Abstract
A toy object and slot track system includes a plurality of track segments each having a retaining slot provided thereon and defining a slotted track surface. The track segments include straight, curved and twisted track segments connectable to form straight and curved tracks with slotted track surfaces facing upwards and/or downwards and twisted tracks, and concave/convex track segments connectable to form loop-shaped tracks with concave/convex slotted track surfaces facing inwards and/or outwards. The system includes at least one toy object having first and second protruding pins for slidable engagement along the retaining slot. At least one of the first and second protruding pins has a free end portion retainable within the retaining slot such that the toy object can move along the tracks without falling off under gravitational pulling force.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/715,570 filed Sep. 12, 2005 and U.S. Provisional Patent Application No. 60/750,337 filed Dec. 15, 2005, which are hereby incorporated by reference in their entirety.
- The present invention generally relates to a game and, in particular, to a toy object and slot track system including a plurality of track segments with slotted track surfaces facing different directions whereby toy objects, such as slot cars, are adapted to move along the track in different orientations relative to the floor without falling off the track.
- Slot cars are electric toy cars that fit into a slot track and are controlled by the players through hand-held controllers. The slot track is assembled from a number of track segments each having one or more guide slots for receiving a guide pin extending from the underside of each slot car and guiding each slot car along the track. The slot cars are powered through a pair of electric conductors provided on the track. The slot track is usually designed to be assembled and laid on the floor such that the slot cars run along the slot track in a generally upright position.
- U.S. Pat. No. 5,342,048 discloses a wall-mounting slot track system. The slot track system includes a plurality of substrates vertically hung on a wall. A slot track extends across each substrate to form a continuous path perpendicular to the floor. Slot cars are retained on the slot track by guide pins extending from the underside of the slot cars.
- However, this wall-mounting slot track system lacks versatility and play value. Even though different wall-mount slot track systems could be connected to form a bigger layout, the track segments of the wall-mounting slot track system are basically fixed on a number of substrates and the layout itself could not be defined by players. The players are not able to design and assemble their own unique and favorite racing tracks before each racing game.
- The track segments of this type of wall-mounting slot track system are mounted on vertical substrates in such a manner that the track segments are all vertically oriented with slotted track surfaces facing only in one direction, i.e. away from the wall.
- Since the slot cars are constantly kept in a sideway position, the guide pins of the slot cars as well as the slots of the track are subject to damages due to friction and action of the slot cars.
- The above description of the background is provided to aid in understanding the invention, but is not admitted to describe or constitute pertinent prior art to the invention, or consider the cited document as material to the patentability of the claims of the present application.

The plurality of track segments includes straight and curved track segments connectable to form straight and curved tracks with slotted track surfaces facing upwards and/or downwards, and concave/convex track segments connectable to form at least one loop-shaped track with concave/convex slotted track surfaces facing inwards and/or outwards. The system may optionally include one toy object having first and second protruding pins receivable in and slidable along the retaining slot. At least one of the first and second protruding pins of the optional toy object has a free end portion retainable within the retaining slot.
- The track segments can be connectable to form tracks including but are not limited to spiral tracks, barrel-shaped tracks, figure-8 shaped tracks, upwardly inclining U-shaped tracks, and route-reversing loop tracks.
- The plurality of track segments may further include route diverging/converging track segments, twisted track segments, and track segments arranged in a back-to-back relationship with slotted track surfaces facing opposite directions.
- In an embodiment, each track segment has two retaining slots provided on one surface thereof. In another embodiment, each track segment has at least one continuous retaining slot provided on one surface thereof, and at least one continuous retaining slot provided on the other surface thereof opposite to the one surface.
- In one embodiment, the first and second protruding pins extend from an underside of the toy object. In another embodiment, the first and second protruding pins extend from the lateral sides of the toy object respectively.
- In an embodiment, each of the first and second protruding pins has a free end portion retainable within the retaining slot.
- In one embodiment, the retaining slot and the free end portion are generally T-shaped.
- The toy object further includes a motor and a magnet operatively coupled to a pair of conductive rails extending along the retaining slot.
- According to another aspect of the present invention, there is provided a toy object and route-reversing track system including (a) a first track segment having a first retaining slot provided on an upper surface thereof and a second retaining slot provided on a lower surface thereof, (b) a second track segment having a third retaining slot provided on a concave surface thereof, the second track segment being pivotable between a first position where one end of the third retaining slot is in registration with the first retaining slot and a second position where the other end of the third retaining slot is in registration with the second retaining slot; and (c) a toy object having first and second protruding pins receivable in and slidable along the first, second, and third retaining slots, at least one of the first and second protruding pins having a free end portion retainable within the first, second, and third retaining slots.
- The system further includes a weight for biasing the second pivotable track segment in the first position. In an embodiment, the weight takes the form of a container containing a plurality of objects adapted for weight adjustment.
- The system further includes a funnel-shaped slot provided at the one end of the third retaining slot, a pair of electrical contacts provided at the other end of the third retaining slot, and a pair of conductive rails electrically coupled to the pair of electrical contacts and extending along the third retaining slot except for the funnel-shaped slot, wherein the pair of electrical contacts is electrically coupled to a pair of conductive rails provided along the first retaining slot when the second track segment is in the second position.
- Although the invention is shown and described with respect to certain embodiments, it is obvious that equivalents and modifications will occur to others skilled in the art upon the reading and understanding of the specification. The present invention includes all such equivalents and modifications, and is limited only by the scope of the claims.
