Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, a broach pin, specifically, a needle (pin) attached to one end of a base is inserted into an object such as clothes, and then locked to a locking portion provided at the other end of the base. The present invention relates to a broach pin that can be pinned to an object.
[0002]
[Prior art]
As shown in FIG. 7, the broach pin includes an elongated base 101, a needle 102, a connecting portion 103 that connects these, a needle locking portion 104, and a needle locking portion cover 105. The needle locking portion 104 that forms the slit 104d stores and locks the distal end portion of the needle 102 through the slit 104d. The needle locking portion 104 has a protrusion 104e so that the needle locking portion cover 105 does not come off. The base 101 has a hole H for fixing a broach.
[0003]
The needle locking portion cover 105 includes an inner hemispherical portion 108 facing in the direction of the connecting portion 103, an outer hemispherical portion 109 facing in the opposite direction to the connecting portion 103, and a connecting portion 107 that connects them. The The hemispherical parts 108 and 109 sandwiching the needle locking part 104 form slits 108d and 109d, respectively. In the case of storing the needle, while moving the connecting portion 107 along the needle locking portion 104 with a finger, it rotates around the axis of the protrusion 104e, and the slits 108d and 109d The slit 104d of the needle locking portion is overlapped. After the needle is introduced in this state, when the connecting portion 107 is moved around the needle locking portion 104 with the finger again and rotated around the axis of the protrusion 104e, the slits 108d and 109d are formed into the slits of the needle locking portion. 104c does not overlap, and the needle can be prevented from coming off when the broach pin is used. Further, the needle locking portion cover 105 is widely used not only for concealing the pointed portion of the needle to enhance safety but also to enhance aesthetic appearance.
[0004]
[Problems to be solved by the invention]
The assembled broach pin is generally completed by performing plating (gold plating, rhodium plating, nickel plating, etc.). However, brooch pins with an antique appearance (antitic gold, antitic silver, etc.) were used for base plating (black gold plating, rhodium plating, nickel plating, etc.), followed by overcoloring (black etc.), barrels, etc. Part of the surface is peeled off and finished with a clear finish. The former is called a general processing broach pin and the latter is called a special processing broach pin. The gold plating is generally performed after nickel plating. The partial surface peeling process is generally performed in a barrel containing a barrel liquid and an abrasive. For the clear finishing process, lacquer clear is usually used.
[0005]
In the specially processed broach pin, there has been a problem of detachment of the needle locking portion cover 105 in the part peeling process using the rotating barrel. On the other hand, if the clearance between the needle locking portion cover 105 and the needle locking portion 104 is reduced in order to prevent detachment, the clearance is blocked by the base plating process, or the clear lacquer is clogged with this clearance in the clear finish. There is a problem that it is difficult to rotate the needle locking portion cover 105 along the needle locking portion 104. The inventor of the present application sets the clearance between the needle locking portion cover 105 and the needle locking portion 104 to a size that is not blocked by the base plating process or the clear finishing process and that does not partially detach at the surface peeling process. Although it was tried, it was difficult because the optimum gap itself fluctuated due to uncertain factors in each process. Further, the present inventor tried to eliminate clogging in the clear finishing process by adjusting the concentration of the clear lacquer, but the success was limited. Furthermore, since the base plating process in the general broach pin plating process and the special broach pin plating process is a common process, only some of the broach pins may be specially processed after this process. When the clearance between the head cover 105 and the needle locking portion 104 is reduced, there is a problem that it is difficult to rotate the needle locking portion cover 105 along the needle locking portion 104 even in a general broach pin. .
[0006]
The present invention provides a broach pin that can prevent the needle locking portion cover from being detached in a partial surface peeling process using a barrel or the like and can maintain the smoothness of rotation of the needle locking portion cover even after a clear finish. To do. The present invention also provides a broach pin having a structure that can be easily manufactured while maintaining such characteristics.
[0007]
[Means for Solving the Problems]
The present invention includes a base, a connecting portion for attaching a needle to one end of the base, a needle attached to one end of the base and extending to the other end of the base, and a longitudinal axis of the base at the other end of the base A needle locking portion that protrudes in a direction to be formed, forms a first protrusion on a surface facing the connection portion, and forms a slit that introduces and locks the distal end portion of the needle from the side; and It has a pair of covering portions arranged so as to sandwich the needle locking portion, and by engaging the first protrusion of the needle locking portion with the inner surface of one of the covering portions, the axis of the protrusion is centered. A broach including a needle locking portion cover that is supported by the needle locking portion so as to be able to rotate and forms a slit that overlaps the slit of the needle locking portion at a predetermined rotation position A pin forming surface of the first protrusion at the needle locking portion; The surface opposite to provide a broach pin and forming a second protrusion which engages the inner surface of the other cover portion of the needle locking cover.
The slit of the needle locking part preferably has a notch for storing the needle. The connecting portion and the needle locking portion are preferably integrated with the base body.
[0008]
[Embodiment]
The shape of the substrate used in the present invention is not particularly limited, and examples thereof include a linear shape, a plate shape, a rod shape, a circular shape, and an elliptical shape. From the viewpoint of ease of fixing the broach, it is preferably an elongated plate, but a curved portion or the like may be provided for decorative purposes. The longitudinal direction of the substrate is, for example, a long direction in the case of an elongated shape, a long diameter direction in the case of an ellipse, and any diameter direction in the case of a circle. The material for the substrate is not particularly limited, and examples thereof include brass, stainless steel, aluminum, gold, silver, copper, and alloys. Since the broach is fixed with a screw or the like at the central portion of the base, one or more holes can be formed.
[0009]
The needle used in the present invention is preferably made of a metal wire having elasticity (spring property). Since the needle is attached to one end of the base and extends to the other end, the needle has the same length as the base. One end of the needle is preferably a pointed tip in order to facilitate the insertion into the object to be pinned. The other end of the needle is attached to the base so that a force can be generated in the direction away from the base due to the resilience of the needle when it is pinned. The other end of the needle is preferably wound around the fixed shaft at the connecting portion, and acts as a spring when the end of the needle is pressed against the base when pinned.
[0010]
The connecting portion constituting the present invention attaches the needle to one end of the base body, and when the pin is pinned to the object, it gives elasticity to return to the needle and takes in a part of the object. In addition, there is no particular limitation as long as a certain distance (usually about several mm) can be secured between the base and the needle. In order to attach the needle to the base body, there are also modes in which the needle is directly welded to the base body, or a shaft bonded to a pair of rising portions in the width direction of the base body is provided, and the needle is wound around this shaft. Preferably, as will be described later, a pair of ears are provided in the width direction of the base, and a pair of protrusions are provided on the ears. When the ear is bent, the projections of the pair of rising portions face each other to form an axis, which is advantageous because the structure can be processed integrally from the base.
[0011]
The needle locking portion constituting the present invention protrudes in a direction crossing the longitudinal axis of the base at the other end of the base (one end different from the one with the connection), and is formed on the surface facing the connection. A first protrusion is formed, a second protrusion is formed on the opposite side, and a slit for introducing and locking the tip of the needle from the side is formed. When the tip of the needle is locked in the slit, the needle has elasticity to return to the state before the lock, so that a force is generated in a direction away from the base, and the needle is held in the slit. From the viewpoint of securely locking the needle, it is preferable that the slit has a small introduction port for the needle and a portion for locking the needle after the introduction has a wider shape than the introduction port, for example, a circular shape.
When pinning to an object such as clothes, the needle is arranged so that there is a certain distance between the base and the needle when the needle is locked to the slit in order to secure a space for taking in a part of the object. A locking part is provided.
[0012]
The present invention is characterized in that protrusions are provided on both sides (inner side) and opposite side (outer side) of the connecting part on the base. By providing protrusions on both sides, the contact area between the needle locking portion and the needle locking portion cover can be increased, and while the partial surface peeling process using a barrel or the like is prevented from falling off during the plating process, Clogging in the clearing process can be prevented. The shape of the protrusion is not limited as long as it can secure a sufficient contact area to prevent dropping and clogging. However, the shape of the protrusion is preferably a hemispherical shape for each protrusion of the needle locking portion cover that covers the needle locking portion from the viewpoint of aesthetics of the appearance. A hemisphere or a shape obtained by deleting the tip of the hemisphere perpendicularly to an axis parallel to the longitudinal direction of the substrate (the cross section is a circle) is desirable.
The inner protrusion has a slit for introducing a needle. The outer protrusion may not be provided with a slit if the needle is short, but it is preferable to provide a slit in terms of securely holding the needle.
[0013]
The slit of the needle locking portion preferably has a notch for holding the needle. If the needle is housed in the notch, the needle has elasticity in the direction away from the base, so that the needle is firmly held in the notch, and the needle is detached during a part peeling process or use using a barrel or the like. The possibility can be significantly reduced. Usually, it is sufficient to provide the notches only in the slits of the protrusions on the side (inner side) facing the connection part, but they may be provided in both the slits of the inner and outer protrusions.
[0014]
The needle locking part cover constituting the present invention is composed of a pair of covering parts and a connecting part for connecting them so as to sandwich the needle locking part. The pair of covering portions are an inner covering portion facing in the direction of the connecting portion and an outer covering portion facing in the opposite direction to the connecting portion. It is preferable from the viewpoint of aesthetics that each covering portion has a hemispherical shape and is substantially spherical as a whole.
The inner covering portion has a slit for introducing a needle. When the needle is shortened, the outer covering portion does not need to be provided with a slit, as is the case with the protrusion on the outer side of the needle locking portion. However, it is preferable to provide a slit from the viewpoint of ensuring the locking of the needle. The slits on the inner cover part must be the same size as the slits on the inner protrusions of the locking parts that they cover, but the slits on the outer cover part are shallower than the slits on the inner cover part. (Small) Good.
The slit of the needle locking portion cover is provided so as to overlap with the slit of the needle locking portion in the needle introduction direction in order to store the needle in the needle locking portion. After the needle is introduced in this state, the needle locking portion cover is rotated by rotating the needle locking portion along the axis of the protrusion of the needle locking portion while pushing the connecting portion of the needle locking portion cover with a finger. And the slit of the needle locking part do not overlap, and the needle locking part cover covers the slit of the needle locking part. Therefore, the needle will not come off during use of the broach pin. In addition to concealing the pointed portion of the needle to enhance safety, it also enhances the appearance aesthetics.
