Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A twirling disc toy adapted for use by either a novice twirler of an expert twirler, said twirling disc comprising: a rim defining the periphery of said twirling disc; a pliable material extending across said rim on one face thereof; and a hard material extending across said rim on the opposite face thereof, said pliable material for contacting the twirling finger of a novice twirler and said hard material of the disc for contacting the finger of an expert twirler.
Claim 2
Dependent Claim
80 words
A twirling disc toy adapted for use by either a novice twirler of an expert twirler, said twirling disc comprising: a rim defining the periphery of said twirling disc; a pliable material extending across said rim on one face thereof; and a hard material extending across said rim on the opposite face thereof, said pliable material for contacting the twirling finger of a novice twirler and said hard material of the disc for contacting the finger of an expert twirler.
Claim 3
Dependent Claim
18 words
A twirling disc as set forth in claim 1, wherein said rim and said hard material are integral.
Claim 4
Dependent Claim
17 words
A twirling disc as set forth in claim 1, wherein said pliable material is formed of sponge.
Claim 5
Dependent Claim
20 words
A twirling disc as set forth in claim 1, wherein said pliable material is a sheet stretched across said rim.
Claim 6
Dependent Claim
216 words
A spinning toy comprising a cylindrical disc formed with a circumferential rim and a first and second surface, said first and second surface being substantially parallel and each lying in a plane approximately perpendicular to the longitudinal axis of symmetry of said cylindrical disc, said first surface being characterized by a hard, smooth textured surface, and said second surface being characterized by a pliable region disposed about and generally centered about said longitudinal axis of said disc, said pliable region being surrounded by a nonpliable region extending to said rim, said pliable region of said second surface being characterized by a soft, deformable textured surface, adapted for contact with the twirling finger of a novice twirler whereby spinning of said toy is facilitated by contact between the twirling finger of a novice twirler and said pliable region, said finger of said novice twirler deforming said pliable region at the point of contact with said twirling finger, thereby increasing the degree of frictional engagement between said twirling toy and the twirling finger of a novice twirler, and whereby said first surface is adapted for contact with the twirling finger of an expert twirler so that frictional engagement between the twirling finger of said expert twirler and said first surface is minimized by said smooth, hard textured surface.
Claim 7
Dependent Claim
216 words
A spinning toy comprising a cylindrical disc formed with a circumferential rim and a first and second surface, said first and second surface being substantially parallel and each lying in a plane approximately perpendicular to the longitudinal axis of symmetry of said cylindrical disc, said first surface being characterized by a hard, smooth textured surface, and said second surface being characterized by a pliable region disposed about and generally centered about said longitudinal axis of said disc, said pliable region being surrounded by a nonpliable region extending to said rim, said pliable region of said second surface being characterized by a soft, deformable textured surface, adapted for contact with the twirling finger of a novice twirler whereby spinning of said toy is facilitated by contact between the twirling finger of a novice twirler and said pliable region, said finger of said novice twirler deforming said pliable region at the point of contact with said twirling finger, thereby increasing the degree of frictional engagement between said twirling toy and the twirling finger of a novice twirler, and whereby said first surface is adapted for contact with the twirling finger of an expert twirler so that frictional engagement between the twirling finger of said expert twirler and said first surface is minimized by said smooth, hard textured surface.
Claim 8
Dependent Claim
72 words
The spinning toy of claim 5 wherein said pliable region is disposed at least partially into said cylindrical disc and extends below said second surface, and is formed of a pliable material of sufficient deformability that the weight of said disc against the finger of said twirler in contact with said pliable region substantially deforms said pliable region to form an indentation therein in the proximity of said contact with said finger.
Claim 9
Independent Claim
176 words
A method of learning to spin an object by practicing with a cylindrical disc having a first hard, smooth surface, and a second surface including a pliable region comprising the steps of: spinning said cylindrical disc with a finger in contact with said pliable region wherein frictional contact between said finger and disc is enhanced by deformation of said pliable region by said finger; repetitively continuing the spinning of said cylindrical disc with contact of said finger with said pliable region until a high degree of confidence and ability is obtained by a twirler to spin said cylindrical disc with said finger in contact with said pliable region by virtue of said repetition; turning said disc to contact said disc with said finger on said first surface; and repetitively spinning said disc with said finger in contact with said hard, smooth first surface until a high degree of confidence and ability in spinning said disc with said finger in contact with said first surface is achieved, whereby the user acquires an ability to spin said object.
Claim 10
Independent Claim
176 words
A method of learning to spin an object by practicing with a cylindrical disc having a first hard, smooth surface, and a second surface including a pliable region comprising the steps of: spinning said cylindrical disc with a finger in contact with said pliable region wherein frictional contact between said finger and disc is enhanced by deformation of said pliable region by said finger; repetitively continuing the spinning of said cylindrical disc with contact of said finger with said pliable region until a high degree of confidence and ability is obtained by a twirler to spin said cylindrical disc with said finger in contact with said pliable region by virtue of said repetition; turning said disc to contact said disc with said finger on said first surface; and repetitively spinning said disc with said finger in contact with said hard, smooth first surface until a high degree of confidence and ability in spinning said disc with said finger in contact with said first surface is achieved, whereby the user acquires an ability to spin said object.
Claim 11
Dependent Claim
70 words
The method of claim 7 wherein said step of spinning said disc with said finger contacting said second surface having said pliable region includes substantially deforming said pliable region by contact of said finger therewith to form an indentation in said pliable region, thereby enhancing engagement and frictional contact between said finger and said spinning disc to aid ease of spinning until confidence and ability is obtained by said twirler.
