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.

axial cores.
(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.

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

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.

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

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.
