Description
- This invention relates generally to computer furniture. More specifically, the invention relates to a portable work surface to support a portable computer while working from home or traveling. This invention provides a surface for a user to conveniently work anywhere, even using a portable computer. The novel features of this invention include its sturdiness, its specific design which increases a user's comfort during operation of a laptop, and its improved design to fold easily to fit within a briefcase.
- The need for a convenient portable stand for laptop owners has long been apparent. As the prevalence of computers has increased, so too has the number of laptop computers being utilized. Computers are generally of the desktop variety, allowing a user to comfortably use the computer while seated at a desk. The portable computer, or laptop, demands a similar comfort for users in an increasing variety of locations. Typically, a computer stand for a laptop provides only a surface for the computer to rest. It has replaced the use of one's lap as the primary surface on which one would rest such a computer. This concept generally has several advantages, such as, keeping the user from possibly burning his legs from the heat generated by the internal components of the computer, and allowing the user more comfortable seating during use.
- The concept of portable tables and collapsible tables is not a new one. Such tables attempt to provide maximum comfort for users who need a work surface for any reason in a wide variety of locations. These tables are typically used in a location which contains another convenient flat top on which to work. Currently, portable tables are used for many different uses, including eating, working, reading, and writing. With the increasing amount of portable computers, notebook computers, laptops and personal digital assistants (PDA's), such tables are used to support computers, PDA's, books and utensils for work purposes, as well as plates, forks, utensils and food for eating purposes.
- The increasing number of persons who own laptop computers often prefer to use them while in a seated position, whether sitting in a chair at home, seated vertically in bed, or while seated in transit on a train, plane, or other such transit vehicle. To use a laptop computer in such a fashion typically requires a user to place the computer on his/her lap. This method of use causes the user to sweat, and causes the user muscle fatigue, back aches and neck aches due to the hunched position one must be in to use a laptop in such a fashion. Therefore, laptop users generally prefer some other method of use, such as placing the computer on a portable table, stand or other support means.
- Also increasing is the number of (PDA) users. PDAs such as the PalmPilot® allow users to do work, write, send and receive email, schedule appointments and accomplish other useful tasks from the palm of their hand. PDA users, like laptop users, prefer to use the PDA while seated, either at home or in transit. Using such a PDA without a portable work surface requires a user to support the PDA in one hand while operating it with the other. Prolonged use of a PDA in this fashion can result in aching muscles and cramped hands. Therefore, PDA users prefer an alternative, such as placing the PDA and any accompanying paperwork on a portable table, stand or other support means.
- U.S. Pat. Nos. 1,719,614, 2,449,492, 2,476,620, 3,805,710, 4,119,289, 4,726,556, 5,417,168, and 5,722,624 all disclose collapsable, portable and/or adjustable stands or tables or other support means for supporting items in convenient locations. However, each has various problems and disadvantages. For example, some are uncomfortable or bulky to use, difficult to assemble, require an existing table or desk.
- For example, U.S. Pat. No. 5,722,624, depicted in FIG. 1, describes an adjustable surface that clamps onto an existing tabletop. The prior art surface offers a support means for working, which may support a laptop computer. However, use of this type of support depends on an existing tabletop. That is,
hooks 2 andarms 4 attach to the underside of an existing desk or table. This requirement limits the use of this type of portable surface. This prior art unit also suffers from two disadvantages. First, the user is required to hunch over to see the laptop screen, and second, that the position of a user's hands is not improved. - U.S. Pat. Nos. 2,476,620, 3,805,710, 4,726,556, and 5,417,168 each disclose portable tables which are folding, collapsible, and self-supporting. One problem with the disclosed prior art is that the unit does not fold efficiently, due to the interference of one leg by the other. The bulky legs render the unit difficult to fold, and therefore, difficult to store. The need exists to provide a portable table which folds easily and efficiently, and therefore fits easily into small spaces.
- Another disadvantage with prior art portable surfaces is their instability. Such prior art tables include collapsible truss systems and collapsible triangular-shaped legs which are unstable and poorly balanced. U.S. Pat. Nos. 3,164,353 and 4,726,556 provide examples of tables with such unstable leg systems. These portable tables lack balance and stability as they threaten to collapse and dump their contents which can be costly for laptop users. Therefore, the need exists to provide a portable surface which will remain stable and balanced.
- Further, adjustable tables are subject to a shifting center of gravity, whereby the unit becomes less stable when the unit is adjusted to different heights. For example, U.S. Pat. Nos. 2,449,492, 2,476,620, 3,805,710, 4,119,289, 4,726,556 and 5,417,168 disclose mechanisms for adjusting height adjustable tables. These mechanisms for adjusting the height of a table are often difficult or awkward to use, or involve moving parts which can be dangerous. In particular, U.S. Pat. No. 5,417,168 discloses a height adjustment means which uses two slidably engaged pipes with two sets of apertures, where each set of apertures represents a different height and can be selected through the use of an interlocking “catch member.” The disclosed height adjustment mechanism suffers from ultra-complexity as well as difficulty. To adjust the height of the disclosed invention, it requires one to align two metal tubes on each of two legs and provide that the “catch member” penetrates both holes. Therefore, the need exists for a portable work surface which can be used easily by people of varying heights.
- U.S. Pat. No. 5,511,758 discloses a portable collapsible desk stand, depicted in FIG. 2, designed for notebook computers to help dissipate the heat from a notebook computer. The stand disclosed includes a tilt for more comfortable use, acknowledging the need for a more comfortable portable laptop stand design. However, it discloses a stand which is overly complex to use (i.e., to open and close). That is, sides11 and 11′ are connected to one another with
collapsible arm 13, which is secured withpins 14 and 16. This type of stand is unduly complicated and unstable for use during travel, is fixed at a low height (not idea for maximum comfort), and is unstable and difficult to balance. For example, disclosed is a large folding ‘H’ created by sides 11 and 11′ and collapsible arm formed by 13 and 13′, the torque caused by movement on the surface of the table necessarily renders the unit unstable. Further, placing any object or objects other than a uniformly weighted object (such as a laptop computer) on top of the unit may often cause it to tip. Finally, such a unit is not designed for use during travel. The stand depicted in FIG. 2 is only useful when a user needs to work on an existing flat surface. Since the unit disclosed only has legs 11 and 11′, the unit does not fit comfortably on a user's lap. Therefore, to maximize stability and efficiency, the unit needs to be supported by an already flat surface such as a table or desk. A further disadvantage is that if either ofpins 14 or 16 is accidentally lost, the unit would be rendered unusable. Also, the unit does not elevate the laptop to a comfortable level, causing discomfort to a user's hands while working, and strain on a user's neck caused by constantly looking down at the screen. Therefore, the need exists for a portable, stable unit which can support a laptop, and which can be comfortably used during travel and on any surface, and which can provide a laptop user with comfort to the back, neck and hands. - Next, U.S. Pat. No. 6,115,249 discloses a typical prior art laptop computer stand, as depicted in FIG. 3, having an enhanced cooling feature, and which is horizontally planar, and compact in nature. This general prior art design suffers from several disadvantages. Shown are base21 and stand
member 23, with upwardly extendingfeet members Base 21 and standmember 23 do not increase the height of the unit so as to allow the user to alleviate stresses within the neck, back and shoulders. The unit does contain upwardly extendingfeet members feet members feet members - U.S. Pat. No. 5,896,817 discloses an entire computer desk having a tilted work surface with an adjustable feature which allows a user to select the degree of tilt (e.g., between 30 and 60 degrees). The disadvantage of this design is that it is an entire desk design, which renders it stationary, and thus not applicable to a portable unit.
- A need for a comfortable alternative to the prior art is widely recognized in the art. Several prior art references attempt to solve this problem For example, in an attempt to facilitate a laptop-user's comfort, U.S. Pat. Nos. 5,470,041, 4,648,574 and 3,936,026 disclose a rotatable laptop computer stand support having a swivel base. U.S. Pat. No. 5,553,824 provides a further attempt at providing comfort by disclosing a laptop computer tray with adjustable length. Finally, U.S. Pat. No. 5,137,236 discloses a swivel tripod support apparatus. None of these prior art patents remedied the problem associated with a laptop user's discomfort.
- A review of the known prior art shows a need for a laptop stand designed specifically to relieve the stresses and discomfort which accompany laptop usage. The known prior art makes no reference to providing a portable laptop stand for its common seated use, which reduces the muscle strain in a user's head, shoulders, neck and back. Therefore, there exists a need to develop an improved portable laptop stand which relieves the discomfort in the back, neck, shoulders and wrists of a laptop user, which is light-weight and compact for convenient transportation, and which maintains the flexibility to be used in a number of different ways (e.g., on a table, on a lap while sitting, etc.).
- An object of the present invention is to provide an easy to use portable laptop computer stand which alleviates the muscle strains normally associated with laptop usage. More particularly, the invention provides a portable computer stand specifically designed to reduce muscle strain in a user's neck. The present invention also discloses a particular height which allows the typical laptop user to direct his/her eyes more horizontally as well. This unique design also helps keep a user's head level, thereby further relieving neck strain usually associated with laptop use. That is, the stand includes a raised and tilted work surface (preferably38 degrees) so a user is not forced to crane his/her neck, thereby alleviating the muscle stress associated with laptop usage. The raised and tilted work surface allows a user's eyes to focus more horizontally, keeping the user's head level. By keeping a user's head up, the stress on the user's neck is reduced considerably.
- Another object of the invention is to alleviate the back muscle strain usually associated with laptop usage. The tilt of the work surface and the raised height of the laptop screen when extended, approaches eye level. Therefore, to comfortably view the laptop screen, the user's back can remain upright, relieving the stress associated with laptop usage. The height of the surface disclosed within the current invention allows a user to type comfortably without lowering his/her arms to reach the keyboard. By keeping the user's hands and elbows up, the user's back remains straightened throughout use. Therefore, the stand is ergonomically designed to alleviate the back stress normally accompanying prolonged laptop use.
- Another object of the invention is to relieve the shoulder muscle stresses associated with laptop use. As described above, the raised and tilted work surface keeps a user's head level and back straightened. This positioning aligns the user's head and spine, therefore forcing the shoulders to be positioned over the torso. By keeping the shoulders in line, the current invention reduces or eliminates muscle strain usually accompanying prolonged laptop use.
- Another object of the current invention is to relieve wrist strain associated with laptop usage. The raised and tilted work surface discussed above allows a user to type more comfortably. The laptop, when placed on the raised and tilted work surface presents a keyboard which is ergonomically pleasant to a user's wrists. It is commonly known that a raised and tilted typing surface is less likely to cause carpal-tunnel syndrome in frequent typists, as the wrist is allowed to arch properly during typing. The current invention's raised and tilted work surface allows the laptop (and therefore the laptop keyboard) which is placed thereon to be raised and tilted, thereby relieving some of the stress placed on a laptop user's wrists. The height of the current invention allows a user's wrists to arch correctly, raising the wrists, elbows and shoulders to a comfortable level. By keeping a user's wrists up, the current invention aligns the user's hand, wrist and arm. This alignment provides a user with maximum comfort and could help prevent the onset of carpel-tunnel syndrome, and could relieve the wrist muscle stresses normally associated with laptop usage.
- Yet another object of the invention is to provide a sturdy, safe and comfortable working area for use with a laptop computer. One embodiment contains a shelf between the legs of the stand, below the surface. This shelf increases the sturdiness of the invention by providing extra lateral support. The extra support allows the user to enjoy working with a laptop on the invention without worrying about the unit collapsing, dumping its contents, or injuring the user.
- Still another object of the invention is to provide a portable work surface for use with a laptop computer. One embodiment has hinges which allow the invention to collapse into a substantially flat unit, suitable for carrying in a briefcase, carry-on luggage bag, or the like. Prior art desk stands are bulky and awkward for traveling, while the present invention is small and easily folded to fit in a briefcase or other travel bag. This allows for the convenient use of one's laptop computer while away from home or office.
- Another object of the current invention is to provide a comfortable office away from the office. Alternative embodiments of the current invention have storage space for pencils, pens, paper, and work. Further, the shelf beneath the computer surface allows the user to keep any necessary materials (i.e. disks, papers, notebooks, etc.) within reach to use when needed.
