An annular groove 67d is formed between the threaded portion 67a and the unthreaded portion 67b.

  Next, a method for fixing a protective wire using the fixing device configured as described above will be described. The description will be given with reference to FIGS. 6 and 7 in addition to FIGS. 6 and 7 are enlarged views of the VI part and the VII part of FIG. 2, respectively. First, as shown in FIG. 3 and FIG. 5A, the base 71 is inserted into the guide frame 69a, and the thickness adjusting screw 67 is passed through the convex 69c and screwed into the convex 71c. The fixing members 61 are assembled by combining the jaw members 63 and 65. As shown in FIGS. 2 and 6, the protective wire 51 is accommodated inside the pair of jaw members 63, 65, and more specifically, the protective wire 51 is guided and accommodated in the guide recess 69d. Thus, for example, a plate-like attachment arm (fixed point) 37 is sandwiched between the pair of jaw members 63 and 65. As a result, the protection wire 51 can be hooked inside the pair of jaw members 63 and 65 and fixed to the mounting arm 37 in a manner guided in a direction parallel to the surface of the mounting arm 37. The fixing device 61 functions as a clip. When the tips of the pair of jaw members 63 and 65 of the fixing device 61 are pressed against the mounting arm 37, the pair of jaw members 63 and 65 are bent and spread. After that, the pair of jaw members 63 and 65 sandwich the attachment arm 37 by the elastic force of the pair of jaw members 63 and 65, and the fixing device 61 is held by the attachment arm 37. In other words, the attachment of the fixing device 61 to the attachment arm 37 only needs to be pushed into the attachment arm 37 and is completed by a so-called one-touch operation. At that time, since the introduction slopes 73a and 75a are provided at the tips of the pair of jaw members 63 and 65, the fixing device 61 is pushed in against the restoring elastic force of the pair of jaw members 63 and 65. It has become. In addition, since the introduction slopes 73a and 75a are provided with a point 77, the fixing device 61 is less likely to be detached from the fixing destination once it is pushed in.

  Furthermore, the fixing device 61 of the present embodiment can also be fixed by one-touch work in a mode in which the protective wire 51 is hooked in the guide recess and guided in a direction orthogonal to the surface of the mounting arm 37. That is, as shown in FIG. 2 and FIG. 7, for example, plate-like rail brackets (fixed points) are attached to the pair of jaw members 63 and 65 in a state where the protective wire 51 is guided and accommodated in the pair of guide recesses 73 b and 75 b. 49) can be inserted.

  Moreover, when it is going to attach a fixing device using an elastic force in order to implement | achieve a one-touch operation | work as mentioned above, there exist the following problems. That is, when the thickness of the fixation destination is relatively thick, it is difficult to spread the jaw member and attach it to the fixation destination because the pinching force of the pair of jaw members is too strong, and conversely, when the thickness of the fixation destination is relatively thin Even if the fixing destination is sandwiched, the pair of jaw members does not spread so much that the obtained clamping force is too small, and the fixing device may be detached from the fixing destination. For such a problem, in the present embodiment, according to the thickness of the fixing point, the interval between the pair of jaw members 63 and 65 when the fixing point is not sandwiched is appropriately adjusted in advance. The fixing device 61 can be pushed into the fixing destination and can be attached to the fixing destination. Therefore, even if it has the structure as a clip using an elastic force, even if it is attached to a fixing destination of various thicknesses, there is no problem that the mounting becomes difficult or the pinching force is insufficient. Moreover, about the concrete aspect of space | interval adjustment, the thickness adjustment screw 67 is freely rotatable between one of the pair of jaw members 63 and 65, and the insertion / removal in the screw shaft direction is restricted. By being provided so as to be screwed together, it can be completed only by a simple operation of turning the thickness adjusting screw 67, and the distance between the pair of jaw members 63 and 65 as shown in FIG. It is also easy to spread out.

  As described above, according to the present embodiment, the protective wire can be easily fixed to a fixing destination having various thicknesses without drilling or welding. In addition, as a fixing mode, it is possible to fix the guide wire in a direction parallel to the surface with respect to the plate-like fixing destination, and fix the guide wire so as to guide the protection wire in a direction perpendicular to the surface. You can also. Furthermore, it is possible to make the work one-touch by using the elastic force, and even when using the elastic force, it always obtains a suitable holding force for the fixing device even when applied to a fixing destination of various thicknesses. I can.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 8 is an exploded perspective view of the fixing device according to the present embodiment, FIG. 9 is a side view thereof, and (a) is relatively thin, (b) is relative in thickness. The state when it is thick is shown. The fixing device 161 includes a pair of jaw members 163 and 165 for sandwiching the fixing destination in a state where the protective wire 51 is hooked as described later, a thickness adjusting bolt (thickness adjusting screw member) 167, and a tightening bolt (tightening bolt screw member). 179.

  The pair of jaw members 163 and 165 are configured to be separable and assembled, and are formed of a pair of plate members provided in parallel. One jaw member 163 is provided with a threaded hole 169b substantially at the center in the left-right direction L. Further, a pair of left and right screw through holes 181 are formed at an intermediate portion between the sandwiching end portion 163a and the thread groove hole 169b in the jaw member 163. The pair of screw through holes 181 are defined by a flat (unthreaded) cylindrical surface.

  The other jaw member 165 is provided with a pair of left and right screw grooves 183. The pair of screw groove holes 183 is formed by a cylindrical surface having a thread groove. The pair of screw groove holes 183 and the pair of screw through holes 181 are arranged in the separation / assembly direction S and are arranged on substantially the same axis. Further, in the other jaw member 165, a hole is not formed in a region aligned with the screw slot 169b of the pair of jaw members 163 in the separation / assembly direction S.

  The pinching end portions 163a and 165a of the pair of jaw members 163 and 165 are provided with barbs 185 that are pointed in directions approaching each other. In addition, guide recesses 173b and 175b are formed at substantially center portions in the left-right direction L of the sandwiching end portions 163a and 165a, respectively. Each of the guide recesses 173b and 175b is formed by a substantially U-shaped notch opened to the sandwiching end portions 163a and 165a.

  The thickness adjusting bolt 167 is a hexagon socket head bolt, and is screwed into the thread groove hole 169b of one jaw member 163 and abutted against the other jaw member 165. The pair of tightening bolts 179 are also hexagon socket head cap bolts, and have a threaded portion 179a and an unthreaded portion 179b on the shaft portion. The unthreaded portion 179b is located on the head portion 179c side of the shaft portion, and is configured to have an outer diameter that is longer than the screw through hole 181 and sufficiently smaller than the screw through hole 181. The tightening bolt 179 is removably inserted into the screw through hole 181 of one jaw member 163 and is screwed into the thread groove hole 183 of the other jaw member 165. The clamping end portion 163a is more than the thickness adjusting bolt 167. , 165a.

  A pair of protective tubes 187 are arranged between a pair of plate members constituting the pair of jaw members 163 and 165, and the fastening bolts 179 pass through each protective tube 187. That is, each of the protection tubes 187 is positioned around the corresponding fastening bolt 179 and covers the threaded portion (thread) 179a of the fastening bolt 179.

  Next, a method for fixing a protective wire using the fixing device configured as described above will be described. Description will be made with reference to FIGS. 10 and 11 in addition to FIGS. FIG. 10 is a plan view of FIG. 9, illustrating a mode in which the protective wire is attached so as to be orthogonal to the plate, and FIG. 11 is a diagram illustrating a mode in which the protective wire is attached in parallel to the plate. First, as shown in FIGS. 8 and 9A, the thickness adjusting bolt 167 is screwed into the thread groove 169b of one jaw member 163 and abutted against the other jaw member 165, and the tightening bolt 179 is washer. 189, the fixing device 161 is assembled by being inserted into the screw through hole 181 and the protective tube 187 of one jaw member 163 and screwed into the screw groove 183 of the other jaw member 165.

  9 and 10, for example, plate rail brackets (fixed points) are attached to the pair of jaw members 163 and 165 in a state where the protective wire 51 is guided and accommodated in the pair of guide recesses 173b and 175b. ) 49 is inserted. Accordingly, the protective wire 51 can be fixed in a manner guided in a direction orthogonal to the surface of the plate-shaped fixing destination without drilling or welding.

  Also in this embodiment, the fixing device 161 can be attached according to the thickness of the fixing destination. First, the thickness adjusting bolt 167 is turned to widen the gap between the jaw members 163 and 165 to such an extent that the fixing point can be pinched (see FIG. 9B). Further, the jaw members 163 and 165 are arranged so that the fixing destination is inserted between the pair of jaw members 163 and 165. Then, the pair of jaw members 163 and 165 are pulled toward each other by tightening the tightening bolt 179, the pair of jaw members 163 and 165 pinch the fixing destination, and the fixing device 161 is held on the fixing destination.

  As described above, according to the thickness of the fixing destination, the distance between the pair of jaw members 163 and 165 when the fixing destination is not sandwiched is appropriately adjusted in advance, and then the attachment to the fixing destination can be performed. . Therefore, there is no problem that the attachment is difficult or the pinching force is insufficient even when attaching to fixing points of various thicknesses. As for a specific spacing adjustment mode, the thickness adjustment bolt 167 provided in such a mode that only the one jaw member 163 is screwed and the other jaw member 165 is simply abutted is turned. Can be completed with just work. Further, since the thickness adjusting bolt 167 is not screwed to the other jaw member 165, the pair of jaw members 163 and 165 are not connected to each other. For this reason, when the tightening bolt 179 is tightened, the pair of jaw members 163 and 165 are not restrained each other, and the resistance at the time of tightening can be suppressed accordingly. Further, since the fastening bolt 179 penetrating the one jaw member 163 is screwed to the other jaw member 165, the pair of jaw members can be handled during handling without the thickness adjusting bolt 167 being screwed to the other jaw member 165. There is also an advantage that 163 and 165 do not fall apart and the other jaw member 165 does not need to be threaded. Further, since the tightening bolt 179 functions between the thickness adjusting bolt 167 and the fixing destination, an efficient and strong tightening force is applied to the fixing destination. Moreover, in this Embodiment, since the clamping force by a screw is utilized, a fixed point can be pinched | interposed with bigger force. Further, since elasticity is not required for the pair of jaw members 163 and 165, a plate member having higher rigidity and thickness can be used, whereby a bolt that can apply a stronger tightening force to the tightening screw member is provided. Can be adopted. In addition, since the force acts on the fixed tooth against the fixing point during tightening, an effect of making it difficult for the fixing device to come off from the fixing point can be obtained.

  Furthermore, the fixing device 161 of the present embodiment can also fix the protective wire 51 in a manner guided in parallel to the surface of the plate-like fixing destination. (A) of FIG. 11 shows protrusions, such as an attachment arm in the car guide rail vicinity, (b) shows the cross section along the XI-XI line of (a). As shown in FIG. 11, for example, a plate-like attachment that supports the guide plate 191 or the like to the pair of jaw members 163 and 165 in a state where the protective wire 51 is accommodated inside the pair of jaw members 163 and 165. The arm 37 is inserted. As a result, the protective wire 51 can be fixed to the mounting arm 37 in a manner guided in a direction parallel to the surface of the mounting arm 37. Further, in the present embodiment, as described above, the tightening bolt 179 is disposed at a position close to the sandwiching end portions 163a and 165a so that the fixing destination can be sandwiched with a greater force, so that the protective wire 51 is attached. If it tries to fix in the aspect guided in the direction parallel to the surface of the arm 37, the protection wire 51 will be located near the fastening bolt 179. However, in the present embodiment, the protective tube 187 is provided around the tightening bolt 179 between the pair of jaw members 163 and 165. For this reason, even if a clamping screw member is arranged at a position close to the clamping end and a protective wire is passed between the clamping screw member and the fixing destination so that the fixing destination can be inserted with a larger force, the protection can be achieved. It is possible to prevent the wire from being damaged by the tightening screw member.

  As described above, according to the present embodiment, the protective wire can be easily fixed to the fixing destination having various thicknesses without drilling or welding. In addition, as a fixing mode, it is possible to fix the guide wire in a direction parallel to the surface with respect to the plate-like fixing destination, and to fix the guide wire in a direction perpendicular to the surface. You can also.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
