Description

Swing gate

The present invention relates to a swing gate.

Generally speaking, the present invention relates to the field of swing gates comprising, where appropriate, a motorized drive device setting in motion a screen following a pivoting movement.

The motorized drive device makes it possible to set the screen in motion, between at least a first position and at least a second position, by pivoting around a vertical axis. In the absence of a motorized drive device, or in the event of a breakdown, the swing gate can be pivoted by hand.

In this type of installation, it is known, for example from document FR-A1-2 673 219, to rest an upright of a swing gate screen on a support device which defines a vertical axis of rotation of the screen of the swing gate and which receives the weight of the swing gate. An arm equipped with internal teeth is intended to be mounted, in different positions, on a shaft projecting upwards from a flat base, in order to define an end position of the swing gate screen .

However, this installation has the disadvantage that the arm protrudes laterally from the base and can obstruct passage near the base. Installing this arm and adjusting the end position are complicated. In addition, the arm increases the cost price of the installation.

Document FR-A1-2 964 135 teaches, moreover, to produce a hinge by means of a base on which is received an ear, which can be molded and whose body is provided with a through housing intended to receive a set screw. This hinge does not make it possible to limit the pivoting of a screen of a swing gate, so that a stop must be provided for this purpose, in addition to this hinge.

On the other hand, it is known from document WO-A2-2008/053393 to install an electromechanical arm actuator above a plate equipped with a rack on which is mounted a clip forming a stop for the rotation of 'an arm of the electromechanical actuator. A blocking at the end of the stroke of a screen of a swing gate driven by the electromechanical actuator is not precise, because the kinematic chain between the arm of the electromechanical actuator and the screen of this swing gate necessarily presents a operating game. Additionally, this approach requires an electromechanical actuator mounted separately from the swing gate screen. It is therefore not suitable for an installation in which an electromechanical actuator is integrated into an upright of the swing gate screen, nor in the case where the swing gate screen is operated by hand, without using an electromechanical actuator to arm.

The present invention aims to resolve the aforementioned drawbacks and to propose a swing gate making it possible to precisely define an end position of pivoting stroke of a screen, by means of a reliable, inexpensive and compact device, without having to resort to to an electromechanical arm actuator.

To this end, the present invention aims at a swing gate comprising at least:

- a screen, the screen being mounted to pivot around an axis of rotation, the screen comprising at least one upright, the upright being aligned with the axis of rotation, and

- a support device, the support device supporting the upright, from below, with the possibility of pivoting around the axis of rotation, the support device comprising at least one base, the base comprising at least one guide bearing of the amount pivoting around the axis of rotation.

According to the invention, the base further comprises at least one circular rack, the circular rack being centered on the axis of rotation.

In addition, the support device comprises at least:

- a stop, the stop being immobilized on the base, in a predetermined angular position around the axis of rotation, by cooperation with the circular rack, and

- a stop pin, the stop pin being secured to the amount of the swing gate and being configured to come to rest against the stop, at the end of the pivoting stroke of the screen around the axis of rotation.

Thus, the base, which is located under the upright and which supports it, defines both the guide bearing of the upright in pivoting and the means for fixing the end stop of pivoting stroke of the screen.

In this way, the support device is compact and is arranged at the foot of the upright, ensuring a triple function of taking up the weight of the screen, guiding the screen in pivoting and delimiting an end position. screen stroke.

Furthermore, the stop pin ensures an end-of-stroke function without extending radially from the screen upright while the base is placed under this upright. This makes it possible to limit the bulk of the support device.

According to advantageous but not obligatory aspects of the invention, such a swing gate can incorporate one or more of the following characteristics, taken in any technically admissible combination:

We first describe, with reference to the , a closure installation 1 according to one embodiment of the invention.

Installation 1 includes a swing gate 2 and a motorized drive device 3.

The swing gate 2 is installed at an opening 7 made in a fence, in particular between two pillars 6 of the fence, of which a single pillar 6 is shown in the . The swing gate 2 makes it possible to selectively close the opening 7.

Alternatively, not shown, the opening 7 is made in a building or an enclosure.

The swing gate 2 of installation 1 is a movable barrier by pivoting in a horizontal plane.

The swing gate 2 includes at least one screen 5.

Here, the swing gate 2 comprises a single screen 5 represented in the .

As a variant, not shown, the swing gate 2 comprises two screens 5.

The screen 5 is configured to be mounted, in other words is mounted, pivoting around an axis of rotation Z, in particular in an assembled configuration of the installation 1. The axis of rotation Z is theoretically vertical, in the configuration installation assembly 1.

The motorized drive device 3 sets in motion the screen 5 of the swing gate 2, between at least a first position and at least a second position, corresponding respectively to a closed position and to an open position of the screen 5.

In this embodiment, the screen 5 is a mobile closing element, such as a leaf, a grille or any other equivalent material.

The swing gate 2, in particular the motorized drive device 3, comprises an electromechanical actuator 4.

This electromechanical actuator is, for example, of the type known from document FR-A1-3 096 069.

Alternatively, it is an electromechanical actuator of a different type.

The screen 5 comprises at least one upright 22. The upright 22 is aligned, in other words is configured to be aligned, on the axis of rotation Z, in particular in an assembled configuration of the swing gate 2. The electromechanical actuator 4, is configured to be arranged, in other words is arranged, at least partly inside the upright 22, in particular in the assembled configuration of the swing gate 2.

Thus, the electromechanical actuator 4 is said to be integrated into the upright 22.

In this way, given that the electromechanical actuator 4 is hidden in the upright 22, the electromechanical actuator 4 is protected from bad weather, in particular from rain, in addition the aesthetics and the size of the swing gate 2 are improved.

Furthermore, the electromechanical actuator 4 is configured to move the swing gate 2, in particular the upright 22 and the screen 5, relative to a fixed structure, in particular relative to the pillar 6 of the fence.

Thus, the swing gate 2, in particular the upright 22 and the screen 5, is driven in movement by the motorized drive device 3 and, more particularly, by the electromechanical actuator 4.

Advantageously, the amount 22 is hollow and, preferably, vertical.

Advantageously, the amount 22 is made using a profile.

Here and in no way limiting, the amount 22 can be made of metallic material, such as, for example, steel or aluminum, or of plastic material.

Advantageously, the amount 22 is configured to support, in other words supports, the screen 5, in particular in the assembled configuration of the swing gate 2.

Advantageously, the amount 22 is configured to be fixed, in other words is fixed, to the screen 5, in particular in the assembled configuration of the installation 1.

Here and in no way limiting, the fixing of the amount 22 to the screen 5 is implemented by welding, by screwing or by any other means of fixing.

Advantageously, the swing gate 2 comprises at least one interface plate 25a, 25b. The or each interface plate 25a, 25b is configured to be mounted, in other words is mounted, at one end 22a, 22b of the upright 22, in particular in the assembled configuration of the swing gate 2.

Thus, the or each interface plate 25a, 25b is secured to one end 22a, 22b of the upright 22.

Here, the swing gate 2 comprises a first interface plate 25a, which can also be called an upper interface plate, and a second interface plate 25b, which can also be called a lower interface plate. The first interface plate 25a is mounted at a first end 22a, which can also be called the upper end, of the upright 22. In addition, the second interface plate 25b is mounted at a second end 22b, which can also be called the lower end of the upright 22. The second end 22b of the upright 22 is opposite the first end 22a of the upright 22.

Advantageously, the or each interface plate 25a, 25b is configured to be fixed, in other words is fixed, to the upright 22, by means of fixing elements, in particular in the assembled configuration of the swing gate 2.

Here, each of the first and second interface plates 25a, 25b is fixed to the upright 22 by means of screw fixing elements, that is to say fixing screws represented by their axis lines 27, as illustrated in Figures 3 and 8, in particular four in number.

The number and type of fixing elements are not limiting and may be different. They can be, for example, two, three or more than five in number and/or be elastic snap-fastening elements.

Here, each fixing screw 27 is mounted through a passage opening 127 made in one of the first and second interface plates 25a, 25b and screwed into a screwing barrel, not shown, made in the upright 22 .

The swing gate 2 further comprises a retaining device 23 and a support device 24 for the screen 2 and, in particular, for the upright 22.

The retaining device 23 retains, in other words is configured to retain, the upright 22 from above, with the possibility of pivoting around the axis of rotation Z, in particular in the assembled configuration of the swing gate 2.

Thus, the retaining device 23 is mounted above the upright 22.

The retaining device 23 can also be called “high pivot”.

The support device 24 supports, in other words is configured to support, the upright 22 from below, with the possibility of pivoting around the axis of rotation Z, in particular in the assembled configuration of the swing gate 2.

Thus, the support device 24 takes up the weight effort of the screen 5.

The support device 24 can also be called “low pivot”.

Here, the swing gate 2 includes both the retaining devices 23 and support 24.

On the other hand, the retaining device 23 can be integrated into a swing gate 2 independently of the support device 24, that is to say independently of the characteristics of the present invention which concern the support device 24.

A swing gate 2 comprising the retaining device 23 without the support device 24, or vice versa, is therefore possible and also covered by this description.

Advantageously, at least the retaining device 23 is integral with the fixed structure, in particular with the pillar 6 of the fence, in particular at the level of an upper part of the pillar 6, in the assembled configuration of the installation 1, as illustrated in there .

Thus, the retaining device 23 makes it possible to create a connection between the swing gate 2, in particular the upright 22, and the pillar 6 of the fence.

In practice, in the mounted configuration of the installation 1, the retaining device 23 is mounted above the upright 22, in particular above its first end 22a.

The retaining device 23 comprises a plate 232 and, optionally, a cover 234.

The cover 234 covers, in other words is configured to cover, the plate 232, in particular in the assembled configuration of the swing gate 2.

Thus, the cover 324 improves the aesthetics of the retaining device 23 and protects the plate 232 against bad weather, pollution and shock.

Advantageously, the retaining device 23, more particularly the plate 232, is configured to be fixed, in other words is fixed, to the fixed structure, in particular to the pillar 6 of the fence, by means of fixing elements, in particular of screw fixing elements, such as threaded rods 236 sealed or screwed into the pillar 6, onto which nuts, not shown, are screwed.

Here, each threaded rod 236 is mounted through a passage opening 232A, 232B, 232C provided through a bottom plate 232D of the plate 232 which is pressed against the pillar 6, in particular in the assembled configuration of the installation 1. Each passage opening 232A, 232B, 232C is oblong in shape. The largest dimension of the passage openings 232A and 232B is vertical in the mounted configuration of the plate 232 on the pillar 6, while the largest dimension of the passage opening 232C is horizontal. This facilitates the positioning of the plate 232 against the pillar 6, respecting a predefined orientation, as explained below.

Advantageously, in the assembled configuration of the installation 1, the support device 24 is secured to the ground.

Thus, the support device 24 makes it possible to create a connection between the swing gate 2, in particular the upright 22, and the ground.

The support device 24 comprises a base 242 and, possibly, a cover 244. The cover 244 covers, in other words is configured to cover, the base 242, in particular in the assembled configuration of the installation 1.

Thus, the cover 244 improves the aesthetics of the support device 24 and protects the base 242 against bad weather, pollution and shocks.

In addition, the cover 244 has the function of limiting the risk of injury for the user of the installation 1, by preventing a person from getting a hand or foot trapped, particularly between the base 242 and the screen 5. and, more particularly, between a stop 264 and a stop pin 280 of the support device 24.

Here, the screen 5, in particular the upright 22, is configured to be mounted, in other words is mounted, pivoting, around the axis of rotation Z, relative to the pillar 6 of the fence.

Advantageously, the motorized drive device 3 further comprises an electronic control unit 12.

The electromechanical actuator 4 is controlled by the electronic control unit 12 of the motorized drive device 3.

Here and as illustrated in , the electronic control unit 12 of the motorized drive device 3 is offset relative to the electromechanical actuator 4, in particular outside the swing gate 2.

Here, the electronic control unit 12 is arranged inside an electrical box 79.

As a variant, not shown, the electronic control unit 12 of the motorized drive device 3 is offset relative to the electromechanical actuator 4 inside the swing gate 2 and, more particularly, inside the upright 22 .

As a variant, not shown, the electronic control unit 12 of the motorized drive device 3 is arranged inside the electromechanical actuator 4 and, more particularly, a casing of the electromechanical actuator 4.

Advantageously, the electromechanical actuator 4 is supplied with electrical energy by means of the electrical power cable 9, represented by a dotted line, only in Figures 1, 2 and 5. The electrical power cable 9 extends, in part, inside the upright 22 and passes through an opening 25b1 provided in the second interface plate 25b.

We now describe, in more detail and with reference to Figures 2 to 7, the support device 24 belonging to the closure installation 1 illustrated in and, more particularly, to the swing gate 2.

The base 242 is preferably made by metal casting. The fact that the base 242 is obtained by molding is particularly advantageous in terms of cost price, since it is then not necessary to implement rework steps by machining. This is also advantageous in terms of strength and mechanical stability. The lifespan of the support device 24 is thus improved.

The base 242 is intended to be immobilized relative to the fixed part of the installation 1, in particular relative to the ground, as explained above, and to serve as a pivot for the screen 5. It can, as such, , be described as a “crapaudine”.

Advantageously, the base 242 is in one piece.

The base 242 comprises at least one bearing 250 for guiding the upright 22 in pivoting around the axis of rotation Z, in other words a cylindrical hub of circular section, centered on a central axis A24 of the support device 24. We denote V250 a volume of the bearing 250, in particular internal, given that the bearing 250 is hollow.

Advantageously, a ring 252 is mounted around the bearing 250 and makes it possible to center the second interface plate 25b around the central axis A24, which coincides with the axis of rotation Z, in particular in the assembled configuration of the swing gate 2.

Thus, the bearing 250 constitutes a guide bearing of the second interface plate 25b, therefore of the amount 22, pivoting around the axis of rotation Z.

As visible at , the bearing 250 is stepped. This makes it possible to define the position of the ring 252 along the central axis A24. The part of the bearing 250, which defines the guide bearing for the upright 22, is the part of smaller diameter, which is surrounded by the ring 252, particularly in the assembled configuration of the swing gate 2.

Advantageously, the base 242 further comprises a plurality of openings 256. Each opening 256 is an opening for the passage of a fixing element 246 to the ground of the base 242.

Advantageously, the base 242 comprises several legs 254, in this case three in number. Each of the legs 254 includes at least one of the openings 256.

Here, each opening 256 is a notch for receiving one of the threaded rods 246. Each opening 256 opens outwards, that is to say on the side of the tab 254 opposite the central axis A24.

Thus, the open or opening nature of the openings 256 towards the outside facilitates the installation of the base 242 on the ground, while the threaded rods 246 are already sealed or screwed in place.

In addition, the open or open nature of the openings 256 allows longitudinal adjustment of the position of the base 242 in a direction parallel to the largest dimension of the openings 256.

Advantageously, the base 242 includes several markers 258, in this case four in number. The marks 258 are regularly distributed, in particular at 90°, around the central axis A24 and therefore the axis of rotation Z.

Thus, the marks 258 make it possible to position the retaining device 23 vertically, in particular by means of a laser.

As a variant, not shown, the number of marks is different from four, for example equal to two, three or five.

The base 242 further comprises a circular rack 260. The circular rack 260 is centered on the central axis A24 and therefore on the axis of rotation Z.

A circular rack is a series of indentations arranged one after the other, in other words a succession of indentations, following a circular arrangement, in particular in a regular pitch, the circular arrangement being defined by a fictitious circle.

Here, the circular rack 260 is formed by a succession of hollow housings 262, distributed regularly around the central axis A24, in particular over 360°.

In the exemplary embodiment, the circular rack 260 comprises thirty-six hollow housings 262 spaced angularly, two by two, with an angle α equal to 10° and which form the indentations of the circular rack 260.

Alternatively, the number of hollow housings is different and the value of the angle between two hollow housings is adapted accordingly. The number of hollow housings can be, for example, equal to 24 or 48, in which case the angle α is respectively 15° or 7.5°.

The support device 24 further comprises the stop 264. The stop 264 is immobilized, otherwise is configured to be immobilized, on the base 242, in a predetermined angular position around the central axis A24 and therefore of the axis of rotation Z, by cooperation with the circular rack 260, in particular in an assembled configuration of the support device 24.

Advantageously, the support device 24 further comprises first immobilizing elements.

Here, the first immobilizing elements are reliefs 268. The reliefs 268 are provided on the stop 264 and intended to cooperate, in other words cooperate, with the circular rack 260, so as to block the stop 264 on the circular rack 260, in a direction orthoradial to the axis of rotation Z, in particular in the assembled configuration of the swing gate 2.

Thus, the stop 264 includes the reliefs 268, in other words teeth, visible at the , the geometry and positioning of which are designed so that these reliefs 268 can engage at the same time in adjacent hollow housings 262 of the circular rack 260.

In this way, the cooperation of shapes of the reliefs 268 and the recessed housings 262 makes it possible to block the stop 264 on the circular rack 260 in a direction orthoradial to the central axis A24, therefore to the axis of rotation Z, in particular in the assembled configuration of the swing gate 2.

Advantageously, the stop 264 is a part obtained by metal casting.

Thus, it has high mechanical stability and good resistance to repeated shocks, particularly compared to a staple obtained by bending sheet metal.

In the example of the figures, the stop 264 includes five reliefs 268.

Alternatively, the number of reliefs of the stop is different, for example equal to one, two, three, four or greater and equal to six.

The higher the number of reliefs 268, the better the immobilization of the stop 264 on the circular rack 260, but the more complex the geometry of the stop 264.

In practice, the reliefs 268 of the stop 264 have the same angular spacing between them as the recessed housings 262 of the circular rack 260.

Advantageously, the base 242 further comprises a groove 270, in particular annular.

Here, the groove 270 surrounds the bearing 250 and the marks 258 around the central axis A24, in particular over 360°. Radially to the central axis A24, the groove 270 is located between the marks 258 and the circular rack 260.

Advantageously, the stop 264 comprises a heel 272. The heel 272 is engaged in the groove 270, when the reliefs 268 of the stop 264 are received in the recessed housings 262 of the circular rack 260.

Thus, the heel 272 makes it possible to guide the stop 264 in a rotational movement around the central axis A24, relative to the circular rack 260, when the reliefs 268 are not engaged in the recessed housings 262.

In addition, the heel 272 makes it possible to block the stop 264 relative to the base 242, in particular by wedge effect, as emerges from the explanations which follow.

Advantageously, the support device 24 further comprises a second immobilizing element.

Here, the second immobilizing element is a pressure screw 274. The pressure screw 274 exerts, in other words is configured to exert, on the stop 264 a radial force to the axis of rotation Z.

Thus, the support device 24 further comprises the pressure screw 274. The pressure screw 274 is screwed into a tapped hole 276 of the stop 264 and comes to bear, otherwise is configured to come to bear, against a surface external radial S250 of the bearing 250, when the stop 264 is blocked relative to the base 242.

Here, the surface S250 is not covered by the ring 252 when it is mounted on the bearing 250.

Under the effect of the reaction of the bearing 250, the pressure screw 274 exerts on the stop 264 a radial force on the central axis A24 and therefore on the axis of rotation Z and centrifugal.

In such a configuration shown in particular in Figures 4 to 6, the support of the pressure screw 274 against the surface S250 has the effect of pressing the heel 272 against an external radial edge of the groove 270. This immobilizes the stop 264 on the circular rack 260, in particular by friction and/or by wedge effect, and opposes a possible extraction of the reliefs 268 of the stop 264 relative to the recessed housings 262 of the circular rack 260.

Thus, the stop 264 is firmly immobilized, in a position predetermined by the cooperation of the reliefs 268 and the recessed housings 262, on the base 242.

Depending on the configuration of installation and use of the swing gate 2, the stop 264 can be immobilized on the circular rack 260 in any of the thirty-six predetermined positions defined by the cooperation of the reliefs 268 with the housings in hollow 262.

The support device 24 further comprises the stop pin 280. The stop pin 280 is secured to the upright 22 and is configured to come to bear, in other words to come to bear, against the stop 264, at the end of pivoting travel of the screen 5 around the axis of rotation Z.

Thus, the stop pin 280 has the function of blocking the rotation of the screen 5 around the axis of rotation Z by coming to rest against a lateral surface S264 of the stop 264, when the screen 5 reaches the end of pivoting travel around the axis of rotation Z, in an opening direction, that is to say when the screen 5 reaches its open position.

Alternatively, the stop pin 280 may have the function of blocking the rotation of the screen 5 around the axis of rotation Z when the screen 5 reaches its closed position.

Here, the groove 270 takes up the radial forces at the central axis A24 coming from the stop 264, through the heel 272, and the reliefs 268 of the stop 264 take up the forces coming from the screen 5 when the latter is in the end position, through the stop pin 280.

Advantageously, the stop pin 280 is mounted, in other words is configured to be mounted, on the second interface plate 25b, in particular in the assembled configuration of the swing gate 2. As the second interface plate 25b is fixed to the upright 22, in particular by the fixing screws 27, the stop pin 280 is secured to the upright 22 through the second interface plate 25b.

In a not shown variant of the invention, the stop pin 280 is secured directly to the upright 22, that is to say without passing through the second interface plate 25b.

Advantageously, the stop pin 280 comprises a rod 282, in particular threaded. The rod 282 is configured to pass through, in other words crosses, the second interface plate 25b, in particular through an orifice 284 provided in the second interface plate 25b, in the assembled configuration of the swing gate 2.

Advantageously, the stop pin 280 also comprises a nut 288, in particular braked.

Thus, the nut 288 makes it possible to immobilize the stop pin 280 on the second interface plate 25b.

Here, two washers 284, 286 are provided to be arranged, in other words are arranged, on either side of the second interface plate 25b, along the axis of rotation Z, in particular in the assembled configuration of the swing gate 2.

Advantageously, the stop pin 280, in particular the rod 282, comprises a wedge 290. The wedge 290 is in support, in other words is configured to be in support, against the stop 264, in particular in the assembled configuration of the device. support 24.

The wedge 290 is preferably installed at one end of the rod 282, which constitutes the lower end of the stop pin 280, in particular in the assembled configuration of the support device 24.

Preferably, the rod 282 and the wedge 290 are in one piece.

Alternatively, parts 282 and 290 are manufactured separately and assembled together to constitute the stop pin 280.

We note A280 a longitudinal axis of the stop pin 280, which is a central axis of the rod 282.

Advantageously, the rod 282 is held in position, otherwise is configured to be held in position, on the second interface plate 25b by means of the nut 288, with the possibility of rotation of the wedge 290 relative to the second plate d interface 25b, around the longitudinal axis A280 of the stop pin 280.

Advantageously, the wedge 290 comprises at least a first bearing surface S290A against the stop 264 and a second bearing surface S290B against the stop 264.

We note d_HAS a first distance, measured perpendicular to the longitudinal axis A280, between the first bearing surface S290A and the longitudinal axis A280. This first distance_HAShas a first value.

We note d _B a second distance d _B , measured perpendicular to the longitudinal axis A280, between the second support surface S290B and the longitudinal axis A280. This second distance d _B has a second value. The second value is different from the first value.

Advantageously, the wedge 290 is orientable, otherwise it is configured to be oriented, relative to the longitudinal axis A280, between at least:

- a first angular position, in which the first support surface S290A comes to rest against the stop 264, at the end of the pivoting stroke of the screen 5 around the axis of rotation Z, and

- a second angular position, in which the second support surface S290B comes to rest against the stop 264, at the end of the pivoting stroke of the screen 5 around the axis of rotation Z.

Here, the wedge 290 comprises four bearing surfaces, in particular parallel to the longitudinal axis A280, namely the bearing surfaces S290A, S290B, S290C, S290D visible on the insert A) of the . These bearing surfaces S290A, S290B, S290C, S290D are separated in pairs by chamfers 292. The bearing surfaces S290A, S290B, S290C, S290D are perpendicular in pairs. In other words, each of these bearing surfaces S290A, S290B, S290C, S290D is perpendicular to the two bearing surfaces to which it is connected by a chamfer 292 and parallel to the opposite bearing surface.

In the same way, we note_VS and D_D, third and fourth distances, measured respectively perpendicular to the longitudinal axis A280, between the third support surface S290C and the longitudinal axis A280 and between the fourth support surface S290D and the longitudinal axis A280.

Here, the distances of_HAS, d_B, d_VS, d_Dbetween these bearing surfaces S290A, S290B, S290C, S290D and the longitudinal axis A280, measured perpendicular to the longitudinal axis A280, are different two by two. In other words, the bearing surfaces S290A, S290B, S290C, S290D extend at different distances from the longitudinal axis A280, in the plane of the insert A) at the .

Here, the wedge 290 can be arranged, opposite the longitudinal axis A280, in four positions.

Furthermore, in each of the positions of the wedge 290, one of the bearing surfaces S290A, S290B, S290C, S290D comes to bear, otherwise is configured to come to bear, against the stop 264, at the end of the pivoting stroke of the screen 5 around the axis of rotation Z.

Thus, the stopping position of the upright 22 when the stopping pin 280 comes to bear against the stop 264, is defined by the position of the longitudinal axis A280 with respect to the circular rack 260, it is that is to say by its position around the axis of rotation Z and the central axis A24, which are combined. This stop position corresponds to the open position of screen 2 or, alternatively, to the closed position of screen 2.

In this way, the position of the longitudinal axis A280 relative to the axis of rotation Z and to the central axis A24 depends on the distance between the surface S264 of the stop 264 and the longitudinal axis A280, this distance being equal, in practice, to one of the distances d _A , d _B , d _{C ,} d _D , depending on the orientation of the wedge 290 around the longitudinal axis A280.

Here, the wedge 290 can be arranged, opposite the longitudinal axis A280, in four positions, preferably angularly offset by 90° relative to each other, which each correspond to the facing of one of the bearing surfaces S290A, S290B, S290C, S290D and of the surface S264 of the stop 264.

Thus, by choosing from the support surfaces S290A, S290B, S290C, S290D of the wedge 290 which is arranged facing the surface S264 of the stop 264, it is possible to adjust the position of the stop pin 280, around of the longitudinal axis A280, when this stop pin 280 rests against the stop 264.

The distances of_HAS, d_B, d_VS, d_Dare, preferably, chosen so that the different angular positions of the wedge 290 around the longitudinal axis A280, as a function of the support of the corresponding support surfaces S290A, S290B, S290C, S290D against the surface S264 of the stop 264, correspond to an angular offset of a predetermined value, which may be, for example, 2.5°, between each of the positions.

In other words, by choosing which of the support surfaces S290A, S290B, S290C, S290D is oriented towards the surface S264 of the stop 264, it is possible to define the angular position, around the longitudinal axis A280, of the stop pin 280 against the stop 264, with a predetermined precision, which can be, for example, 2.5° for a number of thirty-six hollow housings 262 of the circular rack 260 or 3.75° for one number of twenty-four hollow housings 262 of the circular rack 260, that is to say by dividing the angle α by four, thanks to the orientation of the wedge 290 around the longitudinal axis A280.

The use of the wedge 290 and the choice of its orientation around the longitudinal axis A280 therefore makes it possible to refine the adjustment precision when the screen 5 is at the end of its stroke, that is to say when the pin stop 280 rests against stop 264.

As the nut 288 is a lock nut, it can be tightened moderately on the rod 282. This allows an installer to manipulate the shim 290 to rotate it about the longitudinal axis A280 when selecting the surface of support S290A, S290B, S290C, S290D which must come to bear against the surface S264 of the stop 264, without having to dismantle the second interface plate 25b relative to the upright 22. This facilitates commissioning of the installation 1.

The rotation of the wedge 290 around the longitudinal axis A280 can be carried out manually by the installer, in particular using a tool, such as, for example, a spanner.

Advantageously, the volume V250 constitutes a passage of the electrical power cable 9 of the electromechanical actuator 4.

Thus, as can be deduced from Figures 1, 2 and 5, the electrical power cable 9 can pass through the pillar 6 or pass through a base not shown, in which the threaded rods 246 are sealed or screwed, then go up into the amount 22 passing into the volume V250 of the bearing 250 and through the opening 25b1 of the second interface plate 25b, to supply electrical energy to the electromechanical actuator 4, in particular its electric motor. The electrical power cable 9 is thus protected against the risk of accidental cutting, including during the pivoting of the screen 5.

Advantageously, the electromechanical actuator 4 further comprises an output shaft 8. The output shaft 8 extends upwards, from the first end 22a of the upright 22.

Advantageously, the output shaft 8 of the electromechanical actuator 4 is aligned on a longitudinal axis A8 coincident with the axis of rotation Z, in particular of the upright 22, in the assembled configuration of the swing gate 2.

Thus, the output shaft 8 of the electromechanical actuator 4, that is to say the shaft constituting a fixed point of the motorized drive device 3, coincides with the axis of rotation Z, in particular of the upright 22.

Here, the electromechanical actuator 4 extends in the direction of the axis of rotation Z.

Advantageously, the first interface plate 25a comprises an opening 34 for the passage of the output shaft 8 of the electromechanical actuator 4.

Thus, the output shaft 8 is arranged at least partly outside the upright 22, in the assembled configuration of the swing gate 2.

Advantageously, the output shaft 8 of the electromechanical actuator 4 is configured to be integral, in other words is integral, with the retaining device 23, in particular in the assembled configuration of the installation 1.

We note A232 a longitudinal axis of the plate 232, which is perpendicular to the bottom plate 232D of the plate 232.

Advantageously, the plate 232 includes a housing 232E. Housing 232E is a housing for receiving one end 8A of the output shaft 8 of the electromechanical actuator 4, extending along the axis of rotation Z, from the first end 22a of the upright 22.

Thus, the end 8A of the output shaft 8 of the electromechanical actuator 4 is engaged and retained, in other words is configured to be engaged and retained, inside the housing 232E, in particular in the assembled configuration of the gate beating 2.

Advantageously, the end 8A of the output shaft 8 of the electromechanical actuator 4 is fixed, in other words is configured to be fixed, to the retaining device 23 by means of at least one element 35, 36, in particular d a screw fixing element, in the assembled configuration of the swing gate 2.

Thus, the plate 232 is equipped with at least a first element 35, 36, the first element 35, 36 being a fixing element, in other words retaining, of the end 8A of the output shaft 8 in the housing 232E.

Advantageously, the end 8A of the output shaft 8 is provided with two flats 8C, one of which is visible at the .

We denote D ₈ as the diameter of the output shaft 8, measured parallel to the flats 8C, and l ₈ as the width of the output shaft 8, measured between the flats 8C.

We note l 232 the width of the housing 232E measured perpendicular to the longitudinal axis A232.

Here, the width l 232 is strictly greater than the width l₈ and strictly less than diameter D₈. This imposes the angular orientation of the output shaft 8 around the axis of rotation Z when its end 8A is received in the housing 232E.

Here, the end 8A of the output shaft 8 of the electromechanical actuator 4 is retained in the housing 232E by means of a fixing screw 35 and a nut 36. The fixing screw 35 is mounted through of a passage opening 8B made in the output shaft 8 of the electromechanical actuator 4 and passes through two passage holes 232F made in the plate 232, with the interposition of two washers 37, 38. Then, the nut 36 is screwed onto the fixing screw 35 until it comes under pressure on the plate 232.

To the , the screw 35, the nut 36 and the washers 37, 38 are shown in the position they occupy when the output shaft 8 is retained in the housing 232E, but the output shaft 8 is not shown .

Advantageously, the plate 232 is in one piece.

Advantageously, the plate 232 further comprises an opening 232G, which makes it possible to lighten it, without significantly reducing its mechanical properties.

Along the longitudinal axis A232, the opening 232G is preferably arranged between the housing 232E and the bottom plate 232D.

Advantageously, the plate 232 further comprises a stiffening rib 232H, which surrounds the opening 232G and which connects to the bottom plate 232D.

Here, the passage holes 232F are oblong, with their greatest direction parallel to the longitudinal axis A232. This allows adjustment of the position of the output shaft 8 in the housing 232E, parallel to this longitudinal axis A232. Once this adjustment has been made, tightening the nut 36 allows the fixing screw 35 to be maintained in position relative to the plate 232.

Advantageously, the plate 232 is equipped with at least a second element 238. The second element 238 is an element for adjusting the plumbness of the screen 5, in particular by bearing on the end 8A of the shaft of output 8 arranged in housing 232E of plate 232.

Here, the second element 238 is a pressure screw. The pressure screw is screwed into a tapped hole 232J of the plate 232. This makes it possible to immobilize the output shaft 8 in the housing 232E, resting against a wall of the plate 232, in particular which separates the housing 232E from opening 232G.

Advantageously, the pressure screw forming the second element 238 makes it possible to adjust the plumbness of the screen 5, in particular quickly and precisely, before locking in position the output shaft 8 in the housing 232E of the plate 232, by the first element consisting of the fixing screw 35 and the nut 36.

Advantageously, the plate 232 further comprises a surface S232, in particular flat. Surface S232 is a one-level support surface, not shown, in the mounted configuration of the plate 232 on the pillar 6.

Thus, the surface S232 is intended to support a level. This makes it possible to adjust the positioning of the plate 232 on the pillar 6 before tightening nuts on the threaded rods 236, by moving the plate 232 if necessary until the level indicates that the surface S232 is horizontal. This ensures correct positioning of the plate 232, in particular the fact that the housing 232E is correctly oriented so that the output shaft 8 is received there with its longitudinal axis A8, in particular vertical.

Advantageously, a washer 237 and a spacer 239 are interposed, along the axis of rotation Z, between the first interface plate 25a and the plate 232.

Thus, this washer 237 and this spacer 239 surround the end 8A of the output shaft 8 and protect against bad weather and pollution by closing the opening 34 and the passage openings 178.

Advantageously, the plate 232 is made by molding metal, in particular steel or an aluminum alloy, or by molding synthetic material, in particular a composite material.

Its geometry allows it to have good resistance to the forces experienced in the static configuration of the swing gate 2, as well as during its pivoting movements, while minimizing the quantity of material used.

Thanks to manufacturing by casting, the cost of obtaining this 232 plate is well controlled. The casting process is particularly advantageous in this regard, compared to a machining process.

Alternatively, the plate 232 can be made partially by molding, with one or more machining steps, in particular to produce the housing 232E or the tapped hole 232J.

Advantageously, the plate 232 further comprises at least a first relief 232K, 232L, 232M. The cover 234 comprising at least a second relief 234A, 234B, 234C. In addition, the cover 234 is held, in other words is configured to be held, on the plate 232 by cooperation of shapes of the second relief 234A, 234B, 234C with the first relief 232K, 232L, 232M, in particular in an assembled configuration of the retaining device 23.

Here and as illustrated in , the cover 234 comprises a projecting element 234A and two tongues 234B, 234C, forming second reliefs of the cover 234. The bottom plate 232D of the plate 232 comprises a notch 232K and two slides 232L, 232M, forming first reliefs of the plate 232. The notch 232K and the slides 232L, 232M are configured to receive, in other words receive, respectively the projecting element 234A and the two tabs 234B, 234C, in the mounted configuration of the cover 234 on the plate 232.

Advantageously, when the plate 232 is fixed on the pillar 6 and the output shaft 8 of the electromechanical actuator 4 is secured to the plate 232, by means of the first and second elements 35, 36, 238, the cover 234 is attached on the plate 232 by a simple vertical translation directed downwards, represented by the arrow F11 at the . This translation is carried out parallel to the face of the pillar 6 on which the plate 232 is fixed.

Thus, the first reliefs 232K, 232L, 232M, on the one hand, and the second reliefs 234A, 234B, 234C, on the other hand, guide and retain the cover 234 on the plate 232 by cooperation of shapes.

In addition, such mounting of the cover 234 on the plate 232 allows easy access to an unlocking device 26, as described below, by removing the cover 234 relative to the plate 232, in a movement opposite to that shown by arrow 11, in particular without using a tool.

Advantageously, the electromechanical actuator 4 further comprises a reduction gear not shown.

Advantageously, the reducer comprises at least one reduction stage. This reduction stage can be an epicyclic type gear train.

The type and number of reduction stages of the gearbox are not limiting.

Advantageously, the reducer is of the reversible type.

The gearbox is configured to be mounted, in other words is mounted, between the electric motor and the output shaft 8, in particular in an assembled configuration of the electromechanical actuator 4.

The electric motor is configured to reversibly drive the output shaft 8 in rotation, through the reduction gear, and, more particularly, the screen 5, that is to say in a clockwise direction of rotation and in a counterclockwise direction of rotation.

Advantageously, the motorized drive device 3 further comprises the unlocking device 26.

The unlocking device 26 is configured to be accessible, in other words is accessible, in particular in the assembled configuration of the swing gate 2, so as to allow the screen 5 to be manually moved relative to the fixed structure, in particular the pillar 6 of the fence, particularly in the event of breakdown of the electromechanical actuator 4 or interruption of its electrical supply.

The end of travel established by the cooperation of the stop 264 and the stop pin 280 of the support device 24, remains active even in the event of manual operation of the screen 5, after use of the unlocking device 26.

Advantageously, the unlocking device 26 is configured to be arranged, otherwise is arranged, at least partly inside the upright 22, in particular in the assembled configuration of the swing gate 2.

Thus, the unlocking device 26 is hidden at least partly inside the upright 22, so as to improve the aesthetic appearance of the installation 1.

Advantageously, the electromechanical actuator 4 further comprises a brake not shown, in particular an electrobrake.

Thus, the brake makes it possible, in particular, to block the motorized drive device 3, in particular the electromechanical actuator 4, when the screen 5 is in the closed position.

Here, the electrobrake is configured to be mounted, in other words is mounted, on the electric motor of the electromechanical actuator 4, in particular on a housing of the electric motor, in the assembled configuration of the electromechanical actuator 4.

Thanks to the present invention, the base, which is located under the upright and which supports it, defines both the guide bearing of the upright in pivoting and means for fixing the end of pivoting stroke stop of the screen.

In this way, the support device is compact and is arranged at the foot of the upright, ensuring a triple function of taking up the weight of the screen, guiding the screen in pivoting and delimiting an end position. screen stroke.

Furthermore, the stop pin ensures an end-of-stroke function without extending radially from the screen upright while the base is placed under this upright. This makes it possible to limit the bulk of the support device.

Advantageously, the shim mounted on the stop pin makes it possible to improve the precision of the definition of the end position of the screen.

Numerous modifications can be made to the exemplary embodiments described above, without departing from the scope of the invention.

The invention is described above and represented by the figures in the case where it includes a motorized drive device 3 comprising an electromechanical actuator 4. The invention is however applicable to an installation 1 devoid of the motorized drive device 3 , that is to say in which the screen 5 is moved by hand. In this case, the output shaft 8 which extends along the axis of rotation Z, from the first end 22a of the upright 22 is a shaft movable in rotation relative to the first interface plate 25a, in particular through a landing.
