Description

[Technical Field]

[0001] The present invention relates to a product that uses fabric and hard material other than genuine leather, and a method for manufacturing the product; more specifically, to a product such as a key holder or pass case that uses polyurethane (PU), synthetic fiber, or artificial leather and has a main body equipped with a hard display panel with a pattern displayed in the center of the surface, and a method for manufacturing the product. [Background technology]

[0002] Traditionally, key chains and the like made of a genuine leather plate made of a hard synthetic resin such as a transparent acrylic resin, with a pattern such as a logo mark or character displayed in the center of one side, have been popular in various shapes and are used by many users.

[0003] Japanese Utility Model Application Publication No. 7-025887 discloses a key holder with the objective of providing a key holder that gives a calm and luxurious impression by combining leather and hard materials. The key holder is formed by stacking two front and back leather plates of the same shape and thickness on top of each other and sewing together their outer edges, and the main surface of the key holder is made of a leather plate having a through hole in the center. A hard display plate made of a hard synthetic resin plate such as acrylic resin on which appropriate letters, designs, etc. are engraved or embossed is fitted into the through hole, and a thin flange plate protruding from the outer edge of the back surface of the hard display plate is sandwiched between the overlapping surfaces of the front and back leather plates (Patent Document 1).

[0004] However, many of the existing genuine leather products, such as key chains, have a hard display plate sandwiched between the outer edges of the genuine leather using a sewing machine, which poses problems such as unstable positioning of the hard display plate, uneven surface of the fabric, and complicated and costly manufacturing processes.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be described in detail below based on preferred embodiments thereof. One embodiment of the present invention is a key holder 10 having a circular (round) outer shape in a planar view, as shown in Figures 1(a) and (b), and comprising: a plate-shaped core material 1 having approximately the same outer shape as the key holder 10; a surface member 2 having approximately the same outer shape as the core material 1 and having a through hole 5 in the center, fixed to one side of the core material 1; a back member 3 having approximately the same outer shape as the core material 1, fixed to the other side of the core material 1; and a hard display plate 7 having the same shape as the through hole 5 of the surface member 2, having a pattern printed on it (not shown), and fitted into the through hole 5.

[0018] The material for the fabric 12 of the front member 2 and back member 3 used in the key holder 10 is preferably a fabric with low shrinkage, in order to prevent distortion during bonding when forming the body of the key holder 10. It is also preferable to select a material that is easy to cut when cutting the outer and inner shapes of the fabric 12 from the material sheet 11 using a press mold, which will be described later. Fabrics with good adhesive properties are also preferable. In this embodiment, polyurethane (PU) is particularly preferred for the fabric 12. The fabric 12 of the front member 2 and back member 3 may also be made of synthetic fiber or artificial leather. Moreover, the front surface member 2 and the back surface member 3 are fixed to the core material 1 with an adhesive 13 .

[0019] According to this embodiment having such a configuration, the surfaces of the front member 2 and the back member 3 as fabrics are smooth, the position of the hard display board 7 is stable and does not shift, and the key holder 10 can be produced easily and inexpensively.

[0020] When manufacturing the key holder 10, a fabric 12 is used in which the portions forming the front surface member 2 having a through hole 5 in the center and the back surface member 3 are integrated via a connecting portion 4 (Fig. 1(b)). In other words, the fabric 12 is formed as an integrated body connected by the connecting portion 4 extending from a portion of the outer periphery of each of the front surface member 2 and the back surface member 3.

[0021] As shown in Figure 2, this fabric 12 is formed from a sheet 11 of PU material so as to have an outer shape that follows (corresponds to) the shape of the main body of the key holder 10 to be obtained. In particular, when forming the fabric 12 from the sheet 11, in order to improve precision, the outer shapes of the portions that integrally form the front member 2, the back member 3, and their connecting portion 4, as well as the inner shape of the through-hole 5 in the front member 2, are each punched out using a mold. At this time, the sheet 11 of the material to be used is cut to a predetermined thickness in advance so that the fabric 12 can be used as the front member 2 and the back member 3 as is.

[0022] The outer shape (peripheral shape) of the fabric 12 including the front surface member 2 and the back surface member 3 via the connecting portion 4 has a shape that is symmetrical front to back and left to right with respect to the center line (CL) in FIG.

[0023] Next, the main body 6 of the key holder is created using the fabric 12 and a backing sheet as the core material 1 corresponding to the shape of the key holder body to be obtained. At this time, as shown in Figures 1(a) and (b), the front surface member 2 that corresponds to the outer periphery of the through-hole 5 is superimposed on one surface (front side) of the backing sheet 1 and fixed with adhesive 13. Next, the back surface member 3 is bent in the direction of the arrow in Figure 1(a) with the center line CL of the connecting part 4 as the base axis, and the back surface member 3 is superimposed on the other surface (back side) of the backing sheet 1 and fixed with adhesive 13.

[0024] More specifically, the core material 1 is attached and fixed to at least a part or all of one surface of the front surface member 2 of the fabric 12 (excluding the through-holes 5) with adhesive 13. Then, the fabric 12 is folded in half along the center line of the connecting portion 4, and the surface of the core material 1 opposite the front surface member 2 is fixed to at least a part or all of one surface of the back surface member 3 of the fabric 12 with adhesive 13. See Figure 1(a) for an image of the folding process.

[0025] Here, for example, a mount such as hard paper is used as the core material 1. The thickness of the core material 1 is preferably 1.0 to 2.0 mm.

[0026] As shown in Figure 1(b), when a front surface member 2 and a back surface member 3 of fabric 12 are attached and fixed to both sides of core material 1 with adhesive 13, the main body 6 of the key holder is formed. In this way, the front surface member 2 and the back surface member 3 of fabric 12 are bonded to both sides of core material 1 so as to encase the core material 1, forming the main body 6 of the key holder. At this time, the connecting portion 4 is adjusted in advance to secure an insertion hole 8 for inserting the holder metal (such as a snap hook, not shown) of key holder 10.

[0027] Once the main body 6 is formed, the connecting portion 4 forms a holder metal insertion hole 8 extending along a portion of the outer peripheral end surface formed by the core material 1, the front surface member 2, and the back surface member 3. The holder metal is attached to this insertion hole 8 at an appropriate time before or after the formation of the main body 6 of the key holder.

[0028] Thereafter, a transparent acrylic resin with a printed design (not shown) is fitted into the through-hole 5 on the inside (central part) of the surface member 2 of the main body 6 of the key holder, as the rigid display board 7. The printed acrylic resin 7 has the same external shape as the through-hole 5 so that it can be fitted in, and is attached to the core material 1 with adhesive, double-sided tape, etc. The rigid display board 7 has the same shape as the through-hole 5, so it can be fitted snugly into the installation location.

[0029] The rigid display panel 7 used in this embodiment is made of a transparent acrylic resin. Note that the material of the rigid display panel is not particularly limited in the present invention, and may be an acrylic resin, a resin such as PC (polycarbonate), ABS, PS (polystyrene), or SBC (styrene-butadiene copolymer resin, K-resin), or may be an opaque colored material, metal, or the like.

[0030] As shown in FIG. 3(a), the rigid display board 7 placed on the surface of the key holder 10 (the surface member 2 side) is made of transparent acrylic resin with a gently convex curved surface and a flat back surface. The rigid display board 7 is printed with a design by printing P from its back side (the side that adheres to the core material 1). The design can be printed by inkjet printing, offset printing, on-demand printing, sublimation printing (transfer), silk printing, or other methods. If a material other than transparent resin, such as metal, is used as the rigid display board, the design is printed from the front side.

[0031] Examples of designs that may be displayed on the rigid display board 7 include people shown in Figures 8(a) and (b), as well as characters, idols, manufacturer logos, etc. Figure 8(a) shows an example of a design printed on a circular key holder 10 according to this embodiment, and Figure 8(b) shows an example of a design printed on a rounded rectangular key holder 20 according to another embodiment.

[0032] The rigid display plate 7 is fixed to the core material 1 at the fitting position in the through-hole 5 with adhesive or double-sided tape (not shown) so that it will not be removed from the key holder 10 after installation.

[0033] Figure 3(b) shows the back side (back member 3 side) of the main body of key holder 10. The back side of key holder 10 is flat, and this back side (back member 3) made of PU can be printed with inkjet printing or the like to display, for example, the name of a festival, event, theme park, etc. The back side may also be left plain with no printing.

[0034] To improve the appearance by hiding the PU fabric and backing, a resin is applied to the outer periphery (edge) of the key holder 10 body, forming a finished edge 14. Examples of edge treatment finishing agents include high-gloss acrylic resin water-based pigments. Forming such a finished edge 14 imparts a beautiful luster, provides strong adhesion to the edge, is highly flexible, is resistant to sun and water, and maintains its beautiful color for a long period of time.

[0035] In this manner, the key holder 10 can be manufactured. In this manner, the end faces of the key holder 10 of this embodiment are beautifully finished by edge finishing. Note that this manufacturing method shows an example of forming a circular key holder 10, and is not limited to this manufacturing method.

[0036] The key holder as a product of the present invention can have any desired shape and can be appropriately selected from key holders having various shapes. Examples of the shape of the key holder according to the present invention include a circular shape like the key holder according to the embodiment described above, as shown in Fig. 4, as well as square shapes (rectangles, etc.), shapes like sports uniforms (apparel), houses, cars (for dealers), sports movements (swings, etc.), whales, dolphins, and various shapes related to zoos, aquariums, novelties, people, MUSUC, idols, etc.

[0037] For example, in the case of uniforms, various series of sportswear shapes for soccer, rugby, baseball, etc. are available.

[0038] Another example of the process for manufacturing the key holder 10 of this embodiment is shown below, and is performed through the following steps 1, 2, and 3. In the example described above, the surface member 2 is first adhered to the core material 1, and the holder metal 9 is attached last, but the order of adhering to the core material 1 and attaching the holder metal 9 is not particularly limited, and a different order of steps is shown here.

[0039] As shown in FIG. 5, in the first step, the core material 1 is attached to the back surface member 3 of the fabric 12 that forms the key holder body by adhesive 13 applied to at least a part or the entire overlapping area.

[0040] As shown in Fig. 6, in the second step, a snap hook 9 serving as a holder metal having a notch n is attached to the connecting portion 4 of the fabric 12. When attaching the snap hook 9, the connecting portion 4 is hooked onto the notch n. Note that in another embodiment of the present invention, a holder metal without a notch can also be used.

[0041] Next, as shown in Figure 7, in the third step, adhesive 13 is applied to at least a part or the entire overlapping area of ​​the surface member 2 (the part that will become the window frame) of the fabric 12, and the surface member 2 with this adhesive 13 applied is folded in half along the center line of the connecting part 4 where the snap hook 9 is located, and adhered to the core material 1.

[0042] Then, a transparent acrylic resin (hard display board) 7 with a printed design is fitted into the through hole 5 of the surface member 2, and the contact points with the core material 1 are adhered and attached, thereby completing the key holder 10.

[0043] In the above-described embodiment, a circular key holder 10 was described, but other embodiments of key holders having other shapes can also be manufactured from symmetrical fabric with surface and back members corresponding to the shape of the key holder, and the description of the circular key holder described above can be applied as appropriate.

[0044] Another embodiment of the product of the present invention provides a pass case 30 that can be used as a commuter pass holder, as shown in Figures 9(a) and (b). To clearly explain the structure of pass case 30, Figure 9(a) shows the pocket side of pass case 30 (the back side of the hard display board with a printed design, not shown) (left figure) and the side of pass case 30 (right figure), and Figure 9(b) shows the hard display board side with a printed design, not shown, of pass case 30 (in the figure, the surface with surface member 32 and through-holes 35) (left figure) and a perspective view of pass case 30 with each component separated (right figure).

[0045] As shown in FIGS. 9(a) and 9(b), the pass case according to this embodiment is a pass case 30 having a rectangular shape (vertically long rectangle with rounded corners), a plate-shaped core material 31 having substantially the same outer shape as the pass case 30; a surface member 32 having substantially the same outer shape as the core member 31, a through-hole 35 provided in the center, and fixed onto one surface of the core member 31; a back surface member 33 having substantially the same outer shape as the core material 31 and fixed to the other surface of the core material 31; a hard display plate (not shown) having the same shape as the through-hole 35 of the surface member 32, having a pattern printed thereon, and fitted into the through-hole 35; The front surface member 32 and the back surface member 33 are made of polyurethane (PU), synthetic fiber, or artificial leather, and are fixed to the core material 31 with adhesive 34. A pocket member 36 having a transparent resin 40 and allowing the inside to be seen is attached to the surface of the back member 33 opposite to the core member 31. The pocket member 36 is made of the same material as the front member 32 and the back member 33 .

[0046] According to this embodiment having such a configuration, the surfaces of the front member 32, the back member 33 and the pocket member 36 as fabric are all smooth, the rigid display board is stable without misalignment, and the pass case 30 also has functions such as a commuter pass holder, making it possible to create the pass case 30 easily and inexpensively.

[0047] Additionally, an insertion hole 38 for inserting a metal holder and a snap hook 39 serving as the metal holder are attached to the upper center of the pass case 30. In this way, the pass case 30 of this embodiment also functions as a key holder or the like.

[0048] The pass case 30 of this embodiment differs from the key holder 10 of the previous embodiment in that, rather than folding a single piece of fabric in half, separate pieces of fabric are used for the front and back members 32 and 33, which are attached to the core material 31, with insertion holes 38 attached separately above them (see the right diagram in Figure 9(b)). Furthermore, PVC (polyvinyl chloride) is preferably used as the transparent resin 40, and the pocket member 36 containing this resin has its outer periphery and the surrounding area of ​​the PVC 40 (shown by the dotted lines in the figure) bonded together, as shown in Figures 9(a) and 9(b). This securely fastens the front and back members 32 and 33 to the core material 31 and allows the pass case 30 to fully function as a pocket. The insertion holes 38 and holder metal 39 are optional and are not required.

[0049] The outer periphery (edge ​​surface) of the pass case 30 is coated with edge-hiding resin to improve the appearance by hiding the PU fabric and backing paper, and is neatly finished as an edge-finished edge surface 37.

[0050] The pass case 30 differs from the key holder 10 described above in terms of its function, shape and manufacturing method, but the materials of the surface member 32 and back member 33, which form the base, the holes 35, the core material 31, the adhesive 34, the insertion holes 38, the holder metal 39, the hard display board with a printed pattern (not shown), the edge finish 37, etc. are the same as those of the key holder 10 of the above-described embodiment, and the descriptions thereof apply as appropriate.

[0051] Furthermore, before the edge finishing process is performed on the end faces of the pass case 30, the surface of the surface member 32 having perforations on the outer periphery can be covered by gluing a window frame member (not shown) that will serve as a window frame for a hard display board made of transparent acrylic resin or the like with a printed pattern, thereby hiding the perforations and improving the appearance.

[0052] The manufacturing method of the pass case as a product of the present invention can also be carried out in the same manner as the manufacturing method of the key holder 10 described above, by folding it in half using an integrated fabric consisting of the front member 32, the back member 33, and the connecting parts that connect them.

[0053] Although the key holder and pass case (commuter pass holder) according to the above-described embodiment have been described as products of the present invention, the present invention is not limited to these products and can be modified to other products. [Industrial Applicability]

[0054] The present invention has industrial applicability as a key holder or pass case equipped with a hard display plate with a pattern, which has a smooth surface, excellent positional stability of the hard display plate, and can be produced easily and inexpensively. [Explanation of symbols]
