DE2507967A1 - Folding leaf door with power-driven thrust element - performs simultaneous rotation and translates flow of force from drive to door leaf - Google Patents

Abstract

The present design uses a thrust element connected to the driving gear in such a way that the element performs a rotary movement around a joint and ensures that the force flow from the drive passes through the thrust element to the door leaf. The thrust element is pivoted in a joint (11) on the drive end and in a point (8) on the door end. The push or pull action from the drive is applied to a point (22) and a thrust element (1) describes a rotary movement around a point (11) enforcing the swivel movement of the door leaf around another point (1). A connecting element (g) performs a partly translatory and partly rotary movement induced by the rotary movement of a power-driven arm (h) rotates around a point (4).

Description

Rotary folding door (addition to P 13 14 224.0 and P 24 53 944.4) The invention relates to a hinged folding door with a firmly attached first wing and an on this hinged second wing as well as a power-operated drive and folding linkage, which one hinged to a stationary or relocatable Ånlen @ point Schubgli ed has, which in turn with a between the first and second wing arranged slider crank mechanism that folds the second wing by around 1800 during operation connected is.

Rotary folding doors of this type are known from main application P 18 14 224.0 and DOS 1 919 281 of the applicant; these famous gates work extremely well satisfactory and operationally reliable.

In practice it has been shown that it can be used in confined spaces in some skins it is difficult to accommodate the drive and folding linkage. This is especially true if there is no sufficient lateral during the construction planning Space has been provided to accommodate this linkage.

It is therefore an object of the invention to modify the folding doors of the initially mentioned type to improve.

According to the invention, this is the case with a rotary folding door mentioned at the beginning achieved in that the thrust member is connected to a drive device, which rotates the thrust member around its articulation point during operation, with the flow of force runs from the drive device via the push member to the gate leaves. Man thus receives a very space-saving structure.

An arrangement has proven to be particularly favorable, which is characterized by the fact that the thrust member with the rocker arm of a four-bar linkage Is rotatably connected, which rocker via a coupling of the four-bar linkage with a crank of the four-bar linkage that can be driven in rotation by the drive device connected is. Such an arrangement enables z. B., the drive motor together its crank on the side close to the folding door or in the middle above or below to arrange the gor is therefore extremely space-saving. Nevertheless, there is a Extremely uniform and therefore surprisingly calm sequence of movements, whereby one proceeds with particular advantage that the coupling and crank in the open and in the The closed position of the folding gate is roughly in line with each other to start and at the end of the closing or opening process, only a low speed in each case the wing, in the area between the beginning and the end, on the other hand, a relatively high speed, to achieve. Such a sequence of movements is especially desirable because of it in the event of a response that is usually provided on the front edges of the gate leaves Sensors, the so-called touch strips, control the movement of the gate in particular can be stopped immediately if the gate is already almost closed, and so on to safely prevent jamming due to the movement of the gate.

Further details and advantageous developments of the invention result from those described below and shown in the drawing Embodiments. 1 shows a first exemplary embodiment of an inventive Rotary folding door, and FIG. 2 shows a second exemplary embodiment in the form of one with and 3 a central drive provided rotary folding door according to the invention.

Parts that are the same or function in the same way are used in the individual figures each designated by the same reference numerals and usually only described once.

Fig. 1 shows a first embodiment of an inventive Rotary folding door, which has a first wing a and a second wing b. The wing a is fixed at a point 1 on a building which is only indicated schematically 2 posted.

The wing b is attached to the wing a via bearing 6. The drawing shows with fully marked lines the wings a and b in their closed position Position, and it shows it in its open position with dash-dotted lines. The same thing applies to the rotating and folding rods used. The individual points and parts are in the closed position by a reference number and in the open position by the same Reference number marked with a trailing apostrophe, e.g. B. 6 and 6 '.

At the left end of the wing b, an arm d is attached, its shape and location can be clearly seen in particular from the illustration on the open wing b are and at the free end protruding beyond the wing b is an articulation point 7 is provided.

About a connecting rod k, which is only indicated by dash-dotted lines, is the Articulation point 7 connected to an articulation point 8 at the front end of a push member i, which hinge point in a attached to the right end of the wing a and about this protruding Rolälenbahn m is linearly displaceable. Parts d, 6, 7 and as well as the connecting rod k and the straight guide m result in an eccentric straight thrust crank, as described in detail in the main message 1 - 14 224.0. If in the Opening of the wing a, i.e. its counter-clockwise rotation, the point 8 in the straight line m moves in a straight line, is about the connecting rod k the arm d and thus the wing b pivoted clockwise, as shown a rotation of a by 900 counter-clockwise a rotation of b by 1800 clockwise causes.

The push member i is in the illustrated embodiment by one fixed pivot point 11 rotatable. It is designed in one piece with a swing arm n, a hinge point 22 is located at the free end thereof. In the illustrated embodiment rocker n and push member i are integrally formed as a triangular plate; they enclose an acute angle with one another. As you can see, the point of articulation lies 22 very far to the right when the gate is closed, which makes it possible to use the drive to be arranged very close to the goal, i.e. very little space at the side.

At the hinge point 22 a coupling g is articulated as a cranked rod is formed and the other end at a pivot point 3 at the free end of a Crank H is articulated. The crank h can be pivoted by means of a driven shaft 4, which expediently from an electric gear motor with constant angular speed is driven. As the drawing shows, the points are in the closed position 4, 3 and 22 roughly on a straight line, and in the open position are the points 3 ', 4 and 22 'also roughly on a straight line. One achieves that the speed of rotation of the wing a when opening and closing each continuously from zero rises a maximum and then falls back to zero. Also a lock through Knee lever action is possible as described in the main application P 18 14 224.0, compare part 5 there.

The parts n, g and h thus form a quadrangle with the base 4-11, and this four-bar linkage rotates the thrust member i with the desired movement characteristics.

With a corresponding arrangement of the driven thrust member i (cf. Figure 8 of P 18 14 224.0) the wing a can also be rotated by 1800 and the wing b can be folded in parallel in the open position.

By shifting the position of the individual pivot points of the system can the sequence of movements of the rotary folding gate can be influenced in a simple manner. Since that The linkage is next to the gate in the open position, it does not need to be above or below the same, but can also be placed next to the gate, which is special is advantageous if there is little space available above and below.

Furthermore, the fulcrum 11 of the thrust member i can be positionally displaceable, z. B. according to Figure 3 of P 18 14 224.0, where this pivot point is hinged to a crank which is rotated by the motor shaft 4.

2 and 3 show a second embodiment of the invention, namely a four-wing folding folding door, which swings freely above and below and in which a gear motor is provided in the middle above the door opening, which serves as a central common drive for all gate leaves. Such an arrangement according to the invention arrives laterally as shown with an absolute minimum Space, as the lever i (j) lies behind the door post when folded, and it also has a very favorable movement characteristic. - Since in Fig. 2 the left half of the goal is symmetrical to the right, only the left half is described. Likewise, only the open position of the left half of the door is shown in dash-dotted lines in FIG Lines shown to keep the drawing clear.

The outer wings of the two halves of the Xor are each on one goalpost 20 or 21 attached. The push links or folding levers are each designed in the form of a double cranked lever i or j, are each in one piece with a rocker (= connection of 11 and 22) and are the same as in Fig. 1 respectively connected to a straight thrust crank mechanism 8, 7, 6, k, d, m. To twist the Thrust members i, j via their rockers serve rods p and q, which, as shown in Fig. 3 can be seen, cranked at one end and with this end 25 or 26 at the two Ends of the crank r of a geared motor s are articulated, which is shown in FIGS 3 is shown in its position corresponding to the closed position of the gate. These Rods correspond to the coupling g according to FIG. 1. The axis of rotation of the crank r is with 27 designated. The motor s expediently has a sliding clutch t via which the drive can easily be separated from the door system for manual operation of the gate.

The inner gate leaves are on the front with switching strips 22, 23, which switch off the engine immediately when it encounters an obstacle or reverse if necessary.

The rotary folding door according to FIGS. 2 and 3 works as follows: When opening If the motor s turns the crank r counterclockwise (refer to Fig. 2) twisted. This causes the push rods (coupling) p and q, which when the Gate almost flush with each other, twisting the folding levers i and j, with i opposite clockwise and j clockwise. Twist the folding levers in turn, the respectively assigned outer gate wing and fold - over that already Straight thrust crank mechanism described - also the associated inner gate leaf at, so that when the gate is open, the position of the gate leaves and actuators results, which is shown in Fig. 2 on the left with dash-dotted lines. How one easily recognizes from the drawing, all parts are in the folded state very compact and close together, d. H. the space requirement on the side is extremely small. By choosing the right length of the lever arm of the crank r (ratio the length of r to the distance between points 22 and 22 'in Fig. 2) a very fast and achieve low-noise movement.

As can be easily seen from Fig. 2, must also here for the introduction the movement of the distance of the hinge point 22 from the gate leaf a be greater than that of the hinge point 11, both in the open as in the closed position of the Folding lever i or j. Here, too, the connection of the points 11, 22 closes a sharp one Make an angle with the junction of points 11, 8, and the distance 11-22 is essential smaller than the distance 11-8.

If the installation space is very tight, the push rod i or j also via a gear drive, - a chain drive, a hydraulic motor or a pneumatic motor, especially those with end position buffering, driven to rotate will. The illustrated embodiments are driven by a four-bar linkage but because of their favorable path-dependent speed characteristics and theirs very quiet running preferred.
