This disclosure relates to keyboard trays for desktops.
Keyboard trays mounted below desktops free up desktop space and facilitate ergonomic positioning of keyboards for users.
Keyboard trays disclosed herein include a slidable rail with a keyboard platform mount pivot. A keyboard platform attached to the keyboard platform mount is both slidable via the slide and tiltable relative to the slide via the keyboard platform mount pivot.
In one example, an adjustable keyboard tray includes a desk mount configured to secure the adjustable keyboard tray to a desktop, a slide including a fixed rail attached to the desk mount and a slidable rail slidably mated with the fixed rail, a keyboard platform mount attached to the slidable rail with a keyboard platform mount pivot, and a keyboard platform attached to the keyboard platform mount, the keyboard platform being slidable relative to the desk mount via the slide and tiltable relative to the slide via the keyboard platform mount pivot.
In another example, a desktop assembly includes a desktop and an adjustable keyboard tray. The adjustable keyboard tray includes a desk mount securing the adjustable keyboard tray to the desktop, a slide including a fixed rail attached to the desk mount and a slidable rail slidably mated with the fixed rail, a keyboard platform mount attached to the slidable rail with a keyboard platform mount pivot, and a keyboard platform attached to the keyboard platform mount, the keyboard platform being slidable relative to the desk mount and the desktop via the slide and tiltable relative to the slide and the desktop via the keyboard platform mount pivot.
In some examples, keyboard platform 101 may be primarily formed from a wood product. For example, the wood product may include natural wood, plywood, and/or a fiberboard comprising wood particles and a binding agent. Such fiberboards include medium density fiberboard (MDF). Some of such examples may include a laminate over at least a portion of the wood product, such as a laminate forming the upper platform surface.
As compared to other design incorporating primarily plastic materials, the wood product may provide increased rigidity as well as facilitate unique shapes. For example, while plastic components must have tapered side surfaces to allow removal from a mold, surfaces of keyboard platform sections 101A, 101B may form right angles relative to each other and an ergonomically tapered front edge. In another variation, all or portions of the side surfaces of keyboard platform sections 101A, 101B may include a rounded, convex, surface formed by edge banding between the upper surfaces and the undersides. The edge banding covers and seals the side surfaces of the base material, providing protection and improving the appearance of the product.
Adjustable keyboard tray 100 includes two clamps 104A, 104B (collectively, “clamps 104”), which function as desk mounts to secure the adjustable keyboard tray 100 by engaging an edge of a desktop, such as desktop 201 (
Alternative designs for adjustable keyboard tray 100 can include any variety of desk mounts, in addition to or instead of clamps 104. Such varieties of desk mounts include but are not limited to, brackets and screws as described with respect to adjustable keyboard tray 400 (
The fixed rail 114 is one component of a right tilting track 103A, and a left tilting track 103B, (collectively, “tilting tracks 103”) of the adjustable keyboard tray 100. The tilting tracks 103 include the same components, but in a reversed, mirrored orientation relative to each other. Each tilting track 103 includes a slide 120 with a fixed rail 114 attached to one of the clamps 104. Each slide 120 includes a slideable rail 130 with a channel track 113 to receive the fixed rail 114 such that slideable rail 130 is slideably mated with the fixed rail 114. The channel track 113 may be fixed to the bent frame of slideable rail 130 via any suitable method, including, but not limited to, snap-fit connection, bolts, rivets, welding, adhesive or epoxy. Other examples of adjustable keyboard tray 100 may include different slide configurations, including, but not limited to, linear rails with bearing slides, a top track with hanging roller sides, and a bottom track with roller slides.
A keyboard platform mount 131 is attached to each slidable rail 130 with a keyboard platform mount pivot 109. The keyboard platform 101 is attached to each keyboard platform mount 131, spanning the gap therebetween. The keyboard platform 101 is slidable relative to the clamps 104 via the slide 120 and tiltable relative to the slide 120 via the keyboard platform mount pivot 109. The slides 120 allow an operator to apply a force to move the keyboard platform 101 in a horizontal motion to locate the keyboard platform 101 closer to or further away from the operator. The slides 120 operate in parallel for horizontal adjustments the keyboard platform 101. Likewise, the keyboard platform mount pivots 109 operate in parallel for tilt adjustments of the keyboard platform 101.
The adjustable keyboard tray 100 further includes a tilt lock to fix a tilt setting of the keyboard platform 101 relative to the slide 120. The tilt lock includes a tilt locking thumb screw 107 including a threaded shaft extending through one of a plurality of holes 136 in the keyboard platform mount 131 and engaged with a threaded hole in the slidable rail 130. Each of the plurality of holes 136 provide a different preset tilt setting for the keyboard platform 101. An optional washer 108 over the threaded shaft of thumb screw 107 provides an interference fit thumb screw 107 and operates to protect the interface of the thumb screw 107 and the keyboard platform mount 131 at the selected hole 136.
In some examples, adjustable keyboard tray 100 may be sold as a kit without a separate desktop. Separate components in an example kit for adjustable keyboard tray 100 are shown in
The keyboard platform 101 includes two keyboard platform 101 sections 101A, 101B joined with connecting plates 102 that span a joint between the two keyboard platform 101 sections 101A, 101B along an underside of the keyboard platform 101. Other examples may include a unitary keyboard platform 101, rather than two keyboard platform sections 101A, 101B. The use of keyboard platform sections 101A, 101B facilitates a reduced overall package dimensions for the kit for adjustable keyboard tray 100 prior to final assembly by a customer. In some examples, a packaging size with a maximum box length of 18 inches may reduce shipping expenses compared to designs requiring larger packaging.
Tilting track 103B includes a slidable rail 130 attached to a keyboard platform mount 131 with a keyboard platform mount pivot 109. In the illustrated example, pivot 109 is formed from a rivet through holes in both slidable rail 130 and keyboard platform mount 131. Other pivot connections can also be used, such as, but not limited to, bolts and locknuts, pins, a solid axel protruding from one of slidable rail 130 or keyboard platform mount 131 and extending through a hole in the other, binding screw mated to a binding post through holes in both slidable rail 130 and keyboard platform mount 131, a linkage, such as a four-bar linkage, or other pivot connection.
The keyboard platform mount 131 is formed from a unitary sheet metal with a bend separating an upper mount section 132 from a rail section 133. The upper mount section 132 include screw holes 139 for mounting keyboard platform 101. The rail section 133 includes holes for pivot 109 and holes 136 for thumb screw 107. The rail section 133 also includes an elongated radial slot 134 to receive pivot limit screw 135. The thumb screw 107 and the pivot limit screw 135 engage threaded holes in slideable rail 130. To facilitate more refined adjustment, holes 136 for thumb screw 107 are aligned on two separate radii relative to pivot 109, the holes 136 at each radii are aligned with one of two threaded holes in in slideable rail 130. Slideable rail 130 includes recessed screw holes 138 to attach the channel track 113 (
Next, the assembly process includes securing adjustable keyboard tray 100 to the desktop 201 with clamps 104. Specifically, a user positions the clamps 104 over the edge of the desktop 201 and turns the hand screws 146 to tighten the clamps 104 to engage the edge of the desktop 201. With adjustable keyboard tray 100 secured to the desktop 201,
At the selected tilt position of the keyboard platform 101, the user aligns one of the holes 136 in the keyboard platform mount 131 and with a threaded hole in the slidable rail 130. For each tilting track 103, the user pushes then installs both thumb screws 107 through the aligned holes 136 into the threaded hole in the slidable rail 130 and tightens the thumb screws 107. The tilt of the keyboard platform 101 is locked by the thumb screws 107.
In an alternative example, tilt adjustment may include a friction lock, spring lock or pin lock rather than the screw lock through holes 136. In an example friction lock configuration, thumb screws 107 may extend through radial slots to provide infinite adjustment points for the tilt rather than the present tilt adjustments provided by holes 136. However, the use of holes 136 in the keyboard platform mount 131 (in combination with a screw, solid pin, or depressible spring pin), may provide more stability for the keyboard platform 101 at the selected the tilt adjustment than other examples utilizing a friction lock with a radial slot instead of holes 136.
The locked tilt adjustment provided by adjustable keyboard 100 allows users to set keyboard platform 101 at the most ergonomic position for their individual preferences and workspace.
Brackets 404 function as desk mounts to secure the adjustable keyboard tray 400 to the underside of a desktop, such as desktop 201 (
