The present invention relates to animated toys, and particularly to those designed to simulate insects, and an object is to provide such a toy which has amusing characteristics not heretofore known.
Such toys in the past have tended to either employ an excessive number of parts so as to be of doubtful reliability and durability, or to be over-simplified, so as to United States Patent be unlifelike and uninteresting. Furthermore, there has often been present a winding key or handle, which is either promptly lost or which if not removable tends to destroy the illusion that the toy is a real live creature. There has also been a lack of variety in the motions of the toy. Accordingly, the principal object of the invention is to furnish an animated toy, simulating a large insect, which will have a comical walking movement; in which there is no projecting winding key or other incongruous control, visible when the toy is in motion; which is composed of a minimum number of relatively rugged parts, and which, if struck, will change its rate of movement, and appear to attempt to run away.
The manner in which this object is accomplished is fully described in the following specification and illustrated in the accompanying drawings in which:
FIGURE 1 is a perspective view of the toy;
FIGURE 2 is an enlarged plan view of the toy with parts removed and others in section;
FIGURE 3 is an enlarged left side elevation with the casing broken away to expose the interior mechanism;
FIGURE 4 is an enlarged vertical sectional View on the line 4-4 of FIGURE 2 with parts broken away; FIGURE 5 is an enlarged sectional view on the line 5-5 of FIGURE 2; and
FIGURE 6 is a View of elements of the drive mechanisrn. t
Similar reference characters have been applied to the same parts throughout the drawings and specification.
The toy selected to embody the present invention is in the form of a caricature of a bug or insect and comprises basically a hollow body portion 10, as seen in FIGURE 1, having a head 12 providing a nose 14 and eyes 16; and antennae 18 may be included, all calculated to give the toy a rather grotesque and yet comical appearance. A tall 26 is substantially rigid with body portion 10, and normally rests on the floor or supporting surface. At either side of body 10 is a propelling leg unit 22 which comprises a hub 24 supported for rotation relatively to body portion 10, and having rigidly fixed therewith a plurality of legs 26 which project away from body 10 and in relation to the axis of hub 24 in the positions of the elements of a cone. The outward or oblique angle of legs 26 relative to the axis of hub 24 is such that at least one leg 26 on each side always projects in an outward direction but sutficiently downwardly to be in supporting relation to the floor or supporting surface to support the body 10. When the leg units 22 are slowly rotated, the toy will partake of a peculiar wobbling kind of walking movement, not unlike that of a June-bug, or similar large insect. The torque imparted to body It) by any mechanism for rotating leg units 22 is resisted, and body It) is prevented from overturning, by contact of tail with the floor or supporting surface over which it slides when the bug is in motion.
3,226,878 Patented Jan. 4, 1966 It is contemplated that legs 26 may be flexible or springy if desired to give more character to the move ment.
As hereinbefore stated, the bug is driven by a spring motor concealed in body 10, and one of the advantages of the construction is the fact that the spring motor is wound by the simple reverse rotation of the leg units. It is, therefore, unnecessary to have any type of winding key or control in evidence on the outside of body 10.
Body 10 consists of a thin outer shell 32 (FIGURES 2 and 3) which may be made most conveniently of one of the easily moldable plastics of which many are wellknown. Shell 32 has a rib or bulkhead 34, which engages a neck portion 36 of head 12, thereby helping to secure the head to the body. In similar manner a rib or bulkhead 38 cooperates to secure tail 20. Other ribs or bulkheads 40 and 42 fit and cooperate with a frame 44 of a spring motor generally designated as 46. Motor 46 drives a one piece shaft or axle 48 which extends outwardly from opposite sides of the frame 44 into fixed engagement with the hubs 24 carrying the two sets of legs 26.
Within motor frame 44 a spiral spring 58 has an end .60 anchored on frame 44, its other or inner end being anchored on a spring arbor 62 in any suitable or wellknown manner. Arbor 62 is journalled in bearings 64 and 66 mounted in frame 44, and has fixed therewith a first gear 68, which meshes with a second gear 70 fixed on axle shaft 48. Axle shaft 48 and spring arbor 62 are, therefore, connected together in such manner that rotation of one must rotate the other.
Gear '76 includes a projecting circular hub portion 72 mounting a freely rotatable gear '74 (see also FIG- URE 6) having circularly arranged openings '75 through its face for coaction with a spring ratchet element 76 which is keyed or otherwise fixed to snaft 48 in facing engagement with gear 74. Ratchet element 76 includes a pair of angularly bent ears 77 disposed in the path of openings 75 and bent so that rotation of element 76 in one direction (clockwise in FIGURE 4) permits the ears 77 to slide over the face of gear 74, whereas counterclockwise rotation of element 76 results in the ears '7"! entering a pair of the openings 75 to provide a positive driving relation between ratchet 76 and gear 74. Consequently, rotation of legs 22 in a clockwise direction will serve to wind spring 58 without disturbing gear 74, whereas release of the tensioned spring 58 will drive shaft 48, through gears 68 and 70, in a counterclockwise direction and thereby establish a positive driving relation between ratchet element 76 and gear 74.
The mechanism so far described would tend to actuate leg units 22 too fast for a natural crawling appearance, so a governing device is provided as follows.
Third gear 74 meshes with and drives a first pinion 73 which is fixed in relation to a fourth gear etl supported for rotation on a shaft 32 carried in frame 44. Gear 8t meshes with and drives a second pinion 84 fixed in relation to a fifth gear 86 fixed on a shaft 83 carried in frame 44 for rotation.
Fifth gear 86 meshes with and drives a third pinion @2 fixed in relation to a gear $4 on a shaft 96 rotatably carried in frame 44. Gear 94 in turn mesh-es with a fourth pinion 97 rotatably carried on shaft 88. A detent or pawl 8 (FIGURE 3), providing a stop level for the drive mechanism, is pivotally supported on a rivet or the like 16%) on frame 44 and includes an ear portion 1% engageable with the teeth 164 of sixth gear 94 by swinging of detent 98. Detent 98 has an arm or lever 1% which projects preferably through the undersurface of body 10 so as not to be noticeable during the movement of the bug. It will now be apparent that the speed reduction 12.9 gears will be locked whenever detent d8 is engaged with gear 94.
In order to provide further speed control means, pinion 97 has integrally formed therewith a governor cam 94) which is generally triangular in configuration, as best seen in FIGURE-S 3 and 5, and a yoke 183 is pivotally supported in position for engagement with the cam by means of a pin or the like 1149 on a carrying lever 112 which is fulcrumed on a tongue 114 turned out from the side of frame 44. Yoke 168 provides a notch or interior space 116 which loosely fits about governor cam 98 so that rotation of the cam will swing yo-ke 1G8 rapidly back and forth about pin 110. The rapid motion introduces a substan tial degree of friction between the cam and yoke and, of course, controls the speed of rotation of pinion 97 and the gear train associated therewith, so that the speed of drive shaft 48 and the legs 22 fixed thereto is kept approximately within a predetermined range. However, it is intended that the governor shall be disabled from time to time, which action will now be described.
Carrying lever 112 may be swung upwardly about fulcrum 114 as shown in dotted lines in FIGURE to a position wherein yoke 1% is removed from cam 99, in which case cam S t) and pinion 97 will be released for freer rotation and the motor will speed up to a much faster rate than with the governor in operation. This is to give the bug the capability of running away when struck by the hand or any suitable object. When lever 112 is raised so yoke 168 is out of engagement with cam 9%, the yoke is prevented from swinging too far out of line by tongues 118 bent in from the upper edge of lever 112 to engage the upper edge of the yoke if it swings excessively, but to allow complete freedom to follow cam 90 at other times. Lever 1.12 has a tongue 120 extending outside of frame 44- through a notch 122 to slidingly engage the edge of the notch to guide lever 112 against sideward displacement. It is to be noted that the rapid movement of yoke 108 will make a distinct rattling noise which will add to the grotesque eifect of the toy.
Carrying lever 112 has an arm 124 extending from fulcrum 114 in the opposite direction from yoke 103, arm 124 being resilient and having a detent button, dimple or the like 125 pressed by the resiliency of arm 124 into following engagement with a cam groove 126 formed in first gear 68, which in the present instance is concentric with spring arbor 62. Lever 112 is thus held stationary so long as detent 125 is in engagement with groove 126. However, in view of the resiliency of arm 12-4, detent 125 is rather easily dislodged from cam groove 126. A strut or upright 128 extends generally upwardly from arm 124 through a suitable opening in the top of body portion and is guidedly held in position by a tube or sleeve 127 fixed to and extending upwardly from the body. The upper end of upright 12S engages a simulated wing 132 which it maintains in a raised position above body 1%. Wing 132 has a combined sliding and pivotal connection 134 with body 10 so that the wing may pivot downwardly if sulficient force is exerted thereon to dislodge detent 125 from groove 126. Wing 132 constitutes a control or an impact receiving element. Thus, if someone swats the bug and hits wing 132, arm 128 is depressed and governor yoke 168 will be removed from cam 96 and the governor will be disabled. Thus the bug will speed up and appear to run away from its tormenter.
The shifting of lever 112 will be limited by contact of arm 124 with spring arbor 62, and detent 125 will come to rest in a position to be engaged with a snail-cam groove 136 which starts near arbor 62 and winds outwardly until it intersects hereinbefore mentioned cam groove 126. After detent 125 is dislodged as above described, some portion of groove 136 will engage it quite promptly, particularly in view of the increased speed of the parts, and detent 125 will be gradually shifted back into cam groove 126, restoring yoke 1 38 to engagement with cam 9t), and restoring the action of the governor. The bug will then go back to its slow pace until such time as it is again struck.
The operation of the device is thought to be clear from the above, sufficient to say the spring is wound by the simple expedient of turning one of the leg units backward while the stop control is engaged. If the bug is struck so as to contact the upstanding wing, it will run away temporarily. The leg-wheels are eiiective to give the bug a comical waddling motion, and a convenient start and stop control has been provided on the underside of the body where it does not detract from the desired appearance.
While this invention has been described with reference to certain features, structure and material in a particular environment, it will be apparent that various modifications might be made without departing from the principles of this invention.
