Description

[Technical Field]

[0001] The present disclosure relates to a coin spinning device, and more particularly to a coin spinning device used to spin a coin like a top. [Background technology]

[0002] People can spin a coin like a top, either for the fun of it or to guess which side will be facing up when the coin stops. Other games involve writing letters such as YES and NO on the front and back of a coin, and then acting according to the letter that appears on the top of the coin when it stops. Summary of the Invention [Problem to be solved by the invention]

[0003] A certain level of skill is required to spin the coin like a top and keep it spinning for a long time, and if you fail to spin the coin properly, it may roll to an unexpected place.

[0004] An object of the present disclosure is to provide a coin spinning device that can easily spin a coin like a top. [Means for solving the problem]

[0005] A coin spinning device according to one aspect of the present disclosure has a front end and a rear end. The coin spinning device includes a main body, an action portion, a spring portion, a stopper portion, and an operating portion. The main body is cylindrical along the direction in which the front end and the rear end are aligned, and has an opening at the end on the front end side. The action portion includes a shaft portion along the direction, and a holding portion extending from the end on the front end side of the shaft portion and configured to hold the coin by clamping its outer periphery. The shaft portion is inserted into the main body, and the holding portion protrudes from the opening to the outside of the main body. The action portion is axially rotatable relative to the main body. The spring portion applies an elastic force to the action portion, causing it to rotate axially relative to the main body. The stopper portion restricts the axial rotation of the action portion relative to the main body. The operating portion releases the restriction imposed by the stopper portion in response to an external operation. [Effects of the Invention]

[0006] According to the present disclosure, when a coin is held in the holding portion of the coin spinning device, the user can release the restriction imposed by the stopper portion by operating the operating portion, thereby causing the coin to spin and drop out of the holding portion, thereby allowing the coin to spin like a top.

[0008] The following embodiments and modifications will be described with reference to Figs. 1 to 5. The following embodiments and modifications are merely a portion of the various embodiments of the present disclosure. The following embodiments and modifications can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. The configurations of the modifications can also be combined as appropriate.

[0009] The drawings referred to below are all schematic drawings, and the dimensional ratios of the components in the drawings do not necessarily reflect the actual dimensional ratios.

[0010] 2.Details Hereinafter, a first embodiment and a second embodiment of the present disclosure will be described.

[0011] (1) First embodiment A coil winding tool according to a first embodiment will be described with reference to FIGS. 1A to 2. FIG.

[0012] In the first embodiment, the coin spinning device 1 has a leading end 11 and a trailing end 12. Hereinafter, the direction in which the leading end 11 and the trailing end 12 are aligned will be referred to as the axial direction, and the leading end 11 side means the leading end 11 side of the coin spinning device 1 in the axial direction, and the trailing end 12 side means the trailing end 12 side of the coin spinning device 1 in the axial direction.

[0013] The coin spinning device 1 comprises a main body 2, an action part 3, a spring part 4, a stopper part 5, and an operation part 6, and the stopper part 5 comprises a meshing part 51 and a meshing part 52.

[0014] The main body 2 is cylindrical and elongated in the axial direction. The main body 2 is composed of a cylindrical peripheral wall 21. The main body 2 has an opening (first opening 22) at the end on the tip 11 side and also has an opening (second opening 23) at the end on the rear end 12 side. The end of the main body 2 on the tip 11 side has a locking portion 52 that constitutes the stopper portion 5. The locking portion 52 is located on the edge of the first opening 22 and consists of two recesses 520 formed in the peripheral wall 21. Each recess 520 connects the inside and outside of the peripheral wall 21 and is open toward the tip 11 side. The two recesses 520 face each other in a direction perpendicular to the axial direction, sandwiching the first opening 22 therebetween. The main body 2 is made of a material such as a resin material or metal.

[0015] The action part 3 has a shaft part 31 and a holding part 32. The shaft part 31 is rod-shaped and long in the axial direction. The material of the shaft part 31 is, for example, a resin material or a metal. The shaft part 31 is inserted into the main body part 2, and the end part of the shaft part 31 on the rear end 12 side protrudes from the second opening 23 of the main body part 2 toward the rear end 12 side.

[0016] The holding portion 32 extends from the end of the shaft portion 31 on the tip 11 side toward the tip 11 and protrudes from the first opening 22 to the outside of the main body portion 2. The material of the holding portion 32 is, for example, a resin material or a metal. In the first embodiment, the holding portion 32 is a separate member from the shaft portion 31 and is fixed to the end of the shaft portion 31 on the tip 11 side. The holding portion 32 has two clamping pieces 321. The end of each clamping piece 321 on the rear end 12 side is fixed to the end of the shaft portion 31 on the tip 11 side. The two clamping pieces 321 face each other in a direction perpendicular to the axial direction. The clamping pieces 321 are curved in an arc so as to bulge outward from each other. The maximum distance between the two clamping pieces 321 is longer than the diameter of the coin 7 held by the holding portion 32. In other words, the holding portion 32 holds coins 7 having a diameter shorter than the maximum distance between the two clamping pieces 321.

[0017] Two cover portions 322 are fixed to each clamping piece 321. That is, the holding unit 32 has four cover portions 322. In each clamping piece 321, the two cover portions 322 face each other at an interval in a direction perpendicular to both the axial direction and the direction in which the two clamping pieces 321 face each other, and the clamping piece 321 is sandwiched between the two cover portions 322 and is arranged so that one clamping piece 321 protrudes from the clamping piece 321 to which it is fixed toward the other clamping piece 321.

[0018] The action part 3 is axially rotatable relative to the main body part 2 and is also axially movable.

[0019] An interlocking portion 51 constituting the stopper portion 5 is fixed to the end of the working portion 3 on the tip 11 side of the shaft portion 31. The interlocking portion 51 is rod-shaped and long in a direction perpendicular to the axial direction, and the two ends of the interlocking portion 51 protrude from the end of the shaft portion 31 in opposite directions in a direction perpendicular to the axial direction.

[0020] The meshing portion 51 and the meshing portion 52 constitute the stopper portion 5. That is, the stopper portion 5 includes the meshing portion 51 and the meshing portion 52. The meshing portion 51 is disposed on the tip 11 side of the meshing portion 52, and moves axially relative to the meshing portion 52 as the operating portion 3 moves axially. When the meshing portion 51 abuts against the meshing portion 52 from the tip 11 side, the two ends of the meshing portion 51 fit into two recesses 520 in the meshing portion 52, respectively, and the stopper portion 5 enters an meshed state in which the meshing portion 51 and the meshing portion 52 mesh with each other. In this meshed state, the stopper portion 5 restricts the axial rotation of the operating portion 3 relative to the main body portion 2. When the stopper portion 5 is in an engaged state, when the acting portion 3 moves toward the axial tip 11, the engaging portion 51 moves toward the tip 11 relative to the engaging portion 52, and the engaged state is released, i.e., the restriction by the stopper portion 5 is released, and the acting portion 3 becomes able to rotate axially relative to the main body portion 2.

[0021] The spring portion 4 is a coil spring. The coil spring is arranged within the main body portion 2 so as to surround the shaft portion 31 of the action portion 3. The end portion of the coil spring on the rear end 12 side is fixed by being hooked onto the end portion of the main body portion 2 on the rear end 12 side. The end portion of the coil spring on the front end 11 side is fixed to the portion of the shaft portion 31 of the action portion 3 on the front end 11 side. Therefore, when the action portion 3 is rotated axially relative to the main body portion 2, an elastic force is generated in the spring portion 4 that tries to rotate the action portion 3 axially in a direction opposite to the axial rotation.

[0022] The inner diameter of the coil spring is larger than the outer diameter of the shaft portion 31. Furthermore, the inner diameter of the coil spring is adjusted so that it matches the outer diameter of the shaft portion 31 when the acting portion 3 is rotated around its axis an appropriate number of times relative to the main body portion 2 so as to squeeze the coil spring. This limits the number of axial rotations of the acting portion 3, preventing the acting portion 3 from rotating around its axis excessively. For example, the inner diameter of the coil spring and the outer diameter of the shaft portion 31 are adjusted so that the number of axial rotations of the acting portion 3 is limited to 4.5 rotations.

[0023] The main body 2 has a locking portion 24 that protrudes from the inner surface of the peripheral wall 21. The locking portion 24 is located below the spring portion 4. When the spring portion 4 attempts to move toward the tip 11, the end of the spring portion 4 on the tip 11 side hits the locking portion 24, thereby restricting the movement of the spring portion 4 toward the tip 11. Because the spring portion 4 is fixed to the action portion 3, the movement of the action portion 3 toward the tip 11 side is also restricted. This prevents the action portion 3 from coming off the main body 2.

[0024] The operation unit 6 includes a lid portion 61 and a pushing portion 62. The lid portion 61 is cylindrical and has a bottom that is open toward the tip 11. A hole 63 that axially penetrates the lid portion 61 is formed in the bottom of the lid portion 61. The pushing portion 62 is cylindrical and has a bottom that is open toward the tip 11. The pushing portion 62 is attached to the lid portion 61 so as to pass through the hole 63 of the lid portion 61 and is axially movable relative to the lid portion 61. The lid portion 61 is attached to the end portion on the rear end 12 side of the main body 2 so as to close the second opening 23. The end portion on the rear end 12 side of the shaft portion 31 of the operating unit 3 is inserted into the pushing portion 62, and the end portion on the rear end 12 side of the shaft portion 31 is fixed to the pushing portion 62. Therefore, when a user pushes the pushing portion 62 toward the tip 11 side, the pushing portion 62 moves toward the tip 11 side, and the operating unit 3 moves toward the tip 11 side accordingly. The operating portion 6 receives an external operation to release the restriction imposed by the stopper portion 5. That is, when the stopper portion 5 is in the meshed state, if the pushing portion 62 is pushed toward the tip 11 by an external operation, the action portion 3 moves toward the tip 11 as the pushing portion 62 moves, and as a result, the meshing portion 51 moves toward the tip 11 relative to the engaging portion 52, thereby releasing the meshed state.

[0025] When the stopper portion 5 is in the meshed state, the portions of the two clamping pieces 321 on the rear end 12 side are pushed into the main body portion 2 through the first opening 22, and a force is applied to the two clamping pieces 321 from the edge of the first opening 22 in a direction that brings them closer to each other. This narrows the maximum distance between the two clamping pieces 321. When the acting portion 3 moves axially toward the tip end 11 relative to the main body portion 2 and the meshed state is released, force is no longer applied to the two clamping pieces 321 from the edge of the first opening 22, and the distance between the two clamping pieces 321 widens and returns to its original position.

[0026] When a user spins a coin 7 using the coin spinning device 1, the user first places the coin 7 between the two clamping pieces 321 of the holder 32 in the disengaged state. The coin 7 is positioned so that it is sandwiched between the two cover parts 322 fixed to each clamping piece 321. In this state, the user rotates the operating part 3 about its axis relative to the main body 2, causing the spring part 4 to generate an elastic force that tends to rotate the operating part 3 about its axis in the direction opposite to the axial rotation. In this state, the user moves the operating part 3 toward the rear end 12 relative to the main body 2, bringing the stopper part 5 into an engaged state, and the stopper part 5 restricts the axial rotation of the operating part 3 relative to the main body 2. In this engaged state, a force is applied to the two clamping pieces 321 from the edges of the first opening 22, narrowing the gap between the two clamping pieces 321, thereby clamping the coin 7 between the two clamping pieces 321. At this time, the coin 7 is sandwiched between the two cover parts 322 fixed to each of the clamping pieces 321, and is thus stably held.

[0027] Next, the user holds coin spinning device 1 over any upward-facing surface (target surface), such as the ground, floor, or tabletop, with leading end 11 facing downward and trailing end 12 facing upward. In this state, the user operates operating unit 6. Specifically, the user presses pushing unit 62 of operating unit 6 to move it axially toward leading end 11, disengaging the meshed state and releasing the restriction imposed by stopper unit 5. This causes operating unit 3 to rotate about its axis due to the elastic force applied by spring unit 4, causing coin 7 to rotate as well. Furthermore, the force applied to clamping pieces 321 from the edge of first opening 22 of main body 2 is released, widening the gap between clamping pieces 321, causing coin 7 to drop from holding unit 32. Coin 7 that has dropped from holding unit 32 falls toward the target surface while rotating, spinning like a top on the target surface.

[0028] In this way, the user can use the coin spinner 1 to spin the coin 7 on the target surface like a top.

[0029] (2) Second embodiment A coin spinning device 1 of the second embodiment will be described with reference to Figures 3 to 5. The coin spinning device 1 of the second embodiment has the same configuration as the first embodiment except for the configuration of the meshing portion 51 and the meshing portion 52 of the stopper portion 5. In the following, the same components as those of the first embodiment are denoted by the same reference numerals in the drawings, and descriptions thereof will be omitted where appropriate.

[0030] The meshing portion 51 has a disk-shaped base 511 having an axial thickness, and a plurality of protrusions 512. The base 511 has a hole 513 formed therein that penetrates the base 511 in the axial direction. The plurality of protrusions 512 are arranged along the outer periphery of the base 511 so as to surround the center of the base 511. Each of the protrusions 512 protrudes from the base 511 toward the rear end 12 in the axial direction. The shaft portion 31 of the operating unit 3 is passed through the hole 513 of the meshing portion 51, and in this state, the meshing portion 51 is fixed to the shaft portion 31. The meshing portion 51 is arranged at a position closer to the rear end 12 than the spring portion 4.

[0031] The engaging portion 52 has a disk-shaped base portion 521 having an axial thickness, and a cylindrical portion 526. The base portion 521 has a hole 523 formed therein that penetrates the base portion 521 in the axial direction. The cylindrical portion 526 is cylindrical and protrudes from the outer periphery of the base portion 521 toward the tip 11. The cylindrical portion 526 has a plurality of recesses 522, the same number as the protrusions 512. Each recess 522 is a notch-like portion that is open toward the tip 11, and the plurality of recesses 522 are arranged along the outer periphery of the base portion 521 so as to surround the center of the base portion 521. Each recess 522 has a shape that matches the shape of the protrusions 512.

[0032] The interlocking portion 52 is fixed to the main body 2 at a position inside the main body 2, below the spring portion 4 and above the interlocking portion 51. The interlocking portion 52 has two screw holes 524 that open to the outer surface, and the peripheral wall 21 of the main body 2 has through holes 25 that respectively correspond to the two screw holes 524. The interlocking portion 52 is fixed to the main body 2 by passing a screw 525 through the through hole 25 and screwing it into the screw hole 524.

[0033] When a user spins a coin 7 using the coin spinning device 1, the user first places the coin 7 between the two clamping pieces 321, as in the first embodiment, and then rotates the operating unit 3 about its axis relative to the main body 2, thereby generating an elastic force in the spring 4 that rotates the operating unit 3 about its axis in the opposite direction to the axial rotation. In this state, the user moves the operating unit 3 toward the rear end 12 relative to the main body 2, and the multiple protrusions 512 of the interlocking unit 51 fit into the multiple recesses 522 of the interlocking unit 52 (see FIGS. 4A, 4B, and 5). As a result, the interlocking unit 51 abuts against the interlocking unit 52 from the front end 11, and the interlocking unit 51 and the interlocking unit 52 interlock, thereby bringing the stopper 5 into an interlocked state. This interlocked state restricts the axial rotation of the operating unit 3 relative to the main body 2. In this interlocked state, a force is applied to the two clamping pieces 321 from the edge of the first opening 22, narrowing the gap between the two clamping pieces 321 and clamping the coin 7 between the two clamping pieces 321. Since the coin 7 is clamped between the two cover parts 322 fixed to each clamping piece 321, the coin 7 is held stably.

[0034] As in the first embodiment, the user places the coin spinning device 1 above the target surface and operates the operating part 6 to release the interlocking state, thereby causing the coin 7 to spin like a top on the target surface.

[0035] (3) Variations In the first and second embodiments, the shaft portion 31 and the holding portion 32 are separate members, and the holding portion 32 is fixed to the shaft portion 31, but the shaft portion 31 and the holding portion 32 may be integrally molded. In this case, the action portion 3 may be a single member. In this case, the material of the action portion 3 is, for example, a metal or a resin material.

[0036] In the first and second embodiments, when the stopper portion is in the meshed state, force is applied to the two clamping pieces 321 from the edge of the first opening 22, thereby holding the coin 7 in the holder 32. However, the coin 7 may also be held by elastic force applied by the two clamping pieces 321. In this case, for example, the maximum distance between the two clamping pieces 321 is formed to be smaller than the diameter of the coin 7, and when the coin 7 is placed between the two clamping pieces 321, the two clamping pieces 321 deform and widen the gap. This generates elastic force in each of the two clamping pieces 321, and the coin 7 can be held by this elastic force. Furthermore, in this case, when the meshed state is released, the gap between the two clamping pieces 321 widens due to the impact and centrifugal force generated by the rotation of the holder 32, which may cause the coin 7 to fall out of the holder 32.

[0037] Furthermore, although the holding portion 32 includes the cover portion 322 in the embodiment, it is not necessary to include the cover portion 322. In this case, for example, a groove into which the outer periphery of the coin 7 is fitted may be formed in each clamping piece 321. In this case, when the coin 7 is clamped by the clamping pieces 321, the outer periphery of the coin 7 fits into the groove, so that the coin 7 can be held stably.

[0038] Furthermore, the configuration of the stopper portion 5 is not limited to the first and second embodiments. The configuration of the meshing portion 51 and the locking portion 52 may be any configuration as long as the axial rotation of the acting portion 3 relative to the main body portion 2 is restricted in the meshed state. Furthermore, the stopper portion 5 may be any configuration other than the mode including the meshing portion 51 and the locking portion 52 as long as it restricts the axial rotation of the acting portion 3 relative to the main body portion 2 and the restriction is released by operating the operating portion 6. The operating portion 6 may also have an appropriate structure according to the configuration of the stopper portion 5.

[0039] The spring portion 4 is also a coil spring in the first and second embodiments, but may be any spring as long as it can apply an elastic force to the action portion 3 to rotate it about its axis.

[0040] 3. Aspects As shown in the above embodiments and modifications, the present disclosure includes the following aspects.

[0041] The coin spinning device (1) of the first embodiment has a leading end (11) and a trailing end (12) in the axial direction. The coin spinning device (1) includes a main body (2), an action portion (3), a spring portion (4), a stopper portion (5), and an operating portion (6). The main body (2) is cylindrical along the axial direction and has a first opening (22) at its end on the leading end (11) side. The action portion (3) has a shaft portion (31) along the axial direction and a holding portion (32) extending from the end on the leading end (11) side of the shaft portion (31) and configured to hold the coin (7) by clamping its outer periphery. The shaft portion (31) is inserted into the main body (2), and the holding portion (32) protrudes from the first opening (22) to the outside of the main body (2). The action portion (3) is axially rotatable relative to the main body (2). The spring portion (4) applies an elastic force to the action portion (3) to rotate it about its axis relative to the main body portion (2). The stopper portion (5) restricts the axis rotation of the action portion (3) about its axis relative to the main body portion (2). The operating portion (6) receives an external operation and releases the restriction imposed by the stopper portion (5).

[0042] According to this embodiment, when a coin (7) is held in the holding portion (32) of the coin spinning device (1) and the stopper portion (5) restricts the axial rotation of the operating portion (3), the user can release the restriction imposed by the stopper portion (5) by operating the operating portion (6), thereby rotating the coin (7) and causing it to drop out of the holding portion (32). This allows the coin (7) to spin like a top.

[0043] In the second aspect, the operating portion (3) of the first aspect is movable in the axial direction of the coin spinning device (1) relative to the main body (2). The stopper portion (5) includes an interlocking portion (51) of the operating portion (3) and an interlocking portion (52) of the main body (2). The stopper portion (5) is configured to restrict the axial rotation of the operating portion (3) in an interlocked state where the interlocking portion (51) abuts against the interlocking portion (52) from the tip (11) side and the interlocking portion (51) and the interlocking portion (52) interlock, and to release the restriction on the axial rotation of the operating portion (3) when the interlocking portion (52) moves from the interlocked state toward the tip (11) side and the interlocked state is released. The operating portion (6) is configured to move the operating portion (3) toward the tip (11) relative to the main body (2) in the interlocked state in response to an external operation.
