In addition, as the core material (16), a flexible material is preferable, such as a knit cord (see Figure 11), a twisted cord (
(see Fig. 12), flexible wire made by combining many short metal wires (see Fig. 13), braid (see Fig. 13),
Known core materials such as (see Figure 4) can be used.

In addition, if at least the double-faced teeth (15, 15) of the fastener element row (11), the slider (13), and the separator (14) are made of metal and coated with gold plating, silver plating, or nickel, a high-class keychain can be obtained. becomes.

The slider (13) used in this invention may be of a free type without a locking mechanism, or may have a lock to prevent the meshing teeth (15, 15) from spontaneously separating. It may have a mechanism. As the slider (13) of the type having a locking mechanism, for example, the decorative pull (I2) is the slider (13).
Decorative pull (12), which is an auto-lock type that is automatically locked by a spring-loaded stop claw when it becomes free from the pull locking part (I7).
There are semi-automatic types that are equipped with a cam or pin and are locked only when the decorative handle (12) is tilted, and other types that are shoulder-stop types.

Regarding the relationship between the decorative pull (12) and the slider (13), the decorative pull (12) may be non-removably attached to the slider (13) via the pull locking part (17). , move the decorative pull (12) to the slider (1
A type of slider that can be removably attached to 3) is preferable, and in this case, the decorative pull (12) can be retrofitted or replaced as a decorative pull of various tastes, so it can be used as a key chain with added decoration. This is preferable.

The separation tool (14) includes a box (20) attached to one end of the fastener element row (11) via a box rod (19), and a box (20) attached to the other end of the fastener element row (11).
Although the known separable fitting tool is shown as an example, it is not limited to this, and the point is that the fastener element row (11)
) may be separated as long as it allows both ends to be connected and separated.

The stopper (18) has a U-shape with an open bottom, and may be made of synthetic resin or metal, but it is preferable that the legs (22, 22) have elasticity. .

The lower ends of the leg pieces (22, 22) have locking protrusions (23, 23) that protrude inward. This stopper (18) is used by being fitted from above so as to straddle the box pin (19) and insert pin (21) in front of the box body (20) of the separation tool (14). Then, even if the slider (13) is lowered unexpectedly, the slider (13) will not be lowered to the position of the box (20) by the stopper (18), and as a result, the insert pin (21) will be lowered from inside the box (20). ) will not come off, the ends of the fastener element row (11) will not separate even if the slider (13) is lowered, and the key (K) will not come off unexpectedly.

FIG. 2 shows another embodiment of the stopper (18), in which the stopper (18) of the previous embodiment is fitted from above, but the stopper (18) of this embodiment is fitted from above.

The key holder (10) according to the present invention has the above-described configuration, and its use involves moving the slider (13) through the fastener element row (11) to the position of the separating tool (14).
is pulled down in the direction in which it opens, and as shown in FIG. 3, the insert pin (21) is pulled out from inside the box (20) via the slider (13). Then the fastener element row (11
) is in the state of a chain, and the key (K) is passed through the hole or double ring (WL) from the insert pin (21) side, which is perfect, through this fastener element row (11), and then the fastener element The row (11) is bent into a U-shape and the insert pin (21) is inserted into the box body (20) via the slider (13).
). Then, by holding the decorative handle (12) and sliding the slider (13) upward, the double-sided teeth (15, 15) are engaged as shown in Fig. 1, and the key (K) is pressed.
is held in the loop part (lla) of the key chain (10). Then, as shown in Figure 4, the stopper (18)
is used by fitting and engaging in front of the box body (20) of the separating tool (14). Therefore, as shown in the same figure, the slider (1
3) unexpectedly lowers, the slider (13) will stop at the position up to the stopper (18), and the separator (14) will not separate, ensuring that the key (K) is securely attached to the key chain (lO
) will be held.

Effects of the Invention According to the present invention, firstly, the loop portion for holding the key is formed by bending a row of fastener elements, and the row of loop fastener elements is engaged with each other.
Since it includes a slider that opens and a separation tool provided at the lower end of the row of loop fastener elements, it is possible to obtain a luxurious feel that is completely different from conventional key chains, and the slider allows the size of the loop part to be varied. A sense of play is added by providing a separating tool to separate or connect the ends of the fastener element rows in the loop section, making it a key chain that fits in with modern times.

Second, the part that holds the key is made by bending one fastener element row into an inverted U shape to form a flexible loop part, which can be bent as desired, so that it can be used to hold the key and It does not become bulky even when placed in a pocket or handbag, and the size of the loop can be adjusted to the optimum size depending on the size or number of keys to be held using the slider. have

Thirdly, with the fastener element row closed, the stopper is removably fitted in front of the separating tool, so even if the slider falls unexpectedly, the stopper will prevent it and the slider will go down to the position of the separating tool. As a result, both ends of the fastener element row will not separate, and the key will not be accidentally removed from the key chain.
