MEANS TO TIE A BALLOON

FIELD OF THE INVENTION

This invention generally relates to tying a knot in a balloon and, in particular, using an assembly that will mechanically form and tie a knot in the balloon filled with air or a liquid.

BACKGROUND OF THE INVENTION

Balloons can be available in many sizes, shapes, and colors which can be filled with air, helium, or a liquid such as water. Once a balloon is filled, it must be closed to prevent the air or water from leaking or escaping from the opening. Usually this is prevented by tying the end of the balloon into a knot or tying a string or something similar around the balloon opening to close it up.

When tying balloons, especially in large quantities for events, parties, games, or water balloon fights; it can be difficult to pull the end of the balloon through the loop to tie a secure knot. Tying a balloon is laborious and sometimes very difficult. One problem with conventional methods to tie balloons is to make a complete knot. When manually tying a balloon you wrap the end of the balloon around your finger creating a loop, then you try to tuck the end of the balloon through the created loop. This is difficult which can cause sore fingers, improperly tied balloons, or torn ends.

The opening of a balloon can also be closed by tying some string, or something similar, around its end. There is difficulty with this method since air or water could leak out the balloon as the user is attempting to tie a completed knot in the string.

Due to these methods there are other devices which have been invented to assist with tying knots in balloons. However, these devices still require you to manually tie the knot either by physically pulling or tucking the end of the balloon through the loop created in the neck or pulling the neck of the balloon over its end. Many times these devices are not ergonomic or easy to use. This can still lead to improperly tied or damaged balloons, and can still be time consuming.

When tying balloons it is highly desirable that the user interface provides perfectly completed knots every time. It is also desirable to be able to tie many balloons quickly to reduce time, especially if you need to tie a large quantity of balloons for an event, such as a birthday party, or for throwing many water balloons on a hot summer day. Also, it is highly desirable to minimize the potential of wasting balloons which have improperly tied knots or have torn ends making them useless.

This present invention removes the need to manually pull the end of the balloon through the created loop which will lead to less frustration and makes tying balloons easier, faster, and more fun. The method to achieve this is to wrap the balloon neck around a round tapered barrel of the assembly. Then the end of the balloon is inserted into a hook feature. Once the end of the balloon is captured and secure in the hook feature, a spring loaded trigger mechanism is actuated by the user. This will automatically pull the end of the balloon through the created loop. Then the balloon is pulled off the barrel creating the knot in the balloon. The user releases the trigger and then pulls the end of the balloon out of the hook feature for a completely tied balloon. This invention eliminates the need for the user to manually form a knot to close up the opening of a balloon.

In order to make this invention easier for the user, the assembly includes a handle which will allow the user a convenient and ergonomic grip. The trigger mechanism has a friendly curved shape for the user's finger. This is similar to a toy gun so it will be easy for both adults and children to understand and use.

The hook feature with the trigger mechanism and spring are located inside the assembly case. The hook is formed by a slot that allows the end of the balloon to slide into it. The spring is also located between the trigger mechanism and the case. The spring will return the trigger mechanism to its original position after the trigger is released by the user. The process can be repeated to tie many balloons quickly and efficiently.

SUMMARY OF THE INVENTION

An object of at least one embodiment of the present invention is to provide a compact, self-contained assembly to tie a knot in the opening of a balloon. This will prevent air, helium, or liquid inside the balloon from leaking or escaping from the balloon opening.

In carrying out the above object and other objects of at least one embodiment of the present invention, an assembly for tying a knot in a balloon is provided. The assembly includes a case or housing, a hook and trigger mechanism, and a spring. The hook and trigger mechanism and spring are encapsulated within the case.

The assembly includes a two-piece case which includes a first half of the case and a second half of the case. These two case halves will encapsulate the hook and trigger mechanism and spring when assembled. The case can be assembled using snaps and/or fasteners. The case includes a round, tapered barrel at its end which allows the user to wrap the neck of the balloon around it creating the loop. The case also includes a handle which allow the user a convenient and ergonomic way to hold onto the assembly. The case opening stop ring at the end of the barrel diameter is smaller than the internal hook and trigger mechanism which will prevent it from sliding out. The case has an opening for the trigger to slide back and forth during its operation. Also the opposite end inside the case is a reactive case spring press surface that allows the spring to compress against when the trigger is pulled by the user.

The internal hook and trigger mechanism includes a hook slot and a trigger. This mechanism will be encapsulated inside the case when assembled and extends pass the case opening. The hook and trigger mechanism has a larger diameter than the case opening stop ring to prevent it from sliding out of the assembly. On the opposite end of the hook and trigger mechanism has a reactive mechanism spring press surface that allows the spring to compress against when the trigger is pulled by the user. The hook slot will allow the user to insert the end of the balloon into it and hold it in position. The trigger extends through a slot in the case and has a curved, friendly shape for a finger. As the trigger is pulled, the hook slot holding the end of the balloon will be pulled into the case barrel.

There is an internal spring in the assembly which is also encapsulated inside the case. The spring is located between the case spring press surface and the hook and trigger spring press surface. The spring will compress against these surfaces when the user pulls the trigger. When the user releases the trigger, the spring will expand to bring the hook and trigger mechanism to its original position.

Each half of the case may be formed as a molded part from a rigid, structural plastic in an injection molding process or 3D printing process for example. The handle could include a soft touch user interface, if desired. The hook and trigger mechanism may also be formed from a rigid, structural plastic. The spring may be of stainless steel to prevent rusting. The spring efforts will be defined by its diameter, thickness, and number of coils.

The assembly may include decorative accents, such as balloons, located on the case. The assembly can be of different colors to appeal to different users.

The process of tying the balloon using this invention is described using a balloon filled with a liquid, such as water. The user will hold the handle of the assembly in one of their hands. The user will press the neck of the balloon against the side of the case assembly. Then the user will pull the end of the balloon around the case barrel and behind the filled balloon creating a loop with the neck of the balloon. The end of the balloon will be inserted into the hook slot. After the end of the balloon is securely in the hook slot, the user will pull the trigger. As the trigger is pulled, the hook slot and the end of the balloon will be pulled into the case opening through the loop created around the case barrel. At the same time the spring will be compress. The user will pull the balloon off the case barrel creating a knot. Pulling the balloon taunt, the knot will be tightened to prevent any water from leaking out of the opening. The user will release the trigger which will expand the spring bringing it back to its original position allowing the hook slot and end of the balloon to slide out of the case opening. The end of the balloon is removed from the hook slot producing a fully tied balloon. Repeat the process for as many balloons as the user would like to tie.

Other technical advantages will be readily apparent to one skilled in the art from the following figures, descriptions and claims. Moreover, while specific advantages have been enumerated, various embodiments may include all, some or none of the enumerated advantages.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Referring now to FIG. 1, the invention has a case 10 that contains a case barrel 12 that is used to wrap the balloon around and a case handle 14 which the user holds. The case 10 has a case opening 18 that allows the internal mechanism hook and trigger assembly 24 to retract and extend. The internal mechanism hook and trigger assembly 24 has a friendly shaped trigger 26 which the user can actuate the assembly and an internal mechanism hook slot 28 which the end of the balloon can be inserted.

Referring now to FIG. 2, the internal mechanism hook and trigger assembly 24 which includes the internal mechanism trigger 26 and the internal mechanism hook slot 28 is shown on the retracted position indicated by the direction of the arrow.

FIG. 3 shows a center line section from FIG. 1 along the axis 3-3. The case 10 includes the case barrel 12, a handle 14, the case trigger slot 16, and the case opening 18. The case trigger slot 16 allows the internal mechanism trigger 26 to slide back and forth. The end of case 10 has a case opening stop ring 20 that prevent the internal mechanism hook and trigger assembly 24 from sliding out of the case 10. This is due to the internal mechanism stop ring 30 being located on the internal mechanism hook and trigger assembly 24 by being larger than the case opening 18. Inside case 10 includes a case spring press surface 22 that allows a friendly surface area for the spring 32 to compress against. The spring 32 is located between the internal mechanism spring press surface 42 located on the internal mechanism hook and trigger assembly 24 and the case spring press surface 22 which is included within the case 10. The internal mechanism hook and trigger assembly 24 has an internal mechanism spring press surface 42 that will compress the spring 32 against the case spring press surface 22 as the internal mechanism trigger 26 is pulled.

Referring now to FIG. 4, this section shows a center line section from FIG. 2 along the axis 4-4. The internal mechanism hook and trigger assembly 24 which includes the internal mechanism trigger 26 and the internal mechanism hook slot 28 is shown on the retracted position indicated by the direction of the arrow. By pulling on the internal mechanism trigger 26, the internal mechanism spring press surface 42 pushes against the spring 32 compressing it against the case spring press surface 22. When the internal mechanism trigger 26 is released by the user, the spring 32 will expand back to its resting position as shown in FIG. 3.

Referring now to FIG. 5, the invention is showing an example of the potential construction and components in an exploded view. The two halves of case 10 would contain the internal mechanism hook and trigger assembly 24 and the spring 32. The two halves of case 10 could be secured using snaps, separate fasteners, or a combination of both.

Referring now to FIG. 6, the user will hold a balloon against the case barrel 12 which is included in case 10 putting pressure against the balloon as indicated. The user will grip the exemplary balloon neck 38 of exemplary balloon 34 and pull in the direction indicated by the arrow.

Referring now to FIG. 7, the user continues to pull on the exemplary balloon neck 38 wrapping it around the case barrel 12 and then under the exemplary balloon 34. Meanwhile, the user is still applying pressure to the exemplary balloon 34 as indicated.

Referring now to FIG. 8, the user will tuck the exemplary balloon opening 36 or the end of the balloon into the internal mechanism hook slot 28 which is included in the internal mechanism hook and trigger assembly 24.

Referring now to FIG. 9, the internal mechanism hook and trigger assembly 24 is actuated by the user pulling the internal mechanism trigger 26. This will retract the internal mechanism hook slot 28 indicated by the direction of the arrows. This action will pull the exemplary balloon opening 36 and exemplary balloon neck 38 tucked into the internal mechanism hook slot 28 into the case barrel 12 which created the wrapped balloon loop. Not shown is the spring 32 inside the case 10 is now in a compressed state.

Referring now to FIG. 10, the exemplary balloon 34 is slid off the case barrel 12. The exemplary balloon opening 36 and exemplary balloon neck 38 are still secured by the actuated internal mechanism hook slot 28 which is included in the internal mechanism hook and trigger assembly 24.

Referring now to FIG. 11, the exemplary balloon 34 is pulled tight for form a knot 40. The exemplary balloon opening 36 and exemplary balloon neck 38 are still secured by the actuated internal mechanism hook slot 28 which is included in the internal mechanism hook and trigger assembly 24.

Referring now to FIG. 12, the user releases the internal mechanism trigger 26 which is included in the internal mechanism hook and trigger assembly 24. The spring 32, not shown, will push the internal mechanism hook and trigger assembly 24 back to its original position within case 10 as indicated by the direction of the arrows.

Referring now to FIG. 13, the exemplary balloon neck 38 is removed from the internal mechanism hook slot 28 which includes the balloon knot 40.

FIG. 14 shows the final exemplary balloon 34 including the knot 40 tied in the balloon neck 38 which prevents air or water, in the case of water balloons, from exiting the exemplary balloon opening 36.
