Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a novel and easy-to-use key chain for holding keys and the like.

Conventional Technology In the past, as shown in Fig. 15, a decorative body (2) is attached directly or indirectly to one side of a metal hold ring (1) through a chain, etc., and a key ring that can be opened and closed is attached to the other side. The one with (3) attached is widely known as a hold ring type key chain.

Problems to be Solved by the Invention By the way, this hold ring type key chain has a simple ring shape, and the hold ring (1) is a simple ring to which the ring-shaped key ring (3) is attached, so it has a design problem. However, it was also unsatisfactory in terms of functionality.

Also, if the hold ring (1) is made a little larger in consideration of the number or size of keys to be held, since it is made of metal and has a fixed shape, it will be bulky when stored in a clothes pocket or handbag. The problem was that it was difficult to carry around.

The present invention was made with attention to the above-mentioned problems, and compared to the conventional hold ring type key chain,
Our objective is to provide a key chain that has a completely different image, has a sense of luxury and playfulness, and is not bulky when carried around.

Means for Solving the Problems According to the present invention, the above-mentioned problem is achieved by forming a core material having flexibility at a constant pitch with double-sided interlocking teeth (1B, l[i) whose meshing portions are symmetrical in the pitch direction of the interlocking teeth. (17), one fastener element row (11) fixed to the fastener element row (11), a slider (13) that engages and releases the fastener element row (11) by bending it into a loop shape, and a slider (13) which is bent into a loop shape. A bottom stopper (14) is fixed to the lower end of the engaging row part following the loop part (11a) of the fastener element row (11), and the lower end part cannot be separated. This problem is solved by providing a key chain characterized by comprising a key ring (15) that is hung over the loop part (11a) of the fastener element row (11).

By engaging and disengaging the fastener element rows using the action slider, the loop portion can be freely deformed by making it larger or smaller. Further, a key ring is interposed in the loop portion, and a key is held in the key ring.

EXAMPLES Hereinafter, the present invention will be specifically explained based on examples shown in the drawings.

FIG. 1 shows an embodiment of a key chain (10) according to the present invention, and the key chain (10) has -1 rows of fastener elements (11) and a decorative handle (12) that also serves as a decoration. A slider (13) and a lower stop that is fixed to the lower end of the engaging row part following the loop part (11a) of the fastener element row (11) bent into a loop shape, making the lower end part inseparable. tool (14), and a key ring (k) that hangs over the loop portion to hold the key (k).
15). This key chain (10
) is an inverted U for the - fastener element row (11).
The key (k) is held through a key ring (15) consisting of a ring which is bent into a letter shape to form a loop part (11a) and can be opened into the loop part (11a).

The fastener element row (11) has double-sided fastener teeth (18,
18) are arranged at a constant pitch and fixed to the core material (17). This double-sided tooth (lθ).

16), for example, as shown in FIGS. 6(A) and (B), metal fasteners having protrusions on the front and back surfaces, which are both sides of the engaging part, and coiled fastener elements. [See Figures 7 (A) and (B)], zigzag-shaped fastener elements in which each tooth is connected at the reversed part to form a zigzag shape [See Figures 8 (A) and (B)], and injection There are double-sided type fasteners such as the type [see Figures 9 (A) and (B)] or the extruded type [see Figures 10 (A) and (B)], and these known double-sided fasteners can be used. I can do it. The core material (17) is preferably a flexible material, such as a knit cord (see Figure 11), a twisted cord (see Figure 12), or a flexible wire made by combining many short metal wires (see Figure 12). Known core materials such as (see FIG. 13) and braid (see FIG. 14) can be used.

In addition, at least the double-faced teeth (16, 16) of the fastener element row (11), the slider (13), the lower stop (14), and the key ring (15) are all made of metal,
If gold plating, silver plating, nickel plating, etc. are applied, the key chain will have a sufficiently heightened sense of luxury.

The slider (13) may be a free type that does not have a locking device, but it may have a locking device (20) that prevents the engaged fastener element rows (11) from engaging and disengaging naturally. is preferred, for example a pull (12) as shown in FIGS. 2 and 3.
Even if it is an auto-lock type that is automatically locked by a locking pawl (23) biased by a spring (22) when the slider (13) becomes free from the pull locking portion (21). Alternatively, the handle (12) may be of a semi-automatic locking type, which is locked only when the handle (12) is laid down, and a cam or pin is provided on the handle (12). Regarding the relationship between the slider (13) and the pull handle (12),
The pull (12) may be non-removably attached to the slider (13) via the pull locking part (21), but the pull (12) may be detachably attached to the slider (13) afterwards. A type of slider that can be used as a decoration may also be used, and in this case, the handle can be made into a decorative handle of various tastes and can be retrofitted, so it is preferable as a key chain with added decoration.

The key ring (15) may be a double ring as shown in FIG. 1, or may be a card ring type that can be opened and closed from side to side as shown in FIG. In addition, as shown in FIG. 5, there is a key ring in which a compression coil spring (24) is interposed in a cylindrical ring, and the lock piece (25) is opened along the ring against the spring (24) with the fingers. You can. In short, it is sufficient if the key ring can be opened elastically.

By configuring the key holder (10) in this way, the loop portion (11) of the fastener element row (11)
A key ring (15) is interposed in a), and a key (k) is hung on this key ring (15). Since the fastener element row (11) is engaged and separated by the slider (13), the loop portion (11a) can be made larger or smaller.

Effects of the Invention As described above, according to the present invention, firstly, the main body of the key chain is bent into a loop shape by a fastener element row, a slider for engaging and releasing the fastener element row, and a lower stopper. Because of this structure, it gives a unique sense of luxury that has never been seen before, and the conventional hold ring part is formed by the loop part of the fastener element row, and the loop part can be enlarged by sliding the slider.
Since it can be made smaller and can be changed freely, it not only allows the user to adjust the state in which the key ring is latched, but also evokes a sense of play.

Secondly, the loop-shaped fastener element row that makes up the hold ring part is flexible, and the key ring is hung on the loop part of the fastener element row so that it can move freely, so it can be used as a pocket for clothes. Alternatively, when storing it in a handbag or the like, it can be freely deformed and folded according to the size and shape of the space in which it is stored, making it convenient to carry.

Thirdly, the key to be held is not attached to the loop part of the fastener element row in which the double-sided teeth are attached at a predetermined pitch, but is passed through the key ring that is hooked to this loop part. It has various advantages such as not being worn out or damaged by the key that holds the locking teeth.
