Description

Gate with two pivoting leaves with integrated wicket door

The present invention relates to a gate comprising two pivoting leaves and a gate for the passage of a pedestrian.

Access to a closed property can be made for a vehicle by crossing a gate and for a pedestrian by crossing a gate. These two accesses can be differentiated. However, in this case, this supposes having sufficient space in the wall or fence surrounding the property to install both a gate and a gate. In new constructions, this is rarely the case and the access to the road is often of a width limited to that authorizing the passage of a vehicle.

Also known from the state of the art, carriage doors with two pivoting leaves, one of the leaves of which includes a cutout, in which a gate is installed for the passage of a pedestrian.

However, the pedestrian must step over a low crosspiece located at the base of said cutout. This low crossbar does not allow or makes it difficult for a wheelchair to pass.

In addition, the gate must be high enough so that the upper crosspiece (i.e. the part of the leaf located above the cutout) is itself high enough so that the pedestrian does not bump into it. head when going through the gate. However, some users wish to have a gate with two pivoting leaves, provided with a gate, but that the overall height of the gate is not too great, for example at the entrance to a garden pavilion.

An object of the invention is to provide a gate with two pivoting leaves, equipped with an integrated gate which allows pedestrian access and which has neither high crosspiece nor low crosspiece.

Another object of the invention is to provide a gate whose leaves are motorized, while leaving the possibility of manually maneuvering the gate integrated into this gate.

It is for this purpose proposed, according to a first aspect of the invention a gate comprising two fixed supports, a first leaf and a second leaf, each leaf comprising two opposite vertical end edges, called "first edge" and "second edge ", each leaf being pivotally mounted relative to one of said fixed supports, around a vertical pivot axis extending along its first edge and each leaf being provided with an electric motorization device, this device electric motor allowing the two leaves to pivot around their respective pivot axes between a so-called "open" position, in which the two leaves are spaced apart from each other so as to free the passage between the two fixed supports, and a so-called "closed" position, in which they lie in the same plane.

In accordance with the invention, this portal comprises:

-a pedestrian gate, supported by said first leaf and movable relative thereto, either by pivoting around a vertical axis extending along the second edge of the first leaf, or by sliding relative to this first leaf in a plane parallel to the latter, so that said gate can be moved to occupy either a so-called "open" position, in which it is moved away from the second leaf when the latter is in the closed position, so as to allow passage said pedestrian, or a so-called "closed" position, in which it extends in the same plane or in a plane parallel to that of the said first leaf and in the extension or substantially in the extension of the said first leaf,

- a first electrical device for locking the gate in the closed position on said second leaf in the closed position, and
-a central control unit configured to successively actuate the unlocking of said first electric locking device, then the opening of the two leaves using the electric motorization device or, conversely, successively the closing of the two leaves using the locking device electric motorization, then the locking of said first electric locking device.

Thanks to these characteristics of the invention, and to the fact that the gate is directly supported by said first leaf and is mounted either sliding or pivoting around a vertical axis extending along the second vertical edge of the first leaf, c ie at the end of it and not in a cutout of the leaf, it is no longer necessary to have a high crosspiece and a low crosspiece as in the state of the art.

Since the gate is integrated into the gate, this saves the cost of constructing the structural work by eliminating an additional pillar which is otherwise generally built between the gate and the gate, when these are separated.

This gate makes it possible to guarantee the two functions of passage of a vehicle when the two leaves are open and of passage of a pedestrian when only the gate is open, including when the space between the two pillars between which the gate is mounted is relatively restricted.

According to other advantageous and non-limiting characteristics of the invention, taken alone or in combination:

- said first electric locking device comprises an electric strike fixed to the second leaf and a main bolt arranged on the door so as to be able to project from an edge of one of the two vertical edges, called "second edge" of the door, said main bolt and said electric strike being arranged facing each other, so that when said electric strike is electrically activated it occupies a locking position, in which it receives and holds the main bolt and when it is deactivated electrically, it occupies an unlocked position, in which it is erased so as to release said main bolt;

- the gate is provided with at least one return device which constantly tends to bring it back to the closed position;

- The gate is pivotally mounted with respect to the first leaf and said return device is a return spring hinge, which is fixed between the gate and the first leaf, this spring constantly tending to return the gate to the closed position;

- it comprises a second device for locking the gate in the closed position on said first leaf;

- Said second locking device is electromagnetic;

- said second locking device comprises an electromagnet and a ferromagnetic shoe, the electromagnet being placed on the first leaf and the ferromagnetic shoe being placed on the door and facing the electromagnet when the door is in the closed position, so that when the electromagnet is supplied with electricity, it attracts the ferromagnetic slider and locks the gate in the closed position on said first leaf and when it is not supplied with electricity, it does not attract the ferromagnetic slider and unlocks the gate in relation to the first leaf;

- said central control unit is configured to successively actuate the locking of the second locking device then the unlocking of the said first electric locking device then the opening of the two leaves using the motorization device or conversely successively the closing of the two leaves using the motorization device, then the locking of said first electric locking device, then the unlocking of the second locking device, so that during the opening or closing movement of the leaves, the gate is in the extension or substantially in the extension of said first leaf and is immobilized with respect thereto;

- the gate is pivotally mounted with respect to the first leaf, the gate comprises a second device for locking the gate in the closed position on said first leaf, said second locking device comprises a fixed keeper, fixed to the first leaf and a secondary bolt arranged on the gate, said secondary bolt being movable in translation between a so-called "locking" position, in which it protrudes from the edge of one of the two vertical edges, known as the "first edge", of the gate and enters said strike plate fixed, so that said gate is locked in the closed position and extends in the same plane or in a plane parallel to that of said first leaf and a so-called "unlocking" position, in which it is erased inside the gate and does not cooperate with said fixed keeper, the passage of the secondary bolt from one position to the other being ensured by a handle;

- said main bolt is movable in translation between a so-called "locking" position, in which it protrudes from the edge of the second edge of the gate and enters said electric strike and a so-called "unlocking" position, in which it is erased inside the door and does not cooperate with said electric strike, the passage of the main bolt from one position to the other being ensured by a handle;

the secondary bolt (82) and the main bolt (62) are movable together by means of a handle (47, 48) so that they are simultaneously in the locking position or simultaneously in the unlocking position.

Other characteristics, objects and advantages of the invention will emerge from the description which follows, which is purely illustrative and not limiting, and which must be read in conjunction with the appended drawings in which:

In all the figures, similar elements bear identical references.

In the description and the claims, the terms "vertical" and "horizontal" are to be interpreted by reference to the normal position of a gate, when it is mounted in a space provided in a wall or a fence.

In Figures 1 and 2, one can see a gate 1 according to the invention, intended to be installed between two fixed supports 10, which provide between them a space E allowing the passage of a vehicle.

The fixed supports 10 are fixed to the ground.

According to the different existing configurations, the two fixed supports 10 can be an integral part of the wall or of the fence in which the space E is created or they can be constituted by additional structural elements, such as posts or pillars vertical, for example made of metal, wood or plastic.

The gate 1 comprises two pivoting leaves, namely a first leaf 2 and a second leaf 3 allowing the passage of a vehicle and a gate 4 allowing the passage of a pedestrian. The gate 4 is arranged between the two leaves 2 and 3 and preferably in the center of the space E for aesthetic reasons. One of the two leaves could however be wider than the other and the gate 4 would then be off-centre.

Figure 1 shows the gate seen from the outside (street side) and Figure 2, the gate seen from the inside.

Each leaf 2, 3 comprises two opposite vertical end edges, namely a first vertical edge 21, respectively 31, and a second vertical edge 22, respectively 32.

In the example shown in the figures, these vertical edges correspond to vertical uprights of the leaves.

The first leaf 2 is pivotally mounted along its first vertical edge 21, around a vertical axis Y1-Y'1 which extends along this first edge 21 and which is materialized for example by at least two hinges 23. Similarly, the second leaf 3 is pivotally mounted along its first vertical edge 31, around a vertical axis Y2-Y'2 which extends along this first edge 31 and which is materialized for example by at least two hinges 33.

Thus, the two leaves 2, 3 can pivot between a so-called "open" position shown in Figure 4, (it being understood that the leaves can even be completely open until they are parallel to each other) and a position called "closed" shown in Figures 1 to 3 and vice versa. In the closed position, the leaves 2, 3 are in the same plane, in the open position, they are separated from each other and free the passage E, so that a vehicle can pass.

In addition, leaves 2 and 3 are each equipped with an electric motorization device 5, which makes it possible to rotate them automatically between these two positions. The device 5 comprises for example, in a conventional manner, a motor 51 and connecting rods 52, as can be seen better in FIG. 2, one of the motors possibly being a master motor and the other a slave motor slaved to the master motor.

The gate also comprises a central control unit 53, represented schematically in FIG. 2 and which is configured to control in particular the operation of the motors 51 and the opening and closing of the leaves 2 and 3, as will be described further below. detail later. The connections between this central control unit 53 and the motors 51 can be made by wire or not.

The door 4 is a panel which has two vertical end edges 41, 42 and two opposite faces, respectively inner 43 and outer 44. The door 4 is supported by the first leaf 2 and it is movable relative to the latter, either by pivoting around a vertical axis Y3-Y′3 extending along the second vertical edge 22 of the first leaf 2, or by sliding relative to this first leaf, in a plane parallel thereto.

Thus, whatever its mode of movement, the gate 4 can be moved to occupy either a so-called "open" position, in which it is separated from the second leaf 3 when the latter is in the closed position, so as to leave the passage to a pedestrian, or a so-called "closed" position, in which he extends in the same plane or in a plane parallel to that of the leaf 2 and in the extension or substantially in the extension of this leaf 2. In this closed position, it also closes off the space between the two leaves 2 and 3, if these two leaves are themselves in the closed position.

Figure 3 illustrates the open position of the door 4, when the latter is pivotally mounted relative to the first leaf 2.

Figures 1, 2 and 4 illustrate the position of the gate 4, when the latter is in the closed position.

In Figure 4, it can thus be seen that the gate 4 extends in the extension of the first leaf 2, even though the latter is in the process of being opened.

The gate 4 is supported at the end 32 of the first leaf 2 and when it is closed and the second leaf 3 is also closed, it is locked directly on the latter, as will be explained later. Thus, contrary to the state of the art, the gate 4 is not positioned in a cutout made in one of the leaves, so that the gate 1 has neither high crosspiece above the gate 4, nor crosspiece bass below it. The passage of the pedestrian, even of a wheelchair, is facilitated.

The first embodiment of the gate 4, according to which it is pivotally mounted relative to the first leaf 2, will now be described in more detail in connection with Figures 3 and 5 to 7.

As explained above, the gate 4 is pivotally mounted around a vertical axis Y3-Y'3. This assembly can for example be carried out using at least two hinges or hinges 24, arranged in the upper and lower part of the gate 4.

Preferably, a part 24a (male or female) of the hinge or hinge pin 24 is fixed along the second vertical edge 22 of the first leaf 2 and a part 24b (female or male) is fixed to the gate 4.

The vertical axis Y3-Y'3 thus passes through the two hinges 24.

In the embodiment of the invention represented in FIGS. 5 to 7, it will be noted that the gate 4 is offset from the exterior side EXT of the gate 1, so that it extends in a parallel plane but distinct from the planes of the leaves 2 and 3 when the latter are in the closed position and the gate 4 is itself closed. This results from the positioning of the hinges or hinges 24 and from the fact that the part 24b is fixed on the inner face 410 of an upright 41 (first edge) of the door 4 which is opposite the upright 22. Similarly, when the first leaf 2 is open and the door 4 is closed (see figure 4), the door 4 is then substantially in the extension of the leaf 2, that is to say that it is in a plane parallel to that of the leaf 2 and close to it.

By adapting and mounting the hinges 24 differently, it would be possible to mount the gate 4 so that it is in the same plane as that of the leaves 2 and 3 when the latter are in the closed position and the gate 4 is itself even closed.

Advantageously, the gate 4 is provided with a return device, which constantly tends to bring it back to the closed position.

In the particular case where the gate 4 is pivotally mounted with respect to the first leaf 2, this return device can be constituted by the hinge 24 and an additional element (return spring, helical hinge, etc.) (not visible on the figures), this additional element constantly tending to bring the gate back into the closed position.

The gate 1 according to the invention comprises a first electrical device 6 for locking the gate 4 in the closed position on the second leaf 3 which is also in the closed position. This device 6 will now be described in more detail in connection with Figure 7.

The first locking device 6 comprises an electric strike 61, fixed on the outer face 321 of the upright 32 of the second leaf 3 and a main bolt 62, placed on the gate 4.

The main bolt 62 protrudes from the edge 420 of the second vertical edge 42 of the gate 4.

The main bolt 62 and the electric strike 61 are arranged facing each other, so that when the electric strike 61 is electrically activated, it occupies a so-called "locking" position, in which it receives and blocks the main bolt 62 projecting, so that the door 4 can not be opened.

Conversely, when the electric strike 61 is electrically deactivated, one of its constituent parts disappears, so that the strike then occupies a so-called "unlocking" position, in which it releases the main bolt 62, even when the latter This is salient in relation to edge 420.

In addition, the electrical activation or deactivation of the electric strike 61 is carried out by the central unit 53.

Thus, the central control unit 53 is configured to successively actuate the unlocking of the electric strike 61, then the opening of the two leaves 2 and 3, via the electric motorization device 5 or vice versa, successively the closing of the two leaves 2 and 3 via the electric motorization device 5, then the locking of the electric strike 61. This allows a user to open the two leaves to allow the passage of a vehicle. Unit 53 can be controlled by a control box or a remote control.

Advantageously, the gate 1 according to the invention also comprises a second device for locking the gate 4 in the closed position on the first leaf 2.

A first embodiment of this second locking device will now be described in conjunction with Figure 7. In this case, this second locking device is electromagnetic and bears the reference 7.

This second locking device 7 comprises an electromagnet 71 and a ferromagnetic pad 72.

Advantageously, the electromagnet 71 is arranged on the first leaf 2, more precisely on the outside face of its vertical upright 22, while the ferromagnetic pad 72 is arranged on the gate 4, preferably on the inside face of the upright 41.

The electromagnet and the ferromagnetic pad 72 are arranged opposite each other, when the door 4 is in the closed position, so that when the electromagnet 71 is activated (that is to say supplied with electricity ), it attracts the ferromagnetic slider 72 and locks the gate 4 in the closed position on said first leaf 2 and when it is not supplied with electricity, it no longer attracts this slider 72, so that it unlocks the gate 4 with respect to leaf 2. This particular arrangement also makes it possible, in the event of failure of the power supply of the motorized gate, to retain the manual opening of the gate and the possibility of an emergency exit.

In the activated position of the second locking device 7, it can be seen that the gate 4 is thus maintained in a plane parallel to the first leaf 2, so that even when this first leaf 2 is open (as represented in FIG. 4), the gate 4 remains in the extension, or more exactly in a plane parallel to that of the first leaf 2 and is integral with the latter, during the pivoting movement of the first leaf 2.

Conversely, when the device 7 is unlocked, the user can pivot the gate 4 to open it, (see figure 3).

Advantageously, the central control unit 53 is also configured to successively actuate the locking of the second electromagnetic locking device 7, then the unlocking of the first electric locking device 6 and finally the opening of the two leaves 2, 3 at the using the drive device 5. We are then in the situation shown in Figure 4.

Conversely, the central control unit 53 is also configured to successively control the closing of the two leaves 2, 3 using the motorization device 5, then the locking of the first electric locking device 6 and finally the unlocking of the second device lock 7. Thus, when the two leaves and the gate 4 have been returned to the closed position, the user can then, if he wishes, open the gate 4, by unlocking the locking device 6 using a control button thereof or by acting on the bolt 62 as will be described later.

In Figure 9, one can thus see the electromagnet 71 and the ferromagnetic shoe 72, while the door 4 is in the open position.

A second embodiment of the second device for locking the gate 4 in the closed position on the first leaf 2 will now be described in conjunction with Figures 5 and 6. It bears the general reference 8.

This second locking device 8 can be used when the gate 4 is pivotally mounted relative to the first leaf 2.

The locking device 8 comprises a fixed keeper 81, fixed to the first leaf 2 and a secondary bolt 82 arranged on the gate 4.

The fixed keeper 81 is best seen in Figure 8. It comprises an L-shaped profile, one branch of which is fixed to the second edge or upright 22 of the first leaf 2 and the second perpendicular branch of which is pierced with an opening 810.

The secondary bolt 82 is movable in translation between a so-called "locking" position, in which it protrudes out of the edge 410 of the first vertical edge 41 of the door 4 and in which it enters the opening 810 of the fixed keeper 81 ( see figure 5) and a so-called "unlocking" position, in which it is erased inside the door 4 and more precisely its upright 41 and in which it is no longer in the opening 810 so that it no longer cooperates with the fixed keeper 81.

The locked position of the secondary bolt 82 is shown in Figure 5 and the unlocked position in Figure 6.

The secondary bolt 82 is connected to a rod 45 which passes through the gate 4 and which is itself connected at its opposite end to a cam 46 driven in rotation by two handles, respectively an interior handle 47 located on the interior face 43 of the gate and an exterior handle 48 located on the exterior face 44 of the gate. These two handles are interconnected by a pin not shown in the figure and which passes through the cam 46.

The user can thus, by acting on one or other of the handles 47, 48, move the bolt 82 by sliding.

It will be noted that in this case, the hinge with a return device 24 constantly tends to return the gate 4 to the closed position and that the bolt 82 is advantageously provided with a return spring which also tends to return it to the locked position ( exit).

According to a possible alternative embodiment of the invention, the main bolt 62 is not fixed, but it is movable in translation between a so-called "locking" position, in which it projects from the edge 420 of the second edge 42 of the gate 4 and enters the electric strike 61 and a so-called "unlock" position, in which it is erased inside the gate 4 and does not cooperate with the electric strike 61.

The locking of the main bolt 62 is illustrated in Figure 5 and its unlocking in Figure 6.

It will be noted that when the main bolt 62 is in the locked position (out) and the electric strike 61 is unlocked, it is then possible to open the door 4. Conversely, even when the electric strike 61 is locked, if the main bolt 62 is operated manually by the handles 47, 48, it is possible to open the gate 4.

Advantageously and when the second locking device is the mechanical device 8, the main bolt 62 and the secondary bolt 82 can be moved together using the handles 47, 48 so that they are simultaneously in the locking position ( see arrows F1 in Figure 5) or simultaneously in the unlocked position (see arrows F2 in Figure 6).

In this case, the main bolt 62 is also actuated by the cam 46. Advantageously, the gate 1 can also be equipped with a pair of shoes 9 (see figure 10).

Each shoe 9 has a fixed part on the exterior side of the gate 1, intended to limit the travel of a leaf when it has reached its closed position.

The alternative embodiment in which the gate 4 is sliding will now be described in conjunction with Figures 11 and 12.

In this case, the hinges 24 are removed and the leaf 2 has, preferably on its outer face, a top guide rail 25 and a bottom guide rail 26. These two guide rails are perpendicular to the axis Y1-Y '1.

The upper guide rail 25 preferably extends vertically and cooperates with rotating rollers (slides) fixed to the inner face of the gate 4 in the upper part thereof.

The bottom guide rail 26 preferably extends horizontally and supports the lower part of the gate 4. The gate 4 is advantageously provided at its lower part with rotating rollers, capable of rolling in the rail 26.

The pebbles are not visible in the figures.

The gate 4 can thus slide relative to the first leaf 2 in a plane parallel to the latter, between the closed position (see FIG. 12) and the open position (see FIG. 11), as described for the previous embodiment.

The first electrical locking device 6 and the second electromagnetic locking device 7 are identical to what has been described previously.

As with the swing system described above, the gate 4 is advantageously provided with a return device, which constantly tends to bring it back to the closed position.

In the particular case of the gate 4 sliding relative to the first leaf 2, this return device can be constituted by an additional element (return spring, gravity system, etc., etc.) (not visible in the figures).
