Hereinafter, typical embodiments of the present invention will be described based on FIGS. 1 to 45D. The band device according to this embodiment is typically used as a substitute for a band-like body such as a tape or a string-like body such as a cord that is attached to various articles to provide desired functions. .

For example, such a band device may include (1) the band that is combined with a buckle to form a band device, and (2) a drawstring or tightening string provided on the clothing for squeezing the opening of the clothing or tightening a portion of the clothing. , (3) Shoelaces, (4) Back straps used in bags such as rucksacks, tape used in various straps, etc. (5) Shoe openings, bag openings, parts of the human body, etc. It is a substitute for bands used to narrow down the area.

Such a band device includes a band 1, a looping element 2, and a holding element 3 (see, for example, FIGS. 2 to 4). Alternatively, such a band 1 device comprises a band 1 and an attachment element 4 (see, for example, FIGS. 17 to 19). Alternatively, such a band 1 device comprises a band 1 and a retaining element 3 (see, for example, FIGS. 38 to 41). Alternatively, such a band device includes a band 1, a looping element 2, a holding element 3, and an attachment element 4 (see, for example, FIGS. 5 to 11). A band device may be constructed by combining one band 1 with two or more hanging elements 2, holding elements 3, or attachment elements 4.

The band 1 has a convex portion 1a along the width direction x (see FIG. 1) on at least one side, and a concave portion 1b along the width direction x between adjacent convex portions 1a. A plurality of them are provided in the direction y (see FIG. 1), and at least a portion of the one surface serves as the engagement surface portion 1c.

In the illustrated example, the band 1 includes a plurality of convex portions 1a and a plurality of concave portions 1b on one side thereof over its entire length, and the entire one side serves as the engagement surface portion 1c. Note that the engagement surface portion 1c may not be formed on the entire one surface. In some cases, the engagement surface portions 1c may be formed on both sides of the band 1.

In the illustrated example, equal intervals are formed between adjacent convex portions 1a at any position in the length direction y of the band 1, and at any position in the length direction y of the band 1, an equal interval is formed between adjacent convex portions 1a. Equal intervals are formed between the matching recesses 1b. One concave portion 1b is formed between adjacent convex portions 1a, and one convex portion 1a is formed between adjacent concave portions 1b. In the illustrated example, the convex portion 1a has a ridge shape along the width direction x of the band 1. The recess 1b has a groove shape along the width direction x of the band 1. In a cross section along the length direction y of the band 1, the engagement surface portion 1c has a waveform in which both the top side of the convex portion 1a and the bottom side of the recessed portion 1b are arcuate.

As will be described later, the band 1 is looped around the looping element 2 (described later) or a part of the attachment target of the band device, and one side of the band 1 is extended from the looping part of the looping element 2 or the attachment target. When the portion 1d and the other extending portion 1d are overlapped with the engaging surface portions 1c facing each other, each of the portions constituting the engaging surface portion 1c of the one extending portion 1d is overlapped at the overlapping portion 1e of both extending portions 1d. The convex portions 1a are complementary to each other in the recesses 1b constituting the engagement surface portion 1c of the other extension portion 1d, and each of the convex portions 1a is fitted into each recess portion 1b constituting the engagement surface portion 1c of the other extension portion 1d. The convex portions 1a forming the engagement surface portion 1c of the extending portion 1d can be fitted in a complementary manner.

Alternatively, when the band 1 is folded in half and overlapped so that the engaging surface portions 1c face each other, each of the convex portions 1a forming one of the engaging surface portions 1c in the overlapping portion 1e (see FIG. 3, for example) are complementary to each of the recesses 1b constituting the other of the engagement surface portions 1c, and each of the recesses 1b constituting the other of the engagement surface portions 1c has the recesses 1b constituting the other of the engagement surface portions 1c. The convex portions 1a can be fitted in a complementary manner.

In this embodiment, one convex portion 1a of the engagement surface portion 1c folded in half and superimposed in this way fits into the other concave portion 1b, and one convex portion 1b of the engagement surface portion 1c fits in the other recess 1b. The engaged state of the two engaging surfaces 1c containing the other convex portion 1a can be maintained by a holding element 3 or an attached element 4, which will be described later. As a result, the center of curvature z of the band 1 curved by being wrapped around the looping element 2, or the center of curvature z of the band 1 curved by folding in half, is changed to the length of the band 1. It is possible to reliably prevent a situation in which the center of curvature z is shifted to another location due to deviation in the width direction y. It becomes possible to stably maintain the state that has been changed or maintained.

The band 1 has bendable flexibility as described above. Band 1 is typically made of synthetic resin. When the band 1 is folded in half as described above, the folded part 1f (for example, see FIG. 8), that is, the curvature center z side, should be made slightly larger than twice the thickness of the band 1. It has become.
45A to 45D show some variations of Band 1. Also in the modified examples shown in FIGS. 45A to 45D, the convex portion 1a is formed along the width direction x of the band 1, and the recessed portion 1b has a groove shape along the width direction x of the band 1. Also in FIGS. 45A to 45D, the convex portion 1a and the concave portion 1b have complementary shapes. In the cross section along the length direction y of the band 1, in the modification shown in FIG. 45A, the projection 1a has a rectangular shape, in the modification shown in FIG. 45B, the projection 1a has a triangular shape, and in the modification shown in FIG. In the modification shown, a circular head is integrally formed on the neck, and in the modification shown in FIG. 45D, it is in an inverted trapezoid shape. In the modification of the form shown in FIGS. 45A and 45B, it is easy to disengage the engagement surfaces 1c. On the other hand, in the configuration shown in FIGS. 45C and 45D, since the convex portion 1a has a jaw portion, the engagement between the engaging surface portions 1c can be strengthened.

The holding element 3 and the attached element 4 allow the band 1 to pass through the overlapping portion 1e, and at the same time, the holding element 3 and the attached element 4 pass through the overlapping portion 1e of the band 1, and one side (extension A contact portion 6 that contacts the outer surface 1g (the surface opposite to the side that contacts the other side of the band 1) of one side of the protruding portion 1d or one side across the folded part 1f of the band 1 folded in half; The outer surface 1g (contacting the other side of the band 1) of the other side of the band 1 (the other side of the extending portion 1d, or the other side across the folded part 1f of the band 1 folded in half) constituting the overlapping portion 1e. and a contact portion 6 in contact with the mating side and the opposite side. The holding element 3 and the attachment element 4 prevent the overlapped portion 1e from coming apart between the two contact portions 6, and maintain the engaged state of the overlapped portion 1e.

In the following first to fourth examples, sixth examples, seventh examples, ninth examples, and tenth examples, the band 1 is placed on the terminal side of the passage portion 5 of the holding element 3 and the attachment element 4. It is designed to be passed from On the other hand, in the fifth and eighth examples, the overlapping portion 1e of the band 1 is inserted into the passage point 5 from the side perpendicular to the length direction y of the band 1, that is, along the length direction y of the band 1. It is designed to be introduced from one side edge 1h side.

(First example)
2 to 4 show an example of a band device configured to include a band 1, a hanging element 2, and a holding element 3. In this first example, the hanging element 2 and the holding element 3 are integrated into one member.

In this first example, a base 7 having a pair of sidewalls 9 formed on one side of a substrate 8 is provided with two shafts 10 spaced apart in the direction in which the sidewalls 9 are continuous. In the illustrated example, the shaft portion 10 located on the left side in FIGS. 2 to 4 among these two shaft portions 10 functions as the hanging element 2. A small hole 8a is formed in the base plate 8, which is used for sewing the base 7 to an article provided with the band device.

A shaft portion 10 constituting the hanging element 2 is constructed between a pair of side wall portions 9. The band 1 is introduced between the pair of side walls 9 from the right side in FIGS. 2 to 4, and after being wrapped around the hanging element 2, is pulled out again from the right side in FIGS. 2 to 4.

The holding element 3 is constituted by a lever 11 supported by the base 7 so as to be movable up and down. On the right side in FIGS. 2 to 4, the lever 11 is rotatably supported at one end with respect to the base 7 by a shaft portion 10 that is constructed between a pair of side wall portions 9. The supported portion 12 of the lever 11 is located next to the hanging element 2, and in the illustrated example, when the lever 11 is laid down, the portion between the supported portion 12 and the free end is located next to the hanging element 2. It is located on the upper side (see Figure 3).

The lever 11 has a part on the one end side, that is, a part of the outer surface of the portion 12 that receives support from the shaft portion 10 against the base 7 in a direction around the shaft portion 10, which is the center of rotation of the lever 11. , a first surface 13 and a second surface 14 having different distances from the shaft portion 10. The first surface 13 is formed along the arc of an imaginary circle (not shown) centered on the shaft portion 10 . The second surface 14 is located closer to the center of the virtual circle than the arc of the virtual circle. The lever 11 is placed in a prone position in which an imaginary straight line L1 connecting the other end, that is, the free end, and the shaft portion 10 is substantially parallel to the substrate portion 8 of the base 7 (see FIG. 3); It is rotatably combined with the base 7 between an upright position (see FIG. 4) where the straight line L1 intersects the substrate portion 8 of the base 7 at a predetermined angle. When the lever 11 is in the prone position, the first surface 13 faces one surface 15 of the base plate 8 with a gap therebetween, and when the lever 11 is in the upright position, the second surface 14 faces the base plate 8. 7 are arranged to face each other with a gap between one surface 15 of the substrate section 8.

The distance between the first surface 13 and one surface 15 of the substrate portion 8 of the base 7 when the lever 11 is in the prone position is substantially equal to twice the thickness of the band 1. .

Accordingly, in this first example, the lever 11 can pass through the extending portion 1d of the band 1 between the one surface 15 of the substrate portion 8 of the base 7 and the supported portion 12 of the lever 11. They are assembled with a gap left between them, and the gap narrows when the lever 11 is in the prone position.

Therefore, in this first example, when the lever 11 is in an upright state, the band 1 can be hung around the hanging element 2 by using the passage point 5 between the portion 12 supported by the lever 11 and the base 7. . In addition, the engagement state between the engagement surface portion 1c of one extension portion 1d of the band 1 which is hung around the hanging element 2 and extended, and the engagement surface portion 1c of the other extension portion 1d is as follows. By laying down the lever 11, it can be stably maintained.

FIG. 29 shows an example in which a band device is used in place of shoelaces. The holding element 3 of the first example is attached to one side of the shoe S, and the band 1 whose one end side is fixed to the other side of the shoe passes through the upper part of the shoe S and becomes integrated with the holding element 3. It is then hung around the hanging element 2, passed under the lever 11, and pulled out to the upper side of the shoe S again. In the figure, reference numeral 50 indicates a handle formed at one end of the band 1, and reference numeral 51 indicates a loop body through which the band 1 is passed in an overlapping state on the handle 50 side.

(Second example)
5 to 11 show an example of a band device configured to include a band 1, a hanging element 2, a holding element 3, and an attached element 4. In this second example, the hanging element 2 and the holding element 3 are separate from the attached element 4, and these three are linked via the band 1.

The hanging element 2 is located on the left side in FIGS. 5 and 6, the attachment element 4 is located on the right side, and the holding element 3 is located in the middle. Changing the length of one extending portion 1d (the upper extending portion 1d in FIG. 6) of the band 1 that is hung around the hanging element 2 and pulled out from the hanging element 2 to the right side in FIGS. 5 and 6. , the distance between the hanging element 2 and the attached element 4 can be changed, and thereby the part of the article to which the hanging element 2 and the attached element 4 are respectively fixed is located between the two fixing positions. It becomes possible to tighten or loosen.

In this second example, the hanging element 2 includes a shaft part 17 installed between a pair of side plate parts 16 disposed at an interval equal to or larger than the dimension in the width direction x of the band 1; The fixing portion 18 is constructed between the shaft portion 17 and a fixing portion 18 that is constructed between a pair of side plate portions 16 with an interval equal to the thickness of the band 1 (see FIGS. 5 and 7). . As shown in FIG. 5, a small hole 19 is formed in the fixing portion 18, which is used for sewing the fixing portion 18 to an article provided with the band device. In the illustrated example, the band 1 is passed between the shaft portion 17 and the fixing portion 18 from the lower side in FIG. The band 1 can be hung around the shaft portion 17 so as to be positioned on the other extending portion 1d of the band 1 located on the lower side.

In addition, in this second example, as shown in FIG. 8, the attached element 4 is able to pass through the overlapping portion 1e of the band 1 which is folded in half so that the engaging surface portions 1c face each other and are overlapped. The structure includes a passage portion 20 as the passage portion 5 that is configured to be unable to pass through the folded portion 1f. In the illustrated example, the attachment element 4 has a passage component portion 22 disposed on one surface of the fixing portion 21 at an interval that allows passage through the overlapping portion 1e and prevents passage through the folded portion 1f. The structure is as follows. As shown in FIG. 5, the fixing portion 21 and the passage portion forming portion 22 are connected by a pair of side plate portions 23. As shown in FIG. A space is provided between the pair of side plate parts 23 that is equal to or larger than the dimension of the band 1 in the width direction x. A small hole 24 is formed in the fixing portion 21, which is used for sewing the fixing portion 21 to an article provided with the band device. In the illustrated example, after passing the band 1 through the passage section 20 from the left side of FIG. 20 can be introduced to a position where the folded portion 1f is caught in the entrance 25 on the right side of the passage section 20. As a result, the attachment element 4 can be attached to the band 1, and the engagement state between one engagement surface portion 1c and the other engagement surface portion 1c in the overlapping portion 1e can be stably maintained by the passage portion 20. can be done.

That is, the distance between one surface of the fixing portion 21 constituting the passage portion 20 and the passage portion constituting portion 22 is substantially equal to twice the thickness of the band 1.

Further, in this second example, as shown in FIG. 9, the holding element 3 is constituted by a lever 27 supported by a base 26 so as to be movable up and down. The lever 27 is rotatably supported at one end with respect to the base 26 by a shaft portion 29 that is installed on a pair of side walls 28 formed on one side of the base 26 .

As shown in FIG. 11, the lever 27 rotates around the shaft portion 29, which is the center of rotation of the lever 27, on the one end side, that is, the outer surface of the portion 27a that receives support from the shaft portion 29 relative to the base 26. A part of the outer surface in the direction is composed of a first surface 30 and a second surface 31 having different distances from the shaft portion 29. The first surface 30 is formed along the arc of an imaginary circle (not shown) centered on the shaft portion 29 . The second surface 31 is located closer to the center of the virtual circle than the arc of the virtual circle. The lever 27 can be placed in a prone position where an imaginary straight line L1 connecting the other end, that is, the free end, and the shaft section is substantially parallel to one surface of the base 26, and in a prone position where the straight line L1 is parallel to one surface of the base 26. It is combined with the base 26 so as to be rotatable between an upright position intersecting one surface at a predetermined angle. Also, as shown in FIG. 10, when the lever 27 is in the prone position, the first surface 30 faces one surface of the base 26 with a gap, and as shown in FIG. 11, the lever 27 is in the upright position. At some point, the second surface 31 faces one surface of the base 26 with a gap therebetween.

The distance between the first surface 30 and one surface of the base 26 when the lever 27 is in the down position is substantially equal to twice the thickness of the band 1.

Accordingly, in this second example, the lever 27 is assembled with a gap formed between one surface of the base 26 and the supported portion 27a of the lever 27 through which the extending portion 1d of the band 1 can pass. At the same time, the gap becomes narrower when the lever 27 is in the prone position.

Therefore, in this second example, the lever 27 is erected on the other extending portion 1d of the band 1 that passes between one surface of the base 26 and the portion 27a that receives the support of the lever 27 as the passage point 5. In this state, one extended portion 1d of the band 1 can be passed through. In addition, the engagement state between the engagement surface portion 1c of one extension portion 1d of the band 1 superimposed vertically and the engagement surface portion 1c of the other extension portion 1d can be controlled by using a lever. By laying down 27, it can be maintained stably.

In addition, in this second example, a passage part 32 through which the end of one extending part 1d passes is formed at a position on the right side in FIG. The passage portion 32 is configured to be able to pass through the overlapped portion 1e of the band 1 folded in half and overlapped, but not to be able to pass through the folded portion 1f. As a result, in this second example, after the end side of the band 1 that has passed between the lever 27 and the base 26 of the holding element 3 is passed through the passage part 32 from the left side in FIG. 10, this end side is folded in half. to form the overlapping portion 1e, and this overlapping portion 1e can be introduced into the passage portion 32 from the right side in FIG. 10 to a position where the folded portion 1f is caught in the right entrance of the passage portion 32.

(Third example)
12 to 16 show an example of a band device configured to include a band 1, a hanging element 2, a holding element 3, and an attached element 4. In this third example, the hanging element 2, the holding element 3, and the attached element 4 are separate bodies, and the three are connected via the band 1.

The hanging element 2 and attached element 4 in this third example are substantially the same as the hanging element 2 and attached element 4 according to the second example, so the drawing showing the second example is in the drawing showing the third example. The same reference numerals as those given to the rotating element 2 and the attached element 4 are given in , and the explanation of the rotating element 2 and the attached element 4 will be omitted.

As shown in FIG. 16, the holding element 3 in the third example has a flat cylindrical shape with both ends open. That is, the holding element 3 has a configuration including a pair of wide surface portions 33 and a pair of narrow surface portions 34.

The distance between the inner surfaces of the pair of wide surfaces 33 in the holding element 3 is substantially equal to twice the thickness of the band 1, as shown in FIG. Further, the distance between the inner surfaces of the pair of narrow surfaces 34 in the holding element 3 is equal to or larger than the dimension of the band 1 in the width direction x.

As a result, in this third example, firstly, an overlapping portion consisting of one and the other extending portions 1d of the band 1 that is wrapped around the looping element 2 of the band 1 and extends from the looping element 2; 1e, it is movable along the length direction y of the band 1 with only the other extension part 1d (lower extension part 1d in FIG. 14) passing inside. The band 1 can be provided with a retaining element 3. Secondly, by moving the holding element 3 provided in this manner along the length direction y of the band 1, the overlapping portion 1e can be introduced into the holding element 3. Thereby, the engagement state of the overlapping portion 1e can be stably maintained by the holding element 3.

In this third example, a stopper 35 is provided on the other extending portion 1d between the holding element 3 and the attachment element 4 (see FIGS. 12 to 14).

Further, the distance between the inner surfaces of the pair of narrow surfaces 61 in the holding element 3 is equal to or larger than the dimension of the band 1 in the width direction x.

Accordingly, in this ninth example, firstly, an overlapping portion 1e consisting of one and the other extending portions 1d of the band 1 that is wrapped around a part of the object to which the band is attached and extends from this part. The band is movable along the length direction y of the band 1 with only the other extension part 1d (the lower extension part 1d in FIG. 39) passing through the center of the band 1. 1 can be provided with a holding element 3. Secondly, by moving the holding element 3 provided in this manner along the length direction y of the band 1, the overlapping portion 1e can be introduced into the holding element 3. Thereby, the engagement state of the overlapping portion 1e can be stably maintained by the holding element 3.

In this ninth example, a stopper protrusion 64 is provided on one cylindrical end side of the holding element 3. In the illustrated example, on the cylindrical end side of the holding element 3 facing toward the center of the band 1, there is a front side extension part 62 that continues from one wide surface part 60 and extends to the center side, and a front side extension part 62 that continues from the other wide surface part 60 to the center side. A rear extension part 63 extending to the side is formed, and the other extension part 1d (the lower extension part in FIG. A stopper protrusion 64 is formed to fit into the recess 1b constituting the engagement surface 1c of the portion 1d). The stopper protrusion 64 has a rib shape that continues along the width direction x of the band 1. The distance between the stopper protrusion 64 of the front extension 62 and the rear extension 63 is substantially equal to the thickness of the band 1 at the point where the recess 1b is formed, and the distance is substantially equal to the thickness of the band 1 in the longitudinal direction y of the band 1 of the holding element 3. Movement along the front side extension portion 62 is permitted by elastic deformation of the front extension portion 62. Accordingly, in this ninth example, when the overlapping portion 1e is introduced into the holding element 3, the stopper protrusion 64 of the front extension 62 applies a force that is less than the force that causes the elastic deformation. This prevents the holding element from moving toward the center of the band 1 when the band 1 is actuated.
