It can be used in computer tablets and notebook computer etc. making common writing tablet the ideal computer operation desk.
Description
The invention belongs to the computer appurtenance, relate to a kind of device of adjusting position of computer keyboard.
During operating computer, except sitting posture, whether the position of operator's eye, hand, wrist, arm is suitable, very big to the level of comfort influence of operator's body posture.Corresponding, the position of the indicator screen of computer, keyboard and mouse also just need meet the requirement of ergonomics as far as possible.
The display of present desktop computer, keyboard and mouse all are independent parts, and its position is in use decided by the physical dimension of the worktable case of carrying these parts substantially.Before common PC computer was born and popularizes, the use of various desks, table was very general.The terrain clearance of the desktop of the desk of standard, table is generally all between 75 to 78 centimetres, and this calibrated altitude is to require to set according to the bend over the desk comfortableness of read-write posture of common people.And the desirable posture of operating computer has very big difference with the desirable posture of bending over the desk to read and write.According to principle of human engineering, the terrain clearance standard at the indicator screen center of computer should be about 100 centimetres, and should be lower than operator's eyes look squarely line [S1] (referring to Fig. 1).The bottom surface of keytop of keyboard [S2] and mouse should be apart from about 65 centimetres on ground.
If display is placed on the common desk, the terrain clearance of indicator screen can meet the requirements basically.But if keyboard and mouse are placed on the desk, the terrain clearance of the keytop of keyboard and mouse bottom surface will reach respectively about 80 centimetres and about 78 centimetres, considerably beyond reasonable altitudes.The user can be forced to arm is raised with refusing to budge for a long time unsettled, with very uncomfortable posture operation keyboard and mouse.Finger, the position of wrist and the requirement that attitude does not meet operation keyboard yet, the as easy as rolling off a log fatigue that causes, and can cause relevant disease.
Therefore, in order to obtain more rational computation environment, various computer desks, platform have appearred on the market.Various computer tables' common feature is to provide the placement location of a terrain clearance about 65 centimetres for keyboard.That is to say very why the various desks of Pu Jiing, desk are not suitable for serving as the computer tables, its basic reason only is the correct position that the common table that writes is not placed keyboard.In the general family, the shared position of original desk often is exactly the position of the most suitable placement computer.Therefore, most of area of residences and hard up user have bought after the computer, often have to consider whether to remove or eliminate original certain desk, table, for computer desk is vacateed a no small space, and the generation of this unnecessary expense, waste and trouble only is because original desk does not have suitable keyboard position.In fact, from the furniture functions angle, the big table top of common desk, high capacity, many drawers and good stable and firmness aspect all have more practical value than existing most of computer tables.Just because of this, in many occasions, the user who has bought modern high-end computer equipment is for fear of waste and trouble, also in order to keep the advantage of original desk, table, though often use original common desk, desk to serve as computer desk---and very uncomfortable when operating computer.In addition, in some special occasions, existing computer desk also is not easy to be accepted.Such as, the personal computer that office is responsible for often would rather be placed on top class in a kindergarten's platform of luxurious style---because computer desk is difficult to show this style.The keyboard and the mouse that just are placed on top class in a kindergarten's platform use equally very uncomfortable.
Except the terrain clearance of display, keyboard and mouse need meet ergonomics requires, computor-keyboard and mouse also can have a strong impact on the comfortableness of computation posture with respect to the position relation of the horizontal direction of the dead ahead vertical plane (hereinafter to be referred as " human body central plane ") of user's human body centre symmetry line.
As described below, according to different computer application targets, the rational position relation of keyboard, mouse and human body central plane is different.
1, when mainly typewriting when operation, the center line of the space bar of keyboard [S3] should coincide with operator's human body central plane [S5] (referring to Fig. 2).Because the center line [S4] of existing computor-keyboard is in the right side of the center line [S3] of space bar 5 to 8 centimeters, this just requires keyboard to be offset 5 to 8 centimetres to the right side of human body central plane [S5].
2, when hocketing frequent typewriting and mouse action, needs (for example use the software of ACADCAD and so on to carry out design effort), not only require the center line [S3] of the space bar of keyboard to coincide with operator's human body central plane [S5], and, because the operator needs continually the right hand is moved around between the alphabetical keypad of keyboard and mouse, in order to reduce movement range and intensity, the alphabetical keypad that also needs mouse and keyboard is as far as possible mutually near (referring to Fig. 3).
3, when main mouse-based operation, and it is regular when cooperating keyboard operation (for example using the software of CORELDRAW and so on to carry out design effort), require the position of mouse will be as far as possible to lie in right hand below before the armrest naturally near the operator, this position roughly is positioned at right side centimeters more than 20 of human body central plane [S5], and the center line of the space bar of keyboard [S3] can be offset (referring to Fig. 4) to the left side of human body central plane [S5].
4, when mouse-based operation basically (for example surfing the web), then require the position of mouse should be more near human body central plane [S5], keyboard then can be offset farther (referring to Fig. 5) left.
The contrast above-mentioned requirements is analyzed existing computer tables, will find that existing computer tables and computor-keyboard structurally have following unreasonable part:
1, because present computer tables' Keyboard supporting board is general all according to the Design of length of keyboard, when the keyboard center is placed on the supporting plate, display center line [S6], human body central plane [S5], keyboard center line [S4] overlap, but the space bar center line [S3] of keyboard is skew left obviously, does not meet the requirement (referring to Fig. 6) of typewriting operation.Usually need to move keyboard during use, adjust the position of its left and right directions, perhaps adjust the tables and chairs position and revise.
2, the auxiliary bond district of QWERTY keyboard (directionkeys, numeric keypad) occupied a bulk of position on alphabetical keypad right side, and this position is placed the optimum position of mouse just.Therefore, though existing many computer tables' Keyboard supporting board do broad, reserved the position of Mouse pad on the right side, yet, when needs hocketed frequent typewriting and mouse action, the alphabetical keypad of keyboard and the distance of mouse were still far away excessively (referring to Fig. 7).And, in order to satisfy the typewriting requirement, the space bar position of keyboard moved to human body central plane [S5] after, the position of mouse is but farther apart from rational position, the operator need stretch out right arm out and away and remove to operate mouse.This moment, some related muscles joints of human body were in the spasticity of overstrain, the time slightly length will produce fatigue, have a strong impact on health and work efficiency.
3, existing computer desk platform has three kinds of Mouse pad placement locations basically: a kind of is the length that prolongs the left and right directions of Keyboard supporting board, keyboard placed side by side and mouse pad; Another kind is that the Keyboard supporting board left and right directions is narrower, does not perhaps have special-purpose Keyboard supporting board at all, and Mouse pad can only be placed on the desktop.Also have a kind of telescopic platelet that below the right side of Keyboard supporting board, is provided with, be used for placing Mouse pad.Wherein, first kind of mode be not owing to solve the position contradiction of keyboard and mouse, and when keyboard was adjusted to correct position, mouse position was offset too to the right; Otherwise, after mouse position is suitable, the serious again left avertence of keyboard.Both can't take into account (referring to Fig. 8).The second way does not then meet the basic operation posture requirement of mouse.Mouse is placed on the desktop not only high but also far away, and operator's arm is obviously understood fast fatiguing (referring to Fig. 9).If things go on like this, certainly can be diseases induced.In fact, at present based on the various computer operating systems of windows and most computer software all highly menuization, toolbarization, the usage frequency of mouse is high, and whether suitable mouse position comfortableness and the human body health to the computer operator is most important.The third mode does not only solve the major defect of first kind of mode, and, mouse position is reduced to liftoff below 60 centimetres, be lower than the tables and chairs handrail, more increased locational irrationality.Therefore as can be seen, the most rational status requirement of operation mouse is not all satisfied in the position of the Mouse pad under above-mentioned three kinds of modes.
In sum, existing common problem of writing table and the existence of computer table can be summarized as following 2 points:
1, the existing common table that writes is not suitable for directly serving as the computer desk case;
2, the structure of existing computer desk case fails to solve the contradiction between keyboard position and the mouse position with taking into account;
At the defective of aforesaid prior art, first purpose of the present invention is to solve the defective that common desk case is not placed the correct position of keyboard, and a kind of device of the adjustment position of computer keyboard based on common desk, desk is provided;
On the basis of realizing first purpose, second purpose of the present invention is to solve the defective that existing computer desk case can not be taken into account keyboard and mouse position requirement well, provide a kind of keyboard and mouse all can obtain rational deployment, more meet the requirement of ergonomics, and based on the device of the adjustment position of computer keyboard of common desk, desk;
Further purpose of the present invention is to make the structure of computer equipment itself that the rational location layout of keyboard, mouse and display can be provided effectively, and forms the computation environment that meets the ergonomics requirement.
First purpose of the present invention is achieved in that
This is a kind of device of adjusting position of computer keyboard, it is characterized in that: its necessary parts are only by can being placed in pedestal [100] on the desktop shape object [Z], being used to bear the Keyboard supporting board [200] of keyboard, and the coupling mechanism [300] that is connected between pedestal [100] and the Keyboard supporting board [200] constitutes; Keyboard supporting board [200] can done the compound mobile of vertical and horizontal direction between higher and lower two extreme positions [V1] [V2] under the restriction of above-mentioned coupling mechanism [300]; The Keyboard supporting board [200] that is moved to higher extreme position [V1] is positioned at the top of base bottom surface [S7], the Keyboard supporting board [200] that is moved to low extreme position [V2] is positioned at the front lower place of base bottom surface [S7], just near the above-knee position of computer operator, and be in plateau under the support of above-mentioned coupling mechanism [300], its minimum part is lower than at least 7 centimetres of base bottom surface [S7].
Above-mentioned feature can be with reference to Figure 10, and this is a synoptic diagram of describing basic design of the present invention.
Alleged " the desktop shape object " of this paper is meant that desk, desk, worktable, exhibition booth, sales counter, service desk, cashier, desk or the like are to have the object that tabular end face is a feature.
According to above-mentioned feature, when Keyboard supporting board was moved to low extreme position, keyboard was in serviceable condition, and its below is unsettled, and relies on the support of coupling mechanism, can bear the normal pressure that keyboard operation person applies.Because the desktop standard terrain clearance of desktop shape objects such as general desk, desk, desk is about 76 centimetres, therefore, the terrain clearance that is moved to the Keyboard supporting board of low extreme position is below 69 centimetres; This state is near the reasonable user mode of Keyboard supporting board.
Above-mentioned " base bottom surface " is meant the contacted part of desktop of the desktop shape object of pedestal and bearing base.If display is placed on the pedestal, the weight of display will help the stable of pedestal.In order to reach higher firmness, it is feasible conventional method that pedestal is linked to each other with web member with described ground desktop shape object.But because the weight of present kinescope class display is very big, and the position of display is positioned at the rear portion of desktop shape object, and therefore, utilizing the weight of display to come balance and stabilizing base and Keyboard supporting board also is the method for simple possible.Above-mentioned concrete structure that is connected the coupling mechanism between pedestal and the Keyboard supporting board and effect can utilize multiple routine techniques (for example jointed connecting rod) to realize.In described many embodiments in this paper back and accompanying drawing thereof, can see various implementation.
On above-mentioned feature base,, the invention allows for following two technical characterictics in order to realize second purpose of the present invention:
At first, described Keyboard supporting board rely on and above-mentioned coupling mechanism between sliding matching structure, can in being not less than 6 centimetres scope, be moved back and forth by the left and right directions along keyboard operation person.Like this, keyboard operation person can be at any time move left and right Keyboard supporting board as required, adjust the position of the left and right directions of keyboard like a cork, make keyboard position more meet the comfortableness requirement.
Further feature is to have proposed " mouse floating platform " feature: just unsettled and can be by the platform that is used for placing mouse of move left and right below the right side of described Keyboard supporting board increases by one, after having placed computor-keyboard on the Keyboard supporting board that is positioned at low extreme position, this platform will hide the part button of keyboard in the limit on the left position, for example direction keypad and numeric keypad district will not hide the button on the keyboard in the limit on the right-right-hand limit position.Like this, the backing plate of mouse just can have been used the space above the keypad of the right side of keyboard.Facts have proved that in the keyboard operation process, the numeric keypad district even the direction keypad of keyboard often can not be used for a long time.At this moment, the mouse floating platform is placed on these two keypads, will significantly improve the position of mouse.When needs, can very promptly remove the mouse floating platform, appear the keypad of crested.The unsettled height in the below of mouse floating platform should be determined according to the thickness on the right side of common keyboard certainly, be generally about 3.5 centimetres.Mouse floating platform table top is a little more than the key face height of keyboard, and this is a reasonable altitudes of placing mouse.
Because the one-piece construction of the device of the adjustment position of computer keyboard that the present invention proposes can be compressed quite compactly, and volume is little, therefore, can realize the 3rd purpose of the present invention by following feature:
Keyboard supporting board and computor-keyboard are combined as a whole.The necessary parts of keyboard just are installed in the inside of Keyboard supporting board, keypad are set at the upper surface of Keyboard supporting board.Certainly, the top still can be provided with the mouse floating platform.
Further, also can or all be combined as a whole the part in other equipment such as pedestal and computer monitor, mainframe box, audio amplifier.Like this, just formed a kind of New-type computer all-in-one, this all-in-one not only possesses the due function of computer, and, also carry the computation environment that meets the ergonomics requirement, the table shape thing of desk and so on can have been become computation platform rational in infrastructure immediately.The device of the adjustment position of computer keyboard that the present invention is proposed combines with notebook computer, can make the keyboard position of notebook computer can meet the requirement of ergonomics.
Other features of the present invention will further be introduced in the embodiment of back in conjunction with the accompanying drawings.
First advantage of the device of the adjustment position of computer keyboard that the present invention proposes is directly to utilize existing various desktop shape object, form the complete computation environment that meets the ergonomics requirement easily, make common desk can become satisfactory computation platform simply.
On the basis of above-mentioned advantage, second advantage of the device of the adjustment position of computer keyboard that the present invention proposes be proposed can transverse moving left and right Keyboard supporting board and mouse floating platform, solved the contradiction of keyboard and mouse position effectively, make the operator in various operation purpose, can both obtain the most rational keyboard and mouse layout by adjustment easily, help Optimizing operation person's working environment, work efficiency and human body health.
Further, another advantage of the present invention is to mutually combine with part or whole computer equipment by the device that will adjust position of computer keyboard, formed the integrated computer equipment of compact conformation, made this integrated computer equipment itself form the computation environment that meets the ergonomics requirement by existing common desk.

Referring to Figure 10, one of common purpose of the various specific embodiments of the device of the adjustment position of computer keyboard that the present invention proposes, it is exactly effect by certain effective coupling mechanism [300], allow and pilot operationp person moves to the front lower place of desktop shape object [Z] with Keyboard supporting board [200] by desktop shape object [Z] top position [V1] with hand, just the operator above the knee, the most rational job position [V2] of about 65 centimeters of terrain clearance.According to different application schemes, pedestal [100] and connect pedestal [100] and the concrete structure of the coupling mechanism [300] of Keyboard supporting board [200], shape, suitable material and size difference very big.
Figure 11 to Figure 13 has introduced first kind of embodiment.Its pedestal [100] that is placed on the common desk [Z] is thick about one a centimetre plank.The postmedian of pedestal [100] is placed display [X].The axle bed [304] that each side has two front and back to arrange at pedestal [100].Each axle bed [304] is gone up each hinged fork [302].The lower forearm of a tressel made from bending pipes [301] is fixedly connected on the below of Keyboard supporting board [200], and higher postbrachium and above-mentioned four forks [302] are hinged.The fork of the same side [302] is also respectively hinged with a translation connecting rod [303] that prevents the dead angle.
Above-mentioned tressel [301], fork [302], translation connecting rod [303] and axle bed [304] have constituted the coupling mechanism [300] that is connected pedestal [100] and Keyboard supporting board [200] jointly.
Keyboard drawer [200] can move to the use location from desk [Z] top by the operator under the acting in conjunction of above-mentioned coupling mechanism [300].Keyboard supporting board among Figure 11 [200] is in higher extreme position, just reclaims state; Keyboard supporting board among Figure 13 [200] is in low extreme position, just user mode; Keyboard supporting board among Figure 12 [200] is in the moving process.In moving process, because Keyboard supporting board [200] can be in horizontality all the time, so keyboard [J] can not fall down.Because there is about 18 centimetres difference in height in the front and back arm of tressel [301], behind the thickness of deduction pipe diameter and keyboard, supporting plate, the key face terrain clearance of the keyboard [J] that moves to user mode is reduced to about 65 centimetres, than low about 12 centimetres of about 77 centimetres height of writing surface.This highly is the ideal height that common adult uses computor-keyboard.Under the support with the coupling mechanism with enough firmness [300], the Keyboard supporting board [200] that moves to user mode can bear the normal pressure that applies when the operator uses.The weight of pedestal [100] itself adds the weight of the display [X] on it, can make Keyboard supporting board [200] can bear about 10 kilograms pressure.Certainly, also can be with conventional web member with on the permanently fixedly connected desk of pedestal [100] [Z].Such as, utilize bent plate with holes, screw that the rear portion of pedestal [100] and the back of desk [Z] are fixed together.
This embodiment simple structure, volume is little, and part is few, and is in light weight, make easily, than the material consumption much less of general computer desk, also easier assembling, so cost is lower.As long as this device is placed on the common desk, just make this desk become the computer operation table that meets the ergonomics requirement at once, and need not change the structure of desk, also needn't forever be connected with desk, can move easily when needing, recover the table top original appearance of desk.Because Keyboard supporting board can be recovered to when not using above the desk easily, therefore can not seal any drawer of desk, can not take the ground space outside the desk yet.This scheme relatively is fit to the antique traditional furniture of iron wood structure and makes manufacturer's enforcement.
Figure 14 to Figure 19 has introduced second kind of embodiment.The pedestal of this scheme [100] each side has an axle bed [304].Each axle bed [304] is gone up each hinged two fork [302].The lower forearm of tressel [301] is fixedly connected on the back edge of Keyboard supporting board [200], higher postbrachium with about the parallel grafting of two translation guide rods [305].Each is hinged with two forks [302] for each translation guide rod [305].The fork of the same side [302] is also respectively hinged with a translation connecting rod (figure slightly) that prevents the dead angle.
During use, tressel [301] can be driven fork [302] by (referring to Figure 14 to 16) after extracting about 25 centimetres out in the translation guide rod [305] and return turnback (referring to Figure 17 to Figure 19) forward, make Keyboard supporting board [200] drop to the use location.This process of reverse behaviour can be retracted Keyboard supporting board [200] the recovery position of desk [Z] top.
Figure 20 to Figure 24 is the third embodiment.Each hinged fork [302] of the pedestal of this scheme [100] edge, the left and right sides.The lower forearm of a tressel made from the pipe of bending [301] is fixedly connected on the back edge of Keyboard supporting board [200], higher postbrachium and above-mentioned about two forks [302] hinged.
During use, tressel [301] can be driven about 70 degree of fork [302] revolution, make Keyboard supporting board [200] drop to the use location.This process of reverse behaviour can be retracted Keyboard supporting board [200] the recovery position of desk [Z] top.
Figure 25 to Figure 27 is the 4th a kind of embodiment.The structure of this scheme and mode of operation are basic identical with the third scheme, just tressel [301] adopt bending square tube, and different on appearance and modeling.
The advantage of above-mentioned the third and the 4th kind of scheme is that structure is simpler, and shortcoming is that Keyboard supporting board can tilt in moving process.Therefore need locate keyboard, perhaps keyboard and Keyboard supporting board are combined as a whole.
Figure 28 to Figure 31 is the 5th a kind of embodiment.This scheme is similar to first kind of scheme.Except the outward appearance difference, its structural difference is that fork [302] both sides direct and pedestal [100] are hinged, and the translation connecting rod that plays the effect of anti-dead angle is hidden into pedestal [100] inside.In addition, there is casing in the place ahead of pedestal, and has drawer.When Keyboard supporting board [200] when being positioned at the use location, the platform [101] (seeing Figure 31) of a band drawer appears in the front portion of pedestal.After Keyboard supporting board [200] was regained, the platform [101] of band drawer was covered (seeing Figure 28) by Keyboard supporting board [200].
This scheme relatively is fit to the production method based on plastics.
Figure 32 to Figure 34 is the 6th a kind of embodiment.The both sides of the pedestal of this scheme [100] and the postbrachium with the tressel [301] of tubing making are hinged.Keyboard supporting board combines with keyboard, forms integrated keyboard supporting plate [200J].The back edge of the forearm of tressel [301] and integrated keyboard supporting plate [200J] is hinged, and, flexible locating device in its hinge, the angle that makes integrated keyboard supporting plate [200J] and tressel [301] forearm are that 90 degree and 0 are in the steady status that can bear certain torsion when spending.After surpassing certain limit, to surrender the torsion that is subjected to and revolution relatively.Like this, when the integrated keyboard supporting plate [200J] that is in user mode when being subjected to excessive pressure, it can be surrendered and flexibly revolution downwards, and restores when pressure reduces, and plays overload protective function.The tressel [301] that is in user mode can related integrated keyboard supporting plate [200J] together make progress back to be turn 90 degrees, and the dependence gag lever post [3011] of arm roots and the acting in conjunction of axial region spring [T] afterwards is in steady state (SS).At this moment, integrated keyboard supporting plate [200J] is positioned at the top of display [X].In order to strengthen security, the rear portion of pedestal [100] firmly can be connected by the rear portion of gusset [102] with desk [Z].
This scenario-frame is simple, the reliability height, and cost is low.And when the integrated keyboard supporting plate was in the recovery state, the desktop in the place ahead of display can be available.
Figure 35 to Figure 40 is the 7th a kind of embodiment.Respectively there is a guide pipe [306] both sides, the pedestal of this scheme [100] top, insert a crank-like tressel [301] in each guide pipe [306].The same end of two crank-like tressels [301] that are parallel to each other and the lower hinge of Keyboard supporting board [200].
During use, extract tressel [301] out about 25 centimetres by guide pipe [306] is interior earlier, just the width (referring to Figure 35 to Figure 37) of Keyboard supporting board [200] to turning down 90 degree, makes Keyboard supporting board [200] move to use location (referring to Figure 38 to Figure 40) then.This process of reverse behaviour can be retracted Keyboard supporting board [200] the recovery position of desk [Z] top.
Figure 41 to Figure 45 is the 8th a kind of embodiment.This scheme and the 7th kind of scheme are basic identical, and just the fork [3012] at crank-like tressel [301] middle part partly is to be made of two connecting rods that join mutually.
