When a set screw screwed into a fixing surface of a structure is fastened through an insertion hole punched at the supporting plate, both half bodies are automatically approached to cause the holder to circulate around an outer surface of the rod and hold it and further a protrusion edge formed at a lower surface corner part of the supporting plate placed at a position spaced apart from the insertion hole is press contacted with the fixing surface of the structure in a line contacted manner.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a rod fixture for attaching a rod-like member such as a cable to a structure.

  The fixture that attaches various cables, ropes and cords (hereinafter referred to as “rods”) to cars, houses, communication devices, etc. (hereinafter referred to as “structures”) is a tunnel-shaped holding part for holding or fitting rods. And a flat part are generally known, and after a rod is attached, a part that is screwed to a panel or the like of a structure through an insertion hole in the flat part is widely known. There are various types of holding parts, such as those that have a predetermined diameter in advance, a part that is partly open and rounded, and the flat part also has a lower end that extends left and right as a convex shape and is screwed in two places on both sides. The structure is such that the end of the holding part connected to the flat part is bent and overlapped on the flat part side, and a set screw is screwed into the structure from the one insertion hole that is overlapped. There are also.

  And the technique (for example, patent document 1) which made the attachment to a structure stronger than the said existing fixing tool, and was not able to rotate even if external force, such as pulling force, was added, or a holding | maintenance part A technique in which one end is extended in parallel with the flat part, a gap is provided between them, and the holding part is tightly pressed against the rod by using the elasticity of the gap when fixing with a set screw (see, for example, Patent Document 2) Etc. also exist.

JP 2009-284661 A JP 2010-517499 A

  The thing of patent document 1 provided with the detent structure is formed so that both the side fastening parts extended from the holding part holding a cable may be piled up, and it may be fixed to a material to be fixed with one screw member, Further, since the pin member is inserted and locked into the locking hole of the fixed material from the mounting hole opened in a part of the gripping portion, the effect that the rotation of the fixing tool can be prevented by the presence of the pin member. Although it is expected, it is necessary to provide a pin member separately from the screw member, which requires the manufacturing work for that purpose and the work for attaching the pin member to the fixed material. In addition to this disadvantage, the structure is complicated. Therefore, there is a problem that the cost increases accordingly.

  The technique described in Patent Document 2 relating to a cable laying clip is such that a ring made of an elastic material has a split portion into which a cable is inserted, and is attached to a structure by a plurality of fastening means. It is understood that this clip can be tightened and fixed according to the cable diameter by tightening the set screw, because the set screw in the gap is screwed into the structure. Tighten the set screw after inserting the cable into the ring, or open the split part before installing the set screw and insert the cable from there, and it is difficult to open a large gap. It can be said that the question remains whether the rod can be easily attached.

  Unlike the above-described prior art, the present invention is provided with a hinge portion having an axial center in the middle, the holding body can be arbitrarily opened and closed, and the rod can be easily attached. When the set screw is tightened to the structure, the holding body is automatically It is an object of the present invention to provide a rod fixing tool that is tightly and firmly coupled to the rod.

  The first aspect of the present invention that solves the above-mentioned problem is that a sandwiching body is formed by opposing arc-shaped halves, and both halves tilt about a hinge portion having an axial center provided on a support plate. When the clamping body is opened and closed by tightening the set screw screwed into the mounting surface of the structure through the insertion hole made in the support plate, both halves approach automatically and the clamping body circulates around the outer surface of the rod. A protruding edge formed at the lower corner of the support plate at a position apart from the insertion hole while being sandwiched is pressed against the mounting surface of the structure in a line contact manner.

  According to the second aspect of the present invention, a sandwiching body is configured by opposing arc-shaped halves, and one of the halves tilts with a hinge portion having an axis provided on a support plate as a fulcrum to open and close the sandwiching body. When the set screw screwed into the attachment surface of the structure through the insertion hole made in the support plate is tightened, the claw piece protrudingly formed on the lower half of the half body is pressed against the attachment surface and is inserted into the window hole of the support plate. So that the half is automatically close to the other half so that the holding body nips the outer surface of the rod and is formed at the bottom corner of the support plate at a position away from the insertion hole. The protruding edge is press-contacted to the mounting surface of the structure in a line contact manner.

  A spring member is attached to the axial center of the hinge portion in the first and second aspects, and both or one half is elastically biased in the opening direction.

  When the arcuate half is tilted via the hinge portion, the half halves are largely separated from each other within the tilting range, and the sandwiching body is opened, so that the rod can be easily fitted. Next, when a set screw is inserted from the insertion hole formed in the support plate, screwed into the screw hole on the mounting surface of the structure, and tightened, both halves are automatically brought close to each other with the hinge as a fulcrum and closed. Since the outer periphery of the rod is clamped by the body, the rod can be fixed quickly and reliably, and the protruding edge formed at the corner of one half is pressed into contact with the mounting surface in a line-contact manner. The rod is fixed more firmly by supporting the two points at the points.

  In this kind of fixture, most of the hinges provided with a hinge part are merely made thin with a part of the thick wall so that they can be bent easily, but the hinge part of the present invention has Since the shaft center is provided, the same function as the hinge for opening and closing the door is exhibited, and the rod can be fitted without difficulty unlike the case where the opening can be greatly opened and the gap is provided in the holding body.

It is the perspective view and parts figure which show the fixing tool in a 1st form. It is the perspective view which the support plate stood up with the hinge part as a fulcrum. It is a side view which shows the attachment process of a rod. It is sectional drawing which fixed the rod to the attachment surface of the structure. It is the perspective view and component drawing of a closed state which show the fixing tool in a 2nd form. It is sectional drawing of the state which the clamping body opened, and a rod attachment state.

  The first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the components constituting the fixture are a first part 1 and a second part 2, and a support plate 3 formed on the first part 1, A support plate 4 formed on the second part is connected via a hinge portion 5 having an axis 6. And the holding body 7 is formed on the support plates 3 and 4 by the arc-shaped halves 8 and 9 facing each other, and the ends of the halves face each other so as to be able to contact and separate. An elliptical insertion hole 10 is formed in the support plate 3, and the support plate 3 is fixed to a mounting surface 15 of a structure which will be described later. At the same time, the support plate 4 is also in close contact with the mounting surface. That is, the sandwiching body 7 is opened and closed by tilting both of the half bodies with the hinge portion 5 as a fulcrum. In the figure, reference numeral 6a denotes a spring member that constantly elastically biases the half bodies 8 and 9 in the opening direction, 11 denotes a projecting edge formed on the lower surface of the corner of the support plate 4, and 12 denotes a knurling for slip prevention formed on the inner surface of the half body 9. It is.

  The hinge portion 5 in this fixture is formed by engaging the other protruding portion 5b with the one receiving port 5a at the end of each of the support plates 3 and 4, and the shaft center 6 at the engaged central portion. The support plates 3.4 are connected to each other through the hinge portion 5.

  The support plates 3 and 4 can be rotated downward within the tilting range (approximately 90 ° or more) until they come into contact with each other via the hinge portion 5 at the connection point, so that the support plates 3 and 4 rise accordingly, and at the same time the arc-shaped half body 8.9 wide open like a hinge that opens and closes the door. In other words, when both the supports 3 and 4 are raised from the horizontal state, the half bodies 8 and 9 are opened as if the beasts are jealous as shown in FIG.

  FIG. 3 shows a process of fixing the rod 13 to the mounting surface 15 of the structure using this fixing tool. The holding body 7 is opened by opening the halves 8 and 9 with the hinge portion 5 as a fulcrum according to the outer diameter of the rod. The rod 13 is fitted inside. At this stage, the set screw 14 is still only applied to the insertion hole 10, and the support plates 3 and 4 are slightly raised from the mounting surface 15.

  When the sandwiching body 7 sufficiently sandwiches the outer periphery of the rod 13, the support plates 3 and 4 naturally move horizontally via the hinge portion 5, and both support plates are in close contact with the mounting surface 15 of the structure. Therefore, as shown in FIG. 4, when the set screw 14 inserted through the insertion hole 10 formed in the support plate 3 is screwed into the screw hole 16 formed in the attachment surface 15, the support plate 3 is press-fixed to the attachment surface 15 and the other support is supported. Since the plate 4 is also closely fixed, both the support plates 3 and 4 are coupled to the mounting surface 15 in a balanced manner.

  The support plates 3 and 4 are opened up to 180 ° through the hinge portion 5, and the positions of the support plates 3 and 4 are held immovable since they act as stoppers. That is, when the set screw 14 inserted from the insertion hole 10 of the support plate 3 in the horizontal state is screwed into the mounting surface 15 and tightened, the other support plate 4 is also automatically brought into close contact with the mounting surface 15 and the state does not shake. Thus, even if an external pressure is applied to the rod 13, the mounting state is not hindered.

  If the protruding edge 11 is formed at the corner of the support plate 4, the protruding edge 11 comes into line contact with the mounting surface 15, and can be attached to the structure by two-point support on the left and right together with the set screw 14. it can. Due to the presence of the protruding edge 11, the hinge portion 5 side is surely lifted up, and a slight gap 17 is formed between the support plate 4 and the mounting surface 15. Even after the set screw 14 is tightened to the mounting surface 15, the cushion effect is exhibited by this gap 17. Even when an external force is applied to the rod 13, the function as a fixture for supporting the rod 13 is maintained for a long time because the load is absorbed by the cushion function. Even if the mounting surface 15 is round or has a slight inclination angle, the protruding edge 11 directly plays a role of fine adjustment.

  FIG. 5 shows the second embodiment of the present invention, and the components constituting the fixture are the first component 1 and the second component 2, and the support plate 3 on the first component 1 side and the second component 2 side. A hinge portion 5 having an axis 6 is provided in the middle of the support plate 4. The support plate 3 and the support plate 4 are integrally formed via a hinge portion 5, and a sandwiching body 7 is formed on the support plates 3 and 4 by opposed arc-shaped halves 8 and 9. Although they face each other so as to be able to contact and separate, in this second form, only the half 8 on the support plate 3 tilts with the hinge portion 5 as a fulcrum, and the half 9 on the support plate 4 It is integrally formed with the support plate and does not tilt.

  When the support plate 3 is provided with an elliptical insertion hole 10 and the support plate 3 is fixed to a mounting surface 15 of a structure to be described later, the integrally formed support plate 4 naturally comes into close contact with the mounting surface. . That is, the holding body 7 is opened and closed by tilting one half 8 with the hinge portion 5 as a fulcrum. At the lower end of the half body 8 that tilts, there is a claw piece 8a that appears and disappears in the window hole W formed in the middle of the support plates 3 and 4, and when the half bodies 8 and 9 are close to each other, the claw piece Is immersed in the window hole W (see FIG. 5A), and protrudes from the window hole W when separated (see FIG. 5B). In the figure, 6a is a spring member that constantly elastically biases the half body 8 in the opening direction, 11 is a protruding edge formed on the lower surface of the corner of the support plate 4, and 12 is a knurling for slip prevention formed on the inner surface of the half body 9. is there.

  FIG. 6 is a view showing a state in which the sandwiching body 7 is opened and a state in which the rod is fixed. Before tightening the set screw 14, the half body 8 is opened with the hinge 5 as a fulcrum and the rod is inserted into the sandwiching body 7. 13 is fitted. At this stage, the set screw 14 is still only applied to the insertion hole 10, and the support plates 3 and 4 are lifted because the claw piece 8 a at the lower end of the half body protrudes from the window hole W, and is slightly lifted with respect to the mounting surface 15. It is in the state.

  When the clamping body 7 clamps the outer periphery of the rod 13, the half body 4 tilts around the hinge portion 5 and the claw piece 8 a at the lower half of the half body enters the window hole W, so that there is no obstacle and the support plate 3 4 is in a horizontal state with respect to the mounting surface, and both support plates are in close contact with the mounting surface 15 of the structure. Then, when the set screw 14 inserted through the insertion hole 10 formed in the support plate 3 is screwed into the screw hole 16 formed in the attachment surface 15, the support plate 3 is pressed and fixed to the attachment surface 15, and the other support plate 4 is also closely fixed. Therefore, both support plates 3 and 4 are coupled to the mounting surface 15 in a well-balanced manner. In this case as well, the protrusion 11 on the lower surface of the support plate 4 is directly on the mounting surface 15, so that a gap 17 is generated between the support plates 3 and 4 and the mounting surface 15 and the cushion effect can be exerted, as in the first mode. .

  As described above, even in the first form and the second form, both or one of the halves 8 and 9 on the support plates 3 and 4 tilt with the hinge portion 5 as a fulcrum so that the halves of each other The holding body 7 can be opened and closed automatically by making contact and separation, and the operation is completed by a simple operation of fitting the rod 13 into the holding body 7 and tightening one set screw 14 to the mounting surface 15. Good workability.

  In this fixing tool, the holding body 7 can be arbitrarily sized according to the diameter of the rod 13, and the material, thickness, etc. can be determined according to the application, the presence or absence of the spring member 6a, etc. Changes within the scope of the object and effects of the present invention also belong to the category of implementation of the present invention.
