Portable And Adjustable Desk

Abstract

Disclosed herein is a portable, adjustable, and foldable desk for using laptop computers or reading books in bed. The apparatus comprises a flat upper panel attached to leg assemblies at first lockable joints, and joint locks. The flat upper panel is freely rotatable about the first lockable joints on unlocking the first lockable joints for adjusting angle of the flat upper panel. Each of the leg assemblies comprises leg segments interconnected at second lockable joints. The leg segments are freely rotatable about the second lockable joints on unlocking the second lockable joints for adjusting height of the leg assemblies. The joint locks lock the first lockable joints and the second lockable joints. Each joint lock comprises a first friction plate, a second friction plate, a washer, and a locking button. The locking button locks the first friction plate, the second friction plate, and the washer using a pushing force.

Description

BACKGROUND[0001]This invention, in general, relates to foldable furniture. More specifically, this invention relates to a portable apparatus for providing an adjustable activity surface.[0002]People often check emails using a laptop computer, or read a book in bed shortly before sleeping or soon after waking up. Typically the laptop computer or the book is positioned on the user's lap. The user needs to make an effort to balance the laptop computer or the book or view the screen of the laptop computer from a proper viewing angle, which often causes discomfort, for example, fatigue and pain of the hands, wrists, arms, neck, and legs.[0003]Different desks or support devices are used in an attempt to alleviate these discomforts. Some support devices may use non-skid rubber material on the top surface to grip the laptop computer. A computer desk may be supported on web strapping that passes over the legs of a seated user. However, the height of the computer desk is generally not adjusta...

AI Technical Summary

Benefits of technology

[0008]The first friction plate comprises an elongate shaft extending outward from the first friction plate. The second friction plate comprises an opening for passing the elongate shaft. The washer is sandwiched between the first friction plate and the second friction plate. The washer comprises an opening for passing the elongate shaft. The washer prevents relative motion between the first friction plate and the second friction plate.

[0011]The free rotation about the first lockable joints and the second lockable joints enables adjustment of angle of the flat upper panel and height of the leg segments respectively for the adjustable activity surface.

Problems solved by technology

The user needs to make an effort to balance the laptop computer or the book or view the screen of the laptop computer from a proper viewing angle, which often causes discomfort, for example, fatigue and pain of the hands, wrists, arms, neck, and legs.

However, the height of the computer desk is generally not adjustable and any movement of the legs of the user might cause the laptop computer to slide to an undesirable position.

However, adjusting the height and the angle are complicated and take time.

Furthermore, there is no provision for the user to rest their wrist on the table surface.
