Description

SYSTEM FOR OPENING AND CLOSING ACCESS

The present invention relates to a system for opening and closing access, including access to land. In general, the area of available land is increasingly reduced ©. However, known access opening and closing systems include mobile portals which, during their movement, occupy an important place.

In addition, since a portal must not open on the public road, there are additional constraints on the kinematics of the portals of the opening and closing access systems when the gates, in the closed position, are at near the public road.

A first known type of access opening and closing system comprises a gate rotatably mounted along a vertical axis relative to a fixed pole. Because of the quarter-circle movement of the gate, there is around the fixed post a large occupancy space corresponding to a quarter disc centered on the fixed post and whose radius is equal to the length of the gate.

A second known type of access opening and closing system comprises a gate mounted in horizontal translation along a fixed guide rail. Because of the translational movement of the gate between its open position and its closed position, only a gate whose length is less than half the width of the ground at the guide rail can be implemented. a third known type of system for opening and closing access to a field is an accordion system whose portal comprises two parts; a first portion rotatably mounted along a first vertical axis relative to a fixed pole, and a second portion rotatably mounted to the first portion along a second vertical axis. The space occupied by such a portal is less important than that of a system of the first type, but it is already at least equal to the quarter disc centered on the fixed post and whose radius equal to the length of the first · part of the portal. And to this space of occupation of the first part of portal, it is necessary to add the space of occupation of the second part. Finally, the problem of space occupation is added that the portal is divided into two parts, the choice of its design is limited.

A fourth known type of land access opening and closing system is a fan system whose gate comprises several parts (generally at least six), all mounted in rotation relative to a fixed pole along an axis. horizontal oriented in the direction of the access to the ground. If this fourth type of system does not pose a problem of occupation, it raises problems related to the technical difficulty of their implementation, to their high cost, and to the very limited choice of the design of their portal which is cut into one. significant number of parties.

The present invention aims to provide a system for opening and closing an access generating a very limited occupation of the ground during the movement of its portal, having no technical difficulty of implementation, and allowing a choice of design as important as the first two known types of access opening and closing system.

Comte illustrated in the various figures, the invention relates to a system for opening and closing an access 1 to control access to land,

The system for opening and closing an access 1 object of the present invention comprises a guide rail 2, a pole 3, a gate 4 and a synchronization system 5, 6, 7, 8, 9, 10, 11 .

The guide rail 2 is fixed and extends in a guide direction 12 defining a vertical guide plane. The system may also have a plurality of parallel guide rails 2 (as shown in FIGS. 14 and 23 to 25).

Among the possible modes of attachment, the guide rail 2 can be fixed to a wall (as illustrated in FIGS. 1 to 3) or carried by vertical uprights 13 fixed to the ground (as illustrated in FIGS. 4, 5, 9, 11, 12 and 23).

Preferably, when the part of the ground where the guide rail 2 extends has a vertical inclination in the guide direction 12, the guide rail 2 is arranged to extend in a plane of displacement which makes an angle inclination 14 with the horizontal plane so as to take account of the inclination of the ground (as illustrated in FIG. 4),

The post 3 is slidably mounted relative to the guide rail 2 between an open position and a closed position.

The post 3 can be worn only by the guide rail 2 (as shown in Figure 23) or be carried by me support wheel 15 (as shown in Figure 24), In the case where the post 3 is worn by means of a support wheel 15, this support wheel 15 is preferably mounted in rotation, in a horizontal ascending manner, on a support rail 16 which is fixed to the ground parallel to the guide direction 12,

In the case where the guide rail 2 makes an inclination angle 14 with the horizontal plane, connecting members, ensuring the connection of the post 3 to the guide rail 2 are fixed to the post 3 by being inclined relative to the horizontal plane An angle equal to the angle α 'inclined its 14. In this way, the post 3 remains oriented vertically regardless of its position (as shown in Figure 4).

In order to prevent tilting of the post 3 with respect to the guide rail 2, the post 3 is guided in translation along the guide rail 2 by a fixed anti-tilt rail and parallel to the guide direction 12 and by a antitipper element carried by the pole 3 and at least partially surrounding the anti-tip rail. The anti-tip element may have, in cross section (perpendicular to the guide direction 12), a dovetail profile corresponding to the cross section of the anti-tip rail. The antitipper element may also be formed by a cylinder (for example a ball cage) mounted in translation around the anti-tip rail. Preferably, the anti-tip rail is formed by the guide rail 2.

The translation of the post 3 on the guide rail 2 can be achieved by different means. It is thus possible to use a toothed wheel rotatably mounted on the post 3 and engaged with a rack which extends along the guide rail 2. It is also possible to use a closed belt 17, the belt 17 being fixed to the post 3 and driven in displacement by two transmission rollers, 18 whose vertical axes of rotation, are fixed and arranged at each end of the guide rail 2 (as shown in Figure 16), it is still possible to use a guide nut 19 carried by the pole 3 and engaged around a guide screw 20 which extends along the guide rail 2 (as illustrated in FIG. 25), the guide screw 20 being mounted in rotation around its longitudinal axis {gui is parallel to the guide direction 12).

The gate 4 is rotatably mounted relative to the pole 3 between an open position releasing the access and a closed position obstructing the access. Preferably, the gate 4 in the open position is parallel to the vertical guide plane. Preferably, the axis of rotation 21 of the gate 4 to the post 3 extends in a vertical direction.

The gate 4 is delimited vertically by two vertical edges 22, 23: a first vertical edge 22 which is adjacent to the post 3, and a second vertical edge 23 opposite the first vertical edge 22.

Preferably, for aesthetic reasons and in order to limit the masonry operations, the gate 4 is carried only by the post 3. It is also possible that the gate 4 is carried by a support wheel which is mounted on the gate 4 pivotably along a vertical pivot axis 24 and which is adapted to ride on the ground. Preferably, when the gate 4 is carried by a support wheel, the latter is mounted on a rolling rolling support rail 25 which extends under the gate 4 in the closed position (as shown in Figure 20). Also preferably, in order to distribute the weight of the gate 4, the support wheel is disposed near the second vertical edge 23 of the gate 4.

In order to stabilize the rotation of the gate 4 with respect to the post 3, the rotation guidance of the gate 4 is preferably made, on the one hand, by a vertical rotation shaft which is carried by the post 3 or by the gate 4, and, on the other hand, by a vertical opening of rotation which is carried out either in the gate 4 if the vertical rotation shaft is carried by the post 3, or in the post 3 if the vertical rotation shaft is worn. by the gate 4, the vertical rotation shaft being mounted in rotation in the vertical rotation opening. Preferably, the rotation guidance is achieved by two coaxial vertical rotation shafts housed in two vertical rotation apertures, the vertical rotation shafts and the vertical rotation apertures being located at both vertical ends of the post 3 and the portal 4.

The rotation of the gate 4 with respect to the post 3 can be achieved by different means. It is thus possible to use a jack 26 connecting the post 3 and the gate 4 at a distance from the axis of rotation 21 of the gate 4 (as illustrated in FIG. 21). When a jack 26 is used, it is connected to the post 3 along a first vertical axis 27 (preferably via a projecting member 28 secured to the post 3 and oriented in the guide direction 12), and to the gate 4 according to a second vertical axis 29 (preferably via an offset arm 30 which shifts the second vertical axis 29 out of the plane of the portal 4).

For aesthetic reasons and in order to hide the mechanical connections between the post 3 and the gate 4, the gate 4 may comprise, in a fixed manner, a rotational member 31 which forms a vertical extension of the post 3 (as illustrated in FIG. where the gate comprises two rotational members 31). Preferably, the outer shape of the rotational member 31 is the same as that of the post 3, at least when the gate 4 is in one of its open or closed positions (and preferably when the gate 4 is in its position). closed position).

The synchronization system 5, 6, 7, 8, 9, 10, 11 makes it possible to synchronize the rotational movement of the gate 4 with the translational movement of the post 3 so that, when the gate 4 is in the open position, the post 3 is in the open position, and when the gate 4 is in the closed position, the post 3 is in the closed position (as illustrated in FIGS. 1 and 3). Preferably, the synchronization system 5 allows the second, vertical edge 23 of the gate 4 to follow a line 32 defined by the location of the gate 4 in the closed position for the pole. 3 and portal 4 move. The support rail 25 "where it exists" is arranged along this line 32.

FIGS. 5 to 13 illustrate a first example of synchronization system 5.

The first example of synchronization system 5 comprises an activation arm 33 (as illustrated in FIG. 7). This activation arm 33 is connected to the gate 4 and comprises, in a fixed manner, a synchronization member 34 which is mounted in translation on the post 3 in a direction of horizontal synchronization and perpendicular to the guiding direction 12. that is, as the post 3 moves along the guide rail 2, the synchronizing member 34 moves relative to the post 3 in the synchronization direction 35 (perpendicular to the guide direction 12) and causes the rotation of the portal 4.

In the first example of synchronization system 5, the activation arm 33 also comprises, in a fixed manner, a drive member 36 which is slidably mounted along a fixed drive rail 37. The drive rail 37 extends in a vertical drive plane which makes an angle with the vertical guide plane. As a result, as the post 3 moves along the guide rail 2 (and thus on the surface of the vertical guide plane), the drive member 36 moves along the drive rail 37 (and thus at the surface of the vertical driving plane) and causes the synchronizing member 34 to move in the synchronization direction 35.

The first example of synchronization system 5 also comprises a horizontal motion transformation plate 38 which is integral with the post 3 and which comprises two slits 39, 40 of different orientations and non-secant. A first of these two slots 39, 40 is a synchronization slot 39 which is oriented in the synchronization direction 35 and wherein the synchronizing member 34 is slidably mounted. The second slot is used as a motion transformation slot 40 in which is slidably mounted a motion transformation member 41 carried fixedly by the activation arm 33. As a result, when the drive member 36 moves the along the drive rail 37, the motion transformation member 41 moves along the motion transformation slot 40 and causes the activation arm 33 to move relative to the motion transformation plate 38.

In the embodiment illustrated in FIG. 8, the motion transformation slot 40 is rectilinear and oriented at approximately 45.degree. To the synchronization slot 39. In the embodiment illustrated in FIG. 27, the integral of FIG. the motion transformation slot 40 is curved and its overall orientation with respect to the synchronization slot 39 is about 40 ° (in this embodiment, since all of the motion transformation slot 40 is curved, the general orientation is determined by the straight line connecting the two ends of the motion transformation slot 40).

The shape of the motion transformation slot 40 makes it possible to have a rotation speed of the variable gate 4 as a function of the position of the gate 4 for a constant translation speed of the post 3. The curvature of the motion transformation slot 40 may not be uniform throughout its length. The motion transformation slot 40 may have a curvature only in certain places, for example, only one or the other of its two ends or both ends could be bent in order to accelerate or slow down the rotation of the portal 4.

As illustrated in FIGS. 7 and 13, the connection of the activation arm 33 with the gate 4 is made by a vertical connecting finger 42 which is fixedly supported by the activation arm 33 and which is housed in a vertical connection orifice realized in the gate 4 away from the axis of rotation 21 of the gate 4 to the post 3, Thus "when the activation arm 33 moves relative to the motion transformation plate 38" the gate 4 moves around its axis of rotation 21,

This first example of synchronization system 5 is particularly simple to implement since it requires only a fixed drive rail 37 extending in a vertical drive plane which is at an angle to the vertical plane of guidance "than a horizontal motion transformation plate 38 fixed to the post 3 and carrying two slots 39, 40 of different non-secant orientations" and an activation arm 33 connected to the drive rail 37 by an organ 36 "to the horizontal motion transformation plate 38 by a synchronization member 34 and a movement transformation member 41" and to the gate 4 by a vertical connecting finger 42.

Figures 14 and 15 illustrate a second example of synchronization system 6.

The second example of synchronization system 6 is formed, on the one hand, by an alignment of fixed projections 43 which extends parallel to the guide rail 2, and on the other hand by a contact 44 which is worn. by the pole 3 and which is adapted to cooperate with this alignment. For this purpose, the contactor 44 is movably mounted relative to the pole 3 between, on the one hand, an activation position in which it is located in line with a protruding member 43 and causes the gate 4 to rotate On the other hand, a deactivation position in which it is located between two adjacent projecting members 43 and causes the rotation of the gate 4 to stop.

According to a first option, the contactor 44 is biased in its deactivation position by a return member 45 such as a spring 45. As a result, the rotation of the gate 4 is only done when the contactor 44 is in contact with a protruding member 43. It is thus possible "by adjusting the position and the length of each protruding member 43" to determine the speed of rotation of the gate 4.

According to a second option which can be associated with the first option. "The switch 44 controls" according to whether it is in the activated position or in the position, of deactivation "the displacement of a toothed wheel carried by the post 3 between a position engaged and a disengaged position with a mechanism for rotating the gate 4.

The synchronization link 9 is formed by a synchronization bar 9 which is rotatably mounted, on the one hand, at the gate 4 in a first vertical shaft 49, and, on the other hand, to the ground according to a second fixed vertical shaft 50.

FIG. 19 illustrates a sixth example of a synchronization system 10. The synchronization link 10 is formed by a fixed synchronization vertical element 51 mounted in translation and in rotation with a horizontal synchronization element 52 carried by the gate 4. The element vertical synchronization 51 is disposed, when the gate 4 is in the closed position, near the first vertical edge 22 of the gate 4, and the horizontal synchronizing element 52 is disposed along a horizontal edge of the gate 4.

FIG. 20 illustrates a seventh example of a synchronization system 11. The synchronization link 11 is formed, on the one hand, by a support rail 25 fixed to the ground and extending under the gate 4 in the closed position and, d on the other hand, by a wheel <3. 'support which is mounted rolling on the support rail 25 and is pivotally carried by the gate 4 according to a vertical axis 24 near a second vertical edge 23 of the gate 4.

Finally, the system for opening and closing an access 1 object of the present invention also comprises a movement system dm post 3 and gate 4.

This movement system can be a manual movement system. It can also be a motorized system which, preferably, can be disengageable to allow a setting. manual movement.

The motorized system may comprise only one engine adapted to directly drive the movement of the post 3 or the gate 4, the synchronization system 5, 6, 7, 8, 9, 10, 11 providing the connection between the gate 4 and the post 3. If the motor directly drives the translation of the post 3, it can be either fixed (integral with the guide rail 2) or integral with the post 3. If the motor directly drives the rotation of the gate 4, it can be either secured to the post 3, is secured to the portal 4.

The motorized system may also include two motors; a first motor adapted to directly drive the movement of the pole 3, and a second motor adapted to directly drive the movement of the gate 4, the synchronization system ensuring the synchronization of the two motors. The first motor can be fixed or integral with the post 3, and the second motor can be secured to the post 3 or the gate 4. The use of a single fixed motor is preferable because the electric supply son are also fixed . Such an engine can be used to drive the rotation of a guide screw 20 or a transmission roller 18.

The control of the access can be realized both by a single opening and closing system 1 according to the present invention, as by two opening and closing systems 1 according to the present invention.

In the case where two opening and closing systems 1 are used, the two gates 4 are arranged so that their two second vertical edges 23 are adjacent to each other. Preferably, the movements of the gates 4 and the posts 3 of the two systems are synchronized. Typically, the two gates 4 rotate in opposite directions while the poles 3 move in one direction.

As illustrated in FIG. 26, the occupation of the ground during the displacement of the gate 4 corresponds substantially to a square whose two perpendicular sides are defined on the one hand by the gate 4 in the closed position and on the other. part "through the gate in the open position 4 Neck through the guide rail 2) * to us space 53 which is complementary to the quarter disc whose radius is equal to the length of the gate and whose center is at the corner diagonally opposite to the corner located at the intersection of the two aforementioned sides.
