DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

(10) A balloon tool in accordance with one embodiment of the invention disclosed herein is identified generally as 10 in FIG. 1. As described in detail herein, balloon tool 10 is configured to assist in filling a balloon with a fluid, such as water, and tying a knot in the neck of the filled balloon to prevent the fluid from leaking out. Balloon tool 10 includes an elongate body 12, a U-shaped body 14, a protrusion 16, a hose coupling 18, a first side wall 20, a second side wall 22, and a tooth 24.

(11) As shown in FIG. 3E, elongate body 12 is a cylindrical tube having a hollow channel 26 extending through the center of the elongate body 12 along a longitudinal axis of the elongate body 12. The elongate body 12 has a first end 28 that is coupled with the hose coupling 18 and a second end 30 that is coupled with U-shaped body 14. The elongate body 12 extends away from a first end 32 of U-shaped body 14. The elongate body 12 may be gripped by the hand of a user during operation and extends away from U-shaped body 14 to provide space for the user to fill and tie a balloon using U-shaped body 14, as described below.

(12) Referring to FIG. 1, hose coupling 18 has a hexagonal outer surface 34 designed to be easily gripped by a user's hand or by a tool. Hose coupling 18 has a cylindrical inner surface 36 with female threads formed therein. The threads of cylindrical inner surface 36 are preferably sized and configured to engage with the male threads at the end of a conventional garden hose. The cylindrical inner surface 36 surrounds an interior chamber 38 that is in fluid communication with the hollow channel 26 of elongate body 12 through a fluid inlet 39. An o-ring seal (not shown) may be positioned within the interior chamber surrounding fluid inlet 39 to form a seal between hose coupling 18 and a hose (not shown) engaged with the hose coupling 18. While hose coupling 18 is shown as being coupled with elongate body 12, it is also within the scope of the invention for elongate body 12 to be omitted and for hose coupling 18 to be directly coupled to the first end 32 of U-shaped body 14. Further, hose coupling 18 may be omitted from balloon tool 10 or substituted with another type of coupling configured to connect to a fluid source. Elongate body 12 and hose coupling 18 may also have different shapes than those disclosed above and shown in the drawings.

(13) As shown in FIG. 3E, U-shaped body 14 includes the first end 32, which is coupled to elongate body 12, and a second end 40, which is coupled to first side wall 20 and second side wall 22. U-shaped body 14 has a first side 42, shown in FIG. 3C, and a second side 44 that each extend from first end 32 to second end 40. U-shaped body has an apex 46, shown in FIG. 3A, that is positioned approximately midway between first end 32 and second end 40. A first half 48 of U-shaped body 14 is positioned above apex 46, and a second half 50 is positioned below apex 46. The outer diameter of U-shaped body 14 gradually decreases in size from first end 32 to second end 40.

(14) A hollow channel 52 is formed within U-shaped body 14 and extends from first end 32 to second end 40. U-shaped body 14 has a fluid inlet 54 at first end 32 and a fluid outlet 56 at second end 40. Fluid inlet 54 is in fluid communication with the hollow channel 52 of U-shaped body 14 and the hollow channel 26 of elongate body 12. Fluid outlet 56 is in fluid communication with the hollow channel 52 of U-shaped body 14. Fluid entering hose coupling 18 flows through the hollow channel 26 of elongate body 12, the hollow channel 52 of U-shaped body 14 and out through fluid outlet 56. The hollow channel 52 has a variable diameter that decreases in size from first end 32 to second end 40, as shown in FIG. 3E.

(15) Protrusion 16, shown in FIG. 3A, is coupled with the first half 48 of U-shaped body 14 and extends outward from the U-shaped body 14 away from first end 32 and beyond apex 46. Protrusion 16 is solid such that it is not in fluid communication with the hollow channel 52 of U-shaped body 14. Protrusion 16 includes a first section 16a that is coupled with U-shaped body 14 and that is generally cylindrical. Protrusion 16 includes a second section 16b that is coupled with first section 16a and that is generally hemispherical. Protrusion 16 is generally aligned with elongate body 12 and extends away from U-shaped body 14 in a direction that is aligned with a central longitudinal axis of elongate body 12. A triangular shaped web 58 extends from approximately the apex 46 of U-shaped body 14 to the end of second section 16b of protrusion 16. As described in more detail below, protrusion 16 ensures that a balloon does not move around U-shaped body 14 toward elongate body 12 when the balloon is wrapped around U-shaped body 14 during the process of tying a knot in the balloon.

(16) Referring to FIG. 1, first side wall 20 is coupled with the first side 42 of the U-shaped body 14 at the second end 40 of the U-shaped body 14. First side wall 20 extends outward from the second end 40. First side wall 20 has a first end 60 that is coupled to the U-shaped body 14 and a second end 62. Second side wall 22 is coupled with the second side 44 of the U-shaped body 14 at the second end 40 of the U-shaped body 14. Second side wall 22 extends outward from the second end 40 to form a slot 64 positioned between the second end 40 of the U-shaped body 14, the first side wall 20, and the second side wall 22. U-shaped body 14 includes an end surface 65 surrounding fluid outlet 56 that forms a root of slot 64. Second side wall has a first end 66 that is coupled to the U-shaped body 14 and a second end 68.

(17) As shown in FIG. 3F, there is a first distance X between the first end 60 of the first side wall 20 and the first end 66 of the second side wall 22 and a second distance Y between the second end 62 of the first side wall 20 and the second end 68 of the second side wall 22. The first side wall 20 and the second side wall 22 taper toward each other as they extend outward from U-shaped body such that the first distance X is greater than the second distance Y.

(18) Tooth 24 has a proximal end 70 that is coupled with second side wall 22 and a distal end 72. Tooth 24 is positioned within slot 64 and extends outward from second side wall 22 toward first side wall 20. Distal end 72 of tooth 24 is spaced a distance from first side wall 20 to form a gap between the distal end 72 of the tooth 24 and the first side wall 20. Distal end 72 of tooth 24 is hemispherical with a convex outer surface. Tooth 24 extends slightly toward U-shaped body 14 from proximal end 70 to distal end 72 of tooth 24 such that the distal end 72 is closer to the U-shaped body 14 than the proximal end 70. Tapering tooth 24 slightly toward U-shaped body 14 in this manner assists in guiding the neck of a balloon into slot 64 and through the gap between the distal end 72 of tooth 24 and first side wall 20. Tooth 24 has a concave interior surface 74 facing the U-shaped body 14. All exterior surfaces of tooth 24 are preferably smooth with no ridges or edges to prevent tearing a hole in a balloon that contacts tooth 24.

(19) The elongate body 12, U-shaped body 14, protrusion 16, hose coupling 18, first side wall 20, second side wall 22, and tooth 24 may be integrally formed together from the same material, for example, by molding. Alternatively, any one or more of these components of balloon tool 10 may be formed separate from the remaining components and then joined together as shown in the drawings in any suitable manner.

(20) In use, balloon tool 10 is configured for filling a balloon with a fluid, such as water, and tying the end of the balloon to prevent the fluid from escaping through the open end of the balloon. Balloon tool 10 is preferably used with a conventional latex rubber water balloon, but may be adapted for use with any type of suitable balloon. A balloon is filled with fluid using balloon tool 10 by first connecting a conventional garden hose to hose coupling 18. The first side wall 20 and second side wall 22 of balloon tool 10 are then inserted through the opening at the end of the balloon. The balloon tool 10 may be inserted through the opening of the balloon until the balloon covers the fluid outlet 65 shown in FIG. 1. The source of water is then turned on allowing water to flow through the hose, balloon tool 10 and into the balloon. Once the balloon is filled with a desired amount of water, the balloon is removed from the end of the balloon tool 10.

(21) Balloon tool 10 may then be used to tie a knot in the end of the balloon in accordance with the steps shown in FIGS. 4A-4F. First, as shown in FIG. 4A, the balloon tool 10 is oriented so that elongate body 12 is generally horizontal and U-shaped body 14 extends below elongate body 12. The balloon 76 is oriented so that the spherical end portion 78 of balloon 76 containing the water is positioned below balloon tool 10. A neck 80 of balloon 76, which extends from the spherical end portion 78 to an open end 82 of the balloon 76, is inserted into the slot 64 (FIG. 1) between the first side wall 20 and the second side wall 22. The neck 80 of balloon 76 slides through the gap between the distal end 72 of tooth 24 and the first side wall 20. The neck 80 of the balloon 76 may be positioned to contact the concave interior surface 74 of tooth 24, which helps retain the neck 80 of the balloon 76 within the slot 64 as the neck 80 is tied into a knot. When the neck 80 is positioned within slot 64, the neck 80 and open end 82 of balloon 76 are wrapped over the first side of 42 of U-shaped body 14 at approximately the apex 46 of U-shaped body 14. The neck 80 is approximately horizontal at the completion of this step and extends away from the spherical end portion 78 at approximately a 90 degree angle.

(22) Next, as shown in FIG. 4B, the neck 80 and open end 82 of balloon 76 are wrapped 180 degrees around the U-shaped body 14 so that the neck 80 wraps around the apex 46 of the U-shaped body 14 and partially covers the second side 44 of the U-shaped body 14. The neck 80 is approximately horizontal at the completion of this step and the open end 82 extends away from U-shaped body 14 in the opposite direction as at the end of the step shown in FIG. 4A. Protrusion 16 assists in retaining the neck 80 of balloon 76 wrapped around the apex 46 of U-shaped body 14 by preventing the neck 80 from moving upward toward elongate body 12.

(23) Then, as shown in FIG. 4C, the open end 82 of balloon 76 is inserted through the opening between U-shaped body 14 and the portion of neck 80 that is wrapped around the first side 42 of U-shaped body 14. The open end 82 of balloon 76 is pulled through this opening to begin forming a knot in the neck 80 of balloon 76. The neck 80 of balloon 76 completely encircles U-shaped body 14 at the completion of this step.

(24) Balloon tool 10 is then rotated 90 degrees, as shown in FIGS. 4D-4F, until hose coupling 18 faces down. The user then slides the neck 80 of the balloon 76 back through the gap between the distal end 72 of tooth 24 and the first side wall 20 and out of the slot 64. Gravity assists the user in sliding the neck 80 of the balloon 76 past the tooth 24 and out of the slot 64. When the balloon 76 is released from the balloon tool 10, a knot 84 is formed in the neck 80 of the balloon 76 to prevent the fluid within balloon 76 from leaking out of the open end 82 of the balloon 76.

(25) From the foregoing it will be seen that this invention is one well adapted to attain all ends and objectives herein-above set forth, together with the other advantages which are obvious and which are inherent to the invention.

(26) Since many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matters herein set forth or shown in the accompanying drawings are to be interpreted as illustrative, and not in a limiting sense.

(27) While specific embodiments have been shown and discussed, various modifications may of course be made, and the invention is not limited to the specific forms or arrangement of parts and steps described herein, except insofar as such limitations are included in the following claims. For example, balloon tool 10 may be solid with no hollow channels extending through it, in which case balloon tool 10 would only be used for tying a balloon and not filling the balloon with water. In such an embodiment, hose coupling 18 may be omitted. Further, it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
