INVENTOR. ARTHUR W. HENKSON BY M5149 ATTORN EY 3,481,071 REMOTE CONTROL TOY Arthur William Hinkson, 45 Jervis Ave., Farmingdale, N.Y. 11735 Filed Mar. 16, 1966, Ser. No. 534,743

Int. Cl. A63h 33/26 I U.S. Cl. 46-240 11 Claims This invention relates in general to remotely controlled toys, and more particularly to a toy vehicle, boat, or the like which is moved about a board by manipulation of a mechanism.

A main object of this invention is to provide an amusement device having a board on which a toy boat, vehicle, figure, or the like may be directed by the manipulation of seemingly un-connected controls.

Another object of this invention is to provide an amusement device or toy which gives rise to a unique sensation of the remote control of an object on a board.

A further object of this invention is to provide a mechanically activated remotely controlled vehicle, boat, figure, or the like which may be maneuvered over a board according to the skill of an operator.

Still another object of this invention is to provide a mechanical linkage to remotely move a toy about a board, the linkage reaching the entire operating surface of the board and greatly magnifying the control motions of an operator.

Yet a further object of this invention is to provide an inexpensive toy which provides a greater pleasure, thrill of use, and requirement of skill than other more costly, elaborate, and complex amusement devices.

An additional object of this invention is to provide a remotely controlled toy vehicle which may be driven mechanically on a board by a remote control device which presents the natural appearance to an operator of an automobile steering wheel.

A feature of this invention is the provision of a parallel bar mechanism which expands and contracts, known as a lazy tong mechanism, below a board to move a toy on the board about the board by means of a magnet, the lazy tong mechanism having a free and a secured end, the magnet being fixed to the free end of the lazy tong mechanism and control means being attached near the secured end of the mechanism to amplify movements of the control means.

Many other objects, advantages, and features of invention reside in the particular contruction, combination, and arrangement of parts involved in the embodir FIG. 2 is a bottom view of a toy boat which may be used with this invention;

FIG. 12 is a section taken on line 1212 of FIG. 10; and

FIG. 13 is a section taken on line 13-13 of FIG. 8 with the bottom cover shown in position.

Referring to the drawings in detail, FIGS. 1-5 show the first embodiment of my invention which has a board 20 of plastic, fiberboard, or the like. Board 20 has a bottom cover 21 fixed under it by screws 22 which enter brackets 23. A parallel bar or lazy tong mechanism 24 is pivotally secured by a screw 25 to a boss 26 near one corner of board 20. Two

long restraining links

27 and 28 are connected to the pivot 29 nearest screw 25. The pivotally mounted

links

30 and 31 are attached to board 20 by screws 32 and 33. Control links 34 and 35 have ends attached, respectively, to the pivot 36 between

links

27 and 30 and the pivot 37 between

links

30 and 31.

Two

control disks

38 and 39 are rotatably secured on board 20 by screws or

rivets

40 and 41. Arcuate slots 42 and 43 are cut in board 20 below the

disks

38 and 39. Screws or the like 44 and 45 extend from

disks

38 and 39 to control links 34 and 35.

As shown in FIG. 4, mechanism 24 terminates in a pivot point 46 below which is fixed a glide type bearing 47 which slides freely on bottom cover 21. Mounted on a flat spring 48 above pivot 46 is a magnet 49. Spring 48 holds magnet 49 against the underside of board 20. As shown in FIGS. 1, 2 and 4, a small boat 50 of wood or a like material having a magnetic element 51 glued below it is placed on board 20.

The first embodiment of my invention is used as follows. The boat 50, a toy lighthouse 53, a breakwater 54,

buoys

55 and 56, and like objects, are removed from the attached box 57 and placed on the effective area 58 marked on board 20. Area 58 may be painted to simulate Water if desired. Turning the

control disks

38 and 39 moves the magnet 49 below the effective area 58 by means of the mechanism 24. Thus manipulation of

disks

38 and 39 can move boat 50 about the objects on board 20.

Referring now to FIG. 3, it may be seen that the

restraining links

27 and 28 are of great length. Thus when only disk 38 is moved, disk 39 being stationary, pivot point 29 will move on the circumference of a relatively large circle in substantially a straight line. Therefore, it may be seen that the selective manipulation of

disk

38 or 39 moves magnet 49 in substantially straight paths at right angles to each other. Simultaneous manipulation of the

control disks

38 and 39 moves the magnet 49 and thereby boat 50 along a path at a resultant angle. Magnet 49 is restrained to move only under effective area 58 by the length of the arcuate slots 42 and 43 Which limit rotation of

disks

38 and 39.

The forces required to move mechanism 24 and boat 50 are very small. For this reason the motion of the

control disks

38 and 39 may be greatly magnified by the mechanism 24. This magnification of the control motions gives the user of this embodiment of my invention the sensation that there is no understandable mechanical connection between the

control disks

38 and 39 and boat 50 to provide a unique experience of remote control.

Referring now to FIGS. 6, 7, 8, 9 and 13, the second embodiment of my invention has a board 60 below which there is fixed a bottom cover 61. An effective area 62 marked on board 60 has

toy automobile accessories

63 and 64, and houses and garages 65 and 6-6 placed on'it.

When these articles are not being used, they may be kept in the box 59 fixed to board 60. One or more raised

parking areas

67 and 68 are glued to board in area 62.

Toy automobiles

69 and 70 each have free turning rear wheels 71 and a magnetic element 72 in their front ends. A lazy tong mechanism 74 has a magnet 75 fixed over its endmost pivot point 76 by a spring member 77. Thus as mechanism 74 moves magnet 75 about below the effective area, it draws a toy automobile along over board 60.

As shown in FIGS. 6, 8 and 9, a long restraining link 78 is pivotally fixed by a screw 79 to boss 80 of board 60. A control unit, generally designated by the reference numeral 81, has a housing 82 fixed to board 60. A hollow shaft 83 is rotatably fixed in housing 82 by means of a collar 84 or the like. Shaft 83 has a wheel 85 fixed to its outer end and a crank arm 86 fixed to extend downward from its inner end through a slot 87 in board 60. A link 88 is fixed to arm 86 and is pivotally connected to the fixed end of mechanism 74 through a straight slot 89 in the offset guide plate 90. Guide plate 90 is fixed below board 60 by screws 91. Thus it may be seen that rotation of wheel 85 moves the fixed end of mechanism 74 laterally to move the free end of mechanism 74 and magnet 75 laterally in the same direction as wheel 85 is turned.

Referring further to FIGS. 6, 8 and 9, a center shaft 92 extends through shaft 83 and has a plate or disk 93 fixed to its outer end within an opening 94 in the center of wheel 85. A downward projection 95 from the inner end of shaft 92 extends through slot 99 to be fixed to restraining link 78. The free end of restraining link 78 is connected to the first pivot point 96 of mechanism 74. A tension spring 97 urges the free end of link 78 upward to retract the mechanism 74 longitudinally. Thus pressure on plate 93 moves magnet '75 outward and relaxation of this pressure allows spring 97 to move it inward. The Wheel 85 and disk 93 of control unit 81 are very natural to use. The wheel 85 is grasped by the fingers of both hands with the thumbs resting on disk 93.

In this manner the user of the second embodiment of my invention may drive a

car

69 or 70 about area 62 in a very realistic manner. Since the movements of control wheel 85 and plate 93 are greatly magnified by mechanism 74, a unique sensation is obtained to the extent that it is hard to believe that a mechanical linkage exists between the controls and a driven toy car. One car may be parked by moving it against a raised

parking area

67 or 68 and then shifting magnet under another car.

FIGS. 10, 11 and 12 show a modification of the second embodiment of my invention. Wheel 100 of control unit 101 is fixed to outer shaft 102 which is rotatably mounted in housing 103. A lazy tong mechanism 104 has one end pivotally fixed to boss 105 by a screw 106. A square or splined shaft 108 extends through shaft 102 and has a crank 109 fixed to it. The free end of crank 109 extends through opening 115 in board 107 and is connected to the first pivot point 110 of mechanism 104 by a suitable bracket 111. The outer end of shaft 108 has a plate (not shown) fixed to it within wheel 100 similar to plate 93 within wheel 85. A tension spring 114 tends to retract mechanism 104 longitudinally. Thus rotation of wheel 100 moves the free end of mechanism 104 laterally while depression of its plate moves it longitudinally. Since opening 115 is rectangular and limits movement of the end of crank 109 to a rectangular area, opening 115 limits the much greater movement of the free end (not shown) of mechanism 104 to a rectangular elfective area.

The lazy tong mechanism of this invention may have a greater or lesser number of pivot points or quadrilateral sections depending on the particular configuration of a given embodiment of my invention. In all cases, however, the mechanism should amplify the control motions imparted to it to give rise to the unique sense of remote control provided by my invention.
