Description

Can badge keychain

[0001] The present invention relates to a can badge key holder in which a can badge and a key holder main body are connected.

[0002] Key chains are originally used to carry keys together, but in recent years they have come to play a more important role as accessories. In particular, can badge key chains, which combine a can badge with a key chain itself, are popular as accessories to attach to bags, etc. One such can badge key chain is shown in Non-Patent Document 1.

[0003] As shown in Figures 11 and 12, this can badge key holder comprises a key holder body 90 and a can badge 92 connected by a jump ring 91. Here, Figure 11 is a view of the can badge 92 from the front side, and Figure 12 is a view of the can badge 92 from the back side. Also, Figure 13 is an exploded view of the can badge 92 from the back side. As shown in Figure 13, the key holder body 90 comprises a double-ringed metal key ring 90a with a notch for a key, a chain 90b connecting approximately ring-shaped components together like a string, and a ring-shaped jump ring 90c that serves to connect the components. Furthermore, the can badge 92 comprises a disc-shaped front plate 93 with a decorative surface, a disc-shaped metal back plate 94, and a resin connecting member 95 attached to the back plate 94.

[0004] The back plate 94 has a fitting hole 94a into which a connecting member 95 fits. The connecting member 95 comprises a generally disk-shaped connecting member body 95a and a tongue 95b protruding from the outer periphery of the connecting member body 95a. A step 95c is formed along the outer periphery between the front side (the rear side in FIG. 13 ) and the back side (the front side in FIG. 13 ) of the connecting member body 95a, and four fitting claws 95d are provided, dividing the outer periphery of the front side (the rear side in FIG. 13 ) of the connecting member body 95a into four equal parts. The tongue 95b also has a connecting hole 95e through which a jump ring 91 passes to connect the chain 90b and the connecting member 95. 14, when the front side (right side in FIG. 14) of the connecting member main body 95a is pressed into the fitting hole 94a from the back side (left side in FIG. 14) of the back plate 94, the back plate 94 is held in a state where it is inserted into the step portion 95c by the fitting claws 95d, and the connecting member 95 is attached to the back plate 94. Here, FIG. 14 is a cross-sectional view taken along the line XIV-XIV in FIG. 12.

[0005] This can badge key holder is manufactured by crimping the outer peripheries of the front plate 93 and back plate 94 together, then forcing the connecting member body 95a into the fitting hole 94a to assemble the can badge 92. The can badge 92 and key holder body 90 are then connected with a jump ring 91 using a tool to manufacture the can badge key holder. With this can badge key holder, the connecting member 95 can be easily attached to the back plate 94 by forcing the connecting member body 95a into the fitting hole 94a of the back plate 94.

[0007] However, in the can badge key holder described in Non-Patent Document 1, like a typical can badge key holder, the can badge 92 and the key holder body 90 are connected to each other using a jump ring 91 with a tool. This process requires a tool and is tedious. Therefore, if it were possible to easily connect the can badge and the key holder body without using a tool, it would be possible to shorten the cycle time and reduce manufacturing costs. To solve this problem, the inventors conducted extensive research and came up with the present invention.

[0008] The present invention has been made in view of the above-mentioned conventional problems, and aims to provide a can badge key holder that can shorten the cycle time and reduce the manufacturing cost.

[0009] In order to solve the above problem, the feature of the can badge key holder of claim 1 is that in the can badge key holder which connects a can badge and a key holder body, the can badge consists of a front plate body, a resin back plate body which is crimped to the front plate body at the outer periphery, and a resin connecting member attached to the back plate body, the back plate body has an engaging hole, and the connecting member has an engaging protrusion which engages and locks into the engaging hole, and a connecting hole to which the key holder body is connected, and the can badge and key holder body are connected by manually inserting one end of the key holder body into the connecting hole without using tools, and then engaging and locking the engaging protrusion into the engaging hole.

[0010] The feature of the can badge key holder of claim 2 is that, in claim 1, the connecting member consists of two elongated, plate-shaped main plates arranged approximately parallel with a certain gap between them, and a circular ring portion formed continuously from the base ends of the two main plates, and the connecting hole opening into the gap between the two main plates is provided in the circular ring portion.

[0011] The feature of the can badge key holder of claim 3 is that, in claim 2, the back plate has two parallel rectangular fitting holes extending radially of the back plate at a predetermined interval, and the fitting protrusions are each erected on the back surface of the tip side of the two main plates of the connecting member, and the fitting protrusions consist of two locking pieces extending parallel to the longitudinal direction of the main plate and locking claws provided at the upper ends of the locking pieces and protruding outward, and the contour shape formed by the two locking pieces is such that the cross-sectional shape parallel to the main plate is approximately the same shape as the fitting holes.

[0012] The can badge key holder according to claim 1 has a back plate provided with a fitting hole, and a connecting member provided with a fitting protrusion that fits into the fitting hole and a connecting hole to which the key holder body is connected. The can badge and key holder body are connected by manually inserting one end of the key holder body into the connecting hole and then fitting the fitting protrusion into the fitting hole without using tools. This eliminates the need for a jump ring to connect the can badge and key holder body, reducing the number of parts. Furthermore, the can badge and key holder body can be easily connected without using tools. This can badge key holder therefore reduces cycle time and manufacturing costs. Furthermore, because the back plate and connecting member are made of resin, they can be manufactured inexpensively, further reducing manufacturing costs.

[0013] In the can badge key holder according to claim 2, the connecting member comprises two elongated, plate-like main plates arranged substantially parallel to each other with a certain gap between them, and a circular ring portion formed continuously from the base ends of the two main plates. The ring portion has a connecting hole that opens into the gap between the two main plates. Therefore, by inserting one of the main plates through a ring portion, such as a jump ring, at one end of the key holder body and moving the one end of the key holder body to the connecting hole, the connecting member and the key holder body can be easily connected without using tools.

[0014] The can badge key holder of claim 3 has two parallel rectangular mating holes extending radially at a predetermined distance from the back plate. Furthermore, a mating protrusion is provided on the rear surface of each of the two main plates of the connecting member at the distal end. Each mating protrusion consists of two locking pieces extending parallel to the longitudinal direction of the main plate and a locking claw located at the upper end of each locking piece and protruding outward. Furthermore, the contour shape formed by the two locking pieces, and the cross-sectional shape parallel to the main plate, is approximately the same as that of the mating holes, so the mating protrusions and mating holes are securely mated and locked. Therefore, the connecting member does not rotate or rattle. The length of the predetermined "distance" between the two mating holes is approximately the same as the length of the "gap" between the two main plates of the connecting member.

[0016] An embodiment of a can badge key holder according to the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, this can badge key holder comprises a key holder main body 80 and a can badge 1 connected by a connecting member 30 included in the can badge 1. Here, FIG. 1 is a view of the can badge 1 from the front side, and FIG. 2 is a view of the can badge 1 from the back side. Also, FIG. 3 is an exploded view of the can badge 1 from the back side. As shown in FIG. 3, the key holder main body 80 comprises a double-ringed metal key ring 80a with a notch for inserting a key, a rotating ring 80b in which the two rings rotate independently to prevent twisting, and annular jump rings 80c and 80d for connecting components. This key holder main body 80 is a conventional, existing type. However, the key holder main body 80 is not necessarily limited to this configuration. For example, a so-called snap hook may be used instead of the key ring 80a, and a chain may be used instead of the rotating ring 80b. The can badge 1 is made up of a disc-shaped front plate 10 with a decorative surface, a disc-shaped resin back plate 20, and a resin connecting member 30 attached to the back plate 20. The front plate 10 is a typical disc-shaped metal substrate on which a decorated decorative sheet and a transparent resin film are laminated and pressed.

[0017] As shown in Figures 4 and 5, the back plate 20 is made of resin and has a disk shape. This allows for easier and more cost-effective manufacturing than metal back plate 20. Figures 4(1) and 4(2) are front and rear views, respectively. When the back plate 20 and the face plate 10 are crimped together at their outer peripheries to form the can badge 1, the front surface 21 shown in Figure 4(1) can be seen from the back side of the can badge 1, while the back surface 22 shown in Figure 4(2) is inside the can badge 1 and cannot be seen. The front surface 21 side of the back plate 20 consists of an outer peripheral portion 21a and a curved portion 21b. The outer peripheral portion 21a is formed in a roughly annular shape on the outer periphery of the front surface 21 side, and the surface of the outer peripheral portion 21a is flat. The curved portion 21b is formed inside the outer peripheral portion 21a, and the surface of the curved portion 21b is a curved surface that curves gently convexly toward the center. The back surface 22 side of the back plate 20 consists of an outer peripheral portion 22a and a recessed portion 22b. The outer peripheral portion 22a is formed in a substantially circular ring shape on the outer periphery of the back surface 22, and the surface of the outer peripheral portion 22a is flat. The recessed portion 22b is formed in a concave shape on the inside of the outer peripheral portion 22a, and the surface of the recessed portion 22b is flat. Note that the outer peripheral portion of the recessed portion 22b and the portion near the fitting hole 23 may be left as they are, and the surface of the other portion may be made thin and curved like the curved portion 21b. This can reduce material costs and the weight of the product.

[0018] Two parallel rectangular fitting holes 23 are provided at a predetermined distance d1, extending from near the boundary between the outer peripheral portion 21a and the curved portion 21b toward the center. The length of the distance d1 is the same as the length of the gap d2 (see FIGS. 6 and 7) between the fitting protrusions 33 (described later). The fitting holes 23 engage with the fitting protrusions 33 (see FIGS. 6 and 7), connecting the can badge 1 and the key holder body 80. Two radially parallel side surfaces of the fitting holes 23 are locking surfaces 23a, and locking pieces 33a (see FIGS. 6 and 7) of the fitting protrusions 33 (described later) engage with the locking surfaces 23a. A step 21c is formed on the side surface 21, perpendicular to the radial direction and toward the center. The surface of the step 21c is flat and is flush with the surface of the outer peripheral portion 21a. Furthermore, the surfaces of the outer periphery 21a and the step 21c are parallel to the surface of the recess 22b.

[0019] As shown in Figures 6 and 7, the connecting member 30 comprises two elongated, plate-like main body plates 31 arranged substantially parallel to each other with a gap d2 between them, and an annular portion 32 formed continuously from the base ends 31b of the two main body plates 31. Figures 6(1) and 6(2) are front and side views, respectively, and Figures 7(1) and 7(2) are plan and rear views, respectively. The annular portion 32 has a connecting hole 32a that opens into the gap d2 between the two main body plates 31. Therefore, by passing the tip 31a of one of the main body plates 31 through one end of the key holder body 80, the connecting member 30 and the key holder body 80 can be easily connected without using tools.

[0020] Furthermore, a fitting protrusion 33 is erected on the back surface 31c of each of the two main body plates 31 of the connecting member 30 on the tip end 31a side. The fitting protrusion 33 is composed of two locking pieces 33a extending parallel to the longitudinal direction of the main body plate 31 and a locking claw 33b provided at the upper end of the locking piece 33a and protruding outward. The cross section is parallel to the back surface 31c of the main body plate 31, and the rectangular outline L formed by the two locking pieces 33a is substantially the same shape as the fitting hole 23. Therefore, the fitting protrusion 33 and the fitting hole 23 are firmly fitted and locked together.

[0021] The method for assembling the can badge key holder configured as described above will now be described. First, the front plate 10 and back plate 20, which are made by laminating and crimping a decorative sheet and a transparent resin film on a disc-shaped metal substrate, are crimped together at their outer edges to assemble the can badge 1, which does not yet have a connecting member 30 attached. Next, as shown in FIG. 8 , the tip 31a of one of the main plates 31 is inserted into the ring portion of the jump ring 80d at one end of the key holder body 80. Then, the key holder body 80 is moved as shown by arrow A until the jump ring 80d enters the connecting hole 32a. This allows the connecting member 30 and the key holder body 80 to be easily connected without the use of tools.

[0022] 9 and 10, the fitting protrusion 33 of the connecting member 30 is fitted into the fitting hole 23 of the back plate 20. The relationship between the fitting protrusion 33 and the fitting hole 23 at this time will be described in detail. First, when the fitting protrusion 33 of the connecting member 30 is brought close to and fitted into the fitting hole 23 of the back plate 20, the two locking claws 33b are pushed inward by the locking surfaces 23a on both sides of the fitting hole 23. This causes the locking pieces 33a to bend, and the two locking claws 33b move in directions approaching each other.

[0023] Furthermore, when the fitting protrusion 33 is fitted into the fitting hole 23, the back surface 31c of the connecting member 30 abuts against the outer periphery 21a and the surface of the step 21c of the back plate 20, and the locking claw 33b escapes from the fitting hole 23. This removes the force that the locking claw 33b receives from the locking surface 23a, and the locking pieces 33a move away from each other due to elastic force and return to their original positions. Here, because the rectangular outline L formed by the two locking pieces 33a is substantially the same shape as the fitting hole 23, the locking pieces 33a and the locking surface 23a come into close contact with each other, firmly engaging and locking the fitting protrusion 33 and the fitting hole 23. Furthermore, because the locking claw 33b extends outward from the fitting hole 23, the fitting protrusion 33 does not escape from the fitting hole 23. This prevents the connecting member 30 from rotating or rattling. In this way, the can badge 1 and the key holder body 80 are connected to assemble the can badge key holder shown in Figures 1 and 2. The surface of the outer periphery 21a of the back plate 20 and the surface of the step 21c are not only on the same plane, but are also parallel to the surface of the recess 22b, which effectively prevents rattling between the connecting member 30 and the back plate 20.

[0024] In the can badge key holder of this embodiment, a fitting hole 23 is provided in the back plate 20, and a fitting protrusion 33 that fits into and engages with the fitting hole 23 is provided in the connecting member 30, along with a connecting hole 32a to which the key holder body 80 is connected. Then, by manually inserting a jump ring 80d at one end of the key holder body 80 into the connecting hole 32a without using tools, the fitting protrusion 33 is engaged with the fitting hole 23, thereby connecting the can badge 1 and the key holder body 80. This eliminates the need for a separate jump ring to connect the can badge 1 and the key holder body 80, thereby reducing the number of parts. Furthermore, the can badge 1 and the key holder body 80 can be easily connected without using tools. Therefore, this can badge key holder shortens cycle time and reduces manufacturing costs. Furthermore, because the back plate 20 and connecting member 30 are made of resin, they can be manufactured inexpensively, further reducing manufacturing costs.

[0025] In addition, in this can badge key holder, the connecting member 30 is composed of two elongated, plate-like main body plates 31 arranged approximately parallel to each other with a certain gap d2 between them, and an annular portion 32 formed continuously from the base ends 31b of the two main body plates 31. The annular portion 32 is provided with a connecting hole 32a that opens into the gap d2. Therefore, by inserting the tip 31a of one of the main body plates 31 into the ring portion of the jump ring 80d at one end of the key holder body 80 and moving the jump ring 80d at one end of the key holder body 80 to the connecting hole 32a, the connecting member 30 and the key holder body 80 can be easily connected without using tools.

[0026] Furthermore, in this can badge key holder, the back plate 20 is provided with two parallel, rectangular mating holes 23 extending radially and spaced a predetermined distance d1 apart. A mating protrusion 33 is provided on the back surface 31c of each of the two main plates 31 of the connecting member 30, near the tip 31a. Each mating protrusion 33 consists of two locking pieces 33a extending parallel to the longitudinal direction of the main plate 31 and a locking claw 33b located at the upper end of each locking piece 33a and protruding outward. The outline L formed by the two locking pieces 33a has a cross-sectional shape parallel to the main plate 31 that is substantially the same as that of the mating hole 23, ensuring a secure mating engagement between the mating protrusions 33 and the mating hole 23. This prevents the connecting member 30 from rotating or rattling.

[0027] The above describes the can badge key holder of the present invention based on an embodiment, but it goes without saying that the present invention is not limited to these and can be modified and applied as appropriate as long as it does not contradict the technical concept of the present invention.
