DETAILED DESCRIPTION OF THE INVENTION 2 ░ The present invention relates to a mounting
device for plate-like parts. Conventionally, in a multi-way speaker system, as shown in FIGS. 1 to
3, a rectangular flange portion 3a, an arc-shaped reflecting wall 3b, and a pyramidal speaker
mounting are mounted on the baffle plate 2 of the speaker box 1 A speaker horn 3 having a part
3C is attached. Specifically, as shown in FIG. 3, the packing 4 is attached to the back surface of
the flange portion 3a, and the four corners are tightened with a screw 6. However, attaching the
Patzkin 4 with an adhesive or the like in this way is very troublesome, and there is a problem
that the working time becomes long. The present invention provides a mounting device for platelike parts which solves such conventional problems. An embodiment of the present invention will
be described below with reference to FIGS. 4 to 6. In FIGS. 4 to 6, as in FIG. 1 to FIG. 3, the parts
having the functions 5 are assigned the same reference numerals and explanations thereof will
be omitted. Screw insertion holes provided at the four corners of 7 flanges la3 of sdi'i speaker
horn 3, bosses provided around 3eid screw insertion holes 3d, 3f are provided from the outer
periphery of boss 3e toward the corners of flange portion 3a The stepped portion 6 is a patskin
formed by punching a paper or the like. In this embodiment, the ridges 3 q are provided on the
entire outer periphery of the 7 rungs 3. Then, as shown in FIG. 5 (-), the step 3f protrudes a from

the tip of the ridge 3q, and part of the patch 6 intrudes into the ridge 3q and protrudes only a
from the tip of the ridge 3q. As a result, the thickness a of the portion of the step 3f and the
portion protruding from the projection 3q of the patch 6 is configured to be substantially equal.
In addition, as shown in FIG. 5), at the four corners of the patch 6, the bosses 3e and the step 3
(the hollow portion conforming to the shape of the step 3 is provided, and the length b between
the boss 3e and the boss 3e) The length C between the hollowed out portions is configured to be
slightly longer. In the above configuration, when the PATKIN 6 is slightly bent and inserted
between the four bosses 30, the inner peripheral surface of the hollow portion of the PATKIN 6 is
lightly pressed against the outer peripheral surface of the boss 3e. As a result, the packing 6 is
temporarily fixed to the back surface of the flange portion 3a. Therefore, as shown in FIG. 6, after
the flange portion 3 & is fixed to the baffle plate 2 with the screws 5 only, the modification of the
speaker horn 3 is completed. At this time, since the tightening force of the screws 4 is
concentrated at the four corners of the flange portion 3a, without the step portion 3 (a portion
located on the outside of the boss 3e sinks toward the baffle plate 2 side The gap between the
baffle plate 2 and the vicinity of the center of the portion 3a and the four corners become
uneven, which makes the appearance unsightly.
However, in this embodiment, since the steps 3f having the same thickness as the projecting
dimension a of the patch 6 are provided at the four corners, the outer side of the boss 3e never
sinks, and the four corners are bent and the appearance becomes unsightly There is no. In
addition, in the case where the complete circular hole is not provided in the packing 6 as in this
embodiment, but the cut-out portion is provided, the following effects can also be expected. That
is, when circular holes fitted to the bosses 3e are provided at the four corners of the packing 6,
there is a situation that the circular holes can not be fitted to the bosses 3e even with slight
variations in dimension 5 accuracy. Work becomes difficult. In particular, in order to temporarily
fix PATKIN 6 with one touch only by the fitting of the round hole and the boss 3 e, the
dimensional accuracy of the round hole needs to be sufficiently high, which is extremely difficult
to realize. When the round hole is fitted to the boss 3e, the thin portion located outside the boss
3e is likely to be broken, and there is a problem that the broken portion appears to the outside
and the appearance becomes unsightly. On the other hand, if the recess 6 is provided in the pad
6 as in this embodiment and the step 31 having substantially the same thickness as the pad 6 is
provided on the outside of the boss 3e, the dimensional accuracy of the pad 6 is also obtained.
There is no need to raise the height in particular, and it is possible to temporarily fix with a single
touch without breaking a part of Patkin 6, t, 'Th? The deflection of 't, 7' y 'yy Z' 3 can be reliably
prevented Pf 'tA. -M-In addition, although the flange part of the horn was used for the speaker as
a plate-shaped component in the said Example, you may use this other plate-shaped componentarticle. Further, it is not necessary to particularly provide the six projections 3q on the outer
periphery of the flange portion 3q. As described above, according to the present invention, the
patch can be temporarily fixed to the plate-like part with one touch, and the plate-like part by the
tightening force of the screw by the action of the step provided at the four corners of the plate-
