Description

[Detailed Description of the Invention] This invention relates to the structure of a speaker mount for mounting a speaker in a ceiling, wall, etc. in an embedded manner.

When adding conventional speakers to the ceiling by recessing them,
Various methods have been implemented for additions, taking into consideration workability and maintainability.

One way to do this is to fit a cylindrical case into a circular speaker mounting hole drilled in the ceiling, sandwich the ceiling plate between the flange at the bottom of the cylindrical case and the legs of the L-shaped fixture on the outside of the cylindrical case. and an L-shaped fixture are fastened from the inside with thumbscrews, and a speaker with a panel is often attached to and detachable from the cylindrical case using a spring.

The outer diameter of this cylindrical case is slightly smaller than the inner diameter of the circular speaker mounting hole, and is constant throughout.
When fitting a cylindrical case into a mounting hole, if a fixture is attached to the outside of the case in advance, the legs bent outward at the lower end of the fixture will get caught in the hole and become uneven. Therefore, it was necessary to push only the cylindrical case into the mounting hole and then insert the fixture from the inside of the case to the outside to add more.

However, since the work is carried out on a high ladder facing the ceiling, not only does the work not go smoothly, but during the installation work, thumb screws and fixings may fall into the ceiling or onto the indoor floor. They had to search in the ceiling or go down to pick things up on the floor, which greatly reduced work efficiency.

In view of these points, it is an object of the present invention to provide a speaker mount that can be easily added with less effort in terms of speaker electrical properties.

This invention will be explained in detail below based on the drawings showing one embodiment thereof.

The speaker mount of this invention consists of a polygonal support 3 and a plate-shaped fixture 4, as shown in FIGS. 1 and 2. 8,
It consists of 9 rows of vertical surfaces.

The lower end of the vertical surface 9 is bent outward at a right angle to form a seven-run section 10.

A slit 11 is provided in the longitudinal center of the inclined surface of 8, so that the plate-shaped fixture 4 can be applied from the outside and slidably secured with a wing screw 12 from the inside.

Hanging holes 13 are formed near both ends of the upper surface 7 of the untwisted support 3, so that springs 14 for hanging the speaker body 5 are suspended therefrom.

Accordingly, hook rings 15 are also provided at two arbitrary locations on the back surface of the speaker body 5.

However, in order to add a speaker electrical device consisting of a support and a fixing device with the structure described above to the speaker electrical hole 2 in the ceiling,
A fixture 4 is attached to the outside of the sprout support 3 through a slit 11 from inside the support 3 with a thumbscrew 12.

At this time, in order to prevent the lower end of the fixture 4 from getting caught in the electrical hole 2, it is temporarily fixed above the slit 11 to the extent that it does not protrude beyond the vertical surface 9 of the support 3, as shown in FIG.

The support 3 with the fixture 4 temporarily fixed in this manner is fitted into the speaker conductive hole 2 in the ceiling, and the flange portions 10 bent outward of the vertical surface 9 of the support are brought into contact with both lower surfaces of the ceiling plate 1. .

The position of the support 3 in the additional hole 2 is determined in this way, and then the thumbscrew 12 that temporarily fastened the fixture 4 to the outside of the support 3 is loosened to slide the slit 11 and the fixture 4 is removed. It is lowered along the slope 8 and the lower end is attached to the ceiling plate 1.
Place it on the top surface, hold the ceiling board 1 between this fixture 4 and the flange part 10 of the support 3, and tighten the thumbscrew 12 in the 7'n state to tighten the fixture 4 to the inclined surface 8. The support 3 is fixed within the additional hole 2.

After installing the speaker electrical device into the electrical hole 2 of the ceiling speaker, the spring 14 suspended from the top surface of the support 3 is engaged with the hooking ring 15 on the back side of the speaker body 5 having the front panel 6, thereby attaching the speaker to the electrical hole 2 of the ceiling speaker. The main body 5 can be loaded into the electrical hole 2 very easily, and the front panel 6 of the speaker main body 5 completely covers the flange portion 10 of the support 3 that is buttoned on the lower side of the ceiling panel. Old,
The speaker body 5 can be beautifully added to the ceiling.

In the above embodiment, the fixture 4 is shown as a simple plate-like fixture, but it may also be in an L-shape with the lower end bent outward.

However, since the fixture 4 moves along the inclined surface 8 as shown in the figure, its lower end extends considerably outward from the vertical surface 9 of the support 3 and comes into contact with the ceiling plate 1 and is clamped together with the flange portion 10, so that its lower end does not necessarily have to be L-shaped.

In order to securely fasten the old fixture 4 to the thumbscrew 12 on the inclined surface 8 of the support 3, a nut may be secured to the outside of the screw hole of the fixture 4 and then pressed.

This idea consists of the above-mentioned structure, and is a simple method in which the fixture is movably fastened along the lower end flange of the support fitted into the speaker conductor hole in the ceiling and the slit made in the inclined surface. The attachment tool can be reliably clamped with just one operation.

The assembled support can be easily obtained by processing band-shaped sheet metal or molding resin, and the fixing device can be smoothly fitted into the ceiling hole even if it is temporarily fixed on the outside of the slope of the support in advance. This reduces the amount of work required on the underside of the ceiling during installation, which simplifies the work and further improves work efficiency without having to worry about dropping fixings or thumbscrews when adding them. It has many effects such as:
