Description

[Detailed Description of the Invention] The present invention relates to a friar arm sewing machine, and more particularly to an auxiliary bed for a friar arm sewing machine.

In conventional friar arm sewing machines, the attachments are stored in a box separate from the main body of the sewing machine, and when sewing while changing attachments, the box must be brought within reach of the operator. Furthermore, when the sewing machine was not in use, it had to be moved to an appropriate location.

SUMMARY OF THE INVENTION An object of the present invention is to provide a friar arm sewing machine in which an attachment is housed in an auxiliary bed to avoid such problems.

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

1 to 3, a base 12 and a flier arm 13 protrude parallel to each other from the side surface of a main body 11 of a flier arm sewing machine 10.

Therefore, the base 12 has the main body 11 side and the free arm 1
A pin 14 is provided in a protruding manner at a position apart from 3.

The auxiliary bed 15 consists of a box 16 with an upper opening and a lid 17 for opening and closing the opening.

Thus, holes 18 are formed in both sides 18 and 19 of the lid 17, respectively.
a and 19a are formed, and pins 16a and 16b protruding from both sides of the box 16, respectively, are fitted therein.

When the lid 17 pivots around the pins 16a and 16b to close the opening, the surface of the lid 17 is flush with the surface of the flier arm 13.

Further, in the box 16, recesses 23, 24, and 25 for accommodating attachments 20, 21, and 22, and recesses 26 and 27 for accommodating other items are formed.

Furthermore, a bearing portion 28 is formed from the bottom to the top of the box 16, and the pin 14 is loosely fitted into this bearing portion 28.

Thus, the auxiliary bed 15 is pivotable about the pin 14, and the free arm 13 forms a free arm bed by itself, and together with the auxiliary bed forms a flat bed.

As described above, the present invention includes a FLIR arm and an auxiliary bed, and when the auxiliary bed is adjacent to the FLIR arm, a flat bed is formed, and when the auxiliary bed is apart from the FLIR arm, the FLIR arm is formed. In a friar arm sewing machine in which a bed is formed, the auxiliary bed is made up of a box having an opening on the upper side and a bearing part on the lower side to accommodate an attachment, and a lid for opening and closing the opening, The flear arm sewing machine is configured such that the flear arms are parallel to each other at different levels, and a pin is protruded from the base on which the auxiliary bed is placed, and the pin is loosely fitted into the bearing part. It has the effect of

■ By lifting the lid and opening the box, you can quickly replace the attachments that are neatly stored inside the box.

Therefore, compared to the case where the accessory case is housed in the auxiliary floor and the latter is pulled out in the longitudinal direction of the former, as disclosed in Japanese Utility Model Application No. 53-106154, in the present invention, the attachment can be replaced easily. There is no hassle.

■ There is no need to move the attachment storage box to another location when the sewing machine is not in use.

■ If the auxiliary bed gets in the way when you use the free arm bed to its full potential, you can easily remove the auxiliary bed from the base by lifting the auxiliary bed upwards and releasing the relationship between the bearing and the pin. can.

Therefore, compared to the case where the auxiliary bed is hinged to the arm as disclosed in Japanese Utility Model Application No. 54-125760, the present invention allows the use of a free arm bed in its complete form.

■ When the auxiliary bed is removed from the base, in the present invention, the auxiliary bed does not have a rotation pin as disclosed in Japanese Utility Model Application Publication No. 113653, , there is no chance of pins breaking.
