Abstract

A topboard reflection preventer for a grand piano, which is capable of positively preventing lighting from being reflected by an open topboard, while maintaining excellent appearance of a piano body. The topboard reflection preventer for a grand piano is attached to an openable and closable topboard formed by a topboard rear and a topboard front, and prevents lighting from above from being reflected by the topboard in a state of the topboard held open in an inclined position. The topboard reflection preventer includes a reflection preventer body attached to the topboard rear and the topboard front folded onto the topboard rear, in a state covering whole upper surfaces of the topboard rear and the topboard front, and a holding member for holding the reflection preventer body so as to prevent the reflection preventer body from falling off the topboard held open in the inclined position.

First claim

What is claimed is:

1. A topboard reflection preventer for a grand piano, which is attached to an openable and closable topboard formed by a topboard rear and a topboard front, so as to prevent lighting from above from being reflected by the topboard in a state in which the topboard is held open in an inclined position, comprising:
a reflection preventer body configured to be attached to the topboard rear and the topboard front folded onto the topboard rear, in a state covering whole upper surfaces of the topboard rear and the topboard front; and
holding means configured to hold the reflection preventer body so as to prevent the reflection preventer body from falling off when the topboard held open in the inclined position, wherein the reflection preventer body includes:
a topboard rear cover section configured to cover the upper surface of the topboard rear, and
a topboard front cover section integrally formed with the topboard rear cover section and configured to cover the upper surface of the topboard front folded onto the topboard rear, and wherein
the topboard rear cover section has a shape substantially the same as a shape of the upper surface of the topboard rear, and wherein the topboard front cover section has a shape substantially the same as a shape of the upper surface of the topboard front and is formed such that the topboard front cover section is continuous with a right front end of the topboard rear cover section and extends rightward.

2. The topboard reflection preventer according to claim 1 , wherein the reflection preventer body is configured to be removably attached to the topboard.

3. The topboard reflection preventer according to claim 1 , wherein the holding means has an adhesive member and is provided on one of the reflection preventer body and the topboard so as to hold the reflection preventer body in a state affixed to the upper surface of the topboard rear and/or the topboard front.

4. A topboard reflection preventer for a grand piano, which is attached to an openable and closable topboard formed by a topboard rear and a topboard front, so as to prevent lighting from above from being reflected by the topboard in a state in which the topboard is held open in an inclined position, comprising:
a reflection preventer body configured to be attached to the topboard rear and the topboard front folded onto the topboard rear, in a state covering whole upper surfaces of the topboard rear and the topboard front; and holding means configured to hold the reflection preventer body so as to prevent the reflection preventer body from falling off when the topboard held open in the inclined position, wherein the holding means has a holding member which is provided on a periphery of the reflection preventer body such that the holding member extends along the periphery, so as to hold the periphery in a state extending around-onto a lower surface of the topboard rear and/or a lower surface of the topboard front.

5. A topboard reflection preventer for a grand piano, which is attached to an openable and closable topboard formed by a topboard rear and a topboard front, so as to prevent lighting from above from being reflected by the topboard in a state in which the topboard is held open in an inclined position, comprising:
a reflection preventer body configured to be attached to the topboard rear and the topboard front folded onto the topboard rear, in a state covering whole upper surfaces of the topboard rear and the topboard front; and holding means configured to hold the reflection preventer body so as to prevent the reflection preventer body from falling off when the topboard held open in the inclined position and, wherein the holding means has a latch member which is attached to a predetermined portion of the reflection preventer body, and is locked to a locking portion formed on the lower surface of the topboard rear, in a state extending from above onto the lower surface of the topboard rear.

6. The topboard reflection preventer according to claim 5 , wherein the reflection preventer body includes:
a topboard rear cover section configured to cover the upper surface of the topboard rear, and
a topboard front cover section integrally formed with the topboard rear cover section and configured to cover the upper surface of the topboard front folded onto the topboard rear.

7. The topboard reflection preventer according to claim 6 , wherein the topboard rear cover section has a shape substantially the same as a shape of the upper surface of the topboard rear, and wherein the topboard front cover section has a shape substantially the same as a shape of the upper surface of the topboard front and is formed such that the topboard front cover section is continuous with a right front end of the topboard rear cover section and extends rightward.
