As shown in FIGS. 1 and 2, the guide mechanism 2 is for guiding the linear bodies LX1 and LX2, and includes a finger-passing ring 10 and a surrounding member 20 fixed to the finger-passing ring 10. ..

The linear bodies LX1 and 2 (hereinafter, collectively referred to as linear bodies LX) are yarns, threads, and the like. Further, the linear body LX preferably has elasticity in its own radial direction.

The finger-passing ring 10 is provided with a finger-passing hole into which a finger can be inserted. The material for forming the finger-through ring 10 is preferably metal, plastic, or the like. The material for forming the surrounding member 20 is preferably an elastic material such as metal or plastic.

As shown in FIG. 3A, the surrounding member 20 includes a C-shaped surrounding main body portion 22, a through portion 24, and a shielding portion 26.

The enclosure main body 22 is formed so as to surround the movement path LK of the linear body LX set on the outside of the finger threading ring 10. It is preferable that the direction of the movement path LK in the surrounding main body 22 (the direction of the paper surface in FIG. 2) and the direction of the finger passing hole of the finger passing ring 10 (the lateral direction in FIG. 2) are in a twisted position relationship.

The through portion 24 is a gap formed by both ends of the C-shaped surrounding main body portion 22, and the width W24 of the gap is preferably such that the linear body LX can pass through. The through portion 24 allows the linear body LX to pass through the inside and outside of the surrounding main body portion 22.

A fixing portion 22F fixed to the finger passing ring 10 is formed on the surrounding main body portion 22. The fixed portion 22F is preferably located on the opposite side of the through portion 24 with respect to the blocking portion 26.

The blocking portion 26 is provided so as to block between the movement path LK and the passing portion 24. The blocking portion 26 is for preventing the linear body LX from falling off.

The blocking portion 26 extends from the first portion 22A (the end portion in FIG. 3A) of the surrounding main body portion 22 toward the second portion 22B (the middle portion in FIG. 3A). The base end portion of the blocking portion 26 is connected to the first portion 22A of the surrounding main body portion 22, and the tip end portion of the blocking portion 26 is close to the second portion 22B of the surrounding main body portion 22. In this way, a gap 28 is formed between the tip end portion of the blocking portion 26 and the second portion 22B of the surrounding main body portion 22 so that the linear body LX can pass through. The width W28 of the gap 28 is preferably narrower than the width W24 of the through portion 24.

When the linear body LX has elasticity in its own radial direction, the width W24 of the through portion 24 and the width W28 of the gap 28 are preferably slightly narrower than the diameter of the linear body LX. This makes it easier for the linear body LX to engage with the surrounding member 20 and makes it difficult for the linear body LX to fall off.

Further, in the usage state of the guide mechanism 2 (for example, FIG. 1), the height of the base end portion of the blocking portion 26 is the same as the height of the tip portion of the blocking portion 26 or a position lower than the tip portion of the blocking portion 26. Is preferable. The usage state of the guide mechanism 2 may be "a state in which the fixing portion 22F is located below". This makes it easier for the linear body LX to engage with the surrounding member 20 and makes it difficult for the linear body LX to fall off.

The through portion 24 is preferably closer to the base end portion of the shielding portion 26 than to the tip end portion of the shielding portion 26. This makes it easier for the linear body LX to engage with the surrounding member 20 and makes it difficult for the linear body LX to fall off.

It is preferable that a plurality of surrounding main body portions 22 are provided. Further, it is preferable that the plurality of surrounding members 20 are provided in the same direction.

Next, how to use the guide mechanism 2 will be described.

First, the index finger of the left hand is passed through the finger through hole of the finger through ring 10. Next, the linear body LX is passed through the through portion 24, and then the linear body LX is passed through the gap 28. As a result, the movement path LK of the linear body LX is as shown in FIG. 3 (a).

When knitting as shown in FIG. 1, the aggregate LS (for example, a yarn ball) of the linear body LX is located on one side of the linear body LX with reference to the guide mechanism 2, and the opposite side thereof. The tip of the linear body LX is located in (FIG. 4). Then, the linear body LX is woven from the tip end portion by the knitting rod AB.

During knitting, the linear body LX supplied from the aggregate LS is subjected to external tension. However, the amount of tension varies depending on the movement of the knitting rod AB, the feed of the linear body LX, the movement of the aggregate LS, and the like. Due to this change in tension, the linear body LX that was in the internal space of the surrounding member 20 may move to the outside, that is, fall off from the surrounding member.

The guide mechanism 2 of the present invention can be prevented from falling off by a blocking portion 26 provided so as to block between the moving path LK and the passing portion 24. Further, by making the shape and layout of the through portion 24 and the shielding portion 26 predetermined, it is possible to more reliably prevent the linear body LX from falling off.

The shape of the surrounding member 20 is not limited to that shown in FIG. 3A. For example, as shown in FIGS. 3 (b) to 3 (c), the width W24 of the through portion 24 may be wider than the diameter of the linear body LX. Further, as shown in FIG. 5, the blocking portion 26 may extend from the second portion 22B (midway portion) of the surrounding main body portion 22 toward the first portion 22A (end portion). Then, the through portion 24 may be closer to the tip end portion of the blocking portion 26 than to the base end portion of the shielding portion 26.

Next, a method of manufacturing the guide mechanism 2 will be described.

The method for manufacturing the guide mechanism 2 includes a finger-through ring forming step, a surrounding member forming step, and a fixing step.

In the finger-through ring forming step, the plate-shaped first material 51 (FIGS. 6A to 6B) is bent to form a finger-through ring 10 (FIG. 2) having a predetermined shape. Considering the bending process, the first material 51 is preferably a metal. For example, by using the first material 51 having a thickness of 0.5 mm to 2 mm, bending can be performed using pliers or the like. As a result, a C-shaped finger threading ring 10 is obtained (FIG. 2).

In the enclosing member forming step, the plate-shaped second material 52 (FIGS. 6C to 6d) is bent to form the enclosing member 20 having a predetermined shape. Considering the bending process, the second material 52 is preferably a metal. For example, by using the second material 52 having a thickness of 0.5 mm to 2 mm, bending processing can be performed using pliers or the like.

In the fixing step, the finger passing ring 10 obtained in the finger passing ring forming step and the surrounding member 20 obtained in the surrounding member forming step are fixed by using an adhesive. As the adhesive, any known adhesive may be used, and a reactive adhesive, a solution adhesive, a solid adhesive (hot melt), a dissolving adhesive, or the like may be used.

As shown in FIG. 6B, it is preferable that the second material 52 is uneven. As a result, unevenness is formed on the inner wall surface of the surrounding member 20. Due to this unevenness, it is possible to more reliably prevent the linear body LX from falling off.

Further, from the viewpoint of ease of manufacture, as shown in FIGS. 6A and 6C, the width (length in the Y direction) of the first material 51 and the second material 52 tends toward the end in the X direction. It is preferable to narrow it.

In the above embodiment, the base end portion of the blocking portion 26 extends from the surrounding main body portion 22, and the tip end portion of the blocking portion 26 is close to the surrounding main body portion 22, but the present invention is not limited to this. For example, even if two shielding portions 26 are provided, each base end portion extends from the surrounding main body portion 22, and a gap 28 is formed between the respective tip portions so that the linear body LX can pass through. good.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
