(22) FIG. 1 shows in partial perspective how a side wall of the drawer is embodied. It includes a front fixation unit FE with an insertion receptacle EFA for the coupling bolt 11 on the back side of the facing B. The front fixation unit FE is accommodated in a housing G, which can be fastened with a tab L that has fastening bores c to the side edge, facing toward it, of the drawer bottom SB. A wooden casing adapter AD is introduced with bolts a into bores b of the wooden casing portion SWA and firmly connected, for instance glued, firmly to it.

(23) The drawer thus prepared is shown in FIG. 2; the housing G with the front fixation unit FE and the wooden casing portion SWA form the side wall of the drawer, which is firmly connected to the drawer bottom SB, for instance being glued or screwed to it, as FIG. 3 shows. The housing G with the front fixation unit FE is flush with the open face end of the drawer. The facing B now needs only to be aligned, with its coupling bolts 11, with the insertion receptacles EFA of the front fixation units FE and pushed in. All the other functions are taken on by the front fixation units FE, as will be shown hereinafter. Since the other side wall is constructed similarly but laterally reversed, the vertical adjustment elements 9 and the lateral adjustment elements 10 are accessible in the housing G via the recesses A. In the final inserted position of the drawer, the facing can thus be aligned exactly, so that in the furniture carcass it presents a visually clean image for the front side of the piece of furniture.

(24) As FIG. 4 shows, the front fixation units FE, after the alignment of the facing B, are covered with masking caps AK, which are flush with the outer cross sections of the wooden casing portions SWA and the open face end of the drawer. The housing G of the front fixation unit FE has stamped-out tabs L, which when the housing G has been thrust onto the wooden casing adapter AD are bent into receptacles d of the wooden casing adapter AD and thus establish a firm connection of the housing G with the front fixation unit FE and the wooden casing portion SWA (FIG. 2).

(25) In FIG. 5, a fitting part for the drawer is shown in perspective; the view is directed to the fastening side, facing toward the side wall of the drawer. The facing fitting 5 is screwed via the bores 5b to the back side of the facing. The coupling bolt 11 connects the two legs of the facing fitting 5, embodied in bracket-like form, in a predetermined spacing from the back side of the facing. The facing of the drawer has two such facing fittings at a spacing which is adapted to the size of the face ends of the two side walls of the open face end of the drawer having the front fixation units FE.

(26) FIG. 6 shows the two fitting parts in a top view in the opposite direction. The connection fitting part for the drawer, as a front fixation unit FE, comprises a base sheet 1, a support plate 2, a rotatably supported tuck bar 3, and a gate plate 4. The base sheet 1 has angled side walls 1c, which are braced on the outside of the side wall of the drawer and creates sufficient free space between the base sheet 1 and the outside of the side wall of the drawer that the limitedly vertically adjustable support plate 2, the rotatable and displaceable tuck bar 3, and the limitedly vertically adjustable gate plate 4 on the support plate 2 can be accommodated in this free space.

(27) In FIGS. 7 and 8, in viewing directions corresponding to FIGS. 6 and 5, the individual parts of the facing fitting 5 and the connection fitting part for the drawer are shown in an exploded assembly position. In both FIGS. 7 and 8, the individual parts of the facing fitting 5 and of the connection fitting part for the drawer can be seen. The base sheet 1, on its underside and the two vertical sides, has angled side walls 1c, which create a free space on the back side of the base sheet 1. On the right-hand vertical side, the base sheet 1 has two elongated openings 1a, located one above the other, which stamped-out and outward-bent tabs 2a of the support plate 2 engage and in which the tabs are limitedly vertically adjustable. The base sheet 1 furthermore has an oval opening 1b, in which the vertical adjustment element 9 can be introduced and guided rotatably; the vertical adjustment element terminates in an eccentrically located guide bolt 9a, which is introduced into a bore 2i of the support plate 2. With this vertical adjustment element 9, the vertical position between the support plate 2 and the base sheet 1 can be varied by means of rotation. The support plate 2 has a curved, horizontal recess, in which a fork 2d is secured that diametrically surrounds a threaded end 10a of the lateral adjustment element 10 and is guided adjustably therein. In this way, by rotation of the lateral adjustment element 10, the lateral position between the base sheet 1 and the support plate 2 can be varied.

(28) A gate bolt 8 of the tuck bar 3 is introduced through a curved guide slot 4a of a gate plate 4 and a horizontal elongated opening 2f of the support plate 2 into the bearing bore 3c of the tuck bar 3. This tuck bar 3 is thus rotatable on the support plate 2 and is horizontally displaceable in the opening 2f. The tuck bar 3 has a guide slot 3d, which is formed by a lower part 3a and an upper part 3b of the tuck bar 3. The tuck bar 3 is rotatable and displaceable on the side of the support plate 2 oriented toward the base sheet 1. On the side of the support plate 2 facing away from the base sheet 1, a gate plate 4 is limitedly adjustable vertically. It is guided with angled ends 4b and 4c through openings 2e and 2g of the support plate 2, and by means of a crossbar the end 4c engages the opening 2g from behind and the angled end 4b engages the opening 2e from behind. In this way, the gate plate 4 is firmly held on the support plate 2. The gate plate 4 furthermore has an angled end 4d on the outside that receives a compression spring 7 with a guide pin 6. The compression spring 7 is braced on a shoulder 2k of the support plate 2. The support plate 2 has a horizontally extending guide slot 2b, which is bounded at the bottom by a part 2b and at the top by a part 2c of the support plate 2.

(29) Before the facing is attached to the drawer, the facing fitting 5 and the drawer are aligned with the connection fitting part in the manner shown in FIGS. 7a and 7b (in the drawings, only one connection point is ever shown).

(30) In this situation, the facing fitting 5 is aligned by the coupling bolt 11 with the insertion receptacle EFA of the guide slot 3d of the tuck bar 3. The horizontal slot 2b in the support plate 2 lengthens insertion receptacle EFA in the connection fitting part of the drawer toward the insertion side; the lower part 2h, dropping off at the front, of the support plate 2 further facilitates the insertion of the coupling bolt 11.

(31) After the facing has been placed against the connection fitting parts of the drawer, the coupling bolt 11 of the facing fitting 5 places itself on the lower part 3a of the tuck bar 3. Before that, the exact vertical and lateral positioning of the facing relative to the drawer has been performed by calibration and rotation of the vertical adjustment element 9 and of the lateral adjustment element 10, so that the process of connection between the facing fitting 5 and the connection fitting part on the outside of the side wall of the drawer can begin at the positions that can be seen in FIGS. 8a and 8b.

(32) As FIGS. 9a and 9b show, by further insertion of the facing fitting 5 into the connection fitting part on the outside of the side wall of the drawer, the tuck bar 3 is rotated about the gate bolt 8; the upper part 3b engages the coupling bolt 11 of the facing fitting 5 from behind. As can learned from FIG. 9a, until then the gate plate 4 remains in the lower vertical position; the compression spring 7 is compressed and tensed. The gate bolt 8 of the tuck bar 3 is still located in the upper region of the curved guide slot 4a of the gate plate 4 and still maintains the tensed position of the compression spring 7. The two facing fittings of the facing and drawer have almost reached their final position and thus are in the connection position.

(33) As FIGS. 10a and 10b show, upon the adjustment of the facing for contact with the face end of the drawer, the final position and the connection position of the two individual parts of the fastening fitting is reached. The gate bolt 8 of the tuck bar 3 has been thrust horizontally in the horizontal slot 2b of the support plate 2, without undertaking any further rotation. Furthermore, the gate bolt 8 of the tuck bar 3 has been displaced downward in the guide slot 4a of the gate plate 4, which leads to the relaxation of the compression spring 7, as can be seen in FIG. 10a. The upwardly adjusted gate plate 4 prevents the coupling bolt 11 of the facing fitting 5 from being pulled out of the slot 2b of the support plate 2 and thus also prevents a reversal and rotation backward of the tuck bar 3.

(34) If the facing is removed from the face end of the drawer, then on the accessible visible side of the connection fitting part of the drawer, a pressure downward is exerted, for instance by means of a screwdriver, on the part 4b guided by the support plate 2, as FIG. 11 shows.

(35) Then, as FIG. 12 shows, the compression spring 7 is tensed again, and the gate bolt 8 of the tuck bar 3 is pushed somewhat out of the horizontal slot 2b of the support plate 2. The gate bolt 8 of the tuck bar 3 is held in the lower position by the upper horizontal end of the guide slot 4a and thus by the gate plate 4. The compression spring 7 is tensed, and the gate plate 4 enables the continued removal of the facing from the drawer.

(36) As FIG. 13 shows, in the process the tuck bar 3 is rotated back into its insertion position and maintains that position when the facing fitting 5 is separated from the fitting part of the drawer, as FIG. 14 shows.

(37) It must also be mentioned that the construction of the left side wall SW of the drawer is the same; however, the front fixation unit FE is introduced laterally reversed into the side wall of the drawer, so that the insertion receptacle EFA is again facing toward the back side of the facing B, and the housing G of the front fixation unit FE has the recess A on the outside of the side wall SW, in order to gain access to the vertical adjustment element 9 and the lateral adjustment element 10.

(38) In particular, the side wall SWA comprises glass, metal, wood, stone, etc.

(39) The connecting part AD can be inserted, as is done with wood. However, it could also be glued to SWA or snapped on, or it could take the form of any other mechanically releasable or nonreleasable connection.

(40) The part AD can equally be integrated with the unit X in a releasable, glued, or nonreleasable manner. It could also be that no part AD is required; in that case, the connection in the unit X would already be a part of that unit.

(41) In other words, the part AD is not necessarily required, but can be required. In that case, the details of the receptacle would simply already exist in the unit X (for example, as a plate, bent over double, with corresponding detail).

(42) What is important overall is that the dresser drawer guide is separate and not necessarily connected to the side wall SWA and to the unit X and/or part AD.
