PORTABLE, REVERSHBLE DANCE FLOOR Herbert B. Mueller, Los Angeles, Calif.
Application March 6, 1953, Serial No. 340,791
2 Claims. (Cl. 20-6) This invention relates to portable reversible dance ooring, and more particularly to a portable dance flooring provided with improved means for maintaining its connected parts dependably in place in the laid or operable position.
yIt is an object of the present invention to improve upon the portable dance floors which form the subject matter of Patents No. 2,019,692, and No. 2,102,086, respectively issued to me November 5, 1936, and December 14, 1937.
In said patented oor structures each floor section consists of boards or narrow strips which have to be secured together 'in the manufacture of the door, and although they form a good floor, yet not so desirable a floor as that provided by the present invention.
My invention relates to a dual-surface interlocking portable oor, its principal use is to provide a decorative and practical resilient door for dancing in the home.
The principal object of my invention is to facilitate a quick change of the surface design or pattern in a sectional movable dance oor, by the use of either surface or a combination of alternate surfaces in joining the sections together in the desired pattern.
Another object of my invention is to laminate a diler-` ent design and/ or colors on opposite sides of a section of lvlasonite or similar sheet material, and to provide a means for securely joining the sections together by turning a locking device from either side -of a section.
A further object of my invention is to prevent the aforementioned floor from moving when laid over Woven carpeting, by anchoring the same -to the Warp in the carpet.
Dancing upon the portable, laid floor will cause it'to creep in relation to the underlying carpet unless it is securely anchored to the latter.
A still further object of the present invention is to improve upon oors constructed of wood lby providing novel plastic and steel structures to stilen and strengthen the floor and to prevent its edge portions from breaking.
In carrying out the objects of the present invention square oor panels or sections are provided, which are securable to each other with their edges abutting in a floor forming assembly.
Other objects, advantages and features of invention will p hereinafter appear.
Referring to the accompanying drawing, which illustrates a preferred embodiment of the invention,
Fig. 1 is a fragmentary plan view of a dance oor constructed in accordance with my invention, upper portions of the oor being broken away in four places so as to show structure that would be hidden. In this view six oor panels are completely shown, together with fragments of associated panels.
Fig. 2 is an enlarged, fragmentary vertical section yon line 2 2 of Fig. 1.
Fig. 3 is an enlarged, fragmentary, horizontal section illustrating one of the locking devices. Line 3--3 of Fig. 4 indicates the plane of section.
rates Patent 'wie Fig. 4 is 'a fragmentary vertical section on line 4 4 of Fig. 1.
Fig. 5 is a perspective view of one of the flanged clips which are used to prevent lateral displacement of the tl-oor panels or sections.
Fig. 6 is a fragmentary sectional view of one of th panels illustrating the tongue and groove portions thereof.
Referring in detail to the drawing, this improved port-r able floor is therein shown as comprising an assembly of inner square panels 10 and outer square floor panel-s 11, these panels all being constructed in substantially the same way, but dilferent reference characters being applied to the outer panels from the inner ones for convenience in description.
By preference and as shown, each of these panelsconsists of a middle lamina 15, an upper plastic lamina 16, and a lower plastic lamina 17. Sai-d middle lamina is preferably made of a tempered plastic, such as Mas-onite, and said upper Iand lower lamina are preferably made of Vinol or other, firm durable plastic substance having a smooth, hard outer finish.
In the laid floorsaid panel-s Iabut each other in an edgewise manner, there being a tongue and groove lit between the abutting panels as best illustrated in Figs. l and 6. Said tongues and grooves occupy `only about the central third of the width ofthe middle lamina, the tongues being formed by gluing, or otherwise securing, metal stri-ps into the aforesaid grooves where desired.
In order to secure to each other the adjacent panels of the laid oor, tool operable, swingable hooks 25 cooperate with vertical pins 26. Each of said hooks is provided with a tool socket 27 located at the axis about which the hook swings. These hooks need not be further described since they are substantially the same as the hooks used for a similar purpose described in my aforesaid Patent No. 2,102,086.
In order to provide a clear operating `space for each of said hooks 25 (each hook 'being located in an edge portion of a panel), the edge portion of the middle lamina 15 of the hook carrying panel is provided with `a semicircular recess 30 and the adjacent panel edge is likewise provided with an opposed recess 31 formed by cutting away through somewhat more than a semicircle the edge portion of the middle Ilamina 15 of the adjacent tongue carrying panel. Each said pin 26, as shown in Fig. 4, cxtends through all three laminae of the panel which carries it, and each swingable hook 25 likewise has its bea-rings partly in the upper and lower lamina of the panel in which itis mounted.
Two types of anchor plates or clips are provided to hold the laid floor against creeping or lateral shifting, All of the panels (both 10 and 11), are held in part, inwardly spaced from their margins, by small anchor plates 35 which underlie the panels in the laid floor, pin-s 36 upstanding from said plates 35 and projecting upwardly into the panels. Each of said anchor plates is suitably perforated to receive a plurality of small pointed pins 37 which `are so short that they do` not rea-ch the floor 39 which underlies the carpet 40, a Isuitable thin pad 41 being interposed between said carpet and oor. Said ycarpet is shown comprising a nap 40a which is sufficiently compressible to allow the thin anchor plates to embed themselves therein when the assembled panels are superimposed upon them.
Marginal anchor plates or clips 45 are also provided for the laid oor each of these plates having a Hat, rectangular body portion 46 and lacross one end an upstanding channel forming flange or hook portion 47. The channel or open side of the hook portion is directed toward the 'body portion of the plate and completely spans the edge portion of the portable oor. These anchor plates have through their body portions a plurality of small kapertures 4`8` to receive pins 49' like the aforesaid pins 37 and dimensioned to extend downwardly to the same extent.
Preparatory to putting the floor forming panels in place, straight marks may be made on the carpet indicating where the edges ofthe laid panel assembly will be located, Iand' said marks thenY be used as guides for putting the oor in place. Clips 47 are place-d under the edge of the `Hoor after it has been laid, only on the sides in which direction the nap leans. Also plates 35 need not be placed in all sections,` but are only used where needed to keep the oor from creeping. As the workman proceeds to put the various panels in place he will slip the pins 36 of the interior anchor plates' through suitable perforations that have been provided forrthem in said panels, the anchor pins 37 having been previously projected into' said plates 35 in afriction tight manner withV their point portions projecting as shown.
As the layingfof the floor proceeds the tongues 21 will be inserted into the grooves 20 with which they co-operate, and the lhooks 25 (initially coniined to the semicircular recesses 30), will be swung by the use of a suitable tool into interlocking relation to the pins 26, thus securely locking together the adjacent panels ofthe laid 25 panels being square, one or more of them may be removed from' the laid' and replaced after being given one or more quarter turns.
I claim:
1. The combination, with a portable laid oor, of angular clips having elongated horizontal 'body portions and upstanding from end portions of said body portions hook portions abutted internally by and completely spanning marginal porti-ons of said floor, and pins extending through said body portions into an underlying carpet, said pins terminating superjacent to the oor upon which the carpet rests, so that the floor under the carpet is unmarred by said pins.
2. The combination, with a portable laid floor, a carpet upon which said door is superimposed, and a permanent floor underlying said carpet; of horizontal anchor plates between `said oor and carpet, and fastening means securing said plates both to said portable floor and to said carpet, said fastening' means having point portions terminating superjacent to the permanent floor.
