Description

TITLE OF THE INVENTION MOVABLE DECORATION

BACKGROUND OF THE INVENTION

This invention relates to a movable decoration of the centroid moving type, and more particularly to a movable decoration which is so constructed that the center of gravity of the decoration is moved.when it is actuated upon detection of predetermined external stimulus, to thereby cause the decoration to carry out unique and unexpected movement or motion while shifting its position.

Conventionally, a movable decoration is known which is constructed in such a manner that a flexible hollow cover member formed in imitation of any desired figure such as a flower or the like is loosely fitted on a revolving shaft or core rotatably supported on a bage and arranged so as to outward extend from the base, so that rotation of the revolving shaft may cause the hollow cover to be moved in a meandering manner, resulting in giving a viewer interest and surprise.

However, consumers constantly desire the appearance of a movable decoration exhibiting unique and unexpected movement which has never been seen.

Accordingly, it would be highly desirable to provide a movable decoration which is capable of accomplishing unique and unexpected movement or motion sufficient to give a viewer much interest and surprise.

SUMMARY OF THE INVENTION

Generally speaking, in accordance with the present invention, a movable decoration of the centroid moving type is provided. The movable decoration includes a drive circuit including a motor, a power supply and sensor means adapted to detect predetermined external stimulus and connected to the motor and power supply"so as to drive the motor through the power supply when the sensor means 1 detects the predetermined external stimulus; a base including an outward projecting curved bottom surface; centroid moving means movably arranged with respect to the base; a transmission mechanism operatively connected between the motor of the drive circuit and the centroid moving means to transmit the output of the motor to the centroid moving means to actuate it; and a decoration body loosely fitted on the centroid moving means so that the center of gravity of the decoration body may be moved due to actuation of the centroid moving means. The decoration body is connected to the base, resulting in the movable decoration carrying out pivotal movement about the outward projecting curved bottom surface of the base.

In the movable decoration of the centroid moving type of the present invention, as described above, the decoration body is loosely fitted on the centroid moving means so that the center of gravity of the decoration body may be moved due to actuation of the centroid moving means. Also, the decoration body is connected to the base to cause the movement of the center of gravity of the decoration body to be transmitted to the base including the outward extending curved bottom surface. Thus, the movable decoration of the present invention carries out pivotal movement about the bottom surface of the base while shifting its position on a support, resulting in exhibiting unique and unexpected movement sufficient to give a viewer much interest and surprise.

In accordance with the present invention, there is also provided a movable decoration of the centroid moving type comprising a base formed into a vessel like shape and including a convex bottom surface; a drive circuit arranged in the base and including a motor, a power supply and sensor means adapted to detect predetermined external stimulus and connected to the motor and power supply so as to drive the motor through the power supply when the sensor means detects external stimulus; a core rotatably supported i 1 on the base and arranged so as to outward extend therefrom; a drive mechanism arkanged in the base and operatively connected between the motor of the drive circuit and the core to transmit the output of the motor to the core to rotate it; and a decoration body formed into any desired figure and including a head. The decoration body is oosely fitted on the core so that the center of gravity of the decoration body may be moved due.to rotation of the core. The decoration body is connected to the base, resulting in the movement of the center of gravity of the decoration body causing the movable decoration to carry out pivotal movement aboit the convex bottom surface of the base whilelshifting its position. The head of the decoration body is formed with an opening in imitation of a mouth of the figure and provided with a spring, resulting in the opening being operated by the inertia of movement of the decoration body and the restoring force of the spring.

Accordingly, it is an object of the present invention to provide a movable decoration of the centroid moving type which is capable of accomplishing unique and unexpected motion due to movement of the center of gravity upon detection of predetermined external stimulus as well as keeping stationary when it does not detect the stimulus.

It is another object of the present invention to provide a movable decoration of the centroid moving type which is capable of causing its center of gravity to be moved to carry out unique and unexpected movement while shifting its position when it is actuated upon detection of predetermined external stimulus.

It is a further object of the present invention to provide a movable decoration of the centroid moving type which is capable of carrying out comical movement as well as unique and unexpected movement.

It is still another object of the present invention to provide a movable decoration of the centroid moving type which is capable of safely increasing the magnitude of 1 movement or motion of the decoration due to movement of the center of gravity.

It is yet another object of the present invention to provide a movable decoration of the centroid moving type which is capable of ensuring unexpected movement due to movement of the center of gravity without being damaged.

It is a still further object of the present invention to provide a movable decoration of the centroid moving type which is capable of carrying out unexpected movement due to movement of the center of gravity while preventing from falling down on a support and dropping therefrom.

It is a yet further object of the present invention to provide a movable decoration which is capable of increasing interest in its motion due to movement of the denter of gravity.

Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.

The invention accordingly comprises the features of -construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Now, a movable decoration of the centroid moving type according to the present invention will be described hereinafter with reference to the accompanying drawings.

Referring now to Fig. 1 showing an embodiment of a movable decoration ot the centroid moving type according to the present invention, a movable decoration of the embodiment generally indicated at reference numeral 20 may be generally formed in imitation of any desired figure. For example, it may be made in imitation of a creature such as a mankind, an animal, a plant or the like. Alternatively, it may be formed in imitation of a still life which is normally considered to be stationary. In the illustrated embodiment, it is generally formed in imitation of a bird. More specifically, the movable decoration 20 externally includes a base 22 formed in imitation of the waist of a bird and a hollow decoration body 24 supported on the base 22 and formed in imitation of the upper half of the bird. Alternatively, only the decoration body 24 may be formed in imitation of any desired figure. The decoration body 24 is loosely fitted on centroid moving means 26 arranged in a manner to be movable with respect to the base 22 and outward extend from the base 22 and adapted to move the center of gravity of the decoration body 24 when it is actuated. In the illustrated embodiment, the centroid moving means 26 comprises a core arranged in a manner to be rotatable with respect to the base 22 and upward extend from therefrom. Reference numeral 27 designates the feet of the bird.

The base 22 includes a curved bottom surface 28 formed into an outward projecting shape such as a convex shape. In the illustrated embodiment, the base 22 is formed into a shape like a vessel or container. However, it may be formed into any other suitable shape such as a dish-like shape or the like so far as it includes the outward projecting curved surface 28. In the base 22 is arranged a drive unit 29 which includes a drive circuit constructed as shown in Fig. 3 and arranged as shown in Figs. 4 to 8 and a transmission mechanism 30 constructed as shown in Figs. 4 to 10. The drive circuit and transmission -7mechanism 30 will be described more detailedly hereinafter.

The decoration body 24 includes a hollow member 32 made of a flexible material and formed in imitation of the trunk of the bird, an upper member 34 mounted on the distal or upper end of the hollow section 32 and formed in imitation of the head of the bird, and a plurality of plate- like members 36 formed in imitation of the wings of the bird and mounted on the hollow member 32. The hollow member 32 is securely connected at the proximal or lower end thereof to the base 22. In the illustrated embodiment, the lower end of the member 32 is fittedly mounted on a hollow boss 38 provided on an upper cover 40 of the base or vessel 22.

The centroid moving means or core 26 on which the decoration body 24 is loosely fitted may comprise a wire made of a bendable or flexible and shape-retaining material such as a metal wire and be generally bent in a meandering manner. The core 26 is supported at the lower end thereof in the base or vessel 22. Also, the core 26 is operatively connected at the lower end thereof to the transmission mechanism 30 arranged in the base 22.

The drive circuit of the drive unit 29, as shown in Fig. 3, generally includes sensor means 42 adapted to detect predetermined external stimulus, a power supply 44 such as a battery or the like, a main switch 46 and a motor 48 electrically connected to one another as shown in Fig. 3 so as to drive the motor 48 through the power supply 44 when the sensor means 42 detects the predetermined external stimulus while the main switch 46 is kept turned on. In the illustrated embodiment, the sensor means 42 may comprise a sound sensor switch adapted to detect sound of a predetermined level.or more. However, any other suitable sensor may be conveniently used for this purpose which is adapted to detect external stimulus other than sound such as infrared rays, light, heat, pressure, temperature, smoke or the like. The so-constructed drive circuit may be t -8received in the base or vessel 22 as shown in Figs. 4 to 8. Also, the sensor means4-1 and main switch 46 each are so arranged that a part thereof is exposed through the upper cover 40 of the base 22 and the power supply 44 is detachably received in the base 22.

The transmission mechanism 30 which is arranged in the base or vessel 22 is operatively connected between the motor 48 and the centroid moving means or core 26 to transmit the output of the motor 48 to the core 26, to thereby actuate or rotate-it. For this purpose, the transmission mechanism 30 may be constructed in such a manner as shown in Figs. 4 to 10. More particularly, the transmission-mechanism 30 is received in a casing 50 housed in the base or vessel 22 through cushioning members 52 positioned between the vessel 22 and the casing 50. The abovedescribed drive circuit may be arranged in the casing 50 as well. The casing 50 is substantially closed with a lid 54. The cushioning members 52 each are made of a material which permits the cushioning member to satisfactorily exhibit a sound absorbing effect sufficient to absorb sound generated due to actuation of the drive unit 29 and a shock absorbing effect sufficient to absorb impact possibly applied to the base 22, to thereby prevent malfunction and damage of the drive unit 29. The transmission mechanism 30 includes an output shaft 56 operatively connected to an output shaft 58 of the motor 48 through gears 60, 62, 64, 66, 68 and 70 in turn, whereby the output or driving force of the motor 48 is transmitted to the output shaft 56 of the mechanism 30. The upper end of the output shaft 56 has a hexagonal cross-section and is fitted into a hexagonal hole 72 of a joint 74 as shown in Figs. 9 and 10 for transmission of its torque. Thus, the output shaft 56 and joint 74 constitute a coupling in cooperation with each other. In the joint 74 is fixed the lower end of the core 26. The joint 74 is rotatably - 1 supported in a sleeve 76 of the casing 50. Thus, the core 1 f - 1 -g- 26 is rotated by the motor 48.

On the joint-74 is carried a socket 78 in a manner to be fixed against rotation with the joint 74. In the illustrated embodiment, the socket 78 is formed integral with the lid 54, as shown in Fig. 5. The core 26 is guided through the socket 78 to the joint 74. The hollow boss 38 on which the lower end of the hollow member 32 of the decoration body 24 is securely mounted is formed integral with the socket 78 in a manner to be positioned on the socket 78. Reference numeral 80 (Fig. 5) designates a holder for securely holding the fitted engagement between the upper end of the the socket 78 and the lower end of the core 26. Thus, the hollow member 32 of the decoration body 24 is securely fixed against rotation on actuation of the motor 48 while ensuring free rotation of the core 26. The holder 78 may be rigidly mounted on the upper cover 40 to a degree sufficient to permit the whole casing 50 to be outward drawn out of the vessel 22 while picking the holder 78. Reference numeral 82 designates cells constituting the power supply 44. - Now, the manner of operation of the movable decoration of the illustrated embodiment constructed as described above will be described.

1 The movable decoration 20 is placed on a support surface such as a floor,'a table or the like. Then, when the main switch 46 is turned on and the sound sensor switch 42 detects sound of a predetermined level or more, the motor 48 is driven. The driving force of the so-driven motor 48 is transmitted-from the output shaft of the motor 48 through the gears 60, 62, 64, 66, 68 and 70 and the output shaft 56 of the transmission mechanism 30 to the core 26. This causes the bent or curved core 26 to be rotated in the hollow member 32 of the decoration body 24, so that the decoration body 24 loosely fitted on the core 26 may be moved in a meandering manner depending upon the manner of bending of the core 26 with the rotation of the -10core 26 while being fixed against rotation, during which the center of gravit of the decoration body 24 is irregularly moved or changed, resulting in the movable decoration 20 continuing irregular pivotal movement about the curved or convex bottom surface 28 of the base 22 depending upon the movement of the cen.ter of gravity of the decoration body 24 while shifting its position on the support surface 84. Thus, it will be noted that the movable decoration of the centroid moving type of the illustrated embodiment carries out unique and unexpected movement sufficient to give a viewer much surprise and interest.

TLe- movable decoration of the centroid moving type of the illustrated embodiment may furi-her include anchor means generally at refezrnce numeral 84 in Figs.

1 and 2 and adapted to prevent the movable decoration from falling down on or dropping from the support surface 84 during the pivotal movement about the curved bottom surface 28 of the base 22 due to the movement of the center of gravity of the decoration body. In the illustrated embodiment, the anchor means 86 comprises a pair of chains 88 each connected at the proximal end thereof to each of connectors 90 provided on at least both upper sides of the base or vessel 22 and suckers 92 each mounted on the distal end of each-of the chains 88. The so-constructed anchor means 86 serves to limit the range of pivotal movement of the movable decoration 20, to thereby prevent it from falling down during the pivotal movement.

The upper member or head 34 of the decoration body 24 may be constructed as shown in Figs. 11 to 13. A head 34 of Figs. 11 to 13 includes an upper head section 96 and a lower head section 98 each formed of a synthetic resin material and connected at the rear portion thereof to each bther by means of a hinge 100. In the head 34 is arranged an elastic member 102 in a manner to vertically extend between the upper head member 96 and the lower head member A T -11 98. In the illustrated embodiment, the elastic member 102 comprises a coiled spring. The upper head section 96 is provided on the rear portion thereof with a support shaft d h eof on the upper 104, which is fixed at tW-- en _,t4er head section 96 and inserted at the V. 1 end thereof into the upper or distal end of the hollow member 32 of the decoration body 24, so that the head 34 may be irregularly pivotally moved about the support shaft 104 while the center of gravity of the decoration body is moved. Such pivotal movement of the head 34 causes the lower head section 98 to be pivotally moved about the hinge 100 with respect to the upper head section 96, resulting in operating as if the head 34 is repeatedly mouthed between the upper head section 96 and the lower head section 98, during which the elastic member 102 constantly exhibits elastic force in the direction of closing the mouth.

The head is provided with first and second engagements 106 and 108, which are arranged so as to be engaged with each other before the upper head section 96 and lower head section 98 are abutted against each other when the lower head section 98 is pivotally moved about the hinge 100 with respect to the upper head section 96, resulting in preventing the generation of noise due to the abutment between both head sections when the mouth is closed. For this purpose, in the illustrated embodiment, the first engagement 106 is provided at the portion of the hinge 100 associated with the upper head section 96 and the second engagement 108 is provided at the portion of the hinge 100 associated with the lower head section 98. Alternatively, the first and second engagements 106 and 108 may be provided at the upper and lower head sections 96 and 98 in a manner to be adjacent to the hinge 100. The upper and lower head sections 96 and 98, as shown in Figs. 11 and 12, are formed at the portions thereof opposite to each other with openings 110, respectively. Also, the upper and lower head sections 96 and 98 each are integrally provided -12on the inner surface thereof with a hook 112 in a manner to be opposite to the opening 110. The opening 110 is formed in view of the necessity of drawing a pattern for integrally forming the hook 112. On the hook 112 is held each end of the elastic member 102. The openings 110 is closed with a lid 114 formed as shown in Fig. 13. The lid 114 is formed on the lower surface thereof with a pair of legs 116 in a manner to downwardly extend therefrom and be spaced from each other. The legs 116 each are formed at the distal end thereof with a projection 118 engaged with the periphery of the opening 110 when the lid 114 is fitted in the opening 110. Also, the projection 118 is adapted to be positioned in proximity to the hook 112 when the lid 114 is fitted in the opening 110.

When the head 34 constructed as described above is repeatedly pivotally moved or shaken by actuation of the motor 48, the lower head section 98 is pivotally moved about the hinge 100 with respect to the upper head section 96, to thereby carry out movement as if the head 34 operates its mouth. When the mouth is to be closed, the first and second engagements 106 and 108 are engaged with each other before the upper and lower head sections 96 and 98 are abutted against each other, to thereby block the lower head section 98 from being further pivotally moved, resulting in effectively preventing the abutment or collision between both head section. Thus, the head is prevented from generating noise and being damaged during the movement. Also, the opening 110 of each of the head sections 96 and 98 is closed with the lid 114, to thereby prevent the whole appearance of the head 34 from being deteriorated. Further, the projection 118 of each of the legs 116 of the lid 114 are arranged so as to be positioned in proximity to the hook 112, so that the mouth of the head 34 may be smoothly operated because the projection 118 effectively prevents the end of the elastic member 102 from being released from the hook 112. The first and second N c 1 -13engagements 106 and 108 may be arranged on the outside of the head so far as they accomplish the above-described function.

The drive circuit of the drive unit 29 may be constructed as shown in Fig. 14. In a drive circuit of Fig. 14, when a sound sensor 42 detects sound of a predetermined level or more, it generates a detection s ignal, which is supplied through a junction J 6 to a transistor Q 3 to turn on it, so that transistors Q 2 and Q 1 are turned off and turned on, respectively, resulting in the signal being supplied through a junction J 3 When the supply of the signal from the sound sensor 42 is interrupted, the transistors Q 3P Q2 and Q 1 carry out reflecting operation to stop the supply of the signal from the junction 1 3 This causes a pulse signal of a width corresponding to the length of the sound detected to be output from the junction J 3 as shown in Fig. 15.

A clock pulse oscillator C is constituted by NAND gates UIa and UIb, a resistor R and a capacitor C The 6 0 4 clock pulse oscillator C outputs a clock pulse of f _%. 1Hz through an output terminal 120 thereof irrespective of a signal supplied from the junction J 3 Reference numeral 122 designates a signal control section which is constituted by NAND gates UIc and UId and a resistor R 17' to which the signals supplied through the junction J and 3 terminal 120 are input, resulting in alternately outputting two signals different in level through terminals 124 and 126 thereof, as shown in Fig. 15.

The drive circuit also includes a drive circuit section 33 for driving a motor 48, which includes a first pair of transistors Q 4 and Q5, a second pair of transistors Q6 and Q 7# and resistors R 101 R ill R 12 and R 13 In the soconstructed drive circuit section 33, when the two signals different in level are alternately supplied from the terminals 124 and 126 to the transistors Q 4 and Q 6# the. transistors Q 4 and Q 6 are alternately turned on and turned 1 -14off, so that the direction of a voltage of a signal accumulated in the motor 48 is shifted to cause the motor to alternately carry out normal rotation and reverse rotation.

Fig. 16 shows another embodiment of a movable decoration of the centroid moving type according to the present invention. A movable decoration of the illustrated embodiment includes centroid moving means or a core 26 which is arranged on a base 22 so as to upward extend therefrom, a decoration body 24 loosely fitted on the core 26 which is formed in imitation of a bird and at least one weight 130 mounted on the core 26 so as to be rotated with rotation of the core 26. Thus, the movable decoration of the embodiment, when the core 26 is rotated, causes the weight 130 to be rotated with the core to more facilitate movement of a center of gravity of the decoration body 24, resulting in giving a viewer more interest and surprise. The remaining part of the embodiment may be constructed in substantially the same manner as the above-described embodiment.

As can be seen from the foregoing, in the movable decoration of the centroid moving type of the present invention, the decoration body is loosely fitted on the centroid moving means so that the center of gravity of the decoration body may be moved due to actuation of the centroid moving means. Also, the decoration body is connected to the base to cause the movement of the center of gravity of the decoration body to be transmitted to the base including the outward extending curved bottom surface. Thus, the movable decoration of the present invention carries out pivotal movement about the bottom surface of the base, resulting in exhibiting unique and unexpected movement sufficient to give a viewer much interest and surprise.

It will thus be seen that the objects set forth above, among those made apparent from the preceding z 1 -15description, are efficiently attained and, since certain changes may be made in the above construction without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
