Abstract

A toy 10 is composed of a first vehicle 12 and a second (satellite) vehicle 14 connected by a cord 16. The first vehicle 12 has driven wheels 18, the wheels of the second vehicle are free-wheeling. Pulling the second vehicle 14 away from the first vehicle 12 extends the cord 16 and activates a motor in the first vehicle 12. On releasing the vehicles the activated motor drives the first vehicle 12 at a first velocity and winds up the cord 16 to pull the second vehicle 14 towards the first vehicle 12 at a velocity greater than the first velocity. Accordingly, the second vehicle 14 eventually catches up with the first vehicle 12 and is drawn up onto the body 22 of the vehicle 10 via the lowered tail gate 24. This action trips a mechanism in the first vehicle 12 which lifts the tail gate 24 and alters the gearing between the motor and the driven wheels 18 so that the now loaded vehicle 12 proceeds at a second velocity greater than the first velocity until the motor is deenergized. <IMAGE>

Description

SPECIFICATION Variable speed vehicle with satellite vehicle BACKGROUND OF THE INVENTION This invention is directed to a toy having a primary vehicle and a satellite attached thereto which can be extended from the primary vehicle and which, in so doing, activates a motor in the primary vehicle which returns the satellite to the primary vehicle. The activated motor drives the primary vehicle at a first velocity when the satellite is extended away from the primary vehicle and at a second velocity when the satellite has been returned to the primary vehicle.

A class of toys exist which are exemplified by U.S. patents 2,795,081; 4,114,310; 4,068,401 and 2,803,921. This class of toys is directed to toys which have a main component part and at least one auxiliary, or satellite, component part attached thereto by a tether, string, or the like. Additionally, U.S.

3,688,435 describes a hand-holdable device wherein a satellite object is made to extend from and return to the device by manipulation of certain components parts of the device.

While the device of the patent listed in the previous sentence is related to this invention, the devices described in the other patents previously listed are more closely related.

In U.S. 2,795,081, a mother duck is pulled by a string. Connecting to the mother duck is a tether which includes two ducklings attached thereto. As the mother duck is pulled along, the tether attached to the ducklings is first retracted into the mother duck, bringing the ducklings closer to the mother duck, and then allowed to extend out of the mother duck, allowing the ducklings to fall farther behind the mother duck.This is accomplished by having a belt drive connecting between a set of front and back wheels in the mother duck with a portion of the belt drive being thicker than the remaining portion such that the thicker portion contacts a spindle to wind the ducklings toward the mother duck during one half of the rotation of the belt, and then disengages with the spindle for the remainder of the rotation of the belt, at which time the spindle is no longer rotated within the mother duck, allowing the tether to be extracted by the mass of the ducklings pulling on it.

U.S. 2,803,921 describes a toy which also has an auxiliary body attached to a driving body. Located within the driving body is a spool to which the tether is attached. As the driving body moves forward, the spool is wound, bringing the auxiliary body in contact with the driving body. The auxiliary body has the capacity to open up, giving the impression of swallowing the driving body. When the driving body becomes located within the interior of the auxiliary body, winding of the tether on the spool ceases, and movement of the driving body ceases. Since the driving body has become located within the auxiliary body and is no longer in contact with the support surface, the toy ceases all movement with respect to the driving surface as soon as the driving body becomes located within the auxiliary body.

U.S. 4,068,401 utilizes a principle very similar to U.S. 2,803,921. The difference between these two patents is that U.S.

4,068,401 is directed to an aquatic vehicle, which, instead of being propelled along a support surface by driving wheels and the like, utilizes appropriate movement of a pivotable tail, pivotable paddles, or the like, to propel the driving body in an aquatic environment. A further difference between this patent and U.S. 2,803,921 is that it is the body capable of containing the other body that has the driving means located therein. U.S.

4,068,401 has in common with U.S.

2,083,921 the fact that once the one body is located in the other body, all movement of both bodies ceases and the toy remains static.

U.S. 4,114,310 is closely related to the patents mentioned above. It differs from U.S.

4,068,401 in that it is a land vehicle capable of moving over a solid support surface by driving wheels and the like. As with the patents mentioned in the previous paragraph, one of the two bodies of this patent is capable of containing the other of the bodies. This patent contains a feature extracted from both of the patents noted in the previous paragraphs in that, in one embodiment, it is the driven member which ultimately contains the driving member in its interior, and in another embodiment it is the driving member that ultimately contains the driven member in its interior. As with the devices mentioned in the previous paragraph, once one of the members is located in the other of the members, all movement of both members ceases and the toy remains static.

While it is considered that the toys noted in the above noted patents all have considerable play value, as was pointed out with regard to U.S. 4,114,310, U.S. 4,068,401 and U.S.

2,803,921, once one of the bodies has become located in the other of the bodies, action of the toys described therein ceases, and the toy remains static and inanimate. It is considered that while all of the toys of the above noted patents have a compelling feature in that one body moves with respect to another body, there exists a need for a toy which includes this feature, but also includes an additional feature wherein the toy does not remain static and inanimate after association of the two bodies, but continues in an action mode.

BRIEF DESCRIPTION OF THE INVENTION Accordingly, in its broadest aspect, this invention provides a toy which has a main, or primary body and an auxiliary body connected thereto, with the feature that movement of the auxiliary body away from the primary body activates the toy, and once so activated, the auxiliary body becomes reassociated with the primary body, and after reassociation, both bodies maintain some mode of action for a subsequent period of time.

All will become evident from the remainder of this specification these features may be achieved in a toy which comprises: a first body; said first body including a spring activated motor means; said first body including a variable velocity moving means operatively associated with and receiving power from said motor means and capable of moving said first body at at least two velocities with respect to the support medium; a second body associated with said first body; a connecting means fixedly attached to said second body and movably associated with said first body motor means whereby movement of said second body away from said first body from a proximal position to a distal position moves said connecting means with respect to said motor means activating said motor means, and when so activated said motor means interacting with said connecting means by moving said connecting means and in response to said movement of said connecting means said second body being moved from said distal position towards said first body to said proximal position; velocity governing means operatively associated with said moving means and operatively responsive to the position of said second body with respect to said first body whereby after said second body has been moved from said proximal position away from said first body to said distal position said moving means in association with said governing means moving said first body at one of said velocities and when said second body is moved from said distal position towards said first body to said proximal position in response to interaction of said motor means with said connecting means said moving means in association with said governing means moving said first body at a second velocity.

In the illustrative embodiment of the invention herein; when said second body is in said proximal position, said first body would be capable of holding said second body and transporting said second body in conjunction with said first body with respect to the support medium.

In the preferred embodiment of the invention, the moving means would further include a fly wheel means capable of being energized as the first body moves at one of the velocities, and when so energized, would be capable of moving the first body at a second velocity including transporting the second body by the first body at said second velocity.

The velocitv aovernina means would Dreferredly include a second body sensing means located on the first body and capable of sensing when the second body is in the distal position and when it is in the proximal position.

Preferredly, the first body would comprise a first vehicle and would include at least one drive wheel located on this vehicle. The moving means would preferredly comprise a gear train means associated with the drive wheel, the motor means and the fly wheel means.

The gear train means would be capable of propagating power from the motor to both the drive wheel and the fly wheel means in a first instance to move the vehicle at a first velocity and to concurrently energize the fly wheel means, and in a second instance, capable of transmitting power stored in the fly wheel to the drive wheel to move the vehicle at a second velocity. In this preferred embodiment, the connecting means would include a flexible connecting member connecting between the motor means and the second body, with the motor means interacting with this flexible connecting member by accumulating the same within the first vehicle.

Preferredly, the velocity governing means would further include a gear train shifting means operatively associated with the second body sensing means and the gear train means. The gear train means would include at least two gear pathways connected to and rotating the drive wheel. One of the pathways would connect the motor means to both the drive wheel and the fly wheel means and the other of the pathways would connect the fly wheel means to the drive wheel. The gear train shifting means would connect one of these pathways and disconnect the other in a first instance when the second body sensing means senses that the second body is in the distal position and would reverse the connection when the sensing means senses that the second body was in the proximal position.

For this reason this invention is not to be construed as being limited to the illustrative embodiment herein, but is to be construed as only being limted by the claims appended hereto.

DETAILED DESCRIPTION OF THE INVEN TION Prior to describing the mechanical components constituting the illustrative embodiment of this invention, a brief description of the operation of the invention will facilitate further understanding of the mechanical components utilized therein. In Fig. 1, a toy 10 is composed of a first vehicle 12, a second vehicle 14 and a connecting cord 16. The first vehicle 1 2 includes a set of front driving wheels, collectively identified by the numeral 18, a set of free-wheeling rear wheels, collectively identified by the numeral 20, a truck body, identified by the numeral 22 and a tail gate identified by the numeral 24.The second vehicle 1 4 is shaped as a motorcycle and, for the illustrative embodiment of the toy 10 utilized for the purposes of this specification, is simply formed as a molded body, including wheels, rider and the like (not seperately identified or numbered). The molded parts of the second body 1 4 are totally non-functional and are for visual purposes only. The second vehicle 14 is of relative little weight, and as such is simply slid along a support surface as herein identified, without the utilization of rotatable wheels and the like. Other embodiments than that illustrative embodiment shown herein could, of course, utilize rotating wheels on the second body 1 4 if desired.

To operate the toy 10, the person operating the toy simply grasps the first vehicle 1 2 in one hand, the second vehicle 1 4 in the other hand, and seperates the second vehicle 14 from the first vehicle 1 2 by pulling the second vehicle 1 4 away from the first vehicle 1 2.

This elongates the cord 1 6 and places the second vehicle 14 in a position which is distal to the first vehicle 12, such as is seen in Fig.

1. In so moving the second vehicle 14 away from the first vehicle 1 2 and elongating the cord 16, a motor as herein identified and described is activated. Upon releasing of both the first and second vehicles 1 2 and 14, the activated motor causes the first vehicle 1 2 to be propelled across a support surface at a first velocity.Concurrently, the first vehicle 1 2 pulls the second vehicle 1 4 via the cord 1 6 along with it, and simultaneously, the cord 1 6 is wound up, or drawn back into, the first vehicle 12, which pulls the second vehicle 14 at a greater velocity than the first vehicle 12, such that the second vehicle 1 4 overcomes the first vehicle 1 2.

As the second vehicle 1 4 overcomes the first vehicle 12, it approaches the first vehicle 12, and as seen in Fig. 2, is pulled up on the tail gate 24 of the first vehicle 1 2 and then into the bed of the body 22 of the first vehicle 12.

When the second vehicle 1 4 is in a position proximal to the first vehicle 12, and in fact is within the confines of the body 22, the second vehicle 1 4 trips a mechanism, as hereinafter described, which results in lifting of the tail gate 24 into the position seen in Fig. 3 and a change in the velocity in the first vehicle 1 2 from that of its originai slower velocity to a faster velocity. The first vehicle 12, with the second vehicle 1 4 located thereon, now proceeds across the support surface at this higher velocity until the driving mechanism, as hereinafter illustrated and explained, within the first vehicle 1 2 is de-energized and the totality of the toy 10 comes to rest.The toy 10 is now ready to repeat the cycle by once again withdrawing the second vehicle 14 from the first vehicle 1 2 and energizing the toy 10.

Referring now to Figs. 4 through 10 of the drawings, the internal components of the first vehicle 1 2 are illustrated. Fig. 6 shows the arrangement wherein the second vehicle 1 4 is located on the first vehicle 1 2 and is being carried by it. Fig. 7 illustrates certain components as they are while the second vehicle 1 4 is being pulled away from the first vehicle 1 2 to activate the toy 10. Fig. 8 shows these same components after the second vehicle 14 has been released and is being drawing back to the first vehicle 1 2. Fig. 5 is a view of the other side of Figs. 6, 7 and 8, showing how certain gears, later identified, intermesh and the like.

The power and control unit 26 fits within the first vehicle 1 2 as is indicated by the dotted lines in Fig. 1. This unit 26 has two side housing components 28 and 30, and a bottom housing component 32. Additionally, there is a central housing component 34 located about midway between the two side components 28 and 30, and a plurality of cross members, collectively identified by the numeral 36, which, in conjunction with the bottom housing 32, maintain the side components in their respective position and fixedly hold the power and control unit as a unit. The unit 26 is appropriately mounted by screws and the like to the body 22 of the first vehicle 12.

The side housings 28 and 30, as well as the central housing 34, contain a plurality of drillings and hollow bosses, not identified or numbered, which serve as bearing surfaces for appropriate axles and the like, as herein identified. Mounting of the individual axles and the like will therefore not be discussed in great detail.

An axle 38 is appropriately supported in housings 28 and 34. A large circular boss 40 is formed on the inside surface of the side housing 28. The boss 40 is hollow and is open on the side toward the central housing 34. Mounted next to the boss 40 about axle 38 is a spool 42. One of the edges of the spool 42 is formed as a gear 44. The other of the edges is formed as a flange 46. The gear 44 and flange 46 serve as edges such that the cord 1 6 can be wound about the spool 42.

One end of the cord 1 6 is fixedly attached to the second vehicle 14 and the other end is fixedly attached to the spool 42. As such, movement of the cord 1 6 is transferred into rotation of the spool 42 and vice versa.

Coiled inside of the boss 40 is a flat coil spring 48. One end of the spring 48 passes around two bosses 50, which are formed on the outside of the flange 46 and project inwardly within the interior of the boss 40.

The other end of the spring 48 is hooked to a cross member 52 projecting between side housing 28 and central housing 34. The attachment to cross member 52 anchors one end of the coil spring 48 to the power and control unit 26, while winding of the other end of the spring 48 about the bosses 50 attach the other end of the spring 48 to the spool 42. The spring 48 is wound about within the interior of the boss 50 and the cord 1 6 is attached to the spool 42 such that movement of the cord 1 6 in a direction away from the power and control unit 26 causes clockwise rotation of the spool 42, as viewed in Figs. 6, 7 and 8, which in turn causes or creates a bias in the spring 48.Once the cord 1 6 is totally withdrawn from the power and control unit 26, with the second vehicle 1 4 located in a distal position with respect to the first vehicle 12, the spring 48 is at its maximum tension. By releasing the second vehicle 14, which in turn releases the cord 1 6, the tension within the spring 48 then rewinds the cord 1 6 on the spool 42, rotating the spool 42 counterclockwise, as viewed in Figs. 6, 7 and 8.

An axle 54 serves as the front axle for the first vehicle 1 2. The drive wheels 1 8 are fixedly mounted to the axle 54 and thus the axle 54 and the drive wheels 1 6 rotate in unison.

A bushing 56, having a convoluted surface on one of its ends, is fixedly mounted to axle 54 near side housing 28. A similar bushing 58 is fixed to axle 54 near side housing 30. A gear 60, having a bushing 62 located on its side, is freely located about axle 54. The bushing 62 interacts with the bushing 56 to form a clutch mechanism between gear 60 and the axle 54. A second gear, pinion gear 64, having a bushing 66 located on its side, likewise is free-wheeling about axle 54, but in combination with the bushing 58, the bushing 66 serves as a clutch mechanism to communicate rotation of the pinion 64 to the axle 54.A spring 68 passes through an appropriate opening in the central housing 34, allowing the spring 68 to push against both the gear 60 and the pinion 54, which in turn pushes the bushing 66 against the bushing 58 and the bushing 62 against the bushing 56 to complete the two clutch mechanisms.

The pinion 64 will slip with respect to the axle 54 by compression of the spring 48 toward the gear 60 and the gear 60 will slip with respect to the axle 54 by compression of the spring 48 toward the pinion 64.

An axle 69 is appropriately mounted in two slots, one of which is located in the side housing 28 and the other in the central housing 34. The one of these slots 70 formed in the side housing 28 can be seen in Fig. 6.

The other of the slots is not shown in the Fig., however, it would be identical to the slot 70 seen in the housing 28 but would simply be located in the central housing 34. In any event, axle 69 is free to move up and down in these slots. Axle 69 carriers a compound gear thereon which includes a pinion 72 and a spur gear 74. The pinion 72 can mesh with gear 60, which, it will be remembered, was mounted about axle 54, and the spur gear 74 can mesh with the gear 44 on the spool 42.

If the gear 44 on the spool 42 is rotating counterclockwise, as seen in Figs. 6, 7 and 8, the counterclockwise rotation of the gear 44 causes the gear 44 to mesh with the spur gear 74, depressing the axle 69 downward in the slots 70 such that the pinion 72 meshes with the gear 60. Thus, upon counterclockwise rotation of the gear 44 under the influence of the bias in spring 48 when it is wound tight results in clockwise rotation of both the pinion 72 and the spur gear 74 which are attached together, and counterclockwise rotation of the gear 60, which in turn, rotates the axle 54 counterclockwise, and the drive wheels 1 8 counterclockwise.

This will propel the toy 10 in a direction toward the left as viewed in Figs. 6, 7 and 8.

When the gear 44 is rotated clockwise as viewed in Figs. 6, 7 and 8 however, the clockwise rotation of the gear 44 tends to lift the pinion 72 and spurt gear 74 upwardly, such that their axle 69 rides up in the slots 70, which breaks the contact between the pinion 72 and the gear 60 and thus the clockwise rotation of the gear 44 is not communicated to the gear 60.

If the gear 44 is fixedly held as hereinafter described, but the drive wheel 1 8 is being rotated counterclockwise as seen in Fig. 7, as for instance, if the child utilizing the toy 10 was simply pushing the toy 10 along a surface, the counterclockwise movement of the gear 60 with no accompanying counterclockwise movement of the gear 44, would cause the pinion 72 and spur gear 74 to lift their axle 69 up in the slots 70, breaking the connection between the pinion 72 and the gear 60, allowing for free-wheeling of the first vehicle 1 2 in a forward direction across a support surface.If the gear 44 is fixedly held as hereinafter explained, and the first vehicle 1 2 is moved backwards as viewed in Figs. 6, 7 and 8, such that the gear 60 would be turning clockwise, the pinion 72 and spur gear 74 would be forced into engagement with the respective gears 60 and 44, with the axle 69 found in the lower portion of the slot 70, and this would lock the gear 60. However, because of the clutch action between the bushings 56 and 62, the axle 54 would be allowed to slip with respect to the gear 60 by compression of the spring 48.

An axle 76 traverses between side-housing 30 and central housing 34. A pinion 78 is fixedly located on axle 76 in the area between the two housing members. A fly wheel 80 is also fixedly mounted to the axle 76. However, it is on the outside of the housing 30. Thus, both the fly wheel 80 and the pinion 78 rotate in conjunction with rotation of the axle 76.

An axle 82 traverses between the side housing 30 and the central housing 34. It carries on it a pinion 84 and a spur gear 86, both of which are fixed to the axle 82 and rotate in conjunction with it. The spur gear 86 meshes with the pinion 78, which, as noted above, is connected to the fly wheel 80.

An axle 88 extends between the side housing 30 and the central housing 34 and carries on it a pinion 90 and a spur gear 92. The spur gear 92 meshes with the pinion 84.

Thus there is a continuous drive train of gears between pinion 90 and the fly wheel 80.

An axle 94 is slidably mounted in all of the housing components 28, 30 and 34. The axle 94 carries a pinion 96 fixedly mounted to it.

In between the housing components 30 and 34, the axle 94 carries on it a spur gear 98, which is also fixed to the axle 94 and rotates in conjunction with it. Thus, spur gear 98 and pinion 96 rotate with respect to one another.

A spring 100 is positioned between spur gear 98 and housing component 30 which biases the spur gear 98 away from the housing component 30 towards the housing component 34, and in doing so, slides the axle 94 in a direction toward the housing component 28. The axle 94 also carries a bushing 102 fixedly located on it, which, when interacted upon as indicated below, in conjunction with the spring 100, serves to position the axle 94 and the components located thereon between a first position as seen in Fig. 9, and a second position as seen in Figs. 10 and 4.

When the axle 94 is in the first position, the pinion 96 meshes with the gear 60, and as such, the pinion 96, the axle 94 and the spur gear 98 located thereon, rotate in conjunction with rotation of the gear 60. Spur gear 98 is in continuous intermesh with pinion 90, and thus, when the axle 94 is in the first position, the rotation of the gear 60 is transferred through pinion 96, to spur gear 98 to pinion 90, which in turn, as pointed out above, ultimately transfers rotation to and rotates the fly wheel 80.

When the axle 94 is in the second position, the pinion 96 disengages with the spur gear 60 and the spur gear 98 engages with the pinion 64 located on the axle 54. In this configuration, energy stored in fly wheel 80, if the same is rotated, can be transferred via the pinion 90 to the spur gear 98 and from there to the pinion 64 to rotate the axle 54 and the drive wheel 1 8 attached thereto.

A plate 104 is hinged to the housing components 28 and 30 about an axle 106. The cord 1 6 passes through an opening in the plate 104. A ratchet 108 is hinged to central housing 34 via an axle 11 0. A hairpin spring 11 2 biases the ratchet 108 to the right in Figs. 6, 7 and 8, and to the left in Fig. 5. The bias imparted to the ratchet 108 in turn, by contact of the ratchet 108 against the extension 114 on the plate 104, biases the plate 104 counterclockwise about its axle 106 as seen in Figs. 5, 6 and 7, and clockwise as seen in Fig. 8.

A sliding member 11 6 is biased by a spring 11 8 backward towards the plate 1 04. The sliding member 11 6 includes a wedge-shaped surface 1 20 on it, which is positioned to interact with the bushing 102 on the axle 94.

The wedge-shaped surface 1 20 is located on the inside surface of the projection 1 22 of the sliding member 11 6. The projection 1 22 can be seen in Figs. 6, 7 and 8. The projection 1 22 forms the bottom half of the end of sliding member 11 6 with the top half (not seperately numbered or identified) located on the top of the axle 104. This "U" shape on the edge of the sliding member 11 6 keeps it centered about the axle 94.

When the second vehicle 1 4 is located in a position proximal to the power control unit 26 the front of second vehicle 1 4 contacts the plate 104 and pivots it inwardly toward the remainder of the components of the unit 26.

This causes the extension 114 to contact the ratchet 108, which moves the ratchet 108 in a clockwise direction as seen in Figs. 6, 7 and 8, such that the ratchet 108 engages the gear 44 on the spool 42 and fixedly holds the spool 42 against further rotation. Also at this time, the wedge-shaped surface 1 20 on the projection 1 22 engages the bushing 102 and slides the sliding axle 94 and pinion 96 and spur gear 98 located thereon to the second position seen in Figs. 10 and 4.When the second vehicle 14 is not in the proximal position, but is moved somewhere away from the power and control unit 26, the second vehicle 1 4 no longer engages the plate 104 and under the bias of both the spring 11 2 on the ratchet 108 and the spring 11 8 on the sliding member 116, the ratchet 108 rotates clockwise to disengage with the gear 44 and the sliding member 11 6 slides towards the rear of the power and control unit 26, allowing the bushing 102 to slide against the wedge-shaped surface 120, which in turn allows the axle 94 and the pinion 96 and spur gear 98 attached thereto to move to the first position as seen in Fig. 9.

In utilizing the toy 10, as noted earlier, the second vehicle 14 is first pulled away from the first vehicle 1 2. This is illustrated in Fig.

7. As this happens, the plate 104 rotates counterclockwise as seen in Fig. 7, allowing the ratchet 108 to disengage the gear 44 and plate 104 to slide backwardly, positioning the axle 94 and the components attached thereto in their first position as seen in Fig. 9.

When the second vehicle 14 is fully extended away from the first vehicle 1 2 with all of the cord 1 6 wound off of the spool 42, the components noted in the previous paragraph remain in the position as noted. However, at this time, the spring 48 has been fully wound and thus the vehicle 1 2 is energized. Further in reference to Fig. 7, it can be seen that the compound gear composed of the pinion 72 and the spur gear 74 has disengaged with the gear 60, such that during winding or tensing of the spring 48, no motion is communicated to the gear 60, which in turn results in no rotation of the axle 54, which subsequently in turn results in no rotation of any other of the gear train as previously described.

When the second vehicle 14 is in a distal position and the cord 1 6 has been fully extended, and the second vehicle 14 is released, the spring 48 causes winding of the spool 42 in a counterclockwise direction as viewed in Fig. 8, which accumulates the cord 1 6 about the spool 42. In so doing, the gear 44 is turned counterclockwise as viewed in Fig. 8 which causes engagement of the spur gear 74 against the gear 44 and engagement of the pinion 72 against the gear 60, causing rotation of the axle 54 which drives the first vehicle 1 2 forward at a first velocity and concurrently rotates the fly wheel 80, energizing the same.

When the cord 1 6 has been fully accumulated on to the spool 42, such that the second vehicle 1 4 is located on the first vehicle 1 2 and the second vehicle 14 engages the plate 104, the engagement of the second vehicle 1 4 against the plate 104 rotates the plate 104 counterclockwise as seen in Fig. 6, which in turn causes engagement of the ratchet 108 against the gear 44, locking the gear 44. Also, movement of the plate 104 counterclockwise causes engagement of the plate 104 against the sliding member 116, sliding the sliding member 11 6 forward, causing the wedge-shaped surface 1 20 to engage the bushing 102 to move the axle 94 to its second position shown in Figs. 9 and 4.As soon as the axle 94 is moved into its second position, pinion 96 disengages gear 60 and spur gear 98 engages pinion 64 as noted above, which allows for the energy stored in the fly wheel 80 to now be transferred to the axle 54 to continue rotating the drive wheels 1 8. However, because of the gearing, the rotation of the axle 54 is at a different speed under the influence of the fly wheel 80 than it was under the direct influence of the gear 44 and the first vehicle moves at a more rapid velocity across the support surface until all of the energy stored in the fly wheel 80 is lost and the toy 10 comes to rest.

The locking of the gear 44 by the ratchet 108 when the second vehicle engages the plate 104 ensures that the gear 44 is fixedly held, and thus, when the first vehicle 1 2 is moving forward under the energy stored in the fly wheel 80, the gear composed of the pinion 72 and the spur gear 74 moves upwardly and breaks the contact between the gear 60 and the gear 44, allowing for disengagement of the gear 44 from the drive train.

The clutches composed of the bushings 58 and 66 and 56 and 62 allow for rotation of the drive wheels 1 8 both backward and forward. This is designed to prevent damage to the toy 10 in instances where the toy 10 is pushed backwards by hand across a support surface with the gear 44 locked by the ratchet 108; where the user of the toy 10 inappropriately rotates the drive wheels 1 8 in one direction or the other, concurrently pulling the second vehicle 14 away from the first vehicle 12; where the fingers of the user of the toy 10 are held against the plate 104 causing the gear train to be shifted into the second position, or like events.

As seen in Fig. 6, the tail gate 24 is connected to the plate 104 via a member 1 24. The tail gate 24 is hinged to the body 22 via an axle 1 26 and the connection via the member 1 24 is such that the tail gate 24 moves in unison with the plate 104, the tail gate 24 being raised when the plate 104 is forward as it is when the second vehicle 14 is located against it, and being lowered when the plate 104 is moved rearwardly as it is when it is released by moving the second vehicle 14 backwardly from its proximal position to its distal position.

As will be appreciated from tha construction described herein, when the axle 94 is in the second position such that axle 54 is linked to the fly wheel 80, which of course occurs when the second vehicle 1 4 is located on the first vehicle 12, the toy 10 is capable of functioning as an inertia powered toy. The user of the toy 10 simply pushes the toy 10 across a support surface, which rotates the drive wheels 1 8 and transfers this rotation to the fly wheel 80 to energize the same. With the fly wheel 80 energized, the release of the toy 10 by the user is followed by movement of the toy 10 across a support surface under the energy stored in the fly wheel 80.
