Wallet-bag

 

(57) Abstract:

Usage: the invention relates to light industry products, namely products of small leather goods, and can be used, in particular, wallets-bags-hosted chest pockets for storage of notes, business papers, business cards, passports and other similar flat objects. The inventive wallet-drying contains flexibly interconnected rectangular section, provided with pockets which have a stiffening of the fabric layers of polyparametric yarns with a linear density of 29-110 Tex, bonded firmware high-strength synthetic fibers and layers of paper. The volumetric ratio of fabric to the paper is in the range from 1:0.4 to 1:0.6, if their total surface density in the range of 40-100 g/DM2. 5 Il., table 1.

The invention relates to light industry products, namely, products small leather goods, and can be used, in particular, wallets-bags-hosted chest pockets for storage of notes, business papers, business cards, passports and other similar flat objects.

Known wallet made with the possibility of PE. otlichitelnye elements wallet are folding pockets, made on the inner side of the sheet, and folding pocket with transparent walls for business cards.

Also known connecting element wallet containing plate-like base jumpers for break-rotation and fixation when folding parts (USSR Author's certificate N 240214, And 45 5/12, 1969).

The disadvantages of such analogs should be their unreliability of protection against pistol bullets and stabbing objects that do not provide the security of the protected areas in the presence of wallets as barriers despite entered them in advance.

The closest analogue, selected as a prototype, is a wallet-bag, containing folding flexibly connected to each other, provided with pockets rectangular sections with stiffeners and bracing (USSR Author's certificate N 1797839 And 45 7/00, 1993). The prototype also has such disadvantages that does not meet consumer properties of reliable protection.

The main task is the development of a wallet-handbags such design of new materials, the use of which would eliminate the lo minimum value of the product.

The purpose of the invention improve the reliability and efficiency of use. The task and goal of the invention is achieved by changing the design and structure of the wallet-bag, the development of a new material, new volume ratio of the reinforcing stiffeners and minimum surface density of the wallet as a protective measure.

This wallet bag containing folding flexibly connected to each other, provided with pockets, a rectangular section with stiffeners and bracing, stiffening sections made of layers of fabric-based polyparametric (PAP) yarn linear density 29-110 Tex, bonded piercing high-strength synthetic fibers, and in the pockets between them placed layers of paper in a volume ratio from 1:0.4 to 1:0.6, if their total surface density of 40-100 g/DM2.

Distinctive features of the wallet-bag are the following features:

the implementation of the stiffening sections of the fabric layers on the basis of polyparametric (PAP) thread

linear density 29-110 Tex,

bonded high-strength bonding of synthetic filaments,

accommodation in the pockets between Il 1:0.6, if their total surface density of 40-100 g/DM2.

These distinctive features, each separately and all together aimed at solving the problem and achieving the objectives of the invention are significant, because a runtime exception of stiffening of the fabric layers on the basis of polyparametric threads and the total surface density of the layer at the specified their volumetric ratio does not allow to solve the problem and achieve the purpose of the invention.

The design of this wallet-bag is a reliable protection installed in high risk areas. The use of distinctive signs in the known solutions are not found, that characterizes the proposed technical solution according to the criterion of "novelty".

One set of new essential features of a General known provides a solution to the task and the goal of the invention and describes the proposed solution significant differences compared with the prior art, analogs and prototype is the result of research and experimental work, creative contribution to the solution of the problem in obtaining wallets-bags to protect Proektirovanie decisions and recommendations to the background. The new solution has the obviousness and meets the criterion of "inventive step".

In Fig. 1 is a perspective view of the wallet-bag in the open position of Fig. 2 in a collapsed position, Fig. 3 a front view, Fig. 4, the stiffening sections with layers of paper, Fig. 5 the scheme of interaction of ballistic bullet object with the wallet.

Wallet-bag contains supporting frame 1, made for example of a thin synthetic fabric or leather, with rectangular sections 2-5, flexibly interconnected pockets 6-11, the stiffening elements 12-14, made of layers 15 tissue-based PAP threads, and the layers 16 and 17 of paper. Layers 15 tissue stiffening 12-14 bonded piercing high-strength synthetic yarns 18. For the manufacture of stiffeners 12-14 used fabric from the PAP yarn linear density 29-110 Tex type 5363 thickness 0,46 mm Layers of fabric folded package and was transpierced high-strength synthetic yarns 18.

In the manufacture of stiffeners 12-14 and install them in the pockets 6-11 varied the number of layers 15 woven fabrics of PAP threads and layers 16-17 paper in a volume ratio from 1: 0.4 to 1: 0.6, if their total surface density of 40-100 g/DM2.

the actual volume of paper layers and the minimum total surface density layers stiffeners and paper of 40 g/DM2the piercing bullet is not observed (0%).

When the maximum volume of paper layers and the total surface density layers stiffeners and paper of 40 g/DM2penetration by a bullet there.

With minimal layers of paper and the maximum surface density layers stiffeners and paper 100 g/DM2penetration by a bullet there.

When the maximum amount of layers of paper and the maximum surface density layers stiffeners and paper 100 g/DM2penetration by a bullet there.

If there are layers of paper is less than the minimum volume minimum total surface density layers stiffeners and paper of 40 g/DM2breaking no.

If there are layers of paper is less than the minimum volume maximum total surface density layers stiffeners and paper 100 g/DM2takes place through the piercing in 40% of cases.

If there are layers of paper is greater than the maximum volume with the minimum total surface density layers stiffeners and paper of 40 g/DM2penetration by a bullet there, but wallet-bag gets too thick, weight and low maintenance properties, chastnosti% breakout.

The influence of linear density PAP yarn less than 29 Tex in the layers of tissue in the maximum amount of layers of paper and a minimum total surface density layers stiffeners and paper of 40 g/DM2is that the total strength of the fabric is not enough to absorb the energy of the bullet and its detention in the structure of the wallet-bag.

The influence of linear density PAP yarn less than 29 Tex in the tissue layers with the maximum volume of layers of paper and the maximum total surface density layers stiffeners and paper 100 g/DM2is that broken optimal combination of elastic dynamic characteristics of the protective package, while lyrically over 110 total frictional engagement of the threads in the fabric at the shock of the bullet drops below the limits required for "blanking" dynamic impact.

Wallet-bag defined therein a stiffening elements 12 to 14 and layers 16 and 17 of the paper was subjected to the test chamber high-speed pistol bullets caliber 9 mm with an initial speed of 315 m/s Positive test results was considered to be no holes in the wallet-bag.

The mechanism of interaction bullets with wallet-bag in St. the tissue stiffening 12-14 perceive the impact of dynamic load strength which can withstand it and leads to dessicatio the diffusion layers 16 and 17 of paper between them, acting as a damper. This interaction bullet stuck in layers and protect supergranny plot reliably protected from injuries.

Proposed wallet-bag has a high reliability, efficiency, reproducible by industrial means of production.

Thus, the use of the proposed technical solutions and corresponds to the criterion "industrial applicability", i.e. the level of invention, creation and use of appropriate protecting the exclusive rights of the patent.

Wallet-bag containing a foldable, flexible interconnected rectangular sections with stiffening elements, pockets and fixing means, characterized in that the stiffening elements are made of layers of fabric-based polyparametric yarns with a linear density of 29 110 Tex, bonded piercing high-strength synthetic fibers, and between them in the pockets placed layers of paper, with the volumetric ratio of tissue and paper is in the range of 1:0.4 to 1:0.6 total surface density of the fabric and the paper is in the
