Yarn stand with adapter for attachment to the bobbin winder, whereby the adapter can be permanently integrated or separately designed

Abstract

Thread stand for attachment to a sewing machine, characterized by - an adapter for mounting on the device for attaching a bobbin, - the adapter is designed either as a separate component or as an integral part of the yarn stand, - vertical storage of a yarn reel, - a first thread guide for vertically pulling the sewing thread upwards, - as well as additional thread guides that guide the thread back to spool height, with the lowest thread guide being positioned lower than conventional thread stands in order to compensate for the height difference caused by the alternative mounting point.

Description

Technical description

[0001] The invention relates to a thread stand with integrated thread guides and an adapter for attachment to the bobbin winder of household and industrial sewing machines. The aim of the invention is to provide an alternative method of attachment, particularly useful when the vertical thread stand of the sewing machine is unavailable or unsuitable. State of the art:

[0002] Previously known thread stands are typically mounted on the existing vertical spool holder of a sewing machine. The thread is drawn vertically via integrated guides and returned to the spool height. However, this solution is not compatible with all sewing machines or practical in certain work situations.

[0003] An earlier embodiment of this invention is protected by utility model DE20 2025 000 998 U1 (Michael Weuthen). This is based on attaching the yarn stand to the vertical yarn spool holder. The present invention differs significantly in that it is attached to the bobbin winding device using an adapter, which is either separately formed or integrated into the yarn stand, and in that it features an adapted thread guide to compensate for the changed installation height. Object of the invention:

[0004] The invention aims to provide a yarn stand that can be attached to the bobbin winder. This involves using an adapter that is placed on the bobbin winder's spool spindle instead of a conventional bobbin. The yarn stand is mounted on it, with the adapter being designed either as a separate part or as an integral part of the yarn stand. Solution:

[0005] The thread stand is connected to or has an integrated adapter, which is placed on the bobbin holder. The thread spool is stored vertically. The thread is drawn vertically upward through a first thread guide and then guided back to the spool height through two additional thread guides. To compensate for the height difference caused by the lower mounting point on the bobbin winder, the lowest thread guide in this version is positioned lower than in the previous version. Advantages of the invention: • Mounting option also for machines without suitable spool holder • Stable, constant tension thread feed through optimized thread guide • Compensation of the height by adapted thread guide • Easy retrofitting without permanent changes to the sewing machine • Compatibility with different machine types • Adapter solution can be implemented flexibly - integrated or separate List of reference symbols
