Hammocks are widely used for leisure and relaxation. While spending time away from the convenience of modern amenities, hammocks allow people to engage with nature and yet still enjoy a level of comfort or protection from weather and other factors. They generally include a panel made of fabric or netting that is suspended between two points, such as a vertical post or tree. They also come in a variety of different shapes and sizes. For example, some hammocks can be made to function as a bed or tent for camping trips or other sleeping arrangements. Also, some hammocks are collapsible for ease in portability and storage. To further the use and functionality of hammocks, improvements and enhancements of hammocks are desirable.
To further clarify the above and other advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is appreciated that these drawings depict only illustrated embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The following relates to hammocks, particularly inflatable hammocks, and inflatable hammocks that can be used as an inflatable hammock, a sleeping pad, and a chair.
An inflatable hammock comprises a panel that has a plurality or network of fluid interconnected inflatable cells or regions. A plurality of tension members attached on both ends of the panel and having free ends are configured to suspend the panel.
A convertible inflatable hammock comprises a panel with a plurality or network of fluid interconnected inflatable cells or regions. Tension members on both ends of the panel have free ends that are configured to suspend the panel. In one configuration, the hammock is configured for use as a hammock when the panel is supported by the plurality of tension members on both ends of the panel. In another configuration, the hammock is configured for use as a sleeping pad when the plurality of tension members are not being used to suspend the panel.
An inflatable hammock pad comprises a panel with a plurality or network of fluid interconnected inflatable cells or regions provided by the panel. The cells or regions are in fluid communication with each other and provide an air cushioned top surface. A plurality of tension members are attached on both ends of the panel. Free ends of the tension members are configured to be attached to end points or structures and thereby suspend the panel. When the hammock is not being suspended for use, one or more locking structures may be used to confine or otherwise restrict movement of the plurality of tension members. Alternatively, a detachable structure may be used to detach the plurality of tension members from the panel which allows the panel to be used as a sleeping pad.

As shown in
As shown, the panel 102 includes bonded ends, which are an extension of the bonded portions 224 (
One or more tension members 106, or hammock support members are configured to pass through the loops 132 for suspending the hammock. Tension members 106 include elongate elements, such as ropes, straps, tethers, webbing, material used to support the panel 102 under tension when free ends of the tension members are attached to vertical supports or other points. Exemplary tension members as shown include tethers that attach at various points along either end of the panel. Particularly, the tension members pass through the loops and fold around so that both ends of the tension members are secured to vertical supports. The tension members 106 join at endpoints of the outstretched arms. The endpoints of the outstretched arms include a hook. Other types of endpoints include clasps, rings, fasteners, hooks, ties, or other structure of a point for attaching the endpoints of the tension members 106 and thereby suspending the panel 102.
Instead of loops, ends of tension members 106 may be attached to locking structures, ties, hooks, buckles, Velcro®, hook and loop fasteners, carabiners, snaps, or other structures. The loops or locking structures are configured to allow the tension members 106 to be released from the panel. Instead of loops, tension members 106 may attach directly to outer edges of the panel 102 or reinforcement members 123. Variations includes that tension members be attached such that they are not removable from the panel 102.

The configuration of the bonded areas or regions 224 may entail one or more of elongated lines, straight lines, curved lines, jagged lines, or other types of lines. Furthermore, the bonded areas 224 may be any regional space configuration that defines the air containing regions 204. The bonded areas may define air containing regions that are tube-like, round, ball-like, oblong, egg-like, cubed, rectangular, ovoid, triangular, trapezoidal, and/or any number of shapes and sizes. The air containing regions may also being the form of a lattice pattern, a grill pattern, or any suitable repeating or random pattern. A pattern for the air containing regions may be random, or comprise similar repeating but different shapes. The configuration for the bonded areas and air containing regions may also be defined by a pattern to provide an omni-directional or a directional stiffness or other support property to a region of the panel. For example, it may be desirable to increase stiffness in a back support area, or to allow easier bending in a particular direction, such as at sides or a seat of hammock. The air containing area 204 formed by the bonded areas 224 may define a pattern with parallel lines or some other symmetrical pattern. The pattern shown is a symmetrical array formed by a crisscross pattern. Patterns of the bonded regions may have lines that are parallel or angled relative to an axis of the panel, and may contain patterns forming lines, squares, hexagonal shapes, staggered, shapes, or other suitable shapes. Lines may be curved, straight or defined in other ways.
Structures that function equivalently to the two-ply bonded construction are contemplated, such as, a single-ply material with air cells bonded to it, with communication of the air cells.
The panel may be any shape, including circular, rectangular, triangular, oval, and other shapes. Contours and Rounded edges may be added to provide certain stability and comfort as desired. For example, as shown in
The air containing region 204 includes a hollow space or fill volume as defined between the top 220 and bottom substrates 222 being bonded together or attached by structure. The bonded 224 regions and other regions have no fill volume or less of a fill volume. When used as a pad, at least a portion of the cells are configured to provide support to a user and elevate the user above a ground surface. Certain regions may be in the form of cells that have a greater fill volume than other cells to provide a primary support to target regions of the user, such as the hips and shoulders, or other body regions. Secondary support regions with less fill volume are configured to provide support to other regions, such as a neck, middle back, upper leg, and/or lower leg region. In this manner, cells vary to provide a desired contour for a typical body type of a user, or be tailored for a specific body type.
At least one or more valves may be provided at an air inflation port 228 as shown in
The top 220 and bottom plies, sheets, or substrates 222 may include different compositions. For example, the bottom substrate 222 may be a more dense, heavy material and/or have other properties to bear weight. Additionally, the material may include a more insulative material to bear weight and/or protect against the elements.
Plies may be any suitable air impermeable material, and may include one or more of woven fabric, impregnated resin, rubber membranes, flexible plastic or polymer sheets, and the like. The materials may include one or more of canvas, plastic, nylon, polyester, solution-dyed acrylic/olefin. The material may further include properties of durability, inflatability, and comfort. The plies or substrates may be of the same or a different material.
The panel may further include a plurality of holes 330 as shown in
When the panel is not being suspended by the tension members, the panel may find further use as a pad on the ground or other surface as shown in
An exemplary inflatable hammock can be used as a standalone device. Alternatively, the panel from a hammock can be configured to be used as a sleeping pad. For example, tension members can be detached from the panel. The reinforcement member, or material at the end of the panel can be removed, for example, with a zipper, snaps, or other locking structure. Alternatively, the straps can be removed from the loops. Other means of attachment discussed herein can be used for removal as well.
Instead of being removable, or in addition to being removable, the tension members can be tucked away and secured in a pocket 504 or 506 as shown in
Exemplary tension members may be stored on or within the pad itself, whether the tension members are removable or not. For example, a locking structure may secure a tension member to the panel when not in use. The locking structure could include clasps, rings, fasteners, hooks, ties, hooks, buckles, Velcro, hook and loop fasteners, carabiners, snaps, or other structures.
The panel may further have a housing structure for securing the tension member. The housing structure may be casing element that includes a compartment, or fold within the panel that is structured to house a corresponding tension member. The casing element may be a pocket that includes an opening or compartment that is dimensioned to hold the tension members. The pocket may be removable or non-removable. The pocket can be attached to the hammock, for example, at an end of the hammock. A pocket would include an opening or compartment that was dimensioned to hold the tension members when the tension members are not in use.
The casing element may further include a closure structure that at least partially closes an opening of the casing to seal off the tension members when the tension members are not in use with the panel and thereby house the tension members. For example, the casing element may include ties, zippers, snaps, or other locking structures discussed herein that may be used to close off the casing element to confine the tension members or close off the tension members within the pocket.
The hammock 550 includes a pad 552 that is configured to support a user thereon. Similar to the other embodiments disclosed herein, the pad 552 may be selectively inflatable (e.g., through a valve). Likewise, the pad 552 may be used as a ground pad. Additionally or alternatively, the pad 550 may be suspended from one or more supports for use as a hammock. For instance, each end of the hammock 550 may include one or more tension members 554 configured for connecting the pad 552 to one or more supports (e.g., frames, trees, etc.) to suspend the pad 552 above the ground. In the illustrated embodiment, the one or more tension members 554 comprise three tension members. One of the tension members 554 is connected to an end of the pad 552 adjacent a first side of the pad 552, a second tension member 554 is connected the end of the pad 552 adjacent a second side of the pad 552, and a third tension member 554 is connected to the end of the pad 552 adjacent to a midway point between the first and second sides of the pad 552. The opposing or free ends of the tension members 554 can be connected to a connector 555 (e.g., clip, hook, etc.) that is configured to connect to a support element (e.g., frame, tree, etc.)
In the illustrated embodiment, the tension members 554 are connected directly or indirectly to the ends of the pad 552. For instance, ends of the tension members 554 may be sewn, clipped, zipped, glued, or tied to the ends of the pad 552. As disclosed herein, the connections between the tension members 554 and the ends of the pad 552 may be permanent or selectively connectable/removable.
The hammock 550 may also include a compartment 556 at each end of the pad 552 or at one end of the pad 552. Each compartment 556 may be integrally formed with or connected to an end of the pad 552. For instance, the material that forms the pad 552 may also form the compartment(s) 556. Alternatively, the compartment(s) 556 may be formed separately from the pad 552 and then attached to the end(s) of the pad 552. Still further, the compartment(s) 556 may be formed by attaching material to the end(s) of the pad 552 to form the compartment(s) 556. In some embodiments, the compartment(s) 556 are selectively connected to and disconnectable from the pad 552.
In the illustrated embodiment, a piece of material is attached to the end of the pad 552. The piece of material is folded so as to form opposing surfaces of the compartment 556. The opposing surfaces of the compartment 556 define an opening 558 into an interior space within the compartment 556. As illustrated in
As illustrated in
As illustrated, the compartment 556 extends across the entire width of the end of the pad 552. In other embodiments, the compartment 556 may extend across only a portion of the width of the end of the pad 552. Furthermore, as shown, the compartment 556 may have a width (extending in the same direction as the width of the pad 552) that is substantially larger than a length thereof. For instance, the width of the compartment 556 may be multiple times (e.g., two, four, five, or ten) longer than the length thereof.
A spreader bar 634 may be included at or near the ends of the panel 602 to maintain the panel in an outspread position, as shown in
The panel may include a channel, for example, a channel formed by bond lines between the top and bottom substrates, through which a spreader bar 634 may be slidably engaged. Alternatively, ends of the panel may be folded over to form a channel. Other attachments besides spreader bars are also anticipated.
Instead of one panel, multiple panels may be used to form the hammock. The multiple panels may be detachable to make the hammock conform to a desired a shape, contour, or other design.
Instead of a plurality of tension members at each end, only one tension member may be used at one or both ends. The panel may have loops in which one or more tension members is threaded. The hammock may further have tensioning members and structures around the entire panel or at least a portion of the panel. Tension members may be interlocking around the panel to form a hanging cocoon-like structure. Hangers may be used to suspend the panel at various points as well. A variety of tensioning structures and principles may be used to incorporate the inflatable elements discussed herein.
As shown in
It is anticipated that the support structure 962 for a hanging chair configuration may be a vertical bar that curves outward and slightly horizontally, as shown. The support structure may further include a support base, such as horizontally extending bars that connect to the vertical bar. Other types of support structures may be used, however, that allow a chair to be suspended in air above ground level and that are configured to provide sufficient clearance to allow the chair to hover over the ground surface below and freely swing in the air.
If is further anticipated that the panel shape of the chair be the same as the panels previously described. Panel shapes for the chair may further include shapes that are narrower on one end and wider and/or flared outward on an opposing end to provide comfort and suitable support of a chair.
While straps and bars have been described in support of the figure shown in
