再如第二圖、第三圖及第四圖所示，前述該子母珠鎖心的兩組第一內鎖珠3，其中的一組的內母珠31的一內端311設有一與鑰匙孔21方向對齊的剖槽312；且該內 母珠31的內端311的兩側分別形成一斜面313，而剖槽位312於兩斜面313之間，因此當滾珠鑰匙6***時，能夠使滾珠613通過剖槽312避免觸動內母珠31，而使滾珠613只推動內子珠32，至於有剖槽312的內母珠31的內端311則由上述溝槽611的槽底面614來推動，俾將該組第一內鎖珠3推到正確的位置。如第五圖及第六圖所示，為使該內母珠31的剖槽312能對齊滾珠鑰匙6***時的滾珠613，該內母珠31的一側具有一導引凸部314，導引凸部314係一凸塊；而相匹配的該第一鎖珠孔22與第二鎖珠孔13的一側壁設有容納導引凸部314的導引凹部221、131，導引凹部221、131係為一導槽。如第七圖所示，亦可將上述的導引凸部314設在內母珠31的中間處，因此第二鎖珠孔13不必設有上述的導引凹部131，以第二鎖珠孔13的圓形孔狀也能使內母珠31有活動到第二鎖珠孔13的的空間。 As shown in the second, third and fourth figures, the two sets of first inner locking beads 3 of the sub-bead lock core, one of the inner ends 311 of one of the inner mother beads 31 is provided with a a slot 312 in which the keyhole 21 is aligned; and the inner A beveled surface 313 is formed on each of the two sides of the inner end 311 of the mother bead 31, and the slotted position 312 is between the two inclined surfaces 313. Therefore, when the ball key 6 is inserted, the ball 613 can be prevented from touching the inner bead 31 by the slot 312. The ball 613 pushes only the inner bead 32, and the inner end 311 of the inner bead 31 having the slot 312 is pushed by the groove bottom surface 614 of the groove 611, and the first inner locking bead 3 is pushed. Go to the right place. As shown in the fifth and sixth figures, in order to enable the groove 312 of the inner bead 31 to be aligned with the ball 613 when the ball key 6 is inserted, one side of the inner bead 31 has a guiding protrusion 314. The guiding protrusion 314 is a protrusion; and a matching side wall of the first locking bead hole 22 and the second locking bead hole 13 is provided with guiding recesses 221, 131 for receiving the guiding protrusion 314, and the guiding recess 221 The 131 system is a guide channel. As shown in the seventh figure, the guiding protrusion 314 may be disposed at the middle of the inner bead 31, so that the second locking bead hole 13 is not necessarily provided with the guiding recess 131, and the second locking bead is provided. The circular hole shape of 13 also enables the inner mother bead 31 to have a space to move to the second lock bead hole 13.
本發明之子母珠鎖心與滾珠鑰匙6配合使用時，如第五圖所示，將滾珠鑰匙6的鑰匙胚61***鎖心2的鑰匙孔21，將使滾珠613的周圍頂推第一內鎖珠3的內子珠32與無剖槽312的內母珠31，而有剖槽312的內母珠31的內端311則被溝槽611的槽底面614頂推。再如第六圖所示，在有第二內鎖珠24與第二外鎖珠15的實施例中，當滾珠鑰匙6的鑰匙胚61***時，則同時利用溝槽611的槽底面614頂推第二內鎖珠24，至於其他部位的鎖珠則採用習知的方式推動，因此能利用滾珠鑰匙6將全部的鎖珠推到正確的位置，進而可轉動鎖心2開鎖。 When the sub-bead lock of the present invention is used in conjunction with the ball key 6, as shown in FIG. 5, the key blank 61 of the ball key 6 is inserted into the key hole 21 of the lock core 2, so that the circumference of the ball 613 is pushed first. The inner bead 32 of the locking bead 3 and the inner bead 31 of the non-grooving groove 312, and the inner end 311 of the inner bead 31 having the notch 312 are pushed up by the groove bottom surface 614 of the groove 611. As shown in the sixth figure, in the embodiment having the second inner locking bead 24 and the second outer locking bead 15, when the key blank 61 of the ball key 6 is inserted, the groove bottom surface 614 of the groove 611 is simultaneously utilized. The second inner locking bead 24 is pushed, and the locking beads of other parts are pushed in a conventional manner, so that all the locking beads can be pushed to the correct position by the ball key 6, and then the locking core 2 can be unlocked.
如第十二圖所示，若使用不匹配的滾珠鑰匙6進行開鎖，當滾珠613直徑太小時，兩組彈性元件5將分別推動第一外鎖珠4及第一內鎖珠3的子母珠，因此子母珠仍栓在鎖殼1與鎖心2之間；而且，如果溝槽611的槽底面614深度不對時，也不能將第二內鎖珠24與第二外鎖珠15推動到正確的開鎖位置。反之，如第十三圖所示，如果滾珠613直徑太大時，將會推動第一內鎖珠3太多，以致第一外鎖珠4及第一內鎖珠3的子母珠仍栓在鎖殼1與鎖心2之間。再者，即使滾珠613的直徑能正確吻合，若滾珠鑰匙6的溝槽611的槽底面614深度不正確，也不能將有剖槽312的內母珠31及第二內鎖珠24與第二外鎖珠15推到正確位置。由此可見，本發明根本不能被萬用鑰匙或其他開鎖工具以不正當的方式開啟。而且，本發明滾珠鑰匙6的滾珠613也不是用習知的鑰匙複製機就能加工出來，必須鎖具原廠提供滾珠613才能組成滾珠鑰匙6，因此能預防鑰匙被複制。 As shown in Fig. 12, if the unmatched ball key 6 is used for unlocking, when the diameter of the ball 613 is too small, the two sets of elastic members 5 will respectively push the first outer locking bead 4 and the first inner locking bead 3 Beads, so the mother beads are still tied between the lock case 1 and the lock core 2; moreover, if the groove bottom surface 614 of the groove 611 is not deep enough, the second inner lock bead 24 and the second outer lock bead 15 cannot be pushed. Go to the correct unlock position. On the contrary, as shown in the thirteenth figure, if the diameter of the ball 613 is too large, the first inner locking bead 3 will be pushed too much, so that the first outer locking bead 4 and the sub-parent of the first inner locking bead 3 are still tied. Between the lock case 1 and the lock core 2. Furthermore, even if the diameter of the ball 613 can be correctly matched, if the depth of the groove bottom surface 614 of the groove 611 of the ball key 6 is not correct, the inner bead 31 and the second inner locking bead 24 having the notch 312 and the second can not be used. The outer locking bead 15 is pushed to the correct position. Thus, the present invention cannot be opened at all by a universal key or other unlocking tool in an improper manner. Further, the ball 613 of the ball key 6 of the present invention can be processed not by a conventional key copying machine, and the ball 613 must be provided by the original manufacturer to form the ball key 6, so that the key can be prevented from being copied.
另外，如第十四圖所示，本發明該滾珠613中央的孔6134直徑可大於軸銷616，並設定兩組彈性元件5其中的一組的彈力較大，例如圖中下方的彈性元件5的內螺旋彈簧51及外螺旋彈簧52彈力較大於上方的彈性元件5，因此當滾珠鑰匙6***時，使彈力大的一組彈性元件5頂推其第一外鎖珠4與第一內鎖珠3，並將滾珠613推往另一方向，使滾珠613能將兩組第一內鎖珠3推到正確的位置，由於孔6134的直徑能控制滾珠613被推動的幅度，非正確的孔徑將無法發生作用，如此更能增進開鎖的難度。 In addition, as shown in FIG. 14, the hole 6134 in the center of the ball 613 of the present invention may have a larger diameter than the shaft pin 616, and set one of the two sets of elastic members 5 to have a large elastic force, for example, the lower elastic member 5 in the figure. The inner coil spring 51 and the outer coil spring 52 have a larger elastic force than the upper elastic member 5, so when the ball key 6 is inserted, a group of elastic members 5 having a large elastic force pushes the first outer lock bead 4 and the first inner lock. Bead 3, and push the ball 613 to the other direction, so that the ball 613 can push the two sets of the first inner locking bead 3 to the correct position, because the diameter of the hole 6134 can control the amplitude of the ball 613 being pushed, the incorrect aperture It will not work, which will increase the difficulty of unlocking.
綜上所述，本發明子母珠鎖心及開啟子母珠鎖心之滾珠鑰匙，已確具實用性與創作性，其技術手段之運用亦出於新穎無疑，且功效與設計目的誠然符合，已稱合理進步至明。為此，依法提出發明專利申請，惟懇請 鈞局惠予詳審，並賜准專利為禱，至感德便。 In summary, the ball key of the mother-bead lock and the opening of the mother-bead lock has been practical and creative, and the application of the technical means is novel, and the effect is in line with the design purpose. It has been said that reasonable progress has been made. To this end, the invention patent application was filed according to law, but the bureau was requested to give a detailed examination, and the patent was granted as a prayer.
