17 Claims. (Cl. -285) This invention relates to a bed frame and more particularly pertains to a bed frame of the knock-down or collapsible type comprising side rails and end rails formed of metal bars.

An object of the invention is to provide a bed frame of the above character which is adapted to be easily and quickly assembled and disassembled and when disassembled may be arranged into a compact package which will occupy but little space in storage or shipment and which may be readily handled and transported.

A particular object of the invention is to provide a construction in a bed frame whereby the ordinary bed-caster assembly may be utilized as a means for effecting an interlocking connection between the side rails and end rails of the bed frame to hold the frame in its assembled position and to equip the frame with caster supports and whereby on removing the casters the bed frame may be readily disassembled.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a perspective view of the bed frame in its assembled position.

Fig. 2 is a view in cross section and elevation as seen on the line 2-2 of Fig. 1. I

Fig. 3 is a detail in horizontal section taken on the line 33 of Fig. 2.

Fig. 4 is a detail in horizontal section taken on the line 4-4 of Fig. 2.

Fig. 5 is a view in elevation of a side rail of the bed frame as seen from the inner side thereof.

Fig. 16 is a plan view of one end portion of the bed frame shown in Fig. 15 in its extended position.

Fig. 17 is a view in section and elevation taken on the line of Fig. 16.

Fig. 18 is an enlarged section and elevation as seen on the line |8|8 of Fig. 16, and

Fig. 19 is a perspective view of an end portion of a side and end rail showing the parts inverted and in a folded or disassembled position.

Referring to the drawings more specifically, reference now being had to Figures 1 to 14 thereof, A-A indicate a pair of side rails and BB designate a pair of end rails of a bed frame, which rails are formed of metallic bars here shown as of L-cross section.

The side rails AA are each provided adjacent the ends thereof with metal brackets C-C which are securely fixed to the rails to depend therefrom. As here shown each of the brackets C embodies a fiat web 20 formed at opposed inner and outer ends thereof with inturned flanges 2| and 22. The inner flange 2| abuts the underside of the side rail A and is fastened thereto in conventional fashion with the Web 20 extending parallel with the side rail adjacent to the outer margin thereof. The outer flange 22 serves as a portion of a connection for an end of one of the end rails B, and is formed with an aperture 23 to receive the tubular socket member 24 of a conventional caster D which is Fig. 6 is an enlarged section taken on the line 26 beingspaced apart and aligned perpendicular 66 of Fig. 5.

Fig. 7 is a view in elevation of one of the end rails of the bed frame. I

Fig. 8 is an enlarged section and elevation as seen on the line 8-8 of Fig. 7.

Fig. 9 is an elevational view of a conventional caster wheel assembly employed as a connector between the side and end rails of the bed frame.

Figs. 10, 11, 12 and 13 are perspective views of inverted fragmentary portions of a side and end rail depicting the manner of effecting their assemblage.

Fig. 14 is a detail in section taken on the line ||4 of Fig. 2.

Fig. 15 is a plan view of a foldable bed frame to which a feature of the invention is applicable, showing the frame in a partly collapsed position.

' 26 spaced from the flange 22.

also engageable with the end portion of theend rail B supported above the flange 22 as will be later described.

The web 20 of each of the brackets C is fitted with a pair of

headed studs

25 and 26 which project from the inner face of the web medially of the side marginsthereof; the studs 25 and to the flanges 2| and 22 with the upper, stud 25 spaced from the flange 2| and the lower stud The

studs

25 and 26 serve as a means for detachable interlocking stud 26 affording a supporting connection between the bracket 0 and the rail end.

Each of the end rails B is formed with

upturned end portions

21 and 28 embodying a flange 29 formed at the upper end thereof with a notch 30 engageable with one of the studs 25 and formed on a margin thereof intermediate its ends with a notch 3| engageable with the companion stud 26. Each end portion of each end rail B is formed adjacent the base of the flange 29 with an aperture 32 arranged to register with the aperture 23 in the flange 22 when the end of the rail B is positioned above the latter; the aperture 32 being adapted to receive the socket member 24 of the caster D as particularly shown in Fig. 14.

In assembling the bed frame the side rails AA are arranged in suitable spaced parallel relation to each other in an inverted position,

whereupon the end rails are connected thereto in the manner illustrated in Figs. 10 to 13 inclusive;

the end rails B being initially positioned with; the end portions thereof laying sideways upon the then upwardly presented flange 2|, as

shown in Fig. 10, with the notch jp on-the end i of the flange 29 presented tothe stud 25 and with the notch 3| in the flange 29 extendedne upwardly. The end rail B is thenadvanced on.

the flange 2| in the direction indicated by the arrow a in Fig. 10, to bring the end notch -30-,

into engagement with the stud 25, whereupon, utilizinglthe stud 25 as a pivot the end rail is adapted to receive and snugly conform to the socket member 24 of a caster D.

Pivotally mounted on the outer end portions of the side rails E i-by pivot pins 42 are inclined brackets .G the outer-end portions of which are adapted to overlie the outer ends of the tube f ,40 when, the endrails F are disposed in their extendedposition as shown in Figs. 16 and 17.

ugThe brackets G will then extend inwardly and swung upwardly in the directionlindieated-by the 1 3 arrow 6 in Fig. 11 to advance the sideno'tchjl in the flange 29 into engagementwith the stud I 26 as shown in Fig. '12 The apertures\ 3 2 in the end portion of the end rails Bfwill thenbe disposed'inregi'sterwith the apertures 23 in .the flanges22 whereupon the socket members, of the casters'Dare inserted throughthe
