Abstract

The invention relates to a cylinder insert (10) for a mortise lock (100), comprising a housing (12), a first rotatable cylinder core (14), a second rotatable cylinder core (16), and a lock bit (18) which can be actuated by means of the cylinder cores (14, 16). The aim of the invention is to increase the compatibility of mortise locks using simple structural means. This is achieved in that the cylinder insert is designed and developed such that each of the cylinder cores (14, 16) has a coupling section (20, 22) at the end face for coupling to a force transmission element (120, 124) of a multipart locking cylinder system (128). The mortise lock (100) is provided for assembling into a door comprising such a cylinder insert (10).

Description

Cylinder insert for a mortise lock and

Mortise lock with such a cylinder insert

Besehreibung

The invention relates to a cylinder insert for a

Mortise lock, with a housing, a first rotatable cylinder core, a second rotatable cylinder core and an actuatable by means of the cylinder core cam. In addition, the invention relates to a mortise lock for installation in a door with such a cylinder insert.

A cylinder insert and a mortise lock with such a cylindrical insert are known from the prior art, for example in the form of a mortise lock for installation in a door according to DIN 18 250 or DIN 18 251 and a matching cylinder insert in the form of a profile cylinder according to DIN 18 252. Hereby are an opening and

Closing function of doors allows. Also known from the prior art are mortise locks with multi-part lock cylinder systems, for example. In the form of in Asia and especially Japan for

Use upcoming two-piece lock cylinder systems, which are colloquially called "Japanese cylinder halves"

be designated. Such mortise locks with

Two-piece lock cylinder systems with one

Cylinder half with lock cylinder (outside) and another cylinder half with operating knob (inside) are available from the company MIWA (for example MIWA type U9DA-1).

Although mortise locks with cylinder insert

German / European design and mortise locks with two-piece locking cylinder systems perform the same functions, they are not compatible with each other. Thus, mortise locks can only be used with lock components from their respective distribution area. In this case, mortise locks of different types are used, each with adapted keys.

The invention is based on the object with simple structural means in mortise locks the

Increase compatibility.

The invention achieves the above object by a cylinder insert with the features of claim 1. Thereafter, the cylinder insert is characterized in that the cylinder cores frontally each have a coupling portion for preferably positive coupling with a

Power transmission element of a multipart

Close cylinder systems have.

Through this cylinder insert is an adapter for the adaptation of multi-part lock cylinder systems, in particular Asian cylinder halves, to a mortise lock German or European design (DIN EN 18 250 or DIN EN 18 251), in particular with profile cylinder perforation (DIN EN 18 18252) created. By means of the cylinder insert, the torque of an Asian cylinder half, in particular of its power transmission element, on a mortise lock German or European design

be transferred, in particular to the

Sehlosseingerichte.

The invention does not see a conventional one

Profile cylinder (double cylinder) before, but one

new cylinder insert in the form of an adapter. With this cylinder insert can multipart

Lock cylinder systems such as Asian cylinder halves not only with the associated Asian

Mortise locks, but also with mortise locks German or European design can be used. This increases the compatibility of mortise locks. In addition, there is the advantage for users that at

Presence of doors with different

Mortise locks must be carried and used by the adaptation option less key. This facilitates handling.

The cylinder insert has a cam and two rotatable cylinder cores. The rotatable cylinder cores are arranged in particular axially one behind the other, wherein between the rotatable cylinder cores of the cam is arranged. The rotatable cylinder cores are

in particular secured axially by a core retaining ring.

Advantageously, the coupling portion may be formed as a recess. Hereby is with simple constructive means a stable and on

Power transmission elements Asian cylinder halves adapted coupling possibility created. A

positive connection is possible.

Specifically, the recess of the first cylinder core may be formed as a preferably continuous slot. The slot preferably has parallel walls over its entire length. The slot extends

in particular transversely to the axial direction and preferably intersects the axis of rotation of the cylinder core in the middle. The

Slot can be 1-2 millimeters (mm) wide,

in particular of 1.5 mm. The slot can be connected to a power transmission element of an Asian

Cylinder half be coupled with lock cylinder

(Outside or unsecured side).

Conveniently, the recess of the second

Be cylinder core formed as a cylindrical recess with radial slot sections. The cylindrical

Recess is formed in particular concentric to the axis of rotation of the cylinder core. The cylindrical recess may have a diameter of 6-8 mm, in particular of 7 mm. The radial slot sections adjoin the cylindrical recess in particular radially outward and intersect the axis of rotation of the cylinder core

preferably in the middle. The slot sections have

preferably parallel walls. The slot sections may have a width of 2-3 mm, in particular of 2.5 mm. The cylindrical recess with radial

Slot sections can be coupled to a power transmission element of an Asian cylinder half with actuating knob (inside or secured side). Advantageously, the second cylinder core

rotatably coupled with the cam. This creates a structurally simple and stable coupling between the cam and the second cylinder core. As a result, the second cylinder core rotates with an actuation of the Schließbarts always. In concrete terms, the second

Cylinder core one or more projections, in particular axially projecting projections, which engage in the assembled state in corresponding receptacles in the cam.

Conveniently, the first cylinder core can be coupled by means of a coupling with the cam. Hereby, the first cylinder core and the lock bit rotatably

coupled together and decoupled from each other. This allows actuation of the Schließbarts means of the second cylinder core, even if the first

Cylinder core is blocked. This may, for example, be the case when coupled to the one with the first cylinder core

Cylinder half with lock cylinder no key inserted and the lock cylinder is not released for rotation. Specifically, the clutch may comprise a spring (compression spring) and a ball which cooperate with a coupling recess formed in the first cylinder core. In the second cylinder core, a hole, in particular a hole, for receiving the spring and / or the ball can be formed.

In concrete terms, the housing of the cylinder insert in cross-section of the profile cylinder perforations of a

Mortise lock correspond. This is a simple conversion of a mortise lock by installing the

Cylinder insert allows. The case of the

Cylinder insert can correspond in cross section in particular the profile cylinder perforation according to DIN EN 18 252. The Housing may have a transverse to the axial direction oriented passage, in particular threaded. This is an attachment of the cylinder insert with a

Profile cylinder or forend screw on mortise lock allows.

Advantageously, the housing may have an axial length of 12 to 18 millimeters, preferably 14 to 16 millimeters, more preferably 15 millimeters. As a result, the cylinder insert is in built-in a mortise lock German / European design state only slightly, eg. By 0-2 millimeters, from the mortise, especially from the bottom and the lid of the mortise. This leads to low

Dimensions in the direction of the thickness of the mortise lock. In addition, the introduction of torques in the

Cylinder insert thus directly on a bottom or top plate of the mortise and instead is therefore sufficiently supported. The cylinder cores can project out of the housing along the axial direction by 1-2 millimeters in each case, in particular by 1 millimeter.

The object mentioned above is also by a

Mortise lock for a door with the characteristics of

solved sibling claim. With regard to the advantages that can be achieved, the comments on the

referenced cylinder insert described above.

The mortise lock is in particular a door lock with latch and latch according to DIN 18 250 or DIN 18 251. The mortise lock can be designed for installation in butt doors, folding doors and / or tubular frame doors. For further embodiment of the mortise lock in the Related to the cylinder insert described

Serve measures.

The invention will be explained in more detail below with reference to the figures, wherein identical or functionally identical elements are optionally provided only once with reference numerals. Show it

Exploded view of several pages and several partially sectioned views.

1 shows a mortise lock for installation in a door, which is designated overall by the reference numeral 100. The mortise lock has a cylinder insert 10, which will be described below.

The mortise lock 100 is in particular a door lock with a latch 102 and a bolt 104 according to DIN 18 250 or DIN 18 251. The mortise 100 has a Stülp 106, a bottom 108 (see Figure 2) and a cover 110 (see Figure 1). The mortise lock 100 also has a lock mechanism (lock mechanism), which can be actuated via the lock nut 112 and via the cylinder insert 10. This allows the latch 102 and the latch 104 to be operated.

FIGS. 1 and 2 show Asian cylinder halves 114, 116, the construction of which has been described above. The cylinder half 114 has a lock cylinder 118 and coupled to the lock cylinder 118

Power transmission element 120 on. The cylinder half 116 has an actuating knob 122 and a further coupled to the actuating knob 122

Power transmission element 124 on. The cylinder halves 114, 116 form a multipart lock cylinder system 128.

In the installed state, the mortise lock 100 is inserted into a frontal recess in the door leaf and secured via the passages 126 by means of screws on the door (not shown). The cylinder halves 114, 116 can be attached to the door leaf and screwed there, for example.

In the figures 1 and 2 and in particular in Figure 3, a cylinder insert 10 is shown for a mortise 100. The cylinder insert 10 has a housing 12, a first rotatable cylinder core 14 and a second rotatable cylinder core 16. In addition, a cam 18 is provided, which is actuated by means of the first cylinder core 14 or the second cylinder core 16. The first cylinder core 14 and the second cylinder core 16 are each axially secured via a core retaining ring 19 on the housing 12.

The cylinder cores 14, 16 each have a front end coupling portion 20, 22 for coupling with a Power transmission element 120, 124 of a multi-part lock cylinder system 128.

The coupling portions 20, 22 are each formed as a recess 24, 26. The recess 24 of the first cylinder core 14 is formed as a slot 28. The slot 28 has parallel walls and extends over the entire diameter of the first cylinder core 14, in particular centrally through the axis of rotation of the first cylinder core 14.

The recess 26 of the second cylinder core 16 is formed as a cylindrical recess 30 with radial slot portions 32. The cylindrical recess 30 is formed concentrically with the axis of rotation of the second cylinder core 16. The radial slot portions 32 adjoin the cylindrical recess 30 radially outward. The radial slot sections 32 have white parallel walls and intersect the axis of rotation of the second cylinder core 16, in particular centrally.

The second cylinder core 16 is rotatably coupled to the lock bit 18. For this purpose, the second cylinder core 16 has axially projecting projections 17 (see FIG. 4). The cam 18 has at its axial passage 21 receptacles 23 for the projections 17.

The first cylinder core 14 is coupled to the lock bit 18 by means of a coupling 34 (see FIGS. 3 and 4). The cam 18 and the first cylinder core 14 can be rotatably coupled together and decoupled from each other. The coupling 34 has a compression spring 35 and a ball 36 which cooperate with a coupling recess 37 formed in the first cylinder core 14 (see FIG. 4). The coupling recess 37 has a conically widening shape in the direction away from the coupling section 20. The coupling recess 37 may be formed in particular Hablkegelförmig

(Negative form) .

In the second cylinder core 16 designed as a hole hole 38 for receiving the compression spring 35 and / or the ball 36 is formed. The cam 18 has at its axial passage 21 on a ball trough 39, which can embrace the ball 36 in a form-fitting manner.

The clutch 34 operates as follows: If the cylinder insert 10, starting from an unactuated initial position (view group in Figure 4 below) operated by turning the first cylinder core 14, the ball 36 is located between the clutch recess 37 of the first cylinder core 14 and the ball trough 39 of the Schließbarts 18th such that the cam 18 and the first cylinder core 14 are non-rotatably coupled together. Upon rotation of the first cylinder core 14, the cam 18 and also the second cylinder core 16 rotate with.

If the cylinder insert 10 is actuated from an unactuated starting position (view group in FIG. 4, bottom) by turning the second cylinder core 16, the ball 36 is guided along the edge portions of the clutch recess 37 due to the rotation of the second cylinder core 16. The ball 36 moves against the force of the compression spring 35 so long in the direction of the second cylinder core 16 until the compression spring 35th and the ball 36 are completely in the hole 38 (bore) (not shown). The positive coupling of the first cylinder core 14 with the cam 18 is thereby solved. The second cylinder core 16 and the lock bit 18 can then be rotated independently of the first cylinder core 14.

The housing 12 corresponds in its cross section to the profile cylinder perforation 130 of the mortise lock 100. The housing 12 has a passage 40 with a thread.

The housing 12 has an axial length of 12-18 mm, in the exemplary embodiment 15 mm. The cylinder cores 14, 16 protrude from the housing 12 by 1-2 mm in the axial direction.

The first cylinder core 14 can be rotatably coupled via the coupling portion 20 in the form of a slot 28 with the power transmission element 120 of the cylinder half 114 with lock cylinder 118

(positive coupling).

The second cylinder core 16 can be rotatably coupled via the coupling portion 22 in the form of the cylindrical recess 30 with radial slot portions 32 with the power transmission element 124 of the cylinder half 116 with actuating knob 122 (positive coupling).

By the cylinder insert 10 is an adaptation of multi-part lock cylinder systems 128, in particular of Asian cylinder halves 114, 116 on a mortise lock 100 German / European type possible.
