Description

[Detailed description of the invention] This invention relates to the creation and improvement of a key chain.

More specifically, the key chain is made of a combination of wire and a rectangular block body having an appropriate thickness.The purpose of the key chain is to easily attach and detach the key to the key chain, and furthermore, to attach and detach the key to the key chain. The holder allows it to be used freely without any hindrance.

The following prior art related to key chains is known.

First, the piano wire is bent into an annular shape several times, adjacent piano wires are pressed against each other, and the key is inserted from the ring end.
The key is configured so that it does not come off from the ring by feeding it deep into the ring, and when it needs to be removed, it must be sent back in the opposite direction to remove it.

Second, a metal rod is formed into a substantially C-shape, and the opening is locked by undulating the locking rod at the opening end with a lifting claw.

Thirdly, a metal rod is formed into a U-shape, and a coiled spring is wound around a locking material at one end of the opening, so that the spring force presses the locking material against the opening side, and at the same time, the locking material resists the spring pressure. The opening side is locked and released by lifting it up and rotating it around the mounting base.

However, all of the above conventional key holders are made of metal and have a relatively narrow opening, so when a large number of keys are attached, both the keys and the holder may become flexible depending on the angle of the key holder. This made it extremely inconvenient to use the key.

In addition, in the case of a keychain with a trigger claw, the trigger claw may get caught on something else while being carried and the lock may come off naturally.
There was a risk of dropping the key.

Furthermore, in the case of a key made of piano wire, the ring end must be pulled up against the spring pressure of the piano wire to insert the key.
It was inconvenient to attach the key.

In order to solve the problems of the prior art as described above, this invention consists of a wire that holds the key, and the wire is combined with a rectangular block body having an appropriate thickness, and the wire end is fixed to the block body. However, the other end is configured to be detachable from the block body by an appropriate configuration.

Specific embodiments will be described below with reference to the drawings.

Embodiment A block body 1 having an appropriate thickness is made of metal or synthetic resin material.

The locking piece 2 is formed by cutting off one end of the block body 1, and the cut surfaces of the two pieces are joined to form the block body 1 into the intended rectangular size.
The locking pieces 2 are formed with uneven locking bodies a and b that lock with the respective joint surfaces, and aim at the meshing position of the joint.

A pin 3 is installed at one end of the locking piece 2, and the pin 3 is inserted into the through hole 4 of the block body 1.
A coiled spring 5 is wound around the lower end of the pin, and a washer 6 is wound around the end of the pin.
The structure is such that the locking piece 2 is always pressed against the block main body 1 side, and one end of the wire 9 is embedded and fixed in one end surface of the block main body 1, and the piece 10 is fixed to the other end. A hole 7 large enough to fit the piece 10 is drilled in the block body side at the joining surface of the locking piece and the block body, and a hole 7 is formed in a position that matches the hole 7 and is fitted on one side of the locking piece 2. A key chain is constructed by providing a stopper groove 8.

Since this device is constructed as described above, the first step is to use the piece 10 at the end of the wire 9.
is released from the block body and the key is inserted and held there.

When the required number of keys are held, piece 1 at the end of the wire
0 into the hole 7 of the block body 1, and the locking piece 2, which has been open until now, is closed around the pin 3, whereby the piece 10 is held by the locking piece.

At this time, the wire is fitted into the locking groove of the locking piece as it is, so both ends of the wire are pulled out from the end face of the block body, and the wire forms a ring through the block body and locks the key. It is something to keep.

In addition, when removing the key from the wire, by lifting the locking piece 2 a little against the spring pressure of the coiled spring 5 of the pin 3 and rotating it toward the release side, the wire can be easily removed from the locking groove, and the piece will be The key can be easily pulled out of the hole and the wire end will be released, so the key can be pulled out from the wire end.

On the joint surface of this locking piece and the block body, locking bodies a and b with concave and convex surfaces that engage with each other are formed, so that the locking piece is always held on the block body side by the spring pressure of the coiled spring wound around the pin. It is pressed against the
Together with the engagement of the concave and convex locking bodies, the locking piece does not easily rotate and come off from the block body, thereby preventing the wire from being unnecessarily released from the block body.

Further, since the wire is highly flexible, the key has more freedom than the wire, so there is no fear that the key holder will interfere with the use of the key.

Since this invention is constructed as described above, it exhibits the following effects.

First, the wire and the block body constitute a key holder, and since the part that holds the key is the wire, by releasing the wire end from the block body, the key can be held on the wire without any problem, and unlike conventional products, the key holder can be held on the wire without any problem. It is much easier to hold the key than with a narrow key, and the same effect is achieved when the key is removed.

Second, the method of locking the wire to the block body, which has an annular wire end, is to rotate a locking piece connected to the block body around a rotating pin, and then drill a piece at the wire end into the block body. It fits into a provided hole, locks with a locking piece, and can be released, making it extremely easy to handle.

Third, when the piece is locked to the block body, the wires fit into the locking grooves formed in the locking piece, so the wires are drawn out from the end face of the block body, and the base of the wire that holds the key There is a structural advantage that there is no risk of twisting.
