(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 is 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 As the gear rack is withdrawn from the toy, a wheel ejector coupled to the gear rack pivots to force the wheel off of the shaft and launch the wheel.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 increasing 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.
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. 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. An energy storing system is mounted inside the housing and drivingly connected with the launcher rotating system. The energy storing system is configured to store kinetic energy where upon release, the kinetic energy is converted to actuate the launcher rotating system, whereby a user may use the toy to rotate and launch an object from the toy.
In another aspect, the launcher rotating system includes a launcher attachment mechanism that is formed to enable the object to be detachably attached with the toy. The launcher attachment mechanism is formed to engage with a corresponding object attachment mechanism such that upon actuation of the launcher attachment mechanism, the object attachment mechanism is released from the toy.
In yet another aspect, the present invention further comprises a key for winding energy storing system to store kinetic energy therein. A trigger is also included for actuating the energy storing system and the launcher attachment mechanism. Upon actuation, the energy storing in the energy storing system is released to cause the launcher rotating system to rotate the launcher and the launcher attachment mechanism releases the object attachment mechanism, thereby launching the object.
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. The receiving element of the object is similarly configured with two substantially helical tabs extending outward in parallel configuration about an axis. The axis runs perpendicular to the rotational motion of the object. 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.
Additionally, the launcher rotating system comprises a series of interconnected gears and axles, which are capable of rotating the launcher. In another aspect, the radius of the gears is selected to provide a desired input-to-output gear ratio.
Finally, the present invention also comprises a method for forming and using the toy described herein. In one aspect, the method comprises acts of a housing; forming a launcher extending from the housing, the launcher configured to impart a rotary motion to an object, wherein the launcher comprises a driving element configured to engage a receiving element, the receiving element 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; mounting a launcher rotating system inside the housing and connecting the launcher rotating system with the launcher, the launcher rotating system configured to impart a rotary motion to the launcher; and mounting an energy storing system inside the housing and drivingly connecting the energy storing system with the launcher rotating system, the energy storing system configured to store energy where upon release, the potential energy is converted to actuate the launcher rotating system, whereby a user may use the toy to rotate and launch an object from the toy.
In another aspect, the method comprises the act of forming a launcher attachment mechanism to enable the object to be detachably attached with the toy, wherein the launcher attachment mechanism is formed to engage with a corresponding object attachment mechanism such that upon actuation of the launcher attachment mechanism, the object attachment mechanism is released from the toy.

Before describing the invention in detail, an introduction is provided to provide the reader with a general understanding of the present invention. Next, a description of various aspects of the present invention is provided to give an understanding of the specific details.
The present invention relates to a toy for rotating and launching an object. More specifically, the present invention relates to a ripcord-less launcher for launching the object.
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 user may turn a key to wind up a gear train in the toy. Alternatively, the user may rotate the object (after the object is attached with the launcher) backwards to wind up the gear train. Upon activating the release button, the shaft is rotated which, in turn, rotates the object mounted to the launcher. A release mechanism is actuated by the release button to release the rotating object, thereby launching the object away from the launcher. The launcher is configured to release the object in only one direction.
In one aspect, as illustrated in
Using the trigger 116, the energy can be released from the system and the object launched from the launcher 106. When the energy is released from the energy storing system 112, the launcher rotating system 108 translates the potential energy into movement of the gear train 114 in a rotary motion. The launcher rotating system 108 is then drivingly connected with the launcher 106. When an object such as a wheel is connected with the launcher 106, the launcher 106 rotationally accelerates the wheel until the wheel is released from the launcher 106 and propelled forward.
The launcher 106 functions to retain an object, rotate the object, and launch the object. In one aspect, the launcher 106 is mounted to an output axle 118 which is drivingly connected with the gear train 114.
Referring again to
Once an interlocking drive connection is made between the driving element 121 and the receiving element 123, the user can turn the key 110 to build the amount of potential energy stored in the energy storing system 112. When the user pulls the trigger 116, the launching rotating system 108 translates the potential energy into a rotary motion to rotate the driving element 121 and thereby rotate the object connected with the receiving element 123. When the launcher rotating system 108 ceases to accelerate the launcher 106 and the driving element 121, the receiving element 123 disengages from the driving element 121 and releases the object from the interlocking drive connection. This is accomplished because once the launcher rotating system 108 ceases to rotate the driving element 121, the rate of rotation of the driving element 121 decreases immediately. However, due to the object's inertia, the rotational velocity of the receiving element 123 decreases more slowly, and the object and receiving element 123 rotate away from the driving element 121 and disengage from the interlocking drive connection. Thus, once the object is affixed with the launcher 106 (and the energy storing system 112 is wound up), a user may use the trigger 116 to release the object from the interlocking drive connection, which forces the object attachment mechanism 125 to be released from the launcher attachment mechanism 124, thereby launching the object.
It should be noted that the object is any suitable object that can be launched from the toy, non-limiting examples of which include balls and wheels. In the aspect where the object is a wheel 202, the receiving element 123 is rotationally connected with the hub 204 of the wheel 202, as illustrated in
Referring again to
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 train 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.
