BOAT FRAME WITH INFLATABLE BOTTOM AND SIDE BALLOONS Russian patent published in 2021 - IPC B63B3/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and is intended for use mainly in conditions of movement both on water and on land. The frame of a boat with an inflatable bottom and side balloons contains external protective sheets made of polyethylene, formed in the form of a bottom, which has a continuation upward by bends to a part of the circumference of the inflated side inflatable balloons of the boat, and attracted to the sides of the inflatable boat due to the fastening of their ends to the side longitudinal beams the frame, which, together with the bends of the protective sheets on a part of the circumference of the inflated side inflatable balloons of the boat and its beams connecting its side longitudinal beams, forms grips that elastically clamp the fully inflated side inflatable balloons. The frame beams interconnect the longitudinal side beams of the frame and are rectilinear and located in horizontal planes, and the continuation upward by the bends of the outer protective sheets is made with outward deflection so that at the junction with the side longitudinal beams they form an acute angle with the horizontal plane.

EFFECT: simplification of the structure and its assembly, as well as improved usability of the frame of the boat frame with an inflatable bottom.
