Japanese Patent Laid-Open No. 2006-095007 JP 2012-116551 A

  The binding band disclosed in Patent Document 1 and the binding tool disclosed in Patent Document 2 are used to bind a connection point between a soft tube and a hard tubular object into which an end portion is inserted and the end portion is narrowed. In this case, there is a problem that the binding force may be weaker than when binding other objects.

  The present invention is for solving the above-described problems. An object of the present invention is to increase the binding force when binding a connection portion between a soft tube and a hard tubular object into which an end portion is inserted and the end portion is narrowed.

  The present invention will be described with reference to the drawings. It should be noted that the reference numerals in the figure are used in this column in order to help understanding of the contents of the invention, and are not intended to limit the contents to the illustrated range.

  In order to achieve the above object, according to an aspect of the present invention, the binding band 20 includes a band portion 30 and a buckle portion 32. The buckle part 32 is provided at one end of the band part 30. The band part 30 has a flat body part 40 and a plurality of convex parts 42. The trunk portion 40 can extend linearly and bend to form a ring. The convex portion 42 is disposed on the surface of the trunk portion 40. The convex portions 42 are arranged so as to form a row along the direction in which the body portion 40 extends. The buckle part 32 includes a through-passage forming part 50 and a hooking part 52. The through passage forming unit 50 forms a band through passage 60. The band penetration path 60 has an inlet 70 and an outlet 72. The other end of the band part 30 penetrates from the inlet 70 to the outlet 72 of the band penetration path 60. The hook portion 52 is fixed to the band penetration path 60. When the other end of the band portion 30 enters from the inlet 70, the hook portion 52 is hooked on any of the plurality of convex portions 42. The band part 30 further has a constriction forming surface 44. The constriction forming surface 44 is disposed on the back surface of the body portion 40 as viewed from the surface of the body portion 40 in which the plurality of convex portions 42 are arranged. The constriction forming surface 44 forms an inner peripheral surface that constricts as it approaches the other end 82 from one end 80 of the ring formed by the body 40 when the body 40 is bent so as to form a ring. Extend.

  When the other end of the band part 30 penetrates from the inlet 70 to the outlet 72 of the band penetration path 60, the trunk part 40 of the band part 30 bends to form a ring. The constriction forming surface 44 forms an inner peripheral surface that constricts as it approaches the other end 82 from one end 80 of the ring formed by the body 40 when the body 40 is bent to form the ring. It extends like this. When the binding band 20 binds a connection point between a soft tube and a hard tubular object into which the end portion is inserted and the end portion is narrowed, the body portion 40 is narrowed as it is bent so as to form a ring. The inner peripheral surface formed by the ball forming surface 44 narrows as it approaches the other end 82 from one end 80 of the ring. Thereby, the inner peripheral surface becomes easier to follow along the end portion where the above-described hard tubular object is constricted than when the inner peripheral surface of the ring is not constricted. The binding band 20 is less likely to slide in the direction along the central axis of the hard tubular object described above than the case where the binding band 20 does not extend along the end of the hard tubular object described above. Become. When the binding band 20 becomes difficult to slide in the direction along the central axis of the hard tubular material described above, the ring formed by the body portion 40 of the band portion 30 when the other end of the band portion 30 is pulled is softened accordingly. And the connection part with the hard tubular object which the edge part was inserted in this and the edge part is narrowed can be tightened strongly. As a result, the binding band 20 according to the present invention can increase the binding force when binding a connection point between a soft tube and a hard tubular object whose end is inserted into the soft tube and whose end is narrowed.

  Moreover, it is desirable that the buckle portion 32 described above further includes an opposing protruding portion 54. The opposing protrusion 54 protrudes from the band through path 60 so as to face the hook portion 52. The opposing projecting portion 54 faces the constriction forming surface 44 when the other end of the band portion 30 enters from the inlet 70 and any one of the convex portions 42 is caught by the catching portion 52.

  When the other end of the band portion 30 enters from the inlet 70 and any one of the convex portions 42 is hooked on the hooking portion 52, when the opposing protruding portion 54 is constricted and faces the forming surface 44, nothing protrudes from the band through passage 60 Compared to the case, the movement of the constriction forming surface 44 is limited. Since the movement is limited, the possibility that the convex portion 42 that is hooked on the hook portion 52 due to the movement of the band portion 30 inside the band through path 60 is reduced from the hook portion 52 is reduced. Since the possibility becomes low, the binding band 20 can increase the binding force compared to the case where the convex portion 42 is easily detached from the hooking portion 52.

  Alternatively, it is desirable that the above-described hook portion 52 has the meshing portion 90 and the hinge function portion 92. The meshing portion 90 meshes with any of the plurality of convex portions 42 when the other end of the band portion 30 enters from the inlet 70. The hinge function part 92 can be bent. The hinge function part 92 connects the meshing part 90 to the band penetration path 60. In this case, it is desirable that the opposing protruding portion 54 has a band sandwiching portion. When the meshing portion 90 is engaged with any one of the convex portions 42, the band sandwiching portion sandwiches the band portion 30 together with the meshing portion 90.

  When the band sandwiching part sandwiches the band part 30 together with the meshing part 90, the band part 30 can be strongly restrained compared to the case where the band part 30 is not sandwiched. Since the band part 30 is restrained strongly, the binding band 20 can strengthen the binding force.

  Alternatively, it is desirable that the band sandwiching portion described above has the facing surface 100. The facing surface 100 expands along the constriction forming surface 44 of the band portion 30 when the meshing portion 90 meshes with any of the convex portions 42.

  If the band sandwiching portion has the facing surface 100, the area of the portion facing the constriction forming surface 44 becomes larger than in the case where the band sandwiching portion has no facing surface 100. As the area increases, the possibility of damaging the band portion 30 decreases. If the possibility of losing the band part 30 is reduced, the possibility of losing the band part 30 strongly is reduced.

  According to the present invention, it is possible to increase the binding force when binding a connection portion between a soft tube and a hard tubular object into which an end is inserted and the end is narrowed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[overall structure]
FIG. 1 is a plan view of a binding band 20 according to the present embodiment. FIG. 2 is a side view of the binding band 20 according to the present embodiment. Based on FIG. 1 and FIG. 2, the structure of the binding band 20 concerning this embodiment is demonstrated. The binding band 20 according to the present embodiment is used for binding the connection points described below. The connection location is a connection location between a soft tube and a hard tubular object whose end is inserted and narrowed. An example of a soft tube is a soft hose made of synthetic resin. In the present embodiment, the hard tubular object means an object that is harder than a soft tube and that is at least partially tubular. Examples of rigid tubular objects include pipe joints and metal pipes. A soft hose and pipe joint made of synthetic resin are well known. Therefore, the detailed configuration is not described here. The binding band 20 according to the present embodiment is made of synthetic resin. In the case of this embodiment, the binding band 20 includes a band part 30 and a buckle part 32. The band part 30 is for tightening the connection part mentioned above. The buckle part 32 is for preventing the tightening by the band part 30 from loosening. The buckle part 32 is provided at one end of the band part 30. In the present embodiment, the binding band 20 is integral.

[Band configuration]
FIG. 3 is a cross-sectional view of the ring when the band unit 30 according to the present embodiment forms a ring. Based on FIG. 1 thru | or FIG. 3, the structure of the band part 30 concerning this embodiment is demonstrated. The band part 30 according to the present embodiment includes a body part 40, a plurality of convex parts 42, and a constriction forming surface 44. The trunk 40 is flat. The trunk portion 40 can extend linearly and bend to form a ring. The trunk portion 40 supports a load applied to the band portion 30 when the band portion 30 tightens the connection portion described above. The convex portion 42 is disposed on the surface of the trunk portion 40. As shown in FIG. 1, the convex portions 42 are arranged to form a row along the direction in which the body portion 40 extends. In this embodiment, when the trunk | drum 40 extends linearly, the convex part 42 is extended along the virtual plane described below. The virtual plane expands in the direction in which the body 40 extends. The rows formed by the convex portions 42 are along the virtual plane. The constriction forming surface 44 is disposed on the back surface of the body portion 40 as viewed from the body portion 40 where the plurality of convex portions 42 are arranged. That is, the convex portion 42 and the constriction forming surface 44 are arranged on the front and back of the trunk portion 40. The narrowed surface 44 extends along the direction in which the body 40 extends when the body 40 extends in a straight line. In the case of the present embodiment, the constriction forming surface 44 is inclined with respect to a virtual plane along which the convex portion 42 is along. As a result, the constriction forming surface 44 extends to form the inner peripheral surface described next when the body 40 is bent to form a ring, as shown in FIG. The inner peripheral surface narrows as it approaches the other end 82 from one end 80 of the ring formed by the body 40.

[Buckle configuration]
FIG. 4 is an enlarged plan view of the buckle portion 32 according to the present embodiment. 5 is a cross-sectional view taken along the line AA in FIG. Based on FIG. 4 and FIG. 5, the structure of the buckle part 32 concerning this embodiment is demonstrated. The buckle part 32 includes a through-passage forming part 50, a hooking part 52, and an opposing protruding part 54. The through passage forming unit 50 forms a band through passage 60. In the case of this embodiment, the band penetration path 60 is linear. The band penetration path 60 has an inlet 70 and an outlet 72. The other end of the band part 30 penetrates from the inlet 70 to the outlet 72 of the band penetration path 60. The hook portion 52 is fixed to the band penetration path 60. When the other end of the band portion 30 enters from the inlet 70, the hook portion 52 is hooked on any of the plurality of convex portions 42. The opposing protrusion 54 protrudes from the band through path 60 so as to face the hook portion 52. The opposing projecting portion 54 faces the constriction forming surface 44 when the other end of the band portion 30 enters from the inlet 70 and any one of the convex portions 42 is caught by the catching portion 52.

  In the case of the present embodiment, the hooking portion 52 has a meshing portion 90 and a hinge function portion 92. The meshing portion 90 meshes with any of the plurality of convex portions 42 when the other end of the band portion 30 enters from the inlet 70. The hinge function part 92 can be bent. The hinge function part 92 connects the meshing part 90 to the band penetration path 60. By this connection, the hook portion 52 is fixed to the band through path 60.

  In the case of this embodiment, the opposing protrusion part 54 consists only of a band clamping part. When the meshing portion 90 is caused to mesh with any of the convex portions 42, the band sandwiching portion sandwiches the band portion 30 together with the meshing portion 90. The reason why the opposing protrusion 54 can sandwich the band 30 as a band sandwiching part is that the constriction forming surface 44 of the band 30 protrudes so as to be naturally pressed against the opposing protrusion 54 when the meshing part 90 is raised. It is. The phenomenon that the meshing portion 90 is caused occurs when the band portion 30 is pulled back toward the entrance 70 of the band through passage 60. The pulling back causes a meshing portion 90 that meshes with the convex portion 42. In the case of the present embodiment, the band sandwiching portion has a facing surface 100 and a band base portion 102. As shown in FIG. 4, the facing surface 100 is inclined with respect to the inner peripheral surface of the band penetration path 60. As a result, the facing surface 100 expands along the constriction forming surface 44 of the band portion 30 when the meshing portion 90 meshes with any of the convex portions 42. The band base portion 102 supports the facing surface 100 when the facing surface 100 receives a force from the band portion 30.

[Manufacturing method of binding band]
The manufacturing method of the binding band 20 according to this embodiment is the same as that of a known binding band. For example, the binding band 20 according to the present embodiment is manufactured by injection molding. A known method for manufacturing a binding band such as injection molding is well known. Therefore, detailed description thereof will not be repeated here.

[How to use the cable tie]
The binding band 20 according to the present embodiment is mainly used for binding a connection point between a soft tube and a hard tubular object whose end is inserted into the soft tube and whose end is narrowed. For this purpose, when the binding band 20 according to the present embodiment is used, the user first places a soft tube on the end of the hard tube so that the end of the hard tube is inserted into the end of the soft tube. Connecting. When the connection is completed, the user turns the band portion 30 of the binding band 20 according to the present embodiment around the outer periphery of the connection portion of the tubes. At that time, the user adjusts the direction of the band portion 30 so that the inner peripheral surface formed by the constriction forming surface 44 is along the surface of the end portion of the hard tubular object. When the band unit 30 is rotated, the user causes the other end of the band unit 30 to enter the band through path 60 of the buckle unit 32 connected to one end of the band unit 30. When the other end of the band part 30 enters the band penetration path 60, the user pulls the other end of the band part 30. Since the other end is pulled, the band part 30 binds the connection part mentioned above. Accordingly, the meshing portion 90 of the buckle portion 32 meshes with one of the convex portions 42 of the band portion 30. When the meshing portion 90 meshes with any one of the convex portions 42, the binding by the binding band 20 ends.

[Effects of the binding band according to this embodiment]
As described above, the binding band 20 according to the present embodiment has a strong binding force when binding a connection point between a soft tube and a hard tubular object into which the end portion is inserted and the end portion is narrowed. it can.

[Description of modification]
The embodiments disclosed herein are illustrative in all respects. The scope of the present invention is not limited based on the above-described embodiment. Of course, various design changes may be made without departing from the spirit of the present invention.

  For example, the form of the opposing protrusion 54 is not particularly limited. Therefore, the shape of the opposing protrusion 54 may be pointed, formed with a ridgeline, or formed with a curved surface. Of course, the facing surface 100 of the facing protrusion 54 may not be along the narrowed surface 44 of the band portion 30 when the meshing portion 90 meshes with any of the convex portions 42. When the meshing portion 90 meshes with any one of the convex portions 42, the opposing projecting portion 54 may not sandwich the convex portion 42 together with the meshing portion 90. The opposing protrusion 54 may simply narrow the gap between the narrowed surface 44 of the band 30 and the inner peripheral surface of the band through path 60. Of course, the opposing protrusion part 54 is not limited to what consists only of a band clamping part.

  Further, the form of the constriction forming surface 44 is not limited to that described above. For example, the constriction forming surface 44 may be constricted suddenly in a section close to one end 80 of the ring formed by the body 40 and gently constricted in a section close to the other end 82. On the contrary, the narrowing formation surface 44 may be gradually narrowed in a section close to one end 80 of the ring formed by the body 40 and suddenly narrowed in a section close to the other end 82. The constriction forming surface 44 may or may not have a smooth surface with irregularities that cannot be recognized by the human eye. For example, a small protrusion may be provided on the entire surface of the constriction forming surface 44.

  Moreover, the band penetration path 60 does not need to be linear. Further, the material of the binding band 20 is not limited to the synthetic resin.
