Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a decorative frame to a full plate of a speaker box.

Recently, as one type of mounting device, one of a male member and a female member is fixed to the butt-full plate and decorative frame of a speaker box, and at least one of them is made of an elastic material, and the outer periphery of the male member is It has been proposed to form a large number of uneven lines on the surface or the inner peripheral surface of the female member so that the two members fit together (for example, Japanese Patent Publication No. 55-2797).

According to this mounting device, since the above-mentioned uneven stripes are shaped in the axial direction, the air inside the female member is discharged through the uneven strips when fitting both members, and the fitting is easy. It is equipped with

However, since the uneven stripes are formed in the axial direction, that is, in the direction in which the male member is pushed in, there is a problem in that they tend to come off easily.

The present invention solves the above-mentioned drawbacks, allows the male and female members to fit together properly without obstructing the internal air evacuation function.
To provide a device for attaching a decorative frame to a speaker box without fear of loosening or coming off unnecessarily.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 indicates a male member, and 2 indicates a female member, one of which is fixed to a double plate and a decorative frame (not shown), respectively.

In the illustrated example, pleats 2a are formed and attached to the outer circumferential surface of the female member 2, and the pleats 2a are driven into the holes for drying.

A number of protrusions 3 are formed on the inner peripheral surface of the female member 2. In the present invention, these protrusions 3 are formed into wart-like shapes as shown in FIGS. As shown in FIGS. 3 and 4, it has a horizontally elongated shape.

As a result, the exhaust path for the internal air during the insertion period is shaped, and especially by forming the shape as shown in FIGS. 3 and 4, escape can be appropriately prevented.

Although the illustrated example shows an example in which the convex portion 3 is formed on the inner circumferential surface of the female member 2, it is of course possible to form the convex portion 3 on the outer circumferential surface of the male member 1.

However, as the material of the member, it is necessary to use an elastic resin such as rubber, acrylic resin, nylon 6, nylon 6-6, etc., which can be formed even if it becomes an undercut.

According to the device for attaching a decorative frame to a speaker box of the present invention, since a large number of convex portions to be formed on the outer circumferential surface of the male member or the inner circumferential surface of the female member are wart-like or horizontally elongated, both members When fitted, the function of discharging the internal air is not impaired in any way, the fitting is easily and accurately carried out, and there is no risk of it being pulled out unnecessarily.

[Brief explanation of the drawing]

The drawings show an embodiment of the device for attaching a decorative frame to a speaker box according to the present invention, FIG. 1 is a partial sectional view, FIG. 2 is a plan view of the female member, and FIG. 3 is another example of the structure. A partial sectional view of the female member, and FIG. 4 is a plan view of the same. 1...Male member, 2...Female member, 3...Convex portion.
