Description

The present invention relates to a door assembly having a door leaf which is rotatably received in a door frame with Türbändem about a door axis having at least one parallel to the door axis extending side profile and to which the door hinges are arranged, wherein a door drive is provided, which is provided with the door leaf driving is in operative connection.

Door arrangements with a door leaf, which is rotatably received in a door frame via door hinges, are well known. Such door frames usually consist of a band-side and a lock-side side profile, the two side profiles are connected to an upper spar with each other. The door leaf is often hingedly received with two or more Türbändem on one of the two side profiles, so that the door leaf between a closed position and an open position can be moved.

In order to provide an automatic movement of the door leaf, door drives are known which have a base body which is attached either to the door leaf or the upper spar of the door frame. Other mounting options are given by walls in which the door assembly is introduced. From the main body usually extends an articulated arm, which forms the connection to the door leaf. Such door drives are visible from the outside, so that it is desirable to use door drives that are not directly attached to the outside of the door assembly.

Furthermore, door drives are known which are accommodated either in the ceiling or in the floor of the building in which the door arrangement is introduced. To accommodate the door drive in the floor area an installation space must be created, which regularly requires about 60 mm depth. Consequently, there are minimum requirements, for example, to a screed height to integrate the door drive in the floor of the building. Depending on the nature of the building floor, the possibility of integrating the door drive is not always required. Same difficulties arise in the integration of the door drives in the ceiling of the room in which the door assembly is integrated. Again Raumerfordemisse be fulfilled in order to integrate the door drive in a manner not visible. Also, the integration of the door drives in the wall in which the door assembly is introduced, results in significant problems.

It is therefore the object of the present invention to provide a door assembly with a door drive, which overcomes the problems of the aforementioned prior art and allows improved integration of the door drive in an invisible manner.

This object is achieved on the basis of a door assembly according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that the door drive is elongated in the direction of a drive axis, which runs parallel to the door axis of rotation, wherein the side profile has a cavity in which the door drive is received.

The invention is based on the idea that the side profile is designed with a cavity which is sufficiently large to accommodate the door drive. Provided is the side profile for education the cavity to which the door leaf with the door hinges is rotatably or pivotally received. The door assembly can be installed according to any situation, for example in a building wall, in a mobile partition that consists of a frame construction or in a wall that runs freely in a room without ceiling connection. The cavity within the side profile may also be formed between the side profile and the wall in which the door assembly is inserted. However, particularly suitable are side profiles, which are designed as aluminum extruded sections and already have production due to a cavity to accommodate the door drive.

The door drive is designed to be better integrated into the side profile in the direction of a drive axis elongated, so that the door drive has a high overall level of slimming and integration in the also elongated side profile is facilitated. The arrangement of side profile and integrated door drive according to the invention can thus be assembled ready made at the manufacturer of the door assembly, so that only a connection cable is led out of the side profile. As a result, a door assembly is provided with a door drive, which allows any installation situations and the door drive from the outside of the door assembly is not visible. Consequently, there are no space problems to integrate the door drive either on the door leaf, on the door frame or as an invisible door drive in the ceiling or in the floor.

According to a development of the door arrangement, this can be designed as a security door. For this purpose, a trained about the door axis of rotation rotary column is provided, wherein the side profile adjacent to the rotary column. As a result, the formation of pinch edges is avoided, since no door gap in the region of the door hinges arises, which increases when opening the door leaf and decreases again when closing. The door axis of rotation can either be formed integrally with the door leaf, so that this rotates with the opening and closing movement of the door leaf, wherein the rotary column can also be made in one piece with the side profile. In both embodiments, no expanding or decreasing door gap is formed because the door leaf rotates only about the outer periphery of the door pivot.

The drive axis of the door drive and the door axis of rotation are at a distance from each other, so that an operative connection is required to connect the output of the door drive with the door leaf to transmit torque. For this purpose, a transmission connection is provided, which can be carried out in various ways. On the one hand there is the possibility of a chain drive connection, whereby a connection by means of a toothed belt or a gear arrangement is possible.

Advantageously, the door drive has a longitudinally extending in the direction of the drive axis base plate on which the components of the door drive are arranged. The door drive can be fully assembled before installation in the side profile, wherein the various components of the door drive are applied to the base plate. Subsequently, the base plate can be connected either on the inside in the side profile or on an adjacent wall or other part of the building. The connection of the door drive within the side profile can be done via rubber elements, wherein further sound insulation material can be introduced into the side profile to run the door drive as quietly as possible.

The components of the door drive concern at least one controller, a motor, a transmission and a mechanical energy storage. The door drive further comprises a drive shaft which acts to drive the transmission connection, wherein the drive shaft comprises a coupling which allows a rotational angle adjustment for adjusting the door leaf. The motor is preferably designed as a DC motor, wherein the transmission can be designed as a planetary gear. Both the motor and the planetary gear can thus have a round cross-sectional shape to be adapted to the cavity of the side profile. The individual components are applied along the drive axis of the door drive in a sequential arrangement on the base plate in order to minimize the lateral dimensions of the door drive.

The mechanical energy storage is designed in the manner of a spring force accumulator, which is tensioned with an opening movement of the door leaf, so that a closing movement of the door leaf can be performed by relaxing the spring force accumulator. The spring energy storage can be arranged between the output and the planetary gear.

For receiving the door assembly, a ceiling mount and a bottom bearing are provided, which are arranged in the door axis of rotation and allow anchoring of the door assembly between the floor and the ceiling of a room. The bearing assemblies are particularly required for retrofitting the door assembly in a room, unless the door assembly is integrated over the door frame itself in the building wall.

In order to release the door assembly from the ceiling mount and the floor storage, a bearing clutch is provided, which is disposed either adjacent to the ceiling mount or to the floor storage. Consequently, when removing the door leaf or the complete door assembly, the ceiling bearing and the bottom bearing need not be removed from the anchorage, as at least one removal of the door leaf is made possible by simply loosening the bearing coupling.

The door operator may further comprise a rotary encoder to provide information about the opening and closing state of the door leaf. Due to the transmission connection between the drive shaft of the door drive and the door leaf, the rotary encoder can also be integrated in the door drive itself, with an arrangement of the electrical rotary encoder at the end of the motor is possible. The electric rotary encoder can be connected to the control of the door drive, in addition to the information of the opening or closing state of the door leaf to provide an end stop of the drive in the open position or possibly also in the closed position.

According to the embodiment of the door assembly as a security door, the gap between the side profile and the rotary column can be kept so small that, for example, the fingers of small children can not get into this gap. The gap can be made smaller than 8 mm, preferably smaller than 6 mm and particularly preferably smaller than 4 mm. The size of the gap does not change with the opening and closing movement of the door leaf, since the rotary column performs only a rotational movement and either the side profile adjacent to a rotating door pivot column or the door leaf at a dormant rotary column only to the surface of the rotary column and the gap width unchanged remains.

Further, measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to FIGS.

The door frame is formed from a first left side profile 4 and a right side opposite arranged side profile 22, wherein the two side profiles are connected to an upper spar 21 on the upper side. On the left side of the door frame, a door leaf 2 is rotatably received on the side profile 4, wherein the door leaf 2 is rotatable about the door axis of rotation 3. The side profile 4 is slightly wider and has a cavity 7, in which according to the invention a door drive 5 is added. The cavity 7 is shown cut to illustrate the door drive 5 in the upper area. The door drive 5 is mounted within the side profile 4 and extends along a drive axis 6. The drive shaft 6 is spaced parallel to the door axis of rotation 3, wherein for bridging the distance between the door leaf 2 and the door drive 5, a transmission connection is provided to the drive movement of the Door drive 5 to transfer to the door leaf 2.

The door leaf 2 has a rotary column 8, which extends around the door pivot axis 3 around. The rotary column 8 is connected to the door leaf 2 or designed in one piece with this, so that during a pivoting movement of the door leaf 2 between an open position and the closed position, a rotational movement of the rotary column 8 takes place. The rotary column 8 has at least in the direction of the side profile 4 has a round cross-section, wherein the side profile 4 adjacent to the rotary column 8 except for a small gap. Thus, the formation of pinch edges is avoided, since in the area between the door leaf 2 and the side profile 4 is not increasing or decreasing gap arises while the door leaf 2 is opened or closed. Consequently, the door assembly 1 according to the embodiment in FIG. 1 designed as a security door.

FIG. 2 shows the area of the arrangement of the door drive 5 within the side profile 4 in an enlarged view. The door frame is shown in fragmentary form only in the area of the side profile 4 and the upper spar 21. It can be seen that when opening the door leaf 2, the rotary column 8 only performs a rotation about the door axis of rotation 3, wherein this fully to the connection to the door leaf 2 itself has a round cross-section.

From the more detailed view of the door drive 5 it can be seen that it initially has a base plate 11, on which all the door drive 5 forming components are applied. The base plate 11 can be introduced after completion of the door drive 5 in the side profile 4 and screwed to it. The components of the door drive 5 relate to at least one controller 12, a motor 13, a gear 14 and a mechanical energy storage 15. End of the motor 13, an electronic rotary encoder 20 is arranged to sense the rotational position of the door panel 2. In this way, the controller 12 information can be provided at what angle the door leaf 2 is relative to the door frame. The controller 12 of the door drive 5 can be connected to a safety device of the building, in which the door assembly is introduced. Thus, for example, via the rotary encoder 20 by the controller information to be supplied to a central safety device, whether situation-dependent, the door leaf 2 is held in an open position or in a closed position. Furthermore, the rotary encoder 20 may be part of an active control device for controlling the opening and closing movement of the door leaf 2, provided that the door assembly 1 is designed as an automatic door with passage detection.

The mechanical energy storage 15 may be designed in the form of a spring force accumulator, so that in the opening movement, the energy is provided by the motor 13 both for opening the door leaf 2 and for tensioning the spring force memory, so that the door leaf, 2 for the closing movement only by the mechanical energy storage 15 is set in motion. Due to the arrangement, in particular a spring energy store in the form of a torsion spring is suitable.

In the FIG. 3 an enlarged view of the door drive 5 in operative connection with the door leaf 2 is shown. To illustrate the transmission connection between the door pivot axis 3 and the drive axle 6, the side profile 4 is shown in the cut state, wherein the transverse member 21 extends on the upper side adjacent to the side profile 4. Between the door drive 5 and the door pivot axis 3, a chain drive connection 9 is shown to transmit the rotational movement between the drive shaft 16 of the door drive 5 and the door leaf 2. The chain drive connection 9 is housed above the rotary column 8, wherein between the side profile 4 and the door leaf 2, a holder 23 is arranged to provide a reinforced connection between the door panel 2 and the side profile 4 ready. Between the drive shaft 16 of the door drive 5 and the chain drive connection 9, a coupling 17 is provided to make an adjustment between the rotational position of the drive shaft 16 and the rotational position of the door panel 2. Consequently, an adjustment of the door leaf 2 with respect to the closed position and the open position can be made via the coupling 17.

To secure the door assembly, both a floor bearing and a ceiling support 18 are provided to place the door assembly between the floor and ceiling of a room or building. The ceiling bearing 18 has a plate-like shape with a plurality of screw elements to firmly anchor the bearing with the ceiling of the room. In order to create a possibility, the door assembly from the admission of the Ceiling mount 18 to solve, a bearing clutch 19 is provided, which allows in the form of an axially displaceable sleeve, a bayonet fitting or the like, a release of the axis of rotation of the door leaf 2 from ceiling mount 18.

FIG. 4 shows by way of example a further embodiment of the transmission connection between the drive shaft 6 of the door drive and the door axis of rotation 3. The compound is exemplified as a toothed belt drive connection 10, wherein the side profile 4 extends beyond the length of the rotary column 8 to the height of the upper spar 21 to the Toothed belt drive connection 10 to blind. Thus, the cavity 7 is expanded within the side profile 4 by the space in which the toothed belt drive connection 10 is located. The door leaf 2 is shown in a wide open position, wherein it is also clear that the rotary column 8 is designed to be round throughout, so that only a small and consistent gap between the side profile 4 and the rotary column 8 is formed.

The invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. In particular, the transmission connection can also be designed as a gear drive connection, so that on the drive axle 6 of the door drive 5, a smaller and on the door axis of rotation 3, a larger gear is placed, each meshing with each other. Further, according to the arrangement of the clutch 17 may be provided an overload clutch, so that the door drive 5 can be limited in terms of the provided drive torque, the door leaf 2 should be blocked in the movement between the closed position and the open position. In particular, the door drive 5 can also be arranged only laterally adjacent to the side profile 4, provided that sufficient space between a wall and the side profile 4 is present. Therefore, the present invention is not limited to a closed cavity within the side profile 4, since it may also be open at least in the direction of an adjacent wall.
