Bed structure

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a bed structure.

[0002] Several types of bed structures are already known. In an embodiment, there is provided a perimetrical frame which, for example, is made of a metal tubular material and adapted to receive a metal or wire net thereon there is supported the bed mattress.

[0003] This embodiment, however, has the drawback that it is not possible to adjust the resiliency of the net depending on the use requirements.

[0004] Moreover, this bed structure has a comparatively large size, which is disadvantageous for example as the bed is transported.

[0005] Another known bed structure comprises a metal tubular material frame adapted to receive wood strips which are transversely arranged with respect to the longitudinal extension of the bed structure.

[0006] Also in this case it is not possible to change the resilience properties of the wood strips, and, accordingly, it is not possible to fit the bed structure to the user requirements.

[0007] Moreover, since the mentioned wood strips are arranged transversely, they are susceptible to form, as they are bent, a undesirable cradle.

[0008] Even in this case, the bed structure may be transported in a completely assembled condition which, as it should be apparent, is very disadvantageous.

[0009] Moreover, all of the known bed structures have a rather antiaesthetic aspect and, because of this reason, these beds must be completely coated without leaving any parts thereof in an exposed condition.

[0010] The document FR-A-578 941 discloses a bed structure having substantially the features of the pre-characterizing portion of the main claim.

SUMMARY OF THE INVENTION

[0011] Accordingly, the task of the present invention is to provide a new bed structure which affords the possibility of overcoming the above mentioned drawbacks, and which, in particular, can be transported in a disassembled condition to be assembled on the use place, without the need of using particular assembling tools and/or means such as screws and bolts.

[0012] Within the scope of the above task, a main object of the present invention is to provide such a bed structure having a great stiffness in the cross or transversal direction of the bed, while providing a free bending in the bed longitudinal direction and in which, moreover, the bending degree can be adjusted so as to be easily fitted to the weight of the user.

[0013] According to an aspect of the present invention, the above task and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a bed structure having the features of the characterizing portion of the main claim.

[0014] Thus, by the disclosed bed structure, it is possible to transport the bed in a completely disassembled condition and then assemble the bed without using particular tools and affixing means. Moreover, the resiliency properties of the single bars can be fitted to the specific users requirements.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] As is shown in Figure 1, the bed structure according to the invention, which has been overally indicated at the reference number 1 comprises supporting cross members 2, one of which is arranged at the head of the bed, whereas the other cross member is arranged at the other or foot end of the bed.

[0017] The cross members are provided at the top with openings 3 adapted for receiving bar members 4. These bar members 4 connect the two cross members 2 so as to provide a supporting surface for a bed mattress 5.

[0018] As shown, the cross members are advantageously supported by supporting feet 6.

[0019] Also advantageously, the head portion 7 of the bed is made of tubular material.

[0020] Said head portion 7 can be coated or provided with a head rest 8.

[0021] Figure 1 shows a two-place bed 1, but it should be apparent that by the disclosed members it would be also possible to made a single-place bed.

[0022] Figure 2, which is a side view of the subjet bed structure 1, shows that, advantageously, the bed head portion 7 has a L-shape, thereby providing the upright 7a with an elbow configuration.

[0023] The arm 7b of the L-shaped head portion 7 operates as a support and sliding guide for the supporting foot 6 of the cross member 2.

[0024] The cross member 2 provided at the other end of the bed 1 is also coupled to a supporting foot 6.

[0025] As shown, the two cross members 2 are mutually coupled by means of the bar members 4 connected with the cross members 2.

[0026] The two cross members 2, in particular, can be displaced with respect to the bars 4 as shown by the arrows f.

[0027] Thus, the spacing between the two cross members 2 can be changed, thereby it will be possible to adjust and modify the flexure degree of the bar members 4.

[0028] The greater is the distance between the cross members, the greater will be the flexure degree of the bars 3 and vice versa.

[0029] Advantageously, as is shown in Figure 2a, the cross member 2 rests by its foot 6, through a shell shaped support member 9, on the horizontal tubular portions 7b of the cross member 7a.

[0030] If desired, a rigid coupling may be made between the shell member 9 and tubular member 7b by using a locking pin or screw indicated schematically at the reference number 10.

[0031] The foot member 6 of the cross member 2, arranged at the foot end of the bed 2 and shown in Figure 2b also has a tubular shell shape 11 which, advantageously, is coupled to a cylindrical shape member 12, made of rubber, a synthetic material or the like.

[0032] The resilient material cylindrical member 12 is adapted to operate as a cushioning means and an antifriction means.

[0033] Figure 3 is a plan top view of the subject bed structure 1.

[0034] In this view there are clearly shown the bed heat portion 7 and the two cross members 2.

[0035] There is also clearly shown the way in which the cross members 2 receive the longitudinal bars 4 defining the resting surface for a mattress 5.

[0036] As shown herein, said bars 4 define supporting strips which extend with a parallel relationship longitudinally of the bed structure.

[0037] Advantageously, as is shown in Figures 4, 5, 6 and 7, the cross members 2 are provided with upwardly facing openings 3 which are delimited by a circle arc 3a greater than a semicircle, for example of 210°.

[0038] Also advantageously, the openings 3 of the cross members 2 have edge portions which are delimited by beveled configurations 3b.

[0039] This approach prevents the bars 4 from producing noises during the bending thereof and, moreover, provides a rest surface in the case of greatly bent bars 4.

[0040] In this connection it should be apparent that the cross members 2 and the bar members 4 can be made starting from any suitable materials.

[0041] From carried out tests it has been found that a very suitable material for making the cross members 2 is foamed polurethane.

[0042] In fact, this material has high stability and resistance characteristics while providing the possibility of making the cross members 2 by foaming or molding in easily available molds.

[0043] With respect to the making of the bar members 4, it has been found that a very suitable material consists of suitable flexibility and harness wood, synthetic material tubes or metal tubes. For making the bar members 4 can also be advantageously used glass or carbon fibre reinforced materials.

[0044] As shown in Figures 6 and 7, owing to the resiliency of the material used for making the cross members 2 and owing to the specifically designed shape of the seats 3, the bar members 4, of round cross-section, can be coupled by a geometrical type of coupling to the opening 3 formed in the cross members 2 and, advantageously, the bar members 4 can be snap coupled in the seats 3. To this end, the material of the cross members must have a sufficient resiliency.

[0045] The structure formed by the cross members and longitudinal bars have a high stiffness and stability and, moreover, by displacing the cross members 2 with respect to the bar members 4, it is possible to adjust the resiliency of the bars 4.

[0046] Moreover, it is advantageously to close the end portions of the tubular bodies by means of soft resilient material plugs.

[0047] While the invention has been disclosed and illustrated with reference to a specific embodiment thereof it should be apparent that the disclosed embodiment is susceptible to several modifications and variations all of which will come within the spirit and scope of the appended Claims.
