Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention relates to a safety pin for attaching a name tag plate, various accessories such as ribbons and broaches to a cloth, particularly a chest of clothes, and the like. An object of the present invention is to provide a safety pin having a novel structure that will not easily fall off later.

(Prior Art) Speaking of so-called safety pin, a flat U-shaped base is fixed to one end of a "U" -shaped steel wire rod formed in a coil spring whose middle is simple, and the U-shaped base is fixed. It is a structure in which the needle-shaped tip of the other end of the "U" shaped steel wire rod is fitted and removed by utilizing the elasticity of the coil spring part.The nameplate plate is rigid, ribbon, brooch, etc. It has long been used as a metal fitting to fasten clothes to clothes.

The safety pin of this traditional structure is simple and inexpensive to provide, and above all, once fitted, the needle-like tip is pressed into the inner groove of the base part by the elastic force of the coil spring part. It had the advantage that it could be worn as it was, and it was relatively hard to come off and it was safe.After that, in the case of the improved structure, the needle-like tip can be operated like a crank to remove it from the mouthpiece. Some of them have been made impossible to implement without doing so, and their safety has been further enhanced, but the handling of fitting and removing the needle-like tip on the mouthpiece seems to be easy at first glance, but it is unexpectedly troublesome (especially when cranking. This is especially true for the improved safety pins that must be used), and not only for children, but for adults as well, when dealing with them in a somewhat panicked situation, it fits in quite easily. And it is only sometimes would fall into a situation that is not me.

For this reason, recently, as a fixture to the chest of the name plate, which has become an indispensable item especially for weddings, receptions, seminars, etc., a small paper scissors-like device has been used instead of the traditional safety pin. However, with this structure, it is possible to use this mounting tool, although it is certainly advantageous in terms of handling compared to traditional safety pins. Only those who wear clothes that have pinch points such as breast pockets are therefore not suitable for use by women who often wear clothes that do not have these breast pockets. However, it has a drawback in that it has a drawback that if it touches something after it is attached, it may easily lose its posture or be detached.

In view of the above circumstances, the present invention has improved and developed a safety pin that is advantageous not only in terms of handleability but also in terms of the structure for attaching to clothes. As a result, as will be described in detail below. We have succeeded in realizing a safety pin with a new structure.

(Structure of the Invention) As will be clearly understood from the typical embodiment shown in the drawings, the safety pin of the present invention basically has the following structure.

That is, a pair of parallel plates are provided at appropriate intervals with respect to one side edge of the stand piece 1 which becomes an attachment part for a name tag plate, an accessory, or the like, or which supports a protruding piece 11 for these attachment parts. By forming the warped pieces 2,2 of the stag beetle, and forcibly closing the tip and fastening them, the scissor-like shape of the closed stag beetle is realized, and the pair of the warped pieces 2,2
The base portion 41 of the pin 4 is fixed 12 so that it does not protrude from the tip of the curving pieces 2 and 2, while the tip of the fixed pin 4 is integrated with the curving piece 2. The curved support pieces 5 are formed, and the warp pieces 2, 2 at positions slightly closer to the base piece 1 than the support pieces 5 are formed.
The safety pin is formed by forming retaining pieces 6, 6 extending in an intersecting manner up to one side edge of the pin 4 on the inner edge thereof.

As shown in the plan view showing the state in the assembly process of FIG. 3, the base piece 1 and the warped pieces 2, 2 are integrally punched or formed by a resilient thin steel plate or a plastic plate. Although not shown, it is also possible to form the pedestal piece 1 with a plastics material and to implant the roots of the warp pieces 2, 2 therein. Then, after the warp pieces 2 and 2 extend in parallel from one side edge of the base piece 1 at an appropriate interval, the fastening holes 31 and 31 formed at the tip end thereof are forcibly pulled and fixed. And

The tips of the warped pieces 2 and 2 are forcibly pulled and fixed.
As a result, the inner edges of the warp pieces 2, 2 naturally become bulging on either the front or back side, so to speak, like the horned stag beetle with closed ends, and press the bulged side with your fingers. And it will deform into a bulge on the opposite side. This deformation can be reversibly deformed as long as a force is applied from the bulge side, and this reversible deformation can be performed as long as the resilience performance of the base piece 1 and the warping pieces 2, 2 is not lost. is there.

In contrast to the stand piece 1 and the warp pieces 2 and 2 that can be deformed in this way, the substantially linear pin 4 has its base 41 fixed to either the front side or the back side of the stand piece 12, and the warp piece 2 Fastening 3 of 2,
It is arranged in such a manner that the tip is extended in the specified direction (however, it does not exceed the portion where the fastening 3 is attached).

As a structure for attaching a name tag or the like to the table piece 1, a hook, a velcro (product name), or other suitable attachment portion (not shown) is formed on the table piece 1 to directly attach the back side of the name tag or the like. It has a structure to be worn, or as in the example shown in the figure, only the projecting piece 11 is formed on the stand piece 1 and the attaching hole 11a is used to form a name tag which is formed separately. The structure shall be such that the attachment metal fittings on the side of can be attached.

The pair of retaining pieces 6 and 6 are not limited to the left-right symmetrical type, the left-right asymmetrical type, or the outer side of the warped pieces 2, 2 formed symmetrically, and the asymmetrical type of the present invention. Included in the spiritual thought.

Some embodiments of the safety pin of the present invention based on the above-mentioned structure are shown below with reference to the drawings.

(Embodiment 1) This example is one example of the most basic structure of the present invention shown in FIGS.

That is, it extends like a stag beetle scissors to one side edge of the stand piece 1 which becomes an attachment part for a name tag plate, an accessory or the like, or supports a protrusion 11 for the attachment part, A pair of warp pieces 2,2 whose ends are forcibly closed and fixed 3 are projected and integrated, and are juxtaposed between the pair of warp pieces 2,2 to form a warp piece 2,2.
Make sure that it does not stick out from the tip, and base 41 of pin 4
The fixed end 42 of the pin 4 that is fixed.
As is clearly understood from the plan view in the middle of the assembly shown in FIG. 3, there is a support extending from one of the warp pieces 2, 2 toward the inner edge of the other warp piece 2. The receiving piece 5 is formed, and the inner edges of the warp pieces 2, 2 at positions slightly closer to the support piece 5 than the supporting piece 5 are crossed to one side edge of the pin 4, respectively. It is a safety pin formed by forming extended retaining pieces 6,6.

As can be understood from the perspective view of the state in which the pin 4 shown in FIG. 2 is fitted, the pin 4 is not included in this embodiment.
42 of the pin 4 abuts on the bent recess of the support piece 5 extending from the one warp piece 2, and both sides of the pin 4 slightly closer to the base piece 1 are held by the retaining pieces 6 and 6. It has a different structure. Details of the state in which the pin 4 is fitted are shown in the enlarged plan view of the main part of FIG.

In this example as well, since the retaining structure is always realized by the retaining pieces 6 and 6 when the pin 4 is fitted, the tip 42 easily comes off from the supporting piece 5 in the normal use state. Although there is no fear that it will occur, the structure shown in the next example has a structure that further enhances its safety.

In addition, when the pin 4 is removed, as shown in the perspective view of FIG. 1, a structure in which the tip 42 of the pin 4 and the portion held by the pair of retaining pieces 6, 6 are completely released from the respective portions To realize.

(Embodiment 2) Of the embodiment shown in FIG. 6 and subsequent drawings,
As shown in the plan view in the middle of assembling in which only the pins 4 are combined with the one in which the respective parts are integrally formed by punching out the thin steel plate in FIG. A safety pin 5 is formed so as to extend from each inner edge of the pair of warp pieces 2, 2 so as to face each other and to be formed in an overlapping shape.

Compared with the first embodiment, as shown in the enlarged plan view of the main part of FIG. 7 (a) and the sectional view (b) B-B of FIG. 7, in the state where the pin 4 is fitted, Its tip 42
Has a structure in which it abuts against the pair of support pieces 5 and 5, and even if it is displaced to either side due to some external factor, it will not come off, and the pin tip 42 will accidentally protrude to the back side. There is no danger.

(Example 3) This example is a modification of the mode of use of the configuration shown in Example 2 above, in which the support piece 5 extends from each inner edge of the pair of warp pieces 2, 2 in a mutually opposing manner. The safety pin is formed in an overlapping shape so that the pin tip 42 is sandwiched between the pair of support pieces 5, 5.

The fitting between the support pieces 5, 5 is carried out by wrapping under the end of the support base 5 located on the pin 4 side in an overlapping manner. By comparison, pin 4
In the state where the pin 4 is hooked, a structure can be realized in which the tip 42 not only abuts on the support pieces 5, 5, but is sandwiched between them, and the tip 42 of the pin 4 is completely hidden. Become.

(Operation) In the safety pin of the present invention having the above-described structure, the warp pieces 2, 2 are fitted with the pin 4 by bending them with fingers so as to form a concave shape on the pin 4 formation side in the length direction. Then, the pin 4 itself has a structure in which it is naturally sandwiched on both sides in the vicinity of the tip 42 by the retaining pieces 6 and 6, and in this state, directly on the table piece 1 or as in the embodiment. A projecting piece 11 formed on the piece 1 is attached with a name tag, a ribbon, and other suitable places on the back side of the thing to be attached, and stored, transported, and sold.

At the time of use, once the warp pieces 2, 2 are bent in the opposite direction, that is, in the length direction so that the side opposite to the pin 4 forming side has a concave shape, the pin 4 is removed, and the tip 42 is released. The released tip 42 is pierced through a place to be attached, such as the chest or waist of the clothes, and the tip 42 is made to penetrate through the clothes, and then the warp pieces 2 and 2 are again made into a concave shape on the pin 4 forming side with a finger. When bent, the pin 4 is easily fitted, and attachment to clothes is realized.

In the process in which the warp direction of the warp pieces 2, 2 changes, a pair of the warp pieces 2, 2 which are parallel to each other at a predetermined interval from the base piece 1 are formed.
As a result of realizing the horned structure of stag beetle 2 which is forcibly fixed at its tip 3 and closed, each warp piece 2,2
In the warped state having a concave shape in the length direction, a cross section orthogonal to the length direction forms a C-shaped cross section that also has a concave shape in that direction.

That is, in the enlarged plan view of the main part in a state where the pin 4 of FIG. 4 (a) is removed, the warp pieces 2,2 have a concave shape on the back side of the paper in which the drawing is described, and the length of the warp pieces 2,2 is long. In the cross section orthogonal to the vertical direction, as shown in (b) of the same figure, the side opposite to the pin 4 forming side has a concave C shape, and conversely, the pin 4 of FIG. 5 (a) is fitted. In the enlarged plan view of the main part of the state, the warp piece 2,2, the surface side of the paper described in the drawing is a concave shape, in the cross section orthogonal to the longitudinal direction of the warp piece 2,2,
As shown in (b) of the same figure, the side on which the pin 4 is formed has a concave V shape.

The change of the cross section orthogonal to the longitudinal direction of the warp pieces 2, 2 is related to the relative postures of the pair of retaining pieces 6, 6 protruding on the inner edge thereof at a predetermined angle, and In the process of reaching the state shown in Fig. 4, the retaining piece 6,
In the process of reaching the state shown in Fig. 5 in which the tip direction of 6 widens to eliminate the clinging structure on both sides of the pin 4 and the pin 4 is fitted in reverse, the tip direction of the retaining pieces 6, 6 naturally The structure shifts to a structure in which both sides of the pin 4 are closed and clamped.

In addition, in the structure shown in Examples 1 and 2, the fitting / dismounting operation of the pin 4 can be completed only by the above-mentioned operation.
In the third embodiment, in addition to changing the warp direction of the warp pieces 2, 2 with fingers, the pin tip 42 of the pin 4 is inserted or removed between the support pieces 5, 5 or between the support pieces 5, 5. An extra fitting / dismounting operation for cranking the tip end 42 side with the base end 41 as a fulcrum is required.

(Effect) The safety pin of the present invention, which is realized as described above, uses the change of the cross section orthogonal to the length direction in the process of changing the warp in the length direction of the warp pieces 2 and 2 to prevent the escape. Stop piece
These 6 and 6 are made to open or close naturally, and these retaining pieces 6 and 6 are also used when the pin 4 is removed or fitted.
Has an excellent feature that it realizes a structure that does not come to support anything. As a result, in the state where the pin 4 is fitted, the retaining pieces 6 and 6 are securely and stably attached to the pin 4. Since both sides near the tip 42 are attached to each other, it becomes difficult to change the posture of the pin 4, and if the clothing part pointing to the pin 4 tries to come out toward the pin tip 42 for some reason, this The slip-out prevention pieces 6 and 6 have an excellent effect of preventing the slip-out and preventing the slip-out from being seen in the past.

These characteristic effects are effects common to the illustrated respective embodiments of the present invention, and particularly the structure represented by the first embodiment is most advantageous in terms of structure and operability. And in the second embodiment,
This is to realize an advantageous structure that further enhances the stability in the state in which the pin 4 is fitted while making good use of the good operability as it is. Furthermore, in the third embodiment, the operability is somewhat complicated in terms of operability. However, it is possible to realize a structure having the most stability during use, and it is possible to make the structure particularly suitable as a safety pin in a scene where the movement is intense.

As described above, the safety pin of the present invention is extremely simple in structure, is easy to manufacture and can be provided at low cost, and is easy to attach to and remove from clothes. It is more advantageous than the ones, especially because of its structural characteristics, it has an excellent effect not seen in the past in terms of the fall-out prevention function after it is attached to clothes. Therefore, it can be used not only as a normal safety pin, but also as a safety pin used by kindergarten and elementary school children, which is truly safe and easy to handle.
