    专利说明:

    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 actuating the actuator, an adjusting device by means of which a force acting on the actuator force of the spring device is adjustable, - Wherein the adjusting device has a threaded portion and an adjustably mounted between two end positions nut, wherein the force acting on the actuator member of the spring device is adjustable by adjusting the nut along the threaded portion.
    Furthermore, the invention relates to an arrangement with a movable furniture part, which is movably mounted on 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 an adjustable threaded bolt and a threaded nut threadedly engaged with the threaded bolt.
    In adjustment devices with a nut, which is adjustably mounted along a threaded portion, the problem often arises that the nut clamps on reaching an end position with a counter-stop (for example, with the underside of a screw head). If such jamming occurs between the adjustable nut and the counter-stop, it can only be released with an increased manual effort. The release of the jamming is also made more difficult by the force of the acting spring device, because a person must solve the deadlock against the force of the spring device by increased force.
    Object of the present invention is therefore to provide an actuator of the generic type mentioned while avoiding the above disadvantages.
    This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are indicated in the dependent subclaims.
    According to the invention, it is thus provided that at least one support element is provided, which relieves the nut in at least one of the two end positions from the force of the spring device.
    In other words, the force of the spring device in at least one of the two end positions of the nut is not initiated by the nut itself, but via the support member in a housing part of the actuator. The nut is thus unloaded in at least one end position by the force of the spring means, so that the nut is easy to adjust without an axial pressure exerted by the spring means.
    To support the support element, it may be favorable if the actuator has a housing, wherein the support element is supported on a housing-fixed counter-stop.
    Further details and advantages of the present invention will become apparent from the embodiment shown in the figures. It shows or show:
    1a, 1b a furniture with a highly movable flap in a closed position and in an open position,
    2a, 2b show an embodiment of an actuator in a perspective cross-section and an enlarged illustration of the same,
    3a, 3b the actuator in a perspective section and a detail area in an enlarged view,
    4a, 4b, the actuator with an adjusted nut in a perspective cut and a detail area in an enlarged view,
    5a, 5b, the actuator in a perspective cross-section with an in-position end nut and an enlarged illustration of this.
    1a shows a perspective view of a piece of furniture 1 with a furniture body 2and with a movable furniture part 3 in the form of a flap 4, which is mounted so that it can be moved 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 supported 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 mounted relative to the furniture body 2 on a bearing axis 21. Furthermore, the actuator 5 comprises a movably mounted actuator 7, which in the embodiment shown is designed as an actuating arm 9, which in the mounting position is pivotable about a horizontal axis of rotation 10 (FIG. 2a). By the actuator 5, the flap 4 between a vertical closed position (Fig. 1a) and a hochgeschwenkten, 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. 2a shows the actuator 5 in a perspective 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. The free end of the actuator arm 9 is pivotally connected to the flap 4 via the axle 24. The actuator 5 includes a housing 6 to be fixed to the furniture body 2, in which a spring device 11 is received. In the exemplary embodiment shown, the spring device 11 comprises at least one compression spring designed as a helical spring, but it is also possible to provide two or more helical springs, which are preferably connected in parallel. A first end portion of the spring device 11 is supported on a support member 27, a second end portion of the spring device 11 abuts against a slider 18, which is linearly slidably mounted in the longitudinal direction of the housing 6. The spring device 11 abuts indirectly via the support member 27 on an adjustably mounted by an adjusting device 13 nut 12, wherein the support member 27 moves in an adjustment of the nut 12 in the longitudinal direction of the housing 6. On the slider 18, a pressure roller 19 is rotatably mounted, wherein the actuating arm 9 via a control cam 20, on which the loaded by the spring device 11 pressure roller 19 expires, is pivotable. The control curve 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 control cam 20 is designed so that the actuating arm 9 is pressed into the fully closed position towards the end of the closing movement. 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 in the open position by the force of the spring device 11 becomes. To dampen the closing and / or opening movement of the actuating arm 9, it is also possible to provide a damper (not shown here), in particular a fluid damper.
    Fig. 2b shows the circled in Fig. 2a area in an enlarged view.Durch an adjusting device 13, the force acting on the actuator arm 9 of the spring device 11 is adjustable. The adjusting device 13 comprises an adjusting wheel 14 (preferably designed for tool actuation) which cooperates with the head of an adjusting screw 16 via a gear (preferably a bevel gearbox). Via a tool-induced rotational movement of the adjusting wheel 14, the adjusting screw 16 is rotatable, with the threaded nut 12 moving along the threaded portion 17 of the adjusting screw 16. Alternatively, the adjusting wheel 14 can also be designed for manual operation. The support element 27 is formed in the embodiment shown as - preferably step-shaped - sleeve, which surrounds the threaded portion 27 at least in sections and which is loosely mounted on threaded portion 17, that is, with the threaded portion 17 is not in threaded engagement.
    The support member 27 rests on the one hand on the spring device 11, on the other hand on derverstellbaren nut 12. The support member 27 has in the figure shown two stops 28, which in a screw head of the adjusting screw 16 facing end position with a housing-fixed counter-stop 29 (here with a transverse to the longitudinal direction of the housing 6 web of the housing 6) cooperate. In this way, the nut 12 in the said end position is completely relieved of the force of the spring device 11. Also recognizable is a spring element 26, by means of which the nut 12 can be acted on at one end region of the adjusting screw 16 with a force pointing away from this end region. By the spring member 26, when the spring force is adjusted, jamming of the nut 12 with the screw head can be effectively prevented. To prevent a lock between the nut 12 and the head of the adjusting screw 16 is provided that connects to the threaded portion 17, a threadless portion 25, wherein the nut 12 enter in one of the two end positions in this threadless portion 25 and the threaded portion 17 is disengageable. The threaded engagement between the nut 12 and threaded portion 17 can be canceled in this way, 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, the extension of the nut 12 from the threaded portion 17 is noticeable to a user with an audible click sound. In order for the nut 12 to re-enter the threaded portion 17 upon rotation of the adjusting wheel 14, between the nut 12 and the underside of the head of the adjusting screw 16 is the spring element 26 acting to urge the nut 12 upward so that the nut 12 is inserted into the threaded portion 17 of the adjusting screw 16 can again interlock positively. On the other hand, when the nut 12 has emerged from the threaded portion 17 and cooperates with the unthreaded portion 25, the nut 12 is fixed to the housing by supporting the support member 27
    Counter stop 29 relieved of the force of the spring device 11. Due to the fact that in the end position no spring force acts on the nut 12, the force of the spring element 26 can be dimensioned very small. A cost-effective production results when the spring element 26 is formed as a spring-trained plastic injection molded part.
    Fig. 3a shows the actuator 5 in a perspective cross-section, wherein the movably mounted actuator 7 for moving the movable furniture part 3 is not shown. Fig. 3b shows the area circled in Fig. 3a in an enlarged view. The adjustable nut 12 is engaged with the threaded portion 17 of the adjusting screw 16, while the sleeve-shaped supporting member 27 is only loosely supported on the threaded portion 17. The spring device 11 pushes indirectly on the support member 27 on the adjustable nut 12, wherein a first support surface 31 of the nut 12 abuts a second support surface 32 of the support member 27. The force of the spring device 11 is hereby recorded as vonov the nut 12. Evident is the stop 28 of the support element 27, which cooperates in a lower end position of the nut 12 with a housing-fixed counter-stop 29 and thereby fully relieves the nut 12 in this end position of the force of the spring device 11. The support member 27 is provided with a, preferably step-shaped, recess 30 for receiving the nut 12. The support member 27 surrounds the nut 12 completely, wherein the stopper 28 projects beyond the nut 12 in the direction of the housing-fixed counter-stop 29.
    Fig. 4a and the enlarged detail view of FIG. 4b show the actuator 5 mitverstellter nut 12, so that therefore acting on the actuator 7 force of the spring device 11 is reduced in comparison to the Fig. 3a, 2b. The nut 12 is just in engagement with the threaded portion 17, the stop 28 of the support member 27 is located to the housing fixed counter-stop 29 in a spaced position. The first support surface 31 of the nut 12 and the second support surface 32 of the support member 27 continue to abut each other.
    Fig. 5a and the enlarged detail view of Fig. 5b show the actuator 5 miteiner in the end position nut 12, so that acting on the actuator 7 bias is the lowest. The nut 12 is now at the unthreaded gate 25 of the adjusting screw 16, the stop 28 abuts the housing-fixed counter-stop 29 and the force of the spring device 11 is introduced into the housing 6 of the actuator 5. The first support surface 31 of the nut 12 and the second support surface 32 of the support member 27 are now in a spaced position relative to each other. By this introduced into the housing 6 load change the nut 12 is relieved of the force of the spring device 11. The spring element 26 pushes the nut 12 away from the head of the adjusting screw 16, i.e., the nut 16. in the direction of the threaded portion 17. In this way, jamming between nut 12 and adjusting screw 16 is prevented, by the force of the spring element 26, the nut 12 can be centered relative to the threaded portion 17 upon corresponding actuation of the adjusting device 13 (FIG.
