Abstract

A rail fitting for marine application comprises first and second rail fitting parts designed to slide together on opposite sides of a rail and thereby interlock. Each rail fitting part is provided with an arcuate concavity designed to fit around a rail, a first end on one side of the concavity designed to interlock with a first end of the other rail fitting part, and a second end on an opposite side of the concavity designed to be fastened to a second end of the other rail fitting part by a fastener. The first end of the first rail fitting part is provided with an arcuate cavity having a degree of wrap of at least 180°. The first end of the second rail fitting part is provided with a hinge arm having an arcuate end formed to fit and rotate within the arcuate cavity in the first end of the first rail fitting part. The concavity provided in each rail fitting part provides a combined arcuate concavity through which a railing may extend.

Claims

1. A rail fitting which comprises first and second rail fitting parts designed to slide together on opposite sides of a rail and thereby interlock, and fastening means for fastening the two rail fitting parts together around a rail;

each rail fitting part being provided with an arcuate concavity designed to fit around a rail, a first end on one side of the concavity designed to interlock with a first end of the other rail fitting part, and a second end on an opposite side of the concavity designed to be fastened to a second end of the other rail fitting part by said fastening means;

the first end of said first rail fitting part being provided with an arcuate cavity having a degree of wrap of at least 180°

;

the first end of said second rail fitting part being provided with a hinge arm having an arcuate end formed to fit and rotate within the arcuate cavity in the first end of said first rail fitting part;

said hinge arm being so constructed and arranged with respect to said arcuate cavity that the arcuate end of said hinge arm may be longitudinally inserted into said arcuate cavity whereby the first and second rail fitting parts are interlocked.

2. The rail fitting of claim 1 wherein the arcuate cavity in the first end of the first rail fitting part having a degree of wrap between about 225°

and 270°

; and

wherein the degree of wrap of the end of the hinge arm of the second rail fitting part is slightly greater than the degree of wrap of said arcuate cavity whereby said first and second rail fitting parts may be rotated a few degrees inward and outward with respect to one another after they have been interlocked.

3. The rail fitting of claim 2 wherein the concavity provided in each rail fitting part provides a combined arcuate concavity of circular configuration when the first and second rail fitting parts are interlocked;

and wherein a V-shaped gap is provided that opens into the combined arcuate concavity, said V-shaped gap being so located and defined by adjacent edges of the interlocked first ends of the first and second rail fitting parts whereby the first and second rail fitting parts may be rotated in snug engagement with a railing that extends through the combined arcuate concavity.

4. A rail fitting which comprises first and second rail fitting parts designed to slide together on opposite sides of a rail and thereby interlock, and fastening means for fastening the two rail fitting parts together around a rail;

each rail fitting part being provided with a concavity designed to fit around a rail, a first end on one side of the concavity designed to interlock with a first end of the other rail fitting part in hinged connection, and a second end on an opposite side of the concavity designed to be fastened to a second end of the other rail fitting part by said fastening means;

the first end of said first rail fitting part having a hinge receiving means providing a semicylindrical arcuate cavity having a degree of wrap of at least 180°

, said arcuate cavity extending transversely through the first end of said first fitting part;

the first end of said second rail fitting part having hinge arm means providing an arcuate end formed to fit and rotate within the arcuate cavity in the first end of said first rail fitting part, said arcuate end being semicylindrical and extending transversely across the first end of said second rail fitting part;

said hinge arm means being so constructed and arranged with respect to said hinge receiving means that the arcuate end of said hinge arm means may be longitudinally inserted into said arcuate cavity whereby the first and second rail fitting parts are interlocked in said hinged connection.

5. The rail fitting of claim 4 wherein the arcuate cavity of said hinge receiving means has a degree of wrap between about 225°

and 270°

; and

wherein the degree of wrap of the arcuate end of the hinge arm means is slightly greater than the degree of wrap of said arcuate cavity whereby said first and second rail fitting parts may be rotated a few degrees inward and outward with respect to one another after they have been interlocked.

6. The rail fitting of claim 5 wherein the concavity provided in each rail fitting part provides a combined arcuate concavity of circular configuration when the first and second rail fitting parts are interlocked;

and wherein a V-shaped gap is provided in the first ends of the first and second rail fitting parts that opens into the combined arcuate concavity, said V-shaped gap being so located and defined by adjacent edges of the interlocked first ends of the first and second rail fitting parts with the apex of the V-shaped gap abutting the arcuate end of said hinge arm means whereby the first and second rail fitting parts may be rotated in snug engagement with a railing that extends through the combined arcuate concavity.

7. The rail fitting of claim 4 wherein the second ends of each rail fitting part are provided with attachment means located outwardly of said fastening means and so constructed and arranged that an object may be attached to said attachment means when said rail fitting parts are fastened to a rail whereby said rail fitting joins the object to the rail.
