The invention relates to a device for lightening and balancing tilting doors, in particular garage tilting doors, which device has lightening and balancing means arranged on both sides of the door, both ends articulated at their ends to vertical rails arranged on the side frame and on the other hand. the articulation of the weighting members on each rail is arranged at a certain height above floor level and the articulation of the other end of the relief and balancing members is arranged close to the frame-side articulation point of each arm, and in which on a rail with a vertically guided roller, and both relief and balancing members are provided with a roller rotatably mounted at their ends at their ends.

Various relief and balancing devices are known to facilitate the opening and closing of tilting doors, especially doors which have no response outside the space to be closed. However, the main disadvantage of these known devices is that they require precise adjustment of the various relief and balancing moments that 2 60056 occur between the opening and closing limit positions during the door travel. To this end, in a known embodiment, the distance between the upper end of the elastic relief and balancing members and the upper ends of the height-adjustable vertical posts, which support the door mechanisms on both sides of the door opening, is changed, for example by means of a threaded mandrel. However, the manufacture and installation of the controls, as well as the time required for balancing, significantly increase the cost of manufacturing such a door.

It is an object of the present invention to provide a lightening and balancing device for externally responsive tilting doors which is simple, has a reasonable manufacturing cost and requires no adjustment to achieve virtually constant lightening and balancing so that the door can be used easily and comfortably throughout its size. on the way, i.e. between the opening and closing limit positions.

To achieve this object, the lightening and balancing device according to the invention is characterized in that an elliptically curved guide is arranged on the arms for each roller, and that when the door leaf is used, each roller is rotatably guided in these guides and held securely on the arms by these guides.

The invention will be explained in the following with reference to an exemplary embodiment shown in the drawing. In the drawings:

Figure 1 shows a side view of a tipping door provided with a lightening and balancing device according to the invention.

Figure 2 shows in detail the different positions of the lightening and balancing device when using a tipping door.

Figure 3 shows a larger longitudinal section of the reversible arm of the two reversible arms.

Figure 4 shows a section taken along the line IV-IV in Figure 3.

3 60056

The tilting door provided with the lightening and balancing device according to the invention shown in Fig. 1 is formed by a rigid door leaf 1 guided at the bottom by two rollers 2 in two vertical rails 3 which form columns of a fixed door frame. The two arms 4 are pivotable, on the one hand, at the upper end 3a and, on the other hand, at the side edges of the door leaf 1 at 1a in the middle of its height. At a certain height 3b of the vertical rails 3, two elastic relief and balancing members 5 are arranged, which in the example shown form relief and balancing devices with compression springs, the upper end of which supports a freely rotating roller 6 moving on a ramp 7 arranged on the arms 4. 6 and thus also the different positions taken by the lightening and balancing members 5 are shown in Fig. 2.

Fig. 3 shows a longitudinal section of an arm 4 formed by a U-profile, in which the molded steel web has a semicircular ramp 7. The cross-sections according to Figs. 4-6 show in detail the roller track 8 made in the ramp 7 for the roller 6 of the relief and balancing members.

The lightening and balancing device described above operates as follows.

When the door leaf 1 is brought into the opening position shown in full by FIG. on rails 3 and on the other hand by means of arms 4 articulated from one end at 1a to the side edges of the door leaf 1 halfway through its height, while their other end is pivotable in the upper part 3a of the vertical rails 3. The ease of use, i.e. the lightening and balancing of the door leaf, is due to both elastic relief and balancing members 5, which in the example shown are compression springs made of telescopically nested sliding tubes. The elastic force of the springs acts on the door plate 1 via the roller 6 and the ramp 7 of the arms 4, whereby it continuously equalizes the different relief moments due to the change in the distance D between the joint 4 of the arms 4 and the contact point of the rollers 6 without using control levers or the like. As can be clearly seen from the figure, the distance D continuously increases from the closed position to the open position to reach the distance. At the point of contact between the roller 6 and the ramp 7 60056, the axis of the relief and compensating weighting members 5 is always perpendicular to the tangent of the ramp 7.

As can be seen from the above, the lightening and balancing device according to the invention makes it possible to omit all control elements, and doors equipped with this device can be manufactured and used without difficulty by unskilled persons. Furthermore, due to the simple structure of the mechanical members, this device requires only relatively little maintenance.
