Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rain lid sewing machine which is a sewing jig used when sewing a rain lid (flap) of a suit or the like.

[0002]

[Prior art]

 Conventionally, regarding rain lid sewing jigs, Jikkou 42-19830 (invention name; rain lid molding die), Jikkou 6-34328 (invention name: rain lid sewing jig), etc. have been disclosed. ing. The rain lid sewing jig is used to sew rain lids that are attached to the upper part of pockets of suits and jackets. The peripheral edge of the surface material of the rain lid is sewn with a bulge that covers the lining, and the pocket is sewn. It is a jig to sew along the curved surface of the body.

[0003]

[Problems to be solved by the device]

 The present invention is a major improvement over the conventional rain lid sewing jig. In particular, the rain lid requires a curve that bulges slightly outward when sewing to a clothing pocket. It is intended to develop a rain cover sewing machine that can create bulges in a very good shape. The bulge is formed by the projecting piece provided on the peripheral edge of the core plate in the above-mentioned Jitsuhei 6-34328 (name of the device; jig for rain lid sewing). It cannot be formed well and the bulge at the center of the rain cover is not enough. In addition, the method of partially loosening the cloth was not preferable because the cloth was inevitably misaligned or bent when the cloth had a striped pattern or a lattice. Since the rain lid is in a conspicuous part, it is very important to formally match the shape of the rain suit with the whole suit, and the present invention aims to provide a rain lid sewing machine capable of high quality and stable sewing. Next, when using a conventional rain lid sewing jig, when the front and back cloths are sandwiched between the core plates, they may slip off depending on the material, or the sewing machine may be sewn when sewing. There was also the problem of slippage during transportation. Another problem was that it was not possible to smoothly remove the rain cover from the core plate after sewing. In the above-mentioned Jitsuhei 6-34328 (name of the device; jig for sewing rain lid), the end portion of the core plate is divided, but the work of taking out the rain lid by dividing and recombining is done. There was also a problem that it took a little time and effort.

 Next, one embodiment of a rain cover sewing machine according to the present invention will be described in detail with reference to the drawings. In the rain lid sewing machine of the embodiment, since the box-shaped lid 1, the core plate 2 and the bottom plate 3 are connected at the base end portion 11, the box-shaped lid which can open and close the core plate 2 which opens and closes on the bottom plate 3 can be opened and closed. It is a structure covered with 1. The front cloth a is put on the core plate 2, the back cloth b is put under the core board, and it is sandwiched between the box-shaped lid 1 and the bottom plate 3. The rain cover is sewn by sewing along a contour with a sewing machine.

Describing with reference to the drawings, the core plate 2 in the shape of the substantially rain cover A has a plurality of four rod-shaped convex portions 6 extending in the short side direction in the center of the surface and arranged in parallel at intervals. A bending line 5 having a bending groove 50 formed on the lower surface is formed at one end to form a bending end 20, and a bending end 12 is connected to the base end 11 at a bending line 12 as shown by arrow 24. It is a substantially rectangular plate made of synthetic resin. Further, a cloth slip prevention tape 13 is attached to the peripheral edge of the surface so that the front cloth a does not slip. The refraction end 20 is refracted as shown by an arrow 21 in FIG. 1, and the base of the refraction end 20 is separated from the base end 11. Reference numeral 10 in the figure denotes a notch in which the bending end portion 20 of the core plate 2 is separated from the base end portion 11. The bending end 20 is used to pull out the rain lid A from the core plate 2 by bending it as shown by an arrow 21 when the rain lid is pulled out from the core plate 2 to shorten the lateral length of the core plate 2. Four convex portions 6 are provided in the center of the surface, and the cross section thereof is formed into a trapezoid so as not to damage the cloth. The convex portion 6 can be changed in shape such as having a semicircular cross section or a wavy shape, and the design of the number of attached pieces can be changed. The convex portion 6 formed on the surface is such that the surface material a is crawled along the convex portion 6 and the surface material a of the rain lid is bulged in all directions. Therefore, the shape is not limited to the above example as long as the shape meets this requirement.

A box-shaped lid 1 and a bottom plate 3 which are flexibly connected at a base end 11 with the core plate 2 in the middle are connected to each other. The box-shaped lid 1 is flexibly connected to the base end portion 11 at a fold line 4 as shown by an arrow 23, and is connected to the core plate 2 in parallel at one long edge and at a small distance to the outer periphery of the core plate 2. In addition, there is provided a hanging frame 1a to be fitted and a long hole 7 into which the convex portion 6 of the core plate 2 is fitted or a concave portion (not shown) is provided on the plate surface 1b, and the contour of the core plate 2 is further provided on the peripheral surface. A guide ridge 8 having a shape similar to that of a line (similar to a suture line of a rain lid) is formed, and the outer side thereof is formed into a rough surface orbit 9 having a fine uneven surface. The long hole 7 is sized to fit the convex portion 6 of the core plate 2 with a gap, and its cut end is rounded so as not to damage the land. The long holes 7 sandwich the surface material a in a wave shape with the convex portions 6 of the core plate 2 to create and guarantee a bulge of the material. In the embodiment, the long hole 7 is a through hole, but it may have a concave shape or a concave wave shape. The guide ridges 8 and the rough surface tracks 9 on the outer side of the guide ridges 8 guide the drive wheels 31 equipped with the sewing needles 30 so as not to slip. The sewing needle 30 advances the front cloth a and the back cloth b protruding from the rain cover sewing machine along the contour of the rain cover sewing machine. When the drive wheel 31 is not used at the time of sewing, the operator can easily operate and operate by touching the guide ridge 8 with the operator's fingertip, and the guide ridge 8 also serves as a slip stopper for the operator's fingertip. It can protect the fingertip from sliding toward the needle. The equipment of the guide ridge 8 is very practical in practice.

The bottom plate 3 is a contoured plate body that closes the box-shaped lid 1 into which the core plate 2 is fitted, and a cloth slip prevention tape 13 that prevents the back cloth b from slipping is attached to the peripheral edge of the surface. The bottom plate 3 has its front surface flattened to the joint portion with the core plate 2, and its back surface flattened to the base end portion 11 so that it is always horizontal with the sewing machine.

The use of the rain lid sewing machine of the present invention is extremely simple and does not require special learning or skill. As described above, the present invention has a structure in which the openable and closable core plate 2 on the bottom plate 3 is covered with the openable and closable box-shaped lid 1, the front fabric a is put on the core plate 2, and the back fabric b is placed below. The desired rain cover A can be sewn by putting it between the box-shaped lid 1 and the bottom plate 3 and squeezing out the two protruding fabrics a and b along the contour of the guide ridge 8 with the drive wheel 31 and sewing them with a sewing machine. . By the cloth misalignment prevention tapes 13 and 13 attached to the core plate 2 and the bottom plate 3, the materials a and b are fixed even during sewing by driving the sewing machine and are not sewn with misalignment.

When the front cloth a is put on the core plate 2 and the back cloth b is put under the core plate 2 and sandwiched between the box-shaped lid 1 and the bottom plate 3, the front cloth a is placed on the convex portion 6 of the core plate 2 and this. It is sandwiched between the long holes 7 of the box-shaped lid 1 which is covered with a space, and has an extra bent portion which is wavy in a front view and trapezoidal in a side view. The extra bending part allows the fabric to be bent from the left and right front and back to the center, forming an overall bulge, and the fabric pattern is not displaced or distorted.

The bending end 20 of the core plate 2 is bent as shown by an arrow 21 when the rain cover is pulled out from the core plate 2, and the lateral length of the core plate 2 is shortened to pull out the rain cover A from the core plate 2. To use for. In FIG. 2, the front cloth a and the back cloth b are sewn in a bag shape from the arrow Y to the arrow Z. If the non-sewn portion on the fold line 4 side is shorter than the bottom sewn portion, the bag is sewn. Unable to pull out the sewing cloth. Therefore, by folding the bending end portion 20 of the core plate 2 inward, the entire length can be shortened and the bag-shaped cloth can be easily pulled out. The bent end portion 20 of the core plate 2 is useful not only in the case of such a special shape, but also in the case where the sewing becomes difficult and the pulling out work which does not burden the cloth.

When the stitching is finished, the rain lid A stitched from the core plate 2 is pulled out by using the bending end 20. Turn it over, insert an elastic thin plate (metal plate), and iron it to complete a rain cover with a bulge on the surface.

The rain lid sewing machine of the present invention is used for a rain lid of a suit or a jacket, but can be applied to various products as long as it has the same shape and structure as the rain lid A. When applying to other shapes of clothing flaps such as flaps (lids) of inner pockets of outerwear, patch pockets, trousers bottom pockets, etc., change the overall shape of the core plate 2 to a shape corresponding to the flaps. The box-shaped lid 1 and the bottom plate 3 provided with the guide ridges 8 adapted to this may be prepared. By changing the design of the core plate 2 etc., it can also be used for sewing bag-shaped shoulder boards and appliqués with bulges.

[Effect of device]

 The rain lid sewing machine according to the present invention is configured and used as described above, and has the following unique technical effects. When sewing two cloths into a certain shape, it is extremely difficult to lay two cloths flat and allow only one cloth to be loose. In the conventional sewing, there is no looseness in the surface material and both ends of the rain cover are warped to the front side, which is not desirable in appearance and the product value is low.However, if the rain cover sewing machine of the present invention is used, When the front fabric has sufficient swelling (looseness), the rain cover will warp to the lining side, and the inside of the seam will have a rounded shape that will fit the body line. In the rain lid sewing machine of the present invention, long bar-shaped convex portions are provided in a row in a relatively wide area in the center of the surface of the core plate. Since the convex portion is not partial, a sufficient bulge can be formed. The convex portion allows the front fabric to be placed from the left and right front to the center, forming an overall bulge, and the fabric pattern is not displaced or distorted. The rain lid sewing machine has a structure in which the openable and closable core plate on the bottom plate is covered with an openable and closable box-shaped lid. Although it is sandwiched and fixed by, the cloth misalignment prevention tape is attached, so cloth misalignment does not occur during sewing, so accurate sewing can be performed. The desired rain lid can be sewn by sewing the squeezed out material along the contour of the box-shaped lid with a sewing machine.However, by providing the guide ridges and the rough track of the drive wheels on the surface of the box-shaped lid, the operator The efficiency of the sewing work is improved by protecting the fingertips of the machine and applying the drive wheel. Since the core plate has a bent end, the rain lid can be easily pulled out from the core plate by bending the sewn rain lid when pulling it out to shorten the length. As described above, the present invention is a jig that can improve the manufacturing safety and efficiency in sewing rain lids and can provide high-quality rain lids, and has practical value and commercial value. It is extremely expensive.
