Abstract

Support which may be orientated in all angular positions and heights and which may be folded and unfolded rapidly in order to facilitate all transport possibilities. Support of the pantograph type calibrated so as to exert at its extremity a force higher than the maximum load intended to be fixed thereto. The hinge is provided with a self-adjustable brake intended to be opposed to the lifting of the assembly, said arrangement differentiating the disclosed support from all existing supports where it is required to lift and block the object to be supported.

The two parts of the arm are articulated by a connecting flange on the plastic axle (5). This articulation comprises an adjustable braking (screw (9) and spring (in). The end of the upper part of the arm (4) is equipped with an articulation (6) identical to that described previously and with a fixing plate (7) designed to receive the reflector panel (8) The whole of the articulated arm is connected to the base, support (I) by means of an orientable and indexable flange (2), serving on the fold of the assembly.

Système d'équilibrage (Fig. 4) * Celui-ci est réalisé à partir d'un ressort taré (II), fixé sur le tube (3) par un axe (I2) et d'un cable (I3) guidé par les poulies (I4) et (I5), fixé à une extrémité sur le palier (16) par un axe (I7) et de l'autre, relié au bras (4) par l'axe (18).  Balancing system (Fig. 4) * This is made from a calibrated spring (II), fixed to the tube (3) by an axis (I2) and a cable (I3) guided by the pulleys (I4) and (I5), fixed at one end to the bearing (16) by an axis (I7) and on the other, connected to the arm (4) by the axis (18).

Panneau réflecteur (8) :A surface plane ou curviligne, mate ou brillante,. grannitée ou lisse, en matériaux rigides (selon l'applica.  Reflective panel (8): With a flat or curvilinear surface, matt or glossy. grannitée or smooth, in rigid materials (according to the applica.

tion du réflecteur) équipé sur sa face arrière, d'un système de fixation rapide (Fig. 2 et 3). Selon une forme de réalisation préférentielle, le panneau (8) possède deux cornières ou T aluminium (I9) noyés et collés dans celui-ci. Les cornières sont équipées de deux guides (20) selon l'une des variantes (Fig. 2 ou 4), permettent l'encrage du panneau (8) sur la platine (7) soit par vis (2I) Fig. 2, soit par le cliquet (22) sur les doigts d'accrochage (23), La face arrière du panneau (8) et de l'ensemble pied-bras (I).(3).(4) pourront être peints en noir pour servir de coupe flux.tion of the reflector) fitted on its rear side with a quick fixing system (Fig. 2 and 3). According to a preferred embodiment, the panel (8) has two angles or aluminum T (I9) embedded and glued therein. The angles are equipped with two guides (20) according to one of the variants (Fig. 2 or 4), allow the panel (8) to be anchored on the plate (7) either by screws (2I) Fig. 2, either by the pawl (22) on the attachment fingers (23), The rear face of the panel (8) and of the foot-arm assembly (I). (3). (4) can be painted in black to serve as a flow breaker.

Selon une variante (Fig. 5), le panneau de conception identique au panneau (8) décrit précedemment, peut-Etre équipé de charnière (24) sur laquelle vient s'articuler un second panneau (25) de memes dimensions. According to a variant (Fig. 5), the panel of identical design to the panel (8) described above, may be fitted with a hinge (24) on which a second panel (25) of the same dimensions is articulated.

Selon une autre variante (Fig. 6), le panneau de conception identique au panne?u (8) décrit précedemment, peut être équipé de 2 charnières (26 et 27) sur lesquelles viennent s'articuler deux 1/2 pan nesux (28 et 29) pouvsnt se renlier sur le panneau central (8). According to another variant (Fig. 6), the panel of identical design to the purlin? U (8) described previously, can be equipped with 2 hinges (26 and 27) on which two 1/2 pan nesux (28) are articulated and 29) can be tied back to the central panel (8).

D'autre part, quelque soit la variante utilisée (Fig. 5 ou 6) décrite précédemment, l'articulation (6) en bout du bras articulés (4) comporte un tourillon indexable (30) permettant de faire pivoter l'ensemble des panneaux sur 3600 et de l'immobiliser dans n'importe quelle position par la vis de blocage (31). On the other hand, whatever the variant used (Fig. 5 or 6) described above, the articulation (6) at the end of the articulated arm (4) comprises an indexable pin (30) making it possible to pivot the assembly of the panels on 3600 and immobilize it in any position by the locking screw (31).
