Description

The present invention relates to a drawer with two sidewalls and one front panel, which can be fixed on the front end edges of the sidewalls and can be adjusted at least vertically relative to the drawer.

Drawers of this type are known in a variety of embodiments, in particular with regard to the connection of the front panel and the drawer.

The present invention is the creation of a drawer of this kind, which will differ even more simple and cheap design, and also from the point of view of installation technology more simple mounting of the front panel on the drawer.

This problem is solved in the invention due to the fact that on the front panel from the inside, opposite the sidewalls, there are two mounting strips with a housing accommodating one eccentric for height adjustment and one tension eccentric, and the sidewalls have a recess starting from their end sides, in which the eccentrics enter for height adjustment, providing an emphasis for the sidewalls, and the sidewalls are equipped with counter supports for tensioning eccentrics, which make it possible to pull the front panel to the end sides of the sidewalls yazhnyh eccentrics, each building on the mounting rail comprises a flange fixedly connected to the mounting strip formed preferably as a single element and a tension bar connected pivotably to the fastening strip by means of the hinge type connection.

This kind of design, after all, requires just a few simple and cheap individual parts and makes it easy and quick to install, including adjusting, the front panel on the drawer. Using eccentrics to adjust the height in a kind of pre-installation position, the front panel is supported and held already in the vertical direction, and the front panel, after probably performing the necessary height adjustment, can then be finally tightened and fixed on the end sides of the sidewalls, using tension eccentrics.

Other features of the invention are disclosed in the dependent claims.

In the first embodiment shown in Figures 1 to 19, reference numeral 1 denotes a front panel of a drawer not shown here, and reference numeral 2 denotes a drawer sidewall, the entire drawer, of course, having another sidewall 2 that runs parallel to the first sidewall. In the present case, the task is solely to make the connection between the sidewalls 2 and the front panel 1 in the simplest way, therefore, to represent only one sidewall 2 and the front panel 1 is enough to convey the idea of the invention.

On the front panel 1 at a distance of the sidewalls 2 relative to each other and opposite these sidewalls 2 are fastened brackets 3, which are equipped with horizontal longitudinal grooves 3a, through which the fastening screws (not shown here) pass. That is, due to the longitudinal grooves 3a, horizontal alignment of the front panel 1 with respect to the sidewalls 2 is possible here.

The fastening strips 3 have a housing 4, which is predominantly connected with the fastening bar 3 into a single element parallel to the corresponding sidewall 2 by the flange 5 and the tension bar 6, which is otherwise connected to the fastening bar 3 by a joint similar to a hinge. The tension bar 6 has for these purposes a slot 7a, into which protrusions 8 provided for on the mounting bar 3 can be inserted for realizing a hinge-like connection. This, in particular, is very clearly shown in figures 3 and 4.

The housing 4 accommodates an eccentric 9 for height adjustment and a tension eccentric 10, and the eccentric 9 for height adjustment in the assembled state enters the recess 110 of the corresponding sidewall 2 and props the front panel 1 in the vertical direction. The tensioning eccentric interacts in a mounted state with the counter support 120 of the sidewall 2, due to which, using the tensioning eccentric 10, the front panel 1 can be fixed on the end sides of the sidewalls 2. The tensioning eccentric 10 is formed by a single element on the plug 11, which after tightening the tensioning eccentric 10 and the associated with it, fixing the front panel 1 at the end edges of the sidewalls 2 closes the through hole 12 of the tension bar 6, which is at the same level with the eccentric 9 for height adjustment, which, in particular, is clearly shown in figure 14.

The tension eccentric 10 passes through the tension bar 6 in the region of the hole 13, which has approximately the shape of a key hole, and thereby it can be passed through this hole, the shape of a key, only in a certain position, since the tension eccentric 10 is equipped with a molded protrusion 10a, which allows the introduction of the tension eccentric 10 through the hole 13 only if the protrusion 10a is at the same level with the front recess 13a of the hole 13. This possible insertion position is very clearly shown in figure 2.

After introducing the tension eccentric 10 into the tension bar 6 connected by a hinge-like connection to the fixing bar 3, the tension eccentric 10 is moved by turning from the position shown in figure 2, 180 ° to the position according to figures 7 to 13. In this rotation position, divide the tension The bar 6 and the tensioning cam 10 are no longer possible.

Now the front panel 1 is displaced from the position shown in figure 1, in the direction of the end sides of the sidewalls 2, until the eccentric 9 for height adjustment enters the recess 110 of the sidewall 2. Thus, a pre-installation position with a geometric closure in the vertical direction for the front panel 1 is obtained relative to the sidewalls 2. This intermediate position is clearly shown in figures 8 to 10.

In the course of further installation, the tension bar 6 is turned to the sidewall 2 and brought into a position parallel to the flange 5 connected to the mounting bar 3. In this rotation, the tension eccentric 10 passes through the hole 14 of the sidewall 2, which is located in the area of the counter support 120 of the sidewall 2, and it is on the side of the specified counter supports 120 facing from the front panel 1.

As shown in particular in figures 10 and 13, the tension eccentric 10 is equipped with a spring 15, which, when the tension eccentric 10 is inserted into the hole 14, contracts slightly and loosens again after being pressed through the hole 14, so that the spring 14 now abuts against the inside of the sidewall 2, located opposite the tension bar 6, as shown in figure 13. Thus, the housing 4, formed by the flange 5 and the tension bar 6, is closed and the opening or rotation of the tension bar 6 back is only possible if the spring 14 is again bent back hell from its position according to figure 13 with the corresponding effort.

In this mounting position, the end root neck 16 of the tensioning cam 10 enters the hole 17 of the bearing of the flange 5. This can also be very clearly seen in figure 13.

Thus, the tension eccentric 10 has a fairly good support, and it can be conveniently rotated around its axis, using the plug 11.

The plug 11 is equipped on the side adjacent to the tension plate 6 with protrusions 11a, which in various intermediate mounting positions are included in the fixing holes made for this on the tension plate 6 and pass through the groove 6b made in the plug 6 in the form of a semicircular arc.

If you now turn the plug 11, and thereby also the tension eccentric 10, from the position shown in figures 11 to 17, in which the eccentric 9 for height adjustment is still freely accessible and you can adjust the front panel 1 in height, to the position shown in figures 14, 16 and 18, then, on the one hand, the eccentric 9 is closed for height adjustment, and on the other hand, the clamping eccentric 10 from the tension eccentric 10 is pressed against the counter support 120 of the sidewall 2, as is particularly clearly seen in figure 16. Due to this clamp clamp clamp Centric 10c to the counter support 120 of the sidewall 2, the front panel 1 is firmly attracted to the end side of the sidewall 2 and is fixed relative to the sidewall 2.

The processes described above occur, of course, in the area of both sides of the drawer 2, due to which it is possible to easily attach the front panel 1 to the drawer, adjust it in height and then finally fix it on the sidewalls 2.

At the same time, the corresponding eccentric 9 for height adjustment is closed, so it is no longer possible to use this eccentric 9 for height adjustment. If it is necessary to adjust the position of the front panel 1 in height, it is necessary to first turn the tension eccentric again to a position, for example, according to figure 11, so that now the eccentric 9 for height adjustment is again freely accessible, and, actuating it, provide height adjustment the front panel 1. At the same time, the front panel 1 is not strongly pulled to the end sides of the sidewalls, so you can easily make height adjustments.

Then, the tension eccentrics 10 are again rotated to their working position, for example, according to figure 16, and the front panel is attracted to the end sides of the sidewalls 2.

In the example embodiment of the invention shown in figures 1 to 19, the eccentric 9 for height adjustment and the tension eccentric 10 are offset in height relative to each other, and in a specific embodiment, the eccentrics 9 for height adjustment are above the tension eccentrics 10. needless to say, it could have been the other way around in the sense that the tension eccentrics 10 would be located above the eccentrics 9 for height adjustment.

An alternative construction to this is shown in figures 20 to 26. Here, the eccentric 9 for height adjustment and the tension eccentric are located horizontally one after the other, in this case the eccentric 9 for height adjustment is next to the front panel 1, and the tension eccentric 10 is located further from the front panel 1 than the eccentric 9 for height adjustment.

Accordingly, the counter support 120 for the tension eccentric 10 is located behind the recess 110 of the sidewall 2, which includes the eccentric 9 for height adjustment, as shown in figure 22. Otherwise, the function and method of action of the structure shown in figures 20 to 26 are identical to the structure according to example implementation of the invention according to figures 1 to 19.

Here, too, the plug 11 hides in the final mounted state, in which the front panel 1 is tightly drawn to the end sides of the sidewalls 2, the corresponding eccentric 9 for height adjustment, as shown clearly in figure 26.

Figures 27 to 39 show an example implementation of the invention, in which, as in the previously described examples of implementation, the eccentric 9 for height adjustment is mounted on the flange 5 of the mounting plate 3 while maintaining rotation, while the tension eccentric 9 is made and fixed otherwise than in the previously shown options.

The eccentric 9 for height adjustment and the tension eccentric 10 are again located one above the other, as shown by the location of the recess 110 and the counter support 120 in figures 32, 33. The tension eccentric 10 passes through the tension bar 6 in the region of the vertically directed longitudinal groove 18, which in its the upper region is equipped with locking protrusions 19, between which the tension eccentric 10 is held in the zero or main position. In addition, the flange 5 is also equipped with a vertically extending longitudinal groove 20, in which the locking protrusions 21 are made, which are flush with the locking protrusions 19 of the longitudinal groove 18 inside the tension bar 6. Between these locking protrusions 21, the main neck 22 of the tension eccentric 10 is held.

Figures 29 to 31 show the installation process of the tensioning clown 10, which, according to figures 29, 31, is inserted into the longitudinal groove 18 and then, in accordance with figure 31, is pressed up into its zero / initial position, where it is held by the locking protrusions 19. Located on one level locking tabs 21 in the flange 5 enhance the fixation of the tension eccentric 10 in the initial / zero position after the tension bar 6 is displaced.

The tension eccentric 10 extends in its working position beyond the eccentric support 120 of the sidewall 2, which, as shown in figures 32, 34a and 34b, can be performed on the sidewall 2 (figure 32) by bending with a stamp, can be made in the process of deep drawing with undercut (figure 34a) or is made as a separate element of plastic, sheet metal or zinc, molded under pressure (figure 34b). By making the counter-support 120 in the form of a clamping eccentric and / or by performing the corresponding abutment region of the tensioning eccentric 10, it is possible to influence the obtained clamping action, which is necessary for reliable fixation of the front panel at the end edges of the sidewalls 2.

Also in this embodiment, the plug 11, on which the tension eccentric 10 is formed, in the final position closes the hole through which the eccentric 9 for height adjustment is accessible for height adjustment purposes. This, in particular, is seen in figures 35 and 36.

As, in particular, it can be seen in Figures 37 and 39a through 39d, the main neck 22 of the tension eccentric 10 can be equipped with clamps 22a at its end end, which provide axial fixation of the tension eccentric 10 relative to the flange 5 of the mounting plate 3.

In all shown examples of implementation of the invention, the tension plate 6 is pivotally connected to the mounting plate 3 and only during installation is translated into a position parallel to the flange 5 of the mounting plate 3, to form a basically closed housing 4, which, accordingly, accommodates an eccentric 9 for adjustment height and tension cam 10.
