comprises a first scene


12


contained within a transparent enclosure


14


, a second scene


16


exposed for direct viewing through a plurality of windows like window


17


in base


18


. On either side of window


17


the base


18


comprises supports or columns


20


,


22


. An upper platform


24


and a lower platform


26


complete the base


18


.




The decorative display device


10


further comprises a wind-up drive means


28


(see

FIGS. 2 and 3

) having a grippable knob


30


and a first output shaft


32


which may be interconnected to the scenes


12


,


16


as will be described more completely hereinafter. Music is provided to the decorative display


10


by way of a music producing means such as a music box


48


which is combined with and forms part of the wind-up drive means


28


as will be explained below.




It will be apparent to those skilled in the art that various modifications and variations can be made in the construction and configuration of the present invention, without departing from the scope or spirit of the invention. For example, the drive means


28


may be a battery or electrically operated drive means. Thus, it is intended that the present invention cover the modifications and variations of the invention provided they come within the scope of the appended claims and their equivalents.




The decorative display device


10


is preferably arranged so that the first and second scenes


12


,


16


, respectively, are placed one above the other to form a tier, thereby placing both scenes in the same field-of-view of an individual. Each of the upper and lower scenes


12


and


16


, respectively, may be drivenly connected to the drive means


28


which causes a rotation so that each scene appears to be in synchronization with the music or melody produced by the music box


48


. Rotating, music-synchronized scenes are aesthetically pleasing, and thus, provide a more interesting display relative to known decorative display devices. The scenes


12


,


16


may rotate simultaneously and synchronously (at the same speed in the same direction), or may rotate simultaneously and asynchronously (at different speeds in the same or opposite direction), or one scene may rotate (in either direction) while the other scene remains stationary, or both scenes may remain stationary.




The first scene


12


, located on the upper tier of the decorative display device


10


, comprises a plurality of figurines


12




1


,


12




2


. . .


12




η


, each of which are preferable formed of a well-known polymeric (or similar) materials and all of which are merged or blended into one integrated decorative scene, such as the family scene illustrated in

FIG. 1

commonly associated with holidays such as Christmas.




The enclosure


14


may be formed of glass or other suitable transparent material, such as plastic. The transparent enclosure


14


may be of any desired shape but preferably has the shape of a globe with a flat bottom portion on which a base


34


of scene


12


of the integrated figurines


12




1


,


12




2


. . .


12




η


, is mounted. The transparent enclosure


14


is preferably sealed and is filled with an appropriate transparent liquid


36


, such as water or an oil base liquid to achieve different aesthetic effects. The liquid


36


may have immersed therein small particles


38


of a selectable color, such as white, which simulates snow flowing or moving within the liquid, so that manual agitation of the decorative display device


10


causes a temporary suspension of the particles


38


in the liquid


36


. When the decorative display device


10


is placed on a support surface, the particles


38


slowly settle onto the figurines


12




1


,


12




2


. . .


12




η


, thereby simulating falling snow.




The second scene


16


, located on the lower tier of the decorative display device


10


, comprises a plurality of figurines


16




1


,


16




2


. . .


16




η


, all preferably of a well-known polymeric (or similar) material and all merged into an integrated decorative scene, such as a pile of toys and holiday related items illustrated in FIG.


1


and commonly associated with a gift giving holiday such as Christmas. It is preferred that the designs of scenes


12


,


16


be either complementary or contrasting relative to each other so as to enhance the noticeability and aesthetic effects imparted to a viewer thereof. Although scenes


12


,


16


are both related to Christmas, it is to be recognized that other festive events may be depicted by the scenes


12


,


16


in the practice of this invention.




The base


18


is preferably made of a metallic material and may have an ornamental design, as shown in

FIG. 1

, which provides for a blending aesthetic effect between the upper and lower scenes


12


,


16


of the decorative display device


10


. The base


18


has its lower platform


26


resting on legs


40


which serve a support function to provide support for the decorative display device


10


. The lower platform


26


also serves a particular support function, which will be described with reference to FIG.


2


.




The lower platform


26


has a circumferentially inwardly extending portion


26


A to which the base


18


is attached by means of fastening means such as screws


42


. The lower platform


26


supports the drive means


28


which is attached by fastening means such as screws


44


to the lower platform


26


. The drive means


28


also comprises an upwardly extending member


46


which supports a drum


47


(with outwardly extending prongs arranged in a predetermined array) on a first end, which drum


47


forms part of the music box


48


. The music box


48


is connected (at a second end) to a gear box mechanism


50


by means of a gear


52


. The gear box mechanism


50


may comprise a coil spring


98


, as shown in

FIGS. 5 and 6

, that is placed into tension by the rotation of the grippable know


30


. When the grippable knob


30


is relaxed, the coil spring unwinds and imparts a corresponding rotation to the output shaft


32


having a lower portion


32


A surrounding an upper portion


32


B




The present invention is not limited to a decorative display device having a second scene


16


positioned beneath the first scene


12


; rather the second scene


16


may be vertically spaced from the first scene


12


and may extend beyond the base


18


, as shown, for example in FIG.


7


. In the embodiment disclosed in

FIG. 7

, the second scene


161


extends beyond the outer periphery of the base


18


such that the second scene


161


may resolve around the base


18


. As shown in

FIG. 7

, the drive shaft drives into rotation a series of gears


162


. The series of gears


162


meshes with second scene


161


such that the rotation of series of gears


161


drives second scene


161


into rotation.




Other arrangements are considered to be within the scope of the present invention including revolving scenes that are located outside the outer periphery of the base


18


in combination with revolving scenes located within the base


18


.




In an embodiment of the present invention, the lower portion


32


A of drive shaft


32


surrounds the upper portion


32


B and is interconnected to a plate


54


which, in turn, is attached to the base of the second scene


16


. This attachment may be effected in any known manner, such as by a thin layer of adhesive material


56


. The second scene


16


also has a base


58


which is attached to the plate


54


and supports scene


16


in its predetermined position. The rotation of the plate


54


(through the connection of the plate


54


to the outer (lower) portion


32


A of drive shaft


32


) causes the rotation of the scene


16


. The plate


54


, in cooperation with the adhesive materials


56


, serves as the means for mechanical coupling and for interconnecting the scene


16


to the output shaft


32


of the wind-up drive means


28


. The upper portion


32


B of the output shaft


32


passes through the scene


16


, preferably in a non-interfering manner, and exits vertically from the scene


16


by way of aperture


60


.




The upper portion


32


B of the output shaft


32


is connected to means


62


for magnetically coupling the base


34


of the scene


12


to the upper portion


32


B of the output shaft


32


, and to the drive means


28


. The means


62


for magnetically coupling comprises a first plate


62


A mechanically connected to the upward end of the upper portion


32


B of the output shaft


32


, a second plate


62


B mechanically connected to the base


34


of the scene


12


, and preferably seated within a downward facing recess in the base


34


as shown in

FIG. 2. A

mutual (magnetic) coupling path is created between the metallic (magnetized) plates


62


A and


62


B through the non-metallic platform


24


and a non-metallic base portion


64


of the transparent enclosure


14


. The base portion


64


of the transparent enclosure


14


is physically separated from the base


34


of the scene


12


by a small gap


66


caused by the transparent liquid


36


to permit rotational movement of the scene


12


within the enclosure


14


. Such movement is provided by the fluid


36


within the enclosure


14


which substantially eliminates the coefficient of friction between the base


34


of scene


12


and the base portion


64


of the enclosure


14


.




The fluid


36


may be inserted into the enclosure


14


by way of an aperture (not shown) in the base portion


64


which is then sealed so that the fluid


36


remains within the sealed enclosure


14


without opportunity to evaporate or leak from the enclosure. The scene


12


within the sealed enclosure


14


is rotated because of the magnetic coupling means


62


although the base


34


, of the scene


12


is not mechanically connected to the output shaft


32


.




The drive means


28


provides the rotational rotational actuation of various components and will be described with particular reference to FIG.


3


.

FIG. 3

illustrates the drive means


28


as comprising a musical tine member


68


which contacts the pronged drum


47


and is preferably connected to the drive means


28


by way of screw members


70


and


72


. The drive means


28


further comprises intermeshing gears


52


,


74


,


76


,


78


all of which mesh so that the gear box mechanism


50


provides the impetus for moving the output shaft


32


of drive means


28


. Intermeshing gears


52


,


74


,


76


and


78


are connected to the music box


48


and a dissipation assembly comprising a fly-wheel


80


and a standing helical gear


79


which serve to slow the rotation of the shaft


32


. The output shaft


32


is positioned at the center of the decorative display device


10


so that the length of the shaft


32


extends along the vertical central axis of the display device


10


.




The pronged drum


47


, in cooperation with the tine element


68


, provides a melody sounding device (music box


48


) which allows for the drive means


28


to serve as a built-in source of music to accompany the revolving motion of scenes


12


and


16


. The drum


47


and the tine element


68


may be appropriately selected so as to provide various melodies, for example, a Christmas melody, to enhance the aesthetic effects of the rotating scenes


12


,


16


. Moreover, since the drum


47


and the musical tine element


68


are interconnected and activated by the gear box mechanism


50


, which can also activate the revolving motion of scenes


12


,


16


, the scenes


12


and


16


give the appearance to a viewer that the scenes


12


,


16


are in synchronization with the melody being played by the combination of the drum


47


and the musical tine element


68


.




The present invention is not limited to the above-described gear arrangement; rather the drive means


28


may be operatively connected to the scenes in such a manner so as to rotate either the first scene


12


or second scene


16


(for example, by a single gear). Additionally, the gear arrangement may be disposed around the central axis of the decorative display device.




As previously discussed, the scenes


12


,


16


may revolve or remain stationary with respect to each other. In one embodiment of the present invention, the first scene


12


is not connected to the output shaft


32


, but instead, is anchored firmly upon the upper platform


24


by means of an adhesive or other suitable mounting means. Similarly, in another embodiment of the present invention, the first scene is connected to the output shaft


32


, but the second scene


16


is anchored firmly upon the lower platform


26


in a similar manner. In these embodiments of the decorative display device


10


of the present invention, rotational motion is imparted to only the lower tier, i.e., the second scene


16


, while the upper tier, i.e., the first scene


12


remains stationary. Likewise, when the lower tier is fixed, the upper tier rotates. Such rotational motion may be in either direction, but only in one direction. In another embodiment of the present invention, as illustrated in

FIG. 4

, the scenes


12


,


16


of the decorative display device


10


may be rotated in the same direction and at the same speed. This is afforded by a coupling of the shaft segment


32


A and the shaft segment


32


B in the gear box


50


so that both shaft segments


32


A,


32


B rotate in the same direction at the same speed. Since the shaft segments


32


A,


32


B are arranged concentrically one about the other such coupling is easily accomplished by connecting the shaft segments


32


A,


32


B to the same gear or drive member. An alternate embodiment as illustrated in

FIG. 5

can impart different rotational speeds to each of the scenes


12


,


16


by varying the diameter of the drive or gear to which the shaft segments


32


A and


32


B are connected within the gear box


50


. The speeds will be proportional to the difference in the dimensional relationship of the respective gears or drive diameters.





FIG. 5

illustrates one option for gear box


50


which accomplishes the above-mentioned rotation. The gears within gear box


50


are configured to represent a speed altering means. The knob


30


, when rotated, winds or tightens the coil spring


98


. As the coil spring


98


unwinds it imparts rotational energy to bevel gear


78


which actuates the music box


48


and imparts rotational energy through bevel gear


86


and double bevel gear


88


which, in turn, imparts motion to bevel gear


90


. Bevel gear


90


is smaller in diameter than gear


78


which creates a different rotational velocity. Bevel gears


78


,


86


,


88


and


90


are mounted to the gear box frame


84


as described more fully below. Mounted directly to gear


78


is the upper drive shaft


32


B which runs through the center of bevel gear


90


. Lower drive shaft


32


A is attached directly to the upper surface of bevel gear


90


and is hollow to allow for upper shaft


32


B to pass through along its central axis.




Bevel gear


90


is seated in gear box frame


84


at its upper end. The upper end of bevel gear


90


is bent in an arc-like fashion to form a rotatable connector


94


. The rotatable connector


94


forms a cavity between the gear box frame


84


and the rotatable connector. Within this cavity is a lubricant


96


which will allow the upper end of bevel gear


90


to rotate upon the gear box frame


84


. The lubricant


96


can be liquid or mechanical such as a micro-ball bearing system.




It will be apparent to those skilled in the art that various modifications and variations can be made in the construction and configuration of the drive means and gear arrangement of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modification sand variations of the invention, provided they come within the scope of the appended claims and any other claim coverage afforded by applicable law.




Another embodiment of the decorative display device of the present invention imparts rotational motion that causes the scenes


12


,


16


to be revolved in different directions and at the same or different speeds. Opposite direction rotational motion can be accomplished by connecting the shaft segments


32


A and


32


B to different gears or drives which rotate within the gear box


50


in different and opposing directions. The present invention also provides a gear box configuration which serves as a means for imparting motion in a first and second direction to the upper and lower scenes.

FIG. 6

illustrates an example of this one gear box


50


option which will allow for rotation of the upper


12


and lower


16


scenes in the opposite direction at the same speed. In

FIG. 6

coil spring


98


is again connected to the lower surface of bevel gear


78


which imparts rotational energy to bevel gear


52


which actuates music box


48


. Bevel gear


52


also imparts rotational energy to bevel gear


90


. The result of this gear configuration is that upper scene


12


will rotate at nearly the same speed, (exact matching speeds being difficult to achieve due to mechanical losses), but in the opposite direction. The upper surface of bevel gear


90


is connected to the gear box frame


84


by means of the rotatable connector


94


described above. If the gears or drives are sized identically, then the speed which is imparted to the respective shaft segments


32


A,


32


B is the same. The upper and lower scenes


12


and


16


can have opposite motion at different speeds. It is clear from the drawings that the addition of one more gear can be used to vary the speed of one of the scenes based on diameters and inevitable mechanical losses. If the gears or drives have dissimilar diameters, then the speed which will be imparted to the shaft segments


32


A,


32


B will be different and in proportion to the dimensional relationship of the respective gear or drive diameters.




Another embodiment, which has been partially described above and is illustrated in

FIG. 5

, imparts rotational motion to only the upper tier, i.e., the first scene


12


, of the decorative display device


10


with the lower tier, i.e., the second scene


16


, remaining stationary. In this embodiment the shaft segment


32


B is connected to a drive or gear within gear box


50


and the shaft segment


32


A is mounted to the case of the gear box


56


and remains static. In all of the recited embodiments where rotational motion is imparted to either or both scenes


12


,


16


, the motion is accompanied by the playing of the music box mechanism


48


so that the motion of the scenes


12


,


16


is viewed while hearing the tones generated by the music box mechanism


48


.




In operation, the revolving of the first scene


12


and second scene


16


is initiated by the rotational winding of the grippable knob


30


which, in turn, causes the coil spring (not shown) of the gear box mechanism


50


to be placed into tension. When the grippable know


30


is relaxed, the coil spring unwinds and imparts rotation to the output shaft


32


(either or both shaft segments


32


A,


32


B) which, in turn, imparts a corresponding rotational motion to either or both the plate


54


and the magnetic coupling means


62


. For the embodiments of the decorative display device


10


of the present invention the rotation of scenes


12


and


16


provide for a noticeable and aesthetic effect to a viewer. Further, the upper tier scene


12


and the lower tier scene


16


, positioned at different vertical levels, are both within the same field-of-view and, thus, further attract the attention of a viewer, so as to further enhance the aesthetic effect provided by the decorative display device


10


of

FIGS. 1-3

.
