2. Description of Related Arts
A plurality of air-floating toys are known which are capable of self-floating in the air and propelling in the air via a remote control. In particular, the air-floating toys are driven by means of a wiggling motion. However, the conventional air-floating toy is hard to be controlled its direction and elevation. An improved air-floating toy generally comprises a toy body, a driving mechanism and a steering mechanism to control the altitude and the direction of the air-floating toy respectively via a remote controller.
The driving mechanism is affixed underneath the toy body to control the altitude thereof, wherein the driving mechanism comprises an elongated track member longitudinally affixed to the bottom side of the toy body and a weight member sildably coupled along the track member. When the weight member is controlled via the remote controller to slide toward the head of the toy body, the weight of the weight member is shifted frontwardly, so as to shift the center of mass of the toy body frontwardly. Therefore, the toy body is dropped downwardly to lower the altitude of the air-floating toy. Likewise, when the weight member is controlled via the remote controller to slide toward the tail of the toy body, the weight of the weight member is shifted rearwardly, so as to shift the center of mass of the toy body rearwardly. Therefore, the toy body is elevated upwardly to increase the altitude of the air-floating toy. However, the driving mechanism has several drawbacks.
The track member must be securely affixed to bottom side of the toy body. Preferably, a front end, a rear end, and a mid-portion of the track member are glued to the toy body to form a three-point support, such that the weight member can be controllably slid between the front and rear ends of the track member to select the shifting position of the weight member. However, the track member cannot be secured to the bottom side of the toy body. In other words, the track member can be easily detached from the toy body when the toy body is drastically dropped on the floor or by any strong impact. In addition, the weight of weight member keeps shifting between the front and rear ends of the track member, such that the sliding movement and the weight shifting force will cause the track member detaching from the toy body. Accordingly, if one point of the track member is disengaged with the toy body, the weight member will be misaligned to slide at the bottom side of the toy body. In worst case, if one of the front and rear ends of the track member is detached from the bottom side of the toy body, the weight member will not able to slide at the track member to control the altitude of the air-floating toy.
Furthermore, the weight member comprises a gear wheel powered by a battery to rotatably engage with a gear track along the track member. The gear wheel is actuated to rotate via a motor electrically connected to the battery. However, the actuation of the gear wheel requires relatively higher electrical power such that the weight member will run out of battery rapidly. An unavoidable noise will be generated during the actuation of the gear wheel.
The driving mechanism requires relatively larger installation space at the bottom side of the toy body. As it is mentioned above, the track member is longitudinally affixed to the bottom side of the toy body at a position that the front and rear ends of the track member are extended toward the head and tail of the toy body respectively. The length of the track member must be long enough in order for the weight member to slide therealong so as to shift the weight back and forth. In other words, the size of the driving mechanism cannot be minimized and the driving mechanism will destroy the aesthetic appearance of the toy body especially when the toy body floats in the air.
The invention is advantageous in that it provides an air swimming toy, wherein a driving device of the air swimming toy is arranged for creating an air dynamic underneath the toy body to control the altitude of the air swimming toy.
Another advantage of the invention is to provide an air swimming toy, wherein an air pressure difference is created underneath the toy body by the driving device to control the altitude of the air swimming toy.
Another advantage of the invention is to provide an air swimming toy, wherein the air pressure difference is created by an air propelling force to control the altitude of the air swimming toy.
Another advantage of the invention is to provide an air swimming toy, wherein the driving device comprises an air propeller to create the air propelling force underneath the air swimming toy so as to control the altitude of the air swimming toy.
Another advantage of the invention is to provide an air swimming toy, wherein the driving device is fixed at the bottom side of the toy body without any moving or sliding part along the toy body so as to prevent the driving device being detached from the toy body accidentally.
Another advantage of the invention is to provide an air swimming toy, wherein the size of the driving device is relatively small to minimize the installation space at the toy body so as to keep the aesthetic appearance of the air swimming toy.
Another advantage of the invention is to provide an air swimming toy, wherein only the air propeller is driven to create the air propelling force to minimize the noise from the driving device during operation.
Another advantage of the invention is to provide an air swimming toy, which does not require to alter the original structural design of the toy body, so as to minimize the manufacturing cost of the air swimming toy incorporating with the driving device.
Another advantage of the invention is to provide an air swimming toy, wherein no expensive or complicated structure is required to employ in the present invention in order to achieve the above mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution for providing a stable and silent operation for the driving device to control the altitude of the air swimming toy.

The toy body 10 comprises a floating body 11 and a tail body 12 movably coupled with the floating body 11, wherein the floating body 11 is filled with a particular gas, such as helium, in order to float in the air. In particular, the toy body 10 further comprises a valve 13 provided at the floating body 11 for filling the gas thereinto. The floating body 11 is made of high quality, durable nylon material that will stay inflated for a relatively long period of time, such as a week. The gas can be refilled to the floating body 11 via the valve 13 to inflate the floating body 11.
Accordingly, when the tail body 12 is moved in a wiggling motion, the toy body 10 will move forward slowly and smoothly as the swimming motion in the air. The tail body 12 is also formed as a steering member of the toy body 10 that when the tail body 12 is moved sidewardly, the toy body 10 will turn correspondingly.
The air swimming toy further comprises a steering device 40 provided at a connection between the floating body 11 and the tail body 12 to drive the tail body 12 to move in a wiggling motion. In other words, the steering device 40 not only forms a movable joint to connect the tail body 12 to the floating body 11 but also forms a propelling unit to drive and steering the toy body 10 forward.
The driving device 20 of the present invention is used for controlling an altitude of the toy body 10 but not the forward driving movement thereof. In other words, the driving device 20 of the present invention is arranged for controllably elevating the toy body 10 and for controllably dropping down the toy body 10.
As shown in
The air propeller 21 is supported at a bottom side of the floating body 11 of the toy body 10 for creating an air dynamic underneath the toy body 10. The air dynamic at the bottom side of the toy body 10 will either create an upward elevating force to elevate the toy body 10 or create a downward dropping force to drop down the toy body 10. Accordingly, the air propeller 21 is activated to rotate in order to control an altitude of the toy body 10 via the air dynamic, i.e. the up and down movement of the toy body 10. The air propeller 21 comprises a plurality of airfoil-shaped blades for transmitting rotational motion into thrust. It is worth mentioning that the air propeller 21 is not arranged for propelling the toy body 10 forward but for controlling the altitude of the toy body 10. The air propelling terminology is old and well known for propelling an object forward. For example, an airship is propelled through the air using propellers or other thrust mechanisms to move the airship forward. A helicopter is propelled by rotary wing terminology to elevate the helicopter. However, none of the existing object incorporates with the air propeller 21 at the bottom side as the air swimming toy of the present invention in order to control the altitude of the air swimming toy.
The operative housing 22 is mounted at the bottom side of the floating body 11 of the toy body 10, wherein the air propeller 21 is housed in the operative housing 22 to create the air dynamic within the operative housing 22. In particular, the operative housing 22 is shaped in an aerodynamic configuration, wherein the operative housing 22 has an enlarged head portion 221 to receive the air propeller 21 therein, and an elongated tail portion 222 extended toward a tail portion of the toy body 10, i.e. the tail body of the toy body 10. The operative housing 22 further has a curved front surface 223 at the front side of the head portion 221 and a streamlined bottom surface 224 extended from the head portion 221 to the tail portion 222 for reducing an air drag of the operative housing 22.
The operative housing 22 further has a plurality of side air vents 225 formed at two sidewalls of the head portion 221 and a plurality of bottom air vents 226 formed at the bottom surface 224 at the head portion 221.
The motorized unit 23 is operatively connected to the air propeller 21 to drive the air propeller 21 to rotate for creating a controllable air pressure underneath the toy body 10 at the floating body 11 thereof, wherein the motorized unit 23 comprises a driving shaft 231 sidewardly extended with respect to the toy body 10 to couple with the air propeller 21. In particular, the air propeller 21 is coupled at the driving shaft 231 to be rotated at a direction with respect to a centerline of the toy body 10. Preferably, the rotational direction of the air propeller 21 is supported and aligned with the centerline of the toy body 10.
Accordingly, when the controllable air pressure is lesser than a surrounding air pressure, the toy body 10 is elevated in the air, and when the controllable air pressure is higher than the surrounding air pressure, the toy body 10 is dropped down in the air. It is worth mentioning that through the side air vents 225 and the bottom air vents 226, the air propeller 21 can create a difference between the controllable air pressure and the surrounding air pressure. As shown in
According to the preferred embodiment, the motorized unit 23 is a DC motor and is controlled to generate a reversible rotating power to selectively drive the air propeller 21 between two opposite rotating directions. In other words, when the air propeller 21 is driven to rotate at a forward direction, the controllable air pressure will be reduced in the operative housing 22. When the air propeller 21 is driven to rotate at a backward or reversed direction, the controllable air pressure will be increased in the operative housing 22.

According to the preferred embodiment, the remote controller 30 is remotely controlling the driving device 20 to operate the air propeller 21. In particular, the remote controller 30 is wirelessly control the driving device 20 and the steering device 40. Therefore, the remote controller 30 is arranged to control the altitude of the toy body 10 via the driving device 20, and is arranged to control the steering and propelling of the toy body 10 via the steering device 40.
As shown in
The present invention further provides a method of controlling an altitude of the air swimming toy, comprising the following steps.
(1) Support the air propeller 21 at the bottom side of the toy body 10 for creating the air dynamic underneath the toy body 10. Accordingly, the toy body 10 is filled with the gas in order to float in the air.
According to the preferred embodiment, the mounting platform 25 is affixed to the bottom side of the floating body 11 of the toy body 10 such that the motorized unit 23 is coupled underneath the toy body 10 to support the air propeller 21 at the bottom side of the toy body 10.
The battery is placed at the battery compartment 24 to electrically connect to the motorized unit 23. Then, the operative housing 22 is coupled with the mounting platform 25 to enclose the motorized unit 23 and the air propeller 21 within the operative housing 22.
(2) Activate the air propeller 21 to rotate in order to control the altitude of the toy body 10 via the air dynamic.
Once the power of the motorized unit 23 is switched on, the air propeller 21 is activated to rotate when the remote receiver 32 receives the control signal from the handheld control 31. The air propeller 21 will start to rotate to create the air dynamic within the operative housing 22 for creating the controllable air pressure. Through the difference between the controllable air pressure and the surrounding air pressure, the toy body 10 will be selectively elevated at a predetermined height. It is worth mentioning that the toy body 10 will be elevated or dropped down gradually and slowly through the air dynamic.
