Abstract
Abstract A pool ladder for use by individuals confined to a wheelchair having a top step which is at a height substantially equal to the height of a wheelchair seat, and a second step which is at a height slightly above the wheelchair foot rests. Both the top step and the second step are moveably connected to the ladder so as to allow them to be moved aside during standard use. A series of support members serve a dual purpose by supporting the steps of the ladder and also providing handgrips for one entering or exiting the pool.

Claim 1
Independent Claim
126 words
A pool ladder to facilitate the downward movement of an individual from a wheelchair which is positioned on a plane surface, such as a pool deck, into a pool comprising: means for supporting a plurality of steps in the form of a flight of stairs running downwardly from a top step into the pool, the top step being at a position accessible from a wheelchair on the deck; a top step connected to the support means, said top step positioned to be accessible from a wheelchair on the deck and at a height above the deck approximately equal to the height of a wheelchair seat; and a plurality of steps which, together with the top step, form a flight of stairs running downwardly into the pool.
Claim 2
Dependent Claim
126 words
A pool ladder to facilitate the downward movement of an individual from a wheelchair which is positioned on a plane surface, such as a pool deck, into a pool comprising: means for supporting a plurality of steps in the form of a flight of stairs running downwardly from a top step into the pool, the top step being at a position accessible from a wheelchair on the deck; a top step connected to the support means, said top step positioned to be accessible from a wheelchair on the deck and at a height above the deck approximately equal to the height of a wheelchair seat; and a plurality of steps which, together with the top step, form a flight of stairs running downwardly into the pool.
Claim 3
Dependent Claim
72 words
The invention of claim 1 wherein the supporting means further comprises at least two siderails secured to the plane surface and extending into the pool, said siderails being secured in a spaced apart relationship so as to allow for the movement of the wheelchair therebetween, and wherein the top step and the plurality of steps forming the flight of stairs are connected to the siderails so as to span the space therebetween.
Claim 4
Dependent Claim
33 words
The invention of claim 2 wherein the top step is moveably connected to the siderails such that it can be moved aside so as to no longer span the space between the siderails.
Claim 5
Dependent Claim
39 words
The invention of claims 1, 2 or 3 wherein a second step next follows the top step, said second step being at a height above the plane so as to allow for the movement of the wheelchair's footrests thereunder.
Claim 6
Dependent Claim
33 words
The invention of claim 4 wherein the second step is moveable connected to the siderails such that it can be moved aside so as to no longer span the space between the siderails.
Claim 7
Dependent Claim
18 words
The invention of claim 5 wherein the top step is between 14 to 18 inches above the plane.
Claim 8
Dependent Claim
17 words
The invention of claim 5 wherein the second step is at least four inches above the plane.
Claim 9
Dependent Claim
50 words
The invention of claim 1, 2 or 3 wherein the siderails further comprise: a vertical portion which is secured to the plane and rises substantially perpendicular thereto; and a descending portion which slopes in a downward and outward direction from the uppermost part of the vertical portion into the pool.
Claim 10
Dependent Claim
45 words
The invention of claim 8 wherein the siderails further comprise: a first series of support members each of which is attached to the vertical portion and extends substantially perpendicular thereto until they reach the descending portion of the siderail to which they are also connected.
Claim 11
Dependent Claim
14 words
The invention of claim 9 wherein the steps are connected to the support members.
Claim 12
Dependent Claim
42 words
The invention of claim 10 wherein a portion of each support member is not covered by its associated step so that said uncovered portion can serve as a hand grip which enables the user to lower himself to the next succeeding step.
Claim 13
Dependent Claim
16 words
The invention of claim 11 wherein said hand grip portion is covered by a non-slip material.
Claim 14
Dependent Claim
48 words
The invention of claim 12 further comprising: a backing means to close the space between the steps so as to prevent a user's body from entering therebetween; and means for blocking the underside of the ladder so that swimmers will be prevented from surfacing from beneath the steps.
