Description

The invention relates to a door device with at least one door to Opening and closing a passage, in particular a passage in the shops comprising at least one door on a Door bracket is movably mounted and comprising an air curtain generating blower before the passage. Such door devices (e.g., U.S.-A-3,350,994) are used to protect the salesrooms against the ingress of cold Air to protect the climate within the sales area optimally to design, this should be prevented at the same time, that from the outside incoming air currents suddenly penetrate into the interior. At a first Arrangement that provides a double-wing door are door brackets intended. In front of the door brackets on the outside is one each Pillar provided for the air outlet of the blower, this case, the column on the passage side facing both an air inlet and also an air outlet side. It has been shown that such Shields do not work properly because of the arrangement of Inlet and outlet openings side by side no real air curtain before the passage is achieved. The effect of this arrangement raises itself on.

It has also been proposed, from below before the passage one Blow air curtain up. However, this is considered by the user uncomfortable, especially when the customers by the Passing through, there is a risk that their clothes or skirts after to be blown up.

Overall, in this known embodiments of disadvantage that the Fresh air intake takes place outside, leaving cold air for the air curtain is used. Although it has been proposed to provide heaters, to warm the air curtain. However, this is very energy reasons costly and not necessary.

The object of the invention is therefore to provide a door device of the above mentioned type to be designed so that a secure shield of the Passage is granted that to produce the air curtain only one low energy consumption is required. Next is for the user the Do not go through such a shielded doorway uncomfortable. Finally, the door device itself be easy and inexpensive to assemble and manufacture. This task is inventively achieved in that the door holder in the interior a picture with one on the side of the door Air outlet has that intake and the elongated Outlet opening substantially over the entire height of the door extends and that the air inlet opening remote from the outlet opening lies, this shields emerging from the outlet opening Air curtain from the passage. By using a door bracket with a recording to create an air curtain results in a easy installation. It does not take more expensive installations to be hit. It just gets the door with its brackets manufactured and installed. After connection to the power supply is an air curtain generated, wherein within the doorway a Shielding occurs. The supporting parts of the door device are, by the shield generating blower and the storage of the door in the Door bracket, integrated. The installation requires only the installation of the Post-like door holder.

The fact that the outlet opening extends beyond the door height results the advantage that overall a large shield is present, the shields the entire passage. The main advantage is that the recording on the side facing away from the door an air inlet opening This ensures that exit and entry into the Recording on different sides of the door is done. To generate the Shielding air curtain therefore does not need expensive heating to heat the Be created. It is also advantageous if the door bracket Post-like construction, so as to perform a simple installation can, since only one post must be installed in the passage. It is particularly favorable if the recording of the door holder a the Air curtain generating fan, especially tangential fan receives, this is immediately before the outlet of the Air curtain generated while on the other side of the post the Intake occurs. Of particular advantage here is that the Door jambs and the doors themselves are easy to install, in particular do not need subsequent changes in the wall opening be carried out in order to carry out the installation. Of the Door jamb with blower can be delivered with the doors at the same time to create the simplest possible installation. The post takes on one Side the door and the outlet on and on the other side of the Entry.

In the particular embodiment of the invention, the rotor of the Tangential fan in the receptacle a diameter <= 90mm, especially 45mm. Such an arrangement allows a narrow Training the door jamb, so that such tangential fans or Blowers with the posts are easy to install. It is recommended that that the inclusion of the door bracket with inlet and outlet opening a Has a size about twice the diameter of the rotor of the Tangential blower corresponds. With such a training arises the advantage that, despite the small diameter of the and outlet openings can be installed in the post. Of the Advantage of the tangential fans with such rotors, the so in the Diameter are small, ensuring that no large Mass movements occur when the rotor is running. In addition, are such rotors quietly in operation. The further advantage of such rotors is that with a door height of 2m and more the Tangential fan has only a single rotor in the receptacle. This in turn results in a cost-effective production and a easy assembly.

It has been shown that the angle of attack of the air flow with respect to the formed by the closed door line is 7 °. Here, the Airflow away from the door, so by pointing this way when the door open, safe protection against the ingress of air, in particular contains cold air. Such a flow of air that blows away from the door, moreover, it ensures that a secure seal is guaranteed.

In a particular embodiment of the invention, the off the outlet opening passing air flow at a speed of at least 2m per second. At such a speed is one secure sealing with the door open. In addition, will Ensure that no foreign air in the door closed Space can enter.

It is recommended here that the outlet opening lies on the outside the passage, while the inlet opening, in particular at the Inside the passage lies. This allows air from the interior be sucked out, which is already heated and used to generate the Air curtain serves and thus creates a safe comfortable shielding. In addition, to some extent, air renewal in Inside done without the fresh air is blown.

In a particular embodiment, the door device comprises two Doors, each door holder having a receptacle with outlet having. In this way can easily a double door created, which is important in large stores.

In a further embodiment of the door device contributes to the the passage side facing the door mount a sensor for Monitoring. With the help of this sensor, it is possible, on the one hand, any to detect disturbing objects in the path of movement of the door and thus to slow down a door movement, on the other hand - which is even more essential - is the possibility of creating an anti-theft device via the sensor, i. e. if goods are removed from the store that are not yet from one Theft protection are exempt, these can be directly at the door be established, without it being customary, special racks or To set up limitation parts. The scope of the Door device according to the invention is thus increased.

It is also important in a first opening area of the door To drive fans under partial load, so as to save energy costs. It has namely shown that the fan, operated under part load, perfect sufficient to make a shield at a lower door opening.

It is also essential if the first opening area by a Sensor is scanned so as to be able to set the exact part safely.

Further it is recommended, if with switched on Door opening automatic but door closed the fan under part load moves, so as to prevent the door opening, the start of the Blower draws too much power from the grid. When operating the fan and Switching the power does not need a large amount of power suddenly from the Electricity network to be withdrawn. This is especially true when starting from one certain opening range, the fan is switched to full load, to safely take over the full screen of the passage.

In order to be able to adjust the airflow at the outlet opening, It is recommended that a Verstelldüse in the slot-like outlet opening be provided so that, depending on the circumstances, in particular structural Construction the optimal shielding is achieved. This adjustment can also be remotely controlled.

In a further embodiment of the invention, the detection takes place the pivoting movement of a door designed as a door by a Sensor on both sides of the swinging motion of the door leaf. To this This ensures that in both movement sections a Security against objects in the trajectory or one Anti-theft device is given.

According to the invention is when using a double door during movement only a hinged door the generated opening of the passage through the Air curtain of the blower of a door shielded. The other fan the closed door either does not run at all or under part load to save energy this way. To simplify door installation For hinged doors, it is recommended that the axis of rotation of the hinged door within the Post-like door holder to lay so proper Door opening and door lock to receive and at the same time to ensure that the door is as close as possible to the door jamb.

In a further particular embodiment, the inlet opening the blower upstream of an air duct, the limitation of a double-walled disc is attached to the door bracket side facing away from the door has an air inlet, this forms the Interior of the double disc the air duct. This disc-like Air duct allows the air supply optimally to the inlet opening of the To perform blower of the recording, at the same time is the suction of the Air the boundary plate of the air duct on its inside so far struck that constant moisture can be abducted. On the other hand Ensures that these discs through the introduced airflow be cooled or heated, causing a heating of the cooling of the Temperature of the air curtain is possible.

In a particular embodiment, this is in a receptacle arranged blower designed as a tangential fan, in this case, the Motor on both sides of the axis of rotation in each case a rotor section. This measure allows a high stability of the tangential fan, so that with a greater power and thus more effective and is more effective.

The door device 10 shown in Fig. 1 has two post-like Door brackets 11, on each of which a hinged door 12 is attached. The Swing door is pivotable by means of door hinges 22 about a rotation axis 24 at the post-like door bracket 11 stored.

Inside the door holder 11, a receptacle 13 is provided. These Recording 13 carries a blower, such as tangential fan or, like it too is called, cross-flow fan. The picture is with a Outlet opening 15 provided for the blower and with a Inlet opening 16.

The door device 10 closes a passage 19. The door holder 11 is in part with its one side on the wall 18 of the Continuity attached. As can be seen in particular from FIGS. 2 and 3, is the inlet opening, so the suction port of the blower 14 on the Inside 25 of the passage 19 provided while the outlet opening 15 outside the passage 19 is located sideways next to the gullwing door, so that in front of the hinged door on the outside of an air curtain 20 may arise.

It should be noted here that the axis of rotation 24 of the double door 12th is provided within the receptacle 13 of the door bracket 11.

At the lower end of the post-like door holder 11 is a sensor in each case 17 provided. This sensor monitors a defined angular range with respect to the axis of rotation of the hinged door. Within this sensor area the blower operates only under partial load. In this case, the sensor extends from a middle position from on both sides of the pivoting, as shown in FIG. 2 and 3 show.

It should be noted here that about this sensor or others Sensors also monitoring the door passage occurs, namely in such a way that any object lying in the path of movement of the door determined and lead to a shutdown of the door movement and that this Sensor serve as theft protection, for example, if customers through go outside the passage. Because, if these customers have goods with them that are not yet free from theft, automatically displayed by an alarm.

It should be noted here that the outlet opening 15 with a nozzle 21st may be formed and that to the air curtain beam 20 easily in to change his direction. According to the embodiment Fig. 5, the door device 10 consists of a double sliding door. The two Sliding doors 23 are doing on the inside 25 of the passage 19th guided, wherein the movement range at the door opening by a along the trajectory provided sensor could be set. Another sensor is again directed to the passage.

In the embodiment of FIG. 6, the door means with a Hinged door, on the side of the door bracket 11 facing away from the hinged door 12 a double disc 26, which in its interior an air duct 27th carries, in this case, the double disc 26 extends to the wall 18 of the Passage 19. The air duct is on the one hand at the Entrittsöffnung 16 of the recording provided. On his other side it opens into an opening 28 through which air is blown when the blower is actuated via the air duct 27 in the door holder for receiving 13 and the blower can be sucked or pressed (see Figs. 5 and 6).

To operate the door device, it should be noted that at switched door device 10, the fan 14 moves in partial load. These Partial load is used to switch to full load when the door is open is possible without suddenly too much power from the mains can. The air duct 27 has still the task of the passage of the Shielding door device next to the two door brackets 11 and that such, if it is supplied with an air curtain. By the double-walled glass panes can be located over the intervening entire disc engaging guide channel 27 a cooling or Heating can be controlled optionally, depending on the Outside temperature. Since the intake air is from the inside, there is a Cooling of the double disc in the summer, if this disc due to Solar radiation is strongly heated. In winter it gets easily through the Room internal temperature heats up.

It should also be noted that still sensors in the field of Passage 19 of the door are provided, which determine whether persons are themselves approach the passage or not.

It should also be noted that via an automatic control the Door opening can be regulated so that optionally only one door is movable so as not to unnecessarily waste energy in winter operation, be it to move the door, be it to shield the passage.

The inlet opening for the fan is located on the inside 25 of the Passage 19, while the outlet opening is located on the outside to so to be able to create an air curtain in front of the door, here is the Air jet slightly directed away from the door, so from the outside to be able to better intercept incoming cold air. By the Inlet opening in the interior is also ensured that the Air curtain on the outside only with heated air from the interior is moved.

It should be mentioned here that the air curtain jet from the door bracket 11 only half of the passage, so the width of the hinged door or the width of the passage sweeps. In the middle, the two meet Rays in a double door and form an outward facing Flow.

As already mentioned, the illustrated embodiments are only For example, realizations of the invention. This is not on it limited. Rather, many modifications are possible. For example, at different locations of the door brackets different acting sensors be present, could also be the divide slit-like outlet into individual opening sections. The adjustment nozzle could possibly be adjusted automatically and indeed in Dependency, such as the outside temperature. Next is said in that the tangential fan comprises a rotor having a length which the door height corresponds. The diameter of the rotor is 90 mm or less, so that the inclusion of the door bracket is designed relatively narrow. The discharge angle of the air flow is 7 ° from the closed door the door away. The air flow of the rotor has a Exit speed of at least 2m per second. It is still here submitted that the air outlet opening and the air inlet opening of the Recording are separated from each other, the air inlet opening on the the door is facing away from the door.

This is to be understood that the air inlet opening to the side of the door and / or rotated by more than 90 ° to the outlet opening.
