[Industrial application]

 The present invention relates to a lid locking mechanism for a warm / cold box for carrying, which is used for carrying foods, beverages, etc. in a drive, a picnic or the like.

[0002]

[Problems to be solved by conventional techniques and devices]

 A conventional portable warm / cold box is called a cooler box, which consists of a box-shaped main body and a lid that covers this main body.The main body and the lid both have a double structure and are filled with heat insulating material. Become.

By the way, in the portable heat insulation box, it is necessary to cover the lid when storing and taking out articles from the body, and firmly attach the lid to the body during transportation. .. For this reason, the portable warm / cold box is equipped with a fastening mechanism for the lid and main body.

A conventional fastening mechanism for a lid and a main body of a portable warm / cool box is a so-called patch-in lock, which has a structure in which the entire structure is exposed to the outside. However, if it is exposed to the outside, the projecting part becomes an obstacle when carrying it, and it is likely to be damaged by collision with other objects, etc., and it is inferior in design. Moreover, if the fastening mechanism is not built into the main body, the structure becomes complicated and the manufacturing becomes complicated. Therefore, the present invention proposes a new fastening structure for the main body and lid of the portable warm / cool box which is built in the main body and is easy to manufacture.

[0005]

[Means for Solving the Problems]

 The present invention is a portable heat insulation box that comprises a lid body and a main body, and has a locking mechanism that locks the lid body to the main body, and at least the main body is a double container body with a heat insulation function. In the upper edge of the main body, an opening having an upper portion and a front portion opened is formed at a portion where a hooking mechanism is formed, and a leg mounting portion which communicates with the lower portion of the opening and has a shaft hole at a side surface is formed. On the other hand, a hook portion is formed at the position where the lid mechanism is hooked, and the operating portion corresponding to the opening described above, the cover body fitting portion provided on the back surface of the operating portion, and the above-mentioned operating portion provided above the operating portion. A horizontal plate portion is formed by forming a hook main body having a hook portion corresponding to the hook portion and a leg portion provided with a shaft portion corresponding to the leg attachment portion below the operating portion and inserted into the shaft hole. And the horizontal plate part of the cover body consisting of the vertical plate part hung vertically on the edge of the horizontal plate part is attached to the cover body fitting part of the latching main body. Along with this, there is provided a hooking mechanism which is provided between the back surface of the operating part and the vertical plate part of the cover body and is attached to the opening part of the main body and the leg mounting part. ..

[0006]

[Action]

 When the hook part of the lid and the hook part of the hook body are in the hooked state, the body and the lid are fixed, and the operating part of the hook body is pressed with a finger or the like to resist the urging force of the spring. When the latch main body is rotated around the shaft and moved to the back, the hooked state of the hook part of the lid and the hook part of the latch body is released, and the cover can be opened. Become.

【Example】

 Next, an embodiment of the present invention will be described. The portable warm / cold box according to the present invention comprises a main body A and a lid B, both of which have a double structure on the peripheral surface and the like and are filled with an appropriate heat insulating material so as to have a warm and cool function. A food storage unit 01 and a pot unit (not shown) are formed at the same time, and a portable band 02 is attached, and the lid B is capped on the main body A to store the food storage unit 01. It is designed to exhibit the function of keeping warm and cold, such as being connected to the main body A by the hinge portion 03 so that it can be opened and closed and provided with an appropriate hooking mechanism between the two.

The latching mechanism is composed of a latching member including a latching main body 1, a cover body 2 and a spring 3, and a predetermined shape of a main body A and a lid B corresponding to the latching member. The latching body 1 has a box-shaped actuating portion 11 having a back surface opened at the center, a fitting portion 12 of the cover body 2 provided on the back surface of the actuating portion 11, and a hooking portion 13 above the actuating portion 11. The leg portion 14 is provided below the operating portion 11, and the shaft portions 15 are provided on both sides of the lower end of the leg portion 14 so as to project. The cover body 2 is composed of a horizontal plate portion 21 and a vertical plate portion 22 which is provided on the edge of the horizontal plate portion 21, and the spring 3 is provided between the back surface of the operating portion 11 and the vertical plate portion 22 of the cover body 2. This is a possible compression coil spring.

In addition, the upper portion and the front portion are opened at the upper edge of the main body A where the latching mechanism is formed, and the opening 4 having a size corresponding to the operating portion 11 of the latching main body 1 is formed. 4, a leg mounting portion 6 is formed which communicates with the lower side of 4 and has a shaft hole 5 in a side surface portion thereof, while a hook portion 7 is formed at a position where the lid B is formed with a hooking mechanism.

Thus, the horizontal plate portion 21 of the cover body 2 is mounted on the cover body fitting portion 12 of the locking body 1, and between the back surface of the operating portion 11 and the vertical plate portion 22 of the cover body 2. With the spring 3 interposed, the leg portion 14 of the latching main body 1 is pushed into the leg mounting portion 6, the shaft portion 15 is fitted into the shaft hole 5, and the operating portion 11 is inside the opening portion 4 of the main body A. It is operably attached to the front and back.

Therefore, the hooking portion 7 of the lid B and the hooking portion 13 of the hooking main body 11 are kept in a hooked state by the urging force of the spring 3, and the main body A and the lid B are fixed to each other. , The operating portion 11 of the latch main body 1 is pressed with a finger or the like, and the latch main body 1 is rotated around the shaft portion 15 against the biasing force of the spring 3 and moved to the back, the lid B The hooked state between the hook portion 7 and the hook portion 13 of the hook body 1 is released, and the cover B can be opened.

The present invention is not limited to the above-described embodiment, but the present invention relates to a fastening mechanism for opening and closing the main body and the lid in a portable warm / cold box. The structure of the lid itself, for example, the heat insulating structure, the built-in pot portion, the attachment of the tableware storage portion, the hinge structure between the main body and the lid body, etc. can be arbitrarily determined, and the shape of the hook body and the cover body can also be set. It can be arbitrarily determined as long as it exhibits a predetermined function.

[0013]

[Effect of the device]

 As described above, according to the present invention, in the portable heat insulation box, the opening and the leg mounting portion are provided at the upper edge of the main body where the hooking mechanism is formed, and the hook portion is provided at the corresponding position of the lid body. A latching mechanism is formed by forming a latching member consisting of a latching main body, a cover and a spring, and combining the above-mentioned latching members appropriately and mounting them in the opening of the main body, etc. Since it is not exposed to the outside, it is easy to manufacture, and the inside of the mechanism is always concealed by the cover body even when the latch main body is operated, and it has the advantage that it has an excellent appearance. is there.
