tables, living room tables and recreation room tables. While such tables may be constructed in numerous shapes and designs, and may be equipped with either folding legs or permanently fixed legs, they are generally characterized by an edging frame made from selected finished hard- Woods which provide an attractive edging border for the table top. The covering sheet is stretched over the center section of the table top and extends to a decorative spline set into the finished face of the edging frame to provide a trim and attractive border for the periphery of the stretched covering. Covering sheets for table tops are made of various materials which may be selectively employed, such as natural leathers, artificially simulated leathers, coated fabrics and various resinous or plastic sheetings of the required toughness and wearability.

It has been common practice to secure the peripheral edge portion of the covering sheet to the edging frame by cutting a groove in the edging frame, then inserting the peripheral edge portion of the covering sheet into the groove, and then closing the mouth of the groove by a trimming spline made from a suitable hard plastic material which is wedged into the groove in a manner intended to lock the peripheral edge portion of the covering sheet therein. The covering sheet, the trimming spline, and the finished surface of the edging frame may be made in selected colors to emphasize artistic color contrasts, color harmonies, and color variations which are particularly appealing and restful to the eyes of the user.

A serious drawback in covered table tops as presently constructed arises from the difficulty encountered in securely and permanently locking the peripheral edge portion of the covering sheet in the groove of the edging frame so that the peripheral edge portion will not become loosened from the groove during use, or for reasons of rough handling, or as a result of temperature or humidity changes. This difficulty of adequately locking the peripheral edge portion of the covering sheet in the receiving groove becomes even more seriously acute when plastic sheetings are used as the covering material, since plastic covering sheets commonly used have a tendency to slip and creep. While the trimming spline as formed from hard plastic material adequately serves to close the groove and additionally provides a trimmed edge for the sheet covering, it has heretofore been expected that the trimming spline would also serve as a wedging element to wedge the peripheral edge portion of the covering sheet in the margin forming groove. Such plastic trimming splines, while providing a satisfactory decorative trim for the marginal edge of the covering sheet, have been found to be inadequate to permanently lock the peripheral edge portion of the covering sheet in the receiving groove, with the result that the sheet covering often loosens from the table top, causing wrinkling of the center section thereof in a manner to materially detract from the intended finished appearance of the table top.

In accordance with this invention, improved means are provided for securely and permanently locking the peripheral edge portion of the covering sheet within the receiving groove formed in the table top edging frame so that the covering sheet will maintain its taut and stretched appearance, with the trimming spline permanently and immovably locked in the receiving groove, thereby overcoming the serious drawbacks to covered table tops as heretofore constructed. The improved locking means comprises a rattan strip inserted into the groove in a manner to bind and lock the peripheral edge portion of the covering sheet firmly and permanently in the groove.

The rattan strip is initially substantially circular in cross section, and has a diameter closely approaching the width of the groove. As the normally round rattan strip is pressure driven into the groove by the pressure roller, the rattan strip is pressure shaped into generally rectangular form, with the side faces thereof flattened against the groove inserted inner and outer side sections of the covering sheet, which are thereby correspondingly pressed against the roughened inner and outer vertical faces of the groove. The bottom face of the rattan strip is thus flattened, will also flatten out the bottom section of the covering sheet against the fiat bottom face of the groove and firmly wedge the corners of the covering sheet into the bottom corners of the groove. The flattened rattan strip frictionally grips and securely wedges the peripheral edge portion of the covering sheet into compressed, hugging conformity against the flat side and bottom faces of the groove, thus serving to permanently lock the peripheral edge portion of the covered sheet therein.

The plastic trimming spline is then pressure wedged into the groove to provide a closure therefor. As thus constructed, the trimming spline is relieved of the upward pressure which would otherwise be exerted against the bottom face of the spline by the groove depressed edge portion of the covering sheet, because the underlying rattan strip has the capacity to firmly resist the upward pressure exerted thereon by the groove depressed portion of the covering strip, and remains immovably locked therein.

Covered table tops may be constructed in accordance with this invention without appreciably addin to the cost thereof over the cost of covered table tops as heretofore constructed. These improved covered table tops maintain their finished appearance through a lifetime of use, with the covering sheet remaining stretched. and taut at all times irrespective of changes in temperature or humidity conditions.

Other objects and advantages of this invention will become apparent as the disclosure proceeds.

Similar reference characters refer to similar parts throughout the several views of the drawing and the specification.

There is shown in Fig. 1 for purposes illustration, a perspective view of a typical table top to which the covering sheet has been applied. with its peripheral edge portion secured the: to by the improved locking means of this invention. While this improved locking means may be used to secure a covering sheet to table tops which are generally rectangular or any other desired shape, a table top is shown in Figs. 1 and 2 for purposes of illustration having a generally round or elliptical contour presenting an arcuate shaped apron frame I which may be built up from plywood presenting a finished veneer sheet 5 on the exterior thereof. The table top edging frame 2 may be formed from either straight or arcuate shaped sections whose abutting ends are glued together to present substantially invisible joints 3. The table top edging frame 2 is usually made from selected hardwood and is finished to present. a finished outer edge 6 and a flat top surface 5 which can be stained and lacquered or otherwise coated to present a finished table top surfacel A table top panel 6 has the peripheral edge thereof seated within a groove 1 formed in the inner edge of the table top edging frame 2 so as to be supported by an underslung shelf portion 8 forming a part of the edging frame 2. The table top panel 6 may be formed from laminated. plywood of sufficient thickness to provide ade quate strength, and its peripheral edge may be supported by and glued to the shelf portion 8 of the edging frame 2 to provide a rigid table top structure. The upper face 9 of the table top panel 5 should be smooth and flat so as to extend in the same flat plane as the top surface 5 of the edging frame 2, but need be given no special 5 finish since it is to be covered by the table top covering sheet 20.

A generally rectangular shaped groove H) of generally rectangular cross-section is cut into the upper surface 5 of the edging frame to receive the peripheral edge portion of the .covering sheet 28. The groove 10 is usually made approximately /l; of an inch in width and approximately 4 to of an inch in depth, and may .be selectively located in the upper surface 5 of the table edging frame 2 to leave uncovered the desired area '5 of the edging frame 2., leaving a selected marginal surface area 5 to be covered. The groove It may present straight runs which meet in relatively square corners as would :be the case when covering a rectangular shaped table top, or the groove '10 may present .-a continuous circular or elliptical run as would be the .case in covering a round or generally elliptical shaped table top as indicated in Figs. 1 and 2..

The groove It may be cut .by a circular saw blade suitably guided to properly locate the groove and to form a groove of the proper depth. As thus formed, the groove l presents a somewhat roughened inner side face I l and a roughened outer side face l2 which are substantially parallel, and a roughened bottom face [3 which is substantially parallel with the finished face of the edging frame. As indicated in Figs. 3, 4 and 5, the sawed groove H3 presents a relatively sharply defined upper inner corner I4, .a sharply defined upper outer corner l5, and sharply defined bottom corners IS. The roughened side faces I! i and i2 and the roughened bottom face is of the sawed groove H] present frictional surfaces which assist in retaining the peripheral edge portion of the covering sheet .20 securely locked in its final inserted position within the groove Ill.

The table covering sheet 2!) may be formed from natural or artificially simulated leathers, suitably coated textile fabrics, or selected plastic sheeting of various types, as commonly used for table covering purposes. The materials from which such covering sheets 2-0 are made have substantial strength and. wearability, and the better grades thereof are substantially resistant to heat, and will not easily burn or deteriorate under normal usage. Table covering sheets commonly employed also have a stretch characteristic when subjected to a tensile pull, but will tend to contract to its original form and size to the extent that the tensile pull is released. Such table covering sheets are usually made in various selected colors so that color harmony and color contrast effects may be achieved between the covering sheet 20, the trimming spline 35, and the finished surface 5 of the edging frame 2.

In accordance with this invention, the peripheral edge portion of the covering sheet is firmly and immovably secured in the receiving groove of the table edging frame in a manner to resist slippage or creepage of the edge portion for whatever cause, by the use of a rattan strip ill, which initially is substantially circular in section and whose diameter is approximately equal to the width of the groove ill into which it is to be inserted as indicated in Fig. 3. In applying the covering sheet 20 to the table top, the covering sheet is cut to the approximate shape of, but to a size somewhat in excess of, that required for covering purposes. The covering sheet 2b is spread over the table top with the center section 2i covering the table top panel '6, and with the peripheral edge portion thereof ex tending over the frame groove 10. The rattan strip .30 is then placed over that portion of the covering sheet 20 which spans the groove H) as shown in Fig. 3, and substantial downward pres sure a. as indicated at the right hand side of Fig. 2, is then applied to the rattan strip.

A pressure roller of narrow width so that it will snugly Sink into the groove may be rolled over the rattan strip 39 to thereby drive it into the groove. The rattan strip 30 is originally of such diameter that when it is forced into the groove iii by the pressure roller, it assumes a generally elliptical shape as indicated in Fig. 4, with the side faces 35 thereof substantially flattened. When the r ttan strip St has thus been driven to the bottom of the groove H), the peripheral edge portion of the covering sheet is drawn into the groove it without substantial distortion of the covering sheet, and so that the center section 2| of the covering sheet 2i! Will be drawn to lie flat and smooth against the top face 9 of the table top panel ii and the adjacent top face 5" of the edging frame which it is to cover, as indicated in Fig. 4. The peripheral edge portion of the covering sheet 2i! as thus initially inserted into the groove H] presents an inner side section 22 in hugging contact with the inner side face H of the groove, a bottom section 23 overlying the fiat bottom face :3 of the groove, and an outer side section 2 41 in hugging contact with the outer side face E2 of the groove. The fiattened side faces iii of the rattan strip as thus pressure forced into the groove have sufiicient roughness to firmly grip the smooth inside faces of the inner and outer side sections 22 and 24 of the covering sheet 29 which then line the side faces I i and iii of the groove.

When the rattan strip 333 has been pressure forced into the groove W as indicated in Fig. 4, the trimming spline 35 may be driven into the roove as indicated in 5. This may be accomplished by the use of a pressure roller which is rolled over the spline and exerts sufiicient downward pressure to wedge the splin 35 into the groove with the side face 33 of the spline in pressure contact with inner faces of the inner and outer side sections 22 and 2d of the covering sheet which line the side faces ll and I? of the groove. A rubber hammer may be used to finish driving the trimming spline into the groove, the flat bottom face 3? of the spline 35 being pressed against the rattan strip 30 to flatten the top face 33 thereof, and also flatten the bottom face 32 thereof, so that the rattan strip 33 becomes reshaped from its original round cross section as Shown in Fig. 3 into its final rectangula-r cross section as indicated in Fig. 6.

As thus finally flattened and reshaped, the rattan strip til presents fiat side faces 3! which grip the inner and outer side sections 22 and 24 of the covering sheet, a flat bottom. face 32 which seats flatly against and frictionally engages the flattened bottom section 23 of the covering sheet, and a fiat top face 33 against which the bottom face ill of the trimming spline 3'5 is pressed. The rattan strip 38 as finally forced into the groove it also presents substantially square bottom corners (i l which flatten the bottom section 23 of the covering sheet and prov-ides the bottol. section 23 with substantially square bottom folds 2"! which are wedged into the bottom corners 16 of the groove iii and in shaped conformity therewith.

While the trimming spline 35 may be employed to effect final flattening of the bottom face 32 and the top face 53 of the rattan strip 33 as indicated in Figs. and 6, it is preferable to effect final rectangular shaping of the rattan strip 3% b fore the trimming spline is inserted, as indii. Final rectangular shaping and the bottom face 32 and top face 33 of the rattan strip 39 may be effected by usin a flat rimmed roller loaded with ample pressure to flatten the bottom section 23 of the coverin sheet firmly against the bottom face i3 of the groove, and to wedge the corner folds 2'| thereof into the bottom corners it of the groove in tight shape conformity therewith. As thus pressure flattened, the rattan strip will permanently retain its rectangular shape with the bottom section the side sections 22 and B l of the ccv .g sheet tcnaciously gripped between the rou icned bottom face it and side faces El and if of the groove 59 and the rough and flattened bottom face and the rough and Fiat tened 5i "i the rattan strip .Zhe trimmin e may then be pressure wedged in supe d relation over the roller flattened rattan s with the side faces of the spline firmly pressed against the side sections 22 and of the covering sheet, following which the terminus end portion 25 may be cut off at 28 as shown in Fig. 6.

As an alternative procedure, the outer side section of the covering sheet 28 may be cut off at 28' as shown in 8 and the end section M thereof folded to overlie the flattened top face 33 of the rattan strip before the trimming spline is inserted. A trimmin spline is then selected which is slightly thicker than the trimmin spline 35 shown in Figs. 5 and 6, so that one face thereof will press against the inner side section of cov "lilg sheet 2% and the other face thereof will be wedged directly against the roughened outer face i2 of the groove it as shown in. 9. The trimming spline 35 may be wedged into the groove by a suitable pressure roller, and as finally driven in the groove the bottom face of the spline 35 will snugly seat against the underlying end section 2 3- of the covering sheet as shown in Fig. 10. Since the outer side face of the spline is in tight frictional engagement with the ro ghened outer side E2 of the groove, the -1ne 35 is securely locked in the groove, with the end section of the covering sheet wedged between the bottom face of the spline and the roughened upper of the rattan strip 1 the present practice to select a e LcLseS It has L trimming spline Cite as shown in Fig. 11 of the -num thickness permissible, and when the trimming spline fit-a is driven into the groove, it is intended that the peripheral edge portion of the covering sheet be thereby also driven into the groove. However, since the trimming spline is hard and unyielding the inner and outer corner folds 26a and 29a of the covering sheet have a tendency to bind against the relatively sharp inner and outer corners M and I5 of the groove. This undesired corner binding action prevents the center section 2! of the covering sheet from being drawn taut and smooth as the trimming spline 35a is driven into the groove, leaving the center section 2| loose and wrinkled. Further, when the bottom section 23a of the covering sheet is driven into the groove by the driving pressure exerted on the spline 35a, the side sections 22a and 26a and the bottom section 23a of the covering sheet will be substan- 8 tially stretched and. deformed as indicated in Fig. 12.

Thus as exemplified in Figs. 11 and 12, the previous practice of attempting to secure the peripheral edge portion of the covering sheet in the frame groove by means of the trimming spline has serious deficiencies since the unyielding spline causes the inner and outer folds 26a and 29a of the covering sheet to bind against the inner and outer corners M and I5 of the groove, thereby preventing the center section 2| of the covering sheet from being drawn taut and smooth over the table top, and additionally places the side sections 22a and 24a and the bottom sections 23a of the covering sheet under substantial stretch. As thus stretched, the side sections 22a and 24a and the bottom sections 23a of the covering sheet exert upward pushing pressure on the trimming spline 35a driven into the groove, and since the faces of the covering sheet in contact with the spline are relatively smooth and glossy, there is a constant tendency for the spline to creep out of the groove under the varying temperature and humidity conditions to which the table top is subjected during storage, shipment and use.

By driving the peripheral edge portion of the covering sheet into the groove by the use of an initially substantially round rattan strip 30 as shown in Fig. 4, the peripheral edge portion of the covering sheet is free to ride over the inner and outer corners M and iii in the groove in a manner so that the center section 2| of the covering sheet is drawn taut over the table top without imposing a deforming stretch on either the center section 2|, the side sections 22 and 2 1, or the bottom section 23 of the covering sheet. When the rattan strip 38 is then reshaped into rectangular form by roller pressure applied thereto, the squared side faces 3! and the squared botom face 32 of the rattan strip will frictionally grip the glossy surface of the side sections 22 and 24 and the bottom section 23 0f the covering sheet without substantial stretch deformation thereof, and in a manner to immovably retain the peripheral edge portion thereof permanently locked in fixed position within the groove :8, so that neither temperature nor humidity changes, nor normal use over long periods of time, will loosen the covering sheet as thus applied to the table top.

As thus constructed, the center section 2| of the covering sheet remains permanently taut and smoothly hugs the top face 9 of the table top panel 6 with the inner corner fold 26 of the covering sheet snugly folded over the upper inner corner M of the groove. When the trimming spline is driven into final position within the groove, its slightly arcuate outer face 38 is at an elevation between the top face 5 of the edging frame 2 and the smooth outer face of the center section 2! of the covering sheet.

In the embodiment shown in Figs. '7 to 10 inclusive, the end section 24' of the covering sheet 28 is wedged between the lower face 37 of the spline 35' and the rough and flat top face 33 of the rattan strip 343, so that the peripheral edge portion of the covering sheet cannot creep or slip, and since one face 35 of the spline 2: 5 is frictionally gripped by the roughened side face If of the groove It, immovability to the trimming spline as finally wedged into the groove is further assured. Further, since the peripheral edge portion of the covering sheet as pressed into the groove by the rattan strip 3 is under no appreciable tensile stretch, the groove inserted aeeonea 30 or the trimming spline inserted into the groove.

The employment of rattan strips 30 over which the trimming splines 35 are superimposed have been found to solve the serious p oblem of 1008- ening and creeping of the covering sheets as previously secured to table tops. The use of this improved. securin means for permanently and immovably locking the peripheral edge portion of the covering sheet to the table top does not add appreciably to the manufacturing cost of sheet covered table tops as heretofore manufactured, and yet insures substantial permanence to the construction under varying temperature and humidity conditions.
