DESCRIPTION

Drawer with an adjustment mechanism

The present invention relates to a drawer with an adjustment device with a housing and with a piece, which is movably supported on it, on whose part a recess and a rotating element have been arranged, which rotates displaces the enclosure with respect to rotation. to the piece.

There are different adjustment mechanisms for furniture. From document DE 77 19 324 a drawer is known, in which a base plate with an eccentric disk has been fixed on a side plate. The eccentric disk rotatably supported can act, in this case, on an angular piece, which has been fixed on the front panel. Therefore, the position of the front panel with respect to the side wall can be modified, especially to align the front panel with a front face of the furniture. Such an adjustment mechanism is comparatively expensive in its assembly, since the base plate and the angular piece must be fixed to the side wall or to the front panel and then an appropriate adjustment for alignment must be practiced. An eccentric adjustment has the disadvantage that the adjustment travel varies greatly and not linearly with respect to the angle of rotation, which results in an irregular adjustment in the case of homogeneous rotation. In addition, the active lever arm is modified and the maximum adjustment travel is limited.

EP 1 203 861 discloses a furniture hinge with an adjustment mechanism, which has an eccentric disc.

It is, therefore, the mission of the present invention to create a drawer with an adjustment mechanism, which with a simple construction allows easy assembly and precise adjustment.

That mission is accomplished with a drawer with an adjustment mechanism with the characteristics of claim 1.

According to the invention, the rotating element has two operating discs, which act respectively on a contact surface of the recess. The contact surfaces are also arranged, in the direction of adjustment, on opposite sides of the recess so that the maximum adjustment is very large, since a driving disc for a displacement is only suitable in one direction. Each maneuvering disc acts only on a contact surface in the recess and, on the opposite side, the respective maneuver disc is arranged at a distance from a side wall in the recess.

According to a preferred configuration of the adjustment mechanism, the operating discs have been configured so that the rotation angle and the travel path are substantially proportional throughout the adjustment travel. Unlike in an eccentric, the geometry of the maneuvering disc can be chosen so that a modification of the angle, when rotating the rotating element, ensures a proportional displacement. Preferably, the rotating element for moving the housing can rotate a rotation angle of more than 180 °, preferably more than 210 °. Rotation angles of more than 240 ° can also be made, for example, up to almost 360 °, so that a larger angular area can be used for the movement of movement.

It is further advantageous that the rotating element present in the adjustment mechanism has a rotation axis, in which the active lever arm for adjusting the housing is substantially constant. In addition, the maneuvering discs can respectively have an outer contact surface in the form of an evolver, which extends around a primitive circle. With this, an active lever arm is kept constant so that, when adjusted, the forces remain approximately equal. The two operating discs can also be symmetrically configured in a base position with respect to a central plane perpendicular to the adjustment direction. According to the first configuration of the invention, the recess is disposed on the piece movably supported to achieve a compact construction. Then, the rotating element is rotatably supported on the housing in at least one stump. In addition, the housing can have a housing to receive a movable supported terminal section, so that the terminal section is not visible from the outside.

According to the other configuration of the invention, the recess has been made in the housing and the rotary element has been rotatably supported on at least one stump in the displaceably supported piece, so that only a circular hole is to be provided in the piece as bearing bushing.

The adjustment mechanism has been configured as a multi-piece tablet, which is adjustable in length to adjust the inclination of the front panel and has at least two mutually driven parts. Therefore, the adjustment of the front panel can take place easily, provided that only the length of the tablet is adapted properly. This can be applied, especially for drawers, in which the longitudinal modification of

the tablet gives rise to another position of the front panel in the upper area distanced from a bottom. The adjustment mechanism is then mounted simply with few components.

According to the invention, the carcass wraps a slat-shaped piece, which is movable in the carcass. This enables stable linear driving in the adjustment direction, providing support in different directions perpendicular to the adjustment direction.

The invention will be explained in more detail below on the basis of an exemplary embodiment in relation to the attached drawings. The figures show it:

several views of one more embodiment of an adjustment mechanism.

A drawer 1 comprises a bottom 2, which is connected on one side with a front panel 3 and with a rear wall 4 on the opposite side. Between the front panel 3 and the rear wall 4, a tablet has been assembled, which forms an adjustment mechanism and has a strip-shaped piece 5 and a sheath-shaped housing 6. In the housing 6 a rotating element 7 is provided to adjust the length of the tablet. Below the tablet, a side wall 8 is mounted at the bottom 2 between the rear wall 4 and the front panel 3. By varying the length of the tablet, the inclination of the front panel 3 can be modified.

As can be seen in Figures 3A and 3B, the slat-shaped part 5 has a rectangular cross-section and can be inserted into a suitable hole in the sheath-shaped housing 6 and can be displaced therein. To this end, a rotating element 7 is provided, which fits into a recess 9 of the slat-shaped element 5. The ribbon-shaped element 5 has been configured, in this case, as a hollow profile so that two adjacent side walls 10 and 11 are provided, which form contact surfaces 21 and 20 in the recess area 9.

To support the rotating element 7, holes are provided in the housing 6, a larger circular hole 12 and a small circular hole 13 being provided on the opposite wall of the housing 6. The small hole 13 serves to receive a stump 14 of the element 7 rotary and forms a rotation axis. The large hole 12 forms a bearing surface for a disk 17 of the rotating element 7 so that the latter is rotatably supported on the housing

6. The rotating element 7 also has a maneuvering disc 15 and a second maneuvering disc 16, the maneuvering disc 15 resting evenly on the wall 11 and the maneuvering disc 16, on the wall 10 of the recess.

In Figures 4A and 4B, the rotating element 7 is shown in the mounted position. The maneuvering disc 15 rests on the left side of the recess 9 on a contact surface 20, while the maneuvering disc 16 rests attached to the wall 10 on the right side of the recess 9 on the bearing surface 21. With this, rotating the rotating element 7 by means of a tool is the length of the tablet discretionally shortened or prolonged, where the maneuvering disc 15 deals with a movement of the housing 6 to the right and the maneuvering disc 16, of a movement of the housing 6 to the left, depending on the direction in which the rotating element 7 is rotated.

In figure 5A, the rotating element 7 is shown in a position, in which the maneuvering disc 15 is attached to a linear contact surface 20 of the wall 11 of the slat-shaped part 5 and, on the opposite side , a contact surface 21 has also been linearly configured and precisely between the operating disc 16 and the wall 10 of the slat-shaped element 5. The operating discs 15 and 16 have also been symmetrically configured with respect to a central plane, which extends perpendicularly through the axis of rotation of the rotating element 7. In addition, the maneuvering discs 15 and 16 have been configured with their outer contour as evolvents, which act on two opposite parallel contact surfaces 10, 21 of the recess 9 and, thereby, ensure a linear adjustment of the tablet.

The operating discs 15,16 have been further configured in such a way that the contact surfaces of the operating discs always rest either with all the angles of rotation on the contact surfaces of the recess of the strip-shaped piece, or always fit with the contact surfaces of the recess.

In Fig. 5B, the rotating element 7 has been turned counterclockwise, where the maneuvering disc 15 is always attached to the supporting surface 20, by the way the housing 6 is slightly shifted to the right . If the operating disc 15 is still rotated, the position shown in Figure 5C is reached, in which the housing 6 moved somewhat further to the right and the ribbon-shaped element 5 was removed from the housing 6. With this , the tablet is prolonged.

Figure 5D shows a position in which the rotating element 7 was rotated, starting from the position of Figure 5A, clockwise to shorten the tablet. With this, press the operating disc 16 against the linear contact surface 21 and press the housing 6 to the left. In the operating disc 15 a stop 23 has been configured, which rests against a contact surface 22 in the recess 9. With this, the maximum rotation path of the rotating element 7 is limited. Similarly, the rotation path of the rotating element 7 is also limited in the opposite direction by means of a stop on the operating disc 16.

In the exemplary embodiments shown, the strip-shaped part 5 and the housing 6 can be made of plastic and / or metal and conduct them mutually substantially in a positively shaped connection. The rotary element 7 can be made of one or more pieces and is also composed of plastic or metal. The rotary element 7 also rests on opposite sides substantially in positive connection so that the recess 9 is formed, so that a precise adjustment is possible.

The slat-shaped part 5 has been configured, in this case, as a hollow profile. Naturally, it is also possible to provide a solid profile, where then the recess 9 can be conveniently configured stepwise. In addition, the strip-shaped part 5 and the housing of the housing 6 can also have a different contour of the rectangular cross-section. The tablet 5 can also have a circular, oval or any other cross-sectional shape. The housing 6 and the piece 5 in the form of a strip can be glued, screwed or mounted by any other means of fixing with the front panel 3 or with the rear wall 4. In addition, the housing can be discretionally fixed to the front panel 3 or to the rear wall 4.

In figures 6A to 6D, another embodiment of an adjustment mechanism in a 1 'drawer is shown. The adjustment mechanism is arranged between a front panel 3 and a rear wall 4. On the front panel 3 a housing 6 ’has been fixed, on which a piece 5’ with a strip shape is movable. For this, a rotating 7 ’element is planned.

The rotating element 7 'has, as in the previous embodiment, a first operating disc 15 and a second operating disc 16, where the operating disc 15 is in contact with a first wall 11 and the operating disc 16, with a second wall 10 of the recess 9 ', as shown in Figures 4B and 5A to 5D, where the recess 9' has not been configured in the mobile part 5 ', but in the housing 6'. The rotating element 7 ′ also has an outstanding stump 14, which is rotatably supported by a circular hole 13 ’of the mobile part 5’.

In housing 6 ’, a housing 18’ is provided in the form of a groove for inserting a terminal section of the piece 5 ’supported in a movable way, so that it is disposed in a protected manner in the housing 18’. By rotating the rotating element 7 ’, the movable part 5’ moves relative to the housing 6 ’, where the rotating element 7’ moves together with the 5 ’part. For this, a housing 28 has been configured in the housing 6 ’, in which a disk-shaped head of the rotating element 7’ is received. The housing 28 can be closed by means of a cover 25 in which a hooking fingernails 26 have been formed. The crimping tabs 26 can be inserted into corresponding crimp housings 17 of the housing 6 ’. As a result, the rotating element 7 ’of the adjustment mechanism has been arranged not visible from the outside, since the stump 14 is coated on the opposite side of the housing 6`.

The 5 ’movable piece can be made, for example, of glass. Other materials such as wood or plastic can also be used.
