Abstract

The device has a chassis (9) and two sliding tubes (4, 5) connected to a push rod (11) by two axles (1, 3), respectively. The chassis is connected to the tubes by an axle (2). The tubes are driven into one another by the rod when wheels (10) of a person or object transport equipment are not in a same horizontal plan. A lever actuates a pin linked to it by a cable or rod, for integrating and disintegrating the tubes.

Description

DISPOSITIF PERMETTANT LE FRANCHISSEMENT PAR UN VEHICULE TERRESTREDEVICE FOR CROSSING BY A TERRESTRIAL VEHICLE

POSSEDANT AU MOINS UN ESSIEU, DE TOUT OBSTACLE OU EN MOUVEMENT N' EXCEDANT PAS UNE HAUTEUR DE TRENTE CENTIMETRES. POSSESSING AT LEAST ONE AXLE, ANY OBSTACLE OR MOVEMENT WITHOUT EXCEEDING A HEIGHT OF THIRTY CENTIMETERS.

1 La présente invention consiste en un dispositif permettant le franchissement par un véhicule terrestre possédant au moins un essieu, de tout obstacle statique ou en mouvement n'excédant pas une hauteur de trente centimètres, tels que escaliers, escaliers mécaniques, trottoirs, seuils d'accès et toutes différences de niveaux entre deux surfaces telles que des plans horizontaux. The present invention consists of a device allowing the crossing by a land vehicle having at least one axle, any static obstacle or movement not exceeding a height of thirty centimeters, such as stairs, escalators, sidewalks, thresholds access and any level differences between two surfaces such as horizontal planes.

Le secteur technique de l'invention est celui des appareils, appareillages et procédés mis en oeuvre pour le transport des personnes physiques et des objets au moyen d'un véhicule terrestre possédant au moins un essieu, lorsqu'il s'agit de mouvoir l'ensemble sur des escaliers, escaliers mécaniques, trottoirs, seuils d'accès, ou différences de plans d'un niveau n'excédant pas trente centimètres de hauteur, rendant le déplacement difficile, voire périlleux pour la personne ou l'objet transporté, ainsi que pour l'éventuel accompagnateur. The technical field of the invention is that of devices, apparatus and processes used for the transport of natural persons and objects by means of a land vehicle having at least one axle, when it comes to moving the together on stairs, escalators, sidewalks, access thresholds, or differences of plans of a height not exceeding thirty centimeters in height, making travel difficult or even dangerous for the person or object being transported, as well as for the eventual guide.

La présente invention vise à apporter une solution radicale à l'élimination des problèmes et dangers provoqués et liés à de telles situations. The present invention aims to provide a radical solution to the elimination of problems and dangers caused and related to such situations.

A cet effet, le dispositif (Fig. 1, 2 et 3) est constitué d'un châssis (9) Fig. 1, 2 et 3 équipé de roues (10) Fig. 1, 2 et 3, d'un ensemble tubulaire coulissant (4) et (5) Fig. 1, 2 et 3, relié par une biellette (11) Fig. 1, 2 et 3 au moyen d'articulations (1) et (3) Fig. 1, 2 et 3, le châssis étant relié à l'ensemble de tubes coulissants (4) et (5) au moyen d'une articulation (2) Fig. 1, 2 et 3. For this purpose, the device (FIG 1, 2 and 3) consists of a frame (9) FIG. 1, 2 and 3 equipped with wheels (10). 1, 2 and 3, a sliding tubular assembly (4) and (5). 1, 2 and 3, connected by a connecting rod (11). 1, 2 and 3 by means of articulations (1) and (3). 1, 2 and 3, the frame being connected to the set of sliding tubes (4) and (5) by means of a hinge (2). 1, 2 and 3.

Ainsi, les tubes coulissants (4) et (5) sont propulsés l'un dans l'autre par la biellette (11) lorsque les roues (10) ne sont plus sur le même plan horizontal (Fig. 1, 2 et 3). Ledit système comporte un amortisseur (7) Fig. 4 sous forme d'un ressort ou de tout autre système d'accompagnement intégré aux tubes (4) et (5) et relié à leur base (5) Fig. 4. Ce système permet le coulissement en souplesse des tubes (4) et (5) lors du franchisse- ment d'obstacles par le véhicule L'efficience du présent système peut être neutralisé sur sol horizontal au moyen d'un levier (8) Fig. 6, agissant sur un ergot (12) Fig. 7, relié au levier par un câble ou une tringle (13) Fig. 7, la manoeuvre solidarisant ou désolidarisant les tubes coulissants (4) et (5) Fig. 7. Thus, the sliding tubes (4) and (5) are propelled into one another by the rod (11) when the wheels (10) are no longer on the same horizontal plane (Fig. 1, 2 and 3). . Said system comprises a damper (7) FIG. 4 in the form of a spring or any other accompanying system integrated in the tubes (4) and (5) and connected to their base (5). 4. This system allows the smooth sliding of the tubes (4) and (5) when the obstacle is crossed by the vehicle. The efficiency of this system can be neutralized on horizontal ground by means of a lever (8) Fig. 6, acting on a lug (12). 7, connected to the lever by a cable or a rod (13). 7, the maneuver solidarisant or désolidarisant the sliding tubes (4) and (5) FIG. 7.

3o Ainsi, lorsque le véhicule rencontre un obstacle d'une hauteur ne dépassant pas trente centimètres, les roues (10) Fig. 1, 2 et 3 accompagnent la dénivellation, entraînant le châssis articulé (9) sur l'axe (2) Fig. 1, 2 et 3, ainsi que la biellette articulée (11) Fig. 1, 2 et 3 sur les axes (1) et (3) Fig. 1, 2 et 3 à mouvementer le tube (5) Fig. 1, 2 et 3) permet- tant ainsi à la main courante (6) de s'élever ou de s'abaisser d'une hauteur équivalente à celle de l'obstacle franchi (Fig. 1, 2 et 3) tout en gardant un angle constant par rapport au sol (Fig. 1, 2 et 3). 3o Thus, when the vehicle meets an obstacle of a height not exceeding thirty centimeters, the wheels (10) Fig. 1, 2 and 3 accompany the difference in level, driving the articulated frame (9) on the axis (2). 1, 2 and 3, as well as the articulated link (11). 1, 2 and 3 on the axes (1) and (3). 1, 2 and 3 to move the tube (5). 1, 2 and 3) thus allowing the handrail (6) to rise or fall from a height equivalent to that of the obstacle crossed (Fig. 1, 2 and 3) while keeping a constant angle to the ground (Fig. 1, 2 and 3).

Le dit système autorise les déplacements du véhicule terrestre dans les deux sens, avant ou arrière suivant la configuration de l'obstacle. The said system authorizes the movements of the land vehicle in both directions, front or rear depending on the configuration of the obstacle.

Ainsi, l'ascension de marches d'escalier pourra se faire par traction du véhicule. Thus, climbing steps can be done by pulling the vehicle.
