With reference to figure 1, show the illustrative embodiments of catapult transmitter 10 in conjunction with Fig. 2. Catapult transmitter 10 has the main body 12 that is generally Y shape. Main body 12 comprises handle 14 and two arm components 16,18, and described arm component is by the spaced apart pre-distance of determining of middle section 17. Although main body 12 can be manufactured by timber or metal, for the toy of manufacture in enormous quantities, molded plastics is preferred. In order to reduce quality and to improve intensity, arm component 16,18 and handle 14 can use ribs 19 molded. And protuberance 20 stretches out from main body 12, for will be in object described below.

Each lower quiet pedestal 21 and upper mobile post 23 of including in arm component 16,18. The quiet pedestal 21 of two arm components 16,18 is molded together as single support member 25. Support member 25 is connected to handle 14. Each mobile post 23 is all connected to support member 25 at twist joint 31 places. Pivot pin 33 is from the bottom of each mobile post 23 to downward-extension. Pivot pin 33 engages the torque spring 35 that is arranged on quiet substrate 21 inner sides. Torque spring 35 applies deflection elastic force to pivot pin 33, and mobile post 23 is biased to unloading orientation as shown in Figure 1 by described pivot pin 33. But, if being overcome the power of the deflecting force of torque spring 35, they reverse, each mobile post 23 all can be along the direction rotation of arrow 37. The object of twist joint 31 is explained subsequently in detail.

The top of each mobile post 23 all stops with the part 22 that loosens amplifying. The object of loosening part 22 of amplifying is explained subsequently in detail.

Two elastomer elements 24 are provided. Elastomer element 24 can be the solid rope of elastomeric material or the part of elastomer tube. Each elastomer element 24 all extends straight between anchored end 26 and free end 28.

Anchored end 26 and free end 28 both pearl 27,29 terminations to amplify, described pearl 27,29 for good and all adheres to elastomer element 24. Pearl 27,29 is preferably made up of duroplasts, so that pearl 27,29 is indeformable in the time being subject to effect of stress by the operation of catapult transmitter 10. On the contrary, elastomer element 24 is elastomeric, and can flexibly be extended at least three times of their original length, and in the time being subject to effect of stress, does not tear or rupture.

The part of reinforced pipe 30 arranges around each elastomer element 24. Reinforced pipe 30 than flexible member 24 more slightly, harder and elasticity is less.

Although reinforced pipe 30 is placed around the part of elastomer element 24, reinforced pipe 30 is not bonded to or is connected in addition the elastomer element 24 of this material.

Anchoring port 32 is in the each middle formation of the arm 16,18 that loosens the catapult main body 12 below part 22 amplifying. Anchoring port 32 is of a size of the anchoring pearl 27 at anchored end 26 places that are contained in elastomer element 24. In the time that anchoring pearl 27 enters anchoring port 32, anchoring pearl 27 is wedged in place can not movement. This is connected to the anchored end of each elastomer element 24 26 on the arm 16,18 of catapult main body 12.

Two stopper element 34,36 are provided. Each stopper element 34,36 all limits the bottom slot 38 of rotating 90 degree. Stopper element 34,36 enters loosening in part 22 in the amplification at the top place of arm 16,18. Elastomer element 24 is passed in the slit 38 in stopper 34,36.

Therefore, in the time that elastomer element 24 extends through bottom slot 38, their bending 90 degree. As a result, the free end 28 of each elastomer element 24 all extends along horizontal direction toward each other in central area 17. As a result, two elastomer elements 24 have the free end 28 that extends toward each other and stop as cantilevered structure. Point be arranged with short distance at the free end pearl 29 of the end of elastomer element 24.

Stopper element 34,36 also engages an end of each part of reinforced pipe 30. The part of reinforced pipe 30 is also extended along horizontal direction toward each other as cantilever structure. Being supported with of being provided by reinforced pipe 30 helps stop elastomer element 24 sagging under gravity.

What stopper element 34,36 use binding agents and/or mechanical fasteners were connected to amplification loosens part 22, described machanical fastener example screw 39 as shown.

In conjunction with Fig. 3, with reference to figure 2, that can see is to provide safe bullet 40. Each safe bullet 40 is made by foam rubber or similar low-density polymeric formula. In shown embodiment, safe bullet 40 is spherical. Other shape that it should be understood, however, that for example aircraft shape and rocket shape can be used.

Passage 42 with slit forms in safe bullet 40. Each passage 42 with slit all has the end 44 of an opening. Two open end 44 with slotted channels 42 are all separated the pre-distance of determining. Distance between open end 44 with slotted channels 42 just with the pearl 29 at free end 28 places at elastomer element 24 between distance equate. Therefore, it should be understood that the band slotted channels 42 that can easily enter into safe bullet 40 at the pearl at free end 28 places of elastomer element 24 through the open end 44 of the passage 42 with slit.

Each band slotted channels 42 is all arranged with band slit duroplasts insert 46. The existence of duroplasts insert 46 stops the hard free end pearl 29 of elastomer element 24 to be hauled out from band slotted channels 42 by the safe bullet 40 of soft material.

In conjunction with Fig. 2 and Fig. 3 with reference to figure 4, should be appreciated that, in order to utilize catapult transmitter 10, people holds catapult transmitter 10 handling safety bullet 40, until enter in the open end with slotted channels 42 44 on safe bullet 40 at the pearl 29 at free end 28 places of elastomer element 24. This interconnects safe bullet 40 and the elastomer element 24 of catapult transmitter 10. Then safe bullet 40 is manually held and in a horizontal plane to rear haulage. This causes elastomer element 24 to stretch and stored energy. This action also applies torsion moment to the mobile post 23 of arm component, and described arm component overcomes the deflecting force of torque spring and works.

In the time that the moment of torsion being applied by the stretching of elastomer element 24 overcomes the deflecting force of torque spring 35, mobile post 23 starts to turn the orientation into shown in Fig. 4. This has two effects. The first, the strength of the elastomer element 24 of elongation is added the strength of torque spring 35 in the torsion of mobile post 23. This has improved the transmitting strength of whole catapult assembly 10, and does not increase the stress being stood by elastomer element 24. The second, the torsion reorientation elastomer element 24 of mobile post 23, so that elastomer element 24 is better towards direction that wherein they are stretched. This has stoped elastomer element 24 in the time that they are stretched, to have to experience any zig zag. This has greatly increased may be stored in the amount of the energy in elastomer element 24, and does not cause those elastomer elements 24 damage or wear and tear.

In the time that safe bullet 40 is released, the spring of memory in elastomer element 24 and torque spring 35 can be released with regard to moment. Catapult emitter assemblies 10 just changes over suddenly the not loading structure of Fig. 1 backward from the loading structure of Fig. 4. Result is safe bullet 40 by preacceleration. Once safe bullet 40 passes between the arm component 16,18 of catapult main body 12, free-ended pearl 28 just slides backward in band slotted channels 42, and exits the passage 42 with slit by their open end 44. Now, safe bullet 40 just departs from from elastomer element 24, and safe bullet 40 freely flies to forward.

The elastomer element 24 that it should be understood that catapult transmitter only can engage the bullet having with slotted channels 42, and described band slotted channels 42 is sized and is separated, to be contained in two pearls 29 at two free end 28 places of elastomer element. As a result, catapult transmitter 10 of the present invention cannot be launched stone, hoodle or manufacture especially that have must be with any other object of the passage of slit. Therefore the children that have catapult transmitter 10 only can launch the safe bullet 40 that is provided with catapult transmitter with catapult transmitter 10.

In the time that elastomer element 24 is stretched, they are easy to fracture most. If a fracture in elastomer element 24, less likely the second elastomer element 24 will be in that precise time fracture. Therefore the elastomer element 24 of fracture keeps being without damage, and absorbs the most of energy being discharged by the elastomer element rupturing. This stops the elastomer element of fracture to be lashed backward towards user's face.

The passage with slit 42 in safe catapult 40 have with from the identical diameter of the outward extending protuberance 20 of catapult main body 12. This can pierce in safe bullet 40 protuberance 20, and this safe bullet 40 is engaged with interference fit part. As a result, the safe bullet 40 not used can be connected to the main body 12 of catapult transmitter 10 and be fixed ready.

Illustrated in it should be understood that, be only exemplary with the embodiments of the present invention of describing, those skilled in the art can use many modification of this embodiment. For example, bow structure can have many different ornamental shapes. Similarly, arrow bullet can be constructed to aircraft, rocket ship or any other Flight Projectile. All this embodiments include in as the scope of the invention defined by the claims.
