Description

BEDDING PIECE SUCH AS A MATTRESS OR THE LIKE

  The invention relates to a bedding piece such as a mattress or equivalent. Bedding pieces such as mattresses, pillows or the like are already known, comprising a plurality of deformable modular elements and means for supporting the modular elements, one next to the other, arranged in rows and columns, to form a sheet, typically flat or substantially flat (in the case of a mattress) or curved (in the case of a seat cushion). In document DE 3 303 615 the support means are a plate subdivided into compartments by longitudinal and transverse partitions defining cells in which the modular elements are fixed. In document FR 2 047 088, the support means are a plate and, fixed to the latter, a peripheral belt, the modular elements being wedged against each other and against the belt. In the document FR2 592 779, the modular elements are entered axially (in the direction of normal support on the bedding element) in the meshes of a plane grid thus coming to take and fix the elements

modular by their lateral face.

  We also know different embodiments of bedding elements such as mattress, cushion, or equivalent. In document FR 2 428 999, a mattress is proposed comprising a flexible core crossed by a plurality of holes extending perpendicular to the bearing surface on the mattress. In document FR 2 084 293, it is proposed to manufacture mattresses, cushions or the like from spongy materials with an internal core of density other than that of the external shell. In document FR 2 131 448, a cushion is proposed comprising elastic points. The invention aims to propose other alternative embodiments of mattresses, cushions or the like, of the general type mentioned above. To this end, such a piece of bedding is such that the means

2650164 2

  supports are elongated members penetrating into the outer envelope of the modular elements to ensure their maintenance. In addition, the members for maintaining the rows and columns of modular elements are essentially non-intersecting, and therefore have between them

a certain independence.

  In this respect, the invention differs from the state of the art in which the retaining members extending along a line of modular elements are directly connected and secured to the retaining members extending along 'a column of modular elements. This is in fact the case when the holding members are constituted by a continuous plate or the variant where the plate

  is discontinuous in the form of a grid.

  The invention offers in particular the advantages deriving from this relative independence of maintaining in the directions of the lines and the columns respectively. Other features of the invention will result from the

  description which will follow with reference to the accompanying drawings in which:

  - Figure 1 is a partial top view of a conforming mattress

  production of modular element retaining members.

  - Figures 13A and 13B are two same cross-sectional views of a mattress or equivalent according to the invention illustrating the possible

  deformation of a holding member.

  - Figures 14, 15, 16, 17, 18 and 19 are six schematic views in partial cross section of a mattress according to the invention illustrating various variants of holding members and modular elements. - Figures 20A, 20B, 20C, 20D and 20E are five schematic cross-sectional views of alternative embodiments of holding members. - I.es Figures 21A, 21B, 21C, 21D and 21E are the elevational views of the holding members shown in views 20A, 20B, 20C, 20D and E. The invention therefore relates to a bedding piece 1 such that a mattress, a cushion or any part of equivalent function, that is to say being in the general form of a plane or a sheet having a certain thickness; intended to receive on one (at least) of its

  large faces 2 the body or part of the body of at least one user.

  This piece of bedding i is intended either to be used alone, for example while resting on the ground, or to be incorporated in a piece of furniture such as a bed, bench, seat, etc ... thanks to a box spring or more generally a appropriate support 3. For example, in Figure 4 is shown a cushion 1 forming the back of a motor vehicle seat.

2650164 4

  Consequently, the shapes and the dimensions as well as the consistency of the bedding piece 1 are adapted according to the use and the destination which are given to it. For example, the. outer shape is rectangular for a bed; square, rectangular, circular or other for a cushion. It is single or two-seater. For a bed, the general shape is flat (Figure 1). On the contrary, it is curved for a car seat or the like (Figure 4). The bedding piece 1 can also form an assembly having a certain rigidity or, on the contrary, be foldable or rollable (for example for applications intended for the open air). The bedding piece 1 can also have a degree of comfort and softness (due to its axial elastic deformation) always greater or less depending on the use which is given to it. The bedding piece 1 can be similar in all its places or, on the contrary, present certain differences in shape, size, consistency or other. Those skilled in the art can transpose the technical solutions described here to the specific needs of the

  piece of bedding depending on its destination.

  The bedding piece 1 firstly comprises, on the one hand, a plurality of modular elements 4, capable of being elastically deformed, to a certain degree, in particular at least axially along their axis 5. It then comprises and secondly, support means 6 with lesque] s cooperate the modular elements 4 so as to ensure their transverse maintenance parallel to the plane or the sheet of the bedding element 1. In this way, the modular elements can be , in the bedding piece 1 made, placed next to the

  others by being arranged and arranged in row (s) 7a and in column (s) 7b.

  In general, i] is provided, for the same piece of bedding 1, several rows 7a and several columns 7b. However, the invention also relates to cases where a piece of bedding 1 has only a single row 7a and / or a single column 7b. In general, the rows 7a, the columns 7b, extend, respectively, substantially parallel to one another (for the rows or the columns) and substantially

  orthogonally to each other (for rows and columns) .-

  However, the invention also relates to the cases where the lines 7a, respectively the columns 7b, are not parallel to one another as well as the cases where the lines where the lines 7a and the columns 7b are not orthogonal to each other. It should also be noted that this polymorphic character uncovers the implementation of support means 6

2650164 5

  exhibiting a certain independence between them, as is mentioned. The qualifiers for * line 7a? and "column 7b", respectively, are only intended to distinguish a direction relative to a direction which intersects it, in particular orthogonal. However, in general, the structure of a row 7a and that of a column 7b can be,

  without other, inverted. For this reason, the description refers

  either on a line 7a or on a column 7b, except when a

  distinction between them is necessary.

  In the text, the term “axial direction” of the modular elements 4 is understood to mean a direction extending along or parallel to the axis 5 which is perpendicular or substantially perpendicular to the large face 2 at the location of a modular element 4. The transverse direction of a modular element 4 is understood to mean a direction orthogonal to the axis 5. In particular, the transverse direction is in line or in column, respectively, depending on whether it extends in the direction of a line 7a or column 7b. Conventionally, the upper face of the bedding piece 1 means the large face 2 on which a user is intended to rest. The large opposite face 8 is then qualified as the lower face. Furthermore, the bedding piece 1 is limited, at the periphery and between the two faces 2, 8 by an external edge 9. This external edge / 9 has, in elevation, a shape corresponding to the outline of the bedding piece 1: rectangular, square, polygonal, circular or other. The modular elements 4 adjoining the edge 9 are qualified as exteriors and those which are not contiguous to the edge 9 are qualified as interiors. All of these

  definitions are for the sole purpose of allowing use description more

easy of the invention.

  According to the invention, the support means 6 are elongated members penetrating into the outer casing 10 of the modular elements 4, so as to maintain it. In addition, these elongated members for maintaining the rows and columns are essentially non-intersecting

between them.

  The term “elongate support means 6” means a member extending mainly along an axis 11 (FIGS. 21A to 21E), this including various possible shapes in cross section (figures

265 0 164 6

  A to 20E), constants or as well as forms which can vary along

of axis 11 (figure 16).

  The axis 11 (or the different axes 11 of the different support members 6) is generally parallel to the faces 2, 8 and orthogonal to the axis 5. The different axes 11 define the different lines 7a and columns 7b. The term “outer casing 10” of a modular element 4 is understood to mean the outer surface in which the modular element 4 is entirely included. This outer casing 10 is either completely the same external face of the modular element 4 (FIG. 5), or incorporated

  of only part of this outer face (Figure 6).

  By non-intersecting holding support members 6 is meant the fact that the support members 6 of the rows 7a and columns 7b are spaced apart from one another, do not meet, and do not form knots

  such as those of a grid or a mesh, let alone a plate.

  This non-intersecting nature of the support members 6 of the modular elements 4 in rows and columns 7a, 7b. results in a certain independence of the support members 6, therefore of the modular elements 4,

between them.

  According to a possible alternative embodiment, a modular element 4 is made up, in whole or in part, of a block of plastic foam,

  deformable. This block is homogeneous (Figure 5) or heterogeneous (Figure 7).

  For example, it may include different parts (12a, 12b) secured to each other corresponding to different density or hardness or elasticity. According to another possible variant, an element 4 is constituted by a continuous and deformable wall 13, shaped to define an internal space filled, at least partially with filling content 14. For example, the wall 13 is made of material

plastic sheet, or fabric.

  The content 14 is air, plastic foam material, a plurality of pieces such as balls, a filling material based on fabrics or cellulose or equivalent or the content 14 is constituted by one or more springs . In the variant of FIG. 6, the modular element 4 has a wall 13 and, on the underside 8, is placed a valve so that the internal space at

2650 164 7

  the wall 13 can be inflated with air, the degree of filling - that is to say the air pressure - defining the degree of hardness or

  elasticity of the modular element 4.

  A modular element 4 can have in elevation (that is to say seen parallel to the axis 5) an external curved contour, circular or elliptical, or polygonal, square, rectangular or other. In axial cross section (that is to say by a plane passing through the axis 5) a modular element 4 can have a square, rectangular, polygonal, circular, elliptical external outline, of more or less tormented shape. In this regard, the substantially cubic shapes shown in the drawings are by no means exclusive although

  that they may correspond to a possible embodiment.

  In the case of such a cubic or pseudocubic shape, a modular element 4 is defined by individual elementary faces upper 15, lower 16 and lateral 17 and 18 (respectively along lines 7a and columns 7b), faces 15 and 16 being coplanar with the respective faces 2, 8. With a modular element 4 of generally spherical or pseudospheric shape, all these faces

  elementary are an extension of each other.

  The large upper face 2 is shaped, in general and locally, as a function of the destination of the bedding piece 1. For example, it may have protruding reliefs 19 and / or recesses 20 (FIGS. 6 and 7). For this purpose, it can be the same for elementary faces

15.

  Also, a modular element 4 may have on its lateral face 17, 18 at least one recess and / or a projection 21 capable of cooperating with at least one projection and / or a recess 22 of at least one adjacent and adjacent modular element 4 in particular in order to avoid an excessive relative axial offset of the modular elements 4 with respect to each other. The modular elements 4 of the same piece of bedding 1 can all be identical or similar to each other or, on the contrary, be different. Their dimensions (axially and transversely) can vary widely, the lower limit being given by the need to allow the penetration of non-intersecting holding members 6 and the upper limit being given by the very plurality of elements

2650 1 6 4 8

  composing the piece of bedding. For example, modular elements 4 can be inscribed in a cube of the order of five to ten

  centimeters aside, these values being only indicative.

  The modular elements 4 can be deformed, at least parallel to the axis 5, with a certain degree (corresponding to the local hardness or softness of the bedding piece 1) in the case where an external stress (such as the weight of the body) is applied to them. This deformation is elastic, the modular elements 4 returning or tending to return to their initial state and dimension when the stress ceases. Where appropriate, the modular elements 4 also have a certain deformability in

transverse direction.

  The modular elements 4 can be the subject of other alternative embodiments. The bedding piece 1 comprises at least one support member 6 per line 7a, per column 7b of modular elements 4 from one edge 23 to the opposite edge 24 of the sheet -related by this line 7a, this column 7b of modular elements 4. The two edges 23, 24 belong to the edge 9. These two opposite edges 23, 24 are opposite one another and generally parallel to each other. According to the invention, there is therefore, for a line 7a or for a column 7b, either a single support member 6 (FIGS. 5, 6, 9A, 9B), or several support members 6 (FIG. 17). Or, again, there is a single support member 6 for a line 7a and several for a column 7b or vice versa (Figures 7, A, 10B, 15). It is clear that for the same piece of bedding 1 certain lines 7a, or columns 7b may have a support member 6

  single and some others with multiple support members 6.

  In the meaning of the text, the expression “support member 6” means the functional assembly going from one edge 23 to the other edge 24 that this assembly

  functional forms a single-piece structural unit or not.

  The modular elements 4 are locked in longitudinal sliding, in a removable manner, on the support members 6. The removable nature allows the assembly, the disassembly, as well as the replacement of all or

  part of the parts making up the bedding part 1 according to the invention.

  And, in addition, the invention also relates to the bedding piece 1 in the state

2650 164 9

  disassembled. The term “longitudinal sliding blocking” is understood to mean the sliding blocking along an axis 11. of the support members 6. This longitudinal sliding blocking can be achieved either by a positive blocking on the support members 6 by the support members 6 themselves and / or blocking members 25 associated with them. This is particularly, but not exclusively, true for modular exterior elements 4. For example, the support member 6 takes the form of a firm strip on itself, without end, which prevents the sliding of the modular elements 4 (FIGS. 12A, 12B). Or again, the support members 6 comprise on the edges 23, 24, that is to say on the edge 9, locking members 25 or individual members such as stop washers removably fixed on support members 6 rod-shaped (FIGS. 9A, 9B), or common to several (respectively all) the lines 7a or columns 7b such as lateral cheeks 26 (FIGS. 10A, 10B) or also to several lines 7a and columns 7b such that a frame 27 (Figures 11A, 11B). This arrangement can also apply to interior modular elements 4 in particular in the case where a modular element 4 is missing (.figure 9B). This longitudinal sliding blocking relates to a single modular element 4 or even all the modular elements 4 which can then have a reserve 28 provided for this purpose which can

  receive a blocking device (figure 19).

  As a variant, especially for the interior support elements 4, the positive locking With longitudinal sliding on the support members 6 is obtained by wedging between two modular elements 4 located on either side. In fact, it is not always essential to provide a blockage With direct longitudinal sliding of the interior modular elements 4 on the support members 6. On the contrary, it may in certain cases be desirable for the interior modular elements 4 to be able to slide longitudinally with a certain degree on the support members 6 in particular in the event of a strong axial deformation of the modular elements 4, these being crushed axially which causes their expansion along the axes 11 which pass through them, this expansion acting on the neighboring modular elements 4 by compressing or even moving them. In any event and even if a certain axial longitudinal floating along the axes 11l may be admissible or desirable in response to a suitable external stress, the means and members 6 must, fundamentally, maintain the modular elements 4 so that the part of bedding 1

2650 164 10

  maintains a certain overall cohesion.

  According to a possible variant, a support member 6 is continuous from one edge 23 to the opposite edge 24 of the sheet (FIGS. 9A, 9B, 1OA, lOB, 11A, 11B, 12A, 12B). According to another possible variant, a member 6 is discontinuous from one edge 23 to the opposite edge 24 of the sheet and consists of a plurality of separate elementary support members 29 (FIGS. 6, 14, 15, 16, 17, 18) . This latter variant (discontinuous support members 6) may itself be the subject of several sub-variants: either two separate elementary support members 29 are adjacent to each other (FIGS. 4, 15, 16); or two separate elementary support members 29 are spaced from one another along their axis 11 (Figures 6, 17, 18). Either two adjacent separate elementary support members 26 are independent of one another (FIGS. 6, 17, 18); or two adjacent elementary support members 29 separate elementary are connected to each other. In the latter case, the connection between two elementary support members 29 is either rigid, or with one or more degrees of freedom. In the case of FIG. 15, the elementary support members 29 are associated with each other by hinges 30, situated substantially between two neighboring modular elements 4 but which can also be located inside a modular element 4. no hinges 30 (i.e. their spacing) can be identical or a multiple of that of modular elements 4 that is to say that a hinge 30 can be provided that all the several modular elements 4 In FIG. 16, the elementary support members 29 are associated with each other by fitting, by means of a stud 31 with which they are provided at one end penetrating into a sleeve 32

provided at the opposite end.

  According to a possible variant, a support member 6 has a general shape

  rod (Figures 9A, 9B, 10A, lOB, 14, 15, 16, 17, 18, 20A, 21B).

  According to another variant, it has the general shape of a plurality of fine rods or needles placed side by side in parallel (FIGS. 20E, 21E). According to another possible variant, it has a general shape of band or strap or equivalent (FIGS. 11A, 11B, 12A, 12B, 20C, 21C). According to another possible variant, it has, more generally, a generally profiled shape with a constant cross section (Figures 20D, 21D) or not (Figure 16). For example, it has a contoured shape like a flat iron (figures

2 650 164 11

  B, 21B), a star (Figures 20D, 21D), a triangle (Figure 16).

  A support member 6 is either rigid and substantially undeformable so that there is no substantial modification of the relative position of the modular elements 4 relative to one another when an external stress is applied to them. Either the support member 6 is self-supporting while being able to be deformed under the action of suitable external stresses. In the latter case, it participates in a certain hardness or softness of the whole piece of bedding 1. This is illustrated by FIGS. 13A and 13B in which it is illustrated that a piece of bedding originally flat (FIG. 13A) is deformed when subjected to the stresses represented by the arrow F this mistletoe causes a certain deformation of the support member 6. Or, again, the support member 6 is flexible in the manner of a strap and it is stretched in the normal position mounted being, by

  example closed on itself in an endless loop.

  Thus - as a result of the above, a support member 6 constitutes a part forming either a limited section, going from one edge 23 to the other 24 or not (case of a discontinuous support member 6) or

an endless loop.

  There is also provided at least one plane or ply 33 in which are placed the support members 6 of the lines 7a and / or columns 7b of modular elements 4. This plane or this ply 33 extends substantially parallel to the upper face. 2 (or to the lower face 8 substantially parallel to the upper face 2) while being placed between the two faces 2, 8. As a variant, the support members 6 are placed in several planes or layers 33, for example in two planes or sheets extending substantially parallel to each other. Preferably there is at least one plane or ply 33a for the support members 6 of the lines 7a and at least one plane or ply 33b for the columns 7b. such a structure is clearly visible in FIGS. 9A, 9B, 1IA, 10B, 11A, 11B, 12A, 12B, 14, 15, 16, 17. In the case of FIG. 18 all the support members 6 are placed in the same plane or tablecloth 33. As follows from the above, the planes or tablecloths 33 containing the means of supports 6 are included in the thickness

  modular elements 4 between the two opposite faces 2, 8.

  A row or column 7a, 7b of modular elements 4 may comprise

2 650 164 12

  several support members 6. These are then arranged, for the successive rows or columns on the same plane or sheet, such as the plan or sheet 33c of FIG. 15; and / or on several planes or layers 33d extending substantially parallel to one another and to the faces 2, 8 (FIGS. 10B and 17); and / or on several planes or sheets 33e extending substantially parallel to one another and substantially transversely to the bedding piece I itself, that is to say perpendicularly or substantially perpendicular to its faces 2,

8 (Figure 17).

  Naturally the various solutions and variants can be

combined together.

  Furthermore, the lines 7a and the columns 7b of modular elements 4 comprise several support members 6 arranged for the lines 7a on at least one plane or table 33a, for the columns 7b on at least one plane or table 33b, the plans or layers 33a, 33b of lines and

  columns being merged or extending substantially parallel.

  between them as it results from the above. In Figure 18,

  the two planes or layers are merged in the same plane or layer 33.

  In this case, the support members are discontinuous. In the case of FIGS. 9A, 9B, 11A, 11B, 12A, 12B, 14, 15, 16, the planes or sheets 33 are spaced from one another, being substantially parallel to the faces 2, 8. As a variant , for rows 7a and / or columns 7b, there are several planes or layers, as already indicated (figure 17 by

example).

  To allow the modular elements 4 to be mounted on the support members 6, it is provided that an element, a modular element 4, is provided on its lateral face 17, 18 with at least one hole or recess 34 for association with a member. support 6. For example, an interior modular element 4 is provided on its lateral face 17, 18 with at least four holes or depressions 34 or set of holes or depressions 34 extending in two directions substantially orthogonal to each other. The notion of hole or depression 34 covers any shape given to the modular element 4 in particular on its lateral face 17, 18 so that a support means 6 can be inserted into the outer casing 10 on a cardboard axial length and be housed with a certain suitable adjustment so as to allow, by itself, the maintenance of the modular element 4 on

2650164 13

  the support member 6. It goes without saying that the holes or depressions 34 have a suitable shape and generally complementary to that of the holding member 6. In addition they extend over a certain length in axial direction along the axis 11 so that the maintenance is effective. This adaptation also relates to the arrangement of the holes or recesses 34 which open, on the lateral faces 17, 18, and

  not on the upper face 2 or the lower face 8.

  According to a possible alternative embodiment, the holes or recesses 34 of the modular elements 4 are through and there is associated with them support members 6 continuous. This variant is typically that of FIGS. 1, 5,, 7, 9A, 9B. According to another possible variant, the holes or depressions 34 of the modular elements 4 are blind and there is associated with them discontinuous support members 6. This variant is typically that of FIGS. 6 and 18. Naturally all the solutions can be combined with each other, that is for the lines 7a,

  either for columns 7b or for both.

  The holes or recesses 34 either come from manufacturing, or are produced after, in particular by drilling or recess and in particular

  insertion & force of the support member 6 in the modular element 4.

  They can be produced as a result of a suitable shape given to the lateral faces 17, 18 (FIG. 6). Where appropriate, the holes or depressions 34 may have a shape allowing the housing of the holding members 6 but also of the locking members 25 (FIG. 19). The holes or recesses 34 are adjusted so as to ensure, preferably, a certain friction of the modular element 4 on the retaining members 6. If necessary, the joining is rigidly and non-removably ensured by additional bonding. The holes or recesses 34 are spaced from the upper face 2 so as not to affect it. Preferably they are removed from this face as much as possible so that the user does not feel the hardness of the means

supports 6.
