Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel device, in particular, a panel device that allows a lid to be easily and reliably fitted into a through hole formed in a panel, and furthermore, the lid can be loosely fitted into a through hole formed in a panel, and the inner circumferential surface of the through hole in the loosely fitted state. The present invention relates to a panel device in which the gap between the lid and the outer peripheral surface is made uniform.

A conventional panel device is constructed as shown in FIGS. 1 to 8.

That is, a panel 2 has a square through hole 1 in its center that penetrates the front and back surfaces, and a lid is attached to the back surface of the panel 2 so that its inner peripheral surface (inner edge) 3 slightly protrudes into the through hole 1. The receiver consists of a member 4 and a panel 2 as shown in Figures 3 and 4.
A square lid 5 that is loosely fitted into the through hole 1 and has a similar shape to the through hole.
and a lid fixing member 6 attached to the back surface of the lid 5 to fix the lid 5 to the panel 2 when the lid 5 is loosely fitted into the through hole 1, and the lid holder is attached to the inside of the member 4. A pair of notches 7 are formed on the lower circumferential surface of the lid 5 at a predetermined distance from each other and cut downward, and at the lower end of the back surface of the lid 5, a pair of notches 7 are formed at a predetermined distance from each other and downward from the lower end surface 8 of the lid 5. Some were provided with a hook member 9 that protruded from the top.

When the lid 5 is loosely fitted into the through hole 1 and fixed to the panel 2, the lower end of the lid 5 is inserted into the through hole 1 at an angle, as shown in FIG. After the lower end surface 8 of the lid 5 is brought into contact with the inner peripheral lower surface 10, the lid 5 is swung about the lower end surface 8 until it becomes vertical, and the hook member 9 is inserted into the cut γ. The lid 5 was fixed to the panel 2 by a lid fixing member 6.

In this fixed state, as shown in FIG. 6-7, the lower end surface 11 of the hook member 9 is in contact with the bottom surface of the notch 7, so that the outer peripheral surface of the lid 5 and the inner peripheral surface of the through hole 1 A uniform gap was formed between them.

However, in this case, when the lid 5 is swung vertically, the lower end of the hook member 9 comes into contact with the back surface of the member 4 near the bottom of the notch 7, causing the lid 5 to swing vertically. There were cases where it was not possible.

In this case, the lid 5 must be lifted slightly and then the lid 5 must be swung, making the work extremely troublesome.

In order to eliminate this drawback, as shown in FIG. 8, the length of the hook member 9 is made shorter than the depth of the notch 7 so that the lower end of the hook member 9 does not come into contact with the back surface of the lid holder member 4. It is also possible to do so.

However, with this configuration, since the lid 5 is swung with the lower end surface 8 of the lid 5 in contact with the lower inner surface 10 of the through hole 1, the paint on the surface of the panel 2 may be scraped off.
There is a drawback that the surface of the panel 2 is scratched, making the panel 2 prone to rust and deteriorating its aesthetic appearance. Since the entire surface is in contact with the lower inner circumferential surface 10 of the hole 1, the gap formed between the inner circumferential surface of the through hole 1 and the outer circumferential surface of the lid 5 becomes uneven, resulting in a disadvantage that the aesthetic appearance is significantly deteriorated. .

The present invention has been made to eliminate the above-mentioned drawbacks.
The purpose is to provide a panel device in which the lid can be easily and reliably attached and removed, and the gap between the lid and the hole is uniform all around.

In order to achieve the above object, the present invention provides a flat engaged surface located between the lowermost inner edge of a square through hole formed in a panel and the lowermost inner edge of a lid receiving member attached to the back surface of the panel. A T-shaped notch is formed in the lid receiving member, and a locking member provided on the back side of the lid is formed in a T-shape so as to be positioned at the same position as the lowermost end of the lid and engaged with the surface to be secured. and the gap between the lower end of the locking member and the bottom of the notch formed at the inner edge of the lowermost part of the lid receiving member is set to be larger than the dimension from the inner edge of the through hole to the engaged surface. That's what I did.

An embodiment of the present invention will be described below with reference to FIGS. 9 to 15.

First, reference numeral 15 denotes a panel, and a square through hole 16 is formed in the center of the panel 15, passing through the front and back surfaces of the panel 15.

On the back surface of the panel 15, there are a top plate 17 whose lower end slightly protrudes into the through hole 16, a pair of side plates 18 and 19 whose side ends slightly protrude into the through hole 16, and an upper end thereof. A lower plate 20 that slightly protrudes into the through hole 16 is attached.

The above-mentioned upper plate 17, side plates 18, 19, and lower plate 20 collectively constitute a lid holder member 21.

As shown in detail in FIG. 11, a pair of notches 22 are formed at the inner edge of the lower plate 20, spaced apart from each other by a predetermined distance and extending downward.

This notch 22 is formed between the inner edge of the lower plate 20 and the inner lower surface 23 of the through hole 16 slightly above the inner peripheral lower surface 23 of the through hole 16 .
A flat engaged surface 24 extending parallel to the inner circumferential lower surface 23 is formed adjacent to both ends of the engaging surface 24, so that the entire surface has a substantially T-shape.

25 is a lid that can be loosely fitted into the through hole 16;
As shown in FIG. 12, a pair of T-shaped locking members 26 are attached to the lower end of the back surface of the lid 25 at a predetermined distance from each other. The retaining surfaces 28 are located on the same plane.

A pair of lid retaining members 29 are attached to the upper part of the lid 25 at a predetermined distance from each other, and the lid retaining members 29 can fix the lid 25 to the panel 15 when the lid 25 is loosely fitted into the through hole 16. It's been like that.

Next, the case where the lid 25 is attached to the panel 15 will be described.

First, the lower end of the lid 25 is inserted into the through hole 16 at an angle as shown in FIG.
is engaged with the engaged surface 24 of the notch 22.

Next, the lid 25 is swung around the engaging surface 28 of the locking member 26 until it becomes vertical, and as shown in FIGS. let

At this time, the center of swing of the lid 25 is aligned with the inner peripheral lower surface 2 of the through hole 16.
3, the lower end surface 27 of the lid 25 does not engage with the inner peripheral lower surface 23 of the through hole 16.

Therefore, the paint on the panel 15 will not be scraped off or the panel 15 will not be damaged.

Moreover, since the distance between the bottom surface of the locking member 26 and the engaging surface 28 is smaller than the distance between the bottom surface of the notch 22 and the engaged surface 24, the lower end of the locking member 26 is lowered. The locking member 26 does not come into contact with the back surface of the plate 20.
is easily inserted into the notch 22.

Furthermore, the positional relationship between the lid 25 and the through hole 16 is such that the engaged surface 2
4 and the inner circumferential lower surface 23 of the through-hole 16. Therefore, by setting the distance between the engaged surface 24 and the inner circumferential lower surface 23 to an appropriate value, the outer circumferential surface of the lid 25 and the through-hole 1
6 can be made uniform.

Next, the lid 25 is fixed to the panel 15 by the lid fixing member 29.

As explained above, according to the present invention, the operation of loosely fitting the lid into the through hole is significantly facilitated.

Moreover, it does not scrape off the paint on the panel or damage the panel.

Furthermore, the gap formed between the outer circumferential surface of the lid and the inner circumferential surface of the through hole can be made uniform, and the aesthetic appearance is significantly improved.
