Description
This invention relates to improvements in and relating to a toy
game machine which has a function analogous to playing cards.
Many toy amusement machines of this type have been proposed, and
most of them typically comprise a plurality of rotatable display
drums bearing suitable combinations of symbols on their respective
peripheral surfaces and a push button arrangement designed to stop
the drums successively so as to expose the symbols to view through
a display window for the purpose of pairing or otherwise matching
the various symbols on the drums. Conventional machines of this
description have been built in such a way that the symbols are
exposed to view immediately after the drums are held to a stop.
It is an object of the present invention to provide an improved toy
game machine of this character which incorporates mechanical
features masking a series of symbols until means are operated at
will to expose these symbols to view each independently of the
others, whereby the sense of amusement is increased manifold.
The machine according to the invention will now be described below
with reference to the accompanying drawings in which:
FIG. 1 is a perspective view of a toy game machine embodying the
invention;
FIG. 2 is a rear elevation of the machine with a rear cover removed
to expose its interior components;
FIG. 3 is a partially sectional side view showing a combination
brake-and-switch element as operatively associated with a display
drum and a selector push button;
FIG. 4 is a side view showing shutter means as operatively
associated with the selector button and as in a position to close a
display window; and
FIG. 5 is a side view showing the brake-and-switch element of FIG.
3 as operatively associated with a starter push button.
Referring first to FIG. 1, there is shown a toy game machine 100
which embodies the present invention. This machine includes a
housing 101 formed by a front cover 102 and a rear cover 103. The
front cover 102 is provided with a plurality of display windows 104
to expose to view the various combinations of symbols, hereinafter
described, with the number of said windows corresponding to the
number of display drums, hereinafter described. A plurality of
selector push buttons later described and a starter push button
also later described are arranged for handling on the front cover
102.
Referring to FIG. 2 which shows the various operating components of
the machine and to the remaining Figures, there are a plurality of
display drums 105 each bearing on its peripheral surface a suitable
combination of symbols 106. These drums are mounted for frictional
rotation with a shaft 107 journalled for rotation between sides of
a machine frame 108. The driving force to effect rotation of the
shaft 107, hence drums 105, is provided by a motor M through a
transmission unit generally designated at T. A toothed wheel 109 is
coupled to each drum 105 and provided peripherally with a number of
teeth 109' corresponding to the number of symbols 106 on the drum
105.
A pivotal shaft 110 extends between opposite sides of the machine
frame, parallel to the first mentioned shaft 107, for pivotal
movement about a horizontal axis. The shaft 110 has fixedly mounted
thereon a longitudinal plate member 111 which is provided at spaced
positions with a plurality of combination brake-and-switch elements
112. Each brake-and-switch element 112, as better shown in FIGS. 3
and 5, has at one end a hook 113 integral therewith and at the
other an L-shape contact lug 114. The element 112 is made
preferably of plastics or other insulating material. It is loaded
by means of a spring 116 to normally urge the hook 113 into
engagement with a tooth 109' of the toothed wheel 109 to thereby
discontinue the rotation of the display drum 105 associated
therewith. The lug 114 is engageable, when a starter push button
later desribed is depressed against the tension of the spring 116,
with a longitudinal frame member 108' of the machine frame to
thereby close a motor energization circuit not shown and thus
effect rotation of the drums 105 all at the same time.
Intermediate between and parallel with shafts 107 and 110, there is
provided a shaft 117 having rotatably mounted thereon a number of
masking or shutter means 118 corresponding to the number of windows
104, viz the number of symbols 106 and normally positioned to
conceal the symbols from view through the windows. The shutter
means 118 particularly shown in FIG. 4 includes a centrally arcuate
arm 119, a neck portion 120 extending outwardly thereof and mounted
on the shaft 117 subjacent the drum shaft 107, a dog-leg portion
121 extending from one end of the arm 119, a selector push button
later described, and an enlarged projection 122 extending from the
opposite end of the arm 119 substantially radially outwards
relative to the drum 105 and dimensioned to mask the window
104.
There are provided as many selector push buttons 115 as there are
drums 105, and each of these push buttons has its tab 115a normally
projecting on the front cover 102 as shown in FIG. 1. The selector
push button 115 is provided with a flange 123 with which to
restrict excessive outward movement of the push button and an
extending arm 124 integral therewith. The arm 124 has a horizontal
projection 125 extending from one side thereof and parallel with
the flange 123, thereby defining a pocket as at 126 for
accommodating the dog-leg portion 121 of the shutter means 118. The
arm 124 extending from the push button 115 is further provided with
a vertically elongated slit 127 thereby bifurcating the arm. The
bifurcated portions 124a of the arm 124 are resiliently inserted
through and supported in an opening 128 formed in the longitudinal
frame 108'.
A starter push button 129 is located at an extreme end of the front
cover 102 in a position wherein a tip end of its crank arm 130 is
held in abutting relation to the last one of a series of
brake-and-switch elements 112. More specifically, the tip end 130a
of the crank arm 130 is positioned intermediate between pivotal
shaft 110 and spring 116 so as to allow the element 112 to rotate
clockwise against the tension of the spring 116 when the starter
push button 129 is depressed.
With this construction, the game machine according to the invention
will be operated in the manner following.
The starter push button 129 is depressed, rotating a series of
brake-and-switch elements 112 all at the same time clockwise until
the contact lug 114 is brought into contact with the longitudinal
frame member 108', whereupon the motor energization circuit is
closed to drive all drums 105 simultaneously. The starter button
129 is continued to be depressed as long as the user wishes to keep
the drums 105 running. Upon release of the starter button, it is
retracted to its normal position under the influence of spring 116,
and at the same time, the elements 112 rotate counter clockwise to
a position wherein the contact lug 114 is disengaged from the frame
108' to thereby open the motor circuit and the hook 113 engages
with the toothed wheel 109 thereby to stop the drums. The selector
push buttons 115 are now depressed successively, rotating the
shutter means 118 counter clockwise, as viewed in FIG. 4, to a
position wherein the masking projection 122 is placed out of
registry with the window 104 so as to expose to view therethrough
the symbols 106 on each drum. Thus, the cycle of game may be
repeated by depressing the starter push button 129 so that all
selector buttons 115 are brought back into normal position as the
longitudinal plate 111 abuts against the ends of bifurcated
portions 124a and trips the buttons 115 outwardly. Designated at B
is a battery compartment connected to the motor M.
