Abstract

A turning bead type keyboard tray is characterized in that a rectangular frame is arranged on the lower side of a keyboard, a plurality of inner holes which do not run through the frame wall and are used for retaining vertical columns are correspondingly arranged at the positions, close to the upper edge, on the inner sides of an upper border and a lower border of the rectangular frame, and the turning beads provided with through holes at the centers penetrate on the vertical columns. A user can put a wrist on the turning beads and use the turning beads to rotate to realize smooth left-and-right translation, thereby reducing fatigue of arms and wrists, the tray can be integrated with the keyboard via injection molding and also can be formed singularly, and is widely applicable to computer users spending a long period of time on inputting or in use of the keyboard.

Description

The rotary bead type keyboard tray

Technical field the utility model discloses a kind of rotary bead type keyboard tray, belongs to the computor-keyboard servicing unit.

Background technology has keyboard now, have the band pallet, not with pallet and ergonomic keyboard.With the wrist fatiguability of pallet, the pellet type keyboard can not alleviated wrist fatigue, and ergonomic keyboard and round trip flight swallow keyboard need not crooked wrists, can reduce wrist fatigue effectively, but will knock editor's keypad, keypad area, must lift arm and move.For a large amount of input users, need a kind of pallet that need not raise one's hand arm continually to reduce the fatigue of arm and wrist.

Summary of the invention the utility model can be realized this purpose effectively, can reduce the fatigue of arm and wrist.

The utility model is achieved in that establishes the rectangle framework below keyboard, lower frame is inboard thereon establishes some open interiors that do not penetrate the frame wall with the clamping column near place, upper edge correspondence position, and the ball center is established through hole and is through on the column.Wrist is placed on the ball, utilize the rotation of ball to realize about easily translation, can reduce the fatigue of arm and wrist.

Description of drawings specifies structure of the present utility model and principle of work below in conjunction with accompanying drawing.Accompanying drawing is a synoptic diagram, wherein: 1 framework, 2 upper ledges, 3 lower frames, 4 open interiors, 5 columns, 6 balls.

Embodiment as shown in the figure, the utility model is to establish rectangle framework 1 below keyboard, frame 2 and place, lower frame 3 inboard close upper edge correspondence position are established some open interiors 4 that do not penetrate the frame wall with clamping column 5 thereon, and ball 6 centers are established through hole and are through on the column 5.All balls 6 constitute holding tray surface.Wrist suffered friction force of slip on existing keyboard tray is bigger, need lift arm and move.Rolling friction force rate force of sliding friction is little, uses the utility model, and wrist is placed on the ball 6, utilize the rotation of ball 6 to realize about easily translation, the arm of need not raising one's hand has reduced the fatigue of arm and wrist.Column 5 should be selected relatively hard materials such as smooth metal rod or engineering plastics for use.Ball 6 can be selected the little materials of friction force such as plastics, resin for use, and ball 6 also can be designed to abacus bead formula oblateness or be connected as a single entity be right cylinder, and its part that exceeds framework 1 is less than ball 6 radiuses.The size of ball 6 should guarantee light rotation make again adjacent two the string balls 6 between the slit be unlikely to wide dark excessively, in order to avoid wrist jolts.Therefore, ball 6 diameters are preferably in 0.7-1.6CM, and the little 1-3CM of distance is convenient to the wrist pressure zone and ball 6 and slide up and down between also comparable upper ledge 2 of every string ball 6 width and the lower frame 3, conveniently knocks the square key position.Pallet and keyboard are isometric, contour, can mould with keyboard to be cast as one, and also moulding separately is with the supporting use of keyboard of a large amount of pallet-frees on the market.

The utility model compact conformation, convenient and practical, easy to implement is widely used in a large amount of inputs or the long-time computer user that uses.

Claims
