I

As known, of late it has been customary for a bedstead manufacturer to ship his product in the form of a set of various components or subassemblies complete with a bag of additional parts and hardware plus printed assembly instructions, with the latter being usually so poorly written as to overwhelm the purchaser.

This invention derives from the acknowledged fact that a crib or like bedstead, upon arrival in disassembled form at the home of the ulimate purchaser, presents outlandish problems for the consumer who, by the law of averages, is totally inexperienced in and completely unqualified for the exasperating work represented in any assembly effort.

Herein I provide a method of rapidly assembling such a bedstead. In trial tests involving over 250 different people asked to assemble any of the bedsteads hereof, the average assembly time was 35 seconds.

Additional to a method of assembling a bedstead, I provide herein a structure with respect to the design and configuration of certain of its instrumentalities and their coaction whereby the ready assembly can be rapidly achieved by even the most technically unskilled person.

The basic concept envisions the provision by the manufacturer of an assemblage of such bedstead subassemblies complete with associated hardware strategi cally fitted thereto to the end that the subassemblies, upon receipt by the purchaser at ulitmate destination, can be readily assembled into a complete bedstead with a minimum of distress and aggravation and with the additional benefits of greater rigidity and improved appearance.

Of course, it follows that the reverse procedure permits ready disassembly by the owner in the event the crib is desirably moved from room to room or house to house.

One other significant purpose of the invention is to provide a crib or bed so structured that it may be taken apart and folded into a convenient compass, as for storage purposes, without the attendant frequent loss of small parts making reassembly difficult if not impossible. And this is not to slight the fact that the entirety of the problem arises ab initio because of the obvious economics of the shipping problem dictating that the product, in movements from manufacturer to wholesaler and/or retailer and thence to consumer, be packaged in disassembled form. In the drawings:

FIG. 1 is a view, in side elevation, of a crib embodying some of the features of the invention;

FIG. 2 is an enlarged fragmentary view, in side elevation, of one of the connectors of the invention;

FIG. 3 is an enlarged fragmentary view, in top plan, of the FIG. 2 components;

FIG. 4 is an enlarged fragmentary view, in front elevation, of a female half part of a connector secured to an end rail of the back or front of a crib;

FIG. 5 is an enlarged fragmentary view, in front elevation, of a male half part of a connector secured to an end rail of a side of a crib;

FIG. 6 is a fragmentary view, in side elevation, showing one end of a side and back or front .ofacrib of the prior art;

FIG. 7 is a view, in side elevation, showing the FIG. 1 crib converted to a youth bed; and

FIG. 8 is a view, in front elevation, showing the back or operating side of the foot member of the FIG. 7 youth bed.

The invention is based upon two primary desiderata: (1) to enable any ulimate purchaser to fully assemble a bedstead within a matter of seconds and without a multitude of small parts, and (2) to satisfy the esthetic sense by the provision of a crib or'youth bed or combination crib-convertible-to-youth-bed which, when assembled, will have a desired appearance, that is with the avoidance of any freakish look due to the presence of additional components.

With reference first to the prior art, the usual crib is comprised of a headboard subassembly, generally indicated by 10, and made up, as known, of either a solid end panel or a plurality of vertically-disposed rails framed as by suitably spaced horizontally-extended top and bottom cross rails and also by suitably spaced opposite vertically-extended end rails (one of wiich is shown as 12 in FIG. 6) serving as corner posts and extending downwardly below the plane of the bottom cross rail to define legs 14 which may or may not be equipped with the usual casters 16.

Similarly, the footboard subassembly at the opposite end is comprised of an end panel or plurality of rails framed by spaced horizontally extended top and bottom cross rails and spaced opposite vertically extended end rails similarly serving as corner posts and extending downwardly below the plane of the bottom cross rail to define legs likewise caster-equipped, if desired.

Further in this prior art recital, we would call attention to the usual side subassemblies extended between the opposite head and footboard subassemblies, on opposite sides of the crib, and herein generally indicated by 30 in FIG. 6.

Each side subassembly comprises the usual spaced top and bottom horiziontally extending cross rails 32 and 34 respectively and spaced vertically extending slats 36 interconnecting therebetween.

One or both side subassembleis may be provided with conventional drop-facilitating means usually but not necessarily in the form' of such as a foot-operated gate shoe component with a spring-pressed pivoted latch, all whereby the respective s'ide subassembly may be held in an upper crib-enclosing position or dropped therefrom to a lower crib-non-enclosing position. Such a means is not exemplified in the fragmented prior art showing of FIG. 6, but is shown in the FIG. 1 representation of the invention where it is indicated by numeral 40.

With continued reference to FIG. 6, such dropping is facilitated by means of drip side slide rods 42 associated with each endof each headboard and footboard subassembly. Each such drop side slide rod is offset at its upper end at 44 for detachable securement thereat to the respective end rail as by a screw of bolt and is disposed in spaced parallelism with the respective end rail, there being an apertured lower bracket 46 strategically located relative to and mounted on the respective leg and adapted to receive through its opening the lower free extremity of the respective drop side slide rod. Additionally, the rod is extended through suitable aligned vertical openings in the upper and lower cross rails of the respective side subassembly.

Each end rail 12 is further provided with an upper bracket 48 through which the respective rod is passed and a bumper spring 50 seated on each lower bracket 46 and against which the respective bottom cross rail 34 of the side subassembly will rest when in side subassembly lowered position.

The headboard and footboard subassemblies are spaced as to each other by the usual mattresssupporting spring means 60, mounted'in any practical manner, as for example by an inter-engagement of lugs 62 usually unitary with and projecting outwardly from the spring at opposite ends thereof and verticallydisposed spring means suspension brackets 64 provided on each said end rail 12 and offering a plurality of vertically-spaced selective levels or planes along which the spring means may be disposed.

Spring means 60 upwardly supports the conventional mattress 66.

So much for the well known prior art construction.

Not so well known with respect to the prior art is that it is normal to package and sell such crib in unassembled form, with the headboard andfootboard and subassemblies being packaged each in assembled subassembly form, leaving to the consumer the unhappy task of adding the packaged hardware i.e., drop side slide rods 42, lower brackets 46, upper brackets 48, bumper springs 50 suspension brackets 64 and requisite screws or bolts in the right places'at the right sequence in time of assembly so as to achieve a fullyasser nbled crib.

In the case of the crib of the'inventiofi, the headboard, footboard and sides are factory-assembled as as by top and bottom cross rails and opposite end rails 122 serving ascorner posts and extending downwardly to define legs 124 which may be equipped with casters To the end of avoiding unnecessary duplication of figures inthe drawings, in FIG. 1, end rail 112 is shown as being separate from leg 113, all for a purpose subsequently to be referred to.

A side subassembly 130, made up of spaced top and bottom horizontally extending

cross rails

132 and 134 respectively and spaced vertically extending slats 136 interconnecting therebetween, is provided on each side of the crib.

The most significant and innovative feature of the invention is now to be described. At each opposite end of each side subassembly, an additional verticallydisposed supplemental end rail 138 is provided and to which a drop side slide rod 142 with an upper offset 144 is secured as by a screw or the like. The drop side slide rod is extendable through suitable aligned vertical openings in the upper and lower cross rails of the respective side subassembly and also through lower and

upper brackets

146 and 148 respectively mounted on the supplemental end rail.

A bumper spring 150, sleeved upon the drop side slide rod, seats on lower bracket 146, wherefore the side subassembly is cushioned when dropped into lowered position.

The supplemental end rails may mount suspension brackets 164 for receiving lugs 162 extending outwardly from a spring means 160 upon which a mattress 166 may be supported.

The salient point is that all of this so-far-described hardware is mounted on the supplemental end rails at the manufacturing site and incorporated into the side rails subassembly and made a part thereof so that said side rail subassembly is shipped in disassembled form with the other subassemblies to form a package representative of a complete crib ready for quick assembly at ultimate destination.

The quick assembly is further made possible for the provision at each end of each side subassembly of pairs of female (or male) half parts of connectors 170, the complemental pairs of male (and female) half parts being strategically mounted on the confronting faces of

end rails l

12 and 122 of headboard or footboard subassemblies 1 l0 and 120 respectively, and the supplemental end rails 138 of side subassemblies 130.

The male half part of connection 170 is best shown in FIG. 4 as comprising a plate 171 suitable for securement to an end rail or supplemental end rail as being same as 172, which plate is provided with a forwardly facing vertically extending slip joint 173, the inside side walls of which are tapered inwardly from top to bottom so as to becomplementally receivable in bayonet fashion in a dovetail slot of a female half part.

The female half part of connector 170 is best shown I in FIG. 5 as comprising a plate 175 suitable for securea tight, snug interlock being insured by the mere weight of the subassemblies themselves.

It is to be understood that the invention is not to be considered as limited to the aforedescribed wedge type of locking device. A keyhole slot and stud arrangement or other equivalent locking means may be employed with equal facility.

In the case of a regular crib, it is normal to decorate only the footboard, such decorating representing expense, and because it is not known in advance which side is going to be placed against a wall and/or how the footboard will be advantageously facing forwardly, it is also normal to locate the drop side capability on each of the two sides.

Herein, however, one of the sides can be forward as a stationary side, that is without the employment of drop side slide rods 142, the

cross rails

132 and 134 being secured directly to the supplemental rails at opposite ends. The sides being interchangeable with each other, the stationary side can be located either on the port or starboard side as desired and the movable side being located on the opposite side according to the individual desires of the owner.

Such arrangement offers the additional salient features, first, that the arrangement of stationary side adds rigidity to the crib (the cross rails being secured directly to the supplemental rails) and, second, that certain of the hardware is eliminated and certain of the decorations are eliminated as well.

It is further to be mentioned that on conventional cribs, there is a clearance between bracket 64 and drop side slide rod 42 sufficient to allow the free passage of lugs 62 from one level to another in the raising or lowering of the spring means and mattress.

Preferentially, in the case of the invention, connecting means 170 is of a special dimension widthwise so as to allow such a spacing between end rail 112 and adjacent supplemental end rail 138 as to permit easy clearance of lugs 162 between bracket 164 and end rail 112 as the spring means and mattress are raised and/or lowered.

A further advantage in mounting the suspension brackets on the supplemental end rails 138 is that the full weight of the occupant child is then thrust upon the sides of the crib thereby adding to the effectiveness of the wedge lock while at the same time achieving a hiding of the hardware behind the wood so as to maintain same hidden from a curious child.

As an additional important feature of the invention, federal government regulations now dictate the parts held together by screws and requiring removal for disassembly purposes must be machine'screws with machine grommets, adding appreciably to the basic costs.

ln the case of the crib hereof, no nuts or bolts or screws are required to be removed for purposes of dis assembly so as to eliminate the need for any machine screws or grommets in the entirety of the construction, therefore allowing use of wood screws with attendant economics.

The invention further envisions a system which includes the provision of a two-part headboard subassembly or of a two-part footboard subassembly, as desired, wherein the upper or the lower of the parts thereof may be removed, to provide a foreshortened footboard of a youth bed, to the end that the child who has outgrown the crib may be readily provided with a youth bed having the appearance of a conventional adult bed incorporating the more acceptable higher headboard and lower footboard subassemblies.

Crib manufacturers conventionally produce a crib incorporating a headboard (normally positioned adjacent a wall) having a three-fourths panel", so described as a result of having a pair of relatively long supporting legs with a shorter panel, and a footboard (normally positioned inwardly of the said wall) having a full-length" panel, so described as a result of having a pair of shorter supporting legs and a larger panel.

Cribs being normally viewed from the front or foot, the

long legs of the headboard are usually not observable. The generally observable effect is one of a bedstead wherein the opposite end panels are seemingly of substantially equal height with the topmost horizontal planes of those end subassemblies and of the interconnecting drop sides on the opposite sides being coplanar.

Preferentially, but not obligatorily, the relatively long legs representing the lower portion of a crib headboard are removable to allow a shorter or lowered end subassembly for adaptation as a footboard of a youth bed.

Nonetheless, the invention, in broadest aspects, com-,

prehends the removal of either the upper or lower portions of either a headboard of footboard of a crib, to allow the lowered appearance of a footboard of a youth bed. When so removed, the converted subassembly is seen to incorporate a full-length subassembly. Herein, l envision use of one of the high subassemblies of the crib and modifying it into a low subassembly, thereby to contribute to the esthetic appearance of a youth bed.

Headboard 110 of FIG. 1 is two-part construction in the respect that vertical end rails 112 are each formed of an upper portion 112 and a lower portion 113 which is releasably secured to said upper portion such as by an upwardly projecting pin or rod. (not shown) having a lower extremity fitted into a suitable opening in the lower portion and an upper extremity projecting upwardly therefrom and being receivable as by a friction fitin a suitable aligned opening in the upper portion, wherefor the parts may be held together and readily separated from each other as disengagement may be desired.

The now lowered or foreshortened headboard subassembly becomes what will serve as the footboard subassembly of the youth bed shown in FIG. 7, same being generally indicated at theleft hand side of the Figure by the same numeral 110, numeral 112 indicating the end rail thereof.

At the same moment, the old footboard subassembly now will serve as the headboard subassembly of the FIG. 7 youth bed with end rail 122 thereof carrying the same numerical designation.

The head panel is now seen to be supported by the foreshortened legs. 7

Spring means is similarly disengaged from its first position on the headboard and is relocated in a second position so that mattress 166, supported by the spring means, is disposed in a horizontal plane.

The vertical height of the lower part of each vertical side rail will correspond to the vertical height of the lower part of each drop side slide rod so that, in the conversion process, the extent of the foreshortening of both sets of components is the same.

So converted, the bedstead may then be turned around so that the former headboard subassembly now serves as the footboard subassembly of the converted bedstead, as shown in H6. 7, all whereby what was formerly a crib now has the appearance and function of a youth bed.

To avoid the need for the customer involving himself with hardware transfers, a new pair of side subassemblies complete with hardware are obtained from the supplier and the crib side subassemblies are disposed of.

.The youth bed side subassembly, generally designated by comprises a horizontally extending configured top cross rail 182 defining a high end, a horizontally-extending intermediate cross rail 184 defining a low end and a horizontally extending bottom cr'ossrail 186, said cross rails being spaced as to each other and interconnected as by vertically spaced slots or spindles 188, the cross rails being mounted directly on supplemental end rails 238.

The salient point is that it is the youth bed side subassembly 180 which mounts its own supplemental end rails 238, each thereof being provided with the corresponding suspension bracket 164 and also half parts of connectors 270, female half parts if the headboard and footboard subassemblies are provided with male half 1, A knockdown crib/youth bed arrangement made from prefabricated subassemblies in the form. of a headboard and footboard and opposite "sides slip jointed together in assembly, the subassembliesbeing formed complete with requisite interconnecting means to the preclusion of loss of such parts by the ultimate consumer, comprisingz' a I a. a pair of spaced end panels each inclusive of a pair of opposite vertically extending end rails;
