Description

Water cushion, in particular pillow Water.

The invention relates to a water cushion, in particular to a water pillow, which is provided with filling of two types, that is, with a filling of flexible material and compressible and with a separate liquid-refillable chamber, in water concrete

A water cushion of this type is known as example by PCT publication WO 96/27315. This water cushion known, which serves specifically to relieve the pain of head and / or neck, comprises a relatively volume filling large of a flexible and compressible material, for example a fiber material, as well as, seen on the floor from above a cushion of water or a water chamber placed under this fill and of relatively small volume compared to him.

The individual components of this cushion water are resiliently bound together for example sewn, glued or welded, depending on the material used.

Another water cushion is known from the DE document 689 24 428 T2. This water cushion also comprises a filling of relatively large volume of a flexible and compressible material, for example an appropriate fiber material, and a water cushion or a water chamber placed below or partly included in your interior, which compared to the compressible material has a considerably smaller volume.

Also in the case of this water cushion known, the individual components are expensive interwoven or interwoven, as well as bound together in a certain way mode separately, sewn, glued or welded.

In particular, of the union in some way by separated from the individual components from each other in the case of known water cushions, there are disadvantages that in case necessary these can only be cleaned, i.e. washed as a unit. The washing temperature depends on the sensitivity to the temperature of the materials used and since In general the material for the water chamber is plastic, a cushion known type cannot be washed at high temperatures, in particular not at boiling temperature (95 ° C). However a wash of this type at high temperature, in particular at the temperature of boiling, it is often essential for hygienic reasons, for example in case of medical use.

In the closed model, for example sewn, neither it is possible to modify the amount of material filling compressible as desired or needed.

Direct contact under certain circumstances between the compressible filler material and the chamber material of water can cause long-term problems, for example due to to the diffusion of plasticized. This problem can only be Solved using superior quality material and more expensive.

The document NL-C-1 007 021 describes a pillow with several cameras with isolated sections of different hardness for support the head as ergonomically as possible. Like in PCT publication WO 96/27315, this cushion comprises a padding of relatively large volume of a flexible material and compressible, for example a fiber material, as well as, seen in plant from above a water cushion or a water chamber placed under this padding and relatively small volume in comparison with the. The padding is placed in several chambers parallel individual, among which there is a water chamber as well as an additional camera in the transverse direction.

The individual components of this cushion Water found inside a common envelope. The structure is complicated and here there are also the drawbacks cited above regarding cleaning, etc.

In the document DE-A1-197 53 765 describes a pillow with side headrests. These headrests too can be filled, among others, with a fluid, specifically with air or water They are provided with access openings that close by means of a zip closure. The zipper closure of each headrest is loose outward, which harms comfort when leaning and sleeping.

The document US-A-4,780,921 discloses a cushion of several chambers, whose enclosure is closed by means of a closure self-adhesive or a velcro closure. Closures of this type lose often its holding capacity after few washes, in particular in washings at boiling temperature.

Finally, the document US-A-4,501,034 shows a pillow with one or several inflatable chambers together with material chambers of filling.

Moreover, the invention is based on the objective of forming a water cushion of the type previously cited, in which at least partly the inconveniences are avoided cited above from known water cushions and in particular, in which parts are not loose outwards metallic that under certain circumstances harm, among others, comfort when supported, for example, zip fasteners, but in which, however, access to the individual pad chambers.

To achieve this goal, the present The invention proposes, according to claim 1, a water cushion, in particular a water pillow, with a material filling flexible and compressible and a refillable independent chamber of liquid, namely water, in which the flexible material and compressible is in a separate case separated from the water chamber, in which the sheath of flexible material and compressible and the water chamber are arranged together in another common case and at the same time, are separated from each other by this same common case and in which all covers are provided with openings that can be closed. The water cushion according to the invention is characterized in that the common case is configured of so that, after introducing the cover of the flexible material and compressible, is reversible, so that the closure that encloses the flexible and compressible material sheath on the common sheath, it turns  towards the inside of the common sheath.

Since after introducing the material cover flexible and compressible (hereinafter called "material of padding ") the common cover is reversible so that the closure which encloses the cover of the filling material in the common case is turn towards the inside of the common sheath, this closure, after turn around correctly, you can no longer see outside and in particular, due to the material of the common sheath that is in between, it is considerably less noticeable, so that the comfort when supported. This is especially applicable when Use a zip closure.

In the cushion according to the invention, the covers for the flexible and compressible material and for the water chamber they are arranged in a common sheath, however they are separated at at the same time from each other for this common case. Since you can have access to the cover for the filling material and the cover common by means of openings that can be closed, it is possible also access each of the fillings (filler material and water chamber) In this way you can also change the amount of filling of the filling material and / or the filling quantity of the Water chamber as desired or necessary. In addition it is also possible to remove the water chamber from the common case for cleaning, so that it can also be washed at boiling temperature If you have the right material. This guarantees a maximum in hygiene and cleaning.

Other advantageous configurations of the invention they appear in the subordinate claims.

Therefore, it is preferred to access the openings of all covers, that is, of the material cover (of filling) flexible and compressible and of the common cover for the cover of the filling material and for the water chamber, by means of zipper closures. Zip closures are easy to actuate and offer a safe and reliable and unalterable closure by the time, unlike for example the adhesive closures.

The common case, which contains the material of filler and water chamber, is preferably collected in a holster antiallergic This antiallergic cover is, so to speak, the wall outer or outer layer of the entire water cushion and serves to improve comfort, since you can also, for example, cushion (glove, swell, etc.). In addition, the antiallergic cover it is used to insulate possible materials from the water cushion allergens

The anti-allergic cover can also be opened and close, in particular by means of a zip closure, to be able to introduce the common case with filler material and the chamber of water, as well as to be able to easily remove the common cover.

The water chamber has a configured closure especially as a threaded closure for filling and emptying. From this way, depending on the amount of filling it is possible to regulate the degree of hardness of the water chamber.

Seen from above the water cushion It has a rectangular shape with two long sides and two narrow sides, in which the zipper closure of the common case that houses the cover with the filling material is located on one side Narrow and zipper closure of the common case that hosts the Water chamber is located on one of the long sides. The cover that picks up the filling material presents a certain stiffness by itself and therefore it is manageable without any problem and can be introduced also without problem on one of the narrow sides of the. sheath common. Something different happens with the water chamber, which has much less form resistance and therefore it is due preferably introduce in the common case in all its extension to along one of the long sides, which makes this possible advantageous configuration.

The cover that cuts the filling material is that is, the flexible and compressible material also presents a Zip closure at least on one side, whereby You can open and close. In this way, adding or removing the flexible and compressible material you can change the amount of filling and with it the degree of hardness.

All covers are preferably composed of a washable material at boiling temperature if necessary, so the water cushion as a whole is hygienically washable.

The water chamber is preferably surrounded by an additional waterproof waterproof case, to be able to collect the water that comes out of the water chamber in case of permeabilities

In the following description of an example of configuration indicated other details, aspects and advantages of the present invention by means of a drawing.

It shows:

Fig. 1 a longitudinal section of an example of configuration of a water cushion according to the invention;

Fig. 2 a cross section of a cushion water according to the invention and

Fig. 3 an enlarged sectional view of fig. one.

In the drawn view a structure is presented multi-layer with a total of 2 water cushions drawn. The structure is mainly composed of a cover exterior antiallergic 4, which is the outer cover of the water cushion 2 and which is accessible from a long side (comp. Fig. 2) through a zipper closure 6. The anti-allergic cover 4 can thus open and close along the entire length of a long side by means of zip closure 6. In this way, with the closure 6 open zipper can be inserted and removed from the case antiallergic 4 a common cover 8 (comp. fig. 3).

The common case 8 is configured mainly in the form of two bags 10 and 12, which are surrounded by a common outer sheath 14 and separated by a wall of separation 16. One of the bags, in the drawn view the bag 10, serves to accommodate a flexible and compressible material 18 (filler material) with some form of fleece or flake or strands of an appropriate material, especially polyester. This material of padding 18 is in a separate case 20, that is, own, which specifically in fig. 3 is only represented by one individual line ,, as it consists solely of a material or fabric with a correspondingly thinner thickness. This case 20 is  accessible by the narrow side of the water cushion 2 - which as shown in the views of figures 1 and 2, seen in plan from above it is essentially rectangular in shape with two sides long and two narrow sides - by means of a zip closure 22, in which with the zipper closure 22 open you can extract or add filling material 18, in order to regulate the hardness and / or comfort of the water cushion 2.

The water chamber 24 found in the other bag 12 is mainly composed of a waterproof case water 26, which is also surrounded by a safety cover waterproof (not represented in more detail in the He drew). A closure 28, specifically a threaded closure, as already known for water beds, serves to regulate as desired the water chamber filling amount 24.

As already described, bag 12 and of this it forms the water chamber 24, is separated from the bag 10 and from this shape of the filling material 18 by means of the wall of separation 16 from the common sheath 8.

The common cover 8 can be opened and closed by middle of another zipper closure 30, to introduce the chamber of water 24 in the cover 8 or to remove it from it. In fig. 2 east Zip closure is on the same long side as the Zip closure 6 of anti-allergic cover 4, but nonetheless It can also be found on the opposite side.

The water cushion 2 according to the invention is configured as follows: with zipper 22 open, the filling material 18 is introduced in the bag 10. A then, the whole filling material is turned over 18 in the bag 10 and common wrap or common sheath 8, so that the zipper 22 already closed turn towards the inside of the common case 8, that is, it is no longer facing outwards. East process of turning does not affect the bag 12 that collects the water chamber 24, that is, after turning the common case 8, the water chamber 24 can be introduced in the bag 12, then of which the zip closure 30 and the common cover 8 are closed with the filling material 18 and the water chamber 24 form a unit, which can be introduced back into the antiallergic cover 4, after which after closing the zipper closure 6 of this, the water cushion 2 as a whole is obtained according to the invention.

The following describes in more detail the turning process after introducing the filling material 18 in bag 10:

Assuming the situation in fig. 1 - but without antiallergic cover 4. Also assuming that the water chamber 24 not yet found in bag 12. Zip closure 30 for close the common cover 8 is open, the filling material 18 It is inserted in bag 10 and its zipper 22 closed. The lower part 8a of the common sheath 8 (fig. 3) is pushed with the zipper closure of fig. 2 opened first towards the right and then up on the bag 10 with the material of padding 18, as if the bag 12 that collects the chamber of water 24 in fig. 2 was configured above the material of filling 18, whereby the separable wall 16 when performing the Bending in a way is "dragged." In this process of bending or turning is also reversed the closure of zipper 22 located on the narrow side of the case common 8 and thus remains on the inside of the case common 8. Then you can enter the water chamber 24 and Zip closure 30 can be closed.

The water cushion 2 according to the invention can to be considered practically configured in a modular way, it is that is to say, it is composed of the common case 8, which has both bags 10 and 12 separated from each other, in which they can the filling material 18 and the water chamber 24 are introduced. Individual bags of common case 8 can be opened and closed independently by means of zip fasteners 22 and 30, of so that if desired, the filling material 18 can be extracted and / or the water chamber 24. It should also be noted that the bag 10 for the filling material 18 has a closure of zipper on at least a part of one of the side walls, if necessary, to be able to extract or add material from filling.

Because the two main components of the water cushion 2, that is, the filling material 18 and the chamber of water 24, can be extracted from the common sheath 8, there is the possibility of being able to wash at least the common cover 8 so hygienically appropriate also if necessary at room temperature boiling, assuming that the appropriate material has been chosen. Yes during the washing process a certain amount is not exceeded temperature for the filling material 18, this material of padding 18 may remain in the corresponding bag 10 and wash with her. In the case of filling polyester material, this limit temperature is approximately 45º, which is why general is sufficient for hygienically appropriate cleaning and not risky Only the water chamber 24 must be removed from the bag 12 before carrying out a washing process. Since the water chamber material 24, as well as that of the case of existing protection if necessary or from the safety case, is a waterproof material, the danger of dirt to the water chamber 24 is considerably smaller than for the common case 8 and / or the anti-allergic cover 4, so that if necessary it is enough a simple cleaning with a damp cloth, using if a cleaning product or disinfectant is necessary.

The filling amount of both the material of padding 18 in bag 10 like water chamber 24 in bag 12 can be regulated or changed as desired, to offer a optimal adaptation to each circumstance (sleep habits, medical indications, etc.)
