(39) The bearing members of the carriages 20, 21 are preferably external cylindrical bearing members or rolling bearing members, respectively, such as bearing rollers or bearing needles.

(40) The central rail 18 which is formed from an originally flat planar sheet metal is formed as a hollow section and across the length according to the longitudinal axis S has a materially integral connection, or a welded connection, or a narrow weld seam 29, respectively. The weld seam 29 that is preferably established by way of a continuous laser method on one side of the central rail 18 connects narrow, mutually abutting peripheries of a lower part-region and an upper part-region of the central rail 18.

(41) The hollow section shape of the central rail 18 in mechanical terms enables a highly stable, in particular, flexurally rigid and torsionally rigid, central rail 18.

(42) The central rail 18, according to the shaping thereof, is moreover configured so as to be compact, or space-saving, respectively, and material-saving.

(43) FIG. 5 shows the item of furniture 1 according to FIG. 1, without a left part-region, when seen from the front, from below, or in a lower view, having the drawer 3 deployed in the direction P1. An exemplary connection device 37 according to the present invention acts on the rail full pullout 7, which is designed as a full pullout 16 according to FIG. 4. The connection device 37 serves inter alia for the vertical or height adjustment, respectively, of the drawer 3 relative to the furniture cabinet unit 2.

(44) A corresponding connection device 37 according to the present invention acts on the rail full pullout 6 (not shown in FIG. 5) that is required for moving the drawer 3, the rail full pullout 6 being likewise designed so as to correspond to the full pullout 16 from FIG. 4. The connection device 37 is preferably composed from a plastics material or a light metal material. FIG. 6 shows only the fully contracted rail full pullout 6 from above, having the connection device 37 which is disposed in a functionally correct manner on the rail full pullout 6 and which is located in a minimum position, the latter being explained hereunder. The drawer 3, by way of an in each case lateral part of the lower side of the drawer base 14, is accordingly supported on the two rail full pullouts 6 and 7, or on the respective upper side 19a of the sliding element rail 19, respectively.

(45) The drawer 3 in the height position relative to the furniture cabinet unit 2 is thus adjustable on both sides. To this end, a person manually activates from below the two connection devices 37 that are present below the drawer 3, for example, when the drawer 3 is completely deployed according to FIGS. 1 and 5.

(46) The connection device 37 is screw-fitted below the drawer 3, or to a lower side of the drawer base 14 in the region of a front base corner region, respectively, for example, by way of screw-fitting means such as two screws 38 which engage through prepared openings in the connection device 37 and are screw-fitted to the lower side in the drawer base 14. A fastening of the connection device 37 to the rear side on the front element 12 is likewise possible.

(47) The connection device 37 comprises adjustment means 39, wherein the adjustment means 39 have latching means 40, an operating element 41, and a height adjustment element 42. The latching means 40 have a plurality of latching teeth 43 that are disposed in a row, and a latching member 44.

(48) The latching member 44, depending on the setting of the connection device 37, interacts with a portion of the row of latching teeth 43. The latching teeth 43 are disposed along a shell face 45 on a main component 46 of the connection device 37. The latching member 44 is connected to the operating element 41 and by way of the latching teeth 43 projects from the operating element 41 in the direction of the shell face 45. The latching member 44 in the case of the embodiment illustrated is configured so as to be integral to the operating element 41, or so as to be integral on the latter, respectively.

(49) The main component 46 is preferably a narrow plastics material part which is provided with webs and cavities and is plate-shaped in the main design, for example, and which preferably comprises hollow portions, for example, or chamber portions that are separated from the peripheral and internal webs. The planar narrow ends on the upper side of the webs of the main component 46 define a plane of an upper side 37a of the connection device 37 (cf. FIG. 7), the connection device 37 bearing on the planar drawer base lower side by way of the upper side 37a. A rotary mounting 53 of an actuator component 54, or of the height adjustment element 42, respectively, is also designed on the upper side 37a.

(50) The height adjustment element 42 has an upper side having upper-side planar end portions, the upper-side end portions being aligned with the upper-side ends of the webs of the main component 46, or lying in the plane of the upper side 37a, respectively.

(51) This means that the upper-side ends of the webs of the main component 46 and of the height adjustment element 42 in the screw-fitted state of the connection device 37 bear in a planar manner on the lower side of the drawer base 14.

(52) The operating element 41, the latching member 44, and the height adjustment element 42 are preferably formed so as to be integral, or form the separate actuator part 54 which is preferably plug-fittable to the main component 46 in a releasable manner. The actuator part 54 in a central portion that can be seen in FIG. 7 has an opening, for example, a split pin-type rotary bearing portion on the main component 46 reaching through the opening. The actuator part 54 is largely obscured in the figures; the actuator part 54 together with the entire height-adjustment element 42 being visible only in FIGS. 7 and 9.

(53) The operating element 41 by way of an elastic member 41a (cf. FIG. 14) such as, for example, spring means such as a spring arm, is received so as to be movable in an elastic or sprung manner, respectively, in the directions P6 and P7 on the central portion of the actuator part 54. The operating element 41 by way of the spring means is pretensioned in a direction P6 such that the latching member 44 makes its way in a self-acting manner to a latching action with one of the latching teeth 43 and remains there as long as no external or manual action, respectively, is correspondingly exerted on the operating element 41. The latching action is self-locking by way of the spring force of the spring means, or of the elastically pretensioned member 41a, respectively. The operating element 41 by way of the elastic member 41a is offset in relation to the height adjustment element 42 by the spacing V in the axial direction of the rotation axis S.

(54) The height adjustment element 42 on the main component 46 is pivotable or rotatable, respectively, in a reciprocating manner about a pivot axis or rotation axis S, respectively, in a manner limited by the detents 47 and 48, this being performed manually by an operator acting externally on the operating element 41. The rotation axis S is perpendicular to the plane of the upper side 37a.

(55) The height adjustment element 42 that is attached to the central portion of the actuator part 54, or is present so as to be integral on the latter, respectively, is configured in the manner of a disk, preferably in the manner of an annular disk according to a divided ring. The divided ring according to the exemplary embodiment of the height adjustment element 42 illustrated has, for example, a radial width of approximately 10 millimeters at an external circumference of approximately 35 millimeters. The circumferential extent a of the divided ring, or of the height adjustment element 42 in relation to the rotation axis S is approx. 80 to 100 degrees, preferably approximately 90 degrees (cf. FIG. 9).

(56) The height adjustment element 42 at a front free end 42a has a minimum thickness of, for example, zero to 0.1 millimeters, and at the other non-free end 42b thereof has a maximum thickness which is, for example, approximately 3 to 5, preferably approximately 4 millimeters.

(57) The height adjustment element 42 in relation to the assembled use state has an upper side 42c, or on the upper side is preferably provided with a planar bearing edge, or a bearing edge that runs perpendicularly to the rotation axis S, respectively, and on the lower side is provided with a profile that is oblique in relation to the rotation axis S. The gradient of the thickness of the height adjustment element 42 is determined by an angle which is preferably between approximately 5 and 9 degrees, preferably approximately 7 degrees (cf. FIG. 13). The variation of the thickness of the height adjustment element 42 is preferably performed so as to be stepless and/or preferably uniform. A wedge-type or ramp-type shape, respectively, of the height adjustment element 42 is thus provided.

(58) Proceeding from the minimum position of the connection device 37 according to FIG. 8 or FIG. 10, respectively, according to which the latching member 44 is latched in a self-locking manner on the latching teeth 43, and in the actuation direction P5 bears in a blocking manner (cf. FIG. 9) on the detent 47, the operating element 41 by way of manual action thereon is pushed outward in the direction P7. The latching member 44 herein exits the latching action and can then be rotated or adjusted, respectively, in the direction P4 about the rotation axis S, the height adjustment element 42 thus also being rotated in the direction P4. This adjustment movement can be performed at maximum to the terminal or maximum position, respectively, of the connection device 37 according to FIG. 9, the latching member 44 in the terminal or maximum position, respectively, mechanically bearing on the detent 48 and being blocked by the latter. Depending on the adjustment path travelled by the operating element 41, the height adjustment element 42 is rotated outward by a corresponding distance in the direction P4. The height adjustment element 42 herein, by way of the free end 42a thereof, pushes or forces, respectively, itself ahead between the lower side of the drawer base 14 and the upper side 19a of the sliding element rail 19. The height adjustment of the drawer 3 relative to the guide rail 19 and thus to the furniture cabinet unit 2 takes place herein, this being highlighted by FIGS. 13 and 14.

(59) FIGS. 13 and 14 show the connection device 37 and the drawer base 14 only in fragments and in schematic contours and indicated by dashed lines.

(60) FIG. 13 shows the minimum position of the connection device 37 according to FIG. 8, wherein a minute spacing a0 of zero millimeters is established between the lower side of the drawer base 14 and the upper side 19a of the sliding element rail 19. The drawer base 14 is accordingly supported directly on the sliding element rail 19. The height adjustment element 42 on the connection device 37 is pivoted completely back in the direction P5 and therefore does not engage between the lower side of the drawer base 14 and the upper side 19a of the sliding element rail 19. In the vertical direction, or in the height direction H, respectively, (cf. FIG. 14), the drawer 3 according to FIG. 13 is located at a lowermost height position on the furniture cabinet unit 2, or on the item of furniture 1, respectively.

(61) By adjusting the height adjustment element 42 by pressing the operating element 41 in the direction P7 and sliding the operating element 41 in the direction P4, wherein the latching member 44 is released from the latching action with the latching teeth 43, the height adjustment element 42 is rotated in the direction P4 and by way of the portions thereof in which the thickness increases from the free end 42a to the end 42b slides between the lower side of the drawer base 14 and the upper side 19a of the sliding element rail 19. A maximum spacing al between the lower side of the drawer base 14 and the upper side 19a of the sliding element rail 19 of, for example, 4 millimeters is reached in the maximum position, when the latching member 44 bears on the detent 48. In the vertical direction, or in the height direction H, respectively, the drawer 3 is located in an uppermost height position on the furniture cabinet unit 2, or on the item of furniture 1.

(62) A corresponding intermediate height position becomes capable of being set in all of the potential rotated intermediate positions of the height adjustment element 42, having a spacing a between the minimum spacing a0 and the maximum spacing al between the lower side of the drawer base 14 and the upper side 19a of the sliding element rail 19.

(63) The securing of the latching member 44 in an actuated position by way of the latching action of the latching member 44 on the respective portion along the row of the latching teeth 43 is implemented in a self-acting manner by releasing the compressive action on the operating element 41 on account of the sprung pretension on the latching member 44 in the direction P6 by way of the elastic member 41a, or the spring arm, respectively, on which the operating element 41 is received in a sprung and resettable deflectable manner.

(64) The latching teeth 43 are preferably disposed along the shell face 45, or a conical face, respectively, or a conical shell face, respectively. The associated part-cone 50 that is shaped on the main component 46 is designed, for example, as a truncated cone that in relation to the cone axis is circumferentially delimited to approximately 90 degrees, the latching teeth 43 on the shell face 45 of the truncated cone being present so as to be aligned in a mutually parallel manner. The cone axis of the associated truncated cone preferably coincides with the rotation axis S. The conical shell face of the part-truncated-cone contracts in the direction toward the upper side 37 of the connection device 37. An intensity of the latching effect of the latching member 44 with the latching teeth 43 can be influenced by way of the length of the latching teeth 43, for example.

(65) The latching member 44 in the minimum position establishes a latching connection with a first latching tooth which is designed as the retaining tooth 49 and in the direction P4 is positioned at the first position in the row of the latching teeth 43. The detent 47 is formed so as to neighbor the retaining tooth 49 in the direction P5. The retaining tooth 49 has tooth flanks which converge toward the tip of the retaining tooth 49 and which in relation to a direction radial to the rotation axis S preferably have a smaller angle than the flanks of the respective remaining latching teeth 43. A resistance to unlatching the latching member 44 from the latching action on the retaining tooth 49 is thus comparatively increased as compared to a resistance for unlatching the latching member 44 from the latching action with one of the remaining teeth 43 which are preferably mutually the same or identical, respectively, having flanks of the respective latching teeth 43 that are preferably shaped in a mutually identical manner. The more intense latching effect of the latching member 44 on the retaining tooth 49 is advantageous, in particular, to the minimal or transportation position, respectively, of the connection device 37 that is illustrated in FIG. 10.

(66) Each of the latching teeth 43 has two opposite latching flanks, or latching faces 51 and 52, respectively (cf. FIG. 12a), wherein the latching faces 51 and 52 enclose a latching angle , wherein the latching angles of all of the latching teeth 43 are preferably almost identical, for example, being approximately 40 to 60 degrees, in the exemplary embodiment illustrated being preferably approximately 50 degrees. The latching face 51 in relation to the radial R, which runs through the rotation axis S and the tip of a latching tooth 43, is angled at the angle 1, and the latching face 52 is angled at the angle 2 which is larger in relation to the angle 1. The angles 1 and 2 complement one another to form the latching angle .
