Abstract

The present invention provides a magnetic lock that enhances the strength of the assembly and prevents the difference between the first assembly and the second assembly.

The first assembly has a locking means, while the second assembly has a guide means. The first assembly and the second retaining means when the assembly is to be combined can be directed into the interior of the guide means. The combination of the assemblies can be automatically locked by using the magnetism of the magnet in the retaining material installed in the second assembly. Moreover, the edge-shaped guide means which covers the side surface of the adsorption surface of the other assembly from the outer side is provided in the side surface of the adsorption surface of one assembly. Moreover, the expansion guide part is provided in the locking means of a 1st assembly, and the side difference of those assemblies can be prevented by combining this extension guide part and the hole of a 2nd assembly. In addition, by providing a magnetic gap member between the locking material and the magnet, the locking material can be moved smoothly.

Description

Magnetic lock

The present invention relates to a magnetic lock, and more particularly, to a simple magnetic lock that can automatically lock the closed state by using the properties of the magnet.

Various locking mechanisms are designed to keep the lids of each case closed, such as, for example, a handbag or a bag, a randcell, a look, a belt, a cigarette, an attachment case . Magnetic locks using magnetic force are one of them.

One example of such a magnetic fastener is disclosed in Japanese Patent Publication No. 2944643 (Japanese Patent Application Laid-Open No. 10-194638) filed by the present applicant. The magnetic locking mechanism is composed of a first assembly and a second assembly, and is fixed to, for example, a lid and a main body of a handbag. These assemblies allow the lid and the main body to be closed when they are combined with each other by the action of the magnetic, and to automatically lock the closed state.

In more detail, these assemblies utilize magnetic action while adsorbing and combining each other at the front of the assembly while allowing protrusions provided on the front surface of the first assembly to pass through the holes provided on the front surface of the second assembly. In this case, when the first assembly and the second assembly are to be detached by adsorbing the locking member provided in the second assembly in the middle of the protrusion of the first assembly, the protrusions provided at the tip of the protrusion of the first assembly are adsorbed in the middle of the protrusion. It is to be able to lock the combination by colliding with the locking member of the two assemblies.

Generally, metal is considered to be suitable as a material for granules. However, in order to suppress manufacturing costs, it is preferable to process these metals by punching, drawing or bending, for example, inexpensive thin metal plates. However, when using a thin metal plate, the strength is a big problem. As a particularly problematic case, for example, fixing of the assembly can be given. As described above, the assembly is used by being fixed to a handbag or the like, but this fixing operation also includes bending a part of the metal plate by tapping with a hammer or the like. If the strength of the assembly is weak, the assembly is easily broken or deformed by this operation. Therefore, the strengthening of the strength of the assembly is strongly desired. It is of course also possible to form the assembly from a member other than a metal, for example plastic.

In addition, as described above, when the first assembly and the second assembly are combined, the protrusion of the first assembly is passed through the hole of the second assembly, but when the first assembly and the second assembly are combined, or thereafter, Differences can arise in the direction of interlocking direction (hereinafter referred to as the up and down direction) (the transverse direction). This difference will hinder the good movement of the magnetic lock. For example, if the protrusion provided at the tip of the protrusion of the first assembly has a difference in the cross direction from the hole of the second assembly, the protrusion will collide with a part of the second assembly unless the difference is corrected. It is difficult or impossible to remove them.

In the magnetic locking device disclosed in the above-mentioned patent publication No. 2944643 by the applicant of the present application, in order to prevent such a difference, it protrudes from the front surface of the second assembly to the front surface. The annular projection is provided so that the front surface of the first assembly is accommodated in the annular projection when the first assembly and the second assembly are combined or thereafter. However, the provision of such annular projections makes the annular projections thick, which is inconvenient when opening the lid, which is undesirable in design, and has the drawback of making the device appear thick. It is indispensable to provide a means for preventing the difference, but it is therefore undesirable to damage the appearance.

The present invention was made to further improve the magnetic locking device developed by the applicant of the present application, and enhances the strength of the assembly and prevents the difference between the first assembly and the second assembly without damaging the appearance. The purpose is to provide.

Example

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

1 shows an assembled perspective view of the magnetic lock according to the present invention. As shown in this figure, the magnetic locking device according to the present invention is composed of a combination of a first assembly 1 and a second assembly 2. Each of these assemblies is shown in one direction of one set of corresponding members (for example, the main body and lid of the handbag) of the object (for example, handbag) to which the magnetic lock is to be used, as described later. Is fixed. These assemblies are formed by the respective adsorption surfaces 31 and 67 (see FIG. 3 described later) in the direction in which the first assembly and the second assembly are combined with each other (arrows in Fig. 1) by the action of a magnet installed in the first assembly. Shown in Fig. 2), they are adsorbed and combined with each other, and the corresponding member of the object can be kept closed. The magnetic lock is automatically locked at the same time the combination of the first assembly and the second assembly is performed by the action of the magnet. This lock can be released simply by manipulating the second assembly.

Fig. 2 shows an exploded perspective view of each of these assemblies, and Fig. 3 shows a centerline cross-sectional view of the magnetic lock of the present invention when these assemblies are combined. These figures make the details of the components constituting each assembly clear. Hereinafter, the detail of each component is mainly demonstrated with reference to FIG.

First, the first assembly will be described.

As shown on the left side of Fig. 2, the first assembly includes an annular plate 10, a fixing piece 14 fixed to the annular plate 10, and a ring-shaped magnet attached to the annular plate 10. 22, a cylindrical sleeve 26, a cover 30 covering the magnet 22 and the annular plate 10, and a locking pin 34 provided through the center of the first assembly. However, as will be described later, the annular plate 10 can be omitted.

The annular plate 10 is made of iron of magnetic material, for example ferromagnetic material. Thus, the annular plate is affected by the magnet. The same applies to the components described below, but in the case where iron is used as the material such as an annular plate, plating is generally performed for rust prevention and decoration. The hole 12 provided in the center of the annular plate 10 is a hole for penetrating the retaining pin 34 later.

The fixing piece 14 is fixed to one surface of the annular plate 10. As the fixing method, for example, spot welding, soldering, welding such as brazing, caulking, or other suitable method can be used. In this embodiment, spot welding and caulking are employed to more securely fix the fixing piece 14. The four dot portions 15 indicated by the dotted lines in the figure show the molten portions formed by the spot welding. The positions of these molten portions are spaced at equal intervals on almost the same circumference so that force is applied evenly to the stationary piece. And like a present Example, these can be molded into one piece, without making the fixed piece 14 and the annular plate 10 separate. The material of the stationary piece is not particularly in question, but if the stationary piece is molded with the annular plate, it becomes the same material as the annular plate. In addition, the fixing piece 14 may have an effect as the annular plate 10. When the magnets 22 are made of plastic magnets, either one of the annular plate 10 or the fixed piece 14, or both of them may be molded in one body with the plastic magnets, or in one body with other members. . In addition, various members may be attached to other members by screws, caulking, welding, or other methods. The plastic magnet may also be plated.

A fixing piece (14) is made of a annular section 16, a fixing portion 18 of the second stretching downward from both sides of the annular portion (16) coming from. The annular portion 16 is used to fix the annular plate 10, and the fixing portion 18 is used to fix the first assembly to the object. In the center of the annular portion 1 6 , a hole 20 having a size substantially the same as that of the annular plate 10 is formed. When the fixing piece 14 and the annular plate 10 are aligned with each other, the hole 20 of the annular portion 16 and the hole 12 of the annular plate 10 are aligned with each other, whereby the locking pin 34 An alignment hole for penetrating the hole is formed.

The ring-shaped magnet 22 is mounted on the surface of the annular plate 10 on the side opposite to the mounting side of the fixing piece 14. The outer diameter of the magnet 22 is preferably smaller than the outer diameter of the annular plate 10 for the reason described later. This magnet 22 is a permanent magnet having one pole of either the N pole or the S pole on the front and back surfaces. Thus, the magnet 22 can be attached to the annular plate 10 by its magnetic force. When the magnet 22 is magnetized to the annular plate 10, the annular plate is magnetized by the magnet, so that the annular plate itself also generates magnetic force. This magnetic force of the annular plate plays an important role, in particular, for adsorbing the cylindrical sleeve 26. The magnet 22 may be a neodymium magnet or another magnet. The thickness of the magnet is preferably 0.5 mm to 10 mm, but the design of the thickness is free and the magnets may be plated.

The cylindrical sleeve 26 is mounted on the surface of the annular plate 10 on the same side as the magnet 22. In this embodiment, the cylindrical sleeve 26 may be placed away from the center of the annular plate 10, annular plate 10, but disposed near the center, a cylindrical sleeve (26) of. When the cylindrical sleeve 26 is disposed near the central portion of the annular plate 10, the cylindrical sleeve 26 is spaced directly from the hollow portion 24 of the magnet 22 and directly on the annular plate 10. Is placed. However, the cylindrical sleeve 26 does not necessarily need to be separated from the magnet 22 and may be in contact with the magnet 22. In other words, the cylindrical sleeve 26 may be directly placed therein without being provided with the annular plate 10 in contact with the ring hole of the magnet 22. In that case, the annular plate 10 can also be omitted. When the magnets 22 are made of plastic magnets, the magnets 22 may be integrally formed with the cylindrical sleeves 26. The annular plate 10 or the fixed piece 14 may be attached to the cylindrical sleeve 26 by screws, welding, or other methods, and both of them may be mounted.

The cylindrical sleeve 26 is formed of a magnetic body similarly to the annular plate 10. Thus, the cylindrical sleeve 26 can be attached to the magnetized annular plate 10. Obviously, when the cylindrical sleeve 26 is fixed to the annular plate 10, the cylindrical sleeve 26 floats magnetism like the annular plate 10, so that the cylindrical sleeve 26 itself also generates magnetic force. . This magnetic force of the cylindrical sleeve 26 plays an important role in adsorbing the locking material 56 described later. The cylindrical sleeve 26 and the annular plate 10 may be integrally molded.

When the cylindrical sleeve 26 is fixed to the annular plate 10, the vicinity of the tip of the cylindrical sleeve 26 may protrude above the magnet 22. In other words, the cylindrical sleeve 26 protrudes outward from the adsorption surface 31 of the first assembly toward the combination direction with the second assembly (arrow direction in Fig. 1). The cylindrical sleeve 26 is also provided with a hole 28 for penetrating substantially the same size as the hole 20 of the fixing piece 14 and the hole 12 of the annular plate 10 along the longitudinal direction thereof. . When the cylindrical sleeve 26, the annular plate 10, and the fixing piece 14 are all aligned, their respective holes form an alignment hole for penetrating the retaining pin 34. As shown in FIG.

The cover 30 is attached to the magnet 22 and the annular plate 10. The shape of the cover 30 is ring-shaped. In addition, the size is very good to cover almost the front of the magnet 22 and the side of the annular plate 10. As described above, when the outer diameter of the magnet 22 is set smaller than the outer diameter of the annular plate 10 as in the present embodiment, the edges of the cover do not need to be raised, and thus a beautiful and smooth curved surface at the edge thereof. Can be formed. When the cover 30 is covered with the magnet 22 and the annular plate 10, five fixing parts 32 extending downwardly formed over the bottom circumference of the cover 30 are formed of the annular plate 10. It can protrude downward from the bottom. By bending these fixing parts 32 inward along the bottom surface of the annular plate 10, the cover 30 can be fixed to them in a state in which the magnet 22 and the annular plate 10 are integrated. The material of the cover is not particularly limited, but is made of nonmagnetic material such as brass. Such a cover 30 is provided to protect the magnet 22 and the annular plate 10 and to further strengthen the coupling therebetween, but this may be omitted. In addition, The outer diameter of the magnet 22 may be smaller or larger than the outer diameter of the annular plate 10. Moreover, the shape of the magnet 22 is also not asked. However, when the cover 30 is not provided, it is preferable to fix them by an adhesive or other method in order to further strengthen the coupling between the magnet 22 and the annular plate 10. When the cover 30 is provided, the adsorption surface with the adsorption surface 67 (refer FIG. 1, FIG. 3) of the 2nd assembly becomes the front side 31 of the base cover 30. As shown in FIG. On the other hand, when the cover 30 is not provided, the suction surface with the second assembly becomes the front side 21 of the magnet 22 positioned below the cover 30. In addition, even when the cover 30 is provided, the cylindrical sleeve 26 protrudes outward from the adsorption surface 31 of the first assembly toward the combination direction with the second assembly (the arrow in FIG. 1 is directed). .

The retaining pins 34 are installed in the state of being inserted into the alignment holes formed by the respective holes of the cylindrical sleeve 26 or the annular plate 10 and the fixing piece 14. The locking pin 34 is composed of a strut 36 and a head 38 provided on an upper portion of the strut 36. Only the portion of the strut 36 of the locking pin 34 passes through the alignment hole, and the portion of the head 38 does not.

The length of the strut 36 of the locking pin 34 is longer than the total length of the alignment holes formed by the holes of the cylindrical sleeve 26 or the like. Therefore, when the strut 36 of the locking pin 34 is penetrated through the alignment hole, the vicinity of the tip of the strut 36 can protrude from the hole 20 of the fixing piece 14 which forms the lowest side of the alignment hole. have. The protrusions (not shown) of this support (36) are welded to the bottom of the fixing piece (14), or the protrusions of the support (36) are welded, screwed, or other suitable method to the fixing piece (14). By fixing, the locking pin 34 can also be fixed to the annular plate 10 or the cylindrical sleeve 26. In addition, when the locking pin 34 is fixed thereto, the vicinity of the distal end of the strut 36 of the locking pin 34 may be flat with respect to the bottom surface of the fixing piece 14.

When the locking pin 34 penetrates the alignment hole, the head 38 of the locking pin 34 is exposed to the outside from the upper portion of the cylindrical sleeve 26. At least part of this head 38 is formed of nonmagnetic material and, thus, is not affected by magnets. As will be described later, when the first assembly and the second assembly are combined, the head 38 penetrates through the center portion of the second assembly. However, as described above, the head is not affected by the magnet, so that the head is the second assembly. Self-locking on any part of the assembly does not interfere with the combined operation of the first assembly and the second assembly. The portions other than the head, that is, the support 36 may be made of magnetic material or nonmagnetic material. Forming an inclined surface on the head 38 of the locking pin 34 reduces the frictional resistance generated between them even when the head 38 contacts the locking portion 65 of the slider 56 so that the locking portion 65 is reduced. It is to facilitate the insertion of the head 38 into the alignment holes of the second assembly by smoothly moving it.

Next, the second assembly will be described.

As shown in the right side of Fig. 2, the second assembly includes an annular frame 66, a reinforcing plate 80 accommodated in the annular frame 66, and an accommodating member defining an accommodating space therebetween. 40) it consists of a reinforcing plate 80 and the receiving member 40 is flexible slider (56 is held in) in the accommodation space formed by the, and the receiving member (a fixing piece 48 is fixed to 40) coming from.

The annular frame 66 is preferably formed of a ferromagnetic material (magnetic material) such as iron. By forming the magnetic material, the following excellent effects can be obtained. First of all, the magnetic force from the first assembly can reach the annular frame 66 when the first assembly and the second assembly are combined. In other words, the magnetic force to the slider 56 of the first assembly is to be happily Mitch even as well as annular frame 66, it is possible to generate a stronger attraction force between the first assembly and the second assembly. Secondly, when the first assembly and the second assembly are combined, the annular frame 66 can function as a yoke to smoothly operate the slider 56. And even when the annular frame 66 is formed from plastic, brass, and other nonmagnetic materials, the latter effect may be acquired in some cases. This will be described later.

The annular frame 66 is integrally formed by punching, bending and drawing a relatively thin and smooth metal plate. By using such a manufacturing method, manufacturing cost can be made cheap. However, it is not necessary to necessarily do it at all, and other manufacturing methods may be sufficient. For example, the cylindrical guide 69 may be provided separately from the annular frame 66 and other portions, and may be attached later. Instead of providing the guide 69 in the annular frame 66, a member corresponding to the guide 69 may be formed on the side of the housing member 40. In addition, a part of the guide 69 (or a member corresponding to the guide) may be provided on both the annular frame 66 and the accommodation member 40 to form a complete guide. Of course, the material and manufacturing method of the annular frame 66 are the freedom of the designer.

The annular frame 66 is formed as a frame (frame) surrounded by three sides of the outer wall portion 68, the inner wall portion, that is, the guide 69, and the front wall portion 70. Although not apparent from the drawing, the annular projection as described in the prior art is not formed on the front surface (adsorption surface) of the annular frame 66, that is, the front wall portion 70, and is in a flat state. This front surface (surface opposite to the surface shown in the drawing) is used as the adsorption surface 67 which is adsorbed with the adsorption surface 31 of the first assembly.

Note that the inner wall portion, i.e., the guide 69 is provided, has a substantially cylindrical shape with a substantially constant inner diameter, and the suction surface 67 (see Figs. 1 and 3). From the direction of the combination with the first assembly (arrow or direction in Fig. 1) from the direction is directed to the hole inside the second assembly. There are mainly three meanings for installing the guide 69. The first is to prevent the transverse difference between the first assembly and the second assembly. It is not necessary to deliberately install such a guide 69 when the first assembly and the second assembly are combined or after they are combined to generate no transverse difference or only a slight difference. In practice, however, relatively large differences usually occur, and such differences hinder the good functioning of the magnetic lock.

The primary meaning of installing the guide 69 is to solve this problem. That is, when the first assembly and the second assembly are combined or after they are combined, they prevent the transverse difference between the first assembly and the second assembly from occurring. More specifically, with reference to FIG. 3, by installing the guide 69 in the second assembly, the head 38 of the locking pin of the first assembly is formed along the hole 71 formed inside the guide 69. To be guided into the interior of the assembly, or to prevent the head from laterally exiting the interior of the second assembly after they are guided, for example, when attempting to release the lock by pressing the slider 56 This force prevents the annular frame 66 from being pushed in the lateral direction and the hole 71 from escaping from the head 38.

The second meaning of providing the guide 69 is to enhance the strength of the annular frame 66 in the vertical direction. As will be described later, the second assembly is to bend and fix the fixing portions 54 of the fixing piece 48 fixed to the receiving member 40 to an object such as a handbag by beating and hammering, respectively, In the vicinity of the fixing piece 48, that is, the center of the receiving member 40 and the annular frame 66, a considerable force is applied in the vertical direction. This force is large enough to destroy or deform the receiving member 40 and the annular frame 66 (thus the second assembly itself). Furthermore, in the case where the annular frame 66 is formed from a thin plate of relatively low strength as in the present embodiment, the annular frame 66 (the second assembly itself) is easily broken or deformed during this operation to accommodate the slider ( 56 cannot flow. Therefore, in the present invention, the guide 69 is provided near the central portion of the annular frame 66, and this problem is solved by reinforcing the annular frame with the reinforcing guide 82 of the reinforcing plate 80 and enhancing its strength. .

The third meaning of installing the guide 69 relates to the cutout 72 provided in one part of the guide 69. This cutout 72 is a magnetic sleeve of the first assembly in which the slider 56, in particular its locking portion 65, is placed inside the guide 69, that is, inside the guide 69. To adsorb). This cutout portion is necessary and sufficient in size to pass through the locking portion 65. Conversely, the guide 69 is formed in the continuous state with respect to parts other than the notch 72. The third meaning in which the guide 69 is provided is to prevent the slider 56 from being magnetized at portions other than the cutout portion 72. In other words, the guide 69 is the locking portion 65 of the slider 56. It serves to function as a magnetic shield for other parts.

The guide 69 is formed over an angle range larger than at least 180 degrees, for example, an angle range of about 240 degrees in this embodiment so as to achieve these three meanings sufficiently. This angular range is sufficient to adsorb the slider 56 to the first assembly by magnetic action exerted on the locking portion 65 of the slider 56, and when the first assembly and the second assembly are combined, or After they are combined, it is sufficient to prevent the transverse difference from occurring between them and to strengthen the up and down strength of the annular frame 66. If this is set to an angle range of 180 degrees or less, for example, the head 38 of the locking pin 34 protrudes from the guide 69 and cannot have significance as the guide 69, and only insufficient strength can be obtained. do. Of course, nevertheless, it is the freedom of the designer to have an angular range of 180 degrees or less. The length of the guide 69 is substantially equal to the length formed by the cylindrical sleeve 26 and the head 38 in the combination direction of the first assembly and the second assembly. The inner diameter is slightly larger than the outer diameter of the head 38. The length and the inner diameter of the guide 69 are free.

The reinforcement plate 80 serves to reinforce the annular frame 66. Conversely, since the reinforcing plate 80 is provided only to reinforce the annular frame 66, it may be omitted. The reinforcement plate 80 is received therein from the opened rear portion of the annular frame 66 in the direction shown.

The reinforcing plate 80 is formed in one piece by punching, drawing, bending, etc. similarly to the annular frame 66, but it is not necessary to form one piece, and the same shape may be formed by another manufacturing method. . The sheet metal to be used may be the same as the annular frame 66, and can be formed in substantially the same process as the annular frame 66. In this case, manufacturing costs are very inexpensive. However, like the annular frame 66, it is not necessary to necessarily form one piece, and this may be formed of a nonmagnetic material.

The reinforcement plate 80 has a shape and size for enhancing the strength of the annular frame 66, in particular the front wall portion 70 and the inner wall portion, ie the guide 69. That is, the reinforcement plate 80 corresponds to the front wall portion 70 of the annular frame 66 and has a substantially donut-shaped body portion 81 and a body 69 corresponding to the guide 69 of the annular frame 66. It has the reinforcement guide part 82 extended in an up-down direction.

When the reinforcement plate 80 is accommodated in the annular frame 66, the body portion 81 of the reinforcement plate 80 is almost entirely inside the front wall portion 70 of the annular frame 66, that is, of the annular frame 66. Cover the surface on the opposite side to the adsorption surface. The protruding portion 83 formed on the outer circumference of the main body portion 81 is a cutout 73 formed correspondingly to the outer wall portion 68 of the annular frame 66 when the reinforcing plate 80 is accommodated in the annular frame 66. ) The reinforcement plate 80 is accommodated in the annular frame 66 in a predetermined direction by the fitting of these protrusions 83 and the cutout 73, and after the reinforcement plate 80 is accommodated in the annular frame 66. The reinforcement plate 80 can be kept in the predetermined direction with respect to the annular frame 66.

The reinforcement guide 82 is formed over an angle range smaller than the guide 69 of the annular frame 66, for example, 180 degrees, but may be the same angle as the guide 69. In addition, the height of the reinforcement guide 82 is set to be lower than or equal to the height of the guide 69 of the annular frame 66 when the reinforcing plate 80 is accommodated in the annular frame 66. However, when it is set to be low, the step | step 84 (refer FIG. 3) is formed in relationship with the guide 69. FIG. This will be described later. As is apparent from the relationship between the angular range of the reinforcing guide 82 and the angular range of the guide 69 of the annular frame 66, the reinforcing guide 82 does not encompass the perimeter of the guide 69 of the annular frame 66. The role of reinforcing the annular frame 66 is sufficient. In addition, although it may be over the circumference | surroundings of the guide 69 of the annular frame 66, and also larger angular range, in this case, the notch for the locking part 65 of the slider 56 must be secured. On the other hand, as evident from the relationship between the height of the reinforcing guide 82 and the height of the guide 69 of the annular frame 66, when the reinforcing plate 80 is accommodated in the annular frame 66, their guides 69 and 82. As a result, a step 84 in the vertical direction as shown in FIG. 3 is formed. This step 84 formed by the two guides is complementary to the step 47 formed in the receiving member 40. As will be described later, by arranging these steps 84 and 47 correspondingly, the holes formed by the guide 69 can be substantially extended while the alignment holes are formed with substantially no gap, thereby increasing the strength thereof. It may be.

By using the reinforcing plate 80 as a ferromagnetic material (magnetic material) such as iron, various effects described in connection with the annular frame 66 can be obtained. If the reinforcing plate 80 is provided only to increase the strength of the annular frame 66, the purpose is sufficiently achieved even if it is made of nonmagnetic material. However, the reinforcing plate 80 may be formed of a magnetic material as long as it is desired to reinforce the suction function of the annular frame 66 or the function of the yoke by the reinforcing plate 80, that is, the reinforcing plate 80 may be formed of a magnetic material. By forming, the magnetic force of the first assembly at the time of the combination of the first assembly and the second assembly extends not only to the slider 56 and the annular frame 66 but also to the reinforcing plate 80, so that the first assembly and the second assembly are more than the space between the first assembly and the second assembly. A strong adsorption force can be generated, and in addition to the annular frame 66, the reinforcing plate 80 can also function as a yoke for magnetism from the first assembly, thereby making the slider 56 smoother. These effects can be obtained even when the reinforcing plate 80 and the annular frame 66 are formed of a nonmagnetic material, as described later. However, both the reinforcing plate 80 and the annular frame 66 are magnetic materials. In the case of forming a larger effect can be obtained.

The slider 56 is used to automatically lock between them when the first assembly and the second assembly are combined. In other words, when the first assembly and the second assembly are combined, they are attracted to and adsorbed to the first assembly by magnetic action from the first assembly, in particular its cylindrical sleeve 26. This adsorption action is the lock action between the first assembly and the second assembly.

In the present embodiment, the slider 56 is molded into one piece by punching, bending, drawing, etc. in order to reduce the manufacturing cost. However, the slider 56 is not necessarily formed by one piece and may be other manufacturing methods. This point is the same as the annular frame 66 and the reinforcement guide 82. Finally, the slider 56 has a substantially key shape (may be another shape) that is almost symmetrical. The hole 64 formed near the center thereof penetrates the engagement pin 34 of the first assembly and the cylindrical sleeve 26 provided around the engagement pin 34 when the first assembly and the second assembly are combined. Will be located.

The slider 56 is provided with a main body portion 61 and a lever portion 60. The main body portion 61 is provided with a locking portion 65 which protrudes inward again. The locking portion 65 is adsorbed to the cylindrical sleeve 26 disposed around the locking pin 34 of the first assembly when the first assembly and the second assembly are combined, and are important for automatically locking their assemblies. It works. The locking portion 65 has a substantially crescent shape (other shape may be the whole) as a whole, and at the end thereof, a thin inclined surface having a thin front face corresponds to thinning of the head 38 of the locking pin 34 of the first assembly. Although formed, it is not necessary to, of course. By matching the shape of the locking portion 65 and the shape of the locking pin 34, even when the locking portion 65 and the head 38 of the locking pin 34 are in contact when the first assembly and the second assembly are combined, The frictional resistance between them can be reduced. And the adsorption | suction to the cylindrical sleeve 26 is made in the vicinity of the front-end | tip of the inclined surface of the locking part 65. As shown in FIG. On the other hand, the lever portion 60 is used to release the lock by detaching the locking portion 65 adsorbed to the cylindrical sleeve 26 from the first assembly.

The slider 56 is disposed on the reinforcing plate 80 housed in the annular frame 66, the main body portion 61 of which is covered by the receiving member 40 from above. As shown in Fig. 3, the housing member 40 is provided with a space 49 for accommodating the slider 56, and the main body portion 61 of the slider 56 is accommodated in the space 49. On the other hand, the lever portion 60 of the slider 56 is exposed to the outside through the cutout portion 42 formed in the outer wall portion of the receiving member 40. The receiving member 40 is later accommodated in the annular frame 66, but here again, as in the case of the reinforcing plate 80, the cutout portion 42 protruding from the receiving member 40 has an outer wall portion ( The housing member 40 can be accommodated in the annular frame 66 in a predetermined direction by inserting it into the cutout 73 formed correspondingly to 68, and the housing member 40 is accommodated in the annular frame 66. After that, the housing member 40 can be held in a predetermined direction with respect to the annular frame 66. The receiving space formed by the receiving member 40 and the reinforcing plate 80 when the receiving member 40 is accommodated in the annular frame 66, and the cutout 42 of each of the receiving member 40 and the annular frame 66. Only the lever portion 60 of the slider 56 is exposed from the cutout portion 73, and the main body portion 61 having the locking portion 65 is flexibly received in the receiving space. In addition, as is apparent from the cutout portion 42 of the housing member 40, the shape of the slider 56, and the like, the flow direction of the slider 56 includes the outer wall portion of the housing member 40 or the annular frame 66 ( 68 is a direction orthogonal to the cutout 73 formed in the cut portion 73, that is, the longitudinal direction of the slider 56 (arrow B direction in FIG. 3).

After the receiving member 40 is accommodated in the annular frame 66, the six fixing pieces 74 protruding from the outer wall portion 68 of the annular frame 66 are corresponding cut portions 41 of the receiving member 40. Are each bent towards. As a result, the housing member 40 can be fixed to the annular frame 66.

The slider 56 in the receiving space, in particular its locking portion 65, can freely move its position by operating the lever 60. Therefore, there is no fear that the locking portion 65 will remain dead in the accommodation space, and even if it is in such a state, such a state can be simply released by moving the lever portion 60. In response to the movement of the lever portion 60, the locking portion 65 of the slider 56 is moved back and forth of the guide 69 through a cutout 72 provided in the guide 69 of the annular frame 66. In other words, the magnetic sleeve, which may be disposed inside the guide 69, approaches or collides with or moves away from the cylindrical sleeve 26 of the first assembly. However, since the access and the suction to the cylindrical sleeve 26 are naturally made by the magnetic action of the cylindrical sleeve 26, the original meaning of forming the lever portion 60 is the locking portion from the cylindrical sleeve 26. It is to keep 65 away. In order to facilitate the operation of the slider 56, the handle portion 62 is formed at the tip of the lever portion 60 by bending or drawing.

In order to act the magnetism of the first assembly, the slider 56 may be formed of a magnetic body or a nonmagnetic body. Only the locking portion 65 of the slider 56 has to be formed of a magnetic material among the constituent members of the second assembly. When one slider 56 is formed of a nonmagnetic material, magnetic plating is performed on the locking portion 65, or the locking portion 65 is covered with a magnetic material, and the locking portion 65 is substantially made of magnetic material by other means. You may also do it. In the case where the slider 56 is not molded in one piece, the entirety of the slider 56 does not necessarily have to be a magnetic material. It is good to form only the locking part 65 adsorb | sucked to a 1st assembly as a magnetic body, and the other part may be set as a separate body which is a nonmagnetic body. Depending on the design, the lever sleeve may be formed in one or both of the locking portion 65 or the main body portion 61, and the cylindrical portion may be pushed or pulled by moving the lever portion. 26 may be kept away from the locking portion 65. What you do with it is the freedom of the designer. Here, some care must be taken when the entirety of the slider 56 is formed of a magnetic material. This is because, in the slider 56 formed entirely of magnetic material, all portions other than the locking portion are attracted to the first assembly. When the portion other than the locking portion is attracted, the locking by the locking portion cannot be made impossible or smooth. Therefore, research for adsorbing the locking portion 65 to the cylindrical sleeve 26 more reliably is necessary. Here, in the hole provided in the center of the slider 56, the locking portion 65 of the slider 56 protrudes toward the side where the cylindrical sleeve 26 of the first assembly is disposed, that is, the direction approaching the hole. A portion other than the locking portion, particularly the portion on the opposite side of the locking portion 65, is deeper indented toward the side farther from the cylindrical sleeve 26 of the first assembly, that is, the direction farther from the hole. As described above, the slider 56 is substantially symmetrical, and moves only in the longitudinal direction. Thus, by forming such a shape, the magnetism acting on the locking portion 65 is transferred to a portion other than the locking portion 65. It can be made larger than the working magnet. The locking portion 65 can be reliably adsorbed to the cylindrical sleeve 26 of the first assembly by the self-shielding action of the guide 69 of the annular frame 66 together with the structure of the locking portion 65. have. However, the cutting in the slider 56 is not always necessary, and in some cases, the locking portion 65 can be reliably adsorbed to the cylindrical sleeve 26 only by the magnetic shielding action by the guide 69. The design of the locking portion, the lever portion, and the slider is free.

The fixing piece 48 is fixed to the receiving member 40, the shape of which is almost the same as the fixing piece 14 fixed to the annular plate 10. That is, the fixed piece 48 is comprised from the annular part 52 and the two fixed parts 54 extended from both sides of this annular part 52 upward. The annular portion 52 is used for fixing to the receiving member 40, and the fixing portion 54 is used for fixing the second assembly to an object such as a handbag. In addition, the fixing piece 48 may be formed in one piece with the housing member 40 similarly to the fixing piece 14 fixed to the annular plate 10. However, the hole 50 of the fixing piece 48 fixed to the accommodation member 40 is different in size from the hole 20 of the fixing piece 14 fixed to the annular plate 10. The hole 50 of the fixing piece 48 fixed to the receiving member 40 is not necessarily necessary and may be omitted. However, in the case where the hole is formed, the retaining pin 34, in particular, the head 38 thereof. Since the part of) can be put there, there is an advantage that the thickness of the first assembly and the second assembly can be made thinner.

The operation of the receiving member 40 is as described above. The material does not bury the magnetic material, non-magnetic material. In any case, the function as the receiving member 40 can be achieved. An annular protrusion 43 is formed in the housing member 40 toward the outside, and an annular recess 45 is formed around the protrusion 43. The projection 43 and the recess 45 and the catch position with a predetermined position of the housing member 40, the engagement piece 48, and is used to facilitate fixed in a fixing piece (48). That is, when the fixing piece 48 is fixed to the receiving member 40, as is apparent from FIGS. 1 to 3, the hole 50 of the fixing piece 48 is inserted into the protrusion 43 of the receiving member 40. And inserting the annular portion 52 of the fixing piece 48 into the recessed portion 45 of the accommodation member 40 formed in a shape corresponding to the annular portion 52, and the projection 43 is accommodated in the accommodation member ( The fixing piece 48 can be reliably fixed to the predetermined position of the accommodating member 40 by caulking to the outer side of the hole 46 of 40. As shown in FIG.

As described above, the housing member 40 is formed with an annular step 47 corresponding to the step 84 formed by the guide 69 of the annular frame 66. These steps 84 and 47 have a substantially complementary shape, and are aligned with each other to increase the strength in the vertical direction. By fitting these, the hole 46 of the accommodation member 40 and the hole formed inside the guide 69 of the annular frame 66 can be reliably aligned. When their holes are aligned, little gap is formed between them, so that when the first and second assemblies are combined, the head 38 of the locking pin 34 of the first assembly is not caught and their assembly is Are combined seamlessly.

Next, the operation of the lock in the combination of the first assembly and the second assembly will be mainly described with reference to FIG.

The combination of the first assembly and the second assembly is achieved by the magnetic action between the plurality of parts of the first assembly and the second assembly. When the first assembly and the second assembly approach each other and the distance is shortened to some extent, by the magnetic action between the slider 56 and the first assembly, or the annular frame 66 or the reinforcing plate 80 is formed of a magnetic body. If so, these assemblies are instantly combined by the magnetic action between the slider 56, the annular frame 66, and the reinforcing plate 80 and the first assembly .

When the first assembly and the second assembly are combined, the front surface 31 of the cover of the first assembly (the front surface 21 of the magnet when the cover is not installed) is adsorbed with the front surface of the annular frame 66 of the second assembly. In addition, the locking pin 34 and the cylindrical sleeve 26 protruding from the upper portion of the first assembly are inserted into the alignment holes of the second assembly. At the same time, the circumferential portion of the head 38 of the locking pin 34 reaches near the tip of the guide 69 of the annular frame 66 of the second assembly, and the tip of the cylindrical sleeve 26 receives the receiving member ( It passes almost completely through the closed receiving space between 40 and the annular frame 66.

In this magnetic lock, the first assembly and the second assembly are combined, and at the same time, the combination of these assemblies can be automatically locked. The automatic lock is precisely due to the cooperative magnetic action between the magnet 22, the cylindrical sleeve 26, and the annular frame 66, and the locking portion 65, but mainly the cylindrical sleeve 26 and the system. This is due to the magnetic action between the branches 65. The magnet generated by the magnet 22 is generated in the cylindrical sleeve 26 via the annular plate 10. As a result, the slider 56 located in the vicinity of the cylindrical sleeve 26, in particular, the locking portion 65, is attracted to the outer periphery of the cylindrical sleeve 26 that has been magnetized. When the locking portion 65 of the slider 56 is adsorbed to the cylindrical sleeve 26, the alignment holes of the second assembly are narrowed by the locking portion 65, and as a result, the first assembly and the second assembly are coupled. Even if it is to be removed, the locking portion 65 and the locking pin 34, in particular, the rear surface of the head 38 collide with each other to fit each other, so that the engagement cannot be released. That is, the first assembly and the second assembly are automatically locked. This point will be described in detail with reference to FIG.

Here, the description is added to the function as those yokes which are exhibited only when the annular frame 66 or the reinforcing plate 80 is formed of a magnetic body. When the first assembly and the second assembly are combined by the above-described magnetic action, as is apparent, magnetism by the magnet 22 of the first assembly is generated in the annular frame 66 or the reinforcing plate 80 of the second assembly. In addition, since the slider 56 is attracted to the annular frame 66 or the reinforcement plate 80 as well as the cylindrical sleeve 26, the locking portion 65 of the slider 56 is the cylindrical sleeve 26 There is also the question of whether or not to be adsorbed smoothly). However, by forming an annular frame 66 or the reinforcing plate 80 is a steel magnetic material (magnetic material) of the season back, in other words by making them function as a yoke This problem can be overcome.

This principle can generally be thought of as: For convenience of explanation, it is assumed here that the magnetic pole on the annular plate 10 side of the magnet 22 is the S pole and the magnetic pole on the opposite side is the N pole (in the case of reverse polarity, the same can be considered. ) As is apparent, the S pole The magnetism from the surface is gathered near the tip of the cylindrical sleeve 26 by the action of the annular plate 10 and the cylindrical sleeve 26 functioning as a yoke to generate the strongest magnetic force in the vicinity of these tips. On the other hand, the magnetic is generated, the flow of self-moyeojyeo near the outer periphery of these members by an annular frame 66 or the reinforcing plate 80, which functions as a yoke toward the S-pole from the outer circumferential portion near from the N-pole. Therefore, the magnetic field is weakened by the amount that flows out to the outer circumference in the portion other than the outer circumference of the annular frame 66, that is, the portion other than the outer circumference of the annular frame 66 including the portion where the slider 56 is disposed. The magnet attracting (56) is also weak. As a result, the direction of the magnetic force in the vicinity of the distal end of the cylindrical sleeve 26, which has collected the magnetism at almost one point, becomes larger than the magnetic force in the annular frame 66 in which the magnetic force decreases by the amount of the magnetic flow. Since 65 is larger than the magnetic force in the annular frame 66, the locking portion 65 is smoothly attracted to the cylindrical sleeve 26 having a larger magnetic force despite being attracted to the annular frame 66. In addition, the above does not mean that the annular frame 66 or the reinforcing plate 80 must be formed of a magnetic body, but it can be considered as one effective effect when these are formed of a magnetic body.

Other structures may be used to smoothly adsorb the slider 56 to the cylindrical sleeve 26. Another method is to provide a magnetic gap member formed of a nonmagnetic material between the slider 56 (particularly, the locking portion 65 thereof) and the magnet 22. For example, a non-magnetic material having a thickness of 0.01 to 10 mm, depending on the strength and size of the magnet, the shape and area of the locking portion 65 with respect to the cylindrical sleeve, and the moving distance or cooperative magnetic action with other members. By placing the magnetic gap member made of an adult between the locking portion 65 of the slider 56 and the magnet 22, the slider 56 can be smoothly attracted to the cylindrical sleeve 26. This was demonstrated by the experiment of this inventor. Instead of providing the magnetic gap member, the slider 56 itself, the magnet 22 itself, and any member between the slider 56 (particularly its locking portion 65) and the magnet 22 are non-magnetic. The same effect can be obtained also by plating of the material. The thickness of the plating can be adjusted to various thicknesses in accordance with the time to penetrate the plating liquid, and therefore, the same effect as above can be obtained by plating the slider 56 with an appropriate thickness. Incidentally, there is no conventional installation of such a nonmagnetic magnetic gap member. For example, as disclosed in Japanese Patent Application Laid-open No. 50-112170 by the applicant of the present application, a magnet cover made of a nonmagnetic material provided to protect the magnet is consequently between the magnet 22 and the slider 56. Although it may look like a magnetic gap member, these conventional examples are not intended to actively use this nonmagnetic magnetic cover as a tool for smoothly moving the slider 56. Moreover, at the time of filing of the above-mentioned Japanese Patent Application No. 50-112170, there was only a fragile magnet such as, for example, a ferrite magnet, and it was necessary to install a magnet cover for protecting the magnet. The magnet cover disclosed in Japanese Patent Application Laid-Open No. 50-112170 is also provided for such a purpose, and is not intended to be used as a tool for smoothly moving the slider 56 as in the present invention. The applicant of this application confirmed for the first time by such experiment that even such a nonmagnetic material can be used as a magnetic gap member for smoothly moving the slider 56 depending on the thickness. The nonmagnetic magnetic gap member may be combined with a magnetic body or a magnetic body plating. In addition, other nonmagnetic magnetic gap members may be considered to be coated, plastic members, and the like. In addition, a space may be used instead of the magnetic gap member. Their design is free.

In relation to the above-described principle, in this magnetic locking mechanism, the operation of setting the position of the slider 56 to the unlocked position before combining the first assembly and the second assembly is not necessary. That is, in the magnetic locking mechanism, even when the locking portion 65 of the slider 56 blocks the alignment hole of the second assembly, that is, the lock position, when the first assembly and the second assembly are combined, the lock assembly is described above. According to one principle, since the force to which the slider 56 is attracted to the annular frame 66, the reinforcement plate 80, or the magnet 22 is small, the locking portion 65 and the locking pin 34 as described above. Since the frictional resistance between the head 38 of the head 38 is small, the slider 56 is locked through the collision between the portion of the head 38 of the first assembly, in particular the locking pin 34, and the locking portion 65. It naturally falls easily from the location. In this case, the locking portion 65 is once again detached from such a position, and is again automatically adsorbed to the cylindrical sleeve 26, so that the lock can be completed automatically. Therefore, in this self-locking lock, the operation for setting the position of the slider 56 to a predetermined position, i.e., the unlocking position, before combining is unnecessary.

4 is a cross-sectional view taken along the line A-A of FIG. This figure clarifies the positional relationship between the slider 56 and its peripheral parts at the locked position and the unlocked position. Fig. 4A shows the positional relationship at the lock position, and Fig. 4B shows the positional relationship at the lock release position.

As apparent from Fig. 4A, in the locked position, the locking portion 65 of the slider 56 is in a position adsorbed to the outer circumferential surface of the cylindrical sleeve 26. As shown in Figs. As a result, even when the combination of the first assembly and the second assembly is to be released (that is, even when the locking pin 34 or the like is moved vertically downward in the drawing), the locking pin 34 indicated by the two-dot chain line is shown. This head 38 collides with the locking portion 65 of the slider 56, so this lock cannot be released.

In order to release this lock, as shown in (b), the locking portion 65 must be moved at least outside the outer circumference of the head 38 of the locking pin 34. The locking portion 65 can be moved by moving the slider 56 in the direction of the arrow in the figure. By moving the slider 56 in the direction of the arrow, the locking portion 65 is pushed outward from the outer circumference of the head 38, so that the collision between the locking pin 34 and the locking portion 65 is released. That is, the lock is released. Then, the magnetism from the first assembly substantially acts on the locking portion 65 of the slider 56 before and after the lock is released. This is due to the shape of the slider 56 described above and the magnetic shield function of the guide 69 of the annular frame 66.

Next, an example of use of the magnetic lock of the present invention will be described with reference to FIG. The magnetic locking device of the present invention can be used for each case, door, and various other objects such as a handbag or a bag, a landel, a look, a belt, a cigarette, an attachment case. Here, the handbag will be described as an example. Fig. 5 shows the first assembly and the second assembly fixed to the handbag in a side view with a partial enlargement of the handbag.

According to this embodiment, the first assembly and the second assembly are respectively fixed to the front side of the main body 4 of the handbag and the rear side of the lid 3. On the contrary, the first assembly may be fixed to the lid 3 of the handbag and the second assembly to the main body 4 of the handbag, respectively.

These assemblies are fixed in a predetermined position by fasteners provided in each assembly. As described above, these fasteners have two fastening portions 18 and 54 (as well shown in Figs. 1 and 2), but correspond to the fastening portions of the main body 3 and the lid 3, respectively. In each case, a set of holes (not shown) are formed to penetrate the fixed portion. After each of the fixing portions 18 and 54 is completely pressed into these holes, each of the fixing portions is bent by bending with a hammer or the like toward the outside (slightly the inner side) to thereby bend the first assembly and the second assembly into the main body 4, respectively. ) And the lid 3 can be fixed. As described above, the second assembly is strengthened in the vertical direction by the guide 69 of the annular frame 66, so that it is not destroyed or deformed by this fixing operation.

In general, washers 6 and 5 are disposed between the fixing portion 18 and the main body 4 and between the fixing portion 54 and the lid 3 so that these fixings can be performed more reliably. These washers 6 and 5 are provided with the same holes corresponding to the holes formed in the main body 4 and the lid 3. In the case of using a washer, the respective fixing portions 18 and 54 of the fasteners are sequentially passed through the holes of the body 4 and the washer 6 or the holes of the lid 3 and the washer 5, respectively. It is good to bend. In addition, as the method of fixing the first assembly and the second assembly to a handbag or the like, caulking, screws, or other methods may be used in addition to using the fixing pieces 14 and 48.

When the first assembly and the second assembly fixed to the main body 4 and the lid 3 are combined, that is, when the lid of the handbag is locked, the first or second assembly is the main body 4 and the lid of the handbag. It is preferable to be located between (3) and to make it hardly visible from the outside. The release of the first assembly and the second assembly can be performed by inserting a finger into the gap between the main body 4 and the lid 3 and pressing the knob 62 of the slider of the second assembly. In order to facilitate this operation, the handle 62 of the second assembly is preferably fixed to the vicinity of the edge 7 of the lid 3 or the same position as shown in the drawing. good. Further, as another release method, a method of fixing the lever of the second assembly to the handbag and pressing the handbag portion having the lever fixed therein can also be considered. Although not shown in the drawing, the main body 4 and the lid 3 are formed by stitching at least two leathers or envelopes together, and the bent portions of the respective fixing portions 18 and 54 are disposed between the two members. Located. Therefore, these fixing parts are not visible from the outside. In addition, when the handle portion 62 is in the same position as the edge portion 7 of the lid 3, the handle portion 62 becomes obstructed and cannot be sewn with a sewing machine or the like. In order to solve this, when the fixing part 54 is fixed at the predetermined position of the lid 3, only the second assembly, that is, also including the lever part 60 or the handle part 62, rotates about 90 degrees from the right to the left. If the structure (not shown) can be sewn with a sewing machine. Then, the second assembly including the handle portion 62 may then be returned to a predetermined position.

According to the above fixing method, when the first assembly and the second assembly are combined, their assemblies can not be substantially exposed to the outside, so the magnetic locks can make various ornaments (not shown) according to the desired part of the handbag. Can be. Therefore, there is no problem that the design is determined by the locking mechanism or the user's preference cannot be sufficiently reflected.

Although the use example of the magnetic locking device of the present invention has been described by taking a handbag as an example, the magnetic locking device of the present invention is not limited to a handbag, but each case or door such as a bag, a randcell, a look, a belt, a cigarette, an attachment case It can be used for various objects requiring a lock, such as a knob. Therefore, the object using the magnetic lock of the present invention is not limited.

In each of the above embodiments, when the parts are formed of a nonmagnetic material, for example, the parts formed of the magnetic material may be plated with the nonmagnetic material to achieve the same effect as the parts formed of the nonmagnetic material. have. Therefore, in each embodiment, the member to be formed of the nonmagnetic material may be replaced with the magnetic member which has been plated with the nonmagnetic material or the magnetic member covered with the nonmagnetic material. In addition, the magnetic material can be plated with a magnetic material or covered with a magnetic material to exhibit an effect as a magnetic material. Plating may be carried out using, as the anti-rust wihaeseodo addition, decoration to the part 1 and the entire surface of each of the components of a non-magnetic material or magnetic material. In particular, the usage is considered to be effective in the case where only a part of the member, for example, the engaging portion 65 of the slider is made of magnetic material. In the above embodiment, the magnet does not necessarily need to be installed in the first assembly, but may be provided in the second assembly. For example, there is a method of disposing the magnet between the annular frame and the reinforcing plate of the second assembly, and the magnet 22 may be provided between the slider 56 and the annular plate 10 without the annular frame. . The magnets 22 may be plastic magnets or other magnets, and may be plated on these magnets. And other methods can be thought of. In addition, although almost cylindrical shape as a whole sphere magnetic lock of the invention, not necessarily in a cylindrical shape, for example as a whole may be in a tubular shape of a rectangle, oval, or other various shapes. Many other changes will be apparent to those skilled in the art.

As described above, the annular plate 10 does not have to be formed of a magnetic material, but may be formed of a nonmagnetic material. As is apparent, when the annular plate 10 is formed of a nonmagnetic material, it cannot be fixed to the magnet or the cylindrical sleeve 26 by the magnetic action of the magnet 22, but they are welded, adhesive material, and caulking. , Screws and many other methods are sufficient. The same applies to the case where the fixing piece 14 is attached to the magnet.

The head 38 is preferably formed of a nonmagnetic material as described above. However, the head 38 is not necessarily formed of a nonmagnetic material and may be formed of a magnetic material.

In addition, the cylindrical sleeve 26 of the first assembly does not necessarily have to penetrate the closed receiving space between the receiving member 40 and the annular frame 66 when the first assembly and the second assembly are combined, but the slider 56 It is enough to reach the neighborhood of). Even in this case, the slider 56 can be moved to the locked position by the magnetic action from the cylindrical sleeve 26.

As described in the related art, when the annular protrusion is provided on the second assembly, the appearance is damaged, but in addition to the guide 69, it is possible to more effectively prevent the lateral difference between the first assembly and the second assembly. .

For example, the circular edge 66 of the annular frame 66 of the second assembly shown in FIG. 3, that is, the annular protrusion projected outwardly (outward) toward the combination direction with the first assembly on the side of the suction surface 67. That is, when the first assembly and the second assembly are combined to form an edge-shaped guide, the edges of the first assembly are not provided by the edge-shaped protrusions (the cover 30 or the cover 30 in the example of the embodiment). When not in use, the transverse difference between the first assembly and the second assembly can be prevented by combining them in such a way as to cover the circular edge of the magnet 22 from the outside.

In other words, instead of providing the guide 69, only such edge-shaped protrusions can be provided to prevent the lateral difference between the first assembly and the second assembly. For example, in the second assembly, the edges of the edge-like protrusions, that is, the edges in the orthogonal direction (the first assembly and the second assembly are combined directions) with the front surface of the second assembly (the annular frame 66 in the example of the embodiment). The height of the protrusion of the protruding part of the shape is determined by the height of the locking pin 34 in the first assembly, that is, the first assembly (eg, the cover 30 in the example of the embodiment) in the orthogonal direction (combination direction of the first assembly and the second assembly). Alternatively, when the cover 30 is not provided, the protrusion height of the locking pin from the front surface of the magnet 22 is substantially equal to or larger than that of the first assembly and the second assembly, so as to be equal to or greater than that between the first assembly and the second assembly. Since the position of the first assembly is defined by the edge-shaped protrusion of the two assemblies, it is possible to prevent the side difference between the first assembly and the second assembly without providing the guide 69. However, the height of this edge-shaped protrusion can be set freely by design.

Hereinafter, refer to FIG. 6 to FIG. 8, it will be described In the edge-shaped projections and more particularly such. Each of these figures shows a magnetic lock as a cross-sectional view of a center line similar to that of FIG. 3, and the numerals in the figures indicate a member equal to or equivalent to the member indicated by FIGS. However, these guides (FIGS. 2 and 3 (69)) described above in FIGS. 6 to 8 are not shown.

6 shows an example in which edge-shaped protrusions 33 are provided in the first assembly , and magnets 22 are similarly provided in the first assembly. In this embodiment, the edge-shaped protrusion 33 is formed in the cover 30. When the first assembly and the second assembly are combined, the edge-shaped protrusion 33 provided on the side surface of the adsorption surface 31 of the first assembly includes the adsorption surface 67 of the second assembly inside. It is guided along the side surface 66a of the adsorption surface 67 of the second assembly. In addition, after the first assembly and the second assembly are combined, the edge-shaped protrusion 33 of the first assembly covers at least a part of the side surface 66a of the adsorption face 67 of the second assembly from the outside. When combining the first assembly and the second assembly by the configuration or after combining them, it is possible to effectively prevent the lateral difference between the first assembly and the second assembly. In the illustrated example, the edge-shaped protrusion 33 is formed by punching and drawing the magnet cover 30, but it is not necessary to do so. For example, an edge-shaped protrusion (not shown) may be provided on the main body of the magnet 22 without providing a magnet cover (not shown), or other methods may be used. The magnet 22 may be a plastic magnet or may be plated on the plastic magnet.

In particular, as in the embodiment shown in Fig. 6, when the magnets 22 and the edge-like protrusions 33 are installed in the same assembly, an effect that cannot be obtained when they are not installed in the same assembly can be obtained. In order to clarify this effect, it is assumed that the first assembly and the second assembly are not combined. In such a state, in particular, when a magnetic card such as a credit card or a train ticket is brought close to the assembly on the side where the magnet is installed, the magnetic card is usually destroyed by the magnetic action of the magnet provided in the assembly. However, by providing the edge-shaped protrusions 33 in the assembly, when the magnetic card collides with the edge-shaped protrusions 33, the magnet 22 can no longer be approached, thereby preventing or preventing the magnetic card from being destroyed. Then, the magnetic action of the, as generally apparent can be obtained a sufficiently high effect in the distance such as this, because decreases in inverse proportion to the square of the spacing distance.

In contrast to the above, the embodiment of Fig. 7 shows an example in which the edge-shaped protrusion 75 and the magnet 22 are provided in the second assembly. In this embodiment, however, unlike in Fig. 6, the edge-shaped protrusion 75 is provided on the annular frame 66, not the cover. Here, too, since the magnet 22 and the edge-shaped protrusion 75 are provided in the same assembly, it is possible to effectively prevent or prevent the destruction of the magnetic card as in the embodiment of FIG. In addition, as in the embodiment of Fig. 6, in this embodiment, when the first assembly and the second assembly are combined, the edge-shaped protrusion 75 provided on the side surface of the adsorption face 67 of the second assembly has a first inside thereof. Guided along the side surface 10a of the adsorption surface 11 of the assembly, and after the first assembly and the second assembly are combined, the edge-shaped protrusion 75 of the second assembly is the side surface of the adsorption surface 11 of the first assembly. At least a part of (10a) is covered from the outside. Therefore, the transverse difference between the first assembly and the second assembly can be effectively prevented when the first assembly and the second assembly are combined or after they are combined. In particular, the example shown in the edge-shaped projections (75) be provided for edge-shaped projections of the annular frame 66 but is to be formed by rowing a punching DE, it is with him to, it is not necessary to do other methods good. 7, the member indicated by the reference numeral 13 is a magnetic gap member.

In the embodiment of Fig. 7, by providing the edge-shaped protrusions 75, the following effects can be obtained in addition to preventing the lateral difference. That is, when the first assembly and the second assembly are combined, the assembly is approached with a somewhat out of state (as described with reference to FIG. 5, when the magnetic locking device of the present invention is used for the main body and the lid of the handbag, and so on. The same state occurs many times) The head 38 of the engagement pin 34 of the first assembly does not easily enter the hole 71 of the annular frame 66, and the front surface of the annular frame 66 (adsorption surface ( 67)), but even in such a case, in the present invention, since the edge-shaped protrusion 75 is provided, the head 38 of the locking pin 34 of the first assembly has an inner side of the edge-shaped protrusion 75. Once inside, the head 38 of the retaining pin 34 can easily be guided into the hole 71 of the annular frame 66 by only slightly deviating the assemblies (body and lids of the handbag). Therefore, in the edge-shaped projections (75) there is an effect that it is possible to facilitate the combination of the first assembly and the second assembly.

8 corresponds to a combination of the embodiment of FIG. 6 and the embodiment of FIG. That is, the edge assembly protrusion 75 is provided in the second assembly while the magnet 22 is provided in the first assembly . In this case, unlike FIG. 6 or FIG. 7, there is no advantage of preventing or preventing the destruction of the magnetic card, but the transverse difference between the first assembly and the second assembly can be effectively prevented. 8 has the advantage of facilitating the combination of the first assembly and the second assembly by the edge-shaped protrusions 75 as in the embodiment of FIG.

In the embodiment of Fig. 8, in the case where the annular frame 66 is formed of a magnetic material in particular, by providing the edge-shaped protrusions 75, it is possible to obtain an effect of increasing the adsorption force between the first assembly and the second assembly. In order to explain this, it is assumed that the N pole and the S pole are arranged on the upper side of the magnet 22 in FIG. 8 (the reverse arrangement can also be considered). In this case, the magnetism from the upper N pole is led to the S pole side through the annular frame 66 as indicated by the arrow or the arrow shown. At this time, in the present invention, since the edge projections 75 are provided, the magnetism is guided from the N pole side to the top portion 75a of the edge projections 75 to propagate the air in the air from the top portion 75a. It descends toward the outer side downward and passes through the annular plate 10 of the first assembly to reach the S pole side. By providing the edge-shaped protrusions 75 in this way, the flow of magnetism from the N pole side can be effectively passed through both the first assembly and the second assembly, and a stronger magnetic force can be generated therebetween. Therefore, by providing the edge-shaped protrusions 75, the effect of increasing the adsorption force between the first assembly and the second assembly is obtained.

Moreover, this edge-shaped protrusion part 75 also has an effect which makes the annular frame 66 harder. That is, by providing the edge-shaped protrusions 75, the strength of the annular frame 66, in particular, the strength to the torsion can be increased. Since the annular frame 66 is made of a relatively thin plate, this effect can be said to be very important. As described above, there is a significant effect in providing the edge-shaped protrusions 75, and it is somewhat aesthetically bad but can be said to have an effect of supplementing it.

In contrast to the embodiment of FIG. 8, the embodiment of FIG. 9 is an example in which the edge-shaped protrusion 33a is provided in the first assembly and the magnet 22 in the second assembly. In this case as well, the same effects as described above can be obtained. And the same code | symbol as the former is attached | subjected to the member same as or equivalent to the member enumerated above.

10 illustrates another embodiment for preventing the lateral difference between the first assembly and the second assembly in the same manner as in FIGS. 6 to 9.

10 shows an example in which the annular expansion guide portion 27 is provided below the first assembly, particularly the cylindrical sleeve 26. The outer diameter of the expansion guide portion 27, that is, the outer diameter in the direction orthogonal to the combination direction of the first assembly and the second assembly (intersecting) is substantially the same size as the outer diameter of the locking head 38 at the distal end, and the cylindrical sleeve It is set larger than the outer diameter of the part of (26). Corresponding to the expansion guide portion 27, the outer diameter of the hole of the second assembly, particularly near the inlet portion, is substantially slightly larger than the outer diameter of the locking head 38 or the expansion guide portion 27. When the first assembly and the second assembly are combined or after they are combined, the expansion guide portion 27 of the first assembly is caught near the inlet of the hole of the second assembly to effectively prevent the lateral difference between those assemblies. . And the outer diameter of the lower side of the cylindrical sleeve 26 does not necessarily need to be substantially the same as the outer diameter of the engagement pin 34, and if it is set larger than the outer diameter of the locking head 38, the same effect can be acquired. For example, although not shown in particular, the same effect as above when the cylindrical sleeve 26 is conical and the outer diameter of its largest bottom is substantially equal to or larger than the outer diameter of the locking head 38. Can be obtained. In addition, the extension guide part 27 does not necessarily need to be annular, and may be a rectangle, rod shape, or any other shape.

Finally, another embodiment of the slider 56 of the present invention will be described with reference to FIG. The slider 56a shown in Fig. 11 and the slider 56 described above with reference to Figs. 1 to 5 differ only in the shape of the lever portion 60a, and all other shapes are the same. In other words, the handle portion 60a of the slider 56a of this embodiment is not provided with a handle portion, and instead, a hole 87 for attaching the extension member 86 is formed.

By attaching the extension member 86 to the slider 56a, the lever portion 60a of the slider 56a can be substantially extended. The extension member 86 is required, for example, when the assembly, especially the second assembly, is mounted at a position deeper than the edge 7 of the lid 3 as the distance between the lid and the body such as a handbag. As described above, the release of the lock of the first assembly and the second assembly is performed by pressing the lever portion of the second assembly by inserting a finger into the gap between the main body and the lid, but if the position of the second assembly is too deep, Because it becomes impossible.

The extension member 86 is formed of two sheets of metal, that is, an inner plate 88 and an outer plate 89. These sheet metals are each formed by punching, drawing, bending, etc., a thin metal plate, and are then fixed to each other as shown. The fixing between them penetrates the inside 94 of the inner plate 88 through the protrusion 94 facing the inner side of the outer plate and caulks there. Of course, other soldering, spot welding, or other methods may be used. Then, the distal end portion of the outer panel, but is cut in a slightly arcuate shape (95) towards the inside, and this may be a group as rudder shape matched to the outer circumference of the annular frame design (66).

In particular, you may plant in the vicinity of the front-end | tip part which contacts the connection part with the slider 56a. In this portion, an opening 90 for receiving the lever portion 60a of the slider 56a is formed. The size of the opening 90 is large enough to receive the lever portion of the slider 56a. The slider 56a is mounted therein by pushing the lever portion 60a into the opening 90, and can be removed therefrom by pulling the lever portion 60a out of the opening 90. However, once it is attached, you may not be able to remove it from there.

In the vicinity of the tip center of the inner plate 88 forming a part of the opening 90, projections formed by the pressing from the outside are formed inwardly (indicated by the recess 91 instead of the projections). When attaching the extension member 86 to the slider 56a, this protrusion 91 engages with the hole 87 formed in the symmetrical part of the slider 56a.

The central portion of the tip end portion of the inner plate 88 on which the projection 91 is formed can be elastically displaced by forming the cutout portions 92 on both sides thereof. By this displacement action, the projection 91 of the inner plate 88 is attached to the hole 87 of the slider 56a with a predetermined force and can be detached freely therefrom. In particular, the inner plate 88 may be formed of phosphor bronze in order to more effectively exert the detachment action of the extension member 86. However, it is not limited to this, and nonmetals, such as iron and other metals and plastics, can also be used. The material of the outer plate 89 is not particularly limited, but considering the strength, the inner plate 88 and the outer plate 89 are preferably formed of metal (brass, iron, or the like).

And, those skilled in the art can make it easily think of various embodiments of the combination described herein, but is also present as well as those of the configuration spreading.

According to the present invention, there is provided a magnetic lock that strengthens the strength of the assembly and can prevent the difference between the first assembly and the second assembly. Moreover, according to this invention, the structure for smoothly moving a locking material on a magnet is provided.
