Description

t

  Device for suspending and guiding a mobile leaf.

  TECHNICAL FIELD OF THE INVENTION The invention is in the field of devices for maneuvering a leaf. It relates to a device for suspending and guiding a mobile leaf.

  State of the art It is recalled that it is common to suspend from a frame a leaf movable in translation, by means of rollers which circulate along a suspension rail fixed on this frame In the usual way, the rollers are mounted near the lateral ends of the upper edge of the leaf, for stable guidance of the latter during its translational movement. It appears however that such an arrangement implies a length of the suspension rail substantially equivalent to twice the width of the leaf, with the result of an overall size of the device which is excessive with regard to the single dimension of the leaf Moreover, such an arrangement makes the installation of motorized means difficult to maneuver the leaf, otherwise to further increase the overall size of the device.

  OBJECT OF THE INVENTION The object of the present invention is to propose a device for suspending and guiding a mobile leaf, whose footprint is as small as possible, both laterally and in the area overlooking the space traveled. by the leaf.

  The inventive step of the present invention consisted in its entirety, in contrast to the habits taken in the field, to dissociate the functions of suspension and guiding of the leaf, by assigning them to respective means, for: first place limit the robustness and therefore the size of the guiding means of the leaf, in relation to the weakness of the forces they are made to bear It will be understood, thanks to the suspension of the leaf by separate means supporting its weight which constitutes the majority of the loads to which the device is subjected, that the forces supported by the guide members reside only in those induced by the inertia of the leaf, especially during acceleration and deceleration to which it is subjected during its displacement ; secondly equip the leaf of a single suspension member occupying substantially the space 10 above its central zone, so as to bring the leaf along its axis of gravity in its general plane, with the advantage of not giving the rail suspension that a useful length of the order of the width of a leaf.

  From this approach, the space saving of the suspension rail overhanging the space traveled by the leaf is used to receive motorized means of maneuvering the latter.

  The device of the invention comprises means for suspending a mobile leaf along a suspension rail. It will be understood at this stage of the description that the translation of the leaf is capable of being a translation both along a rectilinear path. This suspension rail is arranged to be fixed to a load-bearing frame, being disposed overhanging the leaf. The device further comprises means for guiding the leaf along the suspension rail.

  At least one suspension roller is mounted rolling along the suspension rail, this roller carrying the leaf in its general plane.

  According to a general characteristic of the invention, the suspension means and the means for guiding the device are distinct means. The suspension roller is transversely fixed to the top of the leaf in its median zone, along its axis of gravity in its general plane. , while a guide member is fixed to the leaf at at least a remote point, to circulate along a specific guide rail arranged to be fixed to the frame parallel to the suspension rail.

  According to a first embodiment of the guiding member, it consists of a slider, indifferently continuous or discontinuous, which circulates inside a slideway formed in the guide rail It will be noted that this slider is preferably composed of two remote sections, which are respectively disposed in the vicinity of the lateral ends of the upper edge of the leaf.

  According to a second variant embodiment of the guide member, it consists of a train of remote rolling members, which are respectively arranged in the vicinity of the lateral ends of the upper edge of the leaf, these rolling bodies circulating along the rail guidance.

  It should be noted that, according to various variants, these rolling members are for example conical rollers, or else each consist of a set of rollers whose axes of rotation are concurrent, particularly orthogonal, which circulate along a respective wing of the guide rail.

  According to a preferred embodiment of the suspension means, the suspension rolling member comprises at least one pair of suspension rollers, and rotatably mounted on the body of a carriage carrying the leaf. The rollers of the pair are arranged on each side. other than the body of the carriage, so as to be arranged on either side of the general plane of the leaf, these rollers respectively flowing along flaps of a U-shaped section with flanged edges constituting the suspension rail These flaps 20 form support wings of the rollers against the suspension rail, against the weight of the leaf.

  The suspension rollers are preferably conical rollers with a slope of the order of 10. The support wings of the suspension rail are inclined corresponding to the general median plane of the leaf, for spontaneous centering of the leaf by relative to the suspension rail It will be noted that these arrangements make it possible to limit the wear of the members in contact, resulting from the support they take against each other. It will also be noted that intermediate wear parts are preferably interposed between the suspension rollers and the support flanges, on which these wear parts are particularly reported.

  According to another aspect of the invention, in particular, the body of the carriage comprises a pair of elements articulated to each other in a ball joint A first element carries the suspension rollers while a second element carries the leaf , in particular by means of a suspension hanger which it comprises at its upper edge. The guiding members are in turn connected to the leaf by means of means for adjusting their position relative to the suspension rail. These provisions constitute means of spontaneous adjustment of the orientation of the general plane of the leaf with respect to the orientation of the suspension rail and with respect to its natural orientation, that is to say according to the gravity. naturally the overall plan of the leaf rigorously parallel to, or even confused with, the general plane of its displacement in translation along the suspension rail.

  It also follows that the assembly between the leaf and the suspension and guiding device, is able to effectively withstand forces and shocks, especially 10 applied against the leaf transversely to its general plane.

  The leaf is advantageously operable "back and forth" through at least one motor member carried in any respective end of the rail This drive member is associated with a belt engaged on the carriage and on the chassis. will understand that where appropriate the inner dimensions of the suspension rail are sufficient to accommodate the motor member which flows together with the carriage.

  These arrangements are such that the massive assembly formed by the carriage and the actuator circulating while being housed inside the suspension rail, favors the prohibition of an escapement from the leaf beyond the suspension rail. .

  According to a preferred embodiment of the motorized operating means of the leaf, the motor member is a single gear motor supported on any end of the rail This motor is associated with a belt circulating around an end pulley disposed at the end. opposite the suspension rail, for example being supported by the latter, or even directly by the frame.

  It will be noted that according to a similar variant, although less advantageous because of its bulk compared with the preceding provisions, the motor unit is fixedly supported by the chassis, either above or laterally to the suspension rail, in particular by the intermediate of a device junction frame to the chassis. The suspension rail and the guide rail are preferably fixed to the frame by means of such a frame. This frame comprises in particular a laterally carrying beam, at its cantilever upper part of the suspension rail, and at its lower part. of the guide rail.

  This framework also advantageously comprises at its base at least one guide corridor of the motorized operating belt of the leaf.

  Preferably, the frame further comprises a front outer compartment, delimited between a side wing opposite the beam and a closing cap articulated on the lateral wing, the latter being supported by the suspension rail It will be noted that this outer compartment before is likely to be used for the passage of ducts, such as electrical, or even pneumatic or hydraulic.
