Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a one-touch tying device that automatically ties a finely woven part by threading a string around an item to be tied by simply grasping the operation handle attached to the handle. Such devices, such as the Japanese Patent Publication No. 55-48006, had the drawback of requiring skill in terms of maintenance and handling.

Although the present invention is manual, the mechanism is simple, so it is easy to handle even for people who are not familiar with machinery, and has successfully expanded its applications. To explain the present invention in more detail, it has been used in agricultural and horticultural work, such as kneading seedlings and splints together, tying grape vines in high places to shelves, and tying the ends of bags with string to hang fruit bags. There was a strong demand for a handy, simple and reliable device for tying medical instruments that do not allow the attachment of bacteria, that is, tying them using sterilized mechanical devices without manual intervention.
The present invention is convenient in that the string is tied in the process of gripping the operating handle with the hand and then releasing the gripped operating handle, and the knot can be tied into a single bow so that it can be easily untied later. It is. Next, to describe the basic means for achieving such an object, first, the binding of the present invention involves wrapping a string around the object B to be bound as shown in FIG. 9, and tying a knot at the end of the string. It is something that mechanically accomplishes what it creates. As shown in FIG. 3, as a preparatory work, strings were stretched across both ends of the semicircular guide at the front of the device, thereby greatly simplifying the device. The overall shape of the device of the present invention is shown in FIGS. 1 and 2, and the tip is bifurcated, and the rear lower part has a handle 2 and an operating handle 4. , the semicircular ring 7 loosely placed in the guide 5 rotates,
The right front part A presses the string wrapping piece 6' attached to the left end of the guide 5 together with the thread passed through the string passing hole 101 provided in the part, and the string wrapping piece 6' is attached to the left end of the guide Groove 4
Push it inside 5.

By the way, the thin winding piece 6' has a string end K' in advance.
Pinch it with your fingers and pull it out, and form a loop C on the thin wrapping piece 6' as shown in FIG.
Since this is fixed at the string ring 9, the front end A of the semicircular ring ends up entering the string ring C as shown in FIG. Continuing with the movement of the operating handle 4 (final stage),
The hook 29 of the L-shaped crochet hook 28 rises and hooks the string inside the string end K'. When the operating handle 4 is released in this step, the repulsive force of the springs 33 and 21 causes the hook 29 and the top A of the semicircular ring 7 to move back to their old positions, so that the binding is completed as shown in FIG. As shown in FIGS. 9 and 10, the string can be passed around the object B to tie it. An example of the present invention will be explained with reference to the drawings. In Figures 1 and 2, 1 is the machine base, 2 is the handle, and 4 is the operating handle that has a fulcrum 3 below the handle.By pulling this towards the handle 2, the device can be started with one hand. I can work. Reference numeral 5 denotes a guide which has a semicircular shape as a whole, and which itself is pipe-shaped or groove-shaped, and at one end (the left end in Fig. 1) there is a groove (referred to as guide opening □ groove) 45 at the entrance of the guide. A string end wrapping piece 6 that can be inserted into the inside is iron-coupled.

7 is a semicircular ring which is inserted into the groove of the semicircular guide and has a gear on the back side.

Reference numeral 8 denotes an elongated hole provided at the left end of the semicircular guide (Fig. 1), which penetrates from the upper surface to the lower surface in the figure.

9 is a hole for hooking the string end K' of the thin K, and 10 is a horizontal hole in the head of the semicircular ring (right side in Figure 1) to allow the thin K pulled out from the winding string to pass through. 10' is a groove provided so that the string can be easily passed through the string hole 10.

11 is the shaft of a small gear 12, and this small gear 12 meshes with the rear gear of the semicircular ring 7.

13 and 14 are bevel gears that cause the small gear 12 to move.

The bevel gear is fixed to the horizontal shaft 17, and 18 is an elongated hole provided in the machine base, and the chain wheel 19 provided in the innermost hole is also fixed to the shaft 1.
7, a spring 21 is attached to a pin 20 provided at the rear of the unit 1 as shown in FIG. 19. The end of the chain is attached to an axle pin 4' on the operating handle. 25 is a chain guide roll. On the other hand, a guide frame 26 is fixed to the front lower surface of the joint 1, and the mari pin 2
An L-shaped crochet needle 28 having a fulcrum at 7 is provided, and a hook 29 is vertical as shown and is inserted into and engaged with the elongated hole 8. That is, the tail part 30 of the needle is pivotally connected to the long pestle 32 by a pivot pin 30', 33 is a spring attached to the long mallet and lightly compressed, and 35 is installed at the end of the long mallet 32. The convex portion engages with the frame 36 provided at the top of the operating handle 4 when the operating handle is compressed, thereby operating the crochet hook.

Reference numeral 40 denotes the rotating shaft of the fine-winding bobbin 38, which is provided approximately in the center of the machine base, and 39 and 39' are guide bars with fine K.

Reference numerals 41 and 42 are thin green guides (FIG. 1), and K' indicates the end of the string that has passed through the string threading hole 10.

43 is a cutter, and 44 is a string gripping groove that assists the action of the cutter.

The operation of the device of the present invention having the above-described structure will be explained.

The action of this device is divided into a first stage and a second stage of operation when the operating handle is tightened, and when the handle is released, each mechanism attempts to return to its original position by the force of the spring. The operation will be explained as the third stage. First, pull out a small amount of the string end K' of the thin K from the string threading hole 10 as shown in FIG. From this prepared state, the string is pulled out by pinching the vertical end K' with fingers, and the end of the string is passed around the string end wrapping piece 6 as shown in FIG. In this case, the way to hang the string is as shown in the figure, with the end of the string tacking on the part where the string end wrapping piece is rolled up, and then the end of the string being hung on the lower string chicken implement. The string is thus stretched from the head A of the semicircular ring to the left of the guide. Next, as shown in FIG. 4, the object to be bound B' is moved forward while pressing the stretched string, and the object to be bound is placed inside the semi-circular guide. In this state, grip the handle 2 and the operating handle 4 with your hands. That is, when the operating handle 4 is pulled in the direction of the arrow around the three-point point 3, the chain 22 is pulled against the spring 21, causing the chain wheel 19 to rotate. Therefore, the bevel gear 1 on the same axis 17 as the wheel
4 rotates, and the bevel gear 13 that meshes with the bevel gear 13 and the pinion gear 12 coaxially attached rotate. Since the small gear 12 meshes with the rear gear of the semicircular ring 7, the semicircular ring eventually rotates in the direction of the arrow, and the head A of the ring touches the right end of the semicircular guide 5 as shown in FIG. The starting point reaches the string end wrapping piece 6 which is iron-coupled to the other end of the guide, and plunges into the hollow hole 6' of the piece 6 and presses it to close the guide entrance of the semicircular guide 5. Rotate until it is recessed into the groove 45. During this time, the string K is let out and entangled in the state shown in FIG. In other words, the head A of the semicircular ring enters into the string ring C formed on the string end wrapping piece, but the string theory is as shown in the diagrams (Figures 4 and 5). It does not move because it is blocked by the upper green, and only the string end winding piece sinks into the closing groove 45 of the guide, so that the string carried by the semicircular ring in the thread C is inserted into the string passing hole. 10
It is inserted while being folded in half. The above is considered to be the first stage operation. Next, when the operating handle 4 is further tightened and the frame 36 provided at its tip pushes the protrusion 35 at the rear of the Nagamura 32 to the right (Fig. 2), the Nagamura 32 Pushed to the right against the force of the spring 33, the crochet hook 28 is rotated upward about the fulcrum 27 via the upper pivot 30' of the tail 30 of the crochet hook 28, and the hook 2
Raise 9.

The hook thus enters the elongated hole 8 provided at the end of the semicircular guide, rises unhindered due to the recess 46 formed below the tip A of the semicircular ring, and passes through the chair hole; It reaches above the string end K' and is located in the center of the loop 47 formed at the rear of the thin through hole 10. Also, since the top of the hook 29 is round, like the crochet hook in stockinette knitting machines, when it goes up, it just touches the end of the cord K', but when it goes down, the cord is hooked on the hook (Figure 7). can be done. The above is the second stage operation. After this, by releasing the gripped operating handle 4, each mechanism attempts to return to its old position by the force of the spring, but at this time, the entangled strings are tied together as described above.

That is, in FIG. 7, the spring 33 is released from compression and the Nagamura 32 moves forward and pushes the tail 30 of the crochet hook 28, so the hook 29 descends as shown by the arrow and returns to its old position. The class end K' hooked onto this is drawn into the loop 47. Also, since the spring 21 is released from its stretched state and contracts, the chain 22 is carried in the opposite direction to that described above, causing the pinion gear 12 to rotate in the opposite direction via the bevel gears 14 and 13, thus causing the small gear to rotate in the opposite direction. Since the semicircular ring 7 that engages with the ring 7 also retreats to its old position (Fig. 8), the rings are tied tightly at this time, as shown in Fig. 9, and the binding is thus completed. This is the third stage operation. In addition, the 10th
As shown in the figure, when the binding is completed, the thin K is cut with a cutter 43 provided at the tip of the right protrusion of this device.

This involves momentarily swinging the head of the device strongly in the direction of the arrow, but the string is held in the narrow gripping groove 44 and cut properly, leaving a cut string end K'. This returns to the initial state as shown in Figure 1, so the end of the string can be pinched and pulled out to move on to the next tying operation, making continuous work convenient. The device of the present invention can use any kind of thread string, such as a tape-like string.

In this case, if necessary, it is only necessary to slightly widen the string passage hole or slightly deform the structure of the string chicken tool 9. In addition, the binding device of the present invention can tie strings with a single touch, and can bind objects that grow on the ground, regardless of their shape.
As long as it is small enough to fit inside the semicircular guide, it is extremely convenient because it can achieve its purpose and can be easily used even in fields or forests where power cannot be obtained.
