DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a buckle used for connecting a shoulder belt to a storage case.

[Conventional technology]

Conventionally, as a buckle for connecting the shoulder strap to a storage case such as a hard bag, it is composed of a female body and a male body having an insertion portion into this female body, and the female body is fixed to the storage case,
By attaching the male body to the belt and inserting and engaging the insertion portion of the male body with the female body to connect the female body and the male body,
It is known that a belt is attached to a storage case.

However, most of the above-described conventional buckles use a pressing operation on a female body or a male body as a release mechanism for releasing the connection between the female body and the male body, and therefore the release mechanism is carried when carrying the storage case. If some pressing force is applied from the outside to the connection between the female body and the male body, the belt may be accidentally detached from the storage case.

On the other hand, as a buckle which eliminates the above-mentioned inconvenience and prevents the male body and the female body from being unintentionally released, a buckle having the structure shown in FIG. 9 has been proposed (Japanese Patent Application No. 62-6504).
2).

That is, in the figure, a is a male body, b is a female body, and c is a lid body. This buckle attaches the lid c to the female body b rotatably by inserting the pins d, d of the lid body c into the mounting grooves e, e of the female body b, respectively, and the locking projections of the lid body c. After f and f are inserted into and engaged with the locking grooves g and g of the female body b, the female body b and the lid body c are overlapped and connected, and then the male body a is inserted into the insertion groove portion h of the female body b. The insertion portion i is inserted while elastically deforming the flexible piece i of the female body b rearward. Then, the engaging protrusion k of the flexible piece i is fitted into the engaging hole j of the insertion portion i, and the flexible piece i elastically restores to connect the male body a and the female body b. is there. When releasing the connection between the male body a and the female body b,
The lids c are opened by removing f, f from the locking grooves g, g, and at the same time, the pressing projections 1, 1 of the lids c press the lower end portion of the flexible piece i to elastically deform the insertion. The engaging protrusion k of the flexible piece i is released from the engaging hole j of the portion i, and the insertion portion i of the male body a can be taken out from the insertion groove h.

[Problems to be solved by the invention]

However, the buckle of FIG. 9 described above has a male body a and a female body b.
When the lid c is opened, the lid c is 90 degrees relative to the female body b because the lower end of the flexible piece h is pushed by the pressing protrusions l, l of the lid c when the lid c is released. It spreads only to a certain angle, and therefore, when the lid c is opened, an object may fall on the lid c, collide with it, and the buckle may be damaged. Further, this buckle requires that the lid c be slid slightly upward when the lid c is opened to disengage the locking protrusions f, f from the locking grooves g, g. It is troublesome.

The present invention has been made in view of the above circumstances, and does not inadvertently release the connection between the male body and the female body, and the lid body opens at an angle of 180 degrees with respect to the female body. An object of the present invention is to provide a buckle in which an object does not collide with the lid body and is damaged when the body is opened, and the lid body can be easily opened.
