Teleï¬ex;18. Mouth;19. Cap.The diï¬erences between a candy bar pen of the application and existing intrapencandy lie in, several small projectures are located on the back of lower end of a barrel,moreover several small projectures are also located on a principal axis sliding in a barrel,the latter can slide in the little guiding grooves in front of the barrel, when an innercircle of numeric cipher code is mounted on a barrel, both sets of small projectures canbe used for guiding in coordination with the grooves inside the inner circle, when pushthe button enabling the principal axis sliding downwards to the closing position of a topshell, if any of the cipher circles has been turned over a division, then the groove apartfrom the projecture prevents the principal axis from sliding up wards in the barrel andlocked in, then the top shell of candy bar pen cannot be opened.The assembling method and process of components 1-10 in the application aresimilar with existing intrapen candy and shall not be repeated, the assembly sequence ofother components are: 14, 11, 15, 12, 16, 13, 17, 18 and 19, the completed candy barpen after assembling may refer to Fig. 4.Fig. 4 is a front View of a candy bar pen in the application, showing the state of thetop shell being opened and reï¬ll being stored, the cipher codes of a trick lock are in thesequence of 1,2,3 from up to down, the closed posrtion of top shell is shown withdouble) dotted lines in the diagram.Fig. 5 is a back view of candy bar pen in Fig. 4.Fig. 6 is a sectional view taken along the A-A line in Fig. 4, the interior structureof a candy bar pen after assembly may be seen in the diagram.101520CA 02264671 1999-03-02Fig. 7 is a front view of a barrel of candy bar pen of the present invention.Fig. 8 is a sectional view baken along A-A line in Fig. 7, projectures on the back oflower end of a barrel may be seen in the Figure.Fig. 9 is a top view of a barrel in Fig. 7.Fig. 10 is a front view of a barrel, mounted with inner circle 14 of ï¬rst numericcipher code, installed with a principal axis and a button.Fig. 11 is a front View of inner circle 14 turned over a division in anticlock wisedirection in Fig. 10.Fig. 12 is a view of the status in Fig. 10 added with an outer circle 11 of ï¬rstnumeric ciphericode, at this moment a cipher code is 1.Fig. 13 is a plan view of a teleï¬ex in a candy bar pen of the present invention.Fig. 14 is a sectional view taken along A-A line in Fig. 13.Figs. 15-18 show how to alterate a cipher code (top shell is omitted in the diagram),in Fig. 12 the cipher code of ï¬rst circle is 1, then inner circle 15 and outer circle 12 ofthe second numeric cipher code are installed in succession, while the cipher code ofsecond circle is 2, then the inner circle 16 and outer circle 13 of the third numeric ciphercode are likewise installed in succession, at this moment the cipher code of third circleis 3, as shown in Fig. 15.As shown in Fig. 15, the codes being 123 from up to down, if the codes arerequired to change to 122, then ï¬rst a button has to be pushed upwards, the top shellopens',.at this moment projectures on a principal axis shall slide into the groove inside *an inner circle, which cansed the inner circle to be non-rotatable, then turn down theteleï¬ex in anticlock wise direction, see Fig. 16. In Fig. 16, move the third outer circledownwards for a haef dirision, then turn it over one division anticlockaise relative to the101520CA 02264671 1999-03-02inner circle, the state after rotation see Fig. 17, at this moment numeral 2 on the thirdcircle is already at the center, aï¬er pnshing up the onter circle, turn up the teleï¬ex inclockwise direction and lock in, as shown in Fig. 18, now the codes have been alteredto 122. 9If the code of second circle shall be modiï¬ed, when the third outer circle has beenlowered for a half division in Fig. 16, then lower the second outer circle for a halfdivision and turn relative to an innercirele, when the desired numerals have beenacquired, push the two circles up wards in succession, here after the steps are the sameas before. Similarly, when the code of the first circle shall be altered, then three outercircles will be lowered a half division respectively in succession, until the first outercircle rotated and changed the cipher numerals, then push the three outer circlesupwards in succession, ï¬nally turn the teleï¬ex to lock in.Figs 19-21 show how to turn the numeric cipher circle anticlockwise, ussume thecode numerals to be 234 in Fig. 19, lower the button, âthe top shell will be closed, at thismoment if the second and third circles were turned over 1 division respectively, codenumerals 223 as shown in Fig. 20 will be acquired, the principal axis is locked in, thebutton cannot be pushed up ï¬irther, the top shell cannot be opened, at this moment ifthe first and third circles were turned over 2 and 3 divisions anticlockwise respectively,then the numerals changed to 020 as_shown in Fig. 21, in this case the top shell likewisecannot be opened, it can only open on turning to preset code numerals 234 again.Figs 22-24 show how the numeric code circles are turned anticlockwise, similarlysassume the code numerals to be 234 in Fig. 22, when the ï¬rst and third cireles turnedover 1 division clockwise respectively, the numerals will be altered to 335, at thismoment the top shell is locked in and cannot be opened, as shown in Fig. 23, if the10CA 02264671 1999-03-02second circle has been turned over 1 division clockwise, the third circle turned over 3divisions clockwise, then the numerals become 348 from top to botton, at this momentthe top shell cannot be opened as shown in Fig. 24, it might reopen until returning tooriginal numerals 234. 9Figs. 25-28 are the front view, right view, left View and back view of the principalaxis in candy bar pen of the application respectively, Fig. 29 is an enlarged sectionalview taken along AâA line in Fig. 27. The locations of several projectures on the frontlower end of principal axis can be seen in the diagram.Industrial ApplicabilityOn summarizing, a candy bar pen with a trick lock of the application, has a novelstracture, being innovative and may be used as a writing tool.
