2. Description of the Related Art Conventionally, in such an overedge stitch sewing machine, as shown in JP-A-1-127582, a chip storage case for storing cutting chips is provided, and the chip storage case is Since it is arranged in a limited space on the front surface of the overedge sewing machine, the shape of the opening is an elongated rectangle having a narrow width in the cloth feed direction and a wide width in the left-right direction. The accessory storage case has a rectangular cross section that is slightly smaller than the opening so that it can pass through this opening and fit into the storage space, and extends vertically when stored in the storage space. It has a box shape.
Further, the accessory storage case is configured to have a lid on the upper surface when stored in the storage space. The storage part of the accessory storage case is deeply formed toward the bottom of the lid.

[0003]

However, in the conventional accessory storage case, the storage portion of the accessory storage case is formed deeper toward the lower side of the lid, and the shape of the outlet of the accessory storage case is formed. Like the opening, it has a narrow rectangular shape with a narrow width in the fabric feed direction and a wide width in the left-right direction. When storing accessories or taking them out, the accessories are attached in a recessed position. Since the product is stored or the accessory located in the back is taken out, there is a problem that the taking-out work and the containing work are difficult.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide an overlock stitch sewing machine in which accessories can be easily stored and taken out.

[0005]

In order to achieve this object, the overlock stitch sewing machine of the present invention has a longitudinal direction and a vertical direction of the opening when the accessory storage case is stored in the storage space. It has an extending lid.

[0006]

In the overedged sewing machine of the present invention having the above-mentioned structure, the lid portion is arranged in the longitudinal direction and the vertical direction of the opening of the accessory storage case when the accessory storage case is stored in the storage space. It covers at least a part of the extending portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, the sewing machine body 1 comprises an arm portion 2 and a bed portion 3. The needle bar 4 is provided on the arm portion 2 and has a sewing needle 5 attached to the lower end thereof.
And a known looper provided in the bed portion 3 cooperate with each other to form an overedge seam on the edge of the work cloth.

The movable blade 6 is provided on the bed portion 3,
The movable blade 6 and a fixed blade (not shown) constitute a cutting device for cutting the edge of the work cloth prior to forming the overlock stitch.

The front cover 7 is rotatably attached to the front surface of the bed portion 3 at its lower edge. The guide member 8 is attached to the front cover 7 so as to be movable in the left-right direction in the vicinity of the cutting device, and is a guide surface 9 for guiding and removing the chips cut by the cutting device downward from the cutting position.
have. Further, the front surface of the front cover 7 has a through hole 13
Are formed.

As shown in FIGS. 1 and 3, a chip storage case 14 for storing chips is formed in a substantially box shape having an open upper surface, and the rear surface thereof has a through hole 13 in the front cover 7. A hooking portion 15 that is detachable and that is hooked in the left-right direction is provided in a protruding manner. The trough-shaped portion 16 that also serves as the engaging portion
Is provided on the left rear part of the chip storage case 14, and when the chip storage case 14 is attached to the front cover 7, the trough-shaped part 16 is inserted between the front parts on both sides of the guide surface 9 of the guide member 8. The chip accommodating case 14 is configured to move integrally with the guide member 8 when the guide member 8 moves due to a change in the overedging width.

When the chip storage case 14 is attached, the trough-shaped portion 16 is continuous with the guide surface 9 of the guide member 8 and the chips guided along the guide surface 9 are the troughs. It is configured to be accommodated in the chip storage case 14 through the shaped portion 16. Further, rubber support legs 17 for fixing the chip storage case 14 to the table surface or the like are provided on the lower surface of the storage container 14.

The vertical cross-sectional shape of the chip storage case 14 is a U-shape having a narrow upper mouth and a deep bottom, so that the front cover 7 has a small front space. Has been done.

The accessory storage case 18 covers the opening 14a of the chip storage case 14 which is detachably hooked in the through hole 13 of the front cover 7 and is stored in the storage space below the opening 14a. Are formed. Further, as shown in FIG. 3, the accessory space case 18 is formed in conformity with the U-shape of the storage space of the chip storage case 14 in order to maximize the storage amount thereof.

The accessory storage case 18 is composed of a main body 19 and a lid 20. When the accessory storage case 18 is attached to the chip storage case 14, the depth of the storage space of the chip storage case 14 is large. Direction, and an outlet 19c extending in the longitudinal direction of the opening 14a. The inner surface of the main body portion 19 is configured to accommodate tweezers, sewing needles, brushes and the like necessary for sewing.

The lid 20 is rotatably attached to the main body 19, and the accessory storage case 18 can be opened and closed. Further, on the inner surfaces of the main body portion 19 and the lid portion 20, engaging members 19b and 20b using known irregularities are formed so that the accessory storage case 18 can be kept closed.

Collar portions 19a and 20a are formed on the upper portions of the main body portion 19 and the lid portion 20, respectively. The collar portions 19a and 20a are used for the accessory storage case 18
When the chips are stored in the chip storage case 14, the opening 1
It is configured to be supported on the upper part of the wall surface around 4a.

As described above, since the take-out port 19c of the accessory storage case 18 is configured to extend in the depth direction of the chip storage case 14 and in the longitudinal direction (left-right direction) of the opening 14a, the storage amount can be reduced. Even if it is formed along with the depth of the chip storage case 14 to maximize the size, the accessory storage case 18 has a shallow depth, so that the accessory can be easily stored and taken out. is there. Further, since the opening area of the take-out port 19c can be made large, taking in and out of accessories becomes easier. Further, since the accessory storage case 18 is configured to fit in the chip storage case 14, the external appearance is also clean.

In this embodiment, the accessory storage case 1
8, the main body 19 and the lid 20 open and close in a double-door manner, but as shown in FIG. 4, the lid 36 on the front surface of the accessory storage case 34 is configured to be slidable with respect to the main body 38. The outlet 40 may be formed.

[0020]

As is apparent from the above description, in the overlock stitch sewing machine of the present invention, when the accessory storage case is stored in the storage space, the lid is the accessory storage case in the accessory storage case. Since it covers at least a part of the part that extends in the longitudinal direction and the vertical direction of the opening of the case, you can make the depth shallow while keeping the storage amount of the accessory storage case, and easily store the accessories, It can be easily taken out. Further, since the opening area of the take-out port can be made large, the taking-in and taking-out of the accessory becomes easier.
