- the suspension members 124 and 126, and more particularly their hubs 1244 and 1264 thus serve to transmit a displacement force F3 of FIG. housing 1 10 to the cradle 150, along the rail 50.
- the openings 1516 and 1517 each have a length L151, parallel to the axis A151 and a width 151 perpendicular to this axis, which are greater than dimensions of the hubs 1244 and 1265 measured parallel to a longitudinal axis A1 10 of the housing 1 10 and perpendicular to this axis.
- the cradle 150 can be mounted on the housing after the installation of the suspension members 124, 126 on the housing 1 10. In the opposite case, the suspension members 124, 126 may be put in place after mounting of the cradle 150 on the housing 1 10.
- Z124, Z126, Z155, and Z156 axes are normally perpendicular to the tracks
- the members 124 and 126 can pivot, with an amplitude limited by the length L151, about the axes X124 and X126.
- this possibility of pivoting is less than 20 °, so that the Z124 and Z126 axes can be considered generally perpendicular to the tracks 51 and 52.
- the axes Z124, Z126, Z155 and Z156 are perpendicular to the axis X1 12.
- the members 124 and 126 are disposed on either side of the members 155 and 156, themselves arranged on either side of the wheel 1 12. This gives good stability to the trolley 100, including when traveling.
- the weight of the housing 1 10 and the elements it includes is constant during operation of the carriage 100 and the suspension members 124 and 126 only take this weight. This weight is known and stable.
- the dimensions of the wheel 1 12 and the members 124 and 126 are chosen so that the contact force between the friction wheel and the running surface consisting of the surfaces 56 and 57 is sufficient to avoid, or at least limit in a wide measuring, the sliding between the wheel 1 12 and the running surface.
- the weight of the curtain 10 in movement that is to say of the driven part of the curtain, which is variable according to the position of the carriage 100 along the rail 50, is taken up by the various carriages 20 of curtain support. The variation of this weight does not affect the quality of the contact force between the wheel 1 12 and the running surface.
- the weight of the first curtain pan P1 1 is exclusively taken up by the cradle 150 and the pads 155 and 156.
- the cradle moves the axis Z126 of the body suspension 126 by pressing, by means of the edge of the opening 1517 opposite the edge 1517A, against the hub 1264. This causes the member 126 to swing in the clockwise direction in FIG.
- the tilting of the member 126 about the axis X126 has the effect of bringing the axis A126 of the axis X1 12 in a direction perpendicular to the surfaces 56 and 57 and thereby increase this contact force.
- the contact force is lower, which allows a lower power consumption and greater autonomy.
- the contact force varies as a function of a resistant force which depends on the evolution of the load pulled or pushed by the carriage 100 during its displacement.
- the hubs 1244 and 1246 are circular in section and bear respectively against the front edge 1516A of the opening 1516 and against the rear edge 1517B of the opening 1517 which are rectilinear, in the direction of movement of the carriage 100, for transmit a driving or pulling force F3 which is directed forward in the example of FIGS. 6 and 7.
- This force F3 is tangent to a median axis Y50 of the rail 50.
- the transmission of the traction force towards forward or backward takes place at the interface between a circular surface of a hub and a rectilinear edge of an opening, which limits the friction perpendicular to the axes A1 10 and A151 which are normally merged and which can be slightly misaligned in the turning zones of the rail 50.
- the carriage 100 of this embodiment comprises a housing 1 in which is received a friction wheel January 12 intended to roll on a running surface 56 provided in the lower part of a rail 50.
- the wheel 1 12 is driven by a motor 1 16 and a gearbox 1 18.
- Two suspension members 124 and 126 equip the housing 1 10 and are provided with rollers 1245 and 1265 for rolling on a track 51 internal to the rail 50.
- a cradle 150 is provided for the attachment of a curtain, not shown, by means of tabs 153 and 154 pierced with openings for the passage of hooks mounted on the curtain.
- This cradle is equipped with two suspension members 155 and 156 also provided with rollers 1555 and 1556 provided for rolling on the track 51 of the rail 50.
- the carriage 1 10 is equipped with two pushers 132 and 134 whose outer surface, opposite the wheel 1 12, is rounded and convex.
- the outer surface of the pushers 132 and 134 is in cylinder section with a vertical axis in the mounted configuration of the carriage 100 on the rail 50.
- the cradle 150 is, meanwhile, equipped with two other pushers 162 and 164 complementary pushers 132 and 134 and each having a surface facing the housing 1 10 which is rounded and convex, as the outer surface of the pushers 132 and 134
- the tensile force F3 between the carriage 1 10 and the cradle 150 when the carriage 1 10 moves in the direction of the arrow F1 in FIGS. 8 and 9 is parallel to a tangent to the longitudinal axis Y50 of the rail 50.
- This makes it possible to cancel, to a large extent, a component of this force normal to the curvature of the rail 50, which is advantageous because this normal component could generate friction likely to disturb the efficiency of the transmission of effort between the parts 1 10 and 150 of the carriage 100.
- the choice of suitable materials also limits this friction.
- the invention has been shown in the first embodiment in the case where the members 155 and 156 for suspending the cradle 150 are formed by pads.
- these suspension members may comprise rollers rolling on the tracks of the rail.
- the suspension members of the housing of the first embodiment or the housing and the cradle of the second embodiment may comprise slippery pads.
- openings comparable to those 1516 and 1517 of the first embodiment may be provided on the housing 1 10, for the passage of suspension members of the cradle 150.
- the technical characteristics of the embodiments and variants envisaged above can be combined with each other.
