Definitions
- the present invention relates to portable and adjustable desks or support structures, and in particular, to a portable and adjustable desk or support structure permitting multiple user positions while supporting an object.
- Portable and/or foldable tables have existed to provide users with an easily foldable/unfoldable table structure that provides table surfaces for a wide variety of uses and purposes and convenience to the users. These tables may be typically used at places or locations where conventional tables cannot be used. Such tables are used for working, reading/writing, eating, or any other purposes. Common uses of such tables are for placing and supporting laptop or portable computers, books, plates, bowls, or any other such items.
- laptop or portable computers are used by various persons. Laptop computer users often prefer to use their portable computers while sitting in a comfortable chair/couch or while sitting up or lying in a bed. These locations, however, typically require a table or desk on which the computer is placed, or the user must position the computer on his or her lap.
- portable computer users generally prefer to use some type of portable table, stand, support device, or other flat, rigid surface upon which the computer is placed.
- leg assemblies for a table or support structure wherein the leg components stay coupled to the leg assembly and wherein the leg components are able to be put into a folding position and rotate or fold easily out of the way of each other when being folded to a compact storage position and are able to rotate back to an unfolding position for use.
- U.S. Pat. Nos. 2,449,492; 2,476,620; 3,805,710; 4,119,289; 4,726,556; 5,417,168 provide examples of such height adjustable tables or support structures.
- some of the prior art height adjustment mechanisms for these tables or support structures are cumbersome, awkward, or difficult to use.
- U.S. Pat. No. 5,417,168 discloses a height adjustment mechanism that uses an engaging protuberance to one of a number of height adjustment holes in order to adjust the height of each leg component.
- this height adjustment mechanism has the problem of aligning the engaging protuberance to a certain/desired height adjustment hole. Therefore, the need and desire exists to develop and provide a height adjustment mechanism for a table or support structure that is easily accessible and easy to use to adjust height of the table and able to easily align and engage the engaging protuberance into a certain desired height adjustment hole.
- a further limitation of the prior art tables or support structures is that they do not explicitly teach or disclose legs or leg components that are independently adjustable to conform the plane of the table or support struc ture surface to even and uneven surfaces (i.e. bed or mattress surface or any other such even/uneven surfaces).
- Another limitation of the prior art tables or support structures is that they do not adjust to the size and height of the user in that the width distance apart from the legs or leg components are not adjustable when the height of the table or support structure surface is lowered or raised.
- a mechanism for adjusting the angle or pitch of the table or support structure surface is in continual need of improvement and development. Therefore, the present invention discloses and provides a portable and configurable desk top to enable multiple user positions that overcomes the above problems, disadvantages, and limitations of the prior art.
