BACKGROUND
The embodiments described herein relate to a portable hammock frame and hammock bed capable of transforming into a sofa.
Hammock beds have existed for a long time but require two existing pillars or poles (such as trees or posts) to be tied to, to set up the hammock bed. In order to circumvent the lack of availability of the pillars, frames simulating these pillars have also been created.
Existing frame designs are typically not portable and must practically be restricted to certain locations. It has been a challenge to take a hammock bed with you to locations where pillars do not exist. Furthermore, transporting hammock frames can be cumbersome. As an example, a portable hammock bed would be desirable to use at a beach or park where it can be packed up for portable transportation, easily deployed during use, and easily repackaged for transportation back home.
It is desirable to have a portable hammock bed design for easy transportation.
SUMMARY
In a preferred embodiment, a hammock frame bed is provided. The frame is light and foldable, and portable. This allows it to be taken to many different environments and provides a self-sufficient structure to enjoy a hammock once unfolded into its final shape from its folded, portable configuration. Furthermore, its unique design makes it particularly light and capable of supporting a high load (e.g., up to 250 kg), therefore allowing more than one person to utilize it at the same time.
On average, the typical hammock bed provides very little flexibility in terms of configuration. An ideal bed would be one that can also be configured into a couch, which allows users not only to lie in a bed configuration, but also sit in a comfortable sofa configuration, where the sagging is now minimized, and they have a more natural sofa position.

DETAILED DESCRIPTION
In a preferred embodiment, a hammock suspension structure (HSS) with a hammock bed convertible (HBC) is disclosed. According to the preferred embodiment, the hammock suspension structure (HSS) consists of a light, foldable and portable frame. This allows it to be taken to many different environments and provides a self-sufficient structure to enjoy a hammock once unfolded into its final shape from its folded, portable configuration. Furthermore, its unique design makes it particularly light and capable of supporting a high load (e.g., up to 250 kg), therefore allowing more than one person to utilize it at the same time. The Hammock Bed Convertible (HBC) further increases the utility of hammock structure by providing a multitude of configurations that can be taken to multiple environments and accommodate multiple people.
FIG. 1A is an illustration showing an exemplary hammock bed design. According to FIG. 1A, there exists two solid structures of one type or another that the hammock can be attached to. A hammock is connected to both ends.
FIG. 1B is an illustration showing a typical hammock bed design. According to FIG. 1B, there exist two hammock poles or suspension bars and a plurality of middle bars. The middle bars are placed parallel to the floor (e.g., a flat surface) and joined by connectors. The end folding middle bars are connected to the hammock poles (suspension bars) and are connected at an obtuse angle (greater than 90 degrees). A hammock bed is connected to both ends of the hammock poles and can swing side to side in that suspension. The hammock can be made of cotton, bamboo, polyester, wool, and other suitable fabric material.
FIG. 1C is a render illustrating the design of the first component of a Hammock Suspension Structure (HSS). FIG. 1C illustrates the frame for the HSS design. Dimensions of an exemplary HSS can vary greatly. In this preferred embodiment, they stretch approximately 300 cm (length, from the top of one vertical pole to another)×approximately 180 cm (width)×approximately 100 cm (height) and can support up to a weight of around 250 kg (550 lbs.) according to materials used in construction. Again, various materials and dimensions are possible within the confines of the design.
FIG. 2 is a render illustrating the top view of the frame of an HSS design. In a preferred embodiment, the suspension bars (poles) are angled at approximately 105 degrees away from the middle bar at a height of about 100 cm, and a total suspension distance of about 300 cm. In a preferred embodiment, there are 5 folding horizontal bars, and 2 folding vertical bars. However, other embodiments may have more or fewer folding bars with a characteristic creation of a “Z” design.
FIG. 3A is a line diagram illustrating the frame of the HSS with multiple segments. According to FIG. 3A, there are 3 main areas of complexity, which are further shown in Detail in FIG. 3B, FIG. 3C, FIG. 3D, FIG. 3E, FIG. 3F, FIG. 3G, and FIG. 3H respectively.
FIG. 3A further illustrates long rods 1 and 2 and short rods 3 are made of bamboo, preferably Moso cane, but other materials such as plastic, aluminum, steel, and carbon fiber will be considered. Long rods 1 are connected to long rods 2 by means of angled hinge A at each end. Angled hinge A is preferably made of carbon fiber, though other materials may be considered. Long rods 2 are connected to short rods 3 by means of another angled hinge A at each end. Short rods 3 are connected to each other by means of two straight hinges B. Long rods 1 contain a cable mechanism C. The following figures explore areas A, B, and C in detail.
FIG. 3B is a render illustrating Detail A of the HSS as seen in FIG. 3A. According to FIG. 3B, Detail A, consists of an angled hinge, itself composed of angled_hinge_top 3 and angled_hinge_bottom 4. When the user unfolds the rods 9, hinges 3 and 4 pivot around the angled_hinge_pin 6. At that point the angled_hinge_spring 2, housed in the angled_hinge_housing 1, pushes the square_lock_peg 5 into the square hole on the side of hinge 4, locking it into place, and preventing the hinge from folding back down. When the user wishes to fold everything back, they push the push_release_button 7 (kept in place by the push_release_button_cover 8) inwards, thereby pushing peg 5 back inside, away from the square hole, and allowing the hinge to fold back in, along with the rods connected to it. In this embodiment, all the above-mentioned parts are made of carbon fiber, except for the pin 6 and the spring 2, which would be made of stainless steel, titanium, or aluminum. In other embodiments, carbon fiber can be replaced (for some or all parts) with any other suitable material, such as hard plastic, titanium, or any material with right properties.
FIG. 3C is a set of line diagrams further illustrating the constituent parts of Detail A as seen in FIG. 3A.
FIG. 3D is a render illustrating Detail B of the HSS as seen in FIG. 3A. According to FIG. 3D, Detail B consists of straight_hinge_half_large 4 and a straight_hinge_half_small 6, connected to short rods 1. When unfolded, the straight_hinge_spring 5 pushes the straight_hinge_piston 7 into the cavity inside hinge 6, thereby rigidly situating itself between hinges 4 and 6, and locking them in place in the unfolded position. When the user wishes to fold everything back up, they pull back the straight_hinge_screw 3 (which is connected through a groove on hinge 4 to piston 7), pulling piston 7 back into its housing in hinge 4, and allowing hinges 4 and 6 to fold back up. Furthermore, hinges 4 and 6 are connected to short rod 1 with ring connector 2.
In a preferred embodiment, Detail B will be made of carbon fiber (except for screw 3 and spring 5, which will be made of stainless steel), although any suitable material may be considered for any of the above-mentioned parts.
FIG. 3E is a set of line diagrams further illustrating the constituent parts of Detail B as seen in FIG. 3A.
FIG. 3F is a render illustrating Detail C of the HSS as seen in FIG. 3A. The HBC (or any hammock) is suspended on the HSS through a cable system. The cable 3 connects at one end to a standard carabiner 2 and on the other end to the bottom of the vertical angled hinge bulb 4 (which is knotted below it or otherwise restricted). In the middle of all of this, it goes through the cap 1 in such a way (described in following points) to redistribute the forces (gravity pulling down the HBC, and consequently pulling on the long rods) in a manner reorienting said forces to be more parallel to the orientation of the long rods. How this is accomplished is described below. The top cap 1 can be made of carbon fiber or hard plastic. The cable 3 can be made of steel, or high-load natural or synthetic fiber.
FIG. 3G is an illustration showcasing the basic design of the top cap, first described in FIG. 3F. The cap is specifically designed to redistribute forces along the vertical axis and in a manner that corresponds to the vertical rod's strongest plane (parallel to it). To achieve this, a groove is created at the cap's top to direct the cable coming from the hammock bed onto a specific path around the cap. In total there are 3 plates that redirect the cable. The top plate 1 directs the cable coming from the hammock bed, the middle plate 2 reverses the cable's orientation and the bottom plate 3 determines where the cable leaves the cap (in the orientation of the long rod, and toward the bottom).
FIG. 3H showcases the process of wrapping the cable along the cap's circumference in 2 opposing directions which helps redistribute forces more equally. Furthermore, it allows the user to determine how tight (high) or loose (low) the HBC should be suspended between the poles of the HSS, based on their preference. This is done by simply wrapping the cable around the top half of the cap more times (for tight) or fewer times (for loose).
FIG. 4 is a set of renders showing the main skeleton of the HSS with its short and long rods. FIG. 4 also shows the floor pads, which are also first illustrated in FIG. 3D. In a preferred embodiment, they are made of silicon, rubber, or other high friction material, and designed to make contact with the floor and to protect the floor and base from damage, while providing stability and cushioning for the HSS.
FIG. 5A is a diagram illustrating a front view of the dimensions of a hammock frame. According to FIG. 5A, the length of the HSS is 2500 mm (or 2.5 m), without counting the diagonal distance between vertical poles. The long rods have a diameter of 38 mm (0.038 m). The short rods have a diameter of 33 mm (0.033 m). According to FIG. 5A, the material of the middle bars is made of light and flexible material such as bamboo or carbon fiber. The forces on the middle section of the hammock are compressive, such that the middle bars do not bend or flex too much. Furthermore, the middle bars when deployed, may conform to uneven terrains, and would require a certain level of flexibility.
FIG. 5B shows that the width of the HSS is 1820 mm (or 1.82 m). The angle at which the vertical rods incline is 105°.
FIG. 5C shows the total diagonal suspension distance from the top of one vertical rod to the other at 3000 mm (or 3.00 m). As the same hinge is deployed on the ground as the vertical, the angle is also 105°.
FIG. 6A is a set of renders showing the HSS in the fully unfolded position, from varying angles.
FIG. 6B is a set of renders showing the HSS in the semi-folded position, from varying angles. This position allows it to accommodate a smaller ‘chair-type’ hammock.
FIG. 6C is a set of renders showing the HSS in the fully folded position, from varying angles. This is the configuration that allows it to be portable and stored more efficiently.
FIG. 7A is an illustration of the top view of the second component of Hammock Bed Convertible (HBC). According to FIG. 7A, this is a top view of the HBC unfolded, and therefore in the ‘Bed’ configuration. The HBC has basic and familiar components in the ropes 1 and the fabric 3, but additionally, it includes two foldable L-Bars 2. These are crucial in transforming the HBC from the ‘Bed’ configuration to the ‘Sofa’ configuration. The following points will elaborate on that, as well as the structure of the L-Bars.
FIG. 7B is an illustration of the same HBC in perspective. It also shows the buckles of the underside rigid fabric straps (showcased in FIG. 7D). FIG. 7B begins to show how the L-bars 2 can fold/slide down through the ropes 1 to change the shape and orientation of the HBC fabric 3. More details are below.
FIG. 7C is an illustration of the HBC, having been converted into the sofa position. In this process of conversion, the following steps take place:
- a) The 2 outermost ropes 1A on each end of the L-bars (and on both sides of the hammock) are removed from the grooves of the L-bars 2. This allows for their attached fabric 3 to be folded (otherwise the fabric 3 would stretch too high (on the vertical) and be too deep (on the horizontal) to sit on comfortably as a regular sofa and would have a very high back).
- b) The now loose edges of the fabric 3 (with their outermost connecting ropes 1A removed) fold under the remaining fabric 3 and are rethreaded through the L-bar 2 grooves.
- c) The L-bars 2 are pulled/slid along the ropes 1 towards the fabric 3 and rotated 90 degrees along the z-axis (their holes sliding along the ropes), into the vertical (sofa) position.
- d) As the L-bars 2 are sliding into their new vertical position, they snag knots 5 on the now top rope (or top ropes—knots can be strategically placed along them). This shortens the top rope(s) and forces the HBC to swing up from a bed orientation plane into a sofa orientation plane (with back positioned more vertically behind the sitter).
FIG. 7D is an illustration of the bottom side of the HBC showing the underside straps and their buckles 4. They are tied (to either the ropes 1 or the L-bars 2), causing the bottom fabric to tense up, so they don't sag under the sitters. There is a possibility in other embodiments that this part can be replicated on the other half of the HBC to tense up the sofa's “back” as well.
FIG. 7E is an illustration of the two foldable L-bars that allow the ropes for the hammock bed to go through them (or slip out of them through channels if they are not desired i.e., in the cocoon position of the HBC—see FIG. 8C). The L-type configuration, with holes and channels in them 1, allows the bars to slide along the ropes, making two configurations possible: the flat bed configuration and the sofa configuration. Also, the L-Bars' two constituent arms can fold in onto each other 4 to minimize space when not needed (e.g., during transport or storage).
FIG. 7E further shows a possible mechanism of the pivot connecting the two arms of each L-Bar. The overlapping decagon shapes (there are two overlapping decagon rings, one for each arm) on the interior of the hole 2 is the pivot: When you turn one 108° (which is a good angle between the seat of the sofa and its back), it ends up in exactly the same as the starting position. This allows a (also decagon) peg 3 to be plugged into a hole in the top arm and fit perfectly locking the arms. In the closed position of the arms, this peg makes sure they do not pivot open. In their open position, they are locked into position and do not fold. In a preferred embodiment, the length of each arm is approximately 90 cm and is made of aluminum or titanium. However, different dimensions and materials are also possible.
FIG. 8A is an illustration showcasing a configuration of the HSS, with the HBC in flat Bed configuration.
FIG. 8B is an illustration showcasing a configuration of the HSS, with the HBC in Sofa configuration.
FIG. 8C is an illustration showcasing a configuration of the HSS in the fully unfolded position, with the HBC's L-Bars removed, effectively turning the HBC into a regular hammock bed.
FIG. 8D is an illustration showcasing a configuration of the HSS in the semi-folded position, with a chair-style hammock bed suspended on it. The HBC, in another embodiment, could also have a way to fold it in such a way as to shorten its width and allow it to be used in this HSS configuration.
According to this disclosure, the HSS offers a unique shape, which in turn addresses the issues people have had creating a portable hammock. In the current embodiment, the hammock poles of the frame are constructed out of bamboo. This further makes it unique and more environmentally friendly.
According to this disclosure, the HSS design consists of the following unique differences over traditional hammock designs, including the following:
- 1. Traditional hammock designs are similar to bed frames which require pillars or structures to attach to. In the absence of pillars or structures, traditional hammock design cannot be used. The HSS of this embodiment is a portable design that enables the user to carry the frame which obviates the need for pillars or structures and allows the user to set up a hammock virtually anywhere that is reasonably flat.
- 2. Traditional portable hammock design has limits in terms of capacity, size of person it can handle, and comfort. Traditional portable hammock designs may not support two or more people on it. Additionally, there may be a capacity cap out of up to 300 lbs. According to this embodiment, this HSS unfolds into a much larger structure (footprint), thereby allowing for a bigger and more comfortable hammock bed. Furthermore, it also has a capacity of double the weight and may support up to 550 lbs.
- 3. Traditional hammock designs are cumbersome to set up. It may take a few minutes to set up and take apart. According to this embodiment, this HSS can be set up and put away in a few seconds.
The HBC consists of the unique ability to transform into a legitimate sofa-type configuration and back again into a bed.
