ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a fabric, especially a pierce-proof fabric comprising a plurality of interconnected scales which have the same basic shape, and bores to connect them to one another. The scales further have connecting members which extend into the bores of an adjacent scale, and which are formed directly on the scales. The fabric can, however, also be used for other purposes, e.g. as a decorative fabric.
BACKGROUND INFORMATION
Patent DE 30 39 520 A1 discloses a fabric in which the scales of the different rows are connected to the scales of the adjacent rows. A flat connection with simultaneous overlapping in the manner of roof tiles (forming an imbrication) is not realized there, since the individual scales at best push against, rather than overlap, one another in the respective row. Therefore, since a sharp object could penetrate such arranged scales by being inserted between the adjacent, non-overlapping scales, it is necessary, in order to obtain armor-plating, for the fabric to be embedded in additional material, or for even a plurality of fabrics to have to be disposed one behind the other. Only then can this fabric really provide sufficient resistance to being pierced. However, this leads to a considerable increase in weight of a pierce-proof fabric manufactured in this way.
As pierce-proof fabrics for protecting people, fabrics are also known which are produced by means of the scales being provided with bores and the individual scales then being interconnected by means of wire. This type of manufacture involves a relatively large outlay; however it meets at least the safety requirements in Europe.
As additional pierce-proof fabrics, protective wire fabrics which comprise a large number of interconnected rings are used, for example, in the butchery trade.
However in many countries, requirements exist which are not met by any of these fabrics. It is required that the pierce-proof fabrics also offer protection against sticklebacks and ice axes, which can penetrate the previously known fabrics unhindered.
SUMMARY OF THE INVENTION
Proceeding from this state of the art, the present invention proposes to solve the aforementioned problems by creating a fabric which is easy to manufacture and also meets increased safety requirements.
This problem is solved by a fabric comprising a plurality of interconnected scales, these scales being arranged in the manner of roof tiles with each scale overlapping at least two adjacent scales. The scales comprise bores and connecting members for interconnecting the scales.
In this fabric, the scales are no longer interconnected via separate connecting members, such as wire rings, for example. Instead of this, the connecting members are formed directly on the scales, such that overlapping of the scales arises of its own accord when the different scales are connected. In this way it is no longer possible for sticklebacks to pass through between the scales. The only parts which could perhaps be penetrated are the bores into which the connecting members extend. However, the bores' diameters can be so adapted to the respective requirements that practically no further risk remains. The connecting members themselves are manufactured from the same material as the scales so that they also cannot be bent open easily, even if an attacker tries to penetrate the fabric by force. However, through the interplay between the bore and the connecting member, sufficient mobility is produced.
The fabric is also suitable for other areas of use such as, for example, in the ornamental or decorative field. Not only is there an aesthetic, largely closed exterior, but as a result of the very extensive mobility, this fabric can be used for many purposes, such as a wrist strap or as a basic material for manufacturing bags.
