Description

Description: TECHNICAL FIELD The present invention relates to a power control device for opening and closing an inlet. More specifically, it has two pivotal gates and is mounted along the vertical pivot axis of the gates for actuating each gate and is housed in the upper vertical side cavity element of the gate. Has a "tubular" electric motor, the motor's stator interlocks with the upper pivot of the gate, while its rotor is rotationally coupled to the gate element via a reducer for outdoor entrances. The present invention relates to a device, but is not limited to this.

A powered device of this kind for an entrance with two gates has already been described in French Patent No. 2450334.
The main advantage of this type of power plant is that it is completely housed in the element of the inlet it needs to operate, especially
It is to be integrally housed inside a side frame having a tubular structure of two gates.

In this known device, the stop control of each motor at the end of the corresponding gate stroke in the direction of opening and closing is ensured by the torque controller means cooperating with the electrical contacts. In addition, at the beginning or end of the opening of the entrance,
Electromagnetic barber machines intervene to keep the gates from moving relative to the ground and / or relative to each other.

Barber means of this kind are located outside the pivot axis and require electrical cables to be routed through the gate frame and other elements in order to power it, which complicates the construction of the device. Inevitably, it is a costly and cumbersome means to use, especially when a manually operated entrance is converted into an automatic entrance.

The present invention, at the end of the opening or closing process, simplifies retrofitting when modifying a manual inlet, increases reliability, safety, economy, and allows for quick installation. Eliminating these inconveniences by providing a complete motorized control system in which the pivotal drive function of each gate is ensured by the same mechanism in two senses: stop and barge at end position Is what you are trying to do.

Therefore, the invention is basically based on a power control for opening and closing an entrance of the type already mentioned, in which the gate or the drive shaft of each gate has a "cam" -like means whose axis coincides with the pivoting vertical axis of the gate. Is connected to the gate element via
This "cam" -like means ensures, on the one hand, a rotary connection of the drive shaft and the gate when the gate pivots freely about said axis, and on the other hand, at the end of its travel, A powered control device for opening and closing an entrance which converts the rotational movement of a drive shaft into a vertical translational movement of the relevant element of the gate when the pivoting is hindered by barbing of one or two gates It is a thing.

The "cam" like coupling means between the drive shaft and the element of the gate is, in the first embodiment of the invention, partly mounted rotationally on a horizontal axis carried by the drive shaft. At least one time, and another,
It is constituted by at least one sloping double-sloping surface interlocking with said elements of the gate and forming an inverted "V" shape, each roller or each roller cooperating with a corresponding double-sloping surface. , When the gate is blocked from pivoting, lift the gate within a limited range. For this reason, when the gate pivots freely, the roller is an inverted "V" formed by the double inclined surface.
When placed at the upper end of the shape and when the drive shaft rotates, there will always be a corresponding amount of rotation of the ramp and thus of the gate. Conversely, when the gate is blocked from pivoting, no matter which direction the drive shaft rotates, "up" of the inclined surface against which the rollers are pressed occurs, and thus the gate is a kind of spiral connection. Will be lifted.

As a result, barbing at the terminal position of the gate hinders the pivoting of the gate when it is lifted, but is mechanically done by a simple stop that can be overcome in one direction of the gate. You can When the motor is moved, the rotational movement of the drive shaft is converted into the first lifting of the gate,
As a result, the gate will not come into contact with the barb mechanism stop. For the second time, the rotary movement of the drive shaft continues, but the gate is given a rotary movement in the opening or closing direction. After crossing the stop, the gate “falls” back into the “low” position, and in this embodiment all rotational movements take place. At the end of the rotation, i.e. when it reaches the fully open or closed position, the gate meets the other stop and rises again and finally falls into this stop again.

In this case, the device also advantageously has electrical contacts at the end of the stroke, which contacts are actuated by the elements of the gate after it has been lifted to a predetermined height. Stop the motor arranged as described above. In this way, the stopping of the motor, which takes place when the gate has reached the end position, is simply to place a buffer on the gate track, the height of which is greater than the predetermined height mentioned above. Therefore, it is automatically controlled. This cushion acts as an obstacle to the gate and when it encounters it lifts the gate to the height at which the contacts are activated at the end of its travel. With a "reversible" geared motor in place, the gate can automatically return to its low position after the motor is turned off.

The gravity of the gate ensures a constant minimum pressure on the double ramps above the corresponding rollers. In order to obtain the desired drive torque and also to be able to adjust the value of this torque at any time, spring means are additionally provided which generate a complementary force for pressing the double-sloping surface onto the rollers. It can be a mechanical spring, in particular helical and concentric with the drive shaft, or it can be a pneumatic spring, which also forms a damper. In the latter case,
The upper end of the pneumatic spring, which is concentric with the drive shaft, is connected to said shaft and its lower end, which is connected to the pipe of the vertical axis, works in conjunction with a part having a double bevel.

In the embodiment defined above, the rotation of the gate in the "low" position can be tedious if the gate is at risk of encountering stones or other obstacles on the ground. This kind of accidental inconvenience can be avoided in the second embodiment. In this embodiment, the "cam" -like coupling means between the drive shaft and the element of the gate is due in part to at least one roller mounted on a horizontal axis carried by the drive shaft, and For one, it is constituted by at least one double sloping surface which interlocks with the elements of the gate and forms an inverted "V" shape, the sloping surface or each sloping surface facing upwards from the bottom of the gate. It is applied under the roller or one of the rollers by spring means which exerts a vertical force above the gravity on said element of the gate.

Therefore, when the gate pivots freely, it is lifted and held in that position by the spring means in the "high" position, and the roller, or each roller, has its tip or It will be at the lowest point of the corresponding double slope of the "V" shape. Conversely, when the gate encounters an obstacle that impedes pivoting, the roller has a tendency to "climb" over the slope, so that the sloped trailing gate therefore resists the action of the spring means. Will go down. For this reason, the gate keeps being lifted during all its rotations, and even if there is an accidental obstacle on the ground, it will pass above it and eventually reach the stop of the barbing mechanism. Is automatically lowered by the relative movement of the roller and the inclined surface.
Actuating the device reverses the effect obtained from the stop position above the stop. That is, the rotation of the drive shaft starts, and the gate is lifted by the action of the spring means, so that the gate that has escaped the stop stays in the "high" position and begins the rotational movement. Will be able to.

In this second embodiment, the "cam" -shaped coupling means are further provided with "V" s on either side of each double-sloping surface or each double-sloping surface, which advantageously forms a "V" -shape. It has two secondary parts that are not deeper than the "-" shaped main part and are upwardly concave separated from the main part by the mouth. This specially contoured cam allows the roller to "climb" along one of the ramps and eventually overhang the mouth at the top of the ramp to create one of the concave secondary parts. "Fall again" inside. Thereby, the contours of the rollers and the cams are fixed relative to one another in a certain relative position, while the gate is kept in the "low" position. Therefore, in the open or closed position, a stop and barbing is ensured (in cooperation with the stop). As a result, the gate is securely held in the bartack stop even in the wind.

In each case, the one or more double bevels have a central passage through which the drive shaft traverses and can be formed on a part axially and rotationally connected to the said element of the gate. The part with the ramp can be moved directly with the element of the gate, for example a frame, or it can be rotationally connected to this element via a torque limiter.

In such a construction, all of the components of the device are grouped together inside a gate, more specifically in a side frame located beside the pivot under the upper pivot. . In order for this device to work,
It will be clear that the upper and lower pivots of the gate need to be fitted to allow vertical translation of a few centimeters of travel, thereby allowing the gate to be lifted.

In this way, all the components are put together, and the rotary drive,
By securely performing various functions such as end of stroke and bar tacking with a single mechanism, in the power control device according to the present invention, the electromagnetic bar tacking means placed separately or other independent bar tacking device Etc. are all eliminated, and thus it is no longer necessary to pass electrical cables through the elements of the gate.

Further, the vertical movement of the gate solves the problem of being blocked on the ground by the action of freezing in winter or the problem of being blocked by a small obstacle on the orbit of the gate.

In addition, if you encounter an unexpectedly large obstacle in the process of rotating the gate, the rotation will automatically stop,
Any damage is avoided and the desired safety is completely ensured when the obstacle is a person or a vehicle.

Since the number of parts required for installation is much smaller than existing equipment, the reliability of the motorized inlet is considerably higher and the simplification results in a lower total set cost.

Finally, by bringing together all the components needed for powering, the manual inlet can be easily, quickly and economically converted into an automatic inlet. On the contrary, the entrance provided with the motorized control device according to the invention can be reworked in particular to stop the barb mechanism, so that it can also be easily operated manually, especially when the power is turned off.

In any event, the invention will be better understood by the following description, given by way of example with reference to the accompanying schematic drawings which show two embodiments of a power control device for opening and closing an inlet. However, it goes without saying that these examples do not limit the scope of the present invention.

The entrance shown in FIG. 1 has two gates 1 and 2, which have, for example, an upper pivot 3 and a lower pivot 4 which are fixed in a pillar 5 by a stiffening process. Mounted to pivot about a vertical axis. Each gate 1 or 2 consists of a rectangular skeleton mainly formed by two tubular side frames 6, 7 connected between them by at least one upper horizontal element 8 and at least one lower horizontal element 9. Have The garment inside the gates 1 and 2 can be performed using the lattice 10 and / or the blind plate 11 by various known arrangement methods. In this example, each gate 1 or 2 is in the position of the first terminal defined by a common central stop 12 in the closed position and in the fully open position (generally indicated by the dashed line). Second) defined by respective stops 13, 14 on the sides
It pivots about 90 ° between the positions of its terminals. Stop 12,1
3, 14 are fixed to the ground.

Since the two gates 1 and 2 have the same power unit, only one of these gates, for example, a device related to the gate 1 will be described below. More specifically, the first embodiment will be described first with reference to FIGS.

Powering the opening and closing of the gate 1 is ensured by a "tubular" geared electric motor 15 which rotates in two directions along a vertical pivot 16 of the gate 1. The geared motor 15 is housed under the upper pivot 3 in the upper part of the side frame 6 of the gate, and the stator of the motor is fixed to the upper pivot 3.

The side frame 6 of the gate 1 pivots about a vertical axis 16 via at least two guide rings 17, 18 that surround the stator of the geared motor 15 and also this axis 16
It is attached so that it slides alongside the. By being attached in this manner, the entire gate 1 can perform a complementary movement called vertical translation movement. The lower pivot 4 is made to allow this translational movement.

The output shaft 19 of the geared motor 15 forming the drive shaft for rotation of the gate 1 extends below the geared motor 15 along the vertical shaft 16. Drive shaft 19
Are diametrically traversed by a horizontal axis 20 to which two opposite frustoconical outer faces 2
1, 22 are mounted for rotation.

At the height of the rollers 21 and 22 inside the tubular side frame 6, a cam-shaped component 23 interlocking with the frame 6 is attached. This component 23 is a drive shaft 1
9 has a central passage 24 traversed and is provided with two diametrically facing double doubly inclined surfaces 25, 26. Each double beveled surface 25 or 26 has one ascending portion and one descending portion which join at the upper end to form an inverted "V" shape, with the sloping rolling surface facing downwards. ing. The two rollers 21 and 22 cooperate with the double inclined surfaces 25 and 26, respectively, and each double inclined surface is supported by a roller which can roll along the double inclined surface.

The lower end of the drive shaft 19 forms a bearing, in which
The upper end of a pneumatic spring 28, which is also arranged alongside the vertical axis 16 and is arranged inside the side frame 6, is connected via a stop pin 27. The lower end of the rod 29 of the pneumatic spring 28 terminates in an end fitting 30, which is connected via a small horizontal shaft 31 to the gas spring 2.
It is connected to the lower end of a vertical axis tube 32 which surrounds 8.
The upper end of the tube 32 is adapted to interlock with the cam-forming part 23 and thus with the frame 6. This pneumatic spring 28 acts on the part 23 from above through the tube 32 and acts on the double inclined surfaces 25, 26 to the respective rollers 21, 2.
2 and thereby try to pull the frame 6 downwards.

For this reason, the original gravity of the gate and the complementary force generated by the gas spring 28, especially the two rollers 21,
22 is sought to be maintained in the area of the "V" -shaped tip formed by the double beveled surfaces 25, 26 as shown in detail in FIG. For this reason, the gate 1 occupies the usual low position as also shown in FIG. When the gate 1 occupies this position and is not prevented from pivoting by an obstacle, the torque of rotation given by the geared motor 15 with the drive shaft 19 is the roller holder shaft 20, roller 21. , 22,
And is transmitted to the gate 1 via a cam-forming component 23, which causes the gate to pivot about an axis 16 in the direction of opening or closing.

On the contrary, when an obstacle intentionally or unintentionally placed on the passageway of the gate 1 interferes with the pivotal movement of the gate 1, the geared motor 15 is actuated, which causes the drive shaft 19 to rotate. As shown in Figure 4, the roller 2
"Rise" of the inclined surfaces 25, 26 against which the 1, 22 are pressed occurs. As a result, the component 23 forming the cam
But with the side frame 6 and the gate 1 set, the arrow 3
It is shifted upwards according to 3.

The geared motor 15 has an end-of-stroke electrification contact 34 incorporated therein, which contacts the gate 1 when lifted by a predetermined height h, for example 3 cm. , Operated by the upper guide ring 17 of the frame 6. Ring 17
At the moment when the contact actuates the contact 34, the geared motor 15 is de-energized, and the drive shaft 19 causes the torque of the rotation, which is converted into the lifting force by the component 23, into the roller holder. No more transmitting via shaft 20.

From this moment on, the gate 1 automatically returns to its lower position and, due to the reversibility of the geared motor 15, stops pivoting about the vertical axis 16. The gas spring 28 is also useful for lowering the gate 1, but with this lowering, the two rollers 21, 22 are also formed by the double inclined surfaces 25 and 26, and the tip of the "V" is formed. Return to the area.

On the contrary, if the gate 1 cannot be raised more than the predetermined height h, the ring 1
7 does not activate the electrical contacts 34 at the end of the stroke. This is the case when the gate 1 encounters an obstacle on its passage whose height is less than h. In such a case, even after the gate 1 is lifted by a height equal to the height of the obstacle, the geared motor 15 continues to give the rotating torque to the gate 1 and the gate overcomes the obstacle. , Then it can descend to the lower position again and continue the pivoting movement.

Combining the various individual sequences described above, for example, considering the movement of the gate 1 opening starting from the gate chain position of the gate stopped on the central stop 12, the actuation of the entrance set is Is done like.

For example, when the geared motor 15 operated by a push button or a remote-controlled portable signal transmitter is operated, first, the "bare-off" of the gate 1 occurs, the gate is slightly lifted, and the center stop I'm not going to have to worry about 12. Therefore, the gate 1 starts to rotate and the stop 1
After climbing over 2, it returns to its lower position and normally remains in this position during its pivoting movement around the vertical axis 16 until it approaches the lateral stop 13.

5 to 8 are very diagrammatic representations of what happens when the gate 1 reaches the side stop 13.

The stopper 13 has a rising portion 36 and a cushioning portion 37 on a step 35 fixed on the ground, and these have a recess 3
It is divided by 8. The riser 36 has a height a with respect to the horizontal reference plane that is less than the gate lift height h for activating the electrical contacts at the end of the stroke. On the contrary, the buffer portion 37 has a height b larger than the lifting height h described above.

As shown in FIG. 5, when the stopper 13 is reached, the lower part of the gate 1 first hits the outer surface of the rising portion 36. The gate 1 is prevented from pivoting by an obstacle formed by this part 36 of the stop 13 and causes the first vertical movement to reach the height a.
Can only be lifted.

After being lifted in this way, the gate 1 is driven to rotate again, and completely overtakes the rising portion 36 as shown in FIG. 6, and then its width corresponds approximately to the thickness of the gate 1. It "falls" over the recess 38.

The geared motor continues to operate and attempts to maintain the pivoting of the gate 1. Then, the gate encounters a new obstacle composed of the buffer 37. Then, the gate 1 is lifted up again, and lightly hits the side surface of the buffer portion 37, as shown in FIG. When the gate 1 is displaced upward by the height h, the contact at the end of the stroke is activated, and immediately commands the stop of the geared motor.

Then, the gate 1 falls into the recess 38 again, and finally becomes immobile between the rising portion 36 and the buffer portion 37 (eighth embodiment).
See figure).

When the gate 1 is operated in the closing direction, the gate is first lifted up and over the rising portion 36 of the stopper 13,
It then "falls" again at the tip of the riser 36 and pivots until it reaches the central stop 12. The central stop has the same function as the side stop 13.

These stop rises 36 are removable so that the inlet can be operated even if the geared motor is temporarily turned off.

Of course, a similar stop could be used regardless of the angle of pivoting of the doors 1,2.

It will also be appreciated that unintentionally placed obstacles in the passageway of the gate 1 or 2 also perform a similar function as a stop. If the height of the obstacle is small, such as gravel, and smaller than the value h (against the reference plane), the gate will be lifted slightly and then the obstacle will be overcome. On the contrary, in the place where there are larger obstacles like rocks, the lift of the gate also becomes large and the movement of the gate is stopped.

The pneumatic spring 28 reliably lowers the gate 1 or 2 each time the gate passes over the obstacle, if an obstacle is intentionally (stopped) or unintentionally placed on the passageway of the gate. Play a role. This spring 2
8 also has the effect of counteracting the effect that the wind may have on the rotation of the gate 1 or 2, and also against another person's intentionally lifting the gate.

Instead of pneumatic spring 28, a helical spring or other mechanical spring that performs the same function can be used.

9 to 16 relate to another embodiment. In these figures, elements corresponding to those described above are given the same reference numerals.

Now, FIG. 9 newly shows a part of the gate 1, and the gate has a tubular side frame 6 on the joint side thereof.
And a horizontal element 8 is joined to its upper end. The gate 1 is mounted so as to pivot about a vertical axis 16 via a side pivot. FIG. 9 shows only the upper pivot 3 which is fixed in the column-like tight part 5.

Electric motor 15 with a "tubular" gear that rotates in two directions
Are arranged along the vertical pivot 16 of the gate 1.
The geared electric motor 15 is housed in the upper part of the frame 6 below the upper pivot 3 and the stator of the motor is adapted to interlock with this pivot.

The frame 6 of the gate 1 can slide vertically along the shaft 16 due to the guide rings 17, 18 which surround the stator of the geared motor 15. Such a slidable mounting allows the entire gate 1 to undergo a limited vertical translation movement, and thus can be lifted or lowered. The lower pivot (not shown) is constructed so as not to interfere with this vertical movement.

The output shaft 19 of the geared motor 15 constitutes a rotary drive shaft of the gate 1 and extends below the geared motor 15 along with the vertical shaft 16. Drive shaft 1
9 supports a horizontal shaft 20, on which rollers 21 are rotatably mounted. The rollers can have a truncated cone shape.

Mounted inside the tubular side frame 6 is a part 23 forming a cam, which part has a central passage 24 in which the drive shaft 19 rests. This part 23 is axially connected to the frame 6 as indicated at 39 and also rotationally connected to the frame 6 via a torque controller 40.

The part 23 is provided with a cavity at the level of the roller 21 to form a cam, the lower lip of which mainly forms a double bevel 25. This double slope has the same average slope α, but opposite slopes, and is composed of two rolling slopes, one is "up" and the other is "down", and has a "V" shape. (See also Figure 10). The contour of this cam has a "V" shaped double slope 2
On both sides of 5, there are two secondary parts 41 which are curved and whose concave surface faces upwards. The height of these portions 41 is less than the height of the "V" shaped body and is separated from the body by a mouth 42.

As shown in FIG. 10, the cam also has a "V
On the double-slope 25 in the shape of a letter, there is a generally triangular downward facing mouth 43, the edge of which has approximately the same slope α as the double slope 25.

Although FIG. 10 is a developed view of the contour of the cam, it will be easily understood that the portion that looks almost straight in this figure is actually spiral.

The drive shaft 19 has a downwardly extending extension 44 to which a disc 45 is connected. A helical spring 2 which is compression operated and concentric with the drive shaft 19.
8 has a lower end supported by a disk 45, while an upper end thereof forms a cam via a ring 46.
It is supported under three.

The spring 28 exerts on the part 23 a vertical force F from bottom to top, which force is due to the axial connection (at 39) between the part 23 and the frame 6 to the frame 6 of the gate 1. Be transmitted to. The force F of the spring 28 is the gate 1
Is selected to be larger than the gravity P of. Therefore, the spring 28 strongly hits one of the double inclined surfaces 25 or one of the contoured portions 41 of the cam under the roller 21, and the other one tries to lift the entire gate 1. Will have two effects.

11 to 16 show a very schematic representation of the function of the entire entrance, but in order for the entire entrance to function, it is additionally fixed to the ground and a closing stop cooperating with the lower part of the gate 1. Use of 12 and release stop 13 is required. The closing stopper 12 is provided on the step 47 with a buffer portion 48 and a rising portion 49 separated by a recess 50. Opening stopper 13
Similarly, similarly, the rising portion 36 and the cushioning portion 37 separated by the recess 38 are provided.

In FIG. 11, the entrance is initially closed and the gate 1 is
In the lower position, the stop recess 50 of the closure stop 12
It is supposed to be dormant in. This position is maintained by introducing the roller 21 into one of the concave secondary portions 41 of the contour of the cam.

To operate the opening, the geared motor 15 is moved in the direction in which the drive shaft 19 rotates in the direction of arrow 51. Although the gate 1 is prevented from rotating by the rising portion 49, the roller 21 is pulled out from the concave secondary portion 41, gets over the adjacent opening portion 42, and doubles in a “V” shape. Start spinning on the "descent" part of the slope. In practice, the roller 21 remains at a constant level in the relative movement thus generated, and under the action of the spring,
It is the gate that is lifted as shown by the arrow in FIG. It can be seen that the gate 1 slides along with the buffer 48 during the lifting process.

The lifting movement of the gate 1 is continued until the roller 21 reaches the lowest point of the "V" -shaped double inclined surface. At this time, as shown in FIG. 13, the lip under the gate 1 is located higher than the rising portion 49 of the closing stopper 12.

The drive shaft 19 continues to rotate in the direction of the arrow 51, and thereafter the gate 1 becomes free to pivot, so that the gate 1 as shown by the arrow 53 in FIG. The pivoting movement in the opening direction actually begins. During the whole period of this opening movement, the gate 1 is "high"
It stays in position, pivots at the same speed as the drive shaft 19, and the roller 21 remains at the lowest point of the double ramp 25.

At the end of the opening movement, the gate 1 freely crosses over the riser 36 and then reaches the closing stop 13, first hitting the buffer 37, which prevents the gate from continuing to rotate. However, the rotational movement of the drive shaft 19 in the direction of the arrow 51 is still uninterrupted, so that the roller 21
The "up" portion of the "V" -shaped double inclined surface 25 comes to rotate. In reality, the roller 21 stays at a constant level, slides along the buffer portion 37 according to the arrow 54 in FIG. 15, and descends at the gate 1.

As this operation continues, the lip under the gate 1 descends into the recess 38 and reaches a position lower than the rising portion 36. As a result, bargaining is started. "Roll" 21 "Rise"
At the end of the, the roller "overfalls" one of the mouths 42 and "falls" again into the secondary part 41 opposite the previously separated concave secondary part (see FIG. 16). . Next, the gate 1
It will stop at the open position and be barbed. The geared motor 15 automatically stops at a certain timing, and the gate 1
Shaft 19 and parts 2 even after they have already been blocked
The rotation of 3 is made possible by the torque controller 40.

It will be appreciated that the exact opposite process occurs when the entrance is closed. In this case, the two stops 12,
Only the roles of 13 will be exchanged, and the gate will reach the closed position while maintaining the "high" position.

At the start of the opening or closing movement, if the gate 1 cannot be lifted only by the action of the spring 28 due to, for example, freezing, the roller 21 cooperates with the mouth portion 43 of the contour of the cam, and It is necessary to be careful to actively attempt "lift".

Instead of one roller 21, it is also possible to deploy two diametrically opposed rollers, each cooperating with the two contours of the cam. Also, the torque controller 40 associated with the timing function can be eliminated and instead replaced with an end-of-stroke electrical contact actuated by the gate 1 reaching the open or closed position.
