Aquatic ladder for marine applications
View Patent ↗The aquatic ladder has wide, deep treads, arranged like a staircase, with side and upper railings to make it easy to enter or exit the water, even by elderly people, tired individuals, those carrying aquatic equipment, such as SCUBA gear or water skis, and, even, by pets. The ladder is preferably made from aluminum, although it can be made of other materials, such as steel (e.g., stainless or galvanized), fiberglass, plastic, or other composites.
1. An aquatic ladder, comprising:
a. a pair of sloped and substantially parallel step support members, said step support members each comprising a front support member and a rear support member, said front support member being spaced from said rear support member, wherein said front support members and said rear support members each includes upper and lower ends, the upper end of each rear support member having a bent portion which connects to the upper end of the respective one of said front support members of each of said step support members, said front support members and said rear support members each further separated into upper and lower portions at an intermediate location between said upper and lower ends;
b. a pair of handrails, each of said pair of handrails having an inverted, substantially U-shape with forward and rear portions, each of said forward portions being attached to said front and rear support members;
c. a pair of hinges attached at said intermediate location of each said front support member pivotally connecting each of said upper portions of said front support members to a respective one of said lower portions of said front support members; and
d. a plurality of relatively deep and relatively wide substantially horizontal steps being mounted to said sloped support members, said horizontal steps each having front and rear ends, wherein said front support members are attached to the front ends of each said horizontal steps and said rear support members are attached to the rear ends of said horizontal steps, and wherein each lower step of said horizontal steps is displaced both vertically and horizontally further from a location where one of said horizontal steps immediately above it is attached to said step support members.
2. The aquatic ladder of claim 1 wherein said front members are formed of tubular material.
3. The aquatic ladder of claim 1 wherein said front members are formed of a material selected from the group consisting of aluminum, stainless steel, galvanized steel, fiberglass, plastic, and composites.
4. The aquatic ladder of claim 1 wherein said handrails comprise attachment means for attaching said ladder to a dock, a floating platform, or a boat.
5. The aquatic ladder of claim 1 wherein further comprising standoff means for attaching said ladder to a dock, a floating platform, or a boat.
6. The aquatic ladder of claim 5 wherein said standoff means are particularly adapted for attaching said ladder to a pontoon of a pontoon boat.
7. The aquatic ladder of claim 1 further comprising standoff means for attaching said handrails, said standoff means comprising at least one horizontal portion attaching said standoff means to said support members whereby said handrails can have spacings which differ from said support members.
