A fastener with a locking mechanism according to a preferred embodiment of the present invention (hereinafter, also referred to as the present fastener) will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of the present fastener before locking. As shown in FIG. 1, the fastener includes a female hook 1 and a male hook 2. The female hook 1 and the male hook 2 are made of a base material 14 (back side base material) and a base material 15 (front side base material) such as clothing, bag products, nursing care products, fabrics of other products, leather, plastics, etc. By attaching the dowels 10 of the male hooks 2 to the lock portions of the female hooks 1 and attaching them in pairs to the respective desired attachment locations, the binding and locking are performed simultaneously. Then, when the locked main fastener is unlocked by a desired unlocking tool or a magnetic key, the female hook 1 and the male hook can be detached and removed.

The male hook 2 and female hook 1 of the fastener will be described with reference to exploded views of FIGS. 11 and 12.
The male hook 2 of the fastener of this example is basically composed of a dowel 10, a spring 30, a knock bar 31, an inner ring 32, and an outer lid case 33.
The dowel 10 has a columnar portion planted on a pedestal 34, and a through hole 21 is provided in the center of these dowels 10 in the attaching / detaching direction. The columnar portion of the dowel 10 is formed with a groove 13 for locking a hook of a female hook, which will be described later, on the outer periphery, and has a tapered push-in portion 12 above the groove 13. The pushing portion 12 has a smooth inclined surface toward the tip. As shown in FIG. 11, the male hook 2 is attached by inserting the dowel 10 into the attachment hole formed in the base material 15, covering the fitting 9 from the dowel pushing portion 12 side, and caulking the fitting piece. Done.

The knock bar 31 is inserted into the through hole 21 of the dowel 10 via a spring 30 on the outer periphery in the axial direction, and the knock bar 31 is disposed so as to move forward and backward in the through hole 21. . That is, as shown in FIG. 11, the through hole 21 of the dowel 10 is formed with a cylindrical enlarged portion having an enlarged inner diameter between the front end side and the rear end side. In the said enlarged diameter part, it is arrange | positioned on the outer periphery of the knock bar 31 and along the axial direction. A first locking portion 35 (see FIG. 1) for locking the front end (the upper end side in FIG. 11) of the spring 30 is provided at the distal end portion of the enlarged diameter portion of the through hole 21 of the dowel 10. On the other hand, the rear end portion 36 of the knock bar 31 is provided with a second locking portion 37 that locks the rear end of the spring 30, and the second locking portion 37 is an opening formed in the exterior case 33, for example. Retraction of the knock bar 31 is restricted by the inner peripheral edge of the portion 38. When the tip of the knock bar 31 moves forward in the direction protruding from the through hole 21, a biasing force is applied to the spring 30 by the first locking portion 35 and the second locking portion 37. With such a configuration, the rear end portion 36 of the knock bar 31 is pushed by a desired unlocking tool, the knock bar 31 moves forward, and moves forward in the direction in which the tip of the knock bar 31 protrudes from the opening of the through hole 21. At this time, the drive piece of the female hook 1 is pushed up and unlocked. On the other hand, when the unlocking tool is removed from the rear end portion of the knock bar, the knock bar is retracted by releasing the urging force of the spring 30.
The material of the dowel 10 is not particularly limited, but is preferably a metal such as brass or stainless steel, a high-strength plastic, or the like.

  On the other hand, the female hook 1 is configured by incorporating an inner case 7 and a lid case 8, and a lock portion is formed between the inner case 7 and the lid case 8. As shown in FIGS. 1 and 12, the inner case 7 is a substantially donut-shaped body having a space portion for incorporating a lock portion therein, and a through hole 26 for inserting and removing the dowel 10 of the male hook 2 at the bottom. Is provided with a diameter larger than the maximum diameter of the columnar portion of the dowel 10. The lid case 8 is a circular cap-shaped body that is crowned by the inner case 7 of the female hook 1. In the case of a fastener that is unlocked by bringing the magnet key close to or in contact with the front side of the lid case 8, the front side of the lid case 8 makes the magnet key close to or easy to contact when unlocked. Therefore, it is preferable to be substantially flat.

  The lock portion of the female hook 1 includes a hook 3 that is locked to the dowel 10 of the male hook 2, a guide 5 that holds the hook 3, and a drive portion that releases the lock of the hook 3 with respect to the dowel 10 of the male hook 2. It has a piece 4 and a spring 6 that urges the hook into a locked state. The drive part piece 4 of this example is a substantially truncated cone having a hollow part 25 into which the pushing part 12 of the male hook 2 can be inserted from below. In the case of a fastener that is unlocked by bringing a magnetic key close to or in contact with the front side of the female hook, this drive piece 4 is made of stainless steel other than iron or 18-8 stainless steel (magnetic stainless steel). Formed of magnetic material. In particular, magnetic stainless steel is excellent in rust prevention and is economically preferable. By forming the drive part piece 4 from a magnetic material, the drive part piece 4 can be operated by the magnetic force of the magnet key during unlocking to release the hook 3 from the dowel 10. The drive piece 4 is usually made entirely of a magnetic material, but only the top of the hollow body where the magnetic force acts most when unlocking may be made of a magnetic material, or a magnetic material may be adhered to this portion. Good.

  The hook 3 has a locking portion 16 for locking the female hook 1 to the dowel 10 of the male hook 2 when the fastener is locked. The hook 3 of this example is formed of a U-shaped member having an inner leg piece and an outer leg piece as shown in the figure, and the locking leg 16 is formed by bending the tip of the inner leg piece outward. The inner leg piece of the U-shaped member has elasticity, and can be elastically deformed when the locking portion 16 is pushed by the pushing portion 12 of the dowel 10 of the male hook 2 in the locking process. In order to securely and stably attach and lock the hook, normally, four hooks are used around the drive piece as in this example, but the number of hooks is not limited. Or three of them may be arranged at equal intervals around the drive unit piece.

  The above example is a book fastener of the type having a hook on which a dowel of a male hook is locked and a spring member that biases the hook in a locked state, and the dowel of the male hook is engaged with the hook of the female hook. The female hook and the male hook are bound to each other by being stopped, and the driving part piece to which the dowel of the male hook is locked and the spring for biasing the driving part piece in a locked state In this type of fastener having a member, the dowel of the male hook may be engaged with the drive part of the female hook so that the female hook and the male hook are bound. For example, a locking projection is provided in the vicinity of the lower end on the inner side of the hollow portion of the drive unit piece, a locking recess that is engaged with the locking unit is provided on the outer periphery of the pushing portion of the male hook tab, and the drive unit piece The female hook and the male hook may be bound by engaging the latching convex portion with the latching concave portion of the male hook tab.

  In order to incorporate the inner case 7 and the lid case 8 in order to form the lock portion, four hooks 3 are placed on the outer side of the drive piece 4 as shown in FIGS. Then, the guide 5 is mounted on the hook 3 from above after the lower end of the drive piece 4 is placed in the space portion of the inner case with the lower end of the drive piece 4 placed on the locking portion 16. Alternatively, the guide 5 is mounted on the hook 3 and then assembled. As shown in FIG. 12, the guide 5 has a notch 24 for holding the hook 3, and the hook 3 is incorporated into the notch 24 and held. In a state where the hook 3 is incorporated in the notch portion 24, the outer leg piece of the hook 3 is held by the guide 5, and the inner leg piece is disposed along the outer surface of the drive part piece 4. Further, the inner side of the guide 5 except for the notch 24 is in contact with the outer surface of the drive piece 4. The maximum diameter of the guide 5 is smaller than the diameter of the space portion of the inner case so that the guide 5 can move up and down in the space portion of the inner case.

  Thus, after holding the hook 3 on the outer side of the drive piece 4 with the guide 5 and receiving it in the inner case 7, the spring 6 is urged against the guide 5 to cover the lid case 8. In this example, a coil spring is used as the spring 6. However, the present invention is not limited to this, and for example, a leaf spring, a bamboo spring, a spiral spring, a wire spring, or the like can be used. Further, the shape and size are appropriately determined according to the shape of the guide 5. In the case of the form of a fastener that unlocks by bringing the magnet key close to or in contact with the front side of the female hook, the spring 6 has an elasticity smaller than the magnetic force of the magnet key that acts on the drive piece 4 at the time of unlocking. Powerful ones are used.

  In the case of a fastener that is unlocked by bringing a magnetic key close to or in contact with the front side of the female hook, the female hook 1 of the present invention may be formed of a nonmagnetic material for members other than the drive piece 4. preferable. In particular, the lid case 8 is preferably a nonmagnetic material. The reason is that when the magnet key is brought close to the female hook 1 at the time of unlocking, the magnetic force concentrates on the drive member piece 4 of the magnetic material and does not act on these members. As this nonmagnetic material, for example, metals such as 18-8 stainless steel, brass, zinc, and aluminum are preferable in terms of strength, rust prevention, ease of manufacturing, and the like, and brass is particularly excellent. In addition, when it is not an above-described form, the material which comprises the cover case 8 is not restricted to the above-mentioned nonmagnetic material, A magnetic metal material may be sufficient.

  In order to attach the female hook 1 to the base material 14 such as a clothing product, a bag product, or a care product, a hole is made in a desired portion of the base material 14 to which the female hook 1 is attached, and the hole is fitted to the hole from the back side. 9 (see FIG. 12) is inserted, and the inner case 7 of the female hook 1 in which a lock portion is formed is fitted to the end piece 22, and the front portion of the end piece 22 and the inner case 7 are fitted. And it can carry out by bending together in the state which overlapped with the edge of lid case 8. FIG. In this case, if the projections 23 are formed on the eyelets 9, the projections 23 can bite into the base material and can be firmly attached. The attachment method of the female hook 1 can be appropriately selected depending on, for example, the type of clothes to be attached, the type of clothes base material, and the like, and is not limited. For example, in this example, the female hook 1 incorporating the lock portion is attached to the base material 14 with the fit 9. However, the fit 9 is inserted into the base material 14 in advance, and the inner case is fitted into the fit 9. In combination, a female hook may be attached.

  FIG. 1 shows a female hook 1 before locking, which is attached to a base material 14 such as a clothing product, a bag product, or a care product. In FIG. 1, the two hooks 3 arranged on the outer side of the drive unit piece 4 are supported by the outer surface of the drive unit piece 4 whose inner leg piece is substantially frustoconical and the outer leg piece is held by the guide 5. The leading end of the locking portion 16 of each hook 3 protrudes inside the drive piece 4. Since the guide 5 is pushed downward by the bias of the spring 6, the hook 3 and the drive piece 4 in the normal state are both pushed down and held by the elastic force of the spring 6 through the guide 5.

With respect to the drive part piece 4 in this state, the unlocking tool 39 is pressed from the outside to the knock bar 31 accommodated in the through-hole 21 from the outside of the male hook 2, and the unlocking tool 39 is moved inside the through-hole 21. As it advances, the guide 5 is pushed up against the elastic force of the spring 6 by the outer surface of the substantially truncated cone shape of the drive piece 4.
Further, when a magnetic force is applied to the driving part piece 4 in this state from the outside (the lid case side) of the female hook 1 by a magnet key, the driving part piece 4 is formed of a magnetic material, and thus the driving part piece 4 Is attracted upward by a magnetic force, and pushes up the guide 5 against the elastic force of the spring 6 on the outer surface of the truncated cone shape.
When the guide 5 is pushed up, the restraining of the hook 3 against the outer leg piece is eliminated, and the inner leg piece is pushed by the driving part piece 4 so that the hook 3 moves outward. The locking portion 16 that protruded to the back is retracted. Then, when the pressing force of the knock bar or the magnetic force acting on the drive piece 4 is eliminated, the hook 3 and the drive piece 4 are pushed down by the urging force of the spring 6 acting on the guide 5 and return to the initial position. .

Next, the locking process of the fastener will be described with reference to FIGS.
As shown in FIG. 2, when the dowel 10 of the male hook 1 is inserted into the hollow part 25 of the drive part 4 of the female hook 1, the inclined surface of the tapered pushing part 12 protrudes inside the drive part 4. 3 is engaged with the locking portion 16. When the dowel 10 is further pushed in, the inner leg piece of the hook 3 is elastically deformed in the direction of the arrow as shown in FIG. 2A, and the locking portion 16 is pushed outward by the inclined surface of the pushing portion 12.

  When the dowel 10 is completely pushed into the hollow portion 25 of the drive piece 4, as shown in FIG. 3, the locking portion 16 of the hook 3 is inserted into the groove 13 provided in the dowel 10 and the hook 3 (inner leg piece). Fit with the elastic restoring force. As a result, the female hook 1 and the male hook 2 are bound, and at the same time, the dowel 10 is locked to the hook 3 and is locked because it cannot be removed. In the locked hook, the hook 3 is pressed by the guide 5 by the bias of the spring 6, so that the locking between the locking portion 16 and the groove 13 of the dowel 10 is securely held. As a result, the locked main fastener cannot be detached unless it is unlocked by intentionally moving the drive piece 4 with the unlocking tool or the magnetic key to release the hook 3 and is not unlocked. .

Next, the unlocking tool 39 is pressed against the knock bar 31 accommodated in the through hole 21 from the outside of the male hook 2, and the unlocking tool 39 is advanced through the through hole 21 to release the fastener of this example. The case of locking will be described with reference to FIGS.
As described above, the female hook 1 and the male hook 2 locked as shown in FIG. 4 are disposed behind the knock bar 31 inserted into the through hole 21 provided in the male hook 2 as shown in FIGS. The unlocking tool 39 is pressed against the end portion 36, the unlocking tool 39 is advanced, the tip end portion of the knock bar 31 is brought into contact with the driving part piece 4, and the driving part piece 4 is moved to the spring member by the advancement of the knocking bar 31. 6 (when the knock bar 31 is pushed upward in FIG. 5), the drive piece 4 rises, and the inclined surface (outer surface) pushes the guide 5 outward while lifting up. At the same time, since the hook 3 is moved outward (in the direction of the arrow), the locking portion 16 of the hook 3 is released from the groove 13 of the dowel 10 and the locking is released, so that the fastener is unlocked. As the knock bar 31 advances, the spring 30 is contracted, and an urging force is generated. When the unlocking tool 39 is released from the rear end of the knock bar 31 after the fastener is unlocked, the urging force of the spring 30 is released, and the knock bar 31 retracts and returns to the original position. The locked state is maintained. Then, as shown in FIG. 7, the female hook 1 and the male hook 2 are separated.
When unlocking the fastener of the present invention, it is not necessary to use an unlocking device having a specific structure designed for unlocking the fastener, and from the front side of the male hook of the fastener (that is, the clothing product). Can be used as an unlocking tool such as a ballpoint pen.

Next, referring to FIGS. 8 to 10 for the case of unlocking using the magnetic key from the outside of the female hook 1 (that is, from the back side of the garment in the clothing product) of the fastener with the locking mechanism of this example. To explain.
As shown in FIG. 8, unlocking of the locked main fastener is performed by bringing a magnetic key closer to the female hook 1. As shown in FIG. 8, when the magnet 19 of the magnet key is brought close to the female hook 1, the drive unit piece 4 formed of a magnetic body is attracted to the magnet 19 and moves upward. When the drive piece 4 is raised, the inclined surface (outer surface) pushes the guide 5 outward while lifting the guide 5 and simultaneously moves the hook 3 outward (arrow direction). The latch is released from the groove 13 and the fastener is unlocked.

  FIG. 9 shows the state of the female hook and the male hook immediately after unlocking. When the magnet 19 is separated from the female hook 1, the drive piece 4 and the hook 3 are about to return to the original positions via the guide 5 by the spring 6. At this time, the female hook 1 and the male hook 2 are also uncoupled at the same time as being unlocked, and are about to be separated from each other by the bending force of the base materials 14 and 15. Even after the magnet 12 is released from the fastener, the unlocking state can be maintained. At the same time, the binding is released. Further, since the hook 3 indirectly returns following the operation of the drive piece 4, the locking portion 16 of the hook 3 easily shifts upward from the groove 13 of the dowel 10 and remains detached from the groove 13. It becomes a state. Thereby, it is possible to remove the female hook and the male hook without pulling them apart using both hands in the unlocked state like a conventional magnetic hook. In this case, if a slight gap is provided between the hook 3 and the lid case 8 in the state before unlocking, the hook 3 is moved upward by the drive piece 4 at the time of unlocking. When returning to the original position, it is preferable because the locking portion 16 is more easily detached from the groove 13 of the dowel 10.

  FIG. 10 shows a state in which the fastener is completely unlocked. In this state, the drive piece 4 is attracted upward by the magnet 19 and the hook 3 is retracted to both sides, so that the female hook 1 and the male hook 2 are separated by the bending and weight of the base materials 14 and 15. The fastener can be easily removed. When the magnet 19 is separated from the female hook 1 after the fastener is removed, the pulling of the drive piece 4 due to the magnetic force is eliminated, so that the hook 3 and the drive piece 4 are moved by the biasing force of the spring 6 as described above. Return to the original state.

  As the unlocking tool of the fastener with a locking mechanism according to the present invention, as described above, the unlocking tool is configured to be unlocked by the action of the knocking bar interposed with the spring, so that the rear end portion of the knocking bar with which the unlocking tool abuts.
