Description

The present invention relates to a revolving door with a drive unit which is drivingly connected to a turnstile of the revolving door, and wherein the revolving door can be set up in a building having a walk-in floor body.

STATE OF THE ART

From the DE 197 11 460 A1 a revolving door with a drive unit is known, which is drivingly connected to a turnstile of the revolving door. The drive unit is housed on a floor body of the building and drives the turnstile of the revolving door via a gearbox with a motor. The large physical dimensions of the motor and the transmission to form the drive unit require a special design of the turnstile with multiple wings, which form a central unit, and only on the wings swing wings can be hinged, for example made of glass. This creates a large required installation space for the drive unit, which finally also the entire installation space for the arrangement of the revolving door, for example, in the facade of the building is also significantly increased.

Basically, the goal is pursued, not or only minimally enter the drive unit in the bottom body on which the revolving door is built. In particular, in historical buildings that are listed, for example, the required structural intervention in the building is often undesirably high, so solutions must be found, despite a bottom-side arrangement of the drive unit to the drive the turnstile in the revolving door to minimize the engagement in particular in the bottom body of the building.

From the EP 2 072 737 A2 a car ignition door with a drive unit is known, which is drivingly connected to a turnstile of the revolving door, wherein the drive unit is mounted on the ceiling side. Such a design of a revolving door clarifies the required installation space for integration of the drive unit above the turnstile, which is often not feasible or desirable for structural and aesthetic reasons. Revolving doors of recent design often even have glass ceiling elements that do not allow an arrangement of a conventional drive unit on top of the turnstile of the revolving door.

DISCLOSURE OF THE INVENTION

The object of the invention is to propose a revolving door with a drive unit, which is set up in the revolving door, that the structural intervention in a building and in particular in a bottom body on which the revolving door is built, is minimal or avoided.

This object is achieved on the basis of a revolving door with a drive unit 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 drive unit is designed as electronically commutated Vielpolmotor and gearless with the turnstile is in operative connection, wherein the Vielpolmotor is set up in the revolving door, that it can be arranged above the top of the bottom body.

The invention is based on the idea to provide a revolving door with a drive unit which is arranged on the underside of the revolving door, which does not protrude into the bottom body of the building. The invention makes use of the execution of the drive unit as an electronically commutated Vielpolmotor to advantage, which can be made very flat, so that a space between the top of the body and the turnstile can be created, in which the Vielpolmotor can be accommodated. In this case, the turnstile does not necessarily have to be located above the poly pole motor, because, according to an advantageous embodiment variant, it can also be accommodated in the turnstile itself. In particular, by the gearless connection between the Vielpolmotor and the hub further space is saved, which makes an arrangement of Vielpolmotors above the top of the bottom body in the first place possible.

Thus, the drive unit can be executed by the use of a Vielpolmotors gearless, and the Vielpolmotor can be brought without the interposition of a gear in direct arrangement with the turnstile in connection. As a result, the rotating part of the Vielpolmotors on the same speed as the turnstile of the revolving door and the Vielpolmotor may have a drive axle, which coincides with the axis of rotation of the turnstile.

Vielpolmotoren are also known under the name of the torque motors and basically have arranged on a circular path coil elements that form a coil ring and also arranged on a circular path magnetic elements facing, for example, on the inside, outside or axially opposite, so that a high-pole, high-torque direct drive is formed.

With particular advantage, the ratio of height to diameter of the essentially round, flat-shaped basic structure of the electronically commutated poly pole motor can have a value of at least 1: 3, preferably at least 1: 4, more preferably at least 1: 5 and most preferably from 1 : 8 and more. The ratio of height to diameter results from the parallel distance of the disc-shaped or pot-shaped stator part to the disk-shaped or cup-shaped rotor part of the Vielpolmotors to the diameter of the stator and / or the rotor part. Due to the fact that the coil elements and the magnetic elements can be arranged between the stator part and the rotor part, only the ratios of height to diameter of up to 1: 8 and more can be achieved, and it has been shown that even basic structures of multi-pole motors drive can be used for revolving doors, which can reach a ratio of height to diameter of more than 1:12.

In the present case, a disk-shaped shape is a flat cylinder in which the diameter is several times greater than the height. For example, the Vielpolmotor have a diameter of about 500 mm and a height of about 40 mm. Furthermore, the feature of a disc-shaped shape is also given when a Vielpolmotor primary disk-shaped shape is deliberately redesigned to another similar shape. For example, a flat, polygonal stump enclose the per se round stator or rotor part or for example, the stator or the rotor part has a deviating from a plate shape, non-circular shape, such as a flat, square cube. Such a transformation can be carried out by enclosing the rotor part or the stator part with a correspondingly shaped housing or by a corresponding transformation of the coil cores.

The multi-pole motor may comprise a disc-shaped or pot-shaped stator part, which can be arranged on the bottom body, and wherein the Vielpolmotor has a disc-shaped or cup-shaped rotor part which is arranged plane-parallel to the stator and drivingly connected to the turnstile of the revolving door. For this purpose, the turnstile may have a plurality of rotary blades, for example, two, three, four or more rotary blades, which are in particular individually connected to the rotor part of the Vielpolmotors. The inventive direct arrangement of the rotary wing on the rotor part of the Vielpolmotors eliminates the need for a shaft or other means of connection between an output element of the drive unit and the turnstile. In particular, no output shaft is required, so that no further increase in the necessary installation space of the drive unit is the result.

According to a first embodiment of the arrangement of the drive unit in the revolving door can be defined by the rotating hub a rotary cylinder, the Vielpolmotor is introduced in particular the bottom side in the rotary cylinder. The arrangement of the Vielpolmotors within the rotary cylinder on the bottom side of the rotary cylinder no separate space between the Vielpolmotor and the top of the bottom body is required. In particular, the multi-pole motor does not need to be recessed into the floor body, and the turnstile does not have to end up at a distance from the top of the floor body, which would result in an unnecessary gap.

The embodiment of integrating the polypoemotor within the rotary cylinder of the turnstile is made possible, in particular, by the fact that the rotary vanes comprise frame profiles which are also involved in the formation of the rotary cylinder and in particular define the outer dimensions of the rotary cylinder. The frame profiles can be on be cup-shaped rotor part of the Vielpolmotors be connected, such that the height of the Vielpolmotors at least partially coincides with the height of the particular bottom-side frame profiles of the rotary wing. The Vielpolmotor can form a flat cylinder, in particular with a cup shape, which may be located concentric to the axis of rotation on the underside of the hub, the cup-shaped Vielpolmotor can be visible to a viewer who passes, for example, the turnstile. From the overhead assembly inevitably visible to a viewer arrangement of Vielpolmotors, but this forms a pot shape, so the Vielpolmotor can be unobtrusively integrated in the lower frame cross profile of the turnstile.

For example, the pot-shaped rotor part may have a pot shell portion, wherein the frame profiles can be connected outside of the pot shell portion. For example, the frame profiles can be screwed on the outside of the pot casing section or the Topfmantelabsohnitt or the entire rotor is part of the construction of the turnstile , With particular advantage, the Vielpolmotor thereby have a height corresponding to the profile height of the frame profiles. This results in a harmonious, aesthetically high-quality overall picture of the turnstile with the multi-pole motor integrated into it.

The above-described first embodiment of the revolving door thus describes a drive unit which is formed by a multi-pole motor integrated into the turnstile of the revolving door. In particular, the Vielpolmotor on the bottom side of the turnstile is integrated in this. According to a further advantageous embodiment of the revolving door of Vielpolmotor can be arranged between the turnstile and the bottom body, in particular so that the Vielpolmotor is arranged below the definable by the rotating hub rotation cylinder. Particularly flat multi-pole motors can have heights of less than 60 mm. For example, if a multi-pole motor has such a flat configuration, the stator part of the multi-pole motor can be connected to the planar upper side of the base body, and the rotor part accommodates the turnstile of the revolving door extending over it. For this purpose, the disk-shaped or cup-shaped rotor part may have a preferably planely designed outer surface pointing in particular in the direction of the rotary blades, and the rotary blades may be arranged on the outer surface.

If revolving doors are set up on the upper side of a floor element in a building, ground supports are frequently provided, which are formed for example by treadmills. These may have a height that may already correspond, for example, up to 50% of the overall height of the Vielpolmotors. Furthermore, it is necessary to attach to the bottom frame profiles of the rotary wing sensor strips, which may also have a height, and together with the foot mats, a gap between the bottom frame profiles and the top of the bottom body can already be bridged, which is determined by the height of the Vielpolmotors.

According to an advantageous development of the electronically commutated Vielpolmotors the rotor part can be rotatably received on the stator by means of wenigstes a bearing element about a drive axis, resulting in a bearing of the turnstile on Vielpolmotor. The bearing can be dimensioned such that at least the mass the turnstile and in particular additional ceiling loads that act from the ceiling element via a ceiling mount on the turnstile and finally also on the Vielpolmotor can be supported. The bearing may preferably be designed as a thrust bearing, wherein a further bearing for supporting the rotor part may be provided on the stator, which is designed as a radial bearing. The turnstile and ceiling loads can thus be transferred via the thrust bearing through the Vielpolmotor in the bottom body, and a further, separate storage of the turnstile is not required at least on the underside of the revolving door, so that the Vielpolmotor forms the bottom side bearing of the hub.

The revolving door may have a frame in which the turnstile is rotatably received. At least one control and / or interface module can be arranged on the frame, wherein an electrical line, in particular comprising at least one rotary feedthrough, can be guided through the turnstile, by which the control and / or interface module is electrically connected to the multi-pole motor.

The rotary feedthrough may preferably be arranged integrated in Vielpolmotor. As a result, the advantage is achieved that the electrical line does not have to be routed through the bottom body of the building, so that no intervention in the bottom body must be made for this purpose.

Finally, the Vielpolmotor can still have a position or angle encoder, this is used for commutation and determination of angular positions and the rotational speed of the turnstile.
