Technical field

The present invention relates to a table, in particular, a table that can be installed on the side of a chair, bed, sofa, table, pulley chassis or one-piece chair and can be easily adjusted in angle or position for the convenience of the user. desktop.

Background technique

General chairs, especially chairs for students in classrooms, and even beds or sofas, etc., when the user is sitting but wants to write, operate electronic devices or even place items such as drink cups, these chairs Furniture, bed or sofa, etc. are not equipped with a table such as a writing tablet, causing inconvenience. Although there are existing structural designs with a desk attached in the field of chairs, such as US9,044,099 "CHAIR WITH ADJUSTABLE TABLET", however, the writing desk disclosed therein has the following shortcomings:

(1) The writing tablet is designed to be installed only on a specific chair, which relatively limits the application scope of the writing tablet and is not conducive to manufacturing and consumption.

(2) The writing table uses a sliding member to slide in a sliding groove inside the table to adjust the left and right horizontal position of the table. This relatively increases the friction of the sliding, which is not conducive to the operation of the consumer or the user. Convenience, and each component is also easily damaged due to large friction.

(3) The writing desk is supported on the upper end of a pole for horizontal rotation. However, there is no positioning device between the desk and the upper end of the pole, making the desk unable to be adjusted after operation. The positioning state is formed relative to the upper end of the support rod. Even if the user cannot position the writing desk at the desired applicable angle or position after adjustment, it will cause inconvenience to the user.

(4) The writing tablet uses two sets of upper and lower bearings (upper bearing 66 and lower bearing 68 as shown in Figure 3) to rotate. The components are relatively complex and easily damaged, and are not conducive to manufacturing or consumption. end-of-life assembly operations or reduce manufacturing costs.
