Adjusting mechanism for a chair mounted keyboard and mouse platform
The present invention is an assembly adapted for attachment to a chair. It includes a first embodiment adapted to support a computer keyboard (w/mouse platform) and a second embodiment adapted to support a computer mouse only. Both embodiments are releasably secured to the armrests of a chair and are pivotally and longitudinally adjustable. The keyboard-supporting embodiment is connected to both armrests and the mouse only supporting embodiment is connected to a left armrest for a left-handed mouse user and to the right armrest for a right-handed mouse user.
1. Field of the Invention
This invention relates, generally, to furniture having utility in connection with computers. More particularly, it relates to a chair mounted assembly for computer users that has platforms for supporting a computer keyboard and a computer mouse. Specifically, the present invention relates to an adjusting mechanism by which to select the disposition of the platforms relative to the chair from which it is mounted for the maximum convenience of the person seated in the chair.
2. Description of the Prior Art
Most personal computer installations require a user to sit in a conventional chair in front of a keyboard that is positioned on a desk top. A mouse for controlling the cursor is typically supported on the same desktop. As a result, the individual is restricted in movement, being confined to the chair so that he or she can reach the keyboard and the mouse. The chair itself cannot be moved far, either, because if it is placed at a distance away from the keyboard and mouse, those items become inaccessible.
Since the modern workplace requires people to be near a keyboard and a mouse all day long, it would be helpful if computer-related furniture were not so restrictive. A few inventors have addressed this problem. However, the solutions that have heretofore been found include complex mechanisms that are impractical from a cost standpoint. Significantly, the earlier solutions require specially built chairs.
Thus, there remains a need for a practical, inexpensive structure that provides an enhanced degree of freedom to a computer user seated in a chair. More particularly, there is a need for a structure that could be retrofit to an existing conventional chair so that the cost of the final product would not be prohibitive.
SUMMARY OF THE INVENTIONThe present invention is an assembly adapted for attachment to a chair. It includes a first embodiment adapted to support a computer keyboard (w/mouse platform) and a second embodiment adapted to support a computer mouse only. Both embodiments are releasably secured to the armrests of a chair and are pivotally and longitudinally adjustable. The keyboard-supporting embodiment is connected to both armrests and the mouse only supporting embodiment is connected to a left armrest for a left-handed mouse user and to the right armrest for a right-handed mouse user.
The invention enables a person to operate the keyboard and/or a computer mouse while seated in the chair. The person may sit comfortably in the chair in any desired posture or orientation without regard to physical placement of a computer means or a computer monitor means with which the computer keyboard and computer mouse are associated.
Although the novel assembly may be retrofit to any chair having armrests, the preferred chair for use with the inventive assembly is an ergonomically-designed chair having multiple features for enhancing safety and comfort. Such features include a pneumatic height adjustment, coasters that provide mobility throughout an office, a three hundred sixty degree swivel to allow access to an entire work area, a tilt tension adjustment means, contoured seat and back rest parts, and the like.
Both embodiments of subject invention utilize an adjusting mechanism that is used for placement of a mouse platform or a keyboard platform relative to a user seated in a chair. The adjusting mechanism includes a clamping means adapted to be secured to a chairs armrests. A pivoting extension arm extends outward from the clamping means and allows for angular adjustment of the extension arm relative to the armrest. The extension arm can also be longitudinally adjusted to different lengths and is received by collars affixed to either the mouse or keyboard platforms. The adjusting mechanism allows for convenient manipulation of the mouse or keyboard platforms by a computer user seated in a chair.
It is a primary object of this invention to provide a chair in which a computer user can comfortably sit while operating a computer keyboard and a computer mouse without being confined to the immediate vicinity of a desk top.
Another object is to provide the needed structure in a way that incorporates a commercially-available chair so that the product is economical to manufacture and thus affordable by consumers.
These and other important objects, features, and advantages of the invention will become apparent as this description proceeds.
The invention accordingly comprises the features of construction, combination of elements and arrangement of parts that will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.
The invention is best understood from the following detailed description when read in connection with the accompanying drawings, which illustrate an embodiment of the present invention:
