TOY VEHICLE WITH ADJUSTABLE MASS THAT CHANGES DRIVING CHARACTERISTICS
In an aspect, a toy vehicle is provided and includes a main body, wheels and a power source. The main body includes a fixed portion and a movable portion that is movably connected to the fixed position for movement between a first movable portion position and a second movable portion position, which moves the center of gravity of the vehicle to a first or second position respectively. When the movable portion is in the first position, the power source drives the toy vehicle into a wheelie. When the movable portion is in the second position, the power source drives the toy vehicle without driving the toy vehicle into a wheelie.
The specification relates generally to toy vehicles and more particularly to a toy vehicle such as a motorcycle, that can perform different types of maneuver.
BACKGROUND OF THE DISCLOSUREThere is a market desire for toy vehicles that can perform different types of maneuver in order to keep the user entertained. However, there are also conflicting market forces, such as a need to keep costs low for such products. Some toy vehicles that are capable of carrying out different maneuvers include the Upriser™ motorcycle by Spin Master Ltd. However, such a device can be expensive for some users, and requires time to learn how to use, and may therefore be less appropriate for use by some users. There is therefore a need for toy vehicles that can perform different types of maneuver to keep a user entertained and engaged, while remaining relatively low cost, and easy to use.
SUMMARY OF THE DISCLOSUREIn an aspect, a toy vehicle is provided and includes a main body, a plurality of wheels and a power source. The main body includes a fixed portion and a movable portion that is movably connected to the fixed position for movement between a first movable portion position and a second movable portion position. The plurality of wheels are rotatably mounted to the main body and positioned for rollably supporting the main body on a support surface. The plurality of wheels includes at least one driven wheel. The power source is supported by the main body and is operable to store energy therein, and is operatively connected to the at least one driven wheel so as to release stored energy to drive rotation of the at least one driven wheel, so as to drive the toy vehicle on the support surface. Positioning of the movable portion of the main body in the first movable portion position moves a center of gravity of the toy vehicle to a first CG position, and positioning of the movable portion of the main body in the second movable portion position moves the center of gravity of the toy vehicle to a second CG position. The movable portion is stable in the first movable portion position and in the second movable portion position. Wherein the movable portion of the main body is in the first movable portion position, release of the stored energy drives the toy vehicle into a wheelie while driving the toy vehicle on the support surface. When the movable portion of the main body is in the second movable portion position, release of the stored energy drives the toy vehicle on the support surface without driving the toy vehicle into a wheelie.

Reference is made to
The main body 12 includes a fixed portion 22 and a movable portion 24 that is movably connected to the fixed position for movement between a first movable portion position shown in
The plurality of wheels 14 are rotatably mounted to the main body, and are positioned for rollably supporting the main body 12 on a support surface G. The plurality of wheels 14 includes at least one driven wheel 26. In the embodiment shown, as noted above, the toy vehicle 10 is in the form of a toy motorcycle and the plurality of wheels 14 includes exactly one front wheel 14a and exactly one rear wheel 14b. In the embodiment shown, the at least one driven wheel 26 includes the rear wheel 14b. More specifically, in the embodiment shown, the at least one driven wheel 26 is the rear wheel 14b.
The power source 16 is supported by the main body 12 and is operable to store energy therein. In the embodiment shown, the power source includes a flywheel 28 (
To charge the flywheel 28, the user may swipe the toy vehicle 10 along the support surface G one or more times to build up kinetic energy in the flywheel 28. At this point the user is holding the toy vehicle 10 and the flywheel 28 is releasing its stored kinetic energy to drive rotation of the rear wheel 14b. The user can release the toy vehicle 10 on the support surface G, at which point the rotation of the flywheel 28 will drive continued rotation of the rear wheel 14b until the kinetic energy in the flywheel 28 is consumed via friction (e.g. between the flywheel 28 and the main body 12, which rotatably supports the flywheel 28).
A role of the movable portion 24 of the main body 12 is described further below. Positioning of the movable portion 24 of the main body 12 in the first movable portion position moves a center of gravity CofG of the toy vehicle 10 to a first CG position as shown in
When the movable portion 24 of the main body 12 is in the first movable portion position, the position of the center of gravity CofG is such that, release of the stored energy of the power source 16 (e.g. when the user releases the toy vehicle 10 with the spinning flywheel 28 (and therefore spinning rear wheel 14b) on the support surface G), drives the toy vehicle 10 into a wheelie (as shown in
When the movable portion 24 of the main body 12 is in the second movable portion position, release of the stored energy by the power source 16 drives the toy vehicle 10 on the support surface G without driving the toy vehicle into a wheelie 12. In other words, the center of gravity CofG is positioned sufficiently forwardly on the toy vehicle 10 when the movable portion 24 of the main body 12 is in the second movable portion position, that the acceleration of the toy vehicle 10 that occurs when the user places the toy vehicle 10 on the support surface G is below the amount needed to cause the toy vehicle 10 to lift up into a wheelie. In the embodiment shown, the toy vehicle 10 may drive along the support surface G for a period of time, as shown in
Optionally, if the toy vehicle 10 tips over while driving along the support surface G when the movable portion 24 of the main body 12 is in the second movable portion position, the toy vehicle 10 is configured to keep its at least one driven wheel 26 in contact with the support surface G, so that the at least one driven wheel 26 can continue to drive the toy vehicle 10 on the support surface G, as shown in
In the embodiment shown, the fulcrum feature 44 may be the knee of the motorcycle rider.
As a result of the engagement of the at least one driven wheel 24 with the support surface G, the toy vehicle 10 may be driven in a generally circular pattern on the support surface G as a result of the position of the point at which the rear wheel 14b contacts the support surface G relative to the center of gravity CofG.
This movement in a generally circular pattern on the support surface G may be referred to as a ‘burnout’ maneuver. Thus, the toy vehicle 10 may be configured to perform a first maneuver (namely, a wheelie, as described above) when the movable portion 24 is in the first movable portion position and may be configured to perform a second maneuver (the burnout maneuver), when the movable portion 24 is in the second movable portion position. It will be noted that the second maneuver could also be considered driving of the toy vehicle 10 on the support surface G while the toy vehicle 10 is upright (e.g. in the position as shown in
It will be noted, that, if the toy vehicle 10 tips over onto its first side 46 while the movable portion 24 is in the first movable portion position, the toy vehicle 10 will also be held with the at least one driven wheel 26 in contact with the support surface G based on the relative longitudinal position of the fulcrum feature 44 relative to the first CG position of the center of gravity CofG so as to hold the toy vehicle 10 with the at least one driven wheel 26 in contact with the support surface G, resulting in driving the toy vehicle 10 in a circular pattern (i.e. the burnout maneuver) in similar manner to how the toy vehicle 10 is driven when tipped over when the movable portion 24 is in the second movable portion position, described above.
The fulcrum feature 44 may be a first fulcrum feature 44, and the main body 12 may further include a second fulcrum feature 56 that extends laterally on a second side 58 of the main body 12. The fulcrum feature 44 is positioned at a second selected longitudinal position relative to the second CG position of the center of gravity CofG so as to hold the toy vehicle 10 with the at least one driven wheel 26 in contact with the support surface G, as described above in relation to the first fulcrum feature 44, such that, when the movable portion 24 of the main body 12 is in the second movable portion position and the toy vehicle 10 is tipped over onto the second side 58 of the main body 12, the contact by the at least one driven wheel 24 with the support surface G drives the toy vehicle 10 on the support surface G while tipped over, in a circular pattern.
The movable portion 24 may be stable in both the first movable portion position. and in the second movable portion position. To this end, a detent mechanism 48 may be provided between the movable portion 24 and the fixed portion 22. In the embodiment shown the fixed portion 22 may include a plurality of detents shown at 50 and 52 (
While the entire fixed portion 22 of the main body may be actually fixed in place, it is alternatively possible that some movement may be permitted, while not affecting the position of the center of gravity CofG of the toy vehicle 10 sufficiently to permit two different maneuvers to be performed. For example, the front wheel 14a of the toy vehicle 10 may be mounted on a fork member 60 that is permitted to pivot a bit relative to the rest of the toy vehicle 10. This pivoting movement of the front wheel 14a may facilitate tipping of the toy vehicle 10 onto one of its first and second sides 46 and 58 in order to cause it to operate the burnout maneuver. As noted above, since the different possible positions of the fork member 60 throughout its pivoting range of movement do not move the center of gravity CofG of the toy vehicle sufficiently to permit or prevent the toy vehicle 10 from entering into a particular maneuver, for the purposes described herein the fork member 60 is still considered to be part of the fixed portion 22 of the main body 12. More specifically, it will be noted that, in all positions of the fork member in the range of movement when the movable portion of the main body is in the first movable portion position, release of the stored energy drives the toy vehicle into a wheelie while driving the toy vehicle on the support surface. The range of movement of the fork member 60 is shown at Ap in
Persons skilled in the art will appreciate that there are yet more alternative implementations and modifications possible, and that the above examples are only illustrations of one or more implementations. The scope, therefore, is only to be limited by the claims appended hereto and any amendments made thereto.
