Abstract

Seat furniture. It is a seat furniture that comprises in principle a structural compartmentalized cover that, in a particular case of sofa, includes different corresponding cavities with the backrest, seat, armrests and other parts of the sofa, so that in these cavities They will adjust and fit bags filled with a consistent material, so that these bags are the elements that really assemble the sofa set, thus obtaining a product of low cost and easy to transport due to its small volume as a result of being able to transport it disassembled unlike of conventional sofas that need to be transported fully armed. The bags can comprise a single compartment or several, in the latter case each compartment can be filled in turn with different materials to obtain different hardnesses.

Description

Seat furniture.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a piece of furniture seat that presents the particularity of not incorporating any type rigid internal structure as a support for the seat furniture, but without losing comfort and consistency necessary.

It also has the same functionality and features that a conventional seat furniture with its rigid support structure, but with the added advantage of being a  seat furniture with reduced weight, low cost and more ecological than conventional ones.

It should also be noted that its transport results simpler and cheaper due to its reduction in volume and weight at be able to transport it disassembled.

Background of the invention

There are currently different sofas and others  seating furniture, most of which incorporate a rigid internal structure on which they are then fixed differently fluffy parts and bodies to get the best comfort possible.

These seats are heavy and production complex.

There are other sofas and armchairs that lack internal structure.

For example, Utility Model No. 154,644 is refers to an inflatable chair that is characterized because it comprises a solidarity set consisting of several hollow bodies that They fill with pressurized air.

The Invention Patent with number of publication US6234577 consists of an armchair comprising a flexible enclosure with a first compartment and a second compartment; and a fill area arranged inside both compartments It also includes a dividing part arranged inside the enclosure that separates both compartments.

It is characterized because the enclosure differentiates a top, bottom and a dividing line between the two, where the dividing part includes a first and second end, in the that the first end of the dividing part is fixed to a point of the upper part of the inner enclosure, and where the second end of the dividing part is fixed to an interior point of the part lower enclosure.

It is also characterized because the bottom extends from the top to define both the part front as the back of the chair, where the first end of the dividing part is fixed to the front part, and where the second end of the dividing part is fixed to the back of the lower part, place where the dividing part is not elastic.

The Invention Patent with number of Publication 3899210 refers to a "puff" consisting in:

-

armchair-cushion assembly consisting of a completely enclosed cover with volume unitary interior in which each of the parties communicates freely with the adjacent one, and with a plurality of granules resistant movable inside and partially filled said cover made of expandable polystyrene foam;

-

support structure consisting of a circular edge attached to at least one member base arranged below, which defines an interior space whose dimensions are much smaller than the corresponding ones of said puff and that serves as support for the armchair-cushion and substantially limits the internal expansion of the same, therefore, the aforementioned armchair-cushion rises above ground level normal of a chair, and its granules generally move in upward direction inside the aforementioned chair when the mentioned cover is under the weight of a seated person over.

Invention Patent WO 00/35318 refers to a piece of furniture consisting of a cover made of flexible and air-impermeable material, with a top, lower and intermediate, which connects with the mentioned parts lower and upper, with a material that fills the aforementioned cover and a means both to limit changes in the way when a person takes a seat to compensate for the reduction of the volume resulting from crushing and / or material wear of filling mentioned above.

Invention Patent GB 2059758 refers to a puff consisting of a cover made of a flexible material substantially inextensible modeled so that when filled with material composed of polyurethane foam granules, it turns a piece of furniture with a rear area and base that also incorporates a rear panel and an attached seat panel for the user support the back and buttocks respectively, with a panel bottom under the seat panel and a rear panel behind of the rear panel, plus two side panels; with an opening of sealable filler through which the granules and a substantially inextensible elastic cord that is extends inside the cover from an adjacent position or right at the junction point of the back panel and the seat panel of the bottom panel.

Description of the invention

The seat furniture that constitutes the object of the invention is characterized in principle because it comprises some bags filled with a fluffy material with greater or lesser hardness, with higher or lower density, for example perlite or granulated type, although It could be any other suitable product. Usually they will use grains of material as light as possible easily filled by pneumatic drag methods such as polymers, polypropylene, polystyrene, polyethylene, etc.

Each of these bags with the filling of material constitutes a part of the seat furniture, so that on a sofa we will have for example a bag for each armrest, another for the backrest, another for the seat, etc, with the same or different density

These bag volumes are housed inside of compartmentalized spaces established in a cover flexible structural with at least one access mouth, so that a compartmentalized space of the cover is separated from the adjacent compartmentalized space through an intermediate partition It is part of the case.

Normally each compartmentalized space will have an access mouth to adjust inside the bags, although there is also the possibility that several compartmentalized spaces have a common mouthpiece corresponding to the space larger subdivision.

Another important feature of the invention is that each of the bags comprises a substructure formed by intermediate partitions that separate different compartments, and confer rigidity to the volume of the bag, partitions that incorporate communication passages between the adjacent compartments so that the filling of these compartments generated be faster and above all more correct, thus avoiding any possibility of gaps and spaces
empty

In another embodiment, the possibility of that the compartments of the bags are independent and able so fill them with different materials and therefore with different densities, resulting in different hardnesses adapted to the ergonomics of the seat furniture and ultimately a Greater comfort for the user. In this embodiment the most normal is that each compartment has its own access point, although it would also be possible to incorporate a single common mouth as long as one of the ends of the compartments flow into that common mouth.

In another embodiment of the structure of the bags with special shapes and / or lacking the necessary rigidity, the possibility of incorporating rigid structures is planned independent that will obviously be introduced by mouths of access to the bags to place them in the volume they occupy the filling material, with interposition of a laminar element that can be part of the bag, getting with it advantageously increase the consistency, strength and rigidity of the bags and therefore the seat furniture in the areas that are  They incorporate these bags.

Another feature of the invention is that bags have reinforcements on their edges coinciding with the edges or edges of the sofa, so that this feature along with the incorporation of intermediate partitions provide greater stiffness and solidity of the seat furniture to prevent it from not sinks when the user sits. Reinforcements can also incorporated into the corners of the bags.

So, once all the forms have been filled in  bags, these are introduced into the case, essentially of material foam, which gives them the final look of a traditional armchair. Finally, the outer fabric or cover is placed on top of this cover that will give you the desired look, be it a leather case, or some determined tissue

The advantages of the new seat furniture invention, among others, are the following:

-

Minor cost due to the material used.

-

Minor weight of the seat furniture.

-

Best manageability

-

Improvement in the transport.

-

Ecological on-site manufacturing methods.

-

Possibility of using different densities of the filling material, according to the area a Fill.

-

Easy storage of furniture unfilled seat.

-

Easy to fill the furniture of Seat in the store itself.

-

Facilitate the design of furniture seat when using only flexible materials (fabrics, canvas, foam, etc.) that do not condition their shape as they do conventional rigid structures.

Normally the bags will be made of textile materials and even those mentioned above, although It is also possible to manufacture the bags with a material heat sealable, joining its different parts by heat sealing, as well as the access mouths. Even when this material heat sealable, in addition to being waterproof, will be incorporated microperforations to facilitate the exit of air during the filling the bags and thus avoiding gaps and defects in the Obtaining the resulting bags.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the seat furniture comprises, in principle, at least one flexible cover of compartmentalized foam 1 where several open cavities 2 are defined in which respective bags 3 are fitted with a filling material 4, perlite type or other granulated materials, so that once these bags 3 have been introduced and adjusted inside the cavities 4, they are closed, thus forming and assembling the assembly of the seat furniture in principle. Said cavities 2 are separated from each other by intermediate partitions 5 that are part of the
case 1.

The edges of the bags, and even the corners incorporate reinforcements 6 and 7 to help better shape the seat furniture assembly.

In turn, the cover 1 can also incorporate reinforcements 8 and 9 in the edges and especially in the corners

Each of the bags 3 constitutes a part of the seat furniture, so that in the particular case of a sofa, we will have a bag 3 for each armrest, one for the backrest, another for the seat, etc.

The sofa will be covered with an outer cover decorative 15 that can be of any material.

On the other hand, the bags can incorporate a single compartment occupied by a filler material, such as it is shown for example in figure 3, although the bags can present other configurations and structures such as represented in figures 5 to 8.

Thus, the bag 3 can incorporate a internal substructure formed by internal partitions 10 that separate different compartments 12, partitions that incorporate steps of communication 11 between the compartments so that the filling of these compartments generated be faster and especially more correct, thus avoiding any possibility of gaps and spaces  gaps, and also variations in the density of a busy volume by the same filling material 4.

In another embodiment, the possibility of that the compartments 12 'of the bags 3 are independent and so fill them with different materials and therefore with different densities, resulting in different hardnesses adapted to the ergonomics of the seat furniture and ultimately a Greater comfort for the user. In this embodiment the most normal is that each compartment 12 has its own access mouth 13, although it would also be possible to incorporate a single mouth common as long as one of the ends of the compartments 12 flow into that common mouth 13.

In another embodiment of the structure of the 3 bags with special shapes and / or lacking the necessary rigidity, the possibility of incorporating structures is planned internal rigid 14 that will obviously be introduced through the mouths 13 of the bags 3 to place them in the volume that occupies the filler material 4, with the possibility of interposing an element laminar 16 attached to the envelope material of the bag 3, being able to said element being part of the bag 3, thereby achieving advantageously increase the consistency, strength and rigidity of the bags 3 and therefore of the seat furniture in the areas that these bags are incorporated 3.

Optionally the cavities 2 of the cover Flexible structural 1 can accommodate blocks or pieces 17 of elastomeric material or similar instead of the mentioned bags 3 in order to achieve different effects on the seat in what relative to hardness, comfort, etc.
