JPS5915110Y2 - Mounting structure for flexible plate-like objects - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a mounting structure that allows flexible plate-like objects such as panels and filters to be detachably and easily attached to audio equipment and other various articles. be.

For example, in a box speaker, the front surface of a box speaker is covered with a sound-permeable cloth or the like so that the cone speaker or the like inside is not visible.

However, in the past, when assembling the box speaker, the work of attaching cloth to the front surface of the box speaker was inefficient because a mounting frame covered with cloth was secured with screws.

Further, similar problems have occurred with filters and the like in various products, and the efficiency of the installation work has been poor.

The present invention has been developed in view of these points, and provides a structure for attaching a flexible plate-like object to an opening of an object to be attached, which makes it easy to attach the flexible plate-like object and reduces manufacturing costs. It is something to do.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be explained about an Example based on drawing.

1 is a box speaker, which is made up of a speaker case 2 and a front panel 7 attached thereto.

A rectangular sound emitting opening 3 is formed in the front of the speaker case 2, and treble and bass cone speakers 5a, 5b, and 5C attached to a baffle plate 4 are housed in three upper and lower stages inside the opening. has been done.

Further, the speaker case 2 is provided with an engagement groove 6 on the inner circumferential surface of the opening 3 at approximately the center of each side.

On the other hand, the front panel 7 that covers the opening 3 is made of a flexible material such as synthetic resin, and is formed into a rectangular shape having an outer shape that matches the opening 3. A retaining lug 8 is integrally provided in a protruding manner corresponding to the mating groove 6.

In the front panel 7, a large number of sound guide holes 10 are bored in the inner sound transmitting part 9, and a stretchable net 11 such as jersey is attached to the front surface of the sound transmitting part 9, and the corners of the sound transmitting part 9 are fixed. A notch groove 12 extending toward approximately the center of the front panel 7 is formed at the edge.

As a result, the retaining lug piece 8 is positioned between the notch grooves 12.

Therefore, when attaching the front panel 7 to the sound emitting opening 3 of the speaker case 2, if the front panel 7 is pressed inward with the front panel 7 substantially aligned with the opening 3, the front panel 7 will be deformed, especially if the notch groove 12 Each side in between is curved, and when pressed further, the retaining tabs 8 engage with the retaining grooves 6, and the front panel 7 is attached.

Although this embodiment has been described with respect to the speaker 1, it goes without saying that the present invention can also be applied to flexible plate-like objects such as front panels of various types of audio equipment, filters of various articles, and paneling boards.

Further, although the cutout grooves 12 are provided at the corner edges of the front panel 7, they may be provided close to both sides of the retaining tabs 8.

As described above, according to the present invention, since the flexible plate-like object has an outer shape that matches the opening of the object to be attached, there is no risk of dust etc. entering the inside, and the retaining groove is formed in the object to be attached. On the other hand, since the retaining lug and the notch groove are provided on the flexible plate-like object, the retaining lug can be engaged with the engaging groove simply by pressing the plate-like object. The work of attaching a plate-like object to an attachment can be easily and efficiently performed, parts such as fittings are no longer required, and production costs and manufacturing costs can be reduced.

In addition, plate-like objects can be easily removed, and maintenance and
Replacement work can be done easily.

Furthermore, by positioning the retaining lug between the notch grooves, the adjacent parts of the retaining lug can be bent extremely easily, making it easier and more efficient to attach the plate-like object to the object to be attached. can do well.
