CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims the benefit of Canadian Patent Application No. 3,177,813 filed Sep. 29, 2022, the contents of which are incorporated herein in their entirety.
FIELD
The present disclosure relates to toy tracks for toy vehicles, and more particularly to systems for lifting a toy vehicle on a vertically extending toy track, releasing the toy vehicle on the toy track, and selecting a stunt track segment for the toy track.
BACKGROUND OF THE DISCLOSURE
The prior art includes examples of toy tracks for toy vehicles: U.S. Pat. No. 3,542,366 (Schocker; Nov. 24, 1970); U.S. patent application publication no. 2005/0287918 A1 (Sheltman et al.; Dec. 29, 2005); U.S. Pat. No. 7,628,674 (Nuttall et al.; Dec. 8, 2009); U.S. patent application publication no. 2012/0220183 A1 (Payne; Aug. 30, 2012); U.S. Pat. No. 8,449,344 (Nuttall et al.; May 28, 2013); U.S. Pat. No. 8,567,690 (De La Torre; Oct. 29, 2013); U.S. Pat. No. 8,944,882 (O'Connor et al.; Feb. 3, 2015); U.S. Pat. No. 9,314,705 (Payne et al.; Apr. 19, 2016); U.S. Pat. No. 9,586,154 (Lau et al.; Mar. 7, 2017); and U.S. patent application publication no. 2018/0229137 A1 (Martinez et al.; Aug. 16, 2018). U.S. Pat. No. 7,770,811 (Belding; Aug. 10, 2010), U.S. Pat. No. 7,946,903 (Sheltman; May 24, 2011), and U.S. Pat. No. 10,265,634 (Daly et al.; Apr. 23, 2019) disclose toy vehicle tracks with vertically extending segments. The Hot Wheels™ Track Builder Vertical Launch Kit, model no. GGH70 (Mattel, Inc., USA) includes a toy track with a vertical segment that is removably secured to a wall using Command Strips™ (3M Company; USA).
A child at the age of six years old typically has a maximum reach of about 4 feet (3.7 meters). It would be desirable for such child to able to place a toy vehicle on and release the toy vehicle from the vertical track segment at a height beyond the child's reach.
U.S. Pat. No. 7,819,720 (Nuttall et al.; Oct. 26, 2010), and U.S. Pat. No. 8,323,069 (Nuttall et al.; Dec. 4, 2012) disclose a toy vehicle track with an indexing stunt selector having a first stunt element (i.e., a track segment) disposed in the vehicle pathway to cause a toy vehicle to perform a stunt. The stunt selector includes a turntable-like rotating element that rotates the stunt elements about a vertical axis that is perpendicular to the horizontal travel direction of the track for aligning one of the stunt elements with the remainder of the track. The Monster Jam™ Stunt Dial Playset, model no. 6060862 (Spin Master Corp.) includes a toy vehicle launcher and an indexing stunt selector. The stunt selector includes a Ferris wheel-like rotating element that rotates various stunt elements (i.e., track segments) about a horizontal axis that is perpendicular to the horizontal travel direction of the track for aligning one of the stunt elements with the remainder of the track.
Such stunt selectors require a substantial horizontal footprint or vertical clearance beyond the track surface to accommodate the rotation of the stunt elements. It would be desirable for stunt selectors to have a more compact configuration.

Toy Track System
FIG. 1 shows a system 10 of the present disclosure for use with a toy vehicle 12 that that travels on a toy track 14. The toy vehicle 12 may be a wheeled toy vehicle, such as a toy truck in the embodiment shown, and may therefore have a plurality of wheels 13, including a plurality of rear wheels 204 and a plurality of front wheels 206. The track 14 includes a segment 15 having an upper end. The segment is vertically extending. As used herein, “vertically extending” refers to the track 14 being oriented at a non-zero angle relative horizontal, such as about 80 degrees from the horizontal in the embodiment shown. An upper support member 16 supports the track 14 against a vertical surface 18 such as a wall or a door. A first lower support member 20 supports an intermediate portion of the track 14 on a horizontal surface 22 such as a floor or a table top. A second lower support member 24, in the form of stylized dinosaur feet, supports an end of the track 14 on the horizontal surface 22. In other embodiments, the track 14 may be “free standing”—i.e. supported entirely on the horizontal surface 22 such as a floor or a table top, without the need for support against a vertical surface such as a wall or a door. A stylized dinosaur head 26 houses batteries that power light-emitting diodes (LEDs) for generating lighting effects, a speaker for generating sound effects, and a motor for generating movements of the dinosaur head 26 to trap the toy vehicle 12. Accessories of the system 10 include a landing ramp 28, and a smart phone holder 30. The system 10 includes a carrier 40, a stop structure 60, a lifting apparatus 80, and a stunt apparatus 110, as described below.
Carrier
With reference to FIGS. 4-9, a purpose of the carrier 40 is to hold the vehicle 12 as the carrier 40 is lifted along the track 14. Another purpose of the carrier 40 is to release the vehicle 12 when the carrier 40 engages the stop structure 60.
The carrier 40 is movable between a lower position, which may also be referred to as a loading position, and an upper position, which may also be referred to as a launch position (FIG. 4). In the lower or loading position, the carrier 40 is positioned for the loading of the vehicle 12 therein. In the upper position or launch position, the carrier 40 engages the stop structure 60 so as to release the vehicle 12.
The carrier 40 includes a vehicle holder that is positioned for releasably holding the toy vehicle 12.
In embodiments, the vehicle holder may have any suitable structure positioned to releasably hold the toy vehicle 12. Referring to FIG. 4, in the embodiment shown, the vehicle holder of the carrier 40 includes a central member 42 with a pair of attached calipers 44. The central member 42 is attached to the track 14 by means of a protrusion on the underside of the central member 42 that inserts into an elongate gap 50 defined by the track 14. The calipers 44 include a first caliper arm 44a and an opposed second caliper arm 44b. Each caliper arm 44a and 44b defines a vehicle engagement surface 46. In this embodiment, each of the calipers 44 is pivotally attached to the central member 42. The pivotal attachment may be by a pin connection 48, thereby permitting the calipers 44 to pivot in the directions shown by the double-headed curved arrow lines. In other embodiments, only one of the calipers 44 may be pivotably attached central member 42, while the other one of the calipers 44 is fixedly attached to a central member 42. In still other embodiments, the individual caliper arms 44a and 44b of the calipers 44 may be pivotably attached directly to one another instead of individually being pivotally mounted to a central member.
Pivoting of the calipers 44 varies the distance between their respective vehicle engagement surfaces 46 such that the calipers 44 are movable between a vehicle holding position (FIGS. 5-8) in which the calipers 44 are positioned to hold the vehicle 12 by engagement with the vehicle engagement surfaces 46 with the caliper receiving surfaces 200 on the vehicle 12, and a vehicle release position (FIG. 9) in which the vehicle engagement surfaces 46 are disengaged from the caliper receiving surfaces 200 of the vehicle 12, so as to permit launching of the vehicle 12. The calipers 44 may be biased towards the vehicle holding position. More specifically, one or more caliper-biasing members 61 (e.g. such as one compression spring or one tension spring acting between the calipers 44, or a compression spring or a tension spring or a torsion spring for each caliper arm 44a, 44b, acting between the caliper arm 44a, 44b and an anchor point on the central member 42) may be positioned to urge the calipers 44 towards the vehicle-holding position. For example, the one or more caliper-biasing members 61 may include a first torsion spring in a first one of the calipers 44 and a second torsion spring in a second one of the calipers 44. As an example, a caliper-biasing member 61 is shown in the form of a first torsion spring in a first one of the calipers 44, in FIG. 7. It will be understood that a second torsion spring may be provided in the other of the calipers 44, even though not shown in the figure.
In use, when the carrier 40 is in the loading position as shown in FIG. 5, the vehicle 12 may be loaded on the carrier 40 in any suitable way, such as by translating the vehicle 12 along the track 14 such that the vehicle 12 engages the pusher surfaces on the ends 52 of the caliper arms 44a and 44b. This causes the caliper arms 44a and 44b to separate from each other. Once the vehicle 12 has been pushed into place the caliper biasing members 61 drive the caliper arms 44a and 44b to close such that the vehicle engagement surfaces 46 engage the caliper receiving surfaces 200 of the vehicle 12.
In the embodiment shown, the caliper receiving surfaces 200 are the walls of central wells, shown at 202 in the rear wheels, shown at 204, of the vehicle 12. Alternatively however, the caliper receiving surfaces 200 may be anywhere on the vehicle 12 such as in recesses on the vehicle body.
When the carrier 40 is in a vehicle-holding configuration as shown in FIGS. 6, 7 and 8, the opposed vehicle engagement surfaces 46 engage the tires of the vehicle 12. In this embodiment, the calipers 44 define shoulders 54 that are complementary in shape to the wheel of the vehicle 12. Engagement of the shoulders 54 with the wheel helps the calipers 44 to more securely hold the vehicle 12.
Alternatively, the calipers 44 may be biased towards the vehicle-holding configuration without the need for springs or the like, by their shape, such that gravity urges them towards the vehicle-holding configuration.
Stop Structure
A purpose of the stop structure 60 is to limit the travel of the carrier 40 on the track 14, and thus the “drop height” on the track 14 from which the vehicle 12 can be released. In embodiments, another purpose of the stop structure 60 is to actuate the carrier 40 from the vehicle-holding configuration to the vehicle-releasing configuration to release the vehicle 12 to roll down the track 14, as discussed above.
In embodiments, the stop structure may have different member(s) that are adapted to engage the vehicle holder of the carrier 40. Referring to FIG. 4, in the embodiment shown, the stop structure 60 includes a main stop structure body 62, a cam lever 64, a key member 66, and a pair of caliper-actuating members 68, as described below.
The main stop structure body 62 is attached to the track 14. The main stop structure body 62 is translatable along the toy track 14 to vary the position of the stop structure 60 along the toy track 14, but can be fixed in position using the cam lever 64 and key member 66. The cam lever 64 and the key member 66 are both associated with lock positions and unlock positions. In their lock positions as shown in FIG. 4, the cam lever 64 engages the underlying track 14 through an aperture defined by the main stop structure body 62. Friction between the cam lever 64 and the track 14 prevents translation of the main stop structure body 62 relative to the track 14. The key member 66 interferes with the cam lever 64 to prevent the cam lever 64 from pivoting from the lock position to the unlock position. In this manner, the key member 66 acts as a safety device. In order to adjust the position of the stop structure 60 along the track 14, the user moves the key member 66 to the unlock position by shifting the key member 66 leftward relative to the main stop structure body 62, as shown by the straight directional arrow 70 in FIG. 4. The key member 66 is shaped such that, in the unlock position, it permits pivoting moving of the cam lever 64. The user can then pivot the cam lever 64 downward relative to the main stop structure body 62 to the unlock position, as shown by the curved directional arrow 72 in FIG. 4. The cam lever 64 is shaped such that, in the unlock position, the cam lever 64 disengages from the track 14. The user can then slide the stop structure 60 along the track 14 to control the desired maximum “drop height” of the carrier 40, and then fix the position of the stop structure 60 by moving the cam lever 64 and the key member 66 to their lock positions. Referring to FIG. 3, for example, the stop structure 60 can be fixed in position on the track 14 to select a drop height of 4 feet (1.2 meters) or 6 feet (1.8 meters) above a horizontal surface 22 such as a floor.
Referring to FIG. 4, each of the caliper-actuating members 68 is associated with a different one of the pivotable calipers 44 of the carrier 40. In other embodiments of the carrier 40 having only one pivotable caliper 44, the stop structure 60 may have only one caliper-actuating member 68. In this embodiment, each of the caliper-actuating members 68 has an elongate triangular shape extending downward to a vertex. Referring to FIGS. 4, 7 and 8, the vertices of the caliper-actuating members 68 are positioned to engage sloped upper surfaces of the calipers 44 of the carrier 40. Referring to FIG. 9, the stop structure 60 is fixed in position along the track 14. As the carrier 40 moves up along the track 14 relative to the stop structure 60, the caliper-actuating members 68 urge the calipers 44 to pivot relative to the central member 42 of the carrier 40, in the direction shown by the curved arrows, into the vehicle-releasing configuration. This pivoting increases the distance between the opposed vehicle engagement surfaces 46, so that they disengage from the vehicle 12, and release the vehicle 12 to roll down the track 14.
Lifting Apparatus
A purpose of the lifting apparatus 80 is to lift the carrier 40 and the held vehicle 12 to the desired “drop height” on the track 14, and into engagement with the stop structure 60 so that the carrier 40 releases the vehicle 12 as described above. The lifting apparatus 80 may be used to lift the vehicle 12 beyond the reach of a user. Referring to FIG. 1, for example, the child 150 may use the lifting apparatus 80 within the child's reach to lift the carrier 40 and the held vehicle 12 to the upper end of the track 14 at about 6 feet (1.8 meters) above the horizontal surface 22.
FIG. 10A shows a schematic representation of a lifting apparatus 80. In this embodiment, the lifting apparatus 80 includes a support member 82, a drive wheel 84, a one-way clutch 85, and a carrier line 86. These and other parts of the lifting apparatus 80 are described below. FIGS. 11 and 12 show one embodiment of the lifting apparatus 80, and FIG. 13 shows another embodiment of the lifting apparatus 80.
The support member 82 may be provided to rotatably support the drive wheel 84. In other embodiments, the support member 82 may be omitted, if for example, the drive wheel 84 is directly attached and rotatably attached to the track 14. In embodiments, the support member 82 is positioned to hold the track 14. In the embodiment shown, the support member 82 is also adapted to bear against a vertical surface 18 such as a wall. FIGS. 11A, 11B and 12 show one embodiment of a support member 82 including three parts. The first part is a bracket 88 that has a planar surface that interfaces with the vertical surface 18. As shown in FIG. 11B, the bracket may be attached to the vertical surface 18 using strips of stretch releasing adhesive tape 89, such as tape marketed under the name Command Strips™ (3M Company; USA). The second part is a substantially triangular-shaped frame 90 that releasably attaches to the bracket 88 by interference fit of tabs defined by the bracket 88 that insert into corresponding slots defined by the frame 90. The third part is a truss 92 that releasably attaches to the frame 90 by interference fit of tabs defined by the truss 92 that insert into corresponding slots defined by the frame 90. In this embodiments, the support member 82 is disposed above the horizontal surface 22 (e.g., floor) that supports the track and does not contact the horizonal surface 22.
In the embodiments shown, the drive wheel 84 is rotatably supported by the support member 82. The drive wheel 84 is rotatable to pull the carrier line 86, which in turn drives the carrier 40 towards the launch position. In the embodiment shown in FIGS. 10A, 10B, 11A, 12 and 13, the drive wheel 84 is disposed horizontally adjacent to the vertical surface 18 of the wall, and more particularly, horizontally between the vertical surface 18 of the wall and the track 14. This is advantageous in that the drive wheel 84 does not impede the user's view of the track 14, and conserves space. Referring to FIG. 10A, the drive wheel 84 is rotatable in a first drive wheel direction D1, about an axis that is transverse to the elongate direction of the track 14.
The one-way clutch 85 may have any suitable structure. In the embodiment shown, the one-way clutch includes a plurality of teeth 98, which may optionally be near a periphery of the drive wheel 84. In the embodiment shown in FIGS. 10A and 10B, the teeth 98 extend across the entire thickness of the drive wheel 84. In the embodiment shown in FIGS. 11A and 12 the teeth 98 do not extend across the entire thickness of the drive wheel 84, but are instead flanked by a flange on one side thereof. A handle 87 is attached to the drive wheel 84 for manually rotating the drive wheel 84.
The one way clutch 85 further includes a pawl 85a that engages the plurality of teeth 98 on the drive wheel 84. Worded more broadly, a plurality of teeth 98 are driven to rotate due to rotation of the drive wheel 84. The pawl 85a is positioned to engage the plurality of teeth 98 to prevent rotation of the drive wheel 84 in a second rotational direction D2 that is opposite the first rotational direction. In the embodiment shown, the pawl 85a is positioned to be pushed away by the teeth 85b during rotation of the drive wheel 84 in the first rotational direction D1 (i.e. a counter-clockwise direction in the view shown in FIGS. 10A and 10B), which is the direction in which to drive the carrier 40 towards the launch position. Thus, the pawl 85a permits rotation of the drive wheel 84 in the first rotational direction D1. The pawl 85b is positioned to engage the teeth 85b thereby blocking rotation of the drive wheel 84, during rotation of the drive wheel 84 in the second rotational direction D2 (i.e. clockwise in the view shown in FIGS. 10A and 10B) so as to permit the user, while cranking the handle 87 to drive the carrier 40 towards the launch position, to let go of the handle 87 momentarily, without the carrier 40 falling all the way down to its bottom-most position. Then the user can regrip the handle 87 to continue rotating the drive wheel 84 in the first rotational direction D1 so as to continue driving the carrier 40 towards the launch position. When the pawl 85a is engaged with the teeth 98 to prevent rotation of the drive wheel 84 in the second rotational direction D2 (i.e. when the drive wheel 84 is attempted to be rotated in the second rotational direction D2), the pawl 85a may be said to be in a holding position (FIG. 10B). When the drive wheel 84 is rotated in the first rotational direction D1 and therefore the pawl 85a is positioned such that the pawl 85a permits the rotation of the drive wheel 84 in the first rotational direction D1, the pawl 85a may be said to be in a release position (FIG. 10A). Based on the above, the one-way clutch 85 may be said to permit rotation of the drive wheel 84 in the first rotational direction D1, and to prevent rotation of the drive wheel 84 in the second rotational direction D2.
While the one-way clutch operated by interference of the pawl 85a with the drive wheel 84, in other embodiments, the pawl 85a may instead resist movement of the drive wheel 84 by frictional engagement with the drive wheel 84 or with the carrier line 86. For example, the pawl 85a may be shaped in the form of a cam that is rotated into progressive tighter engagement with the drive wheel 84 or with the carrier line 86 by rotation of the drive wheel 84 in the second rotational direction D2, so as to stop further rotation of the drive wheel of the drive wheel 84 in the second rotational direction D2.
FIG. 13 shows another embodiment of a support member 82 that includes parts in the shape of a pair of stylized dinosaur feet 94 that bear against the vertical surface 18, and legs 96 that extend horizontally toward the track 14. In this embodiment, the legs 96 are attached to the track 14, and therefore the support member 82 at least partially supports the track 14. In still other embodiments, the support member 82 may have different forms.
The carrier line 86 may be a flexible member, with non-limiting examples being a cord, a string, a ribbon, a chain, a cable, or the like. The carrier line 86 is engaged with the drive wheel 84 and attached to the carrier 40. Referring to FIG. 10, the carrier line 86 may be routed around a sheave 100 or similar structured attached to the track 14 near its upper end. Such a sheave 100 may not necessary if the drive wheel 84 is disposed above the desired drop height of the vehicle 12. Referring to the embodiment shown in FIG. 13, the carrier line 86 is engaged with the drive wheel 84 by being tied to a stud 102 that is attached to the drive wheel 84. Referring to the embodiment shown in FIG. 14, for example, the carrier line 86 is engaged with the carrier 40 by being tied to a stud 104 that is attached to the carrier 40, and received in the gap 50 defined by the track 14. In other embodiments, the carrier line 86 may be engaged with the drive wheel 84 and the carrier 40 in different ways. For example, the drive wheel 84 may be attached to a winch drum connected to a drive wheel 84, and the carrier line 86 may be wound around the winch drum. In either case, when the drive wheel 84 is rotated relative to the support member 82 in the first wheel direction, the drive wheel 84 pulls the carrier line 86 to move in the first carrier line direction, which turns pulls the carrier 40 and the held vehicle 12 up the track 14.
Stunt Apparatus
A purpose of the stunt apparatus 110 is to allow a plurality of different stunt track segments to be selectively and individually aligned with the track 14. FIGS. 15 to 21 show one embodiment of a stunt apparatus 110. FIGS. 22 to 24 show different stunt track segments. The stunt apparatus 110 includes a plurality of stunt track segments attached to a rotary indexer 142, as described below.
As used herein, a “stunt track segment” refers to a segment of toy track that is adapted to induce a motion of the vehicle 12 when the vehicle 12 travels over the stunt track segment. The plurality of stunt track segments may be any integer number of stunt track segments greater or equal to two stunt track segments. In the embodiments shown in the Figures, the stunt apparatus 110 includes three stunt track segments. As shown in FIGS. 18 and 22, a first stunt track segment 112 has an upwardly curved ramp surface for inducing a “high arc” jumping motion to the vehicle 12 as shown by the curved arrow line 113. As shown in FIGS. 19 and 23, a second stunt track segment 114 has a first portion 116 and a second portion 118 pivotably connected thereto by a pin 120. As the vehicle 12 passes over a trigger mechanism 122 (FIG. 19) of the second stunt track segment 114, a biasing spring (not shown) such as a torsion spring, is released and actuates the second portion 118 to pivot upwardly about an axis transverse to the travel direction along the track 14 as shown by the curved arrow line 124 (FIG. 23) and thereby “kick” the vehicle 12 into a forward somersault motion as shown by the curved arrow line 126 (FIG. 23). As shown in FIGS. 20 and 24, a third stunt track segment 128 has a first portion 130 and a second portion 132 pivotably connected thereto by a pin 134. As the vehicle 12 passes over a trigger mechanism 136 (FIG. 20) of the third stunt track segment 128, a biasing spring (not shown) such as a torsion spring, is released and actuates the second portion 132 to pivot upwardly about an axis transverse to the travel direction along the track 14 as shown by the curved arrow line 138 (FIG. 24) and thereby “kick” the vehicle 12 into a barrel roll motion as shown by the curved arrow line 140 (FIG. 24). In other embodiments, the stunt apparatus 110 may include additional or alternative stunt track segments for inducing different types of motions.
As used herein, “rotary indexer” refers to a device having a first part and a second part attached to the first part and rotatable relative to the first part to a plurality of pre-defined positions. As an example, FIGS. 25 and 26 show an embodiment of a rotary indexer 152 having a substantially cylindrical first part 152 that inserts into substantially tubular second part 154. The second part 154 defines slots (FIG. 25) that receive tabs angularly distributed on the surface of the first part 152 to fix rotation of the second part in a plurality of pre-defined orientations relative to the first part 152, including a first orientation shown in FIG. 25, and a second orientation shown in FIG. 26.
Referring to FIGS. 15 to 17, the plurality of stunt track segments are attached to the rotary indexer 142. The track 14 defines a travel direction for the toy vehicle 12 as shown by the directional arrow 144. The rotary indexer 142 permits the stunt track segments to be rotated, as shown by the curved directional arrow 146, about an axis that is substantially parallel to the travel direction, to selectively align each one of the stunt track segments individually with the track 14. That is, the track 14 and the aligned stunt track segment form a continuous travel path for the vehicle 12, even though there may be a small gap 50 between them. FIGS. 18, 19, and 20 show the rotary indexer 142 in first, second and third orientations, respectively, in which the first, second and third stunt track segments 112, 114, 128, respectively, are aligned with the track 14. FIG. 21 shows a knob 148 attached to the rotary indexer 142 to facilitate rotating the stunt track segments.
By virtue of the stunt track segments being rotatable about an axis that is substantially parallel to the travel direction defined by the track 14, the stunt apparatus 110 as a whole has a relatively compact configuration. This allows the stunt apparatus 110 to be placed within the confines of a part such as the stylized dinosaur head 26 with the stunt track 14 elements projecting outwardly in a tongue-like fashion, as shown in FIG. 1.
