Definitions

  • the present invention improves arm, leg and torso protective clothing made from metal ring braid.
  • Protective clothing made of metal ring mesh is worn by people who handle tools, machines or objects that pose a particular risk of injury, in particular cuts to the body, especially the limbs, e.g. B. by butchers or by workers in the glass industry who have to handle sharp-edged glass panels, or by workers in the metal industry who have to handle metal sheets, or by workers in the cardboard packaging industry who work on cutting or standing devices, to name just a few of the possible uses of such To name protective clothing.
  • Metal ring meshes have so far proven themselves well for such purposes because they offer sufficient protection against injuries and, because of their excellent flexibility, they nestle comfortably against the body and do not hinder movements of the body.
  • a metal ring braid is understood to mean a metal braid which is constructed from metal rings which loosely wrap around one another.
  • the high flexibility of the metal ring mesh also has disadvantages, such as. B. is clear from the example of a forearm protection, which can be attached to a glove as a cuff. If this forearm protection consists of a metal ring mesh, it will collapse and contract in the area of the wrist if you do not extend it to behind the elbow and fix it there with a strap that surrounds the arm, but this affects the mobility of the arm.
  • the invention has for its object to find a metal ring braid for arm, leg and torso protective clothing that combines increased rigidity and dimensional stability with sufficient conformability.
  • the strands made of the flexible material stiffen the metal ring braid in its longitudinal direction. As a result of this stiffening, the metal ring braid can no longer be pushed together in the longitudinal direction of the strands, but can still bend and thereby adapt to the contours of the body part which is to be protected, even during movements.
  • the metal ring braid that remains free between the strands retains its original flexibility and ensures a pronounced conformability even of the stiffened metal ring braid.
  • strands that cross or do not intersect can be provided in the metal ring mesh (claims 12 and 13).
  • the metal ring braid is at intersecting strands. stiffened in two dimensions: it cannot be pushed together in any direction.
  • Such a braid is particularly suitable for protecting parts of the fuselage, for example as chest protection.
  • the metal ring mesh can be easily pushed together in the direction transverse to the strands and is highly flexible, similar to a bare metal ring mesh.
  • the strands should run essentially in the longitudinal direction of the arms or legs (claim 14) in order to push the braid together along the arms or legs from top to bottom, even without a specific definition on To prevent arm or leg.
  • the degree of stiffening of the braid can be selected according to the intended use and can be set within wide limits by varying the distance, the width and the thickness of the strands and by the rigidity of the material used for the strands.
  • the intended embedding of the braid in the strands forms a stiffening bond between the strands and the metal ring braid, which makes the stiffened braid stiffer in the longitudinal direction of the strands than it would be the bare strands; therefore, the material for the strands themselves can be chosen to be quite soft, which benefits the conformability of the metal ring mesh.
  • the metal ring braid In order to make the bond between the metal ring braid and the strands permanent and intimate, the metal ring braid should be embedded in them continuously over the entire length of the strands (claim 2), preferably in such a way that the metal ring braid is made of the material of the strands while covering the top and is penetrated through the underside of the metal ring mesh, so that a series of metal rings extending in the longitudinal direction of the strands is completely embedded in the flexible material.
  • the strands should therefore also be wider than the (largest) ring diameter (Claim 10), whereas the distance between adjacent strands that do not cross should be at least twice the ring diameter in order to maintain sufficient flexibility for the stiffened metal ring braid.
  • Suitable materials for the strands are those that allow the metal ring mesh to be embedded in it and can be easily bent, but still have a stiffening effect.
  • thermoplastics such as soft polyvinyl chloride, low-pressure polyethylene or soft polyamides (claim 3).
  • Strands made of a thermoplastic material can, for. B. in situ by an injection molding process.
  • the still bare metal ring braid is inserted between the two half-shells of a two-part hollow mold and the material (possibly also its preliminary products, e.g. monomeric substances from which the material in the hollow mold is formed by polymerization) is initially flowable under pressure and in predetermined amount injected into the mold.
  • the hollow form cannot be completely closed laterally due to the inserted metal ring braid, so that part of the injected material can emerge laterally from the hollow form and lead to a somewhat irregular contour of the strands, which, however, leads to the relevant properties of the strands not affected.
  • the two half-shells of the hollow mold can be removed as soon as the thermoplastic material has solidified (hardened) to such an extent that the strands retain their shape. Measures to accelerate the curing of thermoplastic materials are known to the person skilled in the art and can be carried out here if necessary.
  • Elastomeric plastics in particular silicone rubbers (claims 4 and 5) are particularly suitable for this process and for stiffening the metal ring mesh while maintaining good conformability and durability of the mesh provided with it.
  • thermoplastic materials for inserting strands into a metal ring braid starts with the formation of a strand of two thermoplastic strips, one of which is arranged on one side and the other overlapping it on the other side of the braid. By applying heat and pressure, these two strips can then be welded into a strand in which a strip of the metal ring mesh is embedded.
  • the strands should preferably be predominantly convex, at least on their upper side, i. H. rise noticeably beyond the top of the metal ring braid, which has an advantageous effect on the security of its anchoring in the braid and on the wear resistance. It is recommended for reasons of the strength of the anchoring of the strands in the metal ring mesh and to achieve a cushioning effect. to make the underside of the strands predominantly convex (claim 7), but expediently less convex than the top (claim 8).
  • Predominantly convex should mean that the strands should be raised above all in their central area, whereas their edge area advantageously does not fall steeply, but flatly into the metal ring mesh, in order to offer as little contact surface as possible for the strand materials to rub off the metal ring mesh at the edge of the strands .
  • the metal ring mesh 1 shown is formed in all examples from identical circular rings 2. Within the network, each ring 2 is linked to four neighboring rings; at the edge of the braid and at seams which are formed to adapt the shape of the braid to the contour of a part of the body, the degree of concatenation is of course less.
  • Figure 1 shows a piece of metal ring braid 1, in which a strand 10 made of elastomeric material, in particular plastic, is anchored.
  • the strand 10 is slightly arched, which can be useful for adapting to the contours of a part of the body or to the movement of limbs.
  • differently shaped - in particular rectilinear, also crossing strands - could be anchored in the metal ring braid 1.
  • the upper side 4 of the strand 10 covers part of the upper side 6 of the metal ring mesh and the lower side 5 of the strand 10, which is curved less than the upper side 4, covers a corresponding part of the underside 7 of the mesh.
  • the width B of the strand 10 is approximately twice the outer diameter d of a ring 2.
  • the strand 10 shown in FIG. 3 made of elastomeric material, in particular plastic differs from that from FIG. 2 in that its height at the top 6 of the braid - represented by the upper tangent plane of the braid shown in dashed lines - is measured accordingly its width B, is smaller than the width B 2 , which is measured at the height of the underside 7 - represented by the lower tangent plane of the braid shown in broken lines - and both width dimensions are larger than the outer diameter d of a ring 2.
  • the lateral edge 8 the strand 10 is therefore not on the top of the braid 1, but near the bottom of the braid and is protected against rubbing off.
  • the top 4 is more convex than the bottom of the strand 10.
  • edges 8 of the strand 10 are shown idealized, their shape will usually be irregular in practice.
  • the figures only show a section of a metal ring mesh with a single strand.
  • the cross-sectional shapes shown can of course be realized accordingly if a plurality of strands are arranged at a distance from one another in the mesh or cross one another.
