Abstract
A dynamic collapsible and revolving toy includes a base with a gear seat fixedly disposed inside. A gear plate mounted on the gear seat is driven to rotate by a gearbox with a power outputting gear through engagements of a transmission gear, a reduction gear and an internal gear. There are an interior tube set and an exterior tube set disposed above the gear plate and protruded out the base. The innermost tube of the exterior tube set is connected to the innermost tube of the interior tube set and the outermost tube of the exterior tube set is mounted on the gear plate. Further a retractable strip coiled on the ring slot of the gear plate is connected to the innermost tube so that the interior tube set and the exterior tube set can rotate upon the gear plate. A plurality of collars are mounted outside the exterior tube set for hanging decorative articles. A control circuit inside the gear seat makes the gearbox capable of providing the clockwise or counter-clockwise and accelerated or decelerated rotation. When a switch located on the base is pushed, a built-in IC program of the control circuit will then control the gearbox to output rotating power for extending/retracting the interior tube set, exterior tube set and the collar set from/to the base.

2. Description of Related Art




Frequent exchanges of culture and folk custom happen between countries along with the improvement of technology in transportation. Many festivals and occasions have become common holidays to be celebrated by many countries, such as Christmas, Valentine's Day and Mother's Day, etc. For celebration, various toys and gifts would be found in the market, but most of them are static displaying for viewing enjoyment. We see very little dynamic toys and gifts. Applicant therefore filed an application of U.S. patent application Ser. No. 09/488,523 on Jan. 21, 2000, entitled “Dynamic collapsible rotating toy” as attached. It disclosed a toy having the structure including an interior sleeve set


20


and an exterior sleeve set


30


that are installed at the center inside a base


10


. The interior sleeve set


20


has a winding strip and driven by an extension/retraction driving motor


50


. The exterior sleeve set


30


covers outside of the interior sleeve set


20


, of which innermost sleeve


31


is linked to the innermost sleeve


21


of the interior sleeve set


20


so that can execute extending and retracting functions when driven by the motor


50


. On the upper rim of each sleeve of the exterior sleeve set


30


are inserted a decorative article (such as Christmas tree leaves)


32


fitted to the toy (such as Christmas tree). The outermost sleeve


33


links with a gear


34


which is toothed with and driven by a rotation driving motor


60


through a reduction gear


61


. When a user turns on the power switch


13


on one side of the base


10


, the extension/retraction driving motor


50


is started to drive a winding strip


40


to push the interior and exterior sleeve sets


20


and


30


out from the base


10


so that they can extrude right above the base


10


. The gear


34


then on the base of the exterior sleeve set


30


touches and activates a first micro switch


70


located on one side of the sleeve set, thereby activating the rotation driving motor


60


. Therefore, on one hand, it controls the reduction gear


61


to drive the exterior sleeve set


30


to rotate slowly, while on the other hand, it drives the control circuit installed inside the base


10


to play melodious music and flash the LED lamps


36


hanging on the decorative article


32


. When the user turns on another operating switch


14


, it will turn off the music and LED


36


, and drive the extension/retraction driving motor


50


to turn in a reverse direction, then the extended interior and exterior sleeve sets


20


and


30


will be retracted into the base


10


, until after the gear


34


on the base of the exterior sleeve set


30


touches another second micro switch


71


, it will automatically cut off power and restore to its idle status. Though the operation of the above-mentioned toy is quite easy and convenient and the movement is fun and smooth, the structure is somewhat complicated when manufacturing. Especially, it uses two driving motors that increase the cost. It should be enhanced to be more competitive.

DETAILED DESCRIPTION OF THE INVENTION




Referring to

FIGS. 1

to


4


, the structure of the present invention includes a base


10


which a gear seat


20


is fixedly disposed inside. A gearbox


30


with a power outputting gear


31


located above the gear seat


20


is disposed below the gear seat


20


. The power outputting gear


31


engages to a central transmission gear


32


which three reduction gears


33


are engaged separately. Further there is an internal gear


34


engaged all the reduction gears and connected to a gear plate


40


. The gear plate


40


with a ring slot


41


is rotatably mounted on the gear seat


20


; therefore, under the engagements of gears


31


,


32


,


33


and


34


covered by the gear plate


40


, the gear plate


40


can be driven to rotate by the gearbox


30


. Furthermore, an interior tube set


50


and an exterior tube set


60


are disposed above the gear plate


40


and protruded out the base


10


. The interior tube set


50


is combined by a plurality of hollow tubes, such as three tubes in present embodiment. Similarly, the exterior tube set


60


is combined by three hollow tubes to cover outside the interior tube set


50


. The connection between the tubes of the exterior tube set


60


is shown in

FIG. 4

that can lead the tubes to be positioned and rotate together by the engagement of an extrusion


62


with a groove


61


. The innermost tube


63


of the exterior tube set


60


is connected to the innermost tube


51


of the interior tube set


50


. The outermost tube


64


of the exterior tube set


60


is then fixedly mounted on the gear plate


40


. There is a flexible retractable strip


42


coiled on the ring slot


42


of the gear plate


40


. The free end of the strip


42


connects to distal end of the innermost tube


51


through the hollow tubes of the interior tube set


50


. Further a collar set


70


, such as having eight collars in present embodiment, are disposed outside the exterior tube set


60


. The uppermost collar


71


of the collar set


70


is connected to the innermost tube


63


and the lowermost collar


72


is located on the gear plate


40


. It provides isometric connection between two collars by at least two ropes, that is, 180 degrees for two-roped connection between two ropes and 120 degrees for three-roped connection. As such, the rotation of the gear plate


40


can make the interior tube set


50


, the exterior tube set


60


and the collar set


70


have a horizontal rotation and further lead the strip


42


to make them have a vertical extension/retraction from/to the base


10


according to the rotating orientation of the power outputting gear


31


. A suitable decorative article


74


, such as Christmas tree leaves for a collapsible Christmas tree, can be decorated on the collars of the collar set


70


. Finally, a battery room


11


and a control circuit


12


are disposed inside the base. The control circuit


12


is connected to the gearbox


30


and the battery room


11


with batteries so that when pushing a switch


13


it can start the whole activation of the toy. The control circuit


12


is designed with different IC program depending on the topic, variety or purpose of the toy, capable of controlling the power outputting gear


31


of the gearbox


30


with clockwise/counter-clockwise and faster/slower rotation.




According to the above-mentioned structure, the present invention is idle as shown in FIG.


2


. The interior tube set


50


, the exterior tube set


60


and the collar set


70


are retracted together. It shows the toy is a small and not grow-up Christmas tree. When the switch


13


is pushed, the control circuit


12


actuates the power outputting gear


31


of the gearbox


30


rotating. The sequential engagements of the power outputting gear


31


, the central transmission gear


32


, the reduction gear


33


and the internal gear


34


make the gear plate


40


connected with the internal gear


34


rotate. There are two actions happened while the gear plate


40


is rotating. One is the exterior tube set


60


in connection to the gear plate


40


is rotated by the engagement of the groove


61


and the extrusion


62


. The other is the strip


42


coiled on the ring slot


41


is pulled out to drive the connections of the innermost tube


51


,


63


and collar


71


raising up. Such that the tubes of the interior tube set


50


and the exterior tube set


60


and further the collars of the collar set


70


are raised up one by one until they are fully extended as shown in FIG.


1


. During the operation, one can see a small Christmas growing up continuously and thereafter even still rotating until the switch


13


is again pushed. The control circuit


12


can also include music function to play melody and lamps are added on the leaves to have celebrating and amusing pleasure. When the switch


13


is again pushed, the control circuit


12


actuates the power outputting gear


31


of the gearbox


30


rotating inversely. Similarly, due to the engagements of the power outputting gear


31


, the central transmission gear


32


, the reduction gear


33


and the internal gear


34


, the gear plate


40


is rotated inversely. Such that, the strip


42


is wound to retract all interior tube set


50


, exterior tube set


60


and collar set


70


. The toy tree is then again a small and not grow-up one. It can depend on the IC program design of the control circuit


12


to stop the rotation of the tree or still have rotation before the switch


13


is once again pushed.




Furthermore, without changing the basic structure, the appearance of the invention can be properly modified or revised to represent different themes. For example, the collar set


70


can be formed as a multi-layered cake, and the base


10


can be as a cake box, then the invention can be a birthday present. Another, the collar set


30


can be formed to show a Paris Eiffel Tower, then the invention will become a dynamic decorative item presenting multiple themes with excellent application. Summing up, the structure of the present invention is easy and can use only one motor inside the gearbox


30


. That is, it is easy for assembly and is more competitive and economical in market.




The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
