Abstract

The invention relates to a mattress pad for the top of the mattress of a Liegestatt in the form of an outer shell and enclosed by the outer shell filled with water cavity, wherein the outer shell has a communicating with the cavity inlet valve with a tightly sealable water filling. DOLLAR A To improve a mattress pad so that it has an improved utility value, it is designed so that the mattress pad is associated with an electrical connection and an associated heater for the filled water and that the cavity is generally free of damping inserts such as fabrics, nonwovens or the like and that the thickness of the mattress pad is only so low that, despite the lack of damping inserts when lying creates the comfort of a comforted water mattress.

Description

The The present invention relates to a mattress pad according to the preamble of the main claim.

Essential for the Invention is the basic idea that the mattress pad a Has water chamber. The mattress pad should be on top an existing mattress, couch, hammock or one other underground.

For this the mattress cover consists of an outer shell, which can be filled with water cavity offers.

Of the Cavity can over an inlet valve filled with water so that under Using a mattress located below the mattress topper or similar with the comfort of a water mattress or a waterbed Comparable lying comfort arises.

Such water-fillable mattress pad is from the DE 298 15 821 U1 known.

The Water in the cavity is introduced via an incorporated nonwoven fabric or similar in his flow, Schwapp and wave movements so calmed that for the user the comfort of a calmed water mattress arises.

A Such mattress pad is, however, despite their in comparison to a water mattress of small volume practically only locally usable.

It is therefore an object of the present invention, the known mattress pad educate so that they has an improved utility value.

These Task solves the invention with the features of the main claim.

Out The invention has the advantage that the mattress pad as a hand luggage easily transportable is and thus local independently can be used by anyone.

Especially It also serves the purpose of a person traveling while traveling Feeling familiar from home to give the individually comfortable sleeping place.

This Advantage is achieved in that on the one hand the damping inserts be omitted, so that inside the cavity no water-absorbent materials which could unnecessarily increase the weight of the emptied mattress overlay.

To the Transport of the mattress pad according to the invention therefore only needs that located inside the cavity Water to be let out, so that only the pure Material weight of the mattress pad is to transport.

Furthermore However, the invention has also recognized that between the water-filled mattress pad and an upper limited thickness thereof a combinatorial Effect on the one hand, the comfort of a usual Mattress pad generated while on the other hand, a limitation of thickness damping functions of the back and forth flowing Water causes the comfort of a soothing water mattress cause.

there the thickness of the mattress pad is primarily based on the criterion of light weight To be sized during transport. Also thicknesses up to about 7 cm are included in the invention, as long as the cavity is not filled with water but the flow movements soothing squeezing effect can be harnessed.

this includes is to be understood that to Calming the flow movements conventionally in a water mattress and also in that of the aforementioned Utility model known mattress cover fabrics, fleeces or the like are housed.

These activities serve the purpose, the flowing one Water a variety of bottlenecks, throttles or the like to oppose, so that no undamped Sloshing movements can occur.

Here the invention goes another way.

By a correspondingly low training of the mattress pad advantageously together with a low degree of filling arise bottlenecks especially in the lying area of the dormant person between the top and bottom of the outer shell, through which the water must be squeezed through in the manner of chokes. It leads the Throttling effect to the desired Damping properties, without that specially introduced any calming materials in the cavity have to be.

In this case, the throttle points change for et Waige flow movements of the water due to the body movements of the person at rest, while at the same time the mattress located below the mattress or the like even then gives a calm soft Liegestatt when the top and bottom of the outer shell of the mattress overlay touch tightly for the moment.

This is e.g. then the case when the dormant person with the knee, the Elbows, pelvic bones or the like on the mattress overlay, so that water in the cavity completely squeezed out at this point becomes.

It is therefore essential for the invention, taking into account a perceived as comfortable degree of filling the thickness of To limit mattress overlay so that despite missing damping inserts a damping effect entry. The damping effect however, it only occurs when a person is lying on the mattress topper rest, because only then to steam the flow movements necessary bottlenecks are formed in the cavity.

These However, bottlenecks are not fixed in time and place. she vary constantly. For example, if the person turns from one side to the other, is indeed the previously in the unused area of the mattress pad located water expelled in the cavity. At the same time though wander the while the turning generated by the person at rest bottlenecks in the cavity in the opposite direction, so that the desired throttle effect / damping effect arises.

In addition is but also important, the water in the cavity as needed to heat up to comfort temperature.

For this The mattress pad is an electrical outlet and one associated with associated heater, so that in the Cavity water at any time to the comfort temperature can be brought. For this purpose, the use of a thermostatic Loop proposed.

There However, these are only comparatively small amounts of water does not require any elaborate thermal insulation measures. Outside the use of the mattress pad during the day the heater by means of timer also be switched off.

To Use can be simply drain the water in the cavity and the mattress pad can be simply rolled up / folded.

The Lack of any damping inserts required therefore only after a small storage volume. According to the invention, the Mattress topper like a handbag / briefcase simple and essentially be transported without effort.

The Thickness of the mattress pad should be between about 0.5 cm and 3.5 cm, preferably up to about 7 cm.

Based to the usual Sizes of such mattress pads with a base area between 90 cm to 100 cm × 190 cm to 200 cm, this corresponds to a void volume between about 10 l and about 70 l up to a maximum of 140 l.

Becomes the inlet valve at the top or bottom of the mattress overlay attached, the possibility arises a particularly simple emptying of the cavity.

For this The mattress overlay, filled with water, will weigh about 30 kg to 60 kg is, with its end, where the inlet valve sits, in the bathtub hanged and subsequently the inlet valve is opened. For larger weights let yourself the emptying e.g. above an accessory hose with corresponding connection also just perform.

There the inlet valve for easy emptying of the cavity as well Drain valve is used, can roll over a the mattress overlay in the longitudinal direction or by folding out completely the water in the interior and the empty mattress pad is handy to transport Form available.

Conveniently, is the underside of the mattress pad over the usual fabric materials used for mattresses Non-slip trained, unless slipped by the water weight impossible is.

This can be realized on the one hand by a non-slip slipcover, which surrounds the mattress pad.

Furthermore the slipcover can be designed in the manner of a fitted sheet and the mattress topper along with the one underneath Mattress or similar include the Liegestatt. But it is also a slipcover conceivable which only covers the mattress pad.

In addition, a number of double-sided adhesive tapes or similar fixations such as hook-and-loop fasteners can sit on the underside of the mattress pad, the components of which are simply located on the upper side of the mattress pad below glued mattress.

From Particular advantage is a development of the invention, in which on the mattress pad a handle for carrying the folded mattress pad is provided.

in the Following, the invention will be explained in more detail with reference to embodiments.

It demonstrate:

1 A first embodiment of the invention in the position of use,

2 an embodiment of the invention, in part, merged,

3 a water filling hose,

4 an electrical connection,

5 Phantom view of the invention in top view,

6 a cross section of the view according to 5 .

7 a longitudinal section of the view according to 5 , and

8th a further embodiment of the invention.

Provided unless otherwise stated below, the following description applies always for all figures.

The figures show a mattress pad 1 , The mattress pad 1 serves the purpose on an already existing mattress 2 be placed by conventional design with spring core, foam core or the like.

If necessary, the conventional mattress can 2 on a bedstead 3 are located.

This Although the normal case, from which the invention proceeds, but should no limitation of Mean invention.

Just as well can the conventional mattress 2 on the floor of a bedroom.

The mattress pad 1 is placed on the top of an existing mattress and suitably non-slip connected to this.

In principle, the mattress overlay is a water mattress of only small thickness 13 ,

For this purpose, the mattress pad 1 a waterproof outer shell 6 on which a cavity 7 encloses.

The cavity 7 is filled with water.

For this purpose owns the outer shell 6 one with the cavity 7 communicating inlet valve 5 , which has a filling hose 17 directly connected to an in-house water connection.

These It is an inlet with screw, the filling can also be with a watering can cause.

At the inlet valve 5 For example, a water-tight closable water filling connection is realized via a valve body with associated valve seat or a screw cap, so that the mattress overlay practically at every location via the filling hose 17 or a watering can is easy to fill.

In addition, there is also an electrical connection 4 provided, for example via a power supply 18 can be connected to the public power grid.

The electrical connection 4 is with one in the cavity 7 However, the mattress act expediently outside the cavity 7 arranged heating device 10 connected, so that in the cavity 7 filled water is constantly heated to a comfortable temperature corresponding temperature. The heater can - operated with mains voltage - advantageously sit in a separate pocket on the underside of the mattress.

As 8th If necessary, the mattress pad is replaced by a tub-like floor liner 20 surrounded so that the heater 10 also between mattress pad and floor liner 20 or in the absence of a liner 20 can also sit between the mattress topper and the mattress.

For the special design of inlet valve 5 and permanent heater 10 However, reference is made to the prior art.

It is essential, however, that the cavity 7 Generally free of damping inserts, with the help of so-called calmed water mattresses flow and sloshing movements of the filled water should then be damped when the person resting on the mattress pad moves.

Accordingly, located within the cavity 7 if necessary form retaining webs, with the aid of which the upper and lower web of the outer shell 6 be kept at a maximum possible distance to a local inflation of the mattress pad 1 to prevent.

By using a permanent liner 20 However, the Formhaltestege can be omitted. The upright liner can be made of a material comparable to the material of the outer shell, eg vinyl, and has a relatively firm edge, so that it can possibly also perform the function of a water collecting tray.

However, to the essential property of the mattress pad according to the invention for virtually residue-free emptying of the cavity 7 To take into account are the Formhaltestege 8th with breakthroughs 9 provided, the breakdown surface allows virtually no damping function.

At least but are the breakthrough areas like that large, that one filled with water Mattress pad within the shortest possible time Time virtually residue-free emptied Can be used to make the emptied mattress pad kind of an easy portable travel hand luggage to be able to take.

In order nevertheless to obtain the comfort feeling of a calmed water mattress with the mattress pad according to the invention, the thickness is 13 the mattress cover only so small that the upper and lower sheets of the outer shell have so far approximated each other under the weight of a person resting on the nature of a variety of individual throttle points that unimpeded back and forth flowing of the water in the cavity is prevented by the throttle bodies ,

The Throttling points therefore work for the flowing Water as individual valves with high flow resistance, so that only from the low altitude the mattress topper of only a few centimeters a the comfort feeling increasing calmness in the water flow arises.

there offers the small thickness about it In addition, the very significant advantage of a low weight the water filled Mattress topper, so this practically on every bedstead together with one underneath anyway located mattress can be placed.

It Therefore, thanks to the present invention requires no static verification of Ceiling construction, because the weight of the complete with water filled Mattress topper moves in the range up to only about 150 kg.

The Invention is thus the successful integration of a virtually everywhere usable Mattress topper that gives the comfort of a soothing water mattress offers and in particular with regard to the existing thermostatic regulated continuous heating also the appropriate comfort temperature, at the same time the significant disadvantage of the high weight of so-called calmed water mattresses can not be accepted.

It should be the cavity 7 a volume between about 10 l up to 70 l, a maximum of about 140 l enclose.

This corresponds to a thickness 13 at a common footprint of 90 cm to 100 cm × 190 cm to 200 cm, which is between about 0.5 cm to 3.5 cm, a maximum of about 7 cm.

This small thickness of the mattress pad 1 offers the advantage of easy handling without having to forego suspension comfort, because this is ensured by the mattress located below the mattress.

Conveniently, the inlet valve is located at the head end or at the foot end of the Mattress topper.

In this development, the inlet valve 5 Also provided as a drain valve, for example, by the valve body can be displaced by simple lateral pressure from the outside to the inlet valve in the opening direction, the mattress overlay can be as it were empty in a train in the bathtub and can then be rolled up simply as a travel luggage.

Dimensions of the rolled up mattress pad according to 2 therefore correspond to the width 12 (= Length of baggage) and a roll thickness of up to 25 cm, depending on how big the length 11 the rolled out mattress pad 1 is and the thickness of the individual roll layers with completely empty cavity 7 , But there are also foldable mattress pads into consideration, the folded about the dimensions have 50 cm × 50 cm × 2 cm.

In particular 2 shows, at one of the marginal edges a carrying handle 15 be provided so that the rolled mattress pad 1 that have packing straps 16 how a piece of luggage remains rolled up, easily and unobtrusively transportable.

In addition, it is proposed the bottom of the mattress pad 1 compared to conventional fabric materials, as they are used on mattresses, non-slip form. However, this does not seem necessary.

This can e.g. done by spiky or velcro-like slip brakes.

Furthermore The mattress pad can also be made of a non-slip slipcover be enveloped.

Depending on the application, the protective cover may also be designed in the manner of a fitted sheet, so that the laid on a conventional mattress mattress pad 1 is covered by the slipcover together with the mattress. A slipcover, which includes only the mattress pad, is conceivable and also a box cover with zipper.

On the other hand, it is also conceivable, on the underside of the mattress pad 1 To provide mounting surfaces on which conventional double-sided adhesive tape - preferably renewable - can be attached.

This double sided tape 14 then adheres on the one hand to the mounting surface on the underside of the mattress pad and on the other hand on top of the mattress, but can be solved again at any time if required.

Essential is so far that the Mattress topper together with the mattress underneath provides a uniform Liegestatt whose individual components relative to each other no horizontal relative movement to each other To run should.

Of the particular advantage of the invention is the fact that due the small thickness of the mattress overlay and the resulting low volume content even instead of egg ner heater a cooling device with low Power consumption possible is, e.g. a Peltier element.
