Description

[Detailed description of the invention] This invention relates to a hair pin made of elastic synthetic resin.Firstly, it can be securely clamped regardless of the amount of hair, secondly, it is easy to use, and thirdly, it is easy to use. It was developed primarily for the purpose of being able to clamp hair well without damaging it.

The details will be explained below based on the drawings. The hair pin according to the invention is an integrally molded product made of elastic soft synthetic resin, and 1 is the upper plate thereof.

The upper plate 1 is an annular plate having external dimensions of approximately 18 mm in the front-to-back width 11 and 62 mm in the left-right length 12, and has a punched hole 2, and is curved in an upward arch shape between the left and right sides. be.

From the center of the lower right end of the upper plate 1, a narrow presser plate 3 is positioned at the center of the lower side and is bent to open downward and integrally extends.

This presser plate 3 is curved upward in the same way as the upper plate 1, with its protruding base end 3a slightly hanging down.

An L-shaped retaining piece 4 is integrally extended from the center of the lower left end of the upper plate 1.

The protruding tip of this retaining piece 4 has an outer circumferential surface 4a excluding the upper surface.
is rounded, and a recessed hole 5 is provided on the top surface of the flat tip.

A protrusion 6 is formed protrudingly on the lower surface of the tip of the presser plate 3.
can fit into the recessed hole 5.

On the upper surface of the presser plate 3, there are spring plates 7 arranged alternately between the left and right sides of the central part.
are also curved into an arch shape and constructed as one.

This spring plate 7 has the same width as the presser plate 3, but has a thinner wall thickness.
Improves elasticity.

Then, when the tip of the presser plate 3 is stopped by engaging with the engagement piece 4 through the engagement between the recessed hole 5 and the protrusion 6, the upper plate 1 and the presser plate 3
A uniform gap 7 is created between the left and right sides, and the spring plate 7
It fits into the punch hole 2 within a range where the upper surface does not protrude from the upper surface of the upper plate 1.

When using the present hair pin, first, the presser plate 3 is removed from the engagement piece 4, and in the open state, the upper plate 1 and the presser plate 3 are inserted so as to sandwich the bundled hair.

At this time, since the presser plate 3 is bent to open downwardly at its extending base end 3a, there is no need to specifically open the presser plate 3.

From this state, the bundled hair is sandwiched between the upper plate 1 and the presser plate 3.

To do this, the tip of the presser plate 3 is pressed against the upper plate 1 side and engaged with the retaining piece 4.

At this time, the tip of the presser plate 3 is connected to the rounded outer peripheral surface 4 of the retaining piece 4.
a and turns around in either the front or rear direction, and then the protrusion 6 is again displaced onto the recessed hole 5 and engages with it, preventing it from coming off unexpectedly.

However, the hair pin of the present invention has elasticity as a whole, and in particular, the spring plate 7 has high elasticity.

Therefore, when the amount of hair to be pinched is small, the hairpin itself does not undergo much elastic deformation, but when the amount of hair is large, the spring plate 7 in particular bends significantly downward as shown in FIG.

The hair also escapes into the punch hole 2 of the upper plate 1 according to the clamping force.

As a result, regardless of the amount of hair, the spring plate 7 deforms the hair so that it is always soft, uniform, and wavy, and can be securely sandwiched between the upper plate 1 and the holding plate 3. be.

As explained above, the hair pin according to this invention has a hole 2 in the upper plate 1 to form an annular shape, and a spring plate 7 is provided in the presser plate 3, so that when hair is pinched, the upper surface of the spring plate 7 is Since it is configured to fit into the punching hole 2, if there is a small amount of hair, the hair will be held in the gap between the spring plate 7 and the punching hole 712,
When a large amount of hair is present, the spring plate 7 curves and is held in the gap 8 between the upper plate 1 and the holding plate 3, so that the hair can be surely held regardless of the amount of hair to be held.

In addition, when securing hair, if the tip of the presser plate 3 is applied to the engagement piece 4 from below, the tip of the presser plate 3 will hit the rounded outer peripheral surface 4a of the retainer piece 4 and wrap around in either the front or rear direction.
The protrusion 6 of the presser plate 3 smoothly engages with the recessed hole 5 on the engagement piece 4 side, which is also convenient.
