BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to portable work stations capable of being mounted on a user as a backpack and deployed into a workstation to support a computer or other tools which can be used by the user comfortably, securely, and stably while the user is sitting, standing, or even mobile, for example, walking
2. Description of Related Art
Today's busy lifestyle often require maximizing the use of almost every waking moment to work, study, network, and other active behaviors. It has become necessary to utilize time spent commuting by public transportation on the bus, subway, train, plane, riding a car as a passenger, or other modes of transportation. A great deal of time is spent waiting for public transportation, a shared ride, or in line to purchase tickets, obtain a driver's license or other permits, or waiting to meet people.
To this end, the present invention provides a carrying bag capable of being worn as a portable carrying bag, which is capable of being opened to allow an interior wall or surface of the bag to be used as a work surface. The carrying bag is typically in the style of a backpack and, typically in the closed position, the carrying bag is worn on the back. When the user wishes to use a flat work surface, the carriage of the bag is switched around so that the bag portion rests on the chest of the user and the backpack straps fit over the user's shoulders and back. One side of the bag is fixedly attached to the straps, while the other side (the deployable portion) is not attached to the straps. When the bag is opened, a hinge mechanism inside the bag allows the deployable side, typically a compartment, to open up to a position that allows the interior surface of the compartment to become a table-like work surface, which can hold portable computers, games, books, and other electronic devices.
The invention may be used for recreational activities such as at a park, beach, swimming pool, at home in the backyard, and many other similar activities. The present invention offers a compact flat work surface area for activities such as reading, writing, playing computer games, playing board games, playing card games like solitaire, playing a musical instrument, holding musical scores, and the like.
The invention may also be used by service providers, such as landscapers, lawn maintenance and utility installers, building and real estate professionals, scientists working in the field, or people in any profession needing a work surface that is easily, comfortably, and preferably hands-free transported from one location to another.
A preferred use of the mobile workstation of the invention is for transporting and using notebook computers. Though notebook computers are portable, they are either awkward or otherwise impossible to use while one is standing. Even if a user transports a notebook computer to a location for use, the transporting of the device is typically carried in hand by the user or in a backpack or other bag. Setting up the computer for use becomes cumbersome when the computer has to be pulled out of a bag and positioned for use. Typically the user will transport the computer to a location and set it up for use on his lap acting similar to a table-like surface. Difficulties arise when the user desires to move to another location and the laptop has to be picked up with the user's hands to be transported. Even during use on the user's lap, the computer is exposed to the potential damage as it is not secured to the user. During use the user must be cautious not to disturb the unsupported computer in his lap.
In standing positions, the computer must be held by at least one of the user's hands. This presents difficulties for some users, as computers, even considering the lighter available notebook PCs, are typically too heavy for some users to hold in one hand for useful periods. Moreover, efficient keyboard entry and other cursor control (e.g., touchpad) require the use of both hands.
Another example where such a device is needed is for scientists working in the field. If an arborist was studying a tree and needed to record data, he could set up a work surface at the base of the tree and enter any data into a computer contained in the backpack and supported on the mobile workstation, then pack up his materials in the backpack which is already secured to his body, climb the tree, and resume working on the portable platform in the tree by simply unzipping the compartment to expose the computer in a position ready for use.
There is a long-felt need in the art for a compact portable work station that is capable of being carried on the user's body and opens up quickly and easily into a flat surface work area.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to various exemplary embodiments of the invention. The following detailed description is presented for the purpose of describing certain embodiments in detail and is, thus, not to be considered as limiting the invention to the embodiments described. Rather, the true scope of the invention is defined by the claims.
FIG. 1 shows an embodiment of a computer backpack 100 according to the invention, which is a mobile workstation in use. As shown, the backpack or carrying case comprises a compartment 101 for holding objects during transportation. The compartment 101 can be opened and closed by way of a zipper 102 or other fastening device, such as Velcro or snaps. A preferred object to be carried in the compartment 101 is a computer 103. Preferably, compartment 101 is designed to have a fixed side and a moveable side. As shown in FIG. 1, interior surface 104 of compartment 101 can double as a main surface of the backpack 100. In this embodiment, surface or wall 104 is capable of being secured to a user to deter movement of this portion of the compartment during use of the mobile workstation. In this embodiment, surface 104 (also referred to as a wall or side) is fixedly attached to shoulder straps 105. Shoulder straps 105 are capable of holding wall 104 of compartment 101 in place during use and provide for hands-free transportation of objects in compartment 101 and for hands-free supporting of the objects on the mobile workstation platform. Preferred embodiments include shoulder straps 105 capable of releaseable engagement with the backpack 100. The size and shape of compartment 101 is not critical and it is within the skill of the art to design the carrying compartment for various uses.
FIG. 2 shows an embodiment of the computer backpack 200 according to the invention in a deployed position. As shown, compartment 101 has means for opening and closing the compartment, such as zipper 202. A laptop computer 203 is shown open and ready for use by a user. Back wall 204 of the compartment 201 is shown positioned at roughly a 90 degree angle with respect to the remainder of deployed compartment 201. Shoulder straps 205 in this embodiment are capable of releaseable engagement with the backpack by way of the swivel connectors. The shoulder straps 205 can additionally be configured to cross one another when secured on a user, especially across a user's back during use of the mobile workstation to provide additional support and stability. Computer 203 rests within a recess 206 of compartment 201. Once a user has finished using the computer, the computer can be closed and secured within compartment 201 by way of straps 207, which in this embodiment fasten together with Velcro. Once the computer 203 is tucked away in compartment 201, the compartment can be easily and quickly closed using zipper 202 to join compartment 201 with its remaining side 204. In the closed position, the backpack can transport the computer safely and hands free.
As shown in FIG. 2, the backpack 200 is capable of providing a workstation to the user without cumbersome or potential obstructions to the user's hands. For example, the computer 203 can be used within the backpack 200 while strapped on the user without support straps attached to compartment 201 directly. Any straps or other external supporting devices connected to the sides, back, or top surfaces of the compartment 201 will limit the user's range of motion for his hands. What is achieved by the present invention is the ability of the user to move his hands onto and off of the mobile platform without encountering obstructions such as support straps. The mobile workstations according to the invention are mobile, compact, quickly and easily convertible to active and inactive status to enable a user to work on the mobile platform in one location, temporarily store the tools on the workstation in a backpack for transportation, then resume working in another location on the platform in very few steps.

FIG. 6A shows an embodiment of a frame 610 for supporting and deploying the backpack into a mobile workstation that can be used to deploy the backpack and expose the mobile workstation platform in a position, for example, roughly a 90 degree angle relative to the front of the user, to support a tool (such as a computer) for comfortable, secure, and stable use by a user. In this embodiment, frame 610 comprises a first elongated strip 611. Strip or support 611 is preferably installed under material covering the back wall of the major compartment of the backpack. Support 611 is preferably comprised of aluminum or other lightweight metal or equivalent material capable of providing comparable rigidity and support. Member 611 is operably connected by way of a pivot connection 612 (or hinge) to a second elongated support member 615. Support member 615 is preferably installed under material covering the opposing wall of the major carrying compartment of the backpack so that when the backpack is closed elongated members 611 and 615 are parallel. In this embodiment, support member 615 has a bend 614 and additional length 613 configured to provide spacing between members 611 and 615 when device 610 is closed. This configuration provides for protection for objects carried within the major carrying compartment of the backpack to for example prevent crushing of the objects by outside forces imposed on the exterior walls of the backpack. One or more support frames 610 can be incorporated into the backpack, with more than one frame embodiments providing additional support.
FIG. 6B shows the frame 611 for supporting and deploying the backpack into a mobile workstation as shown in 6A, which is in an open position, fully deployed to provide a 90 degree angle between the elongated members of the frame. As shown, when device 611 is open, support 611 and support 615 are positioned with respect to one another at a right angle. In this embodiment, this angular spacing is achieved or facilitated by the combination of the hinge 612, section 613, and bend 614 with elongate members 611 and 615.
FIG. 6C shows a side-by-side comparison of two embodiments of representative frames 610 for supporting and deploying the backpack into a mobile workstation according to the invention. As shown, strip 611 a can be a thin strip of aluminum or other similarly rigid material, with gussets 611 b welded, soldered, or otherwise fixedly attached to strip 611 a. Gussets 611 b provide additional strength to frame 610 especially for thin metal strips 611 a. Such embodiments can be lighter and easier or less costly to manufacture than thicker aluminum counterparts, such as the other extruded aluminum member 611 shown. An alternative embodiment for hinge 611 c is also provided, where member 611 c can be soldered or welded, or otherwise fixedly attached to member 611 a. Member 611 a is the portion of the frame 610 that would be installed in the wall of the backpack that resides on a user during use. Elongate support member 611 a can be combined with elongate member 615 to provide a complete support device or frame 610.
