Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ruler for a sewing machine that is used as an attachment by being installed in the bed of a sewing machine as required.

[Problems that conventional techniques and ideas attempt to solve]

Hitherto, rulers for sewing machines of this type have been known in various configurations, but all of these have complicated configurations, are difficult to use, and are difficult to use.
They had one or more of the following deficiencies, such as the need to create new mounting holes in the base for mounting to the base, and the difficulty in adjusting dimensions.

[Means for solving problems]

The present invention consists of a vertically oriented mounting leg 2 having mounting holes 1 and 1' with a horizontally oriented surface plate 3 extending from the upper side, and an inverted U-shaped groove 13 on the lower surface that is horizontally rotatably supported on the surface plate 3. a swinging member 16 having a structure, a rod-shaped ruler body 19 slidably inserted into the inverted U-shaped groove 13, a tightening bolt 22 that fixes the ruler body 19 in the sliding position, and a surface plate 3. There is an insertion hole 7 formed by fixing the round block 4 to the side surface of the tip of the swinging member 16, which is pushed into the insertion hole 7 when the swinging member 16 is oriented left and right. The purpose of the present invention is to provide a new sewing machine ruler which eliminates all of the above-mentioned defects by providing a protruding insertion piece 24.

〔Example〕

In the embodiment shown in the figure, a horizontally oriented surface plate 3 is installed on the upper side of a vertically oriented metal mounting leg 2 that is provided with a pair of vertically long mounting holes 1 and 1'. By fixing the square block 4 facing forward with screws 5 on the front half of the section, an insertion hole 7 is formed on the lower side of the horizontal section 6 of the square block 4. Standing part 8 on the edge of the spot
, cut a screw hole 10 in this raised part 8, and advance the adjuster screw 11 into the screw hole 10.
It is screwed so that it can be freely retracted, so that the inner end of the adjuster screw 11 enters deeper into the insertion hole 7 when moving forward and shallower when moving backward, and furthermore, an inverted U-shaped groove 13 is formed on the bottom surface on the surface plate 3. Swinging members 16 each having a projecting portion 15 are disposed on the side surfaces of the end portions, and the projecting portions 15 of the swinging members 16 are supported by a support shaft 17 at the latter half of the tip edge of the surface plate 3. In addition, a long slide hole 18 parallel to the groove 13 is formed in the top wall of the inverted U-shaped groove 13, and guide curves 19 are provided at both ends in the inverted U-shaped groove 13. ′、
A rod-shaped ruler body 19 with a diameter of 19" is inserted so as to be slidable and reversible, and screw holes 20, 2 for effective length selection are provided on the longitudinal line of this ruler body 19.
0', 20'' and the corresponding screw holes 20, 20', 2
Tightening bolt 2 with one knob 21 of 0″
2 through the slide hole 18, the ruler main body 19 is fixed to the swinging member 16 so that its effective length can be changed, and a tongue-shaped insertion piece is attached to the side of the tip of the swinging member 16. 24 is provided protrudingly, and this insertion piece 24 is pushed into the above-mentioned insertion hole 7 when the swinging member 16 is oriented left and right, and the frictional force between the walls of the insertion piece 24 and the insertion hole 7 The horizontal orientation of the swinging member 16 is maintained by this, and the tip of the swinging member 16 abuts against the inner end of the adjuster screw 11. In addition, 25 in the figure is a washer,
26 is the sewing machine body, 27 is the horizontal tube bed, 29,2
Reference numeral 9' indicates a thick part of the mounting screw 30 for thick objects.

[Effect]

Since the present invention has the above-mentioned structure, first, the surface plate 3 is placed on the horizontal cylinder bed 27, and the mounting legs 2 are brought into contact with the side surfaces of the horizontal cylinder bed 27, respectively, and the whole is mounted on the horizontal cylinder bed 27. The whole is mounted on the horizontal tube bed 27 by mounting the frame and fixing the mounting legs 2 to existing holes (not shown) with mounting screws 29, 29', and in this mounted state, the ruler main body 19 is installed. When you do not need the ruler body 19, put your finger on it and turn it to the position shown by the imaginary line in Figures 1 and 2, and when you need it, insert it back to the position shown by the solid line in the same figure. The insertion piece 24 is inserted into the insertion hole 7, and the ruler body 19 is
If you want to change the effective length of the bolt, loosen the tightening bolt 22 and move it within the slide hole 18, or move the tightening bolt 22 to another selection screw hole 20, 20 as necessary. ', 20'', and when you want to finely adjust the horizontal angle of the ruler body 19, move the adjuster star screw 11 forward and backward. Furthermore, when sewing thick items, adjust the ruler body 1.
9 so that the thick part 30 faces forward for thick objects, and backwards for thin objects, and further adjusts the height and angle of the surface plate 3 relative to the bed 27. If so, use the mounting screw 29,
29' is loosened once, the mounting leg 2 is moved along the mounting holes 1, 1', and then the mounting screws 29, 29' are tightened.

[Effect of idea]

As mentioned above, this invention has a horizontal surface plate 3 on the upper side.
a vertically oriented mounting leg 2 having mounting holes 1 and 1' extending therefrom; a swinging member 16 having an inverted U-shaped groove 13 on its lower surface supported horizontally rotatably on a surface plate 3;
It is formed by a rod-shaped ruler body 19 slidably inserted into the groove 13, a tightening bolt 22 that fixes the ruler body 19 in the sliding position, and a square block 4 fixed to the surface plate 3. and an insertion piece 24 protrudingly provided on the side surface of the tip of the swinging member 16 so as to be pushed into the insertion hole 7 when the swinging member 16 is turned left and right. This solves all of the following deficiencies: the configuration is complicated, it is difficult to use, it is necessary to create a new mounting hole in the same base to install it to the base, and it is difficult to adjust the dimensions. In addition, the insertion hole 7 formed by fixing the square block 4 to the surface plate 3 has an excellent effect of completely achieving the purpose of the present invention.
and an insertion piece 24 protruding from the side surface of the tip of the swinging member 16 so that it can be pushed into the insertion hole 7 when the swinging member 16 is oriented left and right. When the movable member 16 is placed in the usage state facing left and right, the usage state is maintained by pushing the insertion piece 24 into the insertion hole 7, and it has practical effects such as being extremely convenient for use. It is something that you have.
