Abstract
Abstract A nonadjustable Hollywood bed frame in which the frame elements are formed from angle iron. The side rails and cross rails are so interconnected that the frame may be assembled and disassembled without the use of any screws, nuts, or bolts. To that end the cross rails are detachably connected to the side rails by either a bayonet and hook type connector or a lockable headed rivet and keyway type connector. A headboard may be connected to the end of the side rails in any of three different modes by a novel hinge connection arrangement between the headboard and the side rails.

Claim 1
Independent Claim
269 words
A bed frame comprising a pair of side rails, each of said side rails having a vertical leg and a horizontal flange, a pair of transverse cross rails detachably joining the side rails, each cross rail having a horizontal flange and a vertical leg, each rail having a pivoted end and a swinging end, a permanently attached pivotal connection between the horizontal flange at the pivoted end of each cross rail and the horizontal flange of one side rail, said pivotal connection permitting folding movement of said cross rails from a first folded position in which they are located parallel to the side rails with the horizontal flange of each cross rail contacting the horizontal flange of one side rail to a second position in which each cRoss rail is angulated at 90* to the side rail, the swinging end of both of said cross rails having a nonremovable projection extending upwardly from said horizontal flange of the cross rails, said projection having an integral enlarged head thereon spaced from said horizontal flange of the cross rail by approximately the thickness of the horizontal flange of said side rail, an angulated slot in the horizontal flange of each of said side rails adapted to detachably receive the projection of a cross rail, and a finger extending upwardly and outwardly from the swinging end of each of said cross rails, the outer end of said finger being adapted to be received over the top of the horizontal flange of said side rails when the projection on the same cross rail is located in an angulated slot of the side rail.
Claim 2
Dependent Claim
269 words
A bed frame comprising a pair of side rails, each of said side rails having a vertical leg and a horizontal flange, a pair of transverse cross rails detachably joining the side rails, each cross rail having a horizontal flange and a vertical leg, each rail having a pivoted end and a swinging end, a permanently attached pivotal connection between the horizontal flange at the pivoted end of each cross rail and the horizontal flange of one side rail, said pivotal connection permitting folding movement of said cross rails from a first folded position in which they are located parallel to the side rails with the horizontal flange of each cross rail contacting the horizontal flange of one side rail to a second position in which each cRoss rail is angulated at 90* to the side rail, the swinging end of both of said cross rails having a nonremovable projection extending upwardly from said horizontal flange of the cross rails, said projection having an integral enlarged head thereon spaced from said horizontal flange of the cross rail by approximately the thickness of the horizontal flange of said side rail, an angulated slot in the horizontal flange of each of said side rails adapted to detachably receive the projection of a cross rail, and a finger extending upwardly and outwardly from the swinging end of each of said cross rails, the outer end of said finger being adapted to be received over the top of the horizontal flange of said side rails when the projection on the same cross rail is located in an angulated slot of the side rail.
Claim 3
Dependent Claim
269 words
A bed frame comprising a pair of side rails, each of said side rails having a vertical leg and a horizontal flange, a pair of transverse cross rails detachably joining the side rails, each cross rail having a horizontal flange and a vertical leg, each rail having a pivoted end and a swinging end, a permanently attached pivotal connection between the horizontal flange at the pivoted end of each cross rail and the horizontal flange of one side rail, said pivotal connection permitting folding movement of said cross rails from a first folded position in which they are located parallel to the side rails with the horizontal flange of each cross rail contacting the horizontal flange of one side rail to a second position in which each cRoss rail is angulated at 90* to the side rail, the swinging end of both of said cross rails having a nonremovable projection extending upwardly from said horizontal flange of the cross rails, said projection having an integral enlarged head thereon spaced from said horizontal flange of the cross rail by approximately the thickness of the horizontal flange of said side rail, an angulated slot in the horizontal flange of each of said side rails adapted to detachably receive the projection of a cross rail, and a finger extending upwardly and outwardly from the swinging end of each of said cross rails, the outer end of said finger being adapted to be received over the top of the horizontal flange of said side rails when the projection on the same cross rail is located in an angulated slot of the side rail.
Claim 4

A bed frame comprising a pair of side rails, each of said side rails having a vertical leg and a horizontal flange, a pair of transverse cross rails detachably joining the side rails, each cross rail having a horizontal flange and a vertical leg, each rail having a pivoted end and a swinging end, a permanently attached pivotal connection between the horizontal flange at the pivoted end of each cross rail and the horizontal flange of one side rail, said pivotal connection permitting folding movement of said cross rails from a first folded position in which they are located parallel to the side rails with the horizontal flange of each cross rail contacting the horizontal flange of one side rail to a second position in which each cRoss rail is angulated at 90* to the side rail, the swinging end of both of said cross rails having a nonremovable projection extending upwardly from said horizontal flange of the cross rails, said projection having an integral enlarged head thereon spaced from said horizontal flange of the cross rail by approximately the thickness of the horizontal flange of said side rail, an angulated slot in the horizontal flange of each of said side rails adapted to detachably receive the projection of a cross rail, and a finger extending upwardly and outwardly from the swinging end of each of said cross rails, the outer end of said finger being adapted to be received over the top of the horizontal flange of said side rails when the projection on the same cross rail is located in an angulated slot of the side rail.
Claim 5
Dependent Claim
179 words
The bed frame of claim 1 which further includes a first hinge plate fixedly secured to the vertical leg of each of said side rails at one end of each of the side rails, a removable hinge pin, a second hinge plate pivotally connectable to the outer end of the first hinge plate by said removable pivot pin, said second hinge plate being attachable to a small headboard which extends between the two side rails in a first position in which a first vertical surface of said second hinge plate is located in a vertical plane spaced a first distance from and normal to the ends of the side rails, and said second hinge plate being connectable in a second position to a large headboard when inverted 180* relative to the first hinge plate and rotated 180* about the axis of the hinge pin, said second hinge plate when in said second position having a second vertical surface located in a vertical plane and spaced the same distance from the end of the side rails as said first distance.
