The invention relates to mechanical engineering and can be used for the manufacture of reinforced protective piercing-cutting strips of any design and purpose. The tape includes a central portion and a large number of pairs of opposing elements integrally formed with it. A pair of elements disposed along the central area of the belt uniformly. Each element consists of a pair of base and opposing prongs, formed from the outer side member. Each of the prongs acute angles are formed between the outer side and the sides of the element. Between the sides of elements adjacent pairs of elements, formed the inner wide space, external constraints sharp prongs of these elements. The tape is completely made of plastic or any other composite material, such as glass cloth impregnated with epoxy resin. The central portion of the tape is made thicker and functions as a reinforcing member. To increase the elasticity, the inside of the central thickened portion further infused during formation of the tape, for example, extrusion, metal wire of any section of the steel. Provides resistance to corrosion, increasing resource use, reduced weight, provided the product aesthetics and non-waste production.
The invention relates to a wire production, and more particularly to the production of piercing and cutting bands, are used as safety barriers designed to prevent undue penetration of sensitive sites, and can be used in the manufacture of reinforced protective piercing-cutting strips of any design and purpose.
Known a barbed wire consisting of a steel strip, in which are punched along its axis of symmetry, the perforation slots in which are mounted stellate spikes inserted in the slots of the tape at an angle to the longitudinal axis thereof, and then the tape encircle around the stud rolled and between grooves, twist along its longitudinal axis [see the copyright certificate USSR № 519 256 Class B21F 25/00 issued in 25.06.1976].
The main disadvantage of the given barbed wire should include the complexity of its production due to numerous manipulations stellate spines subsequent curling ribbon around its longitudinal axis. In addition, the tape attachment spikes may be considered unreliable – they can effortlessly straighten and remove the tape, thereby compromise the integrity of the safety barrier.
It is also known that a barbed wire consisting of a substrate made of weathering steel, and studs having an integral structure with a base, which are arranged symmetrically on both sides of the base and rotated about an axis relative to each other bases by the same angle, not more than 90°. Wherein each pin may be in the form of a pyramid or fence [see Russian Federation patent 2917355 Class B21F 25/00, published in 27.01.2003].
The disadvantage of this barbed wire is the complexity of its manufacturing process, because of the presence of spikes complex spatial configuration and orientation relative to each other and relative to the substrate simultaneously.
Also known barbed tape, comprising a central portion and a large number of opposed pairs of elements, integrally formed with it, wherein a pair of elements disposed along the central area of the belt uniformly, and each element in a pair consists of a base and opposing prongs, formed from the outer side element, and the tips of the prongs are each of the angles formed between the outer side member and sides, with elements between the sides, adjacent pairs of elements is constituted by a wide inner space which is bounded externally sharp prongs of these cells [see the Patent of Ukraine № 41834 class B21F 25/00, published in 24.04.2001].
The disadvantage of the given barbed tape is its low technical and functional properties. First, the well-known band is very easy to damage (for example, you can have a meal in any toolbox, even ordinary household scissors), because it is made of sheet metal. Secondly, known ribbon does not have sufficient elastic properties and has a small thickness, because of which it is readily and permanently deformed as a result of mechanical action (crushing can be simply clamped to ground by opening the free passage). Hence, from a known barbed tape cannot be trusted to build a barrier fence.
The closest in its essence and attainable effect is taken as a prototype, is reinforced barbed tape, comprising a central portion and a large number of opposed pairs of elements, integrally formed with it, wherein a pair of elements disposed along the central area of the belt uniformly, and each element in pair consists of a base and opposing prongs, formed from the outer side member, and the tips of each of the prongs are angles formed between the outer side and sides element, wherein between the sides of elements, adjacent pairs of elements is formed inside the wide space outwardly bounded cusps Prongs of these elements, and the central portion of the tape is reinforced central elastic wire of high carbon steel, preferably of circular section fixed and held on the tape rim of its central portion.
The main drawback of the known reinforced barbed tape is that it is made entirely of metal, particularly of metal strip and metal wire. It is known that metal under the influence of atmospheric precipitations easily and quickly corrode corrosion, so the manufacture of the known piercing and cutting a tape for a complete preservation of its technical and functional properties for a long period of operation should be used or galvanized metal or stainless steel, that is rather expensive materials. Otherwise, when using low-quality or low-carbon, so-called "black" metal known barbed tape in a year becomes unsuitable for further use. Reinforcement of such tapes should also be carried out exclusively high quality, high carbon stainless galvanized steel or spring wire for the same reason – corrosion.
Another essential disadvantage of the known reinforced barbed tape is that its connection with the main part of the reinforcing wire occurs by rolling the latter in the middle of the central portion of the tape. This type of connection is not sufficiently reliable: if the local bend the tape, for example, during the construction of the barrier – often used, necessary and ordinary operations – the edge of the central portion inevitably straighten releasing reinforcing wire, which is why the tape is automatically loses its elastic protective properties, namely those for which it reinforced. In addition, rolling – this is an additional step complicates the production, which, in turn, increases the cost of production.
There is also a significant disadvantage of the known barbed tape is the presence of large metal waste due to mismanagement of its cutting at stamping spike elements of the barbed tape.
Thus, due to the above drawbacks, reinforced piercing and cutting tape made on the basis of known technical solution has a high cost (additional operation reinforcement) has a fairly short period of serviceability (fast natural corrosion of metal) is waste (irrational technique patterns) and therefore is relatively expensive, because of which, especially given the need for a large number of linear meters of a tape construction of safety barriers, it is commercially unattractive to most potential users of such products.
The basis of the invention is to increase resource exploitation, simplification of manufacturing techniques and cost reduction reinforced barbed tape by improving its technical and operational characteristics by changing the material for the tape and the reinforcing wire connection type with its central portion.
This object is achieved in that the reinforced barbed tape, comprising a central portion and a large number of opposed pairs of elements, integrally formed with it, wherein a pair of elements disposed along the central area of the belt uniformly, and each element in a pair consists of a base and an oppositely directed prongs formed with the outer side member, and the tips of each of the prongs are angles formed between the outer side and sides element, wherein between the sides of elements, adjacent pairs of elements is formed inside the wide space outwardly bounded sharp prongs of these elements, and a central portion reinforced tape according supply tape is completely made of plastic or any other composite material, such as glass cloth impregnated with epoxy resin, wherein the central portion of the tape is made thicker and functions as a reinforcing member. To give further elastic properties to the inside of the central thickened portion of the tape may further be infused during the formation of the tape, for example, extrusion, metal wire of any cross-section of ordinary steel.
Proposed reinforced barbed tape, plastic has improved technical and operational characteristics: it does not corrode under the influence of precipitation is manufactural in production (non-waste technology – remote part of the plastic in the formation of pairs of elements back into the process as a raw material) is sufficiently elastic and has an unlimited service life and much less weight compared to similar products made from steel.
The thickened central portion of the belt does not need additional reinforcement as he performs his function. Consequently, the proposed reinforced barbed tape is made of only one type of material, using the commonly used plastics processing equipment, which greatly simplifies its production.
At the same time, modern plastics have virtually unlimited time performance indicators. For the production of the proposed reinforced piercing and cutting the ribbon, you can choose plastic with an optimal set of features that meet the purpose and the specific conditions of use of the product (in most cases using a high-strength refractory hard plastic). By request of the customer as the material can be used in any composite material such as fiberglass, impregnated with epoxy resin.
In addition, the proposed reinforced piercing-cutting of plastic tape has more aesthetic appearance due to the possibility for the customer to change the color of plastic, for example, aggressive or masking.
This additional reinforcement of the central portion of the metal wire, the wire rolling operation disappears – it merges with a plastic ribbon in a single structure during its manufacture. Link integrity bases tape with reinforcing metal wire eliminates the risk of corrosion on the surface of the latter, so you can use a wire of low carbon steel usual quality (so-called "black" steel), which is much cheaper galvanized or stainless steel. This can significantly reduce the cost of the finished product. Moreover, this type of compound (pour) no requirement for the configuration of the wire reinforcement section – its cross section may be any (circular, rectangular or arbitrary), and the size of the cross section of the wire is limited only by the thickness of the central portion of the plastic tape.
Thus, the totality of the essential features of the proposed technical solution regarding the reinforced piercing-cutting strips of composite materials allows achieving the desired technical result.
Further essence of the proposed technical solution is explained with illustrative pictures, showing:
- Figure 1 – a general view in plan reinforced piercing and cutting a tape of composite material;
- Figure 2 – the same, with the additional reinforcing metal wire in the central portion of the tape.
The given reinforced barbed tape is made, respectively, of a plastic (e.g., high fire-retardant plastic) tape comprising a central portion 1 and a large number of opposed pairs of elements 2, formed integrally with the central portion 1. The pairs of elements 2 are arranged along the central portion of the tape 1 equally and symmetrically. The distance between the pairs of elements 2 arranged side by side is approximately 30 mm. Each element of the two paired elements comprises prongs 3 and 4. The bases of the prongs of each island are three angles which are conjugate bases of the prongs 4 3. Between each pair of elements 2 on both sides of the central portion 1 is formed by the inner space 5 is wide, limited external sharp prongs 3. The central portion 1 is made thicker, for example, round, and can be reinforced with a glove in his metal wire 6.
Proposed reinforced barbed tape of composite materials is as follows.
When you try to overcome the barrier, made of this reinforced barbed tape prongs 3 pairs of elements 2 hold the offender without inflicting serious wounds and injuries, and the inner wide space 5 between adjacent pairs of elements 2 enhances the retention effect of the tape with respect to fragments of clothing and body intruder caught in the space 5. If you try to get rid of traumatic tip of a tooth 3, the offender gets on the tip of the tooth 3 element 2 adjacent pairs of elements 2, directed toward the first tooth 3, as the distance between the axis of symmetry of the adjacent pairs of elements 2 is chosen optimally for the purpose and is for example 30 mm. This increases the retention effect by several adjacent pairs of elements 2.
The presence of thickened reinforcing the central section 1 without a wire 6 or it does not allow to cut the barbed tape without using special tools, and press it to the ground, allowing you to create robust security barrier for protected sites and to adhere to the principle of humanity – not to cause serious wounds and injuries offender prongs 3 tape.
Significant distinction of the proposed technical solutions of earlier known similar solutions is that barbed tape is made of composite material, and its central portion is thickened or reinforced by further supplementing the metal wire. These differences, together, allow the operation to increase the resource to complete the destruction of the natural material and improve the technical and operational properties of a barbed tape and at the same time simplify the technology of its production, reduce its cost. None of the known piercing and cutting bands cannot simultaneously have these properties because they are not made of composite materials and have such a permanent connection with the reinforcing wire, moreover, fully protects it from corrosion.
The proposed technical solution tested in practice. Proposed reinforced barbed tape composite does not contain any elements or nodes that cannot be replicated at the present stage of development of science and technology, particularly in the production of piercing-cutting ribbons, therefore, it is suitable for industrial applications, has the technical and Other advantages over known analogs, confirming the possibility of achieving technical result of the claimed subject. In the known sources of patent and other scientific and technical information not found such reinforced barbed tapes of composite materials specified in the offer set of essential features, so the proposed solution it is considered to be such that it can receive legal protection.
The technical advantages of the proposed technical solution, as compared to the prior art include the following:
- Absolute resistance to corrosion due to use for the base tape pure plastic or composite material;
- Increase resource exploitation (resource exploitation is not particularly limited) for the same reason;
- Reduction of the total weight of the product for the same reason;
- Extension of technical and functional characteristics of the central portion of the belt due to the performance of its thickened;
- Providing aesthetic product with the ability to easily change the color of the plastic;
- Extension of the scope for the same reason;
- Non-waste production due to return directly to the process cut pieces of plastic.
Where the central portion is further reinforced, the technical advantages in comparison with the prototype are:
- Simplification of the manufacturing technology by eliminating a separate additional step of rolling the wire reinforcement;
- Reducing the cost of the product by allowing the use of relatively cheap for the reinforcement of the wire, for example, from ordinary low-carbon steel;
- The use of tape for reinforcement wire of any cross section and the thickness by connecting a plastic base with a wire ribbon into a unitary structure by injection;
- Increasing the reliability of the connection of the reinforcing wire with a base tape for the same reason;
- The absence of any special requirements for fasteners for the construction of reinforced barbed tape safety barriers due to the inertia of plastic.
Social benefits from the implementation of the invention, in comparison with the prototype, obtained by sticking to the principles of humanity in relation to offenders and improve aesthetics of safety barriers sensitive sites.
The economic effect from the implementation of the invention is in comparison with the prototype, obtained by reducing the cost of products, increasing the attractiveness of increased sales.
