It is configured to be flush with the outer surfaces of the lid 3 and the cool box main body 2 when housed in the side portion of the main body 2. Further, shoulder belts 9 may be attached to both sides of the cool box main body 2 so as not to interfere with the hooks 10.

Hereinafter, the structures of the handle 5 and the hook 10 will be described in detail with reference to FIGS. The handle 5 is composed of a pair of legs 5a extending in parallel and a grip 5b perpendicular to these legs. As shown in FIG. 1B, the longitudinal direction of the cool box main body 2 is longer than that of the lid 3 by an amount corresponding to the substantial thickness of the leg 5a. A concave portion 2a is formed in the side surface portion so as to substantially correspond to the thickness of the leg portion 5a. A pair of holes are formed downward on the upper end surface 2b of the side surface of the cool box main body 2 defined by the recesses 2a, corresponding to the legs 5a, so as to accommodate the legs. ing. A long hole 5c extending in the vertical direction is formed in each leg 5a, and a shaft 6 provided on a side surface of the cool box main body 2 is engaged with this portion. As a result, as shown by the dotted line and the solid line in FIG. 1B, the handle 5 is slid in the up and down direction and rotated, so that the cool box 1 can be carried and towed.

The hook 10 is disposed in the recess 2a, is surrounded by the leg 5a and the grip 5b of the handle 5, and is engaged with a locking member attached to the lid 3. Then, the lid 3 is closed and fixed to the cool box main body 2. In this embodiment, as shown in FIG. 2, the locking member 20 is provided on the back surface of the lid 3 so as not to interfere with the grip 5b of the handle 5, and the shape of the hook 10 is changed. It is configured to be downsized.

[0012] As shown in FIG.
a mounting plate 11 attached to the side surface of the cool box main body 2 in FIG.
The operating piece 12 is supported by a supporting portion 11a formed through the shaft 11b and extends in parallel with the shaft 11b.
2 and a fastening frame plate 15 which is pivotally supported at both ends of a shaft 12a. An engagement projection 15a bent in a U-shape is formed on the tip side of the fastening frame plate 15, and the tip side of a locking member 20 attached to the back surface of the lid 3 and extending downward. U-shaped locking portion 20
a can be engaged. Thus, the locking member 20
Is extended downward from the back surface of the lid 3, so that the hook 10
As a result, the hook 10 does not protrude outward from the handle 5 in the recess 2a while being surrounded by the handle 5, and furthermore, does not interfere with the handle 5 at all. It is possible to arrange without doing.

On the back surface of the cover 3, the cover 3
When closed, a packing 30 is provided around the both sides so as to seal them and not to impair the cooling effect. In the embodiment shown in the drawings, a sufficient cooling effect is obtained.
Although the cool box main body 2 and the lid 3 are abutted in a step-like manner, and the packing is arranged in the lower part, the structure of the packing and the abutting relationship between the two can be variously modified.
For example, the two may be brought into contact with each other in a configuration as disclosed in Japanese Utility Model Application Laid-Open No. 507-171.

In the state shown in FIG. 2, if the operation piece 12 is manually operated and turned in the direction of the arrow, the shaft 12a
It rotates beyond the dead center position connecting the engagement position between the engagement protrusion 15a and the engagement portion 20a and the shaft 11b, and gradually raises the fastening frame plate 15 to move the engagement protrusion 15a and the engagement portion 20a. Release the engagement relationship. In this case, the fastening frame plate 1 is attached to the locking member 20 so that the fastening frame plate 15 does not contact the grip 5b of the handle 5.
An inclined portion 20b for guiding the outer side 5 is formed.
Then, when the engagement relationship between the engagement protrusion 15a and the locking portion 20a is released as shown by a dotted line, the lid 3 can be opened from the cool box main body 2.

As described above, the hook 10 is completely surrounded by the handle 5 and is arranged so as not to protrude outside. Therefore, the hook 10 is in a state protected by the handle 5, and other objects such as the shoulder belt 9 may be caught,
The contact is prevented, and the disengagement is prevented. In addition, since the locking member 20 is extended from the back surface of the lid 3 and the hook is engaged with this portion,
It is possible to reduce the size of the hook 10 and make it completely enclosed without protruding from the handle 5. In addition, with such a configuration, the operation of the hook 10 can be performed without causing any interference with the grip portion 5b of the handle.

Although the embodiments of the present invention have been described above, the present invention can be variously modified in addition to the above embodiments. For example, the shape of the handle and the operation thereof can be variously modified. For example, the handle may be formed in a square shape so as to rotate only. According to this structure, the locking member with which the hook is engaged can be attached to the side surface or the upper surface of the lid. Further, depending on the shape of the handle and the mounting position of the locking member, a concave portion may be formed in the grip portion of the handle so as not to hinder the operation of the hook.
