SWIMMING POOL SK-IMMING GUTTER Filed May 17. 1968 United States Patent C) m 3,546,719 SWIMMING POOL SKIMMING GUTTER Kenneth M. Bishop, 310 Market St., Carlisle, Iowa 50047 Filed May 17, 1968, Ser. No. 729,996 Int. Cl. E0411 3/16 US. Cl. 4172.17 9 Claims ABSTRACT OF THE DISCLOSURE A device for controlling the flow of water from a swimming pool into the skimming gutter including an inner gutter wall adjustable in height and an apertured bafile plate extending diagonally inwardly and downwardly across the gutter forming two compartments in the gutter. The splashing waves against the apertured plate are divided into those passing through the plate into a first compartment and those being deflected down wardly into a second compartment in the skimming gutter. The diagonally disposed plate is integral with a top deck plate and has its lower end received in the outer gutter vertex formed by the outer and bottom gutter walls and thus strengthens the top deck plate. The baffle plate may have holes decreasing in size from top to bottom such that the splashing water passing through the top holes will be metered from the first compartment into the second compartment through the bottom holes.

This invention is particularly concerned with two problems common in conventional swimming pools. First, for efficient skimming action of the pool water to occur the water level must be just slightly above the gutter so that a thin film of water passes into the gutter thereby minimizing the amount of water circulated through the filtering system and additionally providing the most effective skimming action for removal of dust, leaves and other matter at the top surface of the water before it settles beneath the water surface. Changing the level of the pool water requires either adding or removing a substantial amount of water and thus is not easily accomplished. The adjustable cap on the inner wall of the gutter makes it simple to obtain the exact desired skimming action by controlling the flow of water into the gutter from the pool.

The second common problem with conventional swimming pools is that turbulent splashing water in the pool is often an undesirable condition. This is particularly true when competitive speed swimming meets are being conducted. The water hitting the side walls and skimming gutters of the pool is deflected directly back into the pool and against swimmers approaching the waves of water thereby significantly reducing their swimming speed. These waves are typically established by the lead swimmers and work to the detriment of the trailing swimmers. The dampening baflle plate extending across the skimming gutters captures some of the splashing water and deflects other water downwardly into the gutter and thus minimizes the water that is deflected back into the pool thereby reducing water turbulence in the pool. The water passing through the baffle plate is metered down into the skimming gutter while the water hitting the diagonally disposed baflle plate is deflected downwardly rather than straight back into the pool.

Another advantage of this novel gutter structure is that it is simple to manufacture and strong in construction since the gutter is formed in a shape of a channel and the baffle plate includes a top plate portion which functions as a part of the swimming deck and is detachably connected to the outer wall of the channel-shaped gutter by bolts or the like. The lower edge of the baflle plate is received in the vertex of the channel outer and bottom walls and thus is mechanically locked in place to strengthen the top deck plate.

These and other features and advantages of this invention will become readily apparent to those skilled in the art upon reference to the following description when taken into consideration with the accompanying drawings, wherein:

FIG. 1 is a perspective View of a swimming pool employing the skimming gutter structure of this invention;

FIG. 2 is a cross sectional view taken along line 22 in FIG. 1;

FIG. 3 is a front elevation view of the structure illustrated in FIG. 2 but illustrating an alternate embodiment of the adjustment bolt for the cap;

FIG. 4 is a view similar to FIG. 2 but showing an alternate bafiie plate construction and also showing the cap on the gutter wall adjusted to a lower position from that shown in FIG. 2;

FIG. 5 is a fragmentary view of an alternate embodiment of the height adjusting bolt structure for the skimming gutter; and

FIG. 6 is a cross sectional view similar to FIG. 5 but showing a third cap adjustment bolt assembly.

The swimming pool of this invention is referred to generally in FIG. 1 by the reference numeral 10 and includes metal wall sections 12 having abutting side flanges 14 interconnected by bolts 16. In FIGS. 2 and 4 the pool is shown filled with water 18. A concrete deck 22 extends around the perimeter of the pool.

The pool 10 includes a novel skimming gutter 24 being channel-shaped in cross section and having inner and outer

upstanding walls

26 and 28 integral with a bottom wall 30. A horizontally extending flange 32 extends inwardly over the top flange 34 of the pool walls 12. The gutter flange 32 is fastened to the wall flange 34 by bolts 36.

The outer gutter or trough wall 28 extends higher than the inner wall 26 and extends to the top ofi the deck 22 where it is fastened by bolts 38 to a downwardly extending flange 40 integrally connected to a horizontally disposed deck plate 42 also integrally connected to a baflfle plate 44 which includes a downwardly extending portion 46 merging into a diagonally inwardly and downwardly extending portion 48 terminating in the vertex 50 of the bottom and

outer trough walls

30 and 38 respectively. The diagonally extending bafile plate portion 48 includes apertures 52 decreasing in size from top to bottom in FIG. 3 and uniform in size in FIGS. 2 and 4. These apertures may be of any desired size or shape to receive splashing water 54 from the pool water 18 as seen in FIGS. 2 and 4.

It is seen in FIGS. 2 and 4 that the splashing water 54 passes over the pool wall and hits the diagonally disposed baflle plate portion 48 with a portion 54A of the water passing through the baflle plate portion 48 into a compartment 56 while other water 54B is deflected downwardly into the bottom of the trough of the gutter. The water 58 in the bottom of the skimming trough will then flow to an outlet drain (not shown) for circulation through the filtering system and return to the pool.

It is seen that the water 54A caught in the compartment 56 falls to the bottom thereof and is metered through the lower openings 52 in the battle plate portion 48 whereby it is returned to the bottom of the gutter trough.

The skimming gutter is easily constructed of two sheets of metal material as seen in FIGS. 2 and 4 and may be quickly assembled or disassembled by use of the bolts 38. The mechanical locking of the lower edge of the baffle plate 48 in the bottom outer vertex of the channel-shaped trough eliminates the need for any welding but yet provides substantial structural strength with a minimum quantity of materials.

In FIG. 4 an alternate baffle plate construction is shown wherein the baffle plate 44A includes a single straight diagonally disposed baffle plate portion 48A extending from the inner edge of the top deck plate 56. The structure is otherwise the same as that shown and described in FIG. '2.

The skimming action of the gutter structure is varied by an adjustable in height channel-shaped cap 60 extending downwardly over the pool walls. The inner leg 62 of the cap 60 matingly engages the pool wall 12 while the outer leg 64 matingly engages the inner trough channel wall 26. A bolt 66 extends through the gutter and

pool wall flanges

32 and 34 respectively and includes a head 68 for engaging the base or top wall 70 of the cap 60. A nut 74 is welded to the bottom side of the pool wall flange 34 and thus permits height adjustment of the bolt 66 as seen in FIGS. 2 and 4 where the cap 60 is in its raised position and then lowered to its lowered position. In the embodiment of FIGS. 2 and 3 the height of the cap 60 is varied by removing the cap 60 and adjusting the bolt 66 accordingly. The cap 60 then is returned.

In FIG. an alternate cap unit 60A is illustrated wherein the adjustment may be made without removing the cap. A bolt 66A has a flat head 68A exposed from the exterior of the cap 60A for adjustment by a screwdriver or the like. The top wall portion 70 of the cap 60A rests on a nut 80 secured by weld 82 to the bolt shank. The bolt shank then extends into a nut 74 welded on the lower surface of the pool wall flange 34. Thus adjustment of the bolt 66A will cause the cap 60A to be lowered and raised as desired.

A third alternate cap adjusting bolt 60B is shown in FIG. 6. The heads of the bolts 36B interconnecting the gutter flange 32 to the pool wall flange 34 are tapped to threadedly receive an adjustment bolt 66B. The flat head 68B and nut 80B are similar to the structure of FIG. 5. This arrangement does not disturb the seal held by the bolts 36 between the gutter and the pool walls.

It is to be appreciated that through the use of either of the

caps

60, 60A or 60B in units of FIGS. 2, and 4, 3 and 5 that the edge of the pool around its perimeter may be maintained in a level condition by appropriate adjustment of selected

bolts

66, 66A or 66B. It is further seen that the height of the pool edge may be varied to change the amount of splashing that occurs and thereby alter the amount of water being exposed to the dampening action of the gutter 24 and the

bafile plate

48 or 48A.
