Patent Document 1: Japanese Patent Application Laid-Open No. 7-76357

SUMMARY OF THE INVENTION

However, in the configuration with the lock lever, in order to rotate the cover relative to the main body and open the upper opening of the main body, it is necessary to lift the lock lever by hand to release the locked state of the lock lever to the main body as described above. However, if the hand leaves the lifted lock lever after the release, the lowered lock lever may be hooked on the main body. This problem does not occur if the cover is opened while holding the lock lever without leaving the lock lever in the state where the hand continues to lift the lock lever. In this case, the lid body is opened by changing the grip of the lid body itself from the lock lever. In such a case, there is a possibility that the lowered lock lever is hooked on the main body and the lid body cannot be opened.

In particular, when you want to open the cover by operating the lock lever with one hand while performing some work, if the lock lever that was finally lifted falls down again and is hooked on the main body, the hook has to be released, and the cover body after that opening operation becomes troublesome. In particular, when a plurality of lock levers are provided on one side of the main body, the phenomenon that the lock lever is lowered and reset after the lock is released makes the subsequent opening operation of the cover more complicated, and the opening operation with one hand becomes extremely difficult. difficulty.

The present invention has been made in view of the above-mentioned problems, and the technical problem to be solved is to provide a cold-insulation box which prevents the lock lever from falling after the lock is released, and enables a smooth and simple opening operation of the cover body.

In order to achieve the purpose, the present invention is a cold insulation box, which has: a box-shaped body, which forms a receiving space inside; a cover body, which is rotatably supported on the upper edge of the body to close the upper opening of the body; and a locking lever, which is rotatably provided on the cover body, and is locked to the body in a locked state to maintain the closed state of the cover body to the upper opening of the body, and is characterized in that it has a holding part, which can be released when it is released. In a non-locked state in which the locking lever is locked to the main body, the locking lever is elastically locked and held to the cover body.

According to the above configuration, in the unlocked state in which the locking of the locking lever to the main body is released, the locking lever can be elastically locked and held to the cover body by the holding portion, so that the locking lever after the unlocking can be prevented from being dropped and locked. A situation where the lid cannot be opened due to hanging on the main body. Therefore, even when the lid body is opened by changing the grip of the lid body from the lock lever after the lock lever is released, or when the lid body is opened by operating the lock lever with one hand while performing a certain work, smooth operation can be performed. And the opening operation of the cover is simple. This is particularly useful in that the opening operation can be easily performed with one hand when a plurality of lock levers are provided on one side of the main body.

Moreover, in the said structure, it is preferable that the holding|maintenance part hold|maintains in the state which raised the lock lever from the locking position with respect to the main body. According to this, it is possible not only to reliably prevent the lock lever from being unpredictably hooked to the main body afterward in the unlocked state, but also to grasp the unlocked state at a glance when the lock lever is lifted up, and to keep the locked state. When the lid body is opened by using the lever, the lock lever can be easily grasped, so that a smooth opening operation of the lid body can be realized.

In addition, in the above-mentioned configuration, the holding portion is constituted by a convex portion provided on the lock lever and a locking portion provided on the cover body to be detachably engaged with the convex portion, or may be formed by a convex portion provided on the cover body. and a locking portion provided on the locking lever and the convex portion is detachably locked. Thereby, the holding of the lock lever in the unlocked state can be realized with a simple structure.

ADVANTAGE OF THE INVENTION According to this invention, it is possible to obtain a cold-insulation box which can prevent the lock lever from falling after the lock is released, and can perform a smooth and simple opening operation of the lid body.

The cover body 4 is generally in the shape of a flat plate so as to close the upper opening 2a of the main body 2 .

In particular, in the cooling box 1 of the present embodiment, the lid body 4 is rotatably and detachably supported on both upper edge portions 2b (in this embodiment, the upper edge portions of the longer side walls 2B) that are opposite to each other on the main body 2 . 2b), a so-called double-open structure. Of course, the cover body 4 can also be rotatably supported on only one of the opposite upper edge portions 2b of the main body 2, which is a so-called single-opening structure.

In addition, the cold insulation box 1 of the present embodiment has a trolley case transport structure that can be transported by rotating the wheels 50 attached to the bottom of the main body 2 . These wheels 50 are rotatably supported on both sides of a support table 60 formed at the bottom of one side of the main body 2 (in this embodiment, the bottom of one long side wall 2B). In addition, the holder mounting parts 60a and 60a are attached to the left and right sides of the support base 60, and the draw rod holders 70 and 70 for erecting the draw rod can be detachably attached to the holder mounting parts 60a and 60a. FIG. 1 shows a state in which the tie rod holders 70 and 70 are not attached to the cage mounting parts 60a and 60a. On the other hand, FIG. 2 shows that the tie rod holders 70 and 70 are attached to the cage attaching parts 60a and 60a. 70 state. In addition, the support table 60 is also provided with a handle mounting portion 60b to which a retractable trolley handle 80 can be mounted. As shown in FIG. 2 , the trolley case handle 80 is located in the approximate center of the long side wall 2B in a state of being attached to the handle attachment portion 60b, so it is provided on the cover body 4 on the left and right sides in order to avoid the trolley case handle 80 . There are two lock levers 40 , which will be described later, locked to the main body 2 in a locked state.

In addition, the cold insulation box 1 is also provided with a handle for carrying and transporting the cold insulation box 1 between the opposite upper edge portions 2b of the main body 2 (the upper edge portion 2b of the short side wall 2A in this embodiment). 85 (refer to Fig.3 (a), (c)), the handle 85 is provided so that rotation is possible.

In addition, as clearly shown in FIGS. 3( b ) and ( d ), in the present embodiment, the support structure for rotatably supporting the cover body 4 to the main body 2 has a rotating shaft 39 on the peripheral portion of the cover body 4 , interposed The peripheral edge portion of the portion of the lid body 4 fitted to the upper edge portion 2b of the longer side wall 2B of the main body 2 from above is supported by the bracket 38; and the recessed locking groove 2e is formed in the main body The upper surface of the support portion 2c of the upper edge portion 2b of the longer side wall 2B of the 2 is used to receive the rotating shaft 39, and the rotating shaft 39 is received and supported by the locking groove 2e, so the received shaft can be supported by the rotating shaft 39. The support side is the center of rotation, and the lid body 4 is rotated relative to the main body 2 (the lid body 4 is opened and closed in a single-open state relative to the main body 2).

In addition, the cooling box 1 rotatably includes a lock lever 40 on the lid 4 , which is locked to the body 2 in a locked state to keep the lid 4 closed to the upper opening 2 a of the body 2 . Specifically, the lock lever 40 is rotatably supported by the bracket 38 (the rotation shaft 39 ) about the rotation shaft 39 . That is, in this embodiment, the rotating shaft 39 serves as both a rotating shaft for rotating the lid body 4 with respect to the main body 2 and a rotating shaft for rotating the lock lever 40 . In addition, in this embodiment, two such support structures and lock levers 40 are provided on the upper edge portions 2b of the long side walls 2B on both sides of the cooling box 1 (on the left and right sides of each side wall 2B (the main body). One side of 2) 2).

In addition, the locking lever 40 has a locking protrusion 40b at the tip end of the thick-walled portion 40A protruding inward from the lower part thereof so as to be locked to the main body 2 in a locked state, and the locking protrusion 40b is detachably locked by the locking protrusion 40b. The locking lever 40 is locked to the main body 2 in a locked state because of the locking recess 2d formed on the lower surface of the support portion 2c of the main body 2, thereby maintaining the closed state of the upper opening 2a of the main body 2 by the cover 4.

In addition, the cooling box 1 of the present embodiment includes a holding portion that elastically holds the main body 2 in an unlocked state (the locking of the locking protrusion 40b of the locking recess 2d) by the locking lever 40. The lock lever 40 is locked and held by the cover body 4 . In the present embodiment, such a holding portion is constituted by a convex portion 40a provided on the thin portion 40B of the lock lever 40 and a locking portion 4b provided on the lid body 4 and the convex portion 40a is detachably engaged with. At this time, the locking portion 4b is formed as a stepped locking step portion formed between the lower end edge 4a of the cover body 4 and the inner closing surface 4c of the cover body 4, and the convex portion 40a is formed as the opposite side of the locking protrusion 40b. A protrusion extending with a predetermined length in the left-right direction is formed on the surface of the lock lever 40 facing outward.

Next, the action of such a holding portion will be described with reference to FIG. 4 .

First, as shown in FIG. 4( a ), since the locking protrusion 40 b of the locking lever 40 is locked to the locking recess 2 d of the supporting portion 2 c of the main body 2 , the locking lever 40 is locked to the main body 2 in a locked state, thereby , if the locking lever 40 is lifted by hand from the state in which the lid body 4 is closed to the upper opening 2a of the main body 2 (the state in FIG. 5(b)) to release the locking state of the locking lever 40 to the main body 2, the As shown in FIG.4(b), the latching protrusion 40b is disengaged from the latching recessed part 2d. In this state, when the lock lever 40 is lifted by a predetermined amount so as to be rotated upward about the rotating shaft 39, as shown in FIG. On the other hand, if the lock lever 40 is further rotated in this state, as shown in FIG. 4( d ), after the convex portion 40a pushes against the lower end edge 4a, the thin portion 40B is formed as the convex portion 40a is pressed by the lower end edge 4a. Due to elastic deformation, as shown in FIG. 4( e ), the convex portion 40a goes beyond the lower end edge 4a and enters the inner space between the main body 2 and the cover body 4, and is elastically locked to the locking portion 4b. Thereby, the lock lever 40 is held in the state (unlocked state) raised from the latching position with respect to the main body 2 (state of FIG.5(a)). Therefore, the lid body 4 can be rotated relative to the main body 2 to open the upper opening 2a without being hindered.

As described above, according to the present embodiment, in the unlocked state in which the locking of the locking lever 40 to the main body 2 is released, the locking lever 40 can be elastically locked and held to the lid body 4 by the holding portions 4b and 40a. It is possible to avoid a situation where the lock lever 40 after the unlocking is dropped and is hooked on the main body 2 and the lid body 4 cannot be opened. Therefore, even when the cover body 4 is opened by changing the grip of the cover body 4 itself from the lock lever 40 after the lock lever 40 is released, or the cover body 4 is opened by operating the lock lever 40 with one hand while performing some work. At the time, a smooth and simple opening operation of the lid body 4 can be performed. This is particularly useful in that the opening operation can be easily performed with one hand when a plurality of lock levers 40 are provided on one side of the main body 2 as in the present embodiment.

In addition, in the present embodiment, since the lock lever 40 is held in a state of being lifted from the locking position with respect to the main body 2 and thus maintained in an unlocked state, it is not only possible to reliably prevent the lock lever 40 from being locked to the main body 2 in the unlocked state. In addition, when the lock lever 40 is held and the cover body 4 is opened, it is easy to grasp the lock lever 40. Since the lock lever 40 is held, a smooth opening operation of the lid body 4 can be realized.

In addition, in the present embodiment, since the holding portion is constituted by the convex portion 40a provided on the lock lever 40 and the locking portion 4b provided on the cover 4 and the convex portion 40a is detachably locked, it is possible to use a simple structure. The holding of the locking lever 40 in the unlocked state is achieved.

FIG. 6 shows a first modification of the holding portion. As shown in the figure, the holding part according to this modification is constituted by a convex part 4d provided on the inner closing surface 4c of the cover body 4 and a locking part provided on the lock lever 40 and the convex part 4d is detachably engaged with the convex part 4d. . The locking portion provided in the lock lever 40 may be a concave portion to which the convex portion 4d can be locked. The surface portion where the portion 4d can be locked) is formed.

In the holding portion configured in this way, when the lock lever 40 is further rotated from the unlocked state, that is, the state in FIG. The wall portion 40B (the top end) enters the inner space between the main body 2 and the cover body 4, and the top end of the thin-walled portion 40B abuts against the convex portion 4d as shown in FIG. 6(b), and then as shown in FIG. 6(c) As shown in Fig. 6(d), the thin portion 40B is elastically deformed so that the thin portion 40B is pressed down by the convex portion 4d, and the tip of the thin portion 40B goes over the convex portion 4d, as shown in Fig. 6(d). It is held in a substantially horizontal state locked to the convex portion 4d. Therefore, the same functions and effects as those of the aforementioned embodiment can be obtained. Furthermore, as shown in FIG. 6( e ), the convex portion 4d may be formed by attaching, for example, a separate leaf spring 100 having the convex portion 4d to the inner closing surface 4c of the lid body 4 with bolts 102 .

FIG. 7 shows a second modification of the holding portion. As shown in the figure, the holding portion according to this modification has a convex portion provided on the thin-walled portion 40B of the lock lever 40 similarly to the aforementioned embodiment, but the convex portion 40 a ′ is formed integrally with the lock lever 40 . Alternatively, the leaf spring may be formed as a separate body, and the inner closing surface 4c of the lid body 4, which is the locking portion, is elastically locked at the inner side of the center O of the rotating shaft 39 . In this way, even if the protrusion 40 a ′ is not locked to the locking step 4 b as in the above-described embodiment, as long as it is located further inward than the center O of the rotating shaft 39 , the protrusion 40 a ′ is simply elastically locked. When the inner sealing surface 4c of the cover body 4 is press-contacted, the unlocked state can be stably maintained.

As mentioned above, although one Embodiment of this invention was described with reference to drawings, this invention is not limited to the said embodiment, Various deformation|transformation can be carried out in the range which does not deviate from the summary. For example, the shape and the like of the cooling box can be arbitrarily set according to the application, and the cooling box of the present invention is not limited to fishing. In addition, the number of lock levers, the configuration of the holding portion, and the like can be arbitrarily set.
