Definitions
- the present invention relates to a made of a metal ring braid arm, leg and torso protective clothing.
- Protective garments made of metal ring braid are worn by persons who handle tools, machines or objects which involve a particular risk of injury, in particular cuts to the body, especially the limbs, for example in meat processing in slaughterhouses, in poultry and the fishing industry, as well as when working with sharp-edged objects in the metal industry, to name but a few of the uses of such protective clothing.
- Metal ring braids have been well proven for such purposes so far, because they provide adequate protection against injury and readily adapt to the body because of their excellent flexibility and movements of the body hinder. Under a metal ring mesh is understood a metal braid, which is constructed of metal rings that loosely entwine each other.
- the high flexibility of the metal ring mesh also has disadvantages such as e.g. becomes clear by the example of a forearm protection, which can be attached as a cuff on a glove. If this forearm guard consists of a metal ring mesh, it will collapse and collapse in the area of the wrist, unless stiffening is provided, which prevents collapse, e.g. by plastic or metal rails, or if you do not extend the forearm protection to behind the elbow and there by means of a strap surrounding the arm. Both, however, affect the mobility of the arm.
- a protective clothing which has a consisting of metallic ring links and cross-shaped scales existing scale mesh. By the described arrangement, a cleaning of the scale braid to be facilitated.
- a stab protection apron made of a metal mesh is known, in which rings made of stainless steel by flake-shaped connecting links made of light metal are joined together to reduce the weight of the metal mesh.
- the invention has for its object to provide a partially stiffened metal ring mesh for arm, leg and torso protective clothing, which is easier to clean, disinfect and inexpensive to manufacture.
- the metal ring mesh characterized in that in some areas chained together rings are metallically cohesively connected to each other.
- This can be achieved, for example, by welding or soldering, wherein welding, in particular by pressure welding, e.g. Spot welding or roll welding, inexpensive and is particularly preferred.
- This measure has the advantage that can be dispensed with non-metallic components of the protective clothing, resulting in an easy-to-clean protective clothing.
- Such protective clothing according to the invention can advantageously be sterilized at high temperatures and exposed to aggressive chemical and mechanical cleaning agents (detergents, disinfectants, strong brushes), for the use of which plastic would be too sensitive.
- protective clothing according to the invention is insensitive to mechanical cleaning processes and can be readily cleaned, for example, with high pressure water jet equipment and steam jet equipment.
- subregions of any geometry according to the invention can be stiffened. As a result, a favorable adaptation to a variety of uses and uses of the metal ring mesh and the protective clothing is achieved.
- Another advantage is that a metal cohesive connection with each other chained rings with little effort, in particular without additional components of the protective clothing, perform, so that the protective clothing can be manufactured inexpensively.
- Such Protective clothing on a smooth, comfortable to wear surface, in particular, the stiffened portions of lesser thickness than in the prior art and there is no abrasion.
- An advantageous development of the invention provides that a welding point connects four rings linked together. This measure has the advantage that such a partial area can be stiffened with as few spot welds as possible.
- the stiffened portions are strip-shaped. This measure has the advantage that the metal ring mesh can no longer be pushed together in the longitudinal direction of the strips, but retains its desired high flexibility transversely thereto.
- the longitudinal direction of the strips is best transverse to the longitudinal direction of the braid. In the direction of the metal ring mesh can be pushed together wrinkle-free to a relatively large extent, but not at right angles.
- the running direction is usually chosen to coincide with the longitudinal direction of the fingers, so that the metal ring weave readily participates in the movements of the fingers.
- an advantageous development of the invention provides that the extent of the stiffened portions, in particular the width of strip-shaped stiffened portions, is at least three times the outer diameter of the rings. This measure has the advantage that the stresses that require the stiffened strips to bend on a larger number of Distribute welding points, which results in a longer durability of the stiffeners.
- An advantageous development of the invention provides that the subregions are formed as interrupted strips. This measure has the advantage that a collapse of the metal ring mesh in the longitudinal direction of the strips is prevented and at the same time a certain flexibility is maintained by the interruptions of the strips, which increases the wearing comfort of the protective clothing.
- An advantageous development of the invention provides that the distance between non-intersecting, adjacent, stiffened portions is at least twice the outer diameter of the rings of the metal ring mesh. This measure has the advantage that the stiffened portions can be flexibly moved against each other, which preserves the comfort of the protective clothing.
- An advantageous development of the invention provides that the outer contours of the protective clothing are stabilized. For some applications, such as aprons, it is advantageous if the outer contours, so the edges are stiffened, while the inner region remains flexible.
- An advantageous development of the invention provides that the stiffened portions stabilize spherical structures. This measure has the advantage that the protective clothing can be adapted to the shoulders or head of the wearer, so that the wearing comfort is increased.
- an advantageous development of the invention provides that, depending on the intended use, parallel strip-shaped partial regions or intersecting strip-shaped partial regions are provided.
- the metal ring mesh is stiffened two-dimensionally, so that it in no direction can be pushed together unhindered.
- Such a braid is particularly suitable for the protection of parts of the trunk, eg as a chest protector.
- the metal ring braid is collapsible and highly flexible in the direction transverse to the strips, much like an unstiffened metal ring mesh.
- Such a braid is particularly suitable as arm or leg protection.
- the strips extend substantially in the longitudinal direction of the arms or legs to prevent collapse of the braid along the arms or legs even without any particular attachment to the arm or leg.
- the degree of stiffening of the braid can be selected according to the particular application and can be set within wide limits by varying the distance, the width and the thickness of the stiffened strip-shaped sections.
- the metal ring mesh 1 shown is formed from mutually identical circular rings 2. Within the braid, each ring 2 is concatenated with four adjacent rings; at the edge of the braid and at seams formed to match the shape of the braid to the contour of a body part, the degree of concatenation is naturally lower.
- Figure 1 shows a piece of metal ring braid 1, which is stiffened in the sub-areas 3a, 3b, 3c characterized in that in these sections 3a, 3b, 3c chained together rings by pressure welding metallically cohesively connected to each other.
- the portion 3a is designed as a continuous strip, while the sections 3b and 3c are designed as broken strips, which offers the advantage of greater flexibility.
- other shaped portions especially curved or crossing each other - strips in the metal ring mesh 1 are stiffened.
- the use of strip-shaped portions has the advantage that the stiffened surface kept low overall and at the same time the desired stiffening of the protective clothing can be achieved. The smallest possible stiffened surface lowers the manufacturing costs and increases the wearing comfort.
- the strip-shaped partial regions 3a, 3b, 3c shown in FIG. 1 have a width of three ring diameters.
- these sections 3a, 3b, 3c can also be made narrower or wider. However, the broader they are, the more the protective clothing loses its flexibility, which compromises wearing comfort. If the stiffened partial regions 3a, 3b, 3c are made narrower, a smaller number of spot welds 4 will be correspondingly more heavily loaded. This can lead to breakage of welds 4 or metal rings 2 and so affect the longevity of the protective clothing.
- Figure 2 shows a cross section of a side view of an unstiffened metal ring mesh 1.
- Figure 3 shows a corresponding cross section of a stiffened portion 3. The stiffening is carried out by pressure welding. As can be seen by comparing Figures 2 and 3, this also causes the Metal ring mesh 1 in the stiffened portions 3a, 3b, 3c noticeably flatter.
- Figure 4 shows in a plan view and in a corresponding sectional side view of a section of the metal ring mesh 1 an example of the intertwining of the rings 2.
- metal rings 2 are always four interconnected metal rings 2 by a weld point 4 metallically cohesively connected.
- the welding is done by Preßsch spaung. Of course, other welds or soldering are conceivable.
- pressure welding to achieve a cost effective permanent connection of four metal rings 2 linked together by a single spot weld 4. If you put the metal ring braiding for welding on a curved surface, then it can also stiffen spherical structures, so that an adaptation to the head or shoulder of the wearer is reached.
- the wearing comfort increases.
- Figure 5 shows a metal ring mesh 1 with a stiffened portion 3d as outer contour stabilization.
- the outer contours are stiffened, while the inner region remains flexible, which is favorable, for example, aprons.
- Such outer contour stabilization can be carried out continuously as shown in FIG. 5 or else interrupted.

Description
Die vorliegende Erfindung betrifft eine aus einem Metallringgeflecht hergestellte Arm-, Bein- und Rumpfschutzbekleidung.The present invention relates to a made of a metal ring braid arm, leg and torso protective clothing.
Aus Metallringgeflecht hergestellte Schutzbekleidungen werden von Personen getragen, die mit Werkzeugen, Maschinen oder Gegenständen umgehen, welche ein besonderes Risiko von Verletzungen, insbesondere Schnittverletzungen des Körpers, vor allem der Gliedmaßen, in sich bergen, z.B. bei der Fleischverarbeitung in Schlachthöfen, in der Geflügel- und Fischindustrie sowie beim Arbeiten mit scharfkantigen Gegenständen in der Metallindustrie, um nur einige der Einsatzmöglichkeiten solcher Schutzbekleidung zu nennen. Metallringgeflechte haben sich für solche Zwecke bislang gut bewährt, weil sie einen hinreichenden Schutz vor Verletzungen bieten und sich wegen ihrer hervorragenden Flexibilität dem Körper bereitwillig anschmiegen und Bewegungen des Körpers nicht behindern. Unter einem Metallringgeflecht wird ein Metallgeflecht verstanden, welches aus Metallringen aufgebaut ist, die einander wechselseitig lose umschlingen.Protective garments made of metal ring braid are worn by persons who handle tools, machines or objects which involve a particular risk of injury, in particular cuts to the body, especially the limbs, for example in meat processing in slaughterhouses, in poultry and the fishing industry, as well as when working with sharp-edged objects in the metal industry, to name but a few of the uses of such protective clothing. Metal ring braids have been well proven for such purposes so far, because they provide adequate protection against injury and readily adapt to the body because of their excellent flexibility and movements of the body hinder. Under a metal ring mesh is understood a metal braid, which is constructed of metal rings that loosely entwine each other.
Die hohe Flexibilität des Metallringgeflechts hat aber auch Nachteile, wie z.B. deutlich wird am Beispiel eines Unterarmschutzes, welcher als Stulpe an einem Handschuh befestigt sein kann. Besteht dieser Unterarmschutz aus einem Metallringgeflecht, so wird er zusammenfallen und sich im Bereich des Handgelenks zusammenschieben, wenn nicht für eine Versteifung gesorgt wird, welche ein Zusammenfallen verhindert, z.B. durch Plastik oder Metallschienen, oder wenn man den Unterarmschutz nicht bis hinter den Ellenbogen verlängert und dort mittels eines den Arm umschließenden Riemens festlegt. Beide beeinträchtigt jedoch die Beweglichkeit des Arms.However, the high flexibility of the metal ring mesh also has disadvantages such as e.g. becomes clear by the example of a forearm protection, which can be attached as a cuff on a glove. If this forearm guard consists of a metal ring mesh, it will collapse and collapse in the area of the wrist, unless stiffening is provided, which prevents collapse, e.g. by plastic or metal rails, or if you do not extend the forearm protection to behind the elbow and there by means of a strap surrounding the arm. Both, however, affect the mobility of the arm.
Um diesem Nachteil zu begegnen, ist es aus der DE 33 05 841 C2 bekannt, ein Metallringgeflecht durch Stränge aus Silikon oder Kunststoff zu versteifen, in welche Streifen des Metallringgeflechts eingebettet sind. Nachteilig hieran ist, daß derartige Silikon- oder Kunststoffstränge die Reinigung und Desinfektion der Schutzbekleidung erschweren. Hinzu kommt, daß derartige Silikon- oder Kunststoffstränge beim Arbeiten einem starkem Abrieb und Verschleiß unterworfen sind.To counteract this disadvantage, it is known from DE 33 05 841 C2 to stiffen a metal ring mesh by strands of silicone or plastic, in which strips of the metal ring mesh are embedded. The disadvantage of this is that such silicone or plastic strands make it difficult to clean and disinfect the protective clothing. In addition, such silicone or plastic strands are subjected to a strong abrasion and wear when working.
Aus der DE-OS 2 147 830 ist eine Schutzbekleidung bekannt, die ein aus metallischen Ringgliedern und kreuzförmigen Schuppengliedern bestehendes Schuppengeflecht aufweist. Durch die beschriebene Anordnung soll ein Säubern des Schuppengeflechtes erleichtert werden. Aus der DE-PS 946 523 ist eine Stechschutzschürze aus einem Metallgeflecht bekannt, in welchem Ringe aus nichtrostendem Stahl durch schuppenförmige Verbindungsglieder aus Leichtmetall miteinander verbunden sind, um das Gewicht des Metallgeflechtes zu verringern.From DE-OS 2,147,830 a protective clothing is known, which has a consisting of metallic ring links and cross-shaped scales existing scale mesh. By the described arrangement, a cleaning of the scale braid to be facilitated. From DE-PS 946 523 a stab protection apron made of a metal mesh is known, in which rings made of stainless steel by flake-shaped connecting links made of light metal are joined together to reduce the weight of the metal mesh.
Der Erfindung liegt die Aufgabe zugrunde, ein teilweise versteiftes Metallringgeflecht für Arm-, Bein- und Rumpfschutzbekleidung zu schaffen, welches leichter zu reinigen, zu desinfizieren und kostengünstig herzustellen ist.The invention has for its object to provide a partially stiffened metal ring mesh for arm, leg and torso protective clothing, which is easier to clean, disinfect and inexpensive to manufacture.
Diese Aufgabe wird gelöst durch eine Schutzbekleidung mit den im Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a protective clothing having the features specified in
Erfindungsgemäß ist vorgesehen, das Metallringgeflecht dadurch zu versteifen, daß in Teilbereichen miteinander verkettete Ringe metallisch stoffschlüssig miteinander verbunden sind. Dies kann beispielsweise durch Verschweißen oder Verlöten erreicht werden, wobei ein Verschweißen, insbesondere durch Preßschweißen, z.B. Punktschweißen oder Rollschweißen, kostengünstig und besonders bevorzugt ist. Diese Maßnahme hat den Vorteil, daß auf nichtmetallische Bestandteile der Schutzbekleidung verzichtet werden kann, wodurch sich eine leicht zu reinigende Schutzbekleidung ergibt. Derartige erfindungsgemäße Schutzbekleidung kann vorteilhaft bei hohen Temperaturen sterilisiert werden und aggressiven chemischen und mechanischen Reinigungsmitteln (Waschmittel, Desinfektionsmittel, kräftige Bürsten) ausgesetzt werden, für deren Anwendung Kunststoff zu empfindlich wäre. Insbesondere ist erfindungsgemäße Schutzbekleidung unempfindlich gegen maschinelle Reinigungsverfahren und kann beispielsweise ohne weiteres mit Hochdruckwasserstrahlgeräten und Dampfstrahlgeräten gereinigt werden. Vorteilhaft können erfindungsgemäße Teilbereiche von beliebiger Geometrie versteift werden. Dadurch wird eine günstige Anpassung an vielfältige Einsatz- und Nutzungsmöglichkeiten des Metallringgeflechts bzw. der Schutzbekleidung erreicht.According to the invention it is provided to stiffen the metal ring mesh, characterized in that in some areas chained together rings are metallically cohesively connected to each other. This can be achieved, for example, by welding or soldering, wherein welding, in particular by pressure welding, e.g. Spot welding or roll welding, inexpensive and is particularly preferred. This measure has the advantage that can be dispensed with non-metallic components of the protective clothing, resulting in an easy-to-clean protective clothing. Such protective clothing according to the invention can advantageously be sterilized at high temperatures and exposed to aggressive chemical and mechanical cleaning agents (detergents, disinfectants, strong brushes), for the use of which plastic would be too sensitive. In particular, protective clothing according to the invention is insensitive to mechanical cleaning processes and can be readily cleaned, for example, with high pressure water jet equipment and steam jet equipment. Advantageously, subregions of any geometry according to the invention can be stiffened. As a result, a favorable adaptation to a variety of uses and uses of the metal ring mesh and the protective clothing is achieved.
Ein weiterer Vorteil ist, daß sich eine metallische stoffschlüssige Verbindung miteinander verkettete Ringe mit geringem Aufwand, insbesondere ohne zusätzliche Komponenten der Schutzbekleidung, durchführen läßt, so daß die Schutzbekleidung kostengünstig gefertigt werden kann. Vorteilhaft weist derartige Schutzbekleidung eine glatte, angenehm zu tragende Oberfläche auf, insbesondere sind die versteiften Teilbereiche von geringerer Dicke als beim Stand der Technik und es tritt kein Abrieb auf.Another advantage is that a metal cohesive connection with each other chained rings with little effort, in particular without additional components of the protective clothing, perform, so that the protective clothing can be manufactured inexpensively. Advantageously, such Protective clothing on a smooth, comfortable to wear surface, in particular, the stiffened portions of lesser thickness than in the prior art and there is no abrasion.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß der metallische Stoffschluß durch Verschweißen oder Verlöten hergestellt ist. Diese Maßnahme hat den Vorteil, daß sich so eine metallische stoffschlüssige Verbindung von miteinander verketteten Ringen kostengünstig bewerkstelligen läßt.An advantageous development of the invention provides that the metallic material connection is made by welding or soldering. This measure has the advantage that it can be done inexpensively such a metallic cohesive connection of interlinked rings.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß ein Schweißpunkt jeweils vier miteinander verkettete Ringe verbindet. Diese Maßnahme hat den Vorteil, daß so ein Teilbereich mit möglichst wenigen Schweißpunkten versteift werden kann.An advantageous development of the invention provides that a welding point connects four rings linked together. This measure has the advantage that such a partial area can be stiffened with as few spot welds as possible.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die versteiften Teilbereiche streifenförmig sind. Diese Maßnahme hat den Vorteil, daß das Metallringgeflecht in Längsrichtung der Streifen nicht mehr zusammengeschoben werden kann, in Richtung quer dazu aber seine gewünschte hohe Flexibilität behält. Die Längsrichtung der Streifen verläuft am besten quer zur Längsrichtung des Geflechts. In der Laufrichtung kann das Metallringgeflecht in relativ großem Ausmaß faltenfrei zusammengeschoben werden, rechtwinklig dazu jedoch nicht. In Handschuhen ist die Laufrichtung deshalb überlicherweise so gewählt, daß sie mit der Längsrichtung der Finger übereinstimmt, so daß das Metallringgeflecht die Bewegungen der Finger bereitwillig mitmacht.An advantageous development of the invention provides that the stiffened portions are strip-shaped. This measure has the advantage that the metal ring mesh can no longer be pushed together in the longitudinal direction of the strips, but retains its desired high flexibility transversely thereto. The longitudinal direction of the strips is best transverse to the longitudinal direction of the braid. In the direction of the metal ring mesh can be pushed together wrinkle-free to a relatively large extent, but not at right angles. In gloves, therefore, the running direction is usually chosen to coincide with the longitudinal direction of the fingers, so that the metal ring weave readily participates in the movements of the fingers.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Erstreckung der versteiften Teilbereiche, insbesondere die Breite von streifenförmig versteiften Teilbereichen, mindestens das dreifache des Außendurchmessers der Ringe beträgt. Diese Maßnahme hat den Vorteil, daß sich die Belastungen, welche die versteiften Streifen auf Biegung beanspruchen auf eine größere Anzahl von Schweißpunkte verteilen, wodurch eine längere Haltbarkeit der Versteifungen erreicht wird.An advantageous development of the invention provides that the extent of the stiffened portions, in particular the width of strip-shaped stiffened portions, is at least three times the outer diameter of the rings. This measure has the advantage that the stresses that require the stiffened strips to bend on a larger number of Distribute welding points, which results in a longer durability of the stiffeners.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Teilbereiche als unterbrochene Streifen ausgebildet sind. Diese Maßnahme hat den Vorteil, daß ein Zusammenschieben des Metallringgeflechts in Längsrichtung der Streifen verhindert wird und gleichzeitig durch die Unterbrechungen der Streifen eine gewisse Flexibilität erhalten bleibt, welche den Tragekomfort der Schutzbekleidung erhöht.An advantageous development of the invention provides that the subregions are formed as interrupted strips. This measure has the advantage that a collapse of the metal ring mesh in the longitudinal direction of the strips is prevented and at the same time a certain flexibility is maintained by the interruptions of the strips, which increases the wearing comfort of the protective clothing.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß der Abstand zwischen sich nicht kreuzenden, einander benachbarten, versteiften Teilbereichen wenigstens das Doppelte des Außendurchmessers der Ringe des Metallringgeflechts beträgt. Diese Maßnahme hat den Vorteil, daß die versteiften Teilbereiche flexibel gegeneinander bewegt werden können, was den Tragekomfort der Schutzbekleidung erhält.An advantageous development of the invention provides that the distance between non-intersecting, adjacent, stiffened portions is at least twice the outer diameter of the rings of the metal ring mesh. This measure has the advantage that the stiffened portions can be flexibly moved against each other, which preserves the comfort of the protective clothing.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Außenkonturen der Schutzbekleidung stabilisiert sind. Für manche Anwendungen, wie beispielsweise Schürzen, ist es vorteilhaft, wenn die Außenkonturen, also die Ränder, versteift sind, während der innere Bereich flexibel bleibt.An advantageous development of the invention provides that the outer contours of the protective clothing are stabilized. For some applications, such as aprons, it is advantageous if the outer contours, so the edges are stiffened, while the inner region remains flexible.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die versteiften Teilbereiche ballige Strukturen stabilisieren. Diese Maßnahme hat den Vorteil, daß sich die Schutzbekleidung an Schultern oder Kopf des Trägers anpassen läßt, so daß der Tragekomfort erhöht ist.An advantageous development of the invention provides that the stiffened portions stabilize spherical structures. This measure has the advantage that the protective clothing can be adapted to the shoulders or head of the wearer, so that the wearing comfort is increased.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß je nach dem Verwendungszweck parallele streifenförmige Teilbereiche oder sich kreuzende streifenförmige Teilbereiche vorgesehen sind. Bei sich kreuzenden Strängen ist das Metallringgeflecht zweidimensional ausgesteift, so daß es in keiner Richtung ungehindert zusammengeschoben werden kann. Ein solches Geflecht eignet sich vor allem für den Schutz von Teilen des Rumpfes, z.B. als Brustschutz. Bei sich nicht kreuzenden Streifen ist das Metallringgeflecht in Richtung quer zu den Streifen zusammenschiebbar und hoch flexibel, ähnlich wie ein unversteiftes Metallringgeflecht. Ein solches Geflecht eignet sich vor allem als Arm- oder Beinschutz. Vorzugsweise verlaufen die Streifen bei einem Arm- oder Beinschutz im wesentlichen in Längsrichtung der Arme oder Beine, um ein Zusammenschieben des Geflechts längs der Arme oder Beine auch ohne besondere Festlegung am Arm oder Bein zu verhindern. Der Grad der Versteifung des Geflechts kann nach dem jeweiligen Verwendungszweck gewählt und durch Variieren des Abstandes, der Breite und der Dicke der versteiften streifenförmigen Teilbereiche in weiten Grenzen eingestellt werden.An advantageous development of the invention provides that, depending on the intended use, parallel strip-shaped partial regions or intersecting strip-shaped partial regions are provided. In intersecting strands, the metal ring mesh is stiffened two-dimensionally, so that it in no direction can be pushed together unhindered. Such a braid is particularly suitable for the protection of parts of the trunk, eg as a chest protector. For non-crossing strips, the metal ring braid is collapsible and highly flexible in the direction transverse to the strips, much like an unstiffened metal ring mesh. Such a braid is particularly suitable as arm or leg protection. Preferably, in the case of arm or leg protection, the strips extend substantially in the longitudinal direction of the arms or legs to prevent collapse of the braid along the arms or legs even without any particular attachment to the arm or leg. The degree of stiffening of the braid can be selected according to the particular application and can be set within wide limits by varying the distance, the width and the thickness of the stiffened strip-shaped sections.

Das dargestellte Metallringgeflecht 1 ist aus untereinander gleichen kreisförmigen Ringen 2 gebildet. Innerhalb des Geflechts ist jeder Ring 2 mit vier benachbarten Ringen verkettet; am Rand des Geflechts und an Nahtstellen, welche zur Anpassung der Form des Geflechts an die Kontur eines Körperteils gebildet werden, ist der Grad der Verkettung natürlich geringer.The
Figur 1 zeigt ein Stück Metallringgeflecht 1, welches in den Teilbereichen 3a, 3b, 3c dadurch versteift ist, daß in diesen Teilbereichen 3a, 3b, 3c miteinander verkettete Ringe durch Preßschweißung metallisch stoffschlüssig miteinander verbunden sind. Der Teilbereich 3a ist dabei als durchgehender Streifen ausgeführt, während die Teilbereiche 3b und 3c als unterbrochene Streifen ausgeführt sind, was den Vorteil einer größeren Flexibilität bietet. Natürlich können auch anders geformte Teilbereiche - insbesondere gebogene oder einander überkreuzende - Streifen im Metallringgeflecht 1 versteift werden. Die Verwendung streifenförmiger Teilbereiche bietet dabei den Vorteil, daß die versteifte Fläche insgesamt gering gehalten und gleichzeitig die gewünschte Versteifung der Schutzbekleidung erreicht werden kann. Eine möglichst kleine versteifte Fläche senkt die Fertigungskosten und erhöht den Tragekomfort. Die in Figur 1 gezeigten streifenförmigen Teilbereiche 3a, 3b, 3c weisen eine Breite von drei Ringdurchmessern auf. Selbstverständlich können diese Teilbereiche 3a, 3b, 3c auch schmaler oder breiter ausgeführt werden. Je breiter man sie jedoch ausführt, desto mehr büßt die Schutzbekleidung an Flexibilität ein, worunter der Tragekomfort leidet. Führt man die versteiften Teilbereiche 3a, 3b, 3c schmäler aus, so wird eine geringere Zahl von Schweißpunkten 4 entsprechend stärker belastet. Dies kann zu einem Brechen von Schweißpunkten 4 oder Metallringen 2 führen und so die Langlebigkeit der Schutzbekleidung beeinträchtigen.Figure 1 shows a piece of
Figur 2 zeigt einen Querschnitt einer Seitenansicht eines unversteiften Metallringgeflechts 1. Figur 3 zeigt einen entsprechenden Querschnitt eines versteiften Teilbereiches 3. Das Versteifen erfolgt durch Preßschweißen. Wie man durch Vergleich der Figuren 2 und 3 sieht, bewirkt dies auch, daß das Metallringgeflecht 1 in den versteiften Teilbereichen 3a, 3b, 3c merklich flacher wird.Figure 2 shows a cross section of a side view of an unstiffened
Figur 4 zeigt in einer Draufsicht und in einer entsprechenden geschnittenen Seitenansicht an einem Ausschnitt des Metallringgeflechtes 1 ein Beispiel der Verflechtung der Ringe 2. Bei einer solchen Verflechtung von Metallringen 2 werden stets vier miteinander verkettete Metallringe 2 durch einen Schweißpunkt 4 miteinander metallisch stoffschlüssig verbunden. Das Verschweißen geschieht dabei durch Preßschweißung. Selbstverständlich sind auch andere Verschweißungen oder Verlötungen denkbar. Durch Preßschweißen erreicht man jedoch kostengünstig eine dauerhafte Verbindung von jeweils vier miteinander verkettete Metallringen 2 durch einen einzigen Schweißpunkt 4. Legt man das Metallringgeflecht zum Verschweißen auf eine gewölbte Oberfläche, so lassen sich dadurch auch ballige Strukturen versteifen, so daß eine Anpassung an Kopf oder Schulter des Trägers erreicht wird. Vorteilhaft erhöht sich so der Tragekomfort.Figure 4 shows in a plan view and in a corresponding sectional side view of a section of the
Figur 5 zeigt ein Metallringgeflecht 1 mit einem versteiften Teilbereich 3d als Außenkonturstabilisierung. Vorteilhaft sind so die Außenkonturen versteift, während der innere Bereich flexibel bleibt, was beispielsweise für Schürzen günstig ist.
