Claim 3

A structure as defined in claim 1, wherein said first members are each partially formed as a longitudinally extending plate arranged transversely of an associated side rail, and co-directionally extending, channel forming flanges are planar and arranged on vertical longitudinal edges of the plate.

Claim 4

A structure as defined in claim 2, wherein said second transversely extending members are each formed as an L-shaped bracket formed by a pair of legs, with one leg arranged perpendicular to and provided with the connecting means and forming the portion dimensioned to mate with said channel for preventing a rocking movement between the two members, and the other leg arranged for supporting the bed frame.

Claim 5

A structure as defined in claim 1, wherein the members are arranged for normally lying in a vertical plane.

Claim 6

A structure as defined in claim 3, wherein the connecting means includes a pair of longitudinally spaced, keyhole shaped slots provided in one of the first and second members, and has a pair of pins provided in the other of the members and arranged for mating with the slots.

Claim 7

A structure as defined in claim 2, wherein the side rails are longitudinally extending, L-shaped angles, each having the first members connected to the inner surface of a leg thereof and arranged parallel to and spaced from the other leg, and said end rails are longitudinally extending T-shaped members provided with a stem, and the second members are L-shaped brackets having a leg connected to said stem and arranged perpendicularly with respect to the other leg which is provided with said at least one pin forming part of the connecting means.

Claim 8

In a bed frame defined by a pair of side rails and crossrails, a detachable and rigid connection between the side rails and crossrails, said connection comprising a vertically interlocked assembly including a pair of vertically disposed plates, means along vertically disposed side edges of one of said plates for forming a channel receiving the other plates and preventing the other plate from moving horizontally in the plane of the one plate, the plates abutting one another in parallel relationship, and keyhole slot and headed pin means on said plate means intermediate the side edges thereof for securing the plate means against each other when moved in one vertical relationship and enabling disconnection of the plate means when moved in the other vertical relationship.

Claim 9

In a bed frame defined by a pair of side rails and crossrails, a detachable and rigid connection between the side rails and crossrails, said connection comprising a vertically interlocked assembly including a pair of vertically disposed plates, means along vertically disposed side edges of one of said plates for forming a channel receiving the other plates and preventing the other plate from moving horizontally in the plane of the one plate, the plates abutting one another in parallel relationship, and keyhole slot and headed pin means on said plate means intermediate the side edges thereof for securing the plate means against each other when moved in one vertical relationship and enabling disconnection of the plate means when moved in the other vertical relationship.

Claim 10

The structure as defined in claim 7 wherein each of said plates is in the form of a vertical plate having substantially vertically disposed side edges, said means on the vertically disposed side edges including a pair of substantially parallel vertically disposed flanges projecting laterally to the same side of said plate with said flanges engaging the side edges of the other plate to prevent horizontal movement of the plates in the vertical plane of the plates.

Claim 11

The structure as defined in claim 8 wherein keyhole slot and headed pin means includes a pair of vertically spaced and aligned headed pins on one of said plates and a pair of vertically aligned and spaced keyhole slots in the other of said plates, each of said slots including a substantially circular opening at one end and a notch extending vertically from the opening with the side edges of the notch converging away from the circular opening for grippingly engaging opposed side surfaces of the headed pin between the head on the pin and the plate on which the pin is mounted.

Claim 12

The structure as defined in claim 9 wherein said headed pins are mounted on the plate having the flanges on the side edges thereof, said flaNged plate being mounted on the side rails and the slotted plate being mounted on the crossrails.

Claim 13

The structure as defined in claim 10 wherein said side rails and crossrails are of angular configuration including a horizontal upper flange and a depending vertical flange, said plate on the side rail being attached to the depending vertical flange adjacent the horizontal flange, said plate on the crossrail being of L-shaped configuration and including a vertical flange attached to the depending vertical flange on the crossrail, said plate on the crossrail including a depending tubular lower end portion for receiving a floor-engagement means.

Claim 14

The structure as defined in claim 11 wherein said plate having the headed pins thereon is provided with a pair of attaching lugs offset to the side of the plate opposite from the flanges for connection with the vertical flange of the side rail and rigidifying the vertical plate.

Claim 15

A detachable connection for connecting intersecting frame rails in a bed frame in which one of the frame rails is supported from a floor surface and the other of the frame rails is supported therefrom, said connection including a vertical plate depending from the supported frame rail and a vertical plate depending from the supporting frame rail, the plates abutting one another in parallel relationship, one of said plates having laterally extending substantially vertical and parallel flanges arranged forming a channel thereon for entirely receiving the other plate, said plates including means for interlockingly engaging one another that is engaged and disengaged in response to relative vertical movement between the frame rails with the interlocking engagement thereof being in the direction whereby downward forces exerted on the supported rail will retain the interlocking engagement.

Claim 16

A detachable connection for connecting intersecting frame rails in a bed frame in which one of the frame rails is supported from a floor surface and the other of the frame rails is supported therefrom, said connection including a vertical plate depending from the supported frame rail and a vertical plate depending from the supporting frame rail, the plates abutting one another in parallel relationship, one of said plates having laterally extending substantially vertical and parallel flanges arranged forming a channel thereon for entirely receiving the other plate, said plates including means for interlockingly engaging one another that is engaged and disengaged in response to relative vertical movement between the frame rails with the interlocking engagement thereof being in the direction whereby downward forces exerted on the supported rail will retain the interlocking engagement.

Claim 17

The structure as defined in claim 13 wherein said interlocking means includes a pair of vertically disposed headed pins on the plate on the supported rail and a pair of vertically disposed keyhole slots in the plate on the supporting rail, each of said keyhole slots having an upper circular portion and a depending notch portion defined by downwardly converging side edges for frictionally engaging the surfaces of the headed pin inwardly of the headed ends thereof whereby downward forces exerted on the supported rail will rigidly interlock the plates.
