Summary of the invention

The invention has for its object to improve a generic cylinder lock manufacturing technology.

The problem is solved by the invention specified in the claims, wherein the dependent claims and in particular individual features of the dependent claims not only represent advantageous developments of the invention specified in the main claim, but are each also independent solutions to the problem.

First and foremost, a cylinder lock is proposed in which each of the two broad sides each has a recess in which a connecting element consisting of at least one component rests. The arrangement of a plurality of connecting elements in Breitseitenausnehmungen brings the advantage of increased stability and offers the ability to use as a form-fitting elements pins, from the narrow side of the cylinder housing be inserted into holes, the pins of U-shaped form-locking elements can be formed, as basically from the EP 1 802 831 B1 are previously known, while there lie the U-legs but in a plane whose surface normal runs parallel to the axial direction, such U-shaped, cramp-like positive locking elements can be used according to the invention, in which the surface normal of the plane in which the U-legs extend perpendicular to the axis of the lock cylinder. The interlocking elements are preferably inserted from a narrow side of the cylinder housing into the holes, the pins in particular intersect the recess and stuck in aligned holes of the two walls. The connecting elements can be arranged between the pins and the bottom of the recess. But it is also envisaged that the pins pass through holes of the connecting element, wherein these holes can be assigned to a pointing to the bottom of the recess rib. To simplify the production, the bores of the rib can form windows facing away from the wall side of the connecting element. The connecting element may be formed by a plurality of individual elements. The individual elements may have overlapping and / or interlocking areas. The individual elements preferably have a connection region in that regions of the individual elements both overlap and engage with one another. The individual elements are preferably in the axial direction one behind the other. A single element may form a rib which is directed towards the bottom of the recess. The rib can engage in a free space of another single element. The free space may be formed by a fork-shaped opening of the single element. The walls of the recess may have bulges, which are arranged in particular toothed rack or wave-like in the axial direction one behind the other. The connecting elements then have congruent projections which engage in the bulges, wherein the individual elements of the connecting elements can be assigned to each other in different axial layers. The Projections or bulges may have a rounded contour line. Preferably, the projections or bulges have a teardrop-shaped outline. The uniform distances of the protrusions or projections allow an arrangement of a single element of a connecting element in different axial layers. For this purpose, the bulges or projections are spaced apart by a same, standardized distance. This distance effectively defines a grid dimension for the axial layers. The edges of the projections and the edges of the bulges are parallel to each other and in particular have a distance from each other, so that the connecting elements can be manufactured with a correspondingly greater tolerance. Preferably, however, it is provided that in each case a saddle is located between the projections. The saddle has a saddle surface, which touches a contact edge, which lies between bulges. If the axis of rotation of the cylinder core extends in an x-direction and the flange region of the cylinder housing extends in ay direction, flanking the saddle surface on the abutment edge stabilizes the housing constructed in the y-direction from a plurality of modules. In one embodiment of the invention it is provided that are provided on the pins attacking clamping elements. The clamping elements can have the task to secure the pins frictionally in the holes. However, the clamping elements can also have the task of applying such elastic tension to the pins that a clamping force is transmitted to the connecting element, which generates a mutually directed clamping force on two modules. The clamping elements are preferably associated with the connecting element. They may be formed by rotary bodies, which are used in wide side open bearing bores. The rotary bodies may have an eccentric portion which engages the interlocking elements. The eccentric portion may have planes meeting in a corner area or a curve, which have different radial distances from the axis of rotation of the clamping element, so that by rotation of the clamping element one of the two levels can be brought into a system for positive-locking element. One level forms a clamping surface. The other level is a release surface. According to a second aspect of the invention, it is provided that at least one connecting element with a positive-locking element is tied to the flange portion of the cylinder housing. On the form-locking element engages a clamping element to clamp the modules in the axial direction to each other. According to the invention, the clamping element is formed by a rotary body. The rotary body can be brought about a rotational axis associated therewith from a release position into a clamping position. In the clamping position, a clamping surface engages the positive locking element. In the release position engages a circumferentially offset to the clamping surface arranged release surface on the positive locking element. The clamping surface and the release surface each have a surface normal, which is perpendicular to the axis of rotation of the clamping element. In the radial direction, the release surface is less spaced from the axis of rotation of the clamping element than the clamping surface. Clamping surface and release surface are connected by a rounding. Preferably, the clamping surface is associated with a pressure edge. The pressure flank extends transversely to the clamping surface and has a surface normal, which extends substantially in the direction of the axis of rotation of the clamping element. In the clamping position, this pressure flank engages the form-locking element in order to exert on the connecting element a force which is directed in the direction of the bottom of the recess in which rests the connecting element. The recess preferably extends in the region of a broad side, but may also extend in the region of the narrow side. By turning the clamping element from the release position into the clamping position, the module is first acted on by means of the clamping surface engaging the form-locking element in the axial direction (X-direction) of the axis of rotation of the cylinder cores. The juxtaposed modules are braced. There is a stiffening of the cylinder lock instead. By additionally a pressure flank in a transverse direction (Z direction) acts on the connecting element, a further tension takes place. In a further development of The invention provides that the interlocking elements and in particular the pins formed by them have latching bends, with which the interlocking elements are frictionally held in the bores. The interlocking elements are preferably formed by bent to a U wire sections. In the mounted position, the U-webs are in recesses in which they can be gripped by means of a tool, such as a blade of a flat-head screwdriver to be pulled out of the holes. With a central single element of a connecting element, which has two arms facing away from each other, preferably two modules of a lock cylinder are connected to each other, between which there is a closing member. By connecting a plurality of individual elements can be produced as it were arbitrarily long connecting elements that do not need to be connected to each other, but each einliegen positively in the recesses. The axial force transmission takes place via the bulges or projections of the wall of the recess, in which engage the connecting element or the individual elements. In the overlapping areas, however, form-fitting connections between the individual individual elements can be produced, this takes place in particular by means of the form-locking elements.

Description of the embodiments

In the in the Figures 1-9 The first exemplary embodiment illustrated is a double-lock cylinder with a cylinder housing 1 which has two modules 1 ', 1 ". Each module 1', 1" has a cylinder core with core pins, wherein the cylinder core 4 is arranged in a cylinder section 3. In a flange portion 2, the two facing away from each broad side 2 ', 16 housing pins and housing pin springs are each arranged in a pin bore.

The two broad sides 2 'have in the axial direction of the cylinder cores 4 extending recesses 5. It may be cutouts. The recesses 5 have axially extending walls 6 and a bottom 7. The bottoms 7 of the recesses facing away from each other 5 of the two broad sides 2 'are parallel to each other. The walls 6 of a respective recess 5 face each other.

The walls 6, which extend in the axial direction, are wavy. They form uniformly spaced protrusions 18. The bulges 18 have the contour of a drop or a wave.

In the recesses 5, a connecting element is arranged in each case, wherein the connecting element consists of individual elements 8, 10. A central individual element 8 has a central region 8 ", in which region the closing element 17 is located. The individual element 8 furthermore has two arms 8 'projecting in each case in opposite directions from the central region 8. The arms 8 'are each in a recess 5 of the two modules 1', 1 ", so that the single element 8, the two modules 1 ', 1" ties together, between the two modules 1', 1 "the closing member 17th The central area 8 "has a forend screw opening.

In the walls 6 holes are provided. A bore 11 is open on both sides. A first opening of the bore 11 extends to the recess 6. The opposite opening of the bore 11 extends to a recess 23 which is arranged in the region of the narrow side of the flange portion 2. The aligned with the bore 11 bore 12 of the opposite wall 6 is a blind hole. The bore 12 extends to adjacent to the cylinder portion 3 of the housing, so that the two holes 11, 12 extend in their entirety almost over the entire radial length of the flange portion 2. There is a plurality of evenly spaced holes in the axial direction 11, 12, in each of which a pin 21 can be inserted in order to tie the connecting element or the individual elements 8, 9 positively in the recess 5.

The pins 21 are formed by U-shaped form-locking elements 20. These are pieces of wire bent into a U-shape. In inserted into the holes 11, 12 state is a U-web 22 in the recess 23rd

The individual element 8 has on its side facing the bottom 7 a rib 14. In this rib are holes 13 which are aligned with the holes 11, 12 and in which the pin 21 is inserted. To the side facing away from the rib 14, the holes 13 are open and each form a window 13 'from.

A single element 10 of the connecting element, which is an end piece, has two fork-shaped sections extending in the axial direction, leaving a free space 15 between them. This fork-shaped free space 15 serves to receive the rib 14. The individual elements 8, 10 have projections 19 facing away from each other, which can engage positively in the bulges 18. The holes 11, 12 are provided here in the bulges 18.

Again FIG. 1a can be seen, the edges of the projections 19 extend at a slight distance of about 0.1 to 0.15 mm parallel to the edges of the bulges 18. This is preferably a tolerance-related game. If, however, an axial pull in the direction X is exerted on the cylinder core during a manipulation attempt, the edges of the bulges 18 can rest against the edges of the projections 19 so as to bring about a form-fitting retention of the modules. To stabilize the modules in the direction Y, it is provided that in the area of the saddles between the projections 19, saddle surfaces 37 rest on abutment flanks 38 between two bulges 18. The position of the saddle surfaces 37 is subject to a smaller tolerance than the course of the projections 19th

The FIGS. 12 and 13 show from the rib 14 protruding teeth 35 which engage in mating second individual elements 8 in recesses 36 which are formed by the forks, between which the free space 15 extends.

The fork-tooth-like portions of the single element 10 have groove-shaped structures which are aligned with the holes 13 and in which the pins 21 extend.

In a bore 25 of the connecting element and in particular of the individual element, a clamping element 24 is rotatably mounted. The clamping element 24 forms a rotary body and is tied with a flanging 27 rotatably in the bore 25. It has an eccentric portion 26 which forms two mutually perpendicular surfaces. The surfaces are a clamping surface 28 and a release surface 29, which are connected together to form a rounding 30. By turning the clamping element 24, either the clamping surface 28 can be brought into contact with the pin 21 or the release surface 29. The clamping surface 28 has a greater radial distance from the axis of rotation of the clamping element 24 as the release surface 29. The system of the release surface 29 on the pin 21st causes no deformation of the pin. If, however, the clamping surface 28 on the pin 21, so the pin is elastically deformed. The rotation of the clamping element 24 from the clamping position to the release position by overcoming a dead center. In the clamping position of the pin 21 is bent in its central region such that its end portions stuck in the holes 11,12, on the modules 1 ', 1 "exert a force that acts on the modules 1', 1" to each other ,

As in particular the FIGS. 14 and 15 can be seen, extends transversely to the clamping surface 28, a pressure edge 41. While the surface normal of the clamping surface 28 and the surface normal of the release surface 29 transverse to the direction of rotation of the clamping element 24, the surface normal of the pressure flank 41 extends parallel to the axis of rotation of the clamping element 24. A flank 42 extending parallel to the pressure flank 41 is associated with the release surface 29. The flank 42 is offset relative to the pressure flank 41 in the axial direction to the axis of rotation of the clamping element 24, that the edge 42 in the release position exerts no force on the form-locking element 20, in the clamping position but the pressure edge 41 exerts a force on the form-locking element 20.

In the release position, the single element, which is associated with the clamping element 24, loosely in the recess 5, so that the interconnected modules 1 ', 1 ", 1'", 1 "" in the Z direction and in the X direction slightly can be relocated. In the clamping position of the clamping element 24, the modules 1 ', 1 ", 1"', 1 "" in the X direction are clamped towards each other, so that the housing 1 is stiffened. By the pressure flank 41 braces the single element 9 in the clamping position against the bottom 7 of the recess 5, a stiffening of the housing 1 in the Z direction is additionally achieved.

The FIGS. 10 and 11 show as a further embodiment of a composite of four modules lock cylinder, wherein the modules 1 ', 1 "are equipped with cylinder cores 4 and the modules 1", 1 "" form extension pieces. A central single element 8 of the connecting element is in an overlapping or engaging connection with a single element 9, which is an extension piece of the connecting element. It forms an engagement or overlapping region, which has fork-shaped sections, as it also has the end piece 10. However, the extension piece 9 also has a rib 14, as it has the arm 8 'of the central single element 8. Several individual elements designed as extension pieces can thus be combined one behind the other in the axial direction, an axial non-positive connection on the one hand being achieved by the projections 19 engaging in the bulges 18 becomes. On the other hand, an axial positive connection but also achieved via the form-locking elements 20, the pins 21 engage in the trough-shaped structure of the forks. Again, the individual elements have 9 clamping elements 24, which cooperate with the form-locking elements 20.

The individual elements 9 and the central single element 8 used as extension pieces can be combined with one another in different axial positions, the spacing of the projections 19 or of the bulges 18 representing a grid dimension. For each bulge 18, a projection 19 is provided. For each bulge 18 and each projection 19 but also a bore 11,12,13 is provided. Not all of the holes 11, 12, 13 must be equipped with a pin 21. It is sufficient if only one positive locking element 20 with a single element 8, 9, 10 cooperates.

In the in the FIGS. 16 to 20 illustrated third embodiment, the connecting element is a one-piece or multi-part, curved sheet with a peripheral arrangement of projections 19, which are assigned to only one of the edges. With a connecting projection 33 engaging in a connecting projection 33, a center piece 8 of the connecting element can be connected to an extension piece 9.

The connecting element 8, 9 has a bottom wall 7 of the recess 5 facing side wall which rests flat against the bottom 7. A side wall facing away from this also runs essentially flat. On this side wall, the form-locking elements 20 are based. Again, the form-fitting elements of U-shaped wire sections are formed and form mutually parallel pins 21. The pins 21 but have a bottom 7 facing out latching bend 21 ', which is supported on the side facing away from the bottom 7 side wall of the connecting element 8, 9 ,

The connecting element 8 has a central bulge, which surrounds a central piece 31, which is arranged at the axial height of the closing member 17.

Between individual modules 1 "', 1" "or 1'" and 1 "connecting pieces 34 may be arranged.

The connecting projection 32 may be a knob which engages a C-shaped eye formed by the connecting recess 33.

Again, the U-webs 22 of the form-fitting elements 20 extend in recesses 23, which extend in the rounding region of the bottom-side narrow side of the flange portion 2. With a blade of a flat screwdriver, the U-webs 22 can be under attack, thereby pulling the staple-like form-fitting elements 20 out of their form-locking positions out. They can be plugged into the holes 11, 12, 13 again without the use of tools.
