摘要： A self-retracting step assembly is attached to a swimming platform provided on the rear of the hull of a boat. The self-retracting step assembly includes a ladder comprising a series of telescoping tubes which enable its extension and retraction. The step assembly including the ladder assembly are attached to the swimming platform in a position in which the ladder is capable of extending into the water wherein the watercraft or boat floats. The telescoping ladder assembly can be extended and placed from a normally horizontal position into an inclined position wherein at least the last step of the ladder reaches the water. The energy for extending the ladder is supplied by a human user. The step assembly includes a motor or mechanical means for storing the energy used for extending the ladder. The ladder assembly is locked into the extended and inclined position by an improved mechanism that is located within the assembly attached to the swimming platform. Retraction of the ladder assembly is triggered by a change in the angle of the ladder relative to the water, said change being triggered by force of the water relative to the ladder when the watercraft or boat moves. The energy utilized for the retraction is preferably the stored energy of the extension, or it can be supplied by a motor.
摘要翻译：自动回缩步骤组件附接到设置在船体后部的游泳平台。自动回缩步骤组件包括梯子，其包括一系列伸缩管，其能够延伸和缩回。包括梯子组件的步骤组件在梯子能够延伸到水中的位置处附接到游泳平台，其中船只或船浮动。伸缩式梯子组件可以从正常水平位置延伸并放置到倾斜位置，其中至少梯子的最后一步到达水面。用于延伸梯子的能量由人类用户提供。台阶组件包括用于存储用于延伸梯子的能量的马达或机械装置。梯子组件通过改进的机构锁定在延伸和倾斜的位置，该机构位于附接到游泳平台的组件内。梯子组件的缩回是由梯子相对于水的角度的变化触发的，当船只或艇移动时，所述变化由水相对于梯子的力引起。用于回缩的能量优选地是延伸部的储存能量，或者可以由电动机供应。
