Definitions

• the invention relates to seating / reclining furniture, in particular slatted frames, with adjustable elements, such as e.g. a bed with an adjustable head and foot section, motors are provided for adjustment.
• Servomotors are generally used, but they have the disadvantage that they are relatively space-consuming and have an optically unsightly effect, particularly in the case of lighter, filigree-looking pieces of furniture or, for example, beds that are not covered with wide side parts.
• a drive technology for slatted frames for example, show the German laid-open documents DE-195 42 319-A1, DE-195 42 320-A1 and DE-195 42 321-A1, the drives also being designed as external electric motors there, which are arranged on an axis on the slatted frame act.
• the object of the invention is to provide a solution. - 2 -
• axis motors integrated in swivel shafts are provided on the frame of the slatted frame.
• Axle motors of this type which are integrated into swivel shafts according to the invention, do not appear visually at all, since they are integrated in swivel shafts of the slatted frame which are required anyway and are attached to the frame of the slatted frame.
• the solution is smooth-running, low-noise and largely maintenance-free.
• Two swivel shafts with axis motors and with associated swivel levers which engage the head or foot section are advantageously provided.
• a bed can be adjusted several times by the head and / or foot part can be adjusted independently of one another, in each case in such a way that the head and foot part can each be divided again.
• axle motor is fixed in a rotationally fixed manner to the outer frame of the slatted frame via an axle plate, the pivot shaft being attached to - 3 -
• Plain bearing is rotatably arranged around the engine.
• the axle plate can be equipped with a square retaining bolt into which the motor flange engages with a correspondingly designed square hole. If the motor axis with the windings on it is set in motion, the motor housing is held against rotation and rotation-proof on the outer frame of the slatted frame.
• the invention also provides that the motor axis drives a driver acting on the pivot shaft via a self-locking gear.
• This has the advantage that the adjustable elements of the slatted frame are always securely fixed in their respective position, since the self-locking gear prevents the adjustable elements from sliding back into their starting position.
• the self-locking gear is only unlocked when the adjusting motor is energized, the adjustable elements can then be moved to a different position. As soon as the power supply is interrupted or switched off, the gearbox is automatically locked and the slatted frame is fixed in the desired position.
• the invention also provides in a further advantageous embodiment that the pivot shaft is designed as a square tube and the driver is designed as a square wheel.
• FIG. 1 is a side view of an adjustable slatted base in the starting position
• FIG. 2 is a side view of a slatted base according to FIG. 1 in the raised position of the head and foot area
• Fig. 3 shows a longitudinal section through an integrated on the frame of a slatted frame in a swivel shaft axis motor with a self-locking gear and a drive shaft with square wheel.
• a slatted frame generally designated 1, has an outer frame 2, an inner frame 3, spring elements 4 and spring strips 5 fastened therein.
• An axle plate 6 is fastened to the outer frame 2 with a square retaining bolt 7.
• the axle plate 6 additionally has two slide bearings 8. On these slide bearings 8 there is a square tube 9 as a movable swivel shaft. In this as a square - 5 -
• Tube 9 trained pivot shaft, an axle motor 10 is integrated, which includes a motor housing 11 and a motor axis 12 with windings 13.
• a drive shaft 15 is provided with a driver 16 designed as a square gear 16, which is secured by a stop 17.
• a motor flange 18 On the other side of the axle motor 10 there is a motor flange 18 with a square hole 19 into which the square retaining bolt 7 engages on the axle plate 6.
• the motor axis 12 and the drive shaft 15 are rotatably mounted on ball bearings 20.
• the drive motor 10 is connected via connection cable 21 to a transformer 22 and an associated control, not shown.
• the pivot shafts designed as a square tube 9 are assigned pivot levers 23 which engage the head part 24 or the foot part 25 of the slatted frame 1.
• Fig. 1 shows a slatted base in the starting position. If the axis motors 11 are supplied with voltage by the transformer 22 via the connecting cable 21, the motor rotates. - 6 -
• the head part 23 and / or the foot part 24 are raised as far as desired. As soon as the desired position is reached, the engine 11 is switched off.
• control system By means of a corresponding configuration of the control system, it is possible to raise or lower the head part 24 and the foot part 25 synchronously with one another and also to change their position separately from one another.
• the swivel lever, the insert frame, the swivel shafts and. the like possible. It is only essential that the actual motor is integrated into the swivel shaft as an axis motor to save space and space in order to appear as little as possible in an optically disruptive manner.
