Description

Brief indication: Automatic sliding and revolving door system with break-out device

The invention generally relates to an automatic sliding and revolving door device with break-out device, also known as "break-away", break-out "or anti-panic door device. Such devices are used in particular in situations where many people may be present , such as access doors to large stores or department stores, shopping centers, (office buildings, public buildings, etc.)

Automatic sliding and revolving door devices with break-out provision are known in the art. Such a device usually comprises two central sliding door wings, which are arranged slidably back and forth along a sliding track with the aid of a drive to open and close the sliding door wings. The drive is controlled by means of detectors, which detect the presence / absence of people within a certain detection area in the vicinity of the sliding door wings. The sliding door wings are furthermore rotatably arranged around a vertical axis. A suitable locking system keeps the sliding door wings in normal position during use, with rotation about the vertical axis being prevented. In addition to the sliding door wings, also referred to as "mobile" panels, side wings (also referred to as fixed panels) are often arranged on either side thereof, which wings are also arranged rotatably about a vertical axis and are kept closed under normal circumstances with the aid of suitable locks.

In the event of an emergency, the locks can be broken by manually pushing the door forcefully or supported with the help of a push bar or the like. After unlocking, the user pushes the wing in question further open until there is sufficient passage space to pass. Each wing must be manually unlocked and opened. This impedes a smooth passage because passers-by do not always know that all wings can be opened and are therefore inclined to use only an already opened wing. Furthermore, since the sliding door leaves can be unlocked at any position in the sliding track, the free passage (escape route) cannot be maximal, for example when a sliding door leaf is not completely pushed aside. This is often reinforced because the opening angle of the wings is not fixed, so that they take, for example, a non-parallel open position or position that is not substantially transverse to the door opening.

The present invention has the broad object of providing a door device of the type discussed above, wherein it is possible to guarantee a smooth flow of passers-by in the event of an emergency situation.

A further object of the invention is to ensure the maximum opening width or free passage.

Yet another object is to provide such a door device, which can also be operated in cases where the door device itself is difficult to access.

To that end, the door device according to the invention comprises at least one sliding wing, which is arranged so as to be movable, a sliding drive for sliding the sliding wing back and forth along a path between an opened and a closed sliding position, wherein the sliding wing is further rotatable about a first vertical axis. is arranged, a first lock for preventing rotation of the sliding wing about the first vertical axis, at least one side wing parallel to the sliding wing, which is arranged rotatably about a second vertical axis, and a second lock for preventing rotation of the sliding wing side wing about the second vertical axis, and at least one operating member for unlocking the first and second locks, wherein the at least one sliding wing and the at least one side wing are each provided with a rotary drive for turning the respective wing on unlocking, and wherein the operating member comprises means vo or remotely unlocking the first and second locks.

The door device according to the invention is defined in claim 1 and comprises at least one sliding wing and at least one side wing. An embodiment of the door device according to the invention comprises two central sliding wings and on either side parallel to the sliding wings a side wing. The at least one sliding wing is guided back and forth with the aid of a drive over a linear sliding path between a closed sliding position and an opened sliding position. The open sliding position can be adjustable, for example a winter position and a summer position with different opening widths. Both the sliding wings and the side wings are provided with a provision for opening outwards in the event of an emergency.

To this end, the wings are rotatably arranged about a vertical axis. The wings are locked against unintended rotation with the help of locks. In the door device according to the invention, after the release of the lock, the turning movement is effected by its own rotary drive for each leaf, preferably a mechanical drive, so that even in the event of a power failure, the doors open automatically when necessary. To release the rotary lock of the mobile and fixed panels, the operating means comprises unlocking means, which can be operated remotely.

In contrast to the known devices, in which the rotary locking of the wings must be manually broken and the wings subsequently pushed open manually, the opening in the device according to the invention takes place under the influence of a rotary drive after the remote locking of the locking. This makes the door device according to the invention suitable for many applications, for which applications different safety requirements can be imposed by the government. Thus, it is possible to design the door device according to the invention as a conventional anti-panic door device, wherein, however, the unlocking means are provided in the vicinity of the door device, for example an emergency button operation or glass break switch, which, in addition to unlocking the locks, also actuate the rotary actuators or release. A conventional push rod can also be used on the mobile panels, wherein the push rod does not provide mechanical unlocking and operation, but emits a signal, thereby breaking the locking and activating the rotary drives. In the event of an emergency situation, the rotation lock of all wings is released by operating the release means, whereafter the rotation drive of each wing causes the wing in question to open in the escape direction and therefore does not have to be opened manually manually. The unlocking means can also, or in addition to the situation described above, be provided at a central counter, for example a reception, which is advantageously permanently occupied. After all, an emergency situation will often be reported to a central counter. In the event of a fire, if the door device according to the invention is connected to the fire brigade central, the fire brigade itself can operate the door device, for example for allowing smoke to be controlled (controlled).

It is noted that from US 6526695 B1 an anti-panic door device is known, which is provided with a damper which gives a controlled resistance to the turning movement when manually opening a rotatable sliding or side wing.

In order to reach the maximum width of the escape route, a control unit for controlling the sliding and rotating drives is provided, which is arranged such that the mobile panels move to an extreme open sliding position, such as with the aid of the sliding drive thereof or an additional non-moving drive. electric drive. The control unit is preferably arranged in such a way that the sliding movement of the mobile panels takes place prior to, more preferably at the same time as the rotating movement, in order to avoid the risk of passers-by getting jammed between an open side wing and an open side sliding wing moving towards it.

Examples of a suitable non-electric rotary drive for turning a wing include a tensioned spring, a hydraulic pump, reversing (door) closers. The rotary drive advantageously makes it possible to carry out the rotary movement at a controlled speed, as is the case with a hydraulic pump. The door device preferably also comprises limiting means for limiting the turning opening angle of the door leaves, more preferably a predetermined opening angle is fixed, advantageously about 90 °. Angle limiters, stops, springs and hydraulic pumps are suitable examples of this.

The locks include electromagnets. If desired, in addition to a connection to the regular electricity grid, the electromagnets are provided with an additional energy source that is not connected to the electricity grid, such as one or more batteries, in order to prevent the wings from opening on their own and thereby providing access for unwanted visitors.

The door device according to the invention can also be combined well with a (pass) control function with remote reading function. In a door device with a break-out device according to the prior art, such a check is limited to the passage of the sliding wings. Such a check can then be circumvented via the side wings that can be opened manually at any time. With the device according to the invention this is not possible when there is a central operation.

The invention is explained below with reference to the accompanying drawings, in which

FIG. 1 is a principle sketch of an embodiment of a door device according to the invention in a position during normal use;

The illustrated embodiment of a door device 10 comprises two central sliding wings 20 which are linearly slidable between a closed sliding position indicated by dotted line, wherein the edges 22 of the sliding wings 20 facing each other lie against each other and an open sliding position shown with a broken line, the sliding wings 20 are spaced apart. Linear movement between a closed position and an open position and vice versa is effected by a sliding drive (not shown in Figs. 1 and 2), which is usually mounted centrally above the sliding wings. On the outside of the sliding wings 20, side wings 24 are arranged which are closed during normal use.

FIG. 2 shows this embodiment in the open position after releasing the rotary lock of the sliding wings 20 and side wings 24. The side wings 24 are swung open in the direction of the escape route, usually outwards, around a vertical axis of rotation indicated by reference numeral 26. The sliding wings 20 are also swung open in the same direction as the side wings 24 around a vertical axis of rotation 28 and slid to their maximum open sliding position. As is clear from this figure, the free passage is maximum in this situation.

FIG. 3 shows an embodiment of a door device according to the invention in more detail. Parts 1 and 2 are designated by the same reference numerals. A sliding wing 20 comprises a panel 30, usually made of a transparent material such as glass, which is mounted in a frame 32. The sliding wing 20 is slidably mounted in an upper guide 34 with the aid of one or more carriages 36. In this embodiment the carriages 36 are provided with a sliding beam 38 at the ends 37A, 37B. A vertical post 40 of frame 32 is rotatably arranged at its upper end about pivot axis 28 in end 37A of sliding bar 38. At the bottom, post 40 is slidably arranged in a bottom guide 42 and rotatable about said pivot axis 28. The carriages 36 are driven in the usual manner with the aid of a schematically shown sliding drive 44, which is arranged above the top conductor 34. On the inside of the top rail 46 of the frame 32 a hydraulic rotary drive 48 is arranged, which controls a push arm 50, one end of which is pivotally connected to the drive 48 and the other end is pivotally connected to the sliding beam 38 via conductor 51. A electromagnet 52 placed between sliding bar 38 and top rail 46 keeps the rotating frame 32 in the normal sliding position, ie in the same vertical plane as the sliding bar 38. The sliding drive 44 is controlled by means of presence sensors, such as an infrared safety sensor 49 (see fig. 1) on the inside and outside of the central sliding wings and / or photocells (not shown).

Apart from the sliding provision, the side wings 24 are rotatably arranged in a similar manner. A side wing 24 comprises a panel 50, usually made of a transparent material such as glass, mounted in a frame 52. Vertical post 54 is rotatably arranged about a vertical axis 26. Attached to the inside of top rail 56 is a rotary drive 58, here a hydraulic pump, the rotary arm 60 of which is pivotally connected to a conductor 61 on upper beam 62. A normally energized electromagnet 64 keeps the side wing 24 closed.

The wings are unlocked by switching off the power supply to the electromagnets 52 and 64. Fig. 3 schematically shows various options for this purpose, which can be used individually or in combinations thereof. A glass break switch 70 (see also Fig. 1) is provided on the inside of the building. Another possibility is a control button 72 at a central counter 74. Finally, a connection to an emergency service center 76 such as a fire station is shown, so that the wings can also be unlocked remotely.

Fig. 3 also shows a control and control unit 80 which, upon receipt of a signal that the electromagnets (should) be deactivated, takes over the control of the sliding wings (normally dependent on the aforementioned presence detectors) and the sliding wings to their extreme allows the open position to move, unlocks all locks and thereby puts the rotary actuators into operation.
