reference will now be made in detail to several embodiments of the invention that are illustrated in the accompanying drawings . wherever possible , same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps . the drawings are in simplified form and are not to precise scale . for purposes of convenience and clarity only , directional terms , such as top , bottom , left , right , up , down , over , above , below , beneath , rear , and front may be used with respect to the drawings . these and similar directional terms should not be construed to limit the scope of the invention in any manner . the words “ connect ,” “ couple ,” and similar terms with their inflectional morphemes do not necessarily denote direct and immediate connections , but also include connections through mediate elements or devices . furthermore , such terms as “ toy ” and “ whirling wheel toy ” are used interchangeably . in accordance with the invention , as depicted in fig1 - 6 , a throwable and aerodynamic toy or whirling wheel toy 10 combines a disk 12 with a centrally positioned ball , rounded component , structure 14 . specifically , whirling wheel toy 10 comprises a one - piece molded device with flying disk 12 having a top side 13 and a bottom side 15 and circumscribed by a rounded rim 18 . in a preferred configuration , rim 18 is formed with a greater thickness than the peripheral region of flying disk 12 and , thus , protrudes outwardly from opposite sides 13 and 15 of flying disk 12 . ball 14 includes a pair of top and bottom regions 19 , 20 , respectively , consisting of like - shaped protruding convexities or halves extending from top and bottom surfaces 13 and 15 , respectively , of disk 12 in an opposing fashion . both convexities are centered about an axis of symmetry at the center of disk 12 and substantially perpendicular to its top and bottom surfaces 13 and 15 , respectively . in other words , the convexities are concentric to the disk . when in flight , whirling wheel toy 10 has the appearance of a “ flying saucer ” or unidentified flying object , giving it added play appeal . the toy may be thrown in the manner of a frisbee and , upon landing , may keep bouncing due to the resiliency of the ball &# 39 ; s material . in play , whirling wheel toy 10 is thrown into the air with a spinning motion imparted thereto by grasping disk 12 with the fingers . more specifically , whirling wheel toy 10 is preferably grasped in one hand with the thumb carried on top of disk 12 and the four fingers pressing against the bottom of disk 12 . the toy is then typically projected into the air in a wrist - snapping motion . consequently , during an airborne flight , whirling wheel toy 10 rotates about its axis of symmetry . the angle at which disk 12 is held controls the particular flight trajectory assumed by whirling wheel toy 10 . typically , the inventive toy is propelled in an upwardly arching flight pattern so as to be held aloft aerodynamically for a time until assuming a downward trajectory toward the earth . if the trajectory of the toy &# 39 ; s flight is correct , it typically lands on bottom half 20 of ball 14 , bounces and generates a noise a few times giving a pet time to catch it in the air . turning now specifically to fig1 , whirling wheel toy 10 may be packaged individually to meet the individual needs of dogs classified in accordance with their respective size , which typically includes large , medium and small size dogs . in an alternative embodiment , however , more than one toy 10 can be packaged together so as to constitute a kit . one of the reasons for having the kit is that a pet may like one of the packaged toys and , for some reason , ignore the other one regardless of the size of toys 10 . whirling wheel toy 10 is preferably a single continuous unit , which is made from a moldable material selected from a substantially rigid material , such as plastic or foam , or a flexible material , such as rubber or plastic . as is illustrated in the embodiment of fig1 through 6 , top and bottom halves 19 , 20 of ball 14 , respectively , are semi - spherically - shaped halves . however , although not shown , the ball may have a shape differing from a round ball , such as crown 21 wherein it is advantageously shaped for better bounce and / or easier deformability , and be provided with two generally conically or frustoconicaly shaped opposite halves extending from the opposite sides of flying disk 12 so as to form a substantially elliptically - shaped body . in accordance with one of the embodiments of the invention , both semi - spherical top and bottom halves 19 , 20 of ball 14 , respectively , are made from uniformly - densed polymeric material . however , in an alternative embodiment , half 20 protruding from bottom surface 15 of disk 12 may be made from a more dense material than the opposite half and , thus , be somewhat heavier . configured in accordance with the latter embodiment , whirling wheel toy 10 may have a high probability of landing on the central region rather than wobble and land on rim 18 and , as a consequence , exhibit superior bouncing characteristics upon landing , which is particularly liked by dogs . the disk 12 is of a substantially circular outline , and it may assume any appropriate diameter to be thrown by the pet owner . it may likewise assume any appropriate thickness defined between top surface 13 and bottom surface 15 of disk 12 . in one embodiment of the invention , as shown in fig1 through 6 , opposite top and bottom surfaces 13 and 15 , respectively , extend in parallel planes . in an alternative embodiment , which is not shown , disk 12 may be extruded so as to have the top and bottom surfaces each having a respective convex shape cumulatively defining a substantially elliptical cross - section of the disk . in particular , the thickness of disk 12 defined between its top and bottom surfaces 13 and 15 may gradually increase towards the center of the disk reaching its maximum in a region that surrounds ball 14 . in the latter embodiment , whirling wheel toy 10 may achieve high and long flight trajectories due to its better aerodynamic qualities . in any case , the thickness of disk 12 is selected so as to provide the pet owner with a comfortable grip . whirling wheel toy 10 may be either hollow or semi - solid , so long as surfaces 13 and 15 of disk 12 are substantially rigid to retain the shape of whirling wheel toy 10 during use and is sufficiently light in weight for throwing . nonexclusive examples of substantially rigid materials that might form a solid whirling wheel toy 10 include foam , plastics , and rigid papers such as cardboard . if a soft , flexible material , such as rubber , is employed to form whirling wheel toy 10 , the latter would be semi - solid and the flexible material would have sufficient rigidity such that whirling wheel toy 10 substantially retains its shape during use . in a semi - solid toy 10 , the material , used to form toy 10 , can have a controllably different density within disk 12 . by carefully choosing the density of the material for various regions of disk 12 , inventive whirling wheel toy 10 can have different flight characteristics . for example , if whirling wheel toy 10 having the capability of sustained flight is desired , the density of the material near rim 18 will be greater than the density of the material near ball 14 . the body of disk 12 may be continuous or provided with a plurality of spaced openings 16 extending between and through the disk &# 39 ; s opposite top and bottom surfaces 13 and 15 , respectively . it has been found that configuring and dimensioning whirling wheel toy 10 in a specific manner may enhance its aerodynamic characteristics . turning to fig4 and 5 , each of openings 16 is preferably provided with an oval shape and has a ratio of a length of its major axis , dol , to a length of its minor axis do of between about 2 to 3 in order to provide whirling wheel toy 10 with good aerodynamic characteristics . however , the oval shape is not the only shape that may be selected for openings 16 . other shapes , both regular and irregular , may be used as well . empirically , it has been found that a ratio of about 2 . 3 to 2 . 7 between an inner diameter , dbi , which is defined between opposite inner boundaries of rim 18 , which has a diameter de , and an outer diameter dc of ball 14 may also contribute to the improved aerodynamic characteristics of whirling wheel toy 10 . still a further feature beneficially affecting the aerodynamics of disk 12 , which has a thickness dth , includes selecting a ratio between the disk &# 39 ; s outer diameter , dbo , and outer diameter , dc , of ball 14 of about 2 . 8 to 3 . an interesting feature of the inventive toy includes a fascinator such as squeaker 22 ( fig6 ) provided within bottom half 20 of ball 14 and operative to generate a noise upon impact with the ground . since a material of ball 14 deforms upon impact and springs back to its original shape , the noise is produced each time bottom half 20 of ball 14 touches the ground . a configuration of squeaker 22 is known and includes an inner hollow portion 28 , perforated plastic membrane 26 , outer sleeve 24 , inner sleeve 30 and outer flange 32 with an air intake port that lies flush with the outer surface of ball 14 . squeaker 22 is so positioned that air may be introduced into or expelled from the interior of ball 14 only through the squeaker . upon collapsing or expanding of ball 14 , the squeaker is traversed by air stream through the air intake port so as to produce a noise that usually attracts a pet , which either tries to catch the bouncing toy or simply chews on it . hence , each time when the animal bites ball 14 , or releases it , air passes through the squeaker producing a noise . an optional feature is contemplated to be its illumination from within during play . specifically , the toy 10 could be hollow and made of a translucent material , such as plastic or foam , and an illuminating means could be positioned internally in whirling wheel toy 10 . this document describes the inventive toy for illustration purposes only . neither the specific embodiments of the invention as a whole , nor those of its features limit the general principles underlying the invention . in particular , the invention is not limited to any specific configuration of squeaker 22 , shapes of ball 14 and rim 18 . the specific features described herein may be used in some embodiments , but not in others , without departure from the spirit and scope of the invention as set forth . many additional modifications are intended in the foregoing disclosure , and it will be appreciated by those of ordinary skill in the art that in some instances some features of the invention will be employed in the absence of a corresponding use of other features . the illustrative examples therefore do not define the metes and bounds of the invention and the legal protection afforded the invention .
