As illustrated in the drawings, when one is disposed in one place, it is hinged to both the first guide link part 430a and the second guide link part 430b. If a plurality of spaced apart from each other can be hinged separately, the first guide shaft portion (410a) and the second guide link portion (430b) forming a hinged connection with the first guide link portion (430a). It is conceptually distinguishable by the second guide shaft portion 410b forming a hinge coupling with the . In the drawing, the guide shaft portion 410 is positioned at a straight line spaced apart from the guide rail portion 420 , and corresponds to the guide shaft groove 411 configured on one side of the gas burner extension 200 and the guide shaft groove 411 . Thus, the guide shaft groove 412 configured on one side of the guide link part 430 is gathered together on one side of the guide rail part 420 to form the guide shaft part 410 . The two guide shaft grooves 411 and 412 are formed of a shaft and a groove to form a hinged connection with each other. In addition, when the guide rail part 420 is installed in the receiving part 110 of the gas burner or other places, the position may be changed to function accordingly.

It has a straight or curved length to serve as a rail 421 guiding the movement m41 of the support shaft portion 460 . It is provided independently from the gas burner and may have a configuration that can be separately installed or detached from the gas burner. Alternatively, it may be fixedly provided in the gas burner, and in this case, it may be disposed in the receiving unit 110 or other components of the gas burner, and it is advantageous for the functional implementation to follow the length in the direction of arrangement. The drawing shows a rail 421 disposed on the extension part 200 of the gas burner and formed by making a straight groove along the length of the extension part 200, and the support shaft part 460 is interposed (fitted) on the rail 421. It is a configuration that can slide and move in a straight line. The upper part of the support shaft part 460 is interposed in the rail 421 and assembled to form a single component, so it can be conceptually viewed as a component of the guide rail part 420, and it can be viewed as a rail moving piece 422 ( It is called

Guide link unit 430,

As a link having a length made of a member such as metal or synthetic resin, the drawing illustrates the rectangular flat plate shape. One side of the guide link part 430 is hinged by putting a hinge shaft on the guide shaft part 410, and the other side is hinged by putting a hinge shaft on the support link part 440, which is referred to as the link shaft part 450. The figure illustrates that the first guide link part 430a and the second guide link part 430b are arranged in a V shape so that one side of each is hinged to the guide shaft part 410 .

Support link portion 440,

As a link having a length made of a member such as metal or synthetic resin, the drawing illustrates the shape of a rectangular flat plate. From the lower side of the combustion unit 310, connecting the vertical support parts d1 on both sides of the supporting part 320 facing each other in the shape of have. Alternatively, the support link part 440 may be separately manufactured and provided in a form coupled to the vertical support part d1 of the support part 320 . And as shown in the drawing, it may be formed as a straight body or provided in a state in which one side and the other side are coupled to each other around the support shaft portion 460 . The guide link part 430 includes a first support link part 440a and a second support link part 440b which are respectively disposed on the left and right sides of the combustion unit 310, both of which are arranged to intersect in an X shape in plan view. And it is configured to be folded (m42) like scissors using the support shaft portion 460 as a hinge axis. In a broad sense, the support link part 440 includes the support part 320 .

Link shaft portion 450,

It is a hinge shaft that is hinged so as to link the other side of the guide link part 430 and one side of the support link part 440 . Here, one side of the support link part 440 refers to between one end of the support link part 440 and the support shaft part 460 .

The first link shaft portion 450a is formed by hinged coupling of the other side portion of the first guide link portion 430a and one side portion of the first support link portion 440a, and the second link shaft portion 450b is the second guide link. The other side of the portion 430b and the second supporting link portion 440b are hinged together. Here, the other side of the guide link part 430 and one side of the support link part 440 may be formed of a shaft and a groove to form a hinged connection.

Support shaft portion 460,

It is located in the middle of the body of the support link portion (440). That is, it is positioned at the intersection of the first support link part 440a and the second support link part 440b, which are arranged to cross each other in the X state, and the hinge shaft is configured to be hinged. And it is constrained to the guide rail part 420 and has a configuration that can move limited along the length, which in addition to the configuration of the hinge shaft, a corresponding shape that can be interposed in the rail 421 of the guide rail part 420 Take it to form a coupling so that sliding movement is possible. In the drawing, the support shaft portion 460 has a shaft formed to protrude upward of the hinged portion, and this shaft is provided as a rail moving piece 422 to fit into the groove formed in the guide rail portion 420 is illustrated. On the other hand, the rail moving piece 422 may be separately configured and slidably assembled on the rail 421 , and the supporting shaft portion 460 may be coupled to the rail moving piece 422 to move together.

Next, the operation and effect made through the above-described configuration will be looked at. Reference is made to the examples shown in FIGS. 4 and 5 in this regard.

In the operation (m40) of the folding means 400, first, it is assumed that the position of the support shaft portion 460 is placed on the other side of the guide rail portion 420. At this time, the guide shaft portion 410, the support shaft portion 460, the first link shaft portion (450a) and the second link shaft portion (450b), respectively, the first guide link portion 430a and the second guide link assembled by a hinge coupling through the shaft portion (450b). The part 430b, the first support link part 440a, and the second support link part 440b are folded in a rhombus shape, so that the folding means 400 is in the folding mode. See the example of Figure 4A.

Next, when the user pushes any one part of the folding means 400 (support link part 440, support part 320, etc.) toward one side of the guide rail part 420, the support shaft part 460 is the guide rail part. While sliding along the length of 420 (m41), the distance between the support shaft portion 4 and the guide shaft portion 410 is narrowed, and at the same time, the first link shaft portion 450a and the second link shaft portion ( 450b) is spaced apart. Accordingly, the folded state in the rhombus shape in the folding mode starts to unfold into a square shape, and the folding means 400 gradually progresses to the unfolding mode, the folding m42 is made. See the example of Figure 4B.

And when the movement (m41) and folding (m42) according to the operation (m40) of the folding means 400 proceeds, the first guide link part 430a and the second guide link part 430b become a straight line and fold (m42) There is a dead point at which the state of is the maximum deployment n1. At this time, the operation m40 of proceeding to the unfolding mode can be completed. Therefore, one movement (m41) and folding (m42) of the folding means 400 are interlocked with one operation (m40), so that a plurality of (4) support parts 320 disposed around the combustion unit 310 are formed. The effort of folding (m42) one by one can be reduced. See the example of Figure 4C.

However, in the state of the dead point above, it is possible to promote further movement (m41) and folding (m42). In this case, the first guide link part 430a and the second guide link part 430b are opposite to the original one. The state of folding (m42) proceeds in a state of being bent and folded in the direction (reverse direction), and the state of the folding (m42) proceeds from the unfolding mode to the folding mode again. That is, it becomes a reverse unfolding (n2) state that develops in the opposite direction. If initially, the elastic member 470 (rubber) between the first support link part 440a and the second support link part 440b or between the first guide link part 430a and the second guide link part 430b. , spring, etc.) is interposed and connected, it works to go back to the folded mode state after passing the dead point where the unfolding mode and the folding mode change. However, since the support shaft portion 460 is caught at the end of the guide rail portion 420 and can no longer move (m41), the operation (m40) of the folding means 400 is stopped and fixed in a state in which it has progressed to a certain extent. The stability of the folded (m42) state can be sustained. See FIG. 4D in this regard.

On the other hand, it is possible to return to the original state by reversely proceeding the operation (m40) of the folding means 400 so far. In addition, if the elastic member 470 is mounted, a forced operation (m40) is performed by the user's external force until the example of FIG. 4C, but then automatically returns to the original state by the elastic restoring force from the example of FIG. 4B (m40) is possible. Therefore, there is no need to keep touching the heated area because you only need to push it once as if you were touching it for the first time.

In particular, when using a gas burner in relation to the example of FIG. 5 , the door 14d is opened by opening and closing (m10), and the extension part folding operation (m20) is performed to move the extension part 200 to the outside of the supply part 100 After moving the folding means 400 to a position where the operation (m40) is possible by unfolding it, the folding means 400 is operated (m40) to unfold the support part 320 . At this time, the folding means 400 waits for the other side of the guide rail part 420 for easy storage, and then moves by sliding movement (m41) to one side so that the support part 320 is the combustion part of the cooking part 300 . It acts to be positioned above (310). When the gas burner is not used, the folding means 400 is reversely operated (m40) to fold the support part 320 to its original state, and the extension part folding operation (m20) is reversed to return the extension part 200 to its original state. After moving the folding means 400 to the inside of the supply unit 100, the door 14d is reversely opened and closed (m10) to close it in its original state to store the folding means 400 built into it.

In the above description, folded means a folded or unfolded state, that is, a folded mode or an unfolded mode state. One side (or the other side) includes the end of either (or the other) side, as well as elsewhere less than or spaced from the end. Here, one side part and the other side part can be used interchangeably as a relative concept. Also, the first and the second may be used interchangeably as a relative concept. Provision, formation, perforation, etc. are terms that make up the composition and can be used interchangeably in situations where the meaning is common. Hinge coupling may refer to known techniques, for example, may be configured by inserting a hinge shaft into a hinge groove to be bent. The shaft is provided by forming or protruding to have a length, and the groove is provided by digging out or drilling a part (or all) of it.
