FIELD OF THE INVENTIONThe invention relates generally to toy vehicle track sets and more particularly to loop apparatus utilized therein.
BACKGROUNDToy vehicle track sets in which self-powered vehicles are used are a popular and long-lasting category of toys. In some instances, such toy vehicles are powered by wind-up motors, electric motors, or inertial motors. In other instances, popular non-motorized toy vehicles include toy vehicles to which a velocity has been imparted such as, by the toy vehicle traveling a down sloping acceleration ramp at the entrance to the guided track or by placing the toy vehicle in a launcher, for example a spring loaded launcher that exerts a force on the toy vehicle. As toy vehicle track sets become more competitive, developers have sought to enhance the amusement and entertainment value of such toy vehicle track sets by including a variety of features. These features are sometimes referred to as “stunt devices”. These stunt devices include a wide variety of track segment loops, jumps, collision apparatus and the like. Track loops are particularly popular enhancements to toy track sets. Examples of toy vehicle track sets containing such enhancements and stunt devices include U.S. patents U.S. Pat. No. 6,089,951, U.S. Pat. No. 5,234,216, and U.S. Pat. No. 6,241,573, and published United States Applications US20070293122 and US20080020675, assigned to the assignee of the present invention, each of which is hereby incorporated by reference in their entirety for all purposes. Examples of toy vehicle track sets include U.S. Pat. Nos. 6,508,179, 6,358,112, 5,643,040, 4,558,687, 4,575,350, 4,558,867, 4,496,100 and published United States Application US20070293123, assigned to the assignee of the present invention each of which is incorporated by reference in their entirety for all purposes.
Multiple loops and interlocking loops are popular especially for non-motorized toy vehicle track sets. Loops may serve to increase the toy vehicle's speed and therefore increase the excitement of the entertainment provided by the toy vehicle. Existing toy vehicle tracks for non-motorized toy vehicles generally include full loops or loops with only minor interruptions. Because non-motorized toy vehicles generally move only due to external forces imparted upon them, there are limited ways to increase the speed and or entertainment value of such toys. Moreover, interruptions along the track length often result in the toy vehicle becoming displaced from the track thereby ending the instant play session.
A substantial number of toy vehicle track sets utilize one or more loop portions to increase the amusement and entertainment of the user. Some toy vehicle track sets utilize loop portions in the track, which define a gap rather than a continuous loop. In such instances, the gaps are intended to be traversed or “jumped” by high-speed toy vehicles within the track set. However, the size of the gap that may be used for non-motorized toy vehicle track sets is limited by the speed of the toy vehicle.
While there are a vast variety of track sets with loops and other stunt devices, there is still a need and demand for toy track sets that provide novel entertainment mechanisms. Embodiments of the present invention provide a novel virtual track loop for use with non-motorized toy vehicles. Embodiments of the present invention include a novel mechanism that causes a toy vehicle to travel in a nearly complete loop, using the vehicle's kinetic force combined with spring force, without the need for a complete track.
SUMMARYIn accordance with a preferred embodiment of the present invention, a toy vehicle track set is provided, the track set includes: a track segment with a first end and a second end; a base coupled to the first end of the track segment, the base including an entrance ramp and an exit ramp; a pillar having a first end and a second end; the first end of the pillar coupled to the base; an arm rotatably coupled to the second end of the pillar by an arm axle near the proximal end of the arm, such that the arm is free to rotate in a vertical loop; and a toy vehicle cage coupled to the platform at the distal end of the arm.
In another embodiment, a toy vehicle track set base is provided, the base includes a substantially level undersurface; an upper surface defining two ramps; a first ramp having an arm lock to secure a spring-loaded rotatable arm; a second ramp having a release mechanism to cause a gate on a toy vehicle cage located at the distal end of the spring loaded rotatable arm to open; and a foundation frame laterally coupled to the upper surface, the foundation frame supporting a pillar having the spring loaded rotatable arm with a toy vehicle cage coupled at the distal end of the pillar.
In addition a method of play for a toy vehicle track set is provided, the method of play includes loading a spring-loaded arm and cage assembly; propelling a toy vehicle toward the arm and cage assembly such that the toy vehicle enters the cage; releasing an arm lock such that the spring loaded arm and cage assembly rotate in a loop engaging a catch mechanism to stop the rotation of the loaded arm and cage assembly; and releasing the toy vehicle from the cage.

By way of overview, embodiments of the present invention utilize an arm with a toy vehicle cage at its distal end, coupled to a pillar that enables the arm to travel in a vertical loop.
FIG. 1 is a perspective view of an embodiment of a toy track set100. Thetrack set100 is designed to be used with non-motorized toy vehicles. A straightelongated track segment160 is coupled to atoy vehicle launcher170 at afirst end162 and to a base150 at asecond end164. Although shown as a single-track segment, it is contemplated within the scope of the embodiments of the present invention that multiple track segments could be utilized by interconnecting the segments using coupling means known in the art. Furthermore, although depicted as a straight track segment, this is not intended to be a limitation on the embodiments and other geometries are contemplated within the scope of the embodiments. In addition, although depicted as having atoy vehicle launcher170 at oneend162 of thetrack segment160, this is not intended to be a limitation on the embodiments of the present invention. Other means of placing a toy vehicle in motion are contemplated within the scope of the embodiments, including but not limited to a sloping acceleration track segment ramp, a track loop causing toy vehicle acceleration, a spring-loaded wheel system within the toy vehicle, and human-imparted velocity.
Thesecond end164 of thetrack segment160 is coupled to anentrance ramp152 of thebase150. Apillar140 is located adjacent to the base150 on the side opposite theentrance ramp152. At theproximal end112 of thepillar140, there is an opening (not shown) configured to accept anaxle arm130. Theaxle arm130 couples anarm110 to thepillar140. Thearm110 has atoy vehicle cage120 located at itsdistal end114.
Optionally included with the toy vehicle track set is atarget180. Thetarget180 is not coupled to thebase150 and may be placed anywhere in proximity to thebase150. The target is placed at a distance such that a toy vehicle exiting the track set may strike or land in the target. For example, in use the target may be placed approximately 24 inches or closer to the track set to catch the toy vehicle. Thetarget180 may be a container with a backstop and is designed to stop or catch and contain a toy vehicle when implemented with the toyvehicle track system100.
The various components of the toy track set100 may be comprised of plastic or any other suitable material and are fabricated in accordance with conventional fabrication techniques.
FIG. 2 is a breakaway view of the loop system ofFIG. 1. Theloop system200 provides for a toy vehicle to travel in a nearly complete loop without the need for a track segment while still providing a track set that is easily storable. The various components are designed to be alternatively assembled in either an operative configuration or storage configuration.FIG. 2 shows an exploded view of theloop system200 in which thebase150,pillar140,arm110,arm axle130 andvehicle cage120 have been separated one from the other disassembling the configuration previously described inFIG. 1. The elements shown inFIG. 2 may be easily stored when the track set is not in use.
FIG. 3 is perspective view of thebase150 of theloop system200. Thebase150 has a substantially level undersurface and an upper surface defining two ramps, anentrance ramp302 and anexit ramp304 offset from theentrance ramp302. A track segment, such as the track segment160 (not shown) described inFIG. 1 is coupled to theentrance ramp302. Theentrance ramp302 and theexit ramp304 are preferably constructed such that the cross section of theentrance ramp302 and the cross section of the exit ramp are substantially similar to the cross section of thetrack segment160. Theentrance ramp302 andexit ramp304 are constructed with sidewalls or curbs322,324 to help ensure a toy vehicle used with theloop system200 remains on the ramps. Theexit ramp304 extends the length of thebase150 and preferably has a curved shape. Theexit ramp304 more preferably is shaped as a portion of a loop. Adjacent to anouter edge306 of theexit ramp304 is afoundation frame308. Thefoundation frame308 may be positioned anywhere along the length of theouter edge306 of theexit ramp304, preferably however thefoundation frame308 is located half way to two thirds down the length of theexit ramp304.
Also located on thebase150 is alaunch block310. Thelaunch block310 is positioned along the same side and at the far end of theentrance ramp302. Thelaunch block310 is configured with anarm lock312 at itsfar end314 to mate with a gate on a toy vehicle cage as described below in detail. Thearm lock312 is attached to thelaunch block310 with alock axle316 and an opening and closing mechanism is controlled by alock torsion spring318. Theexit ramp304 is configured with arelease latch mechanism320 to mate with a gate on thetoy vehicle cage120 as describe below is detail. Therelease latch mechanism320 causes a gate on thetoy vehicle cage120 to open allowing the toy vehicle to exit thecage120. Thearm lock312 acts to hold thetoy vehicle cage120 in a start position (with a loaded coil spring force) described in detail below.
FIG. 4 is a detailed view of thearm110 of theloop system200 ofFIG. 2. Thearm110 has areceptacle404 designed to receive an arm axle fitting at oneend408 and aplatform406 at theopposite end402. Theplatform406 forms a base of a vehicle cage, described in detail below. When in place, thearm axle130 couples thearm110 to thepillar140. Theplatform406 is curved in shape and preferably has a similar or the same profile as theexit ramp304. Thearm110 acts as a pendulum to rotate thevehicle cage120, which holds a toy vehicle, located at thedistal end402 in a vertical loop. The opposite end of thearm110 is configured with areceptacle404 to receive an axle arm so that thearm110 may be coupled to a pillar.
FIG. 5 is a detailed view of thearm axle130 of the virtual loop system ofFIG. 2. Thearm axle130 has a fitting502 designed to mate with thereceptacle404FIG. 4 of thearm110. The fitting may be part of the cylindrical structure or it may be a separate piece. Thearm axle130 is a hollow cylindrical structure with aspiral grove504 along the outer surface of its length. Contained within thearm axle130 is acoil arm spring506. Thecoil arm spring506 is held within thearm axle130 by a pin508 at the fitting502 end of thearm axle130 and by aspring cap510 that is connected to the opposite end of thearm axle130. Thespiral grove504 mates with a pin (not shown) located within the opening at the distal end of thepillar140.
FIG. 6 is a detailed view of the toyvehicle cage assembly120 of the loop system ofFIG. 2. The toy vehicle cage assembly120 (“the cage”) may also be referred to as a carrier. Thecage120 enables a toy vehicle to be transported. Thecage120 is configured to attach to theplatform406 of thearm110. Thecage120 may be permanently affixed to theplatform406 or may be removable and attached by clips, screws, or any other coupling means. Preferably, thecage120 is sized so that a toy vehicle fits in thecage120 easily and can easily enter and exit the cage but should not be so wide as to allow a toy vehicle to rotate about within the cage. The toy vehicle cage is generally a hollow rectangular shape having smoothed corners, with the one side of the rectangle removed. The removed portion is however not limited to a complete side and the portion removed may be greater or less than that specified. Thecage120 has an inner surface and an outer surface. Thevehicle cage120 may have solid sidewalls or sidewalls with openings so that a toy vehicle contained within thecage120 is visible. Although described as rectangular in shape, this is not intended to be a limitation on the embodiments of the present invention, alternative geometries suitable to contain a toy vehicle are contemplated within the scope of the embodiments. The cage may be any elongated hollow structure that is sized to contain the toy vehicle. The toy vehicle cage preferably however surrounds all sides of the toy vehicle to ensure the vehicle does not fall out of the vehicle cage when in motion.
In another embodiment, the toy vehicle cage is constructed with an uninterrupted outer wall and is affixed to theplatform406. In still another embodiment, thearm110 does not have a platform and the vehicle cage is constructed with an uninterrupted outer wall and is affixed directly to the arm.
Afirst end602 of thecage120 is open and configured to receive a toy vehicle. Theopposite end604 of thecage120 is configured with acage gate606. The cage gate has atension tab608. Thecage gate606 is coupled to thecage120 with agate axle610. Atorsion spring612 maintains near constant tension on the cagegate tension tab608. Although depicted as having thecage gate606 coupled to thecage120 at the lower edge of thecage120, this is not intended to be a limitation on the embodiments of the present invention. It is contemplated within the scope that thecage gate606 may be attached at the upper edge of the opening at theend604 thecage120 or along either side of the opening of theend604. Similarly, the location of thetension tab608 may vary depending on the point at attachment of thecage gate606
FIG. 7 is a perspective view of the virtual loop system track set ofFIG. 1 in motion in accordance with an embodiment of the present invention.
Embodiments of the present invention provide a novel toy track set loop in which anarm110 having atoy vehicle cage120 rotates atoy vehicle702 in a loop and enables thetoy vehicle702 to make a stunt jump without a track. In operation, thearm110 is wound counterclockwise so that thecoil spring506 is in a stretched state and loaded with energy. Thecage120 is locked in place by thearm lock312 on theentrance ramp302. Thetoy vehicle702 is then set in motion. In the depicted embodiment, thetoy vehicle702 is launched from atoy vehicle launcher170. The energy from thelauncher170 is imparted to the toy vehicle to create kinetic energy.
Thetoy vehicle702 travels along thetrack segment160 to theentrance ramp302 and enters thecage120. The kinetic energy of thetoy vehicle702 causes thearm lock312 to release resulting in thearm110 traveling upward. Because thearm110 is fixed at one end, thearm110 travels in a circular motion. Thearm110 continues to travel in a clockwise direction as thecoil spring506 located in thearm axle130 returns toward its resting, non-stretched state. The spiral groove along thearm axle130 guides thearm axle130 through thereceptacle404 in thearm110 resulting in thearm110 traveling in a loop. The rotation of thearm110 is driven by both the energy imparted from the toy vehicle and the energy stored in thecoil spring506. Preferably, thearm110 travels clockwise approximately 320-340 degrees.
After thearm110 rotates 320 to 340 degrees, thevehicle cage120 comes in contact with theexit ramp304 where thecage tension tab608 contacts a release mechanism, which stops the rotation of the arm and thecage gate606 opens releasing thetoy vehicle702 onto theexit ramp304. The remaining approximately 20-40 degrees of the loop is provided by theexit ramp304 on the base.
Upon making contact with the exit ramp, thetoy vehicle702 is thrust from thecage120 and travels along or slightly above theexit ramp304 which terminates in an upwardly projecting ramp portion and from which the toy vehicle is launched in an airborne projectile path. The landing point of the toy vehicle varies as a function of the vehicle's pre-launch velocity. The prelaunch velocity may vary depending upon the speed in which thetoy vehicle702 initially entered thevehicle cage120.
When thetoy vehicle702 leaves thecage120, its velocity will cause it to traverse the plane ofexit ramp304 on thebase150. Thetoy vehicle702 once launched continues toward thetarget180 in a ballistic path. The toy vehicle will either miss the target entirely, impact a portion of the target and fall out outside of the target or impact the target at either aninterior wall704 orbackstop portion706 in which case thetarget180 may rotate backward, catching thetoy vehicle702.
The virtual loop system is preferably designed to release the toy vehicle from the cage such that it travels 6-24 inches horizontally from the virtual loop system to the target180 (FIG. 1). The toy vehicle preferably travels at a maximum vertical height of between approximately 6 and 9 inches above the surface on which the toy vehicle track set rests.
As noted previously the forgoing descriptions of the specific embodiments are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed and obviously many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to explain the principles of the invention and its practical applications, to thereby enable those skilled in the art to best utilize the invention and various embodiments thereof as suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
