DESCRIPTION JPS57171389
BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1 and 2 are cross-sectional views of a main part
showing a conventional protective net attachment structure, respectively, FIG. 3 is a perspective
view in which a part of a protective net and a frame according to the present invention are cut
away FIG. 4 is a cross-sectional view of a main part showing the mounting structure, and FIG. 5 is
a cross-sectional view of a main part showing the mounting structure of the holding example.
Protective net, 1a ... Peripheral part, 2 ... locking part, 3 ... speaker frame, 4 ... locking groove.
DETAILED DESCRIPTION OF THE PROBLEM The present invention relates to a sealing structure
of a protective net to be scissor-attached to a loudspeaker. 0 In the conventional sealing structure
of a protective net, as shown in FIG. 1, the peripheral portion of the protective screw top The
flange part formed on the back side of the protective net A is fixed to the speaker frame DKli via
the net presser l via the screw CK. When inserting the screw C, frank part of the protective net A
3 gauge) portion AK formed hole and the net presser BK shadow formed hole must be matched,
so that the installation work is troublesome and the number of one part and the number of steps
of screw tightening increase 0 Also, as shown in Fig. 2, the circumferential groove IK formed on
the upper surface of the outer periphery of the one speaker frame D, the peripheral portion M 'of
the protecting nut) A is forcibly inserted into the% of the rubber ring F K "), the iron-weaving net
to the speaker frame D There is a structure that fixes it or fixing work is very difficult and it is
possible to deform A and there is a drawback that there is a problem of increasing the number of
parts. 0 Therefore, the present invention solves the bottleneck as described above In addition, a
plurality of locking portions are integrally formed in the lateral direction at predetermined
intervals of the peripheral portion 'lIC 5 G of the husband's net, and the O locking portion is
fitted into the inner surface of the outer peripheral portion of the speaker frame ___ ___ 0 ___
___ 0 ___ ___ 0 ___ ___ 0 ___ ___ 0 ___ ___ 0 Explain the idea based on the embodiment of the
drawing 3B, evening 6; ->], 11. 3 is a perspective view in which a part of the protection net and
the frame according to the present invention are cut away, and FIG. 4 is a cross-sectional view of

a main part showing the same attaching structure of FIG. 4, in which 0 is a metal It is a protective
net with elastic force formed to match the opening shape of Sys- temy Power by mesh * and the
wrinkle net 1 is scoured in the downward direction to the outer periphery) and it is squatted in
the inverted dish shape Also, at the circumferential edge 1 ml 'C of the preservation net 1, a
plurality of engaging portions 2 having an S shape in the y rat are integrally Kli formed in the
side direction at predetermined intervals in the circumferential direction KG 03 is the speaker 7
Le 1, and on the inner peripheral surface 3 a of the outer peripheral portion of the wrinkle 7
REMO 3, it forms a slit-shaped locking groove 4 into which the O locking portion 2 is inserted, K
for attaching the net l to the speaker frame 3 is pressed against the locking groove 4 in a state in
which each locking portion 2 is pushed inward, Ninth, when the pushing force to the locking part
2 is released, it is locked and locked in the locking part 2 company locking groove 4 by the
outward elastic force of the protection net 1, and the protection net 1 is locked to the speaker
frame 30 In the present embodiment, although not shown in FIG. 9, + 7), the edge of the cone can
be attached to a place different from the one of the maintenance drumnet l of the speaker frame
3.
In the present embodiment, the locking groove 4 formed in the frame 3 is formed so as to
correspond to each of the plurality of locking portion snow formed in the protection net 1, If you
attach * b to tlK it will inadvertently rotate displace '' so that it regulates. Protective netting) IK
For example, when a trademark department is attached, directionality occurs in the wrinkle
conspicuous net 1 itself. Of course, only the pair of locking portions 2 and the locking grooves
40 are formed so as to correspond to each other as described above, and the locking grooves 4
into which the remaining locking portions 2 are inserted are not formed individually but
circumferentially Even so, the directionality of the preservation net 1 can be maintained 0 And in
this case, since it is only necessary to pay attention to the positional accuracy only with respect
to the pair of locking portions 2 and the locking groove 4, Easy as well as easy to handle 0
Necessary protective nets) If there is no IK directionality, it is of course that the locking serial
number may be provided integrally around the entire circumference. 3: 18 Fig. 5 is a crosssectional view of a main part of the mounting structure showing an example of Iy in the present
invention, Protective nets) IK The anchoring portion 2 forming the shadow has an upwardly
inwardly U- In addition, in the present invention, the 0 locking part 2, the edge 6 attached to the
periphery of the cone 50, the backing 7 and the gasket 8 are engaged with the locking groove 4
so that the locking 114 C) Wrapping operation on the speaker frame 3 of the wide upper / lower
groove width (0 formed in a U shape, further protected net) 1 is the same as in the above
embodiment, so it will be omitted, but one inventive dovetail building, locking Since the portion 2
is folded in a U shape, the locked state of the locking portion 2 with respect to the locking groove
4 is strengthened by both elastic forces in the outward direction and the upward and downward
direction. As described above, according to the present invention, a plurality of locking portions 2
are formed integrally in the lateral direction at predetermined intervals along the peripheral
portion 1aK of a resiliently retaining nut l and the outer peripheral portion of the speaker frame

3 The locking groove 4 for inserting and locking the locking portion 2 described above was
influenced by the inner surface 3 RL of the main body 3, so that it is possible to easily attach the
net-stay net 1 to the speaker frame 3. In addition, the number of parts can be reduced, 0 J 9 t), 7
"or protected nets) 1 and the locking part 2 can be easily formed by integral processing, resulting
in low cost 0
