[0025] Hereinafter, a battery housing structure that is one aspect of the technology of the present disclosure will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a toy 1 equipped with a battery housing structure.

[0026] The toy 1 shown in FIG. 1 applies a battery housing structure according to one embodiment of the technology disclosed herein and has a shape including a disk-shaped main body 10a and a rod-shaped grip 10b, and is played with by holding the rod-shaped grip 10b in a hand 80. It is a thin toy equipped with an internal power source and control functions, for example, to emit lines and sounds from the hero and, if necessary, to emit light. The components of this toy 1 can be broadly divided into a main body member 10, which is a first member equipped with a control system including a battery housing 14 (see FIG. 2) and a control unit for a light-emitting unit and a sound output unit, and a second member, a cover member 20, which is detachable from the main body member 10 and can cover the battery housing 14.

[0027] The cover member 20 has a first portion 21 which is a disk-shaped outer shell member with the central portion thereof protruding toward the front side, and a spherical decorative portion 21b is provided at the front tip of the first portion 21.

[0028] FIG. 2 is a perspective view of the main part of the toy 1 shown in FIG. 1 with the cover member 20 removed. As shown in FIG. 2, the first portion 21 of the cover member 20 corresponds to close a circular recess 10c formed in the center of the front side of the disk-shaped main body 10a. A pair of battery housing sections 14 for accommodating batteries 40 are provided in the circular recess 10c at positions closer to the upper side. Furthermore, a screw member 30 for fixing the cover member 20 is provided in a through-hole 15 that penetrates the main body 10 in the thickness direction at the center. The screw member 30 fixes the cover member 20 to close the circular recess 10c. That is, a screw-receiving hole 20A (see FIG. 4) into which the screw member 30 is threaded is provided at the center of the inner surface of the cover member 20. In this embodiment, the screw member 30 and the screw-receiving hole 20A each have a thread formed thereon, with the screw member 30 having a male thread and the screw-receiving hole 20A having a female thread. This allows the screw member 30 to be connected to the screw-receiving hole 20A. In addition, a thread for receiving the thread of the screw member 30 may also be formed on the inside of the through hole 15 as an auxiliary thread.

[0029] The battery accommodating section 14 has a cylindrical recessed shape that accommodates a button-type battery 40, and a contact member 14b is provided inside the battery accommodating section 14. For example, when accommodating a button-type battery 40 in the battery accommodating section 14, the battery 40 is inserted and attached from the open opening 14a side of the battery accommodating section 14 in a first direction (thickness direction of the main body member 10). At this time, the battery 40 is pushed toward the open opening 14a by the contact member 14b and is in a slightly floating state. Then, the cover member 20 is placed from above to close the battery accommodating section 14, and secured with the screw member 30, whereby the battery 40 is pushed into the battery accommodating section 14 and comes into contact with the contact member 14b, thereby being secured in a predetermined position.

[0030] The cover member 20 has a hook piece 21c protruding radially outward from one end of the first portion 21, and a positioning protrusion 21d at a position 180 degrees opposite the hook piece 21c. A pair of rectangular mating recesses 20j extending radially from the center are provided, and a pair of annular battery-retaining protrusions 20k are provided between the mating recesses 20j. Meanwhile, the circular recess 10c of the main body member 10 is provided with a hook piece receiving portion 10f and a protrusion receiving hole 10d, and a rectangular mating protrusion 10e that fits into the mating recess 20j. Therefore, when attaching the cover member 20, the hook piece 21c is inserted into the hook piece receiving portion 10f, and the positioning protrusion 21d is fitted into the protrusion receiving hole 10d, and then the cover member 20 is attached with the screw member 30. The annular protrusions 20k press the battery 40 toward the bottom of the battery housing portion 14 so that the battery 40 firmly contacts the contact member 14b.

[0031] In this embodiment, the surface of the lid member 20 is decorated, colored, or otherwise designed, and by fixing the lid member 20 to the main body member 10, a single design is formed by the surface of the lid member 20 and the surface of the main body member 10 facing the lid member 20. By making the surface of the lid member 20 part of the design (decoration, etc.) of the main body member 10 in this way, the lid member 20 can be positioned without looking out of place.

[0032] FIG. 3 is an exploded perspective view of the toy 1 shown in FIG. As shown in Fig. 3, the main body member 10 is divided in the front-rear direction and includes, for example, a rear main body portion 11 and a front main body portion 12, and is configured to be thin in the front-rear direction. The rear main body portion 11 and the front main body portion 12 are combined and fixed by recessed and protruding parts provided on their mating surfaces 10j. For example, the rear main body portion 11 is provided with a protruding strip 17 that follows the contour of the member, and further, protruding parts 18 and recessed parts 19 are appropriately distributed. On the other hand, the front main body portion 12 is provided with a recessed and protruding structure corresponding to the protruding strip 17, protruding parts 18, and recessed parts 19, although not shown.

[0033] The main body member 10 is assembled by combining the components using this interlocking structure, but may be fixed using adhesive or the like as needed. In this embodiment, the screw member 30 is primarily a member for attaching the cover member 20, but can also be used to fasten the main body member 10 once the cover member 20 is attached. Because the main body member 10 is connected in this manner without using fastening screws or the like, no fastening members such as screws are exposed on the front or back sides of the main body member 10, allowing the toy 1 to have a neat appearance.

[0034] FIG. 4 is a cross-sectional view of a portion taken along line AA in FIG. As shown in FIG. 4 , the cover member 20 is fixed by threading the tip end 30a of the screw member 30 inserted through the through hole 15 into the screw-receiving hole 20A. The screw-receiving hole 20A is located inside the approximate center of the cover member 20 when viewed from above. As described above, the cover member 20 is configured, for example, such that the second portion 22 is fitted inside the first portion 21 whose front side is closed. That is, the front side of the screw-receiving hole 20A of the cover member 20 is closed, and the tip end 30a of the screw member 30 is not visible. The screw member 30 is configured so that its base end 30b is embedded in the through hole 15, and is attached so that its base end surface 30s is located inside the back surface 11s of the main body member 10.

[0035] A control unit board 60 is provided inside the main body member 10. A switch such as a rubber switch 61 (a switch that has resilience when pressed) is provided on the back side of this board 60, and the rubber switch 61 is configured to be operable by pressing a press switch 11b on the back side of the main body member 10. Although not shown, a mode switch or the like that can change the performance mode of the toy 1 is also provided on the back side of the main body member 10.

[0036] FIG. 5 is a cross-sectional view with the cover member 20 removed. As described above, the battery accommodating section 14 has a cylindrical recessed shape, and its depth (h1) in the first direction (arrow X direction) is configured to be approximately the same as the maximum thickness (h2) of the rear main body section 11. Furthermore, the depth (h1) of the battery accommodating section 14 differs from the thickness (h3) of the main body member 10 including the front main body section 12 by only the difference in the thickness of the main body member 10, so it can be said that the depth (h1) is approximately the same size.

[0037] In this embodiment, as shown in FIG. 5 , a retaining member 24 (hereinafter referred to as the nut 24) is provided inside the screw-receiving hole 20A, into which the tip end 30a of the screw member 30 is threaded. For example, the nut 24 is housed in a space SP1 formed by the first portion 21 and the second portion 22 constituting the lid member 20. The nut 24 is held immovable in the space SP1 in a first direction (the direction of arrow X (thickness direction of the toy 1)) by being restricted in position by the tip end surface 21at of the position restricting portion 21a and the space inner wall surface 22w of the second portion 22. The nut 24 is also held immovable in the rotational direction (see FIG. 7 ). Note that, although the present embodiment employs a structure in which the retaining member 24 is provided, this is not limiting, and a screw thread that threadably engages with the screw member 30 may be formed on the first portion 21 or the second portion 22. Furthermore, although an example in which a nut is used as the retaining member 24 has been described, something other than a nut may be used.

[0038] Furthermore, the space SP1 of the screw receiving hole portion 20A is formed as a space with a larger diameter (d3) than the screw hole diameter (d1) of the nut 24, and the inner diameter (d2) of the position restricting portion 21a is also configured to be larger than the screw hole diameter (d1). With this configuration, even when the tip portion 30a of the screw member 30 is long, that is, even when the screw member 30 protrudes from the nut 24, the tip portion 30a is allowed to enter.

[0039] The maximum thickness (d4) of the lid member 20 in the first direction is greater than the maximum thickness (d3) of the main body member 10. The lid member 20 also has a bulging portion 21e that bulges forward in a spherical shape to surround the decorative portion 21b. As such, the lid member 20 is configured to be thick and has the bulging portion 21e, which increases its rigidity in the first direction.

[0040] In this embodiment, the screw member 30 is configured so as not to come off from the main body member 10. For example, the screw member 30 is provided with a small diameter portion 30c between the distal end portion 30a and the proximal end portion 30b, the small diameter portion 30c having a diameter smaller than that of the distal end portion 30a. The small diameter portion 30c is configured to have a diameter corresponding to the narrowed portion 15b of the through hole 15, so that the screw member 30 can be configured so as not to come off from the main body member 10. However, the screw member 30 may also be configured so as to come off from the main body member 10.

[0041] Fig. 6 is an exploded perspective view showing the inner structure of the first portion 21 of the cover member 20. Fig. 7 is an exploded perspective view showing the inner structure of the second portion 22 of the cover member 20. As described above, the cover member 20 is composed of two parts. As shown in FIGS. 6 and 7, the first part 21 has a cylindrical recess formed therein that defines a space SP1. A cylindrical position restricting portion 21a is provided at the center of the first part 21 and protrudes toward the second part 22. The outer periphery of the position restricting portion 21a is provided with, for example, a pair of fitting shafts 21p and a pair of ribs 21v that protrude in the same direction as the position restricting portion 21a. The fitting shafts 21p are fitted into fitting recesses 22c (see FIG. 7) provided on the inner protrusion 22a of the second part 22, and the ribs 21v determine the position at which the second part 22 is pushed in. The back side of the cover member 20 is provided with the hook pieces 21c, the positioning protrusion 21d, the pair of annular protrusions 20k, and the fitting recesses 20j, as described above.

[0042] 7, a hexagonal nut fitting recess 22b is provided within the screw receiving hole 20A. Therefore, the nut 24 is fixed so as not to rotate by fitting the outer peripheral surface 24b (hexagonal) of the nut 24 into the inner peripheral wall surface of the nut fitting recess 22b. Furthermore, by fitting the nut 24 tightly into the nut fitting recess 22b, for example, the nut 24 can be locked not only in the rotational direction but also in the first direction.

[0043] The battery housing structure of this embodiment is a novel battery housing structure in which a screw receiving hole portion 20A is provided in the second member, lid member 20. Furthermore, the body member 10 and the lid member 20 can be fixed together by a screw member inserted from the side of the first member, lid member 20. Furthermore, by configuring the screw receiving hole portion 20A so that it is not visible from the outside, the lid member 20 can be used as a decorative component.

[0044] In the battery housing structure of this embodiment, the storage depth of the battery housing section 14 is configured to be approximately the same as the maximum thickness in the first direction, so that the thickness of the first member, the main body member 10, can be made a thin member that is close to the thickness of the battery.

[0045] In the battery housing structure of this embodiment, screw receiving hole 20A is provided in the center of lid member 20, which allows lid member 20 to be reliably fixed to body member 10. Furthermore, because screw receiving hole 20A is located in the center of lid member 20, the tightening force applied by the screws can be uniform across lid member 20.

[0046] In the battery housing structure of this embodiment, the screw member 30 that attaches the cover member 20 is not exposed on the outer surface of the cover member 20, and furthermore, even on the back side of the main body member 10, it is positioned so as to be recessed from the back surface 11s, which makes it possible to provide a structure that is preferable for decorative presentation of the main body member 10.

[0047] In the battery housing structure of this embodiment, the cover member 20 is configured as a decorative part in the toy 1 so that the screw holes are not exposed, thereby allowing the toy 1 to be presented in a desirable manner.

[0048] In the battery housing structure of this embodiment, a (metallic) nut 24 is firmly attached to the screw receiving hole portion 20A of the cover member 20 that closes the battery housing section 14 so that it does not move, allowing the cover member 20 to be stably attached for a long period of time.

[0049] Furthermore, according to the battery housing structure of this embodiment, the screw receiving hole portion 20A has a space (SP1, SP2) larger than the screw hole diameter of the nut 24, so that a versatile cover member 20 can be provided that allows the use of a long-shaft screw member even when the axial length of the screw passes through the nut 24.

[0050] In the battery housing structure of this embodiment, the space SP1 of the screw receiving hole portion 20A is formed by the combination of the first portion 21 and the second portion 22, so that the nut 24 can be easily fitted into the cover member 20.

[0051] Furthermore, the nut 24 of the screw receiving hole portion 20A is firmly fixed by the position restricting portion 21a and the nut fitting recess 22b, making it easy to attach the screw member 30 and reliably tightening the lid member 20. Furthermore, the inside of the lid member 20 is provided with an annular protrusion 20k that corresponds to the battery housing portion 14 and can press against one end of the battery 40. This ensures that the battery 40 is pressed against the contact member 14b and held in a predetermined position when the lid member 20 is attached. Furthermore, the lid member 20 of the toy 1 is configured to be thick and highly rigid, allowing for increased rigidity despite its overall thinness. Furthermore, because the lid member 20 can be made highly rigid, it can reliably hold and house batteries 40 that require pressing, such as button-type batteries, even when the main body member 10 is thin.

[0052] Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the nut 24 is held by the position restricting portion 21a, but the present invention is not limited to this configuration, and the position restricting portion 21a may not be present.
