Summary of the Invention
Problems to be Solved by the Invention
[0004] The rotating toy described in Patent Document 1 can attract the attention of infants by the rotation of the strip and the decorative parts, but since it is not something that can be rotated by hand, it cannot be said to be something that can arouse the curiosity of infants. In this rotating toy, although it is conceivable to rotate the decorative parts by hand, since the decorative parts are arranged at a floating position in the air, infants who cannot turn over, infants who can turn over but cannot crawl, or infants who can crawl but cannot stand up cannot touch the decorative parts well. Therefore, it cannot arouse the curiosity of infants.
[0005] Therefore, an object of the present invention is to provide a rotating toy for infants that can arouse the curiosity of infants.
Means for Solving the Problems
[0006] [1] The rotating toy for infants according to the present invention includes a base portion and a rotating portion disposed on the base portion and rotatably provided with respect to the base portion.
[0007] In this rotating toy for infants, the rotating part is positioned on the base so as to be able to rotate relative to the base. This makes it easy for infants who cannot roll over, those who can roll over but cannot crawl, and those who can crawl but cannot stand to reach the rotating part and easily touch and rotate it with their own hands. Therefore, it can stimulate the curiosity of infants.
[0008] [2] In the rotating toy for infants described in [1], the rotating part is mounted on a base, and the axis of rotation of the rotating part may extend in the direction on which the rotating part is mounted relative to the base. In this rotating toy for infants, since the rotating part is mounted on a base and the axis of rotation of the rotating part extends in the direction on which the rotating part is mounted relative to the base, the rotating part can be placed at a low position and can be turned by touching it from any position around the axis of rotation. This makes it easier for infants who cannot roll over, infants who can roll over but cannot crawl, and infants who can crawl but cannot stand to reach the rotating part and turn it.
[0009] [3] In the infant spinning toy described in [1] or [2], the base portion extends along a reference plane, and the axis of rotation of the spinning part may extend in a direction perpendicular to the reference plane. In this infant spinning toy, since the base portion extends along a reference plane and the axis of rotation of the spinning part extends in a direction perpendicular to the reference plane, the spinning part can be placed at a low position, and the spinning part can be touched and turned from any position around the axis of rotation. This makes it easier for infants who cannot roll over, infants who can roll over but cannot crawl, and infants who can crawl but cannot stand to reach the spinning part and turn it.
[0010] [4] In the infant spinning toy described in any of [1] to [3], the base portion may have an annular guide rail that guides the rotation of the spinning part. In this infant spinning toy, since the base portion has an annular guide rail that guides the rotation of the spinning part, the spinning part can be rotated stably.
[0011] In the rotating toys for infants and toddlers described in [5] and [4], the rotating part may be mounted on a guide rail. In this rotating toy for infants and toddlers, the rotating part is mounted on a guide rail, which allows the rotating part to rotate more stably.
[0012] [6] The infant spinning toy described in [5] further comprises a bearing positioned between the base and the rotating part, and the rotating part is mounted on a guide rail via the bearing. In this infant spinning toy, since the rotating part is mounted on a guide rail via a bearing positioned between the base and the rotating part, even infants with little strength can smoothly rotate the rotating part relative to the base with little force.
[0013] [7] In the rotating toy for infants described in any of [1] to [6], the rotating part may have a dome-shaped section. In this rotating toy for infants, the rotating part has a dome-shaped section, making it easier for infants to touch the rotating part and preventing the rotating part from hitting the infant's hand.
[0014] In the rotating toys for infants described in [8] and [7], the dome portion may be transparent. In this rotating toy for infants, because the dome portion is transparent, the inside of the rotating part can be seen through the dome portion. For this reason, for example, by putting objects or drawing pictures inside the rotating part, it is possible to attract the interest of infants.
[0015] In the rotating toy for infants described in [9] and [8], the dome portion is formed in a hollow dome shape, and multiple lenses may be formed on the inner surface of the dome portion. In this rotating toy for infants, because the dome portion is formed in a hollow dome shape and multiple lenses are formed on the inner surface of the dome portion, complex patterns and gloss can be projected onto the dome portion. Moreover, by rotating the rotating part, the dome portion can be made to sparkle. This can further stimulate the curiosity of infants.
[0016] In the rotating toy for infants described in
[10] [8] or [9], a mirrored sheet may be further provided in the hollow part of the rotating section. In this rotating toy for infants, since the mirrored sheet is provided in the hollow part of the rotating section, the rotating section can be made to appear glossy. For example, if multiple lenses are formed on the inner surface of the rotating section, rotating the section will make it sparkle even more due to the reflected light from the mirrored sheet. This can further stimulate the curiosity of infants.
[0017]
[11] The infant spinning toy described in any of [1] to
[10] may further include a stand that is detachably attached to the base and tilts the base. In this infant spinning toy, by attaching the stand to the base, the axis of rotation of the spinning part can be tilted, so that even infants who have difficulty moving their hands up and down can easily spin the spinning part. On the other hand, by removing the stand from the base, the spinning part can be rotated stably, and the infant spinning toy can be made smaller and easier to store. [Effects of the Invention]

Mode for Carrying Out the Invention
[0020] Hereinafter, a rotating toy for infants according to an embodiment will be described with reference to the drawings. In each figure, the same or corresponding elements are denoted by the same reference numerals, and duplicate descriptions are omitted.
[0021] Figure 1 is a perspective view of a rotating toy for infants according to an embodiment. Figure 2 is a front view of the rotating toy for infants shown in Figure 1. Figure 3 is a top view of the rotating toy for infants shown in Figure 1. Figure 4 is a bottom view of the rotating toy for infants shown in Figure 1. Figure 5 is a cross-sectional view along line VV shown in Figure 3. Figure 6 is an exploded cross-sectional view of the rotating toy for infants in the same cross-section as Figure 5. As shown in Figures 1 to 6, the rotating toy for infants 1 comprises a base 2, a rotating part 3, a bearing 4, a cover 5, and a pair of stands 6. The rotating toy for infants 1 is a toy that is played with by placing it on a bed or floor, for example, and rotating the rotating part 3. The axis of rotation of the rotating part 3 is called the axis of rotation A.
[0022] The base portion 2 is the part that is placed on a mounting surface B (see Figure 2), such as a bed or floor. The base portion 2 extends along the reference plane C. The reference plane C is a virtual plane that extends approximately parallel to the mounting surface B when the infant rotating toy 1 is placed on the mounting surface B. When we say that the base portion 2 extends along the reference plane C, we mean that the base portion 2 extends along the reference plane C when viewed as a whole. For this reason, the base portion 2 may have parts that do not extend along the reference plane C. For example, the base portion 2 may be formed in a thin plate shape that is intricately curved, bent, branched, etc. by resin injection molding, and may extend along the reference plane C when viewed as a whole. The rotation axis A extends in a direction perpendicular to the reference plane C. The direction in which the rotation axis A extends is called the rotation axis direction D. Of the rotation axis directions D, one direction is called the first rotation axis direction D1, and the other direction is called the second rotation axis direction D2.
[0023] Figure 7 is a plan view of the base portion. As shown in Figures 5 to 7, a boss portion 21, an inner guide rail 22, and an outer guide rail 23 are formed on the upper surface 2a of the base portion 2 on the side of the first rotation axis direction D1.
[0024] The boss portion 21 is the part that positions the rotating portion 3. The boss portion 21 is formed in a cylindrical shape centered on the rotation axis A and protrudes in the direction D1 of the first rotation axis. A through hole 24 is formed in the radial center of the boss portion 21, penetrating in the direction D of the rotation axis.
[0025] The inner guide rail 22 and the outer guide rail 23 are parts that guide the rotation of the rotating part 3. The inner guide rail 22 and the outer guide rail 23 are formed in an annular shape around the rotation axis A, such that the rotation axis A extends in a direction perpendicular to the reference plane C. The outer guide rail 23 is formed with a larger diameter than the inner guide rail 22 and is positioned on the outer edge side of the inner guide rail 22. In other words, the inner guide rail 22 and the outer guide rail 23 are arranged concentrically around the rotation axis A.
[0026] Figure 8 is a bottom view of the base. As shown in Figures 4 to 6 and Figure 8, the lower surface 2b of the base 2 on the side of the second rotation axis direction D2 has a plurality of feet 25, a plurality of receiving recesses 26, and a plurality of mounting recesses 27.
[0027] The foot portion 25 is the part that comes into contact with the mounting surface B. The foot portion 25 is provided, for example, at each of the four corners of the bottom surface of the base portion 2. The foot portion 25 may be made of a material with a high coefficient of friction, such as rubber.
[0028] The housing recess 26 is a part that detachably houses the stand 6. The housing recess 26 is provided corresponding to each of the pair of stands 6. In this embodiment, the housing recess 26 is formed by a recess in the lower surface 2b of the base portion 2. The stand 6 can be housed in the housing recess 26 by pushing the stand 6 into the housing recess 26. The housing recess 26 does not need to have a shape that corresponds to the entire outer shape of the stand 6, but it is sufficient that it has a shape that corresponds to at least a part of the outer shape of the stand 6.
[0029] The mounting recess 27 is the part into which the stand 6, which has been removed from the housing recess 26, is detachably mounted. The mounting recess 27 is provided corresponding to each of the pair of stands 6. The mounting recess 27 is formed by a recess in the lower surface 2b of the base portion 2. The stand 6 can be mounted by pushing the stand 6 into the mounting recess 27. The mounting recess 27 does not need to have a shape that corresponds to the entire outer shape of the part of the stand 6 that is pressed into the mounting recess 27, but it is sufficient that it has a shape that corresponds to at least a part of the outer shape of the part of the stand 6 that is pressed into the mounting recess 27.
[0030] As shown in Figures 1-3, 5, 6, and 8, the rotating part 3 is the part that is rotated by the infant. The rotating part 3 is positioned on the base part 2 and is rotatably mounted relative to the base part 2. The rotating part 3 is mounted on the side of the base part 2 in the direction of the first rotation axis D1. The rotation axis A of the rotating part 3 extends in the direction in which the rotating part 3 is mounted relative to the base part 2, that is, in the direction of the first rotation axis D1.
[0031] The rotating part 3 is formed in a hollow dome shape. Examples of dome shapes include a hemispherical shape, or an elliptical hemispherical shape which is the shape of an ellipsoid cut in half. A hollow part 31 is formed inside the rotating part 3. The rotating part 3 comprises a main body part 7 and a bottom part 8.
[0032] The main body 7 is the part that infants and toddlers touch and turn with their hands. The main body 7 is formed in a hollow dome shape that is open in the direction of the second rotation axis D2. In other words, the main body 7 forms a hollow section 31 that is open in the direction of the second rotation axis D2.
[0033] The main body 7 is transparent. Here, the main body 7 is said to be transparent to the extent that it has light transmittance such that an infant can vaguely see the light emitted or reflected from inside the main body 7, the color inside the main body 7, the patterns applied inside the main body 7, etc. The main body 7 may be completely transparent or it may be semi-transparent. Furthermore, the main body 7 may be colorless transparent or it may be colored transparent.
[0034] The main body 7 has a dome portion 71 and a flange portion 72. The dome portion 71 is formed in a hollow dome shape that is open in the direction of the second rotation axis D2. The flange portion 72 extends from the edge of the dome portion 71 in a flange shape, that is, in a direction away from the rotation axis A.
[0035] Multiple ribs 73 are formed on the outer surface 71a of the dome portion 71. The ribs 73 are formed by raising the outer surface 71a of the dome portion 71. The ribs 73 extend in a direction intersecting the rotation direction E of the rotating portion 3, for example, in a direction perpendicular to the rotation direction E of the rotating portion 3. The rotation direction E is the direction around the rotation axis A.
[0036] Multiple lenses 74 are formed on the inner surface 71b of the dome portion 71. The lenses 74 are formed by raising the inner surface 71b of the dome portion 71. The multiple lenses 74 are arranged, for example, in a honeycomb pattern. The multiple lenses 74 may be formed on the entire inner surface 71b of the dome portion 71, or on only a part of the inner surface 71b of the dome portion 71. The drawing shows the case where the multiple lenses 74 are formed on only a part of the inner surface 71b of the dome portion 71.
[0037] Patterns 75, such as pictures or sculptures, may be formed on the outer surface of the dome portion 71. For example, if multiple lenses 74 are formed only on a part of the inner surface 71b of the dome portion 71, patterns, pictures, etc., may be formed on the outer surface of the dome portion 71 that does not overlap with the multiple lenses 74.
[0038] Multiple through holes 76 are formed in the dome portion 71. A decorative portion 9 passes through each of the multiple through holes 76.
[0039] The decorative part 9 is an ornament attached to the dome part 71. The decorative part 9 comprises a protruding part 91 and a fixing part 92. The protruding part 91 is a part that protrudes from the outer surface of the dome part 71. The decorative part 9 is formed in a shape that imitates, for example, all or part of, an animal character in order to attract the attention of infants. The fixing part 92 is a part that is fixed to the dome part 71. The fixing part 92 penetrates the dome part 71 by being inserted into the through hole 76. The fixing part 92 is then fixed to the dome part 71 on the inner surface 71b side of the dome part 71.
[0040] The fixing portion 92 to the dome portion 71 can be fixed, for example, by forming a screw hole in the inner surface 71b of the dome portion 71 and screwing the fixing portion 92 into this screw hole. Alternatively, the fixing portion 92 to the dome portion 71 can be fixed, for example, by dividing the fixing portion 92 into an insertion portion that is inserted into the through hole 76 and a contact portion that abuts against the inner surface 71b of the dome portion 71, inserting the insertion portion into the through hole 76, and then connecting the contact portion to the insertion portion, thereby sandwiching the dome portion 71 between the protruding portion 91 and the contact portion of the fixing portion 92.
[0041] A string-like member (not shown), such as a ribbon, may be attached to the decorative part 9. The string-like member may be inserted through a through hole 93 formed in the protruding part 91 and the fixing part 92, and fixed to the fixing part 92 on the inner surface 71b side of the dome part 71.
[0042] Figure 9 is a bottom view of the bottom. As shown in Figures 5, 6, and 9, the bottom 8 is fixed to the main body 7 and forms the bottom of the hollow section 31. The bottom 8 can be fixed to the main body 7, for example, by screw fastening. The bottom 8 is positioned in the direction D2 of the second rotation axis of the hollow section 31 and covers the hollow section 31 of the main body 7 from the side in the direction D2 of the second rotation axis. A boss receiving portion 81, an inner guide rail 82, and an outer guide rail 83 are formed on the lower surface 8a of the bottom 8 on the side in the direction D2 of the second rotation axis.
[0043] The boss receiving portion 81 is the part into which the boss portion 21 of the base portion 2 is inserted to position the rotating portion 3. The boss receiving portion 81 is a cylindrical recess that extends in the direction of the rotation axis D, with the rotation axis A as its center. A screw hole 84 is formed in the radial center of the boss receiving portion 81, penetrating in the direction of the rotation axis D.
[0044] A locking member 85 is attached to the bottom portion 8 to rotatably hold the base portion 2 relative to the bottom portion 8. The locking member 85 is formed to be larger in diameter than the through hole 24 of the base portion 2 and is screwed into the screw hole 84.
[0045] The inner guide rail 82 is formed at a position opposite the inner guide rail 22 of the base portion 2 in the direction of the rotation axis D, and together with the inner guide rail 22 of the base portion 2, it guides the rotation of the rotating portion 3. The outer guide rail 83 is formed at a position opposite the outer guide rail 23 of the base portion 2 in the direction of the rotation axis D, and together with the outer guide rail 23 of the base portion 2, it guides the rotation of the rotating portion 3. The inner guide rail 82 and the outer guide rail 83 are formed in an annular shape centered on the rotation axis A, such that the rotation axis A extends in a direction perpendicular to the reference plane C. The outer guide rail 83 is formed with a larger diameter than the inner guide rail 82 and is positioned on the outer edge side of the inner guide rail 82. In other words, the inner guide rail 82 and the outer guide rail 83 are arranged concentrically around the rotation axis A.
[0046] A mirror-finish sheet 10 is placed in the hollow portion 31 of the rotating part 3. The mirror-finish sheet 10 is a sheet in which at least a portion of the upper surface 10a facing the first rotation axis direction D1 is a mirror surface. The mirror surface may be the entire upper surface 10a or only a portion of the upper surface 10a. Here, a mirror surface refers to a surface that reflects light. The mirror surface may be a colorless mirror surface like a mirror, or a colored mirror surface like an aurora sheet. The mirror-finish sheet 10 is placed on the bottom portion 8. The mirror-finish sheet 10 may simply be placed on the bottom portion 8, may be attached to the bottom portion 8, or may be screwed to the bottom portion 8.
[0047] Multiple beads 11 are housed in the hollow section 31 of the rotating section 3. The beads 11 are components that move freely within the hollow section 31. The beads 11 are housed in the space between the mirror-finish sheet 10 and the dome section 71 within the hollow section 31.
[0048] Figure 10 is a plan view of the bearing. As shown in Figures 5, 6, and 10, the bearing 4 is positioned between the base portion 2 and the rotating portion 3. The bearing 4 is, for example, a ball bearing. The bearing 4 comprises a plurality of balls 41 and a retaining portion 42 that rotatably holds the plurality of balls 41. The thickness of the retaining portion 42 in the direction of the rotation axis D is smaller than the diameter of the balls 41. The retaining portion 42 has a boss hole 43, a plurality of inner ball retaining portions 44, and a plurality of outer ball retaining portions 45.
[0049] The boss hole 43 is the part into which the boss portion 21 of the base portion 2 is inserted to position the bearing 4. The boss hole 43 is a hole centered on the rotation axis A and penetrates the holding portion 42 in the direction of the rotation axis D.
[0050] The inner ball holding portion 44 is formed in such a position that when the boss portion 21 of the base portion 2 is inserted into the boss hole 43, the ball 41 fits into the inner guide rail 22 of the base portion 2 and the inner guide rail 82 of the bottom portion 8. The outer ball holding portion 45 is formed in such a position that when the boss portion 21 of the base portion 2 is inserted into the boss hole 43, the ball 41 fits into the outer guide rail 23 of the base portion 2 and the outer guide rail 83 of the bottom portion 8.
[0051] Therefore, the bearing 4 supports the rotating part 3 with respect to the inner guide rail 22 and outer guide rail 23 of the base part 2. In other words, the rotating part 3 is placed on the inner guide rail 22 and outer guide rail 23 of the base part 2 via the multiple balls 41 of the bearing 4. The bearing 4 is positioned between the base part 2 and the bottom part 8, and the boss portion 21 of the base part 2 is inserted into the boss receiving portion 81 of the bottom part 8 through the boss hole 43 of the bearing 4, with the balls 41 held in the inner ball holding portion 44 fitting into the inner guide rail 22 of the base part 2 and the inner guide rail 82 of the bottom part 8, and the balls 41 held in the outer ball holding portion 45 fitting into the outer guide rail 23 of the base part 2 and the outer guide rail 83 of the bottom part 8. In addition, the locking member 85 is screwed into the screw hole 84 so as to sandwich the base part 2 and the bearing 4 between itself and the bottom part 8.
[0052] As shown in Figures 1-3, 5, and 6, the cover 5 covers the peripheral edge of the flange portion 72 of the main body 7 from the first rotation axis direction D1. The cover 5 has a fixing portion 51 and a cover portion 52. The fixing portion 51 is a part that is arranged around the main body 7 in a plan view and is fixed to the base portion 2. The fixing portion 51 to the base portion 2 can be fixed, for example, by screwing. The cover portion 52 is a part that covers the peripheral edge of the flange portion 72 from the first rotation axis direction D1. The cover portion 52 extends from the fixing portion 51 to the vicinity of the dome portion 71 and the rib 73 so as not to come into contact with the dome portion 71 and the rib 73. In addition, to prevent infants' hands from touching the edge of the cover portion 52, the peripheral edge 53 of the cover portion 52 is curved in an inverted U shape in cross-section and is oriented in the second rotation axis direction D2 toward the flange portion 72.
[0053] Figure 11 is a perspective view showing a pair of stands. Figure 12 is a side view of a rotating toy for infants with the pair of stands attached. Figure 13 is a cross-sectional view of the rotating toy for infants with the pair of stands attached. As shown in Figures 4 to 6 and Figures 11 to 13, the pair of stands 6 are detachably attached to the base 2 and tilt the base 2. In other words, the pair of stands 6, when attached to the base 2, tilt the rotation axis A and the reference plane C to a predetermined angle. The stand 6 has a mounting part 61 and a stand part 62.
[0054] The mounting portion 61 is a part that is detachably attached to the mounting recess 27. The mounting portion 61 is detachably attached to the mounting recess 27 by being pressed into the mounting recess 27.
[0055] The stand portion 62 is the part that tilts the base portion 2 at a predetermined angle when the mounting portion 61 is mounted in the mounting recess 27. For example, when the mounting portion 61 is mounted in the mounting recess 27, the stand portion 62 extends from the base portion 2 in the direction of the second rotation axis D2, and a support surface 63 is formed at its tip. The support surface 63 is the surface that is placed on the mounting surface B and is tilted at a predetermined angle with respect to the reference surface C.
[0056] Thus, in the infant spinning toy 1 according to this embodiment, a spinning part 3 is arranged on the base part 2 so as to be rotatable relative to the base part 2. Therefore, even infants who cannot roll over, infants who can roll over but cannot crawl, or infants who can crawl but cannot stand can easily reach the spinning part 3 and easily touch and spin the spinning part 3 with their own hands. This can stimulate the curiosity of infants.
[0057] Furthermore, in this infant spinning toy 1, the spinning part 3 is mounted on the base part 2, and the rotation axis A of the spinning part 3 extends in the direction on which the spinning part 3 is mounted relative to the base part 2. This allows the spinning part 3 to be positioned at a low height, and the spinning part 3 can be touched and rotated from any position around the rotation axis A. As a result, infants who cannot roll over, infants who can roll over but cannot crawl, and infants who can crawl but cannot stand can more easily reach the spinning part 3 and rotate it more easily.
[0058] Furthermore, in this infant spinning toy 1, the base portion 2 extends along the reference plane C, and the rotation axis A of the spinning portion 3 extends in a direction perpendicular to the reference plane C. This allows the spinning portion 3 to be positioned at a low height, and the spinning portion 3 can be touched and rotated from any position around the rotation axis A. As a result, infants who cannot roll over, infants who can roll over but cannot crawl, and infants who can crawl but cannot stand can more easily reach the spinning portion 3 and rotate it more easily.
[0059] Furthermore, in this infant spinning toy 1, the base portion 2 has an annular inner guide rail 22 and an outer guide rail 23 that guide the rotation of the spinning portion 3, so that the spinning portion 3 can be rotated stably.
[0060] Furthermore, in this infant spinning toy 1, the rotating part 3 is mounted on the inner guide rail 22 and the outer guide rail 23, allowing the rotating part 3 to rotate more stably.
[0061] Furthermore, in this infant spinning toy 1, the rotating part 3 is mounted on the inner guide rail 22 and the outer guide rail 23 via a bearing 4 positioned between the base part 2 and the rotating part 3. Therefore, even infants with weak strength can smoothly rotate the rotating part 3 relative to the base part 2 with minimal effort.
[0062] Furthermore, in this infant spinning toy 1, the spinning part 3 has a dome-shaped dome part 71, which makes it easier for infants to touch the spinning part 3 and prevents the spinning part 3 from hitting the infant's hand.
[0063] Furthermore, in this infant rotating toy 1, the dome portion 71 is transparent, allowing the inside of the rotating portion 3 to be seen through the dome portion 71. Therefore, for example, by putting objects inside the rotating portion 3 or drawing pictures inside, it is possible to strongly attract the interest of infants.
[0064] Furthermore, in this infant spinning toy 1, the dome portion 71 is formed hollow, and multiple lenses 74 are formed on the inner surface 71b of the dome portion 71, so that complex patterns and gloss can be projected onto the dome portion 71. Moreover, by rotating the spinning portion 3, the dome portion 71 can be made to sparkle. This can further stimulate the curiosity of infants.
[0065] Furthermore, in this infant spinning toy 1, a mirrored sheet 10 is placed in the hollow part 31 of the rotating part 3, which gives the dome part 71 a glossy appearance. Moreover, since multiple lenses 74 are formed on the inner surface 71b of the dome part 71, rotating the rotating part 3 makes the dome part 71 sparkle even more due to the reflected light from the mirrored sheet 10. This further stimulates the curiosity of infants.
[0066] Furthermore, in this infant spinning toy 1, the beads 11 are housed in the hollow part 31 of the rotating part 3. By rotating the rotating part 3, the beads 11 can be moved around freely, and the beads 11 can make sounds when they hit the rotating part 3, etc. This can further stimulate the curiosity of infants.
[0067] Furthermore, in this infant spinning toy 1, ribs 73 are formed on the outer surface 71a of the dome portion 71, extending in a direction intersecting the rotation direction E of the spinning portion 3. As a result, infants can easily rotate the spinning portion 3 by catching their hands on the ribs 73.
[0068] Furthermore, in this infant rotating toy 1, the decorative part 9 that protrudes from the outer surface 71a of the dome part 71 is attached to the dome part 71, thereby improving the aesthetic appeal of the dome part 71 and allowing the rotating part 3 to be rotated by touching the decorative part 9. Moreover, since the decorative part 9 penetrates the dome part 71 and is fixed to the dome part 71 on the inner surface 71b side of the dome part 71, the decorative part 9 can be fixed to the dome part 71 without degrading the aesthetic appeal of the outer surface 71a side of the dome part 71, and this fixing part can be prevented from coming into contact with the hands of infants.
[0069] Furthermore, in this infant spinning toy 1, the rotation axis A of the spinning part 3 can be tilted by attaching the stand 6 to the base part 2, so that even infants who have difficulty moving their hands up and down can easily rotate the spinning part 3. On the other hand, by removing the stand 6 from the base part 2, the spinning part 3 can be rotated stably, and the infant spinning toy 1 can be made smaller to improve storage.
[0070] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above.
[0071] For example, although the above embodiment was described as having a dome-shaped rotating part, the shape of the rotating part is not particularly limited and may be formed in a polygonal shape, or it may be formed in a shape that imitates the whole or a part of a character such as an animal.
[0072] Furthermore, although the above embodiment was described as having a rotation axis extending in the direction in which the rotation part is placed relative to the base, the rotation axis of the rotation part may extend in a direction inclined with respect to the direction in which the rotation part is placed relative to the base.
[0073] Furthermore, although the above embodiment was described as having a hollow dome shape, the dome shape may also be a solid dome shape. [Explanation of Symbols]
