Definitions
- the present invention relates to a support that can serve as a mattress, cushion or padding consisting of cells, in the form of balloons or cells inflated by a fluid, connected or not connected by the base so as to form the same volume entity of fluid whose nature is defined according to the needs and contained in the various cells, which are arranged in such a way that their number or density per unit of support surface is as low as possible while providing in the operating position a support surface the most uniform adapting to the model of the supported body, once correctly filled
- This support can be used for medical use such as anti-decubitus mattresses and cushions and protective padding in particular such as dorso-lumbar supports or for fragile products BACKGROUND TECHNOLOGICAL
- These types of support are already known in principle which is to marry at the level of their fa this support what they must support by offering the same reaction whatever the degree of depression in the support by the hadopressure thanks to the mter-commumcantes cells, as described by JAY on cushions in US 47266624 US 5018790 and US 5
- the present invention proposes to provide solutions which make it possible to remedy the drawbacks of the previously known methods. Consequently, the subject of this invention is the design of mattresses, cushions, padding for medical use, reusable packaging of fragile products, and anti-vibration support with expandable cells.
- an upper sheet generally flexible, in shape comprising expandable cells, intercommunicating or not, capable of expansion during their filling with a fluid
- a cell at rest seen in cross section at the level of the body is delimited by at minus two perimeters interior and exterior partly virtual, concentric inscribed on envelopes of indifferent square, pentagonal, octagonal, circular, irregular shape, where the slits, faults or crevices consist essentially of walls, more or less substantially close, parallel or not, with draft or undercut, straight, concave, convex or broken, connecting the outer perimeter to the inner perimeter, for example the adoption mainly of a broken line to join the periphery to the central zone of the balloon or cell conferring a certain advantage characterized by that the portion of the cell wall joining two points each located on one of the perimeters can be strictly in a straight line under the condition DESCRIPTION OF THE INVENTION
- FIG. 1 is a 3/4 plunging view of an upper sheet made up of substantially identical expanded cells, such as those of FIGS.
- a support or padding is produced, composed in particular of a top sheet 1, in general, flexible, in form comprising expandable cells 3, which can be interconnecting, capable of expansion when filled with a fluid such that a cell at rest seen in cross section at the level of the body is delimited by at least two internal perimeters 6 and exterior 7 partly virtual, concentric inscribed on envelopes of indifferent square shape 16, pentagonal 19, octagonal 17, circular 18 irregular 15 and 20, where the slits, faults or crevices consist essentially of walls more or less substantially close, parallel 4 or no, with draft 8 or against draft 9, straight lines 21, concave 10, convex 11 or bri 12a and 12b, connecting the outer perimeter 7 to the inner perimeter 6, 1 adoption by way of nonlimiting example mainly in the form of a line b ⁇ s ⁇ e 14 to join a point 22 of the periphery 7 to a point 23 of the central zone 6 more or less close to the axis 24 of the balloon or cell (f ⁇ g.3 // f ⁇ g 2 // f ⁇ g
- a cell 3 (fig 1 and fig 18) has from top to bottom along the longitudinal axis 24 an apex 25 in the form of a dome or of domes when the cell is filled with fluid and when the cell is at rest the walls on the external envelope generally join gently the central point of this vertex preferably situated on the longitudinal axis, a body 26 object of the invention, a foot 27 of
- the first (fig 2) is described as a star formed by eight branches 5 attached to a virtual central element 6 and contained in an outer envelope 7 and the second (fig 4a) as a four-pointed star ending at the four corners of a square envelope we see that from the distal end of the branches to the proximal part the walls of the branches 5 are in a straight line 13
- the advantage by comparison of the present invention is due to the replacement of these straight walls (fig 2, fig 4a, fig 12,1a right being the shortest path from one point to another, by a flat at 29 (fig 4b) or by walls of the longer cell, for example in a broken line 14 between the points 22 and 23 each situated on one of the concentric perimeters 7 and 6 portions of cell walls which follow in their centripetal path the path of the outer envelope and reveal (fig.
- the sagittal plane of a crevice is the plane located halfway between the opposite walls of a crevasse, in general as we will see later this plane is not necessarily radial
- the gain in perimeter of the inflated fluid cell is substantially 3% to 25 % in practice, and up to 40% in theory as we will demonstrate later, in the case of
- 1 external virtual envelope 7 outside of the irregular section shapes will have, in order of preference, a square section 16 circular 18, pentagonal 19, octagonal 17 and according to the free use of the product in practice.
- the number of crevices is limited by their width at the level of the inner concentric perimeter, by the thickness of the wings at this level and by the length of the inner concentric perimeter, as well as by the thickness of the material constituting the cell of its mechanical qualities. and its implementation characteristics
- the difference between According to the invention, the prior art and the invention can be demonstrated in the following way.
- the schematic shape of a male mandrel wing used for manufacturing cells by dipping for example, and consequently this cell wing at rest is the part between two successive or contiguous crevices, is often represented by a triangle (fig 3) (fig 6) (fig 7) (fig 9) (fig 10) (fig 11) (fig 15a) (ig 17) a quadrilateral ( fig 4b) (fig 5) or an at least substantially triangular shape whose apex is on the side of the inner envelope and the base of the rib of the outer envelope
- a wing of a cell at rest comprises te at least three faces including at least two faces each from the walls of two successive crevices and one face at least along the path of the outer envelope, this third face has at least one flat 29 on part of its path along the outer casing 7
- the cells corresponding to the description of Figures (6) - (7) - (9) - (10) - (11) would be more efficient by expansion in wedge along the diagonals, avoiding hollows in the support at the intersection of the rows cellular mter, thus offering a most uniform support surface, these rows correspond to the assembly areas (gluing, welding or other) of the upper 1 and lower sheets 2
- the external virtual envelope 7 for anti-decubitus supports can have ten to a hundred millimeters approximately in cross section, the walls of the crevices being able to be spaced approximately two to twenty millimeters, 1 thickness of the wall of a cell can vary from a half to two millimeters approximately We can admit for an anti bedsore support or a padding an even number of crevices between four and eight ten approximately, 1 longitudinal central axis 24 can be an axis of symmetry We can accept for a anti bedsore support or padding an odd number of crevices between at least three and approximately nine, the possible plane of symmetry passing through the
- the invention can be adapted to any form of cell, from which we mainly retain and for the example, cells comprising a flat 29
- the resting cell the cross section of the body 26 of which is seen in cross section (FIG. 3) of the walls with an outer shell 7 which is substantially circular.
- the resting cell the cross section of the body of which is seen in cross section of the walls with a substantially square outer envelope comprising six wings with parallel walls and six crevices with parallel walls, the whole being arranged by comparison with two combs with three teeth joined back on the back the three teeth of the two combs representing the six wings, therefore on each of the two opposite faces of the outer envelope are visible two crevices of each side of a central wing, the two crevices themselves being surrounded by two wings parallel to the first central wing, the external faces of the two wings surrounding the first being themselves constitutive of the external envelope the openings of the last two crevices with walls parallel being arranged on the midpoints of the two other sides opposite and perpendicular to the wings arranged on the first two sides of the envelope, the wings with parallel walls being characterized in that their third face following the path of the outer envelope is made up of a flat or six flat, the cell being made up of six crevices with parallel walls according to the invention we will retain the previous cell to which on the
