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.
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 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 Sep. 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 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.
As a means to solve the above-described problems, provided is a foldable thermal chair in which two support frames with different sizes extend in an “X” shape so as to stably support a user's body despite the changes in the center of gravity of the user's body when the foldable thermal chair is in use, and a small frame is inserted into a large frame so as to form a flat shape including the seat part with no part protruding out of the large frame when the foldable thermal chair is carried or not in use.
Further, provided is a 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 maintain the user's body temperature even during long-lasting outdoor activities such as fishing or camping etc., and a stored heat dispersion plate is provided to the seat part so as to receive heat from the candle-height automatic adjustment means, heat air inside the seat part, and then evenly transmit heat to the seat part by means of the convection of the heated air.
As a means to solve the problems, provided is a foldable thermal chair including a seat part which can transmit, to the body of a user, heat supplied by a candlelight-height automatic adjustment means in the state where the user sits on the seat part, a fixing and fastening part which enables the candlelight-height automatic adjustment means to be fasted to the bottom surface thereof, a stored heat dispersion plate which can evenly transmit heat to the body of the user as a result of heating the air in a space formed by the connection of the fixing and fastening part and the seat part by means of the heat transmitted from the candlelight-height automatic adjustment means, and a support frame part which extends in an “X” shape when the foldable thermal chair is in use and is folded without any part protruding towards the outside when the foldable thermal chair is not in use.
