Wide toy vehicle tracks which allow miniature toy vehicles to change lane positions have become very popular. Simple intersections can be provided for these wide tracks, but even greater entertainment would be provided if a deflector were available at the intersection which could be operated by a child to change a toy vehicle direction by 90 instead of allowing the vehicle to pass straight through the intersection. Such a deflector mechanism must be simple in order to permit sale at low cost, and yet is must provide smooth vehicleengaging surfaces at any position to which the deflector is operated in order to avoid upsetting the fast moving toy vehicles. The smooth surfaces which must be provided include a smooth side wall surface, particularly when the direction of the vehicle is being changed by 90, and a smooth horizontal surface where the vehicle is passing straight through the intersection.

SUMMARY OF THE INVENTION In accordance with one embodiment of the present invention, a deflector accessory of simple construction is provided which can be manually operated to permit toy vehicles to move straight through a track intersection or to deflect toy vehicles 90 at the intersection, without upsetting the toy vehicles even if they are moving at high speed. The accessory includes a frame with a crossover track surface that has an aperture in it, and a deflector member slideably mounted in the aperture for up and down movement therein. The deflector member can be moved between an upward position wherein it deflects toy vehicles 90 at the intersection, or to a downward position wherein the deflector is substantially flush with the crossover track surface to allow vehicles to move straight through the intersection. The deflector member is elongated and has concave surfaces on either side which define curves of approximately 90. The deflector member is tapered in width at each end portion so that there is considerable clearance with the walls of the frame aperture during most of the deflector travel. However, there is very little clearance between the deflector member and frame when the deflector member is in its raised position, so that the ends of the deflector surfaces are accurately maintained tangent with the outer walls of the tracks. A manual operating mechanism includes a lever pivotly mounted on the frame and having a button on one end which can be depressed by a child and having a portion contacting the middle of the deflector for lifting it when the button is depressed.

The novel features of the invention are set forth with particularity in the appended claims. The invention will best be understood from the following description when read in conjunction with the accompanying drawmgs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates a figure 8 track layout which includes two loops of

track

10, 12 and an intersection deflector accessory 14 positioned where the loop tracks are adjacent. The intersection accessory 14 has a frame 16 with a level crossover track surface 18, and has a deflector member 20 which can move up and down in an aperture formed in the track surface 18. When the'deflector member or deflector 20 is in its upward position, it lies above the crossover track surface 18, and serves to deflect a toy vehicle 22 by so that is diverted from onetrack end 24 to another track end 26 which extends 90 from the first track end, instead of allowing the vehicle to continue straight ahead through the intersection onto another track end 28 which extends from the original track end 24. When the deflector 20 is lowered, it moves down to a position flush with the crossover track surface 18, so that a toy vehicle can pass straight through the intersection instead of being diverted thereat. A child can operate the mechanism by depressing a button 30 to raise the deflector, and by releasing the button to allow the deflector to move down. When a child raises the deflector, he causes the toy vehicle to repeatedly traverse only one of the loops of the figure 8, while lowering of the deflector allows the vehicle to cross onto the other loop of the figure 8.

Referring also to the other Figures of the drawings, it can be seen that the deflector 20 is elongated and has a

concave deflector surface

32, 34 on either side. Each deflector surface extends in a curve of approximately 90 between its opposite ends, that is, the opposite ends are substantially perpendicular. The frame also has stationary side walls at 36-39 which extend tangent to the ends of the

deflector surfaces

32, 34 when the deflector is in its raised position. These fixed surfaces 36-39 are positioned to minimize discontinuities with the

deflector surfaces

32,34, so that there is a minimum of destabilization of toy vehicles.

The frame 16 of the accessory has four groups of connector tongues 41-44, each including three tongues for reception in the track ends to hold the track ends to the frame. Each track has a vehicle-supporting surface 46 and two

side walls

48,50 for confining toy vehicles. The frame has a pair of

tabs

52,54 for engaging the

side walls

48,50 of each track end to hold the side walls at a predetermined orientation. The tabs 52 defleet the side walls at the ends of the tracks to a more vertical position than they otherwise would assume, so the side walls are tangent with the walls 3639 on the frame. Accordingly, a minimum of discontinuity is present where the track side wall such as 48 meets a frame wall 36. The frame wall 36 is tangent to a corresponding end of a deflector surface 32. Such continuity is important at that side of the track end which is aligned with one of the deflector surfaces, because toy vehicles generally move along that side. Each of the looped

tracks

10, 12 is curved, and is much wider than the toy vehicles 22 which move along them. The toy vehicles generally have a tendency to move to the outside of the curve, and therefore tend to be moving along the side of the track which is smoothly merged to one end of the deflector member. The elimination of large discontinuities at the side of the vehicle path is important in order to prevent upsetting of the vehicle when it travels at high speed along the track layout.

The deflector member is mounted on the frame 16 so that it can slide up and down thereon. A lever 60 (FIG. 4) which has trunnions 62 pivotally mounted on the frame, moves the deflector 20 up and down. The button which can be depressed by a child, is located on one side of the trunnions 62 while an operating end portion 64 which contacts the deflector member is located on the other side of the trunnions. Thus, when a child depresses the button 30, the lever 60 pivots and the operating end portion 64 lifts the deflector membet, as from the position shown in FIG. 4 to the position shown in FIG. 3. When a child releases the button 30, the deflector members is released so that gravity can move it down to its lowermost position. When the deflector member is in its lowermost position its upper surface 20U is substantially flush with the crossover track surface 18. As a result, there is a minimum discontinuity in the surface 18 and therefore there is a minimum tendency to unstabilize toy vehicles moving rapidly straight through the intersection. The fact that the deflector member has concave surfaces on both sides means that it is wide near each end. Thus, unless its upper surface were substantially flush with the frame surface 18, toy vehicles could drop when moving over the top of the deflector member and would be unstabilized and could crash.

The operating end portion 64 of the lever contacts the deflector member 20 near the center thereof. As a result, there is a minimum tendency to tilt the deflector member when it is raised, and therefore there is a minimum tendency of the deflector to bind. When the deflector member 20 is released to drop down, it moves down until flanges 66 at its lower end rest on a floor that is supporting the frame 16. A level floor assures that the deflector member will not be tilted in any direction in its lowermost position, so that there will be a minimum tendency for it to bind when it is next moved up. A pair of

projections

68,70 is provided which can support the deflector member 20 if it should move slightly below its lowermost position, to prevent the deflector member from dropping out of the frame when the frame is not resting on the ground.

As mentioned above, it is important to maintain the ends of the concave deflector surfaces 32,34 in accurate alignment with the stationary upstanding frame walls such as 36,38 when the deflector member is in its upward, deflecting position. As illustrated in FIG. 6, the deflector member 20 is tapered in width, as measured between its

surfaces

32,34 near its ends. As a result, when the deflector member 20 is in its downward position, there is a considerable clearance between it and the walls of the hole 68 through which it moves, thereby reducing the tendency of binding during most of the up and down travel of the deflector member.

However, when the deflector member is in its raised position, there is very little clearance, if any, between the side walls which form the

surfaces

32,34 and the walls of the frame hole 68. This means that the deflector member is closely located with respect to the frame, so that the ends of the concave deflector surfaces 32,34 are maintained in accurate alignment with the stationary upstanding frame walls such as 36,38.

The connectors on the frame 16 are positioned so that the track ends which extend 180 from each other, such as the track ends 24,28 illustrated in FIG. 1, are not exactly aligned with one another, but instead are ofiset from one another. This offsetting is provided to minimize the possibility of crashing of a toy vehicle which moves straight through the intersection. Toy vehicles entering the intersection after having passed along the curved track, tend to ride near the outside wall of the track, as mentioned above. Thus, a toy vehicle moving along the track end 24 illustrated in FIG. 5, tends to assume a position near the track side 48. If the toy vehicle moves straight through the intersection onto the opposite track end 28, and if the opposite track end 28 were not offset from alignment with the track end 24, then there would be a possibility that the toy vehicle would hit the frame portion 71 which connects to the side wall 72 of the track end 28. This would be possible inasmuch as there is no guide rail or wall along the crossover track surface 18 that prevents wandering of a toy vehicle passing straight through the intersection. However, the track 28 is instead offset in the manner shown, so it extends along an imaginary line 73 that passes through the vehicle supporting surface 75 of the opposite track 28. As a result, a vehicle moving near the side wall 48 of one track, and that passes through the intersection, will enter the opposite track end 28 without hitting the frame portion 71 or track side wall 72 even if there is a slight wandering of the vehicle.

FIGS. 8 and 9 illustrate an intersection accessory constructed in accordance with another embodiment of the invention, which utilizes a deflector member 92 that can be rotated by manual rotation of a knob 94. In the position illustrated in solid lines in FIG. 8, the deflector member deflects toy vehicles between the track pairs 96,98 or between the track pairs 100,102. In the position of the deflector member indicated in phantom lines at 92a, the deflector member deflects toy vehicles between the track pairs 96,100 or between the track pairs 98,102. Where the track layout forms a figure 8, a child can confine a vehicle to one loop of the figure 8 or permit the vehicle to move to the other loop.

The deflector member 92 is mounted on a turntable 104 that can turn slightly more than 135 in a counterclockwise direction (as viewed from above) from the position shown in solid lines to the position at 92b. A child may turn the deflector member by 90 to the position 92a, or may turn it only 45 or as much as 135. In the 45 position at 92b or the 135 position at 920, the deflector member permits toy vehicles moving near one edge of a track to pass straight through the intersection without encountering the deflector member. Referring to FIG. 9, the turntable is fixed to an arm 106 that is rotatably mounted along axis 108. The arm is pivotally connected at 110 to one end of a link 112. The other end of the link is pivotally connected at 114 to an arm 116 that is fixed to the manually turnable knob 94. When a child turns the knob 94, the link 112 causes the arm 106 and turntable 194 to rotate. A pair of stops 118,120 prevent turntable rotation of more than about 135.

Thus, the invention provides a toy vehicle accessory of simple construction, which forms an intersection for a plurality of track ends, and which can be operated by a child to control the direction of a toy vehicle. In one accessory, the vehicle is controlled to either allow it to continue substantially along its initial direction of travel or to deflect it. The accessory includes a deflector or deflector member with concave deflector surfaces on either side, and which can move through an opening in a frame between a lowered position wherein it is flush with the crossover track surface of the frame and a raised position wherein it is above the crossover track surface for deflecting toy vehicles. Each concave deflector surface extends in a curve of approximately 90, so that toy vehicles are made to change direction by approximately 90. Of course, the intersections do not have to be at 90, and the deflector can be correspondingly formed. Each end of a deflector surface is positioned substantially tangent to a side wall of a track end which is connected to the frame, and the frame may include a stationary upstanding surface between the track side wall and the deflector. The deflector member is tapered in width near each end portion,'so that it can loosely slide on the frame until it is in its raised position, and so that the deflector member is closely located in its raised position to accurately maintain its ends tangent with the track side rails. Connector means on the frame which connect to the ends of tracks, hold the tracks so that the side rails thereof which are substantially tangent to the deflector member are not aligned with a corresponding side rail of the opposite track end, but are offset from it. This permits a toy vehicle to pass through the intersection onto the opposite track end without hitting a side wall thereof or of the frame even if there is slight wandering of the vehicle in moving across the intersection. In another deflector accessory, the deflector member is rotated between different positions at the intersection. An accessory can be provided that both rotates and raises and lowers a deflector member.
