Description

Title: revolving door

description

The invention relates to a revolving door with at least one night closing wing which runs concentrically at least to a drum wall, which rather slides or rolls on a guide rail arranged on the ceiling construction or attachments thereof and can be moved relative to the drum wall by means of a flexible endless traction means.

British patent application 2 052 615 A has disclosed a motor-operated locking device by means of which the inner exit can be blocked in order to prevent armed persons from entering the interior of a building. The motor-driven movability of the closing device is effected by a motor arranged on the frame of the revolving door, which drives a revolving chain, which in turn is coupled to a centrally running, movable wall section. Only one wall section can be coupled to the circulating chain, i.e. it is not possible to connect two night closing wings that can be moved in opposite directions to the chain. In addition to the chain, several pulleys are required, which means a corresponding construction effort and a deterioration in efficiency.

From DE 39 28 911 C2 an opening / closing mechanism for curved sliding doors is also known, in which an endless belt with two horizontal strands lying side by side is used. The endless belt is placed around the drive pulley and the driven pulley, with the two door leaves being firmly connected to the endless belt at the same time. When the drive motor is activated, the two door leaves are slidably actuated in the opposite direction along a left or right guide rail. This type of drive is complex because a large number of guide and deflection rollers is required. When using a toothed belt, it is also necessary to turn the toothed belt by 180 ° in order to be able to guide it on the corresponding guide rollers. Furthermore,

RESERVATION COPY The efficiency of the drive is enhanced by the frictional resistance of the guide rails and rollers

Based on the state of the art according to British patent application 2 052 612 A, the invention is based on the object of improving a carousel structure of the type mentioned at the outset in such a way that, when using an endless traction means, a night end wing can optionally be connected to the traction means, or alternatively - two counter-rotating night-end wing can be used. Alternatively, different traction devices, such as roller chains or toothed belts, should be able to be used without the need for special additional deflection rollers or the traction device having to be turned through 180 °. A structurally simple and reliable solution is sought, in which only one drive (drive roller) and a corresponding deflection roller are required to operate the traction mechanism

The invention achieves the stated object with the teaching according to claim 1

Due to the forced guidance of the endless traction means in overlying strands, the traction means can be guided on the drive side with a drive roller with a horizontal axis and on the reverse side over a deflection roller mounted in the same way, with a chain - preferably a roller chain - a toothed belt or the like being used as the traction means The drive means cannot be turned, i.e. it does not have to be turned through 180 °. The positive guidance ensures that the traction means is reliably guided both horizontally and vertically in the running rail, without the need for additional roller guides the guide formed by the running track is designed in accordance with the curvature of the night closing plane and runs centrally to it, so that regardless of the use of one or two night closing wings, only a single running track is required, which corresponds to the construction effort reduced

Further features of the invention are characterized by the subclaims According to claim 2, between the strands of the flexible traction means at least one carriage connected to the night-ending wing is positively guided in the running rail, the running carriage being connected to the night-ending wing via at least one connecting member (claim 3).

The positive guidance of the carriage in the running rail provides a safe and reliable connection between the flexible traction means and the night-end wing, i.e. the flexible traction means is already relieved of all forces acting on the night final wing by the positively guided sliding carriage, especially since the sliding carriage - for example in an articulated design - is guided with a sufficient longitudinal extension in the slide rail and is provided, for example, with two connecting members for connection to the night closing wing can (claim 4).

Preferably, an axis is provided which encompasses the carriage, the connecting member and the night end wing, serves to support a support and guide roller (claim 5), so that all forces acting on the night end wing can be deposited on the ceiling construction via the support and guide roller and the The carriage itself and the flexible traction device only have to absorb the tractive forces for moving the night cover. For this purpose, the carriage is connected to a strand of the flexible traction device via a driver (claim 6).

A particularly advantageous embodiment of the invention results from the features of claim 7; according to this, two oppositely movable night end wings are provided, each night end wing being assigned at least one adjustable carriage and one night end wing being connected to the lower run and the other night end wing being connected to the upper run of the flexible traction means. This advantageous embodiment of the invention results from the teaching given in claim 1, namely the arrangement of the flexible traction means in superimposed strands of the running rail, which is designed according to claim 8 as a box profile, the box profile having a penetration slot for the connecting member, so that the running rail mirror-symmetric to its horizontal axis of symmetry (claim 9)

According to claims 10 and 11, the flexible traction device can advantageously be designed as a roller chain, wear inserts being arranged in the running rail and the roller chain being positively guided in the locking inserts. Alternatively, however, a toothed belt can also be used (claim 12)

When using the teaching according to the invention according to claim 1, there is also the advantage that the flexible traction means are driven by a motor with an associated self-locking gear (claim 13), so that an additional closing mechanism for the night closure can be dispensed with

As mentioned above, the operation of the flexible traction means only requires a motorized drive acting on a drive roller at one free end of the running rail and a deflection roller at the other free end of the running rail. According to claim 14, it is necessary to achieve reliable guidance of the traction means in the assigned positive guidance advantageous if the deflection roller is provided with a tensioning device

In an embodiment of the invention, it is further proposed to design the drive for the flexible traction device such that it is switched off when a force limitation arranged on the main closing edges of the night closing wing (s) responds, or drives the flexible traction device in opposite directions in the sense of an opening process of the night closing wing (s)

The invention is explained in more detail below with the aid of a possible schematically illustrated exemplary embodiment. It shows

Figure 1 is a plan view of the carousel door in a schematic representation

FIG. 2 shows a view in arrow direction II-II according to FIG. 1

Figure 3 shows the section III-III of Figure 1 in an enlarged view FIG. 4 shows a view in arrow direction IV according to FIG. 3

In FIG. 1, 1 denotes a revolving door, which essentially consists of door leaves 5 which can be rotated about an axis 6 and which are arranged within the drum walls 3, 3 'which delimit them. Two night closing wings 4, 4' are arranged concentrically with the drum walls 3, 3 ' 8, which means flexible traction means guided in the running rail 7. Each night closing wing 4, 4 'is assigned two connecting links 11, one end of the night closing wing 4 or 4' and the other end of a running carriage 10 or 10 'are connected, the carriage 10 or 10' being positively guided within the running rail 7 (FIG. 3). FIG. 1 furthermore shows that the flexible traction means 8 is driven by means of a drive 16 with an associated drive roller 17 and at the other end via a drive device provided with a tensioning device 18 Deflection roller 19 is deflected

According to FIGS. 1 and 2, two night end wings 4, 4 'are provided, with (see FIG. 2) the night end wing 4 via a driver 14, which is only indicated, to the lower run 9' of the flexible traction means 8 and the night end wing 4 'via the driver 14 is connected to the upper run 9 of the flexible traction means 8. When the drive 16 and traction means circulating in the direction of arrow 27 are actuated, the night closing wings 4, 4 ′ move towards one another in the direction of arrow 28, ie the night closing is closed. The main closing edges 29 are not Force limits shown in more detail, by means of which the drive is switched off or reversed

As can be seen in FIGS. 3 and 4, in the exemplary embodiment a bracket 22 is fastened on the ceiling structure 2, to which the running rail 7, which runs concentrically to the drum wall 3 ', is connected via a screw connection 26. The running rail 7 preferably consists of an aluminum alloy with a through-slot 20 running rail 7 wear inserts 15 are arranged, in which the flexible traction device 8 designed as a roller chain is positively guided. The roller chain is guided by force arranged stub axles 23 which slide in corresponding groove-like recesses of the wear inserts 15, so that the chain is positively guided both in the vertical and in the horizontal direction. The wear inserts 15 are preferably made of a suitable plastic. It can be seen that the chain runs 9, 9 'are arranged vertically one above the other. The upper run 9 of the roller chain is connected to the carriage 10 by means of a screw connection 25 via a driver 14. An axis denoted by 13 encompasses both the slide 10 and the connecting member 11, which is U-shaped in cross section, and the night closure wing 4 ', a supporting and guide roller 12 being mounted on the axle 13 in the region of the connecting member 11, which is supported on a guide rail 21 resting on the ceiling structure 2. The weight of the night end wing 4 'and all the forces acting on the night end wing 4' are thus transmitted to the ceiling structure 2 without the traveling carriage 10 or the flexible traction means 8 being loaded thereby. The support flanges of the running rail 7, designated 24, serve exclusively to guide the running carriage 10.

In FIG. 4 it is shown that two carrying and guide rollers are assigned to a running carriage 10 '. The carriage 10 'is here seen in one piece over its length; it can be shaped in accordance with the curvature of the running rail 7, that is to say it can be arcuate, or it can be divided over its length into a plurality of sliding carriage sections which are flexibly connected to one another.
