DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the provision of a stopper used to hold an open / close lid provided at an opening portion via a hinge in an open state.

[Prior art] The opening / closing lid provided at the opening portion via a hinge is:
Generally, the lid is often urged to the side that closes the opening, and the lid itself is often closed by this urging force while the lid is being opened, which has the disadvantage of significantly impairing its workability. I was

In addition, even when such an opening / closing lid is not provided with a biasing means, the lid that has been opened may be closed unexpectedly by being blown by the wind or hitting an object. .

In particular, when the hinge portion of the lid is provided at the upper edge of the opening, the lid that has opened upward will fall to the closing side unless it is always supported by hand, etc. The work was extremely complicated.

Thus, various methods have been attempted for supporting the opening / closing lid provided at the opening through a hinge at the open position.

The hinge shown in FIG. 10 is one of the typical ones. When the opening / closing lid D 'attached to the opening H' portion of the main body P 'by the hinge 11 is opened (in the drawing, it stands up). The opening / closing lid D 'has an elastic locking piece 12 for locking a side edge d' on the edge side of the opening H '.

The elastic locking piece 12 extends a gap between one side edge of the opening H 'and the lid D' to support a side edge d 'of the lid D' opened from the opening H '. A support piece 12a provided upright on the main body P 'on the line, and a locking projection 1 provided on the side of the lid D' provided along the upright direction of the support piece 12a.
2b, and a lid D 'opened from the hinge 11 portion
The lid D 'is opened by pushing and opening the locking projection 12b outwardly at the side edge d' of the opening. When the side edge d 'has passed through the locking projection 12b, the lid D' is opened. By stopping, the lid D 'is locked by the locking projection 12b, and the movement toward the closing side is sealed.

[Problem to be Solved by the Invention] However, in such a conventional hinge structure, the elastic locking piece 12 provided on the hinge is set upright from the surface of the main body P 'which is flush with the opening H'. It has to be provided, and there is a problem that the work performed at the peripheral portion of the opening H 'is hindered. In addition, since such elastic locking pieces 12 protrude from the main body P 'on the peripheral surface of the opening H', tools or other articles can be housed in close contact with the front surface of the main body P ', or the equipment, etc. In addition, it is difficult to equip the elastic locking piece 12 in the protruding state with the appearance of the opening H ', and it is liable to be damaged by carrying in or out of an article or the like.

The stopper according to the present invention has a configuration in which only the locking projection of the stopper protrudes from the surface of the opening as compared with the conventional means for maintaining the lid in the open state, and the appearance of the opening is clear. In addition to the stopper, the workability at the front of the opening is not impaired at all, and the space at the front of the opening can be utilized as it is. It is intended to be provided.
