COMBINATION SWHVIMING POOL, SKATING RINK AND EXHIBITION FLOOR Ralph N. Skrainka, Ladue, Mo. Application May 27, 1953, Serial No. 357,829 3 Claims. (Cl. 272-3) The present invention relates generally to masonry and concrete structures,

and, more particularly, to a 'as either a swimming pool, a skating ring or an exhibition floor.

It is an object of the provide a novel structure the remaining portions by barriers so either as a skating rink or an exhibition floor.

Another object is to provide a novel structure having barriers, water, and then freezing the same.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein a preferred embodiment of the present invention is shown, in which:

Fig. 1 is a top plan view of a structure embodying the teachings of the present invention;

Fig. 2 is a vertical longitudinal sectional view of the structure;

Fig. 3 is an enlarged vertical transverse sectional view taken on the line 33 in Fig. 1;

Fig. 4 is a perspective view of the structure showing the activities area prepared for use as a swimming pool; and

Fig. 5 is a perspective view of the structure showing nited States Patent 0 ing from one side 2,766,046 Patented Oct. 9, 1956 and includes side roughly semicircular in shape. The floor segment 23 of the central section 24 may be covered with asphalt, macadam or the like, or may be finished with cement in the conventional manner.

As shown in Fig. 2, ection 24 i ,wall 22.

A series of spaced openings 32 are contained in the floor between the segments 21 and 23, and, hence, between the deep end section 26 and the central section 24, similar openings 34 are contained in the top of the wall 30, both of said series for a purpose to be described hereinafter.

5), and openings 38 to accommodate the end posts and guide wires for a tennis net 40 (Fig. 5).

A fiat concrete apron 42 extends around the periphery Removable barriers 56 and 58 (Fig. 5), which contain supporting means for holding engagement with the open ings 32 and 34, respectively, are provided to be erected at the ends of the central section 24, as will be more fully described hereinafter.

The tiered seating areas 14 are shown and it is to be understood that they may be provided with locker rooms, may be constructed under novel structure which for.

of illustration and example,

position, and the barriers 56 and 58 erected over the openings 32 and34, respectively.

It is to be understood that the central section can also be used for basket ball games, and the like, by removing the net 40, installing 'a'reinovable wood flooring '(not shown), and using removable type basket supports (also not shown).

Also, it is manifest that it canb'e used for prizen nts, wrestling'm'atche's, and the-like, byerec'tingta -removable ring" in the center of the central s ection and installing temporary seats around it.

To use the structure as a skating rink (Fig. '3), the barriers 56 an'dSS areferected, the'fioor of the central section cleared, refrigeration pipesffi fl laid ther'eongthe central section flooded with a relatively thin layer'of water, and the latter "frozen by pumping refrigerant through the pipes 60, The lower portion of the barrier 56 'isisubsta'ntially waterproofand the lower edge thereof 'forms a substantially water tight-seal with the bottom-wall ofthe central sectio '24"so that practically no water escapes from'the centrals'ection during the" ice forming period. Any water which might -es'c apernerely flows into the deep end section and into the drain-53. The resilient members 50 permit the ice to expand when forming without injuring the side walls 16, 18 and 30.

Thus, it is apparent that there has beenprovided a fulfills all the objects sought therelt is to be understood that the'foregoing description and the accompanying drawings have been given only byway and that changes and alterations in the present disclosure, which will be readily apparent to one skilled in the-art,-are contemplated as within the scope of the present invention which is 'limited only by the claims which follow.

'What is claimed 1s: e

1. A structure which can be used as'a swimming pool, skating rink or exhibition 'fioor; comprising an elongated waterproof enclosure having a side wall and a bottom wall, the central portion of said enclosure being of roughly rectangular shape, and the end portions of roughly semicircular shape, the upper surface of the bottom wall of the central portion being substantially level, the bottom wall of one end section sloping downwardly away from the central portion, and the bottom wall of the other end section sloping upwardly away from the central portion, said level surface containing markings for a tennis court or the like; means for supporting the posts for a tennis net or the like; removable for isolating the latter from the end portions-ybarriers at the'ends 'of'the 'central'portion; and seats overlooking the enclosure.

2. An arena for a variety of specialized athletic contests and exhibitions; said arena comprising an elongated activities area circumvented'by a continuous wall-,'a floor for said activities area, said floor being below the upper level of said wallfsaid floor including an intermediate portion having a substantially fiat horizontal surface and end portions having surfaces at levels respectively above and below the level of said fiat horizontal surface, and a waterproof barrier wall removably disposed at the junction of thei'ntermediate floor portion and the e'ndfio'or portion having its surface below the level of the intermediateportion,said barrier wall being adapted to cooperatewiththe aforementioned continuous wall in retaining manager] said intermediate floor portion.

'3. 'Tl'ie'a'rena of claim 2 wherein those portions of the continuous wall which adjointheintermediate floor portion are provided with resilient members adapted to'yield in response to exertion of lateral pressure thereagainst' as a resultof the freezing-of water retained upon thefioor portion.
