Abstract
Description
【Technical Field】 【0001】 The present invention relates to a fitting formed as a furniture fitting or a structural fitting for movably supporting a swiveling element, in particular a movable furniture part, relative to a stationary structure, in particular a furniture cabinet, the fitting comprising: - at least one base body to be fixed to the stationary structure; - at least one actuating arm to be coupled to the swiveling element; - at least one spring device for applying a force to the at least one actuating arm, the spring device being supported on the at least one base body via at least one support device; - at least one transmission mechanism for transmitting the force of the at least one spring device to the at least one actuating arm, the transmission mechanism having at least one transmission lever pivotable about a pivot axis; - at least one force adjustment device for adjusting the force of the spring device on the at least one actuating arm and relates to a fitting. 【0002】 Furthermore, the present invention relates to a furniture comprising a stationary structure, in particular a furniture cabinet, at least one swiveling element, in particular a movable furniture part, movably supported relative to the stationary structure, and at least one fitting of the type described for moving the swiveling element relative to the stationary structure. 【0003】 In a furniture drive for moving a furniture flap, as disclosed in WO 2006 / 005086, a preload is applied by a spring device to a pivotably supported actuating arm in order to compensate for the weight of the furniture flap. The spring device is pivotally coupled to an intermediate lever via an adjustable point of action, in which case the intermediate lever pivots the actuating arm via a pressing roller - control cam assembly. By adjusting the point of action on the intermediate lever, the preload of the spring device can be changed, thereby enabling different weights of the swiveling element coupled to the actuating arm to be compensated for. 【0004】 The force of the spring mechanism is limited by the compressed length of the spring (i.e., the length of the spring when fully compressed). For heavier furniture flaps, a spring mechanism with a higher spring force must be provided. However, such a higher spring force also means that the movable furniture part is pressed against the furniture cabinet with a higher relative pulling force when in the closed position. The user must overcome this pulling force by manually pulling on the movable furniture part each time they open it, which requires increased force consumption and is often cumbersome for the user. 【0005】 The object of the present invention is to provide a fitting that improves upon the type of fitting described at the beginning and avoids the drawbacks discussed above. 【0006】 This problem is solved by the features of claim 1 according to the present invention. Another advantageous configuration of the present invention is defined in the dependent claims. 【0007】 According to the present invention, preferably, at least one adjustment device (10) separate from at least one force adjustment device (8) is provided, and it is assumed that the position of at least one pivot axis (11) of at least one transmission lever (9a) relative to the base (5) can be adjusted by this adjustment device (10). 【0008】 In other words, the fitting has an adjustment device in addition to a force adjustment device, which allows the pivot axis of at least one transmission lever to be adjusted relative to the base. Thus, the kinematics of the transmission mechanism can be changed so that a stronger spring device, especially a longer spring device, can be used as standard without significantly changing the pulling force of the operating arm in the closed position. Therefore, the structure according to the present invention can cover a wider range of different weights of the pivot elements. 【0009】 According to a first variant of the present invention, at least one force adjustment device and at least one adjustment device have a common adjustment element, or at least two adjustment elements that are mechanically connected to each other via at least one set of teeth, and it is assumed that the force of a spring device to at least one actuating arm and the position of at least one pivot axis of at least one transmission lever relative to the base can be adjusted simultaneously by the common adjustment element or by the mechanically connected adjustment elements. 【0010】 According to a second variant of the present invention, at least one force adjustment device and at least one adjustment device may have two independent adjustment elements, and these adjustment elements may allow for independent adjustment of the force of a spring device to at least one actuating arm and the position of at least one pivot axis of at least one transmission lever relative to the base. 【0011】 The furniture according to the present invention comprises a stationary structure, in particular a furniture cabinet; at least one pivoting element, in particular a movable furniture part, that is movably supported relative to the stationary structure; and at least one fitting of the present form for moving the pivoting element relative to the stationary structure. 【0012】 The pivot element may be supported so as to be pivotable about at least one pivot axis in the horizontal or vertical direction, and / or the fitting according to the present invention has such a pivot axis. 【0013】 The rotating element may be configured, for example, as a rotating door or flap, for example, as an upward-lifting flap, as an upward-swiveling flap, or as an upward-folding flap. 【0014】 The fittings can be advantageously used not only as furniture fittings for moving movable furniture parts, but also as structural fittings for moving windows or doors. 【0015】 Further details and advantages of the present invention will become apparent from the following description of the drawings.

[Figure 7b] FIG. is a view showing another embodiment of a fitting in which a transmission mechanism has at least one pressing roller - control cam assembly for pivoting an operating arm. 【0017】 FIG. 1a shows a furniture 1 comprising a stationary structure 2, in particular a furniture cabinet 2a, and a pivoting element 3 movably supported relative to the stationary structure 2, in particular a movable furniture part 3a in the form of a furniture flap that can be lifted relative to the stationary structure 2. 【0018】 The pivoting element 3 is supported movably relative to the stationary structure 2 via at least one fitting 4. The fitting 4 comprises at least one base 5 to be attached to the stationary structure 2, at least one operating arm 6 to be coupled to the pivoting element 3, and at least one spring device 7 for applying force to the at least one operating arm 6. 【0019】 The spring device 7 may comprise, for example, at least one, preferably more, coil springs. In the illustrated embodiment, the spring device 7 has at least one tension spring. Alternatively or supplementally, the spring device 7 may have at least one gas spring. 【0020】 The fitting 4 further includes at least one transmission mechanism 9 for transmitting the force of at least one spring device 7 to at least one actuating arm 6, in which case the transmission mechanism 9 has at least one transmission lever 9a that is pivotable about a pivot axis 11. 【0021】 The force of the spring device 7 on at least one actuating arm 6 can be adjusted by at least one force adjustment device 8. 【0022】 In the illustrated embodiment, the force adjustment device 8 comprises at least one rotatably supported adjustment element 8a, in which case the force of the spring device 7 on at least one actuating arm 6 is adjustable by the rotation of the adjustment element 8a. 【0023】 The adjustment element 8a may be formed for manual operation or for operation using a tool, for example, a screwdriver. 【0024】 Furthermore, the fitting 4 has at least one adjustment device 10, which allows adjustment of the position of at least one pivot shaft 11 of at least one transmission lever 9a relative to the base 5. 【0025】 In one possible embodiment, the force adjustment device 8 and the adjustment device 10 are connected to each other, so that the position of the pivot axis 11 of the transmission lever 9a relative to the base 5 can be adjusted by operating the force adjustment device 8 (or vice versa). 【0026】 Figure 1b is a perspective view of the fitting 4. The base 5 to be attached to the stationary structure 2 has two housing walls 5a and 5b that are substantially parallel and spaced apart from each other, and both housing walls 5a and 5b are formed to be in close contact with the stationary structure 2. 【0027】 The base 5 has an upper surface 12a and a lower surface 12b, and these upper surface 12a and lower surface 12b are substantially oriented horizontally when the fitting 4 is assembled. 【0028】 The fitting 4 has a lever mechanism 22 having at least five, preferably at least seven, pivot axes, through which at least one operating arm 6 is movably supported on the base 5. 【0029】 To compensate for the different weights of the pivot elements 3 that can be coupled to the operating arm 6, the preload of at least one spring device 7 can be adjusted by the force adjustment device 8. 【0030】 At least one of the provided adjustment elements 8a has at least one threaded spindle 13 (Figure 1a), or is kinetically coupled to at least one threaded spindle 13, and / or is in a position that is directly reachable for operation from the end faces 12c, 12d of the fitting 4, and / or is oriented obliquely relative to the upper surface 12a and / or obliquely relative to the lower surface 12b of at least one base body 5. 【0031】 Figure 2a shows one embodiment of the metal fitting 4 in the closed position. 【0032】 The base 5 is provided with at least one actuating arm 6 to be coupled to the pivoting element 3, at least one spring device 7 for applying force to the at least one actuating arm 6, and a transmission mechanism 9 equipped with at least one transmission lever 9a. 【0033】 The force adjustment device 8 allows adjustment of the torque acting on the actuating arm 6 of at least one spring device 7. In this way, the different weights of the pivot elements 3 can be compensated for at least partially, making the movement of the pivot elements 3 easier for the user. 【0034】 The spring device 7 is movably supported on at least one base body 5 via at least one support device 14. 【0035】 The force adjustment device 8 preferably comprises at least one rotatably supported adjustment element 8a, in which case the position of the support device 14 relative to the base 5 is adjustable, preferably along the threaded spindle 13, by operating, preferably rotating, at least one adjustment element 8a. 【0036】 The spring device 7 is coupled to at least one transmission lever 9a via the point of action 15. 【0037】 In the illustrated embodiment, the operating point 15 is positioned in a fixed position relative to the transmission lever 9a and / or is positioned spaced apart from the pivot axis 11 of at least one transmission lever 9a. 【0038】 At least one transmission lever 9a has a first end and a second end, the pivot shaft 11 of the transmission lever 9a is located at the first end, and at least one force transmission element 17, preferably a lever, a pressing member, a pressing roller, or a control cam, is located at the second end, to which a load is applied by a spring device 7. 【0039】 In the illustrated embodiment, the force transmission element 17 is preferably formed as a curved lever, which is pivotally connected at one end to the transmission lever 9a and at the other end to the lever mechanism 22. 【0040】 The lever mechanism 22 may have at least five, preferably at least seven, pivot axes. In this way, at least one operating arm 6 can be stably guided between the closed position and the open position. 【0041】 The operating point 15 of the spring device 7 is located between the first end and the second end of the transmission lever 9a in the illustrated drawing. 【0042】 According to one embodiment, the base 5 is provided with at least one support device 14, 16 for supporting a spring device 7 and / or for supporting at least one pivot shaft 11, and the relative positions of the support devices 14, 16 with respect to the base 5 are adjustable by at least one force adjustment device 8 and / or at least one adjustment device 10. 【0043】 In another embodiment, a first support device 16 for supporting at least one pivot shaft 11 and a second support device 14 for supporting a spring device 7 are provided, and preferably both support devices 14,16 may be movably arranged on one common threaded spindle 13, or preferably on two threaded spindles 13,13a that are kinetically connected to each other via at least one set of teeth 19a,19b (Figures 4a to 4d), or on two independent threaded spindles 13,13a. 【0044】 Preferably, it is assumed that the position of the support device 14 of the spring device 7 and the position of the pivot shaft 11 of at least one transmission lever 9a can be adjusted relative to the base 5 by operating the force adjustment device 8. 【0045】 At least one operating arm 6 is movably supported between a closed position and an open position, and in this case, the closing force that can be acted on the operating arm 6 in the closed position by the spring device 7 can be adjusted by adjusting the position of at least one transmission lever 9a. 【0046】 Figure 2b shows the metal fitting 4 shown in Figure 2a together with the operating arm 6 in the open position. 【0047】 Figure 3a shows the fitting 4 in the closed position as shown in Figures 2a and 2b. In this case, the position of the support device 14 of the spring device 7 and the position of the pivot shaft 11 of the steering lever 9a can be adjusted relative to the base 5 of the fitting 4 by operating the force adjustment device 8. 【0048】 By directly comparing with Figures 2a and 2b, the spring mechanism 7 is less tensioned, so this adjustment can be assumed to be for lighter weight pivot elements 3. 【0049】 In other words, the spring mechanism 7 can be designed with a higher strength as a standard, thus compensating for the heavier weight of the pivot element 3. To prevent the stronger spring mechanism 7 from significantly increasing the closing force acting on the actuating arm 6, the position of the pivot axis 11 of at least one transmission lever 9a relative to the base 5 is also changed by the adjustment device 10. 【0050】 Figure 3b shows the fitting 4 in the open position as shown in Figure 3a, in which case the lever 22a of the lever mechanism 22 is in contact with at least one stopper 18 to limit the maximum open position of at least one operating arm 6. 【0051】 At least one stopper 18 may be located on the base 5 and / or may be formed to be adjustable, so that the maximum open position of at least one actuation arm 6 can be adjusted by operating at least one stopper 18, preferably by rotation. Limiting the maximum open position of the actuation arm 6 prevents collision between the pivot element 3 and the ceiling. 【0052】 Figures 4a to 4d show another embodiment of the fitting 4, which has two adjustment elements 8a and 10a connected to each other. 【0053】 Figure 4a shows the fitting 4 in the closed position of the operating arm 6, in which case the spring device 7 is maximally tensioned. In other words, this adjustment compensates for the weight of the heavy pivot element 3, in which case the pivot axis 11 of the transmission lever 9a takes a first position relative to the base 5. 【0054】 The force adjustment device 8 of the spring device 7 for adjusting the torque acting on the operating arm 6 preferably has a rotatable first adjustment element 8a. 【0055】 An adjustment device 10 for adjusting the position of the pivot axis 11 of at least one transmission lever 9a relative to the base 5 preferably has a rotatable second adjustment element 10a. 【0056】 The spring device 7 is movably supported along the first threaded spindle 13 via a first support device 14. The pivot shaft 11 of at least one transmission lever 9a is movably supported along the second threaded spindle 13a via a second support device 16. 【0057】 Both adjustment elements 8a and 10a are preferably connected to each other via at least one set of teeth 19a and 19b, in which case the adjustment elements 8a and 10a connected to each other allow simultaneous adjustment of the force of the spring device 7 on at least one actuating arm 6 and the position of at least one pivot axis 11 of at least one transmission lever 9a relative to the base 5. 【0058】 Both sets of teeth 19a and 19b may be formed, for example, as bevel gears that mesh with each other. 【0059】 Alternatively, at least one joint, such as a cardan joint, may be provided to transmit torque in order to link the rotational motion between both adjustment elements 8a and 10a. 【0060】 Figure 4b shows the fitting 4 according to Figure 4a in the open position of at least one operating arm 6. 【0061】 Figure 4c shows the fitting 4 in the closed position of the operating arm 6, in which case the spring device 7 is less tensioned compared to Figures 4a and 4b. In other words, this adjustment can compensate for the lighter weight of the pivot element 3, in which case the pivot axis 11 of the transmission lever 9a takes a second position relative to the base 5. 【0062】 The second position of the pivot shaft 11 of the transmission lever 9a shown in Figure 4c is different from the first position of the pivot shaft 11 of the transmission lever 9a shown in Figure 4a. 【0063】 When adjusting elements 8a and 10a are operated, the other adjusting elements 10a and 8a are also moved together, and in this case, the support devices 14 and 16 are movable along the threaded spindles 13 and 13a due to the rotation of the adjusting elements 8a and 10a. 【0064】 Each of the support devices 14 and 16 may have one female thread, which is engaged with or can be engaged with the threaded spindles 13 and 13a. 【0065】 Figure 4d shows the fitting 4 according to Figure 4c together with at least one operating arm 6 in the open position. 【0066】 Figures 5a to 5d show another embodiment of the fitting 4, which has at least one guide track 20 for movably supporting the pivot shaft 11 of the transmission lever 9a relative to the base 5. 【0067】 Figure 5a shows the metal fitting 4 together with the operating arm 6 in the closed position. 【0068】 At least one guide track 20 may be positioned on or formed on the base 5 of the fitting 4. In this way, the pivot shaft 11 can be guided along the guide track 20 in a defined manner with improved stability. 【0069】 In the illustrated embodiment, the support device 16 for movably supporting the pivot shaft 11 has at least one elongated hole 21, in which case the pivot shaft 11 of the transmission lever 9a is movable along the guide track 20 of the base 5 and along the elongated hole 21 of the support device 16. 【0070】 A force adjustment device 8 for adjusting the torque to at least one actuating arm 6 and an adjustment device 10 for adjusting the position of the pivot shaft 11 are connected to each other via cooperating gear rows 19a, 19b, as in the embodiment described above. When adjustment elements 8a, 10a rotate, the other adjustment elements 10a, 8a also move together. As a result, both threaded spindles 13, 13a rotate, and the support devices 14, 16 move relative to each other. 【0071】 Preferably, the relative distance between both support devices 14 and 16 may be reduced by operating the force adjustment device 8 and / or by operating the adjustment device 10 for reducing the torque acting on the actuating arm 6. 【0072】 Figure 5b shows the metal fitting 4 from Figure 5a together with the operating arm 6 in the open position. 【0073】 Figure 5c shows the fitting 4 according to Figures 5a and 5b, in which case the preload of the spring device 7 is reduced by operating the force adjustment device 8, and the position of the pivot shaft 11 is also changed. 【0074】 To guide the pivot shaft 11 relative to the base 5, at least one guide track 20 may be provided, which is formed, for example, partially curved and / or directly on the base 5. 【0075】 Alternatively, it may be assumed that at least one guide trajectory 20 is formed as a separate component preferably located on the base 5. 【0076】 Figure 5d shows the metal fitting 4 in Figure 5c together with the operating arm 6 in the open position. 【0077】 Figures 6a to 6d show another embodiment of the fitting 4, in which a force adjustment device 8 and an adjustment device 10 independent of the force adjustment device 8 for adjusting the position of the pivot shaft 11 relative to the base 5 are provided. 【0078】 In other words, in this embodiment, both threaded spindles 13, 13a are no longer kinetically coupled and connected to each other, but are movable independently of each other. This embodiment provides, on the one hand, individual adjustment of the preload of the spring device 7, and on the other hand, adjustment of the pivot axis 11 of at least one transmission lever 9a. 【0079】 Figure 6a shows the metal fitting 4 together with the operating arm 6 in the closed position. 【0080】 Figure 6b shows the metal fitting 4 from Figure 6a together with the operating arm 6 in the open position. 【0081】 Figure 6c shows the fitting 4 shown in Figures 6a and 6b together with the operating arm 6 in the closed position. The torque acting on the operating arm 6 can be adjusted by operating the force adjustment device 8. Independent of the force adjustment device 8, an adjustment device 10 can be operated to adjust the position of the pivot shaft 11 relative to the base 5. 【0082】 Figure 6d shows the metal fitting 4 in Figure 6c together with the operating arm 6 in the open position. 【0083】 Figures 7a and 7b illustrate another embodiment of the fitting 4, in which the transmission mechanism 9 has at least one press roller-control cam assembly for pivoting at least one actuation arm 6. 【0084】 Figure 7a shows the metal fitting 4 together with the operating arm 6 in the closed position. 【0085】 The force transmission element 17, to which a load is applied by the spring device 7, is formed in the illustrated embodiment as a rotatable pressing roller, which is able to travel along a control cam 24 located on or formed on the lever 22a when the operating arm 6 is in motion. 【0086】 This means that the force applied from the spring device 7 to the pivot element 3 via the fitting 4 can be adjusted according to a predetermined course and transmitted to at least one actuation arm 6. 【0087】 In the illustrated embodiment, the control cam 24 is positioned on or formed on the lever 22a of the lever mechanism 22, in which case the lever 22a is pivotably coupled to the base 5 about an axis 23a and pivotably coupled to another lever 22b of the lever mechanism 22 via an axis 23b. 【0088】 Conversely, from a kinematic standpoint, the control cam 24 may be rotatably supported on the force transmission element 17, and the pressing roller may be rotatably supported on the lever 22a of the lever mechanism 22. 【0089】 In the illustrated embodiment, both threaded spindles 13, 13a are connected to each other via cooperating tooth rows 19a, 19b, so that when one threaded spindle 13, 13a rotates, the other threaded spindle 13, 13a also rotates. 【0090】 Thus, when the adjustment elements 8a and 10a are operated, the support devices 14 and 16 are also moved along the threaded spindles 13 and 13a. In this case, the preload of the spring device 7 on the operating arm 6 and the closing force that can be applied to the operating arm 6 in the closed position by the spring device 7 can be adjusted simultaneously. 【0091】 At least one guide track 20 may be provided to guide the pivot axis 11 of the transmission lever 9a relative to the base 5. 【0092】 Figure 7b shows the fitting 4 according to Figure 7a, in which case the relative positions of the support devices 14 and 16 with respect to the base 5 can be adjusted by operating the force adjustment device 8 and / or the adjustment device 10. 【0093】 At least one adjustment element 8a, 10a, preferably both adjustment elements 8a, 10a, may have at least one receiving contour for a tool, such as a screwdriver, in which case the position of the spring device 7 and / or the position of the pivot axis 11 of the transmission lever 9a can be adjusted relative to the base 5 of the fitting 4 by rotating the adjustment element 8a, 10a with the tool.
