Fixing support for the articulation of a comm. door opening and closing
The invention relates to the technical sector of the means for controlling the opening and closing of the gates.

 It is known practice to use operators, generally in the form of electric jacks, to ensure the opening and closing of a gate or other gate.

portail. Une action sur le vérin assure le déplacement angulaire du portail portai 1 correspondant à l'ouverture ou à la fermeture. The jack, in particular its barrel, is mounted with free articulation on a part of the support element, for example the pillar where the portal is articulated. At its free end, the cylinder rod is articulated on an appropriate part of the

portal. An action on the jack ensures the angular movement of the portal portal 1 corresponding to the opening or closing.

 The invention is situated at the articulation of the cylinder barrel on the pillar or other fixed part receiving, with free articulation, the gate as such.

 It is a rule that the stroke of the jack is equal to the sum of the distances between the point of articulation of the barrel of the jack and the articulation of the gate considered according to two orthonormal benchmarks. It follows from this equation that the positioning of the point of articulation of the cylinder barrel relative to the articulation of the portal, is particularly important.

 However, the solutions used to allow the cylinder barrel to be fixed with capacity for articulation relative to a pillar, are not satisfactory.

 According to a simplified embodiment, commonly used, the support for fixing the barrel barrel is constituted by a support plate intended to be fixed on a part of the pillar. On this support plate, is fixed, in particular by welding and in a perpendicular plane, a tab pierced through and through for the free articulation mounting of the cylinder barrel. The adjustment is made in a very approximate way by cutting, on site, the tab to the desired length in order to best respect the above equation. We understand that such a solution is not rational.

niveau de l'un des trous sélectionnés, pour tenter de correspondre, au 1 dre, au mieux, aux rapports dimensionnels recherchés. Là encore, il s'agit d'un réglage qui, par construction, ne peut qu'être approximatif. In an attempt to remedy these drawbacks, it has been proposed to make the plate fixed in the pillar integral with a plate pierced with a plurality of holes. Such a solution avoids overlapping the plate but remains fairly imprecise as to the adjustment obtained. Indeed,. the cylinder seat will be articulated, at

level of one of the selected holes, to try to correspond, to the 1st, at best, to the dimensional ratios sought. Again, this is an adjustment which, by construction, can only be approximate.

 The object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.

 The problem which the invention proposes to solve is to be able to adjust, in a very precise manner, the point of articulation of the barrel of the jack in particular, according to the positioning of the articulation of the wing by

<Desc / Clms Page number 3>

 relative to the pillar, in order to scrupulously respect the functional dimensions required for the operation of the jack corresponding to an optimum angular opening of the leaf.

 To solve such a problem, it has been designed and developed a fixing support for the articulation of a jack, in particular for the control of angular opening and closing of a gate, remarkable in that it comprises : - a yoke suitable for being fixed on the part where the leaf is articulated; -.- the yoke has two parallel horizontal wings between which is mounted, with articulation capacity and guided angular pivoting, a coupling plate; the coupling plate is arranged for the articulation of one end of a part of the jack, the other of which is connected to the gate.

 In view of these provisions, after having determined very precisely the positioning of the articulation axis of the jack, by simply rotating the coupling plate relative to the yoke, it is possible to freeze this articulation point. For this purpose, the wings and the plate have, in combination, blocking arrangements in the desired angular position of the articulation of the jack.

 Another problem which the invention proposes to solve is to be able to adapt the thickness of the coupling plate as desired as a function, for example, of the dimensional and other characteristics of the gate.

<Desc / Clms Page number 4>

 For this purpose, the yoke is made of two identical independent squared elements each having a support and fixing lug on the part where the gate is articulated, and one of the horizontal wings between which is hinged the coupling plate which can be of variable thickness.

 In order to streamline manufacturing, the coupling plate is made up of several identical and superimposed elements.

 Given these provisions, it is: therefore possible to use several elements depending on the thickness required for the coupling plate.

 To resolve the problem posed of guiding the coupling plate as it is angularly pivoted corresponding to the adjustment of the point of articulation of the cylinder barrel, the coupling plate has, in its thickness, a light profiled in an arc, the center of which corresponds to the axis of articulation of said plate between the wings of the yoke, said light cooperating with a vertical axis passing through the wings of the yoke.

 The invention is set out below in more detail with the aid of the figures of the appended drawings in which: - Figure 1 is a perspective view of the fixing and articulation support according to the invention; - Figure 2 shows the use of the fixing support for the articulation of the cylinder barrel, in the case where the gate is articulated inside the pillar; the gate is shown in the closed position;

particularly advantageous for mounting, with articulation capacity, particularly for the advantageous Po-Ur of a control member of the jack type (V) for controlling the opening and closing of a leaf, in particular of a portal (P) articulated in (A) with respect to a pillar (PL), for example. Conventionally, 1c jack (V) has a barrel (VI) and a rod (V2). The rod (V2) is articulated on a part of the portal (P) by any known and appropriate means. The barrel (VI) is arranged at its free end, in particular in the form of a yoke (C), to be articulated, as will be indicated in the following description, on a part of the fixing support according to the characteristics of the invention.

 As shown in Figure 1, the support according to the invention has a fixing part (1) and (2) serving as a yoke and a coupling part (3) for mounting, with free articulation, of the barrel (VI ) of the jack (V). In an advantageous embodiment, the screed is produced in two distinct elements (1) and (2). Each element (1) and (2) has a support and fixing tab (la) and (2a) having arrangements (1al) and (2al) in the form of holes and / or openings for its attachment to a part

<Desc / Clms Page number 6>

 of the pillar (PL). Each of the legs (la) and (2a) is extended in a perpendicular plane by a profiled horizontal wing (lob) and (2b).

 Between the two wings (lob) and (2b), which constitute the yoke as such, is articulated, by means of an axis (4), the coupling part in the form of a profiled plate (3). Already, it is observed that it is possible, taking into account the realization of the yoke, in the form of two independent elements (1) and (2) to vary at will the spacing between the two wings (lob ) and (Zb) depending on the desired thickness of the coupling plate (3), as will be indicated in the following description.

mesure de son réglage angulaire. The coupling plate (3) has, in its thickness, a light profiled in an arc (3a) whose center corresponds to the axis of articulation (4). A guide pin (5) passes through said lumen (3a) and each of the wings (lob) and (2b) of the yoke. These provisions therefore facilitate the guiding of the coupling plate (3) relative to the yoke, as and

measurement of its angular adjustment.

ZD The free end of the coupling lug (3) is drilled right through (3b) for the engagement of a rotation axis (6) for the free articulation mounting of the barrel (VI) of the cylinder (V).

 Given these characteristics, it appears that the use of the fixing support according to the characteristics of the invention is particularly simple and effective.

 Indeed, after having fixed the yoke composed of the two elements (1) and (2), on the pillar (PL) by any known and appropriate means, such as bolts,

<Desc / Clms Page number 7>

 engaged in the holes or openings (1al) and (2al), it suffices to adjust the coupling lug (3) angularly to modify the positioning of the hole (3a) corresponding to the required positioning of the hinge pin (6) of the barrel (VI) of the jack, in order to respect the positioning ribs of this axis (6) relative to that (A), of the leaf, taking into account the stroke of the rod (V2) of the jack (V).

 The locking in angular position of the coupling lug (3) relative to the yoke (1b) and (2b) can be carried out by means of a pin (7) passing through the wings (1b) and (2b) and said plate (3).

 As indicated, if we consider the independence of elements (1) and (2), it is quite possible to modify the spacing between the two wings (1b) and (2b) according to the required thickness. for the coupling plate (3). In this regard and for the purpose of simplification and. rationalization, the coupling plate (3) can advantageously be constituted by several identical elements of the same thickness which it suffices to superimpose to achieve the desired thickness.

 Obviously, the wings (Ib) and (2b) of the plate (3) are suitably profiled to allow free angular pivoting of the assembly of the actuator and of the portal, relative to the pillar. Reference is made to FIGS. 2, 3, 4 and 5 which show different positioning of the coupling plate with respect to the fixing support yoke, as a function of the positioning of the portal hinge pin, in order to correctly position the articulation axis of the cylinder barrel.

 The advantages emerge clearly from the description, in particular it is emphasized and recalled: the reversibility of the entire support; - the very high adjustment precision obtained - the mechanical resistance with controlled forces which are returned to the rear; the possibility of modifying, at will, the thickness of the coupling plate; - ease and speed of installation.
