RACING TOY HAVING VEHICLE-PROPELLING MEANS This application is a division of copending application Ser. No. 872,655, filed Oct. 30, 1969, now US, Pat. No. 3,545,757.

This invention relates to racing toys of the type in which vehicles move around one or more continuous tracks. A toy of this type is illustrated and described in copending application Ser. No. 802,365, filed Feb. 26, 1969, now US. Pat. No. 3,514,108.

The toy of the above-identified patent is of the particular type in which a vehicle can be caused to move along its track through successive unbroken cycles or laps. The arrangement illustrated in said patent includes a vehicle driving member or carriage slidable beneath a propulsion region of each track, shown as an uphill track portion. The carriage carries a projection extending upwardly through a slot in the track portion for engaging a depending part of a vehicle, whereby forward movement of the carriage causes forward movement of the vehicle. A handle manually manipulatable by a player is furnished, the handle being connected to the carriage so that movement of the handle is transmitted to the carriage, such movement serving to propel a vehicle along the uphill track portion. Once the vehicle reaches the top of the hill it is released, whereupon it moves around the track by gravity to the bottom of the uphill portion and, as a result of inertia, part of the way up the uphill portion.

If the player is skillful, he moves his handle at a time such that the projection carried by his carriage engages the depending part of his vehicle while the latter is still moving along the propulsion region due to inertia. In this way, further propulsion is given the vehicle with a minimum amount of lost vehicle speed.

It has been found that when the carriage projection and depending vehicle part are straight or flat, the projection has a tendency to slide past the depending part and hence not propel the vehicle. This is especially true when the carriage is moved very rapidly.

It is an object of the present invention to provide a racing toy of the type described wherein the projecting carriage element engages an extension depending from a toy vehicle in a secure manner so that there is no chance of the two slipping past each other, and hence there is assurance that each time the moving carriage element engages the depending vehicle extension the vehicle will be propelled forwardly.

Additional features and advantages of the invention will be apparent from the following description in which reference is made to the accompanying drawings.

In the drawings:

FIG. 1 is a perspective view of a racing toy according to the present invention;

FIG. 2 is a bottom view of the toy base;

FIG. 3 is an enlarged fragmentary top view of the rearward ponion of the propulsion region of the tracks, showing a partially broken-away toy vehicle on one of the tracks;

FIG. 4 is a vertical cross-sectional view taken on line 44 of FIG. 3;

FIG. 5 is a view similar to FIG. 4 showing the vehicle about to be engaged by the driving member;

FIG. 6 is a vertical cross-sectional view taken on line 6-6 of FIG. 3;

The racing toy chosen to illustrate the present invention comprises two side-by-side tracks 10 and 11 of generally elliptical contour. Although two tracks are shown in the present example, only one or as many side-by-side tracks as desired may be used. The tracks may be formed of a molded plastic material, and may be provided in sections adapted to be snapped together to form the continuous tracks. As shown in FIG. 6, the two track regions of each section may be formed integrally, with an integral upstanding divider I2 separating the two tracks. The tracks are also provided with outerupstanding walls 13 to prevent the vehicles from rolling off the tracks.

Thetracks 10 and 11 are generally flat and horizontal, except at theircurved end regions 14 which are raised to create inclined banks. The bankedregions 14 are supported by stanchions l5 and the straight track portions are raised slightly above their support surface byskirts 9 depending from the outer side edges oftracks 10 and 11. At the center of one of the straight runs of thetracks 10 and 11 the latter are joined to ahousing 16 enclosing the mechanism for propelling vehicles along the tracks. Thus, theportion 21 oftracks 10 and 11, to which thehousing 16 is connected, is termed the propulsion region of the tracks, since it is when the vehicles are in this region that a forward propulsion force can be applied to them by means of the mechanism inhousing 16.

When the toy is in use, each player controls a mechanism for propelling his vehicle along thepropulsion region 21 of its respective track. The vehicle then rolls by inertia around its track, in a counterclockwise direction in FIG. 1, until it reaches thepropulsion region 21, at which point the player again propels his vehicle along the propulsion region. The player whose vehicle completes a predetennined number of laps or cycles around the track first is the winner, and the winner will ordinarily be the player most proficient at operating his vehicle-propelling mechanism. It may be mentioned that sincetrack 10 is outside oftrack 11, in the present example the two tracks are not of equal length. Hence, the player whose vehicle usestrack 10 need complete fewer laps than the other player in order to cover the same total distance. If desired, the tracks could be furnished with two crossovers to equalize the lengths of the two tracks.

In the present embodiment, thehousing 16 contains two vehicle-propelling mechanisms, one being operated by thehandle 17 and the other by thehandle 18.Handle 17 is actuated to propel avehicle 19, illustrated as a toy automobile, along the propulsion region oftrack 10, andhandle 18 is actuated to propel anothertoy automobile 20 along the propulsion region oftrack 11. Eachhandle 17 and 18 is slidably accommodated within astraight slot 23 formed in the top wall (see also FIG. 2) of thehousing 16, these slots serving to guide the movements of the handles when the latter are actuated. The floor 25 (FIG. 6) of thepropulsion region 21 of each track is formed with a centrallongitudinal slot 26, and a pawl projects upwardly through each slot. As eachhandle 17 or 18 is shifted from its leftwardmost position in FIG. I to its rightwardmost position, thepawl 27 or 28, respectively, (FIGS. 2-6) associated with it moves from the left end of itsrespective slot 26, as viewed in FIGS. 1 and 3-5, to the right end. Each vehicle l9 and 20 is provided with a depending lip or extension 29 (FIGS. 4 and 5) adapted to be engaged by one of the pawls.

Thus, when thevehicle 19, for example, arrives at the left end of thepropulsion region 21 oftrack 10, the appropriate player shifts handle 17 to the right so that thepawl 27 engages the dependinglip 29 of the vehicle and propels it toward the right. Thereafter, the player moves thehandle 17 back toward the left, returning thepawl 27 to the left end of the track propulsion region in preparation for again propelling thevehicle 19 for further counterclockwise movement around the track. To a great extent, the skill required in playing with the present toy involves the ability to actuate thehandle 17 or 18 at precisely the right time so that the respective pawl smoothly engages the lip of the moving vehicle as the latter enters thepropulsion region 21. In this way, full advantage is taken of the initial movement of the vehicle into the propulsion region due to its inertia.

The mechanisms for transmitting movements of thehandles 17 and 18 to theirrespective pawls 27 and 28 are illustrated in detail in FIGS. 2-6. The two mechanisms are almost identical, and therefore except for the points at which they differ only one will be described. However, corresponding parts of the mechanism bear identical reference numerals followed by a prime. Mounted on the lower face of each track propulsion region is a guideway 32 (FIGS. 4-6) defined by twoparallel walls 33, which may be integrally formed with thetrack floor 25.Walls 33 rest on, and are secured to, as by cement, abottom wall 34 which may be integral with thetop wall 24 of thehousing 16. Formed inbottom wall 34, directly beneath and parallel toslots 26, are a pair ofslots 35. Theguideway 32 extends for substantially the full length of the propulsion region. Slidably arranged within theguideway 32 is a vehicle driving member orcarriage 36 carrying near its rear end a transverse pin 37 (FIGS. 4 and 5) upon which pawl 27 or 28 in pivotally supported. A coiled spring 39 (FIG. 4) surroundspin 37, one end of the spring being fixed with respect tocarriage 36, and the other end of the spring being secured to thepawl 27. Thespring 39 normally holds thepawl 27 against anabutment portion 40 of thecarriage 36 so that the pawl cannot rotate in a counterclockwise direction when in the solid line position shown in FIG. 4. Consequently, when thecarriage 36 is moved along theguideway 32, this movement is transmitted to thelip 29 ofvehicle 19 or 20 by the pawl. However, the pawl can rotate clockwise, against the force ofspring 39, so that whenvehicle 19 or 20 enters thetrack propulsion region 21,lip 29 can move past the pawl. In other words, when vehicle I9 is moving from the left toward the right, and the front face of itslip 29 strikes the rear inclined face ofpawl 27 rotating it clockwise, the upper end of the pawl moves toward theslot 26, as shown in broken lines in FIG. 4, permitting the vehicle to pass. The pawl is then immediately snapped into a position for engaging the rear face of thelip 29 by thespring 39.

Pawl 27 and 28, includes afinger 30 projecting forwardly, i.e., in the direction of movement of a vehicle along its track, from the top of the pawl.Lip 29 is formed, at its lower end, with aledge 31 projecting rearwardly, i.e., in the direction opposite to the direction of vehicle movement. When pawl 27 moves into engagement withlip 29, as shown in broken lines in FIG. 5,finger 30 moves to a position aboveledge 31, temporarily interlocking the pawl and lip and preventing relative vertical movement between the two, i.e., preventing movement ofvehicle 19 away from the track. As a result, there is no chance ofpawl 27 slippingpast lip 29 even ifcarriage 36 carrying the pawl is moved forwardly very rapidly by a player.

Thecarriage 36 carries a dependingpin 43 extending throughslot 35 to which one end of a lever 44 (FIG. 2) is pivotally connected. Lever 44 comprises two telescoping parts, namely, an outer member 45 and aninner member 46 slidably arranged within member 45. It is the free end ofextension 46 which is pivotally connected to thecarriage 36. The opposite end of the member 45 is pivotally supported on a pin 48 carried by a bracket 47 secured to the under face oftop wall 24. Beneath bracket 47 is a horizontal plate 50, also mounted on the under face oftop wall 24 by elongated pins 51, which supports another bracket 47' carrying pine 48. It will be seen that since brackets 47 and 47' are located in different horizontal planes, levers 44 and 44' are allowed to swing, about pins 48 and 48', in difierent horizontal planes without interfering with each other. Since the distance between the pin 48 and theguideway 32, as viewed in FIG. 2, depends upon the angle of the line drawn between them, the sliding relationship between themembers 45 and 46 permits the effective length of the lever 44 to be varied as the lever pivots about the pin 48.

Alink 52 pivotally connects thehandle 17 to lever member 45 and serves to transmit horizontal shifting movement of the handle along itsslot 23 to the member 45. Lever 44 is thereby caused to rotate about pin 48, and viaconnection 43move carriage 36 along itsguideway 32. The arrangement is such that handles 17 and 18 may be moved horizontally, along theirrespective slots 23, through precisely the same distance, and levers 44 and 44' swing about their pivot axes through exactly the same length arcs, since the horizontal spacing between pins 48 and 48' is equal to the horizontal spacing between theslots 26 in tracks and 11. Consequently, neither player is given any mechanical advantage which the other player does not also enjoy.

The invention has been shown and described in preferred form only, and by way of example, and many variations may be made in the invention which will still be comprised within its spirit. It is understood, therefore, that the invention is not limited to any specific form or embodiment except insofar as such limitations are included in the appended claims.
