Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a fastening device that is attached to clothing, bags, ornaments, etc. where it is necessary to easily put on and take off, and in particular, to ensure a secure holding force when being put on. At the same time, it provides a structure that facilitates installation and removal.

``Prior Art'' Conventionally, a spring hook used as a simple fastening device for clothing, etc. has a male and female engaging part that is detachably engaged with a circular concave member 21 and a convex member 22 made by pressing a metal plate. On the concave member 21 side, a notch groove 23 is formed on both sides of the concave portion, and a substantially C-shaped bend parallel to the inside is formed to apply a pressing force inward from both sides of the notch groove 23. A spring 24 having a section was installed.

"Problems to be Solved by the Invention" According to the structure of the conventional spring hook described above, the holding force when the concave member 21 and the convex member 22 that constitute the male and female engaging parts are attached is exclusively due to the elasticity of the spring 24. of member 22 (
Since the holding force is obtained by sandwiching the fin portion 25 from both sides, its elasticity determines the holding force.
Spring 24 requires force to operate and long-term use
They tend to bend or have less elasticity, and if the elasticity is weakened, it becomes easier to install, but it has drawbacks such as a decrease in holding power and a tendency to come off easily. Particularly when used outdoors, dust tends to enter the concave member 21 side, and once the spring 2
If the mounting portion of No. 4 becomes clogged with sand and becomes fixed, it becomes unusable.

``Means for Solving the Problems'' The present invention eliminates the drawbacks of the conventional locking devices described above, and provides a locking device having male and female engaging portions that are removably locked using a concave member and a convex member. In this method, cutout grooves are formed on both sides of the concave portion of the concave member, and elastic members are installed to apply a pressing force inward from both sides of the notch groove, while the above-mentioned elastic members are provided on both sides of the convex portion of the convex member. It is formed by forming a cut groove of a required depth corresponding to the protrusion of the elastic member, thereby providing a structure that ensures a reliable holding force during installation and facilitates installation and removal.

``Embodiment'' The present invention will be described with reference to an embodiment shown in the drawings below. In FIG. and convex member 2
are each formed by pressing a metal plate or the like. In addition, an appropriate recess 3 is formed in the center of the recessed member 1, an appropriate edge 4 is formed around the periphery, and cutout grooves 5 with appropriate widths are formed on both sides of the recess 3. are doing. On the inside of this edge 4, a spring 7 having a holding member 6 bent in parallel to the inside in a substantially C-shape is mounted as an elastic member using, for example, a piano wire, and is pushed inward from both sides of the notch groove 5. While the holding member 6 is installed to apply pressure,
A convex portion 8 corresponding to the concave portion 3 is provided at the center of the convex member 2.
A cut groove 9 having a required depth corresponding to the protruding part of the holding member 6 is formed on both sides of the convex part 8.

FIG. 4 shows another embodiment, in which an inclined portion 10 is formed on one side of the recessed portion 8 of the recessed member 1 and extends obliquely along the direction of the holding member 6. In this case, the spring 7
It is desirable that the holding member 6 is formed in a square shape with the inclined portion 10 side slightly opened.

"Operation" With the above configuration, the notch 9 of the convex part 8 of the convex member 2 is aligned with the notch groove 5 of the concave part 3 of the concave member 1 and is pressed, thereby being held against the elasticity of the spring 7. The member 6 can be expanded and the convex portion 8 can be fitted into the recess 3, and when the holding member 6 returns, the holding member 6 can enter into the cut groove 9 and lock it. At this time of attachment, the concave member 1 and the convex member 2 are engaged with the cut groove 9 so that the holding member 6 bites from both sides, and a reliable holding force can be ensured against a pulling force. In this state, by rotating the convex member 2 approximately 90 degrees with respect to the concave member 1, the holding member 6 and the cut groove 9 are disengaged, their engagement is released, and the two can be easily separated.

Further, by forming an obliquely extending inclined part 10 continuous to one side of the recessed part 8 as shown in FIG. 4, the protruding part 8 of the protruding member 2 can be guided along the inclined part 10, and the convex part 8 of the protruding member 2 can be guided by pressing. The convex member 2 can be easily attached, and by guiding the convex member 2 along the inclined portion 10, the convex member 2 can be easily removed without rotating.

The concave portion 3 and convex portion 8 are not limited to a cylindrical shape, but may be of any shape such as an oval shape or a square shape as long as both can be rotatably mounted.

"Effects of the Invention" As described above, it is possible to easily attach the convex member with one touch by aligning the notch of the convex member with the notch of the concave member and pressing or sliding diagonally. At the time of this installation, the concave member and the convex member engage with each other in such a way that the holding member bites into the cut groove from both sides, and even if you try to pull them apart, they cannot be removed unless the engagement is released. A holding force with sufficient mechanical strength can be ensured for the engaging portion. Furthermore, by rotating the convex member approximately 90 degrees or sliding it diagonally relative to the concave member, the engagement can be released, and the two can be easily separated. In particular, when engagement and disengagement involve rotation of approximately 90 degrees, since the directions of the two are different, the attachment and detachment operations can be ensured.

In addition, when using a slide, it is easy to remove the convex member, and it is also effective as a locking device for a band member that cannot be rotated, such as a shoelace. Furthermore, unlike the conventional type, the holding force does not depend on the elasticity of the spring, so the holding force does not decrease even after long-term use. Furthermore, even if sand gets into the mounting part, it will be removed by the rotation of the convex part, and the spring will not be fixed and will not become unusable.

In addition, when this engagement is released, it is possible to obtain a dynamic action in which the convex member is flipped up together with a restoring force due to the elasticity of the holding member and instantly removed. As a result, it can be provided as a fastening device for clothing, bags, and other fancy products with a new feel, and furthermore, it is possible to construct an interesting toy using this action.
