Existing writing-painting is straight-bar, is made up of a body (bar), nib, pen cap members such as (caps).The applicant investigates repeatedly in ten Yu Jia megastore for many years, does not find to have in the existing system pen technology pen of knee.In " pen a family " (light industry publishing house), " (children learn calligraphy " (Mapping Press) with the kind of pen.

The purpose of the anti-nearly pen of knee.The penholder bending allows nib remain at finger the place ahead, can not lived the sight line of oneself by stick shift, meets correct pen holding posture requirement, has enlarged the visual field when writing, and helps keeping health honest, forms correct writing style, prevents the generation of backbone deflection and myopia.

The purpose of this utility model is achieved in that does the crooked transformation of a S shape with the penholder part of conventional straight post pen below the place that holds a pen, make the about 5mm of nib reach, be the place ahead that the axis of written portion is in axis, penholder top, its extended line becomes 5 ° to 10 ° angle.Hold a pen the position in the back crook of S shape knee, and its lower edge is to the about 3.3cm of writing paper vertical range, the rounded or triangle in cross section, position that holds a pen, and appearance is recessed slightly " thumb pad ", increases comfort.Knee also can by about vertical profile two synthetic, middlely form curved groove, embed for pen core or barrel.Curved groove inner wall surface can be provided with reticulate pattern or liner, makes the pen core barrel fastening.About two coincide after, screwing assembling with the screw thread at two ends and nib and penholder top again can use.

Existing straight-bar pen allows first children with pen form incorrect pen holding posture and writing style easily, and the children that formed wrong pen holding posture then are difficult to correct bad habit.Children's finger muscles is tender, and strength is small and weak, grips very low because of writing effort easily when holding a pen, then covered sight line by hand, have to slanting head closer, cause the twisting of crookback anticline shoulder, greatly injure child's eyesight, also jeopardized the physiological bending and the normal development of backbone.In actual life, in video display, photographic work, often can see the incorrect writing posture of teenager, troubling.Fault has been acknowledged as the one of the main reasons of bringing out children and adolescents myopia and spinal curvature.The product of the pre-myopia preventions of posture correction such as anti-nearly reading stand, anti-close-table lamp, " back of the body back of the body is good ", " heroic bearing band " successively appears in market, but all can't prevent wrong pen holding posture.Propelling pencil fractures easily, grips low torticollis and condescends to take the post easilier, has newspaper to step on to appeal pupil's propelling pencil of stopping using to use the article of Wood pencil instead.The anti-nearly pen of knee compares with original straight-bar pen; the nib reach; moment is very little, and the place of holding determines that it is calm to write; help rectifying pen holding posture; form the good custom of writing, (health is from table one fist, and eyes are from paper one chi for " three " of correct writing posture; finger is from the paper one-inch) material guarantee is provided, play protect young people children ' s vision and healthy good action.

The explanation of accompanying drawing drawing.(1), (2) are the nib and the pen item of nib among Fig. 1 Fig. 2, and (3), (4) are the antecurvature and palintrope of S shape knee, and (5) are penholder top, and (6) are the thumb pad at knee place; Fig. 3 Fig. 4 is the section of knee, and (7) are curved groove, and (8) are antecurvature hole; Fig. 7 is for being inserted with the schematic diagram of short pen core in the antecurvature hole; Fig. 8 and Fig. 9 Figure 10 are the different patterns of pen head part: the schematic diagram of running water nib, writing brush head.

Realize best way of the present utility model, be to utilize an existing various systems part as far as possible, as various nibs, penholder, pen core, adopts cooperation part to save development cost.Main contents of the present utility model are to make the penholder bending, thus reach make nib preposition, broaden one's vision, unimpeded sight line, the purpose that the position that holds a pen is resolved; Only make with moulding, can save die cost and shorten the construction cycle in the knee part.Pen head part can many kinds pattern, except that ball pen head, mound nib, running water nib, also can be equipped with needle-tube pen-point, duckbilled nib, pencil-lead, guided missile lead for retractable pencil.Pen head part comprises a pen that is used for tightening pen core and links with knee, and just like using structure, the pen appearance that can regulate lead for retractable pencil can add reticulate pattern to increase frictional force in the compasses, being convenient to screw and loosening and make the knee driving fit is an integral body.The antecurvature hole of knee becomes the straight trough shape with pen head part UNICOM, can insert refill for ball-point pen (" bowknot " that have the fixed position effect), guided missile lead for retractable pencil from lower to upper through pen head part, and screwing the pen item then can use.This top that also shows pen core can not enter penholder top, thereby provides possibility widely for createing special-shaped knee pen.If the inner existing curved groove of knee has straight trough again, but then dual-purpose is bent straight two kinds of pen cores.Existing refill for ball-point pen is made with plastic straw, and certain plasticity and elasticity are arranged, and bending can be used in the anti-nearly pen of knee a little, and the applicant was once on probation feasible from simulation.Refill for ball-point pen should adopt erasable type, is more suitable for children and uses.The anti-nearly pen of the knee of adapted refill for ball-point pen also can be simplified the knee structure, makes integrally on knee and the penholder, utilizes the plasticity of pen core directly to insert use; And can consider that the disposable knee of overall fixed prevents nearly ball pen.
