United States Patent() lCe Fig. 6 is a transverse sectional view taken substantially along the line 6 6 of Fig. 5.

Referring now more particularly to the drawings,` and specifically to Fig. l thereof, the embodiment of the inventionillustrated therein comprises I.a wheeled vehicle, generally designated 10, and a launchingmechani'smor structure, generally designated 11. The' vehicle 10 cornprises a body 12` havinga front end or nose 13, a rear end member 14, a pair of coaxial, ground engageable front wheels 15, 15,.,and apair of coaxial groundengageable rear 4wheels 16, 1'6.

The vehicle body 12 is of longitudinally elongate, hollow construction, and fabricated essentially of a downwardly concave,` upper shell or section 19, and an-.upwardly concave, lower shell or section 20, shaped complementary to and disposed in edge to edge meeting relation with the upper shell. v 4

In Fig. 2, the upper body section 19 is shown only in dot-and-dash outline, and the interior of the lower `body section 20 is clearly seen. Thelower body` shell is formed with a generally semi-circular front wall section 21 which combines withthe adjacent portion 22 of the lower shell to define an outwardly opening groove 23 of generally semi-circular configuration, andextending along the marginal portion` of the front wall section. Also in the front region of the lower shell 20, rearwards of the front wall section 21, are formed a pair of opposed, laterally outwardly extending axle or journal bearing portions 24, Z4, while a pair of laterally opposed cutouts 25, 25 open through the upper edge of the` lower shell in the rearward region of the latter; Airear wall section 26, of generally semi-circular configuration, extends` across the rear-end of the lower shell 20, and combines with the adjacent lower shell portion 27 to define `an outwardly opening, semi-circular groove extending along the periphery of 'the rear Wall section. Medially of the rear wall section `26, and opening through the upper edge thereof, is formed a through aperture or opening 29; and, at spaced points along the upper edgeof the lower body shell 20 are provided upstanding lugs or pins 30 for locating and securing the upper shell 19 in complementary, edge` to edgefrelation with respect to the lower shell.

The upper body section or shell 19 has its lower .peripheral edge or rim shaped for substantially conforming engagement with the upper edge of rim of the lower shell, and is further formed with `generally semi-circular front and rear end wall sections 33 and 34, which` combine, respectively, with the front and rear end wall sections 21 and 26 of the lower shell to define generally circular front and rear body end walls. in addition, the upper front wall section 33 combines with the adjacent portion 35 of the upper Shell 19 to define an outwardly opening, generally semi-circular groove 36, while the upper rear wall section 34 Acombines with the adjacent upper shell portion 37 to define an outwardly opening, i generally semicircular groove 38. With the` upper and lower body shells 19 and 2t) arranged in their lassembled relation to define the hollow vehicle body, the semi-circular lower and upper front grooves'23: and 36 ar-e in substantial alignment with each other and `define a generally annular groove circumferentiallygirding the front region of the vehicle` body,` while the upper` and lower,.semicircular rear grooves 3S and 2S align to define an external, aunular `groove circumferentially gir'ding the rear region of the vehicle body.

Extending laterally outwards from opposite portions of the upper shell 19, in the front region thereof, are a pair of axle or journalv bearing portions 41, each of which cooperates with one ofthe axle bearing portions 24 to journal the front wheel axle 42 and properly retain the locating member or tube 43 circumposed about the axle.

When the vehicle 10 is intended to simulate a jet car, airship, or the like, the upper shell 19 may be provided on opposite sides with sweptback wings 46, 46 (shown in dot-and-dash outline in Fig. 2) each shaped, as at 47', 47 (see Fig. 1) to receive and cover one of the rear wheels 16, 16. Further, a rearwardly disposed, upstanding tail 48, and a forwardly disposed dome or bubble 49 may be provided on the upper shell 19, being formed integrally therewith, or formed separately from the upper shell and secured to the latter.

i The nose 13 is of generally conical or conoidal shape, preferably fabricated of somewhat flexible, resilient material, such as polyethylene or the like, and is formed on its larger end with an inturned, peripherally extending lip or ange 52. In assembly, the larger rearward end of the nose 13 is distended to engage over the upper and lower front wall sections 33 and 21, so that the lip 52 snaps in to the grooves 36 and 23. In this manner, the front regions of the upper and lower shells 19 and 2t) are held Vin their complementary relation by the nose 13.

At the rear of the vehicle body 10, the rear end mem-= ber 14 preferably comprises an annulus or ring formed of resilient material, such as polyethylene or the like, and having an internal annular groove 54 which defines an internal, peripheral lip or flange 55. The ring 14 is radially sustained for peripheral engagement about the upper and lower rear wall sections 34 and 26, and upon release, the flange or lip S engages in the annular groove defined by the semi-circular grooves 38 and 28 to retain the rearward region of the body in assembled relation.

Interiorly of the lower shell 20, and preferably formed integrally therewith, are four rectangularly arranged upstanding studs, bosses or pins, including a laterally spaced forward pair of 58, 58, and a laterally spaced rearward pair 59, 59, all disposed longitudinally centrally of the vehicle body, intermediate the front wheel axle 42 and rearward cutouts 25. An additional, laterally spaced pair of upstanding studs, pins or bosses 60, 60 is formed interiorly of the lower shell 20 rearwards of the cutouts 25 and in substantial alignment with the pins 58 and 59, longitudinally of the vehicle body. In the space intermediate the pins 58 and 59, the lower shell 20 is open, reticulated or apertured, as at 61; and, an upstanding, hook-shaped retaining member 62 is formed interiorly of the lower shell intermediate and just forwardly of the front pins or studs 58, and having its upper portion 63 `bent or hooked rearwards at an elevation slightly above the upper ends of the latter pins.

A pair of upstanding, locating bosses or studs 66 and 67 are also formed interiorly of the lower shell 20, forwards and rearwards, respectively, of the cutouts 25. The for- Ward locating stud 66 is disposed intermediate the supporting pins 59, and the rearward locating stud 67 is disposed intermediate the supporting pins 60. However, the locating studs 66 and 67 have their upper ends disposed above the upper ends of the supporting pins 59 and 60. On opposite sides of the locating stud 67, the bottom or under portion of the lower shell 20 is depressed or recessed downwards to provide a pair of longitudinally extending, laterally spaced shoes 0r skids 68, 68 protruding from the underside of the vehicle body. The rearward end surface 69 of each shoe 68 is disposed at a rearwardly inclined angle, and, a pin 70 is embedded in the locating stud 67 and has its lower end depending into the space between the shoes 68, 68.

A generally rectangular plate 73 is disposed horizontally, in spaced relation within the lower body shell 20 and supported in its corner regions on the upper ends of the pins 58 and 59. The plate 73 is preferably cut away at its rear end for receiving the stud 66, and has its front end notched or cut away at 74 for engagement under the upper end portion 63 of the hook-shaped member 62. As best seen in Fig. 3, the plate 73 is disposed directly above the apertures 61; and further, a generally circular intermediate portion 75 of the plate 73, disposed imme diately over the apertures 61, is upset or elevated to define a vibratory sonorous diaphragm.

Disposed rearwards of the diaphragm plate 73, within the rearward portion of the vehicle body 10, is a motor frame, generally designated 78. The frame includes a longitudinally extending, horizontally disposed bottom wall 79 having a relatively large central opening 80, and a pair of relatively small openings 81 and 82 disposed, respectively, forwards and rearwards of the opening 80. The forward portion of the bottom wall 79 is seated on the rearward portion of the plate 73 with the locating stud 66 received in the forward aperture 81, and the rearward portion of the bottom wall is seated on the upper ends of the pins 60, 60 with the aperture 82 receiving the locating pin or stud 67. A single threaded fastener or screw 85 extends through the forward portion of the bottom wall 79, the underlying rearward portion of the plate 73, and into one of the supporting pins 59, and combines with the locating stud 66 and retaining member 62 to prevent lateral shifting of the diaphragm plate.

Extending through the rearward portion of the frame bottom wall 79 are a pair of threaded fasteners or screws 86, which threadedly engage in the supporting pins 60 and combine with the fastener 85 to tix the bottom wall upstanding rear wall 88 extends transversely of the side of the motor frame in position.

The motor frame also includes a pair of longitudinally extending, parallel spaced upstanding side walls 87 and 90 along opposite side edges of the bottom wall 79. An walls along the rear edge of the bottom wall, and an upstanding plate portion or tab 89 extends along the rearward margin of the bottom wall opening 80 forwardly of and in facing spaced relation with respect to the rear wall.

The rear wheels 16, 16 are disposed outwards, respectively, of the cutouts 25, 25 and rigidly connected together by a rod or axle 92 which extends rotatably through the motor frame side walls 87 and 90, and spacedly through the cutouts 25. That is, the rod or axle 92 is disposed over the opening 80, being rotatably mounted or journaled in the frame sidewalls 87, and and has its opposite ends extending spacedly through and outwards beyond the cutouts 25, 25 for connection to the wheels 16, 16. Fxedly circumposed about the axle 92, adjacent to but spaced inwards from the frame side wall 87 is a relatively small spur gear or pinion 93, while a relatively large spur gear 94, having an enlarged hub 95, is iixedly circumposed about the latter axle be tween the pinion and frame side wall 87. The pinion 93 and gear 94 are thus fixed relative to each other, and may, together with the enlarged hub 95, be formed as an integral unit, if desired. As seen in Figs. 2 and 4, the hub 95 is disposed in engagement with the inner face of the side wall 87, and permits rotation of the axle 92 while preventing shifting movement of the latter in one direction, to the left as seen in Fig. 4. Formed on the rod or axle 92, just outwards of the frame side wall 87, are a plurality of protuberances 96, which permit the axle to rotate and restrain the latter against shifting movement to right, as seen in Fig. 4. Thus, the motor frame 78 rotatably supports the rear axle 92, and the gears 93 and 94 are disposed within the frame and carried by the axle for rotation with the latter.

Disposed .in parallel, forwardly spaced relation with respect to the axle 92, over the frame opening 80, and having its opposite end portions rotatably supported in the frame side walls 87 and 90 is a rod or shaft 98. A relatively heavy fly wheel or inertia member 99, having an enlarged hub 100, is iixedly circumposed about the shaft 98 with the flywheel hub adjacent to the frame sidewall 90, while a relatively small spur gear is iixedly located about the shaft 98-in meshing engagement with the gear 94 and disposed adjacent to the frame side wall 87. A relatively large spur gear or radially toothed member 102 is xedly circumposed about the shaft 98 intermediate the ily wheel 99 and spur gear 101, so that that fly wheel and gears 101 and' 102 combine to define `a rotary inertia unit, the y wheel hub 100 and relatively small gear 101 being engageable with opposite frame side walls to retain the shaft in its journaled condition.

Rotatably supported in the rear frame wall 8S, and the upstanding tab 89 is a longitudinally extending shaft 104. On the forward end of the shaft 104, rearwards of the axle 92, is fixed a crown gear 105 disposed in meshing engagement with the pinion 93, while the rearward end of the shaft 10d is provided with a rearward facing coupling element or socket 106 intadjacent relation with respect to the rear body wall opening 29. More particularly, the coupling element or socket 106 comprises a fiaring, cup-shaped member, preferably fabricated of polyethylene or other suitable material, and lxedto the shaft 104 opening rearwards through the rear wall opening 29 for receiving a turning member, as will be described presently.

Upon rotation of the coupling element 106, which rotates the shaft 104 and crown gear 10S, the pinion 93 is driven by the crown gear and causes simultaneous rotation of the gear 94, axle 92 and wheels 16. Further, the gear 94 drives its meshing pinion 101 which effects rotation of the fly wheel 99 and the radially toothed member or spur gear 102. The flywheel and other rotating parts of course serve to drive the wheels 16 in the manner of an inertia motor.

An elongate somewhat resilient diaphragm operating member, strip or arm 108, see Fig. 3, extends forwardly and rearwardly of the vehiclebody 10 and its forward end portion offset downwardly, as at 109 and secured, as by the rivet 110 in facing engagement with the upper surface of the diaphragm 75. The rearward end portion 111 of the diaphragm arm 108 extends below and in generally tangential, contacting relation with respect to the radially toothed rotary member 102. That is, the rearward portion of the diaphragm arm is resiliently urged into tangential contact with the toothed member 102; and, the rearward terminal portion 112 of the diaphragm arm is angulated downwards away from the toothed member.

Obviously, when the inertia unit is energized, as described hereinbefore, successive teeth of the spur gear 102 will move into contact with the rearward end portion 111 of the diaphragm arm and repeatedly deflect the latter downwards. As the teeth of the gear 102 are relatively close together, and as the arm 103 is disposed generally tangent` to the latter gear, a somewhat sinusoidal oscillation will be imparted to the arm, rather than a ratchet type motion. This oscillation is transferred through the arm to the diaphragm 75, causing the latter to oscillate and produce sound in accordance with the frequency of oscillation. As the diaphragm plate 73 is arranged in spaced relation within the vehicle body 141, being spaced from both the upper and lower body shells, sound waves will be produced on both the upper and lower sides of the diaphragm. The sound waves produced on the underside of the diaphragm will pass directly through the apertures 61 to the surrounding medium Sound waves produced on the upper side of the diaphragm will also pass exteriorly of the yehicle body as the diaphragm plate 73 is spaced from the lower body sheil 20 and permits the passage of sound waves around the diaphragm plate, between the supporting pins 58 and 59, and thence outwards through the apertures 61. By thisvconstruction, a relatively high volume of sound is produced which accurately simulates that of actual jet vehicles.

The launching structure 11 includes a longitudinally extending base plate or runway 114 adapted torest upon an appropriate `supporting surface, and having its opposite longitudinal` side portions provided with parallel spaced guide members or rails, as defined by the upturned margins 115. Adjacent to the rear end of base or runway 114 is tixedly secured an upstanding, forwardly opening hood 116, which has its rearward end closed 'by a wall 117 extending` upwards` from the base 114.

Disposed within the hood 116, xedly secured to the rear hood wall 117, is a housing 118 having a front wall 119 spaced forwardly of the rear hood wall.

As best seen in Fig. 3, a shaft 121 extendsl longitudinally of the runway 11d and is rotatably supported in the front wall 119 of the housing 118 and the rear hood wall 117. A relatively large gear is xedly circumposed about the shaft 121, interiorly of the housing 118, and includes a rearwardly enlarged hub 123 engageable with the rear hood' wall 117 to prevent. rearward withdrawal of the shaft 121 from the hood. A. plurality'of protuberances 124 are formed on the shaft 121 interiorly ofthe housing 113, adjacent to the housing front wall 119 to prevent forward shifting movement of the latter shaft. Rearwards of the rear hood wall 117', the shaft 121 is provided with a crank extension 125' for manual cranking actuation to rotate the shaft 121 and gear 122'.'

A second longitudinally extending shaft 127, disposed below and in parallel spaced relation with respect to the shaft 121, is rotatably supported in the rear hood wall 117 and front wall 119 of the housing 118. Fixedly circurnposed about the shaft 12'7, in meshing engagement with the gear 122, is a spur gear or pinion 123 disposed adjacent to the rear hoodwall 117. An enlarged shoulder or collar 129 is provided on the shaft 127 interiorly of and adjacent to the housing front wall 119, so that the pinion gear and collar 1219 limit longitudinal shifting of the shaft 127 in both directions. The shaft 127 is formed with a longitudinal extension, shank or turning member 130 projecting forwardly substantially beyond the front wall of the housing118, and having its forward end headed, or otherwise enlarged, as by protuberances 131. Rotatably circumposed about the forwardly extending shank 1.10 of the shaft 127 is a helical coil spring 132 which has its rearward end in abutting engagement with the housing front wall 119. A retaining plate or bearing washer 133 is rotatably circumposed about the shank 130, interposed between and in engagement with the forward end of the spring 132 and headed end 131 of the shank. r1`hat is, the headed shank end `131 holds the washer 133 on the shank, and the washer retains th-e spring132 on the shank and under compression.

Actuation of the crank arm 125 causes the spur gear 122 to rotate, which in turn drives the pinion 128 and rotates the shaft 127 and shank 130.

A holding strip or catch member 13o, fabricated of resilient strip material, has oneend portion `137 disposed generally vertically and secured interiorly of the` housing 113, as by a fastener 133, in facing engagement with the rear hood wall 117. 1f desired, the rearward strip portion 138 may extend between the pinion 128 and the rear hood wall to further limit longitudinal shifting of the shaft 127. From the rearward strip portion 137, the catch member extends generally horizontally forwards through an opening 139 in the front wall of the housing 118, and terminates in a downwardly angulated free forward end 140 disposed forwardly of the headed shank end 131. Adjacent to the downwardly angulated terminal strip portion, the strip is formed with `a through aperture 16.11. By reason of its horizontal disposition, resilience, and the size of the opening 139, the catch or strip 136 is readily depressed or deiiected below its` normal position, which is the position illustrated in Fig. 3 in abutting engagement with the upper edge of the opening 139.

For convenience in depressing the strip 136, an upwardly angulated actuating member or rod 144 has `its lower end engageable with the upper surface of the strip interiorly of the housing 118, and extends upwards therefrom, terminating at its upper end in an enlarged head or button 1115 projecting outwards through the hood 116. That is, an apertured ear 146 slidably supports theA lower portion of the rod 144, and the button 14S is slidably 15 supported in the hood 116, so that depression of the button serves to depress the resilient strip or catch member below its normal position.

Fixed on the runway 114, forwardly of the hood 116, are a pair of laterally spaced, rearwardly converging, upstanding guide members or rails, 149, 149 which have their rearward end portions spaced apart laterally a distance just slightly greater than the combined widths of the spaced shoes or depressed under portions 63, 66 of the vehiclev body. Extending laterally between the guide members or rails 149 and 149, adjacent to the reaiyvard ends thereof, is a generally horizontally disposed shaft 150. The shaft has its opposite ends preferably rotatably supported in the respective guide members 149, 149 and is provided with a tubular spacing member or roller ,151'circumposed about the shaft intermediate the guide Vtween the forward portions of the guide rails 149 and 149, which serve upon further rearward movement to hold the vehicle in the proper lateral position. That is, the guide rails converge to properly position the shoes 68, 68 and hence the vehicle 1G. When the inclined rear shoe surfaces 69, 69 engage the roller 151, the latter serves to elevate the rear of the vehicle to raise the rear wheels 16, 16 above the runway. Simultaneously, the

depending end of the pin 70 engages with the forward terminal portion 140 of the resilient catch member 136 to deflect the latter downwards and permit continued riding up of the pin on the catch member until the pin snaps into the catch member opening 141, which position is illustrated in Fig. 3.

When the rear of the vehicle is elevated by the roller 151, the socket 106 will be disposed in substantial align ment with shank 130, and the plate or washer 133 in bearing engagement with the rear wall section 26 of the vehicle body. Hence, further rearward movement of the vehicle serves to displace the washer rearwardly to compress the spring 132, and displace the socket 106 rearn wardly to frictionally and non-rotatably receive the enlarged forward end 131 of the shank 131i. At this instant, the pin 70 snaps into the catch opening 141 and the vehicle may be released with the catch member 13d serving to hold the vehicle in the elevated launching posi- .tion of Fig. 3 against the force of the compressed spring Manual cranking of the arm 12S effects rotation of the shank 130, and the spring 132 and washer 133 remain unmoved. The non-rotative coupling engagement between the headed shank end 131 and socket 1416 serves to turn the latter and energize the wheels 16, 16, fly wheel 99, and diaphragm '75', all as `described hereinbefore.

vWhen substantial energy has been stored in the y wheel,

and other rotating parts, as by attaining a desired angular jvelocity, the button 1455 on the operating rod 144 may air, and subsequently engaging with the ground or other supporting surface when the vehicle has acquired substantial momentum. Hence, the energy of the fly wheel is not dissipated in starting friction, as when an inertia `motor vehicle is merely placed upon a supporting surface in the conventional manner, but rather, fully utilizes the stored energy to sustain forward movement of the vehicle.

From the foregoing, it is seen that the present invention provides a toy vehicle construction which fully accomplishes its intended objects, and well adapted to meet practical conditions of manufacture and use.
