Abstract

A toy launch apparatus for discharging soft foam darts, the launch apparatus having a cylinder, a piston, a launch spring, a dart magazine and a dart tube. The dart tube is biased by a return spring so that after a dart discharge the dart tube is moved rearward from a launch chamber to allow the magazine to spring load a fresh dart. During a cocking cycle the dart tube moves forward and receives the dart so that loading of a second dart is blocked. The automatic withdrawal of the dart tube after discharge of a dart also allows an empty magazine to be disengaged from the launch apparatus and a freshly loaded magazine to be attached. This may be accomplished without an operator having to take any other action thereby resulting in a very quick reload.

First claim

What is claimed is:

1. A toy launch apparatus comprising:
a housing;
a dart magazine for engaging the housing;
a cylinder mounted to the housing;
a piston mounted in the cylinder to enable relative movement between the cylinder and the piston;
a launch spring mounted in the housing for causing relative movement of the cylinder and the piston;
a dart surround structure mounted in the housing, the dart surround structure being movable between rearward and forward positions wherein in the rearward position a dart from the magazine is enabled to be loaded into a launch chamber and in the forward position a dart in the launch chamber is received by the dart surround structure and other darts from the magazine are blocked from entering the launch chamber;
linkage for moving the dart surround structure between rearward and forward positions while compressing the launch spring; and
a return spring connected to the dart surround structure for biasing the dart surround structure rearward after discharge of the dart.

2. The toy launch apparatus of claim 1 , including:
a cocking handle connected to the linkage for moving the dart surround structure.

3. The toy launch apparatus of claim 1 , wherein:
the linkage includes a first rack movably mounted to the housing, a second rack movably mounted to the housing, and a gear train mounted to the housing and to the first and second racks.

4. The toy launch apparatus of claim 1 , including:
a fastener for selectively restraining the dart surround structure.

5. The toy launch apparatus of claim 1 , including:
a fastener for selectively restraining the cylinder.

6. The toy launch apparatus of claim 1 , including:
a cocking handle mounted to the housing and being movable between forward and rearward positions;
said linkage comprising a first rack movably mounted to the housing and connected to the cocking handle;
said linkage further comprising a second rack movably mounted to the housing; and
a gear train mounted to the housing and connected to the first and second racks, wherein rearward movement of the cocking handle and the first rack causes the second rack to move forward.

7. The toy launch apparatus of claim 6 , wherein:
the second rack is connected to the piston and to the dart surround structure and rearward movement of the cocking handle enables forward movement of the second rack, which causes the launch spring to compress, the dart surround structure to move forward to receive a dart and the return spring to be extended.

8. The toy launch apparatus of claim 7 , including:
a first fastener for restraining the dart surround structure in a forward position.

9. The toy launch apparatus of claim 8 , including:
a second fastener for restraining the cylinder in a rearward position.

10. The toy launch apparatus of claim 9 , wherein:
movement of the cocking handle from a rearward position to a forward causes the first rack to move forward and the second rack to move rearward.

11. The toy launch apparatus of claim 10 , including:
a trigger connected to the second fastener for releasing the cylinder.

12. The toy launch apparatus of claim 11 , including:
a structure connected to the cylinder for releasing the dart surround structure from the first fastener.

13. The toy launch apparatus of claim 12 , wherein:
after release of the dart surround structure from the first fastener, the return spring moves the dart surround structure and the cylinder to their rearward positions; and
the magazine is enabled to be disengaged from the housing.

14. A toy launch apparatus comprising:
a housing;
a dart magazine for mounting to the housing;
a cylinder mounted to the housing, the cylinder being movable between a rearward position and a forward position;
a piston mounted in the cylinder and forming with the cylinder a pressure chamber;
a launch spring connected to the piston and to the cylinder for causing relative movement of the cylinder and the piston, the launch spring being movable between a relaxed configuration and a cocked configuration;
a dart surround structure mounted in the housing forward of the cylinder, the surround structure being movable between rearward and forward positions wherein in the rearward position a dart from the magazine is enabled to load into a launch chamber and in the forward position a dart in the launch chamber is received by the dart surround structure and other darts in the magazine are blocked from entering the launch chamber;
a return spring connected to the housing and to the dart surround structure for biasing the surround structure rearward after discharge of the dart from the dart surround structure;
a cocking handle mounted to the housing and being movable between forward and rearward positions;
a first rack movably mounted to the housing and connected to the cocking handle;
a second rack movably mounted to the housing, the second rack being connected to the piston and to the dart surround structure, wherein rearward movement of the cocking handle results in forward movement of the second rack which causes the launch spring to compress, the dart surround structure to move forward to receive a dart and the return spring to increase its biasing force;
a gear train mounted to the housing and connected to the first and second racks, wherein rearward movement of the first rack causes the second rack to move forward;
a first fastener for restraining the dart surround structure in the forward position;
a second fastener mounted to the housing for restraining the cylinder is the rearward position;
a trigger connected to the second fastener for releasing the cylinder; and
a structure connected to the cylinder for releasing the dart surround structure from the first fastener.

15. The toy launch apparatus of claim 14 wherein:
movement of the cocking handle from its rearward position to its forward causes the first rack to move forward and the second rack to move rearward.

16. The toy launch apparatus of claim 15 wherein:
after the trigger is pulled, the cylinder moves from the rearward position to the forward position causing the pressure chamber to contract and launch the dart in the dart surround structure.

17. The toy launch apparatus of claim 16 wherein:
after release of the dart surround structure from the first fastener, the return spring moves the dart surround structure and the cylinder to the rearward positions; and
the magazine is enabled to be disengaged from the housing.

18. A toy launch apparatus comprising:
a housing;
a dart magazine for mounting to the housing;
a cylinder mounted to the housing, the cylinder being movable between a rearward position and a forward position;
a piston mounted in the cylinder and forming with the cylinder a pressure chamber;
a launch spring connected to the piston and to the cylinder for causing relative movement of the cylinder and the piston, the launch spring being movable between a relaxed configuration and a cocked configuration;
a dart surround structure mounted in the housing forward of the cylinder, the surround structure being movable between rearward and forward positions wherein in the rearward position a dart from the magazine is enabled to load into a launch chamber and in the forward position a dart in the launch chamber is received by the dart surround structure and other darts in the magazine are blocked from entering the launch chamber;
a linkage for moving the dart surround structure from a rearward to a forward position while compressing the launch spring; and
