Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.

As shown in Figures 1 to 6, the mouse apparatus that illustrated a kind of inclined side is held comprises the afterbody 20 that a head 10 and with unsymmetric structure has certain curvature.

Wherein, head 10 comprises the inside surface 11 with thumb contact, cover the front surface 12 of button, the rear surface 14 of moving normally smooth work bottom surface in the horizontal plane and being connected with afterbody, at the extreme higher position of head and top 15 place, inside surface 11, front surface 12, rear surface 14 is connected, top 15 is apart from the span 5 ~ 9cm of work floor height, the first spine 41 is extended forward downwards from top 15, outwards (namely in Fig. 2 to the right) extend the second spine 44 downwards, inwardly (namely in Fig. 2 left) extend the 3rd spine 46 downwards, wherein the second spine 44 and the 3rd spine 46 conllinear are arranged, 3rd spine 46 and the first spine 41 angle between the bottom surface that works projects is 50 ~ 90 degree, the second general spine 44 and the 3rd spine 46 project in the bottom surface that works and preferably avoid vertical setting.

First spine 41 extends to and is about 5 ~ 9cm relative to rear surface 14 most distal point 16 and rear surface 14 distance, preferably get with top 15 to the close value of the height of the bottom surface that works, the difference of the two distance is not more than 3cm and arranges, end points 16 is highly positioned at relative to top 15 highly about 1/2 place or slightly on the upper side, end points 16 and top 15 line are about 50 ~ 80 degree at the angle of the projection on bottom surface relative to base, rear surface 14 that work, 90 degree are transitted to relative to work bottom surface from 0-30 degree from spine 41 part of top 15 to end points 16, preferably, spine 41 comparatively many parts relative to work about 25 ~ 45 degree, bottom surface, namely the first spine 41 from the angle of the part of top 15 to end points 16 at least half length and work bottom surface within the scope of 25 ~ 45 degree.Spine 41 part of end points less than 16 is about 65 ~ 90 degree relative to work bottom surface.Spine 41 extends to the intersection point on top, work bottom surface and end points 16 line coincides with top 15 with end points 16 line in the projection on bottom surface that works in the projection on bottom surface that works.Second spine 44 is relative to rear surface 14 and work bottom surface intersection about 60 ~ 80 degree, identical with the degree of tilt at front surface 12 minimum grade place.3rd spine 46 and the second spine 44 are symmetrical about crossing top 15 vertical line on rear surface 14.Second spine 44 preferably links up smoothly from the part be not less than near position to the top 15 on top 15 with afterbody front end.When device is held in hand side, the part contact more than position on the general and close top 15 of part forefinger proximal joint, likely contact with top 15, near middle finger middle joint, position generally contacts with in the middle of the second spine 44 or middle and upper part.

First spine 41 and the second spine 44 extend to form front surface 12 in opposite directions, and front surface 12 is flat smooth cambered surface, and itself and rear surface 14 are linking up smoothly with the second place of spine 44, and front surface 12 is relative to about 60 ~ 80 degree, the pitch angle at the minimum grade place of work bottom surface.The pulley 53 front surface 12 being provided with the first operating key 51, second operating key 52 and being positioned at therebetween.First operating key 51 is closer to the first spine 41 on front surface 12, and the first operating key 51 all overlaps with the first spine 41 with the outward flange of the second operating key 52 and arranges.

The outward flange reference position of the first operating key 51 is positioned on end points 16, the outward flange final position of the first operating key 51 is not arranged higher than the height of end points 16 apart from work bottom surface, second projection of operating key 52 outward flange on rear surface 14 is parallel with rear surface 14 lower edge, and the second operating key 52 lower edge relative to work bottom surface not higher than about 0 ~ 2cm.The outward flange of the first operating key 51 is along spine 41 obliquely to device (i.e. end points 16) or contiguous position foremost foremost, and the key surface of the first operating key 51 is larger angle with the bottom surface that works but not exclusively vertical.Second operating key 52 is closer to the position of work bottom surface on front surface 12, and more anterior by key surface in the second operating key 52, it is larger that the second operating key 52 inwardly reclaims amplitude compared with the vertical same position of the first operating key 51.Between the first operating key 51 and the second operating key 52, have pulley 53, pulley 53 rotates in housing, and rotation direction is roughly the same with middle finger arthrogryposis direction with forefinger.Pulley 53 is about 20 ~ 45 degree relative to work inclined bottom surface angle.Pulley 53 peak is positioned at top 16 relative to the second spine 44 apart from about half, pulley 53 peak to be less than in the second spine 44 with pulley 53 level point relative to the distance of the vertical plane of the work bottom surface crossing spine 41 relative to the distance of vertical plane of the work bottom surface crossing the first spine 41 close at least not obvious, the second operating key 52 leading edge peak close to but had better not higher than pulley 53 minimum point.

When device is held in hand nature side, forefinger is stopped or is controlled the first operating key 51 place, middle finger is stopped or is controlled the second operating key 52, the front surface 12 comprising two operating keys is conducive to the natural torsion of forefinger and middle finger owing to having appropriate curvature, avoid keeping stiff state, front surface 12 has suitable degree of tilt relative to work bottom surface can make forearm and wrist be in the state loosened.Usual forefinger and middle finger contact with the front portion of the first operating key 51 and the second operating key 52 or middle front part respectively, operation push-button should be finger distal joint to the part between finger tip instead of finger tip firmly, better power can be distributed to whole hand like this.The direction of finger key should be backward, closer to support direction instead of the bending direction of thumb joint, can reduce thumb exerting oneself to four finger directions like this.

First 41 and the 3rd spine 46 extend to form smooth inside surface 11 in opposite directions, inside surface 11 and front surface 12 link up smoothly in the first spine 41, link up smoothly in the 3rd place of spine 46 with rear surface 14, larger than pitch angle, front surface 12 minimum grade place 0 ~ 20 degree of minimum grade place on inside surface 11, and inside surface 11 is not preferably arranged with work plane perpendicular.Inside surface 11 and front surface 12 have the similar preferably larger gradient, and usual thumb distal tip is more to be contacted with 43 places on inside surface 11, should be the state of comparatively stretching when thumb 43 contacts, and the steeper domatic thumb that can make supports with less masterpiece.And the region 43 that contacts with thumb of inside surface 11 has the texture preventing finger sliding, it is contour that center, region 43 is in same pulley peak, relative to rear surface 14 with pulley peak relative to rear surface 14 apart from identical position.

As shown in Figure 1, the base 23 that afterbody 20 comprises arc column structure grip part 22 and is connected with the smooth transition in grip part 22, grip part comprises the front end face 21, upper surface 71 and the lower surface 72 that are flexibly connected with rear surface.

The xsect of afterbody 20 is roughly a fillet quadrilateral, therefore upper surface 71 is smooth surface, and curvature and the arc between front end face 21 center and base 23 center of upper surface 71 connect the identical setting of curvature of a curve to support the palm holding the person of putting.Specifically, upper surface 71 bottom and work bottom surface institute angularly maximum are not less than 60 ~ 80 degree, the line of the horizontal section at male part 81 upper limb place and upper surface 71 intersection mid point and base 23 trailing edge mid point is about 40 ~ 70 degree relative to the bottom surface that works, the inner and outer of upper surface 71 at least at male part 81 upper limb with lower part and work plane perpendicular, be arranged so that upper surface 71 has the cambered outwards radian that adapts with facies palmaris flexibility to support palm like this, hand is better distributed to whole hand to the pressure of afterbody 20, wherein top, grip part mainly provides holding power upwards, middle part and bottom mainly provide the holding power of side direction.When device is held in palm nature side; forearm, wrist and palm are not completely vertical with work bottom surface; palm thenar region lets droop; the supporting role of grip part 22 upper surface 71 pairs of palms makes forearm, wrist and hand be in a comfortable angle of inclination; and make to depart from work bottom surface below thenar region and wrist, avoid these sensitizing ranges oppressed.

Lower surface 72 sets gradually male part 81, transition face 82 and inner fovea part 83 from front end face toward the direction of base 23, the length 2 ~ 5cm of male part curvature maximum portion place xsect.The maximum portion of male part curvature 84 apart from the distance of work bottom surface by the relatively height of work bottom surface, transition face 82 decision such as the work minimum cant of bottom surface and the length of male part curvature maximum portion 84 place xsect etc. relatively of the given maximum portion of inner fovea part curvature 85, relatively the work maximum tilt angle of bottom surface of curved surface between the maximum portion of male part 81 curvature 84 to male part 81 upper limb is not less than 65 ~ 85 degree, in the present embodiment, the maximum portion 84 of male part 81 curvature relative to upper surface 71 apart from being 3cm.Curved surface between the maximum portion of male part curvature 84 to inner fovea part 83 is transition face 82, the minimum cant of transition face 82 relative work bottom surface is not more than 15 ~ 35 degree, the height of relative work bottom surface, the maximum portion 85 of inner fovea part 83 curvature is not more than 2cm, the maximum portion 85 of inner fovea part 83 curvature is 1 ~ 3cmcm relative to upper surface 71 distance, and the maximum portion 85 of inner fovea part 83 curvature is about 0.5-2cm cm relative to the base 23 leading edge degree of depth.

The part of the metacarpal bone of the usual third finger and little finger of toe-between finger joint style and proximal joint rests on the outside of upper surface 71, but nameless angle of bend is little sometimes, the third finger may not contact with the outside of upper surface 71, inner fovea part 83 is formed in the lower surface indent near base portion, lower surface 72 is from inner fovea part 83 from the bottom to top successively in formation transition face 82 and male part 81, the maximum position of curvature of male part 81 is 84, when mouse is held in hand side nameless proximal joint and part in addition may with 84 or location contacts slightly on the lower side, particularly when lifting device, but also likely nameless angle of bend does not quite contact with 84.Because little finger of toe length is shorter; position more rearward; and streblomicrodactyly degree is maximum during natural torsion; therefore usually to contact and around inner fovea part 83; little finger of toe proximal joint and in addition part generally can contact with the maximum position 85 of depressed part intrinsic curvature; little finger of toe proximal joint and the in addition upside of part are generally resisted against and extend on the transition face 82 of 83 by 81; transition face 82 comparatively on grip part 22 other parts be more parallel to work bottom surface; and grip part lower surface above in the of 81 compared with the upper surface 71 of co-altitude grip part 22 more perpendicular to work bottom surface, make 81 places comparatively protrude like this.Grip part 22 diameter at 81 places is large compared with grip part 22 other parts, make nameless around too adduction unlikely during grip part 22, the existence in the space between grip part 22 and head 10 rear surface 14 makes nameless and little finger of toe can natural torsion, nameless and little finger of toe far-end points to inner side instead of points to front, avoids the third finger and little finger of toe to be in abduction state for a long time.Usual little finger of toe has just touched and maybe can not touch close depressed part maximum position portion 85 inside upper surface 71, and little finger of toe can be avoided like this to be in Overadduction state.Grip part 22 lower surface 72 has the texture preventing finger sliding.
