Now, see Fig. 1 earlier, illustrate a kind of writing implement referring to accompanying drawing, represent with reference number 10, this instrument comprises the tubular pen cap 12 in front portion, and has one to be slidably mounted in it, and that moves between ejected position and retracted position writes pen core 14.A cap for brush assembly, reference number is 16, and is described in more detail below, cap for brush assembly tightens to the rear end of the tubulose pen cap 12.Writing assembly 14 is the standard component of pen core or band ink storage device 18 preferably, links to each other with the decrement ink supply pipe 20 that has garden pearl pencil 22.Write part 14 and pull to retracted position by retraction spring 24, spring 24 and the 20 concentric installations of decrement ink supply pipe, and lean against on the joint shoulder 26 by 20 of the end of holder 18 and decrement ink supply pipes.Pen core 14 is equipped with one and is fixed on its rear end, the most handy rolling or garden cylindricality ratchet or cam body 28 that process for stamping is fixing.
Cap for brush assembly 16 comprises that an outer surface is equipped with the tubular rear portion pen cap 30 of pen card 32, as clear expression in Fig. 1 and Fig. 2, the pen cap 30 has a circular open 34 backward, and it holds and supports a depressible actuator button 36 of doing axially-movable in the pen cap 16.Interior shoulder 38 in the pen cap 30 of back, adjacent with opening 34, match in actuator button 36 lip-deep annular edge 40 with one, wear off to prevent button 36, and it is remained in the pen cap assembly 16.At its front end adjacent with ring edge 40, button 36 is made of the collar 42 of an integral body.
In the front portion of actuator button 36, pen cap assembly 16 comprises a common tubular rod core 44, and it has its size can hold the endoporus of the collar 42 of actuator button 36.An annular lip 46 that constitutes in the rear end of bar core 44, actuator button is in the outside of the back pen cap 30.Radially relative finger on the bar core will be sold 52 and 54 and extend forward on the bar core, be respectively to follow face 56,57 towards the cam that tilts at its leading section, and its effect will describe in detail below.
As in Fig. 3 and Fig. 4, clearlying show, the extention of cap for brush assembly 16 is ratchet stop-motion seats 58, pawl seat 58 is clamped in the pen cap 30 of back, and the most handy ultrasonic bonding is fixedly mounted on the cap for brush assembly 16.From centre bore 60 to ratchet stop-motion seat 58.The column ratchet of a pen core 14 or the guider of cam 28a are provided, and cam 28a turns and is slidably mounted in the stop-motion seat 58 like this.It is 62 internal thread that the front end of pawl seat 58 is attacked reference number, external screw thread 64 on the rear end of internal thread and tubular penholder 12 matches, with this as connecting and separately two pens cap 12 and 30 method easily.Therefore, writing implement can be used to take apart so that lay down and change printing ink pencil lead 14.Two radially relative stopping elements 66 and 68 stretch into the centre bores 60 of ratchet stop-motion seat 58 and extend longitudinally therein. Retainer 66 and 68 one of them held by the groove on the bar core 44 70 and 72 respectively.Make bar core finger-like pin 52 with 54 in the ratchet stop-motion seat can with respect to stopping element 66 with 68 with near with the parallel longitudinal sliding motion that concerns. Stopping element 66 and 68 front end are cam respectively and follow face 66a and 68a.Face forward with finger- like pin 52 and 54 corresponding cams follow face 56 and 57 pressed the button 36 o'clock and pen core 14 on ratchet 28 be meshed and ratchet 28 rotated.
Garden cylindricality ratchet or cam body 28a contain a plurality of cam surface 76a to 87a, and they are around central shaft 83 configurations.Cam surface 76a to 87a can with the finger-like pin 52 of bar core and 54 engagements, also can be with the stopping element 66 of ratchet stop- motion seat 58 and 68 engagements so that when button 36 is unclamped by the user, pen core is stopped the rotation.
When press push button 36 and bar core, when pen core 14 rotated with respect to the tubulose pen cap 12 and the cap for brush 16, the axle 83 of cam 28a made between bar core 44 and the cam retainer shaft to aiming at fully.
Known pencil lead pen core or the cam surface of cam 28 76 to 87 very clearly shown in Fig. 5-12 axially and location radially, particularly at Fig. 5, in 6 and 10.As clearlying show among Fig. 5, when pen core in pen fully during retracted position, stopping element 66 and 68 can not utilize the entire depth of deep trouth to locate, deep trouth by the back along 79, bottom surface 86, forward position 81 or back are along 85, and bottom surface 86 and forward position 87 are determined.Use the known ratchet or the profile of cam, can not realize more retraction because in retraction, deep trouth back along face 79 and 85 by last on the ratchet 66,68 of the stopping elements of moving seat 58 end to rotate.End to vertically move by last finger- like pin 52,54, thereby ratchet stops when the pencil indentation penholder 1mm place of pen core.
As the reason sample that is clearly illustrated that among Fig. 6 and Figure 10, in known early stage ratchet mechanism, each cam surface 76,82 (finger- like pins 52,54 must slide above these surfaces, stopping element 66 like this, 68 just can locate in dark retraction groove) all be 45 ° of garden circumferential portion of ratchet or cam body, cam surface 78,84 (during ejecting, finger- like pin 52,54 stopping elements 66,68 slide thereon) be four fens garden circumferential portion of 90 ° or ratchet 28.Two deep trouths (respectively by the back along 79, bottom cam surface 80, forward position 81 and back are along 85, bottom cam is followed face 86, forward position 87 is determined) respectively account for 45 ° of ratchet garden week.Cam surface 82,84 and 86 accounts for half garden (180 °) of ratchet wheel body 28. Cam surface 76,78,80 occupy other 180 ° of its garden week altogether.
In the ratchet or cam 28 of previous technology, ratchet surface 76,78,82 and 84 and the angle of horizontal plane approximately be 28.5 °, cam surface 80 and 86 is levels.
In first preferred embodiment of the present invention, Figure 13 to 20 clearly shows the garden circumferential portion of ratchet 28 very much, and cam 76a to 87a is different with previous technology.
As clearly illustrating that very much in Figure 14 and 18, each cam surface 76a, 82a are placed in the same radial position on the ratchet, but only cover 35 ° of garden circumferential portion, rather than 45 °.Cam surface 78a, 84a also is made into than the cam surface in the early stage technology 78,84 is much smaller, and each only covers 65 ° of ratchet 28a garden week, rather than in the early stage technology 90 °, deep trouth cam surface 80a, 86a be expansion greatly also, respectively account for 80 ° of ratchet garden week, rather than 45 °.
As Figure 21 to 28 very clearly represented, the second embodiment of the present invention had also adopted different shapes to the cam surface of ratchet 28b.In this embodiment, the angle of cam 76b and 82b is similar to the ratchet of early stage technology, keeps 28.5 ° of angles with horizontal plane, and cam surface 80b is also the same with early stage technology with 86b to be level.Cam surface 78b becomes incidence angle with 84b with horizontal plane be 20.56 °.As the clearly expression of Figure 21 institute, when pawl seat retainer 66,68 is respectively placed on 79b, 80b, 81b and 85b, 86b, in the time of in the determined deep trouth of 87b, the entire depth of these grooves is all utilized by stopping element, therefore, make the amount of contraction of pen core in pen increase about 1.0mm, deep trouth has been deepened about 1.27mm than early stage technology, new groove depth 9.271mm.The decline of cam surface 78b and 84b front end is also for during bouncing back, owing to finger-like pin 52 and the 54 darker ratchet 28b that place provide bigger amount of recovery.
As the very clear expression of Figure 22 and 26, cam surface 76b, each of 82b has all covered 70 ° of garden round angles of ratchet 28b, and cam surface 78b is also arbitrary among the 84b
Covered 65 ° of garden round angles, cam surface 80b, 86b has covered 45.
Advantage of the present invention can be by Fig. 5 stretching to the early stage technology of Figure 12 explanation---draws in the operation relatively of second preferred embodiment that the operation of compression apparatus and Figure 13 represent to represented first preferred embodiment of Figure 20 and Figure 21 to Figure 28.
In the retraction mechanism of previous similar means, extremely shown in Figure 12 as Fig. 5, for example two of ratchet 28 deep trouths 67,69 (is the end with cam surface 80,86) hold retainer 66 and 68 respectively, but only partly hold, make cam follow surperficial 66a and 68a when retracted position, be not meshed with the cam bottom surface.Because finger- like pin 52,54 respectively and tiltedly cam face 78 and 84 cooperates, retainer 66 and 68 leans against on descending profile 79 and 85, does not also arrive the bottom of deep trouth.During writing part and being stretched over extended position, as Fig. 6 and shown in Figure 10, finger- like pin 52 and 54 stretches, so that retainer 66 and 68 breaks away from the descending profile 79 and 85 of deep trouth, finger- like pin 52,54 moves and is meshed with the side 77 and 83 of ratchet wheel body 28 along cam face 78 and 84 respectively.When release button 36.Finger- like pin 52 and 54 withdrawals, retainer 66 and 68 meshes with side 77,83, as Fig. 7 and shown in Figure 11, has represented to stretch---the abundant ejected position of the mechanism of contracting.At last, during withdrawing.Shown in Fig. 8 and 12, finger- like pin 52 and 54 and cam face 76 and 82 the engagement, ratchet wheel body 28 moves, make side 77 and 83 break away from retainer 66 and 68 respectively, because spring bias voltage (as shown in Figure 1) causes ratchet wheel body 28 to move on to the retracted mode of Fig. 5 and Fig. 9 once more rotationally.
Stretching of the writing implement that first embodiment of the invention adopted---the operation of the mechanism of contracting is clear that in the expansion view of Figure 13 to Figure 20 very much.For example, Figure 13 and Figure 17 illustrated when pen core 14 is positioned at the position that is withdrawn into writing implement 10 inside, garden cylindricality ratchet wheel body 28a, finger- like pin 52 and 54, stopping element 66 and 68 position.In this position, the deep trouth 67,69 of ratchet 28 is (respectively by surperficial 79a, 80a, 81a and 85a, 86,87a determines) hold stopping element 66 and 68 respectively, so that their cam follows face 66a and 68a is meshed with cam bottom surface 80a, 86a.Because the biasing force of 24 pairs of pen cores 14 of withdrawal spring, pen core 14 remains on retracted position.The finger- like pin 52 and 54 of the bar heart 44 lays respectively at the position that is meshed with cam face 78a and the 84a of ratchet wheel body 28a.Because the gradient of bottom surface 80a, 86a.When contacting with 68a with surperficial 66a, the side 79a and the 85a of deep trouth is rotated respectively and leans on mutually with the stopping element of fixing 66 and 68.
During pen core 14 protracts, as Figure 14 and 18 clear expressions, press actuator button 36, the finger- like pin 52 and 54 of the bar heart reaches the terminal 66a and the 68a of cam surface 78a and 84a arrival stopping element 66 and 68 forward, and the gradient of cam face 78a and 84a makes ratchet wheel body 28 move while rotating with respect to finger-like pin 52 and 54.Displacement movement is subjected to side 79a to be abutted against restriction with 85a mutually with finger-like pin 52 and 54.Be elongation actuator button 36 and 52,54 withdrawals of finger-like pin of finishing pen core 14, simultaneously, ratchet 28a swing offset leans on stopping element 66,68 mutually to decline face 77,83a.Shown in Figure 15 and 19, when this position, the garden pearl pencil 22 of pen core 14 stretches out from the anterior cylindricality pen cap 12, and writing implement 10 can be write.At last, during withdrawing, as Figure 16 and the clear expression of Figure 20, press actuator button 36 once more, finger- like pin 52 and 54 respectively with cam surface 76a, the 82a engagement, continue extension and then make terminal 66a of stopping element and 68a leave the front end of face 77a and 85a respectively, ratchet wheel body 28a swing offset occupies till the entire depth of deep trouth once more to stopping element 66 and 68 then, and is meshed with cam surface 80a and 86a and finishes and stretch---contract the cycle.
Referring now to Figure 21-28 explanation second embodiment of the present invention,, wherein garden cylindricality ratchet wheel body 28b has the geometry of the ratchet wheel body 28 that is different from first embodiment 28a and previous technology.In second embodiment, 45 ° big 25 ° angles of cam face 76b and the previous technology of 82b occupation ratio, each is 70 °, cam face 78b and 84b reduce to 65 ° from 90 ° of previous technology, face 78b and 84b have been shortened, make each new deep trouth (79b, 480b, 81b, and 85b, 86b 87b) has moved about 25 ° clockwise and has reduced between face 78b and the 79b shoulder between 84b and the 85b.Thereby stopping element 66 and 68 can deeper stretch into deep trouth to obtain bigger retraction.With the cam surface 78 of previous technology and 84 angle
Compare, the cam surface 78b of stretching, extension approximately becomes with horizontal plane with 84b
Angle.Therefore, further reduced between surperficial 78b and the 79b and the shoulder between surperficial 84b and the 85b.Deep trouth and the previous the same 45 degree that keeps on week in the garden of technology, but than previous technology dark 1.27mm.At four working stages shown in Figure 21 to Figure 28 with noted earlier identical.In Figure 21, stopping element 66,68 enters in the deep trouth and (is respectively 79b, 80b, 81b and 85b, 88b, 87b).Thereby these elements lean against respectively on descending profile 79b and the 85b, and discord cam bottom surface 80b, 80b nibble the position mutually, and be similar to previous technology.Yet, be positioned at previous technology correspondence position about 25 ° place clockwise at deep trouth, and the shoulder between deep trouth surface 78b, 79b and 84b, the 86b is lower than under the situation of shoulder (Fig. 5) of previous technology correspondence, and stopping element 66 and 68 can deeper enter than previous technology shown in Figure 5 in the corresponding deep trouth.
Figure 22 and 26 expressions pressed the button second embodiment of the present invention at 36 o'clock.At this moment finger- like pin 52,54 ratchet wheel body 28b shift onto terminal 66a and 68a are broken away from respectively or stride across surperficial 78b, 79b and surperficial 84b, 85b between the required place of shoulder, and contact with cam surface 78b and 84b.When button 36 withdrawal, the relation between stopping element 66,68 and the cam body 28b is shown in Figure 23 and 27, and stopping element 66 leans on surperficial 77b, 83b respectively mutually with 68 leading flank.During the retraction shown in Figure 24 and 28.Depress finger- like pin 52 and 54 once more, 28b pushes away downwards ratchet wheel body, breaks away from respectively at the shoulder that reaches between cam face 76b and the side 77b between cam face 82b and the side 83b up to stopping element 66 and 68.In case disengaging shoulder, the bias voltage of shoulder 26 and 12 springs of shell makes the rotation of ratchet wheel body inhour, the end face 66a, the 68a that make cam surface 75b, 82b aim at stopping element 66,68 move, enter once more in the deep trouth up to these elements, shown in Figure 21 and 25.
Stretching of the previous technology of Fig. 5 to Figure 12---contract machine thing and Figure 13 to Figure 20 and Figure 21 compare to mechanism of the present invention shown in Figure 28, as can be seen, any stretch of the ratchet wheel body 28a improved and 28b---the mechanism of contracting makes the haul distance of written portion 14 increase about 1mm owing to adopting.Main difference between the ratchet wheel body 28 of sour jujube body that these have improved and previous technology is to increase according to stopping element 66,68 degree of depth of deep trouth, what be to change combination 16 fully stretches out the ratchet wheel body 28a between retracted position and the angle of 28b swing offset, is to change the gradient of outer cam surface.In this respect, Figure 13 has illustrated: at retracted position, stopping element 66 leans on side 79a, the 85a of ratchet wheel body 28a mutually with 68, and Figure 15 has illustrated: at extended position, stopping element 66 leans on side 77a and 88a mutually with 68.In operation, the swing offset of ratchet wheel body 28a between above-mentioned two positions of stopping element 66 and 68 be much smaller than 90 °, and just the swing offset between retracted position and extended position is much smaller than two half of rotational angle between extended position mutually.Second embodiment to Figure 21 to Figure 28.Situation also is like this, Figure 21 explanation is on retracted position, stopping element 66,68 leans on mutually with side 79b, 85b, and on abundant extended position, same stopping element 66,68 leans on mutually with side 77b and 83b.Therefore, the swing offset of cam body 28b is too much smaller than 90 °, just much smaller than half of two adjacent extended position rotational angles.In fact, the rotation displacement of cam surface 28a and 28b preferably is limited in 65 ° of orders of magnitude.In other words, the angle value that reaches between stop surface 77b and the 79b between stop surface 77a and the 79a is approximately about 65 °.According to comparing, Fig. 5 stretching to previous technology shown in Figure 12---in the mechanism of contracting, cam body 28 is at cam surface 79,85 and the retracted position that leans on mutually of stopping element 66,68 and extended position that cam surface 77,83 and stopping element lean on mutually between displacement, be approximately that ratchet wheel body 28 turns around 1/4th, or 90 °, it is half of rotational angle between two adjacent extended positions.Half result of rotational angle between substantially less than two adjacent extended positions is the limit rotation of the cam body 28a of first and second embodiment and 28b: make lettering pen core body 12 the previous technical body of stroke ratio want big.This can confirm by the length that relatively is designated as R and P on figure.Wherein, R is the minimum retracted length between pen core 14 and the ratchet wheel frame 58, and P is the maximum extension elongation between pen core 14 and the ratchet wheel frame 58.In previous technology book writing tools, the value that P deducts R is 4.66mm, and to deduct the value of R be 5.6mm to P in first embodiment of the present invention, in second embodiment of the present invention, also is 5.6mm.
