Application June 10, 1946, Serial No. 675,528
The present invention relates to supporting means in general and particularly to a new and novel frame constructed and designed as to be capable of performing a plurality of desirable and necessary functions. More specifically the invention comprises a demountable frame constructed and arranged as to function as a childs crib or as a cocktail table.
Children's cribs have formed an inte ral part of the home from the dawn of civilization. The young child requires a special bed in which it can be placed in comfort and in which it will remain With safety. The ordinary adult size bed is not suitable for the very young child as it provides no safeguards to prevent the child from rolling off onto the floor. In the special childs crib, usually made in dimensions only a fraction of those of the full size adult bed, sides are provided of sufficient height to serve as barriers or guards for purpose of safety.
It is the history of the use of childrens cribs however that they gradually pass from the very center of the stage of home life into a state of disuse to find their final abode in some storage closet or attic from which they are recalled only upon the appearance of a new offspring whereupon the cycle is repeated, being always of substantially the same time duration. An economic loss is involved in this type of usage which is greater or lesser in degree and in proportion to the number of children in the family. Being primarily designed for a single purpose, the crib becomes non-utilitarian after it has served that function and remains usually only as a reminder of the past.
With an appreciation of the normal life history of childrens cribs, and with a full awareness of their vital function in the family life, the present invention has been made and provides a construction which embodies all of the functional usefulness and capabilities of the childs crib and in addition thereto other functions and abilities which entirely change the history of its usefulness. According to the present invention, a utilitarian frame is provided which is so constructed and arranged as to form the supporting structure of a childs crib when needed for that purpose. Being constructed of a multiplicity of interrelated and interfitting parts, it is adapted to be disassembled readily and with a minimum of physical labor and converted into a utility table particularly suitable for beverages and foods, a table of the type commonly referred to as a cocktail table. When not needed as a crib, it stands ready to perform this second function and accordingly is continuously useful throughout its entire life instead of being useful only intermittently.
With the foregoing in mind it is an object of the present invention to provide a utilitarian frame suitable as the supporting framework of a childs crib and also as the supporting frame of a cocktail table. It is a further object of the invention to provide a frame for a childs crib formed of a plurality of interfitting parts which are readily assembled and disassembled. It is still a further object of the invention toprovide a childs crib which is convertible into a cocktail table, and vice versa.
These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawings to which they relate.
Referring now to the drawings, in which a preferred embodiment of the invention is illustrated:
Figure l is a view in perspective of a childs crib constructed in accordance with the present invention;
Figure 2 is a transverse vertical section through the crib shown in Figure 1;
Figure 3 is a vertical longitudinal section through the framework comprising the present invention;
Figure 4 is a bracket element by which the framework is secured to an adult bed;
Figure 5 is a longitudinal section through one of the joints, being taken upon the line 55 of Figure 1;
Figure 6 is a perspective view of the present invention converted into a cocktail table;
Figure '7 is a transverse section upon the line 'i'! of Figure 6;
Figure 8 is a partial side view looking in the direction of the arrows upon the line 8-8 of Figure 7.
Referring again to the drawings and to Figures 1 to 5, inclusive, the frame constructed in accordance with the present invention is disclosed embodied in a childs crib. The frame proper is seen to comprise four main U-shaped body members ll, 12, I3 and M which are preferably metallic, tubular and exteriorly finished as to provide a pleasing appearance. Members H and E2 are the side floor-contacting members and each includes an elongated horizontal extension I la. which rests upon the floor and from the ends of which extend upright sections or legs I lb connected thereto by gently curved corners llc. Side member I2 is a duplicate of member II in each detail. The
upper ends of the vertical portions IIb and I2!) are slightly enlarged to form irregularly sectioned, preferably hexagonal, receptacles or sockets lid and H11.
Spaced lower body members I I and I2 are seen to be parallel and to have their vertical elements IIb and IE1) connected by the upper body frame members I3 and I4, which, in a manner similar to members II and I2, are provided with horizontal and vertical portions I3a, I la, and I31), Mb, respectively. The lower extremities of the vertical legs I31) and Mb of members I3 and I4 are enlarged and given an irregular section to form sockets I3d and Md, respectively, and into each is fixed, as by being pressed or welded, a similarly sectioned projecting pin IS the lower end I6a of which is cylindrical and of a size to fit snugly in the vertical legs of the lower U-shaped frame member positioned thereunder and into which it extends for some distance.
A pair of vertically spaced straight tubular side members I? and I8 extend upon opposite sides of the frame between the vertical legs of the U-shaped frame members. These side members are flattened at their ends, in the manner shown at I'Ia in Figure 5, so as to extend through a slot formed in each vertical leg of the principal frame members. This slot is indicated at I I6 in Figure 5 for frames member I I and is exemplary. The height of flattened portion I'Ia is such as to enable it to be inserted through the slot I Ie so that a notch IIb on its underside can seat the leg wall to effectively lock member I'I against lateral displacement in the absence of a vertical displacing force. Each of the lower side members II also performs a joint locking function and in the following manner. The lower cylindrical end IBa of each joint pin I6 extends below slot He and is itself provided with a transverse channel or slot I61) into which the flattened portion IIa extends. The pin cannot be displaced vertically until the side member II has been displaced and this provides an interlockin relationship which prevents theupper and lower main frame members being The upper tubular side elements I8 are also provided with flattened ends Iiia and extend through e slots in members I3 and I4 at its opposite ends. They connect between the downwardly-extending legs of upper main frame members E3 and I4 in the identical manner that members I? connect the upwardly extending legs of lower main frame members II and I2. The only difference lies in the fact that members I8 perform no joint locking function as do members I'I. Members I8 are also of such length that with the members I? in place, the notches I8b seat tightly in the manner previously described in connection with the notches Ill). The members I! and I8 upon the opposite sides of the frame are positioned above and below the joints, and
are separated vertically by a distance which is suitable for the depth of the bed portion of a childs crib or bassinet.
The framework proper also includes horizontally extending tubular end members I9 provided,
in the manner of members I I and I8, with flattened end portions I9a and which seat in the opposed and parallel vertical leg portions of the lower frame members II and I2 in the manner previously discussed in connection with the side horizontal elements I! and I8. Members I9 are positioned vertically substantially midway between members I1 and the supporting surface and complement horizontal portions I3a and Ida 0f the top main frame members in giving transverse rigidity to the frame.
The frame which has now been described is adapted for use as an integral part of a childs crib or as the supporting base or framework of a cocktail table. Its use as a crib or bassinet is illustrated in Figures 1 and 2, in which the frame assembled as described carries an open topped fiat sided and fiat bottomed box-like receptacle 2|. The side walls of this receptacle are indicated by the reference character 22, the end walls by the reference character 23, and the bottom by the character 24. Open hems or sleeves 26 extend along the upper and lower edges of side walls 22 and seat the horizontal side elements I! and I8. In assembling, elements I1 and I8 are inserted through the sleeves 26 prior to being con- "nected' into the framework and when finally incorporated therein are so positioned as to draw taut the sides, ends and bottom walls of the receptacle in the manner shown in Figures 1 and 2. The receptacle 2I may be made of any suitable material, a strong cloth such as canvas being suitable, or even of sheet metal if desired.
It is often desirable that the crib be retained in close proximity to the bed of the parent and to aid in securing it in such a position a bracket 28, such as that illustrated in Figure l, is pro Vided. Bracket 28 includes a lower split cylindrical portion 29 and an upward extension 3i turned over at its end to form a hool-z The bracket is adapted to be positioned, as shown in Figure 1, upon one of the vertical legs, as for example I21), and immediately below the transverse end member I9. When so positioned the upper hooked end 32 is adapted to extend over the side rail of the bed where it functions to fix the position of the bed and the crib.
The frame constructed, as stated, is also adapted for use as the sup-porting structure of a combination food and drink or cocktail table. When so used, the receptacle 2i is entirely omitted and between the horizontal side menber I1 and I8 are positioned a plurality of trays 33, each of which comprises a flat base 3 at the ends-of which are positioned handle elements 36, including spaced bolts 3's so positioned as to extend immediately outside and adjacent to the supporting elements II or IS. The lower end of each bolt 31' carries an abutment ring 35' which is preferably of a non-abrasive material such as rubber and which is so positioned as to contact the side of its supporting element I? or I8 to eliminate entirely all danger of accidental transverse displacement. In a preferred arrangement three trays 33 are supported upon the upper side members I1 and an additional three trays upon the lower members I8. At a still lower level and between the end members I9, a single elongated tray II is mounted. Element 4| may well be made of a single piece of metal or plastic, of a length as to fit between the elements I9, and of a width slightly less than the width of the frame proper. Its base 42 is formed with slightly hooked ends or handles 43 which rest upon elements 19 to provide a secure support.
When supporting the trays 33 and 4| as illustrated in Figure 6, 7 and 8, the construction is an acceptable article of household furniture performing a desirable function. When functioning as a childs crib, as shown in Figures 1, 2 and 3, it is as suitable as constructions having no other capabilities. Being formed of a plurality of interengaging parts it is readily assembled and disassembled and without the use of tools. The crib receptacle is easily removed and replaced by a fresh receptacle, a feature of importance particularly when the unit is used as standard hotel equipment. The entire frame may be made of a polished metal, coated, sprayed, painted or varnished as desired, and the coopcrating and removable trays may be artistically designed and colored to present a most pleasing appearance.
While the particular apparatus herein shown and described in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the details of construction or design herein shown other than as defined in the appended claims.
