Description

[Detailed explanation of the idea] "Industrial application field" This invention relates to key fishing gear.

``Prior Art'' Conventionally, a key holder 1 or a circular ring shown in FIG. 5 has been used as a key holder to which a single key or a plurality of keys can be attached.

The key holder 1 has an insertion piece 2 and a surrounding piece 3 made of an elastic plate material with a flat cross section such as a metal plate or a hard resin plate, and is manufactured by punching a stainless steel plate, for example. The insertion piece 2 has a tip 2a
and from the proximal end of the insertion piece 2 to the distal end 2a.
A surrounding piece 3 is extended so as to surround it. A flat bulging piece 4 is formed at the base end of the surrounding piece 3,
A narrow passage 5 is formed between the outer side 2b of the insertion piece and the inner side 4a of the bulging piece 4. Multiple keys 6,...
... usually forcefully expands the narrow passage 5 for the key holder 1 via a wall 6b formed in the inner hole 6a or a ring 7 made of a metal wire wound in a circular shape after passing through the wall 6b. It is inserted and fished.

``Problem to be solved by the invention'' As mentioned above, in the case of the key holder 1 having a surrounding frame body, it is preferable that the key 6 inserted in one portion does not come off unnecessarily, but only the desired key is allowed to come off. is extremely difficult.

Therefore, for example, if you are fishing for car keys, you will have to drive the car while holding many other unrelated keys, and you will have to endure the discomfort of the keys hitting your knees.

The present invention was developed in view of the problems of the prior art, and its purpose is to remove a desired key from a key chain of a fishing base without having to remove the fishing part from the key chain. The purpose of the present invention is to provide a key fishing tackle that can be used and returned to its original state.

"Means for Solving the Problem" In order to achieve the above object, the key fishing gear of the present invention includes a first sleeve having a circumferential locking groove in a predetermined portion of the inner wall on the fishing side with respect to the fishing base. , an expandable and contractible upright wall that surrounds the distal end surface that abuts the first sleeve through a slit inserted into the sleeve is protrudingly provided, and the outer edge of the distal end of the upright wall is engaged with the circumferential locking groove. A clamp having a second sleeve, which is a key hanging side, which is provided with a protrusion and an expansion taper formed on its inner edge, and a key hanging part that is inserted from the rear end side of the second sleeve via an elastic spring. and,
The clamp bolt is assembled from the tip side to the clamp, which has a collar portion that abuts against the tip of the upstanding wall and a taper that follows the taper and is shaped into a head neck portion.

"Operation" When the clamp is pushed relatively forward against the elastic spring while holding the second sleeve, the taper on the inner edge of the upright wall separates from the taper of the clamp bolt head, allowing the upright wall to contract in diameter. Further, when the pushing force is released, the clamp and the clamp bolt retreat, and the upright wall relatively moves forward along the taper of the clamp bolt until it hits the flange of the clamp bolt head, returning to the old position.

Therefore, in the above state, the upright wall of the second sleeve can be inserted into and removed from the first sleeve, and in the state described later, the upright wall inserted in the first sleeve can be inserted into the locking circumference. It is locked in the groove and combined with the first sleeve, so that it cannot be pulled out unnecessarily.
Therefore, if the first sleeve is connected to the fishing base and the key is hung from the second sleeve, only the key hanging part is separated and detached by pulling out the second sleeve from the first sleeve. and can be recombined.

In other words, a desired key can be removed from the fishing base with one touch while only the fishing part remains, and reinstallation can also be done with one touch.

"Example" Examples will be described with reference to the drawings.

In FIGS. 1, 2, and 3, the first sleeve 8 has a locking circumferential groove 9 at a predetermined portion of its inner wall, and a connecting portion 10 to the fishing base.

In the illustrated example, the coupling portion 10 is a perforation 11 for coupling to the key holder 1 via the ring 7.

A second sleeve 14 is attached to the first sleeve 8, which is assembled in such a manner that a surrounding expandable and contractible upright wall 13 is inserted through slits 12 protruding from the distal end surface and abuts against each other.

The tip of the upstanding wall 13 is provided with a protrusion 15 in the shape of a bulging edge, and the inner edge is formed into an expanding taper 16. Second sleeve 14
is a penetrating body, into which a clamp 19 is inserted from the rear end side via an elastic spring 18 fixed to the seat 17, and from the front end side, there is a flange 20 against which the tip of the upright wall 13 abuts, and a flange portion 20 as described above. A clamp bolt 22 having a taper 21 along the taper 16 shaped at the neck of the head is inserted.

The clamp 19 and clamp bolt 22 are integrally assembled using a cap nut portion 23 of the clamp 19. Now, the integrated clamp 19 and clamp bolt 22 shown in FIG.
When pressed against the elastic spring 18 while holding the clamp bolt 22, the clamp bolt 22 moves relatively forward, and the upright wall 13, which had been expanded in diameter, is contracted as the taper 16 contacts the large diameter part of the taper 21. insertion into the first sleeve 8 is permitted. Then, while maintaining this position, insert the above-mentioned integral part into the first sleeve 8 (Fig. 4a) and push it to the end (Fig. 4b).

Next, when the above-mentioned pressing force is released, the elastic spring 18
As a result, the clamp bolt 22 is moved back, and the upright wall 13 is in an expanded diameter position as shown in FIG. You won't be able to get out of it.

Breaking out is done by going into the reduced diameter position described above.

The aforementioned locking is due to the wedge action of the head of the clamp bolt 22 against the upright wall 13, but excessive wedge action makes release difficult. However, in this case, the tip of the upright wall 13 abuts against the flange 20 and prevents the clamp bolt 22 from being wedged in any further, so there is no need to worry about this.

Due to this arrangement, the clamp 19 is provided with the key hanging portion 24 and may be subjected to excessive tensile force, but there is no problem in releasing the lock.

In the illustrated example, the key hanging portion 24 has a hole 25 through which the key 6 is hung via the ring 7.

"Effects of the invention" Since the present invention is constructed as described above,
This produces the following effects.

(1) A desired key can be separated from the key hanging part with one touch without having to dismount the fishing part attached to the fishing base, and can be re-inserted with one touch, making it extremely difficult to remove. This is particularly suitable when a large number of keys are attached to a key holder.
