Description

The invention relates to a swing door with a preferably motor-driven swing wing with a holding device, which stabilizes the swing wing in its zero position, i.e. closed position. The holding device serves to secure the wing against unwanted, uncontrolled swinging movement from or beyond the zero position.

Swing doors with electric motor drives are known to have a holding device consisting of a brake that interacts with the drive. The brake interacts directly with the output shaft of the motor. It must be switched on to keep the door in the zero position. The structure and control of this holding device is relatively complicated, and the construction volume is relatively large.

For swing doors with swing door closers, holding devices are known that are integrated into the door closer's gear. With these devices, the stabilization of the zero position is achieved by a locking body engaging in a locking recess in the cam disk of the door closer's gear. These devices are also relatively complicated.

The invention is based on the object of creating a swing door of the type mentioned at the beginning, in which the holding device is simply constructed and can be used in conjunction with various drive systems.

This object is achieved by the invention in that the holding device is arranged so as to engage between the frame and the swing sash, whereby it locks the swing sash in its zero position, i.e. closed position, and can be overridden by turning the swing sash in the opening direction by hand or via the drive motor.

The holding device can be arranged in the upper area of the door, preferably on the upper horizontal border of the door, away from the pivot axis of the swing leaf.

The holding device can have a movable first member which is arranged on the frame or on the swing sash and, in the zero position of the swing sash, interacts with a second member of the holding device which is arranged on the swing sash or on the frame.

In this case, the first member can preferably be designed as an armature and the second member in particular as an electromagnet, e.g. a lifting magnet. In other embodiments, the first member can be designed as a spring-loaded locking member and/or friction member and the second member can have a locking receptacle or a friction surface.

In preferred embodiments, the holding device can also be combined with a lock for locking the swing wing, preferably in a common structural unit.

In the following, embodiments are explained in conjunction with the figures.

a representation corresponding to Figure 3 of a modified embodiment of the zero position holding device;

Figure- 5

a representation corresponding to Figures 3 and 4 of a further embodiment of the zero position holding device with additional lock, section plane along line V - V in Figure 4.

The embodiments in the figures are single-leaf swing doors with electromechanical drive. The drive device 1 is housed above the swing door leaf 2, preferably in or on the underside of the upper horizontal frame beam 3. The swing door leaf 2 is electromechanically driven in the opening and closing direction via the drive device 1. The pivot axis of the swing leaf 2 is designated by 4.

To open, the drive can be controlled via external control devices (not shown). Alternatively, control can be carried out by briefly pressing the wing 2 by hand in the opening direction.

In Figure 1, the door leaf 2 is shown in its closed position, the so-called zero position. If a person approaches the door from the outside - from side A - the drive is controlled via the external control device or by pressing on the door leaf so that the leaf 2 opens inwards. The leaf rotates clockwise. In the opposite case, if a person approaches from the inside - from side B - the drive is controlled in the same way to open outwards. The leaf rotates anti-clockwise.

After opening, the wing 2 then remains in the maximum open position, e.g. 90 degrees, for a predetermined open time or until the person has passed through the door. The wing then also closes using a motor and is secured in the zero position shown by a holding device 5 arranged in the upper horizontal area.

The locking takes place as soon as the leaf 2 has reached the zero position and is released when the door is opened. The holding device 5 is arranged in the upper horizontal door area at a distance from the pivot axis 4. The structure and function of this device is described in more detail below.

The drive unit 1 consists of a DC motor 13 with planetary gear 14 and a bevel gear set 15 connected to it with an output shaft 16 and also of a control device 17.

The control device ^ 7 is preferably housed in a separate box which is arranged next to or above the modules 13 or 15. The modules 13, 14, 15, 17 are fastened to a mounting plate 18 screwed to the frame beam 3. The holding device 5 is arranged at the end of the mounting plate 18 which is remote from the pivot axis.

The output shaft 16 and door leaf 2 are connected via a door rail screwed to the upper edge of the door leaf. As can be seen in Figure 2, the output shaft 16 engages the door rail 20 attached to the leaf 2 in a form-fitting and rotationally fixed manner. The shaft 16 is inserted into a front-side recess 21 of the door rail and is clamped in place via front-side clamping pieces 22 using screws 23.

The holding device 5, which, as previously mentioned, serves to fix the sash 2 in the zero position, consists of an electromagnet 25 arranged in the upper horizontal beam 3 and an armature 26 arranged in the upper horizontal frame of the sash 2 (Figure 3). The armature 26 can be moved vertically on a bearing pin 27 screwed into the sash frame between a retracted position and an upwardly deflected position. A locking pin 28 screwed radially into the armature engages in a constriction 29 in the head of the bearing pin 27.

In the retracted position, the lower edge of the armature 26 rests on a radial collar 30 of the bearing pin. The upward-facing surface of the armature lies slightly above the upper edge of the vane and at a distance from the underside of the electromagnet 25.

As soon as the leaf 2 comes to the zero position when closing, the electromagnet 25 is switched on via a zero position sensor attached to the door and the armature 26 is thereby attracted by the electromagnet into the deflected position. The upward-facing surface of the armature 26 forms the contact surface that rests on the active surface on the underside of the electromagnet 25. The leaf 2 is thus held in the zero position. The contact surface of the armature 26 and the active surface of the electromagnet 25 are flat and aligned in the direction of movement of the door leaf. They are aligned with one another when the leaf is in the zero position.

When opening, if the door is pushed in the opening direction by the drive or if the door is pushed in the opening direction by hand, the holding force of the electromagnet is overridden.

The armature 26 carries out a shearing movement towards the electromagnet 25 by the contact surface of the armature sliding over the effective surface of the electromagnet. The armature remains in its deflected position until it leaves the effective range of the electromagnet. It then moves into its retracted position under the effect of its weight or under the effect of a return spring acting on the armature.

The electromagnet 25 switches off when the leaf 2 reaches a predetermined opening position or after automatic control. The control can be carried out via a door position sensor. The electromagnet 25 is only switched on again when the leaf reaches the zero position. When the electromagnet 25 is switched on, the armature 26 is finally attracted again so that its contact surface rests on the effective surface of the electromagnet.

To adjust the height of the armature 26, the bearing pin 27 is screwed more or less far into the threaded hole 3 V in the casement frame. The position of the armature is adjusted so that when the armature is pushed in, a gap remains between the contact surface of the armature and the effective surface of the electromagnet, which gap corresponds to the lifting height.

In the embodiment in Figure 4, a purely mechanical holding device 45 is used. It has a structural unit with a locking ball or locking roller 46, which is also installed in the upper frame beam 3. The ball 46 is pushed downwards by a compression spring 47. For this purpose, the structural unit has a housing 48 which is open at the bottom and in which the spring 47 is accommodated, which is supported on the one hand on the inner housing cover and on the other hand on a stamp 49 guided in the housing. The locking ball 46 is mounted on the stamp 49.

In the zero position of the door leaf 2, the locking ball 46 engages in a locking recess 43 on the upper horizontal edge of the leaf.

When the door is opened, the locking ball 47 is deflected upwards, i.e. into the housing, over the slanted surfaces of the recess 43. The compression spring 47 is compressed in the process. The locking ball 46 finally comes out of the recess 43 and then rolls on the slanted outer edge 44 of the upper edge of the door leaf and reaches its deflected position as soon as it is out of the door leaf. This process takes place when the door is opened in either direction, due to the symmetry of the locking receptacle 43 and outer edges 44.

When closing the door, the process takes place in the opposite direction to when opening it. The locking ball 46 is first pressed upwards over the slanted outer edge 44 and then finally locks into the recess 43 when the door leaf is in the zero position.

In the embodiment shown in Figure 5, the mechanical locking device 45 from Figure 4 is combined with an electromagnetic lock 50. For this purpose, a lifting magnet 51 is mounted on the housing 48, which interacts with a locking hook 52, which locks the locking ball 46 in its locking position in the receptacle 43. The door leaf 2 is thus locked in its closed position.

The locking hook 52 engages in the position shown in Figure 5

locking position in a notch 53 in the plunger 49. In the

In the release position not shown, the locking hook 52 is disengaged.

To control the locking hook 52, it is connected to the armature of the lifting magnet 51 via a rigid bow-shaped connection as in Figure 5 or alternatively via a two-armed lever.

The lifting magnet 51 can be connected in such a way that the locking hook 52 is held in the release position when the current is switched on and moves into the locking position when the current is switched off* A return spring acting on the armature 54 can serve to move it into the locking position.

Alternatively, the lifting magnet 51 can also be connected in such a way that the locking hook 52 is in the locking position when the current is switched on and the release position when the current is switched off.

In modified versions, an electric motor can be used instead of the lifting magnet 51, which moves the blocking flap 52.

Instead of the ball locking device 45, an electromagnetic holding device of Figures 2 - 3 can also be used and can interact with a lock 50 with a lifting magnet 51 or an electromagnet. A locking hook 52 or the like can also be provided here, which in this case interacts with the armature 26 of the holding device, to lock the armature. Alternatively, however, a locking pin controlled by the lifting magnet 51 can also pass through the armature 26 and engage directly as a locking bolt in a locking plate on the door leaf 2. To connect the locking bolt to the armature of the lifting magnet 51, a stationary two-armed lever can be provided, which converts the horizontal movement of the armature into the vertical movement of the locking bolt.
