Fitting for height adjustment of a headboard opposite and with a back part of a slatted frame

The invention relates to a fitting for pivoting the height of a head part relative to and with a back part of a mattress frame, in particular a slatted frame, according to the preamble of claim 1.

Such a fitting is known from DE-GM 297 14 299 and has proven itself in practice.

Based on this prior art, it is the object of the invention to create an improved fitting of this type which enables safe vertical pivoting in a simple and cost-effective manner and forms a rigid, non-rattling structural unit in the pivoted-up position of the head and back sections.

This object is achieved according to the invention by the characterizing features of claim 1.

The subsequent subclaims contain design features which represent advantageous and beneficial further developments in the solution of the task.

The fitting according to the invention consists of two fitting parts that are pivotably coupled to one another, a pivot limiter of the two fitting parts against one another and a bolt that is advantageously positioned horizontally, can be moved in a horizontal plane and can be easily pivoted away, which on the one hand results in an advance pivoting of the head part fitting part and then a rigid coupling between the two fitting parts for the joint vertical pivoting. The coupling is ensured by the one stop pin in an arcuate slot and the bolt on the latch side in a locking lug of the second slot that slidably accommodates the latch bolt, as this advantageously creates a two-point, rigid connection of the two fitting parts that does not allow any movement against one another during the upward pivoting and also in the upwardly pivoted position and thus results in a solid and non-rattling structural unit.

An embodiment of the invention is explained in more detail below using the drawing. It shows:

Fig. 1 is a side view of the two mutually and

Height-adjustable fittings for a back and a head section of a mattress frame (slatted frame) in the flat starting position,

Fig. 2 a side view of the fitting with the A head fitting part pivoted upwards and the bolt displaced longitudinally,

Fig. 3 a side view of the two fitting parts locked against each other by the latch in a further upwardly pivoted position.

The fitting for pivoting the height of a head part (1) relative to and with a back part (2) of a slatted frame has a fitting part (3, 4) that can be fixed to the back part (2) and a fitting part (3, 4) that can be fixed to the head part (1) and a pivot axis (5) that connects both fitting parts (3, 4), as well as a pivot limit for the head part (1) relative to the back part (2) that is arranged on both fitting parts (3, 4) at a distance of φ from the pivot axis (5) and is formed by an elongated hole (6) bent at a distance around the pivot axis (5) and a stop pin (7). Both fitting parts (3, 4) are coupled to one another by a latch (8) that locks the head part (1) pivoted relative to the back part (2) in the raised back part position and releases the locking when the back part is lowered.

The latch (8) is attached to the back-side fitting part (2) in a horizontal direction with a bolt (9) in a horizontal, straight slot (10) and on a

-A-

The support bracket (11) assigned to the fitting part (3) is supported for the vertical pivoting of the headboard-side fitting part (1).

To lock both fitting parts (3, 4) for the joint height adjustment, the latch (8) runs on the support bracket (11) with the bolt (9) up to the end of the slot on the pivot axis side and pivots into a sloping locking groove (10a) on the end of the slot (10).

The horizontal bolt (8) is connected to the headboard-side fitting (4) with a length end facing the fitting (4) via the stop pin (7) and engages with this stop pin (7) through the arched pivot limiting slot (6) cut out in the backboard-side fitting (4). The bolt (9) engaging in the slot (10) of the backboard-side fitting (3) is attached to the bolt (8) at a distance from the stop pin (7), and is preferably formed by a rivet.

The latch (8) has a molded, downward-facing nose (8a) at the free length end, with which it rests on the horizontal leg (lla) of the support angle (11).

The bolt (9) of the latch (8) is located between the stop pin (7) and the nose (Ha).

The support bracket (11) is attached to the bed frame and the horizontal angle leg (Ha) grips under the fitting part (3).

The latch (8) is formed by a latch plate in an elongated web shape with rounded ends.

The two fitting parts (3, 4) are formed by angles with vertical tabs at the adjacent length end.

At the free length end of the headboard-side fitting part (4) is hinged a pivot lever (12) to which a single or multi-part push lever (13) driven by an actuator (not shown) is articulated for adjusting the headboard and backrest; the push lever (13) is rigidly attached at its other end about an axis that can be rotated by the drive, so that when the axis is rotated the push lever (13) pivots.

In Fig. 1, the back part (2) with head part (1) is lowered into the horizontal position and the latch (8) rests in the horizontal position with its nose (8a) on the angle leg (lla) of the support angle (11).

From the drive, the fitting part (4) with the head part (1) is first pivoted upwards by a certain angle, preferably 30°, via the levers (12, 13), whereby the stop pin (7) of the fitting part (4) moves from one end to the other in the curved slot (6) and the stop pin (7) takes the bolt (8) with it in the horizontal displacement direction (F), namely into the position shown in Fig. 2. Now the bolt (8) with its nose (8a) at the end of the angle leg (Ha) is still resting on it and the bolt (9) is still above and just before the locking groove (10a). When the fitting part (4) is pivoted further in height, the fitting part (3) with the slot (10) pivots upwards and the locking groove (10a) then grips the bolt (9) - the locking groove (10a) takes the

Bolt (9a) on; the latch (8) rests on the end of the angle leg (11a) with its nose (8a) on the same and the head part (1) is pivoted up by 30°. Since the stop pin (7) has now struck at the end of the slot (6) and the bolt (9) has engaged in the locking groove (10a), a rigid coupling between the two fitting parts (3, 4) is established.

When swiveling up further, both fitting parts (3, 4) and thus the head and back sections (1, 2) are swiveled up together up to a swivel angle of about 60°, as shown in Fig. 3 whereby the fitting part (3) lifts upwards from the support angle (11).

In the coupled position, the two fitting parts (3, 4) form a rigid, non-rattling structural unit when swiveled up and in the swiveled up position.

When the fitting parts (3, 4) are lowered, the fitting part (3) rests on the angle leg (Ha) of the support angle (11) and the bolt (9) is pushed up out of the locking groove (10a) as the latch (8) also rests on the angle leg (Ha). The fitting part (4) can now swing freely relative to the fitting part and the latch (8) is pushed back in the opposite direction to the displacement (F) that occurred when it was swung up.
