  German patent document DE 100 21 033 discloses an adjustment device for a drawer front panel, in which a number of adjustment means are provided in the housing in the form of pinions, levers and toothed racks. Adjustment of the front panel relative to the drawer frame is possible using adjustment means. The adjustment mechanism requires multiple components and is relatively complicated to manufacture.

  German patent document DE 39 30 662 discloses an adjustment device for the front panel of a drawer, in which a screw which can be actuated from the side meshes with a gear wheel, the gear wheel for longitudinal adjustment And a center pin guided in the recess. Such a gear structure allows corresponding adjustments, but is relatively complicated to manufacture and install.

  Finally, U.S. Pat. No. 3,041,657 discloses a furniture fixture for a hanging door in which adjustment capability is provided in the vertical direction. A rotatable curved guide is mounted on the housing, and the curved guide can be used to adjust a holder that is movable on the rail. In the case of such a hanging door, the adjusting device may be locked by the high weight force generated after adjustment, and the mounting part generally requires metal because it requires strength.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a drawer front adjuster having a simple structure and capable of adjusting a front panel with respect to a side frame.

  This object is achieved by a front regulator for drawers having the features of claim 1.

  According to the present invention, the rotatable worm wheel is disposed on the guide that can be fixed to the front panel and the rail that can be fixed to the side frame, and the worm wheel moves the slide along the guide when rotating. Therefore, it is possible to provide an adjustment capability for the drawer front panel which is formed from only a few components and can be easily installed. The front adjuster can be realized with a compact structure and is suitable for use in a narrow space condition.

  For precise adjustment, the worm wheel is engaged with the slide using at least one protrusion. A plurality of protrusions are preferably engaged simultaneously with the worm wheel, so that a particularly good guidance is provided between the worm wheel and the slide.

  According to a preferred structure of the invention, the slide and the guide may be provided in the form of an elongated piece and may be guided relatively accurately with respect to each other by corresponding guide surfaces. Also, the strip-shaped implementation allows for a flat structure and a positive interlock is possible with a corresponding cross-sectional structure. The guide is preferably provided with a U-shaped cross section and surrounds the slide from the side.

  The worm wheel is preferably mounted so that it can rotate within the opening of the guide. In this case, a circular protrusion can be used to insert the worm wheel into the opening, and the worm wheel has a spiral protrusion that is engaged with at least one protrusion of the slide. Therefore, the protrusion can be moved linearly when the worm wheel rotates. The worm wheel can be located in the cavity between the slide and the guide, so that no further holding or supporting means are required. Also, the front adjuster thus formed can be easily removed without breaking.

  It is preferable that the front surface of the guide can be fixed to the front panel by fastening means. The guide can have, for example, at least one opening or one slot, and a screw can be secured to the opening or slot. Other fixations with adhesives or mechanical fasteners are also possible.

  For example, the slide and the guide can be fastened and fixed to each other so that the slide and the guide can be fixed to each other after the adjustment operation. For this purpose, a locking screw can be provided on the slide and / or guide. Other securing elements may be used to avoid unintentional adjustment of the slide and guide.

  According to the invention, a drawer with a corresponding front adjuster is also provided. The front adjuster is preferably installed on the frame mounting portion, and the front panel is rotatably held on the lower portion of the side frame. Since the frame mounting part extends from the rear wall of the drawer to the front panel, the front adjuster can be used to transfer the force directly from the front panel to the rear wall through the frame mounting part. A short distance can be adjusted in the longitudinal direction of the panel. Furthermore, the inclination of the front panel relative to the drawer can be set as a result of the longitudinal adjustment capability.

  The problem is often high, especially when the front panel surfaces are not perfectly flush, but rather the front panels protrude somewhat from each other at the top edge or very close to the body. Occurs in the case of drawers with Tilt adjustment is possible for correction.

  Hereinafter, the present invention will be described in more detail based on a plurality of exemplary embodiments with reference to the accompanying drawings.

The perspective view of the installation state of the drawer front adjuster is shown. FIG. 2 shows an exploded perspective view of the front adjuster of FIG. 1. A to C show a view of the front regulator of FIG. 1 without a drawer. A and B show the front adjuster of FIG. 3 in different positions. A to C show views during installation of the front adjuster of FIG. A and B have shown the figure of the front regulator which concerns on deformation | transformation embodiment.

  The drawer front adjuster 1 is installed between the front panel 2 and the side frame 3. The side frame 3 includes a lower portion 30 and a frame attachment portion 31. The front adjuster 1 is installed in the frame attachment portion 31 and enables adjustment in the longitudinal direction of the side frame. Therefore, the front panel 2 can be rotated, and the rotation axis 32 is provided in a region between the lower portion 30 and the front panel 2. The frame attachment portion 31 can be provided as a plate, particularly a glass plate, or as a handrail bar or profile.

  The front panel 2 can be fixed in the region of the pivot axis 32 using a front fastening fixture, and the front fastening fixture may have a vertical adjustment mechanism and a horizontal adjustment mechanism, and a depth. You may have an adjustment means.

  As shown in FIG. 2, the front adjuster 1 comprises a slide 4 positioned so that it can move along a guide 5. The slide 4 and the guide 5 are provided as elongated strips, and may be formed of plastic and / or metal.

  The guide 5 has a circular opening 14 in the floor area, and the worm wheel 6 is rotatably mounted in the opening 14.

  The slide 4 is connected and fixed to the drawer side frame 3 via screws 7, and the screws 7 are guided in sleeves 8 made of plastic, for example, which are inserted into the openings 9 of the side frames 3. The screw 7 is fixed in the screw hole 10 of the slide 4 using a screw portion. Other fastening means may be provided to secure the slide 4 to the side frame 3, for example, the slide 4 can be glued to the mounting portion 31, especially when it is provided as a glass plate.

  At least one screw 11 is provided for securing the guide 5 to the front panel 2 and can be inserted into a slot or opening 13 in the front wall of the guide 5. The screw 11 is screwed into the hole 12 of the front panel 2 using a screw portion.

  As shown in FIG. 3, the strip-shaped guide 5 has a U-shaped cross-section with side walls 15, which have webs 16 facing inward at their ends. Accordingly, the elongated strip-shaped protrusion 17 of the slide 4 is surrounded so that the slide 4 and the guide 5 can be linearly moved in the longitudinal direction in any case.

  In order to adjust the position of the slide 4 with respect to the guide 5, the slide 4 is provided with a projection 19 that can engage with the spiral projection 18 of the worm wheel 6 on the side facing the guide 5. The spiral projection 18 can rotate about the axis formed by the opening 14 and allows the projection 19 and thus the slide 4 to move linearly when the worm wheel 6 rotates. The user can only rotate the worm wheel 6 using the screwdriver 20, in which case the elongated strip-shaped projection 18 can also engage with the plurality of projections 19.

  The position of the front adjuster is shown in FIG. 4A, in which the slide 4 is completely received in the guide 5 (maximum retracted position). The guide 5 is fixed to the front panel via a fastening screw 11, and the worm wheel 6 is rotated to a position where the slide 4 is drawn. In order to adjust the slide 4 and thus the length of the mounting part 31 of the side frame 3, the worm wheel 6 is rotated until it reaches the extended position shown in FIG. 4B. The worm wheel strip-shaped protrusion 18 pushes a specific protrusion 19 in one direction from the guide 5, thereby providing a corresponding adjustment.

  The installation of the front adjuster is shown in detail in FIGS. First, the slide 4 is fastened to the side frame 3, in which case the screw 7 is not yet fully tightened. On the other side, the guide 5 is fixed to the front panel 2 via one or more screws 11, in which case the worm wheel 6 is arranged on the guide 5. Thereafter, the slide 4 is inserted into the guide 5 and the worm wheel 6 is further rotated so that the spiral projection 18 engages one of the projections 19.

  In this pre-fixed position, the front panel 2 can be adjusted with respect to the side frame 3 by the method described above. After the setting, the slide 4 can be fixed to the guide 5 by further screwing the screw 7. The front side of the screw 7 can be moved on the base of the guide 5 for clamping. Alternatively, the screw 7 can be moved relative to the part of the worm wheel 6. Thereby, the slide 4 and the guide 5 are fixed to each other, and an unintended adjustment is avoided.

  5A to 5C, the fixing is performed by pressing the guide 5 against the plate 31 of the frame mounting portion. In this case, the slide 4 tightens the leg portion of the guide 5 against the plate by tightening the screw. In FIG. 5A, a small gap can be seen between the guide 5 and the frame mounting portion 31, and this gap is not shown in FIG.

  An alternative embodiment of the front adjuster in which an additional locking screw 21 is provided on the side of the guide 5 is shown in FIGS. 6A and 6B, where the locking screw 21 can be used to fix the slide 4 and the guide 5 together. it can. The remaining parts are provided in the same way as in the previous exemplary embodiment and are therefore given the same reference numerals. The lock screw 21 is screwed into the screw hole of the guide 5 and can be screwed in with a screwdriver 20 until the lock screw abuts on the slide 4 and the slide is fixed by the clamp.

  In the exemplary embodiment shown, the tilt of the front panel 2 is adjusted by the front adjuster 1. Of course, a front adjuster for vertical adjustment or horizontal adjustment of the front panel 2 can also be used. In particular, of course, the slide 4 can be attached to the front panel 2 and the guide 5 can be attached to the side frame 3. Further, instead of the guide 5, the slide 4 has a circular opening, and a worm wheel can be rotatably mounted on the circular opening.

  Further, for example, when the side frame 3 and / or the front panel 2 is formed from plastic or a bent sheet metal, the slide 4 and the guide 5 may be provided integrally with the side frame 3 or the front panel 2. it can.

  Parts that can be adjusted and held on the front panel 2 such as the frame mounting portion 31 may be formed with a further structure that hides a gap generated during the adjustment between the frame mounting portion 31 and the front panel 2. it can. For this purpose, the frame mounting portion 31 can be pushed into the groove of the front panel 2.

  Instead of having the lower portion 30 and the frame attachment portion 31, the side frame 3 can be provided as an integral part as a side wall.
