Description

Lock with tumbler safety slides Addition to patent .... (Pat.-Aniii. B 85 434 Ic / 68a). The main patent relates to a lock with tumbler safety slides, in which a number of locking plates corresponding to the number of tumbler safety slides are assigned, in which each locking tooth, preferably sitting on the tumbler safety slide, has its own entry opening corresponding to the associated beard step of the key Lock plate is assigned.

The relevant design according to the main patent brings about the known locks with tumbler safety slides the advantage one higher locking security and greater combination options. The lock is also much more advantageous in terms of production and use, for the manufacturing advantages, it is particularly important that different Spe rrplatten be assigned to one and the same basic type, if necessary are combined into a usable block. In further development of this embodiment According to the main patent, the present invention proposes that the backup plates are transversely to the direction of their ratchet engagement opening and lockable. As a result this configuration is achieved that no longer for each beard combination A separate set of lock plates must be made which are attached to the appropriate Place the ratchet engagement opening. The adjustability of the locking plates Rather, it allows the same locking plates to be used and these are then adjusted so that the ratchet engagement opening at the for the corresponding beard step of the key is in the correct place. In this position the locking plate is then determined. The design is not just manufacturing technology advantageous, but also in terms of usage. The lock can by loosening the Finding these backup plates and other types of setting the same at any time on a other beard combination can be matched, for example, if the corresponding The key was lost and, for security reasons, a key was not returned the same beard combination should be selected.

According to the invention, there is an advantageous design, in particular in In terms of the fact that the locking plates in a box-shaped Housing are arranged and a transverse to the locking teeth # -ineingriffsausnehmun.gen have trending Sclilitz that before.

one or more fixing screws is inserted. Ah tightening the locking screwdriver accordingly. still exists at the same time the possibility of the #b 41 so initially properly tied security pJatten through further aids, e.g. 13 '. by serrated slides entering into notches in the plates, Finally secure the bolts or the like if this is necessary.

According to Lrfindun.51, it is advantageous for easy repositioning and locking if there is an opening above the locking screw in the lock cover for inserting an actuating tool. This attacks C> z2 on the locking screw of the locking plates. The possibility of combination and the locking security is significantly enhanced if, according to the invention, the ratchet teeth are formed from steel wire pins used. The steel wire pins braLiciien only have a very small diameter. It was found that the stalildralite pins, which are loaded exclusively in their axial direction, withstand physical stresses, including those caused by unauthorized opening attempts. The Schinalfl.; Ichen of the Stahldralitstifte make it possible in a very favorable way> to provide teeth on the sections between the ratchet engagement opening parts in order to counteract the scanning process in a manner known per se. In order to produce a reversible lock on the same construction basis, i.e. a lock which can only be unlocked depending on the key with which it was brought into the locked position and which can be brought into the closed position with keys of different beard sizes , is invented (, un # _ #,. According to the solution, that the locking plates are in Sc'liliel ") _ position, by means of projections arranged on them, which enter slots in cari-like retaining plates, in their locking combination for locking used key are defined. in this design, so the blocking plates are not final and determined in principle 'Itzlic]. They are each defined only in the Scliließkombination that the attaching and removing close equivalent of the castle benutzen.Schlüssel. Line this flinsicht especially structurally advantageous The design is according to the invention that the projections on the ratchet engagement opening are arranged on the opposite flank of the locking plates and the comb-like retaining plates move into the holding up position after the locking slats have been arranged during locking. Finally, according to the solution of the invention, it is still possible in a simple manner to assign an emergency key function to the lock. This means that the lock can be opened with the help of an emergency key, regardless of which lock combination the lock is set to from home or - in the case of the conversion lock - with which key the lock has been brought into the closed position. This is achieved according to the invention in that the locking plates can be displaced into a certain locking combination corresponding to that of an emergency key by means of an emergency locking bit built into the lock case, which disengages the comb-like retaining plates when turned into its operative position. With this design, therefore, usually only a single emergency key is supplied to each lock; this has the same beard combination as the emergency closing beard that is in the castle by default. After bringing the emergency key bit into the operative position, the owner of the emergency key can then open the lock.

According to the invention, an advantageous design consists in that the rotatable emergency key bit is located sideways from the control projections which run at an angle to the locking plates. Such a design also fits favorably into the overall structure of the lock. According to the invention, a special embodiment to decouple the lialte function of the holding plates consists in the holding plates, which are longitudinally displaceable transversely to their comb slots, are acted upon by jaws on both sides, which pivot away from the holding plates when the emergency closing beard is turned and release them for longitudinal displacement. The retaining plates themselves can then remain in engagement with the projections of the locking plates. Each projection of each locking plate protrudes into a comb slot in the retaining plate. The Ilaltefuri - * .- Z - # --- 22.nn of the Iialteplatten is omitted because the lial-Lz; plates can shift themselves when the emergency key bit is swiveled in. - For safe operation and a simple construction, it is advantageous' when the jaws are controlled by iiiiteinander käninenden 7ahnsegmenten invention, one of which sits on the Notschlüsselbart i; oth jaws are then controlled synchronously when turning the Notschlüsselbartes from its impact position.. 1 Fig a view against the Registered lessons of the lock according to the invention with removed lock cover in the open position:., the jaws tighten again from both sides stop side, the holding plates in the fixed position the object of the invention is illustrated on the accompanying drawing in three embodiments show Ls...

According to the first embodiment according to Figs. 1 to 6 , the lock case has the lock plate 1, the faceplate 2 and the lock cover 3. A latch 4 is actuated by a driver 51 seated on the key socket 5 , which also switches the locking tumbler 6. For this purpose, the locking lug 61 of the locking tumbler 6 engages in corresponding recesses 41 of the bolt 4 and thus blocks the bolt.

The locking plates 7 are mounted above the locking tumbler 6 and can be displaced parallel to the locking tumbler 6 by the bit steps 81 of the key 8 (see FIGS. 3 and 4). Having for guiding the locking plate 6 and the closing plate 7, the slots 9, are used in the lock case fixedly arranged stay bolts 10, the lock plate 6 by means of the coil spring 11 and the closing plates 7 are acted upon by the springs 12th Above the closing plates 7 run out in a slope 13 . This bevel 13 is in contact with the corresponding bevel of the tumbler safety slides 14, which are displaced in the direction of the faceplate 2 when the closing plates 7 are lifted (see FIG. 3). Are supported and guided the tumbler securing slide 14, 15 by means of the bolt arranged in the lock case a continuous contact of the bevel of the tumbler securing slide it 'e-, egen the slope 13 of the locking plates 7 is brought about by springs sixteenth

Each locking tooth 17 located below the tumbler safety slide 14, which is formed by an inserted steel wire pin, is assigned its own inlet opening 18 on each locking plate 19 , corresponding to the associated bit 81 of the key 8. These securing plates 19 are arranged in a box-shaped housing 20 and have a direction transverse to the ratchet tooth engagement openings 18 slot 21. The slot 21 is penetrated by a locking screw 22 and captures the locking plates 19 together dei., I housing 20 6 to the lock plate An additional , the housing. The screw 23 penetrating through 20 secures the fixed position relative to the locking plate 6. The edge of the securing plates 19 is toothed to make the Ilobb opening process more difficult.

An opening 24 is provided above the locking screw 22, which allows an operating tool, such as a screwdriver, to be pushed through. In a further development according to the second embodiment according to FIGS. 7 to 14, the lock designed as a reversing lock has the bolt 4, which has a slot 411 for the emergency locking bit 25 to enter. This slot 4 ″ is widened in accordance with an angle 26 guided in it, one of which is 26 ' against the axis of the emergency key bit and the other leg 26 ″ partially enters a recess 41 of the bolt 4 (see Fig. 7). The seated on the key driver bushing 5 5 "betae term the latch 4, the lock plate 6 and the slide plate about superimposing 27th

The comb-like retaining plates 28 are held by dowel pins 29 on the locking plate 6 . In the closed position (see FIG. 9), the projections 31 arranged on the locking plates 191 , which are arranged on the flank of the locking plates 191 opposite the locking tooth inlet openings 181 , enter the slots 30 of these comb-like lialteplates 28 . The displaceable locking plates 191 have the slots 32 for the pins 33 located on the sliding plate 27 and are acted upon by springs 34.

Control extensions 1-911 are located at an angle to the locking plates 191. Against these places when turning into its operative position (see Fig. 13 and 14) of the Notschließungsbart 25.mit his beard stage 251. The Fig. 13, the uncoupled position shows the comb-like lialteplatten 28 and the locking plates 191 associated projections 31. In this position, one leg 261 of the angle 26 lies on the flattened area 35 of the axis of the emergency locking bit 25, and the locking plate 6 has its starting position due to the spring action. FIGS. 15 to 17 show a further development of the second embodiment. Here, the comb-like retaining plates 28 are mounted on the pegs 291 located on the sliding plate 27 in a longitudinally displaceable manner transversely to their comb slots 30. The comb-like retaining plates 28 have grooves 36 for longitudinal displacement. The retaining plates 28 are held on both sides by jaws 37 and 38 mounted in the lock case, which pivot away from the retaining plates 28 when the emergency key bit 25 is turned into its operative position (see Fig. 17) and release them for longitudinal displacement. This synchronous pivoting away is done by means of the jaws 37 and 38 associated with toothed segments 39 and 40. The Notschlüsselbart 25 as well as of the associated jaw 37 it is associated with the toothed segment. 39

The mode of operation is as follows: In the lock shown in Figs. 1 to 6 , starting from the open position (see Fig. 1), the key 8 is inserted into the key socket. The driver 51 sitting on the key socket 5 actuates the bolt 4 and the locking tumbler 6. According to the gradation of the beard steps 81 , the locking plates 7 are raised and the tumbler safety slides 14 are displaced. After this classification of the tumbler locking slide 14, the driver 51 controls the locking plates 19 in the floated position so that the locking teeth 17 enter their associated entry openings 18 of the locking plates 19 (see Fig. 3). After the closure has taken place, the strikers 7 and the ZWialtungs safety slide 14 return to their basic position (see Fig. 1).

-If the lock is to be set to a new key, an operating tool is inserted through the opening 24, the locking screw 22 is loosened and the locking plates 19 are locked in and out by longitudinal displacement according to the beard steps of the new key.

The lock illustrated in Fig. 7.bis 14 is closed such that the inserted key 8, starting from the open position (see Fig. 7) over-the-fitting of the key bushing 5 Mitnehi beer 511 the latch 4, the lock plate 6 and the sliding plate 27 switches. In accordance with the beard steps, the tumbler locking slides 14 are shifted over the locking plates 7 in the direction of the faceplate 2. The locking teeth 171 of the tumbler locking slide 14 enter the inlet openings 181 of the locking plates 191 and move them. The comb-like retaining plates 28 moved upward from the locking plate 6 receive the projections 31 seated on the locking plates 191 in their slots 30 . After completion of the closing process die.Zuhaltungs-safety slide 14 and the locking plates 7 are bent back into their Position reached while the barrier plates 191 remain with the comb-like Ilalteplatten 28 in clutch engagement. Opening is only possible with a key that has the same bit as the key with which it was locked, since the locking plates 191 are arranged in accordance with the lock combination of the key used for locking. If the emergency key bit 25 is actuated, that is to say pivoted about its axis so that the bit steps of the same align the control extensions 1911, the locking plate 6 with the locking lug 61 belonging to it enters deeper into the recess 41 of the bolt 4, since the angle 26 is on the flattening 35 of the Notschlüsselbartachse set and hence the recess 41 of the bolt 4 has completely released. the comb-like holding plates 29 are likewise moved downwardly with the locking plate 6, so that the projections are free 31 of the locking plates 191 (see Fig. 13). the barrier plates 191 are entspre thereafter According to the locking combination of the emergency key bit 25. It can only be unlocked with a key which has the bit steps corresponding to the emergency key.

In Figs. 15 to 19 the closing process takes place in the same way as in the second embodiment. The emergency key bit 25 is pivoted by means of an actuating tool. Here, the bit stages 251 28 contact against the cam projections 19 'and align the gekLippelten with the --kainmartigen holding plates 28 blocking plates 191 corresponding to the bit stages 251 of the emergency key from .. because the jaws 27 and 28 in synchronism with the crests of the toothed segments 39 and 40, the holding plates released (see Fig. 17).

The unlocking can now be done with a bit corresponding to the emergency key Key happen.

A smooth operation of the lock is favored if the possibly formed ratchet teeth 171 (see Fig. 7 to 19) are tapered at their entry end, or the ratchet engagement openings 181 widen slightly on the entry side. The same solution concept is implemented on the comb slots 30 by widening the same on the mouth side.

To achieve a lock with a master key function, accordingly the solution according to Ilauptpatent a locking tooth of the tumbler safety slide several locking tooth engagement openings in the Be assigned to a blocked position.
