Description

Writing implement with shape-variable

Technical field

The utility model relates to a kind of writing implement, and this writing implement generally includes the main body of elongated and comprises the point of writing such as the ball point in the end of this main body.More particularly, the utility model relates to a kind of like this writing implement, and the shape of this writing implement is because its main body can " be moulded " and variable ergonomicity that allows to make this writing implement consider use and comfortableness and be suitable for user's hand.

Background technology

The traditional writing implement that relates to pen and ball pen has the main body of constant rectilinear form and is positioned at the point of writing on the body shaft.These writing implements are solid shapes, i.e. the original shape that their maintenances are had during fabrication is even they can have deformable region in its body surfaces part, the grip zone that particularly uses the soft and elastic material to process.

Also known some motions to writing implement, particularly ball pen, the main body of this ball pen has crooked end, and this crooked end makes writes position and/or the attitude drift of point with respect to body shaft.Such embodiment is open by patent documentation US5527124, US7001090B2 and WO00/72724A1.

From the property held of writing implement with towards the viewpoint of writing this two aspect of observability in district, such curved shape is intended to improve ergonomicity.Yet this curved shape has many shortcomings.

Therefore, the curved shape that obtain for example " Z " word shape of body end is a difficulty and expensive, thereby this curved shape is unmatched with economic manufacturing process.Particularly, it is very difficult obtaining such bool through casting technology, and the demoulding and discharge stage are a problem most.

And except the linkwork by the exquisiteness shown in the above-mentioned document US 7001090B2 was set, curved shape was changeless, and is to be forced by the manufacturing of pen.But, there are the many angle Selection of main body in user's hand and suggestions of location that relate to pen.

And must consider such fact: the user possibly be dexterous people or left-handed people, and even in for example dexterous people's scope, everyone hand is all intrinsic for everyone institute, particularly because its size.Therefore, hand should be suitable for writing implement, although writing implement has supposition " ergonomicity " crooked end.

In order to correct above-mentioned As-Is, oppositely consider it is wise, that is, consider a kind of writing implement that makes shape particularly in grip zone, can be suitable for user's hand.There have been some motions in this regard.

Therefore, patent documentation DE3805997 and NL9100707 have described such writing implement, and the main body of this writing implement has when initial the use carries out deformation ability, are used for solidifying so that be suitable for user's hand before the shape that keeps being given.For this reason, the main body of writing implement is particularly solidified when for example contacting with air or the material of heat cure is processed.Certainly; This solution allows initial " moulding " of the main body of pen; But the shape that obtains like this keeps immobilizing in the whole service life of pen with a kind of determinate mode subsequently; The possibility that does not have change be not under the situation about being entirely satisfactory in initial given shape perhaps under the situation of having changed the user for example.

Patent documentation FR2703627 has also described a kind of pen that makes main body be suitable for user's hand.Yet the document proposes to implement in advance a kind of " model " that adopts shaping cream, adopts a kind of rigid material through processing or molded this model that duplicates then, and this constitutes a kind of time-consuming, complicated and expensive process, and is therefore little in the industrial aspect advantage.And this model has interior stiff shaft on its whole length, has flexible material around this axle, and this has limited the possibility of shape.At last, as for above-mentioned motion, it is changeless enforcement certainly that this process causes a kind of.

According to a significant especially advantage of the utility model, the thermal deformation operation can for example be used to proofread and correct and think that incomplete previous shape perhaps is used to make writing implement to be suitable for the another one user like desired being repeated.This is to be produced by the physics of institute's suggesting material and engineering properties, and particularly by following true the generation, that is, according to completely reversibility and reproducible phenomenon, it is plastic that these materials become.

According to first embodiment of the utility model, the main body of writing implement is processed by the heat deformable material on the whole.Therefore, can adjust the geometry of the integral body of this main body.In this case, main body can have local the layout, for example forms at least one zone of folding portion, and this at least one zone formation rationally is positioned at the one or more preferential deformed area on the said main body.Therefore, two such districts can be set, these two districts and the less distance of end part interval with the main body of writing point, this allows near this end, to give main body a pair of curved shape.

Can notice, be contained in the ink cartridge of body interior or " natural " pliability of pen core and allow the distortion of this main body and particularly crooked.

According to second embodiment of the utility model, the main part of writing implement ground is by can not heat deformable material processing and partly processed by the heat deformable material.Particularly, the heat deformable material is arranged in the grip zone of writing implement, that is, user's finger applies the place of effect.More particularly, can not heat deformable material be present in the part of the main body that should keep permanent rigidity and very accurate and constant geometry, for example:

Near-the part leading section of main body, this part are carried and are write point, and/or

Near-part rearward end can be equipped with the rear enclosed plug and/or the protective cap of this main body in this one.

According to supplementary features; Can in the heat deformable material of the main body of writing implement, add thermochromic dye; This thermochromic dye has the characteristic that when giving fixed temperature with the softening temperature of said material is corresponding, changes color, for example is about 70 ℃ temperature under the situation of polycaprolactone.The interpolation of this dyestuff offers a kind of simple vision indication of user, for example forwards white to from blueness, reports enough heat and so can " moulding " of writing implement to the user.Otherwise when main body was cooled off, its color was for example got back to blueness from white, and therefore the user is apprised of its writing implement its initial rigidity of new shape recovery just to be given.

Another significant advantage of this writing implement, promptly the purpose of the utility model is the manufacturing simplification of writing implement, permits using the molding technique of current good grasp to realize economic commercial production.Particularly, the main body of this writing implement can be injection moulded to be shaped and be rectilinear form, and this is avoided the demoulding and discharges the hell and high water outside mould.In case discharge and still enough hot; The main body of writing implement just can stand to be out of shape first by the configuration instrument in factory; Also can be referred to as " predeformation "; Final user always can change and make its personalization to the shape that provides in factory through reheating the main body of writing implement.

Can not heat deformable material and the situation of the heat deformable combination of materials main body of getting up under; According to above-mentioned second embodiment that provides; Manufacturing approach can be used through considering the casting of " two material " type; For example comprising adopting the original moulded of each one of can not heat deformable material processing, is molded to duplicating of each one of adopting the material that the heat deformable material processes then.At this, the distortion first of main body can be discharged mould from it and implemented in factory.

Certainly, also can abandon " predeformation " of such main body and pay and sell employing, can keep final initiative for the user in this case distortion for example at the writing implement of the rectilinear form that when mould is discharged, obtains.
