Spinning top toy

Abstract

A spinning top toy including a body and a separate shaft portion. The body has a first hook and the shaft portion has a second hook. The body and the shaft portion are switchable between couplable and decouplable states depending on a relative rotational position. The first hook and the second hook are vertically aligned in the couplable state, and are vertically misaligned in the decouplable state. An urging unit brings an upper face of the first hook and a bottom face of the second hook into contact by an urging force of a spring in the couplable state. The body and the shaft portion enter the couplable state by turning and pushing. The body and the shaft portion engage each other by bringing the upper face of the first hook into contact with the bottom face of the second hook by the urging force of the spring.

(12) Detailed Configuration

(13) 1. Shaft Portion 10

(14) The shaft portion 10 includes a rotary shaft 11 at a lower portion 49 thereof, a flange 12 in a middle portion, and a cylinder 13 in an upper portion 48. The rotary shaft 11, the flange 12, and the cylinder 13 are composed of synthetic resin. Alternatively, any material other than synthetic resin may be selected; for example, one or more of the rotary shaft 11, the flange 12, and the cylinder 13 may be composed of metal.

(15) The lower portion of the flange 12 has a substantial shape of an inverted cone outlined by steps leading from the flange 12 to the outer circumference of the rotary shaft 11.

(16) With reference to FIG. 2, holes 14 are provided in the flange 12 and the cylinder 13 at two positions opposite to each other in the front and back direction across the axis of the rotary shaft 11. The cylinder 13 and the lower portions of flange 12 have first protrusions 15 at two positions opposite to each other in the left and right direction across the axis of the rotary shaft 11. The outer surfaces of the first protrusions 15 are flush with the outer circumferential surface of the flange 12.

(17) With reference to FIG. 3, a fixed inner segment, i.e., a column, 16 is vertically disposed inside the cylinder 13. The upper surface of the column 16 may be disposed at any position, for example, above the upper surface of the cylinder 13. An upper end 17a of the column 16 has first projections or hooks (first hooks) 17 (having flat lower surfaces 17b) projecting radially outward from two positions opposite to each other in the front and back direction across the axis of the rotary shaft 11.

(18) The shaft portion 10 includes a segment that is movable relative to the fixed inner segment or column 16 of the shaft portion 10, i.e., a movable cylindrical segment, 18 which is disposed inside the cylinder 13 and which surrounds the upper region of the outer circumference of the column 16. The lower region of the outer circumferential surface of the movable segment 18 has second projections 19 projecting radially outward from two positions opposite to each other in the front and back direction across the axis of the rotary shaft 11. With reference to FIG. 3, the second projections 19 fit into the holes 14. The movable segment 18 can move vertically, but the upward movement is restricted by the upper edges of the holes 14. The movable segment 18 is urged upward by a coil spring 20 wound around the column 16. Normally, the second projections 19 are in contact with the upper edges of the holes 14, and the upper surface of the movable segment 18 is flush with the upper end 17a of the cylinder 13.

(19) An upper surface 18a of the movable segment 18 has radially extending linear third projections 21 at two positions opposite to each other in the left and right direction across the axis of the rotary shaft 11.

(20) 2. Adjuster Ring 30

(21) According to this embodiment, the adjuster ring 30 is a fly wheel. This adjuster ring 30 is a plate ring. An annular step 31 is provided on a bottom surface 31a of the adjuster ring 30 for receiving the flange 12 of the shaft 10 inserted from below. An upper surface of the adjuster ring 30 has second protrusions 32 extending upward from two positions opposite to each other in the left and right direction across the axis of the rotary shaft 11. First depressions 33 are provided below the second protrusions 32 for receiving the first protrusions 15 of the shaft portion 10 inserted from below. The upper surface of the adjuster ring 30 has tongues 34 adjoining outer faces of the second protrusions 32 and extending upward. The tongues 34 protrude above the second protrusions 32.

(22) Instead of the body 40 described below, the adjuster ring 30 may be the one that has an uneven profile with protrusions on the outer circumferential surface for an effective attack on a spinning top toy 1 of an opponent or the one that has depressions on the outer circumferential surface for defense against an attack by a spinning top toy 1 of an opponent. Such protrusions or depressions may be integrated with the fly wheel.

(23) 3. Body 40

(24) The body 40 has a discoidal shape. With reference to FIG. 2, the body 40 includes a base 400 and a transparent cover 401 covering the base 400 and having a shape substantially identical to that of the base 400 in top view.

(25) Uneven profile 40a is formed on the outer circumference of the body 40. A circular hole 41 is provided at the center of the base 400. The circular hole 41 is covered with the transparent cover 401 from above. The bottom surface of the body 40 has an annular second depression 42 for receiving the second protrusions 32 of the adjuster ring 30 inserted from below.

(26) The inner circumferential wall 43a defining the annular depression 42 has fourth projections or hooks (second hooks) 44 (with flat upper surfaces 44a) at the bottom edge projecting radially inward from two positions opposite to each other in the front and back direction across the axis of the rotary shaft 11. The bottom edge of the inner circumferential wall 43a has radially extending linear first recesses 45 provided at a predetermined pitch along the circumference in two regions opposite to each other in the left and right direction across the axis of the rotary shaft 11.

(27) A ceiling 43b defining the second annular depression 42 of the body 40 has arcuate slits 46 through which the tongues 34 of the adjuster ring 30 are inserted from below. The arcuate slits 46 are long enough for the tongues 34 to move therein.

(28) Assembly

(29) An example of the assembly of the spinning top toy 1 will now be described.

(30) The first protrusions 15 of the shaft portion 10 are aligned to the first depressions 33 of the adjuster ring 30 from below, and the shaft portion 10 is fit to the adjuster ring 30. This assembly is aligned with the body 40 from below. The tongues 34 of the adjuster ring 30 of the assembly are aligned to predetermined ends of the arcuate slits 46 of the body 40 (FIG. 4A). In this state, the first projections 17 of the shaft portion 10 and the fourth projections 44 of the body 40 are not vertically aligned. This state is referred to as a decouplable state. Subsequently, the shaft portion 10 of the assembly is urged toward the body 40. As a result, the adjuster ring 30 is pushed against the bottom surface of the body 40. Urging of the shaft portion 10 of the assembly toward the body 40 causes the bottom surface of the adjuster ring 30 to push the second projections 19 of the shaft portion 10 downward in direction of C of FIG. 3 against the urging force of the coil spring 20. In this state, the first projections 17 of the shaft portion 10 are biased above the fourth projections 44 of the body 40. The shaft portion 10 is turned together with the adjuster ring 30 relative to the body 40 until the tongues 34 move to the ends opposite to the predetermined ends (FIG. 4B). The adjuster ring 30 and the shaft portion 10 are turned relative to the body 40. FIG. 4B illustrates the body 40 turned relative to the shaft portion 10 and the adjuster ring 30. This vertically aligns the first projections 17 of the shaft portion 10 and the second projections 44 of the body 40. This state is referred to as a couplable state. Releasing the hand of the user from the shaft portion 10 causes the flat lower surfaces 17 of the first projections 17 to come into contact with the flat upper surfaces 44a of the second projections 44 of the body 40 by the urging force of the coil spring 20, and the shaft portion 10, the adjuster ring 30, and the body 40 to couple to each other, so as to assemble the spinning top toy 1.

(31) How to Play

(32) An example of how to play with the spinning top toy 1 will now be described.

(33) In this example, a spinning top toy 1 engages in a battle with another spinning top toy 1.

(34) The rotational force of the spinning top toy 1 is generated with a launcher 50, such as that illustrated in FIG. 5. The launcher 50 includes an internal disk (not shown). The disk is urged in a first rotational direction by a spiral spring (not shown). A handle 51 is then pulled to pull a string (not shown) wound around the disk so as to spin the disk, thereby spinning a top holder 53. The spinning of the top holder 53 is transmitted to the spinning top toy 1 through forks 54 protruding downward so as to spin the spinning top toy 1. The forks 54 are inserted into the arcuate slits 46 of the body 40. Fully pulling the handle 51 of the launcher 50 stops the spinning of the disk and thus the spinning of the top holder 53, but the spinning top toy 1 continues to spin due to inertia. The spinning top toy 1 follows the tilting faces 54a of the forks 54, respectively, and detaches from the top holder 53. In FIG. 5, reference numeral 52 denotes a rod that can hide in the top holder 53. When the spinning top toy 1 is mounted on the top holder 53, the rod 52 is pushed into the top holder 53 by the upper surface of the spinning top toy 1. The rod 52 detects the attachment or detachment of the spinning top toy 1, for example.

(35) The spinning top toy 1 launched in this way spins in a predetermined field and collides with another spinning top toy 1 of an opponent. The impact force and friction generated by the collision generate a reactive force at the body 40 in a direction opposite to the rotational direction of the shaft portion 10 (in direction B shown in FIG. 3) and the adjuster ring 30, as illustrated in FIG. 4B. This causes the body 40 to spin in an opposite direction relative to the rotational direction of the shaft portion 10 and the adjuster ring 30.

(36) This spinning causes each of the linear first recesses 45 of the body 40 to engage the corresponding linear third projections 21 of the shaft portion 10 one by one for positioning. At the position illustrated in FIG. 4A, the fourth projections 44 of the body 40 detach from the first projections 17 of the shaft portion 10, and the body 40 moves away from the shaft portion 10 by the urging force of the coil spring 20. This dissembles the spinning top toy 1 as illustrated in the right of FIG. 1.

MODIFICATIONS OF EMBODIMENT OF PRESENT INVENTION

(37) The present invention should not be limited to the embodiment described above and may be modified in various ways without departing from the scope of the invention.

(38) In the embodiment described above, the linear third projections 21 of the shaft portion 10 and the linear third depressions 45 of the body 40 are provided as rotation resistors between the shaft portion 10 and the body 40. Alternatively, for example, projections and depressions, respectively, having other shapes may be provided. The number of projections and depressions should not be limited to that according to the embodiment described above. The rotation resistors may be composed of rubber and disposed on the opposing surfaces of the shaft portion 10 and the body 40, for example. In such a case, the shaft portion 10 and the body 40 spin relative to each other by an external impact force so as to gradually disengage from each other.

(39) In the embodiment described above, the spinning top toy 1 spins clockwise in top view. Alternatively, the spinning top toy 1 may spin counterclockwise in top view. In such a case, the shaft portion 10 and the adjuster ring 30 which are the same as above can be used while the body 40 is replaced with a different one so as to readily assemble a spinning top toy 1 in which the body 40 spins counterclockwise in top view relative to the shaft portion 10 and the adjuster ring 30.

(40) In the embodiment described above, a battle game involving spinning top toys 1 and 1 that spin clockwise in top view is described. Alternatively, the battle game may involve spinning top toys 1 and 1 that spin counterclockwise in top view.

(41) Alternatively, the battle game may involve a spinning top toy 1 that spins clockwise in top view and another spinning top toy 1 that spins counterclockwise in top view.

(42) In such a case, the body 40 turns relative to the shaft portion 10 from the decouplable state to the couplable state due to the collision force and friction of the spinning top toys 1 and 1. In other words, the shaft portion 10 and the body 40 turn to firmly engage with each other. Thus, the spinning top toy 1 cannot be readily disassembled by a collision force or friction in some cases. In such a case, the win or loss of the game can be based on knocking out of the spinning top toy 1 of the opponent. It should be noted that the battle game can involve three or more spinning top toys 1.

(43) The present invention can be suitably applied to manufacturing of spinning top toys.
