Description

Bras articule et potence équipée d'un tel bras.Articulated arm and stem equipped with such an arm.

La présente invention concerne des perfectionnements apportés aux bras articulés servant à supporter de façon mobile un appareil de manière telle, notamment, que ledit appareil puisse être déplacé parallèlement à une surface, en regard de celle-ci, en conservant une attitude donnée, ledit bras étant agencé sous forme d'un parallélogramme déformable incluant deux longerons parallèles articulés en rotation, à une extrémité respective, sur un support et, à leur autre extrémité respective, sur le susdit appareil, un organe amortisseur et un organe de blocage étant associés audit bras pour respectivement assister son déplacement et le bloquer dans une position requise. The present invention relates to improvements made to the articulated arms used to movably support an apparatus in such a way, in particular, that said apparatus can be moved parallel to a surface, facing it, while maintaining a given attitude, said arm being arranged in the form of a deformable parallelogram including two parallel longitudinal members articulated in rotation, at a respective end, on a support and, at their other respective end, on the above-mentioned device, a damping member and a blocking member being associated with said arm to respectively assist its movement and block it in a required position.

Dans les agencements connus de bras articulés tels que précité, l'organe amortisseur est interposé en diagonale entre le support et l'un des longerons constitutifs du bras, à la manière d'une contre-fiche ou d'un contreventement de longueur réglable. Un tel montage offre l'inconvénient que l'espace au-dessus du bras est en partie occupé par l'organe amortisseur, ce qui peut être gênant pour certaines conditions d'utilisation du bras articulé et ce qui, en tout cas, empêche de revêtir le bras d'un carénage intégral dissimulant la totalité de l'architecture mécanique dudit bras. In known arrangements of articulated arms as mentioned above, the damping member is interposed diagonally between the support and one of the longitudinal members of the arm, in the manner of a strut or bracing of adjustable length. Such an arrangement has the disadvantage that the space above the arm is partly occupied by the damping member, which can be inconvenient for certain conditions of use of the articulated arm and which, in any case, prevents cover the arm with an integral fairing concealing the entire mechanical architecture of said arm.

L'invention a essentiellement pour but de remédier à ces inconvénients et de proposer un agencement de bras articulé beaucoup plus ramassé, qui laisse dégagée la totalité de l'espace au-dessus et au-dessous du bras et qui autorise un capotage intégral du bras permettant de dissimuler au regard l'architecture mécanique constitutive du bras. The object of the invention is essentially to remedy these drawbacks and to propose a much more compact articulated arm arrangement, which leaves all of the space above and below the arm clear and which allows the arm to be completely covered. allowing to hide from view the mechanical architecture of the arm.

A ces fins, un bras articulé tel que mentionné au préambule, étant agencé conformément à l'invention, se caractérise essentiellement en ce que l'organe amortisseur est interposé entre les deux longerons parallèles dudit bras, avec des liaisons articulées respectives avec ceux-ci à ses deux extrémités. De préférence, l'organe amortisseur est un vérin à air à fuite contrôlée.  For these purposes, an articulated arm as mentioned in the preamble, being arranged in accordance with the invention, is essentially characterized in that the damping member is interposed between the two parallel beams of said arm, with respective articulated connections with these at both ends. Preferably, the damping member is an air cylinder with controlled leakage.

Avantageusement, l'organe de blocage comprend une bielle interposée entre les deux longerons parallèles du susdit bras, raccordée par des liaisons articulées respectives avec ceux-ci à ses deux extrémités, une desdites articulations étant fixe sur un des longerons et l'autre articulation étant mobile sur l'autre longeron et associée à un élément de blocage relâchable sur ledit longeron. Dans un mode de réalisation pratique simple, ladite autre articulation est solidaire d'une bague coulissante sur l'autre longeron et sur laquelle est prévu ledit élément de blocage. Dans un exemple de réalisation simple, l'élément de blocage comprend une vis de blocage munie d'une tête de grande dimension formant bouton de manoeuvre de blocage. Advantageously, the blocking member comprises a connecting rod interposed between the two parallel longitudinal members of the above-mentioned arm, connected by respective articulated connections with these at its two ends, one of said articulations being fixed on one of the longitudinal members and the other articulation being mobile on the other spar and associated with a releasable blocking element on said spar. In a simple practical embodiment, said other articulation is integral with a sliding ring on the other spar and on which said locking element is provided. In a simple embodiment, the locking element comprises a locking screw provided with a large head forming a locking operating button.

Grâce aux dispositions propres à l'invention, on réalise un bras articulé dont tous les composants sont logés entre les deux longerons parallèles articulés, de sorte que l'espace environnant, et notamment sousjacent, demeure dégagé. Les possibilités d'utilisation d'un tel bras se trouvent notamment améliorées et son champ de fonctionnement accru. Thanks to the arrangements specific to the invention, an articulated arm is produced, all the components of which are housed between the two parallel articulated beams, so that the surrounding space, and in particular the underlying space, remains clear. The possibilities of using such an arm are notably improved and its field of operation increased.

En outre, en raison de l'absence de toute pièce faisant saillie de part et d'autre des deux longerons, il est possible d'envisager d'équiper ce bras d'un carénage l'enveloppant intégralement, seul le bouton de blocage apparaissant hors de ce carénage. In addition, due to the absence of any part projecting on either side of the two longitudinal members, it is possible to envisage equipping this arm with a fairing which completely envelops it, only the locking button appearing. out of this fairing.

Il est alors possible de réaliser une potence propre à supporter de façon mobile un appareil, tel que par exemple un appareil de chauffage à infrarouges, qui comporte un mât solidaire d'une embase stabilisatrice, éventuellement munie d'organes de déplacement tels que des roulettes, lequel mât supporte un bras articulé agencé conformément à l'invention comme explicité ci-dessus. It is then possible to produce a bracket capable of movably supporting an appliance, such as for example an infrared heating appliance, which comprises a mast secured to a stabilizing base, possibly provided with displacement members such as rollers. , which mast supports an articulated arm arranged in accordance with the invention as explained above.

L'invention sera mieux comprise à la lecture de la description détaillée qui suit d'un mode de réalisation préféré donné uniquement à titre d'exemple non limitatif. The invention will be better understood on reading the following detailed description of a preferred embodiment given solely by way of non-limiting example.

Dans cette description, on se réfère au dessin annexé sur lequel
- La figure 1 est une vue schématique d'un bras articulé agencé conformément à l'invention ; et
- La figure 2 est une représentation très schématique d'une potence équipée d'un bras agencé selon la figure 1.In this description, reference is made to the appended drawing in which
- Figure 1 is a schematic view of an articulated arm arranged in accordance with the invention; and
- Figure 2 is a very schematic representation of a bracket equipped with an arm arranged according to Figure 1.

En se reportant à la figure 1 tout d'abord, il y est montré une structure de bras articulé agencé en parallélogramme déformable, désigné dans son ensemble par la référence 1. Ce bras comprend deux longerons parallèles 2, 3, articulés en rotation à leurs extrémités respectives, d'un côté, sur un support 4 et, de l'autre côté, sur un appareil 5 (en l'occurence, tels que représentés à la fig. 1, les deux longerons sont articulés sur une traverse 6 qui fait partie intégrante d'un appareil 5 ou à laquelle est solidarisé un appareil 5), de telle manière que l'appareil 5 puisse être déplacé verticalement en restant dans une attitude donnée, approximativement parallèlement à une surface donnée (non montrée). Referring first to FIG. 1, there is shown a structure of an articulated arm arranged in a deformable parallelogram, generally designated by the reference 1. This arm comprises two parallel longitudinal members 2, 3, articulated in rotation at their respective ends, on one side, on a support 4 and, on the other side, on a device 5 (in this case, as shown in Fig. 1, the two beams are articulated on a crosspiece 6 which makes integral part of an apparatus 5 or to which an apparatus 5 is secured, so that the apparatus 5 can be moved vertically while remaining in a given attitude, approximately parallel to a given surface (not shown).

Entre les deux longerons 2 et 3 est disposé un organe amortisseur 7, tel qu'un vérin à air à fuite contrôlée, qui est articulé en rotation à chacune de ses extrémités sur les longerons 2 et 3 respectivement. Between the two rails 2 and 3 is arranged a damping member 7, such as an air cylinder with controlled leakage, which is articulated in rotation at each of its ends on the rails 2 and 3 respectively.

Egalement entre les deux longerons 2 et 3 est disposé un organe de blocage 8 qui, dans l'exemple représenté, est constitué par une bielle 9 solidarisée avec articulation en rotation, à une extrémité, au longeron 2 et, à son autre extrémité, à un élément de blocage 10 prévu sur le longeron 3. L'élément de blocage 10 peut être constitué par une bague 11 montée à libre coulissement sur le longeron 3 et munie d'une vis de blocage 12 équipée d'une tête élargie formant bouton de manoeuvre 13. Also between the two beams 2 and 3 is disposed a blocking member 8 which, in the example shown, is constituted by a connecting rod 9 secured with articulation in rotation, at one end, to the beam 2 and, at its other end, to a blocking element 10 provided on the beam 3. The blocking element 10 may consist of a ring 11 mounted to slide freely on the beam 3 and provided with a blocking screw 12 fitted with an enlarged head forming a button. operation 13.

Dans l'agencement montré à la figure 1, la bielle 9 est disposée sensiblement parallèlement au vérin 7, cette bielle 9 et ce vérin 7 étant sensiblement inclinés par rapport aux longerons 2 et 3.  In the arrangement shown in FIG. 1, the connecting rod 9 is arranged substantially parallel to the jack 7, this connecting rod 9 and this jack 7 being substantially inclined relative to the side members 2 and 3.

Un bras articulé tel que décrit ci-dessus et représenté à la figure 1 est très compact et aucun composant (excepté le bouton de manoeuvre 13) ne fait saillie ni audessus du longeron 2, ni au-dessous du longeron 3, ni latéralement de part et d'autre du plan approximativement vertical défini par lesdits longerons 2, 3. Le bras peut donc balayer librement tout l'espace vertical, dans les limites imposées par la structure, sans que ce mouvement soit restreint par la présence d'un quelconque composant. En outre, il est facile, ainsi, de prévoir un capotage propre à dissimuler la structure mécanique du bras 1. An articulated arm as described above and represented in FIG. 1 is very compact and no component (except the operating button 13) protrudes either above the spar 2, nor below the spar 3, nor laterally on the side and on the other side of the approximately vertical plane defined by said beams 2, 3. The arm can therefore sweep freely all the vertical space, within the limits imposed by the structure, without this movement being restricted by the presence of any component . In addition, it is therefore easy to provide a cover suitable for concealing the mechanical structure of the arm 1.

A la figure 2 est représentée schématiquement une potence équipée d'un bras conforme à l'invention. La potence, désignée dans son ensemble par la référence 14, comporte un mât 15, éventuellement télescopique pour autoriser un réglage en hauteur, qui repose sur une embase 16 qui peut être déplaçable et munie à cet effet de roulettes 17. A sa partie supérieure, le mât 15 supporte un bras articulé 1 agencé conformément à l'invention et comme montré à la figure 1, le haut du mât 15 tenant lieu de support 4. In Figure 2 is shown schematically a bracket equipped with an arm according to the invention. The bracket, designated as a whole by the reference 14, comprises a mast 15, possibly telescopic to allow a height adjustment, which rests on a base 16 which can be movable and provided for this purpose with rollers 17. At its upper part, the mast 15 supports an articulated arm 1 arranged in accordance with the invention and as shown in FIG. 1, the top of the mast 15 serving as a support 4.

Le bras 1 est pourvu d'un capotage intégral 18 duquel seul le bouton de manoeuvre de blocage 13 émerge à travers une lumière allongée (non visible). Des soufflets déformables 19, 20 peuvent être prévus pour raccorder le capotage 18 avec le mât 15, d'une part, et pour raccorder le capotage 18 avec l'appareil 5, d'autre part, afin de dissimuler les articulations respectivement sans gêner le libre jeu de celles-ci.The arm 1 is provided with an integral cover 18 from which only the locking operating button 13 emerges through an elongated lumen (not visible). Deformable bellows 19, 20 can be provided to connect the cowling 18 with the mast 15, on the one hand, and to connect the cowling 18 with the device 5, on the other hand, in order to conceal the joints respectively without disturbing the free play of these.

Comme il va de soi et comme il résulte déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus particulièrement envisagés ; elle en embrasse au contraire toutes les variantes.  As is obvious and as already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged; on the contrary, it embraces all its variants.
