Each rod having at least two diameters to provide a retaining edge so the balloon will not slide down onto the base during the knot tying operation. The base with dual rods can be attached to different holding devices such as a ring shaped device for inserting at least 1 finger or a handle shaped device for gripping. The knot tying operation consisting of holding the balloon against the side of the device and stretching the leading end around the rods to form a loop. The leading end is then crossed under the loop through a relief area and up between the two rods. The leading end is then pulled off of the rods to form a permanent knot. ## Claims ### Claim 1 A balloon knot tying device comprising: a base having a first side with first and second cantilever rods connected to the first side of the base; each of said cantilever rods having a first portion with a first diameter and a second portion with a second diameter, said first and second portions meeting at a retaining edge for retaining balloon material during knot tying; said second diameter smaller than said first diameter; said first portion proximal to the base, and the second portion distal to the base; said first and cantilever rods spaced from one another. ### Claim 2 (depends on 1) A balloon knot tying device in accordance with claim 1 wherein said first and second cantilever rods extend parallel to one another and non-collinear with one another and perpendicular to said first side of said base. ### Claim 3 (depends on 1) A balloon knot tying device in accordance with claim 1 wherein the second portion of at least one said first and second cantilever rods further comprises a tapered end. ### Claim 4 (depends on 1) A balloon knot tying device in accordance with claim 1 wherein said first and second cantilever rods extend parallel and non-collinear with one another from the base. ### Claim 5 (depends on 1) A balloon knot tying device in accordance with claim 1 wherein said base is mounted to a handle device. ### Claim 6 (depends on 5) A balloon knot tying device in accordance with claim 5 wherein said base provides a relief area intermediate said first and second cantilever rods to facilitate ease of balloon knot tying; and said first and second rods are symmetrically disposed relative to one another. ### Claim 7 (depends on 5) A balloon knot tying device in accordance with claim 5 further comprising a textured surface area on the sides of the handle to provide a frictional surface area to facilitate ease of balloon knot tying. ### Claim 8 (depends on 1) A balloon knot tying device in accordance with claim 1 further comprising a ring shaped device for attaching to a human hand by sliding over at least one finger. ### Claim 9 (depends on 8) The balloon knot tying device in accordance with claim 8 wherein the ring shaped device further comprises an aperture there through and at least one finger slides through the aperture during use. ### Claim 10 (depends on 8) The balloon knot tying device in accordance with claim 8 further comprising at least one textured surface area on a side of the ring shaped device providing a frictional surface area to facilitate ease of balloon knot tying. ### Claim 11 (depends on 1) A balloon knot tying device in accordance with claim 1 wherein said base provides a relief area intermediate said first and second cantilever rods to facilitate ease of balloon knot tying. ### Claim 12 A balloon knot tying device comprising: a base connected to spaced apart first and second cantilevered rods extending from a first side of the base; each of said first and second cantilevered rods having a second portion with a first length and a second diameter along the first length; said second portion extending from a proximal end closer to the base than a distal end; and a tapered end portion extending from a distal end of the second portion; said tapered end portion having a constant slope over at least a section of the tapered end portion. ### Claim 13 (depends on 12) The balloon knot tying device of claim 12 wherein the first and second cantilevered rods each further comprise a first portion having a first diameter at a proximal end of the first portion and the first diameter is greater than the second diameter of the second portion. ### Claim 14 (depends on 12) A balloon knot tying device in accordance with claim 12 wherein said base provides a relief area intermediate said first and second cantilever rods to facilitate ease of balloon knot tying. ### Claim 15 (depends on 12) A balloon knot tying device in accordance with claim 12 wherein said base is mounted to a handle device. ### Claim 16 (depends on 15) A balloon knot tying device in accordance with claim 15 wherein said base provides a relief area intermediate said first and second cantilever rods to facilitate ease of balloon knot tying. ### Claim 17 (depends on 15) A balloon knot tying device in accordance with claim 15 further comprising a textured surface area on the sides of the handle to provide a frictional surface area to facilitate ease of balloon knot tying. ### Claim 18 (depends on 12) A balloon knot tying device in accordance with claim 12 further comprising a ring shaped device for attaching to a human hand by sliding over at least one finger. ### Claim 19 (depends on 18) The balloon knot tying device in accordance with claim 18 wherein the ring shaped device further comprises an aperture there through and at least one finger slides through the aperture during use. ### Claim 20 (depends on 18) The balloon knot tying device in accordance with claim 18 further comprising at least one textured surface area on a side of the ring shaped device providing a frictional surface area to facilitate ease of balloon knot tying.
