FIG. 1 shows a lateral cross-section of a device according to the invention Door damper 10 in a first embodiment. The door striker 10 has a box part 11 which in a main section facing away from the shaft Side vertically extends and this vertical Section 11a with an upper part 15a and a lower one Part 15b forms. In cross section, the door striker 10 in the area where the upper part 15a and the lower part 15b abutting one another, a first tread carrier 12, located on the shaft side of the box part 11, in the Figure 1 on the right side of the box part 11, from the box part 11 away in the direction of the shaft, so in the figure after extends to the right. At a free end 12a on the shaft side of the first tread carrier 12 is at least one Tread, hereinafter referred to as first tread 13, educated. Further, at the free end 12 a of the first Tread carrier 12 a second tread 14 is formed, that of the first tread 13 is vertically opposite is. In this case, the first tread 13 is directed upward and the second tread 14 points down. Both treads are each shaped as 180 ° bows and on the Shaft side connected to each other. The first tread 13 and the second tread 14 each form rails for corresponding rollers of a door leaf, on the Rolling run rails can.

The first tread carrier 12 extends in the longitudinal direction of the door fighter 10. Since accordingly the two mentioned Running surfaces 13 and 14 also in the longitudinal direction of the door fighter run, is thus a guide device over provided the width of the door fighter.

According to Figure 3, the vertical portion 11a of the box part 11 with the upper part 15a and the lower part 15b facing the door user and covers the upper area of a Wall opening 46, in which the door striker 10 is arranged is. As a result, the treads, or the contact points between the respective rollers and the running surfaces, from shielded from the user, so that a injury Intervention in the door leaf guide is effectively prevented.

Said wall opening 46 is e.g. in a manhole or Car wall 45 arranged in the figure 3 above fragmentary is shown. The door striker 10 points at the free End of its horizontal cover 11b also a fold 16 on, for example, a cover 40 as Cover can be hung against the open shaft.

From Figure 1 it can be seen that the entire door striker 10 is made of a single bent sheet metal. in the Result, the treads are integral with the box part and formed the tread carrier, which has advantages in the Manufacturing offers. The shape shown here in cross section the door fighter 10 can be by profiling means achieve a profiling or the like. The door fighter 10 can in particular by rolling as a piece goods getting produced.

When making the door fighter by rolling become out the sheet metal following components of the door fighter in succession educated. First, an upper horizontal cover 11b of the box part 11 formed, and then the upper part 15a of the substantially vertical section 11a. Thereafter, the sheet is bent by about 90 °, to form the first tread carrier 12, from the upper first tread carrier region 12b and from the lower first tread carrier portion 12c is made. The deformation of the sheet happens in such a way that on free end 12a of the tread carrier, ie between the upper and lower first tread carrier areas, the first tread 13 and the second tread 14 are provided are, with the sheet directly from the first to the second Running surface runs. This is followed by the sheet metal after the lower first tread carrier area again Deformed 90 °, so that the lower part 15b of the substantially vertical portion 11a is formed, wherein the lower part 15b is aligned with the upper part 15a. The lower Part 15b is finally bent 90 ° back to one second tread carrier 22 form, at the end a third tread 23 is formed. An explanation of individual characteristics of the product manufactured in this form Door fighter is described below with reference to FIG 3 given.

Alternatively, the door protector by edges of sheet metal plates be made with an edging machine. As a result of Deformation of a single sheet is the first tread carrier 12 of two superimposed sheet metal sections 12b and 12c. By thus compared to the cross section of the box part doubled wall thickness is for the first tread carrier 12 ensures increased stability, what with regard to a possible increase in distance between the vertical portion 11a and the tread 13 is advantageous. The stability of the first tread carrier 12 can be further increased by at the the shaft facing away from the outside of the substantially vertical Section 11a between the part 15a and the part 15b in the area indicated by I in FIG Longitudinal weld is pulled, passing or with interruptions over the entire width of the door fighter extends in its longitudinal direction. Alternatively, or but also in addition to the aforementioned longitudinal weld in area I, the two superimposed tread carrier areas in the horizontal area between the substantially vertical portion 11a and the free one End of the first tread carrier 12 with each other e.g. Point or hole welding connected and / or screwed be.

Figure 2 shows the door striker 10 of Figure 1 in a perspective view. As can be seen from Figure 2, extend the first tread 13 and the second tread 14, at the free end 12a of the first tread carrier 12th on the inside of the box part facing the shaft 11 are formed over the entire width of the door fighter 10 in the longitudinal direction. One door leaf or several Door leaves can thus be over the entire width of the Move door fighter 10 horizontally.

The door striker 10 has in its upper portion 11b further Through holes 17 on, for a corresponding attachment of door fighter 10 at a door surround or Manhole or car wall 45 are provided.

FIG. 3 shows the door hinge 10 in FIG a side cross-sectional view with a door leaf 18, that at the free end 12a of the first tread carrier 12th is mounted. In detail, the door leaf 18 has a upper door leaf suspension 19, on the one roller 20 is arranged. Vertically aligned with the roller 20 is on the door leaf 18 also a counter-roller 21 is arranged. The distance between the respective axes of the roller 20 and the counter-roller 21 is dimensioned so that he with the distance of the first tread 13 from the second Tread 14 is tuned. The cross-sectional representation FIG. 3 clearly shows that both rollers 20, 21 are concave over their width to one another Convex curvature of the respective tread 13, 14 adapt. By this vote of the rollers on their associated Tread can be in the result a punctual unrolling the rollers and thus an exact Längsverschieblichkeit achieve the door leaf. The roller 20 and the Counter roll 21 comprise the free end 12a from above and from below, causing unwanted vertical movement of the door leaf 18 and thus excluded a "derailment" of the door leaf is.

In the figure 3 above, a part of a wall 45 is shown, here forms the upper edge of a wall opening 46, in which the door striker 10 as the upper end of the door opening 47 is arranged. Below this wall portion 45 is the upper horizontal cover 11b of the box part 11 is arranged. Here, the box part 11, for example, directly abut the wall 45, or a gap between the box part 11 and the wall 45 (as shown in FIG. 3) can suitably filled by a corresponding sealing material be. The wall portion 45, on which the box part with its upper cover rests, as masonry or but also be made of metal and / or plastic. Further, in Figure 3 below, with reference numeral 47 is a door opening indicated below the lower end of the lower Part 15b starts and the usable door opening for the Door user forms.

The illustrated in Figures 1 to 3 embodiment of the Door fighter 10 is designed so that door leaves in one Level can be moved. Thus, this is suitable Embodiment preferably for a einblättrige, laterally opening sliding door or a zweiblättrige, in the middle opening sliding door. In contrast, in Figure 4 is another Embodiment of the invention door closer 10th shown in a side cross-sectional view, at the various door leaves in adjacent levels are guided, so that this further embodiment preferably for a zweiblättrige, laterally opening Sliding door or for a four-leaf, central opening Sliding door is suitable. This further embodiment is correct essentially with the embodiment shown in Figures 1 to 3 the door fighter 10 match, being identical Elements each denoted by the same reference numerals are. To avoid repetitions are below only the relevant differences explained.

At the lower end of the lower portion 15 of the box part 11th (see Fig. 4) extends in the direction of the shaft a second Tread carrier 22, in the same way as the first Tread carrier 12 and parallel to it in the longitudinal direction the door fighter 10 extends, and at its free end 22a a third tread 23 is formed. The third tread is also in the form of an upward facing 180 ° arc formed. The third tread 23 serves as Running track for another door leaf, offset laterally is guided to the above-mentioned door leaf 18, which on the first tread 13 and the second tread 14 is guided.

Figure 4 illustrates that the distance between the vertical Part 11a and the rails 13 and 14 in this Embodiment is made larger than the distance between the vertical part 11a and the tread 23. Further has the lower first tread carrier portion 12c of the Tread carrier 12 at its bottom a fourth Tread 24, the third tread 23 opposite and is aligned with this vertically. In terms of on a trouble-free production, eg. By means of a Profiling machine, the fourth tread 24 is the same Way in shape like the above mentioned other treads a 180 ° arc formed. Here are the first and second tread 13, 14 opposite the third and fourth Tread 23, 24 offset laterally, so that accordingly two laterally offset guide planes are defined.

In Figure 5, the door striker 10 of Figure 4 is in a perspective view shown. It can be clearly seen here that the free end 22a of the second tread carrier 22 parallel to the free end 12a of the first Tread carrier 12 and laterally offset to this over the entire width of the door striker 10 in its longitudinal direction extends. As a result, a mobility of allows two side by side door leaves, without that they interfere with each other in contact.

FIG. 6 shows a lateral cross-sectional view of the lower part of FIG Referring to Figures 4 and 5 explained door striker 10 with two different door leaves, which correspond to the explained lateral offset of the two treads 13, 14 relative to the two treads 23, 24 in side by side lying levels are performed. Here is next to the Door leaf 18 hinged to the door panel another door leaf 25. One attached to the associated door leaf suspension 41 Roller 26 is on the third tread 23rd placed.

On the door leaf suspension 41 is above the roller 26, and with this vertically aligned, a sliding element 27th attached, which at its fourth tread 24 facing Side has a groove 28. The groove 28 is so dimensioned so that the sliding member 27 includes the fourth tread and thereby a guide of the corresponding door leaf 25 ensures. The distance between the roller 26 and the sliding element 28 is at the distance between the third Tread 23 and the fourth tread 24 matched, so that a vertical lifting of the roller 26 of the third tread and thus a derailment of the door leaf 25 is excluded. However, instead of the sliding member 27 can Alternatively, another roller provided be, which rolls on the fourth tread 24 and thus ensures a secure guidance of the door leaf 25.

In contrast to the explained with reference to Figures 1 to 3 Embodiment is on the door leaf 18, which at the first and second tread 13, 14 is guided instead the counter-roller 21 a sliding member 29 is mounted, whose upper side, i. facing the second tread 14 Side, having a concave curvature, that of the convex Curvature of the second tread 14 is adapted.

From Figure 6 it is further apparent that the sliding member 27th and the sliding element 29 can be of identical design, which advantageously leads to cost savings. One Such sliding element 27, 29 thus has on its one side the surface 24 adapted groove 28 and at the other Side adapted to the surface 14 groove, and only needs with the proper right alignment on the Door leaf 18 and be mounted on the door leaf 25 to the to form desired counter-guide for this door leaf.

As can be seen from FIG. 6, the lower one shields Part 15b of the box part 11 of the door fighter 10 and the bottom the guide part 22 and the third tread 23rd and the fourth tread 24 and the guide of the door leaf 25 suitably from the user, so that a injury Intervention in this leadership effectively excluded is. Since the door striker 10 as explained above made entirely from a single bent sheet metal is, and thus the said lower part 15b and the Guide member 22 is part of the box part 11 is no additional construction required to the mentioned To ensure shielding.

Similar to the representation in FIG. 3, in FIG. 6 on the left above, a portion of a wall 45 is shown as an upper portion a wall opening 46, against which the upper part 15a of the im essential vertical portion 11a is applied. in this connection A steel girder forms the wall close above the wall opening 46. For this purpose, a door opening 47 is indicated below, the begins below the second tread carrier 22. In difference to the embodiment shown in FIG the sheet is shortened following the third tread 23 running, resulting in an even easier profiling of the Sheet metal guaranteed in this area.

Figure 7 shows the door warper according to the invention in one another embodiment in which three juxtaposed Door leaf guides are provided. Hereby points Each door leaf guide has a main and a counter guide surface on. In detail, here the Türkämpfer except the first tread carrier 12 and the second tread carrier 22 also has a third tread carrier 62, at the same at a free end thereof two Treads are formed. With further folds or the arrangement of folds at other locations of the Türkämpferquerschnitts can be more guide surfaces, or also differently arranged guide surfaces, create. through the further folding of sheet metal areas in the longitudinal direction the door fighter with appropriate formations can at any desired point in the cross section of the door fighter further treads are formed.
