1. Field of the Invention
The present invention relates to an inflatable figure and more particularly to a rocking inflatable figure.
2. Description of the Related Art
Inflatable figures are normally used for occasions of all kinds of exhibitions, carnivals and parties for the advertising, decorating and entertaining purposes.
Conventional inflatable figures are structurally simple and each of which has a hollow inflatable body and an air pump. The inflatable body has an air inlet formed through a bottom of the inflatable body. The air pump is mounted to align with the air inlet of the inflatable body so as to pump air into the inflatable body and expand the inflatable body. After being inflated, the inflatable body deployed at the sites of the foregoing occasions can deliver entertaining and amusing effect to the surrounding people.
However, conventional inflatable figures can be only statically exhibited and easily become stereotypical in terms of visual reception. Therefore, toy industry is constantly conceiving how to improve the design of inflatable figures by providing satisfactory entertaining and animated effect through added motion of the inflatable figures.
An objective of the present invention is to provide a rocking inflatable figure capable of presenting a continuously rocking form to increase the animated viewing fun.
To achieve the foregoing objective, the rocking inflatable figure has an inflatable body, a rocking mechanism and an air pump.
The inflatable body is hollow and has an air inlet, a movable portion and two partition diaphragms.
The air inlet is formed through the inflatable body.
Each partition diaphragm is securely mounted on an inner wall of the movable portion.
The rocking mechanism is mounted inside the movable portion of the inflatable body and between the two partition diaphragms, and has a housing, an oscillating lever, an electric motor and a transmission mechanism.
The housing is securely mounted inside the movable portion and on one of the partition diaphragms.
The oscillating lever has a distal end and a proximal end relative to the housing.
The distal end is securely connected to the other partition diaphragm.
The proximal end is pivotally mounted on the housing.
The electric motor is mounted inside the housing.
The transmission mechanism is mounted inside the housing and is connected with the electric motor and the oscillating lever for the electric motor to drive the transmission mechanism and for the transmission mechanism to drive the oscillating lever to continuously oscillate with respect to the pivot center of the oscillating lever.
The air pump is mounted inside the inflatable body and is aligned with the air inlet of the inflatable body.
The air pump of the rocking inflatable figure first pumps air into the inflatable body. After the electric motor starts, the electric motor drives the oscillating lever on the housing to oscillate. As the housing and the oscillating lever are securely mounted on the two partition diaphragms in the movable portion, the partition diaphragm securely mounted on the oscillating lever thereon continuously rocks relative to the partition diaphragm securely mounted on the housing when the oscillating lever keeps oscillating relative to the housing. Accordingly, the movable portion also presents a continuously rocking posture. Vendors of the rocking inflatable figures can tailor user's demand to design the movable portion as the waist, neck or the like of the figure to focus on the rocking effect of the upper portion or the head of the figure and increase the viewing fun of the inflatable figures.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The inflatable body 10 is hollow and has an air inlet 11, a movable portion 12 and two partition diaphragms 13. In the present embodiment, the inflatable body 10 has an upper portion 101 and a lower portion 102. The movable portion 12 is formed between the upper portion 101 and the lower portion 102 and serves as a waist of the inflatable body 10. Each partition diaphragm 13 is securely mounted on an inner wall of the movable portion 12 and has multiple air vents 131 formed through the partition diaphragm 13. The air inlet 11 is formed through a bottom of the inflatable body 10.
The rocking mechanism 20 is mounted inside the movable portion 12 of the inflatable body 10 and between the two partition diaphragms 13, and has a housing 21, an oscillating lever 22, an electric motor 23 and a transmission mechanism 24. The housing 21 is securely mounted inside the movable portion 12 and on one of the partition diaphragms 13. With reference to
The air pump 30 is mounted inside the inflatable body 10 and is aligned with the air inlet 11 of the inflatable body 10. In the present embodiment, the air pump 30 is mounted on a seat 31.
The string light 40 is mounted inside the inflatable body 10.
The rocking mechanism 20 further has two fixing bases 25, 26 and two flexible plates 27, 28. Each fixing base 25, 26 is securely mounted on one of the housing 21 and the oscillating lever 22 and abuts against a surface of a corresponding partition diaphragm 13 facing the fixing base 25, 26. Each flexible plate 27, 28 is mounted on a surface of a corresponding partition diaphragm 13 opposite to a corresponding fixing base 25, 26. Hence, each partition diaphragm 13 is held by a corresponding flexible plate 27, 28 and a corresponding fixing base 25, 26 so that the housing 21 and the oscillating lever 22 are fastened on the partition diaphragms 13.
With reference to
The oscillating lever 22 has a side wing 221. The electric motor 23 has a spindle 231. The transmission mechanism 24 has a reduction gear assembly 241, an eccentric wheel 242 and a push rod 243.
The reduction gear assembly 241 is rotatably mounted inside the housing 21, is connected with the spindle 231 of the electric motor 23, and is driven by the electric motor 23. The eccentric wheel 242 is connected with the reduction gear assembly 241, is rotated by the reduction gear assembly 241, and has an eccentric shaft 242a.
One end of the push rod 243 is pivotally mounted on the eccentric shaft 242a, and the other end of the push rod 243 is pivotally mounted on the side wing 221 of the oscillating lever 22. When the eccentric wheel 242 is rotated, the push rod 243 drives the side wing 221 and the oscillating lever 22 to oscillate with respect to the pivot center of the oscillating lever 22.
The housing 21 has a gearbox and a motor cover 212. The gearbox has two half cases 211a, 211b jointed together. The reduction gear assembly 241 is rotatably mounted inside the two half cases 211a, 211b. One of the half cases 211b has a motor holder 211c formed on a periphery of the half case 211b. The electric motor 23 is mounted in the motor holder 211c. The motor holder 211c has a spindle hole 211d for the spindle 231 of the electric motor 23 to connect with the reduction gear assembly 241 in the gearbox through the spindle hole 211d.
The motor cover 212 corresponds to and is mounted on the motor holder 211c to cover the electric motor 23 within the motor holder 211c and the motor cover 212. In the present embodiment, the motor cover 212 has a power wire box 213. The power wire box 213 is formed on the periphery of the motor cover 212 with one side open and has two wire holes 214 and a lid 215. The wire holes 214 are formed through the power wire box 213 and the motor cover 212 for power wires to connect with the electric motor 23 through the respective wire holes 214. The lid 215 is mounted on the power wire box 213 to cover the power wire box 213.
To prevent the electric motor 23 from being damaged by rain penetration into the motor holder 211c when the rocking inflatable figure is mounted outdoors, a first waterproof seal ring 216 and a second waterproof seal ring 217 are respectively mounted between the motor holder 211c and the motor cover 212 and inside the spindle hole 211d of the housing 21. The motor cover 212 abuts against the first waterproof seal ring 216 on the perimeter of the inner bottom of the motor holder 211c. The spindle 231 of the electric motor 23 is sleeved in the second waterproof seal ring 217 abutting against an inner wall of the spindle hole 211d of the housing 21. A waterproof adhesive layer 218 is mounted inside the power wire box 213 to cover the wire holes 214.
With reference to
In sum, besides exhibiting a continuously rocking form to increase an entertaining and decorative effect, the rocking inflatable figure can be also used for nighttime activities to satisfy different users' demands.
