Description

The present invention relates to a band clamp that attaches, for example, a corrugated wire sheathed to a wire harness or the like routed to a vehicle at a predetermined attachment point of the vehicle.

For example, when a wire harness is installed in a vehicle, a tubular corrugated tube having annular irregularities continuous in the axial direction is sometimes used as the exterior material of the wire harness. A band clamp is used as a jig for fixing this corrugate to a vehicle-side mounting panel or the like at predetermined intervals.

The required diameter of the wire harness may vary depending on the connection destination (electronic equipment, battery, etc.) and the specifications of the vehicle body, and accordingly, the corrugated material used as the exterior material also has a different diameter. Therefore, it is desirable that the band clamp be one that can be used commonly for corrugates of multiple diameters.

For example, Patent Document 1 describes a band clamp that can be used for corrugates of multiple diameters, and a buckle that can be used to fix a band part that wraps around the outer periphery of a corrugate and a band part that is wrapped around a corrugate in stages with different wrapping amounts. A band clamp is disclosed having a section. According to the band clamp disclosed in Patent Document 1, since the band portion can be fixed with a wrapping amount depending on the diameter of the corrugate, it is said that it can be commonly used for corrugates of a plurality of different diameters.

However, corrugates are generally made of a flexible material such as resin so that they can be bent, expanded and contracted. In addition, in the band clamp, which can fix the band portion in stages with different winding amounts due to its flexibility, when a band gun is used, excessive force is applied when pulling the band portion and tightening the corrugate. Over-tightening may occur. In that case, the band portion is fixed with an excessive amount of wrapping relative to the diameter of the corrugate, which may cause unintended deformation of the corrugate.

Therefore, with the band clamp, it is not possible to use a band gun to attach it to the corrugate, and it is necessary to manually secure the band part wrapped around the corrugate with the buckle part after tightening it with an appropriate tightening force. . Then, in the work of attaching the band clamp to the corrugated gate, the worker has to be conscious of the degree of tightening of the band portion, making it impossible to further improve the efficiency of the work.

Japanese Patent Application Publication No. 2012-29484

In view of the above-mentioned problems, the present invention aims to provide a band clamp that can be easily and efficiently attached to a corrugated gate.

The present invention is a band clamp comprising a corrugate holding part that holds a corrugate, and a vehicle mounting part that is attached to a predetermined mounting location in a vehicle, wherein the corrugate holding part includes a band part that is wrapped around the outer periphery of the corrugate. , a buckle part that fixes the band part in a state wrapped around the corrugate, and a regulating part that comes into contact with the buckle part to regulate the amount of wrapping of the band part, and the regulating part that controls the wrapping amount of the band part. A plurality of attached parts are provided to which the regulating part is attached at positions, and the regulating part is attached to the attached part from the outer circumferential side of the band part in a wrapped state wrapped around the corrugate; and a contact part that contacts the buckle part.

According to the present invention, by attaching the regulating part to the fitted part corresponding to the diameter of the corrugate to be fixed, when tightening the corrugate by pulling the band part, it is possible to The contact portion can be brought into contact with the buckle portion at a position where the amount of winding is appropriate. As a result, the operator can easily know the position where the band part has an appropriate amount of wrapping, and the operator does not have to pay special attention to the tightening condition of the band part when attaching the band clamp to the corrugate. You can easily perform the work without having to pay anything.

Furthermore, since the contact portion contacts the buckle portion at a position where the amount of wrapping is appropriate, it is also possible to prevent the band portion from being pulled beyond the position where the amount of wrapping is appropriate. Thereby, in the work of attaching the band clamp to the corrugate, it is possible to suppress excessive tightening of the corrugate by the band portion when tightening the corrugate by pulling the band portion. Therefore, in the work of attaching the band clamp to the corrugated gate, the tightening work can be performed using a band gun instead of manual work.

As described above, according to the present invention, in order to fix the band part with an appropriate amount of wrapping according to the diameter of the corrugate during the installation work on the corrugate, the operator has to be particularly conscious of the tightening condition of the band part. Tightening work using a band gun can also be performed without having to pay any damage and without having to do it manually.
Therefore, the work of attaching the band clamp to the corrugate can be done easily and efficiently.

As an aspect of the present invention, the contact portion may be formed in a wedge shape that is inserted between the band portion and the buckle portion in the wrapped state.
According to this invention, it is possible to effectively suppress the displacement of the abutment part with respect to the buckle part, and the work of attaching the band clamp to the corrugate can be performed more easily and efficiently.

For example, if the abutting part that is in contact with the buckle becomes misaligned with the buckle due to some reason such as excessive force being applied during work, the diameter of the corrugate Therefore, it becomes difficult to fix the band portion at a position where an appropriate amount of wrapping is achieved. On the other hand, when the abutting part abuts the buckle part, the abutting part is inserted between the band part and the buckle part, so the position of the abutting part with respect to the buckle part is Misalignment can be effectively suppressed. Therefore, according to the present invention, the work of attaching the band clamp to the corrugate can be performed more easily and efficiently.

Further, as an aspect of the present invention, an axial convex portion that extends in the longitudinal direction of the band portion and can be fitted into the recess of the corrugate may be provided on the inner surface of the band portion that is radially inner in the wrapped state. good.
If the corrugate is misaligned with respect to the band clamp after the corrugated wire harness is routed to a vehicle, various problems may occur. Since it fits into the band clamp, it is possible to suppress misalignment of the corrugated gate with respect to the band clamp.

Extending in the above-mentioned axial direction is not necessarily limited to extending in a solid line shape, but also includes a plurality of axial protrusions connected intermittently in the axial direction, such as in a dotted line shape.

The above-mentioned "fitting in" does not mean only that the axial protrusion fits into the space formed by the recess of the corrugate without a gap. Allowing for some gaps to occur, the positional relationship between the axial protrusion and the recess of the corrugate is such that at least after the axial protrusion is received in the recess of the corrugate, the corrugate is relative to the band clamp. When a force in the direction of lateral displacement acts on either the corrugate or the band clamp, the axial convex portion abuts against one wall surface of the recess of the corrugate, thereby suppressing the lateral displacement. It's okay.

Further, as an aspect of the present invention, the mounted portion may be configured with a through hole that penetrates the band portion in the thickness direction, and the mounting portion may be configured with an insertion mounting portion that is inserted through the through hole.
According to the present invention, the restriction part can be mounted by a simple operation of inserting the insertion mounting part into the predetermined through hole, so that the work can be made easier and more efficient. Further, since the mounted portion and the mounting portion are configured in a simple manner of a through hole and an insertion mounting portion, the structure of the entire band clamp can be simplified.

Further, as an aspect of the present invention, the insertion mounting portion may include a mounting shaft portion passing through the through hole, and a distal end enlarged portion provided at a distal end in the insertion direction of the mounting shaft portion.
According to the present invention, even if a force is applied to the regulating portion in a direction in which the insertion attachment portion is removed from the through hole after the insertion attachment portion is inserted into the through hole, the enlarged end portion is moved from the through hole. It can be brought into contact with the peripheral edge. Thereby, it is possible to suppress the restriction part from coming off from the band part, and it is possible to improve the reliability of the work. Furthermore, since the regulating portion is prevented from coming off the band portion, the band portion is pulled beyond a position where an appropriate amount of wrapping is achieved, and excessive tightening of the corrugated gate by the band portion can be further suppressed.

Further, as an aspect of the present invention, the enlarged tip portion may be formed with a diameter that allows it to be inserted into the recess of the corrugate.
According to this invention, the enlarged end portion that protrudes from the band portion toward the corrugate in the wrapped state can be disposed within the recess of the corrugate. Thereby, the enlarged end portion can avoid obstructing the tightening of the corrugate by the band portion, and the enlarged end portion located in the recess of the corrugate can prevent the corrugate from shifting with respect to the band clamp. Can be suppressed.

Further, as an aspect of the present invention, the through hole is configured with an enlarged hole portion into which the enlarged tip portion can be inserted, and a shaft hole portion through which the mounting shaft portion can be inserted, but through which the enlarged tip portion cannot be inserted; The hole portion and the shaft hole portion may be arranged in the longitudinal direction of the band portion and communicate with each other.

In this invention, when inserting the insertion attachment portion into the through hole, the enlarged tip portion is inserted through the enlarged hole portion, so that the restriction portion can be easily attached to the attachment portion. Furthermore, after the regulating portion is installed, the insertion attachment portion is moved so that the attachment shaft is located within the shaft hole, so that the enlarged tip portion comes into contact with the peripheral edge of the shaft hole and is removed. It will play the role of a retainer. Thereby, the convenience of the regulating section can also be improved.

Further, when the through hole is configured such that the enlarged hole portion is disposed on the side in the tension direction of the band portion with respect to the shaft hole portion, when the restriction portion abuts the buckle portion, Then, a force from the enlarged hole portion toward the shaft hole portion acts on the insertion mounting portion. Then, the movement of the mounting shaft into the enlarged hole is effectively suppressed, and the enlarged hole preferably serves as a retainer, which effectively prevents the regulating part from coming off from the mounted part. can be suppressed. Therefore, it is more preferable to handle the restriction part after the work of attaching the band clamp to the corrugate by leaving the restriction part in the inserted state.

On the other hand, when the through hole is configured such that the shaft hole portion is disposed on the side in the tension direction of the band portion with respect to the enlarged hole portion, when the restriction portion abuts the buckle portion, Then, a force from the shaft hole toward the enlarged hole acts on the insertion mounting portion. Then, the mounting shaft moves into the enlarged hole, and the enlarged hole no longer functions as a retainer, making it easier to remove the regulating portion from the mounted portion. Therefore, it is more preferable to remove the restricting portion from the band clamp when handling the restricting portion after the work of attaching the band clamp to the corrugate.

As described above, according to the present invention, the regulating portion can be easily attached to the mounted portion, and the convenience of the regulating portion can be increased, and the regulating portion can be removed after the installation work to the corrugate. It is also possible to obtain a band clamp depending on the handling of the part.

According to this invention, it is possible to provide a band clamp that can be easily and efficiently attached to a corrugated gate.

Using such a band clamp 1, the corrugate 100 can be fixed at a predetermined position on the vehicle 200 by attaching the vehicle attachment part 3 to the attachment point 201 while the corrugate 100 is held by the corrugate holding part 2. .

Next, the overall configuration of the band clamp will be briefly described based on FIGS. 2 to 6.
Here, FIG. 2 shows a side view of the band clamp 1 attached to the corrugated gate 100, and FIG. 3 shows an explanatory view of the band part 10 constituting the band clamp 1 in an expanded state. FIG. 4 shows an explanatory diagram of the buckle part 20 that constitutes the band clamp 1, FIG. 5 shows an explanatory diagram of the regulating part 30 that constitutes the band clamp 1, and FIG. 6 shows the state in which the regulating part 30 is assembled to the band clamp 1. An explanatory diagram is shown.

To explain FIG. 3 in detail, FIG. 3(a) is a view of the band clamp 1 with the band portion 10 expanded as seen from the outer surface side which is the radially outer side when the band portion 10 is wrapped around the corrugate 100. 3(b) shows the band clamp 1 in the same state as seen from the inner surface side of the band portion 10, which is the radially inner side when the band portion 10 is wrapped around the corrugate 100, and FIG. 3(c) shows the band clamp 1 in the same state. shows the band clamp 1 in the same state as viewed from the side of the band clamp 1.

Further, to explain FIG. 5 in detail, FIG. 5(a) shows an explanatory diagram of the configuration of the regulating part 30, and FIG. 5(b) shows an explanatory diagram of the state in which the regulating part 30 is attached to the band clamp 1, FIG. 5(c) shows a cross-sectional view showing a state in which the restricting part 30 is attached to the band clamp 1.

As shown in FIG. 2, the corrugate holding part 2, which constitutes the band clamp 1 together with the vehicle attachment part 3, includes a band part 10 that is wrapped around the outer circumference of the corrugate 100, and a buckle part that fixes the band part 10 in a state where it is wrapped around the corrugate 100. 20, and a regulating section 30 that comes into contact with the buckle section 20 to regulate the amount of wrapping of the band section 10.

In other words, the corrugate holding part 2 is configured to hold the corrugate 100 by fixing the band part 10 around which the corrugate 100 is wound by the buckle part 20 while regulating the amount of wrapping of the band part 10 by the regulating part 30.

Further, the vehicle attachment part 3 is configured as an anchor, and the band clamp 1 can be fixed to the vehicle 200 by inserting the vehicle attachment part 3 into a notch provided at a predetermined attachment point 201 in the vehicle 200.

As shown in FIG. 3, the band portion 10 includes an engaged portion 11 to be engaged with the buckle portion 20, a plurality of attached portions 12 to which the regulating portions 30 are attached, and a shaft that can be fitted into the recess 100a of the corrugated gate 100. A directional convex portion 13 is provided.

As shown in FIG. 3(a), the engaged portion 11 is formed on the outer surface side of the band portion 10, and includes a plurality of engaged protrusions 11a that are engaged with engaging protrusions 22 of the buckle portion 20, which will be described later. It is formed continuously in the axial direction (hereinafter simply referred to as the axial direction refers to this direction), which is the direction in which the band portion 10 extends.
Specifically, the engaged portion 11 is provided in an area excluding the attached portions 12 from the attached portion 12a closest to the buckle portion 20 to around the tip of the band portion 10.

The mounted portion 12 is a region where the regulating portion 30 is mounted at a position where the band portion 10 is wrapped around the corrugated gate 100 by a predetermined amount when the band portion 10 is wound around the corrugated gate 100.
That is, with the regulating part 30 attached to the attached part 12 at a predetermined position, the tip of the band part 10 is inserted into the buckle part 20, and the band part 10 is wrapped around the corrugate 100, as shown in FIG. 6, which will be described later. As the winding progresses, the restricting part 30 gradually approaches the buckle part 20, and the restricting part 30 comes into contact with the buckle part 20 when a predetermined amount of winding is achieved.

In other words, if the regulating part 30 is attached to the attached part 12 at a specific position, the regulating part 30 will come into contact with the buckle part 20 when the amount of wrapping corresponds to the attached part 12 at that position.
In this way, the mounted portion 12 functions as a region for mounting the regulating portion 30 at a position where the band portion 10 is wrapped around the corrugated gate 100 by a predetermined amount.

The attached portion 12 is composed of through holes that penetrate the band portion 10 in the thickness direction, and a plurality of through holes (four in this embodiment) are provided at predetermined intervals in the axial direction.
Particularly, in this embodiment, each of the attached parts 12 is provided corresponding to the diameter of the corrugated gate 100, such as φ10, φ15, φ20, φ25, etc., to be fixed with the band clamp 1. In the mounted portion 12, they are arranged in order from the corresponding small diameter to large diameter from the buckle portion 20 side, that is, from the base side to the tip end. In the present embodiment, in the band part 10, the attached part 12a for the φ10 corrugate 100, the attached part 12b for φ15, the attached part 12c for φ20, and the attached part 12d for φ25 are located on the base side (Fig. 3 (left side in FIG. 3) toward the tip (right side in FIG. 3).

Then, each fitted part 12 wraps the band part 10 around a corrugated gate 100 having a predetermined diameter, and when the regulating part 30 attached to the fitted part 12 corresponding to the diameter comes into contact with the buckle part 20, The band portions 10 are provided at positions where the amount of wrapping is appropriate for the corrugate 100 having the diameter. For example, when the band part 10 is wrapped around the corrugate 100 of φ10, the to-be-attached part 12a is located at a position where the amount of wrapping is appropriate for the corrugate 100 of φ10, and the regulating part 30 as shown in FIG. It is provided at a position where it comes into contact with 20.

In other words, by attaching the regulating part 30 to the fitted part 12 corresponding to the diameter of the corrugated gate 100 to be fixed, each mounted part 12 is regulated at a position where an appropriate amount of wrapping is achieved for the corrugated gate 100 of that diameter. The part 30 can be brought into contact with the buckle part 20.

The appropriate wrapping amount is such that the tightening force exerted by the band portion 10 on the corrugate 100 of a predetermined diameter is sufficient to hold the corrugate 100, and is such that the corrugate 100 is not unintentionally deformed. It refers to the amount of wrapping that gives strength.

As shown in FIGS. 3(b) and 3(c), the axial convex portion 13 is formed on the inner surface side of the band portion 10, more specifically, on the radially inner side when the band portion 10 is wound around the corrugate 100. It is provided on the inner surface side of the band portion 10, which is the side), and extends in the axial direction.

More specifically, the axial convex portion 13 is formed on the same line as the straight line connecting each mounted portion 12 . The axial convex portion 13 is formed over a portion of the inner surface of the band portion 10 excluding the portion where the attached portion 12 is formed.

Moreover, the axial convex part 13 is a part for intervening in the space formed by the recess 100a of the corrugate 100 when the band part 10 is wound around the corrugate 100, and is a part for fixing the corrugate 100 to the vehicle 200. Later, it functions as a part that suppresses lateral displacement of the corrugated gate 100 (positional displacement in the axial direction in the corrugated gate 100).

Therefore, the width and shape of the axial convex portion 13 are configured to fit into the recess 100a of the corrugate 100, and are complementary to the width and shape of the recess 100a. It is made up of various widths and shapes.

To explain the buckle part 20, as shown in FIG. 4, the buckle part 20 is formed with an insertion hole 21 through which the band part 10 can be inserted. Further, on the inner surface of the insertion hole 21 on the side of the vehicle attachment part 3, there is an engagement protrusion that engages with each engaged protrusion 11a forming the engaged part 11 when the band part 10 is inserted into the insertion hole 21. The piece 22 is formed into a protruding shape.

Then, the engaging protrusion 22 engages with one of the engaged protrusions 11a of the band part 10 inserted into the insertion hole 21 of the buckle part 20, thereby fixing the band part 10 with the corrugate 100 wrapped around it. be able to.

Note that the engaged protrusion 11a and the engaging protrusion 22 allow the band portion 10 to move in the direction in which the band portion 10 tightens the corrugated gate 100 more, while allowing the band portion 10 to move in the opposite direction. The band portion 10 inserted into the insertion hole 21 can be fixed.

To explain the restriction part 30, as shown in FIG. The mounting portion 31 is configured as an insertion mounting portion that is inserted through the mounting portion 12 formed of a through hole.

Further, as shown in FIG. 5(b), the regulating section 30 is configured to be attached to the attached section 12 from the direction of the outer circumferential side of the band section 10 in the wrapped state wrapped around the corrugated gate 100.
That is, the regulating part 30 is attached to the attached part 12 by inserting the attached part 31 into the attached part 12, and when the amount of wrapping corresponds to the attached part 12, the regulating part 30 is attached to the attached part 12. The contact portion 32 comes into contact with the buckle portion 20.

As shown in FIGS. 5(a) and 5(c), the mounting portion 31 includes a mounting shaft portion 31a that passes through the mounting portion 12, and a distal enlarged portion 31b provided at the distal end in the insertion direction of the mounting shaft portion 31a. It consists of The mounting shaft portion 31a is formed in a cylindrical shape, and the enlarged tip portion 31b is formed in a conical shape with the bottom facing toward the contact portion 32. When inserted into the mounting portion 12, the enlarged tip portion 31b is entirely covered. It is designed so that it is arranged outside the mounting section 12 and only the mounting shaft section 31a is arranged inside the mounting section 12.

The diameter of the bottom surface of the enlarged tip portion 31b is formed to be larger than the diameter of the attached portion 12, and is configured to function as a retainer for the restricting portion 30 to come off.
Note that at least the enlarged tip portion 31b is made of an elastically deformable material, and the enlarged tip portion 31b can be inserted into the attached portion 12.

Further, the enlarged end portion 31b is formed to have a diameter that can be inserted into the recess 100a, and similarly to the axial convex portion 13, when the band portion 10 is wound around the corrugate 100, a space is formed by the recess 100a of the corrugate 100. The enlarged tip portion 31b can be interposed therebetween.

Furthermore, the abutment part 32 is formed in a wedge shape that is inserted between the band part 10 and the buckle part 20 in a wrapped state in which the band part 10 is wound around the corrugated gate 100. More specifically, for example, as shown in FIG. It is formed in a shape corresponding to the space S formed by the band part 10 and the buckle part 20 in a state where the band part 10 is tightening the corrugate 100 as shown in FIG.
Note that if the shape of the space S changes significantly depending on the position of the mounted part 12 to which the regulating part 30 is attached, a regulating part 30 having a contact part 32 corresponding to each position may be prepared. .

Next, a method for attaching the band clamp 1 configured as described above to the corrugated gate 100 will be briefly described based on FIGS. 6 and 7.
FIG. 6 is an explanatory diagram showing each stage of attaching the band clamp 1 to the corrugated gate 100.

First, when attaching the band clamp 1 to the corrugated gate 100, as shown in FIG. A corrugate 100 is interposed between the buckle parts 20, and the tip of the band part 10 is inserted into the insertion hole 21 of the buckle part 20.

Then, as shown in FIGS. 6(b) and 6(c), the tip of the band portion 10 inserted into the insertion hole 21 is gradually pulled, and as shown in FIG. 6(d), the regulating portion 30 is attached to the buckle portion 20. When they come into contact, in other words, when the regulating part 30 is inserted between the band part 10 and the buckle part 20, the band part 10 is tightened around the corrugate 100 with an appropriate amount of wrapping, and the corrugate holding part 2 tightens the corrugate. 100 can be held properly. At this point, the work of attaching the band clamp 1 to the corrugated gate 100 is completed.

Further, FIG. 7 is a diagram illustrating a state in which the band clamp 1 is attached to the corrugated gate 100, and shows a cross-sectional view taken along the line AA in FIG. 6(d). As shown in FIG. 7, when the band clamp 1 is attached to the corrugate 100 as shown in FIG. .

According to the band clamp 1 configured in this way, by attaching the regulating part 30 to the attached part 12 corresponding to the diameter of the corrugated gate 100 to be fixed, when tightening the corrugated gate 100 by pulling the band part 10, The contact portion 32 can be brought into contact with the buckle portion 20 at a position where the amount of wrapping is appropriate for the diameter of the corrugate 100. As a result, the operator can easily know the position where the band portion 10 has an appropriate amount of wrapping, and when attaching the band clamp 1 to the corrugated gate 100, the operator can easily check the tightening condition of the band portion 10. It becomes possible to perform tasks easily without paying attention.

Furthermore, since the contact portion 32 contacts the buckle portion 20 at a position where the amount of wrapping is appropriate, the band portion 10 is prevented from being pulled beyond the position where the amount of wrapping is appropriate. Thereby, in the work of attaching the band clamp 1 to the corrugate 100, excessive tightening of the band portion 10 to the corrugate 100 can be suppressed when tightening the corrugate 100 by pulling the band portion 10. Therefore, in the work of attaching the band clamp 1 to the corrugated gate 100, the tightening work can be performed using a band gun instead of manually.

As described above, according to the band clamp 1, in the installation work to the corrugated gate 100, in order to fix the band part 10 with an appropriate wrapping amount according to the diameter of the corrugated gate 100, the operator can adjust the tightening condition of the band part 10. Tightening work using a band gun can be performed without special awareness and without manual work.

In addition, since the abutting part 32 is formed in a wedge shape that is inserted between the band part 10 and the buckle part 20 in the wrapped state, when the abutting part 32 abuts the buckle part 20, the abutting part 32 Since the portion 32 is inserted between the band portion 10 and the buckle portion 20, displacement of the contact portion 32 with respect to the buckle portion 20 can be suppressed.

Since the band portion 10 is provided with the axial convex portion 13, the axial convex portion 13 can be fitted into the concave portion of the corrugated gate 100 in the wrapped state. can be suppressed.

In addition, since the attached part 12 is configured with a through hole and the attached part 31 is configured as an insertion attachment part that is inserted through the through hole, it is possible to easily insert the attached part 31 into a predetermined attached part 12. The restriction part 30 can be attached. Further, since the mounted portion 12 and the mounted portion 31 are configured in a simple manner of a through hole and an insertion mounting portion, the overall structure of the band clamp 1 can be simplified.

Further, since the mounting portion 31 is composed of the mounting shaft portion 31a and the enlarged tip portion 31b, after the mounting portion 31 is inserted into the mounting portion 12, the mounting portion 31 is inserted from the mounting portion 12 into the regulating portion 30. Even if a force in the direction of withdrawal is applied, the enlarged tip portion 31b can be brought into contact with the peripheral edge of the attached portion 12.

Thereby, the restriction part 30 can be prevented from coming off from the band part 10, and the reliability of the work can be improved. In addition, since the regulating portion 30 is prevented from coming off the band portion 10, the band portion 10 is pulled beyond the position where the appropriate wrapping amount is achieved, and excessive tightening of the band portion 10 to the corrugated gate 100 occurs. can be suppressed.

Furthermore, since the enlarged end portion 31b is formed with a diameter that allows insertion into the recess of the corrugate 100, the enlarged end portion 31b, which protrudes from the band portion 10 toward the corrugate 100 in the wrapped state, can be inserted into the recess of the corrugate 100. It can be placed inside.

Thereby, it is possible to avoid that the enlarged end portion 31b obstructs the tightening of the corrugate 100 by the band portion 10, and the enlarged end portion 31b located in the recess 100a of the corrugate 100 allows the corrugate 100 to be positioned with respect to the band clamp 1. Misalignment can be suppressed.
In this way, according to the band clamp 1 of this embodiment, the work of attaching the band clamp 1 to the corrugated gate 100 can be performed easily and efficiently.

This invention is not limited to the configuration of the above-described embodiments, and can be implemented in many other embodiments.

For example, in the above description, the wire harness 101 is used as the exterior of the corrugated gate 100, but the wire harness 101 is not necessarily used, and various materials such as optical fibers may be used as the exterior of the corrugated gate 100.

Further, the shapes and configurations of the vehicle attachment portion 3 and the attachment portion 201 for attaching the vehicle attachment portion 3 to the attachment portion 201 of the vehicle 200 illustrated in the above explanation, and the shape and configuration of the attachment portion 201 for fixing the band portion 10 to the buckle portion 20 are also explained. The shapes and configurations of the band portion 10 and the buckle portion 20 are merely examples, and various shapes may be used as long as one can be attached or fixed to the other.

Further, the shapes and configurations of the mounted part 12 and the regulating part 30 for mounting the regulating part 30 on the mounted part 12 illustrated in the above description are merely examples, and the regulating part 30 can be mounted on the mounted part 12. Various types may be used as long as they are suitable.

To list an example, for example, the mounting portion 31 may have only the mounting shaft portion 31a and may not include the enlarged tip portion 31b. Even when the distal end enlarged portion 31b is provided, unlike the above description, it may have a smaller diameter than the diameter of the attached portion 12, or may have a shape other than a cone. Moreover, the mounted part 12 may not be configured as a through hole, but the mounted part 12 and the mounted part 31 may be configured as an engagement mechanism in which one engages with the other. In addition, the number of attached parts 12 is not limited to four, but may be two or more.

For example, with reference to FIGS. 8 to 11, another embodiment will be described in which a mounting portion 14 having a configuration different from that of the mounting portion 12 described above is employed. In addition, in this other embodiment, the structure other than the attachment part 14 is the same structure as the structure of the band clamp 1 of the above-mentioned description.

As shown in FIG. 8, in the other embodiment, the mounted portion 14 has an enlarged hole 14a into which the enlarged tip portion 31b can be inserted, and a shaft hole into which the enlarged tip portion 31b cannot be inserted. The enlarged hole portion 14a and the shaft hole portion 14b are arranged in the longitudinal direction (axial direction) of the band portion 10 and are configured to communicate with each other.

By configuring the mounted portion 14 in this manner, according to the present invention, the regulating portion 30 can be easily mounted on the mounted portion 14, and the convenience of the regulating portion 30 can be improved.

Specifically, FIG. 9 is a diagram showing the state of each stage of mounting the regulating part 30 on the mounted part 14, and as shown in FIG. 9(a), the mounting part 31 is attached to the mounted part 14. At the time of insertion, the restricting portion 30 can be easily attached to the attached portion 14 by inserting the enlarged tip portion 31b into the enlarged hole portion 14a.

As shown in FIGS. 9(b) and 9(c), after the regulating part 30 is installed, the distal end is enlarged by moving the regulating part 30 so that the mounting shaft part 31a is located inside the enlarged hole part 14a. The portion 31b comes into contact with the peripheral edge of the shaft hole portion 14b, and serves as a retainer. Thereby, the convenience of the regulating section 30 can also be improved.

Further, as shown in FIG. 10(a), when the attached portion 14 is configured such that the enlarged hole portion 14a is disposed on the side of the tension direction T of the band portion 10 with respect to the shaft hole portion 14b, As shown in FIG. 10(b), when the regulating portion 30 abuts the buckle portion 20, a force Fa directed from the enlarged hole portion 14a toward the shaft hole portion 14b is applied to the mounting portion as shown in FIG. 10(c). 31.

This prevents the mounting part 31 from moving into the enlarged hole part 14a, and since the enlarged hole part 14a suitably serves as a retainer, it is possible to prevent the regulating part 30 from coming off from the mounted part 14.
Therefore, when handling the restriction part 30 after the work of attaching the band clamp 1 to the corrugated gate 100, it is more preferable to leave the restriction part 30 in the inserted state.

On the other hand, as shown in FIG. 11(a), when the attached part 14 is configured such that the shaft hole part 14b is arranged on the side of the tension direction T of the band part 10 with respect to the enlarged hole part 14a, As shown in FIG. 11(b), when the regulating portion 30 abuts the buckle portion 20, a force Fb directed from the shaft hole portion 14b toward the enlarged hole portion 14a is applied to the mounting portion as shown in FIG. 11(c). 31.

Then, as shown in FIG. 11(d), the mounting portion 31 moves into the enlarged hole 14a, and the enlarged hole 14a no longer functions as a retainer, so as shown in FIG. 11(e). , the regulating section 30 can be easily removed from the mounted section 14.
Therefore, it is more preferable to remove the regulating part 30 from the band clamp 1 when handling the regulating part 30 after the work of attaching the band clamp 1 to the corrugated gate 100.

In this way, by configuring the mounting portion 14 instead of the mounting portion 12 described above, it is also possible to configure the band clamp 1 in accordance with the handling of the regulating portion 30 after the attachment work to the corrugated gate 100.

In this embodiment, the contact part 32 adopts a wedge shape inserted between the band part 10 and the buckle part 20, which corresponds to the space S, but is not limited to this, and can have a shape that acts as a wedge. Various types may be adopted.

Alternatively, a portion for receiving the tip of the abutting portion 32 may be provided between the band portion 10 and the buckle portion 20, and the tip of the abutting portion 32 may be fitted into the portion as a wedge. Further, it does not necessarily have to be wedge-shaped, and may be any shape such as a rectangular parallelepiped as long as the buckle portion 20 can come into contact with it.

The width and shape of the axial convex portion 13 are not limited to those of this embodiment, and it is sufficient that the width and shape fit within the recess 100a to the extent that lateral displacement of the corrugated gate 100 with respect to the band clamp 1 can be suppressed.

Furthermore, in the above description, the axial convex portions 13 are those extending in a solid line shape, but block-shaped axial convex portions 13 are arranged intermittently at equal or various intervals in the axial direction. They may be scattered throughout the area.
In particular, when a material with high hardness is used for the band portion 10, if the axial convex portions 13 are arranged to be scattered, the axial convex portions 13 will be less likely to interfere with the winding of the band portion 10. In addition, a configuration may be adopted in which the band portion 10 does not include the axial convex portion 13.

In this embodiment, the vehicle attachment part 3 is connected to the buckle part 20 of the corrugate holding part 2, but the invention is not limited to this. For example, as shown in FIG. 30 may be connected.
