' INVENTORY 4 YHARRYRAGINSKY ATTORNEYS BM M6 Patented Nov. 4, 1947 NETED STATES PATENT OFFICE Application May 25, 1944, Serial No. 537,298 In Canada May 9, 1944 6 Claims. (Cl. 205) This invention relates to improvements in the corner construction of bed-spring frames.

The corner members of bed-spring frames are usually heavy malleable iron castings provided with sockets in which the ends of the tubular side members of the frame are secured, the upper portions of the corner members being welded, riveted, or otherwise secured to the adjacent end frame members. In order to reduce the weight of the frame and for various other reasons it has been proposed to replace the cast iron corner members with lighter corner members made of fabricated sheet metal of relatively thin gauge. The fabrication of sheet metal corner members of sufficient strength and rigidity to withstand the service strains imposed thereon is far from a simple matter and requires the use of intricate stamping or bending dies which add greatly to the cost of production.

The object of the present invention is to provide a generally improved bed-spring frame ineluding angle iron corner members which are produced by a simple and inexpensive method of fabricating suitable lengths of rolled angle iron stock, the finished corner members being characterized by properties of strength and rigidity comparing favourably with those of cast iron corner members and being of simpler design as compared with both the cast corner members and the fabricated sheet metal corner members now available.

Several preferred embodiments of the invention are illustrated by the accompanying drawings, in which Figure 1 is a perspective view of a corner portion of my improved bed-spring frame and shows the manner in which my improved corner member is designed and connected to the adjacent side and end members of the frame. This view shows the corner member as it appears when looking toward the outer side thereof.

Figure 2 is an end elevation of the assembly shown in Fig. 1.

Figure 3 is a perspective View of a modified arrangement which may be used in place of "that shown in Figures 1 and 2; and

Figure 4 is a further perspective view of said modified arrangement as it appears when viewed from a different angle.

In the construction shown in Figs. 1 and 2, my improved corner member is generally indicated at 5 and is shown connected between the side and end members 6 and l of a bed-spring frame 8 which includes the conventional spring fabric 9.

The corner member 5 comprises a length of rolled angle iron presenting flanges Ill and II lying at right angles to each other. The side frame members 6 comprise a length of tubing which is flattened at each end to provide a vertically disposed flattened portion 6a. The end frame member 1 preferably comprises a length of rolled angle iron presenting a vertical flange la and a horizontal flange lb; the latter extending inwardly from the upper edge of flange la, toward the transverse centre of the bed frame.

The corner member 5 is arranged so that its flange l l forms the outer side of said member and lies parallel with the adjacent side rail l3 of the bed frame with which the bed-spring frame is associated. The lower end of flange II is bent outwardly to provide a laterally directed bedspring frame supporting member I la which rests on and is supported by the upper surface of the bed frame rail l3. The flattened portion 6a of the side member 6 of the bed-spring frame is fitted against the inner side surface of the corner member flange I l and is secured thereto by rivets I4 or by welding or other suitable fastening means. The flange ll! of the corner member 5 extends inwardly from the companion flange II in a direction substantially parallel with the vertical flange la of the end member I and the upper portion of the corner member flange I0 is welded, riveted or otherwise secured to the end member flange la in supporting engagement with the lower face of the end member flange lb, the said flange lb of end member I being also supported by the upper end edge of the corner member flange II.

The component flanges is and H of corner member 5 are bent as shown in the drawings so that the upper and lower portions thereof which are respectively secured to the bed-

spring frame members

7 and 6 are offset from each other to lie in parallel vertical planes and are connected together by intermediate inclined portions of said flanges. As shown in the drawings, the lower portions of the flanges It! and II of the corner member 5 are offset inwardly with respect to the upper portions of said flanges so as to effectively prevent the end frame members 1 of the bedspring frame being pulled toward each other by the tensioning of the bed-spring fabric 9 when the latter is under load.

The supporting extension I la formed by the outwardly directed lower end portion of the corner memberflange ll lies in an elevated plane with reference to the lower end edge of the corner member flange HI and the portion of the flange I3 which projects below said extension Ila serves as a stop which is engageable with the 3 inner side of the bed rail l3 to prevent lateral displacement of the bed -epring frame.

In the modified arrangement shown in Figs. 3 and 4 the corner member 5 is formed with flanges l5 and I6, the flange l5 lying parallel with the vertical flange la of the end frame member I and the flange l6 lying at right angles to said flange la. In this case the corner member flange l6 constitutes the outer side of the corner member and has its lower end bent outwardly to provide a laterally directed supporting extension 15a which rests on and is supported by the upper surface of the bed rail l3. The lower end of the flange I5 is also bent to provide a supporting extension l-5a which is directed inwardly toward the transverse centre of the bed-springframe and which serves as a support for the side frame member 6 which, in this particular case, is arranged so that its flattened portion 6a lies in a horizontal plane and is supported on and riveted or otherwise secured to the upper surface of said supporting extension Mia. The flattened portion 6a, of the side frame member 6 is shaped so that its end edge bears flatly against the portion of the corner member flange l5 lying immediately above the extension 15a. In all other respects the'corner member shown in Figures 3 and 4 is substantially the same as that shown in Figs. 1 and 2.

In connection with the arrangement shown in Figs. 3 and 4 it will be noted that the tubular portion of the side frame member 6 lies, in part, below the upper surface of the bed rail 53 and serves as a stop engageable with the inner side of the bed rail to prevent lateral displacement of the bed-spring frame.

Havin thus described what I conceive to be the essential features of my invention and several preferred embodiments thereof, it will be understood that various modifications may be resorted to within the scope and spirit of the invention as defined by the appended claims.

I claim:

1. A bed-spring frame comprising end members, angle iron corner members each having one flange thereof flatly secured to one of said end members and tubular side members extending between the corner members of each side of the bed-spring frame, said tubular side members being formed with flattened end portions flatly secured to flanges of the corner members between which it extends, one flange of eachcorner member having its lower end bent outwardly to provide a lateral extension adapted to rest on a side rail of a bed frame with which the bed-spring frame is associated.

2. A bed-spring frame comprising end members, angle iron corner members secured to and extending downwardly from said end members, one flange of each corner member having its lower end bent to lie in a horizontal plane and tubular side members connected between the cor ner members at each side of the bed-spring frame, each of said tubular side members being formed with flattened end portions disposed to lie in a horizontal plane and flatly secured to the said horizontally bent flange portions of the corner members between which. said side members extend.
