Keyboard tray
A keyboard tray includes a chamber accessed through opposite side slots through which slides a slidable mouse tray. The slidable mouse tray and a lower keyboard body include groups of one of guide and reinforcing ribs and guide and reinforcing slots. A mouse cord supporting member can be utilized with either of opposite exposed side portions of the slidable mouse tray. The keyboard try is also preferably constructed of two bodies having alignment pins and openings for accurate registration incident to assembly of the keyboard tray.
This invention is directed to a keyboard tray, particularly adapted for supporting any one of a variety of conventional keyboards and a mouse associated therewith.
The keyboard tray is preferably rigidly secured to a keyboard tray supporting arm which is articulately mounted relative to a desk upon which is supported a conventional personal computer (PC). The keyboard tray houses a relatively flat mouse tray in slidable relationship thereto. The keyboard tray is preferably constructed from two pieces of compression-molded, injection-molded, vacuum-molded or like formed polymeric/copolymeric synthetic plastic material which when united along a periphery thereof define a bottom wall or surface, an upper supporting wall or surface, and a peripheral wall therebetween. The peripheral wall includes spaced opposite side wall portions which each include a slot through which the mouse tray can slide between operative and inoperative positions.
A keyboard tray as just described is fully disclosed in U.S. Pat. No. 5,655,743 in the name of Charles A. Gillis which issued on Aug. 12, 1997. The present invention constitutes an improvement over the invention of the latter patent and the prior art patents listed therein which are incorporated hereat by reference, along with U.S. Pat. No. 6,694,895 granted on Feb. 24, 2004, also in the name of Charles A. Gillis.
SUMMARY OF THE INVENTIONThe present invention improves prior art keyboard trays and particularly the keyboard tray of U.S. Pat. No. 5,655,743 by (1) constructing the slidable tray and a chamber in which the slidable tray slides with cooperative substantially parallel guiding ribs and guiding grooves arranged in at least two spaced substantially parallel groups with at least two guiding ribs per group which define a guiding surface curved in a direction transverse to the direction of sliding movement of the slidable tray, (2) providing a removable mouse cord supporting member having a U-shaped slot in which a mouse cord can be secured and (3) constructing the keyboard tray from two members each including a peripheral wall and having a plurality of inter-engaged registration pins and openings for aligning the individual keyboard members incident to permanently securing the same to each other.
With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.
A novel keyboard tray constructed in accordance with this invention is fully illustrated in the drawings and is generally designated by the reference numeral 10 which supports any one of a variety of a conventional keyboards K (
The keyboard tray 10 includes a slidable mouse tray 15 which can be housed substantially entirely within the keyboard 10 (
The keyboard tray 10 is preferably injection-molded, compression-molded or otherwise molded from polymeric/copolymeric synthetic plastic material and has two separate individual keyboard bodies or keyboard members, namely, an upper keyboard body 21 and a lower keyboard body 22.
The upper keyboard body 21 (
A peripheral reinforcing rib 64 projects upwardly from the upper wall surface 30 of the upper keyboard body 21 along the rear peripheral wall 31 and the side peripheral walls 33, 34, and includes upwardly opening slots S into either of which can be located the power cord C of the keyboard K (
At each corner (unnumbered) of the upper keyboard body 21 and midway of the rear and front walls 31, 32, respectively, there is provided a downwardly opening generally cylindrical alignment bore or opening 58 (
The mouse slide tray 15 is of a generally polygonal or rectangular configuration and includes two relatively large shallow substantially rectangular mouse-receiving recesses R3, R4 (
The slidable mouse tray 15 is further reinforced along the peripheral side walls 26, 27 by a plurality of downwardly projecting spaced reinforcing ribs 63 (
The lower keyboard body 22 includes a lower wall 70 (
The side peripheral walls 73, 74 of the lower keyboard body 22 are each shorter in height than the sidewalls 33, 34, respectively, of the upper keyboard body 21 and therewith define respective generally rectangular side openings or slots 76 (
The lower keyboard body 22 is reinforced by four groups 81 through 84 (
When assembled in the manner best illustrated in
A mouse cord member 100 (
The bottom wall 70 (
Although a preferred embodiment of the invention has been specifically illustrated and described herein, it is to be understood that minor variations may be made in the article without departing from the spirit and scope of the invention, as defined by the appended claims.
