Description
The present invention relates generally to toys, and in particular,
to a starting and finishing gate for use in a racing game wherein
self-powered cars travel about a racing course having first and
second racing lanes.
In copending application Ser. No. 868,449, filed Oct. 22, 1969,
entitled "Vehicle Racing Games," which application is assigned to
the assignee of the present application, there is disclosed a
racing game which is to be played with at least two vehicles which
are driven at substantially the same speed yet may be raced along
the raceway or track in different elapsed times, depending upon the
manipulative skills of the player of the game. In such racing game,
a car is assigned to each of the players, with each player having
the facility to switch his own car, as well as that of his opponent
from a racing course of longer length to a racing course of shorter
length, and vice versa, with a view to causing his own vehicle to
traverse the particular course in a shorter elapsed time and to
cause his opponent's vehicle to traverse the course in a
comparatively longer elapsed time. In a typical illustrative
embodiment, there is provided an interchangeable track assembly
which includes plural individual track sections which are
interconnectable into various track layouts to define the raceway
including an inside lane and an outside lane. The raceway includes
at least two track sections which include lane switching means
individually operable to switch the cars or vehicles from one lane
to the other. Respective switch-actuating means are operatively
connected to the lane-switching means for manipulation thereof
whereby the cars may be switched from one lane to the other and
back. A manual control is provided for each lane switching means
whereby each of the players may switch either his vehicle or that
of his opponent from one lane to the other, with the objective of
causing his vehicle to complete one or more laps about the raceway
in a shorter elapsed time than his opponent's vehicle.
In the use of this type of racing game, and indeed in almost any
racing game, it would be highly desirable to provide an
operator-controlled starting gate which would enable the two or
more cars to be simultaneously released to travel the racing course
and to also provide a finishing gate wherein a clear cut signal is
provided along one of the racing lanes to indicate which of the
cars has won the race. In the particular racing game of the
copending application, wherein both cars may be on one or the other
of the racing lanes as they approach the finishing line, it is
highly desirable to provide a gating arrangement wherein the cars
are directed onto the separate racing lanes as they approach the
finish line to avoid a collision between cars on the same lane.
Preferably, these related functions should be achieved by a device
which is inherently of simple and rugged construction such that it
may be manufactured on a mass production basis at relatively low
unit cost and utilized over long periods of time without
malfunctioning.
Broadly, it is an object of the present invention to provide a
starting and finishing gate for an automotive racing game which
provides for the start in unison of racing cars and provides a
visible signal of the winner at the end of any given race.
Specifically, it is within the contemplation of the present
invention to provide a starting and finishing gate useful in a
racing game wherein cars move between two lanes yet are separated
in advance of the finish line such that the winner of the race may
be indicated and the cars stopped without causing the cars to
interfere with each other.
It is a further object of the invention to provide a starting and
finishing gate for use in a racing game which is of simple and
rugged construction and is capable of manufacture on a mass
production basis at relatively low unit cost.
In accordance with an illustrative embodiment demonstrating objects
and features of the present invention, there is provided a starting
and finishing gate for use in a racing game, including a racing
course having first and second racing lanes which comprises a track
body including first and second lane sections forming parts of the
first and second racing lanes and adapted to be travelled by first
and second cars. First and second gate members are movably mounted
on the track body in operative relation to the first and second
lane sections respectively, and are mounted on the track body in
operative relation to the first and second lane sections for
movement from lane-blocking positions to lane-clearing positions.
The gate members establish a starting line for the cars when in the
lane blocking positions and free the cars to travel about the
racing course when in the lane clearing positions. Control means
are provided for moving the first and second gate members in unison
to release the cars at the commencement of a race. A finish
indicator is provided having respective first and second signalling
devices for indicating the arrival at a finishing line of one of
the cars in advance of the other. First and second car sensors are
mounted on the track body in operative relation to the first and
second lane sections, respectively, and are independently movable
in response to passage of cars along the corresponding one of the
first and second lane sections to provide first and second
actuating motions which are coupled to the finish indicator to
actuate one or the other of said first and second signalling
devices.
As a feature of the invention, the first and second sensors are
movable between operative and inoperative positions but are
disposed in their operative positions when the gate members are in
their lane blocking positions. Means are provided which are
operable in response to movement of the gate members to the lane
clearing positions for moving the first and second sensors into the
inoperative positions and for restoring the first and second
sensors to the operative position when the first and second gate
members are returned to the lane-blocking positions. Thus, when the
gate members are in their withdrawn or retracted position, the race
will continue without tripping the finish indicator,
notwithstanding the fact that the first and second sensors are
operated. When the gate members are brought to the lane-blocking
positions wherein they will stop cars at the finish of a race (and
also establish a starting position for the next race), the first
and second car sensors are enabled to achieve the desired function
of providing a signal as to which car has won the race.
As a further feature of the invention, provision is made in advance
of the finish indicator along the first and second racing lanes to
assure that the cars, whether on separate finishing lanes or on the
same finishing lane, will be separated from each other to pass onto
individual lanes as they approach the first and second car sensors
to signal the finish of the race without interfering with each
other and to also properly position the cars for the running of the
next race.
The above brief description, as well as further objects, features
and advantages of the present invention, will be more fully
appreciated by reference to the following detailed description of a
presently preferred, but nonetheless illustrative embodiment in
accordance with the present invention, when taken in conjunction
with the accompanying drawings, wherein:
FIG. 1 is a plan view of a typical track assembly defining one
specific raceway layout having inside and outside lanes and
incorporating a starting and finishing gate embodying features of
the present invention;
FIG. 2 is a top plan view of the starting and finishing gate;
FIG. 3 is a bottom plan view of the starting and finishing
gate;
FIG. 4 is a longitudinal elevational view, with parts broken away
and in section, of the starting and finishing gate;
FIG. 5 is a sectional view on an enlarged scale taken substantially
along the line 5--5 of FIG. 2, looking in the direction of the
arrows and showing the signal flags housed within the finish
indicator; and,
FIG. 6 is a partial sectional view taken substantially along the
lines 6--6 of FIG. 2, looking in the direction of the arrows and
showing one signal flag in its dropped position indicating the
finish and winner of a race.
Referring now to the drawings, there is shown a typical, but purely
illustrative, track layout for a racing game, generally designated
by the reference numeral 10, in which a starting and finishing
gate, generally designated by the reference numeral 12, in
accordance with the present invention, finds useful application.
The racing game includes a racing course having a first or inner
racing lane L.sub.1 and a second or outer racing lane L.sub.2. The
track sections which make up the inner and outer racing lanes or
courses L.sub.1, L.sub.2 are of varying lengths, shapes and
functions but have slots or grooves which make up the continuous
guideways of the inner and outer lanes of the raceway which
guideways receive depending guide pins on the cars (see FIG.
5).
In the typical but illustrative track layout, there are provided
straight track sections such as indicated at 14 which are
substantially rectangular and define straight runs of the raceway,
curved track sections such as indicated at 16 which make up the
curves of the raceway, fixed dual lane crossover sections such as
indicated at 18, 18', lane switching sections such as indicated at
20, 20', plural single lane sections of various sections, lengths
and configurations such as those designated at 22, 22' defining
continuations of the inner course or lane L.sub.1 and following the
respective lane switching sections 20, 20' and further plural
single lane sections of various lengths, shapes and configurations
such as those designated at 24, 24' defining corresponding runs of
the outer lane or course L.sub.2 and likewise following the
lane-switching sections 20, 20'.
Typical vehicles or cars for use in the present racing game are
shown along lanes L.sub.1, L.sub.2 and have been designated as A',
B'. These vehicles include a wheeled chassis containing a
fractional horsepower motor which is operated by one or more
batteries, such as of "N" size, and interchangeable car bodies to
impart different appearances thereto. For a complete description of
the construction of typical cars useful in accordance with the
present invention, reference may be made to U.S. Pat. No.
3,350,813, entitled "Electrically Powered Wheeled Toy Vehicle,"
which patent is assigned to the assignee of the present
invention.
At the operator-controlled stations A, B, there are provided hand
controls 26, 26' which enable the players to manipulate the lane
switching track sections 20, 20' as more fully described in
copending application Ser. No. 868,449 which is incorporated herein
by reference. It will suffice to understand for the present
purposes that the substantially constant speed vehicles A', B' will
make one or more laps about the racing course, being switched from
lane to lane under control of the players at control stations A, B,
with the cars starting from starting line S at the start-finish
gate track section 12. When the lead car enters the last lap and
the trailing car passes gate 12 (in the direction indicated by the
directional arrow in FIG. 1), the gate 12 is rendered operative and
becomes effective to automatically separate the cars as they
complete the last lap (if both are in the same lane), provides a
visible indication of the winner of the race at the finish line F,
and then stops the cars in their separate lanes at the starting
line S for the next race.
Reference will now be made to FIGS. 2 to 6, inclusive, for a
complete description of the starting and finishing gate of track
section 12 which may be employed in the illustrative racing game 10
which has been described in conjunction with FIG. 1. Gate 12
includes an elongated substantially rectangular track body 30
having an upper wall 32 and depending side flanges 34, 36. The
track body, which may be a plastic molded piece, is provided at its
opposite ends with connecting means, generally designated by the
reference 38, to enable the starting and finishing gate 12 to be
connected in various track layouts, as exemplified by the raceway
shown in FIG. 1. In its upper wall 32, track body 30 is formed with
first and second lane sections, grooves or guides 40, 42 which
provide continuous runs of the inner and outer lanes L.sub.1,
L.sub.2. Lane section 40 includes an entry end 40a and an exit end
40b. Similarly, lane section 42 includes an entry end 42a and an
exit end 42b. Track body 30 is also formed in upper wall 32 with
crossover grooves or guide lanes 44, 46. Crossover groove or guide
lane 44 has an entry end which emerges into the entry end 40a of
the first or inner lane section 40 and an exit end which merges
into the second or outer lane section 42 at an intermediate
location. Similarly, and in opposite fashion, crossover groove or
guide lane 46 has its entry end merging into the entry end 42a of
lane section 42 and its exit end merging into lane section 40 at an
intermediate location. The function of the crossover grooves 44, 46
in sorting out the cars at the finish of a race will be
subsequently described.
Extending along one side of each of the lane sections 40, 42
contiguous to their exit ends 40b, 42b, are longitudinally
extending fixed gate members 48, 50 which may be integrally molded
on the upper wall 32 of track body 30. Opposite the stationary
first and second gate members 48, 50 are first and second movable
gate members 52, 54 which are disposed in operative relation to the
first and second lane sections 40, 42 and are movable from
lane-blocking positions (illustrated by the full lines in FIG. 2)
to lane-clearing positions (illustrated by the dotted lines in FIG.
2). Gate members 52, 54 are mounted at pivots 56, 58 on upper wall
32 to one side of the lanes 40, 42. Upper wall 32 is provided with
rectangular cutouts 32a, 32b to enable actuating arms 60, 62 which
are integral with the gate members 52, 54 to project to the
underside of track body 30, as seen in FIG. 3.
Disposed at the underside of the track body 30 is a manually
operable control member 64 for actuation of gate members 52, 54 in
unison. Control member 64 includes a control lever 64a projecting
through cutout 36a in side flange 36. Control member 64 is medially
pivoted at 66 on the underside of track body 30 and is provided
with curved slots 64b, 64c which receive actuating pins 60a, 62a
depending from actuating arms 60, 62. Slots 64b, 64c are
dimensioned and positioned in relation to the actuating pins 60a,
62a such that when control lever 64a is in the position illustrated
in FIGS. 2 and 3, the gate members 52, 54 are in the illustrated
lane-blocking positions and when the control lever 64a is moved
toward the starting line S, movable gate members 52, 54 swing
outwardly into the lane-clearing positions (shown by the dotted
lines in FIG. 2) wherein they are substantially parallel to
stationary lane members 48, 50 and are out of obstructing relation
to lane sections 40, 42. Thus, a car, such as generally designated
at C in FIGS. 4 and 5 and having a depending guide pin P, is free
to commence its traverse about the raceway 10, for example as shown
in FIG. 1.
Mounted on the track body 30 forwardly of the finish line F is a
finish indicator, generally designated by the reference numeral 68,
which includes a standard 70 removably mounted on opposed mounting
blocks 72, 74 which define a vertically extending guideway into
which standard 70 may be plugged by the user. Standard 70 carries a
downwardly opening signal housing 76 which includes spaced front
and rear walls 76a, 76b. Disposed between the front and rear walls
76a, 76b is a rockable signalling device 78 which includes first
and second signals in the form of checkered flags 78a, 78b.
Signalling device 78 is pivotally mounted intermediate flags 78a,
78b at a fore-and-aft pivot 80 which is loosely mounted within an
elongated vertically extending slot 82 formed in standard 70.
Supporting shoulders 84, 86 are formed on the signalling device 78
at opposite sides of pivot 80 which shoulders normally rest upon
the upper ends of corresponding coupling or actuating members 88,
90 which are pivotally mounted on standard 70 at laterally
extending pivots 92, 94. Actuating members 88, 90 are weight
balanced to bear against respective stops 96, 98 formed on standard
70. For example, as seen in FIG. 4, actuating member 90 includes an
enlarged head 90a below pivot 94 which urges upstanding holding
finger 90b of actuating member 90 to a position wherein it
underlies shoulder 86. Similarly, the opposite coupling or
actuating member 88 bears beneath shoulder 84. Together, members
88, 90 hold signal flag in its balanced and hidden position, as
illustrated in FIG. 5. When, for example, holding finger 90 swings
in the clockwise direction in FIG. 4, as by actuating depending
finger 90c at the lower end of member 90, the corresponding support
for the signal device 78 is removed and it will drop in that
direction. In FIG. 6, the signal device is shown dropped into a
position corresponding to actuation of the coupling member 88.
The actuating or coupling members 88, 90 are selectively
manipulated to drop the appropriate one of the signal flags 78a,
78b through the provision of first and second car sensors 100, 102
which are mounted on the track body 30 in operative relation to the
first and second lane sections 40, 42, respectively, and are
independently movable in response to passage of cars along the
corresponding one of the first and second lane sections to provide
first and second actuating motions for the finish indicator or
signalling means 68. Sensors 100, 102 are mounted on a movable
slide plate or carrier 104 at pivots 106, 108 such that the car
sensors 100, 102 may be moved into and out of operative relation to
the depending fingers 88c, 90c on actuating or coupling members 88,
90. Specifically, slide plate or carrier 104 is provided with
elongated guide slots 104a, 104b, with guide slot 104a receiving
guide pin 110 mounted on or formed integrally with track body 30
and guide slot 104b receiving pivot pin 66. Thus, slide plate or
carrier 104 is mounted for limited longitudinal movement relative
to track body 30 as determined by the length of guide slots 104a,
104b. Normally, slide plate 104 is in the position illustrated in
FIG. 3 wherein the sensors 100, 102 are in a position to impart
actuating motion to depending fingers 88c, 90c. This position of
the slide plate 104 corresponds to the starting gate being closed
and with the movable gate members 52, 54 in their respective lane
blocking positions. Control member 64 is provided with an
upstanding pin 64d which is received within a cutout 104c in slide
plate 104 such that as the control lever 64a is moved to its
position to open gate members 52, 54 (the dotted line position in
FIG. 3), the slide plate 104 is longitudinally displaced to bring
the car sensors 100, 102 out of operative relation to the actuating
or coupling members 88, 90. In this clearance position, although
sensors 100, 102 are moved by the pins P of cars C traversing the
lane sections 40, 42, such actuating movement will not be imparted
to the actuating or coupling members 88, 90. However, when control
lever 64a is returned to the illustrated position, once again
closing gate members 52, 54, car sensors 100, 102 are once again
rendered effective in relation to actuating members 88, 90 to
signal the end of the race. Specifically, car sensors 100, 102
include sensing parts 100a, 102a, actuating parts 100b, 102b and
positioning arms 100c, 102c which are interconnected by spring 112
and bear against appropriate stops to position the sensing parts
100a, 102a to straddle the respective lane sections 40, 42. In this
normal position, the actuating parts 100b, 102b bear against the
depending fingers 88c, 90c of coupling members 88, 90 which extend
through appropriate cutouts formed in the top wall 32 of track body
30. When a car pivots its sensor about its pivot (i.e., sensor 100
moving around pivot 106), the actuating part will contact the
corresponding depending finger to manipulate the associated
coupling member and initiate the operation of the signalling device
in the appropriate direction. Although the sensors are in positions
to be actuated by the car pins when the gate is opened (the dotted
line position for control member 64 in FIG. 3), the actuating
motion imparted thereto is ineffective since the sensors are
sufficiently removed from the coupling members 88, 90 such that
pivoting of the sensors imparts no motion to the coupling members
88, 90.
Lane sorting is achieved by the provision of lane-switching members
114, 116 at the entry ends 40a, 42a of lane sections 40, 42 and
along the crossover grooves 44, 46. Lane-switching members 114, 116
are pivoted at 118, 120 and include outer sides 114a, 116a each of
which will serve as one side of the corresponding lane section
(i.e., straight side 116a serving as a part of lane section 42) and
curved inner sides 114b, 116b each of which will serve as one side
of the crossover grooves 44, 46 (i.e., curved side 116b forming
part of crossover groove 46). Additionally, lane-switching members
114, 116 include actuating projections 114c, 116c along their outer
sides which lie along the respective lane sections 40, 42 such that
the passage of cars along the corresponding lane sections will
automatically switch the positions of the lane-switching members.
The curved inner sides 114b, 116b perform the same function. For
example, lane-switching member 116 is in a position wherein a car
will pass along lane section 42. However, when the pin P of a car
passes projection 116c, lane-switching member 116 is swung to a
position wherein the next car will be diverted to travel along
crossover lane 46. Similarly, lane-switching member 114 is in a
position wherein the next car passing therealong will travel along
crossover groove 44 and as it does, the inner curved side 114b is
contacted and moves lane-switching member 114 to a position wherein
the next car will pass directly along lane section 40. It will be
appreciated that the lane-switching members 114, 116 are operated
independently of each other and assume either of the two
illustrated positions depending upon the passage of cars along lane
sections 40, 42. However, when the end of the race is to be
indicated, it is essential that both lane-switching members 114,
116 occupy the same relative position (i.e., both being arranged to
allow cars to pass along lane sections 40, 42, respectively and not
be crossed over). To this end, lane-switching members 114, 116 are
provided with depending cam followers 114d, 116d which project
through corresponding arcuate slots in upper wall 32 and are
positioned to be actuated by a common camming member 122 formed on
slide plate or carrier 104. Camming member 122, which is moved in
response to manipulation of control lever 64a, engages cam
followers 114d, 116d to position the lane-switching members 114,
116 in the same relative position. For the illustrated condition
wherein lane-switching member 114 would divert the next car along
crossover track 44, cam 122 will contact cam follower 114d and
swing the lane-switching member 114 into the same relative position
as lane-switching member 116. Thus, if the lead car at the end of
the race comes along the first or inner lane section 40, it will
pass along that lane section. If the trailing car happens to be
along the same inner lane section, the lane switching member 114
will have been switched by the first car into the illustrated FIG.
2 position whereupon the trailing car will move along crossover
track 44 and finish along the second or outer lane section 42. If,
however, the trailing car is moving along the outer lane section
42, lane switching member 116 will be in the appropriate position
to allow the car to pass along that section and finish separately
in its gate.
A typical sequence of operations will now be described in order to
facilitate a further understanding of the present invention:
In order to start the race, control lever 64a is placed in the
illustrated position to close gate members 52, 54 and the two cars
to be raced are placed along the inner and outer lanes 40, 42 with
their guide pins P being in the guideways and trapped by gate
members 52, 54 cooperating with stationary gate members 48, 50. The
signalling device 78 is balanced within the housing 76. In order to
start the race, control lever 64a is moved from the FIG. 2 position
toward the starting line S and into the dotted line position shown
in FIG. 3, whereupon gate members 52, 54 swing to their open
position and the cars traverse the racing course. In the dotted
line position of control member 64, car sensors 100, 102 are moved
away from coupling members 88, 90 as previously described. The race
continues for one or more laps until both cars pass the starting
line S and begin the final or flag lap at which time the operator
returns the control lever 64a to the illustrated position. This
moves the gate members 52, 54 to the lane blocking position, brings
the car sensors 100, 102 into operative relation to the coupling
members 88, 90 and cams the lane-switching members 114, 116 into
the same relative position. Assuming that the car along the inner
lane L.sub.1 approaches the finishing line F first, it moves past
lane switching member 114 switching it into the illustrated
position. Thereupon, its pin P comes into contact with depending
finger 88c of coupling member 88 pivoting the same to a position
wherein the support beneath shoulder 84 is removed and the
corresponding signal flag 78a is dropped (FIG. 6) to signal that
the car along the first or inner lane L.sub.1 has won the race. If
the trailing car happens to be along the inner lane, it will
automatically be switched to the outer lane by guideway 44 and
lane-switching member 114; and if it happens to be along the outer
lane, it will pass therealong. Both cars will end up in chocked
starting positions at starting line S for the next race. Prior to
initiation of the next race, the signal flag 78 is once again moved
to the balance position illustrated in FIG. 5 and the gate is ready
for its next operation.
A latitude of modification, change and substitution is intended in
the foregoing disclosure and, in some instances, some features of
the invention will be used without a corresponding use of other
features. Accordingly, it is appropriate that the appended claims
be construed broadly and in a manner consistent with the spirit and
scope of the present invention.
