Description

rete ted Mar. 12, 1940 UNITED STATES i PATENT OFFICE Thomas Witherbec Foote, Cleveland, Ohio Application January 1'7, 1939, Serial No. 251,287

1 Claim.

My invention relates to rubber wear strips or scuff plates used to protect the surfaces and corners of desks, chairs and other articles of furniture and has reference to the, particular construction of the wear strips and the means wherewhich. is concealed below the surface ofthe wear strip and whichholds the latter firmly in its ap plied position.

I accomplish the objects of the present invention by means of a combination of elements one embodiment of which is described in the follow- ,ing specification, set forth in the appended claim,

and illustratively exemplified in the accompanying drawing, in which:

Fig. 1 is a side view of a pedestal leg provided with a wear strip according to the present invention; v

Fig. 2 is a top plan View of the leg shown in Fig. l partly broken away on the horizontal section line 2-2 of Fig. 3; v

Fig. 3 is a transverse section on line 3'3 of Fig. 1; and

' Fig. 4 is a similar section showing the elements in a position before the striphas become finally attached to the leg.

Referring to the drawing, H denotes thepedestal leg of a chair having a narrow upper surface 62 to be protected by a wear strip. A series of nails I3 is driven into said surface along the 1ongitudinal center line thereof and at suitablyv spaced intervals. Each nail comprises va relatively large substantially circular head l4, dis- Fig. 2).

posed in spaced relationship to the surface l2,

and has its outermost lateral sections cut away on two chords parallel to the said center'line '(see The wear strip consists of an elongated strip l5 of elastic material having a Width substantially. equal to the width of the surface 12 to be protected, and provided with a convex upper surface l6, and a slightly concave lower surface IT. A longitudinal slot i8 is provided in the bottom side I! which slot widens inwardly into an undercut longitudinally extending passage IS, the greatest width of which corresponds substantially to the greatest transverse width of the rail heads I l. The passage 19 is thus defined by the solid downwardly projecting lateral flanges El separated by the slot I8. I i

In order to attach the wear strip if to the leg surface l2, thenails 53 are driven into the latter to about of an inch of their final position and the wear strip is then spread and passed over the heads M of the nails (see Fig. 4). Finally, the nails are driven into position by pressure or blows applied to the outer surface of the .wear strip. This flattens the convex under surface of the strip and holds it tightly against the surface of the leg.

I claim:

-A wear strip, comprising an elongated rubber strip provided with a longitudinal central slot in its under side, said slot widening inwardly into an undercut longitudinal passage, having the cross section of a trapezoid in which the two angles adjacent the side opposite the'slot are each less than forty-five degrees, the lower surface of the strip to the surface to be protected.
