Description

DESCRIPTION

Connection for a movable door leaf

The invention relates to a connection for a movable door leaf, which is guided on lateral running rails by means of rollers and which is connected to a rope-shaped drive means via a connecting lever.

From DE 20 2012 012 514 U1 a spiral door leaf has been known which has a lateral drive. Thanks to a double use of guide rails, a reduction in dimensions in the area of the fence is achieved. In the implementation of a lateral drive, depending on the size of the door and its construction, a working branch is present on one side only or on both sides. In the case of a working branch on both sides, these are connected to each other with a drive shaft, so that, thanks to the use of only one drive unit, both sides can be driven simultaneously. At the lower end of the door leaf, on each side is present a clamping device with a connecting lever adjustment. In this case, the connecting lever is attached to a driver of a rope-like drive means. This document discloses in detail a generic connection for a movable door leaf. This door leaf is provided with a closure with a floor and is guided on lateral running rails by means of rollers. The door leaf has connecting levers, which are designed as substantially flat oscillating arms and which are mounted between the rope-like lateral actuating means and the door leaf. The swing arms are arranged on both sides in the lower region of the door leaf and are designed as a two-wire connection. Each oscillating arm has an upper movement point, which makes possible at least one mobility in one direction of movement of the oscillating arm towards the door leaf and is fixed by means of drivers to the variable actuating means in the vertical direction. Each oscillating arm has as a fixing a lower connection connected to the door leaf, through which at least one mobility is provided in one direction of movement of the oscillating arm towards the door leaf with several degrees of freedom and which is configured so that it is not adjustable by itself. An adjusting device is present, through which the position of the upper moving point can be adjusted vertically, continuously and steplessly. A reference position of the door leaf can be changed relative to the ground.

A sectional door is described, for example, in DE 102005023 384 B3. This sectional door has in this case a frame with guide rails and a sectional door leaf of individual sections hingedly connected to each other, which are guided by means of rollers on lateral guide rails. Document EP 2 806 095 A1 shows a further sectional door, which is guided on lateral guide rails and has lateral drive means in the form of chains.

The object of the invention is to make a connection of a movable guided door leaf on lateral running rails, so as to provide a simple adjustability during assembly for a proper closing in the area of the floor. This adjustability must be capable of being carried out easily in the assembled state of the door leaf.

The object is achieved by the features of claim 1. The following dependent claims reproduce in this case a further configuration of the idea according to the invention.

To achieve the objective, the upper point of movement of the swing arm is formed by a connecting element, which has a central area, a thread arranged inside the connecting element and a collar for fixing the connecting element, the swing arm and the dragger. The central area includes a round or domed projection, is formed as well as a mounting with various degrees of freedom for the swing arm and is connected to the driver, is arranged downstream of the shoulder on the end of the collar and is connected to the driver. The adjusting device is arranged within or on the driver to achieve an adjustability of the parallelism of the closure with the ground by means of the oscillating arms. Such a two-wire connection has the advantage that it has a statically determined position for the door leaf and itself contains sufficient mobility, which can also be referred to as a floating connection.

According to an embodiment of the invention, the lower and upper links of the oscillating arm are formed respectively by means of a link element, which has a central area, which includes a round or domed projection.

Preferably, a housing for the connecting element is created in a base body of the driver by means of an expandable arm.

The adjusting device can be arranged on the lower end of the base body.

Above all, the adjusting device can have a holding piece, which is fixed with screws to a roller carriage or the like by means of a mounting surface for the rope-shaped drive means.

In particular, the retaining piece is traversed by an adjusting element, positioning the adjusting element with its end, after passing through a nut, against a positioning surface of the driver, and the nut being immobilized against unintentional loosening by means of a safety device.

According to one embodiment, the adjusting device has a retaining part, which is connected to the rope-shaped drive means with screws and via a mounting surface. A recess is provided within the retaining piece which is configured so that the head of a nut is secured against rotation by means of the recess. The retaining piece is traversed, in this case, by an adjusting element, the adjusting element attacking with its end, after passing through the nut, against a positioning surface of the driver, so that, by means of rotational movements of the adjusting element, the position of the driver can be changed and therefore also the attached swing arm can be changed simultaneously.

The door leaf can be provided in the configuration of a sectional door or a spiral door or a high-speed door or a tilting door and can be provided with a connection as described above.

Other advantages, characteristics and possibilities of application of the present invention result from the following description in connection with the examples of embodiments represented in the drawings.

In FIG. 1, the lower part of a door leaf 1 is reproduced in a principle sketch. The door leaf 1 is suspended on each side by means of oscillating arms 9. Such an oscillating arm 9 has a point upper link 3 and lower link 4 which are designated in their entirety link 6. Link 4 may be a pure pivot point or a fixture with various degrees of freedom. In the embodiment as a pivot point, mobility of the swing arm 9 towards the door leaf 1 is provided only in one direction of movement. The point of movement 3 is designed in such a way that it is always configured in several directions of movement. The bifilar connection 6 can be seen as part of a substantially cardanic suspension in one plane. In this case, a lower closure 26 of the door leaf 1 always retains its parallelism with a floor 5 after adjustment.

The point of movement 3 is fixed by means of drivers 13 to a rope-shaped drive means, not shown, which can be changed in the vertical direction within running rails 2 or on separate rails. This is made explicit in particular by the illustration according to FIG. 2. In this case, the running rails 2 are shown in conjunction with drive rails 18, the connection 6 being arranged on each side between the vertical edges of the sheet metal. door 1 and the drive rails 18. The position of the drivers 13 on each side of the door leaf 1 is changed through rope-shaped drive means, the drive means being driven by means of a common drive.

The location of the bifilar connection 6 on both sides in the lower end region of the door leaf 1 can be deduced from FIG. 3 in a perspective view. On the door leaf 1, a sealing gasket 7 is present in the lower closure 26 to seal against the ground 5. In the area of the closure 26, the connections 6 are arranged on each side. The connection 6 can also still simultaneously have a retainer for a lower roller 14 that ensures proper guiding of the door leaf 1 on the running rails 2. The roller 14 is in this case mounted on a shaft 10 within a roller bearing 11.

Looking at FIG. 4 it is obvious that the connection 6 with the swing arm 9 is arranged between the vertical edge of the door leaf 1 or a panel 8 and the running rail 2. The swing arm 9 is in this case connected in its upper free end with the point of movement 3 which is movably mounted within or on the driver 13. In order to properly join the connection 6 to the panel 8, a base 12 is present, by means of which the connection to the panel 8 is secured by means of bolted connections not shown.

Thanks to the individual representation of the connection 6 according to FIG. 5, it is obvious that, downstream of the base 12, a laterally bent side part 16 is present. In a preferred embodiment, the connection 4 is contained within the lateral part 16 as a rotary connection with a screw connection, which can also be deduced in particular from FIG. 6. The point of movement 3 at the upper end of the swing arm 9 is it is formed by means of a connecting element 19, which allows a mobility of the oscillating arm 9 in various degrees of freedom or in at least two planes.

From FIG. 5, it can also be deduced the roller bearing 11 which is traversed by the roller shaft 10 and is variable in the axial direction within the roller bearing 11 and whose path can thus be adapted on the rolling rail 2. The roller bearing 11 is fixed to the base 12 by means of fixings 20.

This arrangement can also be deduced from the illustration according to FIG. 7. The insertion of the connecting element 19 on the upper end of the oscillating arm 9. The connecting element 19 according to FIG. 8 is immobilized on the end on the arm. oscillating 9 with respect to a projecting collar 25, a thread 24 being present inside the connecting element 19. To carry out immobilization by means of a collar 21 on the oscillating arm 9, surfaces 23 are present for the use of a tool. The central area of the connecting element 19 is characterized by a round or domed projection 22. Following this, on the end there is a collar 21 which, after being inserted into the driver 13, causes the driver 13 to be made unfeasible by means of an immobilizer 15. Therefore, thanks to the configuration of the projection 22, the oscillating arm 9 can move in various directions and, consequently, can make the entire door leaf 1 adjustable. To achieve a more precise adjustability of the parallelism of the latch 26 with the floor 5, an adjusting device 17 is arranged within or on the driver 13.

Thus, during an actuation of the adjusting device 17, a relative reference position of the movement point 3 with respect to the ground 5 can be changed.

The position of the oscillating arm 9 between the right side realization of the driver 13 and the limitation of the left side through the base 12 can be deduced very clearly from figure 9. In this case, on the driver 13, the point of movement 3 it has been made with the connecting element 19, the outer closure forming a screw connection 27. In the same way, at the lower end of the oscillating arm 9, the connection element 19 has also been made at the connection 4. It is shown here that the collar 21 engages against the outer surface on the left side of the oscillating arm 9. The immobilization of the connecting element 19 with respect to the lateral part 16 is also achieved here by means of a screw connection 27. Thanks to the oblique position of the oscillating arm 9, it is obvious that opposite the left side with the driver 13 and on the side Right the base 12, with the door leaf 1 not shown here, is configured as a floating suspension by means of the two-wire connection 6. Thanks to the adjustment device 17, the lock 26 can be adjusted exactly with the aid of the floating assembly.

In a detailed representation according to FIG. 10, the driver 13. The driver 13 is represented in this case substantially of a base body 37 which has elongated holes 30 in the upper part for fixing purposes. By means of an expandable arm 40 on the base body 37 a housing 29 is created for the connecting element 19. This housing 29 is open, so that the movement point 3 can be inserted there in an embodiment with the connecting element 19. In this case, the collar 21 is applied here to a surface of the base body 37. In order for the oscillating arm 9 inserted into the housing 29 through the connecting element 19 to maintain its position, a safety device 28 is present This safety device 28 can be realized by means of a screw element.

At the lower end of the base body 37, the adjusting device 17 is shown. The adjusting device 17 has a retaining piece 35 which can be fixed with screws 36 by means of a mounting surface 41 to a roller carriage, not shown. or the like for the rope-shaped drive means. Inside the retainer 35 is a recess 34 that is configured so that the head of a nut 32 is secured against rotation. The retaining piece 35 is traversed in this case by an adjusting element 31, positioning the adjusting element 31 with its end, after passing through the nut 32, against a surface position 33 of the driver 13. Thanks to the rotary movements of the adjusting element 31, the driver 13 can thus be changed in its position and therefore also simultaneously the attached oscillating arm 9. Following a change in position, the driver 13 is immobilized by means of bolts 39 through the elongated holes 30. By means of a safety device 42 the nut 32 is also immobilized against unintentional loosening. The safety device 42 can, for example, also comprise a lock nut.

The location of the connection element 19 at the upper end of the oscillating arm 9 within the driver 13 can be deduced from the perspective representation in FIG. 11. By means of the safety device 28 a removal of the connection element 19 that is secured can be ruled out by means of the screwing 27 with respect to the oscillating arm 9. As can be deduced in addition to the illustration, the point of movement 3 is a movable joint in various degrees of freedom, through which the closure 26 can experience a precise balance with respect to to the ground 5 in cooperation with the joint 4. This is achieved because through the embodiments on both sides of the connection 6 a floating, per se, but statically stable positioning of the door leaf 1 is achieved.

Thanks to FIG. 12, a cooperation of the driver 13 and the adjusting device 17 can be illustrated once again in a view from behind. Here again it is evident that the adjusting element 31 presses against the positioning surface 33 of the driver 13 and thus, in the case of a position variation of the adjusting element 31, a lower end 43 of the base 12 can be changed in its relative position. After the adjustment carried out, an immobilization of the driver 13 is achieved through the bolts 39 that engage in the elongated holes 30.

The door leaf 1 can be a component of a sectional door or a spiral door or a high-speed door or a tilting door.
