DETAILED DESCRIPTION OF THE INVENTION

(8) An item of furniture 50 according to the present invention, having a box-shaped basic furniture structure 51 and a drawer 53 which by way of guide means 52 is movably guided, is illustrated in FIG. 1. The drawer 53 comprises a drawer base 54, a drawer front 55, two mutually opposite side walls 56, and a rear drawer wall 57. Two guide means 52 with identical action for guiding the drawer 53 are present in each case between each side wall 56 of the drawer 53 and an associated basic-structure side wall 59. A device 58 according to the present invention (illustrated with dashed lines), for moving or ejecting, respectively, the furniture part which is configured as a drawer 53 in the opening direction M1 is disposed on a lower side of the drawer base 54.

(9) FIG. 2 shows the exploded illustration of the device 58 which is configured as an ejector unit 1 for the drawer 53.

(10) The ejector unit 1 serves for the force-assisted ejection of the drawer 53 across a first part-distance of the opening movement of the drawer 53 in relation to the basic furniture structure 51, from a closed position in the opening direction M1 of the drawer 53.

(11) The drawer 53 by way of the guide means 52, for example, two identical part pullouts or full pullouts, is mounted on the basic furniture structure 51 so as to be displaceable in the directions M1 and M2. Alternatively, the ejector unit 1 may be disposed on the basic furniture structure 51 or on the guide means 52 of the item of furniture 50.

(12) The ejector unit 1 comprises inter alia a base plate 2, a force accumulator 3, a coupling installation 4, an ejector 5, an activation element which is configured as an activator 6, and a locking member 7.

(13) A housing of the ejector unit 1 comprises the base plate 2 and a cover component 9 which is visible in FIG. 9. The ejector unit 1 may be disposed on the lower side of the drawer base 54 and/or on the guide means 52 by way of the housing or by way of the cover component 9 and/or the base plate 2, respectively.

(14) Retaining portions, guide contours, stop members, and/or receptacle portions for linking the individual components of the ejector unit 1 are configured on the base plate 2. The base plate 2 is designed substantially as a rectangular, elongate or strip-shaped component, having a comparatively minor height h of approx. 5 to 15 millimeters, for example. The base plate 2 furthermore has a width b of approx. 4 to 10 centimeters, and a length g.

(15) According to the exemplary embodiment shown, the force accumulator 3 comprises two identical coil springs 10, 11 which configure a spring pack and which are disposed in parallel. At a first end 12 of the force accumulator 3, the coil springs 10, 11 are disposed on an adjustable fixed mounting 13. The fixed mounting 13 comprises a movable mounting part 14 on which the coil springs 10, 11 are received in a releasable yet fixed manner, and a set part 15 having an operating portion 16 by way of which a user may adjust from the outside a position of the end 12 of the force accumulator 3 in a modifiable and positionally fixed manner. On account thereof, an effect of force of the force accumulator 3 on a drawer 53 may advantageously be pre-adjusted in the case of the opening procedure of the drawer 53.

(16) The associated ends of the coil springs 10, 11 are fastened to a slide-type motion element 18 at a second end 17 of the force accumulator 3. The slide-type motion element 18 by way of an associated guide contour 19 is linearly guided on the base plate 2 so as to be movable in a movement direction P1 and in an opposite movement direction P2.

(17) The movement directions P1 and P2 of the motion element 18 (cf. FIGS. 2 and 3) run parallel with the opening direction M1 of the drawer 53 and with a closing direction M2 which is counter thereto.

(18) If and when the ejector unit 1 is disposed in a positionally fixed manner on the basic furniture structure 51 and/or on a stationary part of the guide means 52, the opening direction of the drawer 53 corresponds to the direction P1, and the closing direction of the drawer 53 corresponds to the direction P2.

(19) Herebelow, an assembled state of the ejector unit 1 on the drawer base 54 is assumed.

(20) FIGS. 3, 7 and 8 show the ejector unit 1 in a tensioned state of the force accumulator 3, in which the coil springs 10, 11 are elongated or are tensioned so as to be under a tensile load, respectively; herein, the motion element 18 in relation to a retracted position in the direction P2 is offset on the base plate 2 in the direction P1 and is retained in a tensioned position.

(21) FIGS. 5 and 6 show the ejector unit 1 in a discharged basic state of the force accumulator 3, in which the coil springs 10, 11 are furthermore tensioned under a tensile load but to a lesser degree, having a length L1.

(22) In the tensioned state of the force accumulator 3 the coil springs 10, 11 have a length L2 which is greater than L1.

(23) A retaining element 32 having the stop element 26 is present on the motion element 18.

(24) By way of the coupling installation 4, the force accumulator 3 or the motion element 18, respectively, is operationally connected to the ejector 5, preferably exclusively in the case of the closing procedure of the drawer 53. In particular, the ejector 5 is movable to and fro exclusively in a linear manner, or so as to be parallel with the movement direction of the motion element 18, respectively, in the directions P1 and P2. To this end, a linear guide 20 which is adapted to guide portions, for example, on one side of the ejector 5 is configured on the base plate 2.

(25) An opening procedure of the drawer 53, caused by the ejector unit 1, takes place exclusively by way of a direct operational connection of the force accumulator 3 to the ejector 5, by way of the motion element 18 which moves in the direction P2. To this end, a stop element 26 which is advantageously designed so as to be elastic and thus prevents or at least dampens any sound which is disturbing to a user when the motion element 18 impacts the ejector 5 in the opening procedure of the drawer 53 is configured on the motion element 18 (FIGS. 3, 4 and 5).

(26) A front-gap adjustment assembly 8 which is configured on the ejector 5 comprises a housing 45 and a set screw 22 having a contact portion 21. The set screw 22 has an external thread which interacts with an internal thread on the housing 45. Depending on the rotation direction, a position of the contact portion 21 of the set screw 22 is adjustable in the direction P1 or P2 by manual rotation of an operating portion 46 of the set screw 22 by a user. In particular, the set screw 22 is configured so as to be self-locking in relation to the housing 45. A measure of a front gap between the drawer front 55 of the drawer 53, which is closed on the basic furniture structure 51, and end sides of the basic furniture structure 51 is capable of being predefined by way of the predefined position of the set screw 22.

(27) The contact portion 21 of the set screw 22 in the tensioned or charged state, respectively, of the force accumulator 3 bears on an entrainment element 23 which in respective operational states forms a stop for the contact portion 21. The entrainment element 23 which in FIGS. 3 to 8 is merely indicated by dashed lines may be present on a fixed rail of the guide means 52, for example, or be attached to the basic furniture structure 51 when the ejector unit 1 is disposed on the drawer 53.

(28) However, if and when the ejector unit 1 is disposed on the basic furniture structure 51 or on a positionally fixed part of the guide means 52 of the item of furniture 50, the entrainment element 23 may be present on the drawer 53 and thus be movable in relation to the basic furniture structure 51.

(29) If and when, proceeding from the basic position of the ejector unit 1 according to FIG. 3, a locking feature is cancelled on the ejector unit 1, as is shown in FIG. 4 and will be explained in more detail below, the tensioned or charged force accumulator 3, respectively, pulls the motion element 18 in the direction P2, the latter by way of the stop element 26 urging or sliding, respectively, the ejector 5 in relation to the base plate 2 in the direction P2.

(30) As soon as the ejector 5 on the base plate 2 moves in the direction P2, a latch component 24 of the ejector unit 1, which is pivotably mounted on the ejector 5, is put from an inwardly pivoted position according to FIG. 4, in which the latch component 24 in relation to an external periphery of the base plate 2 is completely retracted, to an outwardly pivoted position in which the latch component 24 by way of a cam partially projects beyond the external periphery of the base plate 2 (FIG. 5), this being implemented by way of a loop-shaped closed guide track 25 in the base plate 2 and by way of a guide pin 24a, engaging in the guide track 25, on the latch component 24.

(31) In order for the latch component 24 to be illustrated, the outline thereof which is obscured by other components, in particular, by the ejector 5, in FIGS. 3 to 8 is indicated with dashed lines.

(32) In the basic state which is illustrated in FIG. 5, the force accumulator 3 is located in a terminal position of the discharged state, wherein the force accumulator 3 is unable to move the ejector 5 any farther in the direction P2.

(33) By virtue of the kinetic energy of the drawer 53, caused by the preceding ejection movement and/or by manually moving the drawer 53 farther in the opening direction M1 by a user, the ejector 5 is subsequently displaced in relation to the base plate 2 in the direction P2. This is possible because the latch component 24 which has been outwardly pivoted so as to project from the ejector 5 bears on the entrainment element 23, the ejector 5 in the further course of the movement of the drawer thus reaching the terminal position thereof which is displaced to a maximum in the direction P2 on the base plate 2. By reaching the terminal position on the ejector 5, the latch component 24 is again completely pivoted inward, this being predefined by the interaction between the guide track 25 and the guide pin 24a on the latch component 24 being engaged therein.

(34) If and when the drawer 53 following a discharging procedure of the force accumulator 3 is moved farther in the opening direction M1, the ejector unit 1 separates from the entrainment element 23, cancelling contact between the entrainment element 23 and the contact portion 21 of the set screw 22 (FIG. 6).

(35) From the terminal position described above, which the ejector assumes only briefly, the ejector 5 by spring elements 33 on the base plate 2 is urged by a few millimeters in the direction P1, for example. In relation to the coil springs 10, 11 of the force accumulator 3, the spring elements 33 have a comparatively minor force. By way of the movement of the ejector 5 in the direction P1 by way of the force of the spring elements 33, a bearing portion 29 of the latch component 24 in a standby position of the ejector 5 is put in direct clearance-free contact with a mounting pin 31 of a tension lever 30 of the coupling installation 4 (FIG. 6). The mounting pin 31 is disposed on a first end of the tension lever 30 and may move freely along a, for example, linear, guide track 27 and/or a linear guide 63 which is configured on the ejector 5 for so long, and, in particular, within an opening procedure of the drawer 53, until the latch component 24 holds the mounting pin 31 and/or the tension lever 30 in direct, clearance-free contact with the ejector 5.

(36) The standby position of the ejector 5 which is shown in FIG. 6 at the same time is a starting position of the ejector 5 for a charging procedure of the force accumulator 3 by way of the coupling installation 4.

(37) Besides the tension lever 30, the coupling installation 4 comprises a guide lever 34 and a connection element 35. By way of a mounting pin 36, the tension lever 30 on a second end is articulated on the guide lever 34. The connection element 35, on a second end, by way of a mounting pin 37 which is spaced apart from the mounting pin 36, is likewise articulated on the guide lever 34, and on the first end thereof, the connection element 35 by way of a further mounting pin 38 is articulated on the motion element 18. The guide lever 34 at a first end by way of a mounting pin 39 is disposed so as to be movable, in particular, pivotable, on the base plate 2. The mounting pin 39 is preferably received both on the base plate 2 as well as on the cover component 9.

(38) A longitudinal axis A3 of the tension lever 30, which runs through the mounting pins 31, 36 of the tension lever 30, in relation to a first longitudinal axis A2 of the guide lever 34, which runs through the mounting pins 36, 39, has an angle .

(39) A longitudinal axis A3 of the connection element 35, which runs through the mounting pins 37, 38 of the connection element 35, in relation to a second longitudinal axis A4 of the guide lever 34, which runs through the mounting pins 37, 39, has an angle .

(40) The guide lever 34 of the coupling installation 4, on a second end, comprises a lever attachment 40. A locking element 41 and a stop element 42 are configured on the lever attachment 40.

(41) The terminal position of the discharged state of the force accumulator 3 (FIG. 5) is predefined by a stop of the stop element 42 of the guide lever 34 on a wall portion 47 on a step-type wall 48 of the base plate 2. The wall portion 47 is formed from an annular portion of a damping element, for example. If and when the stop element 42 of the guide lever 34 following a discharging procedure of the force accumulator 3 bears on the wall portion 47, by virtue of a remaining bias of the coil springs 10, 11 a tensile force in the direction P2 is transmitted from the motion element 18 by way of the connection element 35 to the guide lever 34. By virtue of the rigid embodiment of the coupling installation 4, or by virtue of the impact of the stop element 42 on the wall portion 47, respectively, the motion element 18 is prevented from moving farther in the direction P2, wherein the force accumulator 3 by way of the motion element 18 is held free of clearance in the terminal position of the discharged state.

(42) In particular, the stop element 42 and/or the wall portion 47 may be designed so as to be elastic or damping, respectively, thus reducing or preventing an impact noise.

(43) When tensioning the force accumulator 3, the guide lever 34 by virtue of the design thereof may transmit a force from the tension lever 30 to the connection element 35 at a geared up ratio.

(44) The gear ratio is formed, on the one hand, by the ratio of the spacing of the mounting pins 39 and 36 in relation to the spacing of the mounting pins 39 and 37 on the guide lever 34 and, on the other hand, by the combined mutual circular and linear movement of the tension lever 30 and/or of the connection element 35 during the charging procedure of the force accumulator 4.

(45) The elements of the coupling installation 4, by virtue of the arrangement of the former on the ejector unit 1, may move as follows:

(46) The mounting pin 31 and thus the first end of the tension lever 30, by virtue of the mounting thereof in the guide track 27, may move exclusively parallel with a movement direction of the ejector 5, in particular, parallel with a movement direction of the movable furniture part 53.

(47) The mounting pin 38 and thus the first end of the connection element 35, by virtue of the mounting thereof on the slide-type motion element 18 and thus advantageously in the guide contour 19, may move exclusively parallel with a movement direction of the motion element 18 or of the ejector 5, respectively, in particular, parallel with the movement direction of the movable furniture part 53.

(48) The mounting pin 36 and thus the second end of the tension lever 30, by virtue of the mounting thereof at the second end of the guide lever 34, may move exclusively in a circular path about a rotation center of the mounting pin 39 of the guide lever 34.

(49) The mounting pin 37 of the connection element 35 and thus the second end of the connection element 35, by virtue of the mounting thereof in a central region of the guide lever 34, may move exclusively in a circular path about a rotation center of the mounting pin 39 of the guide lever 34.

(50) By virtue of the above-mentioned design, the coupling installation 4 may transmit at a geared up ratio a force for tensioning the force accumulator 3 from the ejector 5 by way of the tension lever 30 and of the guide lever 34 to the connection element 35 and thus to the force accumulator 3, and, in particular, transmit the force which is exerted by the ejector 5 in a geared down ratio to the force accumulator 3. This means that a user when charging the force accumulator 3 has to apply less force to the ejector 5 than the user would have to apply when wishing to charge the force accumulator 3 without gearing down, or when directly pulling the end 17 of the force accumulator 3 in the direction P1, respectively.

(51) The beginning and the end of the charging procedure of the force accumulator 3 or of the coil springs 10, 11, respectively, are visualized in FIGS. 6 and 7.

(52) Tensioning of the force accumulator 3 is performed by a movement of the drawer 53 in the case of closing, or on a part-distance of the closing movement of the drawer 53. The starting position of the ejector unit 1, in which the latter is prepared for tensioning of the force accumulator 3 and expects a closing procedure of the drawer, is shown in FIG. 6.

(53) If and when the drawer 53 is closed, for example, from the outside by a user, the ejector unit 1 moves in the direction M2 toward the entrainment element 23. The charging procedure of the force accumulator 3 begins as the contact portion 21 of the set screw 22 of the ejector 5 impacts on the entrainment element 23. The ejector 5, by impacting on the entrainment element 23, is moved in the direction P1, for example, by virtue of the inertia of the drawer 53 in relation to the base plate 2.

(54) By way of the coupling of the ejector 5 to the force accumulator 3 by way of the coupling installation 4, the motion element 18 of the force accumulator 3 is likewise displaced in relation to the base plate 2 in the direction P1, and the second end 17 of the coil springs 10, 11 is displaced in the direction P1, the coil springs 10, 11 thus being elongated.

(55) At the end of the tensioning procedure of the force accumulator 3, the ejector 5 is located in a terminal charging position, as is shown in FIG. 7. In a tensioned state of the force accumulator 3, the ejector unit 1 is located in a locked state.

(56) In the locked state, a locking state is determined by the locking element 41 of the coupling installation 4 and by the locking member 7 which is configured as a flap, wherein a discharging movement of the coupling installation 4 is blocked by the locking member 7.

(57) Tensioning of the force accumulator 3 is fully completed prior to an automatic retracting feature for the force-assisted retraction of the drawer 53 to the fully closed position on the basic furniture structure 51 becoming effective, for example. The automatic retracting feature is not part of the ejector unit 1, and is integrated in the guide means 52 or in the part pullouts or full pullouts, respectively, for example.

(58) After the force accumulator 3 has been tensioned, the ejector 5 by virtue of bearing on the entrainment element 23 is moved farther in relation to the base plate 2 by way of the further closing movement of the drawer 53. Herein, the operational connection between the latch component 24 of the ejector 5 and the mounting pin 31 of the tension lever 30 is cancelled. This is performed by an interaction between the guide track 25 and the guide pin 24a on the latch component 24, wherein the latch component 24 by the guiding of the guide pin 24a in the guide track 25 is pivoted away from the mounting pin 31 (FIG. 8). In this state, the ejector 5 is uncoupled from the coupling installation 4 and is displaceable so far in the direction P1, in particular, by an automatic retracting feature, until the drawer 53 is fully closed on the basic furniture structure 51, and the ejector 5 bears on the activator 6 in the basic position according to FIG. 3.

(59) In the basic position of the ejector unit 1 according to FIG. 3, it is possible for a user to pull the drawer 53 in the opening direction M1 without an ejector function or without first manually cancelling the locking state, respectively. Herein, the force accumulator 3 of the ejector unit 1 remains non-actuated or charged, respectively.

(60) In order for the drawer 53 by way of the ejector unit 1 to be expelled from the position in which the drawer 53 is completely retracted or closed, respectively, on the basic furniture structure 51, a user has to act on the drawer while pushing from the outside in the direction M2. To this end, the ejector unit 1 has a so-called touch-latch function which knows a locked state which is unlockable in that the retracted drawer 53 which is closed on the basic furniture structure 51 is moved in the closing direction M2. This closing movement, or inward pushing of the drawer 53 in the direction M2, respectively, is performed until a stop position corresponding to a front gap which in the closed state of the drawer 53, is predefined, in particular, by way of a spacing between an internal side of the drawer front 55 and a forward end side or the side walls 56 of the basic furniture structure 51, respectively, is reached. The front gap is typically a few millimeters, for example, approx. 1 to 10 millimeters.

(61) Accordingly, unlocking of the ejector unit 1 is adapted in such a manner that a closing movement of the drawer 53 in the direction M2 of a few millimeters, or at maximum by the value of the front gap, respectively, is sufficient for unlocking and thus the force-assisted ejection of the drawer 53 to be reliably predefined.

(62) Proceeding from the basic position according to FIG. 3, the ejector unit 1 together with the drawer 53 is moved in the direction M2. Since the stop screw 22 bears on the entrainment element 23, the ejector 5 is moved in relation to the base plate 2 in the direction P1, a contact portion 44 on the ejector 5 thus pressing against the activator 6, accordingly pushing the latter in the direction P1. The activator 6 is present on the base plate 2 so as to be linearly displaceable in a limited manner, typically by a few millimeters or by less than the dimension of the front gap, respectively, in the directions P1 and P2.

(63) The activator 6 is preferably directly coupled to the locking member 7 which is designed as a flap 43 in such a manner that the linear activation movement of the activator 6 in the direction P1 sets the flap 43 in rotary motion about a pivot axis D. The flap 43 by the rotating movement is released from a locked position into which the flap 43 is urged by a spring member which is configured as a leaf spring 49. In the locked state of the ejector unit 1, the flap 43 which is located in the locking position blocks the guide lever 34 or the lever attachment 40, respectively, in such a manner that the force accumulator 3 remains in the charged state thereof.

(64) Blocking of the guide lever 34 is cancelled by the rotating movement of the flap 43. The locking element 41 on the lever attachment 40, which is biased by a leg spring 60, hereby preferably pivots out.

(65) The locking element 41, which projects from the lever attachment 40, moves conjointly with the pivoting procedure of the guide lever 34 below the flap 43, past the latter, and continues without interruption the rotating movement of the flap 43, initiated by the activator 6, about the pivot axis D. On account thereof, a rotation angle of the flap 43 out of the locking position is advantageously enlarged. The ejector unit 1 is reliably unlocked by the movement of the lever attachment 40 below and past the flap 43 and continued by the outwardly pivoting locking element 41. To this end, an advantageously comparatively very minor linear activation movement of the activator 6 in the direction P1 is required. Subsequently, the flap 43 by the leaf spring 49 is urged back into the locking position of the former.

(66) The locking element 41 which is present so as to be outwardly pivoted on the lever attachment 40 is again brought to bear on a front edge of the flap 43 when the force accumulator 3 is tensioned. Herein, the locking element 41 yields counter to the spring force of the leg spring 60, such that the locking element 41 is retracted so far on a periphery of the lever attachment 40 that the guide lever 34 by way of the lever attachment 40 can pivot past the flap 43.

(67) Behind the flap 43, the locking element 41 is outwardly pivoted again by the spring force of the leg spring 60. Following the tensioning procedure, the guide lever 34 by way of the projecting locking element 41 is pushed against the flap 43 which is held by the leaf spring 49 so as to lock, the force accumulator 3 thus being in the locked state.

(68) The rotating movement of the flap 43 of the ejector unit 1, or of the device 58, respectively, is transmitted by a synchronizer bar 61 which is disposed so as to be rotationally fixed on the flap 43 to a second device 62 which is advantageously of identical action and which is disposed on the drawer 53.

(69) The synchronizer bar 61 advantageously connects the locking member 7 to a second locking member which is present on the second device 62. The two locking members are thus directly and/or synchronously coupled in terms of motion. This represents a synchronizing principle which is contrarian to a connection between activator elements of two ejector units on one furniture part.

(70) FIG. 10 in a perspective manner in a view from below shows the cover component 9 of FIG. 9, which by plug-fitting is connectable to the base plate 2. The cover component 9 is designed as a sheet-metal fastening panel 64 having a sheet-metal area portion 70 and peripheral shapings which are configured in a predefined manner.

(71) FIGS. 11 and 12 show further cover components 9 which match the identical base plate 2 of the ejector unit 1 and which are designed in an alternative manner to the sheet-metal fastening panel 64 as a sheet-metal fastening panel 65 and a sheet-metal fastening panel 66.

(72) The sheet-metal fastening panel 64 serves as a part-housing, or for covering the ejector unit 1 on a main side of the ejector unit 1, respectively. With the aid of the sheet-metal fastening panel 64, the ejector unit 1 on the guide means 52 and/or the drawer 53. Depending on the attachment point of the ejector unit 1 on the item of furniture 50, and, in particular, depending on the guide means 52 present, one of the sheet-metal fastening panels 64, 65, or 66, which is in each case configured so as to be adapted in a matching manner is used.

(73) Each of the sheet-metal fastening panels 64, 65, and 66 has connection means which comprise portions which are designed so as to be prepared for plug-fitting on or onto the base plate 2, respectively, and which differ from one sheet-metal fastening panel to another, or which each are dissimilar to another, respectively. Preferably, the portions are designed in peripheral regions of the respective sheet-metal fastening panel 64, 65, or 66. Accordingly, a plurality of prepared portions such as, for example, six spring lugs 67 for connecting to a cover component 9, or for interacting with associated matching connection means on the cover component 9, are designed on the base plate 2. The spring lugs 67 which here are bent back in a hook shape, for example, may compress somewhat elastically when the cover component 9 is plug-fitted onto the base plate 2. In the case of the completely assembled ejector unit 1, each spring lug 67 is snap-fitted to an associated window-type clearance 68 on the cover component 9, wherein the base plate 2 and the cover component 9 are capable of being latched to a plurality of points so as to correspond to the number of spring lugs 67, the number presently being six.

(74) The sheet-metal fastening panels 64, 65, and 66 each have the clearances 68 on the conforming points. Each of the sheet-metal fastening panels 64, 65, and 66 is thus connectable to the base plate 2 in an identical manner.

(75) Attaching the ejector unit 1 which, as has been described above, is assembled by plug-fitting the base plate 2 and one of the sheet-metal fastening panels 64, 65, and 66, to a furniture part and/or to the guide means 52 is establishable by way of plug-fitting, screw, latching, adhesive, and/or other types of connections.

(76) A common feature of the sheet-metal fastening panels 64, 65, and 66, are screw bores 69 for screw means (not illustrated) to engage therethrough for screw-fitting to the lower side on the drawer base 54, for example.

(77) The screw bores 69 are present on a first longitudinal side of the sheet-metal fastening panels 64, 65, and 66, on a lug 71 which by way of two rectangular bent-back features on the sheet-metal area portion 70 projects laterally in a parallel manner offset in relation to the sheet-metal area portion 70.

(78) A further lug 72 having a screw bore 73 is configured on the sheet-metal fastening panel 66 on the plane of the sheet-metal area portion 70.

(79) For further integration of the ejector unit 1, which is disposed on the lower side on the drawer base 54, on the guide means 52 or on a side frame of the nearest side wall 65, the connection means on the cover component 9, here at the sheet-metal fastening panels 65 and 66, comprise a web 74. The web 74 across the substantial length of the sheet-metal fastening panels 65 and 66 is designed having two mutually spaced apart and laterally projecting tongues 75. The web 74 on that longitudinal side of the sheet-metal fastening panels 65 and 66 that is opposite the lug 71 is present in a manner so as to be offset to and parallel with the sheet-metal area portion 70 by bent-back features. The tongues 75 may engage in a clamping manner, for example, in corresponding matching clearances on the guide means of a basic-structure rail, for example, and/or on the side wall of the drawer 53.

(80) Moreover, two mutually spaced apart and projecting tongues 76 are configured on the sheet-metal fastening panel 66 on the associated longitudinal periphery of the sheet-metal area portion 70.

(81) Furthermore, screw bores 77 are provided in the web 74.

(82) On the sheet-metal fastening panel 64 which has no web 74, the connection means have comparatively narrow hook-type lugs 78 and 79.

(83) The sheet-metal fastening panel 65 is configured for being inserted in a sunken manner into a depressed routed-out feature on the lower side on the drawer base 54. Therefore, the web 74, in a manner corresponding to the depth of the routed-out feature, is further set back in relation to the sheet-metal area portion 70. On account thereof, the tongues 75 on the plane of the lower side of the drawer base are configured for engaging in associated regions.

(84) With the exception of the web 74, the ejector unit 1 is then capable of being completely sunk into the drawer base 54, for example.

(85) The integration of the ejector unit 1 by means of the tongues 75, 76 and of the lugs 78, 79 is preferably performed without tools.
