Title: Suspendable ergonomic space saving height adjustable activity support surface

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to portable furniture, and specifically to a suspendable, ergonomic, space saving, height adjustable work surface. 
     CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority from the following U.S. Provisional Application, the entire disclosure of which is incorporated herein by reference: U.S. Provisional Application No. 63/075,294 (filed Sep. 7, 2020). 
     BACKGROUND OF THE INVENTION 
     In the common home, apartment or office there is often a need for an ergonomic, designated work space that is free of clutter and easily accessible. Many everyday tasks require the use of a clean and comfortable surface. One example is a work or study project that requires a laptop computer, books and notepads, using a desk that is free of unrelated items and can be set up in a quiet area or a more convenient location. Another example is the preparation of a meal using a cutting board that is clean and can be easily moved to an area of less congestion or to establish a more comfortable work position. 
     Because workplaces and needs are always changing, home and work environments ideally would be able to be easily adapted to accommodate a person&#39;s unique work habits. Therefore, a work surface that is clutter free and that can be easily set up and taken down as needed would be highly desirable. 
     There is a global trend toward a greater number of individuals working from home, and therefore a greater number of home offices that need to efficiently fit into existing living environments. A portable work surface that is simple to set up and take down can facilitate working in small spaces, and enable the completion of not only quick tasks but also longer, ergonomically supported work sessions, with minimal interference with the daily habits of a household and minimal impact to its space restrictions. 
     A problem with current portable desks is that their placement is limited to where their feet fit on the floor. They limit walking paths, create tripping hazards, and have mass, weight and support structures that require planning and claim valuable floor space real estate. Traditional work desks have a large footprint and cannot easily be stowed at the end of the day. 
     Current mobile office furniture is particularly frustrating for elderly persons that cannot move cumbersome heavy objects, and for parents with children in the home who need floor space for playing with toys. Available desks rely on legs for support and casters for mobility, and are therefore less than ideal, considering the increase in home office work and its impact on household activities. 
     Adjustable height work surfaces provide for multiple height settings and facilitate postures that improve blood flow throughout the body and accordingly are healthier for a person than those that necessitate a traditional desk sitting posture. 
     Accordingly, there is a need for an ergonomic, space saving work surface with height and angle adjustment and portability features. Such a device would facilitate a variety of work activities in different spaces, increasing efficiency and saving time. 
     SUMMARY OF THE INVENTION

The progression of method operations described are merely examples, however, and the sequence type of operations is not limited to that set forth herein and may be changed as is known in the art, with the exception of operations necessarily occurring in a certain order. Also, descriptions of well-known functions and construction methods may be simplified and/or omitted for increased clarity and conciseness. 
     Numerous variations, modifications, and additional embodiments are possible, and accordingly, all such variations, modifications, and embodiments are to be regarded as being within the spirit and scope of the present invention. For example, regardless of the content of any portion of this application, unless clearly specified to the contrary, there is no requirement for the inclusion in any claim herein or of any application claiming priority hereto of any particular described or illustrated activity or element, any particular sequence of such activities, or any particular interrelationship of such elements. Moreover, any activity may be repeated, any activity may be performed by multiple entities, and/or any element may be duplicated. In addition, the sizes, shapes and configurations of the various structures and elements may vary in order to perform specific functions as necessary for a particular implementation. 
     The present invention provides an activity support device with a body with a support surface that can be suspended from a support surface and the angle of the support surface relative to the support structure can be adjusted. 
     The activity support device is discussed primarily as the support surface being a desk and the support structure being a door. However, it should be understood that the present invention encompasses a body of the device being any suitable or desired shape or configuration, including but not limited to those discussed herein. Further, it should be understood that the present invention encompasses a support surface being of any suitable or desired shape or configuration, including but not limited to those discussed herein. Still further, it should be understood that the present invention encompasses a support structure being any suitable structure, including but not limited to those discussed herein. 
     More particularly, and referring now to  FIGS. 1-7  for illustration purposes as to certain example embodiments, the present invention in preferred embodiments provides an activity support device  100 , including a body  110  having at least one activity support surface  120  (e.g., desk surface  120 ), and at least one suspender  130 A,B integrated with the body  110  and adapted to suspend the body  110  from a support structure  200  (e.g., door  200 ). In preferred embodiments, integration of each suspender  130 A,B with the body  110  enables adjustment of an angle of the support surface  120  relative to the support structure  200 . 
     With regard to the body and the activity support surface of certain embodiments of the present invention, the body and/or the activity support surface can be made of any one or more suitable materials and be formed in any suitable shape. Preferably, the body and/or the activity support surface is made of wood that has been machined or laser cut to a desired shape. In other embodiments, the body and/or the activity support surface can be formed, additionally or alternatively, from other materials that are suited to specific uses. Non-limiting examples include metals such as, for example, stainless steel, preferably with an antimicrobial treatment or coating, that can be applied to or otherwise integrated into bodies and/or activity support surfaces that support food related or medical supply use or storage. Other non-limiting examples include plastics, which can be cleaned easily with spray cleaners and cloths and therefore are suitable for use as creative art project stations or as diaper changing tables. The body and/or the activity support surface can be transparent, partially transparent, or opaque. 
     The materials used for the body and/or the activity support surface can in some embodiments provide alternate or additional functionality. For example, the body and/or the activity support surface can be manufactured, formed and configured to function additionally or alternatively as a dry erase board, chalkboard, magnetic organizer board, cork board, or other functional surface. Unlike traditional desks that use only one primary surface for work, certain embodiments of the invention can utilize a top surface of the body as an activity support surface and an underside of the body as a second functional surface of the types listed above, or other types, due to the “flip-up” space saving feature of certain embodiments of the invention (e.g., positioning of the activity support surface parallel to the support structure, as desired for example herein). 
     The shape of the body and/or activity support surface is preferably rectangular (see, e.g.,  FIG. 1 ), but is not limited to a rectangular shape and can be shaped in a wide variety of circles, ovals, triangles, other geometric shapes, or any custom shape that suits desired uses or tasks. 
     The topography of the body and/or activity support surface preferably can include pockets, cut-outs, or other holes, recesses, or other features that allow for supplies or other items to be stored, when in use or not in use, in specific locations on the work surface and preferably be securely held in such locations when the work surface is being deployed, stowed and otherwise moved. 
     The body and/or activity support surface is preferably flat (see, e.g.,  FIG. 1 ), but bodies and/or activity support surfaces that are not flat are also contemplated. Preferably, the body and/or activity support surface can be featured to have, or be fitted with, anti-slip bars or similar devices or features that help or are otherwise useful to secure work objects (such as, for example, laptop computers) when the body and/or activity support surface is adjusted to desired ergonomic angles. In some embodiments, holes, extensions or other attachment features can be integrated with the body and/or activity support surface to allow for straps, hooks, pouches and other attachment devices to help or otherwise be useful to prevent work objects (such as, for example, laptop computers) from falling during movement of the body and/or activity support surface or use of the body and/or activity support surface at various angles. Storage pouches or other features or devices on or integrated with the body and/or activity support surface can be included also to hold accessories (such as, for example, phone and laptop chargers) or manage cables, cords and other loose or flexible work related items. 
     In some embodiments, additional materials or devices such as rubber pads, grips, adhesive stickers, and other attachment devices can be added to or integrated into the body and/or activity support surface or other parts of the device to create an ideal work space for certain tasks, enabling the securing of work objects related to specific uses, such as, for example, medical tests and devices, toys and craft items, and cables and supplies that are commonly found on desks in offices and need to be organized. In some embodiments, the body and/or activity support surface or other parts of the device can include damage prevention features (such as, for example, padding) to help prevent the development of marks on or damage to surrounding surfaces or objects (such as, for example, doors, walls, and windows) when the work surface is deployed, stowed or used. 
     Referring again to  FIGS. 1-7  for illustration purposes as to certain example embodiments, in preferred embodiments, each suspender  130 A,B includes at least one and preferably a plurality of support loops  130 A,B, each having a length, each loop  130 A,B being releasably secured to the body  110  along the length. 
     With regard to the suspenders of certain embodiments of the present invention, the body and/or activity support surface is preferably hung, suspended or otherwise supported or secured by one or more straps (see, e.g.,  FIG. 1 ). This preferably enables it to “float” at its location so as to minimize its impact to the space below it. However, any suitable manner of suspension, support or securing is contemplated by the invention, including the use of devices or features other than straps. In embodiments that use straps, the straps can be formed of any one or more suitable materials, such as, for example, fabric, plastic, nylon, rope, rubber or metal. The material is preferably suited for the work environment or type. For example, the straps, or all or other parts of the entire device, can be made from plastic, rubber or other waterproof material and accordingly be easily cleaned. In some embodiments, the entire device can be formed of materials that can be washed in a dishwashing machine. 
     In embodiments in which at least one strap is used, one or more straps (e.g., any number of straps) can be used. Preferably, the number of straps used for a configuration is the minimum number required to achieve the support requirements for the intended use of the work surface. Preferably, in certain embodiments, when the work surface is hung from the top of a door, wall, or window, two straps are used (see, e.g.,  FIG. 1 ). Preferably, in certain embodiments, when the body and/or activity support surface is supported by a horizontal strap configuration, a single strap that can tighten is sufficient to hold the body and/or activity support surface above the floor. 
     In preferred embodiments, the strap or other suspension, support or securing feature can be rolled up or otherwise made compact, whether manually or automatically, which increases the ease of transporting the device from one location to another. In some embodiments, the device includes a handle or other carrying feature that, for example, enables the device to be more easily carried as one would carry, for example, a suitcase, briefcase, messenger bag, or the like. 
     In preferred embodiments, the strap is constructed or otherwise configured with a surface that allows for Post-It notes, magnets, lights or other accessories to be attached to the strap, because the strap can, in some of such embodiments, serve as a vertical extension of the body and/or activity support surface. In certain embodiments, the strap can be configured in a substantially vertical orientation to hang the body and/or activity support surface in a substantially horizontal orientation. However, the body and/or activity support surface preferably can be suspended, supported or secured in other orientations as well. In certain embodiments, the strap can be oriented, and function, horizontally. For example, in some of such embodiments, the strap can be horizontally secured to a door in a horizontal loop. Such embodiments and others can be suitable for scenarios in which access to a top of a door is not available or additional attachment solutions are required or desired. 
     Preferably, the straps reduce or eliminate the need for table legs, feet, and casters, and accordingly enable the device to better protect, or prevent damage to, floors and chair legs. 
     Preferably, the strap is not only a feature that provides a primary mechanism for easy attachment to various types of doors, walls, windows, and other building or vehicle features, but also is a feature that provides a primary mechanism for adjustment of the angle and height of the work surface to accommodate various heights and orientations suitable for persons of any size and different work requirements (see, e.g.,  FIGS. 4-7 ). 
     Referring again to  FIGS. 1-7  for illustration purposes as to certain example embodiments, preferably, the body  110  can be released and resecured to each loop  130 A,B to enable adjustment of a position of the body  110  relative to the loop  130 A,B, and adjusting the position changes the angle of the support surface  120  relative to the support structure  200 . Further preferably, the angle can be adjusted such that the support surface  120  is substantially perpendicular to the support structure  200  (e.g., as illustrated in  FIG. 1 ) to place the support surface  120  at an operational angle. Further preferably, the angle can be adjusted such that the support surface  120  is substantially parallel to the support structure  200  (e.g., as illustrated in  FIG. 2 ) to place the support surface  120  at a storage angle. 
     With regard to the integration of the body  110  with each suspender  130 A,B and each suspender  130 A,B being adapted to suspend the body  110 , preferably, the body  110  has at least two through holes  140 A,B, 142 A,B and each loop  130 A,B passes through a respective pair of the holes  140 A, 142 A; 140 B, 142 B to suspend the body  110  by the loops  130 A,B. Further preferably, the body  110  has an underside  122  opposite the support surface  120 , and each loop  130 A,B passes through a respective first through hole  140 A,B from the support surface  120  to the underside  122  and through a respective second through hole  142 A,B from the underside  122  to the support surface  120 . Still further preferably, the body  110  can be released and resecured to each loop  130 A,B at the underside  122  (e.g., by corresponding hook-and-loop features (e.g., Velcro)  180 A,B;  182 A,B on the underside  122  and the loop  130 A,B. 
     In preferred embodiments, the device includes one or more such or other leveling features. Preferably, the leveling feature enables setting the angle of the body and/or activity support surface to any angle that is desirable for the work. Adjustment of the body and/or activity support surface preferably provides ergonomic advantages, such as, for example, by facilitating multiple postures throughout a long work day, which is beneficial for reducing fatigue and related physical stress. Adjustment of the body and/or activity support surface preferably also provides functional advantages, such as, for example, by enabling the angling of the body and/or activity support surface to present a laptop screen at a better viewing angle. For example, nurses or other personnel in a hospital may angle the body and/or activity support surface to have information on a laptop screen be more easily viewed by others in a room, such as, for example, bedridden patients. 
     In preferred embodiments, the materials, mechanisms, or other features that provide the leveling functionality are configured to enable adjustments (e.g., by the user) while the body and/or activity support surface is secured (e.g., by the user). For example, in certain embodiments, as described above and elsewhere herein, hook-and-loop materials (e.g., Velcro) are positioned on the underside of the body so as to enable adjustments while the body and/or activity support surface is secured with two hands (see, e.g.,  FIGS. 2 and 4-7 ). More particularly, for example, in certain preferred embodiments (see, e.g.,  FIGS. 2  and  4 - 7 ) hook-and-loop (e.g., Velcro) components on an underside of the body can interlock with cooperating hook-and-loop (e.g., Velcro) components on the side of the strap that faces the underside of the body when the strap is positioned through slots in the body, to fix the strap to the underside of the body when the body and/or activity support surface is at a desired position. To release the strap from the underside of the body, the hook-and-loop components can be separated (e.g., by a force strong enough to pull the hooks and loops apart). When the strap is unlocked, it can be moved through the slots to adjust the height and/or orientation of the body and/or activity support surface. Then, when the body and/or activity support surface is at the new height and/or orientation, the strap can again be fixed, or locked, to the underside of the body by pressing the hook-and-loop components together. 
     In some of such embodiments, the risk of objects falling from the body and/or activity support surface is preferably greatly reduced. In certain embodiments, the placement of the components and features of the leveling mechanism takes into consideration all of the user&#39;s movements and coordinates them to prevent or resolve any slipping or other displacements. Preferably in such embodiments, it is intended and anticipated that both of the user&#39;s hands will be used to hold the body and/or activity support surface secure during any angle adjustment operation. 
     Referring again to  FIGS. 1-7  for illustration purposes as to certain example embodiments, preferably, each suspender  130 A,B includes a respective suspension connector  150 A,B secured to each loop  130 A,B along the length, each suspension connector  150 A,B being adapted to connect to the support structure  200 . Further preferably, the support structure  200  is a door  200  and each suspension connector  150 A,B includes a hook  152 A,B that hooks onto a top of the door  200 . 
     That is, in preferred embodiments, the straps or other support features that suspend or otherwise support the body and/or activity support surface can be secured above the intended operational location of the work surface. For example, the straps or other support features can be secured or otherwise mounted at the top of a door, wall, ledge or window. Other locations can additionally or alternatively be used for securing the body and/or activity support surface. 
     Preferably, the straps or other support features are secured by a hook (see, e.g.,  FIGS. 1-3 ). However, any manner of attachment using any suitable device or feature is contemplated. Other non-limiting examples include nails, suction cups, hook-and-loop (e.g., Velcro) configurations and clips. In some embodiments in which a hook is used, the hook can be formed from any material, such as, for example, metal, wood, plastic, or a flexible material. In some embodiments that are suitable for attachment to a vehicle, plastic hooks can be used to secure the body and/or activity support surface to the top of a vehicle door or window to provide an accessible activity support surface for travelers without damaging the door or window. In some embodiments in which suction cups are used, the suction cups can be suitable for adhering to the glass or plastic of a window. Preferably, the fasteners, or other attachment devices or features, can adjust or be adjusted to accommodate a variety of support surfaces or elements, such as, for example, a variety of door frames, window frames and wall features. 
     Referring again to  FIGS. 1-7  for illustration purposes as to certain example embodiments, in preferred embodiments, each suspender  130 A,B is adapted to enable adjustment of a suspension distance of the support surface  120  relative to the support structure  200 . 
     In this regard, and referring now additionally to  FIG. 3 , preferably, each suspender  130 A,B includes a respective suspension connector  150 A,B, a respective support strap  132 A,B, and a respective strap lock  160 A,B, each support strap  132 A,B having a respective strap length including a respective connection portion  134 A,B, a respective attachment portion  136 A,B and a respective locked portion  138 A,B, the connection portion  134 A,B being secured to the suspension connector  150 A,B, each of the attachment portion  136 A,B and the locked portion  138 A,B being secured to the strap lock  160 A,B to form a respective support loop  130 A,B between the attachment portion  136 A,B and the locked portion  138 A,B, each loop  130 A,B being integrated with the body  110  as discussed above. 
     Further preferably, at least one of the attachment portion  136 A,B and the locked portion  138 A,B are releasably secured to the strap lock  160 A,B. In this regard, further preferably, each loop  130 A,B has a loop length and the strap lock  160 A,B can be unlocked and relocked to enable adjustment of the loop length, and adjustment of the loop length adjusts the suspension distance. 
     Preferably, the device includes one or more such or other adjustment features. The adjustment features of the device can include but are not limited to height adjustment features that enable the body and/or activity support surface to be set at a range of heights. In some embodiments (see, e.g.,  FIG. 3 ), each strap preferably passes through a locking mechanism that can be unlocked to allow the strap to pass through it so that the lengths of the tension-bearing portions of the strap can be adjusted, and then locked to secure the strap at the desired position. More particularly, in certain preferred embodiments (see, e.g.,  FIGS. 1-7 ), to create a suspended work station, each strap is looped through both the body and/or activity support surface and an over-the-door hook; the straps cradle and suspend the body and/or activity support surface from above; locking and unlocking the straps enables the user to adjust the lengths of the straps, which adjusts the height of the body and/or activity support surface; hook-and-loop components on the straps and the body can be secured to one another to lock the body and/or activity support surface at the desired height, and at a desired orientation (e.g., flat or at another angle). 
     The locking mechanism can use compression, tension, or any other force to secure and release the strap. In some embodiments, the strap preferably includes markings or other indicators that provide information, such as, for example, information about heights that are ideal, suitable or recommended for certain purposes, such as, for example, heights for children of different ages sitting at the activity support surface, heights for adults standing at the activity support surface, and heights for elevated storage. The markings or other indicators are preferably attached, sewn or otherwise integrated into or visible on the strap. 
     In some embodiments, the adjustability is provided by the material of the strap, such as, for example, when the material from which the strap is formed includes rubber or another flexible material. In certain embodiments, the adjustability is provided without mechanisms, assemblies, or moving parts. 
     In some embodiments, the adjustability is made possible by devices, features or materials attached to, connected to, or otherwise integrated with the material of the strap, such as, for example, hook-and-loop (e.g., Velcro) materials sewn onto parts of the strap (see, e.g.,  FIGS. 2 and 4-7 ). These and other configurations preferably enable the locking of the body and/or activity support surface at desired angles, heights, and other orientations (see, e.g.,  FIGS. 2 and 4-7 ), by way of one or more movements that are easily executed by persons of any age. In some embodiments, the length of the supporting strap or straps can be adjusted by other fastening materials, mechanisms, or devices, such as, for example, magnets, buckles, buttons and snaps. 
     Referring again to  FIGS. 1-7 , and now particularly to  FIGS. 4-7 , for illustration purposes as to certain example embodiments, further preferably, as discussed above, each loop  130 A,B has a loop length and each loop  130 A,B is releasably secured to the body  110  along the loop length. Still further preferably, the body  110  can be released and resecured to the loop  130 ,B to enable adjustment of a position of the body  110  relative to the loop  130 A,B, and adjusting the position changes the angle of the support surface  120  relative to the support structure  200 . Even further preferably, the angle can be adjusted such that the support surface  120  is substantially perpendicular to the support structure  200  (e.g., as illustrated in  FIG. 6 ) at a level operational angle, and the angle can be adjusted such that the support surface  120  is at any other desired operational angle relative to the support structure  200  (e.g., at an angle illustrated in  FIG. 7 ). Still further preferably, as discussed above, the body  110  has at least two through holes  140 A, 142 A; 140 B, 142 B and each loop  130 A,B passes through the holes to suspend part of the body  110  by the loop  130 A,B. 
     In preferred embodiments, the device includes one or more such or other space saving features. Preferably, the device uses space that would otherwise have been wasted. For example, the space in front of a door is generally “dead space”, or otherwise not usable because, for example, furniture cannot be placed there because then its use as a doorway would be blocked. Also, for example, other areas of a room may be “dead space” or otherwise unusable as a practical matter due to being too small or strangely shaped. Further, preferably, the device avoids the need to use furniture that requires ground supports (e.g., legs, feet, casters, etc.) and that consequently sacrifices floor space. 
     The space saving features of the present invention include but are not limited to enabling the body and/or activity support surface to be folded toward and away from (or otherwise moved relative to) the support structure (e.g., door, wall, window, or other vertical surface), such that it can be placed in a stowed position (e.g., substantially flat against or parallel to the support structure) and an operating position (e.g., substantially perpendicular or at another angle relative to the support structure) (see, e.g.,  FIG. 2 ). 
     In certain embodiments, in the stowed position, the body and/or activity support surface is flat against or parallel to a door, wall, or window from which it is suspended, and in the operating position, the body and/or activity support surface extends substantially perpendicular to, or at a useful work angle from, the door, wall, or window from which it is suspended (see, e.g.,  FIGS. 1-2 ). Accordingly, when the body and/or activity support surface is deployed in the operating position, it preferably can be used as an activity support surface, and when the body and/or activity support surface is stowed, it preferably allows for the resulting reclaimed space to be open, to avoid congestion, or to be used for other activities or movements. The stowed position further preferably allows the underside of the body and/or activity support surface to be used for purposes suited to the enhanced visibility of the underside when the body and/or activity support surface is stowed. For example, the underside of the body and/or activity support surface can be used as a bulletin board, magnetic board, cork board, view screen, touch screen, chalk board, or dry erase board. 
     The stowed position further preferably allows for storage of frequently used objects, or other objects, on the underside of the body and/or activity support surface, and such objects preferably can be secured in stored positions by pouches (see, e.g.,  FIGS. 1-2 ), boxes, or other compartments or enclosures, or by attachment features, such as, for example, straps, anti-slip bars, hook-and-loop (e.g., Velcro) configurations, and clips. 
     In preferred embodiments, securing of the body and/or activity support surface in the stowed position is made possible by attachment features (such as, for example, hook-and-loop (e.g., Velcro) configurations, magnets, and snaps) located at specific positions on the device. More particularly, for example, in certain preferred embodiments (see, e.g.,  FIGS. 1-3 ), the straps can be unlocked from their supports at or near the top of the door, wall, or window, then pulled through the supports until the body and/or activity support surface pivots toward the door, wall, or window, enough to rest flat against the door, wall, or window; the straps can then again be locked to the supports, to keep the body and/or activity support surface in this stowed position. 
     In certain embodiments having straps for hanging the body and/or activity support surface, and hook-and-loop (e.g., Velcro) configurations integrated with the straps for securing the body and/or activity support surface in the stowed position, the device is lightweight as well as cost-efficient due to the minimal number of parts and the simplicity of operation, and accordingly features a simple, versatile design that can be easily used by persons of any age. 
     Accessory Facilitation Features 
     Referring again to  FIGS. 1-7 , and now particularly to  FIGS. 1-3 , for illustration purposes as to certain example embodiments, as discussed in certain respects above, in preferred embodiments, the activity support device  100  further includes an accessory facilitation feature  170 . In  FIGS. 1-2 , the accessory facilitation feature  170  is shown as a storage feature  170  (e.g., zippered pouch  170 ) hanging from each loop  130 A,B below the body  110 . However, additional and/or alternate accessory facilitation features can include one or more of another storage feature, a cable management feature, anti-slip features, a magnetic surface, and a coated surface adapted for eraseable writing. 
     In preferred embodiments, the underside of the body and/or activity support surface can be utilized both when the body and/or activity support surface is deployed in its operational orientation (e.g., substantially perpendicular or otherwise desirably angled relative to the support structure) as well as when the body and/or activity support surface is stowed in its closed orientation (e.g., substantially parallel to or otherwise against or adjacent the support structure). Therefore, in some of such embodiments, it is preferred that the device include one or more storage features at the underside of the body and/or activity support surface, such as, for example, storage recesses, pouches (see, e.g.,  FIGS. 1-2 ), or enclosures. The storage features preferably are suitable for containing activity related accessories, or other accessories. Examples of accessories include but are not limited to pencils, crayons and craft items (e.g., for kids;); headphones, electronic peripherals and computer accessories (e.g., for adults); and medical supplies, supplements and reminder notes (e.g., for the elderly). In some embodiments, the storage features include but are not limited to nylon pouches with zippers (see, e.g.,  FIGS. 1-2 ). 
     Preferably, the storage features are configured to efficiently store desired items without interference with the activity support surface (e.g., the top side of the body) but in a manner permitting easy and instant access to the stored items when the activity support surface is in operational use. As an example, papers and files can be organized below the body and/or activity support surface so that they are immediately accessible when the body and/or activity support surface is deployed, and stored with the body and/or activity support surface when it is stowed. 
     Preferably, the underside of the body and/or activity support surface is coated or otherwise manufactured to have a surface on which writings and drawings can be written (and preferably erased), so that, for example, when the body and/or activity support surface is stowed, the underside of the body and/or activity support surface can be used as a message board. Accordingly, writing instruments (such as, for example, markers, pens or chalk) can be used to write messages on the underside of the body and/or activity support surface. In some embodiments, the surface of the underside is additionally or alternatively magnetic, so that, for example, magnetic attachment devices can be used to attach papers, photos, and other message items to the underside of the body and/or activity support surface. 
     Operation and Methods of Use 
     In operation, and referring again to  FIGS. 1-7  for illustration purposes as to certain example embodiments, preferably, each suspension connector  150 A,B is connected to the support structure  200  (e.g., by hooking each hook  152 A,B over a top of the door  200 ), and accordingly each strap  132 A,B hangs from a respective suspension connector  150 A,B at the connection portion  134 A,B of the strap  132 A,B. Then each strap  132 A,B, passing from the attachment portion  136 A,B down through the first through hole  140 A,B then up through the second through hole  142 A,B and then up through the strap lock  160 A,B to be locked in the strap lock  160 A,B at the locking portion  138 A,B, forms a support loop  130 A,B from which the body  110  is suspended. 
     When it is desirable for the support surface to be used for an activity, the support surface  120  can be placed at any desired operational angle by detaching the hook-and-loop features  180 A, 182 A; 180 B, 182 B from one another, moving the body  110  along the length of the support loops  130 A,B to move the position of the body  110  relative to the support loops  130 A,B until the support surface  120  is at a desired angle, and then reattaching the hook-and-loop features  180 A, 182 A; 180 B, 182 B to one another. 
     Engagement in an activity using the support surface  120  is then possible as weight applied to the support surface  120  is supported by the support loops  120 A,B as they are connected to the support structure  200  by the support connectors  150 A,B. 
     When it is desirable for the support surface to be stowed against the support structure  200  to free up the space otherwise occupied by the support surface  120  when at the operational angle, the support surface  120  can be placed into a stowed position by detaching the hook-and-loop features  180 A, 182 A; 180 B, 182 B from one another, moving the body  110  along the length of the support loops  130 A,B to move the position of the body  110  relative to the support loops  130 A,B until the support surface  120  is parallel to the support structure  200 , and then reattaching the hook-and-loop features  180 A, 182 A; 180 B, 182 B to one another. 
     In preferred embodiments, the device is configured for portability. In some embodiments, the device is configured for portability by the body and/or activity support surface being dimensioned similarly to the size of a messenger bag, laptop sleeve, or other carrying bags. In some embodiments, the body and/or activity support surface is dimensioned to fit inside one or more of such carrying bags. In some embodiments in which straps are used to support the body and/or activity support surface, the straps can additionally be used as shoulder straps or other handles to facilitate carrying of the body and/or activity support surface. 
     Preferably, components of the device other than the body can be rolled, folded, or otherwise made compact, and secured in such a configuration so as to provide the device with a flat profile for transport. Further preferably, the device is made lightweight due to the minimal number of components and the materials from which the components are made. 
     Accordingly, preferably, the body, straps, and hooks can fit into a travel tote, case, or other device for carrying. For example, the body can either fit into a sleeve, pocket, or recess, or be folded one or more times to fit into a sleeve, pocket, or recess. Further, for example, the straps can be rolled, folded, or otherwise made compact, and stored in a sleeve, pocket, or recess. Further, for example, the hooks can be straightened or folded or otherwise be made flat or compact, and stored in a sleeve, pocket, or recess. Other components can also be made compact and stored in a sleeve, pocket, or recess. 
     Further in preferred embodiments, the device is configured for portability due to the ease of deploying the body (e.g., from its compact, transport configuration) and the ease of packing the body (e.g., into its compact, transport configuration). Preferably, only a few simple movements are required to hang the body and/or activity support surface from a door frame, or otherwise support the body and/or activity support surface on a desired surface, to provide a standing desk (e.g., if the height of the body and/or activity support surface is set to be suitable for a standing user) or other place for work. 
     Further in preferred embodiments, once the body and/or activity support surface is deployed, or during deployment of the body and/or activity support surface, adjustment devices and features can be used to adjust the height of the work surface. For example, in certain embodiments, integrated hook-and-loop (e.g., Velcro) configurations can be manipulated to adjust the height of the work surface (see, e.g.,  FIGS. 4-7 ). 
     Further in preferred embodiments, the device includes organizational or storage features, such as, for example, cable management features and features for storing activity tools and other accessories. For example, these features can be built into or attached to the body and/or activity support surface itself, integrated into straps, or otherwise be made part of the experience of using the device. 
     Preferably, in embodiments in which the body and/or activity support surface is substantially horizontal when deployed, the body and/or activity support surface can be used, for example, as a desk, food preparation surface, play table, or activity support area, without requiring floor space for support. 
     Preferably, in embodiments in which the height and other aspects of the body and/or activity support surface placement or orientation can be adjusted easily with one or a few simple movements, certain ergonomic benefits are enjoyed. For example, such aspects can be adjusted throughout the day to provide a variety of orientations, in accordance with recommendations made by ergonomic experts. Preferably, any desired angle can be chosen and secured with one or a few simple actions, such as, for example, a twist of the body and/or activity support surface and corresponding reconfiguration of integrated hook-and-loop (e.g., Velcro) features on the hanging straps, to secure the revised orientation of the body and/or activity support surface. The multiple adjustment and customization options for the suspended body and/or activity support surface of preferred embodiments of the invention accordingly provide a space-saving but ergonomically beneficial portable activity support surface. 
     Further preferably, when additional space in a room is needed (or if, for example, a door from which the body and/or activity support surface is suspended needs to be moved), the body and/or activity support surface can be easily “flipped up” and secured against the door or other support surface from which it is suspended (see, e.g.,  FIGS. 1-2 ). In certain embodiments, the cooperating use of straps with integrated hook-and-loop (e.g., Velcro) features enables the unlocking of the body and/or activity support surface from the horizontal operational position and the securing of the body and/or activity support surface in the vertical space saving position. In certain embodiments, in such an orientation, the device is compact against the door (e.g., similar to a picture hanging on a wall) and effectively “disappears” from the room, opening up the room to be used in different ways with the benefit of additional space (see, e.g.,  FIGS. 1-2 ). 
     Further preferably, the body and/or activity support surface can be dual-purpose, in that when the body and/or activity support surface is stowed against its support surface (e.g., a door), the underside of the body and/or activity support surface can be utilized as a message board, or utilized for storage or organization. In certain embodiments in which the body and/or activity support surface is made from plastic, writing instruments (such as, for example, dry erase markers) can be used for writing messages on the underside of the body and/or activity support surface (and, for example, associated erasers can be used for erasing messages from the underside of the body and/or activity support surface), or Post-It notes can be attached to and removed from the underside of the body and/or activity support surface. 
     As some examples, children who are using the activity support surface for play or craft activities can quickly organize any messes, and adults can quickly change the space from a home office back to a bedroom. As another example, in some embodiments in which the body and/or activity support surface is plastic, the device can be used in a kitchen for food preparation, then be wiped clean, then converted to its space saving orientation for the underside to become a message board on which a family can share important notes. 
     As needs increase for home spaces to be converted into work spaces, the device of the invention preferably enables the quick and easy transformation of any room from being suitable for one type of use to being suitable for another type of use, by providing a portable, adjustable, “pop-up” activity support surface that can be suspended above the floor without claiming any floor space, and collapsed against the wall without requiring any more wall space than would a picture. The device of the invention accordingly preferably provides the flexibility to enable a person of any age group to quickly initiate work and quickly put work away, without help, tools or additional hardware, and with minimal impact to existing space, furniture or other activities.
