Problems solved by technology

[0016] However, the purpose of the inventions or designs of Patent Documents 1-4 is to expand the operating surface, rather than to improve the sewing posture during actual sewing operations.
[0017] According to the design of Patent Document 5, a mechanism for tilting the bottom plate surface of the sewing machine body by shaking the sewing machine body is provided on the upper part of the sewing machine base, so the mechanism becomes complicated
[0018] According to the design of Patent Document 6, the bottom plate of the sewing machine can only have one inclined state, so it is difficult to sew various sewing objects, such as large flat sewing objects
[0019] According to the design of patent document 7, there is the following problem, that is, when the bottom plate surface of the sewing machine is tilted, only manual operation force can be applied on the positioning member, and other auxiliary forces cannot be applied, so it is difficult to pull out the positioning member. The positioning part is unstable when the floor surface is in an inclined state

Abstract

This sewing machine is provided with a movable leg 2 disposed at the bottom of the sewing machine and turned after slidingly operated from a storage position when tilting the bed surface 11, a torsion coil spring (an elastic member) energizing the movable leg 2 from the storage position in the direction of being turned, a locking mechanism 8 releasably retaining the movable leg 2 in the storage position, and a stopper 5 restricting the movable leg 2 at a predetermined turning position and clamping the movable leg 2 between itself and the torsional coil spring 6. The invention provides a human-friendly sewing machine enabling sewing-machine work in an easy posture by easily tilting a bed surface of the sewing machine in a single operation and stably retaining the tilted state.

Description

technical field [0001] The present invention relates to a sewing machine. Background technique [0002] Techniques for improving the operability of sewing machine operations can be broadly classified into two categories. [0003] The first technology is related to the expansion table disclosed in Patent Document 1 or 2. In this technology, in order to increase the operating surface, a portion that is generally used as a sewing machine housing is used as a workbench to improve operability. [0004] The second technique is related to the free arm shown in Patent Document 3 or 4. In this technique, when sewing a tubular object, the auxiliary base plate is removed, and the base plate surface is provided so that the tubular object can be inserted. [0005] In addition, Patent Documents 5 to 7 disclose techniques for inclining the sewing machine and its bottom plate when using the sewing machine in a free-arm state. [0006] In Patent Document 5, a mechanism for tilting the bed ...
