发明名称 Portable and adjustable table with improved leg assembly
摘要 An adjustable and portable table 10 with improved foldable leg assembly 20. The leg assembly 20 supports a table surface 12. The leg assembly 20 includes a mounting bar 18, a first angled leg component 40, and a second angled leg component 40. The second leg component 40 is able to rotate relative to at least a portion of the mounting bar 18 so that the second leg component 40 is out of a way of the first leg component 40 when the first and second leg components are being folded to the storage position. The first and second leg components 40 are able to be unfolded to a usable position. The mounting bar 18 further has a first bar portion 24 to which the first leg component 40 is coupled and a second bar portion 26 to which the second leg component 40 is coupled. The second bar portion 26 rotates relative to the first bar portion 24. The first bar portion 24 and the second bar portion 26 are able to be placed in rotational lock and unlock positions. Height adjustment components 64 with a hollow structure 65, an engaging protuberance 66, and a spring component 68 are each coupled to the leg components 40 to allow for height adjustment. The height adjustment components 40 allow for independent height adjustment of the leg components 40 to level a horizontal level plane of the mounting bar 18 when the leg components 40 are placed on even and uneven surfaces. The leg assembly 20 has a base distance width between the leg components 40 which increases as lengths of the leg components 40 increase and decreases as the lengths of the leg components 40 decrease. A table adjustment mechanism 25, which includes at least one adjustment knob, a washer ring, and at least one friction plate having a concave friction surface, allows angular and pitch adjustment of the table surface 12 coupled to the mounting bar 18.
