Title:
INCLINED LADDER AND SHIP BODY
Document Type and Number:
WIPO Patent Application WO/2019/033619
Kind Code:
A1
Abstract:
An inclined ladder and a ship body, related to the technical field of ships. The inclined ladder comprises ladder side rails (1) and multiple steps (2); the multiple steps (2) are detachably connected between the two ladder side rails (1), and are evenly placed along the lengthwise direction of the ladder side rails (1); each step (2) is provided with multiple through holes (201), and each through hole (201) is provided with an outward folded lip (202) along the hole wall thereof at the side of the step being stepped on. In the inclined ladder, each step is provided with through holes and an outward folded lip is provided at the edge of each through hole, effectively reducing the weight, facilitating water drainage, and enhancing the friction. The outward folded lips provided at the through holes also prevent deformation and contortion caused by stress concentrated at one particular location on the step. By detachably connecting the steps between two ladder side rails, even if a step deforms severely due to service life limit, the step can be changed immediately, and the shape of ladder side rails do not change despite the deformation and contortion of the step, thereby reducing the inclined ladder maintenance difficulty and the necessary maintenance cost.
