Description

The subject of the invention is an installation comprising at least one leaf pivoting about a vertical axis on a support, between an open position and a closed position, motorized drive means for this leaf comprising a vertical motor shaft and means leaf locking, at least in the long position, by its displacement in translation.

A portal with two motorized leaves which can be locked in the open position and in the closed position is known from patent application EP O 221 827. In this portal, the leaves are locked and unlocked by vertically moving these leaves, the vertical movement being ensured by a sotidary cam of the leaf and a fixed roller against which the leaf is applied, towards the top, by a spring. This spring is therefore powerful enough to lift the leaf and it must be compressed to engage the leaf in a base in which it is locked.

In the case where the leaves do not have a covering battue on their closing line, the installation functions correctly whatever the order in which the leaves arrive in the closing position. On the other hand, in the presence of a battered, a device for managing the relative movements of the two leaves is necessary in order to respect the essential order of opening or closing of the leaves. In addition, the vertical locking movement of the leaves tends to compact the gravel and other elements likely to be in the locking bases, which in the long run can prevent the locking function from being carried out correctly and also prevent the automatic shutdown. of the drive motor.

The object of the present invention is to ensure the locking and unlocking of a leaf without vertical displacement and of such a kind that, in the case of overlapping by a beat of the two leaves in the closed position, the order in which the leaves close either be indifferent.

The installation according to the invention is characterized in that the leaf drive means comprise, in a horizontal plane, a first guide in which the leaf moves The pivot axis of the leaf, a second guide ensuring, with the first guide , a combined movement of rotation and translation of the leaf in a horizontal plane, and a mobile motor ensuring the driving of the leaf by adherent bearing in the second guide, the two guides having, at least at one of their ends, a rectilinear part, of which at least one is parallel to the leaf, these rectilinear parts being parallel at least when the leaf is in the closed position, so as to ensure a displacement of the leaf in horizontal transLation in this position for its locking, respectively its unlocking . Thus, the movement of the leaf in a horizontal plane, according to a combined movement of rotation and translation, is ensured simply by two guides, one of which is used simultaneously for the drive of the leaf by the motor. This motor mobiLe is preferably constituted by a pinion meshing with one of the sides of the guide which is presented as a rack.

According to an embodiment The motor shaft is carried by
The leaf, The first guide is fixed and curved, except at its ends, and cooperates with the movable motor and the second guide is on the leaf and it is rectilinear and parallel to the leaf and cooperates with a fixed axis.

According to another embodiment, the drive shaft is carried by the support, while the first guide is fixed and straight and the second guide is on the leaf and it is curved except at its straight ends parallel to the leaf and it cooperates with the mobile motor.

The gate shown in Figures 1 and 2 consists of two leaves 1 and 2 carried by cement pillars 3. Each leaf is provided with two brackets 4 and 5, respectively at its upper and lower part crossed by a vertical shaft 6 rotatably mounted in the pillar 3 by means of two consoles 7 and 8. The gate further carries an auxiliary frame 9 for a tubular motor 10 mounted vertically and whose output pinion 11 meshes with a pinion 12 fixed on
The shaft 6. The leaves are locked in the closed position in a common base 13 and in the open position in two bases 14.

The brackets 7 and 8 are identical and we will therefore only describe The lower console 8 with reference to FIGS. 3 and 4. The console 8 consists of three superimposed plates 15, 16 and 17 fixed together by means of screws. The plates 15 and 16 are spaced from each other by an extra thickness 16a of the plate 16 forming a spacer. The plate 17 has a cutout 18 extending obliquely to the axis of the pillar and having a straight side and a wavy side. The plate 16 also has a cutout 19 having a toothed side 20 extending at a constant distance from the corrugated side 18a of the cutout 18. The toothed side 20 and the side 18a constitute a guide for a movable motor consisting of a pinion 21 meshing with the teeth 20 and a roller 22 pressing against the undulating side 18a of your cutout 18 and rolling on this side 18a when the pinion 21 rolls on the teeth 20. It should be noted that the roller 22 rotates in the opposite direction of the pinion 21 wedged on the shaft 6. The horizontal arm of the bracket 5 extends between the plates 15 and 16. Between its end and the pivot point of the shaft 6, the bracket 5 has a oblong slot 23 parallel to the plane of the leaf and whose axis intercepts the axis of the shaft 6. This slot 23 is crossed, with minimum clearance, by a vertical axis 24 fixed in the plates 15 and 16 and constituting the leaf pivot axis. The groove 23 and the pin 24 constitute a second guide for the leaf 1. On these two faces, the bracket 5 has housings in which balls 25 are placed by means of which the bracket 5 bears against the plates 15 and 16. The first guide 26 formed by the cutouts 18 and 19 has, respectively at each of its ends, a rectilinear part 27 and 28 directed respectively in the direction of the locking base 13 and 14.

The movement of leaf 1 will now be described at
Using FIGS. 5 to 8 which represent four successive positions of the leaf, going from the closed position to the open position. FIG. 5 represents the leaf 1 in the closed position. In this position, the end of the leaf is locked in the base 13 by the engagement of a roller 29 integral with the leaf in a groove 30 in the base 13. The pinion 21 is at
The end of the rectilinear part 27 of the guide 26.

Similarly, the axis 24 is at one of the ends of the groove 23. When, in this position, the pinion 21 is driven by the motor in the direction of the arrow F1, it rolls on the teeth 20 while moving first of all rectilinearly in the rectilinear part 27 of the guide 26 and the leaf I carries out a translational movement, backwards, which has the effect of releasing the roller 29 from the groove 30, as shown in FIG. 6. The roller 21, continuing to rotate in the direction of the arrow F1, then leaves the straight line connecting the axis 24 to the base 13, which has the effect of driving the panel 1 in rotation around the axis 24 The guide 26 not being in an arc centered on the axis 24, the roller 1 is driven simultaneously in a translational movement. The undulating shape of the guide 26 makes it possible to minimize this translational movement, it that is to say to minimize the length of the slot 23. It would however be possible to give the guide 2 6 another shape, in particular a non-wavy shape, but in this case it would be necessary to extend the slot 23. FIG. 7 shows the leaf 1 halfway between the bases 13 and 14.

When the pinion 21 arrives at point A, the start of the other straight part 28 of the guide 26, the roller 29 of the leaf 1 is located opposite the groove 31 of the base 14. Then rolling in the straight part 28, the pinion 21 drives the leaf 1 towards
The base 14 and the leaf locks in this base by its roller 29.

The passage from the locked open position to your locked closed position is carried out in the same way by rotating the pinion 21 in the opposite direction.

In the example described above, the leaf is locked in the closed position and in the open position in both cases by moving the leaf forward. It is however without other possibility to provide a locking in the other direction, in one or the other of the positions. Figures 9 to 12 schematically represent an embodiment in which the locking in one of the positions, which may for example be the open position, is effected by a movement of the leaf back. The lower (or upper) edge of the leaf 32, for example a flap, is provided with a projection 33 which comes to lock behind a stop 34. This leaf 32 has a longitudinal groove 23 'similar to the slot 23 in which is engaged a axis 24 'similar to axis 24. It carries an unrepresented motor driving a pinion 21' similar to pinion 21. This pinion 21 'moves in a fixed guide 35 approximately in the shape of an S having respectively a rectilinear part at its ends 36 and 37. The pinion 21 'is driven in one direction or the other depending on the position of the toothing on one side or the other of the guide 35. The displacement of the pinion 21' in the rectilinear part 36 of the guide 35 has the effect of driving the leaf 32 in a movement of transtation according to arrow F2, which has the effect of bringing
The projection 33 beyond the stop 34. The leaf 32 then initiates a rotational movement as shown in Figure 10. When the pinion 21 'arrives at the end of the curved part of the guide 35, the projection 33 of the leaf angularly exceeded the position of a second locking stop 38. By rolling in the second rectilinear end 37 of the guide 35, the pinion 21 'finally drives the leaf 32 in a movement of translation towards the front in the direction of the arrow # 3, which has the effect of bringing the projection 33 behind the locking stop 38. The leaf 32 is then closed and locked
Means similar to the means described above make it possible to obtain a rotation of a leaf of 180, as may be necessary for a door or a shutter. A first exemplary embodiment is shown diagrammatically in FIGS. 13 to 15. The leaf 32 is the same as in the previous embodiment. The pinion 21 'moves in a fixed guide 39 in the form of a C, the two ends 40 and 41 of which are rectilinear, aligned and directed in the direction of one another. Starting from the position shown in FIG. 13, which represents for example the closed position, the pinion 21 'first moves in the rectilinear part 40 of the guide 39 by driving the leaf 32 forward, which has the effect of clearing the projection 33 of the stop 34. The leaf 32 then initiates a rotational movement around the fixed axis 24 '(Figure 14). After performing a rotation of 180, the leaf 32 received and its projection 33 comes to lock behind a second stop 42 in the closed position.

In all cases, it is also possible to perform an inversion between the mobile means and the fixed guide means.

A first example of reversal is shown diagrammatically in FIGS. 16 to 19. The guide means are opposite with respect to the embodiment according to FIGS. 13 to 15. FIGS. 16 to 19 represent a leaf 43 provided with a projection 44 similar to the projection 33 carrying out a rotational movement of 1800 between two locked positions. This leaf 43 is provided with an axis 45 passing through a rectilinear groove 46 and aligned with the two locked positions. This groove 46 constitutes a first guide. The leaf 43 also has a C-shaped groove 47 identical to the groove 39 of the previous embodiment.

One of the sides of this groove 47 is toothed and meshes with a pinion 48 with a fixed axis driven by a motor carried by the leaf support. In the position shown in FIG. 16, the pinion 48 is at the bottom of the rectilinear part 49 of the groove 47 and the leaf 43 is locked by its projection 44 behind a first stop 50. When the pinion 48 starts to roll in the straight part 49 of the groove 47, the leaf 43 moves forward in the direction of the arrow F4, so that the projection 44 can bypass the stop 50. The leaf 43 is then translated in rotation at the like a toothed wheel, about its axis 45, by the pinion 48. After a rotation of a half-turn, the projection 44 of the leaf passes below a second stop 51, then the leaf 43 advances in the direction of the arrow F5 when the pinion 48 is in the second rectilinear part 52 of the groove 47. The projection 44 then comes to lock the van tail behind the stop 51.

As in the previous case, the rectilinear ends of the groove 47 can be opposite, as shown, or directed in the same direction, either to the right or to the left or both directed outward, according to the direction of the rectilinear movement of the leaf. that we want to obtain.

A reversal of the position of the motor and of the curved groove is also possible in the case of an opening at 900. An exemplary embodiment is shown in FIGS. 20 and 21.

FIG. 20 diagrammatically represents a leaf 53 in a first position, for example the unlocked closed position. This leaf 53 has a first short and straight groove 54 extending in the direction of the leaf, groove in which is engaged a fixed pivot axis 55 which is the pivot axis of the leaf on its support 56. The leaf has a second groove 57 comprising three characteristic sections, namely, a first straight section 57a aligned with groove 54, a second section 57b in an arc of a circle and a third section 57c straight and parallel to groove 54. Guiding 57 is carried out in the same way that Guidance 26 of
The first embodiment, that is to say that one of its sides has a toothing 20 'cooperating with the toothing of a drive pinion 58 of a motor fixed on the support 56 and a smooth side. The leaf 53 is further provided with a projection 59 cooperating with a fixed stop 60 for locking the leaf.

In the position shown in Figure 20, the leaf can move, either in the direction of the arrow
F6 in a translational movement, either in the direction of arrow F7, in a rotational movement, in the direction of rotation of the drive pinion 58. If the pinion 58 tends to drive the leaf 53 in the direction of arrow F6 , a movement in this direction is possible given the relative position, on the one hand, of the axis 55 and the pinion 58 and, on the other hand, the groove 54 and the straight segment 57a. The projection 59 is then placed in front of the stop 60 and locks the leaf. The rotation of the pinion 58 in
The other direction has the effect of bringing the leaf into the position shown in FIG. 20. By continuing to rotate in the same direction, the pinion 58 drives the guide 57 in rotation around it and the leaf 53 rotates around L '. axis 55 in the direction indicated by arrow F7.

After a rotation of 90, the projection 59 of the leaf 53 exceeds a second fixed stop 61 and abuts against a third fixed stop 62 located opposite the stop 61 but longer than the latter. When the leaf arrives in this position, the drive pinion 58 leaves the curved segment 57b of the guide 57 to enter the rectilinear segment 57c. In this rectilinear segment 57c, the pinion 58 still tends to pivot the leaf 53. This pivoting is however prevented by the stop 62, so that only the component of the movement in translation remains and the leaf moves in a rectilinear manner in the direction of arrow F8, until the pinion 58 is at the end of the straight segment 57c. This translational movement is also authorized by the groove 54 which slides on the axis 55. It can be seen that the third fixed stop 62 also contributes to locking, since in the locked position, the projection 59 is located between the stops -61 and 62. When unlocking, the pinion 58 rotating in the other direction also tends to drive the leaf immediately 53 in rotation, but the projection 59 g Smooth first on the stop 61 before the release of the leaf.

It is the same when starting from the locked position corresponding to the position of FIG. 20.

The pinion 58 tends to drive the leaf in rotation in the direction of arrow F7, but this rotation is prevented by the stop 60 against which the projection 59 first slides.

It is also possible to reverse the position of the pivot axis and the drive pinion.

An embodiment shown schematically in Figures 22 and 23.

In order to simplify the description, the parts identical or similar to those of the embodiment shown in FIGS. 20 and 21 have been designated by the same references accompanied by the sign '. There is therefore a leaf 53 'provided with a projection 59' cooperating with stops 60 ', 61' and 62 '. In the first position shown, closed or open position, there is a fourth stop 63 whose role is identical to the role of the stop 62 'in the second position shown. In this embodiment, the leaf 53' pivots around 'an axis 64 integral with the leaf and moving in a fixed groove 65 in the form of L, that is to say having a bent portion 65a whose length corresponds to the translational movement of the leaf for its locking, respecti vely unlocked llage. The second guide 66 is formed on the leaf. In its curved part, it has substantially the same shape as the guide 35 of FIG. 9. Like the corresponding guides in the other embodiments, it is its side furthest from the pivot axis 64 which is toothed . The driving pinion 58 'is integral with the support 56' as in the previous embodiment and meshes with the toothed side of the guide 66.

The two ends of the guide 66 are formed by rectilinear segments 66a and 66b, both parallel to the leaf and directed in the same direction.

The positions shown are The critical positions at the junction between the curved part of the guide 66 and each of the rectilinear segments 66a and 66b. As in the previous embodiment, when the pinion 58 'is in one of the two positions shown, the leaf tends to pivot when it should move in rectilinear translation. In both cases rotation is prevented by an auxiliary stop 63, respectively 62 '.

Starting from the position shown in FIG. 22, if the pinion 58 'rotates anti-clockwise, the leaf 53' also rotates anti-clockwise around its axis 64 while simultaneously backing slightly to get open or close, depending on the position re shown in Figure 22. If the pinion 58 'rotates in
clockwise, this means that the leaf 53 'has just completed its rotation of 90 from the position shown in Figure 23. Its projection 59' has passed below the locking stop 60 'and it has come up against The auxiliary stop 63 which prevents the leaf from turning further. The leaf 53 'can therefore only move rectilinearly in the direction of arrow F9, the projection 59' sliding on the stop 63. As for the pivot axis 64 iL moves freely in the groove 65.

When the leaf 53 'arrives in the position shown in FIG. 23, the pinion 58' rotating counterclockwise, the projection 59 'abuts against the auxiliary stop 62' passing below the locking stop 61 ' . The pinion 58 'continuing to rotate in the same direction, it drives the leaf 53' in the direction of the arrow F10, the projection 59 'sliding against the auxiliary stop 62'. The bent part 65a of the groove 65 allows the pivot axis 64 integral with the leaf to move with the leaf a distance equal to the length of the rectili- segment.

gene 66b. As in the previous case, the auxiliary stops 62 'and 63 contribute to locking.

When conditions allow, the drive pinion can be replaced by a rubber wheel driving the leaf by adhesion.

 By the means according to the invention iL is possible to ensure rotation of any angle of a leaf between two positions and that there is each time the choice between locking by moving the leaf forward or backward.

The motor can of course be placed horizontally. It suffices that the axis of the drive pinion is vertical.

In the examples described, the rotation of the leaf between two locked positions is 90 or 1800, but the invention is applicable to any angle of rotation. IT suffices that the parts of the guides concerned are parallel, respectively aligned, in the positions in which it is desired to effect a locking.
