NOSING FOR STAIR TREADS Application filed February 12, 1929.
This invention is an improvement in nosings for stair treads, and more particularly in a construction of nosing wherein the usual securing flange is eliminated.
The usual construction of nosing is composed of a covering flange, which fits the edge of the tread, and a securing flange, which rests upon the upper face of the tread, and has openings for screws, or the like, to connect the nosing to the tread.
The nosing is usually formed by extruding metal, such as brass or aluminum, through a suitable die, and the construction is relatively expensive, because of the weight of metal used, and because of the difficulty of extruding, due to the lateral drag of the securing flange.
In practice, the securing flange extends laterally from the inner or concave face of the nosing at a distance from one edge thereof. corresponding to the thickness of the floor covering, and the said flange is hidden beneath the covering. Thus in the usual construction, there is a large amount of relatively expensive metal concealed when the nosing is in place.
One of the primary objects of the present invention is the provision of a construction of nosing, wherein the securing flange as a continuous structure of the same length as the nosing is eliminated, and wherein means independent of the nosing strip is provided for connecting the nosing to the tread.
Another object is the provision of a construction which may be extruded without difliculty, and wherein the means for securing the nosing to the tread may be of relatively cheap material.
In the drawings forming a part hereof Fig. 1 is a perspective view of the improved nosing in place, with the parts in section.
Fig. 2 is a perspective view of the nosing looking from the inner side.
Fig. 3 is a similar view of an alternate construction.
Fig. 4 is a transverse vertical section of another embodiment of the invention.
In Fig. 1, the improved nosing is shown in connection with a stair tread 1, the nosing comprising a strip 2 of suitable material, such Serial No. 339,422.
as brass or aluminum, concave-convex trans versely, and relatively thick as shown. The nosing strip is of a width to cover the front edge of the tread l, and to extend above the tread as shown, a distance corresponding to the thickness of the floor covering 3, such as linoleum or the like, which is laid upon the tread, and when in place, the upper edge of the nosing is substantially flush with the surface of the floor covering.
The improved nosing is formed by eX- truding metal through a suitable die, and the means for securing the nosing to the tread is constituted by a plurality of plates 4, each of which has an opening 5 for the passage of a screw 5 or the like, to connect the plate to the tread. In the Fig. 1 construction, the plates 4 are separable from the nosing. Each plate has at one end a head 6, which is roughly dove-tail in shape, and the nosing strip has provided on the concave face thereof a longitudinally extending groove 7 which is shaped to fit the heads 6 of the plate.
That is, the side walls of the groove are I undercut, and the plates 4 are engaged with T5 the groove by slipping the heads 6 thereof into the groove from one end of the nosing. The fit between the heads and the groove is such as to enable movement of the plates longitudinally of the nosing, so that they may be suitably spaced on the tread, and it will be apparent that as many may be'used for each tread as may be necessary to hold the nosing in place.
The groove 7 is near one edge of the nosing as shown, the arrangement being such that when the plates are in place, and the nosing is connected with the tread, the upper edge of the nosing will be spaced above the upper face of the tread, a distance corresponding to the depth of the floor covering 3. In placing the improved nosing, as many plates 4 as may be necessary, are engaged with the groove. The nosing is now fitted against the tread, and the plates are connected, they being spaced from each other at the proper distance.
If desired, the plates may be permanently attached to the nosing as shown in Fig. 3, wherein the nosing is indicated at 8, and the attaching plates at 9. In this construction the plates 9 have one end bent angularly as shown at 10, to lit the concave face of the nosing, and these angular portions 10 are secured to the nosing at suitable intervals in any suitable manner, as for instance, by spot welding.
The plates 9 are so connected with the nosing that when it is secured to a tread, the upper edge thereof will extend above the up- 10 per face of the tread, a distance corresponding to the depth of the floor covering, and preferably the angular portion is of a width such that the free edge thereof will be substantially flush with the upper edge of the nosing.
In Fig. 4, the nosing indicated at 11 is similar to the nosing of Figs. 1 and 2, except that the groove 12 is rounded instead of dovetail. The securing plates 13, like the plates 4 of Figs. 1 and 2, have a head 14 at one end, similar to the head 6 of the plates 4-. The heads, however, are beads shaped to fitthe groove, and they may be inserted and placed in exactly the same manner as the plates 4 of Figs. 1 and 2.
It will be apparent from the drawing and description, that the improved nosing is easily extruded, and that it is relatively inexpensive in that the relatively expensive securing flange of the same material is dispensed with, being replaced by the s. a'ced plates, which may be of cheap materia and which are connected to the nosing after it has been extruded.
The construction shown in Fig. 4 has some particular advantage, in that the jointbetween the plates and the flange is a flexible joint, enabling a certain amount of adjustment between the flange and the securing plates.
What is claimed as new is 1. A nosing for stair treads including a strip to cover the edge of the tread, said strip being provided on one face with laterally extending longitudinally spaced and alined securing plates for connection with a stair tread, said plates being separable from the nosing.
2. A nosing for stair treads including a strip to cover the edge of the tread, said strip being provided on one face with laterally extending longitudinally spaced and alined se curing plates for connection with a stair tread, the nosing having a longitudinally extending groove in said face, and the plates having heads fitting the groove and slidable therein.
3. A nosing for stair treads, comprising a concavo-convex covering flange, and alined connecting plates connected to the concave face of the flange at spaced intervals.
4. A nosing for stair treads, comprising a concavo-colwex covering flange, and alined connecting plates connected to the concave face of the flange at spaced intervals, said plates being so connected to the flange that when they are secured to the tread the upper edge of the flange will extend above the tread.
5. A nosing for stair treads, comprising a concavo-convex covering flange, and alined connecting plates connected to the concave face of the flange at spaced intervals, said plates being so connected to the flange that when they are secured to the tread the upper edge of the flange will extend above the tread, said plates being separable from the flange.
6. A nosing or stair treads, comprising a concavo-convex covering flange, and alined connecting plates connected to the concave face of the flange at spaced intervals, said plates being separable from the flange.
7. A nosing for stair treads, COIl'lpllSlDg a concavo-convex covering flange, and alined connecting plates connected to the concave face of the flange at spaced intervals, the connection between the plates and the flange including a. longitudinally extending groove on the flange, and heads on the plates fitting the groove and slidable therein.
8. A nosing for stair treads provided on one face with laterally extending Iongitmlinally spaced and alined securing plates for connection with a stair tread, said plates be ing movable angularly with respect to the nosing.
9. A nosing for stair treads, comprising a concave-convex covering flange, and alined connecting plates connected to the concave face of the flange at spaced intervals, the connection between the plates and the flange ineluding a longitudinally extending dove-tail groove on the flange. and heads on the plates fitting the groove and slidable thereon.
10. A nosing for stair treads comprising a strip shaped and of a size to cover the edge of the tread, and means to connect the strip to the tread, including securing plates for connection to the tread, said plates and strip having interengaging means at the inner face of the strip to detachably connect the strip and the plates.
Signed at New York in the county of New York and State of New York this 7th day of February A. D. 1929.
