The driven wheel 25 of the driving device 2 is disposed above the drive wheel 23. The support bar 27 of the driving device 2 is formed on and extended outward from a side of the driven wheel 25. Each of the torsion springs 28 has a substantially V-shaped profile.

The decorative unit 3 is mounted on the support bar 27 of the driving device 2. In the preferred embodiment of the present invention, the decorative unit 3 includes a decorative body 31, a fixing bar 32 secured in the decorative body 31, and an extension shank 33 having a first end connected with the fixing bar 32 and a second end connected with an upper end of the support bar 27 of the driving device 2 so that the decorative body 31 is movable in concert with the support bar 27 of the driving device 2. The decorative body 31 of the decorative unit 3 encompasses the support bar 27 of the driving device 2. The decorative body 31 of the decorative unit 3 is a detachable element and has a determined shape, pattern, figure or the like. Preferably, the decorative body 31 of the decorative unit 3 is made of a cloth which is decorated to have the profile of a ghost or the like to provide a frightening effect. The extension shank 33 of the decorative unit 3 is received in the decorative body 31.

In assembly, the drive motor 22 is initially mounted in the mounting seat 21. Then, the mounting seat 21 is mounted on the housing 11. Then, the drive wheel 23 is mounted in the mounting seat 21. Then, the torsion springs 28 are mounted on the two opposite sides of the driven wheel 25. Then, the driven wheel 25 is mounted on the mounting seat 21, with the driven teeth 26 of the driven wheel 25 meshing with the drive teeth 24 of the drive wheel 23. Then, the first end of each of the torsion springs 28 is connected with the mounting seat 21, and the second end of each of the torsion springs 28 is connected with the support bar 27. Finally, the extension shank 33 is connected with the support bar 27 to connect the decorative unit 3 with the driving device 2, thereby accomplishing assembly of the prank apparatus.

As shown in FIG. 4, the base unit 1 further includes a plurality of connecting brackets 17 mounted on a periphery of the housing 11, and a plurality of stands 18 connected with the connecting brackets 17 respectively to enhance rigidity and stability of the housing 11.

In operation, referring to FIGS. 5-7 with reference to FIGS. 1-3, the control switch 14 of the base unit 1 is switched to turn on the driving device 2 so that the drive motor 22 can be operated to drive the drive wheel 23. At this time, the user can transmit a signal to the sensor 13. For example, the user can transmit a sound signal to the sensor 13 by clapping, shouting or the like. In such a manner, after the sensor 13 receives the signal from the user, the sensor 13 transmits a signal to the control board 16 which starts the drive motor 22 which drives the drive wheel 23 to rotate in the counterclockwise direction as shown in FIG. 5. At this time, the driven teeth 26 of the driven wheel 25 mesh with the drive teeth 24 of the drive wheel 23 so that the driven wheel 25 is driven by the drive wheel 23 to rotate in the clockwise direction so as to move the support bar 27 and the extension shank 33 downward and backward and to compress the torsion springs 28 for storing a restoring force. Subsequently, the drive wheel 23 is further rotated in the counterclockwise direction until the driven teeth 26 of the driven wheel 25 disengage the drive teeth 24 of the drive wheel 23 as shown in FIG. 6 so that the driven wheel 25 is released from the drive wheel 23 and is pushed by the restoring force of the torsion springs 28 to rotate in the counterclockwise direction so as to move the support bar 27 and the extension shank 33 upward. In such a manner, the support bar 27 and the extension shank 33 are moved upward and forward by the restoring force of the torsion springs 28 so that the decorative body 31 of the decorative unit 3 is instantaneously sprung upward and forward. At the same time, the sounder 12 can emit a sound when the decorative body 31 of the decorative unit 3 is sprung upward and forward. Thus, after the sensor 13 receives the signal from the user, the decorative body 31 of the decorative unit 3 is sprung upward and forward, and the sounder 12 emits a corresponding sound so as to achieve a video/audio frightening amusement effect. In practice, the prank apparatus is placed in a site, such a haunted house and the like, and is available for a festival, such as the Halloween day and the like. Subsequently, the drive wheel 23 is further rotated in the counterclockwise direction until the driven teeth 26 of the driven wheel 25 mesh with the drive teeth 24 of the drive wheel 23 again as shown in FIG. 7 so that the driven wheel 25 is driven by the drive wheel 23 to rotate in the clockwise direction again so as to move the support bar 27 and the extension shank 33 downward and backward and to compress the torsion springs 28 for storing a restoring force.

Referring to FIG. 8, a prank apparatus in accordance with another preferred embodiment of the present invention is shown. The base unit 1 further includes a support rack 19 mounted on the housing 11. The decorative unit 3 includes an extension shank 33 having a first end connected with the support bar 27 of the driving device 2 and a second end provided with an elongate guide slot 34, a movable pin 36 movably mounted in the guide slot 34 of the extension shank 33, a first link 35 having a first end pivotally connected with the movable pin 36, a decorative body 31 mounted on a second end of the first link 35, and a second link 37 having a first end pivotally connected with the support rack 19 of the base unit 1 and a second end pivotally connected with the first link 35. The second end of the second link 37 is located between the movable pin 36 and the decorative body 31. The decorative body 31 is movable in concert with the support bar 27 of the driving device 2.

In operation, referring to FIGS. 9-11 with reference to FIG. 8, the control switch 14 of the base unit 1 is switched to turn on the driving device 2 so that the drive motor 22 can be operated to drive the drive wheel 23. At this time, the user can transmit a signal to the sensor 13. For example, the user can transmit a light-sensitive signal, such as an infrared ray and the like, to the sensor 13. In such a manner, after the sensor 13 receives the signal from the user, the sensor 13 transmits a signal to the control board 16 which starts the drive motor 22 which drives the drive wheel 23 to rotate in the counterclockwise direction as shown in FIG. 9. At this time, the driven teeth 26 of the driven wheel 25 mesh with the drive teeth 24 of the drive wheel 23 so that the driven wheel 25 is driven by the drive wheel 23 to rotate in the clockwise direction so as to move the support bar 27 and the extension shank 33 downward and backward and to compress the torsion springs 28 for storing a restoring force. Subsequently, the drive wheel 23 is further rotated in the counterclockwise direction until the driven teeth 26 of the driven wheel 25 disengage the drive teeth 24 of the drive wheel 23 as shown in FIG. 10 so that the driven wheel 25 is released from the drive wheel 23 and is pushed by the restoring force of the torsion springs 28 to rotate in the counterclockwise direction so as to move the support bar 27 and the extension shank 33 upward. In such a manner, when the support bar 27 and the extension shank 33 are moved upward and forward by the restoring force of the torsion springs 28, the first link 35 is moved upward and forward by a sliding motion of the movable pin 36 in the guide slot 34 of the extension shank 33, and the second link 37 is moved upward and forward by push of the first link 35 so that the decorative body 31 of the decorative unit 3 is instantaneously sprung upward and forward. At the same time, the sounder 12 can emit a sound when the decorative body 31 of the decorative unit 3 is sprung upward and forward. Thus, after the sensor 13 receives the signal from the user, the decorative body 31 of the decorative unit 3 is sprung upward and forward, and the sounder 12 emits a corresponding sound so as to achieve a video/audio frightening amusement effect. Subsequently, the drive wheel 23 is further rotated in the counterclockwise direction until the driven teeth 26 of the driven wheel 25 mesh with the drive teeth 24 of the drive wheel 23 again as shown in FIG. 11 so that the driven wheel 25 is driven by the drive wheel 23 to rotate in the clockwise direction again so as to move the support bar 27 and the extension shank 33 downward and backward and to compress the torsion springs 28 for storing a restoring force.

In a further preferred embodiment of the present invention, the sensor 13 of the base unit 1 is a contact switch (such as a footpad control switch, a try-me switch or the like). In practice, the sensor 13 of the base unit 1 has a connecting line which has a terminal embedded in a determined position of the housing 11. Thus, when the user touches the terminal of the connecting line of the sensor 13, the sensor 13 of the base unit 1 is operated to actuate the driving device 2.

Accordingly, after the sensor 13 receives the signal from the user, the decorative body 31 of the decorative unit 3 is initially moved downward and backward slowly and then sprung upward and forward suddenly, and the sounder 12 emits a corresponding sound simultaneously. In addition, the sensor 13 of the base unit 1 is operated in an optical, acoustical and manual contact manner so that the user can control the sensor 13 to actuate the driving device 2 so as to move the decorative body 31 of the decorative unit 3 easily and quickly.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention.
