DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knot tying device which presses and fixes a knot of a first knot when a newspaper, a book, etc. are laid and tied with a string to prevent the string from being loosened. .

[0002]

2. Description of the Related Art Conventionally, newspapers, magazines, books, and the like have been required to be tightly tied with a string for the purpose of organizing, tidying, and collecting resources, but in many cases the string is loosened. The luggage cannot be moved with the string. The reason that the string intended to be tied is loosened is that the knot of the first knot cannot be held down by pulling the string as hard as possible, and the string is generally loose at the time of the second main knot.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to press and fix the first knot when binding a pile of newspapers, books and the like with a string to prevent the string from being loosened. There is a tight packing by doing so that the string is not loosened.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a string tying device which presses and fixes a knot of a first knot to prevent loosening of a string when tying newspapers, books, etc., one after another. A first aspect of the present invention is a string tying device including a tread plate and a string pressing portion provided on the back surface of the tread plate, wherein the width of the braid string pressing portion is sufficiently smaller than the width of the tread plate. The second invention comprises a lower step board and an upper step board movably provided so as to be able to repeat contact and detachment with the lower step board,
A string tying device including a string pressing portion having a width sufficiently smaller than the width of at least one of the upper and lower treads.

[0005]

2 (a) and 2 (c) are the simplest embodiments of the tying device according to the present invention.
(Shown in (b) and (d)), a stepping plate 1 and a string pressing portion 2 (3) on the back surface of the stepping plate 1, and the string pressing portion 2
The width of (3) is configured to be sufficiently smaller than the width of the footboard 1. The reason for this is that the string pressing portion 2 (3) is a portion that presses and fixes the knot of the first knot to prevent the string from being loosened.
This is for concentrating the power of the foot that is added to the body. The string pressing portion 2 is formed to be a convex portion on the back surface of the tread plate 1,
The string pressing portion 3 is formed on the back surface of the tread plate 1 so as to protrude outside the back surface shape of the tread plate 1. The string knot shown in FIG. 2C is easier to tie the string (because there is no obstacle on both sides of the gentle pressing portion), and as described in FIG. 4C, the knot of the first knot is pressed with the string. 2 (a), which is preferable to that shown in FIG. In FIG. 2 (d), FIG.
As shown in (a), when the string pressing portion 3 is formed as a convex portion on the back surface of the tread plate 1 (formed so as to be about 3 mm higher).
This is preferable because the force of the foot applied to the tread plate 1 can be concentrated. FIG.
In the embodiment of (b), the part 4 serving as a fulcrum where the string pressing part 3 can press the string or move away from the string by placing the foot on the step board 1 and shifting the weight in FIG. This corresponds to the one formed on the back surface. Therefore, FIG.
As shown in (c), when the foot is put on the treadle 1 and the weight is moved backward, the string pressing portion 3 is separated from the string (lifts), and when the weight is moved forward, the string can be strongly pressed. In this case, the portion 4 serving as a fulcrum is step-shaped, but may be a protrusion as shown in FIG. If the rear portion of the step board 1 is formed smoothly as shown by the two-dot chain line, the foot can be easily put on. Here, how to use the tying device of FIG. 3B will be described.

That is, as shown in FIG. 4A, a newspaper, a book or the like is superimposed on the string 5 to perform the first knot, and the string pressing portion 3 is matched with the first knot as shown in FIG. As described above, the footboard 1 is moved between both hands while narrowing. Subsequently, FIG.
While placing the foot on the treadle 1 as shown in (c) (weight is hung rearward and the string pressing part 3 is floated by the fulcrum 4), both ends of the string are pulled up so as to sandwich the string pressing part 3, The knot of the knot is surely matched so as to be directly below the string pressing portion 3. Then, as shown in FIG. 4D, both ends of the string 5 are strongly pulled and tightened. At the next moment, the weight is shifted forward, and the knot of the first knot is strongly pressed and fixed by the string pressing portion 3, and the ring 6 for the second knot, ie, the final knot is pressed with the string as shown in FIG. Make it in front of part 3 (make it as small a ring as possible), and then pull on both ends of string 5 at a stretch to complete the fore knot (at this time, if you slightly release the power of your feet, you can tie it smoothly ). In order to quickly and smoothly complete the final knot in FIG. 4 (e), as shown in FIG. 3 (e), the leading end of the string pressing portion 3 forms an obtuse angle θ with the string pressing surface 3 ′, and It is good to form so that it may extend to the upper surface of. This is because the ring 6 is tied along the slope at the time of final knotting (because it becomes slippery). In this sense, it is preferable that the angle θ between the tip of the string pressing portion 3 and the string pressing surface 3 ′ is large, but there is a dislike that the length of the string pressing portion 3 increases, and therefore, as shown in FIG. The problem can be solved if the angle formed by the string pressing surface 3 'at the tip of the string pressing portion 3 is particularly large near the string pressing surface 3'. As apparent from FIG. 4 (e), it is considered that the string is loosened due to the size of the ring 6 until the ring 6 is completely tied at the time of the main knot (slightly). In order to avoid this, it is desirable to make the ring 6 smaller, that is, to make the width of the string pressing portion 3 as small as possible, but there is a possibility that strength and rigidity are insufficient. The solution is to form the width of the string pressing portion 3 so as to be small near the string pressing surface 3 'and to be large near the upper surface of the string knot as shown in FIG. The reinforcement ribs 7 are formed between the middle of the height of the part 3 and the upper surface of the string knot. In order to reinforce the force for pressing and fixing the knot of the first knot in FIG. 4D, it is desirable to form a non-slip irregularity on the string pressing portion 3 as shown in FIG. FIG. 3 (N) shows a case in which a blade 8 for cutting a string is provided at a predetermined position of the string knot, so that work can be performed without separately preparing scissors, a cutter, or the like. The hole 9 is for storing a string tying device on a hook. FIG. 3 (L) shows a screen-like wall 10 (about 2 cm in height) formed at the edge of the tread plate 1, and the tread plate 1 is freely moved by the operation of the foot. You can match the knot of the first knot. For the same purpose, a projection 10 '(about 2 cm in height) may be formed between fingers as shown by a two-point line,
As shown in FIG. 3 (ヲ), the foot plate may be provided with a foot hook portion 11. Note that the embodiments shown in FIG. 3 can be combined with each other to increase the effect.

Next, a string knot according to the present invention shown in FIG. 5 (a) is composed of a lower tread plate 13 and an upper tread plate 12 movably provided so as to be able to repeatedly contact and detach from the lower tread plate 13. At least one of the upper tread plate 12 and the lower tread plate 13 is provided with a string pressing portion 14 having a width sufficiently smaller than the width thereof. FIGS. 5 (b) and 5 (c) show views of the string tying device viewed from above and from the side, respectively. The string pressing portion 14 is the upper step board 1
2 is formed so as to be a convex portion on the back surface, and is formed only on the upper tread plate 12. However, even if it is formed only on the lower tread plate 13, it is formed on both the upper tread plate 12 and the lower tread plate 13. It may be formed. The string knot is made of, for example, a synthetic resin (polycarbonate or the like), and swings when the upper tread plate 12 is stepped on with a foot, and the knot of the first knot is pressed and fixed by the string pressing portion 14 as described in FIG. You can do it. In this case, as shown in FIG. 6 (a), the upper step plate 12 and the lower step plate 13 are separately provided, and both are connected by a swing shaft 17 having a torsion spring.
2 may perform a rocking motion. Also, FIG.
The upper stepping plate 12 may be movably provided so as to be able to repeat contact and detachment with the lower stepping plate 13 by using the guide pin 18 having a spring as a guide. 5B and 5C, another embodiment of the string pressing portion 14, that is, the string pressing portion 14 is formed on the back surface of the tread plate 12 (upper step plate) so as to protrude outside the back surface shape of the tread plate 12. An embodiment corresponding to this is shown in FIG. Reference numeral 15 denotes a string pressing portion formed as described above. In FIG. 5D, the lower tread plate 13 is used.
FIG. 5 (e) shows an embodiment corresponding to one in which a guide portion 16 for guiding a string is formed. In this case, the guide portion 16 has a groove shape, and the central portion in the longitudinal direction is higher as shown in the figure.
When the string is pulled left and right in the state shown in FIG. 4D, the first knot is automatically moved to the raised portion. Since the guide portion 16 is provided, there is an advantage that the knot of the first knot and the string pressing portion 15 can be easily matched. Of course, in this case, the guide portion 16 may not be in the shape of a groove but may be in the form of a simple step as shown in FIG. In FIG. 5E, FIG.
In order to strengthen the force for pressing and fixing the knot of the first knot as in (d), it is desirable to form irregularities that serve as a non-slip. (It is good to mesh with each other). As a representative example, the use of the tying device of FIG. 5 (e) will be described.
In (a), the string 5 is connected to the upper tread plate 12 and the lower tread plate 13.
, That is, put in the guide part 16 and perform the first knot,
As shown in FIG. 4D, both ends of the string 5 are strongly pulled. Subsequently, a weight is applied to the upper step board 12 and the foot is strongly stepped on (by the time the upper step board 12 is lightly stepped so as to float), and the knot of the first knot is pressed and fixed. Then, the final knot is completed as shown in FIG. If the rear part is lifted with the front part of the tie as a fulcrum, the tie can be removed from the string. Note that the respective embodiments of FIG. 3 may be applied to the tying device of FIG.
(F) etc.). The string knot of FIG. 5 has a stronger force than the string knot of FIG. There is an advantage that the string comes down on the book or the like and the string sinks and slips easily), and the guide part 16 makes it easy to match the knot of the first knot with the string pressing part 15. The string knot which is considered to be the best in the string knot shown in FIGS. 2 and 3 is shown in FIG. 1 (a), and the string knot shown in FIGS. The tying device is shown in FIG. In each case, the string pressing portions 3 and 15 are formed so as to protrude outside the back surface of the tread plates 1 and 12, and an angle between the string pressing portions 3 and 15 and the string pressing surface is formed near the string pressing surface. And each is formed so as to be particularly large. Reference numeral 19 denotes a string matching mark (formed as a protrusion or a concave portion or a colored line), which is used to bring the string and the string pressing portion 3 into the most suitable position. Reference numeral 20 denotes a stopper which prevents the upper tread plate 12 from being bent more than necessary. Reference numeral 21 denotes a leaf spring, which gives a function of improving the return of the upper step plate 12.
