HAMMOCK CRADLE Filed April 2. 1964 INVENTOR Robert J. Roberts ATTORNEY United States Patent 3,203,012 HAMMOCK CRADLE Robert J. Roberts, 351 Hamilton Place, West Islip, N.Y. Filed Apr. 2, 1964, Ser. No. 356,817 3 Claims. (Cl. -120) This invention relates generally to collapsible hammocks of portable character and which may be conveniently stored when not in use, and more particularly to a hammock of improved construction wherein the cradle thereof may be utilized apart from the hammock as a basket adapted to carrying an infant or packages therein.

Whereas living space in apartments and private dwellings as well, is often limited, duality of purpose of household objects is a sought after desideratum mainly in view of the space saving attribute realisable therefrom. Other conveniences, however, will often be appreciated where a single object may be put to more than one purpose.

Specifically, and consonant with the foregoing, the instant invention has for an object the provision of a hammock, wherein the cradle adapted to swing between the end standards thereof may be readily removed and hand-carried as a basket while shopping or used as a portable crib for carrying an infant in an automobile, for example.

Another object of the present invention is to provide a device of the foregoing character wherein the cradle, whether when utilized in combination with the hammock or as a basket independently thereof, will be carried by support members interchangeably applicable for either purpose.

A further object of this invention resides in the provision of a hammock cradle which may be removed from the hammock merely by raising the cradle oif the support members, said cradle being seatingly suspended therebetween.

Another object of the present invention is to provide a device in accordance with the foregoing which includes helical spring suspensions for the cradle while in the hammock embodiment and which affords collapsibility with respect to the hammock standards and frame structure to facilitate storage thereof.

Another general object of the present invention is to provide a device of the described character which will be simple in structure, economical of manufacture, easily and quickly assembled and highly effective in use.

Other objects and advantages of the instant hammock cradle will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice of the invention, the same being realised and attained by means of thestructure defined and pointed out in the appended claims.

The accompanying drawings referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

FIGURE 1 is a perspective view of the hammock cradle suspendedly supported intermediate the end standards of the hammock structure;

FIGURE 2 is an end elevational view of the cradle including one end of the hammock structure and cradle support means;

FIGURE 3 is a side view of the cradle apart from the hammock structure, the support members being connected therewith to provide handles for carrying said cradle;

FIGURE 4 is a cross-sectional end elevation of the cradle taken along line 44 of FIGURE 3; and

FIGURE 5 is an enlarged and fragmentary view of the connecting means including helical coil spring and cylindrical socket member.

Referring now in detail to the present preferred em- Biddfili Patented Aug. 31, 1965 bodiment of the invention illustrated in the accompanying drawings, FIGURE 1 shows the cradle designated generally by numeral 1 operatively suspended intermediate spaced, opposingly positioned standards 2 and 4.

More specifically, the cradle structure is comprised of a hollow shell having an open top 6,

side walls

8 and 10, end walls 12 and 14 and bottom wall 16, said end and side walls having top edges 18 which define the periphery of the open top 6 of said hollow shell. It will be appreciated that although the cradle described is preferable, other suitable constructions may be employed, such as a barred or perforated structure defining an opening therewithin for carrying an infant or packages if desired.

Elongated

arcuate hook members

20 and 22 intergral with

said side walls

8 and 10, respectively, and disposed adjacently of the top edges thereof, each extend horizontally and outwardly from said side walls and turn downwardly therefrom as shown in the drawings.

With reference again to FIGURE 1, respective pairs of

ears

24, 26 and 28, 30, will be observed projecting upwardly of the top edge of

side walls

8 and 10, respectively, a socket passage 32 being disposed through each said ears. Upon viewing the several figures collectively, it will be appreciated that the passage disposed through each respective ear associated with one side wall is in axial alignment with the passage disposed through respective ears of the other side wall, i.e., the passages through ears 24 and 28 are axially aligned and similarly with respect to the passages through

ears

26 and 30. Accordingly, said pairs of cars as shown are arranged in spaced relation, said hook members, respectively, being disposed intermediately therebetween, said hook members being substantially equidistant with respect to said end walls 12 and 14.

It will be understood that while said hook members and socket passages are preferably provided as herein disclosed and described, other suitable embodiments are considered within the purview of this invention. For example, said socket passages may be disposed directly through

side walls

8 and 10 rather than through

ears

24, 26, 28, and 30, which in such event, the latter may be dispensed with; and hook

members

20 and 22 may vary in configuration, without materially modifying the operability of the invention.

To the ends of supporting the cradle as shown in FIGURE 1 or of providing carrying handles therefor as shown in FIGURES 3 and 4, U-shaped

support members

34 and 36 are provided, each being formed of divergingly arranged free-

ended arms

38, 40 and 42, 44, respectively, and horizontal

apical sections

46, 46 disposed between said arms of each support member as shown in FIGURE 3 of the drawings.

Sleeves

48, 48, each being coaxially and rotatably disposed about said apical sections, respectively, provide convenient handle grips upon utilization of said support members as shown in FIGURES 3 and 4 and further constitute bearing supports between said sleeves and hook members when said cradle is suspended as shown in FIGURES 1 and Q.

Laterally extending bent portion 50 is provided terminally of the free end of each said free-ended arm, as shown in the drawings, and is removably receivable within a socket passage 32 of said respective ear project-ions, thus rendering

support members

34 and 36, in their inverted position as shown in FIGURES 3 and 4, effective carrying handles for hammock cradle 1, to thereby enable utilization of said cradle as a shopping basket or as a portable crib as the demand may be.

With respect to the hammock structure in particular, it will be seen that each said end standard 2 and 4 is comprised of

leg elements

52, 54 and 56, 58, respectively, each leg element being pivotally connected by pins 60 to s,aos,012

thereof being shown in FIGURE with respect to leg element 52, the pairs of leg elements may be folded into mutual juxtaposition, side braces 64 being provided as a rigid connection between said end standards thereby maintaining said standards in spaced relation whether they be folded for storage or operably arranged.

Each cradle connecting means shown secured at the upper end of each standard 2 and 4 in FIGURE 1 of the drawings and generally designated by numeral 68 in FIG- URE 5 includes helically coiled tension spring 70, one end 72 thereof being securely hooked into eyelet 74 connected approximately centrally of cross member 62, the other end 76 thereof being secured through cylindrical socket member 78 by nut 79, bores 86 being disposed inwardly of the ends 82 of said socket members, wherein bent portions 50 of said support members are receivable. Set screws 84 are employed for securing said bent portions within said bores. Accordingly, with the secure retention of bent portions 5% Within bores 3-9, a secure and resilient suspension system comprised of

support members

34 and 36 and said cradle connecting means is provided intermediate said end standards. Further stability to the instant hammock structure is provided by flexible restraint means 84 connected intermediate the lower ends of each pair of leg elements, thus limiting the relative movement of said elements.

Thus, where the cradle is to be used with the hammock structure, hook members and 22 are merely seated upon the sleeve 48 of respective horizontal apical sections, suspension of said cradle between the standards of the hammock being thereby eftectuated. Where the cradle is to be used as a carrying basket or portable infant crib, bent portions of

support members

34 and 36 are removed from socket members '78 and after inversion of said support members as shown in FIGURES 3 and 4, the bent portions are inserted into socket passages 32 of said ear projections. The crib or basket may conveniently be carried at sleeves 48 which now serve as handles.

Although the preferred embodiment of the hammock cradle has been described, it will be understood that within the purview of this invention various changes may be made in the forms, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consists in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
