  Specifically, in addition to the stainless steel that is the base material, aluminum or copper as the sealability improving material 16 is used to join different metals together, and thermal expansion when these different metals are heated. The difference in coefficient is used to improve the sealing performance. For example, the first-stage cylindrical body 1 that is the uppermost part is formed of stainless steel, and the second-stage cylindrical body 1 is made of aluminum or copper. The third-stage cylindrical body 1 may be formed of a stainless steel material, and may be configured by alternately arranging a stainless steel material and an aluminum material or a copper material. The sealability-improving material 16 is partially formed at positions where the lower end side inner peripheral surface of the outer peripheral side cylindrical body 1 and the seal portion 6 of the upper end side outer peripheral surface of the inner peripheral side cylindrical body 1 or the bottomed cylindrical body 1a are formed. As a structure with attached aluminum or copper You may do it.

The first support rod body 4a or the second support rod body 4b is formed with a female screw portion to be screwed with the male screw portion, or the tension adjusting portion 7 is provided with a female screw portion at both ends. If a male screw part that is screwed with the female screw part is formed on the support bar body 4a or the second support bar body 4b, and one end side is reversely screwed and the tension adjusting part 7 is turned in one direction, the tension adjustment When the portion 7 and the first support bar 4a or the second support bar 4b are separated from each other and the length of the tension support bar 4 becomes longer and is turned in the other direction, the tension adjusting unit 7 and the first support bar The body 4a or the second support bar 4b is approached and stretched. Length of 4 is configured to be shorter.

  In addition, the tension support bar 4 is configured to be detachably provided on the pan body 3, and can be detached from the pot body 3 only when the tension support bar 4 is bent in a predetermined direction. It is configured as follows.

  Specifically, an uppermost side fitting portion 10 that is fitted and locked to one end portion of the first support rod 4 a is provided on the outer peripheral surface of the cylindrical body 1 that is the uppermost portion of the pan body 3. A lowermost fitting part 11 is provided on the outer peripheral surface of the bottomed cylindrical body 1a which is the lowermost part to be fitted and locked with one end of the second support bar 4b, and the uppermost fitting part 10 is first supported. One end portion of the rod body 4a is detachably provided, and one end portion of the second support rod body 4b is detachably provided at the lowermost fitting portion 11 so that the support rod body 4 is detachably provided on the pan body 3. It is configured.

  In addition, the tension support bar 4 is predetermined in a predetermined direction so that it does not easily come off from the pan body 3 during normal use and the pan body 3 is degenerated and the contents during cooking are not spilled. Only when it is set as the angle bending state, it is set as the structure which can be attached or detached with respect to the pan body 3.

  Specifically, the uppermost side fitting portion 10 on the side of the pan body 3 is formed by projecting a columnar body 10a in the horizontal direction on the outer peripheral surface of the cylindrical body 1 which is the uppermost portion of the pan body 3. The protrusion 10b is provided on the tip side peripheral surface of the body 10a, and the lowermost side fitting part 11 is formed in a D-shaped tip side inlet shape for inserting one end of the second support bar 4b. The inner peripheral surface from the distal end side to the proximal end side is formed in a circular shape, and is configured to project in the horizontal direction on the outer peripheral surface of the bottomed cylindrical body 1a that is the lowest part of the pan body 3.

  Further, both ends of the tension support bar 4 fitted to the respective fitting parts 10 and 11 on the pan body 3 side configured as described above, that is, one end of the first support bar 4a and the second support bar. As for one end of the body 4b, one end of the first support rod 4a is formed with a circular through hole 12 at one end formed in a circular shape, and the inner peripheral surface on which the through hole 12 is formed is the outermost surface. The groove portion 13 that fits the convex portion 10b provided in the upper side fitting portion 10 is formed in a direction orthogonal to the inner peripheral surface direction, and one end portion of the second support rod 4b has a D-shaped cross section. The configuration is formed in a shape.

  The both ends of the tension support bar 4 formed in this way are the uppermost side fitting part 10 provided on the pan body 3 and only when the tension support bar 4 is bent at a predetermined angle to the predetermined direction side. It becomes detachable from the lowermost fitting part 11 and is bent or upright in a state other than the predetermined direction side in a state in which the support rod 4 is fitted to the uppermost fitting part 10 and the lowermost fitting part 11. In this case, the convex portion 10b of the uppermost fitting portion 10 and the concave groove portion 13 of the first support rod 4a are not fitted, and the shape of the entrance / exit of the lowermost fitting portion 11 and the second support rod The shape of the one end side of the body 4b does not match and cannot be pulled out.

  In addition, the tension support bar 4 is provided with a slide lock mechanism 5 that prevents the tension support bar 4 from bending and maintains an upright state while maintaining the extended state of the pan body 3.

  Specifically, the slide lock mechanism 5 is formed in a cylindrical shape and is slidably provided on the tension support bar 4, and automatically when the pot body 3 is slid and stretched to bring the tension support bar 4 upright. The first support bar 4a and the second support bar 4b are slid and fitted into a continuous portion 8 in which the first support bar 4b and the second support bar 4b are connected, and the bending of the tension support bar 4 is prevented.

  More specifically, in this embodiment, the slide lock mechanism 5 is formed in a circular cylindrical body 5, and the circular cylindrical body 5 is loosely fitted on a tension support bar 4 formed in a round bar shape. The strut support bar 4 serves as a guide and freely slides up and down.

  That is, the circular cylindrical body 5 as the slide lock mechanism 5 is moved continuously by hand even when the support body 4 is in an upright state from the bent state and the pan body 3 is lowered to the extended state. Even if it is not fitted, it slides downward due to its own weight, abuts and locks on the slide lock abutting portion 14 provided on the second support rod 4b, and is fitted on the continuous portion 8, Even when the main body 3 is put into a degenerate polymerization state, the bottom 2 side of the pan main body 3 is arranged upside down without pushing up the circular cylindrical body 5 by hand and detaching it from the connecting portion 8. In this way, the circular cylindrical body 5 is slid downwardly by its own weight (on the side of the cylindrical body 1 that is the uppermost portion of the pan body 3) and easily detached from the connecting portion 8.

  Further, in this embodiment, when the handle portion 9 is foldably provided on the cylindrical body 1 which is the uppermost portion of the pan body 3 and the pan body 3 is brought into a degenerate polymerization state, the handle portion 9 is folded. 9 contacts the bottom 2 of the bottomed cylindrical body 1a and is configured to hold the pan body 3 in a non-slidable state.

  Specifically, the handle portion 9 is formed into a slender frame that can hold a metal rod-like body, and the base end portion of the handle portion 9 can be rotated to the handle attachment portion 15. The configuration is provided.

  In the present embodiment, the handle portion 9 is configured as a one-handed pan with a cantilever handle, but the handle portion 9 may be provided in an opposing position to form a two-handed pan.

  Since the present embodiment is configured as described above, it has the following operational effects.

  When carrying and carrying the present embodiment, the tubular body 1 and the bottomed tubular body 1a forming the pan body 3 are slid and degenerated, and the respective tubular bodies 1 are in a superposed state, and the pan body 3 Since the height is reduced and it becomes compact and suitable for storage, for example, it can be carried with other luggage without being bulky when stored in a transport bag such as a rick sack. It becomes a telescopic pan that is extremely portable and can carry cooking utensils together efficiently.

  Moreover, the end of the tension support bar 4 pushes the uppermost cylindrical body 1 upward, and the tension support bar 4 provided on the bottomed cylindrical body 1a which is the lowermost part of the pan body 3 is provided. The ends push the bottomed cylindrical body 1a at the bottom, so that the cylindrical bodies 1 in the vertical relationship of the plurality of cylindrical bodies 1 forming the pan body 3 are separated from each other. Because it pushes, it tightly locks tightly without generating a gap between the lower end side inner surface of the cylindrical body 1 located on the upper side which becomes the sliding surface and the upper end side outer surface of the cylindrical body 1 located on the lower side, for example, Even when a liquid such as water is added, there is no fear that the liquid leaks from the sliding surface of each cylindrical body 1, and the liquid can be used with peace of mind.

  Further, since the bending of the upright tension support bar 4 is prevented by the slide lock mechanism 5 provided on the tension support bar 4, the tension support bar 4 of the pot in use is bent. The cylindrical body 1 that forms the pan body 3 is slide-degenerated, the pan body 3 is in a degenerate polymerization state, and there is no worry that the contents will spill out during cooking, and can be used with confidence. It becomes a stretchable pan with excellent properties.

  In addition, since the slide lock mechanism 5 is fitted or detached from the connecting portion 8 by automatic slide without any manual operation, the support rod body 4 is bent during use due to forgetting to apply the slide lock mechanism 5. Thus, the pan body 3 is degenerated, and it becomes an epoch-making telescopic pan with excellent practicality that does not cause the trouble of spilling the contents during cooking.

  Furthermore, even when the sliding surface wears down due to deterioration with time and the adhesion (sealability) is lowered, the length of the tension support bar 4 itself is extended by the tension adjusting portion 7 provided on the tension support bar 4. The tubular body 1 and the bottomed tubular body 1a forming the pan body 3 can be restored to each other in the direction away from each other, and can be easily adjusted to the expanded state similar to the initial state. 1 and the sliding surface of the bottomed cylindrical body 1a can always be kept firmly and firmly locked, and can be kept in a state where there is no fear of leakage from the seal portion 6 serving as the sliding surface. It becomes a typical telescopic pan.

  Furthermore, since this tension support bar body 4 can be removed from the pan body 3, it is possible to remove the tension support bar body 4 and disassemble the plurality of cylindrical bodies 1 and bottomed cylindrical bodies 1a apart. In addition, sliding surfaces that are difficult to clean in the assembled state can be cleaned cleanly, and a clean feeling can always be maintained.

  In addition, in this embodiment, not only the pan body 3 but also the handle portion 9 that protrudes from the pan body 3 is folded, so that the projecting portion is eliminated, and the bulk at the time of storage can be suppressed and the compact body can be stored. Moreover, since the folded handle portion 9 abuts against the bottom portion 2 of the pan body 3 in the compact storage state and prevents the pan body 3 from being extended, the pan body 3 does not stretch during carrying. In addition, even when the pan in the storage state is held, it is not necessary to hold the bottom 2 while holding the pan 2 by hand so that the pan body 3 does not slide and extend, so that the pan is very convenient to carry.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
