Description

TWO-PARTS CUSTOMIZABLE MATTRESS
FIELD OF THE INVENTION
The present invention relates generally to the use of magnetic fasteners for holding together, fitting, adjusting or fastening two layers of a mattress. Also a method for automatically fitting a top layer of a mattress on a bottom layer of the mattress is disclosed.
BACKGROUND TO THE INVENTION
A mattress is an important purchase and is intended to provide the user with a sleeping surface that can last for years. Though, each individual's physique and personal preferences may change with time and may also vary in each season, and users are then forced to replace their entire mattress to meet their changing needs. Conventional bedding mattresses also failed to satisfy each user because no two individuals share the same preferences in the comfort and support of their mattress. In addition, during normal use, a mattress, and in particular the top cover of the mattress is subject to wear and tear and to exposure of liquids that may accidentally be spilled on the mattress.
Manufacturers have attempted to combat this problem by creating customizable hybrid mattresses, where each mattress includes two half mattresses, and where the top layer can be changed according to the individual's preferences, such as for example defined in WO200018275 and US201 1094039. These modular mattress systems have been developed to provide individualized mattress systems that allow the user to continually customize or replace a portion of the mattress. As a result, multiple modifications and variations can be made.
An important disadvantage of these hybrid mattress systems is that the top layer needs to be placed in the right position on the bottom layer. In particular, the surface area of a two-persons mattress is large and correct placing of the top layer of said mattress on the bottom layer can be time consuming and difficult. In addition, the top layer needs to be firmly fixed to the bottom layer to prevent shifting of the top layer during the night when a sleeping person is still making a considerable number of movements. Currently used fastener systems to secure a top layer on a bottom layer of a mattress include zippers, or hook-loop systems such as Velcro™ or buttons, but the use of these systems is time consuming and careful positioning of the top layer into the right position on the bottom layer is required. Secure systems using magnetic fasteners in a mattress setting are also available, as described in DE202008000249 U1 , though without any anti-magnetic protection, thereby limiting their use in medical applications in which protection from strong magnetic fields is essential.
It is accordingly an object of the present invention to provide the use of a fastening system that allows the automatic fitting of a top layer of a mattress in the right position on a bottom layer of said mattress and that can be used in medical applications as well.
SUMMARY OF THE INVENTION
The present invention is directed to the use of a magnetic fastener in a mattress setting for holding together, fitting or fastening a top layer (1 ) and a bottom layer (2) of a mattress, said magnetic fastener comprising a first part (3) and a second part (4) used for holding together, adjusting, fitting or fastening two layers of a mattress, wherein the first part comprises at least one first sheath (5) in which at least one first magnet or ferromagnetic element is inserted, these being attached inside said first sheath (5), and a second part containing at least one second magnet or ferromagnetic element subject or submitted to the magnetic attraction of the first magnet or ferromagnetic element of the first part, and characterized in that each magnet of the fastener is associated with an anti-magnetic protection component. The use of such an anti-magnetic protection component results in an almost complete neutralization of the magnetic field on the outside of the magnetic fastener. Hence, the use of a magnetic fastener in a mattress setting as described above can also be applied in a medical setting for people carrying pacemakers or other medical devices that should be protected from strong magnetic fields. Preferably, the present invention provides the use of a magnetic fastener in a mattress setting for holding together, fitting or fastening two layers of a mattress, wherein the second magnet or ferromagnetic element is attached to the second part of the magnetic fastener.

DETAILED DESCRIPTION OF THE INVENTION
In the context of the present invention, "mattress" means a ticking filled with resilient material used alone or in combination with other products intended or promoted for sleeping upon.
The present invention is directed to the use of a magnetic fastener in a mattress setting for holding together fitting or fastening two layers of a mattress. Traditional mattresses generally comprise only one layer. A major disadvantage is that this type of one-layer mattress cannot be customized during time, whereas each individual's physique and personal preferences may change with time and may also vary in each season. To provide a solution for these disadvantages, hybrid mattress systems, such as for example described in WO200018275 and US201 1094039 have been developed in the past and are currently part of the prior-art. An important disadvantage of these systems is the mechanism by which the two layers are fixed together, such as a zipper or a hook-loop system like Velcro™. Secure systems using magnetic fasteners in a mattress setting are also available, as described in DE202008000249 U1 , though without any anti-magnetic protection, thereby limiting their use in medical applications in which protection from strong magnetic fields is essential. The present invention comprises the use of a magnetic fastener in a mattress setting for holding together, adjusting, fitting or fastening two layers of a mattress. The invention is characterized in that the magnetic fastener that is used comprises a first part and a second part used for holding together, adjusting, fitting or fastening two layers of a mattress, wherein the first part comprises at least one first sheath in which at least one first magnet or ferromagnetic element is inserted, these being attached inside said first sheath, and a second part containing at least one second magnet or ferromagnetic element subject or submitted to the magnetic attraction of the first magnet or ferromagnetic element of the first part. The magnetic fastener that is used was disclosed in WO0033328 and WO03056956 for holding together, adjusting, fitting or fastening parts of a garment, shoe, or any other accessory. Typical for the present invention is the use of a magnetic fastener in a mattress setting as detailed above, wherein each magnet of the fastener is associated with an anti-magnetic protection component. The use of such an anti-magnetic protection component results in an almost complete neutralization of the magnetic field on the outside of the magnetic fastener. Hence, the use of a magnetic fastener in a mattress setting as described above can also be applied in a medical setting for people carrying pacemakers or other medical devices that should be protected from strong magnetic fields. It is accordingly an object of the present invention to provide the use of magnetic fasteners in a mattress setting as detailed herein, and characterized in the presence of an anti-magnetic protection component, such as for example an anti-magnetic covering at one side of the magnets as shown in figures 3a-f, 3j and 3k of WO0033328.
In the context of the present invention, said magnetic fastener is used for holding together, adjusting, fitting or fastening two layers of a mattress. In a particular embodiment, the second magnet or ferromagnetic element is attached to the second part. Typical for the magnetic fastener is that it comprises two parts, wherein the first part comprises at least one first sheath in which at least one first magnet or ferromagnetic element is inserted and being attached inside said first sheath. In another embodiment, the second part of the magnetic fastener contains at least one second magnet or ferromagnetic element that is attached to the second sheath. In another particular embodiment, the first and/or second part of the magnetic fastener has at least two sheathes. In an even further embodiment, the first and second parts of the magnetic fastener have a series of magnets or ferromagnetic elements hinged together, their number being sufficient to surround the total peripheral edge portion of three of the four sides of the top and/or bottom layer of the mattress.
Typical for the present invention, is that the first part of the magnetic fastener is secured to the top layer of the mattress. This first part of the magnetic fastener is secured to the peripheral edge portion of the top layer of the mattress. Even more in particular, this first part of the magnetic fastener is secured to the peripheral edge portion of three of the four sides of top layer of the mattress. Furthermore, the second part of the magnetic fastener that is used in the present invention is secured to the bottom layer of the mattress, wherein the second part of the magnetic fastener is secured to the peripheral edge portion of the bottom layer of the mattress. In a particular embodiment, the second part of the magnetic fastener is secured to the peripheral edge portion of three of the four sides of the bottom layer of the mattress. Because the peripheral edge portions of three of the four sides of both layers are completely covered with a part of the magnetic fastener, both layers, when positioned on top of each other, are firmly fixed together and the magnetic attraction between both layers was found strong enough to keep both layers in the right position, even to the extend that the top layer cannot be shifted during the night when a sleeping person is still making a considerable number of movements. Currently used fastener systems to secure a top layer on a bottom layer of a mattress include zippers, or hook-loop systems such as Velcro™ or buttons, but the use of these systems is time consuming and the top layer still needs to be put manually in the right position on the bottom layer.
Furthermore, the present invention also comprises the use of a magnetic fastener in a mattress setting as defined in any of the embodiments described herein above, wherein the surface area of the top layer and the bottom layer of the mattress have the same size. As explained above, the magnetic fasteners are secured to the peripheral edge portion of each layer. Therefore, it is unnecessary that an overhang is created in the top layer to secure this layer on the bottom layer, as is often seen in mattress covers that are described in the prior-art such as defined in US7930779. Since both layers of the mattress that is used in the present invention have the same size, no extra fabric is needed, which reduces the production costs of said mattress.
In a further embodiment, the use of a magnetic fastener in a mattress setting for holding together, adjusting, fitting or fastening two layers of a mattress, comprises the use of magnets produced from the family of rear earths of the type Neodynium Iron Boron.
By the use of the specific magnetic fasteners in a mattress setting as described above, an autofit mechanism is created whereby the top layer automatically fits in the right position to the bottom layer. This facilitates the application of the top layer to the bottom layer of the mattress and hence facilitates and stimulates a switch between top layers. It will be apparent to those skilled in the art that various modifications and variations can be made in the customizable mattress system of the present invention. For example, top layers can be changed according to the season, with an autumn/winter and spring/summer top layer that can be applied to the same bottom layer.
