Description
9~3~S
The present invention rela-tes to a writing instrument and more particularly, to a writing instrument having manually separable parts of nib and pen holder so that either new nibs or different pen point gauges can be arbitrarily changed.
Conventional writing instrumen-ts, such as cellulose~
nib or ball-nib pens for use in signing have a fixed or all-in-one part of the nib and pen holder because of favorable pro-duction in the assembly line. Therefore, it is impossible to separate nib from pen holder without proper tools or without destruction. Once the nib is broken or worn out, the whole pen must be discarded even if the pen holder is still in a good condition.
Further as the gauge or the fineness of a conventional writing instrument is fixed, several writing instruments must be provided for different purposes, such as for engineering drawing or for signatures.
The present invention provides a writing instrument with a replaceable pen-nib, to enable the full use of pen holder or the other parts which is only necessary to replace the damaged parts.
The present invention also provides writing instrument having a spare pen-nib in the pen holder thereof which is im-mediately replaceable as soon as the operative pen-nib is worn out or damaged, which assures no interruption of writing on important occasions, i.e. dictating letters, attending impor-tant press conferences or in examinations.
The present invention further provides a writing instrument with a series of spare pen-nibs of different gauges present in its pen holder for different requirements on dif-ferent occasions, so one has satisfaction by using a writinginstrument for all purposes.

For the sake of easy cross references between the description of each preferred embodiment of the present inven-tion, the same reference number and affixed (when required) with alphabetical capital letter is assigned.
In the replaceable pen-nib of the writing instrument in this invention, the main structural improvement ~ncludes, firstly, an optionally removable part between the front part of pen holder and pen-nib, and secondly, an optionally replace-able part in the rear part of the pen holder where spare pen-nibs of different gauges may be stored.
The writing instrument of the present invention, as shown in Fig. 1, comprises a ball pen-nib 10 which uses an aqueous ink solution, a capillary type ink guiding element 20, pen-nib cover 32, pen holder 30, ink storage cartridye 50, adapter 40, and packing 60. The pen-nib 10 is held by an adapter 40 and tightened by means of screwed-in pen-nib cover 32 to the pen holder 30.
1~ ,`.;
~ ?;~
~L~L6~ 5 The construction of adapter 40 is shown in Fig. 4A.
Grippers 41-41 are an integral part of adapter A0. The front screw ~2 of the flange 44 is screwed together with pen-nib cover 32 and the rear screw 43 is fitted by screwing with the front part of pen holder 30. The space 410 between grippers 41 and 41, enables the passage of air as well as ink flow.
On unscrewing the pen-nib cover 32, it is very easy to remove pen-nib 10. By the reverse operation, the pen-nib 10 is tightened to the pen holder 30. When the pen-nib 10 is worn out, a spare pen-nib 101 in the rear part of pen holder may be taken out by unscrewing rear end cover 35 to replace the worn out one.
The capillary type ink guiding element 20 may be as in Fig. 2A or 2B. In Fig. 2A, a plurality of capillary type grooves 24, 25 are cut in the outer surface of element 20 from the middle larger diameter portion 23 to the front smaller diameter portion 21 thereof. The pen-nib 10 contacting the front end of the element 20 is as in Fig. 3A. In Fig. 2B the capillary tube guiding core 131 in the pen-nib 10 is an integral part of said ink guiding element 20 and thus the replaceable pen-nib is as in Fig. 3B. In this manner, the type of the pen-nibs stored in the rear part of the pen holder are changed accordingly.
The capillary element 20 and ink guiding core 131 are mounted in a relationship of face-to-face abutment as shown in Fig. ~. On the closely abutting face of the capillary member 20 is formed one or more radial or crossed capillary grooves which are extensions of the longitudinal capillary grooves 24, 25 on the outer surface of said capillary member 20, so as to effectively enhance its capillary ink-guiding functlon and enable the fitting of many different gauges of writing nib, for example, a baJ1 point pen-nib 10 to induce the ink from said - "
ink reservoir 50 ~lowing to the pen-nibs 10 mentioned above or to replace thereof for writing. Since the capillar~ grooves at the front end face of said capillary member 20 effectively enhance the capillary function of conveying ink from the ink reservoir 50, each of such different gauges of pen-nibs, after being fitted on the pen holder 30, can be used for smooth and fluent writing.
Another embodiment of the replaceable pen-nib of the present invention is shown in Figs. 4B and 5. The pen-nib and the pen-nib cover 32 are combinèd as a single unit and are fixed on the front part of the pen holder 30 by being either slipped on or screwed-on.
It is to be understood that the pen-nib cover 32, as shown in Fig. 5, is screwed on the pen holder 30 while the spare pen-nib 100 with its cover 320 is fixable by either being slipped on or screwed-on to the rear part of the pen holder 30.
It will be appreciated that according to the present invention, the replaceable nib writing instrument may also be a signature pen using a semi-oily ink. As shown in Fig. 6A, a conventional signature pen comprises an ink storing cellulosic element 50A in the pen holder 30A, thus allowing passage of the ink to pen-nib lOA through the ink guiding core 20. The writing instrument of this kind commonly available in the market, usually has an integral pen-nib cover and pen holder being cast or formed together and fitted tightly to the front end of the pen holder by force. This kind of construction is based upon the convenience of manufacturing as well as assembling processes instead of facilitating the replacement of parts, consequently, it is not advisable to replace pen-nib by hand. In the replace-able nib writing instrument of the present invention the pen-nib cover has a structure 32A in Fig. ~A. The pen-nib cover 32A
has a length to be easily held by fingers and can be screwed , ~, . .
~G98~
on the front part of pen holder 30A. The pen holder 30~, as usual, has an air equalizing hole 33. In this embodiment, pen-nib lOA is fltted to the inside of pen-nib cover 32A, and the front half of ink guiding core 20A is in turn closely held to the inside of pen-nib lOA.
When replacing pen-nib lOA, all one has to do is to unscrew the pen-nib cover 32A, the pen-nib lOA together with the front half core 20A Will be separable from the pen holder 30A. Also, when screwing pen-nib cover 32A Gn the pen holder 30A, the frGnt half core 20A Will engage ~ith the main guiding core 20 so as to have a smooth ink flowing effect by capillary action.
The main ink guiding core 20 in the above mentioned embodiment may be made in a single piece as shown in ~ig. 6B, which will directly reach the pen-nib lOB. When unscrewing the pen-nib cover 32B from pen holder 30B for replacement, only the pen-nib lOB will be separated, leaving the guiding core 20B
e~tending from the pen holder. This kind of construction is more favorable for the slip on type construction of the ink 20 storage cartridge 50B.
It is to be emphasized that according to the present invention each of the ink guiding cores 20A and 20B also have cut on the outer surface at least one longitudinal capillary type groove 24, 25 to provide for smooth guidance and feeding of ink.
In the same manner as set forth above cellulose pen-nib may also be app]icable to the construction of pen-nib cover of this invention instead of ball point pen-nib mentioned above.
The present invention rela-tes to a writing instrument and more particularly, to a writing instrument having manually separable parts of nib and pen holder so that either new nibs or different pen point gauges can be arbitrarily changed.
Conventional writing instrumen-ts, such as cellulose~
nib or ball-nib pens for use in signing have a fixed or all-in-one part of the nib and pen holder because of favorable pro-duction in the assembly line. Therefore, it is impossible to separate nib from pen holder without proper tools or without destruction.
