VERTICAL WORKBENCH

Abstract

Disclosed is a vertical workbench, including a framework (3), a mobile structure (10), an L-shaped board (1) and a fixing structure. The framework (3) includes a slide rail (2), an elbow bracket and a base (4). The slide rail (2) includes a linear slide rail, semicircular slide rails (7, 8), a circular slide rail (9) and an outer frame slide rail (11). The L-shaped board (1), short for L-shaped writing board, is of an axially symmetrical structure, and is provided on each of the left and right sides of the front face with a width-adjustable book clamping structure. The fixing structure includes a brake-clamping space structure, a connecting frame-clamping space structure, and a nut-bolt structure. The vertical workbench enables a person to naturally maintain the correct reading and writing posture to overcome the disadvantages of traditional tools.

DETAILED DESCRIPTION

[0039] Some embodiments of the present invention are described below, which are not intended to limit the protection scope of the present invention and have the same principle and similar methods. Other functions added based on the patent of the present invention without substantial differences shall also fall within the protection scope of the present invention. All kinds of combinations that use the components mentioned in this patent to achieve similar functions fall within the protection scope of this patent, and many of them are too cumbersome to list. The optimal solution (6) is taken as an example, in which a vertical slide rail has a rotary slide rail thereon, and which has a left and right symmetrical structure.

[0040] 1. Vertical workbench with small size used on the desk top: the vertical workbench is fixed on the desk top through the base of the framework as required, with the length of the upper arm as a reference in the front-back direction; a person maintains the correct posture to determine the height of the eye, and then adjusts the L-shaped board and the mobile rotary slide rail to the height corresponding to the eye through the linear slide rail in the up and down direction; an inclination angle of the L-shaped board is adjusted through the rotary slide rail; the L-shaped board is fixed after the height and angle of the L-shaped board are all determined; and a book is fixed on the L-shaped board through the book clamping structure, and the elbow bracket is adjusted to a proper height to be fixed. In this way, the person can work and study in the right posture. After a certain period of time, free adjustment can be made between the sitting posture and the standing posture by adjusting the height of the vertical workbench.

[0041] Two L-shaped boards are needed when it comes to copying: the front L-shaped board can be moved left and right and fixed, so as to facilitate turning over the book on the rear L-shaped board.

[0042] 2. It is more convenient to move a desk with a larger size with two hands, and it is better to use the brake-clamping space structure. The clip is set in place by holding the clip while grasping the desk with the hands or by stepping on the clip with feet, i.e. to control the clip with the feet. There is little difference between the desk and the vertical workbench in other aspects.
