[0004] [Patent Document 1] JP 2002-354637 A Summary of the Invention [Problem to be solved by the invention]

[0005] The fastener of Patent Document 1 has a through hole in the holding piece, which allows the fastening screw (screw) to be rotated while inserting a screwdriver (tool) into the through hole, simplifying the fastening operation. However, in the fastening operation of fixing the fastener to a structure, the user needs to rotate the fastening screw with a tool while separately holding the fastener, the fastening screw, and the screwdriver. In particular, it is difficult for the user to align the tip of the screwdriver with the drive part of the head of the fastening screw while holding both the fastener and the fastening screw in their hands. Therefore, the task is to improve the fastening operation to the structure using a tool and a screw.

[0006] The present invention has been made to solve the above-mentioned problems, and its object is to provide a fastener that makes it easier to fasten a structure using screws and tools. [Means for solving the problem]

[0007] The fastener according to claim 1 is a fastener that is fixed to a structure by a screwing operation of a screw into a screw-receiving portion of the structure using a tool, a base having an insertion portion through which a shaft portion of the screw is inserted and fixed to the structure via the screw and the insertion portion; The screw is disposed on the front side of the insertion portion in the screwing direction of the screw, The tool and The fixture and and a tool attachment portion configured to attach to the tool so as to prevent relative movement of the tool and to allow a screwing operation of the tool into the screw inserted into the insertion portion while maintaining a temporary holding state due to the attachment. 、 The tool attachment portion is formed in a through-hole having a size smaller than the head portion of the screw and capable of being clamped or pressed against a shank portion of the tool, Between the insertion portion and the tool attachment portion, a space is formed that allows the screw to be arranged in an upright position with the tip of the shank of the screw inserted into the insertion portion. It is characterized by:

[0008] The fastener of claim 2 is characterized in that, in the fastener of claim 1, the insertion portion is capable of temporarily fixing the screw, and the tool can be attached to the tool attachment portion to temporarily fix the screw to the insertion portion, and the tip of the tool can be maintained engaged with the head of the screw.

[0009] The fastener according to claim 3 is the fastener according to claim 1 or 2, wherein the tool attachment portion is formed on an inner surface of a through-hole through which the tool is disposed, and allows the tool to be inserted into the through-hole in the screwing direction, and the tool attachment portion is attached to an outer surface of the tool inserted into the through-hole. Inside The surfaces are configured to be in pressure contact with each other.

[0010] The fastener according to a fourth aspect of the present invention is the fastener according to the third aspect, wherein the through portion is an elongated hole extending in a direction intersecting the screwing direction.

[0011] The fixing device of claim 5 is characterized in that, in the fixing device of claim 4, one longitudinal end of the long hole is an open end, the tool attachment portion is formed by an inner surface facing the width direction of the long hole, and a restricting wall portion is formed on one end side of the long hole protruding from the inner surface of the long hole and restricting the tool from sliding within the long hole from the tool attachment portion toward the open end.

[0012] The fixing device described in claim 6 is characterized in that, in the fixing device described in any one of claims 1 to 5, the tool attachment portion allows relative rotation between the tool and the base when in a temporarily held state attached to the tool.

[0013] The fixing device according to claim 7 is the fixing device according to any one of claims 1 to 6, A first holding piece extending from a base end to a tip end and having the base portion on which the insertion portion is formed; a second holding piece extending from a base end to a tip end and movably connected to the base end of the first holding piece so as to cooperate with the first holding piece to surround and hold the wiring / piping material; A tip end side of the first holding piece and a tip end side of the second holding piece are engaged with each other to form an annular holding space surrounding the wiring / piping material, The tool attachment portion is formed on the second holding piece. Effect of the Invention

[0014] According to the fastener of claim 1, the tool attachment portion is disposed forward of the insertion portion in the screw-in direction, and is attached to the tool so as to prevent relative movement of the fastener. The tool attachment portion is configured so that the tool can be operated to screw in the screw inserted into the insertion portion while maintaining a state in which the tool attachment portion is temporarily held by the tool. This allows the user to rotate the tool in a temporarily held state in which the tool and fastener are integrally attached, and to screw the screw into the structure. Therefore, the fastener of the present invention makes it easier to fasten a structure using a screw and a tool.

[0015] According to the fastener described in claim 2, in addition to the effect of the invention of claim 1, by attaching a tool to the tool attachment part, temporarily fixing the screw to the insertion part, and maintaining the tip of the tool engaged with the head of the screw, it is possible to mesh the drive part of the screw with the tip of the tool at hand, and then place the fastener in a fixed position on the structure. This makes it easier to fix the fastener.

[0016] According to the fixture of claim 3, in addition to the effects of the invention of claim 1 or 2, the tool attachment part attaches to the tool by utilizing the pressure contact force between the inner surface of the through part and the outer surface of the tool. Thus, it is possible to form a temporary holding state with the tool at the same time as inserting the tool into the through part.

[0017] According to the fastener described in claim 4, in addition to the effect of the invention of claim 3, since the through portion is an elongated hole extending in a direction intersecting the screwing direction, it is possible to tilt the tool and screw relative to the insertion portion by moving the tool within the elongated hole.

[0018] According to the fixture of claim 5, in addition to the effect of the invention of claim 4, one end of the long hole in the longitudinal direction is an open end, so that the peripheral portion of the long hole can be flexibly deformed so as to expand the width of the long hole (the distance between the opposing inner surfaces). This makes it possible for tools of different thicknesses to be attached to the tool attachment portion by pressure contact with the opposing inner surfaces of the through-hole. Also, a restricting wall portion is formed on one end side of the tool attachment portion in the long hole, so that the tool attached to the tool attachment portion is engaged with the restricting wall portion and prevented from slipping out of the open end on one end side of the long hole.

[0019] According to the fastener described in claim 6, in addition to the effects of any one of the inventions of claims 1 to 5, the tool attachment portion is attached to the tool in a manner that allows relative rotation between the tool and the base, making it possible to perform screwing work while maintaining the posture of the fastener at the time of completion of fastening.

[0020] According to the fixture described in claim 7, in addition to the effects of any one of claims 1 to 6, by being fixed to a structure as a wiring / piping material holder, it becomes possible to hold and arrange wiring / piping material. In particular, in a temporary holding state in which a tool is attached to the tool attachment portion provided on the second holding piece, the tool can be screwed into the screw, so that the base of the first holding piece can be easily fixed to the structure. Then, after the fixture is fixed to the structure, the tool can be removed from the tool attachment portion, and the first holding piece and the second holding piece can hold and arrange the wiring / piping material.

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the shapes of the figures referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily match the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios in the drawings. Furthermore, the up, down, left, and right directions in the present invention are merely concepts indicating relative positions, and it goes without saying that they can be applied by being interchanged.

[0023] The fixture of one embodiment of the present invention is embodied as a wiring / piping material holder 100. The wiring / piping material holder 100 is fixed to a structure such as a building material, a wall material, or a pedestal, and is used for arranging wiring / piping materials in 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 an arrangement surface) on one side, and the wiring / piping material P is exemplified as a corrugated flexible tube. The wiring / piping material P is formed so that peaks (large diameter portions) and valleys (small diameter portions) are alternately and continuously arranged in the longitudinal direction. However, this embodiment is merely one example of the present invention, and it goes without saying that the use and configuration are not limited as long as they do not deviate from the technical scope of the present invention. Hereinafter, the configuration of the wiring / piping material holder 100 as a fixture of the present invention will be described.

[0024] Fig. 1(a) and (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. Fig. 3(a) to (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 to Fig. 6 are cross-sectional views of each portion of the wiring / piping material holder 100.

[0025] The wiring / piping material holder 100 of this embodiment is configured to be fixed to a structure and to hold or grip the wiring / piping material P in a holding space 101 as a holding part, thereby disposing the wiring / piping material P in a predetermined disposing direction along the wall surface of the structure. As shown in FIG. 2, the wiring / piping material holder 100 is substantially C-shaped in front view so as to define the holding space 101 opened at an open part 103. In this embodiment, the wiring / piping material holder 100 is integrally molded from synthetic resin, and has flexibility and elasticity in the belt-shaped part. Here, the holding space 101 means an area in which the 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 changes according to the diameter (corresponding minimum diameter to opposing maximum diameter) of the wiring / piping material P to be held.

[0026] The wiring / piping material holder 100 is configured to be capable of holding two or more types of wiring / piping materials having different diameters ranging from the minimum diameter to the maximum diameter in the holding space 101. Here, the wiring / piping material with the maximum corresponding diameter among the corresponding wiring / piping materials P is represented by PL, the wiring / piping material with the maximum corresponding diameter is represented by PS, and the wiring / piping material with no specified diameter is represented by P. The maximum corresponding diameter of the wiring / piping material is determined by the diameter of the maximum long body whose outer circumferential surface can be enclosed in the (closed) holding space 101. On the other hand, the minimum corresponding diameter of the wiring / piping material is determined by the diameter of the minimum long body that can hold the wiring / piping material in a state where the wiring / piping material is not moving in the holding space 101. It goes without saying that the wiring / piping material holder 100 may hold wiring / piping materials with a diameter smaller than the minimum corresponding diameter if it is not necessary to hold the wiring / piping material in a state where the wiring / piping material is not moving. The diameter of the wiring / piping material referred to here is the outer diameter of the crest in the case of a corrugated flexible tube.

[0027] The wiring / piping material holder 100 of this embodiment includes a first holding piece 110 extending from a base end to a tip end, a second holding piece 120 extending from the base end to the tip end and surrounding the wiring / piping material P in cooperation with the first holding piece 110 to hold it along the installation direction, a hinge 130 rotatably connecting the base end side of the first holding piece 110 and the base end side of the second holding piece 120 to each other, and an auxiliary piece 140 standing up from the inner surface of the first holding piece 110 with its tip end as a free end. In the wiring / piping material holder 100 of this embodiment, the first holding piece 110, the second holding piece 120, the hinge 130 and the auxiliary piece 140 are integrally formed. Here, the direction in which the wiring / piping material holder 100 (first holding piece 110 and second holding piece 120) extends in a C-shape or annular shape (the direction surrounding the wiring / piping material P) is defined as the extension direction or 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. Also, the direction perpendicular to the extension direction of the wiring / piping material holder 100 (first holding piece 110 and second holding piece 120) (the arrangement direction of the wiring / piping material P) is defined as the width direction. Furthermore, the up-down direction as viewed from the front, which is perpendicular to the bottom surface (fixing surface 111c) of the wiring / piping material holder 100, is defined as the erection direction.

[0028] As shown in FIG. 1 to FIG. 3, in the initial state of the wiring / piping material holder 100 (not holding the wiring / piping material P), an opening 103 for introducing the wiring / piping material P is formed between the tip of the first holding piece 110 and the tip of the second holding piece 120. A holding space 101 for holding the wiring / piping material P is defined inside the first holding piece 110 and the second holding piece 120, communicating with the opening 103. Then, the first holding piece 110 and the second holding piece 120 rotate or displace relatively around the hinge 130, and the tip portion of the first holding piece 110 and the tip portion of the second holding piece 120 overlap with each other, so that an annular holding space 101 surrounding the wiring / piping material P in the circumferential direction can be formed. At this time, the second holding piece 120 overlaps with the first holding piece 110 from the outside (radially outside) of the holding space 101. This closed retaining space 101 can be maintained by engagement between the first locking portion (first locking tooth row 113) of the first retaining piece 110 and the second locking portion (second locking tooth row 123) of the second retaining piece 120. The first locking portion and the second locking portion are released from engagement by moving away from each other in a direction different from the locking direction (i.e., the radial direction). Furthermore, whether the opening portion 103 is open or closed, a hinge-side space 105 is formed between the retaining space 101 and the hinge 130 as an extra gap in which no wiring / piping material P is placed.

[0029] This hinge-side space 105 is a space for allowing bending displacement of the base end of the first holding piece 110 and the base end of the second holding piece 120 around the hinge 130, and is therefore necessarily formed inside the wiring / piping material holder 100. In conventional wiring / piping material holders, such a hinge-side space acts as an escape space that invites bending deformation or displacement of the wiring / piping material when the wiring / piping material P is fastened with a relatively strong pressing force, and may cause problems in the installation of the wiring / piping material P.

[0030] Furthermore, the wiring / piping material holder 100 can gradually reduce the size of the holding space 101 by gradually overlapping the tip portions while maintaining the locked state. That is, by increasing the amount of overlap between the first holding piece 110 and the second holding piece 120, the amount of locking between the first locking part and the second locking part increases, or the relative locking positions of the first locking part and the second locking part change. Fig. 7 is a schematic cross-sectional view of the wiring / piping material holder 100 showing a state in which the first holding piece 110 and the second holding piece 120 are completely overlapped to reduce the holding space 101 to the smallest extent.

[0031] Each of the components of the wiring / piping material holder 100 of this embodiment will be described in detail below.

[0032] The first holding piece 110 extends from the base end side to the tip end side and is composed of a block-shaped wall portion located from the base end side to the center and an arm-shaped wall portion erected on the tip side of the block-shaped wall portion. This arm-shaped wall portion forms the tip portion of the first holding piece 110. A thin hinge 130 is connected to the base end of the block-shaped wall portion of the first holding piece 110. The first holding piece 110 includes a base portion 111 as a base to be fixed to a structure, a first 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 a first locking portion (first locking tooth row 113) for maintaining the surrounding of the wiring / piping material P by the holding space 101.

[0033] As shown in FIG. 5, the base 111 extends in the extension direction of the first holding piece 110, and has a first side 111a on the right side in the extension direction when viewed from the front and a second side 111b on the left side in the extension direction when viewed from the front. Here, the first side 111a and the second side 111b are both edges of the first holding piece 110 when viewed from the front. A flat fixing surface 111c is defined on the bottom surface of the base 111. As shown in FIG. 5, a recess 111d for accommodating the head of the fixing screw 15 is provided at approximately the center of the extension direction of the base 111. An insertion portion 114 is formed at the bottom of the recess 111d, which penetrates the base 111 vertically and through which the shaft portion of the screw 15 is inserted when fixing to a structure.

[0034] The insertion portion 114 is configured to allow the shank of the screw 15 to be inserted and the screw 15 to be screwed into a portion of the structure to which the wiring / piping material holder 100 (or the base portion 111) is to be fixed. The insertion portion 114 is also configured to be able to temporarily support or temporarily fix the tip portion of the shank of the screw 15. Specifically, the opening of the insertion portion 114 on the side where the screw 15 is introduced (the side facing away from the fixing surface 111c) is narrower than the diameter of the shank of the screw 15. With this configuration, when the tip of the shank of the screw 15 is inserted (or pressed into) the insertion portion 114, the shank of the screw 15 is pressed against the narrow opening edge of the insertion portion 114 and temporarily held. Then, the screw 15 can be held in an upright position approximately parallel to the screwing direction without falling out in the screw-retracting direction (counter-screw-in direction). That is, the insertion portion 114 has a temporary holding portion (narrowed opening edge) that temporarily holds the inserted screw 15 in a state that prevents linear movement in the screw forward / backward direction, and allows screw forward movement.

[0035] The first gripping portion 112 has an arc-shaped recess above the base 111, extending in the direction from the base end to the tip of the first holding piece 110, so as to grip the wiring / piping material P. At the tip side of the first holding piece 110, a part of the first gripping portion 112 rises from the base 111. The first 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 second holding piece 120. This curved surface is determined as a first arc portion. The arc shape of the first arc portion is determined to match the circumference of the corresponding maximum diameter (i.e., the outer peripheral shape of the wiring / piping material PL). In other words, the curvature of the first arc portion corresponds to the circle of the corresponding maximum diameter. In addition, the first arc portion has an arc-shaped plate-shaped rib 112a that enters into the valley of the wiring / piping material P, which is a corrugated flexible tube, and engages the wiring / piping material P in the longitudinal direction.

[0036] The first locking tooth row 113 is formed as a first locking part on the outer surface of the arm-shaped wall of the first holding piece 110, which is curved in an arc shape, and is made up of a plurality of locking teeth formed continuously in the direction of progression of the polymerization. In this embodiment, two rows of the first locking tooth row 113 are aligned in the circumferential direction and provided on both sides of the width direction of the first holding piece 110, spaced apart from each other. Each of the first locking tooth rows 113 extends over most of the circumferential direction of the outer surface of the arm-shaped wall. Each of the locking teeth constituting the first locking tooth row 113 has a sloping surface on the tip side and a locking surface on the opposite side that is erected substantially perpendicularly from the outer surface of the arm-shaped wall, forming a sawtooth shape. The first locking tooth row 113 allows movement in only one direction with respect to the sawtooth-shaped locking teeth of the second locking tooth row 123 described later, and acts to lock in the other direction. The first locking tooth row 113 has a larger number of locking teeth than the second locking tooth row 123. The greater the number of locking teeth constituting the first locking tooth row 113, the more it is possible to maintain the engagement between the first locking piece 110 and the second locking piece 120 while reducing the retaining space 101. In other words, the maximum overlapping amount of the first locking piece 110 and the second locking tooth row 120 is determined by the number of locking teeth of either the first locking tooth row 113 or the second locking tooth row 123, whichever has the greater number of locking teeth.

[0037] A flat dividing wall 115 is provided on the curved outer surface of the arm-shaped wall of the first holding piece 110. The dividing wall 115 is formed on the tip side of the first holding piece 110 and extends in the tip side region of the curved outer surface at the center in the width direction of the arm-shaped wall. The dividing wall 115 is a wall portion that rises at a right angle to the bottom surface of the first holding piece 110. The dividing wall 115 is formed between the two rows of the first locking teeth 113 and is arranged so as to divide the first locking teeth 113 into two in the width direction. This dividing wall 115 enters a through portion 125 described later and functions as a restricting portion that restricts the second holding piece 120 from shifting in the width direction.

[0038] 3(a) and 6, both side surfaces of the dividing wall 115 and the two rows of the first locking teeth 113 are spaced apart from each other, and a groove 116 is provided between them. The groove 116 is a region recessed relatively to the first locking teeth 113, and is a long and narrow passage extending in the circumferential direction in a region on the tip side of the arm-shaped wall portion formed beside each first locking teeth 113. As will be described later, the groove 116 functions as a guide passage that guides the progress of the second holding piece 120 in the overlapping direction, or as a receiving recess that receives the protruding groove 124 of the second holding piece 120.

[0039] The second holding piece 120 is made of a band extending in an arch shape from the base end side to the tip end side. The second holding 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. A thin hinge 130 is connected to the base end portion of the second holding piece 120. The curved shape of the tip end portion of the second holding piece 120 corresponds to the curved shape of the outer surface of the arm-shaped wall portion of the first holding piece 110 so as to overlap the tip end portion of the first holding piece 110.

[0040] The tip portion of the second holding piece 120 is provided with a separation piece 121 separated in the width direction within a range of a predetermined length from the tip in the circumferential direction. The two separation pieces 121 have free ends independent of each other. One of the two separation pieces 121 and the other separation piece can be elastically deformed inward and outward in the radial direction around their base ends, independent of each other. The two separation pieces 121 are formed side by side in the width direction perpendicular to the extension direction of the second holding piece 120, and are divided in the width direction by a through portion 125 of a predetermined width. The through portion 125 has a width that allows the partition wall 115 of the first holding piece 110 to be inserted therethrough. The two separation pieces 121 are also elastically displaceable in the direction away from each other (width direction) since their tips are separated by the through portion 125.

[0041] The through-hole 125 is an elongated hole extending in a direction intersecting the screwing direction at the tip side of the second holding piece 220. The through-hole 125 is positioned so as to communicate with or overlap with the insertion part 114 of the base part 111 in a plan view (seen from the screwing direction). In addition, there is no obstacle such as a wall between the through-hole 125 and the insertion part 114 that may impede the insertion of the tool T. Furthermore, the through-hole 125 extends to the tip edge of the second holding piece 120 along the circumferential direction, so that one end of the elongated hole in the longitudinal direction becomes an open end, and the other end opposite thereto becomes a closed end. The region on the tip (one end) side of the through-hole 125 is relatively narrower than the region on the base (other end) side. In other words, the through-hole 125 is composed of a wide region on the base end side and a narrow region on the tip side.

[0042] The opposing inner surfaces of the wide region of the through-hole portion 125 form a tool attachment portion 126 that is attached to the shaft of the tool T so as to prevent the wiring / piping material holder 100 from moving relatively. The tool attachment portion 126 is located on the front side of the insertion portion 114 in the screwing direction of the screw 15, and is configured to attach to the shaft of the tool T so as to prevent the wiring / piping material holder 100 from falling relatively due to its own weight, and to allow the tool T to be screwed into the screw 15 inserted into the insertion portion 114 while maintaining a temporary holding state due to the attachment. Here, the distance between the opposing inner surfaces of the wide region that forms the tool attachment portion 126 is determined to be smaller than the outer diameter of the shaft of the tool T (corresponding to the size of the insertion portion 114 and the screw 15), and to be capable of sandwiching and pressing the shaft of the tool T between the opposing inner surfaces by elastically displacing the separation pieces 121 in the direction away from each other. That is, in this embodiment, the tool attachment part 126 is physically attached to the tool T by a force that prevents the tool T from falling by its own weight, using the elastic restoring force of the opposing inner surfaces of the through-hole (long hole) 125. Similarly, the tool attachment part 126 can also prevent the tool T from freely sliding within the through-hole 125. On the other hand, the tool attachment part 126 is configured to allow relative rotation and relative movement between the tool T and the base part 111 in a temporary holding state in which the tool T is attached to the tool attachment part 126. Specifically, when a predetermined force is applied to the tool T by a user in a state in which the tool T is clamped by the tool attachment part 126, the shaft part of the tool T can rotate relatively within the through-hole 125, tilt within the through-hole 125, and slide in the longitudinal direction of the through-hole 125 (wide region) while maintaining the attachment state with the tool attachment part 126. Note that, in this embodiment, the tool attachment part 126 can attach tools T having different thicknesses as long as they are within a range in which the separation piece 121 can be elastically deformed.

[0043] In the narrow region of the through portion 125, a restricting wall portion 127 is formed, which protrudes in a step shape from the opposing inner surface of the long hole relative to the inner surface of the wide region. The narrow region and the restricting wall portion 127 extend continuously to the opening edge at the tip of the through portion 125. The restricting wall portion 127 protrudes further from the inner surface of the long hole relative to the tool attachment portion 126, and restricts the tool T from sliding in the long hole from the tool attachment portion 126 (wide region) toward the open end. More specifically, the distance between the opposing inner surfaces of the narrow region forming the restricting wall portion 127 is smaller than the outer diameter of the shaft portion of the tool T and the distance between the opposing inner surfaces of the wide region, and is determined so as to prevent the shaft portion of the tool T from sliding in. The end face (step) on the base end side of the restricting wall portion 127 abuts against the tool T, thereby restricting the shaft portion of the tool T from sliding from the tool attachment portion 126 toward the open end.

[0044] The second holding piece 120 has a second holding portion 122 which forms an arc-shaped recess on its inner surface for holding the wiring / piping material P, and a second locking portion (second locking tooth row 123) for maintaining the wiring / piping material P surrounded by the holding space 101.

[0045] The second gripping portion 122 has an arc-shaped recess along the extension direction from the base end to the tip end of the second holding piece 120 so as to grip the wiring / piping material P. The second gripping portion 122 is formed as a curved surface that is approximately arc-shaped in cross section on the inner surface of the recess facing the first holding piece 110. This curved surface is determined as the second arc portion. The arc shape of the second arc portion is determined to match the circumference of the corresponding maximum diameter (i.e., the outer peripheral shape of the wiring / piping material PL). In other words, the curvature of the second arc portion corresponds to the circle of the corresponding maximum diameter. In addition, the second arc portion has an arc plate-shaped rib 122a that enters the valley portion of the wiring / piping material P, which is a corrugated flexible tube, and engages the wiring / piping material P in the longitudinal direction.

[0046] On the inner surface of the tip portion of the second holding piece 120, a second locking tooth row 123 consisting of a plurality of (three in this example) locking teeth formed consecutively in the direction of progression of the overlapping is formed as a second locking portion. The second locking portion is provided on each of the two separation pieces 121. That is, the two rows of the second locking tooth rows 123 are aligned in the circumferential direction and provided on both sides of the second holding piece 120 in the width direction, spaced apart from each other. The two rows of the second locking tooth rows 123 are respectively arranged at widthwise positions that can face the two rows of the first locking tooth rows 113 in the radial direction. In addition, each of the second locking tooth rows 123 is formed on the tip of each separation piece 121 and is composed of three locking teeth. Each of the locking teeth constituting the second locking tooth row 123 has a sawtooth shape with an inclined surface on the tip side and a locking surface that stands up approximately vertically from the inner surface of the separation piece 121 on the opposite side. When the tip portions of the first retaining piece 110 and the second retaining piece 120 overlap, the locking teeth of the first locking tooth row 113 and the second locking tooth row 123 engage with each other with a click in the radial direction. At this time, the inclined surfaces of the locking teeth slide against each other, allowing relative movement in a direction in which the overlapping progresses and the holding space 101 is reduced. When the overlapping progresses, when one locking tooth overcomes the other opposing locking tooth by the sliding of the inclined surfaces and then engages with the locking tooth, the user can feel a clicking sensation and sound due to the engagement of the locking teeth. On the other hand, the locking surfaces of the locking teeth are engaged with each other, so that the relative movement in a direction in which the overlapping progresses and the holding space 101 is expanded is restricted. In addition, the second locking tooth row 123 is displaced radially outward relative to the first locking tooth row 113, and the locked state by both locking teeth is released.

[0047] As shown in Figs. 1(b), 4 and 6, a convex ridge portion 124 is formed as a guide convex portion on the inner side in the width direction of the second locking tooth row 123. The convex ridge portion 124 extends along the arrangement from the first locking tooth on the tip side of the second locking tooth row 123 to the third locking tooth. In other words, the convex ridge portion 124 has a length that spans all of the locking teeth of the second locking tooth row 123. The convex ridge portion 124 protrudes from the inner surface of the widthwise inner edge of each separation piece 121 and is formed integrally with the widthwise inner side portion of the three locking teeth. Here, the protruding height of the convex ridge portion 124 and the protruding height of the locking teeth are approximately the same.

[0048] The convex streak portion 124 is configured to be received in the concave streak portion 116 formed beside the first locking tooth row 113 of the first holding piece 110. When the first holding piece 110 and the second holding piece 120 start to overlap, the concave streak portion 116 is accommodated in the convex streak portion 124 as a receiving concave portion, and the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123 start to engage with each other. Then, as the overlapping of the first holding piece 110 and the second holding piece 120 progresses, the convex streak portion 124 is guided by the concave streak portion 116, which is a guide passage, and can slide. By maintaining the convex streak portion 124 within the concave streak portion 116, the separation pieces 121 are prevented from shifting in the width direction during the operation of advancing the overlapping.

[0049] Further, each of the separation pieces 121 of the second holding piece 120 is provided with a release operation part 128 that protrudes outward in the width direction at its tip. That is, the release operation part 128 protrudes on both sides in the arrangement direction of the second holding piece 120. The release operation part 128 is configured to be operated by a user to lift the release operation part 128 outward (radially) of the holding space 101 with a finger or a shaft-shaped operating tool (such as a flathead screwdriver), thereby separating the second locking part from the first locking part in the radial direction of the wiring / piping material P, thereby releasing the locking of the first locking part and the second locking part. In this embodiment, the release operation part 128 is a rectangular knob, but the shape thereof can be selected arbitrarily. Moreover, the release operation part 128 protrudes along the arrangement direction so as to face the outer circumferential surface of the wiring / piping material P to be held via a gap. The gap is formed to a size that allows an operating tool to be inserted between the outer circumferential surface of the wiring / piping material P held in the holding space 101 and the release operating part 128. In addition, since the two separation pieces 121 are elastically deformable independently of each other via the through-holes 125, operating one of the release operating parts 128 operates to release only one of the separation pieces 121 from the engagement.

[0050] The hinge 130 connects the base ends of the first holding piece 110 and the second holding piece 120, and is configured to rotate the first holding piece 110 and the second holding piece 120 in the opening and closing directions. The hinge 130 is a thin piece that forms a relatively thin portion with respect to the first holding piece 110 and the second holding piece 120, and can elastically deform preferentially with respect to other portions. When the first holding piece 110 and the second holding 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 first holding piece 110 and the second holding piece 120 are displaced in a direction in which the opening portion 103 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 105 is formed inside the hinge.

[0051] The auxiliary piece 140 is provided to prevent the wiring / piping material P held in the holding space 101 from escaping into the hinge side space 105. The auxiliary piece 140 is an arc-shaped strip rising from the inner surface of the first holding piece 110 with a protruding length toward the inner surface of the second holding piece 120 with its tip as a free end. The auxiliary piece 140 is arranged so as to be located between the wiring / piping material P arranged in the holding space 101 and the hinge 130. In particular, the auxiliary piece 140 is connected to the base end of the first arc portion and is arranged to be biased toward the hinge 130 side from the center of the holding space 101 of the first holding piece 110. In this embodiment, the auxiliary piece 140 rises into the holding space 101 when holding the corresponding minimum diameter wiring / piping material PS. In addition, the auxiliary piece 140 is arranged so as to face the inner surface of the tip portion of the first holding piece 110. A space is formed on the hinge 130 side of the auxiliary piece 140 to allow the auxiliary piece 140 to tilt toward the hinge 130. This space is a retreat space for retreating the inner surface of the auxiliary piece 140 (the side that abuts against the wiring / piping material P) to a position where it joins with the inner surface of the second holding piece 120. Furthermore, the distance between the tip of the auxiliary piece 140 and the tip of the first holding piece 110 is smaller than the diameter of the maximum diameter wiring / piping material PL.

[0052] The auxiliary piece 140 includes a base end 141 that is elastically deformable at its base end, and an abutment portion 142 that can abut against the outer circumferential surface of the wiring / piping material P. The base end 141 is a relatively thin portion of the auxiliary piece 140, and assists the elastic tilting of the auxiliary piece 140. The abutment portion 142 has an arc-shaped curved surface that faces the tip side of the first holding piece 110 to abut against the outer circumferential surface of the wiring / piping material P. The curved surface of the abutment portion 142 is determined to match the circumference of the corresponding maximum diameter (i.e., the outer circumferential shape of the wiring / piping material PL). In other words, the curvature of the curved surface of the abutment portion 142 corresponds to the circle of the corresponding maximum diameter. That is, the first arc portion, the second arc portion, and the curved surface of the abutment portion 142 have the same curvature, and are configured to be able to be positioned on the same circumference of the diameter of the wiring / piping material PL. Further, the auxiliary piece 140 has a circular arc-shaped rib 142a formed on the outer surface on the hinge 130 side so as to protrude therefrom.

[0053] In addition, the auxiliary piece 140 is disposed on the tip side of the first holding piece 110 from the holding position of the wiring / piping material P so that when the wiring / piping material P of a predetermined diameter (including the wiring / piping material PS of the corresponding minimum diameter) is gripped, the auxiliary piece 140 abuts against the outer peripheral surface of the wiring / piping material P and tilts toward the hinge 130. As shown by the imaginary line in FIG. 4, the abutting portion 142 is elastically displaceable so as to tilt from the initial position toward the hinge 130 around the base end portion 141. When the wiring / piping material P of a size ranging from the corresponding minimum diameter to the maximum diameter is placed in the holding space 101, the auxiliary piece 140 elastically tilts toward the hinge 130 as the wiring / piping material P is tightened, and the auxiliary piece 140 is pressed against the wiring / piping material P by the elastic force. On the other hand, when wiring / piping material PL of the corresponding maximum diameter is introduced into the holding space 101, the auxiliary piece 140 can also act to temporarily hold the wiring / piping material PL by clamping the wiring / piping material PL in cooperation with the inner surface of the tip portion of the first holding piece 110 that faces the inner surface of the abutment portion 142.

[0054] Furthermore, the auxiliary piece 140 is configured such that the tip of the auxiliary piece 140 (or the periphery of the rib 142a) comes into contact with the inner surface of the second holding piece 120 when the holding space 101 in which the wiring / piping material P is arranged is reduced. For example, when holding a wiring / piping material PS of a corresponding minimum diameter, the auxiliary piece 140 is pressed toward the hinge 130 by the wiring / piping material PS, and retreats toward the hinge 130 and assumes an upright position. When the auxiliary piece 140 is in the retreated position, it is pressed from the hinge 130 side toward the tip of the second holding piece 120 by the inner surface of the second holding piece 120 (see FIG. 17(c)). This pressing force can also move the auxiliary piece 140 from the retreated position toward the tip of the second holding piece 120. In this way, the position and protruding length of auxiliary piece 140 are determined so that when wiring / piping material P of a predetermined diameter is held in holding space 101, the tip of auxiliary piece 140 (or the peripheral edge of rib 142a) tilted to a retracted position in accordance with the diameter of the wiring / piping material P abuts or is pressed against the inner surface of second holding piece 120 (or the inner surface of the second arc portion).

[0055] Next, with reference to Fig. 8 to Fig. 11, an installation structure 10 in which wiring / piping material PS of a corresponding minimum diameter is held and arranged in a construction material 11 (structure) by the wiring / piping material holder 100 of this embodiment will be described. Fig. 8 is a schematic perspective view of the installation structure 10. Fig. 9 is a schematic front view of the installation structure 10. Fig. 10 is a DD cross-sectional view of the installation structure 10. Fig. 11 is an EE cross-sectional view of the installation structure 10.

[0056] As shown in Fig. 8 and Fig. 9, in the installation structure 10 of this embodiment, the structure is a columnar construction material 11 that stands vertically, and a wiring / piping material holder 100 is fixed to the front side (installation surface) of the construction material 11. The wiring / piping material PS is held by the wiring / piping material holder 100 and is installed so that its installation direction is along the vertical direction. In the present invention, the construction is not limited to construction materials or wall materials, but refers to all objects to which a fastener is fixed, and may be, for example, a fixed base separate from the construction material. Furthermore, the screwed portion is not limited to a flat installation surface, and may be a screw hole or the like.

[0057] As shown in Fig. 11, in the installation structure 10, the fixing surface 111c of the base 111 of the wiring / piping material holder 100 abuts against the side surface of the construction material 11, and the screw 15 penetrates the insertion portion 114, thereby fixing the wiring / piping material holder 100 to the construction material 11. At this time, the head of the screw 15 is received in the recess 111d of the base 111, and the shaft is screwed into the screwed portion of the construction material 11. The wiring / piping material holder 100 is fixed in a position in which its width direction is aligned vertically.

[0058] In the installation structure 10, the wiring / piping material PS is held in a closed holding space 101 of the wiring / piping material holder 100. As shown in FIG. 10, the tip portions of the first holding piece 110 and the second holding piece 120 overlap each other, and the second locking teeth row 123 meshes with the first locking teeth row 113 from the radially outer side, thereby maintaining the closed state of the holding space 101. In the installation structure 10 that holds the wiring / piping material PS having a corresponding minimum diameter, three locking teeth of the second locking teeth row 123 engage with the three locking teeth on the rearmost side of the first locking teeth row 113 so that the overlap amount of the first holding piece 110 and the second holding piece 120 is maximized. The locking surfaces of the first locking teeth row 113 and the second locking teeth row 123 are locked in the circumferential direction, thereby restricting the second holding piece 120 from moving relative to the first holding piece 110 in a direction in which the overlap retreats. As a result, the holding space 101 surrounding the wiring / piping material PS is kept at a minimum.

[0059] In the installation structure 10, as shown in FIG. 10, the arcuate portion of the first gripping portion 112, the arcuate portion of the second gripping portion 122, and the abutment portion 142 of the auxiliary piece 140 are each pressed against the outer peripheral surface (outer peripheral surface of the ridge portion) of the wiring / piping material PS, thereby gripping the wiring / piping material PS.

[0060] Moreover, the auxiliary piece 140 is positioned between the outer peripheral surface of the wiring / piping material PS and the hinge 130. The auxiliary piece 140 blocks communication between the holding space 101 and the hinge-side space 105. Furthermore, the tip of the auxiliary piece 140 (the periphery of the rib 142a) engages with the inner surface of the second gripping portion 122 of the second holding piece 120 in a position retreated from the original position toward the hinge 130 side. The auxiliary piece 140 is pressed from the hinge 130 side toward the center of the holding space 101 (the tip side of the first holding piece 110 or the second holding piece 120) by the inner surface of the second gripping portion 122. This pressing force makes the wiring / piping material PS more firmly held by the three points of the first holding piece 110, the second holding piece 120, and the auxiliary piece 140. And because the auxiliary piece 140 supports the wiring / piping material PS from the hinge 130 side, it does not tilt further into the hinge-side space 105. Therefore, the auxiliary piece 140 prevents the wiring / piping material PS from escaping from the retaining space 101 to the hinge-side space 105.

[0061] The locked state of the wiring / piping material holder 100 is formed by the second locking tooth rows 123 formed on the two separation pieces 121 of the second holding piece 120 and the two rows of the first locking tooth rows 113 engaging with each other independently. In other words, even if one separation piece 121 is unintentionally displaced radially outward and the engagement of one set of the first locking tooth rows 113 and the second locking tooth rows 123 is released, the engagement of the other set can be maintained. Furthermore, in the installation structure 10, the dividing wall 115 of the first holding piece 110 enters the penetration portion 125 of the second holding piece 120, and the convex ridge portion 124 formed beside the second locking tooth rows 123 is housed in the concave ridge portion 116, so that the first holding piece 110 and the second holding piece 120 are restricted from shifting in the arrangement direction (width direction) of the wiring / piping material PS. That is, in the installation structure 10, the wiring / piping material PS is firmly held by the wiring / piping material holder 100.

[0062] FIG. 12 shows an installation structure 10-2 of another form in which a wiring / piping material PL having a maximum diameter among the corresponding wiring / piping materials P is arranged in the installation structure 10 of FIG. 10. In the installation structure 10-2, the wiring / piping material PL is held in a closed holding space 101 of the wiring / piping material holder 100. The tip portions of the first holding piece 110 and the second holding piece 120 overlap each other, and the second locking teeth row 123 meshes with the first locking teeth row 113 from the radial outside, thereby maintaining the closed state of the holding space 101. In the installation structure 10 that holds the wiring / piping material PL having a corresponding maximum diameter, three locking teeth of the second locking teeth row 123 engage with the three locking teeth on the most distal side of the first locking teeth row 113 so that the amount of overlap between the first holding piece 110 and the second holding piece 120 is minimized. The locking surfaces of the first locking tooth row 113 and the second locking tooth row 123 are locked in the circumferential direction, thereby restricting the second holding piece 120 from moving relative to the first holding piece 110 in the direction in which the overlap retreats. As a result, the holding space 101 surrounding the wiring / piping material PL is maintained in a maximum state.

[0063] As shown in FIG. 12, the arc portion of the first gripping portion 112, the arc portion of the second gripping portion 122, and the abutting portion 142 of the auxiliary piece 140 abut against the outer circumferential surface (the outer circumferential surface of the crest portion) of the wiring / piping material PL, thereby holding the wiring / piping material PL. At this time, the first arc portion, the second arc portion, and the curved surface of the abutting portion 142 are located on the same circumference that is approximately the same as the outer circumferential surface (the crest portion) of the wiring / piping material PL. Therefore, the wiring / piping material PL is stably held by the wiring / piping material holder 100 so that it does not move freely within the holding space 101. When holding the wiring / piping material PL having the corresponding maximum diameter, the holding position of the wiring / piping material PL is determined to be one place within the holding space 101, and there is no need to check the position of the wiring / piping material PL or align the wiring / piping material PL.

[0064] Additionally, the auxiliary piece 140 is positioned between the outer peripheral surface of the wiring / piping material PL and the hinge 130. The auxiliary piece 140 is tilted to a position close to the hinge 130. The auxiliary piece 140 then blocks communication between the holding space 101 and the hinge side space 105. Furthermore, when holding the wiring / piping material PL with the maximum diameter, the auxiliary piece 140 retreats to a position where it is not pressed (or moved) toward the tip by the inner surface of the second holding piece 120.

[0065] 13 to 15, a method for fixing the wiring / piping material holder 100 to the construction material 11 using a tool T and screws 15 will be described. The tool T is a general screwdriver, but it may also be a power tool or the like.

[0066] First, as shown in FIG. 13, the screw 15 is provisionally fixed to the insertion portion 114 of the wiring / piping material holder 100. In particular, the screw 15 is disposed in the holding space 101 through the opening 103 from the radial direction, or through the opening between the first holding piece 110 and the second holding piece 120 from the arrangement direction. Then, the screw 15 can be provisionally fixed to the insertion portion 114 in a standing state along the screwing direction by pressing the screw 15 into the narrowed opening of the insertion portion 114 by hand or the like. At this time, it is preferable that the tip of the screw 15 does not protrude from the fixing surface 111c of the base 111. Next, while holding the wiring / piping material holder 100, the tool T is operated so as to insert the tip of the shaft of the tool T into the through portion 125 (wide area). When the tool T is inserted into the through portion 125, the separation pieces 121 are elastically deformed in a direction in which they move away from each other, and the width of the through portion 125 is expanded. The elastic restoring force of the separation piece 121 causes the tool attachment portion 126 on the inner surface of the through-hole 125 to be attached (clamped) to the shaft of the tool T. When the tool T is inserted into the through-hole 125, a temporary holding state with the tool T is formed at the same time. While maintaining this attachment state, the tip of the shaft of the tool T is engaged with the drive portion (cross groove) of the head of the screw 15. At this time, since the head of the screw 15 faces the user's operation side space from the through-hole 125 along the screwing direction, it is easy for the user to operate to engage the tool T with the screw 15. Then, the tool T is attached to the tool attachment portion 126, the screw 15 is temporarily fixed to the insertion portion 114, and the tip of the tool T is engaged with the head of the screw 15, and the state can be maintained. In this process, instead of temporarily holding the screw 15 in the insertion portion 114, the screw 15 may be magnetically attached to the tip of the tool T to temporarily hold the screw 15 at the tip of the tool T.

[0067] As shown in FIG. 14, the user holds the wiring / piping material holder 100 and the screw 15 together by gripping the handle of the tool T. At this time, no matter which direction the user faces the tool T, the wiring / piping material holder 100 can be prevented from falling off the tool T under its own weight (including the weight of the screw 15) due to the elastic adhesion force of the tool attachment part 126. Therefore, the user only needs to grip the tool T, and does not need to grip the wiring / piping material holder 100 and the screw 15 with his / her hands. Then, the user holds the tool T and positions the fixing position of the wiring / piping material holder 100 while facing the fixing surface 111c of the wiring / piping material holder 100 against the installation surface of the construction material 11, and maintains that posture so as to determine the installation direction of the wiring / piping material P.

[0068] Next, as shown in FIG. 15, while maintaining the wiring / piping material holder 100 at a fixed position in a predetermined posture, the tool T is rotated to screw the screw 15 into the screwed portion of the construction material 11 through the insertion portion 114. Preferably, in the screwing process, the user places his / her hand on the wiring / piping material holder 100 to cause the tool T to spin freely inside the penetration portion 125, preventing the wiring / piping material holder 100 from following (rotating together with) the rotation of the tool T, and enabling the screwing operation to be performed while maintaining the posture at the time of (planned) completion of fixing. Note that when the screw 15 is screwed into the screwed portion, the wiring / piping material holder 100 may be rotated together with the screw 15 while the posture of the wiring / piping material holder 100 is adjusted. Once the screw 15 has entered the screwed portion, the wiring / piping material holder 100 will not fall off even if it rotates (together with the tool T). Then, by screwing the screw 15 firmly in until the head of the screw 15 is pressed against the periphery of the insertion portion 114, the wiring / piping material holder 100 can be fixed to the construction material 11. After the wiring / piping material holder 100 has been fixed to the construction material 11, force is applied to the tool T to pull it out of the penetration portion 125, thereby removing the tool T from the tool attachment portion 126.

[0069] In the wiring / piping material holder 100 of this embodiment, the through-hole 125 (tool attachment part 126) extends in an elongated hole shape, so that the tool T can be operated at an angle relative to the fixing surface 111c (or the installation surface). As shown in Fig. 16, it is also possible to set the screwing direction of the screw 15 at an angle relative to the installation surface of the construction material 11, and rotate the tool T with it attached to the tool attachment part 126 to screw in the screw 15 at a predetermined angle.

[0070] 17, an example will be given of each step of a method for holding a wiring / piping material P with the wiring / piping material holder 100. Here, the wiring / piping material P is a wiring / piping material PS with a compatible minimum diameter.

[0071] First, the open portion 103 of the wiring / piping material holder 100 is opened, and the wiring / piping material PS is inserted into the holding space 101 through the open portion 103. As shown in FIG. 17(a), the wiring / piping material PS is placed between the tip portion of the first holding piece 110 and the auxiliary piece 140. At this time, the wiring / piping material PS is sandwiched between the abutting portion 142 of the auxiliary piece 140 elastically displaced radially outward and the inner surface of the first holding piece 110. Then, the second holding piece 120 is rotated about the hinge 130 in a direction to close the open portion 103. The tip portion of the first holding piece 110 and the tip portion of the second holding piece 120 are overlapped, and the first locking tooth row 113 and the second locking tooth row 123 are engaged with each other.

[0072] As shown in FIG. 17(b), after the first engagement state is formed, the overlapping of the first holding piece 110 and the second holding piece 120 progresses, and the auxiliary piece 140 comes into contact with the inner surface of the second holding piece 120. Then, when the tightening operation is continued to reduce the holding space 101, as shown in FIG. 17(c), the auxiliary piece 140 is pressed against the inner surface of the second holding piece 120, and is moved toward the center of the holding space 101 and tilted slightly. At this time, the auxiliary piece 140 acts to bias or press the wiring / piping material PS toward the center of the holding space 101. Furthermore, when the second holding piece 120 is tightly tightened against the first holding piece 110, the overlapping amount of the first holding piece 110 and the second holding piece 120 becomes maximum, and the wiring / piping material PS can be gripped by the first holding piece 110, the second holding piece 120, and the auxiliary piece 140. In this manner, the pressing force of the auxiliary piece 140 increases due to the gradual engagement of the first and second locking parts in a direction that reduces the size of the holding space 101. As a result, the wiring / piping material P can be firmly gripped by the wiring / piping material holder 100 and stably held in the holding space 101.

[0073] When wiring / piping material P of a different diameter is installed, the engagement positions of the first locking tooth row 113 and the second locking tooth row 123 shift toward the rear end, but the basic process is the same. However, the operation of the auxiliary piece 140 changes depending on the diameter of the wiring / piping material P. For example, when holding a wiring / piping material PL of the maximum compatible diameter, the auxiliary piece 140 is completely retracted toward the hinge 130, so that it is not pressed toward the tip side by the inner surface of the second holding piece 120 and is not moved toward the center of the holding space 101.

[0074] The following describes the operation and effect of the wiring / piping material holder 100 according to one embodiment of the fixing device of the present invention.

[0075] According to the wiring / piping material holder 100 of this embodiment, the tool attachment portion 126 is disposed on the front side of the insertion portion 114 in the screwing direction of the screw 15, and is attached to the tool T so as to prevent the wiring / piping material holder 100 from falling due to its own weight. The tool attachment portion 126 is also configured so that the tool T can be operated to screw in the screw 15 inserted into the insertion portion 114 while maintaining the state of being temporarily held by the tool T. This allows the user to rotate the tool T and screw the screw 15 into the structure 11 in the temporarily held state in which the tool T and the wiring / piping material holder 100 are attached together, without worrying about the wiring / piping material holder 100 falling. Therefore, the wiring / piping material holder 100 of this embodiment makes it easier to fix the structure using the screw 15 and the tool T.

[0076] Secondly, according to the wiring / piping material holder 100 of this embodiment, the tip portion of the first holding piece 110 and the tip portion of the second holding piece 120 overlap with each other to form an annular holding space 101 surrounding the wiring / piping material P. In particular, the second holding piece 120 is displaced from the outside of the holding space 101 so as to overlap with the first holding piece 110, so that an engagement state of the first locking portion (first locking tooth row 113) on the outer surface of the second holding piece 120 and the second locking portion (second locking tooth row 123) on the inner surface of the second holding piece 120 is formed and maintained. That is, the first holding piece 110 and the second holding piece 120 can hold the wiring / piping material P by a simple and intuitive operation of overlapping the second holding piece 120 with the first holding piece 110 from the outside of the holding space 101. On the other hand, the first locking portion and the second locking portion are relatively easily released from engagement by moving away from each other in a direction different from the engagement direction. In contrast, the wiring / piping material holder 100 of this embodiment has two separation pieces 121, 121 arranged side by side at the tip of the second holding piece 120, each having a free end independent of the other via a through-hole 125 (which also serves as a tool attachment part 126), and each separation piece 121 is provided with a second locking tooth row 123, thereby preventing the first locking part and the second locking part from being easily released unintentionally. That is, the second locking tooth row 123 of one separation piece 121 and the second locking tooth row 123 of the other separation piece 121 can independently form an engagement state with each of the opposing first locking tooth rows 113, and can be separated from each of the first locking tooth rows 113. That is, to release the holding of the wiring / piping material P, it is necessary to operate the two separation pieces 121, 121 so as to separate the second locking part from the first locking part. Even if a force in a direction that separates the first and second locking portions is suddenly applied to one of the two separation pieces 121 and the locked state is released, the locked state of the other separation piece 121 is maintained, so the holding of the wiring / piping material P is prevented from being completely released. Since a situation in which a force in a direction that separates the first and second locking portions is suddenly applied to both of the two separation pieces 121, 121 is extremely rare, the configuration of this embodiment effectively prevents the holding of the wiring / piping material P from being suddenly released.Therefore, the wiring / piping material holder 100 of the present embodiment stably maintains the holding state of the wiring / piping material P and enables the wiring / piping material P to be held with simpler operation.

[0077] Thirdly, according to the wiring / piping material holder 100 of this embodiment, the tip side of the first holding piece 110 and the tip side of the second holding piece 120 overlap to form an annular holding space 101 surrounding the wiring / piping material P, and by increasing the amount of overlap and reducing the holding space 101, it is possible to hold wiring / piping materials P (PS, PL) of different diameters. When the first holding piece 110 and the second holding piece 120 are overlapped to hold wiring / piping material P of a predetermined diameter, a hinge side space 105 as a gap is inevitably formed between the hinge 130 and the holding space 101. In response to this, an auxiliary piece 140 is provided that rises from the inner surface of the first holding piece 110 into the holding space 101 with its tip as a free end. The auxiliary piece 140 is located between the wiring / piping material P arranged in the holding space 101 and the hinge 130, and has an abutting portion 142 that can abut against the outer circumferential surface of the wiring / piping material P. The auxiliary piece 140 blocks communication between the holding space 101 and the hinge-side space 105, and abuts against the wiring / piping material P arranged in the holding space 101 from the hinge 130 side. This prevents the held wiring / piping material P from escaping from the holding space 101 to the hinge-side space 105. Furthermore, the auxiliary piece 140 is configured so that a tip of the auxiliary piece 140 abuts against an inner surface of the second holding piece 120 when the overlapping of the first holding piece 110 and the second holding piece 120 is advanced to reduce the holding space 101 in order to hold the wiring / piping material P. The auxiliary piece 140 can support the wiring / piping material P by urging it from the hinge-side space 105 in conjunction with the overlapping movement of the first holding piece 110 and the second holding piece 120. Therefore, the wire / piping material holder 100 of this embodiment can more stably hold wire / piping materials P (PS, PL) having different diameters.

[0078] Fourthly, according to the wiring / piping material holder 100 of this embodiment, the second holding piece 120 is provided with a release operation portion 128 that protrudes in the installation direction so as to face the outer circumferential surface of the wiring / piping material P to be held via a gap. That is, since the release operation portion 128 protrudes in the installation direction from the second holding piece 120 that extends in the circumferential direction of the wiring / piping material P, the gap between the release operation portion 128 and the outer circumferential surface of the wiring / piping material P is opened at least in the circumferential direction of the wiring / piping material P. The user can use the gap to lift the release operation portion 128 to the outside (radial outside) of the holding space 101 with a finger or a shaft-shaped operating tool from a direction intersecting or perpendicular to the wiring / piping material P, thereby separating the second locking tooth row 123 from the first locking tooth row 113 in the radial direction of the wiring / piping material P, thereby releasing the locking of the first locking portion and the second locking portion. At this time, since there is sufficient space for the unlocking operation in the direction intersecting or perpendicular to the wiring / piping material P, the unlocking operation can be performed without interference from the wiring / piping material P extending in the installation direction. Therefore, the wiring / piping material holder 100 of this embodiment makes the unlocking operation easier.

[0079] [Variations] 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. In each modification, components indicated by three digits that have the same last two digits have the same or similar characteristics unless otherwise specified, and the description thereof will be omitted.

[0080] (1) The fixture of the present invention is not limited to the configuration of the above embodiment. In the fixture (wiring / piping material holder) of the above embodiment, the tool attachment parts are formed on the opposing inner surfaces of the elongated through-hole with one end open, and the attachment force is elastic, but the present invention is not limited to this. FIG. 18 shows a wiring / piping material holder 200 as a fixture of another embodiment of the present invention. In the wiring / piping material holder 200, the tip part of the second holding piece 210 is not divided. And the tool attachment part 226 is formed on the inner surface of the circular through-hole 225. The diameter of the through-hole 225 is the same as the outer diameter of the shaft of the tool T. As shown in FIG. 19, the shaft of the tool T fits into the through-hole 225, so that the tool T is attached to the tool attachment part 226. That is, the tool attachment part 226 utilizes the force of fitting with the tool T. With the wiring / piping material holder 200 and the screw 25 held integrally by the tool T, the tool T can be rotated within the penetration portion 225, or the tool T can be rotated together with the wiring / piping material holder 200, to screw in the screw 25. That is, the tool attachment portion 226 is disposed on the front side of the insertion portion 214 in the screwing direction of the screw 25, and is configured to attach (fit) to the tool T so as to prevent the wiring / piping material holder 200 from falling relatively due to its own weight, and to allow the tool T to be screwed into the screw 25 inserted into the insertion portion 214 while maintaining the temporary holding state due to the attachment.

[0081] (2) The fixture of the present invention is not limited to the configuration of the above embodiment. In the fixture (wiring / piping material holder) of the above embodiment, the tool attachment parts are formed on the opposing inner surfaces of the elongated through-hole with one end open, and the attachment force is elastic, but the present invention is not limited to this. FIG. 20 shows a wiring / piping material holder 300 as a fixture of another embodiment of the present invention. In the wiring / piping material holder 300, the tip part of the second holding piece 310 is not divided. And the tool attachment part 326 is formed on the inner surface of the circular through-hole 325. The diameter of the through-hole 325 is larger than the outer diameter of the shaft of the tool T. In this embodiment, the inner surface of the through-hole 325 is made of a strong magnet. That is, the tool attachment part 326 utilizes magnetic force. As shown in FIG. 21, the shaft of the tool T is magnetically attached to the inner surface of the through-hole 325, so that the tool T is attached to the tool attachment part 326. Then, in a state where the wiring / piping material holder 300 and the screw 35 are integrally held by the tool T, the tool T can be rotated in the penetration portion 325, or the tool T can be rotated together with the wiring / piping material holder 300, to screw in the screw 35. That is, the tool attachment portion 326 is disposed on the front side of the insertion portion 314 in the screwing direction of the screw 35, and is attached (magnetically attached) to the tool T so as to prevent the wiring / piping material holder 300 from falling due to its own weight, and is configured to allow the tool T to be screwed into the screw 35 inserted into the insertion portion 314 while maintaining a temporary holding state due to the attachment. Note that the tool attachment portion may be provided with an adhesive material instead of a magnet, and the adhesive force of the adhesive material may be utilized.

[0082] (3) The fixture of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the fixture is shown as a wiring / piping material holder, but the present invention is not limited to this. FIG. 22 shows a fixture 400 of another embodiment. The fixture 400 is fixed to a structure by screwing a screw 45 into a screwed portion of the structure using a tool T as both saddles. The fixture 400 has an insertion portion 414 through which the shaft of the screw 45 is inserted, and includes a base 411 fixed to the structure via the screw 45 and the insertion portion 414, and a tool attachment portion 426 arranged on the front side of the insertion portion 414 in the screwing direction of the screw 45, attached to the tool T so as to prevent the fixture 400 from falling due to its own weight, and configured to allow the tool T to be screwed into the screw 45 inserted into the insertion portion 414 while maintaining a temporary holding state due to the attachment. The bases 411, 411 are arranged on both sides of the central semicircular holding piece. An opposing wall facing the base 411 extends from an upright wall erected from an end of the base 411, and the opposing wall is formed by cutting out the through-hole 425. The tool attachment portion 426 is formed on the inner surface of the through-hole 425 which has an open end and the distance between the opposing inner surfaces of the through-hole 425 is slightly smaller than the outer diameter of the shaft of the tool T. In other words, the tool attachment portion 426 utilizes an elastic force to clamp the tool T. Moreover, the tool attachment portion 426 is provided in two places in the fixture 400.

[0083] (4) The fixture of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the fixture is shown as a wiring / piping material holder, but the present invention is not limited to this. FIG. 23 shows a fixture 500 of another embodiment. The fixture 500 is fixed to a structure as a hook by screwing a screw 55 into a screwed portion of the structure using a tool T. The fixture 500 has an insertion portion 514 through which the shaft of the screw 55 is inserted, and includes a base 511 fixed to the structure via the screw 55 and the insertion portion 514, and a tool attachment portion 526 arranged on the front side of the insertion portion 514 in the screwing direction of the screw 55, attached to the tool T so as to prevent the fixture 500 from falling relatively due to its own weight, and configured to allow the tool T to be screwed into the screw 55 inserted into the insertion portion 514 while maintaining a temporary holding state due to the attachment. A through portion 525 is drilled on the tip side of the hook extending integrally from the base 511. The tool attachment portion 526 is formed on the inner surface of the elongated hole-shaped through-hole 525, and the distance between the opposing inner surfaces of the through-hole 525 is the same as the outer diameter of the shaft portion of the tool T. In other words, the tool attachment portion 526 utilizes the force of fitting with the tool T.

[0084] (5) The fixture of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the tool attachment portion and the through-hole allow relative rotation of the tool shaft within the through-hole, but for example, if the orientation of the fixture is not specified, the tool attachment portion may be configured to rotate the fixture together with the tool without allowing relative rotation of the tool with respect to the fixture.

[0085] (6) The fixing device of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the insertion portion is configured as a through hole with a narrowed opening, but the insertion portion of the present invention is not limited to this form. For example, the insertion portion may not be pre-penetrated, and may be in a form in which the opening is blocked by a membrane or a wall and penetrated when fixed by screwing in a screw. In addition, the insertion portion may be configured in such a way that the screw cannot be temporarily held.

[0086] (7) The fixing tool of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the insertion portion is configured as a through hole with a narrowed opening, but the insertion portion of the present invention is not limited to this form. For example, the insertion portion does not have to be narrower than the outer diameter of the shank of the screw. Even in such a case, a temporary fixation state of the screw to the insertion portion can be formed. That is, when the screw is inserted into the insertion portion of the fixing tool, the screw can protrude from the fixing surface through the insertion portion. At this time, the head of the screw hits the periphery of the insertion portion, and the insertion stops there. When the screw in this state is engaged with the tool attached to the tool attachment portion, the screw is temporarily fixed in place by the tool. Then, when the fixing tool is applied to the structure, the screw is clamped between the screwed portion of the structure and the tip of the shank of the tool, and the screw is prevented from falling out of the insertion portion. In addition, in the temporary fixation state, the tool is positioned within the through portion (long hole), so that the screw can be prevented from tilting relative to the fixing tool and coming off the tip of the tool.

[0087] (8) The fixture of the present invention is not limited to the configuration of the above embodiment. In the fixture (wiring / piping material holder) of the above embodiment, the first holding piece, the second holding piece, and the hinge are integrally formed, but they may be a combination of separate pieces. The rigid first holding piece and the second holding piece may be connected by an axial hinge, and the first holding piece and the second holding piece may rotate around the hinge.

[0088] (9) The fixture of the present invention is not limited to the configuration of the above embodiment. In the fixture (wiring / piping material holder) of the above embodiment, a locking tooth row having a large number of locking teeth is formed on the side of the first holding piece that is fixed to the structure, and a locking tooth row having a small number of locking teeth is formed on the side of the second holding piece. However, the relationship between the first locking tooth row and the second locking tooth row may be reversed, and a locking tooth row consisting of a large number of locking teeth may be formed on the inner surface of the second holding piece, and a locking tooth row consisting of a small number of locking teeth may be formed on the outer surface of the first holding piece.

[0089] (10) The fixture of the present invention is not limited to the configuration of the above embodiment. In the fixture (wiring / piping material holder) of the above embodiment, the first locking tooth row (first locking portion) has a large number of locking teeth, and the second locking tooth row (second locking portion) has three locking teeth. After all the locking teeth of the second locking tooth row engage with the locking teeth of the first locking tooth row, the locking position changes depending on the overlapping amount of the first and second holding pieces, but the locking amount (number of engagements) between the first and second locking portions is constant. However, the present invention is not limited to this. That is, in the present invention, the second locking tooth row may be configured with a large number of teeth so as to be formed over the entire overlapping portion of the second holding piece. In such a configuration, the locking amount between the first and second locking portions can increase as the overlapping amount of the first and second holding pieces increases.

[0090] (11) The wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. In the fixing device (wiring / piping material holder) of the above embodiment, the first locking portion and the second locking portion are both configured with locking teeth rows, but the present invention is not limited to this. For example, one of the first locking portion and the second locking portion may be a pin or a claw, and the other may be a hole or a groove.

[0091] (12) The wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. In the fixing device (wiring / piping material holder) of the above embodiment, the tip portion of the second holding piece is configured to overlap with the tip portion of the first holding piece from the radially outer side, but the tip portion of the second holding piece may be configured to overlap with the tip portion of the first holding piece from the radially inner side.

[0092] The present invention is not limited to the above-described embodiment and modifications, and may be implemented in various forms within the scope of the present invention. In other words, within the scope of the present invention, some of the configurations of the present embodiment may be omitted or modified, or other configurations may be added.
