Mounting bracket for drawer front panels

The invention relates to a fitting for detachably holding the front panel of a drawer, on the side walls of which there is a fitting part to be fastened to the inner surface of the front panel for each side wall and a fitting part to be fastened to or in the drawer side wall, wherein each front panel-side fitting part has at least one locking element with locking edges which can be locked in the drawer-side fitting part.

Today, drawers are predominantly provided with front panels on their visible front side, which protrude beyond the actual drawer box in terms of height and width and thus, when fully inserted into the corresponding furniture carcass, rest on the front surfaces of the carcass walls at the sides and, in the case of the top and bottom drawers of a drawer cabinet, also with the protruding upper and lower edge areas.

This creates the problem that the front panels are

Front panel height direction or adjacent drawers to the side and/or the cabinet side walls or adjacent door leaves must be aligned so that they have an aesthetically pleasing exact alignment when closed. As long as the front panels were placed on the actual drawer front wall and screwed to it, such alignment was relatively easy by dimensioning the hole for the fastening screws screwed into the drawer front wall from the inside of the drawer to be larger than the shaft diameter of the fastening screws, so that the front panel could be moved in all directions within the frame specified by the excess of the holes when the fastening screws were loosened. The front panels were then fixed to the drawer front wall by tightening the fastening screws after alignment.

In recent times, however, drawers are increasingly being manufactured without a fixed front wall, i.e. the front panels also represent the front wall and must therefore be rigidly connected to the drawer box in order to stabilize the drawer in its front area. On the other hand, the alignment described must still be possible.

For drawers with side walls made of plastic or metal hollow chamber profiles, which have recently been used for certain applications, fastening fittings for front panels have been developed inside the side wall hollow profiles (DE 195 31 698 Al), in which a holding part can be attached to the front panel, which can be inserted into a receiving part that can be adjusted and fastened in the hollow space of the side walls and can be locked there. For this purpose, an elongated tab-like attachment protruding from the side of the holding part facing away from the front panel can be inserted into the receiving part and is held in place by a spring loaded between two stationary

A locking element that can be pivoted into the two stable end positions can be releasably locked in the holding part. To release the holding part from the receiving part and thus the front panel from the drawer, the locking element is pivoted into one of the two stable end positions using a Phillips screwdriver. The front panel can therefore only be released using a tool. The same applies to the precise adjustment of the front panel relative to the drawer.

In contrast, the invention is based on the object of creating a mounting fitting for front panels of drawers, which enables automatic locking of the two fitting parts, and in which the locking and releasing as well as the adjustment of the front panel relative to the drawer is possible without tools.

Starting from a fitting of the type mentioned at the outset, this object is achieved according to the invention in that each drawer-side fitting part has a pair of pliers with two arms which are pivotably coupled to one another and spring-loaded into a pivoting end position, on the end sections of which facing the front panel a locking pawl is formed; that each locking pawl has a locking edge facing away from the front panel and a limiting edge facing the front panel, protruding into the assembly path of the locking element and running obliquely to the assembly direction, against which the locking edges of the locking element move when the fitting parts are brought together and the pliers arms pivot against the spring preload until the respective locking edge engages behind the respective locking edge, whereby the front panel-side fitting part is locked to the drawer-side fitting part and thus the front panel is locked to the drawer; and that a handle is provided on each pliers arm which allows the pliers arms to be pivoted manually against the spring preload in order to unlock the fitting part on the front panel

and thus detach the front panel from the drawer side walls.

The unlocking is not done by using a tool, but by grasping the handles with your hand.

To prevent the front panel from accidentally coming off the drawer if the front panel is pulled, or if the drawer is closed with force and the front panel hits the cabinet body with a bang, for example, the inclination of the locking edge relative to the mounting direction should be selected in such a way that self-locking occurs between the locking edges of the locking element or elements and the locking edges when the front panel of the drawer is pulled.

A particularly simple embodiment of the fitting part on the front panel side provides that the locking edges of the respective locking element are each formed on a cross pin arranged parallel to the front panel and at right angles to the locking and limiting edge.

In an advantageous development of the invention, the pliers arms are designed in the manner of the arms of a pair of scissors that cross in the area of the pivotable coupling and open due to the spring preload. The locking pawls protrude from the pliers arms in the direction of the opening movement caused by the bolt preload. This makes it possible to arrange the coupling in relative spatial proximity to the locking pawls, which stabilizes them in the movement sequences.

Further stabilization of the locking pawls and the pliers arms during the loading and unloading required

movements is achieved by holding the pliers arms in an inner housing which has two parallel plate-shaped walls, the distance between which decreases in the area of the locking pawls. 5

A relative fine adjustment of the front panel relative to the drawer parallel to the bottom of the drawer can be achieved by adjusting the inner housing to the drawer parallel to the bottom of the drawer.

This is preferably achieved in that the inner housing is arranged in an outer housing which has a plate-shaped wall parallel to the walls of the inner housing. In the parallel plate-shaped walls of the inner and outer housing, aligned bores are provided through which a horizontal pin rotatably mounted in the outer housing passes. At least one of the aligned bores of the inner housing is designed as a threaded bore. Finally, the horizontal pin has a section with a complementary external thread.

A particularly simple mechanical design is achieved if the pliers arms each have a hole through which the horizontal pin passes. This then forms the pivot axis of the pliers arms. A separate mechanical design of a pivot axis for the pliers arms using another horizontal pin is then no longer necessary.

The spring preload acting on the pliers arms can be easily achieved by forming projections on the opposite end sections of the pliers arms facing away from the front panel, which point towards each other. The ends of a preloaded compression spring can then be held by these projections. The spring pushes the pliers arms and thus the locking pawls apart. To unlock the fittings, the

Compression spring compressed by operating the handles by hand.

To ensure that the handles are easily accessible from outside the inner housing, the handles are provided on the end section of the associated pliers arms facing away from the front panel. They reach through circular openings in a wall of the inner housing. The radius measured from the center of the holes provided in the parallel walls of the inner housing for the horizontal pin to the openings is equal to the distance measured from the center of the holes in the pliers arms to the handles. As a result, when the compression spring is compressed, the handles describe a path that is precisely defined by the openings.

In order to achieve greater stability of the inner housing, the parallel plate-shaped walls of the inner housing are connected to each other at their bottom and top by transverse walls. The same applies to the outer housing, which has a transverse wall connected to the plate-shaped wall at the bottom and top.

These upper and lower cross walls of the inner and outer housings also offer the possibility of holding the inner housing in the outer housing in a vertical direction. For this purpose, the inner housing is held in the outer housing by a vertical pin passing through aligned holes in the upper and lower cross walls of the inner and outer housings.

In addition to adjusting the front panel relative to the drawer parallel to its bottom, the front panel should also be height-adjustable at right angles to the bottom of the drawer. For this purpose, the vertical pin has a thread at least in its middle section. On this threaded section

an actuating element with a complementary internal thread is provided. This penetrates at least one cutout in a plate-shaped wall of the inner housing that is accessible from the outside, which allows it to be rotated from the outside. At least one edge of the cutout in the plate-shaped wall of the inner housing rests against the actuating element. In addition, the hole in the plate-shaped wall of the outer housing through which the horizontal pin passes must be designed as a vertically extending slot. As a result, the inner housing is mounted in the outer housing so that its height can be adjusted by rotating the actuating element at right angles to the bottom of the drawer.

To ensure that the height adjustment of the inner housing is as free from play as possible, the second plate-shaped wall of the inner housing also has a cutout through which the actuating element passes. Ideally, the edge of the cutout of the second plate-shaped wall that is diametrically opposite the edge of the cutout of the first plate-shaped wall that is in contact with the actuating element in the vertical direction is in contact with the actuating element. This limits the play of the height adjustment both upwards and downwards, thus providing a guide for the height adjustment along the vertical pin that is essentially free from play.

In order to further improve the accuracy of the guide, the cutouts each have a tab bent inwards on the edge adjacent to the actuating element, parallel to the actuating element and adjacent to it. The bent tab also ensures that the actuating element does not come into rubbing contact with the sharp edges of the cutout.

The accuracy of the guide for height adjustment can be further improved and tilting of the inner housing in the vertical direction can be avoided, in-

·

in which the respective tabs partially enclose the vertical pin.

The mounting fitting for drawer front panels shown in Fig. IA consists of two fitting parts that can be locked together, namely a fitting part 32 that can be attached to the inner surface of a front panel 30 - only indicated by a dot-dash line in the drawing - and a fitting part 36 that can be mounted in a side wall 34 of a drawer - also only shown by a dot-dash line.

During assembly, the front panel-side fitting part 32 and the drawer-side fitting part 36 are moved towards each other in a direction perpendicular to the plane of the front panel 30 and locked together in a manner described below.

The front panel-side fitting part 32 shown in Fig. 2 consists in the currently preferred embodiment of a U-shaped bent profile with two side walls 38 and a bottom wall 40. The bottom wall 40 can be secured to the inside of the front panel 30 by fastening screws (not shown) that can be screwed into the front panel 30 and pass through fastening holes 41, or by expansion pins (also not shown) that can be inserted into associated blind holes in the front panel 30 and secured there by increasing the diameter.

Furthermore, the front panel-side fitting part 32 has two cross pins 42, which are arranged on the drawer side at a distance from the front panel 30 in the front panel-side fitting part 32. The cross pins 42 are arranged under a predetermined

The two mounting elements 31, 32 are arranged symmetrically in the side walls 38 of the front panel-side fitting part 32 at a predetermined distance from one another in relation to the front panel-side fitting part 32.

As can be seen in Fig. 1A, the cross pins 42 interact with locking pawls 44 when assembling the two fitting parts. When assembling the front panel on the drawer, the cross pins 42 move in the assembly direction against the limiting edges 4G of the locking pawls 44. The locking pawls are formed on the clamp arms 48 shown in Figs. 5 to 10.

The pliers arms 48 each have a bore 50 approximately in the middle. This is held in place by a horizontal pin 52 (Fig.

IB), which thus forms the pivot axis of the tongs arms 48. The tongs arms 48 are pivotably mounted in an inner housing 54 (Fig. 11-15). This in turn is pivotably mounted in an outer housing 56 (Fig. 16-18). The inner housing 54 has two parallel plate-shaped walls 58. On the inside of the inner housing 54, the outer housing 56 has a plate-shaped wall 60 parallel to the walls 58 of the inner housing 54. The horizontal pin 52 passes through holes 62, 64 which are aligned in the parallel plate-shaped walls 58, 60 of the inner and outer housings 54, 56. It is rotatably mounted in the hole 64 in the outer housing 56. The tongs arms 48 are thus pivotably mounted in the inner housing 54.

In Figures 13 and 15 it can be clearly seen that the distance between the parallel plate-shaped walls 58 of the inner housing 54 is reduced in the end section facing the front panel 30, i.e. in the area of the locking pawls 44. This results in improved guidance of the pliers arms 48 and the locking pawls 44.

The pliers arms 48 cross in the area of the pivotable coupling formed by the horizontal pin 52. They are pre-tensioned by a spring 66 (Fig. 1A) in the opening direction of the pliers. The locking pawls 44 protrude from the pliers arms 48 in the direction of the opening movement caused by the spring pre-tension. Lugs 70 are formed on the opposite end sections 68 of the pliers arms 48 facing away from the front panel. The spring 66 is clamped between the end sections 68 of the pliers arms 48 facing away from the front panel, with its ends held by the lugs 70. It thus presses the pliers arms apart in the opening direction. The locking pawls 44 are accordingly pressed apart.

When the front panel fitting part 32 is moved in the assembly direction, the cross pins 42 engage the limiting edges 46 of the locking pawls 44. The limiting edges 46 extend outwards at approximately 45° when viewed in the assembly direction. The movement of the cross pins 42 therefore causes the locking pawls 44 and thus the clamp arms 48 to be forced towards one another in the direction of their closed position against the pre-tension of the spring 66.

The locking pawls 44 have locking edges 72 on their side facing away from the front panel. If the cross pins 52 exceed the apex of the locking pawls 44 when moving in the assembly direction, the clamp arms 48 are pushed apart again by the tension of the compression spring 66 and snap into place behind the cross pins 42. The locking edges 72 of the locking pawls 44 thereby come into contact with locking edges 74 on the side of the cross pins 42 facing the front panel 30. The inclination of the locking edges 72 with respect to the assembly direction 5 is ensured in such a way that self-locking occurs between the locking edges 74 of the cross pins 42 and the locking edges 72 when the front panel 30 of the drawer is pulled.

Finally, handles 76 are formed on the end sections 68 of the pliers arms 48 facing away from the front panel. By grasping the handles and reducing their distance against the force of the compression spring, the distance between the locking pawls 44 is also reduced. This releases the cross pins 42 from the locking with the locking pawls 44 and the locking of the two fitting parts 32, 34 is released.

In Fig. 11, circular-arc-shaped openings 78 can be seen in the wall 58 of the inner housing 54 on the outside of the drawer. The handles 76 pass through the circular-arc-shaped openings 78, making them accessible for manipulation from the outside.

Furthermore, it can be clearly seen in Figs. 12 and 14 that the parallel plate-shaped walls 51 of the inner housing are connected to one another at their lower and upper sides by transverse walls 80. The entire inner housing can be manufactured by punching out the necessary openings and suitably bending the individual walls, combined with welding the remaining seam.

The outer housing 56, which is to be arranged on or - in the case of drawer side walls formed by hollow profiles - in the hollow interior of the drawer side wall 34, also has a transverse wall 82 on its lower and upper sides which is connected to the plate-shaped wall 60. The lower transverse wall 820 of the outer housing 56 serves in the preferred embodiment for mounting the outer housing 56 on the drawer.

The inner housing 54 is pivotably mounted in the outer housing 56 by a vertical pin 86 passing through aligned holes 84 in the upper and lower transverse walls 80, 82 of the inner and outer housing 54, 56. Overall

The outer housing 56 is thus rigidly connected to the drawer, and the inner housing 54 is pivotably mounted with the outer housing 56 in both the horizontal and vertical directions via the two pins 52, 86. The more precise mechanisms of the horizontal and vertical pivoting or displacement of the inner housing and thus the corresponding adjustment of the front panels relative to the drawer are described below.

In order to achieve a targeted horizontal pivoting of the inner housing 54 in the outer housing 56, as can be seen in Fig. 15, the opening on the inside of the drawer in the aligned bore 62 of the inner housing 54 is designed as a threaded bore. The horizontal pin 52 has a complementary external thread in the associated section. Furthermore, a handle 88 is rigidly attached to the horizontal pin 52. The handle is designed in the form of a disk with a protruding rib 90 leading through its center. By grasping the rib 90 with the hand and turning the disk-shaped handle 88, the inner housing 54 is pivoted in a controlled horizontal direction by the interaction of the threads on the horizontal pin 52 and in the bore 62. This allows the front panel 30 to be adjusted in the horizontal direction relative to the drawer bottom.

In order to achieve a vertical displacement of the inner housing 54 in the outer housing 56, the vertical pin 86 has a thread in its middle section. An actuating element 92 provided with a complementary internal thread is seated on the threaded section of the vertical pin 86. In the preferred embodiment, this is designed in the form of a cylindrical body of low height made of plastic or metal with a ribbing or knurling on its peripheral surface. The actuating element 92 breaks through a cutout 94 in the

parallel plate-shaped walls 58 of the inner housing 54. Furthermore, the actuating element 92 breaks through a cutout 96 in the parallel plate-shaped wall 60 of the outer housing 56. The actuating element 92 can thus be rotated from the outside and adjusted in height on the threaded section of the vertical pin 86.

The cutouts 94 in the parallel plate-shaped walls 58 of the inner housing 54 each have an edge 98, 100 on which a tab 102 is bent. The edges 98 and 100 lie diagonally opposite one another in the vertical direction. The tabs 102 run at right angles to the vertical pin 86 and lie against the actuating element 92. They also partially surround the vertical pin 86. By turning the actuating element 92 by hand, it is moved vertically on the vertical pin 86. The actuating element 92 transfers its movement to the tabs 102, which carry the inner housing 54 along with it. The inner housing 54 can thus be moved vertically with essentially no play.

Within the scope of the inventive concept, numerous modifications and further developments of the described embodiment can be realized.
25

For example, the locking edges 7.4 do not have to be formed on cross pins 42. Rather, they can be formed on locking elements of largely any design, which can be one-piece, for example.

0 The only requirement is that the locking pawls 44 can engage behind the locking edges 74.

The pliers do not have to be designed in the form of scissors with crossing pliers arms 48. It is also possible to use pliers whose arms do not cross and are pivotably coupled to one another in _the end section of their arms facing away from the front panel.

Pins can be held in the parallel plate-shaped walls 58, 60 of the inner and outer housings 54, 56, respectively. A spring and handles for unlocking the fittings can be designed in an analogous manner with associated circular-arc-shaped openings.

A pair of pliers with non-crossing pliers arms can also be provided, which are pivotably coupled to one another in their middle section. A compression spring can be held in the end section facing away from the front panel, which presses the arms of the pliers facing away from the front panel apart. Accordingly, the end sections of the pliers facing the front panel with the locking pawls 44 would be pressed together by the spring preload. The locking edges 74 of the front panel-side fitting part 32 would then not have to move outside the locking pawls 44 in the assembly direction, but between them.
