Abstract

The self levelling frame (1) for a push chair has an axle (7) around which a tube (2) pivots. The tube carries a sliding tube (5) on which a sub frame (3) is mounted. The sub frame supports the seat. The sliding tube forms the handle frame for the push chair and encloses the pivoting tube which contains a piston itself connected to a threaded tube end.

Description

1i 2791939 Dispositif de maintien à niveau des nacelles de landaus et1i 2791939 Level-keeping device for prams and

poussettesstrollers

DESCRIPTIONDESCRIPTION

La présente invention a pour objet un dispositif de maintien à niveau des nacelles des landaus et poussettes, ainsi que le maintien, à la même hauteur, par rapport au niveau du sol ou de la marche de l'escalator sur laquelle se trouve la personne animant la propulsion, de la poignée de guidage et de propulsion  The subject of the present invention is a device for maintaining the level of the nacelles of baby carriages and strollers, as well as maintaining, at the same height, relative to the ground level or the step of the escalator on which the animator is located propulsion, guide handle and propulsion

desdits landaus et poussettes.said baby carriages and strollers.

Le secteur technique de l'invention est celui des appareils, appareillages et procédés mis en oeuvre pour le transport des enfants au moyen de poussettes,  The technical sector of the invention is that of apparatus, apparatus and methods used for the transport of children by means of strollers,

landaus et autres appareils de transport.  baby carriages and other transport devices.

Le transport des enfants au moyen de landaus et poussettes, présente des inconvénients biens connus lorsqu'il s'agit de propulser l'ensemble à un niveau supérieur ou inférieur en utilisant un escalator ou escalier automatique. Lorsque le landau se trouve positionné sur l'escalator, dans le sens de la montée, les roues avant se trouvent à deux marches au dessus des roues arrières, et l'enfant allongé dans la nacelle est déséquilibré, sa tête étant plus basse que le niveau de ses pieds... De plus la poignée de guidage et de propulsion du landau, se trouve de ce fait, beaucoup plus bas que son niveau habituel, et oblige la personne qui anime l'opération, à se livrer à de dangereuses contorsions pour ramener l'ensemble "landau nacelle" à une position horizontale, telle qu'on l'obtient lorsque les roues avant et arrières du landau sont en position horizontale. il en va de même, mais en sens inverse, lorsque le landau se trouve positionné sur  The transport of children by prams and strollers has well-known drawbacks when it comes to propelling the whole to a higher or lower level using an escalator or automatic staircase. When the pram is positioned on the escalator, in the upward direction, the front wheels are two steps above the rear wheels, and the child lying in the basket is unbalanced, his head being lower than the level of his feet ... In addition, the guide and propulsion handle of the pram, is therefore much lower than its usual level, and forces the person leading the operation to engage in dangerous contortions to bring the set "carrycot nacelle" to a horizontal position, as obtained when the front and rear wheels of the pram are in a horizontal position. the same applies, but in reverse, when the pram is positioned on

l'escalator dans le sens de la descente.  the escalator in the direction of descent.

La présente invention vie à apporter une solution radicale et à éliminer le danger provoqué par cette situation. A cet effet, le dispositif (fig 1) est constitué d'un châssis (1) équipé de roues (8) et d'un ensemble tubulaire (2) sur lequel est fixée une armature (3) qui supporte la nacelle du landau. L'ensemble pivote autour d'un axe-essieu (7) et les amplitudes des mouvements sont amorties et freinées  The present invention lives to provide a radical solution and to eliminate the danger caused by this situation. To this end, the device (fig 1) consists of a frame (1) equipped with wheels (8) and a tubular assembly (2) on which is fixed a frame (3) which supports the carrycot nacelle. The assembly pivots around an axle-axis (7) and the amplitudes of the movements are damped and braked

par un frein amortisseur (6).by a damping brake (6).

A l'extérieur du tube (2) coulisse un autre tube (5) qui constitue la poignée de guidage et de propulsion du landau ou poussette. Ce tube (5) qui coulisse à l'extérieur du tube (2) vient buter sur un piston (10) (fig 4) coulissant lui aussi à I'intérieur du tube (5) (fig.4), lequel piston (10) est fixé au moyen d'un filetage (12) sur le tube (2). La bielle (4) est reliée, à une extrémité, au tube (5) par une platine (5 bis) au moyen d'un axe pivotant (5 ter) et à son autre extrémité, au  Outside the tube (2) slides another tube (5) which constitutes the guide and propulsion handle of the pram or stroller. This tube (5) which slides outside the tube (2) abuts on a piston (10) (fig 4) also sliding inside the tube (5) (fig. 4), which piston (10 ) is fixed by means of a thread (12) on the tube (2). The connecting rod (4) is connected, at one end, to the tube (5) by a plate (5 bis) by means of a pivoting pin (5 ter) and at its other end, to the

châssis (1) par une platine (13) et axe pivotant (14) (fig.4).  chassis (1) by a plate (13) and pivoting pin (14) (fig.4).

Ainsi lorsque les roues arrières du landau sont en position haute par rapport aux roues avant (fig.3) la bielle (4) pousse sur le tube (5) qui se trouve de ce fait propulsé vers l'extérieur (haut) du tube (2) A l'inverse, lorsque les roues arrières du landau sont en position basse par rapport aux roues avant (fig.2), la bielle (4) tire sur le tube (5) qui coulisse sur le tube (2)  Thus when the rear wheels of the pram are in the high position relative to the front wheels (fig. 3) the connecting rod (4) pushes on the tube (5) which is therefore propelled towards the outside (top) of the tube ( 2) Conversely, when the rear wheels of the pram are in the low position relative to the front wheels (fig.2), the connecting rod (4) pulls on the tube (5) which slides on the tube (2)

qui se trouve de ce fait propulsé vers l'intérieur (bas) du tube (2).  which is therefore propelled towards the inside (bottom) of the tube (2).

Ce dispositif permet, d'une part: De maintenir toujours à niveau l'armature (3) (fig.]) sur laquelle est fixée la nacelle du landau ou poussette, et ce, quelles que soient les position des roues 1 0 avant ou arrières, aussi bien à la montée qu'à la descente de l'escalator, et d'autre part: Maintenir l'extrémité extérieure du tube (5), qui est en fait la poignée de guidage et de propulsion du landau, toujours à la même distance du sol ou de la marche de l'escalator sue laquelle se trouve la personne qui guide et propulse le  This device makes it possible, on the one hand: To always keep the armature (3) (fig.]) On which the pram or stroller gimbal is fixed, regardless of the position of the wheels 1 0 before or rear, both when climbing and descending the escalator, and on the other hand: Hold the outer end of the tube (5), which is in fact the guide and propulsion handle of the pram, always at the same distance from the ground or the escalator step on which the person who guides and propels the
