The present invention refers to a bedspring or similar sprung base for supporting persons, which contains a fluid element, in particular water, and is provided for effectively, safely, reliably, hygienically and ergonomically supporting people lying thereupon.

From US-A_4292701 is known a people-supporting base assembly with fluid element, in particolar water, comprising at least a fluid-filled mattress, capable of being filled with liquid medium through a filler fitting and being adapted onto support frameworks or beds and/or settees, or onto the floor, and an enhanced-flexibility mattress laid below said fluid-filled mattress, and also comprising at least another support structure that is adapted to be placed below said fluid-filled mattress and to be covered by the enhanced-flexibility mattress, said further support structure being provided with elastic means (i.e. springs) adapted to sustain people in a springly and anatomically correct manner by adapting the surface conformation of said structure in accordance with the actual weight of and the posture taken from time to time by the person (s) lying thereupon.

It is the general object of the present invention to provide an innovative kind of support bed, sofa or similar base with fluid medium, which is realized in a manner different than that disclosed by US-A-4,292,701, which enables people to be supported in an effective, reliable, safe, hygienic and ergonomic manner thereupon.

According to the present invention, the support base of the above-indicated kind incorporating the characteristics as recited and defined below with particular reference to the appended claims.

The invention will anyway be more readily understood from the description that is given below by way of non-limiting example with reference to the accompanying drawings, in which:

Illustrated schematically in the above-listed Figures is a bed or similar people-support base filled with a fluid medium, such as in particular water, according to the present invention, which is adapted to support people in an effective, safe, hygienic and ergonomic manner.

As can be seen in the Figures, this support base 5 is substantially comprised of at least two mutually superposable component parts, i.e. an underlying component parts consisting of a traditional water mattress 6, or a similar mattress filled with any other fluid medium, comprised of a case 7 made of an appropriate material, such as vinyl, fluid-tightly sealed against the outside, so as to prevent water from undesirably leaking or seeping therefrom, and enclosed by an outer support structure of a rigid material (not shown), and an overlying support structure 8, in which there is incorporated a plurality of moving, vertically displacing support members 9, and which is intended to support one or more persons, under interposition of a mattress 10 that can be laid upon the outer top surface of the same support structure for enhanced flexibility.

The water-containing case 7 is provided in a generally quadrangular shape (although this is not a pre-requisite, since other shapes are possible, as well) and is sized so as to be capable of adapting to and being removably placed on bedsteads or similar bed and/or sofa support frameworks (not shown), or even directly on the floor, and is configured to include one or more inner chambers (not shown), which communicate with each other and are adapted to be filled - through a filling orifice 11 with related sealing filler cap provided on a side - with pre-determined amounts of water as required to ensure an effective support for people lying down upon this support base.

Figures 1 through to 4 illustrate a first embodiment of the support base according to the present invention; in particular, in Figure 1 there can be noticed that the support base itself is comprised of the water mattress 6, the support structure 8, which can be of the elastic or non-elastic type and has the same shape and size as the water mattress 6 so as to be able to be placed upon the latter, and the overlying enhanced-flexibility mattress 10. In particular, the support structure 8 is substantially comprised of an outer covering 12 of a suitable material, which is stuffed internally with flexible and transpiring semi-rigid material, such as preferably polyurethane foam, and encloses the afore-cited moving, vertically displacing support members 9 that are provided in a juxtaposed, i.e. side-by-side arrangement, slightly spaced from each other, in the longitudinal and lateral direction of the support structure 8. Each such moving support member 9 is preferably made of plastics and substantially comprises a short rectilinear and equally long vertical stem 13, whose length is shorter than the height of the support structure 8, and whose ends join both to a respective mushroom-shaped, i.e. fungiform head 14 and 15 having a hemispherical outline and a limited height so as to define a larger surface, wherein said stems are received in corresponding through-bores (not indicated in the Figure) provided in the foam material stuffing the support structure 8, and wherein said heads are arranged symmetrically relative to each other, so that the corresponding contour in the shape of a hemispheric cap 16 and 17 of the same heads faces the outer covering 12 and lies in contact therewith. In this manner, when nobody is lying upon the top surface of the support structure 8 and no load or pressure is therefore exerted thereupon, i.e. in the resting state represented in Figures 2 and 3 in which said surface remains perfectly horizontal, all such stem-head assemblies are not displaced and keep firm and motionless in their resting position.

When somebody on the contrary lies down upon the outer top surface of the support structure 8, and then moves into different postures thereupon, the various stems and related heads of the moving support members 9 displace vertically into varying positions by following the vertical displacement of the top and bottom outer surfaces of the same support structure, thereby continuously varying also the form of the top surface of the water mattress 6 lying therebelow.

Thanks to the particular conformation of the support structure 8, which is more rigid and compact and less elastic than the water mattress 6, the assembly formed by such support structure and the water mattress 6 allows for a much prompter, smoother and softer adjustment to the posture taken each time by the person lying upon the so provided support base, thereby effectively preventing such person from possibly running the risk of taking anatomically improper postures and developing deformations or alterations of the spinal column. Moreover, owing to the body of the person resting upon the support structure 8 - and not directly upon the water mattress 6, as this has been the case hitherto - the body itself, resting in this way upon a transpiring foam material, is allowed to more effectively transpire, while - on the other hand - being effectively prevented from running any risk of coming in contact with possible water leakages from the same water mattress, thereby keeping the hygienic and ergonomic properties of the so provided support base unaltered.

In Figure 4 there can be seen that the support structure 8 is provided with such elastic characteristics as to be able to be advantageously folded with a portion 18 thereof, as shown in dashed lines in said Figure.

Illustrated in Figure 5 there is the support base according to the present invention, in a second embodiment thereof. It can be noticed that the support structure 8 is even in this case resting upon an underlying water mattress 6, wherein this support structure is however configured in a different manner as compared with the afore-described one, since it is comprised of an outer covering 12 that is stuffed internally with a very flexible material 19, such as for instance latex or the like, in which there may be possibly embedded also suspension springs in a mutually independent manner (not shown). In the lower portion of such material there is further incorporated a material of the transpiring type 20, such as for instance preferably pierced-through plastic granules or spherules featuring a marked transpiring property such as to effectively allow for an adequate transpiration of the body of the person lying thereupon, wherein such further material is distributed over one or more superposed layers for a reduced overall thickness and over the whole length of the support structure being discussed.

A third embodiment of the support base shown in Figure 1 is illustrated in Figure 6, in which there can be noticed a support structure 21 that is again resting upon an underlying water mattress 6, wherein said support structure is in this case solely comprised of a single panel 22 having a limited thickness and the same length as the underlying water mattress 6, which is made of a rigid or semi-rigid material (such as for instance wood, stratified plastics, honeycomb pressboard, or the like, without any outer covering being provided in this case in deviation from the afore-considered embodiments, wherein also such panel is further provided with a plurality of moving support members 9 made in the same way as the afore-described ones and capable of displacing vertically in corresponding through-bores (not indicated in the Figure) extending throughout the thickness of the same panel. In this case, the stems 13 of the related moving support members 9 are made of plastics, or other suitable material, so as to be able to slidably displace along the corresponding through-bores in the panel 22, wherein this sliding displacement of the stems can be facilitated by keeping the through-bores appropriately lubricated or by possibly having bushings of some suitable self-lubricating and anti-friction material properly inserted in such bores for said stems to be able to slide therewithin. In this way, upon the upper heads 14 of the moving support members 9 there is laid an enhanced-flexibility mattress (not shown), on which a person is therefore able to lie down, and in this condition the individual stem-head assemblies are thus able to displace vertically to a varying extent depending on the weight of the person lying thereupon and the particular posture that is from time to time taken by the same person resting on the mattress placed thereupon. In the condition shown in Figure 6, in which nobody is resting on the mattress, all of the upper heads 14 are at the same time and in the same manner raised upwards, whereas all of the lower heads 15 are resting against the water mattress 6 lying therebelow and are urged with the planar bottoms 23 thereof against the lower side 24 of the panel 22.

The way in which a stem-heads assembly displaces is shown in Figure 7. In particular, Figure 7a shows the stem 13 in the condition in which it is displacing downwards in the direction A, so that the upper head 14 moves until it eventually reaches its limit, i.e. end-of-displacement position by positively abutting with its planar bottom 25 against the upper side 26 of the panel 22, whereas the lower head 15 moves downwards, thereby compressing against the underlying water mattress (not indicated in the Figure) and moving away from the opposite lower side 24 of the same panel. In the condition shown in Figure 7b there can on the contrary be noticed that the stem 13 is displacing in the direction B, which is exactly the opposite of the previously considered displacement direction, so that the heads 14 and 15 move into inverted positions.

Each head 14 and 15 can be produced by the overinjection technique, i.e. moulding it over a further corresponding fungiform head 27 and 28, which is smaller in size than the head being overinjected on it and firmly joined to the respective end portions of its own stem, wherein this smaller head may either be made integral, i.e. in a single-piece construction, with said stem or be in turn overinjected onto said stem. Furthermore, each head may be made and shaped in a variety of manners differing from the one described above by way of example, wherein it should anyway be provided with an adequately large surface in view of enabling it to establish an effective contact against the mattresses and, therefore, ensure an effective springy support to the person lying thereupon.

Illustrated in Figure 8 there is the inventive support base with all the moving support members 9 thereof displaced into different working positions, when a person is lying on the same support base, in the condition in which these moving support members rise and subside to different extents and in a different pattern in accordance with the posture taken by the person on the support base and the corresponding displacement of the surface layer of the underlying water mattress 6.

Figure 9 illustrates a moving support member 9 of the support base according to the present invention in a different embodiment thereof, in which there can be noticed that such member is even in this case comprised of an upper fungiform head 29 and a lower fungiform head 30, both of them being similar in construction to the afore-described heads of such members, wherein each such head is however joined, through a respective articulated joint 31 and 32, with a corresponding elongated rigid stem portion 33 and 34 that are rigidly connected to each other and both of them hinged by means of a pin 35 on the support structure 36 that is placed upon the water mattress and under the enhanced-flexibility mattress (neither of them being shown in the Figure, actually). Even in this case, therefore, both heads are capable of displacing vertically at the same time, i.e. concurrently, one upwards and the other downwards, depending on the postures taken and the movements made by the person lying on the mattress provided on top, and this way of displacing is allowed for by the rigid connection of the stem portions with each other and the articulated joint provided between each stem portion and the related head.

The same component part of the inventive support base as described above is illustrated in Figure 10, however in a different embodiment thereof. This component part of the support base is in this case provided in the form of a single panel 22 of a rigid material, exactly as the one described with reference to Figure 6, provided with moving support members 9 similar to the above-described ones, so that the related fungiform heads 14 and 15 of these moving support members are again protruding freely from both sides of the panel 22. As compared with the previously discussed embodiment, however, such component part is no longer provided in the form of a single-piece construction, but is rather formed as an assembly of a number of individual pieces linked with each other in the longitudinal direction and compliable into different positions, wherein each such piece is provided with said moving support members 9. In the example being discussed, such assembly is comprised of a middle piece 37 and two side pieces 38 and 39, differing in length from each other, of which the left-hand side piece 38 forms the foot-resting portion of the bed and the right-hand side piece 39 forms the head-resting portion of the bed. The side pieces 38 and 39 can be adjusted to a higher or lower position relative to both each other and the middle piece 37 by means of electric or other actuating mechanisms that are largely known as such in the art.

Figure 11 shows a person lying on a support base of the kind described with reference to Figure 6, however not using the top mattress, wherein the panel 22 is made of prevailingly rigid material. Shown in Figures 12 and 13 is a yet different embodiment of the support base according to the present invention, which in this case is comprised of a fluid mattress featuring a different conformation and made up substantially of a plurality of vertically displaceable moving support members 40 housed within an inner chamber 11 delimited by the outer covering 42 of the mattress and distributed all over the extension of the same mattress, wherein each such moving support member is comprised of the sole upper fungiform head 43 facing the outer covering 42 and in contact therewith, which is joined to the related short vertical stem 44 that in this case is slidably housed in an accommodation provided in a cylinder 45 therebelow, secured with its bottom against the outer covering 42. All inner chambers being defined by the various cylinders 45 are in fluid-tight communication with each other via related ducts 46 that are connected to an outer filler fitting 47 so as to be able to introduce a suitable fluid, i.e. the working liquid medium, into all such inner chambers, thereby enabling the stems 44 to slidably displace in this liquid medium with a pumping effect that causes the displacement movement of the same stems and the related fungiform heads 43 to be damped elastically. After working fluid has been filled in all of the inner chambers of the various cylinders 45, the inner chamber 41 of the mattress according to this embodiment of the present invention is evacuated, thereby making the same mattress ready for use. In this way, all heads 43 displace vertically along with the related stems 44 according to a different pattern, i.e. in a differentiated manner, when a person lies down upon the upper surface of the inventive fluid mattress being discussed, or even upon an enhanced-flexibility mattress laid thereupon, while the displacement movement of such heads and stems is damped elastically by the working fluid contained in the cylinders 45. By varying the amount of fluid introduced in the cylinders 45, the possibility is therefore given for the intensity of the elastic damping effect on the moving support members according to this embodiment thereof to be suitably varied. This elastic damping effect can be obtained also through the addition of possible springs in each such fluid-filled cylinder 45.

A fifth embodiment of the support base according to the present invention is illustrated in Figures 14 and 15, in which such support base is again comprised of a lower or bottom fluid mattress 48, which is made in the manner that shall be described in greater detail further on, and an overlying support structure 21 that is similar to the previously described one with reference to Figure 6 and, thus, comprises again a panel 22 with a plurality of moving support members 9, wherein an enhanced-flexibility mattress (not shown) may also be laid upon this support structure 21.

In this case, the fluid-filled mattress 48 is substantially comprised of a serpentine-like coiling structure 49, formed of a continuous tubular duct 50 bent in a manner as to form a sequence of rectilinear loops 51 extending over the full length of the mattress and arranged parallel to and slightly spaced from each other across the same mattress, wherein these loops are further formed so as to feature curved surfaces 52 in the bent zones thereof. One of the ends of this serpentine-like duct 49 is provided with the filler fitting 11, which is used to introduce water - or, as the case may be, any other appropriate working fluid - to completely fill the continuous inner chamber of the same entire serpentine-like duct. Even in this case, therefore, the moving support members 9 of the support structure 21 lying upon the fluid-filled mattress 48 come into contact with the upper surface of the latter while displacing vertically in different manners and to different extents depending on the weight of and the posture taken by the person lying upon the support structure 21, or the mattress possibly placed thereupon, so as to perform the same springing function as described hereinbefore.

A sixth embodiment of the support base according to the present invention is finally illustrated in Figures 16 and 17. As it can be readily noticed, the support base is in this case formed solely of a water mattress 53 of a traditional kind - capable of being internally filled with water or other suitable fluid, as the case may be, through the related filler fitting 11 - and along the peripheral edges of this mattress there are provided and secured corresponding rigid longitudinal panels 54 and 55, as well as corresponding rigid transverse panels 56 and 57, all of them made of some suitable material, so as to stiffen the structure of the mattress, which therefore becomes self-bearing, with the possibility for it to be inserted in any support structure of beds of a traditional kind, while preventing the same structure from displacing sidewise under the weight of the person that lies down on the upper surface of the same mattress. In addition, the entire structure of the mattress 53 is further stiffened by winding appropriate binding means, such as high-strength synthetic straps that are then fastened with their ends against the peripheral panels, round the mattress. In the illustrated example, longitudinal straps 58 and 59 can be noticed to be arranged to run parallel to and slightly spaced from each other, and to be fastened with their ends against the related transverse panels 56 and 57, while transverse straps 60, 61 and 62 can in turn be noticed to run parallel to and slightly spaced from each other, and to be fastened with their ends against the related longitudinal panels 54 and 55. These straps can be provided either externally to or internally in the support base.

The support base made and provided in the afore-described manner is therefore fully capable of effectively sustaining people lying thereupon, thanks to its relatively limited springing effect obtained with the above-described arrangements, without causing such people to undergo physical detriment, while also allowing for optimum transpiration, thereby maintaining hygienic and ergonomic characteristics at high-level qualitative standards.
