FIELD OF THE INVENTION
The present invention relates to a launching device for launching a toy rocket operated by pressure and the activation member of the launching device steadily launches the toy rocket.
BACKGROUND OF THE INVENTION
A conventional launching device “B” for launching toy rocket from a stand “A” is shown in FIG. 9 and generally includes a control member “B2” which has one end secured on the stand “A” by a threaded sleeve “B 1” and the other end of the control member “B2” is connected with the injection nozzle on the rocket “C”. A plate “B3” has one end connected to the control member “B2” and includes an extension “B31” to which one end of a cable “A1” is connected. The rocket “C” is made by a bottle in which a proper pressurized air is filled. When the cable “A1” is pulled, the launching device “B” is activated and the rocket “C” is launched from the stand “A”. However, the cable “A1” is connected the extension “B31” which is offset from the center of the control member “B2” and the rocket “C” so that the rocket “C” tends to tilt and might hurt people around the launching site. Besides, the rocket “C” has a weight which makes the rocket “C” to fall down to the ground by gravity. Once the rocket “C” is not launched along the expected path, the rocket “C” with the weight could injure people.
The present invention intends to provide a launching device for toy rocket and includes an activation member which is connected with balance cables and the activation cable so that the activation member activate the control member and the injection nozzle without tilting the rocket.
SUMMARY OF THE INVENTION
The present invention relates to a toy rocket launching device that comprises a stand with a U-shaped frame pivotably connected thereto and a transverse plate is connected between two legs of the U-shaped frame. A control member has a first end connected to an injection nozzle of a toy rocket and a second end of the control member extends through a transverse portion of the U-shaped frame and is secured by a threaded sleeve. A valve is inserted into the first end of the control member and engaged with the injection nozzle of the toy rocket. A cap is mounted on the first end of the control member. An activation member is located between the transverse plate and the transverse portion of the U-shaped frame. Multiple balance cables are connected between the activation member and the cap. An end of an activation cable extends through the transverse plate and is connected to a center of the activation member, the other end of the activation cable is connected with a trigger device 40.
The primary object of the present invention is to provide a toy rocket launching device which launches the toy rocket without tilting the toy rocket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, the toy rocket launching device of the present invention comprises a stand 10 which is a board and two lugs 11 are connected on a top of the stand 10. A positioning unit 20 includes a U-shaped frame 21 which includes two legs and a transverse portion connected between the two legs, the two legs are pivotably connected to the two lugs 11 on the stand 10. A transverse plate 22 is connected between two legs of the U-shaped frame 21 by bolts 23.
A control unit 30 includes a control member 31 which has a first end connected to an injection nozzle 51 of a rocket 50 and a second end of the control member 31 extends through the transverse portion of the U-shaped frame 21 and is secured by a threaded sleeve 33. A valve 32 is inserted into the first end of the control member 30 and a cap 34 is mounted on the first end of the control member 31. The valve 32 is engaged with the injection nozzle 51 so that pressurized air can be supplied into the toy rocket 50 via the injection nozzle 51. The cap 34 includes a flange through which four holes 341 are defined therethrough.
An activation member 24 which is a circular disk and includes four holes as well. The activation member 24 is located between the transverse plate 22 and the transverse portion of the U-shaped frame 21. Four balance cables 42 are connected the holes 241, 341 in the activation member 24 and the cap 34 so as to connect the activation member 24 and the cap 34 together. An end of an activation cable 41 extends through the transverse plate 22 and connected to a center of the activation member 24. The control member 31 includes an inner tube 310 and a plurality of pivotable members 311 (only one is shown) are engaged in the inner tube 310 so that the injection nozzle 51 can be temporarily connected with the control member 31. The pivotable members 311 are pushed by the cap 34. The other end of the activation cable 41 is connected with a trigger device 40.
Referring to FIGS. 7 and 8, the toy rocket 50 includes four positioning plates 53 extending perpendicularly from an outer periphery of a tail end thereof and each positioning plate 53 has two first elongate slots 530. Four tail wings 54 each have two second elongate slots 540 which are located in alignment with the first elongate slots 530. Four securing members 55 each have two securing plates 550 extending from one surface thereof and the securing plates 550 extend through the first and second elongate slots 530, 540 to connect the trail wings 54 to the positioning plates 53. Each of the securing plates 550 includes tapered hooks 551 which extend through the first and second elongate slots 530, 540 to prevent the tail wings 54 from disengaging from the positioning plates 53.
As shown in FIG. 4, a pipe 61 is connected to the valve 32 and supplies air into the interior of the body of the toy rocket 50 in which a proper amount of water is received. After a proper pressure is reached, the U-shaped frame 21 is pivoted to set the toy rocket 50 pointing a desired angle. When operating the trigger device 40, as shown in FIGS. 5A, 5B and 6, the activation cable 41 is pulled and the activation member 24 and the cap 34 are both pulled, the pivotable members 311 are then pivoted because the cap 34 is pulled downward, the pressure in the toy rocket 50 is released from the injection nozzle 51 which is then disengaged from the control member 31 and the toy rocket 50 is launched. The four balance cables 42 are connected to the activation member 24 and the flanges of the cap 34 at even intervals so that the pulling of the activation cable 41 does not tilt the toy rocket 50.
As shown in FIG. 3, the activation member 24 can be an elongate member and only two balance cables 42 are needed which are connected on two ends of the activation member 24 and on diagonal line of the flange of the cap 34.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
