Abstract

Multi-row cylinder cylinder, 1e intended for operating mortise and other door locks. In the body (1) of the cylinder there is a drum (3) which carries rows of tumblers (4) which are provided with grooves (5) into which the shaped holes (7) of the shutters (š) located in the drum (3) fit so that the tumblers (4) passing through the shaped holes (7) of the shutters (6) which rest on ball pins (8) extending into the holes (9) of the non-rotating bottom (2) which closes the body (1). In the drum (3) there are slats (11) with a shaped hole (12) for the key.

Description

This invention relates to multi-row cylinder liners intended κ control door locks as mortise, the _R and others.

Existing manufactured inserts of common safety are mainly produced as single-row inserts in the classic profile, the construction of the closure - key, tumbler, locking pin, spring. Overcoming is accomplished with a collar, force breaking or drilling. These ways of overcoming are partially prevented by the greater segmentation of the key hole, the higher number of tumblers and the finer dividing of the tumbler height. However, this requires high precision of execution so that the adjacent key, the key with one different closure, does not open the insert by manipulation. Drilling attack is made more difficult by inserting hardened pins, balls, etc. Multi-row design is demanding and delicate due to its softness, high precision and material demands.

The above-mentioned problems are overcome by the multi-row cylindrical insert according to the invention, characterized in that a drum carrying rows of tumblers is provided in the body, which are provided with grooves and pass through the slider openings. closed. In the drum are located slats with a shaped hole for the key.

An advantage of the multi-row insert according to the invention is the arrangement of the tumbler and the spring in the radial direction. The tumblers can have a coarse splitting of the groove positions and thus, even with a sufficient number of combinations, it is impossible to open the adjacent shutter. Because multiple rows are used in the insert. tumbling is prevented. Another advantage is a sleeve-shaped support body in which the entire mechanism only rotates. For its simplicity, the body can be hardened and thus the insert is protected against drilling both from the front and the side.

An example of an insert with three tumbler rows is shown in Fig. 1-4. Giant. 1 shows a vertical longitudinal section through an insert. The cut is guided by one row of tumblers. Giant. 2 shows a view of the insert face from the left side of FIG. 1. FIG. 3 is a longitudinal section taken along line AA of FIG. 1; FIG. 4 is a cross-sectional view taken along line BB of FIG. 1.

- 2 2SS 002

The multi-row cylindrical insert (FIGS. 1 - 4) is formed by a hardened cylindrical body 1 with a closed face. The body 2 is closed against the face by a non-rotatable bottom 2. In the cavity formed by the interior of the body 1 and bottom 2 ^{, a} drum carrying radially positioned tumbler rows 2 rotates. Each tumbler has a differently positioned groove 5. The position of this groove 5 is determined by the depth of the closure in the key rib. If grooves £ coplanar with Venturi this can be moved in a thimble 2 in an axial direction as the apertures 1_ damper 2 having a void space in the groove 2 of the tumblers 2 · Axial movement of the damper £ occurs ejecting the ball stud 2 ^{from the} recessed Janíky £ bottom 2 when the drum 2 is rotated. The reciprocating movement of the damper G and the spigot 2 into the well 2 is effected by means of the spring 10. If the correct key is not used, it is sufficient that one tumbler 8 is not aligned with the groove 2 the first tumbler 2 ^{on the} left side) and this cannot move axially, thereby locking the insert. In the front of the drum 2 there are two non-rotatable lamellae 11, in which a key hole 12 is arranged in the axis. These blades 11 prevent drilling into the insert mechanism.

The inserts made in the above manner can be further converted into inserts for master or central key devices, by means of shaped key holes, possibly by changing the pitch of the individual tumblers, or by interconnecting the grooves on the tumbler and the key.
