dernier étant relié à la carrosserie par des bras pivotants.There has been described in French patent application No. 99 10 204 a retractable roof for a vehicle comprising three rigid elements, namely a front element, an intermediate element and a rear element, the latter being connected to the bodywork by pivoting arms.
Ces trois éléments du toit sont déplaçables entre une position dans laquelle ils recouvrent l'habitacle du véhicule, une deuxième position dans laquelle l'élément du toit avant est situé au-dessus de l'élément intermédiaire et une troisième position dans laquelle les éléments du toit sont rangés dans le coffre arrière du véhicule.These three elements of the roof can be moved between a position in which they cover the passenger compartment of the vehicle, a second position in which the element of the front roof is situated above the intermediate element and a third position in which the elements of the roof are stored in the rear boot of the vehicle.
Dans la réalisation décrite dans la demande de brevet ci- dessus, le déplacement de l'élément avant vers l'élément intermédiaire est assuré par une glissière qui permet de soulever l'élément avant par rapport à l'élément intermédiaire.In the embodiment described in the above patent application, the movement of the front element towards the intermediate element is ensured by a slide which makes it possible to lift the front element relative to the intermediate element.
Le coulissement de l'élément avant au-dessus de l'élément intermédiaire est assuré ensuite au moyen d'une glissière télescopique. Cette glissière télescopique comporte un élément télescopique avant solidaire de l'élément de toit avant, un élément télescopique arrière solidaire de l'élément de toit intermédiaire, ces deux éléments télescopiques étant reliés entre eux par un élément télescopique intermédiaire.The sliding of the front element above the intermediate element is then ensured by means of a telescopic slide. This telescopic slide comprises a front telescopic element secured to the front roof element, a rear telescopic element secured to the intermediate roof element, these two telescopic elements being interconnected by an intermediate telescopic element.
Le but de la présente invention est d'apporter des perfectionnements au toit rétractable précité.The object of the present invention is to provide improvements to the aforementioned retractable roof.
L'invention vise ainsi un toit rétractable pour véhicule, comprenant un élément de toit avant et un élément de toit arrière déplaçables, entre une première position dans laquelle ils recouvrent l'habitacle du véhicule, une deuxième position dans laquelle l'élément de toit avant est situé au-dessus de l'élément de toit arrière, une troisième position dans laquelle les deux éléments de toit sont rangés dans le coffre arrière du véhicule, les moyens pour déplacer les éléments de toit vers la deuxième position comprenant un mécanisme pour soulever l'élément de toit avant et une glissière télescopique pour déplacer l'élément de toit avant au-dessus de l'élément de toit arrière, la glissière télescopique comportant un élément télescopique avant solidaire de l'élément de toit avant, un élément télescopique arrière solidaire de l'élément de toit arrière, ces deux éléments télescopiques étant reliés entre eux par un élément télescopique intermédiaire.The invention thus relates to a retractable roof for a vehicle, comprising a movable front roof element and a rear roof element, between a first position in which they cover the passenger compartment of the vehicle, a second position in which the front roof element is located above the rear roof element, a third position in which the two roof elements are stored in the rear boot of the vehicle, the means for moving the roof elements to the second position comprising a mechanism for lifting the front roof element and a telescopic slide for moving the front roof element above the rear roof element, the telescopic slide comprising a front telescopic element integral with the front roof element, a rear telescopic element integral of the rear roof element, these two telescopic elements being interconnected by a telescopic element an intermediary.
Suivant l'invention, ce toit rétractable est caractérisé en ce que le mécanisme pour soulever l'élément de toit avant comprend deux leviers croisés articulés à leur point de croisement, l'une des extrémités de ces leviers étant articulée à l'élément télescopique avant, l'autre extrémité desdits leviers étant reliée à des moyens pour déplacer chacune de ces extrémités dans des sens opposés orientés dans une direction parallèle à l'élément télescopique avant.According to the invention, this retractable roof is characterized in that the mechanism for lifting the front roof element comprises two crossed levers articulated at their crossing point, one of the ends of these levers being articulated to the front telescopic element , the other end of said levers being connected to means for moving each of these ends in opposite directions oriented in a direction parallel to the front telescopic element.
Selon une version préférée de l'invention, chacune desdites extrémités des leviers comporte un écrou vissé sur une tige filetée solidaire de l'élément de toit avant et s'étendant dans une direction parallèle à l'élément télescopique avant, ladite tige filetée comportant deux portions dans lesquelles les pas de vis sont inversés, chacune d'elles portant l'un des écrous.According to a preferred version of the invention, each of said ends of the levers comprises a nut screwed onto a threaded rod integral with the front roof element and extending in a direction parallel to the front telescopic element, said threaded rod comprising two portions in which the threads are reversed, each of them carrying one of the nuts.
La rotation de cette tige filetée commandée par un moteur électrique permet de faire pivoter les leviers et donc de soulever l'élément de toit avant au-dessus de l'élément de toit arrière.The rotation of this threaded rod controlled by an electric motor makes it possible to rotate the levers and therefore to raise the front roof element above the rear roof element.
Le coulissement des glissières télescopiques qui peut être commandé par un second moteur électrique permet de déplacer l'élément de toit avant au-dessus de l'élément de toit arrière.The sliding of the telescopic slides which can be controlled by a second electric motor makes it possible to move the front roof element above the rear roof element.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

La glissière télescopique 4 comporte un élément télescopique avant 5 solidaire de l'élément de toit avant 1, un élément télescopique arrière 6 solidaire de l'élément de toit arrière 2, ces deux éléments télescopiques 5, 6 étant reliés entre eux par un élément télescopique intermédiaire 7.The telescopic slide 4 comprises a front telescopic element 5 secured to the front roof element 1, a rear telescopic element 6 secured to the rear roof element 2, these two telescopic elements 5, 6 being interconnected by a telescopic element intermediate 7.
Conformément à l'invention, le mécanisme 3 pour soulever l'élément de toit avant 1 comprend deux leviers croisés 8, 9 articulés à leur point de croisement 10. L'une des extrémités de ces leviers 8, 9 est articulée en 11, 12 à l'élément télescopique avant 5.According to the invention, the mechanism 3 for lifting the front roof element 1 comprises two crossed levers 8, 9 articulated at their crossing point 10. One of the ends of these levers 8, 9 is articulated at 11, 12 to the front telescopic element 5.
L'autre extrémité des leviers 8, 9 est reliée à des moyens pour déplacer chacune de ces extrémités dans des sens opposés orientés dans une direction parallèle à l'élément télescopique avant 5.The other end of the levers 8, 9 is connected to means for moving each of these ends in opposite directions oriented in a direction parallel to the front telescopic element 5.
Chacune des extrémités supérieures des leviers 8, 9 comporte un écrou 13, 14 vissé sur une tige filetée 15 solidaire de l'élément de toit avant 1 et s'étendant dans une direction parallèle à l'élément télescopique avant 5. Cette tige filetée 15 comporte deux portions 15a, 15b dans lesquelles les pas de vis sont inversés.Each of the upper ends of the levers 8, 9 comprises a nut 13, 14 screwed onto a threaded rod 15 integral with the front roof element 1 and extending in a direction parallel to the front telescopic element 5. This threaded rod 15 comprises two portions 15a, 15b in which the threads are reversed.
Chacune des portions 15a, 15b porte l'un des écrous 13, 14.Each of the portions 15a, 15b carries one of the nuts 13, 14.
Par ailleurs, l'élément de toit avant 1 comporte en son milieu un moteur électrique 16 relié par un flexible 17 à la tige filetée 15 pour l'entraîner en rotation.Furthermore, the front roof element 1 comprises in its middle an electric motor 16 connected by a hose 17 to the threaded rod 15 to drive it in rotation.
D'autre part, la tige filetée 15 est montée en rotation dans deux paliers 18, 19 fixés à l'élément de toit avant 1.On the other hand, the threaded rod 15 is rotatably mounted in two bearings 18, 19 fixed to the front roof element 1.
Comme montré notamment par les figues 1 et 2, l'élément télescopique avant 5 comporte une crémaillère 20 qui s'étend sur toute sa longueur sur laquelle est engrené (voir figure 5) un pignon 21 solidaire en rotation de l'extrémité avant de l'élément télescopique arrière 6.As shown in particular in FIGS. 1 and 2, the front telescopic element 5 comprises a rack 20 which extends over its entire length on which is meshed (see FIG. 5) a pinion 21 integral in rotation with the front end of the rear telescopic element 6.
Le pignon 21 est relié par un flexible 22 à un moteur électrique 23 fixé au milieu de l'élément de toit arrière 2. Comme indiqué par les figures 4, 5 et 6, l'élément télescopique avant 5 a une section transversale sensiblement en forme de L dont l'une des ailes porte la crémaillère 20. L'autre aile de l'élément 5 est engagée de façon coulissante dans une gorge longitudinale 7a de l'élément télescopique intermédiaire 7.The pinion 21 is connected by a hose 22 to an electric motor 23 fixed in the middle of the rear roof element 2. As shown in Figures 4, 5 and 6, the front telescopic element 5 has a substantially L-shaped cross section, one of the wings of which carries the rack 20. The other wing of the element 5 is engaged so sliding in a longitudinal groove 7a of the intermediate telescopic element 7.
Ce dernier est lui-même engagé de façon coulissante dans une gorge longitudinale 6a de l'élément télescopique arrière 6.The latter is itself slidably engaged in a longitudinal groove 6a of the rear telescopic element 6.
On voit également sur les figures 5 et 6 que l'élément télescopique arrière 6 a une section sensiblement en U dans laquelle sont logés les éléments télescopiques avant 5 et intermédiaire 7.It can also be seen in FIGS. 5 and 6 that the rear telescopic element 6 has a substantially U-shaped section in which the front telescopic elements 5 and intermediate 7 are housed.
L'une des ailes du U comporte sur sa face interne la gorge longitudinale 6a recevant de façon coulissante l'élément télescopique intermédiaire 7.One of the wings of the U has on its internal face the longitudinal groove 6a slidingly receiving the intermediate telescopic element 7.
L'autre aile du U comporte un palier 24 dans lequel est engagé l'axe du pignon 21 engrené avec la crémaillère 20.The other wing of the U has a bearing 24 in which is engaged the axis of the pinion 21 meshed with the rack 20.
En outre, le coulissement relatif des éléments télescopiques 5, 6, 7 est assuré par des billes 30.In addition, the relative sliding of the telescopic elements 5, 6, 7 is ensured by balls 30.
Par ailleurs, la section en U de l'élément télescopique arrière 6 est fermée à sa partie supérieure par deux bandes d'étanchéité souples et jointives 25, 26.Furthermore, the U-shaped section of the rear telescopic element 6 is closed at its upper part by two flexible and contiguous sealing strips 25, 26.
On voit également sur les figures 5 et 6, que la section en U de l'élément 6 comporte un espace libre 27 dans lequel s'étend un câble 28 portant les fils d'alimentation électrique du moteur électrique 16.We also see in Figures 5 and 6, that the U-shaped section of the element 6 has a free space 27 in which extends a cable 28 carrying the electric supply wires of the electric motor 16.
L'une des extrémités du flexible 28 est enroulée sur un enrouleur 29 situé près de l'extrémité arrière de l'élément télescopique arrière 6. L'autre extrémité du câble 28 est fixée le long de l'un 8 des leviers 8, 9 du mécanisme 3 de commande du soulèvement de l'élément de toit avant 1.One end of the hose 28 is wound on a reel 29 located near the rear end of the rear telescopic element 6. The other end of the cable 28 is fixed along one of the levers 8, 9 of the mechanism 3 for controlling the lifting of the front roof element 1.
On va maintenant expliquer le fonctionnement du toit rétractable que l'on vient de décrire.We will now explain the operation of the retractable roof that has just been described.
Après mise en route du moteur 16 ce dernier entraîne en rotation la tige filetée 15. Celle-ci se visse dans les écrous 13 et 14.After starting the motor 16, the latter rotates the threaded rod 15. The latter is screwed into the nuts 13 and 14.
Ces deniers entraînent les leviers 8, 9 en rapprochant leurs extrémités supérieures. Le déplacement des leviers 8, 9 commande le soulèvement de l'élément de toit avant 1, comme montré par la figure 2.These deniers drive the levers 8, 9 by bringing their upper ends together. The movement of the levers 8, 9 controls the lifting of the front roof element 1, as shown in FIG. 2.
On commande ensuite la mise en route du moteur 23.The engine 23 is then started up.
Ce dernier entraîne en rotation le pignon 21.The latter drives the pinion 21 in rotation.
La rotation du pignon 21 commande la translation de la crémaillère 20 et le coulissement de l'élément télescopique avant 5 et de l'élément télescopique intermédiaire 7 vers l'élément télescopique arrière 6.The rotation of the pinion 21 controls the translation of the rack 20 and the sliding of the front telescopic element 5 and of the intermediate telescopic element 7 towards the rear telescopic element 6.
Pendant ce mouvement, le câble 28 suit le déplacement de l'élément télescopique avant 5 et s'enroule sur l'enrouleur 29. En fin de course, l'élément de toit avant 1 est situé au-dessus de l'élément de toit arrière 2, comme montré par la figure 3.During this movement, the cable 28 follows the movement of the front telescopic element 5 and is wound on the reel 29. At the end of the travel, the front roof element 1 is located above the rear roof element 2, as shown in FIG. 3.
A partir de la position représentée sur la figure 3, les deux éléments superposés peuvent être déplacés dans le coffre arrière du véhicule par un système de bras pivotants ou par un système de glissières ou par une combinaison de ces deux systèmes. From the position shown in FIG. 3, the two superimposed elements can be moved in the rear boot of the vehicle by a system of pivoting arms or by a system of slides or by a combination of these two systems.
