[0005] In Patent Document 1, the light-transmitting body (light-emitting member) is connected and fixed to the light-emitting element. Therefore, the model toy can perform a predetermined light-emitting performance, but is not structured to move the light-transmitting body. Therefore, it is not possible to enjoy moving the light performance as a model toy. In addition, although the interest can be increased by making the light-emitting member a movable structure, there is a problem that the structure becomes more complicated. Furthermore, there is a problem that it becomes difficult to maintain the light-guiding performance of the movable structure part. In particular, in a small and lightweight structure such as a model toy, it has been difficult to provide a highly interesting model toy that has excellent light-guiding performance and can move the light-emitting member while avoiding the complication of the light-guiding structure of the movable structure.

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a light guiding structure for a model toy according to the present invention will be described with reference to the drawings.
[0023] Fig. 1 is a perspective view of the model toy 1. Fig. 2 is a front view of the model toy 1. As shown in Figs. 1 and 2, the model toy 1 is a long, plate-like plastic model structure, which is attached to, for example, a robot character 100 (not shown in its entirety) and is a model imitating a defensive shield used by the robot character 100. The model toy 1 includes a toy body including a plate-like upper cover part 1c, a lower cover part 1d, and a back part 1e on the back side of both cover parts 1c and 1d, which extend vertically from a center part 1g at the approximate center in the vertical direction. Furthermore, the model toy 1 includes a light emitting member 20 including extending wing parts 22 that extend diagonally upward and downward to the left and right from the center part 1g, in other words, extend in four directions in an X-shape, when the toy body is viewed from the front (see Fig. 2). The light emitting member 20 is configured to be rotatable around the center part 1g, the details of which will be described later.
[0024] The light emitting member 20 does not have a light source of its own, but has a function of emitting light guided by the light guiding member 10 described later so that the light can be seen from the outside. As a form of emitting light, as described later, for example, it is configured so that light can be emitted from both the front and back sides of the extending blade portion 22 of the light emitting member 20. As a light source for the light emitting member 20, for example, a light source 8 such as an LED installed on the robot character 100 side is used.
[0025] As a structure for utilizing the light from the light source 8, for example, a detachable mounting locking part 1j is provided on the back side part 1e of the toy body at a predetermined position of the robot character 100. Therefore, in a state in which the model toy 1 is attached via the mounting locking part 1j, the light receiving end part 12t (see FIGS. 4 and 5) of the light guide member 10 faces the light source 8 as shown in FIG.
[0026] FIG. 3 is an exploded perspective view of the model toy 1. As shown in FIG. As shown in FIG. 3, the light emitting member 20 is disposed between the upper cover portion 1c, the lower cover portion 1d, the center portion 1g, and the rear side portion 1e. The light guide member 10 is held in a holding hole 1eh in the rear side portion 1e. The light guide member 10 held in the holding hole 1eh has a light exit portion 11 at one end side exposed from the rear side portion 1e. The light emitting member 20 is held on the rear side portion 1e such that the central hole 21h of the annular light entrance portion 21 fits into the light exit portion 11. That is, the light emitting member 20 is held such that the light entrance portion 21 that receives light from the light guide member 10 surrounds the cylindrical light exit portion 11. The light entrance portion 21 is held rotatably with respect to the light exit portion 11.
[0027] In this manner, the structure in which the light entrance portion 21 of the light-emitting member 20 surrounds the light exit portion 11 of the light-guiding member 10 can increase the facing area between the light exit portion 11 and the light entrance portion 21, which is advantageous for increasing the amount of light guided from the light-guiding member 10 to the light-emitting member 20. In addition, since the light-guiding member 10 is used as a rotation support shaft for the light-emitting member 20, there is no need to provide a rotation support shaft.
[0028] In this embodiment, the light emitting member 20 has a total of four extending blade portions 22 capable of emitting light (made of a light-transmitting material), and is configured of two parts overlapping in the thickness direction, as described below. For example, the light emitting member 20 has a pair of extending blade portions 22 extending in opposite radial directions at 180 degrees from an annular light entrance portion 21. The two light emitting members 20 are arranged so as to overlap in the thickness direction at the light entrance portion 21 (see FIG. 6). Therefore, light can be taken in from a plurality of light entrance portions 21, and the light entrance portions 21 can move independently and separately without being linked to each other.
[0029] Fig. 4 is an enlarged perspective view of the light guide member 10. Fig. 5 is a cross-sectional view of a portion of the light guide member 10 taken along line AA in Fig. 4. As shown in FIG. 4 and FIG. 5, the light guide member 10 includes a light guide body 12 that guides the light of the light source 8 to the light output section 11. The light output section 11 is formed to have a larger diameter than the light guide body 12. The light output section 11 also has a recessed surface 11c formed on the end face opposite to the side where the light source 8 is arranged. The recessed surface 11c is configured to be recessed in, for example, a substantially conical shape. In other words, the recessed surface 11c has a top 11t located on the light source side and is configured as an inverted cone surface when viewed from the light source 8 side. Therefore, the light incident from the light guide body 12 is reflected toward the arc outer surface 11s. The reflected light of the light source 8 is radiated from the arc outer surface 11s toward the light entrance section 21.
[0030] In this way, the recessed surface 11c reflects the light from the light source 8 in a predetermined direction by positioning the apex 11t on the side where the light source 8 is arranged. Moreover, the recessed surface 11c has an inverted cone shape, so that the light can be reflected evenly in any direction of 360 degrees intersecting with the axial line CL of the light-guiding member 10. In addition, the inclination angle of the recessed surface 11c is constant (see FIG. 5), so that the reflected light can be emitted in a large amount as parallel light (light favorable for light guiding) toward the extension direction of the light-emitting member 20. Note that the apex 11t is configured in an arc shape in the figure, but in the actual model toy 1, it has an extremely small R (radius) shape. Therefore, the light from the light source 8 hardly leaks from the apex 11t.
[0031] On the outer peripheral surface 12s of the light-guiding body 12, a plurality of ridges 12d are formed at equal intervals in the circumferential direction of the outer peripheral surface 12s so as to follow the axial line CL of the light-guiding body 12. That is, although the light-guiding body 12 is configured to have a small diameter, the substantial rigidity is increased by the ridges 12d, resulting in a structure with increased strength.
[0032] In theory, it is desirable for the light-guiding member 10 to have as large a diameter as possible in accordance with the size of the light source 8, because the light-guiding cross-sectional area is increased and more light can be guided. However, if the light-guiding body 12 is made thicker in order to increase the light-guiding cross-sectional area, the resin sink during molding becomes larger and air bubbles are more likely to remain in the molded resin, reducing the light-guiding efficiency.
[0033] Therefore, although a configuration in which the diameter of the light guide body 12 is substantially smaller than the diameter of the light output section 11 may at first glance appear to reduce the light guide efficiency, it actually prevents the light guide efficiency from decreasing because it suppresses the generation of bubbles along with the resin sinking during molding. On the other hand, by providing multiple protrusions 12d on the outer peripheral surface 12s of the light guide body 12, the strength is increased as described above, and at the same time, the light guide cross-sectional area is increased, allowing more light to be guided.
[0034] In this way, compared to the case where the shape of light-guiding member 10 is a cylindrical cylinder that matches the diameter of light output section 11, it is possible to improve the light-guiding efficiency and the yield, and to stably manufacture high-quality light-guiding members 10. In addition, the light-guiding cross-sectional area of light-guiding body section 12 can be increased by ridge 12d.
[0035] The light exit portion 11 has an arcuate outer surface 11s, which is the outer circumferential surface thereof, formed with a notch 11k. The notch 11k has two notch surfaces 11ks that extend radially outward from the axial line CL side of the light-guiding member 10. That is, the notch 11k has a substantially V-shape in plan view (see FIG. 8) when viewed from the axial line CL direction, and is cut out so as to define a light-guiding path E along which light is emitted from the light-emitting portion 11. A pair of notches 11k are provided on either side of the axial line CL. A locking protrusion 1i of the back side portion 1e engages with the notch 11k, thereby locking the light-guiding member 10 so as not to rotate.
[0036] FIG. 6 is an enlarged exploded perspective view showing the mounting structure of the light guide member 10 and the light emitting member 20. As shown in FIG. As shown in Fig. 6, when assembling the light guide member 10 and the light emitting member 20, first, the light guide body 12 of the light guide member 10 is inserted into the holding hole 1eh as described above. At this time, the light guide member 10 is attached so that the notch 11k fits into the locking protrusion 1i. After that, the two light emitting members 20 are fitted into the light exiting portion 11 so that the light entrance portions 21 overlap. At this time, the light guide member 10 and the light emitting member 20 are attached so that the restricting protrusions 1w fit into a pair of openings 21w formed as notches on the edge of the central hole 21h.
[0037] FIG. 7 is an exploded perspective view showing the assembled state of the light guide member 10 and the light emitting member 20. As shown in FIG. As shown in Fig. 7, the light guide member 10 is engaged with the engaging protrusions 1i, and is attached so that the light entrance portion 21 of the light emitting member 20 surrounds the periphery of the light guide member 10. The light emitting member 20 is provided so that the two light entrance portions 21 overlap in the thickness direction. In this state, the pair of fitting protrusions 1gd (one of which is not shown) of the center portion 1g shown in Fig. 6 are inserted into the fixing bosses 1ed of the back side portion 1e, whereby the light emitting member 20 is attached so as to be rotatable with respect to the light guide member 10.
[0038] As shown in the figure, both the locking protrusion 1i and the restricting protrusion 1w are integrally formed as a protrusion f that is continuous in a T-shape in a plan view. The locking protrusion 1i that engages with the light guide member 10 locks the light guide member 10 as described above. On the other hand, the restricting protrusion 1w that is received in the opening 21w of the light entrance portion 21 is disposed in a so-called loose fit state with a gap in the circumferential direction of the light entrance portion 21 relative to the opening 21w. Therefore, the restricting protrusion 1w functions as a rotation position restricting member that allows the light emitting member 20 to rotate by the gap.
[0039] FIG. 8 is an enlarged plan view of the attachment portion of the light emitting member 20 as viewed from the direction of the axial line CL of the light guide member 10. As shown in FIG. 8, the light-inlet portion 21 of the light-emitting member 20 is annular and surrounds the light-outlet portion 11 as described above, but a pair of left and right notches 11k in the figure define a light guide range, i.e., a light guide path E. This light guide path E is configured to have a range of a predetermined angle within which each of the two extension blade portions 22 rotates. In detail, the range of the light guide path E is determined by the notch surface 11ks of the notch 11k.
[0040] The four extension blades 22 extending radially outward from the light entrance section 21 can be positioned within the range of the light guide path E. In addition, in Fig. 8, the positions of the openings 21w of the light entrance sections 21 overlapping in the direction perpendicular to the paper surface (see Fig. 7) are arranged such that the opening positions of the lower opening 21w (shown by dotted lines) and the upper opening 21w (shown by solid lines) are shifted by a predetermined angle as shown. This allows the overlapping light entrance sections 21 to move independently by a maximum angle (θ) (the state shown in Fig. 8 shows the state in which the extension blades 22 are fully open).
[0041] In addition, even when the extension blade portion 22 is opened to the maximum angle (θ), the position of the extension blade portion 22 is within the range of the light guide path E as shown in the figure. Therefore, the structure is such that light is reliably incident on the extension blade portion 22. Furthermore, the direction of the cutout surface 11ks that determines the light guide path E faces the extension direction of the extension blade portion 22. This prevents unnecessary dispersion of light and allows the reflected light to be efficiently directed to the extension blade portion 22.
[0042] Furthermore, because notch 11k defines light guide path E, naturally, as shown in the figure, notch 11k forms a non-light guide region (the left and right regions sandwiched between the upper and lower light guide paths E in FIG. 8) that does not guide light other than that of light guide path E. The above-mentioned protrusion 1f is provided in this non-light guide region. In this way, since protrusion 1f (locking protrusion 1i and restricting protrusion 1w) is provided in the non-light guide region, its shape can be relatively freely determined, and there is no decrease in light guide efficiency or light guide failure.
[0043] FIG. 9 is an exploded perspective view of the light emitting member 20. As shown in FIG. 9, the extension blade portion 22 has two overlapping members 22a, 22b that can be separated in the thickness direction. For example, the two overlapping members 22a, 22b have a plurality of engagement pieces 22t protruding from one end side. The engagement pieces 22t are arranged in a row on one end side when the overlapping members 22a, 22b are overlapped.
[0044] This engagement piece 22t is pressed from the thickness direction, thereby fixing the overlapping members 22a, 22b and assembling the extending blade portion 22. That is, the extending blade portion 22 is assembled by inserting and fitting the engagement piece 22t into the fixing groove 23g of the blade fixing portion 23. Note that, although the overlapping members 22a, 22b are made of a light-transmitting material, the blade fixing portion 23 does not have to be made of a light-transmitting material.
[0045] FIG. 10 is a partial cross-sectional view of the light emitting member 20. As shown in FIG. As shown in FIG. 10, the extension wing portion 22 is provided with a light reflecting portion 22r on the inner side of the overlapping members 22a and 22b. The light reflecting portion 22r is provided in the middle portion of the extension wing portion 22 in the thickness direction. The light reflecting portion 22r can have a groove structure (see FIG. 9) that extends in a direction intersecting the light path direction. The cross-sectional shape of the groove structure is, for example, a substantially triangular uneven shape. This allows a reflection surface to be formed that reflects the light incident on the extension wing portion 22 (light traveling parallel to the plate surface of the extension wing portion 22) in the thickness direction of the extension wing portion 22. In this embodiment, the light reflecting portion 22r is provided on the inner side of the overlapping members 22a and 22b, so that the presence of the light reflecting portion 22r does not affect the appearance of the extension wing portion 22 (the reality as a robot character).
[0046] In addition, the extension blade portion 22 has the light reflecting portion 22r in the middle portion in the thickness direction, so that the portion closer to the outer surface in the thickness direction is a portion where the light tends to travel in a straight line. Therefore, in the portion closer to the outer surface in the thickness direction (the portions above and below the light reflecting portion 22r in the figure), the light travels in a straight line and reaches the tip side of the extension blade portion 22.
[0047] 10, the height of the projections and recesses of the light reflecting portion 22r is the same along the longitudinal direction of the extending blade portion 22. However, the projections and recesses can be made small on the base side of the extending blade portion 22, and the height of the projections and recesses of the light reflecting portion 22r can be gradually increased toward the tip side. In this case, not only can the amount of light reaching the tip side of the extending blade portion 22 be increased, but also the light emission along the longitudinal direction of the extending blade portion 22 can be made uniform.
[0048] FIG. 11 is an enlarged cross-sectional view showing a modified example of the light guide member 10. As shown in FIG. In the case of the modified example shown in Fig. 11, the configuration includes a recessed surface 11c and a notch 11k, similar to the configurations shown in Fig. 4 and Fig. 5. In this case, the shape of the recessed surface 11c may be the inverted cone shape (see Figs. 4 and 5) described above, but as shown in Fig. 12, it can be a curved surface having an appropriate curvature so as to bulge toward the arc outer surface 11s. Note that the notch 11k can be used as a structure for easily fixing the light-guiding member 10, similar to the configurations described above.
[0049] By forming the recessed surface 11c as a curved surface, the radiation direction of the reflected light by the recessed surface 11c can be expanded so as to follow the curvature of the arcuate outer surface 11s. In this case, the surface shape of the arcuate inner surface 21s (see FIG. 5) of the light entrance portion 21 can be a shape that surrounds the arcuate outer surface 11s, that is, a curved surface consisting of a part of a sphere that follows the arcuate outer surface 11s. In this configuration, the light entrance portion 21 not only rotates around the light guide body 12 along a plane, but also easily swings in the thickness direction of the light entrance portion 21.
[0050] In this modification, the surface structure of the top 11t is configured as a large curved surface or a flat surface. In this case, a predetermined amount of light can be transmitted through the top 11t. Therefore, the light output section 11 in this case can guide the light toward, for example, the center section 1g, other than the extended blade section 22, and the variety of light effects can be increased.
[0051] As described above, according to the light guide structure of the model toy 1 of the present embodiment, it is possible to provide a light guide structure that allows the light emitting member 20 to rotate relative to the light guide member 10. In addition, since the light entrance portion 21 of the light emitting member 20 is provided so as to surround the light exit portion 11 of the light guide member 10, the facing area between the light exit portion and the light entrance portion can be increased, and the light guide efficiency can be improved and the amount of light guided can be increased. As a result, the light emitting member 20 can provide a good light emission effect even if the amount of light emitted by the light source 8 is small. Furthermore, since the light entrance portion 21 is rotatably supported by the light exit portion 11, there is no need for a special support member required for rotation, and the rotation structure can be simplified. As a result, the movement structure of the light emitting member 20 is not complicated, and a light guide structure of the model toy 1 that is excellent in assembling and manufacturability can be provided.
[0052] Furthermore, in the light guide structure of the model toy 1 of this embodiment, the light output section 11 has a recessed surface 11c on the end surface opposite to the side where the light source 8 is arranged, and the apex 11t of this recessed surface 11c is located on the light source 8 side, so that the interface formed by the recessed surface 11c can reflect the light of the light source 8 in any direction of 360 degrees that intersects with the axial line CL of the light guide member 10. As a result, the light emitting member 20 can be arranged in any position of 360 degrees around the light output section 11, and the movable range of the light emitting member 20 can be set to be large.
[0053] In the light guide structure of the model toy 1 of this embodiment, the recessed surface 11c of the light output portion 11 is in an inverted cone shape, so that the recessed surface 11c can efficiently reflect light in a certain direction and can provide uniform reflection in all directions. In addition, the apex 11t is formed small and dot-like, so that light leakage from the apex 11t is prevented and the light in the light guide body 12 can be efficiently reflected.
[0054] In the light guide structure of the model toy 1 of this embodiment, the light entrance section 21 has an arc inner surface 21s that is always facing and movable with respect to the arc outer surface 11s of the light exit section 11, and therefore the arc outer surface 11s and the arc inner surface 21s can rotate in an arc direction along both inner and outer surfaces 11s, 21s. Moreover, since stable light can always be supplied to the arc inner surface 21s from the arc outer surface 11s, the light emitting member 20 can receive a stable amount of light even when it moves. As a result, the light emitting member 20 can obtain stable light emitting performance even when it rotates in an arc relative to the light guiding member 10.
[0055] Furthermore, in the light guide structure of the model toy 1 of this embodiment, a notch 11k is formed in the arcuate outer surface 11s of the light output portion 11, and by engaging the locking protrusion 1i with this notch 11k, the rotation of the light guide member can be fixed.
[0056] In the light guide structure of the model toy 1 of this embodiment, the notch 11k is configured in a substantially V-shape with two notch surfaces 11ks that spread radially outward from the axial center side of the light guide member, so that the notch surfaces 11ks can be used as reflecting surfaces. As a result, the notch surfaces 11ks function as light reflecting surfaces, and can efficiently guide light in a predetermined direction while avoiding unnecessary diffusion of light.
[0057] Furthermore, in the light guide structure of the model toy 1 of this embodiment, the locking protrusion 1i and the regulating protrusion 1w are positioned on the rear side of the cutout surface 11ks (the side viewed from the direction in which light is emitted at the light entrance portion 21), so that the locking protrusion 1i and the regulating protrusion 1w are positioned away from the light guide path E and are configured so as not to interfere with light guide.
[0058] In the light guide structure of the model toy 1 of this embodiment, the light exit section 11 is formed with a larger diameter than the light guide body section 12, so even if the light guide body section 12 is a thin member, the light exit section 11 is large, so the light entrance section 21 can be made large, and it is easy to ensure a light entrance path. Also, since the light exit section 11 is configured to be large, it is easy to configure the structure to provide multiple light entrance sections 21. Furthermore, since the light exit section 11 is configured to be large, it becomes easier to manufacture the engagement portion between the light exit section 11 and the light entrance section 21, and the molding precision of the rotation structure between the light exit section 11 and the light entrance section 21 can also be improved.
[0059] In addition, in the light-guiding structure of the model toy 1 of this embodiment, the strength of the light-guiding body 12 can be increased by forming a plurality of ridges 12d on the outer peripheral surface 12s of the light-guiding body 12. In addition, the plurality of ridges 12d can increase the light-guiding cross-sectional area, and can contribute to substantially increasing the amount of light guided.
[0060] In the light-guiding structure of the model toy 1 of this embodiment, the light-emitting member 20 has a light-entering section 21 that can rotate around the light-exiting section 11, and has a plurality of extending blade sections 22 that extend radially outward from this light-entering section 21, so that the extending blade sections 22 that extend in all directions create a light effect with movement that can be enjoyed.
[0061] In addition, in the light guide structure of the model toy 1 of this embodiment, since a plurality of light entrance sections 21 are provided so as to overlap in the thickness direction, each of the light entrance sections 21 can be rotated independently. Also, a larger number of extension blade sections 22 can be provided, and light effects by the multiple extension blade sections 22 can be enjoyed.
[0062] In the light guide structure of the model toy 1 of this embodiment, the extending blade portion 22 is provided with the light reflecting portion 22r along its longitudinal direction, so that the extending blade portion 22 can be illuminated on both the front and back sides over its entire length. Also, since the light reflecting portion 22r is formed in the middle portion in the thickness direction of the extending blade portion 22, the area closer to the outer surface in the thickness direction functions as a portion through which light easily travels in a straight line, so that the light can be guided to the tip side of the extending blade portion 22. As a result, the extending blade portion 22 can be illuminated well not only from its extension base but also from its tip side, enhancing the light presentation effect.
[0063] In the light guide structure of the model toy 1 of this embodiment, the extending blade portion 22 is formed by overlapping two overlapping members 22a, 22b in the thickness direction, so that the light reflecting portion 22r can be easily formed. If the unevenness of the light reflecting portion 22r is on the outer surface of the extending blade portion 22, there is a risk of impairing the reality of the robot character. However, in this embodiment, the unevenness is formed on the inner surface of the extending blade portion 22, so that the light emitting performance can be improved without impairing the appearance of the extending blade portion 22.
[0064] Further, in the above embodiment, the recessed surface 11c of the light exit portion 11 is configured as an inverted conical surface, but this is not limited thereto, and it may be configured in various shapes, such as a pyramidal surface, a spherical surface, or a polygonal surface.
[0065] In the above embodiment, the opening 21w is formed as a notch-like opening that is continuous with the central hole 21h, but the present invention is not limited to this configuration. For example, the opening 21w may be an independent hole-like opening that is not continuous with the central hole 21h.
[0066] In the above embodiment, the locking projection 1i and the restricting projection 1w are integrally formed as part of the projection f, but this is not limiting and they may be separate, independent projection structures.
[0067] In the above embodiment, the light reflecting portion 22r is configured as a sawtooth-like concave-convex groove, but may also be configured as a concave-convex groove such as a grained groove. [Explanation of symbols]
