Spring device for operating swing doors

The present invention relates to spring-operated swing door, or more particularly to a spring device for operating of swing doors. Various types of swing doors are known which, depending on the design, are equipped with a spring device in order to reduce the effort when opening the door as much as possible and to compensate for the weight of the door when it is operated

It is also known that the devices mentioned consist of a set of springs, mostly spiral springs, which act on the swing doors on both sides. Have these feathers the task of the bumps they face when opening and Closing the door are exposed to counteract in order to achieve an almost complete weight compensation during the Opening and closing.

It is also known that for the devices mentioned It is very important that the springs act on the loads at exactly the same time in order to ensure perfect operation of the door, without lateral 'Jru'7i * chterscheir "" ng "n. to reach. Step on different types of spring-operated swing doors Imbalance phenomena and disrupt their operation.

Attempts have already been made several times to eliminate the disadvantages mentioned above. The practical execution of this However, devices were too complicated and to this day there is no technically good, economical and reliable one Solution to the problem found.

In the embodiment according to the invention, the above-mentioned disadvantages completely eliminated.

The present invention relates to a spring device for operating swing doors, consisting of two Spiral springs that act on the door with the help of two ropes, with one end of the ropes attached to the sliding pegs the door are fastened and the other end is wound onto a drum which is drawn onto a housing in which the springs are wound, characterized in that that the housings, in which the spiral springs are wound, are connected to one another by two gears the same number of teeth built into the housing. and have the task of having the same effect and counteraction. ^ - · to transfer load to the springs

Further features of the device according to the invention are now on the basis of the accompanying drawing, on which the subject of the invention attached to a swing door schematically and is shown in a special perspective, described more clearly «,

With (1) the frame of the swing door (2) is referred to, which mainly consists of two beams (3) and (4), the bottom are attached (is not shown on the drawing) and are connected at the top with a crossbar (5).

The carriers (3) and (&) are shaped so that on each of them has a sliding guide (7) in which a pin (8) and a pin (9) are guided, which are laterally attached are attached to the flanks of the swing door (2).

With (10) and (11) two brackets are designated, each with one end in (12) and (13) on the swing door (2) and with the the other end to a pin (16) and a pin (17) which are attached to the carrier (4) and (3), respectively, are articulated.

With (18) and (19) two spiral springs are designated, which with one end in (20) and (21) on the spring housing (14) and (15) are attached and in the opposite direction on a remaining Zspfcii held by the transverse bar (22) or (23) are wound.

On the above spring housings (14) and (15) a receiving drum (24) or (25) is attached, as well as a gear (26) and a gear (27) with the same number of teeth that mesh with one another.

On the above recording drums (24) and (25) are two Steel cables (28> and (29Ϊ wound, each with one end on one of the pegs (8) or Ϊ9) are attached.

The above ropes (28) and (29) move freely on two pulleys (30) and (31) located near the top of the girders (4) and (3) are arranged.

The modes of operation of the subject matter of the invention are clear can be seen in the above declarations.

If one of the two springs (18) and (19) should be loaded more than the other spring, it becomes part of it Ube ^ load with the help of the gears (26) and (27) automatically transferred to the other spring, so that the two «ropes (28)« nd (29) always have the same load and the side effect on the swing door (2) is always balanced.

The mode of operation of the rest of the mechanical device of the swing door is not explained here, as it already does is well known.

The above description is a preferred embodiment; in the "practical application various changes can be made without exceeding the scope of the invention.
