SAFETY LADDER FOR ABOVE-GROUND SWIMMING POOL
Abstract
An improved ladder assembly is provided for the aboveground type
of swimming pool. The ladder of the invention may be bolted to the
top edge of the side of the swimming pool, and the section of the
ladder outside of the pool is pivotally mounted so that it may be
swung up off the ground for safety reasons, and to prevent
unattended children, for example, from climbing up the ladder and
falling into the pool.

Claims
What we claim is:
1. In combination with the top edge of the side of an aboveground
swimming pool:
a pair of side brackets affixed to said top edge and extending
thereacross in spaced relationship to one another;
a ladder section having a pair of side rails pivotally coupled to
respective ones of said side brackets and normally extending down
from the top edge of the side of the pool externally of said side,
and a plurality of spaced transverse steps affixed to said rails
and extending therebetween;
said brackets pivotally coupling said ladder section to said top
edge of said pool to support said ladder section against the side
of the pool and to permit said ladder section to be swung up to an
inaccessible position, at least insofar as small children are
concerned, the portion of said top edge of said side between said
brackets forming a seat deck for the ladder.
2. The combination defined in claim 1, and which includes a pair of
upstanding inverted U-shaped handles affixed to respective ones of
said side brackets.
3. The combination defined in claim l, and which includes an inner
ladder section attached to said bracket means and extending down
from the top edge of the side of said pool internally of said
side.
4. The combination defined in claim 3, in which said inner ladder
section has side rails integral with respective ones of said
handles.
Description
BACKGROUND OF THE INVENTION
The usual prior art ladder assembly for use with aboveground
swimming pools usually includes an inner section which has steps
extending down into the water in the pool; and it also includes an
outer section which has side rails resting on the ground, and which
includes steps to enable one to climb up over the side and into the
pool. However, the prior art type of ladder is a potential hazard
to children, since they may climb up into the pool when they are
not appropriately supervised.
The ladder assembly of the present invention, however, by the
simple expedient described above, completely removes the hazard,
and it provides a simple and expeditious means for rendering the
pool absolutely safe, insofar as small children are concerned.
BRIEF DESCRIPTION OF THE DRAWING
FIG. l is an external view of an aboveground swimming pool, and
showing the external part of the ladder assembly constructed in
accordance with one embodiment of the invention, and with the
ladder assembly in position for normal usage;
FIG. 2 is an external view of the aboveground swimming pool of FIG.
l, and showing the external section of the ladder assembly of FIG.
l swung up into a safe position, so as to prevent use by unattended
children; and
FIG. 3 is a top perspective view showing the upper portion of the
ladder assembly, and the manner in which the ladder assembly is
secured to the top edge of the pool.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
The ladder assembly illustrated in the drawing includes an external
section having a pair of side rails 10 and 12 which extend down
from the top 14 of the side 16 of the swimming pool, when the outer
section is in its normal position, and to the ground, as shown in
FIG. l. The side rails 10 and 12 include a plurality of transverse
steps 20 extending therebetween. The outer section of the ladder
assembly is supported on the top of the side of the pool by means
of a pair of side brackets 24 and 26 which are bolted or otherwise
secured to the pool, as shown, for example, in FIGS. 2 and 3.
A pair of handles, each having an inverted U-shaped configuration,
are secured to the side brackets, these handles being designated 30
and 32. The ladder assembly also includes an inner section which
extends down into the pool, and whose side rails, for example, may
be integral with the inner portions of the handles.
As shown in FIGS. 1--3, the upper ends of the side rails 10 and 12
of the external section of the ladder assembly are pivotally
secured to the brackets 24 and 26 by means, for example, of bolts
34 and 36. This permits the outer section to be swung up from the
position shown in FIG. l, to the position shown in FIG. 2, when the
pool is not in use, and for the reasons described above.
As best shown in FIG. 3, for example, the top edge 14 of the pool
may form a deck seat for the pool ladder to add to the convenience
of the assembly.
The invention provides, therefore, an improved safety ladder
assembly for use with aboveground swimming pools, and which
provides a simple and foolproof means, whereby the pool may be
rendered safe from unauthorized use by small children, small
animals, or the like.
