Abstract

Improvements introduced in the invention patent P200302161 for "mattress with inserts of variable elasticity". It incorporates a block (1) of foam, preferably molded, which receives tubular inserts (2) in which solid cores (3) of variable elasticity are inserted in correspondence with different support areas of the user's body, as well as incorporating a upper layer (4) of foam, preferably viscoelastic, on which the user's body rests, which is elastically deformed by weight in different sectors and to a different degree depending on the tubular inserts (2) and solid cores (3) introduced and regains its flat position when the user withdraws. The solid core (3) is of oval section determining different positions inside the tubular inserts (2) defining, according to orientation, a clearance (6) between the core (3) and the inner wall of the tubular insert (2) which determines a variable degree of firmness, customizable by the user.

Description

Improvements introduced in the invention patent P200302161 by: "Mattress with elastic inserts variable".

Object of the invention

The present invention relates to a series of improvements proposed in the P200302161 Invention Patent which is refers to a mattress of the type that incorporates elements exchangeable elasticity in different sectors of the mattress.

It is the object of the invention that the mattress incorporate a viscoelastic upper base that shows a shape permanently flat except when deformed, adapting to user body shapes depending on the incorporation of inserts of different degrees of elasticity located in different sectors depending on the profile and weight of the user.

The object of the invention is also the incorporation of solid oval geometry cores that introduced into the tubular inserts inside the which can be rotated by determining a variable clearance that defines also a variable degree of firmness.

Background of the invention

In the invention patent P200302161 describes a mattress that incorporates empty tubular inserts integrated into a molded block that forms the base of the mattress in which nuclei are introduced or extracted with great simplicity solid polyethylene or other deformable elastic material variable or rigid.

The mattress comprises a top layer preferably of viscoelastic material and a molded block in the  that tubular inserts are distributed transversely cylindrical of expanded polyethylene or other deformable material that may or may not incorporate the solid cores that are introduced laterally in said tubular inserts in different sectors user support according to the comfort criteria of East.

The molded block consists of a single piece which is obtained from foaming with the inserts tubular previously located inside in the vicinity of Your upper face. The greater or lesser elasticity of the different mattress sectors will be determined by the introduction or subsequent modification by the user of solid cores of different degree of elasticity in these sectors.

The tubular inserts can be extended by the entire width of the mattress or in the case of mattresses marriage, the insertions could only last until the half of the mattress, with a distribution in number and position in each of said halves depending on the complexion and weight of the person who regularly occupies that sector of the mattress.

The possibility of using the same core solid to achieve different degrees of elasticity according to your guidance, as well as optimization in the use of materials to facilitate the elastic deformability of the top layer on which rests the user make the invention feasible that described in this certificate of addition.

Description of the invention

The present invention proposes a mattress incorporating a foam block, preferably molded, such as molded AirVex ®, in which tubular inserts are inserted in a plane close to its upper face and on which an upper layer is located of deformable viscoelastic material due to the effect of the weight of the body in varying degrees according to the distribution of tubular inserts and the possible incorporation or not of solid nuclei inside. The body resting on the mattress will feel the greatest firmness in correspondence with those sectors of the mattress that house the tubular inserts with the possible cores inserted there.

The incorporation of only the top layer in viscoelastic material, on the molded foam base block allows an optimal transmission of body weight until inserts and therefore a deformation of said upper layer adaptable to the user's shapes, recovering the surface flat when the user stops leaning.

In the invention patent P200302161 contemplates the modification of the degree of firmness based on the introduction or not of solid cores with different elasticity. In This invention proposes the possibility that the same core massif can transmit different firmness depending on its position inside the tubular insert.

For this reason the nuclei adopt a oval configuration, so that its vertical positioning in the inside of the tubular insert determines a greater firmness than if the core meets its major axis in disposition horizontal. In this horizontal position there is a free space between the core and the inner wall of the tubular insert that facilitates the deformability of the tubular insertion by determining a less firmness than that obtained when that space does not exist at be covered by the solid core when it is oriented vertically

The possibility that the mattress lacks tubular inserts and that solid cores oval are introduced directly into cylindrical holes provided in the block that would normally receive the insertions tubular

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a sectioned side view of the mattress on which the user's body is supported on it and in which the deformation of its layer is appreciated superior and the different orientation of the solid cores that determines a variable deformation of the different sectors of support, as well as an enlarged detail of a core introduced in a tubular insert.

Figure 2.- Shows a sectioned side view of the mattress without user in which the recovery of the flatness of the upper layer.

Preferred Embodiment of the Invention

The mattress with inserts of variable elasticity which constitutes the object of this invention part of the incorporation  basic of a block (1) that integrates cylindrical holes (5) transverse, which receive tubular inserts (2) of variable elasticity in which solid cores are inserted (3), or they receive directly to the solid cores (3), which are variable elasticity easily insertable and removable in correspondence with different support areas of the user's body that require a varying degree of deformability, as well as incorporates an upper layer (4) on which the body of the Username.

From this basic constitution the mattress It stands out mainly because the block (1) is obtained in foam, preferably molded, and the top layer (4) is foam, preferably viscoelastic, which is elastically deformed by the user weight in different sectors and in different degrees in function of tubular inserts (2) and solid cores (3) introduced

As shown in figure 2 the material viscoelastic facilitates the upper layer (4) to recover again its flat position when the user withdraws.

It is also noteworthy that the solid core (3) It is oval in section and determines a clearance (6) between the core massif (3) and the inner wall of the tubular insert (2) in its Oriented positioning inside the tubular insert (2) which determines, according to the orientation of the solid core (3), a variable degree of firmness.
