Abstract
Abstract This invention relates to a means and method of hinging a glass door panel on an adjoining wall, either glass or non-glass. This invention uses a friction clamping method to secure the glass between surfaces lined with flexible gaskets. When torque is applied to the clamp screws, the flexible gaskets swell laterally to provide a large gripping surface area. The invention also includes an actuating mechanism that allows for wide range of rotation with absolute reputability. The actuating mechanism utilizes a main pivot roller that incorporates two indexing detents. A spring loaded sub pin roller rotates along the periphery of the main pivot roller providing a consistent index to each of the two detents.

Total Claims: 19
Claim 1
Independent Claim
253 words
A hinge for hinging a glass panel door to an adjacent supporting structure comprising: a tram body comprising a housing; a main pivot roller rotatably journaled in the housing and including a main body portion and narrowed opposite end portions; a sub pin roller rotatably journaled in the housing along the main body portion of the main pivot roller; a biasing member positioned in the housing pushing the sub pin roller into abutment with the main body portion of the main pivot roller; the main body portion of the main pivot roller including an indexing detent along its length into which the sub pin roller fits when in alignment, the indexing detent having angled sides and a bottom, the angled sides being spaced so that the sub-roller pin can be partially inserted into the indexing detent and contact each angled side at one point; a connector member attached to the tram body and having a component allowing connection of the hinge to an adjacent supporting structure; the opposite end portions each including an anchor portion having a pair of oppositely facing flat surfaces, of the main pivot roller extending outwardly of the tram body housing; and a clamp comprising first and second clamp halves which are adjustable to pull the clamp halves toward one another to clamp the glass panel doors, and receiver members to receive the anchor portions of the opposite end portions of the main pivot roller to prevent rotation or movement of the main pivot roller relative to the clamp.

Claim 3
Dependent Claim
19 words
The hinge of claim 1 wherein the main pivot roller has two or more indexing detents along its length.
Claim 4
Dependent Claim
14 words
The hinge of claim 1 wherein the clamp halves include recesses to receive gaskets.
Claim 5
Dependent Claim
39 words
The hinge of claim 1 wherein the connector member is a base plate which is connectable to the tram body, the base plate having apertures to allow it to be attached to the adjacent supporting structure by mounting members.
Claim 6
Dependent Claim
36 words
The hinge of claim 1 wherein the adjacent supporting structure is a glass panel and the connector member is a second clamp attached to the tram body to attach the tram body to the glass panel.
Claim 7
Dependent Claim
57 words
The hinge of claim 1 further comprising a raised portion on one of the connector member and the tram body, and a mating recess for the raised portion on the other of the connector member and the tram body, so that attachment of the connector member and the tram body resists rocking during operation of the hinge.
Claim 8
Dependent Claim
24 words
The apparatus of claim 1 further comprising the angles walls of the indexing detent are at or near ninety degrees relative to one another.
