Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a sewing thread guide mechanism for a toy sewing machine that can reliably guide sewing thread wound around a thread winder to the needle hole of a needle.

(Prior art and its problems) Conventionally, as a sewing thread guide mechanism for general sewing machines,
As shown in Japanese Utility Model Application No. 50-102548, there is known a device in which the sewing thread is passed through a small hole formed in the needle bar thread hook. However, such a thread guide mechanism cannot be used in toy sewing machines. This is because toy sewing machines are mainly used by children.
This is because detailed work such as threading a thread through a small hole is extremely troublesome for small children. By the way, if the mechanism was made too simple so that it could be used by children, the sewing thread would easily come off, which could result in poor sewing.

(Problem to be solved by the invention) The present invention has been made in view of the above-mentioned points of view, and is particularly directed to a toy sewing machine that can guide sewing thread into the needle hole of a needle with a simple structure. The purpose of this paper is to propose a sewing thread guide mechanism.

(Technical means to solve the problem) As a technical means to solve the above problem,
The sewing thread guide mechanism of the toy sewing machine according to the present invention is as follows:
In a toy sewing machine that sews cloth material on a sewing table by moving the needle up and down from the needle drop part toward the sewing table,
It is characterized by having the following requirements.

(a) A guide groove that opens laterally and guides the sewing thread inserted from the thread winder into the needle hole is provided on one side of the support piece provided perpendicularly from the lower surface of the needle drop section.

(b) The guide groove is formed between upper and lower supporting parts that protrude laterally, and the lower supporting part is formed to protrude longer in the lateral direction than the upper supporting part.

(c) The guide groove is formed near the needle and at approximately the same height as the needle hole.

(Operations and Effects of the Invention) According to the above structure, when guiding the sewing thread, it is only necessary to hang the sewing thread in the guide groove, so that even children can handle it very easily.

Furthermore, since the guide grooves are formed near the needle at almost the same height, the disturbance caused by the movement of the thread as the needle moves up and down is small, so the sewing thread can be guided well. .

Furthermore, since the lower support portion of the guide groove protrudes laterally, the sewing thread is less likely to come off the guide groove.

Moreover, since these effects can be achieved with an extremely simple structure, large practical effects can be obtained at low cost.
