SPECIFICATION
TITLE: FOLDABLE THERMAL CHAIR
TECHNICAL FIELD
The present invention relates to a foldable thermal chair
in which two support frames with different sizes stably support
a seat part when the foldable thermal chair is in use, while the
support frames form a flat shape and are folded with no part
protruding outwards when the foldable thermal chair is not in
use thereby making it possible to easily store and carry the
foldable thermal chair, and in which a candle-height automatic
adjustment means pre-filed by the present inventor is fastened
to the bottom of the seat part so as to evenly transmit heat to
a user's body thereby making it possible to maintaining the
user's body temperature or to relax the user's muscles etc.
during outdoor activities.
DESCRIPTION OF THE RELATED ART
In general, chairs are a means for a person to sit on and
come in different shapes according to the purposes of use and
according to spaces.
In particular, chairs used for outdoor activities such as
fishing, camping and street vending etc. cannot keep users'
bodies warm and maintain the body temperature in the winter when
outdoor temperature is low. As a means to solve the problem,
chairs capable of installing a briquette etc., a material for
generating heat, thereunder or in the space formed therein can
1
CA 03015605 2018-08-23
be used, or an electric heater or electric pad are used as a
means to generate heat.
In the case of a briquette, the user's skin can be burned
due to high-temperature heat that is generated while the
briquette is burned, and a certain amount of bulky and heavy
briquettes has to be piled for use. This causes inconvenience
to the users. Additionally, an electric heater cannot be used
in places without electricity, and is likely to cause an accident
due to a short circuit caused by humidity in rainy weather or
wet weather.
As a related art, South Korean Utility Model No. 20-0436577
(published on September 7, 2007) discloses a heating chair for
a candle with a height adjustable device, which is capable of
heating a chair by burning a candle inside the chair consisting
of metal, and capable of adjusting the heat generation point of
the candle through a manipulation handle so as to heat the chair
thereby making it possible to effectively maintain users' body
temperature even during outdoor activities.
However, according to the related art, the chair has to
have a space with a certain size such that a candle, a material
for generating heat, is installed inside the chair. Accordingly,
the chair has to be correspondingly configured to have a certain
height and volume. This makes it harder to carry the chair for
outdoor activities such as fishing or camping etc., and to evenly
distribute heat because a part of a seat part is heated through
2
CA 03015605 2018-08-23
the candle, a material for generating heat, so as to directly
transmit the heat to the user's body thereby increasing the
possibility of causing users' skin to be burned due to the
overheated seat part.
As a means to solve the problems, provided is a foldable
thermal chair in which a seat part and each support frame
supporting the seat part are configured to have different sizes
so as to stably support a user's body, while the support frames
form a flat shape and are folded with no part protruding outwards
when the foldable thermal chair is carried or not in use thereby
making it possible to minimize the volume of the chair and to
easily store and carry the foldable thermal chair, in which a
candle-height automatic adjustment means pre-filed by the
present inventor is fastened to the bottom of the seat part so
as to effectively maintain the user's body temperature even
during long-lasting outdoor activities such as fishing or
camping etc. thereby improving the user's convenience, and in
which a store heat dispersion plate, provided at the bottom of
the seat part, receives heat from the candle-height automatic
adjustment means, heats air inside the seat part, and performs
convection by means of the heated air so as to transmit heat to
the seat part thereby efficiently and evenly transmit heat.

11
CA 03015605 2018-08-23
Meanwhile, the stored heat dispersion plate 300 can be
coupled to the stored heat dispersion plate fastening openings
250 of the fixing and fastening part 200, and provided with a
fastening plate coupling part 310 protruding downwards from the
bottom surface of the stored heat dispersion plate 300 such that
the stored heat dispersion plate 300 is regularly spaced apart
from and fastened to the top surface of the fastening plate 210
provided to the fixing and fastening part 200.
Further, the stored heat dispersion plate 300 preferably
is configured as a plate consisting of metal having high thermal
conductivity so as to efficiently absorb heat transmitted from
the candlelight-height automatic adjustment means 500.
As illustrated in FIGS. 1 to 7, the support frame part 400
includes an inner frame 410 and an outer frame 420 so as to be
coupled to the coupling part 120 of the seat part 100 when a
foldable thermal chair is in use or not in use. The inner frame
410 has an inner frame opening part 411 where a part of the
center of the top of the inner frame is cut, and the outer frame
420 is detachably coupled to the hanger 130 of the seat part
100, and has a rectangular shape 422 as in FIG. 4a or a "E"
shape in which the bottom is opened or a part of the bottom is
cut as in FIG. 4b.
Further, the outer frame 420 has a width and length larger
than those of the inner frame 410 such that the inner frame 410
is inserted into the outer frame 420 when a foldable thermal
12
CA 03015605 2018-08-23
chair is folded so as to be carried or stored, and the inner
frame 410 also has a width and length larger than those of the
seat part 100 and the fixing and fastening part 200 such that
the outer frame 420, the inner frame 410, the seat part 100 and
the fixing and fastening part 200 form a flat shape when a
foldable thermal chair is not in use. Accordingly, the support
frame can be folded without any part protruding out of the outer
frame 420 thereby making the foldable thermal chair small enough
to be easily carried and stored.
Additionally, inner frame coupling openings 412 and outer
frame coupling openings 421 are formed at portions of both sides
of the inner and outer frames, where the inner frame 410 and the
outer frame 420 are crossed. Further, fastening bolts 430, a
single body, are inserted into and coupled to all the inner
frame coupling openings 412 and outer frame coupling openings
421 so as to fasten the inner frame 410 and the outer frame 420,
and at the same time, the inner frame 410 and the outer frame
420 can swivel around the fastening bolts 430 and extend so as
to extend the support frame part 400 in an "X" shape for the use
of a foldable thermal chair.
In this case, a means to fasten the inner frame 410 to the
outer frame 420 is not limited to fastening bolts 430.
As in FIG. 6 as an embodiment of the present invention,
the inner frame 410 and the outer frame 420 swivel around the
fastening bolts 430 inserted into and fastened to portions where
13
CA 03015605 2018-08-23
the inner frame 410 and the outer frame 420 are crossed, and
extend in an "X" shape. Then, a hanger 130 is coupled to the top
of the extended outer frame 420 so as to enable the user to sit,
thereby ensuring structural stability.
Further, an extended foldable thermal chair can stably
support the body of the user without collapsing as a result of
the difference between the lengths of the inner frame 410 and
the outer frame 420 even when the center of gravity is changed
in the state where the user sits on the chair.
Further, the fixing and fastening part 200 can be coupled
to the bottom surface of the seat part 100 fastened to the upper
end of the support frame 400. The stored heat dispersion plate
300 is regularly spaced apart by means of the fastening plate
coupling part 310 from the top surface of the fastening plate
210 provided to the fixing and fastening part 200 in the
convection space part 230 formed by the combination of the seat
part 100 and the fixing and fastening part 200 and afterwards,
the candlelight-height automatic adjustment means 500 is
fastened to the bottom surface of the fastening plate 210 so as
to transmit heat from the candlelight-height automatic
adjustment means 500 to the stored heat dispersion plate 300
through the inlet 240 formed at the fastening plate 210.
In this case, the heat transmitted to the stored heat
dispersion plate 300, as illustrated in FIG. 7, heats air inside
the convection space part 230, in which the stored heat
14
CA 03015605 2018-08-23
dispersion plate 300 is installed, such that heat is transmitted
to the bottom surface of the top plate part 110 provided to the
seat part 100 by means of the convection of the heated air, and
air cooled after the convection can be discharged outwards
through air outlets 221 formed at the lateral side support part
220 of the fixing and fastening part 200.
Further, the stored heat dispersion plate 300, as
illustrated in FIG. 10, is configured to be convex, not to be
flat, and can be replaced with a ventilator 320 for preventing
an increase in pressure of inner air.
Meanwhile, when a foldable thermal chair is not in use,
the hanger 130 fastened to the upper end of the outer frame 420
is separated from the outer frame 420, and the outer frame 420
and the inner frame 410 are re-swivel around the fastening bolts
430 such that the foldable thermal chair is folded.
In this case, because the outer frame 420 has a width and
length larger than those of the inner frame 410, the inner frame
410 is inserted into the outer frame 420, and the fixing and
fastening part 200 coupled to the bottom surface of the seat
part 100 is also inserted into the inner frame 410 having a
width and length larger than those of the fixing and fastening
part 200. Accordingly, the outer frame 420, the inner frame 410,
the seat part 100 and the fixing and fastening part 200, as
illustrated in FIG. 6, form a flat shape so as to be folded
without any part protruding out of the outer frame 420 thereby
CA 03015605 2018-08-23
making a foldable thermal chair small enough to be easily carried
and stored.
Additionally, according to the present invention, the
above-described inner frame 410 can be coupled to the coupling
part 120 and the above-described outer frame 420 can be
detachably coupled to the hanger 130. Surely, the above-
described inner frame 410 can also be detachably coupled to the
hanger 130, and the above-described outer frame 420 can also be
coupled to the coupling part 120.
Meanwhile, according to another embodiment of the present
invention as illustrated in FIG. 8, each of the inner frame 410
and the outer frame 420 of an embodiment of the present invention
separately consist of a top frame 410a, 420a and a bottom frame
410b, 420b.
Herein, the above-described fastening bolts 430 are
inserted into and fastened to coupling openings 412a, 412b, 421a,
421b respectively penetrating and formed at portions where the
inner frame 410 and the outer frame 420 are mutually crossed,
so as to assemble the top frame 410a, 420a and bottom frame 410b,
420b.
In particular, according to another embodiment of the
present invention, the top frame 410a, 420a has a diameter
smaller than that of the bottom frame 410b, 420b, and the top
frame 410a, 420a is partially inserted into the bottom frame
16
CA 03015605 2018-08-23
410b, 420b such that the top frame and the bottom frame are
assembled.
That is, the bottom of the top frame 410a, 420a is
partially inserted into the top of the bottom frame 410b, 420b
having a hollow inside, and afterwards, the fastening bolts 430
are inserted into and fastened to the coupling openings 412a,
412b, 421a, 421b so as to assemble the top frame and the bottom
frame. By doing so, the top frame and the bottom frame are easily
assembled, thereby creating convenience in production.
Additionally, the state where the top frame 410a, 420a and
the bottom frame 410b, 420b are coupled is illustrated in the
sectional view of FIG. 8. Suppose the thickness of both sides
of the top frame 410a, 420a and the bottom frame 410b, 420b
except for the inner hollow thereof is respectively "T". If the
support frame consists of one inner frame 410 and one outer
frame 420 respectively as in an embodiment of the present
invention, the total of the thickness of a portion supported by
the fastening bolts 430 is "4T". However, if the inner frame 410
and the outer frame 420, as described above, are configured to
have a double frame coupling structure which consists of a top
frame 410a, 420a and a bottom frame 410b, 420b, the total of the
thickness of a coupled portion supported by the fastening bolts
430 is "8T". By doing so, the fastening bolts strongly support
a coupled portion, thereby stably improving the durability of
the inner frame 410 and the outer frame 420.
17
CA 03015605 2018-08-23
Meanwhile, according to yet another embodiment of the
present invention as illustrated in FIG. 9, each of the inner
frame 410 and the outer frame 420 of another embodiment of the
present invention separately consist of a top frame 410a, 420a
and a bottom frame 410b, 420b, and as illustrated above, the
above-described fastening bolts 430 are inserted into and
fastened to the coupling openings 412a, 412b, 421a, 421b
respectively penetrating and formed at portions where the inner
frame 410 and the outer frame 420 are mutually crossed so as to
assemble the top frame 410a, 420a and the bottom frame 410b,
420b.
The diameter of the top frame 410a, 420a is the same as
that of the bottom frame 410b, 420b, wherein the top frames 410a,
420a are provided with round bar members B whose part protrudes
outwards and which are coupled to the inside of the top frame,
and protruding portions of the round bar members B are inserted
into the bottom frames 410b, 420b in the state where coupling
openings 412a, 421a are formed at protruding ends of the round
bar members B so as to assemble the top and bottom frames.
Herein, the round bar members B have a rod shape without
a hollow inside unlike the top frame 410a, 420a and the bottom
frame 410b, 420b. As illustrated in FIG. 9, the thickness of
coupled portions supported by the fastening bolts 430 through
the above-described round bar members B becomes thicker. By
doing so, the durability of the inner frame 410 and the outer
18
CA 03015605 2018-08-23
frame 420 are improved. As in another embodiment of the present
invention, the gap between the appearances of the inner frame
and outer frame, which is caused by the differences in the
diameter of the top frame 410a, 420a and bottom frame 410b, 420b,
can be bridged, thereby ensuring the aesthetics of the
appearances of the inner frame 410 and outer frame 420.
Meanwhile, a foldable thermal chair according to yet
another embodiment of the present invention includes a seat part
100, a fixing and fastening part 200, a store heat dispersion
plate 300, a support frame part 400 and a candlelight-height
automatic adjustment means 500 as described above.
The seat part 100, as illustrated in FIGS. 11 and 12,
includes a cover part 140 consisting of fabric with thickness
and provided with an opening and closing member 141 for opening
and closing the inside of the seat part, a cushion member 150
having thickness and installed inside the cover part 140, a
coupling part 120 consisting of metal, having a pipe shape whose
longitudinal section is round or polygonal, and provided at a
portion extended on one side in the widthwise direction of the
cover part 140, and a hanger 130 consisting of metal, having a
hook-shaped longitudinal section, and attached and fixed to a
portion extended on the other side in the widthwise direction
of the cover part 140 by means of sewing, riveting or attachment
etc.
19
CA 03015605 2018-08-23
In this case, the fabric can be any one selected from
natural resins such as usual cotton, hemp cloth, ramie, or linen
etc., or synthetic resins, and usual zippers, snap buttons,
buttons or Velcro tapes etc. can be used as the opening and
closing member 141.
In particular, the hanger 130 has arranging grooves 131 on
the inner surface thereof, and the outer frame 420 has arranging
protrusions 423 at the top thereof at positions corresponding
to those of the arranging grooves 131 so as to couple the
arranging protrusions to the arranging grooves 131. Conversely,
the hanger 130 has arranging protrusions 132 the inner surface
thereof, and the outer frame 420 has arranging grooves 424 at
the top thereof at positions corresponding to those of the
arranging protrusions 132 so as to couple the arranging grooves
to the arranging protrusions 132.
By doing so, in the state where the user sits on the seat
part 100, a position where the seat part 100 and the outer frame
420 are coupled is fixed such that the user can control the
movement of the seat part 100, thereby ensuring stability of a
foldable thermal chair in use and preventing damage to the
support frame 400. This is applicable to all the embodiments of
the present invention.
Additionally, the arranging grooves 131, 424 formed on the
tops of the hanger 130 and the outer frame 420 can be configured
CA 03015605 2018-08-23
to have a hole shape corresponding to the arranging protrusions
132, 423.
Meanwhile, the above-described inner frame 410, as
illustrated in FIG. 13, has a guide groove 413 along the
circumference of the longitudinal section thereof at the top
thereof, and the coupling part 120 has one or more guide
protrusions 121 protruding inwards at a position corresponding
to that of the guide groove 413.
In this case, the guide groove 413 is preferably formed at
the center of the inner frame 410 in the widthwise direction
thereof at the top thereof, and can also be configured as a hole
penetrating the guide groove such that one or more of the above-
described guide protrusions 121 are inserted and come into close
contact on both sides in the widthwise direction of the inner
frame.
Further, the guide protrusion 121 is configured to protrude
towards the inside of the coupling part 120. The guide protrusion
can be configured to protrude to some degree from the inner
surface of the coupling part when the coupling part 120 is formed
for the first time, and usual bolts or set screws etc. can also
be inserted and fastened along the circumference of the
longitudinal section of the coupling part 120 so as to protrude
towards the inside of the coupling part 120 in the state where
the inner frame 410 is coupled to the coupling part 120.

By doing so, in the state where the user sits on the seat
part 100, a position where the seat part 100 and the inner frame
410 are coupled is fixed such that the user can control the
movement of the seat part 100, thereby ensuring stability of a
foldable thermal chair in use and preventing damage to the
support frame 400. This is applicable to all the embodiments of
the present invention.
Additionally, when a foldable thermal chair is in use, or
when it needs to be stored, the seat part 100 can rotate in the
state where the inner frame 410 is coupled and fixed to the
coupling part 120. In this case, the guide protrusion 121 guides
the rotation of the seat part 100 in the state where the guide
protrusion 120 is fitted into the guide groove 413, and blocks
the movement of both sides of the seat part 100 so as to stably
rotate the seat part when the seat part 100 rotates.
Further, the above-described guide protrusion 121 is
provided to the coupling part 120, and the above-described guide
groove 413 is formed at the inner frame 410. However, grooves
or holes can be formed at the coupling part 120, and protrusions
can be formed at the inner frame 410 according to convenience
in manufacture, assembly and use of a foldable thermal chair.
Meanwhile, according to a foldable thermal chair of yet
another embodiment of the present invention, a seat part 100,
as illustrated in FIG. 11, includes a cover part 140 consisting
of fabric with thickness and provided with an opening and closing
22
CA 03015605 2018-08-23
member 141 for opening and closing a convection space part formed
therein, and a thermal module 160 installed at the convection
space part inside the cover part 140.
By doing so, heated air inside the convection space part
equipped with the thermal module 160 that generates heat on its
own transmits heat to the top plate part of the seat part 100.
This enables the user to maintain the body temperature during
outdoor long-lasting activities such as fishing or camping etc.
without a candlelight-height automatic adjustment means 500 pre-
filed by the present applicant. Further, this makes it possible
to simplify the structure of a foldable thermal chair because a
candlelight-height automatic adjustment means 500 does not need
to be coupled.
Meanwhile, according to a foldable thermal chair of yet
another embodiment of the present invention, a seat part is
provided with a pocket into which a thermal module can be
inserted, a coupling part consists of fabric such that a metallic
pipe is separately installed, and a hanger can be wrapped in
fabric. By doing so, a foldable thermal chair of the present
invention has the advantage of generating heat on its own through
the above-described thermal module, and of separating and
coupling the seat part and the support frame easily. This makes
it possible to readily carry and store a foldable thermal chair.
The present invention has been described with reference to
specific items such as elements etc. limited embodiments and
