Abstract

Modular system for lock cylinder consisting of the blocks cylinder housing (1), housing extension (2, 3) and Stulpstück (5), wherein different dimensions of the blocks can be assembled into double cylinders and the individual blocks by tongue and groove joints (8, 9) joined together are, wherein the groove (8) is arranged in each case starting from an outer side in the blocks and the springs (9) of externally inserted into the groove (8) of the blocks connecting parts (4) are formed, wherein the connecting parts (4) in the respective groove (8) can be clamped, characterized in that in the blocks in the respective groove area a transverse to the insertion direction of the connecting parts (4) extending first bore (10) is provided, in which a displaceable pressure ball (7) is arranged and that a second, externally accessible, bore (11) opens into the first bore (10) into which a grub screw (12) from the outside of the block one can be screwed with the pressure ball (7), this in the direction of the connecting part (4) moving, so ...

Description

The The invention relates to a modular system for the compilation of lock cylinders according to the generic term of the claim.

From the DE 197 46 580 C2 Such a modular system is known.

in this connection is provided a central part, with which the cylinder housing, the have the cylinder core connected to each other.

Around To achieve this, have the circular cylinder housing parts over part of the lower Circumference of the cylinder core surrounding housing part a shorter axial Length up and the receding ones Areas are facing the middle part. The middle part is in the Side view U-shaped educated. The two are located laterally of the recess for the cam Legs are bayonet-like connectable to the web housing parts, wherein the free ends of the legs of the central part in the recessed Regions of the cylindrical cylinder housing parts surrounding the cylinder cores positive and positive engage and completely complete the circular cylinder housing.

Another modular system is from the DE 100 60 130 A1 can be seen, in which case the closing and non-closing blocks are connected by a substantially rectangular cross member, which is arranged in a recess open from below in the blocks of the housing.

From the DE 196 46 058 A1 is also a modular system refer to, in which the individual blocks are joined together by tongue and groove joints, wherein the groove is arranged in each case starting from the outside in the blocks and the springs are formed by insertable from the outside into the groove of the blocks connection parts, which can be clamped by a pin.

task The invention is to make the modular system easier and the for the assembly of lock cylinders necessary stock of individual components or components, which assembled the lock cylinder to diminish.

This object is achieved according to the main claim in a modular system for the compilation of lock cylinders consisting of the blocks cylinder housing, housing extension and Stulpstück, wherein different dimensions of the blocks can be assembled into double cylinders and the individual blocks are joined together by tongue and groove joints, the Nut is arranged in each case starting from an outer side in the blocks and the springs are formed by insertable from the outside into the groove of the blocks connecting parts and wherein the connecting parts are clamped in the respective groove, characterized
that in the blocks in the respective groove area a transverse to the direction of insertion of the connecting parts extending first bore is provided, in which a displaceable pressure ball is arranged and that a second, externally accessible, bore opens into the first bore into which a grub screw of the Outer side of the block is screwed, which with the pressure ball, this is displaceable in the direction of the connecting part, engageable in such a way that the connecting part is clamped by the pressure ball in the groove.

The Invention will be explained below with reference to the drawings.

there shows

1 a view from below of a double lock cylinder and

2 a schematic side view partially cut.

The double lock cylinder, which in the 1 is shown, consists of the two lock cylinder housings 1 , the cuff piece 5 and two housing extensions 2 and 3 ,

The total required length of the double lock cylinder is achieved via the extension pieces, which are available in 5 mm steps. It is possible in the embodiment housing extensions, for example, 20-40 mm in the block 3 and 5-15 mm at the block 2 ,

From the 1 It can be seen that the individual blocks are held together by tongue and groove joints, with the grooves 8th each in the building blocks - accessible from below (outside) while the springs 9 on connectors 4 are formed. The latter are inserted from the outside into the grooves.

So that a secure and firm connection arises, are in the blocks across to the grooves 8th running holes 10 provided in which are balls 7 are located ( 2 ).

Each of these holes 10 are externally accessible holes 11 assigned, in each case a grub screw 12 can be screwed.

By means of this grub screw 12 becomes the respectively assigned ball 7 in the hole 10 moved, in such a way that the ball in the direction is pressed on the groove or spring.

This results in a tension of the connecting pieces 4 in the groove 8th ,

Claims (1)

Modular system for lock cylinders, consisting of the blocks cylinder housing ( 1 ), Housing extension ( 2 . 3 ) and cuff piece ( 5 ), wherein different dimensions of the blocks can be assembled into double cylinders and the individual components by tongue and groove joints ( 8th . 9 ) are joinable, wherein the groove ( 8th ) is arranged in each case starting from an outer side in the building blocks and the springs ( 9 ) from the outside into the groove ( 8th ) of the building blocks usable connecting parts ( 4 ) are formed, wherein the connecting parts ( 4 ) in the respective groove ( 8th ) can be clamped, characterized in that in the blocks in the respective groove area a transversely to the insertion direction of the connecting parts ( 4 ) extending first bore ( 10 ) is provided, in which a displaceable pressure ball ( 7 ) and that a second, externally accessible, bore ( 11 ) into the first hole ( 10 ) into which a grub screw ( 12 ) is screwed from the outside of the block, which with the pressure ball ( 7 ), this in the direction of the connecting part ( 4 ) is displaceable, engageable such that the connecting part ( 4 ) through the pressure ball ( 7 ) in the groove ( 8th ) is clamped.
