In the one shown here, in an extension direction x from a body 2 of the furniture 1 Drawer shown in extended state 3 is a storage area 4 built-in, which uses a lifting mechanism 5 from inside the drawer3 It can be raised and lowered.

[0029] The lifting mechanism 5 indicates, for example in the Fig. 7, Fig. 10 and Fig. Figure 11 shows a scissor mechanism with at least two crossed and rotatably connected scissor levers. 51 , 52 for raising and lowering the shelf 4 on.

[0030] A first scissor lever 51 is at a first end 511 stationary and rotatable on the shelf 4 arranged accordingly. A second scissor lever is also present. 52 at a first end 521 rotatable and sliding on the shelf 4 arranged.

[0031] A second ending 512 of the first scissor lever 51 It is rotatable and slidable on the drawer 3 or, as in the design variant of a piece of furniture 1 based Fig. 3 shown, on the furniture body 2of the furniture 1 arranged. A second end 522 of the second scissor lever 52 It is stationary and rotatable on the drawer. 3 or the furniture body 2 of the furniture 1 arranged.

[0032] The fixing of the lifting mechanism 5 on the drawer 3 or the furniture body 2 of the furniture 1 This is done as described in the Fig. 10 and Fig. 11 shown, by at least two mounting elements 8 and a first guide rail that can be locked into it 7 , where the second ends 512 , 522 of the first and second scissor levers 51 , 52 are determined.

[0033] Depending on the design of the storage unit 4 Is it conceivable to modify the lifting mechanism? 5 to be equipped with such a scissor mechanism. Preferably, the lifting mechanism has 5However, two parallel scissor mechanisms are used, preferably via a crossbar. 55 are interconnected and synchronized. The crossbar 55 is preferably with the second end 512 of the first scissor lever 51 connected, as exemplified in Fig. 10 can be seen.

[0034] The mounting elements 8 and the first guide rail 7 are detailed in the Fig. 12 to Fig. 14 shown. The first guide rail 7 is preferably designed as a C-profile in which at least one roller 11 is guided. The roller 11 is preferably at the second end 512 of the first scissor lever 51 Mounted. For rotatable, but stationary fixing of the second end. 522 of the second scissor lever 52 is in the guide rail 7 preferably a T-nut 12fixed, whose outer contours are attached to the inner profile of the guide rail 7 is adapted. The T-nut 12 preferably attached to the guide rail 7 screwed or riveted.

[0035] Instead of at least one roller 11 Other sliding elements or running bodies can also be used.

[0036] Each of the mounting elements 8 has a base 81 up, which land on a floor 35 of the drawer 3 or a floor 22 of the body 2 of the furniture 1 It is attached and fastened, for example by screwing, gluing, or snapping it into place. Screw holes are preferably provided for inserting screws. 84 in the base 81 of the mounting element 8 introduced. From the grassroots. 81 A roughly U-shaped profile extends vertically upwards. 82with side legs of different lengths. Alternatively, the mounting elements can be used 8 also on the side frames 32 , on the front panel 31 or on the back wall 33 They can be attached. The mounting elements can be used for this purpose. 8 It may be designed differently, for example without a base.

[0037] The longer of the side leg of the profile 82 is a resting nose 83 molded, which after the guide rail is inserted 7 a lifting upwards in one direction z by locking the guide rail 7 in the mounting element 8 prevented. It is also conceivable to have several such locking lugs. 83 on the mounting elements 8 to shape.

[0038] As in the Fig. 2, Fig. 4, Fig. 6 to Fig. 9 and Fig. 15 to Fig. As can be clearly seen in 19, the first ends are 511 , 521 the scissor lever 51 ,52 at one of the storage areas 4 lockable second guide rail 9 determined.

[0039] The first end 511 of the first scissor element 51 It is stationary and rotatable with the second guide rail 9 connected. The first end 521 of the second scissor lever 52 It is rotatable and movable with the second guide rail 9 tied together.

[0040] Connecting the first ends 511 , 521 the scissor lever 51 , 52 to the second guide rail 9 This is preferably done according to the connection of the second ends. 512 , 522 the scissor lever 51 , 52 on the first guide rail 7 . This is at the first end 521 of the second scissor lever 52 preferably a roller 11or a sliding element is attached, which is located in the second guide rail 9 is led.

[0041] The connection of the first ends 511 , 521 the scissor lever 51 , 52 with the second guide rails 9 This enables an easy connection to the storage system. 4 .

[0042] The filing 4 is preferably container-shaped, for example in the form of a wooden box with a bottom 41 and four the ground 41 surrounding side walls 42 , 43 , 44 , 45 Other containers made of steel or aluminum, or tubs made of plastic, etc., can also be used.

[0043] Training in filing is also conceivable. 4 as a basket, especially a wire mesh basket, as it is in Fig. 8 is shown, or also as a shelf base, as shown in Fig. 9 is shown.

[0044] All these design variants have in common the lateral mounting of the second guide rail. 9 , preferably via a snap-fit ​​connection to allow for the exchange of different types of trays 4 to enable this in a simple way.

[0045] To raise or lower the shelf 4 To enable this in a simple way, a lever is used. 61 and a toggle lever 53 formed knee joint 56 coupled with the scissor mechanism with which the storage 4 from a lowered position, as exemplified in Fig. 5 is shown, in an elevated position, as exemplified in Fig. As shown in section 4, it is movable. Fig. 25 is alternatively a lifting mechanism with a toggle lever 64 shown.

[0046] The filing 4 is with the help of the knee joint 56Furthermore, it can be locked in a raised position. At a free end of the swivel lever that can be pivoted by the user. 61 is a handle 62 attached.

[0047] This handle 62 can, as in the Fig. 1 to Fig. As shown in example 5, it is designed as a handle that is positioned between the pivot levers. 61 the parallel scissor mechanisms are arranged, connecting them. The handle can be used in this way. 62 on the swivel levers 61 be arranged to rotate.

[0048] It is also conceivable to use the handle 62 to be designed as a one-sided handle, preferably attached to a front panel 31 of the drawer 3 is attached to a nearby swivel mechanism. The handle can also be used here. 62 on the swivel lever 61 It must be mounted in a rotatable manner.

[0049] In one in the Fig. 15 to Fig. The preferred embodiment shown in 17 is the pivot lever. 61 in a raised position of the lifting mechanism 5 It is designed to be foldable. This has the advantage that the storage area 4 is freely accessible for loading or unloading. The swivel lever 61 with the handle attached to it 62 is done by the in Fig. Position 15 shown, in which the handle 62 vertically above the shelf 4 is positioned in a Fig. Position 16 shown is swivelled, where the handle 62 to the right or left side next to the storage area 4 is positioned. The swivel lever 61 It does not extend, or only partially extends, beyond the upper edge of the side walls. 42 , 43 , 44 , 45 the filing 4 forward and thus enables convenient loading or unloading of the storage area 4 .

[0050] The swivel lever 61In this version, it is attached to a plate-shaped locking element. 63 mounted in such a way that the pivot lever 61 It can be decoupled from the scissor mechanism. The functionality of this bearing is explained further below using the following examples. Fig. 25 to Fig. 32 explained in more detail.

[0051] To facilitate raising and lowering the lifting mechanism 5 is as in the Fig. 7, Fig. 10, Fig. 11 and Fig. 15 to Fig. 19 shown, an energy storage device 54 coupled to the scissor mechanism. The energy storage device, preferably designed as a gas pressure damper, is connected at one end to the first scissor lever. 51 and with a second end on the second scissor lever 52 fixed and thus enables a dampened movement sequence when raising and lowering the shelf 4 .

[0052] As especially in the Fig. 1 and Fig. As shown in 2, this is the lifting mechanism. 5 in the drawer 3 of the furniture 1 such a space in the drawer 3 installed so that the first guide rail 7 the lifting mechanism 5 in direction y perpendicular to the extension direction x of the drawer 3 is aligned.

[0053] As further explained in Fig. As shown in point 2, it is on a floor 22 of the body 2 of the furniture designed here as drawer furniture 1 a self-move-in 10 arranged, with a first component 101 , which is on the drawer bottom 22 is attached and to a back wall 33 of the drawer 3 attached second component 102 Self-removal 10 This serves to secure the drawer. 3 in the extended position. This prevents the drawer from 3 into the body2 can retract independently, and if necessary, with the storage compartment raised. 4 other parts of the furniture 1 or the filing 4 This can damage the drawer. Retracting the drawer 3 This is only possible through an active insertion movement.

[0054] To prevent fingers or a user's hand from being pinched when operating the lifting mechanism or using the tray, at least one side surface of the tray must be protected. 4 a pinch protection 13 with at least one protective element that can be moved in the direction of lifting z 131 , 132 arranged 13 is exemplary in the Fig. 18 to Fig. 20 shown.

[0055] The pinch protection 13 has at least two edges of the storage area, each located on an edge extending in the direction of lifting z. 4 attachable housings 14 each of these cases 14indicates how in Fig. 19 shows guide grooves extending in the direction of travel z and open to each other. 143 , 144 on, in each of which one of the protective elements 131 , 132 is led. In the Fig. 18 and Fig. In the embodiment shown in Figure 19, there are two such guide grooves. 143 , 144 on the case 14 molded in. However, it is also conceivable to have three or more, or even just one, such guide groove on the housing. 14 to shape.

[0056] To limit the displacement in the stroke direction z, the housing 14 into the displacement path of the protective elements 131 , 132 sufficient advantages 145 arranged as shown in the two illustrations according to Fig. 20 is shown. Accordingly, the protective elements 131 , 132at their upper ends they have respective projections which, upon reaching a final position on a respective ledge 145 resting on top of each other and preventing further shifting or sliding of the protective elements 131 , 132 impede.

[0057] For mounting the housings 14 at the storage area 4 Fixing elements, in particular screws or bolts, 142 are provided, which are arranged on a region of the housing, which is L-shaped in cross-section here, angled away from the grooves and which, in the state mounted on the shelf, as is the case, for example, in the Fig. 6 and Fig. As shown in section 7, on side walls 42 , 44 the filing 4 are specified that are not affected by the protective element(s). 131 , 132 are hidden.

[0058] As in the Fig. 6 and Fig. 7, which is also recognizable, covers the protective element at the top. 131 the side walls 43 and45 the filing 4 , while the lower protective elements 132 downwards into the receiving space of the drawer 3 extend and thus allow intervention between the upper edge of the side frame 32 of the drawer 3 and the lower edge of the side walls 43 , 45 the filing 4 impede.

[0059] It is also conceivable to use the upper protective element 131 as a side wall 43 the filing 4 to use, so that in this case the second protective element 132 in the cases 14 The tray can be moved and guided when being lifted. 4 using the scissor mechanism, it slides downwards against the direction of the stroke z and then lowers the tray again. 4 in the guide grooves 143 , 144 guided again over the upper protective element, which is used here as a side wall. 131 is being pushed.

[0060] As in the Fig. 21 and Fig. As shown in 22, it is also conceivable to design one of the scissor levers so broadly to form a pinch protection mechanism that the storage area 4 removed scissor levers, in the example shown the first scissor lever 51 , is formed in a central area with a flat surface, so that the surface of the scissor lever covers at least 30% of the area spanned by the scissor levers and thus provides reliable pinch protection, effectively preventing the pinching of a user's fingers.

[0061] Otherwise, the item can be removed from the storage area. 4 removed scissor levers 51 also with a cover element 58 It must be equipped to prevent a user's fingers from becoming trapped, as can happen, for example, in the Fig. 4 and Fig. Figure 6 shows the cover element. 58Can be removed without tools, e.g. by clipping, or with fasteners that can be removed or removed permanently using the scissor lever. 51 be connected.

[0062] Based on the Fig. 23 to Fig. 30 below describes a variant of the lifting mechanism. 5 described, in which the swivel lever 61 with the handle attached to it 62 , with which the filing 4 or the scissor mechanism can be raised and lowered via a locking element 63 It can be coupled and uncoupled with the scissor mechanism.

[0063] The storage area is 4 with the swivel lever 61 adjustable in a coupled lifting and lowering position from a lowered position to a raised position, while the swivel lever 61 It can be folded in a folding position decoupled from the scissor mechanism without any further movement of the scissor mechanism.

[0064] Fig. Figure 23 shows the lifting mechanism 5 with the storage 4 in a lowered position of the storage area 4 , as it is taken, for example, when the filing 4 in a drawer 3 lowered and the drawer 3 into the furniture body 2 of the furniture 1 is inserted.

[0065] As shown in the detailed description in Fig. The lever shown in 24 is the pivot lever. 61 In this version, it is not directly connected to the scissor mechanism, but via a locking element. 63 .

[0066] The locking element 63 is as in Fig. 30 exemplified, via a side wall of the storage unit 4 fixed swivel joint 68 with the swivel lever 61 tied together.

[0067] The pivot joint 68 features a pivot bolt 681 on, which passes through a slotted hole 611of the swivel lever 61 guided and in a bore 634 of the locking element 63 has been recorded.

[0068] The locking element 63 It is designed here as a flat element, with a locking groove 631 , in which, in the coupled lifting and lowering position, a swivel lever 61 fixed stopper 66 is recorded. The stopper 66 is preferably bolt-shaped and is perpendicular to the longitudinal extent of the pivot lever. 61 from one of the storage 4 opposite side surface of the pivot lever 61 in the direction of the locking element 63 before.

[0069] As in Fig. The stopper is shown as 30. 66 in an imaginary extended line of the longitudinal extent of the elongated hole 611 on one of the handles 62 far end of the pivot lever 61 positioned.

[0070] Between the pivot lever 61 and the locking element 63 A washer is also preferred. 682 arranged to facilitate the easier pivoting movement of the pivot lever 61 relative to the locking element 63 serves.

[0071] As in Fig. 24 can also be seen from the locking element 63 a feather 67 specified, which is one end of the stopper 66 includes and thus the stopper 66 without external force in its coupled position in the locking groove 631 holds.

[0072] On the locking element 63 Furthermore, as in Fig. 24 is clearly recognizable, a lever 64 rotatably fixed, its second end attached to the second scissor lever 52 is fixed in a rotatable position. The lever 64 It can serve as a tow lever for the lifting mechanism. Furthermore, it forms an end of the energy storage system. 54at the locking element 63 fixed. Finally, the locking element is 63 with an extension piece 65 of the first scissor lever 51 rotatably connected.

[0073] Fig. Figure 25 shows the position of the swivel lever. 61 , where the storage 4 is in its raised position. The swivel lever 61 It is essentially positioned vertically upwards in the Z-direction of travel. As shown in the detailed illustration in Fig. The stopper can be seen from number 26. 66 in this position still in the locking groove 631 of the locking element 63 recorded.

[0074] To the swivel lever 61 to decouple it from the scissor mechanism is, as in Fig. 27 shown, the swivel lever 61 The stopper is pressed vertically downwards by a user, in the opposite direction of the stroke Z. 66 through the elongated hole 611in the pivot lever 61 enabled movement out of the locking groove 631 moved out and can now move further without moving the scissor mechanism into the Fig. The position shown in 28 can be folded down. In this position, the swivel lever 61 folded into an approximately horizontal position, in which the swivel lever 61 and the handle attached to it 62 no longer above, but essentially next to the storage area 4 is positioned.

[0075] To limit the lateral folding movement, as shown in the detailed illustration in Fig. 29 is shown, an attack 632 at the locking element 63 arranged, to which the stopper 66 strikes when the swivel lever 61 the in Fig. The folded-over position shown in section 28 has been reached.

[0076] To decouple the swivel lever 61 The pivot lever is part of the scissor mechanism. 61oriented in such a way that the longitudinal extent of the elongated hole 611 parallel to the locking groove 631 stands.

[0077] In the Fig. 31- Fig. Figure 35 shows two further design variants. In these designs, the guide rails extend 7 in the drawer 3 across the entire width of the drawer 3 .

[0078] The width of the shelf 4 is significantly smaller than the width of the drawer 3 .

[0079] A second ending 522 of the second scissor lever 52 the lifting mechanism with which this storage unit 4 in the drawer 3 The fixed position can be detached from the first guide rail. 7 fixed. The resolvable fixing of the second end. 522 of the second scissor lever 52 This is done, for example, via a clamping screw. 523 , as in Fig. 34 and in the detailed presentation in Fig. 35 is shown. The clamping screw 523 is into an opening at the end of the second end 522 of the second scissor lever 52 screwed in, thus securing the second end 522 of the second scissor lever 52 friction-fit to the guide rail 7 .
