Next, the present invention will be specifically described with reference to the drawings. The drawings illustrate preferred embodiments of the invention, and the invention is not limited to the drawings and description thereof. In addition, parts having the same function in the drawings will be described with the same reference numerals for easy understanding.
FIG. 1 is a cross-sectional view showing a state in which a female hook 1 and a male hook 2 are fitted, which is one preferred embodiment of the fastener according to the present invention. The female hook 1 has a locking member 3, the male hook has a hook portion 4, and the hook portion 4 is locked by the locking member 3 so that the female hook 1 and the male hook 2 are not detached. It has come to be.
The female hook 1 includes an inner case 7 and an outer case 8 that are attached to a base material 6 such as a bag product, a clothing product, or a care product by a retaining rod 5, and between the inner case 7 and the outer case 8. Further, the locking member 3, the stopper portion 9 and the spring member 10 are incorporated, and the locking member 3 engaged with the male hook 2 is locked by the stopper portion 9 so that the locking is not released. The stopper portion 9 is biased by the spring member 10.
On the other hand, the male hook 2 is attached to the base material 6 with the base material 6 sandwiched between the pedestals 27 and 29, and the hook portion 4 is fixed to a cylindrical portion formed at the center of the hook portion 4. The pins 11 are integrated by inserting them.
FIG. 2 is a schematic plan view from the front side of the female hook 1, where 5 is a retaining rod, 12 in the circular opening in the central region of the retaining portion 5 is the top of the inner case 7, and 14 is the corresponding portion. The tangent is shown. FIG. 3 is a plan view of the outer case 8.

Next, the female hook 1 will be described in detail with reference to FIG. 4 which is an exploded view showing a schematic configuration thereof. 4, (a) is the outer case 8, (b) is the elastic ring 22 of the specific example of the locking member 3, (c) is the spring member 10, (d) is the stopper portion 9, (e). ) Shows the inner case 7, and (f) shows the retaining rod 5, each drawing on the left shows a schematic perspective view, and each drawing on the right shows a schematic skeleton of each cross section. FIG.
The stopper portion 9 of this example is formed in a substantially truncated cone shape or a substantially cylindrical shape having a diameter similar to the ring shape of the locking member 3 so that the locking member 3 can be accommodated therein. A rotation operation unit 36 is formed on the top plate portion 24 having a trapezoidal shape or a substantially cylindrical shape. In addition, a receiving portion 23 is provided along the inner circumferential direction on the skirt side of the substantially truncated cone shape or the substantially cylindrical shape. As described above, when the receiving portion 23 of the elastic ring 22 is provided in the stopper portion 9, the elastic ring 22 can be reliably locked by the stopper portion 9.
In the present invention, the stopper portion 9 is made of a magnetic material. By forming the stopper portion 9 from a magnetic material, the stopper portion 9 that locks the locking member 3 is moved upward by the magnetic force of the magnet to release the locking, and the female hook 1 is removed from the male hook 2. Can do. Examples of the magnetic material suitable for the stopper portion 9 include iron and stainless steel other than 18-8 stainless steel (hereinafter referred to as magnetic stainless steel). Among these, magnetic stainless steel is excellent in rust prevention and is economically preferable. The stopper portion 9 is generally formed entirely of a magnetic material, but the stopper portion 9 main body may be formed of a non-magnetic material, and the magnetic material may be provided, for example, by bonding to a portion that easily receives the magnetic force.
As shown in FIG. 4, the outer case 8 is a cap-like body having a peripheral side portion 13 around the top portion 12, and a contact portion 14 that contacts a magnet key is provided at the center of the top portion 12. The top portion 12 is preferably substantially flat so that the magnet key can easily come into contact therewith, and the contact portion 14 has a circular shape or other desired shape.

  In the present invention, the outer case 8 is preferably formed of a nonmagnetic material. The reason why the outer case 8 is made of a non-magnetic material is that when the magnet is brought close to the outer case 8 in order to release the locking by applying a magnetic force to the stopper portion 9 locking the locking member 3. This is to prevent the magnetic force from acting. As this nonmagnetic material, for example, metals such as 18-8 stainless steel, brass, zinc, and aluminum can be preferably used from the viewpoint of strength and ease of manufacturing, and brass is particularly preferable. The outer case 8 can be manufactured from these materials by pressing.

  The inner case 7 is a part that forms the inner part of the female hook 1 (that is, the male hook side) together with the outer case 8 described above, and is preferably formed of a nonmagnetic material like the outer case 8. The inner case 7 has a substantially cylindrical portion 15 having a space for incorporating a locking member or the like therein, and a transparent hole 16 is provided at the bottom of the substantially cylindrical portion 15. The hook portion 4 of the male hook 2 can be taken in and out of the substantially cylindrical portion 15 through the transparent hole 16. Therefore, the diameter of the through hole 16 is preferably slightly larger than the maximum diameter of the hook portion 4 of the male hook 2.

  The retaining rod 5 is a component for attaching the outer case 8 and the inner case 7 to the base member 6 and can be obtained by, for example, cutting a brass plate into a predetermined shape and press-molding it. The center of the stopper rod 5 is opened to a predetermined size through which the hook portion 4 of the male hook 2 can be inserted, and a cylindrical stopper piece 18 is formed substantially upright at the periphery of the opening, The substantially cylindrical portion 15 of the inner case 7 can be fitted into the opening of the stopper piece 18.

  In order to attach the inner case 7 and the outer case 8 to the base material 6 with the retaining bar 5, a hole is made in advance in accordance with the size of the retaining piece 18 of the retaining bar 5 at a position where the female hook 1 of the base material is to be attached. The substantially cylindrical portion 15 of the inner case 7 is fitted into the hole through the stopper piece 18 of the stopper rod 5 from the back side of the base material into the hole, and the outer case 8 is overlapped with the stopper piece 18. And the edge of the inner case 7 and the outer case 8 are folded together and overlapped. In this case, if the tip of the stopper piece 18 of the stopper rod 5 is processed into a corrugated shape as shown in the drawing, the bending becomes easy. Further, in order to strengthen the attachment to the base material, a plurality of jagged portions 19 are provided around the stopper piece 18 of the stopper rod 5, and the head is processed into a sharp unevenness. Easy to bite. However, the method of attaching the female hook 1 to the base material may be a method implemented by a general-purpose hook or fastener, and is not limited.

Next, the locking member 3, the stopper portion 9, and the spring member 10 incorporated in the inner case 7 and the outer case 8 will be described. As the locking member 3 of this example, an elastic ring 22 (that is, a ring-shaped spring) is used. When the hook portion 4 of the male hook 2 is inserted into the locking member 3, the locking member 3 has a function of fitting into the engagement groove 20 of the hook portion 4 to stop the female hook and the male hook. Yes.
In a state where the elastic ring 22 is engaged with the engagement groove 20 of the hook portion 4 of the male hook 2, the elastic ring 22 is locked by the stopper portion 9 described below so that the elastic ring 22 does not spread outward. The stopper portion 9 is urged to prevent the lock from being released, and the hook portion 4 of the male hook 2 is prevented from being detached from the elastic ring 22.
Since the elastic ring 22 has moderate elasticity with a diameter that is substantially the same as or slightly shorter than the minimum diameter of the engaging groove 20 formed in the hook portion 4 of the male hook 2, the hook portion 4 is When proceeding in the inner direction of the stopper portion 9, the hook portion 4 proceeds while pushing and expanding the elastic ring 22, the outer periphery of the engaging groove 20 and the inner peripheral side of the elastic ring 22 are engaged, and the hook portion 4 further stops the stopper. When it advances to the inner part of the part 9, the outer peripheral side of the elastic ring 22 is accommodated in the receiving part 23 of the stopper part 9, and both are engaged, so that the female hook 1 and the male hook 2 are connected, and a locked state is obtained.

  If the inner side of the abutting portion 14 of the outer case 8 is structured so that the stopper portion 9 can be fixed, the elastic ring 22 is pushed up to a certain level by the hook portion 4 when the hook portion 4 is inserted toward the stopper portion. This can also be prevented by the stopper portion 9. If the stopper portion 9 is not configured as described above, the elastic ring 22 is pushed up by the hook portion 4 when the hook portion 4 is pushed into the elastic ring 10. It becomes difficult to expand and engage with the engaging groove 20.

  Further, when the elastic ring 22 and the hook portion 4 are detached and the locked state between the female hook 1 and the male hook 2 is released, the magnet key is applied to the abutting portion 14 of the magnetic key of the stopper portion 9. As described below, the locked state of the female hook 1 and the male hook 2 can be released by the magnetic force of the magnet key.

  When the female hook 1 and the male hook 2 are stopped, the spring member 10 restrains the operation of the stopper portion 9 with an elastic force to be biased, and unless the magnetic force larger than the elastic force acts on the stopper portion 9. The stopper portion 9 has a role of holding the locking of the locking member 3. When a magnetic force larger than the elastic force is applied to the stopper portion 9 from the outside of the outer case 8, the stopper portion 9 is moved to the outer case side against the elastic force to release the locking to the locking member 3. Let For this reason, it is important that the elastic force of the spring member 10 is smaller than the magnetic force acting on the stopper portion 9, and the magnet used has a strong elastic force that allows the release of the locking to be smoothly and reliably obtained. Selected by the strength of. Although the coil spring is used in this example, the spring member 10 is not limited to this as long as it can urge a predetermined elastic force to the stopper portion 9. For example, a leaf spring, a bamboo spring, a spiral spring, a wire spring, a wire spring, a rubber elastic body, or the like can be used, and the spring member of the present invention includes these. Furthermore, the position and method of the installation can be determined as appropriate.

  Next, the case where the female hook 1 of this example is assembled using various components will be described. A stopper piece 18 of the stopper rod 5 is inserted from the back side into a hole formed in the base material at a position where the female hook 1 is attached, and then the substantially cylindrical shape of the inner case 7 is inserted into the opening inside the stopper piece 18 of the stopper rod 5. After the portion 15 is inserted and stacked, the locking member 3 is placed inside the inner case 7. And the spring member 7 is mounted on the outer peripheral part of the outer periphery of the stopper part 9, and the outer case 8 is overlapped from above. Thus, after the locking member 3, the stopper portion 9 and the spring member 7 are assembled between the inner case 7 and the outer case 8, The female hook 1 can be obtained by bending the stopper piece 18 in a state where the stopper pieces 18, the inner case 7 and the outer case 8 are overlapped.

Next, the male hook 2 will be described with reference to FIG. The basic configuration of the male hook 2 of the present example is the same as that of a general-purpose normal hook, and includes a stop pin portion 11 and a hook portion 4 as shown in FIG. For example, a metal such as brass or stainless steel is preferably used as the material. The retaining pin portion 11 has a cylindrical portion 28 planted at the center of the pedestal 27, and the hook portion 4 has a retaining projection 30 planted on the pedestal 29. A cylindrical hole 31 for inserting the cylindrical portion 28 is provided through the pedestal 29, and an engaging groove 20 for engaging the locking member 3 of the female hook 1 is provided outside the locking projection 30. It is formed all around.
On the other hand, it is preferable that a stepped portion is provided inside the cylindrical hole 31 as shown in FIG. 1, and the cylindrical portion 28 of the stop pin portion 11 is inserted into the mounting hole provided in the base material 6, The retaining pin portion 11 and the hook portion 4 can be fixed by inserting the cylindrical hole 31 of the hook portion 4 into the cylindrical portion 28 from the front side of the base material and expanding the tip portion outward. Thereby, the male hook 2 can be attached to the base material 6.

In the present invention, the female hook can be locked and unlocked from the surface side of the female hook, that is, from the surface side of the top portion 12 of the outer case 8.
FIG. 6 is an example showing an outline of the configuration, (a) is a schematic explanatory view showing a released state of the female hook, and (b) is a schematic explanatory view showing a locked state of the female hook. . The substantially frustoconical stopper portion 9 is accommodated in the inner case 7 of the female hook so as to be rotatable about the central axis of the hook portion of the male hook. On the peripheral edge of the circumferential portion, there are provided locking recesses 34 at one place, two places every 180 degrees, or four places every 90 degrees. On the other hand, the engaging recess 34 is engaged with a peripheral edge portion of the inner case 7 corresponding to the peripheral edge portion of the stopper portion 9 so that the rotation of the stopper portion 9 is restricted and locked. The unit 35 is provided at one place, two places every 180 degrees, or four places every 90 degrees. The stopper 9 is rotated, and the lock is released when the engagement recess 34 of the stopper and the engagement projection 35 of the inner case are disengaged.

The example shown in FIG. 6 is an example in which a locking concave portion 34 is formed at a predetermined position of the stopper portion 9 and a locking convex portion 35 for restricting the rotation angle of the stopper portion is formed at a predetermined position of the inner case. However, a locking projection is formed at a predetermined location of the stopper portion 9, while a locking recess for regulating the rotation angle of the stopper portion is formed at a predetermined location of the inner case, and the locking projection of the stopper portion is formed When the engaging recess of the inner case is engaged, the female hook and the male hook are locked, and the engaging protrusion of the stopper portion is disengaged from the engaging recess of the inner case. It is good also as a structure where a lock is sometimes released.
In addition, the top plate portion 24 of the stopper portion 9 is provided with a rotation operation portion 36 so that the rotation operation of the stopper portion 9 can be performed by contact or fitting of the magnet key 33 or by the movement of a human finger. ing. The rotation operation unit 36 may be provided with a display of a rotation direction to be locked and a rotation direction to be unlocked so that the operation can be easily performed as necessary. With such a configuration, the operation of locking and unlocking the female hook can be facilitated by the rotation of the stopper portion 9.

  As an example in which the rotation of the stopper portion 9 described above can be performed using the magnet key 33, the tip of the magnet key 33 is fitted to the rotation operation portion 36 provided on the top plate portion 24 of the stopper portion. The form which provides the convex part 37 which matches is mentioned. For example, a convex portion of a predetermined design pattern such as a character or a pattern (that is, a convex portion having a male key pattern) is provided on the surface of the tip portion of the magnet key 33 fitted to the rotation operation portion 36, and this design pattern A concave portion (that is, a concave portion having a female reversal key pattern) is provided in the rotation operation portion 36, and the convex portion of the magnet key 33 and the concave portion of the rotation operation portion 36 are fitted, The magnet key 33 can be rotated so that the female hook can be locked and unlocked. Or it is good also as a structure where it is easy to lock and cancel | release the shape of a rotation operation part easily by operation of a person's finger | toe.

  In this example, a configuration has been described in which the convex portion of the design pattern is provided on the surface of the tip portion of the magnet key 33 and the convex portion and the concave portion of the rotation operation portion 36 are fitted. It is good also as a form which provides the recessed part of a design pattern in the surface, provides a convex part in the said rotation operation part 36, and fits both. Thus, if a predetermined character, a convex portion of a design, and a concave portion are provided at the tip of the magnet key 33, the design can be improved by appropriately designing the design pattern of the character and the design. Fashion can also be improved. FIG. 7A illustrates an example of the design of the tip of the magnet key. In FIG. 7, an example in which a convex portion 37 corresponding to the English letter T is provided is shown in FIG. These are the partial top views of the rotation operation part 36 of the top-plate part 24 of the stopper part 9 in which the convex part 37 of the said magnet key 33 fits, and the recessed part 38 was provided.

FIG. 8 shows a state from before the female hook 1 and the male hook 2 are stopped to when the female hook 1 and the male hook 2 are removed. In the figure, main reference numerals are omitted.
(A) is a state immediately before the female hook 1 and the male hook 2 are stopped.
(B) is a state in which the hook portion 4 of the male hook 2 is pushed into the locking member 3 of the female hook 1, and when the hook portion 4 is pushed into the locking member 3, the hook portion 4 pulls the locking member 3 (elastic ring). The engaging member 3 is engaged with the engaging groove 20 of the hook portion 4 at the end of the pushing operation.
(C) is a state in which the locking member 3 is locked by the stopper portion 9. Since the spring member 10 is urged from below on the stopper portion 9 that has locked the locking member 3 in this state, the locking of the locking member 3 by the stopper portion 9 is held without being released. . Therefore, in this state, even if the female hook 1 and the male hook 2 are to be removed, the locking member 3 is prevented from spreading outward by the stopper portion 9, so that the engagement of the hook portion of the male hook 2 is prevented. It is impossible to disengage from the engaging groove 20. As a result, the female hook 1 and the male hook 2 cannot be removed.

(D) has shown the removal process of this female hook 1 and the male hook 2. FIG. This is possible by bringing the magnet key 33 closer to the outside of the female hook 1 as shown in FIG. That is, when the magnet key 33 is brought closer to the outside of the rotation operation portion of the stopper portion 9 of the female hook 1, the stopper portion 9 made of a magnetic material is attracted to the magnet key 33 side by the magnetic force of the magnet key 33, and the elasticity of the spring member 7. Since it moves against the force, the stopper portion 9 that has been locking the locking member 3 is released from the locking member 3 and releases the locking. By releasing the locking, the locking member 3 can be expanded outward. Therefore, when the female hook 1 and the male hook 2 are separated, the hook portion 4 of the male hook 2 pushes the locking member 3. Since it separates while spreading, both can be removed.
When the locking member 3 is an elastic ring 22, when the locked female hook 1 and male hook 2 are removed, the magnetic force of the magnet key 33 is applied to the stopper portion 9 from the outside of the female hook 1 so that the stopper portion 9 is moved. The elastic member 22 is moved against the elastic force of the spring member 10 to release the engagement with the elastic ring 22, and the elastic ring 22 can be pushed and removed by the hook portion 4.

  In the present invention, the magnet key 33 used for removing the female hook 1 and the male hook 2 may be a permanent magnet or an electromagnet as long as a magnetic force with a predetermined strength can be obtained. However, the permanent magnet is superior in that the magnet itself has a simple structure and does not require a power source, so that it is suitable for weight reduction and miniaturization and can be easily carried. The magnet key 33 in the present invention can be used as long as it has a magnetic force of a predetermined strength that can be unlocked by a magnetic force, and is appropriately selected depending on the shape, size, application, and usage form of the fastener.

  FIG. 9 shows an example of a portable magnet key 39 using a permanent magnet. The magnet key 39 of the present example is provided with a magnet 41 ( In addition, a string hole 43 is provided at the end of the grip portion 42 of the holder 40, and a string 44 is attached to the string hole for easy carrying. However, in the present invention, the magnet key 39 is not limited to this, and is appropriately selected depending on the shape, size, application, and usage of the fastener.

(A) of FIG. 10 is an example in which the fastener 50 with a lock mechanism of the present invention is applied as a fastener with a simple lock of the bag product 51, and the lock function of the female hook is provided when necessary. If it is in a working state, the lid of the bag product 51 cannot be opened unless it is unlocked with a magnet key. On the other hand, if the lock function of the female hook is released, the cover of the bag product 51 can be opened without a magnet key. (B) of FIG. 10 is an example in which the fastener 60 with a lock mechanism of the present invention is used as a fastener at the end portion of the opening / closing slider 62 of the nursing sleepwear 61 as an example of a clothing product. If the lock function of the female hook is activated, the opening / closing slider 62 of the nursing sleepwear 61 cannot be opened unless the lock is made with the magnet key.
