DESCRIPTION

Mattress structure for rest

The present invention relates to a novel resting mattress structure that efficiently exceeds what is known in the prior art.

BACKGROUND OF THE INVENTION

Traditional mattresses are made of flexible foam (tdi) with densities between 20kg to 35kg. They are foamed forming large blocks that are cut in the form of plates that are then superimposed to form the mattress structure. These mattresses have a short shelf life as they deform rapidly due to the low density and poor quality of the foams. In the mattresses thus made, the material used is a transmitter of heat and humidity and since there is no internal ventilation they accumulate damaging the structure of the mattress.

There are also a variety of mattresses that include springs in their structure, for example pocket springs, made of foam (tdi) and equipped with iron or steel springs inside. These mattresses generate pressure points in the support areas, deform and break rapidly, generating pressure points in the support and mobility areas during sleep.

In known structures the springs are associated with a metal cage or frame that limits the useful surface of the mattress.

ES 2496391 A1 describes a similar mattress with foam springs.

In view of the current state of the art in the art, a resting mattress structure essentially consisting of a box body formed by two halves molded in elastic material (foam), and an intermediate body also entirely proposed, is proposed based on the present invention. made of the elastic material obtained by molding, which consists of a plate that has two axially coincident opposite truncated conical projection assemblies that form a cushion assembly. The structure is complemented by a cover with closure that keeps the parts linked.

According to a feature of the invention, the frustoconical projections respectively have at their minor bases, a central perforation or recess and grooves perpendicular to said perforation, thereby increasing the damping action of said projections.

According to another advantageous feature, the side walls of the halves that form the case body have perforations for internal mattress ventilation.

The constructive solution provides the following comparative advantages:

• The mattress can be used on the entire surface because its structure has no elements

metal.

• The cavities of the molded halves that form the body of the box form pneumatic chambers in which the foam projections that form the cushions are housed, thereby preventing the accumulation of heat and moisture in the mattress structure.

• The position of the projections (cushions) make the mattress have good stability preventing the movements of a person from being transferred to the adjacent areas of the mattress.

• The structure does not deform which avoids the need for mattress rotation.

• The mattress obtained is completely removable and washable as is the cover.

Other features and advantages of the object of the invention will be explained in the description that follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The mattress structure object of this invention essentially comprises a molded case body of elastic material, formed by two overlapping halves (10) (10 ') faced by their respective open faces, a molded intermediate body of elastic material (20) constituting a shock absorber assembly, and a peripheral peripheral support means (30) of said halves (10) (10 ') and intermediate body (20).

The structure in question can be made for all sizes according to conventional mattresses, a square, a square and a half, two seats, etc., also the box body can have any typical format, for example, square, rectangular, circular, etc.

The molded parts of elastic material (10), (10 ') and (20) are made by injection molding technique. The material used is preferably cold-molded flexible molded foam, of the type obtained by a mixture of Polyol and Isocyanate, for example, of known type and diffused with the Elastoflex XBF-017CMC and Elastoflex XBT-024 brands, where the first component is a mixture of polyols, containing catalysts, stabilizers and expanding agent and where the second component is Methylene Diphenyldiisocyanate (modified MDI).

It should be noted that the indicated parts that make up the present mattress can be made of other elastic materials with different densities.

The halves (10) and (10 ') are molded bodies constituted by respective contour walls (11) (11') and respective closing walls (12) (12 '), delimiting paths that form pneumatic chambers (c) ( c '), which are connected to the atmosphere through perforations (13) (13') of the contour walls (11) (11 ').

The intermediate body (20) comprises a wall (21) of uniform thickness that perimetrically supports between the facing edges of the respective contour walls (11) (11 ') of the two halves (10) (10') of the case body , constituting the support of the mattress cushion assembly. This wall (21) has on its major faces respectively a plurality of truncated conical projections (22) (22 ') distributed forming matching regular orthogonal frames. The projections (22) (22 ') are contained in the respective pneumatic chambers (c) (c') having a similar height as said cavities.

To improve the damping function of the frustoconical projections (22) (22 '), they are provided in the smaller bases of respective blind axial perforations (23) (23') and respective grooves (24) (24 ') perpendicular to said perforations

Preferably, some of the grooves (24) (24 ') are aligned with one of the perforations (13) (13') of the contour walls (11) (11 ').

With the inventive solution of the present mattress, when applying a force on the surface of the wall (12), said force

it is promptly concentrated by axially compressing the immediate projections (22) (22 ') and the air can flow freely through the perforations (13) (13'), while, upon removing said pressure, the elastic memory of the material causes the shock absorbers to return to the initial format, the chambers (c) (c ') being filled again through the mentioned perforations (13) (13').

5 The peripheral support (30) is a laminar sheath made of fabric shaped according to the geometry of the case body.

More in detail and according to the illustrated example, the sheath (30) comprises an upper wall (31), a lower wall (32) and a contour skirt (33) sewn perimeter. The skirt (33) has an opening with zip closure (34) and windows (35) coinciding with the perforations (13) (13 ') of the contour walls of both halves that form the case body.
