Description

Bedding enlarger mattress topper

The present invention relates to the field of furniture and more specifically bedding. It finds a particularly advantageous application in the field of sleeping devices such as double beds, for example. It can also be applied to other devices such as single beds or convertible sofas.

STATE OF THE ART

There are several types of sleeping device that use mattress toppers. These are additional mattresses intended to be placed on an existing mattress and provide additional comfort. Different technologies are used for mattress toppers. Mattress toppers can be used to relieve back pain, improve comfort and optimize the quality of sleep.

In the field of bedding equipment, there are many types of mattress toppers with different sizes that can be adapted to the standardized dimensions of commercial mattresses. Take the example of a classic mattress, the most common bedding in France, the 190 cm by 140 cm, it will be necessary to associate a compatible mattress topper of 190 cm by 140 cm.

In parallel with these systems, it was found, in a study, that the quality of sleep was partly dependent on the space on which a person sleeps. The more the sleeping device offers a large surface, the more the quality of sleep is improved, in particular by increasing the duration of deep sleep, the most restorative level of sleep for the body. Therefore, the length and width of a mattress are determining characteristics that indirectly influence the health status of people.

Whenever you want to increase the surface of a mattress, you opt for a larger model, compatible with a new bed base and a new mattress topper. However, there are extendable bed bases that can be extended in length or width in order to be able to position a larger mattress / mattress topper there. However, these solutions have many drawbacks, such as having to replace the mattress while it is still usable, which generally requires costs as well as a large storage space.

An object of the present invention is therefore to propose a solution which makes it possible to eliminate or limit at least one of the aforementioned drawbacks.

An object of the present invention is therefore to propose a technical solution which makes it possible, at lower cost, to enlarge the surface of a coating device.

The other objects, features and advantages of the present invention will become apparent from a review of the following description and the accompanying drawings. It is understood that other benefits may be incorporated.

SUMMARY

• une surface supérieure plane présentant une longueur l1 et une largeur L1 avec la direction de la longueur l1 perpendiculaire à la direction de la largeur L1,
• une surface inférieure parallèle à la surface supérieure, une surface périphérique externe raccordant la surface supérieure à la surface inférieure,
  le système comprend au moins un rebord de maintien, le surmatelas étant apte à coopérer avec le rebord de maintien, le rebord de maintien faisant saillie depuis la surface inférieure de sorte à présenter une surface périphérique interne configurée pour servir d’arrêt latéral au surmatelas, relativement à un matelas sur lequel le surmatelas est apte à être posé, selon au moins une direction parallèle au plan défini par la surface supérieure.

To achieve this objective, according to one embodiment, a system is provided comprising a mattress topper itself comprising:

• a flat upper surface having a length l1 and a width L1 with the direction of the length l1 perpendicular to the direction of the width L1,
• a bottom surface parallel to the top surface, an outer peripheral surface connecting the top surface to the bottom surface,
  the system comprises at least one retaining rim, the overlay being capable of cooperating with the retaining rim, the retaining rim protruding from the lower surface so as to present an internal peripheral surface configured to serve as a lateral stop for the overlay, relative to a mattress on which the mattress topper is able to be placed, in at least one direction parallel to the plane defined by the upper surface.

Without the present invention it would be necessary at least to change the bed base and the mattress.

Thus, the present invention makes it possible to limit costs by saving one or two new bed base(s) and a new mattress, because it adapts advantageously to all types of mattresses of standard or No.

Therefore, the present invention makes it possible to transform a smaller sleeping device into a larger sleeping device without having to replace existing elements but only by adding a new element.

The present invention therefore preferably makes it possible to optimize comfort and to propose a technical solution making it possible, at a lower cost, to enlarge the surface of a sleeping device.

The cooperation between the mattress topper and the rim can comprise an assembly or even a one-piece production of these two parts.

• un matelas ayant une face supérieure et une face inférieure parallèle à la face supérieure, raccordé par une paroi de flanc, la face supérieure présentant une longueur l3 et une largeur L3, et la direction de la longueur l3 est perpendiculaire à la direction de la largeur L3,
• le système configuré pour être posé sur le matelas.

According to one embodiment, the invention comprises a bedding device comprising:

• a mattress having an upper face and a lower face parallel to the upper face, connected by a sidewall, the upper face having a length l3 and a width L3, and the direction of the length l3 is perpendicular to the direction of the width L3,
• the system configured to sit on the mattress.

Thus, the bedding device is intended for at least one sleeper and has a thickness that is advantageously greater than that of a device which would comprise only a single mattress and preferentially improves the support of the sleeper.

Optionally, the bedding device may additionally have at least one of the following characteristics which may be taken separately or in combination:

According to one example, the bedding device according to the present invention comprises a bed base and preferably a headboard.

According to a particular embodiment, the bedding device is integrated within a convertible piece of furniture.

Another aspect is a method of mounting the system to a mattress.

DETAILED DESCRIPTION

Before starting a detailed review of embodiments of the invention, optional characteristics are set out below which may possibly be used in combination or alternatively:

According to one example, the at least one retaining rim is integral with the mattress topper. This makes it possible to limit the number of elements, in fact it responds to the problem of reducing costs by overcoming a pre-existing mattress with a single piece, namely a mattress topper.

According to one example, the at least one retaining rim is made hollow in a layer of foam of the mattress topper. This allows the production of a one-piece part, in fact it responds to the problem of optimizing the manufacturing process of the system.

According to one example, the retaining rim and the mattress topper form a monolithic part.

According to one example, the system distinctly comprises at least two holding flanges respectively forming the internal peripheral surface and a second internal peripheral surface parallel or perpendicular to each other and configured so as to serve as lateral stops for the mattress topper.

This makes it possible to advantageously optimize the placement of the mattress topper and improve its support. Indeed, the system is preferably placed in position using at least two retaining flanges.

According to one example, the at least one retaining rim comprises at least three retaining rims capable of serving as lateral stops on several sides of the mattress topper, preferably on three separate sides.

This makes it possible to advantageously optimize the placement of the mattress topper and improve its support. In addition, the at least three edges can considerably reinforce the rigidity of the system.

According to one example, the mattress topper comprises a notch configured so as to create a zone of weakness allowing the deformation of the mattress topper, preferably when it is folded for transport and/or for storage, then a return to its initial state when he is in position.

Indeed, without a notch, the system is advantageously rigid and cannot easily deform.

According to one example, the system of the present invention comprises a reinforcement capable of cooperating with the retaining rim so as to stiffen at least a portion at the edge of the mattress topper.

This preferentially makes it possible to limit the bending of the edges of the system. In fact, if a person leans or sits on an edge of the system, it must preferably be able to withstand the effort undergone without causing the edges of the mattress to bend.

According to one example, the area of the upper face is substantially equal to the area of the lower surface.

According to one example, the width L1 of the upper surface is greater than the width L3, preferably so that L1/L3>1.1.

According to one example, the mattress topper comprises a first material and the mattress comprises a second material such that the density of the first material is lower than the density of the second material.

This allows a more rigid support at the base of the system and a better comfort of use at the level of the upper surface. Preferably, the upper portion of the mattress topper is softer than the lower, more rigid portion.

According to one example, the first material has a heterogeneous density and in a direction oriented from the lower surface to the upper surface, the density of the first material has a gradual decreasing evolution.

This allows, for example, a more controlled distribution of the material within the system and consequently better control of the functional characteristics of the present invention, namely that the edges of the mattress topper do not flex while maintaining comfort.

According to one example, the device comprises a bed base, a headboard, a mattress and the system according to the present invention.

It is specified that in the context of the present invention, the word “plane” associated with a surface is understood as a surface which can be associated with a plane. Roughness will not be taken into account. It can be considered as flat, the upper surface and the lower surface of the mattress topper. Similarly, the upper face and the lower face of the mattress may be considered as flat.

During the description, it will be appropriate to call "footboard" the area opposite the "headboard".

It is specified that, in the context of the present invention, the terms “on”, “overcomes”, “covers”, “covers” and their equivalents do not necessarily mean “in contact with”. Thus, for example, the mattress topper is on the mattress does not necessarily mean that the two entities are always directly in contact with each other, but means that the mattress topper at least substantially covers the mattress by being either directly in contact with it, or by being separated from it by at least one other element such as for example a sheet or a sheet.

In the following description, unless otherwise specified, when referring to absolute position qualifiers, such as "front", "rear", "up", "down", "left", "right" , etc., or relative, such as the terms "above", "below", "upper", "lower", etc., or to qualifiers of orientation, such as the terms "horizontal", "vertical", "lateral", etc., reference is made to the orientation of the corresponding figures, it being understood that, in practice, the devices and assemblies described may be oriented differently.

Similarly, when it is indicated that an element is located in line with another element, this means that these two elements are located on the same line perpendicular to the main plane in which one face of a mattress or mattress mainly extends. a mattress topper, that is to say on the same line oriented vertically in the figures.

In the figures, the thickness is taken along the vertical in the zones which extend mainly horizontally.

The term “substantially” means “within 10%, preferably within 5%”.

• positionnées à distances l’une de l’autre, et/ou
• mobiles l’une par rapport à l’autre et/ou
• solidaires l’une de l’autre en étant fixées par des éléments rapportés, cette fixation étant démontable ou non.

In the present patent application, when it is indicated that two parts are distinct, this means that these parts are separate. They are :

• positioned at a distance from each other, and/or
• movable relative to each other and/or
• secured to one another by being fixed by inserts, this fixing being removable or not.

A unitary one-piece part cannot therefore be made up of two separate parts.

In the present patent application, the term "united" used to qualify the connection between two parts means that the two parts are linked/fixed with respect to each other, according to all the degrees of freedom, except if is explicitly specified differently. For example, if it is indicated that the overlay and the retaining rim are integral in translation in a direction Oz, this means that the parts can be movable relative to each other, except in the direction Oz. In other words, if we move a piece in the Oz direction, the other piece performs the same movement.

We will also use a marker whose longitudinal or rear/front direction corresponds to the Oz axis, the transverse or right/left direction corresponds to the Y axis and the vertical or bottom/top direction corresponds to the Z axis.

MAIN EMBODIMENT

FIGURES 1A and 1B

In Figures 1A and 1B, there is shown an advantageous system of the present invention comprising a mattress topper 1 and a retaining rim 13 extending along three sides of the mattress topper 1. The mattress topper 1 comprising an upper surface 11 is flat and has a length l1 and a width L1 so that the length l1 is oriented along the axis Ox and the width L1 along the orthogonal axis Oy.

The mattress topper 1 comprises a lower surface 12 parallel to the upper surface 11. The outer peripheral surface 14 effecting a connection between the upper surface 11 and the lower surface 12.

As illustrated in FIGS. 1A and 1B, the system comprises a retaining rim 13 projecting from the lower surface 12. The retaining rim 13 extends from the lower surface 12 in the direction Oz so as to present an internal peripheral surface 16 configured to serve as a side stop relative to a mattress 3 not shown in Figures 1A and 1B.

According to one embodiment, the lateral stop is made by direct contact or by means of an element interposed between the internal peripheral surface 16 and the mattress 3. The contact is made in at least one direction parallel to the plane defined by the upper surface 11.

STRUCTURAL CHARACTERISTICS

According to one embodiment, the retaining flange 13 and the mattress topper 1 are made of the same foam.

According to another embodiment, an open cavity is hollowed out in the overlay 1 in order to form the retaining rim 13. Advantageously the overlay 1 and the retaining rim 13 form a single piece. The mattress topper 1 and the retaining rim 13 are thus integral in translation along a direction Oz.

According to another embodiment, the system comprises a notch 19 able to generate a zone of weakness. Advantageously, this zone of weakness allows the deformation in bending of the system around an axis parallel to the direction Ox. The notch 19 is preferably centered on a retaining rim 13 preferably at the level of the footboard, and perpendicular to the direction Ox. According to one example, in the case where the system comprises at least three retaining edges 13, then the system will be more rigid and it will be difficult to position it on the mattress 3 knowing that there is only little play since the lower surface 12 is substantially equal to upper face 31. Possibly, the play can be negative so that a static pressure applies the edge to the mattress.

According to one embodiment, the notch 19 is preferably centered on a retaining rim 13 perpendicular to the direction Oy so as to allow the system to be deformed in the same way in a direction parallel to the axis Oy.

Preferably the notch 19 preferentially facilitates the folding of the mattress topper 1, preferably to optimize a transport and/or storage step.

According to one embodiment, the system does not include a notch 19.

According to another embodiment, the system comprises a first material. Preferably, the mattress topper 1 and the retaining flange 13 are made of the same material. Preferably the first material is a foam. According to one embodiment, the first material is feather, down, gel or natural or synthetic fibers. It can be, for example, a high resilience foam, a high density foam or a shape memory foam.

According to another embodiment, the mattress topper 1 is made of a first material and the retaining rim 13 is made of a second material and the density of the second material being greater than the density of the first material.

According to a particular embodiment, the system comprises a set of material whose density varies in decreasing manner along the Oz axis oriented in the positive direction. Advantageously, the density of material of the retaining rim 13 at the level of the peripheral surface 18 is higher and the density of material of the overlay 1 at the level of the upper surface 11 is lower. Between the peripheral surface 18 and the upper surface 11, the density decreases progressively, continuously or else by strata of materials. These strata are preferably layers of foams or other materials.

FIGURES 2A and 2B

In Figures 2A and 2B, is illustrated a step of assembling the system with the mattress 3 within the bedding device.

According to one example, the system of the present invention is able to be integrated within a bedding device comprising a mattress 3 so that the system is stacked on the mattress 3.

As shown in , the mattress 3 is advantageously integrated into a bedding device comprising a bed base 2 and a headboard 4. The mattress 3 has an upper face 31 and a lower face parallel to the upper face 31. The two faces are connected by a wall flank 32. The upper face 31 thus has a length l3 in the direction Ox and a width L3 in the orthogonal direction Oy.

According to one embodiment, the side wall 32 is exposed in order to be able to cooperate with the at least one retaining flange 13 of the mattress topper 1. Preferably, the area of the lower surface 12 is delimited by the retaining flanges 13 and is substantially equal to the area of the upper face 31, the aspect ratios being otherwise preferably identical. This preferably allows a tailor-made coupling of the mattress topper 1 on the mattress 3. Thus the mattress topper 1 is located in line with the mattress 3.

According to one example, the mattress topper 1 is advantageously configured to be able to cooperate with the mattress 3 so that the upper face 31 is in contact with the lower surface 12 and that, simultaneously, the internal peripheral surface 16 is in contact with the wall. sidewall 32. Preferably, the internal peripheral surface 16 also allows a transfer of the vertical stresses that the sidewall wall 32 may undergo.

According to one embodiment, the mattress topper 1 comprises at least two retaining edges 13 in order to optimize the holding in position of the mattress topper 1 on the mattress 3. Advantageously, the mattress topper 1 comprises exactly two retaining edges 13 having respectively and distinctly a inner peripheral surface 16 and a second inner peripheral surface 16'. Preferably, the internal peripheral surface 16 is parallel to the second internal peripheral surface 16' and the two retaining flanges 13 extend in the direction of the length l1 and are distributed symmetrically on each side of the mattress topper 1. Preferably, the two retaining flanges 13 are of the same size.

According to one embodiment, the mattress topper 1 comprises at least three retaining edges 13 so as to accentuate its rigidity while optimizing the retention in position of the mattress topper 1 on the mattress 3. Preferably the first two retaining edges 13 are configured as in the previous embodiment, namely extending in the direction of the length l1 and distributed symmetrically on each side of the mattress topper 1, while the third retaining flange 13 is configured to cooperate with the side wall portion 32 located at the foot of the bed.

According to a preferred mode, the three retaining flanges 13 are contiguous and, in the direction carried by the axis Oz, they are of the same size so as to form a peripheral surface 18. This allows, as illustrated in , a regularity of shape and an optimized positioning. Preferably, the system does not include a retaining rim 13 on the side of the headboard 4.

FIGURES 3A and 3B

According to one embodiment and with regard to the example illustrated in , the retaining flange 13 has a regular thickness e13. The thickness e13 corresponds to the distance between the lower surface 12 and the peripheral surface 18. In the case where the retaining rim 13 has an irregular thickness, the thickness e13 should be considered as the thickness in the direction Oz of the larger portion of the retaining flange 13.

According to another embodiment, the thickness e ₁₃ is less than a visible portion of the sidewall 32 along the axis Oz. This makes it possible to ensure the contact of the surface 12 on the upper face 31.

As shown in and according to one embodiment, the system comprises a reinforcing element 5 capable of cooperating with the retaining flange 13, preferably capable of cooperating simultaneously with the peripheral surface 18 and the internal peripheral surface 16 so as to mechanically reinforce the flange holding 13 facing the mechanical stresses that can be exerted in the direction Oz oriented towards the ground.

Preferably, the system comprises several reinforcing elements 5, preferably identical, and for example distributed in a symmetrical and homogeneous manner along the retaining rim 13. Preferably, the reinforcing element 5 may be made of metal or of a material more rigid than the retaining flange 13, for example in the shape of a square and according to an embodiment resulting from a sheet metal manufacturing process comprising cutting and bending.

As illustrated in Figures 4A to 4C, the system may include a specific number of retaining flanges, exactly two retaining flanges 13 as shown in and preferably on each side of the mattress topper 1, lengthwise. Preferably and as shown in , the system comprises three retaining flanges 13 distributed over three separate sides so as to leave one side free, preferably in the direction of the width and preferably on the side of the headboard 4. According to one embodiment, the system comprises at least three retaining edges 13 and preferably exactly four separate retaining edges 13 preferably distributed symmetrically in pairs, along a median plane of the mattress topper 1, and preferably without notch 19.
