DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] <First embodiment> Hereinafter, a key holder 10 according to a first embodiment will be described with reference to Figs. 1 to 10. The key holder 10 can be used as a tool for bundling keys, and can also be used as a pendant to be attached to a bag, a mobile phone, or the like. Fig. 1 is a perspective view of the key holder 10. As shown in Fig. 1, the key holder 10 includes a case body 3 composed of a window member 1 and a frame member 2, a lid 4 rotatably attached to the case body 3, four decorative plates 5 stored inside the case body 3, and a ball chain 6. Fig. 2 is a perspective view showing a state in which the ball chain 6 is removed from the key holder 10 and the lid 4 is opened. The lid 4 can be rotated from the closed state shown in Fig. 1 to the open state shown in Fig. 2. The decorative plates 5 stored inside the case body 3 can be replaced by opening the lid 4 as shown in Fig. 2.

[0016] FIG. 3 is a perspective view of the window member 1. FIG. 4 is a rear view of the window member 1. The window member 1 is a member made of transparent resin and has a substantially flat plate shape. The window member 1 does not need to be completely transparent over the entire surface, and a pattern or the like may be drawn on a part of the window member 1 as long as the decorative plate 5 stored in the case body 3 can be seen through the window member 1. As shown in FIGS. 3 and 4, the window member 1 has a central portion 11 and an edge portion 12 having a plate thickness thinner than that of the central portion 11. The edge portion 12 is continuous in a U-shape with the right end portion, the lower end portion, and the left end portion of the window member 1 in FIG. 4. The central portion 11 has one recess 13 formed at each of the upper right portion and the upper left portion in FIG. 4. The plate thickness of the portion where the recess 13 is formed is the same as that of the edge portion 12. In addition, the central portion 11 has a cylindrical recess 14 formed at the upper left end portion in FIG. 4. Furthermore, the window member 1 has a protrusion 15 protruding upward in FIG. 4. The tip of the protruding portion 15 has a semicircular shape when viewed from the front. A circular first through hole 16 is provided at the center of the semicircle in the protruding portion 15. The plate thickness of the protruding portion 15 is the same as that of the central portion 11.

[0017] FIG. 5 is a perspective view of the frame member 2. FIG. 6 is a front view of the frame member 2. As shown in FIGS. 5 to 6, the resin frame member 2 includes a flat plate portion 21 and a side wall portion 22. The side wall portion 22 is continuous with the right end, the lower end, and the left end of the frame member 2 in FIG. 6 in a U-shape. The side wall portion 22 includes an outer portion 221 and an inner portion 222 that is lower in the plate thickness direction of the flat plate portion 21 than the outer portion 221. The outer portion 221 and the inner portion 222 are both continuous with the right, lower, and left ends in a U-shape in FIG. The outer portion 221 is provided with convex portions 23 that protrude inward at the upper right and upper left sides in FIG. 6. In addition, the flat plate portion 21 is formed with a cylindrical recess 24 at the upper right end in FIG. 6. Furthermore, the frame member 2 includes a protruding portion 25 that protrudes upward in FIG. 6. The tip of the protruding portion 25 is semicircular when viewed from the front. A circular second through hole 26 is provided in the protruding portion 25 at the center of the semicircle. The plate thickness of the protruding portion 25 is the same as that of the flat plate portion 21. The frame member 2 may be transparent. When the frame member 2 is transparent, the decorative plate 5 stored in the case body 3 can be seen through the frame member 2.

[0018] FIG. 7 is a perspective view of the lid 4. FIG. 8 is a rear view of the lid 4. FIG. 9 is a top view of the lid 4. As shown in FIGS. 7 to 9, the resin lid 4 includes a lid body 41 having a substantially rectangular prism shape with both ends processed to be semicircular when viewed from the front, and a protruding portion 42 protruding from the center of the lid body 41. The tip of the protruding portion 42 has a semicircular shape when viewed from the front. The protruding portion 42 has a circular third through hole 43 at the center of the semicircle. The lid body 41 is provided with a rotating shaft 44 at one end and a protruding portion 45 at the other end. The rotating shaft 44 is a substantially cylindrical protrusion protruding to both sides from one end of the lid body 41 as shown in FIG. 9.

[0019] The case for storing the decorative plate 5 can be assembled by fitting the window member 1 to the frame member 2 with the rotation shaft 44 of the lid 4 inserted into the cylindrical recess 14 of the window member 1 and the cylindrical recess 24 of the frame member 2. The window member 1 is fitted to the frame member 2 by positioning the protrusion 23 of the frame member 2 so that it fits into the recess 13 of the window member 1, and then pushing the center portion 11 of the window member 1 into the outer portion 221 of the side wall portion 22 of the frame member 2. Then, by fitting the window member 1 to the frame member 2 with the rotation shaft 44 of the lid 4 inserted into the cylindrical recess 14 of the window member 1 and the cylindrical recess 24 of the frame member 2 in this manner, a case main body 3 in which the window member 1 is fixed to the frame member 2 is formed, and the lid 4 is attached to the case main body 3 so as to be rotatable. Because the key holder 10 secures the window member 1 to the frame member 2 by fitting in this manner, the window member 1 can be secured to the frame member 2 with less effort than if the window member 1 were secured to the frame member 2 using screws or the like.

[0020] When the window member 1 is fitted and fixed to the frame member 2, a storage space for storing the decorative plate 5 and an opening leading to the storage space are formed between the window member 1 and the frame member 2. In this state in which the window member 1 is fixed to the frame member 2, the first through hole 16 of the window member 1 and the second through hole 26 of the frame member 2 are aligned in a straight line as shown in FIG. 2. Then, when the lid 4 rotatably attached to the case body 3 is closed, the convex portion 45 of the lid 4 comes into contact with the inner portion 222 of the side wall portion 22 of the frame member 2, and the opening leading to the storage space can be blocked. When the lid 4 is closed in this manner, the first through hole 16 of the window member 1, the second through hole 26 of the frame member 2, and the third through hole 43 of the lid 4 are aligned in a straight line. By passing the ball chain 6 through the first through hole 16, the second through hole 26 and the third through hole 43 which are aligned in a straight line as shown in Figure 1, the lid 4 cannot rotate, and the lid 4 is kept blocking the opening leading to the storage space, preventing the stored decorative plate 5 from coming out of the case body 3.

[0021] As shown in FIG. 1, the ball chain 6 has a structure in which a plurality of metal balls 61 are linked together, and includes a connector 62 that can connect the balls 61 at both ends. The diameter of the ball 61 is set to a size that allows it to pass through the first through hole 16, the second through hole 26, and the third through hole 43. The ball chain 6 is in a state in which the balls 61 are linked together in a ring shape by connecting the balls 61 at both ends with the connector 62. The ball chain 6 can be changed to a state in which the balls 61 are linked together in a line by removing one of the balls 61 from the connector 62. Such a connector 62 can be attached and detached by hand without using tools or the like.

[0022] The key holder 10 can be used to bundle keys by passing the ball chain 6 through the first through hole 16, the second through hole 26, and the third through hole 43 with the lid 4 closed, bundling keys (not shown) with the ball chain 6, and then connecting the balls 61 at both ends with the connector 62. The key holder 10 can also be used as a hanging ornament for a bag, a mobile phone, or the like by passing the ball chain 6 through the first through hole 16, the second through hole 26, and the third through hole 43 with the lid 4 closed, attaching the ball chain 6 to a bag, a mobile phone, or the like (not shown), and then connecting the balls 61 at both ends with the connector 62. The ball chain 6 is an example of a metal fitting that is passed through the first through hole 16, the second through hole 26, and the third through hole 43. The key holder 10 can also use metal fittings with a shape different from the ball chain 6, such as a double ring, as the metal fitting that is passed through the first through hole 16, the second through hole 26, and the third through hole 43. However, by using the ball chain 6, the key holder 10 can be attached directly to the shoulder strap of a shoulder bag or the handle of a handbag, unlike when a double ring or the like is used.

[0023] FIG. 10 is a perspective view of a decorative plate 5 made of acrylic resin. As shown in FIG. 10, the decorative plate 5 has a substantially square flat plate shape with rounded corners. As shown in FIGS. 1 and 2, four decorative plates 5 can be stored in the storage space of the case body 3 at the same time. The shape and size of the decorative plate stored in the case body 3 may be different from that of the decorative plate 5 shown in FIG. 10, as long as it can be stored in the storage space of the case body 3 and pass through an opening leading to the storage space. For example, it may be possible to store only one decorative plate having a substantially square flat plate shape with an area equivalent to four decorative plates 5.

[0024] Although not shown in FIG. 10, the decorative plate 5 has an image of, for example, an animation or game character drawn on it. When the decorative plate 5 is stored in the case body 3, the decorative plate 5 can be seen through the transparent window member 1. Therefore, by attaching the key holder 10 to a bag or the like, the user can carry the key holder 10 with the character or the like visible when going out. Note that the decorative plate 5 may have an image of a real person or the like other than a character drawn on it, or may have a pattern or the like other than a character or a person drawn on it.

[0025] The decorative plate 5 stored in the key holder 10 can be replaced by removing the ball chain 6, opening the lid 4 and replacing the decorative plate 5, and then closing the lid 4 and passing the ball chain 6 through the first through hole 16, the second through hole 26 and the third through hole 43. In this way, the decorative plate 5 stored in the key holder 10 can be easily replaced without disassembling the case that stores the decorative plate 5.

[0026] <Second embodiment> Hereinafter, the key holder 20 of the second embodiment will be described with reference to FIG. 11. The key holder 20 can be used as a tool for bundling keys, similar to the key holder 10 of the first embodiment, and can also be used as a hanging ornament attached to a bag, a mobile phone, etc. FIG. 11 is a front view showing the state in which the lid 4a of the key holder 20 is opened and the decorative plate 5a is removed. As shown in FIG. 11, the key holder 20 includes a case body 3a composed of a window member 1a and a frame member 2a, a lid 4a rotatably attached to the case body 3a, two decorative plates 5a stored inside the case body 3a, and a ball chain (not shown).

[0027] The window member 1a is a member made of transparent resin and has a substantially flat plate shape having a substantially heart-shaped shape when viewed from the front. A first through hole 16a is formed in the window member 1a. The frame member 2a has a flat plate portion having a substantially heart-shaped shape similar to that of the window member 1a, and a side wall portion 22a provided on a part of the outer edge of the flat plate portion. In FIG. 11, the side wall portion 22a of the frame member 2a is depicted by a dashed line. A second through hole (not shown) is formed in the flat plate portion of the frame member 2a. The second through hole of the frame member 2a is formed at a position aligned on a straight line with the first through hole 16a of the window member 1a when the window member 1a is fixed to the frame member 2a. Since both the window member 1a and the frame member 2a have a substantially heart-shaped shape when viewed from the front, the case main body 3a also has a substantially heart-shaped shape when viewed from the front.

[0028] The window member 1a is fixed to the frame member 2a by fitting. By fitting and fixing the window member 1a to the frame member 2a, a storage space for storing the decorative plate 5a and an opening leading to the storage space are formed between the window member 1a and the frame member 2a. When the lid 4a is closed, the end of the lid 4a comes into contact with the side wall portion 22a of the frame member 2a, and the opening leading to the storage space can be blocked. When the lid 4a is closed in this manner, the first through hole 16a of the window member 1a, the second through hole of the frame member 2a, and the third through hole 43a of the lid 4a are aligned in a straight line. Then, by passing a ball chain through the first through hole 16a, the second through hole, and the third through hole 43a aligned in this manner, the lid 4a cannot rotate, and the lid 4a can be held in a state of blocking the opening leading to the storage space, so that the stored decorative plate 5a cannot go out of the case body 3a.

[0029] The two decorative plates 5a are both flat plates in the shape of a heart cut in half. The two decorative plates 5a can be stored simultaneously in the storage space of the case body 3a. The shape and size of the decorative plate stored in the case body 3a may be different from the shape and size of the decorative plate 5a shown in FIG. 11 as long as it can be stored in the storage space of the case body 3a and pass through an opening leading to the storage space. For example, it may be possible to store only one decorative plate in the shape of a heart-shaped flat plate made up of two decorative plates 5a.

[0030] Although not shown in FIG. 11, the decorative plate 5a has an image of, for example, an animation or game character drawn on it. When the decorative plate 5a is stored in the case body 3a, it can be seen through the transparent window member 1a. After removing the ball chain and opening the lid 4a to replace the decorative plate 5a, the key holder 20 can replace the stored decorative plate 5a by closing the lid 4a and passing the ball chain through the first through hole 16a of the window member 1a, the second through hole of the frame member 2a, and the third through hole 43a of the lid 4a. In this way, the key holder 20 can easily replace the stored decorative plate 5a without disassembling the case in which the decorative plate 5a is stored. [Explanation of symbols]
