Definitions
- the present invention relates to a number of improvements which can be made in any conventional mattress, tending to allow the firmness or deformative strength of its operative surface as against the user's bodily weight to be adjusted at will by means which enable such degree of firmness to be easily varied.
- Bed structures have changed considerably in time, to such an extent that as opposed to old-fashioned extremely soft beds which adapted perfectly to bodily contours, a certain type of current beds has now been arrived at in which the bed materialises as a rigid duly upholstered board on which an elastic element comprising the mattress is arranged which offers a maximum firmness or hardness, a complementary moulding being therefore established between the user's body and the mattress, moulding of the user's body being greatest, to suitably profile his or her back.
- the invention lies in replacing said conventional layers of padding with a reticulated body in which a plurality of transversely elongate and longitudinally adjacent screens or pneumatic chambers are defined, each having its own inflating system, the user being therefore able to provide a particular pressure at will for each such transverse chamber, the firmness of the bed therefore varying along the same, depending upon the extent of pressure existing in each of its areas.
- the bed has been designed to be provided, at any suitable location thereof, with a small compressor fitted with a standby air tank from which the desired pressure can be supplied to any of the chambers making up the bed, through suitable valves, each chamber being fitted with a release valve, distinct from the filling valve, which allows pressure therein to be lowered when this is deemed fit.
- the filling valves will preferably materialise as electrovalves which, as aforesaid, will be independently driven by the user.
- transverse chambers have also been provided to be split into two, by means of a longitudinal midwall, and thus two laterally adjacent areas of equal size are established in such bed for both users, also independently adjustable insofar as hardness is concerned, by means of a similarly independent inflating system.
- the bed has also been finally provided to optionally be fitted at its longitudinal edges, or optionally along its entire perimeter, with another inflatable cushion which can be given a substantially greater firmness than the transverse chambers, thereby for said side cushions or as appropriate the perimetric cushion to determine a retaining means, resembling a railing, ensuring that the user is retained within the bed.
- Said reticulated body can constitute a physically independent element of the central elastic core of the mattress, which core can in turn even made with springs, polyurethane foam, latex or even water, which reticulated body may otherwise be integrated with the central elastic core of the cushion, forming a single unit containing both their properties and qualities.
- the pneumatic chambers making up the reticulated body can be included within the springs as such.
- Figure 1.- Is a schematic, partial, side elevation and sectional representation of a traditional mattress to which the improvements of the invention apply.
- Figure 2.- Is a schematic plan representation of the reticulated body applicable to the mattress of the preceding figure, replacing its pad, made in accordance with the improvements of the invention.
- Figure 3.- Is an enlarged partial and perspective close-view of the reticulated body of the preceding figure.
- Figure 4.- Is a schematic perspective view of a reticulated body designed for a double bed, which also shows a schematic representation of the compressing equipment and standby air tank.
- Figure 5.- I is a schematic perspective view similar to that of figure 4 of a different embodiment of the reticulated body in which the body is also fitted with a pair of very firm side longitudinal cushions, acting as "railings".
- Figure 6.- Is a profile close-view of the body of figure 5, wherein the effect of the side cushions may be observed.
- Figure 1 shows, as aforesaid, a traditional mattress structured on the basis of a central elastic core (A), which may comprise springs, polyurethane foam, latex, etc., lined on either side with a pad (B), respective layers (C) of quilting or cushioning lying outside such pads (B).
- A central elastic core
- B pad
- C respective layers
- the improvements of the invention lie in replacing at least one of the pads (B) with a reticulated body (1) having a basic flattened prismatic-rectangular configuration resembling that of a conventional mattress, in which there is a bottom laminar wall (2), a top laminar wall (3), a side perimetric wall (4), which complements the prismatic body, and a number of inner transverse and vertical dividers (5) defining a plurality of transversely elongate screens or chambers (6) which may affect the whole width of the bed, as in the practical embodiment shown in figure 2, or which may be split into two with the assistance of a longitudinal midwall (7), as in the embodiment of figures 4 and 5.
- the said deformable chambers (6) are in any event designed to be pneumatically inflated with the assistance of a compressing equipment (8) lying, for instance, next to the head or foot of the bed, and assisted by a standby air tank (9), which compressing equipment need therefore only be switched on when the tank (9) is empty, the equipment supplying pressurised air to the chambers (6) through respective electrovalves (10) assisting each chamber, and therefore upon actuating such electrovalves (10) one by one, the user may provide each chamber (6) with a particular pressure, equal to or distinct from the pressure of the remaining chambers in the body, and may consequently establish different degrees of firmness throughout the same, to achieve maximum bodily comfort, which adjustment is, in the case of double beds, as shown in figure 4, independent for each of the two users of the bed, since both the chambers lying on the right-hand side of the body and those lying on the left-hand side are provided with respective individual electrovalves (10).
- the transverse chambers (6) of the body have additionally been provided to optionally be laterally and longitudinally framed by two pneumatic cushions (11), in turn fitted with respective inflating electrovalves, which cushions may optionally also affect the edges of the body at the head and foot of the bed and which are in any event designed to receive an inflating pressure substantially in excess of that of the transverse chambers (6), and therefore, as shown especially in figure 5, said pneumatic cushions (11) are raised in respect of the remaining body, acting, since they offer a considerably greater firmness than the latter, as railings or containing walls holding the users duly stabilised as they lie on the bed, eliminating the risk of falling.
- the reticulated body (1) can be independent of the central elastic core (A) of the cushion or make up a single unit with the latter including both their properties and qualities.
- the central elastic core (A) is constituted by an innerspring
- the pneumatic chambers constituting the reticulated body (1) may be included within the actual springs.
