Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pin (safety pin ... hereinafter referred to as a pin) sold in a stationery store or the like.
It depends on the manufacturing method of. [0002] Conventional pins are widely used today and are very convenient. However, most of the manufacturing methods are those which are manufactured by an automatic machine using a metal wire and a thin sheet metal as materials. The conventional manufacturing method using the metal wire and the sheet metal has many steps and is complicated. Furthermore, this conventional pin requires a gaze when the needle part is detached, which causes a lot of time loss. [0003] Even in a production system using an automatic machine, when the number of processes increases, time is wasted, machine consumption, power consumption, etc. increase. This leads to high costs and greatly affects the product price. In order to manufacture things, it is important to minimize the number of material items that make up the product. Further, it is desired that the product that is commercialized is graceful and elegant and can be easily used. Means for Solving the Problems In order to solve the above problems, a method of manufacturing a pin of the present invention, which is a means for solving the above problems,
It will be explained while following the figure. The material constituting the present invention is a thin metal wire, which has a high steel quality and is rich in flexibility. FIG. 1 is a perspective view formed by using a metal wire.
The piece (2) extends from the end (1) of the metal wire to the bend angle (3), and this piece (2) has a spiral shape as shown in FIG.
Therefore, it is called a spiral body. The metal wire of the spiral body of this piece (2) is one extra round. In other words, one round and 1/16, or one round and 2-3 mm. In another way, one roll and 2-3 mm,
3mm is more than one roll. As a matter of course because of the spiral shape, the metal wire of 2 to 3 mm near the end (1) of the metal wire keeps a small groove interval (14) from the part of the piece (2) near the bending angle (3) ( The reason why such a complicated expression is used is due to the action described below. The bend at the corner (3) is
It is a bend that can be clearly distinguished from the spiral body of the piece (2),
It is the end bend of the spiral. The bending angle (3) to the bending angle (5) is a piece (4), and the length of the piece (4) is relatively short. The most important parts in the method of manufacturing the pin of the present invention are the spiral body of the piece (2) and the piece (4),
The length and position of the piece (4) and the shape and position of the spiral body of the piece (2) have structural significance (the spiral body and the piece (4) of the piece (2) will be described in detail in the operation [0005] below. Note). The bend at bend (5) is approximately a right angle. The bending angle (5) to the bending angle (7) is a piece (6), and the length of the piece (6) is a relatively short piece. The bend at bend (7) is approximately a right angle. The bending angle (7) to the bending angle (9) is a piece (8), and this piece (8) is located at a position slightly separated from the spiral body of the piece (2) and is the longest piece. The bend at bend (9) is approximately a right angle. The bending angle (9) to the bending angle (11) is a piece (10), and the length of the piece (10) is the shortest piece.
The bend of the turn (11) is slightly larger than each of the other turns. The piece (12) extends from the bending angle (11) to the tip of the metal wire (13), and the length of the piece (12) is the second longest after the piece (8). The tip (13) of the metal wire is sharpened like a needle. [Operation] The pin of the present invention according to the above is provided with a piece (1
After passing 2) through the fabric, put the part (15) slightly closer to the tip (13) of the piece (12) in the helix of the piece (2). However, to put it another way, it would be common sense to date that the helix of piece (2) could not be inserted depending on the position of piece (12). Piece (2)
The method of putting the part (15) of the piece (12) in the spiral body of the. (B) As shown in the perspective view of FIG. 2, the piece (4) is twisted like a semicircular arrow. By this twist, the groove interval (14) of the spiral body of the piece (2) becomes a through groove interval from the position of the piece (12), and the part (15) of the piece (12) becomes the spiral body of the piece (2). Can be put in. (B) As shown in the side view of FIG.
Place 5) on the spiral body of piece (2), and push the position of the arrow in the direction of the arrow. Pushing the part (15) of the piece (12) mounted on the spiral body in the direction of the arrow
It will push the spiral of piece (2) and piece (4). Then, the state shown in FIG. 4 is obtained, and the groove interval of the spiral body of the piece (2) becomes the through groove interval of the piece (12), and the part (15) of the piece (12) is put in the spiral body of the piece (2). You can In other words, pushing the position of the arrow in the direction of the arrow is to pinch it with two fingers. Put your thumb on the position of the game piece (8) at the bend angle (3), put the index finger on the part of the piece (12) and the bend angle (3), and apply a little force. Pinch. The piece (4) is capable of moving vertically and horizontally due to the flexibility of the metal wire connected to the piece (6). Therefore, if the piece (4) and the piece (6) are too short, the flexibility is reduced, and if the piece (4) and the piece (6) are too long, they are too flexible.
In order to allow the spiral body of the piece (2) to move up, down, left and right, the spiral body of the piece (2) must be kept at a position slightly apart from the piece (8). The shape in which a metal wire is wound around a spiral is tubular when the viewing position is viewed from the direction in which the spiral extends. From another perspective, one side is a series of open grooves. The pin of the present invention focuses on the spiral shape of the piece (2), which can be changed from the spiral shape of the piece (2) to the shape of the spiral shape of the piece (2) with respect to the piece (12) starting from the bending angle (11). Then, the part (15) of the piece (12) is used for disconnecting to form a pin shape. Therefore, the use of the spiral body is minimized, and the winding of the metal wire is about 1/16 and one round, or about 2 mm and one round. Only the rod-shaped form can be used as such a spiral body as a cylinder or a groove having one open end. The piece (12) of the pin according to the invention corresponds to its rod form. Due to (a) and (b) in this section, the part (15) of the piece (12) guided by the groove of the spiral body returns to the normal position together with the repulsive force of the metal wire of the piece (6) and the piece (4). , It fits into the tubular shape of the spiral body of the piece (2) starting from the position of the bend angle (11). In this case, the portion (15) of the tubular piece (2) that fits in the tubular shape does not come off from the spiral body regardless of how the entire pin moves. Next, the part (15) of the piece (12) that is set in the spiral body is released from the spiral body. Fix the entire pin and push the spiral body with your fingertip in the direction of the arrow shown in FIG. The portion (15) of the piece (12) is released from the spiral body by the repulsive force of the metal wire of the piece (10) and the piece (12) simply by pushing it with a fingertip. [Example] [0006] In order to prevent the cloth passed from the needle tip of the tip (13) of the piece (12) from moving to the piece (10) via the bend angle (11), It is also possible to bend the metal wire inside the closer piece (12) to provide a protrusion (side view in FIG. 3). [0007] The structural material of the pin of the present invention is only a metal wire. Therefore, the number of manufacturing processes can be reduced. Further, since the shape is simple, it is possible to mass-produce extremely easily. As a result, production costs can be reduced and product prices can be kept low. In use, it is safe because the three pieces of piece (4) piece (6) piece (8) protect the needle. It is easy to remove the part (15) of the piece (12) from the spiral body and can be used with one touch. It is possible to make a product with an elegant shape.
