Abstract
Uprights and lateral or connecting posts to be used in conjunction with a gangway or other fall restraint equipment where the uprights and posts are created by cutting portions of integral, continuous pieces of tubular metal rather than welding smaller pieces of stock material together. Sidepost assemblies or handrails are created by connecting the uprights and posts together.
Claims22
A method for assembly of a gangway having at least one handrail and a support, the method comprising:
- providing a first upright post produced from a first continuous piece of tubular metal by cutting a top portion of the first continuous piece of tubular metal to define a first flange and a second flange such that the first flange and second flange are an integral portion with the first upright post and such that the upright post is formed completely from the first continuous piece of metal, wherein the first flange and the second flange extend entirely along a longitudinal axis of said first continuous piece of tubular metal and define a first area located between the first and second flanges that is configured to receive a portion of the at least one handrail;
- connecting the portion of the at least one handrail to the first upright post between the first flange and the second flange such that the handrail and upright post are pivotally connected at a point located within the longitudinal extent of the first continuous piece of tubular metal, and in a manner that allows the at least one handrail to rotate with respect to the first continuous piece of tubular metal;
- connecting the first upright post to a first side of the support.
A seatainer tread for a gangway comprising:
- a tread support for supporting a user;
- a first upright post comprising a first continuous piece of tubular metal connected to a rear portion of a first side of the tread support, a top portion of the first continuous piece of tubular metal is cut to define a first flange and a second flange such that the first flange and second flange are an integral portion with the first upright post, wherein the first flange and the second flange extend entirely along a longitudinal axis of said first continuous piece of tubular metal such that a first handrail and the first upright post are pivotally connected at a point located within the longitudinal extent of the first continuous piece of tubular metal, and wherein the first flange and the second flange define a first area between the first flange and the second flange that is configured to receive a portion of the first handrail of the gangway;
- a second upright post comprising a second continuous piece of tubular metal connected to a rear portion of a second side of the tread support, wherein a top portion of the second upright post defines a third flange and a fourth flange such that the third flange and fourth flange are an integral portion with the second upright post, wherein the third flange and the fourth flange extend entirely along a longitudinal axis of said second continuous piece of tubular metal such that a second handrail and the second upright post are pivotally connected at a point located within the longitudinal extent of the second continuous piece of tubular metal, and wherein the third flange and the fourth flange define a second area between the third flange and the fourth flange that is configured to receive a portion of the second handrail of the gangway;
- a third upright post connected to a front portion of the first side of the tread support, wherein the third upright post is connected to the first upright post via a first support bar;
- and
- a fourth upright post connected to a front end of the second side of the tread support, wherein the fourth upright post is connected to the second upright post via a second support bar.
3 more elements
A gangway comprising:
- an underbody having a first side and a second side interconnected by a middle section, wherein the first side and second side define relatively parallel planes opposite one another with respect to the middle section;
- a support, wherein a first side of the support is rotatably connected to the first side of the underbody and a second side of the support is rotatably connected to the second side of the underbody;
- an upright post fixedly connected to the first side of the support, wherein the connection of the upright post, the support, and the underbody defines a pivot axis about which the support and the upright post can pivot, wherein the upright post comprises a first continuous piece of metal, a top portion of the first continuous piece of metal defines a first flange and a second flange, wherein the first flange and second flange extend integrally and entirely along a longitudinal axis of said first continuous piece of metal and define a first area located between the first flange and the second flange;
- and
- a handrail connected to the upright post, wherein a portion of the handrail is received within the first area and pivotally connected to the first flange and the second flange at a point located within the longitudinal extent of the first continuous piece of tubular metal.
