  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 schematically shows a jewelry box 11 according to an embodiment of the present invention. The jewelry box 11 includes a lower box 12 and an upper box 13 that overlaps the lower box 12 and forms a rectangular parallelepiped together with the lower box 12. The lower box body 12 is affixed to a rigid resin molded body having a bottom plate 14a having a square outline and four side walls 14b rising vertically from four sides of the bottom plate 14a, and an outer surface of the resin molded body. And a pasting paper 15 for decorating. The upper box 13 has a square outline top plate 16a, and a side wall 16b that descends from the four sides of the top plate 16a and that forms the side wall of the jewelry box 11 at the lower end and meets the upper end of the side wall 14b of the lower box body 12. It has a hard resin molded body and an adhesive paper 17 that is attached to the outer surface of the resin molded body and decorates the resin molded body. For example, suede or cloth material may be used for the stickers 15 and 17.

  As shown in FIG. 2, the cushioning material 18 is fitted into the lower box 12 in a rectangular parallelepiped space surrounded by the side wall 14 b. The buffer material 18 is formed of, for example, a sponge and a cloth material 18a that wraps the sponge. A slit 19 is formed in the buffer material 18. For example, a ring 21 is inserted into the slit 19. The ring 21 is held in the slit 19 by the elastic force of the cushioning material 18.

  The ring 21 includes, for example, a platinum ring member 22 having a diameter corresponding to the thickness of the finger, and diamond grains 23 fixed to the base of the ring member 22. There may be one or more diamond grains 23. The diamond grains 23 have a blue fluorescence (strong blue or berry strong blue) that is greater than or equal to strong. The diamond grain 23 shines transparent under visible light (for example, natural light or light of electric light), while shining blue under ultraviolet light. Thus, the diamond particles 23 are supported by the lower box 12.

  A lining material 24 is fitted into the upper box 13 in a rectangular parallelepiped space surrounded by the side wall 16b. The lining material 24 includes a rectangular outline decorative top plate 24a that forms the ceiling surface of the jewelry box 11, and four inner layers that are stacked on the four side walls 16b continuously from the four sides of the decorative top plate 24a. A tension plate 24b. Here, the four lining plates 24b are not bonded to the inner surface of the side wall 16b, and the lining material 24 is detachably accommodated in the upper box body 13.

  As shown in FIG. 3, the upper box 13 is connected to the lower box 12 by a hinge 26 so as to be freely opened and closed. The hinge 26 is overlapped and fixed to the one side wall 16b of the upper box body 13 from the inside, and is fixed to the first blade 27 having a plurality of tube bodies 27a and the side wall 14b of the lower box body 12 from the inside. The second blade 28 having a plurality of tube bodies 28a alternately arranged in series on the tube body 27a of the first blade 27, and the tube body 27a of the first blade 27 27 and the tube body 28a of the second blade 28 are inserted in common. The hinge pin 29 is provided. The first blade 27 and the second blade 28 rotate relatively around the hinge pin 29.

  A leaf spring 31 is connected to the hinge 26. As shown in FIG. 4, the leaf spring 31 is formed in a curved body that maintains a generatrix parallel to the axial center of the hinge pin 29. Both ends of the leaf spring 31 are coupled to the first blade 27 and the second blade 28 at positions away from the hinge pin 29, respectively. In the closed position where the lower end of the upper box body 13 is aligned with the upper end of the lower box body 12, the first blade 27 and the second blade 28 are arranged side by side along one surface, and the intermediate region of the leaf spring 31 extends from the hinge pin 29. Move farthest inward. As the upper box 13 is displaced from the closed position to the open position around the hinge pin 29, the outer angle between the first blade 27 and the second blade 28 narrows, and the intermediate region of the leaf spring 31 approaches the hinge pin 29. To do. As shown in FIG. 5, when the intermediate region of the leaf spring 31 contacts the hinge pin 29, the displacement of the upper box body 13 around the hinge pin 29 relative to the lower box body 12 is restricted, and the opening position of the upper box body 13 is It is prescribed. When the opening is smaller than the prescribed intermediate opening around the hinge pin 29, the leaf spring 31 applies a driving force to the upper box 13 toward the closed position. If the opening is larger than the prescribed intermediate opening, the leaf spring 31 applies a driving force to the upper box 13 toward the open position. The hinge 26 and the leaf spring 31 are covered with a hinge cover 32. The hinge cover 32 is formed of a material equivalent to the cloth material 18a of the cushioning material 18, for example.

  An LED lamp (light source) 33 that emits ultraviolet rays in accordance with a predetermined directivity Dv is embedded in the decorative top plate 24a of the upper box 13. The LED lamp 33 emits light having a long wavelength UV-A (wavelength of 315 nm to 400 nm), for example. Desirably, the LED lamp 33 emits only light rays other than visible light rays. Desirably, the LED lamp 33 has a narrow directivity Dv. The LED lamp 33 has directivity Dv that is blocked by the lower box over the entire irradiation area.

  Connected to the LED lamp 33 is a battery 35 housed in a battery chamber 34 defined between a top plate 16a and a decorative top plate 24a. For example, a thin button battery may be used as the battery 35. Here, for example, a plurality of button batteries are connected in series. A current is supplied from the battery 35 to the LED lamp 33.

  The hinge 26 and the leaf spring 31 incorporate a switch 36 that controls supply and disconnection of current to the LED lamp 33. A first contact 37 is fixed to an intermediate region of the leaf spring 31 while being electrically insulated from the leaf spring 31. The hinge 26 functions as a second contact constituting the switch 36 in cooperation with the first contact 37. Therefore, the hinge 26 is formed from a conductive material. The first contact 37 is made of a conductive material such as copper. For example, an insulator is sandwiched between the first contact 37 and the leaf spring 31. The first contact point 37 is disposed on the surface of the leaf spring 31 that faces the hinge pin 29. The first contact 37 contacts the hinge 26 at the open position of the upper box 13 and is separated from the hinge 26 at other positions.

  As shown in FIG. 6, in the jewelry box 11, the electronic circuit 38 according to the first specific example including the LED lamp 33, the battery 35, and the switch 36 is constructed. In the electronic circuit 38, the LED element of the LED lamp 33 is connected in series with the battery 35. The LED lamp 33 is connected in series with a switch 36 and a timer-limited normally closed contact (hereinafter “normally closed contact”) 39. A timer 41 is connected in parallel to the LED lamp 33 and the normally closed contact 39. When the switch 36 is turned on, the LED lamp 33 is energized and lit. A timer 41 is activated when the switch 36 is turned on, and the normally closed contact 39 is opened after a predetermined time has elapsed. As a result, the LED lamp 33 is turned off. When the switch 36 is opened, the timer 41 is restored and the LED lamp 33 is turned off.

  In the electronic circuit 38, the LED lamp 33, the normally closed contact 39, and the timer 41 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  Next, the operation of the jewelry box 11 will be described. As shown in FIG. 1, when the upper box 13 is located at the closed position, the lower edge of the upper box 13 is aligned with the upper edge of the lower box 12. The upper box 13 covers the ring 21 and hides the diamond grains 23. An observer of the jewelry box 11 visually recognizes the appearance of the closed jewelry box 11. The diamond grains 23 are out of view of the observer.

  At this time, as shown in FIG. 4, the intermediate region of the leaf spring 31 is furthest away from the hinge pin 29. Accordingly, the first contact 37 of the switch 36 is separated from the hinge 26, that is, the second contact. The switch 36 of the electronic circuit 38 is disconnected.

  When the observer moves the upper box 12 toward the opening position around the hinge pin 29 against the elastic force of the leaf spring 31, the lower end of the upper box 13 moves away from the upper end of the lower box 12. Visible light (natural light or light of electric light) is inserted from the gap between the upper box 13 and the lower box 12 toward the diamond grains 23. The diamond grains 23 are gradually exposed. Diamond grains 23 are exposed to visible light irradiation. Therefore, the diamond grain 23 emits a transparent shine.

  When the opening degree of the upper box body 13 increases beyond the prescribed intermediate opening degree, the leaf spring 31 drives the upper box body 13 toward the open position. As a result, the upper box 13 reaches the open position with the maximum opening. The upper box 13 is held in the open position according to the elastic force of the leaf spring 31. As shown in FIG. 2, the observer can visually recognize the diamond grains 23 without being blocked by the upper box 13.

  When the upper box 13 reaches the open position, the intermediate region of the leaf spring 31 is pressed against the hinge 29 by receiving the elastic force of the leaf spring 31 as shown in FIG. Thus, the first contact 37 contacts the hinge 26, that is, the second contact. The switch 36 of the electronic circuit 38 becomes conductive. The LED lamp 33 is lit. The LED lamp 33 irradiates the diamond grains 23 with ultraviolet rays. Diamond grains 23 shine blue.

  Thus, when the upper box 13 is released from the closed position, the diamond particles 23 shining blue enter the observer's field of view. In general, the diamond grains 23 of blue fluorescence that are not familiar to the viewer cause a surprising feeling to the observer. When the ring 21 is taken out from the jewelry box 11, the diamond grains 23 emit a transparent shine under visible light (natural light or electric light). In this way, ultraviolet rays and visible light are sequentially irradiated to produce a light effect such as discoloration of the diamond grains 23. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11.

  In the electronic circuit 38, the timer 41 operates according to the conduction of the switch 36. When the upper box 13 reaches the open position and a predetermined time elapses, the normally closed contact 39 is opened. As a result, the LED lamp 33 is turned off. After the upper box 13 is opened, the diamond particles 23 shining blue are observed for a while, and then the diamond particles 23 change from blue to transparent. When the upper lid 13 is closed from the open position and the switch 36 is disconnected, the LED lamp 33 is turned off.

  Here, the LED lamp 33 emits light other than visible light. Since the light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, only the blue fluorescence of the diamond grains 23 emerges, and the production effect can be further enhanced.

  The LED lamp 33 has directivity Dv that is blocked by the lower box 12 over the entire irradiation area. Since the ultraviolet rays do not leak to the outside of the jewelry box 11 other than the light beam that has changed to blue visible light by the fluorescence of the diamond grains 23, the observer of the jewelry box 11 does not have to be exposed to the influence of the ultraviolet rays.

  In the electronic circuit 38, a normally closed momentary switch (tact switch) may be used instead of the switch 36 described above. The momentary switch opens the contact when the upper box 13 overlaps the lower box 12 at the closed position. As soon as the upper box 13 moves away from the closed position, the LED lamp 33 is turned on according to the stroke of the momentary switch. Simultaneously with the opening of the upper box 13, the diamond particles 23 that shine blue enter the field of view of the observer. In general, the diamond grains 23 of blue fluorescence that are not familiar to the viewer cause a surprising feeling to the observer. When the diamond particle 23 is taken out from the jewelry box 11, the diamond particle 23 emits a transparent shine under visible light (natural light or electric light). In this way, ultraviolet rays and visible light are sequentially irradiated to produce a light effect such as discoloration of the diamond grains 23. This stunning effect can cause unparalleled excitement to the observer of the jewelry box.

  FIG. 7 schematically shows a configuration of an electronic circuit 43 according to the second specific example. In the electronic circuit 43, the LED element of the LED lamp 33 is connected in series with the battery 35. A timer-limited normally open contact (hereinafter “normally open contact”) 44 is connected to the LED lamp 33 in series. A switch 36 and a timer 45 are connected in parallel to the LED lamp 33 and the normally open contact 44. When the switch 36 is turned on, the timer 45 is operated, and the normally open contact 44 is closed after a predetermined time has elapsed. As a result, the LED lamp 33 is energized. When the switch 36 is opened, the timer 45 is reset and the normally open contact 44 is opened. As a result, the LED lamp 33 is turned off.

  In the electronic circuit 43, the LED lamp 33, the normally open contact 44 and the timer 45 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  When the upper box 13 reaches the open position, the switch 36 of the electronic circuit 43 is turned on, but the LED lamp 33 is not lit until a predetermined time elapses. Therefore, for a while, as shown in FIG. 2, the observer can visually recognize the diamond grains 23 that emit a transparent shine without being blocked by the upper box 13. When a predetermined time elapses after the switch 36 is turned on (ON operation), the LED lamp 33 is turned on. The LED lamp 33 irradiates the diamond grains 23 with ultraviolet rays. Accordingly, the diamond grains 23 shine blue. Thus, after the upper box 13 is opened, the diamond grains 23 that are shining transparently are observed, and then the diamond grains 23 change from transparent to blue. A light effect is produced according to the opening operation of the upper box 13. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11. When the switch 36 is disconnected, the LED lamp 33 is turned off.

  Here, the LED lamp 33 emits light other than visible light. Since the light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, only the blue fluorescence of the diamond grains 23 emerges, and the production effect can be further enhanced.

  The LED lamp 33 has directivity Dv that is blocked by the lower box 12 over the entire irradiation area. Since the ultraviolet rays do not leak to the outside of the jewelry box 11 other than the light beam that has changed to blue visible light by the fluorescence of the diamond grains 23, the observer of the jewelry box 11 does not have to be exposed to the influence of the ultraviolet rays.

  FIG. 8 schematically shows a configuration of an electronic circuit 47 according to the third specific example. The electronic circuit 47 includes an NPN transistor TR1 connected to the battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R1 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C1 and a second resistor R2 are connected in series between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. The third resistor R3 is connected in parallel with the first resistor R1, the capacitor C1, and the second resistor R2. A fourth resistor R4 is connected between the emitter E of the NPN transistor TR1 and the negative terminal of the battery 35. In the electronic circuit 47, when the switch 36 is energized, a voltage exceeding the threshold is applied to the base B of the NPN transistor TR1 by the action of the second resistor R2. Therefore, current flows instantaneously into the collector C of the NPN transistor TR1. The voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R1 and C1. When the specified time has elapsed, the voltage applied to the base B of the NPN transistor TR1 is kept constant. When the switch 36 is disconnected, the charge of the capacitor C1 is discharged through the third resistor R3.

  In the electronic circuit 47, the LED lamp 33, the NPN transistor TR1, the capacitor C1, and the first to fourth resistors R1 to R4 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  When the upper box 13 reaches the open position, the switch 36 of the electronic circuit 38 becomes conductive. In response to the conduction (ON operation) of the switch 36, a voltage is applied from the battery 35 to the base B of the NPN transistor TR1 in the electronic circuit 38. Current flows into the base B of the NPN transistor TR1, and the LED lamp 33 starts to light.

  The voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R1 and C1. The amount of current flowing through the LED lamp 33 gradually increases. The amount of ultraviolet light applied to the diamond grains 23 from the LED lamp 33 increases. The diamond grains 23 gradually change from transparent to blue. Thus, a light effect is created according to the opening operation of the upper box 13. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11. When the switch 36 is disconnected, the charge of the capacitor C1 is discharged through the third resistor R3.

  Here, the LED lamp 33 emits light other than visible light. Since the light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, only the blue fluorescence of the diamond grains 23 emerges, and the production effect can be further enhanced.

  The LED lamp 33 has directivity Dv that is blocked by the lower box 12 over the entire irradiation area. Since the ultraviolet rays do not leak to the outside of the jewelry box 11 other than the light beam that has changed to blue visible light by the fluorescence of the diamond grains 23, the observer of the jewelry box 11 does not have to be exposed to the influence of the ultraviolet rays.

  FIG. 9 schematically shows a configuration of an electronic circuit 48 according to a fourth specific example. The electronic circuit 48 includes an NPN transistor TR1 connected to the battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R5 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C2 is connected between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. The second resistor R6 is connected in parallel with the first resistor R5 and the capacitor C2. The emitter E of the NPN transistor TR1 is connected to the negative terminal of the battery 35. In the electronic circuit 48, when the switch 36 is turned on, the voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R5 and C2. When the voltage reaches the threshold value at the base B of the NPN transistor TR1, current flows into the collector C. Thereafter, when a predetermined time elapses, the voltage applied to the base B of the NPN transistor TR1 is kept constant. When the switch 36 is disconnected, the charge of the capacitor C2 is discharged through the second resistor R6.

  In the electronic circuit 48, the LED lamp 33, the NPN transistor TR1, the capacitor C2, and the first and second resistors R5 and R6 may be mounted on a common printed board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  In the electronic circuit 48 according to the fourth specific example, after the upper box 13 reaches the open position and the switch 36 is turned on, after the switch 36 is turned on (on operation), a predetermined time elapses. A specified voltage is applied from the battery 35 to the base B of the NPN transistor TR1. Current flows into the collector C of the NPN transistor TR1, and the LED lamp 33 starts to light. Therefore, the observer of the jewelry box 11 can observe the diamond particles 23 that are shining transparently for a while after the upper box 13 is opened.

  The voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R5 and C2. The amount of current flowing through the LED lamp 33 gradually increases. The amount of ultraviolet light applied to the diamond grains 23 from the LED lamp 33 increases. The diamond grains 23 gradually change from transparent to blue. Thus, a light effect is created according to the opening operation of the upper box 13. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11. When the switch 36 is disconnected, the charge of the capacitor C2 is discharged through the second resistor R6.

  The LED lamp 33 may be supported by the lower box 12 instead of the upper box 13, and in this case, the LED lamp 33 has a directivity Dv that is blocked by the upper box 13 over the entire irradiation area. do it. In addition, the diamond grains 23 may be mounted on a plurality of pedestals forming a chain of necklaces. The pedestal is formed from a metal material such as platinum or gold. One diamond grain 23 may be fixed to each pedestal, or a plurality of diamond grains 23 may be fixed. In addition, the diamond grain 23 may be applied on a pendant, a bracelet, a pierced earring, a ring, or an anklet. The diamond grains may be of uniform size or mixed in size.

  In the jewelry box 11 described above, a tact switch having a plunger that is pushed down by the upper box 13 when the upper box 13 reaches the open position may be used as the switch 36. The electronic circuit 38 according to the first specific example and the electronic circuit 43 according to the second specific example may be replaced with electronic circuits having other configurations as long as the same function as described above is realized. Further, as described above, the operation of the switch 36 may be interlocked with the upper box body 13 positioned at the open position or may be interlocked with the upper box body 13 positioned at the closed position. In addition, the functions of the electronic circuits 38, 43, 47, and 48 may be realized by software executed by a microprocessor (MPU).

According to the first aspect of the present invention, a lower box body, a cushioning material fitted into the lower box body and having a cloth material on the surface, and supported by the lower box body on the cloth material , blue fluorescent light The upper box body which is connected to the lower box body by a hinge so as to be freely opened and closed, is concealed with the lower box body in the closed position and conceals the diamond in the open position, and the lower box body is exposed to the lower box body. A jewelry box is provided that is supported by a box or the upper box and that has a light source that emits a transparent light beam including ultraviolet rays toward the diamond when the upper box is opened from the closed position. .

According to the 2nd side, in addition to the composition of the 1st side, the light source has directivity intercepted by the lower box and the upper box in the whole irradiation field.

According to the first aspect, when the upper box is opened from the closed position, ultraviolet rays are irradiated toward the diamond. Diamonds shine blue. The blue shining diamond enters the observer's field of view. In general, diamonds with blue fluorescence that are unfamiliar cause an emotional surprise to the viewer. At this time, since a transparent light beam is irradiated from the light source toward the diamond, a blue spot is not generated on the cloth material. Since the light emitted from the light source is not visible to the observer of the diamond, only the blue fluorescence of the diamond emerges, which can cause the viewer to feel like no other.

According to the second aspect, since the ultraviolet light does not leak outside the jewelry box except for the light beam that has changed to blue visible light due to the fluorescence of the diamond, the observer of the jewelry box need not be exposed to the influence of the ultraviolet light.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 schematically shows a jewelry box 11 according to an embodiment of the present invention. The jewelry box 11 includes a lower box 12 and an upper box 13 that overlaps the lower box 12 and forms a rectangular parallelepiped together with the lower box 12. The lower box body 12 is affixed to a rigid resin molded body having a bottom plate 14a having a square outline and four side walls 14b rising vertically from four sides of the bottom plate 14a, and an outer surface of the resin molded body. And a pasting paper 15 for decorating. The upper box 13 has a square outline top plate 16a, and a side wall 16b that descends from the four sides of the top plate 16a and that forms the side wall of the jewelry box 11 at the lower end and meets the upper end of the side wall 14b of the lower box body 12. It has a hard resin molded body and an adhesive paper 17 that is attached to the outer surface of the resin molded body and decorates the resin molded body. For example, suede or cloth material may be used for the stickers 15 and 17.

  As shown in FIG. 2, the cushioning material 18 is fitted into the lower box 12 in a rectangular parallelepiped space surrounded by the side wall 14 b. The buffer material 18 is formed of, for example, a sponge and a cloth material 18a that wraps the sponge. A slit 19 is formed in the buffer material 18. For example, a ring 21 is inserted into the slit 19. The ring 21 is held in the slit 19 by the elastic force of the cushioning material 18.

  The ring 21 includes, for example, a platinum ring member 22 having a diameter corresponding to the thickness of the finger, and diamond grains 23 fixed to the base of the ring member 22. There may be one or more diamond grains 23. The diamond grains 23 have a blue fluorescence (strong blue or berry strong blue) that is greater than or equal to strong. The diamond grain 23 shines transparent under visible light (for example, natural light or light of electric light), while shining blue under ultraviolet light. Thus, the diamond particles 23 are supported by the lower box 12.

  A lining material 24 is fitted into the upper box 13 in a rectangular parallelepiped space surrounded by the side wall 16b. The lining material 24 includes a rectangular outline decorative top plate 24a that forms the ceiling surface of the jewelry box 11, and four inner layers that are stacked on the four side walls 16b continuously from the four sides of the decorative top plate 24a. A tension plate 24b. Here, the four lining plates 24b are not bonded to the inner surface of the side wall 16b, and the lining material 24 is detachably accommodated in the upper box body 13.

  As shown in FIG. 3, the upper box 13 is connected to the lower box 12 by a hinge 26 so as to be freely opened and closed. The hinge 26 is overlapped and fixed to the one side wall 16b of the upper box body 13 from the inside, and is fixed to the first blade 27 having a plurality of tube bodies 27a and the side wall 14b of the lower box body 12 from the inside. The second blade 28 having a plurality of tube bodies 28a alternately arranged in series on the tube body 27a of the first blade 27, and the tube body 27a of the first blade 27 27 and the tube body 28a of the second blade 28 are inserted in common. The hinge pin 29 is provided. The first blade 27 and the second blade 28 rotate relatively around the hinge pin 29.

  A leaf spring 31 is connected to the hinge 26. As shown in FIG. 4, the leaf spring 31 is formed in a curved body that maintains a generatrix parallel to the axial center of the hinge pin 29. Both ends of the leaf spring 31 are coupled to the first blade 27 and the second blade 28 at positions away from the hinge pin 29, respectively. In the closed position where the lower end of the upper box body 13 is aligned with the upper end of the lower box body 12, the first blade 27 and the second blade 28 are arranged side by side along one surface, and the intermediate region of the leaf spring 31 extends from the hinge pin 29. Move farthest inward. As the upper box 13 is displaced from the closed position to the open position around the hinge pin 29, the outer angle between the first blade 27 and the second blade 28 narrows, and the intermediate region of the leaf spring 31 approaches the hinge pin 29. To do. As shown in FIG. 5, when the intermediate region of the leaf spring 31 contacts the hinge pin 29, the displacement of the upper box body 13 around the hinge pin 29 relative to the lower box body 12 is restricted, and the opening position of the upper box body 13 is It is prescribed. When the opening is smaller than the prescribed intermediate opening around the hinge pin 29, the leaf spring 31 applies a driving force to the upper box 13 toward the closed position. If the opening is larger than the prescribed intermediate opening, the leaf spring 31 applies a driving force to the upper box 13 toward the open position. The hinge 26 and the leaf spring 31 are covered with a hinge cover 32. The hinge cover 32 is formed of a material equivalent to the cloth material 18a of the cushioning material 18, for example.

  An LED lamp (light source) 33 that emits ultraviolet rays in accordance with a predetermined directivity Dv is embedded in the decorative top plate 24a of the upper box 13. The LED lamp 33 emits light having a long wavelength UV-A (wavelength of 315 nm to 400 nm), for example. Desirably, the LED lamp 33 emits only light rays other than visible light rays. Desirably, the LED lamp 33 has a narrow directivity Dv. The LED lamp 33 has directivity Dv that is blocked by the lower box over the entire irradiation area.

  Connected to the LED lamp 33 is a battery 35 housed in a battery chamber 34 defined between a top plate 16a and a decorative top plate 24a. For example, a thin button battery may be used as the battery 35. Here, for example, a plurality of button batteries are connected in series. A current is supplied from the battery 35 to the LED lamp 33.

  The hinge 26 and the leaf spring 31 incorporate a switch 36 that controls supply and disconnection of current to the LED lamp 33. A first contact 37 is fixed to an intermediate region of the leaf spring 31 while being electrically insulated from the leaf spring 31. The hinge 26 functions as a second contact constituting the switch 36 in cooperation with the first contact 37. Therefore, the hinge 26 is formed from a conductive material. The first contact 37 is made of a conductive material such as copper. For example, an insulator is sandwiched between the first contact 37 and the leaf spring 31. The first contact point 37 is disposed on the surface of the leaf spring 31 that faces the hinge pin 29. The first contact 37 contacts the hinge 26 at the open position of the upper box 13 and is separated from the hinge 26 at other positions.

  As shown in FIG. 6, in the jewelry box 11, the electronic circuit 38 according to the first specific example including the LED lamp 33, the battery 35, and the switch 36 is constructed. In the electronic circuit 38, the LED element of the LED lamp 33 is connected in series with the battery 35. The LED lamp 33 is connected in series with a switch 36 and a timer-limited normally closed contact (hereinafter “normally closed contact”) 39. A timer 41 is connected in parallel to the LED lamp 33 and the normally closed contact 39. When the switch 36 is turned on, the LED lamp 33 is energized and lit. A timer 41 is activated when the switch 36 is turned on, and the normally closed contact 39 is opened after a predetermined time has elapsed. As a result, the LED lamp 33 is turned off. When the switch 36 is opened, the timer 41 is restored and the LED lamp 33 is turned off.

  In the electronic circuit 38, the LED lamp 33, the normally closed contact 39, and the timer 41 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  Next, the operation of the jewelry box 11 will be described. As shown in FIG. 1, when the upper box 13 is located at the closed position, the lower edge of the upper box 13 is aligned with the upper edge of the lower box 12. The upper box 13 covers the ring 21 and hides the diamond grains 23. An observer of the jewelry box 11 visually recognizes the appearance of the closed jewelry box 11. The diamond grains 23 are out of view of the observer.

  At this time, as shown in FIG. 4, the intermediate region of the leaf spring 31 is furthest away from the hinge pin 29. Accordingly, the first contact 37 of the switch 36 is separated from the hinge 26, that is, the second contact. The switch 36 of the electronic circuit 38 is disconnected.

  When the observer moves the upper box 12 toward the opening position around the hinge pin 29 against the elastic force of the leaf spring 31, the lower end of the upper box 13 moves away from the upper end of the lower box 12. Visible light (natural light or light of electric light) is inserted from the gap between the upper box 13 and the lower box 12 toward the diamond grains 23. The diamond grains 23 are gradually exposed. Diamond grains 23 are exposed to visible light irradiation. Therefore, the diamond grain 23 emits a transparent shine.

  When the opening degree of the upper box body 13 increases beyond the prescribed intermediate opening degree, the leaf spring 31 drives the upper box body 13 toward the open position. As a result, the upper box 13 reaches the open position with the maximum opening. The upper box 13 is held in the open position according to the elastic force of the leaf spring 31. As shown in FIG. 2, the observer can visually recognize the diamond grains 23 without being blocked by the upper box 13.

  When the upper box 13 reaches the open position, the intermediate region of the leaf spring 31 is pressed against the hinge 29 by receiving the elastic force of the leaf spring 31 as shown in FIG. Thus, the first contact 37 contacts the hinge 26, that is, the second contact. The switch 36 of the electronic circuit 38 becomes conductive. The LED lamp 33 is lit. The LED lamp 33 irradiates the diamond grains 23 with ultraviolet rays. Diamond grains 23 shine blue.

  Thus, when the upper box 13 is released from the closed position, the diamond particles 23 shining blue enter the observer's field of view. In general, the diamond grains 23 of blue fluorescence that are not familiar to the viewer cause a surprising feeling to the observer. When the ring 21 is taken out from the jewelry box 11, the diamond grains 23 emit a transparent shine under visible light (natural light or electric light). In this way, ultraviolet rays and visible light are sequentially irradiated to produce a light effect such as discoloration of the diamond grains 23. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11.

  In the electronic circuit 38, the timer 41 operates according to the conduction of the switch 36. When the upper box 13 reaches the open position and a predetermined time elapses, the normally closed contact 39 is opened. As a result, the LED lamp 33 is turned off. After the upper box 13 is opened, the diamond particles 23 shining blue are observed for a while, and then the diamond particles 23 change from blue to transparent. When the upper lid 13 is closed from the open position and the switch 36 is disconnected, the LED lamp 33 is turned off.

  Here, the LED lamp 33 emits light other than visible light. Since the light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, only the blue fluorescence of the diamond grains 23 emerges, and the production effect can be further enhanced.

  The LED lamp 33 has directivity Dv that is blocked by the lower box 12 over the entire irradiation area. Since the ultraviolet rays do not leak to the outside of the jewelry box 11 other than the light beam that has changed to blue visible light by the fluorescence of the diamond grains 23, the observer of the jewelry box 11 does not have to be exposed to the influence of the ultraviolet rays.

  In the electronic circuit 38, a normally closed momentary switch (tact switch) may be used instead of the switch 36 described above. The momentary switch opens the contact when the upper box 13 overlaps the lower box 12 at the closed position. As soon as the upper box 13 moves away from the closed position, the LED lamp 33 is turned on according to the stroke of the momentary switch. Simultaneously with the opening of the upper box 13, the diamond particles 23 that shine blue enter the field of view of the observer. In general, the diamond grains 23 of blue fluorescence that are not familiar to the viewer cause a surprising feeling to the observer. When the diamond particle 23 is taken out from the jewelry box 11, the diamond particle 23 emits a transparent shine under visible light (natural light or electric light). In this way, ultraviolet rays and visible light are sequentially irradiated to produce a light effect such as discoloration of the diamond grains 23. This stunning effect can cause unparalleled excitement to the observer of the jewelry box.

  FIG. 7 schematically shows a configuration of an electronic circuit 43 according to the second specific example. In the electronic circuit 43, the LED element of the LED lamp 33 is connected in series with the battery 35. A timer-limited normally open contact (hereinafter “normally open contact”) 44 is connected to the LED lamp 33 in series. A switch 36 and a timer 45 are connected in parallel to the LED lamp 33 and the normally open contact 44. When the switch 36 is turned on, the timer 45 is operated, and the normally open contact 44 is closed after a predetermined time has elapsed. As a result, the LED lamp 33 is energized. When the switch 36 is opened, the timer 45 is reset and the normally open contact 44 is opened. As a result, the LED lamp 33 is turned off.

  In the electronic circuit 43, the LED lamp 33, the normally open contact 44 and the timer 45 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  When the upper box 13 reaches the open position, the switch 36 of the electronic circuit 43 is turned on, but the LED lamp 33 is not lit until a predetermined time elapses. Therefore, for a while, as shown in FIG. 2, the observer can visually recognize the diamond grains 23 that emit a transparent shine without being blocked by the upper box 13. When a predetermined time elapses after the switch 36 is turned on (ON operation), the LED lamp 33 is turned on. The LED lamp 33 irradiates the diamond grains 23 with ultraviolet rays. Accordingly, the diamond grains 23 shine blue. Thus, after the upper box 13 is opened, the diamond grains 23 that are shining transparently are observed, and then the diamond grains 23 change from transparent to blue. A light effect is produced according to the opening operation of the upper box 13. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11. When the switch 36 is disconnected, the LED lamp 33 is turned off.

  Here, the LED lamp 33 emits light other than visible light. Since the light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, only the blue fluorescence of the diamond grains 23 emerges, and the production effect can be further enhanced.

  The LED lamp 33 has directivity Dv that is blocked by the lower box 12 over the entire irradiation area. Since the ultraviolet rays do not leak to the outside of the jewelry box 11 other than the light beam that has changed to blue visible light by the fluorescence of the diamond grains 23, the observer of the jewelry box 11 does not have to be exposed to the influence of the ultraviolet rays.

  FIG. 8 schematically shows a configuration of an electronic circuit 47 according to the third specific example. The electronic circuit 47 includes an NPN transistor TR1 connected to the battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R1 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C1 and a second resistor R2 are connected in series between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. The third resistor R3 is connected in parallel with the first resistor R1, the capacitor C1, and the second resistor R2. A fourth resistor R4 is connected between the emitter E of the NPN transistor TR1 and the negative terminal of the battery 35. In the electronic circuit 47, when the switch 36 is energized, a voltage exceeding the threshold is applied to the base B of the NPN transistor TR1 by the action of the second resistor R2. Therefore, current flows instantaneously into the collector C of the NPN transistor TR1. The voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R1 and C1. When the specified time has elapsed, the voltage applied to the base B of the NPN transistor TR1 is kept constant. When the switch 36 is disconnected, the charge of the capacitor C1 is discharged through the third resistor R3.

  In the electronic circuit 47, the LED lamp 33, the NPN transistor TR1, the capacitor C1, and the first to fourth resistors R1 to R4 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  When the upper box 13 reaches the open position, the switch 36 of the electronic circuit 38 becomes conductive. In response to the conduction (ON operation) of the switch 36, a voltage is applied from the battery 35 to the base B of the NPN transistor TR1 in the electronic circuit 38. Current flows into the base B of the NPN transistor TR1, and the LED lamp 33 starts to light.

  The voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R1 and C1. The amount of current flowing through the LED lamp 33 gradually increases. The amount of ultraviolet light applied to the diamond grains 23 from the LED lamp 33 increases. The diamond grains 23 gradually change from transparent to blue. Thus, a light effect is created according to the opening operation of the upper box 13. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11. When the switch 36 is disconnected, the charge of the capacitor C1 is discharged through the third resistor R3.

  Here, the LED lamp 33 emits light other than visible light. Since the light emitted from the LED lamp 33 is not visually recognized by the observer of the diamond grains 23, only the blue fluorescence of the diamond grains 23 emerges, and the production effect can be further enhanced.

  The LED lamp 33 has directivity Dv that is blocked by the lower box 12 over the entire irradiation area. Since the ultraviolet rays do not leak to the outside of the jewelry box 11 other than the light beam that has changed to blue visible light by the fluorescence of the diamond grains 23, the observer of the jewelry box 11 does not have to be exposed to the influence of the ultraviolet rays.

  FIG. 9 schematically shows the configuration of an electronic circuit 48 according to a fourth specific example. The electronic circuit 48 includes an NPN transistor TR1 connected to the battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R5 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C2 is connected between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. The second resistor R6 is connected in parallel with the first resistor R5 and the capacitor C2. The emitter E of the NPN transistor TR1 is connected to the negative terminal of the battery 35. In the electronic circuit 48, when the switch 36 is turned on, the voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R5 and C2. When the voltage reaches the threshold value at the base B of the NPN transistor TR1, a current flows into the collector C. Thereafter, when a predetermined time elapses, the voltage applied to the base B of the NPN transistor TR1 is kept constant. When the switch 36 is disconnected, the charge of the capacitor C2 is discharged through the second resistor R6.

  In the electronic circuit 48, the LED lamp 33, the NPN transistor TR1, the capacitor C2, and the first and second resistors R5 and R6 may be mounted on a common printed board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, and the like may be electrically connected to the wiring pattern on the printed circuit board by an electric wire such as a vinyl-coated wire. The printed board may be accommodated in the battery chamber 34, for example.

  In the electronic circuit 48 according to the fourth specific example, after the upper box 13 reaches the open position and the switch 36 is turned on, after the switch 36 is turned on (on operation), a predetermined time elapses. A specified voltage is applied from the battery 35 to the base B of the NPN transistor TR1. Current flows into the collector C of the NPN transistor TR1, and the LED lamp 33 starts to light. Therefore, the observer of the jewelry box 11 can observe the diamond particles 23 that are shining transparently for a while after the upper box 13 is opened.

  The voltage applied to the base B of the NPN transistor TR1 gradually increases by the action of the time constant circuits R5 and C2. The amount of current flowing through the LED lamp 33 gradually increases. The amount of ultraviolet light applied to the diamond grains 23 from the LED lamp 33 increases. The diamond grains 23 gradually change from transparent to blue. Thus, a light effect is created according to the opening operation of the upper box 13. This stunning effect can cause unparalleled excitement to the observer of the jewelry box 11. When the switch 36 is disconnected, the charge of the capacitor C2 is discharged through the second resistor R6.

  The LED lamp 33 may be supported by the lower box 12 instead of the upper box 13, and in this case, the LED lamp 33 has a directivity Dv that is blocked by the upper box 13 over the entire irradiation area. do it. In addition, the diamond grains 23 may be mounted on a plurality of pedestals forming a chain of necklaces. The pedestal is formed from a metal material such as platinum or gold. One diamond grain 23 may be fixed to each pedestal, or a plurality of diamond grains 23 may be fixed. In addition, the diamond grain 23 may be applied on a pendant, a bracelet, a pierced earring, a ring, or an anklet. The diamond grains may be of uniform size or mixed in size.

  In the jewelry box 11 described above, a tact switch having a plunger that is pushed down by the upper box 13 when the upper box 13 reaches the open position may be used as the switch 36. The electronic circuit 38 according to the first specific example and the electronic circuit 43 according to the second specific example may be replaced with electronic circuits having other configurations as long as the same function as described above is realized. Further, as described above, the operation of the switch 36 may be interlocked with the upper box body 13 positioned at the open position or may be interlocked with the upper box body 13 positioned at the closed position. In addition, the functions of the electronic circuits 38, 43, 47, and 48 may be realized by software executed by a microprocessor (MPU).
