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.

What is claimed is: 
     
         1 . A vertical workbench comprising a framework, a mobile structure, an L-shaped board and a fixing structure; wherein the framework comprises a slide rail, an elbow bracket and a base; a plurality of slide rails are provided; the slide rail comprises a linear slide rail and a rotary slide rail; the rotary slide rail is divided into a mobile slide rail and a fixed slide rail; the rotary slide rail comprises an upper semicircular slide rail, a lower semicircular slide rail, a circular slide rail and an outer frame slide rail; the outer frame slide rail comprises a closed type slide rail and a non-closed type slide rail; and the slide rail is provided with a plurality of clamping spaces; the elbow bracket is in a T shape; a cross bar of the T shape is a bracket and a vertical bar of the T shape is a supporting bracket; the elbow bracket comprises a mobile type elbow bracket provided with a groove and a fixed type elbow bracket; the L-shaped board, short for an L-shaped writing board, is of an axially symmetric structure; and on a left side and a right side of a front face thereof are respectively provided with a book clamping structure for adjusting width; a left side view is L-shaped; a long vertical bar on the left of the “L” is a writing board; a lower cross bar of the “L” is a lower bracket; and a short vertical bar on the right of the “L” is a limiting bracket; and a plurality of small holes are reserved in the L-shaped board; the fixing structure comprises a brake-clamping space structure, a connecting frame-clamping space structure and a “nut-bolt” structure; the brake-clamping space structure comprises a clip, a connecting frame, a return spring and a brake iron; the connecting frame-clamping space structure comprises a plurality of clamping spaces reserved on the L-shaped board, the rotary slide rail and the vertical slide rail and a plurality of connecting frames with different lengths; a nut and a bolt of the “nut-bolt” structure are both provided with or without threads; the vertical workbench comprises a desk top type and a floor type; the framework and the L-shaped board comprise a fixed integral type and a freely combined-separated type; and all combinations of components of this patent adopted to realize similar functions fall within the protection scope of this patent. 
     
     
         2 . A vertical desk or the vertical workbench according to  claim 1 , wherein the vertical desk is designed and manufactured with the same principle and similar structure as the vertical workbench; the brake-clamping space structure is preferably adopted as the fixing structure; and the writing board, an easel and a blackboard are designed and manufactured based on the same principle and similar structure.
