Balloon gun and method

Abstract

A balloon gun comprising a hollow cylindrical body, one or more hand grips attached to the cylindrical body, a release trigger pivotally mounted on one of the hand grips or on the hollow cylindrical body and a balloon attaching mechanism. A balloon inflated with a fluid can be inserted inside the hollow cylindrical body and the inflated balloon is held by the balloon attaching mechanism. When the trigger is pressed the neck of the inflated balloon gets released from the balloon attaching mechanism and by the difference in fluid pressure that exists between the inside and outside of the balloon, the fluid rushes out of the balloon once the neck gets released from the balloon attaching mechanism and the force of the fluid coming out of the inflated balloon pushes the balloon forward and the balloon flies till the fluid pressures inside and outside of the balloon get equalized.

DETAILED DESCRIPTION OF THE INVENTION

(12) Embodiments of the present invention will be described in detail below with reference to attached drawings. Reference should now be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components. Further, the detailed description of well known functions and configurations that may obscure the gist of the present invention will be omitted.

(13) The making and using of various embodiments are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use, and do not limit the scope of the disclosure.

(14) FIG. 1 illustrates an isometric view of a balloon gun in accordance with an embodiment of the present invention. The balloon gun 100, in the present embodiment, will be referred to as Barrel Balloon Gun 100. The Barrel Balloon Gun 100 includes a cylindrical body 102 which is hollow, a rear hand grip 104 attached to the rear end of the cylindrical body 102, a trigger 116 pivotally mounted by a pin 126 (refer FIG. 2A) on the cylindrical body 102 or on the rear hand grip 104, a balloon attachment mechanism 118 and a front hand grip 106 attached to the forward of the cylindrical body 102. The main cylindrical body 102 with front end 112 and rear end 114 has a hatch 108 with hatch cover 110.

(15) In some preferred embodiments, the front end 112 of cylindrical body 102 is made to accommodate interchangeable plurality of removable barrels of various sizes and shapes to affect various trajectories and behaviors of a balloon when launched. In some other embodiments, a single barrel can be made to affect various trajectories and behaviors of a balloon when launched.

(16) With reference to FIG. 2A, in one preferred embodiment of the Barrel Balloon Gun 100, one end of a cord 120 is attached to a pin 128, which is situated at the opposite end of the finger grip of the trigger 116, and the other end of the cord is attached to the bottom of the balloon attaching mechanism 118 which is permanently attached to the gun and is designed to seal the balloon by squeezing the balloon filler neck. The cord can be passed over one or more pulleys 122 in such a way that, when the trigger 116 is pulled back towards the rear hand grip 104 by pressing it with a finger, the cord 120 pulls the balloon attaching mechanism 118 downwards against the spring 130. The downward motion pushes the balloon neck up and off the clip 118 which releases the balloon which lifts off of the clip 118. In another preferred embodiment of the present invention, the force required to actuate the balloon attaching mechanism 118 is transmitted from the trigger 116 through a linkage (not shown in the figures) instead of the cord 120.

(17) FIG. 2B shows another exemplary balloon attaching mechanism 118 for detachably attaching an inflated balloon to the Barrel Balloon Gun 100. In this embodiment, the balloon attaching mechanism 118 includes a lower clip 119, a upper clip 134 and a spring 130. The lower clip 119 is held affixed upright in the slot 136 made in the base 132, the base 132 being firmly mounted inside the cylindrical body 102. The filler neck 155 of an inflated balloon can be closed and sealed by use of a upper clip 134 prior to mounting into the Barrel Balloon Gun 100. The upper clip 134 holding the neck 155 of the inflated balloon can then be detachably attached to the lower clip 119 by simply pressing into it. In a preferred embodiment, the portion of the upper clip 134 holding the balloon neck 155 goes inside the arms of the lower clip 119 (arms of the lower clip are also referred to herein alternatively as a plurality of lower clip arms). As the trigger 116 is pulled, the cord 120 pulls the lower clip 119 inside the slot 136 and, in doing so, the arms of the upper clip 134 (the arms of the upper clip which engage with the arms of the lower clip are also referred to herein alternatively as a plurality of upper clip arms) get pressed outward by the raised top edges 202 of the slot 136 unlocking the engagement between the upper clip 134 and lower clip 119. As the arms of the upper clip 134 tend to move apart due to the outward force exerted by the raised top edges 202 of the slot 136, the upper clip 134 gets dislodged from the engagement with the lower clip 119 and the balloon neck 155 also gets released. The detachable upper clip 134 can be of disposable type or of reusable type. In some embodiments the balloon attaching mechanism 118 comprises of a permanent clip.

(18) Inflated balloons, sealed individually with upper clip 134, can be kept ready for quick loading into the Barrel Balloon Gun 100 with the help of an ammunition holder. In some embodiments, the Barrel Balloon Gun 100 can have an ammunition holder rail 117 as shown in FIG. 2. As shown in FIG. 8, the ammunition holder rail 117 is provided with plurality of clip holders 730. By sliding the button end 135 of the upper clip 134 onto these clip holders 730 one or more inflated balloons 150 can be kept ready for use. In some other embodiments, as shown in FIG. 7, a belt based inflated balloon holding arrangement 720 is provided. This belt based inflated balloon holding arrangement 720 can be easily worn over a common waist belt 710. The belt based inflated balloon holding arrangement 720 includes a plurality of clip holders 730 similar to those included in the ammunition holder rail 117 for holding plurality of inflated balloons 150. Although, only two embodiments of the inflated balloon holding arrangement have been described herein, it would be obvious to those skilled in the art that, keeping the spirit of invention intact the balloon holding arrangement can take many other shape and size.

(19) FIG. 3 and FIG. 4 show Barrel Balloon Gun 100 with an inflated balloon 150 detachably attached between upper clip 134 and lower clip 119. For loading an inflated balloon in the Barrel Balloon Gun 100, the neck 155 of the inflated balloon is to be pinched between the fingers and the neck 155 is inserted between the arms of the lower clip 119. Thereafter, the upper clip 134 is pressed over to get the neck 155 of the balloon locked and sealed between both the clips. The size of the hatch 108 (refer FIG. 1) is made big enough so that a person can open the hatch cover 110 and access the inside of the cylindrical body 102 where the balloon is required to be attached. As the trigger 116 is pulled, the clips 119 and 134 get unlocked and the upper clip 134 pops out releasing the balloon 150 from the balloon attaching mechanism 118. The difference in fluid pressure that exists between the inside and outside of the balloon 150 due to elasticity of the inflated balloon makes the fluid rush out of the balloon 150 once the neck 155 gets released from the balloon attaching mechanism 118. The force of the fluid coming out of the balloon 150 would push the balloon forward and the balloon would fly till the fluid pressures inside and outside the balloon 150 get equalized.

(20) In a preferred embodiment, the trajectory of the balloon 150 released from the Barrel Balloon Gun 100 of the present invention can be aligned, at least for some distance of the flight path, with the longitudinal axis of the cylindrical body 102. The more the distance the neck of a balloon traverse inside the cylindrical body 102 before leaving through the front end 112, the more is the possibility of the released balloon taking a straighter path aligned with the longitudinal axis of the balloon. Accordingly, in some preferred embodiments, the base 132 can be made to mount slidably on a rail (not shown in figures) inside the cylindrical body 102 so that a user can adjust the position of the base 132 to set the distance as per the preference of desired trajectory of the balloon released, which may also increase the forces of forward motion due to the elasticity of the balloon. In some preferred embodiments, the face of the base 132 towards the open end 112 of the cylindrical body 102 can be given such a shape which can facilitate launch of the balloon in a straighter or crooked path. The trajectory of the balloon becomes more unpredictable when it is released from a location near to the front end 112 of the cylindrical body 102. In some embodiments the inner surface of the cylindrical body, towards the front end 112 is made rifled with rifling designed to either affect a straight or curved trajectory, whereas, in some other embodiments, the inner surface is made smooth as per desired trajectory of the balloon propelling out of the Barrel Balloon Gun 100.

(21) FIG. 5A illustrates another embodiment of the balloon gun of the present invention. Hereinafter, this embodiment of the present invention would be referred to as Rail Balloon Gun 500. The Rail Balloon Gun 100, in the preferred embodiment as shown in FIG. 5A, includes a rail barrel 501, a hand grip 516, a trigger 514, a linkage 524, a one directional valve 522 and a balloon clasping mechanism 509. In a preferred embodiment, the rail barrel 501 can be longitudinally varying in cross-section. As shown in FIG. 5A, the cross sectional area of the rail barrel 501 varies from rear end 519 to front end 508 in three sections 502, 504 and 506 respectively. The rail barrel 501 has a longitudinal bore 518 made with both ends open and a unidirectional valve 522 installed in between.

(22) In some preferred embodiments, the front end 508 of rail barrel 501 is made to accommodate interchangeable removable barrels of various sizes and shapes to affect various trajectories and behaviors of a balloon when launched. In some other embodiments, a single barrel can be made to affect various trajectories and behaviors of a balloon when launched.

(23) The trigger 514 is pivotally mounted on pin 526 and the linkage is pivotally mounted on pin 528. The trigger 514 is connected to the linkage 524 by means of a pin. In a preferred embodiment, as shown in FIG. 5B, a clasping mechanism 509 comprising two concentric semi circular pieces of clamps 510 and 512 is mounted over the rail barrel section 504. The clamp pieces 510 and 512 sit tightly over the rail barrel 504 due to spring tension.

(24) Reference to FIG. 5A, FIG. 5B and FIG. 6, to load a non-inflated balloon into the Rail Balloon Gun 500, the neck 530 of the balloon is to be pulled over the rail section 504 axially with the trigger 514 in pulled condition so that the neck 530 of the balloon can be taken through under the clamps 510 and 512. The trigger 514 is then released and the clamps 510 and 512 hold the neck 530 of the balloon 150 tightly over the rail section 504 due to spring tension. The balloon 150 can then be inflated by blowing any suitable fluid such as air, nitrogen, helium etc. through the longitudinal bore 518 from the mouthpiece end 520. The unidirectional valve 522 prevents the fluid from coming out of the balloon 150 and due to the tight sealing produced by the engaged clamp 510 and 512, the balloon 150 gets inflated. When the trigger 514 is pulled, the clamps 510 and 512 move outwardly and the fluid present inside the balloon 150 tries to come rushing out through the loosened neck 530. The resulting force propels the balloon 150 out of the rail of the rail balloon gun 500. The reduced rail cross sectional area 506 makes sure that the balloon faces least amount of resistance due to friction when the balloon 150 leaves the rail.

(25) In another preferred embodiment, the one or more hand grips provided in the Balloon Gun of the present invention are not necessarily any extended or projected parts but a hand grip can be any portion of the main body of the Balloon Gun suitable for holding the Balloon Gun. For example, in case of the Barrel Balloon Gun 100, the hand grips 104 and 106 can be any portions of the cylindrical body 102 suitable for holding the Barrel Balloon Gun. Similarly, for Rail Balloon Gun 500, the hand grip 516 can be any portion of the rail barrel 501 suitable for holding the Rail Barrel Gun.

(26) In a preferred embodiment of the present invention, a method of using the barrel balloon gun comprises the steps of opening the hatch cover of the hollow cylindrical body by a user, accessing the inside of the hollow cylindrical body by the user, detachably attaching the neck of an inflated balloon to a balloon clasping mechanism by the user, holding the balloon gun at the rear hand grip and the front hand grip by the user and pulling the trigger back towards the rear hand grip by pressing the trigger with a finger by said user.

(27) In a preferred embodiment of the present invention, a method of using the rail balloon gun comprises the steps of pulling the neck of a non-inflated balloon over the front end of the rail barrel axially by keeping the trigger in pulled condition, taking the neck of the non-inflated balloon through under the upper half and the lower half of the balloon clasping mechanism, releasing the trigger such that the upper half and the lower half of the balloon clasping mechanism hold the neck of the non-inflated balloon tightly over the front end of the rail barrel, blowing a fluid through the longitudinal bore to inflate the non-inflated balloon and pulling the trigger to release the balloon which propels out of the front end of said rail barrel due to force of the fluid getting discharged from the balloon.

(28) Although few exemplary balloon attaching mechanisms are discussed herein, it should be obvious to those skilled in the art that many other forms of balloon attaching mechanisms can be used for the present invention.

(29) A skilled person in the art will appreciate that there can be many embodiment variations of this disclosure.
