Definitions
- the present invention relates to a bunk bed as defined in the introductory part of claim 1.
- the object of the present invention is to satisfy the needs referred to, which is achieved by the features characteristic of the invention as presented in the claims.
- the bunk bed of the invention comprises at least two bunks placed on top of each other and a suitable supporting structure to keep the bunks steady relative to each other and to the floor.
- the bunks are connected at one end via turnable joints placed at a vertical distance from each other to a vertical wall structure.
- the bunks are connected to each other by means of supporting legs hinged on the bunks in such manner that the bunk bed can be raised and lowered on these four joints between a flat vertical position against the wall structure and a lower horizontal position allowing the use of the bunk bed as such.

Abstract
The invention relates to a bunk bed comprising at least two bunks (1,2) placed on top of each other and a suitable supporting structure (3) to keep the bunks steady relative to each other and to the floor. According to the invention, the bunks are connected at one end via turnable joints to a vertical wall structure (4) and at the other end by means of supporting legs (5) hinged on the bunks in such manner that the bunk bed can be raised and lowered on its joints (6,7, 8,9) between a flat vertical position against the wall structure and a lower horizontal position allowing the use of the bunk bed as such.
Description
- The present invention relates to a bunk bed as defined in the introductory part of claim 1.
- Especially in children's daycare homes and equivalent, there is a great need for simple, safe and easy-to-use beds that occupy as little space as possible and can be quickly taken into use and put out of use as necessary.
- The object of the present invention is to satisfy the needs referred to, which is achieved by the features characteristic of the invention as presented in the claims.
- The bunk bed of the invention comprises at least two bunks placed on top of each other and a suitable supporting structure to keep the bunks steady relative to each other and to the floor. According to the invention, the bunks are connected at one end via turnable joints placed at a vertical distance from each other to a vertical wall structure. At the other end the bunks are connected to each other by means of supporting legs hinged on the bunks in such manner that the bunk bed can be raised and lowered on these four joints between a flat vertical position against the wall structure and a lower horizontal position allowing the use of the bunk bed as such.
- The wall structure preferably consists of the rear wall of a closet, in which the bunk bed in its raised position can be placed and closed up and, by opening the door, it can be lowered into the horizontal bed position.
- The bunks of the bunk bed preferably consist of a rigid bottom plate, e.g. veneer, and sides at least partially surrounding the bottom plate and essentially having some height, extending at least through the length of the longer edges of the bunks.
- The supporting legs provided at one end of the bunk bed preferably constitute a ladder having an upward slope and provided with steps allowing a person to climb up onto the upper bunk.
- The bunks and the joints supporting them in the wall structure are preferably placed at a distance from each other both in the vertical and horizontal directions in such mnanner that the joint supporting the upper bunk lies closer to the wall structure than the joint supporting the lower bunk, the horizontal distance between these joints depending on the height of the sides of the bunks.
- The joints at the other end of the bunk bed, i.e. the joints connecting the supporting legs and the bunks are preferably placed on extensions of the sides, said extensions extending obliquely downwards in the direction of the supporting legs, so that these joints are located below the horizontal planes determined by the bottom surfaces of the corresponding bunks.
- The joint connecting the lower bunk to the wall structure is preferably located at the level of the bottom surface of the lower bunk, so that when the bunk bed is being turned to the upright position, the whole bunk structure will turn over and past this joint, which thus constitutes the extreme limit of the closing motion of the door of the closet.
- The joint connecting the lower bunk to the wall structure is preferably located at a distance from the bunk end facing the wall structure, so that this end of the bunk constitutes a lever, to which a suitable weight reducing means is attached, the other end of said means being connected to the wall structure. In this way, the raising and lowering of the bunk bed are rendered light and easy.
- As compared to previously known techniques, the bunk bed of the invention has the advantages that it is simple in construction and reliable in operation, easy to raise and lower and that it is accommodated in a compact closet, permitting versatile use of many narrow spaces as well as quick changes of use.
- In the following, the invention is described in detail by referring to the attached drawing, in which fig. 1 presents a side view of a bunk bed constructed as provided by the invention, partly sectioned, and fig. 2 presents a perspective view of the bunk bed of fig. 1.
- The illustrated embodiment of the bunk bed of the invention comprises an upper bunk 1, a
lower bunk 2 and a supportingstructure 3 connecting the two bunks. At one end of the bed, the supporting structure consists of awall structure 4 which also constitutes the rear wall of acloset 10, supportig both bunks withturnable joints - At the other end of the bed, the supporting
structure 3 consists of supportinglegs 5 sloping upwards towards thecloset 10 and connected bysteps 13 so that the supporting legs and the steps form a ladder allowing a person to climb up onto the upper bunk 1. - Both
bunks 1, 2 are provided withsides 12 extending through their whole length, of a height preferably exceeding 10 cm. At the end connected to the supportinglegs 5, the sides have a bend and a downwardsloping extension 14 parallel to the supportinglegs 5, so that the joints 8 and 9 connecting thebunks 1,2 with the supportinglegs 5 can be placed in the area of these extensions below the horizontal bottom surfaces of the corresponding bunks. Similarly, thejoints sides 12. Moreover, thejoint 6 of thelower bunk 2 is located at a distance from the bunk end facing thecloset 10 and at the level of the bottom surface of thebunk 2. The result of this arrangement of the joints is an advantageous linkage of the parts, allowing the bunk bed to be easily folded up in a compact space in thecloset 10 and also to be held in its upright position in the closet by the weight reducing means, acompression spring 15, without separate locking devices, so that the bunk bed cannot be turned down e.g. by small children pulling at it from its lower part. This is because, in order to pull out the bed, it must be gripped at as high a position as possible to overcome the counter force of the compression spring, which is impossible if the bed is gripped at a low position, especially because there are e.g. nosteps 13 or similar parts providing an easy handgrip at the lower part of the bunk bed when it is in the closet. Moreover, as substantially the whole bed is made of sturdy veneer, it is firm and rigid in construction and pleasant and light to use. - Although the invention has been described above by referring to one of its preferred structural solutions, various embodiments are possible within the scope of the idea of the invention as defined in the following claims.
