BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging stand that is set so that a portable game device can be attached and detached and charges a battery pack of the game device, and in particular, a game device equipped with a battery pack in place of a dry battery The present invention relates to a charging stand for charging a battery.
[0002]
[Prior art]
A game machine can be used economically by repeatedly charging and discharging a battery pack using a battery pack instead of a dry battery. Since game machines have a long use time and a large amount of use, there is a feature that the amount of dry batteries discarded nationwide can be remarkably reduced by replacing the dry batteries with pack batteries. A battery pack that can be used in place of a dry battery is described in Japanese Utility Model Publication No. 6-44011. The battery pack described in this publication has two cylindrical batteries 15 arranged in parallel and connected by a holder 4 as shown in FIG.
[0003]
In the battery pack of this figure, the electrode terminal of the secondary battery is brought into contact with the contact of the dry cell storage unit. The battery pack having this structure can be charged by connecting a charger to the game machine. The charger can charge the battery pack while supplying power to the game device. However, the game machine connected to the charger via the lead wire cannot be used conveniently. This is because it takes time to connect the lead wire when supplying power to the game device or charging the battery pack, and to remove the lead wire when using the battery pack.
[0004]
This disadvantage can be solved by a structure in which a charging terminal is provided at the lower end of the case and a contact point of the charger is disposed at a position where the charging terminal contacts, as in a mobile phone. In the charger having this structure, when the game device is set on the mounting portion, power is supplied from the charger and the battery pack is charged. The game device can be attached and detached very easily by setting the mounting portion of the charger as a concave portion opened upward. For this reason, when supplying electric power from a battery pack without using a charger, it can be conveniently removed from the charger mounting portion.
[0005]
[Problems to be solved by the invention]
However, a structure in which a charging terminal is provided at the lower end of the game device and an output contact that contacts the charging terminal is provided at the bottom of the mounting portion cannot be used for a game device designed exclusively for dry batteries. This is because game devices designed exclusively for dry batteries do not have a built-in structure for charging the built-in battery.
[0006]
In order to eliminate this drawback, the present applicant has developed a battery pack 29 and a charging stand 30 having the structure shown in FIG. The battery pack 29 has a charging terminal on the back. When the dry battery is replaced with the battery pack 29, the dry battery cover is also replaced with the charging cover 31. The charging lid 31 is provided with a through hole 35 for exposing the charging terminal of the battery pack 29 to the outside. When the game apparatus 1 is set on the mounting portion 37 of the charging stand 30, the output contact 32 of the charging stand 30 passes through the through hole 35 of the charging lid 31 and contacts the charging terminal of the battery pack 29. In this state, the battery pack 29 attached to the game machine 1 is charged.
[0007]
The structure shown in FIG. 2 can charge the battery pack with fewer contact failures. In addition, a battery pack can be attached to a game machine designed exclusively for dry batteries and used conveniently. Furthermore, as shown in the figure, the battery pack can be charged while using the game device by attaching the game device to the charging stand in an inclined posture.
[0008]
However, in the game device having this structure, when the battery pack is used, the battery lid is removed from the game device and the charging lid is used. When the battery is used, the charging lid is detached from the game device and the battery lid is used. Therefore, either the dry battery lid or the charging lid is not used. For this reason, it takes time to store and store the dry battery lid and the charging lid that are not used, and there is a drawback that they are lost or damaged due to poor storage.
[0009]
The present invention has been developed for the purpose of further solving this drawback, and an important object of the present invention is to use a dry cell lid removed from the game device together with a part of the stand case of the charging stand, It is an object of the present invention to provide a charging stand for a portable game device that can be conveniently stored without losing a dry battery lid that is not used.
[0010]

The locking hook 48 is elastically deformed when the dry cell lid 46 and the charging lid 31 are attached to the dry cell storage unit 2. When the battery pack 2 is mounted at a fixed position, as shown in FIG. 3, the lower edge of the battery pack 2 is inserted into the locking irregularities 48 </ b> A of the locking hook 48. In this state, the dry battery lid 46 and the charging lid 31 are mounted in a state where they are not removed from the dry cell storage unit 2.
[0019]
The dry cell storage unit 2 shown in FIG. 5 mounts two AA type dry cells 16 in the + -reverse direction. The dry cell storage unit 2 is provided with elastic protruding contacts 6 so as to be positioned on diagonal lines at both ends. The elastic protruding contact 6 is formed by winding an elastic wire in a coil shape, and is elastically pressed against and electrically contacted with the negative electrode terminal 5 of the dry battery 16. Although not shown, the elastic protruding contact may be of a shape that elastically protrudes the elastic metal plate toward the dry battery. In the dry cell storage unit 2, an inelastic contact 7 that is in contact with the positive electrode terminal 5 of the dry cell 16 is fixed next to the elastic protruding contact 6. The inelastic contact 7 is also disposed on the diagonal line of the dry cell storage unit 2. The inelastic contact 7 is a metal plate fixed to the inner surface of the dry cell storage unit 2 and is in contact with the positive electrode terminal 5 of the dry cell 16. The elastic protruding contact 6 protrudes from the non-elastic contact 7 and is provided in the dry cell storage unit 2.
[0020]
In the dry cell storage unit 2 of FIG. 5, an elastic protruding contact 6 and an inelastic contact 7 provided on the right side are connected by a lead wire 8. This is because the dry batteries 16 mounted adjacent to the dry battery storage unit 2 are connected in series. In the figure, an elastic protruding contact 6 and an inelastic contact 7 arranged on the left side of the dry cell storage unit 2 serve as a power supply terminal of the game device 1 and supply power to the game device 1.
[0021]
The charging stand 30 of FIGS. 3 and 4 is provided with a mounting portion 37 in the stand case 36 for setting the game machine 1 so that it can be attached and detached. The stand case 36 is also provided with an attachment / detachment opening 49 for setting the dry battery lid 46 removed from the game device 1. The charging stand 30 in FIGS. 3 and 10 is provided with a detachable opening 49 in a part of the stand case 36 that closes the connector chamber 50. By attaching the dry battery lid 46 removed from the game device 1 to the attachment / detachment opening 49, the dry battery lid 46 is used together with a part of the stand case 36. The connector chamber 50 is a chamber containing a connector 51 connected to a power cord. In order to pull out the power cord connected to the connector 51 in a state where the dry battery lid 46 closes the detachable opening 49 of the connector chamber 50, a cutout 52 for pulling out the power cord is provided on the side edge of the detachable opening 49. Is provided.
[0022]
As shown in this figure, the charging stand 30 provided with the connector 51 in the connector chamber 50 of the stand case 36 can reduce the contact failure of the connector 51. This is because the connector 51 protects the connector 51 from dirt and further prevents the power cord from coming off. Further, there is also a feature that the power cord connector 51 can be easily attached / detached by removing the dry cell lid 46 of the attaching / detaching opening 49.
[0023]
In the illustrated charging stand 30, a connector chamber 50 is provided on the back, and a detachable opening 49 is provided on the back surface of the connector chamber 50. The attachment / detachment opening 49 preferably has the same shape as the opening of the dry cell storage unit 2. This is because the dry cell lid 46 is removed from the dry cell storage unit 2 and attached to the attachment / detachment opening 49. However, the attachment / detachment opening does not necessarily have to be exactly the same as the shape of the opening of the dry cell storage unit. The attachment / detachment opening may be any shape that can be closed by attaching a dry cell lid and can be attached / detached.
[0024]
The detachable opening 49 can be used more conveniently by allowing both the dry battery lid 46 and the charging lid 31 to be detachable. This is because when the dry battery 16 is set in the game machine 1 and the charging lid 31 is removed, the charging lid 31 can be attached to the attachment / detachment opening 49. In order to realize this, the charging lid 31 and the dry battery lid 46 have the same shape, or the attachment / detachment opening 49 has a structure in which both the dry battery lid 46 and the charging lid 31 having different shapes can be mounted.
[0025]
The charging stand 30 shown in the figure has a structure in which the game device 1 can be set and used. For this reason, the mounting portion 37 has a concave portion that is open upward, and the game device 1 is positioned 30 to 50 degrees backward, preferably 35 to 50 degrees, optimally about 45 degrees with respect to a vertical plane. An inclination holding surface 38 that holds the posture inclined at an angle of is provided at a position facing the back surface of the game machine 1. The game device 1 is set on the mounting portion 37 with the back surface of the game device 1 in contact with the inclined holding surface 38. The tilt angle of the tilt holding surface 38 can be set to the aforementioned angle so that the operation push button 33 can be conveniently pressed with the game apparatus 1 mounted on the charging stand 30 and the monitor of the game apparatus 1 is easy to see. Is done.
[0026]
The mounting portion 37 of the charging stand 30 holds the game device 1 in a playable state that can be tilted somewhat. That is, when the operation push button 33 is pressed, the game device 1 can be slightly moved with respect to the charging stand 30 to move the charging terminal 22 and the output contact 32 of the battery pack 29 relative to each other, thereby reducing contact failure. Because it can. However, if the play that can be tilted is too large, the game device 1 moves each time the operation push button 33 is pressed, so that it cannot be used conveniently. For this reason, the play is such that when the operation push button 33 is pressed, the lower end of the game machine 1 moves, for example, 0.1 to 1.5 mm, preferably 0.2 to 1 mm.
[0027]
In the illustrated charging stand 30, a locking portion 39 that locks the lower end of the front surface of the game device 1 is provided on the surface of the mounting portion 37 that faces the inclined holding surface 38, and the game device 1 is tilted by the locking portion 39. It is locked in a state where there is play that can be done. The mounting portion 37 having this structure has a feature that allows the game machine 1 to be attached and detached very easily.
[0028]
The stand case 36 of the charging stand 30 can be stably placed on a horizontal base in a state where the game device 1 is placed in the mounting portion 37, and the charging stand 30 with the game device 1 attached can be operated with both hands. The push button 33 is operated so that a game can be played. For this reason, the stand case 36 of the charging stand 30 has a length in the front-rear direction of 0.5 to 25 times, preferably 0.8 to 1.5 times the height of the game device 1, and a width of the game device 1. 1.2 to 2.5 times, preferably 1.3 to 2 times.
[0029]
The charging stand 30 protrudes elastically from the inclined holding surface 38 and has an output contact 32 at a position where it contacts the charging terminal 22 of the battery pack 29 attached to the game device 1. The output contact 32 contacts the charging terminal 22 of the battery pack 29. With the output contact 32 in contact with the charging terminal 22, the charging stand 30 charges the battery pack 29. The output contact 32 is an elastically deformable metal wire and is connected to a charging circuit built in the stand case 36.
[0030]
The output contact 32 of FIG. 3 is a bent portion that is bent in a mountain shape at the portion that contacts the charging terminal 22, and is further connected to the rotating shaft 40 so that the right portion of the metal wire can be rotated. When the output contact 32 in this figure is pushed into the charging terminal 22, the bent portion moves along a circular orbit around the rotation shaft 40. The bent portion that moves along the locus moves and is pushed in a direction orthogonal to the tilt holding surface 38 and also moves in the vertical direction that is parallel to the tilt holding surface 38. The bent portion that moves in the vertical direction parallel to the inclined holding surface 38 when being pushed slides with respect to the charging terminal 22 when being pushed by the charging terminal 22. When the bent portion is pushed in, the output contact 32 on which the charging terminal 22 and the bent portion slide can reduce contact failure when the operation push button 33 is pressed. This is because when the operation push button 33 is pressed to push the charging terminal 22 against the output contact 32 and the game apparatus 1 moves relative to the tilt holding surface 38, the charging terminal 22 and the output contact 32 slide. is there.
[0031]
The electric circuit built in the stand case 36 has an output capable of driving the game device 1 while charging the battery pack 29. Therefore, power for driving the game device 1 is supplied while charging the battery pack 29 while the game device 1 to which the battery pack 29 is mounted is set in the mounting portion 37.
[0032]
A battery pack 29 to be mounted in the dry cell storage unit 2 is shown in FIG. The battery pack 29 shown in this figure is electrically connected to the left elastic protruding contact 6 and the non-elastic contact 7 to supply power to the game machine 1. In the battery pack 29 shown in the figure, the right side of the built-in secondary battery 3 is connected by a lead wire 9. The battery pack 29 having this structure is configured to electrically connect the + − electrode terminal 5 on the right side of the secondary battery 3 to the elastic protruding contact 6 and the inelastic contact 7 provided on the right side of the dry cell storage unit 2. In addition, power can be supplied to the game machine 1. Therefore, the battery pack 29 does not need to contact the opposite side of the output terminal 10 to the elastic protruding contact 6 and the non-elastic contact 7 of the dry cell storage unit 2.
[0033]
The battery pack 29 shown in FIGS. 11 to 13 has two secondary batteries 3 connected in parallel by a holder 4 and fixed. The secondary battery 3 is fixed to the holder 4 with the + output terminal 10A protruding from the − output terminal 10B. The secondary battery 3 is a cylindrical rechargeable battery, for example, a nickel-cadmium battery, a nickel-hydrogen battery, a lithium ion secondary battery, or the like. The secondary battery 3 has substantially the same thickness as the dry battery 16 attached to the dry battery storage unit 2 or is slightly thinner. Further, the total length of the secondary battery 3 is slightly shorter than that of the dry battery 16.
[0034]
The battery pack 29 set in the dry cell storage unit 2 designed to be fitted with AA size batteries is substantially the same as or slightly thinner than the AA size batteries, and is slightly shorter than the AA size batteries. A secondary battery 3 is incorporated. The battery pack 29 shown in the figure includes two secondary batteries 3, but the battery pack may include three or more secondary batteries.
[0035]
The total length of the battery pack 29 is the minimum distance between the two elastic protruding contacts 6 arranged to face each other at both ends of the dry cell storage unit 2, that is, the elastic protruding contacts 6 are not compressed. It is longer than the interval between the tip surfaces of the elastic protruding contacts 6 arranged as described above. If the total length of the battery pack 29 is shorter than the minimum distance between the elastic protruding contacts 6, the + − output terminal 10 cannot be electrically connected to the elastic protruding contact 6 and the non-elastic contact 7 which are the power supply terminals of the game machine 1. is there.
[0036]
Further, in the battery pack 29 shown in the figure, two secondary batteries 3 are connected and fixed by the holder 4 in a posture in which the polarity of + − is reversed. As shown by a chain line in FIG. 6, the battery pack 29 is connected in series by connecting the + −electrode terminals 5 of the adjacent secondary batteries 3 with lead wires 9 on the opposite side of the output terminal 10.
[0037]
As shown in FIGS. 11 to 13, the holder 4 includes a metal band 11 and an insulating holder 12. The metal band 11, the insulating holder 12, and the secondary battery 3 are bonded and connected to each other. However, the metal band can be attached in place by elastic deformation without bonding.
[0038]
The metal band 11 is manufactured by processing a metal plate that can be elastically deformed, for example, a stainless steel plate of SUS304, an iron plate having excellent elastic deformation characteristics, or the like. These metal plates have an extremely thin thickness of 0.1 to 0.3 mm, and can be reliably held in a state in which the secondary battery 3 is elastically pressed. The metal band 11 of the stainless steel plate can be made extremely thin with a thickness of 0.2 mm. The metal band 11 holds and connects the secondary battery 3 whose surface is covered with an insulating material such as a heat shrink film.
[0039]
As shown in the cross-sectional view of FIG. 13, the metal band 11 is a groove type in which curved side walls 11B are provided on both sides of the back plate 11A so that the metal plate can hold two secondary batteries 3 in parallel. It is. The back plate 11 </ b> A is planar, and the curved side wall 11 </ b> B is curved along the surface of the cylindrical secondary battery 3. Furthermore, the curved side wall 11 </ b> B has a holding portion 11 a that is curved in the direction of gradually narrowing the opening width toward the opening edge at the tip portion. The metal band 11 of FIG. 13 extends the front end edge of the holding portion 11a to a position where the inclination angle α with respect to the back plate 11A is about 45 degrees. The curved side wall 11B can hold the secondary battery 3 more reliably as the holding portion 11a is extended longer. However, when the holding portion 11a is lengthened, the outer shape of the battery pack 29 is increased. Therefore, the curved side wall 11B is preferably extended to such a length that the inclination angle α of the leading edge of the holding portion 11a is 20 to 80 degrees, preferably 30 to 60 degrees.
[0040]
The insulating holder 12 is formed by molding an insulating material such as plastic, and includes an end cover portion 12A disposed at an end portion of the secondary battery 3 and a connecting portion 12B disposed on the inner surface of the metal band 11. Have. The end cover portion 12A includes an output terminal cover portion 12a on the output terminal 10 side and a bottom cover portion 12b.
[0041]
FIG. 14 is a perspective view showing the portion connecting the metal band 11 and the end cover portion 12A in an easy-to-understand manner. FIG. 15 shows an enlarged cross-sectional view of the main part of this figure. In the battery pack 29 shown in these drawings, the output terminal cover portion 12a, which is one end cover portion 12A, is connected to the metal band 11. The metal band 11 connects the holding portion 11a to the surface of the output end cover portion 12a, which is the end cover portion 12A, with a locking structure.
[0042]
The battery pack 29 in this figure has a locking structure between the holding part 11a of the metal band 11 and the end cover part 12A provided on the locking claw 25 provided on the holding part 11a and the end cover part 12A. The latching recess 26 into which the latching claw 25 is inserted is constituted. The locking claw 25 of the holding part 11a is inserted into the locking recess 26 by the elasticity of the metal band 11, and connects the metal band 11 and the output end cover part 12a. As shown in the sectional view of FIG. 16, the metal band 11 and the end cover portion 12 </ b> A have a locking projection 27 provided on the end cover portion 12 </ b> A, and the locking projection 27 is inserted. A structure in which the hole 28 is provided in the holding portion 11 a of the metal band 11 and the locking projection 27 is inserted into the locking hole 28 can also be adopted. Also in the locking structure of this figure, the metal band 11 is elastically pressed against the surface of the end cover portion 12A, and the locking projection 27 is inserted into the locking hole 28 so that the metal band 11 and the end cover portion 12A are inserted. Are securely connected.
[0043]
The output terminal cover portion 12a shown in FIGS. 17 and 18 has an outer shape that conforms to the outer shape of the cylindrical secondary battery 3, and incorporates a metal cap 18 that is the output terminal 10. The metal cap 18 is elastically pushed out by a spring 19. The output terminal cover part 12a containing the metal cap 18 that is elastically pushed out is deformed by the spring 19 or is easily displaced, but is connected to the holding part 11a of the metal band 11 with a locking structure, Deformation and displacement can be prevented.
[0044]
The battery pack 29 shown in the figure has an output terminal cover portion 12a, which is one end cover portion 12A, connected to the holding portion 11a of the metal band 11. However, the battery pack 29 of the present invention includes an output terminal cover portion and Both bottom cover parts can be connected to the holding part with the same locking structure, or only the bottom cover part can be connected to the metal band with the same locking structure.
[0045]
The bottom cover portion 12b is provided with lead wires 9 on the inner surface for connecting the two secondary batteries 3 in series. Further, the bottom cover portion 12b has a slit, and a guide groove 13 for guiding the elastic protruding contact 6 of the dry cell storage portion 2 is provided by the slit. The guide groove 13 is disposed at a position facing the negative electrode terminal 5 of the built-in secondary battery 3. Since the bottom cover portion 12 b in the figure forms the guide groove 13 with a slit, the surface of the negative electrode terminal 5 of the secondary battery 3 becomes the bottom surface of the guide groove 13. The guide groove 13 constituted by a slit is provided so as to extend from the central portion of the negative electrode terminal 5 of the secondary battery 3 to the bottom surface side of the dry cell storage portion 2. This is because the elastic protruding contact 6 is moved along the guide groove 13 when the battery pack 29 is inserted into the dry cell storage unit 2. The battery pack 29 having the negative electrode terminal surface of the secondary battery 3 as the bottom surface of the guide groove 13 can deepen the guide groove 13.
[0046]
However, the battery pack in which the secondary batteries are connected in series inside the bottom cover portion is connected to the + − electrode terminal of the secondary battery arranged inside the bottom cover portion and the elastic protruding contact of the dry battery storage portion. Since there is no need to make contact with the elastic contact, a bottom guide groove can be formed in the bottom cover portion.
[0047]
The depth of the guide groove 13 is preferably set to such a depth that the elastic protruding contact 6 of the dry cell storage unit 2 does not elastically press the bottom of the guide groove 13 in a state where the battery pack 29 is mounted in the dry cell storage unit 2. The battery pack 29 having this structure can be placed in the dry cell storage unit 2 most easily. This is because the battery pack 29 can be attached to the dry cell storage portion 2 without compressing the elastic protruding contact 6 disposed opposite to the bottom cover portion 12b.
[0048]
The battery pack 29 shown in the figure is provided with a guide groove 13 that opens from the center of the bottom cover portion 12b to one side. The guide grooves 13 do not necessarily need to be provided on both the upper and lower surfaces of the battery pack 29 in FIGS. This is because the elastic protruding contact 6 is positioned at the approximate center of the negative electrode terminal 5 of the secondary battery 3 with the battery pack 29 placed in a fixed position in the dry battery storage unit 2.
[0049]
