Definitions

  • the present invention relates to a shaft cylinder of a writing tool, and more particularly to a shaft cylinder of a writing tool equipped with a holding aid which enables the writing tool to be gripped even with a weak force.
  • one writing tool is provided with grooves in the part held between the user's fingers (e.g. thumb, index finger and middle finger), or another uses rubber as the material of this part, both with a view to firmer holding. Or a belt of rubber or the like, provided apart from the writing tool proper, is inserted into the grip part to increase the firmness of gripping.
  • every one of these proposed items basically depends on holding only by the thumb, index finger and middle finger for gripping of the writing tool, and therefore the manner of applying the pressure to the writing point is limited to relying on these three fingers.
  • the above-cited holding aid for writing tool involves a problem in the stability of holding the writing tool; especially it embodies no consideration for cases in which writing for a long time is required or in which a user having a trouble or a handicap, if only temporarily, on the arm or fingers, is required to hold the writing tool with a relatively weak gripping force without feeling exhausted, and this means room for improvement.
  • An object of the present invention is to obviate the disadvantages of the conventional art noted above and provide a shaft cylinder of a writing tool equipped with an improved novel holding aid which enables a stable and yet continuous gripped state to be maintained with a relatively small gripping force.
  • a shaft cylinder of a writing tool has an inter-finger contact lever formed in the intermediate part of the shaft cylinder in the lengthwise direction and a grip disposed ahead of the inter-finger contact lever, the shaft cylinder of a writing tool having a holding aid formed by arranging the inter-finger contact lever to be accommodable into the shaft cylinder.
  • the shaft cylinder of a writing tool in the first mode has an aid configured by arranging the inter-finger contact lever movably and immovably relative to the lengthwise direction of the shaft cylinder.
  • the shaft cylinder of a writing tool in the first mode or the second mode has an aid configured by arranging the inter-finger contact lever to be rotatable around a perpendicular orthogonal to the axis of the shaft cylinder in the lengthwise direction.
  • the shaft cylinder of a writing tool has an aid configured by arranging the inter-finger contact lever to be fixable at any desired angle to the axis of the shaft cylinder in the lengthwise direction.
  • the shaft cylinder of a writing tool has an aid in which the angle of the inter-finger contact lever to the axis of the shaft cylinder in the lengthwise direction is between 30 degrees and 90 degrees.
  • the shaft cylinder of a writing tool has a holding aid in which the angle of the inter-finger contact lever and the shaft cylinder (in particular the grip) are arranged to be rotatable relative to the axis in the lengthwise direction. This configuration permits selective changes in the orientation (directionality) of the paper contacting part of the writing tip as desired and changes in the paper contacting position of the writing lead having worn by the use in writing.
  • the shaft cylinder of a writing tool has a holding aid wherein a rotational resistance is provided to the relative rotation of the inter-finger contact lever and the shaft cylinder.
  • the shaft cylinder of a writing tool has an aid in which the rotational resistance is varied according to the writing pressure.
  • the shaft cylinder of a writing tool has a holding aid in which at least one of the grip and the inter-finger contact lever is provided with an anti-slide property.
  • a shaft cylinder of a writing tool wherein an inter-finger contact lever is formed in the intermediate part of the shaft cylinder in the lengthwise direction, a grip is disposed ahead of and closer to the writing tip than the inter-finger contact lever, and the inter-finger contact lever is arranged to be accommodable into the shaft cylinder, the accommodation being accomplished by disposing the inter-finger contact lever to be rotatable around a perpendicular orthogonal to the axis of the shaft cylinder in the lengthwise direction and the shaft cylinder being formed by arranging the inter-finger contact lever to be movable and fixable relative to the lengthwise direction of the shaft cylinder.
  • FIG. 1 A first embodiment of the present invention will be described with reference to Figure 1 through Figure 8 .
  • the upper part in the drawings will be referred to as the rear part in the description, and the lower part, as the front part.

  • a cylindrical fitting 14 is unrotatably disposed on the shaft cylinder 1 though it is movable back and forth relative to the axis of that shaft cylinder 1 in the lengthwise direction.
  • engagement of flat parts 15 formed on opposing sides of the shaft cylinder 1 and flat parts 16 formed on the inner face of the cylindrical fitting 14 with each other makes the cylindrical fitting 14 unable to rotate relative to the shaft cylinder 1.

  • This swell 18a not only can maintain the expanded position in a stable state by bringing the inter-finger contact lever 17 into contact with the slope 18b but also serves as an assisting part when the angle adjusting member 18 is to be manipulated with fingers.
  • the angle adjusting member 18 is arranged backward, and the inter-finger contact part 17b of the inter-finger contact lever 17 and the angle adjusting member 18 are in a relationship of not coming into contact with each other.
  • the inter-finger contact part 17b of the inter-finger contact lever 17 is then brought into contact with the slope 18b of the angle adjusting member 18, and the rotation is stopped to maintain the angle of expansion ⁇ .
  • Figure 4 shows a state in which the inter-finger contact lever 17 is accommodated in the cylindrical fitting 14.
  • the angle adjusting member 18 is arranged ahead to slide on the rail 14b of the cylindrical fitting 14, and is in a relationship in which the inter-finger contact part 17b of the inter-finger contact lever 17 is in contact with the slope 18b of the angle adjusting member 18.
  • the rotation of the inter-finger contact lever 17 then is in a state of being suspended on the way by the angle adjusting member 18, and the angle of expansion relative to the lengthwise direction of the shaft cylinder 1 of the inter-finger contact lever 17 is set and fixed to an angle of expansion ⁇ , greater than the angle of expansion ⁇ of the inter-finger contact lever 17 shown in Figure 1 .
  • FIG. 10 A second case in which the angle of expansion of the inter-finger contact lever relative to the lengthwise direction of the shaft cylinder 1 can be set as desired is shown in Figure 10 and will be described below.

  • the position of fitting the cylindrical fitting 14 (the inter-finger contact lever 17) to the shaft cylinder 1 can be set steplessly.
  • Figures 38 and 39 show a seventh case in which the cylindrical fitting 14 on which the inter-finger contact lever 17 is arranged can move in the lengthwise direction of the shaft cylinder 1.
  • the shaft cylinder 1 is provided with the cylindrical fitting 14 and the inter-finger contact lever 17.
  • a semispherical convex portion 68 is provided, which is urged by the elasticity of resin toward the center of the shaft cylinder 1.
  • Grooves 69 constituting part of a spiral by turning at regular intervals and in an inclined state, are disposed in the outer circumference of the shaft cylinder 1 by repeated alternations of clockwise and counterclockwise directions.
  • the grooves 69 are in the so-called switchback shape.
  • a concave portion 70 deeper than the grooves 69 is provided in each of the positions where the turning direction of the grooves 69 is reversed, namely each turning point of the switchback shape.
  • the convex portion 68 of the cylindrical fitting 14 engages with this concave portion 70 to determine the position of the cylindrical fitting 14.
  • the cylindrical fitting 14 is brought into a fixed state relative to the shaft cylinder 1. This prevents, when the user slides the cylindrical fitting 14 (the inter-finger contact lever 17) to control it, momentum from letting the cylindrical 14 fitting pass and go beyond the preferred position and ensures a reliable sliding movement within a predetermined section without fail, resulting in further improvement in operability and user-friendliness.
  • the angle of expansion of the inter-finger contact lever 17 relative to the lengthwise direction of the shaft cylinder 1 can be set as desired (as shown in Figure 1 and elsewhere).
  • the legs 17a of the inter-finger contact lever 17 are rotatably fitted to the supporting axis 14a of the cylindrical fitting 14 as stated above, and the engaging stubs 19 are provided on part of the peripheries of the legs 17a.
  • a plurality of engaging steps 20 are provided on the cylindrical fitting 14 on a circle coaxial with the supporting axis 14a and are detachably engaged with the engaging stub 19.
  • the engaging stub 19 engages, in a stepwise manner, any one of the plurality of engaging steps 20.
  • This determines, and places in a fixed state, the angle of expansion of the inter-finger contact lever 17 relative to the lengthwise direction of the shaft cylinder 1.
  • the appropriate angle of expansion of the inter-finger contact lever 17 relative to the lengthwise direction of the shaft cylinder 1 is 60 degrees, a similar effect can be achieved in an angle range of 30 to 90 degrees unless the way of holding the writing tool is extremely different.
  • Each monitor in the test was supposed, after setting the position of the inter-finger contact lever 17 for each model, to write five typical Japanese characters five times on a B-size ruled notebook page.
  • the electromyogram and writing pressure of each person were measured.
  • the criteria of subjective evaluation were "writing ease” and "relative freedom from exhaustion", and paired comparison was done on a scale of five grades.
  • the monitoring was done by 15 persons (nine male and six female persons, all right-handed).
  • models were presented at random to avoid the influence of the sequence of model presentation.
  • the measured items were as follows.
  • EMGs electromyograms
  • the third and fourth EMGs of the five rounds of writing five typical Japanese characters with each sample were integrated, and compared by dispersion analysis.
  • a lead feeding mechanism 71 is accommodated within the shaft cylinder 1. Its lead feeding mechanism will be described. Ahead of a lead tank 72 capable of accommodating a plurality of leads, a chuck body 74 which holds and releases a lead is fitted via a coupling member 73; a ring member 75 is pressed into and fixed in the intermediate part of the coupling member 73, and longitudinal ribs 76 are formed in four positions at equal intervals on the outer circumference of the ring member 75.
  • a chuck ring 77 for opening and closing the chuck body 74 surrounds the part ahead of the chuck body 74.
  • Ahead of the chuck body 74 there is arranged a slide member 89 having within it a lead-detent member 78 which is made up of a rubber-like elastic body to prevent the lead from retracting.
  • an eraser 80 is detachably fitted via an eraser receptacle 79.
  • Reference numeral 81 designates a knocking member which covers the eraser 80 and serves to feed out a lead, and the knocking member 81 is detachably fitted to the eraser receptacle 79.
  • An intermediate screw 82 is fitted ahead of the lead feeding mechanism 71 and the lead feeding mechanism 71 is fixed to a front shaft 83 by the intermediate screw 82.
  • the front shaft 83 comprises an intermediate shaft 83a and a tip fitting 83b, and these intermediate shaft 83a and tip fitting 83b are detachably fixed by screwing. Holding of a flange 82a formed on the intermediate screw 82 of the lead feeding mechanism 71 between the intermediate shaft 83a and the tip fitting 83b causes the lead feeding mechanism 71 to be fixed to the front shaft 83.
  • longitudinal ribs 84 are formed on the outer circumferential face of the intermediate screw 82, longitudinal grooves 85 are formed in the inner circumferential face.
  • the longitudinal ribs 84 of the intermediate screw 82 can engage with longitudinal grooves 86 of the intermediate shaft 83a, while the longitudinal ribs 76 of the ring member 75 can engage with the longitudinal grooves 85 of the intermediate screw 82.
  • This arrangement enables, when the grip 37 is rotated relative to the shaft cylinder 1, the rotation to be transmitted to the chuck body 74 securely holding a lead and the unevenly worn lead to be thereby turned without fail.
  • a metal-made tip member 87 is detachably fixed by screwing ahead of the intermediate screw 82.
  • a repulsive member 88 such as a coil spring, is stretched between the intermediate screw 82 and the lead tank 72, and urges backward the lead tank 72 and the chuck body 74.
  • the lead-detent member 78 which is made up of a rubber-like elastic body to prevent the lead from retracting is arranged on the tip member 87
  • the lead-detent member 78 also gives a frictional resistance against the sliding between the tip member 87 and the slide member 89.
  • the frictional resistance of the slide member 89 against the tip member 87 is set greater than the frictional resistance of the lead against the lead-detent member 78.
  • a reduced diameter part 87a is formed on the front inside of the tip member 87, and an enlarged diameter part 87b is formed on the rear inside of the reduced diameter part 87a; while those reduced diameter part 87a and enlarged diameter part 87b are linked and integrally formed, they can as well be configured of separate members and linked together. However, in order to align the central axes of the two parts, it is more desirable to integrate them.
  • both the tip member 87 and the slide member 89 which swings within the tip member 87 are made of a metallic material in this case, they may as well be made of a resin material or of different materials.
  • an O ring 91 made up of elastic rubber intervenes in the screwed part between the intermediate screw 82 and the tip member 87. While the O ring 91 prevents the intermediate screw 82 and the tip member 87 from loosening, the tip member 87 is made detachable from the intermediate screw 82, and this configuration enables them to be intentionally separated from each other and the slide member 89 to be removed. Thud, this arrangement makes repair work possible even in the rare case of a lead getting broken within the tip member 87.
  • Reference numeral 92 designates a transparent resin-made tip member pressed into the front inside of the tip fitting 83b, and behind the tip member 92 slits 92a are formed in two opposing positions. They are slits to facilitate insertion of the tip member 92 into the tip fitting 83b; the tip member 92, in a state in which its rear part is bent in the direction of the inner diameter, is inserted into the tip fitting 83b and, after it is inserted, a pressing-in force stable and free from sagging for a long period, can be achieved though the force somewhat weakens. In the rear inside of the tip member 92, the tip member 87 is positioned in a state of circumferential contact.
  • the central axes of the tip member 92 and of the slide member 78 are aligned. Further, since the tip member 87 is screwed and fixed onto the lead feeding mechanism 71 via the intermediate screw 82 as stated above, it is aligned with the central axis of not only the lead feeding mechanism 71 but also those of the tip member 92 and others.
  • the accurate alignment of the central axes of these lead feeding mechanism 71 (the intermediate screw 82) tip member 92 and slide member 78 enables the lead fed from the chuck body 74 to be guided, without being bent, accurately to the lead-detent member 88 and protrudes from the tip of the slide member 78.
  • the front inside of the tip member 92 constitutes a reduced diameter part 92b, and the rear inside in which the slits 92a are formed constitutes an enlarged diameter part 92c.
  • the external shape of the tip member 87 also has an outer diameter equal to those of the reduced diameter part 92b and enlarged diameter part 92c of the tip member 92.
  • the tip fitting 83b which may be formed of a metallic material, is made up of a resin material in this example, and the surface of the resin is plated to have a plating layer 40, but a paint coat may as well be formed by applying a paint.
  • the tip member 92 is inserted into the tip fitting 83b, resulting in a similar action to the foregoing case.
  • the shaft cylinder 1 comprises the shaft cylinder 1 externally fitted with the cylindrical fitting 14 having the inter-finger contact lever 17 and the front shaft 83 (the intermediate shaft 83a) into which the grip 37 is fitted, and the shaft cylinder 1 and front shaft 83 are linked to be rotatable in the circumferential direction around the axis of the shaft cylinder 1.
  • a flat part 83 is formed on the surface of the shaft cylinder 1, and a flat part formed within the cylindrical fitting 14 is under pressure contact with the flat part 83.
  • This arrangement prevents the cylindrical fitting 14 from turning relative to the shaft cylinder 1.
  • the inner face step 42 is formed within the shaft cylinder 1, while at the rear end of the front shaft 83 (the intermediate shaft 83a) the rear end flange 40a which engages with the inner face step 42 is formed.
  • the engagement of these rear end flange 40a and inner face step 42 provides a rotational frictional resistance to the relative rotation of the shaft cylinder 1 and the front shaft 83 by strengthening their engaging force.
  • the shaft cylinder 1 and the front shaft 83 do not turn relative to each other unless some load is imposed.
  • a repulsive member 93 such as a coil spring, is arranged between the shaft cylinder 1 and the front shaft 83 to urge each other in the lengthwise direction.
  • the repulsive member 93 urges them in the mutually isolating directions, and this urging force also provides a rotational frictional resistance to the relative rotation of the shaft cylinder 1 and the front shaft 83.
  • the repulsive member 93 is positioned within the shaft cylinder 1 for an aesthetic reason.
  • a large-diameter space part 94 is formed inside the front part of the shaft cylinder 1, and the repulsive member 93 is arranged in that large-diameter space part 94.
  • the repulsive member 93 is stretched between an internal step part 94a, formed by disposing the large-diameter space part 94, and an intermediate flange part 95 of the intermediate shaft 83a.
  • the repulsive member 93 may as well be stretched in an exposed state between the front end of the shaft cylinder 1 and the intermediate flange part 95 of the front shaft 83.
  • Flat parts 93a are formed near the two ends of the repulsive member 93.
  • the formation of the flat parts 93a near the two ends is intended to minimize the catching at the contact parts between the angles of the ends of the repulsive member 93 and the shaft cylinder 1 (the front shaft 83). It should be noted that if any catching occurs, the resultant friction may invite generation of powder or even the diameter expansion of the repulsive member (coil spring) 93, involving a risk of failure to achieve relative rotation.
  • metal-made washers 96 are disposed before and behind the repulsive member 93 ( Figure 59 ). The presence of the washers 96 intervening between the repulsive member 93 and shafts serves to further ensure prevention of the otherwise likely catching.
  • a counter-sunk spring 97 may be used in place of the repulsive member 93 made up of a coil spring ( Figure 60 and Figure 61 ). Folded parts 97a are formed at equal intervals on that counter-sunk spring 97.
  • Reference numeral 41 designates a clip configured of a separate member and fitted to the shaft cylinder 1, but this member can as well be integrally molded. As in the foregoing case, the clip 41 is arranged in a position reverse to the inter-finger contact lever 17. It is so positioned as not to obstruct writing.
  • a third example of the turning mechanism will be described with reference to Figure 62 through Figure 66 .
  • a plurality of concave portions 98 formed on the circular edge, which is the front end of the shaft cylinder 1, are formed at equal intervals.
  • stubs 99 to engage with and disengage from the concave portions 98 of the shaft cylinder 1 are formed on the upper face of the intermediate flange part 95 of the front shaft 83 (the intermediate shaft 83a).
  • the stubs 99 are formed in four mutually orthogonal positions, but their positioning is not limited to this.
  • the front shaft 83 of the shaft cylinder 1 is urged by the repulsive member 93 in the mutually isolating directions, and this serves to keep the concave portions 98 and the stubs 99 engaged only shallowly at normal times (see Figure 63 ).
  • the shaft cylinder 1 and the front shaft 83 are enabled to be turned relative to each other by a relatively weak force.
  • the shaft cylinder 1 advances against the elastic force of the repulsive member 93, and this deepens the engagement between the concave portions 98 and the stubs 99.
  • An elastically deformable guide cylinder may as well be used in place of the tip member 92. Specific examples of this configuration will be described with reference to Figure 67 and Figure 68 .
  • a holding member 100 formed of an elastic body is pressed into and fixed in the inside of the front end of the front shaft 83 (the front shaft part 83a).
  • the holding member 100 is formed here of a rubber material such as urethane rubber, ethylene acryl rubber, epichlorohydrin rubber, acryl rubber, ethylene propylene rubber, chloroprene rubber, natural rubber, isoprene rubber, polyethylene chlorinate, nitrile rubber or silicone rubber, but it may as well be made of an elastomer such as styrene elastomer, olefin elastomer, esteric elastomer, urethane elastomer, elastomer gel or polyethylene gel, of an elastic resin such as acryl resin, fluorine resin, vinyl chloride or polyethylene resin.
  • a rubber material such as urethane rubber, ethylene acryl rubber, epichlorohydrin rubber, acryl rubber, ethylene propylene rubber, chloroprene rubber, natural rubber, isoprene rubber, polyethylene chlorinate, nitrile rubber or silicone rubber, but it may as well be made of an elastomer such as
  • the front part of the holding member 100 is conically shaped, tapering forward, and its conical part 101 protrudes from the front end of the front shaft 83.
  • a circular groove 102 is formed in the outer circumference of the intermediate part of the holding member 100, and a circular protrusion 103 formed on the inner circumferential face of the front shaft part 83a is fitted into that circular groove 102.
  • the fitting of the circular protrusion 103 into the circular groove 102 causes the holding member 100 to be fixed to the front shaft 83 and prevents it from coming off.
  • a smaller diameter part 104 and a larger diameter part 105 are formed in that order from front to back, and those smaller diameter part 104 and a larger diameter part 105 are formed by a conical part 106 in linkage.
  • the bore of the smaller diameter part 104 is slightly smaller than the outer diameter of the tip 13 of the ballpoint pen ink reservoir 2 to be used, while the bore of the larger diameter part 105 is slightly smaller than the outer diameter of the tip member 87 of the mechanical pencil unit.
  • Behind that larger diameter part 105 there is formed a conical part 107 expanding backward to facilitate assembly when a ballpoint pen or a mechanical pencil unit is to be inserted.
  • the smaller diameter part 104 is in a position exposed from the front shaft part 83a, while the larger diameter part 105 is positioned inside the front shaft part 83a.
  • the lead feeding mechanism 71 of a mechanical pencil is arranged as in the foregoing example, but the mechanical pencil can as well be made retractable into the shaft cylinder 1 by using a davit cam system.
  • the outer diameter part 108 of the tip member 87 is in contact in a state of being somewhat pressed into the larger diameter part 105 of the holding member 100.
  • the outer circumference of the larger diameter part 105 is prevented by the inner face of the front shaft part 83a from being deformed.
  • the larger diameter part 105 is kept in contact with and held by the tip member 87 of the mechanical pencil in this example, the vicinities of the front end of the tip member 87 may as well be kept in contact with and held by the smaller diameter part 104. If held by the smaller diameter part 104, it results in the exposure of the outer circumferential part of the smaller diameter part 104, and a relatively large elastic deformation can be achieved, resulting in a sense of soft writing like what is felt in writing with a brush.
  • the material of the holding member 100 is similar to that in the foregoing case, but it is preferable to set the hardness to between 50 and 80 degrees in Shore A count, and a range of 5 to 80 degrees would give a substantially similar effect. However, at 50 degrees or less, some user may find the quantity of deformation in the writing part extremely great when he or she writes, and feel more or less awkward. While the foregoing description assumed a true circular shape for the smaller diameter part 104 and the larger diameter part 105, where they are not circular, they should be understood as being a small size part and a large size part, shaped small and large respectively.
  • Figure 69 shows a case in which a ballpoint pen ink reservoir 2 containing water-soluble ink or oil-soluble ink is arranged in the shaft cylinder 1.
  • the ballpoint pen ink reservoir 2 comprises an ink tank 109 and a ballpoint pen tip 13 pressed into and fixed to a part ahead of the ink tank 109. At the tip of that ballpoint pen tip 13, a ball 110 to serve as the writing point is fitted rotatably.
  • the ballpoint pen ink reservoir 2 is urged by a repulsive member 111, such as a coil spring, toward the back, namely in the direction of being accommodated into the shaft cylinder 1.
  • Reference symbol 112 designates a passive member which regulates the forward movement of the repulsive member 111, and is pressed into and fixed to the inside of the shaft cylinder 1 behind the holding member 100.
  • Reference symbol 113 designates a protrusion formed in the intermediate part of the ballpoint pen ink reservoir 2, where one end of the repulsive member 111 is formed. Behind this shaft cylinder 1, a davit cam or some other retracting mechanism (not shown) for moving forward and backward the ballpoint pen ink reservoir 2 is arranged to make it possible to maintain the protruding state of the ballpoint pen ink reservoir 2.
  • the ballpoint pen tip 13 of the ballpoint pen ink reservoir 2 is kept in contact with and held by the smaller diameter part 104 of the holding member 100 in a somewhat pressed-in state.
  • the smaller diameter part 104 is exposed from the front shaft part 83a and, as the deformation of its surface is not restricted, can be deformed with relative freedom.
  • the ballpoint pen tip 13 can flexibly move in the circular direction though remaining held by the holding member 100, giving the user a sense of flexible writing like what is felt in writing with a brush.
  • the conical part 106 or 107 of the holding member 100 serves as a guide to ensure smooth retracting/extruding actions.
  • the foregoing description referred to a case in which the holding member 100 is exposed from the tip of the front shaft part 83a, the exposed holding member 100 would serve as a damping member should the writing tool happen to be dropped from the desk or elsewhere.
  • the elastic deformation of the holding member 100 damps the impact to which the writing tool itself would be subject.
  • the holding member 100 would directly clash against the floor or the like, resulting in a tremendous damping effect.
  • the shaft cylinder of a writing tool provided with a holding aid according to the invention is characterized in that it has an inter-finger contact lever formed in the intermediate part of the shaft cylinder in the lengthwise direction, a grip disposed ahead of the inter-finger contact lever, and the inter-finger contact lever to be accommodable into the shaft cylinder; this configuration permits stable support of the writing tool without being affected by the way in which the user grips it or by his or her gripping force, making it possible to achieve a sufficient writing load with a relatively small gripping force and superiority in portability and handling ease.
