Abstract
A baby hammock should be washable. Therefore, any non-washable components should be easily removable from the washable components. The reassembly of the components should be simple. For this purpose the present hammock has longitudinal, open ended pockets or channels extending along the upper edges of the side panels and of the end panels of the hammock body. Wooden rods, also referred to as dowels, are inserted into these pockets. The ends of the rods overlap at each corner of the hammock body. Ropes interconnect the overlapping rod ends and simultaneously serve as suspension elements. The ropes extend through one or several rings at the upper rope ends. The lower rope ends pass through and around the rod ends and are tied for a safe connection. The tying is easily untied for removing the rods.

Description
Background of the Invention
The present invention relates to a hammock, especially a baby hammock of the type which may be suspended, for example, from the ceiling, and which is versatile in its use, yet simple in its construction.
Baby hammocks have been manufactured heretofore, whereby three basic hammock types appear to exist. The first hammock type employs hinged metal components forming a frame. Due to the hinges it is possible to fold the hammock into a smaller shape for storage or transportation. The second type of hammock may also be assembled and disassembled and folded into a smaller shape. For this purpose the second type employs a multi-component frame structure of rods and tubular members, whereby the rod ends are inserted into the open ends of the tubular members substantially in a telescoping manner with additional means for locking the frame components into a fixed position relative to each other once the frame is assembled. The third type of hammock minimizes the use of frame components and such frame components, if used, are tied together by pieces or cord or rope or held by rivets or screws.
U.S. Pat. No. 2,636,190 is considered to be representative of hammocks having a metal frame with foldable hinges. The hammock body is made of fabric and the upwardly open edges of the hammock body have flaps which are foldable around the metal frame components. Snap fasteners are used for securing the flaps to the hammock body once the flaps are folded around the metal frame parts. This type of structure leaves room for improvement because the metal frame is rather expensive and because the hammock body is actually not machine washable even though it can be removed from the metal frame.
U.S. Pat. No. 1,376,476 is considered to be representative of structures in which the frame components comprise rods and tubular members into which the free ends of the rods are inserted. The rods and tubular members are provided with interlocking elements to avoid an inadvertent separation of a rod from a tubular member. The frame structure in U.S. Pat. No. 1,376,476 is arranged so as to extend out of and away from the hammock body proper so that the child resting in the hammock cannot touch the frame. This known structure is supposed to be foldable, but it is doubtful whether it can be easily assembled and disassembled. Similar considerations apply to all other prior art structures falling into this group.
The third group which avoids using frame members is represented by U.S. Pat. No. 1,237,628. This reference discloses a hammock sewn together in the manner of a bag with a open side and without any stiffening components other than the supporting straps. U.S. Pat. Nos. 2,467,890 and 1,225,208 also fall into this group, however, with the exception that stiffening members are used. Such stiffening members do not form an interconnected frame structure.
U.S. Pat. Nos. 595,235 and 962,092 show an approach which minimizes the use of frame components, thus, in U.S. Pat. No. 595,235 four rods are interconnected at the corners by rivets or bolts and two of the rods are hinged intermediate the ends for folding. The suspending ropes are tied to the bars. For this purpose the lower ends of the ropes extend through separate holes in the bars. Thus, these ropes serve merely for the suspension purpose. The structure of U.S. Pat. No. 962,092 is quite similar to that of U.S. Pat. No. 595,235 except that the slats or rods are not hinged intermediate the ends. The slats or rods are interconnected at the corners by a piece of rope which is separate from the suspension ropes. The piece of rope which interconnects the slats is made long enough so as to permit a certain hinging movement of the end slats or bars between a hammock suspending position and a non-use position. Here again the suspending ropes serve only for the suspending purpose.
Objects of the Invention
In view of the above it is the aim of the invention to achieve the following objects singly or in combination:
to construct a hammock, especially a baby hammock, in which any washable parts, such as the hammock body, are easily and quickly assembled with or disassembled from any non-washable parts;
to arrange the components of a hammock in such a manner that it may be rolled up for storage or transportation;
to construct a hammock substantially without any metal parts, especially without any metal frame components;
to suspend a hammock selectively from one or two hooks;
to construct a hammock so that it may be used as a carrying case for a baby; and
to construct a hammock so that it may be assembled and disassembled by tying or untying knots only, whereby the suspending ropes simultaneously serve for two purposes, namely the suspending and for holding wooden frame members together.
Summary of the Invention
The hammock according to the invention comprises a hammock body with four corners. The hammock body is made of a washable material such as a fabric and has two longitudinal side panels, two end panels, and a bottom. Each panel has an upper edge and rod holding means secured to each upper edge. Two stiff longitudinal rods are operatively held by the respective rod holding means of the longitudinal panels. Two stiff end rods are operatively held by the respective rod holding means of the end panels. The stiff longitudinal rods and the stiff end rods have such a length that the rod ends overlap at each of the four corners of the hammock body. Four rope means interconnect the respective overlapping rod ends at each of the four corners and the same rope means simultaneously suspend the hammock, whereby each rope means performs simultaneously two functions, namely, a rod connecting function and a hammock suspending function.
The advantages of the present hammock are seen in that by simply untying a few knots the non-washable rods may be withdrawn from the pockets of the hammock forming panels which are then machine washable. The assembly is similarly easy by inserting the rods, for example, in the form of dowels into the open ended pockets and retying the knots. Another advantage is seen in that by simply reducing the length of the suspending ropes the present hammock may be used as a carrying case, whereby the ropes perform yet a third function while still permitting the end bars or rods to keep the hammock from folding up. Further, the present hammock is very simple because it avoids hingeable and foldable metal frame components, whereby the manufacture of the hammock is also greatly simplified so that it may be made by using simple hand tools and a sewing machine.

Detailed Description of Preferred Example Embodiments and of the Best Mode of the Invention
FIG. 1 shows the hammock 1 comprising a hammock body with four corners. The hammock body is made of washable material for example, canvas or any other suitable fabric. The hammock body has longitudinal side panels 2, end panels 3, and a bottom. Rod holding means 4 such as open ended pockets 4 or loops are secured to each upper edge of the side and end panels. These open ended pockets 4 may be formed, for example, by folding over a portion of the respective panel along the upper edge thereof and providing one or several rows of stitches 24 as shown in FIG. 4.
Two longitudinal, stiff rods such as wooden dowels 5 are inserted into the open ended pockets 4 of the side panels 2. Two shorter, stiff end rods such as wooden dowels 6 are inserted into the open ended pockets 4 of the end panels 3. The length of these dowels 5 and 6 is such that they overlap at the corners as shown in FIG. 1. Four rope means 7 or sets of ropes are used according to the invention to perform the function of suspending the hammock from an overhead fixed point and for interconnecting the overlapping rod ends as will be described below in more detail. Four single ropes may be used to form the set of ropes 7. However, it is preferable to use a plurality of ropes as shown in FIG. 2. Each rope may be provided with decorations such as wooden beads 8. The rope ends extend through openings in each rod end and knots 10, 11 are provided for interconnecting the rod ends and for securing the ropes to the rod ends. Additional safety means 9 may extend through the rod ends to prevent the ropes from slipping out of an opening at the rod end if the opening is an axial slot.
As shown in FIG. 2 it is preferable that the suspending rope means 7 comprise four groups of ropes formed by using eight lengths of rope in pairs of cords doubled back intermediate the ends thereof to form a noose 13 through which a ring 12 extends. Each doubled back pair of cords provides four rope ends 14, 15, 16, and 17. Four of these free rope ends 14, 15, 16, 17 are used in each corner construction as will now be described with reference to FIGS. 4, 5, and 6. The upper edges of the longitudinal side panels 2 extend to a level lower than the level of the upper edges of the end panel 3, whereby the stiff end rods 6 extend above the stiff longitudinal rods 5. The rope ends 15 and 16 extend through a clothespin type of notch 18 in the rod or dowel 6 and the rope ends 14 and 17 extend through the grooves 19, whereby the rope ends are held in place. A peg 20 shown in FIG. 5 may be used as a safety means 9. Such a peg may also be replaced by a stove bolt 21 as shown in FIG. 4.
The rope ends 15 and 16 further extend through a hole 23 in the end of the longitudinal dowel 5 and the rope ends 14 and 17 may further extend through notches 22 as best seen in FIG. 6. One or several knots 11 may be provided below the end dowel 6. Such knots are shown symbolically in FIG. 4. However, knots of the type shown in FIGS. 3 or 7 may be used for this purpose. One or several knots 10 also shown symbolically in FIG. 4 will further be provided below the dowel 5, whereby again knots of the type shown in FIGS. 3 and 7 may be used. Other knot types may also be suitable.
Due to the grooves 19 in FIG. 5 or 22 in FIG. 6, the ropes are already held in place, especially when the knots 10 and 11 are tied closely to the respective dowel 5 or 6. However, for safety purposes it is advisable to use a peg 20 when the dowels are provided with clothespin type notches 18. All the dowels 5 and 6 may be provided with clothespin type notches at both ends or all dowels may be provided with holes and grooves as shown in FIG. 6
As shown, the lower dowels 5 are provided with holes 23 and grooves 22, whereas the upper end dowels 6 are provided with notches 18, however, the invention is not limited to this combination.
Further, although round dowels have been illustrated, the invention may also be practiced by using, for example, square or rectangular dowels. Making the end panel 3 somewhat higher has the advantage that, for example, a cushion may conveniently rest against one of the end panels. However, again the invention is not limited to this arrangement of the end panels. It is quite possible to let the side panels 2 extend above the end panels 3.
In the light of the above disclosure it will be appreciated that it is very simple to assemble and disassemble the present hammock without any tools because a stop member such as the peg 20 or a bolt 21 may be removed by hand since the peg is inserted with a very light press fit.
Although the invention has been described with reference to specific example embodiments, it will be appreciated that it is intended to cover all modifications and equivalents within the scope of the appended claims.
