Description

Pillar for automatically opening or closing a door] and carried including such a pillar

The present invention relates to a pillar for automatically opening and closing a door leaf! and a gate having at least one leaf, including such a piiier.

Portals are known comprising one or more hinged leaves relative to laterally placed sleepers and defining between them the useful space of passage of the gate.

These portals of the prior art, which are generally not automated, however, do not have the necessary amenities to their engine. They are not intended to receive a housing likely to receive the support means of a power unit, nor the control boxes of this engine.

M is then necessary to mount the mechanisms to drive in rotation one or two wings hinged externally to the gate.

These gate operator mechanisms may comprise a motor unit connected to a jack whose end of the rod is secured to the corresponding leaf. These mechanisms external to the gate are not aesthetic and also represent a potential source of danger for children who may be brought to put their hands on the rod of the cylinder during its operation. Furthermore, these mechanisms do not allow to have an opening of the leaf inward or outward between 0 ° and 180 °.

Figure 1 shows a partial view of an automated portal of the prior art comprising a flap 1 hinged. The movement mechanism 2 of the wing 1 is buried in the ground 3 at the corresponding frame 4 which is for example a post sealed in the ground 3. This mechanism 2 represents a solution to automate the gate without changing the aesthetic .

The pivot axis 5 of the hinged leaf is placed in a plane P closing the gate passing here through the pole 4 and the ends of the leaf 1. The leaf 1 is connected in its upper part and its lower part by pivots 6, 7 to solidarity hinges of the post 4.

The displacement mechanism 2 comprises a bar 8 mounted below the horizontal cross member 9 of the lower wing 1. This bar 8 is also secured to a connecting rod 10 adapted to describe under the impetus of a motor a rotational movement. When this rod 10 is actuated in rotation, it drives through the bar 8 the rotation of the wing 1, and the opening or closing of the gate.

However, the installation of such a portal automation system requires digging in the ground a housing 11 capable of receiving not only the movement mechanism 2 of the wing 1 but also the integrated power cabinet (not shown) .

Such a system is subject to bad weather that may eventually seep into the engine block and seriously damage the movement mechanism 2 of the wing 1. In addition, this device of the prior art only allows to have an opening of the wing 1 inwards or outwards up to 90 °. Gold the size of the wings thus positioned at 90 ° is very important and limits the space required to maneuver a motorized vehicle for example in a parking area.

It would therefore be advantageous to have gates whose opening angle inwards or outwards can be between 0 ° and 180 °.

This need is, indeed, very important not only for manufacturers, but also for individuals.

The object of the present invention is therefore to provide a pillar for automatically opening and closing a gate leaf, simple in its design and its operating mode, economic, and to open and close the leaf from an angle between 0 ° and 180 ° in order to place the leaf at the maximum.

Another object of the present invention is to provide a gate comprising one or more leaves actuated by such pillars. For this purpose, the invention relates to a pillar for automatically opening and closing a gate leaf, this pillar having an axis of rotation of the leaf, this axis of rotation being spaced from said pillar so that the leaf can be operated from an angle between 0 ° and 180 ° relative to the closing plane of said gate. According to the invention,

the pillar comprises a motorized drive member for the leaf around the axis of rotation,

the drive member comprises a motor element housed in the pillar, this motor element having an output shaft, and a torque transmission element of the output shaft to a hinge so as to drive this hinge in rotation, and

- The hinge is placed so as to be positioned between the upper and lower ends of the vantai] to be supported by this pillar to cooperate with a pivot fixed on the leaf. The term "gate closure plan" means the plane containing the ends of the gate leaf (s), each leaf being able to present between its ends of non-planar parts, when the gate is closed to prevent the passage of a person, a machine or a motor vehicle or other.

In different particular embodiments of this pillar, each having its particular advantages and susceptible to many possible technical combinations:

the pillar comprises at least one upper fixed hinge and one lower fixed hinge defining the axis of rotation of the leaf, said hinge able to be rotated by the drive member being interposed between the upper and lower hinges; the axis of rotation of the leaf is defined by a fixed hinge and said hinge able to be rotated by the drive member,

the torque transmission element is a chain or a belt,

- The pillar comprising an electronic control unit, this unit comprises a controller of the motor element and / or a control element and supply of a locking member on the floor of the leaf.

Advantageously, it comprises at its upper end a light indicating the opening or closing of the leaf by the motorized drive member. This indicator light may include its own power supply source such as a battery integrated in the pillar or a solar panel placed laterally to the pillar. Alternatively, this indicator light is connected to said electronic control unit for its power supply.

The invention also relates to a gate comprising at least one leaf supported by a vertical support. According to the invention, this vertical support is a pillar as described above.

Preferably, the leaf being connected by pivots to the pillar, these pivots comprise means for adjusting the position of the leaf. These means may allow adjustment of either the vertical position of the leaf or the spacing between the leaf and the corresponding pillar, or both. These means for adjusting the position of the leaf are taken up by the hinge adapted to be rotated by the drive member.

Thus, purely illustrative, for the adjustment of the vertical position of the leaf, the hinge adapted to be rotated by the drive member may comprise in its upper part a set of bores threaded or not arranged along. a vertical axis, these holes being intended to allow the adjustment of the fixing position of a horizontal cylindrical hollow element by means of a fastener such as a screw. This hollow element which comprises a recess of vertical axis allowing its positioning along said upper portion of the hinge is intended to cooperate with a pivot of the leaf. The adjustment of the spacing may for example be obtained in that the cylindrical element comprises two cylindrical parts mounted on either side of a screw for adjusting the length of this cylindrical element. Each of these parts comprises an orifice placed opposite a longitudinal hollow of the screw, for example a groove, this orifice being intended to receive the rod of a fastener element, such as a screw, of which the end cooperates with said hollow to secure said portion to the screw on which it is mounted.

Preferably, the leaf supported by the pillar has a locking member on the floor of the leaf. This leaf has an integrated link control and supply of this locking member which is intended to cooperate with the electronic control unit of the pillar.

The invention finally relates to a fence comprising an access gate comprising at least one leaf. According to the invention, this access portal is a portal as described above.

Preferably, this gate comprises two leaves, each of these leaves being supported by a pillar as described above. Both leaves can be opened and closed automatically. The invention will be described in more detail with reference to the accompanying drawings in which: - Figure 1 is a partial view of a portal of the prior art, in profile (Fig, 1a) and in plan view (Fig 1 b);

- Figure 2 schematically shows a portal according to one embodiment of the invention; the right part of this portal shows an exploded view of the left part of the portal;

FIG. 3 is an exploded view of the motorized drive member of a pillar of FIG. 2;

Figure 2 shows a gate comprising two leaves 12, 13 hinged according to a particular embodiment of the invention. Each leaf 12, 13 comprises a metal frame obtained by assembling two horizontal sections to vertical uprights, which are fixed for example by welding to the horizontal sections. Alternatively, each leaf can be full instead of openwork. It may also comprise a non-planar portion secured to a flat metal frame consisting of two horizontal crosspieces and two vertical uprights.

This portal comprises two pillars 14, 15 each supporting a leaf 12, 13. The right part 16 of the portal is an exploded view of the left part 17 of the portal to facilitate the understanding of the invention. Each pillar 14, 15 can automatically open and close the door leaf 12, 13 it supports. The pillar 14, 15 comprises for this purpose an axis of rotation 18 of the leaf 12 which is offset with respect to this pillar 14. The leaf 12 is thus pivotable about this axis of rotation 18 and can be maneuvered by an angle between 0 ° and 180 ° with respect to the closing plane of said gate.

The left part 17 of the portai! in Figure 2 is in the closing plane of the portal.

This axis of rotation 18 of the leaf 12 is defined here by an upper fixed hinge 19 and a lower fixed hinge 32 receiving pivots of the leaf 12 pivoting. All of these elements are identical on the right part 16 of the portal. Each of the pillars 14, 15 may be made of plastic, concrete, plaster or from metal sheets. When it is a plastic post, concrete or metal, this post is preferably sealed to the ground. Each pillar 14, 15 comprises a motorized drive member of the leaf around this axis of rotation 18. This drive member is integrated in said pillar 14, 15. Preferably, each of the pillars 14, 15 comprises a housing 32 for receiving a support 26 of this drive member. The support 26 can be fixed conventionally inside this housing 32. This drive member comprises a motor element 20 housed in the pillar 14, 15, this motor element 20 having an output shaft 21. This motor element 20 is, for example, a geared motor.

Figure 3 shows an exploded view of this drive member of the leaf. The drive member comprises a torque transmission member 22 of this output shaft 21 to a hinge 23 so as to rotate this hinge 22. This torque transmission member 22 is a chain, and even better a chain tripie. Alternatively, it could be a strap.

The output shaft 21 of the motor element 20 is connected to a pinion 24 and the hinge is also integral with another pinion 25 of larger diameter. For purely illustrative purposes, the diameter of the pinion integral with the hinge is equal to or greater than that of the pinion connected to the output shaft 21 of the motor

20.

The pillar 14, 15 preferably comprises a projection receiving the hinge 23 and at least a portion of the torque transmission element 22, a portion of this hinge being external to the pillar 14, 15. This projection may take the form a box or cover 27 forming an extension of the pillar 14, 15.

The hinge 23 adapted to be rotated by the motorized drive member is positioned to be positioned between the upper and lower ends of the vantaii supported by the pillar. It is preferable interposed between the upper hinge 19 and the lower hinge 32 defining the axis of rotation 18.

The hinge 23 and motorized can cooperate with a pivot fixed on the leaf to rotate this leaf 12, 13 and open or close the gate.

This pivot is here an ear 28 having two projecting plates coming from both sides of the amount of the leaf.

The pillar 14, 15 further comprises a housing for receiving an electronic control unit (not shown) intended to control the opening and closing of the leaf 12, 13 by actuating the motor element 20.

Each pillar 14, 15 advantageously comprises at least one hatch allowing access to an operator either to the electronic control unit, or to the motorized drive member of said leaf.

The electronic control unit advantageously comprises a connection to a power supply source external to the pillar 14, 15 which is for example located in a cabinet remote from the gate. Alternatively, this power supply cabinet of the portal could be integrated into the pillar 14, 15 corresponding. This connection is an RJ 45 power cable for example. The electronic control unit also comprises a transceiver adapted to receive a control signal for actuating the motor element for a predetermined period of time. The control signal may come, for example, from a remote control transmitter operated by a user. The control unit preferably comprises a controller of the motor element 20 for controlling the torque of this motor element and / or its speed of rotation. This controller makes it possible to limit the dynamic force at the impact at the end of the leaf 12, 13 and to prevent any crash accident.

It may also include a control element and supply of a locking member to the self of said leaf. The vantaii 12, 13 supported by said pillar 14, 15 may in fact have a locking member on the ground 29. A control link and integrated power supply in the frame of the leaf 12, 13 allows to feed and control this organ This link, which is here an RJ 45 type connection, is connected at one of its ends to an input / output plug of the ground locking member 29 and at its other end to said element of locking. control and power supply. This connection can, for example, be integrated into the horizontal profile! lower vantaii 12, 13 and back in the vertical post bearing the leaf pivots. The electronic control unit is, in fact, advantageously arranged in an elevated portion of the pillar 14, 15 to prevent a possible failure in bad weather.

This locking member 29 has a frame comprising a motor driving vertically an arm 30 between a first rest position and a second so-called locking position of the leaf in which the arm 30 cooperates with a housing 31 fixed to the ground or in the ground . Two end-of-stroke elements make it possible to define the first and second positions of the arm 30. This arm 30 is for example a worm.
