The specific embodiment

The present invention is to pay at the lock bolt of common the dialing lock to add drive division to achieve these goals, can utilize censorial master key that lock bolt is turned to lockset position of coupler forcibly from the position of locking.

On the airport, the procurator makes the lock bolt of the dialing lock of locking turn to forcibly lockset position of coupler with master key when checking, again locks after inspection.Because case and bag are locked all the time during except inspection, and only have the procurator of authority can hold master key, so the passenger can deposit the case and bag of locking relievedly at check-in counter.

Fig. 1 is the front view with case and bag 10 of code lock used for suitcase and bag of the present invention, the 1st, the case and bag main body, the 2nd, case lid, the 3rd, handle, the 4th, the castor of mobile usefulness, the 5th, the handle of mobile usefulness, the 6th, center lock, comprise common the dialing lock 20 and the operating portion 50,7th by censorial master key operation of the present invention, be used to the sidebuckle of opening case lid 2.2l is the driver plate, the 71st of the dialing lock, and sidebuckle pushes away handle when uncapping.

Form oval after the plectane both sides excision of the keyhole plate that the present invention will rotate simultaneously with the operation of master key, when the procurator opens the dialing lock with master key, the section of tinting appears in this cut part,, can prevent from that the procurator from forgetting again to lock just at unlocking condition after inspection with the prompting the dialing lock.

Fig. 2 and Fig. 4 are the front views after the center lock with case and bag 10 partly takes out, Fig. 3 and Fig. 5 are that the master key operating portion 50 of further procurator being used takes out the rear front view that amplifies, Fig. 2 and Fig. 3 are the states of (containing the occasion that the procurator locks again after inspection) after the passenger locks, and Fig. 4 and Fig. 5 are the states the procurator opens the dialing lock of locking when checking with master key after.

The operating portion 50 that center lock 6 is used by common the dialing lock 20 and master key consists of.The operating portion 50 that master key is used has master key keyhole 52, the keyhole plate 51 of rotating with key is joined with the header board 53 of overlapping operation section 50, as shown in the figure, keyhole plate 51 is that formation after the both sides excision of plectane is oval, such as Fig. 2, shown in Figure 3, after locking with master key, the part of keyhole plate 51 and header board 53 is just in time overlapping, and with the key 90-degree rotation when unblanking, shown in Figure 5 such as Fig. 4, the header board that is positioned at keyhole plate 5l both sides cut-out can be seen, therefore as long as that part 54 that is positioned at keyhole plate 5l cut-out of header board 53 is coated for example red the sort of eye-catching color, the time marquis who unblanks with master key, just such as Fig. 4, shown in Figure 5, just can very clearly know that from the outside lock is in open mode, thereby can prevent that the procurator from forgetting after inspection locks.

Fig. 6 is the top view of the lock bolt 30 of this dialing lock, and Fig. 7 is the end view drawing of seeing Fig. 6 from the T direction, and Fig. 8 is the side view of seeing Fig. 6 from the S direction, and the straight line 3l among the figure is the pivot center of lock bolt 30.The formation of the dialing lock and effect are well-known technology.For the ease of understanding the present invention, at this brief description, the 33rd, the passing through of driver plate arranges the pad that rotates with driver plate at driver plate in the hole between driver plate.Form place's recess at pad, on lock bolt 30, relative position the protuberance 34 that engages with this recess is being set each other with the recess of pad.

Lock bolt 30 because of elastic force to centered by pivot center 31 to the P direction of Fig. 7 by reinforcing.And make the recess of pad consistent with the protuberance 34 of lock bolt 30 such as rotating driver plate 2l (with reference to figure l, Fig. 2, Fig. 4), just protuberance 34 engage with the recess of pad, so just centered by pivot center 3l and in Fig. 7, rotate to the P direction.When lock bolt in the dialing lock 30 is positioned at horizontal level as shown in Figure 7, just suppress action with the bar that pushes away handle 7l (with reference to Fig. 1) interlock of sidebuckle 7 with the end face 32 of pivot center 3l opposition side, push away handle 71 and also can not move even press, become locking state.

Thereby if therefore driver plate 21 is turned to setting number so that the recess alignment of pad engage with the protuberance 34 of lock bolt 30, then as previously mentioned, lock bolt 30 namely is disengaged the restriction with the bar that pushes away handle 71 interlocks because elastic force rotates to the P direction of Fig. 7, thereby lock is opened.

On the lock bolt 30 of the dialing lock of the present invention, except these common formations, also at one end form tab 35 and be used as the drive division with the master key operation by the procurator.Tab 35 can be arbitrary shape, and the example shown in the figure has the press section 36 of inclination bending.After locking the dialing lock of case and bag, the passenger after check-in counter is deposited, when the procurator thinks that being necessary to open case and bag checks, just uses the master key of holding.So, just pinned the press section 36 of tab 35 by suitable mechanism, lock bolt 30 is rotated to the R direction of Fig. 7, as previously mentioned, because pushing away the end face 32 of the action of handle 7l, inhibition broken away from restriction site, therefore can press and push away handle and open case and bag when usually unblanking (when according to password and with the aligned in position of the recess of pad lock bolt 30 being rotated compare the direction of rotation of lock bolt 30).

After check finishing, return the original place and remove the pressing of press section 36 if check the choush key, just lock bolt 30 rotates to the P direction because of elastic force, and again return locking state.As described in when Fig. 4 Fig. 5 is illustrated, when opening the dialing lock with master key, keyhole plate 51 is rotated, and the section 54 that tints exposes, and a glance just can be judged and be in the unlocking condition, so forgets the danger of locking again after can preventing from checking.
