Application filed February 3, 1928.- Serial No. 251,597.
This invention relates to vstair nosings i for stairs of various types, materials and forms embodying in the organization a re- 5 movable tread part, the entire organization being adapted to co-act with the resilient or cushioning stair treads ordinarily employed upon stairs.
A further object of the invention is to provide a stair nosing, preferably of metal, with improved means :for attaching the nos ing to the stair and `an improved type of tread part for non-slipping which said part is removably attached to the body of the l5 nosing. A
. lVith theseand other objects in view, the invent-ion comprises certain novel parts7 elements, units, combinations, constructions, interactions and functions as disclosed in the drawings together with mechanical and functional equivalent-s thereof, as will be hereinafter more fully described and claimed. i
Each of the 4figures of the drawings isl a transverse section taken on a perspective substantially at right angles to` the4 longin tude of the nosing and representing in each caseminor modifications involving the saine general principle throughout.V I l The stair nosing which forms the sublect matter of the present application comprises a. metallic or other approved type of strip properly contoured to fit over and upon the forward edge of a,` stair tread. This strip is formed in various shapes as indicated at 10, 11, 12. 13, 14, 15 and 16, to conformniore or less closelywith the shape of the edge of the stair tread,- or as shown at 17 in the form known as a bull nose extending beyond the edge of the tread.` In eac-h case the strip is provided with an undercut preferably of the type recognized as dove tailing and as shown respectively at 18, 19, 20, 21, 22, 23, 24 and 25. Opposite this undercut as disclosed at 18 to 25 inclusive, provision for'securing a nonslip tread in conjunction with the strip is provided. At 26,27, 28 and 29, this coniprises a shoulder integral with the undercut shoulders 18 to 25 inclusive for the receipt of tread strips.` To co-act with the specific type ot nosing strip havin(lr the second integral` shoulder a' tread strip is employed having a dove-tailed and has for an object to provide nosingsf or undercut furrow which is filled with any usual and ordinary compound or material preventing slipping as indicated at 30.
.Such strip for co-acting with the two undercut shoulders may in itself be formed as front flange 32 and a. rear flange 33, 'but instead of employing a double dove tail, the rearward shoulder is substantially right angle as indicated at 37. This permits the Vstrip to be snapped into place by introducing the forward edge under the undercut shouldery 22 or 23, and the rear edge forced downwardly to cover the screws 34.
This rear shoulder 38 may be formed upon a solid strip of material or may be formed hollow as indica-ted at 38 in Figure 5; It is tobe understood, of course, that the two types ot' tread strips shown at Figures 1 and' 5 are interchangeably usable with the two types of nosing strips as shown at said figures, and that the employment of either with the otheris only a matter of convenience or of choice. ,As shown at Figure 6, the arrangement of the undercut shoulders 23 and 29 are the saine as `shown at Figures 1 and', the diiference being in the formation of the front sideof the nosing as a bull nose. At this figure also it is indicated as being attached to a stone, cement or other hard substance as a stair tread and attached by meansA of the ordinary espansion bolt 39; y
In some locationsk and for some purposes, it is desirable to form the nosing strip with* out the rear undercut shoulder as indicated at Figure 2 in whichcase the flangeV 32 of the tread strip is as heretofore disclosed but the antislip material 30 is maintained in position by a strip 40, which is integral with't-he ange 32 but is secured upon the tread 11i not by engaging under or in relation to undercutI shoulders but by the screws 4l which pass through the strip 40 intov the nosing member ll which has before been secured to the stair tread by the screws 34.
As an enlargement upon the type shown at Figure 2, that shown at Figure 4 is substantially the equivalent but the strip 4Q corresponding to the strip 40 is here shown as provided with a groove which may and preferably will be V-shaped in cross section, although the invention is not limited to this particular shape ofi groove which is cmployed simply to add to the security of the tread.
In some locations and for some uses, one or hoth of the flanges 3Q and 33 may be pensed with. As shown at Figure 8, the
' flange 32 is still employed hut the flange 33 is omitted so that the dove-tailed member 44 at its rearward side is substantially flush with the strip 45 carrying the rear undercut shoulder. In this particular case, the strip 45 is independent of the nosing strip and is secured in position by the screws 34 which serve to holdthe nosing in position to hold the strip 45 in position upon the nosing and to retain the strip 44 intermediate such strip 45 and the undercut shoulder 25. As shown at Figure 3, both flanges have been eliminated and the strip 46 is provided merely with the two dove-tailed shoulders 4T and 48 which slide into contact with the shoulders 20 and 27.
As afsimplification, the type shown at Figure 7 employs a single strip which covers the upper edge of the stair tread and provides a dove-tailed furrow for receipt of the anti-slipping material 30 with an overhanging flange 49 for covering the front stepped edge ofthe stair tread cover 50. This is a type which is used upon stairs not subjected to heavy traffic and may be secured in position by screws as `indicated inthe other figures or by the nails 51 indicated at said Figure 7. i
In any ofthe modifications shown at the several figures, the one underlying principle has been adhered to of providing a stair tread with a strip of anti-slip material adjacent to the front edge of the stair tread so positioned as to be quickly and easily replaced when worn, making the maintenance of the stair in a relatively safe condition a comparatively cheapy and economical matter.
