EP2690242B1 - Arm actuator for door leaf and method for mounting such an actuator - Google Patents

Description

The invention relates to an actuator arm for motorizing the movement of a leaf, such as a gate, a door or a flap. The invention also relates to a method of mounting such an actuator within an installation comprising a fixed structure and a leaf hinged to this structure.

To maneuver a leaf, it is known to use an arm actuator which generally comprises an electric motor rotating a first end of a first motor arm, about a first axis, this motor arm causing rotation of a second leaf arm connected to a second end of the motor arm by a pivot connection and, on the other side, to the leaf by a second pivot link.

When mounting or installing such an actuator, it is known that the operator must respect a certain "break" angle of the articulated structure formed by the two arms, in order to limit the closing force exerted by the leaf in configuration. closed. Indeed, the standard NF EN 12453 provides that the closing force must be set below a maximum value, to limit the risk of jamming or pinching when closing the leaf. To do this, the installers are generally instructed to consider a rope connecting the axis of articulation of the motor arm on the motor and the axis of articulation of the leaf arm on the leaf and to shift, perpendicularly to this rope, the axis of articulation between the motor arm and the leaf arm, for example with an offset of about 15 cm, playing on the point of attachment of the arm on the leaf. The measurement of this lateral offset, compared to the rope which is an imaginary line, is relatively difficult to achieve and some installers are content to estimate with the eye, with a risk of error. This can lead to the application of excessive force at the end of a closing phase of the leaf, or even a risk of jamming of the actuator by knee effect or inverted folding of the arm.

It is known to DE-U-8612331 to immobilize in rotation with respect to each other two arms of an actuator, by engaging a screw in one of the several holes respectively provided at the ends of these arms. The geometry of the structure formed of the arms is then fixed.

It is also known to EP-A-2 360 339 or WO-A-01/42608 to use stops to limit the movements of two articulated arms belonging to an actuator. As long as these stops are not in contact, it is not possible for an installer to identify a relative angular position of the two arms.

It is these drawbacks that the invention intends to remedy more particularly by proposing a new arm actuator that is easier to install, without having to consider an imaginary straight line that is difficult to locate in space.

For this purpose, the invention relates to a leaf arm actuator, said actuator comprising an electric motor, a driven motor arm, on the side of a first end and around a first axis, by the electric motor, and a leaf arm freely articulated, on the side of a first end and around a second axis parallel to the first axis, on a second end of the motor arm, this leaf arm being intended to be articulated, on the side of a second end, on a leaf. According to the invention, the motor arm and the leaf arm carry, respectively at the second end of the motor arm and at the first end of the leaf arm, means defining angular ranges of visual identification of the angular orientation. relative to these arms around the second axis, while the visual identification means comprise at least one mark made on the second end of the motor arm and at least one mark made on the first end of the leaf arm, the rotational position of these marks being dependent on the relative angular orientation of the motor arm and leaf arm, and while the mark of one of the two arms is an angular exclusion zone for the mark of the other arm.

Thanks to the invention, the visual identification means carried directly by the motor arm and the leaf arm, allow to determine, thanks to the angular ranges that they define, their relative angular position in a way that is both intuitive and simple for an installer, which reduces the risk of error.

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of an actuator according to its principle and its mounting method, given only by way of example and with reference to the appended drawings in which:

• the figure 1 is a partial perspective view of an articulated leaf closure system incorporating an actuator according to the invention,

The closure system 2 shown in figures 1 and 3 comprises a fixed post 4 and a leaf 6 articulated on this post around a vertical axis Z8 defined by hinges, only one of which is visible at the figure 3 , with the reference 8.

An actuator 10 is provided to move the leaf 6 relative to the pole 4, in rotation around the axis Z8. This actuator comprises an electric motor 12 mounted on a plate 14 fixed to the pole 4 by means of screws not shown. The actuator 10 also comprises a motor arm 16 and a leaf arm 18 whose longitudinal axes are respectively denoted by X16 and X18. The actuator 10 also comprises a bracket 20 for connecting the leaf arm 18 to the leaf 6.

The motor arm 16 is articulated on the motor 12 about a first vertical axis Z1 parallel to the axis Z8. 162 is the end of the arm 16 by which this arm is articulated on the motor 12.

164 denotes the end of the arm 16 opposite the end 162. This end is articulated on a first end 182 of the leaf arm 18 about a vertical axis Z2 and parallel to the axes Z1 and Z8.

Furthermore, the second end 184 of the leaf arm 18, which is opposite the end 182, is articulated on the bracket 20 about a vertical axis Z3 which is parallel to the axes Z1, Z2 and Z3.

The articulation between the motor 12 the arm 16 is driving in the sense that the end 162 of the arm 16 is rigidly connected to an output shaft of the motor 12, which allows to drive the articulated structure formed of the elements 16, 18 and 20 in rotation around the axis Z1 and, thereby, the leaf 6 in rotation about the axis Z8.

The articulation between the arms 16 and 18 around the axis Z2 is free, in that these arms can freely rotate relative to each other. In the same way, the articulation between the arm 18 and the bracket 20 is free.

Α is the angle, less than 180 °, defined between the axes X16 and X18 around the axis Z2, these axes being oriented away from the axis Z2, each within the arm to which it belongs. As is apparent from the figure 3 this angle has a value between 130 ° and 150 °, in the example of the order of 140 °, when the leaf 6 is in the closed position.

We consider an imaginary line D13 horizontal and intersecting with the axes Z1 and Z3. This straight line constitutes a chord for the articulated structure formed of the arms 16 and 18. Note d2 the distance, measured perpendicular to the line D13 in a horizontal plane, between the line D13 and the axis Z2. This distance defines the offset between the axis Z2 and the rope formed by the straight line D13 in the closed configuration of the leaf.

It is important that this distance d2 is large enough to ensure that the closing force of the leaf 6, when it reaches its closed position, is not too great, at the risk of injuring a user. This stems from the application of the standard NF EN 12453. If the distance d2 is relatively easy to design, it is in practice difficult to measure for a person installing the actuator 10, especially since the line D13 is imaginary.

To allow the installer to identify that the value of the angle α fixed during the installation of the actuator 10 is correct, visual cues are provided on the end 164 and on the end 182.

More specifically, the end 164 is provided with a rib 165 which extends on a rounded portion 166 of the end 164. Furthermore, the end 182 of the arm 18 is provided with a central rib 185 and two ribs 187 and 189 formed on a rounded portion 186 of the end 182.

The ribs 165, 185, 187 and 189 are made by localized extra thicknesses of the outer skins of the arms 16 and 18. As a variant, these ribs could be replaced by recesses formed in recesses in these skins. The fact that the visual cue means consist of reliefs, projecting or recessed, arms 16 and 18 ensures that these reliefs remain visible, even as the actuator 10 is subjected to the weather.

The ribs 165, on the one hand, 185, 187, 189, on the other hand, make it possible to locate, at least approximately, the angular orientation of the axes X16 and X18 around the axis Z2.

We note B1, a defined angular range, on the part 186, between the ribs 185 and 187. We note β1 the angle at the top of the zone B1. In the same way, we note B2 an angular range defined between the ribs 185 and 189 on the rounded portion 186 and β2 the angle at the top of the zone B2.

We denote ℓ185 the width of the rib 185 measured along the portion 186, in a direction from the rib 187 to the rib 189. We note β3 the angle at the apex of an angular sector centered on the axis Z2 and whose rib 185 constitutes the base. The rib 185 thus defines an angular range of apex angle β3 and width ℓ185.

During the installation of the actuator 10, the installer fixes the plate 14 on the pole 4 and then returns the motor 12 to this plate, in a manner known per se. The installer can then mount the articulated structure formed of the arms 16 and 18 and the bracket 20 on the motor 12, by securing the end 162 of the arm 16 to the output shaft of the motor 12. In this configuration, the user folds the end 184 of the arm 18 already equipped with the bracket 20 against the leaf 6.

In order to determine the mounting position of the bracket 20 on the leaf 6, the installer checks the angular orientation of the axes X16 and X18 relative to each other around the axis Z2, by looking at the ribs 165, 185, 187 and 189.

The mounting instruction of the actuator 10 can provide that it is prescribed to the installer to align the rib 165 with one of the ribs 187 and 189, according to the mounting direction of the actuator 10. In this configuration , the manufacturer can guarantee that, insofar as the angle α has a value less than 150 °, the closing force of the leaf 10, in closed configuration, complies with the NF EN 12453 standard, in particular equal to a force nominal closing force whose intensity is fixed by this standard.

The installer can then fix the bracket 20 on the leaf 6 in the position identified by the angular orientation of the arms 16 and 18.

However, it may be that the installer wishes to install the actuator 10 in a configuration where the angle α in the closed position of the leaf 6 is greater than in the case where the ribs 165 and 187 are aligned, as shown in FIGS. Figures 1 to 5 . This can happen when the installer wishes to improve the wind resistance of the installation 2. In this case, the user can choose to slide the bracket 20 along the leaf 6 in the direction of the arrow F1 to the figure 3 , so as to increase the value of the angle α, that is to say to "open" the articulated structure formed of the arms 16 and 18. In doing so, the installer brings the rib 165 next to the zone B1 . This remains acceptable as the rib 165 does not reach opposite the rib 185. The installer can then fix the bracket 20 on the leaf 6 in this position. However, when the installer chooses a closed position of the articulated structure formed of the arms 16 and 18 in which the rib 165 is facing the zone B1, it must proceed to a measurement of the force of impact of the leaf to the closure , to ensure that this force is in accordance with the provisions of the aforementioned standard.

The rib 185 constitutes an exclusion zone of width ℓ185, in the sense that the mounting instructions of the actuator 10 can provide that the rib 165 must not be disposed in an angular zone with a vertex angle β3 opposite the rib 185, otherwise the impact force of the leaf closure could be too large or the articulated structure formed of the arms 16 and 18 might lock by knee effect. Indeed, if the rib 165 is partially or totally opposite the rib 185, then the X16 and X18 axes are generally aligned or, at least, define between them a geometric axis γ, whose sum with the angle α is 180 °, which has a value less than 8 °, preferably 5 °. Given the low value of the angle γ, the effort closing leaf 6 is high and the hinged structure formed of the elements 16, 18 and 20 may lock, by toggle effect.

In other words, the installer uses the angular ranges B1, B2 and 185 to determine the relative angular position of the arms 16 and 18, i.e. the value of the angle α, in the closed configuration. leaf. Indeed, the installer finds, thanks to the angular ranges B1, B2 and 185 the areas in which he can position the rib 165, before setting the bracket 20 on the leaf.

It is noted that the determination of the installation conditions of the actuator 10, in particular of the position of the bracket 20 on the leaf 6, can take place without having to project an imaginary line, such as the line D13, or to measure an offset such as the distance d2 mentioned above.

In the case where the actuator 10 is installed in a configuration opposite to that shown in FIGS. Figures 1 to 5 , the installer proceeds in a manner similar to that mentioned above, except that he aligns the rib 165 with the rib 189, as shown in FIG. figure 6 , or with zone B2, as shown in figure 7 . The position of the figure 7 corresponds to a maximum open position of the articulated structure formed of the arms 14 and 18. Indeed, in this position, even if it is located opposite the B2 zone, the mark 165 is close to the mark 185 which constitutes an exclusion zone, in that the mark 165 must not be aligned with it, as explained above.

Whatever the closure configuration selected by the installer, that is to say that this configuration corresponds to the alignment of the rib 165 with one of the ribs 187 or 189 or with one of the zones B1 or B2, the mounting instructions may provide for the establishment of a stop for the closing movement of leaf 6, when the closing configuration has been determined as explained above. The establishment of this stop can be carried out by inserting a removable stop block under the hood of the motor 12 or by setting up a stopper of the leaf 6 at the end of the closing stroke. . Alternatively, the establishment of the stop must be performed at the elbow connecting the motor arm 16 and the leaf arm 18, as described in EP-A-2 360 339 .

Once this stop in place, the installer can exert on the arms 16 and 18, or even on one of these arms, a thrust force in the direction of closure, that is to say in a direction going beyond beyond the end position. The installer can then verify that the mark 165 remains in a position in relation to marks 185, 187 and 189 which satisfies the rule that the mark 185 must be opposite one of the marks 187 and 189, even facing one of the beaches B1 and B2. In particular, the user can verify that the mark 165 is not opposite the exclusion zone defined by the rib 185.

If this is the case, it means that the articulated structure formed of the arms 16 and 18 may become blocked. In this case, the installer intervenes on the abutment to shift it to bring the mark 165 facing one of the angular ranges B1 or B2 when the thrust force is exerted, which then guarantees a long-term operation of the actuator 10, after checking the impact force of the leaf 6 on closing, as mentioned above.

It is quite appropriate that the angles β1 and β2 have a value of between 30 ° and 45 °, preferably of the order of 38 °. Similarly, the width ℓ185 can be chosen so that the angle β3 has a value between 8 ° and 12 °, preferably of the order of 10 °.

Alternatively, a single mark can be made on the leaf arm 18, while two or three marks are made on the motor arm 16.

The invention has been described above in the case where the predetermined position in which the relative position of the marks 165, on the one hand, 185, 187 and 189, is checked, on the other hand, is the closing position of the leaf 6. Alternatively, this position may be the fully open position of this leaf.

The features of the embodiments and alternatives contemplated above may be combined with one another.
