Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a bobbin for winding a thread used for various kinds of sewing and embroidery, and more specifically to a bobbin in which the type and length of the thread are displayed on the top of the bobbin main body.

[0002]

[Prior art]

 The bobbin for winding the thread used for sewing and embroidery on the sewing machine has a cylindrical base part on the lower end of which is provided with a tapering base part that spreads downwards, so that the base part can be stably and independently supported. At the same time, the bobbin body has a structure in which the thread is wound to a predetermined length.

In the bobbin as described above, it is necessary to display the thickness and length of the wound thread, the type such as the color number, and the product name.

Conventionally, in the above display, a display sheet in which necessary items are described is attached to the inner surface side of the base portion.

[0005]

[Problems to be solved by the device]

 However, the structure in which the display sheet is attached to the inner surface of the base member cannot be seen from the outside, and if it is necessary to check the display content during use, it must be removed from the inserted shaft and turned over. There is the inconvenience of not becoming.

Further, since the bobbin main body of the conventional bobbin has a straight cylindrical shape, the inner diameter is larger than the mounting shaft of the sewing machine, and the bobbin is shaken depending on the thickness of the thread when the thread is pulled out. There is a problem that it will occur.

Therefore, the object of the present invention is to solve the above-mentioned problems, so that the displayed contents can be easily confirmed from the outside of the bobbin, and the deflection of the bobbin mounted on the sewing machine mounting shaft can be prevented. To provide a bobbin that does not occur.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a display sheet in which a shaft insertion hole is formed in the center of the top wall provided at the upper end of the bobbin main body, and the thread necessary items are described on the top surface of the top wall. This is the structure that is pasted.

[0009]

[Action]

 Since a display sheet is attached to the top surface of the top wall of the bobbin main body, the displayed contents can be easily checked from the outside of the bobbin, and the shaft insertion hole on the top wall fits the mounting shaft of the sewing machine. It is possible to prevent the bobbin from swinging when the thread is pulled out.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the bobbin 1 includes a bobbin body 2 formed in a cylindrical shape and a base portion 3 having a downwardly widened taper formed continuous with a lower end portion of the bobbin body 2, and a top wall 4 formed at an upper end portion of the bobbin body 2. At the center of the top wall 4, there is formed a shaft insertion hole 5 having an inner diameter to which the mounting shaft of the sewing machine fits.

In the bobbin 1, the bobbin main body 2, the base portion 3 and the top wall 4 are integrally molded of synthetic resin, and the display sheet 6 is attached to the upper surface of the top wall 4.

The display sheet 6 has an outer diameter substantially equal to that of the top wall 4, a through hole 7 corresponding to the shaft insertion hole 5 is provided at the center, and the bobbin 1 is wound on the surface thereof. Necessary items such as the thickness and length of the thread A, the type such as the color number, and the product name are described.

Although not shown, a plurality of grooves or protrusions may be provided on the outer peripheral surface of the bobbin main body 2 to obtain an effect of preventing the wound yarn A from coming off.

The bobbin of the present invention has the above-mentioned structure, and the thread A having a predetermined length is wound around the outer circumference of the bobbin main body 2, and the display sheet 6 indicating the necessary items of the thread A is provided on the upper surface of the top wall 4. When the product is used, the bobbin body 2 is inserted into the attachment shaft of the sewing machine, and the shaft insertion hole 5 of the top wall 4 is inserted into the attachment shaft and arranged in an upright position to allow the thread A to be pulled out. .

When the bobbin 1 is used as described above, in order to confirm the necessary items of the thread A, it suffices to look at the display sheet 6 on the top wall 4, and there is no need to remove the bobbin 1 from the mounting shaft and turn it over. It can be confirmed at a glance, and since the shaft insertion hole 5 of the top wall 4 is adapted to the mounting shaft, it is possible to prevent the bobbin 1 from swinging when the yarn is pulled out.

[0017]

[Effect of device]

 As described above, according to the present invention, since the display sheet that describes the necessary thread is attached to the upper surface of the top wall provided at the upper end of the bobbin body, the thread thickness, length, color number, etc. It can be checked from the outside at a glance, and it is no longer necessary to pull out the bobbin from the sewing machine mounting shaft and turn over the bobbin to check the necessary items.

Further, since the shaft insertion hole for the mounting shaft of the sewing machine is formed in the central portion of the top wall, the bobbin does not shake even when the thread is pulled out when the sewing machine is mounted on the mounting axis, and stable thread pulling can be performed. .
