Abstract
A twirling disc adapted to be used by either a novice twirler or an expert twirler. The disc is provided with a pliable covering on one of its faces. The opposite face is provided with a hard covering. A novice twirler effects twirling of the disc by applying his twirling finger to the pliable covered face of the disc. An expert twirler engages his twirling finger with the face of the disc having a hard covering.
Description

BACKGROUND OF THE INVENTION
Many people find enjoyment from twirling a disc while such disc is balanced upon their index finger. Generally such discs are formed of a rigid material. Although an expert has comparatively little difficulty twirling a rigid disc, novice twirlers, and particularly children, find such twirling to be a difficult task.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a twirling disc which is adapted for use by either a novice twirler or an expert twirler.
A further object of the invention is to provide a twirling disc having one of its faces defined by a pliable material, and its other face defined by a hard material, with the pliable material being engaged by the finger of a novice twirler, and the hard material being engaged by the finger of an expert twirler.
Yet a further object of the present invention is to provide a twirling disc of the aforedescribed nature which is rugged of construction and yet may be manufactured at low cost.
These and other objects and advantages of the present invention will become apparent from the following detailed description of a preferred embodiment thereof.

FIG. 1 is a perspective view showing a preferred form of twirling disc embodying the present invention, with the pliable material face of said disc facing upwardly;
FIG. 2 is a perspective view similar to FIG. 1, but showing the hard material face of said disc facing upwardly;
FIG. 3 is a central vertical sectional view of a first embodiment of said twirling disc;
FIG. 4 is a perspective view showing how said twirling disc may be utilized by an expert twirler;
FIG. 5 is a view similar to FIG. 4, but showing how said twirling disc may be utilized by a novice twirler;
FIG. 6 is a top plan view of a second form of twirling disc embodying the present invention; and
FIG. 7 is a vertical sectional view taken in enlarged scale along line 7--7 of FIG. 6.





DETAILED DESCRIPTION
Referring to the drawings, there is shown in FIGS. 1-5 a first embodiment of a twirling disc of the present invention. Such disc being designated D-1. Twirling disc D-1 includes an rigid annular rim 10 defining the periphery of such disc. Referring particularly to FIG. 3, the lower portion of rim 10 is bridged by a web 12 of hard material defining the lower face of the twirling disc. Preferably, rim 10 and web 12 will be integral. The material from which rim 10 and web 12 is formed may be of a comparatively hard material, such as synthetic plastic, paper or metal. The recess defined by rim 10 and web 12 receives an inverted ring, the upper surface of which coincides with the upper end of rim 10. Ring 13 includes depending inner and outer flange 14 and 15 that abut the upper surface of web 12. The annular hole 16 defined by inner flange 14 is shown filled with a pliable material 14 defining the upper face of the twirling disc. Such material is secured within annular hole 16 as by a suitable adhesive. The pliable material 17 may be of a spongy or foam texture, with such sponge or foam being formed of a conventional synthetic plastic.
Referring now to FIG. 4, the twirling disc D-1 is shown being twirled while balanced upon the index finger of an expert or experienced twirler. It will be observed that his index finger is engaged with the hard material face of the twirling disc. In FIG. 5 the twirling disc is shown being twirled while balanced upon the index finger of a novice twirler. It will be observed that his index finger is engaged with the portion of the face of the twirling disc defined by pliable material 17. It should be understood that it is, of course, far easier for the twirling disc to be operated with the index finger of a twirler in engagement with the pliable material than with the hard material.
The aforedescribed twirling disc of the present invention permits a single disc to be employed by both novice and experienced twirlers. In practice, a novice twirler would begin his twirling activities using the pliable material face of twirling disc. Upon gaining confidence in his twirling abilities, the twirler would then reverse the faces of the twirling disc and balance such disc with his index finger in engagement with the hard material face of the twirling disc.
Referring now to FIG. 6, there is shown a second twirling disc D-2 embodying the present invention. This embodiment utilizes a rim 10' having its lower portion bridged by an integral material, preferably the same material as that utilized in forming the rim. An integral collar 28 extends radially inwardly from the upper edge of the rim to define a circular opening 29. In this embodiment of the invention, a round sheet of pliable material 30 is stretched across the opening 29. The radially outer surface of such material 30 is adhered to the underside of collar 28 by a suitable adhesive. Suitable materials from which to form sheet 30 are cloth, sponge, natural or synthetic rubber or a rubberized textile. This embodiment of twirling disc is utilized in the same manner described in connection with the twirling disc D-1.
Various modifications and changes may be made with respect to the foregoing detailed description without departing from the spirit of the present invention.
