Abstract
Description
[Technical Field]
[0001] The present invention relates to a holder for wiring and piping material that holds wiring and piping material. [Background technology]
[0002] BACKGROUND ART Conventionally, various types of holders for wiring and piping materials have been used for fixing to wall surfaces such as the structural surfaces of buildings and the column surfaces of construction materials, in order to support and route wiring and piping materials on the wall surfaces.
[0003] For example, Patent Document 1 discloses a wiring / piping material fastener for gripping and fixing wiring / piping material to a structure such as a wall. In the following paragraphs, the reference numerals of Patent Document 1 are indicated in parentheses. The wiring / piping material holder (100) includes a first holding piece (110), a second holding piece (120) connected to the first holding piece (110) so as to surround the wiring / piping material (P) and hold it along the installation direction, a hinge (130) rotatably connecting the base end of the first holding piece (110) to the base end of the second holding piece (120), and an auxiliary piece (140) extending from the inner surface of the first holding piece (110) with its tip as a free end. The second holding piece (120) overlaps with the first holding piece (110) from outside the holding space (101). The outer surface of the first retaining piece (110) and the inner surface of the second retaining piece (120) are provided with a first locking tooth row (113) and a second locking tooth row (123) that lock the first retaining piece (110) and the second retaining piece (120) together to maintain their overlap. The first locking tooth row (113) and the second locking tooth row (123) are configured to allow relative movement of the first retaining piece (110) and the second retaining piece (120) in a forward direction that increases the amount of overlap, and to restrict relative movement in a backward direction that decreases the amount of overlap. The auxiliary piece (140) is located between the wiring / piping material (P) placed in the retaining space (101) and the hinge (130), and has an abutment portion (142) that can abut against the outer peripheral surface of the wiring / piping material (P). This auxiliary piece (140) can support the wiring / piping material (P) by biasing it from the hinge side space (105) when the overlapping of the first holding piece (110) and the second holding piece (120) is promoted to reduce the holding space (101) in order to hold wiring / piping materials (P, PS, PL) of different diameters. In other words, the auxiliary piece (140) enables the wiring / piping material holder (100) to hold wiring / piping materials (P, PS, PL) of different diameters more stably.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-53585 Summary of the Invention [Problem to be solved by the invention]
[0005] The wiring and piping material holder of Patent Document 1 is provided with an auxiliary piece, which enables it to stably hold wiring and piping materials of different diameters. However, if the auxiliary piece falls to the tip end (the opposite side of the hinge) when placing the wiring and piping material into the holding space, it is necessary to place the wiring and piping material into the holding space while lifting it toward the base end, which reduces operability. In other words, a challenge for conventional wiring and piping material holders is how to stably hold two or more types of wiring and piping materials of different diameters while improving operability.
[0006] The present invention has been made to solve the above-mentioned problems, and its object is to provide a wiring and piping material holder that is easy to operate and can stably hold wiring and piping material. [Means for solving the problem]
[0007] (Configuration 1) A wiring / piping material holder according to one embodiment of the present invention is a wiring / piping material holder capable of holding two or more types of wiring / piping materials having different diameters, an inner overlapping piece extending from a base end to a tip end and having an inner locking portion on the tip end side; an outer overlapping piece extending from the base end to the tip end and having an outer engaging portion on the tip end side; a hinge that connects the base end of the inner overlapping piece and the base end of the outer overlapping piece so that they can rotate relatively, The tip end portion of the inner overlapping piece overlaps the tip end portion of the outer overlapping piece from the inside, and they cooperate to form an annular holding space inside for surrounding the wiring and piping material, the inner locking portion and the outer locking portion are configured to lock with each other in the circumferential direction so as to restrict relative movement in the circumferential direction in a direction that expands the holding space when the tip portions of the inner overlapping piece and the outer overlapping piece overlap each other, and are configured to be relatively movable in a direction that gradually reduces the holding space so that the inner surfaces of the inner overlapping piece and the outer overlapping piece can be pressed against the outer surfaces of the wiring / piping material placed in the holding space, a pair of contact portions are formed on the inner surface of the tip end side of the inner overlapping piece and the inner surface of the base end side of the outer overlapping piece, the contact portions being brought into preferential contact with the outer surface of the wiring / piping material held in pressure contact within the holding space; At least one of the pair of abutment portions is characterized by acting to convert the reaction force received when pressed against the outer surface of the wiring / piping material into a biasing force that biases the inner engaging portion and the outer engaging portion in a direction that brings them closer to each other in the inward and outward directions of the holding space.
[0008] (Configuration 2) A further aspect of the present invention provides a holder for wiring and piping material according to the first aspect, wherein a first arc-shaped portion having a first circular center point is formed on an inner surface of the tip end of the inner overlapping piece, a second arc-shaped portion having a second circular center point is formed on the inner surface of the base end side of the outer overlapping piece; The first arc-shaped portion and the second arc-shaped portion are configured such that, in a holding state in which the inner overlapping piece and the outer overlapping piece overlap to press and hold the wiring / piping material, the first circular center point is positioned more to the base end side than the second circular center point. [Effects of the Invention]
[0009] According to one embodiment (Configuration 1) of the wiring / piping material holder of the present invention, a pair of abutment portions is formed on the inner surface of the distal end of the inner overlapping piece and the inner surface of the proximal end of the outer overlapping piece, which preferentially abut against the outer surface of the wiring / piping material held in a pressure-contact state within the holding space. At least one of the pair of abutment portions converts the reaction force received when the wiring / piping material is pressed against the outer surface of the wiring / piping material into a biasing force that biases the inner locking portion and the outer locking portion toward each other in the inward / outward direction of the holding space, thereby improving the ability to maintain the inward / outward engagement. This allows the wiring / piping material holder to stably hold two or more types of wiring / piping material with different diameters. Furthermore, when the wiring / piping material holder presses and holds the wiring / piping material, the abutment portion on the inner surface of the distal end of the inner overlapping piece and the abutment portion on the inner surface of the proximal end of the outer overlapping piece preferentially abut against the outer surface of the wiring / piping material, thereby clamping and holding the wiring / piping material. In other words, the wiring and piping material holder of the present invention can more easily form a stable holding state by preferential pressure contact between a pair of abutting parts, without the need to provide an auxiliary piece as in conventional devices, or to reduce the holding space by applying a strong force until the inner surface of at least one of the overlapping pieces is bent and deformed to fit the outer surface of the wiring and piping material. Therefore, the wiring and piping material holder of the present invention can stably hold two or more types of wiring and piping material with good operability.
[0010] According to a wiring / piping material holder of a further embodiment (Configuration 2) of the present invention, in addition to the effects of the wiring / piping material holder of Configuration 1, when the inner and outer overlapping pieces overlap to press and hold the wiring / piping material, the first circular center point is positioned more proximally than the second circular center point. That is, the first circular arc-shaped portion serves as a contact portion on the inner surface of the distal end of the inner overlapping piece, and the second circular arc-shaped portion serves as a contact portion on the inner surface of the proximal end of the outer overlapping piece, and both of these portions preferentially press and hold the wiring / piping material. Furthermore, when the wiring / piping material is pressed and held, the inner and outer overlapping pieces attempt to form a common circle that conforms to the outer peripheral shape of the wiring / piping material, generating a force that tends to deform the inner and outer overlapping pieces in a direction that brings the first and second circular center points closer to each other. This force acts as a reaction force to bias the first circular arc-shaped portion of the inner overlapping piece toward the distal end and / or the second circular arc-shaped portion of the outer overlapping piece toward the proximal end. As a result, the reaction force received when the inner and outer locking portions are pressed against the outer surface of the wiring / piping material can be effectively converted into a biasing force that moves the inner and outer locking portions closer together in the inward and outward directions.

DETAILED DESCRIPTION OF THE INVENTION
[0012] An embodiment of the present invention will be described below with reference to the drawings. The shapes of the drawings referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily correspond to the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios shown in the drawings. Furthermore, the up, down, left, and right directions in the present invention are merely concepts indicating relative positions, and needless to say, these directions can be interchanged and applied.
[0013] A wiring / piping material holder 100 according to one embodiment of the present invention is fixed to a structure such as a building material or a wall material, and is used to install wiring / piping material within the structure. In this embodiment, the structure to which the wiring / piping material holder 100 is fixed is a building material 11 having an installation surface (or installation surface) on one side, and the wiring / piping material P is exemplified as a corrugated flexible pipe. The wiring / piping material P is formed so that peaks (large diameter portions) and valleys (small diameter portions) alternately and continuously in the longitudinal direction. However, this embodiment is merely one example of the present invention, and its use and configuration are not limited thereto as long as they do not deviate from the technical scope of the present invention. The configuration of the wiring / piping material holder 100 according to the present invention will be described below.
[0014] 1(a) and 1(b) are perspective views of a wiring / piping material holder 100 according to one embodiment of the present invention. FIG. 2 is a front view of the wiring / piping material holder 100. FIGS. 3(a) to 3(d) are a plan view, a left side view, a right side view, and a bottom view of the wiring / piping material holder 100. FIG. 4 is a cross-sectional view of the wiring / piping material holder 100.
[0015] The wiring / piping material holder 100 of this embodiment is configured to be fixed to a structure and to hold or grip wiring / piping material P in a holding space 101 serving as a holding portion, thereby arranging the wiring / piping material P in a predetermined arrangement direction along the wall surface of the structure. As shown in FIG. 2 , the wiring / piping material holder 100 has a substantially C-shape in front view, defining an open holding space 101 at the opening. In this embodiment, the wiring / piping material holder 100 is integrally molded from synthetic resin, and the band-shaped portion is flexible and elastic. Here, the holding space 101 refers to an area in which wiring / piping material P having a predetermined diameter as the object to be held is held, but it can also be interpreted as an area whose outer edge varies according to the diameter (corresponding minimum diameter to corresponding maximum diameter) of the wiring / piping material P to be held.
[0016] Furthermore, the wiring / piping material holder 100 is configured to be able to hold two or more types of wiring / piping material P having different diameters ranging from a minimum diameter to a maximum diameter in the holding space 101. Here, the corresponding maximum diameter of the wiring / piping material P is determined by the diameter of the longest body whose outer circumferential surface can be enclosed in the (closed) holding space 101. On the other hand, the corresponding minimum diameter of the wiring / piping material P is determined by the diameter of the smallest long body that can hold the wiring / piping material P without moving in the holding space 101. Furthermore, in the case of a corrugated flexible tube, the diameter of the wiring / piping material P referred to here is the outer diameter of the peak portion.
[0017] The wiring / piping material holder 100 of this embodiment includes a base 110 extending from its base end to its tip, a pivoting piece 120 extending from its base end to its tip and cooperating with the base 110 to surround the wiring / piping material P and hold it aligned in the installation direction, and a hinge 130 pivotally connecting the base end of the base 110 to the base end of the pivoting piece 120. In the wiring / piping material holder 100 of this embodiment, the base 110, the pivoting piece 120, and the hinge 130 are integrally formed. The base 110 is fixed to the installation surface and is an inner overlapping piece whose tip overlaps with the tip of the pivoting piece 120 from the inside. On the other hand, the pivoting piece 120 is pivotally connected to the base 110 and is an outer overlapping piece whose tip overlaps with the tip of the base 110 from the outside. Here, the direction in which the wiring / piping material holder 100 (base 110 and pivot piece 120) extends in a C-shape or annular shape (the direction surrounding the wiring / piping material P) is defined as the circumferential direction, and the direction inward and outward of the holding space 101 (the radial direction of the wiring / piping material P) is defined as the radial direction. The side of the wiring / piping material holder 100 where the hinge 130 is formed is defined as the base end side, and the side where the open portion is formed is defined as the tip end side. The left-right direction between the base end and the tip end along the fixing surface 111a (installation surface) as viewed from the front is defined as the base-tip direction (or X-axis direction). The direction perpendicular to the base-tip direction of the wiring / piping material holder 100 (base 110 and pivot piece 120) (the direction in which the wiring / piping material P is arranged) is defined as the width direction. Furthermore, the up-down direction as viewed from the front, which is perpendicular to the fixing surface 111a (installation surface) of the wiring / piping material holder 100, is defined as the erection direction (or Y-axis direction).
[0018] As shown in FIGS. 1 to 4 , in the initial state of the wiring / piping material holder 100 (not holding the wiring / piping material P), an expandable or closable opening is formed between the tip of the base 110 and the tip of the pivot piece 120 for introducing the wiring / piping material P therein. A holding space 101 for holding the wiring / piping material P is defined inside the base 110 and the pivot piece 120, communicating with the opening. Then, the base 110 and the pivot piece 120 rotate or displace relatively around the hinge 130, and the tip portion of the base 110 overlaps with the tip portion of the pivot piece 120, thereby forming an annular holding space 101 that circumferentially surrounds the wiring / piping material P. At this time, the pivot piece 120, which serves as the outer overlapping piece, overlaps with the base 110, which serves as the inner overlapping piece, from the outside (radially outside) of the holding space 101. This closed holding space 101 can be maintained by the engagement of the inner locking portion 115 of the base 110 and the outer locking portion 125 of the rotating piece 120. The inner locking portion 115 and the outer locking portion 125 can be released from the engagement by moving away from each other in a direction different from the engagement direction (i.e., in the radial direction).
[0019] Furthermore, the wiring / piping material holder 100 can gradually reduce the size of the holding space 101 by gradually increasing the overlap between the tip portions while maintaining the locked state between the inner locking portion 115 and the outer locking portion 125. That is, as the amount of overlap between the base 110 and the pivot piece 120 increases, the amount of locking between the inner locking portion 115 and the outer locking portion 125 increases, or the relative locking positions of the inner locking portion 115 and the outer locking portion 125 change.
[0020] Each component of the wiring / piping material holder 100 of this embodiment will be described in detail below.
[0021] The base 110 extends from the base end to the tip end and is composed of a block-shaped wall portion located from the base end to the center, and an arm-shaped wall portion erected at the tip end of the block-shaped wall portion. This arm-shaped wall portion forms the tip portion of the base 110 and is capable of bending and deforming inward and outward. A thin hinge 130 is connected to the base end of the block-shaped wall portion of the base 110. The base 110 comprises a base portion 111 as a foundation to be fixed to a structure, a base-side gripping portion 112 connected to the base portion 111 and forming an arc-shaped recess on its inner surface for gripping the wiring / piping material P, and an inner locking portion 115 for maintaining the surrounding of the wiring / piping material P by the holding space 101.
[0022] As shown in FIG. 2, the base 111 extends in the base-tip direction (X-axis direction) of the base 110 and has a base-side side portion on the right side (toward the hinge 130) in the base-tip direction as viewed from the front and a tip-side side portion on the left side (toward the open portion) as viewed from the front. Here, the base-side side portion and the tip-side side portion are both edges (excluding movable portions) of the base 110 as viewed from the front. A flat fixing surface 111a is defined on the bottom surface of the base 111. As shown in FIG. 4, a recess 111b for accommodating the head of a fixing screw is provided in approximately the center of the base 111 in the base-tip direction. A fixing portion 111c is formed at the bottom of the recess 111b, penetrating the base 111 from top to bottom and allowing the shank of a screw to be inserted therethrough when fixing the base 111 to a structure to fix the base 111 to an installation surface.
[0023] The base-side gripping portion 112 forms an arc-shaped recess above the base 111, extending from the base end to the tip of the base 110, so as to grip the wiring / piping material P. A portion of the base-side gripping portion 112 rises from the base 111 toward the tip of the base 110. The base-side gripping portion 112 is formed as a curved surface that is approximately arc-shaped in cross section on the inner surface of the recess facing the rotating piece 120. This curved surface is defined as a first arc-shaped portion. In particular, the base-side gripping portion 112 is formed on at least the inner surface on the tip side of the base 110 and includes a first arc-shaped portion that forms an arc with a first circular center point 113. In a front view, this first arc-shaped portion extends along an imaginary circle having a predetermined diameter and centered at the first circular center point 113. As will be described later, the first arc-shaped portion acts as a first abutment portion that preferentially abuts against the outer surface of the wiring / piping material P from the tip side when holding a wiring / piping material P with a compatible diameter. Preferably, the arc shape of the first arc-shaped portion is determined to approximately match the circumference of the wiring / piping material with the compatible maximum diameter. In other words, the curvature of the first arc-shaped portion corresponds to the circle of the compatible maximum diameter. In addition, an arc-shaped plate-like rib is provided on the inner surface of the base-side gripping portion 112 to fit into the valleys of the wiring / piping material P, which is a corrugated flexible tube, and engage the wiring / piping material P in the longitudinal direction.
[0024] The inner locking portion 115 is formed on the arc-shaped outer surface of the arm-shaped wall of the base 110 as a row of locking teeth formed consecutively in the direction of stacking. The inner locking portion 115 functions to relatively lock the pivot piece 120 (outer locking portion 125) from the inside in the inward / outward direction. The inner locking portion 115 also extends over most of the circumferential direction of the outer surface of the arm-shaped wall. Each locking tooth constituting the inner locking portion 115 has a sawtooth shape with an inclined surface at its tip and a locking surface on the opposite side that stands approximately perpendicular to the outer surface of the arm-shaped wall. The teeth allow movement in only one direction relative to the approximately sawtooth-shaped locking teeth of the outer locking portion 125 (described later) and act to lock in the other direction. The inner locking portion 115 has a greater number of locking teeth than the outer locking portion 125. The greater the number of locking teeth that make up the inner locking portion 115, the more it is possible to maintain the connection between the base 110 and the pivot piece 120 while reducing the holding space 101. In other words, the maximum overlapping amount between the base 110 and the pivot piece 120 is determined by the number of locking teeth of either the inner locking portion 115 or the outer locking portion 125, whichever has the greater number of locking teeth. It is also preferable that the locking teeth of the inner locking portion 115 have the same shape.
[0025] The pivoting piece 120 is a strip extending in an arch shape from the base end to the tip end. The pivoting piece 120 has a base end portion curved in an arc shape and a tip end portion connected to the base end portion and curved more gently via a bent portion. A thin hinge 130 is connected to the base end portion of the pivoting piece 120. The curved shape of the tip end portion of the pivoting piece 120 corresponds to the curved shape of the outer surface of the arm-shaped wall portion of the base 110 so that it overlaps the tip end portion of the base 110.
[0026] The rotating piece 120 includes a rotating piece gripping portion 122 that forms an arc-shaped recess on its inner surface for gripping the wiring / piping material P, and an outer locking portion 125 that maintains the surrounding of the wiring / piping material P by the holding space 101. A deformation starting point 126 is formed at the bent portion of the rotating piece 120, which serves as a starting point (rotation center) when the tip portion of the rotating piece 120 rotates radially outward. The tip portion of the rotating piece 120 can be flexibly deformed inward and outward around the deformation starting point 126, which allows the outer locking portion 125 to easily move relatively in a direction away from the inner locking portion 115.
[0027] The rotating piece gripping portion 122 forms an arc-shaped recess along the base-to-tip direction of the rotating piece 120 so as to grip the wiring / piping material P. The rotating piece gripping portion 122 is formed in the base-end region of the rotating piece 120 and is formed as a curved surface that is approximately arc-shaped in cross section on the inner surface of the recess facing the base 110. This curved surface is defined as a second arc-shaped portion. In particular, the rotating piece gripping portion 122 is formed on at least the inner surface of the rotating piece 120 on the base-end side (closer to the base end) and includes a second arc-shaped portion that forms an arc having a second circular center point 123. In the front view shown in FIG. 2 , this second arc-shaped portion extends along an imaginary circle having a predetermined diameter and centered at the second circular center point 123. When the opening is open as shown in FIG. 2, the second circular center point 123 is positioned closer to the base end than the first circular center point 113. However, when the inner locking portion 115 and the outer locking portion 125 are locked, the positional relationship is reversed, with the first circular center point 113 positioned closer to the base end than the second circular center point 123 in the base-to-tip direction (X-axis direction) (see FIGS. 6 and 7). As described below, the second arc-shaped portion acts as a second abutment portion that preferentially abuts against the outer surface of the wiring / piping material P from the base end side when holding a wiring / piping material P with a compatible diameter. Preferably, the arc shape of the second arc-shaped portion has the same radius of curvature as the first arc-shaped portion and is determined to approximately coincide with the circumference of the wiring / piping material with the largest compatible diameter. In other words, the curvature of the second arc-shaped portion corresponds to the circle of the largest compatible diameter. The inner surface of the rotating half gripping portion 122 is provided with an arc-shaped plate-like rib that fits into the valley of the wiring / piping material P, which is a corrugated flexible tube, and locks the wiring / piping material P in the longitudinal direction.
[0028] An outer locking portion 125 is formed on the inner surface of the tip portion of the rotating piece 120 as a locking tooth row consisting of multiple locking teeth formed continuously in the direction of polymerization. The outer locking portion 125 functions as an outer locking portion that relatively locks the base 110 (inner locking portion 115) from the outside in the inward / outward direction. The outer locking portion 125 is made up of multiple locking teeth (three in this embodiment) formed on the tip side of the rotating piece 120. Each locking tooth that makes up the outer locking portion 125 has an inclined surface on the tip side and an locking surface on the opposite side that stands approximately vertically from the inner surface of the rotating piece 120, forming a roughly sawtooth shape.
[0029] When the distal ends of the base 110 and the pivot piece 120 overlap, the locking teeth of the inner locking portion 115 and the outer locking portion 125 engage with each other in the radial direction with a click. At this time, the inclined surfaces of the locking teeth slide against each other, allowing relative movement in a direction that gradually advances the overlap and reduces the holding space 101. In other words, as the amount of overlap increases, the engaging teeth are swapped. As the overlap advances, when one locking tooth overcomes the opposing locking tooth by sliding their inclined surfaces against each other and then engages with the next locking tooth, the user can feel a click and hear the engagement of the locking teeth. Meanwhile, the locking surfaces of the locking teeth engage with each other, restricting relative movement in a direction that retracts the overlap and expands the holding space 101. Furthermore, the outer locking portion 125 displaces radially outward relative to the inner locking portion 115, releasing the engagement between the two locking teeth. On the other hand, the inner and outer locking portions 115 and 125 are biased in directions in which they approach each other inward and outward, thereby stably maintaining the locked state.
[0030] The hinge 130 connects the base end of the base 110 and the pivoting piece 120 and is configured to pivot the pivoting piece 120 in the opening and closing directions relative to the base 110. The hinge 130 is a thin piece that is relatively thin compared to the base 110 and the pivoting piece 120, and is elastically deformable preferentially over other parts. When the base 110 and the pivoting piece 120 are displaced in a direction in which they overlap, the hinge 130 is bent and deformed at an acute angle. On the other hand, when the base 110 and the pivoting piece 120 are displaced in a direction in which the opening portion is enlarged, the hinge 130 is bent and deformed at an obtuse angle. Due to the bending of the hinge 130, a hinge-side space is formed inside it.
[0031] In the wiring / piping material holder 100 of this embodiment, a pair of abutment portions is formed on the inner surface of the tip end side of the base 110 as the inner overlapping piece and the inner surface of the base end side of the rotating piece 120 as the outer overlapping piece, which can preferentially abut against the outer surfaces of at least two types of wiring / piping material P held in pressure contact within the holding space 101. In other words, a portion of the inner surface of the base side gripping portion 112 abuts against the outer surface of the wiring / piping material P from the tip end side (the distal side of the hinge 130 on the periphery of the holding space 101) as a first abutment portion, and a portion of the inner surface of the rotating piece side gripping portion 122 abuts against the outer surface of the wiring / piping material P from the base end side (the proximal side of the hinge 130 on the periphery of the holding space 101) as a second abutment portion, thereby allowing the wiring / piping material P to be clamped from both the tip end side and the base end side by the pair of abutment portions (or clamping portions). In particular, the first arc-shaped portion of the base-side gripping portion 112 and the second arc-shaped portion of the rotating piece-side gripping portion 122 are configured so that, in a holding state (locked state) in which the base 110 and the rotating piece 120 are overlapped, the first circular center point 113 is positioned more to the base end side (in the base-to-tip direction) than the second circular center point 123 (see FIGS. 6 and 7). This positional relationship makes it possible for the converting abutment to act to convert the reaction force received when pressed against the outer surface of the wiring / piping material P into an urging force for pressing the inner locking portion 115 and the outer locking portion 125 against each other in the inward / outward direction.
[0032] Next, an installation structure 10 will be described in which wiring and piping material P is held and arranged on a construction material 11 (structure) using the wiring and piping material holder 100 of this embodiment. FIG. 5 is a schematic perspective view of the installation structure 10 using the wiring and piping material holder 100 of this embodiment. In the installation structure 10 of this embodiment, the structure is a columnar construction material 11 that stands upright, and the wiring and piping material holder 100 is fixed to the front side (installation surface) of the construction material 11. The wiring and piping material P is gripped by the wiring and piping material holder 100 and arranged so that its arrangement direction is aligned with the vertical direction of the construction material 11. In this installation structure 10, the fixing surface 111a of the base 111 of the wiring and piping material holder 100 abuts against the side surface of the construction material 11, and a screw penetrates the fixing portion 111c, thereby fixing the wiring and piping material holder 100 to the construction material 11. At this time, the head of the screw is received in the recess 111b of the base 111, and the shank is screwed into the construction material 11. As a result, the wiring / piping material holder 100 is fixed in a position in which its width direction is aligned with the vertical direction of the construction material 11.
[0033] The wiring / piping material holder 100 of this embodiment is capable of crimping and holding two or more types of wiring / piping material P having different diameters ranging from a corresponding minimum diameter to a corresponding maximum diameter. The corresponding minimum diameter corresponds to the size of the periphery of the holding space 101 when the base-most locking tooth of the inner locking portion 115 engages with the base-most locking tooth of the outer locking portion 125. The corresponding maximum diameter corresponds to the size of the periphery of the holding space 101 when the tip-most locking tooth of the inner locking portion 115 engages with the tip-most locking tooth of the outer locking portion 125. Here, the first diameter is larger than the corresponding minimum diameter, the second diameter is smaller than the corresponding maximum diameter, and the first diameter is smaller than the second diameter.
[0034] 6 and 7, an exemplary configuration in which two types of wiring and piping materials P1, P2 having different diameters are held by the wiring and piping material holder 100 will be described. Fig. 6 shows a configuration in which a first wiring and piping material P1 having a first diameter (relatively small diameter) among two or more types of wiring and piping materials having different diameters is held by the wiring and piping material holder 100. Fig. 7 shows a configuration in which a second wiring and piping material P2 having a second diameter (relatively large diameter) among two or more types of wiring and piping materials having different diameters is held by the wiring and piping material holder 100.
[0035] 6, the wiring / piping material P1 is placed in the holding space 101, the tip portion of the base 110 and the tip portion of the rotating piece 120 overlap, the inner locking portion 115 and the outer locking portion 125 engage, and the base-side gripping portion 112 and the rotating piece-side gripping portion 122 press against the outer surface of the wiring / piping material P1, thereby holding the wiring / piping material P1 in pressure contact with the wiring / piping material holder 100. The outer locking portion 125 is locked at a position close to the lower end of the inner locking portion 115. Here, the first circular center point 113 of the first circular arc-shaped portion of the base 110 is positioned more to the base end side than the second circular center point 123 of the second circular arc-shaped portion of the rotating piece 120 in the base-to-tip direction. A portion of the inner surface of the base-side gripping portion 112, which forms the first arc-shaped portion, serves as a first abutment portion and is preferentially abutted against the outer surface of the wiring / piping material P1 from below (the installation surface side) and from the tip side. At this time, the abutment portion on the first arc-shaped portion is pressed against the outer surface of the wiring / piping material P1, and a gap is formed between the first arc-shaped portion and the outer surface of the wiring / piping material P1 in areas other than the abutment portion. On the other hand, a portion of the inner surface of the rotating half-side gripping portion 122, which forms the second arc-shaped portion, serves as a second abutment portion and is preferentially abutted against the outer surface of the wiring / piping material P1 from above (the opposite side of the installation surface) and from the base end side. At this time, the abutment portion on the second arc-shaped portion is pressed against the outer surface of the wiring / piping material P1, and a gap is formed between the second arc-shaped portion and the outer surface of the wiring / piping material P1 in areas other than the abutment portion. In this way, the pair of abutting portions clamp the wiring / piping material P1 from both sides in the diagonal direction, so that the wiring / piping material P1 is firmly held within the holding space 101 so as not to move.
[0036] The pair of contact portions clamp the wiring / piping material P1 from the distal end and proximal end, thereby applying a pressure force in the proximal-tip direction to the outer surface of the wiring / piping material P1. This pressure force can act as a reaction force that urges the base 110 and the pivot piece 120 in the opposite direction to the pressure force. As shown in FIG. 6, the pressure force and the reaction force have diagonal vectors, but with regard to the action of the reaction force, the vector component in the proximal-tip direction (X-axis direction) is particularly important. In FIG. 6 (and FIG. 7), the diagonal reaction force received from the wiring / piping material P1 is represented by f, and its X-component is schematically represented by fx. This proximal-tip direction reaction force fx (X-axis component) urges the base 110 toward the distal end in the proximal-tip direction via the first contact portion, and urges the pivot piece 120 toward the proximal end in the proximal-tip direction via the second contact portion. The arrows f and fx in the figure are intended to explain the reaction forces of the present invention, and as a result, it is sufficient that the inner locking portion 115 and the outer locking portion 125 can be biased in a direction toward each other along the inward and outward directions of the retaining space 101, and are not limited to the depiction in the figure.
[0037] 6, the reaction force urges the block-shaped wall portion of the base 111 toward the tip end, and also urges the flexible base-end portion of the rotating piece 120 toward the base end. In particular, the urging of the flexible base-end portion of the rotating piece 120 toward the base end urges the outer locking portion 125 of the rotating piece 120 in the outward and inward directions, and as a result, the inner locking portion 115 and the outer locking portion 125 are urged in directions that bring them relatively closer to each other along the radial direction. In other words, of the two obliquely opposing abutment portions (sandwiching portions), at least one (particularly the abutment portion on the rotating piece 120 side) acts as a converting abutment portion (or a preferential abutment portion). Therefore, the reaction force received when the pair of abutment portions are pressed against the outer surface of the wiring / piping material P is converted into a biasing force that biases the inner locking portion 115 and the outer locking portion 125 in a direction that brings them closer to each other in the inward / outward direction, so that the inner locking portion 115 and the outer locking portion 125 are pressed against each other in the opposing direction with greater force, and the locked state of the inner locking portion 115 and the outer locking portion 125 is maintained stably.
[0038] As shown in FIG. 7 , a wiring / piping material P2 having a second diameter larger than the first diameter is placed in the holding space 101, the tip portion of the base 110 and the tip portion of the rotating piece 120 overlap, the inner locking portion 115 and the outer locking portion 125 engage, and the base-side gripping portion 112 and the rotating piece-side gripping portion 122 press against the outer surface of the wiring / piping material P2, thereby holding the wiring / piping material P2 in pressure contact with the wiring / piping material holder 100. The outer locking portion 125 locks at a position close to the tip of the inner locking portion 115. Here, as in the embodiment of FIG. 6 , the first circular center point 113 of the first circular arc-shaped portion of the base 110 is positioned more proximal to the base end than the second circular center point 123 of the second circular arc-shaped portion of the rotating piece 120 in the base-to-tip direction. A portion of the inner surface of the base-side gripping portion 112, which forms the first arc-shaped portion, serves as a first abutment portion and is preferentially abutted against the outer surface of the wiring / piping material P2 from below (the installation surface side) and from the tip side. At this time, the abutment portion on the first arc-shaped portion is pressed against the outer surface of the wiring / piping material P2, and a gap is formed between the first arc-shaped portion and the outer surface of the wiring / piping material P2 in areas other than the abutment portion. On the other hand, a portion of the inner surface of the rotating half-side gripping portion 122, which forms the second arc-shaped portion, serves as a abutment portion and is preferentially abutted against the outer surface of the wiring / piping material P2 from above (the opposite side of the installation surface) and from the base end side. At this time, the abutment portion on the second arc-shaped portion is pressed against the outer surface of the wiring / piping material P2, and a gap is formed between the second arc-shaped portion and the outer surface of the wiring / piping material P2 in areas other than the abutment portion. In this way, the pair of abutting portions clamp the wiring / piping material P2 from both sides in the diagonal direction, thereby firmly holding the wiring / piping material P2 so that it does not move within the holding space 101. Furthermore, since the wiring / piping material P2 has a larger diameter than the form in Fig. 6, the area that comes into pressure contact with the outer surface of the wiring / piping material P2 is larger, and the gap is smaller.
[0039] 7, the reaction force urges the flexible arm-shaped wall portion of the base 111 toward the tip end, and urges the flexible base end portion of the rotating piece 120 toward the base end. In particular, the tip end portion of the base 110 is urged toward the tip end (inward / outward direction), and the base end portion of the rotating piece 120 is urged toward the base end (outward / inward direction), so that the inner locking portion 115 and the outer locking portion 125 are urged in directions that bring them closer to each other in the radial direction. In other words, of the two obliquely opposing abutment portions (sandwiching portions), at least one (both the abutment portion on the base 110 side and the abutment portion on the rotating piece 120 side) acts as a conversion abutment portion (or a priority abutment portion). Therefore, the reaction force received when the pair of abutment portions are pressed against the outer surface of the wiring / piping material P is converted into a biasing force that biases the inner locking portion 115 and the outer locking portion 125 in a direction that brings them closer to each other in the inward / outward direction, so that the inner locking portion 115 and the outer locking portion 125 are pressed against each other in the opposing direction with greater force, and the locked state of the inner locking portion 115 and the outer locking portion 125 is maintained stably.
[0040] 6 and 7, the first circular center point 113 of the first circular arc-shaped portion of the base 110 is positioned closer to the base end than the second circular center point 123 of the second circular arc-shaped portion of the pivot piece 120. However, in the configuration of FIG. 7, the first circular center point 113 and the second circular center point 123 are closer together. However, the wiring and piping material holder 100 of this embodiment is configured to maintain the positional relationship between the first circular center point 113 and the second circular center point 123 as long as it holds at least two types of wiring and piping materials P1, P2 having diameters between the minimum and maximum corresponding diameters. That is, in each state in which wiring and piping materials P1, P2 of different diameters are pressure-welded and held, a common circle corresponding to each wiring and piping material P1, P2 is formed, and a force is generated that tries to deform the base 110 and the pivot piece 120 in a direction that brings the first circular center point 113 and the second circular center point 123 closer to each other. This force acts as a reaction force to urge the base 110 toward the tip end and / or to urge the pivot piece 120 toward the base end. As a result, the reaction force received when the inner and outer locking portions 115 and 125 are pressed against the outer surfaces of the wiring and piping materials P1 and P2 can be effectively converted into a urging force that urges the inner and outer locking portions 115 and 125 in directions that bring them closer to each other in the inward and outward directions.
[0041] Next, a method for constructing an installation structure 10 using the wiring / piping material holder 100 of this embodiment will be described. First, the base 111 of the wiring / piping material holder 100 is fixed to a predetermined position on the side of the construction material 11 with screws. Then, as shown in FIG. 8 , the pivoting piece 120 of the wiring / piping material holder 100 is pivoted relative to the base 110 via the hinge 130, thereby moving the tip of the pivoting piece 120 away from the tip of the base 110 and widening the opening. The wiring / piping material P is introduced into the holding space 101 through this widened opening. Next, the tip of the pivoting piece 120 is brought into contact with the tip of the base 110, thereby closing the opening and forming a locked state in which the inner locking portion 115 and the outer locking portion 125 are locked to each other. The base 110 and the pivoting piece 120 are then moved relative to each other in a direction gradually reducing the holding space 101 until the base-side gripping portion 112 and the pivoting piece-side gripping portion 122 are pressed against the outer surface of the wiring / piping material P. At this time, the abutting portion on the inner surface of the tip end of the base 110 and the abutting portion on the inner surface of the base end of the pivoting piece 120 are brought into preferential contact with the outer surface of the wiring / piping material P, thereby clamping and holding the wiring / piping material P. This makes it possible to more easily form a stable holding state through preferential pressure contact between the pair of abutting portions, without the need to provide an auxiliary piece as in the conventional method, or to reduce the holding space 101 with a strong force until the inner surface of at least one of the holding pieces (overlapping pieces) is bent and deformed to conform to the outer surface of the wiring / piping material. In this way, the wiring / piping material P is pressed and held by the wiring / piping material holder 100 fixed to the installation surface, making it possible to easily construct the installation structure 10.
[0042] The following describes the effects of the wiring / piping material holder 100 according to one embodiment of the present invention.
[0043] According to the wiring / piping material holder 100 of one embodiment of the present invention, a pair of abutment portions is formed on the inner surface of the tip end of the base 110 and the inner surface of the base end of the pivot piece 120, which preferentially abut against the outer surface of the wiring / piping material P (P1, P2) held in pressure contact within the holding space 101. The pair of abutment portions converts the reaction force received when pressed against the outer surface of the wiring / piping material P (P1, P2) into a biasing force that biases the inner locking portion 115 and the outer locking portion 125 in a direction that brings them closer together in the inward and outward directions, thereby improving the ability to maintain the inward and outward engagement. This allows the wiring / piping material holder 100 to stably hold two or more types of wiring / piping material P (P1, P2) having different diameters. Furthermore, when the wiring / piping material holder 100 presses and holds the wiring / piping material P, the first abutting portion on the inner surface of the distal end of the base 110 and the second abutting portion on the inner surface of the proximal end of the pivot piece 120 are preferentially abutted against the outer surface of the wiring / piping material P (P1, P2), thereby clamping and holding the wiring / piping material P (P1, P2). In other words, the wiring / piping material holder 100 of this embodiment can more easily form a stable holding state by preferentially pressing the pair of abutting portions together, without requiring the provision of an auxiliary piece as in conventional devices, or the need to reduce the holding space 101 with a strong force until the inner surface of at least one of the overlapping pieces is bent and deformed to conform to the outer surface of the wiring / piping material P (P1, P2). Therefore, the wiring / piping material holder 100 of this embodiment can stably hold two or more types of wiring / piping material P (P1, P2) with good operability.
[0044] The present invention is not limited to the above-described embodiment, and various modifications are possible. Modifications of the present invention will be described below.
[0045] (1) The wiring and piping material holder of the present invention is not limited to the configuration of the above-described embodiment. In the above-described embodiment, a base having a base portion fixed to an installation surface by a fixing portion is formed as the inner overlapping piece, and a pivoting piece pivotally connected to the base is formed as the outer overlapping piece. However, the present invention is not limited to this. That is, the base may be formed as the outer overlapping piece, and the pivoting piece may be formed as the inner overlapping piece. In this case, an outer locking portion is provided on the inner surface of the recess at the tip portion of the base, and an inner locking portion is provided on the outer surface of the tip portion of the pivoting piece. The tip portion of the base overlaps the tip portion of the pivoting piece from the inside of the holding space, thereby cooperating with each other to form an annular holding space inside for surrounding the wiring and piping material. Furthermore, a second arc-shaped portion having a second center point is formed on the inner surface of the distal end of the base (outer overlapping piece), and a first arc-shaped portion having a first center point is formed on the inner surface of the proximal end of the pivoting piece (inner overlapping piece). When the base (outer overlapping piece) and the pivoting piece (inner overlapping piece) are overlapped and held, the first center point is positioned closer to the proximal end than the second center point. The proximal inner surface of the base (outer overlapping piece) and the distal inner surface of the pivoting piece (inner overlapping piece) are formed with a pair of contact portions that preferentially contact the outer surface of the wiring / piping material held in the holding space. The pair of contact portions converts the reaction force received when the inner and outer locking portions are pressed against the outer surface of the wiring / piping material into a biasing force that biases the inner and outer locking portions toward each other in the inward and outward directions. That is, the wiring / piping material holder of the present invention may be configured in such a way that the inner and outer overlapping pieces are reversed in the above-described embodiment.
[0046] (2) The wiring / piping material holder of the present invention is not limited to the configuration of the above-described embodiment. In the above-described embodiment, the first circular center point of the first circular arc-shaped portion on the distal inner surface of the inner overlapping piece is located proximal to the second circular center point of the second circular arc-shaped portion on the proximal inner surface of the outer overlapping piece, thereby forming abutment portions on the distal inner surface of the inner overlapping piece and the proximal inner surface of the outer overlapping piece, respectively. However, the present invention is not limited to this. For example, protrusions protruding into the holding space may be provided on the distal inner surface of the inner overlapping piece and the proximal inner surface of the outer overlapping piece, and these protrusions may serve as abutment portions that preferentially abut the outer surface of the wiring / piping material. Even in this case, the pair of protrusions (abutment portions) may act to convert the reaction force received when the holder is pressed against the outer surface of the wiring / piping material into a biasing force that biases the inner and outer locking portions in a direction that brings them closer together in the inward / outward direction.
[0047] (3) The wiring and piping material holder of the present invention is not limited to the configuration of the above-described embodiment. In the wiring and piping material holder of the above-described embodiment, the base (inner overlapping piece), the pivoting piece (outer overlapping piece), and the hinge are integrally formed, but they may be a combination of separate pieces. The rigid base and the pivoting piece may be connected by a shaft-shaped hinge, and the base and the pivoting piece may pivot around the hinge.
[0048] (4) The wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring / piping material holder of the above embodiment, a locking tooth row with many locking teeth is formed as an inner locking portion on the side of the base (inner overlapping piece) that is fixed to a structure, and a locking tooth row with a few locking teeth is formed as an outer locking portion on the side of the rotating piece (outer overlapping piece). However, the relationship between the inner locking portion and the outer locking portion may be reversed, or a locking tooth row with many locking teeth may be formed on the inner surface of the rotating piece, and a locking tooth row with a few locking teeth may be formed on the outer surface of the base. Furthermore, the number of locking teeth on the inner locking portion and the number of locking teeth on the outer locking portion may be increased or decreased as desired within the technical scope of the present invention. Furthermore, the inner locking portion and the outer locking portion may each be configured to have multiple rows of locking teeth in the width direction.
[0049] (5) The wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring / piping material holder of the above embodiment, the multiple locking teeth of the inner locking portion and the outer locking portion are formed with the same shape, but the inner locking portion and the outer locking portion may be formed with different shapes as long as they can be locked to each other.
[0050] The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various forms within the technical scope of the present invention. That is, within the technical scope of the present invention, some of the configurations of the present embodiments may be omitted or modified, or other configurations may be added.
