There is a method of fixing the decorative panel 1 in a state of keeping a space from the structural body 4 by engaging the engaging holes 11 of the decorative panel 1 having the holes.

[Problems to be solved by the device]

However, among the above methods, the method shown in FIGS. 6 and 7 has a problem in that the nail 3 and the mounting bracket 5 are exposed on the surface, which is not preferable in terms of appearance. In the method, when the decorative panels 1 are attached, the positions of the decorative panels 1 are adjusted one by one, and the bolts 9 and the nuts 10 must be tightened in that state. Since there is a play between the engagement hole 11 and the pin 7, the decorative panel 1 is apt to rattle. Therefore, the inventors of the present invention have devised a mounting bracket 12 as shown in FIG. 10 as a mounting bracket that is not exposed on the surface, is easy to mount, and does not rattle the mounted object, and has already applied for it. (Actual application No. 1-59974 (Actual application No. 2-150338)). This mounting bracket 1
2, the outer end of the elastic side plate 13 is extended to form a holding portion 14, and the holding portion 14 can be tightened by a bolt 15 and a nut (not visible in the figure). I'm running. Therefore, by positioning the sandwiching portion 14 on the fixing portion provided on the back surface of the object to be attached, and tightening the bolt 15 and the nut in that state, the attachment fitting can be fixed to the rear surface of the object to be attached. Then, the vertical side 17 of the support 16 of the mounting bracket 12 and the spring 18 on the vertical side 17 side.
Between the engaging claw 20 of the engaging piece 19 that is pressed and urged by, for example, press-fitting a predetermined portion such as a furring strip that is arranged in a state of extending horizontally on the wall surface of the structural body. Thus, the object to be attached can be attached to the wall surface of the structural body.

However, it is necessary to make the joint width large in the process of actually using the mounting bracket 12, and this large joint width causes a problem such as deterioration of aesthetics. That is, as shown in FIG. 11, when the decorative panel 32 is attached to the wall surface of the structural body 4 by using the above-mentioned mounting bracket 12, when the decorative panel 32 is damaged, it is necessary to replace it. In that case, replace the damaged decorative panel 32 with the mounting bracket 12.
It is removed from the furring strip 36 and a new decorative panel 32 is attached. In FIG. 11, 16 is a support, and 19
Is an engaging piece, 20 is an engaging claw, 34 is an anchor bolt, 34a is its nut, 35 is a fixing metal fitting, 36 is an L-shaped furring strip, 41 is an adjusting piece, 42 is an engaging piece, and 45 and 47 are A screw rod, 46 and 48 are the nuts, and Y is a joint width of the joint 100. When the new decorative panel 32 is attached as described above, in the mounting bracket 12, the engaging claw 20 is in contact with the vertical piece 17 of the bracket 12 as shown in FIG. In order to insert and lock the dowel claw 20 into the elongated hole 38 of the furring strip 36, at least the dimension W of the drawing is used to lift the decorative panel 32, and then the panel 32 is pushed down by the dimension W as shown in FIG. Insert the engaging claw 20 into the long hole 38
Must be locked to the periphery of the. When removing the decorative panel 32, the above-mentioned dimension W must be lifted. Therefore, it is necessary to make the joint width Y larger than the above dimension W, which impairs the aesthetic appearance, and the decorative panel 32 is moved up and down when the decorative panel 32 is attached and removed. There is a problem that the amount is large.

This invention was made in view of such circumstances.
It is an object of the present invention to provide a mounting bracket by improving the mounting bracket shown in Fig. 10 that can reduce the joint width, is excellent in appearance, and can reduce the mounting work of the mounted object.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, this mounting bracket has a U-shaped cross section on both sides of a support body formed in a U-shaped cross-section and having insertion holes formed on both sides facing each other. A pair of elastic side plates, each of which is formed in a circular shape and has insertion holes formed on both sides thereof, is coaxially aligned with the insertion hole of the support body, and the U-shaped open side of the support body is formed on the support body. The elastic side plates are arranged in a state of being opposite to the U-shaped open side, and the outer ends of the elastic side plates are extended to form a sandwiching part. The bolts are inserted into the holes and the nuts are fitted to the ends of the holes to make the clamping part freely clampable, and the insertion holes are formed in the U-shaped cross section and the insertion holes are formed in the opposite side edges. Insert the strip into the U-shaped bolt of the above-mentioned support through its insertion hole, and open the U-shaped opening. Is rotatably mounted with its side facing the U-shaped vertical side of the support, and the lower end portions of the U-shaped lateral sides of this engaging piece are connected to the support via a spring body. While pressing and urging the U-shaped vertical side of the support piece, at the lower end of the U-shaped vertical side of this engagement piece, the tip end of itself engages with the lower end of the U-shaped vertical side of the support. A configuration is employed in which engaging claws that maintain a predetermined interval are provided in a protruding manner.

[Action]

That is, in this mounting bracket, the engaging piece is formed in a U-shaped cross section, and both U-shaped horizontal sides of the engaging piece are brought into contact with the U-shaped vertical side of the support member to engage the engaging claw. A gap of a predetermined distance is maintained between the tip of itself and the vertical side of the support.
Therefore, by leaving the engaging claws floating with respect to the vertical side of the support (which can also shorten the length of the engaging claws themselves), the attached object such as a decorative panel can be attached to the furring strip or the like. When mounting on the wall surface of the structural body via the, the mounting object to which this mounting bracket is fixed is lifted up a little, and the engaging claw of the mounting bracket is pressed against the furring strip to which this mounting bracket is mounted, and then the mounting target is mounted. By simply pushing the object down a little, the above-mentioned floating engaging claws are immediately separated from the vertical side of the support, and the gap between the vertical and the vertical side of the support is widened. Then, the furring strip or the like is inserted into the widened gap, guided into a space surrounded by both lateral sides of the engaging piece and the engaging claw, and prevented from coming off by the engaging claw. As described above, in this mounting bracket, the engaging claws are in a state of floating from the vertical side of the support, and since the length thereof is short, it is possible to move the mounted object slightly up and down. The mounting bracket can be engaged with the furring strip or the like. As a result, the work of attaching the object to be attached to the wall surface can be easily performed.

Next, this invention will be described in detail based on embodiments.
