[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sewing jig used for sewing a rain cover (flap) of a suit or the like and a rain cover of an inner pocket.

[0002]

[Prior art]

 Conventionally, rain lid sewing jigs are disclosed in Japanese Utility Model Publication No. Sho 42-19830 (invention name: rain lid molding die), Jitsuhei 6-34328 (invention name: rain lid sewing jig), No. 63-27085 (the title of the invention; an automatic sewing device), Japanese Patent Publication No. 7-16552 (the title of the invention: a jig for sewing left and right rain lids) and the like are disclosed.

[0003] The rain lid sewing jig is used when sewing a rain lid that is attached to the upper part of the outer jacket pocket of a suit or jacket, and the peripheral edge of the surface material of the rain lid covers the lining. It is a pattern making jig for sewing with a slight looseness and for bending to follow the curved surface of the body. The rain cover sewing jig is made individually according to the shape and design of the suit and rain cover.

[0004]

[Problems to be solved by the invention]

 The present invention is an improvement of the conventional rain lid sewing jig. It creates a curve and looseness peculiar to a rain lid in an extremely good shape, is easy to use during sewing, and is easy to pull out after sewing. Is an issue.

In the above Japanese Utility Model Publication No. 6-34328 (name of device; jig for rain cover sewing), the looseness is formed by an overhanging piece provided on the peripheral edge of the core plate. Then, the slack cannot be formed sufficiently, and the slack in the central part of the rain cover is not enough. In the conventional loosening formation, only the thickness of the core plate was used to form a single mountain-shaped surplus portion.

When the outer material has a striped pattern or a lattice pattern, the pattern inevitably shifts or bends, and a skilled sewing technique is required. When using a conventional rain lid sewing jig, depending on the material of the material when inserting the front and back linings, it may slip and slip, or slippage may occur when carrying the sewing machine when sewing. There was also a problem. In the above Japanese Patent Publication No. 7-16552 (Invention title: jig for sewing left and right rain lids), since the movable part is operated when setting the outer material, the lining may move and may not be fixed accurately, which may cause a deviation.

Originally, the looseness (looseness, surplus portion) of the outer material of the rain cover must be put on the front side of the outer material at the time of sewing, whereas the conventional rain cover sewing jig pulls much on the back side of the outer material. It was how to insert the looseness on the back side, which was contrary to the original request.

[Embodiment of the invention]

 Next, an embodiment of a sewing jig according to the present invention will be described in detail with reference to the drawings. In the embodiments of FIGS. 1 and 9, a frame body (1) having a substantially horizontally long rectangular shape and having a hollow window (10), and a hollow base (10) of the frame body (1) with a gap between the base ( 14) is provided with a core plate (2) which is flexibly connected and swings up and down to move in and out, and in a gap between the frame body (1) and a core plate (2) flexibly connected with a base portion. Further, an inner frame (3) having a shape similar to that of the frame body (1) is provided with its base end fixed, and is provided between the frame body (1) and the inner frame (3) and between the inner frame (3). A small gap (12) (13) is formed between the core plate (2) and the backing plate (4) which is connected to the frame body (1) at the base side (15) in a freely bendable manner and the lining. It is a structure provided with a push plate (5). FIG. 1 is a perspective view, and FIG. 9 is a plan view showing a state in which the outer material pressing plate (4) and the lining material pressing plate (5) are opened.

With reference to the frame body (1), the movable core plate (2) is provided in the hollow window (10) of the fixed frame body (1) and the fixed inner frame (3). become.

As shown in FIG. 5, the set of the outer material A and the lining material B in the embodiment of FIGS. 1 and 9 presses the lining material B with the outer material pressing plate (4) and the lining material pressing plate (5), while the outer material A is The outer peripheral portion is pressed against the outer material pressing plate (4) by the frame body (1), rolled up on the inner frame (3), and the center portion of the outer material A is pressed by the core plate (2) while maintaining the convex portion with scissors. , Press the other outer material push plate (4) to set outer material A and inner material B. In other words, the outer material A is inserted into the small gap (12) between the frame body (1) and the inner frame (3) to be spread, and is held by the core plate (2). With this pressing method, the outer material A has a slack and does not shift during sewing. The outer material A is sewn to a flat lining material B with a wavy surplus portion at the periphery and a convex surplus portion at the center.

The lining B is sandwiched between the outer material pressing plate (4) and the inner material pressing plate (5), and the outer material pressing plate (4) and the inner material pressing plate (5) are firmly aligned with each other. It will not slip out. Both the fabrics A and B are sewn with a sewing machine along the contour of the lining press plate (5) which is the contour shape of the sewing jig body to sew a rain cover.

The outer surface of the backing plate (5) located on the outermost side is provided with a non-slip means so that the feed dog of the sewing machine does not slip, and the core material is provided so that the outer material A does not slip. Anti-slip tape, etc. is attached to the surface of the plate (2). Making the surface of the lining push plate (5) a rough surface (uneven surface, etc.) that does not slip serves as a guide for the teeth of the sewing machine and improves sewing efficiency and accuracy.

The core plate (2) is a substantially rectangular thick plate made of synthetic resin.

In the embodiment shown in FIG. 1, the frame body (1) is provided with a front surface pressing plate (4) and a lining pressing plate (5) flexibly connected to the frame body (1) at a base portion (14). It is installed on both sides of the structure so that it can be used as both the right and left rain cover sewing jigs.

FIG. 2 shows an example of a means for preventing the backing plate (5) from slipping, which is obtained by applying rubber to the surface of the backing plate (5) to prevent slippage. There is. FIG. 3 shows a backing plate (5) having an uneven portion (51) formed on the outer peripheral edge. The uneven portion (51) on the surface of the liner pressing plate (5) forms a rough surface orbit, meshes with the feed dog (62) of the sewing machine to prevent slipping, and guides and advances the sewing jig body at a constant speed. Since the sewing needle (60) proceeds to sew the outer fabric A and the lining B protruding from the sewing jig along the outline of the sewing jig, sewing mistakes are less likely to occur.

FIG. 4 is a plan view showing a liner pressing plate (5) used when sewing a curved rain cover (inner pocket of a suit, hip pocket of pants, etc.). It is shown that the present invention can be applied to rain lids with various curved contours and various shapes. In such a case, the frame body (1), the dressing plate (4) and the lining stamping are shown. The shape of the plate (5) is appropriately designed, and the pressing metal fitting (6) as shown in FIGS. 6 to 7 is used to sew as shown in FIG.

The holding metal fitting (6) shown in FIG. 6 is characterized in that the lower side surface portion (61) which comes into contact with the sewing jig is curved in an arc shape. The bow-shaped curved lower side surface portion (61) is in good contact with the curved contour of the sewing jig as shown in FIG. 4 so that the needle can be smoothly moved as shown in the side view of FIG. 9 during sewing. A new configuration is also possible in which the lower side surface portion (61) of the holding metal fitting (6) is curved in an arc shape. Since the presser fitting (6) is located on the sewing jig and the sewing position is difficult to see, the side of the guide hole of the sewing needle (60) of the presser fitting (6) has a sewing position as shown in FIG. Is attached (63).

FIG. 5 is a lateral side view showing sewing by setting the material of the rain lid using the sewing jig configured as shown in FIGS. 1 and 9, and showing the sewing on the front and back of the frame body (1). It has a push plate (4) and a lining push plate (5), and by using this sewing jig inside out, the left and right rain lids can be sewn. FIG. 5 is a lateral side view showing a state immediately before the front material A and the lining material B are set and the stitches (6) are sewn together.

The outer material A is set by forming a wavy shape on the peripheral edge so as to wind the inner frame (3). In FIG. 5, the front side of the outer material A is the surface that contacts the outer material pressing plate (4) and the surface that faces the lining material B. It is possible to change the size of the surplus portion of the outer material A by changing the winding method of the inner frame (3) or changing the width of the inner frame (3). The lining B is sandwiched between the front material pressing plate (4) and the lining material pressing plate (5) and is aligned with the front material A. Then, the rain lid is created by fitting together along the contour of the sewing jig.

In the configuration of FIG. 1, since the core plate (2) is vertically symmetrical and the sewing jig body is turned over, the left and right rain lids can be sewn. Explaining just in case, if only one of the left and right rain lids is made, in the sewing jig shown in FIG. 1, one of the surface pressing plate (4) and the lining pressing plate (5) is used. Should not be provided.

The use of the sewing jig of the present invention is extremely simple and does not require special skill. As described above, the substantially rectangular (slightly larger cloth than the rain cover) outer material A is put in the small gap (12) between the frame body (1) and the inner frame (3) to protrude the peripheral edge, and the core plate (2 ) Is lowered to form a convex surplus portion on the outer material A, and the lower outer material pressing plate (4) is closed to fix the outer material A. When the upper dressing plate (4) and the lining dressing plate (5) on the upper side are closed, the dressing material A is pressed from above and below by the dressing plate (4).

In addition, a lining B having a substantially rectangular shape (a cloth slightly larger than the rain cover) is inserted between the outer surface pressing plate (4) and the lining pressing plate (5), and the peripheral edge is protruded from the jig body. Let With this, the front material A and the lining material B can be set. A desired rain cover A can be sewn by sandwiching the upper and lower surface push plates (4) and the lining push plate (5) and sewing both the protruding fabrics A and B along the contour with a sewing machine. The outer material A and the lining material B are fixed even during sewing by the driving of the sewing machine, and they are not sewn with deviation.

On the core plate (2), ear pieces (21) protruding at an angle of about 45 degrees are provided at the front left and right corners. For this reason, the corners of the outer material A can be sufficiently loosened to maintain a surplus portion. When the lining B is placed below and sandwiched between the outer fabric pressing plate (4) and the lining fabric pressing plate (5), the outer fabric A passes through the space between the inner frame (3) and the core plate (2) and has a wavy extra bent portion. It is possible to form a uniform surplus portion over the entire periphery because it is even and reliable. Excessive bent portions on the inner frame (3) cause the cloth to be bent from the left and right front and back to the center to form overall slack, and the cloth pattern is not displaced or distorted. For this reason, the rounded portion is sewn into a shape conforming to the back side and does not bounce outward.

When the stitching is completed, the bag-like stitched rain lid is removed from the inner frame (3). At this time, since it is not pulled out from the core plate (2) as in the past, it is pulled out from the inner frame (3), so that the material and shape of the inner frame (3) can be pulled out smoothly even when pulling out. . Turn over the sewn rain cover, insert the elastic thin plate (metal plate) into the rain cover bag, and apply iron. The looseness that the outer material A has when it is sewn, and the outer material A is covered and curved so as to cover the lining material B, and the rain lid is completed.

The sewing jig of the present invention is used for the rain cover of suits and jackets, but can be applied to various products as long as it has the same shape and structure as the rain cover A. When applied to other shapes of clothing flaps such as flaps (lids) of inner pockets of outerwear, patch pockets, trousers bottom pockets, etc., the frame body (1) or inner frame (3) should be formed in a shape corresponding to the flaps. By changing the overall shape of the core plate (2) and the core plate (2), the surface press plate (4) and the liner press plate (5) having a shape corresponding to this are created. By changing the design of the shape of the frame (1), it can also be used for sewing bag-shaped shoulder boards and loose appliqués.

【Example】

 A sewing jig of the type shown in FIG. 1 was made of synthetic resin. For the outer material pressing plate (4) and the lining material pressing plate (5), a material with a fine grid-like groove pattern was used to prevent slippage. The base material pressing plate (4) and the lining material pressing plate (5) have a thin base portion (15) so that they can be bent and bent. The body is 150 mm wide and 95 mm long, with a total thickness of 7 mm. The frame body (1) had a thickness of 5 mm and a width of 10 mm.

The inner frame (3) was made to have a width of 5 mm, and the small gaps (12) and (13) were each made to have a width of 2 mm. The ear piece (21) of the core plate (2) has a sharp rounded tip.

[0035]

[Effect of the invention]

 The sewing jig according to the present invention is configured and used as described above, and has the following unique technical effects.

In conventional sewing, there is no slack on the front side of the dress material, and a slack is formed on the back side of the dress material, so that both ends of the rain lid may warp back to the front side. In the sewing jig of the present invention, the rain cover is warped to the lining side by allowing sufficient looseness on the front side of the dress material, and the inside shape of the seam has a stable shape with roundness.

In the sewing jig of the present invention, since the wavy surplus portion can be formed evenly on the periphery by the core plate and the frame body, it is possible to sufficiently loosen even a thick cloth. In particular, since the ear pieces are projected on the right and left corners of the core plate, the rounded part can create a natural curve.

The sewing jig according to the present invention has a structure in which the core plate is inserted into the inner frame, and a desired wavy shape can be imparted to the outer material by the number of the inner frames provided. The size of the looseness can be easily and arbitrarily designed.

Further, the sewing jig according to the present invention has a structure in which the core plate is inserted into the frame body. Therefore, with the frame body in the middle, the front surface pressing plate and the backing material pressing plate are superposed on the front side and the back side, respectively. It is possible to arrange it. It is possible to provide a combined sewing jig for the left and right rain lids with one sewing jig.

As described above, the sewing jig of the present invention is an excellent device capable of imparting looseness to the outer surface of the rain cover evenly during sewing.
