Abstract

A swim platform assembly is for a boat and comprises a deck which is pivotable relative to the boat into and between a raised position and a lowered position, wherein in the lowered position the deck extends transversely relative to a sidewall of the boat and provides a platform surface on which a swimmer can stand; and a suspension linkage configured to suspend the deck from the boat, the suspension linkage comprising a pivot bracket which defines an inner pivot axis about which the deck is pivotable into and between the raised and lowered positions.

Claims (38)

1 . A swim platform assembly for a boat, the swim platform assembly comprising:

a deck configured to pivot relative to the boat into and between a raised position and a lowered position, wherein in the lowered position the deck is configured to extend transversely relative to a sidewall of the boat and provides a platform surface on which a swimmer can stand; and

a suspension linkage configured to suspend the deck from the boat, the suspension linkage including a pivot bracket that defines a pivot axis about which the deck is pivotable into and between the raised position and the lowered position and a suspension arm that couples the deck to the pivot bracket;

wherein the deck is suspended from the pivot bracket via the suspension arm, and

wherein the pivot axis is located above the deck and the suspension arm extends through the deck at least when the deck is in the lowered position.

2 . The swim platform assembly according to claim 1 , further comprising an actuator configured to pivot the deck into and between the raised position and the lowered position.

3 . The swim platform assembly according to claim 2 , wherein the actuator includes a linear actuator having an inner end configured to be pivotably coupled to the sidewall of the boat and an outer end pivotably coupled to the deck.

4 . A swim platform assembly for a boat, the swim platform assembly comprising:

a deck; and

a suspension linkage configured to pivotably suspend the deck from a sidewall of the boat, the suspension linkage defining a pivot axis about which the deck is pivotable relative to the boat into and between a raised position and a lowered position in which the deck provides an upper surface on which a swimmer can stand, wherein the pivot axis is above the deck in the lowered position and the suspension linkage extends through the deck at least when the deck is in the lowered position.

5 . The swim platform assembly according to claim 4 , wherein the suspension linkage extends through a slot extending into an outer edge of the deck when the deck is in the lowered position and wherein the suspension linkage moves out of the slot when the suspension linkage is moved out of the lowered position.

6 . The swim platform assembly according to claim 5 , wherein the suspension linkage is fixedly coupled to a lower surface of the deck.

7 . The swim platform assembly according to claim 4 , further comprising an actuator configured to pivot the deck at least into the raised position.

8 . The swim platform assembly according to claim 7 , wherein the actuator is a linear actuator having an upper end pivotably coupled to the deck and a lower end configured to pivotably couple to the sidewall of the boat.

9 . The swim platform assembly according to claim 8 , wherein the upper end of the linear actuator is pivotably coupled to a lower surface of the deck.

10 . The swim platform assembly according to claim 8 , wherein the lower end of the linear actuator is configured to pivotably couple to the sidewall of the boat below the deck.

11 . The swim platform assembly according to claim 4 , wherein the suspension linkage includes a pivot bracket configured for fixed attachment to the sidewall of the boat and a suspension arm that pivotably suspends the deck from the pivot bracket along the pivot axis.

12 . The swim platform assembly according to claim 11 , wherein the suspension arm is fixedly coupled to the deck.

13 . The swim platform assembly according to claim 11 , wherein the suspension arm is fixedly coupled to a lower surface of the deck.

14 . The swim platform assembly according to claim 11 , further comprising a base bracket configured for fixed attachment to the sidewall of the boat, the base bracket being configured to mate with and support the deck when the deck is pivoted into the lowered position.

15 . The swim platform assembly according to claim 4 , further comprising a base bracket configured for fixed attachment to the sidewall of the boat, the base bracket being configured to mate with and then support the deck as the deck is pivoted into the lowered position.

16 . The swim platform assembly according to claim 15 , further comprising a linear actuator configured to pivot the deck at least into the raised position, the linear actuator having an upper end pivotably coupled to the deck and a lower end configured to pivotably couple to the sidewall of the boat below the base bracket, wherein extension of the linear actuator pivots the deck into the raised position and retraction of the linear actuator pivots the deck into the lowered position.

17 . A boat comprising the swim platform assembly according to claim 4 .

18 . A boat comprising:

a deck; and

a suspension linkage configured to pivotably suspend the deck from a sidewall of the boat, the suspension linkage defining a pivot axis about which the deck is pivotable relative to the boat into and between a raised position and a lowered position in which the deck provides an upper surface on which a swimmer can stand, wherein the pivot axis is above the deck in the lowered position; and

a linear actuator configured to pivot the deck at least into the raised position, the linear actuator having an upper end pivotably coupled to the deck and a lower end pivotably coupled to the sidewall of the boat.

19 . The boat according to claim 18 , wherein the suspension linkage includes a pivot bracket fixedly coupled to the sidewall of the boat and a suspension arm that pivotably suspends the deck from the pivot bracket along the pivot axis.

20 . The boat according to claim 18 , further comprising a base bracket fixedly coupled to the sidewall of the boat, the base bracket being configured to mate with and support the deck in the lowered position.

21 . The boat according to claim 18 , wherein the upper end of the linear actuator is pivotably coupled to the deck and the lower end of the linear actuator is pivotably coupled to the sidewall of the boat below the deck.

22 . A swim platform assembly for a boat, the swim platform assembly comprising:

a base bracket configured for fixed attachment relative to the boat;

a deck that is pivotably coupled to the base bracket along a first pivot axis so the deck is pivotable about the first pivot axis into and between a raised position and a lowered position, wherein in the lowered position the deck provides an upper surface for supporting a swimmer; and

a pivot linkage configured to support the deck in the raised position and in the lowered position, the pivot linkage including a first arm extending between an upper portion pivotably coupled to the deck and a lower portion, and a second arm extending between an inner portion pivotably coupled to the base bracket and an outer portion pivotably coupled to the lower portion of the first arm,

wherein pivoting the deck into the raised position causes the pivot linkage to engage a first stop on the base bracket to support the deck in the raised position and pivoting the deck into the lowered position causes the pivot linkage to engage a second stop on the base bracket to support the deck in the lowered position.

23 . The swim platform assembly according to claim 22 , configured so a weight of the deck biases the pivot linkage against the first stop as the deck is pivoted towards the raised position and so the weight of the deck biases the pivot linkage against the second stop as the deck is pivoted towards the lowered position.

24 . The swim platform assembly according to claim 22 , wherein pivoting the deck into the raised position causes the second arm to engage the first stop and the second stop.

25 . The swim platform assembly according to claim 22 , wherein the first stop and the second stop are provided by cutouts formed in the base bracket.
