(2) Description of Related Art
Toy launchers are well known in the art. Toys that accelerate and launch gliders, helicopters, cars, and parachutes are well documented. One method of launching a toy is through a rotary motion, often utilizing a gear system to turn a shaft that rotates the toy.
An example of one launcher disclosed in U.S. Pat. No. 3,701,216, issued to Smith, III et al. (hereinafter “the Smith patent”). The launcher taught in the Smith patent uses a gear rack to drive a gear train and rotate a wheel that is mounted on a shaft. As the gear rack is withdrawn from the toy, a wheel ejector coupled to the gear rack pivots to force the wheel off of the shaft and launch the wheel.
The devices according to the Smith patent have several shortcomings, the first of which is the need for a separate mechanical ejector to release the wheel from the toy. In addition to adding to the cost to manufacture the toy, the wheel ejector device adds to the complexity of design of the toy.
Another shortcoming of the devices made according to the Smith patent is the possibility of causing injury to the user if the wheel is launched in the direction of the user. If the toy is particularly oriented, the wheel will rotate and launch toward the user, risking injury.
Therefore, a need exists for a toy launcher with a cost-effective launching mechanism built into the design of the toy and capable of preventing the toy from being launched in the direction of the user.
The present invention overcomes the aforementioned limitations and fills the aforementioned needs by providing a toy for rotating and launching an object having a water spray mechanism attached thereto. The toy comprises a housing with a launcher extending from the housing. The launcher is configured to impart a rotary motion to an object. The launcher comprises a driving element configured to engage a receiving element. The receiving element is attached with an object to form a drive connection, such that when the driving element engages the receiving element, the object is rotationally accelerated in one direction, and wherein once the driving element ceases to accelerate the receiving element, the receiving element disengages from the driving element and releases the object from the drive connection. A launcher rotating system is mounted inside the housing and connected with the launcher. The launcher rotating system is configured to impart a rotary motion to the launcher. A water spray mechanism for spraying water proximate the object is affixed with the housing such that when the object is rotating, the object spins through the water to deflect the water. Additionally, the water spray mechanism can be formed to spray water proximate the object as it spins. In another aspect, the water spray mechanism is formed to spray the water proximate the object to give the appearance of the object spraying the water while the object remains dry.
In another aspect, the driving element comprises two substantially helical tabs extending in a parallel configuration from the shaft about an axis, the axis running substantially parallel to and substantially centered in the shaft, and wherein the receiving element of the object is similarly configured with two substantially helical tabs extending outward in parallel configuration about an axis, the axis running perpendicular to the rotational motion of the object, and wherein the two substantially helical tabs of each of the driving element and receiving element has an edge that runs parallel to the axis of the respective driving element and receiving element, such that the edge of the driving element rests flush against the edge of the receiving element, forming a drive connection which allows the rotation of the driving element to rotate the receiving element.
In another aspect, the edge of the driving element and the edge of the receiving element are formed as matching and interlocking shapes, such that when the edge of the driving element is matched with the edge of the receiving element, an interlocking drive connection is formed.
In yet another aspect, the edge of the driving element and the edge of the receiving element are formed as a hook shapes, such that when the edge of the driving element is matched up with the edge of the receiving element, an interlocking drive connection is formed.
In another aspect, the launcher rotating system comprises a series of interconnected gears and axles, the gears and axles capable of rotating the launcher.
In another aspect, the series of interconnected gears and axles comprises an output axle connected with the launcher, the output axle coupled with an output gear, the output gear drivingly connected with an input gear on an input axle, the input axle connected with an input pinion, the input pinion in drivingly connected with a gear rack, said gear rack movably mounted in a guideway in the housing, said gear rack capable of moving to rotate the input pinion and thereby rotate the launcher rotating system.
In yet another aspect, the radius of the gears is selected to provide a desired input-to-output gear ratio.
Additionally, the water spray mechanism includes a water tank, a pump for pressurizing the tank, and an outlet proximate the launcher.

(1) Introduction
The present invention relates to a toy for rotating and launching an object. More specifically, the toy includes a water spray mechanism for spraying water proximate the object such that when the object rotates, the water is sprayed to give an appearance that the wheel is spraying the water.
The launcher is formed to hold, rotate and release an object such as a toy wheel. A launcher with a pair of helical tabs extends from a shaft on the toy and interlocks with matching tabs on an object to mount the object on the shaft. In one aspect, a removable gear rack is pulled to rotate a gear train in the toy, which in turn rotates the shaft and the launcher, thereby rotating the object mounted to the launcher. When the launcher ceases to accelerate the object, the tabs of the object disengage from the launcher, launching the object forward. The launcher is configured to release the object in only one direction, and a stopper gear will prevent the toy from rotating the object in the direction of a user.
Additionally, the launcher further includes a water tank and water pump. The water pump allows a user to create air pressure within the tank which is used to dispense the water. The water can be sprayed proximate the wheel to simulate burning out in water when the wheel is rotated, with the water being deflected. In another aspect, the water is sprayed proximate the wheel so that it gives the appearance of the wheel spraying the water, while the wheel remains dry.
For purposes of clarity, the present invention will first be described in terms of the launching mechanism and operation. Next, the water spray mechanism will be discussed.
(2.1.1) Basic Operation
In one aspect, as illustrated in
Although a gear rack 108 is shown in the aspect of
(2.1.2) Launcher Mechanism
The launcher functions to retain an object, rotate the object, and launch the object, without the need for a manual or mechanical release mechanism. In one aspect, as illustrated in
Once the interlocking drive connection is made between the driving element 204 and the receiving element 212, the user can pull the gear rack (not illustrated) to rotate the driving element 204 and thereby rotate the object connected with the receiving element 212. When the user pulls the gear rack to the point that it is no longer in contact with the launcher rotating system, the launcher rotating system ceases to accelerate the launcher 200 and the driving element 204. Once the driving element 204 ceases to accelerate the receiving element 212, the receiving element 212 disengages from the driving element 204 and releases the object from the interlocking drive connection. This is accomplished because once the launcher rotating system ceases to rotate the driving element 204, the rate of rotation of the driving element 204 decreases immediately. However, due to the object's inertia, the rotational velocity of the receiving element 212 decreases more slowly, and the object and receiving element rotate away from the driving element 204 and disengage from the interlocking drive connection.
Due to the design of the launcher 200 and specifically the helical tabs 206A and 206B of the driving element 204, the rotation of the launcher 200 will impart a rotation to the receiving element 212 only if rotated in a clockwise direction. If the launcher 200 is rotated in a counter-clockwise direction, the hook-shaped edges 208A and 208B of the driving element will rotate away from the hook-shaped edges 214A and 214B of the receiving element 212 and disengage the interlocking drive connection without imparting any rotational motion to the receiving element 212.
In the aspect where the object is a wheel 110, the receiving element 212 is rotationally connected with the hub 218 of the wheel, as illustrated in
(2.1.3) Launcher Rotating System
The launcher rotating system comprises a series of interconnected gears and axles to impart a rotary motion to the launcher. In one aspect, as illustrated in
In one aspect, the gear rack 108 is movably mounted in a guideway in the housing 102. The gear rack 108 further comprises a handle for a user to easily grip and pull the gear rack 108.
One skilled in the art will appreciate that by changing the radius of the interconnected gears and input pinions of the launcher rotating system, a desired input-to-output gear ratio can be achieved. For example, the radius of the gears and pinions can be reduced to provide for a faster rotation output to the launcher, due to the fact that a given movement of the gear rack produces more revolutions of the gears and input pinions than are produced with a greater radius of the gears and input pinions.
Additionally, one skilled in the art will appreciate that the gear mechanism described herein is for illustrative purposes and the invention is not intended to be limited thereto, as other gear mechanisms can be envisioned for spinning the toy wheel.
(2.1.4) Stopper Mechanism
An additional aspect of the toy is a stopper for preventing the object from rotating and launching in an undesired direction, e.g., in the direction of a user. In one aspect, illustrated in
One skilled in the art will appreciate that the stopper may consist of any mechanism designed to prevent the rotation and launch of the object in the direction of the user. For example, if the launcher rotating system comprises a motor, the motor may possess a device to detect a particular orientation of the device and thereby prevent the motor from operating in that orientation. Additionally, the stopper is an optional item and is not required for operation of the present invention.
