Description

The present invention relates to a drawer according to the preamble of claim 1, as well as a method for releasably fixing a front panel to a side frame of a drawer.

The WO 2012/171047 A1 discloses a furniture fitting for attaching a front panel to a drawer frame, in which a plurality of connecting elements lying one above the other are fixed on the front panel. Each connecting element can be coupled to a respective safety gear, which are connected via a transmission mechanism, whereby a common unlocking of the connected safety gears is achieved. The transmission mechanism for unlocking results in a comparatively complicated structure.

The WO 2010/136228 A1 discloses a device for fastening a front panel to a side frame of a drawer, in which the front panel can be pushed into a mechanism on the side frame via a panel support in the insertion direction. The mechanism comprises two floating tong-like legs.

It is therefore the object of the present invention to provide a drawer with a device for releasably fixing a front panel to a side frame of a drawer, as well as a corresponding method for assembling and dismantling a front panel that ensures reliable fixation with simple means and enables dismantling.

This object is achieved with a drawer with the features of claim 1 and a method with the features of claim 10.

The drawer according to the invention comprises a device with a bolt pretensioned by an energy storage mechanism, which can be brought into engagement with a holder that can be joined or plugged in one assembly direction, the holder being supported by a counter bearing, the counter bearing being movable into an unlocking position, and the holder with the front panel can be moved in a direction deviating from the mounting direction for an unlocking process. This allows the front panel to be a first Distance is moved deviating from the mounting direction, preferably transversely to the mounting direction of the front panel, so that only then, in a second distance, the front panel can be removed in the opening direction, i.e. against the mounting direction. As a result, the front panel can only be removed when it is ensured that the front panel has been unlocked and moved accordingly on the opposite side frames of a drawer. In this way, incorrect operations can be avoided.

According to the invention, after unlocking, the front panel can be moved a first distance transversely to the mounting direction of the front panel and a second distance opposite to the mounting direction. In this case, the counter bearing supporting the holder can be moved by the unlocking element, and the holder can be moved in the direction of the counter bearing after leaving the bearing point of the counter bearing on the holder. If only the counter bearing is moved by the unlocking element, several holders with several latches assigned to the holders can be used to lock the front panel on the side frame, with only one counter bearing being required and the counter bearing being moved for unlocking so that no decoupling at each individual holder must take place.

After unlocking, the front panel is preferably lowered down to then be removed in the opening direction. It is also possible to move the front panel in a different direction, but moving the front panel downwards when the drawer is open is easy.

For stable locking of the front panel, a receptacle for a locking bolt arranged on the bolt is formed on the holder. In each case one holder is assigned to a bolt, and a clamping connection can be established between the holder and bolt when locking.

For simple assembly, a run-on bevel can be formed on each holder, which ensures that the bolt swivels when the locking bolt strikes the run-on bevel. A receptacle with a clamping bevel inclined in the opposite direction for clamping the front panel to the side frame can be provided behind the run-up bevel. Tolerance compensation can be carried out via the inclined clamping bevel, since it is immaterial for the purposes of locking at which point the inclined one Clamping slope a clamping of the locking bolt takes place. For easy dismantling, a channel is formed on the holder into which the counter bearing can be inserted when unlocking has taken place and the front panel has been moved accordingly, in order to then be removed against the mounting direction. At least two holders are fixed on one side of the front panel, each of which can be brought into engagement with a bolt, so that high front panels can also be fixed in a stable manner.

According to the invention, a drawer with a device for detachably fixing a front panel on a side frame of a drawer is provided, with a corresponding device preferably being provided on opposite sides. For a stable attachment of high front panels, two holders and two latches are provided on each side of the drawer, which are supported on each side by a counter bearing on a guide.

For a visually appealing design of the drawer, the unlocking element can be actuated via a grip element that is accessible on the underside of the side frame, that is in an area that is only poorly visible.

In the method according to the invention, a front panel with at least one holder on opposite sides is first pushed onto a side frame of a drawer in an assembly direction, each holder being locked to a locking device and the front panel being clamped to a side frame. For dismantling, an unlocking element is then actuated in order to release the locking device from the holder. The front panel can then be moved a first distance transversely to the mounting direction in order to then be removed in the direction opposite to the mounting direction in a second distance. This combined movement of the front panel during dismantling allows the effective direction of the locking mechanism to be optimally adapted to the requirements.

The Figure 1 shows a piece of furniture 1 with a furniture body 2 on which several drawers 3 arranged one above the other are slidably mounted. Each drawer 3 has a front panel 4 which is arranged on opposite sides of a respective side frame 5.

As in the Figures 2A and 2 B is shown, instead of a low front panel 4 with a low height, the drawer 3 can also have a front panel 4 'with a greater height, on which several holders 8, here two each, are fixed on opposite sides. The holders 8 can be pushed into a cavity on the side frames 5 in order to be fixed there on a locking mechanism. As a result, the front panel 4 'can be held on the side frames 5 in a clamping manner. The side frames 5 are connected to one another via a base 7 and at the rear via a rear wall 6.

In Figure 3 the locking mechanism for releasably fixing the front panel 4 to the side frame 5 of a drawer, which is arranged in the cavity of the side frame, is shown prior to assembly with the front panel. The front panel 4 with the two holders 8 fixed on each side are therefore still shown at a distance from the side frame 5. In each side frame 5 there is a mounting plate 9 which can be produced by an angled metal sheet on which two bolts 10 are pivotably mounted. For this purpose, each bolt 10 is held pivotably on the mounting plate 9 via an axis 11. A bolt 10 is assigned to each holder 8. In the exemplary embodiment, the latches 10 are designed as rotatably mounted levers, but it is also possible to use latches that can be moved along a guide, in particular a curved guide.

Each bolt 10 is pretensioned via an energy storage device in the form of a spring 12, in particular a compression spring, and rests on a respective projection 16, 16 'which limits the pivoting movement in the clockwise direction. For this purpose, the spring 12 is supported on one side on a support element 13 which is fixed on the mounting plate 9. A guide element is passed through the spring 12 and the support element 13, and the spring 12 is arranged via the guide element with one end 14 in a central region on the bolt 10. The bolt 10 is angled and has a locking bolt 15 at an end remote from the axis 11, which can come into engagement with the holder 8. The two bars 10 can be constructed identically, the same components being provided with the same reference numerals. Instead of two bolts 10, only one bolt 10 can be pivotably mounted on the mounting plate 9, or more than two bolts 10 can be pivotably mounted on the mounting plate 9. Likewise, the number of holders 8 can be selected accordingly.

For the assembly of the front panel 4, it is first moved towards the side frames 5 in the longitudinal direction, a guide surface 84 of the lower holder 8 resting on a counter bearing 20, as shown in FIG Figure 4 is shown. By shifting on the counter bearing 20 in the longitudinal direction of the side frames 5, the holders 8 come into contact with the locking bolts 15 of the two latches 10 with an upwardly sloping run-up bevel 81 the run-up slope 81 moves, whereby the bolt 10 pivot counterclockwise and against the force of the springs 12.

In Figure 5 The locking bolts 15 are almost at the top of the run-up bevel 81 just before the front panel 4 is fixed to the side frames 5. The springs 12 are tensioned, and by moving the front panel 4 further in the direction of the side frames 5, the locking bolts 15 come into contact with a clamping slope 83 inclined in the opposite direction into a receptacle 82 on the holder 8, the front panel 4 coming to rest on the end face of the side frame 5. A further movement in the direction of the side frame 5 is now no longer possible and movement against the assembly direction is also not possible due to the locking bolts 15 resting against the inclined clamping bevel 83 via the spring force. The inclined clamping slope 83 is oriented at an angle to the vertical, preferably at an angle between 10 ° and 40 °.

In Figure 6 the locked position is shown. Both latches 10 are pivoted clockwise again after the highest point of the run-up bevel 81 has been exceeded, and the locking bolt 15 is located on the inclined clamping bevel 83 and, due to the force of the springs 12, pushes the holder 8 downwards and towards the side frame 5. The front panel 4 cannot, however, be moved downwards, since a counter bearing 20 in the form of a bolt rests on a lower guide surface 84 of the lower holder 8. As a result, the inclined clamping slope 83 causes only a tightening of the front panel 4 in the direction of the side frame 5 and thus a clamping fixation of the same. The position of the locking bolt 15 on the respective inclined clamping bevel 83 is not relevant for fixing the front panel 4, so that assembly tolerances of the holder 8, the front panel 4 or the mounting plate 9 can also be compensated for.

If the front panel 4 is to be removed from the side frames 5 again, an unlocking element 17 in the form of a lever is provided, which protrudes downward from the mounting plate 9 with a handle section 19 and is accessible from below in the side frame 5. The unlocking element 17 is mounted on a bar 21 so as to be pivotable about an axis 18. The bar 21 on which the counter bearing 20 is arranged is mounted on a guide on the mounting plate 9 so as to be linearly displaceable. The guide is through a slot 87 in which the counter bearing 20 is guided and an elongated hole 88, shown in FIG Figure 12 , in which the axis 18 is guided, formed. Other guide means for the bar 21 can also be provided.

On the side opposite to the handle section 19, the projection 16, already described above, is formed on the mounting plate 9, on which the unlocking element 17 is supported. Furthermore, the unlocking element 17 is preloaded into the locked position by a spring 23, the spring 23 being held at one end on the displaceable strip 21 and on the opposite side on the fixed mounting plate 9.

If the unlocking element 17 is now activated by moving the handle section 19 in Figure 6 moved to the right, the bar 21 also reaches the right through the connection via the axis 18, since the unlocking element 17 is supported on the projection 16. This movement takes place against the force of the spring 23.

Such a movement causes the counter bearing 20 in the form of a bolt to move to the right relative to the guide surface 84 until it enters an opening 85 on the holder 8. This position is in Figure 7 shown. Since only the bar 21 is displaced with the counter bearing 20, the two locking bolts 15 remain in spring-loaded contact on the inclined clamping bevels 83. In this position, however, the front panel 4 with the holders 8 can be moved downwards, since the counter bearing 20 is no longer supported on the lower guide surface 84, but is located in the area of the opening 85.

In Figure 8 the position is shown when the front panel 4 is lowered a first distance after unlocking, so that the counter bearing 20 is no longer arranged below the guide surface 84, but within the holder 8. As a result of this downward movement of the front panel 4, the two holders 8 also move downward. When the holder 8 is moved downwards, the latches 10 continue to pivot in a clockwise direction until the projections 16, 16 'limit the pivoting, so that when the holder 8 is moved further downwards, the locking bolt 15 of each latch 10 out of contact with the corresponding clamping bevel 83 . The holders 8 are now moved downward so far that the locking bolt 15 of each bolt 10 is positioned above the highest point of the run-on bevel 81. The guide surface 84 on the lowermost holder 8 rests on a guide track 90 on the mounting plate 9. In this position, the front panel 4 can now be removed against the assembly direction, i.e. in the opening direction of the drawer, as shown in FIG Figure 9 is shown. The bevels 81 are moved past under the locking bolts 15 without contact, and thus the holders 8 disengage from the bolts 10. The counter bearing 20 is returned in a channel within the holder 8 by the force of the spring 23, which leads to the side frame 5 is open. For example, the channel can have a slot 86 for leading through the strip 21 with the counter bearing 20 and otherwise be designed to be closed.

In Figure 10 the completely dismantled position of the front panel 4 is shown. The two holders 8 are arranged at a distance from the side frame 5, and the front panel 4 is raised so far for a new assembly process that the lower holder can be inserted again between the counter bearing 20 and the locking bolt 15 of the lower bolt 10.

In the Figures 11 to 14 the device for fixing the front panel 4 without side frame 5 and without front panel 4 is shown. The holders 8 are essentially angular and have two mutually spaced, parallel legs with inclined run-up bevels 81 and then two clamping bevels 83 also spaced apart but inclined in the opposite direction, between which a section of the bolt 10 can be inserted. The locking bolt 15 passes through the bolt 10 and protrudes on opposite sides, so that the locking bolt 15 on the holder 8 is guided with both protruding ends on the two bevels 81 and then on the two clamping bevels 83 on both sides, thereby preventing tilting.

The counter bearing 20 protrudes from the bar 21 on opposite sides, and the bar 21 can be moved through a slot 86 arranged on the underside of the holder 8, the counter bearing 20 resting on lower webs which form a guide surface 84. By guiding the counter bearing 20 in a slot, the bar 21 can only be moved relative to the holder 8 parallel to the longitudinal direction of the side frame 5.

In Figure 13 a slot 86 can be seen on the underside of the upper holder 8, which is laterally surrounded by guide surfaces 84. It can also be seen that the unlocking element 17 is supported on the projection 16 and, by pivoting the unlocking element 17 against the force of the spring 23, the bar 21 is shifted to the right by the connection via the axis 18.

The locking mechanism on the mounting plate 9 can be built into the side frame 5 as a preassembled unit. Other mechanisms for coupling the bolt 10 to a holder 8 can also be used on the locking mechanism. The movement of the counter bearing 20 by the unlocking element 17 can also be implemented by other mechanisms.
