[0002] The present invention relates to a portable collapsible fire pit. Background Art

[0003] The inventor of the present invention is an outdoor enthusiast who enjoys traveling long distances by vehicle. Summary of the Invention Problem to be Solved by the Invention

[0004] One of the biggest problems he has encountered during traveling is that he has to set up a grill for cooking, disassemble it after use, and then store the grill. Usually, when storing the grill, he himself or the vehicle gets soiled.

[0005] Furthermore, when bringing a grill on a road trip, there is a problem that the grill is prone to tipping over inside the vehicle due to its unstable structure.

[0006] In addition, when going hiking away from the vehicle during camping, he may be caught in severe cold. In such cases, he sometimes has to dig the ground in an uninhabited area to make an improvised fire pit to warm himself. Means for Solving the Problem

[0007] In view of the above problems, the inventors have come up with the present invention, which is lightweight, collapsible, easy to carry, and can also be used as an outdoor cooking grill.

[0008] This invention is designed to be easily attached to a backpack when retracted, and to be able to be laid flat inside a vehicle.

[0009] The present invention relates to a portable, retractable fire pit. The retractable fire pit comprises a ring-shaped base, a first ring extending upward from the ring base, and a second ring extending upward from the first ring. The retractable fire pit of the present invention has a configuration in which it is fixed and extended using an L-shaped guide and a pin.

[0010] One of the objectives of the present invention is to provide a retractable travel fire pit that can be easily stored inside a vehicle.

[0011] Another objective is to provide a retractable fire pit that can be used as an emergency stove.

[0012] Another objective is to provide a retractable fire pit that can be easily stored inside a backpack.

[0013] Another objective is to provide military personnel with a tactical, retractable fire pit that can be used during covert missions.

[0014] Another objective is to provide a retractable fire pit that can be laid flat inside a transport vehicle and does not invert during transport.

[0015] Another objective is to provide a retractable fire pit that can prevent injuries if an animal accidentally touches the outer wall while burning.

[0016] Another objective is to provide a retractable fire pit for campers that can be easily stored after use and does not soil the vehicle.

[0017] These and other features, embodiments, and advantages will be better understood by referring to the following description, the attached claims, and the drawings. [Brief explanation of the drawing]
