Description
FIELD
[0001] The invention generally relates to the filed of bedding and,
more particularly, embodiments of the present invention relate to a
mattress.
BACKGROUND
[0002] 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).
[0003] 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.
[0004] 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
[0005] 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.
[0006] In one embodiment, the edge area extends along the
longitudinal and lateral axes of the mattress.
[0007] 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.
[0008] In another embodiment, the at least one bolster element
forming the edge area is inserted loosely into the outer cover of
the mattress.
[0009] 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.
[0010] In another embodiment, the pockets comprise zip fasteners
and wherein the bolster elements of the edge area are accessible
through the zip fasteners.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
