DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piercing apparatus suitable for forming a small hole in an earlobe or the like for wearing a piercing or the like.

[0002]

2. Description of the Related Art In recent years, pierced earrings (commonly known as pierced earrings) in which a small hole is formed in a mounting portion such as an earlobe and a needle portion is inserted into the small hole have become popular, especially among young women.

[0003] In order to form a stoma in the earlobe, it is first necessary to drill the hole by very simple surgical means. Therefore, as a conventional hole-piercing tool 3, one shown in FIG. 20 is described in Japanese Utility Model Laid-Open No. 1-74815. The hole-piercing tool 3 is one in which one end 4a of a metal thin tube 4 is formed sharply and sharply, and the bar-shaped portion 2a of the piercing hole protector 2 is inserted from the other end 4b, and is used as follows. You. First, the thin tube 4 is pierced from one side of the earlobe, and is pushed in until the flange portion 2b of the piercing hole protector 2 comes into contact with the earlobe.
Next, only the thin tube 4 is extracted from the other surface side of the earlobe, and the piercing hole protector 2 is left in the earlobe.

[0004]

However, even if this hole-piercing tool 3 is used, it is difficult to quickly and safely penetrate the target position of the earlobe because the initial penetrating operation often depends on human labor. If it is not easy and it takes time to remove the thin tube, the person receiving the treatment will feel extra pain, and even the person performing the treatment will be familiar with the earlobe, even though it is an earlobe, equivalent to a blade Technology was needed.

The present invention has been made in view of the above circumstances, and a piercing hole can be quickly, easily, and safely opened at a target position of an earlobe by using a hole opening tool. It is intended to provide a piercing device.

[0006]

Means for Solving the Problems As means for solving the above problems, a pierced hole protector having a flange portion at one end of a rod-shaped portion, and a rod-shaped portion of the pierced hole protector are inserted into the inside from one end. A piercing device is used to open a piercing hole in the earlobe and insert a protection device for the piercing hole, using a piercing device made of a thin tube that is inserted and the other end is formed sharp.

This piercing device has an earlobe holding mechanism for holding the earlobe when the hole is made to penetrate the earlobe, a piercing mechanism for pressing the piercing tool against the earlobe, and operating in synchronization with the piercing mechanism. A device body having a removing mechanism for removing only the thin tube while leaving the piercing hole protective device from the earlobe through which the hole-piercing device has penetrated by the hole-piercing device, and the hole-piercing device is loaded inside and is detachably attached to the device body. The cartridge has a through-hole into which the hole-piercing device is loaded, and is inserted into the through-hole with the hole-piercing device sandwiched therebetween. And a pair of guide members that are pushed out of the through hole together with the hole punch.

In this case, the earlobe is pressed by the earlobe holding mechanism to aim at a desired position, and then the punching mechanism is pushed out of the cartridge by the penetrating mechanism to make the hole penetrate the earlobe to make a hole, and further synchronized with the penetrating mechanism. The piercing hole penetrating the earlobe is removed by the removal mechanism that operates to remove only the thin tube leaving the piercing hole protective device in the hole. Therefore, the piercing operation of the hole opening device to the desired position of the earlobe and the thin tube from the earlobe Can be quickly and easily performed with a uniform flow.

The earlobe holding mechanism is disposed below the hole-piercing tool and parallel to the axis of the hole-piercing tool, and is capable of translating in the direction parallel to the axis of the hole-piercing tool with respect to the apparatus body. An earlobe holding lever composed of a transparent flat earlobe holding plate fixed to the tip of the shaft perpendicular to the longitudinal direction thereof, and a rubber ring that press-fits the shaft of the earlobe holding lever. A rubber member which is a plate-shaped member disposed on a shaft portion of the earlobe holding lever, closer to the earlobe holding plate than the rubber ring, and perpendicular to a longitudinal direction thereof so as not to contact the shaft portion; And a stop member capable of stopping the movement of the earlobe holding lever against the movement of the earlobe holding lever.

In this case, when the earlobe holding lever is pushed to hold down the earlobe, the movement of the rubber ring is restricted by the stop member, so that a frictional force is generated between the shaft of the earlobe holding lever and the rubber ring. Works. If the outer diameter of the shaft portion and the inner diameter of the rubber ring are designed so that the magnitude of the frictional force is sufficiently larger than the repulsive force that the earlobe holding lever receives from the earlobe when the earlobe is held down, the earlobe holding The lever can be stably stopped while holding down the earlobe with a constant force. Therefore, the earlobe can be fixed at the time of penetration, and it becomes easy to aim the tip of the hole punch at a desired position of the earlobe. Further, when the earlobe holding plate is made of a transparent material, the earlobe can be viewed from a direction perpendicular to the surface of the earlobe, so that the position of the hole can be easily aimed.

The stop member includes a pushing rod for pushing the hole punch from its rear end, and has a support hole through which a shaft of an earlobe holding lever is inserted. It can be integrally molded as a part.

In this case, when the penetrating mechanism is operated, the rubber ring is pushed by a stop member integrated with the pushing rod, and the earlobe holding lever causes the earlobe to be moved by the frictional force between the shaft portion and the rubber ring. Receives biasing force in the pushing direction. As a result, the earlobe is pierced while being further pressed, so that a more stable piercing operation can be performed.

[0013] The removing mechanism is provided at a tip end side of the drilling tool, and is supported along the axial direction of the drilling tool so as to approach and separate from the drilling tool. A gripping member that is detachably provided on the arm, and that grips the hole punching tool by inserting the hole punching tool from the tip when the arm approaches the hole punching tool.

In this case, since the holding member holding the thin tube can be removed from the arm, the operation of removing the thin tube can be simplified by disposing the holding member as a disposable. In addition, since the dirty tubule after penetrating the earlobe can be disposed of without directly touching it, the operation can be performed extremely hygienically and safely.

In the cartridge, the pair of guide members pushed into the through-hole together with the hole-piercing member are locked inside the through-hole, and the pair of guide members are held until the penetration of the earlobe by the hole-piercing member is completed. A locking claw portion to be retained inside the through hole can be provided.

In this case, both guide members of the cartridge remain in the cartridge until the penetration of the earlobe by the hole-piercing device is completed, and after the penetration of the earlobe is completed, the guide members are pushed by the flange portion of the piercing hole protective device and the cartridge. The hole punch is pushed out of the ear lobe, and is reliably supported by the needle guide until the penetration of the earlobe is completed, so that it is difficult for the pushing direction to be out of order, so that the earlobe can be accurately penetrated to a desired position.

Further, the gripping member has a plate-like portion arranged substantially perpendicular to the hole-piercing device, and the plate-like portion has a radial shape centered on a position where the hole-piercing device is inserted. A structure in which a plurality of leaf spring portions are provided by forming a cut, and the leaf spring portion is bent in a conical shape protruding from the center of the cut as an apex toward a direction in which a hole punch is inserted. Can be

In this case, when inserting the hole punch into the plate-like portion, the thin tube is inserted with low resistance because the leaf spring portion is pushed outward, but when removing only the thin tube from the hole punch, The leaf spring part bent in a conical shape plays the role of a barb, and the leaf spring part also helps friction with the surface of the thin tube and tightens inward because it tightens inward. And the tubule can be reliably removed from the earlobe.

The piercing hole protector is a tube-type member having a small-diameter hole portion that can be supported by inserting the shaft portion of the decorative piercing from one end into the rod-shaped portion. Can be used. In this case, it is effective if the member is made of a material that does not cause metal allergy. If the member is made of an inflexible material, use a protective device for a pierced hole whose rod-shaped portion is shorter than the shaft portion of a normal pierce, and apply a metal allergy to the portion of the shaft portion that has penetrated from the rod-shaped portion. The piercing can be held by fitting with a fastener made of a material that does not cause piercing. In this case, even a flexible pierce, for example, made of resin, can be used by being inserted into the hole of the pierced hole protector. At this time, since the piercing is made of a soft material, it is difficult to be broken and is safe. Also, since the tip of the piercing does not need to be sharp, there is no fear of damaging the skin. Furthermore, 1
You can enjoy wearing earrings without any metal allergy.

On the other hand, when the member is made of a material having flexibility, a protective member for a pierced hole whose rod-shaped portion is longer than a shaft portion of a normal pierce is used. When the shaft of the decorative piercing is pushed into the small-diameter hole of the rod, the rod is pushed out by the shaft of the piercing, and the piercing can be held by the restoring force.

The cartridge 60 has a needle guide 70
At the same time, with the piercing device 3 loaded, the piercing device 3 is placed in a heated gas such as ethylene oxide gas for a certain period of time and gas sterilized.

Next, the use and operation of the piercing device 10 constructed as described above will be described with reference to FIGS.
This will be described with reference to FIG. Although the hole punch 3 in the cartridge 60 is not originally visible from the outside of the cartridge 60 as shown by a dotted line in FIG. 9, for convenience of explanation, its position is not shown in FIG. It is drawn with a solid line as you can see.

First, as shown in FIG. 9, the cartridge 60 loaded with the hole punch 3 is mounted on the casing 12 and the piercing device 10 is brought close to the earlobe A. I do.

Subsequently, as shown in FIG. 10, the earlobe holding lever 91 is pushed into the inside of the casing 12, and
As shown in FIG. 1, the earlobe A is held down by the earlobe holding plate 91b at the tip of the earlobe holding lever 91. The earlobe holding lever 91 is

2 is prevented from moving with excessive momentum, it is possible to slowly and safely hold down the earlobe, and at a position where the earlobe A is sufficiently pressed, a certain force is applied. It is possible to stop while holding down the earlobe.

Next, the operating portion 21 of the penetrating lever 25 is held, and the penetrating lever 2 is pressed against the elastic force of the rod spring 30.
5, the pushing rod 23 is
2 and penetrates the inside of the cartridge 60, and starts pushing out the hole punch 3 together with the thin tube 4. At this time, if the elastic force of the rod spring 30 is appropriately large, the rod spring 30 can be delicately moved, and can more accurately penetrate the target position.

When the insertion is continued, the hole punch 3 is completely discharged from the cartridge 60 and penetrates the earlobe A.
Then, as shown in FIG. 12, the hole-piercing tool 3 penetrating the earlobe A is in a state of being gripped by the gripping mechanism 50.

When the insertion is further continued, the release rod 22
Starts pushing the arm 80c of the stopper 80. When the arm portion 80c is further pushed, the stopper 80 rotates about the support hole 80b as a fulcrum against the elastic force of the stopper spring 81, as shown in FIG. From the concave portion 41c. As a result, the arm 41 translates in a direction away from the earlobe A by the elastic force urged by the arm spring 42, and at this time, the thin tube 4 gripped by the gripping mechanism 50 from the earlobe. Removal is complete.

By the way, as shown in FIG. 14A, the hole-piercing device 3 and the needle guide 70 initially connect the flange 2b of the piercing hole protector 2 (see FIGS. 17 and 18) to the cartridge 60.
The needle guide 70 sandwiching the tip of the hole punch 3 is placed in the opening of the cartridge 60 and is loaded inside the cartridge 60. In this state, when the push-out of the punch 3 by the pushing rod 23 of the penetrating mechanism 20 is started, first, the needle guide 70 stays inside the cartridge 60 as shown in FIG. Only one is pushed out along the grooves 71d, 72d and penetrates the earlobe. The hole-piercing tool 3 is further pushed out, and the flange portion 2b of the piercing hole protective tool 2 is
14C, the needle guide 70 is pushed out together with the hole punch 3 as shown in FIG. When the needle guide 70 is completely discharged from the cartridge 60, the guide members 71 and 72 are naturally separated by their own weight as shown in FIG.

According to the piercing device thus constructed, the earlobe is held down by the earlobe holding mechanism, the hole punch is pierced to the target position of the earlobe by the piercing mechanism, and the piercing device is removed from the earlobe by the removing mechanism. Capillary removal can be performed. Further, since the penetration mechanism and the removal mechanism operate in synchronization with each other, it is possible to quickly and easily carry out the penetration of the perforator into the earlobe and the removal of the thin tube from the earlobe.

In addition, in the needle guide 70 that locks the hole punch 3 inside the cartridge 60, the cross-sectional shape of the grooves 71d and 72d in which the hole punch 3 is arranged is V-shaped, and The contact area between the needle guide 70 and the needle guide 70 is small, and when the punch 3 is pushed out of the cartridge 60, the frictional resistance between the needle guide 70 pushed into the through hole 63 and the cartridge 60 indicates that the needle 3 and the needle Since it is superior to the frictional resistance with the guide 70, only the punch 3 can be pushed out while the needle guide 70 is kept inside the cartridge 60.

The projections 73 and the recesses 74 respectively provided on the guide members 71 and 72 are engaged with each other, so that the guide members 71 and 72 are provided inside the cartridge 60.
72 can be moved together, and both can be simultaneously ejected from the cartridge 60.

In addition, the guide members 71 and 72 move inside the cartridge 60 integrally by the engagement of the projections 73 and the recesses 74, but the wall surfaces 71b and 72b
Are separated from each other, and the guide members 71 and 72 are not in direct contact with each other, so that the guide members 71 and 72 are easily separated when discharged from the cartridge 60.

When the hole-piercing tool 3 penetrating the earlobe reaches the removing mechanism 40, as shown in FIG. 15A, the tip of the hole-piercing tool 3 opposes the elastic force of the leaf spring 58e. 58d, and are clamped from the surroundings by the respective leaf spring portions 58e to be gripped.

Thereafter, when the arm 41 moves in a direction away from the earlobe placement section 14 by the elastic force of the contracted rod spring 30, as shown in FIG. 15 (b), the holding member 58 becomes elastic with the leaf spring section 58e. The capillaries 4 are separated from the earlobe while holding the capillaries 4 by force, and only the capillaries 4 are removed from the earlobe.

Finally, the gripping member 58 is detached from the arm 41 while holding the thin tube 4 and is disposable, and a new gripping member 58 is attached to the arm 41.

According to the piercing device constructed as described above, since each leaf spring portion 58e is bent in a conical shape in the direction in which the piercing device 3 is inserted, the piercing device 3 is formed.
Is inserted into the plate-shaped portion 58a, the hole spring 3 is inserted with low resistance because the leaf spring portion 58e is pushed outward. When only the thin tube 4 is removed from the hole-piercing tool 3, the force generated between the earlobe and the thin tube 4 causes the thin tube 4 to be pulled out from the plate-like portion 58 a, but the tube is bent in a conical shape. While the leaf spring portion 58e plays a role of a barb, the friction with the surface of the thin tube 4 also helps, and the leaf spring portion 58e is tightened inward, so that the thin tube 4 is gripped with a stronger force. Is prevented, and the thin tube 4 can be reliably removed from the earlobe.

Further, since the holding member 58 can be removed from the arm 41 while holding the thin tube 4,
Since the gripping member 58 is disposable, the operation of removing the thin tube 4 can be simplified.

Further, the thin tube 4 held by the holding member 58
Is covered with the covering member 59, the sharp tip of the thin tube 4 is not exposed to the outside, and there is no danger of injury due to the thin tube 4 even after the gripping member 58 is removed from the arm 41. It can be implemented safely.

The shape of the gripping member 58 described above is merely an example, and the specification may be changed as appropriate without departing from the scope of the present invention. For example, the number of leaf springs is not limited to four, and a plurality of leaf springs may be radially provided. The holding member 58 may have various shapes as shown in FIG. The gripping member 58 shown in FIG. 16A is obtained by insert-molding a part of the resin forming the tubular covering member 59 into a plurality of small holes provided in the plate-shaped portion 58a.
The cover member 59 is fixed to a. FIG. 16 (b)
The gripping member 58 shown in FIG. 1 does not include a resin covering member, but is formed by bending a single stamped metal plate and integrally providing a covering portion 59 ′ covering the thin tube 4 and a plate-like portion 58a. It is.

Extruded from. When the needle guide 70 is completely discharged from the cartridge 60, the pair of guide members 71 and 72 are naturally separated by their own weight as shown in FIG.

According to the piercing device 10 constructed as described above, the needle guide 70 is temporarily locked inside the cartridge 60 by the locking claw portion 64, and
Only the extruded material is pushed out, and the hole guide 3 is securely supported by the needle guide 70 until the penetration of the earlobe is completed, so that it is difficult for the pushing direction to be deviated, so that it is possible to accurately penetrate the earlobe at a desired position. .

Next, a third embodiment of the piercing apparatus according to the present invention will be described with reference to FIG. The components already described in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The piercing device in this embodiment is
The configuration of the piercing hole protection device is different from that of the first or second embodiment. The protective device for piercing holes in the first or second embodiment is a straight rod-shaped member made of resin. However, in this embodiment, a material that does not cause metal allergy, for example, a fluorine-containing resin, ceramic,
A tube type having a hollow portion made of titanium or the like is used.

First, a thin tube (not shown) is pierced from one side of the earlobe A using the piercing device of the first or second embodiment, and then the piercing hole protection device of the present embodiment is used. The tool 100 is pushed in until the flange portion 100b contacts the earlobe A, and then only the thin tube is pulled out from the other surface side of the earlobe A, leaving the earring protective device 100 in the earlobe. Next, a general pierce 101 is inserted into the protector hole 100c of the pierce hole protector 100. When the pierce hole protector 100 is made of a resin having no flexibility such as polypropylene, for example, FIG. As shown in (a), a resin fastener 1 that fits a post portion 101b of a piercing 101 and a rod-shaped portion 100d of a piercing hole protector 100.
02 is used to hold the piercing 101. When the piercing hole protector 100 is made of a flexible resin such as Lavalon, for example, the inner diameter of the protector hole 100c of the piercing hole protector 100 is made smaller than the outer diameter of the post portion 101b of the piercing 101. If the post part 101b is pushed into the protection tool hole 100c, the protection tool hole 100c is expanded by the post part 101b, and the post part 101b is firmly held inside by the restoring force. Therefore, the fastener of the earring itself is unnecessary.
Further, although the piercing hole protective device 100 is held in the hole of the earlobe A without any particular fastener, as shown in FIG.
It is sufficient to use a fastener 102 that can be fitted only to the bar-shaped portion 100d of the 00. Note that, in the drawing, the state where the pierced earrings are used is shown by a two-dot chain line.

In this case, since the piercing hole protection device is 100% free of metal allergy, the user can enjoy wearing the piercings from the moment when the earlobe is opened. Also,
When using the metal fastener attached to the general piercing, prepare a resin washer and attach the washer between the earlobe and the fastener so that the metal fastener and the earlobe come into direct contact Because it does not, metal allergy can be prevented.

As described in detail above, the piercing apparatus according to the present invention has the following effects.

According to the piercing device according to the first aspect, the earlobe is pressed by the earlobe pressing mechanism to aim at a desired position, and then the punching device is pushed out of the cartridge by the penetrating mechanism to pierce the earlobe. By removing the pierced hole from the hole-piercing tool that has penetrated the earlobe and removing only the thin tube by leaving the pierced-hole protector in the hole, the desired position of the earlobe The operation of penetrating the hole punching device and the operation of removing the thin tube from the earlobe can be quickly and easily performed with a unified flow.

[0068] Further, earlobe pressing lever by frictional resistance acting between the shaft portion and the rubber ring earlobe pressing lever can be stopped stably remains that pressing down with a constant force the earlobe. Therefore, since the earlobe does not move in the earlobe arrangement portion during the penetration process, it is easy to aim the tip of the hole punch at a desired position of the earlobe. Further, when the earlobe holding lever moves against the frictional force, the frictional force prevents the earlobe holding lever from moving with excessive momentum, and the earlobe holding operation can be performed slowly and safely. Further, when the earlobe holding plate is made of a transparent material, the earlobe can be viewed from a direction perpendicular to the surface of the earlobe, so that the position of the hole can be easily aimed.

[0069] According to piercing punching device according to claim 2, stop member, because they are integrally molded as part of the piercing lever and press the piercing lever, rubber ring, together with the piercing lever, The penetrating lever is moved by being pushed by the periphery of the hole through which the shaft of the earlobe pressing lever is inserted. At this time, the earlobe holding lever receives a biasing force in the direction of pressing the earlobe due to the frictional force between the shaft portion and the rubber ring, so that the earlobe is pierced in a further pressed state, and the hole at that time is pressed. The tip of the tubing of the opener is less likely to shake. That is, in this case, the penetration and the pressing of the earlobe at that time can be performed by an integrated operation due to the presence of the rubber ring on the shaft of the earlobe holding lever.

According to the piercing device according to the third aspect , the holding member is detachably provided on the arm, and the holding member holding the thin tube can be removed from the arm. The operation of removing the thin tube can be simplified by disposing the gripping member. In addition, since the dirty tubule after penetrating the earlobe can be disposed of without directly touching it, the operation can be performed extremely hygienically.

According to the piercing device according to the fourth aspect , the cartridge has a locking claw portion for locking a pair of guide members to be pushed into the through hole together with the punching device in the pushing direction of the punching device. Are provided corresponding to both guide members, and both guide members remain in the cartridge until the penetration of the earlobe by the hole-piercing tool is completed, and after the penetration of the earlobe is completed, the flange portion of the protective device for the piercing hole is provided. The cartridge is pushed out of the cartridge, and the hole guide is securely supported by the needle guide until the penetration of the earlobe is completed. It becomes possible.

According to the piercing device according to the fifth aspect , each leaf spring portion is bent in a conical shape in a direction in which the hole-piercing tool is inserted, and when the hole-piercing device is inserted into the plate-shaped portion. In this case, the thin tube is inserted with low resistance because the plate spring portion is pushed outward, but when removing only the thin tube from the hole punch, the plate spring portion bent in a conical shape plays the role of a barb. In addition, the force of gripping the thin tube is enhanced because the leaf spring portion also tightens inward due to friction with the surface of the thin tube, so that the thin tube is prevented from coming off from the gripping member, and the thin tube can be reliably removed from the earlobe.

According to the piercing device according to the sixth aspect , even a flexible piercing material, for example, made of resin, can be used by being inserted into the hole of the piercing protection device. In addition, if a material that does not cause metal allergy is used for the pierced hole protection device and the fastener, a general pierced earring can be worn and enjoyed from the moment the hole is opened.
