Definitions

  • the invention relates to an automated door closing device. More particularly, the present invention relates to an automated door closure device, for example of the garage door type intended to switch from a vertical position to a horizontal position or vice versa to obstruct or not a passage and allowing a certified closure and blocked of said door.
  • suction cup type systems Other known devices use suction cup type systems. These devices generally require the presence of a metal part on the door cooperating not with a mobile part of the frame but with an electromagnet applying a holding force on the door with the aid of said metal part of the door.
  • this type of device ensures the closing of the door only when it is close enough to the electromagnet for the latter to produce a suction effect.
  • This device also prevents the sound nuisance of the closure and generates a clacking sound when the metal part of the door contacts the electromagnet.
  • This device also generates a significant energy consumption, requiring the operation of the electromagnet continuously.
  • the security provided by such a device is questionable because any obstacle located between the metal part and the electromagnet prevents the proper operation of the system, and therefore the locking closure, easily providing access to possible thieves.
  • Such door closure locking devices are in particular installed on overhead doors. These doors are for example for garages, private or public, and are usually automated to let the cars without requiring a driver to get off the vehicle to open and close the door. For its opening, the door switches from a vertical position to a horizontal position and generally parallel to a ceiling.
  • the tilting of the door is generally obtained by sliding along lateral guide rails which are mounted on a door jamb. To facilitate the tilting and so that the door remains horizontal despite the weight of the door, it is used in a known manner a traction system connected to the door to counterbalance the weight of the door, for example a counterweight or a system of springs.
  • the motors used are generally asynchronous DC motors or brushless motors (in English, brushless motor). These motors produce a driving force capable of tilting the door in one direction or the other, said force being applied to the lower part of the door.
  • the device according to the invention aims to overcome the drawbacks of the closure systems of the prior art by providing an automated door device ensuring the closing of the door as well as its holding in closed position and its locking without generating nuisance noise or significant over-consumption of energy during its use.
  • the invention aims to overcome this disadvantage in the context of a garage door swinging as described above and known per se. Furthermore, the device according to the invention has the advantage of using the drive force not used by the motor during a driving of the door for its own operation without requiring an increase in the power of said motor.
  • the invention therefore relates to a closure device comprising a closing means of the door, swing, ventail or similar type a drive system being connected to said closing means and causing both closing and opening, a means auxiliary drive unit driving the closure means at the end of the race during its closing, characterized in that the auxiliary drive means is a compression / release operating system, the compression of the auxiliary drive means taking place at the end of the opening stroke of the closing means, the release of said auxiliary drive means causing the driving of said closing means to take place at the end of the closing stroke of said closing means.
  • auxiliary drive means connected to the closing means, typically to the door, ensures the good closing of the door at the end of the race during its closing even in case of difficult weather conditions or malfunction or maladjustment of the door.
  • main drive device the auxiliary drive means replacing or assisting the main drive means.
  • the auxiliary drive means is movable, its displacement being linked to a displacement of the closing means, that is to say that the auxiliary drive means is mounted on a guiding device which may be the same guiding device as that of the door. The movement of the door then causes the displacement of the auxiliary drive means.
  • the device according to the invention comprises a locking system in displacement of the auxiliary drive means.
  • the displacement of the door being linked to the displacement of the means auxiliary drive, blocking it blocks the movement of the door.
  • This locking system thus ensures the maintenance of the closed door because the auxiliary drive means is stopped in a fixed position. This locking of the door is ensured as the locking system of the auxiliary drive means is kept active.
  • the auxiliary drive means is a compression / release operating system.
  • compression / release system means a means that stores energy by compressing itself during a compression phase and releases this energy while developing during a release phase.
  • the compression of the auxiliary drive means according to the invention is performed at the end of the opening stroke of the closure means.
  • the release of the auxiliary drive means takes place at the end of closing stroke of said closing means.
  • a main drive means in the form of a motor that develops the most force at the start of the race when opening the door.
  • This important need at the beginning of the race when opening the door is mainly related to the weight of the door, the weight of the door being in the following movement opening gradually supported by the guide device.
  • the engine At the end of the opening stroke, the engine has an important unused power reserve corresponding to the difference between the initial need in displacement and the current need. This power can be used to compress the auxiliary drive means without the need for a more powerful engine, nor generate significant overconsumption of the engine.
  • the force stored by the auxiliary drive means is advantageously retained until its use at the end of the race in closing the door. This force is released and applied to the door at the end of the race to cause it to close.
  • the auxiliary drive means does not require external power to the device advantageously using the force already available in the system.
  • the auxiliary drive means comprises a compression / release activation system, preferably an automated activation system of said auxiliary drive means.
  • This system cooperates with the auxiliary drive means to ensure that compression and relaxation are performed at the desired times. In activation, this system allows compression or relaxation of the auxiliary drive means. Without activation, the system blocks and does not allow compression or relaxation of the auxiliary drive means.
  • the locking system constitutes a movable stop whose movement is perpendicular to the displacement of the auxiliary drive means. This stop is movable between a locking position limiting the displacement of the auxiliary drive means and a free position not limiting said displacement.
  • the stop When releasing the auxiliary drive means, the stop serves as a fulcrum for said auxiliary drive means by blocking the displacement of its end bearing on said stop.
  • the development of the auxiliary drive means therefore imposes the displacement of its end not bearing against the stop. Said end being connected to the door causes the closing movement of the door.
  • This stop also guarantees the closing lock of the door by preventing its return in opening as the additional drive means abuts against it. A translation of the stop releases the movement of the auxiliary drive means, the latter can then move and no longer blocking the movement of the door opening.
  • the stop of the locking system comprises a beveled non-return ratchet slidably mounted on an activator.
  • the activator controls the movement of the pawl to position it on or off the path of the auxiliary drive means. In a rest position, the activator applies, for example by means of a spring or the like, a force on the pawl keeping it in the path of said auxiliary drive means.
  • the displacement of the auxiliary drive means brings it into contact with the non-return pawl, more particularly the auxiliary drive means comes into contact with the beveled portion of said pawl.
  • the driving means then applies in a direction forming an acute angle with said beveled portion, a force able to move the pawl which, translated perpendicular to the direction of movement of said auxiliary drive means, is moved out of the path of this last releasing his passage.
  • the activator After passing the auxiliary drive means, the activator imposes a return to the rest position at the ratchet, a flat face of said ratchet being then vis-à-vis the auxiliary drive means and blocking its movement in the opposite direction.
  • the abutment of the auxiliary drive means on the flat face of the pawl allows a fulcrum of the auxiliary drive means, this support imposing the development of the drive means by a displacement of its end connected to the door.
  • the blocking of the auxiliary drive means in a direction in the opposite direction prevents the movement of the door opening.
  • Such opening of the door is possible only when the pawl activator slides the latter so as to release the path of the auxiliary drive means, releasing at the same time the door opening.
  • the auxiliary drive means comprises a jack, said jack comprising a push rod and a guide tube, an end of said jack being anchored to the closure means.
  • This type of jack is known in many uses, for example in the field of office chairs, in the trap systems for buses or for some container or furniture.
  • These cylinders comprise a mechanical system of the spring type or gas spring allowing, when activated, to move the push rod located in the tube to compress gas or a spring in one direction or on the contrary to release the compressed gas or this spring in the other direction.
  • Such a cylinder develops over a greater or lesser length.
  • An end of such a jack is according to the invention anchored to the door.
  • the auxiliary drive means is held in abutment by the locking system, the release of the cylinder, corresponding to the output of the push rod of the tube, thus causes the displacement of the end of the cylinder anchored on the door and thus the movement of the door.
  • the device according to the invention comprises an abutment limiting the displacement of the auxiliary drive means at the end of the race in opening of the door, a loading cam cooperating with said auxiliary drive means when the latter is in contact with said stop, said cam activating the auxiliary drive means.
  • the movement of the cylinder is limited by a stop at the end of the race opening the door.
  • This stop serves as a fulcrum to the cylinder.
  • the activation cam activates the jack so that the rod of the latter can be moved in the tube, thus allowing its compression.
  • the contact of the cylinder on the stop corresponds to the contact of the cam on the activator of the jack, that is to say that when the cylinder comes into contact with the stop, the cylinder is activated by the cam.
  • the complete opening of the door causes a withdrawal of the cam releasing the activator by any means known to those skilled in the art, for example by a thrust of a shoulder of the door on the cam causing its withdrawal from the the activator.
  • the cam can also be elastic, the application of a minimum pressure being necessary for the activation of the jack.
  • the drive speed of the opening door can be greater than the maximum speed of movement of the rod in the cylinder tube, and the difference in speed requires a displacement of the cylinder despite the presence of the cam on the activator.
  • the removal of the load cam or the speed difference between the door opening and the maximum speed of movement of the rod in the tube ensures that the cylinder is driven in movement by the door while it is in compression.
  • the device according to the invention comprises a drive cam cooperating with the auxiliary drive means, this cooperation activating the auxiliary drive means at the end of the closing stroke of the closing means.
  • the drive cam allows the release of the auxiliary drive means. This release causes a deployment of the auxiliary drive means driving the door at the end of the closing race.
