April 5, 1949. R. M. RICHARDSON PORTABLE KNOCKDOWN FLOOR CONSTRUCTION Filed Dec. 18, 1945 W lll lllll Inventor a jakardsan Rag ' I I, torneys Patented Apr. 5, 1949 UNITED :iS RA- l'iE'N l rem-Ant naemewweo'on CONSTRUCTION -3 Claims.

1 This invention relates to portable *fio'or cen- "struction of a knoc-ledown type and has refe'rence in" particular to an especially rnadeup assemblage which is especially, but' not necessarily, adapted t'o "fun'ctionasa 'dancefloor, or, preferably, as a iloor for -askating rink. I

As above "setforth, and although-the former the invention adopted is "susceptible-in serving in many *capacities, "the "structural airrangement heri'n shown and described-isexpressly intended toxs'er've as a skating rink in that-itcan be-set"-up, *taken' down, or rep'aired and 'mad'e' practicable for use in varioustype's of louil'dirigs'and'inclosures, "as" well as utilized out-of-do'o'rs wherever-necessa'r'y or desired.

"In" carrying; out the principles of the preferred embodiment of the*inven'tion, the floor pro'p'eris characterized by hardwood tongue "and groove "stock, "the individual sections being relatively "short "pieces and theseof standardized 'and pre- "deteririine'd'dimensions soastdfitand' nestprop- "'erly together and "so "as "to "ihake "for rea-dy and satisfactory "repairs whenever ene "or more seetior'is' become damaged or require replacement.

Anotherobject and feature of the invention has to do with the adoption "and use or longitu- "iiinal edging members for the "opposite longitu- "structure, these being in the form "of "angle irons said irons serving "not 'om'y'as 're-inforci'iig cornice pieces but as eeeemmeasudn means irer 'assenibling rods ems 'for rails or 'fnces used as running guards on either one or fboth sides of the coinple'ted's'tructure. Armenia in carrying "out another phase ofjthe invention, I provide a sectional knockdown floor in which the tongue andgroove sections or-piecesare not only standardized in dimensions f or "interchangeability and quick repairs but are provided -Wi-th transverse bores, --these "being :parallel to each other and located at specific points so that the bores of the respective sections aiidf'ajltof said sections can be lined up to accommodate the transverse assembling and retaining rods or bolts.

Other objects, features and advantages will become more readily apparent from the following description of the accompanying illustrative drawings.

In the drawings, wherein like numerals are cdrdarice with the principlesiof the presentin- 2 ventiony-on'e -of the sections being remo'ved to r'riak'e' 1 my for arep'air. c Figure -2 is"'an p'erspective view o'f {one of tiie standardized tongue -and groove sections.

Figure 3 is an enlarged fragmentary detail seet'i'on #t'a'ken -011 the approximate plane of 'the'line 33 3 of Figure 1, and

:Figure 1 *is a "fr'a'gfnentary el'evatiorfal showing tlie manner -in which' the' knock I fence is setup for use on the flooras"a niargina1 guid'e.

:As hefor'e stated :the entire as'sembly is Zo'f e portable knockdown type, the-floor properb'eii fg 'denoted by the .-numera1 "Ei and bemeer sectional -construction and-in fact made: up of the tong-tie and *groove 'sectionsorpie'cs shown, "one being I "illustrated" in*Figure 2 -and denoted by the mer'al "1. In other words, the entire =floor' G- is made up of standardize'd' tongue and groove'sto'ck -i,:-the tongue being indicated at 8 'andthe groove -at9. The aforementioned bores are denoted li'y the numerals ID.

In "connection with the foregoing it understo'od that ertainpiec'es on the ends, that-is, the opposite ends of the "completed floor =may be made "sh'orter or longer than the regular or 'boil iy pieeestl, such as for exam le the pieces lla't the'left in Figure 1. This is necessary-mower te permit the overall structure to fit in certain f-liinited or-fixed areas, but in the main e11 of the pieces"wil1 be of the-size and proportiton 'asshooin inFigure 2. The obvious purpose of this isthat zit proposes expeditious manufacturing anaes- "seinbling and disassembling. Also, if one of "the pieces in ithe middle of the floor, for example,

'ibe'comes damaged so that it interferes with-"a. v

smooth surface, I the repla'cement of this can irea'dily accomplished. This'isattainalbl e ih't all; Ft-he Various pi'e'ces 'l'are assembled and-seen 3. together by longr o'cl s or so-called bolts HZ. Th sfe --a-re identical and arranged at "equally spaced points throughout the "longitudinal dimension bf evident in "nuts J4, the latter 'seryiri'g to hear 'aj'ga st ftrudeithrough and loeyondthe lbngitaainai eases 3 of the made up floor and carry springs and the springs serve as compensating elements for expansion and contraction and general cushioning purposes.

As before indicated I provide corner shields and re-inforcing members for the longitudinal edges of the completed floor structure. These shields are in the form of angle irons and are denoted by the numerals H. The angle iron is the same on each side of the floor structure as seen in Figure 1. The vertical flanges l8 are apertured to permit I The horizontal flanges l9 rest on the top of the endmost floor sections 7. On one side I desire to use a knockdown fence or guard 20 as shown in Figure 4. This is made up of vertical posts 2| and horizontal rails 22 properly connected together by suitable unions or couplings. The lower ends of the posts are threaded and are fitted into sockets 23, the sockets being fastened to the top flange I9 on the underlying angle iron 11. Thus the flange 19 on one side serves as a mount for the socket 23 which in turn serves to support the hand rail.

By removing one of the sections 1 as shown at point 24 of Figure 1 another section, of a corresponding side can be readily inserted. This pro vides for the aforementioned quick repair result.

,, What I claim is:

1. A knockdown type portable floor expressly adapted and suitable for use in a skating rink comprising a sectional floor embodying a plurality of duplicate tongue-and-groove boards arranged in end-to-end abutting relationship and side-byside interfitting relationship, said boards being relatively short in relation to the overall length of the finished floor and the boards of one row being in break-joint relation to the boards of the next adjacent row, each board having a pair of transversely located bolt-accommodating holes situated inwardly of the opposite end portions of said board, all of said bolt holes being grouped and lined up in relative order and relationship and thus providing passages extending transversely across the entire floor, and a plurality of bolts fitting in the respective passages and serving to clamp the floor boards together in abutting relationship, the opposite ends of the respective bolts being screw-threaded, assembling and clamping nuts on the respective screw-threaded ends, a pair of lengthwise extending floor-reinforcing and protecting angle irons, said angle irons being disposed along the opposite outer longitudinal edge portions of the complete floor, having their horizontal flanges resting upon the top surfaces of the boards of the outermost rows, having their vertical flanges resting in contact with the outer marginal edge portions of said outermost boards, the threaded ends of said bolts yextending through and beyond bolt holes pro- -vided therefor in the coacting vertical flanges.

2. A knockdown type portable floor adapted for use in a skating rink comprising a sectional floor embodying a plurality of duplicate tongue-- and-groove boards arranged in abutting end-to- =end relationship and side-by-side interfltting relationship, said boards being relatively short in relation to the overall length of the finished -fioor and the boards of one row being in breakholes being lined up'in relative relationship and thus providing a plurality of parallel passages ex- 1 upon the top surfaces of the boards of the two outermost rows, having their vertical flanges resting in contact with the outer marginal edge portions of the boards of said outermost rows, the threaded ends of said bolts extending through and beyond bolt holes provided in the coacting vertical flanges, and a vertical fence of a length commensurate with the length of the floor and situated along one longitudinal edge portion of the floor, said fence embodying vertical posts connected together by horizontal hand rails, the lower ends of said posts being anchored on the horizontal flange of the coacting angle iron.

3. A portable and knockdown floor comprising a floor constructed from tongue-and-groove boards, substantially all of said boards being relatively short in their relation to the total length of the complete floor and all of said boards being of the same dimensions so that they are interchangeable and so that they may be removed and replaced for ready repair purposes, all of said boards being arranged in end-to-end row relationship, the boards of the respective and adjacent rows being staggered in relation to each other to provide break-joint relationship of the boards of adjacent rows, each floor board having transverse bolt holes, coacting bolt holes of associated floor boards being lined up to provide bolt passages extending transversely across the entire floor, a pair of angle irons situated along opposite longitudinal edge portions of the floor, the horizontal flanges of the respective angle irons resting atop the surfaces of the floor boards in the outermost rows of the finished floor, the vertical flanges resting in contact with the vertical marginal edges of said outermost boards, and a REFERENCES CITED The following references are of record in the file of this patent:
