A string is attached to the end of the lever connecting portion 3a. A through handle 3 is fixedly provided. The string passing handle 3 is perpendicular to the handle 13. By pulling in the direction, the recoil shaft 15 rotates and the flexible rod feeding wheel 6 is driven. It will be done. Also, when the operator releases the string threading handle 3, the feeding mechanism 2 Due to the unwinding force of the recoil spring in 4, the lever connecting part 3a and the string passing handle 3 is rewound.

[0009] Further, as described later, the engagement piece 3b at the tip of the string threading handle 3 is connected to the string threading release lever. By locking with the locking portion 16b of the arm 16, the string brake device and the slack removal rod are connected. 7 is configured to be moved to the state where the string is threaded. Rotation of flexible rod feeding wheel 6 By rotating the string, the flexible rod 4 is let out. On the circumference of the flexible rod feeding wheel 6 A guide roller 8 is arranged close to the flexible rod feeding wheel 6 and the guide roller 8. Both of the drawer rollers 8 engage the string passing flexible rod 4 and draw it out.

0010 In this embodiment, the string passing flexible rod 4 has a screw protrusion wound around the outer periphery of the wire. The screw protrusion is equipped with a gear-shaped flexible rod. The teeth of the ejection wheel 6 mesh with each other to allow the ejector to be ejected. storage pie The rod 2 is divided into front and rear parts at the engagement part with the flexible rod feeding wheel 6, and the rear storage part is divided into two parts. The storage pipe 2b communicates with the handle 13, and is stored in the pipe of the handle 13. The handle 13 serves to guide the flexible rod 4 through which the string can be threaded. Its role is to store the flexible rod 4. The front storage pipe 2a has a binding string M and a string locking protrusion. The setting groove 2c for setting with 5 is configured in the shape of a notched groove.

[0011] The set state of the binding string M when threading the string is configured as shown in Figure 2. Ru. A string locking protrusion 5 fixed at the tip of the flexible string threading rod 4 allows the string threading flexible rod 4 to In the state unwound by the unwinding mechanism 24, as shown in FIG. It is stored at the rear of the set groove 2c. A string guide plate 23 is arranged at the front end of the support plate 14. The string guide plate 23 allows the string to be pulled out from the binding string tube A of the string case 32. The binding string M is guided through the guide hole 23a of the string guide plate 23, It is inserted into the guide pipe 1. The guide hole 23a is for hooking a string. An arc-shaped guide surface is provided in the pull-out direction to prevent

0012 Before the binding string M is passed through the string hole 18a of the needle 18, it is connected to the string brake device. 10 and slack removal rod 7, this operation also involves pulling the string passing handle 3. It is configured so that it can be done automatically by stretching it. That is, the guide of the string guide plate 23 A string brake device 10 and a brake roller 12 are installed at the position immediately before exiting the door hole 23a. It is arranged in a pressed state by a brake spring 19, and the string brake device 10 and the brake are placed in a pressed state. Frictional braking force is applied when the binding string M is pressed by the key roller 12. It is. 20 is a braking force adjustment handle for the braking spring 19.

[0013] Next, the configuration of the slack removal rod 7 will be explained. Slack removal rod 7 is a binding string M Lock the front and rear ends of the In this configuration, the guide pipe 1 is connected to the rear guide pipe. 1b and the front guide pipe 1a, and remove the slack of the binding string M from the divided part. It is taken out in the direction of 7. Therefore, the slack removing rod 7 is connected to the guide pipe 1. It is necessary to place the ring part at a position farther away than the slack removal rod 7. However, it is difficult to pass the string through the flexible rod 4 in the normal slack-removal state. Therefore, when threading the string, place the slack-removal rod 7 concentrically with the guide pipe 1. It is necessary to

[0014] Further, the string-passing flexible rod 4 and the string locking protrusion 5 at its tip are connected to the string brake device 10. It is necessary to pass between the brake rollers 12, but in the braking state Since it is impossible to pass through the cord, there is a device for releasing the cord brake device 10 when threading the cord. It is set up. At the same time as the string brake device 10 is released, the slack When threading the handle 7, a rotating device is placed in a concentric position with the guide pipe 1. -ing That is, as shown in the drawings of FIGS. 5 and 6, the string release arm 16 plays this role. The string release arm 16 pivots on the recoil shaft 15. The lace threading release arm 16 is operated by the lace threading handle 3. This is the joint piece 3b.

[0015] The operator sets the binding string M in the setting groove 2c, and then pulls the string threading handle. 3 to the side of the aircraft, this operation causes the end of the string handle 3 to The engaging piece 3b locks the locking portion 16b at the tip of the string release arm 16 and rotates. It is. A fulcrum crossing spring 16a is interposed in the string release arm 16, The engaging piece 3b holds the cord in the rotated position where the string is passed through. and After threading the string, the string threading handle 3 is returned to its original position by the feeding mechanism 24. However, when the string passing handle 3 is returned to its original position, the engaging piece 3b engages with the locking part again. 16b, and returns the string release arm 16 against the fulcrum crossing spring 16a. , the string brake device 10 is in the braking position, and the slack-taking rod 7 is in the slack-taking position. It is.

[0016] That is, the string release arm 16 rotates, and the pin 17a engaged with the arm 16 is released. The set arm 17 is rotated through it. Set arm 17 is a brake lock. is fixed to the brake roller shaft 22 of the brake roller 12, and the brake roller shaft A brake release cam 21 is fixed to the upper end of the brake release cam 22. is moved by the rotation of the set arm 17, and the string brake device 1 whose lower end is pivotally supported is moved by the rotation of the set arm 17. The upper end of 0 is opened. Then, the brake release cam 21 releases the string brake device. The string locking protrusion 5 and the string passing flexible rod 4 can pass through the open space 10. Ru.

[0017] At the same time, the coiled spring part that constitutes the base of the slack-removing rod 7 is attached to the brake roller shaft 22. The slack-removing rod 7 is rotated by the rotation of the set arm 17 as shown in FIG. Thus, it is rotated to a position concentric with the guide pipe 1. The set arm 17 times Due to the movement, the slack-removing rod 7 supported by a coiled spring is placed concentrically with the guide pipe 1. To avoid over-positioning, the slack-removing rod stopper 11 It is arranged on the side of the guide pipe 1 opposite to the rod 7.

[0018] With this configuration, when threading the string, first operate the string threading handle 3 to thread the string. The set arm is linked to the string release arm 16 by rotating the release arm 16. 17 to put the string through it as shown in Figure 3, and insert the binding string into the setting groove 2c in Figure 2. With M set, pull the string threading handle 3 to release the string threading flexible rod. 4 and the string locking protrusion 5 were pushed out from the storage pipe 2, and the binding string M was hooked on the tip. In this state, the cord brake device 10 in the open position is passed through, and the cord brake device 10 in the open position is passed through. It passes through the water collecting rod 7.

[0019] Furthermore, it is guided through the guide pipe 1 and exits in a direction approximately perpendicular to the tip of the needle 18. Then, the flexible rod 4 is protruded by the stopper 4a at the position where the string passes through the string hole 18a. The state is something that stops. The operator inserts the binding string that has passed through the string hole 18a. Take out the M and hook it into the state shown in Figure 4 to set it. In Figure 4, the conclusion A plan view of the bundling device part is shown, and the binding string M is fixed to the right end of the knotting frame 27. The positioning piece 25 is locked to accurately determine the position, and the end is the ejection rod 29 in the stored state. It is secured by hooking it onto a locking piece 26 provided on the arm.

[0020] In this state, pull the binding clutch door 28 to engage the clutch, and perform binding operation in the empty state. When the needle 18 is used, the knotted string M is inserted into the knotted bit in the knotted frame 27. Guide the binding cord M to the knot holder 30 and the knot holder 31, and hold it in the knot holder 31. It creates a state. After that, the end of the binding cord M cut by the cord cutting blade is released. Since it is pulled in by the rotation of the rod 29, the string can be removed by removing it from the locking piece 26. This completes the running process. 33 is a packer.

[0021] Next, the structure of the feeding mechanism 24 will be explained with reference to FIGS. 5 and 6. Support plate 1 4 is fixedly installed on the handle 13, and a feeding mechanism 24 is arranged inside. There is. The feeding mechanism 24 is a wire pulley that winds up the lever connecting portion 3a. 24a, and when the string passing handle 3 placed inside it is pulled, it is wound up and energy is released. When the string passing handle 3 is released, the lever connection part 3a is Composed of a recoil spring 24b that winds the wire around the wire pulley 24a. has been done. The wire pulley 24a is fixed to the recoil shaft 15, and The outer end of the spring 24b is fixed to the wire pulley 24a, and the inner end is fixed to the wire pulley 24a. It is permanently installed in some parts.

[0022] The recoil shaft 15 and the flexible rod feeding wheel 6 are not directly connected; A locking pin 15a provided at the upper end of the recoil shaft 15 is connected to the bolt of the flexible rod feeding wheel 6. They are interlocked via an operating differential gap 6a provided at the base portion. The operating differential gap 6 By providing a, the flexible rod can be unrolled immediately after pulling the string passing handle 3. The ring body 6 does not rotate, and therefore the flexible string passing rod 4 does not protrude. Locking pin 15 Only after a slightly rotates and comes into contact with the operating differential gap 6a, the flexible rod feeding wheel 6 rotates, causing the flexible rod 4 to pass through the string to protrude. Therefore, at the time of the operation difference, the string The threading release arm 16 rotates at the same time as the string threading handle 3 is pulled, so when the threading release arm 16 is set The string brake device 10 is released via the arm 17, and the slack-removal rod 7 is attached to the guide pipe. This provides room for arranging it concentrically with pool 1.

[0023] The support plate 14 of the lace threading device of the present invention is fixed on the right frame of the handle 13. There is. The flexible rod feeding wheel 6 on the support plate 14 allows the protruding and retracting. The string-passing flexible rod 4 has a long front end that extends beyond the needle 18 when extended. When storing, the tip position is inside the front storage pipe 2a, and the rear end is large. It needs to be stored all the way to the rear. Insert the string passing flexible rod 4 in the stored state. If a separate pipe is provided for the storage pipe, it will be quite long, so in this configuration, the storage pipe is The handle 13 also serves as a handle.

[0024] The handle 13 has traditionally been constructed by bending pipe material. The inside is hollow, so even if you store the flexible rod 4, it will get in the way. There is no such thing. In this configuration, the rear storage pipe 2b is provided and the flexible rod It guides between the wheel body 6 and the handle 13, but the rear storage pipe 2b Even if there is no handle, the flexible rod 4 may be stored directly inside the handle 13. Ru.

That is, First, the storage pipe 2 for the flexible rod 4, which requires a considerable length, is installed on the string guide plate. 23, the storage pipe 2 can be placed in a position where it does not get in the way. It became possible to do so.

[0026] Second, the binding string M coming out from the string guide plate 23 and the string coming out from the storage pipe 2. It is necessary to lock the flexible rod 4 with the string locking protrusion 5, but the storage pipe By arranging the loop 2 and the flexible string 4, the confluence of the two can be arranged easily. It became possible to do so.

[0027] Thirdly, with the string-passing flexible rod 4 stored inside the storage pipe 2, the string-passing flexible rod 4 is stored inside the storage pipe 2. By positioning the string locking protrusion 5 at the tip of the rod 4 at the rear of the string guide plate 23, The binding string M pulled out from the string guide plate 23 is locked to the front surface of the string locking protrusion 5 in the protruding direction. This allows for easy placement.
