Hinge assembly
First Claim
1. A hinge device, said hinge device comprising a plurality of hinge units, each of said hinge units having:
- a body portion, said body portion having a first end, a cylindrical region, a mid region, a reduced region, and a second end, said first end being opposite said second end,said cylindrical region being at said first end of said body portion and having an elongated interior circular channel, an elongated groove within said mid region, said elongated groove extending radially from said elongated circular channel through at least a major portion of said mid region of said body portion toward said second end,said reduced region having a recessed region extending from said mid region to said second end of said body portion, said reduced region having a thickness less than the thickness of said mid region of said body portion, thereby providing a shoulder at the juncture of said mid region and said reduced region,a first bolt passage means, said first passage extending through said mid region and having its axis perpendicular to the plane of said elongated groove, thereby intersecting said elongated groove;
a second bolt passage mans, said second passage extending through said reduced region and having its axis parallel to the axis of said first passage means;
said hinge device also comprising;
a plurality of first bolt means, each of said first bolt means being positioned in one of said first bolt passage means, whereby tightening a first bolt means compresses a mid region and a corresponding cylindrical region.

Abstract
A hinge member comprising a plurality of hinge units, each unit having a body portion, with a slotted region and an annular region. The annular region is formed by an elongated circular channel in a cylindrical portion of the hinge. An elongated groove in the slotted region of the body has a region of reduced thickness relative to the slotted region. The elongated groove intersecting with the elongated channel, with a first passage in the slotted region and a second passage in the region of reduced thickness. A ridge is thereby provided between the slotted region and the region of reduced thickness. The axis of the first passage means is parallel to the axis of the second passage and parallel to the axis of the elongated channel. The first passage has its axis perpendicular to the first surface of the slotted region.

1. A hinge device, said hinge device comprising a plurality of hinge units, each of said hinge units having:
- a body portion, said body portion having a first end, a cylindrical region, a mid region, a reduced region, and a second end, said first end being opposite said second end,
said cylindrical region being at said first end of said body portion and having an elongated interior circular channel, an elongated groove within said mid region, said elongated groove extending radially from said elongated circular channel through at least a major portion of said mid region of said body portion toward said second end, said reduced region having a recessed region extending from said mid region to said second end of said body portion, said reduced region having a thickness less than the thickness of said mid region of said body portion, thereby providing a shoulder at the juncture of said mid region and said reduced region, a first bolt passage means, said first passage extending through said mid region and having its axis perpendicular to the plane of said elongated groove, thereby intersecting said elongated groove; a second bolt passage mans, said second passage extending through said reduced region and having its axis parallel to the axis of said first passage means; said hinge device also comprising; a plurality of first bolt means, each of said first bolt means being positioned in one of said first bolt passage means, whereby tightening a first bolt means compresses a mid region and a corresponding cylindrical region. - View Dependent Claims (2, 3)

4. A display sign, said display sign comprising:
-
a first display board, a second display board, a plurality of hinge assemblies, and a rod member, each of said hinge assemblies comprising; a first pair of hinge members and a second pair of hinge members, each of said first pair of hinge members and said second pair of hinge members having; a body portion, said body portion having a first end, a cylindrical region, a mid region, a reduced region, and a second end, said first end being opposite said second end, said cylindrical region being at said first end of said body portion and having an elongated interior circular channel, an elongated groove within said mid region, said elongated groove extending radially from said elongated circular channel through at least a major portion of said mid region of said body portion toward said second end, said reduced region having a recessed region extending from said mid region to said second end of said body portion, said reduced region having a thickness less than the thickness of said mid region of said body portion, thereby providing a shoulder at the juncture of said mid region and said said reduced region, a first bolt passage means, said first passage extending through said mid region and having its axis perpendicular to the plane of said elongated groove, thereby intersecting said elongated groove; a second bolt passage means, said second passage extending through said reduced region and having it axis parallel to the axis of said first passage means; said display sign further comprising; a plurality of first bolt means, each of said first bolt means being positioned in one of said first bolt passage mans, whereby tightening a first bolt means compresses a mid region and a corresponding cylindrical region, said rod member passing through each said cylindrical channel and being dimensioned relative to each said cylindrical channel such that tightening of a first bolt means to compress a corresponding mid region, compresses a corresponding elongated groove and circular channel, preventing movement of said corresponding rod relative to said hinge member, and each of said board members being secured to said reduced thickness region of at least one hinge member of each pair of hinge members. - View Dependent Claims (5, 6, 7, 8, 9)
