Description

Water mattress

  The present invention relates to a water mattress.

  It is becoming more and more common to use instead of

  woolen, spring or synthetic foam, water mattresses comprising a flexible bag filled with a certain amount of water. Such mattresses provide excellent comfort to the user, without any hard point between the back or members thereof and the mattress

  since this last perfectly fits the bearing surface of the body.

  The existing waterbeds currently on the market include

  a surrounding foam frame, including the central cavity

  is intended to receive the pocket containing the water, with possible interposition

  the between the frame and the pocket, and under the pocket, a waterproof envelope

  of safety avoiding the flow of water in case of tearing of the pocket.

  To ensure a good comfort for the user, the water temperature is regulated to the desired value. For this purpose, under the pocket is disposed a heating element controlled by a thermostat whose probe

  is in contact with the pocket. The entire mattress is dressed with a coat-

cloth.

  In order to prevent the pressure of the water from deforming the foam frame, it is generally fixed, for example by screwing, on a rigid support panel. The panel is mounted on a base with structure, also covered with fabric, giving the whole appearance of a mattress

traditional on his bed base.

  Such a mattress has the disadvantage of requiring a tool for its assembly, which must be performed by a specialist, which makes it difficult to use with a bed structure or an existing bedding. In addition, in practice given the presence of the support panel, it is not possible to deeply border the sheets of the bed under

  the mattress, as such is the case with a traditional mattress.

  Finally, this structure, very bulky, is of a heavy aesthetic appearance. To avoid some of these disadvantages, it has been imagined to house the foam frame inside a cover. However, this solution is also not satisfactory because, in view of the movements of the water, there is an unattractive deformation of the foam frame whose edges have an outward arrow and whose angles back.

  The present invention aims to overcome these disadvantages.

  For this purpose, in the mattress it concerns, of the type comprising a foam frame whose opening serves to accommodate a pocket filled with water, the frame contains a rigid section extending over its entire periphery, is fixed on a support constituted by an inextensible fabric and is coated on its lateral walls with flower beds fixed, on the one hand, on said walls but also on the lower canvas support and on the wall

top of the coating.

  The structure of the foam frame, for example of polyether type, gives the shape of the mattress, maintains the water bag which is in the center of it and ensures a good comfort for the user sitting on the edge of the mattress . The peripheral profile prevents the pressure of the water

  laterally deforms the four sides of the foam frame. Finally, the defor-

  of the foam frame and the raising of its edges and its angles during the movements of the water inside the pocket is avoided by the presence on the one hand of the inextensible support fabric and, on the other hand,

sidebeds.

  Advantageously, the peripheral reinforcing profile of the foam frame is disposed inside thereof at one-third of the height of the frame considered from bottom to top. This profile can be constituted for example by four flat irons welded two by two at the level of the four

angles of the frame.

  This positioning of the peripheral profile does not harm the comfort

  when the user sits on the edge of the mattress.

  According to another characteristic of the invention, each flower bed

  lateral part comprises a foam part of the same kind as that

  frame, of the same height as the latter and intended to be fixed on it by gluing, and a part constituted by a tick fixed on the

foam by sewing.

  Advantageously, and so that the sewing threads do not cut the foam of the flower bed, a mesh with a wide mesh, made of inextensible thread and disposed between the foam of the flower bed and the frame,

is caught in the seam.

  For its part the frame is fixed by gluing on the inextensible support fabric, which is constituted for example by a coated fabric or not

or by a nonwoven.

  The support fabric and the top coating are for their part

  attached to the sidebeds by bristles.

  In any case, the invention will be well understood by means of the description

  following with reference to the attached schematic drawing showing, by way of non-limiting example, an embodiment of this mattress:

  Figure I is a perspective view, an angle having been

  ket; Figure 2 is a cross-sectional view on an enlarged scale

from one edge of this mattress.

  The mattress shown in the drawing comprises a frame (2) polyether foam of generally rectangular shape, and having a trapezoidal section, the face on the side of the interior of the frame being inclined

  from the bottom up and from the inside to the outside.

  Inside the frame (2) is embedded a reinforcing peripheral profile consisting, in the present case, of a flat iron (3). In order to allow the engagement of the flat iron inside the frame, it is

  at a horizontal incision (4) of the foam.

  As shown in the drawing, the reinforcing profile is located substantially one third of the height of the frame. The frame (2) foam is fixed by glue (5) on a fabric (6) which, occupying the entire

  the bottom surface of the mattress is made of an inextensible material.

  This fabric (6) has at least one opening for the passage of the feed son of the heating film, not shown, and son of the probe

  thermostatic also not shown in the drawing.

  The space defined inside the frame is equipped with a pocket (7) filled with water (8) with the interposition of a security envelope (9)

  between the pocket (7) and the fabric (6) and the foam frame (2).

  The side walls of the frame are equipped with flower beds (10), each of which comprises a piece (12) of foam of the same height as the side wall of the mattress on which is fixed, by stitching, a tick (13). In order to prevent the sewing thread (14) from tearing the foam (12), a mesh (15) of wide mesh made of inextensible yarn, such as polyamide 6,6, is interposed between the piece (12) and the foam frame (2), this lattice being caught in the seam of the tick (13) on

the piece of foam (12).

  Each flower bed is fixed by glue (16) against the wall

  corresponding side of the foam frame.

  Given the similarity of the assembled materials, there is excellent continuity between the frame and the flower beds. In addition, each flower bed is assembled by a fingernail (17) to the backdrop (6) and by at least one fingernail (18) to the upper covering (19). The upper covering (19) comprises, for its part, a peripheral edge (20) to which is assembled on three sides of the mattress via

  a zipper (22), a quilted tick (23).

  This mattress finally comprises, in known manner, hydraulic dampers (24) housed inside the water pocket to limit the

  movements of it inside the pocket.

  As is apparent from the foregoing, the invention provides a great improvement to the existing technique, providing a water mattress of simple structure, which has excellent mechanical properties because not deforming under the effect of the movement of the water inside the pocket, and which has the appearance and ease of use of a traditional mattress, that is to say mounting inside an existing woodwork, mounting on a base or placed directly on the ground,

  simplicity of installation and handling, and the possibility of

deny the sheets under the mattress.

  It goes without saying that the invention is not limited to the sole embodiment of this mattress, described above as an example; she

  embraces, on the contrary, all the variants.

  Thus, in particular, the section of the foam frame or the shape of the reinforcing section may be different or the faces of the foam frame facing inwards and upwards may be covered with a sheet of fabric, fixed on the support canvas at the acute angle of the base of the frame, by sewing, by welding or by gluing, according to the nature of the materials, without going out for

as much of the scope of the invention.
