    The present invention relates to an actuator for moving a flap of a furniture, comprising: - at least one pivotally mounted actuating arm for moving the flap, - a spring device for acting on the actuating arm with a pivoting moment in the opening direction, - an adjusting device with an adjusting screw, the Has thread, wherein the acting pivoting moment of the spring device is adjustable to the actuating arm by a rotational movement of the adjusting screw.
    Furthermore, the invention relates to an arrangement with an actuator of the type to be described and with a flap of a piece of furniture, which is movably supported by the actuator between a vertical closed position and an upwardly moved open position.
    An actuator with an actuator arm, a spring acting on the actuator spring device for weight balance of the flap and with an adjustment for adjusting the force acting on the actuator arm pivoting moment is described for example in WO 2006/005086 A1 of the applicant. This actuator comprises a pivotally mounted intermediate lever, which pivots the adjusting arm via a pressure roller and a setting contour, wherein the distance between the point of application of the spring device is adjustable relative to the axis of rotation of the intermediate lever by an adjusting device. The adjusting device may for this purpose comprise a rotatably mounted threaded spindle, wherein the point of application of the spring device relative to the threaded spindle by rotation thereof within predetermined limits is adjustable. However, the adjustment of the spring application point along the threaded spindle is relatively slow, because for a significant adjustment of the spring force corresponding to many revolutions of the threaded spindle are required. In addition, slight adjustments of the spring force are difficult for the person making the adjustment of the spring force to control, and often hardly noticeable,
    Object of the present invention is therefore to propose an actuator of the type mentioned, wherein the adjustment of the spring force is simplified. 69136-21 / hn * * Μ II »*« · »« 2
    This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.
    According to the invention it is thus provided that the adjusting screw has a separate from the thread escapement, which prevents unintentional rotational movement of the adjusting screw.
    By a separate from the thread of the screw escapement adjustment screws or threaded spindles can now be used, which also have a correspondingly high thread pitch compared to a standard thread for the purpose of a high Verstellhubes. However, such high pitch threads (with a pitch two or more times compared to a standard thread) also have low self-locking over a standard thread, and therefore, in accordance with the present invention, an escapement is provided which allows controlled adjustment of the set screw unintentional adjustment of the adjusting screw, however, prevents. Such uncontrolled adjustment is often brought about by the fact that a flap of a piece of furniture, which is connected in the position of use with the actuating arm, repeatedly opened or closed, whereby the adjusting screw is unintentionally rotated. By the proposed inhibiting device such uncontrolled adjustment of the adjusting screw can be largely prevented.
    According to one embodiment of the invention can be provided that the inhibiting device between the adjusting screw and a, preferably fixed to the housing, abutment of the actuator is effective.
    The inhibiting device may comprise surface elements arranged or formed on the adjustment screw, which interact with the abutment of the actuator. These surface elements may be arranged or formed on a screw head, preferably on the underside and / or on a peripheral edge of the adjusting screw. Possible embodiments result from the fact that the surface elements are formed as nubs, grooves, teeth, tips, elevations, depressions and / or as a relief-like structure, which frictionally and / or at least partially form-locking interaction with the intended abutment of the actuator.
    In an alternative embodiment of the invention can be provided that the screw head is acted upon by a mechanical spring element with force, whereby a controlled adjustment of the adjusting screw is possible, an uncontrolled adjustment due to the force acting on the screw head spring force, however, is prevented.
    The inventive arrangement has an actuator of the type in question and a flap of a piece of furniture, which is movably supported by the actuator between a vertical closed position and an upwardly moved open position.
    Further details and advantages of the invention will be explained with reference to the following description of the figures. It shows or show:
    1a, 1b Fig. 2a, 2b Fig. 3a, 3b Fig. 4a-4d Fig. 5a-5d is a perspective view of a piece of furniture with a relatively highly movable flap and an enlarged detail of this, a possible embodiment of an actuator in a perspective View and an enlarged detail of this, a mounted on a lever of the actuator adjustment and an enlarged detail of this, two embodiments of screws in different views, possible embodiments of an inhibiting device for preventing uncontrolled rotational movement of the adjusting screw.
    Fig. 1 shows a furniture 1 with a furniture body 2 and a relative to the furniture body 2 hochbewegbaren flap 4 in a perspective view. On at least one side wall 3 of the furniture 1, an actuator 5 is mounted with a pivotally mounted actuating arm 6 for moving the flap 4. For at least partial weight compensation of the flap 4, a spring device 8 is provided, which acts on the actuating arm 6 with a pivoting moment in the opening direction. In the exemplary embodiment shown, the spring device 8 acts firstly about an adjusting lever 7, which is mounted pivotably about the axis of rotation (P) and which is connected via a transmission mechanism (for example via a lever mechanism and / or via a control contour of the flap 4 influencing the movement behavior of the flap 4). Arrangement) the actuator arm 6 is pivoted.
    FIG. 1 b shows the area circled in FIG. 1 a in an enlarged view, the setting device 20 being shown for setting the pivoting moment acting on the adjusting arm 6. Spring device 8 acts on a nut. (4) which is displaceably mounted along a screw shank 9 of an adjusting screw 11. The adjusting screw 11 is rotatable on the adjusting lever 7, but substantially axially non-displaceable The adjusting lever 7 has an opening 12 through which a screwdriver can be passed and attached laterally to the screw head of the adjusting screw 11, the longitudinal direction of a screwdriver attached to the adjusting screw 11 and the longitudinal axis of the adjusting screw 11 enclosing an angle of approximately 90 ° By a person induced adjustment of the adjusting screw 11, the nut 10 can be moved along the screw shank 9, so that the position of the point of application of the spring device 8 relative to Rotational axis (P) (Fig. 1a) of the control lever 7 is variable, so that the point of the spring device 8 relative to the axis of rotation (P) of the actuating lever 7 in the directions of the double arrow drawn to and from this is adjustable. By the reference numeral 13 is an abutment which cooperates with the adjusting screw 11.
    Fig. 2a shows a possible embodiment of an actuator 5 in a perspective view. The actuator 5 has a housing 14, wherein the spring device 8 is supported via a spring holder 17 on a housing-fixed spring base 16. The spring holder 17 is designed to receive at least one (or more) spring device (s) 8. The spring device 8 comprises at least one helical spring (in particular a compression spring) which presses against the nut 10. The nut 10 is adjustable by a rotation of the adjusting screw 11 along the screw shank 9 relative to the axis of rotation (P) of the adjusting lever 7. The two-armed lever 7 acts as a reversing lever, which transmits the force of the spring device 8 via the transmission lever 15a, 15b, 15c and 15d on the actuator arm 6 and the actuator arm 6 pivots about the adjusting axis (S).
    Fig. 2b shows the circled in Fig. 2a area in an enlarged view. Recognizable is the adjusting screw 11, which has a screw head 11a and an adjoining screw shank 9 with a thread. Evident is an inhibiting device 19, which is effective between the screw head 11a and an abutment 13. The inhibiting device 19 comprises in the figure shown - preferably knob-shaped - surface elements 18, which can be arranged on the underside and / or on the peripheral edge of the screw head 11a. The nub-shaped surface elements 18 are - due to the acting force of the spring device 8 - with pressure on the housing-fixed abutment 13 of the housing 14 at. The abutment 13 is formed in the illustrated embodiment as a bolt on which the knob-shaped surface elements 18 are supported. By the surface elements 18 an uncontrolled adjustment of the adjusting screw 11 is prevented because they inhibit a revolution of the adjusting screw 11. With a controlled rotation of the adjusting screw 11 by a user, the cambered surface elements 18 are each supported on the abutment 13, whereby the screw head 11 a at regular intervals in each case lifted by the height of the knob-shaped surface elements 18 relative to the abutment 13 and against the force of the spring device 8 is, so that the adjusting screw 11 can be positioned in predetermined rotational positions. By the provided inhibiting device 19, the screw shank 9 can also be provided with threads which allow a quick adjustment of the nut 10 relative to the screw shaft 9 upon actuation of the adjusting screw 11. The thread of the screw shank 9 may be formed, for example, as a thread with a high pitch and / or as a two- or multi-start thread. The use of a two- or multi-start thread has the advantage that the load capacity of the seat of the nut 10 is improved on the screw shaft 9 against a catchy thread with high pitch.
    3a shows a perspective view of the adjusting lever 7, on which the adjusting device 20 is mounted. The adjusting lever 7 is pivotally mounted in the position of use about the axis of rotation (P). At the bottom of the screw head 11a a plurality of surface elements 18 are arranged distributed in the region of the peripheral edge of the screw head 11a, which are respectively supported on the abutment 13 in the form of the bolt. In an adjustment by means of a screwdriver - which is passed through the opening 12 - the adjusting screw 11 can be controlled twisted, whereby by the interaction of the knob-shaped surface elements 18 with the abutment 13, a controlled adjustment is possible, an uncontrolled adjustment, however, is prevented, in particular, if the thread of the adjusting screw 11 has no inherent self-locking. Fig. 3b shows the circled in Fig. 3a area in an enlarged view.
    Fig. 4a shows a possible embodiment of an adjusting screw 11 in a perspective view. At the bottom of the screw head 11a, a plurality of surface elements 18 are arranged, which cooperate with an abutment 13 of the actuator 5, respectively. The screw shaft 9 is provided with a thread 21, which compared to a standard thread a two or more times
    Slope. In this way, even at low rotations of the adjusting screw 11, a correspondingly high adjustment of the nut 10 can be brought about.
    Fig. 4b shows an alternative embodiment of the adjusting screw 11, wherein the thread 21 is designed as mehrgängiges, preferably three-threaded thread 21. The pitch of the thread 21 of FIG. 4b may be the same height as the pitch of the thread 21 in Fig. 4a executed, however, the load capacity of the seat of the nut 10 is improved because compared to Fig. 4a a plurality of screw threads of the thread 21 at the same time the nut 10 are received. Multi-start thread 21 have a relatively large pitch angle and can already bring about a strong axial displacement of the nut 10 with a partial rotation of the adjusting screw 11. If the thread 21 is designed to be double-threaded, then a new thread begins every 180 °, with a three-thread 21, a new thread starts every 120 °. FIG. 4c shows an enlarged view of the area circled in FIG. 4b, wherein two threads 21a, 21b offset by 120 ° terminate at the end of the screw shank 9. The pitch of the thread 21 may be at least 1.6 mm, preferably at least 2.4 mm.
    5a-5d show various embodiments of the inhibiting device 19 for inhibiting an uncontrolled rotational movement of the adjusting screw 11. In Fig. 5a noppenfömige surface elements 18 are formed on the underside of the screw head 11a, which are supported to inhibit uncontrolled rotational movement of the adjusting screw 11 on the abutment 18 , In Fig. 5b, a relief-like structure of the surface elements 18 can be seen, which is also located on the underside of the screw head 11a and which cooperates with the abutment 13. In Fig. 5c is a surface element 18 in the form of an elongated groove or recess recognizable, wherein the bolt-shaped abutment 13 is pressed after the rotation of the adjusting screw 11 by 360 ° in this groove or recess. In Fig. 5d surface elements 18 can be seen, which are arranged on the peripheral edge of the screw head 11a, wherein the surface elements 18 according to FIG. 5d with a lateral abutment 13a cooperate. The abutment 13a at least partially surrounds the peripheral edge of the screw head 11a and cooperates with the peripheral edge of the screw head 11a in the manner of a slip clutch, the screw head 11a slipping after overcoming a torque to be applied relative to the abutment 13a.
