WO2018163268A1 - String with knobby portions - Google Patents

Abstract

In a conventional string with knobby portions, the diameters of the knob portions are substantially the same over the entire length of the string and therefore difficulty is involved when inserting all of the knobby portions into a string hole, as a large force is required and the task may cause pain in the fingers and hands. Moreover, if the string suddenly needs to be replaced, the installation requires time and effort to be expended. The present invention is characterized in that a string is provided with a plurality of elastically deformable knobby portions disposed at intervals in the axial direction, wherein the knobby portions are configured from two or more types of knobby portions having different diameters in a direction orthogonal to the axial direction of the string.

Description

A string with a hump

The present invention relates to a string having a plurality of spherical or spindle-shaped and elastically deformable humps spaced apart in the axial direction.

A string having such a hump has been conventionally known as a string that does not require a knot. Specifically, as shown in FIG. 1, it is composed of a hump part 0101 that can be elastically deformed by applying tension from the axial direction of the string, and an intermediate part 0102 that connects the hump parts. Two structures shown in Patent Documents 1 to 3 are mainstream.

FIG. 2 is a perspective view in which a string having a hump is applied to a shoelace. When used as a shoelace, the shoelace is inserted through a strap hole 0204 formed in the shoe 0205. In the natural state where no tension is applied to the string, the diameter of the hump is larger than the string hole, but when the string is pulled strongly, the hump is elastically deformed and penetrates the string hole. Since it is restored to its natural state and is caught in the string hole, the string is not loosened by the tightening condition. When putting on or taking off shoes, the entire shoe also elastically changes due to the elastic deformation of the hump, so there is no need to tie or loosen the strings one by one.

FIG. 3 shows an example in the case of using as the pants string 0303. Also in this case, like the case where it is used as a shoelace, the hump part 0301 is inserted through the string hole 0304 and used. Although not shown in the drawings, as other examples of the use of the string having the hump portion, a through hole is provided in the temple of the spectacles to be used as an anti-falling string for the spectacles, or in the helmet or hat. It is also possible to use it as a string for preventing falling out.

The conventional cords having the humps shown in Patent Documents 1 to 3 are each provided with a plurality of humps having the same shape with the same intervals 0202 and 0302, and tightening by adjusting the position of the humps. The condition is adjusted.

As for the string having the conventional hump part, the diameter of the hump (diameter in the direction perpendicular to the axial direction of the string) is all the same as described above, so the diameter of the hump part is too large for the string hole In order to insert all the strings, a large force is required, and there are cases where it is difficult to hurt fingers and hands or to take a long time for wearing. Also, it may take time and effort to urgently change the string.

The present invention is a string comprising a plurality of elastically deformable humps spaced in the axial direction in order to solve the above-described problems of the prior art, wherein the hump is orthogonal to the axial direction of the string. It is comprised from 2 or more types of hump parts from which the diameter of the direction to carry out differs.

According to the present invention having the above-described configuration, by appropriately arranging a large-diameter hump portion that gives a large resistance to the string hole and a medium / small-diameter hump portion that can relatively reduce the resistance force. , A part that can be inserted into the string hole without relatively applying force when wearing the string and a part that has a relatively high resistance to the string hole are born, and it hurts fingers and hands when wearing compared to conventional This can be reduced and the wearing time can be shortened.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to these embodiments at all, and can be implemented in various modes without departing from the scope of the invention.

First, based on FIG. 4, the definition of each component of a string having a hump according to the present invention is clarified. FIG. 4 shows the appearance of a natural state in which no external force is applied to the string. In FIG. 4, a1 indicates the diameter of the large-diameter hump, and a2 indicates the diameter of the small-diameter hump. Yes. The diameter is a diameter in a direction orthogonal to the axial direction (longitudinal direction) of the string. In the figure, b1 indicates the length of the large-diameter hump, b2 indicates the length of the small-diameter hump, and b and a are substantially equal when the hump is spherical, and b when it is spindle-shaped. > a. When tension is applied to the string from the longitudinal direction, a is elastically deformed so as to be reduced, and b is elastically deformed so as to be long. In the figure, c is an intermediate part (also referred to as an interval) formed between the hump parts, and FIG. D shows the diameter of the intermediate part. In addition, as described in Patent Documents 2 and 3 above, the intermediate portion hardly deforms elastically (does not expand) even when tension is applied to the string from the longitudinal direction. As described in FIG. 1, a structure that extends to some extent may be employed. Further, the structure of the hump portion itself may be the structure described in any of Patent Documents 1 to 3. In addition to the small-diameter hump, when a medium-diameter hump is adopted, the diameter is represented as a3 and the length is represented as b3. Based on the above, each embodiment of the present invention will be described.

FIG. 5 is a diagram schematically showing various strings (a) to (d) according to the first embodiment of the present invention. A horizontal line and a circle are the string 10, and a portion indicated by a circle indicates the hump portions 1, 2, and 3. The size of the circle expresses the diameter of the hump part. The largest circle is the large-diameter hump part 1, the smallest circle is the small-diameter hump part 2, and the middle circle is the medium-diameter hump part. 3. FIG. 5 schematically shows the arrangement (arrangement) of the humps having large, medium, and small diameters, and does not show the exact size and arrangement. Moreover, it is the figure which cut off and expressed not the whole string but the part.

As shown in FIGS. 5 (a) to 5 (d), the various cords according to the present embodiment have a plurality of hump portions spaced apart in the longitudinal direction, and the plurality of hump portions have a diameter. Are arranged by appropriately arranging different sizes of large, medium and small. As shown in the figure, the string (a) has a large diameter hump 1 and a small diameter hump 2 arranged alternately, and the strings (b) and (c) have a small diameter between the large diameter hump 1. A state in which two or three humps 2 are continuously arranged, the string (d) includes a large-diameter hump portion 1, a medium-diameter hump portion 3, a small-diameter hump portion 2, and a medium-diameter hump portion 3. The arrangement of the large-diameter humps 1 is continuous.
Further, as shown in FIG. 10, the hump portion according to the present invention is basically arranged symmetrically from the center of the string, but may be arranged asymmetrically in some cases.

When using the lace of this embodiment as a shoelace, the diameter of the lace hole of a sneaker or an athletic shoe is generally about 2 to 4 mm, so the size of each hump as a standard type is a small-diameter hump. The diameter a2 of the head part is about 4 to 5 mm, the diameter a3 of the medium diameter hump part is about 6 to 7 mm, and the diameter a1 of the large diameter hump part is 7 mm or more. You may do it. In that case, for example, for a shoelace having a small diameter of 2 mm, the diameter a2 of the small-diameter hump is about 3 mm, the diameter a3 of the medium-sized hump is about 4 mm, and the diameter a1 of the large hump is For shoelaces with a diameter of about 5 mm and a large lace hole diameter of 5 mm, the diameter a2 of the small-diameter hump is about 6 mm, the diameter a3 of the medium-sized hump is about 7 mm, and the diameter a1 of the large-diameter hump is It is about 8 mm. In the prior art, the diameter of the hump is about 7 mm and is the same. Note that the diameter d of the intermediate portion may also be changed according to the size of the string hole.

If the diameter of the hump part is different, the resistance when passing through the string hole changes. Specifically, the resistance when the large-diameter hump portion 1 is inserted into the string hole is relatively large (similar to that of the prior art), and conversely the small-diameter hump portion 2 and the medium-diameter hump portion 3. The resistance when inserting into the string hole is relatively small.

The difference in resistance described above due to the size of the diameter of the hump appears as a difference in the amount of force applied to the fingers and hands of the person who inserts the string into the string hole. The more this is done, the smaller the load on the user. Comparing the three types of the strings (a) to (c) shown in FIG. 5, the string (a) requires the greatest force for insertion, and the string (c) is attached to the shoe without requiring the most force. Is possible. On the contrary, it is the order of the string (c), the string (b), and the string (a) that is easily detached from the string hole by an external force after being attached.

For this reason, the string (a) is suitable as a string for sports and young people, and the string (c) is suitable as a string for elderly people who have weak fingers and hands and do not exercise vigorously.

The examples shown in FIGS. 5 (a) to 5 (d) are merely examples, and by arranging a plurality of humps having different diameters appropriately, various merits can be obtained according to the age and usage of the user. Can be obtained.

FIG. 6 schematically shows a modification of the first embodiment. Although FIG. 5 shows an arrangement in which the combined arrangement of the large diameter, medium diameter, and small diameter hump parts is repeated, the diameter of the hump parts may be changed within a large range of the entire string. In other words, in FIG. 6, five areas of “left end side area” 0602, “center area” 0601, “right end side area” 0603, “left central area” 0604, and “right central area” 0605 are deformed. Although shown, the diameter of the hump may be changed for each of these set areas.

As shown in FIG. 6, only the small-diameter hump 2 (or only the small-diameter and medium-diameter humps 2 and 3) is arranged in the central region, and the left-end side region and the right-end side region have a large diameter. Only the hump 1 may be arranged. In this case, the small-diameter hump portion 2 or the small-diameter and medium-diameter hump portions 2 and 3 are arranged near the tip of the shoe (toe side) of the shoelaces of the shoe. In this case, the large-diameter humps 1 are arranged. Since a large force is applied to the string hole on the foot insertion side, the large-diameter hump portion 1 has a strong resistance in the portion concerned, and conversely, a large force is not applied near the tip of the shoe. This is because it can sufficiently withstand the resistance force of the small-diameter or medium-diameter humps 2 and 3. By doing so, there is an advantage that the longest central region in the entire string can be very easily passed through the string hole. *

FIGS. 7A and 7B are diagrams schematically showing a second embodiment of the present invention. The second embodiment is different from the first embodiment described above in that the length of the interval between the hump portions is changed. In FIG. 7A, the interval between the large-diameter hump portions 1 and the interval between the small-diameter hump portions 2 are different, and the intervals indicated by “A1” in the drawing are all indicated by “A” in the drawing. It is the same as the interval, but is shorter than the interval indicated by “B” in the figure. This is because, in the small-diameter hump part 2 having a small resistance to the string hole, even if one hump part comes out from one string hole by shortening the interval between the hump parts and increasing the number of places where resistance occurs. This is because the next hump is immediately caught in the string hole, so that the fastening with the string does not change so much. On the other hand, in the case of the large-diameter hump 1, since the resistance against the string hole is large, even if the distance from the adjacent large-diameter hump 1 is separated, the hump does not come out of the string hole and is fastened. There is no difficulty. In the example of FIG. 7A, the large-diameter hump portion 1 is arranged at the center portion, the small-diameter hump portion 2 is arranged at both ends thereof, and the large-diameter hump portion 1 is arranged again at both end sides. The reason for this is to make it easier to position the center of the lace in the lace hole located at the tip of the shoe.

In FIG. 7 (b), the small-diameter humps 2 are arranged at narrow intervals “D” and “D1” at the center of the string, and the large-diameter humps 1 are arranged at wide intervals “C” at both ends. It is what I did. The basic design concept is the same as in FIG. 7 (a), but by arranging the three small-diameter humps 2 at short intervals, it is arranged so that it can be easily understood that the part is the center of the string. Yes.

It should be noted that the distance between adjacent humps is preferably about several mm to 30 mm, more preferably about 10 mm to 20 mm. The reason is that the narrower the interval between the hump parts, the easier it is to adjust the tightening degree, but conversely, the process of inserting into the string hole becomes complicated due to the increase in the number of hump parts. If the interval is within the above range, the insertion process into the string hole does not become complicated, and the flexible tightening condition can be adjusted.

FIG. 8 is a diagram schematically showing a third embodiment of the present invention. The basic arrangement and spacing of the humps are the same as in the first and second embodiments, but the total number of humps is an odd number, and the humps located at the center of the string are located on both sides of the humps. The feature is that it is different from the part.

In this embodiment, since the total number of the hump portions is an odd number, one hump portion is arranged at the center position of the string. By making this hump portion located at the center different from the hump portions located on both the left and right sides, it is utilized as a mark as a center position when the string is inserted into the string hole.

As shown in FIG. 8 (a), in order to make it easier for the user to recognize that the hump is located at the center of the string, a small-diameter hump 2 is arranged at the center of the string, and large on both sides thereof. As shown in FIG. 8B, the hump portion 1 having the diameter is arranged, and the hump portion 1 having the large diameter is arranged at the center and the hump portion 2 having the small diameter is arranged on both sides thereof. If the size is different, the center can be known by touch even when the shoelace is inserted in the dark, so that the center position of the strap can be easily grasped, and it can be worn symmetrically. Further, as another means for easily recognizing the center position, it may be possible to make any one of color, touch, rigidity, hump length, etc. different. In particular, in order to facilitate wearing at night, a fluorescent paint (phosphorescent paint) may be applied to the surface of the hump at the center position, or a reflective material may be applied. Further, the hump portion may be made of a fiber containing a fluorescent / luminescent material.

In the above-described embodiment, fluorescent paint or the like is applied only to the hump portion at the center position of the string so that the center position can be understood even at night. Over the entire length), a fluorescent paint (phosphorescent paint) may be applied, a reflective material may be applied, or a fiber containing a fluorescent / phosphorescent material may be used. In this case, since it is sufficient that the entire length of the string can be discriminated by phosphorescence or reflected light, it may be formed on a part of the surface, not on the entire surface. That is, if the string shines along the axial direction of the string, the entire string can be recognized even in the dark.

FIG. 9 is a diagram schematically showing a fourth embodiment of the present invention. The basic hump arrangement and spacing are the same as in the first and second embodiments, but the total number of humps is an even number, and the two humps located at the center of the string are both It is different from the humps on both sides.

In this embodiment, since the total number of the hump parts is an even number, unlike the case of the third embodiment, there is no hump part at the center of the string, and two hump parts are arranged on both sides of the center. . The center of the string when the string is inserted into the string hole is the above-mentioned second hump as a mark.

As shown in FIG. 9 (a), in order to make it easier for the user to recognize that the hump is in the central part of the string, two small-diameter hump parts 2 are arranged at the center of the string 10, A large-diameter hump 1 is arranged on both sides, or conversely, as shown in FIG. 9B, two large-diameter humps 1 are arranged in the center, and a small-diameter hump is placed on both sides. Part 2 is arranged. If the said structure is employ | adopted, it will become easy to insert a string through a string hole symmetrically also in various situations like 3rd embodiment. As another means for making the central hump different from the other humps, the color, the touch, the hardness, the length of the hump, etc. may be different as in the third embodiment. good.

In each of the above-described embodiments, the shape of the hump portion is described as a spherical shape, but the shape of the hump portion is not limited to a spherical shape, but a spindle shape, a cylindrical shape, or a polygonal column shape (triangular column, quadrangular column, pentagonal column, etc.) Or it may be an elliptical cone shape, or a combination thereof, and is not particularly limited as long as it is larger than the diameter of the string hole and has a resistance when inserted. Further, when the shape of the hump is a spindle shape, a columnar shape, a polygonal column shape, or a combination of an elliptical cone shape and a spherical hump, the length in the axial direction is 1. It is preferably about 5 to 5 times. Further, the entire string including the hump part and the intermediate part connecting the hump parts may be flat. In that case, the flat-shaped hump may be circular, spindle-shaped, quadrangular, elliptical, or a combination thereof in plan view.

As described above, according to the present invention, a hump portion (large-diameter hump portion) having a large resistance to the string hole and a hump portion (medium / small-diameter hump portion) capable of relatively reducing the resistance force. Are appropriately arranged, a part that can be inserted into the string hole without relatively applying force when the string is attached and a part that has a relatively large resistance to the string hole are created, compared to the conventional case. This can reduce the pain of fingers and hands during wearing and shorten the wearing time.
Further, if the configuration of the third and fourth embodiments is adopted, the user can easily set the center position of the string by making the protrusions located at the center of the string different from the protrusions positioned on both sides thereof. It becomes possible to recognize, and the mounting work can be performed quickly and easily.
