DETAILED DESCRIPTION OF THE INVENTION
[0040] In FIG. 1 a perspective view of an item of furniture 14in this case with two drawers 4is shown. The two drawers 4 are linearly movable supported on a furniture carcass 7 by way of an extension guide (not illustrated here). The upper drawer 4 is situated in an open position OS, whereas the lower drawer 4 is situated in a closed position SS. Each drawer 4 comprises a front panel 15, a drawer back wall 16, two drawer side walls 12 (with a bearing web 2 each) and drawer base 3.
[0041] FIG. 2 schematically shows a section through the drawer 4. This section runs parallel to the front side of the front panel 15. In this section the drawer base 3 is illustrated as a flat plank. In this case, the bearing webs 2 are formed in one piece with the profile-shaped drawer side wall 12. Drive devices 6 (preferably ejection devices) are arranged on the bottom side of the drawer base 3 on both lateral sides. Movements of these drive devices 6 can be synchronized by the synchronizing rod 17 (illustrated with a dashed line). In previously known variants, these drive devices 6 are each attached by (plate-shaped) holding devices 5 on the bottom side of the drawer base 3 or in the region of the bearing web 2.
[0042] A securing variant according to the prior art is illustrated schematically in FIG. 3. In this variant the drawer base 3 is resting on the bearing region A of the bearing web 2 in a flush manner. A lug-shaped receiving area 9 is formed in the region of the bearing web 2, The holding device 5 (together with the drive device 6) is secured in the receiving area 9 by way of the securing element 8 in a clamped manner. The support surface S of the securing element 8 facing towards the drawer base 3 rests in a clamped manner on a surface of the bearing web 2 which is remote from the drawer base 3, In this illustration it is visible that the securing region is relatively thick.
[0043] In contrary, in FIG. 4 the securing variant according to the present invention is illustrated schematically. Also here, the drawer base 3 is resting on the bearing region A of the bearing web 2. The bearing web 2 comprises a receiving area 9 for the securing element 8 of the holding element 5, the receiving area 9 being arranged adjacently to the bearing region A. In the illustrated secured state BZ the securing element 8 is held in a clamped manner between the drawer base 3 and the receiving area 9. The support surface S of the securing element 8, here, directly contacts the drawer base 3. The support surface S of the at least one securing element 8 together with the at least one bearing region A of the bearing web 2 form a substantially flat drawer base bearing surface E for the drawer base 3. Put in other words, in the secured state BZ the support surface S and the bearing region A are arranged in the same horizontal plane. The drawer base 3 rests against the drawer base bearing surface E in a flush manner. As can be seen well in a comparison of the FIGS. 3 and 4, the securing region in FIG. 4 is formed thinner by a third approximately.
[0044] FIG. 5 shows a holding device 5 together with a drive device 6 and a bearing web 2 according to the prior art. In the lower image a view of the drawer base 3 from below is illustrated. Two lug-shaped receiving areas 9 are formed on the bearing web 2. The tongue-shaped securing elements 8 of the holding device 5 are inserted into these lug-shaped receiving areas 9. The lug-shaped bent region of the receiving areas 9 is visible particularly well in the section A-A. This section runs parallel to a lateral surface of a drawer side wall. The drawer base 3 rests against the bearing region A of the bearing web 2. In the zoomed details illustrated top left and top right, it is apparent that the securing elements 8 are intruding into the recess of the receiving area 9, wherein the support surface Smeasured rectangular to the longitudinal extension L of the metal sheet of the bearing web 2is distanced from the bearing region A. It is apparent that the recess for the receiving area 9 hat to be quite large.
[0045] In contrary, an exemplary embodiment of the present invention is illustrated in FIG. 6. In the bottom region, again, a view from below in the direction of the drawer base 3 is illustrated. The section B-B illustrated above runs parallel to a lateral surface of the drawer side wall 12. It is apparent from section B-B that the drawer base 3 rests in a flush manner against the bearing web 2. The holding device 5 for the drive device 6 is inserted into both receiving areas 9 of the bearing web 2 by way of both securing elements 8. The clamping elements 10 provide for an even better hold. In each of the zoomed details top left and top right the bearing region A of the bearing web 2 is apparent, wherein the drawer base 3 rests on this bearing region A. The receiving area 9 comprises a recess which is leading away from or which is separate from the bearing region A. The securing element 8 is intruding into this recess of the receiving area 9. The support surface S of the securing element 8 facing towards the drawer base 3 together with the bearing region A of the bearing web 2 from the substantially flat drawer base bearing surface E. In addition, the securing element 8 comprises a holding surface H which is remote from the support surface S. In the secured state BZ this holding surface H rests against the counter holding surface G of the receiving area 9. This counter holding surface G and the holding surface H are oriented parallel to the bearing region A. The bearing web 2 is formed as a metal sheet, wherein the receiving area 9 is bent out of this metal sheet as a recess. The bearing web 2 has a sheet thickness D.sub.2 of about 0.8 mm. The holding device 5 and its securing element 8 are also formed as a metal sheet. This holding device 5 has the sheet thickness D.sub.5. This sheet thickness D.sub.5 is approximately as thick as the sheet thickness D.sub.2 of the bearing web 2. As particularly well apparent from both details, the counter holding surface G of the receiving area 9measured rectangular to the longitudinal extension L of the metal sheetis distanced by the sheet thickness D.sub.2 from the bearing region A. In addition, it is clearly apparent that in the secured stated BZ the securing element 8 and the receiving area 9 togethermeasured rectangular to the longitudinal extension L of the metal sheethave a thickness which is twice as large as the sheet thickness D.sub.2 of the bearing web 2. Only in the section B-B it is apparent that each of the clamping elements 10 has a clamping surface K facing towards the drawers base 3. These clamping surfaces K rest on a counter clamping surface M of the bearing web 2, which counter clamping surface M is remote from the drawer base 3.
[0046] FIG. 7 shows an arrangement 1 together with an extension guide 18 in a perspective illustration. The arrangement 1 comprises the holding device 5 for the drive 6 and the bearing web 2 for the drawer base 2. The bearing web 2in this caseis part of a profile-shaped carrier device 13 for a drawer side wall 12 (not illustrated). This carrier device 13 can also be denoted as container rail and forms a lateral frame part of the drawer 4. The extension guide 18 comprises a drawer rail 19 and a carcass rail 20. Also a central rail can be provided when the extension guide 18 is formed as a full extension slide. The carrier device 13 is detachably connected to the drawer rail 19. In the illustration according to FIG. 7, the securing elements 8 (concretely in form of a first securing element 8.1 and a second securing element 8.2) and its supporting surfaces S are apparent well. In addition, the bearing region A of the bearing web 2 for the drawer base 3 (not illustrated) is apparent. The drawer base 3 can be fixedly connected by not illustrated securing members (e. g. screws) to the bearing web 2 by way of the recesses 21 formed in the bearing web 2. In this view the clamping elements 10 are situated below the bearing web 2. By way of the clamping elements 10 the holding device 5 can also be secured to the bearing web 2 without the drawer base 3 as the, preferably tongue-shaped, clamping elements 10 and the securing elements 8 quasi tongs-like clamp the bearing web 2. If no clamping elements 10 are provided, the mounting of the drawer base 3 is necessary for a secure mounting.
[0047] The securing movement of the holding device 5 is illustrated in FIGS. 8 to 10.
[0048] According to FIG. 8 the (left-sided) first securing element 8.1 is initially inserted with the nose-shaped protrusion 22 into the (left-sided) first receiving area 9.1. As a consequence, the holding surface H of the first securing element 8.1 remote from the drawer base 3 reaches contact with the counter holding surface G of the first receiving area 9.1 facing towards the drawer base 3.
[0049] In FIG. 9 the holding device 5 has swivelled further so that also the clamping surface K of the (left-sided) first clamping device 10.1 reaches contact with the counter clamping surface M of the bearing web 2. In the details illustrated on the right side it is apparent that the (right-sided) second clamping element 10.2 comprises a recess 23. An elevation 24 leading away from the bearing region A is correspondingly formed on the bearing web 2. Both clamping elements 10.1 and 10.2 are each connected by way of a bent region 11 with the drawer base resting region 5b of the holding device 5.
[0050] In FIG. 10 the holding device 5 is completely clamped to the bearing web 2. The secured state BZ is reached. This means, the holding surface H of the first securing element 8.1 rests against the counter holding surface G of the first receiving area 9.1 and the holding surface H of the second securing element 8.1 rests against the counter holding surface G of the second receiving area 9.2. In the right detail of FIG. 10 it is apparent that the elevation 24 in the bearing web 2 is intruding into the recess 23 (not visible here) in the second clamping element 10.2. Thereby, a particularly secure hold is reached.
[0051] In FIG. 11 the arrangement 1 is perspectively illustrated from below. The same arrangement 1 is illustrated in FIG. 12 in a plan view from below. In these illustrations the drawer base 2 is also connected to the bearing web 2, wherefore the mounting state MZ is given. The holding device 5 comprises a substantially flat drive device mounting region 5a and a substantially flat drawer base resting region 5b as well as the two securing elements 8.1 and 8.2. The drive device 6 is, preferably detachably, mounted to the drive device mounting region 5a. It is well apparent in FIG. 11 that both receiving areas 9.1 and 9.2 are lug-shaped. In FIG. 11 it is also apparent that the elevation 24 is protruding through the recess 23 of the second clamping element 10.2. Both clamping elements 10.1 and 10.2 each rest via the clamping surfaces K against the counter clamping surfaces M of the bearing web 2 (hidden by the clamping elements 10.1. and 10.2). The securing of the holding device 5 can be carried out before the mounting of the drawer base 3 (see FIGS. 7 to 10). Preferably, however, it is provided that the securing of the holding device 5 is carried out only when the drawer base 3 is mounted to the bearing web 2.
[0052] Finally, FIG. 13 shows in a front view the holding device 5 together with the drive device 6 and the drawer base 3. It is well apparent that a bend 5c is formed between the drive device mounting region 5a and the drawer base resting region 5b. This bend 5c is formed in such a way that the drive device mounting region 5a is bent in the direction of the drawer base 3 relative to the drawer base resting region 5b in an angle region a between 1 and 15, preferably between 3 and 5. In concrete, there is an angle of 4 approximately. As a consequence, the drive device 6 is pressed onto the drawer base 3. This leads to a vibration-free hold and to little space requirement.
