For some time, it has been provided with a band-shaped main body, and a locking portion including a through-hole formed so as to connect one side and the other side of both main surfaces of the main body with the support. There is known a band body which is locked to a support by being penetrated through the body (for example, see Patent Document 1).
Patent Literature 1 relates to a luggage fixing band with a hook (the column of “articles related to design” in Patent Literature 1), specifically, “a luggage fixing band having a hook at one end, preferably rubber. It is made of elastic material. The band body is provided with a plurality of holes for hanging on its own hook, a hook on another band, or a hook on a bed. The end of the band that is distal to the side on which the hook is provided is provided with a hole through which the hook and the band portion attached to the hook can pass. " Description of the article ") discloses a band.
The band body of the band disclosed in Patent Literature 1 (the luggage fixing band with a hook in Patent Literature 1) has a plurality of holes for hanging on hooks, and the band has a band-shaped main body. And a locking portion including a through-hole (in Patent Literature 1, “a plurality of holes for hooking”) formed to connect one side and the other side of both main surfaces of the main body. The supporting member (the hook in Patent Literature 1) penetrates the through hole (the hole in Patent Literature 1) to be locked to the supporting material.

Design Registration No. 1551219 (for example, article related to design, description of article related to design, front view, reference perspective view 2 showing use state, etc.)

The band disclosed in Patent Literature 1 (the luggage fixing band with a hook in Patent Literature 1) is provided with a through hole (hole) for hanging the support (hook) on the band main body. ) Can be locked to the support (hook) by penetrating the through hole (hole).
However, if the through-hole is made large with respect to the support so that the support can be easily penetrated into the through-hole, there is a problem that the strip easily falls off from the support. On the other hand, if the through-hole is formed small with respect to the support in order to make it difficult for the strip to fall off from the support, it may be difficult to make the support penetrate through the through-hole.
In view of the above, an object of the present invention is to provide a belt that can easily penetrate a support through a through hole and that is less likely to fall off the support from the support.

The band of the present invention (hereinafter, referred to as “main band”) includes a band-shaped main body and a through hole formed so as to connect one side and the other side of both main surfaces of the main body. A band which is locked to the support by allowing the support to penetrate through the through-hole, wherein the locking portion is formed around the through-hole and the periphery of the through-hole. And a thin portion formed at least in part and having a smaller thickness than the main body.
The belt includes a belt-shaped main body and a locking portion, and the locking portion includes a through hole. The through hole is formed so as to connect one side and the other side of both main surfaces of the main body. Then, a main body (for example, a hook) for supporting the main body is passed through the through-hole, so that the main body is locked to the support.
The locking portion of the belt body has the through hole and a thin portion formed at least partially around the through hole. The thin portion has a smaller thickness than the main body.
With this, when the support is penetrated through the through hole of the main body, the thin portion having a smaller thickness than the main body can be easily deformed, and the support can be easily penetrated into the through hole. The deformed thin portion abuts on the penetrated support (the thin portion abuts against the surface of the support by the deformation of the thin portion so as to press between the surface of the support and the thin portion). This causes friction and makes it difficult for the main belt to fall off the support.

In the main band, the through-hole may be a slit portion having a gap formed elongated along a slit direction which is a predetermined direction (hereinafter, the main band is referred to as "slit main band"). .).
By doing so, the slit portion having an elongated gap along a predetermined direction (slit direction) with respect to the main body constitutes the through-hole. , The support can be easily penetrated into the slit, and both edges of the slit defining the gap abut against the support penetrated through the slit, so that the surface of the support is And the two edges are surely frictioned with each other, so that the main body is less likely to fall off from the support.

In the main slit body, the support is penetrated through the gap of the slit portion, and when the band is displaced in the slit direction with respect to the support, the thickness is larger than the thin portion adjacent to the locking portion. The support may be in contact with the surface formed by the main body.
By doing so, when the support is penetrated through the gap of the slit portion and the main band is displaced in the slit direction with respect to the support (for example, by applying a force to the main band, The main body is displaced in the slit direction), and the support comes into contact with the surface formed by the main body (thicker than the thin portion) adjacent to the locking portion including the slit portion. For this reason, since the outer surface of the support comes into contact with the surface of the main body portion that is thicker than the thin portion, it is possible to prevent or reduce tearing or breakage as compared with contact with the surface that the thin portion has. Can be.

In the main slit body, the thin portion is defined by an edge defining the gap of the slit portion and a thin outer edge line which is a line connecting one end and the other end of the slit portion in the slit direction. (Hereinafter, referred to as “thin outer edge main body”).
Since a thin portion is formed in a region surrounded by an edge defining the gap of the slit and a thin outer edge line (a line connecting one end and the other end of the slit in the slit direction), A thin portion is formed along the edge defining the gap. For this reason, when penetrating the support through the slit portion, the thin portion can be easily deformed at any position along the slit direction to easily penetrate the support into the slit portion, and the thin portion is Friction is generated by contacting the support penetrated through the slit portion, and the main body is less likely to fall off the support.
It should be noted that the line referred to here includes not only a curve but also a line segment. For example, the line may include not only a curve but also a mixture of a curve portion and a line segment portion.

In the thin outer edge main band body, the thin portion may be formed as a pair by one and the other of both edges defining the gap of the slit portion.
By doing so, a thin portion is formed by one of the two edges defining the gap of the slit portion, and a thin portion is also formed by the other of the two edges defining the gap. When penetrating the support, the thin portion on one side and the thin portion on the other side are easily deformed at any position along the slit direction, so that the support is more easily formed on the slit portion. In addition to being able to penetrate, both the thin portion on the one side and the thin portion on the other side can come into contact with the support penetrated through the slit portion, so that the main body falls off the support. It becomes difficult.

In the thin outer edge line main body, the thin outer edge line has a smooth curved portion that is concave as viewed from the slit portion, in which a distance from the slit portion monotonically increases as the distance from the one end and / or the other end of the slit portion increases. (Hereinafter referred to as “monotonically increasing partial main body”).
The thin outer edge line has a curved portion having one end or the other end of the slit portion, and the curved portion forms a concave smooth (differentiable) curve when viewed from the slit portion. The distance between the curved portion and the slit portion monotonically increases as the distance from the end increases.
As described above, the thin outer edge line defining the boundary between the thin portion and the main body portion (thick portion) has the curved portion on one end side and / or the other end side of the slit portion. The main body (thicker than the thin portion) is formed adjacent to the locking portion including the slit by displacing the main body in the slit direction with respect to the support by penetrating the support. Even if the support comes into contact with the body, the stress is prevented from being concentrated on the part of the main body corresponding to the curved portion (the part that is easily subjected to the force from the support), and the main body is prevented from being torn or damaged. Or can be reduced.

In the monotonically increasing partial main body, all of the thin outer edge lines may be smooth.
By doing so, the thin outer edge line is smooth (differentiable) at any position of the thin outer edge line that defines the boundary between the thin portion and the main body (thick portion), so that the main body adjacent to the thin portion is It is possible to prevent stress from being concentrated on any part of the part, and to effectively prevent or reduce tearing or breakage of the main body part.

In the main slit body, the slit direction may be the same as the longitudinal direction of the main body.
This allows the support to penetrate through the gap of the slit portion, a force in the longitudinal direction of the main band is applied to the main band, and the main body is displaced in the slit direction with respect to the support. Since there is no displacement in the width direction of the band (perpendicular to the longitudinal direction of the band), even if the band is displaced in the slit direction, the band interferes with the surrounding objects. Prevent or reduce this and make the use of the main body convenient.

In the present belt body, at least one of both side edges of the main body along the longitudinal direction of the main body has a plurality of protruding portions projecting in a direction perpendicular to the longitudinal direction along the longitudinal direction. (Hereinafter, referred to as “projecting portion main body”).
In this way, when the user of the main body holds the main body by hand, the protruding portion can prevent or reduce the main body from slipping in the longitudinal direction of the main body (longitudinal direction). When the main body slides, the protruding portion is caught by the hand holding the main body.)

In the protruding portion main body, both side edges of the main body along the longitudinal direction have the protruding portions, and the positions of the protruding portions of the both side edges in the longitudinal direction coincide with each other. May be used.
With this configuration, since both side edges of the main body have the protruding portions so that the positions in the longitudinal direction coincide with each other, the main body can be more effectively prevented from slipping in the longitudinal direction of the main body. (When the main body slides in the longitudinal direction, both side edges at the same position in the longitudinal direction are simultaneously caught by the hand holding the main body.)

In the protruding portion main body, the outer edge of the protruding portion may be along a smooth curve from one end to the other end of the outer edge.
As described above, the main belt body slides in the longitudinal direction along a smooth (differentiable) curve (for example, an arc, an elliptic arc, a quadratic curve, a cubic curve, etc.) from one end to the other end of the outer edge of the protruding portion. Thus, when the protruding portion is caught on the hand holding the main body, a large impact is not applied to the hand, and it is possible to prevent or reduce pain or injury to the hand.

In the protruding portion main body, a locking portion may be formed corresponding to the position of the protruding portion along the longitudinal direction.
Since the locking portion has a through hole and a thin portion having a smaller thickness than the main body, the position along the longitudinal direction of the main body where the locking portion is formed is different from other portions. The strength (tensile strength in the longitudinal direction) may be lower than that in the above (in a cross section of a plane perpendicular to the longitudinal direction, the position of the locking portion is different from that of the cross-sectional area due to the through hole or the thin portion). Smaller than the position.) For this reason, by forming the locking portion corresponding to the position of the protruding portion along the longitudinal direction, the cross-sectional area is increased by the protruding portion, so that the cross-sectional area by the locking portion is supplemented and the strength reduction by the locking portion is prevented. Or can be reduced.

It is CC sectional drawing of FIG. It is an enlarged view of a hook fitting part. It is a figure showing how to use the baggage fixing belt.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited by these.

1 is a partially omitted plan view showing a luggage fixing belt (main belt) 11 according to one embodiment of the main body, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 1 is a cross-sectional view taken along the line BB (a cross-section along a slit 32 described later), FIG. 4 is a cross-sectional view taken along the line CC in FIG. 1, and FIG. 5 (a) shows the hook fitting portion 13 viewed from the front surface 37 side, and FIG. 5 (b) shows the hook fitting portion 13 viewed from the back surface 39 side.) The present belt 11 will be described with reference to FIGS. Here, in order to facilitate the description and understanding, three axes orthogonal to each other, that is, an X axis, a Y axis, and a Z axis are used, and the directions of these X axis, Y axis, and Z axis are indicated by arrows X and arrows This is shown as Y and arrow Z, respectively.
The belt 11 has a belt shape as a whole along the X-axis direction (longitudinal direction of the belt 11) (both front surfaces 37 and a back surface 39 are both perpendicular to the Z-axis). The whole is integrally formed of a flexible rubber (a material having excellent weather resistance that can withstand sunlight and rainwater).

The belt 11 includes a belt main body 12 that forms an elongated body in the X-axis direction, a plurality of hook fitting portions 13 formed on the belt main body 12 at predetermined intervals (here, about 80 mm) along the X-axis direction, Is provided. Each of the plurality of hook fitting portions 13 is formed to have the same structure, shape, and dimensions.
The hook fitting portion 13 is formed in the shape of a first straight column (one bottom surface and the front surface 37 belong to the same plane) from the front surface 37 side to the rear surface 39 side of the main belt 11. And the second straight column (one bottom surface and the rear surface 39 of the second straight column belong to the same plane) from the rear surface 39 side to the front surface 37 side of the main belt 11. , A thin portion 36 formed to partition the front side recess 14a and the rear side recess 14b, and a slit elongated along the X axis so as to divide the thin portion 36. 32. Here, the first straight column and the second straight column both have the same shape and dimensions, and when the thin portion 36, the first straight column, and the second straight column are combined, One straight pillar is formed (that is, the first straight pillar and the second straight pillar are formed at the same position in plan view). In particular, as shown in FIG. 5, the bottom surfaces of the first and second straight pillars (any one of the four bottom faces of both the bottom face of the first straight pillar and the bottom face of the second straight pillar) Is the same as above) is an arc connecting a pair of line segments F1 and F2 parallel to the X axis (the distance between the line segments F1 and F2 is about 10 mm) and one end of the line segment F1 and one end of the line segment F2. G1 (here, semicircle), and an arc G2 (here, semicircle) connecting the other end of the line segment F1 and the other end of the line segment F2. The arc G1 is divided into two portions, an arc portion G11 and an arc portion G12, at one end Q1 of the slit 32. Similarly, the arc G2 is divided at the other end Q2 of the slit 32 into two portions, an arc portion G21 and an arc portion G22. The thin portion 36 has a thickness J2 (dimension in the Z-axis direction) of about 1.5 mm, and is thinner than a thickness J3 between the front surface 37 and the back surface 39 of about 5 mm. The slit 32 is formed to be elongated along a straight line parallel to the X axis where the distance to the line segment F1 and the distance to the line segment F2 are equal (the gap J1 is about 1.5 mm, and the X axis of the slit 32 is The slit 32 divides the thin portion 36 almost symmetrically with respect to the straight line along which the slit 32 extends. The slit 32 is an opening that connects the front surface 37 side and the back surface 39 side of the main belt 11, and into which a hook (not shown) for locking the main belt 11 is fitted as described later.

  A hook (not shown) for locking the present belt 11 is fitted into the hook fitting portion 13, but the thin portion 36 is replaced with a thick portion (the belt body formed between the front surface 37 and the back surface 39). 12) Since it is thin and easily deformed as compared with 12), a hook (not shown) for locking the belt 11 is easily fitted into the slit 32, and a thin wall is formed on the surface of the hook (not shown) fitted in the slit 32. The abutment (entanglement) of the portion 36 and the occurrence of friction can prevent or reduce the inserted hook (not shown) from dropping out of the slit 32 unexpectedly. At both ends in the X-axis direction of the thin portion 36, a locking wall 38 formed by the thick portion is formed in a shape along the side surface of the right cylinder, and a hook (not shown) fitted into the slit 32 is provided. Even when the locking wall 38 is in contact with the locking wall 38, damage or deterioration of the locking wall 38 can be prevented or reduced by preventing or reducing stress concentration on the locking wall 38.

Have been.
Similarly, the side surface 35 includes a first side surface 35a along a second straight line parallel to the X axis and a second side surface 35b formed at predetermined intervals along the X axis direction and along an arc (convex outward). In any cross section (for example, FIGS. 2 and 4) of a plane perpendicular to the X axis, any part of the side surface 35 is formed in an arc shape (here, an arc having a radius of about 3 mm). It is rounded. Since the side surfaces 33 and 35 are rounded in a cross section of a plane perpendicular to the X axis in this manner, the belt 11 is gentle to the user's hand (not shown) of the belt 11, and this part is In addition to preventing or reducing the scratching or pain of the hand when hitting, the roundness can increase the contact area with the hand and improve the anti-slip effect.

The arc along the second side surface 33b, the arc along the second side surface 35b, the first straight line, and the second straight line exist on the same plane perpendicular to the Z axis. The second side surfaces 33b and 35b on both sides of the slit 32 in the Y-axis direction are such that the center of the arc along the second side surface 33b and the center of the arc along the second side surface 35b are on the X axis. The slit 32 and the thin portion 36 that the slit 32 divides are substantially plane-symmetric with respect to the one plane.
As described above, in the present belt 11, the first side surface 33a and the first side surface 35a are formed at the same position along the X axis, and the second side surface 33b and the second side surface 35b are formed at the same position along the X axis. And a thin portion (formed by the first side surface 33a and the first side surface 35a) and a thick portion (formed by the second side surface 33b and the second side surface 35b) are alternately formed as a whole. Have been. The length (the dimension in the X-axis direction), the thickness (the distance between the front surface 37 and the back surface 39), and the width (the dimension in the Y-axis direction) of the belt 11 can be appropriately determined according to the use and purpose. . Here, the width of the thin part is about 31 mm, and the width of the thick part is about 41 mm.

The front surface 37 is along a plane perpendicular to the Z axis, and the back surface 39 is along a plane perpendicular to the Z axis.
One end face 24 is formed on each of one end and the other end of the main belt 11. One end face 24 connects one end of the side face 33 and one end of the side face 35 (one end side of the main belt 11), and the other end of the side face 33. And the other end of the side surface 35 (the other end of the main belt 11). Each of the end faces 24 has a shape along a circular arc (outwardly convex; here, a substantially semicircular shape). The end face 24 has an arc shape (here, an arc having a radius of about 3 mm) in the cross section of any plane parallel to the Z axis in which the center of the arc along the end face 24 is present, as in the case of the side faces 33 and 35. It is attached.

FIG. 6 is a diagram showing a method of using the present belt 11. Specifically, FIG. 6 (a) shows that the present belt 11 is engaged with a hook 101 having a base end mounted near the bed of a truck (not shown). It is a side view which shows a state, FIG.6 (b) is EE sectional drawing of Fig.6 (a). With reference to FIG. 6, an engagement state of the belt 11 with the hook 101 will be described.
In FIG. 6, the tip 103 of the hook 101 is fitted into the slit 32 of the hook fitting portion 13 (here, the tip 103 penetrates from the back surface 39 side to the front surface 37 side), so that the present belt 11 is inserted into the hook 101. It is locked. Here, in FIG. 6A, a tension in the right direction (arrow K in FIG. 6) is applied to the main belt 11, and the hook 101 exists at the end of the slit 32 (the left end in FIG. 6B). The belt 11 is locked to the hook 101 by contacting the locking wall 38. Since the locking wall 38 is formed by a thick portion (belt body 12) in a shape along the side surface of the right cylinder, even if the hook 101 abuts on the locking wall 38, the stress concentration on the locking wall 38 can be reduced. By preventing or reducing the damage, it is possible to prevent or reduce the damage or deterioration of the locking wall 38. In addition, the hook 101 that has penetrated the slit 32 abuts the deformed portion 36d of the thin portion 36 that has been deformed by penetrating the hook 101, so that the friction between the deformed portion 36d and the surface of the hook 101 causes the hook 101 to move. It is possible to prevent or reduce a sudden drop from the slit 32 (especially, even when the tension on the main belt 11 is weakened or lost, it is possible to effectively prevent the main belt 11 from dropping from the hook 101. ).

Since the entire belt 11 is integrally formed of a flexible rubber, one of the hook fitting portions 13 on one end side of the present belt 11 is locked to the hook 101, and a truck carrier (not shown) is used. The luggage (not shown) loaded on the belt 11 is tied up by the belt 11, and the belt 11 is pulled while the belt 11 is stretched in the X-axis direction and tension is generated in the direction of contraction. By hooking any one of the hook insertion portions 13 existing on the other end side of the hook 101 to the hook 101, a tension in a contracting direction is generated between the hook insertion portions 13 to prevent the main belt 11 from falling off from the hooks 101. It can be effectively prevented.
Since the portion where the second side surfaces 33b and 35b are formed has a convex shape outward, when the user (not shown) grips the belt 11 by hand, The belt 11 is prevented from sliding along the X-axis direction (longitudinal direction), and has a larger cross-sectional area than the portion where the first side surfaces 33a and 35a are formed. Only contributes to the strength) to compensate for the strength drop.
