JP 2003-348739 A

FIG. 14 is a view showing the structure of the support of Patent Document 1. As shown in FIG.
As shown in FIG. 14, the fixing portion 4 of the support 3 has a vertically long rectangular flat plate-like base portion 4a and two hook portions 4b and 4c projecting up and down on one surface side of the base portion 4a. ing.

  The upper hook portion 4b can receive an intermediate portion of the suspension bolt to be attached from one side (left side in the drawing) with respect to the axis L along the longitudinal direction (vertical direction) of the base portion 4a. Thus, it is formed in a semi-cylindrical shape whose left side is opened.

  The lower hook portion 4c is provided at a position separated from the upper hook portion 4b by an outer diameter of the suspension bolt or more, and is attached to the axis L from the other side (right side in the drawing). It is formed in a semi-cylindrical shape with an opening on the right side so that an intermediate part of the suspension bolt can be received.

  The inner circumferences of the two hook portions 4b and 4c are concentric with the axis L, and the inner diameter is set slightly smaller than the outer diameter of the suspension bolt to be attached.

  On the other hand, a support portion 5 for supporting a cable or the like is provided on the opposite surface side of the base portion 4a. The support portion 5 has a belt-like substrate 5a that is in contact with the opposite surface side of the base portion 4a, and a shaft hole that protrudes from the center portion of the substrate 5a and is provided at the center of the base portion 4a of the fixing portion 4. It has a shaft 5b inserted non-returnably on 4d, and a plurality of support pieces 5c erected in parallel on the opposite surface side of the substrate 5a, and is centered on the shaft 5b with respect to the fixed portion 4. It can be turned.

  In the support 3 having such a structure, as shown in FIG. 15A, the suspension bolt 1 passes between the upper and lower hook portions 4b and 4c, and the outer peripheral portion thereof abuts on one surface side of the base portion 4a. And the suspension bolt 1 enters the open side portions of the hook portions 4b and 4c, respectively, and pushes both the hook portions 4b and 4c when they are rotated in a predetermined direction (counterclockwise in FIG. 15). As shown in FIG. 15B, the suspension bolt 1 is inscribed in the hook portions 4b and 4c.

  As a result, the support 3 is rotatably attached to the suspension bolt 1 and, as shown in FIG. 16, after setting the support portion 5 to have an appropriate orientation, the support 3 is interposed between the plurality of support pieces 5c. A long object 2 such as a cable is inserted and supported.

  However, as described above, in the support tool 3 having a structure that is attached to the suspension bolt only by engagement between the two hook portions 4b and 4c that are vertically separated and opposite to each other and the suspension bolt 1, the long length that is supported is supported. For example, when the object 2 is pulled in the direction of arrow A in FIG. 16, a rotational force in the direction opposite to that at the time of attachment is generated with respect to the fixing portion 4, and the hook portions 4b and 4c are engaged with the suspension bolt 1 as shown in FIG. There was a problem that the joint 3 was released and the support 3 was dropped.

  As a method for preventing this, it is conceivable to reduce the elasticity of both the hook portions 4b and 4c or to reduce the opening width of the side portions. However, this requires a strong rotational force at the time of attachment, and the attachment work is difficult. Become.

  An object of the present invention is to solve this problem, and to provide a long object support that is easy to attach to a rod-shaped body such as a suspension bolt, and that does not easily fall off due to pulling of a supported long object. Yes.

  Since it comprised as mentioned above, in the elongate object support tool of this invention, it can attach to a rod-shaped body by the same simple rotation operation as before, and also the 3rd engaging part at the time of the attachment becomes a rod-shaped body. Since it engages reversely and prevents rotation in the direction opposite to the rotation direction at the time of attachment, even if a long object supported by the long object support part is pulled, There is no fear that the support is disengaged.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a structure of a long object support 20 (hereinafter simply referred to as a support 20) according to an embodiment of the present invention.

  The support 20 is integrally formed of a synthetic resin, and the base 21 is formed in a vertically long band shape. On the one surface 21a side of the base portion 21, a first engaging portion 22 and a second engaging portion 23 for engaging with the above-described suspension bolt as a rod-like body to be attached are in the longitudinal direction of the base portion 21 (in the drawing, It protrudes in a state of being separated in the vertical direction).

  The first engaging portion 22 on the upper side has an inner peripheral shape corresponding to the outer peripheral shape (cylindrical shape) of the suspension bolt to be attached, and an axial line L (in the longitudinal direction on the one surface 21a side of the base portion 21). It is formed in a substantially semi-cylindrical shape that receives an intermediate portion of the suspension bolt 1 from one side (the left side in FIG. 1) of the phantom line and circumscribes the suspension bolt 1.

  The second engaging portion 23 on the lower side is formed symmetrically with the first engaging portion 22 with respect to the axis L at a position spaced from the first engaging portion 22 by at least the thickness of the suspension bolt 1. Yes. That is, it has an inner peripheral shape corresponding to the outer peripheral shape (cylindrical shape) of the suspension bolt 1, and receives the intermediate portion of the suspension bolt 1 from the other side of the axis L (the right side in FIG. 1) to make circumscribing engagement. It is formed in a semi-cylindrical shape.

  The inner circumferences of the first engagement portion 22 and the second engagement portion 23 are concentric with the axis L, and the inner circumference diameter is set slightly smaller than the outer circumference diameter of the suspension bolt 1, and the axis L is the center. The central angle of the inner periphery is formed so as to slightly exceed 180 °.

  Further, on the back side of the inner peripheral walls 22a and 23a of the first engaging portion 22 and the second engaging portion 23, screw threads 25 and 26 that are screwed into screw grooves formed on the outer periphery of the suspension bolt are provided. Each is formed.

  A third engagement portion 30 is provided at an end of the base 21 opposite to the second engagement portion 23 with respect to the first engagement portion 22, that is, at the upper end of the base 21 in FIGS. Is provided.

  The third engagement portion 30 is formed thinner than the base portion 21 so as to be easily elastically deformed, extends upward with substantially the same width from the upper end portion of the base portion 21, and receives the force from the one surface 21 a side of the base portion 21 to receive the base portion 21. A tilting piece 31 inclined to the opposite surface 21b side, and a protrusion 32 protruding from one side 31a of the tilting piece 31 on one side of the axis L (left side in this example).

  The outer wall surface 32a opposite to the axis L of the protrusion 32 is so high that the height from the tilting piece 31 is upward (away from the first engaging portion 22) and so that it is close to the axis L. The inner wall surface 32 b on the axis L side is formed to be orthogonal to the tilting piece 31. On the inner wall surface 32b of the protrusion 32, a thread 33 is formed to be screwed into the thread groove of the suspension bolt.

  In addition, since the portion of the tilting piece 31 whose thickness is increased by the protrusion 32 is high in rigidity and does not elastically deform, the center of tilting by the force received through the protrusion 32 is in the vicinity of the edge on the base 21 side. The portion is inclined to the opposite surface 21b side of the base portion 21 as a hinge portion.

  On the other hand, on the opposite surface 21b side of the base portion 21, a long object support portion 40 for receiving and supporting a long object such as a cable or a tube is provided.

  The long object support portion 40 extends from one end side (lower end side) of the opposite surface 21 b of the base portion 21 in a direction away from the base portion 21, and extends to the other end side (upper end side) of the opposite surface 21 b of the base portion 21. It is formed in an annular shape so as to return to an adjacent position, and at least its tip is formed so as to be elastically deformable inward.

  More specifically, the long object support portion 40 of this embodiment has a substantially the same width and the same thickness as the base portion 21, and extends linearly downward from a position slightly above the lower end of the opposite surface 21b of the base portion 21. An inclined piece 41, a bottom piece 42 that is folded back from the tip of the inclined piece 41 and is continuous with the lower end of the opposite surface 21 b of the base portion 21 to form a laterally triangular tubular high-rigidity reinforcing portion, A semi-cylindrical piece 43 extending in a semicircular shape from the tip to a position close to the upper portion of the opposite surface 21 b of the base 21, and a narrower and thinner width than the semi-cylindrical piece 43. It has a tongue piece 44 bent asymptotically to the upper part of the opposite surface 21b and elastically deformed inward by receiving a force from the outside.

  The tongue 44 is pushed inward and elastically deformed to widen a gap with the base 21 to facilitate the reception of a long object to be supported, and is pushed outward to be elastically deformed and elastically deformed. Narrow the gap between and prevent the removal of the long items you received.

  Further, a reinforcing rib 45 for preventing the opening of the semi-cylindrical piece 43 due to the weight of the received long object is formed at the center of the outer periphery of the semi-cylindrical piece 43 so as to be continuous with the bottom piece 42.

  Further, the triangular columnar hole formed surrounded by the inclined piece 41, the bottom piece 42, and the lower portion of the base portion 21 is divided into left and right by a partition plate 46 erected at the center thereof.

Next, a method of using the support 20 having the above configuration will be described.
First, as shown in FIG. 5, the support 20 is turned sideways, and the base portion until the intermediate portion of the suspension bolt 1 to be attached passes through the gap between the first engagement portion 22 and the second engagement portion 23. 21 is rotated in the direction in which the opened side portions of the first engaging portion 22 and the second engaging portion 23 approach the outer peripheral portion of the suspension bolt 1 (counterclockwise in FIG. 5). Move.

  By this rotation, the suspension bolt 1 enters the inside of the first engagement portion 22 and the second engagement portion 23 so as to slightly open, and the outer periphery of the suspension bolt 1 is the first as shown in FIG. 3 is in contact with the lower end of the outer periphery of the protrusion 32 of the engaging portion 30.

  When the support 20 is further rotated, a pressing force is generated on the tilting piece 31 to the opposite surface 21b side of the tilting piece 31 through the protrusion 32 that is in contact with the outer periphery of the suspension bolt 1, and the tilting piece 31 that receives this pressing force is generated. However, it inclines toward the opposite surface 21b side of the base 21 as shown in FIG.

  As described above, since the height of the protrusion 32 increases toward the upper side, the inclination of the tilting piece 31 increases as the support tool 20 rotates, and the upper end of the protrusion 32 has a suspension bolt as shown in FIG. When it comes into contact with the outer periphery of 1, the inclination becomes maximum.

  And the support tool 20 is further rotated from the state of FIG. 8, and the suspension bolt 1 has completely entered the inside of the first engaging portion 22 and the second engaging portion 23 as shown in FIG. Then, the suspension bolt 1 reaches the right side position of the protrusion 32 of the third engagement portion 30, and the contact between the outer periphery of the suspension bolt 1 and the tip of the protrusion 32 is released.

  For this reason, there is no pressing force on the third engaging portion 30, and the tilting piece 31 is rotated toward the one surface 21 a side of the base portion 21 by the elastic restoring force, and is returned to the same state as the base portion 21. The inner wall surface 32b and the outer peripheral surface of the suspension bolt 1 are substantially in contact with each other.

  In this state, the support 20 is engaged and attached to the suspension bolt 1 with three locations along the vertical direction alternately sandwiched from opposite directions.

  Further, in this attached state, the screw threads 25, 26, 33 of the first engagement portion 22, the second engagement portion 23, and the third engagement portion 30 are thread grooves (not shown) of the suspension bolt 1. Screw).

  Therefore, the mounting height position can be adjusted by rotating the support 20 around the suspension bolt 1.

  Thus, after attaching the support tool 20 to the suspension bolt 1 and adjusting a height position, as shown to (a) of FIG. 10, the long thing 2 to be supported, such as a cable and piping, is made into a long part. When the tongue piece 44 of the support portion 40 is pushed in from above, the tongue piece 44 is elastically deformed inward as shown in FIG. 10B, and the gap between the opposite surface 21b of the base portion 21 is widened and the long object 2 Is guided inside the long portion support portion 40, and the long object 2 is supported in a state of crossing the suspension bolt 1.

  Here, for example, as shown in FIG. 11, when the long object 2 supported by the long portion support portion 40 is pulled in the longitudinal direction A, the rotation direction when the support tool 20 is attached to the suspension bolt 1. Although the force to rotate in the opposite direction is applied, the support 20 is alternately arranged at three locations along the vertical direction with respect to the suspension bolt 1 by the three engaging portions 22, 23, 30 arranged vertically. The third engaging portion 30 is engaged with the suspension bolt 1 in a non-returning manner. Therefore, there is no possibility that the engagement of the support 20 with the suspension bolt 1 is released by the force received from the long object 2.

  Further, when the support 20 is removed from the suspension bolt 1, the third engagement portion 30 is pushed (or pulled) toward the opposite surface 21b of the base portion 21 as shown in FIG. The engagement state of the third engagement portion 30 with respect to the suspension bolt 1 is released without protruding from the one surface 21 a of the base portion 21.

  Then, from this state, the support 20 is rotated in the direction opposite to that at the time of attachment, so that the state shown in FIG. 6 is obtained and the suspension bolt 1 and the first engagement portion 22 and the second engagement are further rotated. If the engagement with the joint portion 23 is released to the state shown in FIG. 5, the support 20 can be detached from the suspension bolt 1.

  The long object support portion 40 of the support tool 20 of this embodiment has a surface support structure that supports the long object 2 on the flat inner peripheral surface of the strip-shaped semi-cylindrical piece 43. Since there is no fear that the long object 2 will come off without binding with a nylon band or the like, the long object 2 can be supported without being strongly pressed.

  Further, since there is no need for binding, the force when the long object 2 is pulled is not easily transmitted to the support 20, and even if it is transmitted, it is engaged by the third engaging portion 30 as described above. Since the rotation in the direction to release the is prevented, there will be no detachment accident.

  Further, as described above, the connecting portion of the long object support portion 40 to the base portion 21 is reinforced in the shape of a laterally triangular column, and the semi-cylindrical piece 43 is also reinforced by the reinforcing ribs 45. A long object can be stably supported.

  In addition, in the support tool 20 of the said embodiment, the 3rd engaging part 30 was provided in the upper end side of the base 21 in the attachment state, However, the base part in the attachment state was reversed by making the up-and-down relation of three engagement parts reverse. A third engagement portion 30 may be provided on the lower end side of the 21.

  Moreover, in the support tool 20 of the said embodiment, although the screw thread screwed together in the thread groove of the suspension bolt 1 was each provided in the 1st-3rd engaging parts 22, 23, and 30 each, The present invention is not limited, and if the number of threads of each engaging portion is increased, the downward movement due to the weight of the long object to be supported can be prevented more strongly, and the heavy long object can be supported. Can be performed stably.

  In addition, in order to enable adjustment of the mounting height position of the support 20 with respect to the suspension bolt 1 and to prevent downward movement due to the weight of the long object to be supported, at least one inner wall of the three engaging portions It is sufficient to provide a screw thread.

  As shown in FIG. 13, if the partition plate 46 is provided with a through hole 50 through which the binding band can be inserted, the binding band can be used together.

  Further, the structure of the long object support portion 40 is not limited to the structure of the above embodiment. For example, the overall outer shape of the long object support portion 40 may be changed from the above-described cylindrical shape to a rectangular tube shape, and various modifications are possible.
