(1) Field of Invention
The present invention relates to a remotely controlled vehicle and, more particularly, to a remotely controlled vehicle having only two drive wheels, each of which are detachably attachable and are independently controlled.
(2) Description of Related Art
Remotely controlled (RC) vehicles have long been known in the art. RC vehicles typically include four wheels, with the front two being devoted to steering, while the rear two are attached to a drive train for propulsion. In production, a problem associated with creating a RC vehicle with four wheels is the additional costs of a servo mechanism to control the steering, and the additional costs of four as opposed to two wheels.
Furthermore, when turning an RC vehicle that includes four wheels, the vehicle cannot turn on the spot. In other words, the turning radius for a four-wheeled RC vehicle requires that the RC vehicle travel either forward or backward in an arc. Because of this constraint, four-wheeled RC vehicles cannot spin in place or make extremely tight turns, and instead, must often make a several point turn.
Additionally, the wheels are typically permanently affixed with the body of the RC vehicle. In circumstances where the wheels are not permanently affixed, the wheels are held on by bolts or nuts, requiring the use of tools to remove the wheel. Should a prior art RC vehicle be used in a terrain where a different type of wheel would be advantageous, either the wheel cannot be changed, or changing the wheels requires considerable time and effort.
Thus, a continuing need exists for a RC vehicle that saves production costs by operating with only two drive wheels and without a steering servo, that can make extremely tight turns, and that includes quick-release interchangeable wheels to provide for ease of changing the vehicles wheels.
The present invention relates to a remotely controlled (RC) vehicle. The RC vehicle comprises a body member having a left portion, a right portion, a top portion, a bottom portion, a front portion, and a rear portion.
A detachably attachable right wheel is rotationally mounted proximate the right portion of the body member for rotationally supporting the body member on a supporting surface. The right wheel has dimensions and a peripheral portion such that the peripheral portion of the right wheel extends beyond the top, bottom, and front portions of the body member. Additionally, a first motor is drivably coupled with the right wheel.
A detachably attachable left wheel is rotationally mounted proximate the left portion of the body member for rotationally supporting the body member on the supporting surface. The left wheel has dimensions and a peripheral portion such that the peripheral portion of the left wheel extends beyond the top, bottom, and front portions of the body member. A second motor is drivably coupled with the left wheel.
A receiver is attached with the body member for receiving control signals from a remotely controlled transmitter. The receiver is independently connected with both the first and second motors such that a control signal from the remotely controlled transmitter provides for independent control of each of the first and second motors and their respective right and left wheels.
A stabilization apparatus is attached with the body member such that when the wheels are engaged, the stabilization apparatus is forced against the supporting surface, thereby preventing the body member from continuously spinning in place.
Through use of a remotely controlled transmitter, a user can independently control each of the right and left wheels, such that uni-engagement of the left or right wheels alone causes the remotely controlled vehicle to turn, and bi-engagement of both the right and left wheels in opposite directions also causes the remotely controlled vehicle to turn, while bi-engagement in the same direction causes the remotely controlled vehicle to propel itself forward, thereby allowing a user to maneuver the remotely controlled vehicle in forward, reverse, left, and right directions.
In another aspect, the wheels are detachably attachable with the body member through the use of a quick release apparatus, such that actuation of the quick release apparatus releases at least one wheel, thereby allowing for placement of another interchangeable wheel.
Furthermore, both the first and second motors are encased within the body member.
In another aspect, the body member is formed such that it is water resistant, thereby protecting the remotely controlled vehicle from aqueous elements.
In another aspect, the present invention further comprises a remotely controlled transmitter configured to transmit control signals to the receiver. The remotely controlled transmitter includes a first controller and a second controller, where the first controller is configured to control the first motor and its corresponding right wheel, and where the second controller is configured to control the second motor and its corresponding left wheel.
In another aspect, the stabilization apparatus includes a rod connected with the body member, the rod having an outer portion and at least two stabilization wheels rotationally attached with the outer portion, such that in operation, the remotely controlled vehicle rests upon the left wheel, right wheel, and stabilization wheels.
In another aspect, the rod is in a movable connection with the body member.
In yet another aspect, the present invention further comprises an antenna circumferentially disposed around the rod.
In yet another aspect, the antenna is formed to operate as a spring to force the stabilization wheel away from the body member, thereby minimizing impact forces against the body member when coming in contact with a surface.
Additionally, in the movable connection, the body member includes at least one sleeve, with the rod inserted within sleeve, thereby providing for a slide-able rod inserted within the body member and creating the movable connection.
In yet another aspect, the stabilization apparatus is attached proximate the rear edge of the body member.
Additionally, each detachably attachable wheel includes a central rotor.
In yet another aspect, the stabilization apparatus includes a roller ball encased within the stabilization apparatus such that outer portions of the roller ball extend beyond the stabilization apparatus.
In another aspect, the detachably attachable wheel is formed to be used with a device other than a remotely controlled vehicle.
In yet another aspect, the device other than a remotely controlled vehicle is a launcher for launching the detachably attachable wheel.
Finally, as can be appreciated by one skilled in the art, the present invention also comprises a method for forming the RC vehicle described herein.

(1) Introduction
The present invention relates to a remotely controlled vehicle and a launcher, both configured to operate with a detachably attachable wheel. The remotely controlled vehicle includes two, independently-controlled drive wheels, each of which are detachably attachable. The detachably attachable wheels can also be utilized with other devices such as a launcher. The launcher allows a user to attach the wheel with the launcher and thereby launch the detachably attachable wheel. For clarity purposes, the present invention will be described in two sections, the first describing various aspect of the remotely controlled vehicle with the second describing the launcher.
(2.1) Detailed Description of the Remote Controlled Vehicle
The present invention relates to a remotely controlled vehicle.
A detachably attachable right wheel 116 is rotationally mounted proximate the right portion 106 of the body member 102, while a detachably attachable left wheel 118 is rotationally mounted proximate the left portion 104 of the body member 102. Both the right wheel 116 and the left wheel 118 are attached for rotationally supporting the body member 102 when the RC vehicle 100 is placed upon a supporting surface. The body member 102 is formed such that the peripheral portions 120 of the right wheel 116 and left wheel 118 extend beyond the top 108, bottom 110, and front 112 portions of the body member 102.
A stabilization apparatus 208 is attached with the body member 102. The stabilization apparatus 208 assists in preventing the body member 102 from spinning around itself when one or both of the motors 200 and 202 are actuated. For example, when the motors 200 and 202 are actuated in a clockwise direction 210 to propel the RC vehicle 100 forward 212, a counter-clockwise force 214 is applied to the body member 102, thereby creating a tendency for the body member 102 to spin around itself. The stabilization apparatus 208 prevents this spinning by extending beyond the peripheral portions 120 of the wheels 116 and 118 and engaging with a supporting surface (e.g., ground surface). Because of the counter-clockwise force 214 of the body member 102, the stabilization apparatus 208 is forced in a downward direction 216 and against the supporting surface, thereby preventing the body member 102 from continuously spinning in place.
Additionally, by having the peripheral portions 120 of the wheels 116 and 118 extend beyond the top portion 108, bottom portion 110, and front portion 112 of the body member 102, the rear portion 114 of the body member 102 may be allowed to spin over the top portion 108 and thereby change the direction of the RC vehicle 100. For example, when the motors 200 and 202 are actuated in a counter-clockwise direction 214 to propel the RC vehicle 100 in reverse 218, an upward force 220 is applied to the stabilization apparatus 208, thereby flipping the stabilization apparatus 208 up and over to the opposite side of the RC vehicle 100 until it comes to rest against the supporting surface on the other side of the RC vehicle 100, also thereby causing the bottom portion 110 to now become the top portion 108. The operation described above enables a user to immediately change the direction of the RC vehicle 100 without the necessity to actually turn the RC vehicle 100.
Additionally, a particularly novel aspect of the present invention is that the RC vehicle 100 includes only two drive wheels, the right wheel 116 and the left wheel 118. Each of the wheels 116 and 118 are independently controlled by the receiver. By having only two drive wheels, each of which are independently controlled, the RC vehicle 100 is able to effectively turn in place, such that uni-engagement of the left 118 or right 116 wheels alone causes the RC vehicle 100 to turn, and bi-engagement of both the right 116 and left 118 wheels in opposite directions also causes the RC vehicle 100 to turn. Furthermore, bi-engagement in the same direction (i.e., either forward 210 or reverse 218) causes the remotely controlled car to propel itself forward 210 or reverse 218 (which causes the stabilization apparatus 208 to flip over the top of the RC vehicle 100 as described above), thereby allowing a user to maneuver the RC vehicle 100 in forward 210, reverse 218, left 222, and right 224 directions.
The rod 300 (and stabilization apparatus 208) has an outer portion 302 with at least two stabilization wheels 304 rotationally attached with the outer portion 302. A washer 305 may be included between the stabilization wheels 304 to assist the wheels in spinning. The stabilization wheels 304 allow the RC vehicle 100 to easily roll across a surface without having to drag any point of the vehicle 100. Additionally, because the RC vehicle 100 is propelled by the front two wheels only, stabilization wheels 304 in the rear enable the RC vehicle 100 to turn more easily.
Side rods 306 may also be included to prevent side-to-side sway of the rod 300. An antenna 308 is circumferentially disposed around the rod 300. The antenna 308 allows the RC vehicle 100 to pick up signals from an RC transmitter and pass the signal on to the receiver.
In another aspect, the antenna 308 can be formed to operate as a spring to force the stabilization wheel 304 away from the body member 102, thereby minimizing impact forces against the body member 102 when coming in contact with a surface. To enable the stabilization apparatus 208 to move, the body member 102 includes at least one sleeve 309. The sleeve 309 allows for insertion of the rod 300, thereby providing for a slide-able rod 300 inserted within the body member 102 and creating the movable connection. In this aspect, the side rods 206 also move within sleeves 310 formed on the body member 102.
In another aspect, not shown, the stabilization apparatus 208 may simply be an extension of the body member 102, such that the extended portion extends beyond the peripheral portions 120 of the wheels 116 and 118 to engage with the supporting surface, thereby preventing the body member 102 from spinning around itself as described above. Essentially, the stabilization apparatus 208 is any suitably rigid protrusion that is connected with the body member 102 and protrudes beyond the peripheral portions 120 of the wheels 116 and 118 proximate the rear portion. As described herein, the stabilization apparatus 208 can be an extension of the body member 102, or be another apparatus attached with the body member 102 to extend beyond the peripheral portions 120.
Also shown in
Additionally, when the motors are actuated in a counter-clockwise direction 214 to propel the RC vehicle 100 in reverse 218, an upward force 220 is applied to the stabilization apparatus 208, thereby flipping the stabilization apparatus 208 up and over to the opposite side of the RC vehicle 100 until it comes to rest against the supporting surface 500 on the other side of the RC vehicle 100.
As shown in
As can be appreciated by one in the art, although the quick release apparatus 700 is shown on the front portion 112, it can be placed at any suitable location on the body member 102 to provide for ease of access and quick release of the wheels 116 and 118.
In addition to changing the wheels for aesthetic purposes, different interchangeable wheels provided a variety of functional differences. For example, on asphalt, a smooth wheel is appropriate, providing proper traction and speed for the RC vehicle 100. When used in mud however, the smooth wheel may spin in the loose surface. Accordingly, as shown in
As shown in
As can be appreciated by one skilled in the art, the present invention also comprises a method for forming the remotely controlled vehicle described herein. The method includes acts of forming a body member 102; rotationally mounting a detachably attachable right wheel 116 proximate the right portion of the body member 102; drivably coupling a first motor 200 with the right wheel 116; rotationally mounting a detachably attachable left wheel 118 proximate the left portion of the body member 102; drivably coupling a second motor 202 with the left wheel 118; attaching a receiver 206 with the body member 102; and attaching a stabilization apparatus 208 with the body member 102.
(2.2) Detailed Description of the Launcher
As noted above, the wheels 116 and 118 described herein are detachably attachable. Because of their detachability, the wheels can also be used in other devices. Accordingly, the present invention also includes a launcher to launch the detachably attachable wheels. As shown in
The launcher 1100 has a housing 1106 with an opening 1108 passing through the housing 1106. The housing 1106 also includes a top surface 1111 on which a rotating end 1112 protrudes. A handle 1114 is included to allow a user to securely grasp the launcher 1100.
The strip 1102 (i.e., ripcord) has teeth 1116 on one side of its longitudinally extending strip like surface. The strip 1102 is formed to be passed through the opening 1108 in the housing 1106 and engage with gears therein.
The detachably attachable wheel 1104 includes a central rotor 711 that is formed to be attached with the rotating end 1112. As a non-limiting example, the central rotor 711 includes a hollow space 1118 for placement of the rotating end 1112 therein. Additionally, a wheel engagement apparatus 1120 is formed to engage with a corresponding rotating-end engagement apparatus 1122, such that as the rotating end 1112 rotates, the rotating-end engagement apparatus 1122 engages with the wheel engagement apparatus 1120 to cause the detachably attachable wheel 1104 to spin.
Both the rotating end 1113 and Gear B's rotation is slow when the strip 1102 is slowly inserted into the housing 1106. When the strip 1102 is pulled from the housing 1106, all the gears in the gear system 1300 work. When the strip 1102 is pulled from the housing 1106, Gears A1 and A2 rotate. Gear A2 drives Gear B, which causes the rotating end 1113 to rotate. The gears will continue to rotate as the strip 1102 is pulled out of the housing 1106 and away from the gear system 1300. As the gears rotate, the rotating-end engagement apparatus 1122 causes the detachably attachable wheel to spin off of the rotating end 1113 and away from the housing 1106.
Additionally, a wheel engagement apparatus 1120 is formed to engage with a corresponding rotating-end engagement apparatus 1122, such that as the rotating end 1113 rotates, the rotating-end engagement apparatus 1122 engages with the wheel engagement apparatus 1120 to cause the detachably attachable wheel 1104 to spin.
Alternatively and as shown in
For further clarification,
It should be noted that the gear system described herein references a specific gear configuration for illustrative purposes only, and that it is not intended to be limited thereto. As can be appreciated by one in the art, there are many gear system configurations that can be utilized to cause the detachably attachable wheel to spin away from the launcher.
This application is a non-provisional application, claiming the benefit of priority to provisional application No. 60/604,283, filed in the United States on Aug. 25, 2004, titled, “Wheel Spinning Launcher and Wheel Toy.”
