Abstract

The coupling is designed for cylindrical inserts for building locks and consists of each other rotating left wing (11) and right the wings (10) that are connected a pin (12) fitted with a head (15); the set pin (12) is not through and is firmly attached to the right wing (10) and rotatably with the left wing (11). The arrangement allows the tip to be controlled by the insert (9) a wrench (2) that acts on the clutch in the common axis of rotation of the clutch and the cylinders (5. 8).

Description

Cylinder liner

The coupling is intended for cylindrical locks for building locks and consists of a rotatable left wing (11) and a right wing (10), which are connected by a stepped pin (12) to the head (15), the stepped pin (12) being non-continuous; it is rigidly connected to the right wing (10) and rotatably to the left wing (11).

The arrangement allows the insert to be actuated by the tip (9) of the key (2) which acts on the clutch in a common axis of rotation of the clutch and the cylinders (5.8).

BACKGROUND OF THE INVENTION The present invention relates to couplings of cylinder locks for building locks.

In these inserts, the key tip is located in a common axis of rotation of the cylinder and the clutch. This applies to both single row inserts. even multiline, symmetrical, unsymmetrical and elongated.

In the known single row cylindrical inserts, the key tip is generally outside the axis of rotation of the cylinder. The couplings are controlled directly by the tip of the key or the tip and the leading edge of the key. The split couplings, pushed by the springs into engagement in the tooth head intermediate wall, are couplings located off the axis of the cylinder. _; ~ They are operated using the tip of a key. Furthermore, couplings having a rotation axis are common to the rotation axis of the cylinder. These couplings are divided and connected in the axis of rotation by a tubular rivet, a pin, or their contact faces form an interlocking bayonet closure. As a rule, the individual lengths of the couplings are smaller than the width. More complicated profile profiles are required for reliable operation, with small dimensions of the coupling parts. Their production and machining of cylinder liner cones is difficult or special purpose machines are required. In the case of a multi-row insert, when the tip of the key controls the coupling in the axis of rotation, there are higher demands on the execution of the individual coupling parts, its riveting by a pin, because they cannot be used for riveting the tubular rivet.

The above-mentioned drawbacks are eliminated by a new embodiment of the coupling according to the invention, which is characterized in that the right and left wing of the coupling are rotatable relative to each other and connected by a stepped pin to the head. . The coupling consists of two wings of rectangular cross-section, which are connected by a stub.

The coupling assembly thus constructed has a greater length than a width and thus, even with a simple profile, has reliable guidance and function. Profile

The clutch 250 003 is not disturbed and is sufficiently sized to transmit the torque generated when the building lock is unlocked. The clutch components do not require any single-purpose machines to be manufactured and can be manufactured in universal automatic machines.

An exemplary embodiment of the coupling is shown in the drawings.

is a vertical longitudinal section of a symmetrical double cylinder insert with a key inserted into the cylinder. Giant. 2 shows the coupling in an enlarged view of a vertical longitudinal section. Giant. 3 is a cross-sectional view taken along the vertical plane AA of FIG. 2. FIG. 4 is a cross-sectional view taken along the vertical plane BB of FIG. 2. FIG. 5 is a front elevational view of a coupling usable for asymmetric, elongated cylinders.

The coupling works, for example, in a symmetrical cylinder. The insert consists of a body 1, cylinders 2> θ. ^{and the} control tooth 6. In the housing 1 are disposed tumblers _5> 2 pins and springs ^{in the} cylinder 2 · d 2 ^e 2 inserted key, whose tip 9. controlled clutch. In this way, the cylinder j) and the control tooth 6 are connected by the right wing 10 of the clutch. By inserting the key from the other side of the insert, the clutch is moved and connected with the left wing 11 of the cylinder 3 with the control tooth 6. The right wing 10 and the left wing 11 are rotatable relative to each other and are connected by a stepped pin 22. The stepped pin 12 is inserted in the right wing 10 and is secured by pressing in the hole 14 of the right wing 10 of the clutch. With this connection, even with a single profile, the coupling has sufficient length for reliable guidance and function. The advantage of the fitted pin 12 is that it does not pass through the right wing 10 but is anchored therein as described above. This achieves that the size requirements of the components are reduced to the length of the left wing 11 and the right wing 10 and the head 13 of the shoulder pin 12.

The coupling according to the invention can furthermore advantageously be used, for example, in inserts asymmetrical or elongated. The wings of the couplings and their connection and function remain the same and only the length of the head 15 of the shoulder pin 12 changes (FIG. 5).
