In sectional doors guided in two guide rails by means of rollers, it is known to mount the torsion spring shaft at the rear end of the horizontal guide rail region and guide the cable from the cable drum located on the torsion spring shaft through the guide pulley arranged in the arched guide rail region to the lower end gate section and fix it there. The adjustment of the length of the tow rope as well as the adjustment of the bias of the torsion spring is carried out in the prescribed manner.

SUMMARY OF THE INVENTION

In view of what doors are currently available, the present invention aims to simplify the installation of the door on site and, in particular, to simplify the adjustment of the weight balancing device. Another object of the invention is the possibility of adapting the torsion spring arrangement to local conditions.

Motorized or manually operated folding or sectional doors

- with at least one closing element for closing the clear gate in the closing position of at least one closing element,

- with one guide rail, preferably single-lane, consisting of a vertical section, an arch section and a horizontal section,

- with guide means, such as guide rollers, mounted on at least one closing element and guided in a guide rail, and

- with a mass balancing device arranged on a horizontal section and consisting of a torsion spring arrangement and a traction means, in which the traction cable is engaged at one end on at least one closure element and at the other end on the rope drum and the rope drum is propulsively coupled to the torsion spring arrangement .

The essence of this invention lies in it that torsionally spring arrangement together with rope drum j sou led horizontally sliding on both horizontal sections guide rails, whereas weight balancers the device is provided guide foot.

By the horizontal displacement of the longitudinal building unit consisting of a torsion spring arrangement and a cable drum and guiding on both horizontal sections of the guide rail, the adjustability of the mass balancing device is greatly simplified by moving the mass balancing device at each of its ends as well as rail until the correct adjustment is achieved with the weight balancer. In this position, the end of the weight balancing device is fastened in a suitable manner on the respective horizontal section of the guide rail. In this way, the spacing of the guide rail in the region of the mass balancing device also maintains a precisely determined value.

In order to achieve accurate guidance, preferably without torsion, between the weight balancer and the horizontal sections of the guide rail, the weight balancer is provided with a guide foot.

Clamping screws and / or elongated holes on the two-sided ends of the weight balancer or on the guide feet facilitate accurate adjustment and fastening of the ends of the weight balancer on the horizontal sections of the guide rails. The torsion spring shaft may be arranged immediately at the height of the horizontal section of the guide rail, in particular at the center of the guide rail (taken vertically).

However, due to the particular spatial conditions, it is also possible to arrange the weight balancing device by means of a bracket or similar measures somewhat higher or slightly lower than the horizontal section of the guide rail.

Further features, in particular the use of the door according to the invention, for situations with a considerably low ceiling height are given in the examples.

All of the structural elements mentioned herein which are required according to the invention are not subject to any particular conditions in terms of their dimensions, design, material selection and technical concept, so that the selection criteria known in the field of application can find unlimited application here.

DETAILED DESCRIPTION OF THE INVENTION

In the embodiment according to FIGS. 1 to 7, a sectional door consisting of the door sections 5A to 5D as the closing element 5 is opened and closed by the known electric drive 10; this consists of a motor and control unit 10A and a drive rail 10B comprising a linear drive means which are mounted on the garage ceiling 2 approximately midway between the two guide rails 7 arranged at the sides of the closure member 5. The rod 10c transmits the driving force from the driving rail 10B to the center of the upper edge of the uppermost gate section 5A.

The two guide rails 7 are in the illustrated, preferred embodiment shown in a single-stream design and consist of a vertical section 7A, a horizontal section 7B and an arched section 7C; guide rollers 6A to 6E, which are mounted on the upper or lower edges of the door sections 5A to 5D. In this case, the uppermost guide pulley 6A is mounted at the free end of the lever 8y, the other end of which is rotatably mounted below the upper edge of the door on the uppermost door section 5A to rotate the uppermost door section from the closed position shown in FIG. .

In the region of the rear end of the horizontal section 7B of the guide rail 7, a weight balancing device 50 is provided, which will be described in more detail below. From the weight balancing device 50, the pulling cable 51A of the pulling means 51 extends approximately parallel to the horizontal section 7B of the guide rail 7 to the two guide rollers 51C arranged in the region of the arched section 7C and from there further to the lower edge of the door where 6E on the closure element 5 (see also FIGS. 5 and 6).

The other end of the tow rope 51A can be wound and unwound from the rope drum 51B. The cable drum 51B is part of a traction means 51 which is rotatably driven thereto by a coaxially arranged torsion spring 52A of the torsion spring arrangement 52, which is another part of the weight balancing device 50.

The cable drum 51 and the torsion spring arrangement 52, including but not limited to a retaining beam 52B extending over the entire length of the weight balancing device 50, and the bracket 52C, form a weight balancing device 50. The bracket 52C is screwed to a guide foot 53 which is The guide rail 7 is slidably guided within the profile of the guide rail ^and, once it has reached the desired position, can be fixedly screwed to the guide rail by means of screws 53B.

Sliding by fine adjustment is provided by the longitudinal holes 53A of the guide shoe 53. The stop bracket 54 with the adjusting screw 55 allows fine adjustment by the front stop 53C of the guide shoe 53. In addition to this fine adjustment, a coarse adjustment of the weight balancer 50 is also possible. holes are provided at certain intervals of the horizontal section 7B of the guide rail 7 to accommodate the screws 53B for the guide foot or bracket 54. For the sake of clarity, these additional holes are not shown in the drawing.

By guiding the weight balancing device in the guide rail to the desired position, the assembly of the door is greatly simplified and the adjustment of the weight balancing device and the spacing of the guide rails is kept to the desired extent.

These doors function in the usual way: When the door is opened, the pull rope 51A supports a torsion-driven drive

26 through the spring 52A through the cable drum 51B to lift the door. The torsion spring 52A is slowly released. When re-closing the door, when the weight of the door under gravity supports the closing movement, the pull rope 51A is slowly unwound from the rope drum 51B. Now the cable drum 51B again tensions the torsion spring 52A by the same amount by which the torsion spring has been released during opening.

In an alternative embodiment, the following differences occur from the first exemplary embodiment: The guide shoe of the weight balancer comprises a horizontal section of the guide rail of a length sufficient for guide and fixation purposes and carries all the components necessary for fine adjustment. The locking screws allow the guide shoe to be firmly clamped on the bent lower edge of the guide rail profile. The guide shoe has a holding region extending above the guide rail for the weight balancing device, so that it is arranged above the horizontal guide rail.

A single guide pulley, which is arranged on the radial outer side of the arc section, now serves for returning the tow rope. In this exemplary embodiment, the weight balancer is relatively close to the arc section and utilizes the free space available above the horizontal section below the garage ceiling if the door opening ends considerably lower than the garage ceiling.
