Abstract

The frame for lifting a disabled person's wheelchair out of a car, comprises a triangular plate (4) one apex of which is pivotally attached to a movable arm (2). A ram (17) rotates the plate causing a stop (16) at the second apex to bear onto an upright (1) forcing the arm to pivot outwards. An adjustable spring-biased hook (11) extends from a rod (9) attached to the third apex of the plate and cooperates with a projection (12) on the platform (3) which is hinged to the bottom of the arm to control movement of the platform during deployment.

Description

La présente invention concerne les dispositifs de fermeture des hayons élévateurs escamotables à l'intérieur des véhicules. The present invention relates to closing devices for retractable tail lifts inside vehicles.

fe dispositif selon 1'invention convient plus particulièrement aux hayons élévateurs situés à l'intérieur des véhicu les qui utilisent un bras inclinable télescopique, en particulier à celui décrit dans un brevet précédent N 79 28389. fe device according 1'invention is more particularly suitable for tail lifts located inside vehicles which use a telescopic tilting arm, in particular to that described in a previous patent N 79 28389.

Dans les dispositifs actuellement @onnus, l'escamotage du plateau est manuel, brevet US 4.015.725 N @2@@080 RFA, ou commandé par le plateau (brevet N 79 28380) relevé manuellement. Ces deux cas sont d'un service délicat pour les handicapés. In the currently known devices, the retraction of the plate is manual, US patent 4,015,725 N @ 2 @@ 080 RFA, or controlled by the plate (patent N 79 28380) raised manually. These two cases are a delicate service for the disabled.

D'autres dispositifs comportent un mécanisme complexe (US N 4.138.023) (US N 4.056.203), ou nécessitent une implantation et une forme de la carrosserie bien définies, (US N 3.826.386). Other devices include a complex mechanism (US N 4,138,023) (US N 4,056,203), or require a well-defined layout and body shape, (US N 3,826,386).

Tous ces derniers ont de plus un bandicap, étant constitués de deux rails de part et d'autre rle 1 'embrasure de porte ils necessitent d'être adaptés à chaque largeur de porte et hauteur d'entrée de porte, ou, du fait de l'épure de fonetionnement,nécessitent une forme déterminée du plancher et un pont te li'.ii-son entre ce dernier e-t le plateau. All these have a bandicap, being made up of two rails on either side of the doorway, they need to be adapted to each door width and door entry height, or, due to the working sketch, require a specific shape of the floor and a bridge te li'.ii-son between the latter and the plate.

Le dispositif selon l'invention permet d'éviter ces inconvénients. En effet une pièce unique pivotant autour d'un axe et entraînée mécaniquement en rotation dégage l'appui du bras 2 en même temps qu'elle releve le plateau 3, en fin de course la pièce 4 toujours sollicitée crée un serrage du platean et du bras contre leurs appuis afin d'éliminer les jeux cause de bruit pendant le transport. The device according to the invention makes it possible to avoid these drawbacks. Indeed, a single part pivoting around an axis and mechanically driven in rotation releases the support of the arm 2 at the same time as it raises the plate 3, at the end of the race the part 4 always stressed creates a tightening of the plate and the arms against their supports in order to eliminate games that cause noise during transport.

Selon u@e première variante fig 1 et 2 la pièce 4 articulée autour d'un axe solidaire du véhicule comporte une butée 16 servant l'appui au bras 2. According to u @ e first variant of FIGS. 1 and 2, the part 4 articulated around an axis integral with the vehicle comprises a stop 16 serving to support the arm 2.

La position de cette partie de bielle 4 doit être telle @ne lors de la descente de l'appareil, la trajectoire du doigt de relevage 12 solidaire du plateau échappe l'avant de celle-ci. En relevant la pièce 4 mécariquement, la butée de bras 16 dé@age ce dernior alors que l'ext@@@@té de la pièce 4 prend appui sous le doigt de releva@e @2 et reléve le plateau. En abaissant la pi@ce 4 le cycle @@- ve@se se produit. The end part located under nuepièce 12 called lifting finger is secured to the plate 3. The position of this connecting rod part 4 must be such when descending the device, the path of the lifting finger 12 secured to the plate escapes the front of it. By raising the part 4 mechanically, the arm stop 16 d @ @ age this latter while the ext @@@@ tee of the part 4 is supported under the finger of releva @ e @ 2 and raises the plate. By lowering the part @ 4 the cycle @@ - ve @ occurs.

Selon une deuxième variante fig. 3 et 4 la pièce @@- ticulée autour d'un axe solidaire du véhicule couiporte Lie butée 16 servant d'appui au bras 2 et, à son extrémité une bielle 9 articulée autour d'un axe solidaire de 4, l'extrém@ té de la bielle formant crochet. En relevant la bielle :1, le crochet prend appui sous le doigt de relevage 12 solidaire du plateau et le relève, alors que la butée 16 dégage le bras 2. According to a second variant fig. 3 and 4 the piece @@ - ticulated around an axis integral with the couiporte vehicle Lie stop 16 serving to support the arm 2 and, at its end a connecting rod 9 articulated around an axis integral with 4, the extrem @ tee of the connecting rod forming a hook. By raising the connecting rod: 1, the hook is supported under the lifting finger 12 secured to the plate and raises it, while the stop 16 releases the arm 2.

En abaissant @ le cycle inverse se produit, ouverture du bras et du plateau, la fin de courte de la pièce 4 étant réservée au dégagement du crochet de la trajectoire de la pièce 12.By lowering @ the reverse cycle occurs, opening of the arm and the plate, the short end of the piece 4 being reserved for the release of the hook from the trajectory of the piece 12.

Selon une troisième variante fig 5 et 6, la pince 4 articulée autour d'un axe solidaire du bras 2 comporte une butée 16 servant d'appui au bras 2 et à son extrémité une bielle Q articulée autour d'un axe solidaire de la pièce 4. la bielle -i qui comporte un crochet à son extrémité, repose sur une butée 10 solidaire de la pièce 4. En relevant la pièce 4 grâce à un vérin ou tout autre moyen mécanique, la course décrite par l'axe d'articulation de la bielle 9 améne le crochet de celle-ci en contact avec le doigt de relevage I2 de plateau
La pièce 4 continuait son pivotement, le crochet de la bielle o relève le plateau 3 alors que la butée 16 dégage le bras 2.According to a third variant fig 5 and 6, the clamp 4 articulated around an axis integral with the arm 2 has a stop 16 serving to support the arm 2 and at its end a connecting rod Q articulated around an axis integral with the part 4. the connecting rod -i which has a hook at its end, rests on a stop 10 integral with the part 4. By raising the part 4 by means of a jack or any other mechanical means, the stroke described by the hinge pin of the connecting rod 9 brings the hook thereof into contact with the lifting finger I2 of the plate
The part 4 continued its pivoting, the hook of the connecting rod o raises the plate 3 while the stop 16 releases the arm 2.

En abaissant la pièce 4 le cycle inverse se produit, la fin de course étant réservée au dégagement du crochet de la trajectoi re de descente du doigt de relevage I2.By lowering the part 4 the reverse cycle occurs, the end of travel being reserved for the release of the hook from the path of descent of the lifting finger I2.

Dans les trois variantes, afin de faciliter les réglages de synchronisation des courses de butées de bras et de plateau, le crochet Il sera réglable en position sur la bielle Q D'autre part, l'orientation judicieuse des lignes de force relevant la pièce 1+ permet de maintenir plaque le bras 2 contre une butée. L'effort de serrage du plateau 3 contre la butee en position route sera réalisé grace à un déplacement élastique d'une ou plusieurs pièces du dispositif, exemple fig. 7 - 8 - 9 - 10 - 11 - 12. In the three variants, in order to facilitate the synchronization adjustments of the arm and plate stop strokes, the hook It will be adjustable in position on the connecting rod Q On the other hand, the judicious orientation of the lines of force raising the part 1 + keeps the arm 2 plate against a stop. The clamping force of the plate 3 against the stop in the road position will be achieved by means of an elastic displacement of one or more parts of the device, example fig. 7 - 8 - 9 - 10 - 11 - 12.

chet double II dégagé du doigt de relevage I2 solidaire du plateau, permettant ainsi la montée et descente du plateau.The connecting rod 9 rests on the adjustable stop TO, the cross
chet double II released from the lifting finger I2 secured to the platform, thus allowing the platform to be raised and lowered.

Le début de course de relevage de la pièce 4 entraine la
bielle 9,le crochet double II venant prendre appui sur le
doigt de relevage, relevant ainsi le plateau 3 alors que la
butée I6 dégage le bras. En fin de course le plateau vient
s'appliquer contre sa butée, la pièce 4 continue à pivoter
et comprime le ressort I4 jusqu'à ce que la butée I6 vienne en contact avec l'arrière du bras 2, la course restante du
vérin étant utilisée pour plaquer le bras 2 contre le montant
fixe I servant de butée. Les bruits dQs aux jeux du mécanisme
étant ainsi éliminés.The start of the lifting stroke of part 4 causes the
connecting rod 9, the double hook II coming to bear on the
lifting finger, thus raising the plate 3 while the
stop I6 releases the arm. At the end of the race, the plate comes

and compresses the spring I4 until the stop I6 comes into contact with the rear of the arm 2, the remaining stroke of the
cylinder being used to press arm 2 against the upright
fixed I serving as a stop. The noises dQs at the games of the mechanism
thus being eliminated.

Pour la mise en oeuvre de l'appareil, le vérin sort et le cycle inverse se produit, à noter cependant qu'au départ
du cycle, afin d'éviter que le plateau ne reste relevé, la
partie arrière du crochet double II pousse le doit de relew vase I2 jusqu'à ce que le plateau 3,ayant franchi son point d'équilibre verticaL vienne prendre appui sur la partie avant
du crochet qui lo retlent et l'accompagne pendant son ouverture jusqu'à ce qu'il arrive en butée contre la pièce 5. La
La pièce en fin de course dégage le crochet II du doigt de relevage I2.For the implementation of the device, the cylinder goes out and the reverse cycle occurs, however it should be noted that at the start
cycle, in order to prevent the platform from remaining raised, the
rear part of the double hook II pushes the relew vase I2 until the plate 3, having crossed its vertical equilibrium point comes to rest on the front part
of the hook which lo retlent and accompanies it during its opening until it comes into abutment against the part 5. The
The end-of-travel part releases the hook II from the lifting finger I2.
