Description

Technical Field

[0001] The present invention relates to a pull-out cabinet unit, in particular for a tall cabinet, which has a frame to be arranged in the inner space of a basic cabinet structure, wherein the frame carries a cabinet door or a similar cabinet cover on a longitudinal beam at the front, wherein the frame carrying each supporting base plate can be translated from a first operating position located inside the basic cabinet structure to a second operating position located in front of the basic cabinet structure, and wherein the frame with upper and lower pull-out rails can be moved to the second operating position by means of a rear vertical longitudinal beam in such a way that the pull-out cabinet unit can be pivoted around a vertical pivot in the second operating position.

[0002] In this case, the pull-out cabinet unit is assigned a locking device which prevents a pivoting movement of the frame before reaching the second operating position and releases the pull-out cabinet unit for a pivoting movement in the second operating position. Background Art

[0003] In the case of the well-known high cabinets known as lockers, the load-bearing parts, which are guided to the middle longitudinal plane of the basic cabinet structure by pull-out rails or the like, are constructed as a frame that is as closed as possible, and the individual support bases are held between the vertical longitudinal beams of this frame, thereby ensuring accessibility of these support bases from both sides in the second operating position as the fully pulled-out position. In order to remove objects from the opposite areas of the support base, the operator needs to walk around the pull-out cabinet unit in the second operating position in addition, so that, especially when the support base is fully loaded, it takes more time to ensure trouble-free removal. An example of such a cabinet with a corresponding pull-out device is known from EP 1 479 318 B1.

[0004] Furthermore, EP 1 820 422 discloses a pull-out cabinet unit of the type mentioned at the outset for a cabinet, wherein a locking device is additionally provided, which has a locking lever that can be pivoted about a horizontal axis, and which locks a first extension rail in the extension direction and a second extension rail in the extension direction together so that during the translational extension movement, the frame is firmly held in its position parallel to the extension rails for the translational extension movement without interference. However, in order to unlock the locking lever of the locking device, a relatively heavy component is required in order to be able to release the frame for the pivoting movement. Furthermore, this requires an increased level of operating difficulty.

[0005] WO 2007 / 000785 A1 also discloses a pull-out cabinet unit for a tall cabinet, wherein, similar to the aforementioned EP 1 479 318 B1, a largely closed frame is provided, which has a front vertical longitudinal beam and a rear vertical longitudinal beam, and which can be moved by upper and lower pull-out rails that are telescopically engaged with each other to a position located in the tall cabinet and to a fully pulled-out position pulled out of the cabinet body, so that in order to remove objects from the opposite area of ​​the support base, the operator must walk around the pull-out bracket. Therefore, even when using such a pull-out bracket, it takes more time to remove the stored objects without any problems. Summary of the invention

[0006] The object of the invention is to further develop a pull-out cabinet unit of the type mentioned in the introduction in such a way that the frame in its second operating position can be pivoted reliably into an operating position, but only a small number of components are required for this purpose at low cost.

[0007] In order to achieve the above-mentioned purpose, the pull-out device of the pull-out cabinet unit of the type described in the opening paragraph is characterized in that the locking device has a guide rail component including a guide rail that can be pivoted around a vertical axis, and the guide rail component can be moved to a second operating position together with the frame, wherein during part of the pivoting movement, the guide component of the frame is guided in the guide rail of the guide rail component, and wherein during the translation of the frame to the second operating position, the guide rail component is arranged in the locking device to prevent pivoting movement.

[0008] This provides a pull-out cabinet unit, wherein the frame of the pull-out cabinet unit together with the supporting base and the objects stored thereon can be safely moved out of the interior of the basic cabinet structure until it is in the second operating position (fully extended position). Further relative movement of the first extension rail in the extension direction and the frame supported thereon relative to the extension rail located downstream in the extension direction can automatically release the locking device, the guide rail part, and thus the frame so that it can be pivoted about the vertical axis.

[0009] In this case, the pin-shaped guide part preferably snaps into the guide rail of the guide rail part, so that the pivoting movement is positively controlled thereby. After the first part of the pivoting movement to the fully operating position perpendicular to the pull-out rail has been completed, the guide part can leave the guide rail and automatically move into this guide rail again after pivoting back until this guide part reaches a position parallel to the pull-out rail. For this purpose, special locking parts can be provided, which have corresponding grooves and protrusions so that they can be snapped into place, thereby reliably moving the frame and the pull-out rail back again into the first operating position, in which the frame is located inside the basic cabinet structure.

[0010] The telescopic pull-out unit is preferably constructed as a component of a pull-out cabinet unit, which has three pull-out rails in a relatively inexpensive structure, namely in the lower and upper regions of the cabinet, wherein the guide rail components together with the guide rails can be arranged at the bottom or top of the upper or lower pull-out rail region of the pull-out cabinet unit. The locking device can also be part of the first pull-out rail, but can also be part of the second pull-out rail (i.e., the middle rail), which is located between the first pull-out rail in the pull-out direction and the third pull-out rail in the pull-out direction, which is fixedly fixed to the basic cabinet structure.

[0027] In the drawings, substantially the same components are provided with the same reference numerals.

[0028] The tall cabinet is generally designated by 1 and has a basic furniture structure 2 and a cabinet cover 3, so that the tall cabinet is constructed in the form of a storage cabinet. The cabinet cover 3 is held by a frame generally designated by 4, which has two vertical longitudinal beams 5 and 6, wherein the cabinet cover 3 is held by the vertical longitudinal beam 6 ( Figure 2 ). The supporting base plate 7 is held between the vertical longitudinal beams 5 and 6.

[0029] The frame 4 has an upper extension rail 8 and a lower extension rail 9 which together with the vertical longitudinal beams 5 , 6 form the frame 4 in the form of a rectangular frame.

[0030] In order to extend the frame 4, a telescopic extension unit is provided, which has a total of three extension rails 9.1, 9.2 and 9.3, wherein a first extension rail 9.1 in the extension direction can be moved relative to a second (middle) extension rail 9.2 in the extension direction, and this second extension rail can in turn be moved relative to a third extension rail 9.3 in the extension direction which is fixedly mounted in the basic cabinet structure 2. The extension rails 9.1, 9.2 and 9.3 can be used for the lower extension rail 9 of the frame 4 and the upper extension rail 8 of the frame 4.

[0031] The lower pull-out rails 9.1, 9.2 and 9.3 are connected by means of gears 10 and Fig.10 The teeth 11 and 12 shown are forced to synchronize. Figure 4 , 5 , 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 17 and 18 show in detail that the frame 4 is supported on a first pull-out rail 9.1 in a manner that it can be pivoted about a vertical axis. A locking device 13 is provided on the second pull-out rail 9.2, which locking device consists of two bent side feet that are aligned with each other and are clamped on the second pull-out rail 9.2. The two side feet have an intermediate or through-gap 13.1 in the area of ​​the ends facing each other, wherein the ends of the two side feet of the locking device 13 that delimit the through-gap 13.1 facing each other form a stop for a guide rail part 14, in which a guide rail 15 for a guide part 16 is embedded, which is arranged on the lower pull-out rail 9 of the frame 4 ( Figure 7 ).

[0032] In accordance with Figure 5 and Figure 6 In the illustration of FIG. 1 , the guide rail part 14 is still located in the through-opening 13.1 of the locking device 13, so that the frame 4 cannot be pivoted. However, if the frame reaches the fully extended position, i.e. the second operating position, the guide rail part 14 can leave the locking device 13 and can be caused to pivot together with the extension rail 9 and thus together with the frame 4 by means of the guide part 16 (drive element) which can be moved in the guide rail 15 ( Figure 7 ).like Figure 7 , 8 As shown in FIGS. 9 and 10 , after the first part of the pivoting movement is completed, the guide member 16 leaves the guide rail 15, wherein specifically depending on whether the frame 4 is pivoted clockwise or counterclockwise, it can occupy a position between Figure 8 and 9 Two positions are shown.

[0033] Furthermore, a locking element 18 is provided, which cooperates with a locking device 19 which is fixed to the first extension rail 9.1 in the extension direction and which fixes the frame 4 in parallel with the extension rails 9.1, 9.2, 9.3 during the movement from the first operating position to the second operating position. For this purpose, the locking element 18 has three locking projections 18.1, 18.2, 18.3 of the locking device 19 for the frame 4. The locking device 19 has corresponding recesses.
