Subject of Invention The subject of the invention is a device and a method for coupling decorative balloons.

Technical Problem The technical problem solved by the invention is how to conceive a device and a method that would allow coupling of optional decorative balloons into clusters and/or chains of any forms, whereby the contact spot between each two balloons can be done anywhere on their surfaces and carried out in a place where the composition of decorative ballons is assembled in a simple and handy way that will not require any special manual skills and that will not represent a burden for fingers, whereby the conjunction can be disassembled in a simple and rapid manner without any danger for the balloons getting damaged.

Prior Art Known coupling of decorative balloons is based on a special type of balloons with attachments on certain spots. These attachments on balloons intended for coupling allow linking of balloons by knotting. A disadvantage of this solution is that coupling may only be performed between balloons with attachments and only on the place of attachments. This results in substantially limited creativity in the shaping of balloon compositions. Since balloons are coupled by manual knotting of attachments, burning abrasions or blisters are experienced when coupling some ten balloons, because the latex surface of the balloons is extremely unsliding.

A knot can be disassembled, yet it requires much skill, especially when two balloons are inflated and the knot tightened. There is a need for such solution of coupling decorative balloons that will allow coupling anywhere on the balloon surface and coupling of any balloon types, regardless of their shape, size and colour. Disassembly is also possible if the concept of the cluster changes while creating the composition.

Solution to the Technical Problem The described technical problem is solved by a device and a method for coupling of optional decorative balloons regardless of the type, size, colour and material and can be done anywhere on the surface of balloons.

The essential characteristic of the device of the invention lies in that it consists of a rod having a manual grip at one end and an attachment to receive an expanding element at the other, and of a clip collar. Such concept of the device determines the structure of the conjunction of both balloons, its essence being that the conjunction spot of shells of both balloons is arched into one of both balloons by means of the expanding element and that the shells are closed by a clip collar on the passage point of the arched part into the inflated parts, so that the expanding element is prevented from falling out.

The conjunction can be disassembled in a simple way by a removal of the clip collar.

It is understandable that a conjunction can be made anywhere on the balloon shells.

The essence of the invention will now be described in more detail by a description of an embodiment and the enclosed drawing, in which

Fig. 1 shows a device of the invention prior to use, Fig. 2 a device of the invention with positioned decorative balloons prior to coupling, Fig. 3 a device of the invention with positioned and coupled balloons; and Fig. 4 a detail of coupled balloons according to the method of the invention.

A device for coupling decorative balloons on an optional spot consists of a rod 1, conceived as a grip 2 at one end and as a seat 3 at the opposite end for an expanding element 4. The expanding element 4 is conceived as a body with a seat 5 being complementary to the seat 3. The expanding element is preferably conceived as a ball with a seat - hole, the diameter of which approximately equals that of the seat 3. The device further comprises a clip collar 6 encircling both balloons 7, 8 closely to the expanding element 3 in a way that the expanding element 4 cannot go through it. The clip collar 6 is preferably conceived as an elastic ring, the diameter of which is smaller than the width of the expanding element 4 in unburdened mode, or as a horseshoe, the gap of which approximately equals the thickness of the seat 3 and walls of two balloons.

The method for coupling decorative balloons consists of several steps. The first step is positioning of the expanding element 4 onto the seat 3, conceived on the rod 1. In the second step one balloon 7 is positioned onto the rod 1 with the expanding element 4 so that the spot on the shell of the balloon 7 intended to be coupled to another balloon 8 is positioned near the expanding element 4. In the next step another balloon 8 is positioned over the first balloon 7, so that the spot on its shell intended to be coupled with the first balloon 7 actually contacts the first balloon 7 on the expanding element 4. Follows positioning of the clip collar 5 over both balloons 7, 8 near the expanding element 4. If the element 5 is an elastic ring, it is drawn over the expanding element 4 and the balloons 7, 8, so that it tighthens both balloons 7, 8 closely behind the element 4 thus preventing it from falling out and also preventing both balloons from getting disassembled. If the element 5 is conceived as a horseshoe, it is positioned closely behind the element 4 from the side onto both balloons 7, 8. After both balloons are coupled as described above, one balloon after another is taken off the rod 1 and inflated by gas.

If we want to change the point of contact of both balloons, gas is discharged from their interior, turned in a way that the clip collar 5 is accessible and remove it manually. The conjunction is thus disassembled. The balloons are ready to be coupled on another spot.

It is understandable that a man skilled in this field can implement other embodiments based on the knowledge of the above invention, especially in the sense of industrial design, without circumventing the essence of the invention defined in the appended patent claims.
