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-leaf passage door, in particular for security gates, with at least one main door leaf which is equipped with at least one folding leaf.

Such passage doors are known in a variety of designs. The locking mechanisms are e.g. Controlled via electronics so that after a person's access authorization has been checked, the door system is released, opened and then closed and locked again.

Such passage doors are complex to construct and are hardly suitable for retrofitting in a «normal» door opening, i.e. In order to implement such a solution, a relatively high effort would have to be expected.

It is therefore an object of the present invention to provide a passage door of the type defined in the introduction, which ensures perfect security with regard to the basic task and operation and which can be easily installed in any existing passage without any particular effort. At the same time, this should ensure faster passage through the lock if possible.

This object is achieved according to one of the claims.

The invention is subsequently explained, for example, using a drawing.

10 shows a further embodiment analogous to that according to FIGS. 6 to 8;

11 shows a construction of a double-leaf passage door corresponding to the structure of FIG. 10, analogous to that according to FIG. 9.

1 and 2 show purely schematically the structure of a passage door according to the invention in the closed state. Both the two-leaf passage door 27 of FIG. 1 and one-leaf

Passage door 28 according to FIG. 2 are shown in the closed state. Both are built into an existing door frame 1a, 1b, which defines the door opening. These versions of a passage door are suitable for retrofitting without having to make structural changes to existing structures.

The two passage doors shown in FIG. 1, which form the door system 27, each consist of a main door leaf 4a, 4b and an associated folding leaf 4c and 4d. The main door leaf and folding leaf are connected to one another for the purpose of synchronized movement in the manner explained later. The main door leaves 4a and 4b can be pivoted about fixed pivot axes 5 and 6, while at their ends they are connected to their folding leaves 4c and 4d via pivot axes 5 '.

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

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

If the pressure is from the inside out, i.e. the door system is opened from room 15 to room 16 onto folding wings 4c, 4d. The door system 27 is closed by actuating the folding wings 4c, 4d from the outside space 16. The folding wings move synchronously with the main wings.

The movement of the folding wings 4c, 4d is mechanically transmitted to the main wings 4a, 4b. The two main wings 4a, 4b can be connected to one another via levers and a push rod in such a way that the main wings open and close synchronously and can never be pivoted in the same direction (FIG. 5). This is e.g. explained in detail in CH-A (registration according to enclosure).

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

The door system 27 has the tendency to open in a passage direction from the interior 15 to the exterior space 16, thereby clearing the escape route, and the tendency to close in the reverse passage direction, which forms protection against vandalism and unauthorized access.

A single person can open or close the door system 27 from both sides.

Fig. 2 shows an analog door system 28, but only with double wing doors 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 people move from the inside 15 to the outside 16. The folding wings 4c, 4d are pressed in the direction of movement by the people. If the door system 27 is not locked securely, then

the force of the person pushing the door open.

Sketch 2:

The door system was opened by the force in the direction of movement of the person. The force transmission between the folding leaf and the main leaf transmits the force in the direction of movement of the person into a force in an opening direction of the door leaf. Due to the transmission ratio of the power transmission (1: 4), the force for opening the door is increased despite the shorter lever arm (1: 2). People pushing forward increase the pressure in the direction of movement - the door system must open wider.

Sketch 3:

The door system is largely open and the door system is opened further by the force in the direction of movement of the people from the inside out.

Sketch 4:

The door system is fully open. People can pass through 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 persons move from the outside 16 to the inside 15. The door system is pressed in the direction of closing by a spring system and in the event of a power failure.

Sketch 2:

The door system 27 is closed further by the force of the closing mechanism. The movement of the folding door leaves 4c, 4d runs in the direction of movement of the penetrating person. If the person exerts a force on the folding door leaves 4c, 4d in the direction of movement, this force is transmitted into a force in the closing direction of the door leaves by the force transmission between the folding door leaves 4c, 4d and the main door leaves 4a, 4b. Due to the transmission ratio of the power transmission (1: 4), the force for closing the door system is increased despite the shorter lever arm (1: 2). Pushing people increase the pressure in the direction of movement - the door system must close automatically.

Sketch 3:

The door system is largely closed. The door system is closed further by the force of the people in the direction of movement.

Sketch 4:

The door system is completely closed, e.g. mechanical, and locked. People can no longer pass through the door system.

5 shows a perspective view of the opened main door leaves 4a and 4b with the folding leaves 4c and 4d in a corresponding position. A basic possibility of synchronizing the main door leaf and the folding leaf in the opposite pivoting direction is made possible, for example, by the two levers 30 and an interposed push rod 31. Such synchronization is also possible by means of a crossed chain or corresponding measures.

The two door systems 27 and 28 discussed have conventional electronically controlled locking mechanisms (not shown) which can lock the door leaves in the closed or given partially opened position. However, in order not to block the entire opening and closing system in the event of a power failure, the measures discussed are intended to be carried out by human forces.

6 to 8 a possibility of coupling the folding wing to the main wing is shown schematically. 6 shows the open state of the passage door, FIG. 7 shows a middle state and FIG. 8 shows the closed state. The synchronous mechanical coupling of the main wing 4b with the folding wing 4d takes place via a load chain 19 which is suspended at two fixed points 20, 21, for example of the door frame. Main wings 4b and folding wings 4d are mechanically connected to one another via a chain wheel 18, which is arranged eccentrically to the pivot point 6 'of the folding wing 4d. The geometric locations 20, 21 of the fixed suspension of the load chain 19 are closed by the transmission ratio of the rotational movement between the main wing 4b and the folding wing 4d (1: 4), the effective diameter of the chain wheel 18 and the angle between “open” (FIG. 6) and “ »(Fig. 8). The chain wheel is mounted eccentrically to compensate for the length of the chain 19 during the movement between “open” and “closed”. If the main wing moves e.g. by 30 °, the folding wing rotates 120 ° relative to the main wing. This corresponds to a movement between the "open" and "closed" positions of the door system.

Fig. 9 shows a construction similar to Figs. 6 to 8, wherein a cross bar 35, 35 'is arranged on the main door leaves 4a and 4b, at the free ends of which there are two sprockets 36, 36' and 37, 37 ' are freely rotating. Each wing has a pair of fixed points 20, 21 or 20 ', 21' which are connected to one another by a chain 19, 19 'via the chain wheels 37, 37', 36, 36 'and 38, 38'.

By actuating the folding wings 4c and 4d, the remaining parts execute movements as can be seen in the central and closed positions in FIG. 9.

evident. Here the folding wing 4d is provided with an angle arm 40. In addition to the fixed point 6, a further fixed point 43 is provided, which is connected to further joints 41 via struts 42. When opening the door these struts lead

42 corresponding swivel movements, as can be seen from the central and the closed position.

Fig. 11 shows a similar construction as Fig. 10, but for a double-leaf passage door. Here the two main door fixed points 5 and 6 are stationary. Another fixed benchmark

43 is provided, while the articulation points 41 and the struts 42 connecting them change their position during the closing process of the passage door, as shown.

The connections of the door panels shown are made, depending on the given structural circumstances, by appropriate rails, as the explanations shown show.

The described, multi-leaf passage door according to the invention thus creates a closure that is basically locked, can be opened for a person identification system, ensures a controlled passage, enables or requires isolation and ensures the escape route.

In addition, fire protection regulations and other protection concerns can be met. What is particularly important is the retrofitting, which allows an optimal passage frequency of at least eight people per minute and is inexpensive with minimal structural changes despite isolation.
