Abstract

An improved railing connection and method of manufacture and assembly for use in assembling railings. A railing connection fastener is secured to one railing member and is concealed within the proximal end of a second railing member. The proximal end of the second railing member is shaped to fit the shutting profile of the first railing member, thereby resisting rotational movement around the proximal-distal axis of the second railing member. The railing connection fastener is secured to the second railing member, thereby resisting movement along the proximal-distal axis of the second railing member. The contour of the proximal end of the second railing member is shaped to fit the profile of the first railing member. The use of the connection fastener and the contour of the proximal end of the second railing member create a smooth, continuous joint with limited complex manufacture.

Description

RELATED APPLICATIONS

This application is the non-provisional application of U.S. Provisional Application No. 61/788,660 filed Mar. 15, 2013, invented by Paul Breuer, and upon which the present application relies for priority.

FIELD OF INVENTION

The present invention pertains to railing systems and railing assembly, and components therefor, which have railings interconnected at various angles, and more particularly is directed to an improved pipe railing system.

DESCRIPTION OF THE RELATED ART

Railing assemblies, bannisters and railing systems are known its the art, serving as barriers to elevated platforms, handholds for stairways, and methods to control the direction and flow of pedestrians, among other uses. They typically comprise railings interconnected lacking a streamlined appearance, or require the services of a welder to join vertical posts to horizontal railing members.
Smooth, continuous joints are desirable where the exterior surfaces of the pipe members meet. Common quick-connect style railing connectors (as described in U.S. Pat. No. 6,568,658, issued to Strome, May 23, 2003) do not provide the smooth continuous joints sought, such as where the connector body is visible. Other methods of connecting railing members are also expensive, require significant tooling, machining, molding, welding, other complex manufacture, are unreliable, time consuming, expensive and may require skilled assembly or employ relatively complex mechanical devices with undesirable numbers of parts and assembly.

SUMMARY OF THE INVENTION

The object of the present invention is to solve the above mentioned problems by providing a simple railing system connection, requiring few parts, easily manufactured, and which cm be assembled without welding. Accordingly, the present invention is directed to an improved railing connection that is easily produced, providing a smooth and continuous joint, and which takes advantage of the properties of the railings in the joist connection. The shaped joint connection, whereby the end of one railing member is mated to the contours of the railing member it intersects, provides significant features of the improved railing system connection. These and other objects, features and advantages of the invention are provided by the improved railing system disclosed herein.
A preferred configuration of the invention, two hollow tabular railing members are joined by the use of a unique U-shaped railing connection fastener, one railing member end being shaped to the contours of another railing member, the railing connection fastener disposed within the body of the first railing member, secured to the body of the first railing member by means of a simple screw fastener, and secured to the second railing member by means of a simple screw fastener. The resulting railing system provides a structurally rigid barrier, simple to assemble, aesthetically pleasing, and easy to install. These and other features of the invention will become apparent upon a more detailed description of preferred embodiments of the invention as described below.
