Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing machine pedal for converting the depression of a foot into an electric signal and controlling each function of the sewing machine.

[0002]

2. Description of the Related Art Conventionally, two types of sewing machine pedals, one for sitting work and one for standing work, have been required.

The structure will be described below with reference to FIGS. 5 and 6.
Will be described with reference to. FIG. 5 shows a case of sitting work by a sewing machine provided with a conventional sewing machine pedal, and FIG. 6 shows a case of standing work.

As shown in FIG. 5, a pedal for a sewing machine when sitting on the sewing machine includes a pedal 1 of a sewing machine base which is depressed by a foot, and a connecting rod 10 for transmitting a displacement of the pedal 1 of the sewing machine base. A sensor 11 for converting the displacement amount of the pedal 1 of the sewing machine table transmitted through the connecting rod 10 into an electric signal, and a sewing machine control device 12 for mounting the sensor 11 and controlling the operation of the sewing machine by the signal from the sensor 11.
It consists of.

As shown in FIG. 6, when a standing work is performed by a sewing machine, a pedal 13 of a foot controller which is depressed by a foot, a sensor 15 for converting a displacement amount of the pedal 13 of the foot controller into an electric signal, and a foot controller of the foot controller. Foot controller body 14 with pedal 13 and sensor 15 attached, and foot controller sensor 1
A code 7 for transmitting a signal according to 5 and a sewing machine control device 1 for controlling the operation of the sewing machine by the transmission signal from the code 7.
It is composed of two. Here, 16 is a sewing machine main body, 1
7 is a sewing machine stand.

[0006]

In such a sewing machine pedal, when the standing work is changed to the standing work, as shown in FIG. 6, the foot controller pedal 13 and the sensor 1 are used.
5, the foot controller main body 14, and the cord 7 are separately required.

The present invention has been made to solve the above problems, and an object of the present invention is to easily perform sitting and standing work of a sewing machine.

[0008]

A sewing machine pedal of the present invention is connected to a first pedal having a hole used for fixing to a crosspiece of a sewing machine base to achieve the above object, and the first pedal. A sensor for converting the depression amount of the first pedal into an electric signal; and a sensor for connecting the first pedal to a crosspiece of the sewing machine base with a hole used for fixing, and connecting the sensor with the second pedal of the sewing machine base. A main body having a mounting hole, and further having a mounting hole for the sensor connected to the first pedal.

[0009]

According to the present invention, with the above-described structure, when a sitting operation is performed, the main body is fixed using the fixing holes to the sewing machine base, and the mounting position of the sensor for converting the pedal depression amount into an electric signal is the second pedal of the sewing machine base. By attaching the sensor to the second pedal, and attaching the sensor to the first pedal side connected to the main body at the time of standing work by connecting the sensor to the second pedal and connecting the sensor to the first pedal. It can be used for both standing work and sitting work.

【Example】

(Embodiment 1) An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, when used for sitting work,
The pedal 1 of the sewing machine stand on which the foot is stepped is connected to a sensor 2 for converting the amount of depression into an electric signal, the sensor 2 is attached to the pedal 1 side of the sewing machine stand of the pedal body 3, and the pedal body 3 is connected to the pedal body 3. It is fixed to the crosspiece 6 of the sewing machine base together with the pedal 4 by the bolt 5.

As shown in FIG. 2, when used for standing work, the pedal 4 of the pedal body 3 that is to be stepped on is connected to the pedal body 3 and also to the sensor 2, and the sensor 2 is the pedal of the pedal body 3. It is attached to the 4 side.

Reference numeral 7 is a code for transmitting an electric signal of the sensor 2 to a control device (not shown).

As described above, the pedal depression detecting device of this embodiment can be used for both standing work and sitting work without significantly changing the configuration for standing work and sitting work.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 3, when used for sitting work,
The pedal 1 of the sewing machine stand that is stepped on is connected to a connecting rod 8 that transmits the amount of depression of the pedal 1, and the connecting rod 8 is connected to a sensor 2 that converts the amount of depression into an electric signal.
Is attached to the pedal 1 side of the sewing machine base of the sewing machine main body 3, and the sewing machine main body 3 is a pedal 4 connected to the sewing machine main body 3.
At the same time, it is fixed to the crosspiece 6 of the sewing machine stand by the bolt 5.

When used for standing work as shown in FIG. 4, the pedal 4 of the sewing machine main body 3 which is stepped on is connected to the sewing machine main body 3 and to the sensor 2, and the sensor 2 is connected to the sewing machine main body 3. It is attached to the pedal 4 side of.

[0018]

As is apparent from the above embodiments, according to the present invention, one detecting device can be used for both standing work and sitting work, so that the pedal depression detecting device is easy to use.
