The aim of the invention is to provide a solution which allows for the furniture designed for sitting/lying, especially slatted frames, to be adjustable by a motor and for the motors to remain unobtrusive. To this end the invention provides for direct-drive motors (10) integrated into swivel shafts (9) to be positioned on the frame (2) of the slatted frame (1).

Description

Sitting / Lying furniture with adjustable members, especially slate frames {FURNITURE FOR SITTING / LYING, ESPECIALLY SLATTED FRAME, WITH ADJUSTABLE ELEMENTS}

Sitting and lying furniture with adjustable members, especially slate frames, are increasingly equipped with regulating motors to create simple adjustment possibilities that save power on all objects, making them suitable for use by the elderly and / or disabled. More. Although regulating motors are generally used in this furniture, they have a significant amount of space and have the disadvantage that they are not visually beautiful in relatively light and fragile furniture or in beds that are not covered by wide sides.

The driving technique for the slate frame is described, for example, in German publications DE-195 42 319-A1, DE-195 42 320-A1 and DE-195 42 321-A1. It was formed as an external electric motor acting on the shaft in the slate frame.

The present invention relates to a sitting / laid furniture, in particular a slatted frame, comprising an adjustable member, for example a bed with an adjustable head and foot, in which a motor is provided for adjustment. ,

1 is a side view of the adjustable slate frame in its starting position,

2 is a side view of the slate frame according to FIG. 1 with the head and foot portions raised;

FIG. 3 is a longitudinal sectional view of a direct electric motor integrated inside the swing shaft in the frame of the slate frame, including a drive shaft with self-braking powertrain and a quadrilateral wheel.

It is an object of the present invention to provide a solution which makes it possible for a sitting / lying furniture, in particular a slate frame, to be controlled using a motor while at the same time making the motor inconspicuous.

The object is achieved according to the invention by providing the frame of the slate frame with a direct electric motor integrated inside the swing shaft,

As a result, the direct electric motor of the above method integrated inside the swing shaft according to the present invention does not appear to the outside visually, because the direct electric motor is fixed to the frame of the slate frame and the pivot shaft of the slate frame is required at any time. Because it is integrated inside. This solution facilitates sliding at the same time, produces no noise and overall management.

Preferably, two pivoting shafts are provided having a direct electric motor and an associated pivoting lever, the pivoting lever being fixed to the head and / or foot. In this way, the head part and / or foot part can be adjusted independently of each other, and furthermore, the head part and the foot part are each formed once again so that they can be divided into themselves, so that the bed can be adjusted in particular.

In a preferred embodiment, it is proposed that the direct electric motor is rotatably fixed to the outer frame of the slate frame via the shaft sheet, in which the pivot shaft is arranged to be rotatable about the motor via the sliding bearing. This action makes a very stable arrangement of the whole device. Thus, for example, a hexagonal holding bolt is installed in the shaft sheet, and the motor flange is inserted into the holding bolt by a correspondingly formed quadrilateral hole. When the motor shaft is actuated by the windings above it, the motor housing is secured against bending and is rotatably supported by the outer frame of the slate frame.

According to the invention, the motor shaft actuates a carrier acting on the pivot shaft via a self-braking transmission. The advantage of this method of operation is that the adjustable members of the slate frame can be securely held in their respective positions continuously, since the self-braking powertrain prevents the adjustable members from playing back to their starting position. Because. Only when a voltage is supplied to the regulating motor is the braking of the self-braking powertrain released, which can then be changed to another state. As soon as the power supply is interrupted or cut off, the transmission is self-braking and the slate frame is fixed in the desired state.

For this purpose the invention proposes, in a further preferred embodiment, to form the pivot axis as a rectangular tube and the carrier as a square wheel. This configuration allows for a very simple and cost-saving configuration of the adjusting device and allows the carrier and the swing shaft to be coupled to each other without slipping.

The invention is explained in detail below with reference to the drawings.

The slate frame, indicated generally at 1, comprises an outer frame 2, an inner frame 3, a spring member 4 and multiple connectors 5 fixed therein. The shaft sheet 6 is fixed to the outer frame 2 by means of a quadrilateral holding bolt 7. The shaft seat 6 further comprises two sliding bearings 8. On the sliding bearing 8 there is a rectangular tube 9 which is a movable pivot shaft. In the pivot shaft formed of the rectangular tube 9 a direct electric motor 10 is incorporated, which includes a motor shaft 12 having a motor housing 11 and a coil 13.

In addition to the self-brake transmission 14, a drive shaft 15 is provided having a carrier 16 formed of a quadrilateral wheel, which is secured by a stopper 17. On the other side of the direct electric motor 10 there is a motor flange 18 having a square hole 19, with a square holding bolt 7 inserted into the square hole on the shaft sheet 6. The motor shaft 12 and the drive shaft 15 are rotatably supported on the ball bearing 20.

The drive motor 10 is coupled to the transformer 22 and the control device, which is not shown in detail, via the connecting cable 21. The pivoting lever 23 is assigned to the pivoting shaft formed of the rectangular tube 9, which is fixed to the head 24 and / or the foot 25 of the slate frame 1.

The operation of the proposed device is as follows:

1 shows the slate frame in its starting position. When the voltage is supplied to the direct electric motor 11 via the connecting cable 21 by the transformer 22, a quadrangle wheel (with which the motor shaft 12 and the drive shaft 15 are securely twisted to the drive shaft as a carrier) 16) rotates together. The square wheel 16 is inserted from the inside into the rectangular tube 9, which rectangular tube acts as a pivoting shaft and is rigidly fixed to the head 24 and / or via the pivoting lever 23. It is fixed to the foot part 25. The head portion 23 and / or the foot portion 24 are raised as desired. As soon as the desired position is reached, the motor 11 stops.

By correspondingly forming the control device, not only can the head portion 24 and the foot portion 25 be raised or lowered toward each other at the same time, but also the members can be changed to their respective states independently of each other. Of course, the pivoting lever, the insertion frame, the pivoting shaft, etc. may be formed differently. It is important, however, that the intrinsic motor is integrated as a direct electric motor inside the swing shaft, saving space, in order to avoid visual distraction as much as possible.

Sitting and lying furniture according to the invention are suitable for use by the elderly and / or disabled.
