The present invention relates, in its broader aspects, to Hooring, in general. More s ecilically, this invention has particular re ation to that type of ooring commonly known as parquet flooring or parquetry.
Among the objects of the present invention are: to provide a novel and improved unitv of parquet flooring; to rovide simple, novel and improved means or holding'the several l0. component strips Aof each unit securely together; to provide a novel, eiicient and inexpensive fastener for firmly securing a numer of the parquetry units in place on an j under-floor without exposing the'fastener or 15. piecing or leaving unsightly nail-holes in the parquetry; and to provide a parquetry unit and coacting fastener of the character abovedescribed which shall/.be especially adapted to be used in connection with concrete floors. To the accomplishment of these objects and such others as may hereinafter appear, the various features of the present invention relate to certain devices, combinations, and arrangements of parts fully set forth herein- 25 after, the advantages of which will be readily understood by those skilled in the art to which this invention pertains.
The various features of the invention will be best understood from an inspection of the 60 accompanying sheets of drawings illustrating the preferred forms of the invention.
1n the said drawings, Fig. 1 is a top plan view of a unit of parquetry embodying the present invention, and 35 a broken top planview of an adjacent unit;
Fig. 2 is a perspective view, illustrating the manner in which the fastener of the present invention cooperates with the parquetry units;
4o rig. 81S a partial end. 'View of one of the parquetry units looking inthe direction of.
arrow A in Fig. 1; v
Fig. 4 isa top plan view of the strip-securing device;
Fig. 5 is a sectional view taken along line 5-5 of Fig. 4; and Fig. 6 is a view similar to Fig. 5, but illustrating a modified form of the invention.
' Similar reference numerals refer to similar 5a parts throughout the several views.
According to the present invention, each unit of parquetry, indicated in general at 10 (in Fig. 1), may comprise a plurality of strips 11, l2, 13 and 14 of suitable and preferably relatively' thin high-'grade wood. The.
strips are illustrated in the drawings as being of such length and width as to form a square unit of parquetry when assembled. However, it is obvious that the number and dimensions of the strips may be varied to suit different tastes and for different purposes.
In order to enable the several strips 11, 12,
13 and 14 to be securely fastened together v to form a unit of parquetry, they are providedv ,with a suitable number of transversely-extending spaced grooves 15 of a suitable depth, as hereinafter explained in greater detail.
The number of such groovesmployed will obviously depend on the shape and size of the unit of oorin Relatively thin metallic strips 16, havingy saw-tooth edges 17 and tonguelike ends 17', are adapted to'be disposed in the grooves 15 with the teeth ofthe edges 17 biting into the adjacent strips 11, 12, 13 and 14. In this way the several strips are effectively bound together as a unit to successfully resist lforces acting thereon in any direction and tending to displace them relative to each other.
` versely bent; as is shown in dotted lines in Fig.` 3, so that its effective original width is equal to that lof its cooperating groove 15. By hammering or otherwise exerting a pressure on the face of the strip 16 in the direction of the arrow B (Fig. 3), the strip is lattened out and its saw-toothed edges are driven into biting relation with the adjacent wooden strips, as shown.
The edges of each unit 10 ofparquetry are severally milled to provide them with tongue-receiving grooves 18 extending substantially the full length ofeach edge. Each unit 10 1s also rabbetedto form grooves 19 around the bottom thereof. Grooves 19 are preferably made about one and a half times as wide as grooves 18, as shown. These grooves 18 and 19, in effect, form tongues 20 between them. The ends of tongues 20 are cut short so. that they do not extend clear out to the edges of the parquetry units for a purpose which will hereinafter appear.
Fasteners are provided for securely binding the units of parquetry to the sub-flooring and to each other. These fasteners are preferably bent from sheet metal to the form clearly shown in Figs. 2 and 5. They preferably comprise horizontal two-ply tongues 21 adapted to be snugly received in the grooves 18 of the parquetry units, and base or supporting portions 22 extending laterally from one side of the bottom of vertical portions 23.
The vertical portions 23 are adapted to be received between the shortened tongues 20, as is clearly shown in Fig. 5, and the bases 22 are substantially coextensive with and adapted to be received in the rabbeted grooves 19.
The base portions 22 extend only from one side of the vertical members 23, and with the corresponding tongues 21 form sockets adapted to receive the tongues 20 of adjacent parquetry units.
Nails, or other suitable fastening elements, may be driven directly into the under-Booring through the base portions 22. The tongues 21, vertical portions 23 and bases 22 are continuous and longitudinally coextensive with each other and with the edges of the units 10, as shown in Fig. 1. In this manner a firm support is provided which ex" tends along the'entire length of each unit of parquetry. p
The grooves 15 extend upwardly to the bottom of grooves 18. The tongues 17 of the fasteners 16 extend into the lgrooves 18 to take the place of those portions of tongues 20 which are removed in the ormation of grooves 15. In this way, asubstantially continuous support is afforded to the corresponding tongue 21.
In laying the ioor, the under-flooring is iirst covered with a layer of mastic or the like. Then a unit of parquetry is laid thereon. A fastener tongue is inserted into the groove 18 of each exposededge of the unit so that the base portions extend outwardly. Nails or the like are then driveninto the concrete sub-flooring through the base portions. Then another unit of parquetry 10 withv its component strips 11, 12, 13 and 14 disposed transversely to the strips of the first unit, is
laid in'place. The groove 18 of the second,
unit receives the exposed tongue of the fastener, the base portion 22 fitting into the rabbet 19.
entire flooring is laid.
In Fig..6, a modification of the invention is shown. f This modification difers from the hereinbefo're described embodiment only in' of the contiguous fastener.
.'Ifhis process is continued until the` ias Base portions 22 et the fasteners are preferably provided with a plurality of )l-shaped. cut-outs 24 between the several nail-holes 25. In case the under-flooring is o' a character with which nails may not be used, the X- shaped cut-outs 24C are adapted to receive mastic and securely hold the fasteners down on the mastic-covered under-ooring.
lt is obvious that the fastener above described is adapted to be used in the laying of strip ooring on concrete underooring as well as with parquet ooring, and also in the attachment of panels to walls.
l. In combination, a unit of parquetry comprising a plurality of strips of ooring material, a second unit of parquetry comprising` a plurality of strips of ooring material, said last-named strips extending in a direction transversely to said rst-named strips, each of said units having a groove extending therearound, a one-piece sheet metal fastening device disposed between said units and comprising a base portion, a vertical portion disposed at one side of said base portion, and a pair of tongues, one of said tongues being disposed in the groove of one of said units, and the other of said tongues being disposed in the groove of the other unit, each of said tongues, base portion and vertical portion being continuous and longitudinally coextensive.
2. A one-piece sheet metal fastening device .adapted to be used with flooring comprising a base portion, a vertical portion extending upwardly from said base portion at one side thereof, and a pair of tongues extending outwardly from the top of said vertical position, said base portion, vertical portion and tongues being longitudinally coextensive and continuous.
3. A one-piece sheet metal fastening clip ofthe character described comprising a base,
a vertical member extending from one edge of said base substantially at right angles thereto, said clip being bent laterally from the top of said vertical member in the direction in which base extends to form the lower ply of a tongue, said ply bent bent back upon itself to form the upper ply of the said tongue and the upper ply of a second and oppositely-extending tongue, the free end of said lastnamed ply being bent back upon itself to form the lower ply of said second tongue.A
