Description

The present invention relates to a Raumspararbett.

Raumsparetten are known from the prior art numerous and in various embodiments. Also known from the prior art devices with which one can transform a sofa into a bed and vice versa.

The present invention relates in particular to a space saving bed such that it can be transformed from a single bed to a double bed and vice versa.

With regard to this type of space saving bed, for example stackable bed frame parts are known. It is also known, superimposed bed frame parts to be hinged together at one longitudinal edge, so that the upper frame part is folded away laterally. In the application, an upper mattress is then removed from the upper bed frame part in the transformation from single to a double bed, the upper bed frame part folded laterally next to the lower bed frame part and placed the mattress removed again on the folded bed frame part. By folding down the upper bed frame part, the arranged in the underlying bed frame part mattress comes to light. This can be a double bed with two mattresses arranged side by side from the single bed. Such a folding bed is as described in the preamble of claim 1 inter alia from the DE 201 11 592 U1 in which the bed frame comprises a first frame part and a second frame part, wherein the first frame part has a first and second mattress receiving device, wherein the first and the second frame part are hinged together about a first axis, wherein the bed frame is arranged that in a first position of the frame parts the mattress receiving devices are arranged one above the other and parallel to each other and in a second position of the frame parts the mattress receiving devices are arranged side by side and parallel to each other and wherein the second mattress receiving device is rotatably connected to the first frame part about the second axis.

However, with respect to this device disadvantageous that first the mattress must be removed and after folding must be placed again or first the frame part first moves and then in a further step, the mattress receiving device can be moved. In addition, the support of the upper bed frame part must be set up for double-sided support of the mattress.

The object of the present invention is therefore to provide a Raumspararbett and / or a corresponding bed frame with or without editions, for example mattresses, which can be transformed from a single bed into a double bed and vice versa, the handling of the transformation is particularly simple, energy-saving and in particular without the removal of a support, in particular mattress, is possible.

This is achieved by a bed frame according to claim 1. The bed frame according to the invention comprises a first frame part and a second frame part, wherein the first frame part has a first mattress receiving device and / or a first receptacle for a first mattress receiving device. A mattress receiving device may in particular comprise or be formed by a slatted frame. A receptacle for a mattress receiving device can be formed for example by appropriate support elements, such as pieces of wood on which, for example, a slatted frame can be placed as a mattress receiving device.

In addition, the second frame part is also designed such that it has a second mattress receiving device and / or a second receptacle for a second mattress receiving direction.

According to the invention, the first and the second frame part are connected to one another such that they can be folded against one another about a first axis. This can be realized for example by appropriate hinges. The bed frame is inventively designed so that the second receptacle and / or the second mattress receiving device rotates about a second axis and / or pivotally connected to the second frame part. In this case, the first and second axes are arranged parallel to one another.

The two parallel axes make it possible, without removing a mattress, to convert the bedframe from a single to a double bed.
In addition, the parallelism of the first and second axis, a particularly energy and energy-saving and injury-susceptible transformation is possible. This in particular by and then, if / is possible to fold with the least possible change in height of the position of the second axis.

With particular advantage, a first support, in particular a mattress, is arranged on the first mattress receiving device and / or a second mattress is arranged on the second mattress receiving device.

Advantageously, the connection between the first frame part and the second frame part can be realized by at least two hinges or be, which allow folding of the second frame part relative to the first frame part. With particular advantage, the first axis is arranged on an edge of the first frame part.

The rotation and / or pivoting about the second axis, for example, by at least one, in particular two ball bearings, and linear ball bearings that allow rotation about the second axis can be realized. In particular, the bed frame on two ball bearings, which allow the rotation and / or pivoting about the second axis and are arranged with a rotation axis on the second axis and in particular in the direction of the second axis an extension of more than 1 cm, in particular more than 3 cm. In particular, the at least two ball bearings are arranged opposite one another on the second frame part. In particular, they are each arranged at a head end and a foot end of the frame part. A head or foot end of a frame part is understood to mean the ends or sides of a frame part which, in particular in the case of rectangular frame parts, represent the short sides.

The frame parts are rectangular when they are rectangular in their cross section parallel to the lying surface, the floor and / or the mattress receiving device.

With particular advantage, the first frame part and the second frame part are connected to each other so that they are designed to be foldable against each other by at least 180 °, in particular by exactly 180 ° about the first axis.

With particular advantage, the first axis is arranged on one edge, in particular on the longitudinal edge, of the first frame part and on one edge, in particular the longitudinal edge of the second frame part.

According to the invention, the second axis intersects the width of the second receptacle and / or the second mattress receiving device and / or the second frame part in the middle. By such an arrangement of the second axis, in particular to one parallel to the longitudinal extent of the mattress receiving device, to the longitudinal extent of the bed surface and / or the longitudinal extent of the frame part and / or the other center with respect to the width of the frame part, the mattress receiving device, the receptacle and / or the bed , a particularly energy-saving and easy transformation can be realized. If, in such an arrangement, the second frame part is folded down from the first frame part, the height of the second axis changes only relatively small, whereby a relatively small expenditure of force is necessary to effect the transformation and reconversion.

In this case, the second axis, in particular arranged parallel to the longitudinal extent of the mattress receiving device, to the longitudinal extent of the lying surface and / or to the longitudinal extent of the frame part.

As a result of the rotation and / or possible rotation about the second axis, the receptacle and / or mattress receiving device and / or mattress of the second frame part can remain unchanged in their orientation in space, while the second frame part is folded or the bed frame and / or Raumspararbett is transformed from a single to a double bed and vice versa.

Accordingly, it is preferred that in a first position of the frame parts, in which the mattress receiving devices, receptacles and / or frame parts are arranged one above the other, and in a second position, in which the frame parts, the mattress receiving devices and / or receptacles are arranged side by side, the orientation the mattress receiving devices and / or recordings and / or resting on these lying surfaces or mattresses, is unchanged. This means that the top of the receptacles, mattress receiving devices and / or mattresses in the first position and the second position are identical. The position of the mattress receiving devices, recordings and / or mattresses is of course not identical, but is changing just in the transformation of the bedstead. This retention of orientation in space in both positions relates to first and second receptacles, first and second mattress receiving devices, and / or first and second mattresses. However, the special feature lies in the fact that this can also be ensured for the second receptacle, second mattress receiving device and / or second mattress. With particular advantage, the orientation of the recordings, mattress receiving devices and / or mattresses during the transfer from the first to the second position is constant and / or it is possible to keep the orientation constant during the transfer.

With particular advantage, the bed frame has a device for automatically rotating the second receptacle and / or the second mattress receiving device about the second axis relative to the second frame part when folding the frame parts relative to each other about the first axis, in particular during the transfer between the first and second position, in particular, such that the second mattress receiving device and / or receptacle maintains its orientation in the space and / or relative to the first mattress receiving device, the first receptacle and / or the first frame part during folding and / or the transfer from the first to the second position and vice versa.

With particular advantage, the bed frame also has at least one locking device for releasably fixing the second receptacle and / or the second mattress receiving device relative to the second frame part, in particular at least in the second position, but advantageously also in the first position.

With particular advantage, the bed frame wheels, especially four wheels. With particular advantage at least two, in particular two wheels can be detected. With particular advantage, the wheels are arranged on the first frame part that they are invisible from the outside. With particular advantage, the lockable wheels and / or two wheels are arranged so that they are covered by a drawer front of the first frame part. In particular, the lockable wheels and / or two wheels are arranged so that they are accessible by moving a drawer front of the first frame part.

A possible embodiment and further advantageous features are to be illustrated purely by way of example and not by way of limitation with reference to the following purely schematic drawings. Showing:

Fig. 1

an inventive bed frame in the state as a single bed;

Fig. 2

the bed frame according to the invention from the preceding figure during the transfer from single to double bed;

Fig. 3

the bed frame according to the invention from the preceding figures during the transfer of Einzelz to double bed showing hidden parts and

Fig. 4

the bed frame according to the invention from the preceding figures in the state as a double bed.

In the figures can be seen a bed frame comprising two frame parts 1, 2. The frame parts 1,2 each have a slatted frame 5, 6 and mattresses 3, 4 placed thereon.

FIG. 1 shows the bed frame in the state as a single bed, in which the second mattress 4 is available. The second frame part 2 is arranged on the first frame part 1. The mattress of the first frame part 1 is hidden.

FIG. 2 shows a condition during the transfer from single to double bed. The second frame part 2 is folded away from the first frame part 1 in the figures to the right. In this case, the first mattress 3 appears.

FIG. 3 also shows a state during the transfer from single to double bed, but in which the second frame part 2 is already folded. In FIG. 3 In addition, some hidden parts are made visible to better explain how it works.

Shown are, for example, two hinges 15, which allow the folding of the second frame part 2 relative to the first frame part 1 about a first axis 7.

To recognize further are two slats 5, 6 on which the mattresses are 3.4 launched. The first slatted frame is 5 arranged in the first frame part 1. The second slatted base 6, is rotatably connected by means of two bearings 9 about a second axis 8 with the second frame part. For releasable detection and prevention of rotation about the second axis 8, the second frame part 2 holes 11. There are further provided two Rigel 10 which can be introduced into the holes for releasable detection and prevention of rotation about the second axis 8, in two relative positions of the second slatted frame 6 to the second frame part 2. Latches 10 and 11 holes together two locking devices.

Is the second frame part 2, starting from a first position in which the second frame part 2 is arranged on the first frame part 1, ie in the state as a single bed, as in Fig ,. 1 shown folded around the first axis 7, the second axis 8 moves slightly upwards and sideways, as in the Figures 2 and 3 shown. The second slatted base 6 can rotate relative to the second frame part 2 about the second axis 8 and thereby maintain its spatial orientation even when a folding of the second frame part 2 about the first axis 7. The second slatted frame 6 can thus be easily moved upwards and slightly laterally by the flaps of the second frame part 2, before it is moved slightly further downwards and further laterally by a further movement of the second frame part 2. In the second position, the second frame part 2 is arranged next to the first frame part 1, ie in the state as a double bed, as in FIG. 4 shown. The second slatted frame 6 is rotated during the transfer by 180 ° relative to the second frame part 2 while maintaining its orientation in space and is therefore in the second position, as in FIG. 4 shown in the first position, as in FIG. 1 shown, identical orientation in space next to the first slatted frame 5. In the first and second positions, the orientation of the second slatted base 6 relative to the second frame part 2 by locking the locking devices 10, 11 are blocked by inserting the latch 10 in holes 11. For transfer between the first and the second position, this locking can be achieved by moving out he bolt 10 from the holes 11 and thus the described relative rotation of the second slatted frame 6 relative to the second frame part 2 are made possible.

The first frame part 1 also has a pull-out drawer 14 and two rollers 12 and two releasably lockable rollers 13. The rollers are rotatably connected to the first frame part 1 about a respective vertical axis. By pulling out the drawer 14, the lockable rollers 13 are accessible so that they can be detected and released. A determination causes prevention of rolling of the rollers. By the rollers 12 and lockable rollers 13, the bed frames can be easily moved in space but also found. This is of particular advantage since single beds and double beds are usually positioned differently in a room. For example, the single bed can save space with its long side, in particular the longitudinal side, where the first axis is 7, placed on a wall and / or even with two of its sides in a corner and can before or after the transfer to the double bed in the Space are rolled into it to facilitate the transfer or facilitate and / or an arrangement of the double bed, for example, with the head on a wall, in particular to the wall on which the long side was previously positioned to allow. A head side is one which adjoins the longitudinal side, in particular at a right angle.
