Remote cylinder lock with split, radial pin tumblers.

Patented in the German Empire on February 19, 1921.

The subject of the present invention relates to the known combination two types of lock, namely a cylinder lock with radial, split pin tumblers and a cylinder lock, in which the pin tumblers are shifted parallel to the key shaft by rods be moved.

However, this known combination has the disadvantages, firstly, that the whole

Lock with its pin tumblers is in the door and consequently against violent Attacks from outside are not protected, and secondly, that the design of the lock makes one Diameter of at least 30 mm and a corresponding hole in the door claimed and, thirdly, that the Chopsticks for moving the pin tumblers have different lengths, which in turn means that the gradations of the Key from this can be recognized from the outside and thereby the security of the lock is greatly reduced.

By the remote cylinder lock forming the subject of the present invention all these evils avoided.

The features of the invention are primarily to be seen in the fact that the remote cylinder lock is protected against violent attacks from the outside, because the lock housing with the tumbler pins and the turntable with the associated release pins are not, as before, in, but behind the door and through the fixed connection of the Turntable with the rotary cylinder of small diameter located in the door, thus the hole in the door, with simultaneous Use of a small key, only of small diameter (10 to 11 mm).

Further features of the invention are the arrangement of slides of equal length, the ends of which protrude the same distance from the keyhole when the lock is locked, hence the Graduations of the key are not recognizable from the outside and thus the security of the lock is increased, and in the arrangement of the guides for the tumblers and slider, by which novel and peculiar arrangement it is achieved that the Possibility is given, the rotating cylinder lying in the door with two different to provide broad approaches, for the purpose of the correct introduction of the key and the impossibility of removing the key if not the turntable Is blocked.

Finally, it should be emphasized as a feature of the invention that the slides of the subject of the invention are provided with lifting surfaces for moving the split tumbler pins, which do not have to be designed differently as in the known lock, but have the same wedge-shaped design and each slide ends in a cylindrical approach which a common spring presses and which lugs simultaneously serve to accommodate the release pins under spring pressure. In the drawing, the remote cylinder lock is shown in Fig. 1 in a vertical section along the line AB of Fig. 4, i.e. in the rest position, and in Fig. 2 in readiness for opening or closing, while Fig. 3 shows the side view in section the line EF of Fig. 1 and Fig. 3a shows a cross section along the line RS of Fig. 3. Fig. 4 is a horizontal section along the line CD in Fig. 1. Fig. 5 illustrates the various positions of the slider corresponding to the key gradations shown in Fig. 6 after the key has been inserted, ready to open or close. Fig. 7 is the turntable with the rotary cylinder firmly connected to it in a horizontal section along the line CD in Fig. 1. Figs. 8 and 8a are cross-sections through the rotary cylinder along the line GH and KL in Fig. 4, and Fig 9b one such according to the line 0-P through the gradations of the key shown in Figs. 9 and 9a.

The lock housing α accommodates the well-known pin tumblers of equal length (e.g. six pieces) S ₁ , s "... which are under pressure from the springs /, /, and has a tubular extension b, from a length corresponding to the door thickness. In the lock housing α , the rotary or cylinder disk c is installed, which is firmly connected to a rotary cylinder d mounted in the tubular extension b.

In the turntable c , on different sides, bores V ₁ , v "... are combined in groups for the release _{pins A 1} , h" ... acting on the tumbler pins S ₁ , s. _Z ... as well as incisions e _x , e "... (Fig. 7 and 7a) for receiving the lifting surfaces p, p ... the slides g _v g" ... incorporated radially and approximately radially opposite one another in such a way that the spaces between the bores V ₁ , v " . .. at their inner exit from the turntable c are different, whereby the remaining space the arrangement of differently wide approaches Ji ₁ , k " on the rotary cylinder d (Fig. 7 and 8a) and the associated through the lugs U ₁ , u ₂ am At the end of the extension b (Fig. 3 and 3a) formed grooves and the associated grooves I ₁ , L (Fig. 6 and 9) in the key, which are necessary for the correct introduction of the key and for the rotation of the cylinder d and achieved at the same time is that the key can only be removed when the pin tumbler n S ₁ , s "... and A ₁ , A ₂ ... block the turntable c.

On the rotary cylinder d , in a known manner, the locking lever or key bit η for moving the lock bolt is attached to the rear end.

By using the slider you can still use the tumblers and the lock behind the door, even with the strongest doors, the small diameter key, also be kept very short, and since the same: has no beard - like the key of the combination lock mentioned in the introduction - not to be damaged.

Claims (3)

Patent Claims: 1. Remote cylinder lock with split, radial pin tumblers, characterized in that of the pin tumblers consisting of tumbler and release pins, the tumbler pins (S ₁ , S ₂ ...) In a disk-like lock housing (a) and the release pins (A ₁ , A ₂ ...) are stored in a turntable (c) and these lock parts are not, as before, in, but behind the door and the turntable (c) with a rotary cylinder built into the door (d) in which a slide is parallel to the axis (§Ί) ^ 2 · · ·) are permanently connected. 2. Remote cylinder lock according to claim 1, characterized in that the slide (^ ₁ , g ₂ ... ) guided in the rotary cylinder (d) are all of the same length, whereby when the lock is locked, the slide ends all protrude equally far from the keyhole and thus the different gradations (T ₁ , r ₂ ...) of the key are not recognizable from the outside and the slide for moving the release pins (A ₁ , A ₂ ...) have lifting surfaces (p) of the same wedge-shaped design and each in one approach (o) end, which is intended, on the one hand under the pressure of springs (. Z _1, f _2..) stationary pin tumblers (^ _1, S ₂ ..., and a _1, a ₂ ...) and on the other hand also take up the pressure of the common spring (m) on the slide (gi> S2 · · ·). 3. Remote cylinder lock according to claim 1 and 2, characterized in that in go of the turntable (c) on different sides combined in groups pin tumblers (^ ₁ , S ₂ ... and A ₁ , A ₂ ...) and slides (^ ₁ , g- "...) are radially and approximately radially opposite each other in such a way that the spaces between the bores (V ₁ , V ₂ ...) Are different when they exit from the inside of the turntable (c) , whereby the remaining space makes the production of different wide approaches (Ji ₁ , k ₂ ...) on the rotary cylinder (d) for the correct introduction of the key and at the same time it is achieved that the key can only be pulled out when the pin tumblers lock the turntable (c) .
