The field of technique to which the invention relates to generally applies to the field of fastening of cables, tubes and labelling plates with inscriptions and declarations, and specifically relates to a rubber tie for connecting electrical and other cables and fixing plates of different materials which contain manufacturers declarations, bar codes and other labels.

According to the International Classification of Patents (MKP, 2016.01), the subject invention is classified and labeled with the basic classification symbol F16G 11/14 which relates to devices or couplings that enable easy forming of adjustable loops, such as clamping sleeves; hooks or hinges with integral parts constructed in a way that they can be easily fastened to any place in a cable or a rope, by forming of loops, as well as by secondary clasification symbols B65D 63/10 which include flexible elements of an unlimited length, such as strips for binding in bundles; non-metallic ribbons or strips, or F16G 11/00, which define cable or rope fasteners for each other or for other items, as well as F16B 2/00 which mark the separable connection by clamping, using clamping fingers or strips.

TECHNICAL PROBLEM

A technical problem solved by the subject invention is the following: how to find a constructive solution for a rubber tie which enables simple and easy binding bundles of cables, as well as fixing plates indicating declarations, purposes, bar codes, coupling marks and other data, which can ensure the protection of connectors during transport, while at the same time being long-lasting, capable of being regulated, adaptable to the different sizes of the connecting cables, being easy to produce with the economically competitive price. BACKGROUND OF THE INVENTION

Nowadays there is a large number of ties used to bind the cables as well as to bind other elements used in agriculture, and most of them are made in the form of narrow strips that are symmetrically narrowed at one end while the opposite end is made of rectangular reinforcement with rectangular cross-sectional opening in the center, through which the opposed narrowed end is pulled through, whereby the durability of the position is achieved by having one side of the strip jagged at an angle and does not allow the withdrawal in the opposite direction. Such tapes are made of plastic, cheap to manufacture and are effective when they are used for permanent binding and they are used for disposable purposes. The basic disadvantage is that the tape used once can only be removed with the aid of a cutting tool and can not be used again so that one always must have a spare band when intervening. In time, such tapes can be broken, and are unsuitable for binding electrical cables because they are narrow, and can also lead to cutting of the protective wire covering, which often leads to short circuits or other damage.

By reviewing the available patent documentation and other technical documentation concerning the subject area and available technical and propaganda literature, the following was found:

In the document of the small patent 04MP the inventor Bozic Radovan described "External clamp for elastic hose clamping on the pipe or the like". This technical solution is based on the construction of a serrated clamp formed as a fork consisting of two arms with an opening, while the other end is shaped with an expanded tongue, which are made so that by means of the pliers the clamping ends of the clamp are placed in the appropriate opening after which the ends of the clamp are to be tightened until the tongue and the fork fits together. Such a solution is complicated and and it is not reliable enough, so the security of the connected cables is not achieved.

In the small patent document 1049U, the inventor Slobodan Kerecki from Zemun presented "Elastic clamp for clamping and fastening " consisting of an elastic band at the end of which there is a protruding casing of a parallelepipedal shape, in the middle of which a passage of a strip is made whose longitudinal side edges have denticulated teeth so that the tape can be pulled in one direction. After inserting the tape into the desired position, the plate is secured so that the overhanging lid is overlapped - which is then caught - welded in one of the known ways. This solution is also complicated, requires an auxiliary tool and extended time to set it to a protective position, and probably that was the reason why it did not come in wider use.

In US Patent Application US 2016/0325897 Al published on 10-11-2016 entitled "Ties for reusable cables" there is a tie made of semi-hard plastic material for binding of cables in the form of a narrow elongated strip with one jagged side, whose one end has a pointed, mildly arched top ending with an enlarged bulge and a clasp in the shape of the hollow prism axially divided by a height drop equal to the thickness of the strip, so that two longitudinal channels are formed in it, whereas the shorter toothed segment is made on the opposite flat side with the arched top. The working principle of the strip is that the end of the strip passes through one channel and the pointed top is placed through the second one, so that the toothed side of the strip passes over the shorter toothed segment at the top. When the tape is sufficiently tightened, the toothed parts cling and do not allow the loop to stretch in the opposite direction. This tape is also made of plastic and its sensitive part is an arrowhead which often breaks and the tape becomes unusable.

The TANTRADE company from Belgrade in the small patent document 947U showed an invention titled "Security clamp (lock) with a metal claw" which refers to the clamp made of an elastic-plastic band with a control plate and a metal claw. At the free end it narrows down and the conical surface turns into the shorter handle so that it is easier to enter the opening of the safety claw, which is further provided with a plate with a protruding casing with a cover, and a casing with an opening for placing the safety claw. The band and the plate are made of polypropylene copolymer, and the claw is made of the spring steel. Such a solution is extremely complex for production and even application so it is only recommended for binding packets or larger bags and it is not purposeful for wide application of labeling products and cable bindings due to its complexity and relatively high costs production.

SUMMARY OF THE INVENTION

The essence of the invention is that it is in accordance with the invention idea, and it presents a constructive solution for a rubber tie that allows easy and simple binding of the cables into the bundles as well as the fixing of the plates with declarations, the purpose, the bar code, the joining marks and other data, which basically consists of a rectangular strip having axially made twelve equal simetrically separated openings of the circular cross section and whose ends laterally and symmetrically become narrow and end with integrally made ball-shaped ends which have unequal diameters, wherein the lower end has a discharge with a rounded tip that makes easier puling of the ball-shaped ends through circular openings in the strip. The design of the opening and the size of the safety balls is calculated so that they are inserted by slight depression and, after insertion, they do not allow easy squeezing or separation.

The essence of the invention is that the rubber ties are made, depending on the length, corresponding thickness and hardness of 30 ShA, thus achieving a satisfactory breaking strength and greatly eliminating the frequent cracking that appears in the vast majority of strips that are widely used nowadays, so that they are often thrown away and have to be replaced frequently.

The novelty of the invention is in particular the fact that the rubber ties are made of natural India rubber of NR hardness 45 ± 5 ShA so that they have a significantly better stretching up to 600%, while the breaking strength is incomparably greater and is 20 MPa.

The novelty of the invention is also the fact that the tie according to the invention is suitable for attaching the manufacturer's declaration whether it is made on cardboards or other plates made of similar materials, since the strips for this purpose are made shorter and narrower, but at one end they have integrally made balls with a shorter narrow end that is simply inserted into the corresponding hole on the declaration plate, after which it remains attached to the article that is labeled in this way. This method of marking is long- lasting because the end of the tie can not fall without the use of force, with the note that the circular openings are made according to ball-shaped ends, ie they have smaller diameter.

The essence of the invention is also the fact that the binding of smaller bundles require smaller ties with an integral discharge in the shape of a wider tongue which serves to protect the connectors during transport. It is known that connectors are the most sensitive part of cable connections and that their quality protection reduces any possible errors and failures in the operation of power supplies. Such connections are not being used for binding declarations and bar codes.

With respect to similar widespread ties, the tie according to the present patent application has several advantages, some of which are the most important ones:

- reliable and safe of tearing when used; - has extremely simple construction that is practical and easy to handle;

- no special maintenance is required;

- it is considerably longer-lasting and more useful;

- can be easily serialized at a relatively low production cost.

DETAILED DESCRIPTION OF THE INVENTION

The subject invention completely solves the above defined technical problem. As one can see from the figures 2, 5, 6 and 7 of the rubber tie 1, according to the invention, has been made in the shape of rectangular strip whose ends 2, 3 are symmetrically narrowed so that in the narrowest part they have integrally made ball-shaped ends 4, 5, while the extension of the smaller ball end 5 has a shorter extension 6 with a rounded tip, and at the end of the narrowest end 3 there are reinforcements 7 on both sides of the ties 1, the shape of the triangular cross-section. Throughout the length of the tie 1, twelve equal circular openings 8 with diameters smaller than the diameter of a larger ball-shaped end 4 are arranged regularly. The tie 1 is made of rubber on the basis of natural Indian rubber, hardness of (NR) 45 ± 5 ShA and stretching up to 600% while its breaking strength is 20 MPa. Such ties 1 according to the invention are known to be better than similar ties, which are generally made of liquid silicone (LSR) having a hardness of up to 30 ShA, in which two problems occur, i.e. that they do not have a satisfactory breaking strength, and the other is that they often are being broken, after which they are useless and are thrown away. Silicone straps are difficult to put on labels, and they easily fall out, which is often a big problem when storing the products they designate. The way of functioning and use of the subject ties is simple and obvious from the previous description and the draft, so it is not necessary to describe it in detail. However, it should be noted that bonding of the bundle 18 is to be done by collecting together the elements 17 which make it, wrapping the tie 1, then it is slightly stretched and the ball-shaped end 4 is inserted into the corresponding circular opening 8, and after that the bundle 18 remains permanently fixed. The release of the bundle 18 from the tie is to be done by stretcing tie 1 slightly, and the ball-shaped end 4 is expelled from the opening 8 using the thumb. After that the tie 1 can be re-used for bonding the same or another bundle 18.

In case of the need to attach the labeling plate 11 or cardboard with bar code or bar code to a particular cable bundle and the like, the tie 1 is used with half the smaller ball- shaped end 5, whose end is a shorter rectangular integral extension 6 which is dimensioned so that by pulling and pressing it is pulled through corresponding circular opening 12 on the labeling plate 11 which carries a certain mark of the bundle 18. The binding of labeling plate 11 with the bundle 18 is performed in a way that the tie 1 is attaches to bundle 18 on the above described way. Since, depending on the manufacturer, there are different circular openings 12 on the labeling plates 11 for labeling declarations or bar code, the author predicts two large ball-shaped ends (5), in accordance to these openings 12, thereby preventing the fallout the ends of the tie 1 in the case of different sizes of openings 12 on the labeling plates 11.

In practice, there is often a need for straps which, in addition to holding the bundle 18 in the assembled position, need to protect the cable connectors because they are the most sensitive part of the machine subjected to mechanical damage, tearing, pulling connectors, etc., so the author invented for such cases the tie 1 with a protected segment 14 of cable connectors which is constructed in such a way that the ends thereof are terminated in integral narrowed narrowed rectangular extentions 15 with ball-shaped ends 5 which are dimensioned so that can be pulled through the respective circular openings 8 by pressing the thumb after wraping the protective segment 14. The protective segment 14 is constructed so that its wider flat end is integrally connected to the tie 1 while the free end of the semicircular shape is opposite to it, the material from which it is made is the same as the material from which the tie 1 is made. The connectors in the bundle ends 18 of the cable tied in this way are effectively protected against mechanical damage and pulling out when the bundle 18 is moved. When showing invention in the tie 1 there was shown thirteen equal symmetrically spaced openings 8, but the length of tie 1 and the number of openings 8 can optionally be changed according to the size of the bundle 18, or the number of elements 17 placed in it.

METHOD OF INDUSTRIAL OR OTHER APPLICATIONS OF THE INVENTION

The industrial fabrication of the subject invention is absolutely possible in factories for the production of rubber equipment and even in well-equipped pre-fabrication and craft workshops for the manufacture of rubber parts. The tie according to the invention can easily be made according to the standard documentation that experts from the field can make using the description and the draft of this application.

The invention is suitable for serial production and its application is especially recommended where a need for quality and long-lasting ties exist, as well as for labelling items which should keep the declaration data for a longer period of time.

Prototyping tests have shown that such ties are long lasting, resistant to tear and crack and suitable for reusage.
