Then, the large and small projections (17) and (18) are arranged at predetermined intervals in the circumferential direction on the peripheral surfaces (14) and (15) of the second and third fulcrum members (2b) and (2c). The projections (17) of the second and third support legs (1b) (1c) are projected when they are respectively projected, and when the three support legs (1a) (1b) (1c) are spread in an equiangular state. Is provided at a position where it comes into contact with the side surface of the first supporting leg (1a), and the small protrusions (18) of the second and third supporting legs (1b) (1c) have three supporting legs (1a) (1b). ) (1c) is provided at a position where it abuts the protrusion (16) of the first support leg (1a) when it is expanded to an equiangular state, and the three support legs (1a) (1b) (1c) ) Is expanded to an equiangular state, the large protrusion (17) and the small protrusion (18) sandwich and lock the side surface of the first support leg (1a) and the protrusion (16). It is configured in.

[0008]

[Action]

 This device operates as follows, for example, as shown in FIGS. 1 to 6. That is, the foldable holder is mounted on the bottom surface of the portable gas cartridge as follows.

That is, when the support legs (1a), (1b), and (1c) are swung in the circumferential direction of the fulcrum members (2a), (2b), and (2c) to expand, the first support legs (1a) (16) over the small protrusions (18) of the second and third fulcrum members (2b) (2c), and the large protrusions of the second and third fulcrum members (2b) (2c). It is located between (17) and the small protrusion (18).

At this time, the large protrusions (17) of the second and third support legs (1b) and (1c) come into contact with the side surfaces of the first support leg (1a), respectively, and the second and third support legs (1a) and (1c) contact each other. The small protrusions (18) of the support legs (1b) (1c) abut the protrusions (16) of the first support legs (1b), respectively.

In this state, the side surface of the first support leg (1a) and the protrusion (16) are sandwiched by the large protrusions (17) and the small protrusions (18) of the respective support legs (1b) (1c). The three support legs (1a) (1b) (1c) are stopped and held in a state of being spread at equal angles (state of FIG. 1).

Then, the supporting legs (1a) (1b) (1c) are attached to the bottom of the portable gas cartridge (3) with the holding projections (6) of the supporting legs (1a) (1b) (1c). ) Is expanded, the gas cartridge (3) is held by the holding projections (6) and the foldable holder is attached to the bottom surface of the gas cartridge (3).

On the other hand, the supporting legs (1a) (1b) (1c) are attached to the fulcrum members (2a) (2b) from a state where the three supporting legs (1a) (1b) (1c) are spread at equal angles. By swinging in the circumferential direction of (2c), the protrusions (16) of the first support leg (1a) with respect to the small protrusions (18) of the second and third fulcrum members (2b) (2c).

[0014]

[Effect of device]

 The present invention has the following effects because it is configured and operates as described above. Since the support legs rotate around the axis of the fulcrum member and expand, the holding projections of the portable gas cartridge of each support leg also expand in an arc shape. In other words, the holding projections of the supporting legs can be spread along the peripheral edge of the bottom surface of the portable gas cartridge having a circular shape, and the bottom surface of the gas cartridge can be held by the holding projections. Therefore, the foldable holder can be easily attached to the bottom surface of the portable gas cartridge.

Further, since the support legs rotate around the axis of the fulcrum member and are folded, in the folded state, the three support legs are arranged so as to be close to each other. In other words, the supporting legs do not line up diagonally when folded like a conventional holder in which the supporting legs are connected at a position closer to the tip side of the supporting legs. Therefore, the length of the holder in the folded state can be made shorter than that of the conventional holder by the amount that the supporting legs do not line up obliquely when folded. As a result, the holder when folded is compact, and the storage space for storing the foldable holder in a backpack can be reduced.

The second small protrusions are provided on the peripheral surfaces of the second and third fulcrum members, respectively, and when the supporting legs are folded, the protrusions of the first supporting legs are the second small protrusions. When the support leg is configured to be sandwiched between the protrusion and the support leg provided with the second small protrusion, even if the support leg expands, the protrusion of the first support leg and the second small protrusion are Are abutted against each other, or the support legs are abutted against each other to restrict the expansion of the support legs. As a result, when the foldable holder is stored in the backpack, it is possible to prevent the support legs from expanding inside the backpack and making it difficult to take out the backpack from the backpack.

Further, when the grounding portion of the first support leg is fitted into the notches of the second and third support legs when the support leg is folded, the support leg is The width of the foldable holder can be made compact, and the storage space for storing the holder in a backpack can be made smaller.

By tightening the screw (10) from the lower surface of the support shaft (7) into the screw part (7a) of the support shaft (7), the three-stage support member (2a) (2b) (2c) Are connected in an overlapping state (state of FIG. 2).

The diameter of the head of the screw (10) is larger than the diameter of the through hole (8) of the lowermost fulcrum member (2c), and the screw (10) is attached to the shaft ( The fulcrum member (2a) at the middle stage and the fulcrum member (2c) at the bottom stage are prevented from falling off from the fulcrum shaft (7) while being tightened in 7).

In the continuous base end face (13) of the middle stage fulcrum member (2a) and the first support leg (1a), the continuous base end face (13) above the middle stage fulcrum member (2a) is The continuous base end surface (13) facing the peripheral surface (14) of the uppermost fulcrum member (2b) and lower than the middle fulcrum member (2a) is the lowermost fulcrum member (2c). Face the circumference (15) of. A protrusion (16) extending in the up-down direction is provided on the continuous base end face (13).

On the other hand, on the peripheral surfaces (14) and (15) of the uppermost and lowermost fulcrum members (2b) and (2c), as shown in FIGS. A first small protrusion (18) and a second small protrusion (19) are provided at predetermined intervals in the circumferential direction.

The large protrusions (17) of the uppermost and lowermost fulcrum members (2b) (2c) are used when the three support legs (1a) (1b) (1c) are spread at equal angles. And is provided at a position where it abuts the side surface of the first support leg (1a). Further, the first small protrusions (18) of the fulcrum members (2b) (2c) at the uppermost stage and the lowermost stage are formed when the supporting legs (1a) (1b) (1c) are expanded in an equiangular state. It is provided at a position where it abuts on the projection (16) of the first support leg (1a).

When the support legs (1a) (1b) (1c) are spread in an equiangular state, the large protrusions (17) and the first small protrusions (18) cause the first protrusions (18) to move. The side surface of the support leg (1a) of No. 1 and the protrusion (16) are sandwiched and locked (state shown in FIGS. 3 and 4). That is, the supporting legs (1a) (1b) (1c) are held in a state of being spread at an equal angle.

In addition, by swinging the support legs (1a) (1b) (1c) from the state where the support legs (1a) (1b) (1c) are expanded, the first support legs (1a) The projection (16) of the vehicle rides over the first small projection (18) and is disengaged from between the large projection (17) and the first small projection (18), and the support legs (1a) (1b) ) (1c) can be folded.

On the other hand, the second small protrusions (19) of the uppermost and lowermost fulcrum members (2a) (2c) are arranged so that the three supporting legs (1a) (1b) (1c) are close to each other. The first support leg (1a) is provided with the second small protrusion (19) and the second small protrusion (19) when the first support leg (1a) has the protrusion (16). It is provided at a position sandwiched between 1c) (see FIGS. 5 and 6).

As a result, even if the support legs (1a) (1b) (1c) try to expand from the folded state, the protrusion (16) of the first support leg (1a) and the second small protrusion ( 19) or the supporting legs (1a) (1b) (1c) contact each other, whereby the expansion of the support legs (1a) (1b) (1c) is restricted.

In addition, by swinging the support legs (1a) (1b) (1c) from the state where the support legs (1a) (1b) (1c) are folded, the first support legs (1a) The protrusion (16) is the second small protrusion (1
9), the supporting legs (1a), (1b) and (1c) can swing freely.

Next, a method of using the foldable holder will be described. First, the mounting of the foldable holder on the portable gas cartridge (3) will be described.

Further, since the supporting legs (1a) (1b) (1c) are expanded to an equiangular state, the hook portion (6) of each supporting leg (1a) (1b) (1c) has a circular shape. The hook (6) holds the bottom surface of the gas cartridge (3) extending along the periphery of the bottom surface of the cartridge (3).

On the other hand, when the support legs (1a) (1b) (1c) are folded from the expanded state, the protrusions (16) of the first support legs (1a) cause the uppermost and lowermost fulcrum members (2b). ) (2c) over the first small protrusion (18), the protrusion (16) is disengaged from between the large protrusion (17) and the first small protrusion (18), and the support leg ( The bottom surface of the gas cartridge (3) can be removed from the hook portions (6) of the supporting legs (1a), (1b), (1c) by folding 1a, 1b, 1c.

Further, since the supporting legs (1a) (1b) (1c) are folded, the protrusions (16) of the first supporting legs (1a) are fulcrum members (2b) at the uppermost stage and the lowermost stage. Between the second small protrusion (19) and the supporting leg (1b) (1c) provided with the second small protrusion (19) by overcoming the second small protrusion (19) of (2c). The support legs (1a) (1b) (1c) are restricted from expanding by being sandwiched between the support legs (1a) (1b) (1c). The folded state is retained.

That is, even if the foldable holder is housed in a backpack or the like with the support legs (1a) (1b) (1c) folded, the support legs (1a) (1b) (1c) are not It will be difficult to spread.

In this way, since the support legs (1a) (1b) (1c) spread around the fulcrum members (2a) (2b) (2c), the support legs (1a) (1b) (1c) The hook portion (6) also expands in an arc shape. That is, the hook portion (6) of each of the supporting legs (1a) (1b) (1c) is spread along the peripheral edge of the bottom surface of the circular portable gas cartridge (3) to expand the gas cartridge (3). The bottom surface can be held by the hook portion (6). Therefore, the foldable holder can be easily attached to the bottom surface of the gas cartridge (3).

Further, since the support legs (1a), (1b) and (1c) are rotated around the axis of the fulcrum members (2a), (2b) and (2c) and folded, three support legs are provided in the folded state. The legs (1a) (1b) (1c) are lined up close to each other. That is, the support legs do not line up diagonally when folded like a conventional holder in which the support legs are connected at a position closer to the tip end side of the support legs. Therefore, the length of the holder in the folded state can be made shorter than that of the conventional holder by the amount that the supporting legs do not line up diagonally when folded. As a result, the holder when folded is compact, and the storage space for storing the foldable holder in a backpack or the like can be reduced.

The above embodiment can be modified as follows. That is, in the above embodiment, the projection (16) is provided on the continuous base end surface (13) of the first support leg (1a), but the uppermost fulcrum member (2b) and the second support leg (1b) are provided. ), Or the projection (16) may be provided on the base end face connecting the lowermost fulcrum member (2c) and the third support leg (1c). In this case, the fulcrum member (2a) in the middle stage is provided with the large protrusion (17), the first small protrusion (18) and the second small protrusion (19).
