  By the way, in the conventional mounting bracket, since the pair of clamping members are hinge-connected, not only the cost of equipment such as a mold for manufacturing the same is increased, but also the cost for manufacturing is increased. As a result, the product price becomes high.

  Then, this invention is made in view of the said situation, and it is a subject to provide the mounting bracket which can suppress equipment costs etc. and can suppress a product price by suppressing the manufacturing cost of a mounting bracket. To do.

The present invention has been made to solve the above-mentioned problems, and the mounting bracket according to the present invention is a mounting bracket for mounting a line-of-sight guiding body to a pipe, and a pair of clamps that clamp the pipe in its radial direction. In the mounting bracket including the clamping member, each clamping member includes an engaging portion that can be engaged with each other and a trunk portion that covers a part of the outer peripheral surface of the pipe, and the engaging portion clamps the pipe. A convex portion projecting in the pipe axial direction in the state, and a concave portion having a shape in which the convex portion can be fitted, and being juxtaposed to the convex portion along the pipe circumferential direction in the state of sandwiching the pipe. The concave portion is formed on the outer surface side of one end portion in the circumferential direction of the body portion, and the convex portion is formed so as to be separated from the one end portion in the circumferential direction in the tangential direction .

  In the mounting bracket having such a configuration, an engaging portion including a convex portion configured to protrude in the pipe axial direction and a concave portion provided in parallel with the convex portion along the pipe circumferential direction, And the other holding member, that is, the engaging part of one holding member and the engaging part of the other holding member have the same shape, so that the one and the other holding member are configured in the same shape. Can do. Therefore, a pair of clamping members can be manufactured in one hand with one mold, for example.

  And when each clamping member is made to oppose through the said pipe and it is made to approach along the said pipe axial direction, the convex part of one clamping member fits into the recessed part of the other clamping member, and also one clamping member The projecting portion of the other clamping member is fitted in the recess of the other, so that the respective engaging portions are engaged with each other, and the both clamping members are positioned with respect to each other, so that the pipe is moved in the radial direction by the both clamping members. Can be pinched.

Further, the concave portion is formed on the outer surface side of one end portion in the circumferential direction of the body portion, and the convex portion is formed so as to be separated from the one end portion in the circumferential direction in the tangential direction. When the mating parts are engaged with each other, the convex part of one clamping member is fitted into the concave part of the other clamping member and is located on the outer surface side of one end in the circumferential direction of the body part of the other clamping member, The convex part of the clamping member is fitted into the concave part of one clamping member and is located on the outer surface side of one circumferential end of the body part of the one clamping member. Then, the convex part of one clamping member abuts on one end in the circumferential direction of the body part of the other clamping member, and the convex part of the other clamping member abuts on one end part in the circumferential direction of the trunk part of one clamping member, Thereby, it can restrict | limit that the one clamping member of the engagement state and the other are trying to open apart from each other. Therefore, for example, even if both clamping members are engaged and left unattended, both the clamping members open to each other and are reliably maintained without being released, so that the workability of attachment work to the pipe is improved. improves.

  Furthermore, it is preferable that the inner surface of the convex portion is an inclined surface that is inclined so as to be on the outer side in the radial direction of the pipe in a state where the pipe is sandwiched as it is separated from one end portion in the circumferential direction.

  With this configuration, when the engaging portion of one of the holding members and the engaging portion of the other holding member are engaged along the pipe axis direction, the convex portion of each engaging portion is obstructive. As a result, the assembly work becomes easy. Also, in the engaged state, between the inclined surface of the convex portion of one clamping member and one circumferential end of the body portion of the other clamping member, and between the inclined surface of the convex portion of the other clamping member and one of the clamping members A slight gap is formed between one end portion in the circumferential direction of the body portion of the member. If it does so, the one and other clamping members of an engagement state can be opened mutually by the gap. Therefore, it is possible to obtain an appropriate clearance with respect to the pipe diameter, and to appropriately cope with variations in the pipe diameter.

A line-of-sight guidance mark according to the present invention includes a line-of-sight guidance main body and the mounting bracket according to claim 1 or 2 .

  In the line-of-sight guide mark of this configuration, since the engaging portion of one holding member and the engaging portion of the other holding member have the same shape, the one and the other holding members should be formed in the same shape. Can do. Therefore, a pair of clamping members can be manufactured in one hand with one mold, for example.

  Thus, in the mounting bracket and the line-of-sight guide according to the present invention, the convex portion configured to protrude in the pipe axial direction in the state where the pipe is sandwiched, and the pipe circumferential direction in the state where the pipe is sandwiched Since the one and the other holding members each include an engaging portion provided with a concave portion arranged in parallel with the convex portion along the first and the other holding members, the whole including the engaging portions has the same shape. For example, as a result of being able to manufacture at once by one mold, it is possible to suppress equipment costs and the like for the mold and the like, and to suppress the manufacturing cost, and accordingly The product price of the mounting bracket can be reduced.

Hereinafter, an embodiment of a mounting bracket according to the present invention and a visual guidance indicator including the mounting bracket will be described in detail with reference to the drawings.
FIG. 1 shows a line-of-sight guidance mark 1 according to this embodiment. The line-of-sight guide 1 includes, for example, a line-of-sight guiding body 2 for guiding the line of sight of a passerby and the like, and an attachment for attaching the line-of-sight guiding body 2 to a pipe P (for example, a lateral beam) such as a guard fence for a vehicle. A metal fitting 3 is provided.

  The line-of-sight guiding body 2 includes a reflecting plate 21 that reflects light from the outside, and an attachment tube portion 22 that protrudes from the peripheral edge of the reflecting plate 21.

As shown in FIGS. 2 and 3, the claw portion 56 extends from the axial direction one end portion 57 to the other end portion 58 along the axial line C <b> 1 direction of the trunk portion 5 (the length direction of the clamping member 4). A plurality of strips are provided at intervals in the circumferential direction of the body portion 5. In addition, in this embodiment, although the nail | claw part 56 is each provided in the circumferential direction one end part 51, the center part, and the other end part 52 of the trunk | drum 5, it is not restricted to this, For example, the circumferential direction of the trunk | drum 5 Only one strip may be provided in the center.

  The engaging portion 6 is provided on the outer surface 53 side of the circumferential end portion 51 of the trunk portion 5. Specifically, the engaging portion 6 has a convex portion 61 that protrudes in the direction of the axis C1 of the trunk portion 5 and a shape in which the convex portion 61 can be fitted, and the engaging portion 6 extends along the circumferential direction of the trunk portion 5. And a concave portion 62 provided in parallel with the convex portion 61. Specifically, as shown in FIG. 4, the engaging portion 6 includes one end 51 in the circumferential direction of the body 5 and the outer surface 53 of the one end 57 in the axial direction, specifically, one end in the axial direction of the contact surface 54. An extending portion 63 is extended from the side of the portion 57 in the tangential direction of the circumferential end portion 51 (width direction of the clamping member 4), and from the distal end portion of the extending portion 63 toward the axis C1 of the trunk portion 5. A convex portion 61 is provided so as to project toward the other end portion 58 side in the axial direction of the body portion 5. Here, a notch is formed on the extending portion 63 on the other end 58 side in the axial direction of the body 5 and on the one end 51 in the circumferential direction of the body 5 from the convex 61. Is a recess 62. Accordingly, the concave portion 62 is formed on the outer surface 53 side of the circumferential end portion 51 of the trunk portion 5, and the convex portion 61 extends from the circumferential end portion 51 of the trunk portion 5 in the tangential direction (the width direction of the sandwiching member 4). They are spaced apart. The convex portion 61 has a constant width from the proximal end side to the distal end side.

  Here, the concave / convex boundary surface 64 which is a boundary surface between the convex portion 61 and the concave portion 62 is a flat surface parallel to the length direction of the clamping member 4 (in the direction of the axis C1 of the body portion 5) and the height direction. In addition, it becomes a circumferential alignment surface between the clamping members 4 when the mounting bracket 3 is attached to the pipe P. In addition, both the circumferential direction one end surface 511 and the other end surface 521 of the trunk portion 5 are displaced from the concave / convex boundary surface 64 to the outside in the width direction of the clamping member 4. Further, as shown in FIG. 2, the inner surface 611 of the convex portion 61 is an inclined surface 611 that is inclined so as to be on the outer side in the radial direction of the trunk portion 5 as it is separated from the circumferential end 51 of the trunk portion 5. ing. In other words, the inclined surface 611 is inclined so as to be away from the axis C <b> 1 of the trunk portion 5 from the side closer to the circumferential end portion 51 of the trunk portion 5 to the far side. Therefore, the thickness of the convex portion 61 in the height direction of the sandwiching member 4 decreases from the side closer to the circumferential end portion 51 of the body portion 5 to the far side. The front end surface 612 of the convex portion 61 and the bottom surface 621 of the concave portion 62 are flat surfaces, and are parallel to each other, and the position in the length direction of the clamping member 4 when the mounting bracket 3 is attached to the pipe P. It becomes a mating surface.

  The insertion piece 7 is configured so that the mounting tube portion 22 of the line-of-sight guiding body 2 can be fitted, and the outer surface 53 of the other end portion 52 in the circumferential direction of the body portion 5 from the outer side in the radial direction of the body portion 5. Projected to. Specifically, as shown in FIGS. 2 and 3, the insertion piece 7 has a semi-cylindrical shape, and the outer diameter thereof corresponds to the hole diameter of the inner hole of the mounting cylinder portion 22 of the line-of-sight guiding body 2. . Further, the opposing surface 71 (surface corresponding to the cut surface of the cylinder) which is the side surface of the insertion piece 7 is sandwiched more than the uneven surface 64 so that a gap is formed between the uneven surface 64. The position of the member 4 is shifted to the outside in the width direction. Further, the opposing surface 71 has a boss 72 projecting from one end in the length direction of the clamping member 4 (one end 57 in the axial direction of the barrel 5), and the other end (the axis of the barrel 5). A boss hole 73 having a shape into which the boss portion 72 can be fitted is formed on the other end portion 58) in the direction. Note that the boss portion 72 protrudes from the facing surface 71 beyond the uneven boundary surface 64. Further, on the outer peripheral surface of the insertion piece 7, a drop prevention portion 74 having a diameter smaller than the outer diameter of other portions is formed over the entire outer peripheral surface.

  Next, the attachment of the mounting bracket 3 having a pair of the clamping members 4 having the above-described configuration to the pipe P and the attachment of the line-of-sight guiding body 2 to the pipe P will be described. When attaching the mounting bracket 3 to the pipe P, as shown in FIG. 5, one clamping member 4 is set on the pipe P so that the inner surface 55 of the trunk portion 5 is along the outer peripheral surface of the pipe P. The other clamping member 4 is set on the pipe P in the direction opposite to the one clamping member 4 on the other longitudinal end side of the one clamping member 4. In addition, since the claw part 56 projects from the inner surface 55 of the body part 5, the claw part 56 comes into contact with the peripheral surface of the pipe P. Thereby, the position shift of the mounting bracket 3 with respect to the pipe P can be effectively prevented.

  When both the clamping members 4 are moved so as to approach each other along the direction of the axis C2 of the pipe P, the convex portion 61 of one clamping member 4 is fitted into the concave portion 62 of the other clamping member 4, and the other Is located on the outer surface 53 side of one end portion 51 in the circumferential direction of the body portion 5 of the clamping member 4, and the convex portion 61 of the other clamping member 4 is fitted into the concave portion 62 of the one clamping member 4. It is located in the outer surface 53 side of the circumferential direction one end part 51 of the trunk | drum 5 of the clamping member 4, and the engaging parts 6 of both the clamping members 4 engage (refer FIG. 6 (A) and (B)). Moreover, the insertion piece 7 of one clamping member 4 and the insertion piece 7 of the other clamping member 4 are the boss | hub part currently formed in one insertion piece 7 in the state which the mutually opposing surface 71 opposes. 72 is fitted into a boss hole 73 formed in the other insertion piece 7, and a boss portion 72 formed in the other insertion piece 7 is formed in the one insertion piece 7. To be positioned. In this engagement state, the length direction of the clamping member 4 (the direction of the axis C1 of the trunk portion 5) coincides with the direction of the axis C2 of the pipe P, and the circumferential direction of the trunk portion 5 is equal to the circumferential direction of the pipe P. Moreover, the radial direction of the body portion 5 coincides with the radial direction of the pipe P.

  Here, in such an engaged state, the concave / convex boundary surface 64 of one clamping member 4 and the concave / convex boundary surface 64 of the other clamping member 4 are in contact with each other, thereby positioning the clamping member 4 in the circumferential direction. ing. Further, the front end surface 612 of the convex portion 61 of one clamping member 4 and the bottom surface 621 of the concave portion 62 of the other clamping member 4 are in contact with each other, and the bottom surface 621 of the concave portion 62 of one clamping member 4 and the other The front end surface 612 of the convex portion 61 of the clamping member 4 is in contact. Thereby, positioning of the holding member 4 in the length direction is performed.

  Further, a gap is formed between the inclined surface 611 (the inner surface of the convex portion 61) of the one or other clamping member 4 and the contact surface 54 of the other or one clamping member 4. For this reason, one and the other clamping members 4 can be opened in the width direction starting from the concave / convex boundary surface 64 as much as the gap. That is, the state where the gap is formed between the inclined surface 611 and the contact surface 54 (FIG. 6A) changes to the state where the inclined surface 611 and the contact surface 54 are in contact (FIG. 7). Until both the sandwiching members 4 are opened so that the insertion pieces 7 are separated from each other, the inner surface 55 of the body portion 5 of one sandwiching member 4 and the inner surface 55 of the body portion 5 of the other sandwiching member 4 are formed. The diameter of the hole formed can be increased. When the inclined surface 611 and the contact surface 54 come into contact with each other, the further opening of the holding member 4 is restricted, and even if the mounting bracket 3 is left as it is, both the holding members 4 open to each other. The engaged state is maintained without being disengaged and falling off the pipe P. Therefore, it is possible to obtain an appropriate clearance with respect to the diameter of the pipe P while restricting the opening of the clamping member 4 within a predetermined range, and it is possible to improve the efficiency of the mounting work and appropriately cope with variations in the diameter of the pipe P. it can.

  And in the state shown to FIG. 6 (A), the insertion pieces 7 of one and the other clamping member 4 are fastened with a volt | bolt etc., for example. Here, since a gap is formed as a fastening allowance between the opposing surface 71 of one clamping member 4 and the opposing surface 71 of the other clamping member 4, it can be firmly tightened using this. it can. Thereby, the attachment fitting 3 is attached to the pipe P. It is not always necessary to tighten with bolts.

  And in both the insertion piece 7 of one clamping member 4 and the insertion piece 7 of the other clamping member 4 which are positioned by the fitting of the boss portion 72 and the boss hole 73 and are cylindrical, The mounting tube portion 22 of the line-of-sight guiding body 2 is fitted and screwed from the side surface of the mounting tube portion 22. Here, since the outer surface 53 of the insertion piece 7 is provided with the removal prevention portion 74, the line-of-sight guiding body 2 does not come out of the insertion piece 7 inadvertently or inadvertently. In this way, the line-of-sight guiding body 2 is attached to the pipe P as shown in FIGS.

  In the mounting bracket 3 and the line-of-sight guide 1 configured as described above, the engaging portion 6 of one holding member 4 and the engaging portion 6 of the other holding member 4 are both convex portions 61 and concave portions 62. Since it is the same shape provided, one and the other clamping member 4 can be comprised by the same shape. Therefore, as a result of being able to manufacture a pair of clamping members 4 with a single mold, for example, it is possible to suppress equipment costs and the like on the mold and the like, and to suppress the manufacturing cost of the mounting bracket 3. Therefore, the product price of the mounting bracket 3 can be suppressed.

  In the present embodiment, the case where the reflecting plate 21 of the line-of-sight guiding body 2 is configured to reflect light from the outside only on one side has been described. Thus, the case where it is comprised so that the reflecting plate 21 can reflect light in the both surfaces may be sufficient.

  Moreover, although this embodiment demonstrated the case where the engaging part 6 was comprised by a pair of convex part 61 and the recessed part 62, it is not restricted to this, For example, as shown in FIG. 61 and the plurality of recesses 62 may be arranged alternately along the circumferential direction of the body portion 5.

  Furthermore, in the present embodiment, the case where the convex portion 61 has a constant width from the proximal end side to the distal end side has been described. However, the present invention is not limited to this, and as shown in FIG. It may be the case. In this case, the uneven boundary surface 64 is inclined with respect to the length direction of the sandwiching member 4.

  Furthermore, in the present embodiment, the case where the claw portion 56 is continuously provided so as to extend from the one end portion 57 in the axial direction of the trunk portion 5 to the other end portion 58 has been described. 5 may be provided intermittently from one axial end portion 57 to the other end portion 58.
