Abstract

A structure for supporting a sign board is disclosed. The structure includes: a post clamp having a pair of arched clamping bands which are hingedly coupled and joined to each other by a fastening element, at least one clamping band having a pillar; a hanger having a socket pipe joined to the pillar of the post clamp, a support bar inserted into the socket pipe and joined by a fastening element, the support bar having an axial coupling groove; at least one connector having a first coupling plate with a coupling bulge adapted to be fitted into the coupling groove of the support bar and with a first arched hinge holder, and a second coupling plate coupled to the first coupling plate having a second arched hinge holder; and a sign board having a coupling bulge and a guide slot through which the hinge holders of the connector pass.

Claims

1. An apparatus for supporting a sign board, comprising:

a post clamp including at least a first arched clamping band and second arched clamping band that are hingedly coupled to each other at their adjacent end portions and joined to each other by a fastening element at their free ends to be assembled around a periphery of a post, at least one arched clamping band being provided at its outer surface with a pillar protruding therefrom that includes a groove on a front surface thereof; and

a connecting holder with a coupling bulge adapted to be fitted into the coupling groove of the pillar and a channel for receiving the sign board.

2. The apparatus of claim 1, wherein the at least first arched clamping band and second arched clamping band include a hinge groove and a hinge bulge at a first end and a flange at a second end such that the hinge grooves and the hinge bulges may be operably interconnected to each other.

3. The apparatus of claim 1, wherein the at least one fastening element is a nut and bolt.

4. The apparatus of claim 2, wherein the post clamp further includes at least one auxiliary clamping band coupled between the first clamping band and second clamping band, the auxiliary clamping band being provided at opposite ends thereof with a hinge groove and a hinge bulge corresponding to each other, and has a circumference smaller than that of any of the first and the second clamping bands, whereby the auxiliary clamping band is selectively coupled between the first and the second clamping bands according to the size of the post.

5. The apparatus of claim 2, wherein the at least first and second arched clamping bands are provided adjacent to the hinge groove with at least one retaining screw that is embedded into the hinge groove to prevent the hinge bulge from being separated from the hinge groove.

6. The apparatus of claim 1, wherein the post clamp and the connecting holder are made of nonferrous metal.

7. The apparatus of claim 6, wherein the nonferrous metal is aluminum.

8. An apparatus for supporting a sign board, comprising:

a post clamp including at least a first arched clamping band and second arched clamping band each hingedly interconnected to at least one third arched clamping band, the first and second arched clamping band joined to each other by a fastening element at their free ends to be assembled around a periphery of a post, the at least third arched clamping band being provided at its outer surface with a pillar protruding therefrom that includes a groove on a front surface thereof; and

a connecting holder with a coupling bulge adapted to be fitted into the coupling groove of the pillar and a channel for receiving the sign board.

9. The apparatus of claim 8, wherein the at least first arched clamping band and second arched clamping band include a hinge groove and a hinge bulge at a first end and a flange at a second end such that the hinge grooves and the hinge bulges may be joined to a hinge bulge or hinge groove on the ends of the at least one third arched clamping band.

10. The apparatus of claim 9, wherein the post clamp further includes at least one auxiliary clamping band coupled between at least one of the first arched clamping band and second arched clamping band and the at least one third arched clamping band, said auxiliary clamping band is provided at its opposite ends with a hinge groove and a hinge bulge corresponding to each other and has a circumference smaller than that of any of the first, second, and third arched clamping bands, whereby the auxiliary clamping band is selectively coupled to the post clamp according to a size of the post.

11. The apparatus of claim 9, wherein a plurality of third clamping bands are provided, and wherein the post clamp further includes at least one auxiliary clamping band coupled between two of the plurality of third arched clamping bands, said auxiliary clamping band is provided at its opposite ends with a hinge groove and a hinge bulge corresponding to each other and has a circumference smaller than that of any of the first, second, and third arched clamping bands, whereby the auxiliary clamping band is selectively coupled to the post clamp according to a size of the post.

12. The apparatus of claim 9, wherein the auxiliary clamping band is provided at both ends adjacent to the hinge groove with at least one retaining screw that are embedded into the hinge groove to prevent the hinge bulge from being separated from the hinge groove.

13. The apparatus of claim 8, wherein the post clamp and the connecting holder are made of nonferrous metal.

14. The apparatus of claim 13, wherein the nonferrous metal is aluminum.

15. The apparatus of claim 8, wherein the at least one of the first arched clamping band and the second arched clamping band being provided at its outer surface with a pillar protruding therefrom that includes a groove on a front surface thereof.
