Abstract
Abstract A sign holder is disclosed which has a generally flat base of resilient material and two projections thereon. The first projection has a convex, sloped side surface, and the second projection has a corresponding concave, sloped side surface spaced from the convex side surface of the first projection. An arcuate wedge-shaped trough is formed between the side surfaces of the projections. The edge of a sign card or board is inserted in the trough and removably held upright thereby. The wedge shape of the trough and the resilient material of the base combine to firmly grip the edge of the sign card.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A sign holder, comprising: a generally flat resilient base; a first projection on the base having a convex, sloped side surface; a second projection on the base having a concave, sloped side surface spaced apart from the convex side surface of the first projection forming an arcuate wedge-shaped trough therebetween for the insertion of the edge of a sign, the second projection capable of slight movement away from the first projection by bending the resilient base to widen the trough upon the insertion of the edge of a sign; and two strips of adhesive beneath the base extending in the same general direction with and located on either side of the trough to permit the resilient base to be bent.
Claim 2
Dependent Claim
120 words
A sign holder, comprising: a generally flat resilient base; a first projection on the base having a convex, sloped side surface; a second projection on the base having a concave, sloped side surface spaced apart from the convex side surface of the first projection forming an arcuate wedge-shaped trough therebetween for the insertion of the edge of a sign, the second projection capable of slight movement away from the first projection by bending the resilient base to widen the trough upon the insertion of the edge of a sign; and two strips of adhesive beneath the base extending in the same general direction with and located on either side of the trough to permit the resilient base to be bent.
Claim 3
Dependent Claim
149 words
A sign holder comprising: a generally flat resilient base; a first oval-shaped projection on the base having a rounded upper portion and having a convex, sloped side surface; a second crescent-shaped projection on the base having a rounded upper portion and having a concave, sloped side surface spaced apart from the convex side surface of the first projection, an arcuate wedge-shaped trough formed between the convex side surface and the concave side surface, the trough adapted for insertion of a sign; and two strips of adhesive beneath the base extending in the same general direction with and on either side of the trough for mounting the holder to an external surface, the upper portion of the second projection capable of slight movement away from the upper portion of the first projection by bending the resilient base to widen the trough upon the insertion of the edge of a sign.
Claim 4
Dependent Claim
149 words
A sign holder comprising: a generally flat resilient base; a first oval-shaped projection on the base having a rounded upper portion and having a convex, sloped side surface; a second crescent-shaped projection on the base having a rounded upper portion and having a concave, sloped side surface spaced apart from the convex side surface of the first projection, an arcuate wedge-shaped trough formed between the convex side surface and the concave side surface, the trough adapted for insertion of a sign; and two strips of adhesive beneath the base extending in the same general direction with and on either side of the trough for mounting the holder to an external surface, the upper portion of the second projection capable of slight movement away from the upper portion of the first projection by bending the resilient base to widen the trough upon the insertion of the edge of a sign.
