Abstract

A mark carrying plate of metal or plastic material is bonded on the rough surface of an article such as a piano frame of cast metal, with an elastic substance interposed between the plate and the article. The mark carrying plate may be provided with a recess which receives the elastic substance so as to conceal the elastic substance therein. Interposition of the elastic substance between the plate and the article enhances the bonding strength therebetween and serves to absorb shock vibrations transmitted from the article to the plate.

Claims

1. In a piano or the like, a mark affixing structure for affixing a free, unrestrained mark carrying member to a roughsurfaced frame which is subjected to impacts and/or vibrations, said mark affixing structure comprising:

a free, unrestrained mark carrying member;

silicon rubber material interposed between said rough-surfaced frame and said mark carrying member with a surface of said silicon rubber material conforming in shape to the surface of said rough-surfaced frame; and

an epoxy resin adhesive bonding a surface of said silicon rubber material to said rough-surfaced frame and another surface of said silicon rubber material to said mark carrying member.

2. The structure according to claim 1 wherein said silicon rubber material is substantially non-porous.

3. In a piano or the like, a mark affixing structure for affixing a free, unrestrained mark carrying member to a rough-surfaced frame which is subjected to impacts and/or vibrations, said mark affixing structure comprising:

a free, unrestrained mark carrying member;

a recess formed in at least one of said mark carrying member and said frame;

silicon rubber material located within the boundaries of said recess and interposed between said frame and said mark carrying member with a surface of said silicon rubber material substantially conforming in shape to the surface of said frame, the thickness of said silicon rubber material in the direction of the depth of said recess being greater than the depth of said recess; and

an epoxy resin adhesive bonding a surface of said silicon rubber material to said frame and another surface of said silicon rubber material to said mark carrying member.

4. The structure according to claim 3 wherein said recess is formed in said mark carrying member.

5. The structure according to claim 4 wherein said mark carrying member has a peripheral projection directed toward said frame and defining said recess, a clearance being defined between said silicon rubber material and said peripheral projection.
