Description

Sofa that can be converted into a lounger

The invention relates to a convertible into a couch Sofa, consisting of a frame, a hop, a back and a seat part, which are upholstered, souiie one in the rock roughly like a drawer the latter frame part that can be pulled out to a limited extent at the front, and the back and seat parts by means of accessories, respectively Laterally arranged and on the pull-out frame part held Uierenschwenkekette to the adjustment direction of the pull-out frame part right-angled axes limited uerschwenkbar arranged and each other are articulated and the head part hinged to the sofa frame in the sitting position standing approximately upright behind the upright back part is arranged, while when converting in the lying position the Hopf «, the back and the seat part is arranged one behind the other at approximately the same level will.

In a sofa of this type known from practice is the head part on the one hand near its free end on a hinge arranged on the frame at about seat height

axis articulated, on the other hand articulated with the back part connected, so that when converting the sofa from the sitting position, with the headboard erected behind the dsm The back part is arranged to run approximately parallel to this, in the lying position of the head part with its on Rückentsil articulated end part around the articulation axis fixed to the frame after worn until it pivots approximately into the horizontal.

Here are to achieve the longest possible lying surface If the seat length is relatively short, about the length of the thigh and the seat height is normal, the back and head sections formed much longer than the seat part.

With a normal seat height, this leads to a relatively large height of the back part pivoted into the sitting position.

With the invention is now for a sofa of the type specified in the preamble of claim 1 while maintaining a relatively long lying surface and a relatively short seat length with a low seat height as low as possible Aimed at the height of the erect back section with a low frame depth.

The solution to this problem is characterized in that a) the head part is articulated to the frame by means of two four-link chains arranged on each side,

the wrist chain swing arms on the one hand Frame are hinged at a distance one above the other, the upper rocker arm a shorter length than the lower rocker arm has, the rockers on the other hand on the head part forming the coupling in the longitudinal extent of the bed one behind the other and are articulated at a distance from one another, furthermore the articulation axis fixed to the frame for the upper rocker arm above the seat part is arranged, while the frame axis for the lower rocker with such a distance is arranged from the base side of the sofa frame that in the sitting position of the free end part of the head part up and close to the base of the sofa frame

b) on the pull-out frame, one on the back part that can be attacked Driver is arranged. £

As a result of these measures, when the sofa is converted from the lying position to the sitting position, those held on the headboard move Articulation axes for the Schulingen in the direction of the rear wall of the frame, which was influenced by the back part The foot part is pivoted upwards with its free end part and adjusted behind the back part which is slightly inclined to the rear will.

This allows the headboard to achieve a long Make the lying surface much longer than the back part, thereby maintaining a normal seat height and a small seat length, as before, is a substantial one lower overall height of the sofa than previously achievable.

In addition, it is also ensured that when converting de? Süfas from the sitting position to the lying position of the Hop part / om the back part is inevitably taken along. Even when changing the sofa from the lying position to the The sitting position is influenced by the hop part and the back part inevitably taken away.

üOther, technically favorable and for the task solution Advantageous embodiments of the above-described subject are disclosed in claims 2 to 7.

An embodiment of the invention is shown in the drawings and is described in more detail below. Show it:

Fig. 2 also in the lying position.

This sofa consists of a frame 1 with frame side bolsters 2, a head part 3, a back part k and a seat part 5, the parts k and 5 being hinged to one another and held by means of Uier pivot chains 6 on a frame part 7 sa that can be pulled forward from the frame 1 that the back part it is thrown down at the same level as the seat part 5 when the frame part 7 is pulled out of the frame 1 forwards.

The head part 3 is by means of two, each side of the Head part 3 of the Uierkette 8 provided on the frame 1 is supported. The Uierverbindkette ß each include one on a frame side cheek 2 attached frame part 9, two hinged to the latter rockers 10 and 11 and a coupling 12 attached to the head part 3.

The pivot axes 13 and 1 ^ for the rockers 10 and 11 are arranged vertically one above the other on the frame 9. Their distance from each other is slightly larger than that Length of the short link 11. The lower link 10 is longer than the upper link 11.

The coupling 12 has about a third of the rocker 11 corresponding length.

On the frame part 7 are zuaei laterally arranged upright Head part 3 bypassable Seitenuiangen 5 provided on the rear end parts of which a driver 16 effective on the hop part 3 is attached.

The driver 1G is more articulated than on the Seitenuangen 15 U-shaped bracket formed, the web 17 with a on the back of the head part 3 arranged catch hooks 1B corresponds and its legs 19 aiming downward from the web 17 at the Seitenuangen 15 of the pull-out

borrowed the seat part 5 to capture and pull out to the front. The frame part 7 is inevitably taken along to the front and at the same time the seat and back part in the Swiveled lying position, while pulling out the Frame part 7 from the sofa frame 1 inevitably rests on the web 17 on the approach ramps 2D and is supported by this inevitably introduced into dis catch hook, so that when further Pulling out the frame part 7 also entrained the hop part 3 and pivoted into an approximately horizontal position according to FIG. The legs 19 pivot in their rearward direction End position.

For converting the sofa from the lying position to the sitting position also only the seat part is to be grasped and used To move the rear wall of the frame 1 towards. Swinging around the seat and the back part inevitably into the Sitting position. However, before that position has been reached, the head part is influenced in its own by the back part upright position has been pivoted.

Reached when inserting the Gestsllteiles 7 into the Sofa frame 1 standing in its rear end position bracket the frame rear wall, it is influenced by this Swiveled back into the upright, space-saving position.

All new ones disclosed in the description and / or drawing Individual and combination features are considered essential to the invention viewed.
