Door assembly with automatically moveable wings and method of operating such door assemblies

p0001The invention relates to a door system with automatically movable wings according to the preamble of claim 1 and a method for operating such a door system according to claim 18th

p0002Such door systems are well known. They are executed as straight sliding or telescopic sliding doors or even in a curved shape as a curved sliding doors and revolving doors. The drive of the movable wing is thereby designed electromechanical or electro-hydraulic. In order to enable detection of persons or objects in front of or behind the door, such door systems are equipped with a detection sensor. Once the sensor responds, automatically open the sliding panels.

p0003The object of the invention is to improve the safety of such plants significantly door.

p0004is the problem with the teaching of patent claim 1 and a method for operating such door systems according to claim 1 according to claim 18 Solved.

p0005To increase the safety potential, in addition to the detection sensors sensors as safety sensors are available. These sensors are preferably formed as active infrared sensors. It is understood that any other suitable type can be used by sensors.

p0006The arrangement of the sensors can be done both on the outside and inside of the door leaf. Thus, a passage monitoring by means of sensors is ensured when persons get into the or the detection ranges of the sensor or sensors. Depending on the size of the door, it can of course also to perform only a safety sensor, which covers the entire door width of the movable wing. When a plurality of sensors these are preferably installed side by side with a certain distance in the ceiling area and in the region of the fighter or a headband of a revolving door. The distance is determined by the emission cone and the distance of the sensor to the underlying substrate. The rays of the sensor range while up on the ground, which is self-learning recognized as background information. Once the sensors have learned this background in a learning process, the door leaves can be moved automatically. A change of the background, so the door stops and moves only after a certain programmable time again. After the door is approached again, she has learned this new background.

p0007The sensors are constructed so that they have an elongated radiation area or detection zone. This is to be understood that the length is substantially greater than the width of the detection region. Here already seen a big difference to the known detection sensors, which preferably scan a large area in front of such a door with her leg.

p0008Due to the elongated shape of the detection areas, it is possible, these are arranged at adjacent sensors to realize so that corresponding overlapping portions occur. This ensures that can appear a danger for persons between the coverage areas in any way. The overlapping areas thus offer a very high safety level for people who want such a door system happen.

p0009In order for the sensors to today not interfere with the detection areas themselves, the sensors are preferably connected in groups. This can be for example groups that are formed from the fact that a master sensor interacts with one or more slave sensors. The control of such safety sensors are connected via an electronic circuit that the individual sensors active or not active on the basis of a program, so that at the same time do not overlap detection areas. This switchover is in very short intervals so that the people who pass through such a door system, it is not noticeable.

p0010Thus, simultaneously activates all master sensors and all the slave sensors are disabled or all slave sensors activated and all master sensors are disabled. It is also possible for the master and slave sensors are activated. To this end, located within the master sensor, an electronic circuit that controls by programming the switching between master and slave sensor.

p0011In another particular embodiment, it is possible to connect the sensors, according to the requirements in series. The controller can also here be effected in that both the superordinate electronic control and the controls contained in the master sensors perform a synchronization so that it is ensured that no overlap occurs by the overlap of the detection areas. the operation of such a door can constantly be ensured also by the self-learning of the background information so that no permanent staff needs to put the door back on track, as it is today in the prior art, when a door stops. The door leaves remain so long in the open position, as there is an obstacle within the detection areas. This means with a static obstacle that can not be realized by people who are active, safe operation of the door is always guaranteed. This is because a person can not remain for a longer period in the same position. Because once the person even slightly moved, will take place the detection of the obstacle and thus realized a collision of the door leaf.

p0012The invention is explained below with reference to exemplary embodiments schematically illustrated in the drawings.

p00141 shows a door system 1 is shown, which fits between two adjacent walls 37th This door system 1 can be carried out both as pure straight sliding door or as shown in the following figures as double-sided executed circular sliding doors. The double bow sliding embeds itself between the movable wings 5, 6 on each side of an interior space 29 a. This ensures that in such doorways crossventilation.

p0015Within a headband or fighter 2 are next to a detection sensor 7 with its detection range 14 in the embodiment of security sensors 8, 9 and 10. The arrangement of the safety sensors 8, 9 and 10 is done in such a way that they, at least the entire opening range of the door leaves 5 6 cover. It turns out that the detection areas 11, 12 and 13 of the sensors 8, 9 and 10 are arranged so that there is an overlap region 36 in the central region and the latter to the lateral edges of the wings 5, 6 to the neighboring fixed side walls 3, 4 also be captured even near the ground of the detection areas 11 and 13. FIG. The detection ranges of the sensors 8, 9 and 10 are designed so that their length I is substantially greater than its width b. This results in particular from the figure 6 and the embodiments of Figures 2 to 5. Such a configuration of the detection areas 11, 12 and 13 is a good coverage even with curved vanes 5, 6 possible. This shows in particular to Figure 2, in which the sensors 8, 9 and 10 as well as other sensors 20, 21 and 22 are respectively arranged outside of the door leaves 5, 6 in one embodiment. Their detection ranges 11, 12 and 13 and 17, 18 and 19 cover the entire opening width of each door leaf 5,. 6 Further, by the figure 2 shows that the sensors 8, 9, 10, 20, 21 and 22 are arranged close in front of the door leaves 5, 6, but not so tightly that the detection areas 11, 12, 13, 17, 18 and 19, the sliding door 5, can recognize. 6 Furthermore, it is clear by this illustration that their detection areas 11 and 12 is an overlap region 36, for example, between the sensors. 8 and 9 In Figures 6 and 7 shows how the interconnection of sensors 26, 27 and 28 with their coverage areas 33, 34 and 35 takes place. In the figure 6, only the two outer sensors 26 and 28 are active, whereas the central sensor 27 has been disabled. In a time somewhat later date, which is realized by a non-illustrated electronic control in conjunction with a programmable sequence program, only the sensor 27 is activated, so that no overlap regions 36 of the detection areas 33, 34 and 35 may interfere. Such a circuit way, for example, be achieved by that the sensor 27 are 26 and 28 connected as a master sensor and slave sensors as sensors. Such interconnection can be in groups, as in the still to be described embodiments, a substantial simplification of the electronic circuit to.

p0016In the Figure 3 2 security sensors 23, 24, 25, 26, 27 and 28 respectively in the interior 29 of the door system 1 are respectively arranged close before the doors 5, 6, in contrast to the figure. These sensors 23, 24, 25, 26, 27 and 28 have detection ranges 30, 31, 32, 33, 34 and 35, which are configured similarly to the already described FIG. 2

p0017As the figure 3 can be seen in particular, therefore, the entire security area before the doors 5, 6 is monitored accordingly by sensors.

p0018How is the protection of security restricted areas is executed, decides depending on the application on site. This can happen for a in an embodiment of Figure 2, and in one embodiment of FIG. 3 However, it is also conceivable that, both before and behind the door leaves 5, 6 respectively detecting sensors 8, 9, 10, 20, 21, 22, 23, 24, 25, 26, 27 and 28 are arranged. The number of sensors used is determined by the size of the door leaf 5,. 6 So can be arranged of course contrary to the illustrated here more sensors than three adjacent.

p0019Also in the embodiment of Figure 4 can not simultaneously all sensors 8, 9, 10, 20, 21, 22, 23, 24, 25, 26, 27 and 28 are activated, as otherwise in the overlap regions 36 of the detection areas 11, 12, 13, 17, 18, 19, 30, 31, 32, 33, 34 and 35 the detection of an obstacle would result. For this reason, here, the sensors 8, 9, 10, 20, 21, 22, 23, 24, 25, 26, 27 and 28 are connected together according to the desired design in groups. Further, it is also possible that the master and slave sensors. This may be so, for example, in the interior 15, where a higher security against vandalism is, the master sensors are used and in the outer region 16, the slave sensors.

p0020The execution of a straight sliding door with the door leaves 5, 6 is reproduced in FIG. 5 Here is the one between the side walls 3, 4, the arrangement of the sensors 26, 27 and 28 with their coverage areas 33, 34 and realized 35th This shows that the region between the fixed side panels 3, 4 is so secure that no person may come within the travel area of ​​the door leaves 5,. 6 Analogously to the side between the side members 3, 4 is carried out on the opposite side of the wings 5, 6, the arrangement of the sensors 20, 21 and 22nd Also the detection areas 17, 18 and 19 cover the entire width of the door leaf 5, 6 safely. Also, an interconnection of the sensors 20, 21, 22, 26, 27 and 28 is secured so that a simultaneous activation of two adjacent sensors is omitted in this embodiment.

p0021Before the doors 5, 6 of the detection area 14 of the sensor 7 is shown for detecting sensors respectively in the outer region 16 as well as indoors 15th Also, this arrangement is clear that there is still another higher safety potential is to be found than with conventional doors. In particular, for the lateral region which is not reached by the detection range 14 of the detecting sensor 7 to the door leaves 5, 6, is ensured by the safety sensors used according to the invention.
