Description

BACKGROUND

A boat lift for small watercraft such as kayaks and canoes utilizes an elongated plastic cradle to receive the watercraft thereon. However, a drawback with such a structure is that the elongated plastic cradle is relatively heavy and difficult to move during installation. Further, the elongated plastic cradle may degrade over time when exposed to intense sunlight.

The inventor herein has recognized a need for an improved boat lift assembly that minimizes and/or reduces the above-mentioned problems.

A boat lift assembly, comprising: a first base member having a central beam portion, a first sloped beam portion, and a second sloped beam portion that define a flat vertical outer surface that extends an entire longitudinal length of the first base member; the central beam portion of the first base member being coupled to and between the first sloped beam portion and the second sloped beam portion of the first base member; the first sloped beam portion of the first base member being tilted downwardly with respect to the central beam portion of the first base member; the second sloped beam portion of the first base member being tilted downwardly with respect to the central beam portion of the first base member;a second base member having a central beam portion, a first sloped beam portion, and a second sloped beam portion that define a flat vertical outer surface that extends an entire longitudinal length of the second base member; the flat vertical outer surface of the second base member extending parallel to and facing the flat vertical outer surface of the first base member, the central beam portion of the second base member being coupled to and between the first sloped beam portion and the second sloped beam portion of the second base member; the first sloped beam portion of the second base member being tilted downwardly with respect to the central beam portion of the second base member; the second sloped beam portion of the second base member being tilted downwardly with respect to the central beam portion of the second base member;a first v-shaped roller tube being coupled to and between a portion of the flat vertical outer surface defined by the first sloped beam portion of the first base member and a portion of the flat vertical outer surface defined by the first sloped beam portion of the second base member;first and second rollers being rotatably disposed on the first v-shaped roller tube;a second v-shaped roller tube being coupled to and between a portion of the flat vertical outer surface defined by the central beam portion of the first base member and a portion of the flat vertical outer surface defined by the central beam portion of the second base member;third and fourth rollers being rotatably disposed on the second v-shaped roller tube;a third v-shaped roller tube being coupled to and between a portion of the flat vertical outer surface defined by the second sloped beam portion of the first base member and a portion of the flat vertical outer surface defined by the second sloped beam portion of the second base member; andfifth and sixth rollers being rotatably disposed on the third v-shaped roller tube.

13. The boat lift assembly of claim 12, wherein: the first v-shaped roller tube having a first roller tube portion and a second roller tube portion coupled together;the first roller tube portion extending through the first roller, the first roller being rotatable relative to the first roller tube portion; andthe second roller tube portion extending through the second roller, the second roller being rotatable relative to the second roller tube portion.

14. The boat lift assembly of claim 13, wherein: the first roller tube portion of the first v-shaped roller tube being coupled to the first sloped beam portion of the first base member; andthe second roller tube portion of the first v-shaped roller tube being coupled to the first sloped beam portion of the second base member.

15. The boat lift assembly of claim 12, wherein: the central beam portion, the first sloped beam portion, and the second sloped beam portion of the first base member being longitudinally aligned with one another;the central beam portion, the first sloped beam portion, and the second sloped beam portion of the second base member being longitudinally aligned with one another; andthe second base member extending parallel to the first base member.

16. The boat lift assembly of claim 12, wherein: the first base member is a first aluminum base member; andthe second base member is a second aluminum base member.
