The present invention generally relates to desks, and more particularly to a height-adjustable table.
Republic of China, Taiwan, Patent No. M599594, titled “Improved structure of lifting table,” discloses a height-adjustable table including a base, a tabletop, a connecting base, and a lifting device for the tabletop. The lifting device is composed of an inner tube, a hydraulic piston rod, a pulley seat, an outer tube, and a fixing sea, as revealed by the patent's
Although the aforementioned conventional height-adjustable table can solve the problems of wobbling and impact noise generation, its structure is complex with a large number of components, and there is still room for improvement.
Therefore, the present invention discloses a novel height-adjustable table, including a tabletop, a lifting member, a positioning member, a cushioning member, and a braking member. The lifting member includes a base and a lifting platform. The lifting platform is slidably telescoped within the base, and the lifting platform is connected to the tabletop. The positioning member is configured on the base. The cushioning member includes a first pulley, a second pulley, and an elastic piece. The first pulley and the second pulley are positioned inside the lifting platform. The elastic piece's two ends are respectively connected a first rope and a second rope. The first rope is wrapped around the first pulley, and the second rope is wrapped around the second pulley. The braking member is configured on the lifting member.
Specifically, the lifting member further includes a rail structure.
Specifically, the positioning member includes an operating piece and a locking piece. The operating piece is connected to the locking piece.
Specifically, the elastic piece is a spring.
Specifically, the braking member includes a number of brake pads and a lever piece. The brake pads are positioned within the lifting platform around the second pulley. The lever piece is connected to the brake pads.
As described above, the height-adjustable table utilizes the installation of the cushioning member to enable the lifting platform to smoothly ascend and descend relative to the base. Additionally, it uses the positioning member to lock the lifting platform at a desired position relative to the base. It also uses the braking member to stop the lifting platform from moving up and down.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
As shown in
The tabletop 1 can be one used for a computer desk, writing desk, dining table, or conference table.
The lifting member 2 includes a base 21 and a lifting platform 22, with the lifting platform 22 being slidably telescoped within the base 21. A top end of the lifting platform 22 is connected to a bottom side of the tabletop 1. The lifting member 2 is equipped with a rail structure 23, which includes multiple rails such as inner rails, outer rails, and intermediate rails. The outer rails are vertically fixed to an inner wall of the base 21, while the inner rails are vertically fixed to an outer surface of the lifting platform 22. The intermediate rails are slidably positioned between the outer rails and the inner rails so that intermediate rails and the inner rails may slide relative to the outer rails, thereby enabling the lifting platform 22 to move up and down relative to the base 21 and extending the lifting range of the lifting platform 22.

As described above, the height-adjustable table utilizes the installation of the cushioning member 4 to enable the lifting platform 22 to smoothly ascend and descend relative to the base 21. Additionally, it uses the positioning member 3 to lock the lifting platform 22 at a desired position relative to the base 21. It can also use the braking member 5 to stop the lifting platform 22 from moving up and down.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
