    The present invention relates to an actuator for moving a movable furniture part, comprising: - at least one movably mounted actuator for moving the movable furniture part, - a spring device for applying force to the actuator, - an adjusting device, by which a force acting on the actuator force of the spring device is adjustable, - wherein the adjusting device has a threaded adjusting screw, wherein the force acting on the actuator force of the spring device via a nut, which is adjustably mounted along the thread, adjustable.
    Furthermore, the invention relates to a piece of furniture with a furniture body and a relative to the furniture body movable flap, wherein the flap is movably supported by an actuator of the type to be described.
    An actuator in the form of a so-called flap support is described for example in DE 100 19 337 A1. This flap support comprises two articulated arm parts, wherein a flap-side arm member is acted upon by the force of a compression spring in the opening direction. To adjust the force exerted on the flap, an adjustment device is provided which comprises a threaded bolt and a threaded nut threadedly engaged with the threaded bolt.
    In adjusting devices with an adjusting screw and a nut mounted thereon, the problem often arises that upon rotation of the adjusting screw, the nut becomes jammed upon reaching an end position with the screw head (i.e., with the annular surface formed below the screw head). If such a jamming occurs between the nut and the screw head, it can only be released again with an increased manual effort. In addition, if the nut serves as an abutment for the spring device, it must be possible to loosen this jamming 2/17 " &Quot; In addition, the force of the spring device can be overcome. If, however, the nut is moved to the free end portion of the adjusting screw, it would be possible that the threaded engagement between the nut and adjusting screw is released. The functionality of the adjusting device would therefore no longer be guaranteed.
    Object of the present invention is therefore to provide an actuator of the type mentioned above while avoiding the above drawbacks.
    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 therefore provided that at least one spring element is provided, via which the nut can be acted upon by at least one end region of the adjusting screw with a force pointing away from this end region.
    In other words, at least one of the spring device separate spring element is provided, which presses the nut on reaching an end portion of the adjusting screw in the direction of the opposite end portion of the adjusting screw. Thus, on the one hand jamming of the nut with the screw head can be effectively prevented, on the other hand - if necessary - a spring element can also be provided to prevent detachment of the nut from the thread at a free end of the adjusting screw.
    To provide an abutment for the spring element can be arranged on at least one end portion of the adjusting screw, a stop surface on which the spring element can be supported. This stop surface may be formed by a screw head (in particular by the annular surface formed below the screw head) of the adjusting screw. 3/17 n " 3 ° 0.1
    According to one embodiment, the spring element is designed as a separate component from the nut. The spring element can be designed as a helical spring or alternatively as, preferably arcuately biased, leaf spring. It is also possible that the spring element is connected to the screw head or with this one piece (for example, as a plastic injection molded part) is executed.
    The spring device for acting on the actuator can - preferably directly - abut the nut, but it is also possible that the spring device acts indirectly (for example via at least one intermediate lever or the like) on the nut.
    According to a possible embodiment, the actuator is designed as a pivotable about an axis of rotation mounted actuator. But it is also possible that the actuator is mounted linearly displaceable, for example in the form of a piston rod which is slidably mounted relative to a housing receiving the spring device.
    Further details and advantages of the present invention will become apparent from the embodiment shown in the figures. It shows or show:
    Fig. 1a, 1b Fig. 2 Fig. 3 Fig. 4 Fig. 5a-5c a furniture with a hochbewegbaren flap in a closed position and in an open position, a cross section of an actuator with maximum spring preload, a cross section of an actuator with minimal spring preload, the Actuator in an exploded view, the actuator and two different detail views in perspective views. 4.17
    1a shows a perspective view of a piece of furniture 1 with a furniture body 2 and with a movable furniture part 3 in the form of a flap 4, which is mounted so that it can move upwards relative to the furniture body 2. Fig. 1b shows the furniture 1 with the flap 4 in an open position, wherein the flap 4 is pivotally mounted by hinges 22 against a cabinet cover 23 of the furniture body 2. For moving the flap 4, an actuator 5 is provided with a housing 6 which is pivotally supported relative to the furniture body 2 on a bearing axis 21. Furthermore, the actuator 5 comprises a movably mounted actuator 7, which is formed in the embodiment shown as an actuator arm 9, which is mounted pivotably in the mounting position about a horizontal axis of rotation. By the actuator 5, the flap 4 between a vertical closed position (Fig. 1a) and a swung-up, the access to the furniture body 2 releasing open position (Fig. 1b) movably mounted. The pivotally mounted actuating arm 9 is connected to the flap 4 via an axis 24.
    Fig. 2 shows the actuator 5 in a cross section, wherein the actuator 7 is pivotally mounted in the form of the actuating arm 9 about a horizontal axis of rotation in mounting position 10. The free end of the actuator arm 9 is to be connected via the axis 24 articulated to the flap 4. The actuator 5 comprises a housing 6 to be fastened to the furniture body 2 in which a spring device 11 is accommodated. In the exemplary embodiment shown, the spring device 11 comprises at least one compression spring formed as a helical spring, but it is also possible to provide two or more helical springs, which are preferably connected in parallel. The spring device 11 is supported at one end on an abutment in the form of a nut 12, the other end of the spring device 11 abuts against a slide 18, which is mounted relative to the housing 6 slidably. The nut 12 is movably supported along a thread 17 of an adjusting screw 16. On the slider 18, a pressure roller 19 is rotatably mounted, wherein the actuating arm 9 via a control cam 20, on which a loaded by the spring device 11 pressure roller 19 runs, is pivotable. The control cam 20 is arranged or formed in the illustrated figure on the actuating arm 9, wherein the control cam 20 forms a different radial distance from the axis of rotation 10 of the actuating arm 9. The cam 20 is designed so that the actuating arm 9 5/17 n 'on na%' r is pressed towards the end of the closing movement in the full closed position. During the opening movement of the actuating arm 9, the pressure roller 19 reaches a vertex of the control cam 20, wherein the actuating arm 9 is pressed by the force of the spring device 11 in the open position. For damping the closing and / or opening movement, it is also possible to provide a damper (not shown here), in particular a fluid damper. By an adjusting device 13, the force acting on the actuating arm 9 of the spring device 11 is adjustable. The adjusting device 13 comprises an adjusting wheel 14 with a receptacle 15 for a tool, wherein the adjusting wheel 14 via a gear, preferably a bevel gear, cooperates with the head of the adjusting screw 16. By a brought about by a tool rotational movement of the adjusting 14, the adjusting screw 16 is rotatable, wherein the nut 12 moves along the thread 17. Alternatively, the adjusting wheel 14 may also be designed for manual operation. In the figure shown, the nut 12 is in a position in which the spring device 11 is maximally biased, i. that the force acting on the actuator arm 9 spring force is highest. Visible is a spring element 26, via which the nut 12 can be acted upon at least one end region of the adjusting screw 16 with a force pointing away from this end region. In the illustrated embodiment, the spring element 26 is formed as an arcuate prestressed leaf spring, which the nut 12-if this is adjacent to the underside of the head of the adjusting screw 16 - pushes away with a force acting in the longitudinal direction of the adjusting screw 16 force from the head of the adjusting screw 16. The adjusting screw 16 also has a non-threaded portion 25, the function of which will be explained in the following figure.
    Fig. 3 shows the actuator 5 of Fig. 2, but with the nut 12 in a position in which the spring device 11 is least biased, i. that the force acting on the actuator arm 9 spring force is the lowest. In order to prevent jamming between the nut 12 and the head of the adjusting screw 16 when adjusting the force of the spring device 11, the adjusting screw 16 is provided with a non-threaded portion 25, through which the nut 12 from the thread 17 of the 6/17 .. ... 6 "
    Adjusting screw 16 can extend. The threaded engagement between the nut 12 and thread 17 is thereby canceled, the adjusting screw 16 rotates by a rotation of the adjusting 14 through empty. This has the advantage that the nut 12 can not jam with the head of the adjusting screw 16 at the minimum setting of the spring force. Moreover, this end position is acoustically noticeable to a user with a clicking sound. Thus, the nut 12 is in rotation in the opposite direction again in the thread 17 of the adjusting screw 16, between the nut 12 and the underside of the head of the adjusting screw 16, a spring element 26 is effective, which pushes the nut 12 upwards and the nut 12th again can engage positively in the thread 17 of the adjusting screw 16. The force of the spring element 26 is to be dimensioned so that it can overcome the force acting from the spring device 11 force on the nut 12. In this way, the nut 12 is pressed by the force of the spring element 26 and against the force of the spring device 11 with a sufficiently large holding force against the thread 17 of the adjusting screw 16.
    Fig. 4 shows an exploded view of the actuator 5. The actuator 7 in the form of the pivotable actuator arm 9 is on the one hand to connect to an axis 24 with the flap 4, on the other hand, the actuator arm 9 is pivotally mounted on the body side about the axis of rotation 10 (hinge pin 28). On the actuating arm 9, parts which form the control cam 20 are fastened on both sides. In mounting position, a pressure roller 19, which is rotatably mounted on a hinge pin 27, run on the control cam 20 of the actuating arm 9. The pressure roller 19 is arranged on a loaded by the spring device 11 slide 18, which is mounted linearly displaceable within a tubular portion 35. The spring device 11 is supported on a nut 12, which is adjustably mounted on a thread 17 of the adjusting screw 16. The adjusting screw 16 has a stop surface 37 on which at least one spring element 26 can be supported. The spring element 26 is formed in the embodiment shown as a bow-biased leaf spring. Between the thread 17 and the stop surface 37, a threadless portion 25 is formed, which a direct contact of the nut 12 with the 7/17 r '..... 7 ........
    Stop surface 16 of the adjusting screw 16 prevents. By attaching and rotating a tool on the receptacle 15 of a Verstellrades 14, the adjusting screw 16 is rotatable. A housing 6, which comprises the two housing parts 6a and 6b, is to be fastened via a bearing part 29 and a retaining bolt 32. The upper end forms a cap 30 which on the pivot axis 10 forming hinge pin 28 can be snapped. As a special feature is still a display device 38 to call, by which the force acting on the actuator arm 9 of the spring device 11 can be displayed. This display device 38 comprises guide parts 36a and 36b, which are motion-coupled with the nut 12. On at least one guide part 36a, a projection 34 is formed, which engages in a slot 33 of the tubular portion 35. In an adjustment of the adjusting screw 16 so also the projection 34 of the guide member 36 a is moved, with the position of the projection 34 relative to the slot 33 of the tubular portion 35 changes. The relative position between projection 34 and slot 33 is a recognizable for a person measure of the respective set force of the spring device 11. In addition, the tubular portion 35 can also be provided with a scale through which a person can read the value of the spring preload.
    5a shows the actuator 5 in a perspective view, wherein for reasons of clarity of the shown in Fig. 4 tubular portion 35 (in which the movable slide 18 is received) and the housing 6 with the two housing parts 6a and 6b are not shown , The pressure roller 19 is due to the force of the spring device 11 on the control cam 20 of the actuating arm 9, wherein by the adjusting device 13, the spring force acting on the actuating arm 9 is adjustable. The guide members 36a and 36b with the projections 34 are positively connected to the nut 12. Good is also the spring element 26, which is effective between the head of the adjusting screw 16 and the nut 12.
    Fig. 5b shows the lower portion of the actuator 5 in an enlarged view. By a rotation of the adjusting wheel 14, the adjusting screw 16 and thus the position of the nut 12 can be adjusted. 8/17 8
    Fig. 5c shows the actuator 5 in a view from below, wherein the adjusting wheel 14 via cooperating teeth with the adjusting screw 16 is in communication. The adjusting wheel 14 is rotatably mounted about an axis of rotation, wherein the direction of the axis of rotation of the adjusting wheel 14 transverse to a longitudinal axis of the adjusting screw 16, preferably approximately at right angles, runs. This force deflection has the advantage that a screwdriver for adjusting the adjusting wheel 14 laterally, i. can be attached and rotated in mounting position approximately perpendicular to a side wall of the furniture body 2, with a particularly comfortable, easily accessible and moderately easy adjustment of the biasing force of the spring device 11 is possible.
