Description

Device for the adjustable connection of front panels of pull-out furniture parts with adjustable fittings

The invention relates to a device for the adjustable connection of front panels of pull-out furniture parts with adjustment fittings that are connected to the furniture part and have adjustment means that allow independent adjustment of the front panels to the furniture part in height and side as well as clamping, the brackets consist of interlocking hooks, one of which is adjustable relative to the furniture part by means of a screw in a guide.

Devices of the generic type are known, for example, from DAS 21 23 512.

Further developments of such devices are described in DBGm 77 05 784. One of these further developments relates to a connection between a pull-out furniture part and its front plate, in which a fitting part for fastening is arranged on the inside of the front plate, in which one is inclined inwards upright hook is arranged, which cooperates with a hook on the furniture: arranged obliquely downwards. The obliquely downward hook can be moved in a vertical guide on the furniture part and is raised and lowered by a screw running parallel to the guide for cooperation with the hook standing up at an angle from the front panel, so that an adjustment of the front panel and subsequent tightening of the front panel compared to the furniture part. The set screw can be reached from below.

The invention has set itself the task of further developing and improving such Vorrichtun conditions, so that they are simpler and more economical in construction and application and also easier to handle and more accessible.

To achieve this object, a device of the generic type is characterized in that horizontal guides are arranged near the two side edges in front of the front wall of the furniture part for a hook which is open to the side and to the front and which lies in its effective area in front of the guides and in its The two sliding feet lying on the guides are provided with a thread parallel to the guide for engaging a screw, the head of which is supported on the circumference of an opening in a side wall of the furniture part, and a counter-hook fastened to the rear of the front plate in a horizontal arrangement for engaging behind the first-mentioned hook. A holding projection, which is open vertically to the front and below, is fastened to the front plate, preferably beneath the horizontal hook on the front panel side.

The horizontal guides for the hook on the furniture part side can be arranged directly on the outside of the front wall of the furniture part, but they can also be at a front, front-parallel bend from parallel to the side walls of the furniture part ver running strips, for example as a guide or Stiffening strips serve to be arranged.

The horizontal guides for the sliding foot of the hook are designed as sliding strips with a widened recess in the direction of the front wall of the furniture plate, and the sliding foot has a widening at its base for engaging in these recesses. The sliding foot is advantageously guided both at its widened base and between the closer parts of the guides.

According to an advantageous embodiment, the hooks fastened to the rear of the front plate and the projection are connected to one another by a web. On the hook, the projection or the connecting web, a vertical small rib projecting somewhat towards the furniture part is expediently formed, to which an indentation or a groove is assigned on the immediately opposite, adjacent surface in order to define a zero position in the horizontal direction. A vertical tongue is formed on one of the same parts, the broad end of which is provided with a horizontal rib projecting somewhat towards the furniture part, which is assigned a horizontal edge on the immediately opposite, adjacent surface in order to have a zero position in the vertical direction define.

The screw for adjusting the slide foot is very advantageously guided in the opening in the furniture-fixed side wall in a recessed, internally smooth socket made of metal, and it expediently interacts with a socket made of metal which is inserted into the slide foot and has an internal thread. The two mutually opposing surfaces of the horizontally interacting hooks are expediently provided with a surface roughening, for example a horizontally running reefing.

Due to the opposite hooks in the horizontal direction on the furniture part and the front panel, a very simple attachment of the front panel is made possible according to the invention. It is just necessary to hold the furniture panel against the pull-out furniture part, for example a front panel against the front of a drawer and to slide the movable hook part, which is arranged on the furniture part in guides, to both sides so that the front panel is initially held. It is helpful that the set screw in the guide bushing of the side wall of the furniture part, which is smooth-walled on the inside, can also be moved so that the furniture part-side hooks are pulled against the front panel-side hooks by pulling out the two screws to hold the front side in place.

By screwing the screws into the sliding feet of the hooks on the furniture part side, these can then be adjusted together with the front panel in the lateral direction so that the front panel can be aligned. For tightening, the two side screws are then turned against each other so that both hooks on the furniture side are pulled apart. The particular advantage is also that the front plate is bent slightly inwards in its central part by this bracing, so that you can achieve the entire length of the front plate by this device. This is particularly important if the pull-out furniture parts are kitchen drawers, for example, or drawers in furniture that are used in the medical sector, because they place particularly high demands on cleanliness and hygiene and avoid all possibilities for dirt accumulation.

This simple construction of the connection, setting and fastening of the front panel to the furniture part is supported since, when inserted, a support can be provided downwards by a holding projection on the front panel which is open at the bottom and which overlaps a counter-holder on the furniture part from above . This prevents the front panel, which is loosely attached to the furniture part, from falling down during further handling, adjustment and while tightening the screws and it makes it easier to adjust it horizontally and vertically to align it with other front panels.

The connection of the hook to the projection on the front plate by means of a web simplifies the manufacture of this fitting and also its attachment and the interaction of the two fitting parts.

Further advantages of the invention are listed in the specific description. The invention is explained below using exemplary embodiments with reference to the drawings. In the drawings :, show:

In the illustrated and described embodiments of pull-out furniture parts with adjustment fittings, drawers are described as a preferred application, which are made in one piece from plastic and are designed in such a way that the front panels or, in this case, so-called front panels on the Front are invisibly attached. It results from the fact that the interior of the drawers is completely smooth and smooth, without any recesses or openings in which, for example, dirt could collect and which are difficult to clean. An adjustability of the front panels of the drawers according to the height and to the side is desirable in order to align the fronts of the individual furniture bodies, which stand side by side and one above the other, against each other after the furniture has been installed on a regularly not quite level surface, so that a uniform image is achieved continuous lines.

In the front view of FIG. 1, a drawer is shown schematically, the front panel being indicated by dash-dotted lines and the parts of the front of the drawer located behind it also being indicated for the purpose of determining their position. In particular in conjunction with FIGS. 2 to 4, this is the fitting 2 fastened to the cover 1 on the back and the parts 4, 5 and 6 which cooperate with this fitting 2 on the drawer 3. The part which is stuck to the front cover 1 Fitting 2 consists of an upper hook 7, which is open towards the center of the front and which cooperates with a drawer-fixed hook 8, which is open and open towards the front, and a retaining projection 9, which is open towards the front and down and engages over a counter holder 1o, which is connected to the front wall of the drawer or is arranged in front of it.

The hook 8 connected to the drawer sits on a sliding foot 11 which is horizontally displaceable in a guide consisting of two horizontal guide rails 12 and 13. The sliding foot 11 has on its part closest to the drawer and its front wall up and down projections 14 and 15, which engage recesses 16 and 17 of the same shape on the guide rails 12 and 13 and are displaceable therein. The lateral guidance of the sliding foot 11 is not only effected by these projections 14 and 15, but also mediated by the overlying upper and lower surfaces 18 of the sliding foot 11, which cooperate with corresponding counter surfaces 19 on the guide rails 16 and 17. The hook 8 lies with its lower surface 2o freely above the upper end §1 of the guide rails 21, so that it is freely accessible in its entire cross-section on both sides, that is up and down.

In parallel to the guides 12, 13, a screw 22 is arranged therebetween, which engages in a thread in the sliding foot 11 and is guided in the associated side wall 23 or a corresponding projection from the side wall of the drawer in a socket 24, the head 25 of the Screw is accessible from the side. It can be seen that by means of this screw 22 the sliding foot 11 in the guides 12, 13 and thus the hook 8 in front of the front wall of the drawer is horizontally displaceable. For displacement, both the screw, guided in the smooth bushing 24, pulled out or pushed in, and, in the pressed-in state, can be turned in the thread in the sliding foot 11 by means of a screwdriver on the head 25 of the screw, and thus the sliding foot with the hook can be moved horizontally will.

It should be noted that, according to Figure 1, the arrangement described above with the hooks 7 and 8 is arranged in mirror image on both sides of the front of the drawer, so that the screws 6 or 22 and 25 for adjusting in the same direction as well as for mutually adjusting the drawer connected hook 8 cooperate.

In order to complete the connection of the panel 1 to the drawer 3 and in particular to achieve a secure connection when the panel 1 is attached to the drawer without the risk of the panel falling out downward during the adjustment process to the side and in height , Below the Ilakens 7 on the panel, the lower retaining projection 9 is arranged, which engages behind a holder on the drawer, but one Adjustment movement in vertical and horizontal direction in the areas required here is not restricted. The projection 9 can be provided on its surface 26 cooperating with the counter-holder with a slight slope if it is desired to obtain a special clamping effect in this area.

In Fig. 2 the embodiment of a drawer is shown with the left front corner in perspective view, in which the guide rails 12, 13 are arranged directly on the front wall 3 of the drawer, they can be molded there.

In Fig. 3, another embodiment is shown in a corresponding representation, in which a drawer with double side walls is designed such that in the open from below open space between the spaced side walls, according to FIG. 4, a ribbed strip 27 is inserted. A receiving groove 28 for inserting commercially available drawer guides is formed on this rib strip. Instead of a rib strip 27, a guide strip can also be laterally attached to the drawer. The side bar is provided with a front bend 29 which lies in front of the front wall of the drawer and on which the guide rails 12, 13 for the slide foot 11 of the hook 8 on the drawer side are formed. The assignments and ratios of the individual parts are otherwise in accordance with the embodiment described above.

The function of the device according to the invention is described below: The fitting parts 2 are attached to the drawer panel 1 near the two sides. The hooks 5 are pushed into their innermost position by means of the very ben 6. The front panel 1 we set at an angle and pushed with the projections 9 over the counter holder 1o and pressed against the drawer, that is, pivoted with their ob part against the drawer. Then with Hil dt_r screws 6 the drawer-side hook 5 on both sides pulled outwards in its guides so that these drawer-side hooks lay in front of the hooks 7 of the fitting on the front panel. The front panel is now connected to the drawer without it falling off. To adjust the front panel with respect to the drawer and thus towards the furniture towards the side, the hook parts 8 with their sliding feet 11 in the guides 12, 13 are moved by means of the screws 6 under the action of screwdrivers on the screw heads 25, with the screw on the one side of the drawer is tightened, the other side of the drawer is released. Once the required side alignment has been achieved, the two screws are turned slightly in opposite directions on both sides, so that a certain amount of pre-tension is created by moving the two hooks apart on both sides of the drawer. The opposing surfaces of the hooks 8 and 7 are appropriately roughened, they can be corrugated. In this position, a vertical movement of the panel relative to the drawer is still possible. As well as this vertical adjustment and alignment is done according to the requirements, the setting achieved in each case is maintained due to the friction between the hook surfaces, the screws 6 are tightened in opposite directions on both sides of the drawer, so that the drawer-side hook parts 8 are pressed apart even further . Thus, a firm tensioning of the front panel 1 against the support surfaces on the front of the drawer is achieved, so that the front panel 1 is firmly and immovably connected to the drawer in the set position. The special arrangement of the connecting parts, in particular the hook 5, provides the additional advantage that, owing to the flow of forces, the front panel on the one hand and the drawer front wall bend, albeit slightly, but sufficiently, in the sense that these bends are directed towards one another are in the middle of the front of the drawer, the closest contact between the two parts is reached. This avoids a gap between the attached front panel and the front of the drawer due to bending stresses could.

In order to facilitate the placement of the drawer panel in the desired position, a somewhat projecting, vertical small rib 31 is formed on the front fitting, expediently on the relatively thin connecting web 3o between the upper horizontal hook 7 and the lower holding projection 9 on the inside. On the lower guide bar 13, a notch 32 is formed on the outside. These two molded parts 31 and 32 are arranged in such a way and work together that a zero position of the front panel relative to the drawer is defined in the horizontal direction when inserted. The engagement of the rib 31 in the notch 32 can be clearly felt by moving it horizontally with the hook part 8 retracted far.

Furthermore, a tongue 33 is preferably formed on the connecting web 3o, which, standing vertically, is provided with a slightly projecting horizontal rib 34 at its broad upper end. The arrangement is such that in the vertical zero position of the panel opposite the drawer, this rib 34 on the tongue 33 overlaps the upper edge 35 of the lower guide rail 13, so that when the panel is attached to the drawer, a zero position in vertical direction is defined and because it can be easily adjusted.

The invention is not limited to the illustrated and described exemplary embodiments, for example, the retaining projections 9 can also be attached at a location other than directly below the horizontal hooks 7 on the front panel 1, with a corresponding arrangement of counterholders on the drawer. For example, holding projections of this type can be provided over the entire length of the front wall of the school drawer. It is also not absolutely necessary that the retaining projections sit only below the two horizontal hooks 7 on the panel, they can also be above this in special cases horizontal hooks can be attached to the panel with the appropriate arrangement of counterholders on the front of the drawer. An arrangement of retaining projections above and below the horizontal hooks can also be provided, for example, in the case of particularly tall drawers, the arrangement being made similarly to a sliding door, so that the upper retaining projections with their counterholders are considerably longer than the lower retaining projections, so that when inserting the panel, the upper retaining projections are first engaged, the panel is then pivoted and lowered against the drawer at the bottom, so that the lower retaining projections also overlap the counterholders, but the upper retaining projections do not slide out of their overlapping position, but still in Stay engaged.
