This invention relates to a new and) improved stile and, particularly, to a cantilever stile for use in entering and leaving, plastic swimming 12 .018. of he yp h rein. the wall. thereof projects upwardly from, a bottom portion resting on the ground.

It is a particular object of the present invention to provide a newand improved cantilever stile for use with plastic swimming pools.

It is a further object of the invention to provide such a device wherein one of the ladder structures of the stile, is positioned above the bottom portion of the pool to substantially eliminate puncturing of the bottom of the pool through use of the stile.

A further object is to provide such a device that is light in weight, sturdy in construction, and relatively in expensive to construct. v

A further object is to provide such a device that is portable in nature and may be removed to. prevent uninvited admittance to the pool by young children.

These and other objects and advantages of the present invention are provided by a cantilevered stile comprising a pair of vertically spaced A-frames, plural horizontal tread members supported between opposed leg members of said A-frames to provide a pair of ladder structures, anchor means at the lower end of one of said ladder structures to maintain the lower end of the other of said ladder structures in cantilevered suspension.

The invention will be more particularly described with reference to the illustrative embodiments thereof wherem:

Fig. 4 is a fragmentary view of a further form of anchor means for the stile;

Fig. 5 is a fragmentary plan view of still a further form of anchor means; and

Fig. 6 is a section substantially on line 66 of Fig. 5.

. Referring to the drawings and, in particular, to Figs.

1 and 2, the improved cantilever stile generally comprises a pair of A-frames ltl and 12. The A-frame 10 includes a pair of

stringer members

14 and 16 interconnected at their upper ends by a spacer member 18 while A-frame member 12 includes an identical pair of stringer members 14 and 16' interconnected adjacent their upper ends by a spacer member 18'.

i The pair of stringer members 14 and 14' have secured thereto a plurality of horizontal tread portions designated 20 while the

stringer members

16 and 16 have secured therebetween a plurality of tread members 22.

Positioned between the

upper spacer members

18 and 18 is a platform generally designated 24 which may comprise a plurality of spaced planks 26 which form the platform between the

ladderstructures

28 and 30, and as a safety feature, paired

handrail members

32 and 34 may be provided to project upwardly from the platform. The handrails areiconuected by screw or bolt means to'the 2,962,112 Patented, Nov. 29, 1 960,

extended ends of the spacer members 18111116 18' as more clearly shown in Figs. 1 and 2 OfthedraWings.

Referring particularly to Fig. 2, it will be. seen thatthe stringer

members

16 and 16" are of a lesser length than stringer members 14- and 14' whereby the ladder structure 30' formed bythe stringer members 16 and 16' and the horizontal tread members 22 is maintained in suspension above the ground level. Inorderto provide a stable stile and to preve-ntthe stile from sinking into the ground, a baseboard 36 i s-secured to the lower ends of stringer members: 14 and 14" and anchor means are provided for the ladder structure 28. The anchor meansfor thecanti'levered stile shown in Figs. 1 and 2 gen erally comprises a pair of

anchorstakes

38 and 38" having sharpened or wedge-shaped lower ends. The

anchorstakes

38 and 38 are driven into the ground or where desired placed in eoncrete'or the like so that; the upper face 40 of the ane-hor stakes are substantially at ground level. Into each of the upper faces 40 f the

anchor stakes

38 and 38 is secured an eye-bolt or screw Cooperating anchor hooks 44 are secured to the stringer members 14 and 14- by screw eyes 46 so positioned that the hook portion of the anchor hooks engage the eyes 42 received in the upper ends of the

anchor stakes

38 and 38 to releasably secure the ladder structure 28- into snug engagement with the ground.

ice

In order to take the reactions of he load on the cantie levered stile,

vertical posts

48 and 48" may extend from the ground to the apex of the ladder structures. The posts 48 and; 48'" are secured to their respective space;

members

18 and 18;""at the upper end of the stile and where desired, the lower ends of the post members lil' and 48" may also be provided with a base portions!) and diagonal sway braces 52 and 5.4. Horizontal'brace meme;

bers

56 and 58, extending between the

posts

48 and 48 and stringers 14 and 14', respectively, may also be added to the structure.

The cantilevered stile of the invention is illustrated in Figs. 1 and 2 in combination with a plastic swimming pool designated 60 having a bottom portion 62, a side wall 64 and support means 66 for the side wall. With a swimming pool having a side wall projecting about 30 or 36 inches above the ground, a cantilevered stile having the following dimensions has been found tq be very satisg factory:

Height of stile 3' 6'" Another form of anchor means for the, cantilevered stile of the invention is illustrated in Fig. 3. In Fig. 3, a pair of footings 80, one for: each of the

A-frames

10 and 12, is positioned under the bottom portion 62 of the pool and so positioned that a portion of the footings pro? ject outwardly of the wall 64 of the pool 6.0. The pro-. jecting portions 82 of the footings 8.0 are below ground level (indicated at 84) and have secured thereabout metal sleeves 86. The post portions. 48, and .48 and their

corresponding stringer members

14, and 14 are intercom nected by further footing members 88 with the footing members 88 projecting beyond the post members 4.8. and 48 toward the wall 64 of the, pool. The projecting po t 0 of ch o the ot n s 8.8. are received in the metal sleeves 86 of their respective permanent? fggting members anchored under the pqolbottorn 62 A pair?- of thumb pins 92 are received in bores in the sleeves 8

ing members

80 and 88 to releasably secure the

footing members

80 and 88 within the sleeves 86. With this form of construction by removing the four thumb pins 92, the footings 88 maybe withdrawnjfrom the sleeves, 86 and the cantileveredstilel moved to a position remote from the swimming pool to prevent access to the water in the pool by small children.

Referring to. Fig. 4, a further form of anchor meansfor the cantilevered stile is shown. In Fig. 4, a pair of stakes 100 is anchored in the ground and each of the anchor stakes 100 hassecured to the top thereof a cross arm 102by, for example, screw means 104. The cross arms 102 each are provided with a projecting boss portion 106 which boss portion is positioned above the ground a distance equal to the thickness of the footing blocks 36 secured to the lower ends of the

stringer members

14 and 14 forming the ladder structure 28. In this form of the invention, the projecting portions of the footing member 36 are slid under the projecting portion of the anchor blocks or cross arms 102 whereby the stile is effectively and releasably anchored to the ground external of the wall portion 64 of the swimming pool.

A further form of anchor means is illustrated in Figs. and 6 wherein the footing 36' secured to the stringer members 14 and 14' of the ladder structure 28 is provided with a pair of openings 107. Positioned vertically below the openings 107 in the footing member 36' is an anchor stake 108. Each of the anchor stakes 108 has secured therein an eye screw generally designated 110 with the eye portion thereof projecting above the opening 107 in the footing member 362. To install the cantilevered stile provided with the anchor means shown in Figs. 5 and 6, the stile is positioned above the anchor stakes 108 with the eye screws 110 projecting through the openings 107 in the footing member 36'. With the stile thus positioned, pin means 112 is slipped through each of the eyes of the eye screws 110 securely and releasably anchoring the ladder structure 28 to the ground. Each of the pins 112 may be provided with chain means 114 secured as at 116 to the footing member 36' to prevent loss thereof when the novel cantilevered stile is not 11] use.

The cantilevered stile of the present invention may be constructed of conventional construction materials, such as wood, metal; or plastic or combinations of metal, plastic or wood as desired. It will be further appreciated that constructional details of the cantilevered stile will be varied, depending upon the particular construction material and it will be appreciated that where the cantilevered stile is to be used with a portable plastic swimming pool, it would be desirable to releasably secure the tread portions 20 and 22' to their

respective stringers

14, 14', 16 and 16; the

base parts

50 and 36 to said stringers; the platform 26 to spacers 18 and 18' along with the

horizontal braces

52 and 54 and the diagonal sway braces 52-52.

The foregoing would leave the two A frames assembled to their respective stringers, 14-14' 16-16, spacers 18, 18'

horizontal brace members

56, 58 diagonal sway braces 52--54 handrails 32-34, and posts 4848'. This would provide a minimum bulk of ladder parts for packaging in a carton or tied bundle by the manufacturers for wholesalers, retailers and ultimate consumers or users storage and provide a knocked-down stile that can be easily assembled by the user by graphic and written instructions and if necessary partially dismantled by the user for storage during the non-swimming season.
