Description
Field of the Invention
The present invention concerns a computer keyboard support having a movable extension that supports a data input device, such as a mouse, for controlling a cursor position on a computer viewing screen.
Background Art
The personal computer revolution has placed personal computers and computer terminals on corporate and home desktops throughout the world. Almost all such computers and terminals allow data entry through an alphanumeric keyboard. Often such a keyboard rests on a level desktop surface which is the same as the surface that supports a computer base unit and a viewing monitor or screen.
Especially when the user must work at the computer for long periods of time, it is important to be able to adjust the position and/or orientation of the keyboard. Built in tabs that form an integral part of the keyboard allow for limited tilt adjustment. To allow more flexibility in positioning a keyboard to suit a user's ergonomic requirements, however, the keyboard needs its own support.
Different types of keyboard supports are sold by Work-Rite Ergonomics Accessories, Inc. the assignee of the present invention. One such keyboard support is moveably supported by a track and support mechanism that allows the keyboard to be moved out from under a user's desk and then stored beneath the desk when the keyboard is not in use. This keyboard support also allows the user to adjust both the angle and the height of the keyboard in relation to the user.
A common personal computer input device that has received wide acceptance is a two dimensional input control commonly referred to as a mouse. As the mouse is moved over a flat surface a roller that extends from a bottom of the mouse rotates and this rotation is translated into electrical signals that are transmitted to an interface of the personal computer. The movement of the mouse on the surface causes a corresponding movement of an arrow on the computer screen. By moving the arrow to point at a desired icon, function block, dialog box, or pull down menu, the user can actuate switches on the mouse to select or pick icons, or functions, actuate pull-down menus, select a block of text for editing, enter data, etc.
U.S. Pat. No. 5,655,743 to Gillis concerns a keyboard tray which is formed from two relatively shallow molded bodies united along a periphery to define a relatively flat, internal chamber through either of opposite side edges of the keyboard tray. A mouse tray can project outwardly of the internal chamber through either of opposite side edges of the keyboard tray.
Summary of the Invention
One exemplary embodiment of the present invention concerns a keyboard support for a personal computer. The keyboard support includes a moveable support adapted to support a moveable pointer input device, such as a mouse. To accommodate the moveable support, the keyboard support includes a support body having a throughpassage that passes through the support body and opens on opposite sides of the support body. The moveable support is slidably positioned in the throughpassage. The support body defines a support surface configured to accommodate an alphanumeric keyboard for inputting signals corresponding to alphanumeric symbols to the computer.
The pointer device typically includes a roller that requires a generally flat surface for its support and rotation of the roller. Although the term "mouse" has become almost universally used for a moveable pointer input device, other terms such as "trackball" can be used interchangeably with the term "mouse".
The moveable support or moveable mouse support fits within a portion of the throughpassage of the keyboard support and can be extended outwardly from the keyboard support to define a mouse support surface. A portion of the mouse support extends in front of a front edge of a keyboard as the keyboard rests on the support surface.
The exemplary keyboard support includes a support body having a curved slot that extends through the support body. The keyboard support also includes a moveable mouse support that defines an arcuate body that fits within the curved slot of the support body and can be pushed back and forth through the curved slot to extend beyond one or the other side of the keyboard support body. Due to its curved or arcuate shape of the mouse support, an exemplary embodiment of the moveable mouse support defines a work region that extends beyond a front edge of the keyboard support body.
These and other objects, advantages, and features of the exemplary embodiment of the invention are described in detail in conjunction with the accompanying drawings.

Detailed Description of an Exemplary Embodiment
Turning now to the drawings, FIG. 1 is a perspective view of a keyboard support 10 used to support a keyboard 12 and a mouse 13 in a position for typing and mouse controlled function selection and/or data entry. The keyboard 12 is typically coupled to a computer or workstation (not shown) resting on a desk (shown in dashed line at 14) for providing a working surface for a user. The keyboard support 10 may be mounted to a base that includes a retractable arm (shown in dashed line at 16) that extends out from beneath the desk 14 and allows the user to adjustably position the keyboard 12 relative to the desk 14.
The keyboard support 10 includes a support body 20 having a throughpassage 22 (FIG. 2) that defines a rack for a moveable mouse support 30. A top surface 32 of the support body 20 defines a support surface configured to accomodate the keyboard 12. The mouse support 30 fits within a portion of the throughpassage 22 of the support body 20 and can be moved to extend outwardly from the support body to define a mouse support surface 38 that extends to a region 40 (FIG. 1) in front of a front edge 42 of the keyboard 12 as the keyboard is resting on the keyboard support 10. A wrist support 44 extends above the supporting surface 32 and is attached to a front region of the support body. The wrist support 44 contacts a user's wrist as the user types at the keyboard 12.
The throughpassage 22 is a curved slot that extends through the support body 20. The mouse support 30 is an arcuate board-like member having the same radius of curvature so that it fits within the curved slot defined by the throughpassage 22. A position of the mouse support 30 relative the support body 20 is adjusted by pushing the mouse support 30 back and forth through the slot-shaped throughpassage 22. The mouse support 30 can be extended by the user to a position beyond one or the other side of the keyboard support 10 so that the curve of the arcuate mouse support body positions a work region defined by the mouse support 30 to either the left and foward of the keyboard 12 or to the right and forward of the keyboard 12. When in an intermediate or middle position, the mouse support 30 is hidden from view within the support body 20.
As seen in the exploded perspective view of FIG. 2, the keyboard support body 20 is made up of top and bottom body pieces 110, 112 that mate with each other along an outer periphery of the support body 20. A top piece 110 is generally rectangular in plan view. A forwardmost edge 113 of the top piece 110 extends between two rounded corners 114, 115 and a bottom edge 1 18 extends between two rounded corners 116, 117. A distance D1 (FIG. 3) from the top edge 113 to the bottom edge 118 of the top piece is about 131/4 inches in one exemplary embodiment of the invention. The top piece 110 defines the top support surface 32 on which the keyboard 12 is disposed.
As seen in the perspective view of FIG. 2, the bottom piece 112 also has two rounded corners 122, 123 and a forwardmost edge made up of three segments 119, 120, 121. The bottom piece defines the arcuate throughpassage or cutout 22 which accomodates back and forth movement of the mouse support 30. The cutout 22 is bound by front and rear raised segments 132, 134. The front raised portion 132 has a curved edge 136 that extends in an arc from a left side of the bottom piece 112 to a right side of the bottom piece 112. The curved edge 136 is generally symmetric about a centerline coincident with the line 5--5 of FIG. 3 passing through the bottom piece 112. The second or rear raised portion 134 defines a second edge 138 facing the curved edge 136. The front and rear raised portions 132, 134, confine the mouse support 30 to arcuate movement along a curved path of travel.
In accordance with an exemplary embodiment of the invention, the body piece 110 and the mouse support 30 are machined composite plastic (paper based phenolic) members. The bottom body piece 112 is a metal (steel) stamping having a thickness of about 0.073 inches. This metal stamping is deburred and painted prior to assembly of the support 10. A bottom surface of the top piece 110 rests against the raised portions 132, 134 of the bottom piece 112. Connectors (not shown) pass through aligned holes H1 in the two pieces 110, 112 to attach the two pieces together after the mouse support 30 has been positioned within the cutout 22.
As seen in the perspective view of FIG. 2, a pin 140 extends upwardly from a generally planar surface 142 of the curved cutout 22. The pin 140 forms a stop that limits the extent of movement of the mouse support. The mouse support 30 defines an arcuate slot 144 that extends up into a body of the mouse support 30 from a bottom surface 146 of that support. When assembled the pin 140 extends into the slot 144 as seen in the section view of FIG. 5. When the user pulls the mouse support 30 out from the keyboard support body 20 he or she is able to move the mouse support until the pin 140 butts against an end of the slot 144. In the configuration shown in FIG. 1, with the mouse support extending beyond the right hand side of the support 20 the pin 140 is butting against a right hand end 150 (FIG. 3) of the slot and with the mouse support 30 extending from the left hand side the pin 144 buts against the left hand end 152.
The bottom piece 112 of the support body 20 has a width W of about 171/2 inches from the right edge 160 to the left edge 162. This is shorter than the width of the top piece 110 and allows the user to reach under the keyboard support and grasp the mouse support 30. In order to allow the user to more easily grasp the mouse support 30, the mouse support 30 defines two notches 164, 166 along two oppositely facing generally straight edge portions 170, 172 (FIG. 2) of the support 30. As seen in the plan view of FIG. 3 the straight edge portions 170, 172 generally align with opposite sides 180, 182 of the support 10 with the mouse support 30 in its hidden middle position. As seen in the perspective view of FIG. 1, beveled or angled edges 184, 186 of the mouse support 30 extend generally parallel to the front edge 42 of the keyboard and also extend in front of the front edge of the wrist support 44.
Edges of the top piece 110 and the mouse support 30 are exposed to contact by the user. As seen in the section view of FIG. 6, the top piece 110 and the mouse support 30 have rounded or contoured edges 110a, 30a respectively that extend around an outer periphery of those members.
While the present invention has been described with a degree of particularlity, it is the intent that the invention include all modifications and alterations from the disclosed design falling with the spirit or scope of the appended claims.
