Dual electromotive furniture drive

Abstract

A dual electromotive furniture drive (10), which has a housing, which is provided with drive motor (11), which is drive-coupled to a speed reduction gear mechanism (12), and in which a spindle (14) which is secured against rotation can be moved in its longitudinal direction by means of the speed reduction gear mechanism (12), and in which at least the speed reduction gear mechanism (32) and the spindle (14) are arranged in the housing, and in which the end positions of each spindle (14) are limited by at least one end switch (17), should be designed such that the number of components is minimized, which furthermore is simple and easy to fit and can be produced in a material-saving manner, in which the internal force profiles are optimized and the force transmission paths through the wallsof the housing are short. According to the invention, provision is made for a pressure piece (15) to be arranged on the spindle (14) on that side which is averted from the speed reduction gear mechanism (12), said pressure piece being operatively connected to an adjusting element (23) which is fixedly mounted on a moving furniture component. Furthermore, with respect to the installation position of the dual furniture drive (10), the spindle (14) should be inclined relative to the horizontal and also the second spindle should likewise be inclined relative to the horizontal, wherein the angle formed is an obtuse angle. The dual electromotive furniture drive according to the invention is preferably suitable for adjusting the backrest and the foot part of a slatted base.

Description

technical field [0001] The invention relates to an electric double drive for furniture, which has a housing, wherein the housing is of at least two-part construction and has a U-shaped recess in which a rotatable shaft, said shaft is in operative connection with at least one furniture component to be adjusted, and said U-shaped recess has a cover plate, said cover plate can be mounted positively and preferably in the longitudinal direction of said shaft and for shaft fixed and in operative connection with the housing, wherein the double drive for furniture is provided with at least one drive motor, which is drive-coupled to a reduction gear, and wherein, by means of the reduction gear, the A rotationally locked screw moves in its longitudinal direction, and at least the reduction gear and the screw are arranged in the housing, and the respective end positions of the screw are defined by at least one end switch. Background technique [0002] The housing of the electric doubl...

AI Technical Summary

Problems solved by technology

The latter variant described has proven itself, but has the disadvantage that a relatively large number of components is required to implement the furniture drive function

[0006] Another disadvantage of these known designs is that the central region of the housing has only a relatively small cavity for accommodating a control electronics

For this reason, other designs are also known in which the electric motor is arranged in the corresponding end area of ​​the double drive, but this disadvantageously results in a large overall length of the double drive
