"Tilting door" - ·

The present invention relates essentially to a tilting door for closing, or opening or releasing an opening any building such as a parking garage or a Car garage.

There are already different types of tilting doors known with a plate or the like, which over with the back of the plate fixed side arms, each of which carries a counterweight at the ends, can be pivoted about a horizontal axis is.

However, those proposed so far have been counterbalanced Tilting arrangements quite complicated and it was not always possible to slide the door parallel during their Rotary movement in your door opening takes up the smallest possible space to rent. In addition, in the case of doors with freely suspended counterweights, the pendulum or swinging movement of the counterweights was undermined the effect of opening or closing the door from a reaction on the plate forming the door, so that this too

was set in vibration and how understandable the operating mode the door affected whether it was operated by hand or by some drive device

The aim of the present innovation is essentially the opening or closing a tilting door to solve the problem posed by its unwanted swinging movement and for this purpose she suggests a tilting door with a special device, which with the parallel rotational movement of the door and the counterweights, they are always motionless in the vertical position holds.

The object of the innovation is expediently a tilting door of the type that has a plate or the like, which by means of side arms which are firmly connected to the upper rear side of the plate and carry at least one counterweight at their ends is pivotable around a horizontal axis, characterized in that a deformable one which forms a parallel guide Articulated parallelogram is provided between each arm and its associated counterweight in such a way that each counterweight at the parallel rotational displacement movement of the plate and the counterweights remains guided in a positive manner.

It goes without saying that the affected joint parallelogram, which forms a parallel guide, is a very simple device, to prevent the counterweights and, accordingly, the door from swinging while they are being tilted, so that on the whole a door designed according to the basic idea of the innovation not only offers excellent operational safety or, Has reliability, but is also very simple and inexpensive to manufacture in terms of its construction.

According to another characteristic feature of the innovation, the joint parallelogram forming a parallel guide consists of one first short vertical and spatially fixed side, while the counterweight is connected to and attached to the second short side Is articulated parallelogram.

According to a preferred embodiment, there is the first short side

from a plate attached vertically to the side of the door opening or the like, which at their upper end has a horizontal bolt or tenon around which the arm can be pivoted, and on at its lower end another horizontal bolt or tenon, on which the end of a first long side of the parallelogram is hinged, has.

According to another characteristic feature of the innovation, the second short side, to which the counterweight is attached, consists of a rod or a handlebar or the like or with its Ends on the one hand at the end of the arm and on the other hand at the other end of the first also by a rod or a handlebar or The like. Formed first long side is hinged.

According to yet another characteristic feature of the innovation, each arm consists of a first arm running perpendicular to the plate Part, the end of which is pivotable on the horizontal pivot pin and extended by a second arm part, which forms an obtuse angle with the first and forms the second long side of the parallelogram, at the free end of which the the counterweight-bearing rod or the like is articulated.

According to another embodiment, each arm is designed in duplicate and consists of an upper arm and a lower arm which are perpendicular to the plate, the first being short perpendicular and the stationary side of the parallelogram is assigned to the lower arm and the second short joint side carrying the counterweight is assigned to the Upper arm is assigned, and wherein a handlebar, a rod or the like. The ends of the upper and lower arm connects to the to form the second long side of the joint parallelogram

The characterizing features and advantages as well as others of the innovation emerge more clearly from the following detailed description with reference to the attached drawings, which are only given by way of example. Show it :

According to an exemplary embodiment and with reference to FIGS. 1 to 4, a tilting door according to the invention consists essentially of a plate or board 1, which is connected to the upper rear side 1a of the plate 1 by the side arms 3 around the horizontal pin or Bolzen2 is pivotable »with the arms at their ends an over a deformable one forming a parallel guide device 5 Carrying articulated parallelogram counterweight 4 articulated on arm 3.

This joint parallelogram 5 comprises a first short side 6, a second short side 7, a first long side 8 and a second long side 9, which will be described in detail below.

The first short side 6 is perpendicular and spatially fixed. As can be seen better from FIG. 4, it preferably consists from a plate or the like. 6a, which is perpendicularly attached to the side 10 of the door opening, the door between a threshold 11 and a door lintel 12 which can be seen in FIGS. 1 to 5 can be pivoted about the horizontal pin 2. The plate 6a contributes its upper end a horizontal pin or bolt 2a, about which the arm 3 is pivotable ver, and at its lower end one further horizontal pin or bolt 13 on which the end of the first long side 8 of the parallelogram 5 is articulated. Of course, without leaving the scope of the innovation, one could omit the plate 6a and simply attach the horizontal pins 2a and 13 directly to the wall 10 of the door opening.

The second short side 7 of the articulated parallelogram 5, to which the counterweight 4 is somehow attached, consists of one suitable link, such as a rod, a handlebar or the like with its end 14 at the end of the Arm 3 and with its or its end 15 at the other (the end 13 opposite) end of the first long side 8 is hinged.

This first long side 8 consists of any desired |
