The present invention relates to a material fixture.

  Conventionally, as this type of wiring / pipe material fixing tool, one in which the wiring / pipe material is clamped by a pair of elastic clamping plates such as saddles and fixed to a support material such as a hanger rail is known. Examples of fixtures related to this include those described in Japanese Utility Model Publication No. 3-46084, Japanese Patent Laid-Open No. 2001-50427, and the like.

FIG. 10 shows a conventional wiring / piping material fixture. In the figure, the fixture 71 is provided with a notch locking portion 73 at the lower end portion of a pair of elastic clamping plates 72, 72 that clamp the electric conduit 51 as a wiring / piping material, and a bolt 74 is attached to the upper end portion. A flange 75 is formed. On the other hand, the support member 41 to which the fixing tool 71 is attached is made of a steel material having a substantially U-shaped cross section, and a pair of bent pieces 45, 45 are provided obliquely downward on the inner side from the opening side end portion 44. In order to fix the fixing tool 71 to the support member 41, the lower end portion of each elastic clamping plate 72 is inserted into the support member 41 from the opening 46 side, and then the elastic clamping plate 72 is rotated 90 degrees to lower the lower end portion. The conduit 51 is held from both sides while the notch locking portion 73 is locked to the pair of bent pieces 45, 45 of the support member 41. Then, the bolts 74 are inserted into the upper end flange 75 and tightened to connect the pair of flanges 75 to clamp and fix the conduit 51.

  However, in order to fix the conduit 51 to the support member 41 using the conventional fixture 71 described in the above publication, etc., the pair of elastic clamping plates 72, 72 are temporarily fixed to the longitudinal direction of the support member 41. Are inserted through the openings 46 of the support member 41, and then the respective elastic clamping plates 72 are rotated by 90 degrees to change the direction so as to be orthogonal to the bent piece 45 of the support member 41 and at the lower end. The conduit 51 is held from both sides while the notch locking portion 73 is locked to the bent piece 45. Next, the bolts 74 were inserted into the flanges 75 at the upper end portions of the pair of elastic clamping plates 72, 72, and tightened using a tool to firmly clamp the conduit 51. Therefore, many operations are required, and it takes a lot of time and labor to install the fixture 71 on the support member 41 and fix the conduit 51.

  Further, the fixing member 71 is such that a notch locking portion 73 formed at the lower end portion of the elastic clamping plate 72 is locked in a direction orthogonal to the bent piece 45 of the support material 41. Although the removal from the opening 46 can be prevented, it was easily displaced in the longitudinal direction with respect to the support material even after being fixed to the support material 41. That is, by tightening the bolt 74 and clamping the conduit 51, a sliding resistance is generated between the notch locking portion 73 of the elastic clamping plate 72 and the bent piece 45 of the support member 41, and a certain degree of deviation is prevented. Although it is possible, since the elastic clamping plate 72 of the fixture 71 is formed of a steel plate or the like, after being fixed to the support member 41, an external force is directly applied to the fixture 71, or an external force such as tension or bending is applied to the conduit 51. By acting, the fixture 71 was easily displaced in the longitudinal direction. As a result, the arrangement of the conduits 51 fluctuates and comes into contact with other wiring / piping materials, or an unreasonable force is applied to the conduits 51 itself, wiring devices, connection points with piping devices, etc. Cracks may occur or poor connection may occur.

  Furthermore, the fixture 71 is composed of two members, ie, a pair of elastic clamping plates 72 and 72 for clamping the conduit 51, or three members if bolts 74 are added, so that the parts management is difficult and the manufacturing is difficult. The cost was also bulky.

  Therefore, the present invention can be easily fixed to the support material and is not displaced with respect to the support material, so that the wiring / pipe material can be easily and stably fixed along the ceiling surface of the building. Thus, it is an object to provide a wiring / pipe material fixing tool that can be wired and piped and that is easy to manage components and inexpensive.

  The wiring / pipe material fixing tool according to claim 1 is for fixing the wiring / pipe material to a support material, and a contact portion that contacts a base portion having a rotation center and an opening side end portion of the support material. And an engagement portion that is provided on one side of the base and engages with a pair of bent pieces of the support member, and extends to the other side of the base, and grips the wiring / pipe material from both sides. And a grip portion. The engaging portion includes an elastic piece that can be elastically deformed in the width direction of the support member, and an engaging claw that is provided on the elastic piece and sandwiches the bent piece of the support material with the contact portion. ing. The engaging claw is inserted from the opening of the support material and engaged with the bent piece, and one side of the base portion is expanded with the rotation center as an axis. It is formed so as to rotate in the longitudinal direction and press-contact with the bent piece.

  Here, the support member is formed in a U-shaped cross section with a bottom plate and a pair of left and right side plates, and includes a bent piece that bends inwardly at an opening side end portion of each side plate. Can include a hanger rail. The support material opens upward when laid along the double ceiling surface of the building, and opens sideways when laid along the wall surface. A pair of bent pieces of the support material are formed on both sides of the opening, and after being bent at right angles inward from each opening side end portion, the bent pieces are further bent to the bottom plate side, or each opening side It is formed in a form such as being bent obliquely downward from the end toward the inside. The bent piece may be simply bent at a right angle from each opening side end toward the inside.

The rotation center is formed in the base at a direction that coincides with the width direction of the support member, and is generally provided at the center of the base. The rotation center can be formed as a thin hinge, for example.
The abutting portion is generally provided at the base portion, but may be provided at another location, and abuts on the opening side end portion of the support member from the direction orthogonal to the opening surface.
A pair of the engaging portions are provided on the one side of the base in the width direction of the support material after fixing so as to engage with the pair of bent pieces of the support material, and usually the length of the support material after fixing. A pair is provided symmetrically about the center of rotation in the direction. That is, a total of four engaging portions are usually provided, but a pair may be provided only in the width direction of the support member after being fixed. Depending on the mounting direction of the fixture with respect to the support material, for example, when the support material is laid along the ceiling surface, one side of the base portion is below the base portion, and the support material is on the wall surface. When laid, one side of the base is on the left or right side with respect to the base. The engaging portion engages with the bent piece from the inside of the support member. The elastic piece of the engaging portion bends in the width direction of the supporting member with the base portion as an axis, and the engaging claw of the engaging portion engages with the distal end portion of the bent piece of the supporting member.
The grip portion is provided on the side opposite to the engaging portion with respect to the base portion.

  When the engaging claw is engaged with the bent piece of the support material and the one side of the base part, that is, the engaging part side is expanded to the left and right with the rotation center as an axis, The shaft is rotated in the longitudinal direction of the support member so as to be in pressure contact with the bent piece. Accordingly, the engaging portion is bent in the width direction with respect to the support material and the engaging claw is engaged with the bent piece, whereas when the base portion is expanded, the engaging claw is in the longitudinal direction of the supporting material. And the bending direction of the elastic piece is 90 degrees different from the rotation direction of the engaging claw. As described above, when a pair of engaging portions provided on one side of the base portion are formed symmetrically about the rotation center as an axis, when the base portion is expanded, each of the engaging portions is mutually in the longitudinal direction of the support material. It will rotate to the opposite side and will press-contact with the bending piece of this support material. The expansion of one side of the base can be performed, for example, by tightening the gripping part as described in claim 2, and one of the elastic pieces of the engaging part as described in claim 3. This can be done by fastening a screw to the end face on the side.

  Thereby, the fixing tool is simply inserted into the opening of the support member, and the elastic piece of the engaging portion is inserted while being bent in the width direction of the support member, and the engaging claw is engaged with the tip end portion of the bent piece, The bent piece is sandwiched by the abutment portion and attached to the support member, and the removal from the support member is prevented. Further, the wiring / pipe material is clamped by the gripping part and held by the fixture. Then, by expanding one side of the base portion in the longitudinal direction of the support material with the rotation center as an axis, the engagement claw rotates in the longitudinal direction of the support material, presses against the tip of the bent piece, and brakes Functions as a means. Therefore, the fixture is fixed to the support member with a single touch, and is reliably prevented from shifting in the longitudinal direction with respect to the support material.

Furthermore, in the wiring / piping material fixture according to claim 1 , the gripping portion is tightened in a direction orthogonal to the elastic deformation direction of the elastic piece of the engaging portion to grip the wiring / piping material, and the gripping portion is tightened. As a result, one side of the base expands around the center of rotation. As a result, the gripping portion is clamped in the elastic deformation direction of the elastic piece of the engaging portion, that is, in the direction orthogonal to the width direction of the support material, that is, in the longitudinal direction of the support material. One side of the support member expands in the longitudinal direction of the support member around the rotation center.

In the wiring / piping material fixture according to the second aspect of the present invention, in particular, one side of the base portion is expanded around the rotation center by tightening a screw to one end face of the elastic piece of the engaging portion. That is, when the screw is tightened, the screw is pressed to the side while screwing the end face on one side of the elastic piece of the engaging portion, so that one side of the base portion is expanded with the rotation center as an axis. Here, when a pair of engaging portions are provided symmetrically with respect to the rotation center, it is easy to insert and tighten a screw between the pair of elastic pieces. In addition, the means for expanding one side of the base by tightening the gripping part of claim 2 may be further added with means for expanding by tightening the screw of this claim.

The wiring / piping material fixture according to a third aspect of the present invention further includes a torsion prevention plate that abuts against opposite ends of the pair of bent pieces of the support member to prevent twisting. The fixing tool may be subjected to a twisting force in a direction along the opening surface of the support material when the wiring / pipe material is pulled. Here, since the engaging part of the fixing tool elastically bends in the direction perpendicular to the plane thereof, that is, the width direction of the support member, the elastic piece becomes a bent piece of the support member when a twisting force is applied to the fixing member. Allows the fixture to be twisted by bending inwardly, and the fixture may be twisted and deformed as it is. However, in the present claim, since the twist prevention plate is provided, even if a twisting force is applied, the twist prevention plate abuts against the end of the bent piece of the support material and prevents the fixture from being twisted. .

The wiring / pipe material fixing tool according to claim 4 , in particular, includes a pair of gripping pieces with which the gripping portion is engaged with each other, and the gripping pieces are connected to each other to accommodate a plurality of sizes of wiring / piping materials.

At the same time, the conduit 51 is firmly held by the pair of gripping pieces and is stably fixed to a predetermined position of the support member 41.

  The gripping piece 23 and the gripping piece 24 can be manually tightened, but as shown in FIG. 6, the gripping protrusion 25c and the gripping protrusion 27a are gripped using a gripping tool 61 such as pliers or pliers. In this case, it can be tightened more firmly. In addition, after first tightening by manual operation, it can be tightened by gripping both gripping protrusions with the gripping tool 61.

Next, a method of changing the fixing position with respect to the support member 41 by shifting the fixture 1 after fixing the conduit 51 to the support member 41 via the fixture 1 will be described.
First, once the conduit 51 is gripped by the gripping portion 21, the upper protruding piece 25 and the lower protruding piece 28 are engaged with each other and cannot be rotated as they are, as shown in FIG. Insert the tip of a tool such as a flat-blade screwdriver into the insertion groove 29 between the upper protruding piece 25 and the lower protruding piece 28, and turn the tool while prying both protruding pieces to lock the locking teeth of both protruding pieces. It releases and expands right and left, separating both protrusion pieces up and down.

  Accordingly, when the pair of engaging portions 11 and 11 are fixed, as shown in FIG. 5, the bent piece 45 of the support member 41 is supported at the opposite end 17 of the engaging surface 14 of the engaging claw 13. From the state in which the lower end 47 is firmly in pressure contact, the hinge 5 is rotated in a direction close to each other about the shaft, and as shown in FIG. The lower end 47 of the bent piece 45 is in a substantially parallel state.

  Next, as shown in FIG. 7 (b), when the gripping pieces of the gripping part 21 are gripped and the distance between them is further expanded to the left and right, the opposing ends of the pair of engaging parts 11 and 11 are mutually opposite. It will be in the state of almost contacting. Here, in this state, the engagement claw 13 has a rotation center side end portion 15 opposite to the counter-opposing side end portion 17 as shown by the two-dot chain engagement surface 14 in FIG. However, since the pressing member 1 is again pressed against the lower end 47 of the bent piece 45 of the support member 41, it is difficult or impossible to move the fixing tool 1, and the fixing tool 1 cannot be displaced.

  However, the engaging portion 11 of the present embodiment is formed on the inclined surface 16 inclined downward so that the rotation center side end portion 15 of the engaging surface 14 of the engaging claw 13 is separated from the hinge 5. For this reason, the space | interval of the hinge 5 and the rotation center side edge part 15 of the engaging surface 14 is large. Thereby, the space | interval of the contact part 6 and the engaging surface 14 of the engaging part 11 expands from the dimension a of FIG. 7 (a) to the dimension b of the same (b). Here, a <b. As a result, the pressure contact of the rotation center side end 15 of the engaging claw 13 with respect to the bent piece 45 of the support member 41 is completely released, and the fixture 1 can easily move in the longitudinal direction along the support member 41. It becomes. Therefore, the fixing tool 1 is shifted to a predetermined position, or the fixing tool 1 is once removed and changed to another position.

  In addition, the press contact of the rotation center side end portion 15 of the engaging claw 13 with respect to the bent piece 45 of the support member 41 grips both the gripping pieces of the gripping portion 21 and further widens the interval as described above. However, it can also be performed by pushing down the connecting portion 32 and the connecting portion 33 that protrude in the horizontal direction from the two anti-twist plates 31. That is, when the left and right connecting portions 32 and 33 are pushed down, the pair of engaging portions 11 and 11 are rotated about the hinge 5 via the torsion prevention plate 31 and the base portion 2, and the opposing end portions are mutually connected. However, as shown in FIG. 7 (b), the contact surface is substantially in contact with the lower end 47 of the bent piece 45 of the support member 41, and the pressure contact of the engagement surface 14 of the engagement claw 13 is released. As a result, the fixture 1 can be easily moved in the longitudinal direction along the support member 41. In this case, when the pressure contact is released, the entire fixing device 1 can be pushed forward along the bent piece 45 of the support member 41 and moved in the longitudinal direction while pushing down the connecting portion 32 and the connecting portion 33. The fixture 1 can be easily shifted.

  Next, after fixing the conduit 51 to the support member 41 via the fixture 1, the conduit 51 can be removed by the same operation as the method for changing the fixing position of the fixture 1 described above. That is, the tip of a tool such as a flathead screwdriver is inserted into one of the insertion grooves 29 formed on both sides between the upper protruding piece 25 and the lower protruding piece 28 shown in FIG. The projecting piece 25 and the lower projecting piece 28 are expanded and separated in the vertical direction while prying them at the tip of the tool. Next, in this state, the gripping piece 23 and the gripping piece 24 are expanded in a direction away from each other, and the conduit 51 is removed. As the grip portion 21 is expanded, the pair of left and right engaging portions 11 and 11 rotate in a direction approaching each other about the hinge 5, so that the engaging surface 14 is a bent piece 45 of the support member 41. The pressure contact with the lower end 47 is released.

Next, a plurality of fixtures 1 can be connected to each other and fixed to the support member 41.
FIG. 8 shows a structure in which two fixtures 1 are juxtaposed and fixed to a support material 41. In FIG. 8, the two fixtures 1 include a fitting claw 32 a of the connecting portion 32 provided at the lower portion of the twist prevention plate 31 of one fixture 1 and a lower portion of the twist prevention plate 31 of the other fixture 1. They can be connected to each other simply by fitting the fitting claws 33a of the connecting portion 33 provided on the connecting portion 33. As a procedure, after fixing one of the fixing tools 1 to the support member 41, the other fixing tool 1 may be fixed and connected. You may fix to the support material 41 simultaneously. Thereby, the fixture 1 mutually reinforces, can prevent more reliably shifting to the longitudinal direction of the support material 41, and can hold | maintain the conduit 51 stably in a fixed alignment state.

Next, the operation of the fixture 1 of this embodiment will be described.
First, the engaging portion 11 of the fixture 1 includes an elastic piece 12 that can be elastically deformed in the width direction of the support material 41, and an engagement claw 13 that holds the bent piece 45 of the support material 41 with the contact portion 6. Therefore, the fixing tool 1 simply inserts the engaging portion 11 into the opening 46 of the support member 41 and pushes it in while the elastic piece 12 of the engaging portion 11 is bent in the width direction of the support member 41. The engaging claw 13 is inserted and engaged with the lower end 47 of the bent piece 45, and is attached to the support member 41 with the bent portion 45 sandwiched by the abutment portion 6 and is prevented from being detached from the support member 41. The

  Next, in a state where the engaging claw 13 is engaged with the bent piece 45 of the support member 41 as described above, when the grip portion 21 is tightened to grip the conduit 51, the pair of engaging portions 11, 11 are The engaging claw 13 rotates in the longitudinal direction of the support member 41, that is, rotates in a direction different from the deflection direction of the elastic piece 12 by 90 degrees. Press contact. As a result, the conduit 51 is stably gripped by the fixture 1 by the grip portion 21, and at the same time, the fixture 1 is brought into contact with the support member 41 by the press contact with the lower end 47 of the bent piece 45 of the engagement claw 13. On the other hand, it is reliably prevented from shifting in the longitudinal direction. As a result, the conduit 51 can be wired and piped easily and stably at a certain position along the ceiling surface of the building.

  Furthermore, since the fixture 1 includes the engaging portion 11 that engages with the bent piece 45 of the support member 41 and the grip portion 21 that grips the conduit 51, the parts can be easily managed as a single unit and inexpensively. Can be manufactured.

  Since the twist preventing plate 31 is provided, even if a twisting force is applied by pulling the conduit 51, the twist preventing plate 31 contacts the end of the bent piece 45 of the support member 41. The fixing device 1 is prevented from being twisted and deformed.

  By the way, in the said embodiment, although the engaging part 11 is rotated centering on the hinge 5 by tightening the holding part 21, it expands to right and left, but other means, for example, FIG. As shown in FIG. 9, the screw 62 can be expanded by tightening.

  As described above, the end surface 12 a on one side of the elastic piece 12 of the engaging portion 11 is formed in an arcuate concave surface, and its radius of curvature is slightly smaller than the radius of the male screw of the screw 62. Therefore, as shown in FIG. 9A, the screw 62 is attached to the screw hole 3 b of the recessed groove portion 3 of the base portion 2. In this state, the engagement surface 14 of the engagement claw 13 is merely in contact with the lower end 47 of the bent piece 45 of the support member 41. Next, as shown in (b), when the screw 62 is further tightened, the screw 62 is pressed to the side while screwing the end face 12a on one side of the elastic piece 12 of the engaging portion 11, and a pair of elastic pieces is obtained. Push 12 to the left and right. At this time, the entire head portion of the screw 62 is accommodated in the recessed groove portion 3 of the base portion 2, and a part of the head portion of the screw 62 is prevented from projecting upward from the opening of the recessed groove portion 3 to interfere with the conduit 51. The As a result, the pair of engaging portions 11 and 11 are rotated in the expanding direction around the hinge 5 without the gripping portion 21 being tightened, and the engaging surface 14 of the engaging claw 13 is folded on the support material 41. The lower end 47 of the bent piece 45 can be pressed.

  However, in order to expand the pair of engaging portions 11, 11 to the left and right, the expanding means by tightening the gripping portion 21 is basically used, and the expanding means of the engaging portion 11 by the screw 62 is tightening of the gripping portion 21. It may be used as a tightening means after the expansion due to.

By the way, in the said embodiment, although the contact part 6 which clamps the conduit 51 with the engaging claw 13 is provided in the lower surface of the bottom part 3a of the groove part 3 of the base 2, you may provide in another location.
Moreover, although the hinge 5 is provided in the lower surface center of the bottom part 3a of the ditch | groove 3 of the base 2, you may provide in another location similarly. The hinge 5 is formed by thinning a part of the bottom 3a, but is not limited thereto.

  Further, the engaging surface 14 of the engaging claw 13 of the engaging portion 11 has the rotation center side end portion 15 formed on the inclined surface 16, but the entire engaging surface 14 is formed on the inclined surface 16. Also good. In this case, the engagement surface 14 of the engagement claw 13 can be pressed against the bent piece 45 of the support member 41 even if the amount of rotation of the engagement claw 13 about the hinge 5 is small.

  Moreover, although the engaging part 11 is provided with a total of four each on the front side and the rear side of the fixture 1, it is not limited to this, and the left and right sides are respectively provided on the front side and the rear side of the fixture 1. You may provide only in any one side. That is, a total of two engaging portions 11 may be formed at opposite positions or diagonal positions. Alternatively, three or more may be formed on the front surface side and the rear surface side of the fixture 1, respectively.
