Definitions
- the present invention relates to new cells inflatable, called telescopic, cushions and mattresses.
- Patent 4,698,864 of October 13, 1987 relating essentially to the possibilities of different heights of certain cells relative to each other, depending on the position of the seat; then U.S. Patent 5,052,068 of October 1, 1991 relating to a improvement equivalent to the previous one, with cells always symmetrical with eight sides forming four fins and four edges concaves in the middle of their four faces, but with shapes different; and finally the P.C.T. WO 92 / 07.492 published May 14 1992 and relating to a distribution of air or gas which may inflate said cells, through a manifold capable of distributing this air or gas in certain cells to allow pressures different, depending on the areas of the cushion or said mattress.
- a solution to the problem posed is a telescopic cell inflatable of a cushion or mattress element, consisting of a sole providing a flat lower support surface and several said cells, lying perpendicularly and fixed to said sole, arranged parallel to each other in a matrix covering the surface of the element and made of flexible material forming a tight external skin containing an internal volume of gas in each cell, each communicating with at least the volume internal of an adjacent cell; which cells are shaped like mandrel with four external edges including the four lateral surfaces are in the recessed rest position, and when a load is applied on said element by pressing on the ends of cells which then crush vertically, said surfaces deform until come into contact and lean on those of adjacent cells.
- two of the opposite side surfaces of each cell consist of three vertical sides forming in position rest, two concave edges, while the other two surfaces side of the same cell consist of two vertical sides making a single median concave edge, at least one of the surfaces lateral to three sides of each cell being arranged facing a two-sided lateral surface of an adjacent cell.
- the dimensions of said cells have a ratio between their base and their height depending on the thickness of the cushion desired, between either 37 and 45% for an average height between 95 and 105 mm, or between 57 and 65% for a height between 60 and 70 mm, and a distance between their bases of at least 8 mm, with a cell density per m 2 between 350 and 450; the angle a formed by the only two vertical sections of the lateral surfaces of each cell which they constitute is 120 ° and moreover the vertical sections of all the lateral surfaces are articulated at their lower parts on inclined sections which articulate themselves on a cylindrical base.
- At least one of said cells preferably located in a corner of this element, has a fixed inflation tip and opening into one of the external edges of said cell and located at a distance from the base of it, or in fact from the sole of the element or cushion, at least 8 mm.
- a balancing channel located at the level of the sole, that which can be obtained by absence of bonding of the skin cells thereon at given locations of their junction; in the present invention, in order to obtain the most air displacement slow and progressive possible during movements of a person on said cushion or mattress, and thus avoid instability as in some current cushions, said channel, at least in the direction of a dimension of the cushion or said mattress is such that it does not connect to the maximum that three adjacent cells in a straight line, and that any part of this channel joining two cells located on two sides opposite with respect to said dimension of the element passes at least through 3n / 2 cells, n being the number of cells occupying this dimension cushion or mattress.
- an element of cushion for example with a dimension of 400 x 450 mm, it can include 72 cells at most, arranged in matrices of 8 x 9 for example; the different skins of material, constituting the cells and the sole, are bonded together according to an equal breaking tensile force for the same sample section at least 40% of that of the only material constituting said skins, such as in particular thanks to the specific choice of said material, an example of which is given previously.
- the result is new types of telescopic cells inflatable cushion and mattress elements, having a certain number of characteristics responding to the problem posed.
- the asymmetrical shape and specific profile of the telescopic inflatable cells according to the invention allow these said cells to be more stable than in current cushions or mattresses, which ensures good stability of the load and therefore of the person who can lean on and move on it, while respecting the standards imposed in this area.
- the ten-sided configuration of all the faces of the cells constituting six concave edges instead of four, in the cells known to date, provides better support by a sort of nesting of these with each other. available in staggered rows facing a two-sided side surface of a cell, a three-sided side surface of the adjacent cell: said surfaces are then better immobilized with respect to each other and ensure better stability of the cells than in current cushions; all the more so since the ratios of the dimensions of the cells and their density to m 2 are in different percentages, which represents, for the current cushions, cells that are much more vertically elongated, and thus causing a certain instability; in addition, the minimum space retained in the present invention between said cells, which is at least 8 mm and at best 10 mm, is possible thanks to the choice of dimensional ratios as indicated above, this minimum space then being sufficiently wide, allows on the one hand, good ventilation and cleaning, and a better possibility of manufacture by dipping and pouring the product in molds.
- the choice of polychloroprene material above provides better resistance to quenching, during work and molding of said skin to produce said cells, which allows flexibility of the material, while for a lot of current cushions, the skin is quite stiff after the manufacturing; in the present invention, this flexibility is in particular obtained thanks to the minimum mineral load in the polychloroprene retained; moreover, this characteristic of flexibility and that obtained even when cold as already mentioned previously by a choice mixture of two types of elastomers, as well as resistance to breakage of the material, are retained even after aging by example for seven days at 70 ° C, with an elongation at break of more than 650%, a breaking strength greater than 15 MPa, then that under the same conditions, many other materials harden, which is annoying, on the one hand for the user and, on the other hand, during manufacture to bond the skin constituting said cells on the support sole.
- Figure 1 is a perspective view of a cousin element according to the invention in a pre-inflated situation.
- Figures 2 and 3 are side and sectional views of two adjacent cells, according to the invention, of a cushion element.
- Figure 4 is a partial view of an element of the cushion of the Figure 1 in the rest and deflated position.
- Figure 5 is a top view of the cushion portion of the figure 4.
- Figures 2 and 3 are side and sectional views of this profile of two adjacent cells 2 of a cushion element, such as shown in Figure 1, but in a deflated situation, as in the Figures 4 and 5.
- said cells 2 have therefore been represented. pre-inflated thanks to this inflation tip 7 located in the corner of the cell, itself located in the corner of the cushion element, but this toe could of course be located in the sole 3, like this exists in other cushions, although this embodiment is not not recommended according to the present invention; pre-inflation at one given pressure is, for normal use, determined in depending on the weight of the load which said element of cushion or mattress, in order to respect for example a height minimum of 3 cm as specified in French standards, when said cells are deformed to the maximum; internal pressure in these then compensate for the weight they have to bear.
- said cells thanks to the arrangement and the specific form of their surfaces which come into contact have good stability; he is evident however that if the cells did't enough swollen and did not come into contact with each other, despite their specific arrangement according to the invention, this would cause deviations from their vertical axis, therefore instability and poor comfort, and the risk of creating bedsores.
- the choice of these pressures depending on the weight of the load is determinable in a known manner, without the need to describe more in the present description.
- the base B of cells 2 can be a square from 38 to 42 mm on a side, and their height for elements of 65 mm thick cushion, and for thicknesses approximately 100 mm.
- said channel 8 as shown in FIG. 6, at least in the direction of the general dimensions of the cushion or of said mattress, is such that it connects at most only three adjacent cells 2 in a straight line; moreover any part of this channel 8 joining two cells 2 located on both sides opposite with respect to said dimension of element 1, pass to the minus by 3n / 2 cells, n being the number of cells occupying this dimension.
- the gas permeability coefficients of the neoprene thus defined is at 25 ° C for hydrogen of 10.8 x 10 -8 cm 2 / second x atmosphere, for oxygen of 3 x 10 -8 cm 2 / second x atmosphere, for nitrogen 0.89 x 10 -8 cm 2 / second x atmosphere, and for carbon dioxide 19.4 cm 2 / second x atmosphere; and at 50 ° C, the same gases with the same units, allow to obtain respective permeability coefficients of 28.5, 10.1, 3.5, and 56.5 cm 2 / second x atmosphere.
