Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-moving jig for a bead capable of pattern sewing a ball in a pocket.

[0002]

2. Description of the Related Art A pocket's bead is sewn in two places in parallel with each other to a base fabric by looking at a folded bead fabric.
A cut is made in parallel between the two seams from the back side of these cloths, and the ball-shaped cloth is pushed back so as to be folded at this cut. Conventionally, in the sewing of the bead of such a pocket, it is general that a sewing person draws a line on a cloth and irons the cloth to stabilize the base cloth and the bead cloth, and to perform parallel stitches matching the width of the pocket. The needle-moving jig developed for pattern sewing of this kind of bead has not existed in the past.

[0003]

[Problems to be Solved by the Invention] The sewing of the bead of the pocket is an index for improving the skill of the sewn person, and it takes a lot of time and labor such as ironing, and in order to sew a ball of a desired straight size. , Requires considerable skill. Therefore, it would be extremely useful if the pocket balls could be sewn by so-called pattern sewing.
However, it is meaningless that a dedicated sewing machine is needed for that purpose or that the work takes time.

It is an object of the present invention to provide a hand-moving jig for a bead that can easily sew a ball in a pocket without requiring skill.

[0005]

SUMMARY OF THE INVENTION To achieve the above object, the present invention is to hold a sewn base cloth and a edging cloth applied to a pocket mouth portion of the sapling cloth in a sewn state. This is a hand-moving jig for bead sewing, in which the guide protrusion provided on the periphery of the needle hole of the sewing machine guides the needle and sew the bead on the base cloth to sew the bead of the pocket. hand,
The upper surface includes a base plate formed with a concave groove for accommodating the sewing portion of the bottom cloth and the beaded cloth, and a pressing plate that faces the upper portion of the base plate and presses and holds the sewing portion in the sewing state. It is characterized in that it has a pair of guide slits which are formed in parallel to each other on the groove bottoms of the concave groove, are slidably engaged with the guide protrusions, and have the sewing machine needle faced from above.

[0006]

In the recess of the base plate, the sewn portion of the base cloth and the beaded cloth is accommodated, and the pressing plate is made to face the base plate so as to press and hold this portion in the sewn state. In this state, the base plate is set so that one of the guide slits engages with the guide protrusion provided on the peripheral edge of the needle hole of the sewing machine, and the base plate is moved so as to be in sliding contact with the guide protrusion to perform the hand movement. next,
The base plate is set again so that the guide slit of the other side engages with the guide protrusion of the sewing machine, and similarly, the guide slit is guided by this guide protrusion to perform the hand movement. In this case, since the sewn portion of the bottom cloth and the beaded cloth is stably held by the pressing plate and the recessed groove, and both guide slits are formed in parallel with each other, by the needle movement guided by the guide slit. You can make two parallel seams.

In order to prevent the displacement of the beaded cloth in the groove, the beaded cloth is wrapped in the beaded cloth and is accommodated in the groove together with the sewing portion of the base cloth and the beaded cloth. It is preferable that the shaping plate is further provided, and in order to fix the shaping plate, it is formed in a fork shape in which a portion facing the guide slit is cut out.

Further, in order to easily confirm the sewing length according to the mouth width of the pocket without drawing, it is desirable to form a scale along the guide slit on the upper surface of the pressing plate.

Is divided into four equal parts in the width direction, and the center line portion is aligned with the position of the pocket mouth, and is sewn in parallel at two points along the equal line parts on both sides of the center line.

Next, as shown in FIG.
With the beaded cloth 21 sewn on the inside, turn it over, and make a cut 24 at the position of the pocket opening, that is, the position of the center line of the two seams. The cut 24 is deep enough to reach the bead 21 and has a length substantially equal to the mouth width of the pocket, and both sides are cut into a "Y" shape. When the cut 24 is made, as shown in FIG. 7, the edging 21 is folded from the cut 24 to the back side of the edible cloth 22 so that the front side of the edible cloth 22 has a desired pocket width. , The so-called twin ball edge is completed. Although not shown, a bag cloth is sewn to the extended end of the beaded cloth 21, and after the ball cloth is completed, the bag portion of the pocket is sewn by the bag cloth and flaps are attached.

Next, the hand movement jig for the bead will be described. FIG. 1 is an exploded perspective view of a hand movement jig, and FIG. 2 is a perspective view of a sewing machine in a state where a bead is pattern-sewn using the hand movement jig.

As shown in both figures, in this hand movement jig 1, a pressing plate 5 composed of a first plate 6 and a second plate 7 is horizontally placed on a base plate 2 composed of an upper base 3 and a lower base 4. It is configured so as to be rotatable in any direction. An opening 3a is formed in the upper base 3, and a groove 8 is formed in the central portion of the base plate 2 by adhering the upper base 3 to the lower base 4.
The bottom cloth 22 is placed on the base plate 2 so that the pocket mouth is aligned with the center line of the groove 8.
Is fitted into the groove 8 such that the shaping plate 9 is sandwiched between the folded and folded cloths. That is, as shown in FIG. 3, the beaded cloth 21 is wound around the shaping plate 9, and the beaded cloth 21 is fitted into the recessed groove 8 from above the iris cloth 22 on the base plate 2 and set. To do. As a result, the sewn portion 25 of the full bloom 22 and the beaded cloth 21
Will be accommodated in the groove 8.

The base plate 2 is made of transparent plastic or the like for both the upper base 3 and the lower base 4, and has a structure in which the upper base 3 is bonded onto the lower base 4.
However, in this case, the upper base 3 and the lower base 4 may be integrally formed. Groove 8 of base plate 2
Two guide slits 10, 10 extending in the longitudinal direction are formed in parallel with each other in a portion corresponding to the groove bottom of the sewing machine 41. An annular guide provided on the periphery of the needle hole 42 of the sewing machine 41 at each guide slit 10 is formed. The needle 43 is slidably engaged with the protrusion 43 to guide the hand movement (see FIG. 4). Each guide slit 10 is formed so that the needle hole 42 of the sewing machine 41, that is, the sewing machine needle 44 faces the center line from above, and the longitudinal direction thereof is formed to be somewhat longer than the length of the pocket opening to be manufactured. The positions of the center lines of both guide slits 10, 10 correspond to the bisectors on both sides of the center line when the width of the concave groove 8 is set to the width of the folded bead cloth 21, which is divided into four equal parts. . That is, the size of the bead is adjusted by the width of the groove 8 and the center lines of the guide slits 10, 10.

The shaping plate 9 is formed in a fork shape with a brass plate, a copper plate or the like, and is composed of a base portion 9a and three fork pieces 9b, 9b, 9b extending from the base portion 9a. The two slits 11, 11 composed of these three fork pieces 9b, 9b, 9b are formed so as to match the guide slits 10, 10 of the base plate 2, and the fork piece 9b and the sewing machine needle 44 are formed. It doesn't conflict. That is, in the beaded cloth 21, the seam 23 is formed in the slit 11 portion between the fork pieces 9b in a state in which the shaping plate 9 is wrapped, and the seam 23 forms two beaded portions on both sides thereof. The shaping plate 9 is adapted to be fitted into the opening 3a of the upper base 3 forming the concave groove 8 in a state of being wrapped in the bead cloth 21, and the tip portion of the fork piece 9b has the opening 3a. Three notches 3b, 3 formed at one end in the longitudinal direction
It is stably held by engaging with b and 3b. This allows
The slits 11 between the fork pieces 9b are kept parallel to each other, and a pair of beads having a uniform width and exactly the same shape are sewn in the longitudinal direction.

The pressing plate 5 is for holding the sewn portion 25 of the base cloth 22 and the edging cloth 21 set in the concave groove 8 of the base plate 2 during the movement of the hand, and is the first plastic plate. 6 and the second plate 7. The first plate 6 and the second plate 7 are rotatably attached to the base plate 2 by screws 12 and 12 provided at the tips thereof, and are opened and closed in opposite directions in a horizontal posture. That is, the first plate 6 and the second plate 7 are rotated to the open position to set the spectacle base cloth 22 and the edging cloth 21, and then they are rotated to the closed position to rotate these porcelain base cloths. The cloth 22 and the beaded cloth 21 are pressed down.

The first plate 6 and the second plate 7 in the closed position have a desired gap 13 between them and the base plate 2
The width and the position of the gap 13 in the left-right direction are fitted to the guide slit 10 of the base plate 2. As a result, the sewing machine needle 44 and the first plate 6 and the second plate 7 do not come into contact with each other. At the same time, the presser 45 of the sewing machine 41
However, it comes into contact with the plates 6 and 7 in the closed position so as to straddle the plates 6 and 7 and lightly presses the entire hand movement jig 1 during the movement of the hand (see FIG. 2). The presser 45 is more preferably composed of a pair of rollers rolling on the pressing plate 5.

A scale 14 is engraved on the half surface of the first plate 6 on the side of the second plate 7 along the gap 13, and the scale 14 has a length corresponding to various pockets. The seam 23 is easily sewn. On the other hand, the second plate 7 is formed with an elongated hole 15 extending in the longitudinal direction near the first plate 6. The elongated hole 15 is formed in the guide slit 10 of the base plate 2 and has substantially the same shape as that of the guide slit 10. When the needle is moved in this portion, the sewing needle 44 is formed.
Is coming. In addition, the first and second plates 6 and 7 are attached to the base plate 2 via a hinge at their tips.
Alternatively, the first and second plates 6 and 7 may face the base plate 2 so that they can be tilted up and down.

Referring now to FIGS. 2 and 4,
The procedure of the pattern sewing of the bead by the hand movement jig of this embodiment will be briefly described. First, both the first and second plates 6 and 7 are rotated to the open position, and the base cloth 22 and the beaded cloth 21 with the shaping plate 9 wound therein are set on the base plate 2. Next, the first and second plates 6,
7 is rotated to the closed position so that the base cloth 22 and the beaded cloth 21 are pressed into the concave groove 8 of the base plate 2 and are held so as not to move. In this state, the hand movement jig 1 is set so that one guide slit 10 engages with the guide protrusion 43 of the needle plate 46, and the hand movement jig 1 is moved forward with the guide slit 10 slidingly contacting the guide protrusion 43. Move to and move the hands. If you make one seam 23 in this way,
The other guide slit 10 of the needle handling jig 1 is engaged with the guide protrusion 43 of the needle plate 46, and the needle is moved in the same manner to form two stitches. .

As described above, according to the needle handling jig 1 of the present embodiment, the sewing portion 25 of the base cloth 22 and the beaded cloth 21 is fixedly held in the sewing state, and the sewing machine 41 is held by the guide slit 10. Since it is possible to guide the needle movement, it is possible to sew a pattern on the bead, which enables high-quality and stable sewing regardless of skill. Moreover, wire drawing and ironing are unnecessary, and the preparation time prior to sewing is shortened, so that the workability as a whole can be improved.

In this embodiment, the needle handling jig for sewing the edge of a normal twin ball has been described. However, the size of the ball can be sewn as well as the size of the ball by sewing the single ball by changing the dimensions of each part arbitrarily. It is also possible to form a guide slit or the like in a curved shape and to sew a curved bead. Further, although the main part of the hand movement jig is made of plastic, the present invention is not limited to this, and may be made of another material, for example, a metal plate such as aluminum.
