DE102008009855A1 - Modular construction system for assembling closing cylinders, connects cylinder housing, housing extensions and sleeve piece using tongue-and-groove joint, where tongue is formed by connecting part that is outwardly inserted in groove - Google Patents

Abstract

The system assembles a cylinder housing (1), housing extensions (2, 3) and a sleeve piece (5) to form a double cylinder. The housing, the housing elongation and the sleeve piece are connected by a tongue-and-groove joint. A groove (8) is arranged in an outer side. A tongue (9) is formed by a connecting part (4) that is outwardly inserted in the groove. The connecting part is clamped in the groove. A borehole extends transverse to an insertion direction of the connecting parts, in a groove region.

Description

The The invention relates to a modular system for the compilation of Lock cylinders.

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

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

Around To achieve this, have the circular cylinder housing parts over a part of the lower periphery of the cylinder core surrounding Housing part a shorter axial length on and the recessed areas are the middle part faces. The middle part is U-shaped in side view educated. The two sides of the recess for the cam located legs are with a bayonet connectable to the web housing parts, wherein the free ends the leg of the middle part in the recessed Regions of the cylindrical cylinder housing parts surrounding the cylinder cores interlock positive and positive and here the circular cylinder housing completely complete.

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.

task The invention is to make the modular system easier and the necessary for the installation of lock cylinders Stock of individual building blocks or components assembled to form the lock cylinder, to reduce.

Solved This object is achieved by a modular system for the compilation of lock cylinders, consisting of the blocks cylinder housing, housing extension and cuff piece, wherein different dimensions of the blocks to double cylinders are composable and the individual components are joined together by tongue and groove joints, wherein the groove in each case starting from an outer side in the blocks is arranged and the springs from the outside into the groove the building blocks usable connecting parts are formed and wherein the connecting parts are clamped in the respective groove.

Preferably is in the blocks in each Nutbereich a across to the insertion direction of the connecting parts extending first bore is provided, arranged in a displaceable pressure ball and that a second, externally accessible, Hole in the first hole opens, in which a grub screw from the outside of the block is screwed, the with the pressure ball, moving it in the direction of the connecting part, is engageable such that the connecting part by the pressure ball is clamped in the groove.

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

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 shifted, in such a way that the ball is pressed in the direction of the tongue or spring.

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