Definitions

• Mattresses which consist of modular elements arranged transversely in a cover.
• a mattress of this type described in Swiss patent No (patent application No 9,100 / 79) comprises modular elements of at least two different types distinguished by their degrees of hardness.
• the modular elements of these mattresses are generally interconnected, to ensure good performance of the assembly, by belts or the like.
• This mattress is characterized by the fact that it comprises means making it possible to removably connect each modular element to the adjacent modular elements.
• said connecting means will be directly incorporated into the modular elements.
• Figure 1 is a plan view
• Figure 2 is a sectional view through line II-II of Figure 1
• Figures 3 and 4 are similar views, at the end, of the two ends of the mattress, the cover being removed
• Figure 5 is a median vertical sectional view, on a larger scale, of a modular elements
• Figure 5 is a median horizontal sectional view, corresponding to Figure 5 of the same element
• Figure 7 is a view similar to Figure 5 illustrating the connection between two elements.
• Figure 8 is a view similar to Figure 7 showing how a modular element is articulated to its adjacent elements.
• Figures 9 and 10 are views corresponding to Figure 6 the second illustrating the coupling of the connecting means;
• Figure 11 is a view similar to Figure 7 illustrating the operation of uncoupling two elements.
• the mattress shown is constituted by a cover 11, made of flexible canvas, and by a series of modular elements 12, made of latex foam, arranged transversely side by side in this cover.
• These modular elements 12 are of three different types, distinguished by their hardness. Their distribution takes into account in particular the weight and the morphology of the user. Other factors can also intervene to determine this distribution, for example to prevent deformations of the spine or, if necessary, to correct them.
• the modular elements 12 are removably connected to each other by coupling pieces 30. ( Figures 5 and 6) of molded plastic, for example nylon.
• These parts 30, three by modular element 12, are each formed by a perforated flexible plate 31, by a male coupling member 32 and by a female coupling member 33.
• the plates 31 are embedded in the mass of latex and are 'extend in the horizontal horizontal plane of the corresponding modular element and the coupling members 32 and 33 protrude on the two opposite faces of this element.
• Each male member 32 is constituted by a rigid axis 34 and each female member 33 by your stirrup 35, the two branches 36 of which can be spaced apart from one another.
• Each of these branches 36 has two converging walls (37)
• the coupling members can pivot (fig. 8) around the axes 34 which allows the elements to take the inclination wanted when a person is lying on the mattress.
• the shells 39 have at their lower part a boss 40 which does not allow the axes 34 to escape from the bottom. These bosses eliminating the risk of an accidental uncoupling between two adjacent modular elements if, as a result of abnormal deformation of these elements, one or more axes 34 manage to come out of their housings.
• the main advantage of the mattress described lies in the fact that to change one or more modular elements 12, for example to adapt the mattress to an evolution in the morphology of the person using it, it suffices to decouple the element or elements concerned by this change.
• the invention does not only apply to mattresses whose modular elements are of several different types, but also to those which have only one type of element. In fact, in these mattresses it may be necessary to replace worn elements with new ones.
