Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a portable cold storage container used for fishing or other leisure purposes.

(Prior Art and Problems) Conventionally, portable cold storage containers used for fishing and other leisure activities have a lid connected to the container by a hinge so that it can be opened and closed. By the way, in the case of cold containers for fishing, since the fish etc. that have been caught are directly stored,
The inside of the container is heavily soiled, so cleaning such as washing with water is always recommended after use. However, since the lid is integrally connected to the container via a hinge, it is difficult to clean the cold storage container and the cleaning work becomes complicated.

Therefore, recently, a detachable hinge is used to connect the container and the lid so that they can be opened and closed, and when cleaning the container, the hinge shaft of the hinge is pulled out and the hinge members are separated from each other, thereby separating the container and the lid. There is something like this.

However, in the case of a container with a separable hinge fixed to it as described above, the hinge shaft is completely separated from the hinge member, so not only is there a risk of losing the butterfly shaft, but also the two hinge members are mutually connected. There is a risk of damage if the butterfly shaft inserted across the shaft accidentally falls out.

(Technical problem to be solved by the invention) The technical problem to be solved by the invention is that even if the hinge that connects the container and the lid so that they can be opened and closed is separated, the container and the lid cannot be separated. To provide a container that does not cause the shaft to be lost or fall out.

(Technical means for solving the technical problem) The technical means taken by the present invention to solve the above problem is to install a hinge member having a joint on the side edge of the container and the lid so that the joints are aligned with each other. The butterfly shaft is fitted into the connecting portion of the two members so that it can be inserted and removed, and a finger hook is bent at one end, and a guide rod is connected to the finger hook. is provided protruding parallel to the butterfly shaft, and a locking portion is formed at the tip of the guide rod to fit into a locking groove recessed in the container or lid body facing the hinge member.

(Function) The container and the hinge member fixed to the lid are connected by a butterfly shaft, so that the lid opens and closes around the butterfly shaft, and the lid is separated by pulling the butterfly shaft outward by the finger hook. Accordingly, the latching part formed at the tip of the guide rod moves in the latching groove recessed on the container or lid side, and the latching part abuts and engages with the end of the latching groove. The shaft is prevented from coming off, the hinge member is disconnected, and the lid can be separated. The butterfly shaft is prevented from falling off by retaining the guide rod between the hinge member and a retaining groove formed in the container or the lid.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. A portable cold storage container A includes a container 1, a lid 2, a hinge 3 that connects the lid 2 to the container 1 in an openable and closable manner, and Container 1 and lid 2 on the opposite side of hinge 3
It consists of a hook (not shown) that engages and disengages the edge of the handle.

The container 1 and the lid 2 are formed with a heat insulating structure in which a heat insulating material is filled between the inner and outer frames in order to maintain the cold insulation function, and hinges 3 are installed at intervals on the side edges of the container 1 and the lid 2. Two are installed.

The hinge 3 is composed of a first hinge member 4 attached to the container 1 side, a second hinge member 5 attached to the lid 2 side, and a hinge shaft 6 connecting both hinge members 4 and 5. 4 and the second hinge member 5 are formed of synthetic resin or metal material into a flat plate shape, and a butterfly shaft 6 is inserted into both sides of one side edge of the first hinge member 4 and the center of one side edge of the second hinge member 5. A connecting portion 8 having a through hole 8a formed therein and a connecting portion 9 having a through hole 9a formed therein are integrally formed.

Therefore, the connecting portion 9 of the second hinge member 5 is fitted between the left and right connecting portions 8 of the first hinge member 4 so that they are aligned in a straight line, and the butterfly By inserting the shaft 6, both hinge members 4 and 5 are rotatably connected.

The butterfly shaft 6 is connected to the connecting portions 8 and 9 of both hinge members 4 and 5.
The shaft rod has a diameter to be inserted into the through holes 8a, 9a drilled in The finger rest 10 is extended and integrally bent, and a guide rod 11 is provided at the open end of the finger rest 10 to protrude in parallel in the same direction as the protruding direction of the butterfly shaft 6.
The tip of the guide rod 11 is bent at a right angle toward the container 1 to form a hook 12.

The above-mentioned latching portion 12 is a latching groove 13 recessed in the container 1.
The butterfly shaft 6 is prevented from coming off by being fitted into the retaining groove 13 and engaging with the terminal end of the retaining groove 13.

Furthermore, the length of the latching groove 13 is such that it ensures a stroke for the hinge shaft 6 to move the first hinge member 4 and the second hinge member 5 from the connected state to the separable position, and even if it is made as long as possible, the first hinge The length should be within the width of the member 4.

In the embodiment described above, the latching groove 13 is provided on the container 1 side, but it is of course possible to provide the latching groove 13 on the lid 2 side. In that case, the hinge members 4 and 5 are attached in the opposite direction, and the first hinge member 4 having the bifurcated connecting portion 8 is attached to the lid 2 side.

(Effects of the invention) Since the portable cold storage container of the present invention is constructed as described in detail above, by hooking a finger on the finger hook formed at the side end of the butterfly shaft and pulling it outward, the container or lid is recessed. When the latching part at the tip of the guide rod is brought into contact with the provided latching groove, the tip of the butterfly shaft moves to a position where the hinge member fixed to the lid body can be separated, and the lid body is separated from the container. Become free. This makes it possible to easily clean the inside of the container.

In addition, the butterfly shaft inserted through the hinge member on the container or lid side is prevented from moving outward because the latch portion at the tip of the guide rod that is integrated with the butterfly shaft is engaged with the end of the latch groove. Therefore, it is possible to reliably prevent the butterfly shaft from falling off and being lost, and the lid body can be reliably assembled and connected. Furthermore, even if the butterfly shaft moves due to vibration while the lid is attached, the guide rod with the hook part will be placed between the hinge member and the container or the lid. Since it is held in place, it can be completely prevented from falling off.
