1. F~eld o~ the ~n~ention .-~hR p~esent in~ent~on relates to an ~lectrically-dr~ven movable decorat~on de~igned im~tatlng ~he shapes of the ~ mals and the 1~ ke .
. i 2...... ... Description of the Pror Art 10. Recentiy, the movable decoration.characterized by compri~i~g.a base, a rotary axial core cur~ed in the middle and extendi~g from a base and an arti~icial flower with a hollo~ stem whe~einto said axial core is inser~ed 60 ~hat said artificial flower is caused to make the swinging motion ~y ~he rotary motion o~ sa~d rotary axial core ha~
been .p~opo~ed and practiced. Such a movablQ decoration compr~sing a single rotary core, howover, is ~uited for the upr~ght decoration such as those imitating the shapes of . the human body or the ~lowers but not suited for the dècorations imitating the four-footed an~mals and the imag~nary monstrous beasts, sinc~ the use o~ the single rotary axial core not only makes the app~arance of said models o~ the four-footed animals or the beasts unnatural 2~1~5~ ;

but also makes such models unable to ma~e their peculiar movements. On the oth~r-hand, ~hen ~he plural numb~r of th~ rotary axial core~ are u~ed, this requires not only the larger drive power but al~o mote elaborate dr~ve mechanlsm.
s Thus, the us~ of the 2-aXis drive mechanism can be considered Even thls 2-axis drive mechanism, however, ha~
its own problems such a~ how to realiz~ th~ fine movement~
of the variou~ members o~ the bod~es o~ the variou-~ animals ~, !
~uch as the tails, wings, legs and 80 on.
The ob~ect of the present invent~on is to peopose a movable decoration built or composea with at least two axial core~ a~d capablo of not only presenting the natural appearance but algo realizing the movements peculiar to the animals and the imaglnary monstrous beast~.

SUMMA~Y OF THE INVENTI~N
In order to r2alize said object, the movable decoration according to the present invention ~8 characteriz~d by baving the shape o~ an animal or Rn lmdginary ~onstrouY beast, as well as by satis~ying the ~ollowing conditions:
ti) At leait two curved rotary axial cores as ~ultiple cores ext~nd respectively ~rom their common base.

(c) The body of said animal o~ monstrous beas~ is mounted on said at least two rotary ax~al core~.
~Functlons and ~f~ect~ o~ the Invention According to said arrangement, the head is mounted on one rotary axial core, and the body on at lea3t two rotary~
axial cores, so that the movable decoration itself will not rotate even the rotary axial core~ rotate, and the body can be s~pported stably. Then, the h~ad and the body move in re~pon8e to the movement of the rotary axial cores, and the front and hind legs and the tail also move in response to the movement of the head and the body. Also, the mechanism for openang and closing the mouth $n respon~e to the movement of he head can readily be formed, whereby the appea~ance can be kept natural.

DETil~D DESCR~P~I~N OF ~8~ PREFERRED ~MBODIMENT
The embodiments of the present invantion will be ¦ described in reference to the drawing~. .
~n Fig.lA,- ~ denotes the movable decoration. Thss movable decoratlon A eon~t~ of the body 1 of the movable decoration having the shape o~ a dinosaur and its skeletaI
structure and the base 2 to support the body 1 of said . . movable decoration.
. At least two curYed rotary axial cores 3 and 4, e.g.
j metal wires, extend respectively from a common base 2.
These rotary axial cores 3 and 4 as multiple cores are ' 15 arranged so as to be sotated by a drive unit installed in ¦ the base 2. These rotary axial cores 3 and 4 are loosely covered with the hollow members 41 and 42 wh~se ends are fixQd tb the ba~s 2 80 that said rotary axial cores are ;I pqrmitted to rotate freely in said hollow members 41 and ' 20 42. Thqse hollow members may not be provided, however, j depending on the cases. These rotary axial cores are I arranged so as to b~ rotated.simultaneously by the drive unit installed in the base 2. More particularly, as shown in ~igs.2 and 3, a piece of input axial core 5 as an input ' ~O.~i56 :
member and four piece~ of the gear6 a8 tbe output members are ~nstalled in the base 2 . ~he input axial core 5 has a year ~a ~ixed tbereto and a ~onnector 10 with cro-~-~-groove-shaped concaved portion f~Ed therein. Said gear 5a engages w~th the first output gea~ 65 tbe first output gear h with the second out~ut qear 7, and the second outDut aear with the third and the fourth outDut aears 8 and 9. Then, a polygonal concave 15 is for~ad $n .the center of the top of the each o~ the four output gear~. A conn~cto~ 16.is fixed to the lower end of sald two rotary axial cores 3 and :: 4, and said connector 16 is re~ovably linked with the concave 15 of said output gears 8 and 9 respectlvel~.
The base 2 contains a pow~r source battery 11, ~ ~ound ...:
:~ sensor switch 17 and a motor 18 to be controlled by the sound sensed by said sound sensor switch 17, and a ~, cross-3haped projecting connector 20 formed on the front end of the outp~t ~haft 19 linked to the motor 18 through the gear unit is removably linked to the connector 1.0 of said inpUt gear ~a.

The arrangement wherein the motor 18 engages with a gear meshing with one of the gears 51a, 6, 7, 8 and 9 through a multistaqe reduction gear t~ain may be used.
As shown in ~ig.4 for the drive circuit diagram, said ~otor 18 1~ actuated when the power switch 40 is turned on 25~ :

and t~e senso~ ~witch 17 ~enseg the sound~ and the rotary power of the mo~or 18 is transmi~ted to the output axi~ 19 and then to the input gear 5a to cau~e the input gear 5a to be rotated, as well a-~ to s~multaneously cause the first ~hrough the fourth output gear~ 6 through 9 and the rotary axial cores 3 and 4 to rotate.
In the body 1 of the ~ovable decoration, the neck 21 I o~ th~ dinosaur shown In Fig ,lA con~istg of a coil-spring-like flexible hollow member; the head 22 is . 10 ~ixed to th~ front end of said flexible hollow member~ and the rear end of said flexible hollow member i8 connected to ~he che~t o the dinosaur. The lower jaw 24 is held by a supporting axi3 25 so as to be permit to move up and down.
Also, a connecting member 26 pro~ects rearward from the base o~ the lo~er ~aw 24 and formed so that the front end o~ 8a~ d co~necting member comes into contact with the neck 21. Further, the trunk 28 between the chest 23 and the hip 27 cons1~ts o~ the coil-spring-like elastic member 43 and the plural ~umber of bone-like member~ which are connected ., serially. ~he portion of the body ranging from the hip 27 to the tail 30 ~g also composed of the coil-sprin~-like members.
~ one of the rotary axial cores on the base 2, which is ``~ the ~otary axlal core 3, is inserted f.eely into the neck ~ 25 to~ether with the hollow member. ~he front end of sasd ,~ , '' .

rot.ary axial cor~ 3 $~ in3erted freely into a hole 31 of ~e head ~2. The rotary axial core 3 is inserted diagonally into the head 22~ An in~rtion hole 44 i8 ~ormed directly in the cbest 23 to p~rmit.the free . 5 insertion of th~ rotary axial cor~ 3 togethe.r w$th the .. hollow member 41. ~he chest 2~ ~ 8 s~pported upwardly by a stopper member 45 which is mounted rather tightly on the . hollow menb~r 41. Or the che~t 23 itsel~ may be mounted rather tightly on ~he hollow member 41. ~urther, the insertion holes 32 are formed in both the top and the bottom of the hip 27 to per~it the free insertion of both .
the other rotary axial. core 4 and the hollow member 41.
The ~ront legs 33 and the hind legs 34 are di~posed so as ~ to be able to move freeiy to the trunk 28.
i 15 In the above-described composition, the sound sensed by the sound sen~or switch 17 causes both the rotary axial cores 3 and 4 to rotate, but, since said rotary axial cores are curved partially, the curved portions of said cores swing respectively as the cores rotate. The body 1 of the movable decoration is supported with the rotary axial cores 3 and 4 through the hollow m~mbers 41 and 42 (the body l is ~, .upported d~rectly with two rotary axial cores 3 and 4 e~en if th~ hollow members are ibsent), so that the body l is caused to move as the body is swung bac~ and forth and lat~rally as th~ rotary axial cores :~

2~1~556 3 and 4 rotate r~spectively. Such moYemen~ of the body cau~eq the front legs 33, the hind legs 34 and the tall 30 to move respectively. 3esides, the front end of the rotary axial cor~ 3 i~ incl~n~d, so that t~e hea~ 22 is cauqed to s move up and down aQ ~he said incl~ned portion of the core rotatss. On the oth~r ha~d, the position of the connecting member 26 or the lo~er ~aw 24 remains unchanged, so that . . the point at which the connectina member 20 of the lower ~aw 24 comes in to contact with the neck 21 remains unchanged, and ne~ther does tbe inclination of the lower jaw 24. ThUs, the head ~2 and the lower jaw 24 are jointly .. move to cau~e the mouth to be opened and closed and the neck to be swung as ~hown in ~i g5 . lA and 18. In addition, the ela~tic member 43 o~ the trunk 28 c~n be either co~pressed o~ extended to qmoothly adapt to the movements o the rotary axial cores 3 and 4.
As Qhown in Fig.5, in the opening-and-closing mechanism o~ the mouth, the ba3e of the lower jaw 24 i~
supported with an axi~q to ~he head 22, and.another supporting axis 35 may be for~ed under ~or above) said supporting axis 25 to axially support the front end of the neck 21, a~ well a to permit the curved portion 3a o~ the rotary axial core 3 to be freely ~nserted into the through hole 36 of the neck 21. The rotation of the curved portion 3a causes the supporting axi-q 35 of the lower ~aw 24 to .

move back and forth, thereby causing th~ up and down movement o~ the lower ~aw 24 or the opening and closing of the mouth.
As shown in ~ig5 . 6 and 7~ the hollow member to constitute the neck may be formed by ~tacking the plural number o~ the blocks 37 with the cs~tral through holes res~ct~vely. Further, in this embod~ment, the trunk 28 i3 divided into thre~ portions; the front portion 28a i5 supported from underside with a sto~per 46 which is fitted rather tightly around the hollow member 41; the rear portion 28b is supported with the other rotary axial core 4 by having said rear portion supported from underside with the ~lange 47 80 that the front end o the rotary axial core 4 is projected into an ell$ptical hole 47 to serve a3 a guide7 and the middle portion ~8c including tbe tail 30 passes through a circular ring 38 80 as to be a~le to move back and forth. Thus, the distance between.the front legs 33 and the hind legs 34 varies, so that the length of tbe trunk 28 as the whole can be made to look eithet compressed or extended longitudinally. In th~s case, the apparent compression and extension o~ the trunk 28 can be realized even without uslng the elastic material.
As described above, the neck portion 21 o~ the dtnosaur is mountOd on one rotary axial core 3, whereas the trrnk 28 i~ mounted on the two rotary axial cores 3 and 4 .. , . , . - ~ :

through the hollow membQ~s 41 and 42, 80 that the body 1 remains unr~tated even when the rot~y axial cores 3 and rotate respect~vely. ~hen, the neck 21 and the trunk 28 are cau~ed to move in response to th~ rotation of the two 5 rotary axial core~ 3 and 4, and the ro~t legs 33, hind legs 34 and tail 30 move accord~ngly. ~lso, the mechan~Qm to open and close the mouth in response to the movement of the neck 21 ~an be forNed easily, and the natural appearance of the body can be realiz~d too.
The po~tion which comes into contact with the connecting member 26 may be arranged so that said connectin~ member comes into contact directly with the hollow member 41 or the rotary axial core 3 by eliminating the block 37.
Thi~ embodiment is concerned with the din~saur, but the model can be any other animals or the imaginary monstrous ~east~. Also, such model can be either tha~ o~
the skeletal structure or that covered with the skln.
~urther, the mutual degrees of the angles among the rotary axial core~ can be determined appropr~ately depending on the kind of animal. The numbee o~ the rotary axial cores may be more than three pieces ~n order to make the movement o~ the animal more elaborate.
