However, this kind of conventional example as mentioned above,
As mentioned above, the lower differential feed sewing machine was designed to be manufactured by adding a lower differential mechanism to a standard lockstitch sewing machine, so the lower differential mechanism was not required. Even in the case of a standard lockstitch sewing machine that does not have the above-mentioned additional changes, for example, a branch space for driving the sub-feed adjuster B from the middle of the connecting rod C of the main feed adjuster A is prepared in advance. Since it was necessary to make preparations, it was difficult to design the main feed adjustment body A alone in the most rational manner, and therefore, as shown in FIG. 2, the main feed adjustment body A was
The connecting rod C is disposed on the vertical feed shaft 2 side, which is far away from the main shaft 1 and the main feed shaft 4, and therefore the overall length of the connecting rod C is long, requiring space. Along with this, high accuracy is required in the machining of each component in order to maintain the accuracy of the motion trajectory and prevent the generation of vibrations, and there is also a disadvantage in that it is disadvantageous in terms of ease of assembly and maintainability. .

た下差動送り機構の提供を目的にしている。 The present invention was developed by focusing on the problems of the conventional models as described above, and enables a rational design that requires a small space for a standard lockstitch sewing machine. The object of the present invention is to provide a lower differential feed mechanism to which an auxiliary feed mechanism can be easily added when converting to a feed sewing machine.

As explained above, according to the present invention, the main feed adjustment body of the differential feed mechanism is disposed on the main horizontal feed shaft side, and the sub feed adjustment body is disposed on the vertical feed shaft side. In mass-produced standard lockstitch sewing machines, which are the base of lower differential feed sewing machines, the main feed adjustment body can be designed rationally and compactly, so the accuracy required for parts processing is lower than before. The ease of assembly and maintenance has also been improved. Additionally, it has become easier to add and change the sub-feed mechanism when converting to a lower differential feed sewing machine type.
