DETAILED DESCRIPTION
(23) The perspective view of a cabinet shown in FIG. 1a shows a cabinet shutter 1 split in two or in two parts, in the closed state. It is possible to open the cabinet at least partially by pressing on a first shutter part 3, as a result of which that shutter part is moved frontally outward in a plane P parallel to the second shutter part 2, as FIG. 1b shows. The second shutter part 2 then remains in its closed position. After the first shutter part 3 has been moved outward, it can be slid outward, over the second shutter part 2, as a result of which an opening in the middle of the cabinet becomes visible. FIGS. 2a and 2b illustrate this procedure.
(24) As can be seen in FIGS. 3a and 3b, a full opening of the cabinet is possible by an ensuing rotation of the second shutter part 2 about an axis of rotation D relative to the cabinet. The procedure of sliding and rotating the shutter parts 3 and 2 can also take place in reverse order. Naturally, it is also possible, instead of the two-sided opening shown, to open only one side of the cabinet by the above-described mechanisms, or to perform only sliding of the first shutter part 3, or only a rotation of the second shutter part 2, without first sliding the first shutter part 3. FIGS. 4a and 4b illustrate this.
(25) In FIG. 4b, the inner guide of the first shutter part 3 on the second shutter part 2 can be seen. Here, two guide means 6, embodied as inner guide rails 6, are secured to the inner side of the second shutter part 2, and the inner guide rails 6 are at least partially covered by a covering 5. With the aid of a spring-loaded outward thrusting mechanism 4, the first shutter part 3 can be moved into the parallel plane P.
(26) FIG. 5a shows the shutter parts 2 and 3 located next to one another and the inner guide rails 6 that are not connected to the shutter parts. An outward thrusting mechanism 7 is located between the inner guide rails 6, on their end remote from the axis of rotation D. The outward thrusting mechanism 7 can be connected to the covering 5 via first corners of two parallelogram-like movable connecting parts 8, which covers the connecting parts completely. The first shutter part 3 or the outward thrusting mechanism 7 have the outward thrusting mechanism 4, which cooperates with the covering 5. FIG. 5b shows the shutter parts 2 and 3, the outward thrusting mechanism 4, the covering 5, and the inner guide rails 6 in the state in which they are connected to one another.
(27) FIG. 6 shows the shutter parts 2 and 3 secured to the cabinet carcass and located next to one another, inner guide rails 6 that are connected to the shutter parts and that can each be pulled out in three parts, the outward thrusting mechanism 7, and the connecting parts 8, which are now connected to the first shutter part 3 by their first corners facing away from the covering. What can also be seen is the outward thrusting mechanism 4, connected either to the first shutter part 3 or the outward thrusting mechanism 7, and the unmounted covering 5. The part of the inner guide rail 6 located closest to the axis of rotation D is connected here to the second shutter part 2, and the part of the inner guide rail 6 that is farthest away from the axis of rotation D is connected to the covering 5.
(28) FIG. 7a shows further details of the inner guide, with the covering 5 not shown. In addition to the shutter parts 2 and 3, the inner guide rails 6, the outward thrusting mechanism 7 and connecting parts 8, a connecting rail 9 is shown as a component of the outward thrusting mechanism 7; this rail serves both as a connecting member for the connecting parts 8 located movably thereon and as a latching mechanism. In this position of the connecting parts 8, the legs of the first corners of the connecting parts 8, which are connected to the first shutter part 3 and the covering 5, respectively, have obtuse angles. The two other legs of the two corners, which are connected movably to the connecting rail, have acute angles. Also shown are a locking bar 10 and a locking element 11 connected to the second shutter part 2 as well as a guiding terminal-position keeper 12. The locking bar 10 has inclined oblong slots 13 on its two ends, parallel to the inner guide rail 6 and/or covering 5. If the shutter parts 2 and 3 are located next to one another, one end of the connecting rail 9 is located next to a first end, farthest away from the axis of rotation D, of the locking bar 10; these are parts of a first latching mechanism. Two bolts, which are located on the part of the inner guide rail 6 and/or of the covering 5 farthest away from the axis of rotation D, engage the oblong slots 13 and are located on the ends, remote from the axis of rotation D, of the oblong slots 13. Since the inclined paths of the oblong slots 13 at this location are located in the direction of the side of the locking bar 10 oriented toward the covering 5, the locking bar 10 is moved in the direction of the shutter parts 2 and 3, and a second end of the locking bar 10 engages a locking element 11 secured to the inside of the second shutter part 2, which are parts of a second latching mechanism. The combination of the first and second latching mechanism prevents sliding of the first shutter part 3 relative to the second shutter part 2. As is known from FIG. 1a and shown in FIG. 7b, the outward thrusting mechanism 4 is actuated by pressure on the outside of the first shutter part 3; this outward thrusting mechanism can be locked on the covering 5 and/or is braced thereon and can assume a state that is lockable and is either swung closed or open. Since the outward thrusting mechanism 4 is spring-loaded and is connected to the outward thrusting mechanism 7, the latter is now actuated by means of the spring force, as a result of which the outward thrusting mechanism 7 moves to its operative position, and the first shutter part 3 assumes a position relative to the second shutter part 2 that is offset into a parallel plane. The end of the connecting rail 9 located, in a position of repose of the outward thrusting mechanism 7, beside the first end of the locking bar 10 is thereby moved behind the locking bar 10. As a result, an initial sliding of the first shutter part 3 over the second shutter part 2 is made possible. In this position of the connecting parts 8, the legs of the first corners of the connecting parts 8, which are connected to the first shutter part 3 to the covering 5 now have acute angles. The other two legs of the second corners, which are movably connected to the connecting rail, now have obtuse angles. At the beginning of the sliding motion, the bolts are moved, in the inclined paths of the oblong slots 13, in the direction of the ends of the oblong slots 13 that are located closest to the axis of rotation D. These ends are located in the direction of the side of the locking bar 10 that faces away from the covering 5, as a result of which the locking bar 10 is moved away from the shutter parts 2 and 3, and as a result of which the second end of the locking bar 10 is moved out of the locking element 11.
(29) FIGS. 8a and 8b show the further course of the sliding procedure. Upon reaching the terminal position of the sliding procedure, the end of the locking bar 10 located closest to the axis of rotation D is locked by a guiding terminal-position keeper 12, as a result of which the first shutter part 3 is kept parallel over the second shutter part 2. The guiding terminal-position keeper 12 can be based on a magnetic and/or mechanical principle of operation. Sliding the first shutter part 3 back into its position located next to the second shutter part 2 is first accomplished by undoing the locking counter to the magnetic and/or mechanical holding force of the guiding terminal-position keeper 12 and by then sliding it further as far as the lateral end position of the shutter part 3 and pressing on the shutter part 3, as a result of which that shutter part is brought next to the shutter part 2. The outward thrusting mechanism 4 is in the process locked on the covering 5 again, and the two latching mechanisms described above lock the two shutter parts 2 and 3.
(30) FIGS. 9a through 9c again in detail show the function of the first latching mechanism. In FIG. 9a, the end of the connecting rail 9 is located next to the first end of the locking bar 10, as a result of which the shutter parts 2 and 3 are locked next to one another. In FIG. 9b, the first shutter part 3 is shifted into a plane that is parallel to the second shutter part 2, as a result of which the end of the connecting rail 9 is located behind the first end of the locking bar 10, and as a result, a first lateral sliding of the shutter parts 2 and 3 relative to one another is made possible. In FIG. 9c, the first lateral sliding is performed, and the end of the connecting rail 9 is now located directly behind the first end of the locking bar 10, and as a result a parallel reverse shifting of the shutter part 3 into the plane of the shutter part 2 is prevented.
(31) FIGS. 10a through 10c again show in detail the function of the second latching mechanism. In FIG. 10a, the shutter parts 2 and 3 are located next to one another. In this position, bolts, not shown, which are located on the part of the inner guide rail 6 and/or of the covering 5 located farthest away from the axis of rotation D, on the end of the oblong slots 13 located farthest away from the axis of rotation D, and engage these oblong slots. Since the inclined paths of the oblong slots 13 at this site are located in the direction of the side of the shutter parts 2 and 3 oriented toward the covering 5, the locking bar 10 is moved in the direction of the shutter parts 2 and 3, and the second end of the locking bar 10, with a region 14 that is at an angle of 90° and protrudes past the locking bar 10, engages a locking element 11 that is secured to the inner side of the second shutter part 2. FIG. 10b shows the situation at the end of the first lateral sliding procedure, in which the bolts have moved along the inclined paths of the oblong slots 13 to the end of the oblong slots 13, which are located closest to the axis of rotation D, as a result of which the angled region 14 is moved out of the locking element 11 and enables a further sliding of the first shutter part 3 over the second shutter part 2, as is shown in FIG. 10c.
