Abstract

A davit assembly comprises a leg having an inner portion and an outer portion, a base, a support, and an arm. The inner portion has a first end and a second end, and the outer portion has a third end and a fourth end. The first end and the third end are secured to one another, and the inner portion extends partially along the length of the outer portion. The second end is proximate a middle portion of the outer portion. The base includes a cavity, and the first end and the third end are secured to the base. The bushing is incorporated into the cavity of the base. The support has a bottom end and a top end, the bottom end being rotatable within the bushing and connectable to the base. The arm is operatively connected to the top end of the support.

Claims

1. A davit assembly, comprising:

a) a leg having an inner portion and an outer portion, the inner portion being shorter in length than the outer portion, the inner portion having a first end and a second end, the outer portion having a third end and a fourth end, the first end and the third end being secured to one another, the inner portion extending partially along the length of the outer portion, the second end being proximate a middle portion of the outer portion;

b) a base to which the leg is secured including a cavity, the first end and the third end being secured to the base;

c) a bushing incorporated into the cavity of the base;

d) a support having a bottom end and a top end, the bottom end being rotatable within the bushing and connectable to the base; and

e) an arm operatively connected to the top end of the support.

2. The davit assembly of claim 1, wherein at least three legs are secured to the base.

3. The davit assembly of claim 2, wherein the base includes at least three spokes extending outward from the base, the cavity being between the at least three spokes, the first end and the third end of each leg being secured to each respective spoke and each respective leg extending outward from the base.

4. The davit assembly of claim 1, wherein the second end extends a distance of approximately ½

to ¾

along the length of the outer portion.

5. The davit assembly of claim 1, wherein the bushing is molded into the cavity of the base and is integral with the base.

6. The davit assembly of claim 5, wherein the bushing is made from a material selected from the group consisting of urethane and nylon.

7. The davit assembly of claim 1, wherein the cavity of the base is a bore.

8. A davit assembly, comprising:

a) at least three legs, each leg having an inner portion and an outer portion, the inner portion being shorter in length than the outer portion, the inner portion having a first end and a second end, the outer portion having a third end and a fourth end, the first end and the third end being secured to one another, the inner portion extending partially along the length of the outer portion, the second end being proximate a middle portion of the outer portion;

b) a base including a cavity;

c) at least three spokes extending outward from the base, the cavity being between the at least three spokes, a leg secured to each spoke, the first end and the third end of each leg being secured to each respective spoke, the inner portion and the outer portion of each leg providing additional strength proximate the base;

d) a support having a bottom end and a top end, the bottom end being connectable to the base; and

e) an arm operatively connected to the top end of the support.

9. The davit assembly of claim 8, further comprising a bushing molded into the cavity of the base and being integral with the base.

10. The davit assembly of claim 9, wherein the bushing is made from a material selected from the group consisting of urethane and nylon.

11. The davit assembly of claim 9, wherein the bottom end of the support is rotatable within the bushing.

12. A davit assembly, comprising:

a) at least three legs;

b) a base having a cavity, the at least three legs being connected to the base, the cavity being between the at least three legs;

c) a bushing molded into the cavity of the base and being integral with the base;

d) a support having a bottom end and a top end, the bottom end being connectable to the base; and

e) an arm operatively connected to the top end of the support.

13. The davit assembly of claim 12, wherein the bushing is made from a material selected from the group consisting of urethane and nylon.

14. The davit assembly of claim 12, further comprising a detent within the cavity of the base, the bushing being molded to fill in the detent thereby securing the bushing to the base in the cavity.

15. A method of making a davit assembly, comprising:

a) molding a bushing into a cavity of a base, the bushing being integral with the base;

b) inserting an inner portion into an outer portion, the inner portion having a shorter length than the outer portion, the inner portion having a first end and a second end, the outer portion having a third end and a fourth end;

c) connecting the first end of the inner portion and the third end of the outer portion to the base, the second end of the inner portion extending to proximate a middle portion of the outer portion, the inner portion and the outer portion providing additional strength proximate the base;

d) inserting a support into the cavity, the support being rotatable within the bushing and connectable to the base; and

e) connecting the support to the base.

16. The method of claim 15, further comprising connecting at least three legs to the base.

17. The method of claim 15, wherein the bushing is made from a material selected from the group consisting of urethane and nylon.
