Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a key chain for carrying keys.

(Prior Art) As an example of a conventional key chain, as shown in FIG. 5, there is a known key chain in which both ends of a rod-shaped body 61 are bent so as to approach each other, and the ends are connected by a connecting member 62. . The rod-shaped body 61 is formed so that both ends are brought close to each other with a certain interval,
Insert the key between the two ends (hereinafter referred to as the opening),
Both ends are connected by a connecting member 62 so that the key can be held. Therefore, the connecting member 62 and the rod-shaped body 61 can connect both ends of the rod-shaped body 61 that are close to each other with the connecting member 62, and at the same time,
It must be constructed so that an opening can be opened to insert the key.

A conventional connecting member for this purpose and the tip of a rod-shaped body inserted into the connecting member have a structure shown in FIG. 6 or 7.

FIG. 6 shows a connection structure using screws, and as shown in the figure, one end 63 of the rod-shaped body 61 is formed with a male thread, and the connecting member 62 has a female screw thread on one side of the hollow portion to which the male thread is screwed. 64 was formed. Only one side of the connecting member 62 is formed with an internal thread, the other side being left hollow and the other end 65 of the rod-shaped body simply inserted.

Therefore, by rotating the connecting member 62, the male screw 63 and the female screw 64 can be screwed together to connect the ends 63 and 65, and by rotating the connecting member 62 in the opposite direction, the screwing can be removed and the connection can be completed. Part 6
2 can be shifted to the position of the other end 65 of the rod-shaped body 61 and opened.

However, there were cases where the connecting member 62 rotated and became disconnected while the device was being carried, and the key inserted into the rod-shaped body came off.

FIG. 7 shows an example in which a spring 66 is used.
In this case, the connecting member 62 has its hollow portion connected to the partition wall 6.
Partitioned into two by 7, one end 68 of the rod-shaped body and the partition wall 67
A coil spring 66 is inserted between the two. That is, the connecting member 62 is pressed against the other end 69 of the rod-shaped body by the pressing force of the coil spring 66, and the tip 69 is inserted into the other partitioned hollow part of the connecting member 62 to connect both ends of the rod-shaped body. be. It can be opened by shifting the connecting member 62 against the pressing force of the spring 66.

In this case as well, since the spring 66 is simply pushing the coupling member 62, when a force is applied to move the coupling member 62 downward in the drawing, it may shift and open, causing the key to come off.

(Problem to be Solved by the Invention) It is an object of the present invention to provide a key holder that is easy to put the key in and does not accidentally come off while the key is being carried, while eliminating the drawbacks of the conventional key holder described above. .

It is attached to the main body member 1 with.

Furthermore, in the present invention, a small protrusion 15b is formed on one end of the rotating shaft 22 of the opening/closing member 2, and a small protrusion 15b is formed on the other end of the shaft 15, and two notches 24, 24 are formed on the other end for inserting the small protrusion. I'm letting you do it.

In addition, the second invention has a decorative member 5 in the above structure.
The decorative member 5 has a through hole 51 through which the shaft 15 and the rotating shaft 22 pass,
The shaft 15 and the rotating shaft 22 are passed through the hole 51 and are rotatably attached.

(Function) In the present invention, the space between the tip of the locking portion 14 of the main body member 1 and the tip of the shaft 15 is open. An opening/closing member 2 is rotatably attached to this open portion.

This opening/closing member 2 has a rotating shaft 22, the tip of which is abutted against the tip of the shaft 15 of the main body member, and is rotatably attached by attachment members 3 and 4. Furthermore, since the opening/closing member 2 has a rotary rod 23 whose tip is opposed to the tip of the locking portion 14, the locking portion 14 is normally closed by the rotary rod 23, and the center of the rotation shaft 22 is By rotating the locking part 14, the tip of the locking part 14 is opened, and the key can be inserted into the locking part 14 from there.

This opening/closing member 2 has a rotating shaft 2 relative to the main body member 1.

To remove the key, move the opening/closing member 2 to remove the small protrusion 15b from the notch, rotate it, shift the rotating rod 23 from the position facing the tip of the locking part 14, and open the locking part 14. good.
By inserting the small protrusion 15b into the other notch 24, the open state can be maintained.

(Embodiment) Fig. 1 is an exploded view of an embodiment of the present invention, and as shown in the figure, this key chain is attached to a main body member 1 for holding a key, and a missing part of this main body member, An opening/closing member 2 that opens and closes the missing part, a threaded rod 3 that rotatably attaches the opening/closing member 2 to the main body member 1, and a coil spring 4.
It is composed of five members: and a decorative member 5.

The main body member 1 includes arm portions 11 and 12 arranged in parallel.
One end of a hollow shaft 15 is fixed to the tip of one arm part 11 of a locking part 14 which is connected by a connecting part 13 whose one end side is curved to form a substantially U-shape. The arm parts 11, 12 and the connecting part 13 are made by bending a single round rod. Its shape is not limited to the substantially U-shape shown. The shaft 15 is a hollow member, and the arm portion 11
In this embodiment, the flange 1 is fixed to the tip of the flange 1.
6 is used.

When forming the locking part 14 into a substantially U-shape, one of the two arm parts 11 and 12 (the one that does not fix the shaft 15) is made shorter than the other arm part 11, and its tip 12a is It remains at a lower position than the tip of the other end 11. Also,
The shaft 15 is also not long enough to extend between both arm parts 11 and 12, but its tip 15a remains at a position on the right side in the drawing of the extension of the arm part 12. .

That is, the main body member 1 of this key chain is formed from a round bar into a substantially U-shape, and a part of the shape is formed by connecting the two ends of the main body member 1 with a shaft 15, and the end part of the arm part 12 and the shaft 1.
It has a shape that lacks the tip part of 5.

A small protrusion 15 is provided at the tip 15a of the shaft 15 in this embodiment.
As shown in FIG. 3, a stopper 17 is provided on the inside of the hollow portion of the distal end portion, which is formed so as to make the inner diameter of the hollow portion smaller.

It is desirable that the shaft 15 and flange 16 be formed integrally.

The opening/closing member 2 is formed in a shape that supplements the missing portion of the main body member 1 described above. This opening/closing member 2 includes a disk 21 having the same diameter as the flange 16.
A hollow rotating shaft 22 having the same diameter and short length as the shaft 15 is attached to the shaft 15, and a locking portion 14 is attached to the edge of the disc 21.
It has a shape in which a rotating rod 23 made of the same round rod is attached.

FIG. 4 shows this opening/closing member 2 viewed from the rotating shaft 22 side, and as shown, two notches 24 are formed from the tip of the rotating shaft 22. This notch 24 is large enough to allow insertion of the small protrusion 15b of the shaft 15 described above.

The positional relationship between the two notches 24 is as shown in FIG.
Two positions are selected to insert the small protrusion 15b: a position rotated by 180 degrees and a position rotated by 180 degrees.

This opening/closing member 2 is rotatably and slidably attached by a mounting member consisting of a threaded rod 3 and a spring 4 with a rotating shaft 22 abutting against the shaft 15. Therefore, when the opening/closing member 2 and the main body member 1 are combined, a U-shaped shaft is formed at both upper ends. The disc 21 of the opening/closing member 2 has the same outer shape as the flange 16, but has a female thread instead of a hole in the center (not shown).

The mounting member for attaching the opening/closing member 2 to the main body member 1 is a threaded rod 3 which is screwed into a female thread provided on the disk 21 through the hollow portions of the shaft 15 and the rotating shaft 22 to be fixed, and a coil spring 4. It is configured. One end of this threaded rod 3 is provided with a head 31 in which a plus or minus groove is formed, and the other end is provided with a male thread 32.

The coil spring 4 can be inserted into the threaded rod and into the shaft 15, and the stopper 1
It has a diameter that can be stopped at 7. This is arranged around the threaded rod 3 as shown in FIG. 3 when the opening/closing member 2 is attached to the main body member 1 using the threaded rod 3. Both ends thereof are located between the stopper 17 and the head 31 of the threaded rod 3, and apply a force to press the rotating shaft 22 of the opening/closing member 2 against the shaft 15.

The decorative member 5 has a through hole 51 through which the shafts 15 and 22 pass.
It is a plate material having an end portion of the plate, and the other end is shaped appropriately so that any decoration can be attached thereto. This decorative member 5 is unnecessary if it is only used to hold a key. It is provided to hide the abutment points of the shafts 15 and 22 and to attach decorations as desired.
The flange 16 and disk 21 serve to position the decorative member 5, as shown in FIG.

To assemble this, the through hole 5 of the decorative member 5 must be
Insert the shaft 15 from one side of 1, and insert the rotating shaft 2 from the other side.
2, the threaded rod 3 into which the coil spring 4 has been inserted is passed through the shaft 15 from the flange 16 side, and its threaded portion 32 is screwed into a female thread (not shown) of the disk 21.

The tip of the threaded rod 3 is screwed into the disc 21 and fixed, and the coil spring 4 is between the tip of the shaft 15 and the head 31 of the threaded rod 3, so the opening/closing member 2
is attached so as to be pressed against the main body member 1. Since the rotating shaft 22 of the opening/closing member 2 is inserted into the threaded rod 3, it can be rotated around the rotating shaft 22. However, as described above, the small protrusion 15b on the tip 15a of the shaft 15 is large enough to fit into the notch 24 of the rotating shaft 22, and since the opening/closing member 2 is pressed against the shaft 15 by the spring 4, it cannot be rotated. When the small protrusion 15b comes to the position of the notch 24, it is automatically inserted and does not rotate.

Since the positional relationship between the small protrusion 15b and the notch 24 is as described above, the opening/closing member 2 is stably held on the main body member 1 when the rotating rod 23 is in the position shown in FIG. When taking out the key,
Once the opening/closing member 2 is moved against the tension of the coil spring 4, the small protrusion 15b is removed from the notch 24, the opening/closing member 2 is made rotatable, rotated 180 degrees, and the small protrusion 15b is inserted into the other notch 24. stabilize. In this state, the rotary rod 23 is 180 degrees from the state shown in FIG. can do.

[Effect of idea]

As described above, in the present invention, the opening/closing member is rotatably attached to the partially chipped part of the main body member, so by rotating the opening/closing member, the chipped part is opened/closed and the key is put in and taken out. It is structured as follows. Therefore, while the opening/closing member can be rotated to open the chipped portion of the main body member to hold the key, it will not come off unless rotated. Moreover, since the rotation is forcibly suppressed by the small protrusion, the notch, and the attachment member that attaches the opening/closing member to the main body member, there is no risk of the key accidentally coming off while being carried or used.
