In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the fastening device, panel, frame, panel support, adapter, connecting elements, wedge slide, retaining lug, selected in the respective figures. footbridge and the like. These terms are not to be construed in a limiting sense, ie, by different work positions or the mirror-symmetrical design or the like, these references can change.

In the figures 1 and 2 the reference numeral 1 designates a drawer as a whole. The drawer 1 has two side frames 4, a rear wall 3 and a panel 2 fixed to the side frames 4.

The panel 2 is fixed to the side frames 4 with the aid of a fastening device in such a way that the panel 2 is height-adjustable relative to the side frames 4 in a Z direction and also laterally adjustable in an X direction.

For this purpose, cutouts 41, 42 are provided in the outer wall of the side frame 4 on the side frames 4 immediately behind the panel 2 covering the side frames 4 to the front, through which a tool for corresponding adjustment devices for height or lateral adjustment are accessible.

Through the lower recess 41 is also in the figures 1 and 2 a release element 66 can be seen.

The release element 66 and preferably also the height adjustment element 73 and the lateral adjustment element 74 are part of a fastening device 10, as illustrated in FIG Figures 3 to 11 is to be described in more detail below and by means of which the screen 2 can be fixed to a respective side frame 4 of the drawer 1 .

As in the Figures 3 , 4 and 6 shown, the fastening device 10 has a screen carrier 7 that can be arranged on the screen 2 and an adapter 6 that can be arranged on the frame 4 and to which the screen carrier 7 can be fixed.

In the embodiment variant shown here, the panel support 7 is designed as a U-shaped piece of sheet metal, on the closed end of which there are openings for the passage of connecting elements such as screws for fixing the panel 2 in place.

The opposite open end face of the panel support 7 is used to hold the adapter 6, onto which the panel support 7 together with the panel 2 can be pushed during assembly of the panel 2 on the frame 4 of the drawer 1.

The panel support 7 also has two connecting elements 72 which are accommodated between the side walls 71 of the panel support 7 arranged parallel to one another and are fixed in place extending in the X-direction in receiving openings provided for this purpose in the side walls 71 of the panel support 7 .

The adapter 6 has at least one side wall 61 with a mounting foot 618 formed thereon for attachment to the frame 4 . The mounting base 618 preferably extends into a bottom channel of the frame 4, to which a bottom 5 of the drawer 1 can be fixed

In the preferred embodiment variant shown here, the adapter 6 has a second side wall 62 which is fastened to the first side wall 61, for example screwed or riveted. The shape of the second side wall 62 corresponds to the mirror image of the shape of the first side wall 61 of the adapter 6, except for the absence of the mounting foot 618.

It is also conceivable to form the adapter 6 with only one side wall.

Arranged between the side walls 61, 62 of the adapter 6 are two catch devices with a respective wedge slide 63, 64, with which a respective connecting element 72 arranged on the panel support 7 can be fixed in a mounting position on the adapter 6.

Depending on the height of the screen support, it is also conceivable to provide more than two connecting elements 72 on the screen support 7 and a number of catch devices corresponding to the number of connecting elements 72 with respective wedge slides 63, 64.

3 shows the adapter 6 with the front side wall 61 omitted to show the arrangement of the wedge slides 63, 64 and their shape.

Each of the side walls 61, 62 of the adapter 6 has two retaining grooves 611, 612, 621, 622, in which the connecting elements 72 of the panel support 7 lie in the assembled position of the adapter 6 and the panel support 7. The fixing position of the connecting elements 72 in the retaining grooves 611, 612, 621, 622 is in 3 shown.

As in 3 It can also be seen that the wedge slides 63, 64 are coupled to an unlocking device 66 for the catching device, with which the wedge slides 63, 64 can be moved between the in 3 fixing position shown and one in 4 shown release position are movable.

The wedge slides 63, 64 are held on the adapter 6 in a linearly displaceable manner. For this purpose, each of the wedge slides 63, 64 has at least one guide cam 636, 646, which is guided in a respective guide groove 613, 614, 623, 624 of the side walls 61, 62 of the adapter. The guide grooves 613, 614, 623, 624 are designed as elongated holes that extend in the Z direction.

To move the wedge slides 63, 64 from the fixing position to the release position, the unlocking device 66 can be actuated from the outside of a frame 4 with a tool, for example a screwdriver.

The unlocking device 66 preferably has a wheel, which is designed as a gear wheel in the preferred embodiment shown here, which is arranged on the side walls 61, 62 of the adapter 6 such that it can rotate about an axis of rotation oriented perpendicularly to the surfaces of the side walls 61, 62.

The gear wheel engages with its teeth in a drive edge 631, designed here as a rack, of the first wedge slide 63 and, by turning the gear wheel, counterclockwise in the exemplary embodiment shown, causes the first wedge slide 63 to be displaced in the direction of the release position of the wedge slides 63, 64. in the embodiment shown here in the Z-direction upwards.

As in the Figures 3 and 4 It can also be seen that the first wedge slide 63 has a guide bar 634, which touches a lower edge of the second wedge slide 64 during the upward displacement and moves the second wedge slide 64 with it as the first wedge slide 63 moves further upwards.

In order to keep the two wedge slides 63, 64 in the fixing position without external force being applied, spring elements 65, preferably in the form of helical compression springs, are placed on the guide webs 634, 644, which support the wedge slides 63, 64 on the side walls 61, 62 of the adapter 6 press into the fixed position.

Each of the wedge slides 63, 64 also has a respective fixing groove 622, 632, in which the respective connecting element 72 of the panel support 7 is accommodated in the fixing position and thus prevents the connecting element 72 from moving in the release direction L.

The shifting of wedge slides 63, 64 into the release position, as shown in 4 is shown causes the connecting elements 72 to be released for movement in the release direction L, which allows detachment of the panel support 7 from the adapter 6 in the release direction L.

In order to be able to preload the wedge slides 63, 64 in the release position, the first wedge slide 63, which is coupled to the unlocking device 66, can be latched in the release position.

This is how in the Figures 4, 5 and 6 is shown, on a side wall 61 of the adapter 6 there is a latching point 617 in which a latching element 635 arranged on the first wedge slide 63 can be latched. The detent position is in figure 5 shown in an enlarged view.

The guide cam 636 of the first wedge slide 63 is preferably designed as a pivot bearing of the first wedge slide 63 so that the latching element 635 of the first wedge slide 63 can latch in this latching point 617 .

As a result, the wedge slide 63 can be pivoted slightly in the direction of the panel carrier 7 after it has been moved into the release position about the guide cam 636 .

The pivoting movement is brought about on the one hand by the force component of the gear wheel coupling between the teeth of the unlocking device 66 and those of the drive edge 631 of the first wedge slide 63 .

At the same time, the wedge slide 63 is guided during its movement from the fixing position to the release position by the contact of the latching element 635 against a wall of a recess in the side wall 61 that extends parallel to the guide grooves 613, 614, so that the wedge slide 63 only engages when it reaches the latching point 617 can pivot in the direction of the panel support 7 in the locking point 617.

A fastening device 10 configured in this way makes it possible for fastening the panel 2 and the frame 4 to be able to fasten the panel 2 by means of a single attachment movement parallel to the normal in a front surface of the panel 2 .

By placing the panel support 7 on the adapter 6, the panel support 7 together with the panel 2 attached thereto can be pushed onto the adapter 6 counter to the release direction L.

The connecting elements 72 get into the retaining grooves 611, 612, 621, 622 in the front side of the side walls 61, 62 of the adapter 6 facing the panel support 7 until one of the connecting elements 72 touches a control edge 637 of the first wedge slide 63.

By further advancing the panel carrier 7 and thus the connecting element 72 and the associated pivoting movement of the first wedge slide 63 around the guide cam 636 of the first wedge slide 63, the latching element 635 is pushed out of the latching point 617 of the adapter 6.

The spring force of the spring elements 65 then triggers a downward movement of the wedge slides 63, 64 into the fixing position. The wedge slides 63, 64 overlap the connecting elements 72 so that these are fixed in the respective fixing groove 622, 632 of the respective wedge slide 63, 64 and the respective holding groove 611, 612, 621, 622 of the side walls 61, 62 of the adapter 6.

The panel support 7 is thus fixed to the adapter 6 .

When detaching the panel 2 from the frame 4 with such a fastening device 10 , the first connecting element 72 is first unlocked by moving the first wedge slide 63 by actuating the release element 66 .

The second connecting element 72 is then unlocked by moving the second wedge slide 64 . The displacement of the second wedge slide 64 takes place as a result of the continued displacement of the first wedge slide 63.

In order to prevent the aperture support 7 from accidentally falling off the adapter 6 with the aperture 2 attached to it, as shown in FIGS Figures 6 to 11 also shown that at least one side wall 61, 62 of the adapter 6 and one of these at least one opposite side wall 71, 75 of the panel support 7 is formed with a cooperating latching device.

As a result, the diaphragm support 7 is held on the adapter 6 so that it can be displaced linearly to a limited extent in the release direction L when the capture device(s) is/are released. The latching device is formed here by latching elements 76 , 619 , 629 which are preferably integrally formed and are resilient vertically to the side walls of the adapter 6 and/or the panel support 7 .

while in the Figures 2 to 10 an adapter corresponding in its height extension in direction z to about the height of the panel support 7 is shown, the one in figure 11 shown adapter 6 stages. A region close to the panel support 7 is designed to be adapted to the height of the panel support 7 . In contrast, an area remote from the panel support 7 has an extension in the Z direction that is greater than that of the panel support.

This latching device acts to latch the panel support 7 on the adapter 6 in a release position of the catching device/s.

The latching elements arranged on the panel support 7 are preferably designed in the form of two holding webs 76 . The holding webs 76 are preferably designed as tongues bent over in a U-shape, which extend inward from an upper edge of the side walls 71, 75 of the panel support 7 into an intermediate space between the side walls 71, 75 of the panel support 7 and thereby fill this intermediate space in the region of these holding webs 76 constrict.

The retaining lugs 619, 629 of the adapter 6 are preferably formed on the upper end of the respective side walls 61, 62 of the adapter, which end projects towards the panel support 7. The retaining lugs 619, 629 are aligned in such a way that they protrude slightly beyond the outer surfaces of the side walls 61, 62.

The retaining lugs 619, 629 ensure that when the adapter is pushed together with the panel support 7, as shown in FIGS figures 8 and 9 is shown, the retaining lugs 619, 629 abut the side walls of the retaining webs 76 and thus prevent the panel support 7 from being pulled off the adapter 6 .

When the panel support 7 is slid onto the adapter 6, the holding lugs 619, 629 are elastically pressed inwards by the inner sides of the side walls 71, 75 when the panel support 7 is slid onto the adapter 6 and can thus be guided past the holding webs 76.

To the aperture carrier 7 from the figures 8 and 9 To be able to completely remove the position shown from the adapter 6, it is necessary to lift the diaphragm support 7 slightly relative to the adapter 6. This position is in figure 10 shown.

As in this one figure 10 As can be seen, the retaining webs 76 reach a position above the retaining lugs 619, 629 after the panel carrier 7 has been raised, so that the panel carrier 7 can be removed from the adapter 6 in the horizontal direction in the release direction L.

As in the Figures 6 to 11 is also shown, at the front end of the upper edge of the side walls 71, 75 of the panel support 7 facing the adapter 6 is formed at least one support surface 77 which, when the panel support 7 is pushed onto the adapter 6, enables a pre-positioning of the connecting elements 72 in the vertical direction to the Enable adapter 6. Furthermore, the connecting elements 72 are arranged in the frame longitudinal direction Y at a shorter distance from the panel 2 on the side walls 71, 75 in the panel support than the support surfaces 77.

According to the invention, the support surfaces 77 are also designed as sheet metal tongues which are bent towards one another by the respective side walls 71, 75 of the panel support 7.

Another embodiment of a fastening device is based on the Figures 12 to 15 described.

As in figure 14 is shown, a cover cap 8 is placed on the panel support 7 to cover part of the technology of the side frame.

The cover cap 8 is, as in figure 13 shown, is essentially of an approximately U-shaped cross-section and can be slipped onto the blind carrier from above in a simple manner.

The cover cap 8 has two top walls 81, 82 that at least partially cover the side walls 71 of the panel support 7, and a connecting web 83 that connects the side walls 81, 82 to one another and, in the assembled state, covers the upper edge of the panel support 7 that extends horizontally in the longitudinal direction L of the side frame 4 , and a holding tab 84, which is preferably angled vertically downwards from the connecting web 83 and extends parallel to the panel 2 in the direction of the free ends of the top walls 81, 82.

The length of the cover cap 8 in the longitudinal direction L of the side frame 4 can be dimensioned in such a way that it extends not only over the panel support 7 or part of it, but also away from the panel 2 completely or partially over the adapter 6 and, if necessary, up to extends into the parts of the side frame 4 adjoining the adapter 6 .

The retaining tab 84 serves to fix the cover cap 8 against displacement in the longitudinal direction L of the side frame 4.

As exemplified in figure 12 is shown, for this purpose a finger 78, which is resiliently arranged in the longitudinal direction of the frame, protrudes from an opening 79 in the area of an end face of the panel support 7 facing the cover 2 into the opening 79, with which the retaining tab 84 protruding into the opening 79 is attached to one of the cover supports 7 facing surface of the aperture 2 can be pressed.

The material thickness of the retaining tab 84 is dimensioned such that a contact surface of the retaining tab 84 facing the panel 2 only reaches a plane defined by the contact surface of the panel carrier 7 on the panel 2 when force is exerted by the finger 78 .

The spring force of the finger 78 is aligned in the direction of the panel 2 and also ensures that the covering cap 8 always rests flat on the back of the panel 2 after it has been pushed onto the panel support 7 .

The finger 78 is preferably fixed to the panel support 7 or designed as part of the panel support 7 .

To fix the cover cap 8 against lifting, as in figure 15 is shown, on a free end of one of the top walls 81, 82 of the covering cap 8 there is a latching web 87 for latching with a latching receptacle of the panel support 7, the adapter 6 or the frame 4, preferably in the rear area of one of the top walls remote from the panel 2, in figure 15 formed on the top wall 82 near the interior of the drawer.

How further in the figures 13 and 15 shown, the free lower edge of the top wall 82 in the area closer to the panel 2 is bent approximately at right angles inwards, i.e. towards the top wall 81, and preferably serves as a holding web 85.

The free lower edge of the opposite top wall 81 is preferably designed inwards as a pressure web 86 along its entire length. For this purpose, the lower free end of the top wall is bent in a parallel offset manner and preferably rests against an outer wall of the frame 4 after the cover cap 8 has been fitted.

In particular, the locking device allows a simple and safe release of a panel 2 from a frame 4 with the fastening device described above.

In a first method step for detaching the panel 2 from the frame 4 , a first connecting element 72 of the panel support 7 is unlocked by moving a first wedge slide 63 by actuating a release element of the unlocking device 66 .

A second connecting element 72 is then unlocked by moving a second wedge slide 64 by moving the first wedge slide 63.

In this position, the panel support 7 has already been slightly displaced in the release direction L relative to the adapter 6, but cannot yet be removed further in the release direction L, since in this position further displacement of the panel support 7 is prevented by the retaining webs 76, which hold the retaining lugs 619 , 629 get behind.

Accordingly, in a third method step, the latching between the adapter 6 and the panel support 7 is released by lifting the panel support 7 and finally removing the panel support 7 with the panel 2 attached to it from the adapter 6.
