Description

  The present invention relates to an operating device for a closed facility or a sunshade facility. The invention also relates to a closed or awning installation comprising such a device.

  Closed equipment means doors, gates, shutters, and equivalent equipment.

  In this type of equipment, a shaft on which a protective plate can be wound more or less according to the rotation of the shaft around the longest axis is provided. The shaft is rotationally driven by a driving member such as an electric motor or a mechanical hoist. However, it is sometimes necessary to disengage the shaft drive system for safety reasons to allow maintenance work on the device or if a current failure occurs in the case of an electric motor. .

  From EP 0 790 385 the use of a screw with a flat part configured to engage or disengage a gear coupled to a pedestal supporting a drive member depending on its angular position It has been known. The interlock release of the drive system is obtained by the rotation control of the screw with a flat part, and such a rotation control is not intuitive for the user, so there is a risk that such an interlock release is incompletely performed. This can cause accidents, especially in emergency or panic situations. Moreover, in such a known device, the interlocking position is the position where the teeth of the screw with the flat part are fully engaged with the teeth of the gear, so this corresponds to the exact angular position of the screw. Such a corner position is difficult to determine for the user. As a result, the linkage may be incomplete or inadequate, in which case the gears and pedestals are not effectively fixed during rotation, so the dynamic chain driving the shaft wears out prematurely and malfunctions. Increased risk.

European Patent No. 0790385 U.S. Pat. No. 4,446,910 German utility model registration No. 8519421 British Patent No. 205564, Swiss Patent No. 386876

  The present invention is a device that can be operated with complete intuition so that the interlocking position, that is, the position where the fixing point of the driving member of the winding shutter is effectively formed can be easily found without searching for the difficult angular position to estimate. In particular, it is aimed to eliminate the above-mentioned disadvantages.

  For this reason, the present invention relates to an operating device for a closed facility or a sunshade facility provided with a shaft that is rotationally driven by a member that is supported by a pedestal that is non-rotatably coupled to a gear. The operating device includes a lock bolt. The lock bolt has a first position where the lock bolt prevents rotation of the gear by the action of a traction force and an elastic return force exerted by a user, and the lock bolt includes the lock bolt. It is controlled by a member that translates between a second position that does not interact with the gear.

  According to the present invention, the user can intuitively know how to use the translation member, and can easily obtain translational movement by pulling the operation rod or the operation belt including an emergency situation or a panic situation.

  According to features of the invention that are advantageous, but not essential, the device includes one or more of the following features.

  Means are provided for resiliently biasing the translation member to the first position. The means may include a compression coil spring that exerts a return force directed to the gear on the translation member, or a member that is dynamically coupled to the gear during rotation. Therefore, when the drive member does not act positively on the device to release the interlock, the elastic means reliably fixes the gear with a predetermined value, that is, the drive member is interlocked.

  According to some embodiments of the present invention, a pinion that engages the gear teeth is disposed in front of the lock bolt, and the pinion rotates when the translation member is in the first position. Be blocked. Since the pinion can include a rotation shaft that is displaced in the axial direction with respect to the rotation shaft of the gear, the pinion can be positioned so as to make the lock bolt and the translation member facing each other approach very easily.

  The lock bolt is engageable between two adjacent teeth of the pinion when the translation member is in the first position. The pinion can be effectively fixed by the one or more protrusions, so that the gear is effectively fixed.

  According to another advantageous embodiment of the invention, the locking bolt is engageable between two adjacent teeth of the gear when the translation member is in the first position.

  The gear or pinion is non-rotatably connectable to a ring with at least one notch that selectively receives a lock bolt. This feature of the invention allows the shape of one or more notches provided in the ring to be adapted to the locking function. In particular, the side surface of such one or more notches can be configured to be substantially perpendicular to the stress exerted on the lock bolt by the gear under the load provided by the installation. Advantageously, there are a plurality of notches distributed approximately regularly around the periphery of the ring. Further, the ring may be integrated with the pinion.

  In either embodiment, the locking bolt can be a blocking pin that is slidable along a direction substantially perpendicular to the translational direction of the translational member.

  The present invention also relates to a closed facility or an awning facility including the operating device as described above. Such an installation is economical, and it is possible to implement the interlocking or disengagement of the portion that forms the fixed point of the mechanical or electrical operation member with high reliability.

  BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood and other advantages will become apparent when reading the following description of three embodiments of an operating device adapted to its principles, given by way of example only, with reference to the accompanying drawings Will.

  1 to 3 includes a winding shaft 2 controlled by a protective plate 18. The cylindrical motor accommodated in the shaft 2 is constituted by a so-called fixed casing 3 including an electric motor 4, a speed reducer 5, and a stroke end device 6. The pedestal 7 that supports the casing 3 is attached to the fixed control table 8 via a shaft 7 a that enters a housing 9 that is fixed to the control table 8.

  The ring 10 coupled to the shaft 2 includes an internal tooth row that cooperates with a pinion (not shown), and transmits the movement of the shaft 2 to the stroke end device 6. The output shaft of the speed reducer 5 supports a disk 11 that engages with the shaft 2, and can transmit the rotational motion of the electric motor 4 to this shaft.

  On the other hand, a compression coil spring 12 is accommodated near the other end inside the shaft 2. One end of the spring 12 is attached to a disk 13 fixed inside the shaft 2, and the other end is connected to a second disk 14 that is coupled to the shaft 2 so as not to rotate relative to the shaft 2. The shaft 15 supports the disk 13 and is fixed to the control table 17 by a U-shaped metal fitting 16.

  The protection plate 18 of the winding shutter can be moved along the winding direction of the shaft 2 by the rail 19 as indicated by a double arrow T. Due to the rotational movement of the shaft 2 corresponding to the closing of the opening with the winding shutter, the spring 12 is gradually tensioned so that the spring accumulates energy.

  The gear 21 is coupled and attached to the shaft 7a so as not to be relatively rotatable. The base 7 must constitute a fixed part so that the electric assembly 3-6 can function properly. In other words, the gear 21 must be held at a predetermined angular position about the geometric axis X-X 'of the shaft 2, 7a.

  For this reason, and as can be seen in particular from FIGS. 2 and 3, the tooth row 21a of the gear 21 is centered on a geometric axis AA ′ substantially parallel to the axis XX ′. Engage with. The pinion 22 is installed in the groove 9 a on the side surface of the housing 9 so as to face the piston 25. The piston includes a lock pin 25a dimensioned to be engageable between two adjacent teeth 22b of the tooth row 22a. The piston 25 is disposed in the second groove 9b of the housing 9 so as to be translationally guided along a direction Y-Y 'perpendicular to the axis X-X' and the axis A-A '. The direction Y-Y ′ is a radial direction with respect to the lock bolt 22 and the axis A-A ′.

  Actually, the piston 25 has a cross-sectional shape that is close to the internal cross-section of the groove 9b, and is engaged with a surface perpendicular to the direction Y-Y '. In this way, the piston 25 is translated and guided in the groove 9b along the direction Y-Y '.

  Thus, the piston 25 is between a first position where the pin engages the tooth row 22a of the pinion 22 and prevents its rotation, and a second position where the pin 25a does not interact with this tooth row. The movement of the lock bolt formed by the pin 25a can be controlled.

The piston 25 is coupled to a rod 25 b extending substantially along the direction YY ′, and passes through an opening 9 c provided in a lower portion of the housing 9. The rod 25 b is coupled to a cord 26 that can exert a traction force F ₁ on the piston 25 that allows the pin or lock bolt 25 a to be released from the teeth 22 b of the tooth row 22.

Furthermore, compression spring 27 is disposed around the rod 26 within the groove 9b, exerts a stress F ₂ of the pinion 22 always piston 25.

The operation is as follows. The stress F ₂ specified value which spring 27 exerts, pin or lock bolt 25a is this fixed 25 by inserting the pinion 22 between the two teeth 22b. Since the pinion 22 is prevented from rotating about the axis AA ′, the pinion itself fixes the gear 21 and constitutes a fixing portion of the electric assembly 3-6 together with the shaft 7a and the base 7.

  In particular, if the motorized assembly must be disengaged in order to directly operate the protection plate 18, it is only necessary to apply the stress F1 to the cord 26. Due to this stress, the spring 27 is compressed and the pinion 22 is released, so that the pinion and the gear 21 with which the pinion engages are centered on their respective axes AA ′ and XX ′. Can rotate.

  When the interlocking of the electric assembly 3-6 is released, the compression coil spring 12 continues to exert the winding stress of the shaft 2, so that the protection plate 18 does not fall.

When the electric assembly is to be interlocked again, the traction stress F ₁ may be released. As a result, the spring 27 presses the pin or the lock bolt 25a against the tooth row 22a again, so that the pinion 22 and the gear 21 are immediately fixed around the individual axes. The user does not need to search for an optimal angular position as in the known prior art described in European Patent No. 0790385, and the base 7 is effective around the axis XX ′ as long as the traction force F ₁ is released. It turns out that rotation is prevented.

As can be seen in particular in FIG. 3, the lock pin 25a can have a width l _25a approximately equal to the width l _{22b of the} tooth 22b.

  In the second embodiment of the present invention shown in FIGS. 4 and 5, the same reference numerals are added to the same members as those in the first embodiment. In this embodiment, the pinion 122 is engaged with the tooth row 121a of the gear 121 by the tooth row 122a, and this gear is coupled to a pedestal constituting a fixing portion of the electric motor (not shown).

  The rotation axes of the gear 121 and the pinion 122 are denoted by X-X ′ and A-A ′, respectively.

Similarly, the pinion 122 is accommodated in the groove 109 a of the housing 109 including the gear 121. The piston 125 is slidable along the direction YY ′ perpendicular to the axes XX ′ and AA ′ within the groove 109b. The piston 125 supports a rod 125 b that extends along the YY ′ direction to the outside of the housing 109. This rod is coupled to the traction cord or pull cable 126, this code or cable, the elastic stress F ₂ of the spring 127 exerts the compression action is disposed around the rod 125b in the groove 109b opposite stress F ₁ can be the cause.

  The difference between the second embodiment and the first embodiment is that the piston 125 includes a protruding lock portion 125c aligned with a ring 122c integrally formed with the pinion 122. The ring includes four notches 122d distributed about 90 ° about the axis A-A ', each notch capable of selectively accommodating a protruding lock portion 125c.

  Thus, the protruding lock portion 125c forms the lock bolt of the ring 122.

  Since the ring 122c is coupled to the pinion 122 so as not to rotate relative to the pinion 122, the ring 122c does not interfere with the tooth 122b of the tooth row 122a, that is, without damaging the surface cooperating with the tooth of the tooth row 121a. By introducing the lock portion or the lock bolt 125c into one, the rotation of the pinion can be prevented.

Further, the side surfaces 122 _d1 and 122 _d2 of the notch 122d are substantially parallel to the YY ′ direction when the corresponding notch 122d covers the lock portion 125c. Thus, these surfaces are substantially perpendicular to the stresses F ₃ and F ′ ₃ caused by the torque C received by the gear 121. This torque tends to cause the gear to rotate about axis XX ′ by actuation of the electric assembly. In fact, the torque C has a tendency to rotate the pinion 122 about the axis AA ′, ie move the side surfaces 122 _d1 and 122 _d2 perpendicular to the YY ′ direction.

  As described above, it can be understood that all components in the radial direction of the stress transmitted from the side surface to the lock portion or the lock bolt 125c can be eliminated, and the shape of the notch 122d can be easily adjusted to the lock function. In this way, the torque generated when the lock portion 125c is removed from one of the notches 122d is prevented from being too strong.

  This is an advantage over the embodiment of FIGS. 1 to 3 where the shape of the teeth 22b is not modified to obtain such stress distribution.

  In the third embodiment shown in FIG. 6, members similar to those in the first embodiment are given the same reference numerals with 200 added thereto. The housing 209 of this embodiment includes a gear 221 having a tooth row 221a, which is centered on its rotational axis X-X '. The piston 225 slides in the groove 209b of the housing 209 along the Y-Y 'direction substantially perpendicular to the axis X-X'. A direction perpendicular to the directions of the axes X-X ′ and Y-Y ′ is denoted as Z-Z ′.

The spring 227 exerts an elastic stress F ₂ on the piston 225 toward the bottom of the groove 209 b, that is, upward in FIG. 6.

The piston 225 is likewise includes a rod 225b, the code 226 can be coupled to the rod, it is possible to exert a stress F ₁ opposite to the elastic stress F _2, also in the lower part of FIG 6 with the groove 209b The piston 225 can be slid.

  The piston 225 also includes a head 225e that is coupled to a similar head 225f via a slope 225g with respect to the Y-Y 'direction. An inclination angle of the gradient portion 225g with respect to the Y-Y 'direction is α. This angle is from 10 degrees to 35 degrees, preferably about 25 degrees. The gradient portion 225g passes through a window 225h formed in the lock pin 225c. The lock pin is guided by the opening 209c and the groove 209d of the housing 209, and is slidable along an axis Z-Z 'that intersects the X-X' axis and is perpendicular to the Y-Y 'direction. Accordingly, the movement of the lock pin or the lock bolt 225c is performed substantially along the radial direction with respect to the gear 221.

  The front end 225i of the lock pin 225c, that is, the end facing the tooth row 221a is shaped so as to be able to enter between two teeth adjacent to this tooth row. The rear end 225j of the lock pin 225c has a cross section that matches the cross section of the groove 209d so as to translate the lock pin 225c along the Z-Z 'axis.

  Thus, depending on the position of the piston 225 along the Y-Y 'direction, the lock pin or the lock bolt 225c is translationally controlled along the Z-Z' direction.

By exerting a tractive force F ₁ to the code 226, it is also possible to retract the lock pin 225c toward the bottom of the groove 209d, whereby the gear 221 is rotated around the X-X 'axis is released.

On the other hand, when the stress F ₁ is released, the spring 227 pushes the piston 225 by the stress F ₂ , and when the gradient portion 225g reaches a position where the front end 225i of the lock pin or the lock bolt 225c is pushed toward the tooth row 221a. The rotation of 221 is prevented.

  According to a variant embodiment not shown of the present invention, the same type of blocking piston as in the first and second embodiments is selected selectively from the gear teeth by means of the pin 25a type locking bolt of the first embodiment. Can be slid in the radial direction with respect to the gear.

  According to a variant embodiment (not shown) of the invention, the lock bolt is rotatable and can follow the action of the translation piston. This piston pushes the lock bolt towards the pinion or gear teeth as in the illustrated embodiment.

  The present invention has been described above with respect to a winding shutter driven by an electric motor. However, the present invention can be applied to any type of drive device, particularly when a mechanical winder is used.

  The invention is not limited to the described embodiments, but its technical features can be combined with one another. In particular, a ring with a notch may be attached to the gear of the third embodiment so as to cooperate with the corresponding locking bolt.

  The present invention has been shown for the shaft 2 which serves to wind up the protective plate 18 more or less. However, the present invention is applicable to any type of closure or sunshade installation, particularly when the shaft controls a swing door, slide door, or revolving door.

It is a partial notch front view of the winding shutter containing 1st embodiment of this invention. It is sectional drawing by the II-II line of FIG. It is sectional drawing by the III-III line of FIG. FIG. 3 is a view similar to FIG. 2 of an apparatus according to a second embodiment of the present invention.
