After placing the gas burner on the floor as shown in Figure 7 A and settling it, the user rotates (deploys) the supply part 100 by hand with respect to the extension part 200 (not shown) in Figures 7 B and 8 A. When folding (f1), the hinge connection (100-321) orbits around the hinge connection (200-100) (f2),

The orbital rotation (f2) of the hinge connection (100-321) gives (moves) a positional movement (f3) to the connector 321, and the positional movement (f3) is transmitted to the hinge connection (321-322), thereby forming a hinge connection. The hinge connection (321-322) rotates (f4) around (311-322), that is, the rotation operation unit (322) rotates (f4),

When the rotation operation unit 322 rotates (f4), the hinge connections (322-323) rotate around the hinge connections (311-322) and perform the same (concentric) orbital rotation (f4),

When the hinge connection (322-323) performs orbital rotation (f4), the sliding rotation (f5) (sliding and rotating at the same time) of the sliding hinge portion 323 is performed through the sliding hinge connection (311-323). , the folding (f6) of the support portion 320 is automatically linked.

At this time, when switching from the folded mode to the unfolding mode (unfolding operation state), the supply unit 100 is initially adjacent to the support unit 320, so when the support unit 320 is immediately unfolded, the supply unit 100 and Interference (contact) may occur. To avoid this problem, the folding device of the present invention,

Through the sliding hinge connection (311-323), the initial rotation motion (rotational energy) of the supply unit 100 is mainly converted to an expansion/contraction motion (sliding movement) of the support unit 320, thereby greatly increasing the unfolding motion of the support unit 320. It doesn't happen (it doesn't unfold much).

However, after a certain degree of sliding (stretching motion) is achieved, the sliding movement gradually decreases and the unfolding motion begins in earnest. At this time, the supply unit 100 has already left the interference range of the unfolding operation of the support unit 320, so no interference occurs.

Meanwhile, when folding the gas burner for portable storage, it operates in the reverse direction of the process so far.

In the above, terms such as composition (equipment, formation), device (installation), protrusion, perforation (hole), arrangement (position), connection (extension, combination), fixation, etc. can be used interchangeably if the meaning is clear. there is. The longitudinal direction refers to a direction parallel to the length of the extension portion 200. A hinge connection refers to a connection that can be rotated or bent through a hinge configuration. Rotation by hinge connection refers to bending the bending axis at a predetermined angle so that two members having the same length as the arms are folded, or rotating a rotating member such as a wheel (at a predetermined angle) around the central axis. Folding refers to the switching between unfolding mode (unfolded state) and folded mode (folded state).
