Embodiments for Carrying Out the Invention

[0025] Hereinafter, a battery housing structure which 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 provided with a battery housing structure.

[0026] The toy 1 shown in FIG. 1 applies a battery housing structure of one aspect of the technology of the present disclosure, and has a shape including a disk-shaped main body portion 10a and a rod-shaped grip portion 10b, and is played with by holding the rod-shaped grip portion 10b with the hand 80. Further, for example, it is a thin toy having a power source and a control function inside, which expresses the lines and sounds of a hero, and further expresses light as necessary. As the components of this toy 1, roughly speaking, a main body member 10 which is a first member including a control system including a battery housing portion 14 (see FIG. 2), a light emitting portion, a control portion of a voice output portion, etc., and a lid member 20 which is a second member detachable from the main body member 10 and capable of covering the battery housing portion 14 are provided.

[0027] The lid member 20 includes a first portion 21 which is an outer shell member having a disk shape and a central portion protruding to the front side, and a decorative portion 21b having a spherical shape is provided at the front tip portion of the first portion 21.

[0028] FIG. 2 is a perspective view of a main part showing a state where the lid member 20 of the toy 1 shown in FIG. 1 is removed. As shown in Fig. 2, the lid member 20 corresponds to closing the circular recessed portion 10c formed in the central portion on the front side of the disk-shaped main body portion 10a. In the circular recessed portion 10c, a pair of battery accommodating portions 14 for accommodating the battery 40 are provided at positions closer to the upper side. Also, at the central portion, a screw member 30 for fixing the lid member 20 is provided in a through hole 15 penetrating in the thickness direction of the main body member 10. By this screw member 30, the lid member 20 is fixed so as to close the circular recessed portion 10c. That is, at the center inside the lid member 20, a screw receiving hole portion 20A (see Fig. 4) into which the screw member 30 is screwed is provided. In the present embodiment, screw threads are formed on the screw member 30 and the screw receiving hole portion 20A, respectively. A male screw portion is formed on the screw member 30, and a female screw portion is formed on the screw receiving hole portion 20A. Thereby, it is possible to connect the screw member 30 to the screw receiving hole portion 20A. Note that screw threads for receiving the screw threads of the screw member 30 may also be formed inside the through hole 15 as an auxiliary measure.

[0029] The battery accommodating portion 14 has a cylindrical concave shape for accommodating the button-type battery 40, and a contact member 14b is provided inside thereof. For example, when accommodating the button-type battery 40 in the battery accommodating portion 14, it is inserted and mounted along the first direction (the thickness direction of the main body member 10) from the release port 14a side of the battery accommodating portion 14. At this time, the battery 40 is pushed by the contact member 14b and is in a slightly floating state. Then, by covering the lid member 20 from above so as to close the battery accommodating portion 14 and fixing it with the screw member 30, the battery 40 is pushed into the battery accommodating portion 14, abuts against the contact member 14b, and is fixed at a predetermined position.

[0030] The lid member 20 has a hook piece 21c protruding radially outward at one end side of the first part 21, and a positioning projection 21d is provided on the side opposite to the hook piece 21c by 180 degrees. Further, a pair of rectangular fitting recesses 20j extending radially from the central portion are provided, and further, a pair of annular projections 20k for pressing the battery are provided between the fitting recesses 20j. On the other hand, in the circular recessed portion 10c of the main body member 10, a hook piece receiving portion 10f and a projection receiving hole 10d are provided, and further, a rectangular fitting projection 10e that fits into the fitting recess 20j is provided. Therefore, when attaching the lid member 20, the hook piece 21c is inserted into the hook piece receiving portion 10f and the positioning projection 21d is fitted into the projection receiving hole 10d, and it is attached with the screw member 30. Thereby, the battery 40 is pressed against the bottom side of the battery housing portion 14 so as to be in firm contact with the contact member 14b by the annular projection 20k.

[0031] Also, in this embodiment, the lid member 20 has a design such as decoration or coloring on its surface. By fixing the lid member 20 to the main body member 10, one design is formed by the surface of the lid member 20 and the surface of the main body member 10 on the lid member 20 side. In this way, by making the surface of the lid member 20 a part of the design (decoration, etc.) of the main body member 10, the lid member 20 can be arranged without a sense of incongruity.

[0032] FIG. 3 is an exploded perspective view of the toy 1 shown in FIG. 1. As shown in FIG. 3, the main body member 10 includes, for example, a rear main body portion 11 and a front main body portion 12 that are divided in the front-rear direction, 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 uneven fitting provided on their combined surface 10j. For example, the rear main body portion 11 is provided with a rib 17 along the contour portion of the member, and further, convex portions 18 and concave portions 19 are appropriately and dispersedly arranged. On the other hand, although not shown, the front main body portion 12 is provided with an uneven structure for the ribs 17, convex portions 18, and concave portions 19.

[0033] The main body member 10 is assembled by being combined with such a fitting structure, but may be fixed using an adhesive or the like as necessary. Further, in this embodiment, the screw member 30 is exclusively a member for attaching the lid member 20, but in the state where the lid member 20 is attached, it can be used for fixing the main body member 10. Since the main body member 10 is connected without using a fastening screw or the like in this way, fastening members such as screws are not exposed on the front and back surfaces of the main body member 10, and the appearance of the toy 1 can be made beautiful.

[0034] FIG. 4 is a cross-sectional view of a portion along the line A-A in FIG. 1. As shown in FIG. 4, in the lid member 20, the tip portion 30a of the screw member 30 inserted through the through hole 15 is screwed and fixed to the screw receiving hole portion 20A. The screw receiving hole portion 20A is provided inside a substantially central portion when the lid member 20 is viewed in plan. As described above, the lid member 20 has a configuration in which, for example, the second portion 22 is fitted inside the first portion 21 with the front side closed. That is, the front side of the screw receiving hole portion 20A of the lid member 20 is closed, and the tip portion 30a of the screw member 30 is not visible. Further, the screw member 30 is configured such that its base end portion 30b is buried 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] In addition, a base 60 of the control unit is provided inside the main body member 10. On the back side of this base 60, a switch such as a rubber switch 61 (a switch having resilience against a pressing operation) is provided, and the rubber switch 61 is configured to be operable by pressing the pressing 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 effect 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 in a state where the lid member 20 is removed. The battery housing portion 14 has a cylindrical concave shape as described above. The size (h1) in the first direction (arrow X direction), which is the depth thereof, is configured to be substantially the same as the maximum thickness (h2) of the rear main body portion 11. Also, it can be said that the depth (h1) of the battery housing portion 14 is substantially the same size as the difference in wall thickness of the main body member 10 with respect to the thickness (h3) of the main body member 10 including the front main body portion 12, with only a difference of about the wall thickness difference of the main body member 10.

[0037] In the present embodiment, as shown in FIG. 5, a holding member 24 (hereinafter referred to as nut 24) is provided inside the screw receiving hole portion 20A, into which the tip portion 30a of the screw member 30 is screwed. For example, the nut 24 is accommodated in a space SP1 formed by the first portion 21 and the second portion 22 that constitute the lid member 20. And the nut 24 is held so as not to move by being positionally restricted by the tip surface 21at of the position restricting portion 21a and the inner wall surface 22w of the space of the second portion 22 in the first direction (arrow X direction (thickness direction of the toy 1)) within the space SP1. Also, it is held so as not to move in its rotational direction (see FIG. 7). In the present embodiment, the structure is provided with the holding member 24, but it is not limited thereto, and a thread that engages with the screw member 30 may be formed on the first portion 21 or the second portion 22. Also, although an example of using a nut as the holding member 24 is described, it may be other than a nut.

[0038] Also, 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). According to this configuration, when the tip portion 30a of the screw member 30 is long, that is, when the screw member 30 protrudes from the nut 24, the entry of the tip portion 30a is allowed.

[0039] The lid member 20 is configured such that the maximum thickness (d4) in the first direction is greater than the maximum thickness (d3) of the main body member 10. Further, the lid member 20 includes a bulging portion 21e that bulges forward in a spherical shape so as to surround the decorative portion 21b. Thus, the lid member 20 has a configuration with a large thickness and the bulging portion 21e, so that the rigidity in the first direction is enhanced.

[0040] In this embodiment, the screw member 30 is configured not to come off from the main body member 10. For example, the screw member 30 is provided with a small-diameter portion 30c having a smaller diameter than the tip portion 30a between the tip portion 30a and the base end portion 30b. And, by configuring the small-diameter portion 30c to have a diameter corresponding to the constricted portion 15b of the through-hole 15, the screw member 30 can be configured not to come off from the main body member 10. Note that the screw member 30 may be configured 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 lid member 20. FIG. 7 is an exploded perspective view showing the inner structure of the second portion 22 of the lid member 20. As described above, the lid member 20 is composed of two parts. The first part 21 has a cylindrical recess formed therein that forms a space SP1 inside thereof, as shown in FIGS. 6 and 7. And a cylindrical position regulating portion 21a projects toward the second part 22 at the center thereof. Further, on the outer peripheral side of the position regulating portion 21a, for example, a pair of fitting shaft portions 21p and a pair of ribs 21v project in the same direction as the position regulating portion 21a. The fitting shaft portion 21p fits into a fitting recess 22c (see FIG. 7) provided on the protruding portion 22a inside the second part 22, and the rib 21v determines the pushing position when the second part 22 is pushed in. Further, on the back surface side of the lid member 20, as described above, a hook piece 21c, a positioning projection 21d, a pair of annular projections 20k, and a fitting recess 20j are provided.

[0042] As shown in Fig. 7, a hexagonal nut fitting recess 22b is provided in the screw receiving hole portion 20A. Therefore, the nut 24 is fixed so as not to rotate by being incorporated such that the outer peripheral surface 24b (hexagonal shape) of the nut 24 fits into the inner peripheral wall surface of the nut fitting recess 22b. Further, the fitting of the nut 24 can be made, for example, in a tight fitting state with respect to the nut fitting recess 22b, so that not only the locking in the rotational direction of the nut 24 but also the locking in the first direction is possible.

[0043] The battery housing structure of this embodiment is a battery housing structure with a new structure in which a screw receiving hole portion 20A is provided in the lid member 20 which is the second member. Further, the main body member 10 and the lid member 20 can be fixed by a screw member inserted from the side of the main body member 10 which is the first member. Further, since the screw receiving hole portion 20A is configured to be not visible from the outside, the lid member 20 can be used as a decorative part.

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

[0045] In the battery housing structure of this embodiment, since the screw receiving hole portion 20A is provided in the central portion of the lid member 20, the lid member 20 can be surely fixed to the main body member 10. Further, since the screw receiving hole portion 20A is located in the central portion of the lid member 20, the tightening force by screwing can be made uniform over the entire lid member 20.

[0046] In the battery housing structure of this embodiment, the screw member 30 for attaching the lid member 20 is not exposed on the outer surface of the lid member 20, and further, on the back surface side of the main body member 10, it is positioned so as to be recessed more than the back surface 11s, so that a preferable structure can be achieved in the decorative presentation of the main body member 10.

[0047] In the battery housing structure of this embodiment, since the lid member 20 is configured as a decorative part in which the screw hole is not exposed in the toy 1, a preferable presentation can be achieved for the toy 1.

[0048] In the battery housing structure of this aspect, since the nut 24 (made of metal) is firmly attached to the screw receiving hole portion 20A of the lid member 20 that closes the battery housing portion 14 so as not to move, the lid member 20 can be stably attached over a long period of time.

[0049] Further, according to the battery housing structure of this aspect, in the screw receiving hole portion 20A, spaces (SP1, SP2) larger than the screw hole diameter of the nut 24 are provided, so that even when the axial length of the screw penetrates the nut 24, a versatile lid member 20 that allows the use of a long-axis screw member can be provided.

[0050] In the battery housing structure of this aspect, since 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, the nut 24 can be easily incorporated into the lid member 20.

[0051] Further, the nut 24 in the screw receiving hole portion 20A is firmly fixed by the position restricting portion 21a and the nut fitting concave portion 22b, so that the attachment of the screw member 30 is easy and the tightening of the lid member 20 can be surely performed. Further, inside the lid member 20, an annular projection 20k capable of pressing one end side of the battery 40 is provided corresponding to the battery housing portion 14, so that when the lid member 20 is attached, the battery 40 can be surely held at a predetermined position so as to be pressed against the contact member 14b. Further, the lid member 20 of the toy 1 is configured to have a large thickness and high rigidity, so that the rigidity can be increased while being thin as a whole. Further, since the rigidity of the lid member 20 can be increased, even if the main body member 10 is thin, reliable holding and housing can be performed even in the case of a battery 40 that requires pressing, such as a button-type battery.

[0052] As described above, one aspect of the present invention has been described, but the present invention can be appropriately modified within the scope of its technical idea. For example, in the above aspect, the nut 24 is configured to be held by the position restricting portion 21a, but the present invention is not limited to this configuration, and a configuration without the position restricting portion 21a may be used.
