3 , in one preferred embodiment of the invention the head portion 14 is a generally life - like , three - dimensional representation of a bird head . head portion 14 may be a molded part and manufactured , for example , utilizing known injection molding or other molding technologies . as illustrated in fig4 , the head portion includes a cavity 30 through which a cord or rope 32 passes . the cavity 30 may include regions of differing dimensions , such as illustrated , so that rope 32 may pass through one portion of the cavity 30 and be secured , by a knot or other enlargement , at a second portion of the cavity 30 . in the illustrated embodiment , a knot 34 is formed at one end of the rope 32 and is secured within the cavity 30 . as illustrated , the other end of the rope 32 passes through an aperture 33 at a forward end of the head portion 14 , i . e ., the bill region of the fowl head . in other embodiments , a variety of different rope 32 securing approaches would be practicable . for example , the rope 32 may be secured on the top or bottom surfaces of the head portion 14 away from the forward - most edge . furthermore , the rope 32 may be secured to the head portion 14 in a variety of different approaches , such as mechanical , thermal and adhesive connections . for example , rope 32 may be crimped within or upon head portion 14 by a deformable mechanical fastener . in another example , rope 32 may be adhered via an adhesive , such as a flexible epoxy or silicon upon or within the head portion 14 . opposite the forward edge of the head portion 14 , a slotted structure 38 is defined . slotted structure 38 is preferably adapted to receive a flattened end portion 39 of body portion 12 . body portion 12 is connected to head portion 14 proximate to the slotted structure 38 via a connection structure , which in this example is a threaded fastener assembly 40 . the connection structure is defined between the head portion 14 and the body portion 12 . in the illustrated embodiments , the connection structure includes a threaded fastener 40 sized to be received into and engage portions of the head and body portions 14 , 12 . fastener 40 includes male and female components , numbered 42 and 44 , respectively . female component 44 includes a slotted end and an exterior , generally cylindrical surface 46 adapted to engage interior surfaces of an aperture 48 at the end of head portion 14 and surfaces of the grommet 16 . in a preferred embodiment , fastener 40 allows generally free movement between the head and body portions 14 , 12 , so that as the training device falls toward the ground the head and body portions can flutter or flap in a manner at least somewhat representative of an injured bird . the connection structure may assume a variety of different devices or structures , such as rivets , ropes , pins , fabric , adhesives , etc . one illustrative alternative embodiment is shown in fig1 b , where the head and body are connected by rope 32 within a neck region 50 . in this embodiment the rope can either extend out from the head portion 14 or between the body portion 12 and the head portion 14 . in preferred embodiments , the connection structure allows the head and body portions 14 , 12 to move relative to each other , preferably in a generally free and unrestrained manner . in other preferred embodiments of the invention , wing portions can be provided which may be generally flat in comparison to the cylindrical body portion 12 . wing portions can each be defined by a pair of fabric elements which are sewn or joined together utilizing known fabric connecting technologies . wing portions are preferably easily flexible and flutter during descent of the device 10 to mimic the wings of a compromised waterfowl . wing portions may include a stiffening element , such as cloth or other fabric , plastic , etc . the wing portions may be generally triangular in form and extend at a rearwardly directed angle relative to the body portion 12 . wing portions may be shorter in length than the overall length of body portion 12 . wing portions can preferably be permanently sewn or joined to body portion 12 . in one embodiment , wing portions and body portion 12 are defined by similar fabric elements , such as canvas or another heavy duty fabric . body portion 12 of the device is preferably unitary , i . e ., either formed of or formed into a material that remains substantially intact in the course of repeated use . such material is also durable in that it is able to withstand the rigors of being repeatedly thrown and retrieved . head portion 14 can also be attached to body portion 12 by a flexible cord , rope or other flexible connection . the head portion 14 of a device of the present invention is preferably constructed of a durable material , and positioned on the body portion to provide the drooped appearance of a downed waterfowl . the head is preferably configured to provide the appearance of a drooped waterfowl head , and attached to the body portion in a manner that allows the head to rotate freely in an axis about the central axis of the body , but that nevertheless retains the head in close proximity to the body portion . head portion 14 may comprised of fabric elements which are sewn together . head portion 14 may be of an injection molded plastic construction . head portion 14 may include stuffing materials to provide a life - like three dimensional portrayal of a bird head . also disclosed is a method of training a dog comprising the steps of ( a ) providing a training device as described herein , and ( b ) throwing the device to a distant location to be retrieved by the dog . those skilled in the art of training retrieving dogs will , given the present description , appreciate the manner in which devices of the present invention can be used . in a preferred embodiment , the device is generally thrown a sufficient distance from the dog to be trained , preferably onto the surface of field or body of water . alternatively , the device 10 may be thrown into a wetland area , containing cattails for example , or into an area covered with brush and / or trees . head portions 14 or wing portions of the device 10 may be caught upon brush or vegetation so that the device 10 is suspended away from the ground surface . in this regard , a more realistic presentation for training purposes is provided . generally , the device 10 will be tossed or thrown by the trainer , and the dog provided with a signal to begin to retrieve the dummy . the dog will retrieve the dummy , grasping it in the proper location and manner , and return it to the trainer . although the present invention and its advantages have been described in detail , it should be understood that various changes , substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims . moreover , the scope of the present application is not intended to be limited to the particular embodiments of the process , machine , manufacture , composition of matter , means , methods and steps described in the specification . as one of ordinary skill in the art will readily appreciate from the disclosure of the present invention , processes , machines , manufacture , compositions of matter , means , methods , or steps , presently existing or later to be developed that perform substantially the same function or achieve substantially the same result as the corresponding embodiments described herein may be utilized according to the present invention . accordingly , the appended claims are intended to include within their scope such processes , machines , manufacture , compositions of matter , means , methods , or steps .
a dog training device and method for training a dog to retrieve a downed fowl . the training device includes a head and a body . the head is moveably connected to the body such that the head moves similar to the way the head of an injured fowl moves . depending on the configuration , this connection can allow the head to move up and down relative to the body , or it can allow the head to move in all directions . the training device also includes a rope or other device such that a trainer can throw the device into the air for the dog to track and retrieve .
