Abstract
Description
Die Erfindung betrifft ein Armband, insbesondere ein Schmuck- oder Uhrarmband, mit einem Bandkörper aus Elastomer, sowie mehrere Varianten zum Herstellen des Armbands.The invention relates to a bracelet, in particular a jewelry or watch strap, with a band body made of elastomer, as well as several variants for producing the bracelet.
Es besteht das Bestreben, Armbänder, wie Schmuck- bzw. Uhrarmbänder, mit einem hohen Tragekomfort auszustatten, und dazu ein robustes, pflegeleichtes Material zu verwenden, das in zahlreichen Varianten gestaltet werden kann.There is an effort to provide bracelets, such as jewelry or watch straps, with a high level of comfort, and to use a robust, easy-care material that can be designed in numerous variants.
Diese Aufgabe wird bei einem Armband der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, dass der Bandkörper aus einem Grundkörper und zumindest einem Einsatzkörper besteht, die durch ein in der Gummiindustrie gebräuchliches Verbindungsverfahren, beispielsweise durch Umspritzgießen oder Pressen, miteinander verbunden sind.This object is achieved in a bracelet of the type described above according to the invention that the band body consists of a base body and at least one insert body, which are connected by a common in the rubber industry connection method, for example by extrusion coating or pressing.
Beim Umspritzgießen wird ein Kunststoff, beispielsweise ein Elastomer, mithilfe eines Kolbens durch eine Öffnung in einen als Kavität bezeichneten inneren Hohlraum eines verschließbar geteilten ersten Werkzeugs gedrückt. Dieser Hohlraum im Inneren des Werkzeugs weist eine Negativform zumindest eines Teils eines ersten Bandkörpers auf. Ein zweiter Bandkörper, der mit einem zweiten, ebenfalls verschließbar geteilten Werkzeug hergestellt wurde, wird in einem eigens dafür vorgesehenen Abschnitt der Kavität des ersten Werkzeugs umgesetzt bzw. eingelegt. Mit dem durch eine Öffnung des ersten Werkzeugs eingebrachten Elastomer, das sich im verbleibenden Hohlraum verteilt, wird der eingelegte zweite Bandkörper umspritzt.In the case of extrusion coating, a plastic, for example an elastomer, is pressed by means of a piston through an opening into an inner cavity, referred to as a cavity, of a closably divided first tool. This cavity in the interior of the tool has a negative mold of at least part of a first band body. A second band body, which was produced with a second, likewise closable split tool, is implemented or inserted in a specially provided section of the cavity of the first tool. With the introduced through an opening of the first tool elastomer, which is distributed in the remaining cavity, the inserted second band body is encapsulated.
Auch beim Pressen entsteht - gleich wie beim Umspritzgießen - der jeweils andere Bandkörper im Inneren des verschließbaren Werkzeugs. Es ist nicht nötig, dass die beiden Bandkörper bereits vor dem Verbinden vorhanden bzw. fertig gestellt sind. Unterschiedlich ist lediglich die Einbringung des für die Herstellung des jeweils anderen Bandkörpers benötigten Materials in das Werkzeug. Beim Pressen wird das Material händisch in Form von Streifen oder Sheets in das offene Werkzeug gelegt. Beim Schließen des Werkzeugs erfolgt durch Pressen ein Druckaufbau und das eingelegte Material verteilt sich im Hohlraum des Werkzeugs.Also when pressing arises - just as in Umspritzgießen - the other band body inside the lockable tool. It is not necessary that the two tape bodies are already present or completed before the connection. The only difference is the introduction of the material required for the production of the respective other belt body into the tool. During pressing, the material is laid by hand in the form of strips or sheets in the open tool. When closing the tool, a pressure build-up takes place by pressing and the inserted material is distributed in the cavity of the tool.
Musterförmige Vertiefungen oder Ausnehmungen an der Oberfläche der Bandkörper werden dabei vom Werkzeug auf das Armband übertragen. Je nach Gestaltungsvorgaben können auch mehr als zwei Bandkörper durch Umspritzen, Pressen oder einem anderen Verbindungsverfahren miteinander verbunden werden.Pattern-shaped recesses or recesses on the surface of the tape body are thereby transferred from the tool to the bracelet. Depending on the design specifications, more than two tape bodies can be connected to each other by molding, pressing or another connection method.
Aus dem Stand der Technik sind zahlreiche Anwendungen von in der Gummiindustrie gebräuchlichen Verbindungsverfahren, wie beispielsweise dem Umspritzgießverfahren oder dem Pressverfahren, zur Verbindung zweier oder mehrerer Kunststoffkomponenten bekannt. Eine Anwendung eines derartigen Verbindungsverfahrens als Teil eines Herstellungsverfahrens für ein Armband mit Bandkörper aus Elastomer, insbesondere ein Schmuck- oder Uhrarmband, ist bisher nicht bekannt.Numerous applications of joining methods commonly used in the rubber industry, such as, for example, the overmold casting method or the pressing method, for joining two or more plastic components are known from the prior art. An application of such a bonding method as part of a manufacturing process for a bracelet with elastomeric band body, in particular a jewelry or watch band, is not yet known.
Zweckmäßig sind bei einem erfindungsgemäßen Armband ein Grundkörper und zumindest ein Einsatzkörper aus demselben Material hergestellt. Damit kann das Armband mit homogenen Stoffeigenschaften, beispielsweise mit gleichmäßigen Dehnungseigenschaften, von Grundkörper und zumindest einem Einsatzkörper ausgestattet werden.Appropriately, a base body and at least one insert body are made of the same material in a bracelet according to the invention. Thus, the bracelet with homogeneous material properties, for example, with uniform elongation properties of body and at least one insert body can be equipped.
In einer vorteilhaften Ausgestaltungsform sind der Grundkörper und zumindest ein Einsatzkörper eines erfindungsgemäßen Armbands unterschiedlich gefärbt. Es ist auch denkbar, zur besonderen Gestaltung eines Armbands mehrere Einsatzkörper vorzusehen, die jeweils unterschiedlich gefärbt sind.In an advantageous embodiment, the base body and at least one insert body of a bracelet according to the invention are colored differently. It is also conceivable to provide for the particular design of a bracelet several insert body, which are each colored differently.
In einer bevorzugten Ausführungsform der Erfindung weist ein Armband zumindest eine Ausnehmung auf, die beispielsweise als Schriftzug oder als eine geometrische Form zumindest in einem Abschnitt des zumindest einen Einsatzkörpers ausgebildet ist, wobei durch diese Ausnehmung des Einsatzkörpers hindurch der Grundkörper des Armbands ersichtlich ist. Besonders effektvoll erscheint eine solche Ausnehmung in einem Einsatzkörper, wenn ein darunter liegender Grundkörper - oder in einer denkbaren Variante mit mehr als einem Einsatzkörper ein weiterer, darunter liegender Einsatzkörper - anders gefärbt oder aus einem anderen Material hergestellt ist.In a preferred embodiment of the invention, a bracelet has at least one recess, which is formed, for example, as a lettering or as a geometric shape at least in a portion of the at least one insert body, through this recess of the insert body through the main body of the bracelet is visible. Such a recess in an insert body appears to be particularly effective if an underlying base body - or in a conceivable variant with more than one insert body another, underlying insert body - colored differently or made of a different material.
Gemäß einem weiteren Merkmal der Erfindung ist ein Armband mit zumindest einem Insert, beispielsweise mit einem Schmuckstück, gestaltet, das in Ausnehmungen zumindest eines Abschnittes des Einsatzkörpers befestigt ist. Durch die Ausgestaltung beispielsweise mit einem Schmuckstück wird das Armband veredelt. Bei geeigneter Anordnung des Inserts, das in einem Einsatzkörper befestigt ist und vorzugsweise gemeinsam mit dem Einsatzkörper vom Grundkörper mit umspritzt wird, lässt sich ein unbeabsichtigtes Herausfallen des Inserts aus dem Armband verhindern.According to a further feature of the invention, a bracelet with at least one insert, for example with a piece of jewelry designed, which is fixed in recesses of at least a portion of the insert body. The design, for example, with a piece of jewelry, the bracelet is finished. With a suitable arrangement of the insert, which is fixed in an insert body and preferably together with the insert body Is encapsulated by the body with an unintentional falling out of the insert from the bracelet can be prevented.
Eine Variante der Erfindung sieht vor, dass bei einem Armband zwischen dem Grundkörper und dem Einsatzkörper ein flacher Zwischenkörper vorgesehen ist, wobei der Zwischenkörper, beispielsweise ein Abschnitt eines Gewebes, insbesondere eines Gewebes aus Carbonfasern, durch Umspritzgießen oder Pressen des Grundkörpers um den Einsatzkörper in seiner Lage fixiert ist. Der Zwischenkörper kann aus unterschiedlichsten Materialien beschaffen sein. Besonders geeignet sind beispielsweise textile Gewebe oder Gewebe aus Carbonfasern, die als Zwischenkörper verwendet werden. Zum Schutz vor Abrieb und Verschmutzung ist der Zwischenkörper zumindest teilweise bedeckt vom Einsatzkörper im Inneren des Armbands angeordnet.A variant of the invention provides that in a bracelet between the base body and the insert body, a flat intermediate body is provided, wherein the intermediate body, for example, a portion of a fabric, in particular a fabric of carbon fibers, by extrusion molding or pressing of the base body to the insert body in his Location is fixed. The intermediate body can be made of a variety of materials. For example, textile fabrics or fabrics made of carbon fibers, which are used as intermediate bodies, are particularly suitable. To protect against abrasion and contamination, the intermediate body is at least partially covered by the insert body in the interior of the bracelet.
Vorteilhaft ist bei einem solchen erfindungsgemäßen Armband der Zwischenkörper mit dem Einsatzkörper und/oder Grundkörper durch eine stoff- oder formschlüssige Verbindung, beispielsweise durch Verkleben oder Vulkanisieren, miteinander verbunden. Damit wird ein Verrutschen des flachen Zwischenkörpers während der Herstellung des Armbands vermieden und der Zwischenkörper kann plan anliegend an einen Bandkörper in seiner Lage fixiert werden.Advantageously, in such a bracelet according to the invention the intermediate body with the insert body and / or base body by a material or positive connection, for example by gluing or vulcanization, connected to each other. In order for slippage of the flat intermediate body during the manufacture of the bracelet is avoided and the intermediate body can be fixed plan fitting to a band body in position.
Zweckmäßig ist der Zwischenkörper eines erfindungsgemäßen Armbands zumindest teilweise sichtbar zwischen Einsatzkörper und Grundkörper angeordnet, wobei beispielsweise der Einsatzkörper zumindest abschnittsweise aus einem transparenten Material besteht oder mit Ausnehmungen versehen ist, innerhalb derer der Zwischenkörper ersichtlich ist. Damit trägt der Zwischenkörper wesentlich zur effektvollen Gestaltung des Armbands bei.Suitably, the intermediate body of a bracelet according to the invention is at least partially visible between the insert body and the base body, for example, the insert body at least partially consists of a transparent material or is provided with recesses within which the intermediate body is visible. Thus, the intermediate body contributes significantly to the effective design of the bracelet.
Ein vorteilhaftes Verfahren zum Herstellen eines erfindungsgemäßen Armbands erfordert den Einsatz von mindestens zwei formgebenden Werkzeugen, wobei ein Einsatzkörperwerkzeug eine Negativform des Einsatzkörpers aufweist, mit dem der Einsatzkörper vorzugsweise durch Spritzgießen erhalten wird, in dem der Einsatzkörper erforderlichenfalls auch vulkanisiert wird. Danach wird der Einsatzkörper dem Einsatzkörperwerkzeug entnommen und anschließend in einer dafür vorgesehenen Ausnehmung des Grundkörperwerkzeugs, welche die Negativform des Einsatzkörpers aufweist, eingelegt. Das Grundkörperwerkzeug, das ebenso wie das Einsatzkörperwerkzeug vorzugsweise teilbar ausgestaltet ist und geöffnet und wiederverschlossen werden kann, weist in seinem Inneren neben der Ausnehmung in Negativform des Einsatzkörpers auch noch zumindest einen Hohlraum mit einer Negativform des Grundkörpers auf, wobei der Einsatzkörper im Grundkörperwerkzeug mit dem Grundkörper durch Umspritzgießen oder einem anderen aus der Gummiindustrie bekannten Verbindungsverfahren, beispielsweise durch Pressen, verbunden wird.An advantageous method for producing a bracelet according to the invention requires the use of at least two shaping tools, wherein an insert body tool has a negative mold of the insert body, with which the insert body is preferably obtained by injection molding, in which the insert body is also vulcanized if necessary. Thereafter, the insert body is removed from the insert body tool and then inserted into a recess provided for this purpose of the main body tool, which has the negative mold of the insert body. The basic body tool, which, like the insert body tool, is preferably designed to be divisible and can be opened and resealed, also has, in its interior, the recess in the negative mold of the insert body nor at least one cavity with a negative mold of the base body, wherein the insert body in the main body tool with the main body by extrusion molding or other known from the rubber industry bonding method, for example by pressing, is connected.
Zweckmäßig ist bei einem Verfahren zum Herstellen eines Armbands das Einsatzkörperwerkzeug mit einer zumindest teilweise umlaufenden Dichtlippe berandet, die während des Umspritzgießens oder Pressens des Grundkörpers um den Einsatzkörper ein Verschwimmen des Einsatzkörpers verhindert. Diese Ausführung eines Einsatzkörperwerkzeugs mit Dichtlippen, die konstruktiv am Rand der Negativform des Einsatzkörpers vorgesehen sind, um ein Verschwimmen oder Ineinanderfließen von Einsatzkörper und Grundkörper zu verhindern, kann sinngemäß auch am Grundkörperwerkzeug, bei dem ebenfalls Dichtlippen zur sauberen Trennung der Konturen von Einsatzkörper und Grundkörper vorhanden sein können, ausgeführt sein. Besonders vorteilhaft sind Dichtlippen an einem oder an beiden Werkzeugen an den Verbindungsstellen unterschiedlich gefärbter Materialien für den Einsatzkörper und den Grundkörper vorgesehen. Damit werden besonders saubere Konturen der unterschiedlich gefärbten Bandkörper erzielt und das mehrfarbige Armband erscheint sehr hochwertig.In a method for producing a bracelet, the insert body tool is expediently bounded by an at least partially encircling sealing lip which prevents bluffing of the insert body during the encapsulation casting or pressing of the main body about the insert body. This embodiment of an insert body tool with sealing lips, which are structurally provided on the edge of the negative mold of the insert body to prevent blurring or intermingling of insert body and body can, mutatis mutandis, on the base body tool, also provided in the sealing lips for clean separation of the contours of insert body and body be executed. Particularly advantageous sealing lips are provided on one or both tools at the junctions of differently colored materials for the insert body and the body. Thus, particularly clean contours of the differently colored band body are achieved and the multi-colored bracelet appears very high quality.
In einer zweckmäßigen Variante eines Herstellungsverfahrens für ein erfindungsgemäßes Armband werden mindestens zwei formgebende Werkzeuge eingesetzt, wobei das Einsatzkörperwerkzeug eine Negativform des Einsatzkörpers aufweist, wobei vorzugsweise Ausnehmungen zur Aufnahme zumindest eines Inserts, beispielsweise eines Schmuckstückes, im Einsatzkörper bereits im Einsatzkörperwerkzeug berücksichtigt sind. Der Einsatzkörper wird im Einsatzkörperwerkzeug vorzugsweise durch Spritzgießen erhalten und erforderlichenfalls im Einsatzkörperwerkzeug auch vulkanisiert. Anschließend wird der Einsatzkörper dem Einsatzkörperwerkzeug entnommen und in ein Grundkörperwerkzeug, welches eine Negativform des Einsatzkörpers und zumindest eines Inserts sowie eine Negativform des Grundkörpers aufweist, übertragen, und das zumindest eine Insert, beispielsweise ein Schmuckstück, anschließend in die vorgesehenen Ausnehmungen des Einsatzkörpers eingeführt und darin befestigt. Der Einsatzkörper und das zumindest eine Insert werden daraufhin im Grundkörperwerkzeug mit dem Grundkörper durch Umspritzgießen oder einem anderen aus der Gummiindustrie bekannten Verbindungsverfahren, beispielsweise durch Pressen, verbunden, sodass das zumindest eine Insert in seiner Lage zwischen dem Grundkörper und dem Einsatzkörper fixiert ist. Auch sinngemäße Varianten des Herstellungsverfahrens, bei denen beispielsweise mehrere Einsatzkörper gemeinsam mit einem Grundkörper verbunden werden und zumindest ein Insert in Ausnehmungen zumindest eines von mehreren Einsatzkörper befestigt ist, sind umfasst.In an expedient variant of a manufacturing method for a bracelet according to the invention at least two shaping tools are used, wherein the insert body tool has a negative mold of the insert body, wherein preferably recesses for receiving at least one insert, for example a piece of jewelry, are already taken into account in the insert body tool in the insert body. The insert body is preferably obtained in the insert body tool by injection molding and, if necessary, also vulcanized in the insert body tool. Subsequently, the insert body is removed from the insert body tool and transferred into a base body tool, which has a negative mold of the insert body and at least one insert and a negative mold of the base body, and the at least one insert, such as a piece of jewelry, then inserted into the provided recesses of the insert body and therein attached. The insert body and the at least one insert are then connected in the main body tool with the base body by extrusion molding or other known from the rubber industry bonding method, for example by pressing, so that the at least one insert is fixed in position between the base body and the insert body. Also analogous variants of the manufacturing process in which, for example, several insert body are connected together with a body and at least one Insert in recesses at least one of several insert body is attached are included.
In einer weiteren Ausführungsform zur Lösung der erfindungsgemäßen Aufgabe ist ein Verfahren zum Herstellen eines Armbands dadurch gekennzeichnet, dass mindestens zwei formgebende Werkzeuge eingesetzt werden, wobei das Einsatzkörperwerkzeug eine Negativform des Einsatzkörpers aufweist, mit dem der Einsatzkörper vorzugsweise durch Spritzgießen erhalten wird, wobei der Einsatzkörper erforderlichenfalls im Einsatzkörperwerkzeug auch vulkanisiert wird, worauf anschließend zumindest ein Abschnitt eines flachen Zwischenkörpers an dem Einsatzkörper angeordnet wird. Daraufhin wird der Einsatzkörper samt dem daran angeordneten Zwischenkörper dem Einsatzkörperwerkzeug entnommen und in ein Grundkörperwerkzeug, welches eine Negativform des Einsatzkörpers, des Zwischenkörpers sowie des Grundkörpers aufweist, übertragen.In a further embodiment for achieving the object according to the invention, a method for producing a bracelet is characterized in that at least two shaping tools are used, wherein the insert body tool has a negative mold of the insert body, with which the insert body is preferably obtained by injection molding, wherein the insert body, if necessary in the insert body tool is also vulcanized, whereupon at least a portion of a flat intermediate body is arranged on the insert body. Then the insert body together with the intermediate body arranged thereon is removed from the insert body tool and transferred into a base body tool, which has a negative mold of the insert body, of the intermediate body and of the main body.
Eine vorteilhafte Variante des Herstellungsverfahrens sieht vor, dass Einsatzkörper und Zwischenkörper bereits im ersten Herstellungsschritt miteinander verbunden werden: der Zwischenkörper wird in das Einsatzkörperwerkzeug eingelegt und mit dem Einsatzkörper hinterspritzt. Anschließend können Zwischenkörper und Einsatzkörper als eine Einheit dem Einsatzkörperwerkzeug entnommen und in das Grundkörperwerkzeug übertragen werden.An advantageous variant of the production method provides that insert body and intermediate body are already connected to each other in the first manufacturing step: the intermediate body is inserted into the insert body tool and back-injected with the insert body. Subsequently, intermediate body and insert body can be removed as a unit of the insert body tool and transferred into the main body tool.
Der Einsatzkörper samt dem Zwischenkörper werden im Grundkörperwerkzeug mit dem Grundkörper durch Umspritzgießen oder einem anderen aus der Gummiindustrie bekannten Verbindungsverfahren, beispielsweise durch Pressen, verbunden, sodass der zumindest eine Zwischenkörper in seiner Lage zwischen dem Grundkörper und dem Einsatzköper fixiert ist. In dieser Variante des Herstellungsverfahrens wird zuerst der Einsatzkörper hergestellt, an den zumindest ein Abschnitt eines Zwischenkörpers angeordnet, beispielsweise angeklebt oder anderwärtig befestigt, wird, und danach Einsatzkörper und Zwischenkörper gemeinsam mit dem Grundkörper verbunden werden.The insert body together with the intermediate body are connected in the main body tool with the base body by extrusion molding or other known from the rubber industry bonding method, for example by pressing, so that the at least one intermediate body is fixed in position between the base body and the insert body. In this variant of the production method, first the insert body is produced, to which at least a portion of an intermediate body is arranged, for example glued or otherwise secured, and then the insert body and intermediate body are connected together with the main body.
Je nach Gestaltung des Armbands ist auch eine umgekehrte Herstellungsvariante denkbar, bei der zweckmäßig zuerst der Grundkörper vorzugsweise durch Spritzgießen im Grundkörperwerkzeug erhalten wird, dieser erforderlichenfalls im Grundkörperwerkzeug auch vulkanisiert wird, worauf anschließend zumindest ein Abschnitt eines flachen Zwischenkörpers an den Grundkörper beispielsweise durch Ankleben angeordnet wird.Depending on the design of the bracelet, a reverse production variant is also conceivable in which the basic body is preferably first obtained by injection molding in the base body tool, if necessary also vulcanized in the base body tool, whereupon at least a portion of a flat intermediate body is arranged on the base body, for example by gluing ,
Auch in dieser umgekehrte Herstellungsvariante kann es von Vorteil sein, wenn Grundkörper und Zwischenkörper bereits im ersten Schritt miteinander verbunden werden: der Zwischenkörper wird in das Grundkörperwerkzeug eingelegt und mit dem Grundkörper hinterspritzt. Anschließend können Zwischenkörper und Grundkörper als eine Einheit dem Grundkörperwerkzeug entnommen und in das Einsatzkörperwerkzeug übertragen werden.Also in this reverse production variant, it may be advantageous if the base body and intermediate body are already connected to one another in the first step: the intermediate body is inserted into the basic body tool and back-injected with the base body. Subsequently, the intermediate body and the base body can be removed as a unit from the main body tool and transferred into the insert body tool.
Der Grundkörper wird danach samt dem Zwischenkörper dem Grundkörperwerkzeug entnommen und in ein Einsatzkörperwerkzeug, welches eine Negativform des Einsatzkörpers, des Zwischenkörpers sowie des Grundkörpers aufweist, übertragen. Im Einsatzkörperwerkzeug werden der Grundkörper samt dem daran angeordneten Zwischenkörper mit dem Einsatzkörper durch Umspritzgießen oder einem anderen aus der Gummiindustrie bekannten Verbindungsverfahren, beispielsweise durch Pressen, verbunden, sodass der zumindest eine Zwischenkörper in seiner Lage zwischen dem Grundkörper und dem Einsatzköper fixiert ist.The main body is then removed together with the intermediate body of the main body tool and in an insert body tool, which has a negative mold of the insert body, the intermediate body and the base body transmitted. In the insert body tool, the main body together with the intermediate body arranged thereon are connected to the insert body by extrusion molding or another connection method known from the rubber industry, for example by pressing, so that the at least one intermediate body is fixed in its position between the main body and the insert body.
Abschließend ist vorteilhaft bei einem Verfahren zum Herstellen eines erfindungsgemäßen Armbands vorgesehen, dass der Bandkörper nach der Herstellung, beispielsweise nach dem Spritzgießen, mit zumindest einem Zerspanwerkzeug, beispielsweise einem Fräser oder einem Bohrer, und/oder einem Stanzwerkzeug nachbearbeitet wird, um beispielsweise Bohrungen zur Aufnahme eines Bügels einer Schließe anzubringen. Auch Anspritzpunkte, die gegebenenfalls vom Umspritzgießen des Grundkörpers um den Einsatzkörper noch ersichtlich sind und von der Oberfläche das Armbands abstehen, können erforderlichenfalls nachbearbeitet werden.Finally, it is advantageous in a method for producing a bracelet according to the invention provided that the tape body after manufacture, for example, after injection molding, with at least one cutting tool, such as a cutter or a drill, and / or a punching tool is reworked, for example, holes for receiving a strap of a clasp to attach. Injection points, which may still be visible from the injection molding of the base body around the insert body and protrude from the surface of the bracelet, can be post-processed if necessary.
