Abstract

A handrail for a gangway and a method for manufacturing the same where the handrail comprises a single, continuous piece of plastic.

Claims

1. A gangway comprising:

an underbody support structure;

a first support surface connected to an end of the underbody support structure, wherein a first support surface first upright extends from one side of the first support surface and a first support surface second upright extends from another side of the first support surface;

a second support surface connected to another end of the underbody support structure, wherein a second support surface first upright extends from one side of the second support surface and a second support surface second upright extends from another side of the second support surface;

a left handrail, wherein one end of the left handrail is connected to the first support surface first upright and another end of the left handrail is connected to the second support surface first upright; and

a right handrail, wherein one end of the right handrail is connected to the first support surface second upright and another end of the right handrail is connected to the second support surface second upright, and the right handrail is a first single, continuous piece of plastic.

2. The gangway of claim 1 wherein the left handrail is a second single, continuous piece of plastic.

3. The gangway of claim 1 wherein the right handrail is manufactured via a rotational molding process.

4. The gangway of claim 2 wherein the left handrail is manufactured via a rotational molding process.

5. A handrail for a gangway comprising a single, continuous piece of plastic comprising:

an elongated, generally cylindrical main body portion; and

a first tab extending from the elongated, generally cylindrical main body portion, wherein the first tab is adapted to be received by a first portion of the gangway and defines a first aperture through which a first connecting mechanism is passed in order to connect the handrail to the gangway.

6. The handrail of claim 5 wherein the connecting mechanism is a rod.

7. The handrail of claim 5 wherein the elongated, generally cylindrical main body portion defines a flat area at one end of the elongated, generally cylindrical main body portion and a half spherical area at another end of the elongated, generally cylindrical main body portion.

8. The handrail of claim 5 wherein the single, continuous piece of plastic further comprises an elongated, generally cylindrical secondary body portion positioned relatively parallel to the elongated, generally cylindrical main body portion with respect to an axis of the elongated, generally cylindrical main body portion, wherein the elongated, generally cylindrical secondary body portion exhibits a first diameter less than a second diameter of the elongated, generally cylindrical main body portion, the elongated, generally cylindrical secondary body portion exhibits a first length less than a second length of the elongated, generally cylindrical main body portion, and the elongated, generally cylindrical secondary body portion is connected to the elongated, generally cylindrical main body portion.

9. The handrail of claim 5 wherein the single, continuous piece of plastic further comprises a second tab extending from the elongated, generally cylindrical main body portion, wherein the first tab is adapted to be received by a second portion of the gangway and defines a second aperture through which a second connecting mechanism is passed in order to connect the handrail to the gangway.
