Description

  The present invention relates to a key holder, and more particularly to a key holder that is not bulky when carrying a key and has high fashionability.

The original purpose of use of the key holder was to bundle a large number of keys in one hand, but the emphasis on decoration has gradually increased, and various shapes of key holders are now being produced.
As a key holder that focuses on its original role, for example, a key holder having a tri-fold cover made mainly of a flexible material such as leather is known. In this type of key holder, a metal fitting such as a hook is placed at a position corresponding to the central portion inside the cover when the cover is folded in three to hold the key, and snap buttons provided at both ends on the outside of the cover are fitted to store the key. It is common to carry in the state. It is also possible to provide decorativeness by coloring or crafting the outside of the cover.

  On the other hand, key holders sold especially for young people are mainly those in which a chain or the like is connected to a ring-shaped metal fitting that can be opened and closed, and a mascot or doll is attached to the end of the chain. This type of key holder is not limited to a tool for holding a key, but is often attached to a bag or the like and used as an ornament. Since it is cheaper than a tri-fold key holder, it is often manufactured and sold as a souvenir of a tourist destination, for example.

Some of the latter key holders not only have a decorative effect as a mascot but also have a practical or entertainment function. For example, Patent Document 1 describes a key holder having a kaleidoscope inside a mascot. According to the present invention, entertainment can be provided in addition to the key holding function and the decoration of the mascot.
The invention described in Patent Document 2 is a key holder that includes a power source, a speaker, a circuit board, and the like inside the mascot, and can mute the use sound of the toilet by generating sound. In addition to the mascot's decoration, it has practicality.

Alternatively, as in Patent Document 3, there is a key holder that can store a key in the same manner as a tri-fold key holder, and at the same time can give various decorations not inferior to a key holder with a mascot.

Tri-fold key holders have the advantage that the keys are housed inside, so that they do not damage other objects when placed in a pocket or the like, but they are thick and bulky when carried. Similarly, a key holder with a mascot as described in Patent Document 1 or 2 is inconvenient to carry depending on the size, shape, and weight of the mascot.
Some people feel hesitant about holding a mascot key holder depending on age, occupation, and gender.
The key holder described in Patent Document 3 can provide a high decorative property without selecting a holder and being bulky as compared with a key holder with a mascot. However, since the key is taken out when the key is used and is stored when the key is carried, taking in and out is complicated.

In order to solve such problems, the present invention provides a holder main body in which both end portions form a semicircular arc opposed to each other, and a fastener used for opening and closing the both end portions of the holder main body. The tool is a key holder configured by joining a dome-shaped lid portion having a concave portion on the surface and a flat bottom portion by a first support column, a second support column, a third support column, and a push-opening unit. In this key holder, the first support column is positioned inside a semicircular arc formed by one end portion of the holder main body, and the second support column is positioned on the outer side of the semicircular arc formed by one end portion of the holder main body with the holder main body interposed therebetween. The third column is located outside the semicircular arc formed by the other end of the holder body, the push-out part is located between both ends of the holder body, And interposed between the lid portion and the bottom portion of the fastener.
In this key holder, at least the holder body is made of a metal having elasticity.
The holder body and the fastener may be made of silver.
In this key holder, the push-out portion is an elliptic cylinder.
Furthermore, in this key holder, the surface of the holder body is decorated.

  According to the key holder provided by the present invention, the key can be carried without being bulky. Moreover, since it has high fashionability that is different in structure and shape from conventional key holders and simple opening and closing operations, it is easy for anyone to use regardless of age, occupation, or gender.

Preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of the key holder (1). As shown in the drawing, the key holder (1) includes a holder body (2) having a shape similar to a heart shape, and a fastener (3). The fastener (3) includes a lid (31) and a bottom (32), and an elliptical recess (4) is provided near the center of the surface of the lid (31). The concave portion (4) gives the key holder (1) decorativeness, and also functions as an anti-slip when the operator puts his / her finger on the fastener (3) during the opening / closing operation.

As shown in FIG. 2, the lid portion (31) and the bottom portion (32) are joined by the first support column (51), the second support column (52), the third support column (53), and the pushing member (6). ing. A holder body (2) is interposed between the lid (31) and the bottom (32), and one end of the holder body (2) is between the first support column (51) and the second support column (52). It is sandwiched between.
The holder body (2) and the fastener (3) are preferably made of a metal such as silver and can provide sufficient strength for carrying the key. Further, the thickness of the holder body (2) is not particularly specified, but it is set to such an extent that it can be passed through a hole (described later) provided in the key.
