Abstract

A controlled, multiple-wing passage door is used in particular person access locks. It has at least one main wing (4a, 4b) equipped with at least one folding wing (4c, 4d). The main wing (4a, 4b) is coupled so as to swivel, to the folding wing (4c, 4d), so that both wings move in different directions of rotation when they are actuated. The door (4a, 4b) formed by the main wing may be opened only into one (16) of the spaces (15, 16) which it separates, in particular outwardly. The rotation of the main wing and of the folding wing is synchronized to ensure that they reach their end positions when the folding wing is actively moved. This passage door has absolutely reliable function and operation. It may be built into any existing passages without problems and at no special cost. At the same time, it ensures a more rapid passage through the access lock.

Description

The present invention relates to a controlled, multi-wing Passage door, especially for security gates, with at least one articulated on a fixed pivot axis Main door wing, which with at least one folding wing is equipped, the folding wing over a swivel axis is pivotally connected to the main door wing in such a way that the both lying on top of each other when swiveling between two end positions open and unfolded relative to each other in the closed state in different synchronized Move directions of rotation.

Such passage doors are available in a wide variety of designs known. The locking mechanisms are e.g. about electronics controlled so that after checking the Authorization for passage of a person released the door system, opened and closed and locked again.

Such a controlled multi-leaf passage door, which with one or two main door leaves, each with one Folding wings are equipped and which the other aforementioned Having features is disclosed by DE-A-25 07 967.

Such passage doors are complex to construct and are suitable hardly for subsequent installation in a "normal" door opening, i.e. to realize such a solution would have to be relative high effort can be expected.

It is therefore an object of the present invention to provide a passage door of the kind defined at the beginning, which create a perfect security with regard to basic task and operation guaranteed and which without any special effort in every existing passage can be installed. At the same time if possible, a faster passage through the Lock can be guaranteed.

This object is achieved according to the characterizing part of claim 1 solved.

1 and 2 show the structure purely schematically a passage door according to the invention in the closed Status. Both the two-leaf passage door 27 of FIG. 1 as well as single-leaf passage door 28 2 are shown in the closed state. Both are in an existing door frame 1a, 1b, which determines the door opening, installed. These versions of a passage door are suitable for retrofitting, without any structural Changes made to existing structures Need to become.

The two passage doors shown in Fig. 1, which form the door system 27 consist of one each Main door leaf 4a, 4b and an associated folding leaf 4c and 4d. Main door wing and folding wing are for the purpose of synchronized movement in later explained Senses connected. The main door wing 4a and 4b are about locally fixed pivot axes 5 and 6 swiveling while at their ends over swivel axes 5 'connected to their folding wings 4c and 4d are.

When closed, these door systems separate 27 and 28 the interior 15 from the exterior 16.

As shown in Fig. 1, the two double doors form 4a / 4b and 4c / 4d a door system 27. The double wing doors are arranged so that by moving the folding wing 4c, 4d the door system closed or opened can be.

If the pressure is from the inside out, i.e. from Room 15 after room 16 on the folding wings 4c, 4d, the door system is opened. By pressing the Folding wing 4c, 4d from the outside space 16 becomes the door system 27 closed. The folding wings move in sync with the main wings.

The movement of the folding wings 4c, 4d is based on the Main wing 4a, 4b mechanically transmitted. The two Main wings 4a, 4b can be levered and a push rod so connected that the Open or close the main wing synchronously and never can be pivoted in the same direction (Fig. 5).

The double leaf system 27 can be equipped with a second door system form a lock room. The two door systems can be coupled mechanically.

The door system 27 has in a passage direction from Interior 15 to exterior 16 the tendency to open, with which she clears the escape route, and vice versa Direction of passage the tendency to close, what protection against vandalism and illicit Admission forms.

A single person can use the door system 27 of both Open or close pages.

Fig. 2 shows an analog door system 28, but only with double wing door 4b, 4d.

Fig. 3 shows the passage of people from the inside 15 to the outside 16 (escape from the inside to the outside with the door system closed).

Sketch 1:

Door system 27 is closed. The person or the People move from inside 15 to outside 16. The folding wings 4c, 4d by the people in Direction of movement pressed. Is the door system 27 not locked securely, so can by the force of the Person pushing the door open in the direction of movement.

Sketch 2:

By the force in the person's direction of movement the door system opened. By power transmission between the folding wing and main wing, the force in Direction of movement of the person in a force in a Transfer the opening direction of the door leaves. By the Power transmission ratio (1: 4) is the power despite the shorter lever arm (1: 2) reinforced to open the door. Pushing people increase the pressure in the direction of movement - the door system must forcibly open further.

Sketch 3:

The door system is largely open, and through that Force in the direction of movement of people from the inside the door system is opened further to the outside.

Sketch 4:

The door system is fully open. The people can pass the door system unhindered.

Fig. 4 shows the passage of people from the outside 16 to the inside 15 (protection against vandalism).

Sketch 1:

The door system 27 is open. The person or the people move from the outside 16 to the inside 15. The Door system becomes motorized and in the event of a power failure a spring system pressed towards the closing.

Sketch 2:

The power of the locking mechanism turns the door system 27 further closed. The movement of the folding door leaves 4c, 4d runs in the direction of movement of the intruding person. Practice the person in the direction of movement a force on the folding door leaves 4c, 4d, this force is transmitted through the transmission between Folding door leaf 4c, 4d and main door leaf 4a, 4b in one Transfer force in the closing direction of the door leaves. Through the transmission ratio of the power transmission (1: 4) is despite the shorter lever arm (1 : 2) increases the force to close the door system. Pushing people increase the pressure in the direction of movement - the door system must move forced to close.

Sketch 3:

The door system is largely closed. Through the Force applied by people in the direction of movement the door system is closed further.

Sketch 4:

The door system is completely closed, e.g. mechanically, and locked. People cannot use the door system more happen.

Fig. 5 shows a perspective view of the opened Main door leaves 4a and 4b with the folding leaves 4c and 4d in the appropriate position. A basic one Possibility of synchronization of the main door leaves and the folding wing in opposite directions Swing direction is, for example, by the two Lever 30 and an intermediate push rod 31 allows. Such synchronization is also with a crossed chain or equivalent Measures possible.

The two door systems 27 and 28 discussed point conventional electronically controlled locking mechanisms on (not shown) which the door wing in the closed or given partially open Can lock position. But in the event of a power failure the whole opening and closing system is not the measures discussed are to be blocked human forces feasible provided.

6 to 8 is a possibility of coupling of the folding wing to the main wing schematically shown. Fig. 6 shows the open state of the Passage door, FIG. 7 a middle state and FIG. 8 the closed state. The synchronous mechanical Coupling the main wing 4b with the folding wing 4d takes place via a load chain 19 connected to two fixed Points 20, 21, for example the door frame, hung is. Via a sprocket 18, the eccentric is arranged to the pivot point 6 'of the folding leaf 4d, are main wing 4b and folding wing 4d mechanically with each other connected. The geometric locations 20, 21 of the fixed suspension of the load chain 19 are by Gear ratio of the rotary movement between Main wing 4b and folding wing 4d (1: 4) the effective Diameter of the sprocket 18 and the angle α between "open" (Fig. 6) and "closed" (Fig. 8) certainly. For length compensation of the chain 19 at the That is the movement between "open" and "closed" Sprocket mounted eccentrically. If the moves Main wing e.g. the folding wing turns by 30 ° by 120 ° relative to the main wing. This corresponds to one Movement between the positions "open" and "closed" of the door system.

FIG. 9 shows a structure similar to FIGS. 6 to 8 Construction, with the main door wings 4a and 4b a cross bar 35, 35 'is arranged on the free ends are two sprockets 36, 36 'and 37, 37 'are located, which are freely rotating. To every wing belongs a fixed point pair 20, 21 or 20 ', 21', which by a chain 19, 19 'over the chain wheels 37, 37 ', 36, 36' and 38, 38 'are interconnected.

By operating the folding wings 4c and 4d other parts movements, as in the middle and the closed position of FIG. 9 can be seen.

10 is a single-leaf passage door in the open, semi-closed and closed position visible. Here is the folding wing 4d with an angle arm 40 provided. In addition to the fixed point 6 is a another fixed location 43 is provided, which over Struts 42 are connected to further joints 41. When the door is opened, these struts 42 lead accordingly Swivel movements from how this from the middle and the closing position can be seen.

Fig. 11 shows a construction similar to Fig. 10, however, for a double-leaf passage door. Here are the two main door fixed points 5 and 6 stationary. Another fixed benchmark 43 is provided while the hinge points 41 as well as them connecting struts 42 during the closing process the passage door change position as shown.

The shown connections of the door panels with each other takes place, depending on the given structural circumstances, by appropriate rails, such as those explained Show explanations.

The described multi-wing controlled according to the invention Passage door thus creates a conclusion, which is basically locked for one Personal identification system can be opened ensures a controlled passage, one Isolation enables or requires and the escape route guaranteed.

In addition, fire safety regulations and others Protection concerns are met. It is particularly important the subsequent installation, which with minimal structural changes despite isolation one optimal pass frequency of at least eight people allowed per minute and is inexpensive.
