Foldaway bed

The innovation concerns folding cupboard beds, i.e. beds, which can be hidden in a viewing bar when not in use and for the purpose of a narrow side to be fixed in the closet Pivot axes are folded up on the bed frame so that a when the bed is open, facing underneath the frame swivels into the cabinet level. To relieve the Lifting force5 to swivel the bed on the viewing bench facing away from it Frame end must attack, spring elements are known, which are attached to the closet at one end and to the bed frame at the other end

The disadvantages of such known foldaway beds are mainly due to the spring elements. Easy train and Steel compression springs take up a considerable amount of space in terms of the forces and paths required. You can also use the pan = Do not dampen the movement of the mattress frame so that the frame may open or close with a violent impact. Between The spring coils can pinch the bedding and thereby tear it or make it dirty because of keeping it clean The springs are laborious and difficult to carry out, to dampen the movement and thereby damage the bed and floor to avoid, additional dampers have to be installed, which in turn are expensive, take up space and with their moving parts can stain the bedding.

The task of the innovation is therefore to be seen in the fact that a cabinet bed with spring elements to support the and pivoting is created, the spring elements take up little space and are externally smooth and clean, so that the bedding cannot be soiled by escaping lubricants. It is advantageous if the spring force with a Damping effect occurs paired, so that the pivoting movement takes place slowly and without the risk of violent impacts in the end positions.

The object is achieved according to the invention in that ßasfedern are used as springs. Such gas springs are on known. Your actual spring element is gas under high pressure. At the same time, however, in most cases During the spring movement, hydraulic fluid is pressed through channels that are adjustable in their width, so that the spring movement is damped is. Such a gas spring takes up little space. It is smooth on the outside and therefore easy to keep acidic. Nowhere can Bedding can be pinched. The spring is tight, the hydraulic fluid cannot escape, which could contaminate the bedding.

In a preferred embodiment of the vision bed According to the innovation, a gas spring is used in which a pressure relief spring is installed, which is in the last Phase of the closing movement comes into effect. Such a spring has the advantage that the spring force of the gas just before the Closing of the bed is counteracted by a mechanical spring force so that the closing is completely saft'-before itself, although in the final phase of the pivoting movement of the gas spring from The bed hardly has any force opposing it. Next is a yor ~ part of this special execution form of the bed to see that the initial phase of the opening movement of the Counterforce of the gas spring is largely relieved, so that swiveling the bed out of the cupboard cavity, too

smaller xind less strong person is easily possible. the Relief compression spring also helps to reduce the movement in the initial phase of the swivel movement * caused by the suction in the cabinet cavity difficult to facilitate.

The innovation is explained in detail using an exemplary embodiment shown in the drawing. Show it

Pig. 1 the foldaway bed according to the innovation in the unfolded state;

2 shows the fold-away bed closed; and

3 shows a gas spring with a pressure relief spring in longitudinal section.

In a cavity 10a of a viewing bench 10, a mattress frame 11 is on its side walls in a known manner Articulated bed by means of bearing bolts 12. The frame 11 can be pivoted up over its narrow side remaining in the cavity will. In the swiveled-in position, the facing panel 15 located under the mattress frame is flush with the front plane of the cabinet 10 (see Fig. 2). To support the lifting force when folding the bed and to avoid violent hitting To prevent this, two Gasteleskopf springs are to be found on the end of the mattress frame 11 protruding into the cupboard cavity 10a 14 hinged, which are attached with their second ends via hinge pins 15 on the cabinet interior walls. The piston

Rods 16 of gas springs 14 are whole when the bed is open pushed and, releasing their stored spring energy, step out of the pedal cylinder when the bed is swiveled up until they reach their second end position with the bed closed.

A preferred gas spring used is in Pig. J shown. A telescopic cylinder 20 closed at the top is partially with gas 21 under high pressure, for the other part is filled with a hydraulic fluid 22. In the cylinder 20 is a piston and valve assembly, as a whole denoted by 23, inserted, the piston rod 16 one the lower end of the cylinder forming plug 24 penetrated liquid-tight, so that the piston inadvertently in the cylinder is. The piston is prevented from rotating by a bead 20a in the cylinder tube 20 which extends over the entire stroke of the piston. By turning the piston rod 16 relative to the piston ring 25 before installing the gas spring or during it is possible to increase the width of the passageways 26 for the hydraulic fluid through the piston and valve arrangement 23 to choose, whereby the damping characteristics of the spring den Is adapted to your needs.

The preferred spring now carries, pushed onto the piston rod 16, an additional screw compression spring 27, whose

Length is dimensioned so * that it is only shortly before the piston 25 reaches its lowest position (most extended position of the spring), between these and the piston rod bushing 24 is clamped * so that it counteracts the gas spring, resulting in too violent an impact, favored by the Closing movement of the bed weaker damping of the gas spring., Is prevented. The relief pressure spring also provides support the initial phase of the bed's opening movement and thus helps to overcome the suction that occurs in the cupboard cavity when it is opened arises.
