ADJUSTABLE MATTRESS STRUCTURE
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present disclosure relates to an adjustable mattress structure,
particularly an mattress structure with an adjustable-firmness mattress body
for
supporting a user's body curve by means of a distance changed between an
adjustable
positioning board inside a hollow base and a second encapsulated elastomer.
2. Descriptions of the Related Art
[0002] A spring mattress available in the market comprises pads, a spring
frame and a mattress encasement. The pads are stacked on the spring frame's
top and
bottom edges; the mattress encasement covering the pads and the spring frame
is a
package-like body with an opening. A spring mattress is developed after the
spring
frame along with the pads stacked on the spring frame's top and bottom edges
are
placed into the mattress encasement and the opening on the mattress encasement
is
seamed.
[0003] The spring frame in the above spring mattress comprises several
barrel-shaped pocket springs, each of which is a tubular body made of non-
woven
fabric and including a spring internally. As spring units, all adjacent barrel-
shaped
pocket springs which are arranged lengthwise and widthwise for tubular bodies
connected to one another are elastically compressed and deformed under stress
applied
on the spring frame upward and downward. As such, the spring frame which
matches
the body curve of a user lying down a spring mattress is elastically deformed.
iµ
I I
CA 02988177 2017-12-04
[0004] The spring frame, however, is poorly adjusted because all spring units
which refer to a user's body curve for elastic deformation perform identical
elasticity
rather than flexibly adjusted elasticity based on a user's sleeping preference
or habit at
a mattress surface. Thus, elastomers compressed inside a conventional spring
mattress
on which a user's weight is sustained do not support a user effectively.
[0005] The applicant of the present invention has submitted the China Patent
Application No.201010259987 titled "Mattress Structure" (hereunder referred as
"the
Quoted Application") on August 23, 2010, which is technically characterized
in:
comprising a fixation board fixed within the mattress body, at least a first
elastomer
being installed on the fixation board and an elastomer accommodation hole
being
configured at the bottom end of the first elastomer; a second elastomer
installed
correspondingly to the elastomer accommodation hole on the movable board below
the
fixation board, and at least one set of lifting devices installed at the
bottom of the
movable board, such that, through such lifting devices, upon moving up the
movable
board towards the fixation board, the second elastomer on the movable board
can move
up through the elastomer accommodation hole so as to increase the elastic
supportive
force of the mattress; in addition, by means of the up/down movement of the
second
elastomer, it is possible to achieve the objective of elasticity adjustment in
the mattress.
[0006] It can be appreciated that the aforementioned Quoted Application is
essentially characterized in electrical adjustments, rather than manual
adjustments,
which differs from the present application with respect to the integral
structure thereof;
accordingly, to effectively reduce total costs, the applicant alternatively
devoted

relevant research and development efforts on spring beds featuring manual
elasticity
adjustments.
[0007] To overcome the above problem, a preferable solution in the present
disclosure indicates a mattress structure is divided into several lengthwise
components
in which a distance between an adjustable positioning board and an
encapsulated
elastomer is adjusted so that a user's body curve is flexibly supported by
elasticity at
different positions on a mattress body.

inside the first encapsulated elastomer, and the bottom of the second
encapsulated
elastomer is allowed to extend beyond the bottom of the first encapsulated
elastomer;
in addition, the first encapsulated elastomer is arranged and fixed on the top
surface of
the hollow base such that the bottom of the second encapsulated elastomer
enters into
the opening on the top surface of the hollow base; and a plurality of

positioning boards, each of which penetrates via the opening on the front
surface of the
hollow base and is fixed onto the slide seat on the two sides of the interior
within the
hollow base, such that each hollow base is equipped with an adjustable
positioning
board placed under the bottom of the second encapsulated elastomer, and the

[ 0010] In an embodiment, the first encapsulated elastomer includes
at
least a spring wrapped by an encapsulation package and the second encapsulated
elastomer includes at least a spring wrapped by an encapsulation package, such
that the
tops of the first encapsulated elastomer and the second encapsulated elastomer
mutually adjoin thereby allowing the second encapsulated elastomer to suspend

interior of the hollow base and whose two ends can be respectively fixed to
the two
opposite sides of the long sides in the hollow base, such that the elastic
carrier is
situated at the topmost end inside the hollow base and above the highest slide
seat, and
the elastic carrier is applied to receive the second encapsulated elastomer so
that the
elastic carrier can catch the second encapsulated elastomer when the second
encapsulated elastomer falls thereby preventing the second encapsulated
elastomer
from directly falling onto the button surface of the hollow base and blocking
the
adjustable positioning board from completely sliding into the hollow base.
[0014] In an embodiment, a positioning slot is configured at the periphery of
the opening in the top surface of the hollow base, and the positioning slot
can be
combined and positioned to the bottom of the first encapsulated elastomer
thereby
allowing the first encapsulated elastomer to be positioned at the periphery of
the
opening in the hollow base.
[0015] In an embodiment, a clamping member is installed at the periphery of
the opening in the top surface of the hollow base, and the clamping member can
be
clasped to a coil near the bottom of the first encapsulated elastomer thereby
allowing
the first encapsulated elastomer to be fixedly positioned at the periphery of
the opening
in the hollow base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0058] The technical contents, features and effects related to an adjustable
mattress structure are clearly presented in preferred embodiments and
accompanying
drawings.
[0059] Referring to FIGS. 1, 2 and 3 which illustrate partial components of
an adjustable mattress structure. As shown in these figures, the adjustable
mattress
structure comprises a mattress body 100 in which there are a plurality of
hollow bases
1, a plurality of elastic support units 2, a plurality of adjustable
positioning boards 3
and a plurality of spring positioning bodies 4. The hollow bases 1 are
arranged in place
for development of the length and the width of the mattress body 100. Each of
the
hollow bases 1 has a top surface 11 on which openings 111 are designed and an
anterior
side 12 on which an opening 121 is designed and is internally connected
through the
openings 111, 121. At both sides of an opening 111 on the top surface 11 are
opened
two sliding grooves 112; on both lateral walls inside the hollow base 1 are
designed
several slide seats 13 symmetrically arranged from top to bottom for
development of a
positioning mechanism by which an adjustable positioning board 3 is adjusted
in
height.As shown in FIGS. 1 to 3, an adjustable positioning board 3, which
slips into
slide seats 13 through an opening 121 on an anterior side 12 of a hollow base
1, is
coupled with and positioned in the slide seats 13 according to an optional
height. As
such, the adjustable positioning boards 3 in all hollow bases 1 are situated
at same or
distinct heights.
CA 02988177 2017-12-04
[0060] As shown in FIGS. 1 to 3, an elastic support unit 2 placed on the top
surface 11 of a hollow base 1 comprises a first encapsulated elastomer 21 on
which
there are a top 211 as well as a bottom 212 and a second encapsulated
elastomer 22 on
which there are a top 221 as well as a bottom 222. The top 221 of the second
encapsulated elastomer 22 joins the top 211 of the first encapsulated
elastomer 21 so
that the second encapsulated elastomer 22 is suspended and positioned in the
first
encapsulated elastomer 21 and allows the bottom 222 to extend from the bottom
212 of
the first encapsulated elastomer 21.
[0061] Moreover, second encapsulated elastomers 22 suspended in first
encapsulated elastomers 21 are an example in a preferred embodiment which does
not
limit claims herein. A design of second encapsulated elastomers 22 held in
first
encapsulated elastomers 21 should be incorporated in claims herein.
[0062] As shown in FIGS. Ito 3, a first encapsulated elastomer 21 (a second
encapsulated elastomer 22) illustrates at least a spring is wrapped in an
encapsulated
package. (In FIGS. 1 to 3, an encapsulated package made of non-woven fabric or
other
textile materials is indicated with dotted lines in which coil icons as a
spring are
wrapped.)
[0063] The spring positioning body 4 comprises a locating part 41 from
which a first elastic fastener 42 and a second elastic fastener 43 at both
sides extend:
the first elastic fastener 42 and the second elastic fastener 43 at tops are
provided with a
fastening block 421 and a fastening block 431, respective; the first elastic
fastener 42
and the second elastic fastener 43 develop a fastening space in between; the
spring
positioning body 4 comprises two sliding parts 45 extending from the bottom of
the
11
CA 02988177 2017-12-04
locating part 41. The spring positioning body 4 allows two sliding parts 45 to
slip into
the sliding grooves 112 on the top surfaces 11 of two adjacent hollow bases 1
and be
positioned beside the openings 111 so that the two adjacent hollow bases 1 are
not
separated from each other. Moreover, the fastening block 421 on the first
elastic
fastener 42 (the fastening block 431 on the second elastic fastener 43) clasps
one side
of one in two adjacent first encapsulated elastomers 21 so that the two
adjacent first
encapsulated elastomers 21 are positioned in the fastening space 44 of the
spring
positioning body 4. As such, a first encapsulated elastomer 21 is stably fixed
on the top
surface 11 of a hollow base 1, a second encapsulated elastomers 22 extends
into the
hollow base 1 through an opening 111 on the top surface of the hollow base 1,
and each
elastic support unit 2 is positioned on the top surface 11 of a hollow base 1.
[0064] When the elastic support unit 2 is placed on the top surface 11 of the
hollow base 1, the bottom 212 of the first encapsulated elastomer 21 contacts
the top
surface 11 of the hollow base 1 and the bottom 222 of the second encapsulated
elastomer 22 penetrates the opening 111 on the top surface 11 of the hollow
base 1 and
is situated above or resisted by the adjustable positioning board 3.
[0065] As shown in FIG. 1, two adjacent hollow bases 1, which have been
linked and positioned by sliding parts 45 of spring positioning bodies 4 when
all elastic
support units 2 are placed on top surfaces 11 of the hollow bases 1, combine
each other.
Based on the above mechanism, a mattress body 100 which is covered with a
mattress
encasement 5 can be developed finally.
[0066] Referring to FIG. 4 which illustrates a layer of spacer member 46
adheres to two adjacent hollow bases 1 or a layer of spacer member 46 between
two
12
CA 02988177 2017-12-04
sliding parts 45 of a spring positioning body 4 extends downward in order to
avoid
friction-induced noise between two adjacent hollow bases 1. Other structural
components identical to those in FIG. 3 are not further explained.
[0067] Referring to FIG. 5. Different from FIGS. 1 to 3, FIG. 5 illustrates an
elastic carrier 6 integrated with a hollow base 1 internally has two ends
fixed at two
opposite sides of the hollow base 1 lengthwise and is situated at the topmost
end inside
the hollow base 1 and above highest slide seats 13. The elastic carrier 6 is
used to
receive second encapsulated elastomers 22, which are moving downward and not
sinking to the bottom of the hollow base 1 directly, and prevent an adjustable
positioning board 3 from slipping into the hollow base 1 completely. Moreover,
a
second encapsulated elastomer 22 which is pressed downward under stress
overcomes
elasticity of the elastic carrier 6, keeps moving downward and resists an
adjustable
positioning board 3 without failure of any initial function. Other structural
components
identical to those in FIGS. 1 to 3 are not further explained.
[0068] Additionally, the sliding parts 45 of spring positioning bodies 4
correspondingly slide inside but do not directly deviate from the sliding
grooves 112
which are designed as dove-shaped grooves on the hollow base 1.
[0069] Referring to FIG. 6. Different from FIGS. 1 to 3, FIG. 6 illustrates no
spring positioning body 4 but a positioning slot 113 around an opening 111 at
the top
surface 11 of a hollow base 1 directly. The bottom 212 of a first encapsulated
elastomer
21 is directly coupled with and positioned in the positioning slot 113 so that
the first
encapsulated elastomer 21 is peripherally positioned at the opening 111 of the
hollow
13
CA 02988177 2017-12-04
base 1. Other structural components identical to those in FIGS. 1 to 3 are not
further
explained.
[0070] Referring to FIG. 7. Different from FIGS. 1 to 3, FIG. 7 illustrates no
spring positioning body 4 but a clamping member 114 around an opening 111 at
the top
surface 11 of a hollow base 1 directly. The clamping member 114 clasps coils
of a first
encapsulated elastomer 21 near the bottom 212 so that the first encapsulated
elastomer
21 is peripherally fixed at the opening 111 of the hollow base 1. Other
structural
components identical to those in FIGS. 1 to 3 are not further explained.
[0071] As shown in FIG. 8, the first encapsulated elastomers 21 of the elastic
support units 2 support weight of a user 7 who lies down the mattress body
100,
making the second encapsulated elastomers 22 under stress move downward and
resist
the adjustable positioning boards 3. Because each of the adjustable
positioning boards
3 inside one hollow base 1 is manually adjustable in height based on a body
curve,
distinct positions (areas) on the body of a user 7 correspond to adjustable
positioning
boards 3 inside hollow bases 1 at different heights: a second encapsulated
elastomer 22
is less elastically compressed when stress is propagated from the top 221 of
the second
encapsulated elastomer 22 which has the bottom 222 close to the adjustable
positioning
board 3; a second encapsulated elastomer 2 performs different elasticity by
which each
elastic support unit 2 generates distinct elastic force when a distance
between the
bottom 222 of the second encapsulated elastomer 22 and an adjustable
positioning
board 3, which is moved downward and located at a distinct position in a
hollow based
1, is increased. As such, a user 7 whose body curve is adjustably supported by
the
mattress body 100 based on mattress firmness will sleep comfortably.

spirit and scope of the present disclosure should be covered in claims of the
