Wisconsin Application October 2, 1953, Serial No. 383,849 7 Claims. (01. 311M105) This invention relates to improvements in table 7 and more particularly to a protective corner plate for the juxtaposed ends of the reinforcing rails or channels underlying a tabletop.

The tops of certain types of tables are mounted on and reinforced by metallic rails or channels extending along the margins of the undersur- With the above in mind it is a primary object of the present invention to provide corner plates for the angular meeting end portions of table top reinforcing channels which provide a smooth and flush construction, covering and protecting all exposed edges of the corner portions of the reinforcing channels.

A further object of the invention is to provide table undersurface corner members which completely fill and protect the spaces between the ends of juxtaposed reinforcing channels and prevent the accumulation of dirt and foreign matter in such crevices.

Certain types of large folding tables which are used for banquets, groups and the like are normally stacked when not in use, and in stacked condition a surface portion of a superimposed table top may be stacked on the table-top channels of an underlying table. As these channels or rails, particularly at the corner portions, are normally rather narrow improper surface engagement and stacking may result.

With the foregoin in mind it is, therefore, another object of the present invention to provide table top corner members having enlarged horizontal surface portions which provide support and bearing surfaces for the corners of a superimposed tahle-top when a plurality of tables are stacked.

A further object of the invention is to provide a table corner construction which is relatively inexpensive and which can be applied to the underlying channels of the table top in a simple and expeditious manner, which is protective and neat and attractive in appearance, and which is well adapted for the purposes described.

j With the above and other objects in view the invention consists of the improvedtable corner construction and its parts and combinations as set forth in the claims, and all equivalent-s thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a fragmentary view of the exterior corner portion of a table top and the angularly related channels underlying the same with an improved corner member applied to and protectively connecting the juxtaposed ends of the angularly related channels;

Fig. 2 is a vertical sectional view through the corner portion of a table showing from the interior the improved corner plate and the manner in which it is applied to the juxtaposed ends of the reinforcing channels;

Fig. 3 is an inverted perspective view of a corner plate as applied to the juxtaposed ends of a pair of angularly related table top channels;

Fig. 4 is a vertical sectional view taken on line 4-4 of Fig. 2; and

Fig. 5 is a horizontal sectional view taken on line 5.-5 of Fig. 1.

In the drawing only a fragmentary corner por- Large tables of the type under consideration, when not in use, are customarily collapsed and a number of the same may be stacked for storage purposes with surface portions of their tops in engagement. As will hereinafter appear shelf portions of the improved corner plates l0 provide bearing surfaces for the engaging portions of stacked table tops.

and bottom right and 9" which are vertical wall portion and top angularly directed flanges 9' directed inwardly relative to the margins of the table top. For securing the channels 3 to the table top, screws H are passed through the upper flanges a into the plies of the table top 8.

The function of each corner plate It is, among other things, to bridge the space between the adjacent ends of a pair of angularly related channels 9 and to cover and protect the sharp metallic edges of the channels 8 which would otherwise be exposed. From the drawing it will be apparent that each corner plate Iii, prefer ably of metal, includes a vertical curved wall portion 12 co-extensive in height with the height of the vertical walls of the channels 9 and positioned to extend between the juxtaposed ends of the vertical walls of a pair of adjacent channels 9. However, the curved front wall l2 of a corner plate has its extremities inwardly offset and in underlapping relation to the forward end portions of the vertical walls of the adjacent channels 9, such inwardly offset underlapping portions of the corner plate wall It being designated by the numerals it, and from the drawing it will appear that the corner plate it is anchored in its interposed position by having said offset portions [3 spot welded or otherwise secured to the contacting portion of the vertical walls of the channels 9. Additionally the bottom margin of the exposed wall portion {2 of a corner plate ii! has formed integral therewith and at right angles thereto, a substantially fan shaped, inwardly directed horizontal plate or shelf at whose inner curved margin, between the bottom flanges E" of the adjacent channels, carries an upwardly directed collar if. said fan shaped plate portion Hi is sufficiently broad to overlap and cover the adjacent portions of the bottom flanges S3 of the channels and to guard the edges thereof.

It will thus be seen that the formation of a corner plate it is such that its curved vertical wall portion l2 forms a flush arcuate continuation of the vertical wall portions of the adjacent channels Si and the inwardly ofiset portions l3 thereof cover the vertical edges of the channels and permit the rigid securement of a corner plate to the adjacent channels bridged thereby. Moreover the fan shaped horizontal plate or shelf portion M of a member It covers and protects other edge portions of the adjacent channels and the edge protection is further enhanced by the collar i5. 7

When a table top ll is placed in the position shown in Fig. 3 and it is desired to superimpose another similar table top thereon for stacking and storage purposes either with its top in engagement or the channels in engagement, it will be evident that the horizontal plate or shelf portions Hi of the various corner plate members It provide substantial supporting or bearing surfaces for the corner portions of a superimposed table top or the channels thereof.

7 The improved table corner constructions substantially augment and finish the appearance of a table, cover and protect the sharp edges of the table top reinforcing channels at the corners, and are otherwise well adapted for the purposes set forth.
