This invention relates generally to lap desks and particularly to lap desks adapted for use with hand-held electronic devices. More particularly, this invention relates to a lap desk having built into its work surface a mouse pad and a slotted port for holding upright said electronic device. Still more particularly, this invention relates to a mouse pad and slotted port module which may be applied to any planar surface.
Lap desks commonly comprise planar, rigid, often rectangular, portable work platforms adapted to rest in a user's lap and to support books, writing pads, electronic devices or the like. Lap desks also commonly include padding on their bottom sides to enhance user comfort while the weight of the lap desk and objects bears upon the user's lap. While using multiple objects together, such as a writing pad and an electronic device, the lap desk work surface can become somewhat crowded. Increasing the work surface area has practical limits imposed by the size is the user's lap or the seat in which the user rests. Means for more efficient use of lap desk work surface space would mitigate such problems.
Recently developed electronic devices such as tablet computers, game machine controllers and cellular telephones are comparatively thin in cross section. They seldom come equipped with stands or props for holding them upright, however, causing them to occupy a disproportionate share of the lap desk work surface. A lap desk with a slot adapted to cradle an edge of such an electronic device and hold it upright would retain the electronic device on the work surface without consuming substantial lap desk work surface space.
Lap desks often also are used with laptop computers employing a separate, movable pointing device such as a mouse. A computer mouse detects horizontal movement and translates it to movement of an indicator icon on the laptop screen. It does so using either a roller ball or a laser light beam extending downward from the bottom of the mouse toward a resting surface. The roller ball must engage a surface having sufficient friction to turn the ball, a trait the relatively smooth, hard finish of most work surfaces, including lap desks, usually lacks. The laser must point toward an opaque surface which minimizes unnecessary light scatter. In either case, users commonly carry a separate mouse pad which must be stored separately and often can become lost or damaged. A lap desk with a built in mouse pad would relieve users of the burden of providing and keeping track of a separate mouse pad.
Medium density fibreboard (MDF) is an engineered wood product made from hardwood or softwood fibers combined with wax and a resin binder by applying high temperature and pressure to form panels. It is stronger and much denser than particle board, and makes a durable panel for lap desks. MDF also often is covered in PVC to harden its planar surface for some applications, including lap desks. MDF is, however, difficult to cut smoothly for slots and holes, and PVC cannot easily be folded smoothly into a cutout in the MDF. A need exists for an insert bearing a flange which can smooth out irregularities in slots cut into MDF, and which can secure the edges of PVC coatings on MDF. Such module also can be used to insert a slot and mouse pad into any planar surface.
A lap desk includes within its planar work surface a mouse pad and a slotted port for securing an electronic device such as a tablet, e-reader or cellular telephone in an upright and useable position. The mouse pad is substantially flush with the work surface and disposed in a right hand or left hand position for right- or left-handed users. The slotted port is inclined slightly so that the user can view and engage the device's screen while working with other objects on the lap desk. The slotted port may vary in width for electronic devices of various sizes; its depth and thickness accommodating most hand-held electronic devices without obscuring their screens. In one embodiment, the mouse pad and slotted port are molded into a module bearing a flange which can be inserted into a congruently sized aperture in any surface.
The novel features believed characteristic of the present invention may be set forth in appended claims. The invention itself, as well as a preferred mode of use and further objects and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
Referring now to the figures, and particularly to
Opposite and co-extensive with top deck work surface 11, deck bottom 12 preferably includes one or more protrusions 15 designed to stabilize lap desk 10 while it rests on a support surface 5 such as a tabletop (
Turning now also to
Surface 23 of mouse pad 20 comprises a material having sufficient roughness to provide a roller ball mouse 1 with enough friction to operate efficiently. Further, surface 23 preferably is opaque and absorbent of most laser light frequencies to a degree to provide a laser mouse 1 with the necessary reflection to operate efficiently, but absorbent enough in the relevant light frequencies to dampen unnecessary light backscatter. A suitable material for surface 23 is a rough molded polyethylene available commonly. One having ordinary skill in the art will recognize that surface 23 could be rubber, cloth, a rough paint, or any other material having a rough enough texture and opacity for operating mouse 1 of either design.
Referring now specifically to
As best seen in
Device port 30 extends for its length across the top of mouse pad 20 parallel to rear edge 18 for substantially the entire width of mouse pad 20. The length of slotted port 30 is selected to admit electronic device 3, in this case a cellular telephone, in either an upright or sideways (not shown) orientation. One having ordinary skill in the art will recognize that any length of slotted port 30 sufficient to hold electronic device 3 of a size selected for the application is considered to be within the spirit and scope of the present invention. For example, slotted port 30 depicted in the figures is of sufficient size to hold most cellular telephones and perhaps a small e-reader or tablet. Slotted port 30 could, however, be of a length (not shown) sufficient to hold a full size tablet or e-reader such as an iPad (full size) available from Apple Corporation of Cupertino, Calif. USA.
In operation, a user (not shown) would place lap desk 10 on a support surface or his lap, with front edge 17 adjacent the user and work surface 11 tilted slightly toward the user because of the differential sizes of protrusions 15. The user then would place electronic device 3 within port 30 and turn it on for viewing its screen and for manipulation and operation thereof as desired. The user also would place whatever objects desired upon the remainder of work surface 11 and proceed to use them. If those objects include a laptop computer (not shown), the user may connect mouse 1 thereto and place mouse 1 on mouse pad 20 for control of said laptop computer. The user would reverse the foregoing steps, though not necessarily in order, to complete the operation.
While the invention has been particularly shown and described with reference to preferred and alternate embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention. For example, as discussed and illustrated, slotted port 30 forms an integral part of an insert that includes mouse pad 20, but slotted port 30 instead could be a separate component and feature of lap desk 10 and disposed at any location within the delimited region of work surface 11. Further, though depicted and described with only one mouse pad 20 and slotted port 30, selected and positioned for left- or right-handed users, lap desk 10 could include both, including duplicate ports 30 associated with each mouse pad 20.
