[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0022] Furthermore, although the multiple wiring fixtures 1 may be individually distinguished and expressed as wiring fixtures 1A, 1B, and 1C, when there is no need to particularly distinguish between the individual wiring fixtures 1, they will simply be referred to as wiring fixture 1.

[0023] <<1. Overview of Wiring Fixtures>> One embodiment of the present invention relates to a wire fixing device that enables an operator to easily determine whether or not a fixed wire maintains linearity. Hereinafter, an overview of the wire fixing device according to this embodiment will be described with reference to FIG.

[0024] 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, as an example of a method for measuring the distortion or temperature distribution of a structure (e.g., a ship), there is BOTDR (Brillouin Optical Time Domain Reflectometry), in which an optical fiber cable is laid in the structure and backscattering in the optical fiber is measured. When performing measurements using BOTDR, it is sometimes desirable to fix the optical fiber cable while maintaining its linearity along the shape of the structure.

[0025] Fig. 1 is an explanatory diagram for explaining the outline of the wiring fastener 1 according to the present embodiment. The wiring fastener 1 according to the present embodiment is a fastening jig for fastening the wiring W at an arbitrary position. For example, as shown in Fig. 1, the wiring W can be fastened without bending by fastening the wiring W at a plurality of positions as in the wiring fastener 1A, the wiring fastener 1B, and the wiring fastener 1C. Note that Figs. 1 and 2 are simplified views of the wiring fastener 1 for the convenience of explaining the outline, and differ from the appearance of the actual wiring fastener 1.

[0026] Furthermore, the wiring fixture 1 according to this embodiment supports a light-emitting body 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-receiving element 105 that receives light emitted by a light-emitting body 101 possessed by another wiring fixture 1 that is installed on the opposite side of the light traveling direction from a certain wiring fixture 1.

[0027] For example, in FIG. 1, wiring fixture 1A supports light-emitting body 101A that emits light L parallel to the axial direction of wiring W at the gripping position of wiring W, and has light-receiving body 105A that receives light L emitted by light-emitting body 101B of wiring fixture 1B installed on the opposite side to the traveling direction of light L emitted by light-emitting body 101A supported by wiring fixture 1A.

[0028] The worker adjusts the position of the wiring fastener 1A or the wiring fastener 1B so that light L emitted from the light emitting body 101B supported by the wiring fastener 1B strikes the light receiving target 105A of the wiring fastener 1A.

[0029] It is also possible that there may be an obstacle on the route where the worker wants to install the wiring fixing device 1. In such a case, conventionally, the worker would have to reselect a route that does not have any obstacles, install the wiring fixing device 1 on the reselected route, and fix the wiring. In this way, a situation may arise where the worker is unable to fix the wiring on the route originally planned.

[0030] Furthermore, if an obstacle is present in the path where the wiring fastener 1 is installed, the worker may have to shift the wiring fastener 1 and install it only in the area affected by the obstacle to fasten the wiring.

[0031] 2 is an explanatory diagram for explaining an example of a situation in which an obstacle A is present. For example, there is a situation in which a worker cannot install the wiring fastener 1B due to the presence of the obstacle A. In such a situation, the worker installs the wiring fastener 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.

[0032] 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. Hereinafter, the wiring fixture 1 according to this embodiment will be described with reference to Fig. 3.

[0033] <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 part 10, a fixing part 20, and a movable part 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.

[0034] The wire 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 wire 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 light having linearity emitted by the light emitter 101 may be, for example, laser light. In addition, the wire 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 wire gripping part 10 is variable relative to the fixed part 20. In addition, the position of the wire gripping part 10 is variable in a direction intersecting the axial direction of the wire.

[0035] The fixing part 20 includes a fixing part main body 200 and a fixing screw S3, and is fixed to an arbitrary 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 part of the fixing part main body 200. In other words, the fixing part 20 can be fixed to an arbitrary installation location where the fixed object F is present.

[0036] 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 connected to the wiring gripping part 10 may be referred to as a gripping part connection surface, and the surface of the movable part 30 connected to the fixed part 20 may be referred to as a fixed part connection surface.

[0037] The wire gripping portion 10 and the movable portion 30 are connected by a screw S2, and the fixed portion 20 and the movable portion 30 are connected by a screw S4.

[0038] 4 to 6, configuration examples of the wire gripping part 10, the fixed part 20, and the movable part 30 will be described in order. In the following description, the direction of the wire fastener 1 shown in FIG. 3 will be described as a front view.

[0039] <2.2. Configuration example of the wiring gripping portion 10> Fig. 4A is a front view of the gripper main body 100 according to this embodiment. The wire gripper 10 according to this 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.

[0040] Furthermore, the grip body 100 may have a hole to 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, as another example of a method for supporting the light emitting body 101, the grip body 100 may be provided with the light emitting body 101 in advance.

[0041] The gripping portion main 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 wire gripping portion 10 to grip the wire by clamping it with the plate PL.

[0042] Furthermore, the worker attaches the screw S2 to the screw hole H2A via the movable part 30 shown in Fig. 3. Note that the number of the screw holes H1 and the screw holes H2A shown in Fig. 4A may be any number.

[0043] 4B is a rear view of the gripping body 100 according to this embodiment. The wiring gripping part 10 has a light receiving target 105 that receives light emitted by a light emitter of another wiring fastener installed on the opposite side of the wiring fastener 1 in the light traveling direction. For example, the wiring gripping part 10 has a light receiving target 105 having 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 part 10 located in front.

[0044] 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 required accuracy.

[0045] The configuration example of the wire gripping portion 10 according to this embodiment has been described above. Next, a configuration example of the fixing portion 20 according to this embodiment will be described with reference to FIG.

[0046] <2.3. Configuration example of fixed part 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 fastener 1 to an arbitrary installation location by clamping the fixing object F with the fixing screw S3 shown in Fig. 3.

[0047] The worker attaches the screw S4 to the screw hole H4B via the movable part 30 shown in FIG.

[0048] 2.4. Configuration example of the movable part 30 FIG. 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 coupling surface along the horizontal direction (X direction). Although FIG. 6A shows an example in which the shape of the elongated hole H4C is rectangular, the elongated hole H4C according to this embodiment is not limited to such an example. The shape of the elongated hole H4C may be a rectangle having 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 coupling.

[0049] Fig. 6B is an explanatory diagram showing a state in which the fixed part 20 and the movable part 30 are connected. As shown in Fig. 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 wire gripping part 10 while avoiding obstacles in the horizontal direction.

[0050] 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 grip part connection surface. The movable part 30 may have an elongated hole on at least one of the grip part connection surface and the fixed part connection surface described above.

[0051] Fig. 7B is an explanatory diagram showing a state in which the wire gripping part 10 and the movable part 30 are connected. As shown in Fig. 7B, the wire 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 wire gripping part 10 while avoiding obstacles in the height direction.

[0052] An example of the configuration of the wiring fastener 1 according to the present embodiment has been described above. As described above, according to the wiring fastener 1 according to the present embodiment, the worker can adjust the position of the wiring fastener 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 holding part 10 or the movable part 30 so that the light emitted by the light-emitting body 101 supported by the wiring holding part 10 hits the light-receiving target 105 of the wiring holding part 10 provided on the front wiring fastener 1. This allows the worker to fix the wiring while maintaining the linearity of the wiring.

[0053] 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. As a method for determining whether the light is incident from the direction of the central axis of the light-receiving target 105, there is a method of checking the degree of circularity of the light incident on the light-receiving target. For example, when 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 the light incident from the shape of the light incident on the light-receiving target.

[0054] As another example of a method for determining whether or not light striking the light-receiving object is incident from the direction of the central axis of the light-receiving object, creative innovation may be applied to the configuration of the wire gripping part 10. In the following, regarding creative innovation in the configuration of the wire gripping part 10, modified examples of the wire gripping part 10 will be described with reference to Figs. 8 to 10.

[0055] <<3. Modifications>> <3.1. First modified example> 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 straight 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.

[0056] <3.2. Second modified example> 9 is an explanatory diagram for explaining a second modified example of the wire gripping part 10. The wire 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.

[0057] Furthermore, the wire gripping part 10 may have the light receiving target 105 as a groove of the wire gripping part 10. As a result, the light receiving target 105 that is the groove of the wire 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 wire is maintained by checking whether the light emitted by the light emitter 101 is striking the light receiving target 105 of the wire gripping part 10 in front.

[0058] <3.3.Third modified example> 10 is an explanatory diagram for explaining a third modified example of the wire gripping part 10. The wire gripping part 10 supports a light emitter 101 on each of two surfaces perpendicular to the axial direction of the wire W, and may have a light receiving target 105.

[0059] In this case, the two light emitters 101 included in the wire gripping part 10 emit light L in both directions. Then, the worker adjusts the position of the wire gripping part 10 so that the light L incident from both directions hits the two corresponding light receiving targets 105. This allows the wire fixing tool 1 to fix the wire W while maintaining the linearity of the wire W with higher accuracy.

[0060] <<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.

[0061] For example, in the present specification, an example has been described in which the wire gripping part 10 according to the present embodiment is provided with the light receiving target 105, but the wire fastener 1 according to the present embodiment may be arranged at regular intervals by an operator, and a wire at a predetermined position of the interval may be used as the light receiving target. In this case, the light emitter 101 may be supported by the wire gripping part 10 so as to emit light in a direction in which the wire W can maintain its linearity.

[0062] Moreover, the wiring fixture 1 according to this embodiment does not necessarily have to have a movable mechanism such as the movable part 30.

[0063] Further, in the present specification, an example has been described in which the position of the wire gripping part 10 is variable in the translation direction relative to the fixed part 20, but the position of the wire gripping part 10 may be variable in the rotation direction relative to the fixed part 20. This allows the worker to adjust the position of the wire gripping part 10 with a higher degree of freedom. [Explanation of symbols]
