This invention relates to a fol-dable bed frame which is constructed and arranged to take up a minimum amount of space when the same is collapsed for convenience in storage.

An object of the invention is to provide a foldable bed frame which is foldable from bed forming relation to collapsed lowered condition with oppositely disposed end sections of the frame arranged in upwardly projecting relation.

The invention comprehends a foldable bed frame of said character which includes similar end sections and a collapsible intermediate section hingedly connected with the end sections for movement from aligned bed forming relation to collapsed condition to dispose the end sections in upwardly projecting relation and the intermediate section in lowered relation to reduce the height of the collapsed bed frame for convenience in storage. Thus the height of the intermediate section when in lowered relation is independent of the height of the bed frame when in bed forming relation.

Still another object of the invention is to promediate section is supported on pivotally connected crossed legs which are linked to the end sections for effecting collapsing movement of the crossed legs and lowering of the intermediate section with the movement of the end sections to upwardly projecting relation.

Still another object of the invention is to provide a foldable bed frame having supporting members adapted to nati-y engage the supporting surface when in bed forming relation so as to prevent undue shifting thereof and which is also provided with rollable members adapted to engage the supporting surface when the bed frame is in collapsed relation to permit of convenient rolling movement of the bed frame.

Still another object of the invention is to provide means for supporting one of the end sections in inclined relation when the foldable bed frame is disposed in bed forming condition.

With the foregoing and other objects in View, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a side view of a foldable bed frame constructed in accordance with the invention and illustrating the same in bed forming relation.

Fig. 2 is a top plan View thereof.

Fig. 3 is a side' view thereof with the same shown in partially collapsed relation.

Fig. 4 is a similar view showing the bed frame in fully collapsed condition.

Fig. 5 is an enlarged transverse vertical sectional view taken approximately on line 5-5 of Fig. 1.

Fig. 6 is an enlarged vertical sectional view taken approximately on line 6-5 of Fig. 4.

Fig. 7 is an end view of the :bed frame.

Referring to the drawings by characters of reference, the ioldable bed frame consists of similar oppositely disposed end sections Ill and I I, an intermediate section I2 located between the end sections and a pair of pivotally connected crossed legs I3 and I4 arranged beneath the intermediate section at each side. The crossed legs I3 and Ul support the intermediate section in alignment with the end sections when the sections are disposed in bed forming relation and are linked with the end sections in such a manner as to collapse the crossed legs to substantially flattened condition with the movement of the end sections to upwardly projecting relation to thereby dispose the intermediate section in lowered position for reducing the over-all height of the bed frame when in collapsed condition. Thus the bed frame is reduced in height for convenience in storage and shipment when in collapsed condition without affecting the height of the frame when in bed forming relation.

The end sections [0 and I I each comprise oppositely disposed parallel side rails I 6 and I 'I andan end rail I8 which may be integrally connected with the side rails. The said rails are of angle iron construction and are arranged with the horizontal flanges I9 disposed uppermost and the vertical flanges 20 disposed outwardly. Each of the end sections is provided with a head 2l consisting of an inverted lJ-shaped member which is secured at its ends to the vertical iiange of the end rail I8 thereof to project thereabove. Each of the end sections is also provided with leg members 23 which are of angle iron construction and are pivotally connected on pivot pins 2t to the inner faces o-f the vertical flanges 2t of the side rails I6 and Il adjacent the outer ends thereof. The legs 23 are formed with inwardly bowed lower ends 25 which are join-ed by a cross member 26 to provide a firm support of U-shaped formation for each of the sections.

The intermediate section I2 includes oppositely disposed parallel side railsl 28 and 29 which are of angle iron construction and arranged with the horizontal flanges 30 thereof disposed uppermost and the Vertical flanges 3'I arranged' outwardly. The vertical flanges 3l of said side rails 28 and 29 project beyond the ends of the horizontal flanges 30 thereof into overlying relation with the inner ends of the vertical flanges 2li of the side rails of the end sections and are pivotally connected therewith on pivot pins 32 to permit of swinging movement of the end sections from horizontal alignment with the intermediate section to upwardly projecting relation therewith. The side rails of the intermediate section are formed with longitudinally extending slots 33 and 34 in the vertical flanges 3I thereof adjacent their opposite ends respectively through which extend pivot pins 35 and 36 which pivotally connect the upper ends of the crossed legs I3 and I4 with link members 31 and 38, the said link members being pivotally connected at their outer ends to the vertical flanges 2U of the side rails I6 and I1 of the end sections on pivot pins 39 and 40. Thus, one of the pairs of crossed legs I3 and I4 is arranged in supporting engagement with the side rail 28 of the intermediate section with the links 31 and 38 pivotally engaging the inner ends of the side rails I6 of the end sections and the other pair of crossed legs I3 and I4 is arranged in supporting engagement with the side rail 29 of said intermediate section with the link members 31 and 38 pivotally engaging the side rails I1 of the end sections.

The crossed legs I3 and I4 of each pair are pivotally connected together on a pivot pin 42 which extends through said legs substantially medially of the length thereof and through a bracket 43 riveted or otherwise aixed to the leg I4 thereof. A cross bar 44 is affixed at its opposite ends to the brackets 43 to dispose the same substantially in alignment with the pivot pins 42 to thereby rmly connect the pairs of crossed legs together for conjoint movement thereof from expanded to collapsed relation.

The side rails I6 and I1 of the end sections I and II are maintained in spaced apart relation at their inner ends by means of cross bars 46 and 41 which are affixed at their ends to the lower ends of short angle bars 48 pivotally connected at their upper ends to the side rails of the sections on the pivot pins 39 and 40 respectively.

In order to effect collapsing of the crossed legs from the set up position shown in Fig. 1 of the drawings to the collapsed position shown in Fig. 4 thereof with the intermediate section disposed in lowered relation, a link member 50 is pivotally connected at one end to each of the legs 23 of each of said end sections IIJ and II on a pivot pin I with the opposite end of each link member being pivotally connected to an angulated link member 52 by a pivot pin 53. The pivot pins 5I engage through the leg members adjacent their upper ends and the pivot pins 53 also extend through the projecting lower ends 54 of the short angle bars 48. The upper ends of the angulated link members 52 of the end section I0 are pivotally connected to the link members 31 on pivot pins 55 while the angulated link members 52 of the end section II are pivotally connected to the link members 33 on pivot pins 56. By this arrangement, the upper ends of the crossed legs I3 and I4 will be spread farther apart with the movement' of the end sections into upwardly projecting relation. This will dispose the pivot pins and 36 adjacent the outer ends of the slots 33 and 34 and the legs 23 will be moved to nested relation within the link members and in parallel relation with the side rails I5 and I1 as illustrated in Fig. 4 of the drawings. The cross bars 46 and 41 together with the short angle bars 48 will also be swung into close relation with the end sections. This nesting of the link members and the short angle bars into close relation with the end sections permits of the complete collapsing of the crossed legs I3 and I4 into close relation and the lowering of the intermediate section I2 into adjacent relation with the supporting surface to thereby reduce the over-all height of the collapsed bed frame for convenience in storage and shipment.

It is desirable to have the foldable bed frame rmly supported on a supporting suface at its ends and beneath the intermediate section when in bed forming relation. This is accomplished by means of the rounded lower ends 25 of the legs 23 of the end sections and in order to firmly support the intermediate section, a longitudinally extending angle bar 51 is provided for each pair of crossed legs. The said angle bars are slightly longer than the intermediate section and each includes a horizontal flange 58 adapted to flatly engage upon the supporting surface and a vertical flange 59 provided with longitudinally extending slots 63 and 6I located adjacent the opposite ends thereof through which slidably engage pins 62 and 63 having enlarged heads at their outer ends with the inner ends of the pins anchored in the lower ends of the crossed legs I3 and I4 respectively. Since the flanges 58 flatly engage upon the supporting surface, they provide a firm support for the crossed legs and the pins 62 and E3 being freely slidable in the slots therein facilitate the collapsing of the crossed legs with the movement of the sections from horizontal aligned relation to collapsed relation. The crossed legs are tensioned against collapsing thereof by coil springs 65 which are attached at their lower ends to the brackets 43 and at their upper ends to the legs I3 respectively.

Secured to the crossed legs I3 and I4 of each pair of crossed legs are angle brackets `IzI which are disposed with the flanges 61 thereof extending inwardly from the said legs and arranged in slight angular relation with the longitudinal side edges thereof. Mounted on the angle brackets 6G are caster rollers 69 which are disposed with the Shanks 10 thereof swivelly arranged in openings 1| in the flanges 61 to thereby swivelly mount the caster rollers on the crossed legs I3 and I4 with the axes of the Shanks 10 located substantially at right angles with reference to the length of the crossed legs. The rollable members 13 of the caster rollers 69 project inwardly of the crossed legs so that when the crossed legs are fully collapsed the rollable members 13 will project below the angle bars 51 into rolling engagement with the supporting surface whereby the foldable bed frame may be readily moved thereover when the same is in collapsed condition as illustrated in Fig. 4 of the drawings.

A wire mesh spring 15 is connected with and stretched between the side rails I6 and I1 of the end sections and the end rails I8 thereof and is connected with and stretched between the side rails 28 and 29 of the intermediate section for supporting a mattress thereon and which spring together with the mattress is adapted to be folded with the movement of the end sections to upwardly extending relation.

The cross bars 46 and 41 are disposed suffi,- ciently below the spring 15 to provide a clearance therebetween so that the spring does not contact with the said cross bars with the,Y weight of the mattress or person disposed thereon. One of the end sections, such as the section IU is provided with a Ll-shaped bail 'I1 which is pivoted to the vertical flanges 2li of the side rails l5 and l1 thereof on pivot pins 'I8 for swinging movement thereof to selectively engage, the outer ends of the pivots 5I in the notches 19 for supportingA the endv section I0 in inclined relation as shown in Fig. 3 of the drawings with the remaining sections of the foldable bed frame disposed in bed forming relation. This permits the use of the foldable frame for supporting a person in partially inclined relation thereon.
