Various embodiments of the present invention are related to toys, and in particular, a track set on which toy vehicles may travel.
Toy vehicle track sets have been popular for many years and generally include one or more track sections arranged to form a path around which one or more toy vehicles can travel. Toy vehicles which may be used on such track sets may be either self-powered vehicles or may receive power from an external source.
Accordingly, it is desirable to provide toy track set with features that provide unique paths for the toy vehicles of the toy track to travel on.
In one embodiment, a track set is disclosed. The track set includes a track portion configured for receiving at least one device configured to traverse within the track portion, and a rotatable track portion. The rotatable track portion includes a receiving member and a generally spiral portion. The rotatable track portion is selectively rotatable about an axis. The receiving member is positioned to selectively receive the at least one device from the track portion as the rotatable track portion rotates. Movement of the device within the spiral portion generally maintains rotation of the rotatable track portion about the axis.
In another embodiment, a track set toy is disclosed. The track set includes a track portion configured for receiving at least one device configured to traverse within the track portion, a rotatable track portion, and a diverter member. The rotatable track portion includes a receiving member, a generally spiral portion, and an exit portion. The rotatable track portion is selectively rotatable about an axis. The receiving member is positioned to receive the device from the track portion. Movement of the device within the spiral portion generally maintains rotation of the rotatable track portion about the axis. The rotatable track portion terminates at the exit portion. The diverter track portion is positioned to receive the device from the exit portion of the rotatable track portion. The track portion is configured to allow the device to exit therefrom via the exit portion to another track portion.
Other features, advantages and details appear, by way of example only, in the following description of embodiments, the description referring to the drawings in which:
Referring now to
In the embodiments as shown in
The receiving track portion 20 may include various track segments configured for receiving at least one moveable device (shown in
The rotatable track segment 22 is rotatable about an axis A-A (shown in
The rotatable track segment 22 includes a receiving member 60, a generally spiral portion 62, and an exit portion 64. The receiving member 60 may include a scoop 61 that is configured to receive or scoop up one of the toy vehicles 50 from an end or end portion 63 of a feeding segment 66 (shown at least in
In the exemplary embodiment shown in
A support member 65 is configured to support end portion 63 and also allow scoop 61 to pass over the end portion 63 of the feeding portion 66 as the rotatable track segment 22 rotates in the counter clockwise direction. As mentioned above, when scoop 61 passes over the end 63 of feeding portion 66, a toy vehicle 50 located on the end portion 63 is scooped or shifted laterally and/or downwardly from the feeding portion 66 onto the rotatable track segment 22 or the spiral portion 62 via receiving member 60. Once received onto the spiral portion 62, the weight of the toy vehicle(s) 50 within or on the rotatable track segment 22 exert a reactive centrifugal force upon the rotatable track segment 22 or a force that causes rotational movement of the rotatable track segment 22 in the direction of arrow 54, via gravity acting upon the toy vehicle 50 as the toy vehicle(s) 50 traverse(s) within or on the rotatable track segment 22. The force or forces are partially created by movement of the toy vehicle(s) 50 within or on the rotatable track segment 22, and this movement generally sustains or promotes rotation of the rotatable track segment 22. Therefore, rotation of the rotatable track segment 22 is generally self-sustaining as long as there are available toy vehicles 50 queened up on the end portion 63 of the feeding portion 66 such that they can be scooped into the receiving portion 60 of the rotatable track segment 22 as the scoop 61 travels over the end portion 63. In other words, for every rotation of scoop 61 about axis A-A, a new toy vehicle 50 is introduced or scooped into the receiving portion 60 of the rotatable track segment 22, so long as the toy vehicle 50 is located at end portion 63 as the scoop 61 travels over it. In addition and as illustrated, end portion 63 is lower than the opposite end 69 of the feeding portion 66 of the receiving track portion 20 so that the toy vehicles 50 will roll towards end portion 63 and be scooped into receiving portion 60 of the spiral portion 62 as it rotates about axis A-A.
In various embodiments, the rotatable track segment 22 may be configured to allow for the toy vehicle(s) 50 to generally sustain or promote rotation of the rotatable track segment 22 in a specific (e.g., clockwise or counterclockwise) direction. This may accomplished, as seen in the exemplary embodiment, by configuring the rotatable track segment 22 with an increasing radius from its axis of rotation. This feature is readily apparent from the connectors 58 of increasing length that support the rotatable track segment 22 about the shaft 52. The weight of the wheeled toy vehicle 50 imparts a centrifugal force on the rotatable track segment 22 via gravity. In particular, the generally spiral portion 62 of the rotatable track segment 22 begins at the receiving member 60 and ends at end 64, and winds or revolves about a center axis (e.g., at the axis A-A or shaft 52 as seen in
As such and once the spiral portion 62 is imparted with an initial rotational movement, the spiral configuration of track segment 22 and the weight of the toy vehicle 50 causes the spiral portion 62 to continue to rotate in the same direction until the toy vehicle exits from end 64 of the track segment 22. As such, the spiral portion 62 may also be viewed as an elevator transferring a toy vehicle 50 vertically from the feeding segment 66 to the second track portion 70 located below the spiral portion 62. During this rotational movement of spiral portion 62 additional toy vehicles 50 may enter the track segment 22 via operation of the scoop 61 and receiving member 60 and in one embodiment multiple toy vehicles 50 may be received on the track segment 22 as it is rotating.
As mentioned above, the rotatable track segment 22 terminates at the exit portion 64. Referring specifically to
The toy vehicles 50 traverse within the linear segments 70 of the diverter track set 24 in the general direction D1. In the exemplary embodiment as shown in
The curved bridge 28 is movably mounted to the track set 10 so that it can receive toy vehicles 50 from an end portion 76 of the curved segment 74 of the diverter track set 24. The curved bridge 28 is configured for selectively pivoting or swinging in the direction of arrows 75 by movement of the toy vehicles 50 about the curved bridge 28 as they are received from the curved segment 74. The curved bridge 28 includes a generally curved or arcuate profile having a plurality of up and down features for the toy vehicles 50 to traverse within. In the illustrated embodiment, the curved bridge 28 has a curved profile to create a trough T, surrounded by raised portions 77. Of course, any other configuration having multiple troughs is contemplated to be within the scope of exemplary embodiments of the present invention. Also, although a trough T is illustrated, the curved bridge 28 may also be curved in an upwards direction as well, to create a raised portion.
Referring now to
Depending on the specific motion dynamics, the curved bridge 28 may swing such that the end portion 80 is positioned adjacent to the second diverter track segment 30 to receive one of the toy vehicles 50 (shown in
In a basic embodiment, the curved bridge 28 is connected to a member 90. The member 90 is attached to the remainder of the system via a pivot point at one end of the member 90. Thus, the curved bridge 28 and the member 90 rotate about the fixed pivot point. In some embodiments, the curved bridge 28 is attached to the member 90 at a point that is offset from the center of the length of the curved bridge 28. For example, the curved bridge 28 may be attached to the member 90 at a point offset from the bottom of the trough T. The offset adds complexity to the rotation of the curved bridge 28 about the fixed pivot point. Additional complexity to the motion occurs with the introduction of motion from a moving toy vehicle 50 traversing the curved bridge 28.
In an intermediate embodiment, the member 90 extends beyond the curved bridge. Additional weight may be attached to the member 90. In some embodiments, the member 90 has one or more appendages upon which the additional weight may be attached. Thus, the additional weight may be attached offset from a main line of the member 90. For example, an end member 92 is illustrated as attached to an appendage and offset from the main line of the member 90.
In a complex embodiment, the additional weight is in the form of a free-swinging pendulum 82. As illustrated, the swinging pendulum 82 includes a plurality of baskets 84 that are configured for receiving a mass, such as one or more of the toy vehicles 50. The specific motion of the curved bridge 28 (e.g., the swinging of the curved bridge 28) may depend on at least the movement of the toy vehicles 50 along the curved bridge 28, the number of toy vehicles 50 presently located on the curved bridge 28, the free-swinging pendulum 82 that is attached to the curved bridge 28, and their respective points of attachment/pivot with respect to each other. The presence of a mass in either or both the baskets 84 also affects the dynamics of the curved bridge 28.
The second diverter track segment 30 may be attached to the drawbridge track segment 32, and directs the toy vehicles 50 towards the drawbridge track segment 32. The drawbridge track segment 32 includes a normally raised bridge portion R. However, turning now to
