Description

[Detailed Description of the Invention] Technical Field The present invention relates to a flat key chain (or key case).

PRIOR TECHNOLOGY Conventionally used key chains consist of a locking ring with an opening that can be opened and closed, and a suitable ornament is connected to this using a chain or the like, and a connecting hole in the key head is connected to the locking ring. A locking ring is inserted into the key to attach the key, or a locking metal fitting is provided on the inside of a foldable cover made of leather, etc., and the locking metal fitting is inserted into the connection hole in the key head to attach the key. The most common type is one that has a .

However, in the former example, the locking ring, chain, and accessories that form the keychain are connected in a chain as a whole, so the overall shape is not fixed, that is, it is deformable. It has the disadvantage that it does not fit well when placed in a bag such as a pocket or bag.

In the latter example, since the key is housed in the cover, the overall shape is somewhat constant and there is no drawback like the former, but it has another drawback of increasing the overall thickness. There is.

Purpose of the present invention The present invention was developed in view of the above-mentioned conventional circumstances.The purpose of the present invention is to have a uniform overall shape and a small thickness, so that it can be easily stored in a pocket of clothes, etc. The purpose is to provide a good flat key chain.

Structure, operation, and effect of the present invention In order to achieve the above object, the present invention was constructed as follows. That is, the key holder is configured to store a flat key holder in a key holder storage recess formed on one side of a flat main body, and the key holder includes a key insertion/extraction side edge on its front surface. A key-sliding type key storage recess having a planar shape that is substantially the same as that of the key, and a key holding portion that covers a part of the key storage recess to prevent the key from coming off in the direction perpendicular to the plate. between the main body base and the key holder base, connecting spring means for slidably connecting the key holder to the main body in the key insertion/removal direction and biasing the key holder to the storage position; The key holder is configured to be provided with a guide means for lifting the key insertion side edge of the key holder relative to the main body when the key holder is pressed against the main body in the key extraction direction.

In the above configuration, when the key is extracted, when the key holder is pressed against the main body in the key extraction direction, the edge of the key holder on the key extraction side lifts up from the main body 2, as described above, so the key is removed in this state. It can be easily pulled out from the key holder by pinching it. On the other hand, when storing the key, the key is held down by the key holding part, so that the key is prevented from coming off in the direction perpendicular to the plate, and the entire key holder is stored in the key holder storage recess of the main body. Further, since the key holder is held in the storage position relative to the main body by the connecting spring means, the key is reliably held within the key storage recess of the key holder.

According to the above configuration, since the key is stored flatly in the key storage recess of the key holder, the thickness of the key holder only needs to be slightly thicker than that of the key, and the main body is Since it is only necessary to have a thickness sufficient to accommodate the key holder, the overall thickness of the key holder can be made very small, and furthermore, the overall shape of the key holder remains constant when the key is stored. There is. Therefore, the intended purpose of the present invention can be fully achieved.

Furthermore, according to the above configuration, the key can be inserted and removed by simply sliding the key holder against the main body, and therefore, the operation is very simple, and as described above, In the key storage state, the key has the advantage of being reliably held within the key storage recess of the key holder.

Embodiments Hereinafter, embodiments of the present invention will be specifically described based on FIGS. 1 to 5.

In the figure, 1 is a key holder, and K is a key stored in the key holder 1.

The key holder 1 is composed of a generally rectangular and flat main body 2 and a flat key holder 4 that is housed in a key holder storage recess 12 formed on one side of the main body 2. .

The key holder 4 is slightly thicker than the key K, and the main body 2 is thin enough to accommodate the key holder 4 flatly.

Key storage recess 3 formed in key holder 4
is a square part 3a in which the head Ka of the key K is stored.
and a narrow part 3b in which the foot part Kb of the key K is accommodated. The square portion 3a includes the key insertion/removal side edge of the key holder 4, and is open to the key insertion/removal side edge 4a, so that the key K can be inserted into the key storage recess 3 from this portion. It is now possible to store it.

The key holder 4 is provided with a key holding plate 5 on the side surface where the key storage recess 3 is formed, that is, on the front surface. As clearly shown in FIG. 1, this key press plate 5 has a cutout that has approximately the same shape as the key K, and most of the key K is exposed without being covered. On both sides of the elongated portion 3b, a portion of the elongated portion 3b is projected like an eave to form key press portions 5a, 5b. Therefore, since the key holding parts 5a and 5b cover a part of the elongated part 3b of the key storage recessed part 3, the key K does not slip out in the right angle direction of the key holder 4, that is, in the front direction. Note that the key holder 4 may be formed integrally with the key press plate 5, or the key press plate 5 may be formed separately.

On the other hand, a finger-pressing part 6 is formed at the base B of the key holder 4 so as to protrude toward the front surface, and the key holder 4 can be slid with respect to the main body 2 via the finger-pressing part 6. .

On the other hand, the main body 2 has the key holder housing concave portion 12
A fencing means is provided around the area. That is, this enclosing means includes a pair of long side walls 2c, 2d along the sliding direction of the key holder 4 with respect to the main body 2, and a main body base A.
It consists of a side plate 2a provided on the side and a raised portion 11 provided on the key extraction side of the main body.

The following structure is adopted between the base A of the main body configured as described above and the base B of the key holder 2 in order to connect the key holder 4 to the main body 2 so as to be slidable in the key insertion/removal direction. There is.

That is, a guide groove 9 having an inverted T-shape in the broken plane is formed on the bottom surface of the key holder storage recess 12 of the main body base A, and a connecting spring means 7 is provided on the bottom surface of the key holder base B, and this connecting spring The means 7 is inserted into the guide groove 9.
It is configured to be able to slide freely along the More specifically, the connecting spring means 7 is approximately U-shaped, as clearly shown in FIG.
a, and a sliding portion 7b fitted into the guide groove 9.
and the insert buried portion 7a and the sliding portion 7b.
and a connecting portion 7c that connects the two. As clearly shown in FIG. 3, in order to insert the sliding portion 7b of the connecting spring means 7 into the guide groove 9, the side plate 2a is constructed separately from the main body 2.
After the connecting spring means is assembled into the guide groove 9, the connector a is assembled into the main body 2 at a predetermined position. That is, this side plate 2a has a generally inverted T-shaped insertion portion 2b at its lower portion, and this insertion portion 2b is adapted to be inserted into the guide groove 9.

Further, when the key holder 4 is slid in the key extraction direction with respect to the main body 2, the key removal side edge 4a of the key holder 4 is lifted up with respect to the main body 2. An inclined surface 10 is formed on the bottom surface of the holder storage recess 12, and an inclined surface 8 corresponding to the above-mentioned inclined surface 10 is formed on the bottom surface of the key holder 4. Therefore, as shown in FIG. 5, when the key holder 4 is slid with respect to the main body 2 in the key extraction direction, the inclined surface 8 of the key holder 4 rides on the inclined surface 10 of the main body 2, and as a result, the key is removed. The side of the key removal/insertion edge 4a of the holder 4 comes to rise above the main body 2. Therefore, in this state, the key K can be easily picked out with a finger as shown in the figure.

Although the cross section of the stored state of the key is not shown, in FIG. Holder storage recess 1
It will fall within 2. Therefore, at this time, the inclined surface 10 of the main body 2 and the inclined surface 8 of the key holder 4 are separated. When the key holder 4 is stored in the key holder storage recess 12 of the main body 2, the key holder 4 is biased and held in the stored position by the connecting spring means 7, so that the key holder 4 is biased and held in the storage position by the connecting spring means 7. 4a side does not easily rotate in the direction of lifting up with respect to the main body 2, and the existence of the raised portion 11 of the main body 2 prevents the key K from moving in the extraction direction. The key is securely held within the key storage recess 3 of the key holder 4.

According to the embodiment with the above configuration, since the key holder 4 and the main body 2 are provided with connection means or inclined surface means 8, 10, etc., the thickness of the key holder increases to some extent, but basically the key holder is The body 4 only needs to be thick enough to store the key K in a flat manner, and the main body only needs to be thick enough to store the key holder 4, so the overall thickness of the key holder is made sufficiently thin. Moreover, when the key is stored, the shape can be kept constant like a single plate, and the intended purpose of the present invention can be achieved. moreover,
In particular, according to this embodiment, the operation of inserting and removing the key basically requires only sliding the key holder 4 relative to the main body 2, and the operation is very simple.
Further, when storing the key, there is an advantage that the key can be held securely as described above.

In the above embodiment, the inclined surface means 8 and 10 are used as guide means for lifting the key holder 4 with respect to the main body 2 when the key K is extracted, but instead of this, for example, the key holder The above object can also be achieved by providing trunnions on both sides of the main body 2, while providing slots into which the trunnions fit on both sides of the key holder storage recess 12 of the main body 2, and forming these slots at an angle. can be achieved.

The key case according to the present invention is also effective when attached to a pouch, pouch, driver's license case, card case, etc.

Further, a specific example of manufacturing the key chain according to the above embodiment is shown in FIGS.
