In FIGS. 1 to 9, like portions or parts are designated with like
numerals.
Referring to the drawing in FIG. 1, there is shown a preferred form
of a fabricated endless track A, on which a toy vehicle B, for
example a locomotive, is adapted to travel, according to the
present invention. The endless track A is made up of a plurality of
straight and curved track sections 10, 11 and at least a bridge 12
which is composed of two bridge sections 12a, 12b.
Each of the track sections 10, 11 has a level portion 13 and a
vertical sidewall portions 14 which define said level portion. Each
of the sidewall portions is provided at its ends with a male joint
15 and a female joint 16, respectively so that these sections can
be interchangeably joined to each other by inserting said male
joint into said female joint. The level portion 13 is provided with
a plurality of apertures 17 for decorative purposes. Also, the
level portion 13 has upper and lower surfaces defined by said
vertical walls so that the both surfaces may be utilized as paths
for the vehicle B.
As shown in FIGS. 4 and 5, the bridge 12 is composed of two
symmetrical bridge sections 12a and 12b each including a bottom
portion 18, parallel spaced-apart sidewalls 19, 19 affixed to said
bottom portion and support portions 20, 20 extending downwardly
from said sidewalls, respectively. The bottom portion 18 and the
side rails 19, 19 form an inclined track section having a
substantially U-shape in cross section. One 12a of the bridge
sections is provided, at the lower end of its bottom portion 18,
with a pair of male joints 21, 21 and on the outer faces of the
upper ends of said sidewalls 19, 19 with a pair of female joints
22, 22. While, the other bridge section 12b is provided at the
lower end of its bottom portion 18, with a pair of female joints
21', 21' and on the outer faces of the upper ends of said sidewalls
19, 19 with a pair of male joints 22', 22'. Each of the bridge
sections 12a, 12b is provided with racks 23, 23 which provided on
the sidewalls 19, 19 of each bridge section. The two bridge
sections 12a, 12b are coupled to each other by inserting the male
joints 22', 22' in the female joints 22, 22, respectively.
In order to fabricate an endless track A as shown in FIG. 1, one
has only to connect the fabricated bridge 12 to a track formed by
connecting the straight and curved track sections 10, 11 together
in the manner depicted and previously described. To connect the
bridge 12 to the track thus formed, the male joints 21, 21 of one
bridge section 12a are inserted in the female joints 16, 16 of one
terminal straight track section 10, while the male joints 15, 15 of
the other terminal straight track section 10 are inserted in the
female joints 21', 21' of the other bridge section 12b. It is
needless to say, however, that the manner of assembling these
sections into an endless track A is not limited to such order.
Referring now to FIGS. 6 to 8, there is shown a preferred
embodiment of a toy vehicle B in the form of a locomotive according
to the present invention. The vehicle B is provided with a chassis
24 which has substantially rectangular frame 25 comprising parallel
sidewalls 26, 27 end walls 28, 29, and a bottom wall 30. The frame
25 is provided with a gear casing 31 which is situated at the
middle portion thereof. Within the frame 25 are also mounted an
electric motor 32 having an output shaft 32a on which a pinion 32b
is mounted, and a battery casing 33 for receiving a dry cell 34
which is in circuit with said motor.
The gear casing 31 supports a first shaft 35, a second shaft 36 and
a third shaft 37 for rotation, respectively. The first shaft 35 has
a crown gear 38 and a pinion 39 which are fixedly mounted thereon.
The second shaft 36 extends laterally outwardly through apertures
formed in parallel sidewall 31a, 31b of the gear casing 31 and
through apertures, formed in the sidewalls 26, 27 and has, on its
ends, fixedly mounted pinions 40, 40. The second shaft also has, on
an intermediate portion thereof, a toothed wheel 41 and a pinion 42
which are fixedly mounted. Similarly, the third shaft 37 extends
laterally outwardly through apertures formed in the parallel
sidewalls 31a, 31b and in the body 52 of vehicle and has, on its
ends, fixedly mounted pinions 43, 43 which are larger in diameter
than the pinions 40, 40 of said second shaft. The third shaft 37
also has, on its middle portion, a cam member 44 and, on its
intermediate portion, a toothed wheel 45.
The pinion 32b mounted on the output shaft 32a of the motor 32 is
in mesh with the crown gear 38 of said first shaft, the pinion 39
of the first shaft 35 is in mesh with the toothed wheel 41 of the
second shaft 36 and then the pinion 42 of the second shaft 36 is in
engagement with the toothed wheel 45, whereby the first, second and
third shafts 35, 36, 37 are rotated simultaneously as the motor 32
is actuated.
The sidewalls 26, 27 of the frame 25 are provided, in their front
portions, with elongated vertically extending slots, not shown. A
front axle 46 is rotatably and reciprocably mounted in said
elongated slots for the purpose of minimizing the drag which is
imparted to the motor 32 on curved track portions and for the
purpose which will be described latter. The front axle 46 carries a
fixedly mounted front wheel 47 on each end thereof. The front wheel
47 is provided, on its outer periphery, teeth 48, which are adapted
to engage the pinion 40 of said second shaft, which is situated
immediately above the front wheel 47, so that the front wheels 47,
47 can be supplied power for driving the vehicle B by the motor 32
through the gear train comprising pinion 32b, crown gear 38, pinion
39 and toothed wheel 41. A rear axle 49 is secured to the rear
portions of the sidewalls 26, 27 of frame 25 and a rear wheel 50 is
rotatably mounted on each end of the rear axle 49. Each rear wheel
50 has on its outer face, an eccentric projection 50a to which one
end of a reciprocating arm 51, is rotatably fixed by means of a pin
50b so as to reciprocate the arm 51 when the wheel 50 is
rotated.
In the illustrated embodiment, the locomotive B is provided with a
body 52 having a funnel simulating member 53. This funnel 53 is
vertically reciprocably mounted through a circular aperture 54
formed in a top wall portion adjacent to the front end of the body
52. The funnel 53 is of a hollow structure and has at its lower end
a horizontally extending rectangular lug 55 and a vertically
extending rectangular plate 56. The rectangular lug 55 has an
elongated horizontally extending aperture 55a in which a portion of
the cam member 44 of the third shaft 37 is adapted to be received
as shown in FIG. 6. The vertical rectangular plate 56 is slidably
mounted in a rectangular guide socket 57 projecting upwardly from a
front portion of the chassis 24 so that the plate 56 can be
vertically guided by the socket 57. The funnel 53 is normally
biased downwardly by the action of a coil spring 58 one end of
which is secured to the lug, not shown, provided on a lower portion
of the inner face of the funnel 53 and the other end of which to a
rod 59 transversely mounted in the front portion of the body
52.
As shown in FIG. 8, an opening 60 of the battery casing 33 is
provided, for replacement of a dry cell 34, in a portion adjacent
the rear end of the bottom 30 of said frame 25. The opening 60 is
opened and closed by a cover member 61 which is pivotally mounted,
at the ends of its arm 61', in notch bearings 62, 62 provided on
the rear end of the bottom 30. The cover member 61 is provided with
a conductive switch lever 63 which is rotatably fixed to the
reverse side thereof by a pivot 64. The switch lever 63 has a
spring-loaded contact, not shown, which is adapted to contact the
terminal of the dry cell 34, and is adapted to come into contact,
at one end thereof, with a contact 65, which is in circuit with the
motor 32, by turning the lever 63. In other words, when the lever
63 is in "ON" position, the motor circuit is closed, and when it is
in "OFF" position the circuit is open, The switch lever 63 serves
also as a locking means for the cover member 61 in such a way that
when the inner end of the lever 63 is rotated anticlockwise after
it has been retracted into a recess 66 which is radially formed in
a circumferential portion of the opening 60 of the bottom wall 30,
it is brought into engagement with an upper edge portion of the
bottom wall 30, by which a semiarcuate recess 67 is defined, to
hold the cover member 61 in closed position, and that when the
lever 63 is turned clockwise until the inner end thereof comes in
the square-shaped recess 66, it is disengaged from said engaging
portion, thereby enabling the cover member 61 to be opened.
It is to be noted that, according to the present invention, almost
all of the track sections 10, 11, bridge sections 12a, 12b and
vehicle B can be made of suitable plastics materials, except
electrical switch members and a few other parts in the vehicle
which are essentially required to be of metal.
In operation, the vehicle B put on the endless track A is made to
run along it. As long as the vehicle B travels on the level track
portion composed of the straight and curved track sections 10, 11,
it runs with the front and rear wheels 47 and 50 the outer
peripheries of which are in contract with the level surface 13 of
the track. When the vehicle B crosses the bridge 12, it runs with
the pinions 43, 43 of the third shaft 37 which engage the racks 23,
23 of the bridge 12. More specifically, when the vehicle B runs on
the level track portion, it is driven by the front wheel 47 rotated
by the pinions 40, 40 of the second shaft 36, which are brought
into mesh with the teeth 48 of the front wheels and to which the
motor power is supplied through the gear train aforementioned. When
the vehicle B climb and leaves the bridge 12, it is driven by the
pinions 43, 43 to which the motor power is transmitted through the
reduction gear train previously explained, without the aid of the
drive wheels 47, 47.
While the motor 32 is kept rotating, the cam member 44 is kept
rotating with the third shaft 40 and causes the funnel 53 to make
up-and-down movement by mechanically raising and lowering the
horizontally extending rectangular lug 55 of the funnel 53. That
is, as the cam 44 is rotated clockwise, each of the camming
surfaces thereof engages the lower surface of the lug 55, adjacent
the free end thereof, to raise the lug 55 with the funnel 53
against the action of the spring 58, and then disengages from said
lower surface by escaping into the elongated aperture 55a of the
lug 55 to permit the funnel 53 to be pulled downwardly by the
action of the spring 58. In these cases, the vertically extending
rectangular plate 56 of the funnel 53 slides vertically in the
guide socket 57 by being guided by the latter, thus enabling the
funnel 53 to be vertically reciprocated during travel of the
vehicle B. Further, the cam member 44 coacts with the lug 55 and
the spring 58 to emit a pleasant sound every time when the funnel
53 comes down, since the lower surface of the lug 55 is forced to
strike against the cam 44 by the action of the spring 58 at that
time.
As may be seen from the foregoing description when the vehicle B
crosses the bridge 12, it is driven by the gears 43 engaging the
racks 23 under considerably reduced speed and it can not only
surely cross the bridge, but also considerably decrease consumption
of the dry cell 34 due to decrease of resistance through the motor
32, since the driving wheels 47 are, at this time, lowered with the
axles 46 thereof by weight and disengaged from the pinions 40 of
the second shaft 36 and, as a result, the load imposed upon the
motor 32 is considerably decreased. Further, as the vehicle B runs
on the track A while imparting to the funnel 53 vertical
reciprocation, children can play enjoyably with it.
Thus, the toy as described, according to the present invention, not
only is very simple to assembly and operation, and attractive in
appearance, but also has such various advantages, affording the
so-called high play value.
