Provisional Application Serial No. 60/173,086 filed 12/27/1999 entitled MOUSE PAD HOLDER, and claims any and all benefits to which it is entitled therefrom.

FIELD OF THE INVENTION This invention relates to the positioning of the mouse pad on the arm of an armchair so as to prevent the strenuous stretching of the arm when manipulating a mouse.

BACKGROUND OF THE INVENTION The two most common devices for entering information into a computer are the keyboard and the mouse. Most computer keyboards resemble typewriter keyboards in the arrangement of their letter keys, but have additional keys for special computer tasks. Four arrow keys, for example, enable a computer user to move an electronic marker called the insertion point up, down, to the left, or to the right. The insertion point indicates where the next character typed will appear.

Keys can also be reprogrammed. For instance, a user can reprogram a key to insert a letter from a different alphabet. The keyboard also has a numerical keypad to help users enter numbers quickly.

The graphical user interface (GUI), the way of interacting with a computer using pictures and other visual elements displayed on a computer screen and the subsequent use of the device

called a mouse--or a similar device called trackball-which controls a pointer on the computer screen; moving of the pointer to an icon and pressing a button would produce the action represented by that icon. Prior to this current invention, the issue of the comfortable positioning of the mouse has not been specifically addressed.

Manipulating the mouse from a position on the desk or on the keyboard extension requires the arm to be constantly stretched and the back to be bent forward rather than in a reclining position. This positioning of the arm and the back exerts pressure on the arm, the neck, and the back and causes unnecessary pain and fatigue in these parts of the body.

Though the keyboard holder addresses the issue of the positioning of the keyboard itself, this device, at worst, fails to tackle the problem pertaining to the comfortable positioning of the mouse and at best, assumes that the problem of the positioning of both of these devices is the same, which is an invalid assumption, as will be further explained later on. Thus far, computer users have had to place the mouse pad close to the keyboard whether on the desk or on the keyboard holder and to manipulate the mouse from that position.

Without constraint of theory, the amount and frequency of use of the mouse is not necessarily identical or proportionate to that of the keyboard. A computer user may use one of them or the other for any length of time or frequency, independent of the amount and frequency of the use of the other. The positioning of these two tools, therefore, does not necessarily have to be identical and, in fact, has to be different if the comfort of a greatest number of individual computer users is to be optimized. This applicant, whose work with a computer used to be bound by strain and pain in the arm, neck and back, stumbled on a resolution of this issue while trying to make himself comfortable working with his computer. The applicant simply added to the arm of his chair a board on which to put the mouse pad so the mouse could be manipulated from that position. The

muscle strain and pain disappeared.

Furniture consists of chairs, tables, beds, and other pieces that provide comfort and convenience in our daily lives. Many kinds of furniture are used in homes, schools, and offices.

We relax on comfortable couches, and we store various belongings in chests, dressers, and bookcases.

Desks provide a place for study and paperwork. Numerous television sets and phonographs have handsome cabinets, and so they also serve as pieces of furniture. It would be desirable to provide any chair with the capability of becoming an ergonomic or biomechanical workstation.

SUMMARY AND ADVANTAGES It is an object and an advantage of the present invention to provide an enhanced biomechanical workstation. It is a further object and advantage of the present invention to provide a strain-free system for adapting a conventional chair into an enhanced biomechanical workstation.

It is also an object and an advantage of the present invention to provide a means for converting a conventional chair into an ergonomic workstation.

It is a further object and advantage of the present invention to provide such enhanced biomechanical workstation comprising a detachable or permanently mounted work platform..

It is yet a further object and advantage of the present invention to provide such enhanced biomechanical workstation comprising a detachable or permanently mounted clamp portion for coupling between the work platform and the arm of a user's chair.

It would be advantageous to provide a keyboard holder whereby the position of the keyboard relative to the computer user can be adjusted to a proximity and a level comfortable to the computer user.

Thus, the present invention is a biomechanical workstation, thus providing strain-free use of keyboards and mousing devices while seated in ordinary chairs.

As mentioned above, the overall size and shape of the work platform 114 of the biomechanical workstation 100 can be any appropriate and/or operative size and shape. It can be square, rectangular, oval, or other. The work platform 114 could be the size of a mousing surface portion 104 only, it could be the size of just a mousing surface portion 104 and a portion to support a keyboard 106, or it could be the size of an entire desk to allow a plurality of items to be placed thereon.

As shown best in FIGS. 3 and 4, in a preferred embodiment the work platform 114 comprises a recessed or cut-out section 122. This allows a user to bring the work platform 114 closer or farther away, as desired. Along with alternate sizes and shapes of such platform, the work platform 114 can optionally comprised any recessed portion, pockets, recesses, indentations, or covered tray areas, such as for holding paper clips, track ball or mouse devices 108, pencils or pens, rulers, etc.

In a preferred embodiment, the lower surface 124 of the work platform 114 has one or more pair of rails or grooved tracks 126 on one or both ends. (As shown in FIG. 4,2 sets of grooved tracks 126 are shown). Such pairs of grooved tracks 124 are particularly suited to slide over and/or otherwise couple to the coupling portion 112. In a preferred embodiment, other mounting means 128 can be used to couple the platform 114 to the coupling portion 112 at a certain position, or otherwise act as"stops"for a sliding configuration. Based on the foregoing, it will be apparent to those skilled in the art that additional means for coupling the work platform 114

to the coupling portion 112, including clamp means, hook and loop materials, snaps, screws, straps, etc. such attachment means are intended to provide detachable, rigid and secure coupling between the work platform 114 and the coupling portion 112, such as shown in FIG. 2.

In this embodiment, the work platform 112a comprises corresponding and mating circular openings 140 which are used for coupling the work platform 114a to the coupling portion 112a. Additionally, keyboard stop tabs 142 are positioned on the work platform 114a to provide secure and gripping contact with a keyboard (not shown). In this embodiment, the biomechanical workstation 100a can be used with a rotating or rocking chair, without fear of a keyboard falling off of the platform 114a..

FIG. 8 is a representative isometric view of another alternate preferred embodiment of the biomechanical workstation 200 of the present invention. This preferred embodiment comprises an articulating arm 202 coupled to clamping portion 212. The articulating arm 202 is formed with at least 2 elongated arm portions 204 and at least about 3 hinges 206 or other swivel means. The work platform 314 swivels independently of the articulating arm 202, and this results in highly adaptable, maneuverable surface which can be utilized individually and uniquely by all users. A

keyboard and other work surfaces can be placed exactly where most efficient and strain-relieving.

FIG. 9 is a representative isometric view of another alternate preferred embodiment of the biomechanical workstation 300 of the present invention. In this embodiment, the articulating arm 302 couples directly to the chair arm 310. Thus, it will be apparent from the foregoing that the work platform 314 and articulating arm 302 can be permanently mounted onto the arm 310 of a chair.

In a preferred embodiment, the present invention comprises a double platform and clamping system. Utilizing both arms of a chair, the present invention (as shown in FIGS. 1-9) can be adapted for supporting not only a keyboard 106 and other working peripherals, but the work platform could also a thin or flat panel monitor. Properly mounted onto a work platform so that it would not be inadvertently tipped over, the user could alternatingly pivot either a right side or a left side work platform, optionally utilizing articulating arms, so that multiple types of computer equipment, including keyboards, monitors, mouse devices, etc., can be used simultaneously or sequentially, within a given work session or within any one or more of multiple work sessions.
