Further, as shown in FIG. 9B, in this embodiment, the receiving portion 34f is a notch formed at the edge of the end of the connecting portion 34, but it can also be implemented as a through hole.

  Further, as shown in FIGS. 9 (D) and 9 (E), the receiving bar portion 3 includes the folding-type connecting portion 34 (34x) shown in FIG. 8 and the split-type connecting portion 34 (34y shown in FIG. 9A). ) Can also be implemented. That is, as shown in FIG. 9 (D), in the receiving bar portion 3 that has a rectangular shape in plan view, the connection portions 34 and 34 that are located on the opposite first sides are foldable connection portions 34x and 34x, The connection parts 34 and 34 located in each of the other pair of opposing sides can be implemented as split connection parts 34y and 34y. Further, the receiving bar portion 3 using the connecting portion 34 that does not include the tank holding member 34d can also be implemented with a separate connecting portion (FIG. 4) and a folding connecting portion (FIG. 7).

In the above embodiment, the restraint mechanism is provided on the support column 21 and restrains the support column 21 from contracting. However, the restraint mechanism is not limited to this embodiment. Even those that are taken can be implemented.
Another example of the restraining mechanism will be described.
The upper and lower coupling portions n1 and n2 are formed of a known material such as plastic that is deformed by receiving force and returns to its original shape when no force is received. In the receiving portion n12, a narrow narrow portion (not shown) is provided at a position where the rotating link member 24 passes immediately before the bellows portion 22 is fully extended. deep. Immediately after the end portion of the link member 24 rotating in the direction of extending the bellows forcibly pushes the narrow portion and passes through the narrow portion, a regulating portion that defines the range of rotation of the link member 24 included in the receiving portion n12 It is assumed that the link member 24 comes into contact with (not shown), the narrow portion after passing through the link member 24 returns the width to the original state, and the link member 24 is not returned, and the restricting portion causes the link member to 24 is further rotated to make it impossible to open the bellows. By such a forced fitting of the link member 24 to the receiving portion n12, the bellows portion 22 can be restrained from extending further in the lateral direction after the tank 1 is opened.
This restraining mechanism restrains the bellows part 22 from further extending after the tank 1 is opened, and also restrains the bellows part 22 from contracting unexpectedly once the tank 1 is opened. Although the bellows part 22 is not easily shrunk after the water is stored in the tank 1, the bellows part 22 is unexpectedly shrunk before the water is stored by forming the restraining mechanism as described above, and the smooth operation of installing the water tank is performed. Can be prevented.
Furthermore, the crosspiece member 29 may be implemented as a function of a restraining mechanism.

A method similar to the above can also be adopted when the bellows portion 22 shown in FIG. 1D is contracted and the frame body 2 is fixed in a folded state. That is, in the receiving portion n12, the link member 24 that rotates in the opposite direction, that is, the reverse link member 24 passes through the position immediately before the bellows portion 22 is fully retracted. A portion (not shown) is provided. Immediately after the end of the link member 24 that reverses in the direction of contraction of the bellows forcibly widens the sub-narrow part and passes through the sub-narrow part, the range of the link member 24 provided in the receiving part n12 is defined. It is assumed that the link member 24 comes into contact with the sub-regulator (not shown), the sub-narrow portion after the passage of the link member 24 returns the width to the original state, and the link member 24 is not returned. The restricting portion reverses the link member 24 so that the bellows cannot be closed. By such a forced fitting of the link member 24 to the receiving portion n12, the contracted state of the bellows portion 22 can be maintained. The method of constraining the bellows portion 22 to the contracted state can also be implemented in the water tank shown in FIG.
As a restraining mechanism for restraining the bellows portion 22 from extending in the lateral direction after the tank 1 is opened, a method other than the above can be adopted. For example, the bellows portion 22 is provided in the receiving portion 12. In the fully extended state, a fixing means such as a separate pin may be attached to the receiving portion 12 and the direction of the link member 24 may be fixed. The method of fixing the length of the contracted bellows portion 22 can also be implemented by using a separate fixing means as described above. However, in a state where the bellows portion 22 is contracted, the bellows portion 22 may be prevented from being opened by another method such as binding with a belt.
