Abstract

The fastener for jewelry has a pair of main body parts fixed to each other by a magnetic force at a free end of the jewelry. Each main body portion has an N pole and an S pole arranged in alignment along the longitudinal center line of the fastener, and magnetic poles having opposite polarities contact each other to hold the main body portion in a fixed relationship. One of the main body portions is provided with a safety device having a protrusion extending from the main body portion and partially overlapping with the other main body portion to hold the main body portions together. When the protrusion moves to the locking position, the other body moves along the longitudinal center line, shifts the magnetic means from the alignment relationship, and when the protrusion comes to the locking position, the magnetic means moves between them. Realignment is achieved by magnetic attraction, at which time a click that can be heard and / or sensed by the wearer occurs to confirm that the body portions are properly secured together.

Description

  The present invention relates to a jewelry, and more particularly to an improved fastener for connecting two free ends of a chain of jewelry to each other in a simple manner.

  Certain types of jewelry, especially women ’s jewelry, require that the fasteners be easy to handle and can be easily connected and disconnected so that the wearer can easily connect and disconnect the free end of the bracelet or necklace. And there is always a conflicting demand to ensure that the fasteners are closed so that they cannot be inadvertently lost and the accessory is lost.

  Even a young man who is well dexterous, it is difficult to fasten a necklace behind the neck or in most cases a bracelet that can only be fastened using one hand. This is many times more serious for the elderly and for many people with arthritis or similar illnesses that are mild but have limited hand use.

  Magnetic fasteners without safety devices are widely used in clothing accessories. However, manufacturers or retailers of expensive jewelry (gold jewelry, sterling silver jewelry or jewelry containing jewelry) rarely offer necklaces with magnetic fasteners.

  Expensive jewelry producers and wearers want to protect the jewelry with safety devices, but none of the currently available magnetic fasteners are considered practical. Such fasteners are difficult to close, unsafe to close, or difficult to open. Some of them look bad.

  Therefore, all three of the consumer's main demands: easy attachment / detachment, reliable holding of the accessory after closing (cannot be opened by pulling), and easy opening. There has long been a need for fittings for filling and other items. In addition to these functional requirements, it should be understood that fasteners do not detract from the overall appeal of the accessory, but rather increase its commercial value if it is attractive to complement.

  An example of a magnetic fastener is shown in US Pat. No. 3,664,298 to Nessar-Ivanovic. This shows a fastener with magnets arranged side by side across the center line of the parts that make up the fastener, and in order to combine the parts into a fastener It is necessary to connect these two parts by a socket structure having a special structure. This connection configuration seems to require a certain degree of dexterity for the wearer, and as a whole, the fastener may open when subjected to a force pulling in an oblique direction with respect to both end edges of the fastener. It seems.

  Accordingly, it is desirable for the fastener to have all of the above-described properties, and in addition to indicate to the wearer in some clear manner that the fastener has been effectively and completely closed. Also, one means of providing such a clear indication is to the wearer that the fastener is completely closed, and the danger that the fastener will open unexpectedly and the fastener opens unexpectedly is fundamental. A clear click action (an action that generates a click sound) that can be heard and / or perceived by the wearer, indicating that they have been automatically excluded.

  Thus, to join the free ends of jewelry that have features that overcome the deficiencies of existing fasteners described above, and that have the desired functional characteristics while at the same time providing an attractive appearance to the wearer. It would be desirable to provide a fastener.

  The present invention is a jewelry and other article that can be easily closed, can reliably protect the jewelry when closed, and at the same time can satisfy the long-standing requirements for the fasteners described above, which is easy to open. It relates to an improved fastener for.

  The fastener of the present invention includes two main body portions that are fixed to a free end of a necklace or bracelet and connected to each other to form the fastener of the present invention. Each body is provided with magnetic means for forming a magnetically attractive surface having both N and S poles. The main body is fixed by placing the magnetic attraction surfaces in contact with each other so that the N pole of one attraction surface is aligned with the S pole of the other attraction surface. The main body portions are strongly held by the magnetic attraction force.

  The magnetic poles of the magnetic means of each main body are arranged in a line along the longitudinal center line passing through the main body, and this center line is basically the line connecting the chains that are attached to the fastener and constitute the accessory. It is consistent.

  Furthermore, it can be pivotally attached to one of the body parts, between the release position and the locking position where its free end engages with the other body part so that the body parts do not separate from each other. There is a safety device that can be moved by.

  In one embodiment, the safety device has a protrusion that enters into a hole formed in the other body portion and firmly locks the two body portions, and in another embodiment, the safety device A protrusion having a tongue-like portion (lip) facing inward may be provided at the free end of the first lip, and this lip partially overlaps the other main body portion to firmly lock the two main body portions.

  In yet another embodiment, a first body portion and a second body portion having a pivotably mounted safety device with a protrusion having a lip formed inwardly at a free end. Provided, the first main body is shorter than the second main body. In such a safety device, when the lip of the protrusion is rotated to the locking position that partially overlaps the first main body portion, the lip first engages with the first main body portion, and this is connected to the magnetic means. Is moved along the longitudinal centerline formed between the magnetic poles, thereby causing some movement of the magnetic means and causing a shift between the north and south poles.

  As the safety device continues to move to the locked position, the lip passes through the end of the first body to free the first body and the first body is in a position where the magnetic means are aligned. Return quickly. This rapid movement of the magnetic means of the first body part causes a click action that can be sensed and / or heard by the wearer, so that the fastener is fully closed and the safety device is engaged. The wearer can clearly see that he did. Thereby, the wearer can confirm that the accessory is securely worn by the wearer.

  Therefore, in the fastener of the present invention, the magnetic poles are aligned in a straight line like a bracelet or an extension of the necklace by the dipole magnetic means, and only at that position, the N pole of one magnetic means is the other magnetic means. The wearer can easily connect the necklace and bracelet with one hand. Thus, the fasteners are properly and accurately aligned so that not only the appearance of the fasteners is more attractive, but also until the wearer senses a click and / or hears a click. Since the safety device can be locked by magnetic attraction just by tightening the tool between the fingers, the safety device can be locked more easily.

  On the other hand, when the safety device is in its locked position, the accessory is securely held, and even if someone tries to separate the body parts from each other by pulling the ends of the necklace or bracelet, In most cases, the jewelry itself will cut off in another position before the fasteners are removed. Also, it is virtually impossible for the fastener to come off due to some accident or being caught in something.

  On the other hand, the fastener of the present invention is easy to open and can be opened with one hand without looking at the fastener. In addition, the fastener can be made very flat and small in structure, so it looks good when worn, which is also a desirable feature from a cosmetic standpoint. This fastener can be made very thin because the magnetic means of each of the two body parts automatically align in the same direction as the necklace chain or bracelet, ie along the longitudinal centerline, It looks great on thin necklace chains and bracelets.

  In addition, there are no protrusions or safety devices with edges that could bite into the wearer's skin, and the fasteners are very versatile, very thin and small in width and delicate. It can be matched to elegant jewels, while it can be made large and wide to make it more acceptable to people with arthritis on their fingers or those who have difficulty handling small fasteners.

  These and other features and advantages of the present invention will become apparent in the following detailed description with reference to the drawings.

It is a side view of the fastener of the completed state of the Example of FIG.

  1 and 2 are top views of the two main body portions 12 and 14 constituting the fastener for jewelry according to the present invention. The main body parts 12 and 14 can be made of various materials, but are preferably made of the same metal material as that used for the accessory used for the fastener, for example, silver or gold. The body parts 12 and 14 have rings 16 and 18, respectively, which are used to attach fasteners in a conventional manner to a chain of jewelry that constitutes a bracelet, necklace or other item.

  Further, a magnetic means is embedded or fixed in each of the main body portions 12 and 14. As will be described later, the magnetic means is composed of magnets 20, 22, 24, and 26 fitted into recesses of appropriate shapes formed in the main body portions 12 and 14. These magnets are arranged at intervals along a longitudinal line extending between them, and the polarities of the magnets 20, 22, 24 and 26 are predetermined as will be described later.

  Further, a safety device 28 is rotatably attached to the main body 14. The safety device 28 comprises a protrusion 30 projecting outwardly from its free end, preferably substantially perpendicular to the safety device 28.

  FIG. 2 is a side view of the main body portions 12 and 14 and shows the directions and positions of the magnets 20, 22, 24, and 26. In FIG. 2, for example, the magnets 20 and 22 of the main body 12 are aligned to form a magnetic attraction surface 32, and the magnetic attraction surface 32 is a flat surface as a whole. Speaking of the polarity of the magnets 20, 22, for example, the magnet 20 has its N pole aligned with the magnetic attraction surface 32, ie, coplanar, while the magnet 22 has its S pole aligned with the magnetic attraction surface 32. That is, they are formed on the same plane. Accordingly, two magnets are arranged along a flat and flat magnetic attraction surface 32, and each magnet is arranged with opposite magnetic poles in the same plane as the magnetic attraction surface 32, that is, aligned. Has been.

  The orientation of the magnets in the main body portions 12 and 14 is such that the magnetic poles are along the longitudinal center line of the main body portions 12 and 14, that is, the longitudinal center line indicated by C in FIG. Extends longitudinally along the fastener from one ring 16 to the other ring 18 and is substantially aligned with a chain or other flexible member secured to the rings 16, 18 to form a necklace, bracelet or other article is doing.

  As another feature of the main body 12, a recess 34 is provided on the surface away from the magnetic attraction surface 32. The magnets 20 and 22 are embedded in the main body 12 in a form fitted into a pair of recesses 36 and 38 formed in the main body 12. The magnets 20 and 22 may be fixed in the recesses 36 and 38 by an adhesive, or may be fixed by a fixing method described later.

  The main body 14 has the same configuration. That is, the magnets 24 and 26 are fixed in the recesses 40 and 42 so as to form a flat and planar magnetic attraction surface 44 on the main body 14. However, in this case, the magnet 24 is arranged with its south pole aligned with the magnetic attraction surface 44, that is, in the same plane, and the magnet 26 is arranged with its north pole aligned with the magnetic attraction surface, that is, in the same plane. Yes. As shown, the safety device 28 is pivotally attached to the body 14 by a pivot 46 so that the protrusion 30 is located at the free end of the safety device 28 and is shown in FIG. It is possible to move from the position to the locking position where the main body 12 is engaged.

  Next, FIGS. 3 and 4 are a top view and a side view of the fastener for jewelry according to the present invention in a state of being connected, and the safety device 28 is in the locked position, and the protrusion 30 is in the recess 34. The main body parts 12 and 14 are firmly held by being fitted and fixed to each other.

  As can be seen from these figures, particularly FIG. 4, the magnets 20, 22, 24 and 26 are aligned with each other, the magnetic attracting surfaces 32 and 44 are in contact with each other, and the south pole of the magnet 24 is Since the N pole of the magnet 26 is aligned and in contact with the S pole of the magnet 22, the magnetic attraction surfaces 32 and 44 are in contact with the opposite polarity magnetic poles of each magnet. The magnetic attraction surfaces 32 and 44 are held by the magnetic attraction force of the magnets 20, 22, 24 and 26 because they are attracted to each other by contact.

  The magnets 20, 22, 24 and 26 and the other magnets described for other examples in this specification are dipole rare earth neodymium magnets, fired N45 strength, with maximum magnetic force in the thickness direction. This magnet has the largest magnetic force among magnets currently known of the same size, but the fastener design of the present invention works effectively with a magnet with a smaller magnetic force. To do. The magnet is preferably plated with nickel so that the appearance can be improved and surface wear or corrosion can be prevented.

  Accordingly, as can be seen from FIGS. 1-4, the magnets of each body portion 12, 14 are spaced along the longitudinal axis of the fastener, i.e., the longitudinal centerline, and are aligned with the chain of clothing. So that the mutual magnetic attraction of the magnets perfectly aligns the body parts 12 and 14 and the safety device 28 moves to its locked position so that the protrusion 30 fits into the recess 34. This fastener makes it easy to connect the two body parts 12,14.

  Similarly, the fasteners for separating the main body portions 12 and 14 can be easily released with only one hand. After returning the safety device 28 from its locked position to its released position, it is only necessary to pull the main body portions 12 and 14 in the opposite directions, thereby easily eliminating the magnetic attraction force. Leave. In order to allow the wearer to easily put on the safety device 28, a ball or a protrusion 35 is provided on the safety device 28 so that the wearer can easily move the safety device 28 using a fingernail. Also good.

  Next, referring to FIG. 5 to FIG. 8, there are shown diagrams corresponding to those described in FIG. 1 to FIG. 4, but in this embodiment, the individual magnets in the embodiment described above are shown. Instead, single multipole bar magnets 48 and 50 are used. However, the use of the magnetic means comprising the magnetic attraction surfaces 32 and 44 is basically the same as the case described with respect to the embodiment of FIGS. 1 to 4, and each of the bar magnets 48 and 50 has an N pole and an S As shown in FIG. 8, the magnetic poles of the bar magnets 48 and 50 are arranged so that the magnetic poles of the magnet 48 are aligned with the S pole and the N pole of the magnet 50, respectively. Further, as a matter of course, in order to accommodate and fix the bar magnets 48, 50, it is only necessary to provide one recess 52, 54 in each of the main body portions 12, 14. The advantage of a single multipole magnet is that it is easy to assemble and requires less integration area in the fastener structure of the present invention.

  In other respects, the embodiment of FIGS. 5-8 is the same as the embodiment of FIGS. That is, the magnetic pole direction of the bar magnet is along the longitudinal center line of the main body, the magnetic attraction surface is a flat plane, and the magnet itself is located in a recess formed on the surface. Alternatively, the magnet itself may be flat and flat, and may be mounted on the surface of the main body instead of being embedded, and the final magnetic attraction surface may be maintained flat.

  Reference is now made to FIG. 9, which is a top view of yet another embodiment of the present invention. Again, a first body portion 56 and a second body portion 58 are provided, each having a ring 60, 62 for attachment to the accessory chain. Also in this embodiment, single multi-pole bar magnets 64 and 66 are used. The bar magnet 64 has an N pole 68 and an S pole 70, and the bar magnet 66 has an S pole 72. An N (North) pole 74 is provided, and the magnetic poles of the bar magnets 64 and 66 are arranged so as to be positioned on the longitudinal center lines of the first and second main body portions 56 and 58.

  As can be seen from the figure, the N pole 68 and the S pole 70 of the first main body 56 are in the alignment relationship of FIG. 9 and the orientation when the first main body 56 and the second main body 58 are combined. , Respectively, are aligned with the south pole 72 and the north pole 74 of the second body portion 58, thereby generating a magnetic attractive force between the respective bar magnets 64, 66, and the first and second body portions 56, 58. Are pulled in the direction of each other and maintained in that state.

  As with the previously described embodiment, a safety device 76 is provided having a projection 78 extending outwardly at a substantially right angle from its free end. The protrusion 78 has an arcuate recess 80 so that it will not contact the ring 60 when the safety device 76 moves from the release position of FIG.

  Next, FIG. 10 is a side view of the fastener of the present invention. In this figure, bar magnets 64 and 66 form flat magnetic attraction surfaces 82 and 84 that are paired with each other. A safety device 76 is also shown having an inward lip 88 at the tip of the projection 78. In fact, the inwardly facing lip 88 is a bifurcated lip that will straddle both sides of the ring 60 when the fastener is in the closed locked position due to the arcuate recess 80 (FIG. 9). is there. The safety device 76 is attached to the second main body 58 so as to be rotatable about a pivot 90, and can be rotated between a locking position and a release position.

  Next, FIG. 11 is a side view of the fastener of the present invention in which the safety device 76 has moved from the release position of FIG. 10 to a point close to the locking position. Thus, in FIG. 11, the inwardly facing lip 88 engages the outer edge 92 of the first body portion 56, causing the first body portion 56 to be magnetically attracted and aligned from its normal orientation. Therefore, the bar magnets 64 and 66 are displaced from the aligned state, and the magnetic attractive force is weakened. The outer edge 92 can be positioned at any position by configuring the first body portion 56 to be somewhat longer than the second body portion 58.

  Thus, in the final locked position of the fastener shown in the side view of FIG. 12, the inwardly facing lip 88 rides over the outer edge 92 of the first body 56, thereby opening the first body 56. Then, due to the mutual attraction of the bar magnets 64 and 66, the magnetic poles of the bar magnets 64 and 66 are rapidly returned to the aligned position where they are completely aligned again. This rapid return generates a clicking sound that can be heard and / or felt by the wearer.

  Therefore, this click sound and / or sensing of the click motion is unintentionally disengaged when the fastener is fully coupled and the safety device 76 is in the correct locking position, thereby firmly coupling the fastener. Thus, the wearer can be sure that there is almost no risk that the accessory will be lost.

  In this embodiment, the removal or separation of the fasteners can be easily performed by two completely different means. For one, the fastener can be disconnected without releasing the safety device 28. As can be seen from FIG. 12, the first and second body portions 56, 58 cannot be pulled outwardly and disconnected because the inwardly facing lip 88 prevents it, but they are directed toward each other. Can be moved to cause an unaligned state of the magnetic means, whereby the first and second body portions 56, 58 can be easily separated.

  Therefore, the wearer simply pushes the ring 60 of the first main body 56 in the direction of arrow B, and the first main body 56 is moved laterally, that is, along the longitudinal center line C of the magnet (FIG. 9). It can be moved to shift the magnet. Since the magnetic attractive force is substantially lost, when the inward lip 88 is removed, the first body portion 56 is opened and can be freely moved downward and separated from the second body portion 58. Can do. Therefore, the fastener can be opened with one hand without actually observing the fastener.

  As another way to open the fastener, it should be understood that the wearer can pull the first and second body portions 56, 58 apart by moving the safety device 76 from its locked position to its released position. it can. As a means for assisting the wearer in operating the safety device 76, for example, the safety device 76 can be provided with a ball or a protrusion 93, whereby the user can use the fingernail to place the safety device in the release position. It becomes easy to move.

  Next, FIGS. 13 and 14 show the top and sides of a typical magnet that can be used in the present invention. As illustrated, the magnet 94 is formed with a hole 96 with a countersink 98. As previously mentioned, the magnets of the present invention can be secured to the body with an adhesive, but other techniques may be used to maximize assembly accuracy, uniformity and simplification. Used. As shown in FIGS. 13 and 14, the magnet has a countersunk hole in the center. However, when using a dipole magnet, the thickness of the magnet is about 0.76 mm, so it is difficult to form a hole with a countersink.

  In any case, in FIG. 15, the main body portion 100 has a recess 102 for receiving the magnet 94, and a pillar 104 extending upward from the central region of the recess 102 is provided as shown in the figure. . The column 104 is made of a flexible material, and the magnet 94 is inserted so that the column 104 enters the hole 106 when it is fully seated in the recess 102 when it is incorporated into the body 100. . When the magnet is inserted, the upper end of the column 104 is pressed into the countersink 98, and a flat surface is formed at the upper end of the magnet, while the magnet 94 is firmly fixed in the recess 102.

  Next, FIG. 16 shows the top surface of yet another embodiment of the present invention. Again, a first body portion 106 and a second body portion 108 are provided, each having a ring 110, 112 for attachment to a chain of jewelry. Also in this embodiment, a single multi-pole bar magnet 114, 116 is used, the bar magnet 114 has an N (North) pole 118 and an S (South) pole 120, and the bar magnet 116 is also S (South). ) Having a pole 122 and an N (North) pole 124, the two bar magnets 114 and 116 are arranged such that each magnetic pole is located on the longitudinal center line of the first and second body portions 106 and 108. .

  As shown in the drawing, in the aligned state of FIG. 16 and the arrangement state when the first main body portion 106 and the second main body portion 108 are combined, the N pole 118 and the S pole 120 of the first main body portion 106 are the first one. The magnetic main body 108 is aligned with each of the S pole 122 and the N pole 124 of the main body 108, and pulls the first and second main bodies 106, 108 together between the bar magnets 114, 116, thereby maintaining a magnetic attractive force that maintains the connection. Arise. On the upper surface of the second main body portion 108, a recess 126 for the purpose described later is formed.

  Similar to the embodiment described above, a safety device 128 is provided having a protrusion 130 extending outwardly at a substantially right angle from its free end. In FIG. 16, the safety device 128 is shown in the release position, and is movable between the locking position and the release position. It is rotatably attached to the side opposite to the position.

  Next, FIG. 17 shows a side view of the fastener of the present invention. In this figure, bar magnets 114 and 116 form flat, planar magnetic attracting surfaces 134 and 136, respectively. In addition, a metal plate 138 is attached to the safety device 128 along its inner surface 140, and as can be seen from the figure, when the safety device 128 is rotated to the locked position, the second body It faces the part 108. The metal plate 138 is made of a magnetic attraction material.

  Also in this case, in order to form a flat planar magnetic attraction surface, the bar magnets 114 and 116 are disposed in the recesses 142 and 144 formed in the first and second body portions 106 and 108, and the bar magnet The magnetic poles 114 and 116 are arranged along the longitudinal center line C of the first and second body portions 106 and 108.

  Next, FIG. 18 will be referred to with FIGS. 16 and 17. FIG. 18 is a side view of the fastener of the present invention in a state where the safety device 128 is moved from the release position of FIGS. 16 and 17 to the locking position.

  As shown in the side view of FIG. 18, when the fastener is in the final locked position, the safety device pivotally attached to the first body 106 is in the locked position. Thus, the protrusion 130 enters and is secured to the recess 126 of the second body portion 108 to hold the first and second body portions 106 and 108 firmly together.

  Similarly, as shown in FIG. 18, the bar magnets 114 and 116 are aligned with each other, the magnetic attracting surfaces 134 and 136 are in contact with each other, and the N pole 118 of the bar magnet 114 is in contact with the bar magnet 116. Similarly, since the south pole 120 of the bar magnet 114 is in direct alignment with and in contact with the north pole 124 of the bar magnet 116, the magnetic attraction surfaces 134 and 136 are magnetically attracted by the bar magnets 114 and 116. They are held firmly together by force. Therefore, in any of the examples, the magnetic attraction surfaces 134 and 136 are attracted in the directions of each other due to the contact of the magnetic poles of opposite polarities of the individual magnets.

  However, in this embodiment, the safety device 128 is magnetically attracted to the bar magnets 114, 116, preferably steel, and is firmly held in its locked position by a metal plate 138, and its magnetic attraction force is The safety device 128 is held in the locked position of FIG. Instead of the plate, a magnetically attractive material may be provided integrally with the safety device 128. The basic principle of attraction between the safety device 128 and the magnetic means was established by Esther C. As shown and described in US Pat. No. 6,591,462 issued to Fuhrman, the disclosure of this patent is incorporated herein by reference.

  The release of the fastener that opens the first and second body portions 106 and 108 is also performed by opening the safety device 128 against the magnetic attraction holding the safety device 128 in the locked position. The first and second main body portions can be performed simply by rotating to the release position, and then the first and second main body portions 106 and 108 are separated in opposite directions to lose the magnetic attractive force. 106 and 108 are easily separated.

  It will be readily apparent to those skilled in the art that various modifications and changes can be made to the jewelry fasteners and their coupling methods of the present invention to obtain improved methods and fasteners. However, all such modifications and changes are within the scope of the present invention as set forth in the appended claims and are within the spirit of the present invention.
