(3) FIG. 2 shows a schematic side view of a parking apparatus having a door apparatus;

(5) FIG. 4 shows a schematic illustration with two adjacent side views of a door apparatus in the closed position and in the open position.

DETAILED DESCRIPTION

(6) FIG. 1 shows an oblique perspective view of a parking apparatus 70 having two adjacent door apparatuses 1. The parking apparatus 70 is used for parking vehicles and has two platforms 73 which are arranged beside each other and which can be positioned by means of a movement device 71 in each case relative to an access opening A and which each have a parking surface 74. One of the two door apparatuses 1 is arranged in the access openings A in each case.

(7) Below, only one of the two door apparatuses 1 is described since they may in any case be configured in a structurally identical manner. As can be seen in FIG. 1 in conjunction with the schematic illustrations of FIGS. 2, 3 and 4, the door apparatus has two vertically orientated guide rails 2, 3 which laterally delimit the access opening A. An outer door element 20 is displaceably supported in or on a vertically orientated outer guide 4 of the guide rails 2, 3. An inner door element 30 is displaceably supported in or on an inner guide 5 which extends in a parallel manner adjacent to the outer guide 4. The inner guide 5 is also formed by the guide rails 2, 3.

(8) In the shown closed position SG of the door apparatus 1, the inner door element 30 is in each case arranged in a first region B1 of the access opening A which is located lower than a second region B2, in which the outer door element 20 is arranged. The outer door element 20 and the inner door element 30 are arranged in an open position (cf. reference numerals SO in FIG. 4) of the door apparatus 1 in a third region B3 of the access opening A which is located in each case higher than the first and second regions B1, B2. As can be seen in FIGS. 2 and 4, the first and second regions B1, B2 intersect and the second and third regions B2, B3 intersect.

(9) With the locking element 40 of a locking apparatus 39 as illustrated in FIG. 3, a blocking state S can be brought about in which the locking element 40 blocks the displaceable bearing of the inner door element 30 relative to the two guide rails 2, 3 in the closed position SG.

(10) Furthermore, the door apparatus 1 has a coupling element 50 which is schematically illustrated in FIGS. 2 and 4 and which can be arranged on one of the inner and outer door elements 20, 30 and, in this instance, is arranged at the upper end of the inner door element 30. The coupling element 50 cooperates with the outer door element 30 in such a manner that the locking element 40 blocks the displaceable bearing of the outer door element 20 in the blocking state S relative to the two guide rails 2, 3 indirectly via the inner door element 30. The coupling element 50 is thus in the form of a holding-down member. Stops on the guide rails 2, 3 with which the outer door element 20 is blocked with respect to movement into the first region B1 are not illustrated.

(11) As can further be seen in FIGS. 2 and 4, the coupling element 50 cooperates with the outer door element 20 in such a manner that between the outer door element 20 and the inner door element 30 no gap can be pushed open. Instead, the coupling element 50 cooperates with the other of the inner and outer door elements 20, 30 in such a manner that the inner door element 30 can be pushed by at least 50% beside (or behind when viewed from the front) the outer door element 20. Furthermore, the coupling element 50 cooperates with the outer door element 20 in such a manner that the inner door element 30 during displacement into the third region B3 also pushes the outer door element 20 from the second region B2 into the third region B3. The coupling element 50 is thus in the form of a carrier. To this end, the coupling element 50 is constructed as a rigid non-movable element which is constructed or arranged on the inner door element 30. From here, the coupling element 50 protrudes in such a manner from the rear between an upper and a lower frame profile 21, 22 of the outer door element 20 that it is arranged in the closed position SG at the upper side adjacent to the lower frame profile 21 and in the open position SO is arranged at the lower side adjacent to the upper frame profile 22. Between the upper and lower frame profiles, the coupling element 50 can be simply pushed past the outer door element 20. Optionally, the coupling element 50 may have a plurality of individual elements which are arranged in a state distributed over the spacing between the two guide rails 2, 3 and which could, for example, also be configured in a structurally identical manner.

(12) The schematic illustrations according to FIGS. 2 and 3 further show a lifting drive 60. In particular, the inner door element 30 is displaceably driven along the inner guide 5 with the lifting drive 60. The lifting drive 60 has a motor 61 which is arranged in the height range of the two upper ends of the two guide rails 2, 3. The motor 61 drives a chain 62 of the lifting drive 60 which is secured to the inner door element 30, according to FIG. 3 in particular indirectly via the locking apparatus 39. In contrast, the outer door element 20 is also driven exclusively indirectly by means of the inner door element 30 with the lifting drive 60.

(13) The specific embodiment shown according to FIG. 3 makes provision for the locking element 40 to be coupled kinematically to the lifting drive 60 in such a manner that the locking element 40 in the closed position SG and when the lifting drive 60 or the chain 62 thereof is unloaded automatically takes up the blocking state S. If the lifting drive 60 is activated and the chain 62 is tensioned, the locking element 40 is unlocked.

(14) The invention is not limited to one of the above-described embodiments but instead may be modified in various manners.

(15) All of the features and advantages arising from the claims, description and drawings, including structural details, spatial arrangements and method steps, may be inventively significant both per se and in extremely varied combinations.
