Description

The invention relates to a revolving door for a building installation, having opposing drum walls and a ceiling body with an end edge, a turnstile having a plurality of wing elements being rotatably arranged between the drum walls, and wherein the drum walls and the end edge, together with a door bottom that is accessible to a user, have edge areas Form an entry opening for the user to enter the revolving door. The invention also relates to a method for operating such a revolving door.

STATE OF THE ART

Illuminated revolving doors with a signal display for malfunctions or for a special operation, such as a fire, are generally known from the prior art.

the EP 2 754 821 A2 discloses, for example, a revolving door with a light ring which is arranged around the ceiling-side motor. A similar lighting device is disclosed in US Pat EP 3 034 759 A1 . The lighting devices of the revolving doors have in common that they only fulfill a simple function for illuminating the accessible area of the revolving door without providing a further signal function.

However, it is desirable to provide a walker with additional information when entering the walk-through area, which the walker can grasp and understand intuitively without paying heed attention. Particularly in the event of a fire, when smoke impedes or even prevents the view, it is desirable to make the area of a revolving door detectable as quickly as possible for a person who is actually passable, in particular without the turning movement of the turnstile slowing down or stopping.

Another important aspect for improving a revolving door is to be seen in the fact that the flow of people can be improved by positively influencing the access behavior, so that more people can effectively get into or out of a building through the revolving door without interference. In addition, a more even running behavior of the revolving door without frequent slowing down and acceleration and without emergency stops protects the drive and bearing components and ensures a longer service life.

Last but not least, there is a risk of collision with and / or the risk of being trapped between elements of the revolving door for people who may be restricted in their orientation and mobility because of the smoke gases, which must be avoided. In this respect, the convenience of the revolving door is to be improved as well as the security in dangerous situations.

DISCLOSURE OF THE INVENTION

It is therefore the object of the present invention to counter the aforementioned disadvantages and to create a revolving door which offers greater ease of use and which also improves safety in dangerous situations.

This object is achieved on the basis of a revolving door according to the preamble of the independent claims in conjunction with the respective characterizing features. Advantageous further developments of the invention are given in the dependent claims.

The invention includes the technical teaching that a revolving door for building installation has two opposing drum walls, between which a turnstile having a plurality of wing elements is rotatably arranged as part of the revolving door. To this extent, the revolving door comprises the turnstile and possibly also a door base. The revolving door can consequently have a door base that can be walked on by a user, depending on the design. Alternatively, the revolving door, having the drum walls, the turnstile and the ceiling body, is built on such an accessible door base which is already present on site and which the wing elements slide over when the turnstile rotates. The door base can thus be an optional component of the revolving door, but it can also form an on-site base on which the revolving door and its components are placed. Drum walls, the front edge and the ceiling body thus form edge areas of an entry opening for the user to enter the revolving door, the door base being part of the entry opening, but not necessarily being part of the revolving door. In other words, the drum walls and the front edge together with the door base that a user can walk on form, at least in the installed position, edge regions of an entry opening for the user to enter the revolving door.

According to the invention, the revolving door has at least one lighting means which is arranged on at least one edge region of the entry opening and / or on a main closing edge of at least one of the wing elements to form a light signal function. In the context of the invention, the lighting means is formed by means of one or more lighting elements such as LEDs, OLEDs, light strips or light tubes, which are arranged in a certain way, optical elements can also be provided which change the light emission of the light emitting element or elements, e.g. B. diffuser films, light guides, optical deflection elements such as prisms or mirrors and the like.

In particular in the case of smoke, this makes it possible, for example, to make people recognizable where the passage through the revolving door is to be found. A walking direction can also be signaled, for example in the form of a running light or an alarm. And since the passage is always optically detected by the people entering the revolving door, it can be assumed that these people also register the light signal function with a very high degree of probability, even if their perception is restricted.

The at least one lighting means preferably has an elongate extension and forms a light band when in operation. Such a light band has the advantage of being able to make an area such as the passage area to the turnstile clear via luminous line emitters in the form of a light frame.

For the optical clarification of the passage area between the drum walls, but in front of and or behind a moving wing element, the lighting means is designed to emit at least two different light colors, in particular red and green colors. This enables people, for example, to show the extent to which the passage area is still large enough to step through with a moving wing element (green color) or is already too small due to the pivoting movement of the wing element (red color).

In this context it must be mentioned that only one color can be sufficient, e.g. if a red signal is only displayed when the passage is not supposed to take place. Alternatively, an exclusively green light signal would also be conceivable, which indicates that the access opening is still large enough, for example.

At least one lighting means is also arranged on the drum walls, in particular on a rear edge and / or on a counter-closing edge, which form lateral edge regions of the inlet opening. These thus fixed lighting means can, for example, optically limit the delimitation of the respective passage area, which benefits the perceptibility for the pedestrian.

Again, additionally or alternatively, the lighting means can be designed at least in sections over its elongated extent to emit light of different colors. This makes it possible, as an example, to let the light source shine red in the area of the left half of the passage area between the drum walls and to let the right half shine green. This shows the people which area is currently intended or suitable for passing the revolving door. If the pedestrian enters the area that is at least partially limited by green light, the turnstile can continue to turn unhindered. The red area indicates the area in which the turnstile slows down the turning movement when intentionally walking through it, stops it or there is even a collision with the sash or, for example, with the main closing edge.

In this case, a color boundary between the sections of the light with different colors can be generated over the longitudinal extent of the illuminant, which border is variable in position over a longitudinal extent of the illuminant. With regard to the aforementioned example, this enables a person to be able to map the respective area of the passage area, depending on its passage width, either in front of or behind the wing element while the wing element is moving further. The edge or frame of the area that is no longer accessible can then change, for example, from green to red.

In all of the aforementioned revolving doors, at least one sensor can be set up to monitor the closing edge. The at least one lighting means is designed to be operable as a function of a sensor signal from the sensor for monitoring the closing edge. As long as there is no threat, this lamp shines green or not at all. If someone gets into the danger area, this light source can be activated, shining red as an example or even flashing, even before the turnstile slows down or stops rotating.

Alternatively or additionally, at least one sensor can be set up for person recognition. In this case, the at least one lighting means is designed to be operable as a function of a sensor signal from the sensor for person recognition. Person recognition can include the identification with regard to the authorization to be allowed to pass through the revolving door and / or the recognition when a person approaches the revolving door. In the first-mentioned case, the at least one lamp can shine green if the recognized person is allowed to pass the revolving door. In the second-mentioned case, the at least one lamp can shine green when the recognized person can safely enter the revolving door, and otherwise be dark, for example.

Again, as an alternative or in addition, the at least one lighting means can be dependent be designed to be operable from the position of a turnstile wing element located in the passage area between the drum walls (= inlet opening) in the inlet opening. If this wing approaches a drum wall, for example, this lamp can be activated flashing red to indicate that the area between this wing and the closest drum wall may no longer be entered.

The invention also includes a method for operating one of the aforementioned revolving doors. A control is provided by means of which the at least one illuminant is operated in such a way that when the turnstile is rotating, the illuminant optically displays a walkable area within the entrance opening to the user of the revolving door when he enters the entrance opening. This enables the person to avoid getting too close to the dangerous areas of the revolving door and thus unintentionally braking the revolving door or even bringing it to a standstill. This serves the continuous operation of the revolving door and thus the operational safety.

The area that can be walked on is preferably displayed by means of various switch-on and switch-off modes and / or by means of the at least one lighting means, in particular with a red and a green light color. Green can be used to signal that the accessible area can be entered safely, whereby safe means that there is no danger and / or that no safety circuit triggers a safety function such as braking the turnstile.

Alternatively or additionally, when the turnstile rotates, the inlet opening is divided into a continuously decreasing front wing area and a continuously increasing rear wing area of the wing element located in the respective inlet opening. By means of the controller, the at least one lighting means is controlled in a temporally and / or color-changeable manner as a function of the size of the front wing area and / or the rear wing area, in order to display a suitable entry area to a user. This can be used to signal whether the area on the left or right side of this wing element should currently be better entered as a suitable entrance area.

The illuminant (s) that indicate the suitable entry area can be operated with green light, and the illuminant (s) that indicate an unsuitable entry area can be operated with red light. This is a particularly easy-to-understand signaling with regard to the two entry sub-areas to the right and left of the wing element in question.

In each of the aforementioned methods, in order to display a suitable or unsuitable entry sub-area, a lighting means formed with an elongated extension can have a first light color, in particular red or green, over a first length and a second light color, in particular again red or green, over a second length. operate. The position of the transition between the first light color and the second light color is variable. This makes it possible to visually map the enlargement or reduction in size of the respective entry sub-area, for example the position of the transition of the light color can move along with the position of the closing edge on the rotating wing element. In the event of a fire, in particular, when smoke makes it difficult to see, this is provided for in the event of an escape, so that safety is improved in emergency operations.

In this case, the at least one, in particular elongate, lighting means can be arranged on the door base or on an upper end edge of the revolving door. The position of the transition between the first light color and the second light color of the elongated light source corresponds to the position with which the wing element preferably slips over the door base with its main closing edge or is moved along or under the front edge when the turnstile rotates. This makes it easy to see where the entry areas of the revolving door are currently available. In particular in the event of a fire, this makes it easier to identify the wing element that may otherwise not be recognizable, which helps avoid collisions. The correspondence does not have to mean that it has to have exactly the same position, and it might be useful to move the position of the transition of the light color a little in front of or behind the wing element.

The object is thus also achieved by the method according to independent claim 10. Advantageous developments of the revolving door and the method are given in the description and in the figures. Features and details that are described in connection with the method according to the invention also apply in connection with the revolving door according to the invention and vice versa. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination. In particular, a revolving door is placed under protection with which the method according to the invention, in particular the method according to one of claims 10 to 15, can be carried out, as well as a method that is based on the invention revolving door according to the invention according to one of claims 1 to 9 can be performed.

Further measures improving the invention are shown in more detail below together with the description of preferred exemplary embodiments of the invention with reference to the figures. It shows:

• 1a and 1b a revolving door according to a first embodiment of the invention in two operating positions,
• 2a and 2 B a revolving door according to a second embodiment of the invention in two operating positions,
• 3a and 3b a revolving door according to a third embodiment of the invention in two operating positions,
• 4th a revolving door according to a fourth embodiment of the invention and
• 5 a revolving door according to a fifth embodiment of the invention.

the 1a and 1b show a revolving door 100 according to a first exemplary embodiment of the invention and each in an operating position. The revolving door 100 is essentially constructed in a conventional manner and comprises two drum walls 10 with a turnstile 12, which comprises four wing elements 11 in the example shown. As is known, the drum walls 10 enclose a passage area which is open on two sides.

By means of the wing element 11 of the turnstile 12 pivoting through the inlet opening 15, a front and a rear section of the inlet opening 15 are defined in relation to the wing element 11 in the passage area.

In the following, reference is always made to the wing element 11 pivoting horizontally through the inlet opening 15. Therefore, the reference number 17 relates to a main closing edge of this wing element 11. Provided that the turnstile 12 rotates this wing element 11 in the entrance area 15 to the right, this wing element 11 divides the entrance area 15 into a wing front area 14.1 between an opposing closing edge 19 of the right drum wall 10 and facing the wing element 11 the wing element 11, which gradually decreases in size from a maximum passage width when the turnstile 12 is turned, and a wing rear area 14.2 between a rear edge 18 of the left drum wall 10 facing the wing element 11 and the wing element 11, which moves gradually when the turnstile 12 is turned after again enlarged to the maximum passage width.

The revolving door 100 has a ceiling-side termination in the form of an upper ceiling above the turnstile 12. The upper cover has at least one front edge 14 in or on which a control 23 and sensors 21 for monitoring the closing edge and sensors 22 for person recognition are arranged. The controller 23 can also be held at any other location, e.g. in an external control column or an external switch cabinet, which has the advantage of better accessibility.

The sensor 21 is set up to detect obstacles or persons or objects such as suitcases or the like if they are too close to the opposing closing edge 19 of the right drum wall 10.

In the simplest case, the sensors 22, 22 are used to detect the presence of persons and preferably animals and / or objects in order to activate the drive of the revolving door 100 if necessary.

In the exemplary embodiment shown, a lighting means 16 is arranged along the opposing closing edge 19. The lighting means 16 is set up to shine in two colors, namely, for example, in green or red. The controller 23 controls the lighting means 16 to light up green as long as the wing element 11 is still far enough away from the opposing closing edge 19 ( 1a) . If the main closing edge 17 of the wing element 11 comes too close to the opposing closing edge 19, the luminous color changes to red to signal that the front wing area 14.1 has become so small that it can no longer be entered without danger, as in FIG 1b shown. If a distance is not reached from which there is a risk of entrapment, the lighting means 16 preferably flashes red. Once the wing element 11 has reached the opposing closing edge 19, there is consequently no longer any risk of being trapped, and the lighting means 16 is switched off or switched to green for the subsequent wing element 11, so that the entire process is repeated.

the 2a and 2 B show a revolving door 100 according to a second exemplary embodiment of the invention, each also in an operating position. The operating positions correspond to those of 1a (Wing element 11 far enough away from the opposing closing edge 19) and from 1b (Wing element 11 too close to the opposing closing edge 19).

In this embodiment, not only the opposing closing edge 19 but also the Main closing edge 17 of each wing element 11 has a lighting means 16. The controller 23 preferably controls the lighting means 16 on the wing elements 11, which are located within a respective inlet opening 15.

According to 2a The front wing element 11 gradually enlarges the rear wing area 14.2 and at the same time reduces the front wing area 14.1. As long as the distance between the main closing edge 17 of this wing element 11 and the rear edge 18 of the left drum wall 10 is so small that the wing rear area 14.2 cannot be safely entered without, for example, triggering a safety reaction of the revolving door 100, the illuminant 16 on this wing element 11 lights up yellow, for example shown with cross-hatching of the illuminant 16 on the main closing edge 17. Since the distance between this main closing edge 17 and the opposing closing edge 19 of the right drum wall 10 is sufficiently large, i.e. the front wing area 14.1 can be entered without any problems, the illuminant 16 lights up green on this opposing closing edge 19, shown as an example with right hatching of the illuminant 16.

It is also conceivable that the lighting means 16 on the end face of the wing element 11 lights up permanently or at least always when it is in the passage area, yellow, and a collision between the pedestrian and wing element 11 can also be prevented so that a periodic switchover does not occur is provided so as not to confuse a walker.

If the distance between this main closing edge 17 and the rear edge 18 of the left drum wall 10 has become sufficiently large that the wing rear area 14.2 can be safely entered, and this wing element 11 has not yet reached the right drum wall 10, the luminous color of the illuminant 16 on this wing element 11 changes, for example too green. If the distance between this main closing edge 17 and the opposing closing edge 19 of the right drum wall 10 is so small that the front wing area 14.1 can no longer be safely entered, the illuminant 16 on this opposing closing edge 19 changes to red, as in FIG 2 B shown, see cross-hatching or dotted bar of the illuminant 16.

If this distance becomes so small that there is a risk of entrapment, provision can be made for both lighting means 16 on the wing element 11 and on the right drum wall 10 to light up red or to flash. However, it is also conceivable that this counter-closing edge 19 changes to yellow when the distance is too small and only lights up or flashes red when there is a risk of trapping. For the sake of simplicity, it can also be sufficient to avoid too many color changes in order not to confuse the walker so that, for example, only a green walkway area is displayed when it is actually walkable.

This process is repeated cyclically for the wing element 11 subsequently moved into the inlet opening 15. Alternatively, it is provided that the illuminant 16 on the wing element 11 lights up permanently yellow in order to signal the presence of the wing element 11 in the inlet opening 15 or its movement. The illuminant 16 on the wing element 11 consequently has a purely indicative function.

the 3a and 3b each show a revolving door 100 according to a third exemplary embodiment of the invention, again in two operating positions.

According to this embodiment, the rear edge 18 of the left drum wall 10 and the opposing closing edge 19 of the right drum wall 10 each have a lighting means 16. Each wing element 11 has a lighting element 16 on its main closing edge 17, not designated here, with two separately controllable lighting sections 16c, 16d, which can shine in different colors. A lighting means 16 is also preferably located on the front edge 14 in the area of its outer edge of the upper ceiling facing the turnstile 12, which has two sections 16a, 16b of variable length parallel to the floor 13 that can be illuminated with different colors.

The lighting means 16 of the left drum wall 10 and the lighting sections 16a, 16c frame the rear wing area 14.2 from above, and the lighting means 16 of the right drum wall 10 and the lighting sections 16b, 16d frame the front wing area 14.1.

As long as the distance between the main closing edge 17 with the lighting sections 16a, 16b and the rear edge 18 of the left drum wall 10 is so small that the wing rear area 14.2 cannot be safely entered, the lighting means 16 of the left drum wall 10 and the lighting sections 16a, 16c glow red. Since the distance between this main closing edge 17 and the opposing closing edge 19 of the right drum wall 10 is sufficiently large, the lighting means 16 of the right drum wall 10 and the lighting sections 16b, 16d light up green.

If the distance between the main closing edge 17 with the luminous sections 16c, 16d and the rear edge 18 of the left drum wall 10 has become sufficiently large that the wing rear area 14.2 can be safely entered, and this wing element 11 has not yet reached the right drum wall 10, the luminous color of the luminous means 16 of the left drum wall 10 and the luminous sections 16a, 16c changes to green, as in FIG 3b shown. If the distance between this main closing edge 17 and the opposing closing edge 19 of the right drum wall 10 is so small that the front wing area 14.1 cannot be safely entered, the luminous color of the illuminant 16 of the right drum wall 10 and the luminous sections 16b, 16d changes to red, as is also shown in FIG 3b shown. If this distance becomes so small that the rotary movement of the turnstile has to be slowed down or stopped or if there is even a risk of entrapment, it can be provided that the lighting means 16 of the right drum wall 10 and the lighting sections 16b, 16d flash red. Instead of the scenario glowing red and flashing red, yellow lights and red lights can be provided accordingly.

Between the luminous sections 16a, 16b there is a color border 20, which can be implemented, for example, by means of a non-luminous luminous element such as an LED, which is designed in particular as a line emitter. The color border 20 can be designed to wander with the main closing edge 17 of the wing element 11 located in the inlet opening 15. In order to achieve this, the lighting means 16 has a plurality of lighting elements on the front edge 14, which are controlled by the controller 23 depending on the position of the turnstile 12 to light up in the respective color provided.

4th shows a revolving door according to a fourth embodiment of the invention. In contrast to 3 the luminous sections 16c, 16d and the luminous means 16 are absent on the drum walls 10. The control of the luminous sections 16a, 16b is preferably the same 3 .

5 shows a revolving door according to a fifth embodiment of the invention. In contrast to 4th Light sections 16a, 16b are not provided in or on the front edge 14 but in the door bottom 13. The activation of the luminous sections 16a, 16b preferably in turn compensates for the method 3 . This exemplary embodiment has the advantage that people moving on the floor due to fire or smoke, for example, can safely find and pass through the revolving door if it is provided as an escape route door.

The embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs. All of the features and / or advantages arising from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential to the invention both individually and in a wide variety of combinations.

The light elements 16 or light sections 16a, 16b that can be arranged on the drum walls 10, the front edge 14 and in the base 13 can also be formed in the area of the entry opening (not designated) of the revolving doors 100 shown pointing backwards in the figures.

The lighting sections 16a-16d and the lighting means 16 of the exemplary embodiments can be provided individually or combined with one another in any form. For example, the revolving door 100 according to FIG 3 lighting sections 16a, 16b also provided in the floor 13 according to FIG 5 which can consist, for example, of a number of LED point emitters or of a line emitter, for example of so-called light strips.

As a result, the invention creates a possibility of simplifying the accessibility of a revolving door and making it safer in the event of a fire. The public and private areas and especially sensitive areas such as old people's homes, hospitals and kindergartens are ideal locations. In addition, the intuitively easy to grasp light scenarios are particularly well suited for persons requiring special protection, who are not familiar with the use of the door, who need additional protection due to a handicap or who cannot assess the residual risks of a machine.

The colors of the lighting sections 16a - 16d and the lighting means 16 are described above and are arbitrarily represented by differing surfaces of the lighting sections 16a - 16d and the lighting means 16 such as left or right hatching, cross hatching or by dotted surfaces, the surface structure of the lighting sections 16a - 16d and the lighting means 16 should not be assigned a fixed color and these are only used for differentiation.
