Problems solved by technology

Although such an actuating drive allows a compact design, the adjustment options are limited because the actuating contour is arranged between the pressing part and the actuating arm
This leads to problems with unfavorable leverage ratios and consequent profile changes of the actuation profile

Embodiment Construction

[0029] The furniture 1 comprises a cabinet-shaped furniture body 2, which has a side wall 10, an upper panel 15 and a base 14, and a flap 3 is pivotally mounted on the cabinet-shaped furniture body. For this purpose, a flap fitting 4 is provided, by means of which the flap 3 can be pivoted upwards, as indicated schematically by the arrow. The flap fitting 4 is preloaded via a pivot drive not shown here, wherein the spring force depends on the open position of the flap 3 .

[0030] exist figure 1 Among them, the flap fitting 4 is designed, for example, as a multi-joint connection, in particular a seven-joint connection. It is also possible to design trap fittings as four-joint connections, such as figure 2 with image 3 shown. The flap 3 is pivotally mounted on the furniture body 2 and can be moved by means of two parallel levers 5 and 6 held by a connection 7 or 7 ′ on the levers 5 and 6 . exist figure 2 , the flap 3 basically pivots forward and upward, while in ima...

Abstract

A pivot drive (30) for a movable piece of furniture (3, 25, 25') comprises an actuating arm (32), which is mounted such that it can be pivoted about an axis of rotation (31), a spring assembly (33), having at least one spring guided linearly in a working direction, a pressure-exerting component (34, 34'), which is connected to the spring assembly (33) and can be displaced along a control curve (35, 35'), and a housing (21), on or in which the pivot drive is mounted, wherein the actuating arm (32) is connected in a rotationally fixed manner to the spring assembly (33) and can be pivoted therewith about the axis of rotation (31), and it is possible to adjust the control curve (35, 35') relative to the axis of rotation (31), in order to set the spring force of the spring assembly (33), and / orit is possible to adjust the force by which the spring assembly (33) acts on the control curve.

Description

technical field [0001] The present invention relates to a pivot drive for movable furniture and furniture, the pivot drive having: an actuating arm mounted such that it can pivot about an axis of rotation; a spring assembly having at least one a spring assembly guided linearly thereon and a pressing member connected to the spring assembly and movable along the control curved surface; and a housing on or in which the pivot drive is mounted. Background technique [0002] DE 20 2010 015 091 U1 discloses a furniture fitting for driving a flap, in which a power drive with a spring acts on a power deflection lever to pretension the connecting drive in the opening or closing direction. To adjust the force, the coupling element can be adjusted on the deflection lever. The disadvantage here is that, for flaps of different widths and weights, different spring forces and different spring force progressions are required depending on the open position of the flap. The adjustment possib...
