DETAILED DESCRIPTION OF THE INVENTION

(16) A device 1 for storing objects comprises a first drawer element 2, which is arranged below a second drawer element 4 in a closed position. The second drawer element 4 is designed in this case as an inner drawer, which is arranged behind a front panel 3 of the first drawer element 2. By pulling on a handle element on a front panel 3, both the first drawer element 2 and also the second drawer element 4 can be moved in the opening direction. The device 1 can optionally be arranged in a domestic appliance or an item of furniture in this case, wherein each drawer element 2 and 4 is preferably movably held via two pullout guides, which are arranged on opposing sides.

(17) In FIG. 2, the first drawer element 2 has been moved into a maximally open position. The first drawer element 2 is movably held on at least one pullout guide 6, which comprises a stationary guide rail 9 fixed on a holder 5, a middle rail 8, and a slide rail 7, which are each movably mounted on one another via roller bodies. The slide rail 7 is used to support the first drawer element 2. It is also possible to use a pullout guide 6 having only two rails or more than three rails.

(18) As shown in FIG. 3, the second drawer element 4 can also be moved from a closed position into a maximally open position, wherein the second drawer element 4 is held on at least one, preferably two pullout guides 16, wherein each of these pullout guides 16 comprises a stationary guide rail 17, a middle rail 18, and a slide rail 19 for supporting the second drawer element 4. The guide rail 17 is fixed on the stationary plate-shaped holder 5, which can be secured on a side wall of a body or can also be formed as a side wall of a body.

(19) The drawer elements 2 and 4 and also the slide rails 7 and 19 of the pullout guides 6 and 16 are movable independently of one another, as shown in FIGS. 1 to 3.

(20) In FIG. 4, the device of FIGS. 1 to 3 is shown without the drawer elements 2 and 4, but looking toward the pullout guides 6 and 16, which are fixed via mounting brackets 10 on a side wall of the body 50.

(21) A cable pull 11, which is connected to a first holder 12 on the stationary guide rail 9 and to a second holder 13 on the slide rail 7, is provided on the first pullout guide 6. The cable pull 11 is held circulating via deflection rollers 14 and 15, which are rotatably mounted on the middle rail 8. It is thus ensured that the slide rail 7 is moved at twice the speed of the middle rail 8.

(22) A coupling mechanism 20 is provided between the first drawer element 2 and the second drawer element 4, which can move the second drawer element 4 during a movement of the first drawer element 2, but at lower speed than the first drawer element 2, in particular at half speed. The coupling mechanism 20 comprises a holding part 21, which is secured on the slide rail 7 of the first pullout guide 6. The holding part 21 is fixed on a cable pull 24, which is tensioned circulating between two deflection rollers 25. The deflection rollers 25 are rotatably mounted in this case on a movable rail 22, which is linearly movable in relation to a stationary rail 23. The cable pull 24 is fixed on a fastening element 26, which is directly or indirectly connected to the holder 5 or a side wall and is arranged in a stationary manner. During a movement of the slide rail 7 in the opening direction, the cable pull 24 is held by the fastening element 26 and driven by the holding part 21, so that the rail 22 moves at approximately half the speed of the slide rail 7.

(23) In FIG. 5, the device 1 is shown having the pullout guides 6 and 16 in the closed position. Both pullout guides 6 and 16 and the drawer elements 2 and 4 supported thereon in the installed situation are located inside a body 50, for example, an insulated hollow chamber of a refrigerator. A driver 30, which can be coupled to an axis 29, which protrudes laterally on the deflection roller 25, is provided on the upper second drawer element 4. If the slide rail 7 is moved out of the position shown in FIGS. 4 and 5 via the first drawer element 2 in the opening direction, the movable rail 22 is driven at half the speed of the slide rail 7 via the coupling mechanism 20 via the cable pull 24, whereby the axis 29 also drives the driver 30 at half speed. The second drawer element 4 is thus moved at half the speed of the first drawer element 2 in the opening direction and thus also over half the distance of the first drawer element 2.

(24) In FIG. 6, the slide rail 7 of the first pullout guide 6 is arranged in the maximally open position. The holding part 21 has driven the cable pull 24, and the movable rail 22 has been moved in relation to the stationary rail 23 into the end position, in which the movable rail 22 protrudes only slightly out of the body 50. The driver 30 is arranged in a coupled-in position, and the second pullout guide 16, and therefore also the upper second drawer element 4 (not shown here), is located approximately in the half-open position between the closed position and the maximally open position.

(25) If the user now wishes to obtain an access to the upper second drawer element 4, he can detach the coupling mechanism 20 and move the second drawer element 4 via the pullout guide 16 in the opening direction. The position shown in FIG. 3 is then reached, in which the second drawer element 4 is arranged essentially in front of the body 50 and the holder 5. The first drawer element 2 is then covered on the upper side by the second drawer element 4.

(26) In contrast, if the user wishes to obtain an improved access to the lower first drawer element 2, the coupling mechanism 20 can be disconnected, and the second drawer element 4 can be moved into the closed position in order to have a complete access to the first drawer element 2 from above, as shown in FIG. 2.

(27) The user can optionally also leave the coupling mechanism 20 engaged and thus also simultaneously move the second drawer element 4 by moving the first drawer element 2.

(28) The at least one first pullout guide 6 and/or the at least one second pullout guide 16 can be provided with a self-retractor, which decelerates the drawer elements 2 and 4 via a damper before reaching the closed position and then pulls them into the closed position.

(29) In FIG. 7, the coupling mechanism 20 is disconnected, and the second pullout guide 16 has been moved into the maximally pulled-out position. The driver 30, which is secured or integrally formed on the drawer element 4, has been removed from the axis 29 of the deflection roller 25, so that both pullout guides 6 and 16 are movable independently of one another.

(30) A detail view of the driver 30 is shown in FIG. 8, which is installed on the drawer element 4 on a side wall, but can also be provided at another position or can be integrally formed with the drawer element 4. The driver 30 comprises a catch receptacle 31, which is open toward the bottom and is formed essentially semicircular, wherein a starting bevel 32 is provided on both sides of the catch receptacle 31.

(31) In FIG. 9, the catch unit of the coupling mechanism 20 is shown. The deflection roller 25, which is rotatably mounted on an axis 29, is located on the movable rail 22, wherein the axis 29 protrudes laterally beyond the deflection roller 25 and can be engaged with the catch receptacle 31. The axis 29 can be moved along one of the two starting bevels 32 for a coupling of the catch unit in this case, so that the second drawer element 4 is slightly raised before the axis 29 locks in the catch receptacle 31.

(32) In FIG. 10, the driver 30 and the deflection roller 25 having the axis 29 are shown in the locked position. In this position, the drawer elements 2 and 4 are moved together at different speeds.

(33) In FIG. 11, the driver 30 is shown in the maximally pulled-out position of the movable rail 22, which only protrudes from the body 50 in the region of the deflection roller 25. In this position, the second drawer element 4 can be slightly raised in order to disengage the catch unit, as shown in FIG. 14. Optionally, unlocking of the catch unit can also be effectuated only by pulling or pushing the second drawer element 4.

(34) In FIG. 12 and FIG. 13, the second drawer element 4 is shown in a lowered position, in which an edge 42 rests on the slide rail 19. A plug 40 is inserted into the end of the slide rail 19, at which plug a lift limiting unit is provided for limiting the lift movement of the second drawer element 4. The lift limiting unit comprises an upwardly protruding web 41, on the end of which a hook 43 is formed. The web 41 encloses an edge 42 of the drawer element 4 in this case. The lift limiting unit having the web 41 and the hook 43 is shown in detail in FIG. 13.

(35) If the second drawer element 4 is slightly raised, the position shown in FIGS. 14 and 15 is reached. The edge 42 has been moved upward along the web 41, until the hook 43 prevents further raising of the edge 42 and the drawer element 4. In this position, the driver 30 connected to the drawer element 4 has also been raised and is no longer engaged with the axis 29. The slide rail 19 can thus be moved independently of the coupling mechanism 20.

(36) To engage the coupling mechanism 20 again, the first drawer element 2 and the second drawer element 4 can be moved back into the closed position, as shown in FIGS. 1, 4, and 5. By moving the first drawer element in relation to the second drawer element 4, the axis 29 reaches the starting bevel 32 and is locked in the catch receptacle 31 upon reaching the closed position, so that then upon reopening of the first drawer element 2, the coupling mechanism 20 is engaged again.

(37) In the illustrated exemplary embodiment, the coupling mechanism 20 is connected to the slide rail 7 of the first pullout guide 6. Of course, it is also possible to secure the coupling mechanism directly on the middle rail 8 of the first pullout guide 6, since it is already moved at half the speed of the slide rail 7. A holder coupled to the middle rail 8 could be engaged directly with the driver 30. However, the use of an additional movable rail 22 has the advantage of enhanced stability, in particular in the case of drawer elements 2 and 4 having greater height.

(38) The coupling mechanism 20 comprises a catch unit having a catch receptacle open toward the bottom on the upper drawer element 4, which can be engaged with an axis or a pin. Of course, it is also possible to provide the coupling mechanism 20 with other catch units, which enable a certain force transmission in the opening and closing directions between the first drawer element 2 and the second drawer element 4 and are unlockable by an actuation or exceeding a force. It is also possible to use a spring-loaded driver 30, which pivots or moves linearly for decoupling in the event of external force application in the opening or closing direction on the upper drawer element 4 and thus detaches the coupling mechanism 20 and subsequently thereto moves back into its starting position again.

(39) For unlocking, the second drawer element 4 is slightly raised in the illustrated exemplary embodiment. Of course, it is also possible to provide an actuating element, for example, a lever or a button, by means of which the catch unit is disconnectable.
