Abstract

Low-power motorised lock for blocking a high load. The invention consists of a pendulum device with a rocker spring and mechanical stroke multiplier, making it possible to produce a lock functioning economically and capable of holding a high load under static conditions by buttressing. The bolt 1 can oscillate from the front to the rear in the body 2 by means of the links 3 under the combined action of its actuator 4 (having, if appropriate, a return device) and of the rocker spring. The links 3 are, for example, elastic, allowing the bolt 1 to be buttressed on the front at 7 on 8 and, with its rear part, on the bottom of the support 2. An example of use is the blocking of a hoist at a specific level.

Description

-Le but de ce verrou est de bloquer une partie mobile par rapport à une partie fixe sous charge importante. Une des applications prises en exemple fig. 1 est le cas du blocage précis d'un plancher de monte-charge à un niveau déterminé. -The purpose of this lock is to block a movable part relative to a fixed part under heavy load. One of the applications taken as an example fig. 1 is the case of the precise blocking of a freight elevator floor at a determined level.

Il existe déjà des appareil rendant ce service soit par basculement rotatif d'une pièces, soit par sortie d'une pièce coulissante.There are already devices providing this service either by rotary tilting of a part, or by exiting a sliding part.

L'appareil, selon l'invention, est caractérisé en ce que, rendant les services cités plus hauts, il ne demande qu'une énergie très faible tant pour son actionnement (frottement), l'actionnement de ses servitudes (contacts électriques, vanne pneumatique ou hydraulique) et son maintient en position verrouillée ou déverrouillée (période active) et ceci contrairement à ses prédécesseurs cités plus haut, qui sont pénalisés par effort à fournir pour actionner ces dispositifs de controle ou de commande.The apparatus, according to the invention, is characterized in that, rendering the services mentioned above, it requires only a very low energy both for its actuation (friction), the actuation of its easements (electrical contacts, valve pneumatic or hydraulic) and maintains it in the locked or unlocked position (active period) and this in contrast to its predecessors mentioned above, which are penalized by the effort required to actuate these control or command devices.

La réalisation de ces effets contradictoires : faible énergie disponible, forte résistance à vaincre en un point- du parcourt causée par les dispositifs de contrôle et commande précités est le but de l'invention dont les caractéristiques et le fonctionnement apparaîtront plus clairement dans la descriptions ci-dessous, conforme à la réalisation montrée fig.l.The achievement of these contradictory effects: low energy available, high resistance to be overcome at a point in the path caused by the aforementioned monitoring and control devices is the aim of the invention, the characteristics and operation of which will appear more clearly in the descriptions below. below, in accordance with the embodiment shown in fig.l.

Un sabot 1, logé dans une pièce parallépipèdique par exeple 2 est suspendu par des bielles 4 avantageusement faites à partir de ressorts à boudin à spires jointives, ou possédant au niveau de leurs axes de suspension/rotation un jeu déterminé, surtout par la ou les bielles situées à l'avant du patin 1. A shoe 1, housed in a parallelepipedal piece for example 2 is suspended by connecting rods 4 advantageously made from coil springs with contiguous turns, or having at the level of their axes of suspension / rotation a determined play, especially by the connecting rods located at the front of the shoe 1.

L'espace laissé entre le patin 1 et la parroi inférieure de 2 est suffisant pour permettre au patin, tiré par exemple par l'extro-ciamant 3, de prendre la position symétrique de celle représentée fig. 1, ce qui permet l'escamotage dans 2 du becpène de 1. On notera que, conforme à une caractéristique de l'invention, l'actuateur 4 tirant en un point choisi d'une bielle 3, on a ainsi une multiplication de sa course, ce qui dans l'exmeple choisi d'un électro-aimant pour actionneur, permet d'utiliser celui-ci dans la meilleure zone de sa courbe caractéristique.The space left between the shoe 1 and the lower wall of 2 is sufficient to allow the shoe, pulled for example by the extra-ciamant 3, to assume the symmetrical position of that shown in fig. 1, which allows retraction in 2 of the becpene of 1. It will be noted that, in accordance with a characteristic of the invention, the actuator 4 pulling at a chosen point of a connecting rod 3, there is thus a multiplication of its stroke, which in the chosen example of an electromagnet for actuator, allows it to be used in the best area of its characteristic curve.

Cette adaptation de l'effort demandé à l'électro-aimant ci-dessus en fonction de la course de 1 est facilitée par le fait que le verrouillage en position sortie est assuré, non seulement par le ressort de rappel éventuel de l'électro-aimant 3, mais surtout par le ressort-culbuteur dit tumbler 5 dont l'angle positif ou négatif (rentrée du pène 1) est judicieusement choisi pour s'adapter à la courbe force/course de ltélectro-aimant. Le tumbler 5, s'il ne donne qu'un faible effort, suffisant pour déplacer le pèze 1, permet ce qui est une caractéristique de l'invention, de commander un autre tumbler de commande ou de contrôle à forte charge d'intensité par exemple, qui bascule d'un bout à l'autre selon que le pène 1 a passé la position du tumbler 5 en position sortie ou en position rentrée. This adaptation of the force required from the above electromagnet as a function of the stroke of 1 is facilitated by the fact that the locking in the extended position is ensured, not only by the possible return spring of the electro- magnet 3, but above all by the tumbler spring said tumbler 5 whose positive or negative angle (retraction of the bolt 1) is judiciously chosen to adapt to the force / stroke curve of the electromagnet. The tumbler 5, if it gives only a small effort, sufficient to move the pèze 1, allows what is a characteristic of the invention, to order another command or control tumbler with high intensity load by example, which switches from one end to the other depending on whether the bolt 1 has passed the position of the tumbler 5 in the extended position or in the retracted position.

Quand le pène 1 est en position sortie et reçoit une charge 6 (positionnement du plancher de monte-charge à iso-niveau) le pène 1 est-verrouillé en anti-retour par son rebord 7 qui se bloque au point 8 de la pièce support 2, ceci grâce à l'élasticité ou au jeu d'axe des bielles avant 3, par contre, sous l'effort de la charge 6 les spires des bielles arrières 3 dont la tension était plus forte que celle du tumbler 5 se détendent et l'arrière du patin vient porter sur le fond de la pièce support 2 qui supporte alos l'effort de la charge 6.When the bolt 1 is in the extended position and receives a load 6 (positioning of the hoist floor at iso-level) the bolt 1 is locked in non-return by its flange 7 which is blocked at point 8 of the support piece 2, this thanks to the elasticity or to the play of axis of the front connecting rods 3, on the other hand, under the force of the load 6 the turns of the rear connecting rods 3 whose tension was greater than that of the tumbler 5 relax and the back of the skate comes to bear on the bottom of the support piece 2 which supports the load load 6.

Bien entendu, un appareil conforme à la description ci-dessus et à la fig. 1 peut être utilisé pour supporter une charge non plus verticale, mais horizontale (porte par exemple) sans sortir du cadre de l'invention. Bien entendi, l'appareil- décrit ci-dessus n'est donné qu à titre d'exemple. Of course, an apparatus conforming to the description above and to FIG. 1 can be used to support a load no longer vertical, but horizontal (door for example) without departing from the scope of the invention. Of course, the apparatus described above is given only by way of example.
