1. Technical Field
The present disclosure relates to working surfaces tilted for operator's convenience.
2. Description of the Related Art
Personnel such as draftsmen may work on a raised board, but if the desk is positioned at only a fixed angle, long time operation may cause discomfort the neck and the cervical vertebrae of the operator.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
The operation plate 10 includes a stop bar 12 along the base plate 20. The operation plate 10 is rotationally connected to the base plate 20. In the embodiment, the operation plate 10 is connected the base plate 20 via two hinges 25 fixed to ends of the operation plate 10 and the base plate 20.
The sliding rail 30 includes a rail 32 and two clamping pieces 34. The rail 32 and two clamping pieces 34 are all fixed on the base plate 20. The two clamping pieces 34 are parallel to each other with the rail 32 between them. Each clamping piece 34 defines a number of slots 38. The number of slots 38 face the rail 32 and are perpendicular to the base plate 20.
Also referring to
The adjustment member 50 defines a through hole 56 perpendicular to the clamping piece 34. An elastic member 60 is received in the through hole 56. Two clips 70 are respectively positioned at two ends of the elastic member 60 and partly received in the through hole 56. The end of the clip 70 exposed at the through hole 56 is received in one of the slots 38. The two clips 70 overcome the elastic force of the elastic member 60 in moving from one slot 38 to another slot 38 when the adjustment member 50 slides along the rail 32, and such moving changes the angle between the operation plate 10 and base plate 20.
In the embodiment, a handle 80 protrudes from the adjustment member 50. An operator pushing on the handle 80 makes the adjustment member 50 slide along the rail 32.
It is understood that the present disclosure may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the disclosure is not to be limited to the details given herein.
