Description

BACKGROUND OF THE INVENTION

(1) Technical Field

The present invention relates to a toy for rotating and launching an object, and more particularly to a launching mechanism that attaches with a users arm for rotating and launching an object.

(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 As the gear rack is withdrawn from the toy, a wheel ejector coupled to the gear rack pivots to force the wheel off of the shaft and launch the wheel.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.

Additionally, in some circumstances, it may be desirable to attach the launcher with a user. However, existing devices do not provide for such an attachment

Therefore, a need exists for a toy launcher that can be attached with a user and that is capable of preventing the toy from being launched in the direction of the user.

Next, a description of various aspects of the present invention is provided to give an understanding of the specific details.

(1) Introduction

The present invention relates to a toy for rotating and launching an object. More specifically, the present invention relates to a launching mechanism that attaches with a users arm for rotating and launching an object. The launcher is formed to hold, rotate and release an object. The object is any roll-able object, non-limiting examples of which include a toy wheel and a ball. As can be appreciated by one skilled in the art, the object can be used with other launching devices.

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.

(2.1.1) Basic Operation

In one aspect, as illustrated in FIG. 1, the toy 100 comprises a housing 102, an arm attachment mechanism 104, a launcher 106, and a launcher rotating system (not illustrated) including a gear rack 108. The launcher rotating system is located inside the housing 102, and the launcher rotating system is drivingly connected with the gear rack 108 such that when the gear rack 108 is moved, the launcher rotating system translates the movement of the gear rack 108 into a rotary motion. The launcher rotating system is then drivingly connected with the launcher 106. When an object such as a wheel 110 is connected with the launcher 106, as in FIG. 2, the launcher 106 rotationally accelerates the wheel 110 until the wheel 110 is released from the launcher 106 and propelled forward. As can be appreciated by one skilled in the art, the object is any rollable object, non-limiting examples of which include a toy wheel and a ball.

Although a gear rack 108 is shown in the aspect of FIG. 1, one skilled in the art will appreciate that the launcher rotating system can comprise a motor or other manually operated mechanism to cause the rotation of the launcher 106.

(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 FIG. 3, the launcher 106 is mounted to an output axle 300 which is drivingly connected with the launcher rotating system 302. FIG. 3 illustrates the specific design of one aspect of the launcher 106, including a driving element 304. The driving element 304 comprises two identical helical tabs 306, which extend outward in parallel configuration from the output axle 300 about an axis, such that the axis is running parallel to and centered in the output axle 300. The edges of each of the helical tabs 306 are formed into hook shapes.

FIG. 4 illustrates how the helical tabs 306 of the driving element 304 are configured to interlock, as matching and interlocking shapes, with similar helical tabs 400 on a receiving element 402, the receiving element 402 connected with an object to be rotated (not illustrated). In particular, the hook-shaped edges 404 of the driving element 304 are configured to match up with the hook-shaped edges 406 of the receiving element 402, forming an interlocking drive connection. The interlocking drive connection allows a user to rotate the toy in any orientation and still maintain the interlocking drive connection between the driving element 304 and the receiving element 402.

Once the interlocking drive connection is made between the driving element 304 and the receiving element 402, the user can pull the gear rack (not illustrated) to rotate the driving element 304 and thereby rotate the object connected with the receiving element 402. 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 106 and the driving element 304. Once the driving element 304 ceases to accelerate the receiving element 402, the receiving element 402 disengages from the driving element 304 and releases the object from the interlocking drive connection. This is accomplished because once the launcher rotating system ceases to rotate the driving element 402, the rate of rotation of the driving element 304 decreases immediately. However, due to the object's inertia, the rotational velocity of the receiving element 402 decreases more slowly, and the object and receiving element rotate away from the driving element 304 and disengage from the interlocking drive connection.

Due to the design of the launcher 106 and specifically the helical tabs 306 of the driving element 304, the rotation of the launcher 106 will impart a rotation to the receiving element 402 only if rotated in a clockwise direction. If the launcher 106 is rotated in a counter-clockwise direction, the hook-shaped edges 404 of the driving element 304 will rotate away from the hook-shaped edges 406 of the receiving element 402 and disengage the interlocking drive connection without imparting any rotational motion to the receiving element 402.

In the aspect where the object is a wheel 110, the receiving element 402 is connected with the hub 500 of the wheel, as illustrated in FIG. 5.

(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 FIG. 6, the launcher rotating system 302 comprises an input axle 600 with an input pinion 602 and an input gear 604, where the input pinion 602 is drivingly connected with a gear rack 108. The launcher rotating system 302 further comprises an output axle 300 with an output gear 606, where the output gear 606 is drivingly connected with the input gear 604, and where the output axle 300 is connected with the launcher 106.

Because the toy 100 is formed to be attached with a user's arm, it is desirable to have the input pinion 602 accessible at a top portion of the housing 102 while the wheel is launched from the side of the housing 102. In this aspect, the input axle 600 is positioned approximately perpendicular to the output axle 300.

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 608 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) Arm Attachment Mechanism

As shown in FIG. 7, the toy 100 is formed to be attached with a user's arm. To enable attachment, an arm attachment mechanism 104 is included. The arm attachment mechanism 104 includes an arm strap 700 and a handle 702. The arm strap 700 is any suitable device for strapping the toy 100 to a user's arm, non-limiting examples of which include an elastic band, two bands with an attachment device (e.g., Velcro) to attach the two bands, and a band with an attachment device (e.g., clip) to attach with the housing 102.

As shown in FIG. 8, using the arm strap, a user 800 can attach the toy 100 with a user's arm, thereby allowing a user to hold the handle 702 with one hand while using the other hand to draw the gear rack to launch the object 110.
