State of the art - _; _: - "." - ^:

Security lock cylinder with. Plate tumblers, consisting of inner cylinder, plate tumblers with cushioning, outer cylinder and key, are made from solid single parts, similar to pin cylinders. as well as the manufacture AuBenzjrlinder, difficulties are a, uf, if it ^is: it orld hand-, the inner cylinder in the outer cylinder bye - to fix. Man. uses dowel pins, circlips, etc. to do this. It then turns out that the small diameter. The end of the inner cylinder is "impermissibly weakened" by these fastening means, ... because the closing movement must ultimately be transmitted via the driver to the lock parts edit ,,; Grinding and polishing processes must be switched on in order to achieve a reasonably good appearance.. " _: . ■■■ - -.-. ί

The previous lock cylinder with plate tumblers is therefore in practice so far only with / g * higher precision: can be produced, what affects its function and safety ^. It is: also in the production by undesired work gears .. burdened and has no inevitable key-wrench guide and holder. that would make the closing process more reliable,

Advantages of the invention. ■ ■ "- - .-. - - ^.; - ■. -..-" ■ -... The exterior of the security lock cylinder is formed by 'a drawn metal sleeve, preferably made of sheet steel', which can be "flawlessly finished." All that is visible in the opening of the steel sleeve is the inial cylinder in which the slot for receiving the key is located. The inner wall of the cylinder "housing" forms a drawn part, generally made of sheet brass or steel, with an approximately cruciform cross-section, so that the plate tumblers can snap into the bars of the cross at 90 ° and the key can be removed .. The outer sleeve is closed with a solid base plate. The edge of the base plate is designed in such a way that an inner bead of the outer sleeve engages in a groove when the two parts are forcibly pressed together and an absolutely tight connection between the two Represents base plate and sleeve. The coupling piece of the inner cylinder passes through an opening in the base plate and is available without any weakening for receiving the hit. Ewei thread! Holes for screwing the. Cylinder onto a lock cover can be accommodated easily and permanently in the solid .base plate _e -. . -. .

Through the use of drawn parts and turned parts. thus also in the case of the platelet cylinder, a level of accuracy and reliability of the execution can be achieved that is otherwise only possible with. -Pen: Z _: y relieve is common, you get a high-quality security lock cylinder, without this design being more expensive than the one made from ^: "."'■ die cast parts "; ■ "".

Figure 1 represents in the plan and in the side view, the latter in section, the massive base plate (1) with the circumferential; -. . Groove (2), two holes (3, 3a) and the central opening (4) for the. Passage of the inner cylinder end »... -

In Figure 2, an embodiment of the insert sleeve (5) is shown in cross section and in side view. The section shows approximately the 3? Shape of a cross, with the bars. (6) are intended for the emergence of the plate fuses. The two lugs (7y7a) enter the bores (3 / 3a) of the base plate during assembly and prevent the insert sleeve from twisting ». .

The inner cylinder shown in Figure 3 shows the usual shape. It contains five small plate fuses (8) State are visible, and a free end to accommodate the driver for the transmission of the closing process «

Figure 4 finally shows the outer cylinder (9) with. the InD.enwu.lst. (10), which, when pushed onto the base plate (1), is undersized in the Press in the groove (2) *.

When assembling the safety closing cylinder, the procedure is to first place on the inner cylinder (8) with the inserted Key pushes the insert sleeve (5) on so that the two approaches (7 / 7a) point in the direction of the base plate (1) with the openings. . ' (3 / 3a) is pushed over the inner cylinder end so far that the ¥ ulst (11) occurs over the groove (2) and a firm connection of the Of the outer cylinder with the base plate »To slide the outer cylinder (10) on, the key must first be removed from the inner cylinder can be pulled out, in Figure 5 is a section of the assembled Recognize security lock cylinders with plate tumblers » The play-free one is particularly clear.
