Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector for detachably attaching a strap for suspending an article, such as a portable thermos flask, to the article.

[Conventional technology]

Conventionally, when attaching a strap to a portable thermos flask, for example, a ring was fitted into a pair of mounting holes formed in the body of the thermos flask, and the ends of the strap were attached directly to the rings, or eggplant rings were attached to both ends of the strap. The strap was then attached by fitting this eggplant ring into the ring.

[Problem that the invention attempts to solve]

However, when attaching the strap directly to the ring, it is time-consuming and troublesome to attach and detach it, and when using an eggplant ring, the problem is that the eggplant ring is highly rigid and requires a large force to open the ring. It was hot.

[Means for solving problems]

The present invention has been made in order to solve the above-mentioned problems, and the connecting fixture is formed with an insertion hole provided with a locking part that protrudes inward from the hole wall, and the locking fixture is on one side of the insertion hole. The insertion part to be inserted into the insertion hole of the connecting holder and the strap attachment part to which the strap is attached on the other side are formed by a frame body joined at an acute angle, and the frame body of the insertion part a lock, one end of which is fixed to the frame insertion end, the other end of which extends to the joint between the insertion portion and the strap attachment portion, and which engages with a locking portion provided in the insertion hole on the surface; It is characterized by being provided with an operating section consisting of a tongue-shaped elastic piece provided with a protrusion.

[Effect]

In the present invention, in order to attach the strap to an article such as a thermos flask, the hook to which the strap is attached is inserted into the insertion hole of the connecting holder provided on the article from its insertion portion side. Then, the locking protrusion on the tongue-like elastic piece hits the locking part of the connection receiver, and when it is further inserted, the tongue-like elastic piece is pushed by the locking part of the connection receiver and bends elastically, causing the tongue-like elastic piece to bend elastically. The locking protrusion of the protrusion moves over the locking part of the connection receiver and moves to the back side of the locking part. Then, the tongue-shaped elastic piece returns to its original position due to the action of elasticity, the locking protrusion on the tongue-shaped elastic piece engages with the locking part of the connecting bracket, and the locking element is inserted into the connecting bracket. It won't come out through the hole. This attaches the strap to the article.

When the strap is removed, the free tip of the tongue-like elastic piece extending to the joint between the insertion part of the hook and the strap attachment part is pushed in the direction in which it is elastically deflected during insertion. Then, the locking protrusion of the latching tool comes off from the latching portion of the connection receiver. In this state, pull out the hook from the insertion hole of the connection holder and remove the strap.
