• reference numeral 1 denotes an adjusting device for lateral or vertical adjustment of furniture parts.
• the adjusting device 1 may be formed, for example, as a height adjustment of a cabinet, but the adjustment 1 can also serve for the lateral alignment of a drawer front panel of a piece of furniture. Since the use of the adjusting device 1 for the most diverse, in furniture making eligible purposes here is of minor importance here, in the drawings, only the basic structure and operation of the respective adjustment device 1 is shown and described below accordingly.
• Essential components of the adjusting device 1 are each a drive part 2 and a bearing part 3.
• the drive part 2 has a substantially cylindrical
• the bearing part 3 is provided with a Aufhahmebohrung 4, in which the cylindrical drive part 2 is inserted.
• the drive part 2 has in the exemplary embodiment according to Figures 1 to 8 on two cam-like guide grooves 5, which are arranged in opposite directions and at one point congruent into one another, which is hereinafter referred to as "switch" and provided with the reference numeral 6 ,
• the guide grooves 5 engage two provided in the reveal of the Aufhahmebohrung 4 cams 7, which are radially offset by 180 ° to each other and thus diametrically opposite each other and are arranged offset in the axial direction of the drive member 2 by the pitch of the guide grooves 5 to each other.
• the cross section of the guide grooves 5 is approximately semicircular in shape and the cross section of the engaging in these guide grooves 5 cam 7 is adapted to the cross section of the guide grooves 5.
• the drive part 2 is provided on at least one end face with a recess, preferably a Wienschlitzaus originallyung 2a, to attach a tool for actuating the drive member 2 can.
• the drive member 2 If the drive member 2 is rotated about its longitudinal axis, this has due to the cam-like design of the guide grooves 5 result that the drive member 2 is displaced relative to the bearing part 3 in the direction of its longitudinal axis and performs a full reversing axial displacement during a complete revolution.
• the drive member 2 is moved in a complete revolution from a given basic position initially maximum in one and then in the reverse direction maximum in a different displacement position, so that after execution of the 360 ° rotation, the original starting position is reached again.
• the maximum adjustment from a certain basic position is thus achieved by rotation of the drive member by 180 °.
• the addressed specific basic position is in each case one of the possible end positions of the drive part 2.
• This interplay takes place after every 180 ° rotation of the drive part 2 and ensures a secure guidance of the drive part 2 both in each direction of rotation as well as with repeated rotation by significantly more than 360 °, whereby it is always ensured that the drive part 2 thereby only by the maximum stroke - in accordance with the pitch of the guide grooves 5 - is axially displaced.
• the drive member 2 is provided in the region of its circumference with two opposing Axialnuten 8, wherein advantageously one of these axial grooves 8 aligned with the switch 6 and the opposite axial groove the switch 6 is arranged diametrically opposite one another.
• the depth of the Axialnuten 8 is slightly smaller than the depth of the guide grooves 5, which is apparent in particular from the sectional view of Figure 5.
• the drive part 2 is arranged on the face side in a component 9 which is to be considered stationary and thus itself can not be displaced axially. This has the consequence that upon rotation of the drive part 2, the bearing part 3 is displaced relative to the drive part 2 in the axial direction.
• This illustrated embodiment can be used for example as a side adjustment for a drawer front panel, in which case the stationary member 9 may be a side frame of a drawer and the bearing part 3 is formed as a component to which a drawer front panel is ultimately attached.
• the exemplary embodiment according to FIGS. 1 to 8 can be further simplified to the effect that the arrangement of two guide grooves 5 is dispensed with and only one such guide groove 5 is provided. Since in this single guide groove 5 then only a cam 7 can engage, the load capacity is somewhat limited in such a simplified embodiment, also theoretically there is at least the risk of tilting of the drive member 2 in its receiving bore 4. In applications with low external load can However, these theoretical discussions are left out of consideration and such a simplified embodiment can be used with advantage.
• FIGS. 1 to 8 with its two guide grooves is to be regarded as advantageous since a relatively flat design can already be achieved, with a flat design meaning only a small thickness of the bearing part 3 and thus the corresponding one other components.
• a higher load capacity and strength and better guidance, but with a greater width of the entire adjustment device 1 is achieved when two completely self-contained and mutually spaced guide grooves 5 are provided, as in the embodiment of the

• the cam 7 may be provided on the drive part 2 (see Figures 11 and 12) and correspondingly the guide grooves within the reveal of the receiving bore 4 of a bearing part 3.
• Such a construction but still requires GroE ßere width of the entire adjustment is thus possibly advantageous if the width of the entire device in a specific application is irrelevant.
• the adjusting device 1 is used as a height adjustment device for a cabinet, that is, when the adjusting device 1 practically forms a height-adjustable base foot for a cabinet furniture.
• a particularly stable embodiment is also achieved when the drive part 2 and / or the receiving bore 4 of the bearing part 3 is equipped with a plurality of guide grooves 7, which are then arranged parallel to each other in such a multiple arrangement. As a result, both the carrying capacity and the security against tilting or tilting of the drive part relative to the bearing bore 4 are increased.
• a corresponding embodiment is indicated in FIGS. 13 and 14.
• an adjusting device 1 according to the invention is reversibly adjustable by continuous rotation in only one direction, for example, with advantage on the drive part 2, a driver 10 may be provided which can be rotated by a corresponding device 11 always by applying pressure or tensile forces in one direction only , what eg may be advantageous in a poorly accessible arrangement of the adjusting device 1 on a piece of furniture.
• An adjustment device according to the invention can thus be adjusted easily and in all directions even in inaccessible places that are not accessible with a commercially available tool.
• the course of the guide groove 5 or the guide grooves 5 it may be useful to choose the course of the guide groove 5 or the guide grooves 5 so that over a comparatively large rotation angle range, a relatively flat increase in the guide groove 5 or the guide grooves 5 is realized, while a comparatively strong over a correspondingly small rotation angle range Fall of the guide groove 5 or the guide grooves 5 is realized in the provision.
• the advantage of such a solution The solution may be that in case of an unwanted exceeding of an adjustment process near the vertex of a guide groove 5 or more guide grooves 5 a quick reset is possible.
• FIGS. 17 and 18 show that an adjusting device 1 according to the invention can also be used to more or less bias a spring 12 acting on a specific component of a piece of furniture.
