Abstract

Claims (32)

1. A drive mechanism for launching a figurine, the drive mechanism comprising:

a housing including a hub;

a rotary drive supported in the housing and being drivingly engageable with the figurine for launching the figurine outwardly from the housing; and

a plurality of locking elements positioned around a perimeter of the hub, each locking element movable between a locked position, in which one of the locking elements engages the rotary drive to prevent movement of the rotary drive with respect to the housing, and an unlocked position, in which one of the locking elements is moved away from the rotary drive,

wherein the rotary drive includes a spring-biased pull string.

2. The drive mechanism of claim 1 , wherein one of the locking elements is movable toward the locked position when the housing is in a non-preferred orientation with respect to ground.

3. The drive mechanism of claim 2 , wherein, when the housing is in the non-preferred orientation, a longitudinal axis of the figurine is at an angle of less than about 80 degrees with respect to the ground.

4. The drive mechanism of claim 1 , wherein one of the locking elements is movable toward the unlocked position when the housing is in a launch orientation with respect to ground.

5. The drive mechanism of claim 4 , wherein, when the housing is in the launch orientation, a longitudinal axis of the figurine is substantially perpendicular to the ground.

6. The drive mechanism of claim 1 , wherein the perimeter is substantially circular.

7. The drive mechanism of claim 1 , wherein, one of the housing and the rotary drive includes a ramp oriented at an acute angle with respect to a longitudinal axis of the figurine, and wherein one of the locking elements is movable along the ramp between the locked position and the unlocked position.

8. The drive mechanism of claim 7 , wherein the locking element moves along the ramp toward the locked position when the housing is in a first orientation, in which the axis is at an angle of between about zero and about 80 degrees with respect to ground, and wherein the locking member moves along the ramp toward the unlocked position when the housing is in a second orientation, in which the axis is substantially perpendicular to the ground.

9. The drive mechanism of claim 1 , wherein when one of the locking elements is in the locked position, the locking element is wedged between the housing and the rotary drive.

10. A method of operating a drive mechanism having a housing and a rotary drive supported in the housing, the method comprising:

engaging a figurine with the rotary drive;

moving the housing and the figurine together toward a first orientation with respect to ground to move a locking element into engagement with the rotary drive to prevent movement of the rotary drive with respect to the housing;

moving the housing and the figurine together toward a second orientation with respect to the ground to move the locking element away from the rotary element; and

launching the figurine upwardly away from the housing,

wherein moving the housing and the figurine together toward the first orientation with respect to the ground includes moving the locking element along a ramp supported in the housing.

11. The method of claim 10 , wherein the figurine defines a longitudinal axis, and wherein launching the figurine includes rotating the figurine about the axis.

12. The method of claim 11 , wherein moving the housing and the figurine together toward the first orientation includes orienting the figurine such that the longitudinal axis is at an acute angle with respect to the ground, and wherein moving the housing and the figurine together toward the second orientation includes orienting the figurine such that the longitudinal axis is substantially perpendicular to the ground.

13. The method of claim 12 , wherein the acute angle is between about zero degrees and about 80 degrees.

14. The method of claim 10 , wherein the figurine defines a longitudinal axis, wherein moving the housing and the figurine together toward the first orientation includes orienting the figurine such that an angle defined between the longitudinal axis and the ground is less than a predetermined angle, and wherein moving the housing and the figurine together toward the second orientation includes orienting the figurine such that the angle defined between the longitudinal axis and the ground is greater than the predetermined angle.

15. A method of operating a drive mechanism of a flying toy, the method comprising:

providing a housing at least partially supporting a rotary drive;

engaging a figurine with the rotary drive;

engaging the rotary drive with a locking element to prevent rotation of the rotary drive with respect to the housing when a longitudinal axis of the figurine is oriented at an angle with respect to ground that is less than a predetermined acute angle;

disengaging the locking element from the rotary drive to allow rotation of the rotary drive with respect to the housing when the longitudinal axis of the figurine is substantially normal to the ground; and

launching the figurine upwardly away from the housing,

wherein engaging the rotary drive with the locking element includes moving the locking element substantially radially and along a ramp supported in the housing.

16. The method of claim 15 , wherein the predetermined acute angle is about 80 degrees.

17. The method of claim 15 , wherein the drive mechanism includes a plurality of locking elements supported in the housing adjacent to the rotary drive, and wherein engaging the rotary drive with the locking element includes moving at least one of the plurality of locking elements into locking engagement with the rotary drive.
