a toy in accordance with the invention is intended herein to broadly embrace any and all suitable structural configurations providing at least two regions , each of which , due to differing physical characteristics of the regions themselves or by virtue of positional placement of other structure of the toy , is accessed to a relatively greater or lesser degree by a dog when picking up the toy in its mouth . it will be understood that such suitable structural configurations are not intended herein to be limited to any precise shape or size , and selection of such parameters in the practice of the invention will often be dictated by design preference , and preferred manner and ease of gripping of the toy by both the user and the dog . the characteristics referred to above which control the respective relative degrees of animal interest in picking up the toy by one region or another may be sensory - based , i . e ., involving such factors as smell , taste , appearance , surface feel , hardness , etc ., and / or may be a structural feature which physically inhibits or discourages access by a dog &# 39 ; s mouth to a given one of the regions designed to be held by a user and therefore intended to be accessed to a lesser relative degree by the dog or other animal . referring now to the figures , fig1 and 2 depict an embodiment of the toy in accordance with the invention , generally designated 10 . in accordance with the illustrated example , toy 10 is structurally of elongated dimension and presents a general shape visually reminiscent of a bone , i . e ., having the appearance of enlarged end portions relative to a narrower central portion extending therebetween . as shown in the figures , toy 10 includes a bar 1 comprising a central region 1 a and opposed end regions defining two handles 1 b . a pair of shields 2 are disposed along the bar 1 in a position adjacent to the opposed ends thereof . shields 2 may be configured in any suitable shape which effectively restricts or inhibits access by the mouth of the animal to the handles 1 b , yet allows grasping thereof by a user inserting a hand 3 into an inner region 4 of shields . conveniently , the shields 2 are , for example as shown , cup - shaped , having open ends arranged to face outwardly in a direction along a longitudinal axis a , and as further shown , advantageously extend past terminal ends of handles 1 b . the openings in the shields 2 are preferably of sufficient size to permit the hand 3 to be inserted and to grasp the handle 1 b disposed therein , and yet advantageously still small enough to discourage a dog from trying to insert its snout in an attempt to bite the handle 1 b or the walls of the shield 2 . the shield can optionally include cutouts 5 , for example , to reduce wind resistence when thrown or just simply to give the toy 10 a more attractive appearance . the elongated central region 1 a , which serves to provide the animal access region , is advantageously appropriately dimensioned to be comfortably receivable between the jaws of a dog and can , if so desired , be textured , patterned , flavored , covered by any suitable material , etc ., to further enhance animal appeal . the handles 1 b , by virtue of being at least partially shrouded by shields 2 , serve to provide animal restricted regions . conveniently , in particular from the standpoint of manufacture and as shown in the example of fig1 and 2 , the handles 1 b are simply axial extensions of the elongated central region 1 a extending between the shields 2 , and having either the same , greater or lesser diameter for comfortable grasping by the user . during use , the user simply grabs either of the shielded handles 1 b and throws the toy 10 as one would throw a stick or the like . when retrieving the toy 10 from the ground after the toy 10 is thrown , the dog is presented with the elongated central region 1 a which is elevated above the ground by the greater diameter shields 2 disposed at opposed ends of the toy 10 which serve to support same on the ground , and the dog is therefore most likely to pick the toy up by the animal access region presented by elongated central region 1 a . it is noted that , although the particular example described above employs two handles 1 b , only one gripping region , conveniently in the form of a suitable handle structure , need be provided at one position of the toy 10 in accordance with an embodiment of the invention . the embodiment shown in fig1 and 2 is conveniently an integral structure , produced as one piece , for example , in practice , by injection molding or other suitable process . however , if so desired , the toy ( including embodiments later described herein or others made in accordance with practice of the invention ) may be comprised of an assembly of parts , for example in instances where injection molding of a unified toy is not a practical option , or where it is desired that the toy have different physical characteristics over different regions to achieve the objectives of the invention ( i . e ., to provide , for example , varying sensory - based stimulus ) or simply to provide a more visually appealing or comfortable feel for consumers at point of purchase and / or during use . fig3 a and 3 b illustrate merely two examples of the virtually limitless possibilities for such assemblies , as will be apparent to one skilled in the art . referring to fig3 a , a toy 10 ′ is comprised of a rod 1 ′ which includes a handle 1 b ′ and a central region 1 a ′ molded as an integral unit . a shield 2 ′ is made of a resilient material stretchable to a degree sufficient to permit assembly by slidable reception of the shield past the handle 1 b ′ thereby to allow a reception portion 2 a ′ of the shield 2 ′ to be captively received in a groove formed in the rod 1 ′ at an axial juncture of the handle 1 b ′ and the central region 1 a ′ when an applied stretching force is relieved . turning now to fig3 b , a toy 10 ″ includes a central member 1 a ″ made , for example , of a moderately rigid or shape - retaining material , and an outer sleeve 1 c ″ of a softer , and optionally , absorbent material , such as a pile , woven fabric , carpet - like material , etc .. referring now to fig4 and 5 , another embodiment of a toy is depicted , generally designated as numeral 20 . toy 20 includes a series of members 21 ( preferably at least three , and in the depicted example of fig4 and 5 , four ) having a longitudinal dimension running co - directionally with a central axis a ′ of the toy , and which are circumferentially spaced - apart about the central axis a ′ ( each equally spaced circumferentially 90 ° apart in the depicted example ) and having at least structural portions located radially outward from the central axis a ′. in a particularly advantageous variant of this embodiment , outermost edges of the members are shaped to collectively describe a generally spherical envelope , as shown in the particular example depicted . at least one hand - grasping region ( preferably two , as shown ) is provided , advantageously , though not necessarily , through which the central axis a ′ passes , and more advantageously in the form of a rod - shaped handle 22 ( preferably two rod - shaped handles 22 , as shown in the example ) longitudinally aligned with the central axis a ′. each of the members 21 and the handles 22 are mutually secured , either by integral molding , fabrication , or assembly . radially outward portions 21 a of the members 21 are extended outward from a center c of the toy 20 in the axial direction such that they extend past an axial position of an inwardmost end of the handle 22 a , thereby at least partially shielding the handles 22 , such that the handles 22 serve to provide the animal restricted regions . in a preferred case , two handles 22 disposed in opposed positions along the central axis a ′ are provided ( as shown in fig4 ), and terminal ends 21 b of the members 21 extend approximately to an axial position p corresponding to outwardly facing terminal ends 22 b of the handles 22 , thereby advantageously shielding handles 22 over a major , or substantially entire , portion of their axial extent . in the presently described embodiment , the circumferentially spaced - apart members 21 each presents an animal access region , particularly accessible by the animal at the radially outward portions 21 a of the members 21 . it should be noted that by virtue of the geometry of this depicted embodiment of fig4 and 5 , the toy 20 is self - righting , i . e ., when tossed onto a relatively horizontal surface , the toy 20 will come to rest with the handles ( and central axis a ′) extending horizontally , and generally parallel with the support surface . this feature provides particular advantage , since when thrown during , for example , fetch play , the toy 20 will right itself in this manner , thereby orienting the circumferentially spaced - apart members 21 , each which presents an animal access region , in a raised position from the ground so as to be particularly accessible by the animal . it is noted that by selecting an appropriate center of gravity , alternative toy designs having other configurations can incorporate this self - righting feature . gripping regions , shown in the depicted example in the form of handles 22 , and which provide the animal restricted regions , need not be in the form of formal handle structure as in the present example , but instead may rather simply be comprised of a hand - retainable region accessible by a hand of a user , which region is at least partially shielded by the terminal end structure of the members 21 providing the animal access regions . an example of such embodiment is depicted in fig6 and 7 , in which an alternate toy embodiment is depicted , generally at 30 . toy 30 includes three members 31 spaced apart circumferentially about a central axis a ″. in the example shown , although not essential to practice of the invention , the members are equally spaced circumferentially by angular intervals of 120 °. the present embodiment is made in general accordance with the above - discussed considerations as the prior - described embodiment , and therefore description of analogous features need not be repeated , and only the notable differences will be addressed . in the embodiment , formal handles are omitted , and hand gripping regions 32 are instead provided at a juncture of the members 31 where they meet at the central axis a ″ in a position axially inward of ( i . e ., recessed back from ) terminal ends 31 b of the members 31 , whereby the extended portions of members 31 proximate to the terminal ends 31 b thereof partially shield access by the animal to the gripping regions 32 which thereby serve to provide the animal restricted regions . it is noted that , alternative to a rod - like handle or a simple gripping region as described above , any number of other suitable configurations can be used in satisfactory manner to satisfy the spirit of the invention . for example , as depicted in fig8 another embodiment of a toy is shown , generally designated 40 . toy 40 is the same in form as the embodiment of fig6 and 7 , and description relating to analogous features , such as the members 41 ( corresponding to members 21 and 31 ) will therefore not be repeated . however , instead of a simple gripping region being provided in a position on the toy recessed back from terminal ends of the members , holes 43 are provided in a location corresponding to the gripping regions 32 in the embodiment of fig6 and 7 through which a rope 42 is passed in general alignment with a central axis a ′″. knots 42 a tied in the rope serve as convenient means for retaining the rope 42 to a remainder of the toy 40 . additional knots 42 b adjacent terminal ends of the rope 42 b optionally facilitate grabbing by a hand of the user . in this embodiment , the free end portions of each of the rope 42 serves as a handle providing the animal restricted regions designed to be accessed by the hand of the user and not the animal . it is noted that in each of the embodiments of fig4 - 8 , the members 21 , 31 , 41 have a cutout portion between the radially outward portions 21 a , 31 a , 41 a thereof and the central axis a ′, a ″, a ′″. however , such structural feature is not deemed essential to the invention , and the members could alternatively be made as solid fin - like structures which radiate from the central axis . additionally , such fin - like structures could optionally thicken in profile as they extend further from the axis to better provide a biting structure for the animal at the radially outermost regions most accessible by the snout of a dog . further examples illustrative of the vast many variations of designs possible which embody the disclosed invention are described with reference to fig9 and 11 . it will be understood in this context that other designs equally diverse in structure , and not shown by example , will fall within the embrace of the invention as contemplated . [ 0038 ] fig9 depicts a toy , generally designated 50 , which includes ropes 51 tensioned between a pair of opposed support members 52 ( retained to the supports by knots or other suitable means ). support members 52 are conveniently identical and are attached to one another end to end such that cup - shaped openings 52 a of the support members face in opposite directions . a handle 52 b is advantageously integrally molded as part of the support member , and serves as the animal restricted region . the ropes 51 , radially spaced from a central axis serve as the animal access regions . [ 0039 ] fig1 depicts a toy , generally designated 60 , which includes a handle 61 ( serving as the animal restricted region ) shrouded by a shielded portion 62 , and a ring portion 63 ( animal access region ), for typical access by a dog as shown . as with the previous embodiments , the toy 60 is made of suitable material of desired resiliency and weight . [ 0040 ] fig1 depicts a toy 70 , particularly suited for tug activities . in this embodiment , unlike the preceding embodiments , a handle 71 serving as the animal restricted region and shrouded by a shield 72 is disposed cross - wise to a central axis a ″″. a tug ring 73 for reception in a dog &# 39 ; s mouth , which serves as the animal access region , is disposed adjacent to the shield 72 , thereby allowing interactive tug play . in yet another embodiment , not depicted , a toy includes two regions each having a characteristic or more than one characteristic which , by virtue of a sensory response by the animal , creates a tendency for the animal to frequent one region more than another . in this regard , the characteristic in one region may be , for example , a taste preferred by the dog , and in the other region , one avoided , for example , a bitter flavor . in the alternative or in addition , smell , color , etc . may be used to discourage the dog to access an animal restricted region , and encourage access to the animal access region . in such dog toy , no particular configuration is important , and the toy may take , for example , the form of a simple rod , in which the animal access region is at one end portion and the animal restricted region on the other . it is noted that the foregoing embodiments described above herein merely represent a few of the myriad possible structural configurations which can embody the principles of the invention . in this regard , rather than being limited to specific structural arrangements and shapes , the intended scope of the invention contemplates design of any number of toys of desired shapes and sizes which take into account any of various parameters ascertained , at present of in the future , as contributing to the likelihood that an animal will frequent one region of toy more than another . in addition , it is further noted that other physical characteristics , in addition to those described specifically herein which exist at present or are discovered in the future as affecting animal behavior without harmful effect , may be suitably incorporated in a toy design practiced in accordance with the invention to influence an animal &# 39 ; s proclivity to access one region ( animal access region ) as opposed to another ( animal restricted region ), and the employment of such physical characteristics in alternative toy designs is contemplated to fall within the intended scope of the claimed invention . having described preferred embodiments of the invention with reference to the accompanying drawings , it is to be understood that the invention is not limited to those precise embodiments , and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims .
an animal toy includes structure presenting regions having characteristics providing different degrees of animal interest and / or accessibility , such that there is a higher likelihood that a dog will retain a particular part of the toy in its mouth apart from another region intended for grasping by the owner . the toy finds application in various modes of play , including tug activities between dog and owner , throwing and retrieval , and any other type of interaction in which the toy is held by the dog in its mouth and is thereby subjected to a depositing of saliva over the particular involved region of the toy . an embodiment includes members which include animal access regions and which are disposed in circumferentially spaced apart positions about a toy axis and radially spaced apart therefrom , and at least partially shielded handles , portions of which are positioned radially inward of a outermost radial extent of said members . exposure to saliva by a user is reduced by avoided contact with the region accessed to a greater degree by the animal during play .
