CONSTITUTION:In a process for changing the warp direction in the lengthwise direction of warp pieces 2, 2, a pair of warp pieces 2, 2 being parallel at a prescribed interval from a base piece 1 realize a feeler-like structure of a stage beetle closed forcibly at a stop-attaching part 3 in its tip, and are formed to a structure for expanding or closing fall-off stop pieces 6, 6 by changing a scross section shape being orthogonal to the lengthwise direction. In such a state, when a state that a pin 4 is fitted by warping the warp pieces 2, 2 with a finger so as to become a recessed shape to the pin 4 forming side in its lengthwise direction, the pin 4 becomes a structure in which both sides in the vicinity of its tip 24 are inserted and held by the fall-off stop pieces 6, 6, and also, on the contrary, when the warp pieces 2, 2 are warped with a finger so that the opposite side to the pin 4 forming side, the fall-off stop piece 6, 6 are diffused, the pin 4 is removed and pierced into clothes, and it can be stop-attached by warping the warp pieces 2, 3.

Description

[Detailed Description of the Invention] (Object of the Invention) The present invention relates to a safety pin for attaching various accessories such as name tag plates, ribbons, and brooches to fabrics, especially the chest of clothes. The objective is to provide a safety pin with a novel structure that will not easily fall off after being worn.

(Prior art) So-called safety pins are made by fixing a planar U-shaped base to one end of a <-shaped steel wire rod whose inside is formed by a simple coil spring. It refers to a structure in which the needle-like tip at the other end of the ``1<''-shaped steel wire is inserted and removed using the elasticity of the coil spring part. It has been used for a long time as a metal fitting to fasten items such as clothes to clothes.

This traditional safety pin has a simple structure and is inexpensive, and best of all, once it is fitted, the needle tip is pressed into the inner groove of the base by the elastic force of the coil spring. It had the advantage of being relatively hard to come off and safe, as it remained as it was, and with later improved structures, the only way to fit and unfit the needle-like tip into the cap was to use a crank-like operation. However, the handling of fitting and unfitting the needle-like tip into and out of the ferrule is surprisingly cumbersome (especially with crank operation). (This is especially true for improved safety pins that have to be removed), and it is difficult for children, and even adults, to handle them in a somewhat panicky situation and find that they do not fit as intended. Sometimes I find myself in a situation where I can't afford it.

For this reason, in recent years, small paper scissor-shaped devices have been used instead of the traditional safety pins to attach name tag plates to the chest, which have become a must-have item especially at weddings, receptions, seminars, etc. Although safety pins with this structure certainly have an advantage in ease of handling compared to traditional safety pins, it is difficult to use this type of attachment. It is only used by people who wear clothing with clipping points such as breast pockets, and is therefore commonly used by women who often wear clothing without breast pockets. It has the disadvantage that it is not suitable for use in the field, and that if it is touched with something after it is attached, it may easily lose its posture or come off.

In this invention, in view of the above circumstances, we have continued to improve and develop a safety pin that is advantageous not only in terms of handling but also in terms of attachment structure to clothing, and as a result we have finally developed a safety pin as detailed below. We have succeeded in realizing a safety pin with a new structure.

(Construction of the Invention) As clearly understood from the representative embodiments shown in the drawings, the safety pin of the present invention basically consists of the following configuration.

In other words, it is parallel to one side edge of the base piece 1, which serves as a mounting part for a name plate plate, appropriate accessories, etc., or supports a protrusion 11 for such a mounting part, at an appropriate interval. By forming a pair of curved pieces 2, 2 and forcibly closing and fixing their tips, a closed scissors-like shape of a stag beetle is realized, and the pair of curved pieces 2, 2 are juxtaposed between each other. The base 41 of the pin 4 is fixed 12 so that it does not protrude beyond the tip of the bent piece 22, and around the tip of the fixed pin 4,
A supporting piece 5 is formed integrally with the bent piece 2, and one of the pins 4 is attached to the inner edge of each bent piece 2.2 at a position slightly closer to the base piece 1 than the supporting piece 5. This is a safety pin formed with a pull-out correcting piece 6.6 extending in a cross-shaped manner up to the side edge.

The base piece 1 and the warped pieces 2, 2 are made by stamping or other means from an elastic thin steel plate or plastic plate, as shown in the plan view of the assembly process in FIG. Although not shown in the drawings, it is also possible to form the base piece 1 from a plastic material and have the base of the bent piece 2.2 implanted therein. Then, after the curved pieces 2.2 extend parallel to each other at appropriate intervals from one side edge of the table piece 1, the fixing holes 31. shall be.

As a result of the tips of the curved pieces 2, 2 being forcibly drawn and fixed 3, the inner edges of the curved pieces 2, 2 naturally swell to either the front or back, creating a stag beetle with its tips closed. It takes on the shape of a horn, and when you press the bulged side with your finger, it deforms into a bulged shape on the opposite side.

This deformation can be reversibly deformed as long as force is applied from the swollen side, and this reversible deformation is possible as long as the elasticity of the table piece 1 and the warping pieces 2, 2 is not lost. be.

The table piece 1 and the warping pieces 2, 2 that enable such deformation
On the other hand, the substantially linear pin 4 has its base 41 fixed 12 to either the front or back surface of the table piece 1, and the bent pieces 2, 2
shape with the tip extended in the direction of the fastening 3 (however, if the fastening 3
(not beyond the designated area).

The stand piece 1 is further provided with an appropriate attachment part (not shown as an example) such as a hook or Velcro tape (product name) on itself as a structure for attaching a name tag or the like, so that the back side of the name tag or the like can be attached directly. Alternatively, as in the example shown in the figure, only the protruding piece 11 is formed integrally with the stand piece 1, and the attachment hole 11a is used to attach a separately formed name plate or other item. The structure shall be such that the mounting bracket attached to the side can be attached.

In addition, the pair of retaining pieces 6, 6 may be of a left-right symmetrical shape, a left-right asymmetrical one, or asymmetrical ones in addition to symmetrical ones formed from the bent pieces 2, 2, etc., according to the technology of the present invention. It is included in the idea of

Several embodiments of the safety pin of the present invention based on the above-mentioned configuration are shown below together with the drawings.

(Embodiment 1) This example is an example of the most basic structure of the present invention shown in FIGS. 1 to 5 of the drawings.

That is, it extends in the shape of a stag beetle's scissors to one side edge of the base piece 1, which serves as a mounting part for a name plate plate, appropriate accessories, etc., or supports a protrusion 11 for such a mounting part. , a pair of curved pieces 2.2 whose tips are forcibly closed and fastened 3 are protruded and fixed together,
The base 41 of the pin 4 is fixed by placing them side by side between the pair of bent pieces 2.2 so as not to protrude beyond the tip of the bent pieces 2, 2, while fixing the base 41 of the pin 4. As can be clearly seen from the plan view of the mid-assembly shown in FIG.
A support piece 5 is formed extending from one of the bent pieces 2 toward the inner edge of the other bent piece 2, and
At the inner edge of each of the bent pieces 2, 2, which are located slightly closer to the base piece 1 than the support piece 5, a retaining piece 6, 6 is formed, which extends in a cross-shaped manner to the vicinity of one side edge of the pin 4, respectively. It is a safety pin made of

As can be understood from the perspective view shown in FIG. 2 in which the pin 4 is fitted, in this embodiment, the pin 4 is
The tip f@42 comes into contact with the bent recess of the support piece 5 extending from one of the bent pieces 2, and both sides of the pin 4 slightly closer to the base piece 1 are held between the retaining pieces 6.6. It becomes a worn structure. The details of the state in which this pin 4 is fitted are shown in the fifth section.
The main part is shown in an enlarged plan view in the figure.

Even in this example, when the pin 4 is fitted, the clamping structure is always achieved by the retaining piece 6.6, so that the tip 42 can easily be attached to the support piece 5 in normal use.
Although there is no risk of it coming off, the following example shows a structure that further increases safety.

Note that when the pin 4 is removed, the tip 42 of the pin 4 and the portion held between the pair of retaining pieces 6 and 6 are completely released from their respective parts. Realize the structure.

(Example 2) The example shown in FIG. 6 and below,
As shown in the plan view of the half-assembly state in which only the pin 4 is assembled to a piece in which each part is integrally formed by punching out a thin steel plate or the like in Fig. 6, this example has a support piece. Reference numeral 5 designates a safety pin in which the inner edges of a pair of warped pieces 2, 2 extend opposite to each other and are formed in an overlapping shape.

When compared with that of Example 1, as shown in the enlarged plan view of the main part in FIG. 7(a) and the sectional view from B to B in FIG. its tip 42
has a structure in which it comes into contact with the pair of support pieces 5.5, so even if it shifts to either side due to some external factor, it will not come off, and the pin tip @42 will accidentally stick out to the back side. There will be no such fear.

(Embodiment 3) This example is a modification of the usage of the configuration shown in Embodiment 2 above, in which the supporting pieces 5 extend from each inner edge of the pair of bent pieces 2.2 in a mutually opposing manner. Formed in an overlapping manner,
The safety pin is such that the pin tip 42 is sandwiched between the pair of support pieces 5.5.

The fitting between the supporting pieces 5.5 is carried out by starting from the end of the supporting piece 5, which is located on the pin 4 side due to the overlapping condition, and passing under it. By comparison, when the pin 4 is hung, its tip 42 simply connects to the support piece 5.
．． A structure in which the tip 42 of the pin 4 is not only in contact with the pin 5 but also sandwiched between them can be visualized, and the tip 42 of the pin 4 is completely hidden.

(Function) In the safety pin of the present invention having the above-described configuration, the pin 4 is fitted by warping the warped piece 2.2 with a finger so that it has a concave shape on the side where the pin 4 is formed in the length direction. In this state, the pin 4 itself has a structure in which both sides of the pin 4 near its tip 42 are clamped by the retaining pieces 6, 6, and in this state, it can be directly attached to the base piece 1 or as in the embodiment. Attach name tags, phone numbers, and other items to the appropriate places on the back side of the protruding piece 11 formed on the stand piece 1, and store, transport,
to sell.

When using, bend the bent pieces 2, 2 in the opposite direction, that is, with your fingers so that the side opposite to the pin 4 formation side becomes concave in the length direction, remove the pin 4, and release the tip 42. , pierce the released tip 42 into the chest, waist, or other part of the clothing where it is not attached, so that the tip 42 pierces through the clothing, and then bend it again and insert the piece 2.2 with your finger so that it forms a concave shape on the side where the pin 4 is formed. When the pin 4 is bent, the pin 4 is easily fitted, and attachment to clothing is realized.

In the process of changing the warping direction of the warping pieces 2, 2,
A pair of curved pieces 2, 2 parallel to each other at a predetermined distance from the base piece 1 are forcibly fixed 3 at their tips to realize a closed horn-like structure of a stag beetle. As a result, each curved piece 2
,2 is.

When it is in a warped state with a concave shape in the length direction,
The cross-sectional shape perpendicular to the length direction also forms a V-shaped cross section that is concave in that direction.

That is, in the enlarged plan view of the main part with the pin 4 removed in FIG. In the cross section perpendicular to the horizontal direction, as shown in (b) in the same figure, the side opposite to the side where the pin 4 is formed has a concave shape;
In the enlarged plan view of the main part with the pin 4 in Figure (a),
The curved pieces 2, 2 have a concave shape on the surface side of the paper on which the drawing is written, and in the cross section perpendicular to the length direction of the curved pieces 2, 2, the pin 4 is formed as shown in (b) of the same figure. The side is concave and the cross section perpendicular to the length direction is changed by a pair of retaining pieces 6, 6 that are protruded from the inner edge at a predetermined angle. In the process of removing the pin 4 as shown in Fig. 4, the distal end of the retaining piece 6.6 naturally expands, eliminating the pinching structure on both sides of the pin 4. On the other hand, in the process shown in FIG. 5 in which the pin 4 is fitted, the distal ends of the retaining pieces 6, 6 naturally close, shifting to a structure in which both sides of the pin 4 are sandwiched.

In addition, in the structures shown in Examples 1 and 2, it is possible to complete the fitting and unfitting operation of the pin 4 only by the above-mentioned operation.
In σ) shown in Example 3, in addition to changing the warping direction of the warping pieces 2, 2 with your fingers, in order to fit and remove the pin tip @42 between or between the support pieces 5.5, This necessitates an extra fitting/unfitting operation in which the tip 42 of the pin 4 is moved using a crank operation using the base end 41 of the pin 4 as a fulcrum.

(Effect) The safety pin of the present invention realized as described above utilizes the change in the cross section perpendicular to the length direction in the process of changing the warp in the length direction of the warp pieces 2, 2. , the retaining piece 6.6 is made to expand or close naturally, and a jfr4 structure is realized in which the retaining piece 6.6 does not provide equal support when the pin 4 is removed or fitted. As a result, pin 4
When the retaining piece 6°6 is fitted, the retaining piece 6°6 reliably and stably clamps both sides of the pin 4 in the vicinity of the tip 42, making it difficult to change the posture of the pin 4 and making it difficult to point the pin 4. If the part of the clothing that is threaded through it tries to come off in the direction of the pin tip 42 for some reason, the retaining pieces 6, 6 will prevent it from coming off, an excellent feature not found in previous products. These characteristic effects are common to each of the illustrated embodiments representative of this invention, and in particular, in the structure represented by embodiment 1, there are is also the most advantageous in terms of operability, and in Example 2,
This realizes an advantageous structure that further enhances the stability when the pin 4 is fitted while still taking advantage of the good operability. Although it adds some additional cost, it makes it possible to realize a structure with the highest stability during use, making it particularly suitable for use as a safety pin in scenes of rapid movement.

Like soft clay, the safety pin of the present invention has an extremely simple structure, is easy to manufacture and can be provided at low cost, and is superior to conventional safety pins in terms of ease of attachment and removal from clothing. It is even more advantageous than conventional products, and in particular, due to its structural features, it has an excellent effect that has not been seen before in terms of preventing it from falling off after being attached to clothing. Therefore, i&3+IT can be used not only as a regular safety pin, but also as a safety pin for children in kindergartens and elementary schools, as it is truly safe and easy to handle.
