SUMMARY OF Tl-E INVENI'ION
The present invention comprises a launching mechanism for a self-propelled toy vehicle, said launching mechanism being embodied, in -the preferred form of this invention, in a wrist~mounted housing.
Briefly stated, the launching mechanism of the present invention includes two keepers, one to engage a spring-urged dome and hold it in closed position against its spring action, and the other to engage a forwardly biased ~spring-urged) toy vehicle and hold it in stationary position against its spring bias. The keepers are themselves spring biased to hold them in engagment, respectively, with the dome and the toy vehicle.
A lost motion or -time delay element is provided in connection with the second keeper, whereby release of the toy vehicle is arranged to occur subsequent in time to the release of the dome. In one form of this invention, a cam linkage provides the lost motion or time delay feature.
In the operation of the launching mechanism herein described and claimed, the release of the toy vehicle does not automatically occur after release of the dome. Instead, release of the toy vehicle is controlled by the child operating the device; he may release the vehicle immediately following release of the dome or he may delay releasing the vehicle until such time as he may choose to do so.
An important feature of the present invention resides in the control it affords to a child. Specifically, the entire mechanism may be mounted on the wrist of one hand while the entire operation of the mechanism is conducted by the fingers of the other hand. I'he child may orient the mechanism and L3~
direct the toy vehicle by simply adjusting the position of the wrist on which the mechanis~ is mountecl. Gnce the device is properly oriented it may be operated without disturbing its orientation. By the same token, the device may be reactivated by simply replacing the toy vehicle in its housing and closing same. This again can be done with one hand while the device remains positioned on the wrist of the other hand.
In summary, the present invention provides a launching mechanism for power-driven toy vehicles, comprising: ~a) a housing structure adapted to house a power-driven toy vehicle, ~b) said housing structure having a base providing a supporting platform for the toy vehicle and a dome pro-viding an enclosure for the toy vehicle, ~c) said dome being pivotally mounted on the base and pivotally movable between closed and open positions, ~d) a spring operative between the dome and the base to urge the dome into open position, and ~e) a control member on said base having a first keeper element to engage and hold the dome in closed position and a second keeper element to engage and hold the toy vehicle in stationary position, (f) said control member being manually movable relative to the base to disengage the first keeper element from the dome and thereby to release the dome for spring-urged movement into open position, and to disengage the second keeper element from the toy vehicle and thereby to release the toy vehicle to be driven off the base.

DESCKIPTIO~ OF PREF~RRED FORM OF THIS INVENTION
Referring now to the details of the invention as illustrated in the drawing it will be understood that self-propelled toy vehicle 10 may be powered by any conventional means such as a sprlng motor or a battery operated motor.
In the preferred form of this invention the toy vehicle is spring-powered as described in Fig. 12 of the drawing.
Stem 12 is used to wind coil spring 14 which drives the vehicle through a gear train 16. It will be observed that winding stem 12 and more particularly its knob 12a projects outwardly from the housing of the device and this will enable the spring to be wound while the vehicle is enclosed within the housing. Alternatively, of course, the spring may be wound before the vehicle is placed within the housing.
The invention comprises the following elements: a base 18 adapted to be mounted on the wrist 20 of one hand, a strap 22 adapted to adjustably secure the base to the wrist, said base 18 including a platform 24 for the toy vehicle 10, a dome 26 which is adapted to function as an enclosure or housing for the toy vehicle, a ramp 28 for the toy vehicle, said ramp bein~ adapted to extend outwardly from the base when in operative position and being adapted for retraction into the base when inoperative, and a control member 30 which is provided with a pair of keepers 32 and 34 respectlvely, one to engage and hold the dome in closed position, and the other adapted to engage and hold the toy vehicle in stationary position.
It ~ill be observed, see Figs. 9 and 10, that dome 26 is provided at its back end with a pair of bushings or bearings 36 and 38 respectively which are rotatably mounted on a pair of stud shafts 40 and 42 respectively on base l~. This enables the dome to pivot between closed position (phantom lines) and ~3~
open position (solid lines) as illustrated in Fig. ~. A
torsion spring 44 on stud 46 interengages a projection 48 on the dome and a section 50 on the base to urge the dome into open position. See Fig. 10.
At its forward end dome 26 is provided with a detent 52, this detent being adapted ~o engage keeper 32 at the for~7ard end of control member 30. It will now be seen that con~rol member 30 is slidably mounted in base 18 below platform 24.
One end of a coiled tension spring 56 engages a hook 58 on the control member 30 and the opposite end of said spring 56 .engages a bar 60 on the base. It is by this means that the control member 30 is spring urged rearwardly in the base (rightwardly as viewed in Fig. 1). Control member 30 is provided with an end piece 62 which functions as a finger rest to enable the cnild playing with the toy to push the control member forwardly against the bias ~f spring 56.
; It will now be understood that when dome 26 is manually swung downwardly into closed position, its detent 52 engages keeper 32 against the action of spring 56. See, for example, Fig. 2. To release the dome for spring urged movement into open position, all that need be done is to press against end piece 62 to move the contro~ member forwardly a distance sufficient to disengage keeper 32 from detent 52. The action of torsion spriny 44 will cause the dome to swing upwardly into open position. See Fig. 6.
Toy vehicle 10 is itself provided with a de~ent 70 which extends transversely of the longitudinal axis of the vehicle. This detent is engageable by keeper 34 on the control member 30. ~en detent 70 and keeper 34 are interengaged, as illustrated in Fig. 2, the vehicle is held in stationary position on platform 24 of base 18. Keeper 34 a3~
is mounted on slide 72 which is transversely slidable between flanges 74 on base 18. Projecting downwardly from slide 72 is a pin 76 which engages a channel 78 formed in control me~.ber 30.
Channel 73 extends, in part, longitudinally of control member 30 and, in part, at an angle thereto of approximately 45 degrees.
Channel 78 (reference being here made ~o the edges which define the channel) functions in the manner of a cam and pin 76 engages said channel and functions in the manner of a cam follower.
~en the control member 30 is caused to move forwardly against the action of spring 56, as long as pin 76 occupies the longitudinal section 78a of channel 78, pin 76 (and the rest of the assembly therewith, slide 72 and keeper 343 remains stationary.
However when pin 76 is engaged by the angled section 78b of channel 7~ said pin and the other members 34, 72 of the pin assembly, are caused to move laterally of the longitudinal axis of control member 30. See Fig. 8 where keeper 34 is shown in solid lines to occupy one lateral position and in phantom in another lateral position. When keeper 34 is in its solid line position in Fig. 8 it engages detent 70 on the toy vehicle and confines the toy vehicle in stationary position. When keeper 34 is moved rotatably into its phantom position in Fig, 8 it dis-engages detent 70 and releases the toy vehicle for forward movement under its own power.
The operation of the launching mechanism will now be understood. Toy vehicle 10 is placed on platform 24 of base 18 and dome ?6 is swung downwardly against the torsion of spring 44 until its detent 52 engages keeper 32. If the spring motor was not previously wound it should now be wound by means of stem 12 and knob 12a on said stem which protrude outwardly from the dome through a slot 26a formed therein. Detent 70 on the vehicle will engage keeper 34 on the control member and the vehicle will be held in stationa~y position. Control member 30 may now ~1399~
be moved forwardly against the action of spring 56 by pushing upon end piece 62, the extent of such forward movement to be sufficient to close keeper 32 to disengage detent 52. The dome will now swing upwardly under the influence of spring 44 and the way will thereby be cleared for egress of the toy vehicle. Control member 30 may now be pushed forwardly beyond the point of dis-engagement of detent 52 and until keeper 34 is caused to move laterally out o engagement with detent 70. The toy vehicle is now freed for forward movement under its own propulsion One of the features of the present invention resides in its ability to control the direction of movement of the toy vehicle. This objective is achieved by simply holding the wrist on which the device is mounted in such position as to face the toy vehicle in the direction in which it is desired to have it run. To make sure that the vehicle maintains its appointed course, at least initially, ramp 28 is provided in base 18. This ramp may be pushed forwardly to its operative position as shown in Fig. 1. It is provided with a pair of side rails 28a and 28b which serve to guide the vehicle in the appointed direction. Ramp 28 also performs the additional function of bridging the gap between platform 24 and a suit-able horizontal surface such as table top 80. See ~ig. 6.
The foregoing is illustrative of a preferred form of this invention and it will be understood that other forms are equally contemplated within the scope of the appended claims. Specifi-cally, the invention is not limited to any particular keeper-detent mechanism. Any catch mechanism which is adapted for two stage operation, that is, with a time lag between operations, would be suited for the purposes of this invention.
