Abstract

Proposed is a method of manufacturing, from a throw-away metal container, a case suitable for timepiece. The used container is reshaped longitudinally and, if necessary, also radially. A cavity capable of accommodating the mechanism is also produced by reshaping. The case described is inexpensive to manufacture since it does not require the processing of any new raw materials.

Description

Verfahren zur Herstellung eines Gehäuses für die Aufnahme eines UhrwerkesProcess for producing a housing for accommodating a clockwork
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Gehäuses für die Aufnahme eines Uhr¬ werkes.The present invention relates to a method for producing a housing for accommodating a clockwork.
Bekannt sind verschiedene Verfahren zur Herstellung von Gehäusen für Uhren aus Metall, Kunststoff, Holz, Muschel¬ material usw.Various methods for producing housings for clocks made of metal, plastic, wood, shell material, etc. are known.
**
Die vorliegende Erfindung stellt sich die Aufgabe aus einem erschöpften Gebrauchsgegenstand, nämlich einem gebrauchten Einwegbehälter aus einem metallischen Material durch Umfor¬ mung einen neuen gebrauchsfertigen Gegenstand herzustellen und damit die Umweltbelastung zu reduzieren. Diese erfindungsgemässe Aufgabe wird durch folgende Verfah¬ rensschritte gelöst:The object of the present invention is to produce a new, ready-to-use object from an exhausted commodity, namely a used disposable container made of a metallic material, and thus to reduce the environmental impact. This object according to the invention is achieved by the following process steps:
- Zusammenpressen des Behälters entlang ihrer Längsachse und gegebenenfalls in radialer Richtung auf eine vor bestimmte Diemension,Pressing the container together along its longitudinal axis and possibly in the radial direction to a predetermined dimension,
- Ausformen eines Hohlraumes zur Aufnahme des Uhrwerkes,- forming a cavity for receiving the clockwork,
- Aus- bzw. Anfor ung eines Verschlussorgans für die Verbindung mit dem Uhrwerk.- Formation or request of a locking device for connection to the clockwork.
Weitere vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen AnsprüchenFurther advantageous configurations result from the dependent claims
Das nach dem erfindungsgemässen Verfahren gefertigte Gehäuse für die Aufnahme eines Uhrwerkes weist ein Ausgangsmaterial aus metallischen Grundstoffen auf, das beispielsweise eine Getränkedose sein kann.The housing for accommodating a clockwork manufactured according to the method according to the invention has a starting material made of metallic base materials, which can be, for example, a beverage can.
Die leere Dose wird in ein Werkzeug eingespannt. Unter einer bestimmten Krafteinwirkung wird die Dose entlang ihrer Längsachse auf ein vorbestimmtes Mass zusammen¬ gedrückt. Gleichzeitig oder anschliessend an die erfolgte Verformung enlang der Längsachse der Dose kann die Form zu¬ sätzlich auch radial verkürzt werden.The empty can is clamped in a tool. Under a certain force, the can is compressed to a predetermined dimension along its longitudinal axis. At the same time or after the deformation along the longitudinal axis of the can, the shape can also be shortened radially.
Das so erhaltene Kernstück des Gehäuses wird durch Einformung einer Ausnehmung bzw. einer Vertiefung für die Aufnahme eines Uhrwerkes weitergestaltet.The core piece of the housing obtained in this way is further shaped by forming a recess or a recess for receiving a clockwork.
Zur Fixierung des Uhrwerkes mit dem geformten Gehäuseteil ist mindestens ein Verschlussorgan vorgesehen. Möglich ist die Ausbildung eines Bajonettverschlusses. Es können aber auch andere Verschlussorgane bzw. -elemente vorgesehen sein.At least one locking element is provided to fix the clockwork with the shaped housing part. It is possible to form a bayonet lock. But it can other closure members or elements may also be provided.
Zwischen dem Uhrwerk und dem Gehäuse kann eine Beschichtung vorgesehen sein. Diese kann zur Isolation zwischen Uhrwerk und Gehäuse und/oder der besseren Haftung zwischen diesen Teilen dienen.A coating can be provided between the clockwork and the housing. This can be used for insulation between the clockwork and the case and / or for better adhesion between these parts.
Durch einen weiteren Formvorgang kann eine integrierte Halterung für die Befestigung eines Armbandes in das Ge¬ häuse eingebracht werden.By means of a further molding process, an integrated holder for fastening a bracelet can be introduced into the housing.
Der Vorteil der vorgeschlagenen Fertigung eines Gehäuses besteht neben der attraktiven Erscheinungsform in der Wiederverwertung von immer kostbar werdendem Rohmaterial.In addition to the attractive appearance, the advantage of the proposed production of a housing is the recycling of raw material that is becoming ever more valuable.
Auf die erfindungsgemässe Art hergestellte Uhrgehäuse sind wirtschaftlich in der Herstellung und kommen ohne neu auf¬ zubereitenden Rohstoffen aus. Watch cases produced in the manner according to the invention are economical to manufacture and do not require any new raw materials to be reprocessed.
