[0018] The key cover according to an embodiment of the present invention will be described below with reference to Figures 1 to 19. The embodiments described below are merely examples of the present invention, and the present invention is not limited to these embodiments. In these figures, the symbol X indicates the key cover according to this embodiment.

[0019] <Embodiment 1> The configuration and usage method of the key cover X according to Embodiment 1 will be described below with reference to Figures 1 to 4.

[0020] <<Structure>> The configuration of the key cover X will be explained below using Figures 1 and 2.

[0021] As shown in Figure 1, the key cover X in this embodiment is an article used for a key K having a key body k1 inserted into a keyhole and a gripping portion k2. In Figure 1, the dashed lines represent the inner layer 11a and the magnetic attachment portion 2, which will be described later.

[0022] As shown in Figure 2, the key cover X in this embodiment includes a cover portion 1 that is detachably attached to the grip portion k2, a magnetic attachment portion 2 provided on the cover portion 1, and a suspension portion 3 provided on the cover portion 1 that suspends the key K together with the cover portion 1. In Figure 2, the dashed line represents one of the pair of inner layers 11a and magnetic attachment portion 2, which will be described later. Furthermore, in Figure 2, the dotted line virtually represents the boundary between the outer layer 11b and the connecting portion 12, which will be described later.

[0023] The cover portion 1 has a pair of stacked portions 11 of substantially flat plates that are stacked and attached to the sides of the gripping portion k2, a connecting portion 12 that connects each stacked portion 11 so that it can be unfolded and folded, and a locking hole portion h1 that is provided so that the tongue portion 31, which will be described later, can be inserted and locked into it.

[0024] Each pair of laminated sections 11 includes an inner layer 11a laminated onto the gripping section k2, and an outer layer 11b laminated onto the inner layer 11a. Furthermore, it is preferable that the pair of laminated sections 11 each have approximately the same thickness. This ensures that the effect of the magnetic force of the magnetic attachment section 2, which will be described later, is uniform. Furthermore, the ends of the pair of laminated sections 11 may be joined by sewing them together. This protects the end face of the gripping section k2.

[0025] Each inner layer 11a has a fitting hole h2 formed in it. Each inner layer 11a has substantially the same shape and size as each outer layer 11b. Furthermore, each inner layer 11a is attached to each outer layer 11b by adhesive. In addition to adhesive bonding, various joining methods such as sewing can be applied to attach the inner layer 11a to the outer layer 11b.

[0026] Each fitting hole h2 has substantially the same shape as the magnetic attachment part 2, which will be described later. As will be described later, corresponding to the fact that a pair of magnetic attachment parts 2 are provided, each fitting hole h2 is composed of a pair of holes. In other words, a total of four holes are formed in the laminated part 11. Furthermore, each hole has a predetermined thickness and is formed in a substantially flat shape.

[0027] The connecting portion 12 is provided with an insertion hole h3 formed to allow the key body k1 to be inserted. The connecting portion 12 is the end face of the gripping portion k2 and covers the side that comes into contact with the key body k1. Furthermore, the connecting portion 12 connects the pair of outer layer portions 11b together. Furthermore, the outer layer 11b and the connecting portion 12 are integrally formed. Furthermore, the connecting portion 12 has a predetermined degree of flexibility, which enables the unfolding and folding of the stacked portion 11.

[0028] The insertion hole h3 is formed in an elongated shape along the width direction of the cover portion 1.

[0029] The locking hole h1 is provided at the end of one of the outer layers. Furthermore, the locking hole h1 detachably holds the tongue portion 31, which will be described later. Furthermore, the locking hole h1 is formed in an elongated shape along the width direction of the cover portion 1. Its length is approximately the same as the width of the tongue portion 31, which will be described later.

[0030] Each magnetic attachment portion 2 is formed in a substantially flat plate shape and is provided in pairs. In other words, the magnetic attachment portion 2 is a collective term for the magnetic attachment portions 2a and 2b, which are provided independently. The pair of magnetic attachment parts 2a and 2b are arranged on one side of the stacked part 11 at a predetermined distance from each other, along a direction substantially perpendicular to the direction in which the key body k1 extends. The pair of magnetic attachment parts 2a and 2b are fitted into the fitting holes h2 and bonded to the outer layer 11b. The magnetic attachment portion 2 is provided on each of the pair of stacked portions 11. That is, there are two magnetic attachment portions 2a and two magnetic attachment portions 2b on each of the key cover X.

[0031] The pair of magnetic attachment points 2a and 2b each have a north pole and a south pole positioned on their respective side surfaces. Furthermore, the magnetic attachment portions 2a facing each other across the gripping portion k2 are arranged such that the north pole belonging to one portion is adjacent to the gripping portion k2, and the south pole belonging to the other portion is adjacent to the gripping portion k2. Furthermore, the magnetic attachment portions 2a and 2b provided on the same stacked portion 11 are arranged such that the north pole of one magnetic attachment portion is adjacent to the gripping portion k2, and the south pole of the other magnetic attachment portion is adjacent to the gripping portion k2.

[0032] The suspension portion 3 has a tongue-shaped portion 31 that protrudes from the cover portion 1 and is configured to communicate with a suspension hole k3 provided in the gripping portion k2, and a hole portion 32 formed on the tip side of the tongue-shaped portion 31.

[0033] The tongue portion 31 is rounded at the tip. That is, the tip is formed in a roughly semi-circular shape when viewed from above.

[0034] In a plan view, the hole 32 is formed in a concentric circular shape with respect to the approximately semicircular shape formed in the tongue portion 31.

[0035] <<How to use>> The method of using the key cover X according to Embodiment 1 will be described below with reference to Figures 1, 3, and 4.

[0036] First, the user unfolds the laminated section 11, as shown in Figure 3. Next, the user inserts the key body k1 into the insertion hole h3, as shown in Figure 1. Finally, the user folds the stacked portion 11 and inserts the tongue portion 31 into the locking hole portion h1, thereby bringing the key cover X to the state shown in Figure 4. In Figure 3, the dashed line represents one of the pair of inner layers 11a and magnetic attachment portion 2. Furthermore, in Figure 3, the dashed line virtually represents the fold at the connecting portion 12. Furthermore, in Figure 4, the dashed lines represent the gripping portion k2, the inner layer portion 11a, and the magnetic attachment portion 2.

[0037] <<Effect>> According to this embodiment, the cover portion 1 and the magnetic attachment portion 2 can attract two keys K to each other, or a key K to another magnetic attachment body, by magnetic force.

[0038] Furthermore, since a fitting hole h2 into which the magnetic attachment part 2 is fitted is formed in the inner layer 11a, friction between the magnetic attachment part 2 and the gripping part k2 can be reduced when the key K is held in the key cover X.

[0039] Furthermore, the fact that the laminated portion 11 includes an inner layer portion 11a and an outer layer portion 11b improves ease of manufacturing.

[0040] Furthermore, the magnetic attachment parts 2 provided on each stacked section 11 exert an attractive force on them, thereby creating a key cover X that can maintain its folded state.

[0041] Furthermore, as shown in Figure 5, the arrangement of the pair of magnetic attachment parts 2 produces the effects detailed below. In Figure 5, the symbols S and N represent the polarity located on the sides of the magnetic attachment parts 2a and 2b that are adhered to the outer layer 11b. Furthermore, in Figure 5, the dotted lines represent typical magnetic forces acting between magnetically attached parts, without distinguishing between attractive and repulsive forces.

[0042] As shown in Figure 5(a), the opposing pair of key covers X are positioned so that their opposite polarities face each other, and therefore attract each other by magnetic force. Figure 5(b) shows the state in which one of the key covers X has been rotated around its height as the axis of rotation, from the state shown in Figure 5(a). In this case, the pair of opposing key covers X are positioned so that opposite polarities face each other, and therefore attract each other by magnetic force. Figure 5(c) shows the state in which one of the key covers X is rotated around a pivot point approximately perpendicular to its stacked portion 11, from the state shown in Figure 5(b). In this case, the opposing pair of key covers X are arranged so that those with the same polarity face each other, and therefore repel each other by magnetic force. In summary, by aligning the direction in which the suspension portion 3 extends and facing each other, the pair of key covers X according to this embodiment can be configured so that any of the stacked portions 11 belonging to one key cover X can be attached to each stacked portion 11 belonging to the other key cover X.

[0043] Furthermore, the hanging part 3 allows the key cover X to be attached to any key ring.

[0044] Furthermore, the tongue portion 31 and the locking hole portion h1 can protect the end face of the gripping portion k2.

[0045] Furthermore, the connecting portion 12 allows for the configuration of a key cover X that enables the user to easily grip the gripping portion k2 with the cover portion 1.

[0046] Furthermore, the insertion hole h3 allows the key body k1 to be inserted, enabling the construction of a key cover X with high retention capacity.

[0047] <Embodiment 2> The configuration and usage method of the key cover X according to Embodiment 2 will be described below with reference to Figures 6 to 8.

[0048] <<Structure>> The configuration of the key cover X according to Embodiment 2 will be described below with reference to Figures 6 to 8. In this embodiment, components that are essentially the same as those in Embodiment 1 are denoted by the same reference numerals, and their descriptions are simplified.

[0049] As shown in Figure 6, the key cover X in this embodiment is an article used for a key K having a key body k1 inserted into a keyhole, a gripping part k2, and a suspension hole k3.

[0050] The cover portion 1 has an auxiliary portion 12 connected to the end edge of the laminated portion 11. Here, the auxiliary part 12 has a configuration corresponding to the connecting part 12 in Embodiment 1.

[0051] As shown in Figure 7, the cover portion 1 is provided with a notch s along the longitudinal direction of the tongue portion 31 in the portion that connects to the tongue portion 31.

[0052] The laminated portion 11 is a substantially flat plate-like body that is laminated and attached to only one side of the gripping portion k2.

[0053] As shown in Figure 8, the auxiliary part 12 has an insertion hole h3 through which the key body k1 can be inserted.

[0054] <<How to use>> The method of using the key cover X according to Embodiment 2 will be explained below with reference to Figures 6 to 8. First, the user inserts the key body k1 into the insertion hole h3, as shown in Figure 8. Subsequently, the user inserts the tongue portion 31 into the suspension hole k3, as shown in Figure 7. This brings the key cover X to the state shown in Figure 6.

[0055] <<Effect>> According to this embodiment, the laminated portion 11 is laminated and attached to only one side of the gripping portion k2, making it possible to construct a thinner key cover X compared to Embodiment 1. Therefore, when multiple key covers X are laminated together, the bulk is reduced.

[0056] Furthermore, the notch s prevents the end face of the gripping portion k2 from protruding from the end face of the laminated portion 11 when the tongue portion 31 is inserted through the suspension hole k3.

[0057] Furthermore, the through-hole h3 and the tongue portion 31 allow for the construction of a key cover X capable of holding the key K.

[0058] <Embodiment 3> The configuration and manufacturing method of the key cover X according to Embodiment 3 will be described below with reference to Figures 9 and 10.

[0059] <<Structure>> The configuration of the key cover X according to Embodiment 3 will be described below with reference to Figure 9. In this embodiment, components that are essentially the same as those in Embodiment 1 or Embodiment 2 are denoted by the same reference numerals, and their descriptions are simplified.

[0060] As shown in Figure 9, the key cover X according to this embodiment covers the side and end faces of the gripping portion k2. In Figure 9, the thick dotted lines represent sewing threads.

[0061] The pair of laminated sections 11 are sewn together at their edges.

[0062] The connecting portion 12 is adjacent to the end face of the gripping portion k2 on the side that is spaced apart from the key body k1.

[0063] The pair of magnetic attachment parts 2 are arranged such that one N pole is adjacent to the gripping part k2 and the other S pole is adjacent to the gripping part k2. Furthermore, each magnetic attachment portion 2 may be provided in pairs. This allows for the same effects as in Embodiments 1 and 2 to be achieved.

[0064] The suspension portion 3 is a hole that communicates with the suspension hole k3 provided in the gripping portion k2.

[0065] <<Manufacturing method>> The manufacturer provides a suspension part 3 that corresponds to the shape and size of the suspension hole k3 provided in each key K. That is, as shown in Figure 10, the manufacturer provides holes of the same shape and size at corresponding positions in the inner layer 11a and the outer layer 11b, respectively.

[0066] <<Effect>> According to this embodiment, a key cover X capable of protecting the end face of the gripping portion k2 can be constructed by sewing the laminated portion 11 together.

[0067] Furthermore, the presence of only one magnetic attachment section 2 ensures that space is available for the suspension section 3.

[0068] Furthermore, since the suspension portion 3 is a hole, it is possible to manufacture a simpler key cover X compared to Embodiments 1 and 2.

[0069] <Embodiment 4> The key cover X according to Embodiment 4 will be described below with reference to Figures 11 and 12.

[0070] <<Structure>> The configuration of the key cover X according to Embodiment 4 will be described below with reference to Figure 11. In this embodiment, components that are essentially the same as those in any of Embodiments 1 to 3 are denoted by the same reference numerals, and their descriptions are simplified.

[0071] As shown in Figure 11, the suspension portion 3 is a hole that communicates with the suspension hole k3 provided in the gripping portion k2, and the connecting portion 12 is provided with an insertion hole h3, as shown in Figure 12.

[0072] <<Effect>> According to this embodiment, the insertion hole h3 and the suspension portion 3 which is a hole allow for the construction of a key cover X that is simpler than those of Embodiments 1 and 2, while still ensuring the ability to hold the key K.

[0073] <Embodiment 5> The key cover X according to Embodiment 5 will be described below with reference to Figure 13.

[0074] <<Structure>> The configuration of the key cover X according to Embodiment 5 will be described below with reference to Figure 13. In this embodiment, components that are basically the same as those in any of Embodiments 1 to 4 are denoted by the same reference numerals, and their descriptions are simplified.

[0075] As shown in Figure 13, in the key cover X according to this embodiment, one laminated portion 11 is provided with protrusions a near its four corners in a plan view, and the other laminated portion 11 is provided with recesses b near its four corners in a plan view. Each laminated section 11 is attached to one another by the fitting of its convex portion a and concave portion b. In Figure 13, the dashed lines represent one side of the fitting hole h2, one side of the groove h4 (described later), and the protrusion a.

[0076] Each laminated section 11 is provided with a groove h4 on its side surface. The sum of the depths of the pair of grooves h4 formed should be greater than the thickness of the gripping section k2. Therefore, it is possible that only one of the laminated sections 11 is provided with a groove h4 having a depth greater than the thickness of the gripping section k2.

[0077] One of the laminated sections 11 has a notch n at its end. The depth of the notch n should be large compared to the thickness of the key body k1. Therefore, each of the pair of laminated sections 11 may have a notch n.

[0078] Each laminated section 11 is formed integrally from a single material. Furthermore, it is preferable that each laminated section 11 be made of a material that is easy to process, such as plastic, and has a predetermined rigidity.

[0079] The suspension portion 3 is an elongated hole provided at the end of the cover portion 1. The suspension part 3 may or may not be in communication with the suspension hole k3.

[0080] <<Effect>> According to this embodiment, the convex portion a and the concave portion b make it possible to form a pair of laminated portions 11 that are difficult to detach from one another.

[0081] Furthermore, the notch n prevents interference between the laminated portion 11 and the key body k1, thereby ensuring the functionality of the convex portion a and concave portion b described above.

[0082] Furthermore, the grooves h4 do not prevent the construction of the laminated portion 11 from a rigid member, and allow for the construction of a laminated portion 11 that is held in close contact with the gripping portion k2.

[0083] Furthermore, because the suspension portion 3 is a long, elongated hole, space is secured for the groove portion h4 to be provided.

[0084] <Example of changes> The shapes and dimensions of the components shown in the above embodiment are merely examples and can be modified in various ways based on design requirements, etc.

[0085] For example, the inner layer 11a may not be provided. In this case, the magnetic attachment portion 2 is not fitted into the fitting hole h2, but is held to the laminated portion 11 solely by a holding means such as adhesive.

[0086] Furthermore, the inner layer 11a and the outer layer 11b may be composed of a single member and integrally formed. In this case, the fitting hole h2 is provided in the laminated portion 11 and is configured as a groove having a bottom.

[0087] Furthermore, as shown in Figures 14 and 15, the fitting hole h2 may be provided in the outer layer portion 11b. In this case, it is preferable to provide only one magnetic attachment portion 2. This allows for a larger surface area on the side of the magnetic attachment portion 2, thereby increasing the contact area with the cover portion 1. Consequently, even though the magnetic attachment portion 2 is exposed, the mounting can be made relatively secure.

[0088] Furthermore, as shown in Figures 16 and 17, the suspension portion 3 may be a hole, and the fitting hole h2 may be provided in the outer layer portion 11b.

[0089] Furthermore, as shown in Figures 18 and 19, the insertion hole h3 may be provided in the connecting portion 12, and the fitting hole h2 may be provided in the outer layer portion 11b.

[0090] Furthermore, the magnetic attachment portion 2 may be provided on only one of the pair of stacked portions 11.

[0091] In application documents, the term "abbreviated" is a concept that includes shapes that have been chamfered or rounded, or shapes whose constituent elements have been modified or altered in length to the extent that it does not impede the purpose of the shape. [Explanation of Symbols]
