Description

Filler buffer device for mattress and upholstery.

Object of the invention

The present invention relates to a padding cushion for upholstery and upholstery, intended to establish the fluffy interior of mattresses, cushions, Pillows and the like.

Background of the invention

Currently, mattresses are designed to be fluffy and act as shock absorbers under the weight of the person or persons, using among other materials thick blocks of foam rubber.

Also a lot of furniture, such as armchairs, sofas and other elements, use for the seat foam rubber shock absorbers under the upholstery, which They make them more comfortable when people sit or lie down. So much the mattresses as cushions present these elements of damping constituted by the elastic padding within minus an outer cover and / or upholstery that is decorative, in textile material, leather, or others.

Generally, these fillers used in mattress and upholstery are made up of blocks of foam rubber alone or by a layer of substantially thick foam rubber and which in their upper and lower faces have at least one layer additional reinforcement that can serve to mold resistance and weight behavior when a person lies down, feels, or rest on

However, there is a problem that, with the use, foam rubber loses its resilience, forming depressions, so that the outer appearance is damaged when forming cradles or holes corresponding to the areas that have suffered compressions, but they have not recovered to their original position.

Description of the invention

The filler buffer device for mattress and upholstery, object of this invention presents some technical peculiarities aimed at improving the aesthetic appearance of mattresses and other elements upholstered by maintenance of the correct expansion of the foam rubber used

This device comprises a layer of foam rubber in which a plurality of substantially vertical holes in which they are located housed respective biconic springs, divergent towards the ends and oriented perpendicular to additional layers upper and lower.

These springs have a nominal length greater than the thickness of the foam layer and, in the position of assembly feature a certain precompression, pushing the layers upper and lower, which are attached so Conventional to the foam rubber layer.

During use the device shock absorber, springs and foam rubber layer deform elastically, providing cushioning, but upon cessation said compression, the springs expand acting against the layers upper and lower and make the foam recover completely its original position and extension, getting the exterior or upholstered cover, present a tense and optimal appearance. To the be the biconic springs divergently towards the ends, they have a larger contact surface at their ends diameter than the diameter in its middle part, which ensures that when pressed, they do not jump and the effort is distributed wider way.

The biconic springs and the through holes are distributed to the triplet in the layer of foam. In this way a better distribution of the combined forces during compression and recovery of damping device

Each spring has an outer textile cover of protection or bagging, such as a bag of waxed tissue, which protects the metallic material from moisture and perspiration with which the spring is constituted, preventing its oxidation and lengthening its useful life.

It is also planned in an alternative of realization that the spring can incorporate inside a block of foam rubber, for example the taco itself produced at make the hole in which the spring is housed. This taco increases the spring rigidity and therefore improves resistance to compression, thus admitting more weight with less deformation.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows an elevation view of a portion of the damping device vertically sectioned.

- Figure 2 shows a plan view of the foam rubber layer showing the distribution of the holes interns, especially for a mattress.

- Figure 3 shows an elevation view sectioning of a detail of the biconic spring within a protective textile cover.

- Figure 4 shows an elevation view sectioning of a detail of the device with a foam rubber block in a biconic dock.

- Figure 5 shows in several steps the Device configuration and nominal length difference of the spring with respect to the hole in which it is housed for precompression.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the padding damping device, in this case for a mattress, it consists of a layer of foam rubber (1) of sensitive thickness having a plurality of holes (11) interns between its upper face and its lower face, distributed of regular way to tresbolillo, being housed in said holes (11) a plurality of biconic, divergent springs (2) towards the ends, of metallic material and precompressed.

On the upper and lower faces of the layer of foam rubber (1) there are two additional layers (3) of reinforcement, constituted in this case by some burlap sheets resistant against which the ends of the springs act (2), and two layers of foam rubber coating. In this case the damping device may comprise an outer sheath (6) padded and optionally an upholstery (7) or bed sheet coating, among other finishes that you want to apply.

In the exemplary embodiment shown in the Figure 3, the spring (2) is packed in a textile cover (4) protective outer, for example a waxed fabric for the protection of said spring (2).

As seen in figure 4, the spring (2) bicónico can present in his breast a block of foam rubber (5) of reinforcement and stiffening, arranged axially, and in this case obtained from the drilling of the hole (11) in which the spring (2).

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
