Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a mattress for bed and more
particularly, to a breathing mattress. The invention relates also
to the method of making the breathing mattress.
[0003] 2. Description of the Related Art
[0004] Latex and foam materials have been intensively used for
making mattress for bed. A latex or foam material mattress gives a
comfort support to the user when the user is lying on the mattress.
However, when the user is lying on a latex or foam material
mattress for a certain length of time, the temperature and humility
in the contact area between the user's body and the mattress will
become high, causing the user to feel uncomfortable. In order to
eliminate this problem, breathing structure may be added to the
mattress. However, conventional mattresses having a breathing
structure are commonly expensive.
SUMMARY OF THE INVENTION
[0005] It is one objective of the present invention to provide a
breathing mattress for bed, which provides good ventilation.
[0006] It is another objective of the present invention to provide
a breathing mattress, which is easy and inexpensive to
manufacture.
[0007] To achieve these objectives of the present invention, the
breathing mattress comprises a mattress body, which has a plurality
of mounting holes, and a plurality of hollow elastic filler
elements that are respectively mounted in the mounting holes for
ventilation.
[0008] The present invention also provides a method of making a
mattress comprising the steps of a) preparing a mold having a
cavity and a plurality of upright pins in said cavity; b)
preparing, equal to the number of said upright pins, a plurality of
hollow elastic filler elements, and then sleeving said filler
elements onto said upright pins respectively; c) filling up said
cavity of said mold with a fluid foam material; and d)
shape-forming and hardening said foam material so as to obtain the
mattress.
[0009] The present invention provides still another method of
making a mattress comprising the steps of a) preparing a plurality
of hollow elastic filler elements and a mattress body of foam
material; b) making a plurality of mounting holes in said mattress
body; and c) fastening said filler elements to said mounting
holes.

DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring to FIGS. 1 and 2, a breathing mattress 10 in
accordance with the preferred embodiment of the present invention
is shown comprised of a mattress body 11, and a plurality of filler
elements 20. The mattress body 11 is made by latex or any of a
variety of foam materials, having a top wall 12, a bottom wall 14,
and a plurality of cylindrical mounting holes 16 extending from the
top wall 12 toward the bottom wall 14. The number of the filler
elements 20 is equal to the number of the cylindrical mounting
holes 16. The cylindrical mounting holes 16 are formed in the
mattress body 11 over the area on which the user's body may rest.
The filler elements 20 are hollow cylindrical elastic plastic
members, having an annular cross section in transverse direction
and a corrugated cross section in longitudinal direction. The
filler elements 20 are respectively axially press-fitted into the
cylindrical mounting holes 16.
[0016] As shown in FIGS. 3-5, the fabrication method of making the
aforesaid mattress 10 includes:
[0017] step 1: preparing a mold 50 having a cavity 52 and a
plurality of upright pins 54 in the cavity 52 as shown in FIG.
3;
[0018] step 2: preparing, equal to the number of the upright pins
54, a plurality of cylindrical elastic plastic filler elements 20
that have an annular section in transverse direction and a
corrugated section in longitudinal direction, and then sleeving the
filler elements 20 onto the upright pins 54 respectively as shown
in FIG. 4;
[0019] step 3: filling up the cavity 52 of the mold 50 with a fluid
molding material (latex or foam material) 56 and keeping the filler
elements 20 peripherally maintained in contact with the fluid
molding material 56 as shown in FIG. 5; and
[0020] step 4: hardening the molding material 56 and then removing
the finished product, i.e., the mattress 10 from the mold 50 after
form-setting.
[0021] Referring to FIG. 1 again, when the user lies on the top
wall 12 of the body 11, the elastic material property of the
mattress body 11 gives a comfort support to the user's body, and at
the same time, the user's body is kept in close contact with the
top wall 12 of the mattress body 11 and the top side of each filler
element 20, allowing warn and wet air to pass downwardly away from
the user's body into the gaps in the inside of the filler elements
20.
[0022] As indicated above, the present invention provides a
breathing mattress for bet, which gives a comfort support to the
user and, which is easy and inexpensive to manufacture.
[0023] Alternatively, the breathing mattress can be made by:
preparing a mattress body from latex or foam material and a number
of hollow filler elements, and then making a plurality of mounting
holes in the top wall of the mattress body through a mechanical
processing process, and then fastening the hollow filler elements
to the mounting holes in the top wall of the mattress body.
