Description
BACKGROUND OF THE INVENTION
This invention relates to toy vehicle track accessories.
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.degree. 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 vehicle-engaging 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.degree.,
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.degree. 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.degree. 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.degree.. 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 drawings.

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 90.degree. so that is diverted from one track end 24 to another
track end 26 which extends 90.degree. from the first track end,
instead of allowing the vehicle to continue straight ahead through
the intersection onto another track end 28 which extends
180.degree. 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.degree. 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 deflect 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 36-39 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 20 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 30 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 member, 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.degree. from each other, such as the track
ends 24,28 illustrated in FIG. 1, are not exactly aligned with one
another, but instead are offset 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 90 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.degree. 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.degree. to the position 92a, or may turn it only 45.degree. or
as much as 135.degree.. In the 45.degree. position at 92b or the
135.degree. position at 92c, 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 104 to rotate. A pair of stops
118,120 prevent turntable rotation of more than about
135.degree..
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.degree., so that toy vehicles are made to change direction by
approximately 90.degree.. Of course, the intersections do not have
to be at 90.degree., 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.
Although particular embodiments of the invention have been
described and illustrated herein, it is recognized that
modifications and variations may readily occur to those skilled in
the art and consequently it is intended that the claims be
interpreted to cover such modifications and equivalents.
