Description

Drawer with two side frames and with a panel

The present invention relates to a drawer with two side frames and with a panel, which is fixed to the front end edges of the side frames and at least vertically adjustable relative to the drawer.

Drawers of the aforementioned type are known in many embodiments - especially in terms of the connection between the panel and drawer known.

The present invention has for its object to provide a drawer of the generic type, which is characterized by a particularly simple design and inexpensive to produce and easy to install mounting the aperture on the drawer in the rest.

This object is achieved in that two mounting plates are provided with a Höhenverstellexzenter and a clamping eccentric receiving housing on the panel on the opposite side of the side frames and that the side frames have an outgoing from their front side cutout, in which the Höhenverstellexzenter the side frames supporting protrude and that the side frames are equipped with thrust bearings for the clamping eccentric, so that a tightening of the panel against the end faces of the side frames by means of the clamping eccentric is possible.

Such a construction ultimately requires less and simple and inexpensive producible items and allows quick and easy installation including an adjustment of a panel on the drawer. By the Höhenverstellexzenter the aperture is already supported and held in a vertical manner in a kind of pre-assembly, the aperture can then be tightened and set by pressing the clamping eccentric finally against the front sides of the side frames. Further features of the invention are the subject of dependent claims.

In the accompanying drawings exemplary embodiments of the invention are shown, which are described in more detail below.

In the first embodiment of the invention shown in Figures 1 to 19 is denoted by the reference numeral 1, a diaphragm of a not further illustrated drawer and by the reference numeral 2, a side frame of the drawer, a complete drawer of course has a further side frame 2, which is parallel to first side frame runs. It is in the present case exclusively about the connection between the side frames 2 and the panel 1 to accomplish in a simple manner, so that the representation of only one side frame 2 and the panel 1 is sufficient to convey the inventive idea.

At the aperture 1 are at a distance from the side frames 2 to each other and these side frames 2 opposite mounting plates 3 screwed, which are equipped with horizontally extending slots 3a, which are penetrated by the (not shown here) mounting screws. Due to the elongation, ie, a horizontal orientation of the panel 1 relative to the side frames 2 is possible.

The mounting plates 3 have a housing 4, which consists of a preferably integrally connected to the mounting plate 3 parallel to the respective gene side frame 2 extending flange 5 and a clamping plate 6 is formed, which is connected to the mounting plate 3 in the other hinge-like manner. The clamping plate 6 has for this purpose a slot 7a, in which provided on the mounting plate 3 lugs 8 can engage to realize the hinge-like compound. This results in particular and very clearly from FIGS. 3 and 4.

Said housing 4 receives a Höhenverstellexzenter 9 and a clamping eccentric 10, wherein the Höhenverstellexzenter 9 engages in the mounted state in a recess 110 of the respective side frame 2 and the panel 1 is supported in the vertical direction. The clamping eccentric 10 cooperates in the assembled state with an abutment 120 of the side frame 2, so that it is possible, by operating the clamping eccentric 10, to pull the panel 1 firmly against the end faces of the side frames 2. The clamping eccentric 10 is integrally formed on a cover plate 11, which conceals, after tightening the clamping eccentric 10 and the associated tightening of the panel 1 against the end edges of the side frames 2 in an alignment with the Höhenverstellexzenter 9 through opening 12 of the clamping plate 6, which is clear from Figure 14 in particular.

The clamping eccentric 10 passes through the clamping plate 6 in the region of an approximately keyhole-like opening 13 and thus can be pushed through this keyhole-like opening only in a predetermined position, since the clamping eccentric 10 is provided with an integrally formed nose 10a, which is the insertion of the clamping eccentric 10 through the opening 13th only permissible if the nose 10a is congruent to a slot-like recess 13a of the opening 13. This possible insertion position is shown very clearly in FIG.

After inserting the clamping eccentric 10 in the clamping plate 6 hingedly connected to the fastening plate 3, the clamping eccentric 10 is brought by pivoting out of the position shown in FIG. 2 by 180 ° into a position according to FIGS. 7 to 13. In this pivotal position a separation of clamping plate 6 and clamping eccentric 10 is no longer possible. The panel 1 is now moved out of the position shown in Figure 7 in the direction of the end faces of the side frames 2 until the Höhenverstellexzenter 9 engages in the recess 110 of the side frame 2. In this way, a pre-assembly position of the panel 1 that is positive in the vertical direction is given relative to the side frames 2. This intermediate position is very clear from Figures 8 to

10th

In the course of assembly, the clamping plate 6 is now pivoted to the side frame 2 and brought into a parallel position to the flange 5 connected to the mounting plate 3. In this pivoting passes through the

Clamping eccentric 10 an opening 14 of the side frame 2, which is located in the region of the thrust bearing 120 of the side frame 2, on the side facing away from the panel 1 of said abutment 120th

As particularly shown in Figures 10 and 13, the clamping eccentric 10 is a

Provided spring 15, which is slightly compressed during insertion of the clamping eccentric 10 in the opening 14 and relaxed after being pushed through the opening 14, so that the spring 14 now rests on the clamping plate 6 opposite inner side of the side frame 2, and in FIG 13 shows. This is the case formed from the flange 5 and the clamping plate 6

4 closed and an opening or pivoting back of the clamping plate 6 is only possible if the spring 14 is pushed back from its position according to Figure 13 with a corresponding effort again.

In this mounting position engages an end bearing journal 16 of the clamping eccentric 10 in a bearing bore 17 of the flange 5 a. This too can be seen very clearly from FIG.

The clamping eccentric 10 is thus stored sufficiently well and can be easily rotated around its axis by actuation of the cover plate 11.

The cover plate 11 is provided on its resting on the clamping plate 6 page with characteristics I Ia, which engage in different mounting intermediate positions in therefor attached to the clamping plate 6 locking openings 6a and during the pivoting in a circular arc, embossed in the cover plate 6 groove 6b are performed.

Will now the cover plate 11 and thus also the clamping eccentric 10 from the position shown in Figures 11 to 17, in which the Höhenverstellexzenter 9 is still freely accessible and a height adjustment of the aperture 1 can be performed in the from Figures 14, 16 and Pivoted 18 recognizable position, the Höhenverstellexzenter 9 is concealed on the one hand and on the other hand a clamping curve 10c of the clamping eccentric 10 is pressed against the abutment 120 of the side frame 2, as shown particularly clearly in FIG. By this pressing the

Tension curve 10c to the anvil 120 of the side frame 2, the panel 1 is tightened firmly against the front side of the side frame 2 and set against the side frame 2.

Of course, the above-described processes take place in the region of both side frames 2 of a drawer, so that the panel 1 can be easily attached to the drawer, adjusted in height and then finally fixed to the side frames 2.

At the same time the respective Höhenverstellexzenter 9 is covered, so that an operation of this Höhenverstellexzenter 9 is not possible. If a readjustment of the height of the diaphragm 1 is required, it is necessary to first pivot the clamping eccentrics back into a position, for example according to FIG. 11, so that the height adjustment eccentrics 9 are now freely accessible again and allow their height to be adjusted. In this case, the panel 1 is not firmly used on the end faces of the side frames, so that the height adjustment is feasible without any problem.

Subsequently, the clamping eccentric 10 are pivoted back into their operative position according to, for example, FIG. 16, and the diaphragm 1 is used on the end faces of the side frames 2.

In the embodiment shown in Figures 1 to 19, the Höhenverstellexzenter 9 and the clamping eccentric 10 are offset in height to each other, wherein in concrete embodiment, the Höhenverstellexzenter 9 are located above the clamping eccentric 10. Of course, a reversal in the sense would be possible here that the clamping eccentric 10 are above the Höhenverstellexzenter 9.

An alternative construction is shown in Figures 20 to 26. Here are Höhenverstellexzenter 9 and clamping eccentric 10 in a horizontally one behind the other, in which case the Höhenverstellexzenter 9 of the aperture 1 adjacent and the clamping eccentric 10 further away from the aperture 1 as the Höhenverstellexzenter 9.

Accordingly, the counter bearing 120 is mounted for the clamping eccentric 10 behind the recess 110 of the side frame 2, in which the Höhenverstellexzenter 9 engages, as Figure 22 shows.

Otherwise, the function and mode of operation of the construction shown in FIGS. 20 to 26 are identical to the construction according to the exemplary embodiment according to FIGS. 1 to 19.

Again, covers the cover plate 11 in the final assembly state, in which the panel 1 is used firmly on the end faces of the side frames 2, the respective Höhenverstellexzenter 9, and this figure 26 makes clear.

Figures 27 to 39 show an exemplary embodiment of the invention, in which, in accordance with the previously described exemplary embodiments of Höhenverstellexzenter 9 while maintaining its rotational ability on the flange 5 of the mounting plate 3 is fixed while the clamping eccentric 9 has a different design and definition than in the past shown variants.

Höhenverstellexzenter 9 and clamping eccentric 10 are in turn arranged one above the other, as the arrangement of recess 110 and abutment 120 in Figure 32, 33 shows. The clamping eccentric 10 passes through the clamping plate 6 in the region of a vertically aligned elongated hole 18, which is provided in its upper region with locking cams 19, between which the clamping eccentric 10 in a NuIl- or basic position is maintained. In addition, the flange 5 is provided with a likewise vertically extending slot 20 which is located in alignment with the locking cam 19 of the slot 18 within the clamping plate 6 with locking cam 21. Between these locking cams 21, a bearing pin 22 of the clamping eccentric 10 is held.

Figures 29 to 31 show the assembly process of the clamping eccentric 10, the corresponding figures 29, 31 inserted into the slot 18 and then pressed according to Figure 31 upwards into its zero position / home position, where it is held by the locking cam 19. The congruent locking cam 21 in

Flange 5 reinforce the fixation of the clamping eccentric 10 in the basic position / zero position after attaching the clamping plate. 6

The clamping eccentric 10 engages in its active position a curved counter bearing 120 of the side frame 2, which, as shown in FIGS. 32 and 34a and 34b, can be pushed out of the side frame 2 by stamping and bending technique (FIG. 32) by a deep drawing process an undercut (Figure 34a) or as a separate component made of plastic, sheet metal or zinc die casting (Figure 34b) can be made. The design of the tensioning cam-type abutment 120 and / or the design of the corresponding abutment region of the clamping eccentric 10 can be influenced on the achievable clamping effect, which is required for the secure determination of a diaphragm at the front edges of the side frames 2.

Also in this embodiment is covered by the cover plate 11 to which the clamping eccentric 10 is formed in the end position that opening through which the Höhenverstellexzenter 9 is accessible for the purpose of height adjustment. This can be seen in particular from FIGS. 35 and 36.

As can be seen in particular from Figures 37 and 39a to 39d, the

Bearing journals 22 of the clamping eccentric 10 may be provided at its front end with thickenings 22 a, to effect an axial locking of the clamping eccentric 10 relative to the flange 5 of the mounting plate 3. In all embodiments shown so far, the clamping plate 6 is hingedly connected to the mounting plate 3 and is brought only in the course of assembly in a parallel position to the flange 5 of the mounting plate 3 to form a substantially closed housing 4, which in each case the height adjustment eccentric. 9 and the clamping eccentric 10 receives.

FIGS. 40 to 44 show a possible solution for a housing 4 that can be finished before assembly.

Here, as can be seen from FIGS. 40 and 41, the height adjustment eccentric 9 is provided with a peripheral groove 9a, which permits the positive insertion of the said height adjustment eccentric 9 into a corresponding receiving opening in the form of an oblong hole 18 of the clamping plate 6, like FIGS. 40 and 41 demonstrate.

Subsequently, the clamping eccentric 10 is also inserted into the slot 18 and fixed between the cam 19. Now, the clamping plate 6 can be pivoted into a parallel position to the flange 5 of the mounting plate 3, wherein the flange 5 facing the end of Höhenverstellexzenters 9 engages in a bore 5 a of the flange 5, to subsequently while maintaining the rotation of the

Höhenverstellexzenters 9 against the flange 5 to be riveted. It then creates a closed housing 4, as the figures 42 and 43 make clear. The mounting plate 3 with the housing 4, which accommodates the Höhenverstellexzenter 9 as well as the clamping eccentric 10, can be pushed from the front side of a side frame 2 on this and tightened by pivoting the cover plate 11 and thus of the clamping eccentric 10 to the front end of the side frame 2 become.

After a required height adjustment and the pivoting of the cover plate 11 in the clamping position is then, what makes Figure 44 clearly, again the access opening for Höhenverstellexzenter 9 covered.

If the components arranged rigidly to one another, namely the fastening plate 3 with its flange 5 and the clamping plate 6, differing from the above-described embodiment example- not held together by the riveting of Höhenverstellexzen- age 9, a correspondingly rigid arrangement can be created in that after the joining and folding of said components, the common contact surfaces z. B. by spot welding or by riveting together.

Also in the figures 45 to 54, an embodiment is shown, in which even before the final assembly, a rigid housing 4 of the flange 5, the mounting plate 3 and the clamping plate 6 is formed.

First, the Höhenverstellexzenter 9 is riveted to the flange 5 of the mounting plate 3 while maintaining its rotation. The clamping plate 6 can then be connected to the mounting plate 3, in the illustrated embodiment by integrally formed on the clamping plate 6 retaining lugs 6c, which can be inserted through corresponding slots 3b in the mounting plate and then bent, as can be seen specifically from Figures 45 and 47 ,

Subsequently, the clamping eccentric 10 can be inserted through an opening 6d through and provisionally fixed to this by integrally formed locking lugs 10d. For final assembly, the preassembled unit - consisting of mounting plate 3 and housing 4- pushed on a frontal end of a side frame 2 of the clamping eccentric 10 in the axial direction after sliding on until the locking lugs 10d engage behind the side frame 2, as Figure 50 this clearly shows. Now the connection between the housing 4 and the side frame 2 is made, then - after a possibly carried out Höheneinstellung- the clamping eccentric 10 by pivoting the cover plate 11 while concealing the access opening for Höhenverstellexzenter 9 are pivoted into its clamping position.

FIGS. 54a to 54e clearly show that the latching lugs 10d of the clamping eccentric 10 are of different lengths, so that they can rest against corresponding contact surfaces of the clamping plate 6 at the preassembly position or the side frame 2 in the final assembly position. The embodiments described last are characterized by a prefabricated, closed housing 4, which can be delivered in preassembled position.
