2 Claims.

This invention relates to binding and dividing bars and particularly anchored bars used where an offset is provided for linoleum, or other applied flooring where it joins concrete, terrazzo, tile or other material.

When linoleum or composition flooring is used in rooms and corridors the most attractive, economical, sanitary, and practical installation is obtained by extending a cement or terrazzo border a few inches from the wall and use a binding .bar to form the offset for receiving the applied covering, and it is for this purpose that the present binding and dividing bar is intended.

The principal object of this invention is the provision of a binding bar having offset portions, and a base anchor of resilient material adapted to be snapped to position on said bar and then moved longitudinally therealong to permit proper leveling of the bar.

A further object of this invention is the provision of a binding and dividing bar having a base anchor provided with a horizontally disposed lip that serves as a depth gauge when setting the device in the plastic cement.

Other objects are economy of construction, ease of installation and adaptability to varying conditions due to irregular surfaces to which the device is to be fitted.

Minor objects will appear during the course of the detailed specification, referring to the accompanying drawings, wherein:

Like reference characters refer to similar parts in the several views and the numeral 18 designates a binding and dividing bar formed to provide grooves 20 and 22 on the reverse sides thereof, which are parallel and of different depths to accommodate floor coverings of difierer t thicknesses. The relative depths of these grooves may be varied or one of the grooves may be eliminated entirely as is shown in some of the modified forms. While the bar is shown in a straight form, yet it is apparent that it may be curved to any degree to conform to any desired design without altering the general structure of the device.

The bar I8 is also provided with ledges 24 and 25 which serve to support the edge of the fioor covering when its respective adjacent groove is positioned in the upper position, thus as shown in Figures 1 and 2, the ledge 24 is in planar relation to the concrete fill 28 and the floor covering 30 extends into the groove 26 and rests on ledge 24 thereby providing a smooth, level base for the floor covering that brings its top surface flush with the top of the bar and the outside border 32. The base anchor or plate 34 is preferably made of sheet metal of a desired degree of resiliency for purposes hereinafter set forth. The base anchor as shown in Figs. 1, 2 and 3, is stamped from sheet metal and consists of a body portion 36 having clamping tongues 38 stamped therefrom and bar supporting flanges 46 formed at right angles to said body member. Intermediate flanges G9 and the bottom portion of said base anchor is a horizontally disposed lip or step 42 which serves as a depth gauge to properly position the device in the plastic cement.

Referring to Figs. 1 and 2, it will be noted that the clamping tongues hook over one of the flanges M formed on the outer edges of the bar and cooperate with the body portion 36 and flanges 40 to maintain the parts in fixed vertical alinement while the base anchor is adapted to be moved lengthwise on the bar. Due to the resiliency of the material, the base anchor is snapped onto the bar at any point and will clampingly engage the same to prevent accidental longitudinal movement therealong. These base anchors are placed in spaced relation on said bar and in leveling the bar it may become necessary to move some of them to avoid unusually high surfaces or points in the floor slat 46.

When the bar as shown is placed in plastic cement, the cement will form and harden around the parts binding the bar securely in place with its upper edge exposed to present a dividing line Between the border 32 and floor covering 23. Furthermore, the top of the bar serves as a screed for furnishing border material to proper level while the ledge 26 also serves as a screed for striking off the inside fill 28.

The modified form as shown in Figs. 4, 5, 6, and '7 has a bar 50 having a head 52, a narrow body portion 54 and a downwardly extending V-shaped base 56 forming shoulders 58 on each side of body portion 54. Undercut shoulders 50 are formed at the juncture of head 52 and body 50. The illustrated embodiment of the specific type of shoulder 60 shown in Figs. 6 and '7, herein just referred to as undercut, may be each further described as having a downwardly and outwardly disposed face extending from a line on the shoulder close to and parallel with the proximal face of body portion 54 to the adjacent side of head 52 so that a longitudinal groove is formed which has its bottom closer to the top of head 52 than the remaining portion thereof. Such outward contouring prevents lateral movement of the ends of tongues 52 when the same are against the bottom of said groove, close to the body portion 54 and confined between the side of the binding bar and said face. The base anchor 65' has two sets of oppositely disposed clamping tongues 02 formed in spaced apart alinement to permit the positioning of the V-shaped base therebetween, so that they may be sprung apart and snapped to the position as shown in Figs. 4, 6 and T, with the tongues 62 engaging shoulders 50 and the detents 64 formed in tongues 62 engaging the shoulders 58, thus securing the parts together in such a manner as to permit longitudinal movement of the base anchor relative to the bar. The horizontally disposed step 65 serves as a depth gauge when setting the binding bar.

In Figs. 8, 9 and 10 a modified form is shown in which the bar 10 is of substantially angled form and has a vertical wall I2 and a horizontal base I4, thus forming a groove '55 for the reception of the edge of the fioor covering. The under side of the base is provided with an inverted T-shaped flange F8, thus forming grooves 85, into which ears 82 formed in end portions 84 of base anchor 85 are adapted to slidingly fit. Lips 88 struck from the body of the base anchor serve as depth gauges when placing the device in operative position. The inner face of wall 12 is grooved to present toothed ribs 90 which serve to engage the edge of the floor covering and secure it against upward movement.

The modified form shown in Figs. 11 and 12 discloses an angled bar I 00 having legs I02 on the outer surfaces of which are formed overhanging, oppositely disposed flanges I04 to form grooves I05, into which is fitted outwardly projecting ears I00 formed on the free edges of the resilient U-shaped base anchor MB. This base anchor is provided with a horizontally disposed gauge step H2 struck from the body of the base anchor. The base anchor is positioned by pressing the legs together and inserting the lips in the grooves I06.

The modified form shown in Figs. 13 and 14 provides for a bar I having oppositely disposed grooves I22 formed adjacent the base thereof in which the inturned flanges I24 of the U-shaped base anchor I25 are adapted to slidingly fit.

Depth gauge I26 is integral with the base anchor. Figure 15 shows a figure in which the base anchor is identical with that shown in Figs. 3, 4, 5 and 6, but with a bar I30 having a horizontally disposed ledge I32 and a downwardly disposed rib I3 l having an arrowhead edging I36.

The form shown in Fig. 16 discloses an angled bar I having grooves I42 formed in the outer surfaces of the legs respectively and a base anchor I4 1 having a body portion I46 provided with outturned step I08 adapted to fit in one of the grooves I42 and having securing tongues I50 with detents I52 which are adapted to be snapped into the other of said grooves. Depth gauge lip I55 is also provided for this form.

In view of the modification shown and described, it is apparent that many forms may be made without departing from the scope of the appended claims.

The modified form shown in Figs. 4, 5, 6 and '7 is especially adapted for use as dividing means to form an ornamental outline of panels of diiferent designs in floor construction of different materials, such as terrazzo, trap rock, cement and the like. This dividing bar eliminates the necessity of scoring and limits cracking of floors.

What I claim is:

l. A dividing strip assembly of the kind specified comprising a unitary binding bar having relatively thick portions formed along each longitudinal edge thereof to present laterally extending, opposed, spaced-apart shoulders on each side of the bar, parallel with the said longitudinal edges and spaced therefrom; and a relatively short anchor slidably mounted on the binding bar, having opposed staggered tongues thereon overlying the sides of said binding bar, the shoulders near one edge of the binding bar each having a downwardly and outwardly disposed face formed by the bar extending from the side thereof and combining with said side to form a groove, the ends of said tongues being seated in said grooves with the ends thereof between the side of the binding bar and said face to prevent lateral outward movement thereof.

2. A dividing strip assembly of the kind specified comprising a unitary binding bar having relatively thick portions formed along each longitudinal edge thereof to present laterally extending, opposed, spaced-apart shoulders on each side of the bar, parallel with the said longitudinal edges and spaced therefrom; and a relatively short anchor slidably mounted on the binding bar, having opposed staggered tongues thereon overlying the sides of said binding bar, the shoulders near one edge of the binding bar each having a downwardly and outwardly disposed face formed by the bar extending from the side thereof and combining with said side to form a groove, the ends of said tongues being seated in said grooves with the ends thereof between the side of the binding bar and said face to prevent lateral outward movement thereof, said tongues each having a detent struck therefrom in engagement with the opposed shoulders along the other edge of the binding bar to further prevent accidental withdrawal of the ends of the tongues from the said grooves formed in the first mentioned shoulders.
