Description

[Detailed Description of the Invention] The present invention relates to an improvement of a presser foot storage device provided in a sewing machine frame.

With a single sewing machine that can perform multiple types of sewing, it is necessary to replace the presser foot with one specifically designed for that type of sewing each time the type of sewing changes.

There are two points to keep in mind when replacing the presser foot.

The two problems are how to easily and without error take out presser feet suitable for various sewing methods, and how to neatly store presser feet that are not in use.

It is convenient to use the hollow part of the sewing machine frame as a storage place for the presser foot, and this was already demonstrated in the 1970s-65s.
This method is known from Japanese Utility Model Publication No. 460 and Japanese Utility Model Application Publication No. 52-98238.

The device disclosed in Japanese Utility Model Publication No. 49-65460 has a plurality of compartments in which presser feet can be individually stored inside a face plate that can be opened and closed to cover the head of the sewing machine. When replacing the head, it is necessary to open the face plate, which is undesirable because the various movement mechanisms installed inside the head are exposed each time, and the space inside the face plate is relatively narrow, so it cannot be stored. The number of presser feet and the storage space allowed for each presser foot tend to be limited.

Furthermore, since the sewing method to be performed by the presser foot stored in each compartment is not displayed, there is a drawback that an inappropriate presser foot is easily taken out by mistake.

On the other hand, the device disclosed in Japanese Utility Model Application Publication No. 52-98238 has an accessory accommodating section for accommodating a presser foot, etc. and a quick reference mechanism for various sewing methods arranged in a layered manner on the upper surface of the sewing machine arm.
Each has a lid, but the top surface of the arm is not always easily visible to the worker, and many presser feet are stored in one plane apart from the sewing instructions, so there is no quick reference mechanism. There was also a drawback that a presser foot other than the one specified by the user could easily be taken out by mistake.

The present invention has been made for the purpose of eliminating the drawbacks of the prior art and providing a presser foot storage device that can satisfy both of the above two points, and its gist is as follows: a) A display board attached to the front of the pillar of the sewing machine frame and displaying the various sewing methods performed by the sewing machine vertically, and (b) Each sewing method display on the display board. Adjacent and corresponding presser feet are arranged vertically along the front corner of the right end of the pillar section, and are arranged on the front and right sides for separately storing presser feet suitable for each sewing method. It consists of a plurality of storage chambers having openings that open to the sides, and (C) a cover plate with an abbreviated cross section that covers the openings of the storage chambers in an openable and closable manner, and includes a presser foot suitable for each sewing method. The point is that the information is stored in association with the sewing method display.

Hereinafter, embodiments will be described in detail based on drawings showing examples.

In FIG. 1, 1 is a sewing machine frame, which is cut out from a bed 2, a pillar part 3, an arm part 4, a head part 5, etc.

A presser foot 6 and a needle bar 7 are disposed on the head 5 so as to be movable up and down, and a presser foot 8 and a sewing machine needle 9 are attached to the lower end of each.
is installed.

As shown in FIGS. 1 and 2, the right side of the pillar section 3 is covered by a side cover unit 10. As shown in FIGS.

side cover unit) 10 is a large number of presser foot fixed storage chambers 11
The presser foot storage chamber 11 is formed at the front corner of the right end portion of the pillar portion 3.

The lid body 13 is made of opaque aryl resin, and has an L-shaped cross section with side faces and front faces perpendicular to each other, and is inserted into the cover main body 12 so as to reach the tip of the side face. It is rotatably attached around a pair of pins 15 (only one of which is shown).

A display plate 16 is attached to the left side of the lid 13, and a presser foot storage chamber 11 is formed adjacent to the display plate 16.

The display board 16 has an elongated shape, and displays various sewing methods 1 to be performed by this sewing machine, as partially shown in FIG.
7 are listed side by side in the vertical direction.

Different alphabetic characters are printed below the sewing method display 17.

The elongated instruction board 18 placed on the left side of the display board 16 has the following information:
A sewing method display 17 and a light emitting diode 21 indicating the number of stitches are provided.

The entire front side and a part of the right side of the storage chambers 11 are opened, and a large number of storage chambers 11 are formed side by side in the vertical direction, partitioned by shelf portions 19.

This corner of the cover main body 12 has been removed in this manner, and the front side opening and right opening of the cover body 12 are covered by the front and side surfaces of the lid body 13, respectively.

Each storage chamber 11 is formed adjacent to and corresponding to each sewing method display 17, and each storage chamber 11 stores a presser foot 23 corresponding to each sewing method display 17, and a part of the presser foot 23 is stored. The same alphabetical characters as the display board 16 are engraved.

As described above, the display plate 16 is located immediately to the left of the front opening of each storage chamber 11, and is covered by the front surface of the lid 11 when it is closed.

Further, on the display board 22 attached to the front surface of the arm section 4, figures 24 (only some of which are shown) indicating a plurality of types of seam patterns are displayed, and above each figure are the same number of light emitting diodes. 26 are arranged.

There are two selection buttons 27 and 2 near the right end of the display board 22.
8 are attached.

When the left selection button 27 is pressed, the light emitting diodes 26 sequentially emit light from right to left, and when the right selection button is pressed, the light emitting diodes 26 sequentially emit light from left to right to indicate the selected stitch pattern, and by the formation of this stitch pattern. The sewing method that can be performed is light emitting diode 2.
It is designed to be instructed by the light emission of 1.

Since the present embodiment is configured as described above, there is no need to remember all the sewing methods that can be performed by forming a certain stitch pattern.

As the number of stitch patterns and sewing methods increases, it becomes troublesome or unnecessary to memorize them one by one.

To take out the presser foot, open the lid 13 and the sewing method display 17 will show the instructions from the light emitting diode 21.
A presser foot 23 to be used for performing this sewing method (for example, blind stitching) is stored in the storage chamber 11 on the right side.

Moreover, the work of taking out the presser foot 23 can be done easily and accurately.

This is because the storage chamber 11 is open not only to the front but also to the right.

In other words, if the storage chamber opens only to the front, it will be difficult to take out the presser foot unless the opening is very large, but in this example, you can insert your fingers from both the front and right side to remove the presser foot. This allows the legs 23 to be easily taken out.

Moreover, since the light emitting diode 21 and the sewing method display 17 are arranged extremely close to each other in the storage chamber 11, there is no fear of accidentally taking out a different presser foot than the one displayed.

When the sewing method changes from blind stitching to, for example, overcasting, it is necessary to replace the presser foot 23 accordingly.

The presser foot for blind stitching is stored in the storage chamber, and the presser foot for overlocking is taken out from the storage chamber.

As mentioned above, the removal operation can be performed accurately, but the storage operation can also be performed accurately.

This is because the presser foot 23 is printed with the same alphabetic characters ("A" in the case of blind stitching) as those drawn below the sewing method display 17 on the display board 16.

When the lid body 13 is closed after replacing the presser foot 23, the storage chamber 17 and the display board 16 are all covered, and the appearance is returned to its original state.

Note that the front of the right end of the pedestal section 3 is easily visible to the operator, and there is no drive mechanism installed at this corner, so there will be no problem if the presser foot storage device is installed at this corner. Therefore, dead space can be used effectively.

The present invention is not limited to the above-described embodiments, and can be modified and improved as appropriate without departing from the spirit thereof.

That is, if the lid 13 is made of translucent acrylic resin, it is convenient to be able to confirm whether or not the presser foot is stored in the storage chamber without opening the lid.

Further, it goes without saying that the display board 16 and the indicator board 18 may be integrated, and the lid 13 and the storage chamber 11 do not necessarily have to be integrated into a unit.

As detailed above, the presser foot storage device according to the present invention is
Since each of the presser foot storage chambers is adjacent to and corresponds to each sewing method display, if the presser foot stored in the storage chamber adjacent to the selected sewing method display is taken out,
This inevitably results in a presser foot that is compatible with the selected sewing method, and has the effect of virtually eliminating the risk of accidentally removing a presser foot that is not suitable for the selected sewing method.

Furthermore, since the storage chamber is formed by opening outward at the front corner of the right end of the sewing machine pedestal, the presser foot stored in the storage chamber is assembled inside the sewing machine pedestal. It has the feature that there is no risk of interference with each operating member.

In addition, the storage chamber is provided at the front corner of the right end of the sewing machine pedestal, and has openings that open in both the front and right directions, making it easy to store and take out the presser foot. Furthermore, since the storage chamber is located in a position that does not interfere with sewing, the storage chamber can be left open even while the sewing machine is running, making it easy to change the presser foot. There is no need to open and close the lid of the storage chamber each time, and the sewing machine pedestal where the storage chamber is located is close to the sewing machine bed and is firmly connected to it, so the sewing machine The vibrations generated in the storage chamber during operation are small, and there is very little risk of the presser foot falling off even if the opening of the storage chamber is left open.
