Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to an improvement of a push-type hooking metal fitting used for belts, pants hangings, shoe bands and the like.

(Prior art) In recent years, a so-called push-type hooking metal fitting has been widely used as a metal fitting for hanging a belt or trousers by attaching a receiving metal fitting and an inserting metal fitting to both ends of the belt so that the both metal fittings can be connected or disconnected with one touch. It's being used.

FIG. 10 to FIG. 14 show an example of a conventional metal fitting of this kind. The metal fitting is composed of a receiving metal fitting 22 and an inserting metal fitting 23. At the time of connection, as shown in FIGS. 11 and 12, the outer shape is formed so as to be bilaterally symmetrical.

Specifically, the receiving metal piece 22 has a guide body 25 having support pieces 24 projecting from both sides thereof, and a detention piece 26 pivotably mounted between the support pieces 24 and projecting from the tip toward the guide body 25 side. And a leaf spring 28 which is interposed between the guide body 25 and the draw body 27 and biases the rear part of the draw body 27 in a direction away from the guide body 25.

Further, the insertion metal fitting 23 is formed by projecting a hooking piece 29 which is engageable with the withdrawal piece 26 at the tip end thereof, and the tip end side is guided by the guide body 2.
5, a plug plate 30 that can be inserted between the retractor 27 and
A cover plate fixed to the insertion plate 30 and having a substantially same shape as the guide body 25 having support pieces 31 protruding from both sides, and a cover plate fixed between the support piece 31 of the substrate 32 and substantially the same shape as the draw body 27. And 33.

In FIG. 10 and FIG. 13, 34 is the guide body 2.
5, a belt engaging window 35 of the substrate 32,
6 is an eyelet metal fitting and 37 is a rivet.

Then, when the tip end portion of the insertion metal fitting 23 is inserted between the guide body 25 of the receiving metal fitting 22 and the detention body 27, the tip of the detention body 27 of the leaf spring 28 is fixed by the hooking piece 29 of the insertion metal fitting 23. When the insertion member 23 is pushed up against the elastic force and further inserted into a predetermined position, the retractor 27 is returned to the original position by the elastic force of the leaf spring 28, and the retaining piece 29 is retained by the retaining piece 26. Thus, the insertion fitting 23 and the receiving fitting 22 are connected (see FIG. 13).

On the other hand, when the rear part of the pulling body 27 is pushed down and the insertion fitting 23 is pulled, the engagement piece 29 and the pulling piece 26 are disengaged, and the insertion fitting 23 and the receiving fitting 22 are disengaged. (See Figure 14).

As described above, the hooking metal fitting can be easily connected and disconnected, and has extremely high practical utility. Further, when the two metal fittings 22 and 23 are connected to each other, the outer shape is symmetrical, which is excellent in design.

(Problems to be Solved by the Invention) By the way, the respective parts constituting the receiving metal fitting 22 and the inserting metal fitting 23 of the conventional latching metal fitting are usually formed by press working and are formed in different shapes.

As a result, various types of molds are required to mold each part by press working, which significantly increases the manufacturing cost and
There is a problem that it takes time to replace the mold.

Further, the hooking metal fitting has a major drawback in that the metal fittings 22 and 23 are easily disengaged when the detention body 27 is pushed by an impact or the like.

For example, when the hanging metal fitting is used as a trouser hanging metal fitting for ski pants, the receiving metal fitting 22 and the inserting metal fitting 23 at the chest are used.
Since a vertical pulling force is constantly applied to the ski, if the skier falls and is impacted by the freezing surface of the detention body 27, the engagement piece 29 and the detention piece 26 are disengaged, and the catch 22 However, there was a difficulty that the plug-in metal fitting 23 and the plug-in metal fitting 23 could easily be disengaged.

The present invention was created in order to solve the above problems, and the purpose thereof is to significantly reduce the manufacturing cost, and the metal fittings do not easily dissociate even if an external impact is applied to the metal fittings. It is to provide a latch.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the latching metal fittings of the present invention are arranged in a facing manner, and a bottom plate and a support piece connected to both sides of the bottom plate and bent upward are provided. Two guides of the same shape and swingably mounted between the support pieces of each guide, respectively, and a top plate facing the bottom plate and a retracting member connected to the tip of the top plate and bent toward the guide body. The same shape of the draw body, the elastic body of the same shape that biases the rear part of each draw body in the direction to separate from the guide body, and the tip end of each of the draw bodies to protrude outward from the tip of the guide body. A pair of dual-purpose metal fittings each fixed to a guide body and each having an insertion plate of the same shape provided with a hooking piece that can be hooked on the pulling piece of the tensioning body opposite to the guide piece Is.

(Function) When the dual-purpose metal fittings are made to face each other and the tip end portions of the respective insertion plates are inserted between the guide body and the detention body of the dual-purpose metal fittings facing each other, the hooking pieces of the insertion plates cause the detention bodies to move. The tip is pushed up against the elastic force of the elastic body, and the insertion plates are sequentially inserted into the metal fittings.

When each insertion plate is inserted to a predetermined position, the tip of the retractor is returned to its original position by the elastic force of the elastic body,
The hooking piece is hooked on the pulling piece.

By this, both metal fittings are connected.

Then, when the rear part of the pulling body of each metal fitting is pushed toward the guide body side and both metal fittings are pulled outward, the engagement between the pulling piece and the locking piece is released, and the connection of both metal fittings is released.

Since the dual-purpose metal fittings have the same shape and the same structure, the manufacturing cost can be greatly reduced.

Also, since the two detention bodies and the two insertion plates are engaged with each other, the two metal fittings will not be disconnected just by pushing one demolition body, and the two metal fittings will be disengaged due to impact or the like. Disappears.
