Abstract
Abstract A safety rail and a connector for adjustably attaching an end piece to a tubular bar of the type used in safety rails. The end piece has a recess adapted to receive an end of the tubular bar and an opening for receiving a screw which passes through the end piece into the bottom of the recess to engage in the connector. The connector includes a crossbar having a lug at each of its ends. The lugs extend outwardly for attaching the connector to an inside surface of the bar. An integral tubular portion of the connector extends inwardly from the crossbar to define a threaded opening to receive the screw for drawing the end pieces to the bar. Each of the ends of the rail has one connector and one end piece.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
288 words
A safety rail for attachment to a wall, floor and the like, the safety rail comprising: a tubular end portion having inner and outer surfaces of respective predetermined internal and external diameters; an end piece comprising: a flanged portion having a transverse rear face for placing in contact with the wall, and a front face parallel to the rear face, the flanged portion further defining at least one axial hole extending through the flanged portion for receiving a fastener to attach the rail to the wall; a boss extending outwardly from said front face, the boss defining a cylindrical recess of a diameter substantially equal to said external diameter, and containing an end of said tubular portion, the axis of the recess being normal to respective planes containing the front and rear faces and the end piece further defining an opening extending between said faces and coaxial with said recess; and a connector permanently attached to the inner surface of the end portion, the connector comprising: a crossbar extending transversely; a pair of lugs extending axially towards the end piece, the lugs being integrally attached to respective ends of the crossbar and curved in cross section for face-to-face engagement with said inner surface, the lugs being attached permanently to said inner surface; and a tubular portion integrally attached to the crossbar and extending coaxially with the recess and away from the end piece to define a threaded opening extending axially through the crossbar and tubular portion; and a locking screw extending through the opening in the end piece and threadably engaged in said threaded opening whereby said end piece is attached to said tubular end portion in a preferred angular position with respect to said tubular end portion.
Claim 2
Dependent Claim
288 words
A safety rail for attachment to a wall, floor and the like, the safety rail comprising: a tubular end portion having inner and outer surfaces of respective predetermined internal and external diameters; an end piece comprising: a flanged portion having a transverse rear face for placing in contact with the wall, and a front face parallel to the rear face, the flanged portion further defining at least one axial hole extending through the flanged portion for receiving a fastener to attach the rail to the wall; a boss extending outwardly from said front face, the boss defining a cylindrical recess of a diameter substantially equal to said external diameter, and containing an end of said tubular portion, the axis of the recess being normal to respective planes containing the front and rear faces and the end piece further defining an opening extending between said faces and coaxial with said recess; and a connector permanently attached to the inner surface of the end portion, the connector comprising: a crossbar extending transversely; a pair of lugs extending axially towards the end piece, the lugs being integrally attached to respective ends of the crossbar and curved in cross section for face-to-face engagement with said inner surface, the lugs being attached permanently to said inner surface; and a tubular portion integrally attached to the crossbar and extending coaxially with the recess and away from the end piece to define a threaded opening extending axially through the crossbar and tubular portion; and a locking screw extending through the opening in the end piece and threadably engaged in said threaded opening whereby said end piece is attached to said tubular end portion in a preferred angular position with respect to said tubular end portion.
Claim 3
Dependent Claim
181 words
In a safety rail having a tubular end portion including inner and outer surfaces of respective predetermined internal and external diameters, an end piece defining openings for receiving fasteners to attach the end piece to a wall and the like, and means coupling the end piece to the end portion, the improvement wherein the coupling means comprises: a connector having a crossbar extending transversely, a pair of lugs extending axially towards the end piece, the lugs being integrally attached to respective ends of the crossbar and curved in cross section for face-to-face engagement with said inner surface, the lugs being attached permanently to said inner surface, and a tubular portion integrally attached to the crossbar and extending coaxially with the tubular end portion and away from the end piece to define a threaded opening extending axially through the crossbar and tubular portion; and a locking screw extending through the end piece and threadably engaged in said threaded opening whereby said end piece is attached to said tubular end portion for angular location at a preferred position relative to the end portion.
Claim 4
Dependent Claim
181 words
In a safety rail having a tubular end portion including inner and outer surfaces of respective predetermined internal and external diameters, an end piece defining openings for receiving fasteners to attach the end piece to a wall and the like, and means coupling the end piece to the end portion, the improvement wherein the coupling means comprises: a connector having a crossbar extending transversely, a pair of lugs extending axially towards the end piece, the lugs being integrally attached to respective ends of the crossbar and curved in cross section for face-to-face engagement with said inner surface, the lugs being attached permanently to said inner surface, and a tubular portion integrally attached to the crossbar and extending coaxially with the tubular end portion and away from the end piece to define a threaded opening extending axially through the crossbar and tubular portion; and a locking screw extending through the end piece and threadably engaged in said threaded opening whereby said end piece is attached to said tubular end portion for angular location at a preferred position relative to the end portion.
Claim 5
Dependent Claim
53 words
A safety rail as claimed in claim 1 in which the crossbar is generally rectangular, each of the lugs being attached to a corresponding one of the shorter sides of the rectangular crossbar so that the longer sides of the crossbar are exposed for gripping the connector during assembly of the safety rail.
Claim 6
Dependent Claim
52 words
Apparatus as claimed in claim 2 in which said connector crossbar is generally rectangular, each of said lugs being attached to a corresponding one of the shorter sides of the rectangular crossbar to that the longer sides of the crossbar are exposed for gripping the connector during assembly of the safety rail.
