In manufacturing the decorative part having the aforementioned configuration, it is necessary to sew the suture position fixing member to the skin with the decorative suture. However, it is difficult to sew the stitch position fixing member formed in a linear shape and having a small width to the skin with the decorative stitch.
Disclosure of Invention
An object of the present technology described herein is to provide a jig for manufacturing a decorative stitch for sewing a stitch position fixing member to a skin with a decorative stitch and maintaining high quality and improving operability at the time of sewing.
In order to solve the above problems, a jig for making a decorative stitch according to the present invention is used in a process of manufacturing a decorative part including a base member, a skin covering the base member, a decorative stitch made on a surface of the skin, and a stitch position fixing member formed in a linear shape extending along the decorative stitch and sewn with the decorative stitch to a back surface of the skin and mounted to the base member to fix a position of the decorative stitch with respect to the base member, the jig for making a decorative stitch holding the stitch position fixing member and the skin when sewing the stitch position fixing member to the skin with the decorative stitch. The clamp for manufacturing the decorative stitching comprises: a base portion made of a magnetic material and including a fitting groove in which the suture position fixing member is fitted; a cover member made of a magnetic material and including a slit (slit) extending along a shape of the decorative stitching and through which a needle of a sewing machine is inserted; and a magnet fixed to the base and the cover member. The suture position fixing member is fitted to the fitting groove of the base, and the skin is disposed at a predetermined position of the base, and in this state, the cover member is fixed to the base by the magnetic force of the magnet in such a manner that the suture position fixing member and the skin are sandwiched between the base and the cover member.
In the jig for manufacturing a decorative stitch having the above-described configuration, the horizontal movement of the stitch position fixing member is prevented by the fitting groove of the base portion. The skin is carried on the suture position fixing member and the base and the cover member is fixed to the base with a magnetic force of the magnet such that the suture position fixing member is sandwiched between the base and the skin is sandwiched between the base and the cover member. That is, the jig for manufacturing a decorative stitch having the above-described configuration prevents displacement of the skin with respect to the stitch position fixing member, and can maintain high quality of the decorative stitch. With the jig for making decorative stitches having the above-described configuration, the skin is sandwiched between the base and the cover member, and the portion of the skin to be made decorative stitches can be tightened (tension) by the jig, and therefore, the sewing machine does not need to include a function of pressing the skin. That is, the sewing operation is performed in a state where the skin and the part of the suture position fixing member to be sewn are pressed by the jig for making a decorative suture. Therefore, the decorative stitches are made on the skin and the stitch position fixing member without applying vibration to the skin and the fixing member while keeping the skin and the fixing member in a stable state. Therefore, high quality can be maintained. Further, the suture position fixing member and the skin can be easily fixed by making the jig for a decorative suture, and the workability of the sewing operation of sewing the suture position fixing member to the skin with the decorative suture can be improved.
In the above configuration, the magnet fixed to the base portion may be arranged in the vicinity of the fitting groove, and the magnet fixed to the cover member may be arranged in the vicinity of the slit.
In the jig for making a decorative stitch having the above-described configuration, the position where the magnet is arranged is restricted, and the magnet is arranged near and along the portion where the decorative stitch is to be made. According to the jig for making decorative stitching having the above-described configuration, displacement of the decorative stitching to be made on the portion of the skin is surely prevented.
In the above-described configuration, the magnet may be arranged only inside the skin in a width direction of the fitting groove or the slit with respect to the fitting groove or the slit in a region of the fitting groove or the slit where the suture position fixing member is arranged.
With the jig for making decorative stitches having the above-described configuration, the magnet is arranged only on the inner side (away from the outer edge) of the skin with respect to the portion of the skin where the decorative stitches are to be made. In other words, the magnet is not arranged on the outer edge side of the skin with respect to the portion of the skin where the decorative stitch is to be made. The jig for making a decorative stitch having the above-described configuration allows the skin to stretch when the needle of the sewing machine penetrates the skin and hardly generates wrinkles on the skin and further improves the quality of the decorative stitch.
In the above configuration, the decorative stitching may be formed in a shape having a curved portion at which an extending direction of the decorative stitching changes, and each of the fitting groove and the slit may have a curved portion corresponding to the shape of the decorative stitching. One of the magnets may be arranged near a curved portion of the fitting groove of the base portion, and the other of the magnets may be arranged near a curved portion of the slit of the cover member such that the one magnet and the other magnet overlap each other.
When forming the decorative stitching, displacement and buckling may be caused at the bends. However, according to the jig for manufacturing a decorative stitch having the above-described configuration, the magnet disposed in the vicinity of the bent portion of the base and the magnet disposed in the vicinity of the bent portion of the cover member overlap each other to be in contact. Therefore, the skin is firmly fixed, and thus displacement or wrinkles are hardly caused in the sewing operation.
In the above configuration, the magnets other than the one magnet fixed to the portion of the base portion near the curved portion of the fitting groove and the other magnet fixed to the portion of the cover member near the curved portion of the slit may not overlap each other.
According to the jig for manufacturing a decorative stitch having the above-described configuration, the magnets arranged at the portions of the decorative stitch other than the bent portion do not overlap each other. The fixing force of the cover member with respect to the base is not excessively strong, and the cover member can be easily attached to and detached from the base while maintaining the fixing force of the cover member with respect to the base.
In the above configuration, the jig for manufacturing a decorative stitch may further include: a hinge swingably connecting the cover member to the base; and a stopper member that prevents the swinging of the cover member so that the cover member does not excessively open with respect to the base.
In the jig for making a decorative stitch having the above configuration, the lid member is configured to be opened and closed with respect to the base portion using a hinge. According to this structure, the cover member is easily fixed to the base. Further, in the jig for manufacturing a decorative stitch having the above-described configuration, the cover member can be stopped in the open state at a certain angle by the stopper member. Since the cover members include the slits, portions of the cover members that oppose each other and sandwich the slits therebetween may receive a force caused by the weight of the cover members when the cover members are opened and closed. If the cover member is opened too wide, a portion near the slit may be deformed by the weight of the cover member. According to the clip for manufacturing a decorative stitching having the above-described configuration, the stopper member prevents the cover member from being opened too widely, and therefore the cover member is hardly deformed.
In the above configuration, the stitch position fixing member may include a stitch portion that extends along the decorative stitch and on which the decorative stitch is made, and a protruding portion that protrudes toward the base member, and the protruding portion is fitted to the base member and attached to the base member. The fitting groove may include a receiving portion that receives the protruding portion with a space in a direction in which the decorative stitching extends.
The suture position fixation member may be molded in such a manner that the protrusions are not formed at the correct positions with respect to the suture portion. In particular, in a suture position fixing member made of resin and formed by resin injection molding, such displacement may be caused. According to the jig for manufacturing a decorative stitching having the above-described structure, the protruding portion is reliably received in the receiving portion of the fitting groove of the base portion. Therefore, displacement that may be caused when molding the suture position fixing member can be fixed.
In the above configuration, the base may include a base main body having a flat plate shape, and a pair of guides mounted to an upper surface of the base main body with a space therebetween, and the pair of guides may form the fitting groove.
According to the jig for manufacturing decorative stitching having the above-described configuration, the skin is sandwiched between the upper surfaces of the pair of guides and the back surface of the cover member. That is, the skin is held along the portion of the skin where the decorative stitch is to be made, and therefore, displacement is not caused in the portion of the skin where the decorative stitch is to be made.
In the above configuration, the fitting groove and the slit may be located between the row of the magnets and an edge of the skin near the decorative stitching to be made.
According to the jig for manufacturing a decorative stitch having the above-mentioned configuration, the skin is allowed to stretch and wrinkles are hardly generated on the skin when the needle of the sewing machine penetrates the skin, and the quality of the decorative stitch is further improved.
In the above configuration, the magnet fixed to the base and the magnet fixed to the cover member may be alternately arranged.
According to the jig for making decorative stitches having the above-described configuration, the skin is stably held between the base and the cover member, and displacement of decorative stitches to be made on the portion of the skin is surely prevented.
In the above configuration, the opening width of the slit may be smaller than the opening width of the fitting groove.
According to the jig for making a decorative stitch having the above-described configuration, the needle for forming the decorative stitch can be guided along the slit without displacement at the portion of the skin where the decorative stitch is to be made.
According to the present invention, there is provided a jig for manufacturing a decorative stitch, which maintains high quality and improves workability in sewing when sewing a stitch position fixing member to a skin with a decorative stitch.

Detailed Description
Embodiments of the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the following embodiments, but may be changed or improved based on the knowledge of those skilled in the art.
The jig for making trim stitches according to the embodiment of the invention is used in the process of manufacturing the door trim 10 shown in fig. 1. The door trim 10 will be explained first. The door trim 10 is a vehicle interior side portion of a vehicle side door and is mounted to a door inner panel from the vehicle interior side. The door trim 10 mainly includes a trim panel 11 having a substantially quadrangular shape, and various functional components such as an inner handle 12, an armrest 13, a door pocket 14, and a speaker grille 15 mounted to the trim panel 11.
The garnish panel 11 includes a plurality of panel members joined to each other, and includes an upper panel 20, a lower panel 21, and a garnish panel 22. The inner handle 12 is mounted on the front side of the vehicle with respect to the trim panel 22. The armrest 13 is mounted on the trim panel 22. The door pocket 14 and the speaker grille 15 are mounted to the lower plate 21.
< Structure of decorative Member (Upper plate) >
Each of upper panel 20 and trim panel 22 includes a base member and a skin, wherein the skin includes trim stitching and is affixed to the base member. The upper plate 20 and the decorative plate 22 are decorative members used for manufacturing the jig for decorative stitching according to the present embodiment. The configuration of the upper plate 20, which is one of the decorative members, will be explained in detail with reference to fig. 2 to 5.
As shown in fig. 1, the upper plate 20 has an elongated shape extending in the vehicle front-rear direction, and has a lower end portion projecting downward at a vehicle rear side portion thereof. The upper panel 20 includes a plate-shaped base member 30 made of a synthetic resin material such as polypropylene or the like, and a skin 31 covering a front face (a vehicle interior side surface, an appearance face, a lower side in fig. 4) of the base member 30. The material of the base member 30 is not necessarily a synthetic resin material, and may be a mixture of plant fibers (e.g., kenaf, solar hemp, flux, sisal) and a synthetic resin. As shown in fig. 1, decorative stitches S (hereinafter may be simply referred to as stitches S) are made on the surface of the skin 31. On the base member 30 covered with the skin 31, a row of stitches S extends along the lower edge of the base member 30.
The upper plate 20 includes a suture position fixing member 32 (hereinafter may be simply referred to as a fixing member 32) for fixing the position of the decorative suture S with respect to the base member 30. The fixing member 32 is an elongated member made of synthetic resin such as polypropylene or the like and extending along the decorative sewing line S. As shown in fig. 2, the fixing member 32 is fitted in a recess 30a formed along the lower edge of the base member 30. When the fixing member 32 is fitted in the recess 30a of the base member 30, the surface of the base member 30 and the surface of the fixing member are in the same plane. As shown in fig. 3, the fixing member 32 includes a suture portion 32a and a protruding portion 32 b. The suture portion 32a extends along the decorative suture S, and the decorative suture S is made on the suture portion 32 a. The protruding portion 32b protrudes from the back surface of the suture portion 32 a. The base member 30 includes a through hole 30b in the recess 30a corresponding to the protrusion 32 b. The protruding portions 32b of the fixing members 32 protrude toward the base member 30, and the respective through holes 30b are inserted from the front side so that the fixing members 32 are fitted in the base member 30. The projection 32b includes a pair of projections 32c, 32 d. One of the projections 32c has a stopper, and the projection 32c can be blocked by the hole edge of the through hole 30b on the back surface side of the base member 30.
The fixing member 32 disposed on the back surface of the skin 31 along the decorative seam S and the skin 31 are sewn together with the decorative seam S. Then, the fixing member 32 is mounted on the base member 30 in the following manner: so that the protrusions 32b are fitted in the respective through holes 30b of the base member 30 while the skin 31 is attached to the surface of the base member 30. According to this configuration, the position of the decorative stitching S on the upper panel 20 with respect to the base member 30 is fixed.
< schematic Structure of jig for producing decorative Sewing line >
As described above, in manufacturing the upper plate 20 which is a decorative part and has the above-described configuration, the stitch position fixing member 32 must be sewn on the skin 31 with the decorative stitch S. However, it is difficult to sew the stitch position fixing member 32 (which is formed in a linear shape and has a small width) on the skin 31 with the decorative stitches S. In particular, in the sewing of the decorative stitching S, it is difficult to maintain high quality and improve the operability of the sewing operation. In this regard, the jig 50 for making a decorative stitch according to the present embodiment of the present invention is used in the process of manufacturing the upper plate 20. When the stitch position fixing member 32 is sewn to the skin 31 with the trim stitches S, the skin 31 and the stitch position fixing member 32 are held using the jig 50 for making trim stitches. Therefore, high quality can be maintained and workability of the sewing operation and ultimately workability of manufacturing the upper plate 20 can be improved.
As shown in fig. 6, a jig 50 for making a decorative stitch according to the present embodiment (hereinafter may be simply referred to as a jig 50) includes a base 51 and an upper cover (cover member) 52. The base 51 and the upper cover 52 are magnetic members (made of, for example, stainless steel). The base portion includes a fitting groove 51a in which the fixing member 32 is fitted. Specifically, as shown in fig. 6, the base 51 mainly includes a base main body 60, and the base main body 60 is a rectangular flat plate. As shown in fig. 7, the base main body 60 includes a base side slit 60a extending along the decorative stitching S or along the advancing direction of the sewing needle N. The distal end of the needle N is inserted into the base-side slit 60 a. The base 51 includes a pair of seats 61 and a pair of positioning members 62. The base 61 is fixed to the upper surface of the base main body 60 and extends along the base-side slit 60 a. The fixing member 32 is placed on the base 61. The positioning member 62 is fixed to the upper surfaces of the pair of bases 61 and extends along the bases 61. The position of the fixing member 32 in the width direction is fixed by the positioning member 62. The fitting groove 51a is formed by a pair of bases 61 and a pair of positioning members 62. The pair of bases 61 and the pair of positioning members 62 function as a pair of guides 63. The space between the opposing bases 61 is smaller than the space between the opposing positioning members 62. According to this configuration, the opposite portions of the base 61 further protrude from the opposite edges of the positioning member 62, respectively. Therefore, a housing space is created between the opposing surfaces of the positioning member 62 and above the upper surface of the protruding opposing portion of the base 61, and the space is defined by the fitting groove 51 a. Therefore, the fixing member 32 is received in the fitting groove 51a at the projecting opposite portion of the base 61.
On the other hand, the upper cover 52 mainly includes an upper cover main body 70, and the upper cover main body 70 is a plate member shaped substantially along the shape of the decorative stitching S. The upper cover main body 70 includes a hole 70a extending substantially along the decorative sewing line S to be made. The upper cover 52 includes a guide member 71, and the guide member 71 is fixed to a lower surface (back surface) of the upper cover main body 70 in such a manner as to cover a part of the hole 70 a. The guide member 71 includes an upper cover side slit 71a, and the upper cover side slit 71a extends along the decorative stitch S to be made or along the advancing direction of the sewing needle N. The hole width of the upper cover side slit 71a is smaller than the hole width of the hole 70 a. Therefore, the needle N is inserted through the upper cover side slit 71a and guided in the advancing direction by the upper cover side slit 71 a.
The upper cover 52 is connected to the base 51 in a swingable manner with three hinges 80, and the upper cover 52 is opened and closed with the hinges 80. The base 51 includes a stop member 81 having a gate shape behind the hinge 80 and the stop member 81 extends vertically from the base 51. As shown in fig. 8, the stopper member 81 is configured to prevent the upper cover 52 from further swinging in the opening direction. That is, the clip 50 of the present embodiment restricts the opening and closing movement of the upper cover 52 to the minimum as required, and improves the operability of setting and removing the skin 31 and the fixing member 32. As shown in fig. 6, since the upper cover 52 includes the upper cover side slits 71a, portions of the upper cover 52 that oppose each other and sandwich the upper cover side slits 71a therebetween may receive a force caused by the weight of the upper cover 52 when the upper cover 52 is opened and closed. If the upper cover 52 is opened too wide, a portion near the upper cover side slit 71a may be deformed by the weight of the upper cover 52. According to the clip 50 of the present embodiment, the stopper member 81 prevents the upper cover 52 from being opened too widely, and therefore the upper cover 52 is hardly deformed.
Each of the base 51 and the upper cover 52 includes a magnet 82 made of a permanent magnet. The magnet 82 is fixed to each of the base 51 and the upper cover 52. The upper cover 52 is fixed to the base 51 using a magnetic force generated between the magnet 82 fixed to the base 51 and the magnet 82 fixed to the upper cover 52, or between the magnet 82 and the base 51 or the upper cover 52 made of a magnetic member. The jig 50 according to the present embodiment is configured to hold the skin 31 and the fixing member 32 between the base 51 and the upper cover 52 using magnetic force.
< characteristics of the suture step for producing a decorative suture and the clip for producing a decorative suture >
Next, a sewing step of sewing the skin 31 and the fixing member 32 with the decorative stitching S in the process of manufacturing the upper plate 20 as the decorative member will be described, and features of the jig 50 for manufacturing decorative stitching of the present embodiment will be described.
First, as shown in fig. 9, the upper cover 52 is opened (the upper cover 52 is not shown in fig. 9), and the fixing member 32 is fitted in the fitting groove 51a of the base 51. As shown in fig. 6, the fitting groove 51a includes the receiving portions 51a1, and each of the receiving portions 51a1 is wider than the other portions of the fitting groove 51 a. The fixing member 32 is fitted in the fitting groove 51a such that the protruding portions 32b are placed in the respective receiving portions 51a 1. As shown in fig. 10, the dimension of the receiving portion 51a1 in the extending direction of the fitting groove 51a is larger than the dimension of the protruding portion 32b of the fixing member 32. Therefore, the housing portion 51a1 has an extra space in the extending direction (the extending direction in which the row of decorative stitching extends). The fixing member 32 is made by injection molding, and thus an error may be generated at the time of molding. However, in the clip 50 according to the present embodiment, each protruding portion 32b of the fixing member 32 can be surely received in the receiving portion 51a1 having an extra space. Therefore, the jig 50 can cope with an error that may be generated when the fixing member 32 is molded.
Next, as shown in fig. 11, the skin 31 is set on the base 51. The base 51 comprises a positioning member 83 for positioning the skin 31. Each positioning member 83 includes a pin 83a protruding upward. The skin 31 includes locating holes 31a (see fig. 3) near its outer edge. The pins 83a of the positioning member 83 are fitted in the respective positioning holes 31a of the skin 31 in such a manner that the skin 31 is set at a predetermined position. Each positioning member 83 mounted on the base 51 is capable of adjusting the position of the positioning member 83 with respect to the extending direction and the rotating direction of each positioning member 83. It is possible to cope with an error (fix) that may be caused when the skin 31 is molded.
Next, as shown in fig. 12, the skin 31 and the fixing member 32 are held between the base 51 and the upper cover 52 by closing the upper cover 52. As described previously, the magnet 82 is fixed to each of the base 51 and the upper cover 52, and the base 51 and the upper cover 52 are fixed to each other using the magnetic force of the magnet 82. As shown in fig. 6, among the magnets 82, a magnet 82a fixed on the base 51 is arranged next to the guide members 63 (on the outer sides of the pair of guide members 63), and a magnet 82b (shaded in fig. 6) fixed on the upper cover 52 is arranged next to the guide members 71 (on the outer sides of the pair of guide members 71). That is, the magnet 82 is arranged near the portion where the decorative stitch S is to be made and along the decorative stitch S to be made. In the closed state in which the upper cover 52 is closed, the magnets 82a fixed to the base 51 and the magnets 82b fixed to the upper cover 52 are alternately arranged.
As shown in fig. 12, the magnet 82 is arranged so as to sandwich each of the fitting groove 51a and the upper cover-side slit 71a with respect to the width direction of the fitting groove 51a and the upper cover-side slit 71a at both end portions of the fitting groove 51a and the upper cover-side slit 71a with respect to the extending direction. That is, two magnets are arranged on respective sides of the fitting groove 51a and the upper cover side slit 71a with respect to the width direction at respective both end portions of the fitting groove 51a and the upper cover side slit 71 a. On an intermediate portion of each of the fitting groove 51a and the upper cover side slit 71a, that is, in a region where the fixing member 32 is set, the magnet is arranged only inside the outer skin 31 with respect to the fitting groove 51a and the upper cover side slit 71a in the width direction of the fitting groove 51a and the upper cover side slit 71 a. That is, the fitting groove 51a and the upper cover side slit 71a are located between the row of magnets 82 and the edge of the skin 31 closer to the decorative stitch S to be made. The magnet 82 is not arranged on the edge side of the skin 31 with respect to the fitting groove 51a and the upper cover side slit 71 a. According to such a configuration, the clip 50 according to the present embodiment allows the skin 31 to stretch when the needle N of the sewing machine penetrates the skin 31, and hardly generates wrinkles on the skin 31.
As shown in fig. 1, a row of the decorative stitches S to be made on the skin 31 has a bent portion, and the extending direction of the decorative stitches S is changed from substantially the vehicle front-rear direction to an upward direction at the bent portion. In the jig 50 according to the present embodiment, each of the fitting groove 51a and the upper cover side slit 71a also has a bent portion according to the shape of the row of decorative stitching S. As shown in fig. 12, the base-side magnet 82a and the upper-cover-side magnet 82b overlap each other at the bent portions of the fitting groove 51a and the upper-cover-side slit 71a in plan view. The magnets 82 other than the magnet 82 disposed at the bent portion do not overlap.
When the curved portion of the row of decorative stitching S is made, displacement or wrinkles may be caused on the skin 31. According to the clip 50 of the present embodiment, the base-side magnet 82a and the upper-cover-side magnet 82b overlap each other at the bent portion, so that the skin 31 can be firmly held. Therefore, the occurrence of displacement or buckling is effectively restricted when suturing the bent portion. In the clip 50 of the present embodiment, the magnets 82 arranged at portions other than the bent portion do not overlap with each other. Therefore, the upper cover 52 may not be fixed to the base 51 more firmly, and the upper cover 52 can be opened and closed easily.
Further, in the jig 50 according to the present embodiment, the fixing member 32 fitted in the fitting groove 51a of the base 51 is covered with the skin 31, and the skin 31 is sandwiched between the base 51 and the upper cover 52. Therefore, displacement of the epidermis 31 is hardly caused. More specifically, as shown in fig. 7, in a closed state (a state in which the upper cover 52 is fixed to the base 51) in which the upper cover 52 is closed, the pair of guides 63 arranged on the upper surface of the base 51 and the pair of guide members 71 arranged on the lower surface of the upper cover 52 are in contact with each other with the skin 31 therebetween. That is, the jig 50 of the present embodiment sandwiches the skin 31 along the portion of the skin 31 where the decorative stitch S is to be made, and the skin 31 is held by the jig 50 at the portion of the skin 31 sandwiched between the hole 70a and the base-side slit 60 a. Therefore, displacement of the skin 31 can be reliably prevented.
As described above, the portion of the skin 31 where the decorative stitch S is to be made can be tightened by the jig 50 for making a decorative stitch according to the present embodiment, and therefore, the sewing machine does not need to include a function of pressing the skin 31. That is, the sewing operation is performed in a state where the skin 31 and the portion of the fixing member 32 to be sewn are pressed by the decorative stitching jig 50. Therefore, the decorative stitches S are made on the skin 31 and the fixing members 32 without applying vibration to the skin 31 and the fixing members 32 while keeping the skin 31 and the fixing members 32 in a stable state. Therefore, high quality can be maintained. Further, the fixing member 32 and the skin 31 can be easily fixed by the jig 50 for manufacturing a decorative stitch according to the present embodiment. The workability of the sewing operation of sewing the fixing member 32 to the skin 31 with the decorative sewing S can be improved.
