The present invention relates to adjustable tables, and more particularly, to an adjustable table provided with adjustable inclined angle and table height.
Tables and chairs are commonly applied by people for various purposes. For example, a table and at least a chair are usually required for facilitating demands of dining, document processing, or office operation. In addition, the time of people applying tables and chairs is relatively long nowadays. In case the height of the table and the chair mismatches the body shape of the user, the user might feel body pain or limbs ache after using the table and chair for a long period. Therefore, sizes of the table and chair are in direct relation to the body shape of the user.
However, most of the tables presently available are provided with a fixed side, so that the size is not able to be adjusted based on different users demand, failing to meet the ergonomics. Also, regarding to a recently provided adjustable table in the market, one of the inclined angle and the table height is able to be adjusted; however, such adjustable tables are only able to partially resolve the issue for the user, with other disadvantages and inconveniences remaining to be improved.
Therefore, a table provided with an adjustable inclined angle and table height is needed for meeting the demand of users with different body shapes.
For improving the issues above, an adjustable table provided with adjustable inclined angle and table height is disclosed. With a first support rack pivotally swaying against the foot, height of the table board is adjustable; with a second support rack pivotally swaying against the first support rack, the inclination of the table board is adjustable. Therefore, both the height and the inclination of the table are allowed to be adjusted, facilitating the utility of the table.
For achieving the aforementioned objectives, an embodiment of the present invention provides a table with adjustable height and inclination, comprising:
a foot;
a first support rack clutchably and pivotally combined with the foot;
a second support rack clutchably and pivotally combined with the first support rack, the second support rack also fixed to a table board;
a first positioning assembly disposed at a location of the pivotal combination between the first support rack and the foot, the first positioning assembly moving between a fastened status and a loosened status to vary a status of a pivotal combination between the first support rack and the foot so as to adjust and fix an angle of the first support rack swaying against the foot; and
a second positioning assembly disposed at a location of the pivotal combination between the first support rack and the second support rack, the second positioning assembly moving between a fastened status and a loosened status to vary a status of a pivotal combination between the first support rack and the second support rack so as to adjust and fix an angle of the second support rack swaying against the first support rack.
With such configuration, user is able to adjust the table inclination based on different user demands by swaying the second support rack against the first support rack. Also, user is able to sway the first support rack against the foot for adjusting the table height against the ground. Therefore, utility of the table provided by the present invention is enhanced.
