Abstract

(57) [Summary] [Purpose] A folding balance for fishing that allows the main body and lateral arms to be strongly fitted together with a simple structure and to be attached and detached lightly. [Structure] A spiral ring portion 6 formed by winding a base portion of a lateral arm 5.
By fitting the inner concaves and convexes inside a plurality of fitting recesses 8 and 9 provided slightly outside of the weight hooking ring 3 provided at the bottom of the main body 2, the two become a male-female fitting like a screw. The balance is assembled, the ring part 6 is detached, the ring part 6 is moved into the weight ring 3, and the lateral arm 5 can be folded by rotating around the ring part 6.

[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable one-sided balance that connects weights, road yarns and Harris in fishing, and acts to balance these. .

[Prior Art] Conventionally, as a balance of this type, a ring for closing a weight hanging ring (a) shown in FIG. 5 is formed by a tubular ring portion (b) directly fixed to a base portion of a lateral arm (actual disclosure). In addition to 60-60 460), the balance shown in FIG. 6 has a horizontal branch E at the bottom of the main body D, and the base of the horizontal arm C is fixed to this with a tubular ring ring (Publication No. 2- No. 123874) is known.

[Problems to be Solved by the Invention] Among the problems described in the related art, in the former case, when the tubular ring ring fixed to the base portion of the lateral arm c is fitted to the weight hanging ring (i), it is separated. It is necessary to fit tightly so that there is no fear, the oval tubular ring ring needs to keep a stable tight fit, and the precision of its inner diameter must be kept very high. Difficult within technical tolerances and expensive to manufacture.

Similarly, in the latter case, a tubular ring ring is used to fix the base portion of the arm c, and it is necessary to keep the manufacturing precision extremely high as in the case of the previous example. The fitting condition may become loose or loose due to accuracy error, wear due to long-term use, shock due to weight landing, etc.

The present invention has been made in view of such problems of the conventional technology. Its purpose is that the side arm is firmly fixed to the main body of the balance so as not to get caught or separated, the use of highly accurate parts in manufacturing technology can be eliminated, and the same material can be used. It is intended to provide a stable fitting and fixing effect by making it with a simpler structure.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, the same wire rod as the lateral arm 5 is threadedly formed on the base portion, and a ring portion 6 having irregularities on the inside is used. When the weight hooking ring 3 at the bottom of the main body 2 is closed, the weight hooking ring 3 has a structure in which it is fitted and fixed to a plurality of fitting recesses 8 and 9 provided slightly outside the weighting hook 3 above the weight hooking ring 3. The opening 7 facing toward the side is formed in a slightly opened state and placed, and while the action of the opening 7 trying to open to the outside is narrowed down by the ring portion 6, the same fitting as with a screw is performed to ensure stable wearing. It is designed to obtain a joint fixing effect. The force at this time is stronger at a position closer to the weight hanging ring 3.

[Operation] After attaching the weight to the weight hooking ring 3 of the main body 2, when attaching the opening portion 7 to the ring portion 6 of the lateral arm 5 base, stable attachment and fixation can be obtained and detached. At this time, it is possible to move the ring portion 6 into the weight hanging ring 3 and fold the lateral arm 5 so as to rotate the link portion 6. It can be easily put on and taken off by twisting the weight hanging ring 3 slightly to the left and right.

Embodiments Embodiments will be described with reference to the drawings. The present invention is composed of two parts, a main body 2 and a lateral arm 5 made of a wire rod. The main body 2 has an upper ring 1 through which a thread is passed and an weight hanging ring 3 at the lower part. The fitting recesses 8 and 9 are formed on the outer side of the weight hooking ring 3 slightly above. The lateral arm 5 is provided with a lateral ring 4 for passing Harris at its end and a ring-shaped ring portion 6 formed in a screw shape with an oval inner diameter at the base. At the time of use, the weight is hooked on the weight hanging ring 3, and then the ring portion 6 is deeply attached to the opening 7 of the weight hanging ring 3 to complete the shape as shown in FIG.

In this state, by pushing the ring portion 6 against the force of opening to the outside of the opening portion 7, the inner concave and convex portions are fitted together while tightening the fitting concave portions 8 and 9, which facilitates the fitting. Wear so that they do not get stuck or come off. ,

The lateral arm 5 is shown in FIG. 2 by rotating the ring portion 6 when the ring portion 6 is disengaged from the opening 7 of the weight hanging ring 3 and is moved into the weight hanging ring 3. The weight hooking ring 3 which can be folded in the same manner is formed to have a size larger than at least the ring portion 6 can pass through.

[Effects of the Invention] The present invention, which is configured as described above, has the following effects. With two similar wire rods, it has the simplest structure with the fewest number of parts. It does not require particularly high precision in manufacturing, and it can be easily and inexpensively manufactured. The arm 5 can be fitted tightly, does not easily get jammed or comes off, and even if the fit is strong, it can be put on and taken off relatively lightly.

Claims (1)

[Scope of utility model registration request] 1. A balance in which a ring portion 6 which functions to close the weight hanging ring 3 is directly installed on the base of the lateral arm 5 of the balance. A ring portion 6 having an oval inner diameter and formed in a screw shape is provided on the base portion of the wire forming the lateral arm 5, and fitting concave portions 8 and 9 are fitted to correspond to the concave and convex shape on the inner side. It is provided slightly outside the upper part of the ring so that the concavo-convex shape inside the ring part 6 strongly tightens the fitting recesses 8 and 9 against the force of opening the opening 7 of the weight hooking ring 3 outwardly. As well as
The ring portion 6 is detached and moved into the weight hanging ring 3, and the ring portion 6 is rotated with the deep portion of the weight hanging ring 3 as the center axis.
A foldable balance that can be folded to produce rice.
