Description

TECHNICAL FIELD

This document relates to skill toys.

BACKGROUND

Many toys employ two objects joined by a string, in which one object is used to catch the other. These include the Kendama or ring and pin, the classic ball and cup, the stick and ball, the balero, mountain bolo, diabolo, and various juggling toys. The Kendama is popular in Japan, and may commonly be found in various forms worldwide. The Kendama is made of two objects: a ball, and a grip held by the hand with a spiked end called a sword. The ball and the grip are connected by a string. A hole is drilled partially through the ball for spearing the ball on the spiked end. Two or more concave cups are placed on either side of the spike, one generally larger than the other. At the base of the grip there is an additional smaller cup. Hundreds of tricks requiring skill, patience, and hand-eye coordination may be performed with the Kendama. The Kendama may be played for self-satisfaction, or in a competitive setting. Many competitive Kendama associations exist across the globe.

DETAILED DESCRIPTION

Immaterial modifications may be made to the embodiments described here without departing from what is covered by the claims.

Refering to FIGS. 1-3, a skill toy 10 comprises a first piece 11 having a male member 12 extended from first piece 11, a second piece 15 having a receptacle 17 in second piece 15, and a tether 19 connected between the first and second pieces 11 and 15. First piece 11 may have a first end or male mating end 20, in which the male member 12 is extended from end 20. Second piece 15 may have a second end or female mating end 21, in which the receptacle is in the female mating end 21.

First piece 11 may have a first tether end 22 opposite the male mating end 20, and second piece 15 may have a second tether end 23 opposite the female mating end 21. Tether 19 may be connected between the first tether end 22 and the second tether end 23. The receptacle 17 may be sized larger in corresponding diameter than the male member 12 to allow for user error. Furthermore, the male member may be pointed, again to allow for user error when inserting the male member 12. The male member may be a peg, for example located along a center axis 91 (FIG. 5) of one or more of the first piece 11, second piece 15, and skill toy 10 , for further example coaxial to the central axis 91.

The tether may be elastic, inelastic, or both elastic and inelastic. Because the tether may attach to the first tether end 22 opposite the male mating end 20, various tricks are made possible. For example, the user may hold the second piece 15 above the first piece 11, dangling the first piece 11 with the male member 12 down, and then may quickly move the second piece 15 below the first piece 11 to mate with the first piece 11. Furthermore, the user, from the same starting position, may snap the first piece 11 above the second piece 15, and catch the male member 12 down, with a female landing surface 32 facing up and the female landing surface 32 supporting first piece 11. Additionally, the user may orient the mating end of either piece 11 or 15 outward upon establishing tension in the tether 19 to control movement of the either mating end and induce predictable and controllable rotation of the respective piece upon swinging either the first or second piece. Similarly, because the tether 19 attaches to the second tether end 23 opposite the female mating end 21, a reverse trick of the preceding paragraph may be performed, with the second piece 15 dangling below the first piece 11 in the starting position.

The skill toy may be constructed such that the first piece 11 has a first center of gravity 24 closer to the male mating end 20 than the first tether end 23, and the second piece 15 has a second center of gravity 25 closer to the female mating end 21 than the second tether end 23. Exemplary positions of centers of gravity 24 and 25 are shown in the Figures.

The first tether end 22 and the second tether end 23 may be convex, or hemi-spherical. Because the tether end may be convex, and the center of gravity for each piece is closer to each piece's respective mating end, several advantages may be apparent. For both pieces 11 and 15, either mating end 20, 21 may tend to become oriented towards the direction of motion in flight, making mating of the skill toy 10 in midair easier to accomplish. Air resistance allows the center of gravity to tend to go in front of the center of pressure, in this case in the direction of motion. Further, both pieces 11 and 15 will rotate with their respective mating ends 20, 21 moving at a relatively slower spinning speed than their respective tether ends 22, 23, because their respective mating ends 20, 21 are closer to the axis of rotation (center of gravities 24, 25) than their respective tether ends—making the skill toy easier to mate in midair.

The first center of gravity 24 may be closer than or equal to the first tether end 22 than to a tip end 26 defined by the male member 12. This may make it easier to catch the first piece 11 with tether end 22 on female landing surface 32 with male member 12 up, because the first piece 11 is not top heavy. In some embodiments the first piece 11 may be able to self-right with the male member 12 upwards when lying on the first tether end 22, for example when supported by the female landing surface 32.

Referring to FIGS. 5 and 6, the first piece 11 may have a first encircling sidewall 27, and the second piece 15 may have a second encircling sidewall 28. The skill toy 10 may have a mated position in which the male member 12 (FIG. 1) is inserted, as shown in FIG. 5. When mated the first encircling sidewall 27 may be adjacent and flush in relation to the second encircling sidewall 28 along an encircling joint 30 defined between the first encircling sidewall 27 and the second encircling sidewall 28. As shown in FIG. 5, all outer surfaces, such as tether ends 22, 23, and encircling sidewalls 27, 28, of a mated combination 31 of the first piece 11 and second piece 15 may be convex or planar when in the mated position. In the example shown, all out surfaces does not include tether connection parts such as nipple 13. The first encircling sidewall 27 and the second encircling sidewall 28 may be cylindrical in shape. This may allow the user to catch the first piece 11 with encircling sidewall 27 contacting the female landing surface 32 (FIG. 12), or alternately to catch the second piece 15 with female landing surface 32 contacting first ether end 22. The mated combination 31 may have a capsule shape, such as a stadium of rotation shape. Other shapes are possible: the mated combination 31 may form a rectangular box, or have a convex shape, or have other shapes. The first encircling sidewall 27 and the second encircling sidewall 28 may form a geometric shape in cross section, instead of the circular cross-section seen in FIG. 4. Magnets and other suitable clips or devices may be used to assist in mating.

When in mated position 29, the skill toy 10 may appear as a single convex object, and forms a compact shape for storage. Further, a single object with convex or planar surfaces may reduce snagging in pockets. A plane of symmetry 35 (FIG. 5) may be defined through a transition mating surface zone 36 between the first piece 11 and the second piece 15 when in the mated position 29.

Referring to FIGS. 12 and 13, the female mating end 21 may have a planar or concave landing surface 32 surrounding the receptacle 17, and the second encircling sidewall 28 may share a perimeter edge 33 with the female mating end 21. The planar or concave landing surface 32 may be sized sufficient to statically support the first piece 11 in an unmated position 34. There may be many possible static positions, for example if landing surface 32 faces up and supports encircling sidewall 27 of first piece 11. Female landing surface 32 may be contoured to fit the curved profile of first piece 11. Landing surface 32 may have a radial width 97 equal to or longer than an axial length 99 of the first piece 11 from male end 20 to tether end 22. In one embodiment, a concave landing surface 32 serves to ensure a flush or contiguous seal between the perimeter edges 38 and 39 of the two pieces 11, and 15, respectively (FIG. 10). The skill toy 10 may have more than one perimeter edge. Referring to FIG. 5 the first encircling sidewall 27 may share a first perimeter edge 38 with the first end 20, the second encircling sidewall shares 28 a second perimeter edge 39 with the second end 21, and the first perimeter edge contacts the second perimeter edge to define the encircling joint 37 when in the mated position 29.

Referring to FIG. 5, the skill toy may have respective transitional surfaces 48 and 49, of the first encircling sidewall 27 and second encircling sidewalls 28, adjacent the encircling joint 37 that collectively define a concave or planar shape along an axial direction 57 across the encircling joint 37.

Referring to FIG. 2, tether 19 may connect by suitable connection mechanisms between first and second pieces 11 and 15. For example, a nipple 13 may extend coaxially with axis 91, nipple 13 being pierced laterally to define a passage 93 for tether to tie around as shown. As well, second piece 15 may have a hole 16 bored from receptacle 17 to second tether end 23 coaxial with axis 91, and tether 19 may be inserted into hole 16 and tied in a knot larger than the diameter of hole 16. Hole 16 is also shown in FIG. 4. FIGS. 7-9 illustrate another suitable mechanism of connecting tether 19 to first piece 11 via a hole 18 drilled laterally through first tether end 22. Tether 19 may be passed through hole 18 and tied off. Other suitable connection mechanisms may be used.

Each skill toy 10 may have more than one set of corresponding male and female members. A user may manipulate skill toy 10 skillfully in order to perform one or more juggling tricks. A user may practice with the toy to improve upon specific skills such as hand-eye coordination, balance, and flexibility. The user of a juggling toy improves upon these skills by learning increasingly complex and creative juggling tricks. Some embodiments of the skill toy are advantageous because such skill toys 10 are compact and portable when the male and female pieces are fit together to form the capsule shape. Some embodiments contain no intricate or easily breakable parts, thus providing a durable toy that will not easily break if dropped.

In some embodiments, the user can hold any part or parts of the toy while manipulating the other part or parts to perform juggling tricks. Having the two or more parts of the toy strung together minimizes the chance that one part of the toy will be dropped in the event a juggling trick is not successfully completed, and it also presents the user with unique juggling trick possibilities involving manipulation of the string.

In the claims, the word “comprising” is used in its inclusive sense and does not exclude other elements being present. The indefinite articles “a” and “an” before a claim feature do not exclude more than one of the feature being present. Each one of the individual features described here may be used in one or more embodiments and is not, by virtue only of being described here, to be construed as essential to all embodiments as defined by the claims.
