Abstract

Provided is an interior building material having a high decorative presentation effect and an easy replacing capability of an organic EL panel. An organic EL panel is interposed between a mounting member and a decorative member. The mounting member is fixed to a wall surface of a fixed structure. The organic EL panel is directly or indirectly attachable to and detachable from the mounting member with power supply capability from a side of the mounting member. The decorative member covers an emission surface of the organic EL panel with presentation of a first pattern during non-lighting and with expression of a second pattern different from the first pattern during lighting.

Claims

1. An interior building material comprising:

a mounting member fixed to a wall surface of a fixed structure;

a decorative member; and

a plurality of planar light-emitting panels interposed between the mounting member and the decorative member,

wherein one of the plurality of planar light-emitting panels is directly or indirectly attachable to and detachable from the mounting member with capability of supplying power from the mounting member side,

wherein the decorative member covers across emission surfaces of the plurality of planar light-emitting panels, the decorative member presenting a first pattern during non-lighting,

wherein during lighting, the decorative member transmits emitted light from the emission surface through the decorative member,

wherein each of the planar light-emitting panels comprises;

a panel body; and

a fixing member,

the fixing member comprising;

a main body; and

a raised part disposed to a rear face side of the planar light-emitting panel and raised from the main body to the rear face side,

the raised part including a plurality of panel side engagement parts that protrude in a direction orthogonal to a raising direction of the raised part,

wherein two of the panel side engagement parts project in a direction separating from each other,

wherein the mounting member comprises;

a mounting side main body; and

a plurality of mounting side engagement parts,

two of the mounting side engagement parts projecting in a direction bringing close to each other, and

wherein mounting the planar light-emitting panel to the mounting member includes a process of sliding the planar light-emitting panel to a vertical direction to engage the two of the mounting side engagement parts with the two of the panel side engagement parts.

2. The interior building material according to claim 1, wherein during lighting, the decorative member transmits a part of emitted light from the emission surface through the decorative member to express a second pattern different from the first pattern.

3. The interior building material according to claim 1,

wherein the planar light-emitting panel is an organic EL panel,

wherein the decorative member includes a first surface facing to the emission surfaces of the planar light-emitting modules, and

wherein a distance between the first surface and the emission surface is 0 mm or more to 10 mm or less.

4. The interior building material according to claim 1, wherein the planar light-emitting panels are electrically connected with each other.

5. The interior building material according to claim 1,

wherein the decorative member is a plate material including a first pattern forming layer that forms the first pattern and a second pattern forming layer that forms a second pattern different from the first pattern,

wherein the first pattern forming layer faces to the second pattern forming layer in a thickness direction of the decorative member with a transparent resin in between, and

wherein the second pattern forming layer is located nearer to the planar light-emitting panel than the first pattern forming layer.

6. The interior building material according to claim 1,

wherein the mounting member comprises an attachment side engagement part while the planar light-emitting panel comprises a panel side engagement part engageable with the attachment side engagement part, and

wherein mounting the planar light-emitting panel to the mounting member includes a process of sliding the planar light-emitting panel to a vertical direction to engage the mounting side engagement part with the panel side engagement part.

7. The interior building material according to claim 6,

wherein the planar light-emitting panels are arranged side by side in a row in a lateral direction, and

wherein a distance between end faces of the adjacent planar light-emitting panels is 0 mm or more, and 10 mm or less, the end faces opposing to each other in an arranging direction.

8. The interior building material according to claim 1,

wherein the plurality of planar light-emitting panels are attached to the decorative member,

wherein the plurality of planner light-emitting panels includes a first and a second planar light-emitting panels, and

wherein attachment of the second planar light-emitting panel to the mounting member enables the first planar light-emitting panel to be indirectly attached to the mounting member while detachment of the second planar light-emitting panel from the mounting member enables the first planar light-emitting panel to be indirectly detached from the mounting member.

9. The interior building material according to claim 1,

wherein the decorative member comprises an insertion hole that can be inserted with a temporary fastening element, and

wherein insertion of the temporary fastening element into the insertion hole enables the decorative member to fix the planar light-emitting panel with the planar light-emitting panel inserted between the mounting member and the decorative member.

10. An interior building material comprising:

a mounting member fixed to a wall surface of a fixed structure;

a decorative member; and

a planar light-emitting panel interposed between the mounting member and the decorative member,

wherein the planar light-emitting panel is directly or indirectly attachable to and detachable from the mounting member with capability of supplying power from the mounting member side,

wherein the decorative member covers an emission surface of the planar light-emitting panel, the decorative member presenting a first pattern during non-lighting, and

wherein during lighting, the decorative member transmits a part of emitted light from the emission surface through the decorative member to express a second pattern different from the first pattern, the first pattern disappearing with heat generation accompanying lighting of the planar light-emitting panel.
