Description

The present invention relates to a cold storage box that can store fish and the like in a cold state.

Generally, in fishing, a cold storage box (cooler box) is known in which ice, fish, and the like are carried and the caught fish can be transported in a cold state.

Such a cold storage box is, for example, a heat insulating box having a box-shaped, for example, heat insulating structure that forms a storage space inside, and is rotatably supported with respect to the upper edge of the main body to close the upper opening of the main body. It has a lid having a structure.

Further, the lid body is generally provided with a rotatably lock lever that locks to the main body in a locked state and holds the closed state of the upper opening of the main body by the lid body (see, for example, Patent Document 1). .. That is, when the lock lever is locked to the main body by pushing down the lock lever with the upper opening of the main body closed by the lid, the upper opening of the main body is held in the closed state and the upper opening of the main body cannot be opened by the lid. On the other hand, when the lock lever is released from the locked state with respect to the main body by pulling up the lock lever, the lid can be rotated with respect to the main body to open the upper opening of the main body.

Japanese Unexamined Patent Publication No. 7-76357

By the way, in the structural form including the lock lever, in order to rotate the lid with respect to the main body to open the upper opening of the main body, the lock lever is engaged with the main body so as to pull up the lock lever by hand as described above. It is necessary to release the stopped state, but if you release the lock lever that was pulled up after releasing it, the lock lever may drop and get caught in the main body. If the lock lever is pulled up by hand and held without releasing the lock lever to open the lid, such a problem does not occur, but in some situations, the lock lever is released and then locked. In some cases, the lever is switched to the lid itself to open the lid, and in such a case, the lock lever may be lowered and caught on the main body, making it impossible to open the lid.

In particular, when trying to open the lid by operating the lock lever with one hand while doing some work, if the lock lever that was pulled up is lowered again and gets caught in the main body, the catch must be released. Subsequent opening operation of the lid becomes troublesome. In particular, when a plurality of lock levers are provided on one side of the main body, the phenomenon of the lock levers falling back after unlocking makes the subsequent opening operation of the lid more complicated, and the opening work with one hand is performed. Is extremely difficult.

The present invention has been made by paying attention to the above-mentioned problems, and provides a cold storage box that prevents the lock lever from falling down after unlocking and enables a smooth and easy opening operation of the lid. The purpose is.

In order to achieve the above object, the present invention has a box-shaped main body that forms a storage space inside, and a lid that is rotatably supported with respect to the upper edge of the main body and closes the upper opening of the main body. A cold storage box having a body and a lock lever rotatably provided on the lid and locked to the main body in a locked state to hold the upper opening of the main body closed by the lid. Further, the lock lever is provided with a holding portion that elastically locks the lock lever with respect to the lid body in the non-locked state in which the lock lever is released from the main body, and holds the unlocked state. The lever has a locking position that is locked to the main body in the locked state and a holding position that is held in the unlocked state by the holding portion, centering on the rotation axis of the lid with respect to the main body. It is characterized by rotating between.

According to the above configuration, in the unlocked state in which the lock lever is released from the main body, the lock lever can be elastically locked to the lid by the holding portion to maintain the unlocked state. It is possible to avoid a situation in which the lid cannot be opened due to the lock lever falling down after unlocking and being caught on the main body. Therefore, even if the lock lever is released and then the lock lever is switched to the lid itself to open the lid, or while doing some work, the lock lever is operated with one hand to open the lid. Even if it does, it can enable a smooth and easy opening operation of the lid. This is extremely useful, especially in the case where a plurality of lock levers are provided on one side of the main body, in that the opening work with one hand can be facilitated.

In the above configuration, it is preferable that the holding portion holds the lock lever in a state of being pulled up from the locked position with respect to the main body to hold the unlocked state. According to this, not only can it surely prevent the lock lever from being caught unexpectedly on the main body of the lock lever in the unlocked state, but also it is possible to visually grasp at a glance that the lock lever is in the unlocked state by the pulled-up lock lever. In addition, since the lock lever can be easily grasped when the lock lever is held and the lid is opened, a smooth opening operation of the lid can be realized.

Further, in the above configuration, the holding portion is composed of a convex portion provided on the lock lever and a locking portion provided on the lid body to engage and disengage the convex portion, or is provided on the lid body. It may be composed of a convex portion and a locking portion provided on the lock lever to engage and disengage the convex portion. As a result, the lock lever can be held in the unlocked state with a simple configuration.

According to the present invention, it is possible to obtain a cold storage box that prevents the lock lever from falling down after unlocking and enables a smooth and easy opening operation of the lid.

It has a concave locking groove 2e formed on the upper surface of the support portion 2c provided on the 2b to receive the rotating shaft 39, and the rotating shaft 39 is received and pivotally supported by the locking groove 2e. Thereby, the lid 4 can be rotated with respect to the main body 2 with the received shaft support side as the rotation center (the lid 4 can be opened and closed with respect to the main body 2 in a one-sided opening state).

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

Further, the lock lever 40 has a locking protrusion 40b at the tip of a thick portion 40A protruding inward from a lower portion thereof so that the lock lever 40 can be locked to the main body 2 in a locked state. The protrusion 40b is detachably locked to the locking recess 2d formed on the lower surface of the support portion 2c of the main body 2, whereby the lock lever 40 is locked to the main body 2 in a locked state, whereby the lid is locked. The closed state of the upper opening 2a of the main body 2 by the body 4 is maintained.

Further, in the cold storage box 1 of the present embodiment, the lock lever 40 is attached to the lid 4 in an unlocked state in which the lock lever 40 is released from the lock lever 40 with respect to the main body 2 (locking of the locking protrusion 40b with respect to the locking recess 2d). It is provided with a holding portion that is elastically locked to hold the unlocked state. In the present embodiment, such a holding portion includes a convex portion 40a provided on the thin-walled portion 40B of the lock lever 40 and a locking portion 4b provided on the lid 4 to engage and disengage the convex portion 40a. Consists of. In this case, the locking portion 4b is formed as a stepped locking step portion formed between the lower end edge 4a of the lid 4 and the inner closing surface 4c of the lid 4, and the convex portion 40a is locked. It is formed as a protrusion extending in a predetermined length along the left-right direction on the surface of the lock lever 40 which is located on the opposite side of the protrusion 40b and faces the outside.

Next, the operation of such a holding portion will be described with reference to FIG.
First, as shown in FIG. 4A, the locking protrusion 40b of the lock lever 40 is locked to the locking recess 2d of the support portion 2c of the main body 2, so that the lock lever 40 is engaged with respect to the main body 2. Locked in the locked state, whereby the closed state of the upper opening 2a of the main body 2 by the lid 4 is maintained (the state of (b) in FIG. 5), and the locked state of the lock lever 40 with respect to the main body 2 is held. When the lock lever 40 is pulled up by hand so as to release the lock lever 40, the locking protrusion 40b is disengaged from the locking recess 2d as shown in FIG. 4 (b). When the lock lever 40 is pulled up by a predetermined amount so as to rotate upward about the rotation shaft 39 as it is, the convex portion 40a faces the lower end edge 4a of the lid 4 as shown in FIG. 4 (c). Then, when the lock lever 40 is further rotated in that state, the convex portion 40a abuts on the lower end edge 4a as shown in FIG. 4D, and then the convex portion 40a is pushed down by the lower end edge 4a. As the thin-walled portion 40B elastically deforms, the convex portion 40a gets over the lower end edge 4a and enters the inner space between the main body 2 and the lid 4 as shown in FIG. 4 (e), and the locking portion 4b Elastically locks to. As a result, the lock lever 40 is held in a state of being pulled up (unlocked state) from the locked position with respect to the main body 2 (state of FIG. 5A). Therefore, the upper opening 2a can be opened by rotating the lid 4 with respect to the main body 2 without any trouble.

As described above, according to the present embodiment, the lock lever 40 is elastically attached to the lid 4 by the holding portion (4b, 40a) in the unlocked state in which the lock lever 40 is released from the main body 2. Since the lock lever 40 can be locked to and held in the unlocked state, it is possible to avoid a situation in which the lock lever 40 after unlocking falls and is caught by the main body 2 and the lid 4 cannot be opened. Therefore, even when the lock lever 40 is released and then the lock lever 40 is switched to the lid 4 itself to open the lid 4, or the lock lever 40 is operated with one hand while performing some work, the lid 40 is operated. Even when trying to open the body 4, a smooth and easy opening operation of the lid 4 can be enabled. This is extremely useful, in particular, in the case where a plurality of lock levers 40 are provided on one side of the main body 2 as in the present embodiment, the opening work with one hand can be facilitated.

Further, in the present embodiment, the lock lever 40 is held in the unlocked state by being held in a state of being pulled up from the locked position with respect to the main body 2, so that the main body 2 of the lock lever 40 in the non-locked state is held. Not only can it be surely prevented from being caught unexpectedly afterwards, but it is also possible to visually grasp at a glance that the lock lever 40 is in the unlocked state by the pulled-up lock lever 40, and the lock lever 40 is held to hold the lid 4 Since it is easy to grip the lock lever 40 when opening the lid 4, a smooth opening operation of the lid 4 can be realized.

Further, in the present embodiment, the holding portion is composed of a convex portion 40a provided on the lock lever 40 and a locking portion 4b provided on the lid 4 to engage and disengage the convex portion 40a. , The lock lever 40 can be held in the unlocked state with a simple configuration.

FIG. 6 shows a first modification of the holding portion. As shown in the figure, the holding portion according to this modification is a locking portion provided on the inner closing surface 4c of the lid 4 and the convex portion 4d provided on the lock lever 40 so as to be engaged and disengaged. It is composed of parts. The locking portion provided on the lock lever 40 may be a concave portion to which the convex portion 4d can be locked, but in this modification, the surface locking portion of the thin-walled portion 40B of the lock lever 40 that can be easily elastically deformed. It is formed by (a surface portion to which the convex portion 4d can be locked).

In the holding portion having such a configuration, the lock lever 40 is further pulled up about the rotation shaft 39 from the state of (a) of FIG. 6 (the state corresponding to (b) of FIG. 4) which is the unlocked state. As the thin-walled portion 40B (tip) enters the inner space between the main body 2 and the lid 4, the tip of the thin-walled portion 40B becomes a convex portion as shown in FIG. 6B. After hitting 4d, as shown in FIG. 6C, the thin-walled portion 40B is elastically deformed so as to be pushed down by the convex portion 4d, so that the tip of the thin-walled portion 40B gets over the convex portion 4d and is shown in FIG. As shown in (d), the thin portion 40B is held in a substantially horizontal state elastically locked to the convex portion 4d. Therefore, it is possible to obtain the same effect as that of the above-described embodiment. The convex portion 4d is formed by attaching a separate leaf spring 100 having the convex portion 4d to the inner closed surface 4c of the lid 4 by, for example, a screw 102, as shown in FIG. 6 (e).
