The preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. Note that in this specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

In addition, the multiple wiring fixtures 1 may be distinguished and expressed as wiring fixtures 1A, 1B, and 1C, but when there is no need to distinguish between the wiring fixtures 1, they will simply be referred to as wiring fixture 1.

＜＜1. Overview of wiring fixtures＞＞
An embodiment of the present invention relates to a wire fastener that enables an operator to easily determine whether or not a fixed wire maintains linearity. Hereinafter, an overview of the wire fastener according to the present embodiment will be described with reference to FIG.

In recent years, there are situations where it is desirable to fix wiring to an installation location while maintaining the linearity of the wiring. For example, one method for measuring the distortion and temperature distribution of a structure (e.g., a ship) is Brillouin Optical Time Domain Reflectometry (BOTDR), which lays an optical fiber cable in the structure and measures backscattering in the optical fiber. When measuring with BOTDR, it is sometimes desirable to fix the optical fiber cable in place while maintaining linearity along the shape of the structure.

Figure 1 is an explanatory diagram for explaining the outline of the wiring fixture 1 according to this embodiment. The wiring fixture 1 according to this embodiment is a fixture that fixes the wiring W at any position. For example, as shown in Figure 1, the wiring W can be fixed without bending by fixing the wiring W at multiple positions, such as with wiring fixture 1A, wiring fixture 1B, and wiring fixture 1C. Note that Figures 1 and 2 are simplified views of the wiring fixture 1 for the convenience of explaining the outline, and differ from the actual appearance of the wiring fixture 1.

The wiring fixture 1 according to this embodiment also supports a light emitter 101 that emits light L parallel to the axial direction of the wiring W at the gripping position of the wiring W, and has a light receiver 105 that receives light emitted by the light emitter 101 of another wiring fixture 1 installed on the opposite side of the light traveling direction from a certain wiring fixture 1.

For example, in FIG. 1, the wiring fixture 1A supports a light emitter 101A that emits light L parallel to the axial direction of the wiring W at the gripping position of the wiring W, and has a light receiver 105A that receives light L emitted by a light emitter 101B of a wiring fixture 1B that is installed on the opposite side of the traveling direction of the light L emitted by the light emitter 101A supported by the wiring fixture 1A.

The worker adjusts the position of the wiring fixture 1A or wiring fixture 1B so that the light L emitted by the light emitter 101B supported by the wiring fixture 1B hits the light receiver 105A of the wiring fixture 1A.

It is also possible that there may be an obstacle on the route along which the worker wants to install the wiring fixture 1. In such a case, conventionally, the worker would have to reselect a route that does not have any obstacles, install the wiring fixture 1 on the reselected route, and fix the wiring. In this way, a situation could arise where the worker is unable to fix the wiring on the route originally planned.

In addition, if an obstacle is present in the path where the wiring fixture 1 is installed, the worker may have to shift the wiring fixture 1 and install it only in the area affected by the obstacle to secure the wiring.

Figure 2 is an explanatory diagram for explaining an example of a situation in which an obstacle A is present. For example, there may be a situation in which the worker is unable to install the wiring fixing device 1B due to the presence of the obstacle A. In such a situation, the worker installs the wiring fixing device 1B at a position that avoids the obstacle A and fixes the wiring W, but at the same time, it may become difficult to maintain the straightness of the wiring W.

Therefore, the wiring fixture 1 according to this embodiment is capable of fixing the wiring W while maintaining the linearity of the wiring W even when such an obstacle A is present in the path along which the wiring fixture 1 is to be installed. Below, the wiring fixture 1 according to this embodiment will be described with reference to FIG. 3.

2. Configuration example
<2.1. Overall configuration of wiring fixture 1>
Fig. 3 is an explanatory diagram for explaining a configuration example of the wiring fastener 1 according to the present embodiment. The wiring fastener 1 according to the present embodiment includes a wiring gripping portion 10, a fixing portion 20, and a movable portion 30. In this specification, as shown in Fig. 3, the axial direction of the wiring W is defined as the Z direction, the width direction of the wiring fastener 1 is defined as the X direction, and the height direction of the wiring fastener 1 is defined as the Y direction.

The wiring gripping part 10 includes a gripping part main body 100, a light emitter 101, a plate PL, a screw S1, and a screw S2. The gripping part main body 100, the plate PL, and the screw S1 function as a structure for gripping the wiring W. The light emitter 101 is supported by the gripping part main body 100. It is preferable that the light emitter 101 emits light having linearity. The linear light emitted by the light emitter 101 may be, for example, laser light. In addition, the wiring gripping part 10 is connected to the movable part 30 by clamping the movable part 30 with the gripping part main body 100 and the screw S2. As will be described in detail later, the position of the wiring gripping part 10 is relatively variable with respect to the fixed part 20. In addition, the position of the wiring gripping part 10 is variable in a direction intersecting the axial direction of the wiring.

The fixing part 20 includes a fixing part main body 200 and a fixing screw S3, and is fixed to any installation location. For example, the fixing part main body 200 has a hollow U-shape as shown in FIG. 3. The fixing part 20 is fixed to the fixed object F by clamping the fixed object F between the fixing part main body 200 and the fixing screw S3 with the fixed object F placed in the hollow portion of the fixing part main body 200. In other words, the fixing part 20 can be fixed to any installation location where the fixed object F is present.

The movable part 30 is provided between the wiring gripping part 10 and the fixed part 20, and is movable relative to the fixed part 20. In the following description, the surface of the movable part 30 that is connected to the wiring gripping part 10 may be referred to as the gripping part connection surface, and the surface of the movable part 30 that is connected to the fixed part 20 may be referred to as the fixed part connection surface.

The wiring gripping part 10 and the movable part 30 are connected by a screw S2. The fixed part 20 and the movable part 30 are connected by a screw S4.

Below, with reference to Figures 4 to 6, examples of the configuration of the wiring gripping part 10, the fixed part 20, and the movable part 30 will be described in order. Note that in the following explanation, the direction of the wiring fixture 1 shown in Figure 3 will be described as a front view.

2.2. Configuration example of wire gripping portion 10
4A is a front view of the gripper main body 100 according to the present embodiment. The wire gripper 10 according to the present embodiment has a structure for gripping a wire, and supports a light emitter 101 that emits light parallel to the axial direction of the wire at the gripping position of the wire in a gripped state. The structure for gripping the wire may be, for example, a groove N formed in a straight line as shown in FIG. 4A.

The grip body 100 may have a hole in which the light-emitting body 101 is attached, as an example of a method for supporting the light-emitting body 101. In this case, the light-emitting body 101 is fitted into the hole and supported by the grip body 100. Alternatively, the grip body 100 may be provided with the light-emitting body 101 in advance, as another example of a method for supporting the light-emitting body 101.

The gripper body 100 also has a screw hole H1 and a screw hole H2A. The worker attaches the screw S1 to the screw hole H1 via the plate PL shown in FIG. 3. This allows the wiring gripper 10 to grip the wiring by clamping it with the plate PL.

The worker also attaches the screw S2 to the screw hole H2A via the movable part 30 shown in FIG. 3. Note that the number of screw holes H1 and screw holes H2A shown in FIG. 4A may be any number.

Figure 4B is a rear view of the gripping unit main body 100 according to this embodiment. The wiring gripping unit 10 has a light receiving target 105 that receives light emitted by a light emitter of another wiring fixture installed on the opposite side of the wiring fixture 1 in the light traveling direction. For example, the wiring gripping unit 10 has a light receiving target 105 that has the same central axis as the central axis of the light emitted by the light emitter 101. This allows the worker to more easily determine whether the linearity of the wiring is being maintained by checking that the light emitted by the light emitter 101 is hitting the light receiving target 105 of the wiring gripping unit 10 in front.

Note that the shape, size, or position of the light receiving target 105 according to this embodiment is not limited to the example shown in FIG. 4B. The shape, size, or position of the light receiving target 105 may be changed as appropriate depending on the performance of the light emitting body 101 and the desired accuracy.

The above describes an example of the configuration of the wiring gripping portion 10 according to this embodiment. Next, with reference to FIG. 5, an example of the configuration of the fixing portion 20 according to this embodiment will be described.

2.3. Configuration example of fixed unit 20
Fig. 5 is a plan view of the fixing part main body 200 according to this embodiment. As shown in Fig. 5, the fixing part main body 200 has a screw hole H3B and a screw hole H4B. An operator attaches the fixing screw S3 shown in Fig. 3 to the screw hole H3B. The fixing part 20 fixes the wiring fixing tool 1 to an arbitrary installation location by clamping the fixing object F with the fixing screw S3 shown in Fig. 3.

The worker installs the screw S4 into the screw hole H4B via the movable part 30 shown in Figure 3.

2.4. Configuration example of the movable part 30
6A is a plan view of the movable part 30 according to this embodiment. The movable part 30 has an elongated hole H4C formed in the fixed part connection surface along the horizontal direction (X direction). Although the shape of the elongated hole H4C is shown as a rectangle in FIG. 6A, the elongated hole H4C according to this embodiment is not limited to this example. The shape of the elongated hole H4C may be a rectangle with rounded corners, or may be any shape within the range in which the movable part 30 can move. In addition, the size of the elongated hole H4C may be appropriately changed according to the diameter of the threaded part of the screw used for connection.

Figure 6B is an explanatory diagram showing the state in which the fixed part 20 and the movable part 30 are connected. As shown in Figure 6B, the movable part 30 can be moved by sliding in the horizontal direction (X direction) relative to the fixed part 20. This allows the worker to adjust the position of the wiring gripping part 10 while avoiding obstacles in the horizontal direction.

Figure 7A is a side view of the movable part 30 according to this embodiment. The movable part 30 has an elongated hole H2C formed along the height direction (Y direction) on the gripping part connection surface. Note that the movable part 30 may have an elongated hole on at least one of the gripping part connection surface or the fixed part connection surface described above.

Figure 7B is an explanatory diagram showing the state in which the wiring gripping part 10 and the movable part 30 are connected. As shown in Figure 7B, the wiring gripping part 10 can be moved by sliding in the height direction (Y direction) relative to the movable part 30. This allows the worker to adjust the position of the wiring gripping part 10 while avoiding obstacles in the height direction.

The above describes an example of the configuration of the wiring fixture 1 according to this embodiment. As described above, with the wiring fixture 1 according to this embodiment, the worker can adjust the position of the wiring fixture 1 depending on the presence or absence of an obstacle and the position of the obstacle. Then, the worker adjusts the position of the wiring gripping part 10 or the movable part 30 so that the light emitted by the light-emitting body 101 supported by the wiring gripping part 10 hits the light-receiving target 105 of the wiring gripping part 10 provided on the front wiring fixture 1. This allows the worker to fix the wiring while maintaining the linearity of the wiring.

In order to fix the wiring while maintaining the linearity of the wiring with higher accuracy, it is desirable for the worker to determine whether the light hitting the light receiving target 105 is incident from the direction of the central axis of the light receiving target 105. One method for determining whether the light is incident from the direction of the central axis of the light receiving target 105 is to check the degree of circularity of the light incident on the light receiving target. For example, if light is incident from a direction that forms a large angle with the central axis of the light receiving target 105, the light incident on the light receiving target 105 may be visually recognized by the worker as an ellipse. Therefore, the worker may be able to determine the direction of incidence of the light from the shape of the light incident on the light receiving target.

As another example of a method for determining whether light striking the light-receiving element is incident from the direction of the center axis of the light-receiving element, the configuration of the wiring gripping part 10 may be modified in a creative way. Below, regarding the creative way in which the configuration of the wiring gripping part 10 is modified, the wiring gripping part 10 will be described with reference to Figures 8 to 10.

<<3. Modified Examples>>
<3.1. First Modification>
FIG. 8 is an explanatory diagram for explaining a first modified example of the wiring gripping part 10. The wiring gripping part 10 according to the first modified example may include a light shielding part 110 having a hole with a central axis on the same line as the central axis of the light receiving target 105. As a result, the light shielding part 110 shields the light L that is directed toward the light receiving target 105 and whose angle with the central axis of the light receiving target 105 is equal to or greater than a predetermined value. As a result, the worker can determine whether the linearity of the wiring is maintained by checking whether the light emitted by the light emitter 101 hits the light receiving target 105 of the wiring gripping part 10 in front. Note that FIG. 8 shows an example in which three wiring gripping parts 10 install the wiring W at regular intervals, but the intervals at which the wiring gripping parts 10 grip the wiring W do not necessarily have to be regular.

3.2. Second Modification
9 is an explanatory diagram for explaining a second modified example of the wiring gripping part 10. The wiring gripping part 10 according to the second modified example may have a convex structure C formed along the periphery of the light receiving target 105. The convex structure C blocks light L that is directed toward the light receiving target 105 and forms an angle with the central axis of the light receiving target 105 of a predetermined value or more.

The wiring gripping part 10 may also have the light receiving target 105 as a groove of the wiring gripping part 10. As a result, the light receiving target 105 that is the groove of the wiring gripping part 10 is only struck by light L that forms an angle with the central axis of the light receiving target 105 that is less than a predetermined value. As a result, the worker can determine whether the linearity of the wiring is maintained by checking whether the light emitted by the light emitter 101 is striking the light receiving target 105 of the wiring gripping part 10 in front.

3.3. Third modified example
10 is an explanatory diagram for explaining a third modified example of the wiring gripping part 10. The wiring gripping part 10 supports a light emitter 101 on each of two surfaces perpendicular to the axial direction of the wiring W, and may have a light receiving target 105.

In this case, the two light emitters 101 provided on the wiring gripping part 10 emit light L in both directions. The worker then adjusts the position of the wiring gripping part 10 so that the light L incident from both directions hits the two corresponding light receivers 105. This allows the wiring fixing tool 1 to fix the wiring W while maintaining the linearity of the wiring W with higher accuracy.

<<4. Supplementary Information>>
Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

For example, in the present specification, an example has been described in which the wiring gripping part 10 according to this embodiment is equipped with a light receiving object 105, but the wiring fixing device 1 according to this embodiment may be arranged at regular intervals by the worker, and the wiring at a predetermined position of the interval may be used as the light receiving object. In this case, the light emitter 101 may be supported by the wiring gripping part 10 so as to emit light in a direction in which the wiring W can maintain its linearity.

In addition, the wiring fixture 1 according to this embodiment does not necessarily have to have a movable mechanism such as the movable part 30.

In addition, although an example has been described in this specification in which the position of the wiring gripping part 10 is variable in the translational direction relative to the fixed part 20, the position of the wiring gripping part 10 may be variable in the rotational direction relative to the fixed part 20. This allows the worker to adjust the position of the wiring gripping part 10 with a higher degree of freedom.
