Description

  The present invention provides a seam allowance line forming assist for assisting in forming a seam allowance defining line for defining an allowance using a template having an outer peripheral edge for forming a finish line according to a design. The present invention relates to a seam allowance line forming auxiliary set including the member and the auxiliary member.

  When a tapestry, a pouch, a cushion, a bed cover, or the like is manufactured by quilting or patchwork, an operator first prepares a template having a shape corresponding to a desired design. This template is for assisting in drawing a desired design on a fabric using a writing instrument (for example, Chacopel (trademark of Clover Co., Ltd., the same shall apply hereinafter) and pencil). There are some that do not take into account the seam allowance. When a desired design is drawn on a fabric using a template with a seam allowance added, a finish line (border line) can be drawn on the fabric, although a seam allowance line (cutting reference line) can be drawn appropriately. I can't draw. In such a case, it is necessary to work in anticipation of the finish line in anticipation of the range of the seam allowance depending on the experience and sense of the operator. Therefore, when the worker is a beginner or the like, it is difficult to accurately assume an ideal finish line, and thus it is difficult to appropriately form a desired design. On the other hand, when a desired design is drawn on a fabric using a template that does not take into account a seam allowance, a finish line can be appropriately drawn on the fabric, but a seam allowance prescribed line cannot be drawn. In such a case, it is necessary to anticipate the seam allowance range according to the experience and sense of the operator and perform the work assuming a seam allowance line. Therefore, if the worker is a beginner or the like, it is difficult to accurately assume an ideal seam allowance line, so it is difficult to secure an appropriate seam allowance, and an appropriate seam allowance rule Since it is necessary to perform the cutting operation without drawing a line, it is more difficult to perform an appropriate cutting operation, and the working efficiency is reduced. From the above, even if the worker is a beginner or the like, in order to accurately form a desired design and perform the work more efficiently, both the finished line and the allowance line are appropriately drawn on the fabric. It is desirable.

  Therefore, as a method for properly drawing both the finishing line and the sewing allowance prescribed line on the fabric, a method of using two templates, a template that takes into account the seam allowance and a template that does not take into account the seam allowance. Can be considered. However, a template is usually created by an operator according to a desired design, and it takes a lot of labor to create one template. Accordingly, it is more time-consuming and less efficient to prepare two templates for each production. It is also difficult to properly position the two templates.

  Therefore, as a method for drawing both the finish line and the seam allowance defining line on the fabric using one template, the seam allowance defining line forming auxiliary member (hereinafter referred to as “frame”) 8 shown in FIGS. 8 and 9 is used. There is a way to use. The top 8 has a through-hole 81 for inserting the writing tip of the writing instrument P, and rolls along the outer peripheral edge 91 of the template 9 including an outer peripheral edge 91 for forming a finish line FL according to a desired design. It is a disk-shaped member to be moved. Therefore, according to this method, the finish line FL can be drawn by moving the writing tip of the writing tool P along the outer peripheral edge 91 of the template 9, and the writing tip of the writing tool P is inserted into the through hole 81. By allowing the piece 8 to roll along the outer peripheral edge 91 of the template 9, a seam allowance defining line NL can also be drawn.

  However, when the piece 8 rolls along the outer peripheral edge 91 of the template 9, if rattling (relative movement in the thickness direction (arrow AB direction) of the template 9) occurs due to the unevenness of the fabric C or the like, Since the frame 8 is easily detached from the outer peripheral edge 91 of the template 9, it is necessary to rearrange the frame 8 at a predetermined position each time, and work efficiency is poor. In particular, this problem becomes significant when a template 9 having a relatively thin thickness is used to facilitate processing into a shape according to a desired design.

  The present invention has been conceived under such circumstances, and when rolling along the outer peripheral edge of a template having an outer peripheral edge for forming a finish line according to a desired design. It is an object of the present invention to provide a seam allowance line forming auxiliary member and a seam allowance forming kit including the auxiliary member that are difficult to come off from the template even if they are relatively moved in the thickness direction of the template due to unevenness of the fabric. .

  According to a first aspect of the present invention, a seam allowance line forming auxiliary member is provided. This seam allowance line forming auxiliary member includes a disk-shaped main body portion that rolls along the outer peripheral edge of the template having an outer peripheral edge according to the design, and a central through hole for inserting the writing tip of the writing instrument. And a limiting means for limiting relative movement of the main body in the thickness direction of the template.

  According to such a configuration, the sewable line defining auxiliary member is rolled along the outer peripheral edge of the template in a state where the stylus of the writing instrument is inserted into the center through hole and the stylus is in contact with the fabric. Thus, when forming the seam allowance defining line on the fabric, the relative movement of the main body portion in the thickness direction of the template due to the unevenness of the fabric can be restricted by the restricting means. Therefore, the seam allowance line forming auxiliary member is unlikely to be detached from the outer peripheral edge of the template in the thickness direction, so that a reduction in work efficiency due to the removal is suppressed.

  As a preferred embodiment, the restricting means includes a first flange provided at one end portion in the axial direction of the main body portion and a second flange provided at the other end portion in the axial direction of the main body portion. The first and second flanges are disk-shaped, and the outer diameter thereof is larger than the outer diameter of the main body portion. According to such a configuration, it is possible to limit the relative movement of the main body in the thickness direction of the template by bringing the first and second flanges having an outer diameter larger than that of the main body into contact with the outer peripheral edge of the template. . Therefore, since the seam allowance line forming auxiliary member is difficult to be separated from the outer peripheral edge of the template in the thickness direction, a reduction in work efficiency due to the detachment is suppressed.

  Preferably, the outer diameter of the first flange is larger than the outer diameter of the second flange. According to such a configuration, the contact area between the template and the first flange is made relatively large by using the first flange having a relatively large outer diameter in contact with a member for forming a seam allowance line such as a fabric. It can be secured. Therefore, it is possible to more effectively suppress the rising of the seam allowance line forming target member (relative movement upward in the thickness direction of the template) due to unevenness of the seam allowance line forming target member. Further, the difference in outer diameter between the first flange and the second flange causes the outer diameter of the first and second flanges to be between the first flange and the second flange as compared to the case where the outer diameters are substantially the same. The outer periphery of the template can be guided more easily. Accordingly, it is possible to increase the work efficiency when forming the seam allowance defining line.

  Preferably, the outer peripheral part of the first flange and / or the outer peripheral part of the second flange is provided with a taper surface, and the taper surface increases in the direction away from the main body part in the thickness direction of each flange. Displaces radially outward of the flange. According to such a configuration, it is possible to secure a larger template inlet between the first flange and the second flange than when the tapered surface is not provided. Therefore, it is possible to more easily guide the outer peripheral edge of the template between the first flange and the second flange, and it is possible to increase the work efficiency when forming the seam allowance defining line.

  Preferably, the thickness dimension of the main body is substantially the same as the thickness dimension of the outer peripheral edge of the template. According to such a configuration, the relative movement of the main body portion in the thickness direction of the template can be almost eliminated. Therefore, since the seam allowance line forming auxiliary member is more difficult to be detached from the outer peripheral edge of the template in the thickness direction, a reduction in work efficiency due to this disengagement is further suppressed. Further, rattling of the writing instrument (relative movement in the thickness direction of the template) due to relative movement of the main body portion is suppressed, and therefore it is possible to more appropriately form a seam allowance defining line.

  Preferably, one end portion and / or the other end portion of the central through hole has a taper shape with a diameter reduced toward the main body portion side. According to such a structure, it becomes possible to ensure a larger insertion port for the writing instrument in the central through hole. Therefore, it is possible to more easily guide the writing tip of the writing tool to the center through hole, and it is possible to increase the work efficiency when forming the seam allowance defining line.

  According to the second aspect of the present invention, a seam allowance line forming auxiliary set is provided. This seam allowance line forming auxiliary set includes any seam allowance line forming auxiliary member disclosed in the first aspect of the present invention, and a template having an outer peripheral edge having a shape corresponding to the design. It is said. According to such a configuration, in addition to being able to achieve the same effects as those shown in the first aspect of the present invention, it is difficult for beginners to accurately form the outer periphery according to the design. In addition, since a template that is troublesome to produce is already provided, it is possible for a beginner to form a finish line and a seam allowance defining line according to a desired design more appropriately and easily.

  Preferably, the template has a plurality of through holes extending in the thickness direction. According to such a configuration, it is possible to fix the template at a predetermined position on the fabric using a town needle or the like normally used in quilting or the like. More specifically, for example, after placing the fabric on a work table into which the needle tip of the town needle can be inserted, the template is placed at a predetermined position on the fabric surface, and the town needle is placed through the through hole of the template. Further, the template can be positioned and fixed at a predetermined position on the fabric by being continuously inserted into the work table. Accordingly, it is possible to prevent the template from being displaced from a predetermined position on the fabric when forming the finish line and the seam allowance defining line, and it is possible to form the finish line and the seam allowance defining line more appropriately.

  Other advantages and features of the present invention will become more apparent from the following description of embodiments of the invention.

  A seam allowance line forming auxiliary set (hereinafter abbreviated as “auxiliary set”) S according to a preferred embodiment of the present invention will be specifically described with reference to FIGS.

  As shown in FIG. 1, the auxiliary set S includes a template 1 and a frame 2, and uses a writing instrument P to define a finishing line FL indicating the final contour of the finished shape on the fabric C and a seam allowance. This is for assisting in drawing a seam allowance defining line NL. The writing instrument P may be anything as long as it can draw the lines FL and NL on the fabric C, and examples thereof include chacopel, pencil, and ballpoint pen. Among them, the drawn lines FL and NL can be easily erased later. Possible chakopels and pencils are preferably used. Examples of the fabric C include, but are not limited to, a quilting front fabric (top fabric) for creating a Hawaiian quilt. The work table W includes an ironing table that is flexible and into which needles can be inserted.

  As shown in FIG. 2, the template 1 has an outer peripheral edge 11 and a plurality of through holes 12, and assists in drawing a finish line FL corresponding to a desired design on the fabric C using the writing instrument P. Is for.

The outer peripheral edge 11 has a shape in plan view corresponding to a desired design (not including a seam allowance). The thickness t ₁ (see FIG. 1) of the outer peripheral edge 11 is only required to allow the writing tool P to roll along the outer peripheral edge 11 while bringing the writing tip of the writing tool P into contact with the fabric C. 0.3 to 0.7 mm. Since the outer peripheral edge 11 in the present embodiment is formed in advance, even a beginner can appropriately and easily form a finished line FL and a sewing allowance defining line NL according to a desired design. As an example of a method for forming the outer peripheral edge 11 by itself, a transparent plate is placed on a pattern paper or the like on which a desired design is drawn, and the design is copied onto the plate, and then the plate is moved along the design. The method of cutting | disconnecting is mentioned. When the operator himself forms the template 1 having the desired outer peripheral edge 11 as described above, it is preferable to set the thickness dimension t ₁ to such an extent that the outer peripheral edge 11 can be easily processed with a scissors or a cutter. .

As shown in FIG. 1, the plurality of through holes 12 are provided so as to extend in the thickness direction (arrow AB direction) of the template 1. The hole diameter D1 of each through-hole 12 should just be able to insert the needle part of the town needle M which is _one of the general sewing tools, for example, is 1-5 mm. The formation position, the number of formation positions, the shape, and the like of each through-hole 12 are not limited to those shown in the present embodiment, and may be arbitrarily set as necessary for the purpose of preventing the template 1 from being displaced from the predetermined position. That's fine.

  As shown in FIGS. 3 and 4, the top 2 has a main body portion 21, a first flange 22, a second flange 23, and a center through hole 24, and the sewing allowance is applied to the fabric C using the writing implement P. It is intended to assist in drawing the standard line. The top 2 in the present embodiment is formed by combining two members, but may be integrally formed, or three or more members may be combined. Examples of the material of the top 2 include a resin having an appropriate strength (for example, polyacetal resin) or a metal (for example, brass).

The main body 21 is a disk-shaped portion that rolls along the outer peripheral edge 11 of the template 1. The thickness dimension t ₂ (see FIG. 4B) of the main body 21 is substantially the same as the thickness dimension t ₁ (see FIG. 1) of the outer peripheral edge 11. The outer radius D ₂ of the main body portion 21 is substantially the same as the distance (seam margins width) of the finish line FL and seam allowances defining line NL, for example, 2 to 5 mm. As shown in FIG. 1, the main body 21 in the present embodiment fits a first annular portion 211 that is continuous with the first flange 22 and a second annular portion 212 that is continuous with the second flange. However, the present invention is not limited to this. For example, the first annular portion 211 and the second annular portion 212 in FIG. 1 may be integrated. In addition, the thickness dimension t ₂ in the present embodiment is substantially the same as the thickness dimension t ₁ of the outer peripheral edge 11, but is not limited thereto, and may be arbitrarily set to a thickness dimension t ₁ or more.

As shown well in FIG. 4B, the first flange 22 is provided at one end portion (the end portion in the arrow B direction) of the main body portion 21 in the axial direction (the arrow AB direction). It is a concentric disk-shaped part. A tapered surface 221 is provided on the outer peripheral portion of the first flange 22. The tapered surface 221 increases toward the arrow B direction in the thickness direction of the first flange 21 (arrow AB direction) is configured so as to be displaced radially outwardly of the first flange 22, the angle E ₁ is For example, 15 to 45 degrees. Maximum outer diameter D ₃ of the first flange 22 is the maximum outer diameter D ₄ or more of the second flange 23 to be described later, for example, 15 to 20 mm. In this way, by making the maximum outer diameter D ₃ of the first flange 22 relatively large, a relatively large contact area between the template 1 and the first flange 22 can be secured, and in addition, Due to the difference in outer diameter between the second flange 23 and the first flange 22, the outer peripheral edge 11 of the template 1 can be guided more easily between the first flange 22 and the second flange 23.

The second flange 23 is provided at the other end portion (the end portion on the arrow A direction side) in the axial direction (arrow AB direction) of the main body portion 21 and is a disc-shaped portion concentric with the main body portion 21. A tapered surface 231 is provided on the outer peripheral portion of the second flange 23. The taper surface 231 is configured to displace outward in the radial direction of the second flange 23 toward the direction of arrow A in the thickness direction (arrow AB direction) of the second flange 23, and the angle E ₂ is For example, it is 45 to 75 degrees. Maximum outer diameter D ₄ of the second flange 23 is, for example, 10-15 mm.

The center through-hole 24 is a through-hole centering on the axis of the first flange 22, the main body portion 21, and the second flange 23, and has a configuration in which the writing tip of the writing instrument P (see FIG. 1) can be inserted. . The central through-hole 24 has a circular cross-sectional shape perpendicular to the arrow AB direction, and one end thereof (the end on the arrow B direction side) has a tapered shape with a diameter decreasing toward the arrow A direction, and the other end. The (arrow A direction side edge part) is a taper shape diameter-reduced toward the arrow B direction. By providing such a taper, it is possible to secure a larger insertion port for the writing instrument P in the central through hole 24, so that the writing tip of the writing instrument P can be guided to the central through hole 24 more easily. . The hole diameter D _{5 at} the intermediate portion of the center through hole 24 is, for example, 1.5 to 3.0 mm, and the maximum hole diameter D ₆ of the taper at one end and the other end of the center through hole 24 is, for example, 2.5 to 4. 0.0 mm. Further, the taper angle E ₃ at one end and the other end of the central through hole 24 is, for example, 15 to 45 degrees.

  Below, with reference to FIG.1, FIG.5 and FIG.6, the operation | movement at the time of drawing the finishing line FL and the seam allowance line NL on the fabric C using the auxiliary set S and the writing implement P is demonstrated. In the present embodiment, as a tool for assisting the positioning and fixing of the template 1 of the auxiliary set S, a machi needle M and a work table W into which the needle tip of the machi needle M can be inserted are used.

  First, as shown in FIG. 5A, the fabric C is placed on the work table W. In addition, from the viewpoint of simplifying the drawing, the drawing is depicted as being placed in a state where there is no overlapping of the fabric, but may be placed in a folded state as necessary.

Next, as shown in FIG. 5 (b), after placing the template 1 at a predetermined position of the cloth C placed on the work table W, the gusset M is passed through the through holes 12 of the template 1 to form the cloth. C and work table W are continuously inserted. Thereby, since the template 1 can be positioned and fixed with respect to the fabric C, the template 1 can be prevented from being displaced from the predetermined position. Further, the fixed state of the template 1 is further stabilized by adjusting the insertion angle E ₄ of the town needle M so that the town needle M is in contact with the two points of one end and the other end of the through hole 12 in the direction of the arrow AB. can do.

  Next, as shown in FIG. 6A, the writing tip of the writing instrument P is slid along the outer peripheral edge 11 of the template 1 positioned and fixed while the writing tip of the writing instrument P is brought into contact with the fabric C. As a result, a finish line FL corresponding to a desired design can be drawn on the fabric C.

  Next, as shown in FIG. 6B, the main body portion 21 of the top 2 is brought into contact with the outer peripheral edge 11 of the template 1 positioned and fixed while the first flange 22 of the top 2 is in contact with the fabric C. Thus, it is assumed that the top 2 can roll along the outer peripheral edge 11.

  Next, as shown in FIG. 1, the writing tool P is inserted in the direction of the arrow B with respect to the central through hole 24 of the frame 2, and the frame 2 is placed on the outer peripheral edge 11 with the writing tip in contact with the fabric C. Roll along. Thereby, the seam allowance defining line NL can be drawn on the fabric C at a position separated from the finished line FL by the outer radius R of the main body 21 of the top 2. That is, by adjusting the outer radius R of the main body 21, the seam allowance defining line NL can be appropriately drawn around the finish line FL with a desired seam allowance width therebetween. Further, when drawing the seam allowance defining line NL, even if the main body 21 of the top 2 is relatively moved in the arrow AB direction due to the unevenness of the fabric C, the template 1 is in contact with the flanges 22 and 23. This relative movement is limited. As described above, the finish line FL and the seam allowance defining line NL are appropriately and efficiently formed on the fabric C.

  While specific embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  For example, instead of the first flange 22, a structure as shown in FIG. 7 is used as a restricting means for restricting the main body 21 of the top 2 from moving relative to the outer peripheral edge 11 of the template 1 in the arrow AB direction. You may make it provide limiting part 22 'which has. The limiting portion 22 ′ has an annular portion 222 concentric with the main body portion 21 and a plurality of support portions 223 extending from the main body portion 21 to the annular portion 222 outward in the radial direction of the main body portion 21. According to such a configuration, since the contact area with the fabric C or the like is reduced, the frictional resistance when rolling along the outer peripheral edge 11 of the template 1 can be reduced. Therefore, the top 2 'can be rolled more smoothly than the top 2, so that the work efficiency can be further improved and the weight can be reduced.
