Description

The invention relates to a convertible into a bed seating with two supplementary cushions and a seat cushion to form a bed.

In known furniture of this type supported on the ground roles are required, which carry the bed parts in particular in the conversion. Such roles may vary depending on the nature of the soil, z.β. on carpets that disturb the transformation.

The invention has set itself the goal of creating a furniture in which a conversion from the sitting in the lying position and vice versa is possible without the use of supported on the ground roles.

This is achieved by the fact that the pivot point of an angle lever is arranged on the furniture frame and the shorter arm of this angle lever on a supplementary cushion, the longer arm acts centrally on the second supplementary cushion and the end of the seat cushion, further that the pivot point of a second angle lever is also arranged on the furniture frame, the second bell crank having two longer arms, one of which engages the seat pad, the second engages the second pad, the shorter arm engaging the first pad.

An inventive furniture can be brought with a handle from the sitting in the lying position and vice versa, without roles for leadership on the ground are necessary.

In the following, the invention will be described in detail with reference to an embodiment shown in the drawings, without being limited to this example. Showing:

• Fig. 1 in perspective view of an inventive furniture in the lying position;
• Fig. 2 also a perspective view of the furniture in the sitting position;
• Fig. 3 a side view of the furniture in the lying position;
• Fig. 4 a side view of the furniture in the lying position;
• Fig. 5 a side view of the furniture during the conversion and
• Fig. 6 a view of the essential fittings parts.

According to the drawings, two supplementary cushions 5 ', 5 "and a seat cushion 5"' are arranged in a furniture frame with a fastening part 1. On the fastening part 1 of the furniture frame, the pivot point of an angle lever 7 is arranged. The shorter arm of this angle lever 7 engages the supplementary cushion 5 ', whereas the longer arm at the attachment part 3 in the middle of the second supplementary cushion 5 "and ends at the attachment part 2 on the seat cushion 5"' attacks.

The fulcrum of a second angle lever 6 is also arranged on the furniture frame or on its attachment part 1. This second angle lever 6 has two longer arms, one of which engages the mounting pad 2 on the seat cushion 5 "', the second fastening part 3 on the second supplementary cushion 5". The shorter arm of the second angle lever 6 engages the first supplementary cushion 5 '.

As in particular from the FIGS. 4 and 6 , But also from the other figures can be seen, the two angle levers 6 and 7 touch each other by means of lugs 14 in both end positions.

A foot 10 supports the supplementary cushion 5 "in the seated position on the ground. In the supporting position, the foot 10 is controlled by a handlebar 11.

On supplementary pad 5 'is a support roller 12 is arranged, which supports the supplementary cushion in the sitting position on the ground.

A spring 9 acts on the shorter arm of the angle lever 7 and supports the conversion of the lying in the sitting position of the furniture. In the drawing is a Tension spring shown, but it is also the use of a gas spring or a Tursionstabes possible.
