- a furniture element is proposed according to the invention, characterized in that it comprises a first flexible inner envelope defining, within it, a first volume capable of receiving a material comprising a fluid with a first density and a second flexible envelope, outer, the inner envelope and the outer envelope together defining a second volume surrounding the first volume and containing a second material comprising a fluid and flexible particles with a second density greater than the first density, a first orifice closable to the fluid inlet or outlet for the first volume, opening on the outside, and a second closable orifice for the fluid inlet or outlet for the second volume, opening on the outside.
- the two envelopes are made of a flexible synthetic material weldable, the two envelopes being locally welded to each other.
- the inner envelope is formed of panels assembled to give it a general shape when pressure prevails in the first volume.
- the outer casing is formed of panels assembled to give it a general shape similar to that of the outer casing.
- the first orifice is located in one of two envelopes attachment region to each other, to simultaneously pass through the two envelopes.
- the first material comprises a compression coefficient material / high expansion so as to provide a character in the first volume at least partially self-inflating when the first port is open.
- the second material comprises a mixture of gas and particles.
- the particles comprise a mixture of foam and fiber chips.
- the average particle size is between 5 and 30 mm.
- a gate is associated with the second port to prevent the escape of the particles when said orifice is open.
- the element further comprises a third port between the second volume and the outside, permitting the injection of the mixture of gas and particles therethrough and the discharge of excess gas through the second orifice.
- a non-return valve is associated with the third orifice.
- the element further comprises a third casing, cladding, surrounding the second envelope removably.
- FIG. 1 is a view in longitudinal section of an example of a seat according to the invention
- FIG. 2 is a perspective view of the seat of FIG. 1, and
- Figures 3 and 4 are perspective views from the rear of two details of a seat according to the invention, Figure 3 being a representation of an inner casing, and Figure 4 that of an outer casing. Detailed description of an embodiment
- FIG. 1 there is shown a furniture element in the form of a chair-type seat with a seat A and a folder D.
- An outer shell 10 defines the general shape of the seat, with a ground support area 101, a frontal area 102, a seating area 103, a backrest area 104, a backrest area 106, a seating area 105 and two side zones, one 107 being shown in the section of Figure 1.
- the outer lining material 10 is a soft membrane preferably weldable and airtight, in particular PVC.
- an inner casing 30 made of an airtight and weldable material such as a PVC membrane.
- This envelope 30 separates the space 20 defined globally by the inner envelope 10 into a first interior volume 22 delimited by said envelope 30, and a second external volume 21 surrounding substantially the entire interior volume 22.
- the inner envelope 30 is connected to the outer envelope 10 in a limited number of regions, and in the present example here in two regions, namely a region R1 located in the front portion 103 and a region R2 located in the portion of
- connection regions are provided depending on the shape sought for the element, so as to leave a significant freedom in the shape of the outer envelope 10 with respect to the shape of the element. the inner envelope 30, as will be seen later.
- two link regions in opposite parts of the element will be provided.
- the connection between the two shells is preferably performed by welding the membranes to secure them to a surface of the order of 50 to 500 cm 2.
- the shape of the inner envelope 30 inflated is obtained by welding together a set of panels of particular shapes (in this case two panels, a panel and a top bottom and back panel), and by providing, where appropriate, the panels, in particular the top panel and the bottom and rear panel, of stiffening lines (material thicknesses), in a manner known per se in the field of mattresses and other recreational pneumatic articles.
- the outer casing 10 can be made by welding together a number of panels, with a general shape similar to that of the inner casing, and a larger size (typically 20 to 50% larger).
- the inner volume 22 communicates with the outside by a sealed cap, for example of the type of inflation nozzle used in the aforementioned field of pneumatic articles, the plug 40 being preferably located within one of the regions R1 and R2 so as to simultaneously cross the material thickness of the outer casing 10 and the material thickness of the inner casing 30.
- This cap allows to apply an air pressure or another gas, adjustable within the interior volume 22, and virtually empty this interior volume.
- the stopper 40 advantageously comprises a non-return valve, in a manner known per se.
- the external volume 21 communicates with the outside by at least one plug, preferably a leakproof screw plug 50 of section typically between 10 and 30 cm 2 , provided with a gate 51 whose size openings is sized to avoid the particle release, for purposes explained below.
- This cap is preferably located in the back area 105 of the seat so as not to hinder comfort.
- the external volume 21 is filled with a material of filling, either through the opening of the stopper 50, or before closing the casing 10 (for example by sewing).
- the filler material is a particulate material
- the particles comprise a mixture (preferably about 50/50) of foam chips for example of polyester and fibers such as polyester.
- the average size of the particles is preferably between 5 and 30 mm.
- Such a mixture makes it possible at the same time to guarantee an excellent comfort and to ensure that the mobility of the particles in the second volume is neither too important (an area likely to be entirely devoid of particles), nor too weak (the characteristic of shape variability, depending in particular on the posture of the subject, being important especially in the case of large cushions or terrace or pool seats).
- the filling is preferably performed by injection into a stream of air or other gas.
- the material of the outer casing 10 is for example a woven or non-woven material easily passing air, but whose openings are much smaller on the size of the particles of the filling material.
- the outer casing 10 can be provided with two plugs, with a plug 45 for filling during manufacture, having a clear and sufficiently large passage (typically around 10 to 30 cm). cm 2 ) for injecting the particles into an air flow, and the other 50 possibly with a passage of smaller section, having a grid 51 as mentioned above with openings allowing the exit of the injected air while preventing the exit introduced particles.
- the plugs 45 and 50 are preferably screw plugs, and the plug 45 is provided with a non-return valve avoiding any risk of exit of the filling material when the plug is unscrewed. Then, the plug 50 or plugs 45 and 50 being closed (s), the internal volume 22 is filled with air, using a filling tip (not shown) sealingly connected to the plug 40 This can be done either with the mouth or with a manual or motorized inflator.
- the inflation pressure determines rigidity and "softness", and can be adjusted to any desired value without exceeding a certain limit.
- the set is preferably placed in a cover or casing made of selected material and color (typically a thick canvas of polyamide or polyester, leather, etc.). and the seat is ready to use.
- a cover or casing made of selected material and color (typically a thick canvas of polyamide or polyester, leather, etc.).
- the internal volume 22 of its air is emptied, either by pressing on the seat after opening the cap 40, or by connecting a vacuum pump, then closing preferably the plug to prevent a new air intake.
- This allows a decrease in seat volume corresponding substantially to the internal volume 22.
- a volume reduction of 25 to 50% typically about 35%.
- the filling material is a particulate material
- the grid provided in the plug 50 makes it possible to apply a vacuum pump without the risk of removing filler material.
- air is re-injected into the interior volume 22 and, where appropriate, into the exterior volume, and the furniture element can be used after putting on or replacing the cover.
- the fact that the outer envelope 10 and the inner envelope 30 are connected to each other at a limited number of bonding regions makes it possible to retain considerable freedom of shape, the material located in the external volume 21 can move (more or less spontaneously depending on the nature of the material) depending on the various constraints (gravity, pressure exerted by the user).
- the element may comprise several interior volumes and / or several external volumes, particularly depending on considerations of form, comfort and strength; in this case, the interior volumes may or may not communicate together, so as to equalize or not their pressures;
- the filler material may be of different types: microbeads, synthetic fibers, foams, gels, of suitable materials such as polyester, expanded polystyrene, etc. or any mixture of these elements.
- suitable materials such as polyester, expanded polystyrene, etc. or any mixture of these elements.
- Different filling materials, and / or different filling densities, can also be provided in different volumes or compartments depending on the part of the furniture element under consideration (seat cushion, seat back, etc.);
- the material filling the internal volume 22 may be either a fluid, typically air or, more generally, a gas, or even a liquid such as water, or a material with a high compression / expansion coefficient so as to give the first volume at least partially self-inflating character when the stopper 40 is open;
- the element may comprise different parts assembled to one another (by seam, zipper, snaps, Velcro®, etc.) permanently or dismountably;
- Partitions may be provided connecting in some places, in the thickness of the peripheral volume, the outer casing 10 and the inner casing 30, so that the internal volume 22 is placed in the desired position in the seat;
- this connection may optionally be separable (Velcro®, etc.).
- the invention is particularly applicable to elements of the type seats or cushions of large volume (typically 0.2 to 1 m 2 ) for outdoor (terraces, swimming pools).
