- the moving groove 34 may be formed to facilitate movement along the
- the moving groove 34 is formed corresponding to the longitudinal frame portion of the mounting frame 2, that is, formed between the elastic blades 32. ing.
- the reinforcing elastic member 4 is formed in a substantially cylindrical shape by an elastic material such as a high elastic polymer material such as rubber.
- the reinforcing elastic member 4 is inserted into the mounting frame 2 from the opening 22 and abuts on the rear end pinching surface 23 of the mounting frame 2. Further, as shown in FIGS. 14 and 15, on the outer peripheral surface of the reinforcing elastic member 4, when it is inserted into the mounting frame 2, the streaks at the positions corresponding to the frame portion in the longitudinal direction and the slits 21. The concave and convex surface is formed. Then, the projection 41 can be fitted into each slit 21 so that the projection 41 can be fitted.
- a screw through hole 42 for inserting the mounting screw 5 is formed on the axis of the reinforcing elastic member 4. Therefore, in the fixing fixture la according to the first embodiment, the reinforcing elastic member 4 is fitted into the rear end side of the mounting frame 2 and then the locking member 3 is fitted into the front end side.
- the screw hole 2 of 2, the screw hole 42 of the reinforcing elastic member 4, and the screw hole 33 of the locking member 3 are formed substantially in a straight line.
- a pilot hole hi is drilled in the fastening object X.
- the diameter of this pilot hole hi may be formed equal to or slightly larger than the outer diameter of the mounting frame 2.
- a screw hole h2 for inserting the mounting screw 5 and a tapered portion t to be engaged with the head of the mounting screw 5 are formed.
- the elastic blade 32 of the locking member 3 is accommodated in the slit 21 of the attachment frame 2 according to the insertion operation. At this time, there is a possibility that a frictional resistance may be generated between the elastic blade 32 and the pilot hole hi and there is a possibility of being caught. Because the reinforcing elastic member 4 is interposed between the elastic blade 32 and the rear end pinching surface 23. The locking member 3 is moved forward according to the operation of pushing the mounting frame 2 and passes without stopping in the pilot hole hi. Then, when the elastic blade 32 completely passes through the lower hole hi, as shown in FIG. 17, the elastic blade 32 restores due to its elastic force and radially expands from each slit 21.
- the fixing attachment la when the fixing attachment la is inserted into the lower hole hi, the flange portion 25 of the attachment frame 2 abuts against the fastening object X to determine the insertion end position, and the fixing attachment la is inserted into the lower hole hi Fall inside I have nothing to do.
- the mounting screw 5 is inserted.
- the inserted mounting screw 5 passes through the screw insertion hole 24 of the mounting frame 2 and the threaded through hole 42 of the reinforcing elastic member 4 and then reaches the threaded hole 33 of the locking member 3.
- the mounting screw 5 is rotated, it is screwed into the female screw 33a of the locking member 3 to draw the locking member 3 toward the front side (FIG. 18).
- the rotational torque of the mounting screw 5 causes the mounting frame 2 to receive a rotational force in the circumferential direction via the locking member 3.
- the projection piece 26 bites into the inner wall surface of the pilot hole hi, thereby preventing rotation. To prevent. Further, when the tightening becomes strong and the rotational force in the circumferential direction becomes large, the reinforcing elastic member 4 is pressed by the elastic blade 32 to be elastically deformed as described later, and is expanded outward to be the pilot hole hi and this hole Since it abuts on the periphery, corotation can be prevented.
- the elastic blade 32 When the set screw 5 is further tightened, as shown in FIG. 19, the elastic blade 32 abuts on the inner wall of the object X to be further expanded. As the elastic blade 32 moves to the rear side, the reinforcing elastic member 4 also slides the protrusion 41 along the slit 21 and moves to the rear side. Thereby, the reinforcing elastic member 4 is contracted in the longitudinal direction and expanded in the radial direction. The head of the mounting screw 5 is locked to the tapered portion t of the object Y to be fastened. As described above, the fastening object X and the fastening object Y are pinched and fastened by the head of the mounting screw 5 and the elastic blade 32 of the reinforcing elastic member 4 and the locking member 3.
- the reinforcing elastic member 4 is elastically deformed to be interposed between the elastic blade 32 and the fastening object X, and abut on the peripheral portion of the pilot hole hi to contact the tip of the elastic blade 32.
- the elastic blade 32 can prevent the fastener X from being broken.
- strong fastening is possible to wall materials etc. of brittle nature such as gypsum board
- the feature of the fixing fixture lb in the second embodiment is that the fixing elastic member 6 is used instead of the reinforcing elastic member 4 without using the mounting frame 2 in order to reduce the number of parts. .
- the fixing elastic member 6 has a force substantially equal to that of the reinforcing elastic member 4, and as shown in FIGS. 21 and 24, the ridge portion 41 is not formed on the outer peripheral surface of the cylindrical main body.
- the flange portion 61 is formed at the rear end.
- the front end portion of the fixing elastic member 6 is a rear end of the locking head 31 and is fixed to the base of the elastic blade 32 by an adhesive or the like.
- the outer diameter of the fixing elastic member 6 may be arbitrarily set as long as it is inserted into the pilot hole hi, but for example, if it is formed in a size substantially equal to the pilot hole hi, the clearance from the pilot hole h1 It is easy to block and to prevent corotation.
- the flange portion 61 abuts on the fastening object X, the flange portion 61 does not fall off accidentally.
- the locking member 3 passes through the lower hole hi, the elastic blade 32 is expanded. Thereafter, the locking member 3 is pulled toward the near side by screwing in the mounting screw 5. Then, as in the first embodiment, the object Y to be fastened is fixed to the object X by being held between the head of the mounting screw 5 and the elastic blade 32 and the elastic member 6 for fixation.
- the fixed attachment 1B according to the present invention can be configured with a smaller number of parts.
- the adhesion can be further enhanced because the lower end of the mounting frame 2 can be in contact with the lower hole hi or the peripheral portion without passing through the slit 21 of the mounting frame 2.
- the to-be-fastened object Y was fixed to the fastening object X by the fixing fixture la of the first embodiment, and the tensile strength test was performed. Test pieces in this tensile strength test Five of them were prepared, and their average value was calculated.
- the fastening material X uses a plaster board, and the plaster board is drilled with a 11. Omm diameter pilot hole hi. In addition, I used the 5. Omm diameter mounting screw 5 for fastening.
- a fixing fixture not provided with the reinforcing elastic member 4 was prepared, and the tensile strength was similarly measured.
