Abstract

The suspension of a door hinged within a frame for swinging movements in a horizontal plane includes an elongated metal cable with blocks secured upon its ends, with spaced apertures within the frame and door and with blocks projected into said apertures and supportably interlocked with the frame and door.

Claims

1. In combination, an apertured door frame;

a door nested within said frame;

an elongated hinge assembly interconnecting one upright door edge with a corresponding edge of said frame for swinging movements of said door in a horizontal plane; and

a flexible cable adjacent one end supportably anchored to and suspended from an upper portion of said frame, extending along said hinge and at its other end supportably connected to and suspending said door within said frame against downward movements relative to said frame.

2. In the combination defined in claim 1, further comprising spaced anchor means secured upon the ends of said cable, nested within and interlocked with said frame and door respectively.

3. In the combination of claim 2, further comprising said interlock including apertures within said frame and door with said anchor means nested within said apertures respectively.

4. In combination of claim 2, further comprising said flexible cable being adapted to be twisted before insertion of said anchor means providing for shortening the cable length for raising or lowering the door relative to said frame.

5. In the combination defined in claim 3, further comprising said apertures being of rectangular shape and said anchor means being metal blocks receiving and secured over end portions of said cable.

6. In combination an apertured door frame;

a door nested within said frame;

opposed upright continuous hinge housings of channel shape secured along their length to corresponding door and frame edges;

an elongated hinge assembly extending along the length of said hinge housings and flexibly interconnecting said hinge housings for swinging movements of said door in a horizontal plane;

an elongated flexible metallic cable adjacent one end supportably anchored and suspended from an upper portion of one hinge housing, extending along said housings and at its other end supportably connected to the other hinge housing to supportably connect and suspend said door within said frame against relative downward movements.

7. In the combination of claim 6, further comprising spaced anchor means secured upon the ends of said cable nested within and interlocked with said hinge housings respectively.

8. In the combination of claim 7, further comprising said interlock including apertures within said housings, with said anchor means nested within said apertures respectively.

9. In the combination defined in claim 8, further comprising said apertures being of rectangular shape and said anchor means being metal blocks of similar shape receiving and secured over end portions of said cable.

10. In the combination defined in claim 9, further comprising said blocks having a longitudinal bore, said end portions of said cable extending through said bores respectively;

said blocks being swaged over and compressively and retainingly engaging said cable ends and anchored thereon.

11. In the combination of claim 10, further comprising said bore being laterally offset.

12. In the combination defined in claim 9, further comprising said apertures being of limited oversize relative to said blocks, for cooperatively receiving said blocks and end portions of said cable respectively;

said blocks and cable being interlocked with portions of said housings against movements laterally and longitudinally when said cable is in tension supporting said door.

13. In the combination defined in claim 6, further comprising said cable suspension including opposed reversed turned hinge anchor flanges extending along said hinge housings;

there being a rectangular aperture within the anchor flange of one hinge housing adjacent its upper end;

and a corresponding rectangular aperture within the anchor flange of the other hinge housing intermediate its ends;

metal anchor blocks secured over end portions of said cable and projected into said apertures respectively;

and with said cable in tension said blocks being interlocked with said anchor flanges respectively against displacement up, down and laterally.

14. In combination, an apertured door frame;

a door nested within said frame;

an elongated hinge assembly interconnecting one upright door edge with a corresponding edge of said frame for swinging movements of said door in a horizontal plane; and

a rigid metallic rod adjacent one end supportably anchored to and suspended from an upper portion of said frame, extending along said hinge and at its other end supportably connected to and suspending said door within said frame against downward movements relative to said frame, the suspension of said rod and door including an aperture in said frame adjacent its top, and an aperture in said door intermediate its top and bottom, and metal anchor blocks secured over end portions of said rod, nested and retained within said apertures, respectively.

15. In the combination of claim 14, further comprising said rod being prestressed before mounting to allow the vertical rod suspension to act as a spring hinge.
