Description

Technical Field

[0001] This invention relates to a hand-spinning top. Background Technology

[0002] Previously, there was a known hand-spinning top that included a grip and a spinning top that could be rotated around the grip by a user (Patent Document 1).

[0003] Patent Document 1: Japanese Utility Model Registration No. 3212430.

[0004] Users can enjoy the movement of the hand-spinning top when touched, but visually, it's merely a change in the pattern on the blades of the top as it rotates. The purpose of this invention is to provide a more interesting hand-spinning top by adding a clever structure. Summary of the Invention

[0005] The first technical solution of the present invention provides a hand-spinning top, comprising a gripping part and a spinning top part that can be rotated around the gripping part by the user. The hand-spinning top is provided with a mirror component, which is positioned so that the user can observe it during use. The user can make the hand-spinning top move by touching it and can observe the image reflected in the mirror component. The gripping part is provided with a suction cup for fixing the gripping part to a plane.

[0006] The second technical solution is based on the first technical solution, wherein the central part of the upper surface of the hand-held gyroscope protrudes in a dome shape relative to the peripheral part surrounding the central part.

[0007] The third technical solution is based on the first technical solution, in which the mirror component is covered by a transparent cover.

[0008] The fourth technical solution is based on the second technical solution, with the mirror component provided in the central part.

[0009] The fifth technical solution is based on the fourth technical solution, with visual decoration provided on the upper surface of the gyroscope part.

[0010] The sixth technical solution is based on the fifth technical solution, in which the mirror component can reflect the visual decoration.

[0011] The seventh technical solution is based on the sixth technical solution, in which the gyroscope part is connected to the gripping part via a bearing.

[0012] The eighth technical solution is based on the seventh technical solution, wherein the gyroscope is composed of a rotating base and multiple blades; the rotating base is fixed to the outer ring of the bearing; and the multiple blades are arranged at predetermined intervals along the circumference of the rotating base.

[0013] The ninth technical solution is based on the eighth technical solution, in which each of the multiple blades is individually provided with visual decorations that are different from the other blades, thus forming a structure in which each blade can be distinguished and identified visually.

[0014] The tenth technical solution is based on any one of the fifth to ninth technical solutions, wherein the central part and the visual decoration are covered by a transparent cover.

[0015] The eleventh technical solution is based on the eighth or ninth technical solution, in which each of the multiple blades is individually provided with engraved patterns, and the engraved patterns have a different tactile feel from the other blades.

[0016] According to the present invention, the user can enjoy the motion of the hand-spinning top when touched, and can also observe the image (mirror image) reflected by the mirror component, thereby realizing a highly interesting hand-spinning top. Attached Figure Description

[0018] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0019] Figure 1 This is a perspective view of the hand-spinning top 100 according to this embodiment in use. Figure 2This is a front view of the hand-spinning top 100. The hand-spinning top 100 of this embodiment includes a handle 10 and a spinning top 50 capable of rotating around the handle 10. In use, the handle 10 is fixed to a flat surface such as a floor, table, or high chair tray using suction cups 11. It can also be fixed to a bathroom or wall as long as it is a flat surface. When fixed, the user can tap, push, or hook the spinning top 50 with their fingers to make it rotate. Thus, by touching the hand-spinning top 100, the user (mainly young children) can feel the tactile sensation from their fingers, experience the tilting and rotating motions of the spinning top 100, and observe the visual changes in the patterns on the spinning top 50 as it rotates. Additionally, the user can observe the changes in the image reflected by the mirror component of the hand-spinning top 100.

[0020] "overall" Figure 3 This is a top-view perspective view of the disassembled grip section 10 and top section 50 of the hand-spinning top 100. Figure 4 This is a perspective view below. As shown in these figures, the grip 10 is located on the lower center of the gyroscope 50.

[0021] (Gyroscope Section 50) Figure 5 This is a top perspective view of the exploded gyroscope section 50. The gyroscope section 50 includes a gyroscope body 51, a mirror component 52 disposed on the gyroscope body 51, and a transparent cover 53.

[0022] The gyroscope body 51 has a centrally located rotating base 51a and four blades 51b disposed on the rotating base 51a.

[0023] A cylindrical bearing support portion 51c is formed at the center of the upper surface of the rotating base 51a. The bearing support portion 51c has a shape that can accommodate the bearing 60 internally; an inwardly projecting flange 51d is integrally formed at the lower end of the bearing support portion 51c. The inwardly projecting flange 51d serves as a support structure to prevent the bearing 60 from falling off, and also serves to form an opening for the shaft 14b (inner race) that engages with the inner race (inner race) of the bearing 60. Figure 3 The bearing support 51c is configured to be fixed relative to the outer ring (outer race) of the bearing 60, ensuring axial and radial positional stability while maintaining the rotational function of the bearing 60. Figure 5 In the attached figure, reference numeral 51e indicates a retaining ring, which is fitted into the upper end of shaft 14b.

[0024] Furthermore, on the outer side of the bearing support portion 51c on the rotating base 51a, with the bearing support portion 51c positioned in the middle, a pair of internally threaded bosses 51f protrude upwards from the upper surface of the rotating base 51a. These bosses 51f are screwed onto a crimping member 51g for retaining the bearing 60, by which the bearing 60 is axially fixed. Through this structure, the bearing 60 housed within the bearing support portion 51c is reliably held, and a support structure is formed integrally with the rotating base 51a.

[0025] An annular groove 51h is formed on the upper surface of the rotating base 51a, radially outward of the boss 51f. The mirror member 52 is seated in the annular groove 51h.

[0026] Four blades 51b are formed on the radially outer side of the rotating base 51a. The four blades 51b are identical in shape and are arranged at equal intervals along the circumference. Each blade 51b is decorated with a pattern (visual decoration, such as a character pattern), and the lower end of the pattern is positioned towards the center of the rotating base 51a (see reference). Figure 1 That is, when viewed from the radially outer side of the blade 51b, the pattern appears inverted. Furthermore, although four blades 51b are formed here, the number of blades 51b can be any number from one to three, or even five or more. Moreover, when multiple blades 51b are formed, their shapes can be different from each other.

[0027] The mirror component 52 has a dome-shaped overall shape, consisting of a cylindrical portion 52a erected on the rotating base 51a and a hemispherical head 52b connected to the upper end of the cylindrical portion 52a. The outer surface of the mirror component 52 is mirror-finished; the mirror component 52 is mounted on the rotating base 51a by inserting the cylindrical portion 52a into the annular groove 51h. With this structure, the mirror component 52 rotates integrally with the gyroscope body 51. According to this mirror component 52, when in use, the mirror surface of the cylindrical portion 52a reflects the pattern attached to the blades 51b, and the mirror surface of the head 52b reflects the user's own face and its background. At this time, the pattern of the blades 51b reflected on the mirror surface of the cylindrical portion 52a becomes an upright image at the cylindrical portion 52a; the image (the user's own face, etc.) reflected on the mirror surface of the head 52b is upright and reduced in size.

[0028] The mirror component 52 is made of plastic or metal, and the surface is processed by vapor deposition, sputtering or electroplating. If the mirror component 52 is made of plastic and mirror processing is performed by electroplating, then metal electroplating is performed after the plastic surface is made conductive.

[0029] The transparent cover 53 is made of transparent plastic and has a shape that can cover the upper surface of the gyroscope body 51, including the mirror member 52. The transparent cover 53 is fitted with the blade 51b and the mirror member 52; in the fitted state, the lower end of the transparent cover 53 is placed on the step portion 51i at the lower end of the blade 51b.

[0030] In addition, such as Figure 3 as well as Figure 4 As shown, engravings (recesses and / or protrusions) 51j are added to the sides of the portion of the blade 51b covered by the transparent cover 53 and to the lower surface of the blade 51b, so that the tactile feel of each blade is different. With this structure, when the user touches the blade 51b, he / she can enjoy the tactile feel and the tactile differences between each blade.

[0031] (Control Section 10) Figure 6 This is a three-dimensional view of the disassembled holding part 10. Figure 7 This is a perspective view of a portion of the gripping part 10 after being disassembled. The gripping part 10 includes a suction cup 11 with an adsorption function, a suction cup mounting part 12 for mounting the suction cup 11, a suction cup fixing rod 13 for mounting the suction cup 11 to the suction cup mounting part 12, and a shaft base 14 mounted above the suction cup mounting part 12.

[0032] The suction cup 11 has a hole 11a in its rod portion 11b. With the rod portion 11b of the suction cup 11 inserted into the insertion hole 12a of the suction cup mounting portion 12, the suction cup fixing rod 13 is inserted into the hole 11a, thereby mounting the suction cup 11 to the suction cup mounting portion 12. A protrusion 11d is formed on the upper surface of the cup-shaped portion 11c of the suction cup 11. Accordingly, the suction cup 11 is configured such that when the protrusion on the upper surface of the cup-shaped portion 11c is pressed with a finger, air is introduced to the lower side of the cup-shaped portion 11c, allowing it to be easily detached from the suction surface. Alternatively, depending on the size of the protrusion 11d, the protrusion 11d can be pinched to introduce air into the lower side of the cup-shaped portion 11c.

[0033] The shaft base 14 has four countersunk holes 14a, through which the external threads (not shown) of the countersunk holes 14a are threaded to the suction cup mounting part 12. The shaft base 14 has an upright shaft 14b, which is inserted from below through the opening of the bearing support part 51c and fixed to the inner ring of the bearing 60.

[0034] In addition, the suction cup mounting part 12 and the shaft base 14 are fitted from the inside into the cylinder 51k formed on the lower surface of the rotating base 51a.

[0035] Effects of the Implementation Method The hand-spinning top 100 according to this embodiment can achieve the following effects: Users can derive pleasure and satisfaction from observing the movement of the gyroscope 50. Furthermore, during operation, the tactile feedback, such as the rotational resistance and changes in inertia felt by the fingertips, allows for a better experience of the operating feel; Furthermore, the patterns and designs on the surface of the gyroscope 50 change visually as it rotates, enhancing the overall experience, including the visual effects during the motion.

[0036] Furthermore, the bottom of the mirror reflects patterns that move and change as the gyroscope 50 rotates, while the top of the mirror reflects the child's own face and the surrounding scenery. This simultaneous observation of moving and stationary objects creates a sense of visual incongruity and surprise, particularly appealing to young children, and effectively draws their attention to the mirror.

[0037] Variations The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and can be modified in various ways.

[0038] In the above embodiment, the protrusion at the center of the hand-held spinning top 100 is formed by a portion of the spinning top portion 50, but this protrusion may also be formed by a portion of the grip portion 10. Alternatively, this protrusion may be formed by both a portion of the spinning top portion 50 and a portion of the grip portion 10. The condition that must be met is that the image reflected by the mirror falls within the user's field of vision and is in a state that can be observed.

[0039] In addition, in the above embodiments, the mirror surface can be provided on the protrusion or on the blade 51b. Alternatively, the mirror surface can be provided on the protrusion or a portion of the blade 51b.

[0040] In addition, while the suction cup 11 is used to fix the hand-twisted gyroscope 100 in the above embodiment, magnets, adhesive tape, clips or Velcro can also be used as alternatives.

[0041] Furthermore, in the above embodiments, from an operability perspective, the rotating base 51a and the blade 51b are preferably formed of a hard material such as hard plastic, but they may also be formed of a soft material such as rubber.

[0042] In addition to direct printing, visual decorations can also be added using techniques such as pad printing. Examples of additional visual decorations include shapes, patterns, colors, or combinations of these elements. In this case, there are no particular limitations on adding color as a visual decoration, but it is preferable to assign each leaf 51b a different color.

[0043] Furthermore, although the number of blades 51b is not limited in the above embodiments, for example, the number of blades 51b can be set to two. The two blades 51b are formed on the protrusion in directions away from each other, and the protrusion and the two blades are set as rounded squares in a top view to simulate the shape of a toy car body. Wheel-shaped carvings can also be provided on both sides of the two blades. In this case, the protrusion can be a rounded square in a top view, but the upper surface is preferably dome-shaped.
