Abstract: A safety system for a swimming pool ladder is described for use in above-ground swimming pools. The safety system can comprise a frame covered with fabric or other enclosure permanently or temporarily affixed to the ladder and/or the sidewall of an above-ground swimming pool. The fabric can comprise a plurality of vent holes to prevent excessive side loads caused by water currents. The safety system can be detachably coupled to the ladder using a tab and slot configuration. The safety system can prevent objects from entering and becoming trapped between the pool sidewall and the pool ladder.

Abstract: Aspects of the present disclosure relate to a safety mechanical barrier for use with a ladder for an above-ground swimming pool that is easy to install and provides safety from children accessing the pool via the ladder. Certain aspects of the present disclosure relate to a safety mechanical barrier that blocks access to the ladder itself, thereby restricting access to an above-ground pool by unsupervised minors.

Abstract: The present invention is directed to ladder sculptures and methods of use, and in particular to anthropomorphized ladder sculptures. The ladder structure has a first ladder leg with a portion having a shape generally depicting a profile of a human male or human female body an a second ladder leg with a portion having a shape of a human male or human female body. A plurality of rungs interconnect the first and second ladder legs, with the portions depicting the human female or male body shape positioned between top and bottom ends of the ladder legs.

Abstract: A ladder is disclosed including wheels normally received off the ground, and four legs normally supporting the ladder. When it is desired to move the ladder, it is pivoted off the legs until the wheels contact the ground and fully support the ladder. The ladder may then be moved. A rail includes an angled portion which provides a handle allowing the ladder to be easily moved. The wheel is most preferably mounted above the ground by a distance between its radius and its diameter such that when the ladder is supported on the wheels, the legs will not interfere with the ground.
Abstract translation: 公开了一种梯子，包括通常从地面接收的轮子，以及通常支撑梯子的四条腿。 当需要移动梯子时，它从腿部枢转，直到车轮接触地面并完全支撑梯子。 梯子然后可以移动。 轨道包括倾斜部分，其提供允许梯子容易移动的手柄。 车轮最优选地安装在地面上方的半径与其直径之间的距离，使得当梯子被支撑在车轮上时，腿不会干扰地面。

Abstract: The folding step ladder has lower and upper treads and lower and upper risers which are pivotal relative to the treads. The ladder also has front and back side panels on each side of the treads. The side panels on each side are pivotal relative to each other. The lower riser is pivotal relative to the lower tread and to both of the front side panels. A rear panel is pivotal relative to both of the back side panels and the upper tread. When the step ladder is closed or folded and one of its components is lifted, gravity causes the step ladder to open or to unfold. When another of its components is lifted while the step ladder is open or unfolded, gravity causes the step ladder to close or to fold. Handles are provided on the two components to facilitate lifting of them.
Abstract translation: 折叠阶梯具有下胎面和上胎面以及相对于胎面枢转的下和上立管。 梯子还在胎面的每一侧都有前后面板。 每侧的侧板相对于彼此是枢转的。 下立管相对于下胎面和两侧面板都是枢转的。 后面板相对于后侧面板和上胎面都是枢转的。 当阶梯被关闭或折叠并且其部件中的一个被提起时，重力使梯子打开或展开。 当梯子打开或展开时，当其他部件被抬起时，重力会使梯梯关闭或折叠。 在两个部件上提供手柄以方便提起它们。
