U.S. provisional patent application 61/732,299, entitled “A Dual Purpose Yo-Yo System”, naming Franklin Labarbara and Todd Rywolt as inventors filed 1 Dec. 2012.

BACKGROUND

1. Field of Use
These teachings relate generally to a Yo-Yo system and in particular to a transformable dual purpose yo-yo-system.
2. Description of Prior Art (Background)
Yo-yo toys have proven to be a long standing and well known toy product. The basic components of a Yo yo generally comprise a body usually formed of a pair of generally disk-like body halves joined by a center shaft. The body halves are spaced apart slightly to form a center space. A string has one end secured about the center shaft and the remaining end configured to be looped around the user's fingers with a slip knot or the like. The attachment of the string end to the center shaft of the Yo-yo is carried forward in either a fixed attachment or a loop formed to encircle the center shaft.
In a typical Yo-yo play pattern, the outer end of the string is secured to the user's finger and the string is wound upon the center shaft until the Yo-yo body is received within the user's hand. Thereafter, the user throws the Yo-yo body downwardly which unwinds the string as the Yo-yo body falls simultaneously spinning the body. At the full extension of the string, the spinning momentum of the Yo-yo body rewinds the string and raises the Yo-yo upwardly upon the string to be caught in the user's hand. For those Yo-yo's of the type having a fixed attachment of the string end upon the center shaft this simple up and down pattern is repeated and constitutes the extent of play with variation of use.
A substantially greater flexibility of use and amusement is provided by Yo-yo's in which the string end at the center shaft of the Yo-yo is simply looped about the center shaft. This allows the spinning Yo-yo body to spin within the string loop at the bottom extension of the string and greatly increase the flexibility of toy play pattern. Thus, as the user throws the Yo-yo body downwardly unwinding the string and spinning the Yo-yo it continues to spin at the bottom end of the string allowing various tricks to be performed. The user raises the spinning Yo-yo body by imparting a sharp tug to the string which wraps and binds the lower end of the spring upon the shaft and raises the Yo-yo.
The width of the gap between the yo-yo halves is critical to proper control of the yo-yo. If the gap is too small, the yo-yo may not sleep, tending, instead, to frictionally grip the string notwithstanding the presence of tension in the string. If the gap is too wide, the inwardly facing surfaces of the yo-yo halves may not. be able to engage the string with sufficient friction.
In addition, the extended popularity of Yo-yo toys have prompted practitioner's in the art to provide a great variety of such toys. For example, U.S. Pat. No. 2,676,432 issued to Field sets forth a whirling toy having a Yo-yo defining a pair of body halves and a string secured to the center shaft. Each body half defines a clear outer surface and a cavity within which a toy figure is rotatably supported.
However, there is no known prior art that integrates the body of the Yo-yo as part of the toy. Thus, there remains a need in the art for evermore varied and interesting Yo-Yo type products.

DETAILED DESCRIPTION

Referring first to FIGS. 4, 8, and 9, the yo-yo includes a pair of yo-yo halves 10, 12 which preferably are formed from injection molded plastic, although they may be formed from other materials such as wood, metal or a combination thereof. The yo-yo halves may be about 2 and ¼″ diameter. The inwardly facing surfaces 14, 16 of the yo-yo halves 10, 12 are provided with cylindrical sockets 18, 20 which, in turn, are formed with internal bores 22, 24. The sockets 18, 20 and internal bores 22, 24 are aligned along the axis of rotation of the yo-yo. The yo-yo halves are essentially identical. Commercially available threaded inserts 26, 28, are embedded in the internal bores 22, 24, respectively. An axle 30, which may be formed from steel rod, having threaded ends 32, 34 is screwed into the threaded inserts 26, 28 as shown in FIGS. 4 and 9. The juncture of the unthreaded portion of the axle 30 with the threaded ends 32, 34 defines shoulders 36, 38 (see FIG. 9) which abut facing shoulders 40, 42 formed on the threaded inserts 26, 28.
The inwardly facing surfaces 14, 16 of the yo-yo halves may be provided with an arrangement of radially extending raised ribs 45 surrounding the sockets 18, 20 in somewhat of a starburst pattern. The ribs may be of the order of 0.125″ long and may extend above the associated surfaces 14, 16 about 0.010″. The ribs enhance the ability of the yo-yo to engage the string when retrieving the yo-yo. In accordance with one aspect of the invention, the space 44 between the yo-yo halves 10, 12 adjacent the spool is among the critical features of the invention and, therefore, it is important to assure that the threaded inserts 26, 28 are precisely located in the yo-yo halves 10, 12. Where the yo-yo halves 10 12 are formed from injection molded plastic, it is possible to locate the inserts 26, 28 with such precision using conventional insert molding techniques.
The yo-yo includes a generally cylindrical spool 46 rotatably mounted on the axle 30, the ends of the spool 46 being received, symmetrically, within the sockets 18, 20 of the yo-yo halves 10, 12. By way of example, the axle may be of the order of 0.156″ diameter the inner diameter of the spool 46 being about 0.005″ to 0.008″ in diameter larger than the axle. The spool 46 preferably is provided with to circumferential groove 48 about which the yo-yo string (not shown) may be fastened. The yo-yo is intended to be used with standard yo-yo strings commercially available. Preferably the string is fastened in a double loop so that the spool 46 will not rotate with respect to the string. The spool 46 is formed from a polymeric material having good lubricity properties. For example, DELRIN available from DU PONT has been found to be a suitable plastic. The polymeric material also should be machined to precise tolerances. Other plastics having good lubricity and machinability properties may be employed. The outer diameter of the spool 46 is slightly less than the diameter of the sockets 18, 20 so that when the yo-yo is suspended from its string, the yo-yo halves 10, 12 may spin freely without interference with the circumference of the spool. The axle 30 may be coated with a light film of lubricant further to enhance the low frictional characteristics of the device.
in order that the yo-yo may display superior long duration spinning, it is critical that the axial play of the spool 46 on the shaft (the difference between spool length and distance between ends of sockets 18, 20) be no greater than about 0.018″ and preferably about 0.015″. The clearance may be as low as about 0.001″. As long as the axial play is maintained within those limits, the device will display superior spinning for long times Also critical to the performance of the yo-yo is the facility with which the yo-yo may be returned to the user from a sleeping configuration with a simple flick of the wrist. By maintaining the space 43 between the facing ribs 45 of the yo-yo halves 10, 12 adjacent the spool between about 0.075″ to 0.090″, (space 44 being about 0.095″ to 0.105″) the yo-yo will return easily and controllably even though the string is attached to the freely rotatable spool 46. If the radial ribs 45 are omitted, the yo-yo halves may be placed closer together, bringing space 44 to about 0.075″ to 0.090″. Thus, the present invention achieves the desired characteristics of long spins and easily controlled return without requiring the use of complex clutches.
Referring also to FIG. 1 there is shown an exploded view one embodiment of a transformable Yo-yo system in accordance with the present invention. Shown in FIG. 1 is yo-yo base 100.
