DETAILED DESCRIPTION OF THE INVENTION

With reference to FIG. 1, a sliding gate 1 comprises a leaf 2, a module 3 forming an upright, and a striker 4.

The leaf 2 is movable in translation relative to the striker 4, in a Y sliding direction parallel to the ground, so horizontal, when the gate 1 is mounted and ready for operation.

The leaf 2 comprises a plurality of crosspieces 20, 21 extending horizontally, for example a lower cross member 21 and a high cross member 20. The leaf 2 further comprises a plurality of posts 22 extending perpendicular to the crosspieces 20, 21, vertically compared to the ground. Each upright 3 connects the lower rail 21 to the upper rail 20.

The leaf 2 has a free end portion 24 opposite the striker 4. This end portion 24 is for example formed by an end post 22 and / or end portions of the struts 20, 21.

The free end portion 24 has in particular two opposing front and rear surfaces, visible when viewing the leaf 2 from the front. The opposite surfaces are flat and parallel to the horizontal direction. The free end portion 24 also has a surface 26 facing the column, flat and normal to the horizontal direction of sliding indicated by the Y axis.

The module 3 in the form of upright comprises a housing 30 fixed on the front surface or on the rear surface of the end portion 24 of the leaf 2 by means of suitable fastening means (not shown).

The housing 30 is of elongated shape along a longitudinal axis corresponding to the Z axis after its mounting leaf 2. The housing is for example of parallelepiped shape. By convention, the length of the module 3 is defined as its dimension along the Z axis, its width as its dimension along the Y axis and its thickness as its dimension along the X axis.

Advantageously, the length of the housing 30 of the module 3 is substantially equal to the length of the end portion 24 of the leaf 2, and / or the width of the housing of the module 3 is substantially equal to the width of the end portion 24 leaf 2, which improves the aesthetics of the whole.

Furthermore, the striker 4 is adapted to be mounted on a column (not shown for better readability of the figures) which is fixed relative to the ground. In a manner known per se, the striker 4 comprises a plate 40, for example metal, in which is formed an orifice 42 adapted to receive a bolt of the gate 1 to retain the bolt so as to block the leaf 2 along the Y axis of sliding. This bolt will be described in more detail later.

The plate 40 is attached to the column via appropriate fastening means such as screws. After fixing to the column, the plate extends vertically with respect to the ground.

The plate further comprises a second port 43, and an electrical connection port 44 adapted to be connected to an external power source (not shown), for example a photovoltaic panel.

Referring to Figure 2, the housing 30 of the module 3 comprises two parts: a female or external part 30a, and a male or internal portion 30b which is inserted into the female part 30a to close the housing 30. The male part a U-shaped profile following a horizontal section plane.

The module 3 comprises a locking device 5 of the gate 1, a battery pack 6, a control device 7, and a motorized device 8 for moving the leaf 2.

In the embodiment illustrated in FIG. 2, the locking device 5, the battery 6, the control device 7 and the motorized device 8 are all aligned longitudinally, for example in this order from top to bottom, when the module is fixed to the leaf 2 of the gate 1. The module 3 and has a minimum width and thickness, which allows integration of the module 3 on gates 1 whose amounts are narrow without compromising the aesthetics of the whole.

The motorized device 8 comprises a motor 80, a gearbox 82 and a wheel 84.

The wheel 84 is rotatable relative to the housing 30. The wheel 84 at least partially protrudes from the housing 30. The wheel 80 is arranged in the housing 30 so as to rest on the ground when the module 3 is fixed to the leaf 2. The motor 80 configured to drive the wheel 84 in rotation. The reducer 82 is configured to transmit the movement of a drive shaft of the motor 80 (not visible in the figures) to the wheel 84.

Moreover, the control device 7 comprises wireless communication means. The communication means comprise for example an infrared sensor or a radio signal receiving antenna. The control device 7 is configured to control the motor 80 according to commands received by the wireless communication means previously transmitted by a remote control.

The locking device 5 is an autonomous unit forming a housing 50, housed at least partially within the module 3. The device 5 is fixed to the housing 50 of the module 3 with the aid of suitable fixing means.

The housing 50 of the locking device 5 has an oblong shape parallel to a longitudinal axis; it is for example parallelepipedic. When the locking device 5 is fixed in the housing 30 of the module 3, and the module 3 is itself fixed to the end portion 24 of the leaf 2, the longitudinal axis is oriented vertically relative to the ground (parallel to the Z axis).

With reference to FIG. 3, the locking device 5 comprises a bolt 52 and at least one actuating system, or actuator, for moving the bolt.

The bolt 52 is mounted to move in translation relative to the housing 50 parallel to the longitudinal axis, and thus vertically after attachment of the locking device 5 to leaf 2 of the gate 1. This bolt 52 is movable between two positions: a locked position and a unlocked position. By convention, it is considered that these two positions implicitly refer to the locking of the device 5 with the striker 4.

As will be seen in the following, the direction in which the bolt moves in translation is perpendicular to the sliding direction of the gate 1. The direction in which the bolt moves is a vertical direction after mounting the gate 1. The position locked is a low position of the bolt 52 and the unlocked position is a high position of the bolt 52, when the locking device 5 is mounted at the gate 1.

The housing 50 has a wall intended to be opposite the keeper 4 after mounting the gate 1. In this wall is defined an orifice 53.

The bolt 52 comprises a hook projecting from the housing via the orifice 53.

More specifically, the bolt 52 includes an inner portion 520, a transverse portion 521 extending the inner portion 520, and an end portion 522 extending the transverse portion 521.

The inner part 520 is located inside the housing. The inner portion 520 extends parallel to the longitudinal axis (thus vertically after mounting the gate 1). It is arranged to be biased in displacement along the longitudinal axis by the or each actuator. The inner portion 520 is pierced with a hole 524 transverse to the axis of its axis of displacement.

The transverse portion 521 extends across the orifice 53, transversely to the longitudinal direction. The transverse portion extends more precisely along the direction of sliding of the gate, perpendicularly to the inner portion 521. The transverse portion 521 projects partially out of the casing 50.

The end portion 522 of the bolt 52 is bent with respect to the transverse portion 521. The end portion is outside the housing 50. The hook of the bolt 52 is formed by the transverse portions 521 and at least 522 end. The hook 522 is of dimensions adapted to cross the orifice 42 of the plate 40. When the locking device 5 is fixed to the gate 1, the end portion 522 is turned towards the ground. The direction towards which the end portion 522 is bent is a direction of movement of the bolt 52 from its unlocked position to its locked position. This direction is a direction oriented towards the ground after attachment to the gate 1, in the illustrated embodiment.

The end portion 522 has a first surface 5220 and a second surface 5221.

The first surface 5220 is a surface positioned to abut against the striker 4, to prevent sliding of the gate 1 when the hook is engaged in the orifice 42. The first surface 5220 is arranged facing the housing 50. The first surface 5220 is for example a flat surface extending in a plane normal to the sliding axis of the gate 1 (thus a vertical plane after mounting the locking device 5 to the gate 1), or slightly inclined relative to this plane as shown on the figures.

The second surface 5221 is a surface positioned to bear against a rim 420 of the orifice 42 formed in the plate 40 of the striker. The second surface 5221 is also oriented to move the bolt 52 to the unlocked position, when, said surface 5221 bearing against the rim of the orifice 42, the locking device 5 is moved towards the striker in the direction of sliding Y, by sliding the surface 5221 against the rim of the orifice. The second surface is curved. Alternatively, the second surface is flat but oriented in a direction not parallel to the longitudinal direction.

The stroke of the bolt 52 is limited by the casing 50. The wall of the casing in which the orifice 53 is formed serves as a stop limiting the stroke of the transverse part of the bolt 52, and / or other walls of the casing 50 are limit stop to limit the stroke of the inner part of the bolt 52.

In the embodiment shown in the figures, the locking device 5 comprises two actuators for moving the bolt 52: a motorized actuator, thus comprising a motor 51, and a lock 55 with manual key. The bolt 52 can thus be moved in two different ways: either with the aid of a manual key, or by putting the motor 51 into operation. The motorized actuator is for example formed by a jack 510 comprising the motor 51. motorized actuator and the bolt 52 are arranged in different positions along the longitudinal axis (the vertical axis Z when the device 5 is fixed to the leaf 2). This makes it possible to limit the size of the locking device 5 in a plane perpendicular to the longitudinal direction (this plane being defined by the horizontal axis X and the Y axis of sliding of the leaf 2 when the device 5 is fixed to the leaf 2 ). In the embodiment illustrated in the figures, the bolt 52 is disposed in the casing 50 so as to be above the motorized actuator, and in particular above the motor 51, when the locking device 5 is fixed to the leaf 2.

The cylinder 510 is of the 12-volt DC type. The cylinder 510 comprises a cylinder (not shown in the figures) fixed relative to the housing 50 and a piston movable in translation relative to the cylinder. The piston is fixed to the inner part 520 of the bolt 52. The motor 51 is configured to move the piston in translation relative to the cylinder, and consequently to translate the bolt 52 in translation relative to the casing 50.

The motor 51 is supplied with electricity by the power supply battery 6 of the module 3 via electrical wires. A single battery 6 is used to supply electricity to the motors 51 and 80, which makes it possible to limit the bulk of the unlocking device 5 and, more generally, of the module 3.

The locking device 5 furthermore comprises electrical wires for connecting the control device 7 to the motor 51 of the locking device 5. The control device 7 is configured to control the motor 51 according to commands received by the communication means without 3 module thread already mentioned.

The locking device 5 further comprises an electrical connection port 54. The port 54 is formed on a face of the housing 50 facing the electrical port 44 formed on the plate 40, which is connected to an external power source. The port 54 is positioned to be brought into contact with the port 44 of the plate when the bolt is engaged in the hole 42 of the striker. The port 44 and / or the port 54 can thus comprise two retractable pads to guarantee a mutual contact of the ports 44, 55.

In the embodiment illustrated in FIGS. 3 to 5, electrical wires connect the connection port 54 to the battery pack 6. The electrical connection port 54 constitutes a port through which the battery 6 can be recharged.

The power supply battery 6 of the motor 51 is located in the housing of the module 3 and outside the housing of the locking device 5. The electrical wires connecting the charging port 54 to the battery 6 extend through an orifice 500 formed in the housing 50 of the locking device 5, as well as the electrical son connecting the battery 6 to the motor 51.

The lock 55 with manual key is for example a cylinder lock 55. The lock 55 manual key is arranged between the intermediate portion 521 of the bolt and the motor 51. The barrel is accessible from outside the housing 50 through an opening 550 formed in the housing 50. The lock 55 key manual includes a push 552 configured to move in translation the bolt 52 when a key is inserted and turned in the barrel. The lock 55 extends into the housing 50 through the transverse orifice 524 formed in the inner portion 520 of the bolt 52. The pusher 552 urges an edge of this orifice 524 to move the bolt, when the key is turned in the lock 55.

The locking device 5 further comprises a return member 57 configured to bias the bolt 52 to its locked position. The return element 57 is housed inside the housing 50. It is fixed on the one hand to a wall of the housing 50 and on the other hand to the inner part 522 of the bolt 52. The return element 57 comprises for example a spring that works in compression.

The locking device 5 further comprises a member 56 projecting towards the striker 5 after mounting the gate 1. More specifically, the element 56 is arranged to be engaged in the hole 43 formed in the plate 40. This element 56 presents a free end of frustoconical shape, providing a guiding function of the housing 50 of the locking device 5 relative to the plate 40 of the striker 4 when closing the gate 1.

With reference to FIGS. 4 and 5, the operation of the sliding gate 1 according to this embodiment is as follows.

It is assumed that the gate 1 is initially in an open position: leaf 2 is at a distance from the column.

A remote control emits a command to close the gate 1, which is picked up by the wireless communication means of the module 3. From the closing command received, the control device 7 drives the motor 80 to turn the wheel 84 into position. rotation, so that the leaf 2 moves in horizontal translation towards the column comprising the striker 4.

During the displacement of the leaf 2, the outer surface 5221 of the hook bears against the rim 420 of the striker 4, which causes the vertical lifting of the hook and more generally of the bolt 52 until the bolt is positioned in the unlocked position. During this uplift, the return element 57 works in compression. Figure 4 shows the bolt in the unlocked position (although the device 5 is shown in this figure remote from the latch 4 for better readability).

During the movement of the leaf 2, the hook 522 engages the keeper 4 through the orifice 42, until the casing 50 of the locking device 5 comes into abutment against the plate 40, and in particular until ports 44 and 54 are electrically connected.

Once the hook has been fully engaged in the orifice 42, the bolt 52 then moves naturally to its locked position, by biasing the spring 57 towards the inner portion 520 of the bolt 52. The hook 522 of the bolt 52 then drops to the interior of the striker 4, so that the transverse portion of the bolt 521 abuts against the lower edge 420 of the orifice 42. The plate 40 engages with the abutment surface 5221 of the hook 522, which blocks leaf 2 relative to the striker along the horizontal sliding axis Y. The gate 1 is then closed, as shown in Figure 5.

As long as the gate remains closed, the battery 6 can then be recharged by the electrical source to which the ports 44 and 54 are now connected.

To open the portal 1, the remote control emits an opening command of the gate 1, which is picked up by the wireless communication means of the module 3. From the received opening command, the control device 7 activates the motor 51 so as to move the bolt 52 to its unlocked position and keep it there despite the force exerted on the bolt by the return element 57.

The control device 7 then drives the motor 80 to turn the wheel 84 in rotation, so that the leaf 2 moves away from the column comprising the striker 4.

Finally, the control device 7 deactivates the motor 51 so that the bolt 52 naturally moves to its lower position, by biasing the bolt 52 by the return element 57.

FIGS. 6 and 7 show a second embodiment of the module 3, comprising no return element 57 to the locked position of the bolt 52, and in which the motor 51 operates differently from the first embodiment described previously. .

In this second embodiment, the device comprises locking means 58 of the bolt 52 in its unlocked position.

The locking means 58 comprise a return element 580, a ball 581, and a cavity 582 opening into a surface of the bolt 52.

The cavity is more precisely formed in a longitudinal surface of the inner portion 520 of the bolt 52. The cavity 582 is of suitable dimensions to receive the ball 581. The ball arranged 581 is arranged opposite the cavity 582 when the bolt is positioned in its unlocked position. The return element 580, for example a helical spring, extends transversely to the direction of movement of the bolt 52, for example parallel to the axis X. The return element 580 has a first end fixed to the housing 50 and a second end attached to the ball 581. The biasing member 580 is configured to bias the ball 581 toward the surface in which the cavity 582 is formed. When the bolt is not in its unlocked position, the spring thus urges the ball towards the bolt 52 so that the ball bears against the surface of the bolt 52. When the bolt reaches its unlocked position, the return element 580 pushes the ball 581 inside the cavity 582 which is opposite, which makes it possible to block the movement of the bolt 52. When the unlocked position of the bolt 52 is a high position, the return element 580 is chosen to present sufficient stiffness to maintain the bolt 52 in this high position despite the weight of the bolt.

The operation of the sliding gate 1 according to the second embodiment is as follows. It is assumed that the gate 1 is initially closed: the leaf 2 is against the column, the end portion of the hook bolt 52 is engaged with the latch 4 through the orifice 42 in the locked position, and the ports 44 and 54 are in electrical connection.

To open the portal 1, the remote control transmits an opening command of the gate 1, which is picked up by the wireless communication means of the module 3. From the received opening command, the control device 7 controls the motor 51 so as to move the bolt 52 to its unlocked position.

When the bolt 52 reaches the unlocked position, the ball 581 urged by the return member 580 enters the cavity 582 facing formed in the bolt 52, which allows to lock the bolt 52 in the unlocked position. After penetration of the ball 581 in the cavity 582, it is no longer necessary to use the motor 51 for this blocking, since it is provided by the means 58. Due to the absence of feedback generated by a biasing element, a brief electric pulse is sufficient to cause the motor 51 to move the bolt 52 from its locked position to its unlocked position, which is particularly economical in electrical energy.

The control device 7 then drives the motor 80 to turn the wheel 84 in rotation, so that the leaf 2 moves away from the column comprising the striker 4.

The closure of the gate 1 is implemented in substantially the same manner as for the first embodiment previously described, except that when the hook has been fully engaged in the orifice 42 (and the connectors 44, 54 are electrically connected), the control device 7 drives the motor 51 to move the bolt 52 from the unlocked position to the locked position. During the movement of the bolt 52, the ball 581 exits the cavity 582 so that the return member 580 works in compression in the locking position. Again, all that is required is a short impulse with polarity inversion at the motor 51 to ensure that the bolt 52 moves from the unlocked position, while the ball 581 engaged in the cavity 582, to the locked position, in which the ball 581 is no longer in the cavity 582.

An advantage of this second embodiment is that it is not mandatory to use the battery 6 to supply electricity to the motor 51 of the locking device 5. It may indeed be provided that the motor 51 is connected directly to the loading port 54 by electrical wires. Thus, the motor 51 is supplied directly with electricity by the external energy source, to which the port 44 of the striker 4 is connected. The invention may be the subject of other variants. For example, the module 3 can be fixed not on the front or rear surface of the end portion of the leaf 2, but on the surface of this end portion facing the column, as shown in FIG. In this case, the module forms an extension of the gate in the direction of sliding parallel to the Y axis. The thickness of the leaf (along the X axis) can thus remain the same as before fixing the module 3 forming the upright.

In another variant not shown, the module 3 forming an amount is located inside the leaf 2.
