DESCRIPTION

Door arrangement, in particular security door with an integrated door drive

The present invention relates to a door arrangement with a door leaf that is housed in a door frame rotatably around a door pivot axis by door hinges, a pivot column configured around the axis of door twist

The door arrangements of the type in question are well known in the state of the art. The door frame is composed of at least two lateral profiles that run in a vertical direction, the door hinges being arranged in one of the two lateral profiles for the pivotal articulated housing of the door leaf. The two side profiles are connected to each other by an upper beam on the upper side of the door frame. However, the door frame may also be composed of other means, known, for example, in the case of mobile partition walls and the like.

Document DE3121136 discloses a drive for a tilting door.

The door leaf is rotatably housed around a door rotation axis, a rotation column is provided which is designed as a single piece with the door leaf and rotates together with the opening and closing movement of the door. Door leaf or is disposed in an uncoupled manner of rotation in the door frame or is a component of the door leaf. If the turning column is configured as a component of the door leaf, the side profile of the door frame is so close to the turning column that only a small opening is created, there is no danger of crushing by simply rotating movement of the spin column as a result of the movement of the door leaf. If the turning column is designed as a stationary component of the door frame, at least the door leaf adjoins the turning column such that only a small opening also arises between the turning column and the door leaf also the danger of crushing. Doors of this type are known as security doors, because by means of the turning column as a transition zone between the door leaf and the door frame there is no opening that is enlarged and in particular that is reduced, when the leaf Door opens and closes again.

The turning column has a diameter greater than the thickness of the door leaf. Depending on the embodiment of the door frame, the turning column can have approximately a diameter that coincides with the width of the side profiles that form the door frame. If the pivot column is designed as a stationary column, it can also be designed in the form of a single piece with the side profile, to which the door leaf is attached with the door hinges.

To operate the door leaf, door drives are known which have a base body, from which a lever arm extends to create an active connection between the door leaf and the door frame. The base body of the door drive is fixed on the upper side of the door leaf or door frame. This requires mostly a constructive space that, conditioned by the situation, is not always available. A door drive is also desired that is not visible directly on the outer side of the door arrangement, in particular in case of modern door arrangements and in case of a design as a security door. Known variants of door drives envisage integrating the door drive into the ceiling or floor of the room or building, in which the door arrangement is installed. In this sense, however, constructive premises are required, because the mounting space, for example, in the floor area of the door arrangement, requires at least 60 mm depth. These premises are basically not met, with another disadvantage in the costly installation and loading of the door drive due to dirt.

Therefore, the objective of the present invention is to configure a door arrangement as a security door and also integrate a door drive not visible in the security door.

This objective is achieved from a door arrangement according to the preamble of claim 1 in combination with the features. Advantageous variants of the invention appear in the dependent claims.

The invention includes the technical instruction that the door drive is housed in the pivot column of the door arrangement, the door drive interacting with the door leaf in a motor manner.

In the case of a turning column, formed by at least a first half and a second half, the halves are joined together by means of joining elements to configure a tubular structure, rotating the halves together with the rotary movement of the door leaf.

Alternatively, the turning column is composed of tubular elements successively located in the direction of the door turning axis. Preferably, four tubular elements can be provided superimposed vertically around the axis of rotation of the door, the bearing being arranged between the tubular elements

Fixed and / or free bearing. The tubular elements can be screwed or fastened together in a longitudinal direction, the respective door leaf bearings can be housed as door hinges in the dividing planes of the tubular elements. A tubular element can be provided in the area of the door drive so that at least the entire door drive is housed therein.

The invention starts from a security door with a pivot column that is perfected to accommodate a door drive. It is also proposed a door drive designed so that it can be inserted in the pivot column of the security door. The door drive has a drive shaft that matches the door rotation axis. The turning column can be designed as a stationary turning column and not turning with the door leaf, a turning column also being suitable to accommodate the door drive, which is configured as a single piece with the door leaf or at least it is designed so that it is attached to it and rotates together with the rotary movement of the door leaf. In this regard, the door drive is designed with a high slenderness ratio, extending it longitudinally in the direction of the drive shaft. Therefore, it is possible to mount the door drive on the pivot column, without designing it with a diameter that is too large.

According to a possible turning column, it borders the door frame to configure a security door, which has at least one side profile, in which the door leaf is installed with the door hinges. This prevents the formation of crush edges and the door arrangement is configured as a security door. An opening smaller than 8 mm, preferably less than 6 mm and in particular preferably less than 4 mm, extends between the lateral profile and the column of rotation. In this way the danger of crushing is effectively avoided, because the selected opening is so small that it prevents, for example, that the children fastened from the side profile do not crush their fingers when the door leaf makes a closing movement.

The door pivot axis and the drive shaft advantageously form a common rotation axis, a roof bearing being provided, as well as a floor bearing concentrically with respect to the rotation axis for mounting the door arrangement between a roof and a floor. The door frame, formed by the two lateral profiles, as well as the upper beam, can be additionally anchored in a wall of a building or in the ceiling, as well as in the floor of the room, in which the arrangement of door. The roof and floor bearings also absorb, however, the turning torques generated by the opening and closing movement of the door leaf. The door drive is housed in a rotatable manner in the column of rotation between the ceiling bearing and the floor bearing to transmit the rotation pairs. Therefore, the door drive does not perform a rotational movement, so that the pivot column can rotate around the door drive, if it is attached to the door leaf and is designed as a simultaneous pivot door column. The electrical connection cable for the door drive can be passed through the floor bearing, so that the manufacturer can completely construct the door arrangement with the door drive and it is only necessary to install it at the mounting location between the floor and the ceiling of the room.

A variant of the door arrangement, according to the invention, has door hinges that are configured as annular bearings and extend in the form of at least one fixed bearing and a free bearing around the axis of rotation of the door. The fixed bearing is characterized in that it is connected to the output of the door drive so that it transmits the torque, in order to create an active connection between the door drive and the door leaf. The free bearing, on the other hand, has only the function of a simple door hinge and is preferably installed on the lower side of the door leaf.

However, the active connection between the door drive and the door leaf can also be carried out by means of the turning column, which represents only another constructive embodiment. The pivot column can be rotatably housed by the door drive or also between the ceiling bearing and the ground bearing, the output of the gate drive on the inner side being connected to the pivot column. If the door drive is activated, the turning column makes a rotating movement around the door turning axis or around the driving axis. If the door leaf is connected correspondingly to the pivot column, the rotary movement is transmitted thereto to the door leaf and it can be moved between a closed position and an open position. It is also possible that the output of the door drive is rotatably connected to the ceiling bearing and that the entire door drive is rotated during operation. If it is attached to the turning column, a rotating movement is also transmitted to the turning column.

The halves can be designed as continuous cast aluminum profiles or as plastic profiles, the second half can also be designed in the form of a single piece with a door leaf component. The joining elements to join the two halves can be simple screw connections. In case of maintenance or replacement of the door drive, it is possible to separate the bolted joints and remove the rear half that is on the side opposite the door leaf. It may also be provided that the halves do not extend over the entire height of the door arrangement, but are subdivided several times. Accordingly, window-shaped holes can be created by disassembling parts of the halves to control, for example, manually the door drive.

The door drive is composed of several components that can be mounted by way of example on a support body or that are successively mounted, also advantageously, in the direction of the drive shaft to create a longitudinal extension of the door drive. The door drive comprises at least one control, a motor, a gear and a mechanical energy accumulator. The gear transforms the speed of rotation of the motor to the small speed of rotation of the output of the door drive, the gear being preferably designed as a planetary gear. The mechanical energy accumulator can be an elastic force accumulator, in which during the opening movement of the door leaf by means of the motor and the gear a mechanical force is stored that can be used in a known manner to close the door leaf , without the electrical operation of the motor.

The door drive may also have an electric rotary encoder to provide information on the opening and closing state of the door leaf. The electric rotary encoders can also be configured as decoders and can be installed on the end side of the motor. This allows information on the open and closed state of the door leaf to be measured, and the speed of rotation of the door leaf can also be transmitted as information to the control of the door drive. According to a variant of the door drive, two motors can also be provided for the drive in order to provide an enlarged torque of the door leaf, the motors being configured as direct current motors and the gear being configured as a planetary gear. Particularly in the case of motors of only small diameter for integration in the turning column it can be advantageous to arrange two motors one behind the other to provide a sufficiently large turning torque due to the small diameters of the motors. The design of the gear as a planetary gear also enables a slender construction, the respective diameters of the components being preferably fitted together.

An advantageous embodiment of the door arrangement comprises a bearing coupling disposed between the ceiling bearing and the door drive. This makes it possible to disassemble the roof bearing door arrangement and, therefore, also the ground bearing by separating the bearing coupling. The bearing coupling can be designed as a simple sleeve or as a bayonet closure, the roof bearing can be separated from the door drive and in particular the entire arrangement of the pivot column by a simple rotary, sliding or helical movement.

Similar to the embodiment of the pivot column with two halves, also in the embodiment of the pivot column by means of tubular elements, it is provided that the door arrangement is designed as a security door by colliding the door leaf with the tubular elements, except an opening. In this embodiment, the opening may also be less than 8 mm, preferably less than 6 mm and in particular less than 4 mm. The pivoting column in the form of the tubular elements rests during the movement of the door leaf, the door leaf rotating around the round rotation column. Therefore, an opening is not generated here either, which is enlarged when the door leaf is opened and reduced during the closing movement, to avoid crushing.

Other measures that improve the invention are explained in detail below, together with the description of a preferred embodiment of the invention by means of the figures.

door drive 5 as a purely mechanical door drive, configured only in combination with an elastic force accumulator to automatically execute the closing movement of the door leaf 2. The door drive 5 extends in a longitudinal direction along a drive shaft 6. The slenderness ratio of the door drive 5 in the direction of the drive shaft 6 is selected so that the door drive 5 can be integrated into the inner side of the turning column 4. According to this example of embodiment, the rotation column 4 rotates together with the movement of the door leaf 2, because the rotation column 4 is connected in a resistant manner to the door leaf 2. The side profile 7 borders the rotation column 4 such that only a small opening is formed that does not vary during the opening and closing movement of the door leaf 2. Consequently, the formation of crushing edges, thus providing the arrangement of door 1 as a security door.

Figure 2 shows a detailed view of the arrangement of the door leaf 2 in combination with the turning column 4. The turning column 4 is composed of a base body 28, around which a first half 12 and a second half 13. The second half 13 is designed as a component of the door leaf 2, this constituting, for example, a part of the door leaf frame 2. The two halves 12 and 13 extend in each case approximately 180 ° around base body 28 of the pivot column 4 and screwed together for assembly. The door drive 5 is integrated in the upper area of the base body 28, the radial dimensions of the door drive 5 corresponding to the dimensions of the base body 28 so that halves 12 and 13 can be joined together to form a round pivot column 4. On the upper side of the door a ceiling bearing 8 is arranged and on the lower side of the door a floor bearing 9 is disposed that are fixedly connected with the base body 28. Bearing arrangements 8 and 9 make it possible to anchor the door arrangement 1 between the ceiling and the floor of a room or building, in which the door arrangement 1 is installed. For this purpose only a threaded joint is required, without having that provide a space in the ceiling or floor to integrate the door drive 5.

The housing of the door leaf 2 in the rotation column 4 is carried out by means of a fixed bearing 10, as well as a free bearing 11. The fixed bearing 10 is connected to the output of the door drive 5 to transmit the torque of rotation, so that the door drive 5 can transmit the rotary movement to the door leaf 2. The free bearing 11 represents only a pivotal articulated joint of the door leaf 2 with the base body 28 of the turning column 4 As a result of the integration of the door drive 5 in the turning column 4, both the door turning axis 3 and the driving shaft 6 are located inside each other, so that a very high level of integration is created of the door arrangement 1.

Figure 3 shows in a perspective view a partial section of the arrangement formed by the first and second half 12 and 13 for the configuration of the pivot column 4. The two halves 12 and 13 are joined together by connecting elements 14 in the form of screws. Halves 12 and 13 may be designed, for example, as continuous casting aluminum profiles or as plastic profiles. The second half 13 has a profiled geometry that can be a component of the door leaf frame.

Figure 4 shows another embodiment of the arrangement of the pivot column 4 and the door leaf 2. According to this exemplary embodiment, the pivot column 4 can be formed by several tubular elements 22 a

25. These are arranged successively in the direction of the door pivot axis 3 or the drive shaft 6 of the door drive 5. The door drive 5 is integrated in the tubular section 23 shown in the disassembled state for a representation detailed. The door drive 5 has a control 15, a motor 16, a gear 17, a mechanical energy accumulator 18, as well as an electric rotary encoder 19. To increase the torque, another motor 20 is provided mounted on the end side of the first motor 16. The individual components, which form the door drive 5, are arranged one behind the other in the direction of the drive shaft 6 and joined together. Accordingly, the door drive 5 can be integrated into the tubular element 23. The door hinges of the door leaf 2 are formed by a fixed bearing 10, as well as a free bearing 11, the fixed bearing 10 being configured to transmit the turning torque of the door drive 5 to the door leaf 2. The free bearing 11 is supported on the tubular element 25 between the door leaf 2 and the turning column 4 only to form an articulated joint. On the lower side of the tubular element 25 a floor bearing 9 is provided for joining the pivot column 4 to the floor of the room. On the upper side, the pivot column 4 has a roof bearing 8 which, like the floor bearing 9, extends concentrically with respect to the axis of rotation of the door 3. Between the door drive 5 and the bearing From the roof 8, a bearing coupling 21 is provided to separate the pivot column 4 from the anchor if necessary. The tubular element 22 preferably here forms a liner on the bearing coupling 21, which can be removed from the outer side of the door arrangement 1. This exemplary embodiment proposes another door arrangement that represents a very compact and robust embodiment. The fixed bearing 10 is screwed on the door leaf 2, the gear 17 being fixedly screwed on the upper end of the tubular element 23. The door drive 5 has a receiving shaft, connected with the fixed bearing 10 by means of an adjustment spring.

The invention is not limited in its embodiment to the preferred embodiment shown above.
