ADJUSTABLE BED FRAME Filed May 13, 1959 United States Patent O 3,003,158 -Y ADJUSTABLE BED FRAME John G. Sevcik, Berwyn, Ill., assignor. to Burton-Dixie Corporation, Chicago, Ill., a corporation of Delaware Filed May 13, 1959, Ser. No. 812,914

j 2 Claims. (Cl. 5-181) The present invention relates to bed frames and especially Ito a novel bed frame-capable of ready adjustment to different widths, such as to form a single, double or intermediate bed.

While bed frames have been designed that are capable of adjustment, they `downot provide for the ease and positive retention of the adjusted components as does the present invention, nor do they provide for the ultimate strength, rigidity and stability'requiredtin a bed frame capable of being adjusted to plural positions of'adjustment.' In the 4presentwassembly, the Icomponent parts when anchored in adjusted position provide a novel threepoint suspension assuring maximum rigidity and stability in the adjusted frame assembly.

Another important object of the present invention is to provide an adjustable bed assembly which permits a dealer to supply the bed frame wants of his customers without requiring such dealer to carry in stock bed frames of the various sizes now required to be carried. According to present practice, the dealer must stock two and genera-ily three sizes of bed frames of the so-called Hollywood type of bed which has no footboard, one being the single or twin size bed, another the double bed size and a third having a width between the other two and frequently referred to as a three-quarter size bed.

Thus the present novel adjustable bed frame relieves the dealer from the necessity of carrying in stock multiple sizes of the present type of bed frame to satisfy his customers wants. Not only does he appreciably reduce his inventory, but the customer is assured that he can use the same frame should he later decided to convert the frame to a larger or smaller size bed.

Another important advantage of the present invention is that it enables the frame to be shipped and stored in assembled relation, instead of in separate pieces. Furthermore, the complete assembly may be readily collapsed into a minimum of space in which the parallel side rails are disposed in contiguous relation, and merely requires the customer, when the assembly is delivered, to extend the frame by pulling apart the side rails to approximately the size of bed frame desired; i.e. whether a single, threequarter or double bed size, and then to insert a locking pin on one end of each of two connecting cross rails into one of three openings provided in the adjoining side rail. This is all that is required to lock the side rails in their adjusted position in which the frame assembly is ready to receive the usual bed or box spring and mattress.

Further objects are to provide a construction of maximum simplicity, efiiciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

In the drawing:

FIGURE 1 is a plan view of an adjustable bed frame embodying the present invention, the parts being shown in full lines in an adjusted position for an intermediate width of bed and in dotted lines in a fully expanded position to form the frame of a double bed and also in fully retracted position for a single bed.

FIG. 2 is a view in side elevation of the adjustable bed frame of FIG. 1.

FIG. 3 is a fragmentary enlarged view in perspective of the upper or outer side rail of FIG. 1 and showing an end of a connecting cross rail and an adjoining adjusting bar connected thereto.

3,003,158 Patented Oct. 10, 1961 ICC ' necting cross rails or brace members 12 and 13 and connecting adjusting arms 14 and 15, the cross railsv each having its upper ange 16 pivotally connected at one end at 17 to the lower horizontal flange 18 of a side rail, and its otherend provided with a depending pin or stud 19 adapted to be received in one of three spaced apertures or openings 21, 22 or 23 in the horizontal ange 18 of the other side-rail. i

In the full vline position of FIG. 1, the depending pin 19 'at an end of each cross rail is shown inserted in the intermediate opening 22'to provide a bed frame adapted to receive a bed or box spring of so-called three-quarter size or'width. 'In the dotted line positions of FIG. l, the pin-s 19 are shown received'in the openings 23'of therside rails when the frameis fully expanded 'to form a double bed and also in the openings 21 of the side rails to provide a single or twin size bed.

The side rails 10 and 11, connecting cross rails or brace members 12 and 13, and connecting adjusting bars 14 and 15, are each formed of an angle member for maximum rigidity, with the horizontal flange 18 of each side rail disposed at the bottom and directed inwardly from its vertical ange 24 defining the width of the adjusted frame to receive and accommodate a bed spring or box spring and mattress, not shown.

Each adjusting bar 14 and 15 is pivotally connected at one end at 25 to the upper or horizontal llange 16 of a cross brace member 12 or 13 intermediate its length, and the other end of each adjusting bar is pivotally connected at 26 to the lower or horizontal flange 18 of a side rail 10 or 11. As shown in FIG. 3, the end of each cross rail 12 and 13 and the end of each adjusting bar 14 and 15, has its depending or vertical flange 20 cut away at 27 to permit free pivotal movement of these members.

The apertures 21, 22 and 23 and depending pins or studs 19 locate the positions of adjustment of the present novel bed frame, the pins 19 in the apertures 21 locking the parts in position for a single or twin bed, the pins in the apertures 22 for a three-quarter size bed (shown in full lines in FIG. 1) and the pins in the aperture 23 for a double bed. In any of said positions there is provided a rigid three-point suspension; i.e. each end of a connecting cross rail or brace member 12 or 13 joined to the opposite rails 10 and 11 and the end of an adjusting bar 14 or 15 pivotally connected at 26 to a side rail. This provides an extremely rigid and adequate supporting base for the bed or box spring, mattress and occupants.

The side rails 10 and 11 are shown provided with a leg 28 and a caster 29 adjacent each end and at one end each side rail is provided with a depending bracket 30 for mounting and supporting a headboard (not shown), if desired.

The universal frame of the present invention due to its novel adjustable features and its compact construction when collapsed for shipping or storage has important advantages not only for the manufacturer, but also the shipper, the dealer and the user, and is both economical to produce and convenient for adjustment to the desired purpose.

Having thus disclosed the invention, I claim:

1. An adjustable bed frame, comprising a pair of angle members forming parallel side rails, each having a horizontal rail provided with spaced openings intermediate its length, a pair of angle members forming parallel cross rails extending obliquely across and joining said side rails in each position of adjustment, one end of one of said cross rails being aixed and pivotally connected to adjacent one end. of a side rail and one end of the other erossy railv being aixed,` and pvotally eerilleeterlA to, and

adjacent the opposite end of the other side rail, the other end of each cross rail having a depending Stud received in one 0f the Openings inthe opposite side: rail to provide a bed frame of; a desired width, and a ofparallel adjusting` arms pivotlally connected at onerendy to the end of each side rail opposite to the pivotal connection betweeny said-` side rail and cross rail, theI other end of each adjusting arm pivotally connected to an; intermediate portion of the adjacent crossv raill thus providing` a rigid three pointsuspension.

2-. An adjustable 'bed frame, consisting of; a pair of parallel; side rails, each side rail formed of an angle member having an outer upwardly extending vertical flange andM an: inwardly extending horizontal flange with the latter having spaced openings intermediate its ends and the ends of said side rails having depending supporting legs,l a pair of parallel crossv rails extending obliquely across and joining said` side rails to form a bed frame with oneend of a cross rail' pivotally connected to and adjacent one end off a side-rail and oneA end of the other cross rail pivotally connected to the opposite side rail adjacent the opposite end of the latter, the other end of .4 each cross rail having a depending stud received in one oithe. intennediate openings, in. the epnesite side rail to provide a `desired width of Asaid bed frame in each of which adjusted positions the cross rails extend oblique to the side rails, and a pair of adjusting bars each having one end aixed and pivotalljr connected to and adjacent the other end of aside rail opposite the pivotal connection of its cross rail, the other end of each adjusting bar being affixed'v and` pivotaliy connected to an intermedi-ate portion of the adjacent cross rail, each cross rail and adjusting bar formed of an angle member with a downwardly extending vertical ange cut away adjacent their pivotal connections for free pivotal movement in adjusting the size of the bed frame.
