1. Field of the Invention
The present invention relates to an ornament assembly and a transmission mechanism used therein, in particular, to an ornament assembly having a plurality of movable decorative figurines, and further to a transmission mechanism used in the ornament assembly to drive the decorative figurines to convey a flying theme for and not limited to seasonal holidays.
2. Description of Related Art
It is known to provide an ornament assembly wherein several decorative figurines are respectively supported on rods from a base member, so that the decorative figures may be displayed and moved to provide an appearance that is associated with a particular season, or holiday.
The decorative figurines on the ornament assembly may be movable relative to another one. For example, various music box ornaments have been disclosed, and have appeared on the market. These ornamental display assemblies are rotated or reciprocated by the driving mechanism through a transmission mechanism. However, conventional transmission mechanisms for used with the music box ornaments are commonly complicated and occupied space. Besides, numbers of decorative figures are limited and hard to expand because of the structure of conventional transmission mechanisms. Furthermore, the conventional decorative figurines of the ornament assembly can not express a flying appearance, so that this type of ornament assembly gives little attraction to consumers.
In view of the aforementioned issues, the present invention provides an ornament assembly and a transmission mechanism used therein for the simplification of the transmission mechanism used in the ornament assembly. In addition, the transmission mechanism is provided with well expandable characteristics, which allows expanding the quantity of decorative figurines, and for decorative figurines to move in an expanding manner. Furthermore, our use of motions on seasonal decorative figurines of the ornament assembly creates a more vivid flying appearance.
To achieve the above-mentioned objectives, the present invention provides an ornament assembly used in an ornament assembly, which includes a base member, a motivating unit, a power module and a plurality of tappet rods. The base member has a plurality of receiving housings formed thereon. The motivating unit has a rotatory shaft crossed through the receiving housings and a plurality of eccentric wheels formed on the rotatory shaft. The eccentric wheels are received in the receiving housings respectively. The power module is connected to one end of the motivating unit. Each of the tappet rods has a follower member formed on a lower end thereof and movably contacted the eccentric wheels.

The decorative figurines are disposed on a top end of the tappet rods respectively.
The following beneficial effects according to the ornament assembly and transmission mechanism used therein of the present invention are described as follows. The transmission mechanism used in the ornament assembly is simplified. Furthermore, the present invention can easily expand the quantity of the movable decorative figurines, and the present invention can express a flying appearance with ascending/descending actions more vivid.
Still other aspects, features, and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description of embodiments constructed in accordance therewith, taken in conjunction with the accompanying drawings.

The base member 10 in this embodiment is a plate-shaped board, and has a plurality of receiving housings 12 which are formed on a top surface of the base member 10. To strength its structure, the base member 10 could be upwardly protruded a plurality of ribs 102 on a top side thereof.
In this embodiment, each of the receiving housings 12 further includes a lower housing 122 and an upper housing 121. The upper housing 121 could be mounted on the lower housing 122 by screws (not shown). The lower housing 122 could be integrally formed on the base member 10, and the material can be plastic, so that the base member 10 and the receiving housings 12 can be produced on a mass scale. The tappet rods 16 transversely pass through the upper housings 121.
The motivating unit 14 has a rotatory shaft 142 and a plurality of eccentric wheels 144 formed on the rotatory shaft 142 with intervals. The rotatory shaft 142 crosses through the receiving housings 12. The eccentric wheels 144 are received in the receiving housings 142 respectively. The eccentric wheels 144 could be integrally formed on the rotatory shaft 142.
The tappet rods 16 are used to support decorative figurines on the top ends respectively. Each of the tappet rods 16 has a follower member 162 which is formed on a lower end thereof and movably contacts the eccentric wheels 144. In this embodiment, the follower member 162 is plate shaped. The bottom surface of the follower member 162 contacts with the eccentric wheel 144. When the eccentric wheel 144 is driven and rotated, the follower member 162 follows a periphery of the eccentric wheel 144 to ascend and descend. Thereby, the tappet rods 16 can be moved upwardly/downwardly with the decorative figurines.
To limit the tappet rods 16 to move along the erect direction, each of the receiving housings 12 further includes a sleeve member 123. The sleeve member 123 is mounted on the upper housing 121 by screws (not shown). Each of the tapper rods 16 is slidably passed through the rod sleeves 123 respectively. Besides, in this embodiment, the tappet rods 16 includes a stroke portion 164 which is formed at a lower portion thereof and above the follower portion 162. The stroke portion 164 is slidably received in the sleeve member 123. The length of the stroke portion 164 is substantially equal to a depth of an inner space formed in the sleeve member 123, and the length of the stroke portion 164 is substantially longer or equal to a radial of the eccentric wheel 144. Therefore, the stoke portion 164 can reciprocate in the sleeve member 123.
The power module 18 is used to rotate the rotatory shaft 142 and is connected to one end of the motivating unit 14. In this embodiment, the power module 18 is mounted on the base member 10 and is adjacent to one of the outmost receiving housings 12. The power module 18 could be composed of a motor and several gears. The rotatory shaft 142 could be provided with a gear at one end thereof to engage with one gear of the power module 18, so that a power can be transmitted from the power module 18 to the motivating unit 14. Alternatively, the power module 18 could be a driving mechanism (clock-work) of a wind-up music box mechanism.

The scenery member 20, 20a, 20b, and 20c could be made of paper, so that it is easily to be changed by consumers themselves. Furthermore, those doll figurines could be movable, so that the consumers can move them. Therefore, the ornament assembly according to the present invention can provide more amusement for consumers.
The present invention has the advantages as follows.
1. The transmission mechanism used in the ornament assembly is simplified. The motivating unit 14 is simplified and formed integrally. The power module 18 is smaller than the conventional one and occupied a less space.
2. The present invention can easily expand the quantity of the movable decorative figurines, because the transmission mechanism provided can extend the rotatory shaft 142 easily with more eccentric wheels 144.
3. The present invention can express a flying appearance with ascending/descending actions more vivid. Through the flexible portion 168, it could provide a waving and tremble appearance for these decorative figurines 23, 24, 25. Therefore, the ornament assembly of the present invention can give more attraction to consumers.
The above-mentioned descriptions represent merely the preferred embodiment of the present invention, without any intention to limit the scope of the present invention thereto. Various equivalent changes, alternations or modifications based on the claims of present invention are all consequently viewed as being embraced by the scope of the present invention.
