Description

The invention relates to a protective glove with the in the preamble of Claim 1 specified features. Such protective gloves are known from DE 91 13 608 U1 and are e.g. worn by butchers to oppose themselves Protect cuts, punctures and cuts. Metal ring mesh for such protective gloves are usually constructed so that in them (from Seams and edges apart) each ring chained to four neighboring rings is. Such metal ring meshes are highly flexible and are easy to to protect them, their mobility. The high flexibility of the metal ring braid has the disadvantage, however, that such a glove, in contrast to one Glove made of leather or a textile fabric easily by hand slips down again if it is not tied to the wrist. The Gloves are therefore provided with a fastening strap on the wrist, which one often provided in the wrist area for gloves Slit bridges, which means putting on and taking off the glove and a wrinkle-free one Closing relieved.

It is known to produce such tapes from a thermoplastic fabric, e.g. made of a polyamide, in which the edge of the metal ring mesh in Wrist area is welded. This fabric tape is with a usual one Push button mechanism equipped to hold the glove closed.

It is also known to wrap the metal ring braid on its edge in a silicone band embedded, which is injected onto the metal ring braid.

A disadvantage of these tapes is that they are particularly wear and tear has used, difficult to clean, which is particularly the case with Dealing with food can cause problems. If the tapes are worn out, the gloves must either be thrown away or returned to the manufacturer to have new tapes attached. However, that is not very easy, because the old bands are welded to the metal ring braid or are injected.

To avoid these difficulties, gloves are already known which plastic straps are interchangeably attached. To this The purpose of the metal ring mesh is in sections in the area of the wrist double-layered to form loops through which the fastening strap can be pulled through. That makes it possible to use the tapes for the purpose of cleaning from the metal ring mesh. For daily cleaning is however, this is a tedious matter and an additional difficulty is that the loops are particularly difficult to clean.

From DE 91 13 608 U1 it is also known to use a glove to close existing perforated metal cuff. The cuff limits but wrist mobility. If you leave the cuff first start behind the wrist and extend the metal ring mesh of the Gloves up over the wrist, then you need a separate one there Closing strap with the disadvantages described above.

The present invention is based on the task of mobility to create non-restrictive protective glove, which involves cleaning of dirty gloves and replacing worn ones Closing straps has fewer problems than with known protective gloves made of metal ring mesh.

This object is achieved by a protective glove with the in claim 1 Features specified Advantageous developments of the invention are the subject of the dependent claims.

• Im Gegensatz zum Stand der Technik unterliegt das Schließband nicht höherem, sondern geringerem Verschleiß als der Handschuh im übrigen.
• Wegen des geringeren Verschleißes muß das Schließband überhaupt nie mehr ausgewechselt werden.
• Da der Handschuh einschließlich des Schließbandes aus einem Metallringgeflecht besteht, ist er viel hygienischer als bekannte Handschuhe. Da die üblicherweise aus Edelstahl bestehenden Metallringe eine glatte, porenfreie Oberfläche haben, kann der Handschuh leichter sauber gehalten werden als ein Handschuh mit einem Kunststoffband, dessen Oberfläche im Laufe der Zeit rauh und rissig wird.
• Der Handschuh kann nach Bedarf auch mit starken chemischen und mechanischen Reinigungsmitteln (Waschmittel, Lösemittel, kräftige Bürsten) behandelt werden, für deren Anwendung Kunststoff zu empfindlich wäre.
• Erfindungsgemäße Handschuhe sind unempfindlich gegen maschinelle Reinigungsverfahren.
• Erfindungsgemäße Handschuhe können auch mit Hochdruckwasserstrahlgeräten und Dampfstrahlgeräten gereinigt und ohne weiteres auch bei hohen Temperaturen sterilisiert werden.
• Schlaufen aus zweilagigem Metallringgeflecht, die sich weniger gut reinigen lassen, sind entbehrlich.
• Handschuhe mit dem erfindungsgemäßen Schließband können ganz einfach zugehalten werden. Im einfachsten Fall genügen dazu durch ein kurzes Gummiband miteinander verbundene Klammern, welche beim Fixieren von medizinischen elastischen Binden gebräuchlich sind. Diese Klammern haben Krallen, die sich kinderleicht im Metallringgeflecht verankern lassen. Solche Klammern sind ausserordentlich billig; es sind Pfennigartikel, die man, wenn sie unbrauchbar geworden sind, einfach wegwerfen kann. Es ist aber auch möglich, am Schließband selbst einen oder mehrere Krallen vorzusehen, welche zum Schließen des Handschuhs in das Metallringgeflecht eingehakt werden können. Anstelle solcher Krallen könnte man auch Stifte vorsehen, die eine Hinterschneidung, z.B. eine Taille haben und damit im Metallringgeflecht leicht verankert werden können. Wenn mehrere Krallen oder Stifte vorgesehen sind, haben sie zweckmäßigerweise eine gemeinsame starre Basis, was das Einhängen und wieder Lösen der Krallen bzw. der Stifte aus dem Metallringgeflecht erleichtert.

The glove according to the invention solves the problem in that it does not use a plastic, leather or the like closing strap, but uses a closing strap which also consists of a metal ring mesh and is linked to the glove, so that the glove and its closing strap are integrally connected to one another. This departure from the prior art eliminates the problems described at the outset, which has several advantages:

• In contrast to the prior art, the closing strap is not subject to higher, but less wear than the glove in the rest.
• Because of the lower wear, the closing strap never has to be replaced at all.
• Since the glove, including the straps, is made of a metal ring mesh, it is much more hygienic than known gloves. Since the metal rings, which are usually made of stainless steel, have a smooth, non-porous surface, it is easier to keep the glove clean than a glove with a plastic band, the surface of which becomes rough and cracked over time.
• If required, the glove can also be treated with strong chemical and mechanical cleaning agents (detergents, solvents, strong brushes), for which plastic would be too sensitive to use.
• Gloves according to the invention are insensitive to mechanical cleaning processes.
• Gloves according to the invention can also be cleaned with high-pressure water jet devices and steam jet devices and easily sterilized even at high temperatures.
• Loops made of two-layer metal ring mesh, which are less easy to clean, are unnecessary.
• Gloves with the fastening strap according to the invention can easily be locked. In the simplest case, clips connected by a short elastic band are sufficient, which are common when fixing medical elastic bandages. These brackets have claws that can be anchored very easily in the metal ring mesh. Such brackets are extremely cheap; they are penny items that can be thrown away when they have become unusable. However, it is also possible to provide one or more claws on the closing strap itself, which can be hooked into the metal ring mesh to close the glove. Instead of such claws, pins could also be provided which have an undercut, for example a waist, and can thus be easily anchored in the metal ring mesh. If a plurality of claws or pins are provided, they expediently have a common rigid base, which makes it easier to hook the claws or pins out of the metal ring mesh.

Another option is to use a metallic bracket, in particular a clip to slide laterally over the end of the fastening strap and the end of the closing strap in this way with the underlying layer of the metal ring mesh cling together.

• Die Breite des Schließbandes bleibt praktisch in jeder Situation gleich, da sich das Schließband quer zu seiner Laufrichtung praktisch nicht zusammenschieben läßt.
• Der Saum des Handschuhs im Handgelenkbereich wird dadurch stabilisiert.
• Da die Ringe in Laufrichtung des Schließbandes aufeinanderfolgend zick-zack-förmig angeordnet sind, kommt es, wenn man das Schließband um das Handgelenk herumwickelt, zu einer Verzahnung der übereinanderliegenden Lagen des Schließbandes, und diese Verzahnung verleiht dem Verschluß des Handschuhs eine ausserordentliche Zugfestigkeit, ohne daß das Schließband dazu straff gezogen werden müßte, denn es ist eine große Zahl von Metallringen, die sich schuppenartig miteinander verzahnen.
• Wegen dieser gegenseitigen Verzahnung der Ringe muß die Schließe, mit welcher man die Spitze des Schließbandes schließlich fixiert, überhaupt keine Zugbelastung aufnehmen, sondern kann sehr schwach ausgebildet sein. Ein oder zwei Stifte oder Krallen, die an der Spitze des Schließbandes angebracht sind, genügen völlig, um die Spitze des Schließbandes am darunterliegenden Abschnitt des Schließbandes festzuhalten. Geeignet ist z.B. ein Stäbchen, welches in der letzten Reihe der Metallringe an der Spitze des Schließbandes steckt und an seinen Enden je eine Kralle hat. Die Krallen haben eine zweifache Funktion, sie dienen einmal zum Fixieren der Spitze des Schließbandes auf dem darunterliegenden Abschnitt des Schließbandes und zum andern zum Festhalten des Stäbchens im Schließband. Eine solche primitive Schließe ist auch günstig aus Gründen der Hygiene, da sie keine schwer zu reinigenden Hohlräume schafft.
• Die Fähigkeit des Schließbandes zur Verzahnung mit sich selbst bleibt erhalten, wenn die Innenseite des Handschuhs nach außen gekehrt wird. Ein erfindungsgemäßer Handschuh kann deshalb unverändert wahlweise für die rechte Hand und für die linke Hand verwendet werden, wenn man ihn wendet, so daß seine Innenseite nach außen gekehrt wird und umgekehrt. Dieses Wenden ist bei einem Handschuh aus einem Metallringgeflecht wegen dessen hoher Flexibilität leicht möglich. In vorzugsweiser Weiterbildung der Erfindung sieht man deshalb an der Spitze des Schließbandes Mittel zum Fixieren der Spitze des Schließbandes vor, die sowohl bei Nutzung des Handschuhs auf der rechten Hand als auch bei Nutzung des Handschuhs der linken Hand funktionieren. Das ist z.B. dadurch möglich, daß auf beiden Seiten des Schließbandes, also auf der Oberseite und auf der Unterseite, Krallen oder Stifte vorgesehen sind, welche in die Ringe der unter ihnen befindlichen Lage des Schließbandes eindringen können. Die Stifte haben zu diesem Zweck vorzugsweise einen balligen Kopf, der sie einerseits im Metallringgeflecht festhält, andererseits aber nicht stört, soweit er nach außen absteht. Einen besonders guten Halt erreicht man mit Krallen. Damit von den Krallen keine nach außen abstehen müssen, sieht man die Krallen zweckmäßigerweise gegeneinander gerichtet auf derselben Seite der Platte vor und verkettet diese Platte mit dem Schließband, in dem man zwischen den gegeneinandergerichteten Krallen eine Reihe von Löchern vorsieht, in welche eine Reihe von Ringen an der Spitze des Schließbandes, am besten die letzte Reihe der Ringe, eingreifen. Diese Platte kann dann um die Spitze des Schließbandes herum nach Wahl auf dessen eine oder andere Seite verschwenkt werden. Weil die Krallen gegeneinander gerichtet sind, gibt es wenigstens eine, die beim Tragen an der rechten Hand oder linken Hand in das Metallringgeflecht eingehakt werden kann, um die Spitze des Schließbandes zu fixieren.

The handling of the glove according to the invention is particularly favorable if the running direction of the metal ring mesh in the closing band is perpendicular to the running direction of the metal ring mesh in the adjacent glove. In the running direction, the metal ring mesh can be pushed together to a relatively large extent without wrinkles, but not at right angles to it. In gloves, the running direction is therefore usually chosen so that it coincides with the longitudinal direction of the fingers, so that the metal ring braid willingly follows the movements of the fingers. In the closing band, the running direction is now preferably perpendicular to it, namely in the circumferential direction around the wrist. This training has additional advantages:

• The width of the closing strap remains practically the same in every situation, since the closing strap practically cannot be pushed together transversely to its running direction.
• This stabilizes the hem of the glove in the wrist area.
• Since the rings are arranged successively in a zigzag shape in the running direction of the fastening strap, if one wraps the fastening strap around the wrist, the layers of the fastening strap lying one above the other are interlocked, and this interlocking gives the glove an extraordinary tensile strength without that the closing strap would have to be pulled tight, because it is a large number of metal rings that interlock with each other like scales.
• Because of this mutual interlocking of the rings, the clasp with which the tip of the closing strap is finally fixed does not have to absorb any tensile stress at all, but can be very weak. One or two pins or claws, which are attached to the tip of the fastening strap, are sufficient to hold the tip of the fastening strap to the section of the fastening strap underneath. A stick, for example, is suitable, which is in the last row of metal rings at the tip of the locking strap and has a claw at each end. The claws have a dual function, they serve to fix the tip of the locking strap on the underlying section of the locking strap and to hold the rod in the locking strap. Such a primitive clasp is also favorable for reasons of hygiene, since it does not create cavities that are difficult to clean.
• The ability of the locking strap to interlock with itself is retained when the inside of the glove is turned outwards. A glove according to the invention can therefore be used unchanged either for the right hand and for the left hand when turned, so that its inside is turned outwards and vice versa. This turning is easily possible with a glove made of a metal ring mesh because of its high flexibility. In a preferred development of the invention, therefore, means are provided at the tip of the closing strap for fixing the tip of the closing strap, which function both when using the glove on the right hand and when using the glove of the left hand. This is possible, for example, in that claws or pins are provided on both sides of the locking strap, that is to say on the top and on the bottom, which can penetrate into the rings of the layer of the locking strap located below them. For this purpose, the pins preferably have a spherical head, which on the one hand holds them in the metal ring braid, but on the other hand does not interfere as far as it protrudes outwards. You get a particularly good hold with claws. So that none of the claws have to protrude outwards, the claws are expediently directed against one another on the same side of the plate and are linked to the plate with the locking band by providing a series of holes between the mutually directed claws, into which a series of rings intervene at the tip of the closing strap, ideally the last row of the rings. This plate can then be pivoted around the tip of the closing strap on one side or the other, as desired. Because the claws are directed towards each other, there is at least one that can be hooked into the metal ring braid when worn on the right hand or left hand in order to fix the tip of the fastening strap.

The closing strap should be so long that it can be used even with thick wrists can enclose. Is the closing strap two to three times as long as that in Hem of the glove, then there is a more intense Interlocking of the metal ring mesh with itself. The closing strap namely, when it is wrapped around the wrist, it lies on a large surface itself, which leads to a highly effective interlocking. A sufficient interlocking is already achieved when the fastening tape covers a length of a few centimeters.

There are protective gloves made of metal ring mesh that do not end at the wrist, but in a gauntlet also made of metal ring mesh continue, which can be a few centimeters long, but also almost to the elbow can be enough. With such gloves there are usually two straps provided, one in the wrist area at the transition from the actual Glove to the cuff and another closing strap at the back end of the cuff. For such a glove with cuff, the present can be further developed Invention two locking straps according to the invention made of a metal ring mesh be used. But it is also possible to only use a single shooting belt to provide which starts from the cuff, preferably from the full one Length. It could then gradually, e.g. tapering, rejuvenating and with only one clasp can be closed. Preferably, the width of the Closure band matches the length of the cuff and is replaced by at least two Closing closed. Preferably the straps and cuff have a metal ring mesh with the same running direction, which around the arm runs around.

The glove shown in Figure 1 consists of a metal ring braid, the Running direction L in the area of the palm 1 and the four fingers 2 to 5 runs in the longitudinal direction of the fingers, in the region of the thumb 6 in the latter Longitudinal direction. In the area of the outer edge of the hand there is a slot 7 in the glove provided that makes it easier to put on and take off the glove. At the Hem 8 of the braid, the running direction of which in the longitudinal direction of the fingers 2 to 5 runs, a band 9 is attached, which consists of a metal ring braid of the same structure exists, the direction of L but transverse to the direction of the Braid runs in the adjacent glove. The band 9 is with the glove braid chained; the section of the band projecting beyond the slot 7 9 is approximately twice as long as the section chained to the glove of volume 9.

The structure of the metal ring mesh in the glove and in the chain linked to it Closure band 9 is shown in FIG. 2. Apart from edges and seams, FIG each ring is linked to the braid with four neighboring rings. The running direction L is shown in Figure 2. In the running direction L, the braid is easy and collapse to less than half of its original size without drapery Length. In the direction perpendicular to the running direction L is a pushing together of the braid almost impossible

On average, the braid has the zigzag shape shown in Figure 3. From this it is clear that two with the same running direction superimposed layers of the mesh interlock with each other like scales can. This interlocking occurs when the belt 9 is closed of the glove wrapped around the wrist. The gearing works Open the glove in the opposite direction. Around the tip 10 of the closing strap 9 to fix on the underlying section of the tape 9, e.g. use the clip shown in Figure 4, which consists of two double claws 11, which are connected by a rubber band 12 and light can be hooked into the metal ring braid.

The glove shown in Figure 5 is made of a similar metal ring braid produced like that shown in Figure 1. In contrast to that closes not only a closing strap on the glove hem 8 of the glove but a cuff 13, which at each of its two ends Has closure strap 9. The running direction L of the braid in the cuff 13 and Closing straps 9 coincidently runs around the arm, transverse to the running direction in the palm of your hand. The slot 7 extends from the outer edge of the hand to the back of the cuff.

The glove shown in Figure 6 has like the glove shown in Figure 5 a cuff 13, but on which two narrow straps are not provided are, but which continues in a wide locking band 9, the Width i.w. matches the length of the cuff. The front edge of the Closure band is connected to two claws 14, which from a plate 16 Stand out sheet, which has holes 17, which is linked to the braid of the cuff 13 are and which are stamped and bent from sheet metal. The closing strap 9 is relatively short and encloses the wrist with moderate overlap. It is but it is also possible to guide the strap completely around the wrist and thereby additional protection and support of the wrist to reach.

Between the platelets 16 is the metal ring braid with a strip 18 from one Stiffened silicone plastic, which is molded onto the braid, penetrates it and covered on both sides.

Around the locking strap 9 in addition to the mutual hooking of the metal rings to secure two layers of the closing strap lying on top of each other the tip 10 of the closing strap is preferably provided with a particularly locking part. In the exemplary embodiment according to FIGS. 7 and 8 there is the closing part made of a thin metal plate, which is e.g. between 15 and 20 mm and has a series of holes 17 near one of its edges has, in particular three or four holes 17, which with the last rings on the Tip 10 of the closing strap are chained. Near the opposite Edge of the plate 16 are on this four pins 19, two on the Front and two on the back, each consisting of a spherical head 20 and a slimmer shaft 21 in contrast. The diameter the head 19 is dimensioned so that it through a ring of the metal ring braid can be inserted, after which the ring is in the area of the waist and does not easily slip back over the head 20. Since the pens are on both Side of the plate 16, the clasp can be used both when the glove is worn on the left hand as well as when the same Glove is worn on the right hand.

The embodiment of a closing part shown in FIG. 9 differs differ from the exemplary embodiment shown in FIGS. 7 and 8, that instead of the pins 19 on the edge of the plate 16, opposite the holes 17, only a hook 14 is provided, which for securing the end 10 of the locking strap 9 can be hooked into this.

The exemplary embodiment shown in FIG. 10 differs from that in FIG Figure 9 illustrated embodiment in that instead of the simple hook 14 a double hook 22 is provided, and that on the same side of the Plate 16 opposite the double hook 22 opposite one Double hook 23 is provided. Of the double hooks 22 and 23 is always only one used to close the closing strap 9, which has a double hook, when the glove is worn on the left hand, the other double hook, when the glove is worn on the right hand. In the order As shown in Figure 10, the double hook 22 is used to close. Will the Turned glove to wear it on the other hand, you also turn the plate 16, by looking at it according to FIG Tip 10 of the locking strap swings around so that most of the plate 16 rests on the metal ring braid of the fastening strap 9, after which the double hooks 22 and 23 when looking in accordance with FIG. 10 below the drawing plane are located; The double hook 23 is then different from that in Figure 10 in front of the Tip 10 of the fastening strap and can be hung in the fastening strap position, on which it rests.

With locking parts, as shown in Figures 7, 8 and 10, the inventive Glove turned around at all times and both on the right Hand as well as on the left hand, in both cases the Tip of the locking strap is properly secured in its closed position.
