Description

The The invention relates to a folding lounger with a back frame and a foot frame that folds over one Connectors are interconnected and around the folding joints the connector from an extended lying position in a folded position one above the other are foldable, with the back frame in the lying position on footrests and by means of swivel joints fastened struts of a buckling gear held on a base frame is and the folding lounger in the folding position in the base frame by means of of the buckling gear is lowered.

In the patent application DE 10 2007 022 005 A1 is a seat-bed folding frame described in which a complex kinematic chain is provided by four joints to lower the folding frame folded in a base frame can. The locking in the lying position is achieved by expensive linkage, which offer no pinch protection for the fingers.

A generic folding lounger is in the utility model DE 20 2008 002 245 U1 described. In this Faltliege the locking of the reclining position relative to the lowered position of the deck is effected via a clamping mechanism with a rope that is guided in a frame leg and moves a locking bolt.

A Locking the frame parts with each other is not provided.

Both mentioned versions of a folding lounger need a relatively large base frame and have an additional Outrigger pair.

It The object of the invention is a folding lounger with a relative small base frame to reveal, in which the folding mechanism in The lying position is locked so that even with an uneven load of the headboard does not tilt the folding lounger.

Farther the folding mechanism should be designed so that no danger for a pinching of the fingers.

These Tasks are solved with the features of claim 1.

A advantageous embodiment of the invention is in the subclaims described.

The Folding lounger has a back frame and a foot frame, the connected via folding joints of a connector are. When folding the folding lounger, the back frame and the foot frame around the folding joints of the connector an extended lying position in a folding position one above the other folded, with the back frame in the lying position on Footrests and by means of swivel joints attached Striving a buckling gear is held on a base frame. The foot frame is in the lying position with another Foot pair supported. When lifting the foot frame the folding lounger is placed in the folded position and by means of the Knee gear lowered into the base frame.

Around in the lying position a tilting of the folding lounger in a one-sided To prevent strain on the back frame are the folding joints locked to the connector. These are on the back frame a first control pin and at the connector a second control pin mounted in a first and a second guide groove are guided at one end of a wide control plate. The other end of the control plate is hinged to the buckling gear attached. In the lying position now presses the control plate with its guide grooves so on the control bolt that The folding joints are blocked and tilting is avoided.

With a lifting movement of the foot frame are the control bolt released in the guide grooves on the back frame is allowed up to a locked end position and the folding of the foot frame on the back frame is allowed up to a locked end position.

at another lifting movement, the folded feet and back frame the folding lounger by means of the buckling gear lowered into the base frame.

The Guide plate, the connecting plate and the control plate are designed as wide sheets. They are close to the Foot frame, the back frame and the connector guided, so that no columns with moving parts result in which fingers can be clamped.

Based The figures become the control and locking mechanism when folding the folding lounger explained in more detail. Showing:

1 the folding lounger in extended lying position;

2 the folding lounger with slightly raised foot frame;

3 the folding lounger with further raised foot frame;

4 the folding lounger with folded on the back frame foot frame;

5 the folding lounger lowered in the base frame.

The Movements for folding are indicated by arrows.

In 1 is the folding lounger with the foot frame 1 , the connector 5 and the back frame 8th in the extended lying position with resting mattress 11 shown in side view. The back frame 8th is with the connector 5 over the folding joint 33 connected and on the base frame 10 with the buckling gear 7 and the second foot 9 held. The foot frame 1 is with the connector 5 over the folding joint 23 connected and resting on the first foot 2 from.

In a kinematic chain over the guide plate 3 , the connecting plate 4 and the tax billboard 5 is the first foot 2 with the buckling gear 7 connected.

On the back frame 8th is a first control bolt 29 and on the connector 5 is a second control bolt 27 attached in the first and second guide groove 19 . 20 at the connector end of the control plate 6 are guided. The other end of the control plate 6 is in the joint 34 at the buckling gear 7 attached.

The first guide groove 20 is designed as a linear guideway and the first control pin 29 beats in the lying position at the outer end 26 the guideway. The second guide groove 19 in the tax book 6 is formed in L-shape and the second control pin 27 beats in the lying position at the top 32 the long leg of the L-shape. In this way, the folding joints are locked in the lying position and at a load according to arrow X, the folding table does not tilt.

If now the foot frame 1 according to 2 and arrow A is raised, the connector also rises 5 and the tax billboard 6 is about the first control bolt 27 in the first guide groove 20 with raised. The second control bolt 29 moves in the L-shaped guide groove 19 downward.

In the further folding movement according to 3 and arrow A hits the first guide pin 27 at the inner end 28 the guideway and the second guide pin 29 hits at the break point 30 the L-shaped guide groove 19 at. The foot frame 1 is with the first foot 2 over the joint 21 connected. The lifting movement according to arrow A when folding the folding lounger is in the kinematic chain with the guide plate 3 that at the first foot 2 over the joint 22 and the connector 5 over the joint 24 hinged, at first foot 2 transfer. The pivoting movement of the first foot 2 according to arrow B is over the connecting plate 4 at the second control pin 29 and on the guide plate 3 with the joint 25 attached, controlled.

In a further folding movement of the foot frame 1 according to arrow C in 4 becomes the foot frame 1 completely over the head frame 8th worked.

To reach the lowered position, the folded folding lounger according to arrow D is further raised. Then the second control pin moves 29 to the end 31 the short leg of the L-shaped guide groove 19 , Above it is the tax billet 6 so far released that the buckling gear 7 can buckle and the folding lounger in the base frame 10 lowers.
