Accordingly and in order to secure mount member 20 to planar member 14 a user simply places the bottom portion 26 on ledge portion 24 and then move the upper portion 32 towards feature 30 of planar member 14. Once in this position the mount member is secured to the planar member, which in turn is secured to the wall via the removable adhesive. Accordingly, through the use of a removable adhesive planar member 14 can be secured to the wall in a variety of locations which will provide for numerous track configurations as will be discussed herein.
In addition, the releasable securement of mount member 20 to planar member 14 also provides for a breakaway feature wherein excessive forces in the direction of the arrow 34 will cause mount member 20 two become disengaged from the planar member prior to the planar member being torn away from the wall such that damage to the wall will be prevented. Accordingly, this wall mount will provide a user with a mechanism that can be releasably secured to various locations upon a wall without damaging the same.
Still further, mount member 20 further comprises a vertical wall portion 36 and a horizontal mounting portion 38 extending therefrom. In one embodiment, vertical wall portion 36 comprises bottom portion 26 and upper portion 32. As will be discussed herein, horizontal mounting portion 38 provides a means for securing track segments to the mount member 20. Although described as a horizontal mounting portion, portion 38 does not necessarily have to be positioned in a horizontal manner once mount member 20 is secured to planar member 14 since planar member 14 itself may be secured to the wall in an angular configuration.
In one application the configuration (e.g., width and height of the horizontal mounting portion) allows for a track segment 40 to be slidably secured to the horizontal mounting portion. In addition, the horizontal mounting portion is configured to have a uniquely shaped aperture 42 that is configured to receive a complimentary uniquely shaped feature 44 secured to a bottom surface of a track segment 46. In one non-limiting exemplary embodiment, aperture 42 and feature 44 are configured to have a cross or plus (+) shape configuration. Of course, any other suitable configuration is considered to be within the scope of exemplary embodiments of the present invention and the same is not limited to the specific configurations illustrated herein. Since wall mount 10 will be used for mounting tracks to a vertical surface such as wall 16 feature 44 is particularly useful in that the track segment must be pushed down vertically in order to engage the aperture and the horizontal mounting portion and the feature by virtue of its extending from a bottom surface of the track will prevent the track itself from sliding off of the horizontal mounting surface due to horizontal or angular movement of the track with respect to the horizontal mounting surface.
Mount member 20 further comprises a plumb bob indicator 50 that is pivotally mounted to the mount member. Plumb bob indicator 50 is positioned over an integrally molded feature 52 that includes an arrow portion 54 which corresponds to a vertical orientation of the mount member. Accordingly and since the plumb bob indicator is pivotally mounted to the mount member when the mount member is mounted to a surface in an angular configuration (e.g., other than vertical or 90° with respect to a horizontal line) the plumb bob indicator will be offset from feature 52 and in particular arrow portion 54. A free end 56 of the plumb bob indicator will be configured to have an arrow portion such that when the free end is offset from arrow portion 54 the arrow portion of the free end of the plumb bob indicator will provide a means for indicating whether it be mount member has been secured to the wall with an inclination to either the right or left.
As will be illustrated herein a plurality of mount members will be used to secure track segments to a wall in a variety of configurations such that toy vehicles traveling thereon will be able to traverse the track segments. In order to achieve this the track segments will have to be mounted to the wall in an angular fashion such that gravity will be able to pull objects or toy vehicles down the track segments. By locating a plumb bob indicator on the mount member a quick and convenient means for determining whether the mount member has been releasably secured to the wall with an angular inclination to either the right or the left will be provided.
Accordingly, a standalone mounting system for mounting a plurality of track segments to a wall is provided. In one embodiment the mounting system comprises a plurality of wall mounts as described above. Still further in at least one of the wall mounts or all of them or a portion of them will include a plumb-bob indicator showing the appropriate angle of the track secured to the mounting system. In addition, the mounting system will include a bracket and track connector wherein the system will have a breakaway feature that allows the track connector to be removed (intentionally or inadvertently) from the bracket secured to the wall upon the application of a predetermined amount of force. For example, a lip feature at the top of the bracket is configured to retain a top portion of the track connector while a bottom portion of the track connector is seated on a ledge or lip of the bracket. This feature will limit inadvertent damage to walls and also allows the track connector to be removed and replaced without completely removing the underlying attachment member of the bracket, which in one embodiment is any suitable fastener such as double sided adhesive tape.

In this embodiment, the 180° turn is provided by a zigzag track segment 204 that eventually redirects the toy vehicles into a spring or elastically loaded loop system 206. The spring loaded or elastically loaded loop system, which when loaded propels the toy vehicle or object through a loop 208 via an arm 210 or alternatively when the loop is not loaded the toy vehicle or object with pass through the segment without traversing the loop. In this embodiment, the spring loaded arm is released by a release mechanism that is actuated by a vehicle that traverses through the loop system and thus the car is propelled by the arm. Alternatively, other equivalent mechanism may be utilized to launch vehicles into the loop. In one embodiment the loop system, the loop and the arm are configured such that after arm 210 is triggered and if it is not reset to propel another vehicle through loop 208, the next vehicle can travel down the track by traveling through a lower portion 211 of the loop system and continuing on. The loop system or arm is reset by hand and can be reset before the next car is released or alternatively the loop system and arm can be left sprung and all following vehicles take the lower dip section 211 of the loop system.
Thereafter, the vehicle may travel to yet another feature of the track set via a diverter 212 that allows a user to select from at least two different track options one of which may terminate at a finish line 214 while the other allows the vehicle to traverse on to yet another track segment. Still further yet another diverter 216 is provided that allows the user to select from a lower track 218 that is positioned on a floor surface 219 or an upper track segment 220 that is still secured to the wall. In this embodiment track segment 220 has a plurality of pivotally mounted portions 222 that can be positioned or spring biased into an upward configuration wherein the vehicle passing therethrough may push the segments down such as it travels through track segment 220. Thereafter and after the vehicle passes portions 222 will spring back up such that they are in place for a subsequent vehicle to make contact with them and once again push them down. Thus portions 222 are spring loaded and once a vehicle hits the bridge section and causes the bridge section 222 to lie down and then passes over the bridge. Once the vehicle passes therethrough, the bridge sections 222 pop back up and the next vehicle. In an alternative embodiment, the portion are not spring biased and are merely pushed down by a lead vehicle such that a vehicle subsequently traveling down this track path will move therethrough at a fast rate since it does not have to knock down the pivotally mounted track portions 222. Still further, track segment 220 can be coupled to another end segment 224. As in the previous embodiments, a paper-template mounting system 120 is provided.
In each of the illustrated embodiments it is understood that the series of events or stunts located between each of the various stunt elements (track diverters, collapsible bridges, jumps, loops and other stunts included in the track path) as well as the reversal devices (180 degree turn); flipping devices (360 rotation about a toy vehicle axis); and a combination flipping/reversal device, can be rearranged in a plurality of sequences and/or parallel paths to provide numerous play patterns. For example, each of these items may be interchanged from set to set or within each set, in this way, a user can experience diverse track play and excitement time and time again.

More specifically, the embodiment of
The first track segment 310 further comprises a facade 330 resembling scenery such as a dock and portions 328 resemble flames that appear to be chasing the vehicle as they pop up behind the vehicle as it passes the various triggers along the track. Still further, the U-turn segment 316 features an enclosed twist tube, that rotates the vehicle about 180° in the horizontal axis, while allowing the vehicle to descend in the vertical axis (without flipping the vehicle on its roof). This tube accomplishes this by rotating the vehicle about 180° along the horizontal axis of the length of the vehicle (Y-axis), while simultaneously rotating the vehicle about 180° along the horizontal of the width of the vehicle (X-axis). Thereafter, the vehicle exits the twist tube and travels along a twisting segment 318 until it comes into contact with outlet portion 320.

As illustrated, vehicles 72 are launched into the gap 416 in the direction of the arrow 417 by booster 411 such that they can be received onto the second track segment 420 via a hood or guiding member 422, which is coupled to inlet member 418 of track segment 420. Guiding member 422 diverts vehicles traveling from ramp member 414 into track segment 420. In one embodiment, hood or guiding member 422 is manufactured out of a translucent material such that a user can see the vehicles or objects contacting guiding member 422.
Once an object or toy vehicle is launched into gap 416 from ramp member 414 it is received into track segment 420 by guiding member 422. Therefore, the vehicle travels towards a U-turn segment 424 which is configured to cause the vehicle to reverse its direction of travel in the horizontal direction while also traveling downwardly. U-turn segment 424 will direct the object or toy vehicle into another track segment 426 which terminates in an upwardly end portion 428 such that the vehicle will once again be launched into gap 416 from end portion 428. As illustrated, end portion 428 is proximate to the end portion of ramp member 414 and is configured to launch a vehicle into gap 416 towards an inlet member 430 of the first track segment 410.
Accordingly, a vehicle or object being launched from track segment 426 will travel into gap 416 in the direction of arrow 431 and if unobstructed will be received within inlet member 430 of first track segment 410. Similar to the second track segment 420, the inlet member 430 of the first track segment 410 also has a guiding member 432 configured to guide the objects or vehicles onto the first track segment. Once again, guiding member 432 may also be constructed out of a translucent material such that a user can see the vehicles contacting guiding member 432.
In one embodiment, multiple vehicles are capable of traversing along different portions of track set 400 such that multiple vehicles may be traversing along the tracks that at the same time. Once the vehicles or objects are received into the first track segment from gap 416 they are directed towards booster 411 such that they can, once again, be launched into gap 416 from ramp member 414 in the direction of arrow 417. As illustrated, arrows 417 and 431 depict paths of travel which may intersect with each other and if a vehicle is launched from end portion 428 of track segment 426 at the same time another vehicle is launched from ramp member 414 the vehicles will collide midair in gap 416 (see
In addition, U-turn segment 424 further comprises an inlet portion 425 that is configured to be coupled to other track sets which may or may not be secured to wall 16. Similarly, the inlet end 412 of the first track segment 410 is also configured to be secured to another track segment, which may or may not be secured to wall 16. First track segment 410 can also be configured to have a diverter member 427 that is pivotally secured to first track segment for movement between a first position and a second position wherein vehicles traveling along the first track segment will be directed towards booster 411 or alternatively away from booster 411.
Accordingly, this embodiment provides a wall track set that has an overhead vehicle booster configured to launch vehicles vertically from an upwardly facing jump ramp 414 wherein the vertically launched vehicles are captured by a catch or guiding member 422 incorporating a one-way flap 423 which redirects and reduces the speed of the incoming vehicle. Still further, the track set includes a diverter on the first track segment which allows the vehicle to return to the booster 411 and be launched into the gap 416, creating crash opportunities, or alternatively redirecting the vehicle to a gravity driven track set. An additional feature of this embodiment is that certain track segments or portions are configured to be attachable to various other track sets. For example, both the entrance end and exit end of the track set are configured to be coupled to track segments of other track sets, which may or may not be mounted to the wall the track set is secured to.

As illustrated, the second lower track section directs the toy vehicles 72 towards a bottom portion of a tower 513. As illustrated, the tower 513 has a corkscrew 515 rotationally secured to the tower 513. Corkscrew 515 is coupled to a motor 517 illustrated by the dashed lines in
As illustrated, a portion of the first upper track section has a diverter 523 pivotally mounted thereto for movement between a first and a second position, wherein one of two possible track paths down the first upper track section can be selected. Of course, numerous track configurations are contemplated. A first one of the two possible track paths includes a U-turn track section that redirects the vehicles 72 towards a starting gate 525. The starting gate 525 is pivotally mounted to the track segment for movement between a closed stopping position and an open release position wherein a user can stop the vehicles 72 at gate 525 and then manually release the gate 525 to allow the vehicles to travel towards the lower portion of tower 513 and corkscrew 515. In an alternative embodiment, gate 525 is set to trigger or move from a blocking position to an unblocking position when a predetermined amount of vehicles 72 are stacked behind the gate 525 (e.g. the weight of the vehicles backed up triggers the gate and allows at least one vehicle to pass therethrough).
Also shown between gate 525 and the bottom of the tower 513 proximate to the corkscrew 515 is a chomping device 527 comprising an upper jaw portion 529 pivotally mounted to a lower jaw portion 531. In one embodiment, the upper jaw portion 529 is linked or coupled to the motor driving corkscrew 515 or is coupled to the corkscrew 515 such that energizing of the motor and/or rotation of the corkscrew causes the upper jaw portion to pivot with respect to the lower jaw portion to resemble a chomping or biting action of the chomping device 527.
As the chomping device 527 reciprocates between an open position and a closed position, a user of the track set will try to time the release of the vehicles 72 from the gate 525 such that the vehicles 72 will pass through the chomping device when it is in an open position. If the timing is off the vehicles are captured by the chomping device and deposited in a hopper 532 of the chomping device. Vehicles captured in the hopper 532 of the chomping device 527 can be released through movement of a trap door 533 coupled to a release lever 535. Alternatively, trap door 533 may open due to the weight of the vehicles being captured in the hopper 532.
As illustrated, an alternative path from the top of the tower 513 to the corkscrew 515 at the bottom of the tower is provided. This alternative path further comprises a jump or gap 537 located therein wherein one end of the track path at one end of the gap 537 is higher than an opposite lower end of the gap 537 such that vehicles travelling down this path will jump across the gap 537. However and to add intrigue and random chance to the track set an obstacle 539 is pivotally mounted to the tower for movement between a first blocking position and a second non-blocking position in the directions of arrows 541.
In order to facilitate this movement an arm member 543 extends from the obstacle 539 and contacts the corkscrew such that rotation thereof will cause the pivotal movement of the obstacle 539 between the blocking and non-blocking positions as it engages the surfaces of the rotating corkscrew. Accordingly and if the obstacle is in the blocking position, a vehicle 72 attempting to jump the gap 537 will contact the obstacle 539 and the vehicle will not traverse the gap 537. Down the track from the obstacle is another starting gate 545 pivotally mounted to the track such that cars 72 that have traversed the gap 537 can be received at the bottom of the gate of the track set 510 and thus, manually launched towards the bottom of the corkscrew and picked up by the same and moved towards the top of the tower 413.
In addition and in one non-limiting embodiment, a track section 555 proximate to the bottom of the corkscrew is pivotally mounted to the track set such that is may pivot up and down as the corkscrew is rotated.
Track set 510 also has inlet or outlet portions 549 linked to the track sections such that the track set 510 can be connected to other track sets or vehicles may simply be added to the track set. In one embodiment, another pivotally mounted diverter 551 can be secured to the track set 510 proximate to the track paths and inlet or outlet portions.

As illustrated, the first upper track section 710 is separated from the second lower track section by a gap 713 that is traversed by a vertical U-turn device 715. The U-turn device 715 includes a carriage 717 for capturing the vehicle 72 from the upper track 710 and transports the vehicle about 180 degrees in the vertical axis to release the vehicle onto the lower track section 712 in an inverted manner. In one exemplary embodiment, the carriage 717 is biased towards the upper track section 710 by a resilient member or spring, and uses the momentum of the vehicle 72 travelling down the gravity track to actuate the U-turn device 715 such that movement in the direction of arrows 716 is possible.
Carriage 717 of the U-turn device 715 is configured to releasably retain and subsequently release the vehicle 72 as the U-turn device travels from the upper track section 710 to the lower track section. The carriage 717 may also incorporate a cage or shroud at least partially encapsulating the vehicle 72, for retaining the vehicle on the carriage in transit.
As illustrated, a cage or shroud 719 is located on the inlet portion of track section 712 to facilitate smooth transition of the vehicle from the upside down orientation when released. In one non-limiting exemplary embodiment, the U-turn device 715 has a structural member 721 secured to each of the upper and lower track sections 710, 712 and/or the wall mounts 10 secured thereto to provide stability to the track set 700.
In one non-limiting configuration, the upper track section 710 is provided with movably mounted start gate 723 that can be depressed into an aperture in the track such that a vehicle or object can roll down the first track section towards the U-device 715.
In accordance with an exemplary embodiment and as with all of the aforementioned track sets this track set can be mounted as a stand alone set or be combined with other wall mounted track sets.

In addition and in one embodiment, the triggers are further configured that only one trigger will be actuated during each race. Still further, the pair of triggers are configured (e.g., a portion thereof is located in the vehicle path) to be contacted by an incoming vehicle 72. Triggers 805 and 807 can be any type of reloadable triggers known to those skilled in the related arts wherein movement of the trigger from one position to another position releases a catch that allows a trap door to open. The trap doors 809 and 811 are pivotally secured to the track segment and may move to the open position via gravity or a spring biasing force or a combination thereof.
For example and during a race, a movably mounted start gate 823 for each lane can be depressed into an aperture in the track via a lever 825 such that a vehicle or object can roll down the track section towards the triggers 805 and 807. Once the start gate is used to start the race, the race starts and the two vehicles start traversing down the track segment along their respective paths each of which may include curves 827 and gaps 829 for jumping and the first one of the pair of toy vehicles 72 to traverse from the a first path of travel will actuate one of the pair of triggers and open the releasable trap door in front of a second one of pair of toy vehicles traversing in a second path of travel such that the second one of pair of toy vehicles to traverse from the first track segment to the second track segment will fall through an opening in the second track segment while the first one of the pair of toy vehicles to traverse from the first track segment to the second track segment will pass through an exit end of the second track segment. Accordingly, the winner of the race is the first vehicle to traverse the gap and contact one of the triggers thus opening a trapdoor in front of the other vehicle or loser of the race such that the losing vehicle falls through the opening in the track.

The platform 901 is coupled to the base 903 by at least one arm 915 pivotally coupled to the platform 901 at one end and pivotally coupled to the structure or base 903 at an opposing end. This pivotal securement of the arm or arms 915 allows the swing apparatus to rotate about 180 degrees in the vertical axis, while the horizontal pitch of the platform remains unchanged. The momentum of the vehicle travelling into the swing apparatus or onto the platform 901 from track segment 907 of the track set actuates the 180 degree swinging motion, while keeping the vehicle substantially upright. At the conclusion of the 180 degree rotation, the centrifugal force created by the rotating swing is translated to drive the vehicle 72 off the swing apparatus 715 and onto a different portion (second track segment 911) of the track set. The platform may be configured with a stop feature 917 at one end of the platform to prevent the vehicle from travelling off while the other end of the platform is open to allow ingress and egress of the vehicle 72 thereon.
In alternative embodiments, the swing apparatus may be configured to traverse another axis, or combination of axes, while employing the momentum of the vehicle to actuate the swinging motion.
In accordance with an exemplary embodiment and as with all of the aforementioned track sets each track disclosed herein set can be mounted as a stand alone set or be combined with other wall mounted track sets.
