Description
FIELD

The invention generally relates to the filed of bedding and, more particularly, embodiments of the present invention relate to a mattress.

BACKGROUND

Mattresses are known which have a monolithic core (DE 814 927 B or EP 26156) which is formed with one zone or several zones. Mattresses are known which have a core which consists of several firmly attached bolster elements (DE 89 11 019 U1). Mattresses are also known which have bolster elements connected to each other (DE 298 15 524 U1).

One-piece mattresses are known whose core are furnished with a rigidified edge area (DE 10 2006 001 024 A1 and EP 1757209 A1) which are, however connected to the core, forming the resting area, in a form locking manner and, thus, form a monolithic unit.

This construction has the disadvantage that the edge area cannot be individually adjusted or subsequently changed separately from core and vice-versa.

BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTION

In one embodiment of the present invention, a mattress is provided comprising at least one core and an edge area. The at least one core forming a resting area. The edge area is connected in a non-form locked manner with the resting area of the at least one core. The edge area comprises at least one bolster element and extending along at least the longitudinal axis of the mattress.

In one embodiment, the edge area extends along the longitudinal and lateral axes of the mattress.

In another embodiment, the edge area forms a perimeter around the resting area of the at least one core along the longitudinal and lateral axes. The edge area comprises a plurality of bolster elements in a form locking connection between each other, wherein the at least one core is not connected to the edge area in a form locking manner.

In another embodiment, the at least one bolster element forming the edge area is inserted loosely into the outer cover of the mattress.

In another embodiment, the core comprises a border defining pockets along at least one of the longitudinal and lateral axes of the core, and wherein the at least one bolster elements of the edge area are mounted in the pockets.

In another embodiment, the pockets comprise zip fasteners and wherein the bolster elements of the edge area are accessible through the zip fasteners.

In another embodiment, the at least one bolster elements of the edge area in their dimensions perpendicular to the longitudinal or lateral axes have a thickness of at least 1 cm.

In another embodiment, the mattress further comprises at least one of a lower bolster plate and an upper bolster plate, wherein each of the at least one of the lower bolster plate and the upper bolster plate extends over the core and the edge areas on a corresponding side of the mattress. The least one of the lower bolster plate and the upper bolster plate not being connected in a form locking manner with either the core or the edge area.

In yet another embodiment, the edge area is connected to at least one lower bolster plates in at least one of the longitudinal or lateral directions in a form locking manner, and wherein the edge area is covered by an upper bolster plate and is not connected to the upper bolster plate in a form locking manner.

In still another embodiment, at least a portion of the bolster elements of the edge area and at least a portion of the core are covered by an outer cover.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

Embodiment examples of the invention are described on the basis of FIG. 1 to FIG. 7. Shown are:

FIG. 1: Edge area 1 stretching along the longitudinal direction in a non-form locking manner with the monolithic core area 2.

FIG. 2: Edge areas 1 and 3 stretching along the longitudinal and lateral axes with core resting area 1 b, consisting of individual elements, in a non form locking manner.

FIG. 3: Perimeter 4 formed around the resting area of the core 2 by edge areas 1 stretched along the longitudinal axis and the lateral axis. The edge areas being interconnected with each other in a form locking manner.

FIG. 4: Edge area bolster 5 in chamber 6 formed with border 7.

FIG. 5: Edge area bolsters 8 stretching along the longitudinal axis of the edge area which are connected to one or more lower bolster plates in a form locking manner.

FIG. 6: Edge area bolsters 9 stretching along the longitudinal and lateral axes of the edge area which are connected to one or more lower bolster plates in a form locking manner.

FIG. 7: Presentation analogously to FIG. 5 and FIG. 6 with one or several upper bolster plates 10 connected in a non-form locking manner.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The solution described herein is based on the problem to create a mattress at which both the resting area of the core 2 and the edge area 1 can be adjusted and subsequently be changed separately from each other relative to rigidity, supporting force, pressure relief, resting comfort and bending stiffness. Additionally, it shall ensure, with a core 2 for the resting area connected in a non-form locking manner with an edge area 1 comprising one or several bolster elements, wherein the edge areas stretch in direction of the longitudinal axis of the mattress, the lateral axis of the mattress, or the longitudinal and lateral axes of the mattress, a more stable directional control is possible than through just an outer cover.

This problem is solved by the embodiments described herein. As illustrated in FIGS. 1-3, it is achieved through the invention that the edge area 1 and the resting area of the core 2 can be adjusted separately from each other by the fact that they are connected in a non-form locking manner and can be adjusted very individually from each other and can be changed subsequently at any time relative to rigidity, supporting force, pressure relief, resting comfort and bending stiffness.

Edge area 1 and core 2 consist of upholstery material preferably of foam, but also of other materials used as upholstery material, such as air bolster, distance knit fabrics and others.

As illustrated in FIGS. 4-5, the bolster elements 5 of the edge area 2 are loosely inserted into the mattress or stowed into pockets along the border 7 of the core 1 which forms the resting area, with or without mattress cover, the pockets being freely accessible via zip fastener and connected firmly with the border of the core 7, i.e., in a secure, but non-form locking manner, so that the elements of the core 7 and the bolster elements of the edge area can be adjusted separately.

The separate edge area 2 may stretch either in direction of the longitudinal (see FIG. 1) and the lateral axis, but also in both the longitudinal and the lateral axis (see FIG. 2). As illustrated in FIG. 3, the edge area 2 may also be formed as a type of perimeter around the resting area of the core in which the bolster elements 7 of the edge area 1 are interconnected in a form locking manner.

The edge area 1 may also, for the purpose of improved stability, be connected to an upper bolster plate(s) 10 or to lower bolster plate(s) 8 or 9 or to both. In the case of just a lower or upper bolster plate, the edge area can be connected in either a non-form locking or form locking manner. In the case of both upper and lower bolster plates, the edge area is connected to one of the plates in a non-form locking manner and to the other of the plates in either a non-form locking or form locking manner.
