The present invention relates to a bedstead.
Bedsteads usually have a box shape and form on the upper side thereof a support surface for a mattress or the sleeper himself. Fixed bedsteads are known, as they are mainly used in houses or apartments. However, collapsible or folding beds are also known, in which the bedsteads have their maximum size only for sleeping and otherwise take up less space in a folded state. Such folding beds are of particular interest for the camping sector, but not only for this purpose, as they require less space during the day. It must then be taken into account, that in many countries, a maximum load weight is prescribed for vehicles or caravans, which has a limiting effect on the components to be taken along.
The object on which the invention is based is to propose a foldable or collapsible bedstead which is suitable for use in the camping sector.
The invention achieves the object by means of a bedstead, comprising a base body and four frame elements, wherein the four frame elements are arranged in pairs on opposite sides of the base body, wherein the four frame elements each have a fastened front side and a free front side, and wherein the fastened front sides of the four frame elements are connected to the base body via joints and are designed to be movable separately from each other.
In the bedstead according to the invention, four frame elements are fastened to a base body. As the fastening is realized via joints, it is possible to move the frame elements relative to and separately from each other in relation to the base body. In particular, they can thus be folded out or deployed. The four frame elements preferably form in pairs the two long sides of the unfolded bedstead and of the bed thus formed. The four frame elements are fastened to two opposite sides of the base body, also in pairs—but in other combinations. In the unfolded state, two frame elements thus form the head side and two frame elements form the foot side of the bed.
The frame elements—which are preferably designed in a rod shape—each have two front sides: a fastened front side and a free front side. The frame elements are connected to the base body via the fastened front side.
In one embodiment, the frame elements are connected to leg elements at their free front sides and/or are adapted to be reversibly connected thereto. The extension of such leg elements in the unfolded state of the bedstead preferably runs perpendicular to a longitudinal axis of the associated frame elements. In one embodiment, the leg elements are connected to the frame elements via joints. In an alternative embodiment, the leg elements are rigidly connected to the frame elements. In one embodiment, there is a rigid connection between one part of the combinations of a frame element and the associated leg element, and the other part of the combinations respectively has a joint between the frame element and the leg element. In the unfolded state, the frame elements thus each rest on the floor via two components: with the base body on the fastened front side and with the leg element on the free front side. Alternatively, the leg elements are reversibly connected to the frame elements, for example via a type of detachable screw connection, and can thus be attached and removed again.
To obtain a resting surface for the sleeper, at least one separated support element is provided in one embodiment. The at least one support element is located between the two long sides of the bed and between the two frame elements which are arranged on the same side of the base body. The support element thus bridges the free space between the two adjacent frame elements. Preferably, a plurality of support elements is provided.
The two frame elements of the aforementioned embodiment, between which the support element is located, are indirectly connected to each other only via the at least one support element—or in one embodiment only via a plurality of support elements. In particular, there is therefore no front-side bridging element connecting the free front sides of the two frame elements to each other. In other words, the unfolded bedstead is respectively open at the head and at the foot in relation to the frame formed by the frame elements. Overall, the unfolded frame thus has the shape of the capital letter H. This is in contrast, for example, to the shape of the—angular—capital letter O in a fixed bed.
One embodiment consists in that the base body encompasses an interior space and in that the at least one support element and the interior space are designed and adapted to each other such that the interior space receives the at least one support element. According to this embodiment, if the bed is not needed, the at least one support element can be stowed in the base body. This reduces the space required for the folded sate of the bedstead. In one embodiment, several support elements are provided which preferably can all be accommodated in the interior space.
According to a further embodiment, two of the four frame elements are indirectly connected to each other via a movable crossbar. For the connected state, the crossbar is preferably located close to the free front sides of the frame elements and thus forms a reversible closure. In the folded state of the bedstead, the crossbar is preferably located close to or even within the base body.
In one embodiment, the crossbar is movably mounted between the two frame elements. The crossbar can thus preferably be displaced along the frame elements. In one embodiment, a rolling mounting is provided.
In one embodiment, a mattress is provided with slatted frames which can be placed onto the bedstead.
According to one embodiment, the joints are arranged on an upper side of the base body. Preferably, the base body is designed such that it can rest on a floor on the (lower) side opposite the upper side. In one embodiment, this involves that a height of the base body determines a height of a section of the unfolded bedstead.
In a further embodiment, the opposite sides of the base body on which the four frame elements are arranged in pairs, are long sides of the base body. The base body preferably has an elongated extension, the longer side being perpendicular to the longitudinal axis of the unfolded bedstead.
According to one embodiment, the base body has a substantially cuboid shape.
One embodiment provides that the four frame elements are variable in length. In this embodiment, the frame elements can thus first be rotated away from the base body via the joints to then be brought to a desired length. For example, a tube-in-tube design of the frame elements allows such a change in length.
According to an alternative or additional embodiment, at least one leg element is variable in length. In one embodiment, a plurality of leg elements is variable in length. The height of the head or foot side of the bed can be adjusted by a variability of length. In one embodiment, the joints between the base body and the frame elements allow the head and/or foot side of the unfolded bedstead to have an incline relative to the base body.
One embodiment provides that at least one leg element has a foot element at its end facing away from the frame element. The foot element is for example designed to have a plug shape or has a certain elasticity.
One embodiment provides that the at least one support element is adapted to be reversibly fastened to at least one frame element via a combination of at least one recess and a spike. The spike is preferably perpendicular to a relative direction of movement between the support element and the frame element. In the unfolded state of the bedstead, the spike projects through the recess and thus establishes a reversible connection. This serves the purpose of securely connecting the components of the unfolded bedstead to each other.
In an alternative or additional embodiment, at least one frame element encompasses a receiving space in the manner of a clamp, and the support element is adapted to be inserted into the receiving space via a height-reduced side area. In this embodiment, the at least one support element is inserted into a kind of guiding rail of the frame element at a side area the height of which is reduced compared to at least one further section of the support element. Accordingly, the receiving space is preferably open in the direction of the support element.
In one embodiment, two adjacent frame elements—in the unfolded state—each have a receiving space, the receiving spaces being each open towards each other. The at least one support element has a height reduction on both opposite side areas, via which it is inserted into the receiving spaces of the frame elements in the unfolded state of the bedstead.
In one embodiment, a plurality of support elements is provided, and at least some of the support elements are reversibly connected to each other. Due to the fact that the support elements are at least partially reversibly connected to each other, a stability in the longitudinal direction of the unfolded bedstead is increased. The connection is made using a tongue and groove connection, for example.
In an alternative or additional embodiment, a plurality of support elements is also present, wherein at least some of the support elements abut against each other at the ends. In this embodiment, there is no connection between one part of the support elements, rather, support elements only abut against each other. In one embodiment, the support elements concerned are located at the height of the base body.
One embodiment provides that the at least one support element is at least partially made of wood. The wood preferably has a certain elasticity so that the effect of a mattress is generated or reinforced.
In an additional or alternative embodiment, the base body is made of a metal.
In a further additional or alternative embodiment, the frame elements are made of metal.
In more detail, there are a large number of possibilities of designing and further developing the bedstead according to the invention. To this end, reference is made to the description below of example embodiments in conjunction with the drawing, in which:
A cuboid base body 1 is located in the middle of the bed. Four frame elements 2 are fastened on the upper side 11 on the long sides 10 thereof. The connection is realized via joints 4 so that the frame elements 2 can be pivoted. In the folded state, the frame elements 2 are positioned directly on the long sides of the base body 1.
The four frame elements 2 form twice two pairs. On the one hand, these are the two pairs which are each connected to the same long side 10 of the base body 1 and thus form the head or foot side of the bed. In the unfolded state, these frame elements 2 are arranged substantially parallel to each other. On the other hand, these are the two pairs the members of which are each aligned one behind the other and thus form the long sides of the bed. These frame elements 2 are each connected to the same narrow side of the base body 1.
The frame elements 2 are here designed in a rod shape and are for example variable in length. They have a fastened front side 20 and a free front side 21. The fastened front side 20 is respectively attached to the base body 1 via a joint 4, so that the respective frame element 2 is freely movable with respect to the base body 1.
In the illustrated embodiment, the free front sides 21 are each connected to a leg element 5 via a joint 52. In an alternative embodiment—not illustrated—at least one leg element 5 is rigidly connected to the associated free front side 21. The free front side 21 thus rests on this leg element 5. For a good rest on the floor, the leg elements 5 in the illustrated embodiment each have a foot element 51 at the end 50 which faces away from the free front side 21. The leg elements 5 are here also designed in a rod shape and also allow a change in length and thus a change in height with respect to the position of the respective free front side 21. The variability in length is realized, for example, by a rod-in-rod arrangement with an adjustable fixing device.
This overall results in an H-shape from the base body 1 and the four frame elements 2, which are respectively open at the head or foot end.
Support elements 3 which here have the shape of a board are located between the frame elements 2. For reasons of clarity, only one support element 3 is indicated here. The support elements 3 connect those frame elements 2 indirectly with each other, which are respectively connected to the same long side 10 of the base body 1 and which are here arranged parallel to each other. The support elements 3 are arranged one behind the other along the longitudinal axis of the unfolded bed.
The dimensioning of the support elements 3 is preferably such that they have enough space in the interior space 12 enclosed by the base body 1. In the folded state of the bedstead, this thus results in that the support elements 3 are inserted into the base body 1, while the frame elements 2 and the leg elements 5 rest close to the base body 1. Therefore, little space is required.
The support element 3 partially shown here has a recess 30, and the frame element 2 has a spike 22 which projects upwards here. In the assembled state—outlined here—the spike 22 is located in the recess 30 of the support element 3 and thus fixes it against a displacement.
Four frame elements 2 are visible, which are each connected to the base body 1 via a joint 4 and can be moved separately from each other. Each frame element 2 rests on a leg element 5 via its free front side 21. In the embodiment shown, the four leg elements 5 are each reversibly connected to the frame elements 2 and can thus be removed again.
A crossbar 6 is located between one respective pair of frame elements 2 and is mounted in a rolling manner between the two frame elements 2. For the illustrated unfolded state, the crossbeam 6 is respectively pushed forward to form the reversible closure. In the folded state, the crossbeam 6 is located so close to the base body 1, for example in a recessed step, that the frame elements 2 can be pivoted back individually towards the base body 1.
