Abstract

PROBLEM TO BE SOLVED: To surely protect an internal mechanism from contamination and simply remove the case when it is used as a base surface extending auxiliary table by forming one of front and rear covers from a main body part for forming a lower arm when a recessed part is fitted to a lower arm and a lid member for closing the recessed part. SOLUTION: In the case of using a sewing machine case as an enlarging auxiliary table with a sewing machine main body stored therein, first a lid member 15 is removed from a from cover 12. Next, a fastener 17 is slit to the upper side to release clamping of an engagement projection 11d of a rear cover 11 side and an engagement projection 14c of a front panel 12 side. Next, the lower end of the front cover 12 is lifted up to release the engagement of a circular-arc click 11a of the rear cover 11 side 11 and a hook piece 14a of the main body part 14 side, and the rear cover 11 and the main body part 14 are disassembled to take out a sewing machine main body. When an accessory box is separated and the recessed part 16 is fitted to a lower arm and a part of a stud, the main body part 14 is served as an enlarging auxiliary table for enlarging the bed surface.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accommodates a sewing machine for sewing bags and cylinders and other ordinary work cloths, and accommodates a work bed surface when sewing a normal work cloth. The present invention relates to a sewing machine cover that can also be used as an auxiliary table to be extended.

[0002]

2. Description of the Related Art If a sewing machine cover of this type is used as a back type that accommodates the entire sewing machine, the sewing machine body must be taken out of the sewing machine cover, and a preparation work for use is troublesome. Further, in the case of a sewing machine cover in which the rear side and the front side are divided in half, the sewing machine body must be tilted and each divided case must be removed.

[0003] As a sewing machine cover having the function of a conventional auxiliary table which solves such a troublesome work, Japanese Utility Model Publication No. Sho 63-21265 discloses a lower arm having a bed surface and a leg standing upright from the lower arm. In a sewing machine having a pillar portion and an upper arm extending horizontally from the pillar portion above the lower arm, a portion between the bed surface and the upper surface of the upper arm can be covered, A sewing machine cover having an open side facing the portion is provided, and a notch engageable with the lower arm extends horizontally from one of the open front and rear sides of the sewing machine cover on one of the front and rear walls of the sewing machine cover. Formed so that when the notch is fitted into the lower arm, the outer surface of the wall where the notch is formed constitutes the same working surface as the bet surface of the lower arm. Sewing cover longitudinal dimension of the cover is set to be substantially equal to the height of the betting surface from the lower end of the machine frame is described.

When the sewing machine is not used, the sewing machine cover covers the space from the bed surface to the upper surface of the upper arm. When the sewing machine is used, the sewing machine cover is removed from the machine frame, and the sewing machine cover is removed. When the notch is rotated by 90 degrees and the notch is fitted to the lower arm, the outer surface of the wall formed with the notch of the sewing machine cover becomes an auxiliary table constituting the same work surface as the bet surface of the lower arm. It will be expanded.

[0005]

However, the above-described conventional sewing machine cover does not house all of the sewing machine body, and the lower part of the pillar and the lower arm below the base surface is exposed to the outside. When the sewing machine is covered with the sewing machine, the notch to be fitted to the lower arm when used as an auxiliary table is located on one side, and communicates the inside of the sewing machine cover with the outside. Therefore, it is conceivable that dust may enter the sewing machine cover from the notch, and contaminate the base surface and the internal mechanism. In addition, the pillars and the lower arm are in a situation where they are also damaged by dirt.

The present invention accommodates the entire sewing machine body when storing the sewing machine to reliably protect the internal mechanism from contamination, and easily removes the sewing machine from the sewing machine when it is used as a base surface expansion auxiliary table when sewing a normal work cloth. The problem to be solved is to provide a sewing machine cover that can be used.

[0007]

In order to solve the above problems, the inventors of the present invention have made various studies and have made a divided sewing machine case for storing the entire upper side except for the bottom surface of the sewing machine. It has been confirmed that the problem can be solved by closing the recess for fitting to the lower arm formed on the cover with the lid member when used as an auxiliary table to be extended.

According to a first aspect of the present invention, there is provided a lower arm on which a bed surface is formed, a pillar standing upright from the lower arm, and a pillar located above the lower arm. A box-shaped sewing machine case having a lower opening that covers an upper surface and a side surface of the sewing machine, the bottom surface of the sewing machine including an upper arm extending from the upper arm, and a rear cover that covers a rear side of the sewing machine; A front cover that engages and covers the front side of the sewing machine; and fastening means that fastens the front cover and the rear cover, wherein one of the front cover and the rear cover coincides with a bet surface of the lower arm. A main body portion having an enlarged auxiliary table surface and a concave portion fitted to the lower arm, the main body portion forming at least the lower arm of the sewing machine when the concave portion is fitted to the lower arm; It is characterized in that the is composed of a lid member for closing the recess.

(Operation) The sewing machine case having the above structure has an upper surface excluding a bottom surface of the sewing machine with a rear cover and a front cover.
The side cover is housed, and the front cover and the rear cover are fastened by fastening means. Therefore, the sewing machine case can be removed from the sewing machine only by releasing the fastening means.
The one removed cover has an enlarged auxiliary table surface that matches the bet surface of the lower arm and a concave portion that fits into the lower arm, and when the lower arm is fitted into the concave portion, at least the lower arm of the sewing machine is moved. A body part to be formed;
Since the cover is configured with a cover member that closes the concave portion of the main body, the one cover can be used as an auxiliary auxiliary table, and when storing the sewing machine, the front cover and the rear cover can be simply covered with the sewing machine. By easily closing the recess with a lid member, the sewing machine can be completely concealed and the internal mechanism can be prevented from being stained.

[0010] According to a second aspect of the present invention, the lower arm comprises:
The lower arm has a detachable accessory box and an engaging portion for locking the accessory box. When the main body is used as the expansion auxiliary table, the main body is connected to the engaging portion of the lower arm. It is characterized by having an engaged part to be locked to the.

[0011]
