The attachment body 110 has a front surface 110a disposed so as to face outward of the columnar body P, and a back surface 110b on the opposite side.

  The attachment body 111 has a flat overall shape, its front view outline (contour) has a substantially rectangular shape, and its plan view outline and side view outline have a substantially I shape. . More specifically, the attachment body 111 includes a short side arranged along the width direction of the belt-like body 120 (vertical direction in FIG. 3B) in the front view, and the longitudinal direction of the belt-like body 120 (see FIG. 3 (b) in the horizontal direction). The attachment body 111 is gently curved so that the substantially center is recessed in plan view, and both ends thereof are semicircular. Further, the attachment body main body 111 extends linearly in a side view, but the width of the upper and lower ends is larger than the width of the center. The attachment body 111 is formed of a synthetic resin, but the material thereof can be arbitrarily selected by those skilled in the art, and may be formed of, for example, a metal material.

  A pair of insertion parts 113 are formed in the meat part of the attachment body 111. A pair of insertion part 113 is arranged along the long side direction on both sides of the through-hole 115 of the attachment body main body 111 center. The insertion portion 113 is a slit extending in the short side direction (width direction), and is configured to be able to insert the flat belt-like body 120. The band-shaped body 120 can pass through both of the pair of insertion sections 113, and the two insertion sections 113 are arranged along the longitudinal direction of the band-shaped body 120.

  The through hole 115 functions as a holding portion for holding the fixing member 150. In other words, the through-hole 115 is a round hole through which the shaft portion 151 of the fixing member 150 can be inserted and whose passage through the head portion 152 is restricted. A recess 116 is formed in the periphery of the through hole 115 on the back surface 110b of the attachment body 110 on the columnar body P side. The recess 116 has a hexagonal shape when viewed from the back, and is configured to be able to fit at least a part of the hexagonal head 152 of the bolt-shaped fixing member 150. In other words, the inner surface of the recess 116 is provided with a rotation restricting portion that engages with the head 152 and restricts the rotation of the fixing member 150.

  Further, in order to come into contact with the belt-like body 120 passing through the insertion hole 113, a protruding portion 117 is formed to protrude in each insertion portion 113. The projecting portion 117 is a projecting piece projecting in a direction (the other end side) away from the center side (one end side) of the attachment body 111 on the inner peripheral edge of the insertion portion 113. In other words, each protrusion 117 extends from the inside to the outside of the attachment body 111 along the longitudinal direction of the strip 120. That is, the pair of protrusions 117 extend in a direction away from each other. The proximal end of the protruding portion 117 is integrated with the inner peripheral edge of the insertion portion 113, and the protruding portion 117 is tapered from the proximal end toward the distal end. Further, the distal end of the projecting portion 117 extends substantially linearly along the width direction, and a notch is formed on the proximal end side at substantially the center thereof as if forming two trapezoidal teeth. In other words, the protrusion 117 is composed of two protrusions. As will be described later, the front end surface of the protruding portion 117 is configured to be able to contact the outer surface of the belt-shaped body 120.

  Further, a cylindrical portion 118 having a circular shape in cross section is formed at both ends in the long side direction of the attachment body 111 so as to face the tip of the protruding portion 117. The cylindrical portion 118 constitutes a part of the inner peripheral edge of the insertion portion 113. Then, the belt-like body 120 is inserted into the gap between the tip of the protruding portion 117 and the curved surface of the cylindrical portion 118. This gap is substantially equal to the thickness of the strip 120. More specifically, the tip of the protruding portion 117 is configured to abut on the flat portion 121 of the strip 120, and the curved surface of the column portion 118 is configured to abut on the raised portion 122 of the strip 120. That is, the protrusion 117 and the column part 118 cooperate to function as a contact part. Further, the gap is substantially equal to the sum of the thickness of the flat portion 121 of the belt-like body 120 and the raised height of one raised portion 122. This prevents the belt-like body 120 from being twisted in the insertion part 113.

  As shown in FIG. 4, the belt-like body 120 of the present embodiment is a thin and flat long body. The belt-like body 120 is wound around the columnar body P in a state of being inserted into the pair of insertion portions 113 of the attachment body 110, thereby binding the attachment body 110 to the columnar body P and fixing the fixing member 150. Functions to hold. The strip 120 includes a flat portion 121 having a predetermined width and a raised portion 122 that protrudes on both sides in the width direction of the flat portion 121 in a cross-sectional view. The belt-shaped body 120 has a predetermined rigidity (hardness) and elasticity, and maintains a tight arch (arc) shape without dripping down due to gravity when bent and deformed in the longitudinal direction. Is possible. In addition, the strip 120 is assumed to be wound around a columnar body P such as a utility pole outdoors, and preferably has a predetermined strength and weather resistance. In addition, in this embodiment, although the strip | belt shaped object 120 consists of synthetic resins, other materials, such as a metal wire, may be selected.

  The fastener 130 of the present embodiment is used to fasten both end sides of the belt-like body 120 and form a closed annular portion so as to surround the outer periphery of the columnar body P. As shown in FIG. 5A, the fastener 130 includes a housing-like fastener body 131 and a pair of fixing holes 132 formed in the fastener body 131. Each fixing hole 132 is configured to have a shape that allows the band-shaped body 120 to be inserted, and the end of the band-shaped body 120 is inserted into each fixing hole 132. In the fixing hole 132, an insertion port 132a of the strip 120 is defined. Further, as shown in FIG. 5B, a lock claw 133 extending in an oblique direction is provided in each fixing hole 132 so that a pointed tip is separated from the insertion port 132a. The lock claw 133 is elastically deformed up and down like a leaf spring. When the end of the band 120 is inserted from the insertion port 132a of the fixing hole 132, the movement of the band 120 in the forward (advance) direction is allowed, but the movement in the reverse (withdrawal) direction is restricted. . More specifically, when the strip 120 is directed in the forward direction, the lock claw 133 is pushed down, and the strip 120 can advance in the fixing hole 132. On the other hand, when the strip 120 moves in the opposite direction, the tip of the lock claw 133 bites into the outer surface of the strip 120 and locks the strip 120.

  Next, with reference to FIG.6 and FIG.7, the installation structure 10 in which the support apparatus 100 of this embodiment was attached to the columnar body P which is an electric pole is demonstrated. FIG. 6 is a cross-sectional view of the installation structure 10 of the support device 100. Fig.7 (a) is the elements on larger scale of the attachment structure 110 vicinity of the installation structure 10 of FIG. 6, FIG.7 (b) is the DD sectional drawing.

  As shown in FIG. 6, in the installation structure 10 of the present embodiment, both ends of the belt-shaped body 120 are fastened by the fasteners 130 in a state where the belt-shaped body 120 is tightly wound around the outer periphery of the columnar body P. The belt-shaped body 120 is deformed according to the outer diameter of the columnar body P and is tightly wound around the columnar body P, and is stretched between the members in a tensioned state without being loosened. In the present embodiment, the two attachment bodies 110 are fixed to the columnar body P by the strip 120. That is, the support device 100 may include a plurality of attachment bodies 110 according to the diameter of the columnar body P, the number of attachment objects, and the like. In each attachment body 110, the shaft portion 151 of the fixing member 150 protrudes outward from the columnar body P, and an attachment object (not shown) can be fixed to the shaft portion 151. The attachment object is, for example, a wiring box, a cable suspension, and the like, and is a concept including all objects attached to the columnar body P using a fixing member (bolt shaft in the present embodiment).

  More specifically, as shown in FIG. 7A, the attachment body 110 is fixed by the belt-like body 120 so that the back surface 110 b in which the recess 116 of the attachment body 110 is formed faces the outer surface of the columnar body P. . The belt-like body 120 passes through the outside of the cylindrical portion 118 at both ends of the attachment body 110 and is bent so as to be wound around the cylindrical portion 118 from the outside of the columnar body P. The band 120 passes through the pair of insertion portions 113 from the surface 110a side of the attachment body 110 and extends between the back surface 110b and the outer surface of the columnar body P at the approximate center of the attachment body 110. Since the belt-like body 120 is in a tension state, the back surface 110b of the attachment body 110 is urged toward the outer surface of the columnar body P. In particular, the cylindrical portions 118 at both ends of the attachment body 110 are pulled toward the columnar body P side by the belt-shaped body 120. At this time, since the belt-like body 120 is bent along the curved surface portion of the cylindrical portion 118 (inner peripheral edge of the insertion portion), the contact portion of the belt-like body 120 is prevented from being damaged and the adhesion between the attachment body 110 and the belt-like body 120 is prevented. Increases and enables more stable fixation.

  In addition, the shaft portion 151 of the fixing member 150 penetrates the through hole 115 of the attachment body 110 from the back surface 110b side, and a part of the head portion 152 is accommodated in the recess 116, and the shaft portion 151 of the fixing member 150 is It protrudes from the surface 110 a of the attachment body 110 through the through hole 115. That is, the fixing portion (shaft portion 151) of the fixing member 150 is erected so as to face the outside of the columnar body P. The belt-shaped body 120 passes outside the head 152 of the fixing member 150 and is in contact with the outer surface of the head 152. At this time, since the belt-like body 120 is stretched in a tension state, the head 152 of the fixing member 150 is biased against the attachment body 111 by the tension. That is, when the belt-like body 120 passes between the base end portion (head 152) of the fixing member 150 and the columnar body P, the head 152 is sandwiched between the attachment body 110 and the belt-like body 120. That is, in the installation structure 10 of the present embodiment, the attachment body 120 is pressed and fixed to the columnar body P by the winding of the belt-shaped body 120, and the attachment body 120 forms a columnar shape on the head 152 of the fixing member 150. Press toward the body P. The inner surface of the belt-shaped body 120 abuts on the outer surface of the columnar body P, and the attachment body 110 is held away from the outer surface of the columnar body P with the belt-shaped body 120 and the head 152 of the fixing member 150 being separated. As a result, the fixing member 150 is attracted to the columnar body P and stands upright with the belt-shaped body 120 interposed between the head 152 of the fixing member 150 and the outer surface of the columnar body P.

  The pressing force (or pinching force) by the strip 120 restricts the shaft portion 151 of the fixing member 150 from loosening or withdrawing from the through hole 115. Further, the corner of the hexagonal head 152 is engaged with the corner of the inner surface of the hexagonal recess 116 (rotation restricting portion 116a), and the head 152 is restricted from rotating in the recess 116. . As a result, the fixing member 150 is stably held by the attachment body 110 and the belt-shaped body 120.

  FIG. 7B is a cross-sectional view of FIG. As shown in FIG. 7B, the tip of the protruding portion 117 is in contact with the inner surface of the flat portion 121 of the strip 120 inserted through the insertion portion 113. On the other hand, the curved surface portion (the inner peripheral edge of the insertion portion 113) of the cylindrical portion 118 is in contact with the outer surface of the raised portion 121 of the strip 120. That is, the belt-like body 120 abuts on three points in the insertion portion 113 of the attachment body 110 and is held between the protrusion 117 and the column portion 118.

  Next, a method for constructing the installation structure 10 will be described with reference to FIGS.

  First, a strip 120 having a length that can surround the columnar body P (electric pole in this embodiment), and one or a plurality (two in this embodiment) of attachments 110 and fixing members 150 depending on the number of attachment objects. And one fastener 130 are prepared.

  Next, as shown in FIG. 8A, the tip of the belt-like body 120 is inserted into the insertion portion 113 of the attachment body 110 from the surface 110 a side, and the shaft portion 151 of the fixing member 150 is attached to the through-hole of the attachment body 110. 115 is inserted from the back surface 110b side. At this time, the belt-shaped body 120 is held in the insertion portion 113 while being in contact with the contact portions 117 and 118, and the belt-shaped body 120 is restricted from moving in the insertion portion 113 only by the weight of the attachment body 110. ing.

  More specifically, the belt-like body 120 is sandwiched between the distal end of the protruding portion 117 and the curved portion of the cylindrical portion 118 in the insertion portion 113. Then, when the protruding portion 117 and the belt-like body 120 come into contact (contact), a frictional force is generated between the tip end surface of the protruding portion 117 and the outer surface of the flat portion 121 of the belt-like body 120. Similarly, the raised portion 122 of the belt-shaped body 120 abuts on the cylindrical portion 118, and a frictional force is generated therebetween. However, since the contact area of the protrusion 117 is larger, the former frictional force is larger. Since the static frictional force with the contact portion is larger than the gravity acting on the attachment body 110 and / or the belt-like body 120, the sliding is restricted only by the weight of the attachment body 110 and / or the belt-like body 120. . That is, even when the hand is released from the attachment body 110 or the hand is released from the belt-like body 120 during the attachment work to the columnar body P, the attachment body 110 and the belt-like body 120 are inserted into the insertion portion 113. It is maintained on the spot without slipping through. That is, the belt-shaped body 120 is temporarily held, so that one hand of the operator is free at the time of work, and either the attachment body 110 or the belt-shaped body 120 is gripped by one hand and the fixing member is gripped by the other hand. 150 can be easily inserted into the through hole 115 of the attachment body 110.

  In the present embodiment, the static friction force by the contact portion is larger than the gravity acting on the attachment body 110 and larger than the gravity acting on the belt-like body 120, and therefore, the hands are released from any member. Even the other member is held. However, when the weight of the attachment body 110 is very large, the static friction force may be smaller than the gravity acting on the attachment body 110 and larger than the gravity acting on the belt-like body 120. Alternatively, when the strip 120 is long and heavy, the static friction force may be smaller than the gravity acting on the strip 120 and larger than the gravity acting on the attachment body 110. This static frictional force is arbitrarily determined by the strength with which the contact portions 117 and 118 hit the belt-like body 120. When this contact is strong, the static frictional force becomes large and a heavy member can be temporarily held, but a strong force is required for the sliding operation within the insertion portion 113 of the belt-shaped body 120. That is, the weight that can be temporarily held and the sliding operation feeling are in a trade-off relationship. Therefore, when the weight difference between the two members is large, a better sliding operation feeling can be obtained by adjusting the strength of the contact portion so that only the lighter one can be temporarily held. .

  Subsequently, the strip 120 is pulled out to the back surface 110 b side of the attachment 110 so that the strip 120 passes through the outside of the head 152 of the fixing member 150 disposed in the through hole 115. At this time, the belt-like body 120 slides in the insertion portion 113 in a state where it is in contact with the protruding portion 117 and the column portion 118 (contact portion). That is, when the operator pulls the strip 120 with a predetermined force exceeding the static friction force, the strip 120 slides smoothly in the insertion portion 113 (in both directions along the longitudinal direction) against the friction force. Is possible.

  And as shown in FIG.8 (b), the edge part of the strip | belt-shaped body 120 pulled out from one insertion part 113 is inserted into the other insertion part 113 from the back surface 110b. At this time, a closed ring is formed between the attachment body main body 111 and the belt-like body 120, and the head 152 of the fixing member 150 is disposed therein. Thereby, it is possible to prevent the fixing member 150 from falling out of the through hole 115. In particular, since the belt-like body 120 has predetermined rigidity and elasticity, an arch shape stretched between the pair of insertion portions 113 as shown in FIG. 8B is maintained. Therefore, even if the head 152 is lifted so that the fixing member 150 comes out of the through-hole 115, the inner surface of the band-like body 120 is suppressed in the head 152, and the shaft portion 152 is prevented from being completely detached from the through-hole 115. Can do. In the pair of insertion portions 113, the protruding portions 117 protrude in opposite directions (outside along the longitudinal direction of the band-shaped body 120), so that the insertion positions are separated from each other and the band-shaped body 120 is gently bent. Thus, the strip 120 can be easily inserted into the insertion part 113.

  Further, as shown in FIG. 8C, the belt-like body 120 is pulled out from the insertion portion 113 to the surface 100a side by a predetermined length, and is tightened so that the outer surface of the belt-like body 120 contacts the head 152 of the fixing member 150. Thus, the fixing member 150 can be integrally held on the attachment body 110. By performing the same operation also on another attachment body 110, a plurality of attachment bodies 110 and a fixing member 150 can be integrally assembled to one belt-like body 120 as the support device 100. That is, in the support device 100, the head portion 152 of the fixing member 150 is sandwiched and temporarily held by the attachment body 110 and the belt-shaped body 120 in the arrangement configuration before the belt-shaped body 120 is wound around the columnar body P. The shaft portion 151 of the fixing member 150 is erected on one side of the body 120 (that is, the outer surface of the columnar body P).

  Next, the support device 100 (the belt-like body 120 holding the attachment body 110 and the fixing member 150) having the above arrangement configuration is wound around the outer periphery of the columnar body P, and both end portions thereof can be the fixing holes 132 of the fastener 130. Insert as long as possible. Thereby, the belt-like body 120 can be fastened in a tensioned state so that the attachment body 110 is pressed against the columnar body P and the fixing member 150 is attracted to the attachment body 110. As a result, the shaft portion 151 of the fixing member 150 protrudes or stands outward, and the support device 100 can be attached to the columnar body P.

  Hereinafter, the effect in the support apparatus 100 (attachment body 110) of one Embodiment which concerns on this invention is demonstrated.

  According to the support device 100 of the present embodiment, the fixing member 150 is disposed in the through hole 115 of the attachment body 110 and the belt-like body 120 is passed through the pair of insertion portions 113 of the attachment body 110 so that the belt-like body 120 is columnar. By winding around the body P and fastening with the fastener 130, the attachment body 110 can be tightly bound to the columnar body P and the shaft portion 151 of the fixing member 110 can protrude outward from the columnar body P. That is, in the support device 100 of the present embodiment, by using the belt-like body 120 that is deformable in the longitudinal direction, the belt-like body 120 can be deformed corresponding to the columnar bodies P having various diameters or shapes. Therefore, the support device 100 can stably support the object to be supported by the fixing member 150 regardless of the diameter or shape of the columnar body.

  Further, according to the support device 100 of the present embodiment, the band 120 passes through the outside of the head 152 of the fixing member 150, and the head 152 is sandwiched between the band 120 and the attachment body 111. . That is, the belt-shaped body 120 presses and fixes the attachment body 110 to the columnar body P and simultaneously presses the head portion 152 of the fixing member 150 against the attachment body main body 111. As a result, the head 152 of the fixing member 150 is drawn toward the columnar body P. Thereby, the attitude | position which protruded the axial part 151 of the fixing member 150 to the outward of the columnar body P can be maintained easily and stably. In addition, since the head 152 of the fixing member 150 is disposed inside the ring formed by the belt-like body 120 and the attachment body 110 during or after the attachment of the support device 100, the fixing member 150 is attached. It is possible to prevent the body 110 from falling out of the through hole 115. Further, the belt-like body 120 is interposed between the head portion 152 of the fixing member 150 and the columnar body P, so that the head portion 152 of the fixing member 150 and the attachment body main body 111 are in direct contact with the outer surface of the columnar body P. Absent. Thereby, when the support apparatus 100 is attached to the columnar body P, it is possible to prevent the outer surface of the columnar body P from being damaged.
