Abstract

A toy top launcher simulating a space shuttle is disclosed for launching a rotating top having a circular enlarged end and a gear adjacent the opposite end onto a flat surface. The top launcher has a chamber for supporting the enlarged ends of a plurality of tops is a row. A discharge station is provided for discharging the leading top from the chamber to a starting launching position on a launch pad. The launch pad has a pair of spaced elongated edges defining an open-ended elongated slot having a gear track along one edge thereof. A launch slider is mounted for reciprocal movement on the launch pad, and in one direction of movement engages the top and urges the gear thereof into meshing engagement with the gear rack. Further movement of the slider imparts rotation and forward motion to the top, expelling the top from the open-end of the slot.

Claims

1. A toy top launcher for a top, said top having a circular enlarged end, an opposite end, and a gear adjacent the opposite end thereof, said launcher comprising:

a launch pad having a pair of spaced elongated edges defining an open-ended elongated slot;

a gear rack along one edge of the slot;

support means on the launch pad for supporting the top in a substantially vertical starting launching position with the gear in the slot;

magazine means for holding one or more tops prior to launching;

loading means for rotating a top from said magazine into the launching position; and

launch means on the launch pad for engaging the top and urging the gear thereof along the gear rack for imparting rotation and forward motion to the top and expelling the top from the open-end of the slot.

2. A toy top launcher according to claim 1 wherein the support means supports the top in a position slightly inclined from the vertical.

3. A toy top launcher according to claim 1, wherein said magazine means comprises holding means for holding a plurality of tops in a substantially horizontal orientation in a row in alignment with one another, and discharge means for discharging the leading top onto the top support means of the launch pad.

4. A toy top launcher according to claim 3 wherein the top further has a circular shoulder adjacent the enlarged end thereof, and wherein the holding means comprises launcher body means defining an elongated chamber for receiving the enlarged ends of each top, the body means having an inclined ramp for supporting the circular shoulder on the top, and a stop member for stopping the leading top in a discharge position.

5. A toy top launcher according to claim 4 wherein the discharge means comprises a movable ramp portion of the ramp at the discharge position, which is movable between a normal top holding position and a top releasing position.

6. A toy top launcher according to claim 5 wherein the ramp portion is pivotally movable and has a laterally extending post, wherein the launch means comprises a reciprocally movable slider having a plate engageable with the post for moving the ramp position between its normal top holding and top releasing positions.

7. A toy top launcher according to claim 5, and further comprising guide means defined by the body means for guiding a released top onto the top support means of the launch pad into the starting launching position.

8. A toy top launcher according to claim 2 wherein the top support means comprises a pair of railings engageable by the enlarged end of the top in its starting launching position, and post notches are provided in the edges of the elongated slot defining shoulders for engaging a portion of the top adjacent the gear.

9. A toy top launcher according to claim 8 wherein the portion of the top comprises an annular rib.

10. A toy top launcher according to claim 8 wherein the opposite end of the top comprises a rounded peg, the top further having a circular shoulder adjacent the enlarged end thereof, an annular rib adjacent the gear, and a peripheral recess adjacent the annular rib, and wherein the launch means comprises a slider mounted on the launch pad for reciprocal movement, the slider having a first notched plate for receiving and engaging the rounded peg for moving the slightly inclined top into a vertical position and the gear into toothed engagement with the gear rack.

11. A toy top launcher according to claim 10 wherein the slider further has a second notched plate, spaced from and parallel to the first notched plate, for receiving the peripheral recess on the top and holding the gear thereof into engagement with the gear rack.

12. A toy top launcher according to claim 11 wherein the slider further has a third notched plate spaced from and parallel to the first and second notched plates for receiving the circular shoulder on the top, whereby the first, second and third notched plates engage and propel the top along the longitudinal slot and out of the open-end thereof.

13. A method for launching a rotating top having a circular enlarged end and a gear adjacent the opposite end thereof from a top launcher onto a flat surface for spinning rotation thereon, the launcher having a launch pad provided with a pair of spaced elongated edges defining an open-ended elongated slot, a gear rack along one edge of the slot, support means on the launch pad for supporting a top in a substantially vertical starting launching position with the opposite end of the top and gear in the slot, magazine means for holding one or more tops prior to launching;

loading means for rotating a top from said magazine into the launching position and a reciprocally mounted movable slider on the launch pad having a shoulder engagable with the post for moving the ramp portion between its normal top holding and top releasing positions, the method comprising the steps of;

rotating the top from the magazine to a starting launching position with the top in a substantially vertical position, and the opposite end of the top and gear in the slot;

propelling the top along the slot by means of the slider causing the gear to engage the gear rack and to move therealong for imparting rotation to the top; and

expelling the rotating top out of the open-end of the slot onto a flat surface for rotation thereon.

14. A method for launching a rotating top according to claim 13 comprising the further steps of

storing a plurality of tops in said magazine;

discharging the tops from said magazine one at a time; and

guiding each top discharged from the magazine to the starting launching position.
