Abstract

A rescue ramp (10) for use by a watercraft (11) includes a laterally extending first inflatable tube member (14) attachable to the watercraft (11). Second spaced inflatable tube members (15) are connected at one end to and extend longitudinally from the ends of the first tube member (14). A third inflatable tube member (16) is connected between the second tube members (15) near the other end thereof and is adapted to be positioned in the water. A ramp (17) is connected to the first and second tube members (14, 15) so that when the rescue ramp (10) is inflated and attached to the watercraft (11), a person may traverse from the water to the watercraft (11) or from the watercraft (11) to the water. The first tube member (14) is attached to the watercraft (11) by means of a girt bar (23) releasably mounted on the watercraft (11). The girt bar (23) is connected to a first flap (26) which is detachably connected to a second flap (20) attached to the first tube member (14).

Claims

1. A rescue ramp for a watercraft comprising a laterally extending first inflatable tube member, means to at least temporarily connect said first tube member to the watercraft, second spaced inflatable tube members having one end fluidly connected to said first tube member and extending generally longitudinally away from said first tube member, a third tube member fluidly connected between and below said second tube members near the other end thereof and adapted to be positioned in the water when said first tube member is connected to the watercraft, and ramp means connected to and between said first and second tube members, said ramp means being the only connection between said first and second tube members at said other end thereof so that a person may readily move onto said ramp means from the water and thereafter may traverse said ramp means from the water to the watercraft or from the watercraft to the water.

2. A rescue ramp according to claim 1 further comprising means to inflate said tube members.

3. A rescue ramp according to claim 2 wherein said means to inflate includes a pressurized canister carried by said first tube member.

4. A rescue ramp according to claim 3 wherein said means to inflate includes a valve positioned in at least one of said second tube members.

5. A rescue ramp according to claim 4 wherein said means to inflate includes an additional valve positioned in said first tube member to pressurize said tube members as necessary.

6. A rescue ramp according to claim 1 wherein said means to connect includes a bar member attachable to the watercraft and means to attach said bar member to said first tube member.

7. A rescue ramp according to claim 6 wherein said means to attach includes a first flap member carrying said bar member and a second flap member attached to said first tube member, said first and second flap members being detachably connectable to each other.

8. A rescue ramp according to claim 1 further comprising first attachment means positioned at said other end of said second tube members and second attachment means positioned on said first tube member, said second tube members being adapted to be folded generally longitudinally in half so that said first attachment means can engage said second attachment means.

9. A rescue ramp according to claim 8 wherein said means to connect includes a flap member generally centrally positioned along said first tube member, said first tube member being adapted to be folded such that it is of a lateral extent approximating the length of said flap member while at the same time positioning said second tube members adjacent to each other.

10. A rescue ramp according to claim 1 further comprising means positioned on said ramp means to assist the person traversing said ramp means.

11. A rescue ramp according to claim 1 wherein said tube members are constructed of a urethane coated nylon woven fabric.

12. A rescue ramp according to claim 1 further comprising life lines mounted on said second tube members on the sides thereof opposite said ramp means.

13. A rescue ramp according to claim 1 further comprising pouch means formed in at least one said second tube member to carry an accessory to assist the person to said ramp means.

14. A rescue ramp according to claim 1 further comprising means to illuminate said ramp means.

15. A rescue ramp according to claim 14 wherein said means to illuminate includes at least one light positioned on each said second tube member and a battery connected to each said light and positioned on said third tube member so as to be in contact with the water.

16. A rescue ramp for a watercraft comprising a laterally extending first inflatable tube member, means to at least temporarily connect said first tube member to the watercraft, second spaced inflatable tube members having one end connected to said first tube member and extending generally longitudinally away from said first tube member, a third tube member connected between said second tube members near the other end thereof and adapted to be positioned in the water when said first tube member is connected to the watercraft, ramp means connected to said first and second tube members, and means positioned on said ramp means including a plurality of hand/foot holds so that a person may be assisted in traversing said ramp means from the water to the watercraft or from the watercraft to the water.

17. A rescue ramp for a watercraft comprising a laterally extending first inflatable tube member, means to at least temporarily connect said first tube member to the watercraft, second spaced inflatable tube members having one end connected to said first tube member and extending generally longitudinally away from said first tube member, a third tube member connected between said second tube members near the other end thereof and adapted to be positioned in the water when said first tube member is connected to the watercraft, ramp means connected to said first and second tube members so that a person may traverse said ramp means from the water to the watercraft or from the watercraft to the water, and means positioned on said second tube members to assist the person to get on said ramp means.

18. A rescue ramp according to claim 17 wherein said means positioned on said second tube members includes a hand-hold mounted on each said second tube member near said other end thereof and above said ramp means.

19. A rescue ramp for a watercraft comprising a laterally extending first inflatable tube member, means to at least temporarily connect said first tube member to the watercraft, second spaced inflatable tube members having one end connected to said first tube member and extending generally longitudinally away from said first tube member, a third tube member connected between said second tube members near the other end thereof and adapted to be positioned in the water when said first tube member is connected to the watercraft, ramp means connected to said first and second tube members so that a person may traverse said ramp means from the water to the watercraft or from the watercraft to the water, and means on said second tube members to attach the rescue ramp to a second watercraft.

20. A rescue ramp according to claim 19 wherein said means on said second tube members includes a D-ring mounted at said other end of each said second tube member.
